Abstract

The fitting (1) has an inner body (2) and an outer body (3) joined to the inner body, of which at least one has a housing protrusion facing the door (8) panel and that is designed to fit into a cylindrical hole provided for a lock cylinder instead of the lock cylinder. Both inner and outer bodies can have protrusions that protrude into the hole from either side.

Description

The The present invention relates to a set of fittings according to the preamble of the main claim.

Such a set of fittings is the subject of EP 1 256 671 A2 ,

This known fitting set has an inner door plate, an outer door plate and put on a rosette.

The Rosette houses certain electrical / electronic assemblies, around a lock cylinder to be controlled with an electrically activatable blocking element.

Furthermore, from the DE 44 07 244 C1 an electrically controllable mortise lock is known which can be actuated via a handle provided on both the inside of the door and on the outside of the door, for example a door handle.

In order to the inside or outside Actuating handles perform different functions can, the lock nut is divided, so that - in this Case - the Door at any time via the handle provided on the inside can be opened like a Escape door, while the outside Handle only becomes effective by activating a driver clutch.

task of the present invention is the known fitting set in particular for use in combination with an electrically controllable Mortise lock like this to train that at simplified assembly a high degree of security against unauthorized persons There is access.

This Solves task the invention with the features of the main claim.

Out The advantage of the invention is that the access control device, the at least one electrically controllable mortise lock and the Fitting set according to the invention comprises the use of different identification features or Identification feature carrier for access authorization.

This Advantage is achieved by omitting the lock cylinder that of the lock cylinder originally occupied space at least partially by the inner fitting body and the outer fitting body that can be connected to it is filled.

there make interior fitting body and outer fitting body together with the at least one housing extension an installation space is available, within it electronic or mechanical assemblies for identification, coding, data transmission to the mortise lock, data storage, Power supply and the like are easy to accommodate Of course can not be fully enumerated in their multitude.

So it should be possible biometric data such as Fingerprint, iris pictures or contactless keys, contact keys, Key cards, key fobs, active Use transponders (e.g. radio transmitters) and other identifiers.

Furthermore the access control device is compatible with all of them already installed door handle fittings and Rosettes, so that a already existing locking cylinder simply dismantled, the existing mortise lock against an electrically controllable one Mortise lock replaced and subsequently the fitting set according to the invention mounted can be done without any conversion measures the door would be required.

Of a particular advantage is the fact that the access control device - in contrast to locking cylinders - from different Door thickness is independent.

Only the connecting element between the inner fitting body and the outer fitting body is required at most an adjustment to the door thickness.

The The basic idea of the invention is therefore based on that for the accommodation a locking cylinder necessary installation space to use instead of the locking cylinder to arrange a fitting set that is designed so that at least one of the two fittings with a permanently connected housing extension protrudes into the already existing installation space of the locking cylinder.

On this way more is achieved Volume for accommodating components of the access control system and their wiring available stands. The simplified assembly results from the fact that the fitting set over the Housing extension in the existing cylinder perforation, which may also change in the door sign and / or in the door rosette is aligned in the correct position.

By omitting the lock cylinder, which is no longer necessary according to the invention and therefore no longer sits in the mortise lock, the wiring of the electrically controllable mortise lock can run through the cylinder perforation of the lock case, so that the mortise lock no longer requires any wiring that comes out of the side of the lock case must be brought out. The Omission of the lock cylinder therefore offers the advantage that the wiring can no longer interfere with the insertion of the mortise lock into the lock pocket of the door.

First after installing the mortise lock in the door, the connection cable is then from the original for the lock cylinder provided opening from the lock case pulled out and then e.g. to be connected to the interior fitting body.

Thereby, that both fitting body on the possibly existing door plate or door escutcheon set support, can Inner fitting body and Outer fitting body in the correct position be aligned and over the variable length Connection that practically forms the axial fastening of the two fitting bodies, cover a wide range of door thicknesses.

