Description

The invention relates to a locking handle fitting to be operated by means of a handle on windows, doors or the like, in which a locking bar can be moved forward from an open position by means of a gear such that the end of the locking bar profiled for hooking engagement in the locking bar through the locking bar longitudinal slot into the Opening of a counter-closing part is retractable.

Such a fitting is known from DE-OS 29 00 632, wherein, starting from the open position of the locking bracket fitting, the locking bar penetrates the longitudinal slot of the locking bracket in a first closed position and dips into the opening of the counter-locking part in the following second closed position. To open, the handle handle must be operated in the opposite direction, namely by pulling the locking bar back two turns.

Furthermore, from DE-OS 38 44 627 a fitting is known which forms an additional security for a window sash equipped with rebate-side locking means. This fitting is placed on the wing in such a way that the flat-shaped gear is inserted between the wing surface and the handle handle to be removed before assembly. The gear mechanism controls locking bars that can be extended upwards and downwards against each other, the free ends of which dip into counter-locking parts on the frame in the locking position. The locking bars are controlled by a nut which engages on connecting slides, which the drive mandrel of the handle handle passes through. There is a slot / pin control, so that the locking bars, starting from their locking position, in which the locking bars are fully extended, are retracted after a first 90 ° rotation of the nut in a position in which they are completely out of engagement with the Counter cast parts are available. In this position, the corresponding wing can be rotated about a vertical axis of the window. With a second 90 ° turn of the nut, the lower locking bar is then moved out again, with its free end dipping into the lower counter-locking part. The upper locking bar, however, remains in its retracted position. In this position, the window sash can be tilted.

The object of the invention is based on the development of a generic fitting with regard to simplified operation and its security function.

This problem is solved in a generic locking bracket fitting by a reversing gear for controlling the locking bar such that a rectified rotation of the gear handle handle is translated into a return stroke of different sizes of the locking bar.

As a result of such a configuration, a generic fitting is specified which, in addition to simplified operation, is distinguished by an increased security value. If the locking bracket fitting is in its closed position, that is to say when the locking bar is retracted into the opening of the counter-locking part, then the transmission handle handle becomes only by partial rotation The locking bar is retracted into the open position so that it cannot be brought into hooking engagement with the locking bar. A previously locked wing is accordingly pivotable about its axis of rotation. In the prior art, on the other hand, two rotations connected in series must be carried out in order to bring the locking bar fully into the open position. If, on the other hand, the interlocking engagement between the profiled end of the locking bar and the locking bracket is desired, which only allows a gap opening of the wing, then the rotation of the gear handle must be continued in the same direction, the locking bar being displaced in the direction of the locking bracket. This outward stroke in the direction of the counter-closing part is smaller than the previously generated return stroke. The subsequent turning back of the gear handle leads after a partial rotation initially to a pulling back of the locking bar into the open position, so that the wing can be pivoted about its axis of rotation. Subsequent further partial rotation then brings about the locking position of the locking bar, in which its profiled end dips into the opening of the counter-locking part. The foregoing illustrates that from the open or closed position, only a partial rotation of the gear handle is required to open the sash.

The subclaims represent advantageous developments of the invention. When used on turn / tilt windows, the counter-closing part can be arranged in the upper region of the fixed frame or the like in such a way that the swing-out locking bracket runs horizontally and can be swung out perpendicular to the window plane. The spring loading of the locking bracket ensures that it always assumes its correct position. The window sash is moved from its rotary kiln position to the closed position brought, it is ensured that the profiled end of the locking bar can always move into the counter-closing part opening. In the tilt-open position of the window sash, the interlocking engagement between the locking bar and the locking bracket secures the unauthorized opening of the window sash from the outside. Regarding this locking bar, it is the upper one. The gearbox can be designed so that a lower locking bar is also shifted, which moves the latter into the counter-locking part assigned to it in the tilted position. Based on the actuation of the turn / tilt window, there are 90 ° partial rotations of the handle. Due to the free movement of the upper locking bar in the tilt position, the locking bar can be extended by a corresponding amount without any further actuation of the handle, so that the interlocking engagement between the profiled end of the locking bar and the locking bracket does not lead to canting. Rather, the corresponding height difference between the profiled end and the locking bracket is compensated.

