- the ski boot comes loose when sufficient pressure is applied to the mechanism.
- the device has a cocking action and also includes the fine adjustment consisting of the member 64 that engages the lug 58.
- the spring serves to provide proper tension or pressure on the jaws 84 so that the jaws 84 are normally pulled backwardly and inwardly, and thus the spring 90 helps take up slack in the mechanism.
- the entire unit, including the body element 79 is raised upwardly from a position such as that shown in FIGS. 6 and 7 to a position such as that shown in FIG. 11, so that the spring 76 is compressed, and the bracket or bell crank 68 can pivot about the pivot pin 102.
- the toe of the ski boot When inserting the ski boot in the present invention, initially, the toe of the ski boot is placed in the toe clamp 34, and the heel is forced downwardly and this causes the heel to engage the jaws 84 to return the parts from the position such as that shown in FIG. 11 to a position such as that shown in FIGS. 6, 7 and 8, so that the ski boot will be properly clamped in position.
- the entire body element 79 and associated parts lift upwardly to the position shown in FIGS. 11, and the number 68 can pivot about the pin 102 against the tension of the spring 76, so that the heel can clear the mechanism including the jaws 84, and for a forward fall, the jaws 84 do not have to spread apart.
- one or both of the jaws 84 can pivot outwardly about the pivot pins 83 so that the ski boot will come free of the mechanism.
- the ski binding of the present invention provides maximum safety as well as maximum ski control and maximum convenience. Maximum safety is assured because the present invention eliminates the possibility of hang up between the toe of the boot and the ski. In addition, it changes the pivot point in releasing the skier from the heel to the front of the toe, to from the ball of the foot to the heel, that is it has a shorter lever, thereby decreasing the leverage of the twist against the leg. It decreases the friction under the foot from that required to move the toe across the ski while pivoting at the heel to the pivot under the ball of the foot to the mean distance to the outside of the ski, which is approximately 1 inch against approximately 1 foot or approximately a l2 to l improvement.
- the pivot point which locates the ski sideways, forward and backwards within 2 or 3 thousandths of an inch. It eliminates unwanted release from the chattering or hitting objects on the side of the boot such as salorn poles or ruts or mogul. It gives much improved edge control because the ski boot is securely fastened to the ski with 3 contact points along each edge. The boot is more securely fastened because the user can actually pry the sole over the pad at the ball of the foot giving tremendous security without causing the release. Further, the binding releases only in a twist at a predetermined pressure or in a straight forward fall, and does not release in unwanted directions.
- the present invention also provides maximum convenience,because it is a true step-in, needs no cocking, and has a convenient easy release at the toe without stooping or fumbling behind the user.
- the device is very convenient to mount with one template for boot, heel and toe pieces. Also there are no unsightly or hard to mount fixtures on the boot, and the device is light in weight and simple and easy to adjust and test.
- An important aspect or feature of the present invention is the pivot 52'under the ball of the foot, and this pivot does several things, mainly, it fastens the user on mechanically in a lateral position.
- the present invention helps absorb shock and chattering of sking as well as the eliminating of twisting action, and with the pres ent invention, the ski is actually manuevered by balancing the weight forward and backward and setting the edge.
- the boot is fastened to the ski in a very efficient manner.
- the toe piece essentially operates as a guide to guide the foot on the center of the pin. The boot is released in the event of a twisting action.
- the toe piece requires no adjusting, and has just sufficient spring action to hold the toe in position and guide the foot in place.
- the pin such as the pin 52 helps hold the ski in position both forward, backward, and laterally, and as the ski bends, the distance is shorter.
- the present invention provides improved safety features, as well as improved operation.
- the device is easy to install, and has elasticity, and the device does not release prematurely or accidcntly.
- the binding is easy to get into and out of, and the device will release at predetermined pressures.
- the heel mechanism can be adjusted forward and backwards.

The numeral 60 indicates a casing or housing, and the casing 60 includes a horizontally disposed first portion 61 that has a depending flange or lip 62 on its rear end and the lip 62 is provided with an opening; 63 through which extends a screw member or bolt 64, and this construction permits fine adjustments to be made to accommodate different sizes of ski boots and the like. The screw member 64 has a slotted head 65 to permit a tool such as a screw driver to be arranged in engagement therewith to effect the desired adjustment of the casing 60 and associated parts. The casing 60 further includes an upstanding second portion 66 as well as a horizontally disposed third portion 67.
