Definitions

  • the present invention relates to a sporting device which is particularly applicable to the simulation of sliding sports such as cross-country skiing on hard floors such as in particular roads.
  • Such devices reproduce only very imperfectly the sensations of cross-country skiing, in particular in the simulation of the gliding and of the movement of the skier's legs causing the gliding.
  • cornering with such devices can only be done using the so-called "not-turning" technique which requires that the user already has a good experience of skiing which hinders the use of such devices by non-initiates thus limiting the prospects of dissemination of such devices to the general public.
  • they require great dexterity of the user when he wants to slow down.
  • the present invention aims at the design of a sporting device intended in particular for simulating sliding sports on hard surfaces such as roads, the use of which does not require any particular prior experience, which ensures good safety, even to an uninitiated user, and to whose use the inconvenience due to vibrations due to roughness possibly on the roadway are considerably reduced.
  • the present invention relates to a sporting device, characterized in that it comprises a wheel of which an external peripheral surface constitutes a first rolling member on a ground or on a hard surface and of which an internal peripheral surface constitutes raceway for a second rolling member of a support capable of supporting a foot of a user, and means for connecting the wheel to the body of the user allowing it to be held perpendicular to the ground without hampering its rotation.
  • the support advantageously comprises a main caster constituting, by tangential contact with said internal surface of the wheel, a rolling member of the support, said main caster being intended to support the radial force and the axial force exerted by the weight of the user. on the support; and two counter rollers in tangential contact with said outer surface of the wheel, said counter rollers constituting, in cooperation with said rolling member of the support, means for guiding and holding said support relative to the wheel, said counter rollers rollers being arranged on either side of said main caster in the longitudinal direction of the support and preferably equidistant from said main caster.
  • the rolling on the ground now takes place by means of a wheel which has a diameter substantially larger than that of the rollers of the known pads and which is interposed between the ground and a main caster serving as a rolling member for the support.
  • the diameter of the wheel is such that the rolling of the support on its internal path is carried out without fatigue and that the center of gravity of the support is maintained at a short distance from the ground which improves the stability of the device.
  • the point of tangency of the main caster on the internal surface of the wheel is aligned with the center of the wheel and the point of tangency of the wheel on the ground.
  • a shift in the center of gravity of the user relative to this alignment results, depending on the direction of the shift, by a weight transfer on the tiptoe and therefore on the front of the support or on the heel and therefore on the rear of the support thus causing the skate to tilt forwards or backwards respectively and a shift in the point of tangency of the main caster relative to the alignment of the center of the wheel and the point of tangency of the wheel on the ground.
  • the cycloidal movement thus created makes it possible to simulate in a very realistic way the gliding sensations that a user can have on skis.
  • the point of tangency between the main caster and the inner raceway of the wheel constituting the point of tilting of the shoe. Turning can now be carried out without having to take off a device from the ground thanks to the tilting of the skate.
  • the two counter-rollers which are each arranged at one end of the support, make it possible to guide and hold the shoe in relation to the wheel, thereby enabling the pendulum movement by tilting the shoe alternately forward and inward. rear be carried out safely.
  • the support advantageously comprises in a lower front part, a pad capable of bearing on the ground during an inclination of the support relative to the horizontal towards the front; and in a rear lower part, said support comprises in a rear lower part a stabilizing wheel capable of bearing on the ground during an inclination of the support relative to the horizontal towards the rear.
  • the buffer and this stabilizing wheel improve the simulation of a sliding sport such as cross-country skiing.
  • the buffer allows the device to be propelled during a front tilting or tilting towards the front of the support, and the stabilizing wheel ensures the balance of the device during a tilting or a rear tilting of the support.
  • the support advantageously comprises in an upper front part means for fixing a point of a shoe, said fixing means being articulated so as to allow the heel of the shoe to be detached from the support, said support preferably comprising in a rear upper part, a heel for the heel of the shoe.
  • binding means may for example consist of conventional means for attaching a cross-country ski boot and thus allow the user of the device to recover the sliding sensations of the cross-country ski by performing the same propulsion movements as 'he would perform on skis.
  • a heel for the heel of the shoe is preferably provided in the upper rear part of the support.
  • the support advantageously comprises two side walls framing the wheel and comprising means for fixing the axes of said rollers and counter-rollers, said walls being connected in their upper part by a plate intended to support the foot of the user.
  • the shape of the support chappe which is guided on the wheel by means of the main caster placed approximately in the center of the support and of the two counter-rollers positioned preferably at the ends thereof, allows the center of gravity of the support to be located as close to the ground as possible without hampering the operation of the device.

  • the wheel is thus linked in its part opposite the ground to the body of the user, it can thus be held approximately perpendicular to the ground so as to ensure good stability to the device.
  • said rigid member advantageously comprises a triangular stirrup of which two parallel walls connected by guide rollers surround the wheel, two casters preferably bearing on said internal peripheral surface and at least one roller bearing on said external peripheral surface , said stirrup being linked to the body of the user by said flexible attachment means and thus allowing a connection of the wheel to the body without hampering its rotation.
  • said rigid member advantageously comprises a fork whose branches extend on either side of the wheel and whose handle is linked to the body of the user by said attachment means, said branches being parallel and sufficiently spaced to allow guidance without hampering the rotation of the wheel.
  • braking means which are provided with a shoe articulated on said rigid member and can, in an activated position, rub on the wheel, said braking means preferably being provided with remote control means;
  • the wheel has a rim on the outer peripheral surface of which is bonded a first rubberized belt, or, according to another embodiment, a rim on which is attached a tire, preferably inflated with air;
