Description

The invention relates to an actuating handle for a door or a window according to the preamble of claim 1.

Actuation handles for doors and windows are well known. They have a stop body which can be fixed to a door leaf or a frame profile, and a handle which is axially fixed rotatably mounted in the stop body and the opening or closing of the door or the window via a driver with an actuator in the door leaf or in the Frame profile is operatively connected, for example, with a locknut or a gearbox.

In order to facilitate the finding of functional positions of the actuating handle, latching means are provided between the handle and the stopper body, which upon reaching a defined angular position (functional position) of the handle relative to the stopper body in such a way engage each other that the torque required for further rotation of the handle in such a functional position is greater than the torque required for turning outside the functional positions. The latter are thus clearly noticeable to the user. The locking means are usually circumferentially formed in or on a handle attached to the handle neck or in a rotatably connected locking disc and corresponding in the stopper body. These are usually locking lugs, latching projections, locking balls o. The like., Which engage radially and spring loaded in corresponding locking recesses (see for example DE 297 03 682 U1 or DE 20 2008 005 829 U1 ).

DE 42 27 973 C3 however, uses axially acting locking means. For this purpose, a handle with a neck bearing part is rotatably mounted in a bearing sleeve, wherein an actuating shaft approach (square pin) of the handle engages in a closure actuating element which is rotatably mounted in a fitting housing. The neck bearing part consists of a collar sleeve which is axially displaceably mounted on the actuating shaft projection and which is acted on by a helical spring surrounding the actuating shaft shoulder and supported in the grip neck of the handle. The collar sleeve rotatably mounted on the square pin and the bearing sleeve fixed against rotation in the door leaf are designed as axially acting latching parts, wherein the collar sleeve and the bearing sleeve are provided at their mutually facing end surfaces with locking means, preferably with radial ribs which engage in corresponding radial grooves.

DE 33 20 192 C2 used in a door fitting as latching and restoring means axially rising wedge portions which are frontally formed on a axially, but rotatably against a spring in the handle neck mounted sleeve. The wedge sections engage in complementary wedge sections of a guide collar, which is fixed against rotation by means of a screw in the stop body. As a result, the handle is always acted upon independently of the associated lock in the direction of the closed position with a restoring force, so that the lock and the handle always automatically return to their original position. The axially displaceably mounted sleeve is secured by means of two lateral projections in the handle neck against rotation.

DE 10 2011 008 758 A1 proposes to shift the axially movably mounted latching means in the stopper body. For this purpose, a first locking means on a stop body facing the end face of the handle neck is formed, while within the stop body concentric with the axis of rotation a receptacle is provided in which a slider is mounted axially displaceable parallel to the axis of rotation with a second locking means. The slider is in Towards the handle neck acted upon by a spring force, wherein the second locking means engages in the functional positions of the handle with the first locking means in engagement. For this purpose, a spring assembly is arranged between the slider and the bottom of the receptacle, which permanently presses the slider against the end face of the handle neck.

The previously known actuating handles or fittings have the disadvantage that sometimes complicated special components are necessary, which are usually complicated and expensive to manufacture and must be used in special recesses in the door or in the window. Thus, another major disadvantage of the known solutions is that the assembly of the actuating handles on standard doors or standard window profiles is not possible because the predetermined holes in defined bores or recesses can not be used. There are therefore always different from the standard special solutions or additional special holes necessary, which precludes a broad and cost-effective application of the operating handle. Moreover, always separate recesses must be introduced in the handle neck, which further adversely affects the production costs. A quick and cost-effective installation of actuation handles on a standard door or a standard window is therefore not possible.

A further problem is that for the disassembly of the actuating handle partially special tool is required, which must be inserted laterally into an engagement opening in the transmission in order to operate the securing member of the square pin can. Such openings are not provided in standard gearboxes and standard window profiles. Another problem is that the axially displaceably mounted elements can tilt or jam easily, which can affect the overall locking function and thus the function of the actuating handle.

The aim of the invention is to overcome these and other disadvantages of the prior art and to provide an actuating handle, which is constructed inexpensively by simple means and which can be mounted quickly and easily on standard or standard doors. The actuating handle should also be economically producible and have a permanently high stability and reliability in use. Another object of the invention is to develop an actuating handle with a stopper body for a door and / or window handle, which is constructed inexpensively by simple means and at significantly reduced height of the stopper body optically uniform and closed Appearance guaranteed. The stop body should also be easy to handle and withstand higher loads permanently.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 16.

