Mitchell Att0meyLeo Gregory [5 7] ABSTRACT A stop structure for skis consisting of a plate member secured to a ski adjacent the rear of a ski boot, a spring tensioned arm journaled in said plate member, said arm being adapted to swing forwardly outwardly of the ski in the direction of said boot and said arm in operative cocked position bearing against the upper heel portion of said ski boot.

4 Claims, 4 Drawing Figures SKI STOPPING STRUCTURE BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to a ski stopping structure to stop the travel of a loose ski.

It is desirable to have a stop structure for a ski which is free in operation from any engagement with the bindings securing the ski boot thereon or with the sole portion thereof.

The nearest related structure appears to be disclosed in U. S. Letters Pat. No. 3,195,9ll dated July 20, 1965, to M. H. Cubberley in which the ski arresting device is mounted in a position forwardly of the toe binding for a ski boot and comprises a bracket plate in an oblique angular relationship to the longitudinal axis of the ski and having an arm parallel to the edge of the ski to underlie the toe portion of the ski boot. There exists a possibility of entanglement between the lever arm comprising the stopping member of the device and the closely adjacent binding structure and such entanglement has been known to occur in actual practice.

It is an object of this invention, therefore, to provide a ski stopping structure which in operative position is free from the possibility of entanglement with a ski binding.

It is another object of this invention to provide a ski stopping structure which is held in a cocked operative position by bearing against a portion of a ski boot remote from any portion of the boot sole.

It is also an object of this invention wherein the size of the ski stopping member is free from any restrictions which might be dictated by the design of the structure of the ski boot bindings.

It is also an object of this invention to provide a ski stopping structure which is situated to be free from being frozen into an inoperative position such as by underlying a sole portion of a ski boot.

More generally it is an object of this invention to provide a ski stopping structure which includes a bracket plate disposed substantially at right angles to the longitudinal axis of the ski, an arm member having a portion journaled in said bracket plate, a helical torsion spring disposed about said journaled portion of said arm, said arm being curved upwardly inboard of said ski having an upper terminal portion which bears against the upper portion of a ski boot to be cocked in operating position and said arm upon removal of said boot from said ski being disposed to swing forwardly to a ski stopping operative positive outboard of said ski.

These and other objects and advantages of the invention will be set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:

FIG. 1 is a broken view in top plan showing the structure herein in operating position;

FIG. 2 is a view similar to FIG. I in side elevation and FIG. 3 is a view thereof in end elevation; and

FIG. 4 is a view similar to FIG. 3 showing a modification of the structure herein.

DESCRIPTION OF A PREFERRED EMBODIMENT With reference to FIGS. I-3, a broken portion of a ski is shown comprising an upper surface portion 11 and a side edge portion 12 which will be referred to as the outer edge of said ski. Disposed on said ski is a ski boot 15 of a conventional design and securing the same in position is a conventional type of ski binding 17. Ref erence is made to a ski binding per se of which there are a variety of designs as to structure and neither the particular design of the ski boot nor of the ski bindings form a part of the structure comprising the invention herein. A type of binding is indicated which has its rear structure closely adjacent the ski boot and this is on the order ofa Besser or Gertsch binding which bindings are known in the art. For purpose of reference the upper rear portion 10 of said ski boot is sometimes referred to as the upper heel portion.

The structure comprising the invention herein is indicated generally by the reference numeral 25. Said structure comprises a bracket plate member 27 extending crosswise of the ski substantially at right angles to the longitudinal axis thereof and is suitably secured thereto as by screws 28. Said plate is disposed closely adjacent the rear of the ski boot and of the portion of the binding securing the heel portion of said boot.

In the embodiment of the bracket plate member here shown, a plate portion 29 integral therewith is angled upwardly therefrom in the direction of the outer edge 12 of said ski. Said plate portion will be angled upwardly in the direction of the right hand side of the right ski and of the left hand side of the left ski. Said angled portion may be somewhat outboard of the ski but not more so preferably than the width of the ski boot and preferably it may be angled upwardly on the order of 3045 to the horizontal.

