Description

The invention relates to a fitting for windows, Doors or the like, with one on the casement, Door leaf or the like rosette to be attached and a handle rotatably mounted thereon, the a different closed positions Locking device is assigned, the bolt for Taking the different closed positions in parallel is displaceable to the axis of rotation of the handle and itself when the handle is actuated in a coaxial to the axis of rotation of the handle Movement path moved.

Such a fitting is known from EP 0 763 638 A1 known, and suitable for a window sash in to transfer a closed, tilted or rotary position. According to the desired position of the window or door leaf, the handle is in each case Can be turned 90 °. Depending on whether right or left flapping wings are present is a rotary motion the handle in 90 ° steps in or opposite clockwise necessary. through of the different closed positions Locking device can be an actuation path Handle to be limited so that unauthorized transfer of the wing with the fitting in the tilt and / or rotation position is not possible. The fitting known from EP 0 763 638 A1 has for this purpose a coupling consisting of two ring elements according to the desired closed position are rotatable to each other. One of the Ring elements is axial through the locking device movable and rotatable by the handle stored and forms a bolt of the locking device out. The other ring element is non-rotatable attached to the rosette of the fitting. Next to the - complicated due to the large number of individual elements Construction is disadvantageous in the known fitting, that for use on a left or to dismantle the right wing is and that the rotatable with the rosette connected ring element changed in position must become.

EP-A-0 752 509 relates to an operating handle for windows, doors or the like, a bolt has a radial extension with a stop interacts, which on the rosette as Toothing is formed. The toothing is an integral part the rosette.

The invention has for its object a fitting of the generic type to create the is simple and in a simple way a use for both left and right striking Wings allowed.

According to the invention, this task is carried out with a fitting with the features mentioned in claim 1 solved. The fact that the bolt in at least one of the closed positions with a corresponding to the Operation of the handle is limited in rotation Rosette associated stop cooperates, lets the stop without it being in its installation position needs to be changed, both for left as well as for the right wing. The rotational mobility of the stop ensures that that this corresponds to the im or can be operated counterclockwise Handle is twisted to a limited extent, so that despite Use one and the same stop an actuation the handle by 180 °, both in and also possible counter-clockwise is. Due to the rotatability of the stop thus the path of movement of the handle by each 180 ° not limited, because of this Dodge rotation accordingly.

In a preferred embodiment of the invention, that the stop is limited in rotation the rosette is mounted, in particular the Rosette a guide bush for the storage of the Has handle that simultaneously storage of the attack. This makes it easier to do Achieve a centered positioning of the stop, this preferably being designed as an annular body, and limitedly rotatable around the guide bush is stored. Here is preferred an inner diameter of the ring body an outer diameter the guide bush adjusted so that an essentially play-free rotary movement is possible is. The stop designed as a ring body is easily available as a machine part, so that the entire fitting is covered by a particularly simple, robust and therefore reliable Structure distinguished.

In a further preferred embodiment of the invention it is provided that the stop in a guide bushing encompassing annular groove of the rosette is, the annular groove preferably two diametrically opposite locks to limit the Has rotary movement of the stop. By the additional Guiding the ring body in the ring groove is a particularly reliable function of the limited guaranteed rotating stop. By engaging the ring body in the ring groove this is both on its inner surface through the guide bush and its outer surface passed through the ring groove. It is also preferred that the locks of themselves over an angular range, extending preferably from 20 ° to 60 ° Pedestals are formed to which the ring body with protrudes into the annular groove. The protrusions extend over one Angular range of preferably 20 ° to 60 °, wherein the angular extent of the projections on the angular extent the pedestals are coordinated that the defined limited rotational mobility of the Stop is guaranteed. Through training the platform and the protrusions become relatively stable and created solid stops, which one too withstand relatively large forces and thus are safe.

In Figure 1 is a total of 10 Fitting for a window, a door or the like shown. The fitting 10 comprises a handle 12, a handle neck 14 and a handle 16 having. The handle 12 has a receptacle 18, in the one designed as a lock cylinder 20 Locking device 22 can be used. The locking device 22 is known to be with one here Actuating means, not shown, for example one key, in three locking positions transferable. According to the closed positions of the Locking device 22 becomes a locking pin 24 axially displaced. The locking bolt 24 carries one Bolt 26, which corresponds to the closed position of the Closing device 22 can thus also be moved axially is.

