Abstract
A skate having a height adjustment mechanism which allows the skater to shift his or her center of gravity by varying the skate's angle of inclination relative to the skating surface, the height adjustment mechanism having a screw for moving a wedge with an inclined surface along a surface of the skate's support assembly, in order to raise or lower the skate's heel.
Claims14
A skate comprising:
- (a) a boot having a toe-end, a heel-end which is positioned along a longitudinal axis from said toe-end, and a sole;
- (b) a skate assembly having at least one ground-contacting element;
- (c) a support element for supporting one end of said boot on said skate assembly, said support element pivotally connecting said one end of said boot to said skate assembly to permit longitudinal pivoting between said toe-end and said heel-end of said boot;
- (d) a height-adjustment and support assembly for adjustably connecting the other end of said boot to said skate assembly and for adjusting the height of said other end of said boot relative to said skate assembly, said height-adjustment and support assembly comprising a movable element and a stationary element, each element having a surface that is inclined from the longitudinal axis of said boot;
- (e) means for holding said inclined surfaces of said movable and stationary elements in juxtaposition while permitting said inclined surface of said movable element to move linearly relative to said stationary element, so as to adjust the height of said other end of said boot relative to said skate assembly;
- and
- (f) adjustment means connected to said movable element for effectuating linear movement of said movable element relative to said stationary element, so as to adjust the height of said other end of said boot relative to said skate assembly.

A skate comprising:
- (a) a skate assembly having a forward end and a rearward end positioned along a longitudinal axis from said forward end, said skate assembly including at least one ground-contacting element;
- (b) a boot supported above said skate assembly and having a toe-end, a heel-end longitudinally opposite said toe-end, and a sole;
- (c) a support element for supporting said toe-end of said boot above said forward end of said skate assembly, said support element having a first end rigidly connected to said toe-end of said boot, and a second end pivotally connected to said forward end of said skate assembly to permit longitudinal pivoting between said boot and said skate assembly;
- (d) a height-adjustment and support assembly for supporting the heel-end of said boot above said rearward end of said skate assembly, said height-adjustment and support assembly including a carriage yoke pivotally connected to said skate assembly, and further including a wedge-shaped movable element having an inclined upper surface, said movable element having a flat lower surface which is linearly slidable along said carriage yoke for raising and lowering said heel-end of said boot relative to said skate assembly;
- and
- (e) threaded adjustment means for causing said movable element to slide linearly along said carriage yoke.
