In the housing (6) is a rotatably located hand grip (7) for operation of an all-round toothed pinion and in the housing are two counter-running, longitudinally displaceable toothed slides meshing with the pinion. On the rear side of each toothed slide extends a driver tongue which extends through a common slit of a cover plate releasable connected to the housing.

Description

The invention relates to a fitting according to the general term of the main claim.

Fixed gears of this type are used especially for window or door sashes that move around a vertical axis, whose sash frames are made of extruded profiles made of plastic or light metal. The thrust bearing is placed on the front surface of the wing frame and fixed with screws. At the same time, two grippers protrude through the longitudinal opening of the wing profile jump into the area of the guide channel on the side of the wing bend and are there firmly connected to the halves of the couplings which are movably located in the guide channel and which work together with the two tension rods that are also guided in the guide channel movable in length. By moving the pivoting angle of the handle by 90°, the grippers move towards each other or away from each other, which means that both tie rods get counter-directional motion.

In the case of such persistent transmissions, the aim is to enable left and right abutment with a single design of choice. To change the bearing, the housing of the fixed transmission is turned 180° around the pivot shaft of the lever and transmission gear. However, this turning causes a change in the direction of the turning angle of the handle, which is blocked mainly by the fact that both grippers, which pass through the same longitudinal slot of the base plate, move along their length, with their end faces touching each other.

In fittings according to EP 0 491 133 A1, the housing of the thrust gear is shaped symmetrically on an oblique plane, which extends through the pivot shaft of the lever and the drive gear, perpendicular to the direction of movement of the toothed sliders and thus the tension rods. The case with a flat rectangular cross-section is also symmetrical about its longitudinal median plane, which extends perpendicular to the above-mentioned plane. The longitudinal slit of the cover plate, which holds the toothed slides inside the housing, is moved to the side opposite the longitudinal middle plane of the housing, given by the construction conditions on the wing frame. The toothed runner, where the toothed bar, base plate and grippers are molded in one piece, are shaped symmetrically on an oblique plane, which extends through the middle of the width of the gripper and the middle of the length of the toothed bar. The total length of each serrated slat is doubled according to the required length of action, which requires the extension of the guides on the side of the housing for the serrated slides, to double the length of the serrated slats.

To change the direction of the support, the cover plate must be removed. Then each tooth must be removed from engagement with the drive gear. Now the teeth in the area of their guides have to be moved in the opposite direction to each other so far, until their engagements take a position that is exactly replaced by each other, in which they again come into engagement with the drive gear. Finally, the cover plate is placed again. This procedure must be handled carefully, in order to avoid wrongly changing the toothed slides. Both disassembly and assembly are required, and the housing takes on an oblong shape.

It is also known to change the direction of bearing in fixed transmissions, that for each type of bearing, corresponding toothed slides are used, which are replaced.

DE-P 3 445 170 proposes to have toothed slats on both sides of the toothing and to place the gripper separately on the toothed slide. Moving the direction of the bearing is done by turning each toothed slide 180° around its longitudinal axis, and the change is made by simultaneously moving the catch.

In the form of execution according to EP 0 446 566 A1, each toothed slide is constructed obliquely symmetrically and has two bearings for the grippers. To move the direction of the abutment, the toothed sliders must also be removed from engagement with the drive gear and in each of their guides they must be moved along the length, and finally the engagers are moved.

When changing the direction of contact with fixed transmissions, the cover plate must always be moved, the toothed slider must be separated from the drive gear, the position of the toothed sliders must be changed partially by moving the catchers that are releasably mounted on the toothed slider, and the toothed sliders and the transmission gear must be engaged again, and finally again puts the cover plate.

The task of the invention is to avoid the above-mentioned shortcomings of fittings with persistent gears and to produce a fitting with persistent gears, where when moving the type of abutment it is not necessary to touch the thrust means of the housing with a compact design of the housing and structural simplification of the thrust means.

In order to solve this task, according to the invention, it is proposed that the fitting be made according to the preamble of claim 1 in accordance with the characteristics of the characteristic part of the claim. The toothed sliders are designed and inserted in the housing in such a way that the grippers are placed longitudinally movable next to each other, and in the middle connecting position the levers are so that they mostly cover each other. As a result of such a shape, it is possible to move the pivot angle of the handle from the middle connecting position to both oppositely directed end connecting positions, whereby the longitudinal movement of the catchers that move in the opposite direction is always equal, regardless of whether the handle is directed in one end connecting position downwards, for example with a vertical lever orientation and the free end of the lever or whether the free end of the lever in the other end connection position is directed upwards.

