Description

Driving handle for door and window without rosette

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

Many variations of operating handles for operating doors and windows are known in the art. They usually have a drive which can move an operating device in the sash or door leaf, for example a window gear box via a handle. For example, the driver may have a square design.

In order to open and close a window or door, in addition to the rotational movement, a pulling or pushing force must be transmitted from the handle to the sash or door leaf. The connection between the handle and the drive is thus designed such that the two are axially connected in a non-rotatable manner after assembly.

It is known to implement operating handles without rosettes on the window and door leaves. However, this results in a very limited installation space.

For example, an operating handle is known from EP 168393 B1, wherein by pushing the driver element into the handle, the driver element can be fixed in the handle by means of a blocking or clamping element.

It is an object of the present invention to make an operating handle with a particularly convenient and fast action for fixing a driver to an operating device in a window or door leaf, wherein the operating handle can be realized simultaneously without the need for a rosette. Preferably, the locking function is achieved simultaneously.

The main features of the invention are set out in the characterizing part of claim 1. The subject matter of claims 2 to 12 is an embodiment.

The invention proposes an operating handle for components such as windows, doors and the like, having at least one drive element which can be engaged with the handle for joint rotation and a gear box socket for integration in a vehicle window gear box or a vehicle door gear box. The invention is characterized in that the gearbox socket has a recess extending through the rotational axis of the gearbox socket, and at least one spring-loaded blocking or clamping element which can be pivotally mounted therein, wherein the blocking or clamping element can be force-fitted, form-fitted and/or frictionally engaged with the drive element, and the gearbox socket has a radially inwardly oriented latching recess on its outer circumference for receiving the latching element.

According to the operating handle of the invention, the different functions provided for achieving the above-mentioned objects are integrated directly into the gearbox socket.

The gear box receptacle is an assembly that is mounted in a window gear box, or the like, to drive the different elements therein. In this case, the gearbox socket preferably has an external toothing, for example in engagement with a toothed rack or other corresponding toothing element. If the gearbox socket is rotated by the drive element, the window gearbox is thus also moved. The gearbox socket may be fully integrated into the window gearbox and thus be located fully in the corresponding sash or door leaf.

The gearbox socket has a recess that preferably extends completely through the gearbox socket in an axial direction. A drive element is provided through the recess to establish a connection therein for joint rotation of the gearbox socket. For this purpose, at least one blocking or clamping element is provided in the recess and is designed to establish a connection with the driver element by pushing in the driver element. This is preferably achieved as described in EP 1683933 B1, since the driver element is inserted into the recess, where it engages with the blocking or clamping element in order to interconnect them. Due to the spring-loaded mounting, the blocking or clamping element allows a change of direction upon insertion of the driving element, so that the two elements can follow the movement of the driving element for mutual engagement. At the same time, wedging of the locking or clamping element with the driving element may prevent pullout. Since blocking or clamping elements are provided in the gearbox socket, no knots or other elements that increase the installation space need to be provided, which elements protrude outwards through the door leaf or window sash. However, a secure connection may be established between the drive element and the window gear box.

The locking function can also be achieved by a gearbox socket having a locking recess on the circumference. For example, a spring-loaded locking device can be provided in the window gear housing, which is guided radially to the gear housing socket by means of a spring force and presses against its circumference. The latching recess allows selective engagement between the latching means and the latching recess, which results in a re-release of the latching force by applying sufficient torque to the driver element. The release force or release torque can be set by the dimensions of the locking means, the latching recess and the spring force.

The integration of such a device for connecting the drive element to the window gear box and the locking function in the gear box socket results in a particularly simple, compact and complete integration in the window sash or door leaf. A separate connection or locking means outside the sash or door leaf is not necessary and the operating handle according to the invention may be designed completely without rosettes. No modification to any opening or cutout in the window or door leaf is required, provided that the gearbox socket does not exceed custom, specified and/or standardized dimensions.

In a preferred embodiment, the gearbox socket is divided into two axial halves, the recess extending into both halves. The groove may 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, a shoulder or edge may be implemented in the groove against which the blocking or clamping element may enter the abutment. Once the blocking or clamping element is inserted into the gearbox socket, the two halves may be axially screwed or glued together.

