One edge of its side-arms has a unilaterally-acting fixed stop-piece; the contrary fixed stop-pieces are positioned at the join with the hollow profiles. A sloping lead-in part (17,18) belonging to each of the fixed stop-pieces (15,16) is positioned at the other edge (13) of the side arms (11) and on the opposite side of the join (6). The sloping lead is positioned at a slanting transition (14) between the side and middle (10) arm.

Description

The invention relates to a connector for Hollow profiles, especially spacers from Insulating glass panes, with the features in the preamble of Main claim.

Such a connector is from EP-A-0 330 906 known. The connector has a U-shaped Cross section with a central bar and two on it adjacent side bridges. At the transition between Mittelund Sidewalls are stops and bevels separated and spaced apart. The Stops act on both sides and distance the Hollow profiles forming a joint on the Junction through which a sealant enters from outside the hollow profiles can be injected. The In cross section, bevels have a triangular shape and are lower than that at their highest point adjacent stop. The ramp bevels are used for Twist and orientation of the connector in the correspondingly stable hollow profiles.

Another connector is from DE-U-94 11 067 known. It has an essentially U-shaped Cross section with a central web and two side webs. At the free edge of the side bars, each has a fixed one-way stop, the stops counteract and in the area of Connection point of the hollow profiles axially offset are arranged to each other. These attacks are as thin-walled straight projections of the side webs are formed and can be shown with feather noses in the middle Interact with the area of the center bar. These feather noses are set back from the junction and serve as retention elements, their unintended Pulling out the connector also the hollow profiles should prevent. In a construction variant, the A single, wider fixed stop in the middle of the central web be arranged opposite such a spring nose. This script also shows in another Embodiment a connector with two am Center bar and with a lateral distance from the side bars arranged rigid stops in the form of both sides acting pimples.

The known connectors are particularly suitable for relatively thick-walled hollow profiles that have a high Have dimensional stability. In the course of profile development there there are now very thin-walled profiles including stainless steel. These profiles do not have such a high dimensional stability and can cut to length by cutting or sawing deform. With such profiles, it is difficult to Insert the connector to hit the center and the bring the designated stop to the system. Because of the small profile wall thickness should only stop have a relatively low height.

It is therefore an object of the present invention to To show connectors that are also for thin-walled and dimensionally stable hollow profiles is suitable.

The invention solves this problem with the features in the main claim.
The connector according to the invention is preferably equipped with fixed stops, which are arranged at the transition between the central web and side webs of the connector. As a result, the run-up bevels act in the corner areas of the hollow profile, where they find sufficient form resistance and sufficient support due to the bending deformation of the hollow profile. The corner areas of the hollow profiles are usually the least deformed.

The stops are on the back with bevels equipped on which the cross section of the connector adapted hollow profile can slide. The ramp pull the pushed-on hollow profile against the opposite web edge. Here, on the one hand Support the hollow profile and is guided reliably. The Web edge can do this at least in the area of the connection point have a smooth continuous edge. Here can alternatively also additional fixed stops be available on which the hollow profile comes to rest.

Due to the ramp and the tension between Hollow profile and connectors come the stops reliably in contact with the front wall of the slid on Hollow profile. Even with heavily deformed hollow profiles reliable when inserting the Find the connector in the middle. The profiles can butt the connection point closely.

It is for the stops or their bevels particularly advantageous if they have an outwardly convex have a domed shape. Due to their location and training they act exactly in the corner area of the hollow profiles and thereby both the aforementioned stop and Improve centering function, as does the hollow profile stabilize yourself.

The connector according to the invention can be elastic Have sealing body that for a safe, simple and inexpensive sealing at the connection or Butt joint of the hollow profiles ensures. The sealing body is especially cheaper than e.g. from EP-A-0 133 655 and EP-A-0 330 906 known seal, in which during assembly of the connector in the Hollow profiles a sealing compound made of butyl or the like injected into an internal free space becomes. In particular, the sealing body enables Reliable seal against fine dust that is made up the granulated in the spacer frame Desiccants can develop.