• ▪ dass in dem Griffhals eine Führungshülse ausgebildet ist, die zentrisch zur Drehachse des Griffs den Mitnehmer drehfest aufnimmt und die an ihrem Innenumfang mit Führungselementen versehen ist,
• ▪ dass der Rastring zentrisch zur Drehachse des Griffs eine zu dem Mitnehmer formgleiche Öffnung hat und an seinem Außenumfang mit Führungselementen versehen ist, und

In an actuating handle for a door or a window, having a handle which has a handle neck and which is rotatably connected to a Anschlagköper, wherein the handle is operatively connected via a driver with an actuating element in the door or in the window, and wherein the Stop body on the door or the window can be fixed, and with latching means, which in at least one functional position of the handle non-positively and / or positively engage with each other, wherein a first locking means is formed on a locking ring, which is displaceable in the axial direction and rotationally fixed in the handle neck is mounted, wherein a corresponding to the first latching means formed second latching means is formed on a counter-latching ring which is fixed against rotation on the stopper body, and wherein a compression spring is arranged in the handle neck, which presses the latching ring in the axial direction against the counter-latching ring, provides the invention,

• ▪ that in the handle neck, a guide sleeve is formed, which rotatably receives the driver centric to the axis of rotation of the handle and which is provided on its inner circumference with guide elements,
• That the locking ring has an opening which is identical in shape to the axis of rotation of the handle and has guide elements on its outer circumference, and
• ▪ that the locking ring is inserted into the guide sleeve, wherein the opening receives the driver and wherein the guide elements are axially displaceable with the guide elements of the guide sleeve in engagement.

Due to the arrangement of the locking ring in the handle neck of the handle and the arrangement of the counter-locking ring on the stop body are no more movable locking elements in the stop body, which can therefore be made very flat. Moreover, no latching or counter-locking elements are more accommodated in the door leaf or in the profile frame, so that the actuating handle according to the invention are always mounted on a standard door or a standard window. The guide sleeve used in the handle neck ensures an extremely stable and precise axial bearing and axial guidance of the locking ring, wherein its formed on the outer circumference guide elements with the guide elements on the inner circumference of the guide sleeve are engaged, while the locking ring with his centric opening surrounds the driver. The actuating handle according to the invention thus ensures in use a permanently high stability and reliability, because the locking ring is optimally secured against rotation and can not tilt or jam during its axial movement within the guide sleeve. The central opening in the locking ring for the driver ensures that the locking disk can not be inserted incorrectly into the guide sleeve. The actuating handle is also economical to produce, because the guide sleeve can be made uniform and used in a variety of handles.

An embodiment of the invention provides that the handle neck is provided at the end with a recess for receiving the guide sleeve, and that the guide sleeve is provided on its outer circumference at least partially with a polygonal, such as polygonal outer contour, wherein the recess in the handle neck with a to the Outer contour of the guide sleeve is provided with the same shape inner contour. As a result, the guide sleeve is always secured against rotation and stable in the grip, which further has a favorable effect on the stability and reliability of the actuating handle.

In order to fix the guide sleeve in the handle neck, the outer contour of the guide sleeve is distributed over the circumference in the corner areas is provided with outwardly open recesses. In this area, the guide sleeve can be caulked in the handle neck. Additionally or alternatively, the guide sleeve can be fixed in the handle neck by pressing or by gluing.

It is furthermore advantageous if the guide sleeve has a passage opening which is identical in shape to the driver centrally in relation to the axis of rotation of the handle. The driver is thus always aligned centric and stable in the guide sleeve. The driver also protrudes through the guide sleeve into the handle, so that the driver is always stable and securely fixed.

So that the locking ring is always reliably pressed against the counter-locking ring to hold the handle in the excellent functional positions, the compression spring for the locking ring is supported on a bottom surface of the guide sleeve. This bottom surface may also be formed as an annular surface.

