Primary ExaminerBenjamin Hersh Assistant Examiner-Milton L. Smith Attorney-Craig, Antonelli, Stewart & Hill ABSTRACT: A safety ski binding in which the boot is secured to the ski by means of a plate fastened to the boot sole intermediate its heel and toe.
SAFETY SKI BINDING The present invention relates to a safety ski binding.
Safe ski bindings of the most varied type have found wide applications in recent years to protect skiers against injury in case of falls. For the most part, the prior art safety ski bindings utilize a release mechanism to release the binding in case of excessive twisting force of the leg and a further release mechanism to release the ski binding in case of forward falls. Apart from the fact that generally two separate release mechanisms are used, increasing the number of parts, the time for installation and therewith the cost of the safety ski binding. the prior art safety ski bindings also entail the considerable disadvantage that they require special skills for proper adjustment, are highly sensitive and require readjustrnents in case of a change in the size of the ski boot of the person using the skis.
It is an object of the present invention to provide a safety ski binding which avoids the aforementioned shortcomings and drawbacks encountered in the prior art.
A further object of the present invention resides in a safety ski binding which is simple in construction, involves relatively few parts and can be used with any size ski boot.
Still a further object of the present invention resides in a safety ski binding which is relatively inexpensive, easy to install and particularly simple in its adjustment while at the same time enhancing ski-edge control.
The underlying problems are solved by the present invention in that the safety binding consists of a ski plate secured to the ski, on which are pivotally mounted along the longitudinal sides thereof, two levers provided at-the forward ends with retaining pawls and interconnected at the rear end by a toggle lever assembly, preferably an adjustable toggle lever assembly, to provide the necessary spring loading. Additionally, forwardly of the pawls are mounted on each side of the ski plate a roller which is intended to guide the lateral projections of a sole plate mounted on the sole of the ski boot intermediate its toe and heel in such a manner that the pawls normally hold the projections and therewith the ski boot in place until a predetermined force in excess of the adjusted force occurs, thereby releasing the ski binding.
These and further objects, features, and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawing which shows, for purposes of illustration only. one embodiment in accordance with the present invention'and wherein:
FIG. I is a side elevational view of the safety ski binding in accordance with the present invention in the released condition;
FIG. 2 is a side elevational view, similar to FIG. I, of the safety ski binding in accordance with the present invention with the ski boot held in place by the engaged binding;
FIG. 3 is a side elevational view, similar to FIGS. I and 2, illustrating the position of the parts after release of the ski boot;
FIG. 4 is an end elevational view on the safety ski binding in accordance with the present invention;
FIG. 5 is a rear elevational view on the toggle-lever arrangement of the safety ski binding in accordance with the present invention; 1
FIG. 6 is a top plan view on the safety ski binding in accordance with the present invention;
FIG. 7 is a plan view on the ski boot sole plate of the safety ski binding in accordance with the present invention;
FIG. 8 is a side elevational view of the sole plate of FIG. 8;
, and
FIG. 9 is a transverse elevational view of the sole plate of FIG. 8.
Referring now to the drawing wherein like reference numerals are used throughout the various views to designate like parts, the ski which may be of any conventional construction is generally designated by reference numeral I0,on which is mounted the ski plate generallydesignated by reference numcral which is fastened conventionally, for example, by screws 21 to the ski. The plate 20, for ease of manufacture, is a solid plate having a substantially rectangular portion 20a and a tapering portion 20!: (FIG. 6) extending rearwardly from the rectangular portion 20a. One lever each, generally designated by reference numeral 30 is pivotally mounted by conventional means, indicated by reference numeral 31 on the side of the plate 20. Each lever 30 includes a pawl generally designated by reference numeral 32 at its forward end which is formed by an upwardly extending portion 32a and an approximately horizontal forwardly extending portion 32!) whereby the forward edge 32c (FIG. I) may be suitably shaped, for example, beveled off to facilitate the release of the boot and to facilitate engagement of the boot plate when inserting the boot in the binding.
Along the rear end, each lever is provided with an upwardly bent portion 33, the upwardly extending ends 33 of the two levers being interconnected by a yoke member 34, pivotally connected with each upwardly extending portion 33 and provided with an enlarged portion 35 in its center which is suitably bored and tapped to receive the threaded portion 41 of the adjusting member generally designated by reference numcral 40. At its upper end, the adjusting member is provided with an actuating member 42 of ball-shaped configuration, though any other shape may be used. At its opposite end, the adjusting member 40 is provided with an engaging member 43 made of any suitable material, such as nylon, steel or the like, which is appropriately secured to the lower end of the adjusting member 40. The engaging member 43 is of curved configuration, for example, of approximately hemispherical shape to facilitate spring-loading of the levers 30 during tightening of the ski binding and has a flat area on the bottom to ensure stability of the toggle in an upright position when the boot is clamped in place. Additionally, any conventional means, such as, a lock nut 44, may be provided to hold the adjusting and actuating member 40 in its adjusted position. Elements 41, 42, 43 and 34 thus form a toggle lever assembly.
A boot plate generally designated by reference numeral 50 is suitably secured to the sole of the ski boot intermediate the toe and heel andmore particularly within the area of the instep, for example, by means of screws (not shown) shown) which extend through countersunk hole 51 provided for that purpose. In lieu of a mounting by means of screws, any other conventional means may be used, such as bonding by means of an epoxy resin which may also be used in addition to the screws. The plate 50 has a generally rectangular shape with its four corners 52 beveled off. Additionally, the plate 50 is also provided with lateral projections projecting laterally beyond the contour of the boot. More particularly, the dimension (1 of the plate 52 corresponds to the dimension a of the ski plate 20 whereby the dimension u should not exceed the dimension 0' and preferably is slightly smaller. On the other hand, the dimension h i.e., the length of a projection 53, is such that it extends into the path of the lever 30 and is substantially of the same length as the thickness of each lever.
