Description

The invention relates to a latching module for window and / or door fittings, comprising a housing having a circular receiving opening and a rotatably mounted therein rotor element with a polygonal receptacle for receiving a polygonal mandrel of a control handle and a mounting base having handle module, and with between the housing and the locking element acting on the rotor element, wherein the locking module is designed as a separate unit with respect to the handle module and with a fitting-side gear unit with the handle module via the multi-edged pin engageable in the polygonal receptacle is positively connected.

Such locking modules are used to make the angular orientation of window and / or door handles for certain functional positions of the fitting for the end user felt and possibly audible and thus facilitate the intuitive operation of the window and / or the door.

A locking module of the type mentioned is from the EP 0 881 344 A2 known. The locking module is screwed to the operating handle via a stud screw. The locking module is then screwed to the window or door.

From the DE 94 04 851 a handle module is known, which within the associated with the operating handle mounting base, which is used for connection to a sash, has an integrated locking device. This locking device has a revolving rotor element, engage in the housing attached to the locking means and thus facilitate the achievement and determination of defined functional positions of the operating handle for the user. By accommodating the locking device within the mounting base, the size of the mounting base can not fall below a certain minimum because of the space requirements.

An important aspect for the end user in the case of operating handles is their optical design. Not all control handles are equipped with locking devices. A retrofittability is not always possible due to the respective different mounting base plates and the respective different related surface materials. With operating handles with existing detent positions, these do not always match the functional positions specified by a drive rod fitting of the window or the door. This occurs, for example, when handle modules have three detent positions spaced at right angles and a predetermined by the espagnolette gap ventilation position, which is arranged between two locking positions has. A retrofittability would be possible, if at all, only by an exchange of the entire handle module.

The invention has the object of providing a locking module of the type mentioned in such a way that a simple retrofitting is made possible to any operating handles. In addition, should be possible to retrofit additional detent positions on control handles, which already have detent positions.

To achieve this object, it is provided that the locking module is provided for mounting between the mounting base and a fitting-side gear unit and that the housing on its side facing the handle module fixing wedges for fixing the position relative to the sash. The design as a separate unit allows both easy retrofitting to handle modules that have no locking positions, as well as to handle modules that already have handle positions. In this case, the otherwise unused space between the handle module and the fitting-side gear unit is used to accommodate the locking module. It is only the already existing opening through which the polygonal mandrel is guided to the gear unit, possibly to increase something.

In a further development of the invention is provided according to claim 2 that the housing resiliently arranged locking cams are arranged, which can be latched into latching recesses of the rotor element and thus form the latching means. By using separate, not integrally connected to the housing, resilient locking cams and the associated easy interchangeability easy adaptation to different requirements of the locking means is ensured.

In a further embodiment of the invention is provided according to claim 3, that the housing has a substantially cylindrical outer contour and can be inserted into a correspondingly designed with this cylindrical receiving opening of a sash. The opening on the casement, through which the polygonal mandrel is guided to the gear unit, and in which the locking module is housed must, as already stated above with respect to the normally present opening size under Circumstances are increased. Due to the cylindrical outer contour, this enlargement is possible with a simple drilling or milling tool with a rectilinear dipping motion, without the possibility of achieving complicated opening geometries.

In a further development of the invention is provided according to claim 4, that the slopes of the fixing wedges are designed such that a positional fixation takes place by self-locking clamping between the housing and the sash. By clamping the housing with fixing wedges a simple attachment to the sash is guaranteed, which is possible without additional components by simply plugging the locking module into the cylindrical receiving opening of the sash by simply plugging.

In a further embodiment of the invention is provided according to claim 5, 6 and 7, that the locking cams are part of an approximately U-shaped bent wire portion which is fixable with its wire-section base in a wire section receiving channel of the housing, wherein the end portions wire section legs form the locking cams, wherein the locking cams are angled approximately c-shaped inwardly with respect to the wire section legs, and wherein the wire section having the locking cams is arranged on the side of the housing opposite the fixing wedges. The wire section offers the advantage that with him both the resilient function can be achieved by the elastic properties of the material and the locking function by the molded locking cams with a single component.

