<p>PROBLEM TO BE SOLVED: To facilitate the switching of the storage condition and the service condition by a collapsible and storable truck, and to realize the compact storage in the stacked condition. SOLUTION: In a bottom plate, a bent floor plate 4 is interposed between a fixed floor plate 2 having casters 7 and a movable floor plate 3 having the casters 7. The bent floor plate 4 can be collapsed so as to be upwardly protruded. One end part 8a of a reinforced frame 8 is fixed to the lower surface side of the fixed floor plate 2, and the other end part 8b of the reinforced frame 8 is inserted into a holding piece 23 of the movable floor plate 3. A front handrail 16 and a rear handrail 19 are respectively fitted to the upper surface of the fixed floor plate 2 and the upper surface of the movable floor plate 3 to constitute a truck 24 for carriage. When a fixed rod 22 is removed during the storage in the truck 24 for carriage, the movable floor plate 3 is moved and the bent floor plate 4 is folded so that the center is projected (chain lines 24b, 3b, 4b). In addition, when the movable floor plate 3 is moved, the movable floor plate 3 having the rear handrail is collapsible so as to be brought closer to the fixed floor plate 2 having the front handrail 16 (solid line).</p> |
