In the drawing, the subject matter of the invention is based on exemplary embodiments shown. It shows

Fig. 1 in a schematic side view the possibility of variation of a edge gear according to the invention,

Fig. 2 in a spatial rear view and partially assembled state a first design option for an edge gear according to the invention,

3 shows a further design option in a three-dimensional representation and a rear view for an edge gear according to the invention,

FIG. 4 shows a section along the line IV-IV of FIG. 2, FIG. 5 shows a section along the line V - V in FIG. 2 and FIG. 6 shows a section along the line VI - VI in FIG. 3.

According to FIG. 1, an edge gear according to the invention has a flat one Everted rail 1, the length dimension 2 of which corresponds to the largest occurring length of an edge gear. On the back of this faceplate 1, a gear housing 3 is rigidly attached, for example halfway along the length, in which a pinion 4 or a similar drive member is mounted, which is connected to a rack piece 5 or another suitable output member is in engagement, which is guided in the gear housing 3 longitudinally.

With the rack piece 5 drive rod pieces 6, 7, 8, 9, 10, 11 different length dimensions can be optionally coupled, each of which carries at least one locking and / or locking member 12.

In this way, edge gears are of different length dimensions easy to assemble, all that is necessary is the faceplate 1 in adaptation to the length of each with the rack piece 5 or the like, cut off coupled drive rod pieces 6 to 11 accordingly. In this case, drive rod pieces of the same length with the toothed rack piece can be on both sides of the actuating gear 5 or drive rod pieces of different lengths can be coupled to the toothed rack piece 5.

If necessary, however, it is also possible to _s only connect a drive rod piece to the toothed rack piece 5 on one side «:

In any case, those fastened to the connecting rod pieces 6 to 11 prevail Closure and / or locking members 12 the faceplate 1 in the area of longitudinal slots in such a way that they are lying on the front of the faceplate with associated counter-locking members in a known manner Way can work together.

In the embodiment of an edge gear according to FIG. 2, the toothed rack piece 5, which is guided in a longitudinally displaceable manner in the gear housing 2 behind the faceplate 1, is provided with a dovetail-shaped cutout 13 at its ends. Each of the connecting rod pieces 6 to 11 to be coupled with the toothed rack piece 5 has at its "KJupplungsende; a corresponding dovetail-shaped coupling shoulder 14, with which it can be brought into engagement in the coupling cutout 13 if necessary

20S842 / 0043

the rack piece 5 and the drive rod piece (s) 6 to 11 in the same plane on the back of the faceplate 1.

When the clutch cut-outs 13 of the rack piece 5 check in each switch position are of the actuating gear outside of the transmission case 3, there is a need to ensure that the coupling lugs 14 of the positioning-bar 6 to 11 at all times init them in engagement remain. For this purpose, in the embodiment according to FIG. 2, the connecting rod pieces β to 11 are provided with a longitudinal slot 15 in the vicinity of the end carrying the coupling attachment 14. The faceplate 1 carries head bolts 16 _S on its rear side whose shaft 17 is adapted in diameter to the width of the slots 15, and whose head part 18 on diametrically opposite sides AMlachungen 19 hai _s whose distance from one another is equal to the shaft diameter. In the case of flattened areas 19 lying parallel to the longitudinal direction of the faceplate, the drive rod pieces 6 to 11 can be pushed onto the head bolts 16 from the rear; by simultaneously hooking the coupling lugs 14 into the coupling cutouts 13, then the head bolts 16 in the faceplate 1 are rotated ₉ so that you can see the flats IS of their head part 18 extend transversely to the longitudinal direction of the faceplate and the drive rod parts B to 11 ,, the head parts 18 thus overlap the connecting rod pieces 6 to 11 and hold them securely with your tooth = rod piece 5 in a form-fitting engagement,

If it is intended to use the edge gears not only in the cross-section T-shaped profile grooves of the flight malt circumferential surface, which see SküLpscMene 1 in the Eereieli of the wider groove profile part with its bearing gears, but also the EC string and gears in "" rectangular profiles _{a = fozw o} - on which ^ per sash fold circumferential surface are to be placed, then it is

moderate, head bolt 16 in the form described in the vicinity of each fastening point between the edge gear and the one carrying it To arrange wings, namely in this case the head bolts act 16 as a spacer that support the faceplate 1 against the wing and thereby the mobility of the connecting rod pieces 6 to

11 underneath the faceplate 1.

In the edge drive according to FIG. 2, pins of circular cross-section are provided as locking and / or locking members. In order to this to lie on the front of the faceplate 1 when coupling the drive rod pieces 6 to 11 with the toothed rack piece 5 come, the faceplate 1 is provided with longitudinal slots 20, the length of which is at least the diameter of the pin

12 is designed larger than the thrust of the rack piece 5. At one end, the longitudinal slots 20 are widened 21, which is somewhat larger in cross section than the cross section of the pin 12. Through these extensions 21, the pins 12 can be pushed through from the back of the faceplate 1 before the coupling of the drive rod pieces 6 to 11 is made with the rack piece 5.

