Abstract: A detachable jacket for a bike seat includes: a jacket having an upper cushioning portion formed with a plurality of cells filled with pressurized fluid in the cells for a comfortable cushioning purpose for a bike driver sitting on the bike seat, and a lower skirt portion connected with the upper cushioning portion and protruding downwardly from the upper cushioning portion for telescopically retaining the jacket on the bike seat, whereby upon releasing of the jacket from the bike seat, the jacket can be repeatedly washed or conveniently maintained.

Abstract: A wall mounting support includes a shell fastened to a wall by an anchor and a screw, the shell comprising a front guard spaced from a front wall thereof with a receiving chamber defined therebetween for receiving the object to be supported. The front wall includes two resilient corrugated locating plates bilaterally obliquely disposed in an elongated opening of the front wall with a narrow sliding hole defined therebetween for permitting the screw head of the screw to be located at different symmetrical pairs of depressions on the corrugated locating plates.

Abstract: An air fan includes a plurality of fan blades each fan blade drilled with a plurality of perforations in the fan blade for reducing weight of each fan blade for reducing the electric energy required for driving the fan motor of the air fan. Each fan blade may be reinforced by at least a rib on a surface of each fan blade for enhancing its strength and preventing its deformation.

Abstract: A ceiling fan includes a plurality of fan blades radially secured to a motor shaft of a driving motor of the fan, each fan blade fixed with a holographic recording plate thereon pre-recorded with holograms of many sets of interference patterns of colorful decorative features within the recording plate, whereby upon a rotation of the fan blades as driven by the driving motor as being illuminated by a plurality of lamps, the patterns of color features recorded in each holographic recording plate will be observed with diversified color changes of the decorative features and superimposed decorative feaures with respect to a rotating angle as rotated by each fan blade, thereby enriching an optical decorative effect with simpler production, easier operation and minor maintenance problems of the fan.

Abstract: A cushioning device includes a plurality of liquid cells encapsulated in a flexible substrate sheet wherein each liquid cell is filled with water therein and the cells are juxtapositionally disposed on the sheet so that a cellular sheet may serve as a cushioning device for a user's seating, leaning or wearing for comfortable cushioning purposes.

Abstract: An illuminative fan includes a plurality of illuminators selected from light-emitting diodes juxtapositionally interlacedly disposed on each fan blade capable of being flashed or colored so that upon a rotation of the fan, the illuminators will produce diversified optical or colorful figures on the rotating blades due to persistence of human vision either flashingly or continuously for enriching a decorative effect for the illuminative fan.

Abstract: A towel support comprising a wall plate mounted onto a wall surface by anchors and screws, a connector to connect a hanging device to a toothed stem on said wall plate, wherein said connector has an axial hole into which said stem is inserted, a bolt hole vertically in communication with said axial hole, and a screw rod movably fastened in the gap between either two teeth on said stem to firmly secure said connector to said stem and prohibit it from rotary motion.

Abstract: A towel support, which includes a wall plate having a projecting stem and elongated mounting holes for easy alignment of flat head screws with anchors which are secured inside a wall, to fasten the wall plate onto the wall, and a connector to secure hanging device to the mounting plate for holding towels. The connector comprises an axial hole into which the stem of the wall plate is inserted, a bolt hole vertically in communication with the axial hole, and a screw rod movably fastening in the bolt hole pressing against the top taper end of the stem to firmly secure the connector thereto.
