Definitions

  • the invention relates to the field of means for retaining a shoe on a gliding board intended for the practice of snowboarding.
  • the invention relates more particularly to means for retaining a shoe which allows movements of flexion or inclination of the leg relative to the foot of a user.
  • the user is always required to make movements with the body and the limbs to manage his balance at the same time as he is driving the board. It turns out to be very difficult to perfectly coordinate the management of balance and the handling of the board in curved trajectories, in turns or on a bump.
  • This change in inclination generally has the effect of suddenly modifying the contact surface of the board on the ground.
  • the driving is disturbed and the trajectory control is random, because the reaction forces of the ground on the board vary in considerable proportions.
  • the prior art has proposed devices which give a certain flexibility of positioning between each foot and the board.
  • document FR 2 650 752 This is for example the case of document FR 2 650 752, the aim of which is to allow the user to place himself in the most comfortable and balanced position during the changes, thanks to flexible joints arranged between the feet. and the board.
  • the device according to document FR 2 650 752 does not, however, allow the user to manage the support variations. Indeed, the flexibility of the joints does not favor precise guidance and does not allow the user to correctly identify the sensory information he receives. Therefore, this system is not really satisfactory and control of curved trajectories is difficult, if not impossible.
  • Document DE 89 02 125 proposes a device for retaining a shoe on a board comprising a shell articulated on a base along a transverse axis. The articulation allows a range of the device for transport.
  • a removable elastic means is able to hold the shell relative to the base in a position of use. The elastic means acts to limit a flexion movement from the lower leg to the foot. It follows that the user can easily take support with the forefoot.
  • the object of the invention is to remedy the drawbacks listed above. To do this, it proposes a device for retaining a boot on a gliding board, the device notably comprising a back support element for ensuring the rear support of the lower leg and a base intended to receive the sole of the shoe, the back support element being articulated on the base along a substantially transverse axis YY 'of the device.
  • the invention is characterized in that at least one elastic means biases the dorsal support element relative to the base according to an articulation movement along the axis YY 'in a direction of flexion of the lower leg towards the foot or postero-anterior.
  • This structure in fact allows the lower limbs to be able to tilt relative to the board so that the back support element remains in permanent contact with the lower leg, whatever the trajectory of the board. It follows that the user can perceive sensory information continuously.
  • the invention is characterized in that the back support element is in one piece. This structure gives the device a lateral stiffness with respect to the foot which is suitable for cornering.
  • the invention is characterized in that the back support element comprises a shell and a hoop articulated relative to each other along an axis XX 'situated in a substantially longitudinal plane of the device.
  • This structure gives the device a degree of lateral freedom of the lower leg relative to the foot which is suitable for the execution of figures of style.
  • the invention is also characterized in that a stop means limits the articulation movement of the back support element relative to the base according to the axis YY 'in a direction of extension of the lower leg relative to the foot or anteroposterior direction.
  • An alternative embodiment of the device according to the invention is characterized in that the elastic means is a compression spring, one end of which urges the back support element and the other end of which urges the base, in a direction of remoteness.
  • the advantage is that the spring eliminates the snow wedges.
  • Another alternative embodiment of the invention is characterized in that the elastic means is a torsion spring, one end of which is linked to the back support element and the other end of which is linked to the base.
  • This alternative embodiment has the advantage of a small footprint.
  • FIGS 1 and 1a show a gliding board 1 on top of which are fixed two retaining devices 2 of the shoes 3 of a user.
  • Each device 2 comprises a base 4 for maintaining the foot and a back support element 5 for taking support, in particular when cornering where the user leans on the rear edge and has his back facing the slope.
  • the devices 2 are oriented respectively in a substantially transverse direction of the board 1, so that the ends of the feet are close to a longitudinal front side 6, and the heels are close to a longitudinal dorsal side 7 of the board 1 .
  • Each device 2 comprises means for retaining the boot 3 on the device 2, represented in the form of straps 8, 9, 10, two straps 8, 9 holding the boot 3 on the base 4 at foot level, and a strap 10 now the shoe 3 on the back support element 5 at the lower leg.
