Abstract

The invention relates to a gear arrangement for driving a sliding bar, comprising a drive element (1) for coupling to an actuating member and an output element (2a, 2b) for coupling to the sliding bar. The drive element (1) and output element (2a, 2b) are coupled in such a way that a back and forth rotation of the drive element (1) about an axis of rotation (X) produces a translational forward and backward movement of the output element (2a, 2b). The coupling comprises a transmission member (3a, 3b) which is pivoted during the rotation of the drive element (1), having a first coupling point or region (4a, 4b) via which a drive force is introduced into the transmission member (3a, 3b) during the rotation of the drive element (1), and having a second coupling point or region (5a, 5b) via which an output force is channelled from the transmission member (3a, 3b) to the output element (2a, 2b) during the rotation of the drive element (1). During the pivoting of the transmission member (3a, 3b), the second coupling point or region (5a, 5b) covers a greater movement path than the first coupling point or region (4a, 4b), and the transmission member (3a, 3b) is pivoted about a pivot axis (Ya, Yb) which extends perpendicularly to the axis of rotation (X) of the drive element (1), or is pivoted along a pivoting path which lies in a plane which extends parallel to the axis of rotation (X) of the drive element (1). The embodiment according to the invention of the gear arrangement means that it is possible for the latter to be designed to be extremely narrow, with the result that it can also be used in window sashes and glazed doors having very narrow frame profiles.

Description

Gear arrangement for driving a sliding latch

TECHNICAL AREA

The invention relates to a gear arrangement for driving at least one sliding latch, in particular a door or a window, and a door or window sash with the gear arrangement according to the preambles of the independent claims. STATE OF THE ART

Gear arrangements for driving sliding bars are used in building and cabinet doors as well as in window sashes, in particular when the door or window is to be actuated in several places by a single actuating element, usually in the form of an actuating handle or a key to lock.

The gear arrangements according to the invention known from the prior art have a relatively large width in the direction of the flat extension of the door leaf or window sash, for which reason they are mounted on the door leaf or the frame of the window sash or, in the case of them be invisible, be embedded in the door leaf or the frame of the window sash.

Such gear arrangements are known, for example, from the documents EP 0 182 751 A1 and DE 10 2009 061 132 B3.

Apart from the fact that at least the invisible assembly of these known gear arrangements is associated with a great manufacturing effort, there is also the disadvantage that a use of such gear arrangements, whether hidden or visible, with window sashes and door leaves with glazing a correspondingly wide Frame profile, which is why, in particular, for window sashes with narrow Rahraenprofilen a use of such gear arrangements is not possible until now.

PRESENTATION OF THE INVENTION

It is therefore the object to provide a technical solution that does not have the aforementioned disadvantages of the prior art or at least partially avoids.

This object is solved by the subject matter of claim 1.

This relates to a transmission arrangement for

Driving at least one sliding latch, preferably a building or cabinet door or a window.

The gear arrangement comprises a drive element, e.g. in the form of a drive shaft, for coupling to an actuating member, such as an operating handle or a key. Furthermore, the gearbox arrangement comprises at least one output element for direct or indirect coupling, e.g. via a push rod, to at least one sliding bolt.

The drive element and the at least one

Output elements are coupled to one another such that a rotation of the drive element in a first direction of rotation about a rotational axis causes a translatory movement of the at least one output element in a first shift direction and a twisting of the drive element in an opposite (correspondingly second) direction of rotation a translational movement of the at least one output element in an opposite (according to the second) displacement direction is effected around the axis of rotation.

The coupling between the drive element and the at least one output element takes place with the use of at least one pivotable transmission element, such as a lever, which pivots about a rotation axis about a pivot axis or along a pivot path when the drive element rotates about the axis of rotation and which has a first coupling point or coupling region, via which a driving force is introduced into the transmission element when the drive element is rotated, and has a second coupling point or coupling region, over which an output force from the transmission element at least turns when the drive element is rotated an output element is passed, wherein the coupling is designed such that the second coupling point or coupling region of the at least one transmission member when pivoting the same sets a greater path than its first coupling point or coupling region.

According to the invention, the coupling is also configured in such a way that the at least one transmission member is pivoted about a pivot axis about its pivot axis which is perpendicular to the axis of rotation of the drive element or is pivoted along a pivot path which is in one plane which runs parallel to the axis of rotation of the drive element.

In other words, the first aspect of the invention thus relates to a gear arrangement for driving a sliding bolt, comprising a drive element for coupling to an actuating member and a drive element for coupling to the sliding bolt. The

The drive element and the output element are coupled in such a way that a back and forth rotation of the drive element about a rotational axis causes a translational forward and backward movement of the output element. The coupling of drive element and output element comprises a translation element, which is pivoted when the drive element is rotated. This has a first coupling point or region, via which a driving force is introduced into the transmission element when the drive element is rotated, and has a second coupling point or region over which rotation of the drive element an output force from the translation organ is passed to the output element. The second coupling point or region, when the displacement member is pivoted, travels a greater distance of travel than the first coupling point or region, and the transmission member is pivoted about a pivot axis which is perpendicular to the axis of rotation of the drive element. or is pivoted along a Verschwenkbahn, which lies in a plane which is parallel to the axis of rotation of the drive element.

