Abstract: A modular glass door assembly includes a door, an inner frame, and an outer frame. The door has a glass door leaf and a doorframe mounted to the outer periphery of the glass door leaf. The inner frame is attached to the outer periphery of the doorframe and connected to the doorframe by two hinges up and down. The outer frame has four frame strips arranged around the outer periphery of the inner frame and each provided with a concave portion engaged with one respective convex portion of the inner frame. By this way, the inner frame and the outer frame can be directly assembled with each other or a fixed window panel can be added between the inner frame and the outer frame. Thus, the modular glass door assembly of the present invention has advantages of easy assembly and high scalability.

Abstract: A movable bearing device includes a base, a plurality of casters, and a plurality of foot pads. The casters are provided on the bottom of the base. The foot pads are movably connected to the bottom of the base in a way that the foot pads are moved upwards and downwards with respect to the base. When the foot pads are moved downwards until their bottom surfaces each have a height equal to or lower than the bottom edges of the casters, the movable bearing device is supported on the ground by means of the foot pads, such that the movable bearing device cannot be moved. When the foot pads are moved upwards until their bottom surfaces each have a height higher than the bottom edges of the casters, the movable bearing device can be moved by means of the casters so as to facilitate the handling work.

Abstract: A foldable table leg includes a vertical pole, an inclined pole and two positioning members. The vertical pole is provided on the peripheral surface thereof with two protruding lugs facing each other. An end of the inclined pole is pivotably connected to the protruding lugs of the vertical pole in a way that the inclined pole is pivotable relative to the vertical pole between an unfolded position and a folded position. The positioning members fasten the protruding lugs of the vertical pole to an end of the inclined pole in a detachable manner, for positioning the inclined pole at the unfolded position. When the positioning members are detached, the inclined pole is pivotable from the unfolded position to the folded position, so that the objective of reducing the cubic volume and saving space is attained after the inclined pole is folded.

Abstract: A tabletop elevation adjustment mechanism includes a fixed outer tube, a movable inner tube vertically movable in the fixed outer tube, and a plurality of corrugated sheet members equiangularly fastened to a bottom of the movable inner tube. Each of the corrugated sheet members has a plurality of first and second ridge portions respectively protruding toward two opposite sides thereof. The first ridge portions elastically stopped against an outer surface of the movable inner tube and the second ridge portions elastically stopped against an inner surface of the fixed outer tube.

Abstract: A chair with a pre-pressing structure includes a chair body and a pre-pressing structure enabling the chair body to be provided with elastic restoring force. The chair is characterized in that the pre-pressing structure includes a pre-pressing member's fixed seat, a pre-pressing member, a pivoting seat, a pre-pressing positioning member and a pre-pressing angle.

Abstract: A seat guiding apparatus for a chair includes a base, an elastic assembly mounted in the front end of the base and having a torsion spring and a moveable plate abutted against the torsion spring, and a seat assembly provided with a seat and a bracket connected with the seat. The bracket of the seat assembly has a front end connected with the moveable plate and a rear end movably mounted in curved guiding grooves of the base, such that the seat assembly is moveable along the curved guiding grooves relative to the base. As a result, when sitting on the seat, a sitter' back can be guided by the movement of the seat assembly to lean against a backrest of the chair for support.

Abstract: A chair adjustment structure includes a base member, a top cover pivotally connected to the base member, a spring member connected between the base member and the top cover, and a back bracket pivotally connected to the base member and the top cover. Therefore, when the user sits on the seat pad of the chair, the back bracket is forced to pivot the top cover to provide the user with sitting comfort.
