DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) An actuation handle designated as 10 in FIG. 1 is designed as a window fitting. It is used to open, close, or tilt a window (not shown) that is equipped with tilt and turn fittings. To this end, a tilt and turn mechanism is integrated inside the window and/or inside the window sash (also not shown), which can be operated using the actuation handle 10. The actuation handle 10 is provided with a handle 20 composed of a main handle section 21 and a handle neck 22, which is rotatably mounted on an installation body 40 around a rotary axis D and is in an operative connection with an actuation element (not shown) of the tilt and turn mechanism that is rotatably mounted via a driver 30, which is preferably a square spindle. The actuation element of the tilt and turn mechanism is preferably provided by a gear nut that is centrally equipped with a square recess that serves as a receptacle for the free end of the square spindle 30 in a positive-locking fashion.

(10) The handle neck 22 is provided with a recess 23 that is centrally aligned with the rotary axis D and that is open towards the installation body 40, which serves as a receptacle for the driver 30 in an inner section 231 and a guide sleeve 80 in a front area 232. The inner section 231 of the recess 23 has a cross section that corresponds to the cross section of the driver 30 in such a manner that the driver 30 can be fixed inside the handle neck 20 in a non-rotatable manner. The front section 232 of the recess 23 is provided with a multiangular, preferably octagonal, inner contour 24.

(11) The guide sleeve 80 is shown in detail in FIG. 2, and has an equally octagonal outer contour 82 on its outer circumference 81 that corresponds to the octagonal inner contour 24 of the recess 23 so that the guide sleeve 80 is held inside the recess 23 in a non-rotatable manner. The outer contour 82 of the guide sleeve 80 has eight open recesses 83, which are distributed along its circumference and positioned in the corner areas. In these areas, the guide sleeve 80 may be caulked together with the handle neck 22 after insertion into the recess 23 as is shown in FIG. 3. The guide sleeve 80 isas shown in FIG. 3inserted flush with the handle neck 22, wherein the front surface 88 of the guide sleeve 80 is generally flush with the front surface 26 of the neck section 22 that faces the installation body 40. It is important in this regard that the guide sleeve 80 does not protrude over the front surface 26 of the handle neck 26 with its own front surface 88. To serve as an opening for the driver 30, a passage opening 84 with the same shape as the driver 30 is provided within the guide sleeve 80 and centrally aligned with the rotary axis D of the handle so that the driver 30 can be inserted into the inner section 231 of the recess 31 through the guide sleeve 80.

(12) An inner circumference 86 of the guide sleeve 80 is basically cylindrical in shape, while guide elements 87 are provided along the inner circumference 86. These guide elements 87 are longitudinal ribs, which extend in the axial direction A and radially protrude inwardly, so that longitudinal grooves 89 are provided in the axial direction A between these longitudinal ribs 87. The longitudinal ribs 87 and the parallel longitudinal grooves 89 are distributed along the inner circumference 86 of the guide sleeve 80 at equidistant intervals. As shown in the embodiment example of FIG. 2, a total of eight longitudinal ribs 87 and eight recesses 89 are provided. However, it would also be feasible to use a different number. All of the longitudinal ribs 87 are equal to a length L in the axial direction A. They endas shown in FIGS. 2 and 3in front of the front surface 88 of the guide sleeve 80.

(13) A detent mechanism is provided between the handle 20 and the installation body 40, which is equipped with axially-acting detent elements (detent recesses 52, detent projections 62) that engage with each another in a force-locking and/or positive-locking manner in at least one functional position of the handle 20. The first detent element or detent recess 52 is provided on a detent ring 50, which is mounted inside the guide sleeve 80 of the handle neck 22 in such a manner that it is movable in the axial direction A and is non-rotatable with respect to the guide sleeve 80. A second detent element or detent projection 62 that corresponds to the first detent recess 52 is provided on an counter detent ring 60, which is inserted into the installation body 40 in a non-movable and non-twisting manner.

(14) The detent ring 50 is a disc with a centrally positioned opening 54 in the same shape as the driver 30 that is positioned inside the guide sleeve 80 in an axially movable fashion. This opening is used as a receptacle for the driver 30, wherein the dimensions of the opening 54 are selected in such a way that the driver 30 can move inside the guide sleeve 80 without being jammed in the opening 54 during the detent movement of the detent ring 80. The detent ring 80 is provided with guide elements 57 along its outer circumference 56, which correspond to the guide elements 87, 89 in the guide sleeve 80. These could, for example, be guide grooves 57 that are radially positioned along the outer circumference 56 corresponding to a length I in the axial direction A and are dimensioned in such a way that the guide elements 87 of the guide sleeve 80 can glide within these, meaning that the guide elements 57 of the detent ring 50 are engaged with the guide elements 87 of the guide sleeve 80 in an axially movable manner. The guide grooves 57 are distributed along the outer circumference 56 of the detent ring 50 at equidistant intervals, wherein the number of guide grooves 57 corresponds to the number of longitudinal ribs 87.

