Description

DESCRIPTION

A drive

The invention relates to a drive rod gear for a window, a door or the like, for transmitting the rotational movement of a control element in a translational movement of a drive rod, with a first at least indirectly driven by the control rotatable gear segment and a second of the first gear segment second rotatable gear segment.

For locking a wing of a window, a door or the like or for a tilted position of a wing, it is known to move a drive rod via a drive rod and bring so locking elements into engagement with associated strike plates. In this case, a greater force must be applied if a locking element is in the region of a closing piece. It is therefore desirable to design the transmission so that greater torque is present when the latch is in the region of the striker.

From WO 2007/071509 Al a drive rod transmission is known, in which the introduced by means of an operating lever rotational movement is transmitted via a pivot lever to a gear, wherein the gear has a driver, which is guided in a gate of the pivot lever. The driver is mounted eccentrically on the gear. To reverse the direction of rotation, the gear meshes with another gear, which transmits the rotational movement to the drive rod. The pivot axes of the pivot lever and the gear are offset arranged to each other. By this arrangement, it is possible, on the one hand, to convert a 180 ° rotation of the control element into a larger stroke and, on the other hand, to realize a greater torque in the end regions of the movement of the control lever.

Object of the present invention is to provide a simplified espagnolette gear, which realizes a variable torque.

This object is achieved according to the invention by an espagnolette gear of the type mentioned, wherein the first gear segment is part of a first gear arrangement and the second gear segment is part of a second gear order, and wherein the gear arrangements are coupled with different translations. Characterized in that the gear arrangements are coupled with different translations with each other, different torques can be realized. Preferably, the gear assemblies are coupled together so that the drive rod travels a long way when a small force must be introduced, which usually corresponds to a rotational position of the wing, and the drive rod covers a smaller path when retracting into a strike plate or Extending a locking element should be made of a strike plate. Thus, in a smaller way, a longer gear ratio is chosen and thus a larger force is introduced. The drive rod according to the invention comes without a lever, so that the control can be coupled directly to a gear arrangement. In particular, the operating element can have a square which can engage in a corresponding inner square of a toothed wheel of one of the toothed wheel arrangements. According to a particularly preferred embodiment, it may be provided that at least one gear arrangement has two gear segments arranged one after the other in the rotational axis direction. Due to the different gear segments different translations can be realized.

It is particularly advantageous if the two gear segments of at least one gear arrangement have different radii. The two gear segments can either interact with an axially displaceable gear of the other gear arrangement, so that the gear engages either one or the other gear segment and thus different translations are realized or the other gear arrangement can also have two gear segments, wherein the gear segments of the other Gear arrangement may have the same radius. In principle, however, it is also conceivable that both gear arrangements have gear segments with different radii so as to be able to realize different ratios, depending on which gear segments of the two gear arrangements are in engagement with each other.

Preferably, the ^' gear segments of at least one gear assembly rotatably coupled together. In particular, seen in Drehachsrichtung successive gear segments rotatably coupled to each other, so lie in different planes and be arranged relative to each other non-rotatable. For example, the gear segments may be provided on two gears arranged one behind the other, which are coupled non-rotatably. The gears can be arranged coaxially. It is particularly preferred in this context if at least one gear arrangement is formed in one piece. Such a gear arrangement can be produced particularly easily, for example as an injection-molded part. This can be avoided that two gears must be connected to each other or must be applied to a common axis of rotation.

It is particularly preferred if the second gear arrangement is coupled for movement with the drive rod, in particular at least one of the gear segments engages with its teeth in corresponding openings or toothings of the drive rod. Thus, a conventional drive rod, in particular straight drive rod without bending, can be used. There are no further transmission means or drivers needed to transmit the rotational movement of the gear assembly to the drive rod.

Further advantages arise when a transmission housing is provided and at least one gear arrangement is rotatably mounted in the housing. Through the gear housing, the components of the transmission are arranged protected. In addition, the housing, in particular the housing walls, serve as bearings for the gear arrangements.

In an advantageous embodiment of the invention can be provided that in at least one gear arrangement between two gear segments of a gear tooth-free segment is formed and seen in rotational direction underlying gear has a gear segment in the tooth-free segment. This makes it possible to form the other gear arrangement without tooth-free segments, in particular in the other gear arrangement gears provided, which are fully occupied with teeth over its circumference. The described arrangement ensures that the two gear segments mesh with a gear of the other gear assembly and at the same time the underlying gear segment is not in engagement with the other gear assembly. In the region of the tooth-free segment, the gear wheel is decoupled from the associated gearwheel of the other gearwheel arrangement, and the movement coupling takes place via the gearwheel segment behind it of the gearwheel lying behind, which is then coupled to the corresponding gearwheel of the other gearwheel arrangement.

Particular advantages arise when a gear segment is arranged to be linearly movable relative to another gear segment. This allows the gear segment to be "pushed out of the way" when it is not in engagement with another gear segment of the other gear arrangement, thereby allowing a space-saving arrangement in the gear housing, so that the gear housing can take on small dimensions and thus in conventional fitting sub-grooves or Housing milling can be accommodated.

