Claims
- 1. Skate braking apparatus comprising:
- a) a support frame including a plurality of wheels aligned seriatim between sidewalls of the support frame and along a longitudinal axis of the support frame; and
- (b) a skid pad having a terrain contacting brake surface, wherein said skid pad is mounted to said support frame and to a pivot having a pivot axis coaxial to the longitudinal axis such that the skid pad can rotate about the pivot to maintain said brake surface parallel to the terrain and normal to a plumb axis to the terrain and through said pivot and independent of a cant angle of said frame from the plumb axis, whereby the brake surface uniformly engages the terrain without incurring uneven wear at the brake surface.
- 2. Apparatus as set forth in claim 1 including stop means for limiting rotation of said skid pad relative to the cant angle of said frame.
- 3. Apparatus as set forth in claim 1 including:
- (a) a bracket mounted to said frame to a first pivot having a pivot axis transverse to the longitudinal axis of the frame and including a second pivot having a pivot axis coaxial to the longitudinal axis of said frame;
- (b) means for retaining the bracket to the frame; and
- (c) wherein said skid pad is mounted to said first axis to longitudinally pivot the skid pad and to the second axis to laterally pivot the skid pad to accommodate side-to-side canting of said frame.
- 4. Apparatus as set forth in claim 3 wherein a resilient member projects from said skid pad to contact surfaces of said bracket to bias said skid pad to an equilibrium position centered to said frame.
- 5. Apparatus as set forth in claim 4 wherein said resilient member projects from said skid pad and mounts within a cavity of said bracket, and wherein said cavity includes tapered walls which bias said skid pad to an equilibrium position centered to said frame.
- 6. Apparatus as set forth in claim 4 wherein first and second stop surfaces of said bracket limit lateral rotation of said skid pad.
- 7. Apparatus as set forth in claim 4 wherein said skid pad includes a cap piece and a ground pad secured to said cap piece, and wherein surfaces of said bracket contact said cap piece to limit rotation of said skid pad.
- 8. Apparatus as set forth in claim 4 wherein said skid pad comprises a cap piece, a ground pad, and fastener means for retaining said ground pad to said cap piece, and wherein said second pivot comprises an axle which supports said skid pad to said bracket.
- 9. Skate braking apparatus comprising:
- (a) a support frame including a plurality of wheels aligned seriatim between sidewalls of the support frame and along a longitudinal axis of the support frame;
- (b) a bracket mounted to said frame at a first pivot having a pivot axis transverse to the longitudinal axis of the frame and including an axle mounted coaxial to the longitudinal axis of said frame; and
- (c) a skid pad mounted to said bracket having a brake surface and a resilient member which projects to contact surfaces of said bracket to bias said skid pad to an equilibrium position, and wherein said skid pad is mounted to a pivot having a pivot axis coaxial to the longitudinal axis to rotate and maintain said brake surface parallel to the terrain and normal to a plumb axis to the terrain through said axle and independent of a cant angle of said frame from the plumb axis., whereby the brake surface uniformly engages the terrain without incurring uneven wear at the brake surface.
- 10. Apparatus as set forth in claim 9 wherein first and second stop surfaces of said bracket limit lateral rotation of said skid pad.
- 11. Apparatus as set forth in claim 10 wherein said resilient member which projects from said skid pad mounts within a cavity of said bracket.
- 12. Apparatus as set forth in claim 9 wherein said skid pad includes a cap piece having plurality of projecting surfaces which are integrally molded into said skid pad.
- 13. Skate braking apparatus comprising:
- (a) a support frame including a plurality of wheels aligned seriatim between sidewalls of the support frame and along a longitudinal axis of the support frame;
- (b) a skid pad having a brake surface; and a support member fastened to said frame, an axle mounted coaxial to the longitudinal axis of said frame to support said skid pad to said support member to laterally pivot and maintain said brake surface parallel to the terrain and independent of a cant angle of said frame from a plumb axis to the terrain, whereby the brake surface uniformly engages the terrain without incurring uneven wear at the brake surface.
- 14. Skate braking apparatus comprising:
- a) a support frame including a plurality of wheels aligned seriatim between sidewalls of the support frame and along a longitudinal axis of the support frame; and
- (b) a skid pad having a terrain contacting brake surface, wherein said skid pad is mounted to said support frame at an axle having a pivot axis coaxial to the longitudinal axis to laterally pivot such that the skid pad can rotate about the axle to maintain said brake surface parallel to the terrain and normal to a plumb axis to the terrain through said pivot and independent of a cant angle of said frame from the plumb axis, whereby the brake surface uniformly engages the terrain without incurring uneven wear over the brake surface.
- 15. Skate braking apparatus comprising:
- (a) a support frame including a plurality of wheels aligned seriatim between the sidewalls of the support frame and along a longitudinal axis of the support frame;
- (b) a bracket mounted to said frame at a first pivot having a pivot axis transverse to the longitudinal axis of the frame and including an axle mounted coaxial to the longitudinal axis of said frame; and
- (c) a skid pad mounted to said bracket having a brake surface and a resilient member which projects from said skid pad to mount within a cavity of said bracket to bias said skid pad to an equilibrium position, and wherein said skid pad is mounted to a pivot to rotate and maintain said brake surface parallel to the terrain and normal to a plumb axis to the terrain through said axle and independent of a cant angle of said frame from the plumb axis, whereby the brake surface uniformly engages the terrain without incurring uneven wear at the brake surface.
