Adhesive device using magnetism

Abstract

Disclosed is a suction device having a magnet, which has a magnet contained in a suction device body made from rubber, so that it can be attached even to wood, cement wall surface, and so forth, to which a conventional suction device cannot be attached, thereby remarkably increasing the range of objects to which the suction device can be attached. The suction device includes a conical suction device body made from soft rubber and a magnet inserted in an apex portion of the suction device body. The magnet has a magnetic force of a predetermined gauss.

1 . A suction device having a magnet, comprising: 
 a suction device body  100  having a conical shape and being made from soft rubber, thereby providing a suction force after the suction device body is elastically compressed against an object; and    a magnet  130  inserted into an apex portion  110  of the suction device body  100  and having a magnetic force of a predetermined gauss.    
     
     
         2 . A suction device having a magnet, comprising: 
 first and second suction device bodies  100 A and  100 B made from soft rubber, the first suction device body  100 A including a first apex portion  110 A and a first base portion  120 A, the second suction device body  100 B including a second apex portion  110 B and a second base portion  120 B, the first and second apex portions  110 A and  110 B being integrally connected with each other through a connecting portion  101 , each of the first and second suction device bodies  100 A and  100 B having a conical shape, the first and second base portions  120 A and  120 B being oriented in opposite directions to each other, each of the first and second suction device bodies providing a suction force after they are elastically compressed against an object; and    first and second magnets  130 A and  130 B inserted in the first and second apex portions  110 A and  110 B of the first and second suction device bodies  100 A and  100 B, respectively, each of the first and second magnets  130 A and  130 B having a magnetic force of a predetermined gauss.    
     
     
         3 . A suction device having a magnet as claimed in  claim 1  or  2 , wherein the magnet  130  has two poles of N and S divided in one body.  
     
     
         4 . A suction device having a magnet as claimed in  claim 1  or  2 , further comprising a release hook, one end of which is connected with the apex portion  110  of the suction device body  100 , and the other end of which is connected with the base portion  120  of the suction device body  100 , thereby enabling a user to easily release a suctioned state of the suction device body  100 .  
     
     
         5 . A suction device having a magnet as claimed in  claim 1  or  2 , further comprising a magnetic member  140  disposed inside of the suction device body  100 , the magnetic member  140  having a shape of a net, sizes of meshes of which increase in radial directions from the apex portion  110 , the magnetic member being electrically connected with the magnet  130 .  
     
     
         6 . A suction device having a magnet as claimed in  claim 5 , wherein the magnetic member  140  is made from conductive paint.
