Description

[0001] The present invention relates to an actuating device for a door or window, comprising a square spindle. The square spindle has a first end region, on which a first handle is arranged, and a second end region. A second handle is arranged on the second end region of the square spindle.

[0002] It is known from the prior art to provide a square pin for operating a door lock or a window locking system. This square pin engages with a door lock or window lock or penetrates it in the area of a lock follower. In the known operating devices, the handles are usually screwed to the square pin.

[0003] Screwing the handles onto the square pin is labor- and time-intensive.

[0004] The invention is based on the object of providing an actuating device for a door or a window which, compared to the known actuating devices, requires less assembly effort.

[0005] This object is achieved according to the invention by the actuating device having the features of claim 1.

[0006] According to the invention, an actuating device for a door or a window is provided, which comprises a square pin, on which a first handle and a second handle are arranged, a clamping element and a spring element. The first handle is pushed onto a first end region of the square pin. In the first end region, a recess is formed in the square pin on a side surface, which recess deepens in the direction of the second handle, i.e. whose depth increases continuously in the longitudinal direction of the square pin. The clamping element is mounted in the recess so that it can be moved, in particular rolled, in the longitudinal direction of the square pin between a first position and a second position. In the first position, the first handle is movable relative to the square pin, in particular in the longitudinal direction of the square pin, i.e. can be pushed onto the square pin.When the clamping element is in the second position, the clamping element uses the first handle to forcefully secure the square pin. The spring element applies a force, particularly a compressive force, to the clamping element, particularly continuously, in the direction of the second position.

[0007] The core idea of the invention is therefore to provide a clamping element that is displaceable, in particular rollable, between a first position in which the first handle is movable relative to the square pin, in particular in the longitudinal direction of the square pin, and a second position in which the clamping element rests against the square pin and the first handle, in particular on opposite sides, in such a way that the first handle is secured to the square pin by means of a frictional connection. The first handle can thus be easily mounted on the square pin.

[0008] In the first position, for example, the locking element does not rest on the first handle or rests on it only with a small force and / or rests on the square pin with only a small force.

[0009] In the second position, the clamping element rests, for example, on the square pin and on the first handle in such a way that it applies a force to the square pin and the first handle, which, particularly in the vertical direction of the square pin, is greater than in the first position. The first handle is thus clamped to the square pin.

[0010] In a preferred embodiment of the actuating device according to the invention, the square pin has in the first end region a blind hole extending from an end face of the square pin in the longitudinal direction of the square pin, in which a slider is arranged.

[0011] The blind hole has, for example, in the axial direction, which corresponds to the longitudinal direction of the square pin, an extension such that the slider can be moved in the blind hole in the longitudinal direction of the square pin.

[0012] The slider may comprise a spring element bearing portion and a clamping element bearing portion, each of which is cylindrical in shape.

[0013] The spring element bearing section has, for example, a smaller diameter than the clamping element bearing section, so that an annular contact area is formed, against which the spring element rests at its first end, wherein the spring element rests at its second end opposite the first end against the square pin, in particular the bottom of the blind hole.

[0014] The slider may comprise, in particular in the clamping element bearing section, a notch for supporting the clamping element.

[0015] For example, when the actuating device is in a functionally correct assembly state, the notch extends continuously through the slide in the transverse direction of the square pin, and is therefore open at the side.

[0016] The notch may be arranged within the recess and / or be open in the same directions as the recess.

[0017] The spring element is arranged, for example, in the blind hole.

[0018] In an exemplary embodiment of the actuating device according to the invention, the clamping element is rotatably mounted in the notch. The clamping element is thus movable in the recess by a rolling movement relative to the square pin.

[0019] In a preferred embodiment of the actuating device according to the invention, a relative movement of the clamping element relative to the slider in the longitudinal direction of the square pin is prevented. Thus, a movement of the slider causes a movement of the clamping element, and vice versa.

[0020] In an exemplary embodiment of the actuating device according to the invention, the slider transfers the force of the spring element to the clamping element. The force of the spring element is therefore not transferred directly to the clamping element, but acts on the clamping element via the slider.

