Description

The invention relates to a rotary device for window and door handles, with a housing and a clamping device for fastening the housing to a wall of a hollow profile and with a polygonal receptacle for a polygonal pin of the window or door handle, with a polygonal pin of the window or or door handle interacting locking mechanism is provided, with which the window or door handle can be adjusted in a locking manner in predetermined angular steps corresponding to different functional positions, the clamping device having at least two clamping lugs which can be actuated by means of screws and which in an assembled position protrude slightly beyond the housing and in a fastening position on a Abut the inside of the wall of the hollow profile and achieve a clamping effect with a housing flange arranged on the outside of the wall of the hollow profile.

Such rotary devices are used, for example, to actuate a gear mechanism with which a window or a door can be brought from a closed position into a tilted position or pivoted position. In order to fasten the rotating device to a window or door frame profile, it is known to provide two lateral brackets with screw openings on the rotating device. Due to the side arms, the rotating device looks quite massive. However, a visually unobtrusive rotating device is often desired. In addition, in certain applications there is a need to be able to lock the window or door handle for actuating the rotary device in one or more rotary positions, for example to only allow the window or door to be tilted but not swung open.

A generic rotary device is from DE 20 2015 101 329 U1 famous. However, the installation of this rotary device in a hollow profile is comparatively cumbersome. Another rotary device is from the EP 2 476 823 A2 famous.

Proceeding from this, the object of the present invention is to create a rotary device of the type mentioned which is as compact as possible and which can be easily mounted on a wall of a hollow profile.

To solve this problem, the combination of features specified in claim 1 is proposed. Advantageous refinements and developments of the invention result from the dependent claims. According to the invention, the clamping lugs are held in the assembly position with a removable securing element in the housing.

In a preferred embodiment of the invention, the securing element is designed as a spring element that can be slipped onto the housing transversely to the polygonal receptacle. Alternatively, the securing element can be designed as a positioning part that can be slipped onto the housing axially via the polygonal receptacle.

In a further preferred embodiment of the invention, the housing has an essentially circular mounting surface, the mounting surface having at least one radially protruding projection which, together with a complementary milled opening in the wall of the hollow profile, forms an anti-twist device for the housing, the milled opening being inserted when it is inserted of the housing allows the slightly radially protruding clamping lug to pass through.

In a further preferred embodiment of the invention, the latching mechanism has two spring plates acting on mutually opposite side surfaces of the polygonal receptacle of the window or door handle. Alternatively, the latching mechanism can have a shaped spring plate acting on two adjacent side surfaces of the polygonal receptacle of the window or door handle. As a further alternative, the latching mechanism can have latching cams on a lower plate of the polygonal receptacle for the polygonal pin of the window or door handle, which interact with axially deflectable spring elements in the housing.

In a further embodiment of the invention, the rotary device for window and door handles has a locking device, comprising a lock arranged on the window or door handle, a cam disc with an axial pitch arranged on the lock, an axially displaceable locking pin arranged on the window or door handle and at least one receiving opening on the front side of the housing for the locking pin in its closed position, the locking pin having a groove in which the outer cam edge of the cam disc engages, such that a rotation of a key inserted into the lock converts its rotary movement into an axial translational movement of the locking pin and the locking pin moves between a release position and at least one blocking position for the operation of the window or door handle.

In a preferred embodiment of the locking device, the at least one housing-side receiving opening for the locking pin is in at least one arranged on the housing, the window or door handle facing attachment provided. Furthermore, a slit-like receiving opening can be provided, which extends in the shape of a partial circle over approximately 180°, or two discrete receiving openings offset by 180° relative to one another.

1 shows a section of a hollow profile 10 of a window or door sash, on which a rotating device, described in more detail below, for an operating handle for a gear or the like. is to be mounted. the Wall 12 of hollow profile 10 has a circular cutout 14 with two further circular segment cutouts 16, 18 adjoining its outer circumference.

2 shows above a schematic view of the cut-out 14 and the two circular segment cuts 16, 18 in the wall 12. In the lower part of the 2 a part of a housing 20 of the rotary device is shown schematically. The edge labeled 22 has the diameter of the cutout 14 . In the assembled position of the housing, clamping lugs 24 protrude slightly radially over the edge 22 . When the housing 20 is inserted into the wall 12, these are guided through the further circular segment millings 16, 18. The housing 20 is then rotated clockwise by an angle of approximately 30° until the projections 26 offset axially with respect to the clamping lugs 24 are aligned with the circular segment millings 16, 18 and can be brought into engagement with them to prevent the housing 20 from rotating. The clamping lugs 24 are then in an orientation with respect to the wall 12 in which they can be moved by actuating clamping screws 28 (see 4 and following) are brought into clamping contact with the back of the wall 12 . The housing is then fully assembled.

