  • (6) is a crank mechanism holding frame with a cross section of about II like shape having vertical walls (a)(b) at both sides and being held and inserted in said guide grooves (29) in such manner as being slidable along the groove (29).
  • the hole (7) is of an almost triangle shape and consists of, as shown in FIG. 4, an upper side (20), an oblique side (23) and an almost vertical side (13).
  • a pair of connecting swing cranks (11) in each one of which an arc shape release guide groove is perforated are axially fixed at both sides between the vertical walls (a) and (b) of the holding frame (6) by a second crank axle (12).
  • one end of a pull-up arm metal (3) is axially fixed between said pair of connecting swing cranks (11) by a first crank axle (4), and the other end of this pull-up arm metal (3) is axially fixed to a lever metal (1) through a crank connecting axle (2).
  • This lever metal (1) is further axially fixed at outer sides of said holding frame (6) by an activating rotatary axle (l9).
  • (9) is a slide crank pin which is inserted through guide holes (7) perforated at both sides of the holding frame (6) and through the'guide groove (10) perforated in the connecting swing crank (11), and a spring (5) is provided between said crank pin (9) and the part where the lever metal (1) is installed, wherein the crank pin (9) is always pressed forward by elastic power of this spring (5).
  • (30) is an adjusting screw to adjust the elasticity of the spring (5).
  • (16) is a release crank which has an external wall (17) and a concave groove (14) at its top surface, and is inserted in a freely slidable manner in an almost vertical hole (15) provided in the lever metal (1), and this release crank (16) has at its lower part a long hole (36) and an axle hole (35) as shown in FIG. 8.
  • the above-mentioned activating rotatary axle (19) is freely supported in said long hole (36), while the axle hole (35) supports both ends of the sliding crank pin (9).
  • (24) is an auxiliary spring for pushing up the lever metal (1).
  • (l8) and (21) are a step on tongue plate and a heel holding metal respectively attached to the front part of the lever metal (I).
  • This position adjusting screw (31) is a position adjusting screw which is axially attached to a fixed member (32).
  • This position adjusting screw (31) engages with a screw thread (33) provided on the above-mentioned base plate (26), and the fixed member (32) can be shifted and adjusted to the long way of ski bench by rotating said screw (31).
  • this fixed member is freely inserted in a groove (34) provided in the above-mentioned holding frame (6), and said fixed member (32) and the holding frame (6) are elastically connected together by a spring (22), wherein the ski boots are held in place in a long way of ski by said elasticity.
  • the connecting axle (2) which axially hold the pullup arm metal (3) is positioned at its lowest point, and the slide crank pin (9) completes the piston movement by the elasticity of the spring (5) and is completely compressed to an end part (8) of the outside guide hole (7), thus the ski boots will be placed in such state as being pressed onto the ski bench with the maximum fixthe retreating stress spring (22) shown in the drawing at the same time as the step-on action for fixing ski boots, and when fixed this pressure working to front direction by the retreating stress spring (22) works to press the ski boots against any given toe holding metal, thus multiplying said fixing force.
  • fixing function of ski boots can be easily achieved by stepping on the step-on tongue plate (18), furthermore as a result of said step-on action, a complete fixing force can be given to the ski boots along with any given toe metal, thus a complete and safe fixing of ski boots can be achieved.
  • the compressive force by the transposition of the spring (5) which is generated by the shifting of the slide crank pin (9) from its extreme front part (8) to a retreat rest groove provided at the extreme retreat position controls the rotatary movement to upward direction of the pull-up arm metal (3), that is the rotating movement of the lever metal 1) around the activating rotatary fulcrum (19), thus eventually controlling the degree of release safety device of the metal binding for heel of ski boots according to the present invention.
  • the lever metal (1) which has been pulled up by such large external force as mentioned above makes the pull-up arm metal (3) which is connected thereto to function as the force to restrain the heel of ski boots until the arm (3) passes its dead point, then after passing the dead point it completely turns round and automatically releases the lever metal (1) and makes it jump up by the reversal of the working point of the compressive power of the spring (5) and the working direction.
  • the ski boots are released from hazardous external force and a skier is protected from injury on legs and other parts of body by said external force and his safety is secured, thus the function of the metal binding for the heel of ski boots of the present invention as a safety device to protect a skier is proved.
  • crank pin (9) at this time moves downward sliding along the release guide groove (10) perforated on the connecting swing crank (11), further, at the same time the crank pin (9) is slided downward along the oblique side (23) of the outside guide hole (7) provided at the crank mechanism holding frame (6), therefore the crank (11) rotates to counter clockwise direction around a fulcrum of the second crank axle (12).
  • the descending distance of the release crank (16) should be such distance that the magnitude of the cam efficiency being generated as being transmitted from the spring (5) which works to push the pull-up arm metal (3) downward becomes smaller than the force of the release spring (24), and as the descend ing distance decreases it helps to reduce the force given to the release crank (16) being required for its release action.
  • the metal binding for heel of ski boots has, along with the above-mentioned advantage, such advantage as securing complete fixing action for sliding with ski by simple step on action and action of the safety device to protect human body from unexpected external injury which works instantaneously against hazardous external force, thus this metal binding has totally ideal function having great practical value.
  • the fixing mechanism of metal binding according to the present invention can be shifted to the long way of ski bench by rotating the screw (31 thereby the position of said metal binding can be adjusted according to the size of ski boots to be fixed so that ski boots of any size can be surely fixed.
  • a ski boot heel binding device comprising a base plate fixedly mounted on a ski, a holding frame, means mounting said holding frame on said base plate for movement in the longitudinal direction of the ski, heeling engaging means pivotally mounted on said holding frame, said holding frame having means defining an opening, swing crank means pivotally mounted on said holding frame, a lever having one end portion pivotally mounted on said swing crank means and the other end portion pivotally mounted on said heel engaging means, means defining a groove in said swing crank means, said groove being generally aligned with said opening in said holding frame, a slide crank pin carried in and freely slidable along said aligned groove and opening, spring means biasing said slide crank pin in a direction towards the heel of the ski boot, whereby said spring means is operative to urge said heel engaging means in either one of two pivotal positions wherein in one position, the ski boot heel is engaged and in the other position the ski boot heel is released, and a release means mounted on said slide crank pin and operable to be manually actuated to pivot said heel engaging means from its heel engaging to its heel
