Description

State of the art

Devices for moving an ejector such as a movable furniture part are known, in particular devices which e.g. B. are attached to guide means such as full or partial extensions or fittings for guided movement of the movable furniture part or the associated furniture. The known devices generally include an energy accumulator, with which the movable furniture part is supported during an opening and/or closing movement relative to the furniture body. To eject the furniture part from a closed position in the opening direction, the device is first triggered from a ready position with the energy storage device charged, in order to activate the energy storage device.

Object and advantages of the invention

The object of the present invention is to improve a device for power-assisted movement of a movable furniture part, in particular with regard to secure locking when the energy store is charged and synchronization of two corresponding and cooperating devices that act jointly and identically on a furniture part.

This object is solved by the independent claims.

Expedient and advantageous variants of the invention are shown in the dependent claims.

The invention is based on a device for moving an ejector such as a movable furniture part in an opening direction relative to a body on which the ejector is accommodated, for example a furniture body of a piece of furniture, the ejector being guided in the opening direction and in a is movable relative to the body in the closing direction opposite to the opening direction, wherein the device has a chargeable energy accumulator, with which an opening force can be applied to the ejector in order to move the ejector in the opening direction when the device is installed, wherein the energy accumulator can be brought into a charging state, in which the energy accumulator is charged for a subsequent opening movement of the movement element, and wherein a locking arrangement of the device is provided, whereby the charged energy accumulator remains in the charging state in a locking state of the device, the locking arrangement has a guide track.

Such devices are used, for example, to allow a user easier access to the opened ejector. The closed state of the ejector on the body is secured on the one hand and on the other hand the opening takes place at least with little effort for the user.

The essence of the invention lies in the fact that a resiliently movable spring bar is provided, on which a locking element is present, the locking element and the guide track being coordinated so that the movement of the locking element along the guide track is specified for setting up and releasing the locking state. The spring bar solution is compact and easy to manufacture. In addition, the guide track can be easily adapted to a changeable position of the locking element on the spring bar. With the position of the locking element, its prestressing in one direction can be specified at the same time, or prestressing can be precluded in a basic position of the spring bar. The spring bar can be positioned in comparatively diverse ways and can be spatially arranged in almost any way. only e.g. B. an end portion of the spring bar is clamped for attachment to a bearing point of the spring bar. The other end is free or guided along a guideway. The locking element is preferably present at the free end.

The spring bar is preferably an elongated slender member. The spring bar is preferably a metal wire or a comparatively thin metal bar made of an elastic metal material. Over its length, for example 3 to 5 centimeters, the spring rod has a uniform outer diameter of for example 1 to 3 millimeters. A cross section of the spring bar is, for example, circular or polygonal or the like.

The spring bar is in particular z. B. no elastically deformable component in its longitudinal extent. The spring bar is a z. B. rigid behaving component. The spring bar is, for example, a longitudinal extension of the spring bar itself laterally z. B. arcuate bending spring member. In its longitudinal direction, the length of the spring bar is unchangeable. The spring bar cannot be stretched or lengthened or compressed in its longitudinal extent. Only the shape of the spring rod can be changed by the lateral bending, especially with no tensile or compressive force laterally or to one side or to the right or to another side, e.g. B. bent to the left. The spring bar is laterally bendable in two opposite directions. In other directions transverse to the length of the spring bar, this is mechanically clamped in such a way that bending in these directions is not possible or does not take place. A tensile or compressive force on the spring bar is prevented in these directions.

In particular, the spring bar is not a helical spring or the like that deforms elastically in its longitudinal direction.

The spring bar is, for example, a rigid, deformable, elongated component. The spring bar can be bent in the event of a compressive or tensile load that acts on the outside of the spring bar at an angle or transversely to the longitudinal axis of the spring bar. The bending of the spring rod and thus the position of the locking element present thereon is preferably adjusted by the locking element resting on the guide track. For this purpose, the locking element moves relative to the guide track. The remainder of the spring rod, apart from the fixed bearing section, preferably remains without pressure or tension. The locking element remains in a relative position, e.g. B. with charged or discharged energy store, until further movement of the locking element. Sections of the guide track are preferably formed on various components of the device, which come into contact with the spring bar during a functional sequence of the device. Depending on this, the spring bar is bent in a first lateral direction to the longitudinal axis of the spring bar or in a second lateral direction of the spring bar or in its straight, relaxed basic position of the spring bar. The function of the spring rod and the locking element present on it depends, for example, on its orientation, i.e. whether it is bent to one side or to the other side, then in each case prestressed in the direction of the basic position, or whether it is in a straight alignment in the basic position, then it is not biased in one direction. The function of the spring bar and the locking element present thereon is particularly dependent on the respective position of the spring bar relative to the guide track.

