The lower part is fixable by screws on the door or window frame and the upper part holds the locking cylinder (70). The two parts can lie one above the other in alignment in the detent position to form a closed rosette type body. Detent means are provided between the two parts. At least one part can have a detent nose to engage in corresponding recesses in the other part in the detent position of the rosette.

Description

The invention relates to an operating handle for windows, doors or the like. according to the preamble of claim 1.

Lockable or lockable handles are known. Especially for Rooms that must be secured from the inside have been lockable window or door fittings developed. These usually have an axially fixed rotatable in a stop body mounted handle, in the handle head Lock cylinder is used. The locking cylinder typically has an axially displaceable stored locking bolt, which by pressing a key in a recess provided in the stop body can engage. On Turning the handle relative to the stop body is in this locked position not possible anymore. Another design operates via the axial Stroke of the lock cylinder a coupling element with tooth-like depressions, that engages an identical counterpart in the stop body brought.

Both designs have the disadvantage that the handle neck or the handle respective locking elements must be adapted. Often it is too a change in the handle design required to the lock cylinder or To be able to integrate the coupling element into the handle.

Also known are handles in which a locking member is radial to the axis of rotation of the handle acts. So DE-A1-3 416 151 describes a lockable Window handle with a stop body which can be fixed to a window sash, a cover plate arranged on this front and one in the Stop body with axially fixed, rotatable handle. On the side is a Lock cylinder introduced, in certain functional positions of the window handle with a locking pin that can be moved relative to the axis of rotation of the handle engages radially in a rotationally fixed locking element connected to the handle. The latter has four circumferentially arranged at 90 ° intervals Recesses. Since the lock cylinder housing the drill holes of the Stop body for receiving the fastening screws partially covered, is the assembly of the handle on the window sash only with the locking cylinder removed possible. This can only be used if at least the stopper was attached to the window. One only from the handle held cover plate can also be easily removed, making both the Fastening screws and the locking cylinder are freely accessible. A high security against burglary is therefore not guaranteed. Because of the numerous Individual parts are expensive to manufacture and assemble the conventional window handle and expensive. To noticeably close the functional positions of the window handle make, spring-loaded locking balls are arranged within the stop body, which each snap into the corresponding recesses of the spherical shape can, which is located on the inside of a retaining flange of the locking element located. Another disadvantage is that the locking balls outside their locking recesses pressed with relatively high force against the retaining flange become. This creates frictional forces that cause the handle to twist complicate and result in high material wear.

The invention generally aims at a lockable with simple means To create window handle of inexpensive and robust construction. The aim high security against burglary and a uniform design of the Handle even when using different locking systems. The Window handle should be easy to assemble and easy to use.

Main features of the invention are in the characterizing part of claim 1 specified. Refinements are the subject of claims 2 to 13.

With an operating handle for windows, doors or the like. with a using fastening screws on a window frame, door frame or the like. definable stop body, with a handle, with one in the stop body rotatable about the axis of rotation the locking member mounted on the handle, which is firmly coupled to the handle, and with a locking cylinder integrated in the stop body, which is in the locked position with a locking element which can be moved radially to the axis of rotation of the handle in engages the locking member, the invention provides according to claim 1 that the stop body in a plane perpendicular to the axis of rotation of the handle in two relative to each other pivotable sub-body is divided, with a lower sub-body with the fastening screws fixable on the window or door frame and the locking member is anchored axially fixed in the lower part body and an upper part body the locking cylinder takes up, and wherein the two partial bodies are not pivoted against each other can when the locking element engages in the locking member. With this it is possible the fitting in the fully preassembled state simply and conveniently on the To fasten window or door frames. The arranged inside the stop body Fastening screws are initially not accessible from the outside. By Swiveling the upper part of the body, however, they can be completely exposed and be screwed in according to their function.

According to claim 2, the partial bodies are pivotable about the axis of rotation of the handle and lockable against each other according to claim 3. This simple and at the same time practical design enables a simple and robust Structure of the fitting. By locking the sub-bodies together, a prevents accidental pivoting.

To give the partial bodies a secure hold in the closed position, points out loud Claim 4 at least one of the partial body at least one latch, a survey or the like. which, in the locked position of the rosette body, in corresponding recesses, Depressions or the like engage positively in the other part of the body.

