Problems solved by technology

At present, all snowboards, whether single board or double board, include a body made of polymer materials. Except for the upturned arc structure of the head and tail of the board, the bottom surface of the main part of the body between the head and tail is All plane structures are in contact with the snow surface. This invariable plane structure snowboard is limited by the bottom area and snow pressure point, which is not conducive to maximizing the sliding speed, nor is it conducive to reducing the weight of the skis and improving the strength of the skis. It needs to be further improved, so that skiing can be further developed

Embodiment 1

[0013] Embodiment one, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, it includes a snowboard body 1 composed of a head 11, a waist 12 and a tail 13 from front to back. The edge 14 extends to both sides and the rear end of the tail 13, and the bottom surface of the snowboard body 1 between the two edges 14 from the front end of the nose 11 to the rear end of the tail 13 is shaped as an upper concave arc with a high middle and low sides in the cross section. Surface 15.

[0014] The parallel depth difference between the high point in the middle of the concave arc surface 15 on the bottom surface of the ski body 1 and the low points on both sides is 3-8 mm.

[0015] The upper concave arc surface 15 on the bottom surface of the ski body 1 has the same width from the head 11 to the tail 13 (the width of the upper concave arc surface 15 does not change to ensure that the upper concave arc surface 15 will not produce additional resistance during skiing. glides be...

Embodiment 2

[0017] Embodiment two, such as Figure 5 , Figure 6 , Figure 7 As shown, the difference from Embodiment 1 is that the shape of the bottom surface of the snowboard body 1 between the two board edges 14 from the front end of the board head 11 to the middle or middle rear of the waist 12 is that the cross section is high in the middle and low on both sides. The upper concave arc surface 15 of the snowboard body 1 has an upper concave arc bottom surface.

[0018] The position where the upper concave arc-shaped surface 15 of the bottom surface of the snowboard body 1 transitions to a plane gradually inclines from the two sides of the snowboard body 1 to the middle part of the snowboard body 1 . The upper concave arc surface 15 of the bottom surface of the snowboard body 1 extends from 10 cm to 25 cm from the two sides of the snowboard body 1 to the middle part of the snowboard body 1.

[0019] The upper concave arc surface 15 on the bottom surface of the snowboard body 1 has t...

Abstract

The invention relates to a quick skiing board with an upper concave arc-shaped bottom surface. The quick skiing board comprises a skiing board body (1), wherein the bottom surface of the skiing board body (1) between two board blades (14) from the front end of a board head (11) to the back end of a board tail (13) is an upper concave arc-shaped surface (15) with cross section of which the middle part is high and both sides are low, or the bottom surface of the skiing board body (1) between two board blades (14) from the front end of the board head (11) to the middle part or middle-back part of a board waist (12) is an upper concave arc-shaped surface (15) with cross section of which the middle part is high and both sides are low; the bottom surface of the board waist (12) is a flat surface with a straight cross section, and the bottom surface of the board tail (13) is an arc-shaped surface with a straight cross section at the back part of the upper concave arc-shaped bottom surface of the skiing board body (1). The quick skiing board has the advantages that the skiing speed is higher, the weight is lighter, the strength is higher, and the use effect is better; the contact area between the skiing board and snow is increased under the condition of not increasing the widths of the skiing board head, the board waist and the board tail, the pressure on the snow surface is smaller, and the skiing speed is quicker.

Description

technical field [0001] The invention relates to sports equipment, in particular to a snowboard. Background technique [0002] With the continuous development of skiing and skiing equipment, the development of snowboards is also very fast. Generally speaking, there are two types of snowboards: single boards and double boards. The needs of the ski field, environment and personnel. At present, all snowboards, whether single board or double board, include a body made of polymer materials. Except for the upturned arc structure of the head and tail of the board, the bottom surface of the main part of the body between the head and tail is All plane structures are in contact with the snow surface. This invariable plane structure snowboard is limited by the bottom area and snow pressure point, which is not conducive to maximizing the sliding speed, nor is it conducive to reducing the weight of the skis and improving the strength of the skis. It needs to be further improved, so that...