An important embodiment of the invention provides that the handle neck has a stop surface facing the end face and that the inserted into the handle neck Guide sleeve is substantially flush with the end face of the handle neck. The end face of the handle neck, when the handle is mounted on the stopper body, used as a bearing and support surface, which contributes to the high stability and reliability of the actuating handle, because the handle is thereby permanently and stably guided on the stopper body.

The guide elements for the latching ring formed on the inner circumference of the guide sleeve are preferably axially extending, radially inwardly projecting longitudinal ribs which are distributed equidistantly over the inner circumference of the guide sleeve, while the guide elements formed on the outer circumference of the latching ring extend radially in the axial direction are inwardly directed longitudinal grooves. Preferably, four longitudinal ribs and four longitudinal grooves are provided, which are arranged distributed in equidistant intervals over the circumference. Particularly preferred to use eight longitudinal ribs and longitudinal grooves, which results in a particularly precise and stable storage for the locking ring. If necessary, even more guide elements can be formed.

The axial length of the longitudinal ribs of the guide sleeve is preferably greater than the axial length of the longitudinal grooves of the locking ring. In this way it is ensured that the locking ring can move freely in the axial direction within the guide sleeve.

Thus, the excellent functional positions of the handle on the stopper body for the user of the actuating handle are clearly visible, the first locking means is formed by at least two locking recesses which are distributed in equidistant intervals over the circumference in a stop body facing the end face of the locking ring, while the second latching means are at least two locking projections corresponding to the latching recesses, which are distributed in equidistant intervals over the circumference in a handle facing the end face of the counter-locking ring. In order to increase the recognizability of the functional positions, four or more preferably eight locking recesses and locking projections may be provided, which are always formed in pairs on the locking ring and the counter-locking ring.

A further advantageous embodiment of the invention provides that the stop body has a base body which is provided centrally with respect to the axis of rotation of the handle with a recess for receiving the counter-locking ring and with at least two through holes for receiving fastening screws, wherein the base body has an upper side and a lower side , Such a basic body can, for example, as simple and stable Plate are formed extremely flat, so that the stopper body has a total of only a very small height. As a result, highest aesthetic demands can be met with the actuation handle according to the invention, even on standard doors and standard windows.

Advantageously, the counter-locking ring is positively inserted into the recess of the base body and secured by means of fitting elements against rotation. For this purpose, the counter-locking ring on its side facing away from the end face as the first fitting element, for example, at least two axial projections which engage positively in the recess of the base body. For this purpose, in turn, it is expedient if the axial projections of the counter-locking ring are provided on their outer circumference, each with a recess. The recess in the base body, however, is provided on its inner circumference with at least two radial projections, which form the second fitting element. The projections are formed corresponding to the recesses in the axial projections of the counter-locking ring. As a result, the counter-locking ring is not only secured against rotation, but always kept stable and reliable in the main body of the stopper body. He is also simply used in the body. Additional fixing elements or assembly steps are not necessary.

The invention further provides that the recess in the main body between the radial projections further radial projections which lie after insertion of the counter-locking ring in the recess of the base body between the axial projections of the counter-locking ring. The counter-locking ring is thus always reliable and stable supported by the body, which has a favorable overall effect on the stability of the stopper body.

In order to hide the base body and the fastening screws inserted therein after assembly of the actuating handle, the stop body on a cover, which is rotatably arranged on the upper side of the base body and in a first rotational position relative to the base body covers this and in a second rotational position relative to Body releases the through holes. The cover has in this case centric to the axis of rotation of the handle an opening in which a flange is inserted. With this, the cover is rotatably secured to the body.

It is important here that the flange ring by means of fitting elements secured against rotation with the counter-locking ring engages. In this way you prevent that the cover when operating the handle accidentally with rotates. For this purpose, for example, the flange ring has a ring section which projects through the opening in the cover element and engages in a positive engagement with the counter-latching ring, wherein the flange ring is provided on its inner circumference as a second fitting element with at least two radial projections which correspond to the first fitting element, thus correspondingly the recesses are formed in the axial projections of the counter-locking ring. This simplifies the design effort considerably, because even for the flange in the body no separate fitting or support elements are necessary. This encloses the counter-locking ring and uses the fitting elements that hold the counter-locking ring against rotation in the body of the stopper body.

