Description

The technical field of the invention are counter-rotating transmissions for use in a frontal recess of a wing. The box in which the transmission is arranged is L-shaped and its two legs, one of which is long, are flat in shape, resulting in the definition of the term "L-shaped gearbox flat box". This gear is driven by an operating handle which engages through a corresponding recess with a polygonal rod through the long leg of the flat L-gear box (gearbox flat box).

Without such a gear flat box with L-shaped configuration, EP-A 501 803 (Regent Lock) for controlling "shooting bolts" 21,22 in Figure 4 shows an opposite gear, but with its elongated cuboid gear box very voluminous is. Two flat gear boxes each having an L-shaped configuration, one of which satisfies the (non-counter-rotating) drive of the continuous drive rod and the other fulfills the implementation in an opposite movement of an extended drive rod section is known from GB 2,277,958 (Plus Plan). From GB-A 2 252 351 (Crompton) is known a cross-sectionally L-shaped gear housing, see. Figures 4 to 6, which has vertically standing drive rod pieces, which are arranged in the lower, substantially cuboid box-shaped shorter leg. Parallel to the extension of the longer leg gears are arranged, which engage in opposite rack sections and cause a reverse rotation of the drive rod sections. From the long leg of a movement on one of the drive rods is exercised via a pinion portion which is rotatably mounted there. A closer to an L-shaped flat design housing design is known from GB-A 2 289 709 (Derek King). A rotational movement is used there in an embodiment of the local figures 2 and 5 as a trigger of an opposing thrust movement of two drive rods. Arranged in the lower leg are two plate-type motion transducers which control the counterrotation of the drive rods caused by a pushing movement introduced by the other leg onto one of the drive rods. Both legs have a flat shape and in cross-section substantially the same length. As an attachment such an assembly is preferred, which is according to the local figure 2 laterally adjacent to the front side of the wing surface insert without one of the legs there on the wing surface portion over, parallel to the plane of the surface portion engages.

FR-A-2 335 678 shows in FIGS. 15 and 16 a conventional trial-type transmission with three projecting sections, one for receiving a pinion and two mounting sections on both sides of the actuating section, the housing being approximately T-shaped in cross section for control of flat drive rods next to the front end of a wing surface section.

The object of the invention is to design a counter-rotating transmission in such a way that it takes up less space and is able to work directly in the gearbox with a movement conversion.

This is achieved by a counter-rotating transmission according to claim 1, achieved with a flat in height L-gearbox. His two thighs, one long and the other short, are flat (low height). The drive rod is arranged in two parts in the short leg and a rotary converter is arranged in the same short leg of the L-gearbox. The drive of the rotary converter takes place from the long leg of the L-gearbox. The rotary converter transmits the longitudinal direction of movement of a drive rod in an opposite longitudinal movement of the other drive rod (claim 1 or 12).

In narrow profiles is often no room for the introduction of a gearbox in the profile, so that according to the invention, only the necessary transmission of the rotary motion is made from the longer leg and all other couplings or conversions can be moved into the rebate air. The short leg of this gearbox flat box is arranged pointing parallel to the end face of a wing to the rebate area, the long leg extends into the recess of the wing, which in this offset gear until behind the front end of the pane used in the frame glass as an example of a surface use enough.

On the side facing away from the axis of the actuating handle (on the long leg) side of the rotary converter transmits the opposite longitudinal movements of the two-part drive rod

The rotatorisch working converter is rotatably mounted in the short leg of the L-gearbox, preferably vertically below the axis in which the actuating handle is used for counteracting the transmission, so that both axes come to rest in a plane perpendicular to the espagnolette plane.

The transmission of the rotational movement of the actuating handle via a pinion sector, which drives the first of the two drive rails in the longitudinal direction via a linear rack section (claim 3).

In this case, the drive movement for the rotary converter can be transmitted either directly from the linear tooth piece to the rotary converter or over the Driving rod are applied indirectly. On the other side of the rotary motion converter, a comparable linear tooth piece is arranged, which converts the rotational movement of the rotary converter back into a linear movement in the opposite direction.