(15) This first detent element 52 could, for example, be provided by detent recesses 52, which are distributed along the circumference at equidistant intervals along the front surface 51 of the detent ring 50 facing the installation body 40. As an example, it might be feasible to provide the detent ring 50 with a total of eight detent recesses 52, which are, in turn, provided with slightly oblique side walls 53 in the circumferential direction.

(16) The second detent element 62 could be provided by detent projections 62, which are distributed along the circumference of the front surface 61 of the counter detent ring 60 at equidistant intervals and which correspond to the detent recesses 52 in the detent ring 80. As an example, it might be feasible to provide the counter detent ring 60 with eight detent projections 62, which are, in turn, provided with slightly oblique side walls 621 in the circumferential direction.

(17) A compression spring 70 is positioned between the detent ring 50 and the guide sleeve 80, which permanently pushes the detent ring 50 against the counter detent ring 60 in the axial direction A. This compression spring 70 is supported by a bottom area 85 within the guide sleeve 80 and the rear side 55 of the detent ring 50. Depending on the size of that compression spring 70as shown in FIG. 1it might be feasible to provide an additional circular recess (not designated separately) to serve as a receptacle for the compression spring 70 inside the guide sleeve 80. The bottom area 85 is located at the inner end of this recess in this case.

(18) To allow the detent ring 50 to glide within the guide sleeve 80 along the entire detent stroke of the detent elements 52, 62, the axial length L of the longitudinal ribs 87 of the guide sleeve 80 is larger than the axial length l of the longitudinal grooves 57 of the detent ring 50, wherein both the axial length L of the longitudinal ribs 87 as well as the axial length I of the longitudinal grooves 57 are larger than the axial height (not designated separately) of the detent elements 52, 62. That height defines the detent stroke and thereby the travel range of the detent ring 50 within the guide sleeve 80.

(19) The installation body 40 isas shown in FIGS. 4 and 5composed of a base body 41 with a recess 42 that is centrally aligned with the rotary axis D of the handle 20 and two passage holes 46 that are arranged symmetrically and which are provided for the purpose of receiving fastening screws (not shown). These fastening screws, which are preferably flat-head screws, are used to fasten the installation body 40 to the window sash. The recess 42 inside the base body 41 is used as a non-rotatable receptacle for the counter detent ring 60, which is inserted into the recess 42 in a positive-locking manner and secured against twisting using fitted keys 44, 64. The base body 41 is preferably designed as a flat plate that consists of a top side 47 and bottom side 48.

(20) The counter detent ring 60 is designed as a disc with a central opening 67 for the driver 30, so that the driver 30 can engage with the actuation element of the tilt and turn mechanism inside the window sash (not shown in the figures) through the counter detent ring 60with the handle 20 mounted. On the front surface 61 facing the handle 20 and the detent ring 50 of the detent mechanism, the counter detent ring 60 is provided with detent projections 62, which are arranged at equidistant angular distances and which match the detent recesses 52 of the detent ring 50.

(21) The counter detent ring 60 is provided with four axial protrusions 64 (each being a first element of the fitted keys) on the rear side 63 facing away from the handle 20, which are, in turn, each provided with a recess 66 at its outer circumference. Using these axial protrusions 64, the counter detent ring 60 engages with the central recess 42 of the base body 41, which is provided with radially protruding lugs 44 (each being a second element of the fitted keys) that are configured oppositely of the recesses 66 and are positioned along the inner circumference 43 in the same areas as the axial protrusions 64. It is apparent that the axial protrusions 64 on the counter detent ring 60 form the first fitted key element while the radial protrusions 44 along the inner circumference 43 of the recess 42 form the second fitted key element, whichas soon as the counter detent ring 60 is inserted into the recess 42 of the base body 41engage with each other in pairs and in a positive-locking manner, thereby securing the counter detent ring 60 from twisting with respect to the base body 41.

