Abstract

The invention relates to a handle (10) which is mounted on a stop body (20) in an axially fixed rotational manner. Said handle has a polygon (30) which is torsionally rigid in a handle neck (12) which is provided for actuating a closing mechanism. Two driving elements (15, 35) which can move in relation to one another can be coupled directly or by means of coupling elements (36, 40, 42) with positive or non-positive fit between adjacent surfaces (17, 37). Said driving elements are coupled in such a way that a transmission of torque from the handle (10) to the polygon (30) can be effected, whereas said transmission can be blocked from the polygon to the handle (10) by displacing at least one coupling element (36) in the direction of the application of force. A main part of a polygonal driving element (35) can be concentrically enclosed by the handle driving element (15) having fins (52) which comprise push surfaces (19) and which are situated on two shells. Said fins drive, e.g. spring-loaded roll pins (36) which are arranged in pairs and which are retained in a wedge-shaped delimited zone (55). Angular areas of indentations (31) of the polygonal driving element (35) act upon the roll pins (36). Middle parts (50) of the handle driving element (15) can guide a pressure spring (38) which outwardly applies force to locking balls (47) to which recesses (27) of the stop body (20) that are arranged at the edge delimitation (24;44) are allocated.

Description

WINDOW AND / OR DOOR HARDWARE Description The invention relates to a window and / or door fitting according to the preamble of claim 1 and according to claim 24. The fittings in the form of handles for opening and closing elements for closing spaces, ie windows and doors , have frequently been shaped as rotating handles which are fixed with stop elements, such as lock shields, slabs or the like, to a window frame or to a door leaf to actuate a corresponding locking mechanism by means of a driven driving pin. on the handle, p. ex. , a square. In order to prevent this from being carried out by unauthorized persons, various security devices have been developed, such as the push button locks and the so-called safeguards against children opening, among others. DE 295 18 723 Ul describes, for example, a fitting with a pin located outside the handle. This is to run to the side to be able to exert an axial force on the neck of the handle, suspended by the spring, which can be coupled in this way with a stop sleeve that drives the square; Only after the gum can the handle be turned. In other constructions the handles can be fixed in the selected positions, p. ex. , in positions of 90 °, To unlock the rotary movement of a handle locked in this way, you must first activate a subordinate organ. But if a handle is not initially in a given angular position, then an interlock can not be made and the handle can be moved, even by actuating it from the outside. This is based on theft protection methods. In the case of the pivoting tilting window fittings with a gear that allows the change of the rotary drive to a linear movement of the sliding rod, the interlocking can be unlocked when drilling the window profile from the outside and running the rod with a tool introduced through the created hole. A window can also be opened, if the frame is drilled from the outside at the height of the square through which a tool can then be passed. In both cases you can rotate the square and therefore unlock the hardware - You tried to find a solution with the window handles so widespread that they can be closed and can not be moved when locked * In this case, the user has always make sure to close the handle. For this, a key is usually needed that can not be available to third parties; the difficult access to the key is annoying, however, for the authorized person, of m was that it often does not close the window for reasons of convenience- The common disadvantages of known devices are also that the window handles are subject to certain limitations related to the design, if one wants to equip them with the security elements, p. ex. , of the type mentioned.

