Summary of the Invention

Problems to be Solved by the Invention

[0004] In the anti-vibration hanger disclosed in Patent Document 1 above, an anti-vibration effect is obtained by interposing a rubber elastic body between the hanger frame and the suspension bolt. However, since this rubber elastic body is constantly in contact with each of the hanger frame and the suspension bolt, it is difficult to say that a sufficient anti-vibration effect is obtained.

[0005] The present invention has been made in view of the above problems, and an object thereof is to provide an anti-vibration hanger capable of enhancing the anti-vibration effect.

Means for Solving the Problems

[0006] To solve the above problems, the anti-vibration hanger of the present invention includes a hanger main body portion, a suspension bolt disposed in a state of being inserted through a through hole formed in the lower end of the hanger main body portion, a dropout prevention member for preventing the suspension bolt from dropping out of the hanger main body portion, a pair of permanent magnets disposed in a state where the suspension bolt is inserted therethrough, and The pair of permanent magnets are arranged between the lower end of the hanger body and the fall prevention member with the same magnetic poles facing each other. It is characterized by the following: [Effects of the Invention]

[0007] According to the present invention, the vibration damping effect can be enhanced. [Brief explanation of the drawing]

[0008] [Figure 1] This is an external view showing an embodiment of the vibration-damping hanger of the present invention. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[0010] Figure 1 is an external view showing an embodiment of the vibration-damping hanger 100 of the present invention. As shown in Figure 1, the vibration-damping hanger 100 comprises a hanger body 1, an upper suspension bolt 2, a first nut 3, a lower suspension bolt 4, a second nut 5, a pair of permanent magnets 6A and 6B, a vibration-damping member 7, a first buffer member 8, a bolt protection member 9, and a second buffer member 10.

[0011] The hanger body 1 is a hanger frame formed from C-shaped steel. As shown in Figure 1, the hanger body 1 has a C-shape when viewed from the front, and a through hole 1A1 is drilled in its upper end 1A. This through hole 1A1 is for inserting the upper suspension bolt 2. The hanger body 1 also has a through hole 1B1 drilled in its lower end 1B. This through hole 1B1 is for inserting the lower suspension bolt 4.

[0012] As shown in Figure 1, the upper suspension bolt 2 is a suspension bolt used to suspend the hanger body 1 from the building ceiling. The upper suspension bolt 2, lowered from the building ceiling, is inserted through the through hole 1A1 from the upper side of the upper end 1A of the hanger body 1, and then fastened with the first nut 3 from the lower side of the upper end 1A, thereby fixing and suspending the hanger body 1.

[0013] The first nut 3 is a nut for fixing the hanger body 1 to the upper suspension bolt 2. In other words, the first nut 3 is a nut (anti-detachment member) for preventing the hanger body 1 from falling off the upper suspension bolt 2.

[0014] As shown in Figure 1, the lower suspension bolt 4 is a suspension bolt used to suspend the ceiling material. The lower suspension bolt 4 is fixed to the hanger body 1 by inserting one end (the end opposite to the end that suspends the ceiling material) through the through hole 1B1 from the lower end 1B of the hanger body 1, and then fastening it with the second nut 5 from the upper side of the lower end 1B.

[0015] The second nut 5 is a nut for fixing the lower suspension bolt 4 to the hanger body 1. In other words, the second nut 5 is a nut (anti-fall member) for preventing the lower suspension bolt 4 from falling off the hanger body 1.

[0016] The pair of permanent magnets 6A and 6B are both formed in annular shape and are arranged with the aforementioned lower suspension bolt 4 inserted through them. Here, the inner diameter of the through hole (not shown) through which the lower suspension bolt 4 is inserted in each of the pair of permanent magnets 6A and 6B is larger than the outer diameter of the lower suspension bolt 4, which is covered with a bolt protection member 9 (described later). The pair of permanent magnets 6A and 6B are arranged between the lower end 1B of the hanger body 1 and the second nut 5 with the same magnetic pole (e.g., N pole) facing each other, and the permanent magnet 6A, which is positioned above the permanent magnet 6B, is positioned in a floating state. The pair of permanent magnets 6A and 6B are, for example, neodymium magnets. In addition, the outer surface of the pair of permanent magnets 6A and 6B may be covered with a protective member (e.g., rubber or nickel plating) to obtain impact resistance and corrosion resistance. In this case, if each of the pair of permanent magnets 6A and 6B is covered with rubber, which is a protective member, the vibration-damping hanger 100 does not need to include the first buffer member 8, which will be described later.

