Description

The invention relates to a pair of door handle with Türdrückerklemmbefestigung with a releasably inserted in an insertion of a door handle neck and fixable by means of the lever handle a retaining screw in the insertion festlegbaren, provided with a through hole for receiving a pusher mandrel, square in cross-section insert part, which is at least a part of the insert has forming, resiliently against a latching teeth of the insertable into the insert part pusher mandrel engageable locking spring.

Türdrückerklemmbefestigungen are generally designed such that a door handle of a door fitting is firmly connected to the door handle mandrel, while the second door handle is releasably attached by means of a cooperating with a locking spring locking teeth on the pusher mandrel. The attachments of the two door handle of a door fitting are thus usually designed differently.

A generic door handle pair with clamp attachment with the features described above discloses the DE-OS 19 30 679 wherein the locking teeth of the pusher mandrel has a concave longitudinal groove, in which engages a locking spring, which is supported with a hump-like curvature on a wall of the insertion opening. The insertion opening is cylindrical and takes over part of its length in one of the two door handle, the cylindrical male part.

A door lever connection with an inserted into a stepped insertion of the two opposite door handle insertion sleeve with a stepped through hole describes the DE 74 25 072 U1 , wherein the insert bushings are firmly glued to the handle neck and only one of the two door handle with its insert sleeve with interposition a spring clip the locking teeth of a pusher mandrel covered.

A firmly connected with one of the two door handle pusher mandrel, which is clamped in the insertion of the other door handle by means of a located at a fixed insertion opening in the insert part locking spring is through the DE-AS 12 58 758 known. The insert consists of two opposing locking springs, which engage with correspondingly shaped indentations in a circular cross-sectional detent toothing of the pusher mandrel.

An exclusively consisting of a locking spring, arranged in two opposite door handles insert is the subject of DE 42 34 870 C1 , The Lever handle necks have a stepped insertion opening, wherein the latching in the axial direction of the pusher mandrel causing a loose part forming locking spring is arranged in the larger diameter step the gradation of the insertion and the rotation of the pusher mandrel by engaging the free end of the pusher mandrel in the smaller diameter stage is effected.

The object of the invention is to provide a door handle pair with Türdrückerklemmbefestigung, in which both the insert and the pusher mandrel are positively and rotationally mounted in the pusher neck. In this case, manufacturing tolerances in the region of the insertion of the pusher neck should be compensated by means of the insert. An essential part of the task is the Türdrückerklemmbefestigung with respect to both opposite door handle of a door fitting in such a way that by replacing the insert parts of a door fitting with a smaller diameter or larger passage opening with simple means an adaptation to pusher mandrels different Diameter is possible. The same applies to the adaptability to the diameter of different insertion in the pusher neck.

The invention solves the problem set with the features of claim 1.

Further advantageous embodiments of the invention are the subject of the dependent claims.

With the doctrine according to claim 1 takes place in the region of the grooves having longitudinal portion of the insertion the tensile and pressure resistant and torsion-resistant mounting of the insert in the insertion of the door handle neck, wherein the rotation ensured by the integrally formed on the insert, enclosing the longitudinal groove of the pusher neck chamber guide is, at the same time in this area, the locking spring is arranged. The insertion opening has a larger diameter between the grooves, so that the arrangement of an integrally formed with the insert part, sufficiently strong locking spring is made possible due to this free space. The engaging in the groove-free longitudinal portion of the insertion and directed against the bottom of the bag-like insertion opening portion of the insertion part enclosing the free end of the pusher mandrel; can compensate for manufacturing tolerances between the insertion opening and the pusher mandrel in this area and forms an additional anti-rotation device for the pusher mandrel. The arrangement of the invention Türdrückerklemmbefestigung at each two opposite door handles of a door fitting made possible by changing the insert with modified passage opening to the adjustment mandrels with different diameters or with different insertion, so that the need to adapt the insertion of a door handle to a pusher mandrel predetermined diameter deleted. This leads to a Unification in the production of door handles. For example, door handles can be fitted with a designated for a pusher mandrel with an outer diameter of 9 mm insertion on a pusher mandrel with an outer diameter of 8 mm.

In an embodiment of the invention, the insertable into the longitudinal groove of the insertion chamber guide is designed such that it projects beyond an outer wall of the insert part, d. H. forms one or more over the outer wall of the insert projecting ribs which form-fit the aforementioned longitudinal groove, wherein in a preferred embodiment, two such chamber guides are provided, which are each arranged on opposite outer walls of the insert part. In this case, one of the two chamber guides can be made longer, while the second chamber guide is designed to be shorter and merges into the one-piece component of the outer wall forming locking spring.

According to a further feature of the invention, arranged on an outer wall of the insert part on the outer wall projecting centering lug for the retaining screw; the centering approach fixed in cooperation with the retaining screw insert in the insertion of the door handle neck and can simultaneously with appropriate action - in addition to the function of the locking spring - to lock the Drükkerdorn in the pusher neck.

The individual components of the Türdrückerklemmbefestigung including the door handle, the pusher mandrel and the Türdrückerklemmbefestigung can basically consist of any suitable material; However, it has proven to be advantageous in terms of manufacturing technology and cost, if the insert is made of a suitable plastic.

The invention will be explained in more detail with reference to an embodiment.

A door handle 1 according to FIG. 1 has in the region of a door handle neck 2 an insertion opening 3, in which a pusher mandrel 4 is inserted. The insertion opening 3 has the same inner diameter over its entire length, wherein two opposite longitudinal grooves 12 are provided in the region of the inner wall of the insertion opening 3 in a section a adjacent the door leaf. A generally designated 7 insert (see in particular FIGS. 4 to 7 ) has on two opposite outer walls 16 and 17 referred to as chamber guides 13 and 14, respectively raised reinforcements which engage in the longitudinal grooves 12. It can be seen that the arranged on the outer wall 16 the chamber guide 13 is formed longer than the arranged on the outer wall 17 chamber guide 14. The chamber guide 13 terminates leaving a gap 19 in a centering approach 18, in which a the Türdrückerhals 2 durchfassende retaining screw 5 can be screwed is, so that the retaining screw 5, the insert part 7 is locked in the door handle neck 2 and can additionally lock the passage opening 6 of the insert part 7 through the pusher mandrel 4 with appropriate loading. An essential part of a generally designated 8 Türdrückerklemmbefestigung is formed after the chamber guide 4 and part of the insert part 7 forming locking spring 10 which engages with a formed at its free end latch hook 11 in an associated locking teeth 9 of the pusher mandrel 4.

How the particular Figures 1 and 2 identify, the longitudinal grooves 12 in the insertion opening 3 of the door handle neck 2 are executed only over the length section a, while the insert part 7 beyond in the region of the longitudinal section b - that is directed against a bottom 15 of the insertion 3 - extended. As a result, manufacturing tolerances with respect to the pusher mandrel 4 or the insertion opening 3 over the entire length of the insertion opening 3 can be compensated by appropriate adaptation of the insert part 7. The through-opening 6 of the insert part 3 can be adapted to the diameter of the pusher mandrel 4 used, as required.
