The main body is formed by providing a support portion 19 having a U-shaped cross section. The contact piece 3a has a connecting plate 7 described later.
A positioning hole 9 with which the positioning protrusion 8 is engaged is formed. The support portion 19 includes an upper piece 20 integrally projecting laterally from the contact piece 3a, a load receiving piece 13 integrally projecting downward from the upper piece 20, and a load receiving piece 13. And a mounting piece 14 provided at the lower part. Upper piece 2
A pair of ridges 12a are provided on the upper surface of O so as to oppose each other, and a running groove 12 in which the runner 11 runs is formed between the opposing ridges 12a. Load receiving piece 13
Is located directly below the center of the running groove 12 in which the runner 11 runs, and is stored in the underfloor storage 4 received in the running groove 12.
Can be received in a well-balanced manner without escaping in the other direction. A protruding piece 21 is protruded from the inner end of the mounting piece 14 so as to face a protruding piece 21 protruding downward from the lower end of the contact piece 3a.
Further, a protruding piece 22 is protruded from the mounting piece 14 and the upper piece 20 so as to be located inside each protruding piece 21. A groove 6a having a predetermined width is provided between the projecting piece 21 and the projecting piece 22.
Are provided, and the connecting groove 6 is formed by the groove 6a. A stopper 23 as shown in FIG. 6 or a connection plate 5 as shown in FIG. 7 is fitted into the connection groove 6 so that the rail 3 is fixed to the support arm 2 by the stopper 23. The rails 3 arranged adjacent to each other by the connection plate 5 are connected to each other.

The stopper 23 is formed of a thin plate material.
The connection groove 6 can be slidably fitted into the connection groove 6, and a screw hole 23 a is formed in the center at a position corresponding to the position of the opening 6 b of the connection groove 6.
The attachment of the rail 3 to the support arm 2 by the stopper 23 is performed by inserting the stopper 23 into the connecting groove 6 as shown in FIG.
And the fixing tool 10 is screwed into the screw hole 23a of the stopper 23 via the arm body 2a from the outside of the arm body 2a of the support arm 2 to be connected and fixed to the support arm 2. In other words, the support arm 2 and the rail 3 are connected to each other by tightening the fixing tool 10 and clamping the protrusion 21 of the rail 3 between the arm body 2a of the support arm 2 and the stopper 23.

As shown in FIG. 7, the connection plate 5 is formed in a strip shape, and can be slidably fitted into the connection groove 6 like the stopper 23, and is connected to both ends. Is provided with a screw hole 5a. When connecting the rails 3 using the connection plate 5, FIG.
The connecting plate 7 as shown in FIG.

The connecting plate 7 is formed in a substantially L-shape. A main body is formed by projecting a support piece 25 at a lower end of a plate body 7a formed of a thin plate material in a direction orthogonal to the plate body 7a. ing. Screw holes 7b are drilled at both lower ends of the plate body 7a, and positioning projections 8 are projected above the screw holes 7b. The positioning projection 8 is formed by partially cutting and raising the plate body 7a as shown in FIG. Here, the positioning protrusion 8
May be formed by providing a projection (not shown) at an appropriate position on the plate body 7a.

Thus, the adjacent rails 3
The connection plate 5 is fitted into the connection groove 6 of the support piece 2.
5 is brought into contact with the lower surface of the mounting piece 14 so that each rail 3
The connecting plate 7 is arranged at the abutting portion of the connecting plate 7, and the connecting plate 7 is positioned so that the positioning projection 8 provided on the connecting plate 7 is engaged with the positioning hole 9 of the rail 3. The connection plate 5 and the connection plate 7 are connected to each other by screwing the fastener 10 inserted through the hole 7b into the screw hole 5a of the connection plate 5, and the connection plate 5 is inserted into the connection groove 6. By being fitted, the protruding piece of each rail 3 is sandwiched between the connection plate 5 and the connection plate 7, and the rails 3 are mutually connected. Here, the connecting plate 7 is positioned by engaging with the positioning projections 8 and the positioning holes 9 provided in the rails 3, so that the dimension of covering each rail 3 can be accurately determined. , The connection plate 7 is accurately positioned, and each rail 3
Can be connected by the connection plate 7.

[Effects of the Invention] As described above, in the present invention, a support arm is suspended downward from a joist arranged under the floor, a rail is erected between adjacent support arms, and the rail can be freely moved under the floor. Because it is designed to be hung, the underfloor storage can be installed freely using existing joists arranged under the floor without newly constructing a large pulling, and the construction becomes large By using existing joists, rails can be installed under the floor, and the underfloor storage can be constructed freely.

Further , the rail is divided into a plurality of pieces along the longitudinal direction, a connection plate is provided between adjacent rails arranged so that the ends thereof abut each other, and the ends of the connection plates are respectively connected to the adjacent rails. The connecting plate is inserted into the connecting groove provided at the opposite end of the connecting plate, the connecting plate is disposed at the butting portion of the opposing rail, and the positioning protrusions provided at both ends of the connecting plate are provided at the end of the adjacent rail. The connection plate and the connection plate are connected and fixed by a fixing tool, respectively, so that the rail is divided into a plurality of parts so that the rail can be easily carried under the floor. In addition, since each rail is connected to each other by two members of the connection plate and the connection plate, it can be mechanically connected with high strength to form a long rail. That.

In addition, a load receiving piece is provided directly below a traveling groove in which a runner that moves the underfloor storage along the rail travels, and a mounting piece is provided at a lower end of the load receiving piece so as to be orthogonal to the support piece. Since the mounting piece is mounted on the supporting piece protruded from the lower end of the supporting arm so as to be orthogonal to the supporting arm, the load of the underfloor storage is arranged directly below the traveling groove and The load receiving piece can be reliably received by the supporting piece of the supporting arm on which it is mounted, and even if it supports the underfloor storage in a cantilevered shape, the underfloor storage does not deform without causing rail deformation. It can support a load.
