Description

The invention relates to an actuating handle for wing-like components such as windows, doors and the like according to the preamble of claim 1.

Actuation handles are used, for example, for opening and closing a window or a door and comprise a handling part in the form of, for example, a door handle, which is non-rotatably connected to a driver element, for example in the form of a square pin. By turning the door handle with this rotatably connected square pin is also rotated and operated, for example, a door lock.

The driver usually has to be transferred via the handling part introduced axial tensile and compressive forces on the wing-like component, since, for example, after opening a door lock by means of the actuating handle, the door is raised. The connection between the handling part and the driver element must be designed so that both are connected to each other both axially and non-rotatably after assembly. In conventional actuation handles known from the prior art, a grub screw, for example, is screwed through a corresponding gripping section of the handling part and brought into contact with the entrainment element. A disadvantage of these known from the prior art actuating handle, however, is the complex installation, since the handling part must first be pushed onto the driver element, whereupon subsequently by means of a tool, such as a screwdriver or Allen key a screw is rotated through the through hole of the handling part, until it is in contact with the driver element.

From the EP 1 683 933 B1 a generic actuating handle is known which comprises a handle and a driver member which is rotatably engageable with the handle engaged, wherein between the handle and the driver element, a clamping device is provided which is designed such that the insertion of the driver element in the handle in a first direction is effected and is locked in an opposite direction. In this case, the clamping device according to one embodiment comprises two in the axial direction of the driver successively arranged, pivotable clamping frame, which are each formed closed, enclose the driver element and can be brought into clamping engagement with the driver element. The clamping frames are arranged in a sleeve which is fixed in the handle. Furthermore, the clamping frames are pressed by a spring permanently in the direction of an inclined surface, which is provided on the end face of a sleeve which surrounds the driver element. The pivot axis of the clamping frame is arranged diagonally to a cross-sectional area of the driver element, so that the clamping frame are only in engagement with the corner edges of the driver element.

The invention has for its object to provide an actuating handle for wing-like components such as windows, doors and the like, which allows a particularly simple and fast assembly and disassembly and reliably prevents unintentional removal of the handling part of the driver element.

This object is achieved by an actuating handle with the features of claim 1. Advantageous embodiments are described in the subclaims.

The actuating handle according to the invention comprises a handling part, a driver element and a receiving sleeve which is rotatably connected to the handling part or connected and having a receiving opening through which the driver element is inserted into the receiving sleeve in an insertion direction, wherein the driver element with the receiving sleeve is rotatably connected. Furthermore, the actuating handle comprises a clamping device, by means of which the driver element in the receiving sleeve is clamped such that withdrawal of the driver element is prevented against the insertion, and comprising a first clamping frame and a second clamping frame, each having a recess for passing the driver element and have a engageable with the driver element in contact clamping surface. The first clamping frame and the second clamping frame are arranged opposite each other such that the two recesses together form a passage opening for the driver element. Furthermore, the two clamping frames are pivotable in opposite pivot directions. By inserting the driver element in the passage opening the two clamping frames are pivotable from a starting position in which they form a first angle with each other in a position in which they include a second angle which is smaller than the first angle, wherein the clamping frame by means of Kraftausübeeinrichtung are subjected to force in the direction of its initial position and exert a holding force due to the contact of the clamping surfaces with the driver element on the driver.

In the actuating handle according to the invention, the first clamping frame is thus pivoted about a first pivot axis and the second clamping frame about a second pivot axis during insertion of the driver element in the receiving sleeve, wherein the distance between the clamping side and the clamping surface of the first clamping frame and the clamping side or clamping surface of the second clamping frame enlarged. The Kraftausübeeinrichtung always exerts on the clamping device one of the insertion direction oppositely directed force, so that the clamping device is subjected to force in the direction of the starting position. By a force exerted on the handling part and the insertion direction opposite tensile force exert the first and the second clamping frame due to the contact of their clamping sides with the driver element on the driver from a holding force, which counteracts a removal of the handling part or the receiving sleeve from the driver.

In the actuating handle according to the invention only the side surfaces of the driver element are subjected to force by the clamping device, so that the edges of the driver element are not damaged. The driver element can simply be pushed into the receiving sleeve in the insertion direction, whereby the two clamping frames pivot away from each other, whereas a removal of the associated with the receiving sleeve operating member is reliably prevented by the driver element. Thus, the actuating handle according to the invention can be used comfortably with different thickness wing-like components, in particular doors.

Preferably, the first clamping frame are pivotable about a first pivot axis and the second clamping frame about a second pivot axis, wherein the pivot axes are oriented perpendicular to the insertion direction and arranged parallel to each other.

Each clamping frame preferably comprises a clamping projection which is connected to the clamping side of the clamping frame and protrudes beyond the clamping side and which is set angularly in the pivoting direction of the clamping frame.

As a result, an insertion of the driver element is facilitated by the passage opening of the clamping device, since the clamping projections of the clamping frame a kind of insertion funnel form for the driver element. Furthermore, the clamping projections can dig in a force exerted on the handling part tensile force in the side surfaces of the driver, so that unintentional removal of the handling part is further effectively prevented by the driver element.

