Abstract

An in-line skate having a first pair of rollers rotatably mounted to a first mount and a second pair of rollers rotatably mounted to a second mount. Each mount is pivotally mounted to the skate about a separate pivot axis allowing a single roller to move upwardly or downwardly relative to the surface supporting the rollers while the remaining rollers remain in contact with the supporting surface.

Claims

1. A roller assembly to mount to a roller skate having a direction of travel along a supporting surface comprising:

a first roller frame mountable to a roller skate;

a first plurality of skate rollers rotatably mounted to said frame about a first set of parallel rotation axes extending perpendicular to a direction of travel of the roller skate with said rollers arranged in a single row extending in said direction of travel, and,

a first mount to pivotally mount said roller frame to the skate about a single first pivot axis parallel to said rotation axes allowing one of said rollers to leave said supporting surface while the remaining rollers on said roller frame remain in contact with said supporting surface and support the roller skate thereon.

2. The roller assembly of claim 1 wherein:

said first roller frame includes first and second walls extending perpendicular to said axes and further includes a third wall joining said first and second walls together, said first arid second walls are spaced apart with said rollers positioned therebetween.

3. The roller assembly of claim 1 wherein,

said rollers include a first roller and a second roller with said mount located therebetween positioning said pivot axis between said first roller and said second roller.

4. The roller assembly of claim 1 and further comprising:

a second roller frame mountable to the roller skate said second roller frame is located aft of said first roller frame along the direction of travel of the roller skate;

a second plurality of skate rollers rotatably mounted to said second frame about a second set of parallel rotation axes perpendicular to the direction of travel of the roller skate; and

,

a second mount to pivotally mount said second roller frame to the skate about a single second pivot axis parallel to said first set and second set of rotation axes and parallel to and aft of said first pivot axis allowing one of said second plurality of rollers to leave said supporting surface while other rollers of said first plurality of rollers and said second plurality of rollers contact said supporting surface and support the roller skate thereon.

5. The roller assembly of claim 4 wherein:

said first roller frame includes first and second walls extending perpendicular to said axes and further includes a third wall joining said first and second walls together, said first and second walls are spaced apart with said rollers positioned therebetween; and

,

said second roller frame includes fourth and fifth walls extending perpendicular to said second set of axes and further includes a sixth wall joining said fourth aid fifth walls together, said fourth and fifth walls are spaced apart with said second plurality of skate rollers positioned therebetween.

6. The roller assembly of claim 5 wherein:

said first plurality of skate rollers include a first roller and a second roller with said first mount located therebetween positioning said first pivot axis between said first roller and said second roller, said second plurality of rollers include a third roller and a fourth roller with said second mount located therebetween positioning said second pivot axis between said third roller and said fourth roller.

7. The roller assembly of claim 6 wherein:

said third wall and said sixth wall form stops limiting pivotal motion respectively of said first roller frame and said second roller frame.

8. An in-line roller skate movable in a direction of travel on a surface supporting the skate comprising:

a foot support;

a first roller mounting bracket pivotally mounted to said foot support and having a single first pivot axis perpendicular to a direction of travel of a roller skate and parallel to a surface supporting the roller skates;

a first roller and a second roller rotatably mounted to said first roller mounting bracket being arranged in a row having a longitudinally extending axis perpendicular to said first pivot axis and further having a first rotation axis and a second rotation axis both parallel to said first pivot axis;

a second roller mounting bracket pivotally mounted to said foot support and having a single second pivot axis parallel to said first pivot axis; and

,

a third roller and a fourth roller rotatably mounted to said second roller mounting bracket and having a third rotation axis and a fourth rotation axis both parallel to said second pivot axis, said first mounting bracket and said second mounting bracket having respectively said first pivot axis and said second pivot axis arranged perpendicular to the direction of travel of the skate to allow a single roller to leave said surface white all of the remaining rollers may remain in contact with said surface.

9. The roller skate of claim 8 wherein:

said first rotation axis and said second rotation axis are located closer to said foot support than said first pivot axis stabilizing said foot support as said first roller bracket mounting bracket pivots therein.

10. The roller skate of claim 9 wherein:

said third rotation axis and said fourth rotation axis are located closer to said foot support than said second pivot axis stabilizing said foot support as said second roller bracket mounting bracket pivots thereon.

11. The roller skate of claim 10 wherein:

said first roller mounting bracket includes a first pair of parallel walls extending perpendicular to said first pivot axis, said first roller and said second roller each have axles rotatably mounted to and extending between said first pair of parallel walls, said first roller mounting bracket includes an extension with a proximal end mounted to said foot support and a pivot joint located between said first pair of parallel walls and located between said axles.

12. The roller skate of claim 11 and further comprising:

said first roller mounting bracket includes a first stop contacting said extension limiting pivotal action of said first roller mounting bracket.

13. A roller assembly to pivotally mount to a roller skate comprising:

a first roller frame pivotally mountable to a roller skate;

a first plurality of skate rollers rotatably mounted to said frame about a first set of parallel rotation axes with said rollers aligned in a row extending perpendicular to said axes; and

,

a first mount to pivotally mount said roller frame to the skate about a first pivot axis parallel to said rotation axes allowing one of said rollers to pivot, said rollers pivot about the same first pivot axis allowing the skate to remain level although one of said rollers pivot.

14. The roller assembly of claim 13 wherein:

said roller frame includes first and second walls extending perpendicular to said axes and further includes a third wall joining said first and second walls together, said first and second walls are spaced apart with said rollers positioned therebetween.

15. The roller assembly of claim 13 and further comprising:

second roller frame pivotally mountable to a roller skate aft of said first roller frame;

a second plurality of skate rollers located aft of said first plurality of skate rollers and rotatably mounted to said second frame about a second set of parallel rotation axes; and

,

a second mount to pivotally mount said second roller frame to the skate about a second pivot axis parallel to said second set of parallel rotation axes, said second plurality of skate rollers pivot about the same second pivot axis.

16. The roller assembly of claim 15 wherein:

said first roller frame and said second roller frame include stop surfaces to contact respectively said first mount and said second mount and limit pivotal motion of said first plurality of skate rollers and said second plurality of skate rollers.