[0021] In a preferred embodiment of the actuating device according to the invention, the spring element is a helical spring.

[0022] In an exemplary embodiment of the actuating device according to the invention, the clamping element comprises two disc-shaped rolling bodies and a cylindrical connecting body connecting the rolling bodies to one another, wherein the center point of the rolling bodies lies in particular on the longitudinal axis of the connecting body.

[0023] The actuating element has, for example, a dumbbell shape.

[0024] When the actuating device is in a functionally correct installed state, the connecting body can extend in the transverse direction of the square pin.

[0025] For example, a longitudinal axis of the connecting body forms a rotation axis of the rolling elements.

[0026] In a preferred embodiment of the actuating device according to the invention, the connecting body is arranged in the notch of the slide, in particular the connecting body extends through the notch, and / or the rolling bodies are arranged laterally of the slide.

[0027] In an exemplary embodiment of the actuating device according to the invention, the rolling bodies rest on a rolling surface which delimits the recess on a first side, in particular at the bottom in the vertical direction of the square pin, thus forming a bottom of the recess.

[0028] In a preferred embodiment, the actuating device according to the invention comprises a securing element which secures the clamping element in the recess and / or the slider in the blind hole.

[0029] In an exemplary embodiment of the actuating device according to the invention, the securing element at least partially limits the notch on one side or at least partially closes it. This secures the clamping element in the notch.

[0030] In a preferred embodiment of the actuating device according to the invention, the locking element and / or a screw with which the locking element is fixed to the square pin closes the blind hole at least partially, in particular completely, at the end. This prevents the slide from being accidentally removed from the blind hole.

[0031] In an exemplary embodiment of the actuating device according to the invention, the blind hole has a blind hole thread into which a screw for fixing the securing element to the square pin is screwed.

[0032] The securing element may comprise an annular slide securing body.

[0033] The annular slide locking body, for example, rests against the square pin at the end, wherein the screw extends through a through hole of the slide locking body and a head of the screw rests against the slide locking body to secure the locking element.

[0034] The securing element may comprise a locking element securing body.

[0035] The square pin may comprise a recess in which the locking element securing body is arranged.

[0036] The geometry of the recess can correspond to the geometry of the locking element securing body, so that the top of the square pin and the top of the locking element securing body are arranged in the same plane. The locking element securing body thus does not protrude from the square pin, so that even when the securing element is mounted on the square pin, the handle can be easily slid onto the square pin.

[0037] The invention is explained in more detail below using an exemplary embodiment illustrated in the drawing. It shows: Figure 1 shows a perspective view of an actuating device according to the invention in a non-assembled state; Figure 2 shows a side view of the actuating device, without showing a first handle; Figure 3 shows a sectional view through the actuating device; Figure 4 shows a top view of a clamping element of the actuating device; Figure 5 shows a side view of a slider of the actuating device; Figure 6 shows a top view of a square pin of the actuating device; and Figure 7 shows a sectional view through the square pin along line VII-VII in Figure 6 .

[0038] In the Figures 1 and 3 An actuating device 2 according to the invention is shown. The actuating device 2 comprises a first handle 8, a second handle 10, and a square pin 4.

[0039] The first handle 8 is pushed onto the square pin 4 from a first side until it encloses a first end region of the square pin 4. The second handle 10 is pushed onto the opposite second side of the square pin 4 so that it encloses a second end region of the square pin 4.

[0040] The second handle 10 is screwed to the square pin 4 by means of a screw 44. It is also conceivable to fix the second handle 10 to the square pin 4 in another way.

[0041] At a first end of the square pin 4 in the longitudinal direction of the square pin, which lies in the first end region, a blind hole 18 is formed, which extends toward the opposite second end. The blind hole 18 is thus formed on one end face of the square pin 4 and extends in its longitudinal direction.

[0042] The square pin 4 has a recess 16 on a side surface in the first end region, which is bounded by a rolling surface at the bottom in the vertical direction z of the square pin and by side walls in the longitudinal direction x of the square pin. The recess 16 is open upwards in the vertical direction z of the square pin and laterally in the transverse direction y of the square pin.