The users are also really forced to operate the corresponding elements, and precisely in a direction different in a certain way to the usual way of driving. It is an important objective of the invention to overcome this and certain disadvantages of the current level of technology and create an improved handle that offers considerable resistance to operations carried out from the outside, but that can be operated inside the room without any problem . In addition to a clear structure, we aspire to achieve economic manufacturing and assembly. With economic means, greater freedom should also be obtained with respect to the design, mode of use and / or developments of the movement. This objective is solved by means of a window and / or door fitting for the actuation of a closing mechanism with a handle at least in the form of a majnivela which, by means of a handle neck, is housed in a rotational and axially fixed manner on or in a topé body. which can be fixed to a flat support, particularly to an element for closing a space, such as the door leaf, the window frame or the like, and with a multiple edge, which fits into the stop body or which is contained in 41, and which is joined with the handle in a rotationally resistant manner for actuation of a closing mechanism, provided, according to the invention according to claim 1, a coupling structure between the handle and the multiple edge, with which the moment can be transmitted of turning from the handle to the multiple edge, but that can be blocked, on the contrary, from the multiple edge to the handle. A rotary handle is then available in the form of a mechanical diode which, according to the direction of the drive, allows the hand lever to move or prevent it in the opposite direction. Thus, a considerable increase in security can be obtained in a very simple way. The cost of construction is generally low, so that the structure composed of few components can be manufactured and installed without problems. Another embodiment of the invention is based on a handle in the form of a handle, with a handle drag stop, formed as a pin and linearly driven within an edge boundary of a flat support, e.g. e. a box, a stop body or a groove of the socket of a flat support -particularly an element for the closing of a space such as the door leaf, the window frame or the like, with a relatively movable propeller drive stop limited manner with respect to the handle stop, which has an actuating element disposed transversely with respect to the housing or the stop body and connected to the handle for actuating a closing mechanism, and with a coupling structure, located between the handle stop of the handle and the actuating element, which has a coupling piece between the sliding surfaces of the handle stopper and through which the movement of the handle can be unblocked or blocked. handle, regardless of whether a force is exerted on the handle or the drive element. In this connection, it is provided according to the invention according to claim 24 that the coupling part is arranged as a retaining pin and, depending on the position of the handle stop, can be slid into the edge limit. { unlock position] or enter a locking slot [lock position]. It is recognized that this constructive form is not limited to a rotary movement, but that it generally uses displaceable elements and, in particular, linearly movable elements which are joined by a robust coupling piece which acts simultaneously as a blocking element. Precisely from the document DE-A1-35 20 861 a similar principle is known. However, this descriptive report refers to a retraction block in connecting rod fittings that can be operated from a lock by a connecting rod gear. Here, a leaf spring, fixed invariably in a section of the connecting rod, or to a blocking position or moved out of it, is moved, and the locking is based exclusively on the locking of one end of the spring in a narrow blocking projection which can to be closed and / or overcome when bending the spring, which is not very resistant in principle, in case a great force is exerted on a bolt. On the contrary, the new coupling structure has a locking bolt which is movably fixed between the driving stops, but which is not rigidly placed on a drag stop and which also forms a blocking element with its own body. , which can be displaced laterally with a sliding / rolling movement and acts through self-locking similar to a key. Even large drive forces can not overcome this blockage due to the compactness of the retaining bolt. Advantageous configurations are the subject of claims 2 to 23, as well as 25 to 27. Claim 28 refers to the use of the fitting according to the invention in a space closure element.

Other characteristics, features and advantages of the invention are apparent from the text of the claims, as well as from the following description of embodiments with the help of the drawings. They show: Fig. 1 a bottom view of the stop body of a tool, Fig. 2 a bottom view comparable in another embodiment, Fig. 3 a bottom view of another embodiment, Fig. 4 a cross-sectional view, partially in cutting, from a rotating handle, fig, 5a, 5b a cross-sectional view respectively of the components of the window handle of figure 5 in a top and bottom view, (Follow the original memory to partxr on page 4.}.

Fig. 6a to 6c a bottom view respectively of another embodiment, and precisely in the inactive state, as well as in two different operating states, Fig. 7a to 7c a bottom view respectively of another embodiment of a fitting in the state inactive, as well as in two different states of operation, Fig. 8 a separate representation of an adjustment notch in the stop body, Fig. 9 a developed representation of the inner circumference of the adjusting recess of Fig. 8, Fig. 10a to 10b are a cross-sectional view, respectively, of the components of the window handle of FIGS. 7a to 7c and FIG. 11a to a diagrammatic side view of a slide mechanism for handles.