The This fitting set is therefore in connection with an electrical controllable mortise lock one important component for future omission of locking cylinders without the loss of security in terms of access authorization. moreover let yourself an assembly combined with such mortise practically all existing doors retrofit.

By the lock cylinder ceases to exist more volume to accommodate components of the access control device and their wiring available.

The Housing extension or the housing extensions can in the already existing cylinder perforation in the door plate / in the door rosette / in the door leaf be aligned in the correct position.

By the elimination of the locking cylinder the actuation takes place of the mortise lock only via the actuating handles, the inside and outside at the door are provided.

there makes the invention possible for the electrical controllability of the mortise lock, by namely about the Fitting set according to the invention the respective actuation of the mortise lock takes place as authorized access also via the actuation the mustache a locking cylinder would be done.

In order to let yourself also not compare the invention with a mortise lock, which has a so-called electronic double knob cylinder is operated.

in the With regard to an electronic double knob cylinder can namely at an access control device according to the present invention simple lever handle use find so that it no cumbersome key and / or knob rotation required.

The the entire electrical installation is within the hardware set with lock case including the Electronics for access control.

The lock bag in the door can be of the conventional for mortise locks Size and in case of retrofitting stay too. The length the required cable is so low that the mortise lock is no problem in the lock pocket used and in the event of a malfunction can be pulled out again.

By the short installation length there is no risk of damage to the cable Insert the mortise lock into the lock pocket of the door, so the danger of possible malfunctions is avoided.

Essential for the Invention is also the possibility Control different functions of a mortise lock electrically to be able to.

The end DE 44 07 244 C1 Known mortise lock is suitable to be used for the invention.

hereupon will be discussed in more detail using the description of the figures.

Provided nothing else is mentioned below, The following description always applies to all figures.

They show a set of fittings 1 as part of an access control device for a door 8th ,

The access control device includes the fitting set 1 also an electrically controllable mortise lock 7 ,

The electrically controllable mortise lock 7 is of conventional lock dimensions and fits with its lock case 17 in a corresponding lock pocket in the door 8th ,

The door handles 14 . 15 as operating handle and the inner door plate 9 or outside door sign 10 together form a door plate set. Instead of a door plate, a rosette can also be provided so that the inner rosette and the outer rosette form a door rosette set.

So far is the door 8th together with the door plate / door escutcheon and mortise lock 7 prepared with a cylinder perforation for receiving a locking cylinder 11 , which in particular in the 2 . 3 is shown.

Such a locking cylinder usually serves 11 a lock bit 12 inside the mortise lock 7 provided functional parts such as bolts or the like.

According to 3 it is a so-called profile cylinder 13 , which is formed by a circular cylindrical area for receiving the closing core and a web-like area attached to it along a surface line, which is on its lower end is also delimited by a circular section.

there the two circular sections of two parallel straight side flanks of the profile cylinder with each other connected so that the profile shown results.

Furthermore shows in particular 4 that the door 8th together with door plate / escutcheon and mortise lock 7 is also prepared for attaching an interior door handle 14 on the inside of the door and an outside door handle 15 on the outside of the door.

It is essential for the invention that in this constellation, which according to 2 previously with a locking cylinder 11 could be equipped, a fitting set 1 is provided according to this invention for installation in the pre-aligned cylinder perforation, which consists of an inner fitting body 2 and an outer fitting body that can be connected to it 3 is formed, of which at least one with a housing extension facing the door leaf 24 . 31 is provided.

For connecting the interior fitting body 2 and outer fitting body 3 serves the axial fastening 4 , which expediently from the side of the inner fitting body 2 through the cylinder perforation to the outer fitting body 3 runs.

How in particular 1 and 8th show, exists in such combinations of fittings 1 and electrically controllable mortise lock 7 the basic problem, the fitting connection cable 5 and the lock connection cable 6 in each case so long that the two cables at all before inserting the inner fitting body 2 in the door 8th can be connected.

The situation is similar when the outer fitting body 3 on the inside fitting body 2 to be connected.