The elastic sealing body has the further advantage that it is easy to handle. Due to its excess, it becomes the assembly pressed together and lies with pressure on the sealing point of the hollow profiles to be sealed. This ensures an improved sealing effect.

The connector can have several in its wall Have openings through which the elastic sealing body when pressed together, step out and seal can lay against the hollow profile wall. For one, it can the recesses on those in the corner area Stops and sliding slopes. On the other hand, you can but also recesses for on the opposite edge of the web a lateral passage of the sealing body is available his.

To fix and guide the sealing body, it is advantageous if the connector has a suitable cavity has, in which the shaped body optionally with Shape adjustment can be arranged. Here he lets himself in a simple way, e.g. through an adhesive connection Fasten.

It is to improve the compression and sealing effect advantageous if the connector has a projection the wall opposite the cavity opening has. The projection bulges the sealing body in the area the connection point reinforced by the cavity opening outward.

In the subclaims are further advantageous Embodiments of the invention specified.

Figures 1 to 11 show a connector (1) in the form of a straight connector for hollow profiles (2,3) from Spacers for insulating glass panes is provided. Figures 5 to 7 show the connector (1) in connection with such hollow profiles (2,3). Alternatively, it can also around other hollow profiles, e.g. Sprouts for Act insulating glass panes.

The one formed by the hollow profiles (2, 3) shown Spacers are used to distance two Individual panes of an insulating glass pane (not ) Shown. The hollow profiles (2, 3) shown are preferably particularly thin-walled and consist of Stainless steel. You have compared to the previously used thick-walled hollow profiles made of light metal, in particular Aluminum or aluminum alloys, clearly reduced thermal conductivity and are for higher quality Thermal protection glazing particularly suitable. such Hollow profiles (2,3) have e.g. a wall thickness of approx. 0.2 mm.

The hollow profiles (2,3) have shown in the Embodiment a substantially rectangular Cross-sectional shape. In the corner area (5) (see Figure 10) between the one pointing outwards on the spacer frame Roof area (4) and the side walls can be chamfered or rounding off. The opposite Profile floor is on the inside of the frame (7) of the Spacer frame and points to the window interior. Between the bottom and the side walls of the hollow profiles (2,3) there may be sharper corners. If necessary, the side walls can be above the floor continue also into longitudinal webs. The shown cross-sectional shape of the hollow profiles (2,3) however vary in any way and other than shown to be trained.

The connector (1) is in its cross-sectional shape adapted the shape of the hollow profiles (2,3). He has in Embodiment shown in cross section a U-shape with a central web (10) and two perpendicular to it protruding side webs (11). The central web (10) points to the roof area (4). Between the central web (10) and the Side bars (11) can be an oblique or round transition (14) be present. Deviating from the shown The connector (1) can also be an exemplary embodiment have box-shaped closed cross-section. In Adaptation to the hollow profile shape can change its shape also vary in other ways.

The connector (1) shown preferably consists of Metal. But it can also be made of plastic or any other suitable materials as well Composites exist. In the shown The embodiment is made of stamped and bent parts Made of sheet steel. It preferably consists of a Steel strip that is tempered after stamping and bending and is galvanically treated.

The connector (1) has at the connection point or Joint (6), which is also preferably the transverse one Center line of the connector (1) forms one Center stop. The center stop consists at least of two stops (17, 18) on which at least the end wall of the first pushed-on hollow profile (2,3). 1 to 4 fixed stops can also be used (15:16) be present. Through the center stop half of the connector (1) in each of the two Hollow profiles (2,3). It enables a tight Butting of the hollow profiles (2,3) on the Junction (6) and largely prevents Formation of joints at this point. This improves on the one hand the optical appearance of the spacer and on the other hand prevents the inside granulated drying agent at the connection point (6) emerges and gets into the window interior.

As shown in Figures 3, 4, 9 and 10, the stops (17,18) at the aforementioned oblique transition (14) between Middle and side web (10,11) arranged. The attacks (17,18) point obliquely outwards and have one round convex cross-sectional shape curved outwards (25). In the exemplary embodiment shown, they are punched out and chiselled.

