Roller skate capable of preventing sprain and fall injury

Abstract

The invention provides a roller skate capable of preventing sprain and fall injury. The roller skate comprises a roller skate body, a pulley frame, main pulleys, pulley penetrating nails and auxiliarybalance wheels. A pulley yoke is arranged below the roller skate body. A plurality of longitudinal main pulleys are arranged on the pulley yoke. Auxiliary balance wheels are arranged on the outer side of one wheel of the longitudinal main pulley blocks on the lower portion of the roller skate body. Pulley penetrating nails penetrate through the pulley frame, the longitudinal main pulleys and thecentral holes of the auxiliary balance wheels. Locking nuts are arranged at the other ends of the pulley penetrating nails or are fixed to the roller skate frame to lock the pulleys. The diameter of the auxiliary balance wheels is smaller than or equal to that of the longitudinal main pulleys. According to the invention, during the sliding process, when the body of a practicer is unbalanced, the auxiliary balance wheels touch the ground and form a triangle with other longitudinal main pulleys. Therefore, the body balance is kept, so that the foot sprain and the fall injury are prevented. Whenthe practicer masters the skating skill skills skillfully, the auxiliary balance wheels are detached. In this way, the roller skate is restored to be a single-row roller skate.

Description

technical field [0001] The invention relates to a roller skate for the sporting goods industry, in particular to a roller skate for preventing sprains and falls. Background technique [0002] Roller skating is a sport that young people like very much. There are two types of rolling wheels at the bottom of existing roller skates: single row and double row. Single row roller skates usually have a longitudinal arrangement along the central axis of the roller skates. At least two wheels are arranged, and the single-row roller skates have a good sliding experience and are convenient when doing various fancy movements such as turning, and are deeply loved by young people. [0003] Existing single-row roller skates are composed of a roller skating shoe body, a pulley fixing frame, a longitudinal main rolling wheel group, and pulley nails. There are bearings inside the main rolling wheels. The roller skating nails have two structures: one is double-sided nails, and the other is One...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the market and patent documents also have several kinds of roller skates to prevent sprained feet and falls, CN206715269 U and CN201186144Y, which announce two kinds of roller skates with auxiliary wheels, all of which have at least two main rollers in the longitudinal direction, one of which has two wheels. One auxiliary balance wheel is added on each side. The problem is that during the sliding process, the two auxiliary balance wheels on the inner side are very likely to collide, causing falls and increasing potential safety hazards.

[0006] US6,422,578B1 announces a single-row roller skate with auxiliary wheels. The auxiliary wheel is installed on one side, but because the auxiliary balance wheel is nailed on the main rolling wheel fixed frame, the human body weight will be reduced during use. When it is large, the load is very large, which can easily cause deformation of the main rolling wheel fixing frame, and the auxiliary balance wheel is displaced upwards, which cannot achieve the auxiliary balancing effect, and there are also safety hazards that are easy to sprain and fall
