Abstract

Disclosed is a rehabilitation training apparatus including a pair of first tracks that are arranged in parallel at an interval, a second track that is perpendicular to the pair of first tracks and is movably connected to the pair of first tracks, a hand holder that is movably provided in the second track and on which a hand of the user is held, a holder driving unit that reciprocally moves the hand holder along the second track, and a track driving unit that reciprocally moves the second track along the pair of first tracks.

Core Innovation

The rehabilitation training apparatus uses a pair of first tracks arranged in parallel at an interval and a second track that is perpendicular to the pair of first tracks and is movably connected to the pair of first tracks. A hand holder is movably provided in the second track and is configured so that a hand of a user is adapted to be held. A holder driving unit reciprocally moves the hand holder along the second track while a track driving unit reciprocally moves the second track along the pair of first tracks.

The holder driving unit includes a holder rack having a plurality of gear teeth along a lengthwise direction of the second track, a holder pinion engaged with the gear teeth and configured to be rotated, and a holder motor that generates a rotational force and transmits the generated force to the holder pinion. A track driving unit includes a track motor and is configured to move the second track along the pair of first tracks, with a mechanical drivetrain arrangement using gear teeth and a pinion engaged to a rack. The control unit controls both the track motor and the holder motor.

The control unit controls the hand holder to move in a curved manner by controlling the track motor and the holder motor to have different rotation speeds from each other. The movement is described as a predetermined path and as motion on a plane defined by the first tracks and the second track. The apparatus further supports automatic motion patterns by using a pattern recognizing unit and coordinate data associated with a printing pattern and/or pre-stored or externally received movement pattern coordinate data and movement speed data.

A memory and/or a communication module stores or receives plane coordinate data and movement speed data for a movement pattern, and the pattern recognizing unit recognizes coordinate data for a printing pattern on the plane. The control unit drives the holder driving unit and the track driving unit based on the recognized printing-pattern coordinate data and/or the movement pattern coordinate data and movement speed data.

Claims Coverage

The document includes two independent claims directed to a rehabilitation training apparatus with a two-axis track arrangement and coordinated motion control. The inventive features include the parallel/perpendicular track geometry, the rack-and-pinion based holder and track driving units, and control of curved motion by coordinating motor rotation speeds, with additional coverage for coordinate-data-based automatic motion.

Across the independent claims, the coverage centers on a rehabilitation training apparatus using parallel first tracks and a perpendicular, movably connected second track to support a hand holder, with rack-and-pinion holder and track driving units. Curved motion is produced by a control unit coordinating the track motor and holder motor with different rotation speeds. The claim set further covers coordinate-data-based automatic operation using a printing pattern coordinate recognition unit and stored or received plane coordinate data and movement speed data.
