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.

Other solutions use solid profile square pins in conjunction with slotted leaf spring elements or with corrugated spring elements to improve axial strength and to overcome manufacturing tolerances (see, for example, 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 30.

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 engaged, the invention provides that between the handle and the driver element, a device is provided which is formed such that the insertion of the driver element in the handle in a first direction effected and locked in the opposite direction

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.

a further embodiment of a locking device for an actuating handle as a preassembled unit.

The generally designated 10 in Fig. 1 actuating handle is part of a door fitting having two handles 20 on both sides of a door panel (not shown). Each handle 20 has a handle body 22 and a handle neck 23 which is rotatably supported by a lug or gripping collar 24 in a door plate (not shown). The latter are preferably fastened by means (not shown) screws on the door leaf.

Both handles 20 are connected by the door leaf via a driver element 30, preferably a square pin, axially fixed and rotationally fixed to each other. The square pin 30 extends through the lock nut of a front side inserted into the door leaf (also not shown) mortise, wherein the not visible in Fig. 1 Door handle is preferably fixed by means of a factory pre-assembled clamping or grub screw on the square pin 30.

The door handle 20 shown in Fig. 1 is fixed by means of a device 40 to the square pin 30. This is designed as an automatic locking device such that the square pin 30 in a first direction R1, which is preferably parallel to the longitudinal axis A of the square pin 30, without much resistance in the device 40 and thus in the handle neck 23 is inserted until each handle 20 with his handle neck 23 rests on the door plate. If, on the other hand, one wishes to pull the handle 20 away from the square pin 30 in the opposite direction R2, the device 40 locks the square pin 30 directly, i. this can no longer be pulled out of the handle neck 23. The device 40 holds the square pin 30 while so tight, so that both door handles 20 are not only rotationally fixed, but also fixed axially and wobble on the door leaf, without having to use a tool for this purpose.

The device 40 is seated in the embodiment of Fig. 1 frontally in a recess 25 in the handle neck 23. It has a sleeve 50 with a cylinder jacket 52, which at its end lying in the handle neck 23 a bottom 53 and at its outer end a flange-like collar 55th having. The latter is supported on the end face 27 of the handle neck 23 and is preferably dimensioned so that it forms the neck or the grip collar 24 of the handle 20.

The sleeve 50 is firmly anchored in the recess 25, for example, pressed, locked or screwed. But you can also cohesively connect to the handle neck 23, for example by gluing or welding. In the bottom 53 is centered to the longitudinal axis A, a quadrangular recess 54 is introduced for the positive and rotationally fixed receiving the square pin 30 (see Fig. 2). The inner part 26 of the recess 25 in the handle 20 may also be formed square below a step or a shoulder 28 for the positive or rotationally fixed reception of the square pin 30. In this case, care must be taken when mounting the sleeve 50 that the recess 54 in the bottom 53 and the recess 25 in the handle neck 23 are congruent to each other.

Below the upper edge 56 of the collar 55 are formed on the inner circumference 57 of the sleeve 50 obliquely outwardly extending surfaces 58. These lie at an angle α to the longitudinal axis A of the square pin 30 and to its side surfaces 32. They extend to about half of the clear height of the sleeve 50. In the embodiment of Fig. 2, the inclined surfaces 58 are not formed separately in the sleeve 50. They form here rather a continuous conical peripheral surface 59, which simplifies the manufacture of the sleeve 50 and thus the device 40.

Within the sleeve 50 is axially displaceable a guide member 60 is arranged, which has a substantially cylindrical outer periphery 61 and a substantially quadrangular inner periphery 62 (see FIGS. 3 to 5). The diameter of the outer circumference 61 corresponds to the smallest diameter of the inner circumference 57 of the sleeve 50, while the dimensions of the inner circumference 62 correspond to the cross-sectional dimensions of the square pin 30, which can be inserted longitudinally displaceably into the guide element 60 with little movement play.

For fixing or fixing the square pin 30 within the device 40, four movable locking elements 70 are provided between the preferably made of metal sleeve 50 and made of metal or plastic guide member 60, which may have the shape of balls 72, for example. Each ball 72 is seated within a bead 64 of the guide element 60 which runs parallel to the longitudinal axis A and is provided with an opening 65 on each side face of the inner circumference 62 facing the square pin 30. The diameter of the apertures 65 is dimensioned relative to the outer diameter of the balls 72 so that they pass with a part of their outer surface inward, but can not fall into the interior of the guide member 60 into it.

