Abstract

PROBLEM TO BE SOLVED: To make easily performable deceleration timely by curving the main body of a snowboard upward in the range toward a rear end starting from a portion where the load of the rear foot is applied in the basic posture for sliding to form a bottom face portion kept in no contact with the snow surface, and fitting an antiskid material to the bottom face portion kept in no contact with the snow surface. SOLUTION: The main body 1 of a snowboard is curved upward in the range toward a rear end 5 starting from a portion where the load of the rear foot is applied when a rider stands with both feet faced laterally with respect to the tip 8 and uniformly applies the body weight in the basic posture for sliding, and a portion kept in no contact with the snow surface is formed as a deceleration face 6. The whole deceleration face 6 is scraped to form a fitting portion of an antiskid material 7, then the antiskid material 7 formed with a raw material such as urethane, rubber or a plastic into a mesh shape or a frictional shape in an irregular layout is fitted to the deceleration face 6. A footstool for the rear foot to be mounted with the rear foot for assuming the basic posture is fitted at the fitting portion of a rear foot boot binding on the upper face of the main body 1 of the snowboard.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snowboard speed reducer.

[0002]

2. Description of the Related Art Conventionally, in order to decelerate a snowboard which has been straight downhill, an edge is applied in a skid state while turning the snowboard whose tip is directed downward on a slope from side to side. The operation of rotating left and right is also the operation of deceleration. Some skis and sleds have a speed reducer in which an edge or a protrusion is attached to the rear end.

[0003]

This has the following disadvantages. I. If rotation operation is not possible, it will not decelerate. The higher the speed, the more difficult the rotation operation is for beginners. That is, if the speed becomes high against the intention, it becomes difficult to rotate, decelerate, and stop, and if it is forcibly performed, it is easy to fall. Since the snowboard has both feet positioned almost sideways with respect to the tip, it may fall to the valley side of the slope due to failure of the rotation operation, and falling at a high speed to the slope valley side may be a blow of the face or the back of the head. There is danger. B. Even if edges or protrusions are attached to the rear end of the snowboard, the weight will be weighted and the bottom part in contact with the snow will be a sliding surface, so not only will there be little deceleration effect, but also in the side slip state during rotation operation, There is a danger that the edges and protrusions of the edges may be inadvertently caught on the bumps on the slope. The present invention has been made to solve the above drawbacks.

[0004]

Means for Solving the Problems A snowboard body (1) placed on a snowy surface, with both feet standing sideways with respect to a tip (8), equally weighing, and taking a basic posture when skiing. Then, starting from the weighted portion of the rear foot, the rear foot (5) is curved so as to rise toward the rear end (5), and a bottom surface portion not in contact with the snow surface is provided. A deceleration surface (6) is provided by attaching a non-slip material (7) that generates friction to a bottom surface portion not in contact with the snow surface. The starting point of the ascent to the rear end of the bottom surface is the boundary (3) between the portion of the bottom surface that is in contact with the snow surface and the portion that is not in contact with the snow surface, the leading end side being the sliding surface (10), and the rear end side being the deceleration surface (6). The present invention provides a snowboard with a deceleration surface having the above configuration.

[0005]

Embodiments of the present invention will be described below. I. With the body of the snowboard (1) standing with both feet sideways against the tip (8), applying weight evenly, and taking the basic posture when sliding, starting from the part where the weight of the rear foot is applied, It is curved so as to rise toward the end (5), and a portion that does not contact the snow surface corresponding to the deceleration surface (6) is provided. When placed on a plane, the starting point of the ascent is the boundary (3), the tip (8) whose bottom surface is in contact with the plane is the sliding surface (10), and the rear end (5)
The side becomes the deceleration surface (6). B. The entire deceleration surface (6) is shaved to provide a mounting portion for a non-slip material (7). C. A non-slip material (7) made of a material such as urethane, rubber, plastic, or the like having a shape in which friction occurs, such as a mesh or an array of irregularities, is attached to the speed reduction surface (6). D. On the upper surface of the main body (1) of the snowboard, a footrest (11) for a rearfoot, which has a horizontal upper plate on which a rearfoot is mounted to take a basic posture, is mounted at a mounting portion of a rearfoot boot binding. With the forefinger of the hind foot resting on the boundary (3) of the bottom surface, the inside of the foot from the thumb to the inside of the heel weights the rear part (2) of the running surface, and the foot from the little finger to the outside of the heel The outer side is arranged at a position where the front part (4) of the deceleration surface is weighted. E. With the forefoot tread (12), the height of both feet is the same. F. Edge (9) on both left and right edges with respect to tip (8)
Attach. G. The structure of the running surface (10) is the same as a conventional snowboard. The present invention has the above configuration. When the present invention is used, the step for the rear foot (11) and the step for the front foot (12)
The feet are fixed with the above binding, the weights are equally applied to both feet standing sideways to the tip (8), and both knees are slightly bent to take a basic posture. Then, when the tip (8) is directed downward on the slope, the sliding surface (10) starts sliding downhill in a state of contact with the slope (13). The deceleration surface (6) does not touch the slope (13). This means that when the knees of both feet are slightly squeezed, the rear feet are weighted from the thumb to the inside of the heel, the front feet weight the center of the running surface (10), and the rear feet weight the rear part (2) of the running surface. Because. In deceleration, the upper body is tilted backward, the forefoot knees are extended, and the hindfoot knees are bent deeply to take a posture in which the weight is applied to the outside of the foot from the little finger of the hindfoot to the outside of the heel. Then, the front portion (4) of the deceleration surface comes into contact with the slope (13), the body (1) of the snowboard tilts toward the rear end (5), and the sliding surface (10) floats and does not come into contact with the slope. Anti-slip material for deceleration surface (6) (7)
Creates friction and begins to decelerate. When rotating and stopping after deceleration, return the back tilted upper body to the basic posture,
After the body (1) of the snowboard is inclined toward the tip (8) and the sliding surface (10) comes into contact with the slope (13), the tip (8)
The conventional operation is performed on the left and right side edges (9). As shown in FIG. 5, when a step (14) is formed upward at the boundary (3) and then curved to provide the deceleration surface (6), a thick non-slip is attached. This can prevent snow clogging and enhance the deceleration effect.

[0006]

According to the present invention, the vehicle can be decelerated from a straight downhill state by a simple operation of tilting the upper body backward. Switching between acceleration and deceleration is clear, and the slip is not in the way during operations other than deceleration. The operation of rotating and stopping from a high speed is safe and reliable if performed by a conventional method after sufficient deceleration.
