Description

The invention relates to a pusher arrangement for a particular lockable and / or unlockable lock a door, a window or the like, with a handle preferably in the form of a knob, a latch or the like, which is rotationally connected to a shaft operatively connected to the lock , Wherein the handle is attached tap-proof on the shaft.

Handle arrangements of the generic type have a shaft operatively connected to a lock. For the purpose of rotational movement of the shaft this is rotationally connected to a handle, which can be taken if necessary by a user and operated.

The handle is typically mounted on the lock-removed end of the shaft in the case of installation and secured against axial displacement in the longitudinal direction of the shaft by means of a grub screw. In the case of dismantling a removal of the handle is readily possible after loosening the grub screw.

Although the above construction has been proven in everyday practice, it is not free from disadvantages. Thus, the possibility of being able to pull off the handle in a simple manner from the shaft is a safety-related problem, in particular in the case of electronically lockable and / or unlockable locks, the electronics of which are arranged partly within a volume space provided by the shaft. After a removal of the handle namely a comparatively easy access to the lock and / or the electronics in the case of an electronically lockable and / or unlockable lock possible. To address this problem, known from the prior art constructions have additional safety devices in the form of, for example, additional sleeves, discs and / or the like components, making the construction more complex and thus more expensive both in the production and in the assembly and / or Disassembly makes.

A generic pusher arrangement is from the DE 20 2005 017 497 U1 known. This pusher arrangement is provided for components such as windows, doors and the like and has a handle and a driver element, which is rotatably engageable with the handle engaged. It is provided that between the handle and the driver element, a device is provided which is designed such that the leadership of the driver element in the handle in a first direction effected and locked in the opposite direction.

From the GB 2 335 478 A An arrangement for securing handles on different sides of a movable sash is known. This arrangement has, at opposite ends of a shaft which is rectangular in cross-section, two handles which can be fixed to the shaft via set screws. These grub screws are aligned with their longitudinal axis direction at right angles to the longitudinal axis direction of the shaft, wherein the shaft in the region of the engaging grub screws each having a strip of material into which the grub screws can penetrate, so that the two handles depending on the thickness of the sash at the intended location can be fixed.

Finally, the reveals US 1,405,695 a two-part shaft with a rectangular cross-section, wherein the two parts of the shaft are bolted together. For this purpose, a part of the shaft has a threaded portion and the second part of the shaft has a thread corresponding thereto.

Handles are placed on the ends of the shaft sections, wherein a handle is designed such that it can be fixed in different positions relative to the shaft section. For this purpose, the shaft portion has a plurality of holes into which a grub screw screwed into the handle and extending at right angles to the longitudinal axis of the shaft portion can be screwed.

It is therefore an object of the invention to improve a handle assembly of the generic type to the extent that at the same time a simple construction safety-relevant aspects is taken into account.

To solve this problem, the invention proposes a guide element (12), via which the handle (2) is displaceably arranged on the shaft (3) so that the guide element (12) is not nondestructively accessible and a position element is provided , which fixes the handle (2) in the final assembled state.

The above object is achieved with the invention in a very simple way. The handle is plugged in a conventional manner to the castle remote end of the shaft, in contrast to the prior art, however, abziehsicher. The handle for the handle assembly according to the invention can therefore not be deducted from the shaft after a previous release, for example, an externally accessible grub screw in a simple manner. The handle according to the invention is insofar a security against manipulation of the thus operable lock increasing function, because a direct access to the lock and / or the electronics in the case of an electronically lockable and / or unlockable lock as a result of peel-proof arrangement of the handle on the shaft is prevented. This tamper protection is provided with a simple design at the same time.

The peel-proof arrangement of the handle on the shaft is achieved according to the invention in that the handle has a guide element that engages in the final assembled state in a recess of the shaft, which extends in the longitudinal direction of the shaft and is preferably formed like a groove.

Both the groove-like depression in the shaft and the guide element provided by the handle are not easily accessible from the outside in the case of a final-mounted handle, that is to say preferably not non-destructively accessible. The handle itself covers in the final assembled state, the groove-like depression in the shaft, so that access from outside the bottom is not possible.

