Definitions

  • the invention relates to a window handle fitting with a window gear installed in a window sash, which comprises a gear element rotatable about an axial direction, in particular a gear nut, for opening and closing a window, with a pusher element, and with a torque transmission element, in particular a square element, which is in a Mounted state of the window handle fitting is releasably connected to the gear element in order to transfer a pivoting movement of the pusher element into a rotation of the gear element about the axial direction, and in the assembled state the pusher element is attached to the torque transmission element and releasably connected to it in a captive manner.
  • a window handle fitting in the context of the present application means that part of the window fitting that is arranged in the area of the window handle.
  • a window fitting is to be understood as the mechanism for opening and closing the window or for locking and unlocking it.
  • a window handle according to DIN 18267: 2015-02 is attached to the window handle fitting.
  • a window handle fitting is to be distinguished from a door fitting or door lock or a door lock mechanism, which is to be connected to an associated door handle in accordance with DIN 18255 for actuation.
  • Door locks are usually equipped with a spring mechanism that biases the door handle into a certain position.
  • Door fittings are usually equipped with a door handle from two sides, while window handle fittings are only equipped with a corresponding window handle on one side.
  • window handle fittings with the features just mentioned, in which the pusher element and the torque transmission element are connected to one another.
  • the connection of the pusher element and the torque transmission element can either be detachable or non-detachable.
  • the pusher element and torque transmission element are often pressed together so that they are permanently connected to one another.
  • the AT 377 312 shows a trigger pin which can be expanded by means of a clampable sleeve.
  • the DE 1 257 035 an expandable interchangeable pin which can be expanded by means of a pressure screw arranged in the interchangeable pin.
  • the EP 1 114 905 A1 shows a mounting sleeve for the fixed attachment of a door handle.
  • the DE 1 117 442 and DE 42 34 870 each show latching connections for attaching a pusher element to a square.
  • a substructure is arranged in conventional window handle fittings.
  • the substructure is rotatably connected to the pusher element.
  • the substructure is fastened to the window sash by means of screws which are passed through the receptacles, and thus indirectly also the pusher element or the torque transmission element connected to it is connected to the window sash.
  • a cover rosette is provided to cover the substructure, which is clipped onto the substructure and is also arranged on the neck section of the pusher element. If the cover rosette is removed, the screws on the substructure are accessible and can be removed. By removing the screws, the pusher element, the substructure and the torque transmission element can be removed from the window sash.
  • window handle fittings A problem with such window handle fittings is that the fastening by means of the substructure requires installation space that extends beyond the outline of the neck section of the pusher element. With conventional window handle fittings, care must also be taken to ensure that the screws are attached to the substructure without damaging the window sash. For example, the screws of the substructure can be inserted in the wrong places in the window sash, which means that the window sash has to be replaced.
  • the object of the present invention is to provide a window handle fitting which is space-saving and can be securely attached to the window sash in a simple manner.
  • This object is achieved by a window fitting with the features of claim 1.
  • the window handle fitting according to the invention is characterized in that, in the assembled state, the torque transmission element is fastened in a form-fitting manner, engaging behind the gear element in the axial direction, in such a way that the pusher element can be detached from the torque transmission element without the need to release the fastening of the torque transmission element with the transmission element, which engages behind in an axial direction, in a form-fitting manner , wherein the fastening of the torque transmission element, which engages behind in a form-fitting manner in the axial direction, comprises a screw which, in the assembled state, extends in the axial direction through the torque transmission element and is screwed to a counterpart on the window gearbox side.
  • the torque transmission element is fastened more or less independently with respect to the transmission element.
  • the pusher element can be added or removed independently of the torque transmission element.
  • the pusher element is therefore fastened independently of the torque transmission element.
  • the pusher element can be attached to the torque transmission element. This eliminates the need to attach the pusher element to the substructure.
  • a substructure is either not necessary or can be designed in such a way that it is not used for fastening. As a result, any substructure can be made much more space-saving and smaller.
  • the neck section of the pusher element which extends in the axial direction, extends in the radial direction at least as far as a substructure of the window handle fitting.
  • the substructure when looking along the axial direction, the substructure is virtually covered by the neck section of the pusher element.
  • the entire construction is designed to be particularly space-saving and visually appealing.
  • the cleaning of the window sash of this type is particularly simple, since cleaning only has to be carried out around the outlines of the neck section.
  • the formation of the torque transmission element with a screw represents a structurally uncomplicated, efficient and safe way of fastening the torque transmission element with respect to the transmission element.
  • the counterpart is non-rotatably connected to the gear element.
  • the torque transmission element can be braced against the gear element via the screw.
  • the pusher element, torque transmission element, gear element and counterpart then pivot together.
  • the counterpart can advantageously be designed as part of the gear element or integrated into it, which makes the assembly of the individual components of the window handle fitting simple.
  • the counterpart can be designed as a nut which is fastened to the gear element via an injection-molded part.
  • the counterpart can then almost in one work step together with the transmission element are inserted into the window sash, the entire window construction is closed and then the torque transmission element can be screwed to the counterpart on the window transmission side by means of the screw, whereby the torque transmission element is attached to the transmission element.
  • the counterpart is connected to the window gear or the window sash in a rotationally fixed manner.
  • the counterpart is arranged to be rotatable with respect to the gear element, but non-rotatably with respect to the other components of the window gear and the window sash.
  • the screw for fastening the torque transmission element is in turn screwed into the counterpart and extends through the torque transmission element.
  • the torque transmission element is rotated relative to the screw and the counterpart and rotates the gear element.
  • the counterpart can be designed as a nut which has an extrusion coating that engages in corresponding recesses on the window profile or in components of the window gear.
  • an anti-rotation lock with respect to the window profile can be implemented in a simple manner.
  • the counterpart can also be designed as a plate with blades with a thread, the blades of the plate being able to engage, for example, in screw receptacles of a conventional window gear. This will result in A rotation lock with respect to the window profile is implemented in a similarly simple manner.
  • Such conventional screw receptacles are used to accommodate the screws by means of which the substructure is usually attached to the window sash or the window gear in conventional window handle fittings.
  • the counterpart extends at least partially in the radial direction beyond the gear element.
  • Such an extension of the counterpart which is greater in the radial direction than the extension of the gear element, enables a simple implementation of the non-rotatable fastening of the counterpart to the window sash or the window gear.
  • Fastening interventions for the counterpart can be formed at a distance from the gear element in the radial direction.
  • the counterpart is designed separately from the gear element and, when the window sash is installed, can be inserted into the window sash independently of the window gear and connected to it or the window gear in a rotationally fixed manner.
  • a rotationally fixed connection to the window gear is to be understood as meaning that the counterpart is connected to the window gear in such a way that the gear element can rotate in the window gear and there is a relative movement between the counterpart and the gear element.
  • the counterpart is therefore non-rotatable with respect to the others Components of the window mechanism connected, but there can be a relative rotational movement between the counterpart and the transmission element.
  • the pusher element can be fastened in at least two axial positions on the torque transmission element in a rotationally fixed and axially captive manner.
  • the insertion depth of the torque transmission element can be determined independently of the design of the pusher element.
  • a pusher element can be used for torque transmission elements of different lengths or torque transmission elements inserted into the window sash at different depths. This makes the window handle fitting according to the invention particularly flexible and usable for a large number of applications.
  • the torque transmission element has at least one recess into which a pusher element-side projection can be brought into engagement, the pusher element being positively locked behind in the axial direction with the torque transmission element when the projection is in engagement with the recess.
  • the torque transmission element has at least two depressions in which the projection on the pusher element can be brought into engagement, each depression being assigned a different axial position of the pusher element relative to the torque transmission element.
  • the pusher element By engaging the projection in the various recesses on the torque transmission element, the pusher element can be fastened in different axial positions relative to the torque transmission element.
  • the projection on the pusher element side comprises a spring element, so that the projection is resiliently mounted in the radial direction.
  • the projection is resiliently mounted in the radial direction.
  • the projection can be braced in the radial direction into the depression or depressions by means of tensioning means, in particular a grub screw.
  • tensioning means in particular a grub screw.

