Description

[0001] The present invention relates to an operating handle for components such as windows and doors, according to the preamble of claim 1.

[0002] Many variations of operating handles for operating doors and windows are known in the art. They typically have a actuator that moves the operating device within the window or door sash, for example, via a window gearbox on a vehicle. For example, the actuator may have a square design.

[0003] In order to open and close a window or door, in addition to rotational movement, a pulling or pushing force must be transmitted from the handle to the window or door sash. Therefore, the connection between the handle and the actuator is designed so that they are axially connected in a non-rotatable manner after assembly.

[0004] It is well known that it is possible to implement operating handles on window and door sashes without rosettes. However, this results in very limited installation space.

[0005] For example, an operating handle is known in EP 1683933 B1, wherein the driving element can be secured in the handle by a blocking or clamping element by pushing the driving element into the handle.

[0006] One object of the present invention is to manufacture an operating handle that has a particularly convenient and rapid action for securing an actuator to an operating device in a window or door sash, wherein the operating handle can perform this action simultaneously without a rosette. Preferably, a locking function is also implemented simultaneously.

[0007] The main features of the invention are listed in the characterizing portion of claim 1. Claims 2 to 12 are embodiments.

[0008] This invention provides an operating handle for components such as windows and doors, the handle having at least one drive element that engages with the handle for combined rotation, and a gearbox socket for integration into a window or door gearbox. The invention is characterized in that the gearbox socket has a groove extending through a rotation axis of the gearbox socket, and at least one spring-loaded blocking or clamping element pivotally mounted therein, wherein the blocking or clamping element can engage with the drive element through force, shape fitting, and / or frictional engagement, and the gearbox socket has a radially inwardly oriented locking recess on its outer circumference for receiving the locking element.

[0009] According to the operating handle of the present invention, various functions for achieving the above-mentioned objectives are directly integrated into the gearbox socket.

[0010] A gearbox socket is a component installed in the window gearbox, or similarly, to drive different elements there. In this case, the gearbox socket preferably has an external tooth profile, for example, that meshes with a rack or other corresponding toothed element. If the gearbox socket is rotated by a drive element, the window gearbox also moves accordingly. The gearbox socket can be fully integrated into the window gearbox and is therefore entirely located within the corresponding window or door sash.

[0011] The gearbox receptacle has a recess that preferably extends axially through the gearbox receptacle. A drive element is provided through the recess to establish a connection for joint rotation of the gearbox receptacle. For this purpose, at least one blocking or clamping element is provided within the recess and is designed to establish a connection with the drive element by pushing the drive element in. This is preferably implemented as described in EP 1 683 933 B1, because the drive element is inserted into the recess where it engages with the blocking or clamping element so that they are connected to each other. Due to the spring-loaded mounting, the blocking or clamping element allows for a change of direction when the drive element is inserted so that the two elements can follow the movement of the drive element to engage with each other. At the same time, the wedging of the locking or clamping element with the drive element prevents pull-out. Because the blocking or clamping element is provided within the gearbox receptacle, there is no need to provide a knot or other elements that increase installation space, which protrude outward through the door or window sash. However, a secure connection can be established between the drive element and the window gearbox.

[0012] The locking function can also be achieved by using a gearbox socket with a locking recess on its circumference. For example, a spring-loaded locking device can be installed in the window gearbox, which is radially guided by spring force to the gearbox socket and pressed against its circumference. The locking recess allows selective engagement between the locking device and the locking recess, which results in the locking force being released again by applying sufficient torque to the actuating element. The release force or release torque can be set by the size of the locking device, the locking recess, and the spring force.

[0013] The integration of this device for connecting the drive element to the window gearbox and the locking function in the gearbox socket results in a particularly simple, compact, and complete integration within the window or door sash. Separate connecting or locking devices outside the window or door sash are unnecessary, and the operating handle according to the invention can be designed entirely without rosettes. No modifications are required to any openings or cutouts in the window or door sash, provided that the gearbox socket does not exceed customary, specified, and / or standardized dimensions.

[0014] In a preferred embodiment, the gearbox socket is divided into two axial halves, with grooves extending into both halves. The grooves can be manufactured by machining the two halves and then assembling them. This division into two halves means that more complex groove shapes can also be produced. For example, shoulders or edges can be formed in the grooves, by which blocking or clamping elements can enter the base. Once the blocking or clamping elements are inserted into the gearbox socket, the two halves can be axially screwed or glued together.

