Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a magnet fixing tool, and more particularly to a magnet fixing tool for fixing to an iron plate tool or the like by utilizing magnetic force.

[0002]

[Prior art]

 Fixtures that utilize magnetic force, as shown in longitudinal section in Figure 2, for mounting objects on iron plate fixtures, such as steel furniture and other iron or steel articles, are quite common and widely used. Has been done. A conventional magnet fixture 50 of this type is such that one surface 54 of a disk-shaped permanent magnet 52 is mainly attached to an inner bottom surface of a circular tray 56 made of soft iron and the other surface of the magnet 52 is attached by using an adhesive or the like. The (exposed surface) 58 is fixed so as to be located inward of the top end surface 60 of the peripheral wall of the receiving tray 56, and the receiving tray 56 is bonded to the hollow holding member 62 made of a non-magnetic substance such as plastic. The exposed surface 58 of the permanent magnet 52 is exposed by using or by press fitting.

[0003]

[Problems to be solved by the device]

 As described above, in the conventional magnet fixture 50, since the top end surface 60 of the peripheral wall of the tray 56 projects outward from the exposed surface 58 of the magnet 52, the magnet fixture 50 is used for iron furniture or the like. If it is adsorbed on the surface or moved while adhering to the surface, the top end surface 60 of the peripheral wall of the tray 56 may damage the surface of furniture or the painted surface thereof.

Further, as described above, in the conventional magnet fixing device 50, the permanent magnet 52 and the receiving plate 56, and the receiving plate 56 and the holding member 62 are fixed to each other with an adhesive, respectively. When removing from the adsorption state, it is often the case that it is detached from the contact part and destroyed.

In view of these problems, the present invention does not damage the surface of the object on the other side that has been attracted during attachment / detachment or the like, and does not cause the magnet or the tray to separate from the holding member. To provide the ingredients.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the magnet fixture of the present invention is designed so that the top surface of the peripheral wall of the pan with the permanent magnet attached does not directly contact the surface of the object to be attracted. is there.

Further, the magnet fixture of the present invention is fixed to the holding member using the fixing member by a physical means without fixing the tray to which the magnet is attached to the holding member using the adhesive.

[0008]

【Example】

 Next, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of a magnet fixture 10 of the present invention. The magnet fixture 10 is composed of a disk-shaped permanent magnet 12, a circular flat saucer 14 made of soft iron for accommodating and housing one surface of the permanent magnet 12, and a permanent magnet 12 and the saucer 14. It is composed of a hollow holding member 16 molded of a non-magnetic substance, for example, plastic, which accommodates a solid body, and a fixing member 18 for attaching the combination of the permanent magnet 12 and the tray 14 to the holding member 16.

The disk-shaped permanent magnet 12 has a structure in which the top end surface 20 of the peripheral wall of the tray 14 is attracted to the other surface 22 of the permanent magnet 12, that is, the surface of the iron furniture or the like, like the conventional one. Also, it is projected to some extent to the outside.

The holding member 16 for accommodating the assembly of the permanent magnet 12 and the tray 14 projects from the inner surface of the bottom portion of the holding member 16 to mount the tray 14 in order to properly position the assembly in the holding member 16. A seat portion 24 to be placed is formed.

When the contour of the holding member 16 is circular, the seat portion 24 is preferably an annular shape that is concentric with the outer circumference.

The fixing member 18 for mounting the assembly of the permanent magnet 12 and the tray 14 in the holding member 16 is made of the same material as the holding member, and has a circular opening for exposing the attraction surface 22 of the permanent magnet 12 in the center. 26 is an annular member having 26.

The inner peripheral edge 28 of the opening 26 of the fixing member 18 has a thin thickness, and is radiated from the peripheral edge of the opening 26 so that the top end surface 20 of the peripheral wall of the tray 14 to which the permanent magnet 12 is attached is placed. It extends inward.

In this invention, the assembly of the permanent magnet 12 and the tray 14 is inserted into the holding member 16, and the fixing member 18 is fitted into the holding member 16 and pressure-bonded so that they are not separated from each other. To Therefore, a thick portion 30 is formed on the inner peripheral wall of the holding member 16, and when the fixing member 18 is fitted to the holding member 16 by applying force, the outer peripheral wall 32 of the opening 26 of the fixing member 18 is formed. Is prevented from being pressed by the thick portion 30 of the holding member 16 so as to cooperate with each other and to be separated.

If necessary, the holding member 16 and the fixing member 18 may be fixed to each other with an adhesive.

[0017]

[Effect of device]

 Since the magnet fixture 10 of the present invention is constructed as described above in detail, when the magnet fixture 10 is used by adsorbing it on the surface of steel furniture or the like as in the conventional one, the fixing member 18 is used. The inner peripheral edge 28 of the opening 26 contacts the surface of the other side to which it is attached, and the top end surface 20 of the peripheral wall of the pan 14 of the permanent magnet 12 does not directly contact the target surface. Therefore, upon attachment / detachment or movement, the top surface of the peripheral wall of the tray does not damage the surface of the other side, unlike the conventional magnet fixture.

Further, according to the present invention, the holding member 16 accommodates the assembly of the permanent magnet 12 and the tray 14, and the fixing member 18 is press-fitted or adhered to the holding member 16 so as not to be removed. Therefore, when used, the assembly of the permanent magnet and the tray does not come out of the holding member unlike the conventional case.