When the spring rod is bent, it remains in its position with the locking element, since z. B. presses a portion of the track against the locking element. The deflection or bending of the spring rod changes when z. B. the locking element comes free from its system on the section of the track. Then causes the bias that the spring rod in its z. B. basic position or snaps back into another position.

The spring bar is reversible or elastically yieldable from the unloaded basic position of the spring bar, for example by bending laterally. For example, the spring bar is elongated and straight in the home position and is arcuate under bending loading. For example, preferably a portion of the spring bar, such as. B. a first end portion of the spring rod, fixed or clamped z. B. at a bearing point such as a fixed bearing. The fixed bearing is preferably movable relative to the rest of the device, preferably on a linearly displaceable ejector of the device. For example, another portion of the spring bar, such as e.g. B. a second end portion of the spring bar, movable, for example, freely along an arcuate path corresponding to the deflection of the spring bar movable or deflectable.

The locking element is present or formed on the other section or on the second end section, for example opposite the first end section. The locking element is z. B. integrally formed with the spring bar or attached thereto.

When the device is in the locked state, the locking element is advantageously held at one point along the guideway and secured against further movement along the guideway under tension, with the locking element being in contact with a contact section of the device in the locked state. The contact section is part of the guide track, for example. Alternatively, the contact section is part of another guide for the locking element. The locking state can thus be established at a predeterminable point along all possible positions of the locking element. Holding or locking preferably takes place with the spring bar bent in a laterally prestressed manner. This supports the safe retention of the locked state. The contact section is, for example, in the arranged state of the device, for example on a body or an ejector, a stationary section of the device or a movable section of the device.

Another advantage results when the contact section is formed on a sliding element of the device, the sliding element being designed to be movable relative to the guide track. The contact section is thus separated from the guideway. Depending on the position of the sliding element and depending on the position of the spring bar, the contact section comes into contact with the locking element. Starting from the locking state, a control function of the locking element can thus be implemented, for example as a function of the established and/or canceled locking state. For example, in the locked state, the slider is in a waiting position. The contact section or the sliding element preferably blocks the opening raise the locking state. The locking state can preferably be canceled by a touch-latch functionality of the device, with the ejector being moved somewhat in the closing direction like the furniture part. The spring bar is thereby offset somewhat and the locking element is also offset with it. The charged energy accumulator then applies a force to the sliding element in the opening direction via the spring bar and the locking element that is in contact with the sliding element. The sliding element is entrained somewhat in the opening direction with the spring bar moving in the opening direction. At the same time, the force effect of the charged force accumulator causes the spring bar to be moved in the opening direction. This takes place in that the energy accumulator pulls on a displaceable ejector of the device and the spring rod is accommodated on the ejector. The movement of the spring bar is also transmitted to an ejector, in that the locking element moves the ejector along with it and this moves in the opening direction and moves the ejector in the opening direction, which causes the desired ejection movement of the furniture part in the opening direction.

When the locking state is released, with the locking member in the unlocked state, the sliding member is movable to a position in which the sliding member has a e.g. B. occupies operating position, with which a function of the device is linked, for example, a synchronization function, which is described below.

The touch-latch function is known, in which case the locking state can be canceled from the outside by a short movement of the ejector, such as the furniture part, from the stationary closed position of the furniture part in the closing direction.

The guideway is z. B. a circumferentially closed path which is coordinated so that the locking element can be repeatedly moved along the guide path in the same direction of movement as often as desired. The guide track is preferably formed in a housing plate of a housing of the device, for example on the inside thereof. It is also preferred that the corresponding guideway is also formed in a further housing section, for example in an opposite further housing plate. In this way, the movement of the locking element in a plane parallel to the housing plates can be implemented, advantageously guided on both sides on the guide track.

