Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a container box that can be moved to any desired location on casters, such as a dust box used in garbage collection work in a garbage truck.

Conventional technology Recently, in order to reduce labor during garbage collection work and improve work capacity, dust boxes with casters have been installed in locations that do not obstruct road traffic, and garbage is thrown into them during collection. The dust box is moved by the worker to the input port of the garbage collection vehicle,
This is automatically turned over above the input port and the garbage is thrown into the cargo box.

Problems to be Solved by the Invention Usually, the above-mentioned dust box has casters attached to the four corners of the bottom, and the casters allow it to be moved to any desired location. However, although there is no problem with the dust box on a flat road, it is difficult to move the dust box as desired to the input port of the garbage collection vehicle on a sloped or highly uneven road. This is because when the dust box is moved, the wheels of each caster attached to the four corners of the bottom of the dust box rotate freely around the axis at a predetermined angle with respect to the wheel axis. This is caused by turning due to unevenness. By the way, if it is not possible to move the dust box as desired to the input port of the garbage collection vehicle during garbage collection work, it is labor intensive and work efficiency is poor, which is undesirable.

Therefore, an object of the present invention is to provide a container box that solves the above problems.

Means for Solving the Problems In order to achieve the above object, the present invention provides a container box in which a plurality of casters are rotatably attached to a plurality of predetermined positions on the bottom of the main body, and a plate is attached to one of the plurality of casters. The outer edge of the plate is fixed so as to protrude outward from the side plate of the main body, and a plurality of lock pin insertion holes consisting of long arc-shaped holes are bored in the outer edge of the plate at regular intervals around the circumference. To provide a container box equipped with a locking mechanism which has a lock pin inserted into the lock pin insertion hole of the plate and can be inserted into and removed from the lock pin insertion hole of the plate with one touch by depressing a lock release pedal. .

Effect According to the present invention, by fixing one of the plurality of casters to the main body by a locking mechanism, the remaining casters are fixed to the above-mentioned one when moving.
Because it is pulled by several casters and aligned in the same direction, it can move smoothly in a predetermined direction.

Embodiment Hereinafter, an embodiment in which the present invention is applied to a dust box will be described based on FIGS. 1 to 3.

In the drawing, 1 is a bottomed box-shaped main body with an open top so that garbage can be thrown in, and 2 is a caster rotatably attached to a plurality of predetermined positions on the bottom surface of the main body 1, for example, at each of the four corners. bottom plate 1
A wheel 2c is rotatably mounted on a bifurcated leg frame 2a via a shaft 2b. 3 is one caster 2 out of 4
It is a disc-shaped plate attached to the leg frame 2a by welding or the like, and has a plurality of lock pin insertion holes, for example, four arc-shaped long holes, on the outer peripheral edge that protrudes outward from the side plate 1a of the main body 1. 3a are bored at equal intervals around the circumference. Reference numeral 4 denotes a lock mechanism installed on the side plate 1b of the main body 1 in correspondence with the outer peripheral edge of the plate 3 protruding outward from the side plate 1b, and is inserted into a lock pin insertion hole 3a formed in the outer peripheral edge of the plate 3. By inserting the lock pin 4a into the lock pin insertion hole 3a of the plate 3, the plate 3 is locked with respect to the main body 1 to prevent the caster 2 from turning. The lock mechanism 4 is provided with a lock release pedal 4b, and when the lock release pedal 4b is depressed, the lock pin 4a rises and locks into the lock pin insertion hole 3a of the plate 3, as shown by the dashed line in FIG. As a result, the plate 3 is unlocked from the main body 1 and the caster 2 can rotate. Further, when the lock release pedal 4b is released from its depression, it is configured so that it automatically returns to its original position and the lock pin 4a is lowered, and the lock pin 4a is lowered and inserted into the lock pin insertion hole 3a of the plate 3. This locks the plate 3 against the main body 1 and prevents the caster 2 from turning. Therefore, in the lock mechanism 4, the lock pin 4a can be inserted into and removed from the lock pin insertion hole 3a of the plate 3 with a single touch using the lock release pedal 4b, thereby preventing the caster 2 to which the plate 3 is attached from turning and preventing the rotation of the caster 2. Cancellation can be easily performed.

When in use, after the wheels 2b of the caster 2 with which the plate 3 is attached to the leg frame 2a are directed in the direction in which the dust box is to be moved, the plate 3 is locked to the main body 1 by the locking mechanism 4, and the caster 2 is rotated. By preventing rotation, the caster 2
The direction is fixed with respect to the main body 1. In this state, that is, with one of the four casters 2 fixed relative to the main body 1 in the direction in which the dust box is to be moved, when the dust box is moved in a predetermined direction, the main body 1 The other caster 2 is pulled by one caster 2 whose direction is fixed relative to the other 3.
The casters 2 are aligned in the same direction, and the dust box moves smoothly in a predetermined direction.

Next, when changing the moving direction, the lock pin 4a of the lock mechanism 4 is removed from the lock pin insertion hole 3a of the plate 3 using the lock release pedal 4b to release the lock by the lock pin 3a of the plate 3, and the main body 1 is released. After one caster 2, whose direction is fixed relative to the
Fix the direction to.

Effects of the invention As explained above, according to the invention, by fixing the direction of one of the plurality of casters to the main body, the remaining casters are pulled by the one caster during movement. Since they are stretched and aligned in the same direction, they can be moved as desired even on sloped or uneven roads, thus reducing the labor of the worker and improving work efficiency. Further, since the present invention uses a locking mechanism that allows the lock pin to be inserted and removed with one touch into the lock pin insertion hole of the plate, it is possible to easily prevent and release the rotation of the caster. In addition, in the present invention, the lock pin insertion hole drilled in the plate is formed into an arc-shaped long hole, so even if the lock pin is inserted into the lock pin insertion hole of the plate to prevent the caster from turning, the caster will still However, it is possible to turn slightly by the length of the long hole, and the slight swing of the caster can be used to move while adjusting the traveling direction, resulting in good workability.