The stops (17, 18) are directed towards each other and one-way preferably fixed stops educated. They point in opposite directions, each stop (17, 18) only on a hollow profile (2, 3) acts. As illustrated in FIG. 11, the hollow profile lies (2) on the stop (17) and the hollow profile (3) on the stop (18). The stops (17, 18) are on the front and Connection point (6) facing end transverse to Straight cut longitudinal connector axis and form thereby a stop edge (19). The attacks (17,18) are axially to each other in the area of the connection point (6) staggered and lie against each other Junction (6) opposite. You can order one set back a small distance from the connection point (6) his.

The stops (17, 18) each have on their back a ramp (24) from the top of the Transition (14) to the stop edge (19) and Connection point (6) rises wedge-shaped. Before Stop edges (19) of the stops (17, 18) is located each a punched-out recess (21). The recess (21) facilitates the chiselling and is to form a straight stop edge (19) advantageous.

The curvatures (25) of the stops (17, 18) or their Run-up slopes (24) can be designed as small humps be narrower than the transition (14). Figure 3 and 4 show such training. In another Variant, as shown in Figures 9 and 10, are the bulges (25) larger and go with their side Flanks in the central web (10) or the adjacent Side bridge (11) over.

The additional fixed stops (15, 16) are on an edge (12) of the side webs (11) arranged. This is preferably the one towards the inside of the frame (7) pointing lower web edge. The fixed stops (15, 16) are effective only in one direction, these directions of action are opposite. The fixed stops (15, 16) are in Area of the connection point (6) axially to each other staggered and lie against each other Junction (6) opposite. One right Fixed stop (15) acts with the hollow profile (2) and other fixed stop (16) together with the hollow profile (3).

As shown in Figure 2, the fixed stops (15, 16) preferably the shape of substantially triangular Stop lugs and have at the connection point (6) facing the front a straight stop edge (19), which runs essentially transversely to the longitudinal axis of the connector. The stop edge (19) can be cut in a small way leak. The stop lugs have on the back (15, 16) an inclined flank rising from the web edge (12) (20), on the back of each Slid on hollow profile (2,3). The shape can be according to DE-U-94 11 067.

In the embodiment shown, the stop lugs are (15,16) from the lower web edge (12) and are in Extension of the side bars (11). Alternatively, the Fixed stops (15, 16) also diagonally or laterally be issued and thus over the side surface of the Project the webs (11) to the side.

At the other edge area (13) of the side webs (11) are Stops (17, 18) arranged. Above the fixed stop (15) is the stop (17) and above the fixed stop (16) the other stop (18). As Figure 2 illustrates, the fixed stops (15, 16) and theirs are the same Side web (11) assigned stops (17, 18) each the connection point (6) arranged opposite. The Fixed stops (15, 16) lie on one side of the Junction (6) and the stops (17, 18) on the opposite side.

As shown in Figures 1 and 2, the stop edges (19) the one located on the same side web (11) Fixed stops (15, 16) and stops (17, 18) in opposite directions. The stop edges (19) can, as shown in the embodiment, compared to Junction (6) or center line somewhat axially be set back. Alternatively, you can are also at the same level.

In their stop function, the rectified act Fixed stops (15, 16) and stops (17, 18) and their Sloping slopes (24) together. This means that the Fixed stop (15) with the one on the other side web (11) located stop (18) cooperates and the Fixed stop (16) with the also diagonally opposite stop (17). This in their Stop function interacting stops (15, 18) and (16, 17) lie axially with their stop edges (19) at the same height. The pushed-on hollow profiles (2,3) thereby hitting two diagonally across the Profile cross-section on opposite end wall corners.

As illustrated in the left-hand illustration in FIG first the hollow profile (2) in the direction (8) on the Plug connector (1) pushed on. It slides in outer corner area (5) on the ramp (24) of the stop (17) and their oblique flank. At the the hollow profile slides diagonally opposite the corner (2) on the rear flank (20) of the fixed stop (16) (not visible). In the field of Connection point or center line (6) beats the profile (2) in the floor area at the fixed stop (15) and in the diagonal opposite corner area (5) at the stop (18).