To secure the cover axially, the flange has a flange, which rests in the region of the opening in the cover on the top. As a result, the cover is secured axially on the body. At the same time the flange edge forms an abutment and a sliding bearing for the handle. For this purpose, it is important that the flange of the flange has a flat face, the end face forms a bearing surface for the handle or the handle neck. If the handle, in which the end face of the driver is inserted, axially fixed on the stopper body, the handle neck of the handle can rest flush with its end face on the flange of the flange, so that the handle is permanently stable and precisely mounted on the stopper body. The axial fixation of the handle, for example, by means of one or two clamping discs, which are frictionally and / or frictionally mounted on the driver and which are supported from below against the underside of the main body of the stopper body. The rotation of the flange with respect to the base body is effected by the complementary fitting elements which are formed corresponding to the flange and the counter-locking ring.

In an advantageous embodiment of the invention, a cover lower part is arranged on the underside of the base body, wherein the cover member and the cover lower part in the first rotational position of the cover enclose the base body. In this case, the cover has a side covering the body edge, which is interrupted in opposite areas. Likewise, the cover lower part has a side covering the body edge, which is interrupted in opposite areas, wherein the edge of the cover and the edge of the cover base in the first rotational position of the cover complement each other relative to the base body to an optically closed edge ,

This results in a low overall height of the stopper body always visually uniform and closed appearance for the actuating handle, because the cover and the cover lower part close the body with which the handle is attached to the door or window, such as a housing in a, so that the body is not visible from the outside. For assembly or disassembly of the main body, however, the cover can be rotated at any time in the second rotational position relative to the main body, so that the through holes in the body and - if available - the mounting screws are accessible. In this case, the cover must not be raised relative to the base body or with respect to the handle, because the cover always moves in a plane, namely in the plane of the cover lower part, which is arranged immovably under the body. Consequently, the distance between the handle and the cover can be reduced to a minimum, because between the handle and the body no spring or locking elements are more necessary to hold the cover on the body. The stopper body according to the invention is simple and inexpensive and can be handled easily.

The edges of the cover member and cover base are complementary, i. the edge of the cover is in the closed position of the cover in the opposite regions between the edge of the cover bottom and vice versa. Both edges thus complement each other to a visually self-contained edge as soon as the cover has taken on the lower part of its first closed rotational position, with the cover and the cover lower part are always at the same height. The height of the edge is dependent on the height of the base body, in particular adapted to the height thereof, so that the main body is always completely - also laterally - surrounded by the further pivotable cover member and the cover lower part.

In terms of construction, it is favorable if the cover lower part has a base in which an opening is formed centrally in relation to the axis of rotation of the handle and through holes for the fastening screws are formed in the region of the through holes of the main body.

The cover and the cover lower part are in the first rotational position of the cover force, friction and / or positive locking together. As a result, the cover always remains safe in the first rotational position, ie it can not accidentally twist during operation of the handle. The connection can either through Locking elements are created, which are formed on the one hand on the cover and on the other hand on the cover lower part. Or one uses suitable clamping or friction elements, which fix the cover to the cover lower part releasably.

In the Fig. 1 Generally designated 10 actuating handle is designed as a window fitting. It serves to open, close or tilt a window (not shown) equipped with a tilt-and-turn fitting. For this purpose, a (also not shown) Drehkipp mechanism is integrated within the window or within the window sash, which can be actuated via the actuating handle 10. The latter has a handle 20 with a handle body 21 and a handle neck 22 which is rotatably mounted about a rotation axis D on a stopper body 40 and a driver 30, preferably a square pin, with a rotatably mounted in the sash (not shown) actuator of the tipping -Mechanik is in operative connection. The actuating element of the tilt-turn mechanism is preferably a gearbox, which is provided centrally with a square recess, which receives the free end of the square pin 30 in a form-fitting manner.

The handle neck 22 has a recess 23 aligned centrally with respect to the rotation axis D and open towards the stop body 40, which receives the driver 30 in an inner region 231 and a guide sleeve 80 in a front region 232. The inner region 231 of the recess 23 has a cross section corresponding to the cross section of the driver 30, so that the driver 30 can be fixed in the grip neck 20 in a rotationally fixed manner. The front region 232 of the recess 23 is provided with a polygonal, preferably octagonal inner contour 24.

