Definitions

  • a device for releasably binding a boot and a ski comprising engagement means and locking means for engaging the engagement means, the locking means being adapted to releasably engage the engagement means in at least two successive positions and releas able from each of said positions in response to a predetermined applied energy.
  • the device provides for stepped release of the binder in response to different levels of shock experienced by the skier. Lower levels of potentially traumatic shock are absorbed by release of the locking means from its first position without physical release of the boot from the ski because of the continuing engagement of the locking means in its successive engagement position.
  • the device of this invention substantially eliminates or reduces this problem by providing a binder device with successive locking means, each responsive to a predetermined level of applied energy, so that lesser shocks can be absorbed by the mechanism without separation of the ski or loss of control by the skier.
  • FIG. 1 is a side elevational view partially in section showing a ski boot secured to a ski by an embodiment of the binder of the invention.
  • FIG. 2 is a view similar to that of FIG. 1 showing the release of the locking mechanism set at the lower predetermined shock level.
  • FIG. 3 is a top plan view, partially in section, taken along line 3-3 of FIG. 1.
  • FIG. 4 is a top plan, fragmentary view partly in section showing another embodiment of the invention.
  • FIG. 5 is a sectional view taken along line 5-5 of FIG. 4.
  • FIG. 6 is a fragmentary view showing complete release of the locking means of FIG. 4.
  • the invention provides a device for releasibly binding a ski to a boot by locking means adapted for binding engagement in at least two successive positions, each releasible at a predetermined level of applied energy which can be adjustably preset by the wearer.
  • locking means adapted for binding engagement in at least two successive positions, each releasible at a predetermined level of applied energy which can be adjustably preset by the wearer.
  • the ski In the event that the applied force exceeds the predetermined level of the releasible locking means in all of its positions, the ski is positively separated from the boot. In such case, the device has the advantage of absorbing a larger proportion of the applied energy because of its multiple releasible locking means.
  • the locking means comprises a plurality of separately activated locking means, each releasible at a predetermined level of applied energy.
  • the locking means comprises a releasible member, which. under a predetermined level of applied stress, is movable into successive locking positions or into complete disengagment.
  • ski as used herein broadly includes other devices secured to a boot or shoe which may require separation under applied stress, such as snowshoes.
  • the releasible locking means employed in the invention can be of a variety of designs, including conventional designs, so long as they are responsive to release at a predetermined level of applied energy and the predetermined levels can be adjustably preset for the locking means in each of its multiplicity of positions.
  • the locking means can, for example, comprise a plurality of individual locking elements, each comprising a spring-loaded, eccentric cam provided with a stud element which mates in locking engagement with a grooved or slotted engagement means.
  • the eccentric cam can be maintained in the desired locking position through the action ofa ball which is urged into a socket on the cam by the action of a spring, the tension of which is preset by an adjustment screw.
  • the locking means can be a pivotable member movable into successive locking positions in response to a predetermined level of stress.
  • the multi-step release binder device can be emi ployed to bind either the toe or the heel of the boot to the ski.
  • Lower wall 13 extends for a short distance forwardly of the side walls as shown.
  • Two separate locking means 14 and 15, vertically spaced from each other are seated inhousing 16 attached to ski 2 in ski recess 17 by attachment screws 18 inserted through openings in side flanges 18a.

Stud 21 extends into the upper part of slot 9 and is maintained in locking engagement therewith by ball 23 seated in mating cam recess 22, spring 25, which is in pressing engagement with the ball member, and adjustable threaded screw 26, which compresses the spring to the desired degree of tension. Communicating bores 27 and 28, the latter threaded, are provided in the housing for the spring and adjustment screw respectively.
  • Locking means comprises cam 29 pivotally mounted on pin 30 and provided on the side facing slot 9 with stud 31 and on the opposite side with recess 32. Stud 31 extends into the lower part of slot 9 and is maintained in locking engagement therewith by ball 33 seated in mating cam recess 32, spring 34 which is in pressing engagement with the ball member, and adjustable threaded screw 35 which compresses the spring to the desired degree of tension. Communicating bores 36 and 37, the latter threaded, are provided in the housing for the spring and adjustment screw respectively.
  • Cam 29 is additionally provided with a second stud 38 positioned below stud 31 and defining therewith a groove 39 adapted to receive extended wall 13 when cam 29 is in locking engagement with slot 9. Stud 38 is shorter than stud 31 and its side wall 40 defining groove 39 is inclined as shown.
  • locking means 14 and 15 are positioned in locking engagement with engagement means 4 as shown in FIG. 1.
  • Adjustment screws 26 and 35 are set to place springs 25 and 34 at desired predetermined degrees of tension, with that of spring 25 being preferably greater through it may be the same or less if desired.
  • cam 29 rotates to release stud 31 from locking engagement with engagement means 4 as shown in FIG. 2.
  • Ball member 33 is disengaged from cam recess 32 and, as the cam rotates, comes into engagement position with cam recess 41, which is provided as a convenient means for limiting the movement of the cam member after disengagement of stud 31.
  • a large proportion or all of the thrust to which the ski has been subjected is absorbed by release of locking means 15 and is, therefore, not transmitted via the boot to the wearer.
  • Locking means 14 remains in locking engagement with engagement means 4 but moves into the lower end of slot 9 because of the upward movement of the heel and attached engagement means when locking means 15 is released.
  • Stud 38 is provided as a convenient means for pushing cam 29 and attached locking stud 31 into locking position. Angled side 40 of stud 38 prevents binding of extended wall 13 in groove 39. The wearer can relock locking means 15 simply by pushing the heel of the boot downwardly to engage stud 31 in slot 9.