In the locking state, the locking element is preferably prestressed, under the effect of the charged energy store and due to a spring tension of the laterally deflected spring bar. The locking state is thus secured against unintentional cancellation. It is thus advantageously realized that force components, which contribute to the movement of the spring bar and are attributable to different force elements, act on the spring bar and thus the locking element. On the one hand, the energy storage device, which acts on the spring rod via the ejector in the charged state or when discharging, the ejector being movably accommodated on the device and entraining the spring rod since it is attached to the ejector. In addition, when the spring rod is laterally deflected or elastically bent, which is possible in two opposite directions, a further force acts on the locking element. This is because the bent spring bar is prestressed in the direction back into a basic or straight neutral position of the spring bar when the spring bar is straight. The spring bar also transmits tensile forces in the longitudinal direction. The spring bar is thus a compact and multifunctional element of the device.

The position of the spring bar, which is dependent on the operating state, or the time sequence of the lateral deflection of the spring bar, is set up with the locking element that can be moved along the guide track and other guide sections. This depends on the position of the locking element along its path of movement. The guide track and further track sections preferably form a curve control, with which a movement of the locking element connected to the ejector can be predetermined. The locking element can, for example, be moved in a positively controlled manner in a movement loop that can be repeated. This relates to the moveable components of the device as they move, starting from a charged state of the energy store, via the touch-latch release of the unlocking, the subsequent power-assisted movement of the ejector and ejector by discharging the energy store and then loading the energy store through Movement of the furniture part and thus of the ejector and ejector in the closing direction.

It is advantageous that the device is designed as a furniture part opening device for a piece of furniture with a furniture part and a furniture body, the device comprising a component with a housing, the force accumulator, the locking arrangement and the sliding element. A piece of furniture such as a piece of furniture with drawers or a flap cabinet can thus advantageously be provided with an ejection device. Preferably, the device comprises an ejection function with an ejection device for opening the furniture part from a Closing position of the furniture part relative to the furniture body.

The device is preferably implemented with a touch-latch function and with a damped retraction arrangement.

When the device is installed, the closing direction or opening direction of the furniture part corresponds to the closing direction and opening direction of the movable parts of the device. The guide track is preferably fixed, for example on the housing of the device.

It is also advantageous that the device has an ejector that can be moved relative to the housing and that can be driven in the opening direction from a retracted starting position on the device under the action of the energy store that is being discharged The closed position on the furniture body can be moved in the opening direction by the ejector, the ejector being coupled in movement to the ejector, the energy storage device being able to be charged by moving the ejector back into the starting position on the device. In particular, the ejector forms the interface of the device to the ejector or to the furniture part. When the device is installed, the ejector is movable on the device in the opening direction and closing direction of the furniture part, correspondingly in two opposite directions.

According to an advantageous modification, the locking element is guided along a slideway in addition to being guided along the guideway, with the slideway being formed on the ejector.

The locking element is guided, for example, on three guides or simultaneously on three component sections of the device. The three component sections include z. B. a guide on the housing plate which exists positionally fixed with the attached device, such as a cardioid on the housing. Another guide is on the sliding element, which can be moved. A third guide is the link guide on the ejector and also acts on the locking element. The guides overlap.

A complex control function of the locking element can thus be set up. The slide track has z. B. a straight path section, which is preferably aligned parallel to the direction of movement of the ejector or the furniture part when the device is mounted and / or an inclined path section, based on the direction of movement of the ejector or the furniture part. The link track extends lengthwise in the ejector and has two opposite track ends. Since the ejector z. B. is movable or displaceable relative to the housing of the device, the link track is movable relative to the housing. With the link track, it is possible in a coordinated manner to allow or prevent a relative movement between the ejector and the locking element. The locking element is guided and can be moved along the link track. The link track preferably has two straight track sections and two track sections that are oriented at an angle. In relation to the installed state viewed in the opening direction, a first straight path section is followed by a first oblique path section, then a second straight path section, then a second oblique path section. The two straight track sections are offset parallel to one another, along which the locking element can be moved. The two parallel, straight track sections are connected to one another via the track section that is oriented obliquely thereto.

In addition to being guided along the guide track, the locking element is advantageously guided along a guide flank, the guide flank being formed on the sliding element. A movement control can thus be set up in a predetermined manner between the sliding element and the spring rod. Due to the mobility of the sliding element, the guiding flank can move relative to the housing. The leading edge closes z. B. to the investment section.

