Description

The The invention relates to a three-piece door fitting for mounting on a Door panel, in particular a corner fitting for a glass door.

Two-part door fittings, especially for glass doors are known from the prior art. The typical structure of such a fitting according to the prior art shows the 1 , In 1 Two variants of a mounted door fitting according to the prior art are shown. The left variant shows a mounting on a thick door leaf 2 and the strength s, whereas the right-hand representation is an assembly on a thin door leaf 2 with the strength s' shows. In both installation variants, the fitting consists of the same support plates 3 and the same counter-plates 4 together. As in 1 The different door leaf thicknesses s and s' can be clearly seen through different thicknesses of distance 5 balanced.

This known method for balancing the different door leaf thicknesses with different thicknesses of distance 5 is disadvantageous in many ways: The installer of the fitting must here the appropriate distance 5 Select or different distances 5 stack each other and then mount the fitting so that these spacer layers 5 do not slip. In addition to this assembly unfriendliness also results in aesthetic terms a disadvantage when using decorative caps on the support plate 3 or the counter-plate 4 , Due to the different distances between the door leaf and the fitting these Dekorkappen are different close to the door leaf, creating inconsistent gap widths. Especially when using glass doors and glass partitions with different glass thicknesses such deviations in the columns on the decor caps are particularly noticeable.

It object of the present invention to provide a door fitting, which both cost-effective can be produced as well as easy to assemble. Further It is an object of the invention to provide a process for effective production of the door fitting provide.

The Task is solved by the features of the claims 1 and 14. The subclaims have advantageous refinements of the invention the subject.

In order to the invention is solved through a door fitting for mounting on a door leaf, comprising a support bridge, which for connecting the door fitting with a door closer / opener shaft or a hinge or a lock is formed, a first clamping plate, which is designed for mounting on one side of the door leaf, and a second clamping plate, which for mounting on the other side of the door leaf opposite is formed to the first clamping plate.

Consequently You can advantageously through both clamping plates and the intervening located carrier bridge a Set screw connection. Additionally or instead, you can use the two clamping plates through a hole in the door leaf screw.

Further is advantageously provided that the support bridge a mountable in the support bridge Insert for connecting the door fitting with a door closer / opener shaft or a hinge or a lock. By use This modular insert makes it possible to have uniform girder bridges various applications adapt. Under door closer / opener shaft Here is the output shaft of both a door closer, a door opener as also a combination of door closer and opener too understand.

Of Furthermore, it is advantageously provided that the support bridge a first contact surface in a distance from a second abutment surface, wherein the first contact surface is adapted to abut the first contact plate, and the second contact surface is adapted to abut the second contact plate. The Beam bridge points So a certain thickness or a certain distance between the two contact surfaces on.

In Advantageous embodiment, this distance corresponds to a door leaf thickness of the Door panel, to which the door fitting according to the invention is mounted so that the girder bridge at both Pages of the door leaf flush with the door leaf concludes. In an advantageous embodiment, the first contact surface and the second contact surface the utmost Surfaces of the Beam bridge, so that the biggest thickness the carrier bridge exactly the door leaf thickness corresponds. This allows each of the two clamping plates flush with the door leaf and resting on the support bridge. By this advantageous adaptation of the support bridge to the door leaf thickness is the use of awkward avoided to be mounted distance layers. Since the two contact surfaces of the Support bridge flush with the door leaf run, can the two clamping plates are screwed against each other in parallel.

alternative to the exact tuning of the carrier bridge the door leaf, is advantageously provided that the distance between the first contact surface and the second contact surface is adjustable. This means, that the distance by the fitter when mounting the fitting on the door leaf adjusted the corresponding door leaf thickness becomes. This has the advantage that uniform girder bridges for different door leaf thicknesses produced can be.

