Embodiment for Carrying Out the Invention

[0021] The mounting bracket of the present invention is for attaching a wire P and a turnbuckle, which are used for anti-vibration of, for example, a light-emitting display board or a lighting fixture suspended from a building body in a station building, to a steel pipe Q (see FIGS. 6(A) and (B)).

[0022] The main configuration of the present invention includes a fixing bracket 1, a fixing bolt 6, a fixing nut 7, and a coil spring 8 (see FIG. 1).

[0023] The fixing bracket 1 is a strip-shaped member that secures the steel pipe Q by clamping its sides. It is formed by a contact portion 2 that clamps the steel pipe Q and connecting portions 3 that extend from both ends of the contact portion 2 (see Figure 2). The connecting portions 3 are then fixed to each other with fixing bolts 6, and a wire P for preventing swaying is connected to a burring 5 through which these fixing bolts 6 are inserted. The fixing bracket 1 shown in the figure uses a pair of brackets of the same shape, but these may be integrally molded.

[0024] A spring member is attached to one of the fixing bolts 6, and the elastic force of the spring member is configured to close the pair of fixing brackets 1 that sandwich the steel pipe Q (see Figures 5(a) and (b)). The illustrated spring member is a coil spring 8. The coil spring 8 is installed between the fixing nut 7, which is screwed to the fixing bolt 6, and the fixing bracket 1, and the pressing biasing force of the coil spring 8 is configured to maintain a constant rotational position between the fixing brackets 1. In the illustrated example, a nut with a washer is used for the fixing nut 7 (see Figures 2 and 3). Furthermore, the spring member does not necessarily have to be a coil spring; it only needs to have a biasing force that brings the fixing brackets 1 closer together, and for example, a leaf spring material can also be used.

[0025] The fixing bolt 6 shown in the figure is a fixing bolt with a square root, and the bolt insertion hole 4 forms a fitting recess 4A that fits the square root portion 6A of this fixing bolt 6 (see Figure 3). Then, the fixing bolt 6 is inserted through each bolt insertion hole 4 and the fixing nut 7 is screwed on to secure it (see Figure 2). Since the fixing bolt 6 inserted through the bolt insertion hole 4 is fixed in the fitting recess 4A, it does not rotate when the fixing nut 7 is screwed on. Although not described in the embodiment, if a hexagonal bolt is used, the fitting recess 4A can be changed by providing a projection on the fixing fitting 1 so that an emboss or the like makes contact with at least one side of the bolt head to the extent that the fixing bolt 6 does not rotate.

[0026] Furthermore, the bolt insertion holes 4 are provided with burrings 5 ​​that protrude in the direction of the opposing fixing brackets 1 (see Figure 2). These burrings 5 ​​are configured to come into contact with each other when the steel pipe Q is clamped between the fixing brackets 1. As a result, the contacting burrings 5 ​​ensure an appropriate gap when connecting the wire P or turnbuckle to the fixing bolt 6 (see Figure 5(d)). This also prevents the wire P from directly contacting the threaded portion of the fixing bolt 6, thus preventing damage to the wire P. The gap between the fixing brackets 1 only needs to be wide enough for the wire P to pass through without difficulty, so if the height of the burring 5 is greater than the width of the wire P, it is sufficient for the burring 5 to be present on only one of the fixing brackets 1.

[0027] The steel pipe Q used to fix the mounting bracket of the present invention can be a steel pipe with a round cross-section or a square cross-section (see Figures 6(a) and (b)). Therefore, the shape of the contact portion 2 of the fixing bracket 1 is formed to match the shape of each steel pipe Q.

[0028] Next, Figure 5 shows the procedure for using the mounting bracket of the present invention. First, as shown in Figure (a), the fixing brackets 1 are temporarily assembled using only the fixing bolts 6 equipped with coil springs 8, and one of the fixing brackets 1 is brought into contact with the side surface of the steel pipe Q.

[0029] Next, as shown in Figure (b), the other fixing bracket 1 is rotated to contact the side of the steel pipe Q. At this time, each fixing bracket 1 closes to each other due to the elastic force of the coil spring 8, so each fixing bracket 1 is temporarily fixed to the side of the steel pipe Q and will not fall even if the worker lets go. If, in the absence of one of the fixing bolts 6, the distance between the connecting parts 3 is greater than the steel pipe Q, it is also possible to insert it into the steel pipe Q from the side while it remains in the state shown in (b).

[0030] From this temporary fastening state, the remaining fixing bolts 6 are connected as shown in Figure (c), and the fixing bracket 1 is secured to the steel pipe Q by tightening the two fixing nuts 7.

[0031] Finally, as shown in Figure (d), the bracing wire P is connected to the fixing bracket 1. At this time, the spacing between the contacting burrings 5 ​​facilitates the wire P connection work. Alternatively, a cylindrical body or projection may be used to form the gap instead of the burrings 5.

[0032] Furthermore, the embodiments of the present invention are not limited to those shown in the illustrations, and design modifications such as changing each component or the type of steel pipe Q used for fixing are permitted as long as they do not alter the essence of the present invention.
