EP1683933B1 - Actuation handle - Google Patents

Description

The invention relates to an actuating handle for components such as windows, doors and the like.

Actuation handles are known in numerous embodiments. They serve, for example, for opening and closing a window, a door or the like, wherein a handle is usually provided via a driver, e.g. a square pin, is designed for rotational entrainment of an actuator in the window or door, such as a window gear or a Schloßnuß.

In addition to the torque, the driver usually also has to transmit axial tensile forces, e.g. in door fittings. The connection between the handle and driver must be designed so that both are axially and rotatably anchored to each other after assembly, which - depending on the design of the window or the door - an adaptation of the pin connection to the respective thickness of the window frame or the door leaf be possible got to.

DE-U1-1 927 916 or DE-U1-1 937 220 use this two-part square pins, wherein at the ends of both pin halves wider notches with wedge surfaces are formed, which narrow in two directions and engages between the one expansion screw. The elongated formation of the notches allows in the axial direction a variable fixing of the square pin and thus an adaptation to the respective door thickness. However, the screwed into the handle neck expansion screw can protrude from the handle, which is aesthetically unsatisfactory and can lead to injury. In addition, the production cost is relatively high, because for each square pin a right and a left half of the pen is needed; Production and warehousing are therefore charged twice. The assembly is complicated and not possible without tools.

DE-U1-86 05 427 used for a door handle connection a specially designed threaded pin, which acts on outer edges above longitudinal grooves of two similar Vierkanthälften and pressed when screwing in between. The onion-headed tip of the threaded pin is supported in a V-shaped cavity on displaced material of the four-square halves. Again, a separate joining and assembly process is necessary for the determination of the driver in the handle, the strength of the connection depends on the proper determination of the threaded pin. This destroys the surfaces and edges of the Vierkanthälften sustainable, so that a repeated assembly is only partially possible. In addition, the four-square halves can move against each other under heavy load, so that a permanent Axialbefestigung is not always guaranteed.

Use other solution to improve the axial strength and to bridge manufacturing tolerances solid profile square pins in conjunction with slotted leaf spring elements or with corrugated spring elements (see eg DE-A-2 024 652 ). In EP-B1-0 436 795 the connecting pin on a side surface has a continuous longitudinal groove and end a blind hole with shoulders for supporting the angled ends of an elongated leaf spring. The longitudinal groove in the square pin facilitates the penetration of the fastening screw in an end present leaf spring longitudinal slot, which is narrower than the end-side thickening of the fastening screw. The attachment is replaced by a special voltage, the corrugated area of the leaf spring holding the connecting pin in the lock nut axially. Such a compound is also expensive to manufacture and in storage. When assembling several components must be joined, with the right tool must always be available.

The aim of the invention is to overcome these and other disadvantages of the prior art and to provide an actuating handle, which allows a permanently reliable connection between the driver and handle and without any tool can be mounted. The connection should adapt to different frame and wing thicknesses and withstand even increased loads permanently. The aim is also a cost-effective, disassemblable if necessary construction and ease of use. In addition, the reusability after repeated disassembly should be guaranteed.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 17.

In an actuating handle for components such as windows, doors and the like, with at least one handle and with a driver element, which is rotatably engageable with the handle engageable, wherein between the handle and the driver element, a device is provided, which is designed such that the insertion of the driver element in the handle in a first direction effected and locked in the opposite direction, wherein the device comprises at least one locking or clamping element, the force, shape and / or frictionally engageable with the driver element, wherein the locking or clamping elements in the opposite direction from a permanent force, which is a spring force, are applied, wherein the locking or clamping element is at least one clamping frame which surrounds the driver element, wherein the locking or clamping element is arranged in a sleeve and the sleeve is fixed or fixable in the handle, and wherein the Locking or clamping element is pivotally mounted, the invention provides that the pivot axis of the locking or clamping element is located diagonally to the cross-sectional area of the driver element.

