Description

The invention relates to an operating handle according to the preamble of claim 1.

Operating handles for components such as doors, windows and the like are known in a wide variety of designs. 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 handle, which is provided via a rod-shaped actuating element, preferably a polygonal or square actuating pin, for rotating an actuating or locking device in the wing of a door or window. In the case of doors, a handle or handle is usually provided at both ends of the operating polygon, preferably detachably connected to it.

In a variety of applications, it is necessary that, in addition to the usual rotational forces for opening or closing the closing mechanism of a door or window fitting, additional axial tensile forces must also be transmitted via the rod-shaped actuating element or the polygonal actuating element. This is particularly the case with door fittings. For this purpose, an axially stationary and rotationally fixed element is provided between the handle 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 is variably adjustable in order to adapt to different strengths of the To ensure the door leaf or window sash.

Numerous fastening and assembly solutions are already known from the prior art, in which the operating 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 operating polygon, which is designed in such a way that the insertion of the operating polygon in a front recess of the handle along the actuation axis in one direction is possible, but is blocked in the opposite direction.

In the US 708 336 A For example, such an axial locking function is realized by means of a clamping frame element which encloses the polygonal actuation received in the handle neck and is pivotably mounted on it. The clamping frame element can thus be brought into engagement with the actuating polygon in a non-positive, positive and/or frictional manner, with the clamping frame element itself being subjected to a spring force in a direction parallel to the actuation axis or axis of rotation of the handle having a rotary knob via a spring element. The spring element is 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 spring force generated against a contact surface which runs obliquely to the actuation axis or longitudinal axis of the actuation polygon, thereby achieving a stationary axial locking of the handle on the actuation polygon. The handle neck is designed as a component that is separate from the rotary knob, on whose free end facing away from the door leaf the rotary knob is releasably 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 US 2,478,304 A an operating mechanism with a similar clamping mechanism can be found. 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 operating handle with at least one handle and with an operating polygon is known, in which the operating polygon can be brought into engagement with the handle in a rotationally fixed manner, a clamping device being provided between the handle and the operating polygon, which is designed such that the operating polygon fits into the handle in one can be inserted in the first direction and pulled out in the opposite direction is blocked. The clamping device comprises a sleeve fixed in the handle with a sleeve interior in which several clamping frame elements and a spring element are accommodated. The actuating polygon can be brought into engagement with the clamping frame elements accommodated in the sleeve in a non-positive, positive and/or frictional manner, with 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 pivotally 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. Due to the stepped design of the handle recess, the spiral spring element accommodated therein is supported on an annular contact surface caused by the stepped design of the recess che, 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 through the inner surfaces of the handle recess adjoining the free end of the spring element.

Based on the prior art shown, the invention is based on the object of providing an actuating handle with a clamping device which, compared to the prior art, has a simple and inexpensive structure and, in particular, high torsional and axial strength.

The task is based on an operating handle with the features of the preamble of claim 1 solved by its characterizing features.

The essential aspect of the actuation handle according to the invention is that the clamping body of the clamping device is received in the recess in a form-fitting and non-rotatable manner. The actuating handle according to the invention, in particular the clamping device accommodated therein, therefore has a simple and cost-effective structure and high torsional and axial strength. The clamping device particularly advantageously forms a quick-connection device.

In a preferred embodiment variant, the clamping frame element is accommodated in the recess in a form-fitting, rotationally fixed manner and can be pivoted about the actuation axis. The clamping frame element is therefore particularly advantageously guided directly through the recess or the correspondingly shaped inner surface or inner wall of the recess.

Furthermore, it is advantageous for the clamping body to be designed in the shape of a socket and/or for a further frontal contact surface of the clamping body to be designed flush with the free end of the neck section. Advantageously, the socket-shaped clamping body can therefore be quickly and easily secured in a rotationally fixed and axially fixed manner in the recess of the handle, in such a way that the free end face of the neck section of the handle forms a flush end face with the end face.

