Description

 The Addition has for object a self-steerable vehicle powered by a system of pedals acting in particular on a chain.

 The purpose of the Addition is related in particular to the technical sectors of vehicles such as cycles, sports, games and entertainment.

 According to the Addition, it has been desired to appreciably improve the means for implementing the invention and the expected advantageous results.

 It will be recalled, according to the features of the patent, that the vehicle essentially comprises a frame receiving a wheel in particular treaded by a pedal mounted in a pedestal box integral with the frame shaped to receive a means serving as a seat; said frame being secured, particularly close to the bottom bracket, a device with rolling means, shaped to ensure the self-orientation of said vehicle by simple movements of suitable transverse inclination of the body of the user.

 According to the Addition, based on this design and the features of the patent, it has been conceived and developed an embodiment according to which the self-steering device of the vehicle is shaped and arranged with different means to be mounted. in a manner adjustable angularly and longitudinally with respect to the inclination of the frame, to vary the turning radius of said vehicle.

 These and other features will be apparent from the rest of the description.

To fix the object of the Addition, without however limiting it in the annexed drawing:
Figure 1 shows a partial front view of the self-orientation device according to the Addition mounted under the bottom bracket of the vehicle.

 Figure 2 is a cross-sectional view taken along the line 2-2 of Figure 1.

 Figures 3 and 4 are views similar to Figure 1 showing different inclinations of the self-orientation device, to define a more or less important turning radius.

 Figure 5 is a partial cross-sectional view of an alternative embodiment of the self-orientation device.

 In order to render more concrete the object of the Addition, it is now described in a nonlimiting manner with reference to the embodiments of the figures of the drawing.

 In Figures 1 to 4, the self-orientation device designated as a whole by D1 is equipped with a self-orienting rolling system of the type of those mounted on the skateboards.

For a better understanding of the remainder of the description, it will be recalled, by way of an indicative, non-limiting manner, that the self-orienting rolling system comprises a fixing support 15 with a profiled and inclined axial core 15 for the angular engagement of a hinge pin 16 forming a bearing flange 161 receiving or forming the axle 16 2 and authorizing the mounting of adjustable damping means A connected to the support 15. Rollers R or other rolling means are mounted to freely rotate at free ends of the axle 162.

According to the Addition, the device D1 is conform and arranged with different means, to be mounted in a manner adjustable angularly with respect to the inclination of the vehicle
For this purpose, it comprises a tube 17 fixed by any known and suitable means such as welding, to the box 18 of the frame 19. This tube 17 cooperates with a bearing plate 20 arranged directly or in a reported manner, to allow it different inclinations by support to said tube 17 with further locking means in the desired angular position. The support plate 20 allows the mounting of the self-orienting rolling system, in particular the support li.

 In a preferred manner, although not limiting, the free end of the tube 17, opposite its location of attachment relative to the frame 19, is machined to form two parallel plane faces 171 and 172 er3 each forming striations 3 17 or other asperities or shapes recessed and raised (Figure 2). The striated end of the tube 17 is freely engaged between two shells 201 and 202 formed perpendicularly and laterally to the base plate to form a yoke. The opposite faces of the shells 201 and 202 are also striated 3 in 203 in a concentric manner, being able to co-operate with the grooves 17 of the tube 17.

 A clamping member 21 freely passes through the shells 201 and 202 and the tube 17 which are respectively drilled transversely from one side to the other, the clamping member 21 is shaped to allow the axial approximation by elasticity, said shells relative to each other. at the ridged end 173 of the tube to ensure the angular locking in position by interlocking the ridges or other hollow and raised shapes of the shells 201-202 and the tube 17. For example, a clamping member of the tube may be used. type of those known as rapid blocking (Figures 1 and 2).

 The bearing flange 20 with the ridged shells 201 and 202 eS in a preferred manner, plastic material being obtained directly by molding.

 It is therefore conceivable that according to the Addition, after suitably mounting the self-steerable bearing system on the support plate 20, it suffices to engage the ridged end 173 of the tube 17 between the striated facing faces 203 the two shells 201 and 20 and ensure the assembly of the assembly by the clamping member 21. When the latter is not completely blocked, it is possible to rotate the entire device D1 relative to the tube , the different grooves 20 and 173, respectively relating to the shells 201-202 and to the tube 17, do not mesh with each other. However, when acting in a locking manner on the clamping member 21, The last effect has the effect of bringing the shells 201 and 20L axially closer together by elasticity, the striations of which come privately with the corresponding ridges 173 of the tube 17 thus ensuring the locking in the angular position of the device by preventing the circular pivoting in particular of the shells 201 and 202. compared t at the striated end of the tube 17.

 It is therefore possible to mount the entire device D1 ensuring the self-orientation of the vehicleS in different angular positions with respect to the inclination of said vehicle, thereby conferring, to a greater or lesser degree, steering radius.

 For example, when the hinge pin 16 of the self-standing system tends to a horizontal position (FIG. 3), that is to say that the device D1, in particular the rolling means R1, tend to approach the vertical passing through the center of gravity of the user notmalement seated on the vehicle, one obtains a large turning radius. Conversely, when the hinge axis 16 tends towards a vertical position (FIG. 4), that is to say that the device D1 tends to move away from the vertical pessant by the user's center of gravity. sitting on the vehicle, we get a small turning radius.

 In the embodiment of Figure 5, the device D1 is my tee as previously to the bottom bracket being likely to occupy different angular positions relative to the vehicle, only the self-directional bearing system is different.

 In fact, it can be seen that it essentially comprises a support yoke 22 forming a yoke and mounted to rotate freely with respect to the bearing flange 20 by means of any bearing member 23 capable of conferring on the assembly a complete rotation of 36osa. degrees. The rolling means is in the form of a single wheel 24 mounted between the vertical branches 221 and 222 of the clevis suppott 22.

 It is obvious that without departing from the scope of the invention, it is possible to provide other means and equivalent arrangements capable of ensuring the adjustable lateral angular positioning of the self-orientation device with respect to the inclination of the vehicle. For example, the tube 17 can cooperate with an open and independent clamping collar that forms striated or other asperities cooperating with complementary hollow and raised forms established in the shells 201 and 202 of the bearing plate 20 receiving the rolling system.

 The advantages are apparent from the description, in particular the possibility of varying the turning radius allowing better adaptation and use of the hard vehicle different terrain profiles.

 The invention is in no way limited to that of its modes of application nor to those of the embodiments of its various parts which have been especially indicated; on the contrary, it embraces all variants.