Thus, for each type of abutment, there is available the corresponding area of the pivoting angle of the handle, which are oppositely oriented. Thus, after turning the fixed transmission by 180° around the pivot shaft of the handle and the transfer gear when the handle is arranged in the middle connecting position for moving the type of abutment, the necessary opposite movement of the rotation angle of the handle is guaranteed. After setting the desired type of abutment, block the area of the pivot angle that is no longer needed to move the wing, for example by blocking the handle, drive gear or slider. This closing or blocking can be especially done via a lever located in the bend of the wing frame, i.e. by placing the housing of the thrust bearing on the front surface of the wing frame, for example, by means of a connecting element that connects the thrust bearing to the tie rods. This makes it possible to move the type of abutment without disassembling or assembling the component parts of the fixed transmission, and the possibility of errors that occur as a result of the above is excluded. No additional cost is required for the construction, especially since the toothed slides can be constructed in one piece. Despite the lateral movement of the longitudinally moving plane of the gripper towards the longitudinal median plane of the thrust gear housing, two fastening screws are sufficient for fixing the thrust gear to the wing frame, which are placed on the same side of the longitudinal median plane of the housing. The length of the housing is also reduced, because the length of the toothed slat of the toothed slide no longer has to correspond to the double path of the longitudinal movement.

In the case of the connecting element, which is located in the guide channel on the folding surface of the wing frame, the halves of which are connected to the connecting rods, their sockets are located in the middle connecting position for a tight connection by mechanical forces with the grippers of both toothed slides, one above the other and during movement. turning angle of the handle, the halves of the connecting element move towards each other, with one half covering the other.

In the case of fittings with toothed sliders with a cross-section in the shape of the letter Z, whose base plates placed parallel to the cover plate are unequally wide, and the width of the longitudinal slot possibly corresponds to the thickness of the gripper, it is recommended that the thickness of each gripper in a symmetrical oblique plane be adapted to half the width of the longitudinal slot, and that the adjacent side walls of the receiver abut one another in the middle connecting position. The required space in the transverse plane of the housing thus remains unchanged, since the total thickness of both grippers corresponds to the thickness of the hitherto common grippers. At the same time, the receivers can lean on each other.

The guidance of both toothed sliders during their counter-directional movement is improved by the fact that one of the toothed sliders has a support bar that protrudes above the adjacent plane of the gripper and which is placed in such a way that it engages under the longitudinal groove of the other toothed slider. The support bar and the longitudinal groove correspond to the thickness of the base plate of the gear slide.

In order to facilitate the introduction of the gripper into the associated sockets during the placement of the fixed transmission on the wing frame, the halves of the connecting element are movably fitted in the guide channel along the length, the free end of each gripper has a bevel for introduction.

If each half of the connecting element has a sleeve suspended in the bore of the thrust rod and guide bars that engage behind the undercut of the guide channel, in order to achieve a compact design of the connecting element, it is advantageous that one half of the connecting element, at least in the area of acceptance for one of the grippers, is shaped so that is thinned to a smaller width and that this thinned end is guided in the longitudinal recess of the second half of the connecting element.

The free front surface of the tapered end of one half of the connecting element abuts in the middle connecting position on the end boundary wall of the longitudinal recess of the other half of the connecting element, so that without additional effort, the locking position of both halves of the connecting element blocks the range of motion of the pivoting angle of the lever, which after connecting the gripper of the persistent transmission with a connecting element, is no longer necessary.

In order to simplify the assembly of both halves of the connecting element that are inserted into the guide channel of the wing frame and for the simultaneous improved support of the tapered end of one half of the connecting element, it is advantageous that the tapered end of one half of the connecting element has a guide bar that engages under the other half of the connecting element by sides of the longitudinal recess and to limit the reception with transverse extensions that protrude above the longitudinal recess. By means of guide slats and transverse extensions that engage one - or both sides over the longitudinal recesses of the second half of the connecting element, the thinned end is guided, held and supported on the other half of the connecting element on all sides. The acceptance of the second half of the connecting element can be formed by a flange that extends parallel to the longitudinal recess and completely covers it.

It is especially expedient that the boundary walls of each receiver have one undercut and that each receiver in the area of the front surfaces is equipped with a particularly suitable narrowed section, in order to maintain a sufficient force transmission surface with a specifically lower load. At the same time, this form enables it to be accepted in the direction of another form of open acceptance. The thickness of the package in the receiving area can thus be kept low. At the same time, the undercuts that engage one another prevent the undesired lifting of the gripper from the associated sockets

The grips of both halves of the connecting element are extended in the plane of the gripper over the entire width, so that in that plane they are open on both sides and it is possible to insert the gripper of the toothed slides on the side of the fixed transmission, on both sides of the connecting element.

