The present invention relates to a vertical impact floor impact sound generator, and more particularly, to a vertical impact floor impact sound generator that adopts a simple structure and is simple to manufacture and operate, and that can be repeatedly repeatedly dropped at a constant height. .

In the modern society, multi-family housing is a typical form of housing that shares the walls and floors of neighbors, and the noise generated through the floor from the upper generation, children's leaping, footsteps, and knocking of objects can be transferred to the neighboring generation through the structure. The noise generated by radiation is called floor impact sound.

The floor impact sound is evaluated by dividing it into light impact sound and heavy impact sound according to the characteristics of the noise.

First, the light impact sound is an evaluation index indicating the level of noise in the floor directly due to the dropping of a small object or the impact applied to the floor when the furniture is moved, which is measured using a standard tapping machine.

In addition, the weight shock sound is an evaluation index indicating the degree of noise in the floor directly below the heavy impact generated when the child runs or runs, which is measured using a standard bang machine.

As a device for measuring the weight impact sound, a heavy sound generator having several blow parts reciprocating by a cylinder under the body and a heavy sound generator hitting at a predetermined interval by a tire or a heavy body have been developed and used. It is true.

As shown in FIGS. 1A and 1B to solve the conventional problems, a floor impact sound generator has been proposed as Korean Application No. 20-2004-28166.

The conventional floor impact sound generator includes a pedestal (1) formed with a partition wall (1b) having a control unit (1a) on the side of the body, the storage space is formed inside the drive motor (1c); A support shaft 2 installed on the pedestal 1b and provided with a pulley 2a at a center portion of the body and receiving and rotating the power of the drive motor 1c fixed to one side of the pedestal 1; The striking member 4 configured to be fixed with the tire 4b at the end of the support 4a having a predetermined length above the main body 3, which is supported by the drive shaft 2, and the other end thereof is fixed to the main body 3. Wow; A sub-axis 5 fixed in the main body 3, the friction link 5a in contact with the pulley 2a, the release ring 5b, and a spring (not shown) combined; A fixed support (6) fixed to the inside of the partition (1b), having a drive shaft (2) located therein, and having a sub chain (6a) fixedly installed at one end thereof; The guide shaft 7b, to which the weight body 7a fixed to the other end of the sub chain 6a is coupled, is axially connected to the main body 3, and the release ring 5b is rotated by the rotation of the guide shaft 7b. The guide roller (not shown) for rotating the shaft is composed of a release means 7 fixed to the guide shaft 7b by the link member 7c.

In the conventional floor impact sound generator, when the power generated from the drive motor 1c rotates the drive shaft 2 through the drive chain 1d, the sub-axis (by the friction link 5a contacting the pulley 2a) 5) is fixed, and the sub-axis 5 and the fixed body main body 3 is rotated together to lift up.

At this time, the release ring 5b fixed to the sub-axis 5 also rotates together with the main body 3, and simultaneously pushes the guide roller located at the bottom of the release ring 5b backward, thereby releasing the guide roller. The means 7 are also rotated simultaneously with the main body 3.

In addition, the return spring is connected to one end of the guide roller and one end of the release ring 5b so that the mutual operation can be performed more smoothly.

In the process of retracting the guide roller by the rotation of the main body 3, when the friction link 5a in contact with the pulley 2a reaches a top dead center, the pulley 2a cannot push the release ring 5b any further. It will not retract the guide roller.

In addition, the weight body 7a integrally formed with the guide roller rotates together when the main body 3 rotates. When the body body 3 rotates a certain distance, the weight body 7a is formed by the sub chain 6a bound to the fixed support 4a. Rotates backward by weight.

That is, if the sub chain 6a connected to the fixed support 4a and the weight body 7a does not have a margin in the length when the weight body 7a is positioned in the vertical direction by using the length, 6a grabs the weight 7a and naturally rotates only the weight 7a to the rear side.

Then, while the striking member 4 strikes the bottom surface, the friction link 5a comes into contact with the pulley 2a again, thereby transmitting power of the drive shaft 2 to the sub shaft 5 again.

That is, after the striking member 4 hits the bottom surface, the friction link of the subshaft 5 is driven again.

In contact with the pulley 21 of the shaft 20 is to raise the main body 30 while the sub-axis 50 is fixed.

In this way, by the rotation of the drive shaft (2) and the binding and release of the sub-shaft (5), the striking member (4) of the main body 30 to perform a repetitive operation, the sub-axis (5) is a weight ( As 7a) is moved, the sub-axis 5 is bound and released.
