Description

The invention relates to an actuating handle according to the preamble of patent claim 1 and an associated clamping device according to patent claim 17 for use in an actuating handle.

Operating handles for components such as doors, windows and the like are known in a wide variety of design variants. These are part of a door or window fitting and are used in particular to open and close doors, windows or similar components. For this purpose, they usually have a handle, preferably a handgrip, which is provided via a rod-shaped actuating element, preferably an actuating polygon or square pin, for rotary entrainment of an actuating or closing device in the leaf of a door or window. In the case of doors, a handle or handle is usually provided at both ends of the actuating polygon, preferably releasably connected to it.

In a large number of applications, it is necessary for additional axial tensile forces to be transmitted via the rod-shaped actuating element or the actuating polygon, in addition to the usual rotary forces for opening or closing the closing mechanism of a door or window fitting. This is particularly the case with door fittings. For this purpose, an axially stationary and non-rotatable connection is provided between the grip or handle and the rod-shaped actuating element or the actuating polygon, preferably at its free end, in such a way that the location of the axial connection can be variably adjusted in order to adapt to different strengths of the door leaf or window sash.

Numerous fastening and assembly solutions are already known from the prior art, in which the actuating polygon can be connected in a rotationally fixed manner to at least one handle or handle: A clamping device is provided between the handle and the actuating polygon, which is designed in such a way that the insertion of the actuating polygon in a frontal recess of the handle along the actuation axis in one direction is possible, but blocked in the opposite direction.

In the US 708 336 A For example, such an axial blocking function is realized by means of a clamping frame element which encloses the actuating polygon accommodated in the handle neck and is pivotably mounted thereon. The clamping frame element can thus be brought into positive, positive and/or frictional engagement with the actuating polygon, with the clamping frame element itself being acted upon in a direction parallel to the actuating axis or axis of rotation of the handle having a rotary knob via a spring element with a spring force. The spring element is in this case formed by a spiral spring which is accommodated in a recess in the handle neck of the handle. For this purpose, the clamping frame element is pressed against the axial locking direction via the generated spring force against a contact surface running obliquely to the actuating axis or longitudinal axis of the actuating polygon, thereby achieving a stationary axial locking of the handle on the actuating polygon. The handle neck is designed as a separate component from the rotary knob, on whose free end facing away from the door leaf the rotary knob is detachably mounted, in particular screwed on. The spiral spring is accommodated in a recess provided in the handle neck, through which the actuating polygon is guided in the assembled state to produce the clamping connection with the clamping frame element.

Also from the U.S. 2,478,304 A is an actuator with a similar clamping mechanism. Here the clamping frame element and the associated spring element are accommodated either in a housing part of the handle that forms the handle neck or in the interior of the rotary knob.

Furthermore, from the EP 1 683 933 B1 an actuating handle with at least one handle and with an actuating polygon, in which the actuating polygon can be brought into engagement with the handle in a rotationally fixed manner, with a clamping device being provided between the handle and the actuating polygon, which is designed in such a way that the actuating polygon can be inserted into the handle in a can be inserted in the first direction and is blocked from being pulled out in the opposite direction. The clamping device comprises a sleeve which is fixed in the handle and has a sleeve interior which accommodates a plurality of clamping frame elements and a spring element. The actuating polygon can be positively, positively and/or frictionally engaged with the clamping frame elements accommodated in the sleeve, the clamping frame elements being permanently acted upon in the opposite direction by the spring force generated by the spring element. For this purpose, the clamping frame elements are pivotably accommodated in the sleeve. In an alternative embodiment variant, the handle has a stepped recess in the neck area, which extends along the actuation axis of the actuation polygon, which can be closed via a closure element. The spiral spring accommodated in it is supported by the stepped design of the handle recess element on an annular contact surface caused by the stepped formation of the recess, so that after the recess has been closed by means of the closure element, the clamping frame elements also accommodated in the recess are subjected to a spring force. The lateral guidance of the clamping frame elements takes place here through the inner surfaces of the grip recess adjoining the free end of the spring element.