Said angled portion 29 of said bracket plate member has a pair of upstanding spaced

bearing plates

32 and 33 extending inboard of the ski substantially at right angles to said angled plate portion and said bearing plates have aligned bores 32a and 33a therethrough forming bearings. Said angled portion has a finger like outboard projection 34 forming a stop member as will be further described.

A braking arm 35 is provided having a lower portion 36 thereof journaled in said bearing plates and extending through said plate 32 and having its lower free end flanged as at 37 forming a stop to retain said journaled portion in said bearing plates. A helical torsion spring 40 is disposed about the journaled portion of said arm between said bearing plate members having one end 42 thereof engaging the edge portion of the bearing plate 30 and having its other end 43 secured about a pin 44 disposed through said arm.

Said braking arm 35 has an upper portion 38 curved inboard of the ski from said journaled portion 36 to have its upper terminal portion 39 positioned to be centered upon the upper heel portion 20 of said ski boot. Said terminal portion may be variously formed and it is here shown as being semi-spherical in form having its convex surface portion 39a bearing against and engaging said boot and its concave surface portion 39b will form a scoop in braking the loose ski to a stop when the arm is in operating braking position.

It will be noted that said torsion spring is secured and disposed to have said arm 35 cocked under spring tension when moved upwardly rearwardly to the rear of the ski boot to bear thereagainst and said arm will be under sufficient operating tension that when said ski boot is broken free from the bindings, said arm will swing forwardly and downwardly outboard of the ski to dig into the snow to stop the sliding movement of the ski. Reference is had to the illustration shown in FIG. 3 and particularly to the dotted portion thereof.

MODIFICATION A modification of the structure above described is provided in which like reference numerals will indicate like elements of structure.

A bearing bracket member indicated generally by the reference numeral 50 comprises a base plate portion 51 extending crosswise of said ski adjacent the rear of said boot l5 and of the bindings 18 thereof and is suitably secured as by screws 52. Said bracket is formed having an upright wall 53 having as an upward inward or inboard extension thereof a plate portion 54 angled inwardly therefrom and having secured therein and disposed therethrough a bearing sleeve 56 which preferably will be held by said plate portion 54 as by being welded thereto to have its axis disposed on the order of 30-45 with respect to the horizontal and upwardly in the direction of the outer edge of the ski.

A braking arm 60 is provided having a lower stem portion 62 having its end portion journaled into said sleeve 56 and having its lower free end 63 extending therethrough and being flanged to retain said stern portion within said sleeve.

The upper portion 65 of said arm is curved inboard of said ski and is here shown being curved through a somewhat wider arc than was the case with the arm 38 first above described and said arm is shown having a semi-spherical terminal portion 67 having its convex side engaging the upper end portion of said ski boot.

Disposed about said stem portion 62 above said sleeve 56 is a helical torsion spring 70 having its lower end portion 71 disposed through an accommodating aperture in said plate portion 54 and having its upper end portion 73 secured about a pin 75 disposed through and secured in said arm portion 62.

Extending from said arm portion 62 adjacent the upper portion of said sleeve 56 is a stop pin 77 which engages a projection 78 extending outwardly somwhat outboard of said ski as being struck from said plate member portion 53 which projection upon engagement by said pin 77 holds said arm 60 in operating braking position as indicated in dotted line in FIG. 4.

It is believed clear from the description that the modifred form of the invention herein like the preferred embodiment permits the braking arm to swing forwardly and downwardly outboard of the ski and in advance of the bindings thereon to dig into the snow to stop sliding ski movement. Said braking arm is free from any contact with the sole of the ski boot and avoids being frozen into such position. Further the design of the braking arm is free from any restriction which might otherwise be imposed by the design of the ski bindings. It will of course be understood that various changes may be made in form, details, arrangement and proportions of the parts without departing from the scope of the invention herein which, generally stated, consists in an apparatus capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.
