Description

[Detailed description of the invention] This invention is based on the idea that a horizontally rotatable article holder installed in the underfloor space that communicates with an opening in the floor can store many articles through the opening. This relates to a rotating under-floor storage device that allows for easy installation in under-floor spaces where workability is difficult, especially by configuring all the parts attached around the rotating shaft to be removable. In addition, the purpose is to facilitate maintenance during inventory and transportation.

Examples of this invention will be described below based on the drawings.

Figures 1 to 4 show an embodiment of the rotary underfloor storage device of this invention. In the figures, 1 is a floor and 2 is a hatch. It consists of a substantially rectangular outer frame 4 that is fitted and fixed inside, and an openable and closable lid body 6 that is fitted with a lid plate inside an inner frame 5 that is fitted inside this outer frame 4. There is.

Further, a rotating shaft 1 is attached to a bearing 8 installed on the ground A in an underfloor space 7 communicating with the opening 3 and a bracket 9 attached to a floor base 1' such as a joist located around the opening 3.
In this case, a hollow upper shaft 10a fixed to the bracket 9 and a hollow upper shaft 10a fixed to the bracket 9 and the upper shaft l
This rotary shaft 10 is separated from a hollow lower shaft body 10b that is slidably and rotatably fitted in the lower part of the ea, and only a part of it, that is, the lower shaft body 10b, is rotatable in the horizontal direction, Moreover, it can be expanded and contracted according to the distance between the floor part 1 and the ground A.

Note that the upper shaft body 10a and the lower shaft body 10b are connected, for example, in a spline shape so that only sliding is possible, and the upper shaft body 10a
The same effect can be obtained even if the bracket 9 rotatably supports the bracket 9.

Alternatively, the rotating shaft 10 may be formed with a single hollow shaft.

A plurality of slits 11, 11, .
... are bored along the axial direction.

Each support arm 12 protruding from the rotating shaft 10 through the slit 11 is attached to a side end portion of the support arm 12, which is inserted through the slit 11 and comes into contact with the inner surface 10b' of the lower shaft body 10b. The first locking piece 12a and the second locking piece 12b that abuts against the outer surface 10b'' side of the lower shaft body 10b are provided to protrude facing each other in the vertical direction, as shown in FIG. As shown, the first locking piece 12 inserted through the slit 11
a comes into contact with the inner surface 10b' of the lower shaft 10b, and the second locking piece 12b contacts the outer surface 10 of the lower shaft 10b.
b", the support arm 12 removably projects radially from the lower shaft 10b.

On the other hand, at the upper end of the support arm 12 there is a plate 14 which will be described later.
A member 17 is removably attached to hold the holder.

In this installation, the member 17 has flange-shaped receiver portions 17b, 17b protruding outward from the lower end of an inverted U-shaped base 17a, and the support arm 12 is held between the base 17a. It is detachably attached to the upper end of the support arm 12.

The receiving plate 14 is a plate-like body formed into a fan shape in plan view, and a bent piece 14b is protruded from the lower surface of the end thereof. and are held with their side edges in contact with each other (see Fig. 4).

Therefore, in order to assemble the rotary underfloor storage device of this embodiment, the support arm 12 is attached to the lower shaft body 10b of the rotating shaft 10, and then the mounting member 17 is attached to the upper end of this support arm 12. This attachment can be accomplished by using the member 17 as a supporting member and sequentially arranging the receiving plates 14 to form the article receiving part 15 extending around the rotating shaft 10.

The article receiving section 15, a part of which is located directly below the opening 3, is rotatably displaced in the horizontal direction together with the rotation shaft 10, and stores or takes out the article B inserted through the opening 3 into its upper part. That's what I do.

Note that 14b is a recess provided in the plate 14 for reinforcement.

Figure 5 shows the rotating shaft 10 and support arm 12 in this invention.
Another attachment of the support arm 12 is shown as an example, and the attachment of the support arm 12 is a case where the condition is made more solid.

That is, the support arm 12 is attached to the part of the lower shaft body 10b that engages with the second locking piece 12b provided at the side end.
A locking slit 16 into which the second locking piece 12b is fitted is provided, and the second locking piece 12b is inserted into the locking slit 16.
This is a case in which the support arm 12 is firmly attached without swinging from side to side by fitting them together.

As explained above, in the rotary underfloor storage device of this invention, the rotating shaft 10, the support arm 12, and the support plate 14 arranged in the underfloor space 7 are formed separately, and each part is attached Since no fixing devices such as screws are used at all, it can be easily assembled even in the underfloor space 7 where workability is relatively poor. Since it is supported by the member 17, there is no need for special work such as attaching the support arm 12 to the support part of the plate 14, which reduces manufacturing costs and allows each component to be stored separately. Therefore, it has excellent effects such as extremely advantageous maintenance during inventory or transportation.
