Definitions

  • a baseplate has a vertical pivot pin on which a pivoted member is rotatably mounted, which is releasably interlocked with the baseplate and biased by a spring. which is concentric with the pivot pin and opposes a rotation of the pivoted member in both senses beyond an angle which is limited by the interlock.
  • a spring abutment is in screwthreaded engagement with the free end portion of the pivot pin and is held against rotation relative to the pivoted member but axially slidable relative thereto.
  • the pivot pin consists of a screw-threaded bolt, which has a head and is held in the baseplate so as to be displaceable in its axial direction.
  • the shank of the bolt extends through the baseplate and the pivoted member.
  • the end portion of the screw thread protrudes from the pivoted member and carries a nut, preferably a cap nut, and the head is accommodated in a recess on the underside of the baseplate.
  • the head forms a spring abutment for one end of the spring.
  • the other end of the spring bears on the bottom of the recess.
  • the nut which bears on the pivoted member can be turned to move the screw-threaded bolt in the axial direction so as to change the stress of the spring.
  • a toe iron for safety ski bindings which toe iron comprises a baseplate having a vertical pivot pin on which a pivoted member is rotatably mounted, which releasably interengages with the baseplate and is biased by a spring, which is concentric with the pivot pin and opposes a rotation of the pivoted member in both senses beyond an angle which is limited by the interlock
  • this object is accomplished according to the invention in that a spring abutment is in screw-threaded engagement with the free end portion of the pivot pin and is held against rotation relative to the pivoted member but axially slidable relative thereto, and the pivot pin is riveted in the baseplate as is known from other types of toe irons.
  • the initial stress of the spring can be changed in a simple manner in that the pivoted member is rotated through 360 about the pivot pin in the clockwise or counterclockwise sense, depending on whether the force required for a release is to be increased or decreased.
  • the pivoted member is large enough so that it can be turned by hand without need for a separate tool.
  • the pivoted member is lifted during a pivoted movement eliminate the interlock.
  • the pivoted member consists of two parts, one of which serves as a spring abutment and is nonrotatably mounted in the other part to be slidable in the direction of the pivotal axis and provided with at least one male detent, which cooperates with a corresponding female detent of the baseplate.
  • the spring abutment can be held against rotation by a nose, which is guided in a groove formed in the pivoted member and parallel to the axis thereof, which nose has a free end formed as a pointer, whereas the groove is formed as a slot in the range in which the spring abutment is adjustable, and said slot is provided with a scale at one longitudinal side.
  • the slot may be covered by a transparent cover.
  • FIG. 1 is a central longitudinal sectional view-showing a toe iron according to a first embodiment
  • a cap 7 is in screw-threaded engagement with the screw-threaded free end portion of the pivot pin 2 and serves as an abutment for a helical compression spring 8.
  • This helical compression spring lies in a recess 9 of the pivoted member 3 and is coaxial with the pivot pin 2.
  • the cap 7 has a nose 10, which enters a groove 11, which is formed in the pivoted member and is parallel to the axis thereof. The cap is thus held against rotation relative to the pivoted member but axially movable relative thereto.
  • the pivoted member 3 If the pivoted member 3 is under the action of a sufficiently large force which is transverse to the longitudinal axis of the ski, the pivoted member will perform a pivotal movement against the force of the helical compression spring and is constrained to move upwardly owing to its interlock with the baseplate. If the force does not reach the value required for a release or if a larger force acts only for a very short time, for example, as a result of shocks encountered during skiing, the interlock will not be eliminated so that the helical compression spring 8 can return the pivoted member 3 to its initial position when the force has decreased.
  • That end of the cap 7 which protrudes from the pivoted member 3 may serve to indicate the set force required for a release. It will normally be sufficient for the toe iron to enable a selection between four settings.
  • FIG. I shows the toe iron as set for the lowest force. Annular grooves are fonned in the cap to indicate this setting and the next higher setting. The third setting is indicated by the top edge of the cap. The fourth setting will be obtained if the central horizontal end face portion of the cap is flush with the surface of the pivoted member 3.
  • FIG. 3 shows a second embodiment of the toe iron according to the invention.
  • the toe iron comprises a baseplate 13, which is adapted to be connected to a ski by screws 14.
  • a pivot pin 15 is riveted into the baseplate. Different from the embodiment described before, the pivot pin does not have an external screw thread but a tapped hole 16.
  • the pivoted member consists of the two parts 17, 18.
  • Part 17 carries a soieholder 19, which in known manner, which will not be described in detail, is vertically adjustable for adaptation to soles differing in thickness.
  • a recess 20 of the part 17 of the pivoted member accommodates the part 18 of the pivoted member.
  • FIG. 3 shows the toe iron in the lowest setting. A rotation of the pivoted member causes the spring abutment 27 to be screwed down. This is apparent through the cover 31.
  • a toe iron particularly for safety ski bindings, said toe iron comprising: a baseplate; a pivot pin vertically mounted on said baseplate; a pivot member rotatably mounted on said pivot pin and releasably interengaged with said bascplate; a spring biasing said pivot member, said spring being concentric with said pivot pin; and a spring abutment cooperating with said biasing spring, in threaded engagement with the free end of said pivot pin, and axially slidable and nonrotatable relative to said pivot member.
  • said spring abutment has a nose guided in a groove formed in the pivoted member which groove extends parallel to the rotational axis thereof, said nose having a free end formed as a pointer, said groove being formed as a slot in the range in which the said spring abutment is adjustable, a scale defined on the longitudinal side of said slot against which said pointer is read,
  • said pivot member comprises a first part and a second part, said first part serving as a spring abutment; at least one male detent on said first part, at least one female dctent on said baseplate cooperating with said male detent, said first part being mounted in said second part, and being nonrotatable but axially slidable with respect to said second part.
