TECHNICAL FIELD OF THE INVENTION The invention relates to a device for turning a scooter, but also to the scooters comprising such a device, as well as to a device for reversing a scooter. 'to the processes of turning these draisines. State of the art Pipes are light vehicles driving on railway rails, and can be motorized or not. For example, they can be used for track maintenance or used in a tourist setting. This is the case of cyclo-rail cars, or bike-rails that are vehicles propelled mechanically on a railway track by the pedaling effort of its users. The cyclo-draisines are used on abandoned roads, in order to discover landscapes and works of art very often inaccessible by another means of transport. Since they are on rails, the cyclo-draisines can not turn around as easily as a conventional vehicle. This operation can be performed by carrying the device, but this can be difficult because of the weight and size of the cyclo-draisine. This operation can be complex if the task is up to the users themselves, who must be several to perform the operation.

According to an alternative embodiment, the trolley comprises: - a frame, 30 - a pivot point having an end movable in rotation, fixed under the frame.

The invention also relates to methods for reversing the pigments having the above characteristics.

When the trainer includes a turning device, the method may comprise the following steps: - providing a pivot point having a rotatable end, - rolling the car along a railroad rail so that the the rotatable end of the pivot point engages along the ramp to the plate, so as to lift the stick on at least two wheels of an axle, - make a half-turn of the cyclo-draisine - Roll the moving end in rotation along the ramp until the cyclo-draisine on the rails of railroad.

When the car has a rotatable pivot point in rotation, the method may comprise the following steps: providing a turning device having the aforementioned characteristics, the ramp being fixed along the longitudinal axis of the railway rails of such so that in the direction of the march of the cyclo-draisine, the cyclo-draisine meets first the second end of the ramp, - to roll the cyclo-draisine along a rail of railroad so that l the rotatable end of the pivot point engages along the ramp to the plate, so as to raise the cyclo-draisine on at least two wheels of an axle, - to make a half-turn of the cyclo -draisine, - roll the mobile end in rotation along the ramp until you put the cyclo-draisine on the rails of railroad.

Other advantages and features will become more clearly apparent from the following description of particular embodiments of the invention given by way of nonlimiting example and represented in the accompanying drawings, in which: Figure 1 schematically illustrates a sectional view of a cyclo-draisin according to a first embodiment; FIGS. 2 and 3 show details of ramp attachments on the cyclo-draisine; FIG. 4 diagrammatically illustrates a detail of operation of the cyclo-draisine turning-over kit.

DETAILED DESCRIPTION A cyclo-draisin such as that shown in FIG. 1 is a vehicle for traveling along railway rails while pedaling. The dimensions are of the order of 1.5 m in width, and of the order of 2 m in length. This makes it a cumbersome heavy vehicle, and unwieldy when it comes to making him turn around. To remedy this problem, a reversal device 2 of cyclodraisin 1 can be used. This device 2 comprises a ramp 3 with 25 lateral edges, and a plate 4 also comprising lateral edges. The plate 4 is advantageously fixed to a first end 3a of the ramp 3, for example by welding or with fasteners such as screws or rivets.

The ramp 3 and the plate 4 advantageously form an obtuse angle so that a pivot point 5 (see Fig. 4) can slide from one to the other, as will be seen later. According to the embodiment illustrated in the figures, the plate 4 is located in the extension of the ramp 3, and thus the angle formed by the ramp 3 and the plate 4 is 180 degrees.

The turning device 2 further comprises hooking means 6 of the ramp 3 and / or the plate 4, either to the cyclo-draisin 1 or to the railroad. The device 2 must indeed be firmly attached to one or the other to be able to support the weight of the cyclo-draisin 1 without bending. The attachment means 6 may, however, include hinge-type links to limit the size of the device 2 when it is not used. Depending on where the device 2 is fixed, this allows for example to lay the device 2 along the railway, or to fold the device 2 against the chassis 1 a of cyclo-draisin 1.

According to a particular embodiment of the turning device 2, the ramp 3 may comprise an insertion notch (not shown) at a second end 3b. Its role is to facilitate the insertion of a pivot point 5 in the ramp 3, without having to raise the cyclo-draisin 1.

The insertion notch may, for example, be an opening placed along the longitudinal axis of the ramp 3. It may also be associated with a lateral narrowing of the ramp 3 making it possible to avoid inadvertent disengagement of the pivot point 5 in the ramp 3.