Furthermore, the clamping body is advantageously made in one piece from a solid material made of metal, in particular steel, stainless steel, aluminum, brass or zinc or a corresponding alloy comprising at least one of the materials mentioned. This makes cost-effective production and individual design of the clamping body possible without any problems in order to create a positive connection with the neck section of the handle. Particularly preferably, a clamping body produced in this way is designed to produce a rotationally fixed and axially fixed connection with the actuating polygon.

In an advantageous embodiment variant of the invention, the clamping body, which is received in the recess in a form-fitting and rotationally fixed manner, is connected to the neck section of the handle at the end face, preferably screwed, glued, welded or pinned. This ensures a simple and reliable connection between the clamping body and the handle, which can also be detached depending on the connection technology, which can be achieved, for example, by several connecting means, in particular screwing means, which are screwed along the actuation axis into the gap-shaped transition area existing between the clamping body and the neck section. This can be done either directly or using a pre-drill. Screw means or screw elements formed by grub screws are particularly suitable.

Further advantageously, the at least one clamping frame element can be disc-shaped or plate-shaped, this particularly preferably having a circular cross section with at least one lateral recess. Only a slight pivoting of the clamping frame elements leads to a direct non-positive, positive and/or frictional connection between at least one edge surface of the actuating polygon and at least one breakthrough edge of the clamping frame element that rests on it. In addition, additional lateral guidance of the clamping frame element is provided by the neck section of the handle.

Particularly advantageously, the clamping device has several clamping frame elements that are directly adjacent to one another, whereby 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 adapted to the cross section and dimensions of the actuating polygon. 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 aligned particularly advantageously elements with the passage opening of the clamping body and the spring 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 relative to the square pin in such a way that each edge surface of the square pin can be brought into operative connection with one opening edge when the clamping frame element is pivoted about the actuation axis.

In a particularly preferred embodiment variant, the recess has a cross-sectional contour that deviates from the circular shape, the cross-sectional contour of the recess and the cross-sectional shape of the clamping body being adapted to one another in order to produce a positive connection. Particularly advantageously, a positive connection of the tongue-and-groove type can be produced quickly and easily.

Furthermore, it is advantageous for the cross-sectional shape of the at least one clamping frame element to at least partially match the cross-sectional shape of the clamping body. This ensures additional rotation-proof, lateral guidance of the clamping frame elements over the inner surfaces of the recess.

The spring element is particularly preferably formed by a spiral spring element. This enables the required spring force to be reliably provided and the actuation polygon to be carried out through the freely accessible spring interior.

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 operating polygon by means of the clamping frame elements can be released using a pointed tool or pin-like element. The operating handle or handle can be quickly and easily removed from the door or window fitting without special tools.

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 numbers that are necessary 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 how it works. In particular, the representations in the figures only serve to explain the basic principle of the invention.

In 1 is shown as an example in a perspective view of an operating handle 1 according to the invention for components such as doors, windows and the like, which has at least one handle or 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. This shows 1 For example, the neck section 2.1 and the transition area between the neck section 2.1 and the actuating section 2.2 in a detail view, which does not completely show the free end of the actuating section 2.2, but only indicates its course.

The actuating handle 1 according to the invention is preferably intended for use in a door fitting or window fitting and can be connected to it in a rotationally fixed manner for mounting on the door or window fitting by plugging it onto the actuating polygon 3, namely via a clamp connection. In a preferred embodiment riante, the operating handle 1 can be detachably connected to the operating polygon 3, so that it can be removed again from the operating polygon 3 after assembly.

In the present exemplary embodiment, the actuating polygon 3 is designed as a square pin, which in the 1 is only shown in part. It goes without saying that alternative embodiment variants of such a driver element are also possible without departing from the idea of the invention.

The handle or handle 2 of the operating handle 1 has at least one recess 2.3 extending along the operating axis BA, which is arranged in the free end of the neck section 2.1 facing away from the operating section 2.2. The longitudinal axes of the neck section 2.1 and the actuation section 2.2 run, for example, at a right angle to one another, with the longitudinal axis of the neck section 2.1 preferably coinciding with the actuation axis BA of the actuation handle 1.

