Summary of the Invention

Problems to be Solved by the Invention

[0005] In the operation of using bolts screwed on the side surface of the instruments, it is necessary to completely remove the bolts on the side surface. Therefore, when the bolts are completely removed, the installation of the instruments may become unstable. Moreover, the work of screwing the removed bolts back to their original positions also requires time and effort.

[0006] In addition, for the mounting bracket described in Patent Document 1, in order to fix the end of the rope, it is necessary to previously fix the receiving bracket by welding or the like. Therefore, it takes a lot of labor in the mounting process of the mounting bracket, and fixing means such as welding cannot be used for inappropriate instruments.

[0007] Therefore, the present invention was created to solve the above problems, and an object thereof is to provide a mounting bracket that does not require fixing means such as welding and can connect a wire rope simply by loosening a bolt that is pre-screwed to instruments.

Means for Solving the Problems

[0008] The first means in the present invention to achieve the above object is a mounting bracket for attaching a vibration-damping member to instruments P. A main body 1 fixed to the instruments P with a bolt P1 is provided with an insertion hole 3 sized to allow the head of the bolt P1 to pass through, and at least one locking hole 4 formed by extending from the insertion hole 3. The locking hole 4 has a width that allows the shaft portion of the bolt P1 to be inserted and locked to the head of the bolt P1, and is configured to be fixed to the instruments P by tightening the bolt with the locking hole 4.

[0009] The second means is that a mounting portion for attaching a vibration-damping member is formed on the main body 1.

[0010] The third means is that the main body 1 is plate-shaped, and the main body is bent between the insertion hole 3 and the locking hole 4.

[0011] In the fourth means, the locking holes 4 are arranged at equal angles around the insertion hole 3.

[0012] The fifth means The main body 1 is a polygonal plate-like member. The insertion hole 3 is formed through the center of the main body 1. Extension parts 3A extend radially from the insertion hole 3 toward each corner of the main body 1. The locking holes 4 are continuously formed on the tip sides of the respective extension parts 3A. Each corner of the main body 1 is bent in the same direction with a bending part 1B that crosses each extension part 3A as a boundary.

[0013] The sixth means is that the bolt P1 inserted and locked in the insertion hole 3 and the wire rope Q connected to the locking hole 4 are arranged substantially diagonally. 。

[0014] The seventh means is, in the mounting bracket, to loosen the bolt P1 provided in advance on the appliances, insert the bolt P1 into the insertion hole 3 of the main body 1, slide the position of the main body 1 upward and move it so that the bolt P1 is locked from the insertion hole 3 to the locking hole 4, tighten the bolt P1 locked in the lowermost locking hole 4 to fix the main body 1 to the appliances, and connect the wire rope Q to the locking holes 4 at two places in the upper part of the fixed main body 1 to prevent swaying. 。

[0015] The eighth means is that the main body 1 is a plate-like member in the shape of a substantially equilateral triangle. 。

Advantages of the Invention

[0016] According to the present invention, it becomes possible to connect the wire rope simply by loosening the bolts that are pre-fastened to the instruments.

Modes for Carrying Out the Invention

[0018] The mounting bracket of the present invention is used, for example, when attaching a wire rope Q for anti-sway to instruments P installed in a station building. In particular, it connects the wire rope Q or the like via the main body 1 attached to the bolt P1 that is pre-fastened to the instruments P.

[0019] The illustrated main body 1 is a substantially equilateral triangular plate-like member, and an insertion hole 3 through which the bolt P1 passes is formed at the center of the main body 1 (see FIG. 1). Further, three extension parts 3A extend radially from the insertion hole 3 toward the respective corner parts 1A of the main body 1 at equal angles, and locking holes 4 are continuously formed on the tip sides of the respective extension parts 3A.

[0020] The insertion hole 3 is formed to have a size capable of inserting the head of the bolt P1, and the extension portion 3A is formed to have a width through which the shaft portion of the bolt P1 inserted into the insertion hole 3 can move. The locking hole 4 is formed at the end side of each extension portion 3A and is formed to have a width at which the head of the inserted bolt P1 is locked.

[0021] All of these insertion holes 3 and locking holes 4 are formed with a crimping portion 5 along the peripheral edge (see Fig. 4). This crimping portion 5 facilitates the operation of moving the main body 1 from the insertion hole 3 to the locking hole 4 along the bolt P1, and can prevent unexpected accidents by preventing damage to the wire rope or the like by the edge of the peripheral edge.

[0022] When the bolt P1 is tightened at the position of the locking hole 4, the main body 1 is fixed to the appliances P (see Fig. 5). Further, a wire rope Q or a string-like body is connected to the remaining two locking holes 4 and used for anti-sway or the like. Therefore, by using the three locking holes 4 formed in the triangular main body 1, it is possible to fix the main body 1 and connect the wire ropes Q at two locations. Note that the number of locking holes 4 can be arbitrarily changed. Also, the locking holes 4 to which the wire rope Q or the string-like body is connected do not necessarily need to be formed by extending from the insertion hole 3, and an eye bolt or the like may be provided.

[0023] Furthermore, each corner portion 1A of the main body 1 in which the locking hole 4 is formed is bent in the same direction with the bending portion 1B crossing each extension portion 3A as a boundary (see Fig. 2). As a result, for the locking holes 4 in which the bolts P1 of the main body 1 fixed to the appliances P are not fixed, a gap is formed between the appliances P and the locking holes 4 due to the bending angle of each corner portion 1A, facilitating the attachment operation of the wire rope Q or the like. Note that the illustrated corner portion 1A is bent at an angle of 20° from the main body 1 side (see Fig. 3).

[0024] Then, when the bolt P1 inserted through the locking hole 4 is tightened to fix the corner portion 1A, the central portion of the main body 1 is fixed in a state of being bent at an angle of 20° with respect to the corner portion 1A. Further, the remaining corner portions 1A to which the wire ropes Q are connected are fixed in a state of being bent at an angle of 20° respectively from the central portion of the main body 1 (see FIG. 5). As a result, a sufficient space is formed between the appliances P and the corner portion 1A for the operation of connecting the wire ropes Q, facilitating the connection operation of the wire ropes Q. Also, even if the bolt P1 becomes loose, the bent portion 1B prevents the bolt P1 from moving toward the insertion hole 3 side, preventing the main body 1 from falling off the bolt P1.

[0025] Next, based on FIG. 6, the installation procedure of the mounting bracket of the present invention will be described. First, as shown in (a), loosen the bolt P1 provided in advance on the appliances P, and insert the bolt P1 into the insertion hole 3 of the main body 1. Then, as shown in (b), slide the main body 1 upward and move it so that the bolt P1 is locked from the insertion hole 3 to the locking hole 4. Further, as shown in (c), when the bolt P1 locked in the lowermost locking hole 4 is tightened, the main body 1 is fixed to the appliances P. Finally, as shown in (d) of the same figure, connect the wire ropes Q to the two upper locking holes 4 of the fixed main body 1 to prevent sway. Also, instead of the wire ropes Q, all-thread bolts or turnbuckles may be used to prevent sway, and the main body 1 may be round, polygonal, or the like.

[0026] Note that the embodiments of the present invention are not limited to the illustrated examples, and design changes within the scope that do not change the gist of the present invention are free for changes in each component part, the type of appliances P, the installation position, etc. Also, the anti-sway members refer to, for example, wire ropes, string-like bodies, turnbuckles, all-thread bolts, etc.