In the Fig. 2 shown guide sleeve 80 has at its outer periphery 81 to the octagonal inner contour 24 of the recess 23 corresponding also octagonal outer contour 82, so that the guide sleeve 80 is rotatably held in the recess 23. The outer contour 82 of the guide sleeve 80 has distributed over the circumference in the corners eight open recesses 83. In these areas, the guide sleeve 80 is caulked after insertion into the recess 23 with the handle neck 22, as in Fig. 3 is shown. The guide sleeve 80 is - like Fig. 3 further shows - flush inserted into the handle neck 22, wherein the end face 88 of the guide sleeve 80 substantially flush with the stop body 40 facing end face 26 of the handle neck 22 terminates. It is important that the guide sleeve 80 with its end face 88 does not protrude beyond the end face 26 of the handle neck 26. For the implementation of the driver 30 is in the guide sleeve 80 centric to the axis of rotation D of the handle 20 an identical to the driver 30 through hole 84 is formed so that the driver 30 can be inserted through the guide sleeve 80 into the inner region 231 of the recess 31.

The inner circumference 86 of the guide sleeve 80 is substantially cylindrical, wherein on the inner circumference 86 guide elements 87 are formed. These are longitudinal ribs which extend in the axial direction A and project radially inwards, so that longitudinal grooves 89 extending in the axial direction A are likewise formed between the longitudinal ribs 87. The longitudinal ribs 87 and the longitudinal grooves 89 extending parallel thereto are arranged at equidistant intervals and evenly distributed over the inner circumference 86 of the guide sleeve 80. In the embodiment of Fig. 2 a total of eight longitudinal ribs 87 and eight recesses 89 are provided. But you can also choose a different number. All longitudinal ribs 87 have a length L in the axial direction A. They end - as in the Fig. 2 and 3 to see - in front of the end face 88 of the guide sleeve 80th

Between the handle 20 and the stopper body 40, a latching device is formed, the axially acting latching means 52, 62, which in at least one functional position of the handle 20 non-positively and / or positively engage with each other. A first latching means 52 is formed on a latching ring 50, which is mounted in the axial direction A displaceable and rotationally fixed in the guide sleeve 80 in the handle neck 22. A corresponding to the first latching means 52 formed second latching means 62 is formed on a counter-latching ring 60 which is non-rotatably and non-displaceably inserted into the stopper body 40.

The locking ring 50 is an axially displaceable arranged in the guide sleeve 80 annular disc with a central and to the driver 30 form-fitting opening 54. The latter serves to accommodate the driver 30, wherein the dimensions of the opening 54 are selected such that the driver 30 during the latching movement of the latching ring 80 can move within the guide sleeve 80 without tilting in the opening 54. On its outer circumference 56, the locking ring 80 carries guide elements 57, which are formed corresponding to the guide elements 87, 89 in the guide sleeve 80. These are, for example, radially inserted into the outer circumference 56 guide grooves 57, which have a length I in the axial direction A and are dimensioned such that the guide elements 87 of the guide sleeve 80 can slide therein, i. the guide elements 57 of the locking ring 50 are axially displaceable with the guide elements 87 of the guide sleeve 80 in engagement. The guide grooves 57 are arranged distributed at equidistant intervals over the outer circumference 56 of the locking ring 50, wherein the number of guide grooves 57 corresponds to the number of longitudinal ribs 87.

The first latching means 52 are, for example, latching recesses which are distributed over the circumference at equidistant intervals in an end face 51 of the latching ring 50 facing the stopper body 40. For example, a total of eight latching recesses 52 are formed in the locking ring 50, which are provided in the circumferential direction with slightly inclined side walls 53.

The second latching means 62 are latching projections which are formed corresponding to the latching recesses 52 in the latching ring 80 at equidistant intervals over the circumference in an end face 61 of the counter-latching ring 60 facing the handle 20. For example, a total of eight locking projections 62 are formed on the counter-locking ring 60, which are provided in the circumferential direction with slightly inclined side edges 621. Between the locking ring 50 and the guide sleeve 80, a compression spring 70 is arranged, which presses the locking ring 50 in the axial direction A permanently against the counter-locking ring 60. In this case, the compression spring 70 is supported on a bottom surface 85 in the guide sleeve 80 and on the back 55 of the locking ring 50. Depending on the size of the compression spring 70 can - as in Fig. 1 shown - in the guide sleeve 80 an additional (unspecified) annular recess for receiving the compression spring 70 may be provided. The bottom 85 is in this case at the inner end of this recess.