Proceeding from the prior art shown, the invention is based on the object of specifying an actuating handle with a clamping device which, compared to the prior art, has a simple and cost-effective design and high axial strength.

Starting from an actuating handle with the features of the preamble of patent claim 1, the task is solved by its characterizing features. The invention also relates to a clamping device for use in an actuating handle according to the features of claim 17.

The essential aspect of the actuating handle according to the invention can be seen in the fact that the clamping device has a spring and holding element connected to the clamping body, with the at least one clamping frame element being received between the clamping body and the holding and spring element by means of the spring and holding element and being pivotable on the actuating polygon stored and can be acted upon by a spring force. Particularly advantageously, the clamping frame elements are not only guided laterally by means of the spring and holding element, but are simultaneously also subjected to a spring force, in such a way that the clamping frame elements can pivot about the actuating axis against the spring force. The clamping frame elements are set at an angle to the actuating axis by means of the spring and holding element and are permanently acted upon by the spring force provided when the actuating polygon is carried out by the clamping device. As a result, the actuating polygon can be inserted quickly and easily into the clamping device in a first direction along the actuating axis, but this effectively blocks the actuating polygon from being pulled out in the opposite, second direction along the actuating axis. Due to the spring and holding force provided by the holding and spring element, the clamping frame elements are set at an angle to the actuating axis or longitudinal axis of the actuating polygon and thus a non-positive, positive and/or frictional operative connection between at least one edge surface of the actuating polygon and at least one adjacent edge surface Breakthrough edge of a clamping frame element made. The actuating handle according to the invention, in particular the clamping device accommodated therein, thus has a simple and cost-effective design and high axial strength. The clamping device thus forms a quick connection device.

Furthermore, the clamping body is advantageously designed in the form of a bush. Advantageously, the actuating polygon can be passed through the through-opening and the clamping body can be quickly and easily mounted in a rotationally fixed manner and fixed axially in the recess of the handle. The clamping body is preferably accommodated in a form-fitting manner in the recess of the.

In a preferred embodiment of the invention, the spring and holding element is detachably connected to the clamping body, or the clamping body and the spring and holding element are formed in one piece or in one piece. As a result, the clamping force of the clamping device can be adjusted by introducing further clamping frame elements between the clamping body and the spring and holding element. The one-piece or one-piece design of the clamping body with the spring and holding element allows a further saving of separate components and thus a simple and quick assembly of the clamping device in the neck section of the handle.

The at least one clamping frame element can also advantageously be designed in the form of a disk or plate, with this particularly preferably having a circular cross section. Only slight pivoting of the clamping frame elements leads to a direct non-positive, positive and/or frictional operative connection between at least one edge surface of the actuating polygon and at least one break-through edge of the clamping frame element lying against it. In addition, an additional lateral guidance of the clamping frame element through the neck section of the handle is thereby possible.

In a particularly advantageous manner, the clamping device has a plurality of clamping frame elements directly adjacent to one another, as a result of which the locking force and thus the axial strength of the clamping device can be increased. The clamping device is particularly advantageously designed to produce a rotationally fixed and axially fixed connection with the actuating polygon.

In a further embodiment variant, the at least one clamping frame element has a preferably central opening, the cross section and dimensions of which are more similar to the cross section and dimensions of the actuation edge adjusted. The dimensions of the opening are advantageously larger than the dimensions of the actuating polygon in order to ensure pivoting of the clamping frame element about the actuating axis. The openings in the clamping frame elements are particularly advantageously aligned with the passage opening of the clamping body and a passage in the spring and holding element.

In a preferred embodiment variant, the actuating polygon is formed by a square pin with a square cross section. The axial arrangement of the openings of the clamping frame elements, in particular their opening edges, is preferably carried out in such a way relative to the square pin that each edge surface of the square pin can be brought into operative connection with a respective opening edge when the clamping frame element is pivoted about the actuating axis.