Each clamping frame preferably has a projection opposite the clamping side, and the receiving sleeve has at least two radial recesses. The two clamping frames are articulated in the receiving sleeve, by the projections of the clamping frame are received in the respective radial recesses.

In an appropriately trained actuating handle, the articulated receiving the clamping frame in the receiving sleeve is particularly easy.

Preferably, the Kraftausübeeinrichtung is designed as a spring force device, which is arranged in the receiving sleeve and is supported on this.

In a further preferred embodiment of the actuating handle, the handling part has a recess into which the receiving sleeve is insertable and rotatably connected to the handling part such that when inserted into the recess driver element, the receiving sleeve between the handling part and the driver element is positioned.

The receiving sleeve can be arranged integrally in the handling part, so that the handling part can be pre-assembled together with the receiving sleeve, whereby a Installation of the actuating handle on site is particularly easy.

In the description that follows, the same reference numerals designate the same components or the same features that in order to avoid a repetitive description, a description made with regard to a figure with respect to a component also applies to the other figures.

From the FIGS. 1 and 2 the structure of an actuating handle 1 according to the invention can be seen, in Figure 1, the actuating handle 1 is shown in the disassembled state, whereas in FIG. 2 the actuating handle is shown partially assembled. The actuating handle 1 comprises a handling part 10, which in the illustrated embodiment is designed as a door handle 10 with a neck portion 11 and a grip portion 12. The neck portion 11 is hollow and has a recess 11 'for receiving a fastening sleeve 50 and a receiving sleeve 30.

The receiving sleeve 30 has a receiving opening 31 for receiving a driver element 20. The driver element 20 is formed in the illustrated embodiment as a square pin 20, and the receiving opening 31 of the receiving sleeve 30 has a corresponding cross-sectional geometry, so that the square pin 20 with the receiving sleeve 30 rotatably connected.

The receiving sleeve 30 further comprises a clamping device with two mutually pivotable, identically formed clamping frames 33a and 33b, which are U-shaped or C-shaped and arranged symmetrically with respect to a central plane. The mutually and to this center plane adjacent ends of the two clamping frame 33 a, 33b are separated from each other and can be pivoted mutually. The clamping frames 33a, 33b each have a recess 34a, 34b, so that the opposing clamping frames 33a, 33b together have a passage opening 38 for the square pin 20.

Furthermore, the actuating handle 1 comprises a compression spring 40 designed as Kraftausübeeinrichtung 40 and connectable to the receiving sleeve 30 support ring 41, on which the spring 40 can be supported. In the assembled state, the first and second clamping frames 33a, 33b are always subjected to a force by the spring 40. The force exerted on the clamping frames 33a, 33b spring force is opposite to an insertion direction R, wherein the insertion direction R is the direction in which the square pin 20 is inserted into the receiving sleeve 30. The spring 40 exerts a spring force on the clamping frames 33a, 33b, so that the clamping device is subjected to a force in the direction of a starting position.

The fastening sleeve 50 is inserted into the recess 11 'of the neck portion 11 and there connected to the actuating handle 10, for example by gluing or by welding. The mounting sleeve 50 has recesses 52, which serve for guiding and beyond as a stop for radial projections 32 of the receiving sleeve 30. By the recesses 52, the axial position of the receiving sleeve 30 is fixed in the neck portion 11 and beyond a positive rotation assurance provided, which prevents the receiving sleeve 30 rotates in the mounting sleeve 50. Furthermore, the receiving sleeve 30 in the mounting sleeve 50 glued or welded and thus fixed axially and rotationally fixed.

In the neck portion 11, a later to be explained release tool opening 13 is provided, and in the receiving sleeve 30 is also a release tool opening 13 'is provided. In the assembled state, both release tool openings 13, 13 'are in alignment. Further, the receiving sleeve 30 has two radial recesses 39a, 39b, by means of which the clamping frames 33a, 33b are pivotally mounted in the receiving sleeve 30.

FIG. 5 shows a sectional view of the clamped by the two clamping frames 33a, 33b square 20. Each of the clamping frames 33a, 33b has a corresponding recess 34a, 34b, which together form the passage opening 38 of the clamping device. Further, each clamping frame 33a, 33b, a clamping surface 35a, 35b, which is arranged in the assembled state of the actuating handle 1 a side surface of the square pin 20 opposite. In the illustrated embodiment, each clamping surface 35a, 35b comprises a clamping projection 36a, 36b, which projects beyond the remaining part of the clamping surface 35a, 35b, wherein the clamping projection 36a, 36b in an pivoting direction of the clamping frame 33a, 33b against this is made angled. Furthermore, each of the clamping frames 33a, 33b has a fastening projection 37a, 37b, which can be inserted into respective radial recesses 39a, 39b of the receiving sleeve 30. In this case, the fit of the fastening projections 37a, 37b in the radial recesses 39a, 39b is such that the clamping frames 33a, 33b are pivotally mounted in the receiving sleeve 30.