The guide element 60 is aligned within the sleeve 50 such that the inner circumference 62 is congruent to the recess 54 in the bottom 53. At the same time, the beads 64 lie with the apertures 65 with respect to the inclined surfaces 58, 59 of the sleeve 50, so that the balls 72 can rest against it.

Below the guide element 60 is a spring 80 - preferably a coil spring - arranged, which is supported on the bottom 53 of the sleeve 50 and the guide member 60 in the axial direction A and R2 in the direction permanently applied with a spring force. At the same time lying between the inclined surfaces 58, 59 of the sleeve 50 and the side surfaces 32 of the square pin 30 blocking elements 70 and 72 permanently loaded in the axial direction A, wherein the guided in the beads 64 of the guide member 60 and projecting through the apertures 65 balls 72nd be pressed by the inclined surfaces 58, 59 radially inwardly, so that the balls 72 always frictionally abut the side surfaces 32 of the square pin 30.

Because the distance at the upper edge 56 of the collar 55 to the guide member 60 is always sufficiently small, the balls 72 can not pass outward, even if the square pin 30 is not inserted in the guide member 60. The latter is thus always secured axially. It can - as Fig. 3 shows - do not fall out of the sleeve 50. The entire device 40 can thus be manufactured as needed as a preassembled unit, which not only has a favorable effect on warehousing and logistics.

It is also possible to use pins or screws (not shown) for the axial securing of the guide element 60, which are screwed radially into the collar 55 and engage in axial slots or recesses in the guide element 60 (also not shown). The pins or screws serve at the same time as a rotation. Alternatively or additionally, the guide element 60 may also be provided with radial protrusions (not shown) or outer warts, which engage behind corresponding guide recesses in the sleeve 50.

The installation of the actuating handle 10 on the door leaf is extremely simple and is done without any use of tools.

In Fig. 3, the square pin 30 is outside the handle 20 and thus outside of the locking device 40. After the (not shown) pin part of the actuating handle 10 has been preassembled from one side of the door leaf through the lock nut, the handle 20 with the locking device 40 is attached to the free end of the square pin 30. This penetrates - as shown in FIG. 4 - initially as far as in the guide member 60 until it reaches the laterally arranged balls 70.

If you push the square pin 30 in the direction of R1 further into the device 40, the balls 72 are first displaced inward and outward, which is possible insofar as the balls 70 dodge due to the obliquely outwardly and inwardly widening surfaces 58, 59 can. The guide member 60 is thereby pushed over the lying in the apertures 65 balls 72 against the spring force of the compression spring 80 also inwardly until the balls 72 lie on the side surfaces 32 of the square pin 30 (see Fig. 5).

The lying on both sides of the door handle 20 are now pushed together until the handle necks 23 abut the respective door plate and engage the mutual gripping collars 26 in the (not shown) bearing openings of the door plates. It does not matter which dimensions the door leaf has or by what means the door plates are attached to the door leaf. It is important only that the locking elements 70 detect the square pin 30, i. that in this case the balls 72 rest on the side surfaces 32.

Attempting to pull apart the door handles 20 in the opposite direction R2 after installation, try the balls 72 on the inclined surfaces 58, 59 and the side surfaces 32 of the square pin 30 unroll, but this does not succeed because they are directly between the wedge-shaped surfaces 32 and 58, 59 are trapped. The resulting frictional engagement prevents the square pin 30 from being released from the device 40 and thus from the handle 20. This is rather firmly locked to the square pin 30, without the need for a tool would have been necessary. If the square pin 30 penetrates into the recess 54 in the bottom 53 of the sleeve 50, then the handle 20 is not only axially fixed via the device 40 but also also connected in a rotationally fixed manner to the square pin 30.

It can be seen that the entire assembly of the actuating handle is limited to the axial joining of the pin part and the handle 20. Neither screws must be tightened nor other fasteners operated or joined. The handling is therefore very simple and extremely stable, because the locking elements 70 are due to the compression spring 80 permanently and without play on the inclined surfaces 58, 59 of the sleeve 50 and the side surfaces 32 of the square pin 30 at. As soon as you want to move it in the direction of R2, the active permanently in the power flow active elements 30, 50, 70 of the device 40, so that the square pin 30 is locked or fixed almost without any movement play.