This makes it possible to mount the actuating handle as easily as quickly without any tools. The driver, usually a square pin, is merely - as usual - introduced into the handle. However, a withdrawal in the opposite direction is then no longer possible because the device acts as a locking device and fixes the driver in the handle. It is irrelevant how far you introduce the driver in the handle. Once the locking device has detected the driver, this is - preferably in the axial direction - fixed and can not be pulled out of the handle again first. Different door thicknesses or window frame profiles are automatically taken into account, i. E. the handle is merely plugged up to the stop and then rests without wobble on its stop plate or on the respective component. The device fixes the driver in the handle so that the actuating handle can withstand high loads permanently. Accidental release or loosening is not possible. The square pin is neither noticeably damaged nor deformed when setting, so that the reusability is guaranteed after disassembly.

Fig. 1 shows an actuating handle 10 with a device 40 which is designed such that the insertion of the driver element 30 in the (not shown) handle 20 is effected in a first direction R1, while the withdrawal of the driver element 30 from the handle 20 in the opposite direction R2 is locked immediately. This embodiment is not covered by claim 1, because the pivot axis of a clamping frame runs parallel to one of the side surfaces of the driving element here. It is therefore not a part of the invention, but the prior art, which, however, facilitates the understanding of the invention.

A sleeve 150 is fixedly mounted with a cylinder jacket 52 in the recess 25 in (also not shown) handle neck 23 of the handle 20, preferably screwed. The axially raised, flange-like collar 55 is supported by a collar 48 at an upper step 21 in the handle neck 23 so that a grip collar 24 is formed above the handle neck 23.

The collar 55 has laterally extending transversely to the longitudinal axis A recess 45 in which an approximately annular clamping frame 71 is inserted like a drawer and with play. The frame 71 has centrally an angular recess 73, which is congruent to the recess 44 in the collar 55 and the inside width at least in the longitudinal direction of the recess 45 is greater than the cross-sectional dimension of the square pin 30. transverse to the longitudinal axis A and parallel to a side surface 32 of Square pin 30 is formed on the clamping frame 71, a support edge 75 which is slightly raised relative to the frame top 77 in the axial direction A and which has been produced, for example, by cranking. The clamping frame 71 is supported Thus, on one side of the (unspecified) bottom of the recess 45 in the collar 55 and forms an obliquely to the axial direction A lying locking or clamping element 70, so that two opposite (also unspecified) edges of the recess 73 with the side surfaces 32nd of the square pin 30 can be brought into engagement.

Between the clamping frame 71 and the bottom 53 of the sleeve 150 sits the spring 80, which permanently loads the clamping frame 71 and thus the blocking element 70 in the axial direction A or in the direction R2. The clear height of the recess 45 in the collar 55 and the height of the support edge 75 relative to the top 77 of the clamping frame 71 are dimensioned so that the clamping frame 71 relative to the square pin 30 can always assume its inclination.

If you introduce the square pin 30 in the joining direction R1 in the device 40 and in the handle 20, the inclined clamping frame 71 is pivoted against the resistance of the spring 80 from its inclined position down. The pivoting movement takes place parallel to the side surfaces 32 of the square pin 30 about the lateral support edge 75 around. The square pin 30 can freely enter into the recess 73 in the clamping frame 71, wherein the edges of the recess 73 on the side surfaces 32 of the square pin 30 slide freely along.

On the other hand, if the square pin 30 is pulled in the opposite direction R2, the clamping frame 71 permanently loaded by the spring 80 remains in its oblique position and the edges of the recess 73 already resting against the side surfaces 32 of the square pin 30 are pressed into the square pin 30. The resulting immediately clamping effect prevents the square pin 30 can be solved from the device 40 and thus from the handle 20. In order to achieve a high clamping force, it is expedient to arrange the support edge 75 at a maximum distance from the longitudinal axis A.

Again, the handle 20 without the use of a tool can be firmly connected to the square pin 30. After insertion of the pin part of the actuating handle 10 from one side of the door leaf in the lock nut only the still missing handle 20 with the device 40 must be plugged onto the free end of the square pin 30. As soon as both handles 20 abut the door plates, the assembly is completed. The result is a permanently reliable connection between driver 30 and handle 20, which also automatically adapts to different frame and wing thicknesses.

