The invention relates to a transport apparatus to be used on snow or similar grounds.

CURRENT STATE OF THE ART

All systems, national or foreign apparatus, with motor device and designed for forward motion or travel on snow or similar grounds, greatly differ in their characteristics and design which is the object of the present invention. US-A-2323526 discloses a sliding board in accordance with the preamble of claim 1 of this patent.

BRIEF DESCRIPTION OF THE INVENTION

The invention comprises an apparatus according to claim 1 of this patent. It consists of ski-type of board, though with greater width between the side edges. A motor has been installed on the same, which transmits motion by means of a chain or toothed belt and moves a caterpillar or endless belt system equipped with a gripping device on snow, and this belt or caterpillar is supported and guided on rollers which in turn are supported by the ends of their axis to a tilting structure which is provided with a shock absorbing device. The tilting structure-belt is mounted in an open space made on the board, longitudinally centered on the same, placed behind the motor. The tilting structure is provided with a fixing system which prevents the belt, if desired, from touching the snow. Supports permit placement of the feet so as to thus direct the board.

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION

It deals with a board (1) similar to a ski-board, though with wider dimensions than conventional ones. An open space has been performed on this board, which is longitudinally centered as regards the board and which starts approximately in the middle of the total length of the board and reaches almost the end of the same, with an approximate width of 3/5 of the total width of the board. Thus achieving a sliding board with front spatula, and as from approximately the middle of which, only two arms of the board continue up to the rear part. The two arms (2) rejoin at their end points, though on a higher plane (3) to that of the board, thus offering greater stiffness to the assembly and preventing that the rear union be a hindrance to the advancing motion over the snow.

On the area immediately in front of the open space, a support (4) is mounted, with axis device (13) in cross direction to the board. This axis supports a toothed roller (9) which couples with the teeth or attachment area inside the belt or caterpillar (7), which is also equipped with attachment devices (17) for the snow on its outside area. The roller has a pulley or pinion (5) attached at an end, which receives the movement by means of a toothed belt or chain which comes from the automatic variator system or automatic clutch, moved by the motor. From the ends of the roller (9) and pulley (5) carrier axis (13), two arms (6), longitudinal to board, grow perpendicularly to the axis, arranged consequently, throughout the length of all the open space, between both sides of the board. Said so called arms (6) or tilting structure, are joined in cross direction by various rollers (8) and offer the belt or caterpillar the support and correct trajectory to be followed. The tilting arms (6) are joined at their upper and front part, forming an arch (19), housing on its peak, an end of the shock absorbing device (10); the other end of the shock absorbing device is attached to a central support part (20). On the axis (13) of the roller (9), the arms and guide roller structure (6, 8) tilts, which in turn support the endless belt or caterpillar (7).

For placement of the feet on the board, said board carries two supports (21), one for each foot, placed approximately one on the first half and the other on the second half. Each support, is equipped with two support areas, placing a support area on the left side and the other on the right side, both support areas being joined by a crosspiece, in cross direction to the board, though this crosspiece is raised as regards the plane of the board, due to which, the support areas are joined on their upper part. This elevation serves on the rear support, to allow the correct operation of the belt-tilting structure assembly. Additionally, by pulling a handle (14) mounted onto the tilting structure (6) upwards, and simultaneously decompressing the spring of the shock absorbing device, either with a decoupling system of one of its axis or by means of a decompressing screw (11), it achieves that on accomplishment of this simple operation, the belt-tilting structure assembly (6, 7, 8, 9, 14, 15, 22) rises as regards the plane of the board, and remains suspended by hooks, locks or tieing devices placed on the tilting structure (15) and support of the foot (16). In this manner, the board is free and without the propulsion effect of the belt or caterpillar.

The assembly of the motor, fuel tank and automatic variator is installed on an area (18) prior to the support axis of the tractor roller. To accelerate the motor, and consequently, to achieve greater speed, there is installed an accelerating device which by means of a flexible small tube with an inside rope joined at one end to the carburettor and at the other end, joined to a trigger system with spring, which the driver of the board grips with his hand and adjusts at will.

To achieve a good use of the board, it shall be necessary to use boots which may be similar to those employed for practicing sports such as skiing or snow-boarding. Attachment devices shall also be installed on the supports of the board for the corresponding boots. Both the boots and the attachments are easily commercially acquired. Once the said material is correctly installed, we may make use of the board, tilting to one side or the other so as to perform left or right hand turns. For braking, it is necessary to stop the acceleration, followed by skiding on the edges until the board stops.

The apparatus is equipped with a detachable housing of light and resistant material (22) which is attached onto the tilting structure (6) and under the shock absorbing system (10), covering also the assembly made up of the belt-tilting structure, rollers and pulley, thus the driver is protected in case of a fall, at the same time, preventing the belt or caterpillar from hurling snow or other elements.