Due to the inventive design of the gear assembly, it is possible to make them extremely narrow, so that they can be used even with casements and glazed doors with very narrow frame profiles.

Preferably, several output elements are present for coupling to a plurality of sliding latches, preferably exactly two. Such gear arrangements enable multi-point locking of a window equipped therewith or of a door equipped therewith, which is often desirable for safety-related considerations as well as for reasons of uniform, precise closure.

In this case, the output elements can each be coupled to the drive element via a separate transmission element or, as a whole, via a common transmission element or in groups via common transmission elements. Depending on the design of the gear arrangement and the direction of movement of the output elements, one or the other variant may be particularly advantageous.

Particularly preferred embodiments of the gear arrangement have exactly two output elements, which can be moved by turning the drive element in opposite directions. Such gear arrangements enable a conventional two-point locking of a door or window wing equipped therewith. In a further preferred embodiment of the gear arrangement, the one or more Übersetzungsorga- ne as pivoting levers are formed, which are pivotable about a stationary pivot axis around. Such a design is simple and inexpensive to manufacture.

In yet another preferred embodiment of the gear arrangement, the drive element has a pinion or gear element.

This meshes according to a first advantageous variant in at least one associated toothing, which is formed by the first coupling region of the at least one transmission element.

According to a second advantageous variant, the pinion or toothed wheel element of the drive element meshes in at least one associated gearing which is formed by at least one coupling element which is displaceable or pivotable in a plane perpendicular to the pivot axis of the at least one transmission element and runs parallel to the axis of rotation of the drive element, and which is coupled directly or indirectly to the first coupling point or the first coupling region of the at least one transmission element.

Preferably, in both variants, the at least one toothing, in which the pinion or toothed wheel element of the drive element meshes, a flat toothing, which extends in a plane which extends parallel to the axis of rotation of the drive element. As a result, particularly narrow gear arrangements according to the invention become possible.

While the first advantageous variant can be implemented particularly cost-effectively with few moving parts, the second advantageous variant provides greater freedom of design with regard to the spatial arrangement of the components and the power transmission within the gear arrangement. In particular, in the second variant, various preferred subvariants are provided.

Thus, it is further preferred, for example, for a plurality of output elements to be present, each of which is coupled to the drive element via its own transmission element, wherein each of the transmission elements is coupled to the drive element via its own coupling element.

It is also advantageous that the one or more coupling members is or are displaceable in a plane which is perpendicular to the pivot axis of the at least one transmission member and parallel to the axis of rotation of the drive element. This favors a particularly narrow construction of the gearbox arrangement according to the invention.

Furthermore, it is preferred that the coupling member or the coupling members is or are coupled directly to the first coupling point or coupling region of the respective transmission element directly via a coupling pin or toothing. In this way, the coupling can be realized easily and inexpensively.

Furthermore, it is preferred that the transmission elements or the coupling members, which form the preferably flat toothings in which the pinion or gear element of the drive element meshes, are each formed as a plate-shaped component.

In a first preferred variant, the toothing penetrates at least half of the plate thickness into the plate-shaped component from the plate side facing the pinion or gear element, advantageously at least up to three quarters of the plate thickness. This measure also favors a narrow construction of the inventive gear arrangement.

In this case, stand the or the transmission members or the coupling or the respective organs in the region of the toothing in a direction transverse to the extent of the Teeth of the toothing seen on one or both sides on the pinion or gear element of the drive element, and has this or have them in this direction in a cross section through one of the groove foundations of the toothing in the protruding areas at least in sections a greater thickness than in the region of the meshing of the pinion or Zahnradele- ment, so the teeth can penetrate the plate-shaped component even almost completely, since the Zahngrundgrund must make no contribution to the stability of the plate-shaped component.

Accordingly, in a second preferred variant, the toothing penetrates the plate-shaped component. In this case, in the region of the toothing in a direction transverse to the extension of the teeth of the toothing, the plate-shaped component projects on one or both sides via the meshing pinion or toothed wheel element of the drive element with regions in which it does not extend the interlocking is penetrated. Correspondingly, in this variant, the toothing in which the pinion or gear element of the drive element meshes essentially consist of openings in the plate-shaped component. In this way, the toothing in the plate-shaped component can be produced in a particularly cost-effective manner, e.g. by punching, and it is a particularly narrow construction of the inventive gear assembly possible.

In yet another preferred embodiment of the transmission arrangement according to the invention, the output element (s) are coupled directly to the second coupling point or coupling region of the respective transmission element via a coupling pin or a toothing. In this way, the coupling can be realized easily and inexpensively.

It is further preferred that the output element or elements of the inventive gear arrangement are each formed as a plate-shaped component and in the pivoting plane of the respective. Translation member or in a plane parallel thereto perpendicular to the rotational axis of the drive element are displaceable.