The embodiment of claim 5 provides that the partial body in alignment in the locking position lie on top of each other and form a uniform, closed rosette body. The bisection of the stop body is hardly noticeable. Cover plates or -caps are not required as all internals are absorbed by the part bodies are. The fastening screws are effectively covered by the upper part of the body.

The lower part of the body preferably has a circumferential upstand or edge elevation, while the upper part of the body a circumferential Bending, gradation or draft bevel. The upper part of the body can thus be easily pivoted by lifting against the lower part of the body become.

The further development of claim 7 is important, according to which the partial bodies in Axial direction are spring-loaded. Claim 8 further provides that the upper part of the body is loaded by a compression spring against the lower part of the body is, wherein the compression spring is preferably a coil spring. An accidental Swiveling one of the partial bodies is thus reliably excluded, because the upper part of the body was previously raised against the spring force must become. An unintentional swiveling of the upper part is excluded.

The locking member is expediently a rotationally symmetrical according to claim 9 Body with at least one circumferentially arranged locking recess for Inclusion of the locking element which, in accordance with claim 10, a radial to Axis of rotation of the handle retractable and extendable locking bolt. Thanks to the radial engagement in the locking element, the fitting holds even larger ones Torques stood. As a result, high security against burglary is guaranteed especially since neither the cylinder lock nor the fastening screws accessible by prying off any cover plates or other parts are.

Since the handle neck and the locking member according to claim 11 via a square pin are non-rotatably and axially fixed coupled, the handle extended bolt must not be turned; the fitting is then locked securely.

Important advantages of the invention are that the fitting is locked Condition can not be dismantled because the locking bolt in the locking member engages and therefore not only the handle, but also the upper one Partial body of the stop body is locked in relation to the lower one, whereby the fastening screws are covered.

Further important features of the invention emerge from claim 12, according to which Locking means are provided with at least one locking element, which in at least one functional position of the handle non-positively and / or positively engages in an associated locking recess and when pivoting the Handle from a functional position against a first spring force the locking recess can be disengaged and that each locking element in its locking or functional position of an additional force and outside of it Locked position loaded by a force opposite to the first spring force is less than the first spring force. The force with which the locking element must be triggered from the recess, is thus significantly larger than that Force with which the locking element outside the functional positions of the handle is burdened. To turn the handle from a locked position must have a greater torque compared to conventional locking means be used so that the rest position and thus the functional position of the handle is always clearly noticeable. Outside of the rest position, the Opposing force of the spring force, so that the locking element with only one relatively small resulting force is loaded. This causes sliding friction greatly reduced between the handle and locking elements, as well as by Wear caused by friction. The handle can be done with little Manage effort easily and comfortably.

The actuating handle, generally designated 10 in FIG. 1, is lockable Window fitting trained. It has a stop body 12, by means of fastening screws 22 on a window sash (not shown) can be fastened, a handle rotatably mounted about an axis of rotation D. 50 with a grip head 51 and an adjoining main grip part 53 and a locking cylinder 70 inserted laterally into the stop body 12, the in the locked position of the handle with a locking bolt 72 in a fixed the handle 50 connected locking member 42 engages.

The stop body 12 is in a plane E perpendicular to the axis of rotation D of the Handle 50 divided into two sub-bodies 14, 34, namely a lower sub-body 14 and an upper part body 34, which together form a uniform, form a closed rosette body.

The lower part of the body 14 (FIGS. 2a, 2b) is essentially solid and has on its front 15 facing the upper partial body 34 a peripheral edge elevation 16 on the outside, flush with the side surfaces 17 of the lower part 14 completes. He also has one essentially rectangular flat recess 18, which is centered on the axis of rotation D of the handle 50 in the longitudinal direction L of the partial body 14 or the stop body 12 is aligned. The bottom 19 of the recess 18 has a circular shape Bearing opening 20 with a widening 21 that extends in a step-like manner to the outside on. Above and below the flat recess 18 are for receiving the Fixing screws 22 through holes 23 are provided. This are aligned in the longitudinal direction L on the central axis M of the lower part of the body 14 and are on the front 15 for receiving countersunk screws countersunk. On the back, the lower part carries 14 cams 24, which of the Bores 23 are penetrated.

