Definitions

  • the present invention relates generally to inline skates, and particularly to inline skates that combining a one-way roll stop device and a cushion for providing the inline skates with superior braking effect during sliding as well as with more forceful acceleration holds. Thereby, an improved structure of inline skates with ergonomics, exercise-injury prevention, and comfort is provided.
  • Inline skating is a rising roller-skating exercise.
  • a variety of types has developed including mainly recreational, figure, cross-country, acrobatic, and speed.
  • Special structures are designed for cross-country and speed inline skates to meet their speed demands or requirements by special environments.
  • extraordinary and long-term trainings are required to handle and use them appropriately.
  • the basic structure and function thereof similar to recreational inline skates, details of the inline skates of these types are not described here. In the following, recreational, figure, and acrobatic inline skates are described in detail.
  • the structure thereof includes a boot, a base under the boot, and a plurality of wheels adapted on the base. There is no front brake pad.
  • a forward force for the left leg is given.
  • Owing to the larger wheel diameter with the longer span it is laborious to press and push slantingly both legs alternately for maintaining sliding for a long time. In addition, it violates ergonomics as well.
  • recreational inline skates do not provide effective braking disposal. Some brands add rear brake pads behind the roller skates.
  • a front brake pad is adapted at the first-wheel position of a recreational inline skate, and all wheels are shrunk and arranged behind the front brake pad.
  • the figure inline skate slides slower and unstable.
  • the center of gravity leans forward. Slight incaution results in touch of the front brake pad on the sliding leg on the ground, which is very dangerous because it will cause the player trip forward.
  • acrobatic line skate no brake is adapted thereon because a brake device that is like the one on a recreational or a figure inline skate obstructs absolutely acrobatic movements and thereby results in danger.
  • a brake device that is like the one on a recreational or a figure inline skate obstructs absolutely acrobatic movements and thereby results in danger.
  • an acrobatic inline skate need not a brake device. In fact, tumbles when wearing acrobatic inline skates occur frequently. Some severe injuries even happened.
  • T-stop refers to turning aside and opening both legs abruptly during sliding to make both legs perpendicular to the direction of sliding for attaining braking effect.
  • this skill needs long-term practices. Slight incaution tends to result in tumble and accidental injuries such as scrapes, collision injuries, and sprains. Besides, the skill violates ergonomics.
  • T-stop is not applicable in all fields. If the field is slightly slippery, unsmooth, or has too much grip, falling over tends to happen. Thereby, improved brake device of inline skates is desired for solving inconveniences in operations and problems of frequent exercise injuries.
  • the present invention provides inline skates complying with ergonomics, being exercise-injury preventive, shock absorptive, and comfortable.
