DESCRIPTION OF PREFERRED EMBODIMENTS
A snow board S has a blow-molded plastic body 10 of substantially conventional shape.
A top wall 12 of the body 10 is provided with first and second bindings 14 and 16 respectively. A detailed description of the bindings 14 and 16 and the relationship thereof with the body 10 will be given hereinbelow.
The tip 18 of the body 10 is slightly curved upwardly to imitate a snow ski and, more particularly a water ski or a surfing board. Similarly, a middle part 20 of the body 10 is curved.
Now referring to FIG. 3, a bottom wall 22 of the body 10 is provided with first, second, third, fourth, fifth and sixth slots which are defined therethrough and are numbered 24, 26, 28, 30, 32 and 34 respectively. Slots 28 and 30 are clearly seen in FIG. 3, as slots 24, 26, 32 and 34 are obscured by lower parts of the bindings 14 and 16 which are to be described later. The first binding 14 can be positioned either into the slots 24 and 26 as it is represented on the drawings, or into slots 28 and 30. In the first case, the left foot of the rider is secured into the first binding 14 and the right foot thereof into the second binding 16, whereas slots 28 and 30 are used for positioning the right foot of the rider into the first binding 14. The slots 24, 26, 28 and 30 are defined substantially at a 45.degree. angle with respect to the longitudinal axis of the body 10 of the snow board S, whereby the front foot of the rider is at the same angle relative to this longitudinal axis. The slots 32 and 34 are defined transversely with respect to the body 10 for positioning the rear foot of the rider substantially perpendicularly to the longitudinal axis of the snow board S.
Both the first and the second bindings 14 and 16 being constructed in a same fashion, only the first binding 14 will now be described. Corresponding parts of both bindings 14 and 16 will have the same number, the suffix "a" being added to the numbers associated with the second binding 16.
The binding 14 comprises first and second elongated plastic bands 36 and 38 respectively. Both bands 36 and 38 are mounted at lower ends thereof 40 and 42 respectively in the slots 24 and 26 of the body 10 in a way that will be described later. The bands 36 and 38 act as a strap for surrounding part of the front foot of the rider and, more particularly, overlying the front top and sides of the footwear. A first metal plate 44, fixedly mounted by way of nuts and bolts (not shown) to the first band 36, comprises a pivoting buckle 46 provided with a wire loop 48.
A second metal plate 50, fixedly mounted to the second band 38 in a similar way, includes a series of inclined metal transverse recesses 52 adapted for receiving the wire loop 48. By placing the wire loop 48 in the proper recess 52 and by pivoting the buckle 46 away therefrom, the bands 36 and 38 overlap enough for ensuring tightness of the foot therein.
A pair cf elongated straps 54 and 56 are respectively fixed at first ends 58 and 60 thereof respectively to lower parts 106 and 108 of respective bands 36 and 38 adjacent the top wall 12 of the body 10 by way of a nut and bolt arrangement which is typically illustrated in FIG. 8 as 104. Respective second ends 62 and 64 of the straps 54 and 56 are joined together bY nuts and bolts 110. The straps 54 and 56 are provided with a longitudinal series of holes defined therein for allowing proper adjustment thereof on a back portion of the footwear. Such holes are shown as 66 on the strap 56a in FIG. 1.
The bands 36 and 38 are provided with slight plastic elevations 68 and 70 which are integral thereto and on which are respectively mounted the plate 44 holding the buckle 46 and the plate 50 including the recesses 52. Similarly, the plates 36a and 38a are provided with respective elevations 68a and 70a. Such elevations are best seen in FIGS. 1, 2, 4, 5 and 8.
Holes 72 are defined through the elevation 70 and corresponding underlying section of the band 38 for allowing respective adjustment of the plate 50, a bolt and nut arrangement 74 being used therefor which is typically shown as 74 in FIG. 1 for the plate 50a of the band 38a.
The bands 36, 36a, 38 and 38a are all mounted to the body 10 of the snow board S in a same way. FIG. 4 illustrates how the band 38a is mounted to the body 10. The band 38a is upwardly slid in the groove 32 as shown by the vertical arrow 76 and then pivoted in the direction of the arrow 78. The bottom part 42a of the band 38a is enlarged for engagement thereof in the groove 32 as best seen in FIG. 5. This prevents any upward displacement of the band 38a relative to the body 10. The downward motion of each of the bands 36, 36a, 38 and 38a is prevented by slight tapered protrusions provided near the respective lower parts 106, 106a, 108 and 108a of these bands. Such tapered protrusions are shown as 80 and 80a respectively for the bands 38 and 38a as can be seen in FIGS. 4, 5 and 8. A downward movement of the bands 36, 36a, 38 and 38a is further prevented by the attachment thereto of the first ends 58, 58a, 60 and 60a of the straps 54, 54a, 56 and 56a, as best seen in FIG. 8 wherein the first end 60 of the strap 56 is mounted to lower part 108 of the band 38 and contacts the upper wall 12 of the body 10 for preventing a downward displacement of the band 38 with respect to the body 10.
Now referring to FIG. 3, the bottom wall 22 of the body 10 is provided with a series of reinforcement grooves and recesses which extend between the top and bottom walls 12 and 22. A first pair of grooves 82 and 84 is defined substantially longitudinally with respect to the body 10 intermediate the tip 18 thereof and the slots 24, 26, 28 and 30 used for the mounting of the first binding 14. The grooves 82 and 84 are slightly tapered near forward ends 86 and 88 thereof. Rearward ends 90 and 92 of respective grooves 82 and 84 are substantially defined parallel to the respective slots 26 and 30 in order not to weaken the body 10 of the snow board S.
A second pair of grooves 94 and 96 is longitudinally defined in the bottom wall 22 of the body 10 intermediate the first and second bindings 14 and 16. These grooves are slightly tapered at both ends thereof as shown in FIG. 7.
Areas of the blow-molded body 10 bearing the weight of each foot of the rider are reinforced by way of the slots 24, 26, 28, 30, 32 and 34.
Furthermore, a pair of circular recesses 98 and 100 is provided in the bottom wall 22 of the body 10 substantially intermediate the slots 32 and 34 for the second binding 16. The circular recesses 98 and 100 tapered from the bottom wall 22 of the body towards the top wall 12 thereof, are aimed at reinforcing a rear end part 102 of the body 10 of the snow board S on which the weight of the rearward foot of the rider substantially lies.
The snow board S is therefore characterized by being of blow-molded construction and by comprising a pair of substantially fixed bindings 14 and 16 with respect to the body 10 thereof. Grooves and recesses 82, 84, 94, 96, 98 and 100 are provided in the bottom wall 22 of the body 10 for the reinforcement thereof. The configuration of the slots 24, 26, 28 and 30 allows for the first binding 14 to be mounted to the body 10 either for a front left foot or for a front right foot. The slots 32 and 34 can also accommodate the second binding 16 for allowing a rear left foot or a rear right foot.
The bindings 14 and 16 are designed for accommodating substantially any kind of footwear and, more particularly, any winter footwear, which, thus, results in a low cost snow board S.
