Description

The invention relates to a fitting for a window, a door or the like, with at least a first and a second fitting element and a coupling device by means of which the fitting elements are detachably connected to each other, wherein at least the first fitting element is a drive rod and the coupling device comprises a bolt, which is arranged transversely to the longitudinal extent of the drive rod inserted into a first recess of this and in a second recess of the second fitting element.

From the GB 2378981 a fitting is known, in which two connecting rod pieces are detachably connected together by means of a coupling device. The coupling device has a substantially plate-shaped connecting element, which is provided at the edge with a toothing and is inserted into a counter toothing of a recess of one of the drive rod pieces. On its underside, the connecting element has a pin which engages in an opening of the other drive rod piece. For laterally holding the two drive rod pieces to each other, a carriage is provided which is pushed onto the overlap region of the two drive rod pieces and at the same time covers the connecting element, so that this retains its insertion position. The assembly for connecting the two drive rod pieces is expensive and requires special components.

The invention has for its object to provide a fitting for a window, a door or the like, in which at least two fitting components are easily coupled and uncoupled in a very simple and inexpensive construction.

This object is achieved by a releasable locking seat for the bolt, wherein the locking seat has a locking spring which is resiliently deflected during the initial insertion of the bolt of this resiliently snapped and snap-fitted during further insertion of the bolt in a lateral locking recess of the bolt, whereby the in the two recesses inserted bolts is secured axially secured. For coupling the two fitting elements, it is therefore only necessary according to the invention to insert the bolt into its catching seat. Since the detent of the locking seat is solvable, can also be on simply remove the bolt again and thus decouple the two fitting elements. During insertion of the bolt, the locking spring is acted upon and elastically deflected so that it rests with bias on the bolt, so that they continue with the further insertion of the bolt, preferably in its final assembly in which he securely couples the two fitting elements together in the lateral locking recess the bolt snaps back springing. As a result, the bolt can no longer be moved counter to its insertion direction, in particular not move further in the insertion direction, but it is fixed axially secured and couples the two fitting elements by its engagement in the recesses. If a dismantling done, so the two fitting elements are to be decoupled from each other, it is only necessary to deflect the locking spring so far elastically that it no longer engages in the lateral locking recess of the bolt, whereby the bolt is released and pulled out of the recesses can. Thus, the two fitting elements are decoupled from each other.

The above-mentioned coupling device, which serves to couple the two fitting elements, has - as mentioned - the bolt. In addition, also include the two recesses and the locking spring of the coupling device, since these elements serve a simple and durable coupling, yet in the case of dismantling a decoupling is possible.

According to a development of the invention it is provided that the locking spring is arranged on the second fitting element, in particular held on the second fitting element. Preferably, it is held captive on the second fitting element, whereby the assembly work is facilitated.

It is advantageous if the locking spring is at least one radially deflectable to its longitudinal extent spring pin or has at least one such spring pin. The spring pin engages when securing the bolt with a portion of its longitudinal extent in the locking recess, which is accordingly designed as a locking groove. Preferably, the bolt has a longitudinal extent, wherein the longitudinal extension corresponds to its insertion direction. The blocking recess, in particular the locking groove, extends at least on one side of the bolt, namely transversely, in particular at right angles to its longitudinal extension. Accordingly, in the locking recess, in particular locking groove, engaging spring pin also extends transversely with respect to its longitudinal extent, in particular at right angles to the longitudinal extent of the Bolzens, wherein the spring pin laterally (with a side of him ahead), so not axially, snaps into the locking groove.

It is preferably provided that the locking spring is a hairpin spring. Accordingly, it is a U-shaped spring, wherein the two legs of the U each form a deflectable spring pin and are connected over an arc range, preferably 180 ° arc portion. The locking spring, in particular hairpin spring, is integrally formed. Due to the two spring pins of the hairpin spring they can engage on both sides of the bolt in there locking recesses, whereby the locking seat is improved.

A development of the invention provides that the second fitting element has a slot-shaped receptacle in which an end region of the drive rod and the locking spring are arranged. In the coupled position accordingly engages the end portion of the drive rod in the slot-shaped receptacle, that is, the two fitting elements are virtually put together. Subsequently, the bolt is inserted transversely to the longitudinal extent of the drive rod, in particular at right angles thereto, into the recess of the second fitting element and into the recess of the drive rod, thereby deflecting the locking spring, which preferably springs back into the locking recess upon reaching the insertion end position of the bolt and axially secures the bolt sets.

According to a development of the invention it is provided that the slot-shaped receptacle is formed between a first leg and a second leg of the second fitting element, wherein the distance between the two legs defines the width of the receptacle.

It is preferably provided that the drive rod has an upper side and a lower side, wherein the locking spring is located at the top or bottom and the sum of the thicknesses of the drive rod and the locking spring ≤ the width of the receptacle. The above statements apply to the coupled state of the two fitting elements. It follows that the inserted with its end into the receptacle drive rod between the locking element held on the second fitting element and the corresponding leg of the slot-shaped receptacle. Preferably, it is provided that the width of the recording minus the space for the arrangement of the locking spring leaves only such a wide space that the drive rod with little play in the slot-shaped receptacle can be used.

In particular, it is advantageous if the second recess is located on the first, the second or on the first and second legs of the second fitting element. The variant that the second recess is located on both legs of the second fitting element is preferred because then the bolt first through the part of the second recess on one of the two legs, then through the first recess of the drive rod and then through the part of the second recess on the other, the leg is pushed during coupling, which prevents, for example, in a drive of the second fitting element by means of the drive rod that a tilting moment is exerted on the bolt, since this is guided in its end regions respectively in the two legs and in its central region is loaded by the drive rod.

