Definitions

  • the invention relates to a door fitting a door handle mounting according to the preamble of claim 1.
  • Door fittings for the installation of door handles are well known, wherein the door handles are secured by means of retaining rings against pulling out of the lock when mounting door handles on a door or a lock. From this, during installation, a special tool is used to be able to arrange the retaining rings.
  • a door fitting which comprises a base fitting, which in particular comprises a base rosette and is suitable for mounting on a door leaf. Further, the door fitting comprises a Unterrosette for supporting a door handle, which is engageable with the base fitting in rotationally fixed engagement. For axial fixation of the lower rosette with respect to the base rosette, a fixing spring is used.
  • the structure of this fitting is complex with relatively many items that require a high assembly cost.
  • the known door fittings have metallic guide bushes, which are lubricated for a guaranteed sliding property, which is to be regarded as disadvantageous.
  • Another disadvantage is the installation of door handle and door fitting the use of spring washers and washers, which ensure a low clearance between the door handle and fitting base.
  • the invention includes the technical teaching that the lower part and the guide bushing are positively connected with each other in a form-locking manner and the guide bushing has at least one portion which engages in a recess of the Matdrückerlochteils latching when receiving the pusher hole in the guide bushing.
  • the embodiment according to the invention has the advantage that a fast tool-free assembly of the lower part with the guide bush takes place by the latching connection, wherein the assembly of the door handle with the guide sleeve can also be performed quickly and without tools by the latching connection.
  • the lower part has a shape contour which rests positively on a arranged on the guide bush survey. As a result, a locking connection of the two parts to be joined is made possible by simple shapes.
  • the guide bush has a circumferential preferably cylindrical outer surface on which the survey is arranged. Since the Schod Wegerlochteil the door handle is formed in a round shape, it makes sense to form the guide bush in a cylindrical shape, wherein when mounted with the lower part of the guide bush can be inserted into the opening of the lower part and locked without orientation.
  • the survey is arranged circumferentially on the outer surface.
  • the circumferential elevation on the guide bushing provides a larger area, which rests against the shape contour of the lower part, in order to absorb forces arising.
  • the guide bushing has a collar which rests with its surface on a surface arranged on the lower part.
  • the support of the surface of the collar on the surface of the lower part is used in the assembly process of the locking connection between the lower part and guide bushing as a latching stop, wherein in the manufacture of the guide bush a dimensional adjustment can be made to ensure the locking connection almost without play.
  • the portion of the guide bush is formed as a lip, which is arranged on a preferably cylindrical inner surface of the guide bush. Since the door handle hole part of the door handle is formed in a round shape and is to be guided in the guide bush, offers a cylindrical configuration of the inner surface of the guide bush, wherein in the manufacture of the guide bush, the lip can be arranged in a simple manner.
  • the lip is arranged circumferentially on the inner surface of the guide bush. As a result, the lip offers a large contact surface, in the locked state with the door handle hole part provides a high holding force that holds the door handle in this connection.
  • the advantage is that the guide bush with the lower part in the mounting direction on the axis of pressure-resistant and tensile strength in the opposite direction of the mounting direction is connected via the axis. This ensures that the connection between the lower part and the guide bush remains permanently fixed, although tensile forces and compressive forces act on the door fitting over the door handle during operation.
  • the pressure-resistant connection between the guide bush and the lower part is effected by the surface of the collar of the guide bush and the surface of the lower part.
  • the tensile connection between the guide bush and the lower part is carried out by the collection of the guide bush and the shape contour of the lower part.
  • the material of the guide bushing is a plastic.
  • the plastic material By using the plastic material, a cost-effective production of the guide bush is possible, with a simple dimensional adjustment can take place.
  • the guide bush is self-lubricating.
  • a maintenance-free guide bushing is used, which supplies the operating door handle with lubricant, whereby the contact surfaces low friction is ensured.
  • the guide bushing has locking elements on their surfaces. Locking elements on the outside and the inside of the guide bushing serve a two-sided locking connection, the guide bushing itself latching in a counterpart - here the lower part - can be attached and they themselves another object - here the door handle hole part - can record detent.
  • the locking elements are formed as at least one elevation and at least one lip. Since the guide bush is made of plastic, a simple and inexpensive shaping of the survey and the lip is ensured.
  • a cover protects the lower part and the guide bush from contamination.
  • the cover is clip-connected in a conventional manner to the base, whereby the base and the guide bush covered by the cover and thus keeps impurities away, to ensure the function between the guide bush and the pusher hole part.
  • Fig. 1 shows the assembled door fitting 13 with the mounted door handle 4 in a perspective view, wherein the cover 3, the lower part 1 and the guide bushing 2 covers.
  • the door handle 4 is inserted through an opening of the cover 3 in the guide bushing 2 latching, wherein the guide bushing 2 is also latchably connected to the lower part 1.
  • Fig. 2 shows an exploded view of the door fitting 13 and the door handle 4 in a perspective view, wherein an axis 14 represents the axis over which the guide bush 2 is to be mounted in the opening 6 of the lower part 1 and then the cover 3 by clip connection to the lower part 1 assemble is.
  • the door handle 4 is through the opening of the cover 3 in the designated opening guided guide bush 2 and mounted in the guide bushing 2 detent.
  • the guide bush 2 is annularly formed with a shaft having a cylindrical shape, wherein the guide bush 2 has a corresponding outer surface 2a and an inner surface 2b.
  • the mounting direction 15 illustrates the assembly of the items.
