Description

The invention relates to a rotary handle for a closure of a wing of a window, a door or the like, in particular a sliding leaf, with an operating handle which is at least partially recessed in its rest position in terms of height in the wing and from the rest position to a working position as a folding handle can be swung out in outstanding position, wherein it is rotatable in the working position about a rotation axis, and with an operating element with which a coupling or uncoupling takes place with a co-rotating with the operating handle in the coupling position and not unwinding in uncoupled control, the operating handle, the operating element having

A rotary handle of the type mentioned is from the DE 102 04 744 A1 known. It has an actuating handle, which sunk in its rest position rests in the associated wing and can be folded out of this rest position into a working position, so that at least a portion of the operating handle protrudes from the plane of the wing. Subsequently, the operating handle can be rotated by operating the shutter. By sinking the operating handle, an adjacent wing can be moved in parallel at a short distance on the first-mentioned wing, without causing a collision with the rotary handle. The prerequisite is that the rotary handle is first returned under actuation of the shutter in the output rotational position and then folded in lowered position.

Another rotary handle according to the preamble of claim 1 is known from EP 0 556 420 A1 known. The operating handle rests in its rest position sunk in the associated wing or in a sinking niche provided therein and can be brought from this rest position to a working position. In order to bring the operating handle from the working position to the rest position, an existing on the operating handle swivel control element must be actuated, whereby a locking device is released, and then the operating handle can be folded. A clutch lever cooperates with a control, wherein the control in the coupling position with the actuating handle co-rotatable and uncoupled in uncoupled position. Subsequently, the operating handle can be rotated, wherein the closure is actuated.

The invention has for its object to provide a rotary handle of the type mentioned, which is more versatile and even less annoying, with a very simple operation of the rotary handle is possible. This object is achieved according to the invention in that the operating element is a sliding element and the operating element interacts with a pivoting element which is disengaged from the control element in a coupling position and in a disengaging position with the control element. Due to the design with an operating element with which a coupling or uncoupling position to a co-rotating with the actuating handle in the coupling position and not unwinding in uncoupled control, the operating handle in any desired rotational position with the control can couple or decouple, so he always in his Quiescent, so submerged location can be traced independently of which caused by the rotational position operating position is present at the control. It can therefore be spent, for example, in the locked position in its rest position. Was the wing unlocked by bringing about the corresponding rotational position of the actuating handle, so there is an unlocking position as the operating position, so can the operating handle by uncoupling of the remaining in the unlocking control control still in its rest position, ie spend in sinking position, so that in this operating position of Actuating handle does not interfere with the sides of the wing. The same applies to other operating positions that can possibly be approached by turning the operating handle. Due to the invention thus the position of the control is independent of the current position of the operating handle. In this case, the operating handle to the operating element. Since the operating element is located on the actuating handle, a particularly simple, preferably one-hand operation is possible since, when the operating handle is gripped, an actuation of the operating element-if desired-can additionally take place. According to the invention, the operating element is designed as a sliding element. This is a very simple operation of the control by sliding movement possible. Preferably, the operating handle is enclosed with the user's hand, where he can press the sliding element with his thumb. It is provided according to the invention that the operating element cooperates with a pivoting element, which is in a coupling position with the control element in engagement and in a disengaged position with the control element out of engagement. By means of the control element can thus influence the pivoting element in its position, such that a coupling between the actuating handle and the control is made so that upon rotation of the actuating handle, a corresponding rotational movement of the control takes place or that by disengagement, ie an actuation of the control element such that the pivot member is disengaged from the control, whereby a rotational movement of the actuating handle is possible without the control is taken , It therefore remains in its respective position. The operating handle, however, can be returned, for example, from the working position to the rest position and thereby has a sunken, non-interfering position.

It is advantageous if the actuating handle and / or the operating element is a manually operable component or are manually operable components. In such a case or in these cases, the rotary handle is thus actuated manually by the user. Should a motor actuation take place, the rotary handle can also be driven by a motor in relation to its actuating handle and / or the operating element.

A development of the invention provides that the pivoting element is mounted pivotably about a pivot axis. The actuating handle is preferably also hinged around this pivot axis as a folding handle. Accordingly, the pivot axis forms a common axis for the pivot member and the operating handle.

It is advantageous if the operating element is coupled to a slider or has the slider, wherein the slider cooperates with the pivoting element. A shift of the slider causes the pivoting element is brought into its coupling position or uncoupling position.