Furthermore advantageously, the spring and holding element has an elongate holding web section and a spring section, which are connected to one another via a curved connecting section. This results in an axially fixed connection of the spring and retaining element to the clamping body while at the same time introducing a spring force into the clamping frame elements, at least one of which rests flat on the spring section.

The clamping frame element is also advantageously held by the spring and holding element in such a way that it runs at an angle to the actuating axis. For this purpose, the spring section runs obliquely to the longitudinal axis of the elongate holding web section. The end face of the clamping body facing the clamping frame elements is preferably designed as an inclined surface, which particularly preferably runs parallel to the spring section.

In a preferred embodiment variant, the spring section is pivotably connected to the elongate retaining bar section about a pivot axis, the pivot axis running approximately perpendicular to the longitudinal axis of the elongate retaining bar section, which extends parallel to the actuation axis. This ensures that the spring force provided is applied to the clamping frame elements uniformly and over a wide area.

In an advantageous development of the invention, the spring section has a breakthrough opening which is adapted to the actuating polygon in terms of cross-sectional shape and dimensions. The dimensions of the breakthrough openings are preferably selected to be larger than the dimensions of the breakthroughs in the clamping frame elements in order to enable the spring section to pivot as freely as possible despite the axial mounting on the clamping body.

In one embodiment of the invention, an adapter sleeve can be provided for adapting the clamping device to different handle diameters, in which the clamping body is accommodated. Advantageously, the clamping device according to the invention can be used in actuating handles with different handle diameters.

In a preferred embodiment variant, an access opening is arranged in the neck section of the handle in the area of the clamping frame elements, via which the blocking of a movement of the actuating polygon can be released by means of the clamping frame elements using a pointed tool or pin-like element. The actuating handle or the handle can thus be removed quickly and easily from the door or window fitting without special tools.

The invention also relates to a clamping device for use in an actuating handle, comprising at least one clamping body with a through-opening for the passage of the actuating polygon and at least one clamping frame element adjoining it along the actuating axis, with the clamping frame element enclosing the actuating polygon and forming a force-, shape- and / or frictional active connection can be brought. Particularly advantageously, the clamping device has a spring and holding element connected to the clamping body, with the at least one clamping frame element being received between the clamping body and the holding and spring element by means of the spring and holding element and being pivotably mounted on the actuating polygon and permanently subjected to a spring force. The clamping device can be designed as a spare or replacement part, so that if it is damaged, the entire actuating handle does not have to be replaced, but only the clamping device has to be replaced.

Further developments, advantages and possible applications of the invention also result from the following description of exemplary embodiments and from the figures. All of the features described and/or illustrated are fundamentally the subject matter of the invention, either alone or in any combination, regardless of how they are summarized in the claims or how they relate back to them.

Identical reference numbers are used in the figures for elements of the invention that are the same or have the same effect. Furthermore, for the sake of clarity, only reference symbols that are required for the description of the respective figure are shown in the individual figures. The invention is also shown in the figures only as a schematic view to explain the mode of operation. In particular, the representations in the figures only serve to explain the basic principle of the invention.

In 1 is shown by way of example in a perspective view of an actuating handle 1 according to the invention for components such as doors, windows and the like. The actuating handle 1 according to the invention is preferably intended for use in a door fitting or window fitting.

The operating handle 1 has at least one handle 2 with a neck section 2.1 and an operating section 2.2 and an operating polygon 3 extending along an operating axis BA. In the present embodiment, the actuating polygon 3 is designed as a square pin. It goes without saying that alternative design variants of such a driver element are also possible without departing from the spirit of the invention.

The grip or handle 2 of the actuating handle 1 has at least one recess 2.3 which extends along the actuating axis BA and is arranged in the free end of the neck portion 2.1 which faces away from the actuating portion 2.2. The longitudinal axes of the neck section 2.1 and the actuating section 2.2 preferably run at right angles to one another, with the longitudinal axis of the neck section 2.1 preferably coinciding with the actuating axis BA of the actuating handle 1.

