External-tying universal type roller-skating elastic device

Abstract

The invention relates to an external-tying universal type roller-skating elastic device, which is characterized by comprising an adjustable nylon binding belt, an upper bottom, a screwing-in type spring clamp, an extruding type spring clamp, a middle-convex type spring, a lower bottom, a wheel groove, a spring buffering wheel, an outward-inclining trapezoidal rubber spring buffering pad, a nylon buckle, a belt buckle shaped like a Chinese character 'ri' (meaning sun), a binding belt, a screwing-in door, a fastening bolt, an extruding groove, a screwing-out port, an extruding plug, a bolt, a nut resilient sheet, a spring fixing shaft, a buffering spring, a spring groove, a shaft, a pulley, a shaft fork and a cross plate, wherein the adjustable nylon binding belt is fixed on the upper bottom; the middle-convex type spring is fixed between the upper bottom and the lower bottom by the screwing-in spring clamp and the extruding type spring clamp; the middle of the lower bottom is fixedly provided with the wheel groove with the spring buffering wheel, and the periphery of the lower bottom is provided with the outward-inclining trapezoidal rubber spring buffering pad in an attaching manner. The elastic device has the advantages that the stability and the shock-absorbing performance are good, the function is strong, the use is convenient, the structure is novel and unique, and the like. Most importantly, the elastic device is not directly contacted with foot, the jump capability is greatly increased under the premise of not influencing the advantages of the comfort of shoes and the like, and one elastic device can be used by more than one person, so that the application range of the elastic device is greatly expanded. In addition, the device can be simply used as a roller-skating shoe only by slight modification.

Description

technical field [0001] The invention relates to an externally bound universal roller skating elastic device, which belongs to the technical field of sporting goods. Background technique [0002] Jumping farther and jumping higher has always been the two wishes of people, especially sports athletes, and the help of elastic shoes to playing basketball is self-evident. For a long time, footwear designers have also made a lot of explorations and achieved many results. However, spring shoes have very high requirements on stability, safety, comfort, etc., which is also an important reason why spring shoes cannot be mass-produced and popularized. [0003] Existing elastic device kind is a lot, and some is also done very well, but above-mentioned problem still exists more or less. And most of the existing elastic devices are to add springs or the like on the soles to achieve the purpose of strengthening the springing force, and its springing force and application range are all sub...

AI Technical Summary

Problems solved by technology

And most of the existing elastic devices are to add springs or the like on the soles to achieve the purpose of strengthening the springing force, and its springing force and application range are all subject to great limitations, and problems are prone to occur.

[0004] There are many roller skates now, but few of them link the bounce device with the roller skating device. Requirements such as safety and stability make it impossible to combine the two devices into one.
