Abstract
Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks formed parallel to each other along first axis, a second track disposed on the pair of first tracks, and moving along the first axis, and formed along second axis, a hand holder disposed on the second track, and moving along the second track, and on which at least one of hand and arm of a user is held, a stopper for a track disposed on the pair of first tracks for limiting a movement range of the second track, and a stopper for a holder disposed on the second track for limiting a movement range of the second pair of first tracks, wherein the first axis and the second axis are disposed with an inclination.
Core Innovation
The invention relates to a rehabilitation training apparatus including a track and a hand holder movably disposed on the track and configured to hold a hand and an arm of a user. The hand holder comprises a support bracket that moves along the track and includes a long-hole-shaped slot penetrating along a longitudinal direction of the support bracket, and a coupler that movably couples a holder body along the slot. A holder body positioned above a first end portion of the support bracket is configured to hold the arm of the user, while a handle supported by a second end portion is configured to be gripped by the hand of the user.
The apparatus supports controlling an exercise range by limiting movement ranges using a track stopper and a holder stopper. The limiting is implemented through selectively positionable stopper pins/clips and mounting grooves, and the rehabilitation training apparatus provides adjustable or retractable track lengths for setting the exercise range for user training with a hand holder that moves along the track.
The apparatus further provides an X-Y coordinate board formed by intersecting light emitting elements and light receiving elements, with light paths whose intersection defines X-Y coordinates on the board. A pointer on the hand holder includes a pointer tip that interrupts the light paths to indicate the hand holder location on the board, and coordinate data can be transmitted via a communication module. The system supports wrist/shoulder joint rehabilitation and includes an option to incline the first axis and the second axis to increase exercise load.
Claims Coverage
The independent claims cover a rehabilitation training apparatus with a movable hand holder on a track, a support bracket having a long-hole-shaped slot and a coupler, movement-range limiting with stoppers, an optical X-Y coordinate indication scheme, and an arrangement with parallel first tracks and an inclined second track. The claim set includes 5 inventive features.
Hand holder movably coupled via long-hole-shaped slot
A track and a hand holder movably disposed on the track and configured to hold a hand and an arm of a user, wherein the hand holder comprises a support bracket configured to move along the track, a holder body positioned above the first end portion spaced apart by a first distance and configured to hold the arm of the user, a long-hole-shaped slot formed on the first end portion and penetrating along a longitudinal direction of the first end portion, a handle supported by the second end portion and configured to be gripped by the hand of the user, and a coupler that movably couples the holder body along the slot.
Optical X-Y coordinate board using intersecting light paths
A rehabilitation training apparatus further including light emitting elements and light receiving elements, wherein intersecting light paths form X-Y axis coordinates on a board.
Pointer indicates hand holder position by interrupting light paths
A rehabilitation training apparatus indicating the hand holder's location on the board using a pointer that blocks light paths through a pointer tip to operate on X-Y axis coordinates.
Track and holder movement limiting using stoppers
A rehabilitation training apparatus further includes a stopper that limits movement of the hand holder.
Parallel first tracks and inclined second track with hand holder on second track
A rehabilitation training apparatus using a pair of first tracks disposed along a first axis and a second track moving along a second axis at an inclination, where a hand holder on the second track holds the user's hand/arm and moves with the second track.
Overall, the claims emphasize a movable hand holder guided by a support bracket with a long-hole-shaped slot and coupler, movement-range limitation using stoppers, and an X-Y coordinate indication scheme using intersecting light paths on a board and a pointer tip on the hand holder to indicate its location.
Stated Advantages
Allows convenient exercise-range setting by limiting movement ranges and providing adjustable/retractable track lengths.
Supports wrist/shoulder joint rehabilitation using a coordinate-indicating board and pointer-based location indication.
An option to incline the board/axes increases exercise load.
Documented Applications
Wrist and shoulder joint rehabilitation training supported by the rehabilitation training apparatus with hand/arm holding and X-Y coordinate indication.