The upper partial body 34 (FIGS. 3a, 3b) is also essentially solid educated. It closes flat on the front 15 of the lower part of the body 14 and has a step-shaped on its rear side 35 facing Edge 36. The dimensions of the edge step 36 are the circumferential Edge elevation 16 of the lower part 14 is adjusted so that it is form-fitting the level 36 sits on. The side surfaces 37 of the upper partial body 34 are closed its front 39 slightly inclined, but close at the Parting plane E of the partial bodies 14, 34 is flush with the side surfaces 17 of the lower part body 14 from (Fig. 3a, 3b). All outer edges of the upper part 34 and also the lower part 14 can be slightly rounded or chamfered.

Centered on the axis of rotation D of the handle 50, the upper part 34 of the Rosette body 12 a step-shaped round recess 38. It is on the Front 39 of the upper part 34 is designed as a spring seat 40 for the handle 50 and takes in their broader compared to the spring seat 40 Main part 41, the locking member 42 (Fig. 4a, 4b). The latter is a rotationally symmetrical one Body with a central square bore 44 and with over bores 45 distributed around the circumference for receiving the locking bolt 72. Preferably four such bores 45 are circumferentially spaced from 90 ° each available.

As can be seen in FIG. 4 a, the locking member 42 has on its spring seat 40 in the upper part 34 facing away from a neck 46. This is in the bearing opening 20 of the lower rosette part 14 used (Fig. 1), while the Axle body or the locking member 42 itself on a shoulder of a locking means 80 supports that inserted into the flat recess 18 of the lower body 14 is. The locking member 42 is axially fixed-rotatable in the lower rosette part 14 stored, one inserted from behind into the step-shaped widening 21 Washer 47 and a in a circumferential groove 48 in the neck 46th snap ring 49 serve for securing.

The handle 50 penetrates with a handle head 51 that continues on the end face Handle neck 54 the spring seat 40 of the upper rosette part 34, the Handle neck 54 with its end face 55 on the in the recess 38, 41 of the Rosette top 34 rotatably mounted axle body 42 is placed flat. The End face 55 of the handle neck 54 receives a square pin 56, which by the Square bore 44 of the axle body 42 with its free end 57 in a gear (not shown) integrated in the window frame engages. The Handle 50 and the axle body or the locking member 42 are thus over the Square pin 56 locked against rotation and axially fixed to each other, so that a Rotary movement of the handle 50 is transmitted directly to the axle body 42 and pulling out of the handle 50 is prevented.

A compression spring 59 is preferably on the handle neck 54 of the handle 50 a coil spring attached. It is supported in a handle neck 54 surrounding circumferential recess 60 in the handle head 51 and in the spring seat 40 of the rosette top 34. As a result, the rosette top 34 of the Spring force pressed onto the lower rosette part 14. The edge elevation 16 and the Edge step 36 of the rosette body 12 are engaged, whereby the Partial bodies 14, 34 are fixed to one another in a fixed position.

In Fig. 1 it can be seen that between the lower edge 52 of the handle head 51st and the rosette top 34 there is a distance K, which is conveniently something is greater than the height H of the edge elevation 16 of the lower rosette part 14 or the edge step 36 of the lower part 34 of the rosette against the spring force of the compression spring 59, it slides on the axle body 42 in the recess 38, 41 upwards until the upper part 34 on the Handle head 51 abuts. The back 35 of the upper part 34 lifts from the front 15 of the lower part 14, with the edge elevation 16 of the lower part 14 the edge step 36 of the upper part 34 comes out of engagement. The upper part 34 leaves now around the locking member 42 and thus about the axis of rotation D of the handle 50 pivot until both bodies 14, 34 an angle of z. B. Include 90 °. The fastening screws 22 in the lower part of the body 14 are now free and are easily accessible. The rosette body 12 can easily and can be easily mounted on the window sash without having to dismantle parts beforehand or would have to be installed afterwards. The fully pre-assembled Actuating handle 10 can quickly and without an auxiliary tool on one Window frames are attached.

