Description

The invention relates to a handle assembly according to the preamble of claim 1.

Handle assemblies for windows and / or doors usually have a handle that is axially fixed rotatably mounted in a stop body and coupled via a driver with an actuator in the window or in the door. The stopper body is fastened for example by means of screws on the window frame or on the door leaf. In the stop body usually hides a locking and securing mechanism for the handle.

In window handles, the handle is usually non-rotatably connected to a bush which is supported on the inner surface of the stop body, so that applied to the handle tensile forces are transmitted to the underside of the stopper body. At the beginning of the socket locking recesses are formed, which within the stopper body with locking elements interact to mark functional positions of the window handle (see for example DE 299 22 496 U1 or DE 203 14 279 U1 ).

The arrangement of the socket and the cooperating locking elements requires a certain minimum height of the stopper body, which has an effect on the visual appearance of the handle assembly. In addition, it is often desirable or necessary for various applications of a handle assembly when the handle is provided with a rotation stop to protect the actuator formed in the door or in the window. This allows the handle to be operated only in a certain angle range.

The problem here, however, is that the overall height of the stopper body further increases, which is sometimes perceived as visually disturbing.

The object of the invention is therefore to avoid these and other disadvantages of the prior art and to provide an improved handle assembly. This should in particular have a flat as possible stop body. The handle assembly should also be inexpensive to produce by simple means.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 14.

In a handle assembly with a handle and a stop body, wherein the handle has a handle and a handle neck, and wherein the stop body has a base body with a handle facing the upper side and a handle facing away from the lower side and a locking bush, wherein the handle with the help the locking bush is axially fixed-rotatably mounted on the stop body, the invention provides that the locking bush consists of a first part and a second part, wherein the first part facing away from the handle on the side facing the handle and the second part on the handle Side of the base body is arranged, and that the handle neck is fixed in the second part of the locking bush

The particular advantage of such a handle assembly lies in the division of the locking bushing. The stopper body can be made particularly flat with his body in this way. At the same time, however, a locking device for the handle is available. The arranged on the side facing away from the handle side of the body second part of the locking bush can namely be sunk into the window frame or in the door leaf during assembly of the handle assembly to a window frame or a door leaf. The resting on the window frame or the door leaf part of the stopper body is characterized only as thick as the standing over the main body out first part of the locking bush, which is arranged on the handle side facing.

It is advantageous if the base body has a receptacle for the locking bushing. Conveniently, the first part of the locking bush can then be inserted from above into the receptacle and the second part of the locking bush can be inserted from below into the receptacle. It is altogether advantageous if the first and the second part of the locking bush each have a coupling portion, wherein the first and the second part of the locking bush are coupled to each other via the coupling portions.

The two parts of the locking bushing can then be inserted into the receptacle from the side of the abutment body facing the handle-in the following also referred to as the front side-of the abutment body and from the side facing away from the handle-also referred to below as the rear side. The two parts of the locking bush can engage with their coupling sections in each case.

It is also expedient if the locking bush receives the handle neck, especially if the handle neck is crimped with the second part of the locking bush, soldered, glued, screwed or locked. Thus, for example, both the first part of the locking bush and the second part of the locking bush each have a recess whose inner diameter corresponds to the outer diameter of the handle neck. The two recesses can in the assembled state of the handle assembly in alignment with each other, the handle neck is inserted through both. In this way, the handle neck is reliably fixed in the main body of the stopper body. At the same time holds the handle neck, the two parts of the locking bushing on the stopper body and each other firmly.

The first part of the locking bush preferably has a latching portion. In the locking portion locking devices may be formed, which cooperate with locking elements, the stopper body. For receiving the latching elements, latching recesses may be formed in the latching section.

It is also favorable if the first part of the locking bush has a neck portion. The neck section can on the one hand take the handle neck. On the other hand, it can be covered by an intermediate ring. The intermediate ring is preferably a spring element which, for example, loads a cover of the base element, so that it does not accidentally twist during use of the handle assembly.

For this purpose, the trained as a spring element intermediate ring is supported on a paragraph, which is formed at the upper end of the handle neck. The part of the handle neck lying above this shoulder is adjacent to the handle of the handle and expediently has a larger diameter than the part of the handle neck lying below this shoulder. Its outer diameter corresponds to the inner diameter of a recess which is formed in the first or second part of the locking bush and in which the handle neck is inserted in the assembled state. If the intermediate ring on the shoulder of the neck, he presses the cover against the body.

Suitably, the neck portion of the first part of the locking bush merges with a shoulder in the latching portion, wherein the latching portion has a larger outer diameter than the neck portion. The neck section, for example, extends through a cover of the base body, which is provided with a corresponding recess for this purpose.

The second part of the locking bush may have a flange portion. This can find a stop on the side of the stopper body, which faces away from the handle. In this way it can be effectively prevented that the second part of the locking bushing is pulled through the recess formed in the stopper body through, for example when the handle is actuated. On the other hand, a coupling section formed above the flange section can engage in the recess formed in the stop body and interact there with the coupling section of the first part of the locking bush.

