Definitions

  • the toe iron comprises a pivoted member, which is rotatable against the force of at least one spring about a pivot pin, which is at right angles to the surface of the ski and which is held on a baseplate secured to the ski.
  • the pivoted member carries a soleholder member, which is also rotatable about a pivot pin which is at right angles to the surface of the ski and when the toe iron is in normal position the soleholder member is engaged on both sides of the longitudinal center line of the toe iron.
  • the soleholder member bears on the pivoted member and by means of another pivot pin and a pivoted lever is linked to the pivoted member.
  • the pivoted lever consists of a twoarmed lever and that arm which does not carry the soleholder member is formed with a slot, by which the lever is mounted for rotation and for a sliding movement in the longitudinal direction of the lever in a vertical pivot pin, which is also held on the baseplate, all pivot pins lie on the longitudinal center line of the toe iron when the latter is in its normal position, and the maximum distance between the two pivot pins for the pivoted lever is less than the distance between the two pivot pins secured to the baseplate.
  • soleholder member is supported on both sides of the longitudinal center line of the toe iron by means of respective pins, which engage noses formed on the baseplate.
  • the safety ski binding comprises a heel-holding device, which forces the skiing boot against the toe iron in order to ensure a satisfactory control of the ski.
  • a lateral pivotal movement of the soleholder imposes on the toe iron a simultaneous component of movement towardthe tip of the ski within the so-called elastic zone.
  • the inventor has conceived the object to design a toe iron of the kind previously described so that the skiing boot cannot move to theitip of the ski within its elastic zone so that a return of the skiing boot to its normal position
  • a toe iron for ski bindings which-toe iron comprises a pivoted member, which is rotatable againsttheforce of at least one spring about a pivot pin, at right angles to the surface of the ski and which is held on a baseplate secured to the ski.
  • the pivoted member carries a soleholder member, which is also rotatable about a pivot pin that is at rightangles to the surface of the ski and when the toe iron is in normal position the soleholder member is engaged on both sides of the longitudinal center line of-the toeiron.
  • the soleholder member bears onthe pivoted member and by means of anotherpivotpin and a pivoted lever isilinked to the pivoted member.
  • The-pivoted lever consists of a two-armed lever and that arm which does not carry the soleholder member is formed with a slot, by which the lever is mounted for rotation andfor a sliding movement in the longitudinal direction of the lever in a vertical pivot pin, which is also held on the baseplate. All pivot pins lie on the longitudinal center line of the toe iron when the latter is in its normal position, and the maximum distance between the two pivot pins for the pivoted lever is less than the distance between the two pivot pins secured to the baseplate.
  • the spring consists of a compression spring, which is held between the outwardly extending arms of the bellcrank levers.
  • the baseplate is provided with two stops, each of which is associated with one of the last-mentioned arms of the bell-crank levers and limits the outward pivotal movement thereof, and the free ends of the inwardly extending arms of the bell-crank levers form noses for retaining the pivoted member.
  • the retaining noses of the bell-crank levers may act on the pivot pin which connects the pivoted lever to the pivoted member.
  • a tension spring connected between the two pivot pins for the pivoted lever may serve as a spring for the toe iron.
  • FIG. I is a central longitudinal sectional view showing a toe iron
  • FIG. 2 is a sectional view taken on line Il-Il in FIG. I showing the toe iron and FIGS. 3-5 are top plan-views showing the toe iron in different stages of the releasing operation.
  • the toe .iron for safety ski bindings which is shown on the drawings comprises a baseplate 1, which is adapted to be connected by screws to a ski, not shown, and for this purpose has two countersunk holes 2, 3.
  • the baseplate is provided with a vertical pivot pin 4, on which a pivoted member 5 is rotatably mounted/This pivoted member has the configuration of a triangle which is rounded at the corners (see particularly FIG. 2).
  • a vertical pivot pin 6 is provided at that corner of the pivoted member 5 which normally points to the tip of the ski and a pivoted lever is rotatably mounted on the pivot pin 6.
  • This pivoted lever consists of a two-armed lever and at its arm 7 normally directed to the butt end of the ski carries by means of V a pivot pin 8 a soleholder member 9.
  • This soleholder member is freely rotatable on the pivot pin 8 and in its portion opposite to the pivoted'member 5 has a recess 10 (see particularly FIGS. 1 and 2) so that when the toe iron is in position for skiing the soleholder will always bear at two points against the t pivoted member 5 and is normally held against a pivotal movement about the pivot pin 8.
