Definitions

• the invention relates to an operating handle according to the preamble of claim 1.
• DE-U-8 209 449 discloses a handle of this type, namely a lockable window handle.
• a profile cylinder inserted into the handle head itself forms the actuating element for locking the handle by means of a locking pin which engages in a stop plate or its cover.
• a comparable arrangement is shown in DE-U-8 228 856, namely also a lockable turning handle which is mounted on a rosette and into which a profile cylinder is inserted.
• the design should allow the dimensions of the rotary handle to be determined only by the size of the profile cylinder. However, this applies at most to the width dimensions, not to the overall height.
• the lock bit of the profile cylinder should also allow one of two legs of different lengths Push the U-shaped locking spring to the side, which holds the cylinder in place and secures the active position of a locking pin.
• the common designs have in common that they require a relatively large overall height to accommodate a movable lock.
• a (standardized) profile half cylinder is usually used as such. Its dimensions generally require a certain degree of irregularity, and in addition the overall height causes the handle body, which is usually flush with the handle head, to be at a greater distance from the stop plane (or the window frame) than non-lockable twist handles otherwise require.
• the chunkier construction of the latter is disadvantageously noticeable. Larger handle neck lengths also have the consequence that greater tilting moments are exerted during handling.
• the object of the invention is generally to overcome the disadvantages of the prior art using means which are equally economical to manufacture and assemble.
• a more specific goal is to improve a turning handle of the type mentioned in such a way that the main part of the handle moves closer to the stop plane and thus allows another turning handle of the same kind.
• Lean shapes should be possible as well as reliable locking.
• the invention provides that the handle head is inclined with respect to the axis of rotation, preferably at an acute angle.
• the lock is therefore not actuated parallel to the axis of rotation.
• a conventional profile cylinder which can preferably be used is arranged obliquely in a space-saving manner, as a result of which the overall height of the handle is considerable is reduced and the overall safety is increased, because due to the main grip part closer to the stop plate, the maximum possible tilting moment is also noticeably smaller than before.
• the square hole bushing is integral with a hat plate fastened in the lower part of the handle head, which has a receptacle inclined at an acute angle to the axis of rotation of the handle, into which a Locking element can be moved by a lock.
• the inclined at an acute angle to the axis of rotation ensures secure engagement of the lock member operable with the lock, which is just as easy to disengage.
• the design is characterized by a small footprint and, above all, allows very slim, pleasing designs.
• the handle head can have such a profile recess that the lock is vertically displaceable and lockable at the same angle of inclination to the axis of rotation.
• a different angle of inclination could also be selected, for example in order to provide a different hand position when touching or a somewhat different direction of actuation in order to adapt to spatial conditions.
• the flush surface is advantageous according to claim 3, which not only contributes to a pleasant appearance of the handle, but also to cheap handling with an essentially smooth thumb rest.
• the main handle part according to claim 4 can connect to the handle head with an elegant shape, namely at a significantly reduced distance from the stop or window frame surface compared to the prior art.
• claims 5 to 7 relate to means for fixing and unlocking the lock in the handle head, which for this purpose contains in particular a very simple leg spring which is as robust as it is reliable.
• the locking member is a slide with two oblique pressure ends, which come into contact with the lock inside the top plate at the top of the striker and therefore keep it pressed against spring force. It can be seen that when the handle is closed, no rotation or pivoting of the main body part is possible because the e.g. trained as a claw coupling locking device does not allow this.
• an adjusting screw can be arranged between the collar and the underside of the lock, preferably with an anti-loosening device.
• the setting is made so that the outer surface of the lock is flush with the top surface of the handle head.
• a fine adjustment can be made without play.
• the striker according to claim 15 is slidable within the top plate on a spacer ring, which supports the axially fixed-rotatable mounting of the handle and increases the effective bearing length.
• the striker can be a rotationally symmetrical claw ring, which further contributes to reducing the dimensions.
• the design according to claim 17 promotes the rapid engagement of the locking member, since the receptacle can be guided in particular on the underside up to the height of the axis of rotation, whereby any risk of canting is excluded.
• a window handle generally designated 10
• a window handle which has a handle main part 12 and a handle head 14.
• the top surface 16 of the grip head 14 merges at an obtuse angle into the grip main part 12, which has finger depressions on its underside.
• the innermost one has a smoothly curved transition to the rear side 18 of the handle head 14.
