<p>PROBLEM TO BE SOLVED: To provide a transport dolly with its front and back face frames made collapsible in a standing side by side condition where its front and back face frames are moved in parallel so as to be approached while being kept in an upright condition with its bottom plate raised up, so that these members can be folded up so as to be housed in a small size. SOLUTION: One end part of a bottom plate 5 is connected with the lower end part of either frame 3 of a front face frame and a back face 2 and 3 by a pin 9 in such a way as to be freely turned around, a rotary body 6 is mounted to the other end of the bottom plate 5, and the rotary body 6 is connected therewith in such a way that it can be moved up and down along supports 2a forming up the other frame 2 of the front and back face frames 2 and 3. One of the front and back face frames 2 and 3 is moved so as to be approached while being interlocked with the rising motion of the bottom plate 5, which forces the rotary body 6 of the bottom plate 5 to be lifted up along the supports 2a, so that these members are thereby folded.</p> |