The linear tooth pieces may be insert parts (claim 4), which carry a linear tooth portion on the side of the rotary converter. The insert on the side of the pinion portion to the operating handle thereby has a second tooth portion on the other side of the flat insert piece; the insert on the side of the counter-acting drive rail has only one suitable for recess in the drive rail shape to exercise positively or non-positively, the movement in the longitudinal direction of the second drive rail.

If components are to be saved, two identical flat (not high) tooth pieces can be used. In another embodiment (claim 5), the tooth pieces can also be bent portions of the drive rods themselves, so that the inserts do not need to be made separately, but are an integral part of a respective drive rail.

In order to reliably couple the relatively small diameter pinion from both tooth pieces, the toothing to this rotation converter may be narrower than the toothing between the operating handle and the one of the two linear tooth pieces.

The structure in the short leg of the counter-rotating gear is in two layers in two superposed planes, the plane of the drive rails in which they work in opposite directions, and the plane of the motion converter directly below the drive rail (claim 9). On both sides of the pinion in the direction of the two drive rails can be provided a compensating piece, which can also be extended so that a continuous appearing cover rail directly below the counter-rotating drive rails results (claim 10).

The cover rail is held in the gear box, interrupted by a flat gear room in which the pinion makes the implementation of the direction of movement of a drive rod in the vicinity of the other drive rod. This space should have the height of the pinion about to allow a frictionless rotational movement, so that the strength of the pinion should be adapted to the thickness of the cover rail (claim 2).

The formation of the drive rails in the gear box is point-symmetrical to the axis of the rotary converter (claim 7). Thus, two identical drive rods can be used as opposing drive rods.

The formation of the respective end of a drive rod can be double-stage at the respective edge or edge (claim 8), wherein one of the stages in the direction of the longitudinal movement B, E allows a taper for entry into the flat leg of the gear box and the second stage on the outwardly facing side receives the flat linear tooth piece to positively apply force to move the drive rod. However, the other edge of the drive rail is stepped more clearly, so that about half of the original width of the respective drive rail is excluded to run parallel to the two drive rails in the central region of the transmission, above the flat gear space of the motion converter, so that the Half of the gearbox is covered by one and half by the other drive rail. The two drive rails engage in such a complementary manner and are extended or retracted in opposite directions by the action of the directly adjacent motion converter. The other edge also has a step of the same dimension across the first edge of the first edge. The gear box is not so side off, opposite the drive rod width.

The implementation of the rotational movement in the axis in which the operating handle is used, in the opposite longitudinal movement on the drive rod is such that after attachment of the gearbox on the wing in the fold or in the folded air, the implementation is made of the short leg or his Casing. The seaming air is the only space available for such a conversion in the case of narrow or flat airfoils and, according to the invention, this space is advantageously used to create the counter-rotation.

The assembly of the transmission according to the invention is preferably carried out in frame profiles or sash profiles made of plastic or metal and can be used both in swing wings and tilting wings with horizontal or vertical axis use.

The counter-rotating transmission according to the invention is suitable both for the use of stimuli-lying (exposed) drive rails, as well as for those who are still covered by a cover rail. Due to the small width or the small thickness of the longer leg transmission of the invention can be varied almost arbitrarily in its depth, so that it is able to place space between the surface of the frame and the front end of the wing area use. In addition, the long leg of the transmission can extend far into the frame profile, almost to the inner edge. Frame profile cavities can be filled with high fill factor, in other words, the frame profile may be flatter and less bulky.

are partial views of a cross-sectional view of the installation of the L-shaped offset gear 1 in the wing S made of plastic with an inserted glass pane E on Glasanlageabschnitt G, which wing S is not quite shown in the other.

FIG. 1a illustrates the axis 100 in which a handle is inserted into the long leg 1a of the L-shaped housing 1, which is seen in cross-section in FIG. 1b. The short leg 1b of the same flat housing can be seen in FIG. 1b a second axis 102 is provided in which a motion converter operates as a flat pinion 30. The motion converter as a rotary converter 30 can be seen in Figure 1a in its movement space shown there by recess the edge side of the short leg, the two compensating pieces 40b, 40a are clearly visible from the exploded view of Figure 2 .