[0015] In an advantageous embodiment, the groove has undercuts to secure a blocking or clamping element. The groove may have undercuts from two axial directions, thus the groove diameter increases abruptly inward in the axial direction, at least at one point. Two jumps in diameter can be provided, spaced apart from each other, with the undercuts facing each other and forming a cavity for receiving the blocking or clamping element. The two undercuts are then preferably symmetrically designed and arranged symmetrically to each other.

[0016] In a similarly advantageous embodiment, the blocking or clamping element has a clamping frame with an opening that matches the profile of the drive element for receiving and closing the drive element. The drive element can extend through the opening of the clamping frame. Due to a rotatable spring-loaded mounting, after the drive element is inserted, the clamping frame can be tilted toward the drive element—depending on the size of the drive element opening. Particularly when the opening has a sharp profile, the clamping frame may be wedged into the drive element when the direction of movement of the drive element is opposite. The clamping frame can be designed such that if a force in the opposite direction continues to be applied, the position of the clamping frame becomes more tilted in order to remove the drive element, thus making the two elements more wedged together.

[0017] The clamping frame facilitates rotation between a first position and a second position, wherein the surface normal of the plane spanned by the clamping frame extends obliquely towards the axis of rotation in the first position and runs parallel to the axis of rotation in the second position. The pivot can run perpendicular to the axis of rotation and thus extend laterally through the longitudinal axis of the actuator element. For example, the pivot can obliquely span the cross-sectional area of ​​the actuator element. Therefore, when the clamping frame is tilted, it may wedge against two adjacent surfaces of the actuator element. If the clamping frame is at least substantially in the second position, the actuator element can be guided through. Due to the spring-loaded mounting, the clamping frame is preferably always forced into the first position, but due to the actuator element being pushed through, the clamping frame is forced into the direction of the second position.

[0018] Furthermore, the groove can have a sloping inner end face boundary surface, and the clamping frame can fit snugly against this surface to occupy the initial position. Therefore, when the drive element is not inserted, the gearbox socket is in a state that allows the drive element to be pushed in, because the drive element is always gently pressed against the clamping frame under spring force, allowing the drive element to slide through the opening of the clamping frame. However, from the beginning of the process, the orientation of the clamping frame is as sloping as possible. The orientation in the neutral state can be ensured by a properly designed inner end face boundary surface.

[0019] In another advantageous embodiment, the profile of the clamping frame is designed to match the inner profile of the groove. Therefore, the clamping frame fills the inner profile of the groove. If the profile is not circular, it can transmit torque. The slight difference in dimensions between the clamping frame profile and the inner profile of the groove means that the clamping frame can rotate fully.

[0020] Furthermore, it is advantageous for at least one blocking or clamping element to have two clamping frames with a compression spring arranged between them. In each case, the drive element can then wedge into one of the two clamping frames, depending on its orientation when inserted into the gearbox socket. Therefore, it is suitable for immediate use both clockwise and counter-clockwise after installation. There is no need to check the orientation and rotate the gearbox socket before installation into the window gearbox.

[0021] If two clamping frames are used, the recess preferably has two inner end face boundary surfaces that are opposite each other and run in a mirror-inverted manner. In each case, one of the clamping frames can fit tightly against this surface to take its first position. Mounting from both directions allows the clamping frames and drive element to be reliably wedged in. Furthermore, the drive element can be inserted into the gearbox socket from both directions, so it is not necessary to rotate the gearbox socket. In this case, a pin can be inserted laterally into the gearbox socket from the outside through a transverse hole, laterally to the axis of rotation, to move one of the two clamping frames (which should laterally be inactive) to a second position, allowing the drive element to slide over and be permanently secured there. The surface normal of the plane spanned by the clamping frame is then parallel to the axis of rotation, where the clamping frame is held stationary. The opening of the clamping frame is aligned with the drive element and does not counteract the axial movement of the drive element. After the drive element is pushed over, the clamping frame only acts as a base for the compression spring located between the clamping frames.

[0022] Therefore, in an advantageous embodiment, the gearbox socket has two transverse holes into which pins can be inserted to vertically secure one of the clamping frames to the rotating shaft in each case.

[0023] In a particularly advantageous embodiment, the gearbox socket has a slit arranged along the groove for the passage of a tool, which is used to move a blocking or clamping element against a spring force. The tool can be an elongated element, inserted through the slit in the gearbox socket, and enters the base along with the blocking or clamping element there. It can then be moved accordingly under the spring force to release the wedging with the drive element, thereby releasing the drive element again. The slit may be much smaller than the groove. For example, its width may be only 3 mm or less to allow insertion of a suitable tool, such as a fine screwdriver or a fine wrench. The slit may be arranged at the edge of the groove. A space may be provided between the groove and the slit, but this is not necessary.