  • the soleholder member On its side facing the skiing boot, the soleholder member is concave to receive the toe portion of the sole and has a lip for engaging the top of the sole.
  • the soleholder member may be arranged in known manner, which is not shown and not specifically described, so as to be adjustable to soles differing in thickness.
  • the second arm 11 of the pivoted lever extends normally to the tip of the ski and has a vertical slot 12, by which the lever is guided on a pivot pin 13,
  • the force required for a release of the toe iron cannot be changed.
  • one spring abutment is arranged in known manner to be adjustable in the longitudinal direction of the spring.
  • the pivoted member 5 is provided with a corresponding transverse groove 21.
  • the baseplate l carries adjacent to the pivot pin 13 a spacer 22, which has the same thickness as the lower wall with which the pivoted member 5 defines the groove 21 (see FIG. 1).
  • the toe iron is shown in its normal condition, ready for ski ing, in FIGS. 1 and 2.
  • pivot pins 4, 6, 8, I3 lie on the longitudinal center line of the toe iron.
  • a force in excess of the initial stress of the helical compression spring 16 acts on the soleholder member 9, e.g., in the direction of the arrow 23 (see FIG. 2), which is transverse to the longitudinal direction of the ski, this force will cause the soleholder member to move against the progressively increasing force of the spring on an are having a center of curvature adjacent to the heel of the skiing boot.
  • FIG. 3 shows the toe iron with the soleholder member which has been swung out to some extent.
  • the movement of the soleholder member in accordance with the radius of the pivotal movement of the skiing boot is accomplished in that the pivoted lever 7/11 is moved toward the skiing boot during the movement of pivoted member.
  • the movement of the pivoted member 5 results at the same time in a pivotal movement of the soleholder member 9, which bears on the pivoted member, about the pivot pin 6.
  • the helical compression spring 16 Upon a decrease of the force which acts on the soleholder member in the releasing sense, the helical compression spring 16 returns the soleholder member to its normal position.
  • FIG. 4 shows the toe iron in its instantaneous position shortly before the release-initiating position has been reached.
  • the soleholder member 9 can perform a virtually free outward pivotal movement about the pivot pin 8, as is shown in FIG. 5. This action enables a reliable and fast release of the skiing boot from the toe iron.
  • the spring 16 automatically returns the toe iron to its normal position so that the toe iron is immediately ready for skiing.
  • the soleholder member 9 moves about an imaginary pivotal axis of the skiing boot.
  • the skiing boot does not perform a movement toward the tip of the ski so that it will not move toward the butt end of the ski during a return pivotal movement; such movement toward the butt end of the ski would have to be performed against the contact pressure produced by the heel-holding device.
  • a toe iron for ski bindings comprising a baseplate, a first pivot pin secured to said baseplate, a pivoted member rotatably mounted to said pivot pin, a second pivot pin secured to said pivoted member, a two-armed lever member rotatably mounted to said second pivot pin, said lever member having a pivot pin on one arm and defining a slot on the other arm, a third pivot pin secured to said baseplate and extending into said lever member arm slot, allowing said lever member to rotate and slidably move along said slot, a soleholder member, said soleholder being pivotally mounted to said one arm by said pivot means, a rearward portion of said pivoted member being in abutting contact with a forward portion of said soleholder, spring means biasing said pivoted member in a normal toe holding position and maintaining all of said pivot pins in the longitudinal center line of the toe iron, with the maximum distance between the second and third pivot pins being less than the distance between the first and third pivot pins secured to the baseplate.
  • a toe iron for ski bindings comprising a baseplate defining stop means, a first pivot pin secured to said baseplate, a pivoted member rotatably mounted to said first pivot pin, a pivot pin secured to said pivoted member, a pivoted lever rotatably mounted to said pivoted member pivot pin, said pivoted lever having two arms, one of said arms defining a longitudinal slot and the other arm carrying a pivot pin, a soleholder member carried by and rotatable on said pivoted lever pivot pin, said soleholder bearing against said pivoted member at at least two points and held against pivotal movement about said pivoted lever pivot pin when in normal position a second pivot in secured to said baseplateand extending into said pivoted ever arm slot to guide said pivoted lever,