In FIG. 1, the lower part of a stop body 20 is recognized, which can be joined by projections 23 drilled with a surface (not shown) of the window or the door. In the center there is a square 30 that can be turned by the same axis as a handle (not drawn here), fixedly attached to the torsion with a drag stop 15 of the handle. The square 30 is connected in a torsion-resistant manner to a square drive stop 35, the main part of which is concentrically surrounded by the driving stop 15 of the handle. The drag stop 15 of the handle and the square drive stop 35 are components of the coupling structure K, with which the torque can be transmitted from the handle to the multiple edge 30, but which can be blocked by the opposite from the multiple edge 30 to the handle. The square trailing stop 35 comes with a shoulder 33 to an inner wall 44 of a cylindrical recess 24 in the bottom of the stop body 20. A leaf spring 40 meets its main part on the inner wall 44 and surrounds the trailing stop 15 on the handle. At a small distance predetermined with respect to its ends, which form the bearing surfaces 17, the spring 40 is provided with angular ends 42, adapted to the shape of the shoulder 33 of the square driving stop 35 and arranged in the inactive position drawn between the support surface 17 of the handle stop 15 of the handle and a support surface 37 of the square drive stop 35. If the handle is rotated together with the handle stop 15 of the handle, a support surface 17 encounters a end 42 of the dock. This is dragged a bit in this way, thus decreasing the diameter of the spring. The previously adjusted spring 40 can be slightly spaced along the inner wall 44. If the handle stop 15 of the handle is still rotated, the end 42 of the aforesaid spring slides on the abutment surface 37 of the abutment stop. square drive 35, through which the square rotary movement is transmitted through the shoulder 33 and the driving stop 35. The leaf spring 40 serves both as a coupling part, ie, engages with the stopper drag 15 of the handle and the drag stop 35 of the multiple edge so that a turning moment, which acts on the handle, is transmitted to the multiple edge 30 and, as long as the bearing surface 17 slides the end 42 of the dock in question and with it, the trailing stop 35 of the multiple edge. The handle can be turned freely. However, if a square turning moment 30 first arrives, a supporting surface 37 of the driving shoulder 33 rests on the corresponding angular end 42 of the spring 40. The latter extends its diameter, and precisely in the case of the minimum thrust of the corresponding end 42 of the spring. As a result of this, the spring 40 is stuck in the inner wall 44, causing the immediate and total stop of the turning movement. it is recognized that the handle stop 15 of the handle, the spring 40 and the square drive stop 35 are formed and arranged symmetrically with respect to the longitudinal center L of the stop body 20, so as to guarantee the functional independence of the direction of travel. turn. It is also important to set a preset angle of rotation B between the two driving stops 15 and 35, which is fixed by the separations between the bearing surfaces 17 and 37, which must be greater than the thickness of the element 42 of pier located between them. Thanks to this measurement, a driving stop (in the frame of the rotation angle set B) can be rotated without the turning movement being transmitted to the other driving stop, but an effect is produced on the spring 40 or the driving element. coupling This is jammed by a friction closure - starting from the inactive position drawn - in a direction and separates respectively in the opposite direction. In Figure 2 another embodiment of a self-locking mechanism for a rotary handle is observed. Again, the two traversing stops 35 and 15 of the coupling structure K have been rotatably housed around the concentric axis with respect to the square pin 30. In the circumferential direction between the two are coupling pieces 36 in the form of two pairs of coupling elements formed, for example, as rolling pins, which are respectively pressed by a pressure spring 38. The drag stop 15 of the handle d? two leaves have on each leaf a center piece 50 with wings 52 in the form of an arc, the peripheral ends of which have or form sliding surfaces 19. The driving stops 15, 35 furthermore have engagement elements, which are formed as an outlet 51 and a corresponding cutout 56 and arranged with one another with a set B of rotation angle so that in the inactive state shown, the bearing surfaces 17 or 37 separated one from another. The springs 38 between the rolling pins 36 or the cylindrical rollers are guided along webs 46, which extend along the inner wall 44 of the adjustment recess 24. The webs 46, arranged symmetrically between the front surfaces 19 of the wing 52, in the form of an arc, of the stop d? the handle 15, prevent the springs 38 from rubbing during the external turning movement, that is, in the adjustment recess 24 or the inner wall 44; this contributes to the softness of the window handle. As shown in FIG. 2, the configurations? And the driving stops 15, 35 allow the mutual transmission of turning movements without the collection elements located between them. In combined action with the wedge surfaces 39 in the square drive stop 35, the set of rotation angle S between the surfaces 17, 37 determines the function explained below. The coupling parts 36 are in an intermediate space 55 are a slightly trapezoidal shape which is limited by the cylindrical inner wall 44, the sliding surfaces 19, as well as the wedge surface 39 and is extended to the quay 38. The latter causes each roller pin 36 of each pair to be pressed as much as possible into that wedge-shaped intermediate space 55.

