Definitions

  • the present invention relates to a suction device having a magnet, and more particularly to 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 surfaces, 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.
  • a suction device has a conical body made from rubber.
  • the suction device is attached by suction to a surface of an object such as glass, the suction device is located in contact with the surface of the object and force is then applied inward upon the suction device, that is, directly downward toward the object surface from the apex portion of the cone. Then, a base portion of the flexible conical body made from rubber is compressed toward the surface of the object, while a vacuum is formed between the suction device and the surface of the object.
  • the suction device having the construction described above provides adhesive force to a surface of glass or car window, a smooth surface of a tile, or the like, even without a separate adhesive agent, thereby enabling a small toy, a blind for a car window, or the like, to be hung on a surface of a mirror, car window, or the like.
  • the conventional suction device as described above can provide adhesive force only for a smooth surface, so that its usable range is inevitably restrictive. Further, the conventional suction device may easily slide down or may be easily separated from a surface of an object by impact, deformation, change of moisture or temperature, or the like. Moreover, the conventional suction device has a relatively small suction force capable of holding up only a light load.
  • the present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a suction device having a magnet, which has a conical suction device body having a magnet contained in an apex portion of the suction device body, so that the suction device can provide not only a vacuum suction force but also a magnetic force by the magnet contained in the apex portion, that is, the suction device can provide an increased holding force toward an object to which the suction device is attached.
  • a suction device having a magnet comprising: a suction device body 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 inserted in an apex portion of the suction device body and having a magnetic force of a predetermined gauss.
  • the suction device may further comprise a magnetic member disposed inside of the suction device body, the magnetic member having a shape of a net, sizes of meshes of which increase in radial directions from the apex portion, the magnetic member being electrically connected with the magnet.
  • a suction device having a magnet comprising: first and second suction device bodies made from soft rubber, the first suction device body including a first apex portion and a first base portion, the second suction device body including a second apex portion and a second base portion, the first and second apex portions being integrally connected with each other through a connecting portion, each of the first and second suction device bodies having a conical shape, the first and second base portions 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 inserted in the first and second apex portions of the first and second suction device bodies, respectively, each of the first and second magnets having a magnetic force of a predetermined gauss.
  • the magnet has two poles of N and S divided in one body and the magnetic member is made from electro-conductive paint.
  • the suction device may further comprise a release hook, one end of which is connected with the ' apex portion of the suction device body, and the other end of which is connected with the base portion of the suction device body, thereby enabling a user to easily release a suctioned state of the suction device body.

  • the suction device has a conical suction device body 100 made from soft rubber, which has a conical shape increasing in a radial direction from an apex portion 110 to a base portion 120.
  • the suction device body 100 is located in contact with a surface of an object and force is applie-d to the apex portion 110 directly downward from the apex portion 110, the suction device body 100 made from rubber is compressed onto the surface of the object, so as to form a vacuum between the suction device body 100 and the surface of the object, thereby providing a holding force for the surface of the object.
  • a magnet 130 having a magnetic force of a predetermined gauss is inserted in the apex portion 110 of the conical suction device body 100.
  • the magnet 130 inserted in the apex portion 110 may have two poles of N and S divided in one body, thereby maximizing a suction force of the suction device body 100 utilizing magnetism.
  • a magnetic member 140 is electrically connected with the magnet 130.
  • the magnetic member 140 is disposed inside of the suction device body 100 and has a shape of a net spreading in radial directions from the apex portion 110 to the base portion 120 of the suction device body 100, that is, the net having meshes, sizes of which increases in radial directions from the apex portion ' 110 to the base portion 120.
  • the magnetic member 140 may be formed by applying paint containing conductive material and may include a conductive member attached to the inner surface of the suction device body 100, such as a flexible iron wire.

Therefore, in a state where the suction device has been attached by suction to a surface of an object, when a user pulls the release hook 150 with a slight force, the base portion 120 is pulled up and detached from the surface of the object, so that the entire suction device can be easily detached from the suctioned surface of the object.
  • Fig. 4 is a perspective view of a suction device according to another preferred embodiment of the present invention.

  • the first base portion 120A and the second base- portion 120B are oriented in opposite directions to each other.
  • Each of the first base portion 120A and the second base portion 120B has an area increasing in a radially outward direction from the connecting portion 101, so that each of the first suction device body 100A and the second suction device body 100B has a conical shape.
  • the first magnet 130A and the second magnet 130B are disposed in the first apex portion 110A and the second apex portion HOB of the first suction device body 100A and the second suction device body 100B, respectively.
  • the suction device shown in FIG. 4 is useful in holding two bodies spaced from each other, such as two spaced steel plates, since each of the first suction device body 100A and the second suction device body 100B can provide a separate suction force.
  • a steel plate 200 which attracts a magnet is attached to the rough surface such as a surface of wood or cement wall by means of an adhesive agent. Then, the suction device according to the present invention is pressed onto the steel plate 200, so that the suction device made from rubber is compressed and thereby forms a vacuum between the suction device and the steel plate 200, thereby providing a suction force, while attraction is applied between the steel plate 200 and the magnet 130 inserted in the apex portion. As a result, the suction, device according to the. present invention can provide an increased holding force.
  • the suction device shown in FIG. 4 is useful in connecting two spaced members such as two spaced steel plates. That is, in the suction device shown in FIG. 4, the first apex portion 110A and the second apex portion HOB are integrated with each other through the connecting portion 101, and the first base portion 120A and the second base portion 120B are oriented in opposite directions to each other from the connecting portion 101 containing the first base portion 120A and the second base portion 120B, so that the suction device can simultaneously provide two holding forces in opposite directions.