After the actuation handle 1 has been installed on the door or window fitting, it can be pivoted about the actuation axis BA or the axis of rotation of the door or window fitting. In this case, the actuating polygon 3 forms a driver which can be brought into operative connection with an actuating mechanism of the respective door fitting or window fitting in a manner known per se.

The handle 2 itself can be made, for example, from a solid material, in which the recess 2.3 is introduced by manufacturing. However, the handle 2 is preferably made of a hollow material, so that at least the cavity of the handle 2 enclosed by the neck section 2.1 already forms the recess 2.3.

In 2 a perspective view of an actuating handle 1 according to the invention without actuating polygon 3 is shown as an example, in which the handle 2 is shown partially cut open in the area of the neck section 2.1. In the recess 2.3 of the handle 2, a clamping device 4 for producing a non-rotatable, preferably detachable connection between the handle 2 and the actuating polygon 3 is accommodated. By means of the clamping device 4, the handle 2 can also be fixed axially in place on the actuating polygon 3. The clamping device 4 thus forms a quick connection device.

The clamping device 4 is preferably itself arranged in a form-fitting and non-rotatable manner in the recess 2.3 of the neck section 2.1 of the handle 2. For example, the clamping device 4 is pinned to the neck section 2.1 of the handle 2, i.e. after the insertion of the clamping device 4 into the recess 2.3, by driving a pin element from the outside of the handle 2 into the clamping device 4, it is positioned and/or rotationally fixed in the handle assembled. 1 and 2 show an embodiment variant of the actuating handle with a clamping device 4 pinned in the neck section 2.1.

According to the invention, the clamping device 4 has at least one clamping body 4.1 with a through-opening 4.1a for the passage of the actuating polygon 3, at least one clamping frame element 4.2, 4.2' adjoining it along the actuating axis BA and a spring and holding element 4.3.

The at least one clamping frame element 4.2, 4.2' encloses the actuating polygon 3 and can be brought into a non-positive, positive and/or frictional operative connection with it. For the passage of the actuating polygon 3, the at least one clamping frame element 4.2, 4.2' has a central passage opening or an opening 4.21.

The spring and holding element 4.3 of the clamping device 1 is connected to the clamping body 4.1, preferably detachably, with the at least one clamping frame element 4.2, 4.2' being received between the clamping body 4.1 and the holding and spring element 4.3 by means of the spring and holding element 4.3 pivotally mounted on the actuating polygon 3 and can be acted upon by a spring force F. The spring force F is here provided by the holding and spring element 4.3.

In 3 is an example of a perspective view of recorded on the actuating polygon 3 clamping device 4 shown without handle 2 to explain its structure and operation. the 4 until 6 show the clamping device 4 without actuating polygon 3 from different perspectives.

The clamping body 4.1 is preferably designed in the form of a socket and is intended for positive reception in the recess 2.3. It has a cylindrical basic shape, with the opposite first and second end faces 4.1', 4.1'' each forming annular surface sections which surround the through-opening 4.1a.

The passage opening 4.1a is provided for the passage of the actuating polygon 3 and is adapted to the actuating polygon 3 in terms of its cross section and its dimensions. In the present exemplary embodiment, when the actuating polygon 3 is designed as a square pin, the through-opening 4.1a has a square cross-section, i.e. the square pin comprises four edge surfaces of equal width.

The clamping body 4.1 is preferably made from a solid material, for example metal, plastic, aluminum, brass or a comparable solid material. An extrusion process or a casting process, in particular a die-casting process, can be used to produce the clamping body 4.1. In a preferred embodiment variant, the clamping body 4.1 is produced as an aluminum extruded profile, brass extruded profile or as a die-cast zinc component.

