A plurality of ball transfer units is used together to form a reduced friction surface. The reduced friction surface lies on a base, and is particularly useful for carrying out a physical activity on, or applying force to, a body part on the surface so as to stretch the muscles and stretch and/or decompress the spine.

A vertical motion adjuster for a thermotherapy device includes a conveyance unit provided with a movable member configured to move along a mat, a support unit having a first side and a second side, the first side rotatably coupled to one side of the conveyance unit, and an elevation unit installed between the conveyance unit and the support unit and configured to adjust an angle of inclination of the support unit by raising or lowering the second side of the support unit such that the second side of the support unit is moved in the shape of an arc.

A cleansing device for mammalian skin includes a cleansing head having a plurality of elastomeric cleansing features extending away from a first surface of the cleansing head. The cleansing head is attached to a handle. The cleansing device includes an actuator coupled to a rotating drive shaft and adapted to apply oscillating movement to one or more cleansing head sections of the cleansing head at a frequency of about 5 Hz to 30 Hz.

A cleansing device for mammalian skin includes a cleansing head having a plurality of elastomeric cleansing features extending away from the first surface and having an aspect ratio of about 1:5 to 10:1. The cleansing head is attached to a handle adapted to apply oscillating movement to one or more cleansing head sections to provide a total displacement per oscillation of about 2 mm to 8 mm at a frequency of about 5 Hz to 30 Hz.

A massage chair includes a backrest, and two sets of massage arms assembled with the backrest and spaced apart from each other along a transversal axis of the backrest, each set including a first and a second massage arm that respectively have a first and a second contact member and are movable relative to each other. The method includes positioning the two sets of the massage arms such that at least the first contact members of the first massage arms contact a desired region of a user's body, actuating the two sets of the massage arms to perform a sequence of kneading pulses or a continuous kneading displacement from a wide state to a narrow state to apply a gripping action on the user's body, and stopping the two sets of the massage arms in the narrow state for a period of time to maintain the gripping action on the user's body.

A massage device includes a base, a drive unit, and a transmission unit. The drive unit is coupled to the base. The transmission unit is disposed at one side of the base. The drive unit includes a drive member to drive a rotary shaft for driving massage members. One end of the rotary shaft is provided with a unidirectional bearing and a first bevel gear. The unidirectional bearing is able to control the rotation of the first bevel gear. The transmission unit includes two positioning blocks and a worm shaft connected between the two positioning blocks. The worm shaft is provided with a second bevel gear and a movable member thereon. The first bevel gear meshes with the second bevel gear. When the first bevel gear is rotated, the second bevel gear is driven to link other parts so that the drive unit can slide on the base.

The invention relates to an exoskeleton including: a foot structure; a lower leg structure; a mechanical knee link having a pivot axis; and a mechanical ankle link connecting the foot structure to the lower leg structure and including a first pivot connection having a first pivot axis that is substantially parallel to the pivot axis of the mechanical knee link, and a second pivot connection having a second pivot axis that is perpendicular to the first pivot axis and forms an angle of between 30 and 60 with the support plane when the exoskeleton is upright and at rest.

A beauty device includes a handle, an inner lid, a pair of support shafts, a pair of rotation bodies, a water stop portion, and an outer lid. The handle is formed with a housing portion. The inner lid is mounted to the handle to seal the housing portion. The pair of support shafts is extended from one end of the handle. The pair of rotation bodies is rotatably supported around the support shafts. The water stop portion is intervened between the housing portion and the inner lid to contact with a peripheral edge of an opening of the housing portion. The outer lid closes the opening while covering the inner lid such that the outer lid is fitted in the housing portion in a state where a part of an outer circumference surface of the outer lid facing an inner circumference surface of the opening is visible from an outside.

The present invention relates to a functional chair with massage balls that is capable of allowing the massage balls to protrude outwardly therefrom through the manipulation of armrests to massage a user's muscles around the back and spine, thereby permitting the user's fatigue due to long sitting hours to be relieved. The functional chair includes: a seat; a seat support adapted to support the seat; a backrest having a plurality of massage holes formed penetratedly thereon; a backrest support having an inside partition extended from edges of an open surface; a pair of massage parts having the massage balls protruding from the massage holes or inserted into the massage holes; a pair of armrests adapted to rotate the massage parts; a seat connector adapted to fix the seat and the backrest thereto; and a stopper adapted to control rotation of the massage parts.

A massage device for a seat includes a pressing portion configured to expand to press a seat occupant seated on the seat, an adjustment portion configured to adjust a position of the pressing portion between the seat occupant and the seat, a deformation detector configured to detect deformation of the seat caused by expansion of the pressing portion, and a controller configured to control the adjustment portion based on a detection result of the deformation detector.