For receiving the locking cylinder 70 is on a narrow side of the rosette upper part 34 a receiving bore 73 is present, which is substantially parallel to the central axis M of the upper part 34 or the stop body 12 and radially to Axis of rotation D of the handle 50 extends and on an intermediate wall 74 in the rosette upper part 34 ends, in the center of the receiving bore 73, a through opening 75 is present. The height of this opening 75 and the height and position of the bores 45 in the axle body 42 are assigned to one another in such a way that in each functional position of the handle 50 or the operating handle 10 an associated bore 45 congruent over the Through opening 75 comes to rest.

The locking cylinder 70 has a housing 71 in a form-fitting manner in the receiving bore 73 pressed in (Fig. 1). He has one by means of a key 76 Locking bolt 72 can be extended and retracted linearly to the cylinder axis the handle 50 in a desired functional position, the operating handle 10 can be locked by pressing the key 76. The Locking bolt 72 is extended along the cylinder axis and engages the opening 75 into that assigned to the respective functional position Bore 45 in the axle body 42. This is rotatably connected to the handle 50 and, as a locking member, prevents the handle 50 from rotating. The window is locked. Since the lock cylinder 70 and thus the locking bolt 72 are accommodated in the upper partial body 34 and the locking member 42 is anchored axially fixed in the lower body 14, the locking bolt prevents 72 also a lifting of the upper part 34 from the lower part 14. Both partial bodies 14, 34 can therefore not be pivoted against each other and it is not possible to reach the mounting screws 22. If you drive the Lock bolt 72 with the help of the key 76, so he gives the axle body 42nd free and the handle 50 can be pivoted into the desired position, the rosette bodies 14, 34 twist against each other if necessary leave (for example for assembly purposes).

The back 35 and the front 15 are of suitable construction Measures (e.g. flattening, draft bevels) designed so that without Lifting off the upper part 34 and turning it back from the 90 ° position into the 0 ° position is made possible.

As already mentioned, in the flat recess 18 of the lower part of the body 14 a locking means 80 is used (FIG. 1), which has a rectangular frame 82 rounded corners 84 and straight longitudinal or transverse sides 86, 88 and two locking elements 90, which resiliently mounted on spring bars 92 are and engage in associated locking recesses 132 of the axle body 42 can (Fig. 4a, 4b). Four detent recesses 132 are preferably circumferential arranged at a distance of 90 °. They are immediately below the Bores 45, so that the locking elements 90 in each functional position of the Snap the handle 50 into the recesses 132. The latter have a semicircular Cross-section and their height corresponds to the height of the locking elements 90.

The spring bars 92 are arranged opposite one another within the frame 82 and convexly curved along the transverse sides 88 of the frame 82 (FIG. 5a, 5c). They are supported with their outer ends 94 in the corners 84 of the Transverse sides 88 of the frame 82 and bear on their facing each other A protrusion 96 in the center of each side for receiving the latching elements 90. These can be designed as locking pins and upright in blind holes 98 Spring bars 92 may be used so that they are part of their circumference protrude the protrusions 96. 5a that the locking pins 90 aligned with the longitudinal axis L and symmetrical to the transverse axis Q of the frame 12 or the stop body 12 are aligned. So you can at the same time and evenly in the assigned locking recesses 132 in Snap axle body 42 into place.

Each projection 96 of the spring bars 92 sits laterally with two bar arms 103, the ends 104 facing each other on the projection 96 and with ends 106 facing away from one another on the longitudinal sides 86 of the Frame 82 are set. The web arms 103 can be straight and run symmetrically to the longitudinal axis L of the frame 82. The facing each other Ends 104 of the bridge arms 103 set at the height of the central axes 91 of the locking pins 90, while those on the longitudinal sides 86 of the frame 82 fixed ends 106 of the web arms 103 by a distance A relative to the central axis 91 of the locking pins 90 are set back. The web arms preferably form 103 together a second spring bar 102, which is within the frame 82 runs essentially parallel to the spring bars 92 and overall Is arranged in a V-shape. Both web halves 103 close to the central axis 91 of the locking pins 90 an obtuse angle. The ends 104, 106 the web arms 103 can each be tapered (FIG. 5d).

