Definitions

  • a spheroid (3) into which two retaining arms (39) and a positioning leg (2) are fixed, and whose rear has a shaped recess (36), is mounted in a cylindrical container (34).
  • the container's closed end is hemispherical. It has a slot (I) and a shaped aperture (38) cut in it, to allow limited movement in any direction of the ski-boot's two retaining arms, and up and down movement of the positioning leg.
  • the arms and leg move, due to forces acting on them, via the welts and sole of the ski-boot. They can only move because the spheroid rotates in its container.
  • a spring-loaded (20) plunger (48) is in three sections, two of which are concentric (10) (13), locked together by inserts (14).
  • the seal is forced against the walls of the containing cylinder (49), by the action of the release spring. Rotation of the spheroid can only occur, because of a relative displacement between the spheroid, and the plunger, against the release spring (20). Sufficient rotation will take the plunger outside the constraint of the shaped recess (36).
  • the inserts (14) are locked in place by a shaped piston (30).
  • the rear part of the plunger also forms a piston (25).
  • This fluid will either flow through the restrictable by-pass, formed, by the control rod (22), and the ports (18) (17) in the shaped piston (30), and plunger (13), or, if the flow is too great, it will cause displacement of the shaped piston (30), against its return springs (8) (21).
  • Momentary changes in volume, as the shaped piston (30) moves, is compensated for, by inflation of the compensating bag (29).
  • the Mechanical Release Unit (Fixed), is similar in its action to the Mechanical Release Unit described in para 2.2.1., in that release forces, acting on the retaining arms (39) and positioning leg (2), will cause the spheroid (3) to rotate. Because the plunger (4) is fixed, rotation of the spheroid can now only occur, by the spheroid and its container being displaced away from the plunger, by compressing the relatively light spheroid casing return spring (41). This displacement, will be transmitted through the ski-boot, to the Mechanical Release Unit, against its release spring. It will cause release of the constraint of this spring, either as described in para 2.2.1., para 2.2.4., or by the rotation of the spheroid, taking the fixed plunger (43) (4), outside the limit of the shaped recess (36).
  • the release spring (20) tension is set, by adjusting the retaining cap (24). Displacement of fluid due to adjustment, is taken up, by the compensating bag (29). This control is pre-set, according to the physical properties of the skier.
  • Control over the rate of increase in release force is set, by controlling the rate at which fluid can be displaced, by the piston part of the plunger (25), through the by-pass ports (17) (18). It is set by adjusting the position of the control rod (22), to set the by-pass dimensions according to the physical properties of the skier.
  • Mannual Release is achieved by sliding the release unit housing (47).
  • the release unit housing is coupled to the piston (30), by the connecting rod (46) acting through the mounting block (5), the spring (8), and fluid seal (32). Sliding the housing will displace the piston (30), until the second shaped portion (50), allows the inserts to unlock the two concentric portions of the plunger from each other, and thus remove the release spring's influence on the spheroid's rotation.
  • the spheroid can thus move the plunger, against the relatively light return spring (16), so that the retaining arms no longer retain the ski-boot.
  • the Binding consists of a front and rear unit, at least one of which is a Mechanical Release Unit.
  • the second unit is either a Mechanical Release Unit (Fixed), or another Mechanical Release Unit, depending on the experience of the skier.
  • Either the Mechanical Release Unit, or the Mechanical Release Unit (Fixed), can be in the Front or Rear position.
  • the Compensating Bag is a non-permeable, elastic bag (29), filled with a permeable, sponge-like material (26), which will allow changes in pressure and volume inside the fluid container, to balance against atmospheric pressure. It is secured to the casing (49) by a grub scew (28) and washer (27) which are drilled to allow atmospheric compensation.
  • Compensating Ports (II) are drilled through applicable moving components to facilitate a free flow of fluid when these components move and to prevent seepage having a detrimental effect.
