Abstract

Supination and pronation of an ankle joint during a lower limb exercise is achieved. A foot-pedaling exercise equipment as a lower limb exercise equipment is a lower limb exercise equipment that enables a lower limb exercise to be performed using a pair of pedal units. Each of pedal units includes: a step part on which a corresponding foot part can be put; a base part; and a joint part that is provided between the step part and the base part and couples the step part to the base part in such a way that the step part can do a pitch turn, a roll turn, and a yaw turn with respect to the base part.

First claim

What is claimed is:

1 . A lower limb exercise equipment that enables a lower limb exercise to be performed using a pair of pedal units, each of the pedal units comprising:
a step part on which a corresponding foot part can be put; a base part; and a joint part that is provided between the step part and the base part and couples the step part to the base part in such a way that the step part can do a pitch turn, a roll turn, and a yaw turn with respect to the base part.

2 . The lower limb exercise equipment according to claim 1 , wherein the joint part of each of the pedal units comprises a roll joint part for enabling a roll turn to be conducted, a pitch joint part for enabling a pitch turn to be conducted, and a yaw joint part for enabling a yaw turn to be conducted.

3 . The lower limb exercise equipment according to claim 2 , wherein the joint part of each of the pedal units comprises, in an order from the step part to the base part, the roll joint part, the pitch joint part, and the yaw joint part.

4 . A pedal unit that can be attached to and detached from a binding pedal, the pedal unit comprising:
a step part on which a corresponding foot part can be put; a base part comprising a cleat that snap-fits with the binding pedal; and a joint part that is provided between the step part and the base part and couples the step part to the base part in such a way that the step part can do a roll turn and a yaw turn with respect to the base part.
