Abstract: A variable pressure injection mold, an injected shoe material, and a method for manufacturing the same are provided. The variable pressure injection mold for plastic injection molding includes a mold body and a variable pressure air discharge layer. The mold body has a foam molding space. The variable pressure air discharge layer is arranged on the mold body and is correspondingly exposed to the foam molding space. A plurality of variable pressure pores are provided in the variable pressure air discharge layer and the variable pressure pores connect the foam molding space.

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.

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.