Furthermore, it can be provided that a gear of a gear arrangement with respect to the other gear rotatably and is arranged relative to this movable. Thus, an entire gear can be displaced when it is not needed to transmit the rotational movement of the operating element.

It is particularly preferred if the linearly movable gear is guided on the other gear. Through the leadership can on the one hand rotatable coupling can be realized and on the other hand the linear mobility can be ensured.

Preferably, the movable gear cooperates with a control cam of the housing. It is of course also conceivable that the

Control cam is arranged on the linearly movable gear and the

Housing a corresponding bolt or the like, in the

Control cam is guided, has. By the control curve is defined, at which time or in which rotational position, the movable gear is moved relative to the other gear.

In the context of the invention also falls a window, a door or the like with an espagnolette gear according to the invention.

Further features and advantages of the invention will become apparent from the following description of Ausführungsbespielen the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The individual features can be realized individually for themselves or for several in any combination in a variant of the invention.

Preferred embodiments of the invention are shown schematically in the drawing and are explained below with reference to the figures of the drawings. Show it:

Fig. 1 is a perspective view of a first embodiment of an espagnolette with closed housing; 2 is a perspective view of the first embodiment of the

Espagnolette, with a housing half is hidden;

Fig. 3 is a representation corresponding to Figure 2, wherein in addition to the one half of the housing also still one half of the gear arrangements has been hidden;

Fig. 7 to Figures 1 to 6 corresponding representations for a Fig. 12 second embodiment of the drive rod transmission.

1 shows a drive rod gear 1 with a two-part housing 2 with the housing parts 3, 4. By a transmission, which is arranged in the interior of the housing 2, a drive rod 5, which is arranged behind a faceplate 6, are moved. In the figure 1 is a square socket 7 can be seen, in which a not shown here operating element can be inserted. The housing 2 also has openings 8, 9, which serve as storage for gear arrangements of the espagnolette transmission 1.

In the illustration of Figure 2, the front housing part 4 s was hidden, so that now the gear assemblies 10, 11 are visible.

The gear assembly 10 includes a gear 12 with a

Gear segment 13 on. In Drehachsrichtung seen behind another gear 14 with gear segments 15, 16 is provided. The

Gears 12, 14 are rotatably coupled together and arranged coaxially lo each other. In particular, the gear assembly 10 may be formed integrally and in one piece. The gears 12, 14 and thus the gear segments 13 and 15, 16 have different radii.

The gear arrangement 11 also has a front gear 17, seen in rotational axis direction i5, with a gear segment 18 which extends over the entire circumference, and a gearwheel 19 located behind it with a gear segment 20, the gear segment 20 also extending over the entire circumference extends. The gear 17 has a smaller diameter than the gear 19. It is easily understood that the meshing of the gear segments 15 and 20 realized a different translation than the meshing of the gear segments 13, 18. The gear 19 engages with its teeth in openings 21st the drive rod 5, so as to convert a rotational movement into a translational movement. 5

The representation of Figure 2 can be seen that the control element can act directly on the gear assembly 10. In particular, the inner square 7 through the entire housing 2 and the entire gear assembly 10 extend. Thus, there is a certain amount of play for the arrangement of the operating element.

In the figure 3, the gears 12, 17 are hidden, so that the gears 14, 19 are clearly visible. Here it is particularly easy to see that the gear 14 between the gear segments 15, 16 has a tooth-free area 22. This has the consequence that in the illustrated position of the gear 14, the gear 14 does not mesh with the gear 19. In this position, only the gears 12, 17 mesh.

FIG. 4 shows a side view of the drive rod transmission 1 with the housing part 4 removed. Here it can be seen that the gear segment 15 meshes with the gear segment 20. This means that upon rotation of the first gear assembly 10 in the counterclockwise direction, the second gear assembly is set in a clockwise direction, causing a displacement of the drive rod 5 to the left. Characterized in that two gear segments 15, 20 with a relatively large diameter mesh with each other (the diameter may be equal), a first translation is realized, wherein the drive rod 5 covers a relatively small distance. It is thus realized a large torque. The gear segments 13, 18 are not engaged with each other.

The figure 4 can be further seen that the axis of rotation 23 of the gear assembly 10 is offset relative to the axis of rotation 24 of the gear assembly 11 with respect to the drive rod 5 upwards. This ensures that the gear assembly 10 does not collide with the drive rod 5. In the figure 5 the situation is shown, which occurs when the gear assembly 10 is rotated further counterclockwise. In the position shown, the gear segments 15, 20 are no longer engaged. For the gear segment 13 meshes with the gear segment 18. The gear segment 13 has a large radius, while the gear segment 18 has a small radius. Thus, although only a small force is transmitted, but the drive rod 5 sets a long way back. Thus, another translation is realized.

Upon further rotation of the gear assembly 10 in the counterclockwise direction, the situation shown in Figure 6, after which the gear segment 16 meshes with the gear segment 20 now. The gear segments 13, 18 are disengaged and do not cooperate with each other in this position. Thus, in turn, a short path of the drive rod 5 can be effected with a high force.