The guide element may be formed integrally with the handle. Such a configuration is particularly useful when the handle, for example, off Plastic is formed.

According to an alternative embodiment of the invention comes as a guide element but also a separate component into consideration, which is screwed to the handle, glued, riveted, welded or otherwise connected.

The guide element may be formed, for example, pin-shaped. It comes, for example, a screw, preferably a grub screw into consideration. This can be used, for example, in an initial installation via an externally accessible hole in the handle, in such a way that it engages with its end portion in the recess provided by the shaft, whereby the Abziehsicherung is formed. After completion of this initial assembly then the externally accessible bore can be closed, so that a subsequent access to the serving as a guide element grub screw is not possible. Instead of a grub screw and a simple pen body can be used, for example, a bolt or the like, which is glued in the context of an initial assembly in a designated hole of the handle.

According to an alternative embodiment of the invention it is provided that the guide element is resilient. This embodiment has the advantage that following a first installation, a hole provided for this purpose and accessible from the outside does not have to be closed again in the handle, as is the case with the embodiment described above. A spring-elastic trained guide element is biased resiliently for assembly purposes. After attaching the handle to the shaft, the guide element snaps resiliently into the recess provided by the shaft, as soon as the guide element reaches the recess in the course of an attachment of the handle and the shaft. After snapping the guide element into the recess of the shaft a peel-off connection between the shaft on the one hand and handle on the other hand is reached, which can not be easily solved.

According to a further feature of the invention, the guide element on the well side has an extension which is designed in the manner of a carriage and preferably engages exactly contoured in the groove-like depression of the shaft. This embodiment has the advantage that the handle due to the interaction between Guide element on the one hand and recess on the other hand axially in the longitudinal direction of the shaft is guided in a special way. Of course, such a guide is also given without a slide-shaped extension, namely the fact that, for example, the pin-shaped guide element engages in the recess provided by the shaft for the purposes of pull-off protection.

The above-described construction provides essentially two advantages. The handle is on the one hand in the longitudinal direction of the shaft slidably disposed on this, but at the same time not easily deducted from this, so that on the one hand the vorerläuterten safety aspect is taken into account, on the other hand, but also the possibility of the handle in their relative longitudinal alignment to the shaft to be able to adapt to different thickness door leaves, windows or the like. Thus, the trigger assembly according to the invention with simultaneous pull-off security with respect to the handle for thick thickness in the direction of trained doors, windows or the like can be used. Previously known presser arrangements are unable to perform this dual function.

To fix the handle relative to the shaft in the longitudinal direction of the shaft, the handle has a position element which engages in the final assembled state in a provided by the shaft blind hole. Such a position element may be, for example, a grub screw, which is easily accessible from outside to fix the handle relative to the shaft.

Preferably, the shaft has a plurality of blind holes, which are arranged one behind the other in the longitudinal direction of the shaft. This allows an axial fixation of the handle relative to the shaft in one of the plurality of blind holes corresponding number of positions. In the thickness direction differently thick trained door leaves, windows or the like can be taken into account.

With the handle design according to the invention, a construction is proposed as a whole which makes it possible, on the one hand, to satisfy special safety-relevant aspects, since the handle, due to its non-peelable arrangement on the Shaft can not be easily removed from the shaft, but on the other hand it also allows to be adapted to differently thick door leaves, windows or the like can be, regardless of the door leaf thickness, window frame thickness or the like fixing the handle against the Shaft in the axial direction is possible.

in a schematic view from above the shaft of the handle assembly according to the invention Fig. 1 in a second embodiment.

Fig. 1 shows the trigger assembly according to the invention in a first embodiment according to a first installation situation.

The pusher assembly 1 has a handle 2, which is formed in the embodiment shown as a rotary knob. The handle is rotationally connected to a shaft 3. This protrudes through a formed in a door leaf 6 through hole 7 and is operatively connected to a in Figs. not shown lock. For handling side cover of the through hole 7 is used in a conventional manner an intermediate disc 8, which is arranged between the door leaf 6 and handle 2.

