Abstract: A massage chair may include a base unit, a seat unit, a reciprocating unit and a massage unit. The base unit comprises two frames formed at each of two lateral sides of the base unit. Each of two lateral sides of the seat unit has a rear guiding rail and a lower guiding rail, which are connected to each other with a defined angle. A rear frame connected with two outer laterals of the rear guiding rails protrudes from a rear portion of the seat unit. The reciprocating unit comprises a base secured under the rear frame, and a motor is secured on the base. Moreover, a threaded rod vertically protrudes from a top portion of the base, and is driven by the motor to spin relative to a surface of the base.

Abstract: A massage apparatus having a power source that can be a motor producing forward and reverse movement, and an active gear attached to a protruding axis from the power source. The active gear engages with a passive gear on a horizontal transmission stick to transmit the power, and the power source can drive a vertical transmission stick through a steering gear group, so that the horizontal transmission stick and vertical transmission stick can generate simultaneous forward and reverse movement. Also, a transmission gear is disposed on the horizontal transmission stick, and a conjugated gear is disposed on a one-way bearing of a horizontal threaded rod that is parallel to the horizontal transmission stick. Furthermore, a massaging unit is conjugated with pairs of horizontal transmission sticks, horizontal threaded rods, vertical transmission sticks and vertical threaded rods through a sliding cover.

Abstract: A driving mechanism for a massage chair, the massage chair has a primary frame and a massaging set, the primary frame having a vertical bidirectional screw rod, a passive member connected to the massaging set jacketed onto the bidirectional screw rod. The massaging set utilizes the driving motor to provide synchronized massage movements and vertical movements, and the massaging set engages with the passive member and the bidirectional screw rod such that when the massaging set reaches to the very top end or the very bottom end the bidirectional screw rod it directly changes its direction of movement without any sensor, which can reduce and simplify structural costs.

Abstract: An adjustable leg massager has a massage base, two connecting joints and a rotatable massage unit. The massage base has two symmetrical vertical openings at a front face, a plurality of first massage airbags disposed in the openings, and a first cover covering the first massage airbags. The two connecting joints have an upper joint portion and a lower joint portion pivoted together. A stop is disposed at an outer edge of the upper joint portion and adjacent to the pivoted position. The rotatable massage unit has two massaging sections corresponding to the vertical openings of the massage base, a plurality of second massage airbags disposed in the massaging sections, and a second cover covering the second massage airbags. The massage airbags have a plurality of individual massage regions and each massage region is connected with an outlet.

Abstract: A muscle stretching structure for a foot massager includes a massaging base, two rocking boards, a first supporting element and a second supporting element. The massaging base has two bottom spaces, a first supporting surface and a second supporting surface, and a lifting unit disposed on each first supporting surface. Furthermore, a bottom side of each rocking board is attached to a respective rocking module. The first supporting element has two containment spaces and is pivoted to the first supporting surface of the massaging base with the first hinges. A second supporting element has two upper spaced and a driving unit is attached to the bottom of the second supporting element. The driving unit is disposed between the second supporting element and the second hinges.

Abstract: A driving mechanism for a massaging device includes a housing, a driven gear rotatably mounted in the housing, a driven shaft secured to a first side of the driven gear, and an adjusting shaft mounted on a second side of the driven gear. Thus, when the driven gear is rotatable in a first direction, the adjusting shaft and the driven shaft are rotated with the driven gear simultaneously, so that the two swinging members are moved in the same direction, and when the driven gear is rotatable in a second direction, the adjusting shaft and the driven shaft are rotated with the driven gear with a time lag, so that the two swinging members are moved in the opposite direction.

Abstract: A massaging device includes a propeller shaft, at least one first swinging member mounted on the propeller shaft, and at least one second swinging member mounted on the propeller shaft by a male deflection block, a female deflection block and an adjusting rod. Thus, when the rotation direction of the propeller shaft is changed, the push block of the adjusting rod is slidable in the adjusting groove of the male deflection block to produce a time lag of the swinging actions between the second swinging member and the first swinging member, so that the second swinging member and the first swinging member are operated in the same swinging direction or in two different swinging directions so as to produce different swinging actions, thereby providing different massaging effects to the user.

Abstract: A reclining leisure chair includes a base frame, a seat frame, a backrest frame, a hassock frame, a driving device, and a link rod. The driving device enables the seat frame and the backrest frame to be adjusted for reclining at the same time. The link rod is pivotally fastened at one end to the backrest frame, and at the other end with a pivoting portion of the seat frame. In conjunction with a control rod of the seat frame, the link rod enables the backrest frame to be adjusted for reclining independently. The hassock frame is pivoted with the link rod.

Abstract: A massaging device is designed for use in conjunction with a leg frame of the massaging chair. The massaging device includes a plurality of clamp boards and massaging wheels. The clamp boards are mounted slantingly to effect a tilting motion for massaging the shank of leg and the sole of foot. The massaging wheels are eccentrically mounted to bring about an eccentric motion for rubbing the shank of leg and the sole of foot.

Abstract: A reclining chair is formed of a base frame, a seat frame, and a backrest frame. The base frame is provided with two horizontal slide rails and two inclined slide rails. The seat frame is provided with two first slide wheels slidable on the horizontal slide rails, and two second slide wheels slidable on the inclined slide rails. The backrest frame is fastened at one end to the seat frame such that the backrest frame reclines along with the seat frame.