The subject of the invention is explained in a schematic representation using a drawing of an exemplary embodiment.

The window according to figure 1 and 2 consists of a fixed frame 1 and sash 2, whose frame 4 is movable by means of hinges 3 on the fixed frame as a hinged sash, i.e. pivoted around a movable axis formed by hinges. On the side of the wing 2 facing away from the moving shaft, on the front surface 12 of the frame 4, the support gear 5 with its housing is placed and fixed by means of fastening screws. The housing 6 has a rotatably mounted lever 7, which acts on the tensioning rods 8, 9 connected to each other by the connecting element 10, and which tensioning rods move in opposite directions, in order to block or unblock the wing 2 and the fixed frame 1.

Picture 1 shows the right side, and picture 2 the left side. The lever 7 of the fixed transmission 5 is in the sub-pin, extended position in the horizontal, with the free end 11 directed towards the moving shaft. This represents the intermediate connection position, in which wing 2 is unblocked and thus movable around the movable shaft. The end connection position is shown in a diagram, where the lever 7 is directed vertically with the free end 11 facing downwards. This represents the blocked connection position in which the wing 2 is blocked against the fixed frame 1. Figures 3 and 4 show the construction of the fittings in more detail, especially of the persistent transmission 5 and the connecting element 10.

The neck 14 of the handle 7 is placed in the housing 6 of the fixed transmission 5, which is covered by the cover plate 13, which has a toothed drive gear 15 on it, which works together with a toothed slide 16 of a smaller width and a toothed slide 17 of a larger width. Both toothed slides 16, 17 have a cross-section in the shape of the letter Z and consist of a toothed slat 18, a base plate 19 and a catch 20. The toothed slats 18 engage in the guides 21 of the housing 6, which extend along the longitudinal walls in the section of the flat rectangular, oblong housing 6 and come into engagement with the diametrically opposite peripheral sides of the drive gear 15. In order to keep the gear slides 16, 17 inside the housing 6, their lower side is closed with a detachable cover plate 22, which has a longitudinal slot 23 for the passage of the engagement gear 20.

In the fixed transmission 5 placed on the wing 2, the grippers 20 work together with the sockets 24 of the connecting element 10, which is movably inserted along its length in the guiding channel 25 on the folding surface 26 of the wing 2, in which the tension rods 8,9 are also located. The undercut shaped guide channel 25 is part of a hollow profile consisting of light metal, from which the frame 4 of the wing 2 is formed.

The connecting element 10 is formed from two connecting halves 27, 28, as can be seen in Figures 9 and 10. Each connecting half 27, 18 has a sleeve 29 at one end for suspension in the hole 30 of one of the tension rods 8, 9. Each half of the connecting element 27,18 has guide bars 31 for rear engagement with guide channel undercuts 25. Half of the connecting element 28 is on one part of its length that extends over the receiving area 24, tapered to a narrower width. This tapered end 32 of the half of the connecting element 28 is equipped with guide slats 33 that protrude laterally. Acceptance 24 is limited by two transverse extensions 34, which on both sides exceed the width of tapered end 32.

The receptacle 24 of the second half of the connecting element 27 is located in the flange 35, which is placed at such a distance from the guide bars 31, that the receiving area 24, when the half of the connecting element 24 is inserted into the guide channel 25, is placed outside the guide channel 25. from the front surface 37 of the half of the connecting element 27, which is located next to the other half of the connecting element 28, extends over the area of the recess 24 and thus covered by the flange 35, the longitudinal recess 36 for the solid and movable reception of the stationary end 32 of one half of the connecting element 28.

The tapered end 32 engages with its guide slats 33 below the half of the connecting element 27 and with its transverse extensions 34 engages over that half of the connecting element 27 to both sides of the longitudinal recess 36. The border wall 38 receives 24 which are placed obliquely in the direction of longitudinal movement, have one undercut 39 each.

In figures 1 and 2 and 5 and 7, respectively, in the middle connecting position of the thrust gear 5 with the unblocked wing 2, the handle 7 extends horizontally. to another. The housing 6 is shaped symmetrically to the oblique plane G, which extends through the pivot shaft 41 of the lever 7 and the drive gear 15 and perpendicular to the longitudinal orientation of the housing 6, and thus perpendicular to the direction of longitudinal movement of the toothed slides 16, 17 of the connecting element 10 and the tension rods. 8, 9. Likewise, the housing 6 is symmetrical with respect to the longitudinal middle plane L. The toothed slides 16, 17 are also symmetrical with respect to the mentioned direction of longitudinal movement of the inclined plane Z which extends vertically through the toothed slat 18 and the catchers 20. In the middle connecting position of the inclined plane With both toothed sliders 16, 17, they coincide, with the arrangement of the catchers 20 overlapping. At the same time, the transverse planes Z lie in the transverse plane G.