As in particular the representation after Fig. 4 can be seen, the shaft 3 consists of a first shaft section 4 and a second shaft section 5. The first Shaft section 4 is circular in cross-section, whereas the second shaft section 5 is formed in cross-section deviating from the circular shape. The deviating from the circular cross-sectional education of the second shaft portion 5 ensures the rotationally fixed arrangement between the handle 2 on the one hand and shaft 3 on the other.

The handle 2 is according to the invention abziehsicher placed on the shaft 3. This is achieved in that the handle 2 has a guide member 12 which engages in the final assembled state einendseitig in a provided by the shaft 3 recess 11, which, in particular a synopsis of FIGS. 1 and 4 shows, extending in the longitudinal direction 10 of the shaft 3 and is formed in the manner of a groove. The recess 11 has the shape of a bag long hole bore, which may be formed for example by means of milling. The recess thus created has with respect to the plane of the drawing Fig. 1 Left and right side over a boundary in the form of a wall, so that the handle 2 due to the engaging in the recess 11 guide member 12 is not deducted from the shaft 3, that is, with respect to the plane of the drawing Fig. 1 stripped to the right of the shaft 3 is still pushed beyond the second shaft portion 5, that is, with respect to the drawing plane to Fig. 1 can be moved to the left over the axial extent of the recess 11 in the longitudinal direction 10 addition. The handle 2 is consequently connected to the shaft 3 so that it can not be pulled away, wherein an axial adjustment possibility, that is to say a setting possibility in the longitudinal direction 10 of the shaft 3, is advantageously given at the same time.

According to the in the FIGS. 1 and 2 In the embodiment shown, the handle 2 has a volume space 17. The guide element 12 consists of a spring-elastic pin 13 on the one hand and an extension 14 arranged thereon, which is formed corresponding to the width contour of the recess 11. For the purpose of initial assembly of the pin 13 can be pivoted together with the extension 14 arranged thereon resiliently in the space provided by the handle 2 volume space and / or moved. After insertion of the second shaft portion 5 of the shaft 3 in the cavity 9 of the handle 2, that is, after plugging the handle 2 on the second shaft portion 5 of the shaft 3, the resilient pin 13 of the guide member 12 pivoted back into his in the FIGS. 1 and 2 shown normal position in which the shaft-side end portion of the pin 13 and carried by the pin 13 extension 14 engage in the recess 11 of the shaft 3, whereby the previously described peel-off connection between the handle 2 and the shaft 3 with simultaneous displacement possibility of the handle 2 relative to the shaft 3 in the longitudinal direction 10 is reached.

For fixing the handle 2 relative to the shaft 3 in the longitudinal direction 10 is a in FIGS. Not shown in detail position element, which may be formed for example in the form of a grub screw and is inserted into a bore 16 of the handle 2. About the bore 16 of this position element is readily accessible from the outside, which allows it to screw in the case of a grub screw in an associated blind hole 15 of the shaft 3, for example. When engaging in a blind hole 15 position element, the handle 2 is axially secured relative to the shaft 3, that is, a displacement of the handle 2 relative to the shaft 3 in the longitudinal direction 10 is not possible.

As the FIGS. 1, 2 and 4 can be clearly seen, the shaft 3 has a plurality of blind holes 15 which are arranged one behind the other in the longitudinal direction 10. This allows an axial securing of the handle 2 with respect to the shaft 3 in different axial positions. Differently thick door leaves 6 can thus be taken into account, such as a comparison of FIGS. 1 and 2 shows, where Fig. 1 in contrast to Fig. 2 a comparatively thin door leaf 6 shows.

The blind holes 15 can - as in a first embodiment in Fig. 1 is shown - the groove-like recess 11 may be formed opposite. An alternative embodiment is in Fig. 4 shown, accordingly, the groove-like recess 11 and the blind holes 15 with respect to the plane of the drawing Fig. 4 are formed on the same shaft surface side.
