Description: Title: Transmission device and movable steering rod provided with such a transmission device. The present invention relates to a transmission device comprising at least two rotatable transmission components, each transmission component being provided with toothing arranged on at least part of the circumference of the transmission component, the respective toothings meshing with one another; a housing in which the transmission components are arranged; and a bearing for bearing the transmission components in the housing. A transmission device of this kind is generally known. In the known transmission device, the transmission components are formed, for example, by toothed wheels which are mounted on rotary shafts, each rotary shaft being supported with the aid of bearings provided in the housing, so that the toothed wheels can rotate with ease. A drawback of the known transmission device is that each rotary shaft has to be supported at least at two positions which are situated at a distance from one another, so that the structure is bulky and takes up a large amount of space. Moreover, it is very difficult to make the transmission device free of play. An object of the present invention is to provide a transmission device which does not have these drawbacks. To this end, the transmission device according to the invention is characterized in that at least part of the transmission components is in contact with the housing for the purpose of forming, together with the housing, the bearing, and in that means are provided for regulating, at least substantially eliminating, play between the toothings of the transmission components with respect to one another. In this way no separate bearings are required, the toothed wheel assembly can be of very compact design and a rigid toothed wheel assembly which is free of play is obtained. A transmission device with toothed transmission components is known per se from US-2 , 38 , 657. However, in this transmission device it is not possible to regulate or eliminate the play between the transmission components. Although the play between the housing and the transmission components can be eliminated, the aim of doing so is to generate a frictional force between the housing and the transmission components, so that rotation of the transmission elements is inhibited. FR-867,888 has disclosed a transmission device in which the transmission components are mounted on removable shafts . In a preferred embodiment of a transmission device according to the invention, the means for regulating the play between the toothing of the transmission components is formed by the housing, the shape of the housing being such that, if the transmission components are accommodated in the housing, the housing exerts a biasing force on the transmission components, with the result that the transmission components mesh with one another without play. In a further preferred embodiment of a transmission device according to the invention, part of the circumference of a transmission component bears against part of the inner surface of the housing. In this way, the inner surface of the housing and that part of the circumference of the transmission components which bears against the inner surface form the bearing. In another preferred embodiment of a transmission device according to the invention, the toothing of at least one transmission component extends over part of the circumference of the transmission component and the untoothed part of the circumference of the transmission component bears against the housing. The result is a larger contact area for forming the bearing, so that the transmission device is less susceptible to wear. In order to reduce the friction between the transmission components and the housing, the inner surface of the housing is preferably provided with a friction- reducing lining, for example made of plastic. Further preferred embodiments of the transmission device according to the invention are described in claims 6 - 12. The invention furthermore relates to a steering assembly, in particular bicycle handlebars, as defined in claims 13 - 29 and to a bicycle which is provided with handlebars according to the invention. The invention will be explained in more detail in the following text with reference to the attached drawing, in which: Fig. 1 is a view of a transmission device according to the invention, Fig. 2 is a view of a transmission device according to the invention in which each transmission component has an untoothed part, Fig. 3 is a view of the transmission device in accordance with Fig. 2, which is provided with adjustment means for regulating the play between the transmission components, Fig. 4 is a cross-sectional view of a transmission device according to the invention, in which the housing is provided on the inside with a lining, Fig. 5 is a view, partially in section, of a transmission device according to the invention, in which the housing comprises two housing halves, Fig. 6 is a view, partially in section, of another embodiment of a transmission device according to the invention, in which one transmission component partially tapers, Fig. 7 is a view, partially in section, of a transmission device according to the invention, in which both transmission components taper, Fig. 8 is cross-sectional view on line I-I in Fig. 9 of a transmission device according to the invention with conical bearing faces, the transmission device being arranged in a movable steering assembly, Fig. 9 is a plan view of the transmission device of Fig 8, in which the top half of the housing has been removed, Fig. 10 is a plan view of the transmission device of Fig. 8, in which a spacer is arranged between the transmission components, Fig. 11 is a diagrammatic depiction, partially in section, of a movable steering assembly which is provided with a transmission device according to the invention, Fig. 11a is a view, partially in section, of the transmission device with blocking mechanism of Fig. 