DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage for a customer of propane gas (liquefied petroleum gas such as propane, butane, etc.) to store a propane cylinder and install it outdoors, and more particularly to a door structure thereof.

[0002]

2. Description of the Related Art Such a propane cylinder storage is installed for the purpose of, for example, protecting cylinders and incidental equipment from direct exposure to wind, rain, and sunlight. It is often a small place.

As a door structure of this type of conventional propane cylinder storage, there is known a door structure in which a door hooked on an opening is removed and opened as shown in Japanese Utility Model Publication No. 5-42320.

Further, as disclosed in Japanese Patent Application Laid-Open No. 6-174498, a door is known which opens and closes by linearly moving left and right like a sliding door with rails.

[0005] Further, there are known doors with shutters wound around the upper part and doors with double doors.

[0006]

The above-mentioned propane cylinder storage is normally opened and closed when a propane gas distributor replaces the propane cylinder.
Also, the propane gas storage is often installed by the propane gas dealer, and it is necessary to consider the easiness of the operation when replacing the propane gas cylinder.

[0007] The conventional door structure of the propane cylinder storage is such that the opening is greatly opened because the propane cylinder is easily replaced, and that the opened door does not hinder the replacement work.
Various things have been proposed in consideration of the fact that the door can be easily opened and closed.

However, if the door hooked on the opening is removed and opened, it is not easy to open and close the door.

In the case where the door moves linearly to the left and right and opens and closes, the opened door hinders the replacement operation.

[0010] In the case of a shutter wound around the upper part, it takes a long time to open and close the shutter, and it is not easy to open and close the door, and it is more expensive than other types.

Further, in the case of a door that opens in a double door, a large installation area is required for the open door, and the opened door hinders replacement work.

In view of the above, the present invention provides a propane cylinder storage which can be easily replaced when the propane cylinder is replaced by a door structure in which the opening is wide open and the opened door does not hinder the replacement operation, and the door is easily opened and closed. The purpose is to provide a warehouse.