In Advantageous embodiment of the adjustable support bridge is provided that the first contact surface and the second contact surface be in operative connection with a gear, so that the first contact surface and the second contact surface can be adjusted synchronously by turning the gear. This means so that advantageously between the two contact surfaces in the girder bridge Gear sits, with each of the contact surfaces of a rack inside extends to the gear. Characterized in that the rack of the first contact surface on the Gear opposite the rack of the second contact surface sits, Kings nen by turning of the gear, the two contact surfaces simultaneously outward or be moved inward at the same time.

alternative To this adjustment by means of gear and racks is advantageously provided that the first contact surface and the second contact surface on a rotatable disc with different widths are arranged, so that the first contact surface and the second contact surface can be adjusted synchronously by rotating the disk. The two contact surfaces So are on this disc and by turning the disc adjusted the distance.

there is advantageously provided that this disc both point-symmetrical is formed to its center as well as several opposite surfaces or has pages. By this symmetrical polygonal embodiment of the Slice, the distance can be set to fixed predefined values become.

alternative to the polygonal configuration of the disc, it is advantageous also possible, the To make a disc as an involute. This increases a circumferential distance from the center of the disc to the outer edge of the disc their extent steadily, creating a continuous adjustment of the Distance between the two contact surfaces possible is.

Advantageous manufacturing process for the Trä The bridges are both plastic injection molding and cast steel or aluminum chill casting. Advantageously, both the carrier bridges and the clamping plates can fulfill decorative functions and represent crucial surfaces for the design of the door fitting.

In Advantageous application is the door fitting according to the invention for use with a glass door educated.

The The invention further comprises a manufacturing method for the clamping plates of the door fitting according to the invention with the step: injection molding an intermediate layer on the clamping plate. So it will be advantageous on the first clamping plate and / or the second clamping plate on their the door leaf and the carrier bridge facing Side opposite door leaf and girder bridge softer Interlayer by injection molding applied. The material used here is advantageously similar the plastics of a high-pressure seal. As the door fitting according to the invention executed in three parts is and advantageously the attitude to the different Door leaf thicknesses over the Carrier bridge takes place, can the clamps independently uniform from the door leaf thickness be made. It is particularly easy to install when the intermediate layer is already on the clamping plates, so that the items for the assembly is reduced to a minimum.

The following is based on the 2 to 5 the first embodiment of the door fitting 1 shown.

The 2 to 4 show different installation conditions of the door fitting 1 , This door fitting 1 consists of a girder bridge 6 between a first clamping plate 7 and a second clamping plate 8th ,

To illustrate the function of the door fitting 1 is in the 2 and 3 a door leaf 2 shown. This door leaf 2 is not part of the door fitting according to the invention 1 , but to explain the assembly of advantage. Like in the 2 drawn, this door leaf extends 2 in a plane 2c and has a first page 2a as well as a second page 2 B ,

Other components of the door fitting 1 are in accordance with the 2 to 4 a first screw connection 9 in a first through hole 10 of the door leaf 2 and a second screw 11 in a second through hole 12a in the girder bridge 6 , Furthermore, in the door leaf 2 a corner 16 arched recessed, so that the support bridge 6 with a rounding 15 exactly in the recessed corner 16 fits.

The girder bridge 6 extends essentially in the same plane 2c like the door leaf 2 and can therefore frontally to the door leaf 2 in the recessed corner 16 be fitted. On the first page 2a of the door leaf 2 becomes the first clamping plate 7 and on the second page 2 B of the door leaf 2 the second clamping plate 8th assembled. The two clamping plates 7 . 8th overlap both a part of the door leaf 2 as well as the entire girder bridge 6 , Around the girder bridge 6 firmly with the door leaf 2 connect through the first through hole 10 in alignment with corresponding through holes in the clamping plates 7 and 8th the first screw connection 9 used. Furthermore, the second gland 11 through aligned holes in the two clamping plates 7 and 8th and through the second through hole 12a in the girder bridge 6 used. This allows the two clamping plates 7 . 8th be screwed parallel to each other. A third through hole 12b in the girder bridge 6 allows a third screw not shown.

The girder bridge 6 This embodiment is for connecting the door leaf 2 formed on a bottom door closer shaft. For this purpose, the support bridge 6 the recess 14 on. In this recess 14 can be an insert 13 be used. This insert 13 turn, the cut represents to the bottom door closer dar.

