Consequently, when a twisting torque is exerted on the skiers leg, the binding must release more readily than when a forward or backward torque is acting on the skiers leg. Therefore, the ideal binding should have different release characteristics depending on the direction of the torque exerted on the leg.

  • This binding 10 firmly holds the ski boot 14 to the ski 512 under normal conditions, but whenever a dangerously high torque exerts itself on a skiers leg, the binding 10 releases the connection between the pivot member and receiver 20, and the boot 14 with attached support member 16 separates from the ski l2 and attached receiver.
  • the binding releases in a lateral direction, either to the right or left depending on the direction of the torque. If an excess forward torque is exerted on the skiers leg, the binding 10 releases in the forward direction.

  • a skier secures his boot support member as follows: First, he places his boot 14 on the sole plate 22 and positions the heel 14a so that the cable 48 and encasing wire coil 52 of the rear grip 30 overlap the heel ledge 26 of the boot. Means may be provided for holding the rear cable 48' in position for receiving the heel ledge 26.
  • a plastic tab 64 having a looped upper end 66 receiving the coil 52 and cable 48 and a lower end 68 attached to the end 70 of the sole plate 22, biases the coil and cable 48 so that the heel ledge 26 fits easily thereunder.
  • the skier With the heel 14a in position and the sole 140 of the boot 14 resting square and flush with the top 22a of the sole plate 22, the skier sets the tip 60 of the handle 56 on the toe ledge 24, with the handle pointing generally away from the instep 14d of the boot 14. With the tip 60 serving as a fulcrum about which the handle 56 pivots, the skier then pulls the handle towards the boot instep 14d into the locking position, drawing the cable 48 and encasing coil 52 taut about the ledge 24 of the boot 14.
  • the skier To release the boot 14 from the grips 28 and 30, the skier simply moves the handle 56 away from the instep 14d to the unlocking position. This removes the tension on the cable 48 which now becomes slack. The skier then moves the handle and cable 48 away from the toe 14b of the boot 14 and steps off the sole plate 22.
  • the torque is not excessively high, there is insufficient torque to overcome the holding force of the springs 106 and 1 10 in the connectors and 82. If the torque is dangerously high, the twisting of the skiers booted foot turns the support member 16 laterally and the binding 10 releases.
  • the binding 10 is selective in that either operative socket 76 or 77 can act'as a fulcrum about which the pivot member 18 turns.
  • operative socket 76 or 77 can act'as a fulcrum about which the pivot member 18 turns.
  • the socket 76 will serve as a fulcrum for the pivot member 18, which turns clockwise when the twisting torque on the leg is twisting the leg clockwise.
  • the plunger 100 following the turning of the pivot member 18, is depressed and rides up the socket wall 77a to the rounded edge 77b.
  • the plunger releases its hold on the pivot member 18 and slides along the arcuate sidewall 18a of the pivot member.

  • the boot support member 16 disengages from the receiver 20.
  • the socket 77 will serve as the fulcrum about which the pivot member 18 rotates. This is illustrated in FIG. 8. Under these conditions, as soon as the socket 76 moves past the center line C of the ski 12, the boot support member 16 will be disengaged from the receiver 20.
  • forward or backward torque may be exerted on the skiers leg to cause the binding to release in either the forward or the backward direction as illustrated in FIGS. 9 and 10, respectively.
  • the torque exerted on the skiers leg will cause a release in a direction which is a combination lateralforward release or a lateral-backward release.
  • the binding 10 always selects and releases on the lower lateral setting. In other words, as soon as the lateral torque component exceeds the predetermined lateral torque limit, the binding 10 releases in the lateral direction. This is a unique feature of the present invention.

  • the boot support member 16 separates from the receiver in the backward direction. Again, a concurrent dangerous lateral torque would cause instantaneous release in the lateral direction.
  • the release of the binding 10 is controlled by (l) the magnitude of the forces exerted on the pivot member 18 by the spring-loaded plungers 98 and 100, and (2) the contours of the socket walls 74a, 75a, 76a, 77a. Adjusting the lugs 108 and 113 to control spring tension sets the holding force of the plungers 98 and 100.
  • a rounded contour at the edge of a socket wall permits a plunger to ride smoothly up and over this rounded edge. If the edge is highly rounded, a relatively small torque on the leg will cause the binding 10 to release. If the edge is sharply defined, i.e., is not rounded or rounded only slightly, only a relatively large torque on the leg will cause the binding 10 to release.
  • the tension of the springs 106 and 110 and the contours of the sockets 76 through 77 are controlled so that in the forward or rearward directions, the binding 10 releases when the leg is subjected to about 1,200 inch-pounds of forward or backward torque, and, in the lateral directions, the binding 10 releases when the leg is subjected to a twisting torque of about 360 inch-pounds.