If the handle is moved and thus the drag stop 15 of the handle, this is possible until the gap between the bearing surfaces 17, 37 is exceeded without first transmitting a turning movement to the square drive stop 35- The surface 19 of sliding of the arc-shaped wing 52 presses much more against the force of the spring 38 on the pin 36 for contiguous rolling and pulls it tangentially with respect to the surface 44 of the ring of the intermediate space 55 in the form of a wedge. The coupling part 36 can be moved freely in the expandable 2: ona 55. immediately afterwards there are the bearing surfaces 17 and 37 of the two driving stops 15 or 35, which are relatively rotatable relative to one another, through which the further movement of rotation of the outer driving stop 15 to the driving stop is completely transmitted. inside. The rolling rod 36 at the opposite end of the spring 38 is likewise pulled out of the wedge-shaped intermediate space 55 by the friction which originates in the case of the turning movement in the inner wall 44. Thus both can move freely. coupling parts 36. The turning of the window handle is transmitted smoothly to the square pin 30. If, on the other hand, a turning moment engages first or only on the inner driving stop 35, its wedge surface 39 acts on the pin. corresponding 36 rolling. The force acting on it has a very small tangential component and a very large one due to the geometric characteristics.

Accordingly, the rolling pin 36 is pressed with great force vertically against the inner wall 44, thus causing the strong friction arising to impede a turning movement. it is recognized that a direct or indirect rotation of the square pin 30 causes, after exceeding the rotation angle set B, a tightening of the or each collection piece 36 and in this way immediately stops further movement. It may be advantageous to cover the inner limit 24/44 with a material more flexible than the materials of the square drive stop 35 and the coupling piece 36. In this way, the driven roller pin 36 can be depressed in the inner wall 44 when the inner drive stop 35 is rotated, whereby a positive connection is obtained which allows a high load of the torque in the square drive stop 35. Figure 3 shows another example of embodiment similar to that of Figure 2, but with a simplified construction. Here there is only one pair 36 of laterally disposed bearing pins which is loaded by the pressure spring 38 and which always remains, in the case of the turning of the handle stop 15 of the handle, in the wider area of an intermediate space 55 in wedge shape which is formed between the inner wall 44 and the opposite limit of the driving stop 35 of the multiple edge with its wedge surfaces 39- While the movement of the handle can be carried out without problems, in case of an action in the square 30 by means of the dragging element 35 of the activated multiple edge, on the other hand, is possible only after the play B of the angle of rotation has been exceeded. A permanent deformation of the inner wall 44, conditioned by the material, due to the effect of the moment of rotation from the engagement part of a door or a window can be considered by the user as a problem of operating the handle of the handle. This is at the same time a sign that it is indispensable to change the handle 10, at least, its internal life "and / or other security measure The cross-sectional view of figure 4 shows a partial cut of a handle 10 with a neck 12 of handle and a notch 16 extending axially like a threaded bore 14. A stop body 20 has a guide bushing 22, as well as drilled