The first end face 4.1' facing away from the handle 2 forms a planar or flat surface and extends in a first plane E1 running perpendicularly to the longitudinal axis of the clamping body 4.1 or perpendicularly to the actuation axis BA. In the mounted state, the first end face 4.1' of the clamping body 4.1 facing away from the handle 2 is approximately flush with the free end of the neck section 2.1 of the handle 2 or jumps back slightly from the free end of the neck section 2.1 into the recess 2.3.

The second end face 4.1" of the clamping body 4.1 facing the handle 2 forms a planar or flat sloping surface, which runs slightly obliquely compared to the first end face 4.1' and encloses an angle w between 10° and 25° with the first end face 4.1'. The second The end face 4.1″ thus extends in a second plane E2, which encloses an angle w between 10° and 25°, preferably between 15° and 20°, with the first plane E1 of the first end face 4.1′.

In the exemplary embodiments shown in the figures, a first and second clamping frame element 4.2, 4.2′ is provided, which are identical to one another and directly adjoin one another along the actuation axis BA, preferably at least partially lying flat against one another. It goes without saying that more than two clamping frame elements 4.2, 4.2' can also be provided without departing from the idea of the invention.

The clamping frame elements 4.2, 4.2' directly adjoin the second end face 4.1" of the clamping body 4.1 along the actuation axis BA and are acted upon by the force generated by the holding and spring element 4.3 Spring force F is pressed against the second end face 4.1", which runs obliquely to the actuation axis BA. Due to the resulting inclined position of the clamping frame elements 4.2, 4.2' relative to the actuation axis BA, the opening edges of the clamping frame elements 4.2, 4.2' surrounding the opening 4.21 are operatively connected to the edge surfaces of the actuating polygon 3 designed as a square pin, so that a non-positive, positive and/or frictional operative connection is created between at least two, preferably all, edge surfaces of the actuating polygon 3 designed as a square pin and the respective associated breakthrough edge of the clamping frame element 4.2, 4.2'.

In 8th a perspective view of an isolated clamping frame element 4.2, 4.2' is shown as an example. The clamping frame element 4.2, 4.2' is preferably designed in the form of a disc or plate and has an opening 4.21 and a recess 4.22. In the present exemplary embodiment, the clamping frame element 4.2, 4.2' has a circular cross section, so that an additional lateral guidance is given by the wall of the neck section 2.1 of the handle 2 forming the recess 2.3.

The clamping frame element 4.2, 4.2' is preferably made of metal, for example stainless steel, and can have a surface that is hardened at least in sections. The clamping frame element 4.2, 4.2' is preferably produced by a stamping process, so that sharp-edged breakthrough edges are formed, which increase the clamping effect of the clamping device 4, in particular the frictional forces generated. The clamping frame elements 4.2, 4.2', which are designed in the form of discs or plates, have a thickness of between 1 mm and 3 mm, preferably 2 mm, for example.

The opening 4.21 is adapted in terms of its cross-sectional shape and dimensions to the cross-sectional shape and the dimensions of the actuating polygon 3 in order to ensure loose passage of the actuating polygon 3 through the opening 4.21. In the present exemplary embodiment, the actuating polygon 3 is formed by a square pin which has a square cross section.

The square pin preferably has four edge surfaces, each with an edge width of 8 mm to 9 mm. The opening 4.21 also has a square cross section, which is enclosed by four opening edges of equal length, with the edge length of the opening edges of the clamping frame elements 4.2, 4.2' exceeding the edge width of the edge surfaces of the square pin in order to enable it to pivot about the actuation axis BA. For example, the edge lengths of the square opening 4.21 are at least 2% greater than the edge widths of the square pin. In the present exemplary embodiment, the edge lengths of the opening edges of opening 4.21 are, for example, 8.2 mm to 9.2 mm.

This in 8th The clamping frame element 4.2, 4.2' exemplified thus has an opening 4.21, which is formed by four opening edges of equal length, with two adjacent opening edges enclosing a 90° angle and two opposite opening edges running parallel to one another.