[0017] The vibration prevention member 7 is a member for preventing vibration of permanent magnets 6A and 6B that occurs when the distance between them decreases and the repulsive force increases. The vibration prevention member 7 is installed between permanent magnets 6A and 6B with the aforementioned lower suspension bolt 4 inserted through it. The vibration prevention member 7 is made of, for example, a hard urethane sponge.

[0018] The first buffer member 8 is a buffer member for mitigating the impact caused by the collision between permanent magnet 6A and permanent magnet 6B. The first buffer member 8 is installed between permanent magnet 6A and permanent magnet 6B together with the vibration prevention member 7, with the aforementioned lower suspension bolt 4 inserted through it. The first buffer member 8 is made of, for example, urethane rubber.

[0019] The bolt protection member 9 is a protective member for preventing wear caused by friction between the lower suspension bolt 4 and the pair of permanent magnets 6A and 6B. The bolt protection member 9 is provided so as to cover the outer surface of the lower suspension bolt 4 by lining. The bolt protection member 9 is made of, for example, urethane rubber.

[0020] The second buffer member 10 is a buffer member for alleviating the impact caused by the collision between the lower suspension bolt 4 inserted into the through-hole 1B1 and the hanger main body 1. The second buffer member 10 is at least a cylindrical heat insulating material collar that covers the edge of the through-hole 1B1 and can insert the lower suspension bolt 4 lined with the bolt protection member 9. Here, the inner diameter of the through-hole (not shown) through which the lower suspension bolt 4 of the second buffer member 10 is inserted is larger than the outer diameter of the lower suspension bolt 4 covered by the bolt protection member 9.

[0021] [[ID=�]] As described above, the vibration isolation hanger 100 includes a hanger main body 1, a lower suspension bolt 4 disposed in a state of being inserted into a through-hole 1B1 formed in the lower end 1B of the hanger main body 1, a second nut (anti-drop member) 5 for preventing the lower suspension bolt 4 from dropping off from the hanger main body 1, and a pair of permanent magnets 6A, 6B disposed in a state where the lower suspension bolt 4 is inserted. The pair of permanent magnets 6A, 6B are disposed in a state where the same magnetic poles face each other between the lower end 1B of the hanger main body 1 and the second nut 5. Therefore, according to the vibration isolation hanger 100, due to the repulsion between the pair of permanent magnets 6A, 6B, the lower suspension bolt 4 that suspends the ceiling material is in a floating state, so that the vibration propagated from the building ceiling to the hanger main body 1 via the upper suspension bolt 2 can be prevented from being propagated to the lower suspension bolt 4. Thereby, the vibration isolation effect by the vibration isolation hanger 100 can be enhanced.

[0022] Further, the vibration isolation hanger 100 includes a first buffer member 8 for alleviating the impact caused by the collision between the permanent magnets 6A, 6B. Therefore, according to the vibration isolation hanger 100, by providing the first buffer member 8, it is possible to prevent damage caused by the collision between the permanent magnets 6A, 6B.

[0023] Further, the vibration isolation hanger 100 includes a sway prevention member 7 for preventing the sway of the permanent magnets 6A, 6B that occurs when the distance between the permanent magnets 6A, 6B is reduced. Therefore, according to the vibration isolation hanger 100, it is possible to prevent the vibration isolation effect from being reduced due to the sway of the permanent magnets 6A, 6B.

[0024] Furthermore, the lower suspension bolt 4 is equipped with a bolt protection member 9 to prevent wear due to friction with a pair of permanent magnets 6A and 6B. Therefore, with the vibration-damping hanger 100, the lower suspension bolt 4 is equipped with a bolt protection member 9, which prevents wear due to friction between the lower suspension bolt 4 and the pair of permanent magnets 6A and 6B.

[0025] Furthermore, the vibration-damping hanger 100 is equipped with a second buffer member 10 that mitigates the impact caused by the collision between the lower suspension bolt 4, which is inserted through the through hole 1B1, and the hanger body 1. Therefore, with the vibration-damping hanger 100, damage caused by the collision between the lower suspension bolt 4 and the hanger body 1 can be prevented by the inclusion of the second buffer member 10.

[0026] Although the present invention has been described in detail based on embodiments above, the present invention is not limited to the above embodiments and can be modified without departing from the spirit of the invention. [Explanation of Symbols]