3 shows the installed state of the housing 20 in the hollow profile 10.

the Figures 4 and 5 show two variants of securing the clamping lugs 24 with their clamping screws 28 before the assembly of the housing 20 is carried out in the hollow profile 10. In 4 (such as Figures 9a and b , 10e , 11a and 12a and f), the securing is effected by a spring element 30, which is pushed onto the housing 20 transversely to the axial direction of the polygonal receptacle 32 and removed immediately before assembly. In figure 5 is secured by a positioning part 34, which is attached in the axial direction of the polygonal receptacle 32 and is also removed immediately before the assembly of the housing 20 in the wall 12.

the Figures 6 to 8 show three different variants of a latching determination of the position of the polygonal receptacle 32. In 6 Two spring plates 36 snap into recesses in the polygonal receptacle 32 and are held in position on the outer diameter of the housing 20 by the cutout 14. In 7 a shaped spring plate 38 is provided, which snaps into two depressions in the polygonal receptacle 32 and which is fixed inside the housing 20 . In 8 the polygonal receptacle 32 has latching cams 42 on a lower plate 40 which engage in recesses 44 in plastic parts 46 . The plastic parts are arranged to be axially displaceable against springs 48 supported on the housing 20 .

the Figures 9 to 13 show the previously described configurations of the rotary device in further views.

14 shows a variant of the rotating device with an additional locking device. A locking device, which has a cylinder lock with a rotor 52 and a stator 54 , is arranged in the window or door handle 50 . The rotor 52 has an insertion opening for a key 56 and at its end on the housing side a square 58 on which a cam disk 60 is placed (shown enlarged in detail A). Furthermore, in the window or door handle 50 there is a locking pin 64 which is pretensioned by a spring 62 and is arranged in an axially displaceable manner. The housing 20' is provided with structure cooperating with the locking pin 64 as discussed below. The cam disk 60 has on its periphery a rib 66 with an axial pitch which cooperates with a groove 68 in the locking pin 64 .

Figures 15a and b show a cross section through the mounted turning device with locking device. The lock is shown in a simplified manner in that the locking pins, which in the closed state cause rotation between the rotor 52 and the stator 54, are not shown. However, the structure and the function of such cylinder locks are sufficiently known to the person skilled in the art. As especially Figure 15b As can be seen, the rib 66 on the cam plate 60 engages a groove 68 in the locking pin 64 . When the key 56 is rotated in the lock, the rotational movement of the cam 60 is converted into an axial translational movement of the locking pin 64 due to the axial pitch of the rib 66 . Depending on the direction of rotation of the key 56, the locking pin 64 is thus pushed in the direction of the housing 20' or away from it.

16 shows the housing 20' with the structures of the locking device explained in more detail below, as well as various views of the cam disk 60.

17 shows an exploded view of the rotary device with two possible structures on the housing 20', which limit the rotation of the window or door handle 50 in the locked state. The housing 20' is secured on the polygonal receptacle 32 by two locking pieces 72, 72' engaging in a groove 70 in the polygonal receptacle 32. The locking pieces 72, 72' have a screw opening 74 and a threaded bore 76. The locking pieces 72, 72' are fastened to the housing by means of a socket head screw 78, 78'. In this state of the rotary device, locking of the window or door handle 50 is possible in a so-called tilt-before-turn constellation: while predominantly a rotation of the window or door handle 50, starting from a closed position of the relevant window or the relevant door, 90° to the rotary position of the window or door, so they can be fully opened, and only a rotation of the window or door handle 50 by 180° leads to the tilted position of the window or door, this order is in the tilt before -Rotate constellation reversed. This is desired where a user is not supposed to open the window fully (turned position), for example in hotels or the like. When locked, the window or door handle can only be turned through 90°. The rotation is limited by a cap 80 on the housing 20'. This has slot-like openings 82, 82' on the face side. For reasons of symmetry - the rotating device can be used both in windows or doors opening to the right as well as to the left are installed - two openings 82, 82' are provided, although only one of the openings 82, 82' is then used in the installed state. From the closed position of the window or door, in which the window or door handle 50 is aligned vertically and the locking pin 64 is in the 0° position (corresponding to a 12 o'clock position), the window or door handle can only be turned in the locked state 90° clockwise or counterclockwise, since the locking pin 64 then strikes the front end of the respective opening 82, 82'. However, authorized persons can unlock the lock and bring it into the rotary position, for example to clean the outside of the window or the door, since the locking pin 64 can be rotated freely in front of the top piece 80 when the locking pin 64 is retracted.

A further locking variant for the rotary device is achieved by two additional attachment pieces 84, 84', which are fastened to the housing 20' by means of screws 86, 86' which can be screwed into the threaded bores 76 of the locking pieces 72, 72': The window or the door should be lockable here both in the closed state (locking pin 64 at 0°) and in the tilted state (locking pin 64 at 180°), for example as burglary protection for terrace doors or the like. For this purpose, the attachment pieces 84, 84' each have a bore 88 which, in the assembled state, is arranged at 0° and 180° and can accommodate the locking pin 64 in the closed state.

the Figures 18a and b as well as 19a and b show the two aforementioned locking variants in the assembled state. In 18 a and b, the tilt-before-turn constellation is shown and in Figures 19a and b the 0°/180° locking variant.
