Abstract: A muscle exerciser having a first pulley mounted on a motor shaft of a motor, a second pulley mounted on a pulley shaft and connected to the first pulley through a transmission belt, two transmission wheels respectively connected two ends of the pulley shaft, two transmission links connected to the wheels, and two sliding seats connected to the links. The transmission wheels are respectively connected to the transmission links oppositely such that the two sliding seats are moved close to or away from each other along sliding tracks when the wheels are rotated. Thus, the quick sliding of the sliders strengthens the muscle of the hands/feet placed on the sliding seats.

Abstract: A dual use massage chair has inflatable and deflatable air bags and bladders in a chair back to provide a massage function and serve as a comfortable chair. The main structure thereof includes the air bags disposed at two sides of a seat and in a front cover, and the bladders and recovering springs disposed between a massage mechanism and a back frame. Inflating the air bags and the bladders respectively or simultaneously can form a separating space for separating the massage mechanism from a back of a human body and thus to form a comfortable sofa chair. Also, the bladders and the air bags may be deflated to recover the use of the normal massage chair. Thus, the utilities of the comfortable chair and the typical massage chair can be achieved.

Abstract: A lower leg massage device includes a rotatable shaft having two actuating pins, two actuating devices solidly secured on the shaft, and two rotatable actuating devices rotatably attached onto the shaft and each having two opposite seats for selectively engaging with the actuator pins of the shaft. Four massage members are attached onto and to be vibrated by the actuating devices. The actuator pins may selectively engage with the one of the seats to rotate the rotatable actuating devices in one direction, and may engage with the other seat to rotate the rotatable actuating devices in the other direction, and to allow the massage members to be arranged either opposite to or parallel to each other.

Abstract: A massaging foot bath includes a main body, an air guide cushion, a pneumatic air pump, and an air pipe. The air guide cushion has a surface formed with a plurality of air holes each connected to the inside of the air guide cushion and the receiving chamber of the main body to deliver the air contained in the inside of the air guide cushion into the receiving chamber. Thus, the foot bath is operated in a pneumatic manner to produce pressurized air bubbles in the water contained in the receiving chamber to touch and massage the feet of a user, thereby providing a massaging effect to the user's feet.

Abstract: A chair includes a seat rotatably attached to a base with a pivot axle and coupled to the base with an actuator, to adjust the seat relative to the base. A seat back is rotatably attached to the seat and coupled to the seat with another actuator, to adjust the seat back relative to the seat. A foot support is rotatably attached to the seat and coupled to the seat with a further actuator, to adjust the foot support relative to the seat. The seat is adjustable relative to the base, the seat back is adjustable relative to the seat, and the foot support is adjustable relative to the seat with different actuators. The foot support may include a foot pedal slidably coupled to a plate with another actuator.

Abstract: A chair support device includes a frame having a rear portion pivotally secured to a front portion of a base and movable relative to the base between a downward folding position and a working position. A foot pedal is slidably supported on the frame and movable forwardly and rearwardly relative to the frame. A rotating device may rotate the frame between the downward folding position and the working position, to move the foot pedal forwardly relative to the frame when the frame is rotated toward the working position, in order to comfortably support the feet of the users.

Abstract: A massaging device includes a massaging member having a number of upper rods for engaging with and for massaging users, and a number of reinforcing ribs for reinforcing purposes. A peripheral handle device has two hand grips, a motor is secured on the handle device and coupled to an eccentric member for rotating the eccentric member to generate a vibration. A casing may be secured to the motor with one or more cushioning members. One or more further massaging members may be detachably secured onto the casing and each has a tip, or a cap for massaging different portions of the users.

Abstract: A massage device includes a housing, a follower received in the housing and having a stem extended outward of the housing, and one or more massage members selectively and changeably secured to the stem for massaging the users. A shaft is rotatably received in the follower, and a motor has a spindle secured to the shaft at an off-center bore for moving and vibrating the follower in a reciprocating action. One or more infrared generating devices may further be attached to the housing for facilitating the blood circulation of the users.

Abstract: A chair includes a base having two rear posts, two pairs of levers having rear ends pivotally secured to the posts and having two lever members located above the other two lever members. A seat has two front legs extended downward and pivotally secured to the front ends of the levers with pivot axles for allowing the seat to move up and down relative to the base. An actuating device is disposed on the base and coupled to the front end of the seat for elevating the seat relative to the base and for rotating the legs of the seat and for tilting the seat relative to the base.

Abstract: A pressurized air supplying device is coupled to the DC electric power of the vehicle for supplying a pressurized air to a massage device of the vehicle. The pressurizing device includes two membranes secured to two sides of a housing and each having a peripheral portion secured to the housing with a casing. A follower is secured between the membranes. A motor is secured to the housing and has an eccentric axle slidably engaged through the follower to actuate the follower and the membranes to pressurize the air and to generate a pressurized air to the massage device.

Abstract: A bed includes a number of holes for receiving a number of pneumatic actuating devices, such as the air bag type or the bellows type pneumatic actuating devices. An air pump supplies a pressurized air to the pneumatic actuating devices via a number of air valves to actuate the pneumatic actuating devices to act on the users. An air reservoir is disposed between the air pump and the air valves for storing the pressurized air. One or more seats are disposed on the bed and each has a pneumatic actuating device for acting on the side portion of the user.

Abstract: A chair includes a base and a seat each having two side tracks and a front track. Three pairs of pivotal bars have upper ends coupled to the tracks of the seat and have lower ends coupled to the tracks of the base. The bars may expand and fold when the seat moves up and down relative to the base. A tube is extended in the base, the seat includes a downward extending rod slidably engaging in the tube and threaded with a bolt. A motor is coupled to the bolt for driving the bolt and for moving the seat up and down relative to the base to adjust the height of the seat relative to the base.

Abstract: A massage device includes a shaft and an axle rotatably engaged in a housing and aligned with each other. The shaft has a bevel gear and the axle has a worm gear. Two motors are coupled to the shaft and the axle for driving the shaft and the axle individually. A rod and a pole are rotatably engaged in the housing and each has a bevel gear and a worm gear for engaging with that of the shaft and the axle. Two massage members are coupled to the rod and the pole for allowing the massage members to be actuated individually by the motors.
