The present invention relates to a fitting for windows, doors or the like, with a transmission which comprises:

• a gear housing,
• an input element which is rotatably mounted about an axis of rotation in the transmission housing and has a receptacle for an actuating mechanism connection element such as a square pin,
• an output element which is coupled or can be coupled to a drive rod and which can be driven to a displacement movement by rotating the input element, and a fixing element which, when the fitting is in the delivery state, is held on the one hand on the gear housing and on the other hand engages in a recess of the input element so that the input element is in to fix a predetermined rotational position, wherein the fixing element protrudes into the receptacle of the input element and can be detached from the gear housing to establish an operating state of the fitting by applying an actuating mechanism connection element to be inserted into the receptacle, and wherein the fixing element is tilted or pivoted from the gear housing is solvable.

Such fittings are used, for example, as so-called edge closures in rebate grooves of a door or window sash. To switch the fitting, e.g. for the purpose of locking or unlocking the sash with respect to a frame, the input element is rotated by means of an actuating element such as a handle. The transmission converts this rotary movement into a sliding movement of a drive rod, which in turn causes the sash to be locked or unlocked. In the simplest case, the rotary movement is converted into a sliding movement by means of an arrangement of a toothed wheel and rack. That is to say, the input element can be designed as a toothed wheel which meshes with a toothed rack that drives the drive rod.

In order for a fitting of the type mentioned to function properly, the components must be correctly positioned and, in particular, correctly positioned during assembly Rotational position of the input element are respected, which is time consuming and annoying.

The DE 82 03 945 U1 discloses an edge drive with a faceplate and an adjusting rod, which are releasably fixed in position to one another by a securing means. When the bevel gear is operated for the first time, the securing means is sheared off.

In the EP 1 536 086 A1 a door lock is disclosed in which, by inserting a lock cylinder, an elastic pivot lever can be moved out of a blocking engagement with a pinion.

The DE 33 27 899 A1 discloses an edge gear with a pinion that is secured against rotation in the delivery state. The pinion is secured against rotation by means of a safety slide, which is guided on the pinion so that it cannot be rotated. The safety slide has an extension which engages in a recess in the housing. When a square mandrel is inserted into the central recess of the pinion, the safety slide is pushed to the side, the extension slipping out of the recess and the anti-rotation lock being canceled.

The invention is based on the object of specifying a fitting of the type mentioned at the outset that is easier and quicker to assemble.

The object is achieved by a fitting with the features of claim 1.

According to the invention it is provided that the fixing element detached from the gear housing can be moved into the receptacle in a tilting or pivoting movement about a tilting axis due to the action of the actuating mechanism connection element.

The gear housing can in principle be a component of any shape or an arrangement of components which is designed for the rotatable mounting of the input element and can be fastened directly or indirectly to the window, door or the like. Due to the fixation of the input element in a defined rotational position, a fitter does not have to move the gear parts specifically into the correct position when hitting the fitting, so that assembly can take place much faster overall. The fitter does not have to worry about removing the fixation of the input element after assembly, since the connection between input element and gear housing is automatically released when the connection element is inserted - i.e. when the actuating mechanism is always connected. The predetermined rotational position can be a middle position in relation to the total stroke of the output element, especially in the case of tilt and turn fittings. A particular advantage of the invention is that the fixing element can be designed in a relatively simple manner and can accordingly be manufactured inexpensively.

The fixing element can be released from the gear housing by tilting or pivoting.

It is also provided that the fixing element released from the gear housing can be moved into the receptacle due to the action of the actuating mechanism connection element.

The fixing element detached from the gear housing can preferably be moved into the receptacle with clamping between an inner wall of the receptacle and an outer surface of the actuation mechanism connection element. By moving the fixing element into the receptacle, the fixing is released and the input element is now released for a rotary movement. At the same time, due to the jamming of the fixing element, the inevitably existing play of the actuating mechanism connection element in the receptacle is eliminated.

The fixing element can be moved into the receptacle in a tilting or pivoting movement about a tilting axis. As a result, when the actuating mechanism connection element is inserted into the receptacle, it comes out of engagement with the transmission housing particularly quickly.

The recess of the input element can be delimited in a direction that is axial with respect to the axis of rotation by a stop surface which forms an abutment for the fixing element with regard to the tilting or pivoting movement. When the actuating mechanism connection element is inserted into the receptacle, its front surface presses on the portion of the fixing element protruding into the receptacle, which, due to the stop surface, can only evade in a pivoting movement. As a result, the entire fixing element is pressed into the receptacle. If necessary, a recess for partially receiving the fixing element can be formed on the inner wall of the receptacle.