projections 23 which serve for receiving the fixing screws 26 (the thread was not shown to simplify The stop body 20 is overlapped with a cover plate or a hinged lid 21 which is supported, elevably, by means of a pressure spring 13 in front of the lower part of the neck of the handle. In a concentric manner to the guide bush 22, the stop body 20 has a recess 84 in the lower part, which is provided with curvatures 86, which accommodates an insert 88 in the form of a locking ring 25. In this case, an adjustment notch 24 has been formed for the rotary alloy of the trailing stop 35 of the multiple edge which is connected, in a torsion-resistant manner, with a multiple edge (here: square) 30. The latter has a transverse bore 32 accommodating a stop pin 34, transversely traversing the trailing stop 35 of the multiple edge. On the side of the circumference, cylindrical roller or roller pins 36 are held in pairs or on the trailing stop 35 of the multiple edge.; four pairs are preferred, with each of two rolling pins 36 being a pressure spring 38 respectively. The handle stop 15 of the handle is rotatably guided with a cylindrical part in the guide bush 22 with sliding adjustment and molded by the end of the notch 16 in the neck 12 of the handle. A countersunk screw 18 fixes the driving stop 15 of the handle on the handle 10 when it penetrates into the threaded bore 14 of the neck 12 of the handle and precisely, so that the upper part of an annular flange 54 formed in the stop drag 15 of the handle, is slidingly inside the stop body 20. At the rear, the annular flange 54 has beads 45 that concentrically surround the drag stop 35 of the multiple edge. The peripheral ends, subordinate to the rolling pins 36, of the beads 45 form the sliding surfaces 19. It is recognized that the drawn driving stop 35 has in the example shown four radial arms with peripheral rounds for the sliding adjustment in the locking ring 25. To these arms, recesses 56 are coupled with the cradle surfaces 39, which, together with the rolling pins 36, suspended by a spring in pairs as described above, cause an automatic stop, soon exceeding a set B of a predetermined rotary angle between the square trailing stop 35 and the trailing stop 15 of the handle.

Figure 5a shows the components of this handle in an extended transverse upper view, while Figure 5b reflects the corresponding cross views from below. From this it can be seen that the stop body 20 can be closed after the assembly of the individual parts with a bottom plate 28, the anchor bolts 29 of which can be engaged in the corresponding recesses 49 of the stop body 20. The function of the structure of Figure 4 or 5a and 5b largely corresponds to those of Figures 2 and 3, where an automatic stop by friction closure is possible independently of any preferred position of the handle.

Another embodiment of an automatic stop of the fitting can be seen in the lower views of Figure 6a to 6c. Again, a handle stop 15 within a cylindrical adjustment recess 24 comprises a square drive stop 35 in a concentric manner, without the lateral support surfaces 17, 37 of the drive stops 15, 35 coming into contact with each other. in inactive state. { Fig. 6a). The trailing stop 15 of the two-leaf handle, rigidly connected to the handle, not shown here, has central parts 50 with an inlet 51 respectively up to the square 30, which is housed, axially recessed, in the internal trailing stop 35 , provided with a notch 56 with a shape similar to the inlet 51. The arcuate wings 52 are coupled to the center pieces 50, the ends of which have or form sliding surfaces 19.

