Definitions
- the invention relates to a ski boot, the sole has at least two smooth bearing surfaces intended to rest and slide on surfaces smooth of a safety fastener and extending transversely to the sole.
- Patent CH 674 623 there is also known a device central binding of a ski boot comprising two rollers mounted on horizontal axes in the front plate of the central binding, the shoe being provided with a transverse groove whose bottom constitutes a bearing and rolling surface for rollers.
- the shoe pivots securely with the plate, then the shoe, released from the means of front restraint, escapes from the rear restraint means by tilting.
- the only support surfaces are role of ensuring that the height between surfaces rest and the jaws of the restraining means constant and independent of the wear of the sole.
- the object of the invention is to produce a shoe having the same advantages with regard to the lateral or rotating movement, but offering in addition to good comfort, a more flexible walking sole and having better grip without losing its functionality as an interface between the leg and skiing, this shoe must also be able to be made in a more rational way.
- the ski boot according to the invention has the characteristics defined by claim 1.
- Soft boot-like rod can be finished regardless of the rigid midsole and the tread. It is then attached to the midsole, then the tread is overmolded or glued to the midsole, leaving the support surfaces free.
- the walking sole surrounds the bottom of the rod so as to ensure resistance and the waterproofness of the shoe over a certain height.
- the bearing surfaces are advantageously set back from the bearing surface of the sole on the ground, such so that they come less easily into contact with the ground and, if so, with less pressure, so as not to be damaged, in particularly scratched, which would reduce their ability to sliding.
- Figure 1 is a side view of the ski boot in which the rigid midsole has been shown in strong transparent lines.
- Figure 2 is a bottom view.
- the shoe shown comprises a rod 1 in the form flexible boot having, in known manner, zones 2 of woven material and zones, such as the zone 3, in flexible plastic.
- This boot is fixed, by example by gluing, on a midsole rigid 4 raised at the rear and on the sides, on the greater part of the sole length, so as to form a kind of cradle 5 in which is engaged rod 1.
- the midsole 4 is provided on its face lower, two transverse ribs 6 and 7 located respectively under the sole of the foot, in the metatarsophalangeal area, and under the heel. These ribs 6 and 7 are relatively wide and have a trapezoidal profile with small bases define two flat bearing surfaces 6a and 7a. views in plan, their surface is flat and smooth and they extend at least approximately in arcs of a circle around a point corresponding to the axis of rotation of the shoe on the binding during a stress in torsion. As can be seen in Figure 2, the ribs 6 and 7 do not extend over the entire width of the midsole. In its middle region, the midsole 4 also has two bases 8 and 9, also of trapezoidal profile and forming two additional bearing surfaces.
- a metal bar 10 Between these bases 8 and 9 is fixed, transversely to the sole, a metal bar 10.
- the rigid midsole is covered, by molding, with a tread 11 which also covers the bottom of part of the perimeter of rod 1, but leaving the surfaces free support 6a and 7a of the ribs 6 and 7 as shown in Figure 2, as well as the bases of bases 8 and 9 and the bar 10.
- the bearing surfaces 6a and 7a are flush with the surface of the walking sole 11. These bearing surfaces could however be significantly behind the The sole of the walking sole 11. It is the same. bearing surfaces of bases 8 and 9.
- the sole of step 11 is for example made of thermoplastic rubber known by the commercial abbreviation of TPR.
- the tread 11 has a clearance 12, extending the surface support 6a of the rib in the form of a groove, the depth is significantly less than the height of the rib 6. Similarly, at each end of the rib 7, the tread 11 has a clearance 13. On either side of the bearing surface bases 8 and 9, the tread 11 has a oblique surface 15 in the manner of a chamfer 16.
- Figure 1 shows the shoe attached to a safety binding 17 itself attached to a ski 18.
- This attachment includes two smooth bearing surfaces 19 and 20 on which the ribs 6 and 7.
- the bar 10 of the shoe comes engage and get caught between a pair of supports 21 and a cam 22 articulated around a horizontal axis 23, these supports 22 and the support of the cam 22 can be separated from each other against the action of springs.
- the attachment is additionally fitted at the rear with a lever 24 allowing the bar 10 to be released and, by therefore, to remove the binding.
- the center of arcs of circles defined above corresponds to the center bar 10, that is to say in the center of the organ of fixing by which the shoe turns on the fixing during torsional stress.
- the bearing surfaces 6a and 7a facilitate the release by sliding on the binding.
- the bearing surfaces 6a and 7a act as a fulcrum accompanied by a leverage favoring the triggering of the fixation.
- the bearing surfaces are advantageously set back from the bearing surface of the sole on the ground, such so that they come less easily into contact with the ground, and, if so, with less pressure, so as not to be damaged, in particularly scratched, which would reduce their ability to sliding.
- the rigid midsole could be suitable for any other type of ski binding.
- the rigid midsole could present a front sidewalk and a rear sidewalk protruding outsole 11 for the use of the boot with a conventional ski binding comprising a front stop and a heel piece.
- the bases 8 and 9 and the bar 10 would be fine heard deleted.
- Ribs 6 and 7 could be straight instead of being in an arc.
- the sole intermediary could be provided with any means or fixing member, for example means such as described in patent application FR 2 769 799.
- the bearing surfaces 6a and 7a could also be formed by the surface of a metal plate intended to cooperate with a safety fastener.
- the ribs 6 and 7 defining the bearing surfaces may have either come in one piece, molding, with rigid midsole, be reported. In the second case, they can be in any matter, in especially in metal.
- the bearing surfaces could be discontinuous, for example formed by studs.
- the midsole could extend only from the heel to the area metatarsophalangeal.