(22) The inner circumference 43 of the recess 42 is equipped with further radial protrusions 45, which are positioned radially between the axial protrusions 64 of the counter detent ring 60 after insertion of the counter detent ring 60 into the base body 41. In this manner, the counter detent ring 60 is supported by the radial protrusions 45, meaning that the base body 41 constitutes a solid support measure for the counter detent ring 60, which is axially held inside the base body 41 and is immobile in the circumferential direction as well as is engaged with the axially movable and similarly immobile in the circumferential direction detent ring 50 inside the guide sleeve 80.

(23) A covering element 90 is located above the base body 41, which is rotatably arranged on the top side 47 of the base body 41 and covers the base body 41 in the first rotary position with respect to the base body 41 (also see FIG. 7 in this regard). In the second rotary position with respect to the base body 41, the covering element 90 allows access to the passage holes 46 so that the installation body 40 can be installed using the fastening screwsor the screws can be loosened for disassembly purposes without any problems (also see FIG. 6 in this regard).

(24) The covering element 90 lays flat on the plate 41 and is equipped with a central opening 95 that is, in turn, concentrically aligned with the recess 42 of the base body 41. It is rotatably mounted on the base body 41 via a flange ring 110. The flange ring 110 is preferably provided with an inner circumference 112 that rests on the base body 41 in the axial direction and passes through the opening 95 in the covering element 90as shown in FIG. 1. It then surrounds the counter detent ring 60 and is connected with the ring in a non-rotatable manner using fitted keys 114. To this end, radial protrusions 114 are provided on the inner circumference of the flange ring 110as shown in more detail in FIG. 5which are similar in shape to the recesses 66 inside the axial protrusions 64 of the counter detent ring 60, which means that the other protrusions 114 of the flange ring 110 and the recesses 66 of the counter detent ring 60 also form pairs of fitted key elements in order to prevent the flange ring 110 from twisting. The covering element 90 can therefore be laterally swiveled with respect to the base body 41 without any problem.

(25) In order to axially lock the covering element 90, the flange ring 110 has a flange edge 115 that is in contact with the top side 91 of the covering element 90 in the area of the opening 95 of the covering element. The flange edge 115 of the flange ring 110 is preferably equipped with a flat front surface 116, wherein the handle neck 22 rests on the front surface 116 of the flange ring 110 with its own front surface 26 in a gliding fashion and is supported by the flange ring 110 if the handle 20 is installed.

(26) The axial fixation of the handle 20 on the installation body 10 is preferably achieved using a clamping element K that is firmly positioned on the driver 30 and preferably pressed on the driver 30. The clamping element K is engaged with the side walls of the driver 30 in a force-locking and/or friction-locking manner and is supported on the bottom side 48 of the base body 41. In this manner, the handle 20 is pulled against the front surface 116 of the flange ring 110 with its front surface 26, wherein the handle neck 22 sits flush and stably on the flange edge 115. This results in the handle 20 being stably and precisely mounted on the installation body 10. The front surface 26 of the handle neck 22 and the front surface 116 of the flange ring 110 combine to form a plain bearing for the handle 20, which can easily and precisely be rotated around its rotary axis D. It is apparent that only the flange edge 115 of the flange ring 110 is situated between the handle neck 22 and the covering element 90 so that the gap between the handle 20 and the covering element 90 is reduced to a minimum and therefore barely visible from the outside. In order to improve the strength of the connection between the handle 20 and the installation body 40, it is possible to use two clamping discs Kas shown in FIG. 1.

(27) To stabilize the rotational bearing of the handle 20 on the installation body 40, the counter detent ring 60 can also be provided with a circumferential edge 68, whichas shown in FIGS. 1 and 4is detached from the front surface 61 in a cascading manner and closes flush with the front surface 116 of the flange ring 110. This results in an enlarged support and bearing area for the handle neck 22 and the flush guide sleeve 80, wherein the front surface 26 of the handle neck 22 rests on the front surface 116 of the flange ring 110 and the circumferential edge 68 of the counter detent ring 60.

(28) The bottom side 48 of the base body 41 is provided with a lower covering part 100, while the covering element 90 and the lower covering part 100 jointly surround the base body 41 in the first rotary position of the covering element 90.

(29) The lower covering part 100, in turn, has a bottom 105 with an opening 106 that is concentrically aligned with the recess 42 of the base body 41. The diameter of the opening 106 is preferably designed to be larger than the outer diameter of the clamping elements K so that these can rest on the bottom side 48 of the base body 41 without problems. In the area of the passage holes 46 of the base body 41, passage holes 107 are provided in the bottom 105 of the lower covering part 100 so that the base body 41 can be fastened on the window sash. The base body 41 rests flat on the bottom 105 of the lower covering part 100, which results in an arrangement that is very stable overall.

