Description

[Detailed Description of the Invention] This invention relates to an underfloor storage device used when storing articles using an underfloor space.

Generally, an underfloor storage device is configured such that a support shaft is mounted on the ground in an underfloor space that communicates with an opening provided in the floor, and a receiving plate is rotatably supported around this support shaft. Conventionally, in order to rotatably support the receiving plate, the two have been connected via a bearing member.

However, conventional underfloor storage devices that use bearing members have a complicated structure, and because various items are placed casually on the receiving plate of the storage device, unbalanced loads are often applied. However, this has the disadvantage that an excessive load is applied to the bearing portion, and the receiving plate easily tilts.

The present invention was made to eliminate these drawbacks, and has a simple structure as a whole.
Further, it is an object of the present invention to provide an underfloor storage device that rotates smoothly and is free from problems such as easy tilting of the receiving plate.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figures 1 and 2 show the underfloor storage device of this invention, and in the figures, 1 is a support shaft, for example, a base 1a that projects horizontally from the entire circumference of its lower end.
Therefore, the support plate 2 is arranged in a substantially vertical position, and a support plate 2 is provided at a substantially intermediate position.

In this embodiment, the support plate 2 is formed into a disk shape, is arranged and fixed horizontally at an intermediate position of the support shaft 1, and is fixed at the free end of the support plate 2, that is, the outer circumference in this embodiment. Nearby, a wheel 3 is mounted by a bracket 4 for vertical rotation.

Reference numeral 5 denotes a receiving plate for storing the article A, which is circular in plan view and has a hole 5a in its center.
At the same time, a cylindrical bent part 5b is formed downward from the peripheral edge of this hole 5a, and
It is adapted to be detachably and rotatably attached to the support shaft 1 via the support shaft 1.

At this time, the back surface of the receiving plate 5 is held in a state where it is supported by the wheels 3 of the supporting plate 2, so that even if an uneven load is placed on the receiving plate 5, the receiving plate 5 does not tilt. , as the receiving plate 5 rotates, the wheels 3
Since it rotates vertically, the receiving plate 5 rotates smoothly.

In addition, although the case where the receiving plate 5 is circular is demonstrated in the said Example, it is not limited to a circular thing, The shape is arbitrary, for example, square shape.

FIG. 3 is a plan view showing a second embodiment of this invention, in which the receiving plate 5 is formed of a plurality of receiving plates 5', 5', . . . .

In this way, the receiving plate 5 is connected to a plurality of receiving plates 5', 5'...
By forming the container, for example, it is advantageous in terms of transportation or inventory control, and it can also be easily assembled.

FIG. 4 is a side sectional view showing the usage state of the underfloor storage device according to this invention, in which the support shaft 1 is erected on the ground 9 in the underfloor space 8 communicating with the opening 7 provided in the floor 6. Then, by the wheels 3 of the support plate 2 provided on the support shaft 1, the receiving plate 5 is rotatably supported in a substantially horizontal direction, so that a part of the receiving plate 5 is positioned directly below the opening 7. This is a case where an underfloor storage device is formed. In this case, a lid 10, which itself constitutes a part of the floor 6, is attached to the opening 7 so as to be openable and closable.

Further, a support 11 is erected on the center of rotation of the receiving plate 5, and the upper end of the support 11 is supported by a bracket 12 attached to a floor base material 6' such as a floor joist or the like. By doing so, it is possible to completely prevent the receiving plate 5 from tilting due to an uneven load.

According to the underfloor storage device configured as described above, many articles A can be stored on the concentric circumference of the receiving plate 5 through the opening 7, and the articles A can be easily taken in and taken out through the opening 7. It can be done.

As is clear from the above description, according to the underfloor storage device according to the present invention, the receiving plate is rotatably fitted to the support shaft that is erected almost vertically, and the receiving plate is attached to the supporting plate. Since it is held by wheels, bearings and the like are not required, and the overall structure is simple, and even if the receiving plate receives an uneven load, it will not easily tilt or wobble.

Moreover, since the back surface of the receiving plate is held by wheels that can rotate vertically, the rotating of the receiving plate can be made smooth.
