Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a structure for installing a rail under the floor for suspending four storage boxes so that they can travel freely.

[Background technology]

Conventional underfloor storage has a storage box suspended from a pair of rails arranged in a straight line, but such straight rails are difficult to use if you want to improve their usability. I was only able to hang two storage boxes. In other words, if you want to increase the number of storage boxes, you can hang three or four or more storage boxes on a straight rail, but in some cases, you may be able to hang the necessary storage boxes into a floor opening. In order to move it down, we had to move several storage boxes, which was inconvenient. Additionally, if multiple sets of underfloor storage units are installed, multiple rails must be installed under the floor, and multiple openings must be made in the floor, making the construction work more extensive. There was a problem. For this reason, a system has been devised in which two sets of rails are crossed so that four storage boxes can be suspended freely, but because the two sets of rails are crossed, The number of parts for rail materials is large, and along with this, the number of metal fittings used to connect the rail materials to each other and assemble the rails, and the number of metal fittings used to attach the assembled rails to the drawers and joists, are increased, making it difficult to assemble on-site. There were problems in that the construction was time-consuming, the work efficiency was low, and the metal fittings were expensive, making the cost expensive.

[Purpose of invention]

This invention was developed in view of the technical background described above, and its purpose is to create a system in which two sets of rails cross each other so that four storage boxes can be suspended. The object of the present invention is to simplify the assembly work of the rails on site and to reduce the cost of parts in the cross-type rails.

[Disclosure of invention]

The rail installation structure of the inventive underfloor storage is such that four central rail members 1 are connected in a rectangular ring shape by the lower part of a connecting fitting 2 to form a floor opening 3 directly below the floor opening, which is installed in line with the floor opening. A pair of end rail members 4 parallel to each other are extended from both ends of the center rail member 1 at right angles to the center rail member 1 to form storage box recessed portions 5 at four locations around the area directly below the floor opening 3. 4 is fixed to the main drawer 6 by a mounting fitting 13, and the upper part of the connecting fitting 2 is fixed to a joist 7 disposed on the main drawer 6. Therefore, the connecting fitting 2 for connecting the central rail materials 1 to assemble the floor opening 3 directly below the floor opening and the connecting fitting 2 for fixing the assembled rail A to the joist 7 are shared, and the rail A
The number of metal fittings required to assemble and install under the floor is reduced, which reduces the number of metal fittings that must be attached to the rail A, joist 7, etc. on site, and the installation of one connecting metal fitting 2 reduces the number of metal fittings required to assemble and install under the floor. The connection of the central rail material 1 and the installation to the joist 7 can be completed,
This can simplify on-site work.
Furthermore, the number of metal fittings can be reduced by sharing the connecting metal fittings, thereby making it possible to lower parts costs. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Reference numeral 1 denotes a central rail member having a substantially U-shaped cross section, and a plurality of freely rolling rollers 8 are pivotally supported at regular pitches on both sides of the interior, and the four central rail members 1 are connected to connecting metal fittings. 2 are connected in a rectangular ring shape so that the corners on the inner circumferential surface side butt against each other to form a floor opening 3 directly below the floor opening (not shown). As shown in FIG. 3, the connecting fitting 2 is bent into an L shape, with a cutout at the center of the upper half, and screw holes 9 are provided at both ends of the connecting fitting 2 in upper and lower stages. The ends of the central rail material 1 are connected by screws driven into the holes 9 in the lower half of the connecting metal fitting 2, and the edges of the notches 10 of the connecting metal fitting 2 are aligned with the top surface of the central rail material 1. This makes it easy to position the ends of the center rail material 1 when assembling the center rail material 1, and the protruding pieces 2a on both sides of the notch 10 protrude from the upper surface of the center rail material 1. Piece 2a
An upper hole 9 for fixing to the joist 7 is located at. Further, a pair of end rail members 4 are arranged at both ends of the center rail member 1 and are perpendicularly parallel to the center rail member 1, so that the corners of the center rail member 1 and the corners of the end rail members 4 are butted against each other. Corner fitting 1
A reinforcing rod 12 is arranged between the other ends of the end rail materials 4, and the ends of the end rail materials 4 are fitted into the reinforcing rods 12 and welded to connect the parallel end rail materials 4. A storage box retracting portion 5 is formed in the storage box 18 for retracting the storage box 18 under the floor. The center rail material 1 also has the same structure as the end rail material 4, and rollers 8 are pivotally supported inside at regular pitches, and the end surface of the end rail material 4 on the center rail material 1 side and both ends of the center rail material 1 The surfaces are each opened toward a space α created at a corner portion. The cross-shaped rail A for freely suspending the four storage boxes 18 is made by connecting the four central rail materials 1 and the eight end rail materials 4 with the connecting metal fittings 2 and the joining metal fittings 11, as described above. This cross-shaped rail A is installed under the floor as shown in FIGS.
It is fixed at Furthermore, center rail material 1
As shown in FIG. 2, the protruding piece 2a of the connecting fitting 2 connecting the central rail material 1 is attached to the side surface of the joist 7 above the main drawer 6 with screws, and is supported by the joist 7. In addition, a floor opening is opened in the floor directly above the floor opening 3 as described above, and the storage box 18
If you move it to 3 directly below the floor opening, storage box 1 will open.
Items stored in 8 can be taken in and out through the floor opening. Inside the rail A, there is a boat-shaped slider 1.
4 has been delivered and is placed on rollers 8 so as to be freely movable. As shown in FIGS. 4 and 6, the length of the slider 14 is longer than the pitch between the rollers 8 and the interval of the space α, so that it does not fall off the rail A even at the position of the space α. When the sliders 14 of other storage boxes 18 are retracted into the end rail material 4, they can move from the end rail material 4 to the center rail material 1 across the space α. A hanging fitting 16 is suspended from the slider 14 via a lower frame 15, and a flange 19 of a storage box 18 is inserted between the lower frame 15 and an upper frame 17 above it, and the storage box 18 is suspended from the hanging fitting 1.
It is placed on top of 6. Usually, each storage box 18 is stored in the storage box rear part 5, but if necessary, any storage box 18 can be slid along the rail A and stored in the storage box 3 directly below the floor opening.
You can move things to and take out stored items.

[Effect of the idea]

As described above, the present invention connects the four central rail materials in a square ring shape using the lower part of the connecting fitting to form the area directly below the floor opening that is installed in line with the floor opening, and parallel to each other from both ends of each central rail material. A pair of end rail materials are extended perpendicularly to the central rail material to form storage box retracted portions at four locations around the area directly below the floor opening, and each end rail material is fixed to the main drawer using mounting brackets, and the above-mentioned connecting brackets are Since the upper part of the rail is fixed to the joists installed above the main drawer, we will use connecting fittings to connect the central rail materials and assemble the area directly below the floor opening, and to fix the assembled rails to the joists. The number of metal fittings required to assemble and install the rails under the floor is reduced, and the number of metal fittings that must be attached to the rails, joists, etc. on site is reduced. This has the advantage that the connection of the central rail material and the installation to the joist can be completed by installing one connection fitting, which simplifies the work on site. Furthermore, the number of metal fittings can be reduced by sharing the connecting metal fittings, thereby making it possible to lower parts costs.
