Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the improvement of underground structures that are installed from under the floors of kitchens, living rooms, etc. to below the ground.

[Conventional technology]

In order to increase the storage capacity of conventional underfloor storage, which utilizes the underfloor space in kitchens, living rooms, etc., in recent years,
An underground storage-type underground structure that is deep enough to allow people to enter and work from below the floor to the ground, and can be accessed by opening a floor cover installed on the floor of the building. Various proposals have been made. Conventionally, in underfloor storage using the underfloor space, a lid plate that can be opened and closed is installed below the floor cover separately from the floor cover on the building floor, which prevents dust and odors from entering the underfloor storage. (Utility Model Application No. 49-114717), or a recess formed in an underfloor storage with ventilation holes that allows a perforated lid separate from the floor lid on the building floor to be stored. Accordingly, a perforated cover is used as a floor cover in place of the above-mentioned floor cover as needed to ventilate the inside of the underfloor storage (Utility Model Application No. 54-56933). Conventionally, in underground storages deep enough for people to enter and exit, a storage case and a lifting ladder are movably suspended below the entrance, and the size of the items stored in the underground storage and the storage case is A sheath, which can be used differently depending on the frequency of use (Japanese Patent Application Laid-Open No. 161167/1983), has been proposed.

[The problem that the idea aims to solve]

Regarding the above-mentioned conventional underfloor storage and underground storage, in the case of an underfloor storage that uses the space under the floor, there is relatively no problem because the depth of the storage itself is shallow and items can be taken in and out from the building floor. on the other hand,
If the underground storage is deep enough for a person to work inside, it may be troublesome to close the floor cover when entering the underground storage to work, so it is common practice to leave the floor cover open. There is a risk that children or other children may fall into the underground storage room.

In addition, in order to be able to work inside the underground storage even with the floor cover closed to prevent falling, there is a disadvantage that lighting equipment is required inside the underground storage.

However, if we simply apply the perforated lid of the conventional under-floor storage to this underground storage and make it possible to open and close it below the floor lid, we may be able to expect the effect of preventing the lid from falling, but the perforated lid will not be able to be opened or closed. It cannot be used as an effective storage space,
Furthermore, in the conventional storage case in the underground storage facility, if the storage case is located directly below the doorway on the floor, there is an inconvenience that no light can be brought in from inside the building.

In view of the above-mentioned disadvantages, it is an object of the present invention to provide an underground structure that prevents falling into the underground structure when the floor cover is open, allows daylight, and is convenient for storage.

[Means to solve the problem]

Below, the configuration of the present invention will be explained in the first example corresponding to the embodiment.
This will be explained using FIGS.

It is installed from under the floor of the kitchen etc. to below the ground.
In an underground structure in which a floor cover 11 is provided in an upper opening 1a connected to a floor opening 10a so as to be openable and closable, rails 3 are provided to run in parallel on both sides of the inside of the ceiling below the upper opening 1a. and install it,
An inner lid 2 shaped like a wire mesh and having a storage recess 2a is movably disposed on the rail 3 so as to open and close the upper opening 1a below the floor lid 11, as shown in FIG. The inner cover 2 automatically closes the upper opening 1a by means of a weight 5 connected to and suspended from the inner cover 2.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a vertical cross-sectional view showing an embodiment of the underground structure according to the present invention, which is placed from the floor to the ground. The peripheral edge is connected to the edge of a floor opening 10a formed in the floor 10 of the building, and 11 is connected to the edge of the floor opening 10a.
This is a floor cover that can be opened and closed to cover the floor. 2
is an inner cover located on the ceiling of the underground structure 1 below the floor cover 11 and provided to open and close the upper opening 1a of the underground structure 1; It is formed in the shape of a wire mesh as shown in the drawings to allow ventilation, and is also formed in a shape having a storage recess 2a so that small items can be stored and placed on the inner lid 2. As shown in FIGS. 1 and 2, this inner cover 2 slides from side to side on rails 3 that run parallel to both sides of the ceiling below the upper opening 1a of the underground structure 1. In addition to being movably mounted, a fourth
As shown in the figure, the inner lid 2 is attached to the inner lid 2 by means of a weight 5 or a spring, etc. so as to automatically close the upper opening as it moves from side to side. Note that 4 in Figure 4 is a pulley, and 6 in Figure 1 is a pulley.
is the staircase, 7 is the shelf, 8 is the handrail, and 9 is the foundation of the upper building. FIG. 3 is a perspective view showing a state where the floor cover 11 of the floor surface 10 is opened, and 12 is a handrail attached to the back side of the floor cover 11.

[Effect of idea]

As described above, the present invention involves installing rails running parallel to each other on both sides of the inside of the ceiling below the upper opening, and attaching to the rails an inner cover shaped like a wire mesh and having a storage recess above the lower part of the floor cover. An underground structure in which the opening is movably arranged so that it can be opened and closed, and the inner cover automatically closes the upper opening by means of a weight connected to and suspended from the inner cover. Even if a person enters an underground structure and leaves the floor cover open on the building floor, the inner cover placed below the floor cover automatically closes the upper opening. This has the great effect of preventing children, etc. from falling into the underground structure, and since this inner cover is shaped like a wire mesh and has a storage recess, the upper opening is blocked by the inner cover. It has the effect of not only allowing sunlight to enter the underground structure even when it is in a closed state, but also allowing storage of small items.
