This invention consists of a standard ski on which is mounted, by means of two metal tubes, a body embodying an elongated frame that is covered with canvas. Handle bars are mounted on the aforesaid ski in front of the body on which a rider lies in a prone position when riding the sled. Two spring-loaded outrigger runners are mounted for stability, one being mounted on each side of the sled. The aforesaid ski and the two outrigger runners are removably secured to the structure of the sled so that the sled may be disassembled in order to take up a minimum amount of space when it is being transported.

SHEET 2 DF 2 IN VEN TOR JACOB KRIPP ELZ ou'rrucor-:rt sLsn This invention relates to sleds; more particularly. to a sled having a new and novel arrangement of runners which in this invention consist of a centrally located runner that is a ski and two spring-loaded outrigger runners that give lateral stability to the sled, as will hereinafter be described.

It is the principal object of this invention to provide an outrigger sled that will travel just as well on snow or ice with maximum maneuverabilty and safety.

Another object of this invention is to provide an outrigger slid that embodies a canvas covered body supporting frame that increases the comfort of the ride.

Another object of this invention is to provide an outrigger sled of the character herein described that is both light in weight and sturdy in construction.

Still another object of this invention is to provide an outrigger sled that can be disassembled, being made into a compact package for transportation to its place of use, then reassembled with ordinary household tools in a minumum of time by even the most inexperienced person.

These and other objects and advantages of this invention will no doubt appear as the reading of this specification and its appended claims proceeds along with an examination of the accompanying drawings.

In the drawings:

FIG. l is a pictorial view of this invention in its entirety.

FIG. 2 is a front view of this invention.

F IG. 3 is a rear view of this invention.

FIG. 4 is a bottom view of this invention with a portion of the center runner removed for reasons of clarity.

FIG. 5 is a side view of this invention.

FIG. 6 is a pictorial exploded view of that portion of this invention that is enclosed within the arrowed circle in FIG. 5 and indicated by the number 6.

FIG. 7 is a pictorial view of that portion of this invention indicated by the arrowed line and number 7 in FIG. I.

In the several views of the accompanying drawings like parts of this invention are indicated by like reference numbers, the reference number l indicating this invention in its entirely.

Directing ones attention to FIG. I of the accompanying drawings it will be seen that this outrigger sled l0 consists of a standard ski ll which is the center runner of the sled and also provides a support for the handle bars l2 and the body I3 of the sled. The aforesaid handle bars I2 consist of two pieces of metal tubing, that are L-shaped when viewed from the side as illustrated in FIG. of the drawings, and also has the configu ration of an inverted capital letter L when viewed from the front as in FIG. 2 of the drawings. Each aforesaid handle bar l2, which is secured by rivets or screws to the aforesaid ski II, is provided with hand grips I4. The body of the aforesaid sled l0 embodies an elongated frame I5 that is likewise made of metal tubing which has its front end supported by a centrally located (in the lateral plane) piece of metal tubing 16 that has a vertically disposed member and a horizontally disposed member 17 that passes through the metal block I8. The metal block 18 is provided with an inverted U-shaped recess 19 in the bottom thereof that is at right angle to the aforesaid horizontally disposed member I7. The aforesaid block I8 is adapted to fit on the vertically disposed lug 20 that is centrally secured to, or made integrally with the square base 2l, which is secured to the already mentioned ski ll of this invention. A pin or bolt, that is not illustrated in any of the views of the accompanying drawings, passes through openings in both the aforesaid block 18 and the lug 20, thus locking these two parts of the invention together. The aforesaid block I8 and the lug 20 are best illustrated in FIG. 6 of the accompanying drawings.

Looking now at both FIGS. I, 3, and 5 of the drawings it will be seen that the rear end ofthe aforesaid horizontally disposed member I7 also passes through a block 22 that is identical to the already described block IB and its supporting lug and base that are secured to the rear portion of the ski l I. The apex 23 of that portion ofthe metal tube 24 that forms the framework of the body portion of this invention is suitably secured to the rearmost end of the often-mentioned horizontally disposed member I7, thus supporting the rear end ofthe aforesaid body of the sled.

Directing ones attention now to FIG. 4 of the accompanying drawings it will be seen that the canvas cover 25 of the aforesaid body that tits over the framework of the body of the sled is secured onto the framework by means of a cord 26 that is threaded back and forth in a V-shaped pattern through grommets in the edge of the canvas cover 2S. Still looking at FIG. 4 of the drawings as well as at FIGS. 2 and S, it will be seen that a lug 27 is secured to each underside of the frame of the aforesaid body of the sled in order to provide support for the spring-loaded outrigger runners 28 of which one runner is secured outward on each side of the aforesaid sled by means of an inverted L-shaped tube 29 that has its outer end terminating in securement to the fitting 30 which is fastened on top of the outrigger runner 28. A lever 3l has one end secured to the aforesaid inverted L-shaped tube 29 and the other end secured to the upper end of a coil spring 32 that has its lower end secured to the aforesaid ski II, as is clearly shown in FIGS. l and 2 of the accompanying drawings. This novel mounting of the aforesaid outrigger runners permits the runners to automatically ride over any rough ice or snow without the use of manual controls by the rider on the sled. There is of course one of the aforesaid coil springs for each outrigger runner.

It is to be realized by those experienced in the art of riding sleds that the rider will lay prone on the body of the sled whose canvas will provide a certain amount of give and thus insure the n'der of a comfortable ride even over rough ice or snow. The two aforesaid outrigger runners 28 are basically small skis whose purpose is to prevent the sled from overturning.

What I now claim as new is:

I. An outrigger sled; comprising a standard ski, a body on which a person can lie prone when riding the said sled, said body comprising an elongated frame having a rounded front end; a sheet of canvas covering said frame, a plurality of spaced grommets located in the longitudinal edge of said sheet of canvas, a cord threaded back and forth through said grommets to hold the canvas in place on said frame; a metal tube that is substantially V-shaped the ends of said metal tube secured to the sides of said frame near the rear thereof, a second metal tube that is L-shaped when viewed from the side, the upper end of the vertical portion of said second tube secured to the underside of the front end of said elongated frame, the rear end of the horizontally disposed portion of said second metal tube being secured to the apex of said metal tube; means removably securing said horizontal portion to the standard ski; a handle bar secured to the sled at the front of said frame; an outrigger runner secured to said sled at each side of the body and means for spring loading the outrigger runners.