11, Fig. 12 is a view, partially in section, of a transmission device which is arranged in a movable steering assembly and is provided with a blocking device, Fig. 13 is a bottom view of the steering assembly of Fig. 12, Fig. 14 shows another embodiment of a blocking device, Fig. 15 is a plan view of another embodiment of a blocking device, Fig. 16 is a plan view of a movable steering assembly in the wide position with arm supports arranged on the transmission components, Fig. 17 is a plan view of the steering assembly of Fig. 16 which has been rotated into a narrow position, Fig. 18 is a view, partially in section, of a movable steering assembly attached to a steering-pivot pin, in which the steering assembly is attached rotatably to the steering-pivot pin and the handlebar parts are attached rotatably to the associated transmission components, and Fig. 19 is a side view of the steering assembly of Fig. 18 in a number of positions. Fig. 1 shows a preferred embodiment of a trans- mission device according to the invention. Two transmission components, in the form of toothed wheels 2, 3, are arranged in a housing 1, so as to form a toothed-wheel assembly. Each toothed wheel 2, 3 has toothing 4, 5 on its circumference. The toothings 4, 5 mesh with one another. In the exemplary embodiment in question, the housing 1 comprises a band which surrounds the circumference of the toothed wheels 2, 3, so that a rigid structure is obtained. The toothed wheels bear, over an angle of 180°, against the inside of the housing 1. The contact area between the toothing 4, 5 of the toothed wheels 2, 3 and the inside of the housing 1 forms a sliding-contact bearing which allows the toothed wheels 2 , 3 to rotate in the housing 1. The toothed wheels 2, 3 are fixedly connected to shafts 6, 7 which can be connected to drive means and/or components to be driven . Fig. 2 shows a toothed wheel assembly with toothed wheels 8, 9, the toothing 10, 11 of which extends over part of the circumference. An untoothed part 12, 13 of each toothed wheel 8, 9 bears against the inside of the housing 1. The contact area between the toothed wheels 8, 9 and the housing 1 is increased in this way. The toothed wheels 8, 9 of the toothed wheel assembly of Fig. 2 can rotate through a limited angle, which angle corresponds to the length of the toothing on the circumference of the toothed wheels 8, 9. This toothed wheel assembly is suitable in particular for the synchronization of a rotational movement through a limited angle of two components which are connected to the toothed wheels 8, 9. In order to facilitate mounting of the toothed wheels 8, 9 and to be able to eliminate play between the toothing of the toothed wheels 8, 9, which is caused by wear to the toothed wheels 8, 9 and between the toothed wheels 8, 9 and the housing 1, in a preferred embodiment of the toothed wheel assembly according to the invention as illustrated in Fig. 3 two flanged edges 14, 15 are provided, between which a gap is formed. The flanged edges 14, 15 can be moved towards one another by means of a bolt 16 and a nut 17, thus allowing play between the toothing of the toothed wheels 8, 9 and, at the same time, between the toothed wheels 8, 9 and the housing 1 to be eliminated. In this way, it is possible to allow the toothed wheels to mesh with one another without play and without the forces exerted on the toothing exceeding predetermined values . The toothed wheel assembly according to the invention in this way forms a very rigid and compact transmission. In order to improve the sliding properties between the toothed wheels 2, 3, 8, 9 and the housing 1, a lining 45 may be provided on the inside of the housing 1 at the location of the contact surface between the toothed wheels 2, 3, 8, 9 and the housing 1. The lining 45 may be a plastic lining, for example a teflon lining. In the case of toothed wheels 8, 9 with an untoothed part 12, 13, the frictional resistance between the toothed wheels 8, 9 and the housing 1 can also be reduced by providing rolling bearings at the location of the contact surface between the toothed wheels 8, 9 and the housing 1. If it is necessary to accommodate the toothed wheels in a closed housing, the housing may be formed by two housing halves la, lb, which can be pushed over the toothed wheels in the radial direction (cf . Fig. 5) . Each housing half la, lb is provided with a flanged edge 14a, 15a. A flexible seal 44 is positioned between the flanged edges 14a, 15a. The housing halves are drawn together by means of bolts 16a, 16b which project through the flanged edges 14a, 14b. Cutouts, through which the shafts 6, 7 project, are provided in the housing for the shafts 6, 7. The dimensions of the toothed wheel assembly according to the invention are defined in the radial direction by the diameter of the constituent toothed wheels and in the axial direction by the forces which have to be transmitted by the toothing of one toothed wheel to the toothing of the other toothed wheel. When the toothed wheel assembly is used for synchronizing the rotational movement of two independent components, the forces can be disregarded and the toothed wheel assembly may be of very compact design. In another preferred embodiment of a toothed wheel assembly according to the invention as depicted in Fig. 6, one of the toothed wheels tapers over part of the circumference. The untoothed part 13 of the toothed wheel 19 tapers. At the location of the contact surface between the toothed wheel 9 and the housing 1, the housing 1 is of complementary form. With the aid of bolt 18, the toothed wheel 9 is pulled into the housing 1 until the toothings 10, 11 mesh with one another without play. The toothed wheel 9 is held in the housing 1 under a predetermined and controllable ω LO to t H LΠ o LΠ o LΠ o LΠ — o — toothing, which may lead to fracture. In order to prevent this, the toothed part of the toothed wheels may be omitted in the region of the axial ends and replaced by a substantially