  • Fig. 3 shows the lower part 1 and the guide bush 2 in full section and the door handle 4 in a position before mounting in a side view, for reasons of clarity, the cover 3 in the Fig. 3 is removed.
  • the lower part 1, the guide bush 2 and the door handle 4 are arranged one above the other on the axis 14.
  • the door handle 4 has a door handle hole portion 4a, on which a guide 8 and a slope 8a, which is provided for insertion into the guide bush 2, are arranged, wherein preferably in the region of the guide 8 a recess 9 is arranged.
  • the slope 8a serves to facilitate insertion of the door lever hole part 4a in the guide bushing second
  • the guide bush 2 is constructed like a ring with a shaft, wherein on the preferably cylindrical outer surface 2a, a survey 5 is arranged.
  • the inner surface 2b of the guide bush 2 is dimensionally designed such that the door handle hole part 4a and thus the guide 8 is to be inserted with a very small gap in the opening provided in the guide bushing 2.
  • a collar 12 is arranged, which is made dimensionally larger than the cylindrical outer surface 2a of the guide bushing 2. This results in a shaft of the guide bush 2 towards the surface 12a, the with a surface 11 located on the base corresponds, wherein the shaft of the guide bush 2 is formed by the outer surface 2a.
  • the lower part 1 is also of annular construction, wherein a passage is arranged on the lower part 1 in its central region.
  • This passage is annular and has an opening 6, wherein at one end of the passage, which is aligned in the direction of the door handle 4, a surface 11 is arranged, which corresponds to the surface 12 a of the guide bush 2.
  • the second end, which is arranged on the opposite side of the surface 11 of the lower part 1, has a shape contour 7, which is formed in this embodiment as a radius. Other shape contours are conceivable, however.
  • Fig. 4 shows the lower part 1 with the assembled guide bushing 2 in full section and the door handle 4 with its door handle part 4a before mounting in the guide bush 2 in a side view, for reasons of clarity, the cover 3 in the Fig. 4 is removed.
  • Fig. 4 further shows a detail Y of the assembly of the base 1 with the guide bushing 2.
  • the detail Y illustrates the assembly of lower part 1 and the guide bush 2, wherein the surface 12a of the guide bush 2 rests on the surface 11 of the lower part 1.
  • the elevation 5, which is arranged on the outer surface 2a of the guide bush 2 abuts against the contour of the mold part 7 of the lower part 1, wherein a latching connection between the lower part 1 and the guide bush 2 is produced by this form-fit.
  • the inner surface 2b of the guide bush 2 is indicated on which a lip 10 is arranged.
  • Fig. 5 shows an assembly of the door fitting 13 with the door handle 4, wherein the guide 8 of the door handle part 4a is engaged in the intended opening of the guide bush 2, in a side view, wherein the lower part 1, the guide bush 2 and the cover 3 are shown in full section and a Detail X of the assembly of the lower part 1 with the guide bushing 2 and the door handle 4.
  • the detail X illustrates the locking of the lower part 1 with the guide bush 2 due to the mold contour 7 and the survey 5.
  • the locking between the guide bush 2 and the door handle part 4a and thus the door handle 4 can be seen, which due to the recess 9 and the lip 10, which is engaged in the recess 9, is made possible.
  • a guide bush 2 is used, which consists of plastic and ensures a self-lubricating effect between the guide bushing 2 and the lower part 1 and between the guide bushing 2 and the door handle hole part 4a.
  • This guide bushing 2 can be connected to the lower part 1 in a latching manner without a tool, wherein it is inserted into the opening 6 of the lower part until the guide bush 2 engages in the lower part 1.
  • the elevation 5 protrudes from the outer surface 2a of the guide bush 2, which simultaneously leads to the dimensional configuration of the elevation 5 being greater than the dimensional configuration of the outer surface 2a of the guide bush 2. If one then sets the outer surface 2a is based on a diameter value, for example X, the outer surface 2a has a diameter X. Accordingly, the elevation 5 has a dimensional configuration which is greater than X. Preferably, the dimensional configuration of the survey 5 is formed substantially larger than X.
  • the detail Y further clarifies that the outer surface 2a of the guide bush 2 is based on the wall of the opening 6 of the lower part 1, wherein joining tolerances are to be considered in order to introduce the guide bush 2 in the opening 6 of the lower part 1, whereby a very small Gap between lower part 1 and guide bush 2 is present.
  • the dimensional configuration of the survey 5 is greater than the dimensional configuration of the opening 6, which also has the consequence that the survey 5 receives a locking connection with the mold contour 7 of the lower part 1.
  • the cover 3 is then attached to the lower part 1, with clip hooks prevent the cover 3 unintentionally detached from the lower part 1. Subsequently, the door handle 4 is inserted with its door handle hole part 4a in the intended opening of the guide bush 2 until the lip 10 of the guide bush 2 engages in the recess 9 of the door handle part 4a.
  • the inner surface 2b of the guide bush 2 is designed such that, with consideration of joining tolerances, it rests against the guide 8 of the door presser hole part 4a of the door handle 4 with a very small clearance. This ensures that the elevation 5 remains on the mold contour 7 and is not transported by external influences acting through the door handle 4 on the door fitting 13, from this position.
  • the complementary contours between the guide 8 of the door lever part 4a and the inner surface 2b of the guide bush 2 and the complementary contours between the lower part 1 and the guide bush 2 form an axial securing in the assembled state ensure that accidental removal of the door handle from the door fitting 13 is avoided.
