Abstract: A method of fastening a flexible sheet-like structure on a tubular winding shaft including: introducing, in a circumference of the tubular winding shaft, at least one aperture which passes through a wall of the winding shaft, a width of the aperture being greater than the thickness of the flexible sheet-like structure, cutting into the flexible sheet-like structure to produce at least one angleable tab, and inserting the tab into the aperture of the winding shaft. Additionally, a roller blind includes a winding shaft and a flexible sheet-like structure fastened thereon.

Abstract: A foldable door includes two door panels each having a rounded adjacent side. A safety member is disposed in the gap formed between the door panels and includes two curved recesses for engaging with the rounded adjacent sides of the door panels. Two couplers are secured to the safety members and each includes two shafts engaged in the door panels for pivotally coupling the door panels together and for allowing the door panels to be rotated about the shafts. The safety member may enclose the gap for preventing a user from being hurt between the door panels.

Abstract: A truck cover protector encases the movable end of a truck cover to prevent damage to the truck cover while the cover is in position over the truck body. The spindle carrying the rear end of the cover is encased in a plastic cover. When the reel for the cover is at the front of the truck, the cover protector is fixed to the cover material. When the reel for the cover is on the movable spindle, the cover protector is large enough to receive the reel therein; and, end members are fixed to the protector and allow the spindle to rotate for reeling and unreeling the cover.
