Definitions

  • the present invention relates to a ski boot structure particularly for downhill skiing.
  • ski boots which incorporate, internally of their soles or externally thereof, devices adapted for engagement with one or two binding members provided on the ski body.
  • Such prior devices usually comprise movable elements which engage with a snap action in recesses formed in the binding members owing to a pressure force exerted on said elements by elastic means, and specifically by spring means.
  • the binding member's recesses wherein such movable elements engage are provided on two opposed faces or areas of the binding member, and consequently, the movable members are located on opposed sides with respectto each otheron the binding member itself.
  • From DE-A-2329880 is known a ski binding and footwear combination particularly for cross- country skiing and convertible to downhill skiing, having a binding structure of the above type.
  • the binding member engages at a substantially central region of the boot and creates inherent problems due to the fact that all of the stresses resulting from the movements imparted to the ski by the skier while skiing are transferred through a single member, which makes it very difficult to calibrate the springs according to the skier's weight and skiing style or action, and according to the force required to release the ski from the boot in an optimum fashion in the event of the skier falling.
  • bindings have been developed which have two binding members rigidly attached to the ski body, see for example FR-A-2 051 109 wherein the recesses to be engaged by the movable elements are arranged to confront one another in spaced apart relationship such that the forces brought about to control the skis directionally are divided between both binding members and the moment of force which resists the force tending to release the ski from the boot can be made greater, thereby the springs of the movable elements do not require to be calibrated for maximum values, which reflects favourably on the reliable release of the ski from the boot in the event of a fall.
  • the aim underlying this invention is to obviate such prior drawbacks by providing a ski boot structure particularly for downhill skiing which can split the forces involved in securing the boot on a ski body in a different fashion.
  • Another object of the invention is to provide a ski boot structure which affords reliable releasing from a ski body in the event of the skier falling.
  • a not least object of the invention is to provide a ski boot structure having a sole which can be made shorter than the longitudinal extension of the boot shell in order to afford an improved ease of walking for the wearer.
  • a boot structure according to the invention as generally designated with the reference numeral 1, comprises a shell 2 whereto a sole 3 is rigidly attached and an inclinable leg part associated oscillably with the shell 2.
  • the sole 3 has internally mounted binding members, generally indicated at 5, which comprise at leastthree small plungers 6, 7 and 8 arranged to move coaxially with respect to each other within a guide 9 against and by the action of elastic means, specifically springs 10, accommodated in housings 5a, 5b, 5c.
  • the heads of the plungers are adapted for snap engagement with first and second binding blocks 11 and 12 respectively which are conveniently associated with the body of a ski 13.
  • the first plunger 7 and second plunger 8 are arranged such that their end heads confront each other and have a rounded shape to snap engage in seats 14 provided in the binding element 12.
  • the third plunger 6 has a rounded terminating head adapted to engage in a seat 15 provided in the binding element 11.
  • said small plungers 6, and 8 each have a tubular adjustment element 16, comprising an externally threaded stem 16a, threadably engaging a correspondingly threaded seat 16b, provided in the housings 5a-c, and having an enlarged extremity or thumb-wheel 16c, the rotation whereof causes the threaded portion to move the end of the spring 10 towards or away from the plunger 5, 6, 7 and is thus effective to calibrate the force exerted by the springs 10 according to the skier's requirements.
  • the binding members 5 also have associated therewith a lever system for moving the plungers 6, 7 and 8 manually, and which specifically comprises a first rod 17 passing through a tubular adjustment element 16 and being rigidly associated with the first plunger 7 and a second rod 18, rigidly associated with the second plunger 8, passing through an adjustment element 16. and having the opposed end thereof pivotally associated with a release lever 19 connected pivotally to the sole 2 approximately to the skier's heel.
  • calibration of the force exerted by the springs 10 in the housings 5b, 5c could also be achieved by providing a thread engagement relationship between the rods 17, 18 and the interior of the stem 16a of the adjustment element 16, and permitting the latter to slide in the seat 16b provided in the housings.
  • the first rod 17 has its free end journalled to one end of a small plate or link 20, in turn journalled to the sole 3, the opposed end of said plate being journalled to a first end of a bar 21 the other end whereof is pivotally connected to said release lever 19, so as to produce, on turning the release lever 19, simultaneous displacements of the plungers 7 and 8 in opposite directions and hence disengage the heads of the plungers from the binding element 12 and allow, therefore, the boot and accordingly the binding members associated therewith, to be separated from the ski body.
  • the sole 2 is advantageously provided with a cover element 22 having a circular opening 23 at the heads of the plungers 7 and 8 and a semicircular opening 24 at the plunger 6, adapted to define areas wherein the binding elements 11 and 12 are insertable.
  • the seats 14 of the binding element 12 are located diametrically opposed to each other and coaxial with the seat 15 in the binding element 11.
  • the binding block 12 is slideably movable along a guide 30, such that it can be moved towards and away from the binding block 11 according to the boot's size and therefore, the sizes of the hooking members provided in the sole.
  • the ski boot structure according to the invention is particularly advantageous in that it provides the skier with hooking members which have three small plungers, two of which, namely the plunger 7 and plunger 8, are in practice located close to the heel region of the skier's foot, in which region the greatest stresses are transferred between the boot and ski body, while providing on the binding block 11, i.e. close to the toe of the boot where stresses are much lower, a lower binding force effective to facilitate a possible release of the boot from the ski body in the event of the skier falling.
