Abstract
A knee joint stimulation device that can effectively stimulate a knee joint is composed of a base, a frame provided upright on the base, a center shaft provided at an upper part of the frame, a crank connecting a motor and the center shaft and driven by rotation of the motor, a swing arm hanging down perpendicularly from the center shaft, and a support plate unit provided at a lower end of the swing arm and allowing a user in a sitting position to put his/her sole thereon. With the user putting the sole on the support plate unit, the length of the swing arm is adjusted such that a pivot point of a knee joint of the user is aligned with the center shaft.
Claims12
A knee joint stimulation device comprising:
- a base;
- a frame provided upright on the base;
- a center shaft provided at an upper part of the frame;
- a crank connecting a motor and the center shaft and driven by rotation of the motor, the center shaft being pivotable via the crank;
- a swing arm hanging down perpendicularly from the center shaft, a length of the swing arm being adjustable;
- and
- a support plate unit provided at a lower end of the swing arm and allowing a user in a sitting position to put a sole of the user thereon,
- wherein, with the user putting the sole on the support plate unit, the length of the swing arm is adjusted such that a pivot point of a knee joint of the user is aligned with the center shaft,
- wherein, by swinging movement of the swing arm, the support plate unit can move the sole resting thereon in a flexion direction or an extension direction about the knee joint,
- wherein the support plate unit is pivotable about a support shaft that horizontally extends from the lower end of the swing arm, and
- wherein, even when the sole resting on the support plate unit moves in a flexion direction or an extension direction about the knee joint and thereby an ankle joint is caused to move in a plantarflexion direction and a dorsiflexion direction, the support plate unit can pivotally follow the movement of the sole.
A knee joint stimulation device comprising:
- a base;
- a frame provided upright on the base;
- a center shaft provided at an upper part of the frame;
- a crank connecting a motor and the center shaft and driven by rotation of the motor, the center shaft being pivotable via the crank;
- a pair of swing arms hanging down perpendicularly from both sides of the center shaft across the motor, a length of the swing arms being adjustable;
- and
- a pair of support plate units provided at lower ends of the pair of swing arms and allowing a user in a sitting position to put soles of the user thereon,
- wherein, with the user putting the soles on the support plate units, the length of the swing arms is adjusted such that pivot points of knee joints of the user are aligned with the center shaft,
- wherein, by swinging movement of the swing arms, the support plate units can move the soles resting thereon in a flexion direction or an extension direction about the knee joints,
- wherein the support plate units are pivotable about support shafts that horizontally extend from the lower ends of the swing arms, and
- wherein, even when the soles resting on the support plate units move in a flexion direction or an extension direction about the knee joints and thereby ankle joints are caused to move in a plantarflexion direction and a dorsiflexion direction, the support plate units can pivotally follow the movement of the soles.