A further preferred embodiment, which in particular simplifies the manufacture of the fitting, provides that the connecting slides are each essentially mirror-symmetrical and each can be driven by one half of a split nut. The nut halves are preferably also mirror-symmetrical. As a result of this embodiment, the transmission consists of two mirror-symmetrical, sandwich-like superimposed gear components, which can also lie in mirror-symmetrical half-shells. One gear half drives the upper locking bar and the other the lower one. In an advantageous manner, the gear mechanism of the fitting is designed such that the connecting slide is in each case on a U-leg a first guide slot opening into the U-leg space is provided, from which a control pin assigned to each nut half emerges during the first 90 ° rotation, starting from the closed position. The control pin and guide slot form a slot-pin control at least in a partial area of the first 90 ° rotation. According to a further development, a drive pin is assigned to the one leg of the connecting slide, which interacts with a first slot-like control curve of the nut which is open towards the nut circumferential surface. During the transition from the first 90 ° rotation to the second 90 ° rotation, the drive pin emerges from the first control curve and moves along the second control curve past the nut circumferential surface during the second 90 ° rotation, and then in the the gear position allowing the tilt position to be attached to the stop shoulder. The second control curve can at least partially have an involute shape. The invention provides that the drive of the connecting slide from the first 90 ° position to the second 90 ° position is achieved in that the control pin assigned to the nut engages in a second guide slot which is arranged on the other U-leg of the connecting slide is and is open to the U-leg space. The clearance is preferably achieved in that the second guide slot for the upper locking bar has a widening in the direction of displacement of the connecting slide. This measure allows the connecting slide to be displaced by the amount of widening without a nut turn. The clearance is limited by the stop of the control pin on the side walls of the second guide slot which extend transversely to the direction of displacement of the connecting slide. The drive pin strikes when the fitting is designed last only after passing through the free passage on the stop shoulder, so that this also prevents further extension of the connecting slide.

1 shows a tilt and turn window, the window sash 40 of which can be rotated about its X axis and can be tilted about its Y axis. For this purpose, the window sash 40 is connected to the window frame 41 by means of hinges 30 and 31, the hinge 30 being able to be uncoupled in order to achieve the tilt position. As is shown in particular in FIG. 4, the window sash 40 has locking elements 34 on the rebate side which are designed as locking pins which can be displaced by a handle 8.

Between the handle 8 and the window sash surface, as shown in particular in FIG. 4, there is a flat-shaped gear 9 of a locking bracket fitting. Ratchet rods 2, 3 protrude upward and downward from the transmission 9, which are guided on the wing surface by means of bearing elements 32. The Bearing elements 32 can be designed as screws, which extend through the longitudinal slots of the locking bars 2, 3 and overlap the longitudinal slots with their heads.

Aligning with the locking bars 2, 3, counter locking parts 6, 7 are arranged on the window frame 41 at the top and bottom, into which the free ends 4, 5 of the locking bars 2, 3 are immersed in the locking position shown in FIG. 1. The counter-closing parts 6, 7 are connected to the window frame 41 by means of screw connections. In the locked position, the free ends 4, 5 of the locking bars 2, 3 enter shaft-like openings 6 ', 7' of the counter-locking parts 6, 7. The upper counter-locking part 6 has a locking bracket 15 which is arranged between the opening 6 'and the window sash 40 and which is pivotably connected to the counter-locking part 6 by means of a bolt 27. The locking bracket 15 has a longitudinal slot 16 which extends almost over the entire length of the locking bracket 15. In the locking position shown in Fig. 1, the locking bar 2 extends through the longitudinal slot 16 of the locking bracket 15 and dips with the free end into the counter-closing part opening 6 '.

As shown in particular in FIGS. 6-14, the gear 9 has two superimposed, essentially identical, half-shells 9 ′, 9 ″ forming the gear housing, which have screw through openings 33 through which the fastening screws of the handle 8 are guided can. Furthermore, the half-shells 9 ', 9''each have a central opening, in which openings two nut halves 13, 14 containing square insertion openings 24 are rotatably mounted with their collars. In the square insertion openings 24 engages in a form-fitting manner with a square mandrel, not illustrated, which is coupled to the handle 8 and which in turn projects with its free end into a window gear assigned to the window sash 40. With regard to the handle 8, it is a known handle which can be locked by means of a key 35.

Within the gear half shells 9 ', 9' 'connecting slides 10, 11 connected to the locking bars 2, 3 are guided on the floor or the ceiling. The connecting slides 10, 11 are essentially U-shaped, so that the screw passage openings are not covered by the connecting slides 10, 11 in any gear position. The width of the connecting slides 10, 11 corresponds approximately to the clear width of the housing half-shells 9 ', 9' ', so that the connecting slides 10, 11 are guided securely. The two nut halves 13 and 14 extend one above the other between the two connecting slides 10, 11. The broad sides of the nut halves at least partially overlap the U-legs of the connecting slides 10, 11 and ensure reliable guidance of the connecting slides.