As already mentioned, it is preferably provided that the pivoting element rotates when the operating handle is rotated about its axis of rotation. If the pivoting element is not coupled to the control element, the operating handle and the pivoting element are rotated without the control element rotating. If there is a coupling between the pivoting element and the control element, the control element is entrained when the operating handle is rotated via the pivoting element.

It is preferred if the coupling or uncoupling position can be brought about independently of the rotational position of the actuating handle with the operating element. This leads - as already mentioned - to the independence of the positions of the operating handle and control, if the uncoupling is present. If the coupling position is selected, a rotation of the actuating handle leads to the entrainment of the control.

The control element preferably has a control bolt, in particular a polygonal bolt, preferably a square bolt. It serves for the rotationally fixed entrainment of a closure actuating element, for example a gear, the teeth of which mesh with recesses of drive rods.

According to a development of the invention, it is provided that the control cooperates with a rotational locking position device. Due to the rotational locking positions, the control can be noticeably turned into certain positions, for example into a locking position and an unlocking position. These two Positions are felt by the user due to the rotation lock position device, but can be overcome by a corresponding, slightly increased effort.

A development of the invention is characterized by a housing, in which the operating handle in the rest position is at least partially retractable with respect to its height. The housing is designed in particular as a built-in housing.

As already mentioned, the actuating handle is in the rest position completely or substantially sunk in the housing, in particular installation housing. If the actuating handle is in the working position, its longitudinal extent forms an acute angle with the longitudinal extension of the housing.

Furthermore, it is advantageous if the control is mounted floating in the housing. In particular, it is provided that the control spring-loaded axially by a spring in the housing. It can preferably be provided that the spring acts between the control element and a rotatable part rotatably mounted in the housing. In particular, it is provided that the spring acts on a ball bearing, which is supported on the rotary member or on the control. In particular, it may be provided that the bearing ball rests with a partial spherical surface in a bearing recess of the rotary member or the control. In particular, due to this aforementioned storage of the control in the housing is achieved that tolerances, misalignments and the like can be compensated for the closure to be coupled. In particular, it is provided that the operating handle is pivotally mounted on the rotary member.

Finally, the invention relates to a method for actuating a closure of a wing of a window, a door or the like, in particular a sliding leaf, by means of a rotary handle, which is formed as mentioned above.

The FIG. 1 shows the front view of a rotary handle 1, with a non-illustrated closure of a wing of a window, a door or the like, in particular a sliding leaf, can be actuated. The rotary handle 1 has a handle 2 designed as a folding handle 3. The rotary handle 1 has a housing 4, which is designed as a mounting housing 5. A front panel 6 has a gripping edge 7 such that a recessed installation of the rotary handle 1 in a corresponding recess of the sliding leaf is possible, with only the grip edge 7 is supported on the top of the sliding leaf.

The folding handle 2 is located in the FIG. 1 in its rest position, in which its top 8 is aligned with the top 9 of the front panel 6. Again FIG. 1 can be seen, the rotary handle 1 is elongated and it is therefore also an elongated shape before the operating handle 3. However, this does not extend with its lower end portion 10 to the lower associated end 11 of the housing 4, so that an engagement recess 12 is formed. The user can therefore engage with a finger in the engaging recess 12 and the underside and / or the lower edge region of the actuating handle 3 apply to him in the folded position according to FIG. 6 to relocate. This folding position represents a working position. The operating handle 3 is an operating element 13, which can be preferably operated by the user with the thumb. The operating element is designed as a sliding element 14 and is located in the FIG. 1 in an ineffective engagement. This Ineingriffwirkung will not be effective because the operating handle 3 is in rest position.

The FIG. 2 shows a side view of the installation housing 5, wherein the operating handle 3 is in rest position. From the back 15 of the mounting housing protrudes a control 16 out, which is rotatably mounted about a rotation axis 17. The control element 16 preferably has a control bolt 18, in particular a polygonal bolt 19, preferably a square bolt 20. When inserting the rotary handle 1 in the recess of the sliding leaf, the control 16 rotatably coupled to a corresponding actuator of a closure of the sliding leaf, so that a rotation of the control leads to an actuation of the closure.

The FIG. 3 shows a rear view of the rotary handle 1. The housing 4 is closed by a rear wall 21 in its upper region. The rear wall 21 is held by four threaded screws 22. The formation of the control element 16 as a square bolt 20 is the FIG. 3 to be taken clearly.