  • edge extremities 76g and 76h are reversed.
  • binding 10 would release in the backward direction more easily.

If a dangerously high clockwise twisting torque as viewed in FIG. Sis exerted on a skiers leg, the plunger 98 rides over edge extremity 76 If a high counterclockwise twisting torque acts. on the leg, the plunger 98 rides over edge extremity 76i. High twisting torques of equal magnitude but opposite direction will cause release of the binding .10 in the lateral directions. For such lateral release generally it would not be recommended to have the extremities 76i and 76j rounded differently, because then the binding 10 would release in one lateral direction more readily than the other lateral direction.
  • edge extremities 76g and 76h i.e., the forward and backward release contours.
  • the edge holding power of the binding 10 is not related to the edge extremities 76and 76j which govern lateral release. Consequently, in sharp turns the binding 10 will not had vertently release.
  • each socket 74 through 77 is designed to have different release characteristics, the skier has great latitude in selecting what will be the release conditions of the binding 10.
  • the skier can select the conditions under which the binding 10 will release to match his skill and style of skiing. Skiers who tend to set back on their heels require the forward plunger 98 to hold more firmly than the rear plunger. Consequently, the socket 76 will be located opposite the forward plunger 98 as shown.
  • the binding 10 actually has two lever arms, a simple lever arm and a compound lever arm.
  • the simple lever arm has a length equal to the distance between sockets 76 and 77, i.e., l.53 inches.
  • the compound lever arm comprises a lever arm having a length equal to the distance between the end of the connector at which the boot support member pivots and the socket 76, and a lever arm having a length equal to the distance between the end of the connector at which the boot support member pivots and the other socket 77.
  • the lengths of these two lever arms will be about 6 and about 4 inches, i.e., the compound lever arm has an effective length of about 5 inches.
  • the binding 10 In addition to inherent saftey, three other important advantages are realized because of the short lever arm employed in the binding 10: (1) the boot support member 16 and the receiver 20 can be connected by a side entryway technique, (2) the binding inherently has excellent recovery from shocks, and (3) the binding provides reliable release under icing or other adverse conditions.
  • the side entry connection between the boot support member 16 and the receiver 20 is highly desirable. For example, if the ski boot 14 with boot support member 16 separates from the receiver 20 as described above, the skier, after recovering from his fall, is faced with the problem of reconnecting the boot support member 16 and receiver 20. With the binding 10, the skier reconnects the support member 16 and receiver 20 by a side entry technique. He first positions his leg and booted foot with attached boot support member 16 in the receiver 20 so that the plunger 100 mates with the socket 77 such as shown in FIG. 3. In the alternative he may mate the socket 76 with the front plunger 98. Next the skier rotates or twists his leg and booted foot sideways, moving the pivot member 18 sideways through the open side 86a of the gap 86.
  • the skiers leg muscle power is sufficient to overcome the force of the springs 110 and 106.
  • the plunger head 102 rides over the arcuate sidewall 18a of the pivot member 18, readily depressing the springs 110 and 106.
  • an ad- 10 ditional turn aligns the plunger with the socket 76 and the head 102 snaps into mating engagement with the socket 76. This operation cleans any snow from the pivot area and from between the boot support member 16 and the receiver 20 mounted on the ski.
  • the good recovery of the binding 10 is best illustrated by the following example. Assume a ski glances against the side of a mogul, and the skiers leg sustains a momentary blow which causes the boot support member 16 to turn to the position shown in FIG. 7. If
  • the blow only moves the support member 16 to this position and no further, it is still connected to the receiver 20.
  • This position of the boot support member 16 and receiver 20 is the threshold position. Any further clockwise rotation of the support member 16 will result in the release of the pivot member 18 from the grip of the plungers 98 and 100.
  • the spring 110 which normally urges the plunger 100 towards the pivot member 18 automatically reinserts the plunger into the socket 77 if the plunger 100 isnt too close to the edge 77b, or the skier may provide an assist by simply turning his foot counterclockwise as viewed in FIG. 7. It should be noted that the more ellipsoid the edge 77b the greater the degree of recovery.
  • FIG. 14a diagrammatically shows a lever arm X equal to approximately the distance between the toe and heel of a ski boot. If the binding is designed to permit the boot support member to pivot at Z so that v the toe end can move l/ 8 of an inch to either side of the center line C of the ski 12 prior to release of the binding, an l/8 of an inch is the maximum lateral recovery.
  • FIG. 14b diagrammatically illustrates the 2 inch lever arm employed in the binding 10.
  • the socket 77 serves as the fulcrum for the lever arm, and the sidewall 76a of the socket 76 is contoured such that the pivot member 18 can pivot l/ 8 of an inch to either side of the center line C of the ski 12 without releasing the binding 10.
  • the toe end of the boot support member 16 will move approximately /2 inch to either side of the center line C without releasing the binding 10.
  • the boot support member 16 can rotate through a greater are without releasing the binding 10, and consequently, lateral recovery is greater than with bindings employing long lever arms.
  • a high degree of lateral recovery is de- '1 1 sirable to avoid inadvertent release.
  • the skiers leg must overcome the holding force at the toe to accomplish release of the binding. If the release mechanism at the toe is set to hold the toe too strongly, the skiers leg will be injured before release is achieved. This could be done intentionally by the skier setting the release mechansim to hold the toe very firmly so that shock loads wont cause an unwanted release, or ice could accumulate at the toe to exert additional holding force at the toe. The shorter the lever arm the easier it will be for the skier to achieve release under such conditions.