According to one embodiment of the invention, the fixing element is elongated, the longitudinal axis of the fixing element being oriented transversely to the axis of rotation in the delivery state of the fitting. An elongated fixing element oriented transversely to the axis of rotation is particularly well suited for connecting adjacent sections of the transmission housing and the input element. In particular, the fixing element can be designed as a simple rod or strip.

According to a special embodiment, the elongate fixing element has a first end and a second end, the first end being held on the transmission housing and the second end protruding into the receptacle of the input element.

One embodiment of the invention provides that the fixing element is designed as a separate part from the gear housing and, in the delivery state of the fitting, by engaging in a recess in the gear housing is held positively on the transmission housing. Such a separate fixing element can easily be moved within the recesses by acting upon it by the actuating mechanism connection element. Due to the positive fit acting in the direction of rotation, rotation of the input element is only possible by moving away or destroying the fixing element.

In order to release it from the gear housing, the fixing element can be moved into a release position in which it does not engage in the recess of the gear housing. Thus, the blockage of the input element can be lifted by simply moving the fixing element out of the recess of the gear housing. A shearing off or other destruction of the fixing element is not necessary in this embodiment.

The fixing element can be pivoted out of the recess of the gear housing for detachment from the gear housing.

The recess in the gearbox housing and the recess in the input element can each be opened to a side that is axial with respect to the axis of rotation, in order to enable the fixing element to be easily inserted during manufacture. The recess in the gear housing and the recess in the input element are preferably open to that axial side from which the actuating mechanism connecting element is inserted when the fitting is properly installed.

An alternative embodiment of the invention provides that, in the delivery state of the fitting, the fixing element is held cohesively on the gearbox housing, in particular with the fixing element being molded onto the gearbox housing. The gear housing, including the fixing element, could, for example, be manufactured as an inexpensive cast component. A loosening of the fixing element from the gear housing is z. B. possible by shearing off the fixing element as a result of a corresponding expenditure of force.

The fixing element can be elastically deformable. In this way, jamming or wedging of the fixing element between the receptacle and the actuating mechanism connection element can be supported. Even a slight expansion of the distance between the inner wall of the receptacle and the outer surface of the actuating mechanism connecting element after assembly can be compensated for by an elastic fixing element clamped in the relevant gap.

The fixing element can be made of plastic in order to enable simple and inexpensive manufacture.

According to a further embodiment, the fixing element has a rectangular, in particular square, cross-sectional shape. In particular, the fixing element can be designed as a simple rectangular bar. This enables cost-effective production and facilitates reception in a straight-walled recess.

The invention also relates to a gear unit of a fitting for windows, doors or the like, which comprises:

• a gear housing,
• an input element which is rotatably mounted about an axis of rotation in the gear housing and has a receptacle for an actuation mechanism connection element such as a square pin, and

According to the invention, such a gear unit comprises a fixing element which, in the delivery state of the gear unit, is held on the one hand on the gear housing and on the other hand engages in a recess of the input element in order to fix the input element in a predetermined rotational position, the fixing element protruding into the receptacle of the input element and for Establishing an operating state of the transmission unit can be released from the transmission housing by applying an actuating mechanism connecting element to be inserted into the receptacle.

The fixation of the input element in a defined rotational position, e.g. B. a middle position, allows quick and easy assembly of the associated fitting. The gear housing can have one or more coupling sections for a connection to further fittings or to a door or window sash.

In the Fig. 1 The gear unit 11 shown forms part of a fitting for windows, doors or the like and is specially designed for insertion into a recess in a rebate of a sash of a window, a door or the like. The transmission unit 11 comprises a transmission housing 13, which is designed in two parts here. An input element 15 of the gear unit 11 is rotatably mounted in the gear housing 13 about an axis of rotation R. A central passage of the input element 15 has a rectangular cross section and thus forms a receptacle 17 for an in Fig. 2-5 The square pin 19 shown. The square pin 19 is provided for connecting an actuating mechanism to the gear unit 11. For example, the square pin 19 can be coupled to an actuating handle or lever. It goes without saying that, in addition to a square pin 19, a large number of differently designed connection elements with a corresponding shape of the receptacle 17 are suitable for establishing a positive connection between an actuating element or another component of an actuating mechanism and the input element 15.

The output element of the transmission unit 11 is through an in Fig. 1-6 Not visible drive rail is formed, which is guided displaceably in the transmission housing 13 along its longitudinal axis L1 extending transversely to the axis of rotation R and can be coupled to a drive rod of the fitting. A special in Fig. 1 downwardly protruding from the gear housing 13 extension of the drive rail may be provided.

