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. In this prior art, the blocking and clamping elements lie in a space which is designed as a right-angled trapezoid.This construction has the disadvantage, among other things, that a continuous adjustment, for example adapted to different door leaf thicknesses, is not possible, but must be preset. Furthermore, the stability must be increased in that the quick-action pin connection can be effected not only in one direction (R 1) and locked in the opposite direction (R 2), but can be effected in both directions (R 1 & R 2) and can be locked in both directions (R 1 & R 2) respectively, but also.The large night part of the prior art in pin quick connections as their lack of protection on tension and on compression. The quick-action pin connection mentioned by way of example with EP 1 683 933 B1 produces only a protection against tension.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.A protection against tension and pressure is required in particular when assembling the newer axially displaceable handles and / or handles lockable on one side by tension, since tension and pressure must be exerted, for example, for locking. Such handles are seen with their prior art in 20 2021 106 925.2 and 20 2023 101 565.4.Furthermore, the prior art does not offer the possibility of making the force introduction to the driver element flexible.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 - 19 form advantageous embodiments.In connection with the above-mentioned. The guide for locking and clamping elements according to the invention stands from claim 21. EP 1 683 933 B1, US3441303 and US3468579 show devices in which locking and clamping elements are present in a sleeve or in a housing, which are clamped with the driver element during tilting due to the spring force. US3468579 teaches here that it is advantageous to make the clamping elements softer than the driver element in order to achieve better friction / adhesion.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.This object is achieved by a guide of claims 20-26 in that the locking and clamping elements are arranged in a trapezoidal / trapezoidal space considered from the side view. In this respect, a space with the greatest possible non-equal sides trapezoidal has proven to be particularly advantageous. The variation of all angles makes it possible to control the introduction of force variably as required and to respond to the locking and clamping elements. Thus, inter alia, it is possible to react to a variation of the driver elements, for example in the form of a edged or round.Reference Number:1 Actuating handle 2 Handle 3 Driver element 4 Device 5 Locking / clamping element 6 Force / spring 7 Guide 8 Slopes 9 Trapezoidal / trapezoidal space 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 in the trapezoidal space according to the invention ensures protection against tension and shear. 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 & R 2. 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. FIG. 3 shows the continuous movement in the directions R 1 and R 2 of the device ( 4) which encloses the driver element ( 3). FIG. 4 shows the device / guide (4) alone, wherein the guide / rails (7) can be seen, which prevents disordered locking / interlocking of the locking and clamping elements (5). The blocking and clamping elements can have depressions (11). The blocking and clamping elements are located in a space which is trapezoidal in unequal sides. FIG. 5 shows the device (4), wherein particularly the inclined surfaces (8) and the space (9) with an irregular triangle shape are 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 the blocking and clamping element (5), spring (6) and again the blocking and clamping element (5). Everything is enclosed by the space which assumes trapezoidal shape with unequal sides. The inclined surfaces are also offset relative to one another in space. FIG. 6 shows the device (4), wherein in particular the inclined surfaces (8) and the space (9) with an irregular triangle shape are also 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 the blocking and clamping element (5), spring (6) and again the blocking and clamping element (5). Everything is enclosed by the space which assumes trapezoidal shape with unequal sides. Here, the space is made almost equal to a right-angled trapezoid, but without falling back into a disadvantageous embodiment of the prior art and thus nevertheless providing a protection against tension and pressure. The inclined surfaces can also be offset relative to one another in space. FIG. 7 shows the device (4), wherein in particular the inclined surfaces (8) and the space (9) with an irregular triangle shape are also 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 the blocking and clamping element (5), spring (6) and again the blocking and clamping element (5). Everything is enclosed by the space which assumes trapezoidal shape with unequal sides. Here, the space is made almost equal to an isosceles trapezoid, but without falling back in the disadvantageous embodiment of the prior art and nevertheless offers a variable protection against tension and compression. The inclined surfaces can also be offset relative to one another in space. FIG. 8 shows the device with the guide (7) being raised by rails which can engage in depressions (11) of the blocking and clamping elements (5) in order to ensure the guide (7).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 is that the driver element is lockable and releasable in at least two directions (R1 & R2), wherein the device (3) has at least one locking or clamping element (5) which can be brought into frictional engagement with the driver element (3) by force, form and / or friction, wherein locking or clamping elements (5) are present which are acted upon by a permanent force (6) simultaneously or alternately (R1 & R2) in the respective opposite direction or which issue the permanent force (6) therefrom, wherein the device (4) is fixed or fixable in the handle. Functionally, this ensures that the device ( 4) is moved back and forth adjustably on the driver element. Of course, the blocking and clamping elements must be released before the movement. The further advantage is that the door handle is secured both against tension and pressure by the locking and clamping elements engaging against one another. Thus, the mobility / flexibility during assembly, which is easy to control, is a side improvement in stability, which cannot be achieved in this way in the prior art. The device is designed such that it can be introduced into a handle ( 2). The blocking or clamping elements are designed with an opening which is just large enough to enclose the driver element, for example a square, and to enter into friction with the latter. It is advantageous to allow the spring force to be applied over the full surface of at least two blocking or clamping elements, i.e. a spring element should be used which acts simultaneously in the direction R1 & R2. In this case, the force introduction can be designed variably by the space of non-isosceles trapezoid type.Claim 2 presents the feature of continuously variable adjustment and release. It is possible to configure the device according to claim 1 such that after insertion it is no longer adjustable and detachable in order to optionally only enter into the advantage of tensile and compressive stability. However, the actuating handle shown can be used with a wide variety of door thicknesses precisely because of its continuous adjustability on the driver element. The continuous locking and release capability thus represents a further advantage to be taken up.Claim 7 extracts the very important application of the axially displaceable door presser fittings. These require an increased, also variable, compression and tension stability, especially due to the type of operation thereof, since the door lock is precisely guided by an axial movement.Claim 8 teaches that the spring force can be replaced by a resilient deformable plastic. However, it is also conceivable to use a plastic or an equivalent material which exerts a permanent force such as a spring.Claim 10 shows a preferred embodiment in which the device is provided with a guide of the locking and clamping elements (5). This produces a linear guide which in particular maintains the function of the device and ensures that easy releasability as a function remains at all times.Claim 15 introduces that the blocking or clamping elements (5) are supported on one or more slopes in order to ensure pivotability, claim 16 then introduces the preferred pivotable mounting.Claims 17 and 18 deal with the direction of pivoting of the locking and clamping elements about the driver element. A diagonal pivoting to the cross-sectional area of the driver element is proposed, and a parallel pivoting to the cross-sectional area of the driver element.Claim 20 then discloses a guide / device (4) in which the locking or clamping element advantageously lies in a trapezoidal space.Claim 24 then discloses the formation of the trapezoidal space by guide rails and inclined surfaces.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.