After mounting the actuation handle 1 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. Here, the actuating polygon 3 forms a driver element 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 is preferably made of a solid material, for example metal or a metal alloy, in particular zinc or a zinc alloy, into which the recess 2.3 has already been made during production. The handle 2 is preferably produced by means of a die-casting process, in particular a zinc die-casting process, in which the liquid melt of the solid material made of metal or the metal alloy is pressed into a die-casting mold, in particular a steel casting mold, in particular under high pressure and high speed. The die-casting mold can already be designed to form the frontal recess 2.3 in the neck section 2.1. Alternatively, the recess 2.3 can also be machined into the solid material of the neck section 2.1 on the front side.

In 2 is an example of a perspective view of an operating handle 1 according to the invention without an operating polygon 3, in which the handle 2 is shown partially cut away in the area of the neck section 2.1. The 2 thus shows a section through the neck section 2.1 along a sectional plane II, which accommodates the actuation axis BA. In the 2 The recess 2.3 shown preferably extends almost completely over the neck section 2.1 along the actuation axis BA and runs concentrically to the actuation axis BA. The recess 2.3 can be formed, for example, by a blind hole-like bore with a cylindrical basic shape, which has a largely closed end section 2.3 ', the cross section of which is adapted to positively receive the free end of the actuating polygon 3. The end section 2.3' is preferably located in the transition area between the neck section 2.1 and the pusher section 2.2. In the embodiment variant shown in the figure, the cross section of the recess 2.3 is reduced in steps to the end section 2.3 ', which forms a positive reception of the free end of the actuating polygon 3 in the end section 2.3'. The diameter of the recess 2.3 thus jumps back in steps in the direction of the longitudinal axis LA or actuation axis BA and the cross section of the end section 2.3 'takes on the cross-sectional shape of the actuation polygon 3. In the embodiment variant shown, the end section 2.3' of the recess 2.3 is adjoined by a through hole, which enables access from the section of the handle 2 opposite the free end of the neck section 2.1 into the recess 2.3. For example, starting from the end section 2.3' along the actuation axis BA, the through hole has a funnel-shaped bore section followed by a cylindrical bore section.

According to the invention, a multi-part clamping device 4 is accommodated in the recess 2.3 of the handle 2 for producing a rotationally fixed and preferably also axially fixed connection, preferably a clamping connection between the handle 2 and the actuating polygon 3. The 3 and 4 show, for example, perspective views of the multi-part clamping device 4 from different directions. By means of the multi-part clamping device 4, the handle 2 is not only rotationally fixed, but preferably also axially stationary on the polygonal actuation 3, in relation to the actuation axis BA. The clamping device 4 thus forms a quick-connection device, by means of which a preferably releasable clamping connection of the handle 2 with the actuating polygon 3 can be produced. For this purpose, the clamping body 4.1 rests directly on the inner surface of the neck section 2.1 of the handle 2 which forms the recess 2.3.

According to the invention, the multi-part clamping device 4 has at least one clamping body 4.1 with a through opening 4.1a for carrying out the actuating polygon 3, at least one clamping frame element 4.2, 4.2 'and one adjoining it along the actuating axis BA Spring element 4.3. The clamping body 4.1 extends along a longitudinal axis LA and has a first frontal contact surface 4.1', which runs in a plane oriented perpendicular to the longitudinal axis LA or actuation axis BA, and an opposite second frontal contact surface 4.1", which has an oblique contact surface for the at least a clamping frame element 4.2, 4.2' forms. In the assembled state, the second frontal contact surface 4.1" separates a closed receiving space from the recess 2.3, which is designed to receive and guide the at least one clamping frame element 4.2, 4.2' and the spring element 4.3 adjoining it. The second frontal contact surface 4.1" extends in a plane oriented obliquely to the longitudinal axis LA or actuation axis BA and thus forms an acute angle w with the actuation axis BA.