The fitting 10 also includes a rosette 28, the by means of fasteners, not shown here on a window sash, door sash or the like is attachable. The rosette 28 forms the Wing facing side a cavity in the a drive pin 30 of the fitting 10 engages. On his protruding into the cavity of the rosette 28 The end 32 of the drive pin 30 has a rotationally fixed arranged gear 34, which is in active engagement with at least one slide, not shown stands. The slide is on the side of a through opening 36 of a guide bush 38 is arranged. The Slider has a rack that connects to the gear 34 combs. For the explanation of the embodiment it is assumed that a slider -in Top view of rosette 28 viewed on the right the through opening 36 is arranged. The drive pin 30 is facing away from the gear 34 End 40 through the through opening 36 feasible and reaches into a pocket opening in the handle neck 14 a. Via a polygon arrangement 42 the drive pin 30 is non-rotatable with the handle 12 connected.

The fitting 10 further comprises a stop 44, which is formed by an annular body 46. This has an inside diameter that is substantially an outer diameter of the guide bush 38 equivalent. As a result, the ring body 46 is over the guide bush 38 feasible, an inner Shell surface 48 of the ring body 46 on an outer Shell surface 50 of the guide bush 38 essentially is free of play.

The detailed structure of the stop 44 is based on of Figure 2 explained in more detail. The guide bush 38 is in the rosette 28 encircled recessed annular groove 52. A breadth of Annular groove 52 is selected so that the annular body 46 in the annular groove 52 engages and with its outer Shell surface 54 essentially free of play on one The outer surface 56 of the annular groove 52 bears. Within the annular groove 52 are opposite two as platforms 58 trained locks 60 mirror image Guide bush 38 arranged (in Figure 1 is only the front platform 58 visible). The platforms 58 extend over an angular range α, which is between Can be 20 ° and 90 °. In the example shown the angle α is 70 °. Form the platforms 58 each have a guide surface 62 for the ring body 46 from the end face 64 on the Guide surfaces 62 rests. The platforms 58 have a smaller height than the annular groove 52, so that in the area of the platforms 58 a contact area between the lateral surface 54 of the ring body 46 and the outer surface 56 of the annular groove 52 remains.

From the annular groove 52 arise in mirror image to Guide bush 38 arranged pockets 66. A die Pockets 66 imaginary radial dividing symmetrically runs offset by 90 ° to one of the platforms 58 imaginary radial dividing symmetrically. The bags 66 are axially aligned in their shape Extension 70 of the bolt 26 adapted.

The stop 44 has the perspective view View in Figure 2 structure explained in more detail. Arise from the annular body 46 in the direction of the annular groove 52 projections 72 arranged in mirror image. The projections 72 are designed like a ring segment and extend over an angle β, for example is between 20 ° and 60 °. In the shown For example, the angle β is approximately 40 °. The projections 72 have a height so that they into the annular groove 52 - on the guide surfaces 62 the pedestals 58 of the end face 64 of the Intervene in the ring body 46-. The protrusions form here 72 radial and axial end faces 74 or 74 '. The end faces 74 and 74 'of a projection 72 are corresponding here the size of the angle β spaced apart arranged and run on radial an axis of rotation 68 of the handle 12. The projections 72 are arranged here in mirror image, that the end faces 74 or the end faces 74 'each on one through the axis of rotation 68 thought radial radials. The end faces 74 of the projections 72 are in each case radially and axially extending end faces 76 of the Platforms 58 and the end faces 74 'of the projections 72 radially and axially extending end faces 76 ' the platform 58 facing (Figure 1).

The stop 44 also has second projections 78, opposed by the ring body 46 in the axial direction spring to the protrusions 72. The Projections 78 are mirror images of the guide bush 38, one of the projections 78 symmetrical dividing radial to the axis of rotation 68 um 90 ° to a symmetrically dividing the projections 72 Radials is offset. Form the projections 78 Levels 80 and 80 'respectively. Hereby comes it for the formation of axially and radially extending End faces 82 and 84 or 82 'and 84 ', each over a radially extending surface 86 and 86 'merge. The end faces 82 and 84 and the end faces 82 ' and 84 'of the two projections 78 run here each on a radial intersecting the axis of rotation 68. The end faces 82 and 82 'of each other protrusions 78 located opposite each other via a radial end face 88 of the ring body 46 into each other. While the end faces 84 and 84 'each of a projection 78 over a radial End face 90 merge.

