14 Claims.
This invention relates to wheeled skis and more particularly to a ski-like vehicle equipped with wheels whereby skiing may be simulated upon ordinary paved surfaces,
Roller skates must be used largely indoors since few outdoor surfaces such as pavements are sufficiently smooth to `provide satisfactory roller skating surfaces. In skating, furthermore, the skates are attached to the feet of the user in such a manner that one or the other of the skates is lifted from the skating surface. In skiing the action is dilerent from skating in that the skis are rarely lifted from the skiing surface, there being a weight transference and a sliding motion of the unweighted ski.
One object of thisinvention is t provide a wheeled ski for amusement and exercise of young and old in outdoor environment.
Another object of this invention is to provide a wheeled ski which is adapted for use on ordinary pavements and sidewalks.
Another object of this invention is to provide a wheeled ski in which means are provided to prevent the user from losing control of the skis.
Other and further objects of this invention will appear from the following description.
In the accompanying drawings which form part of the instant s-peciiication andwhich are to be read in conjunction therewith, and in which like reference numerals are used to indicate like parts in the various views:
Figure 1 is a perspective view of a pair of skis of this invention shown in use;
Figure 2 is a sectional view taken on the line 2--2 of Figure l;
Figure 3 is a front elevation on an enlarged scale of a pair of skis of this invention;
Figure 4 is a side elevation of the pair of skis shown in Figure 3;
Figure 5 is a top plan View of a pair of skis showing a different embodiment of this invention;
Figure 6 is a front elevation of the skis shown in Figure 5;
Figure '7 is a side elevation of the skis shown in Figure 5;
Figure 8 is a perspective view of a detail shown on an enlarged scale.
In general this invention contemplates the provision of a pair of elongated ski-like platforms each of which is provided with foot positioning means located adjacent the center of gyration of the masses. A xed wheel, which is rubber tired, is mounted on a fixed transverse axis adjacent the forward portion of the ski. A wheel supported ICI ESO-11.23)
from a bracket rotatable about a vertical axis is mounted adjacent the rear of each ski. Flexible means interconnect the skis to limit the outward separation of one ski from the other thus preventing the user from doing either a lateral or fore and aft split More particularly, referring now to the drawings, the ski body or platform il) may be made of any suitable material and is preferably somewhat elongated in shape as can readily be seen by reference to Figures l and 5. At the forward portion of the ski iii there is provided a pair of brackets i2 each of which supports an axle i4 around which is journaled a suitable wheel lli provided with a pneumatic or rubber tire I8. The forward portion of the ski l0, adjacent the wheel I6 may be provided with a guard 20. The rear portion of the ski platform lll carries a bracket 22 secured by rivets 24 or in any other suitable manner. A pin 26 is formed on a fork 28 and is journaled for rotary movement in the bracket 22. The fork 28 carries a rear axle 3Q .around which is journaled a wheel 32 provided with a pneumatic or rubber tire 3B. Adjacent .the axis of gyration of the assembly, there is provided foot positioning means 3S and 38 adjustably secured by bolts 4E! or the like. A plurality of openings @2 are provided in the ski body l0 so that the toe positioning member 556 and the heel positioning member 38 may be adjusted to accommodate feet of different lengths. Posi- ,tioned between the toe and heel member d and there is provided a resilient foot supporting member 44 which may be made of rubber or any other suitable resilient material. The surface of the foot supporting member or cushion Ml may be formed inclined toward the inter-ski space as may readily be seen by reference to Figure 2.
To limit the separation of one ski from another in order to prevent a user from doing the split, means are provided for flexibly interconnecting one ski with the other. In the embodiment of the invention shown in Figures l to 4, a pin 46 depends from the left side of the right ski platform IU and a pin 4t depends from the right side of the left ski platform Hl. A link 5B is pivoted to pin 45 and a link 52 is pivoted to pin 48. An intermediate link 5d pivotally connects links 59 and 52. The linking which is described further, prevents canting of one ski with respect to the other.
In the embodiment shown in Figures 5 to 7, instead of the links just described the skis are interconnected by a exible member 5e secured to the right side of left ski by pin 60 and to Y each forward step.
3 the left side of the right ski by pin 58. The flexible member 56 may be made of rubber, a coiled spring, wire rope or the like. When a flexible connection such as shown in Figure 5 is used, there is no stabilizing effect against tilting obtained in the embodiment shown in Figures 1 to 4 inclusive. In order to permit a user to mount the skis, there is provided a depending bracket S2 mounted on the right side of the left ski and a depending bracket mounted onthe left side of the right ski. The-bracket may be formed of elongated metal and may be secured in any suitable manner. As shown in Figure 7, the forward end of the bracket is secured by rivets 66, the rear end of the bracket being free. Besides limiting the motion of the skis to the amplitude shown in Figure 6 enabling their being mounted readily by a user, the brackets may act as brakes. By inclining the ski platforms as shown in-Figure 6, the lower portions ofthe brackets may engage the supporting surface frictionally to perform their braking function. In use, ski poles 58 -may be employed in amannerfsimilar-to skiing for propulsion, balancing and supporting purposes. rEhe propelling; motion necessary to keep the same skis in motion is a shuiliing walk asis commonly used inf skiing in which thev weight of the body is transferred concomitantly with `To change direction it is merely necessary toswing the platforms by inclining kthe weight of the body of the user in the necessary direction so that a resultant turning movement is provided. The skiis may be readily stopped'in the :embodiment shown in vFigure 3 by .the vmaneuver known as toeing in. I-
The wheeled ski `is verymaneuverable and the rubber tires enable it tol bev-employed on any paved surface with a maximum of comfort.
It will be seen that the objects of this invention have been accomplished and that a-wheeled ski is provided .which will afford exercise and amusement for young and old.
It will be understood that certain features and sub-combinations areof utility and may be employed without reference to other features and This is contemplated by and is within the scope of .the claims. It is further obvious that various changes maybe made in details within the scope of the "claims without departing from the spirit of the invention. 1t is, therefore, to be understood that-this invention is not to be limited to the specific details shown and described.