According to the invention, the clamping body 4.1 is received in a form-fitting and rotationally fixed manner in the recess 2.3 of the neck section 2.1 of the handle 2 and thus completely closes the free end of the recess 2.3 opposite the end section 2.3 'or the free-end opening of the recess 2.3. For this purpose, the clamping body 4.1 has a substantially cylindrical basic shape, with the opposite first and second end faces 4.1 ', 4.1" each forming essentially annular, flat surface sections which enclose the through opening 4.1a concentrically and in a ring shape. The clamping body 4.1 can, for example, be designed in the shape of a socket be.

The clamping body 4.1 is preferably made of a solid material, preferably metal, in particular steel, stainless steel, aluminum, brass or a corresponding alloy. To produce the clamping body 4.1, an extrusion process or a casting process, in particular die-casting process, can be used. In a preferred embodiment variant, the clamping body 4.1 is manufactured as an extruded aluminum profile, an extruded brass profile or as a zinc die-cast component.

Particularly preferably, the first frontal contact surface 4.1' of the clamping body 4.1, which is received in a form-fitting manner in the recess 2.3, is flush with the free, frontal end of the neck section 2.1. In an alternative embodiment variant, the first frontal contact surface 4.1' of the clamping body 4.1 can also spring back slightly from the free end of the neck section 2.1 into the recess 2.3.

The clamping body 4.1 is connected to the neck section 2.1 of the handle 2 on the front side, in particular screwed, glued, welded or pinned. In the present exemplary embodiment, the clamping body 4.1 is screwed to the neck section 2.1 of the handle 2, namely after the clamping body 4.1 has been inserted into the recess 2.3. The clamping body 4.1 is screwed to the handle 2 by driving in screw elements 5, preferably grub screws, at the front. For this purpose, after inserting the clamping body 4.1 into the recess 2.3, pre-drillings are preferably made in the transition area between the recess 2.3 and the outside of the clamping body 4.1 for easier and guided insertion of the grub screws. As a result, the clamping body 4.1 is additionally mounted in the handle 2 in a fixed position. In the 1 to 4 Examples of corresponding screw elements 5 for screwing the clamping body 4.1 into the recess 2.3 of the neck section 2.1 of the handle 2 are shown. For example, four grub screws 5 can be used.

Furthermore, the recess 2.3 has a cross-sectional contour that deviates from the circular shape, which enables the clamping body 4.1 to be mounted in a positive and rotationally fixed manner with respect to the actuation axis BA. The cross-sectional contour is understood to mean the plane extending through a section through the clamping body 4.1 along a plane perpendicular to the longitudinal axis of the clamping body 4.1 or the actuation axis BA.

According to the invention, due to the cross-sectional contour of the clamping body 4.1, which deviates from the circular shape, it is not only accommodated in a form-fitting and rotationally fixed manner in the recess 2.3, but the recess 2.3 also forms a guide section for the at least one clamping frame element 4.2, 4.2 ', which is connected to the clamping body 4.1 at least one clamping frame element 4.2, 4.2' accommodated on the actuating polygon 3 leads laterally.

The cross-sectional shape of the clamping body 4.1 is preferably adapted to the cross-sectional contour of the recess 2.3, in such a way that when the clamping body 4.1 is inserted into the recess 2.3 of the neck section 2.1, a positive connection is created, which creates a rotationally fixed connection about the actuation axis BA between the clamping body 4.1 and the Neck section 2.1 of the handle 2 causes. The through opening 4.1a of the clamping body 4.1 is adapted to the actuation polygon 3 in terms of its cross section and dimensions and is aligned along the actuation axis BA with the end section 2.3 'of the recess 2.3. 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, with the square pin comprising four edge surfaces of the same width. Accordingly, that is Cross section of the end section 2.3 'of the recess 2.3 as well as the cross section of the through opening 4.1a are also square and designed to positively accommodate the square pin.

