Description

mvew foe N inO CANTE LLI March 12, 1963 A T TO/PNFY United States Patent Ofifice Ihe present invention relates to a new device or implement for winter sports.

Actually in winter sports there are used sledges, skis and their derivatives.

The conventional sledges are made up of two fixed runners or sk' and a seat or other similar resting piece on skis are strongly fastened to the feet.

The object of the invention is to provide a new sport device or implement of the kind hereinb-efore described regard to these latter; and control means adapted to aotuate on the skis so as to brake both the skis simultaneously or singly.

The present invention will be better illustrated through the detailed disclosure hereinafter set forth concerning a particular embodiment of the present invention, which is to be understood as being given as an example and not to be limited to it, reference being made to the annexed drawing, wherein:

FIG. 1 shows a side elevation view of the device or implement -for winter sports according to the present invention;

FIG. 2 is a plan view of the device or implement of F1 1;

FIG/3 shows in enlarged scale a portion of the device or implement of 'FIGS. 1 and 2; and

I IG. 4 shows in enlarged scale another portion of the 1 of the conventional type.

tending upwardly from the ski, and a rear one 4 being formed with a longer vertlcally extending leg. Skis 1 are connected with each other by means of a frame assembly made up of two triangle shaped frames 5 and 6, the front one 5 being sloped rearwardly, as clearly shown in FIG. 1, tied with each other by means of two side braces or struts 7 which serve as pivots for the attachment angle plates of the skis, and a top arm 8 on which the seat 9 is pivoted for angular movement about a fore and aft axis It is noted that the con- The side rear edges of seat 9 are connected each to the 3,081,107 Patented Mar. 12, 1963 top end of rear leg of attachment 4 of corresponding ski by means of a flexible wire 10 guided by a pulley 11 Adjacent the inside edge of each ski there is a runner 14 which is fixed on the lower transverse bars of the frame pivotally mounted on the legs of the attachment rear angle pieces 4, and a central body or tube, so that this bar 13 can be easily taken apart.

The skis 1 are readily dismantled; therefore the implement or device of the present invention may be packed is to say he will exert downward force on the grips 19 of the rods 18 controlling said shoes 16, so that the runners 14 will not be braked and the contrivance will run downhill at the utmost possible speed.

If the sledger wishes toslow down or to stop he will then raise the grips 19 of said control rods which will thus braked by the snow cushion which will be so formed. In the case a slowing down only is wished then shoe 16 will be brought near the runner and lowered somewhat, whereas when stopping is wished then the shoes will be i.e. they keep up the required inclination of the skis to the snow.

and changes may be made on the contrivance according to practical needs without however departing from the scope and greater aim of the present invention.

What I claim is:

1. A ski sled comprising a frame assembly, first and second skis, means pivoting said skis to said frame assembly for pivotal movement about respective parallel first and second axes each parallel with the longitudinal axis of, and closely above a respective one of said skis, a seat mounted to said frame assembly for pivotal move ment about a third axis, between, above and parallel with, said first and second axes, means connecting said seat and skis to effect equal pivotal movement thereof by and in response to pivotal movement of said seat, and in the same direction of rotation, first and second elongated runners each carried by said frame assembly closely adjacent and parallel with a respective ski and above the lower surface thereof, first and second angle plates each mounted on said frame assembly immediately above the rearward end of a respective runner, for pivoting about axes transverse of said skis, pivotal movement of each said angle plate operating to depress an end thereof across the rearward end of its runner to a position below the lower surface of the corresponding ski, to effect braking, and a pair of brake levers, each connected with a respective one of said angle plates and positioned to be grasped at one end by an operator on said seat.

2. A ski sled comprising a pair of skis, a frame assembly, first means connecting said skis to said frame assembly in parallelism for rotation about longitudinal axes each close to and above a respective ski, a seat carried by said frame assembly for pivotal movement about an axis between, above and parallel with said longitudinal axes, second means connecting said seat and skis for pivoting in synchronism about their respective axes, a pair of runners carried by said frame assembly, each adjacent and parallel with a respective ski, and above the level thereof, a pair of brake shoes each pivoted on a transverse axis above and at the rearward end of a respective runner, a pair of brake levers each connected with a respective shoe and operable by an operator in said seat to lower the shoe about the rearward end of the corresponding runner, into engagement with snow compacted thereby.

3. A ski sled as in claim 2, said second means comprising a pair of arms each fixed to and rising from a respective one of said skis, a pair of pulleys journaled on said frame assembly, and a pair of cables, each fixed at its one end to said seat, passing over and about a respective pulley, and fixed at its other end to the distal end of a respective arm.

4. A ski sled as in claim 2, each said brake shoe comprising a pair of flat plates, connected substantially at right angles along contiguous edges, each said hoe being pivoted to said frame assembly on a transverse axis along an edge of one of said plates offset from and parallel with said contiguous edges, each said transverse axis being immediately above the rearward end of a respective runner, pivoting of each shoe causing progressive lowering of its free edge into braking engagement with snow compacted by its corresponding runners and eventually pressing the rearward end of the runner into the snow.