In the joining direction R1, however, the square pin 30 can be moved at any time until the handles 20 rest against the door plates. Thus, the device 40 already allows during assembly automatically adjusting the pin connection to the respective thickness of the door leaf. The handles 20 are always wobble on the door signs.

In order to further increase the friction and clamping action between the locking balls 72 and the square pin 30, one can parallel in the side surfaces 32 of the square pin 30 to the longitudinal axis A beads or longitudinal grooves 34 which are formed semicircular in cross section. The diameter of each longitudinal groove 34 corresponds to the outer diameter of the balls 72, so that these not only punctiform, but bear with a line contact on the square 30. As a result, the anchoring in the device 40 withstands even greater loads permanently.

In the embodiment of Fig. 6, the inclined surfaces 58 of the sleeve 50 are formed as flat surfaces, because the locking elements 70 inserted in the radial openings 65 of the guide member 60 are formed as rollers or rolling elements 74. The width of the surfaces 58 corresponds substantially to the dimensions of the rollers or rolling elements 74, so that they are always precisely guided. The side surfaces 32 of the square pin 30 are suitably flat. If necessary, longitudinal grooves 34 can also be provided in the side surfaces 32, which are adapted to the contour of the rollers 74.

7 to 9 show the joining process between the square pin 30 and the handle 20 and the sleeve 50 inserted therein. The square pin 30 dips into the guide element 60 of the device 40 and displaces the rollers 74 inwardly and radially outwardly, wherein at the same time here formed without side beads 64 guide member 60 is pushed back. As soon as the rollers 74 rest on the side surfaces 32 of the square pin 30 (FIG. 9), the guide element 60 is not further displaced. However, the square 30 can continue to be pushed in the direction of R1 in the device 40 until the handles 20 strike the door signs.

Pulling in the reverse direction R2 on the handle 20 or on the square pin 30, the rollers 74 are immediately clamped between the wedge-shaped surfaces 58, 59 and 32, i. the relative movement between the driver element 30 and the handle 20 is blocked immediately. The insertion of the driver 30 in the handle 20 in the direction R1, however, is at any time effected. The force relationships when joining the handle 20 and the square 30 in the direction of R1 and pulling the door handle 20 in the reverse direction R2 are thus significantly different, while the geometric conditions always remain unchanged.

For a possibly necessary disassembly of the actuating handle 10, a (not shown) mechanism may be provided which moves the guide member 60 axially in the direction of R1. As a result, the blocking elements 70 are given freedom of movement. You can dodge radially outward within the openings 65 and the square pin 30 can be pulled out of the device 40 without much resistance. In order to enable the attack on the guide member 60, this can always be a bit far out of the sleeve 50.

Instead of balls 72 or rollers 74, the construction according to the invention of FIG. 10 uses square wedge or clamping bodies 76, which are guided in matching radial openings 65 in the guide element 60. Again, it is apparent how the various forces are transmitted within the device 40, the latter being designed such that the insertion of the driver element 30 in the handle 20 in a first direction R1 is always effected, while a relative movement between the driver element 30 and the Handle 20 in the opposite direction R2 is always locked.

A torque acting on the handle 20 is transmitted via the square opening 54 in the sleeve 50 to the square pin 30. The inner part 26 of the recess 25 in the handle neck 23 may support this power transmission, if it is also square and the square pin 30 receives a positive fit.

A force acting on the square pin 30 longitudinal pressure in the direction of R1 causes this can be introduced against the force applied by the spring 80 counterforce in the device 40, wherein the guide member 60 and the locking elements 70 can escape inwardly and radially. The locking elements 70 - here the wedge body 76 - slide along the side surfaces 32 of the square pin 30 along. The sleeve 50 is supported with its collar 55 on the end face 27 of the handle neck 23.

A force acting on the square pin 30 longitudinal tensile force in the direction R2, however, causes the locking elements 70, 76 immediately between the side surfaces 32 of the square pin 30 and the wedge-shaped inclined surfaces 58, 59 of the sleeve 50 are clamped. Pulling the square pin 30 from the device 40 is therefore not possible.

Transverse forces that arise in the handle actuation within the openings 65 in the guide member 60 and in the plane of the locking body 70 each form pairs of forces whose vectors always have opposite signs.

