Definitions

  • the present invention relates to a ski mountaineering kit, in particular, comprising a ski boot and a plate for attachment to the ski.
  • Ski mountaineering boots are known to comprise a shell, a sole, and a shank hinged to the shell at the ankle.
  • Ski mountaineering calls for boots capable of assuming a downhill position, in which, as with downhill ski boots when skiing downhill, both the toe and heel portions of the boot are clamped to the ski and the shank of the boot is fixed rigidly to the shell, and an uphill or walking position, in which only the toe portion of the boot is clamped and the heel portion is free, i.e. raised off the ski, to enable the ski to be dragged as in cross-country skiing.
  • Boots of this sort are normally made, like downhill ski boots, of substantially rigid plastic material, thus limiting the natural bending movement of the foot, particularly at the metatarsus-phalanx articulation, and causing discomfort when walking without skis or uphill with the skis attached.
  • Ski mountaineering boots are also known to be made of relatively soft plastic material, which, being flexible, allows a limited bending movement of the foot when walking uphill. Such boots, however, are not rigid enough to maintain the ideal downhill position.
  • a ski mountaineering kit comprising a ski mountaineering boot having a shell made of plastic material and which can be used together with a ski mountaineering clamp assembly comprising a front clamp for the toe of said boot, and a rear clamp for the heel of said boot; characterized in that said shell comprises a flexible portion extending crosswise to the shell, close to said toe and at the metatarsus-phalanx articulation; said kit comprising a supporting device attachable to the ski, behind and close to the front clamp, so as to be located, in use, beneath said flexible portion to prevent deformation of the flexible portion when the boot is secured to both said clamps.
  • Number 1 in Figure 1 indicates as a whole a ski mountaineering kit comprising a ski mountaineering boot 2 and a supporting device 3 attachable to a ski 4.
  • Ski 4 has a ski mountaineering clamp assembly 6 of the type described in Patent EP 0199098, and comprising a front clamp 7 and a rear clamp 8 separated from each other and both fixed rigidly to ski 4.
  • Boot 2 substantially comprises a shell 12 made of plastic material; a sole 13; and a shank 14 hinged to shell 12 at the ankle in known manner not shown.
  • Shell 12 comprises integrally a toe portion 15 from which extends an end flange 16 having two lateral seats (not shown) cooperating in known manner with front clamp 7 of ski 4 to substantially hinge boot 2 to ski 4 about an axis C; two lateral walls 17 forming a front opening (not shown) closed by a known tongue (not shown); and a heel 18 having a rear seat (not shown) cooperating in known manner with rear clamp 8 to clamp boot 2 to ski 4.
  • boot 2 is only secured to clamps 7, 8, with sole 13 a given distance off, as opposed to resting on, the ski.
  • Shell 12 also comprises a flexible portion 21 extending crosswise with respect to shell 12, from one side to the other of sole 13, and substantially located at the metatarsus-phalanx articulation of the wearer, i.e. close to the toe portion 15 of shell 12, so as to enable the foot to be bent for more comfortable uphill walking when the boot is only attached to front clamp 7.
  • flexible portion 21 has an undulated contour defined by two grooves 22 separated by a radiused intermediate projection 22a, extends obliquely to follow the natural bend axis of the foot, and has one end, on the inner side of boot 2, located forwards with respect to the other end on the outer side of boot 2.
  • Device 3 is attached to ski 4 just behind front clamp 7 (Figure 1) so as to define a support for sole 13 of boot 2, substantially beneath flexible portion 21 of boot 2.
  • Supporting device 3 comprises a base plate 25 connectable integrally to ski 4 by means of screws (not shown) engaging respective holes 26; and a top plate 27 fitted in sliding manner to base plate 25.
  • Plates 25 and 27 are conveniently made of material, e.g. plastic material, with as low a friction coefficient as possible, and at any rate lower than the friction coefficient between top plate 27 and sole 13, which is made of elastomeric material.
  • Plates 25 and 27 have respective sunken portions facing each other and together defining a shallow, substantially rectangular cavity 28.
  • Top plate 27 comprises, on the underside face, a central cylindrical projection 29 engaging in sliding manner a transverse slot 30 in base plate 25, and is secured contacting base plate 25 by a lock washer 34 located on the underside of base plate 25 and larger in diameter than the width of slot 30 ( Figure 4) so as to cooperate axially with a peripheral edge 36 of the slot.
  • the supporting device also comprises a spring 37 housed inside cavity 28 between plates 25 and 27, and in turn comprising an intermediate portion 38 wound about a pin 39 integral with base plate 25, and two arms 40 terminating with respective end portions 41 resting on opposite faces of a central stop projection 42 extending from base plate 25.
  • Pin 39 and projection 42 are located on opposite sides of slot 30, along the longitudinal center line of base plate 25.
  • Arms 40 of spring 37 are substantially V-shaped, so as to diverge and then converge with respect to each other, and intersect each other in an undeformed condition (not shown) of spring 37. In the assembly position shown in Figure 3, arms 40 are therefore preloaded against projection 42.
  • Top plate 27 also comprises a longitudinal underside rib 35 extending on longitudinally opposite sides of projection 29 and located between arms 40 of spring 37. Arms 40 tend to keep plate 27 centered and aligned with respect to base plate 25 in the absence of external loads; and slot 30 is conveniently defined by two branches 30a, 30b forming an obtuse angle with the vertex facing front clamp 7, so as to define, in use, a stable centered position of projection 29, and therefore of plate 25, by arms 40 interacting elastically with rib 35.
  • heel 18 In actual use, in the uphill position, heel 18 is free; boot 2 is only attached to front clamp 7; and flexible portion 21 allows the foot to bend naturally, particularly when walking without skis.
  • the boot provides for optimum performance both down- and uphill, by performing as though it were rigid and attached rigidly to the ski in the downhill position, and flexing and so assuming a more comfortable uphill position when released from the rear clamp.
  • the boot is also more comfortable for walking in.
  • device 3 comprising a base plate 25 connected integrally to the ski, and a top plate 27 movable with respect to the base plate, device 3, even when used together with an elastomeric sole, in no way impairs the safety of clamp assembly 6.