The transmission will be described below without specific reference to any of the mentioned figures. The clearest result is the function in the exploded view of Figure 2 and the marked directions of movement A, B, C, D and E of the respective respective components 21, 10a, 30, 22, 10b.

Starting from a rotational movement, which is applied via the actuating lever on the sector 20 with coarse toothing, a flat insert 21 moves in a direction A, so that a first implementation of a rotational movement takes place in a linear movement. This linear movement A is received by the flat drive rod 10a to obtain a first movement component B in the one direction of locking or unlocking. With the movement of the flat tooth piece 21, the rotation converter 30 is actuated on its underside via a second toothing, which is set into a rotational movement C when the first drive rail 10a moves linearly. The rotation reaction takes place on the other side of the transmission in turn in a longitudinal movement through another flat tooth portion 22, which in the example shown has only a lower tooth area and top blunt ends to interlock positively in another drive rail 10b, which occurs during movement of the Tooth piece 22 in the direction D in the same direction E moved longitudinally. Thus, the basic motion-transfer history of the rotational movement of the operating handle on the above-mentioned five elements of the counter-rotating transmission is explained both in one direction on a drive rod 10a and in the other direction of the other drive rod 10b.

The transmission is housed in the L-shaped box, which has a flat short leg 1b and a flat long leg 1a, the overall shape being L-shaped, so that there is no overall box-shaped training, but a displacement of the long leg relative to the Axis 102 of the short leg. Perpendicular to the axis 102, which is the axis of the motion converter 30 as a pinion, lie two planes E10, E40, wherein in the one plane E40 both the pinion 30 and the two (flat) compensating pieces 40a, 40b in the short leg 1b of Flat box lie. Directly above is the plane E10, in which the drive rails 10a, 10b move in opposite directions. As can be seen in the Schitt representation of Figure 1b, the two tooth pieces 21, 22, wherein a lower second tooth piece 22 extends only in the short leg, while the other higher tooth piece 21 with arranged on both ends of its surface tooth areas in both the short leg 1b and in long leg 1a runs.

The respective angled housing plates 1a ', 1a "and 1b', 1b" are shown in Figure 2 in its essential shape, two flat housing plates 1a ', 1a "and 1b', 1b" give one of the two legs 1a, 2a of the L. Gearbox, wherein the respective longitudinal end face is covered by a further bend of the respective plate.

An explanation should still require the shape of the gradation of the drive rails 10, 10b.

They are - as seen in Figure 1a - initially weakly graded to run into the short leg of the gearbox flat box 1, wherein the width of the drive rails outside the short leg corresponds approximately to the width of the finished short leg of the gear housing. In the flat leg of the gear housing, a further gradation is provided, which ensures that two gear rods in the plane E10 come to lie next to each other and are movable in opposite directions in this plane. The second gradation, viewed from the outside inwards and at the mutually facing inner edges of the two flat bars 10a, 10b, is at least half the width of the flat bars 10a, 10b, so that the same shape is obtained for the one and the other of the two flat bars, despite different direction of movement.

At the respective outwardly facing edge of the two flat drive rods 10a, 10b, two axially successive gradations are provided; the one graduation corresponds to the previously described first gradation when entering the short leg of the flat housing, the second recess corresponds to the linear tooth piece used vertically to positively transfer the force from a rotary motion to a linear motion or vice versa.

In another, not shown embodiment, the linear tooth pieces can also be formed by bending directly and in one piece from the drive rods, so that no separate inserts are required.

The two short compensating pieces 40a, 40b may be lengthened in the longitudinal direction in such a way that it forms an outwardly of the flat leg continuous cover rail for the adjacent guided counter-rotating drive rods 10a, 10b.

Figure 3a and 3b show installation possibilities of the flat counter-rotating transmission with the long leg 1a to well behind the front end of the wing surface insert E, which will usually be a glass. The sash profile S in both representations is made of plastic and the seaming air F or the area between the fixed frame R (fixed frame) and the movable sash S receives the short leg 1b. The implementation of the rotational movement in the axis 100 not shown in these figures in an opposite longitudinal movement of drive rails 10a, 10b does not take place in the sash and not in the groove of the sash, but outside of the profile, in the rebate air area F.