So that the locking ring 50 can slide freely in the guide sleeve 80 over the entire latching stroke of the latching elements 52, 62, the axial length L of the longitudinal ribs 87 of the guide sleeve 80 is greater than the axial length I of the longitudinal grooves 57 of the locking ring 50, wherein both the axial length L of the longitudinal ribs 87 and the axial length I of the longitudinal grooves 57 is greater than the (not specified) axial height of the locking elements 52, 62. Deren height defines the latching stroke and thus the travel of the locking ring 50 within the guide sleeve 80th

The stopper body 40 has - like the Fig. 4 and 5 show a base body 41 with a centrally aligned with the axis of rotation D of the handle 20 recess 42 and two symmetrically arranged through holes 46 which are provided for receiving fastening screws (not shown). With the fastening screws, which are preferably flat head screws, the stopper body 40 is fixed to the window sash. The recess 42 in the base body 41 serves for non-rotatably receiving the counter-latching ring 60, wherein this is positively inserted into the recess 42 and secured by means of fitting elements 44,64 against rotation. The main body 41 is preferably formed as a flat plate having an upper side 47 and a lower side 48.

The counter-locking ring 60 is formed as an annular disc, which has a central opening 67 for the driver 30, so that this - with mounted handle 20 - can engage through the counter-locking ring 60 into the actuating element of the tilt-turn mechanism in the window sash. On the handle 20 and the locking ring 50 of the locking device facing end face 61 carries the counter-locking ring 60, the locking projections 62 which are arranged opposite to the locking recesses 52 of the locking ring 50 at equidistant angular intervals.

On the opposite, the handle 20 facing away from back 63 60 four axial projections 64 are formed on the counter-locking ring, which are each provided at its outer periphery 65 with a recess 66. With these axial projections 64 engages the Counter-locking ring 60 in the central recess 42 of the main body 41, which is provided on its inner circumference 43 respectively in the region of the axial projections 64 with the depressions 66 opposite radial projections 44. It can be seen that the axial projections 64 on the counter-locking ring 60 each form a first fitting element and the radial projections 44 on the inner circumference 43 of the recess 42 each form a second fitting element which - as soon as the counter-locking ring 60 is inserted into the recess 42 of the main body 41 - in pairs positively grab and form in this way a rotation for the counter-locking ring 60.

On the inner circumference 43 of the recess 42 further radial projections 45 are formed, which lie after the insertion of the counter-locking ring 60 in the base body 41 radially between the axial projections 64 of the counter-locking ring 60. In this way, the counter-latching ring 60 is supported by the radial projections 45, i. the main body 41 forms a solid support for the counter-locking ring 60, which is held immovably in the base body 41 in the axial direction and in the circumferential direction and is in engagement with the locking ring 50, which is axially movable and likewise immovably guided in the guide sleeve 80 in the circumferential direction.

Above the main body 41 is a cover member 90 which is rotatably disposed on the upper side 47 of the main body 41 and in a first rotational position relative to the main body 41 covers this (see Fig. 7 ). In a second rotational position relative to the main body 41, the cover 90 releases the through holes 46, so that the stopper body 40 can be mounted with the mounting screws - or the screws can be solved unhindered for disassembly (see Fig. 6 ).

The cover 90 lies flat on the plate 41 and is concentric with the recess 42 of the body 41 provided with a central opening 95. It is rotatably mounted on the base body 41 with a flange ring 110. The flange 110 preferably has a ring portion 112, the - like Fig. 1 shows - is supported in the axial direction on the base body 41 and the opening 95 extends through the cover 90. It encloses the counter-locking ring 60 and is rotatably connected thereto by means of further fitting elements 114. These are on the inner circumference of the flange ring 110 - like Fig. 5 shows closer - radial projections 114 are provided, which are formed opposite to the recesses 66 in the axial projections 64 of the counter-latching ring 60, ie the further projections 114 of the flange 110 and the recesses 66 of the counter-latching ring 60 also form pairs of fitting elements to to secure the flange 110 against rotation. In this way, the cover 90 can always be freely pivoted and relative to the base body 41 laterally.