As Fig. 4 clearly shows, the locking pins 12 have immediately above the drive rod piece 6 to 11 a cross-sectional constriction 22, the Height is slightly greater than the thickness of the faceplate 1 and in the area of which the pin 12 is one of the normal width of the longitudinal slots 20 has adapted diameter.

Through the cross-sectional constriction 22 of the pin 12 on the one hand an exact guidance of the drive rod piece 6 to 11 within the part of the longitudinal slots 20 having the small width is achieved,

200842/0043

when the drive rod pieces 6 to 11 are coupled positively to the toothed rack piece 5. On the other hand, the drive rod piece is also used 6 to 11 secured against unintentional lifting from the back of the faceplate 1 in the area of the locking pin 12.

Of course, it is also easily possible as a closure and / or Lock members 12 pin to the connecting rod pieces 6 to 11 firmly to be attached, which protrude on their entire, from the connecting rod piece Length range have a constant cross-section and thus inserted through longitudinal slots 20 in the faceplate 1 from behind that have a constant width over their entire length. In this case, however, it is then expedient to attach head bolts 16 on the faceplate 1 in the vicinity of the longitudinal slots 20, after the connecting rod pieces 6 to 11 have been slotted on to secure their position in their longitudinal slots 15, they can be rotated are as already described above. The same possibility naturally also exists when as a closure and / or Lock members 12 instead of circular pins, flat locking webs, so-called swords, are attached to the connecting rod pieces 6 to 11.

The embodiment of an edge gear according to FIG. 3 differs from that of Fig. 2 essentially in that the drive rod pieces 6 to 11 with the rack piece 5 by a can be connected consisting of a hole 23 and a pin 24 coupling, in which, for example, the connecting rod pieces 6 to 11 the rack piece 5 overlap with a crank 25. In this case, too, the coupling connection can be provided by head bolts 16 be held securely in engagement. But there is also the possibility of instead of the head bolts 16 guide parts with a U-shaped cross-section 26 to use the connecting rod pieces 6 to 11 and given

if the ends of the rack piece 5 with their legs grip around the longitudinal edges and, for example, by means of elastically flexible pegs in corresponding holes in the faceplate 1 can be impressed from the rear side »The pins 28 can be made of plastic, at least in their elastic partial area and reach through the longitudinal slots 15 in the drive rod pieces 6 to 11 from the rear. The guide parts 26 are located near the fastening points for the edge gear on the Window or door sashes are provided in such a way that they can act as spacers when the edge gear is in a rectangular cross-section Groove inserted or simply on the unprofiled sash fallopian surface is put on.

Fig. 6 makes it clear how the guide parts 26 are arranged on the edge gear and act as a spacer with respect to the wing can.

Since with an edge drive according to the invention, a larger number of different bearing drive rods pieces 6 to 11 behind the faceplate

1 with the rack piece 5 can be optionally coupled, in which the locking and / or locking members , based on the initial length

2 of the faceplate 1 come to rest at different points, the faceplate 1 is equipped over its entire length at a large number of predetermined points with longitudinal slots 20 for the locking and / or locking members 12 to pass through. The distances between the longitudinal slots 20 correspond to the amount by which the locking and locking members 12 in the different lengths of connecting rods 6 to 11, based on the seat of the actuating gear on the faceplate I ₁ are offset from one another.

Since with each edge gear that is used, only a single one is used Longitudinal slots 20 of the faceplate 1 are penetrated by a locking and / or locking member 12, it is useful to all Longitudinal slots 20 through insert pieces, for example made of plastic, to close and only those slots 20 from the plastic inserts to clear, which are required for the passage of the locking and / or locking members 12.

So that a secure attachment of the edge gear to the window or Door leaves is possible, the faceplate 1 has in each case half the distance between two successive longitudinal slots 20 through holes for fastening screws which then penetrate the connecting rod pieces 6 to 11 in the region of a longitudinal slot 15.

Different from those shown in the drawing and described above Edge gear versions, it is also possible to connect the coupling points 13, 14 or 23, 24 between the rack piece 5 and the Drive rod pieces 6 to 11 to be arranged so that they are continuously within the gear housing with the normal adjustment path of the edge gear and can only be moved out of the gear housing 3 for the purpose of coupling and uncoupling. For this it is only necessary the angular range of rotation of the pinion 4 in the gear housing 3 for normal actuation by releasable stops, for example to 90 or 180 limit. After removing these stops, the pinion 4 can then be moved beyond the angular rotation range of 90 or 180, so that thereby the coupling points between the rack piece 5 and the connecting rod pieces 6 to 11 can be pushed out of the gear housing 3. Such a stop can, for example be formed by a pin that transversely into the gear housing 3 to the plane of movement of the pinion 4 can be inserted and with the front

- 13 jumps on the pinion 4 then work together as counter-stops.

The inventive design of an edge gear makes it It is possible to assemble a large number of different edge gears with a minimum of parts. It is not only the entire length of the edge gear is variable, but also the seat of the operating gear. It is even possible that Actuating gear to be arranged in the immediate vicinity of one end of the edge gear, so only one drive rod piece from one side Provide actuating gear starting.