The latch 26 is designed so that its the stop 44 facing surface 92 on a circular line extends around the axis of rotation 68 and with the lateral surface 50 of the guide bush 38 coincides. A surface 94 of the extension facing the stop 44 70 of the bolt 26 runs on a circular line Axis of rotation 68, which with the outer surface 54 of the ring body 46 coincides.

The fitting 10 shows the following functions:

In the assembled state of the fitting 10 is the Ring body 46 guided by the guide bush 38 and lies with its end face 64 on the guide surfaces 62 of the platforms 58. The protrusions 72 engage in the annular groove 52. The drive pin 30 is through the through opening 36 of the guide bush 38 inserted and non-positive with the handle 12 connected. The locking device 22 is locked in the receptacle 18 of the handle 12, so that the bolt connected to the locking bolt 24 26 is arranged on the side of the guide bush 38. The exact position of the bolt 26 depends on the one hand after the position of the handle 12 and the Position of the locking device 22. To the possible To clarify positions of bolt 26, reference is made to Figures 3 to 6. There is the fitting 10 each in a schematic Partial view shown, the same parts as in the Figures 1 and 2 provided with the same reference numerals and are not explained again.

In order to clarify the possible positions of the handle 12, is in the plan view shown in Figure 6 on the rosette 28 a radial 96 Axis of rotation 68 entered, according to the plan view on the left a position of 0 ° and according to Top view on the right assumes a position of 180 ° becomes. As is known, the handle 12 of the fitting 10 from a closed position at 0 ° in a first actuation position at 90 ° and a second operating position can be transferred at 180 °. Assuming vertical installation on a window or door leaf, the fitting 10 is oriented that the 0 ° position below and the 180 ° position above is. Depending on whether it is a right or left wing is the 90 ° position -According to the top view in Figure 6- below or above, on the window sash on the right or left. In the further explanation it is assumed that the fitting 10 is a so-called Tilt-First fitting deals, that is, in the wing is locked in the 0 ° position The wing is in the 90 ° position in the tilted position and in the 180 ° position is the sash in the rotating position brought. After further, not explained in more detail Exemplary embodiments, the fitting 10 can of course be designed so that, for example one position at 90 ° and one at 180 ° Tilting of the wing is possible.

First, a fitting 10 for one wing on the right, that is, the fitting 10 is on the left side of the wing arranged. The fitting 10 is with its rosette 28 attached to the wing, the one with the gear 34 engaged slider in operative connection with a lifting rod arranged in the wing stands. According to the rotation of the gear 34 the slide is moved translationally, so that the lifting linkage follows this movement and locking wedges of the wing changed their position. In the 0 ° position of the handle 12 is the Sash closed and locked, in the 90 ° position the handle 12 is the wing in the tilt position and in the 180 ° position the wing is in the rotary position bringable, the handle 12 counter rotatable clockwise about the axis of rotation 68 is. The release of the individual actuation positions the handle 12 takes place via the locking device 22. According to a rotation of the Closing mechanism of the locking device 22 is the bolt 26 is displaced parallel to the axis of rotation 68.

Without restricting the operating function of the fitting 10 is the bolt 26 in his axially uppermost position shown in Figure 3. Corresponding the rotation of the handle 12 becomes the entire Locking device 22 and thus bolt 26 moved coaxially to the axis of rotation 68. By the axial The topmost position can be the latch 26 on the end face 84 'of the front in FIG. 3 and in FIG. 6 lower projection 78 are passed without that the stop 44 in the coaxial trajectory of the latch 26 lies. This allows the handle 12 from its 0 ° position, over the 90 ° position in the 180 ° position are transferred so that all Operating positions of the wing are possible. Limiting the rotational movement of the handle 12 constructive beyond the 180 ° position by engaging with the wing's linkage standing slide of the fitting 10.

Should reach the actuation position at 180 ° the handle 12 are prevented, is the locking device 22 in its in Figure 4 shown closed position brought. By pressing the locking device 22, for example turning an actuating means (key) of the locking device 22, the bolt 26 is parallel to Axis of rotation 68 shifts and takes its in Figure 4 shown position. As a result, the bar is in place 26 at the same axial height as the end faces 84 or 84 'of the stop 44. When twisted the handle 12 from its 0 ° position in its 90 ° position, the bolt 26 is coaxial with Axis of rotation 68 moves and strikes the end face 84 'of the front in Figure 4 and in Figure 6 below projection 78 shown. According to the Position of the platforms 58 and the projections 72 (FIG. 1) the stop 44 corresponding to the rotational movement of the bolt 26 carried until the end faces 74th of the projection 72 on the end faces 76 of the platforms Strike 58. The angles α of the platforms 58 and the angles β of the projections 72 are now chosen so that when the end faces 74 on the End faces 76 the handle 12 in its 90 ° position located. This will make one of the 90 ° position corresponding actuation of the fitting 10 having wing possible. A further turning of the Handle 12 to the 180 ° position is by the Stop 44 prevented because this is limited rotatable up to the explained stop on the Podiums 58 can be moved.