A further embodiment (FIGS. 11 and 12) corresponds in structure and function to the previous exemplary embodiments only with the difference that the device 40 is integrated in the handle 20. The sleeve 50 of the device 40 is integral with the handle neck 23, wherein the directly on the end face 27 of the handle neck 23 attaching collar 55 forms the approach or grip collar 24 with which the handle 20 can be rotatably mounted in a shield or a rosette , The recess 54 for the square pin 30 is formed directly in the handle neck 23 and angular, so that an introduced via the handle 20 torque is transmitted directly to the lock nut and the second handle.

In yet another embodiment of an actuating handle 10 shown in FIG. 13, the device 40 for fixing the square pin 30 is formed as a preassembled unit. The sleeve 50 is provided on its cylinder jacket 52 with an external thread 51 and firmly screwed into a gegengleiches internal thread 29 in the handle neck 23. The over the previous embodiments axially higher trained collar 55 continues to form the lug 24 for the handle 20. However, it is no longer supported externally on the end face 27 of the handle neck 23, but with a collar 48 at an upper stage 21 in the handle neck 23rd At its upper end, the collar 55 is formed lid-like and provided for the torque transmission to the square pin 30 with a same shape recess 44. At the same time the collar 55 forms an axial stop 43 for the guide element 60. This is - as described above - axially slid within the sleeve 50 and loaded by the compression spring 80. The latter is supported on the bottom 53, which is pressed or glued as a separate component from below into the sleeve 50. The bottom 53 may further be provided with a square recess 54 which is congruent with the recess 44. However, it is also possible to form the bottom 53 as a simple ring element, which secures only the guide element 60 and the spring 80.

As FIG. 13 further shows, the blocking elements 70 may be formed as pairs of balls 78, two balls being inserted in each radial opening 65 of the guiding element 60. This has the advantage that the frictional effect on the side surfaces 32 of the square pin 30 and on the below the stop 43 in the sleeve 50 applying inclined surfaces 58, 59 is sufficiently high even without longitudinal grooves 34. On the other hand, it is possible to form the square pin 30 in two parts, wherein the division would be approximately centrally to the balls of two opposing pairs of balls 78. It is also conceivable a combination of the locking elements 70, for example, by two pairs of balls 78 and two individual balls 72nd can be used, wherein for the individual balls 72 further adapted longitudinal grooves 34 can be introduced into the halves of the square pin 30.

Of particular importance is that the device 40 is prefabricated in the embodiment of Fig. 13 as an encapsulated assembly and only has to be screwed into the handle neck 23 of the handle 20, pressed or glued. This not only simplifies warehousing. The device 40 can - depending on the customer - factory provided with any door or window handle. The square recesses 44 and 54 in the sleeve 50 take over the leadership of the square pin 30, which can absorb 50 moments after insertion into the sleeve. The axial adjustment range of the pin connection is thus increased.

Fig. 14 shows a further simplified embodiment of an actuating handle 10 according to the invention with a device 40 which is designed such that the insertion of the driver element 30 in the (not shown here) handle 20 in a first direction R1 is effected, while the withdrawal of the driver element 30 is locked out of the handle 20 in the opposite direction R2 immediately.

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 therefore supported on one side on the (unspecified) underside 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 32 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.

Another important advantage of the embodiment of Fig. 14 is that the number of components is significantly reduced. Instead of 4 or more locking elements 70 in the form of balls 72, rollers 74, wedge bodies 76 or the like., Which are arranged in a separate guide member 60, one needs only a pivotally mounted clamping frame 71 within the sleeve 150, the square pin 30th encloses. By lying parallel to the side surfaces 32 of the square pin 30 edges of the recess 73 in the frame 71, a high clamping force is achieved, so that the actuating handle 10 withstands even increased loads permanently.

Fig. 14 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 50 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 simplify the overall structure of the actuating handle 10, in particular the locking device 40 even further, the number of different components in the embodiment of Fig. 15 is reduced to a total of three, which not only has a favorable effect on the assembly costs, but especially the production costs significantly decreases.

The sleeve 150 has - in contrast to the previous designs - 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. It can be seen in Fig. 16 that the inclination direction of the inclined surface 90 extends diagonally to the cross section of the square pin 30, which is rotatably received by a same shape recess 44 in the sleeve 150.