In an advantageous embodiment, the recess has an undercut to fix the blocking or clamping element. The groove may have undercuts from both axial directions, so that the diameter of the groove increases abruptly, at least at one point, inwardly in the axial direction. Two jumps of this diameter may be provided, spaced apart from each other, opposing the undercuts to each other and forming a cavity for receiving the blocking or clamping element. The two undercuts then preferably have a symmetrical design and are arranged symmetrically to each other.

In an equally advantageous embodiment, the blocking or clamping element has a clamping frame with an opening matching the contour of the drive element for receiving and closing the drive element. The driving element may extend through the opening of the clamping frame. Due to the rotatable spring-loaded mounting, the clamping frame can be oriented obliquely to the drive element after insertion of the drive element-depending on the size of the drive element opening. In particular when the opening has a clear contour, the clamping frame may be wedged by the driving element when the direction of movement of the driving element is reversed. The clamping frame can be designed as follows: if the application of force in the opposite direction is continued, the clamping frame is positioned more obliquely in order to remove the driving element, so that the two elements become more wedged together.

The clamping frame facilitates rotation between a first position in which a surface normal of a plane spanned by the clamping frame extends obliquely to the rotation axis and a second position in which the surface normal runs parallel to the rotation axis. The pivot axis may run perpendicular to the axis of rotation and thus extend transversely across the longitudinal axis of the driver element. For example, the pivot may be inclined across the cross-sectional area of the driver element. Thus, when the clamping frame is positioned obliquely, the clamping frame may wedge on two mutually adjacent surfaces of the driver element. The driver element may be guided through if the clamping frame is at least for the most part in the second position. The clamping frame is preferably always forced into the first position due to the spring-loaded mounting, but is forced into the direction of the second position due to the drive element being pushed through.

In addition, the recess may have an inclined inner end boundary surface against which the clamping frame may closely abut to occupy the first position. Thus, when the driver element is not inserted, the gearbox socket is in a state allowing pushing in the driver element, since the driver element always lightly presses the clamping frame under spring force, so that the driver element can slide through the opening of the clamping frame. However, from this process, the clamping frame is oriented as obliquely as possible. The direction in the neutral state can be ensured by a suitably designed inner end face boundary surface.

In a further advantageous embodiment, the profile of the clamping frame is designed to match the inner profile of the recess. Thus, the clamping frame fills the inner contour of the groove. If the profile is not circular, it can transmit torque. The dimensions between the clamping frame profile and the groove inner profile are slightly different, which means that the clamping frame can be rotated sufficiently.

Furthermore, it is advantageous if at least one blocking or clamping element has two clamping frames, between which a compression spring is arranged. In each case, the drive element can then be wedged into one of the two clamping frames, depending on the direction in which it is inserted into the gearbox socket. It is therefore suitable for use immediately after installation, both counter-clockwise and clockwise. There is no need to check the direction and turn the gearbox socket prior to installation into the window gearbox.

If two clamping frames are used, the recess preferably has two inner end surface boundary surfaces which face each other and run in mirror-inverted fashion, in each case one of the clamping frames being able to closely follow the surface in order to adopt its first position. The clamping frame and the driving element are reliably wedged by mounting from two directions. Furthermore, the driver element can be inserted into the gearbox socket from two directions, so that it is not necessary to rotate the gearbox socket. In this case, the pin can be inserted laterally from the outside into the gearbox socket via a lateral hole, laterally to the rotation axis, in order to move one of the two clamping frames (which later should be in an inactive state) to the second position, so that the driver element can be slid over and permanently fixed there. The surface normal of the plane spanned by the clamping frame is then parallel to the rotation axis, wherein the clamping frame is held stationary. The opening of the clamping frame is aligned with the drive element and does not counteract axial movement of the drive element. After the drive element is pushed through, the clamping frames act only as a basis for the compression springs located between the clamping frames.

Thus, in an advantageous embodiment, the gearbox socket has two transverse holes in which pins can be inserted in order to vertically fix one of the clamping frames to the rotation shaft in each case.

In a particularly advantageous embodiment, the gearbox socket has a cutout arranged along the recess for the passage of a tool, wherein the tool is used to move the blocking or clamping element against the spring force. The tool may be an elongate member which is inserted through a cutout in the gearbox socket and into the abutment together with the blocking or clamping member therein. It can then be moved under the action of a spring force accordingly to release the wedging with the drive element and thereby release the drive element again. The size of the cut-out may be much smaller than the recess. For example, it may be only 3mm or less in width for insertion of a suitable tool, such as a thin screwdriver or thin wrench. The cut-out may be arranged at the edge of the groove. A space may be provided between the recess and the slit, but this is not required.