It is also advantageous if the spring rod is accommodated on an ejector of the device that is movable in the closing direction and opening direction of the device. The ejector is, for example, plate-like and linearly displaceable in the opening and closing directions, that is, it can be moved back and forth between a first and a second stop position. The ejector is matched to the ejector in such a way that the ejector and the ejector are movement-coupled at times. When the energy store is discharged, the ejector takes the ejector with it in the opening direction. When the energy store is loaded, the ejector takes the ejector with it in the closing direction.

Advantageously, the energy accumulator acts on the ejector. The ejector is z. B. linearly reciprocating in the opening and closing directions on the device. This allows the movement of the ejector and the loading and unloading of the energy store to be coordinated with one another. The condition and position of the spring rod is determined by its attachment to the ejector Can be set up depending on the loading status and/or movement status of the ejector.

According to another embodiment, the locking element is matched to the guide track and the link guide in such a way that when the ejector moves in the closing direction to load the energy store, the link track makes contact with the locking element and the stop takes the locking element with it in the closing direction, with the ejector moving in the Closing direction is movable.

The respective desired position of the locking element and thus a control of the device to be carried out with it in its effect on the furniture part is determined by the guideway and the link guide, which also acts as a guide for the locking element, which, for example, interact in a superimposed manner and specify the position of the locking element during operation of the device determinable.

The movement of the ejector in the closing direction is z. B. coupled to the furniture part, which is manually moved, for example, by a user in the closing direction, optionally supported by a self-closing mechanism.

When the energy store is loaded, the spring bar is at one end of the link track, so that the ejector pulls the spring bar in the closing direction and thus also entrains the ejector in the closing direction. The energy accumulator is thereby loaded, with one end of the energy accumulator being present in a fixed position on the device and the other end of the energy accumulator acting on the ejector and thus being stretched or lengthened. At the end of the clamping or loading process, the locked state is assumed with the energy store loaded.

The locking element, preferably at an end section on the spring bar, for example a bent end piece of the spring bar material, is bent away to the side during loading, which can be predetermined with the guideway and the link guide. Due to the spring bar being bent away laterally in one bending direction of the spring bar, the spring bar is pretensioned in the other bending direction. With the movement of the ejector, a bending position of the spring rod can also be specified.

The locking element experiences, for example, being carried along by the ejector, taking the ejector with it, as a result of which the energy accumulator is loaded. When the energy accumulator is loaded, the guide track or link guide opens a path in the direction of the preload of the locking element, so that the locking element gives way due to the spring bar preload and is blocked pending on a section of the guide track. This prestressed position occurs under the tensile force of the energy store in the opening direction. The ejector then moves a little further in the closing direction until the slotted link guide clears a path for the locking element and, due to the spring rod preload that continues to act, moves out of the blocked position and into the locking state or the "0 position". The locking element is located at a point that is defined or delimited by a section of the guideway, the slideway and the contact section on the sliding element. There is a superimposition of three different guides acting on the locking element.

The ejector is movement-coupled to the ejector when loading and/or discharging the energy store.

When loading, a tensile force can be transmitted from the ejector to the ejector by moving the ejector in the closing direction with the spring bar. This lengthens or loads the energy accumulator, which engages the ejector with one end. When the furniture part is opened after the touch-latch has been triggered, the spring bar takes the ejector with it in the opening direction, with the locking element being in contact with the link guide of the ejector.

Another advantage is that the sliding element is designed to synchronize an unlocking of the charged energy store of the device with another corresponding device provided on the ejector for moving the ejector in the opening direction.

Concretely, the sliding element is a linearly movable synchronizing component such as a synchronizing plate. The slide member is moved from a first position such as a start position as soon as the lock state is unlocked in the touch latch operation. To transmit the movement of the sliding elements or from one device to the second device at a distance therefrom and thus for synchronization, an elongate connecting element is connected to the sliding elements on both sides in such a way that a movement of the first sliding element in the opening direction causes a rotary movement in a first direction of rotation of the connecting element. The connecting element thus rotates the sliding element of the other device in such a way that the sliding element, which is also present in accordance with the locking state of the other device, moves synchronously or at the same time as the first sliding element and thus cancels the locking state on the other device. Both Devices that are locked for unlocking when the force accumulator is charged are unlocked synchronously at this moment, so that both devices or with double energy storage effect or with the respective energy storage device eject the furniture part in the opening direction.

