  • Patented July 18, 1972 INVENTOR. Gea/'jes RJ'. .SALM/V broad States Patent Salomon [451 July 18, i972 [541 Low FRICTIoN BEARING AGEMENT Ton SKI BooT IN ooNTACT WITH A SKI [72] Inventor: Georges P. J. Salomon, 34 Ave. de
  • ABSTRACT A low friction bearing arrangement for a ski boot contacting a ski comprising at least one slot having a smooth bottom surface extending substantially across the ski boot and at least one corresponding frictionplate secured to the ski.
  • the assembly is relatively expensive, fragile and may be hindered in its operation by the presence of small stones.
  • the ski boot is raised with respect to the ski by the thickness of the above-mentioned elements, and this is detrimental to the practice of the ski sport in accordance with modern techniques.
  • the sole of the ski boot has a rugged surface and patterns adapted to prevent the sliding ofthe boot on snow or ice when walking without skis.
  • the rugged surface of the sole may catch small stones thus increasing the friction of the sole of the ski boot on the ski.
  • the main feature of the present invention is to overcome the above-mentioned drawbacks in a simple and effective manner.
  • the soles of the ski boots have, at the location where they contact the skis, one or more substantially transversal slots which are relatively narrow, advantageously smooth, and devoid of patterns to prevent the catching and holding of small stones therein capable of hindering the sliding of the ski boots on the skis.
  • the arrangement in accordance with the invention includes the attachment, to the skis, of friction plates corresponding to the slots in the soles of the ski boots. These plates permit the contact of smooth rubber or plastic elements with an equally smooth surface of metal or plastic.
  • a plate having a high coefficient of resistance to wear or to oxidation may be inserted or molded in each slot in the sole.
  • Stainless steel may, for example, be used for such plate.
  • the slots are preferably not located in the normal bearing area of the sole on the ground.
  • FIG. 1 is a perspective bottom view of a ski boot in accordance with the invention, only the sole of the boot being shown;
  • FIG. 2 is a perspective top view of a ski including part of the arrangement in accordance with the invention
  • FIG. 3 is a side view of the whole arrangement, in a simple embodiment ofthe invention.
  • FIG. 4 illustrates a detail of the arrangement shown in FIG. 3
  • FIG. 5 illustrates a second embodiment of the arrangement in accordance with the invention permitting a better resistance to wear.
  • the bottom of a sole l is provided with two slots 2 and 5 having smooth bottom surfaces, the depth of each slot being identified by reference numeral 9 and the width thereof by reference numeral 4.
  • the slot 2 is disposed at a distance 3 Inn from the front end of the sole corresponding to one third of the length of the sole, and the slot 5 is located in the heel of bottom of slot 2 may be flat or curved.
  • the ski 6 includes a friction plate 7 made of metal or plastic and secured to the ski by means of two countersunk screws l2.
  • the central axis of plate 7 is located at the same distance 3 mentioned in the description of FIG. l from the bearing surface of the front ski attachment I4.
  • the width 8 of the plate 7 is less than the width 4 of the slot 2.
  • the height ll of the plate 7 is greater than the depth 9 of the slot 2.
  • the friction plate 7 preferably has a shape corresponding to the shape of the slot 2 in the sole of a ski boot.
  • FIG. 3 illustrates the vassembly on a ski 6 of a sole l comprising two transversal slots 2 and 5 bearing on the corresponding friction plates 7 and 17.
  • the contact area of the sole l with the ski 6 is limited to the upper surface of the plate 7 creating the gap l0 between the normal surface of the sole and the ski.
  • This gap l0 may, however, be of relatively low value.
  • the small stones will practically have no tendency to remain on the smooth surface of slot 2, in contact with friction plate 7, the gap l0 permitting, on the other hand, their release from the space between the sole of the ski boot and the ski.
  • a boot plate 13 is inserted -or molded at the bottom of slot 2 to protect such slot from damages which may be caused by stones 15 entering the slot during walking without skis.
  • a low friction bearing arrangement for a ski boot in contact with a ski comprising:
  • a slot located substantially transversely across the lower face of the sole of the ski boot, said slot having a smooth bottom surface and two lateral edges, and
  • an anti-friction plate secured to the ski said plate having an upper face and being engaged with said slot, wherein said bottom surface of said slot bears on said upper face of said anti-friction plate whereby the whole lower face of the sole is spaced from the ski and is freed from contact with the ski.
  • a low friction bearing arrangement as defined in claim l including a bearing plate in the bottom of said slot with said bearing plate forming the surface against which said anti-friction plate bears.
