Description

[Detailed Description of the Invention] The present invention provides an expansion joint hardware that can handle displacement in multiple directions and that can handle displacement in multiple directions using the displacement handle without impairing functionality. Regarding.

As a conventional displacement handling device, there is a known displacement handling tool that involves engagement of two parts, but it can only handle displacement in one direction. Various displacement devices that can accommodate displacement in two directions or in multiple directions have been considered, but these devices have the drawbacks of complex structures and difficulty in providing sufficient functionality. The same is true for expansion joint hardware that uses displacement support.

This invention can accommodate displacement in multiple directions and has a simple structure.
It is an object of the present invention to provide a displacement support tool that can perform a light function with 1"L, and an expansion joint hardware that utilizes the displacement support. The displacement corresponding tool is characterized in that a rod material is inserted into one or more annular displacement tools whose inner edge shape increases in diameter as it approaches the outer edge from the center, and according to the present invention. The expansion joint hardware consists of 1 to 3 annular displacement tools whose inner edge shape increases in diameter as it approaches the outer edge from the center, and a spherical body with a through hole, which are rotatably housed in a container. It is characterized in that a rod material is inserted through three displacement devices consisting of one or two spherical displacement devices, and a cover plate is attached to both displacement devices in the center.

In the present invention, the annular displacement tool may be C-shaped with a notch in one part, and the spherical body may be a sphere or a spherical body having a notch in the shape of a round slice of a sphere. Good too.

The present invention will now be described in detail with reference to the accompanying drawings.

fjS1 Figures (A) and (B) show one example of a displacement support tool,
Reference numeral 1 denotes a C-shaped annular displacement tool whose inner edge becomes larger in diameter as it approaches the outer edge from the center, and has a notch 1a in one part and a groove 1b along the outer edge; 2 is an annular displacement tool. 1
The rod material 2 is inserted through the rod material 2, and the rod material 2 can not only be moved in the left-right direction, but it is also capable of being displaced in the diagonal direction without moving the annular displacement tool, as shown by the dotted line. Sho annular displacement 5! -1 is made of a resilient elastic material such as metal or polycarbonate resin, and is made small by pressing it with your fingers, and then fitted into the through hole 3a of the support plate 3 using the groove 1b as shown in Fig. 4. It can be fixed together. Although the cross-sectional shape of the inner edge of the annular displacement tool 1 is semicircular as shown in FIG. I'b is a groove provided on the outer edge. Further, as in the displacement corresponding tool 1'' shown in FIG. 3, a part of the outer edge on the left side along the groove 1''b can be removed and the press fitting +h can be fixed in the through hole 3a of the support plate 3. This is the notch 1 shown in the annular displacement JA1.

It is rotatably housed inside, and a rod material is inserted into the through hole 5a to accommodate displacement. It should be noted that the illustrated container 6 can be made by combining a plurality of divided pieces.

Although the displacement support and the displacement used therein have been described above, the rod material used may be solid, hollow, or resilient elastic rod material. Moreover, the number of displacement tools may be one or more. Next, one example of a displacement support tool using a plurality of displacement tools will be explained.

FIG. 6 shows one example of a displacement corresponding tool, in which the displacement corresponding tool 7 has a rod material 8 inserted through three annular displacement devices 1, l, 1, and the annular displacement device 1 in the center is a rod material. The annular displacement device on both sides is fixed in position by the perforated l-pieces 9.9 on both sides, which are externally fitted and fixed on 8.

In the case of such usage, the two inner springs 11 and 11 of the displacement adjustment tool 7 may be replaced with one continuous spring, and the two inner springs 11 and 11 of the displacement adjustment tool 21 can be replaced with one continuous spring. Spring 28.28 may also be replaced by one continuous spring. The spring 28 may be removed if it is unnecessary. The displacement mode of the displacement corresponding tools 7 and 21 can be understood from the displacement mode of the displacement corresponding tool 13, so a description thereof will be omitted.