In a further advantageous embodiment, the latching depressions are uniformly spaced apart from one another in the circumferential direction. The space between the latching depressions depends on the desired latching position. It is conceivable that at least three locking positions, 45 deg. apart from each other, are integrated to signal the position of the handle for a closed, fully open or tilted window.

Furthermore, it is advantageous if the locking recess has a contour of a circular segment. In particular, the spherical or spherical segment-shaped blocking element can engage with the blocking recess and be released therefrom again reliably. In addition to the spring force acting on the locking element, the segment height or the central angle of the locking recess contour can also determine the holding force of the locking element in the locking recess.

Further features, details and advantages of the invention result from the wording of the claims and from the description of exemplary embodiments with reference to the drawings. In the drawings:

Fig. 6a to 6d show the insertion of the drive element into the gearbox socket from two directions.

Fig. 7a shows the gearbox socket during release of the drive element.

Figures 7b and 7c illustrate the insertion of a pin into one of the transverse holes of the gearbox socket.

Fig. 1 shows a gear box socket 2 for integration into a window gear box or a door gear box. The gearbox socket 2 has two axial halves 4 and 6 which, when put together, form the body of the gearbox socket 2. Which is intended to rotate about a rotation axis 8. It has a recess 10, which recess 10 extends completely through the gearbox socket 2 along the rotation axis 8. It expands inwardly from the end face direction. After passing through approximately one third of the axial thickness of the half-portions 4 or 6, an undercut 12 is provided, which results in the formation of a cavity 14. The clamping frame 16 is arranged in the cavity 14 and is forced in the direction of the undercut 12 by a compression spring 18.

As shown in FIG. 1, the undercut 12 is much more pronounced in the lower region of the plane of the drawing than in the upper region of the plane of the drawing. In this case, the inclined surface 13 extending transversely to the rotation axis 8 is formed by an inner end surface boundary surface 15. In the first spatial direction, this is at an angle inclined by α to the end face 20 of the gearbox socket 2, through which the driver element can be inserted into the cavity 14. The plane 13 also tilts the end face 20 by another angle β in the second spatial direction. When the clamping frame 16 is resting on the inside, the end face boundary surface 15 and the plane surface normal 17 spanned by the clamping frame 16 are thus inclined to the rotation axis 8. Hereinafter, this will be referred to as "first position". This position is the position of the clamping frame 16 which is used in the unloaded state, since the compression spring 18 presses it on the inside, the end face boundary surface 15. In the state shown in fig. 1, the surface normal 17 is parallel to the rotation axis 8. Hereinafter, this will be referred to as "second position".

The clamping frame 16 has a contour 22 which corresponds to an inner contour 24. The profiles 22 and 24 are flat in cross-section, for example square with rounded corners, which non-circular shape means that torque can be transmitted between the associated axial half 4 or 6 and the clamping frame 16.

Furthermore, the clamping frame has a centrally arranged opening 26, the center of which approximately passes through the rotation axis 8. The opening 26 is designed to mate with a driving element (not shown). The drive element can be pushed through the recess 10 to the gearbox socket 2 and through the clamping frame 16. Because the clamping frame 16 is positioned obliquely due to the spring force acting thereon, it is slightly raised when the driver element is pushed in, bringing it closer to the second position. The opening 26 allows the driver element to be inserted and pushed there. At rest, the clamping frame adopts the largest possible angle with the end face 20, which angle depends on the driving element when it is pushed in.

The opening 26 is preferably designed with sharp edges and is thus designed to wedge into the driving element. Pulling out the drive element may result in a stronger wedge so that the drive element remains within the recess 10 and can be pulled out only little. By inserting the elongated tool into the cutout 28 adjacent the recess 10, the clamping frame 16 can be moved from the outside to a position substantially perpendicular to the rotation axis 8. As a result, the edges of the opening 26 are released from the drive element and thus a wedging effect is created and the drive element can be pulled out of the recess 10.

The gear box socket 2 has teeth 30 on its outer circumference for engagement with corresponding teeth of a gear box element in a window gear box or a door gear box. Furthermore, a locking recess 32 is provided, which can be locked using a locking element (not shown here).

