Definitions

  • ABSTRACT A pressure distribution element for use with a ski boot, comprising first and second webs arranged to define grooves for receiving opposite edges of the leg openings of the boot.
  • the pressure distribution element may be made of molded plastics material, and may be used with boots which are closed by strap and lever fastenings.
  • the present invention relates to a pressure distribution element for boots such as ski boots, and to boots provided with such a pressure distribution element.
  • a pressure distribution element for use in closing the leg opening of a boot, said element comprising a first web having a first surface which is shaped to conform to a portion of a human leg which in use of such boot will receive pressure from said surface and a second web extending from the opposite surface of said first web, said second web being arranged to pass between the opposite edge regions of the leg opening of such boot when closed and serving to locate such opposite edge regions with respect to each other.
  • the invention further provides a boot in combination with such a pressure distribution element.
  • the first web absorbs the pressures derived from the edges of the boot leg portions, and because of its stiffness distributes them approximately equally over an area of the leg corresponding to the area of the surface of the first web disposed towards the leg of the wearer.
  • Opposite edge regions of the leg of the boot which face each other and, in the closed condition of the boot are in spaced relationship adapted to receive the first web of the pressure distribution element may be provided with overlapping boot leg portions or with boot leg portions which are provided with straps.
  • the pressure distribution element is preferably removably attached to the boot at one of the boot leg portions or at the exterior surface of the flap of the boot, by a detachable fixing device such as one or more press studs or a burr type fastener.
  • a detachable fixing device such as one or more press studs or a burr type fastener.
  • the outer surface of the second web is preferably provided with lateral edges externally overlapping the boot leg edges.
  • the fit of the leg of the boot in the tibial region of the leg of the wearer can be made so flush, by means of a pressure distribution element of the invention, that a substantially equal pressure exists all over the area over which pressure is exerted on the shinbone.
  • one or more pressure distribution elements can be provided to extend over a section of, or over the entire length of, the leg opening of the boot.
  • the cushioning of the flap of the boot can be of thin construction. The only remaining function of the cushioning is to take up slight deformations arising from tensioning of the tendon and the like, during movement of the foot of the wearer.
  • the pressure distribution element should be of substantially rigid construction, but the edge regions of the first web may be somewhat deformable for complete adaptation to the area of the leg of the boot acted upon via the flap.
  • the pressure distributing properties of the pressure distribution element should not, however, be significantly influenced by any deformable parts of the pressure distribution element.
  • FIG. 1 shows a view in perspective of one embodiment of the pressure distribution element of the invention
  • FIG. 2 shows a view, in perspective, of a ski boot equipped with the pressure distribution element of FIG. I in the tibial region of the leg opening of the boot;
  • FIG. 3 shows part of a section line Ill-III of FIG. 2.
  • FIG. 1 shows a pressure distribution element having a first web 2 and a second web 1 molded onto one of the faces of the first web 2, one of the fastening elements 4 of a burr type fastener 4, 5 being fixed to the opposite surface 3 of the first web 2 facing the interior of the boot.
  • the fastening element 4 extends in the form of a strip over the central area of the surface 3, in the longitudinal direction of the pressure distribution element. Laterally projecting edges 6 are formed on the second web 1; the edges 6, together with portions 7 of the first web 2 facing away from the leg, forming grooves 8 in the second web 1.
  • the pressure distribution element may be made of differing configurations dependent on whereabouts it is fitted into the leg opening the of the boot. However, the surface facing the leg should substantially conform to the shape of the adjacent leg region.
  • pressure distribution elements may be inserted into various regions of the leg opening of the boot. Apart from the different shapes determined by the position of fitting in the boot, a range of pressure distribution elements of diverse sizes for adaption to various leg dimensions in boots of one and the same size are available for any region of the leg opening of the boot. These pressure distribution elements differ in particular as to the width of the second web 1, so that for different leg dimensions the most favorable closing tension about theleg may always be achieved by selecting the correct pressure distribution element.
  • the pressure distribution element is detachably fixed to the boot, so as to make possible such adaptation to any particular leg dimension by interchanging the pressure distribution elements.
  • FIG. 2 illustrates a pressure distribution element fitted in the tibial region of the closure area of a ski boot, the boot having leg portions 9 and 10 which have edge regions 11 and 12 at the leg opening which edge regions are spaced from and located opposite each other in the closed condition of the boot and underlapped by a flap 13.
  • the ski boot can be equipped with one or more devices for removable attachment of one or more pressure distribution elements.
  • the flap 13 is on its outward side provided with one element of a burr fastener 4, 5, the cooperating element 4 of which is mounted on the surface 3 of the pressure distribution element 1, 2, which surface 3 faces the interior of the boot in the tibial region of the closure area, as can be seen from the partial section shown in FIG. 3.
  • the boot is provided with two straps l4 and 15 in the tibial region.
  • One end of each strap is attached to the leg portion 9 where these ends converge, while the other two ends engage lever type clasps l6 and 17.
  • a firm fit of the ski boot in the tibial region of the leg is essential for good guidance of the skis.
  • the straps 14 and 15 are, therefore, very strongly tightened so that striplike zones of elevated surface pressure are formed, which are particularly troublesome at those places where the straps are passed over the edge regions of the boot leg portions, or, if an overlapping form of boot leg is used, over the overlapping area of the boot leg portion.
  • the pressure of the straps is spread over a larger surface area of the leg when a pressure distribution element of the invention is used, its surface 3 being conformed to the shape of the adjacent area of the leg of the wearer so that the pressure is diminished and firm contact of the leg with the boot is achieved in the closure area of the boot.
  • the most favorable closure conditions may be expertly predetermined having regard to the width of the second web and the particular leg dimension, such favorable conditions being obtained when the edge regions 11 and 12 abut the grooves 8 of the second web 1. A safe measure of the tension to be used is thus available to the skier, so that both too loose and too tight encasing of the leg of the skier is prevented.
  • the straps are pulled up a little more tightly than would be necessary for abutment of the edge regions 11 and 12 and the second web 1.
  • this excess tension is not transferred to the leg of the skier. It does, however, ensure a constantly firm fit, even when stretching and displacement of those portions of the boot which encircle the leg occur during use.
  • a pressure distribution element for use in the closing of the leg opening of a boot provided with opposite edge regions and provided with a tongue portion, the pressure distribution element com rising, in combination:
  • a first web avmg a first surface which 1s shaped to conform to a portion of a human leg and a second surface on the side ofthe first web opposite to the first surface;
  • first web having a first surface which is shaped to conform to a portion of a human leg and a second surface on the side of the first web opposite to the first surface;
  • a second web extending from the second surface of the first web and arranged to pass between the opposite edge regions of the leg opening of the boot when the boot is closed;
  • the tongue having an outer surface, a first fastening element provided on said first surface of said first web of said pressure distribution element, and a second fastening element provided on said outer surface of said tongue for engagement with said first fastening element.
  • a one-piece pressure distribution plate adapted to loosely fit in the leg opening of the boot between the opposed edge regions and having an inner surface and an outer surface;
  • the outer surface extending outwardly from the inner surface and adapted to extend loosely between the opposed edge regions of the boot so that when the boot is in the closed position the edge regions are spaced apart and abut against respective opposed sides of the outer surface and the inner surface is loosely gripped under both of the edge portions of the leg opening.
  • a pressure distribution element as specified in claim 6 further comprising means defining grooves on the sides of the outer surface adjacent both of the edge regions bounding the leg opening for receiving the edge regions therein when the boot is closed.
