Abstract

(57) [Abstract] [Purpose] If the magnet is a little far from the adherend, the force of the magnet suddenly weakens, and if the center of the sucker floats a little above the adherend, the force of the magnet becomes stronger. Therefore, by compensating each other's drawbacks with each other's advantages, it is possible to provide a base for an on-vehicle antenna, for example, which has stable force of attachment. [Configuration] A magnet is attached to the suction surface of the suction cup in order to integrate the suction cup and the magnet.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a suction cup with a magnet having a magnet attached to the suction surface of the suction cup.

[0002]

[Prior art]

 Conventionally, there have been only suction cups or magnets, but none have integrated magnets and suction cups.

[0003]

[Problems to be solved by the device]

 If the magnet is separated from the adherend even a little, the adhesion force of the magnet suddenly weakens. Therefore, for example, in the case of an on-vehicle antenna whose base is magnetically attached to the car trunk by a magnet, the vibration of the antenna exerts a large force on the base due to the lever principle, and a part of the magnet is partially impacted by a shocking external force. It had the drawback that it could easily fall off if it floated. The present invention seeks to make up for such a defect with a suction cup.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a magnet is attached to the suction surface of the suction cup such that the magnetized surface is the same as or slightly intrudes into the surface of the suction cup around the magnet.

[0005]

[Work]

 The magnet has the maximum force when it is in close contact with the adherend, but if it is even slightly separated from the adherend, the force suddenly weakens. On the other hand, when the suction cup is pulled away from the adherend, the central portion of the suction cup initially rises with a relatively small force, but the required force increases as the central portion of the suction cup rises. Therefore, when the suction cup with magnet of the present invention is attracted and magnetically attached to a magnetic material having a flat and smooth surface, it is mainly magnetically attached to the adherend, and the magnet is attached to the adherend. If it is separated from the body even slightly, it will be sucked mainly by the suction force of the suction cup. If the external force weakens, the suction cup will return to its original state, and the magnet will again contact the adherend. When a sucker with a magnet in which the peripheral portion of the suction cup is made of a flexible magnet or a magnet is embedded in the peripheral portion and arranged, the function of increasing the airtightness between the suction cup and the adherend of the magnetic material.

【Example】

 An embodiment will be described with reference to the drawings. In FIG. 1, a magnet 2 is attached to a central portion of the suction surface of a suction cup 1 in a secret manner so that the magnetized surface thereof is slightly inserted from the surface of the surrounding suction cups. In the embodiment shown in FIG. 2, the iron box 12 to which the magnet 13 is fixed is attached to the central portion of the suction surface of the suction cup 11, and the magnet 13 and the iron box 12 are slightly inserted from the surrounding suction cup surface. Is attached to. The embodiment shown in FIG. 3 is a view of the suction cup with magnets as seen from the suction surface, and the suction cup peripheral portion of the suction cup with magnets of FIG. 1 or 2 is made of the flexible magnet 14. The embodiment of FIG. 4 is a view of the suction cup with a magnet as seen from the suction surface, and the magnet 15 is attached to the periphery of the suction cup 16 in the same manner as the suction cup surface or slightly.

[Effect of device]

 The magnet has the maximum force when it is in close contact with the adherend, but if it is even slightly separated from the adherend, the force suddenly weakens. On the other hand, when the suction cup is pulled away from the adherend, the central part of the suction cup initially rises with a comparatively small force, but as the central part of the suction cup rises, the difference in atmospheric pressure between the inside and outside and the suction cup The required force increases as the area of the raised part of the suction cup that receives the pressure of the outside air to return to the state increases. When the suction cup with a magnet of the present invention is magnetically attracted to and adsorbed on a magnetic material having a flat and smooth surface, it is magnetically attracted mainly by the magnetic attraction force when it adheres to the adherend, and the magnet is slightly separated from the adherend. However, if they are separated, they will mainly be sucked by the suction force of the suction cup. Therefore, since the respective advantages of the magnet and the suction cup are compensated for by other advantages, the magnet with suction cup strongly adheres to the adherend when the magnet is in close contact with the adherend and when it floats. Will be there. The floating suction cup returns to its original state when the external force weakens, and the magnet reattaches to the adherend. This is the same as pushing the central part of the suction cup to exhaust it, and if there is excess air in the suction cup, it also has the effect of exhausting it. In order to increase the airtightness between the suction cup and the adherend of the magnetic body, if the peripheral part of the suction cup is made of a flexible magnet or a magnet is embedded in the peripheral part of the suction cup, the adherend becomes a magnetic body. In this case, it is possible to prevent the lifting of the suction cup periphery. Also, since this sucker with a magnet has the function of an original magnet and a sucker, it is one of the inventions that the magnetic sucker is attached to the door of a refrigerator made of a magnetic material or the wall surface of a tile made of a non-magnetic material. Can be made.