In the closed position shown in Figure 4 can the handle 12 again without impairment in the 0 ° position can be turned back so that the wing brought into its closed position and locked can be. In that the stop 44th only in its counterclockwise direction Rotation (in the example of the right striking wing) positively guided by the bolt 26 is, the stop 44 remains in its Position.

Should the handle 12 not be transferred to any of the Actuation positions will be possible Locking device 22 into that shown in FIG Closed position transferred. By turning on of the actuating means (key) of the locking device 22, the bolt 26 is further parallel shifted to the axis of rotation 68, so that in the 0 ° position the handle 12 the extension 70 of the bolt 26th engages in the pocket 66 shown on the left in FIG. 6. This will cause the handle to twist 12 prevented from their 0 ° position. The fitting 10 wings has thus neither tilt nor rotatable.

The fitting 10 explained in FIGS. 1 to 6 can now be done without any manipulation and / or replacement of individual parts of the fitting 10 or a dismantling of the fitting 10 requiring Repositioning of individual parts also for left hinged wings are used. For this purpose, the fitting 10 is only with its rosette 28 on the right side of the wing assemble. For this purpose, the handle 12 and the rosette 28 to rotate by 180 ° relative to each other. The locking device 22 is in this in Figure 3 brought position, so that the latch 26 on the end faces 90 of the stop 44 can be moved past. The one arranged in the rosette 28 Slider is thus on the other side of the Through opening 36 shifts and takes its mounting position in terms of the lifting linkage of the now left wing. According to the then the mounting position is the handle 12 can be turned clockwise from the 0 ° position. The 180 ° position shown in FIG. 6 then corresponds to the 0 ° position of the left flapped wing. The individual closed positions correspond in turn to the locking device 22 those shown in Figures 3 to 5 Closed positions, after which the bolt 26 accordingly the closed position of the locking device 22 is displaceable parallel to the axis of rotation 68. In the closed position shown in Figure 3 the handle 12 can in turn be rotated through a total of 180 °, the operating positions of the wing in the 90 ° position and 180 ° position.

Should the 180 ° position be reached by the Handle 12 are prevented, the locking device 22 in the closed position shown in Figure 4 transferred. As a result, the bolt 26 is in turn at the same level with the end faces 84 or 84 'of the projections 78. By now clockwise direction of actuation the handle 12, the latch 26 against the end face 84 of the bottom in FIG. 6 or in Figure 4 led front projection 78. This is limited due to its rotatable Bearing on the guide bush 38 can be rotated so far, until the end faces 74 'of the projections 72 of the Stop 44 on the end faces 76 'of the platforms Strike 58. Thus, the stop 44 on one further clockwise rotation prevented. By the on the end face 84 of the projection 78th striking bolt 26, bolt 26 also becomes prevented from turning further, so that the handle 12 can only be moved into their 90 ° position is.

Of course, the one shown in FIG. 5 is also shown Closed position of the locking device 22 achievable, this closed position of the Locking device 22 and thus the locking of the Handle 10 is identical to the closed position or locking the handle 12 in the previously explained example of one on the right Wing. The extension 70 then engages in the pocket 66 shown on the right (FIG. 6).

In addition to the explained uses of the fitting 10 there is also the possibility of this on the right as well as left wing hinged, where the 180 ° position (Figure 6) is the starting position and thus the closed position of the wing is. Due to the mirror-symmetrical design, both the annular groove 52 and the stop 44 is by simply turning the handle 12 through 180 ° and subsequent installation of the fitting 10 on Wing this again for right-hinged or left hinged or if necessary, posted below or above Wings can be used. Any conversions and / or replacement of individual components of the fitting 10 are not required.

Overall, it is clear that the fitting 10 universal in spite of its simple and robust construction can be used. Especially when used as the so-called tilt-first fitting can be used almost any window, door leaf or the like assemble, according to the closed position the locking device 22 individual actuation positions the handle 12 blocked or are released.