It is also advantageous if a restoring element is provided, which acts on the sliding element and provides a restoring force in order to bring the sliding element into a starting position. This ensures that before the energy store is loaded again, the sliding element is in its correct or first position. Because in the previous synchronization, the sliding element moves from a first position or z. B. the starting position in a second position and thereby rotates the connecting element. Without a restoring element, it could happen that the sliding element remains in the second position. The restoring element provides, for example, a tensile force in the closing direction on the synchronization element.

The invention extends to a piece of furniture with a furniture part and a furniture body, the furniture part being movable relative to the furniture body via guide means, a device being provided according to one of the configurations described above.

The ejector designed as a furniture part is accommodated via the guide means on the furniture body formed as a body. The device on the furniture is designed as a furniture part opening device.

A piece of furniture 50 with a box-shaped body or furniture body 51 and a drawer 53 that can be moved via guide means 52 is in 1 shown. The drawer 53, which forms an ejector, comprises a drawer bottom 54, a drawer front 55, two opposite side walls 56 and a drawer rear wall 57. To guide the drawer 53, there are two equally effective guide means 52 between each side wall 56 of the drawer 53 and an associated body side wall 58 available. Two identical inventive devices 1, 2 (shown in phantom) are arranged on the underside of the drawer base 54, which together and synchronously serve to move or eject the furniture part designed as a drawer 53 in the opening direction M1. The devices 1, 2 are each a furniture part opening device.

The device 1 is used for power-assisted ejection of the drawer 53 over a partial distance of an opening movement of the drawer 53 from a closed position relative to the furniture body 51 in the opening direction M1 of the drawer 53. The drawer 53 can be pulled out via the guide means 52, for example two identical partial or full extensions , Slidably mounted on the furniture body 51 in the opening direction M1 and in the opposite closing direction M2. The device 1 can alternatively be arranged on the furniture body 51 or on the guide means 52 of the piece of furniture 50 .

The same applies to the device 2, with particular reference being made to the device 1 below.

The device comprises a base plate 3, a power unit 4, a ratchet component 5, an ejector 6 and a power accumulator 7 (see Fig. 2 ). The base plate 3 forms part of a housing plate of the device 1. In the base plate 3, the guideway 8 is formed. Also provided in the base plate 3 is a recess 9 for receiving an ejector 10, on which the energy accumulator 7 preferably engages. The ejector 10 can also be referred to as an ejector. The energy accumulator 7 comprises at least exactly one helical spring 11, preferably two helical springs 11, 12 which can each be used individually and which are each attached to the ejector 10 at one end. The other ends of the helical springs 11, 12 are advantageously connected to a bearing part 13, the length and thus the pretensioning force of the tensioned helical springs 11, 12 being able to be adjusted by means of an operating section 14. A spring bar 15 is arranged on the ejector 10 . A point 62 on the ejector 10 (see 2 ) a fixed bearing of a clamped end of the spring rod 15, the ejector 10 being linearly displaceable on the device 1. The spring rod 15 is connected to a free end z. B. a bent end portion of the spring rod or the spring rod component is preferably guided on or along a heart-shaped curve 16 designed as a guide track, which is formed in the base plate 3 . The bent end section of the spring bar 15 forms a locking element 61 of a locking arrangement for locking the charged energy accumulator 7. The locking element 61 can also not be present on the spring bar 15 in one piece.

Furthermore, the spring bar 15 can be moved via its locking element 61 along a link path of the ejector 6 designed as a guide link 17 . During the movement of the spring bar 15 or its end section with the locking element 61 along a link track or a guide slot 17 in the ejector 6 and/or the guide track or the heart curve 16 in the base plate 3, a sliding element or synchronization organ designed as a synchronization plate 18 is also moved . A contact section 59 and a guide flank 60 for guiding the locking element 61 are formed on the synchronization plate 18 or on the sliding element. The contact section 59 and the guide flank 60 accordingly temporarily come into contact with the locking element 61.

