Description

  The present invention relates to a magnetic fixing tool useful for holding a document or the like on a magnetic board or a steel desk. The present invention also relates to a sheet-like magnetic fixture that can be used as a print medium in addition to holding the document and the like.

  For example, when a paper piece is temporarily fixed to a saddle-shaped magnetic board or the like, the paper piece on the magnetic board is pressed from above with a block-like permanent magnet, and the paper piece is held by the magnetic attraction force. Usually, one side and the side of the magnet are covered with a plastic case, and a fixing tool is formed in an elongated bar shape for fixing a paper sheet such as A4. It is already known that a flat bar magnet having a length covering substantially the entire length of the bar is attached to one side of the bar. Also in this case, the side portion of the bar magnet is covered with a case that also serves as a makeup. However, as shown in Patent Document 1, in order to use the four side surfaces and both end surfaces of the case in the longitudinal direction as display surfaces, Also disclosed is a magnet bar that is fully contained within the case. In order to secure a large display surface of the case, the case is formed in a relatively large size with a rectangular body, and a small cylindrical magnet is movably mounted therein, and the case is made of a magnetic board or the like. When brought into contact with the magnetic plate, the columnar magnet rolls toward the magnetic plate in the case by the magnet's attractive force so that the case is attracted to the magnetic plate.

  As another example, as shown in Patent Document 2, there is known a paper piece fixture in which a concave portion is formed on one side of a transparent case made of acrylic resin, and a magnet is fitted through an adhesive layer colored in the concave portion. It has been. The magnet is usually grayish black or blackish brown in appearance, but it can be decorated by hiding the background of the magnet depending on the type of coloring of the adhesive layer, and the transparent piece of the paper piece that overlaps the fixing tool through the fixing tool. The written characters are visible.

  In addition, a horizontally long plate-shaped locking main body plate is provided with a slide plate that can be expanded and contracted, a magnet is provided near each end of the main body plate and the slide plate, and the slide plate is expanded and contracted or rotated to make a whole. There is also known a magnet-type fixture that can be changed in length or deformed into a bent L shape (Patent Document 3).

  As described above, this type of magnetic fixing tool uses a front surface and a side surface of the fixing device as a display surface for decoration or advertisement, for example, in addition to temporarily fixing a piece of paper to a magnetic board or the like. To get. However, this type of conventional fixture has a magnet exposed on or close to one surface of the fixture, and this surface has only a function of adsorbing to the magnetic board, and the exposed surface of the magnet is used as a display surface. It cannot be used facing the front (front). Also in the thing of patent document 2, the surface which a case adsorb | sucks is similarly limited to one side.

  The magnet bar shown in Patent Document 1 stores this point magnet in a case with a gap so that it can roll, and attracts any surface of the case by attracting and rolling the magnet against the mating magnetic plate. If the cylindrical body is used for smooth rolling of the magnet to be stored, the magnet is attracted to the mating magnetic plate at the generatrix of the cylindrical body, that is, in the state of line contact on the circumferential surface. Adsorption will occur, and sufficient adsorption power cannot be obtained. In addition, when a prismatic magnet having a wide side is used, the movement of the magnet is not smooth within the case, and not all of the plurality of magnets necessarily face the counterpart magnetic plate on the side of the prism. There is a problem that a powerful magnet must be built in to slide so as to be attracted by surface contact.

  Furthermore, when a bowl-shaped disc yoke or the like is attached to both end faces of the prismatic magnet to facilitate rolling in the case, a corresponding gap is created between the magnet and the case inner wall. There is a risk that a sufficient magnetic attractive force cannot be secured to the counterpart magnetic plate.

  Moreover, although the thing shown in patent document 3 which provided the small piece-like magnet in both the main body board and the slide board has the advantage which can change a full length and a shape by sliding the said slide board, it is a long board Since a small piece of magnet is exposed only at the end of the plate, the attractive force to the magnetic board is not sufficient, and the attractive surface is limited to one side, and the display function of characters, symbols, etc. on both sides of the long plate Can not have.

  An object of the present invention is to provide a magnet-type fixture that can use both the front and back surfaces of a case surrounding the entire magnet as magnetic adsorption surfaces, and the front and back surfaces and both left and right side surfaces of the case as display surfaces. To do.

