Abstract

A shoe skate includes a single row of in-line wheels or rollers, mounted on the shoe as front and rear wheel units. The front wheel unit includes a bogie pivoted about a transverse axis and carrying leading and trailing wheels, enabling the skater to maintain these wheels in contact with the skating surface where the heel of the shoe is raised. The rear wheel unit is mounted on the heel of the skating shoe. A leaf spring bears on the opposite ends of the bogie, to maintain the bogie in a normal stable condition relative to the shoe.

Claims

1. A roller skate comprising

a shoe having a sole portion and a heel portion;

a front wheel assembly mounted at said sole portion; and

a rear wheel assembly mounted at said heel portion;

said front wheel assembly comprising;

a base plate attached to said sole portion having means defining a fixed pivot bearing underlying said sole portion;

an elongated bogie, having means defining a fixed pivot bearing intermediate its ends for coacting attachment to said plate pivot bearing; and

leading and trailing wheels rotatably mounted at the opposite ends of said bogie, and disposed beneath said sole portion;

spring means coupled between said front wheel assembly base plate and said bogie, for establishing a normal rotative position of said bogie relative to said base plate when the wheels are lifted from the skating surface;

said spring means comprising an elongated spring leaf secured rigidly to said base plate intermediate its ends, and having its opposite ends bearing on said bogie adjacent to the respective opposite ends thereof;

said rear wheel assembly comprising;

a base plate attached to said heel portion having means defining a wheel mount underlying said heel portion; and

a rear wheel rotatably mounted in said wheel mount;

said leading, trailing, and rear wheels being aligned in a single row about parallel axis of rotation.