Fig. 1 shows the clamping frame 71 in engagement with the square pin 30. This is stored in the square recess 44 of the collar 55 radially and circumferentially and guided radially in the bottom 53 of the sleeve. The clamping frame 71 is floatingly mounted in the (slot) recess 45 so that it can align itself with the square pin 30. This ensures a smooth insertion of the square pin 30 into the device 40 and yet always a form-fitting concern of the clamping edges of the clamping frame 71 on the side surfaces 32 of the square pin 30th

The (shaft) recess 45 is arranged in the collar 55 of the sleeve 150 such that it is completely covered after mounting the device 40 in the handle neck 23. As a result, the clamping frame 71 can not fall out even when the square pin 30 is not inserted.

In order to further simplify the overall structure of the actuating handle 10, in particular the locking device 40, the number of different components in the embodiment according to the invention of Fig. 2 reduced to a total of three, which not only has a favorable effect on the assembly costs, but especially significantly reduces the production costs.

The sleeve 150 has - in contrast to the previous design - no cylinder jacket 52 and no bottom 53, but only a collar 55 which is provided for fixing the device 40 in the handle neck 23, for example with an external thread 51. The latter engages in a corresponding internal thread 29 in the edge region of the handle neck 23. Above the thread 51, the collar 55 is reduced in outside diameter. Below the thread 51 of the stepped collar 48 is formed, with which the sleeve 150 on the step 21 of the recess 25 in the handle neck 23 finds an axial stop.

Below the collar 48 serving as a flange cover sleeve 150 frontally has a plane in itself oblique surface 90, which is inclined relative to a plane E perpendicular to the axial direction A by an angle β. One recognizes in Fig. 3 in that the direction of inclination of the inclined surface 90 extends diagonally to the cross section of the square pin 30, which is rotationally fixedly received in the sleeve 150 by a matching recess 44.

Between the inclined surface 90 of the sleeve 150 and another radially recessed step 92 of the recess 25 of the handle neck 23 are two clamping frame 71 axially superimposed, which enclose the square pin 30 on all sides. Both frames 71 are centrally provided with a respective angular recess 73 (see Fig. 5 ), whose dimensions are so far greater than the outer dimensions of the square pin 30, that both frames 71 can lie obliquely with respect to the plane E. It is important that the recesses 73 are aligned with the recess 44 in the collar 55 so that you can insert the square pin 30 unhindered in the device 40. The inner part 26 of the recess 25 may also be formed quadrangular below a lower step 94 in the handle neck 23 to accommodate the square pin 30 positively.

The stacked, identically formed clamping frame 71 form according to the invention the locking and clamping elements 70 of the locking device 40. They are acted upon in direction R2 by a permanent force which is applied by the coil spring 80. The latter is supported within the handle neck 23 on the lower step 94 and presses the clamping frame 71 against the inclined surface 90th

To assemble the actuating handle 10, the pin part (not shown) of the actuating handle 10 is inserted from one side of the door leaf into the lock nut. Then you put the handle 20 with the locking device 40 on the free end of the square pin 30. This penetrates into the recess 44 of the sleeve 150 until it reaches the slanted clamping frame 71.

If the square pin 30 is inserted further in the joining direction R1 into the device 40 or into the handle 20, then the slanted clamping frames 71 are pivoted downwards out of their oblique position against the resistance of the spring 80. Due to the orientation of the oblique surface 90, the pivoting movement always takes place diagonally to the cross-sectional area of the square pin 30. Consequently, the edges of the recesses 73 initially slide along the square pin 30. This can freely enter into the recesses 73 of the clamping frame 71 and thus in the locking device 40.

