United States Patent G 3,282,598 LAND SKIER Charles W. Goodwin, Box 34, Charlemont, Mass. Filed Aug. 27, 1964, Ser. No. 392,487 2 Claims. (Cl. 280-112) slopes are being operated with artificial snow, where the weather is proper, at great expense.
It is a purpose of the within invention to provide a device for permitting dry-land skiing on winter slopes during the warm summer months.
It is a primary object of the within invention to provide a dry-land skier that permits maneuverability.
It is another object of the within invention to provide a skier that permits the user to employ the skills that he would normally employ with winter skiing.
It is still an additional object of this invention to provide a summer skier that is low in the cost of manufacture.
It is yet an additional object of the within invention to provide a summer skier that is simple in construction and yet durable.
These and other objects are obtained by the use of specially-shaped rollers, a plurality of which are mounted between frame members that are in horizontal as well as angular planes, and a drag shoe for controlling speed.
The various objects and features of this invention will be fully understood from the following detailed description of a typical, preferred embodiment and application of the invention, throughout which description reference is made to the accompanying drawings, in which:
FIGURE 1 is a top perspective view of the skier.
FIGURE 2 is a side elevational view of the skier.
FIGURE 3 is a front elevational view of one of the typical rollers.
FIGURE 4 is a top elevational view of a portion of the skier above the drag shoe.
The skiing device has two side rails 1. A plurality of rollers 3 are mounted between the rails 1 as shown in the various figures of the drawing. The rollers have a central opening through which is mounted a free-moving shaft 6a which is threaded at each end and attached to the nuts 6. A washer 6b is located between the rail 1 and the nut 6 for locking the nut 6. Mounted at the rear end of the skier is a drag shoe 2. The drag shoe 2 is mounted on the screws 7. The drag shoe 2 is located between the two rails 1 at the rear of the rollers 3. Connected above the rollers and between the rails 1 is the shoe plate 4. The shoe plate 4 is connected by screws or other fastening means to the rails 1 at the top thereof. There are eyes which are secured to the shoe plate 4. Shoe plate 4 is connected by screws or other fastening means to the rails 1 at the top thereof. Eyes 5 which are secured to the shoe plate 4 are for the purpose of connecting straps or other fastening means for placing the skhers shoe securely in position on the skier device atop shoe plate 4.
Of extreme importance in the design of the device are the planes of the various parts. There is the plane 8 of the front rollers. It is noted that the front portion of the rails 1 have an upswing. The rollers 3a at the front follow the plane 8 of the upswing. There is a horizontal flat plane 9 which is the plane beneath the foot plate 4. To the rear of plane 9 is the plane 10 of the drag shoe 2. The plane 10 of drag shoe 2 is longer and not quite as Patented Nov. 1, 1966 steep as plane 8 and, as can be seen in FIGURE 3, runs upwardly to the rear instead of upwardly .to the front (the plane 8 runs upwardly and forward).
The rollers 3 have two separate planes. The center of the roller is much larger in cross-section (larger diameter) than the ends of the roller 3 as can be seen in the views of FIGURE 3 and FIGURE 4. In the view of FIGURE 3, the plane to the right of the rollers is indicated by the numeral 11 while the plane to the left of the roller is indicated by the numeral 12. The horizontal plane 9 is shown just beneath 11 and 12. The dotted lines between the planes in FIGURE 3 show the approximate angle of the rollers from their center as determined by a horizontal plane.
The rollers 3 and 3a are similar. The rollers 3a are the rollers in plane 8, while the rollers 3 are the rollers in the horizontal plane 9. The rollers 3 and the rollers 3a are similar in structure.
In the view of FIGURE 4 the support of a typical roller 3 (or 3a) is shown. The shaft or axle 6a which passes through '3 is shown in FIGURE 4. The washer 6b is between the frame 1 and the nut 6.
It is contemplated that the shaft 6a could be a sleeve or bearing which does not pass through the roller 3. The roller 3 would then spin within the openings in the frame 1 at the same time that the bearings or pins would spin. The rollers 3 and 3a must be easily rotatable.
The device may be made from strong wood, aluminum, or other similar metal, synthetic plastic or a material that is strong and will stand up under abuse without departing from the spirit of the invention. On an assembly basis the parts could be manufactured from molds and jigs.
In operation, the skier applies the ski device to his shoe by placing his foot on the plane 4. Straps are passed through the eyes 5 over the shoe to secure the shoe or ski foot to the device. When each shoe has been secured to the device, the skier is ready to ski on dry land. It is to be noted in the previous description that there are five planes in the device, four inclined and one horizontal. When the skier presses his weight forward, the center of gravity is on the fiat horizontal plane 9. In the embodiment shown, this plane 9 consists of six free-wheeling rollers '3. Forward of plane 9 as already stated is the inclined plane 8. The purpose of plane 8 is to permit deflection for any ground irregularities, stones, or other objects. The inclined plane 10 to the rear of the rollers 3 gives the drag shoe 2 sufficient clearance 'while the users weight is pressed forward. However, when the users weight is shifted to the rear of the device, the center of gravity is taken from the rollers 3 and plane 9 and placed upon the drag shoe 2. This change of gravity has the effect of giving a stabilizing effect for slowing down, turning, or stopping. There is an analogy between plane 9 and plane 10. Water Skiing is a good example. The rollers 3 and 3a allow for ample speed to be obtained. When sufficient speed is attained, the user will then throw his weight to the rear of the device so that the drag shoe 2 will come into play. The drag shoe 2 itself will then act with amazing effect as a ski when there is a fair degree of fall line. The motion forward has been discussed. However, in skiing there is required maneuverability to the side, which is known as lateral movement. The shape of the planes 11 and 12 on the rollers 3 allows lateral movement of the device. The inclined angles of these planes also permit almost friction-free rolling with no edge or irregularities to catch or throw the skiers leg. The lateral angle of the rollers 3 and 3a, which is controlled by the inclined planes 11 and 12, permits the skier to make a sharp turn either to the right or left at a fair rate of speed without being thrown. Similar to real skiing, the skier throws his weight to either the right or left side.
Certain dimensions in the drawing have been exaggerated and a 'change in size or shape would be within the spirit and scope of this invention.
In consideration of the foregoing disclosure I claim.

Aland skier having two parallel rails, a plurality of rotating devices connected between the said rails, said Intating devices having their bottom surfaces extending below the bottom of said rails, the bottom of said rails having an upward plane in the front and an upward extending plane to the rear with a horizontal plane therebetween, said rotating devices at the front of the. said rails being in the upwardly extending plane, a braking device for controlling speed being located between the rear of the rails andextending below the lower surface of the rails, and a plate for securing said rails together and supporting a user.
