  However, in the technique described in Patent Document 1, the rare earth magnet 9 in the center of the main body 8 is magnetically attracted in order to increase the magnetic attractive force and to magnetize the magnetic attractive surfaces on both sides to the display object. Since it is embedded over both sides of the convex curved surface, the manufacturing cost of the conventional magnet holder 7 is combined with the fact that the rare earth magnet 9 is thick and the expensive rare earth magnet 9 is used. There has been a problem that increases. Moreover, since the thickness of the embedded rare earth magnet 9 increases as the thickness of the main body 8 increases, there is also a problem that the manufacturing cost increases.

  On the other hand, in the technique described in Patent Document 2, a housing portion is provided in the casing 11, the permanent magnet 12 is movably installed in the housing portion, and the permanent magnet 12 is provided so as to be smaller than the housing portion. Although the amount of use of the permanent magnet 12 can be reduced, when removing the adherend piece 14 magnetically attached to the adherend surface 13 by the magnet bar 10, as shown in FIG. Since the permanent magnet 12 is free to move, that is, can move freely at the same time, the magnet bar is displaced on the inner peripheral surface of the casing 11 in an attempt to maintain the magnetic adhesion with respect to the rotation of the magnet bar 10, and the magnet The entire bar 10 is idle, and the magnetizing force of the permanent magnet 12 is maintained, so that there is a problem that the adherend piece 14 cannot be removed smoothly.

  Therefore, the present invention can reduce the manufacturing cost by reducing the amount of magnet used even if the thickness of the magnet holder increases, and can smoothly remove the memo paper or the like with one hand without the magnet holder spinning around. The issue was to provide a magnet holder.

In order to solve the above problems, the present invention is configured as follows. That is, the invention described in claim 1 according to the present invention, there is provided a magnet holder loaded with magnet holder body wrapped in two arcs curve, the said holder body, apexes of the two circular arcs curve loading of the hollow pillar is provided on the center line connecting, in the loading unit is characterized in that the magnet is mounted slidably.

According to the magnet holder of the first aspect of the present invention, since the magnet is slidable so as to move in the loading portion, the thickness of the holder main body is increased and the length of the hollow columnar loading portion is increased. Even if the length of the magnet becomes longer, it can be stably magnetized on both sides of the holder body while reducing the amount of magnets used, and when the memo paper is pulled downward to remove the magnetic memo paper etc. In addition, the magnet abuts against the inner peripheral surface of the loading portion, so that it is possible to prevent the magnet from moving away from the center line connecting the vertices of the two arcs of the holder main body on the inner peripheral surface of the holder main body. Therefore, it is possible to smoothly remove the memo paper or the like with one hand without the holder body spinning.

It is a perspective view which shows the other Example. It is sectional drawing which shows the magnet holder of a prior art. It is sectional drawing which shows the magnet bar of a prior art.

  Hereinafter, the present invention will be specifically described with reference to the drawings. First, FIG. 1 is a perspective view showing the structure of a magnet holder 1 according to the present invention, and FIG. 2 is a cross-sectional view of the magnet holder 1. The magnet holder 1 includes a holder main body 2, a loading unit 3, and a magnet 4.

  The holder main body 2 is formed in a disk shape in which two arc curves are combined by a nonmagnetic material. The loading unit 3 is formed in a hollow cylindrical shape on the center line connecting the vertices of the two circular arc curves, and the loading unit 3 is loaded with a magnet 4. The magnet 4 has a cylindrical shape that is slidable along the inner peripheral surface of the loading unit 3 inside the cylindrical loading unit 3, that is, a column having a slightly smaller diameter depending on the diameter of the loading unit 3. Is formed. The magnet 4 may have any shape and size as long as it can be loaded into the loading unit 3 formed in a hollow cylindrical shape. For example, if the magnet 4 slides in the loading portion 3 and the magnetic adhesion force on the magnetic attachment surface can be secured, the sheet 4 may be thin. If the space for the magnet 4 to slide in the loading portion 3 can be secured, an inexpensive low magnetic force can be obtained. The thickness of the magnet 4 may be increased.