If the transmission arrangement according to the invention has a plurality of output elements, then it is advantageous if these are each coupled to the drive element in an identical manner. This makes it possible to reduce the number of different components required for the production of the gear arrangement, and thus the production costs.

A second aspect of the invention relates to a door or window wing, comprising a gear arrangement according to the first aspect of the invention for actuating one or more sliding bars for locking the door or the window. In such objects, the advantages of the invention are particularly evident.

FIGS. 1 and 2 show top perspective views of a gearbox arrangement according to the invention, once with retracted latching tabs 2a, 2b (FIG. 1) and once with advanced latching tabs 2a, 2b (FIG. 2).

Fig. 3 shows a perspective top view from below of the gear assembly with retracted locking tabs 2a, 2b and Fig. 4 shows a side view of the gear assembly.

FIGS. 5 and 6 show a longitudinal section through the gear arrangement along the line A-A in FIG. 4 (FIG. 5) and an exploded view of the gear arrangement (FIG. 6), in which its individual parts can be seen.

As can be seen, the moving components 1, 2a, 2b, 3a, 3b, 8a, 8b of the gear arrangement are arranged in an elongated metal housing, which is formed from two housing half-shells 11, 12. The moving parts are made of metal.

The gear arrangement has a four-edged

Drive shaft 1 on (claim according to the drive element), by means of which by turning the same relative to the housing 11, 12 two locking tabs 2a, 2b (demanding driven elements) projecting out of the housing at the two housing ends can be selectively brought into a maximally retracted position ( see FIG. 1) or can be brought into a maximally advanced position (see FIG. 2). For maximum retraction of the locking tabs 2 a, 2 b in the withdrawal direction S2, the drive shaft 1 is rotated counterclockwise by 90 °, starting from the situation illustrated in FIG. 2 (direction of rotation D 2 according to the requirements), for maximum advancement of the locking tabs 2 a, 2 b in FIG Feed direction Sl, the drive shaft 1 is rotated starting from the situation shown in Fig. 1 by 90 ° clockwise (claimed direction of rotation Dl). As in particular from a synopsis of

Figures 5 and 6 can be seen, the drive shaft 1 forms at its arranged in the housing 11, 12 end of a gear 6, which in planar toothing sections 7a, 7b, of two each disposed between one of the housing shells 11, 12 and the gear 6 plate bodies 8a, 8b (complex excipients) meshes. The plate bodies 8a, 8b are axially displaceable in guide pockets 13a, 13b in the respective housing shell 11, 12 in a plane which is parallel to the axis of rotation (X) of the drive element (1), and in the longitudinal direction of the housing 11, 12 or Shifting direction Sl, S2 of the locking tabs 2a, 2b out. The retraction and feed directions S1 and S2 and the directions of rotation D1 and D2 are shown in FIG.

The axial displacement of the plate bodies 8a, 8b in the guide pockets 13a, 13b caused by the rotation of the drive shaft 1 via the engagement of the toothed wheel 6 in the toothed portions 7a, 7b of the plate bodies 8a, 8b is transferred respectively to a pivoting lever 3a, 3b (according to the claims Translation member), which is pivoted by the axial displacement of the respective plate body 8a, 8b about a stationary end-side pivot axis Ya, Yb, which is perpendicular to the axis of rotation X of the drive shaft 1.

The coupling between the respective plate body 8a, 8b and the respective pivoting lever 3a, 3b is effected via a coupling pin 9a formed at a location 4a, 4b between the ends of the pivoting lever (demanding first coupling point) on the pivot lever 3a, 3b, 9b, which engages in a slot-shaped driving opening 14a, 14b in the respective plate body 8a, 8b.

The Schwenkhhebel 3a, 3b in turn drive by their pivotal movement in each case one of the two Rie- tabs 2a, 2b, which are mounted axially displaceable in their displacement directions Sl and S2 in the housing 11, 12 by their inwardly directed ends in leadership ungestaschen 15a, 15b are guided in the lower housing shell 11 and they each have in their central region a slot 16 which is penetrated by a formed on the upper housing shell 12 guide sleeve 17.

The coupling between the respective pivoting levers 3a, 3b and the locking lug 2a, 2b takes place via a coupling pin 10a, 10b formed on the pivoting end 5a, 5b of the pivoting lever (according to the requirements of the second coupling point) which engages in a slot-shaped driving opening 18a, 18b in FIG the respective latch tab 2a, 2b engages.

As can also be seen, the toothing 7a, 7b penetrates practically completely into the respective plate body 8a, 8b in each case in the region in which the toothed wheel 6 meshes therein. In order to achieve sufficient stability, the groove bottoms of the respective toothing 7a, 7b run out into the outer surface of the respective plate body 8a, 8b in the edge regions in which it is not in engagement with the toothed wheel 6, so that in the Edge regions virtually no weakening by the teeth 7a, 7b is.

While preferred embodiments of the invention are described in the present application, it should be clearly understood that the invention is not limited to these and may be practiced otherwise within the scope of the following claims.