  • the holding force at the toe preferably should not exceed 30 pounds.
  • the skier inadvertently sets the release mechanism at the toe for 35 pounds, 5 pounds in excess of the preferred limit.
  • the skiers leg will be subjected to 420 inch-pounds before the binding releases. That is, every one pound excess force at the toe subjects the skiers leg to 12 inch-pounds of additional torque. This is a highly dangerous condition. Contrast this with the binding 10.
  • the 2 inch simple lever arm dominates the release of the binding 10.
  • the force required to prevent lateral movement of the pivot member 18 in the receiver 20 is 180 pounds. This force is controlled by the spring tension and contour of the sockets 74 through 77. If the skier inadvertently sets the adjustment screws 113 and 108 so that the force is 185 pounds, the skier only subjects his leg to an additional 1O inch-pounds increase in torque. In other words, every pound of excess force exerted by the one plunger only subjects the skiers leg to an additional 2 inch-pounds of torque. This relatively small increase in torque can ordinarily be withstood without any danger of injury to the leg.
  • the holding force for example, at the toe preferably should not exceed 100 pounds. If the holding force is 5 pounds in excess of the desired force, the leg is subjected to 60 pounds of additional torque before release occurs. In my binding 10, when the leg is subjected to a backward or forward torque, the compound lever having an effective 5 inch length dominates.
  • the force required to prevent vertical movement of the pivot member 18 in the receiver 20 is about 240 pounds. Again spring tension and the contour of the sockets 74 through 77 control this force. If the skier inadvertently sets adjustment:
  • the pivot member and connectors could have alternate configurations, but in accordance with the present invention, the operative sockets of these alternate configurations would still be under the arch A of the boot 14.
  • the socket and the plunger heads instead of being hemispherical, may be conical, parabolic, or other configurations such as shown in FIGS. 15, 16 and 16a
  • the binding 121 illustrated in FIGS. 15, 16, and 16a includes a pivot member generally having an hourglass-like configuration with an aligned pair of sockets 122 and 124.
  • the sockets 122 and 124 are open at their:
  • tops have chamfered bottoms 122C and 124C, respectively, and angulated edges 122a, 122b, and 124a and 124b, respectively, in sockets 122 and 124.
  • Screws 126 secure the pivot member 120 to the underside of the sole plate 22, directly under the arch A of the boot 14. Consequently, the sockets 122 and 124 are in the proper position beneath the arch A. Under normal load,
  • a pair of spaced connectors 128 and 130 firmly hold the pivot member 120.
  • These connectors 128 and 130 are secured to the ski 12 by screws.
  • the underside of the sole plate 22 rests on the top of the connectors 128 and 130 when the pivot member 120 is coupled to the connectors 128 and 130.
  • the connectors 128 and 130 are identical and only one connector is shown in detail.
  • This connector 130 has an internal T-shaped chamber 140 which receives the T-shaped plunger 138.
  • the plunger 138 has at its base a pyramid-like nose 142 (FIG. 16a) adapted to engage the socket 124, and, as shown in FIGS. 15 and 16a, the nose 142 has a chamfered underside 144 which mates with the chamfered bottom 1240 of the socket 124.
  • There is a generally rectangular chamber 146 in the body of the plunger 138 which receives a flattened, coiled spring 148. One end of the spring 148 rests against the chamber terminal 152 and the other end engages a stop 154.
  • a screw 158 which has a ball end which fits into a recess 160 in the stop 154 passes through a rear wall 162 of the connector 130. This screw 158 adjusts the tension of the spring 148. Because of the general T shapes of the plunger 138 and the chamber 140, there are mating shoulders 164 and 166 which limit the movement of the plunger 138 in the direction towards the pivot member 120. The spring 148 normally urges the plunger 138 into mating engagement with the socket 124, and when the load conditions are such that the pivot member 120 turns in any direction, the plunger 138 is depressed and the nose 142 glides over the chamfered edges 124a and 124b, releasing the pivot member 120 so that the ski boot can separate from the ski 12.
  • the socket 124 By controlling the angle at which the edges 124a and 124b adjoin, and the angle of the chamfered bottom 1240, the socket 124 will have a characteristic edge or surface contour adapted to disconnect the pivot member 120 and connector 130 under predetermined load conditions.
  • the plunger ends or noses may be of a conical configuration with complementary receiving sockets also of conical configuration. Applicant has tested such an alternative configuration embodying cone angles of approximately 90 and has found that the operation is fully satisfactory. Such a conical arrangement has certain advantages of simplicity in that release characteristics can be readily changed by changing the depths of the sockets and/or the conical angles of the plunger noses and the mating sockets.
  • pivot members 18 or 120 could be secured to the ski 12 and the pairs of connectors 8082 or 128-130 could be secured to the sole plate 22 or 22.
  • This alternate arrangement would be fully equivalent to the structures shown in FIGS. 1 through 9 and FIGS. 15 and 16, provided the spatial relationships between the pivot members 18, 120 and their respective connectors 80, 82 and 128, 130 remains the same.
  • FIG. 17 Another alternate embodiment of the present invention is shown in FIG. 17.
  • the sole plate is eliminated and a boot 200 is designed to coact with pivot member 18' secured to the ski 12.
  • the pivot member 18' is identical in construction with that shown in FIGS. 1 through 6 except it is secured to ski 12 rather than to a sole plate.
  • the boot 200 has a recess portion 201 defined by two spaced apart sole portions 202 and 204. Secured within these sole portions 202 and 204 are connectors 80 and 82, respectively.
  • the pivot member receiver is integral with the boot 200 rather than being secured to the ski 12. It is critical that the recess 201 be directly beneath the arch A of the boot 200. This recess is adapted to receive the pivot member 18' in the same manner as the gap 86 (FIG.