The clamping frame element 4.2, 4.2' is preferably formed symmetrically to an axis of symmetry SS, namely mirror-symmetrically. The axis of symmetry SS runs through the opposite corners of the square opening 4.21 and divides the recess 4.22 into two approximately identical recess halves.

7 shows an example of a perspective view of a released spring and holding element 4.3, which has an elongate holding web section 4.31, to which a spring section 4.33 is connected via a curved connecting section 4.32. The spring section 4.33 is resiliently connected via the curved connecting section 4.32 to the elongate holding web section 4.31, ie the spring section 4.33 is pivotably connected about a pivot axis SA to the elongate holding web section 4.31. The pivot axis SA runs perpendicular to the longitudinal axis LA of the elongated holding web section 4.31, which extends parallel to the actuation axis BA.

The elongated holding web section 4.31 extends parallel to the actuation axis BA and is accommodated in a corresponding elongated, preferably groove-shaped holding recess 4.1b on the outside of the clamping body 4.1. The spring section 4.33 is disc-shaped or plate-shaped and, analogous to the clamping frame elements 4.2, 4.2', has a breakthrough opening 4.34, which is adapted to the polygonal actuator 3 in terms of cross-sectional shape and dimensions.

In the present exemplary embodiment, the opening 4.34 has a square cross-section, the opening 4.34 being formed by four opening edges of equal length, the edge length of which exceeds the edge width of the actuating polygon 3 designed as a square pin. So that the square pin 3 can easily through the clamping device 4, in particular the clamping body 4.1, the following two clamping frame elements 4.2, 4.2' as well as through the spring section 4.33.

The spring section 4.33 is also mirror-symmetrical to an axis of symmetry SS, which runs through the two opposite corners of the square opening 4.34 and intersects the longitudinal axis LA of the elongated holding web section 4.31 and the pivot axis SA at an intersection. The axis of symmetry SS preferably runs perpendicular to the pivot axis SA. Furthermore, the spring section 4.33 extends in a third plane E3, which runs parallel to the second plane E2 and thus to the inclined surface or second end face 4.1" of the clamping body 4.1. The longitudinal axis LA and the axis of symmetry SS thus span a plane of symmetry that covers the entire clamping device 4 into two approximately identical halves, in particular also the actuating polygon 3 accommodated therein.

The spring and holding element 4.3 is made of metal, preferably stainless steel or spring steel. The thickness of the spring section 4.33 is smaller than the thickness of the clamping frame elements 4.2, 4.2'. Spring section 4.33 is preferably adapted to the configuration of clamping frame elements 4.2, 4.2' in terms of cross-sectional shape and the shape of breakthrough opening 4.34. The breakthrough openings 4.34 are selected to be larger than the breakthroughs 4.21 in the clamping frame elements 4.2, 4.2'.

The clamping device 4 according to the invention forms a detachable quick connector, by means of which a rotationally and axially fixed connection between the handle 2 and the actuating polygon 3 can be produced. For this purpose, the actuating polygon 3 can be pushed in the direction of the handle 2 into the recess 2.3 and the clamping device 4 accommodated therein, but after the free end of the actuating polygon 3 has been passed through the complete clamping device 4, in particular the breakthrough opening 4.34 of the spring section 4.33 of the spring and holding element 4.3 the movement of the actuating polygon 3 in the opposite direction, i.e. in the direction of the door fitting or window fitting and thus away from the handle 2, is blocked. The actuating polygon 3 is then fixed in the handle 2 in a rotationally fixed and axially fixed manner.

The spring section 4.33 of the spring and holding element 4.3 thus enables the actuating polygon 3 formed by a square pin to be pivoted about the pivot axis SA or the actuating axis BA against the spring and retaining element 4.3. The spring force F generated by the spring and retaining element 4.3 presses the clamping frame elements 4.2, 4.2', which are guided laterally over the inner sides of the recess 2.3 and are held in a predetermined position when the actuating polygon 3 is pulled out, against the diagonal to the second end face 4.1" of the clamping body 4.1 running along the actuating axis BA, so that the clamping frame elements 4.2, 4.2' are inclined, as a result of which there is a non-positive, positive and/or frictional operative connection between at least two, preferably all, edge surfaces of the actuating element designed as a square pin hrkants 3 and the breakthrough edge of the breakthrough 4.21 of the clamping frame elements 4.2, 4.2', which rests against an edge surface.

