Description

Anti-skid pad for high jump sports

Technical Field

The utility model relates to a slipmat technical field particularly relates to a slipmat for high jump motion.

Background

The high jump sports is a common track and field sports, which is composed of rhythmic running, single-foot jumping, crossing the cross bar and landing, and the like, and the achievement is calculated by the height of crossing the upper edge of the cross bar. In the daily training in-process, in order to prevent to cause the injury to sportsman or the student of training when falling to the ground, lay one deck cushion through the surface that can be in the subregion of training place, play the effect of buffering and protection. At present, the commonly used elastic protection pads are protection pads formed by independently cutting or forming rubber pads or plastic foaming materials, but in the actual use process of the protection pads, the anti-slip performance of the rubber pads is better, the anti-slip performance of the plastic foaming material protection pads is poor, the plastic foaming material protection pads can easily slip and shift in the frequent training process for many times, partial falling areas possibly left by athletes are caused, and the accidental damage of the athletes can be caused.

Meanwhile, the traditional protective mats for high jump sports and gymnastic sports also adopt soft materials similar to yoga mats to protect the ground, but in practical use, the yoga mats are usually made into light and soft cushion layers by adopting rubber foaming, TPE foaming and PVC foaming, are suitable for light sports and are particularly suitable for indoor use in flat and better environments, but have certain strength and impact properties for outdoor sports such as high jump and gymnastic, and are difficult to play a role in supporting and protecting, and the soft structures are very easy to cause damage to soles, knees and other possible ground positions of athletes under the condition that the bottom surfaces of the soft structures are fine or stones, and under the outdoor use environment, the yoga mats have poor ultraviolet resistance, wear resistance and water resistance and very limited service life.

In traditional protection pad, there is still a class of portable, folding protection pad, for example the sports training that the surrounding layer adopts polyurethane cladding, inside uses the rubber pad buffer layer is with safe protection pad, and it is comparatively convenient to carry in relative terms, can fold and open the use moreover, but its edge and inside have the plastics or the metal structure of stereoplasm, especially folding structure part, usually realize with the help of stainless steel or other metalworks, when falling to the ground, cause sportsman's damage very easily.

For a protection pad, two basic functions are energy dissipation buffering and skid prevention, and skid prevention is relatively easy to find, but in terms of buffering function, an ideal design is not found at present. For example, wu lianzong proposes a protection pad fabric for gymnastics training, wherein the middle layer of the protection pad is provided with a rubber sleeve and a spring structure is designed in the rubber sleeve to realize a buffering function, and the structure is designed by means of a spring mattress, but the structure is complex, the cost is high during actual industrialization and mass production, and the difficulty of the preparation process is high. Also like a parallel bar exercise protection device proposed by Yangbaoqiang et al, it has set up silk cotton layer, foam layer, emulsion layer, spring housing, spring, protects complicated structural design such as spine sponge, stereoplasm sponge, is difficult to use high strength application under the outdoor environment, and with high costs, the technology degree of difficulty is big, excessively complicated when the industrial production is made moreover.

Therefore, in conjunction with the above analysis, it is desirable to design and manufacture protective pads that are simple in construction, soft and rigid, and not suitable for use with rigid plastic or metal structures to reduce the potential for injury during exercise and training.
