Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a fire extinguisher storage box, particularly for storing cylindrical fire extinguishers for initial fire extinguishment in outdoor streets or indoor offices, hospitals, schools, general houses, etc. It is used as a box for carrying things.

[Conventional technology]

Foam and powder fire extinguishers used for initial fire extinguishing are generally cylindrical in shape and are placed outdoors along streets or indoors along walls. It is often stored in a storage box to prevent it from being knocked over or collecting dust.

Figure 4 is a diagram showing a conventional fire extinguisher storage box.
The container 1 has a substantially rectangular parallelepiped shape and is open at the front. A plate-shaped lid 2 is attached to the front surface with a hinge 3 so as to be openable and closable. These containers 1 and lids 2 are usually
Each piece is made in one piece by vacuum forming. That is,
The container 1 is molded from a single plastic plate by drawing a vacuum inside a mold, and the lid 2 is similarly molded from a plastic plate.

[Problem that the invention attempts to solve]

Conventional plastic fire extinguisher storage boxes, as shown in Figure 4, are widely used because the container and lid are integrally molded, and the manufacturing process is simple and lightweight, but they have the following drawbacks: It was hot.

That is, the container has a box shape, that is, the depth of the ceiling is the same as the bottom surface, and the fire extinguisher is housed inside the container, so it is difficult to grasp the handle on the top of the fire extinguisher when taking it out. Particularly in the initial stage of extinguishing a fire, there was a problem in using a fire extinguisher case because it was time to take out the fire extinguisher.

Furthermore, since this container is vacuum-formed from a single plastic plate, the wall thickness becomes thinner toward the back of the container (back panel), and a container that is too deep will not have enough strength, especially on the back side. This was a problem because it was easily damaged.

[Means for solving problems]

In order to solve the problems of the prior art described above, the present invention takes the following measures.

That is, the present invention is a vertical, substantially rectangular parallelepiped fire extinguisher storage box that stores a fire extinguisher in an upright position and is composed of a main body and a lid, and the vertical ridgeline on one side where the main body and the lid meet is joined by a hinge. By doing so, the lid can be opened and closed from the front like a door, and the depth of the lid is 10% or less of the total depth at the bottom and 40 to 80% of the total depth at the ceiling. The gist of this is a fire extinguisher storage box with different depths between the main body and the lid.

Hereinafter, the present invention will be specifically explained with reference to Examples.

1 to 3 show embodiments of the present invention.

In the figure, 1 is a container, 2 is a lid, and 3 is a hinge. 7 is a stored fire extinguisher. container 1
The bottom of the box is formed with wavy legs 4, and the depth of the bottom matches the depth of the entire box. The open surface of the container 1 is inclined, and the depth of the container at the ceiling is less than 1/2 (approximately 40%) of the total depth. Moreover, the ceiling part 5 of the container 1 is the highest at the joint with the lid 2,
The back side is low and sloped.

On the other hand, the bottom of lid 2 has no depth (depth 0%),
Although it is simply a single board, it increases in depth as it goes upwards, and the depth of the lid 2 at the ceiling is 1/2 of the total depth.
(approximately 60%). Moreover, the ceiling part 6 of the lid 2 is highest at the joint with the container 1, and is lower and sloped at the front side. Further, the edge of the ceiling 6 of the lid is overlapped outwardly so as to cover the edge of the ceiling 5 of the container (see FIG. 3). Furthermore, a stiffness 8 is provided at the front of the leg of the container to maintain strength.

The fire extinguisher storage box of the present invention is preferably manufactured by molding synthetic resin such as polyvinyl chloride, polyethylene, polystyrene, polyesters, polyamides, ABS, etc. The molding method is not particularly limited, but vacuum molding is preferred.

In the present invention, the lid also has a depth, in particular, the lid is deep on the ceiling side and shallow on the bottom side, so the joint surface between the container and the lid is inclined. This angle of inclination varies depending on the shape of the storage box, that is, the height and depth, and should be selected appropriately, but it can be determined depending on the depth of the lid on the ceiling. In this invention, the depth of the ceiling cover is 40 to 80% of the total depth.
It is. If this is less than 40%, it will be difficult to remove the fire extinguisher and the wall thickness of the back of the container will become thinner, which is inappropriate. On the other hand, if it exceeds 80%, the thickness of the front part of the lid will become thinner, and when the lid is opened, the center of gravity of the entire box will shift, resulting in poor balance.

Additionally, the depth of the bottom lid must be less than 10% of the total depth. This is because if this exceeds 10%, the fire extinguisher will not work stably.

Further, in the present invention, it is preferable that the ceiling part is not flat but sloped in the shape of a roof, and the container and lid are overlapped so that the joint part covers the container. By doing so, it prevents the intrusion of rainwater, makes it easy to release the mold when integrally molded, makes the wall thickness uniform, and increases strength. Further, it is preferable that the bottom part has a wave-shaped leg part and a firmness in the front part. This is because it is stronger than a flat bottom and prevents corrosion when the floor is placed on it.

[Effect of idea]

The present invention has the following effects.

(1) The ceiling of the lid is deep, so when the lid is opened, the top handle of the fire extinguisher is exposed, making it easy to remove the fire extinguisher.

(2) When vacuum forming the main body and lid of a fire extinguisher storage box using plastic, conventionally the main body was a box-shaped container and the lid was a flat plate with no depth. Molding had the disadvantage of thinning the back wall and reducing its strength, but with this invention, the depth of the ceiling is not extremely different between the main body and the lid (maximum 8:2), so Even when vacuum-formed from plastic, the back wall does not become thinner than conventional products and maintains its strength.
