According to a second aspect of the present invention, in the first aspect, the gripper has a fixed claw and a movable claw slidable in a direction to approach or separate from the fixed claw. Features.

According to a third aspect of the present invention, in the first or second aspect, the movable claw is urged in the direction of the fixed claw, and the movable claw is normally attached to the base at a predetermined distance from the fixed claw. In order to prevent the above-mentioned separation, a latch for engaging with the movable claw is provided.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the base provided with the gripper is a leg capable of extending and contracting up and down with respect to the base of the caster. It is characterized by being connected via a part.

According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the leg is extendable by a down petal and an up petal.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a caster having wheels 1a, and a pedestal 1b of the caster 1 is provided with a leg 2 which can be extended and contracted by a fixed stroke. A base 3 is integrally provided on the upper part of the leg 2, and a gripper 4 for gripping a frame of cargo handling equipment such as the mesh container or the rack is mounted on the base 3.

The leg 2 has a known telescopic mechanism used as, for example, a stopper of a bogie. When the down petal 5 is stepped on, the leg 2 is extended and held in that state.
When the up petal 6 is depressed while the leg 2 is extended, the leg 2 returns to its original state.

On the other hand, the gripper 4 has a pair of fixed claws 7 and movable claws 8. That is, at one end on the base 3,
A fixed claw 7 having a horizontally extending locking piece 7a that engages with the frame of the cargo handling equipment is fixed to the top end. At the other end of the base 3, a movable claw holding portion 9 is integrally erected. A pin 10 is slidably fitted into the movable claw holding portion 9, and a movable claw is attached to the tip of the pin 10. 8 is attached. At the tip of the movable claw 8, there is provided a locking piece 8 a that extends in the horizontal direction at the top end and engages with the frame of the cargo handling equipment together with the locking piece 7 a of the fixed claw 7.
A coil spring 11 for urging the movable claw 8 in the direction of the fixed claw 7 is interposed between the movable claw holding portion 9 and the movable claw holding portion 9. A handle 12 is provided at the other end of the pin 10.

Further, a dial-type latch 13 is mounted on the base 3 between the movable claw 8 and the movable claw holder 9 so as to move in the same manner as a latch used for a general door or the like. That is, the base 3 has the latch frame 13a
And a latch 13b urged upward by a spring (not shown) on the latch frame 13a.
And the latch 13 b protrudes from the upper surface of the base 3. The surface of the latch 13b facing the movable claw 8 is formed vertically, and an inclined surface that is inclined obliquely downward is formed on the opposite side. By turning the dial 13c, the latch 13b is housed in the latch frame 13a. It is.

Therefore, in normal times, even if the handle 12 is pulled, the movable claw 8 comes into contact with the latch 13b, and the movable claw 8 does not move further away from the fixed claw 7. Therefore, when the dial 13c is turned, the latch 13b is stored in the latch frame 13a, and the movable claw 8 can freely slide. When the dial 13c is released, the latch 13b projects above the base, but when the movable claw 8 urged by the coil spring 11 abuts against the latch 13b, the latch 13b is lowered by the inclined surface formed on the latch 13b. Then, the movable claw 8 is freely moved in the direction A and returns to the original state.

[0016] On the other hand, the leg 2 is stretchable as described above, when the leg 2 is contracted the height h ₁ of the caster, the height of the base of the mesh that you are installing H (Figure 2) becomes lower than, if extending the leg height h ₂ of the casters are set higher than the base height of the mesh.

When the caster is used, the stopper of the latch 13b is released by turning the dial 13c of the dial type latch 13, and the movable claw 8 is held by the handle 12 against the coil spring 11 in FIG. The space between the fixed claw 7 and the movable claw 8 is widened by sliding to the right. Then, in this state, the gripper 4 is fitted between the stitches 15b (FIG. 2) from the lower part of the frame 15a of the cargo handling equipment 15 such as a mesh, and the handle 12 is released. The cargo handling device 1 is moved in the direction
The frame 15a is sandwiched, and the caster 1 is attached to the cargo handling equipment 15 with one touch.

After the casters 1 are attached to the four corners of the cargo handling equipment 15 in this way, the legs 2 of all the casters 1
When the down petal 5 is depressed, the leg 2 is extended, the cargo handling equipment 15 is lifted by the grounding of the caster 1, and the caster 1 can be transported.

After the cargo handling device 15 is transported, when the up petal 6 of the leg portion 2 is stepped on, the leg portion 2 contracts to its original state, the casters are separated from the ground, and the cargo handling device is grounded. Therefore,
The casters can be removed by opening the gripper 4 in the same manner as when the casters are mounted.

As described above, the fixed pawls 7 and the movable pawls 8 of the caster are opened and fitted into the frame 15a of the cargo handling equipment, and the fixed pawls 7 and the movable pawls 8 are closed to easily move the caster 1 to the cargo handling equipment 15. And the caster 1 does not come off the frame 15a of the cargo handling device 15 unless the latch 13b is released. Furthermore, the lifting and lowering of the cargo handling equipment 15 can be easily performed by the expansion and contraction of the legs, and the transportation of the cargo handling equipment 15 can be easily performed.

[0021]

As described above, the present invention is constructed as described above, so that the caster according to the present invention can be easily transported by attaching it to the cargo handling equipment regardless of whether the cargo handling equipment is loaded. Moreover, even when the casters are removed, the casters are stored one by one, so that the storage space can be reduced.