(30) To achieve an appearance that the base body is also closed on the sides, meaning visually obscured, the covering element 90 and the lower covering part 100 form a joint circumferential edge 92, 102, which laterally surrounds the base body 41. The covering element 90 is provided with an edge 92 that laterally covers the base body 41, which is separated into opposing areas 93, 94. In these areas 93, 94, the lower covering part 100 has an edge 102 that laterally covers the base body 41, which is also separated into opposing areas 103, 104. These areas are located in the same location as the edge 92 of the covering element 90. This means that the edge 92 of the covering element 90 and the edge 102 of the lower covering part 100 combine to form a visually closed edge that covers the base body in a laterally circumferential manner in the first rotary position of the covering element 90 with respect to the base body 41.

(31) However, due to the separation of the edge 92, 102 it is possible at any time to laterally rotate the covering element 90 with respect to the base body 41 and with respect to the lower covering part 100 at the same level in order to allow access to the fastening screws and passage holes 46. It is not required to lift the covering element 90 in this case. Additional or dedicated spring elements that push the covering element 90 against the base body 41 are no longer required, since the covering element 90 is always held securely and kept rotatable by the flange ring 110.

(32) It is apparent that the covering element 90 and the lower covering part 100 combine to form a kind of housing around the base body 41, which is closed in the first rotary position of the covering element 90 and covers the base body 41 from all sides, but which can at the same time be opened at one level using a simple rotary motion in order to install or remove the base body 41. The covering element 90 acts similarly to a swing top lid for the housing, while the lower covering part 100, which is located between the base body 41 and a window sash (not shown in the figures) when the installation body 40 is in the installed position, constitutes the base of the housing. The edges 92, 102 complement each other in the closed position to form side walls, which cover the base body 41 on the sides. In the opening position, the trailing edges 92 of the covering element 90 form stops for the rotary motion so that the covering element 90 can only be opened and/or twisted to a certain angleas shown in FIG. 6. The lengths of the respective edges 92, 102 on the covering element 90 and the lower covering part 100 are aligned with each other in such a manner that a rotation of the covering element 90 results in an opening angle that is sufficiently large to allow access to the fastening screws or passage holes 46 and that the edge 92, 102 exhibits a visually closed appearance in the first rotary position of the covering element 90.

(33) To prevent the covering element 90 from inadvertently opening and/or twisting during use of the handle 20 by its own rotary motion, the covering element 90 and the lower covering part 100 may be connected with each other in a force-locking, friction-locking, and/or positive-locking manner in the first rotary position of the covering element 90. For this purpose, the corner areas 101 of the edges 102 of the lower covering part 100 are provided with one chicane 108 each, which keep the covering element 90 in that position when it has been moved to its first rotary position. Such a chicane 108 would, for example, be provided as an elevation, which exhibits lightly elevating flanks 109 to act as running surfaces. A rotation of the covering element 90 from the second rotary position to the first rotary position causes the covering element 90 to be slightly raised at the edges, while the elevation 108 is either in friction-locking contact with the covering element 90, or alternatively the covering element 90 may be provided with a corresponding (not shown) element on its bottom side which engages with the elevation 108. The covering element 90 itself acts as a spring element here.

(34) To prevent the lower covering part 100 from getting lost while the actuation element 10 is not fitted to the door or window, the base body 41 and the lower covering part 100 can be interlocked with each other. For this purpose, two mandrels 120 are provided on the lower covering part 100 that clamp into or interlock with the two holes 49 inside the plate 41.

(35) Furthermore, the lower covering part 100 can be provided with circumferential edge sections 122 that surround the base body 41 on the sides and fit the shape of the latter. The width of the edge section 122 is smaller than the width of the edges 102 so that the covering element 90 with its edges 92 can still fully enter the first rotary position. In this rotary position, the edge section 122 is located behind the edges 92 of the covering element 90.

(36) To ensure that the fastening screws are flush with the top side 47 of the base body 41, every passage opening 46 of the base body 41 comprises a countersunk recess 461 to serve as a receptacle for a screw head. In order to provide an anti-twist mechanism for the installation body 40 on a door leaf or window sash, tappet-like protrusions 126 may be provided on the rear side 124 of the lower covering part 100 facing away from the base body 41. It is apparent that the recesses 461 in the plate 41 and the tappet-like protrusions 126 in the lower covering part 100 complement each other.

(37) Preferably, the covering element 90 and the lower covering part 100 are designed to be symmetrically aligned within the base body 41 with respect to the center point of the recess 42. This simplifies the manufacturing of these elements 90, 100, as well as their handling and assembly.
