Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an underfloor storage, particularly an underfloor storage in which the lid plate that is released when taking out stored items can stand on its own.

[Conventional technology]

Conventionally, underfloor storage has generally been constructed by placing a lid plate on a frame attached to the periphery of an opening in the floor to cover the opening and locking a box provided under the floor. However, when taking out stored items, the released cover plate must be grasped with one hand or the cover plate must be completely removed from the opening, and this relatively heavy cover plate must be grasped or removed. A considerable amount of effort was required to move it.

Therefore, as shown in Fig. 6, a device was devised in which the released lid plate was locked to a frame attached to the periphery of an opening in the floor surface so that it could stand on its own. .

[Problem that the invention attempts to solve]

However, the above-mentioned underfloor storage is designed so that the released lid plate can fit into and be locked in the groove formed between the hanging piece of the edge frame and the lid plate support piece. When closing the lid plate, the lid plate must be lifted once, so the opening/closing operation of the lid plate is not necessarily satisfactory.

This invention was devised to eliminate the drawbacks of the above-mentioned conventional products, and aims to provide an underfloor storage that can be opened and closed simply by rotating the lid plate.

[Means to solve the problem]

This idea was devised in view of the above, and a locking protrusion facing outward is provided around one side of the upper horizontal piece of the rim body, which has a U-shaped cross section, as a cover plate for shielding the opening. A frame is attached to the periphery of the lid body, and one side of the upper horizontal piece placed on the periphery of the opening is used as a rim frame attached to the periphery of the opening. The lower horizontal piece is bent upward to form a hanging piece, and the tip thereof is extended in the horizontal direction to form a lower horizontal piece, and the tip of the lower horizontal piece is raised upward and the tip is extended in the horizontal direction. to form a cover plate support piece, and attach an engaging protrusion hanging from one side of the cover plate support piece toward one side so that the distance between the tip thereof and the hanging piece is smaller than the height of the rim body. The problem was solved by using a protruding structure.

〔Example〕

Embodiments of this invention shown in the drawings will be described below. FIG. 1 is a partially cutaway sectional view showing one embodiment of this invention, and FIGS. 2 and 3 are partially cutaway views showing the same in use. The cut-away sectional views, FIGS. 4 and 5 are sectional views of the edge frame and cover plate, which are the same members as above, and A in the figure
is the floor surface, B is a rectangular opening opened in the floor surface A, and C is a frame made of aluminum attached to the periphery of the opening B;
One side of the upper horizontal piece 6 placed on the peripheral edge of the upper horizontal piece 6 is bent downward to form a hanging piece 7, and its tip extends horizontally to form a lower horizontal piece 8. A cover plate support piece 9 is formed by raising the tip of the piece 8 upward and extending the tip in the horizontal direction, and an engaging protrusion is provided on one side of the cover plate support piece 9 toward the hanging piece 7 side. The piece 10 is protruded so that the distance X between the tip and the hanging piece 7 is smaller than the height Y of the rim body 1, which will be described later, and D is placed on the rim frame C. The rim is a cover plate for shielding an opening B, which is formed by a rim main body 1 having a U-shaped cross section and a locking protrusion 3 extending outward on one side of the upper horizontal piece 2 of the rim main body 1. 4 is attached to the periphery of the lid main body 5, and E is locked to a locking piece 11 having an L-shaped cross section and extending to the other side of the lid support piece 9 of the edge frame C. The box is made of synthetic resin such as polypropylene.

[Effect of idea]

Since the underfloor storage of this invention has the above-mentioned configuration, when using it, first, as shown in Figure 2, cover plate D
By lifting a handle (not shown) provided on one edge side a and rotating the cover plate D using the other edge side b, which is opposite to the one edge side a, as a fulcrum, the lid plate D can be opened. While the locking protrusion 3 on the other edge side b slides downward along the inner surface of the hanging piece 7 of the edge frame C, the cover plate D slides along the inner surface of the hanging piece 7 of the edge frame C. By standing vertically and continuing to rotate the cover plate D, the locking protrusion 3 moves to the engagement protrusion 10 as shown in FIG.
The cover plate D is erected in a slightly inclined state due to the load of the cover plate D, using the base end of the upper horizontal piece 6 as a fulcrum. On the other hand, when the cover plate D is to be closed, the cover plate D is attached to the opening B by rotating the cover plate D in the opposite direction using the other side edge b as a fulcrum.

Therefore, the underfloor storage of this invention is opened and closed by rotating the cover plate D using the other edge side b of the cover plate D as a fulcrum, so that workability is improved compared to conventional products. , furthermore, the released lid plate D is the lid plate D
Because the legs are slightly tilted due to the load, it is easy to take in and take out stored items, and safety is also improved.

Claims (1)

[Scope of utility model registration request] This underfloor storage is constructed by placing a lid plate D that shields the opening B on a frame C attached to the periphery of an opening B opened on the floor surface A, and locking a box E provided under the floor. In this case, a rim 4 having a locking protrusion 3 extending outward on one side of the upper horizontal piece 2 of the rim main body 1 having a U-shaped cross section is attached to the periphery of the lid main body 5. One side of the upper horizontal piece 6 placed on the periphery of the opening B is bent downward to form a hanging piece 7, and the tip thereof is extended horizontally to form a lower part. A horizontal piece 8 is formed, and the tip of the lower horizontal piece 8 is raised upward, and the tip extends horizontally to form a cover plate support piece 9, and on one side of the cover plate support piece 9. Engagement protrusion 1 facing the hanging piece 7 side
This underfloor storage is made up of an edge frame C which is formed by protruding a rim frame C such that a distance X between its tip and the hanging piece 7 is smaller than the height Y of the rim body 1.