The previous sliding of the hollow profile (2) on the Run-up slope (24) of the stop (17) causes that Hollow profile (2) raised and with the floor against the lower web edge (12) is pressed. That’s why Hollow profile end wall securely in contact with the Stop edges (19) of the stop (18) and the Fixed stop (15).

As shown in Figure 2, the fixed stops (15, 16) only a slight amount beyond the assigned Web edges (12) to the outside. This supernatant is in about as large as the profile wall thickness and is in embodiment shown about 0.2 mm. The increase in Sloping slopes can be much larger. In the shown embodiment it is e.g. at the crown and at the stop edge (19) approx. 0.5 to 1 mm.

The second hollow profile then pushed on (3) beats on the face of the first hollow profile (2) or on the associated stops (16, 17) of the connector (1). If the stops (15,16) and (17,18) opposite the connection point (6) is axially set back are, the stop is made on the previously pushed Hollow section (2).

FIGS. 5 and 6 show a variant of the connector (1) from Figure 1 to 4. The formation and arrangement of Stops (17, 18) and their run-up slopes (24) is in both embodiments the same. In addition, the hereby achieved stabilization effect Corner area (5) of the hollow profiles (2,3) on the one hand and the sure hitting the stop edges (19) of the On the other hand, stops (17, 18) were given and reached. In Figures 5 and 6 are in variation of the above Embodiment omitted the fixed stops (15, 16). Instead, the lower web edge (12) has at least one in the area of the connection point (6) straight and continuous edge (26). This edge (26) supports itself the connector (1) on the bottom (7) of the hollow profiles (2, 3) from. Due to the straight continuous edge it is Support function particularly good. At the transition (14) located stops (17, 18) with their run-on slopes (24), the hollow profiles (2, 3) are particularly good at this stabilize and align.

For a secure hold of the connector (1) in the pushed on hollow profiles (2,3) provide one or more Retaining elements (22, 23), which are designed differently could be. In the embodiment shown, the lower web edges (12) of the side webs (11) each punched out and bent downwards and laterally Spring lugs (23) arranged. These can be done on their own already suffice. Additionally or alternatively, on several to the center outside of the central web (10) Openings (22) exist in the caulking on Intervene roof area (4) of the hollow profiles (2,3) and one form a positive connection. This training corresponds to e.g. DE-A-43 35 039. Alternatively or In addition, spring noses can be issued on Middle web (10) should be available. The connector (1) can be closed or open at the front. He can otherwise have any other shape and training than in the embodiment shown.

FIGS. 7 to 11 show a further variant of the Connector (1). In the embodiment shown the connector (1) also essentially one U-shaped cross section. Its wall consists of one Center bar (10) and two vertical or sloping ones Side bars (11). At the end faces (31) is the Center web (10) angled obliquely and forms in this Area also a substantially closed Wall. The webs (10, 11) enclose one another Cavity, (32) facing one side with its Cavity opening is open.

A sealing body (28) is arranged in the cavity (32), e.g. is designed as a rectangular pillow and by an adhesive connection or in any other way suitably on the inside of the central web (10) is fixed. The sealing body (28) can match the shape of the Be adapted cavity (32) and this completely to complete. The sealing body (28) consists of a elastic material, e.g. a plastic foam. The Sealing body (28) is so large that it through the Cavity opening (32) protrudes a bit outwards and thus over the contour of the connector (1) or over the protrudes lower edge of the side webs (11).

The sealing body (28) is at least in the area the connection point (6) shown in the Connector preferably with its center in Longitudinal direction is identical. Like Figures 9 and 10 illustrate, the sealing body (28), which is initially board over the side webs (11) when installing the Connector in the hollow profiles (2,3) compressed and lies with pressure in the area of the cavity opening (32) on the inner wall of the hollow profiles (2,3). He engages over the connection point (6) and seals it.

There is a granulated in the spacer frame Desiccant (30) that matches the interior of the Insulating glass pane over a perforation in the profiles communicates. Through the closed end faces (31) and additionally through the sealing cushion (28) This granulate (30) emerges at the connection point (6) prevented.