When inserting the clamping body 4.1 into the recess 2.3 of the neck section 2.1, a tongue and groove connection is preferably produced. For this purpose, the clamping body 4.1 has at least one spring section 4.1b, which projects radially outwards or projects radially outwards from the lateral surface of the clamping body 4.1 and extends along the longitudinal axis of the clamping body 4 or the actuation axis BA, preferably over the entire length of the clamping body 4.1. To positively accommodate the projection-like spring section 4.1b, the recess 2.3 has a groove section 2.3a, which is adapted to the spring section 4.1b in terms of shape and/or length. In the present exemplary embodiment, four spring sections 4.1b and associated four groove sections 2.3a are provided, which are preferably arranged concentrically around the actuation axis BA. These are, for example, arranged evenly distributed along the circumference, each offset by 90° to one another. This means that two tongue sections 4.1b and two groove sections 2.3a lie opposite each other. It goes without saying that an alternative design and mirrored arrangement of the tongue sections 4.1b or groove section 2.3a on the clamping body 4.1 or in the recess 2.3 is also possible, through which the desired tongue and groove connection is produced without thereby departing from the idea of the invention becomes.

Following the clamping body 4.1 along the actuation axis BA, at least one clamping frame element 4.2, 4.2', preferably several clamping frame elements 4.2, 4.2', is accommodated in the recess 2.3, each of which has a central feed-through opening or a central opening 4.21, 4.21', through which in the mounted State of the actuating polygon 3 is guided and is enclosed by it. This is followed by the spring element 4.3 in the recess 2.3. The spring element 4.3 of the clamping device 1 is intended to generate a spring force F in the recess 2.3, which causes a pretension of the clamping frame elements 4.2, 4.2 'against the second frontal contact surface 4.1". For this purpose, the at least one clamping frame element 4.2, 4.2' is brought into contact with the front contact surface 4.1" of the clamping body 4.1, which runs obliquely to the longitudinal axis LA or actuation axis BA. Due to the resulting inclination of the at least one clamping frame element 4.2, 4.2', a non-positive, positive and/or frictional operative connection can be established between the actuating polygon 3 and the clamping body 3.

The first frontal contact surface 4.1' facing away from the handle 2 forms a flat or flat, annular contact surface and extends in a plane perpendicular to the longitudinal axis of the clamping body 4.1 or perpendicular to the actuation axis BA. The second frontal contact surface 4.1" of the clamping body 4.1 facing the handle 2 forms a flat or flat, annular contact surface which runs slightly obliquely relative to the first frontal side 4.1' and forms an angle w between 10° and 25° with the first frontal side 4.1' . The second end face 4.1" thus extends in a second plane which runs perpendicular to the actuation axis BA. The second level encloses the angle w between 10° and 25°, preferably between 15° and 20°, with the first level of the first end face 4.1'.

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

The clamping frame element 4.2, 4.2' is preferably designed in the shape of a disk or plate and has a central opening 4.21 and at least one, preferably several, lateral recesses 4.22, 4.22'. In the present exemplary embodiment, the clamping frame element 4.2, 4.2' has approximately the same cross-sectional shape of the clamping body 4.1, so that additional lateral guidance is provided by the wall of the neck section 2.1 of the handle 2 forming the recess 2.3.

This also provides a positive connection between the clamping frame element 4.2, 4.2' and the recess 2.3 for guiding it along the actuation axis BA.

The spring element 4.3 is received in the recess 2.3 between a contact surface surrounding the end section 2.3 'and the at least one clamping frame element 4.2, 4.2' and is thereby also guided laterally in the recess 2.3 along the actuation axis BA. In the present exemplary embodiment, the spring element 4.3 is realized in the form of a spiral spring element. The spring element 4.3 is set up to generate a spring force F.

The clamping frame elements 4.2, 4.2 'connect directly to the second frontal contact surface 4.1" of the clamping body 4.1 along the actuation axis BA and are pressed against the second frontal contact surface 4.1" which runs obliquely to the actuation axis BA under the action of the spring force F generated by the spring element 4.3 . Due to the resulting oblique position of the clamping frame elements 4.2, 4.2 'with respect to the actuation axis BA, the opening edges of the clamping frame elements 4.2, 4.2' surrounding the opening 4.21 are brought into operative connection with the edge surfaces of the operating polygon 3 designed as a square pin, so that a force, shape and / or frictional operative connection between at least two, preferably all edge surfaces of the actuating polygon 3 designed as a square pin and the respectively assigned breakthrough edge of the clamping frame element 4.2, 4.2 'is created.

