Abstract: A medical robot cover covers an external surface of a medical robot including: a main unit that stands on a base; and an arm member attached to one end of the main unit in a swingable or extensible manner. The medical robot cover includes: an attaching portion to be wound around at least one of the main unit and the arm member, on an inner circumferential surface of the cover facing the external surface of the medical robot. Therefore, the medical robot cover can be easily placed on the medical robot. Further, the medical robot cover can be restricted from being damaged due to extension or swinging of the arm member, and can be restricted from inhibiting the action of the arm member.

Abstract: A balance practicing machine that provides effective balancing practice through the compound movement of an adjustable seat that comfortably accommodates various body types. The balance practicing machine is equipped with a saddle-shaped seat upon which a user sits, a drive unit that imparts a swinging motion to the seat, expandable and contractible elements on the surface of the seat, and a mechanism to expand and contract the expandable and contractible elements.

Abstract: A wedge-shaped tilt provider is attached in contact with the bottom surface of a seat and the upper surface of a seat connection member of a rocking mechanism to set the seat to an initial inclined position relative to a reference position. By setting the seat to a forwardly inclined position from a horizontal position where the seated surface of the seat is set horizontal, the user straddling the seat can increase the amount of muscle activity of his or her rectus muscle of abdomen, or abdominal muscle. Further, by setting the seat to a rearwardly inclined position, the user straddling the seat can increase the amount of muscle activity of his or her back muscle such as paraspinal muscle.

Abstract: A chair-type massage machine with a seat, a backrest and an armrest comprises an upper member which is disposed above and in spaced-apart relation to the armrest with a distance allowing a hand and/or arm to be inserted therebetween, to extend in the same direction as that of the armrest. A lower air bag adapted to be inflated/deflated by an air pressure is attached onto a top surface of the armrest. First and second upper air bags adapted to be inflated/deflated by an air pressure are attached onto a bottom surface of the upper member to form a line along a longitudinal direction of the upper member. The total surface area of the upper air bags and the total volume of the upper air bags in their inflated state are set to be less than the surface area of the lower air bag and the volume of the lower air bag in its inflated state, respectively.

Abstract: A balance practicing machine that offers simplified control, reduced cost, and a compact drive assembly that reduces the space requirement for the machine. The machine includes an output shaft from one side of a power source to impart three movements to the seat in the form of a repetitive linear motion in the longitudinal direction, a repetitive pivoting motion around a longitudinal shaft, and a repetitive pivoting motion around transverse shafts. A seat base is connected to an active frame, through connector links, so as to provide swinging movement of the seat base around transverse shafts. The active frame is connected to a base member so as to allow the repetitive pivoting movement of the active frame around a longitudinal shaft.

Abstract: A balance training apparatus, which is preferably used for training a body balance function and a locomotive function of a user, and for rehabilitation for lumbago prevention, is provided. This apparatus has a seat for the user and a driving unit for driving the seat. The driving unit comprises a drive source and a power transmission unit for converting an output of the drive source into a horse-riding motion, which is a combination of a rectilinear reciprocating motion in a forward and backward direction (X) of the seat, a first pivotal reciprocating motion (?y) about an axis extending in a horizontal direction substantially perpendicular to the forward and backward direction, and a second pivotal reciprocating motion (?x) about an axis extending in the forward and backward direction, and transferring the horse-riding motion to the seat.