Among these, rolling pins or cylindrical rollers 36 are provided separately, which in the radially inward direction have curvatures 31 in the same way on the square drive stop 35. The central parts 50 of both halves of the driving stop 15 of the Handles guide a pressure spring 38, as well as retaining balls 47 with an outside diameter equal to that of the rolling pins 36. The latter are pressed by the spring 38 against the inner wall 44 of the adjustment recess 24, in which recesses or retaining grooves 27 are arranged at equidistant distances, preferably offset at an angle of 90 a respectively. Figure 6b shows a state in which this structure can be rotated to the left, opposite to the position shown above, by the movement of the handle and thus of the drag top 15 of the handle. Here the retaining balls 47 are still engaged by engaging the angles of the notches 27 in the wall 44, while the rolling pins or the coupling parts 36 in contact with the surfaces 19 and sliding of the driving stop 15 of the The handle is moved on a circular guide along the inner wall 44. If the coupling parts 36 are to be received in the recesses 27 in advance, this has been ensured as a result of the orientation of the sliding surfaces 19 and the shape of the notches 27, that the drag stop 15 of the handle pulls the rolling pins 36 from the retention slots 27. Here the rolling pins 36 enter the curvatures 31 of the square drive stop 35, so that it engages and is necessarily dragged with the driving stop 15 of the handle. The balls 47, pressed inward, roll on the inner wall 44. If, starting from the inactive position according to figure 6a, an attempt is made to rotate through the square 30 (Fig. 6c), a corner of the curvature 31 of the square crawl stop 35 will move the rolling pins 36 radially outwardly. In this way, they go to the notches 27 of the stop body 20 and immediately block each further movement of the square drive stop 35. It is recognized that the square 30 can only be turned by a small corner, defined by the set B of turning angle. , until the automatic stop suppresses any further movement. An essential feature of this construction is that a safety is achieved against the drive from the outside in or with the encircling positions.

In order to be able to block a transmission of the moment of rotation from the multiple edge 30 to the handle 10 also outside the indicated locking positions of the handle 10, the construction of FIGS. 7a to 7b provides an adjustment recess 24 with four slots 66 of block and four retention grooves 67, which, as shown in detail in FIG. 8, are in point symmetry with respect to the axis D of rotation of the handle 10 and of the driving stops 15, 35 and are preferably arranged at angles of 30 ° and 60 ° respectively with respect to the longitudinal or transverse axis L, 0 of a stop body 20. The coupling parts 36 between the drag stop 15 of the handle and the drag stop 35 of the multiple edge have been formed as pins of blocking. 51. For locating the indicated positions of the window fitting, it has been made with a pressure spring 68 and retaining pins 47 which are pressed by the force of the spring onto the inner wall 44 of the adjustment recess 24 or in the retention slots 67 in the same way. turning the handle out of the indicated position removes the retaining pins 47 from the retaining grooves 67 against the force of the pressure spring 68 and thereby causes a high torque for the user. The length of the retention pegs 47 have been selected so that they can only be pressed into the retention grooves 67 and not into the locking grooves 66. As shown in FIGS. 8 and 9, the retaining slots 67 have both a larger diameter and longer lengths than the locking slots.

This is also true for locking and retaining pins 36, 47. It is guaranteed that only in the indicated positions of the handle / fitting, the user perceives a high turning moment every 90 ° - The locking pins 36, on the other hand, can be inserted in both the retention slots as in the locking grooves 66, 67 as a result of its -size- Figure 7a shows the structure in a designated position of the handle. The retaining pins 47 are pressed into the retaining grooves 67 due to the force of the spring. The trailing stop 35 of the multiple edge has, in turn, two bends 31 which respectively house a locking pin 36. The latter have as little movement as possible between two sliding surfaces 19 of the trailing stop 15 of the two-leaf handle at the snatch points S, shown schematically in FIG. 8, so that when the stop is rotated of drag 15 of the handle a positive connection between the curvature 31 of the drag stop 35 of the multiple edge and the sliding surfaces 19 of the drag stop 15 of the handle occurs. In this way, no turning movement play is generated between the two driving stops 15, 35, with the exception of a set of turning angle caused by manufacturing