The synchronizing plate 18 is linearly movable in directions P1 and P2. The synchronization plate 18 is connected to the base plate 3 via a spring 19 . The spring 19 forms a restoring element for the synchronization plate 18 or the sliding element for restoring the synchronization plate 18 to a starting position. When the synchronization plate 18 moves, a connecting element designed as a synchronization element 18a is set in rotation D1, in the direction of rotation dependent on the movement of the synchronization plate 18 towards P1 or P2. The synchronization element 18a is on the other in the 15-17 end not shown is connected to the further device 2 or to a synchronization plate 18 of the device 2.

The base plate 3 is covered by a cover element 20, the cover element 20 forming a counter-plate almost corresponding to the base plate 3, whereby an interior of the device 1 is enclosed on both sides and on the peripheral narrow sides, with individual areas being open to the outside. The cover element 20 forms at least part of a further housing plate of the device 1.

The cover element 20 has a control cover 21 which is formed in two parts or in one piece with one another. The control cover 21 preferably has a further heart-shaped curve (not shown), which in the assembled state preferably provides a guideway corresponding to the heart-shaped curve 16 for a further angled end of the spring rod 15 in the base plate 3 . This enables the spring bar ends of the spring bar 15 to be guided reliably on both sides.

The guide track 8 is designed in the base plate 3 in order to move the latch component 5 along the guide track 8 . The guide track 8 preferably has two separate guide tracks 8 in the width direction of the base plate, which is aligned perpendicular to the opening and closing movement of the ejector 6 . The guide track 8 can be divided into two guide areas 22, 23, preferably in exactly two guide areas. The first management area 22 is in the Base plate 3 is formed in a recessed manner in relation to a surface side of the ejector 6 . The second guide area 23 preferably runs in the opening direction P1 and closing direction P2 of the ejector 6. The direction P1 correlates with the direction M1 and the direction P2 correlates with the direction M2.

The two guide areas 22, 23, which are aligned at an angle to one another, together form an L-shape, for example, with the longer leg forming the second guide area 23 and the shorter leg forming the first guide area 22.

In 3 a receptacle in the base plate 3 for a second end of the power unit 4 can be seen. The first end of the power unit 4 is connected to a connecting section 24 of the latch component 5 (see Fig. 4 ). The pawl component 5 also has a guide member 25 which can preferably be moved permanently in the second guide area 23 of the guide track 8 . The guide member 25 protrudes from the pawl component 5 and is preferably cylindrical or bolt-like. Guide members 25 are preferably present on both sides of the latch component 5 and can be moved along the guide tracks 8 spaced apart in the width direction. Advantageously, the guide element 25 can be moved along the second guide area 23 of the guide track 8 while being supported. The latch component 5 also has a guide element 26 which is moved from the first guide area 22 into the second guide area 23 during an opening movement of the ejector 6 . As a result, a hook section 27 of the latch component 5, which is located above the guide element 26 in the direction of the ejector 6, can be pivoted in the direction of the ejector 6. The pawl component 5 also has a hooking contour 28 which can interact with the ejector 6 . The hooking contour 28 is preferably aligned transversely to the opening and closing direction of the ejector 6 .

The ejector 6 has a depression 29 on an underside, which is directed towards the base plate 3 (see Fig. 5 ). The recess 29 is preferably groove-shaped, with the longitudinal extension L of the recess 29 being aligned in the opening and closing direction of the ejector 6 . The connection section 24 of the latch component 5 is preferably accommodated in the depression 29 . The recess 29 has a surface which is formed in the width direction and height, with an edge contour 30 which can be coupled to and decoupled from the hooking contour 28 of the latch component 5 .

A stop element 31 is formed on the ejector 6 and interacts with the drawer 53 or a drawer rail of the guide means 52 . After unlocking the charged energy store 7 that is held locked, an opening movement of the ejector 10 moves the ejector 6 and this via the stop element 31, by the force of the charged energy unit 4 and/or the energy store 7, moves the drawer 53 in the opening direction P1. During the closing movement P2, the drawer 53 or a section of the drawer rail presses against the stop element 31 of the ejector 6, as a result of which the ejector 10 and thus the energy accumulator 7 acting on the ejector and the energy unit 4 are loaded.

In the 6 the device is shown in the closed position. Here is in the 6 until 8th the cover element 20 is not shown for the sake of clarity. In 6 the control cover 21 is not shown in addition. In the 7 , 8th , 10 , 11 , 13 and 14 the ejector 6 and the pawl component 5 are shown only in sections for a better view of the arrangement of the pawl component 5 in the guideway 8.