As As a result of these two necessary excess cable lengths, there is a tangle of cables, so it is necessary is, if possible plenty of room for to accommodate the two cables.

There are also flexible pre-stamped fitting connection cables 5 corresponding 10 into consideration since the housing extension also gains due to the installation volume gaining properties of the invention 31 of the outer fitting body 3 to accommodate the corresponding fitting connection cable 5 can be used with.

In particular, the figures show a special case of the invention, in which both the inner fitting body 2 as well as the outer fitting body 3 each with a housing extension 24 . 31 are provided. Each housing extension protrudes from one side into the cylinder perforation.

Without limiting the invention, locking cylinders can 11 with a circular cross-section can be used.

Accordingly would be the Housing extension or the housing extensions accordingly circular configurable so that it fit into the circumscribed cylinder perforation.

However, profile cylinders are preferred and generally used 3 , so that the cross section of the respective housing extension in the cross-sectional circumference 30 (S. 13 ) of a corresponding profile cylinder 13 should fit in.

Generally speaking, the cross-sectional circumference of such a profile cylinder 13 formed from two circular sections connected by parallel lines.

Accordingly, the housing extension 31 from at least two inscribed circular cylindrical extensions 35 . 36 be formed (s. 12 . 13 ) that together so within the cross-sectional scope 30 of the profile cylinder 13 lie that with the housing extension 31 connected fitting body fits in the cylinder perforation 18 is aligned.

Of course, this also applies to a housing extension 31 from the cross section of the profile cylinder 13 and also for a housing extension 24 on the inside fitting body 2 ,

It also shows in particular 12 one way the axial attachment 4 between inner fitting body 2 and outer fitting body 3 variable in length.

For this purpose, a screw is used as a connecting element 29 provided, the screw length of the respective dimension X, which represents the door leaf thickness, is to be adjusted.

Additionally shows 12 that the - here - variable-length axial fastening 4 in the inner fitting body via a support plate 28 supported and by an anti-loosening device 27 is secured against loosening.

As you can easily understand, the screw thread is designed as a so-called right-hand thread, so that the loosening protection 27 effective in the opposite direction of rotation have to be.

It also shows 14 a further training in which in housing extension 31 of the outer fitting body 3 a screw thread 33 is arranged so that it merges in the screwing direction into a larger diameter space, the longitudinal extent of which is at least the length of the screw thread 33 equivalent.

This is here in a separate threaded sleeve 36 realized according to the individual figures of 14 in the outer fitting body 3 is to be assembled.

For this purpose is the threaded sleeve 36 at the end with a protective plate 37 provided, which in turn one the circular cylindrical region of the profile cylinder 13 facing nose 38 owns the associated part of the cylinder perforation 18 to cover up.

It is important to the cavity 32 , which is in the housing extension 31 of the outer fitting body 3 through the protective plate 37 to close.

This cavity 32 is however advantageous with regard to the passage of the fitting connection cable 5 only partially covered.

For this purpose shows in particular 14 , top right that the outer fitting body 3 with an insertion slot 34 is provided in the protective plate 37 can be inserted so far that at least the axial attachment 4 is protected against external attacks.

The protective plate 37 can be hardened to serve as a drilling protection plate.

In addition, the 9 to 11 Developments of the outer fitting body 3 ,

There is in a pocket 43 an outside fitting insert 40 provided, the at least one identification feature detection unit 42 contains.

These IME can be based on different principles. In particular, several IME 42 be provided.

In addition, an acoustic or optical signal generator is used 41 in the exterior fitting insert 40 the purpose of indicating to the person requesting access whether the identification carrier 44 the IME 42 has acted accordingly.

The acoustic or optical signal generator 41 can consist of a tone generator, for example an energy-saving buzzer or at least one energy-saving LED.

Furthermore shows 10 that in the outer fitting body 3 a drill protection insert 39 can be provided, preferably by an outer fitting insert 40 is covered.