Starting from the middle connecting position of the thrust gear 5 according to Figure 5, the thrust gear is ready for the installation of the right abutment, as in Figure 1. For this purpose, the grippers 20 are pushed through the longitudinal opening 42 in the jump 43 of the frame 4 of the wing 2 and introduced into the grips 24 of the connecting element 10. This is facilitated by the introduction slopes 44, placed on the free ends of the catch 20. After fixing the abutment carrier 5 on the wing 2, the hardware can be handled. For this purpose, the lever 7, starting from figure 1, is turned 90° downwards in a clockwise direction. In this way, the drive gear 15 firmly connected to the neck 14 of the handle 7 rotates around the pivot shaft 41, and the toothed slide 16 from Figure 5 moves up, while the toothed slide 17 moves down. This opposite longitudinal movement of the toothed sliders 16, 17 is stopped by the contact of the front edges 45 of the toothed sliders 16, 17, on the walls 46 of the housing 6. This achieves the final connecting position of the lever 7, which is shown in dashes in Figure 1. During the change of the angle of rotation, the grippers 20, which move longitudinally in the opposite direction, move the half of the connecting element 20 with the connecting rod 8 up, and the half of the connecting element 28 with the connecting rod 9 down, achieving blocking between the wing 2 and the fixed frame 1.

When returning the handle 2, the tapered end 32 of the half of the connecting element 28 still enters the longitudinal recess 36 of the half of the connecting element 27. This movement is limited by the contact of the front surface 47 of the tapered end 32 of the half of the connecting element 28 to the end boundary wall 48 of the longitudinal recess 36 of the half of the connecting element 27. Lever 7 is again in the middle connecting position. The limit of the turning angle is when mounted on the wing 2 and with the halves of the connecting element 27, 28 of the connecting fixed transmission 5, adjusted to 90°.

If the support is changed, starting from the arrangement of the thrust gear 5 according to figures 1 and 5 to the arrangement according to figures 2 and 7, the thrust gear 5, which has not yet been placed on wing 2, must be turned as a whole by 180° around the pivot shaft 41. Yes in order to reach the end connection position with the vertical position of the handle 7 and the free end pointing down, the opposite movement of the pivot angle should be performed by 90° counter-clockwise. This also causes the catchers to move in the opposite direction as with the right abutment.

Since the grippers 20, starting from the middle connecting position, can move freely from each other in both longitudinally moving directions, the handle 7 of the fixed transmission 5 can, when it is not yet installed on the wing 2, be rotated to both end connecting positions, i.e. by 90° in clockwise, as well as 90° counter-clockwise, whereby the grippers 20 move equally, only in opposite directions.

After rotating the fixed gear 5 around the pivot shaft 41 by 180°, in that position it must be mounted on the wing 2 of figure 2. If the handle 7 is turned downwards by 90° counter-clockwise, the toothed slider moves upwards, and the toothed slider 17 downwards. The final connecting position is again achieved by touching the front edges 45 of the toothed sliders 16, 17, on the wall 46 of the housing 6. The limit when returning the handle 7 is again achieved by touching the front surface 47 of the half of the connecting element 28 on the wall of the end stop 48 of the half of the connecting element 27.

Thus, the thrust bearing has a left and right support, i.e. the left and right bearing can be used without removing the cover plate and changing the structure of the thrust bearing 5.

The cover plate 22 no longer has to be releasably attached to the housing 6, as was necessary until now, in order to enable the change of toothed slides or catchers. The cover plate 22 has only one more purpose, to hold together the parts placed in the housing 6 and to protect them, so that they cannot be lost. The cover plate can even be completely omitted if the toothed sliders 16, 17 are inserted into the housing 6 by appropriate structural measures, so that they cannot be lost.

To improve the mutual support and to facilitate the insertion of the toothed sliders 16, 17 in the production of the thrust gear 5, the toothed slider 16 has a support bar that protrudes from the base plate 19 through its side walls 40 and which enters the longitudinal groove 50 of the second toothed slider 17, and supports that toothed slider 17.

Between the lever 7 and/or the drive gear 15 and the housing 6, federating stop elements can be provided in a known manner, with a stop angle distance of 90°, so that the lever 7, after moving the pivot angle by 90°, is fixed in the middle with a given holding force in the connecting position, that is, in the final connecting position, so that the danger of the lever 7 coming to unsightly intermediate oblique positions deviating from the 90° position is reduced.