If, on the other hand, one pulls the square pin 30 out of the handle 20 in the opposite direction R2, the clamping frames permanently loaded by the spring 80 engage 71 in its diagonal skew to the square pin 30 immediately in the corner edges 33 and in the side surfaces 32 of the square pin 30 a. This is blocked immediately, wherein the clamping over the corner edges 33 of the square pin 30 is significantly more effective than a clamping alone on the side surfaces 32nd

The inclined surface 90 of the sleeve 150 ensures that the clamping frame 71 always form a maximum lever arm. A separate support edge as a rotation axis is not required. On the contrary: the clamping frames 71 can be inexpensively manufactured in the form of simple disks which are to be provided only with a square aperture 73, e.g. by punching. The likewise geometrically simple sleeve 150 is preferably a diecast part, which is also inexpensive to manufacture.

The handle 20 can be fixed without tools with the square pin 30. Once both handles 20 rest against the door plates, creates a permanently reliable connection between the driver 30 and handle 20, which withstands even increased loads permanently and adapts at any time to different frame and wing thicknesses. The locking elements 70 are due to the compression spring 80 permanently and without play on the corner edges 33 and at least partially on the side surfaces 32 of the square pin 30 at. As soon as you want to move it in the direction of R2, engage the permanently active in the power flow elements 30, 150, 70 of the device 40, so that the square pin 30 is locked or fixed almost without any movement. Also dimensional tolerances fall due to the simple design of the device 40 within the handle 20 hardly in the weight, which also has a favorable effect on the production costs.

The friction and clamping effect can be further increased if necessary, if one arranges three or more clamping frame 71 on the square pin 30. As a result, the anchoring in the device 40 withstands even extremely high loads permanently.

In order to disassemble the actuating handle 10, a through bore 96 is radially introduced in the side wall of the handle neck 23, in which a (not shown) piercing tool is inserted, which is provided at the end with a slightly conical tip. The axial position of the bore 96 depends essentially on the number and the thickness of the clamping plates 71 when they enclose the square pin 30. It is chosen such that, when inserting the piercing tool, the clamping disks 71 are moved axially in the direction R1. Reach this one location about parallel to the plane E, you can simply and conveniently pull the square pin 30 from the device 40 and thus pull the handle 20 of the square pin 30.

The 4 and 5 show still another embodiment of an actuating handle according to the invention.

In the same function of the locking device 40, the sleeve 150 is not provided with an external thread 51, but with a circumferential groove 98 which receives a snap ring 99 form-fitting manner. Accordingly, the handle neck 23 no internal thread 29, but a circumferential recess 88, which can also receive the snap ring 99 positively.

As an anti-rotation 55 radially projecting ears or projections 86 are provided on the outer circumference of the collar, which engage in the axial mounting of the sleeve 150 in corresponding recesses 87 in the inner circumference of the handle neck 23. For a solid connection between the sleeve 150 and handle 20 is made, which can transmit both the longitudinal traction and the torque solid positive fit between the two joining partners.

At an in Fig. 6 shown further embodiment of an actuating handle 10, the device 40 is designed for fixing the square pin 30 as a preassembled unit.

The sleeve 150 has a cylinder jacket 52, which is provided at its end located in the handle neck 23 with a bottom 53 and at its end facing the door leaf has a collar 55. The latter is supported by a radially formed collar 49 on the end face of the (not shown here) from the handle neck 23. It is preferably dimensioned so that it forms the neck or the grip collar 24 of the handle 20.

The handle neck 23 facing inner end face of the collar 55 is provided with the inclined surface 90, the inclination direction is diagonal to the cross section of the square pin 30 and a square pin 30 positively receiving recess 44 in the collar 55 runs. The recess 44 rotatably receives the square pin 30 for torque transmission.

The bottom 53 of the sleeve 150 is formed by a sleeve lower part 82, which is inserted from below firmly into the sleeve 150 and into the cylinder jacket 52. The connection can be made for example by welding, gluing or flanging. But you can also screw the lower part 82 in the sleeve 150.

