Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underfloor storage device that can store many items by effectively utilizing the space under the floor.

That is, the gist of the present invention is to form a hatch having a lid for opening and closing the gate provided in the floor, and to connect the back surface of the floor and the ground in the underfloor space at the bottom of the hatch. Of the two rotating struts whose length can be adjusted according to the distance, only the lower member is horizontally rotatable and is attached to the lower member (lower strut) of the rotary strut. The article receiving portion is formed by a plurality of receiving plates that are stretched around the lower support of the rotating support via a plurality of supporting arms that protrude radially from the rotating support, and a part of the receiving plate is located directly below the closing opening. To provide an underfloor storage device characterized in that an article receiving section is horizontally horizontally displaced together with a lower support of a rotating column, and articles can be stored or taken in and out through a hatch on the article receiving section. That is.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a side sectional view showing an example of the underfloor storage device of the present invention. In the figure, 1 is a floor section, and 2 is a hatch provided in this floor section 1. An openable and closable lid body 6 is made up of a substantially rectangular outer frame 4 which is iron-fixed within the gate 3 provided in 1, and a lid plate attached to an inner frame 5 which is fitted inside the outer frame 4. It is made up of.

Further, a rotary support 9 is vertically installed in the underfloor space 7 where the closing opening 3 and the lotus are connected. This rotating support 9 has a placket 1 at its upper end.
1, the upper end of the upper support 9W is fixed to the floor base material wing, such as a floor joist, located around the opening 3, so that the upper end thereof can move vertically and rotatably, and the lower end The lower support 9a is rotatably connected to the recess 8a of the bearing 8 fixed to the ground A via the rotor i8.
The upper end portions are supported by the upper support columns 9M and are rotatable. This lower support column 9a has a plurality of support arms 12,
12... are each radially engaged, and a plurality of 13 receiving plates 13... are connected via these support arms 12.
. . . The keys are provided together and cooperate with each other to form an article receiving portion 14 that extends around the rotating support 9. And open□
By rotating the article receiving section 14, a part of which is located directly below the hatch 2, in the horizontal direction together with the lower support a, the article B can be stored or taken out through the hatch 2 above. . Note that the rotational performance of the lower support vine a should be within the range in which the article B placed on the article receiving portion 14 can rotate under the maximum load. Rather, it is better to provide a means to control the rotation.For example, this rotation control means may include increasing the contact area between the bearing flea and the rotor turtle Q as much as possible. Alternatively, a brake machine (not shown) may be provided.On the other hand, the support arm 12 may be separate from the rotating support g in consideration of inventory management, ease of transportation, and ease of installation. In this case, in this invention, a locking piece 12a is provided at the upper end of the attachment side end surface of the support arm 12, and the locking piece 12a is attached to the inner surface ga' of the lower support column ga, the tip of which is formed in a hollow shape. In addition, a protruding single wing 2b is formed at the lower part of the attachment side end face to be in contact with the outer surface 9a of the lower support ga, and the engagement slit 2b provided in the lower branch 9a is inserted into the lower part 9a. After inserting the locking piece 12a into the
By loosening the locking piece tatami 2a on the inner surface gak of the lower support column 9a and the support piece 2b on the outer surface ga'', the support arm 2 is fixed radially from the lower support column 9a. It has become.

Further, on the upper end surface of the support arm 12, locking claw angles 2c and hooks 2d are protruded at appropriately spaced locations, and each receiving plate 13 is fixedly fixed by the locking claw necks 2c and 20. It is supposed to be done. In other words, the locking claws 12c and the roof 2d protruding from each location are bent and raised in opposite directions from positions close to each other.
The bent end piece 13a of the receiving plate 13 is held in between, and the receiving plate 13 is attached to the article receiving part 1 around the lower support column ga.
4 is formed. As another means for attaching the receiving plate 13 to the support arm turtle 2, as shown in FIG. flange portion 17a,
It is also conceivable that the end bent piece 13a of the receiving plate 13 is bent over the receiving plate 17a. Note that the package 3M is a reinforcing recess provided in the receiving plate turtle 3. The underfloor storage device of the present invention configured as described above includes a hatch 2 with a lid 6 attached in an openable and closable manner within an outer frame 4 which is iron-fixed within a gate 3 provided on a floor 1; The lower strut ga is rotatably supported in the horizontal direction by a bearing support installed on the ground A in the underfloor space 7 through which the opening 3 of 2 is conveyed, and an upper strut gb whose upper end is fixed to the floor base. Rotating strut 9 with
, a plurality of support arms 12 that are radially engaged from the lower support column ga, and a plurality of support arms 12 that are arranged side by side on these support arms and that cooperate with each other to form an article receiving part that extends around the rotating support column g. By rotating and displacing the article receiving part 14, a part of which is located directly below the closing opening 3 of the hatch 2, together with the lower support 9a in the horizontal direction, The article B can be stored or taken out through the hatch 2 on the hatch 2. Therefore, the article B can be stored concentrically within the range that can be stored from the opening 3 of the hatch 2. , an excellent effect can be obtained in that many articles B can be stored using the space under the floor.
According to this invention, the upper end of the lower support column ga, which is the substantial rotational axis of the article receiving tower 4, is supported by the upper support column 9M, and this upper support column gb has a role as a bearing. Therefore, even if an unbalanced load is applied, the lower support column does not wobble or tilt and can always maintain smooth rotation.
The upper end of the upper support 9b does not need to be rotatably supported;
It is only necessary to fix it to the floor base plate 1 through the bracket 11, and the lower end of the lower support ga can be iron-coupled simply by placing it in the recess 8a of the bearing 8, making the construction easy. Moreover, since the upper support 9b and the lower support ga are designed to be movable in the vertical direction relative to each other, the lower end of the lower support 9a is iron-coupled to the bearing 8, and the upper end of the upper support 9b is connected to the floor base material 1.
By fixing to ', the length is automatically adjusted according to the distance between the lower surface of the floor part 1 and the ground A, so it can be used over a wide range without being affected by the distance. Since the iron parts of the upper support 9b and the lower support 9a do not need to be fixed with screws or the like, the installation work can be made more efficient. In addition, the rotating column 9, the support arm 12, and the receiving plate 13, which are the constituent members, can be stored separately, and the rotating column 9 can be reduced in size, which is advantageous for inventory management and transportation. Moreover, since each member can be easily attached, it has excellent effects such as being able to be easily attached even in a place where workability is poor, such as under the floor, and its utility value is remarkable.
