Description

    TECHNICAL FIELD
  • 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.

[0004]
  • It is an object of the present invention to provide a suction device having a magnet, which increases the range of objects to which the suction device can be attached, even to include wood, cement wall surfaces, and so forth, and which is prevented from easily sliding down or being easily separated from the surface of an object by impact, deformation, change of moisture or temperature, or the like.

  • FIG. 5 is a view showing a construction of a magnet employed in a suction device according to the present invention.[0016]
    • BEST MODE FOR CARRYING OUT THE INVENTION
  • Reference will now be made in detail to the preferred embodiments of the present invention. [0017]
  • FIG. 1 is a perspective view of a suction device according to a preferred embodiment of the present invention, FIG. 2 is a sectional view of the suction device, taken along line A-A′ in FIG. 1, FIG. 3 is a sectional view illustrating used state of the suction device shown in FIG. 1, and FIG. 5 is a view showing a construction of a magnet employed in a suction device according to the present invention. [0018]
  • As shown in FIGS. 1 and 2, the suction device according to a preferred embodiment of the present invention has a conical [0019] 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. When the suction device body 100 is located in contact with a surface of an object and force is applied 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 [0020] 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.
  • Further, a [0021] 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.
  • The suction device according to the present embodiment further includes a [0022] release hook 150 for enabling a user to easily release a suctioned state of the suction device body 100. The release hook 150 is wound like a hook to form a hollow space inside thereof. One end of the release hook 150 is connected with the apex portion 110 of the suction device body 100, while the other end of the release hook 150 is connected with the base portion 120 of the suction device body 100. 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. [0023]
  • The suction device shown in FIG. 4 includes first and second suction device bodies [0024] 100A and 100B, and first and second magnets 130A and 130B each having a magnetic force of a predetermined gauss. The first suction device body 100A includes a first apex portion 110A and a first base portion 120A, and the second suction device body 100B includes a second apex portion 110B and a second base portion 120B. The first apex portion 110A and the second apex portion 110B are integrally connected with each other through a connecting portion 101. 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 101A 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 110B of the first suction device body 101A 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 [0025] 100A and the second suction device body 100B can provide a separate suction force.
  • In order to attach the suction device according to the present invention, which has the construction described above, to a rough surface such as a surface of wood or cement wall, a [0026] 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.
  • Further, 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 [0027] first apex portion 110A and the second apex portion 110B 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.
  • When the [0028] release hook 150 connected to an outer surface of the apex portion 110 is pulled upward, the base portion 120 of the conical suction device body 100 can be easily detached from a surface of an object. Therefore, the release hook 150 can be effectively used in releasing the attached state of the suction device from the suctioned surface of the object.
  • Industrial Applicability [0029]
  • As can be seen from the foregoing, a suction device according to the present invention 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 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 for an object to which the suction device is attached. Moreover, the suction device according to the present invention increases the range of objects to which the suction device can be attached, for example, the suction device can be attached even to wood, cement wall surface, etc. In addition, the suction device according to the present invention is prevented from easily sliding down or being easily separated from the surface of the object by impact, deformation, change of moisture or temperature, or the like. [0030]
  • While this invention has been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments and the drawings, but, on the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims.