Further shows 5 that on the inner side of the clamping plates 7 . 8th an intermediate layer 17 is applied. This intermediate layer 17 was injection molded onto the insides of the clamping plates 7 . 8th applied and allow a soft non-destructive concern of the clamping plates 7 . 8th , Especially with a door leaf 2 of glass.

Furthermore, in 5 good to see that a distance d between a first bearing surface 18 the first clamping plate 7 at the girder bridge 6 and a second contact surface 19 the second clamping plate 8th at the girder bridge 6 exactly corresponds to the door leaf thickness s. By using such carrier bridges 6 , adapted to the door leaf thickness s, it is possible that uniform clamping plates 7 . 8th with uniformly thick intermediate layers 17 can be used.

Based on 6 to 8th Below is the second Ausführüngsbeispiel the door fitting 1 explained.

6 shows two variants of the mounted door fitting 1 according to the second embodiment on a thick door leaf 2 with thickness s and a thin door leaf with strength s'. In the second embodiment, the same or functionally identical components are denoted by the same reference numerals as in the first embodiment.

In the door fitting 1 according to the second embodiment, the fitter selects the carrier bridge 6 no longer according to the used door leaf thickness s, but the distance d between the first contact surface 18 and the second contact surface 19 the girder bridge 6 is adjustable here in the second embodiment by the installer. This also allows for the door fitting 1 according to the second embodiment, regardless of the door leaf thickness s uniform clamping plates 7 . 8th with uniform intermediate layer thicknesses 17 be used.

To a parallel concern of the clamping plates 7 . 8th ensure even with the smallest adjustable door leaf thickness s, the clamping plates have 7 . 8th according to the second embodiment mutually extending Endanschlagsflächen 20 on.

The representation in 6 shows the door leaf 2 or the door fitting 1 from above. The two arrows marked with X in 6 interpret the line of sight for the views of 7 and 8th at.

The 7 and 8th show two different adjustment mechanisms for the distance d of the support bridge 6 according to the second embodiment.

The first variant of the adjustment mechanism in 7 includes a tool intervention 22 in the middle of a gear 21 , This gear 21 is located in the middle of the girder bridge 6 , Each side of the gear 21 stands with a rack 6a . 6b engaged. These two racks 6a . 6b shift when turning the gear 21 the first contact surface 18 and the second contact surface 19 synchronous to each other.

8th shows a second variant of this adjustment mechanism. It is instead of the gear 21 with the racks 6a . 6b a disk 23 used. This disc 23 is in the girder bridge 6 centrally between the first contact surface 18 and the second contact surface 19 stored and has a tool intervention 22 for twisting the disc. The disc 23 is polygonal and point-symmetric and thus has different side surfaces with different distances to the center of the disc 23 on. In each case, two opposite side surfaces of the disc 23 parallel to each other and equidistant from the center of the disc 23 away. The illustrated disc 23 has eight side surfaces, creating four different variants 24a to 24d arise for the distance d. In the illustrated position of the disc 23 is the second variant 24b chosen, whereby the distance d arises. Would you like the disc 23 turn counterclockwise by one step, so ent stands the first variant 24a with the distance d '. This would increase the distance between the first contact surface 18 and the second contact surface 19 shrink, causing the door fitting 1 for a door leaf 2 could be used with lower door leaf thickness s.

In the first embodiment shown, so you choose the carrier bridge 6 in accordance with the door leaf thickness s, whereas in the second embodiment, the support bridge 6 can adapt to the corresponding door glass thickness s by an adjustment mechanism. In both embodiments, however, there is the decisive advantage that regardless of the door leaf thickness s uniform clamping plates 7 . 8th with uniformly strong intermediate layers 17 can be used. Thanks to the manufacturing method according to the invention with the injection-molded intermediate layers 17 directly on the inner surface of the clamping plates 7 . 8th no need for the complicated assembly with different distances 5 , Furthermore, there is a uniform gap between the clamping plates 7 . 8th and the door leaf 2 guaranteed whereby when placing decorative panels on the clamping plates 7 . 8th a uniform gap between decorative panels and door leaf 2 is ensured.
