Therefore, one understands that a binding of the type illus trated in the document cited hereinabove might not absorb BACKGROUND OF THE INVENTION Such forces. 0002) 1. Field of the Invention SUMMARY OF THE INVENTION 0003. The present invention relates to system for binding 0011. Therefore, an object of the invention is to propose a boot to a Sports apparatus including a device to quickly a binding System for a Snowshoe that perfectly holds the fasten the apparatus to the user's feet boot on the Snowshoe while being very simple to use and 0004. The invention can be used for various sports appa inexpensive to manufacture. ratuses Such as Snowshoes, roller skates, ice skates, short 0012 To this end, the invention proposes a system for skis, a crampon plate, etc. binding a boot on a Sports apparatus, in particular a Support 0005 The invention is more particularly described within Surface of a Snowshoe, of the type in which the binding the Scope of its application to Snowshoes in which both the System includes a front binding and a rear binding, wherein forefoot and the heel of the user remain in constant contact the front binding is formed of a hook-like member that is with the corresponding Support Surfaces of the Snowshoe, affixed to the apparatus and demarcates a notch open lon contrary to binding Systems in which the heel remains free. gitudinally rearward and transversely on both sides to 0006 2. Description of Background and Relevant Infor receive a front transverse rod of the boot, and wherein the mation rear binding longitudinally immobilizes the boot in a posi tion Such that the transverse rod of the boot is maintained 0007 Various devices exist, which make it possible to within the notch. fasten the Snowshoes to the feet of the user. One of the most widely known devices uses two Sets of Straps that cooperate 0013) A very simple binding system is thus obtained, in with the forefoot and with the instep, respectively, So as to which the forefoot is perfectly blocked vertically and trans Steadily maintain the user's boot pressed against correspond versely without using conventional Strap Systems. ing Support Surfaces of the Snowshoe. Generally speaking, 0014. The invention also proposes a snowshoe provided front and rear abutment Systems are provided, which, com with Such a binding System. bined with these Sets of Straps, make it possible to ensure the longitudinal and transverse blocking of the boot on the BRIEF DESCRIPTION OF DRAWINGS Snowshoe. 0015. Other characteristics and advantages of the inven 0008 Such devices perfectly fulfill their role, but they tion will become apparent from the detailed description that have the disadvantage of requiring two sets of Straps to be follows, with reference to the annexed drawings, in which: positioned on each foot, which can be time consuming and difficult, especially when the user wishes to put on or remove 0016 FIG. 1 is a perspective view of a snowshoe pro his/her Snowshoes in cold weather, with numbed fingers or Vided with a binding System according to the prior art; with gloves on. 0017 FIG. 2 is a view similar to the same Snowshoe 0009 U.S. Pat. No. 5,881,477 describes a snowshoe to equipped with a binding System according to the invention; which a binding System, derived from the Systems used in 0018 FIG. 3 is a partial cross-sectional view, along a cross-country skiing, is adapted. In this patent, the boot worn longitudinal vertical plane, showing the front binding of the by the user includes, at its front end, a transverse cylindrical boot on the Snowshoe; rod that is blocked in a cylindrical housing with the same diameter to form a journal. The housing is demarcated by a 0019 FIG. 4 is a schematic top view showing the means System with jaws, and it includes an opening and closure for transverse blocking of the front of the boot, the sole of mechanism to enable the engagement and disengagement of the boot being shown in cross-section. the front transverse rod of the boot. When the housing is closed, the rod only has one degree of freedom left, namely, DETAILED DESCRIPTION OF THE the rotation about its transverse axis. INVENTION 0.010 However, this type of binding, derived from cross 0020 FIG. 1 shows a snowshoe 10 equipped with a country ski bindings, has the disadvantage of being rela binding System designed according to the prior art. The tively complex and expensive for a product Such as a Snowshoe itself is of the type of that described in the Snowshoe. Furthermore, since the binding of the boot is document EP-A-882478 and U.S. Pat. No. 6,112,436, for ensured only at the front, the retention between the boot and example. This Snowshoe essentially includes a frame 12 US 2002/0104234 A1 Aug. 8, 2002 made of an injected plastic material and which forms a 0026. The base 34 is extended at its front end by a front Screen capable of withstanding the users weight without the wall 40 that rises above the front end 42 of the plate 14. Snowshoe Sinking too deeply into the Snow. The Snowshoe From the upper end of the front wall 40, the hook 32 further includes a plate 14 that is journalled on the frame 12 includes two teeth 44 that are transversely offset in relation about a substantially transverse axis A1. Preferably, the to one another and which extend longitudinally rearward, journal of the plate 14 on the frame 12 is made according to above the front end 42 of the plate 14 and parallel thereto. that which is described in the EP-A-88.2478 and U.S. Pat. 0027. In a cross-sectional view along a longitudinal trans No. 6,112,436. The plate 14 is made of a rigid plastic verse plane, the hook 32 thus demarcates, together with the material, for example, and it includes an attachment device upper surface of the front end of the plate 14, a notch 46 that to enable the fastening of the user's boot thereto. is open longitudinally rearward and is closed on its other 0021. In the example shown in FIG. 1, the binding three sides. Thus, the notch is substantially U-shaped toward System according to the prior art includes a rear binding 16 the rear. AS can be seen in FIG. 2, the notch 46 is however and a front binding 18 which are both strap bindings and are open transversely on both sides along its entire length. both anchored on the plate 14 So that the boot is entirely affixed to the journalled plate 14. 0028. According to the invention, this front binding 30 0022. The rear binding 16 includes a rear abutment 20 with a hook 32 is provided to cooperate with a boot 48 whose shape is Substantially complementary to that of the whose front end includes a transverse connection rod or heel of a boot, in order to block the boot both longitudinally member 50.
