Abstract: A structure for assembling chair bases by cladding the chair bases with wood grain finish strips is provided. The chair bases have notched slots formed at appropriate placed on both sides of each plastic strut foot. A scoop channel is formed in the strut foot surface near the central pivot joint of the base. A drilled hole is located inside the scoop channel. A connecting hole is formed in the outer bottom edge of each strut foot for attaching a wheel set thereto. There is a wood grain finish strip for each strut foot. Each strut foot has an inverted U-shaped cross-sectional contour and pintle hooks located in correspondence with the notched slots on both sides of each strut foot. The outer bottom edge of each wood grain finish strip extends inwardly to form a flange of suitable length to extend over the outside of the strut foot.

Abstract: An armrest unit having a top plate with wood grain patterns including a plastic injection molded armrest and a decorative top plate. The armrest has an upper surface provided with a peripheral depression and an array of spaced coupling holes, each of which has a positioning hole of a larger diameter at a bottom end. The decorative top plate is sized and shaped to match the upper surface of the armrest and has an inverted U-shaped cross section. The decorative top plate is further provided with a plurality of spaced retaining elements for engaging the coupling holes of the upper surface of the armrest such that the decorative top plate can be firmly and integrally fitted onto the upper surface of the armrest to enhance the appearance of the armrest.

Abstract: An automatic water supply device for potted plants is provided. The device includes a housing having a reservoir incorporated therein, the reservoir being equipped with a plurality of supporting ribs, the disk member having a plurality of draining holes formed along its periphery. An observation hole is formed through the disk member for measuring the water level of the reservoir. The disk member is further provided with a through opening formed in the center portion thereof. A water controlling sleeve, which is made from plastic material, is positioned within the central opening of the disk member. The sleeve member is formed with a passage formed through its length. The sleeve member has a first bead portion on one end and a second bead portion below the first bead portion. The distance between the first bead portion and the second bead portion is equivalent to the thickness of the disk member.
