Abstract: The present invention provides a ratio mechanism of an automatic multiple-folding umbrella, cooperating to cooperating to the opening mechanism, and main stick assembly and said handle control mechanism; wherein said terminal pulley of said ratio mechanism has a pulley for threading said inner stay wire over so that one end of said inner stay wire is fixed on said pulley assembly, and the another end is threaded through said pulley on said terminal pulley base, and the pulley of said pulley assembly, then passing through said terminal pulley base to be fixed on said locking head; said main stick is composed of four stick segments. Due to building up said switch, repeat press down said button can bring into being automatic opening and closing umbrella function.

Abstract: A variable ratio control shoe with automatic tying and untying shoelace, with automatic lace tying process controlled by a variable ratio control mechanism and untying process controlled by a control mechanism in the laminated layers of the shoe body, its construction comprising a set of tying component, an adjustment mechanism to adjust tension, a modulated sole lamination having at least one assembling space, and a modulated control mechanism assembled in the control groove at the rear of the outsole, to engage the tying shoelace or disengaging the shoelace to take off the shoe, having the advantages of modulated control, mass production, low waste product rate and low costs.

Abstract: This invention relates to shoes with an automatic shoestring tying/untying device, and particularly to an automatic shoestring tying or untying device which is synchronous with wearing/taking-off action, and in which the tightness is adjustable. The device has a tying mechanism, slidable action and adjustment mechanism in the sole space, and shoestrings are inserted in the tying mechanism and extending through a shuttle piece and adjustment mechanism. The shuttle piece slides back and forth to let shoestring be tightened when wearing the shoes or to be automatically loosened in accordance with taking off the shoes. Adjustment of the arm adjusts the shuttle piece moving stroke to adjust the tightness of the shoestrings.

Abstract: This invention is an umbrella in automatic opening and closing manner with its rod in the middle, which has multiple sections, and it is in variable dynamic process including the umbrella's skeleton mechanism, spring, locating device, shuttle arrow, control mechanism, handle, change-over device and pulling rig. Its main novelty is that within the middle rod of the umbrella's skeleton, a contrivance to change is installed. At the ends of the pulling rope in the contrivance to make changes, they respectively reach the lower nest and shuttle arrow. The control mechanism is manipulated by the pressing of of the button to release the umbrella's skeleton in particular position for closing and folding and the reserve energy of the spring. In coordination with both pulling ropes, each section of skeleton is tracted to extend and make the upward movement of the lower next to open the umbrella. The locating device fastens the middle rod at the fixed position to resist against wind.

Abstract: This invention relates to a double-locking adjustable brace especially one which comprises an inner rod, an outer tube, a locking device consisting of two cams, two brake shoes. A spring and a driven plate, and a torsion reducer consisting of a plastic cover, a pivot screw and a concave support. The inner rod is telescopically fitted in the outer tube so that the brace is adjustable in length. The inner rod disengages and engages one of the cams by means of internal and external toothings so that the cams of the locking device can be turned to expand and make the brake shoes to grip the outer tube. The torsion reducer consists of a special washer, a screw pivot, a metal support and a plastic cover and is constructed in such way that the plastic cover can turn freely on the screw pivot to reduce the torsion incidentally applied on the brace.

Abstract: This invention relates to a disposable container and in particular to one having an inner cup provided with a vertical front wall, a vertical rear wall, two vertical side walls and a bottom, and an outer cup provided with a bottom plate and four flaps extending from respective sides thereof. The inner cup is adhered to the outer cup and has folding lines to enable the inner cup together with the outer cup to be folded into a sheet. Further, a pulling line is passed through the upper edges of the inner cup and outer cup so that when the pulling line is pulled, the sheet will be pulled open to form a container.

Abstract: An improved ellipsograph for drawing ellipses, ovoids and circles comprises a frame, a slide block, a disc, a worm wheel, a pivot adjusting block, a stub adjusting block, a motor, a battery holder and a drawing arm. The disc and the worm are screwed together and fitted in the round opening of the slide block. The pivot adjusting block and the stub adjusting block are fitted respectively in the worm wheel and the disc. When the motor is started the screw shaft will cause the worm wheel to turn and the pivot on the pivot adjusting block will circumambulate with the worm wheel. At the same time, the stub on the stub adjusting block fitted in the slot of the frame will roll along the slot due to the tangential force of the worm wheel and cause the slide block with the worm wheel and the disc as a whole to move straightly back and forth.

Abstract: An improved ellipsograph capable of drawing dotted or dashed lines comprising a drawing unit with a small motor which drives a pen holder and two pull discs causing them to turn synchronously to draw ellipses in any shape from real circle to horizontal line by adjusting the radius of circumambulation of the pen and of the puller carriers, and a drawing control unit for controlling and selecting a dotted or a dashed line.