FIG. 7 shows an espagnolette 101 with a two-part housing 102 with the housing parts 103, 104. A drive rod 105, which is arranged behind a cuff rail 106, can be moved by means of a transmission, which is arranged inside the housing 102. The housing 102 also has openings 108, 109 which serve as a bearing for gear arrangements of the espagnolette 101.

In the figure 7 it can be seen that the housing 102 has a control cam 50 for a bolt 51. The importance of this cam 50 will be clear later. In the illustration of FIG. 8, the front housing part 104 has been hidden, so that now the gear arrangements 110, 111 are visible. The gear arrangement 110 has a gear 112 with a gear segment 113. In Drehachsrichtung seen behind another gear 114 with gear segments 115, 116 is provided. The gears 112, 114 are rotatably coupled together. The gears 112, 114 and thus the gear segments 113 and 115, 116 have different radii. The gear arrangement 110 is driven by a control element, not shown, which can be inserted into the gear 114 from the side of the housing part 103.

The gear assembly 111 also has a forward gear 117, seen in the rotational axis direction, with a gear segment 118 extending over the entire circumference and a gear wheel 119 underneath with a gear segment 120 as viewed in the rotational axis direction, the gear segment 120 also extending over the entire circumference , The gear 117 has a smaller diameter than the gear 119. It is easily understood that the meshing of the gear segments 115 and 120 implements a different gear ratio than the meshing of the gear segments 113, 118. The gear 119 engages with its teeth in openings 121 of the gear teeth Driving rod 105, thus converting a rotational movement in a translational movement

In the figure 8 it can be seen that the gear 112 has a slot 52. In the slot 52 projects a pin 53 which projects into the opening 109 of the housing part 104, for pivotal mounting of the gear assembly 110. The gear 112 is rotatably arranged with respect to the gear 114, but linearly displaceable. The displacement is effected by the driver 51 is guided in the control cam 50. If Accordingly, when the gear assembly 110 is rotated, the cam 51 moves in the cam 50, so that the gear 112 is moved relative to the gear 114. It should be noted that a movement relative to the gear 114 takes place only when the driver 51 s is in the region of the cam portion 54.

In FIG. 9, the toothed wheels 112, 117 are hidden, so that the toothed wheels 114, 119 are clearly visible. Here it is particularly easy to see that the gear 114 between the gear segments 115, 116 has a tooth-free region 122. As a result, the gear 114 does not mesh with the gear 119 at a position rotated by about 90 ° with respect to the position of the gear 114 shown. In this position, only the gears 112, 117 mesh.

It can be seen from Figure 9 that the gear 114 has a guide 55 which is straight to permit a straight linear displacement of the gears 112, 114 relative to one another. At the same time, the straight configuration of the guide 55 effects a rotationally fixed coupling of the two toothed wheels 112, 114.

FIG. 10 shows a side view of the espagnolette 101 with the housing part 104 removed. Here it can be seen that the gear segment 115 meshes with the gear segment 120. This means that upon rotation of the first gear assembly 110 5 in the counterclockwise direction, the second gear assembly is set in a clockwise direction, causing a displacement of the drive rod 105 to the left. Because two gear segments 115, 120 of relatively large diameter mesh with each other (the diameters may be the same), a first gear ratio is realized, wherein the drive rod 105 covers a relatively small distance. It is thus realized a large torque. The gear segments 113, 118 are not engaged with each other,

It can further be seen from FIG. 10 that the axis of rotation 123 of the gear arrangement 110 is offset upwards relative to the axis of rotation 124 of the gear arrangement 111 with respect to the drive rod 105. This ensures that the gear assembly 110 does not collide with the drive rod 105

In the figure 10 it can be seen that the driver 51 is in an upper position, ie in the cam portion 54. This retracted the gear 112. Thereby, the housing 102 can be made smaller, in particular with a smaller depth or lower height than in the first embodiment.

In Figure 11, the situation is shown which occurs when the gear assembly 110 is rotated further counterclockwise. In the position shown, the gear segments 115, 120 are no longer engaged with each other. For this, the gear segment 113 meshes with the gear segment 118. The gear segment 113 has a large radius, while the gear segment 118 has a small radius. Thus, although only a small force is transmitted, but the drive rod 105 sets a long way back. Thus, another translation is realized

In FIGS. 11, 12, the driver 51 is located in the region of the cam portion 57, so that the gear 112 has been displaced in order to engage with the gear 117. Is the driver located 51 in the cam portion 57, there is no relative movement of the gears 112, 114. The gear is only rotated with the driven gear 114 ₌

Upon further rotation of the gear assembly 110 in the counterclockwise direction, the situation shown in Figure 12, after which the gear segment 116 now meshes with the gear segment 120. The gear segments 113, 118 are disengaged and do not cooperate with each other in this position. Thus, in turn, a short path of the drive rod 105 can be effected with a high force.