The numeral 68 indicates an L-shaped bracket that includes a generally horizontal portion 69 as well as a vertical portion 70. A screw member or bolt 71 is vertically disposed, FIG. 7, and the screw member 71 has a head 72 on the upper end thereof, and the head 72 extends through an opening 73 in the top 67 of the casing 60. The screw member 71 is arranged in threaded engagement with a cross piece 80, and the cross piece is secured by welding to a head 74 of a bolt or pin 75, there being a coil spring 76 that is circumposed on the bolt or pin 75, FIGS. 6, 7 and 1].. One end of the coil spring 76 engages a retainer 77, and the retainer 77 bears against a surface 78 of a body element 79. The body element 79 is provided with upper and lower flanges 81 and 82, FIG. 6, and pivot pins 83 extend through the flanges 81 and 82 to provide a pivot mounting for the pair of heel latches or jaws 84. The jaws 84 are cut away or recessed as at 85, FIG. 12. In addition, portions of the jaws 84 are recessed or cut away so as to define shoulders 86 that are engaged by a shoulder 87 of a bushing 88. Numeral 89 indicates a screw member or bolt that extends through the bushing 88, and the screw member 89 has a coil spring 90 mounted thereon, FIG. 12, there being a square shaped nut or fastener 91 that threadedly engages the rear portion of the bolt or screw member 89. The nut 91 is snugly arranged or positioned in a hollow extension 92 that projects rearwardly from the body element 79, FIG. 7. As shown in FIG. 9, the casing 60 includes spaced parallel vertically disposed side walls or side portions 93 that are recessed or cut away as at 94, and the numeral 95 indicates a shaft or pin that has rollers 96 on the ends thereof, and the recesses 94 in the side walls 93 provide clearance for the rollers 96. The numeral 97 indicates links that have a rocking or pivotal connection as at 99 with the front end of the L-shaped bracket 88. The numeral 98 indicates pivot pins for the retainer 77, FIG. 11.
As shown in the drawings, FIGS. 9 and 10, dismetrically opposed ribs 100 are arranged on the outer sur faces of the side walls 93 for sliding engagement with groove 101 in the base plate 56, whereby when the screw member 64 is rotated or adjusted, the parts can be properly adjusted, so that they will remain in their proper aligned position.
From the foregoing, it will be seen that there has been provided a ski binding, and in use, with the parts arranged as shown in the drawings, a ski boot such as the ski boot 31 is adapted to be positioned so that its toe portion is clamped by the mechanism 34, while the heel portion of the ski boot is clamped or held in place by the heel mechanism 35. The sole 33 has a recess 53 in the lower portion thereof for receiving a pivot pin 52 that is mounted on the ski 32, and, if desired, a disk or the like can be arranged adjacent the pivot pin 52 to permit swivelling of the ski boot. The pair of jaws 40 clamp and hold the toe portion of the ski boot in place, and the jaws 40 are maintained in their proper position by means of a spring member 46. It will be noted that the toe clamp 34 has the release mechanism therein which consists of the opening 51 in the housing 36, whereby the tip of a ski pole can be conveniently inserted down through the opening 51 to engage the cam surfaces 50 so as to exert pressure on the jaws 40, in order to release the toe portion of the ski boot when desired or required. The jaws 40 are provided with the flanges 48 that are recessed as at 49, so that the jaws snugly and properly engage and secure the toe portion of the sole of the ski boot in its proper location.
The heel clamp 35 is provided with a pair of jaws or latches 84 that are pivotally connected in place on the pivot pins 83, and the jaws 84 are recessed or tapered as at 85 to properly engage the heel portion of the ski boot. A screw member 64 can be adjusted by arranging a screw driver or other tool in engagement with the head 65, whereby the screw member 64 can be rotated to shift or move the entire casing 60 and its associated parts in a forward or backward direction so that a firm adjustment is provided for permitting the device to accommodate or receive ski boots or different shapes or sizes.
With further reference to the toe clamp 34, the pair of jaws 40 are pivotally mounted on pins 45 and these jaws are arranged or biased into their proper position by means of a spring member 46.
As to the rear clamp 35, the bell crank 68 and the spring 76 exert a rearward force on the bell crank 68 about an axis extending through the pivot pin 102, FIGS. 6 and 11, and the bell crank or bracket 68 will selectively exert a downward force on the links 97. The spring member 76 can be adjusted by rotating the screw member 71, and this can be conveniently accomplished by gaining access to the slotted head 72, due to the provision of the opening 73.
The ski binding will not release during normal use of the skis, but in the event that the user falls forward, for example, then the upward force of the heel against the jaws 84 will cause the links 97 to push the bell crank 68 up against the tension of the spring 76, so that the body element 79 will rest on top of the housing or casing, as shown in FIG. 9. The recesses 94 in the sides of the casing receive the rollers 96 so that sufficient clearance is provided for the rollers to move therein, and thus the recesses 94 act as guide surfaces for the rollers. As soon as the parts reach a position such as that shown in FIG. 11, the ski boot will be safely released from the heel clamp so that the ski will not be locked onto the ski boot, whereby the users foot with the ski boot thereon will safely come loose from the ski, and thus the present invention serves as a safety release to prevent broken bones, such as a broken leg, and the like. Thus, the ski boot comes loose when sufficient pressure is applied to the mechanism.