In a further embodiment of the invention is provided according to claim 8, that four locking positions by the locking means are formed, three of which are each spaced by about 90 ° from each other and the fourth detent position is located bisectronally between the first and second detent position. With this embodiment, the locking module is provided primarily for handle modules without any detent positions.

In a further development of the invention is provided according to claim 9, that at least one detent position is formed by the latching means, which thus forms an additional detent position to existing locking positions of the handle module. For a simple extension of the number of locking positions for already equipped with locking positions handle modules is possible.

In a further embodiment of the invention is provided according to claim 10, that the number of locking positions of the locking module by using a suitably designed rotor element, wherein the number of locking position on the number of locking recesses in the rotor element is determined. Thus, the latching characteristic of the latching module can be adapted with little effort by simply replacing the rotor element.

Fig. 1 shows a portion of a sash 10, which may be part of a door or window, not shown. In the sash 10 is schematic indicated drive rod fitting 12 visible to which a transmission unit 14 belongs. A handle module 16 can be used with a polygonal mandrel 18 in a polygonal receptacle of the gear unit 14, not shown, whereby a rotation transmission from the polygonal mandrel 18 takes place on the gear unit 14 and thus on the espagnolette 12. The handle module 16 consists of a mounting base 20, which serves to connect to the casement 10, and a control handle 22, which serves to drive the polygonal mandrel 18. Between the handle module 16 and the gear unit 14, a latching module 24 is shown, which represents an independent module with respect to the other components.

The locking module 24 consists, as in FIGS. 2 and 3 shown, of a housing 26 and a rotatably mounted in a circular receiving opening 30 rotor element 28. The rotor element 28 has on its peripheral surface locking recesses 32, which are part of locking means which define certain detent positions between the housing 26 and the rotor member 28. On the housing resiliently arranged locking cams 34 are arranged, which can be latched into the latching recesses 32 and thus form the latching means. The locking cams 34 are angled approximately c-shaped with respect to the wire section, wherein their shape is formed corresponding to the shape of the detent recesses.

The outer contour of the housing 26 is cylindrical and formed corresponding to a receiving opening 36 of the sash 10. On the handle module 16 side facing fixing wedges 38 are arranged on the housing 26. By inserting the housing 26 into the receiving opening 36, the material is deformed in the region of the fixing wedges and ensures the fixing effected by the bias.

In the FIGS. 2 and 3 embodiment shown achieved by the two detent recesses 32 and the two locking lugs 34, which are respectively arranged in the same direction, a detent position and is therefore primarily intended as a retrofit component for handle modules that already have detent positions and for certain operating positions more detent positions are required. By replacing the rotor element 28 in a correspondingly on the peripheral surface a plurality of oppositely arranged locking recesses 32 correspondingly a plurality of locking positions could be realized.

For mounting the locking module 24 on the casement this is first inserted into the receiving opening 36, wherein a fixation-proof and rotationally fixed fixing takes place by the fixing wedges 38. In a corresponding orientation of the locking module, according to the later desired locking positions, it is important to pay attention. If necessary, the receiving opening must be enlarged beforehand. The locking module is located in the installed state substantially within the sash. Subsequently, the handle module 16 is placed, wherein initially the polygonal mandrel 18 is inserted into the locking module polygonal receptacle 40 of the locking module and then pushed to the sash and is screwed to it. The polygonal mandrel is thereby pushed through the locking module polygonal receptacle 40 and comes to rest within the polygonal receptacle of the gear unit 14, not shown. Therefore, there is a direct power transmission from the polygonal mandrel 18 to the gear unit 14. The locking module 24 therefore has no share of the power transmission between the handle module and the gear unit 14. Upon rotation of the polygonal mandrel 18, the rotor element 28 is also rotated accordingly. That through the fixing wedges rotatable housing and the associated locking cam 34 remain stationary relative to the sash 10. By locking the locking cam 34 with the detent recesses 32, it comes to the desired locking. The latching can be overcome by a slightly increased introduction of force, while the locking cams move elastically outwards. Thus, the purpose is achieved that the user recognizes certain angular positions of the operating handle as functional positions during the rotational movement of the operating handle by easily noticeable, but also surmountable detent positions, thereby improving the overall intuitive operation of the window or the door.