In the initial position of the clamping device, in which the first clamping frame 33a and the second clamping frame 33b have a first angle α1 (see FIG FIG. 6c ), a distance of the first clamping surface 35a and the first clamping projection 36a to the second clamping surface 35b and to the second clamping projection 36b of the second clamping frame 33b is a predetermined value A. A cross-sectional width B of the square 20 is greater than the distance A. between the first and second clamping surfaces of the two clamping frames.

From the FIGS. 6a to 6d the operation and the assembly of the actuating handle 1 according to the invention can be seen. It is in the FIGS. 6a to 6d a modification of the actuating handle 1 shown, which does not comprise a fastening sleeve 50, but in which the receiving sleeve 30 is inserted directly into the recess 11 'of the handling part 11 and connectable to this. These locking balls 42, which can engage in a radial cutout 11 "of the recess 11 ', are provided for fastening the actuating handle 1. These locking balls 42 also serve for a smooth and exact guidance for the driver element 20 when it is inserted into the receiving sleeve 30. However, these locking balls 42 and the radial recess 11 "are only optional and not required for the subject of the invention. The rest of the design and operation of the in the FIGS. 6a to 6d shown actuating handle 1 is identical to that in the FIGS. 1 to 3 illustrated actuating handle. 1

In FIG. 6a the actuating handle 1 is shown in a still partially disassembled state in which the Receiving sleeve 30 is not inserted into the recess 11 'of the handling part 10, and in which the driver element 20 is not yet inserted into the receiving sleeve 30.

In FIG. 6b the receiving sleeve 30 is pushed into the neck portion 11 of the handling part 10, wherein the locking balls 42 are not yet engaged in the radial recess 11 "of the recess 11 ' FIG. 6b the square pin 20 is not yet inserted into the receiving sleeve 30.

In FIG. 6c the square pin 20 is partially pushed through the receiving opening 31 into the receiving sleeve 30, so that the square pin 20 presses the locking balls 42 radially outward, so that the locking balls 42 engage in the radial recess 11 "However, the square pin 20 is not so far into the receiving sleeve 30, that the square pin 20 protrudes through the through-hole 38 of the clamper 16. The first clamp frame 33a and the second clamp frame 33b close in the in FIG. 6c illustrated starting position of the clamping device a first angle α1 of 180 °.

In FIG. 6d the actuating handle 1 is shown in a completely assembled state, in which the square pin 20 protrudes through the receiving sleeve 30. Since the cross-sectional width B of the square pin 20 is larger than the mutual distance of the first and second clamping surfaces 35a, 35b in the home position, the square pin 20 pushes the first clamping frame 33a and the second clamping frame 33b out of the home position out. Here, the first clamping frame 33a is pivotable about a first pivot axis and the second clamping frame 33b about a second pivot axis in opposite pivot directions. Both the first pivot axis and the second pivot axis are each oriented perpendicular to the insertion direction R and arranged offset parallel to each other. By inserting the square pin 20 in the insertion direction R into the receiving sleeve 30 and through the passage opening 38 of the clamping device, the first clamping frame 33a about the first pivot axis and the second clamping frame 33b pivoted about the second pivot axis, so that the first clamping frame 33a and the second clamping frame 33b include a second angle α2 smaller than the first angle α1, so that the distance A between the first clamping surface 35a and the second clamping surface 35b increases. The coil spring 40 exerts on the clamping device one of the insertion direction R oppositely directed force, so that the clamping device is subjected to force in the direction of its initial position and the clamping surfaces 35a, 35b and the clamping projections 36a, 36b press on the side surfaces of the square 20.

In FIG. 3 the actuating handle 1 according to the invention in the assembled state is shown in a perspective partial sectional view, and in FIG. 4 is a detailed view of the interior of the actuating handle 1 according to the invention in the assembled state shown without operating part 10, wherein the receiving sleeve 30 is shown in section.

Out FIG. 4 the directions of pivoting of the first clamping frame 33a and the second clamping frame 33b can be seen, when the square pin 20 is passed through the passage opening 38 of the clamping device.

The door handle 10 can not be pulled down by the square pin 20, as by a force exerted on the door handle 10 and the insertion direction R opposite tensile force of the first clamping frame 33 a and the second clamping frame 33 b due to the contact of the first clamping surface 35 a and the first clamping projection 36 a and the second clamping surface 35b and the second clamping projection 36b with the driver element 20 on the driver element 20 a the removal of the handling member 10 from the driver element 20 counteracting holding force exert. For when pulling out the driver element 20 from the receiving sleeve 30, the clamping frame 33a and 33b would have to pivot back into their starting position, which is not possible because the respective clamping surfaces 35a, 35b via the clamping projections 36a, 36b with the side surfaces of the driver element 20 in clamping contact stand.

By inserting a release tool through the release tool openings 13, 13 ', the clamping frames 33a, 33b can be pivoted even further, so that the square pin is no longer clamped by the clamping device and the actuating member 10 can be removed from the square pin.
