Filed: 1992-12-25
Abstract: PURPOSE:To use a floor plate as a slope on which a working machine can be ascended by operating a pin to connect a frame erected on the ground to the floor plate on the second floor, a stopper of a stopper plate, and a lever to release the fixing of the floor plate. CONSTITUTION:A frame 1 to support a parking lot and a floor plate 2 on a second floor 101 are connected to each other rotatably by a pin 3, and the floor plate 2 on the second floor 101 is fixed horizontally by stopper plates 4 and released by a lever 5. In this case, the floor plate 2 is rotated around the pin 3 relative to the frame 1. Also, when one end of the floor plate 2 touches the placing surface of a working machine, the floor plate 2 forms a slope because there is a height difference between the connection section and the placing section of the frame 1 and the floor plate 2. Thus the floor plate can be used as a slope for ascending the working machine, and a plural-story parking lot for working machine can be obtained with minimum space by keeping the horizontal state of the slope by the stopper plate 4.

Title: Hydraulic cylinder
Inventor: MINAMIYOSHI YASUTOSHI
IPC: F15B11/00
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To lighten a shock at stopping a piston on a cylinder end and enable the piston to impulsively stop if necessary by providing a connecting oil passage bypassing a cushioning oil passage and connecting together an oil chamber on the moving end part side and an oil drain passage capably of being opened or closed. SOLUTION: In the case of an ordinary bucket work such as excavation or conveyance, an opening/closing valve 25 is in the closed state so as to close a connecting oil passage 24. In this state, when a piston 12 is moved up to a cylinder end on the head cover 16 side, oil in a cushioning chamber 22 is drained in a state of being restricted, a shock at stopping the piston on the cylinder end is lightened, and a quiet work of little vibration can be executed. Meanwhile, in the case such as letting fall soil stuck on a bucket, the opening/ closing valve 25 is opened so as to open the connecting oil passage 24. In this state, oil in the cushioning chamber 22 is drained through the connecting oil passage 24 without being restricted, the piston 12 is impulsively stopped, and hence soil and the like stuck to the bucket can be let fall. Consequently, workability is improved.