tolerances. In the trailing stop 35 of the multiple edge, for each locking pin 36, a pressure spring 70 is fixed in a blind bore 71, whose elastic force is smaller than that of the spring 68 for the retaining pins 47. The locking pins 36 are pressed by the force of the spring against the inner wall 44 of the adjustment recess 24 or in a groove 66, 67. In this way it is ensured that the locking pins 36 slide automatically through the slots 66, 6 If the handle is operated according to operation, the sliding surfaces 19 of the handle stop 15 of the handle push the locking pins 36 onto the circular guide. Outside the grooves 66, 67, particularly in the marked positions of the handle, the locking pins 36 always ensure a positive connection between both driving stops, 15, 35, through which the turning movement is freely transmitted. by the trailing stop 35 of the multiple edge to the multi-edge pin 30. The indicated positions of the handle correspond to the indicated positions of the attached fitting of the vent; With this, a smooth positioning of the sliding rod and correct operation of the window is ensured through the freedom of movement. If the locking pins 36 are pressed in the locking grooves 66 or in the retaining grooves 67 during the pivoting movement, the form drive is annulled and a turning angle clearance is created between the two driving stops 15, 35. and in correspondence with this, also between the handle and the multiple edge pin. As the handle continues to rotate, the locking pins 36 are again pulled out of the grooves by the end edges, which serve as function surfaces 69, or the surfaces of the grooves 66, 67. The brief appearance of the rotation angle set between the indicated positions of the handle is not disadvantageous for the operation of the window, since the indicated positions can be freely transmitted to the window fitting. The elastic force of the pressure spring 70 has been selected so that only an imperceptible locking occurs when the locking pins 36 are pulled out of the grooves 66, 67 against the force of the spring. In case of fracture, the handle coupling structure K is driven with a turning moment from the multi-edge pin 30. if the handle of the window is in a designated position, as in figure 7a, the multiple edge dragging stop 35 can be rotated when the turning moment of the encleving is exceeded. If reached, the position as in Fig. 7b, the locking pins 36 are pressed by the resilient force of the pressure spring 70 into a retaining slot 67 or, as in Fig. 7c, in a locking slot 66, it is In other words, the retention grooves 67 serve a double function as retaining and locking slots. The shape drag of the locking pin 36 between the two driving stops 15, 35 is canceled and the driving edge 30 of the multiple edge is still rotated relatively with respect to the driving stop of the handle-by the displacement of the curvature 31 and its angles 39, which act as the operating surface, the corresponding locking pin 36 is pressed firmly into the locking groove 66 p or 67 and can not return to the inside of the curvature 31 again in the event of a subsequent turning movement. . It now forms a positive connection between the handle stop 15 of the handle and the groove 66 or 67 in the recess 24 for adjusting the stop body 20. If the turning angle set exists between the spaced apart surfaces 17, 37 of the The trailing stop 15 of the handle or the trailing stop 35 of the multiple edge is so large that the bearing surfaces 17, 37 of both trailing stops 15, 35 stumble, a section plus the trailing stop 15 will continue to rotate. the handle The positive connection, caused by the locking pin 36 between the handle stop 15 of the handle and the stop body 20, prevents, however, a further rotation of both driving stops 15, 35 and thus of the pin 30. of multiple edge. The multi-edge pin 30 can be rotated in the manner shown at a maximum angle of 30 °. 'At this angle of rotation, the closing elements of the window fitting are still engaged and an unauthorized opening of the window is not possible. The variant of self-locking variant, already analyzed, does not require a high precision of the measurements of the components, but always guarantees outside the working or locking positions of the handle a reliable block in case of a transmission of a moment of rotation of the multiple edge pin to the handle. In and around the locking positions of the handle there is no set of turning angle between the handle and the multiple edge pin, so that the incorrect operation of the fitting can be efficiently avoided. The high manufacturing costs of the components are reliably avoided. Figure 10a shows the components of a fitting of this type in an extended transverse upper view, while Figure 10b reflects the corresponding cross views from below. From here it can be seen that the coupling structure K can be formed in