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

The central opening 4.21 is adapted in terms of its cross-sectional shape and dimensions to the cross-sectional shape and dimensions of the operating polygon 3 in order to ensure that the operating polygon 3 passes loosely 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, 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 be pivoted about the actuation axis BA. For example, the edge lengths of the square opening 4.21 are at least 2% larger than the edge widths of the square pin. In the present exemplary embodiment, the edge lengths of the breakthrough edges of the breakthrough 4.21 are, for example, 8.2 mm to 9.2 mm.

The actuating polygon 3 can thus be guided through the through opening 4.1a of the clamping body 4.1, the central opening 4.21, 4.21' in the respective clamping frame element 4.2, 4.2' and the adjoining spring element 4.3 into the end section 2.3'. When the actuating polygon 3 is inserted through the central opening 4.21, 4.21' in the respective clamping frame element 4.2, 4.2', the spring element 4.3 causes it to be pivotably mounted, in such a way that the section of the respective clamping frame element which is further away from the end section 2.3' of the recess 2.3 4.2, 4.2' is pivoted in such a way that the angle w included with the actuation axis is reduced and the non-positive, positive and/or frictional connection is thereby dissolved, or at least reduced in such a way that the actuation polygon 3 can be passed through in the direction of the end section 2.3 ' is released. However, pulling out the actuating polygon 3 from the central opening 4.21, 4.21' is blocked due to the pivoting back of the clamping frame element 4.2, 4.2' and the oblique contact position on the second end face 4.1" of the clamping body 4.1.

The clamping device 4 according to the invention thus forms a releasable quick connector, by means of which a rotationally and axially fixed connection between the handle 2 and the operating polygon 3 can be produced. For this purpose, the operating polygon 3 can be inserted in the direction of the handle 2 into the recess 2.3 and the clamping device 4 accommodated therein in the manner described, but after the free end of the operating polygon 3 has been passed through the complete clamping device 4 into the end section 2.3 'of the recess 2.3, a Blocking the movement of the operating 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. The actuating polygon 3 is then fixed in the handle 2 in a rotationally fixed and axially stationary manner.

The clamping frame element 4.2, 4.2', which is under pretension and arranged obliquely to the actuation axis BA, thus enables pivoting against the spring force F generated by the spring element 4.3 when the actuating polygon 3 formed by a square pin is inserted through the square openings 4.21. The spring force F generated by the spring element 4.3 presses the clamping frame elements 4.2, 4.2 ', which are guided laterally over the inside of the recess 2.3 and held in a predetermined position when the actuating polygon 3 is pulled out, against the second frontal contact surface 4.1" of the clamping body 4.1, which runs obliquely to the actuating axis BA, so that an inclination of the Clamping frame elements 4.2, 4.2 'is effected reason for which 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 breakthrough edge of the breakthrough 4.21 of the clamping frame elements 4.2, 4.2 ', which rests on an edge surface. Like from the 3 becomes clear, the clamping frame elements 4.2, 4.2' are shifted parallel to one another, that is, a stepped edge profile and thus free edges are created.

Via an access opening 2.5 provided in the neck section 2.1 in this area, which, for example, in 2 is shown, the clamping frame element(s) 4.2, 4.2' can easily be moved against the spring force F 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 relaxed and the blocking of movement of the actuating polygon 3 is released by means of the clamping frame elements 4.2, 4.2 '. The handle 2 can be removed from the operating polygon 3. Loosening the clamping device 4 is therefore particularly advantageous 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 relaxing the jammed, slightly overlapping clamping frame elements 4.2, 4.2 '. For this purpose, the tip of the tool or pin-like element simply needs to be placed on the edge of a clamping frame element 4.2, 4.2 ', which is freely accessible from the outside via the access opening 2.5.

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