In particular, it is provided that the second recess is formed by a first opening penetrating the first leg and a second opening penetrating the second leg, wherein the two openings are aligned with one another.

Preferably, according to a further development of the invention, it is provided that the second leg emanates a web running transversely to its longitudinal extension, preferably in one piece, which is fastened to the first leg, wherein the two legs and the web together have a U-shape. The interior of the U forms the aforementioned slot-shaped receptacle for the end region of the drive rod.

A development of the invention provides that the locking spring is held on the web and / or the first leg.

As already mentioned, in a further embodiment of the invention, the locking spring formed as a hairpin spring on the bow portion, from the two ends of the spring pins go out in one piece.

A further embodiment of the invention provides that the web has a receiving recess for the bow portion of the hairpin spring.

For holding the locking spring is preferably provided that the web has a receiving recess for the arc portion of the hairpin spring. For holding the hairpin spring, it is also advantageous if the web has a projection which projects into the interior of the bow portion of the hairpin spring.

According to a development of the invention, it is provided that the web is riveted to the first leg of the second fitting element.

It is particularly advantageous if the bolt belongs to a bolt system having differently shaped, in particular different lengths, bolts, of which a bolt is selected and used in the fitting. The bolt system comprises various bolts, for example headed bolts, headless bolts and in particular bolts of various lengths. If just a coupling of the two fitting elements is to be carried out, then a correspondingly short bolt is used which does not or only slightly projects beyond the legs of the second fitting element. However, if a long bolt is used, such that it has a length that protrudes at least one of the legs in such a way that it forms a locking pin, then the bolt has a double function, on the one hand undertaking the coupling of the two fitting elements and, on the other hand, on the fitting forms a locking pin which can cooperate with a corresponding strike plate. The now serving as a locking pin bolt is for example on a sash of a window and the strike plate on a window frame of the window. If the locking pin displaced due to a displacement of the drive rod, so either a locking position of the sash on the frame or an unlocked position can be brought about. In this respect, it is particularly preferred that the bolt has a length protruding at least one of the legs in such a way that it forms a locking pin.

In particular, it is provided that the bolt has a shaft and a head. The shaft is used for insertion into the two recesses and he also has the locking recess for the locking spring. The head forms - in addition to the locking spring - an additional axial securing of the bolt and can also - in a long bolt, which forms a locking pin - represent the head of a mushroom-lock pin, such a mushroom-lock pin higher security of the fitting, for example in a Burglary attempt offers.

In principle, it is possible that the shaft and / or the head of the bolt has a circular cross-section. However, it is particularly preferred if the shaft and / or the head has / each have a rectangular or square cross-section.

Preferably, the two recesses are formed adapted in their layout to the cross section of the shaft. This means that in the case of a shaft which is circular in cross-section, the two recesses have a circular outline. In a rectangular or square cross-section of the shank, the two recesses in the plan are also rectangular or square designed.

A development of the invention provides that the bolt in two, rotated by 180 ° to each other lying positions or in four, each rotated by 90 ° to each other lying positions in the recesses can be inserted. The two, rotated by 180 ° to each other positions can be effected with a bolt whose shaft has a rectangular cross-section. The four, each rotated by 90 ° to each other lying positions of the bolt can be achieved if its shaft has a square cross-section.

The locking recess for receiving the locking spring is preferably a transverse to the longitudinal extension of the shaft locking groove. Preferably, the locking groove is formed on a plurality of sides of the shank, that is, in a rectangular or square cross-section of the shank, preferably on all four sides and in a shaft with a circular cross-section, preferably circumferentially around the shank.

A development of the invention provides that at least one side of the shaft is provided with a toothing, which meshes with a counter toothing of the first recess. Preferably, the first recess is formed as a slot extending in the direction of the longitudinal extension of the drive rod. Accordingly, the slot has a greater length than the thickness of the shaft, with the result that the drive rod on the second fitting element can be fixed in different axial positions, whereby the two fitting elements can be coupled in correspondingly different axial positions. This is particularly useful when fitting the window, door or the like during fitting, in order to adapt to the size of the window, door or the like, with the cutting and insertion of the first recess into the drive rod do not have to be very accurate, as can be done by an offset of teeth and counter toothing adjustment during assembly.

A further development of the invention provides that the head of the bolt projects far beyond the sides of the shaft. This has in particular in the possibility of mounting the bolt in one of the mentioned two rotated by 180 ° to each other lying positions or in one of said four rotated by 90 ° to each other lying positions the advantage that a corresponding head side of the bolt and thus a correspondingly large Overhang of the head side can be selected so that a corresponding contact pressure on a Counterelement, in particular the mentioned strike plate adjusts. By turning the bolt can thus adjust the contact pressure.

Furthermore, it is advantageous if at least one of the legs is penetrated by a tool insertion opening in order to effect an exemption of the locking spring. For disassembly, a tool, such as a blade of a screwdriver, can be inserted into the tool insertion opening, such that it deflects the locking spring, thereby releasing the locking recess of the bolt and the bolt can be pulled out.

In particular, it is provided that the tool insertion opening lies between the spring pins of the hairpin spring. This makes it possible to deflect both spring pins simultaneously by simply inserting the tool into the tool insertion opening, to release the bolt.

Finally, it is advantageous if the second fitting element is a corner drive. Consequently, the fitting consists of a drive rod and a corner drive, wherein the drive rod for actuating the corner drive is coupled thereto by means of the coupling device.

The invention further relates to a window, a door or the like, with a fitting, as explained above.