It is also advantageous if stop elements are formed on the stop body, which form a rotational angle limit with the second part of the locking bushing. In addition, it is advantageous if locking elements are formed on the stop body, which engage in excellent rotational positions of the window or door handle in the latching portion of the first part of the locking bush. It is advantageous if the locking elements are arranged countersunk in the stop body. The stopper body can be made particularly flat in this case and just in thickness correspond to the thickness of the locking elements. At the same time then, for example, a retaining projection may be formed on the stop body, which prevents falling out of the locking elements from the stop body.

It is useful if a driver element is inserted in the handle neck and if the stopper body has a cover. The cover can be designed, for example, so that it is rotatable about the handle neck. When installed, it covers the locking mechanism and the fastening device with which the stop body is fixed to the window or to the door. For assembly or disassembly, it is rotated so that the fasteners are accessible.

In Fig. 1 can be seen a handle assembly 10, with a handle 20 which consists of a handle 21 and a handle neck 22. In the handle neck 22, a driver 80 can be used. The driver 80 has the shape of a square. The handle assembly 10 also has a stop body 30 in the form of a rosette with a base body 31 and a locking bush, which consists of a first part 40 and a second part 50. The first part 40 is arranged on the upper side of the main body 31, which faces the handle 21 of the handle 20. The second part 50 of the locking bush is arranged on the lower side of the main body 31, which faces away from the handle 21 of the handle 20.

In the main body 31, a receptacle 33 for the two parts 40, 50 of the locking bush is formed. In this receptacle 33 engage in the assembled state, both the first part 40 and the second part 50 of the locking bush.

Both parts 40, 50 of the locking bush are each equipped with a coupling portion 43, 51. The coupling portion 43 of the first part 40 and the coupling portion 51 of the second part 50 engage each other in the region of the receptacle 33. Each of the two coupling portions 43, 51 has for this purpose axial projections 431, 512, which are distributed at certain intervals over the circumference of the respective part 40, 50. Free spaces 432, 511 are formed between the axial projections 431, 512. The projections 431 of the first part 40 engage in the mounted state accurately in the free spaces 511 of the second part 50, the protrusions 512 of the second part 50 in the free spaces 432 of the first part 40th

The existing of the first part 40 and the second part 50 locking bush takes the handle neck 22, as well as in the Fig. 3 . 4 and 5 is recognizable. It can be seen that both the first part 40 and the second part 50 are each formed with a recess 44, 54 therefor. These two recesses 44, 54 go in the mounted state axially aligned with each other. Its inner diameter corresponds to the outer diameter of the handle neck 22. The handle neck 22 projects in the mounted state through the recesses 44, 54 of the two parts 40, 50 and is crimped with the second part 50, as also described in more detail below Fig. 3 recognizes. The handle neck 22 holds in this way the two parts 40, 50 fixed to the main body 31. If the two parts 40, 50 are mounted in this way on the base body 31, the coupling of the two parts produced causes the first part 40 to inevitably follow a rotational movement of the second part 50 and vice versa.

One recognizes in Fig. 1 and Fig. 2 In addition, the first part 40 of the locking bush also has a neck portion 41 through which the recess 44 extends and in which the handle neck 22 is held. The first part 40 also has a latching portion 42. In the outer periphery of this latching portion 42 locking recesses 421 are formed. These latching recesses 421 extend into the axial projections 431 of the coupling section 43. In the locking recesses 421 locking elements 38 can engage, which are arranged in the base body 31.

The second part 50 of the locking bush has, in addition to the coupling portion 51, a flange portion 53. Its outer diameter is slightly larger than the outer diameter of the coupling portion 51. At the flange portion 52 stop members 52 are formed. The stopper members 52 are formed in the form of radial projections on the flange portion 53 and have the same outer diameter as the flange portion 53. The stop elements 52 form in the mounted state of the handle assembly 10 together with a formed on the base body 31 stop ring 34 and stop members 341 formed thereon a rotation angle limit. The handle 20 can then only be rotated within an angle predetermined by the spacing of the stop elements 341 about the longitudinal axis passing through the driver 80. This limitation arises from the fact that the stop elements 52 with their side surfaces 521 on the side surfaces 342 of the stop limiters 341 find a stop, as can be seen in Fig. 4 and Fig. 5 sees.

The latching elements 38 arranged in the base body 31 are latching balls. In an alternative embodiment (not shown), latching lugs or latching projections may also be formed. The locking elements 38 are each acted upon by the force of a spring 39. It can be seen that in the main body 31 two opposing receptacles 32 are formed. These each open into the receptacle 33 for the locking bush. In the receptacles 32, a spring 39 and a latching element 38 are arranged in each case. At the edge of each receptacle 32, a retaining projection 36 is formed for the locking elements 38. This prevents the detent elements 38 designed as detent balls from falling out of the receptacles 32 during assembly of the stop body 30 or of the main body 31 on the window or on the door.

In the main body 31 also receptacles 35 are formed for (not shown) fasteners. The fasteners are used to mount the handle assembly 10 on the window or on a door.