The FIG. 4 shows an end view of the rotary handle. 1

The FIG. 5 shows - in longitudinal section view - the internal structure of the rotary handle 1. The operating handle 3 is about a pivot axis 23 which is formed by a bearing pin 24, pivotable, the two pivot end positions (rest position and working position) from a comparison of Figures 5 and 6 evident. The bearing pin 24 is arranged on a torsion part 25, which is preferably rotatable about the rotation axis 17 by 360 °. About the pivot axis 23, a pivot member 26 is pivotally mounted. For this purpose, the bearing pin 24 passes through a receiving bore 27 of the pivoting element. Spaced to the pivot axis 23, the pivot member 26 has a control surface 28 which is formed as an inclined surface 29. For this purpose, facing away from the pivot axis 23, there is a driving end 30 of the pivoting element 26. The operating element 13 designed as a sliding element 14 is coupled to a slide 31, wherein the slide 31 is mounted longitudinally displaceable on the actuating handle 3 and preferably has a control surface 33 at one end 32, which is designed as an inclined surface 34. The slider 31 is biased by means of a spring 35, which is designed as a helical compression spring 36, in the direction of the operating element 13 (arrow 37). For this purpose, the helical compression spring 36 is supported both on the actuating handle 3, and on the slide 31. The trained as a sliding element 14 operating element 13 is in Direction of the double arrow 38 - as well as the slider 31 - slidably mounted on the operating handle 3.

The control element 16 has the already mentioned square bolt 20, to which a cross-sectional larger circular cross-section 39 connects, which is rotatably mounted about the axis of rotation 17 in a bearing cup 40. The bearing cup 40 is located within the housing 4 in a rotationally fixed position. It has two diametrically opposite spring shafts 41. Further, the bearing cup 40 passes through the back 15 of the housing 4 with a tube extension 42. In the two spring shafts 41, which are closed to the rear of the back 15 of the housing 4, springs 43 are formed, which are formed as helical compression springs 44. The two helical compression springs 44 each act on a detent ball 45, wherein the two detent balls 45 - according to FIG. 8 - In recesses 46 on the circumference of a flange 47 of the control 16 - depending on the rotational position of the control element 16, can occur and thereby define preferred positions of the control 16. The flange 47 is designed substantially disc-shaped and connects to the circular cross-section 39 at. The flange 47 has on its rear side 48 a recess 49. From the rear 48 is a blind bore 50 extends, which is coaxial with the axis of rotation 17 and a spring 51 receives, which is designed as a helical compression spring 52 and a bearing ball 53 is applied, which thereby against the Twisted part 25 is urged and rests with a partial spherical surface in a shape-adapted bearing recess 54 of the Verdrehteils 25. Due to the action of the spring force of the helical compression spring 52, the control element 16 in the direction of the arrow 55 (FIG. FIG. 5 ). It is - depending on the operating condition - with its flange 47 on the bearing pot 40 and urges this also in the direction of the arrow 55, so that it is urged against the inside of the back 15 of the housing 4. It can be seen from all this that the control element 16 is mounted to a certain extent floating in the housing 4, so that any existing tolerances, positional errors and misalignment with respect to the coupling with the square bolt 20 can be compensated for the mentioned closure.

The designed as a mounting housing 5 housing 4 can be fixed in the lowered position due to three mounting holes 56 by means of suitable mounting screws on said sliding leaf. "Countersink" means that the top of the front panel 6 is flush with or substantially flush with the corresponding surface of the sash.

According to the FIGS. 8 and 9 located inside the housing 4, an inner bearing part 57 which consists of a first bearing part 58 and a second bearing part 59 and is screwed by means of four threaded screws 60 with the housing 4.

The structure of the rotary handle 1 is in particular from the exploded view of FIG. 9 out. Among other things, it can be seen that the rotary member 25 has bearing blocks 61, which are penetrated by the bearing pin 24. A friction ring 62 receives the edge of the torsion 25 and supports the torsion 25 in a receptacle 63 of the inner bearing part 15. One of the mounting holes 56 is formed in an insert 64, which is insertable into the housing 4. The slider 31 is held on the operating handle 3 by means of a back cover 65. The rocker-like pivot member 26 is associated with a spring 66 which, according to arrow 67 in FIG. 5 the Pivoting member 26 is rotated in the clockwise direction about the pivot axis 23, whereby the control surfaces 28 and 33 collide. A spring 68, which is formed as a helical compression spring 69, acts on the rear side of the actuating handle 23 by corresponding support on an inner surface of the housing 4 such that the actuating handle 3 about the pivot axis 23 in the direction of its rest position FIG. 5 is urged. By means of a clip-on screw head cover 70, the associated mounting hole 56 can be covered.

