Description

  The present invention relates to a magnet holder for removably holding a sheet-like material such as paper on a wall surface.

  Conventionally, as this kind of magnet holder, it is spread over 180 degrees on the back side facing the wall surface, in other words, when one is parallel to the wall surface, the other is inclined with respect to the wall surface. And a holder body having a central protrusion formed between the first surface and the second surface, and a magnet on each of the first surface and the second surface. Is known (see, for example, Patent Document 1).

  Thus, the magnet holder is used by being attached to a wall on which the magnet can be attracted, and the first surface is obtained by operating the holder body as a seesaw so that the central projecting portion serves as a fulcrum. The magnet disposed on the second surface and the magnet disposed on the second surface can be selectively attracted to the wall surface. Therefore, by carrying out seesaw operation on the holder body, a sheet or other sheet-like material is detachably sandwiched between the magnet of the first surface and the wall surface, or between the magnet of the second surface and the wall surface. Can be made.

  However, in such a configuration, the center protrusion protrudes every time switching between the state in which the first surface magnet is attracted to the wall surface and the state in which the second surface magnet is attracted to the wall surface. Only the portion is in contact with the wall surface, and a state in which any magnet is separated from the wall surface occurs instantaneously. Therefore, when such switching operation is repeated, there is a problem that the entire magnet holder is likely to be displaced with respect to the wall surface.

It is comprised so that adsorption | suction can be cancelled | released.

  Hereinafter, an example of the usage pattern of the magnet holder 1 will be described with reference to FIGS. 11 and 12.

  In this usage mode, the magnet holder 1 is attached to a wall surface W such as a whiteboard in a substantially horizontal posture so that a sheet-like object S such as a document is detachably held on the wall surface W. . In FIG. 11, the main magnet 4 provided on the first surface 3 a of the movable member 3 and the secondary magnet 5 provided on the back surface 2 a of the stationary member 2, that is, the third surface, are attracted to the wall surface W by magnetic force. Indicates the state. From this state, the sheet-like object S is inserted between the main magnet 4 provided on the second surface 3b of the movable member 3 and the wall surface W, and the end portion on the second surface 3b side of the movable member 3 is moved to the wall surface. When pressed toward W, the movable member 3 rotates about the axis of the hinge 6 so that the main magnet 4 on the first surface 3a side is separated from the wall surface W and the main magnet 4 on the second surface 3b side is the wall surface. As shown in FIG. 12, the main magnet 4 on the second surface 3b side is finally attracted to the wall surface W via the sheet S. That is, the sheet-like material S is sandwiched between the main magnet 4 and the wall surface W and is held on the wall surface W. From this state, when the end of the movable member 3 on the first surface 3a side is pressed toward the wall surface W, the movable member 3 rotates around the axis of the hinge 6 and becomes the main surface on the second surface 3b side. As the magnet 4 moves away from the wall surface W, the main magnet 4 on the first surface 3a side approaches the wall surface W, and finally, the main magnet 4 on the first surface 3a side is attracted to the wall surface W as shown in FIG. Is done. That is, the state where the sheet-like object S is sandwiched between the main magnet 4 and the wall surface W is released, and the sheet-like object S can be removed from the wall surface W.

  As described above, the movable member 3 can be operated as a seesaw to switch the holding state of the sheet-like material S. However, even when the movable member 3 is operated, the subordinate magnet 5 provided on the stationary member 2 is always in contact. The state of being attracted to the wall surface W is maintained. Therefore, even if the movable member 3 is repeatedly operated as a seesaw, the entire magnet holder 1 can be prevented or suppressed from being displaced with respect to the wall surface W.

  In addition, since the stationary member 2 and the movable member 3 are connected to each other via a hinge 6 so as to be relatively rotatable, the stationary member 2 and the movable member 3 can be handled integrally and are stable. The desired performance can be continuously exhibited by inducing relative motion. In particular, according to the configuration as in the above embodiment, all the components of the hinge 6 can be integrally provided on the stationary member 2 and the movable member 3, so that the number of components can be minimized.

  In addition, the movable member 3 includes a first surface 3a and a second surface 3b, and the stationary member 2 is disposed between the first surface 3a and the second surface 3b. The member 3 is supported so that the first surface 3a and the second surface 3b can selectively approach the wall surface W, and the main magnet 4 is respectively attached to the first surface 3a and the second surface 3b. Since the sheet-like material S is held between the main magnet 4 on the second surface 3b side and the wall surface W, the sheet-like material S is stably held on the wall surface W. In addition, the main magnet 4 on the second surface 3b side is held away from the wall surface W when the main magnet 4 on the first surface 3a side is attracted to the wall surface W. , Between the main magnet 4 and the wall surface W on the second surface 3b side The operation for inserting the sheet S can be easily performed as.

  Further, since the secondary magnet 5 that can be attracted to the wall surface W by magnetic force is employed as the attracting means for suppressing displacement, the stationary member 2 can be stably attracted and supported on the wall surface W.
