Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a dust container for storing garbage.

(Prior Art) In a hanging container, since it is necessary to discharge garbage onto a vehicle, it is desired that the opening operation of the bottom plate at the time of discharge is easy. It is also desired that the bottom plate be easily closed since it is necessary to ground the container again after release. One of the products developed in response to these demands is the one disclosed in Publication of Utility Model Publication No. 45-7984.

(Problems to be Solved by the Invention) However, in this device, both the locking members sandwich the blocking member, thereby preventing the locking pin from separating from the locking member. Therefore, the blocking member may wear out and contract in diameter over time. In this case, both the locking members come closer to each other and pinch the blocking member, but on the side that pinches the locking pin, they become further apart, making the locking unstable. Therefore, when the container is suspended and the weight of the container acts on both of the latching members, the effect of causing the blocking member to slide out becomes greater, and there is a possibility that the bottom plate may be opened inadvertently.

In view of these points, it is an object of the present invention to provide a dust container that can maintain a stable locking state regardless of changes over time.

(Means for solving the problems) In order to achieve the above object, the present invention is configured as follows. That is, the present invention is a box-shaped dust container that has a bottom plate that can be opened and closed on the lower surface of the side plate and is configured so that the whole can be suspended. On one side, the extension part is arranged vertically and the rotation center of the bottom plate is set at the upper end thereof, and on the lower part of the outer wall of the side plate at the position opposite to the other edge, which is the free end side of the bottom plate, A hollow bracket is attached, and a locking mechanism for the bottom plate is housed inside the bracket, and the locking mechanism is pinned to a lower part of the bracket and can be tilted toward and away from the free edge of the bottom plate. a locking plate, a lock shaft fixed to the surface of the locking plate on the side facing the bottom plate and capable of engaging and detaching from the lower surface of the free end side of the bottom plate as the locking plate tilts; and a lock shaft on the back side of the locking plate. a locking spring provided on the bracket and biasing the lockshaft in a direction to lock the bottom plate; an unlocking shaft rotatably supported on the upper part of the bracket and having an operating lever at one end for unlocking; an abutment plate fixed downwardly to the unlocking shaft and abutting against the inner surface of the upper end of the locking plate so as to push the locking plate away from the bottom plate in accordance with an unlocking operation by the unlocking shaft; It was decided to consist of the following.

(Function) Therefore, according to the above configuration, when closing the bottom plate of a suspended container, it is possible to automatically close and lock the container by simply lowering the container. That is, as the bottom plate closes, the free edge pushes the lockshaft and locking plate against the lock spring. Then, when it gets over the lockshaft, it returns to its original position under the force of the spring, so that the lower surface of the bottom plate is received by the shaft.

Conversely, to release the lock, the lever is operated to rotate the unlocking shaft. By doing this, the locking plate is pushed rearward via the backing plate, so that the engagement state by the lockshaft is released.

(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

In the drawings, reference numeral 1 denotes a metal dust container formed into a box shape, and has four side plates 4 as side walls. The upper opening surface of the container 1 is covered by a top plate 6 having a hanging tool 5 at the center of the upper surface. This top plate 6 is equipped with edge frames 9, 9 in which a garbage inlet is opened, and both inlets are provided with two cover plates 8, 8 which are attached to be openable and closable by a rotation shaft 7. It's covered. On the other hand, the lower opening surface of the container 1 is closed by a bottom plate 3. A pair of legs 2, 2 are attached to both ends of the bottom plate 3, and hold the bottom plate 3 in a floating state from the installation surface.

Next, we will discuss the mounting structure of the bottom plate 3 and the lock mechanism 1.
1 will be explained (see FIGS. 3 and 4).

A reinforcing angle member 12 is attached to the lower end of the side plate 4. On one side wall of the dust container 1, support mechanisms for the bottom plate 3 are provided at two positions on the upper surface of the angle member 12 at appropriate intervals. In each support mechanism, a pair of L-shaped receiving members 13 are faced to each other, and between them,
A gap maintaining material 18 is interposed. A support arm 15 is vertically housed between these arms, and is pivotally supported by a pivot shaft 16 at the upper end. In addition,
Interference with the angle member 12 is avoided by providing a notch 14. On the other hand, this support arm 1
The lower part of 5 is welded to the angle 17 of the bottom plate 3. In this way, the rotation support shaft 16, which is the center of rotation of the bottom plate 3, is located at a predetermined height from the bottom plate 3 and is provided outside the side plate 4, so that the container 1
When it is suspended and the bottom plate 3 is opened, its tip (free end side) will be inside the vertical line passing through the pivot shaft 16.