[0024] In another advantageous embodiment, the locking recesses are evenly spaced apart from each other in the circumferential direction. The space between the locking recesses depends on the desired locking position. It is conceivable that at least three locking positions spaced 45° apart from each other are integrated together to signal the handle position for a closed, fully open, or tilted window.

[0025] Furthermore, it is advantageous for the locking recess to have a circular segment profile. In particular, spherical or spherically segmented locking elements can engage with the locking recess and reliably release from it again. In addition to the spring force acting on the locking element, the segment height or the central angle of the locking recess profile can also determine the retaining force of the locking element in the locking recess.

[0026] Further features, details, and advantages of the invention arise from the wording of the claims and the description of exemplary embodiments with reference to the accompanying drawings. In the drawings:

[0027] Figure 1 A partial cross-section of the gearbox socket in the first embodiment is illustrated.

[0028] Figure 2a and 2b The illustration depicts a car window gearbox, which includes a gearbox socket.

[0029] Figures 3a to 3c The operating handle is shown in the sectional view (3a), the assembly (3b), and during the release of the handle from the window sash (3c).

[0030] Figure 4a and 4b The diagram illustrates the gearbox socket in the window gearbox during the release of the drive element.

[0031] Figure 5a and 5b Exploded and sectional views (5b) show alternative variants of the gearbox socket.

[0032] Figures 6a to 6dThe diagram illustrates the process of inserting the drive element into the gearbox socket from two directions.

[0033] Figure 7a The gearbox socket is illustrated during the release of the drive element.

[0034] Figure 7b and 7c One of the transverse holes for inserting a pin into a gearbox socket is shown.

[0035] Figure 1 A gearbox socket 2 for integration into a vehicle window gearbox or door gearbox is shown. The gearbox socket 2 has two axial halves 4 and 6, which, when placed together, form the body of the gearbox socket 2. It is designed to rotate about a rotation axis 8. It has a groove 10 that extends along the rotation axis 8 completely through the gearbox socket 2. It extends inward from the end face direction. After passing through approximately one-third of the axial thickness of half 4 or 6, an undercut 12 is provided, resulting in the formation of a cavity 14. A clamping frame 16 is arranged in the cavity 14 and is stressed by a compression spring 18 along the direction of the undercut 12.

[0036] like Figure 1 As shown, the undercut 12 is much more pronounced in the lower region of the drawing plane than in the upper region. In this case, the inclined surface 13 extending laterally to the rotation axis 8 is formed by the inner end face boundary surface 15. In the first spatial direction, this is at an angle α inclined with respect to the end face 20 of the gearbox socket 2, by which the drive element can be inserted into the cavity 14. The inclined surface 13 also causes the end face 20 to be inclined at another angle β in the second spatial direction. When the clamping frame 16 rests on the inner side, the end face boundary surface 15 and the normal 17 of the plane surface spanned by the clamping frame 16 are therefore inclined with respect to the rotation axis 8. This will be referred to below as the "first position". This position is the position adopted by the clamping frame 16 in the unloaded state because the compression spring 18 presses it inward, along the end face boundary surface 15. Figure 1 In the position shown, the surface normal 17 is parallel to the rotation axis 8. This will be referred to as the "second position" below.

[0037] The clamping frame 16 has a profile 22, which corresponds to the inner profile 24. Profiles 22 and 24 are flat in cross-section, for example, squares with rounded corners. This non-circular shape means that torque can be transmitted between the relevant axial halves 4 or 6 and the clamping frame 16.

[0038] Furthermore, the clamping frame has a centrally located opening 26, the center of which passes approximately through the rotating shaft 8. The opening 26 is designed to mate with a drive element (not shown). This drive element can be pushed through the groove 10 to the gearbox socket 2 and through the clamping frame 16. Because the clamping frame 16 is tilted due to the spring force acting on it, it rises slightly when the drive element is pushed in, bringing it closer to the second position. The opening 26 allows the drive element to be inserted and pushed in there. At rest, the clamping frame adopts the maximum possible angle with the end face 20, which depends on the drive element when it is pushed in.

[0039] The opening 26 is preferably designed to have a sharp edge, and is therefore designed to wed in the drive element. Pulling out the drive element creates a stronger wedgment, so that the drive element remains within the groove 10 and is virtually impossible to pull out. By inserting a slender tool into the cut 28 adjacent to the groove 10, the clamping frame 16 can be moved from the outside to a position substantially perpendicular to the axis of rotation 8. As a result, the edge of the opening 26 is released from the drive element, thus creating a wedgment effect, and the drive element can be pulled out of the groove 10.