The overturning device 2 of the cyclo-draisin 1 makes it possible to significantly reduce the efforts made by those in charge of reversing the cyclo-draisin. It can also meet operating constraints, related, for example, to safety standards or to the dimensions of the cyclo-draisine 1. In order to compromise between these two requirements, the ramp 3 can be arranged so that its slope is between 10 and 3036082 6 30 ° relative to a horizontal plane may be either the chassis of the cyclo-draisine 1 or the railway itself. Furthermore, to facilitate the overturning of cyclo-draisin 1, the plate 45 may comprise a shoulder 7 (see FIGS 2 and 4) making it possible to wedge the pivot point 5 on the plate 4 when the turning maneuver is performed. Cyclo-Draisin 1 can then be rotated safely. According to an alternative embodiment, the turning device 2 may comprise two ramps 3 diametrically opposed and connected to the plate 4. This embodiment is particularly advantageous when the turning device 2 is mounted on a cyclo-draisine 1. Indeed , the device 2 15 can be mounted along the longitudinal axis of the cyclo-draisin 1, a first ramp 3 being located in the front half of the cyclo-draisin 1 and a second ramp 3 being located in the rear half. The first ramp 3 is used to raise the cyclo-draisin 1 on the plate 4 to return it, and a second ramp 3 is used to make it down after having made a U-turn. The turning device 2 can not operate without pivot point 5. Also, the assembly comprising the turning device 2 and the pivot point 5 forms a reversal kit of a cyclo-draisine 1. When the device 2 is placed on the cyclo-draisine 1, the pivot point 5 is arranged on the railway. Conversely, when the device 2 is placed on the railway, the pivot point 5 is fixed on the cyclo-draisine 1. The pivot point 5 is a member rotatably mounted on a support.

This element may for example be a wheel of fixed axis mounted on the support, and whose dimensions are adapted to those of the ramp, so that the wheel can move along the ramp 3 to reach As an alternative, the pivot point 5 may be a ball joint mounted on the support. If the plate 4 has a shoulder 7, the position of the latter is then judiciously chosen to wedge the wheel or the ball.

When the turning device 2 is mounted on the cyclo-draisin 1, the support may for example be a tripod fixed to the railway in a zone provided for the overturning of the cyclo-draisin 1. If the turning device 2 comprises a single ramp 3, it is necessary that the support 10 can be lying on the railway to allow the passage of the cyclo-draisin 1 after its U-turn, otherwise the pivot point 5 block the passage of the cyclone trolling 1. Hinge connections between the railway and the support may be provided for this purpose.

On the other hand, if the turning device 2 comprises two ramps 3, the support can be fixed on the railroad track. Indeed, since a first ramp 3 acts as a climb ramp and a second ramp 3 acts as ramp down, cyclo-rail 1 is directly in the right position after being returned.

If the pivot point 5 is mounted on the cyclo-draisin 1, its support may for example be a rod fixed on the underside of the frame 1a, possibly associated with a hinge to fold the pivot point 5 when n is not used.

As mentioned above, cyclo-draisin 1 can be carried out in different ways. According to a first embodiment, the cyclo-draisin 1 may comprise a turning device 2 as just described. In this case, the turning device 2 is advantageously fixed under the chassis 1a with the aid of the attachment means 6 along the longitudinal axis of the cyclo-draisine 1. In this case, the attachment means 6 preferably comprise a first element 6a situated at the first end 3a of the ramp 3, and a second element 6b located at the second end 3b of the ramp 3. The ramp may be positioned either in the front half of the cyclone the first element 6a is larger than the second element 6b, so that the ramp 3 has a slope of between 10 and 30 degrees. Given the dimensions of the cyclo-draisin 1, the frame 1a and the plate 4 are preferably separated by a distance of between 5 and 20 cm. According to a particular embodiment, the first and second elements 6a and 6b may each comprise a hinge connection, so as to reduce the slope of the ramp 3 when it is not used.

This may be advantageous for example in order to meet the space requirements of the turning device 2. When the turning device 2 comprises two ramps 3, a first ramp 3 is located in the front half and a second ramp 3 is located. in the back half. The two ramps are connected to the plate 4 and are fixed by means of attachment means 6. In this embodiment, the attachment means 6 may comprise jaws configured to allow the ramps 3 to slide, so as to reduce their slopes and limit the size of the overturning device 2 when not in use. Furthermore, the turning device 2 can be fixed so that the plate 4 is located along an axis orthogonal to the longitudinal axis of the cyclo-draisin 1 passing through the center of gravity of the latter. By arranging the plate 4 there, the effort required to roll over the cyclo-draisin 1 is minimal. If the plate 4 is located outside this zone, the cyclo-draisin 1 is not in equilibrium on the plate 4 when it is turned over, and the effort to be supplied is greater. According to an alternative embodiment (embodiment not shown), the cyclo-draisin 1 may comprise a pivot point 5. This comprises a support fixed under the chassis 1a of cyclo-draisin 1, on which is mounted a rotating member such as a wheel or a ball. The distance separating the frame 1a from the movable member in rotation can be between 5 and 20 cm when the pivot point 5 is in use. When the latter is not used, it is possible to reduce this distance, for example by using a support provided with a hinge. The pivot point 5 may preferably be located on an axis orthogonal to the longitudinal axis and passing through the center of gravity of the cyclo-draisin 1. As for the first embodiment of the cyclo-draisin 1, this allows to limit the efforts necessary to perform the reversal of cyclo-draisin 1.