7 shows different identification feature carriers 44 ,

The IMT 44 is with the IME 42 so matched that either key cards 44a Keychain 44b or cylinder key 44c each with a transponder or contact-bound readable keys 44f can be read as well as radio transmitters 44d or fingerprint sensors 44e ,

In addition, this shows in particular 16 that the cavity in the inner fitting body 2 , which is used to accommodate the components of the access control device, up to the housing extension 24 of the inner fitting body 2 extends.

How 16 shows at least one power supply (EV), an identification feature evaluation unit (IMAE) and a control unit (AE) can be accommodated here.

Is now over the IME of the outer fitting body 3 the information stored on the IMT is read out and the IMAE of the interior fitting body via the ÜL 2 transmitted, so if access authorization is also recognized, a coded signal is sent to the assigned IKE in the mortise lock via the optionally provided IKE 7 transmitted so that a correspondingly provided ZSG is activated.

By coding the data transmission between the two IKE units in the interior fitting body 2 and mortise lock 7 there is a risk of manipulation after the hardware set has been removed by force 1 significantly reduced, since only appropriately coded signals are expected from the lock-side IKE to activate the ZSG.

In addition to this shows in particular 12 that the inner fitting body 2 through a lid 25 is covered, the unauthorized access to the power supply (EV), the IMAE, the control unit (AE) and the axial fastening 4 prevented.

This is accordingly 16 the inner fitting body 2 provided with a lid release unit (DFE) that holds the lid 25 only releases if a predetermined key has previously been recognized by the IMAE as authorized to access.

Alternatively or additionally, for example, a small furniture cylinder can also be provided around the cover 25 to be able to open after key operation.

In addition to this shows 16 that on the lid 25 also solar cells (SZL) can be arranged, which charge the EV via a charging unit.

Such solar cells are expediently on the surface of the inner fitting body 2 provided to charge the EV via the SZL. Another arrangement of solar cells 46 shows 4 at one point the greatest possible incidence of light.

Also sits in the interior fitting body 2 an external communication unit (EKE) via which a network connection is possible without contact. The EKE serves the purpose alone or in connection with the network connection, data in connection with the programming of access authorizations, movement data about permitted and prevented access as well as data for the condition monitoring of the hardware set 1 connected lock to transmit.

Like especially that 1 and 8th show, it is essential the inner fitting body 2 to be equipped with the appropriate electrical / electronic components, so that a transmission line ÜL from the inner fitting body 2 to the electrically controllable lock is provided to ultimately operate it.

Here is a lock connection cable equipped with a predetermined plug 6 or a flexible printed circuit board expedient.

Similarly, the transmission line ÜL between the outer fitting body 3 and the inner fitting body 2 fitting connection cable equipped as a plug 5 or be designed as a flexible printed circuit board.

In this respect, the use of plastic and / or die casting for the inner fitting body is of importance 2 and the outer fitting body 3 ,

From this there is the advantage of inexpensive mass production, whereby under consideration of given security against break-in through the coded signal transmission IKE (interior fitting body) -ÜL IKE (mortise lock) none the fitting body an outstanding one Must offer security against violent breakup.

In addition, the figures show that the interior fitting body 2 and / or outer fitting body 3 with their the door 8th facing surfaces flush on a door escutcheon or a door plate with cylinder perforations 18 are attachable.

The interaction between the fitting set according to the invention 1 and the mortise lock 7 can best be determined using 6 explain by way of example.

The mortise lock 7 points according to 4 an inner nut 22 and an outer nut 23 on.

The inner nut 22 and the outer nut 23 together form a common lock nut, each of which part nut with an associated handle 14 . 15 is rotatably connected.

The mortise lock can be inserted through the two partial nuts 7 perform different functions for each of the two sides of the door.

It is provided here via a mechanical clutch mechanism 47 the outer door handle 15 only to activate the lock latch 19 allow if the associated electromagnet 48 is energized.

Though this results in a relatively large power consumption because the Release via must be maintained for several seconds.