• a bushing 22 which is integral with a top plate 24 which is fixed, for example, by means of a screw flange 26 in the grip head 14 from below (see FIGS. 3 and 5a to 6c).
• the socket 22 has a square hole 28 for receiving a square 88 with which the mechanism of the window mechanism can be actuated.
• the handle 10 With the socket 22, the handle 10 is fixed to a stop plate 40 which can be screwed onto the stop surface, namely a window frame, by means of cams 42.
• the screw connection is covered by a cover plate 48 which can be pivoted to the side against the force of a support spring 50 so that the screws (not shown) are accessible.
• the stop plate 40 is in one piece with a bearing bush 44 which receives guide elements for the insert part 22/24.
• This includes a flange ring 32, to which a spacer ring 36 connects, and a sleeve 46, which can be made in one piece with a counter-locking ring 54, which cooperates with a bottom locking ring 52.
• the locking ring arrangement can be designed, for example, in the manner of DE-GM 83 31 873 or 84 06 230 and has in particular the purpose of specifying predetermined angular positions for the handle 10, which are customary and standardized for window operation.
• a profile recess 56 is provided, which receives a profile cylinder lock 60.
• This has a lock bit 62 with which a leaf spring 90 (see FIGS. 8a to 8c and 10, 10b) serving to lock the handle 10 can be unlocked so that the handle 10 and thus the window can be operated.
• the locking cylinder 60 is displaceable in height below an upper limit position (see FIGS. 5a, 10a). If you press the profile cylinder 60 so that its top is flush with the top surface 16 of the handle head 14 (see. Fig. 1, 5b, 10b), a locking spring 64 engages, which is inserted from below into the handle head 14 and is held therein by fastening the top plate 24.
• the generally U-shaped, one-piece spiral spring 64 can be made of plastic and carry latching projections 68 on legs 66 which are bent back inward and which can laterally fall into the openings of a threaded hole 86 present on the profile cylinder 60 (FIG. 5b).
• the handle head 14 has near its rear 18 at the bottom an opening 100 through which one can engage with an auxiliary tool (not shown) in order to spread the spring legs 66 so that the projections 68 disengage and the (unlocked) profile cylinder 60 can be removed.
• the locked lock cylinder 60 can be moved up to the inner shoulders 59 when the lock bit 62 presses one leg 96 of the leaf spring 90 to the side, that is to say unlocks it.
• the spring 90 has a holding leg 92 fastened on the top plate 24 with a square hole 98 and also an angle 94, as a result of which its abutment in the profile recess 56 is defined (see FIGS. 4 and 8a to 8c).
• the lock bit 62 releases the spring leg 96 so that it springs into the interior of a transverse opening 61 present in the cylinder 60, as can be seen in FIG. 4, as a result of which the cylinder 60 is locked. Its upward movement is limited by the abutment of bending folds 65 of the spring 64 on inner edges 15 in the grip head 14 (cf. FIGS. 5a and 5b).
• a locking member 70 designed as a slide is slidably arranged in the grip head 14 together with the latter.
• the locking slide 70 is designed as a partial annular disk and is provided with a collar 72 which projects downwards and which is surrounded by a compression spring 74 which is supported on the top of the top plate 24.
• the slide 70 On the circumference, the slide 70 carries two legs 76 projecting downwards with oblique pressure ends 78. These engage in a likewise obliquely arranged receptacle 30 of the top plate 24 and arrive the top of a striker 38 for contact, which is arranged on the spacer ring 36 parallel to the axis of rotation A in height.
• Essential for the function of the handle according to the invention is the inclination of the handle head 14 by an angle of e.g. 30 ° to the axis of rotation A (Fig. 1).
• the correspondingly oblique arrangement of the displaceable profile cylinder 60 enables the desired locking functions in that the top plate 24 has a correspondingly inclined receptacle 30 and a bevel 34, as can be seen particularly from FIGS. 6a to 6c.
• a projection 84 is provided, on which the holding leg 92 of the leaf spring 90 with the square hole 98 is placed and riveted.
• a likewise obliquely arranged recess 83 can support the collar 72 of the locking slide 70 in its lowest position.
• the compression spring 74 finds its abutment on the outer circumference of the depression 83.
• FIGS. 9a and 9b An adjusting screw 80 which can be screwed into the threaded hole of the collar 72 to compensate for dimensions is shown in FIGS. 9a and 9b. It can be provided with an anti-loosening device 82 and enables the tolerances or differences in the lock cylinder lengths to be compensated for sensitively.