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. 18), the dimensions of which are 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 further 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. The pivoting movement is always due to the orientation of the inclined surface 90 Thus, 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, the square pin 30 is pulled out of the handle 20 in the opposite direction R2, the clamping frames 71 permanently loaded by the spring 80 immediately engage the corner edges 33 and the side surfaces 32 of the square pin 30 in their diagonal oblique position relative to the square pin 30. 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 connected without tools firmly 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. Reaching this one position approximately parallel to the plane E, you can easily and conveniently pull the square pin 30 of the device 40 and thus deduct the handle 20 of the square pin 30.

FIGS. 17 and 18 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.

This arrangement allows the axial locking of the sleeve 150 in the handle neck 23. As an anti-rotation on the outer circumference of the collar 55 radially projecting ears or projections 86 are provided which engage in the axial mounting of the sleeve 50 in corresponding recesses 87 in the inner circumference of the handle neck 23. For a firm connection between the sleeve 50 and handle 20 is made, which can transmit both the longitudinal tensile force and the torque solid positive fit between the two joining partners.

In a further embodiment of an actuating handle 10 shown in FIG. 19, the device 40 for fixing the square pin 30 is designed as a preassembled structural 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 27 of the (not shown here) from the handle neck 23. He is preferably dimensioned so that it forms the approach 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 lower part 82 has a cylindrical extension 85, the inner surfaces 91 form a square recess 54 which is congruent with 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. An attacking force on the handle 20 is characterized directly axially by the screw on the cartridge 150, 82 and thus on the Device 40 and locked therein square spindle 30 transmitted. 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. However, it is also possible to use the radial projections 86, which engage in identically shaped recesses 87 in the handle neck 23 (see FIGS. 17 and 18).

Of particular importance is that the device 40 is prefabricated in the embodiment of FIG. 19 as an encapsulated assembly and only in the handle neck 23 of the handle 20 has to be screwed, 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 FIGS. 1 to 13, instead of four blocking elements 70, only two or even more than four can be used. In the exemplary embodiments of FIGS. 14 to 19, instead of two clamping disks 71, it is also possible to use only a single or even three or more, 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 (not shown) pawls which are pivotally mounted in the sleeve 50 and formed with the end Claws or tips engage in the side surfaces 32 or in the edges 33 of the square 30.

The grooves 34, 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 designed to be either rotationally symmetrical (FIGS. 1 to 13) or mirror-symmetrical (FIGS. 14 to 19) to the longitudinal axis A. This not only has a favorable effect on the production costs. The assembly of the actuating handle 10 itself is extremely simple because all components must be joined only axially.

The square pin 30 is circumferentially surrounded by locking or clamping bodies 70 after insertion into the device 40, which lie approximately at the same height. The blocking bodies 70 can be arranged in a radial opening 65 of an axially guided guide element 60 in the sleeve 50. Suitably, a blocking body 70 is provided for each side surface 32 of the square pin 30, i. the latter are arranged circumferentially at angular intervals of 90 °. The blocking bodies 70 are enveloped by the conical bore 59 or the individually formed inclined surfaces 58. The circular cylindrical shell 52 has a collar 55, with which the sleeve 50 rests on the end face 27 of the handle neck 23. A square recess 54 in the bottom 53 of the sleeve 50 receives the square pin 30 for torque transmission form-fitting manner.

On the bottom 53 of the sleeve 50 rests a compression spring 80 which urges the guide member 60 permanently axially. As a result, the locking bodies 70 are permanently pressed between the conical bore 59 and the side surfaces 32 of the square pin 30. If now pulled on the square pin 30 in the direction R2, the locking body 70 want to roll on the conical bore 59 and the inclined surfaces 58, but this is not possible because the surfaces 32, 58 and 59 are not parallel to each other. The locking bodies 70 are clamped between the sleeve 50 and the square pin 30.

It can be seen that the device 40 forms an axially stepless, frictional locking. This allows the smooth insertion of the square pin 30 in the direction R1. In the opposite direction R2, however, the square pin 30 is immediately locked and locked within the device 40. The angle α between the inclined surfaces 58, 59 and the side surfaces 32 of the square pin 30 is dimensioned so that a sufficient clamping force is generated and that the guide element 60 can not slide out of the sleeve 50 in the absence of square pin 30.

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.

All of the claims, the description and the drawings resulting features and advantages, including design details, spatial arrangements and method steps may be essential to the invention both in itself and in various combinations.