But in the case of access authorization, the lock latch can be withdrawn in any case 19 and lock bolt 21 by operating the outside handle 15 activate.

Here is an example of an auxiliary trap 20 (S. 5 ) extending the lock bolt 21 controlled.

hereupon however, should not be closer be considered, as this is only one possible embodiment for the Application of the fitting set according to the invention represents.

In in any case, however, such a mortise lock has one relatively high power consumption.

To this purpose can be complementary a generator unit GE can also be provided in the mortise lock, with which by pressing of the door handle outside and / or so much electrical energy is generated inside that the state of charge of an assigned battery is retained.

In this respect, it should be expressly mentioned that the electromagnet 48 according to 6 is functionally identical with the access control actuator (ZSG) according to 16 ,

As an alternative to such an electromagnet 48 an appropriate electric motor could also be used.

Furthermore shows 16 also a lock monitor (VÜ), via which the condition is properly locked when the door is closed can be.

Mutual communication between the IKE units in the mortise lock 7 and in the interior fitting body 2 can also be designed so that an exchange of the mortise lock or another component would be recognized.

This measure serves to thwart attempts at manipulation via the ÜL.

In particular the figures also represent the following facts:

1 The tangle of cabling is clearly visible, which is required to be able to connect the fitting set with the lock and to be able to use the fitting set for larger door thicknesses.

3 The 2 and 3 illustrate the space required by the locking cylinder 11 - in this case from the profile cylinder 13 - is used.

4 The lock bolt moved into the door frame is particularly recognizable 21 , the lock latch 19 as well as the connection between the door handle and the lock. The fitting set according to the invention is partially hidden by the two door handles. The cross-hatching of a partial surface of the inner fitting body 2 is intended to show an assembly with solar cells as an exemplary embodiment.

5 lock latch 19 and auxiliary trap 20 of the lock are sticking out, the bolt is in the withdrawn release state. On the outer fitting body 3 can be seen: the round insert with the identification feature detection unit and above it the two light-emitting diodes as signal transmitters 41 to report back to the user.

6 The left LED of the signal generator 41 should signal to the user that the lock is released for use.

8th This illustration was repeated to underline the importance of the available installation space for the accommodation of the cables.

10 Because the screw thread 33 for screwing directly into the outer fitting body 2 sits, an investment casting or die casting material must be assumed in this embodiment. An interchangeable insert with antenna as IME and light-emitting diode as SG and connected cable is installed in the outer fitting body; a hatched plate is placed under the insert to protect access to the cable to the lock and the screw connection of the fitting set.

11 It can be seen that the bag 43 has a narrower bulge for use upwards, for example to accommodate the light-emitting diode.

12 In this embodiment it is assumed that both fitting bodies are made of plastic. In order to still offer an acceptable level of security, the outer fitting body 2 a drilling protection plate with attached - eg welded - threaded sleeve inserted.

13 This representation is intended to underline that even with a multi-part outer fitting body, a fit-like fit of the housing extension in the contour of the profile cylinder cross section can be achieved.

14 The protective plate 37 has a semicircular nose 38 , which is intended to protect the cavity in the housing extension. The two neighboring rectangles with dashed lines are intended to symbolize light-emitting diodes.

15 The lid 25 is inserted and then engages in a locking device DFE, not shown. Opening the lid 25 should only be allowed after using a special key. This is dash-dotted on the lid 25 Drawn rounded rectangle is intended to indicate the possibility that the lid 25 can also be provided with solar cells.

The C-shaped support plate in the inner fitting 2 is proposed in order to be able to transmit a higher axial force via the screw connection when trying the outer fitting body 3 demolish. There is a screw lock washer between the support plate and the head of the screw.

16 The abbreviations and abbreviations are explained in the table above. In the simplest case, the access control system according to this invention only has the fitting set with the components IME, ÜL, IMAE, AE and EV in order to control the electromagnet (ZSG) in the lock after successful recognition of the authorized key (IMT).