A bottom plate 3 is attached to the side plate 4 on the opposite side of the rotation center mentioned above.
A locking mechanism is provided for the That is, at the lower end of the side plate 4, two parts of the angle material 12 are cut out at appropriate intervals.
A rectangular cylindrical bracket B is fixed to each. A locking plate 22 is housed vertically in the lower part of both brackets B. And the pin 2 at the bottom end
3, and as shown in FIG. 4, it can take a substantially vertical position and a backward tilted position. Further, a lock shaft 25 having a predetermined width is fixed to the inner surface side of the locking plate 22 (the side facing the bottom plate 3). This lock shaft 25 is for receiving the lower surface side of the locking pawl 24 formed protrudingly from the free end of the bottom plate 3 (locking the bottom plate 3).
When the locking plate 22 is in the backward tilted position, the lock is released. Also, lockshaft 2
5 is connected to the lower end of the locking plate 22 by a guide plate 25. Further, a locking spring 26 is elastically mounted on the back side of the locking plate 22 (the side opposite to the bottom plate 3), and urges the locking plate 22 counterclockwise in FIG. 4.

For both brackets B, unlock shaft 20
is inserted horizontally and rotatably along the side plate 4. Further, one end of the unlocking shaft 20 extends outward from the side plate 4 and is bent at a substantially right angle to form a lever 19 for operation.
Furthermore, a backing plate 21 is welded to the unlocking shaft 20 and extends diagonally downward so that it can engage with the upper end of the locking plate 22. Can be tilted backwards.

Subsequently, the effects of this example configured as described above will be specifically explained.

When collecting garbage inside the container 1, the container 1 is
The whole thing is hoisted up and placed above the loading platform of the recovery vehicle. In this state, twist the lever 19. Then, since the backing plate 21 swings counterclockwise in FIG. 4, the locking plate 22 tilts backward against the locking spring 26. As a result, the lock shaft 25 is disengaged from the locking pawl 24 and the locked state is released, so that the bottom plate 3 is opened about the pivot shaft 16, and as a result, the dust inside falls onto the loading platform.

By the way, when the lever 19 is twisted, in this example, the backing plate 21 is brought into contact with the upper end of the locking plate 22, so that the lock can be released even with a light operating force.

Note that when the lever 19 is released after opening the bottom plate 3, the locking plate 22, the backing plate 21, etc. are released by the locking spring 2.
6, it returns to its original position, that is, the lock position.

When the container 1 is to be reinstalled after the garbage collection is completed, the container 1 is lowered to its original location with the bottom plate 3 left open. In this case, as mentioned above, the free end (open end) of the bottom plate 3 is located inside the vertical line passing through the rotation support shaft 16, so
Simply lower the container 1, and the bottom plate 3
When the free end of is grounded, it automatically rotates in the closing direction. After the locking pawl 24 of the bottom plate 3 contacts the guide plate 27, the locking plate 22 is tilted backward by sliding while pushing the same plate 27, and when the locking plate 22 is climbed over the lock shaft 25, the locking plate 22, The lock shaft 25 is returned to its original position by a lock spring 26. In this way, the bottom plate 3 is automatically locked.

Incidentally, in this example, the surface side of the guide plate 27, the surface of the lock shaft 25 on the side facing the bottom plate 3, and the upper surface may wear out over time, but they are always biased in the locking direction by the lock spring 26. Therefore, a locked state is ensured regardless of this wear.

(Effect of the invention) As is clear from the above explanation, when the dust container of the invention is in the locked state, the lock shaft is biased in the locking direction by the locking spring, so that the lock may be released inadvertently. The lock state is reliably maintained.

It is also possible that the lockshaft wears out over time, but in this case, the locking plate acts in the direction of approaching the bottom plate, that is, in the direction of locking, so there is no deterioration of the locking function over time.

Conversely, to release the lock, the lever is operated to rotate the unlocking shaft. By doing this, the locking plate is pushed rearward via the backing plate, so that the engagement state by the lockshaft is released. In this case, the lock can be released with a light operating force, resulting in excellent operability.