[0040] The gearbox socket 2 has teeth 30 on its outer circumference for meshing with corresponding teeth of gearbox elements in the window gearbox or door gearbox. Additionally, a locking recess 32 is provided, which can be locked using a locking element (not shown here).

[0041] Figure 2a A portion of the window gearbox 34 is shown, with the gearbox socket 2 inserted into it. In Figure 2B, the window gearbox 34 is shown in its assembled state. A push rod 36 is provided here, which meshes with the teeth 30 of the gearbox socket 2. If the drive element is inserted into the recess 10, the gearbox socket 2 can rotate, thereby generating a linear pushing motion of the push rod 36.

[0042] In the radial direction, two locking elements 38 engage with locking recesses 32 in the gearbox socket 2, holding the gearbox socket 2 in a predetermined rotational position with a certain force. By applying sufficient torque, the locking elements 38 can be released from the locking recesses 32 and the gearbox socket 2 can continue to rotate. The user of the operating handle integrated into the gearbox socket 2 can identify the reached rotational position by sound and touch. The locking elements 38 are designed, for example, to be spherical, with each sphere radially compressed against the gearbox socket 2 by a compression spring 40.

[0043] Figure 3aAn operating handle 42 on a window sash 44 is shown, through which a window gearbox 34 can be used. The window sash 44 has a circular opening 46, through which a recess 10 can be accessed, for example. A cover ring 48 is provided to cover the edge of the opening 46, for example. No knot is required for connection to the drive element or locking function. The user only sees the cover ring 48 as the end.

[0044] The drive element 50 can be inserted through the cover ring 48 from the outside into the opening 46, thereby inserting into the groove 10 in the gearbox socket 2. The handle 52 can be connected to the drive element 50 so that operating the handle 52 drives the window gearbox 34.

[0045] exist Figure 3b In the middle, the operating handle 42 is completely fixed to the window sash 44. Figure 3c Tool 54 is visible and can be used to remove handle 52 from the drive element. Based on the fastening principle, tool 54 can be used to fasten handle 52, such as with countersunk screws.

[0046] Figure 4a and 4b Tool 54 is shown in the cut 28 for removing drive element 50 from gearbox socket 2. In this case, clamping frame 16 is moved to a position substantially perpendicular to the rotation axis 8, such as the second position, thereby eliminating the wedging effect of drive element 50. This is in Figure 4b This can be seen from the text.

[0047] Figure 5a A cross-sectional view of the gearbox socket 56 is shown, slightly modified from the gearbox socket 2 described previously. Furthermore, the housing component 58 is shown belonging to the window gearbox 34 and receiving the gearbox socket 56. This description differs from the previous one in that two clamping frames 16 are provided in this case, spaced axially from each other, and a compression spring 18 is surrounded between them. The recess 10, or cavity 14 of the gearbox socket 56, is designed such that inclined planes are formed at both front ends of the cavity 14. Therefore, the drive element 50 can be inserted and clamped from both end faces. Figure 5b The cavity 14, slightly modified to achieve this purpose, is shown. In this case, the two clamping frames 16 are each in their first position.

[0048] Figures 6a to 6d The drive element 50 is shown being fastened from both axial directions. (As shown) Figure 6a and 6bAs shown, the drive element 50 is clamped to the clamping frame 16, which is first pierced in each case. The opposing clamping frame 16, at its rear in the push-through direction, is secured in a second position by a pin 55 inserted into a corresponding transverse hole 53, wherein the clamping frame 16 in the second position is vertically arranged to the rotating shaft 8. Figures 6C and 6D show the drive element 50 being inserted from another direction, where the pin 55 is then arranged in another corresponding transverse hole 53.

[0049] The tool 54 is positioned in the corresponding free transverse hole 53 and rotated to move the clamping element 16 to a second position, wherein the tool is oriented vertically to the rotation axis 8 for disengaging this connection. Figure 7b and 7c This illustrates the case where pin 55 is inserted into transverse hole 53 to allow the drive element to be driven from the left ( Figure 7c Insert to the right ( Figure 7b ).

[0050] The present invention is not limited to one of the above embodiments, but can be modified in various ways. It can be seen that the operating handle for accessories such as windows and doors has at least one drive element that can engage with the handle for joint rotation, and a gearbox socket for integration into a window or door gearbox, wherein the gearbox socket has a groove extending through a rotation axis of the gearbox socket, and at least one spring-loaded blocking or clamping element pivotally mounted therebetween, which can engage with the drive element through force, form fit, and / or friction engagement. The gearbox socket has a radially inward locking recess on its outer circumference for receiving a locking element.

[0051] All features and advantages that appear in the claims, description and drawings, including structural details, spatial arrangements and method steps, are essential to the present invention, whether alone or in combination.