The displaceable drive rail is coupled to the input element 15 in such a way that it can be driven by rotating the input element 15 about the axis of rotation R to perform a displacement movement along its longitudinal axis L1. in the In the simplest case, the input element 15 can be designed for this purpose as a gearwheel or gearwheel segment which meshes with a toothed rack section arranged on the displaceable drive rail. A further drive rail can also be displaceably mounted in the gear housing 13, which can be driven using a deflection mechanism by rotating the input element 15 to a drive movement that is opposite to the other drive rail.

In the input element 15 there are formed two input element recesses 21 offset from one another by 90 ° with respect to the axis of rotation R, which are open both towards an axial front side 22 of the transmission housing 13 and towards the receptacle 17, but towards the opposite axial rear side 24 of the gear housing 13 are limited by a stop surface 23 ( Fig. 5 ). Furthermore, two housing recesses 25 offset from one another by 180 ° with respect to the axis of rotation R are formed in the gear housing 13, which are also open both to the axial front side 22 of the gear housing 13 and to the receptacle 17, but to the axial rear side 24 of the gear housing 13 are closed. When the input element 15 is as in Fig. 1 shown is in a predetermined central position or basic position, one of the input element recesses 21 is aligned with one of the housing recesses 25 in a radial direction with respect to the axis of rotation R. With an input element 15 rotated by 90 ° counterclockwise, the other of the input element recesses 21 and the housing recesses 25 would be aligned with one another. In this way, different hardware configurations can be taken into account.

To fix the rotational position of the input element 15 in a delivery state of the gear unit 11, a fixing element 27 in the form of an elastically deformable plastic part is provided, the dimensions of which are to be received in the input element recess 21 and the housing recess 25 are adapted. The fixing element 27 is specifically designed as an elongated rod with a square cross-sectional shape, although this shape is not mandatory.

During the manufacture of the gear unit 11, the fixing element 27 is inserted from the axial front side 22 along an insertion direction E into the recesses 21, 25 which are aligned with one another, until the in Fig. 2 delivery status shown has been reached. The longitudinal axis L2 of the fixing element 27 is aligned transversely to the axis of rotation R. Furthermore, the length of the fixing element 27 is selected such that it protrudes into the receptacle 17 in the delivery state, for example up to the center of the receptacle 17 close to the axis. The input element 15 and the gear housing 13 are positively connected to each other via the fixing element 27, so that the input element 15 is rotationally fixed in the middle position. This ensures that the input element 15 is correctly positioned for mounting the fitting when the gear unit 11 is in the delivery state.

When a square pin 19 is inserted into the receptacle 17 along the insertion direction E during the fitting assembly, it acts on the leg 29 of the fixing element 27 protruding into the receptacle 17 and pivots the fixing element 27 about a tilting axis S running at right angles to the axis of rotation R, as in FIG Fig. 3 can be seen. The stop surface 23 ( Fig. 5 ) forms an abutment for the fixing element 27 with regard to the pivoting movement. As the square pin 19 is further inserted, the pivoting process continues until the in Fig. 4 and 5 The operating state shown of the transmission unit 11 is reached. In this state, the longitudinal axis L2 of the fixing element 27 runs parallel to the axis of rotation R. Furthermore, the fixing element 27 is pivoted completely out of the housing recess 25. That is, the input element 15 is now released to rotate. As in particular in Fig. 5 can be seen, the fixing element 27 is largely in the receptacle 17 and is between a Inner wall 31 of the receptacle 17 and an outer surface 33 of the square pin 19 are clamped. Therefore, the coupling between the square pin 19 and the input element 15 is free of play.

While the in Fig. 1-5 The illustrated embodiment of a gear unit 11 according to the invention, the fixing element 27 is designed as a separate part from the gear housing 13 and is held positively on the gear housing 13 and on the input element 15 in the delivery state of the gear unit 11 Fig. 6 an alternative embodiment of a gear unit 11 'according to the invention, in which the fixing element 27' is held firmly on the gear housing 13 in the delivery state of the gear unit 11 '. In particular, the fixing element 27 ′ is cast directly onto the gear housing 13 here.

When the fixing element 27 'is acted upon by a square pin to be inserted into the receptacle 17, the fixing element 27' breaks at its end 35 on the housing side and thus detaches from the gear housing 13. The fixing element is then opened in a manner analogous to that described above with reference to Fig. 1-5 pivoted into the receptacle 17 as described.

The fixing element 27, 27 'not only enables a reliable central fixing of a gear unit 11, 11' or an associated fitting, but also ensures that the undesired play of the square pin 19 in the receptacle 17 is eliminated.