In addition, the device has a cocking action and also includes the fine adjustment consisting of the member 64 that engages the lug 58. The spring serves to provide proper tension or pressure on the jaws 84 so that the jaws 84 are normally pulled backwardly and inwardly, and thus the spring 90 helps take up slack in the mechanism.
In the event of a fall, the entire unit, including the body element 79 is raised upwardly from a position such as that shown in FIGS. 6 and 7 to a position such as that shown in FIG. 11, so that the spring 76 is compressed, and the bracket or bell crank 68 can pivot about the pivot pin 102.
When inserting the ski boot in the present invention, initially, the toe of the ski boot is placed in the toe clamp 34, and the heel is forced downwardly and this causes the heel to engage the jaws 84 to return the parts from the position such as that shown in FIG. 11 to a position such as that shown in FIGS. 6, 7 and 8, so that the ski boot will be properly clamped in position.
As previously stated, in the event of a forward fall, the entire body element 79 and associated parts lift upwardly to the position shown in FIGS. 11, and the number 68 can pivot about the pin 102 against the tension of the spring 76, so that the heel can clear the mechanism including the jaws 84, and for a forward fall, the jaws 84 do not have to spread apart.
In the event that the user falls sideways, one or both of the jaws 84 can pivot outwardly about the pivot pins 83 so that the ski boot will come free of the mechanism.
The ski binding of the present invention provides maximum safety as well as maximum ski control and maximum convenience. Maximum safety is assured because the present invention eliminates the possibility of hang up between the toe of the boot and the ski. In addition, it changes the pivot point in releasing the skier from the heel to the front of the toe, to from the ball of the foot to the heel, that is it has a shorter lever, thereby decreasing the leverage of the twist against the leg. It decreases the friction under the foot from that required to move the toe across the ski while pivoting at the heel to the pivot under the ball of the foot to the mean distance to the outside of the ski, which is approximately 1 inch against approximately 1 foot or approximately a l2 to l improvement. Because this is where most breaks are caused, it is estimated that an improvement in this of 2 to 1 would prevent approximately 90 percent of the breaks, and the improvement of l2 to 1 would eliminate all breaks cause d by this. friction. Further, the pivot point gives a direct mechanical tie between the boot and the ski and absorbs the shock and chatter of skiing and eliminates the necessity of using the release mechanism to absorb the same. It eliminates unwanted release and relieves the fear of breaking the leg by twisting.
As to maximum ski control, this is accomplished due to the provision of the pivot point which locates the ski sideways, forward and backwards within 2 or 3 thousandths of an inch. It eliminates unwanted release from the chattering or hitting objects on the side of the boot such as salorn poles or ruts or mogul. It gives much improved edge control because the ski boot is securely fastened to the ski with 3 contact points along each edge. The boot is more securely fastened because the user can actually pry the sole over the pad at the ball of the foot giving tremendous security without causing the release. Further, the binding releases only in a twist at a predetermined pressure or in a straight forward fall, and does not release in unwanted directions.
The present invention also provides maximum convenience,because it is a true step-in, needs no cocking, and has a convenient easy release at the toe without stooping or fumbling behind the user.
The device is very convenient to mount with one template for boot, heel and toe pieces. Also there are no unsightly or hard to mount fixtures on the boot, and the device is light in weight and simple and easy to adjust and test.
An important aspect or feature of the present invention is the pivot 52'under the ball of the foot, and this pivot does several things, mainly, it fastens the user on mechanically in a lateral position. The present invention helps absorb shock and chattering of sking as well as the eliminating of twisting action, and with the pres ent invention, the ski is actually manuevered by balancing the weight forward and backward and setting the edge. The boot is fastened to the ski in a very efficient manner. Also, there is provided a unique means for releasing the skier from the ski by inserting a ski pole through the opening 51. The toe piece essentially operates as a guide to guide the foot on the center of the pin. The boot is released in the event of a twisting action. The toe piece requires no adjusting, and has just sufficient spring action to hold the toe in position and guide the foot in place. The pin, such as the pin 52 helps hold the ski in position both forward, backward, and laterally, and as the ski bends, the distance is shorter.
The present invention provides improved safety features, as well as improved operation. The device is easy to install, and has elasticity, and the device does not release prematurely or accidcntly. The binding is easy to get into and out of, and the device will release at predetermined pressures. The heel mechanism can be adjusted forward and backwards.
It will not be clear that there is provided a device which accomplishes the objectives heretofore set forth. While the invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof as described and illustrated herein is not to be considered in a limited sense as there may be other forms or modifications of the invention which should also be construed to come within the scope of the appended claims.