  Next, the usage state of the magnet holder 1 configured as described above will be described. FIG. 3 is a cross-sectional view showing a usage state of the magnet holder 1. First, the memo paper 6 is pressed against the wall surface 5 that can be magnetically attached, and the memo paper 5 is clamped between the magnet holder 1 and the wall surface 5 and attached. Alternatively, the memo paper 6 may be attached so as to be inserted from below into the gap between the arcuate curved holder body 2 and the linear wall surface 5.

  The magnet holder 1 has a disc shape in which the holder body 2 is formed by combining two arc curves, so that the magnet 4 can be magnetically attached to the wall surface 5 by the arc curves on both sides. At this time, the magnet 4 moves toward the wall surface 5 side. The inside of the loading unit 3 is slid to magnetically attach the holder body 2 and the memo paper 6 to the wall surface 5. Further, since the magnet 4 is formed with a slightly smaller diameter according to the diameter of the loading portion 3, the magnet 4 can smoothly slide without being shaken inside the loading portion 3. The loading unit 3 is not limited to the above-described cylindrical shape, and may be an elliptical shape or a polygonal shape. Depending on the shape of the loading unit 3, the cross-sectional shape of the magnet 4 is the cross-sectional shape of the loading unit 3. If it is an elliptical shape, it is formed in a slightly smaller elliptical shape, and if it is a polygonal shape, it is formed in a slightly smaller polygonal shape, and it is formed into a shape that can slide smoothly and slide inside the loading portion 3. .

  Thus, by allowing the magnet 4 to slide inside the loading portion 3, the magnet 4 can be magnetized on both sides of the holder body 2. The wall surface 5 is a surface to be magnetized such as a whiteboard, a side surface of home appliances or furniture, a desk, a partition, etc., and the memo paper 6 is an example of a paper that is magnetized by the magnet holder 1 of the present invention. Any material can be used as long as it can be magnetically attached to the wall surface 5 by 1.

  FIG. 4 is a cross-sectional view showing a use state in which the memo paper 6 attached to the wall surface 5 by the magnet holder 1 is removed. In order to remove the memo paper 6 attached as described above, the memo paper 6 is moved by pulling it to the near side while holding the lower end of the memo paper 6 with one hand. Then, as shown in FIG. 5, the lower end of the holder main body 2 is inclined in the direction opposite to the wall surface 5, whereas the magnet 4 comes into contact with the inner peripheral surface of the loading portion 3, thereby causing the magnet 4 to move to the holder main body 2. Since the holder body 2 does not rotate freely on the inner peripheral surface of the loading unit 3 and the magnetizing force on the wall surface 5 of the magnet 4 is softened by the inclination of the lower end of the holder body 2, the holder body 2 is smoothly moved. The memo paper 6 can be removed.

  Since the magnet holder 1 is configured as described above, the magnet 4 loaded in the loading unit 3 does not detach from the center line of the arc curve, so that the memo paper 6 can be removed smoothly without the holder body 2 spinning around. Furthermore, since the magnet 4 slides inside the loading portion 3, the amount of the magnet 4 used can be reduced, and the manufacturing cost of the magnet holder 1 can be reduced. Further, it can be stably magnetized on both sides of the two arc curves of the holder body 2, that is, it is magnetized on the wall surface 5 with an arc curve opposite to the magnetized surface of the holder body 2 shown in FIG. Even if it makes it, since the magnet 4 slides to the wall surface 5 direction in the loading part 3, the effect similar to the above can be acquired.

  In the above embodiment, the holder main body 2 is formed in a disk shape wrapped with two circular arc curves. However, as shown in FIG. 6, the holder main body 2 is formed in a spherical shape, and the holder main body 2 is formed in the spherical holder main body 2. A hollow columnar loading unit 3 may be provided, and the loading unit 3 may be loaded with the magnet 4.

  In the above embodiment, the shape of the holder main body 2 is formed in a disk shape combining two circular arc curves. However, as shown in FIG. 7, the holder main body 2 is overlapped by tilting one of two substantially semi-cylindrical shapes by 90 degrees. It may be configured to be slidable by providing a loading portion 3 in the center and loaded with a magnet 4, and as shown in FIG. 8, two substantially semi-cylindrical shapes are stacked to form a pillow shape. Alternatively, the loading unit 3 may be provided in the center, and the magnet 4 may be loaded to be slidable. In this case, the holder body 2 is magnetically attached to the wall surface 5 at the center of the arcuate belly portion on both sides of the holder body 2.
