Song [5 7] ABSTRACT A ski device is provided which is adapted to be detachably secured as a front guide runner to a handled shovel or scoop to utilize the scoop part of the shovel as a slide seat and the handle part as a forwardly up wardly extending hand grip. The device has a relatively narrow front runner part provided with backwardly extending arm means that is flexibly adjustable and adapted at its upper and back end to be secured on the handle of the shovel. The runner part also carries at its forward end a cross-extending footreceiving rung or abutment and a mounting and positioning part therefor which are adapted to position the shoes or feet of a rider for guiding the ski. The device, itself, is detachably mounted in order that the shovel may be put to its conventional usage.
19 Claims, 7 Drawing Figures PATENTED JUL 2 9 I975 1/ IIIIIIIIII/II BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an improved form of ski or sled device which utilizes a shovel to provide a unique operation assembly. A phase of the invention deals with a detachable runner and guide device for utilization in a cooperative relation with a shovel to provide an effective sled or ski unit.
2. Description of the Prior Art Heretofore, there have been various ski devices including devices which utilize a runner and a seat that is carried by a post in an upper position thereon. However, such a device is relatively unstable and difficult to control and in high speed operation is very dangerous. The present invention deals with devising an improved device that will be highly stable, comfortable for the rider and, at the same time, capable of accurate guide control.
SUMMARY OF THE INVENTION This invention deals with a ski device which will utilize adaptable parts of a shovel, such as of a shorthandled, scooplike shovel that may be of a coal or grain shovel configuration, so as to provide an improved body-supporting, slidable, positioning part of a ski assembly. The ski device, itself, will serve as a forward, feet-receiving, guiding, advanced runner that is adjustably and removably secured to the handle of the shovel in such a manner as to give the rider a comfortable, sta ble and secure position when utilizing the assembly and, further, in such a manner as to utilize the scoop portion as a back runner part of the assembly.
It has been an object of the invention to provide a new and improved form of ski or sled device and assembly.
Another object has been to devise a ski assembly that will make use of a shovel to provide a relatively high speed, stable, comfortable ride in a positively guidable sled or ski assembly.
These and other objects will appear to those skilled in the art from the illustrated embodiment.

DESCRIPTION OF THE PREFERRED EMBODIMENT With reference particularly to FIGS. 1, 2 and 3 of the drawings, A shows a typical shovel to which sled or ski device B may be applied to form an improved operating unit or assembly. As shown in FIG. 2, when the assembly is to be used, a rider C may sit onscoop part 10 of the shovel A with his legs extending on opposite sides of shovel handle or stem 11, and with his feet resting upon the device B to provide a comfortable riding position and one at which the assembly may be guided principally by the feet of the rider. If desired. the guiding may be supplemented by utilizing the gripping position of the hands of the rider C about the handle 11. It is immaterial whether or not the shovel A has a straight cylindrical end or a handgrip end part 12.
In employing the invention, it is preferable to provide a shovel whosescoop part 10 is of relatively planar or flat configuration having slightly up-turned side edges and a relatively smooth underside such that it will freely slide along snow or ice. In FIG. 3, downwardly offset or outwardly convex reinforcing ribbing is shown along the bottom surface of the shovel scoop part orbody 10 that, in the present utilization, serves to pro: vide a pair of speed-enhancing runner portions or ribs 10a. Thescoop part 10 is shown secured in the usual manner by a clamping flange portion 10b to the lower end of the handle or handle stem 11 in such a manner as to form a secure, unitary structure. Thescoop body 10 may be of any suitable material, such as ofsteel, reinforced plastic, glass fiber or aluminum construction, but is preferably of a metal or of reinforced resin construction to have sufficient strength and provide minimized friction of sliding movement on a snow runway. The handle 11 may be of wood, metal or reinforced resin material.
The front or guide part of the assembly represented by the ski device B has a longitudinally forwardly, somewhat striplike, substantially centrally planar, relatively narrow, runner part 20' also of metal or other suitable material. The front end portion 200 is shown turned upwardly for better guiding movement. A slightly downwardly projecting, centrally positioned and longitudinally extending ridge, runner orknife edge portion 20b is provided along the underside of therunner part 20. The knife orrunner edge portion 20b not only facilitates guiding the assembly, but gives thefront runner part 20 stability from the standpoint of minimizing slide slippage during its movement along a snowy pathway. A cross-extending abutment part, rung orfoot rail 22 is carried adjacent the front end portion of therunner part 20 on a centrally disposed upwardly extending triangular-shaped mounting-positioning block 21 that is secured, as by weld metal w, to the upper side of therunner 20. It will be noted that the rail orabutment 22 has end portions which extend transversely from opposite sides of thepositioning block 21, and that therunner 20 provides side strip or width portions along theblock 21 sufficient to receive the heels of the shoes of the rider C when the shoe soles are in an upwardly inclined resting position on the rung orrail 22. Force applied to either foot will tend to cause theski runner 20 to direct the ski assembly in that particular direction. Also, the hands of the rider C gripping the handle 11 may be employed to throw the weight of the rider C in the direction in which travel is desired.
A telescopic mounting arm or rod and sleeve assembly having cooperatingparts 25 and 26 extends substantially centrally of the length of the runner part in a backwardly upwardly inclined relationship, and has an open-sided, mounting collar or sleevepart 28 secured on its upper end for cooperating with the shovel handle 11. The lower part is shown as of rodlike construction and theupper part 26 is shown of cylindrical, sleevelike construction to slidably receive thelower part 25 therein. A spiral expansion spring 24 (see FIG. 4) is carried in a cooperating relation within thesleevelike part 26 to engage the inner end of therodlike part 25 and urge them in a shock-absorbing, outwardly extended relation with respect to each other. To retain theparts 25 and 26 in a flexibly slidable or telescopic relation with respect to each other, as shown in FIGS. 4 and 5, therod part 25 has a longitudinal, closed-end guide slot orgroove portion 25b that is adapted to receive an inner end of a threadedguide bolt 27 therein. As shown in FIG. 5, thebolt 27 is threadably carried within a threadedbore 26a by thesleeve part 26 to extend therethrough, with its inner, smooth cam or stud end portion in sliding engagement within theslot portion 25b. The lower end of therod part 25 is shown rigidly secured, as by weld metal w, to a central portion of therunner 20 adjacent to and behind theblock 21.
The mount 28 (as shown in FIG. 6) may be substantially half a segment of a cylinder that has a concave curvature complementary with respect to the curvature of the handle 11 to fit closely thereon. Agusset 28a is shown (see FIG. 4) secured by weld metal w to reinforce the connection between themount 28 and thesleeve part 26. The handle 11 may be provided with a pair of spaced-apart, through-extending, bore holes 11a (see FIG. 6) to receive bolts of bolt andnut assemblies 29 which extend across between opposite portions of theflangelike mount 28 to removably secure the shovel A to the ski device B. FIG. 7 shows a modified form of mount construction 28' in which the opposite walls 28'b of its mounting flange project slightly beyond the handle 11 in such a manner that the bolts of theassembly 29 may be employed on the outside of the handle 11, without the necessity of through extending bore holes therein. In both constructions, however, the bolt andnut assemblies 29 are tightened-down to securely carry the device B on the handle 11.
To increase the speed of operation of the device B, it may have its planar side portions at a slightly upwardly angular relation with respect to a central, longitudinal area or portion thereof.
