Definitions

• the present invention aims to facilitate the operations of putting on and taking off a shoe on a snowboard, while ensuring effective support of the shoe.
• bindings for rigid boots such as ski boots
• bindings for flexible boots of the boot type There are, on the one hand, bindings for flexible boots of the boot type.
• the former generally use footpegs blocking the boot on the snowboard thanks to an easy-to-operate locking lever.
• the operations of putting on and taking off are easy.
• the boot is strapped in a binding composed of a base fixed on the snowboard and a rear support (called “spoiler") coming to hold the bottom of the calf, fixed perpendicular to the rear of the base. Straps attached to the base keep the boot on the snowboard.
• the present invention aims to improve the current technique to make putting on and taking off quicker and easier, while ensuring good rear support.
• Document FR-A-2,631,843 also discloses a ski boot comprising a rear support means and a front support means connected by a bent lever.
• This system is not satisfactory as a ski boot. In fact, no means of blocking the assembly is provided. If the skier exerts a force on the rear support means, the assembly pivots towards the rear, the bent lever driving the front support means upwards, which eliminates the maintenance of the kick. 3 Furthermore, the direct application of this system to a flexible boot is not possible for the same reasons.
• the present invention aims to provide, in addition to the putting on and taking off facilities, a real rigid rear support necessary for the practice of snowboarding.
• the present invention has, firstly, the object of providing a binding capable of being used in particular with booties, and which can be fitted from the rear while providing the practitioner with excellent rear support.
• This objective is achieved in accordance with the invention with a fixing device for snowboarding intended to hold the foot of a snowboarding practitioner thereon, characterized in that it comprises: a rear support means intended to bear against the rear of the ankle, at the Achilles tendon and at the bottom of the calf,
• the locking device keeps the rear support means substantially vertical and the pressure of the kick holding means, so as to allow the use of the snowboard.
• the force towards the rear of the bottom of the calf exerted on the rear support means is fully transmitted to the base and therefore to the snowboard, by means of the locking device.
• the unlocking of the locking device allows pivoting towards the rear of the rear support means and the simultaneous loosening of the boot for heaving.
• the fastening or fastening device for snowboarding and quick heaving has the advantage of a more comfortable position for the practitioner during shoeing-heaving operations, the latter no longer having to sit down; but standing on his snowboard, he only has to bend down to manually activate his bindings.
• the base is not necessarily mounted directly on the snowboard, but can be mounted on the latter via an adjustment device, such as that which is the subject of PCT application FR 91.00919 published under the number WO 92/09339.
• At least one of said first and second axes is substantially perpendicular to a longitudinal axis of the base;
• Said rear support means comprises a shell adapted to wrap a part of the back of the ankle of said practitioner, in particular at the level of the Achilles heel and the bottom of the calf;
• the kick holding means comprises a shell adapted to wrap part of the kick and the ankle;
• the means for maintaining the kick comprises at least one strap
• the kick holding means has, at the front, a mounting portion on the base which is adapted with the latter, to allow sliding of the mounting portion so that in the open position of the means back support, there is loosening of the front part of the foot and in the closed position, there is a tightening of the front part of the foot;
• the front of the kick holding means has two sliding lugs, while grooves are arranged on the base; - The front of the kick holding means has two sliding grooves, while pins are arranged on the base.

• a rear support means 2 is linked to the base 1 by two pivots, only one of which, marked 60 is visible in FIG. 1, along an axis 6 around which it can pivot by sweeping a sector of 180 ° above the base 1.
• a means for maintaining the kick 3, in this case a strap, is fixed by means of rear support 2 by two other pivots of which only one, marked 70 is visible in FIG. 1, according to a axis 7 eccentric with respect to axis 6.
• the rear support means 2 comprises a shell 2 ′ adapted to wrap part of the rear of the practitioner's ankle, in particular at the level of the Achilles heel and the bottom of the calf.

• the means for maintaining the kick 3 has reached its low point; he then presses on the kick of the boot 10 while holding it firmly on the base 1 and against the rear support means 2 where its rear face can bear.
• the rear support means 2 is in a horizontal position and the released boot 10 can escape from the attachment from the rear along the arrow marked II.
• the complementary strap 3 ′ as well as the means for maintaining the kick 3 are provided with means for pre-adjusting their length, making it possible to adapt them exactly to the size of the boot 10 which may differ according to the models. and sizes. This initial adjustment having been carried out, it can be seen in FIGS. 1, 3 and 4 that only the movement of the rear support means 2 maintains the boot 10 without it being necessary, as for known bindings, to carry out the tightening individual straps for each fitting operation.
• FIG. 5 it can be seen that it is possible to equip the means for maintaining the kick 3 with a complementary bi-position tightening lever 8 allowing, if necessary, to easily modify the pressure on the boot 10 by tilting and lifting the lever 8.

• FIG 8 is a partial cutaway view of the locking device identified 4 and 5 or 4 'and 5' in Figures 1 and 3 to 7.
• This device consists of a piston 4 extended by a rod 40 sliding in a housing or cage integral with the rear support means 2.

• FIG. 9 shows, by way of example, a variant of the locking device which uses, a pawl 14 oscillating around the pivot 70 along the axis 7 and provided with an elastic device 15, here represented by a return spring, and with a ring 16. The pawl 14 is pushed by the ramp of the stop 13 before engaging behind that here when the rear support means 2 is in a substantially vertical position.
