Description

The present invention also relates again and again magnet-type fixed with the anti-slip function.

  Conventionally, for example, a magnet bar that fixes a document on a magnetic board using a magnet's attractive force, or a hook-like hanging member is attached to a disk with a magnet embedded on one side, and this disk is magnetically attracted to a magnetic wall plate. There is known a magnet hook for holding various articles on a wall plate by making them (for example, Patent Document 1). The magnet bar sandwiches one or more documents between the magnetic board and prevents the document from slipping off the magnetic board due to its magnetic adhesion, but the structure itself is one side of a prismatic long member. It has a simple structure in which a magnet is attached or embedded (Patent Document 2). As a main part of the magnet type fixing device, in addition to the elongate member, a member formed of a disk-like or rectangular piece member having a flat surface is widely known (Patent Document 3). Also, the front and back surfaces of the magnet are covered with a thin non-magnetic exterior sheet, and the exterior sheet is printed and used as a display surface, or the magnet itself is formed into a thin plate and a printed sheet is adhered to the surface. Also disclosed (Patent Document 4). In addition, there has already been disclosed a magnetic adsorption tool with a hook in which a non-slip material is directly attached to the outer periphery of a magnet that is exposed on the magnetized surface so that the magnet-type fixture does not slide off from a magnetic plate such as a magnetic board (Patent Document). 5).

  In addition to the anti-slip of the magnetic type magnetic adsorber, various anti-slip materials have been developed to prevent the furniture and furnishings installed on the indoor floor from shifting. For example, Patent Document 6 discloses a foamed body having a thickness of about 0.5 to 3 mm obtained by crosslinking and firing a mixture of an ethylene / vinyl acetate copolymer and an ethylene-propylene rubber as a non-slip material. In addition, a floor surface sticking sheet (Patent Document 7) in which a rubber adhesive is laminated and bonded to a transparent urethane resin sheet, a sheet material for electric and electronic parts, a touch panel surface material, and silicon that can be used as various non-slip materials A rubber composite (Patent Document 8) is also disclosed.

  Generally, a magnet used in a magnet-type fixture has a strong magnetic attracting force in a direction perpendicular to the magnetized surface, but a holding force in a direction parallel to the magnetized surface is weak. When a plurality of documents are sandwiched between them, there is a case where the magnetic fixing device is displaced from the magnetic board and the document holding is not effectively performed. If a stronger magnet is used to eliminate the slipping of the fixing tool, a large force is required when removing the document from the magnetic board, and it is inconvenient when the document is frequently changed.

  Moreover, in the form which relies only on the magnetic attraction force of a magnet type fixing tool, there exists a problem that fixing force is greatly influenced by the thickness of a to-be-adhered surface (magnetic surface), smoothness of a surface, etc. Although it is conceivable to apply a non-slip coating agent directly to the magnet itself of the magnetized surface with a conventional magnetic fixture, this method limits the types of coating materials and the surface of the magnet.

Has a main body. The magnetized disk member 11 of the main body has a magnet 13 fixed to the central portion of the externally exposed surface (magnetized surface), and has a non-slip function with rubber or a similar material on a part or all of the magnetized surface. A non-slip sheet 14 made of a urethane coating agent is attached. The non-slip sheet 14 is mounted so that the urethane coating agent is on the outer surface. The magnetic disk member 11 has a short shaft portion 15 protruding from a surface opposite to the magnetic surface, and a circumferential small concave groove is formed on the outer peripheral surface of the short shaft portion 15. The non-slip sheet 5 of this embodiment is manufactured by applying a urethane coating agent on the surface of a sheet-like rubber or similar material and curing it by, for example, UV irradiation. As the rubber or a similar material, resin rubber (synthetic rubber) such as chloroprene rubber, butyl rubber, nitrile butadiene rubber, silicon rubber, urethane rubber, etc. is adopted in addition to natural rubber. Moreover, as an example of a urethane type coating agent, the composition which has alkyd resin as a main component and mixed this with the hardening | curing agent and the polyisocyanate prepolymer is used. In this case, the rubber or similar material side of the non-slip sheet 5 is adhered to the magnetized surface of the magnet hook 10, and the surface of the urethane coating agent on the surface layer side is on the surface of the magnetized surface, that is, the outer surface of the magnetized surface. To be exposed.

And can be rotated freely. Since the hook holding member 12 and the magnetized disk member 11 are formed of a hard synthetic resin material, the short shaft portion 15 of the magnetized disk member 11 is forcibly pushed into the hook holding member 12 during assembly. Thus, the two members 11 and 12 can be assembled with a slight elastic deformation of the hook holding member 12.

  On the outer peripheral portions on both sides in the diameter direction of the hook holding member 12, arm portion insertion holes 18 of the hook 20 are formed. In this embodiment, the hook 20 is formed by bending a metal bar member into a hook shape. In the embodiment, the arm portion 21 is bent from the hooking portion 19 bent in a “square” shape or a “co-shape” to both sides along the outer shape arc of the hook holding member 12, and the tip end of the arm portion 21 is formed. The L-shaped tip 22 is bent into the L-shaped hook hole 18 of the hook holding member 12. With such a configuration, the hook 20 freely rotates around the axis of the hook arm insertion hole 18 of the hook holding member 12, and the hook holding member 12 has a central axis of the disk member 11 with respect to the magnetized disk member 11. It is freely rotatable around (that is, around the short shaft portion 15 of the disk member).

  The magnet hook 10 is magnetically attached to the magnetic plate by applying a magnetic attachment surface having the non-slip sheet 14 of the magnetic attachment disk member 11 to a vertical magnetic plate (not shown). In this case, the hook holding member 12 is Since it is rotatable with respect to the magnetized disk member 11, the hook 20 held by the hook holding member 12 rotates together with the hook holding member 12 so that the hook portion at the tip hangs downward under its own weight. Can be hung. Further, even when the magnetic plate magnetically attaching the magnet hook 10 is inclined obliquely downward, or when the magnetic plate is formed on a horizontal lower surface such as a ceiling plate, the hook member is a hook. Since it is rotatable with respect to the holding member 12, the hook portion at the tip hangs downward by its own weight, and the article can be suspended. Even when a heavy article is hung or hung on the hook member, the magnetic hook 10 is prevented from slipping off the magnetic plate by the anti-slip sheet 14 on the magnetic attachment surface.
