Description

Prevent spraining foot and fall and hinder roller skate

Technical Field

The utility model relates to a sports goods trade skidding shoes especially relate to prevent spraining the foot and falling the skidding shoes of hindering.

Background

Roller skating is a very favorite sports for teenagers, the rolling wheels at the bottom of the existing roller skating shoes are mainly configured in a single-row rolling wheel mode and a double-row rolling wheel mode, the single-row roller skating shoes are generally provided with at least two wheels which are longitudinally arranged along the central axis of the roller skating shoes, the sliding experience of the single-row roller skating shoes is good, various fancy actions such as turning and the like are convenient, and the roller skating shoes are deeply loved by the teenagers.

The existing single-row roller skate is composed of a roller skate body, a roller fixing frame, a longitudinal main rolling wheel set and roller through nails, wherein a bearing is arranged inside the main rolling wheel, and the roller through nails have two structures: one is a double-sided through nail, one end of which is a big head of the through nail, the other end of which is provided with internal threads, and a locking bolt is matched with the internal threads to lock a pulley; one is a single-side through nail, one end of which is provided with a big head of the through nail, and the other end of which is provided with external threads, and the single-side through nail can be directly screwed on an internal thread hole on a pulley fixing frame to lock the pulley. The single-row roller skate is characterized in that at least two rolling wheels which are arranged on the central axis in a longitudinal arrangement mode are on the same straight line, so that the single-row roller skate is unstable, easily sprains feet and falls to cause accidents, and particularly for beginners, when the single-row roller skate is worn to learn roller skating, the body balance is not well mastered, and once the body slightly leans forwards, the rolling wheels at the soles can slide backwards; if the body slightly leans backwards, the foot rolling wheels slide forwards, so that a beginner is difficult to keep the balance of the body forwards and backwards, and can easily bend feet and tumble; the front and back directions of the roller can be flexibly rolled, so that when a beginner needs to pedal with feet for acceleration, the force cannot be applied towards the right back direction of the body like a normal walking posture, but needs to be applied towards the outer side back of the body, so that the sole of the foot cannot slip, and the power required for acceleration is obtained.

In summary, the conventional single-row roller skate is difficult for beginners to quickly master the use skills of the roller skate and experience the interest of roller skating as early as possible. Especially, the beginners have weak self-protection ability when being children, are most prone to sprain feet and fall hurt bodies, and are pain points for parents to object children to learning to slide.

In order to solve the above problems, there are several roller skates for preventing spraining and hurting feet in the market and patent literature, CN 206715269U and CN201186144Y, which disclose two roller skates with auxiliary rollers, each of which is formed by adding an auxiliary balance roller on each of two sides of at least two main rollers in the longitudinal direction, and there are problems: in the sliding process, the two auxiliary balance wheels on the inner side are easy to collide, so that falling injury is caused, and potential safety hazards are increased.

US6,422,578B1 discloses a roller skate with auxiliary wheels, which is provided with auxiliary wheels at one side, but because the auxiliary balance wheel is fixed on the main rolling wheel fixing frame by the through-nails, when the weight of a human body is large in the using process, the load is large, the main rolling wheel fixing frame is easy to deform, the auxiliary balance wheels are staggered upwards, the auxiliary balance function cannot be realized, and the potential safety hazard of easily spraining and hurting feet and hurting is also existed.
