Abstract
A structure of inline skates is provided, the structure of inline skates includes a cushion device, a wheel with an annular ratchet wheel on its side, and a pawl assembly. By using the user's weight to press down the structure of present invention, the wheel with the annular ratchet wheel on its side engages the pawl assembly, which stops the wheel with the annular ratchet wheel on its side from rolling in one direction, and the wheel with the annular ratchet wheel on its side can roll in another direction. Thereby, the structure of inline skates is more ergonomic and exercise injuries can be prevented. In addition, a brake is provided for providing shock absorption and as a fulcrum to make more powerful acceleration. Besides, automatic support upright is also provided for avoiding tumbles.

A structure of inline skates, comprising:
- a base, comprising at least one connection member, an orientation member, and two side plates being disposed on both sides of the connection member, respectively with a plurality of pivotal holes thereon, a front end or a rear end of the least one side plate having a long pivotal bore;
- a wheel set, comprising a front wheel and a rear wheel, the front wheel and the rear wheel being pivoted on the side plates, the front wheel and the rear wheel having at least one bearing respectively;
- at least one one-way roll stop device, comprising an annular ratchet wheel and a pawl assembly, the annular ratchet wheel being fixedly coupled to the side of the front wheel or the rear wheel, the annular ratchet wheel having a hole to form an annular shape, the diameter of the hole being greater than the diameter of the bearing, the hole being opposite to the bearing, the pawl assembly being disposed on the base, the annular ratchet wheel being disposed opposite to the pawl assembly, the annular ratchet wheel and the pawl assembly being spaced from one another, wherein the orientation member is utilized to orientate the pawl assembly for making the pawl assembly space from the annular ratchet wheel when the position of the base corresponding to the front wheel or the rear wheel is not pressed;
- and
- at least one cushion device, including a sliding block and sleeve assembly and a spring, the sliding block and sleeve assembly including a sleeve with a trough adapted for accommodating the spring, and a pivotal hole being disposed at the lower end of the sleeve, a rear side of the sleeve including a sliding block with a shorter length and corresponding to the long pivotal bore, the sliding block being inserted to the long pivotal bore, one end of the cushion device being disposed on the base, and the other end of the cushion device being connected to the front wheel or the rear wheel by passing a screw bolt assembly through the pivotal hole of the sliding block and sleeve assembly, the long pivotal bore of the side plate and the front wheel or the rear wheel;
- wherein when a position of the base corresponding to the front wheel or the rear wheel is not pressed, the annular ratchet wheel and the pawl assembly are not contacted to each other and the front wheel or the rear wheel can roll forwards or backwards, and when the position of the base corresponding to the front wheel or the rear wheel is pressed, the annular ratchet wheel contacts the pawl assembly thereby stopping the front wheel or the rear wheel from rolling in one direction, and the front wheel or the rear wheel being able to roll in another direction.
