Abstract

An inline skate including air tubes for absorbing shock transmitted to respective wheels so as to use rigid wheels, and to protect the knees and ankles from shock. The inline skate includes a frame having insertion holes receiving shock absorbers, guide recesses, and brackets for defining desired spaces, a wheel holder having supporting plates in which the wheels are coupled to and supported by the sides of the supporting plate and inserted into the guide recesses so that the wheel holder is moved upward and downward by applied external force so as to transmit the external force to the shock absorbers, and the shock absorbers inserted into the insertion holes and filled with air so as to absorb the external force when the wheel holder moves vertically. Since the wheel holder moves vertically along the surface of the uneven ground, the user can balance in safety.

Claims

1. An inline skate comprising:

a wheel supporting part installed to the lower side of an outsole of an ordinary shoe;

a plurality of wheels coupled and supported to the inner lower sides of the wheel supporting part by shafts;

a rotatable supporting holder coupled to the rear upper side of the wheel supporting part by a shaft, and coupled to a connecting protrusion protruded from the outsole of the ordinary shoe so as to prevent the wheel supporting part from being separated from the outsole;

a frame constituting the wheel supporting part, and having insertion holes formed at the inner upper sides of the frame, a plurality of guide recesses in the direction perpendicular to the insertion holes, and brackets, protruded between the guide recesses, for defining desired spaces;

a wheel holder having supporting plates in which the wheels are coupled to and supported by the sides of the supporting plate, and inserted into the guide recesses so that the wheel holder is moved vertically by applied external force; and

the shock absorbers inserted into the insertion holes and filled with air so as to disappear absorb the external force when the wheel holder moves vertically.

2. The inline skate as set forth in claim 1, wherein each guide recess has a connecting protrusion protruded from the inner upper side of the guide recess to a certain height, and a longitudinal guide hole formed at the lower side of the guide recess.

3. The inline skate as set forth in claim 1, wherein each supporting plate has a guide hole formed at the upper side of the supporting plate, into which the connecting protrusion is inserted and guided vertically, and a connecting protrusion formed at the outer lower side of the supporting plate and inserted into the guide hole of the guide recess.

4. The inline skate as set forth in claim 2, wherein each supporting plate has a guide hole formed at the upper side of the supporting plate, into which the connecting protrusion is inserted and guided vertically, and a connecting protrusion formed at the outer lower side of the supporting plate and inserted into the guide hole of the guide recess.

5. The inline skate as set forth in claim 1, wherein each shock absorber includes:

a housing made of soft synthetic resin;

predetermined spaces formed at the sides of the housing;

air tubes installed in the predetermined spaces;

a cover sheet wrapped around the housing; and

a connecting part made of the same material as that of the housing, disposed at the intermediate portion of the housing, and integrated with the housing.
