Abstract:
A massage apparatus includes an upright frame member having a parallel pair of vertically extending guide rails, and an externally threaded screw shaft mounted on the frame member and disposed parallel to and between the guide rails. A slide frame extends between the guide rails and is coupled slidably thereto so as to be movable upwardly and downwardly therealong. A massage drive unit is mounted on the slide frame, and includes an upright rotatable drive shaft having a lower end provided with a first gear and an upper end provided with a second gear, and a massaging roller assembly driven by axial rotation of the drive shaft for imparting a massaging action. A first transmission belt is coupled to a motor on a lower frame part of the slide frame and the first gear so as to enable the motor to drive the drive shaft to rotate axially. A coupling unit is mounted on the upper frame part of the slide frame, and includes a rotary member coupled threadedly and rotatable relative to the screw shaft. A second transmission belt is coupled to the second gear and the rotary member so as to enable the second gear to drive rotation of the rotary member, thereby enabling the rotary member to move upwardly and downwardly along the screw shaft to result in corresponding upward and downward movement of the slide frame.
Abstract:
An adjusting device for seating and reclining furniture includes a basis case, a screw rotatable axis, a guide area, an adjuster and a side cover. A notching is set at the upper end face of the guide area. A slider inside of the adjuster is combined with the upper wall of a perforating in the guide area by a connection portion. The width of the connection portion is set corresponding to the width of the notching of the guide area, and a perforated panel is set at the center of the connection portion to make a fender board impenetrate. The fender board may shield the notching of the guide area. A chamber is set in the upper end face of the adjuster corresponding to the position of the perforated panel from top to bottom. The chamber may hold a felt containing lubricating oil. There is a bearing chamber in the inner wall of the side cover. The bearing chamber may make the bearings embed in, and a bearing are pivoted and combined with the end of the screw rotatable axis.
Abstract:
In a massage device, a rotary drive shaft is disposed uprightly in a hollow casing. Parallel upper and lower output shafts are mounted transversely in the casing, and have opposite end portions that extend out of the casings. An upper gear set includes an upper drive gear sleeved rigidly on the drive shaft for co-rotation therewith, and an upper driven gear meshing with the upper drive gear and connected rigidly to the upper output shaft. A lower gear set includes a lower drive gear disposed coaxially on the drive shaft, and a lower driven gear meshing with the lower drive gear and connected rigidly to the lower output shaft. A unidirectional bearing is disposed between the drive shaft and the lower drive gear to prevent rotation of the drive shaft from being transmitted to the lower output shaft when the drive shaft rotates in a first direction, while permitting rotation of the drive shaft to be transmitted to the lower output shaft when the drive shaft rotates in a second direction opposite to the first direction. Two linkage units, disposed on the lateral sides of the casing, are mounted on the end portions of the output shafts and are provided with massaging wheels.
