Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underfloor storage device, and more particularly to an underfloor storage device in which a side wall plate is provided at the periphery of a top plate and a bottom plate to form a bag body.

Conventional underfloor storage devices typically have an opening in the floor, a box with an upper opening is suspended under the floor, and the opening is opened and closed with a lid.

However, with this type of underfloor storage device, the box body is pre-molded from synthetic resin, etc.
If it is larger than the floor opening, it cannot be carried under the floor as it is. For this purpose, the box is made somewhat smaller than the opening on the floor, and is carried from above the floor through this opening to the underfloor, and the upper edge of the box is secured to the frame material fixed to the periphery of the opening. It is hung under the floor. According to this, not only the box cannot be firmly attached, but also a box larger than the floor opening cannot be suspended, making it impossible to secure a sufficient storage volume. On the other hand, in order to obtain a sufficiently large storage volume, it is sufficient to make the floor opening large and suspend a box that matches that size, but if the floor opening is made large, the rigidity around the opening decreases, so floor joists etc. The cross section of the opening/closing lid body had to be made large, and the opening/closing lid body itself had to be made robust.

The present invention was developed in view of the above points, and it is extremely easy to place the bag in the floor opening under the floor, and also allows the bag to be integrally attached to the joists and the subfloor surface. This provides a useful underfloor storage device.

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a partially omitted perspective view of an underfloor storage device according to the present invention. Reference numeral 1 denotes a floor joist, and this floor joist is placed on a large joist (not shown). Reference numeral 2 denotes a floor opening, and a peripheral frame 3 made of metal or synthetic resin is attached to the peripheral edge of this opening 2. This surrounding frame 3
The peripheral edge 41 of the opening/closing lid 4 is placed on the stepped portion to close the floor opening 2.

Reference numeral 5 designates the upper surface plate of the bag body X of the storage device according to the present invention, which is a flexible sheet material having an area larger than the floor opening 2, and has a peripheral frame approximately in the center that communicates with the floor opening 2. An opening section 51 is provided for attachment to 3.

The bottom plate 6 is made of a flexible sheet material having substantially the same shape as the top plate 5. Side wall plates 7, 7, 7, 7 made of flexible sheet material are provided in the shape of a bag between the peripheral edge 52 of the top surface 5 and the peripheral edge 61 of the bottom surface 6. The peripheral portions 52, 61 and the side wall plates 7, 7, 7, 7 are joined to each other by pressure bonding or welding using an adhesive. The joining of the side wall plates 7, 7 at the corners of the bag body is also carried out by the same means as described above.

As described above, the top plate 5, the bottom plate 6, and the side wall plate 7 between them constitute one bag body. Further, an upper lug piece 53 is provided on the peripheral edge part 52 of the top plate 5, and a bottom lug piece 62 is provided on the peripheral edge part 61 of the bottom plate 6, respectively. The upper ear piece 53 and the bottom ear piece 62 are provided to extend outward from the side wall plate 7, and fixing holes 54, 54..., 63, 63... is drilled.

On the other hand, reinforcing ribs 71, 71, . . . are attached in the vertical direction to the side wall plates 7, 7, 7, 7 in order to make the side wall plates self-supporting. The reinforcing ribs 71, 71, . . . are formed by attaching a vertically long bag to the side wall plate 7, and inserting a reinforcing core into the bag. The reinforcing ribs may be formed by forming vertically long thick portions at required locations on the side wall plate 7, or may be formed by pasting corrugated plates on the side wall plate 7.

Further, a drainage hole 72 is provided near the bottom of the bag body X to discharge water remaining inside the bag body to the outside. A through hole 8 is provided for ventilating stagnant air within the bag body X. There are usually two through holes 8, one each on the diagonal of the plane of the bag body X.
Each is provided.

Next, the installation state of the storage device of the present invention will be explained in detail with reference to the longitudinal sectional view of FIG.

First, a rectangular opening 2 is provided on the floor surface where the storage device will be installed. At this time, the floor opening 2 is provided between the joists 1, 1, . . . without cutting the joists 1 themselves.

A peripheral frame 3 made of extruded aluminum, synthetic resin, or the like is arranged around the periphery of the floor opening 2.

Furthermore, the bag body X is inserted into the underfloor through this floor opening 2. Since the bag body A is entirely made of a flexible sheet material, the bag body X is constructed by inserting the bag body X in a folded state under the floor and then expanding it inside the floor.

Thereafter, the opening section 51 provided on the top plate 1 of the bag body A is fixed to the locking piece 31 of the peripheral frame 3 via a fastening fitting 32 such as a nut. The bag body X can stand on its own by the reinforcing ribs 71 of the side wall plate 7 just by fixing this opening section 51, but nails, etc. Attach the upper ear piece 53 and hang the bag body A, and then fix the bag body X to the subfloor surface GL by driving the anchors 64, 64 into the fastening holes 63, 63, . . . provided in the bottom ear piece 62. I can do it.

Finally, the peripheral edge 41 of the opening/closing lid 4 is placed on the stepped portion of the peripheral frame 3 attached to the opening 2, thereby completing the installation of the underfloor storage device according to the present invention.

FIG. 3 shows how the bag X and the peripheral frame 3 are attached when the fixing hole 54 provided in the top plate 5 of the bag X and the mounting joist 11 match and when they do not match. FIG. 3A shows a fixing hole 54 provided in the top plate 5.
is placed on the lower surface of the mounting joist 11,
The locking piece 31 in this case is designed to make the floor opening 2, which is provided by vertically extending the lower part of the peripheral frame 3 in the direction below the floor, sufficiently large. Further, FIG. 3B shows a case where the fixing hole 54 is located outward from the mounting joist 11. At this time, since the bag body X is entirely made of a flexible sheet material, using the locking piece 31 installed laterally inward of the floor opening 2, the locking hole 54 is attached to the lower surface position of the joist 11. You can pull up to. As a result, the top plate 5 of the bag body X can be fixed to the mounting joist 11 via the fastening hole 54.

As explained above, the underfloor storage device according to the present invention has a bag body made of a flexible sheet material, so it can be transported underground in a folded state, and the bag body can be transported underground between the joist and the subfloor surface. Since it is integrally attached to the floor, the space under the floor is effectively used and the storage capacity is large. Moreover, since this storage device can be packed compactly, costs associated with shipping, transportation to the site, and inventory can be reduced, resulting in extremely high technical and economical effects.