In order to secure the cover element 90 axially, the flange ring 110 has a flange edge 115 which rests in the region of the opening 95 in the cover element 90 on its upper side 91. The flange edge 115 of the flange ring 110 in this case preferably has a flat end face 116, wherein the handle neck 22 with mounted handle 20 with its end face 26 slidably rests on the end face 116 of the flange 110 and is supported by this.

The axial fixing of the handle 20 to the stopper body 10, for example, with a clamping element K, which is firmly placed on the driver 30, preferably pressed. The clamping element K is in this case non-positively and / or frictionally engaged with the side walls of the driver 30 and is supported on the underside 48 of the main body 41 from. In this way, the handle 20 is pulled with its end face 26 against the end face 116 of the flange 110, wherein the handle neck 22 rests flush and stable on the flange edge 115. As a result, the handle 20 is permanently stable and precisely mounted on the stopper body 10. The end face 26 of the handle neck 22 and the end face 116 of the flange 110 form a sliding bearing for the handle 20, which can be easily and precisely rotate about its axis of rotation D. It can be seen that only the flange edge 115 of the flange ring 70 is between the handle neck 22 and the cover 90, so that the gap between the handle 20 and cover 90 is reduced to a minimum and is barely visible from the outside. In order to increase the strength of the connection between the handle 20 and the stopper body 40, as in Fig. 1 shown - two clamping disks K are used.

To stabilize the pivotal mounting of the handle 20 on the stopper body 40 contributes when the counter-locking ring 60 edge has a peripheral edge 68, which - like the Fig. 1 and 4 show - stepped from the end face 61 and is flush with the end face 116 of the flange 110 completes. In this way, results for the handle neck 22 and the guide sleeve 80 is preferably flush inserted therein an enlarged support and bearing surface, wherein the end face 26 of the handle neck 22 rests on the end face 116 and the peripheral edge 68.

On the underside 48 of the main body 41, a cover lower part 100 is formed, wherein the cover member 90 and the cover lower part 100 in the first rotational position of the cover 90 surround the base body 41 together.

The cover lower part 100 has a bottom 105 in which an opening 106 is formed concentrically with the recess 42 of the main body 41. The diameter of the opening 106 is preferably larger than the outer diameter of the clamping disks K, so that they can be supported on the underside 48 of the main body 41 unhindered. In the region of the through holes 46 of the main body 41, through holes 107 are formed in the bottom 105 of the cover lower part 100, so that the main body 41 can be fastened to the window sash with the fastening screws. The main body 41 lies flat on the bottom 105 of the cover base 100, resulting in a stable arrangement.

To also include the body 41 laterally, i. optically cover or cover, the cover 90 and the cover base 100 form a common circumferential edge 92, 102 which surrounds the body 41 laterally. For this purpose, the cover 90 has a body 41 laterally covering the edge 92 which is interrupted in opposing areas 93, 94. In these areas 93, 94, the cover lower part 100 has a base 102 laterally covering edge 102, which is also interrupted in opposing areas 103, 104, namely where the edge 92 of the cover 90 is formed. As a result, the edge 92 of the cover 90 and the edge 102 of the cover 100 in the first rotational position of the cover 90 complement each other relative to the base body 41 to an optically closed edge, which conceals the base body 41 laterally encircling.

Due to the division of the edge 92, 102, however, it is always possible to rotate the cover 90 relative to the base body 41 and relative to the cover base 100 in a plane laterally to expose the fastening screws or the through holes 46. A lifting or lifting of the cover 90 is not necessary. Also, additional or separate spring elements which press the cover 90 against the base 41, are no longer necessary, because the cover 90 is always kept safe and rotatable about the flange 110.