According to the 6 until 8th It can be seen that the pawl component 5 is covered from above by the ejector 6 in the closed position. The connecting section 24 of the latch component 5 is accommodated in the recess 29 of the ejector 6 , the edge contour 30 of the recess 29 not interacting with the hooking contour 28 of the latch component 5 . The guide element 26 of the pawl component 5 is in the closed position in the first guide area 22, so that the power unit 4 is tensioned to the maximum extent. The guide element 25 is supported on the guide track 8 of the second guide area 23 .

The spring bar 15 is arranged in an arcuate section of the heart curve 16, whereby a movement of the spring bar 15 in the opening direction P1 is not possible because the synchronization plate 18 blocks this movement (see Fig. 6 , 15 ). The device 1 has reached a zero position, and the drawer 53 rests in the closed position on the furniture body 51. The pretension acting in direction P4 of the spring bar 15, which is bent against P4 due to the link track or guide link 17 and the contact section 59, is in 15 indicated, in which the course of the bent spring rod 15 is also indicated by dashed lines. The locking state is reached in this case, in that the locking element 61 is in contact with the contact section 59 .

The drawer 53 is opened or ejected from the outside by a user who uses the touch-latch function and pushes the drawer 53 or the drawer front 55 of the drawer 53 inward in the closing direction M2, causing the ejector 6 to move with the Ejector 10 moves in the closing direction P2.

The spring bar 15 is then also moved in the direction M2 or in the closing direction P2 by the ejector 10, as a result of which the spring bar 15 is no longer blocked by the synchronization plate 18. The locking element 61 is moved past a corner of the synchronization plate 18 by the slight movement in direction P2 and snaps in direction P3 due to the pretension of the elastically bent spring rod 15 and is under the tensile force of the energy accumulator 7 on an end face 18b of the synchronization plate 18. The spring end or the locking element 61 encompasses the end face 18b of the synchronization plate 18, which can now be moved in the opening direction P1. The force accumulator 7 is thus discharged and the spring rod 15 is moved along the heart curve and a side flank or the guiding flank 60 on the synchronization plate 18 in the opening direction P1. When the spring bar 15 moves in the opening direction P1, the synchronization plate 18 and the ejector 6 are also moved in the opening direction P1. The drawer 53 is carried along or ejected. The first opening position is then reached (see Fig. 9 ). In the first open position, the force accumulator 7 is discharged.

In the 10 and 11 the guide element 26 of the pawl component 5 is still in the first guide area 22 of the guide track 8 and thus the hook section 27 is not yet deflected in the direction of the ejector 6 . The fact that the edge contour 30 of the recess meets the hooking contour 28 of the pawl component 5 causes the pawl component 5 to be moved in the opening direction P1, as a result of which the guide element 26 is moved along the guide track 8 into the second guide region 23. The pawl component 5 can be pivoted about the guide member 25 which rests on the guide track 8 in the second guide area 23 . When the pawl component 5 is pivoted, the hook section 27 can be deflected upwards in the direction of the ejector 6 , the hook section 27 engaging behind an end contour 32 of the ejector 6 . As soon as the guide element 26 of the latch component 5 reaches the second guide area 23 of the guide track 8, the power unit 4 can be discharged. This moves the pawl member 5 in the opening direction P1. The ejector 6 is also moved in the opening direction P1 until the second opening position is reached (s. 12 until 14 ). The drawer 53 is moved in the opening direction P1 by the stop element 31 of the ejector 6 .

In the second open position, the power unit 4 is unloaded. In the 14 it can be seen that the edge contour 30 of the depression 29 rests against the hooking contour 28 of the latch component 5 . Furthermore, the guide element 25 and the guide element 26 are located in the second guide area 23 of the guide track 8 , the guide element 25 being spaced horizontally from the guide element 26 . The guide element 25 is further forward in the opening direction P1 compared to the guide element 26.