[0043] As can be seen in particular from the Figure 7 As can be seen in the sectional view through the square pin 4 shown, the rolling surface is inclined downwards in the direction of the second end region of the square pin 4. The recess 16 thus deepens in the square pin's longitudinal direction x toward a center of the square pin 4.

[0044] The blind hole 18 has a depth such that, in particular, the entire rolling surface, which delimits the recess 16 at the bottom in the vertical direction z of the square pin, is arranged below a longitudinal center axis of the blind hole 18. The blind hole 18 and the recess 16 overlap in a partial area, so that an intersection area is formed in which the blind hole 18 is exposed upwards via the recess 16, i.e., in the vertical direction z of the square pin.

[0045] A spring element 14 and a slide 22 are arranged in the blind hole 18. As can be seen from the illustration of the slide 22 in Figure 5As can be seen, the slider 22 comprises a spring element bearing section 24 and a clamping element bearing section 26. The spring element bearing section 24 and the clamping element bearing section 26 each have a cylindrical shape. The diameter of the spring element bearing section 24 is smaller than the diameter of the clamping element bearing section 26, so that an annular contact area 46 is formed.

[0046] The spring element 14 is a spiral spring which is arranged at least partially on the spring element bearing section 24 in an end region facing the slide 22 in the square pin longitudinal direction x, rests at a first end on the annular contact region 46 and rests at the opposite second end on a bottom of the blind hole 18.

[0047] The clamping element bearing section 26 has a notch 28. The notch 28 extends downward in the vertical direction z of the square pin, i.e., it is open upward in the vertical direction z of the square pin. In the transverse direction y of the square pin, the notch 28 extends through the entire clamping element bearing section 26, i.e., it is open laterally. Viewed from the side or in a section along the axial direction of the slide 22, the notch 28 has a U-shaped profile. The notch 28 is thus designed in the form of a U-shaped groove extending transversely to the axial direction of the slide 22.

[0048] The notch 28 has a smaller extension than the recess 16 in the axial direction of the slider 22, which in a functionally correct installed state of the fastening device 2 corresponds to the square pin longitudinal direction x. In a functionally correct installed state of the fastening device 2, the slider 22 is displaceable in the blind hole 18 in the square pin longitudinal direction x such that the notch 28, in particular in each displacement position, is arranged within the recess 16.

[0049] In the notch 28, a clamping element 12 is rotatably mounted about a rotational axis extending in the transverse direction y of the square pin. The clamping element 12 comprises two disc-shaped rolling elements 30, which are connected to one another via a cylindrical connecting element 32 (see Figure 4 ).

[0050] In a functionally installed state of the fastening device 2, the connecting body 32 is arranged in the notch 28. In particular, the connecting body 32 extends through the notch 28 in the square pin transverse direction y. The geometric design of the connecting body 32 corresponds to the geometry of the notch 28 such that the clamping element 12 is mounted in the notch 28 so as to be rotatable about a rotation axis extending in the square pin transverse direction y, but is not, or only slightly, translationally movable relative to the slider 22 in the square pin longitudinal direction x. A translational movement of the slider 22 in the square pin longitudinal direction x thus causes a corresponding translational movement of the clamping element 12 and vice versa, in particular at least from a movement that exceeds the play required for the rotatable mounting of the clamping element 12 in the notch 28.However, due to the upwardly open design of the notch 28 in the vertical direction z of the square pin, a translational movement of the clamping element 12 in the vertical direction z of the square pin relative to the slider 22 is possible. The range of motion is limited by the support of the connecting body 32 on a base defining the bottom of the notch 28.

[0051] The rolling elements 30 are located laterally of the notch 28 in the transverse direction y of the square pin and rest on the rolling surface that borders the bottom of the recess 16. The clamping element 12 can thus be moved between a first position and a second position by a rolling movement on the rolling surface relative to the square pin 4 in the longitudinal direction x of the square pin. Due to the inclined design of the rolling surface, a movement of the clamping element 12 in the recess 16 in the longitudinal direction x of the square pin simultaneously causes a change in the position of the clamping element 12 in the vertical direction z of the square pin.

