[0001] Fitting on a sash or fixed frame of a window, door or the like

[0002] Description

[0003] The invention relates to a fitting on a sash or a fixed frame of a window, a door or the like, comprising at least one drive rod element which is movable in the longitudinal direction of the groove by means of a drive element which can be driven by an actuating device in a rebate groove provided with a groove base and a groove opening opposite thereto in a rebate surface on the sash or the fixed frame, wherein the drive connection of the drive rod element and the drive element is established via a coupling part which is connected to the drive rod element, wherein the coupling part consists of a base element and a joining element and the base element is arranged at least partially on the side of the drive rod element remote from the groove base and is movable with the latter in the longitudinal direction of the groove and carries the joining element.

[0004] Such a fitting is used for operating devices with a movable drive element, whereby the drive element and the operating device form a single unit. This allows for different fitting groove positions and sash overlap heights to be compensated.

[0005] DE 10 157 826 A1 discloses a fitting in which a drive rod section is inserted snugly into an undercut profile groove and an actuating device with a movable drive element is pivoted onto a coupling part consisting of a base element and a joining element in order to create a positive connection for longitudinal movement. The coupling allows only limited play in the longitudinal direction of the drive element and can therefore only be used for a small number of sashes and frames. FR 2 722 527 A1 discloses a fitting in which an actuating device has two drive elements that can be moved in opposite directions and each engages a coupling part that is arranged integrally on a drive rod section. The drive elements have a round outer shape and the coupling parts have a continuous, open, rectangular recess.The coupling parts are not adjustable and are positively coupled to further connecting rod sections.

[0006] The invention is based on the problem of developing a fitting of the type mentioned at the outset in such a way that it is very versatile and allows the more frequent use of standardized operating devices and enables particularly simple assembly and adjustability.

[0007] This problem is solved according to the invention in that the joining element can be arranged in several positions offset from the base element in the transverse direction of the groove.

[0008] This design allows for easy compensation of different fitting groove positions and sash overlap heights. Actuators with a standard-length drive element can be used much more frequently, resulting in significantly more versatile fittings.

[0009] The joining element can be installed and adjusted easily and safely both during initial installation and when adjusted on the installed window if the joining element can be arranged on the side of the base element facing away from the drive rod element using several connecting elements. This also enables the easy use of an operating device with a drive element of a different length on the installed window. The joining element installation is further simplified if the connecting elements are tenon-hole connections and screw connections. The tenon-hole connections also serve as pre-fixing during installation, and the screw connections as additional security. These two different connection types ensure not only simple installation but also secure, permanent fixation. All connecting elements can transmit high forces thanks to the form-fitting connections.

[0010] The joining element can be easily positioned at a specific distance from the base element if the tenons of the tenon-hole joints each have a wider diameter base tenon and a shoulder with an adjoining smaller diameter plug-in tenon with a free end for receiving the joining element. This ensures that the joining element rests securely on the shoulder when assembled.

[0011] A further advantageous development allows the joining element to be particularly easily arranged in several positions offset from the base element in the transverse direction of the groove if it is constructed symmetrically around a central transverse axis and the connecting elements for connecting to the base element are arranged on an axis offset parallel to a longitudinal central axis by a distance. Due to this off-center position of the connecting elements and the symmetry of the joining element around the central transverse axis, a simple rotation of the joining element by 180° allows the joining element to be offset in the transverse direction of the groove. The connecting elements are swapped by this rotation.

[0012] The joining element is particularly easy to handle when it has a U-shaped cross-section. The connecting elements for connecting to the base element are arranged on a central web arranged longitudinally to the base element, and webs protruding from the central web extend toward the rebate surface. This design enables a compact design of the coupling part and thus its installation in the spatially limited rebate space between the frame and the sash. Furthermore, the joining element can be easily grasped by hand, and its position can be adjusted as needed.

[0013] Versatility and the improved possibility of using standardized operating devices are enhanced if the webs each have a transversely aligned recess for the drive element. This allows the drive element driven by an operating device to have very different lengths and easily compensate for different fitting groove positions and sash overlap heights. It is sufficient if the drive element engages at least in the recess of one web.

[0014] The joining element can be easily rotated 180° for adjustment if the central transverse axis is aligned with the center of the recesses. Due to this symmetrical arrangement, longitudinal displacement of the actuating device for coupling with the drive element is not necessary when the joining element is rotated 180°. The drive element can thus penetrate the recesses of both webs and protrude from the joining element with its free end. This makes the coupling part extremely versatile when used in conjunction with standardized actuating devices.

[0015] The longitudinally movable drive rod element is particularly well protected against wear if a faceplate that largely closes the groove opening is arranged in the rebate groove and the faceplate has at least one recess that enables the movement of the base element in the longitudinal direction of the groove.

[0016] A further advantageous development of the invention makes the base element particularly stable if the base element, in the area protruding from the groove opening, extends beyond the recess on both longitudinal sides. The sides of the base element that overlap the recess serve as additional guide elements during longitudinal movement and provide additional stability by supporting the faceplate in the event of a potential tilting of the coupling part. The tilting tendency of the coupling part can be caused, for example, by a high force acting on the actuating device. These forces can thus be safely dissipated via the faceplate in any position.

[0017] The coupling part can also be used in particularly tight installation situations in the rebate area, provided the joining element does not protrude beyond the faceplate on one long side. The joining element, as the widest component of the coupling part, therefore protrudes neither beyond the faceplate nor the groove opening on one side. Therefore, the coupling part can also be used when the groove opening is located very close to the edge of the sash or frame-side rebate surface, for example. This is usually the case on sashes with a small groove. The groove position refers to the distance between the groove center and the seal on the sash overlap.

[0018] A further advantageous development of the invention allows the joining element to be mounted and adjusted particularly easily and securely if at least one screw receptacle for the screw connection arranged on the central web of the joining element has a countersunk pressure, and the countersunk pressure is supported on a support surface of the base element, and the tenon-hole connection and screw connection together support the joining element on the base element. This additional support surface also increases the stability of the coupling part. It is particularly advantageous if the tenon-hole connections and screw connections are arranged close to the recesses for the drive element. Ideally, a tenon-hole connection and a screw connection are arranged close to both ends of the recesses.

[0019] The invention permits numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and is described below. This shows in
