Abstract

Provided is a non-adhesive type vibration reduction apparatus comprising: a support; a body; and an elastomer, wherein the elastomer is coupled in a non-adhesive manner in which an adhesive is not used, thereby preventing a separation of and reducing a damage of an elastomer which result from a weakening of an adhesive force.

First claim

The invention claimed is:

1. A non-adhesive type vibration reduction apparatus ( 100 ) disposed between a vibration source ( 600 ) and a structure ( 700 ) spaced apart from each other in a z direction based on a 3-dimensional xyz coordinate system, and using an elastomer to reduce a vibration of the vibration source ( 600 ) comprising:
a support ( 200 ) formed on an xy plane and coupled to a side of the vibration source ( 600 ) which is toward the structure ( 700 );
a body ( 300 ) including an upper side wall ( 310 ), a lower side wall ( 320 ) spaced apart from the upper side wall ( 310 ) by a predetermined distance, and a connection portion ( 330 ) connecting between the upper side wall ( 310 ) and the lower side wall ( 320 ), and coupled to a side of the structure ( 700 ) which is toward the vibration source ( 600 );
the elastomer ( 400 ) including a base ( 410 ) being coupled to the body ( 300 ), a first elastic portion ( 420 ) protruding and extending from the base ( 410 ) in the z direction, and a protruding portion ( 430 ) protruding from the first elastic portion ( 420 ) toward the support ( 200 );
a first cover disposed where the body ( 300 ) and the elastomer ( 400 ) are coupled; and
a second cover disposed where the support ( 200 ) and the elastomer ( 400 ) are coupled,
wherein an end of the support ( 200 ) is provided with a first groove ( 210 ),
wherein the protruding portion ( 430 ) is formed to correspond to an inside shape of the first groove ( 210 ) and is inserted into the first groove ( 210 ) to be coupled thereto,
wherein the body ( 300 ) includes a second groove ( 340 ) which is formed on an inner surface of the upper side wall ( 310 ) and the lower side wall ( 320 ),
wherein the base ( 410 ) has an outside shape corresponding to an inside shape of the second groove ( 340 ) and is inserted into the second groove ( 340 ) to be coupled thereto,
wherein the connection portion ( 330 ) comprises a side wall ( 330 ) enclosing the upper side wall ( 310 ) and the lower side wall ( 320 ) and a third groove ( 350 ) formed on an inner surface of the side wall ( 330 ),
wherein the elastomer ( 400 ) further includes a side wall base ( 440 ) having an outside shape corresponding to an inside shape of the third groove ( 350 ) and the side wall base ( 440 ) is inserted into the third groove ( 350 ) to be coupled thereto.

2. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 1 , wherein the elastomer ( 400 ) further includes a second elastic portion ( 450 ) protruding and extending from the side wall base ( 440 ) to the first elastic portion ( 420 ).

3. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 1 , wherein the connection portion ( 330 ) comprises a plurality of pillars ( 330 ).

4. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 1 , wherein corners of the respective coupled parts of the support ( 200 ), the body ( 300 ), the elastomer ( 400 ), and the cover ( 500 ) have a curvature.

5. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 1 , wherein the support ( 200 ) is provided with a separation portion ( 220 ) which is separated from and coupled to the support ( 200 ).

6. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 5 , wherein
a module ( 150 ) consisting of the body and the elastomer is separated by the separation portion ( 220 ), and is coupled to the support ( 200 ) in several directions by rotating the module ( 150 ).

7. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 1 , wherein a vertical distance from an end of the second cover to an inner wall of the elastomer ( 400 ) is less than a vertical distance from the support ( 200 ) to an inner wall of the elastomer ( 400 ).

8. A non-adhesive type vibration reduction apparatus ( 100 ) disposed between a vibration source ( 600 ) and a structure ( 700 ) spaced apart from each other in a z direction based on a 3-dimensional xyz coordinate system, and using an elastomer to reduce a vibration of the vibration source ( 600 ), comprising:
a support ( 200 ) formed on an xy plane and coupled to a side of the vibration source ( 600 ) which is toward the structure ( 700 );
a body ( 300 ) including an upper side wall ( 310 ), a lower side wall ( 320 ) spaced apart from the upper side wall ( 310 ) by a predetermined distance, and a connection portion ( 330 ) connecting between the upper side wall ( 310 ) and the lower side wall ( 320 );
the elastomer ( 400 ) including a base ( 410 ) being coupled to the body ( 300 ), a first elastic portion ( 420 ) protruding and extending from the base ( 410 ) in the z direction, and a protruding portion ( 430 ) protruding from the first elastic portion ( 420 ) toward the support ( 200 ); wherein an end of the support ( 200 ) is provided with a first groove ( 210 ), wherein the protruding portion ( 430 ) is formed to correspond to an inside shape of the first groove ( 210 ) and is inserted into the first groove ( 210 ) to be coupled thereto.

9. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 8 , further comprising
a first cover extending across a coupling between the body ( 300 ) and the elastomer ( 400 ).

10. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 8 , wherein
the first cover contacts both the body ( 300 ) and the elastomer ( 400 ).

11. The non-adhesive type vibration reduction apparatus ( 100 ) of claim 8 , wherein
the body is arranged to be coupled to a side of the structure ( 700 ) which is toward the vibration source ( 600 ).
