Alternatively, it has a pair of wire-type operation amount transmission systems 19 for converting the movement amount of the inner wire (wire) 22 into a curved shape and transmitting the movement amount to each of the locking pins 17.

The turning operation member 18 is a metal rod.
Both ends are bent into a crank shape to form a crank-shaped bent portion 18a. The specific mounting position of the rotating operation member 18 is on the back side of the rectangular window 14b formed at the intermediate position of the front end of the pallet 14. However, the present invention employs a wire type operation amount transmission system 19. Therefore, even if the mounting position of the rotary operation member 18 on the pallet 14 is arbitrarily changed, the operability of the pallet hooking / unloading by the hook pin 17 does not decrease. The shape of the tip of the lock fitting 30 is the pallet 1
The hook pin 17 is warped outward so that the hook pin 17 can be smoothly guided into the pin hole 30a when the hook 4 is raised vertically. Each crank-shaped bent portion 18a is provided with an L-shaped extension piece 20 projecting therefrom. Since the extension piece 20 is arranged on the crank-shaped bent portion 18a in this manner, the amount of movement (movement stroke) of the inner wire 22 due to the turning operation of the turning operation member 18 increases.

The load is placed on 4 and the load is carried using the caster K.

When the pallet is stored, the pallet 14 is pivoted upward in a vertical plane about the pin 14a, and is raised to a substantially vertical state. At this time, each locking pin 17 collides with the lock fitting 30, and the locking pin 17 is guided to the front portion along the curved surface of the locking fitting 30 that has been warped outward, while receiving the spring force of the return spring 26. Pallet 14 against
It is pushed inside. When the locking pin 17 coincides with the pin hole 30a, the locking pin 17 is inserted into the pin hole 30a by the spring force of the return spring 26 and locked. Thereafter, the left panel 12 and the right panel 13 are folded inward in a horizontal plane so as to wrap the back panel 11 from the outside.
The roll box pallet 10 thus folded is
If necessary, the worker uses the casters K to transport the storage space.

As described above, since the locking means 15 having the wire type operation amount transmission system 19 is employed, the degree of freedom of the mounting position of the rotating operation member 18 on the pallet 14 is increased. As a result, the rotating operation member 18 is moved to the pallet 14
Can be arranged at any position.

[0021]

According to the present invention, the pallet can be operated with one hand. In addition, since a wire-operated type pallet hooking means is employed, the degree of freedom of the mounting position of the rotary operation member on the pallet can be increased.

In particular, according to the second aspect of the present invention, since the extension piece is provided on each of the rotation operation members, the amount of movement of the wire due to the rotation amount of the rotation operation member increases. As a result, the hook member can be reliably hooked and unhooked from the right panel and the left panel, respectively.