an inserted element 88 separately. The latter has a cylindrical notch 24 of adjustment in whose inner circumference 44 the necessary slots 27, 66, 61 of locking and retention are arranged. The inserted element is placed on a support 89 in the same way in the stop body 20 and closes it downwards. Accordingly, a bottom plate 28 is no longer needed. The coupling structure can be previously assembled in a simple and convenient way and then inserted into the stop body 20, which favorably influences the manufacturing costs. The coupling parts 36 of the coupling structure K can be configured as bearing pins, cylindrical pins, balls or also with other shapes. While the inner wall 44 of the stop body 20 is provided with recesses 27, these will conveniently have a shape adapted to the coupling parts 36; by changing the locking ring 25 in FIG. 5a, 5b, for example, it is also possible to use components corresponding to FIGS. 6a to 6d, where the notches 86 can simultaneously serve as a retaining groove for the balls 47 of FIG. retention. Another variant embodiment of the handle according to the invention has been represented in three different positions in FIGS. 11, 11b, 11c. The handle (not shown here) is connected to a pin which at the same time forms the handle stop 15 of the handle and is guided linearly by a boundary edge 24 of the fitting, for example, a box or a slot for fitting. The transverse bore in the trailing stop 15 of the handle contains a pressure spring 38 which interacts by means of a retaining ball 47 with a retention slot 48 in the case 20. In the pin or the trailing stop 15 of the handle there is a notch 57 in which a square trailing stop 35 has been arranged parallelepiped- If trailing stop 35 supports a square 30 which, vertically with respect to the plane of the drawing, p. eg, it is transversely spaced from the trailing stop 35. The latter has bearing surfaces 37 at both ends which, in the inactive state (FIG. 1a) with a play B, are opposite the bearing surfaces 17 of the trailing stop. 15 of the handle. The square drive stop 35 has a curvature 31 for receiving a coupling element 36, which can be formed in particular as a retaining pin and supported between the sliding surfaces 19 of the driving stop 15 of the handle - In the inactive state , the retaining pin 36 is in the curvature 31 of the driving stop 35, while the retaining ball 47 rests on the retention groove 48 of the box 20. If the pin or the driving stop is then moved 15 of the handle (Fig. 11b), the ball 47 is unlocked, the pressure spring 38 being pressed, and the latch pin 36 slides or rolls on the inside face of the box. It is recognized that the pin can move freely in the housing or the stop body 20. However, if a force is applied through the square 30 on the square drive stop 35, it raises, with its angular acting surface as wedge, the retaining pin 36 up to the locking slot 27. As a result of this, the driving stop 15 of the pin is locked in its already preset position by the retaining ball 47 and the handle can not be moved (Fig. 11c). The invention is not limited to one of the embodiments described above, but may vary in multiple ways. Thus the automatic stop, which faces the application from the outside of an undesired force, can be activated by means of a friction closure, by a form drag or by combinations with different displacement of the pieces or I03 coupling elements in or near an edge limit 24. This may have friction surfaces and / or undercuts or grooves that support a positive connection with the coupling elements or cause it anyway. In the context of the invention there is also the inverse structure with projections or elevations on or in the edge boundary 24, while in the "internal" drive stop 35, notches are provided, such as locking grooves. One can also think of retaining elements housed in a collapsible manner that fit into a gear formed on the inner circumference 44 of the edge boundary 24. The retention peaks are, for example, in place of the rolling or cylindrical pins 36 under the spring thrust on the outer circumference of the multiple edge drive stop 35. The number of retaining and coupling elements, which may also have different shapes than the configuration of the cylinder and the ball, varies according to the construction of the handle 10 and its stop body 20., the "radial" locking path of the coupling elements 36 can be prefixed from the point of view of the construction according to the load. The connection by key, the binding or interlocking of coupling elements between an edge boundary and a corresponding drive surface is important. All the features and advantages, including the constructive features, the spatial arrangements and the steps of the procedure, which follow from the claims, the description and the drawing, can be essential for the invention both separately and in the most diverse combinations.