[0052] In the first position, the clamping element 12 is located closer to the second end region of the square pin 4 in the square pin longitudinal direction x and is arranged further down in the square pin vertical direction z than in the second position. The change in position in the square pin vertical direction z is such that the clamping element 12 in the first position is spaced from the first handle 8, in particular an insert element 6 of the first handle 8, or at least only slightly rests against it. In the second position, however, the clamping element 12 rests against the insert element 6 and on the rolling surface in such a way that it non-positively connects or clamps the first handle 8 and the square pin 4.

[0053] The actuating device 2 further comprises a securing element 34, which secures the clamping element 12 in the recess 16 and the slide 22 and the spring element 14 in the blind hole 18. For this purpose, the securing element 34 has a slide securing body 38 and a locking element securing body 40.

[0054] The slider securing body 38 is annular and extends in the vertical direction z of the square pin and the transverse direction y of the square pin. The slider securing body 38 rests against the first end of the square pin 4 and is fixed to the square pin 4 by means of a screw 36. The slider 22 and the spring element 14 are secured in the blind hole 18 by means of the securing element 34 in such a way that the spring element 14 exerts a compressive force on the slider 22 in every position of the slider 22 in the blind hole 18, which compressive force acts in the longitudinal direction x of the square pin in the direction of the first end of the square pin 4, thus moving the slider 22 in one direction from the first position to the second position.

[0055] The locking element securing body 40 is designed in the form of a narrow, rectangular element that extends in the square pin longitudinal direction x and the square pin transverse direction y. In the square pin longitudinal direction x, the locking element securing body 40 has an extension such that it extends over the entire recess 16 or at least partially delimits the recess 16 at the top over its entire extension in the square pin longitudinal direction x in the square pin vertical direction z. In the square pin transverse direction y, the locking element securing body 40 is designed to be so narrow that movement of the clamping element 12 is unimpaired by the locking element securing body 40. The locking element securing body 40 therefore has an extension in the square pin transverse direction y that is at least slightly smaller than an extension of the cylindrical connecting body 32 in the same direction.

[0056] The square pin 4 comprises on its upper side a recess 42 corresponding to the geometry of the locking element securing body 40. The locking element securing body 40 therefore does not protrude from the square pin 4 in the vertical direction z of the square pin. In particular, the upper side of the square pin 4 and the upper side of the locking element securing body 40 are arranged in the same plane.

[0057] When assembling the actuating device 2, the square pin 4 is fixed to the second handle 10 by means of the screw 44. The spring element 14 and the slide 22 are arranged in the blind hole 18. The clamping element 12 is mounted in the recess 16 in the notch 28 of the slide 22. The locking element 34 is fixed to the square pin 4 by means of the screw 36.

[0058] The square pin 4 is then pushed through a lock nut of a door or window until the second handle 10 rests against a first side of the door or window and the first end region protrudes on the opposite side of the door or window.

[0059] The first handle 8 is slid onto the square pin 4. A force acts on the clamping element 12 such that the clamping element 12 is moved from the second position to the first position, counter to the force acting on the slider 22 and thus on the locking element 12, i.e., is displaced in the square pin longitudinal direction x toward the second end. By displacing the clamping element 12 in the square pin longitudinal direction x toward the second end region and due to the inclined configuration of the rolling surface, the clamping element 12 is moved downward in the square pin vertical direction z. The downward movement of the clamping element 12 in the square pin vertical direction z enables the first handle 8 to be pushed further onto the square pin 4.

[0060] If the first handle 8 is no longer moved relative to the square pin 4, the first handle 8 no longer exerts a force in the square pin longitudinal direction x on the clamping element 12, which counteracts the force acting on the clamping element 12 through the spring element 14. The force acting on the clamping element 12 through the spring element 14 moves the clamping element 12 from the first position back to the second position. In the second position, the clamping element 12 rests against the insert element 6 and on the square pin 4 in such a way that the first handle 8 is secured to the square pin 4 by means of a frictional connection.
