Abstract

A device may include a base, a housing, a first shaft, and a second shaft, a first roller coupled to the first shaft, a second roller coupled to the second shaft, a first resistance that selectively impedes the rotation of the first roller and a second resistance that selectively impedes the rotation of the second roller, wherein the first shaft and second shaft are rotatable independently of each other, the first resistance is adjustable such that increasing the first resistance increases a force required to rotate the first roller and decreasing the first resistance decreases the force required to rotate the first roller, the second resistance is adjustable such that increasing the second resistance increases a force required to rotate the second roller and decreasing the second resistance decreases the force required to rotate the second roller, and the first resistance and the second resistance are independently adjustable.

Claims20

Dependent claims

An exercise and therapy device comprising:

a base;
a housing coupled to the base;
a first shaft extending from a first side of the housing;
a second shaft extending from a second side of the housing opposite the first side of the housing, the second shaft being coaxial with the first shaft;
a first roller coupled to the first shaft such that a rotation of the first roller causes an equal and simultaneous rotation of the first shaft;
a second roller coupled to the second shaft such that a rotation of the second roller causes an equal and simultaneous rotation of the second shaft;
a first resistance that selectively impedes the rotation of the first roller;
and
a second resistance that selectively impedes the rotation of the second roller;
wherein:
the first and second shafts are configured to each be rotated in either a clockwise or a counter-clockwise direction;
the first shaft is rotatable independently of the second shaft and the second shaft is rotatable independently of the first shaft;
the first resistance is adjustable such that increasing the first resistance increases a force required to rotate the first roller and decreasing the first resistance decreases the force required to rotate the first roller;
the second resistance is adjustable such that increasing the second resistance increases a force required to rotate the second roller and decreasing the second resistance decreases the force required to rotate the second roller;
and
the first resistance and the second resistance are independently adjustable.
