Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to the structure of a cross-shaped rail installed under the floor for freely suspending four storage boxes.

[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 other rail intersecting each other obstructs the movement of the storage box in two places, making the race structure complicated, and the number of rail parts increasing, making it difficult to connect these many rail parts at the site. The problem was that each rail had to be connected one by one using hardware, making the rail assembly work complicated and taking a long time.

[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. To facilitate the assembly of a cross-type rail on site.

[Disclosure of invention]

The structure of the rail of the inventive underfloor storage is such that a reinforcing rod 2 is attached between one end of a pair of end rail members 1 that are parallel to each other, and a central rail member 3 is installed at right angles between the other ends of both end rail members 1. The end of the end rail material 1 on the inner circumferential surface side and the end of the inner circumferential surface side of the center rail material 3 are butted together, and the end of the end rail material 1 and the end of the center rail material 3 are connected using the corner joining fittings 7. The rail blocks 4 of the factory-produced product are constructed by connecting the parts, and the central rail materials 3 of the four rail blocks 4 are assembled in a square shape, and the ends of the central rail materials 3 on the outer peripheral surface side are butted against each other. In this way, the end rail members 1 and the center rail members 3 arranged in a straight line are connected at the field site using the corner connecting fittings 5, and the end rail members 1 and the center rail member 3 are connected through the space α. Therefore, when constructing an underfloor storage on-site, the rail construction can be easily completed on-site by simply assembling the semi-finished rail blocks 4 at the factory, which simplifies the construction. This makes it possible to shorten construction time. Moreover, by suspending the storage boxes 15 so that they can move freely with the slider 13 that is longer than the width of the space α, the four storage boxes 15 are suspended from the rail 8, and the storage boxes 15 are alternately placed in the center of the rail 8 located under the floor opening. This makes it possible to move to. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. 1 is an end rail material having a substantially U-shaped cross section, and a plurality of freely rolling rollers 6 are pivotally supported at regular pitches on both sides of the inside; 3 is an end rail material having the same structure as the end rail material 1; It is a center rail material, and 2 is a square groove-shaped reinforcing rod 2. One end of each of the pair of end rail members 1 arranged in parallel is fitted into both ends of the reinforcing rail 2 and fixed to the reinforcing rail 2 by welding, and a center rail is provided between the other ends of the end rail members 1. The rail blocks 4 are arranged at right angles, and the end of the end rail material 1 on the inner peripheral surface side and the end of the inner peripheral surface of the center rail material 3 are butted against each other and connected by a corner joining fitting 7 to form a rail block 4. The end surface of the end rail material 1 on the center rail material 3 side and both end surfaces of the center rail material 3 are each opened toward a space α generated at the corner portion. This rail block 4 is a factory product that is assembled in one piece at a factory and shipped to the site. A cross-shaped rail 8 for freely suspending the four storage boxes 15 is assembled by connecting four rail blocks 4 on site. That is, the four rail blocks 4 are arranged in a cross shape as shown in FIG. are connected by an L-shaped connecting fitting 5, thereby forming a floor opening 9 directly below the floor opening (not shown), which is surrounded by the central rail material 3 at the center of the rail 8 and is positioned directly below the floor opening (not shown). Storage box retreat portions 10 located under the floor are formed at four locations around the storage box. As shown in FIGS. 3 and 4, this cross-shaped rail 8 is installed under the floor by fixing the end rail material 1 to the drawer 12 with a mounting fitting 11. The center rail material 3 is supported by the end rail material 1 via the joining metal fittings 7, but the center rail material 3 may also be fixed to the main drawer 12 or the like with appropriate mounting metal fittings. Further, above the floor opening 9, a floor opening is opened in the floor as described above, and when the storage box 15 is moved to the floor 9 directly below the floor opening, items stored in the storage box 15 can be taken in and out through the floor opening. It's summery. Inside the rail 8 is a boat-shaped slider 1.
3 has been delivered and is placed on rollers 6 so that it can run freely. As shown in FIGS. 3 and 5, the length of the slider 13 is longer than the pitch between the rollers 6 and the interval of the space α, so that it does not fall off the rail 8 even at the position of the space α. When the sliders 13 of the other storage boxes 15 are retracted into the end rail material 1, they can move from the end rail material 1 to the center rail material 3 across the space α. A storage box 15 is placed on the hanging fitting 14 hanging from the slider 13, and each storage box 15 is usually stored in the storage box rear part 10, but if necessary, it can be placed in any storage box. 15 can be slid along the rail 8 and moved to a position 9 directly below the floor opening, allowing storage items to be taken in and taken out.

[Effect of the idea]

As described above, in this invention, a reinforcing rod is attached between one end of a pair of end rail materials that are parallel to each other, a central rail material is arranged at right angles between the other ends of both end rail materials, and the inside of the end rail materials is A factory-produced rail block is created by butting the circumference side edge and the inner circumference side edge of the center rail material, and connecting the end of the end rail material and the end of the center rail material using the corner joining fittings. The center rails of the four rail blocks were assembled in a rectangular shape, and the outer edges of the center rails were butted against each other, and connected on site using corner fittings to form a straight line. Since the side-by-side end rail materials and center rail materials are connected through a space, when constructing an underfloor storage on-site, it is easy to assemble semi-finished rail blocks at the factory in advance on-site. This system has the advantage that rail construction can be completed on-site, reducing the number of parts assembled on-site, simplifying rail installation, and shortening on-site construction time.
