Snow raft having a plurality of adjustable speed control studs

Abstract

A snow raft comprises a plurality of adjustable speed control studs to control the speed of the raft wherein adjustments are made by way of threading and unthreading the studs located within threaded sockets.

Claims

1. A snow raft having a plurality of adjustable speed control studs to control the speed of the raft wherein adjustments are made by way of threading and unthreading the studs located within threaded sockets.

2. The raft of claim 1 wherein the raft is made using a rotomoulding process.

3. The raft of claim 1 is comprised of a plurality of built-in seats from which a backrest extends integrally therefrom.

4. The raft of claim 1 wherein a rudder member is located on the underside of the raft on one of its sides and is used for reducing sideways sliding and help keep the raft on course.

5. The raft of claim 1 wherein at least one carrying handle is attached to a side of the raft for carrying the raft.

6. The raft of claim 1 wherein a pull cord is attached to the front of the raft.

7. The raft of claim 1 wherein different shapes of studs can be used at once to further customize the speed according to snow conditions.

8. The raft of claim 6 wherein studs have various shapes comprising but not limited to hexagonal, octagonal, circular, flat head, and rounded head.

9. The raft of claim 6 wherein the studs have a threaded portion configured to thread into the threaded socket, and a head portion that interacts with the snow.

10. A solid body, monohull raft is comprised of a plurality of built-in seats from which a backrest extends integrally therefrom; a plurality of adjustable speed control studs to control the speed of the raft wherein adjustments are made by way of threading and unthreading the studs located within threaded sockets.

DETAILED DESCRIPTION

[0021] A raft (10) has a main body (12) configured and shaped similarly to an inflatable raft but preferably made from a rigid material. It has a plurality of built-in seats (14), further comprised of a back rest (16), and carrying handles (18), which can also act as securing handles for the passengers.

[0022] A rudder member (20) is located on the underside of the raft (10) on one of its sides and is used for reducing sideways sliding and help keep the raft (10) on course,

[0023] Retractable speed control studs (24, 24) control speed of the raft (10) and are adjustable and interchangeable according to the type of snow conditions. For example, when snow is hard and icy, speed needs to be reduced as much as possible to keep the raft (10) going at a safe speed. In order to do so, multi faceted studs (24) (for example a heaxgonal stud as shown in FIG. 3b) are used. When snow conditions are less slippery, a smoother round faced stud (24) can be used as shown in FIG. 3c. In both cases, the studs (24, 24) can be protracted or retracted by threading in unthreading them within their threaded sockets (22). When snow is soft and sticky, friction can be further reduced by removing all studs (24, 24) from their sockets (22), as shown in FIG. 3d. Also, different shapes of studs (24, 24) can be used at once to further customize the speed according to snow conditions. The studs (24, 24) have a threaded portion (28) configured to thread into the threaded socket (22), and a head portion (30) that interacts with the snow.

[0024] The raft (10) is made using a rotomoulding process which allows for it to be a single, monohull structure, which makes it even stronger than if made from several attached parts. There are of course a few attached parts such as the carrying handles (18) the studs (24, 24), the rudder member (20) and a pull cord (26).

[0025] The advantage of a solid body raft (10) over an inflatable one has to do with longevity and better endurance to cold weather and other factors such as air pressure variations over difference in temperatures which can affect the stiffness of an inflatable raft more in cold weather than in warmer weather since body heat of friction can have a much greater effect when at freezing temperatures.

[0026] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0027] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
