AI Technical Summary
Existing quick-action pin connectors lack protection against increased tension, leading to uncontrolled tilting and poor force transmission, and require significant modifications to the driver element, limiting their use with standard square drives.
The locking and clamping elements are arranged in a parallelogram configuration, guided by bevels at angles other than perpendicular to the cross-sectional area, providing enhanced tensile strength and allowing for standard square drives without requiring modifications.
This arrangement significantly enhances tensile strength and stability, preventing uncontrolled interlocking and enabling easy disassembly, while maintaining compatibility with standard square drives.

Abstract
Description
The invention relates to a quick-action pin connection for structural elements, in particular for actuating handles, in order to connect a driver element / a square to a handle in a rotationally fixed manner.Such a quick-action pin connection is known, for example, from EP 1 683 933 B1, which describes a handle in which a driver element can be brought into non-rotatable engagement with a handle, wherein a device is provided between the handle and driver element, which device is designed such that insertion of the driver element into the handle can be effected in a first direction (R1) and is blocked in the opposite direction (R2). This is essentially achieved by tilting and clamping elements which are mounted in a tiltable manner on a beveled sleeve shoulder and are brought into engagement with the driver element or square, wherein these pivot either parallel or diagonally or have a diagonal pivot axis.The large night part of the prior art in quick-action pin connections as their lack of securing under increased tension and that the blocking and tilting elements can tilt randomly into one another, which also makes disassembly more difficult. The lack of guidance also leads to a lack of force introduction.Even in the more recent prior art as with DE202022102518 (U1), which shows the device with a freewheel group and a spindle, the device is not secured against tension and pressure, but expressly only against tension and slip. However, the great disadvantage here is above all that considerable changes must be made to the driver element and a square piece according to the standard can no longer be used.Reinforced protection against tension is required in particular when assembling the newer handles that are axially displaceable and / or lockable on one side by tension, since tension must be repeatedly exerted, for example, for locking the door. Such handles are seen with their prior art in 20 2021 106 925.2 and 20 2023 101 565.4.In particular, EP 1 683 933 B1 does not solve this problem. It can be seen here that the blocking or clamping elements lie in a space which consists of a support bevel and a sleeve base which lies perpendicular to the cross-sectional surface. However, the options which result from a change in the device base or head for introducing force are not used in this case.The object existing in the prior art is achieved by an actuating handle or a device according to the patent claims. The main features are found in the characterizing part of claim 1 and claims 2-5 form advantageous embodiments.The above embodiments have the particular disadvantage that locking and clamping elements are not guided but, as in EP 1 683 933 B1, are open in a sleeve, which during assembly leads to the locking and clamping elements being caught in one another and the device not being able to be pulled off the square.It has been found that the object for reinforcing the tensile strength is achieved by guiding the blocking and clamping elements in a parallelogram. Even a very small pivoting of the inclined surfaces leads to a substantially improved tensile strength, wherein, among other things, the use of more heavily loaded springs can be avoided.Even a small change of the surface otherwise perpendicular to the driver element to a slope directly leads to a substantial increase in the stability of the device and driver element.This object is achieved by a guide of claims 6 - 9 in that the locking and clamping elements are arranged in a space considered from the side view. This is particularly advantageous.Reference Number:1 Actuating handle 2 Handle 3 Driver element 4 Device 5 Locking / clamping element 6 Force / spring 7 Guide 8 Slopes 9 Space (surrounded by slopes, parallelogram) 10 Sleeve / container 11 DepressionThe figures show preferred embodiments of the invention: FIG. 1 shows, by way of example, a device (4) according to the invention mounted in a door handle assembly / actuating handle (1) and introduced into a door handle (2), wherein the movement directions R1 & R2 of the driver element (3) to be mounted in a rotationally fixed manner are evident and the basic structure of the device (4) consisting of the locking and clamping elements (5) and the acting spring force (6). In this case, one door handle (2) is introduced into the other door handle through a through hole in the door with the opposing handle (2) with the device (4) in the direction R 1 and locked in R 2 when the introduction depth is reached. The clamping elements are designed to be releasable, for example by means of a small tool which can be passed through one or two openings. As a result of the solution, the driver element (e.g. a square) can also be moved into R 2. The arrangement of the clamping elements ensures a protection against tension. FIG. 2 shows the device ( 4) according to the invention with a through opening and the driver element ( 3) and shows the direction of movement R 1. Here it becomes clear how the spring (6) is suitable for applying pressure to the locking and clamping elements which can be released, for example, by lifting. By lifting the locking and clamping elements from the inclined surfaces, the solution can be achieved. It is shown how the position of the top end of the device / guide (4) can deviate from the rectangular position in the prior art. FIG. 3 shows the prior art ( 4) with a through opening and the driver element ( 3) and shows the direction of movement R 1. It is shown how the position of the upper end of the device / guide (4) is made different from the rectangular position in the prior art in order to arrive at the device according to the invention, wherein a change can already take place in small steps / increments in order to achieve an adjustment and improvement of the tensile strength. FIG. 4 shows the device / guide (4) alone in a three-dimensional representation, wherein the guide / rails (7) can be seen, which prevents an unordined locking / interlocking of the locking and clamping elements (5). The blocking and clamping elements can have depressions (11). FIG. 5 shows the device (4), wherein particularly the inclined surfaces (8) and the parallelogram-like space (9) are well visible. The inclined surfaces serve on the one hand as tilting points and as bearing surfaces for the blocking and clamping elements (5). Furthermore, the arrangement of the blocking and clamping elements (5) and the spring (6) can be seen in a sequence of spring (6) and blocking and clamping element(s) (5). All enclosed by space as a parallelogram. Here, a symmetrical space definition can be selected, but the inclined surfaces can also be offset relative to one another in space. It is equally possible to give off the symmetrical space definition and to offset the inclined surfaces relative to one another. FIG. 6 shows the device (4), wherein in particular the inclined surfaces (8) and the parallelogram-like space (9) or the space as parallelogram (9) are again easily visible. Here, the angle of attack of the surfaces is not very pronounced, but this leads to the desired application-specific improvement in the tensile strength. FIG. 7 shows the device (4), wherein in particular the inclined surfaces (8) and the parallelogram-like space (9) or the space as parallelogram (9) is again easily visible. The inclined surfaces serve on the one hand as tilting points and as bearing surfaces for the blocking and clamping elements (5). Furthermore, the arrangement of the blocking and clamping elements (5) and the spring (6) can be seen in a sequence of spring (6) and blocking and clamping element(s) (5). In this embodiment, the angles of attack are strongly pronounced. FIG. 8 shows the device (4), wherein the inclined surfaces (8) are visible in a different trapezoidal position. Furthermore, the arrangement of the blocking and clamping elements (5) and the spring (6) can be seen in a sequence of spring (6) and blocking and clamping element(s) (5). In this embodiment, the angles of attack are arranged antiparallel. FIG. 9 illustrates the guide / rails ( 7) and their important role in the targeted guiding of the blocking and clamping elements in space. Furthermore, depressions (11) are shown for engaging the guide in the locking and clamping elements. FIG. 10 shows the advantages of the invention as in FIG. 9, except that the arrangement of the blocking and clamping elements ( 5) and the spring ( 6) is also shown in a sequence of the blocking and clamping element ( 5), spring ( 6), blocking and clamping element(s) ( 5).The invention is further embodied. The invention set forth in claim 1 shows an actuating handle (1) for structural elements such as windows, doors and the like, having at least one handle (2) and having a driver element (3) which can be brought into non-rotatable engagement with the handle (2), wherein a device (4) is provided between the handle (2) and the driver element (3), which device is designed such that the introduction of the driver element (3) into the handle (2) can be effected in a direction (R1). Compared to the prior art, the special feature now has an increased tensile strength, wherein the device (3) has at least one blocking or clamping element (5) which can be brought into frictional engagement with the driver element (3) by force, form and / or friction, wherein blocking or clamping elements (5) are present which are subjected to a permanent force in one direction (R 2), wherein the device (4) is fixed or fixable in the handle. The blocking and clamping elements (5) are located in a space with opposite slopes, wherein both opposite slopes (8) do not run perpendicular to the cross-sectional area of the driver element, as in the prior art, but the position of the slopes lies at a different angle. In principle, any angle is possible here which still allows a polygonal or round driver element to be passed through. The angular range of 70°-110° in relation to the cross-sectional area has been found to be optimum. Functionally, this achieves that the device ( 4) produces an increased tensile strength. The further advantage is that the tensile strength can be metered with different embodiments.It has been found to be particularly advantageous to guide the blocking and clamping elements in a parallelogram or to form a parallelogram-like space by the slopes.It is advantageous to introduce the blocking or clamping elements (5) into a sleeve / container (10).The blocking or clamping elements (5) can be actuated or activated axially or radially by a driver element (3) moved in directions R1 and / or R2.It is also advantageous that the blocking or clamping elements (5) are supported on one or more slopes (8). In addition, the blocking or clamping elements (5) can be supported on one or more slopes (8) and the blocking and clamping elements (5) can be pivotably mounted.A pivot axis configuration can be configured as follows:The blocking or clamping elements (5) can be supported on one or more slopes (8) and the blocking and clamping elements (5) can be pivotably mounted and the pivot axis of the blocking or clamping element (5) lies diagonally to the cross-sectional area of the driver element. The blocking or clamping elements (5) can be supported on one or more slopes (8) and the blocking and clamping elements (5) can be pivotably mounted and the pivot axis of the blocking or clamping element (5) lies parallel to the cross-sectional area of the driver element (3).Furthermore, the blocking or clamping elements (5) can be supported on opposite slopes (8), wherein an arrangement offset in space is also possible.The invention is also particularly well suited for the case where the actuating handle ( 1) is designed to be axially displaceable.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