  • the back support element 5 is articulated relative to the base 4 by an articulation means, shown here in the form of rivets 11, so that the back support element 5 can pivot relative to the base 4 around a substantially transverse axis YY 'of the device 2.
  • the axis YY' is transverse with respect to a longitudinal direction of the device 2 extending substantially from the fingers towards the heel of the foot.
  • an elastic means biases the back support element 5 relative to the base 4 according to a rotational movement relative to the axis YY ′ in a direction of bending from the bottom of leg towards the foot.
  • This elastic means can be a compression spring 12 visible in FIGS. 1, 1a, 2, 3, 4.
  • the stress exerted by the elastic means can be permanent or temporary.
  • the spring 12 is guided by a bar 13 of cylindrical section.
  • the spring 12 is supported by one of its ends on a cup 14 secured to the bar 13 by any suitable means such as a weld 15.
  • the spring 12 is supported by the other end on a plug 16 itself fixed on a sheath 17, for example by means of a thread 18.
  • the plug 16 is pierced in its center by a reamed hole 19 which serves to guide the rod 13 in a direction of compression or extension of the spring 12.
  • the sheath 17 is extended at its end opposite to the plug 16 by a flat 20 pierced with a hole 21 with an axis 22.
  • the bar 13 is extended at its end exiting by the reamed hole 19 by a flat 23 pierced with a hole 24 d axis 25.
  • the bar 13 is therefore able to penetrate into the sheath 17 against the action of the spring 12 while being guided in the sheath 17 by the reamed hole 19 of the plug 16.
  • the sleeve 17 is articulated by the axis 22 common to a pin 26, to the hole 21 of the plate 20, and to two orifices of a base 27, on the element back support 5.
  • the bar 13 is articulated by the axis 25 common to a pin 28, to the hole 24 of the plate 23, and to two orifices of a base 29, on the base 4.
  • a means of stopping the movement of the back support element 5 relative to the base 4 in a direction of extension of the foot is achieved for example by the association of the bottom 35 of the scabbard and tip 36 of the bar 13.
  • the spring 12 is in a state of maximum compression.
  • the retaining device 2 allows a user to flex the legs quickly and easily while stressing the dorsal longitudinal side 7 of the board 1 towards the ground, thanks to the action of the spring 12. As a result, contact is made between the dorsal side 7 and the ground in turns or on bumps where the user has his back facing the slope of the terrain. The movements of the body and legs made to maintain balance therefore do not disturb the handling of board 1.
  • the plug 16 could be made of bronze, the bar 13 made of steel, the spring 12 made of alloy steel.
  • the back support element 5 comprises a shell 37 and a hoop 38 forming a single block, obtained for example from injected plastic.
  • the back support element 5 comprises a shell 39 articulated on a hoop 40 along an axis XX ′ substantially longitudinal of the shoe; the articulation can be done using a rivet or any other means and facilitates lateral inclinations of the lower leg, along the axis XX '.
  • the spirit of the invention is unchanged. Indeed, the spring 12 always biases the lower leg in flexion relative to the foot in the direction of the arrow F, acting between the arch 38 or 40 and the base 4 in a respective direction of separation.
  • FIGS. 5 and 6 Another embodiment of the invention is proposed using FIGS. 5 and 6. For reasons of convenience, the same parts are designated by the same references.
  • a back support element 5 comprising a shell 37 and a hoop 38 articulated on a base 4 along a substantially transverse axis Y-Y '.
  • a torsion spring 41 acts between the base 4 and the arch 38 to urge the arch 38 and maintain contact between the shoe 3 and the shell 37.
  • the ends 42 and 43 of the spring 41 are secured respectively to the base 4 and to the arch 38 passing through holes in the base 4 and the arch 38.
  • the spring 41 remains in place thanks to the permanent stress on an elastic washer 44 which is interposed between the base 4 and a shoulder 45 of a rivet 46 of axis Y-Y '.
  • the rivet 46 serves to hold the base 4 and the arch 38 relative to each other.
  • the rivet 46, the base 4 and the arch 38 can be made of metal or of synthetic material shaped by any known means such as injection or machining.