How from the 5 becomes clear, the clamping frame elements 4.2, 4.2' move relative to one another when the square pin 3 is pushed in, ie a stepped edge profile and thus free edges result. A provided in the neck section 2.1 in this area access opening 2.5, which example in the 2 and 10 is shown, the spring section 4.33 of the spring and holding element 4.3 can then easily be bent in the direction of the handle 2, ie away from the clamping device 4, with the aid of a pointed tool or pin-like element which is passed through the access opening 2.5. The clamping device 4 is thereby relieved and the blocking of a movement of the actuating polygon 3 by means of the clamping frame elements 4.2, 4.2' is released. The handle 2 can be pulled off the actuating polygon 3. The clamping device 4 can be released particularly advantageously by inserting a pin-like element through the access opening 2.5 in the area of the neck section 2.1 into the recess 2.3 and releasing the clamped, slightly overlapping clamping frame elements 4.2, 4.2'. For this purpose, the tip of the tool or pin-like element only has to be applied to the edge of a clamping frame element 4.2, 4.2' that is freely accessible from the outside via the access opening 2.5.

The spring and holding element 4.3 has a spring and holding function and is either detachably or firmly connected to the clamping body 4.1, in such a way that the spring and holding element 4.3 is connected to the clamping body 4-1 in an axially stationary manner. The connection can be made, for example, by gluing or welding to the clamp body 4.1, with the elongated holding web section 4.31 being received in the groove-shaped holding recess 4.1b on the outside of the clamp body 4.1 and glued or welded therein. As an alternative to this, the elongated holding web section 4.31 can be pinned or screwed to the clamping body 4.1.

In one embodiment variant, a positive and/or non-positive and/or frictional connection can be provided between the elongated holding web section 4.31 and the elongated holding web section 4.31 accommodated in the groove-shaped holding recess 4.1b of the clamping body 4.1. In the 9 and 10 an embodiment variant is shown, for example, in which a form-fitting connection is provided. Here, the elongate holding web section 4.31 has two holding lug sections 4.31a, 4.31b running perpendicularly to the longitudinal axis LA, which are accommodated in corresponding lateral recesses of the groove-shaped holding recess 4.1b.

To produce the spring and holding element 4.3, a one-piece flat component is produced in a first processing step from a sheet-like material, in particular stainless steel or spring steel, in which the elongated holding web section 4.3 and the spring section 4.33 run in one plane. Subsequently, in a further processing step, the one-piece, flat component is bent around the pivot axis SA and thus the bent connecting section 4.32 and the one spring section 4.33 are produced.

In a further embodiment according to 11 the clamping body 4.1 is accommodated in an adapter sleeve 5 in order to be able to use identical clamping devices 4 in actuating handles 1 with different handle diameters. The adapter sleeve 5 was used to adapt to a larger handle diameter. The adapter sleeve 5 preferably has two opposing guide nose sections 5a, 5b, which protrude from the outer edge of the adapter sleeve 5 in the actuation direction BA and are provided for lateral guidance of the clamping frame elements 4.2, 4.2' received between them. To adapt the clamping device 4 to different handle diameters, differently dimensioned adapter sleeves 5 can be provided. However, the clamping frame elements 4.2, 4.2' are still freely accessible and are not accommodated or housed by the adapter sleeve 5 in the manner of a housing. Rather, the adapter sleeve 5, with the exception of the guide nose sections 5a, 5b, extends exclusively in the area of the clamping body 4.1.

The invention has been described above using exemplary embodiments. It goes without saying that numerous changes and modifications are possible without departing from the inventive idea on which the invention is based.