It can be seen that the cover member 90 and the cover lower part 100 form a kind of housing for the main body 41, which is closed in the first rotational position of the cover 90 in itself and covers the main body 41 from all sides, but at the same time by a simple rotational movement can be opened in a plane to assemble or disassemble the body 41 can. The cover 90 forms a kind Swivel cover for the housing, while the cover lower part 100, which is arranged in the mounted position of the stopper body 40 between the base body 41 and the window sash, forms the housing bottom. The edges 92, 102 complement each other in the closed position to side walls, which cover the body 41 laterally. In the open position form the end edges of the edges 92 of the cover 90 - as in Fig. 6 shown - stops for the rotational movement, so that the cover 90 can be rotated or opened only up to a certain angle. The lengths of the respective edges 92, 102 on the cover element 90 and the cover lower part 100 are matched to one another such that when the cover element 90 is rotated, a sufficiently large opening angle results for exposing the fastening screws or the through-holes 46, and that the edge 92 , 102 acts in the first rotational position of the cover 90 at least optically closed in itself.

So that the cover member 90 can not inadvertently open or twist during use of the handle 20 by its rotational movement, the cover member 90 and the cover lower part 100 in the first rotational position of the cover 90 force, frictionally and / or positively with each other Connection. For this purpose, for example, in the corner regions 101 of the edges 102 of the cover subelement 100, a baffle 108 is formed which holds the cover element 90 in position in the first rotational position. Such a baffle 108 is for example a survey, which is provided at the edge with flat rising flanks 109 as run-on slopes. When turning the cover 90 from the second rotational position to the first rotational position, the cover 90 is slightly raised at the edge, wherein the survey 108 is either frictionally engaged with the cover 90 in contact. Or the cover 90 has on its underside a corresponding (not shown) recess into which the survey 108 engages. The cover 90 itself acts as a spring element.

So that the cover lower part 100 is not lost, as long as the actuating handle 10 is not struck on the door or on the window, the base body 41 and the cover lower part 100 are latched together. For this purpose, two domes 120 are attached to the cover lower part 100, which clamp in two holes 49 of the main body 41 and are latched.

In addition, the cover lower part 100 may be provided with peripheral edge portions 122 which surround the base body 41 laterally and in shape. The width of the edge portions 122 is narrower than the width of the edges 102, so that the cover 90th with its edges 92 can continue to fully enter the first rotational position. In this rotational position, the edge portion 122 are behind the edges 92 of the cover 90. So that the mounting screws flush with the top 47 of the body 41, each through hole 46 of the body 41 forms a depression 461 for receiving a screw head. In order to additionally provide an anti-rotation device for the stopper body 40 on a door leaf or on a window sash 100, cam-like projections 126 are formed on the base body 41 facing away from the rear side 124 of the cover lower part 100. It can be seen that the depressions 461 in the plate 41 and the cam-shaped projections 126 in the cover base 100 complement each other.

The cover element 90 and the cover lower part 100 are preferably center-symmetrical with respect to the center of the recess 42 in the base body 41. This simplifies both the manufacture of the elements 90, 100 and also their handling and assembly. <B> LIST OF REFERENCES </ b> A axially 55 back D axis of rotation 56 outer periphery K clamping element 57 Guide element / longitudinal groove L axial length 60 Gegnerastring I axial length 61 face M Focus 62 Locking means / locking projection 621 side flank 10 Actuating handle 63 back 20 Handle 64 Fitting element / axial projection 21 Handle main part 65 outer periphery 22 handle neck 66 deepening 23 recess 67 opening 231 inner area 68 circumferential edge 232 front area 70 compression spring 24 inner contour 80 guide sleeve 26 face 81 outer periphery 30 takeaway 82 outer contour 40 stop body 83 recess 41 body 84 Through opening 42 recess 85 floor area 43 inner circumference 86 inner circumference 44 Fitting element / radial projection 87 Guide element / longitudinal rib 45 further radial projection 88 face 46 Through holes 89 longitudinal groove 461 lowering 90 cover 47 top 91 top 48 bottom 92 edge 49 drilling 93 Area 50 locking ring 94 Area 51 face 95 opening 52 Locking means / locking depression 100 Covering the lower part 53 sidewall 101 corner 54 opening 102 edge 103 Area 112 inner circumference 104 Area 114 Fitting element / radial projection 105 ground 115 flange 106 opening 116 face 107 Through opening 120 mandrel 108 Chicane / Survey 122 edge section 109 flank 124 back 110 flange 126 cam-like projection