As shown particularly in FIGS. 7, 8 and 9, each projection 53 is also provided with inclined surface 54 whose function will be explained more fully hereinafter. The angle a of the inclined surface with the horizontal is about 30 to 50.
A roller generally designated by reference numeral 60 is mounted conventionally on each side of the plate 50 at a point forwardly of the pawl 32. More particularly, the roller60 should be spaced from the forward surface of portion 32a of the pawl to such an extent that it will just accommodate the projection 53.
OPERATIGN The safety release binding of the present invention func- To mount a boot, provided with-a sole plate 50, on the, ski, the boot is inserted from in front by sliding the boot backwardly until the lateral projections 53 engage behind the rollers 60 with the ramp surfaces 54 in engagement with the roller 60. Thereafter, the actuating member 40 is pivoted counterclockwise through about 90 as viewed in FIGS. 1 and 2, whereby the engaging member 43 engages with the surface of the plate 20, thereby raising the rear portions 33 of the levers by pivoting the same about the pivot pins 31 so that the forward ends including the pawls are rotated counter clockwise and the forwardly extending portion 32h of the pawl engages the top of the lateral projections 53. The levers and pawls 30, 32 which are of steel, hardened and tempered after machining, act as springs, spring-loaded by the counterclockwise pivotal movement of the actuating member 40. As a result thereof, each lever 36 functions as a second-class lever, pivoted approximately in the center, with one end bearing on the boot plate 50, and the other end forced upward by means of the toggle lever 40 in order to exert the desired pressure on the boot plate to hold the same by a clamping action. The spring load can be adjusted by mere rotation of the toggle member 40, thereby raising and lowering the position of the engaging member 43. it is normally so adjusted that the boot is held in position during normal forces but is released when the forces at the boot, either twisting forces or forwardly directed forces exceed a predetermined value, determined by the adjustment of the member 40. Once the force at the boot exceeds the predetermined force, the boot is able to slide out over the roller 60, the pawl 32 snaps downward below the level of the ski plate top (FIG. 3) to thereby permit the boot to slide away from the ski without any obstruction on the part of the lever 30 or its pawl 32.
Thus, the pawls 32 are normally spring-loaded so as to maintain a rigid connection between the boot and the ski until a twisting force, nearly great enough to injure the skier's leg is encountered. When this force is reached, the spring-loading force on at least one of the pawls is exceeded, causing the pawl to lift and release the boot plate. For example, if the twisting force at the boot is clockwise, as viewed in plan view on the ski, the left pawl 32 will release, permitting the boot plate to twist out of its restraint by the pawls. If the twisting force is counterclockwise, the right pawl 32 will release, permitting disengagement of the plate 50 from the ski.
I [n the event the skier encounters an obstruction which stops one or both of the skis suddenly, the strong forward force on the boot plate will cause the pawls 32 to lift and to permit the boot plate 50 to slide forward out of engagement with the ski.
The rollers 60 rotatably connected to the sides of the ski plate 20, bear against the forward, sloping edges 54 of the projections 53, thereby formingan abutment means restraining forward motion of the boot plate when clamped down or held down by the clamping means constituted by the pawl 32. This arrangement causes the boot plate projections 53 to move, in effect, up an inclined plane when releasing from the ski. Consequently, the release force in the ski binding of the present invention can be adjusted to a reliable, predictable value.
The roller pivot pins, the boot plate projections, the pawlbearing surfaces and pivot pins should be suitably lubricated with a grease or with a solidstate lubricant such as molybdenum disulfide in order to reduce friction to a minimum and insure that the boot release force is of consistent magnitude.
It is also highlydcsirable as in other conventional release bindings to assure low friction at the points of contact between the boot sole and the ski plate by the use of metal or plastic plates attached to the sole at the toe end and at the heel. The
toe plate is particularly important in assuring a reliable release. For the same purpose, the plate may be extended forwardly or, in order to save weight, a separate section may be provided forwardly of the normal position of the sole plate 50 within the area of the toe portion of the bootso as to provide a level support for the boot. lf so desired, the toggle lever structure may also be spring-loaded to preventv chatter in the released condition and may be provided with means to permit conventional anchoring of a strap to hold the ski in case of binding release.
The present invention provides several advantages over the priorart bindings.
l. The firm spring-pressure clamping the edges of the boot to the edges of the ski assures enhanced ski-edge control, permitting more precise, accurately controlled turns.
2. The installation of the binding is very simple, and unlike those of conventional bindings with separate heel and toe units, can be installed in a relatively short time with little skill. Additionally, the safety binding of the present invention eliminates the need of a careful, skilled adjustment, necessary with the prior art bindings to insure proper operation of the safety release feature thereof. I
3. The safety binding of the present invention excels by simplicity in that it has fewer and more simple parts than any safety bindings used heretofore, especially those utilizing separate heel and toe units. Every boot, provided with a plate 50 will fit every ski with no adjustment required, a feature particularly important to rental applications.
4. The solid metal boot plate 50 has a manufactured-in" fit relative to the ski plate pawl-roller assembly which is permanent and completely firm with zero clearance since the lever 30 and roller 60 are pivotally mounted to the plate 20 at the plant in proper relation to each other,
While l have shown and described only one embodiment in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as known to a person skilled in the art, for example, instead of the toggle lever assembly, a conventional spring means may be provided to spring-load the levers; and I therefore do not wish to be limited to these details but intend to cover all such changes and modifications as are within the scope of those skilled in the art.