In Fig. 1 one recognizes further that the rosette 30 has a cover 60 and an intermediate ring 70. The cover 60 is provided with a recess 61, in which the intermediate ring 70 is inserted, which in turn comprises the neck portion 41 of the first part 40 of the locking bush. The intermediate ring 70 is supported on its one side on a shoulder 221, which is formed at the upper end of the handle neck 22. With its other side it supports itself with a wave-shaped spring flange 71 axially on the top of the cover 60, so that it is pressed permanently against the main body 31. The cover 60 can be rotated about the neck portion 41, which is axially penetrated by the handle neck 22, so that the receptacles 35 are accessible to the fasteners. The width of the possible rotation of the cover 60 can be limited by a likewise formed on the base body 31 stop 37.

The intermediate ring 70 is preferably a spring element which presses the cover 60 in the resting state on the base body 31. Serves a formed on the intermediate ring 70 circumferential spring flange 71st

Also in the view of Fig. 2 it can be seen that the handle assembly 10 consists of the handle 20 and the rosette 30. The handle 20 includes the handle 21 and the handle neck 22. In the handle neck 22, a receptacle 23 for the driver 80 is formed. The stop body 30 comprises the main body 31, in which the acted upon by the force of the springs 39 locking elements 38 are arranged. Between the handle 20 and the base body 31, the cover 60 and the intermediate ring 70 are arranged. In the main body 31 engage each of the top and bottom of the first part 40 and the second part 50 of the locking bush. These are each equipped with a coupling portion 43, 51. The coupling portions 43, 51 engage each other within the base body 31 and thus cause a coupling of the rotational movement of the first and second parts 40, 50 of the locking bush, wherein a portion of this locking bush can be sunk in the window or in the door, so that the overall height of Body 31 is reduced to a minimum.

In the bottom view of Fig. 2 can be seen beyond that on the side facing away from the handle 21 of the main body 31 around the recess 33 through which the second Part 50 of the locking bush and the recorded in the second part 50 of the locking sleeve handle neck 22 are guided, a stop ring 34 is formed. At this stop ring 34 stop elements 341 are formed. These are radial projections which interact with the abutment elements 52 of the second part 50 of the locking bushing as described above.

One recognizes in Fig. 2 Furthermore, the formed in the second part 50 of the locking sleeve edge 55, with which the handle neck 22 is verschördelbar.

One recognizes in Fig. 3 in addition, one of the two securing cams 351, in which the recesses 35 are formed for the fastening means (not shown). The illustrated safety cam 351 is in perspective behind the cross-sectional plane of the Fig. 3 , the second securing cam 351, not shown, is located in front of the cross-sectional plane of the Fig. 3 and is therefore not recognizable. It is also conceivable, however, that the handle assembly 10 in an alternative embodiment has only one securing cam 351 and correspondingly only one receptacle for a fastening means.

Furthermore, one recognizes the formed on the second part 50 of the locking sleeve flange edge 53 with the - also in perspective behind the cross-sectional plane of the Fig. 3 lying - stop element 52. In Fig. 4 it can be seen how this stop element 52 bears against one of the stop elements 341 formed on the stop ring 34. The stop ring 34 in this case has two of the stop elements 341 in the present embodiment. Between the side surfaces 342 of these stop elements 341, the stop element 52 formed on the flange ring 53 can be moved back and forth. In this case, the side surfaces 521 of the stop element 52 come to lie on the side surfaces 342 of the stop element 341. Ideally, the outer stop positions coincide with the latching positions which are predetermined by the latching depressions 421 of the latching section 42 of the first part 40 of the latching bushing.

In Fig. 5 it can be seen that two stop elements 341, 52 are formed in the handle assembly 10 shown both on the stop ring 34 and on the second part 50 of the locking bush. The handle 20 is thus swingable back and forth between two excellent end positions. If the handle 20 is in one of these two end positions, then the side surfaces 521, 342 of the stop elements 52, 341 abut one another. It can also be seen here that the driver 80 is arranged in a recess 23 of the handle neck 22. The handle neck 22 is in the recess 54 of the second part 50 of the locking bush and the second part 50 of the locking bush is arranged in the recess 33 which is formed in the base body 31 of the rosette or the stopper body 30.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways.

It is expedient if the base body 31 has a receptacle 33 for the locking bush, wherein the first part 40 of the locking bush inserted from above into the receptacle 33 and the second part 50 of the locking bush is inserted from below into the receptacle 33, and if first and the second part 40, 50 of the locking bushing each having a coupling portion 43, 51, wherein the first and the second part 40, 50 of the locking bush via the coupling portions 43, 51 are coupled together.

It is also advantageous if the locking bushing receives the handle neck 22, wherein the handle neck 22 is crimped with the second part 50 of the locking bush, soldered, glued, screwed or locked.

It can also be seen that it is advantageous if the first part 40 of the locking bushing has a latching section 42 when the first part 40 of the latching bush has a neck section 41 and when the second part 50 of the locking bush has a flange portion 53. It is expedient if 31 stop members 34 are formed on the base body, which form a rotational angle limiting with the second part 50 of the locking bushing and when on or in the base body 31 locking elements 38 are formed in excellent rotational positions of the window or door handle 20 in engage the locking portion 42 of the first part 40 of the locking bush.