During the opening movement from the first opening position (s. 9 ) to the second opening position (see 12 ) the spring bar 15 is first moved along a first straight area 33 of the guide link 17 of the ejector 6 . The spring bar 15 is fixed according to a position on the heart curve 16 . With further movement in the opening direction P1, the spring bar 15 is moved to the right or in the direction of the power unit 4 by a lateral area 34 of the guide slot 17 and then moved along a second straight area 35. In this way, the spring rod 15 reaches the right-hand section of the heart curve 16 (see Fig. 12 ) and the synchronizing plate 18 can be pulled back to the initial position by the spring 19.

During a closing movement of the ejector 6 in the closing direction P2, i.e. in particular when the drawer is thrown or pushed shut by the user and this takes the ejector 6 with it in the closing direction P2, possibly supported by a force-providing dampened automatic closing mechanism, the spring rod 15 is first moved along the second straight line Area 35 of the guide link 17 is moved until the spring rod 15 rests against the transition between the second straight portion 35 and the lateral portion 34 . If the spring bar 15 rests against the transition, the spring bar 15 and thus also the ejector 10 with the energy store 7 can be moved in the closing direction P2 with a further closing movement of the ejector 6, with the energy store 7 being charged. The spring bar 15 is guided along a straight section 36 of the heart curve 16 on the right until the end of this section 36, then the spring bar 15 follows the heart curve 16 and moves to the left in the direction of the spring 19. The spring bar 15 thus also reaches the first straight line Area 33 of the guide link 17. The spring bar 15 is locked in the heart curve 16, whereby the spring bar 15 is moved along the first straight area 33 as the ejector 6 closes further. If the ejector 6 closes further, the closed position is reached (see Fig. 6 ).

The power unit 4 is loaded directly by the hook portion 27 abutting the end contour 32 of the ejector 6 when the ejector 6 is moved in the closing direction P2. In this case, the guide member 25 and the guide element 26 along the second guide portion 23 of Füh Rough path 8 are moved until the guide member 26 reaches the first guide portion 22 and is pivoted downwards. As a result, the hook section 27 of the latch component 5 is no longer in contact with the end contour 32 of the ejector 6, so that the ejector 6 can be moved in the closing direction relative to the latch component 5. The connection section 24 of the pawl component 5 is thereby moved along the depression 29 of the ejector 6 .

If the synchronizing plate 18 is not pulled in the closing direction P2 by the tensioned spring 19, a stop on the ejector 10 comes into contact with a counter-stop on the synchronizing plate 18 when loading the energy accumulator 7. This returns the synchronizing plate 18 to its starting position.

15 makes it clear that stop means 37 with a stop surface 38 on the ejector 10 or on the ejector and a stop surface 39 on the synchronization plate 18 are present. According to 15 are the two stop surfaces 38 and 39 in the direction of movement of the ejector 10 or in direction P1 or P2 away from each other or a few millimeters apart. This is because the synchronization plate 18 is retracted into the starting position and ready for a synchronization process due to the tension spring force of the spring 19 that has become active.

The stop means 37 have a projection 10a projecting on an outer contour of the ejector 10 that can be coupled to the ejector 6 .

The synchronizing plate 18, which can be moved back and forth in the directions P1 and P2, is under the tensile force F1 (see Fig. 15 ) by the spring 19, e.g. B. a coil spring, acts in direction P2 on the synchronization plate 18, according to the starting position 15 delay.

The 16 and 17 illustrate the driving contact between the stop surfaces 38 and 39 when the synchronization plate 18 is still in an adjustment position, ie it remains in this position after a synchronization movement or remains stuck, despite the spring 19, what 16 , 17 show. This can result, for example, from friction effects when the force of the spring 19 is not sufficient, the synchronization plate 18 from the 16 , 17 shown adjustment due to z. B. To return static friction to the starting position. When the drawer 53 is closed and the ejector 6 is moved and the ejector 10 moves in the direction P2, the ejector 10 takes the synchronization plate 18 with it into the starting position. Here, the stop surface 38 presses against the stop surface 39 and forces the synchronization plate 18 in direction P2. The synchronizing plate 18 is forcibly returned to the starting position, assisted by the force F1.

Thereafter, with the drawer at rest closed, the synchronization plate 18 is in the starting position. Then, the next time the closed drawer is operated, the synchronization plate 18 can be moved with the unlocking of the charged energy store 7 by means of the touch-latch function.

Without the stop means 37, the possibility of the synchronization plate 18 remaining in the adjustment position and no synchronization taking place during the next touch-latch process would not be reliably ruled out.