The reversal process of a cyclo-draisin 1 can be carried out in different ways according to the embodiment of cyclo-draisin 1. When the cyclo-draisin 1 is provided with the overturning device 2, it is necessary to have a pivot point 5 positioned on the railway. The latter 25 can be fixed in order to guarantee the solidity of the supports of the pivot point 5 during the overturning of the cyclo-draisin 1. If the turning device 2 has only one ramp 3, the pivot point 5 can be removable, or hinged to be folded against the railway to allow the passage of the cyclo-draisine 1.

The pivot point 5 can also consist of a tripod which can be moved, and which can for example be loaded on the cyclo-draisine 1. In this case it is important to set the pivot point 5 so as to stable on the railway when it is necessary to return the cyclo-draisine 1.

To return a scooter 1 comprising a turning device 2 with a single ramp 3, several operations are performed. First, it is necessary to provide a pivot point 5 such as those just described.

If ramp 3 is located on the front half of the cyclo-draisin 1, the pivot point 5 must be placed in front of the cyclo-draisine 1. The latter is then moved forward along the railroad track. until the pivotally movable end of the pivot point 5 engages along the ramp 3. The pivot point is then moved to the tray 4, so as to raise the cyclo-draisin 1 on at least two wheels of one of the axles. The cyclo-draisin 1 resting on the pivot point 5 via the plate 4 can then be turned over. The rotating end of the pivot point 5 is then moved along the ramp 3 to rest the cyclo-rail 1 on the railroad rails. At this point the pivot point 5 prevents the passage of the cyclo-draisin 1 forward. The pivot point 5 must be folded against the railway or removed from the latter if it is removable. If the ramp 3 is located on the rear half of the cyclo-draisin 1, the pivot point 5 must be placed behind the cyclo-draisine 1. If the pivot point 5 is fixed, it must be folded against the track, and if it is removable, it must be discarded. The cyclo-draisin 1 is then moved rearward along the railway rail until the rotatable end of the pivot point 5 engages along the ramp 3. The pivot point is then moved to the tray 4, so as to raise the cyclo-draisin 1 on at least two wheels of one of the axles. The cyclo-draisin 1 resting on the pivot point 5 via the plate 4 can then be turned over. It is then possible to roll the movable end in rotation along the ramp 3 until it rests on the rails of railroad. Cyclo-Draisin 1 is ready to start again.

When the turning device 2 comprises two ramps 3, the pivot point 5 fixed on the railway does not hinder the advance of the cyclo-draisin 1. Indeed, the rotatable end of the pivot point 5 along the ramp 3 placed in the front half of the cyclo-draisin 1, until reaching the plateau 4. At this stage, the cyclo-draisin 1 can be returned. The rotatable end of the pivot point 5 can then engage along the ramp 3 placed in the rear half of the cyclo-draisine 1. The latter is ready to start forward.

To return a scooter 1 equipped with a pivot point 5, it is necessary that the railway is provided with a turning device 2. Having two ramps 3 on the device 2 does not simplify the turning process which is The turning device 2 is placed along the longitudinal axis of the railway, so that in the direction of travel of the cyclo-draisin 1 is located first, the second end 3b of the ramp 3. The cyclo-draisin 1 is then moved forward along the rails, and the rotatable end of the pivot point 5 engages along the ramp 3 until reaching the plateau 4. The cyclo-draisine 1 is then raised on at least two wheels of an axle, so that it is possible to turn it over. The rotatable end of the pivot point 5 is then moved along the ramp 3, until the cyclo-rail 1 is rested on the railroad rails. The latter is ready to go back to the front.

The present invention is not limited to the features which have just been described. Those skilled in the art can, without departing from the scope of the invention, adapt the characteristics presented for a cyclo-draisine to a man-made or man-powered derrick. 5
