ABSTRACT:
FIELD OF THE INVENTION
This invention relates to roller skates as well as ice skates, and more particularly to skates used in speed contests.
BACKGROUND OF THE INVENTION
In the course of a skating speed contest, it is advantageous at times to increase the angular position of the feet in relationship to the skating surface by raising the heel. When using the prior art skates the above maneuver reduces the amount of contact between the skate and the skating surface. This in turn may reduce traction and the amount of driving force that the skater can apply to the skates.
SUMMARY OF THE INVENTION
The primary and secondary objects of the invention are to provide a new type of skates in which the angular relationship between the foot-receiving upper part of the skate and the part in contact with the skating surface, whether the latter is a roller assembly or a blade, can be varied at will or locked into a standard position.
These and other valuable objects are achieved by a skate in which the fore-foot section of the boot or foot rest is hinged to the ground-contacting assembly, and the foot is constantly urged towards a common, traditional flat position by a spring whose bias can easily be overcome by the skater to raise the heel as may be more advantageous under certain conditions. The foot-holding and ground-contacting assemblies can also be locked.