Between the web arms 103, the frame 82 is of a flat plate 110 spans, which attaches to the upper edges 87 of the long sides 86 and with their side edges 112 the contours of the web arms 103 and the attached Projections 96 follows. The latter are therefore just like the outer ones Spring bars 92 and the web arms 103, below a recess 116 in Frame 82; they can be resilient in the longitudinal direction L of the stop body 12 be moved. At the intersection of the longitudinal and transverse axes L, Q of the frame 82, the plate 110 has a round recess 113 with a neck extension 114 on.

The frame 82, the spring bars 92, 102 with the projections 96 and the Plate 110 are preferably made in one piece from an elastic plastic. The locking means 80 can thus be easily and inexpensively as an injection molded part manufacture and together with those in the projections 96 of the spring bars 92, 102 inserted, preferably made of metal locking pins 90 in the insert lower part of body 14. The flat recess 18 takes the frame 82 positively so that the intersection of the longitudinal and transverse directions L, Q of the frame 82 lies in the axis of rotation D of the handle. Because the frame 82 extends with its longitudinal axis L in the longitudinal direction of the stop body 12, the locking elements 90 are also symmetrical on both sides of the Axis of rotation D of the handle 50 and thus on both sides of the axle body 42. The spring bars 92, 102 are supported by the frame 82 on the partial body 14 from, so that a good power transmission is always guaranteed. Because the Detent elements 90 sit on both sides of the axis of rotation D, the locking member 42 equally loaded from two sides.

Are each in the functional positions of the handle or the axle body 42 two opposite locking recesses 132 on the longitudinal axis L des Stop body 12. The flattened locking pins 90 engage positively in the opposite recesses 132 of the axle body 42. The diameter of the axle body 42 and the dimensions of the frame 82 and the Spring bars 92, 102 are dimensioned such that the latter in the locking position below with a slight bias. As a result, both the outer, curved spring bars 92 as well as the V arms 103 a force F1 or F2 on the locking elements 90, which due to the symmetrical arrangement of the bridge arms 103 act in parallel.

If you turn the handle 50, the locking pins 90 slide out of the locking recesses 132 out. They are now between the individual functional positions with its full diameter on the smooth peripheral edge 131 of the Axle body on, the side attaching to the locking pin receptacles 96 Web arms 103 are compressed against the longitudinal sides 86 of the frame 82. In addition, the locking pins 90 get behind the attachment points 106 of the bridge arms 103 on the frame 82, whereby the spring bars 102 in the direction of the transverse sides Q of frame 82 fold down. The tapered ends 104, 106 of the Bridge arms 103 act as joints and facilitate the process. By the folding or upsetting must be in addition to the spring force F1 by the outer spring bars 92 is generated, an additional spring force F2 is applied to twist the handle 50.

Since the starting points of the outer ends 106 of the web arms 103 on the frame 82 are selected such that the locking pins 90 when turning the handle 50th are moved beyond the starting points of the web ends 106, the Spring bars 103 in their folded positions a counterforce G on the Locking elements 90, which counteracts the force F1 of the outer spring webs 92. The locking pins 90 are then only with a differential force F1-G pressed against the peripheral edge 131 of the axle body 42, so that the Handle 50 can be easily turned. When the locking pins 90 into the recesses 132nd of the axle body 42, the web arms 103 of the inner spring bars fold 102 back to their starting position and put the handle 50 together with the outer spring bars 92 in the functional position that the selected rest position is assigned.

The frame 82 gives the locking means 80 the necessary internal mechanical Stability and transfers the spring forces F1, F2, G of the webs 92, 102 the stop housing 14, 34, which is fixed to a window or door leaf is appropriate. It can be seen that the spring bars 92, 102 as double bars are formed, the from the axis of rotation D of the handle 50 seen outer web 92 has a curved shape and the inner web 102 from consists of two straight web halves 103, the V-shaped and their Ends 104, 106 are thinner than the middle part of the web halves 103. For the Recording the locking pins 90, a cage 96 is provided, which is also the Connects with each other in the middle of the inner and the outer web 104 or 106. It therefore forms a coupling member for the spring bars 92, 102, which thus act as a double bar Act.

