Abstract: A combination of urine bag and skirt includes a skirt having at least one opening for a user to stretch therein his/her hand(s) conveniently; a urine bag having a bag opening, and being provided inside of the skirt; and a urine guide having a guide opening and a guide joint such that the guide joint is sleeved to the bag opening. The user can wear the skirt as a shelter, and stretches his/her hand(s), through the at least one opening, into the skirt, where the user can hold, with his/her hand(s), the urine bag and the urine guide such that the guide joint is sleeved to the bag opening so as to urinate. Therefore, the combination of urine bag and skirt has merits on easy cleaning and replacement, and on urination sheltering.

Abstract: A multi-functional window washing and wiping device comprises mainly a device body and a retractable rod connected to the device body, wherein on the device body are disposed a toothed gear assembly comprising a plurality of toothed gears and a vortex rod for driving the toothed gear assembly, whose two ends are pivotally connected to wheels disposed on two sides of the device body. At least two tube bodies are disposed above the device body. When using the present invention, assemble a cleaning tool such as a brush, a sponge, or a piece of cloth on the toothed gear assembly; input detergent and water via the tube bodies; and hold the retractable rod, place the device body on a glass window, and move the device body along the glass window. The purpose of washing glass windows in buildings is achieved by rolling the cleaning tool by driving the toothed gear assembly via wheels or a motor without the risk of having window washers hang in mid-air.

Abstract: A frame structure including at least one base rod; a plurality of struts respectively fastened to the at least one base rod; a plurality of shear members respectively fastened to the at least one base rod; and a plurality of horizontal connecting hooks, each having a first end fixedly connected to the at least one base rod and a second end terminating in a hooked portion. By connecting the connecting hooks of one frame structure to the connecting hooks of another, a plurality of frame structures are connected together to form a framework for a reinforced concrete floor.

Abstract: A reinforced bar connecting device fastened to two reinforcing bars to secure them in a line, including two plug members, and two symmetrical, smoothly arched coupling plates mounted around the reinforcing bars and abutted against each other and secured in place by the plug members to hold down the reinforcing bars, each of the coupling plate having a left longitudinal side edge, a right longitudinal side edge, and two longitudinal slots respectively made along the left longitudinal side edge and the right longitudinal side edge, each of the plug member being inserted into one longitudinal slot of each of the coupling plates.

Abstract: An apparatus for squeezing fluid out of the neck of a collapsible tube installed therein, including a base frame, a L-shaped supporting frame moved in the base frame in the longitudinal direction, an actuating plate pivotably connected to the back side of the vertical portion of the L-shaped supporting frame and having a push rod inserted through a hole on the L-shaped supporting frame, a cover board pivoted to the front side of the vertical portion of the L-shaped supporting frame, and a push plate suspending below the board and coupled to the actuating plate, wherein the push rod of the actuating plate is forced to push the cover board away from the neck of the collapsible tube and the L-shaped supporting frame is simultaneously moved toward the rollers to squeeze the collapsible tube when the push plate is depressed, thereby causing fluid to be forced out of the collapsible tube.