Fig. 2a shows a part of a window gearbox 34 into which the gearbox socket 2 is inserted. In fig. 2B, the window gear box 34 is shown in an assembled state. Here a push rod 36 is provided which engages with the teeth 30 of the gearbox socket 2. If the driving element is inserted into the recess 10, the gearbox socket 2 can be rotated, resulting in a linear pushing movement of the push rod 36.

In the radial direction, the two latching elements 38 engage with latching recesses 32 in the gearbox socket 2, so that the gearbox socket 2 is held in a predetermined rotational position with a certain force. By applying sufficient torque, the latching element 38 can be released from the latching recess 32 and the gearbox socket 2 continues to rotate. The user of the operating handle integrated gearbox sleeve 2 can recognize by sound and touch that certain rotational positions have been reached. The blocking elements 38 are for example designed as balls, each ball being radially compressed on the gearbox socket 2 by a compression spring 40.

Fig. 3a shows an operating handle 42 on a window sash 44, wherein window mechanism 34 may be used. The sash 44 has a circular opening 46 through which the recess 10 is accessible, for example. For example, a cover ring 48 is provided to cover the edge of the opening 46. Neither the connection to the drive element nor the locking function requires a knot. The user only sees the cover ring 48 as a tip.

The drive element 50 can be inserted from outside the cover ring 48 through the cover ring to the opening 46 and thus into the recess 10 in the gearbox socket 2. The handle 52 may be connected to the drive element 50 such that operating the handle 52 drives the window gear box 34.

In fig. 3b, operating handle 42 is fully secured to window sash 44. Fig. 3c shows a tool 54 with which the handle 52 can be detached from the drive element. The tool 54 may be used to tighten the handle 52 according to the tightening principle, such as with countersunk screws.

Fig. 4a and 4b show the tool 54 in the cutout 28 for removing the drive 50 from the gearbox socket 2. In this case, the clamping frame 16 is moved to a position substantially perpendicular to the rotation axis 8, such as the second position, so that the wedging effect of the driving element 50 is also eliminated. This can be seen in fig. 4 b.

Fig. 5a shows a cross-sectional view of the gearbox socket 56, slightly modified compared to the gearbox socket 2 described previously. In addition, the housing member 58 is shown as belonging to the window gear box 34 and receiving the gear box receptacle 56. This description differs from the previous description in that in this case two clamping frames 16 are provided, which are axially spaced from each other and enclose a compression spring 18 between them. The cavity 14 of the recess 10 or the gearbox socket 56 is designed such that a bevel is formed at both front ends of the cavity 14. Thus, the driving element 50 can be inserted and clamped from both end directions. Fig. 5b shows a cavity 14 which is slightly modified for this purpose. In this case, the two clamping frames 16 are each in their first position.

Fig. 6a to 6d show the fastening of the drive element 50 from two axial directions. As shown in fig. 6a and 6b, the drive element 50 is clamped to the clamping frame 16, the clamping frame 16 being pierced in each case first. Opposite clamping frames 16, which are fixed in a second position by pins 55 at the rear in the push-through direction, the pins 55 being inserted into the respective transverse holes 53, wherein the clamping frames 16 are arranged vertically to the rotation shaft 8 in the second position. Fig. 6C and 6D show the insertion of the drive element 50 from another direction, wherein the pins 55 are then arranged in other corresponding transverse holes 53.

The tool 54 is located in the corresponding free transverse hole 53 and rotated in order to move the clamping element 16 into the second position, in which the tool is oriented perpendicularly to the rotation axis 8 for releasing this connection. Fig. 7b and 7c show the insertion of the pin 55 into the transverse hole 53 in order to insert the driving element from the left (fig. 7 c) to the right (fig. 7 b).

The present invention is not limited to one of the above embodiments, but may be modified in various ways. It can be seen that an operating handle for fittings such as windows, doors and the like has at least one drive element which can be engaged with the handle for joint rotation and a gear box socket for integration in a vehicle window gear box or a vehicle door gear box, wherein the gear box socket has a recess extending through the rotational axis of the gear box socket and at least one spring-loaded blocking or clamping element pivotally mounted therebetween which can be force-fitted, form-fitted and/or friction-engaged with the drive element, the gear box socket having radially inward latching recesses on its outer circumference for receiving the latching elements.

All features and advantages, including structural details, spatial arrangements and method steps, which appear from the claims, the description and the drawings, are essential to the invention, both individually and in various combinations.