The result is the following function: If the rotary handle 1 is in accordance with FIG. 5 in rest position, that is, the operating handle 3 is collapsed, so the rotary handle is aligned in this state with the sliding sash of a window, a door or the like, in which it is installed sunk. Since no part of the rotary handle protrudes, the sliding leaves mehrflügliger arrangements can be placed very closely adjacent to each other and push past each other, without causing collisions of the rotary handle with a sliding past wings. If the associated closure is actuated by means of the rotary handle, the user grips with one finger into the engagement recess 12 and pivots the actuating handle 3 into its working position, which is out of the FIG. 6 evident. Of the FIG. 6 It can also be seen that the driving end 30 of the pivoting element 26 enters the recess 49 of the control element 16 by the pivoting of the actuating handle 3 about the pivot axis 23. As a result, a rotary coupling is provided between the actuating handle 3, which is rotatably mounted about the axis of rotation 17, and the control element 16. From the FIG. 6 It can be seen that in this situation, the control element 13 assumes a position supported by the spring 35, wherein by the Displacement of the actuating handle 3 from the rest position into the working position of the slider 31, the pivot member 26 is acted upon such that it couples with the control element 16.

The situation according to FIG. 5 goes again in perspective plan view and partial sectional view of the FIG. 10 out. The situation according to FIG. 6 also goes in perspective view and partial sectional view of the FIG. 11 out. The FIG. 7 illustrates the internal structure of the rotary handle 1 based on a partially cutaway perspective view of the rotary handle 1. Here, the actuating handle 3 is in its rest position.

The FIG. 12 shows a rotational position of the operating handle 3 of the rotary handle 1, which from the situation according to FIG. 11 can be brought about. For this the user rotates - starting from the situation of the FIG. 11 - The actuating pin 3 about the axis of rotation 17. Here, the pivot member 26 takes the control 16, so that by means of the square bolt 20, a closure of the wing can be operated. For example, this allows the closure spend from its locking position in its unlocked position. It is now possible, for example, to shift the sliding sash out of its closed position into an opening sliding position. In order to eliminate a disturbing protrusion of the actuating handle 3 out of its housing 4, it is - according to FIG. 13 - Now possible, by operating the control element 13 to shift the slider 31 so that its control surface 33 leaves the control surface 28 of the pivot member 26 and an adjacent actuating surface 71 of the pivot member 16 so acted that it against the action of the spring 66 to the bearing pin 24th pivoted, whereby the driving end 30 of the recess 49 of the control 16 exits and therefore there is no more coupling between the operating handle 3 and the control element 16. It is therefore possible, without the position of the control element 16 is changed, now the operating handle 3 in the position according to FIG. 11 attributed and in the position according to FIG. 10 to fold. The result is that now the wing is not surmounted laterally by disturbing elements and therefore, for example, an adjacent wing can be pushed very close to the wing.

According to FIG. 14 It is also possible to make not only a 90 ° rotation of the operating handle 3 and the control element 16, but for example a 180 ° rotation. Also in the position of FIG. 14 a decoupling of the actuating handle 3 can be made by the control 16 by means of the operation of the control element 13. The operating element 13 is preferably actuated by means of the thumb of the user. Also from the position of FIG. 15 can the operating handle 3 in its position according to FIG. 10 return, without causing the control 16 is displaced from the 180 ° twist position. Of course, other angles of rotation can be realized. The various angles of rotation are preferably characterized by slight latching effects of the latching balls 15, which can enter into correspondingly arranged latching recesses 46 of the flange 47 of the control element 16.

If the sliding sash to be locked again by appropriate actuation of its closure, the operating handle 3 from the position of FIG. 10 with actuated control element 13 first in the position of FIG. 11 spent, then - at a 90 ° twist - in the position according to FIG. 13 twisted, then through Actuation of the control element 13 brought about the coupling position with the control element 13 and then with entrainment of the control element 16 in the position according to FIG. 11 spent and then in the rest position according to FIG. 10 pivoted.