Both spring bars 92, 102 generate in the direction of the axis of rotation D of Handle 50 or on the axle body 42 together a total force F1 + F2, whereby due to the web arrangement in the locking positions only the force F1 of the outer webs 92 is actively exercised. The force of the inner webs 102 is only when the handle 50 is unscrewed from one of the functional positions activated. In an excellent position of the handle 50, the Locking pins 90 in two opposite locking recesses 132. If you turn that Locking member 42 by means of the handle 50 from its locking position, so the Locking pins 90 counter to the force F1 + F2 of the two double webs 92, 102 the recesses 132 out. So you have to apply an increased torque the axle body 42 or on the handle 50 to prevent twisting cause. The functional positions can be felt clearly and precisely while the effort to turn the handle is minimal, however with the rotation of the locking disc 130 between the excellent Positions there is no movement of the alignment pins 90. It is consequently not to perform mechanical work against the spring force of the double web 92, 102. Rather, only a torque has to be applied in order to however, due to the web arrangement significantly reduced - frictional force to overcome that arises between the locking pins 90 and the axle body 42.

The ends 104 of the web arms 103 connected to the receiving cages 96 are in an excellent position of the axle body 42 closer to the Axis of rotation D of the handle 50 than that on the long sides 86 of the frame 82 connected web ends 106. As a result, the web arms 103 generate them Positions each have a force F2 parallel to the forces F1 of the outer spring bars 92 and thus increase what is required to disengage the dowel pins 90 Torque.

The dowel pins are outside the excellent positions of the axle body 42 90 and thus the two attacking the receptacles 96 of the locking pins 90 Ends 104 of the web halves 103 further away from the axis of rotation D than the web ends 106 attached to the peripheral frame 82. Due to the Length of the web arms 103 fold them backwards, the thinner ones trained ends 104, 106 of the web arms 103 act as joints. The Folding down the web halves 103 has the effect of a toggle lever, whereby the Stegarme 103 outside the excellent positions each a force G Generate antiparallel to the forces F1 of the outer spring bars 92. this has with the result that the resulting differential forces F1-G of the double webs 92, 102 to the locking pins 90 and thus significantly reduced to the axle body 42 are. As a result, the frictional forces between the locking pins 90 and the axle body 42 are considerably smaller, so that to continue turning the Handle 50 torque is noticeably lower.

The invention is not restricted to one of the above-described embodiments, but can be modified in many ways. Instead of the edge elevation 16, the lower part of the body 14 with the fastening screws 22 arranged flat recesses are provided in engage the corresponding flat elevations of the upper part 34. Depending on Height of the rosette body 12, it may be appropriate to the receiving hole 73 for the lock cylinder 70 and the blind bores 45 for the Lock bolt 72 to be arranged slightly obliquely, so that in the lock cylinder 70th inserted keys 76 obliquely upwards away from the casement points out what makes handling easier. The locking elements 90 can be used as Plastic noses and with the spring bars 92 and the bar arms 103 be in one piece. Also angular or oval cross sections of the locking lugs 90 or the locking recesses 132 are possible. If the spring bars 92 are replaced by coil springs or leaf springs, there are further advantageous Refinements of the locking means 80, which can be done by simply adjusting the recess 18 and frame 82 in a wide variety of stop bodies 12 can be used. The frame 82 is always positively supported in the recess 18 from; it can also be shaped approximately square or oval. At a Simplified embodiment are those acting on the locking elements 90 Forces applied exclusively by the spring bars 102.

Important advantages of the invention result from the fact that the locking element 90 when pivoting the handle from the functional position against one First spring force F1 directed perpendicular to the axis of rotation D of the handle can be disengaged from the locking recess 132. The or each locking element 90 is in the rest position of an additional force F2 and outside of its rest position loaded by a force G opposite to the first spring force F1. The additional force F2 and the counterforce G are from V-shaped spring bars 102 generated, which on the locking elements 90 symmetrically with web arms 103 attack. These are supported with their mutually facing ends 104 on the locking element 90 and with their ends 106 facing away from each other the stop body. To generate the first spring force F1 are convex Arched spring bars 92 are provided, which together with the bars 102 Form a double web and carry the locking elements 90 in the middle. The latter are preferred formed as locking pins and held in suitable holders 96.