The sleeve lower part 82 forms with the bottom 53 a support surface 83 for the coil spring 80, which permanently loads two clamping frames 71 arranged above it in the direction R2. The clamping frame 71 form the locking elements 70 for the device 40. They rest at least at the edge on the inclined surface 90 and are supported by the sleeve lower part 82, which is provided for this purpose above the bottom 53 with a cylindrical support edge 84. The clear distance between the support edge 84 and the inclined surface 90 is dimensioned so that the clamping frame 71 relative to the square pin 30 can assume their skew.

Below the bottom 53, the sleeve base 82 has a cylindrical extension 85, the inner surfaces 91 form a square recess, which is congruent to the recess 44 in the collar 55 and the square pin 30 receives positively and rotationally fixed. The lower end of the extension 85 forms a bottom surface 95, in the centric to the longitudinal axis A, a counterbore 89 is introduced.

It can be seen that the sleeve 150 and the sleeve lower part 82 form a cartridge which is inserted into the front end of the handle neck 23 of the handle 20. The determination in a handle 20, which is designed as a tubular handle, can be done for example by gluing or welding, while the cartridge 150, 82 is preferably axially screwed in a solid handle 20. For this purpose, a screw (not shown) is inserted into the bore 89 and axially screwed to the handle neck 23 of the handle 20. A pulling force acting on the handle 20 is thereby transmitted directly axially from the screw to the cartridge 150, 82 and thus to the device 40 and the square pin 30 locked therein. The screw is accessed through the recesses 44, 73 and the coil spring 80 before the square pin 30 is inserted. In order to ensure an always reliable torque transmission from the device 40 to the handle 20, the outer circumference of the sleeve 150 and the cylinder jacket 52 is provided with a (not shown) profiling. But you can also use the radial projections 86, which engage in the same shape recesses 87 in the handle neck 23 (see. 4 and 5 ).

Of particular importance is that the device 40 in the formation of Fig. 6 is prefabricated as an encapsulated assembly and screwed only in the handle neck 23 of the handle 20, pressed or glued. This simplifies storage. The device 40 can also be factory provided with any door or window handle. The square recesses 44 and 91 in the cartridge 150, 82 take over the leadership of the square pin 30, which can absorb 150 moments after insertion into the sleeve. The axial adjustment range of the pin connection is thus increased.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. Thus, the actuating handle 10 can also be applied to door fittings having on one side of the door panel instead of a handle a door knob or doorknob. Furthermore, one can also form the actuating handle 10 as a window handle.

In the embodiments of the Fig. 1 to 6 one can use only a single or three or more instead of two clamping plates 71, which are arranged one above the other in the axial direction. It is important that the locking elements 70 all rest without play on the side surfaces 32 or on the longitudinal edges 33 of the square pin 30 so that the blocking effect can occur immediately as soon as a force in the direction R2 is exerted on the square pin 30. Depending on the application, a combination of different blocking elements 70 may be expedient.

The locking elements 70 may also be formed as pawls (not shown), which are pivotally mounted in the sleeve 150 and which engage with end-formed claws or points in the side surfaces 32 or in the edges 33 of the square 30.

The grooves, beads or the like. in the side surfaces 32 of the square pin 30 must - as far as they are provided - not necessarily parallel to the longitudinal axis A. It is also possible to form the grooves 34 transversely in order, for example, to increase the friction or clamping effect or to form latching steps for the insertion of the square pin 30 into the device 40.

It can be seen that the device is mirror-symmetrical ( Fig. 1 to 6 ) is formed to the longitudinal axis A. This not only has a favorable effect on the production costs. Also the Assembly of the actuating handle 10 itself is extremely simple, because all components must be joined only axially.

Furthermore, it can be seen that the device 40 forms an axially continuous, frictional locking. This allows the smooth insertion of the square pin 30 in the direction of R1. In the opposite direction R2, however, the square pin 30 is immediately locked and locked within the device 40.

Another advantage of the extremely simple and quick to assemble actuating handle 10 is that already existing substructures such as rosettes, door plates and the like. can be used immediately. Structural changes or adjustments are not required. At the same time, with the quick assembly for the user imperceptible automatically any existing door thickness or window thickness taken into account when the pair of handles or the door handle 20 is plugged as far as the stop on the shield or the rosette.