The connecting slides 10, 11 which can be driven in opposite directions by the two nut halves 13, 14 each have a first guide slot 17, 17 'on their one U-leg 10', 11 ', which runs essentially transversely to the direction of displacement of the connecting slides 10, 11 and to U-leg space is open. In this first guide slot 17, 17 ', a control pin 18, 18' of the nut halves 13, 14 lies in the locking position shown in FIGS. 6 and 7. A drive pin 20, 20 'arranged on the same U-leg 10', 11 'lies in this position in a claw-like manner Recess of the nut halves 13, 14, which recesses are designed as first control curves 19, 19 'of the nut halves 13, 14. When the connecting slides 10, 11 are shifted from the position shown in FIGS. 6 and 7 into the rotational position illustrated in FIGS. 9 and 10, together with a nut rotation through 90 ° counterclockwise by means of the handle 8, the control pin 18, 18 'passes through the guide slot 17, 17 'and exits this first guide slot 17, 17' shortly before the 90 ° rotation has ended. During this shift, the control pin 18, 18 'drives the connecting slide 10, 11 by acting on a side wall of the first guide slot 17, 17'. During the first 90 ° rotation, the drive pin 20, 20 'is acted upon by the first cam 19, 19' of the nut halves 13, 14, whereby the connecting slide 10, 11 in its max. Inference position (Fig. 9, 10) are shifted.

In this position, as is particularly shown in FIG. 2, the free ends 4, 5 are completely disengaged from the counter-closing parts 6, 7, so that the window sash 40 can be rotated about its vertical axis xx.
From the 90 ° position of the gear 9 shown in FIGS. 9 and 10, this can be transferred along with an outward displacement of the connecting slides 10, 11 into the gear position shown in FIGS. 11 and 12 by turning the nut halves 13, 14 by means of the handle 8 . During this rotation, the control pin 18, 18 'of the nut halves 13, 14 engages in a second guide slot 23, 23' of the control slide 10, 11. This guide slot 23, 23 'is arranged on the opposite U-leg 10'',11''and also extends transversely to the direction of displacement of the connecting slide 10, 11. In that the control pin 18, 18 'enters the second guide slot 23, 23', after further rotation of the nut halves 13, 14 it acts on the side wall of the second guide slot 23, 23 'and displaces the connecting slide 10, 11 in a partial manner pre-closed position shown in Figs. 11 and 12.

In this position, which is shown in particular in FIGS. 3 and 4, the lower locking bar 3 enters with its free end 5 into the associated counter-locking part 7. In this position, the upper locking bar 2 does not enter the counter-closing part opening 6 ', but the free end 4 of the locking bar 2, which is profiled as a hammer head, dips into the longitudinal slot 16 of the locking bracket 15. In this position, the window sash 40 can be tilted, the locking bracket 15 which can be pivoted about the bolt 27 entering a pivoting position, as is shown in particular in FIG. 4. In this swivel position, the projections 25, 26 of the hammer head overlap the flanks 15 'of the locking bracket 15, so that lifting the locking bracket 15 over the free end 4 of the locking bar 2 is excluded.

In order to prevent the locking bar from tilting, the transmission 9 uses a free passage in the 180 ° position, as is shown in particular in FIGS. 12-13. For this purpose, the second guide slot 23 of the connecting slide 10 has a widening which is substantially wider than the diameter of the control pin 18. This allows the connecting slide 10 to be displaced in its direction of displacement by a path F, which is limited by the fact that the control pin 18 has the side walls of the second control slot 23.

As shown in Fig. 11, the drive pin 20 'in the 180 ° position against a stop shoulder 21' of the nut 14, which adjoins a second cam 22 '. The drive pin 20 of the connecting slide 10 strikes only after a further displacement of the connecting slide 10 by the clearance F on the stop shoulder 21 (see FIGS. 12 and 13). During the rotary movement from the 90 ° position to the 180 ° position by means of the handle 8 (see FIGS. 9 and 10 and FIGS. 11 and 12), the drive pin 20, 20 'moves along the control cam 22, 22' Nut halves 13, 14. The control cam 22, 22 'has an approximately involute shape.

In order to always fix the locking bracket 15 when the locking rod 2 is not in engagement in a defined position running parallel to the frame, the locking bracket 15 has a return spring 36 which is arranged on the bolt 27 and is designed as a helical spring.