cylindrical part, so that a spacer 28 can be provided in the region of the axial ends of the toothed wheels (cf . Fig. 10) . As a result, it is possible to set the distance between the toothed wheels with a high level of accuracy. Fig. 11 shows a set of bicycle handlebars 29, each half of which can rotate about a corresponding axis of rotation 32, 33. In order to provide synchronous rotational movement of the handlebar halves 30, 31, a toothed wheel assembly according to the invention is arranged between the two handlebar halves 30, 31. The axes of the toothed wheels 22, 23 coincide with the axes of rotation 32, 33 of the handlebar halves 30, 31. In order to be able to hold the handlebar halves 30, 31 in predetermined positions, a blocking device is provided. Moreover, the blocking device prevents the handlebar halves from moving unexpectedly into a position which is not intended by the cyclist. The blocking device as illustrated in Fig. 11a comprises an arm 34 which is fixedly connected to the toothed wheel 22. A locking element 35, which can pivot about a pivot pin 34a which is substantially perpendicular to the axis of rotation 32 is arranged at the free end of the arm 34. On the side remote from the toothed wheel 22, the locking element 35 has toothing. By means of the toothing, the locking element 35 can mesh with toothing of an insertion element 36 which is fixedly connected to the housing 1. The locking element 35 can be moved out of the locking position with the aid of a cable 37, which is connected to an actuation button 38 via a lever mechanism. The handlebar halves 30, 31 can now be moved to a different position and, when the actuating button 38 is released, can be blocked and retained in this position. The locking element 35 meshes with the insertion element 36 with the aid of a restoring spring (not shown) . The cable 37 runs via a bore in the toothed wheel 22 and the inside of the handlebar half 30 to the actuating button 38. It is also possible for the locking element 35 to mesh directly with the toothing of one of the toothed wheels. The arm 34 is then fixedly connected to the housing 1. Fig. 12 shows another blocking device which is suitable for use in the toothed wheel assembly according to the invention. A locking element 39 is rotatably attached to the toothed wheel 23, the axis of rotation being coaxial with the axis of rotation of the toothed wheel 23. On the axial side of the toothed wheel 22, which lies in the same plane as the axial side of the toothed wheel 23 to which the locking element 39 is attached, an insertion element 40 is fixedly connected to the toothed wheel 22. As illustrated in Fig. 12, the locking element 40 is integral with a pin which is connected coaxially and fixedly to the toothed wheel 22. The locking element 40 is substantially fan-shaped. On the side facing the locking element 39, the insertion element 40 has a number of recesses. The locking element 39 has a projection 41, the shape of which corresponds to the shape of the recesses. In this embodiment, the handlebar halves 30, 31 can be blocked in four different positions. The projection 41 can be pulled out of the recess in question with the aid of the cable 37, after which the handlebars can be adjusted to a different position. The projection 41 and the recesses in the insertion element 40 are shaped in such a manner that rotation of the two handlebar halves 30, 31 in one direction is blocked. By exerting a force on the handlebar halves 30, 31 in the other direction, the projection 41 is forced out of the recess in question due to the fact that one side of the recess in question and/or of the projection 41 is chamfered, and the handlebars can be moved to a different position. This continues until a limit position is reached. The handlebars can then only be restored to the original starting position by removing the projection out of the recess which defines the limit position with the aid of the cable 37, so that the handlebar halves 30, 31 can rotate freely.

The toothed wheel assembly according to the invention is particularly suitable for use in a movable set of bicycle handlebars which has to be lockable in two positions. The first position is a folded-out position which forms bicycle handlebars which are comparable to conventional handlebars. In the second position, the two handlebar halves are rotated towards one another as far as possible. The handlebar halves are preferably rotated in a direction in such a way that the free ends of the handlebar halves in the second position are situated next to one another and directed towards one another. This reduces the space taken up by a bicycle which is provided with movable handlebars of this kind and in which the movable handlebars have been placed in the second position. This is advantageous in particular for storing the bicycle in a bicycle shed. Fig. 16 shows another embodiment of handlebars which are provided with a toothed wheel assembly according to the invention. The handlebar halves can be rotated forwards, so that the handlebars are made narrower and the cyclist can reach further forwards. This provides a more aerodynamic and sporting position. Two shafts 46, 47 which are fixedly connected to the relevant toothed wheels project through openings in the housing 1, an arm 48, 49 being attached to each free end of the shafts 46, 47. A support component 50, 51 is arranged adjustably on each arm 48, 49. In the forward position of the handlebar halves, the cyclist can support himself with his forearms on the support components 50, 51. In the wide position of the handlebars, the support components 50, 51 are rotated against one another, so that the cyclist can place his hands against the housing. In the forward position of the handlebar halves (Fig. 17) , the support arms 48, 49 are rotated laterally outwards, thus positioning the support components 50, 51 at a width which is such that the cyclist can comfortably place his forearms on the support components 50, 51.