  • the present invention also relates to a window sash which comprises a window handle fitting according to one or more of the embodiments just described.
  • FIG. 1 a window handle fitting according to the invention is provided with the reference numeral 10.
  • a window sash bears the reference number 12.
  • a pusher element 14 is arranged on the window sash.
  • the pusher element 14 has a neck section 16 and a handle section 18.
  • a window gear 20 is arranged in the interior of the window sash 12.
  • the window gear 20 comprises a gear element 22 designed as a gear nut for opening and closing a window which comprises the window sash 12 shown.
  • the gear element 22 is connected to the pusher element 14 via a torque transmission element 24 designed as a square element.
  • the torque transmission element 24 extends along an axial direction 26.

  • the counterpart 30 on the window gear side comprises a nut element 32, into which the screw 28 is screwed, and an encapsulation 34 made of plastic, which is non-detachably and non-rotatably connected to the nut element 32.
  • the counterpart 30 is non-rotatably connected to the window gear 20 via the extrusion coating 34.
  • the counterpart 30 on the encapsulation 34 has axial projections 36 which are shown in FIG Figure 2 can be clearly seen, which engage in corresponding recesses in the window mechanism 20.

  • the spring element 44 extends into a projection 46 on the pusher element side.
  • five depressions 48 Arranged on the torque transmission element 24 are five depressions 48, of which only one in each case bears a reference number in the figures. However, it is also conceivable to provide more or fewer depressions.
  • the torque transmission element 24 is preferred to provide with a multiplicity of depressions, so that there is great flexibility in what the The insertion depth of the pusher element is concerned, as a result of which the torque transmission element 24 and the pusher element 14 can be used in different window sashes without having to be adapted to the different dimensions of the window sashes.