However, in the present invention, the plastic case 3 is formed as thin as possible as a whole, and in particular, the thickness on the front surface side and the back surface side is reduced, whereby the distance between the magnet 2 in the case 3 and the magnetic board surface. Becomes smaller and a strong adsorption force can be obtained. The front surface 3a (front surface) and the back surface 3b (back surface) of the plastic case 3 are marked with graphics, symbols, characters, or the like. Therefore, for example, when the back surface 3b side of the magnet-type fixture 1 is attracted to the magnetic board, the indication (ABC in the illustrated example) attached to the front surface 3a is visually observed, and the front surface 3a side of the fixture 1 is When adsorbed on the board, the display on the back surface 3b (123 in the illustrated example) becomes visible. In some cases, not only the front and back surfaces of the case 3, but also the left and right side surfaces 3c can be used as suction surfaces. Therefore, by attaching the display to both side surfaces, the suction surface can be always changed by changing the suction surface with one fixture. The display on the opposite side surface is visually observed.

  In this way, the magnet-type fixture 1 of the present invention can have both the front and back surfaces along the longitudinal direction as a magnetic attracting surface and a display surface.

Of the magnetic pole 11 having a south pole and a north pole formed along the longitudinal direction. The distance L between the magnetic poles, that is, the N pole on the one surface in the longitudinal direction (the S pole on the back surface) and the S pole on the other surface on the other side (the N pole on the back surface) is increased. The lines of magnetic force are greatly outside and pass through the magnetic board. As in the case of FIG. 1, the thickness of the case surface 3a and the case back surface 3b, which are the suction surfaces of the case 3, are reduced, and both the front and back surfaces are used as display surfaces.

(Example 3)
FIG. 3 is a perspective view of a magnet type fixture 21 according to the third embodiment of the present invention. As shown schematically in FIG. 3, the prismatic magnet 22 accommodated in the non-magnetic plastic case 3 has N poles and S poles alternately in the direction of the opposite end surfaces of the magnets, that is, in the longitudinal direction of the prismatic magnet 22. Corresponding to this, S poles and N poles are alternately arranged on the back side. Even in the third embodiment, not only the front and back surfaces 3a and 3b of the case 3, but also the left and right side surfaces 3c can be used as suction surfaces. By changing, the display on the side surface opposite to the suction surface is always visually observed.

Example 4
In the above first to third embodiments, the integral prismatic long magnets 2 and 22 having substantially the entire length of the plastic case 3 are used. However, as shown in the fourth embodiment of FIG. 31 may be a short rectangular magnet 32 divided into a plurality of pieces in the longitudinal direction. The magnets 32 may be arranged so as to be in close contact with each other, or may be arranged with an appropriate interval. In this case, each magnet 32 may be fixed with an internal magnet, for example, by inserting a filling between the magnets so that the magnet 32 does not move in the case 3. It is the same as that of Examples 1-3 that a display is attached | subjected to the front and back of case 3, and the right-and-left side surface depending on the case. Moreover, in Examples 1-3, although the elongate magnet-type fixing tool which has a rectangular cross section was shown as an example, a block-type magnet-type fixing tool shorter than shown in Examples 1-3, and thickness of It is good also as a thin thin plate-shaped magnet type fixing tool. Further, a cylindrical or ring-shaped magnet may be used, and the magnet may be housed in a plastic case having a shape corresponding to these magnets to form a block-shaped, cylindrical, or ring-shaped magnet-type fixture.

The fifth embodiment is an example configured as a sheet-like magnet-type fixture 41 that can perform various types of printing on the front and back surfaces and can fix the writing on a magnetic board or the like. As shown in FIGS. 5 and 6, the magnet 42 of the present embodiment is formed of a thin and wide area sheet-like magnet. A print sheet 45 is adhered to the front and back surfaces of the magnet 42 so as to cover the entire front and back surfaces of the sheet-like magnet 42, thereby printing characters and symbols or various figures and patterns on the front and back surfaces 45a and 45b. It can be done. The print sheet 45 is fixed to the sheet magnet 42 by various fixing methods such as adhesion, pressure bonding, and heat bonding.

  The total thickness of the sheet magnet 42 and the print sheet 45 in Example 5 is about 0.5 mm as an example. The planar shape is preferably a square or a rectangular shape, but may be formed in other shapes such as a triangular shape, a circular shape, or any other planar shape. When the document is fixed to a magnetic board or the like, the sheet-like magnet-type fixture 41 is overlaid on the document on the magnetic board in the same manner as in the first to fourth embodiments, so that the document can be written with the magnetic attraction force of the fixture 41. To fix. Since both the front side and the back side of the print sheet 45 are printed display surfaces, the display side of the print sheet 45 can be visually observed both when the front side is applied to the magnetic board and when the back side is applied to the magnetic board.

  In the fifth embodiment, since the attracting surface of the sheet-shaped magnet-type fixture 41 is wide, it is advantageous for fixing a document having a large area. In addition, printing can be performed on both surfaces of the sheet-like magnet type fixture 41 by a printer or the like.