As shown in Figures 9 and 10, the connector (1) so mounted in the hollow profiles (2,3) that be Middle web (10) to the outer roof area (4) of the Has hollow profiles (2,3). The cavity opening (32) has towards the bottom area (7) of the hollow profiles (2, 3). The The floor area (7) is turned towards the interior of the window.

For centering the connector (1) at the Assembly are at least the stops described above (17,18) and any other stops in any suitable version available. The one shown in Figure 10 right stop (17) works with his Connection point (6) facing front or Stop edge (19) as a stop for that in the drawing plane hollow profile (2) pushed on from behind and forms with the back of the sliding slope (24) for the other front, sectioned hollow profile (3). The left stop (18) is designed accordingly and twisted arranged. He acts as a stop for that Hollow profile (3) and as a sliding slope (24) for the Hollow section (2).

The connector (1) has in the area on the central web (10) the connection point (6) towards the cavity (32) directed projection (29) which e.g. as one plate-shaped expression is formed. This Projection (29) bulges the sealing body (28) on the Connection point (6) through the cavity opening (32) outwards. Figure 8 shows this effect. By this curvature becomes the sealing body (28) on the Connection point (6) additionally during assembly condenses and develops one at this critical point increased contact pressure and sealing effect.

As Figure 8 further illustrates, the side bars have (11) in the area of the connection point (6) at its free Edge (12) a recessed recess (27). By this recess (27) can be used during assembly of the compressed sealing body (28) penetrate and in sealing Contact with the side walls of the hollow profiles (2,3) reach. Figure 10 also shows this effect.

The sealing body (28) can also in the area of Stops (17, 18) through the recesses or free cuts (21) step out and these openings additionally seal tightly or in sealing contact with the Kick hollow profiles (2,3).

The connector (1) can also one or more Have resilient or rubbing retaining elements (23). The embodiment shown is cut-out and laterally curved retention lugs (23), which are each angled in the entry direction and when retracting in the hollow profiles (2,3) dig. In the area of the retaining lugs (23) recesses or free cuts (21) are also present be through which the sealing body (28) during assembly attacks.

In addition, the connector (1) can also be other Have attachment options. In the shown Embodiment he has several of the middle web (10) above described caulking openings (22) with suitable Shape, through which wall caulking after assembly in the roof area (4) of the hollow profiles (2, 3) with a positive fit intervention. The wall caulking is done from the outside attached stamp achieved the hollow profile wall through the caulking openings (22) into the cavity (32) and press the sealing body (28). The sealing body (28) can essentially all openings on the connector (1) seal tightly during assembly.

Variations of the shown embodiments are in possible in different ways. For one, they can Fixed stops (15, 16) a different shape, location and Have alignment. Likewise, the wedge-shaped Run-up slopes (24) or the stops (17, 18) on the Plug connector (1) can be formed or attached. in the The area of the central web (10) can have further stops be present, e.g. existing in this area too Align the wall deformations of the hollow profiles (2,3) and correct. For this purpose, for example, are also close to Connection point (6) arranged spring lugs suitable. In addition, the connector (1) can be closed Have cross-section with two central webs, whereby accordingly also on the second central web spring noses, Stops and the like can be arranged.

The connector (1) can also have several cavities (32) have, if necessary, all with a corresponding designed sealing body (28) at least partially filled are. Furthermore, the cross-sectional design of the Any connector (1). Furthermore, an additional Sealing body also in the area of the projection (29) be arranged on the outside. The sealing body (28) can have a shortened form, which is essentially the Junction (6) and a certain bilateral Security area covered. The sealing body (28) leaves educate yourself with lateral oversize so that he already when fastening in the connector (1) by the Recesses (27.21) occurs. However, it can also be used as in the embodiment shown exactly between the Side webs (11) to be fitted or even narrower. The training and arrangement of the are also variable Stops (17, 18) and the retaining elements (23, 22). The Connector (1) could also on the end faces (31) be open.