  • the plungers 98 and 100 coacting with the pivot member 18', hold the boot 200 secure to the ski 12 under normal load conditions.
  • the boot 200 pivots about the pivot member 18, depressing the plungers 98 and 100 so that these plungers pop from the sockets 76' and 77' and release the connection between the boot 200 and the ski 12.
  • the boot 200 is adapted to release in the forward, backward, lateral, or combined directions as described above.
  • a ski boot 249 includes a recess portion 250 defined by two spaced sole portions 252 and 254.
  • the recess 250 is directly beneath the arch A of the boot 249.
  • the sole 251 of the boot 249 has a surface made of an anti-friction material such as a fluorocarbon polymer dispersed in a ceramic.
  • an anti-friction material such as a fluorocarbon polymer dispersed in a ceramic.
  • a specially designed pivot member 256 is secured by screws 258 to the ski 12.
  • This pivot member 256 has an enlarged central opening 271 with two bores 260 and 262 generally at right angles to the opening 271 and aligned with each other.
  • a pair of plungers 264 and 266 extend, respectively, through the bores 260 and 262.
  • the plungers 264 and 266 are similar to each other and similar to plungers shown in FIG. 4.
  • Plunger 264 includes an internal chamber 265 which receives one end of a coiled spring 268.
  • a snap ring 270 fits into a groove in the side wall of the bore 260 and a seal 272 adjacent this snap ring prevents grit and moisture from entering the central opening 271.
  • a bushing 273 surrounds the plunger 264, and a snap ring 276 in a groove in the side wall of the plunger 264 pushes against the bushing as the spring 268 urges the plunger 264 outwardly through the bore 260.
  • the snap ring 270 prevents the plunger 264 from popping out of the bore 260.
  • the main difference between the plungers 264 and 266 is that the plunger 266 has a removable head 280 including a hexagonal nut 282 formed in the wall of the head and a rounded tip 284.
  • the head 280 is adapted to be screwed into a threaded end of a chamber 286 in the plunger 266.
  • the other end of the spring 268 fits into this chamber 286 and abuts a number of compression rings 288 disposed in the chamber.
  • To insert the spring 268 or add or remove compression rings 288, the head 280 is simply removed.
  • the compression rings 288 control the tension of the spring 268. As' more compression rings 288 are included in the chamber 286, the tension in the spring 268 increases, and vice versa.

  • a snap ring 290 in a groove in the side wall of the bore 262 coacts with a bushing 292 surrounding the plunger 266 and a snap ring 294 fitted into a groove in the side wall of the plunger to prevent the plunger 266 from popping out of the bore 262.
  • a pair of sockets 300 and 302 coact with the plungers 264 and 266, respectively, to releasably hold the ski boot 249 to the ski 12.

  • either the plunger 264 or 266 or both are depressed when the boot 249 begins to turn laterally or pivots forward or backward off the toe or heel. Assuming the plunger 264 is depressed, this plunger moves toward the central opening 271, depressing the spring 268. As soon as the plunger 264 clears the socket 300, the spring 268 will force the plunger to return to the position shown in FIG. 19, where the bushing 273 abuts the snap ring 270, and the snap ring 276 abuts the bushing.
