Abstract

A roller skate with a roller frame for the spring suspension of a roller axle on the sole plate of the skate, in which the roller frame comprises a carrier holding the roller axle and pivotally connected to the sole plate and a U-shaped spring bracket connected to the sole plate and to the carrier.

Claims

1. In a roller skate having a sole plate, rollers and roller axles, a roller frame from the spring suspension of a roller axle mounted on said sole plate, said roller frame comprising a carrier supporting the roller axle and pivotally connected to said sole plate, a U-shaped spring bracket connected to said sole plate and said carrier, said carrier being connected to one arm of said spring bracket through a draw-screw, and an adjuster bolt threaded into a central bore defined in said drawscrew, said adjuster bolt being located between the arms of said spring bracket.

2. In a roller skate having a sole plate, rollers and roller axles, a roller frame for the spring suspension of a roller axle mounted on said sole plate, said roller frame comprising a carrier supporting the roller axle and pivotally connected to said sole plate, a U-shaped spring bracket connected to said sole plate and to said carrier, and an adjuster bolt located between the arms of said spring bracket for adjusting the pre-load of said spring bracket.

3. A roller skate as claimed in claim 2, in which there is a limited amount of play between said adjuster bolt and the arms of the spring bracket.

4. A roller skate as claimed in claim 3, in which said adjuster bolt is provided with a shoulder which seats in a countersunk bore formed in one arm of the spring bracket and covered by the sole plate.

5. In a roller skate having a sole plate, rollers and roller axles, a roller frame for the spring suspension of a roller axle mounted on said sole plate, said roller frame conprising a carrier supporting the roller axle and pivotally connected to said sole plate, a U-shaped spring bracket connected to said sole plate and to said carrier, a fixing bracket mounted to said sole plate for supporting a stop member or weights, and an adjuster screw interposed between said fixing bracket and said carrier for adjusting the stiffness of said spring bracket.

6. In a roller skate having a sole plate, a spring suspension comprising, in combination, an elongated carrier having an intermediate portion and first and second arm portions extending from said intermediate portion angularly related to each other, each arm portion having an end region spaced from said intermediate portion, a roller axle mounted on said intermediate portion, rollers mounted on said axle, pivot means pivOtally connecting said first arm portion end region to the sole plate, a U-shaped deflectible spring bracket having a first leg connected to the sole plate and a second leg extending adjacent the end region of said second arm portion, elastomer buffer means interposed between and engaging said second leg and said end region of said second arm portion, and lost-motion fastening means extending between said second leg and said second arm portion maintaining engagement thereof with said elastomer buffer means and permitting compression of said elastomer buffer means.

7. In a roller skate as in claim 6 wherein said second leg and said end region of said second arm portion are substantially parallel to each other and are obliquely related to the sole plate.

8. In a roller skate as in claim 6 wherein said pivot means pivotally connecting said first arm portion end region to the sole plate comprises a socket defined in the sole plate receiving the end of said first arm permitting universal pivoting of said carrier with respect to the sole plate.

9. In a roller skate as in claim 6 wherein said fastening means comprises a draw screw, adjustment of said draw screw varying the precompression imposed on said elastomer buffer means.

10. In a roller skate as in claim 9 wherein said draw screw extends through said elastomer buffer means.

11. In a roller skate as in claim 6 wherein a pair of spaced parallel reinforcing ribs are longitudinally defined on the sole plate extending toward the spring suspension, said spring bracket first leg being interposed between said ribs and aligned on the sole plate thereby, and fastening means detachably connecting said spring bracket first leg to the sole plate.

12. In a roller skate having a sole plate, rollers and roller axles, a roller frame for the spring suspension of a roller axle mounted on said sole plate, said roller frame comprising an elongated carrier having arm portions and an intermediate portion, said roller axle mounted on said intermediate portion and one of said arm portions being pivotally connected to said sole plate, a U-shaped spring bracket having a first leg connected to said sole plate and a second leg connected to the other carrier arm portion and a spring insert incorporated into said spring bracket adjusting the stiffness of said spring bracket.
