Description

Detailed Description of the Invention (Field of Industrial Application) This invention discloses a simple means for engaging on a wall surface, etc., and in particular, it is possible to minimize protrusions or protrusions on the surface of the engaging member when not in use, such as when hanging. The present invention relates to a wall surface engaging tool which is designed to ensure smooth use of the wall surface and also allows the engagement position to be freely changed.

(Prior Art) In the past, this type of engagement on a wall surface involved fixing a plate having a hanging hook such as a hook to the wall surface by gluing or nailing.

However, the above-mentioned hooks and the like have hooks and the like protruding from the wall surface in which they are used, which significantly impairs the decorative function of the wall surface, induces accidents such as getting caught, and significantly impairs the functional characteristics in the living room.

Therefore, Utility Model No. 53-7333, Utility Model No. 138266
A fixture using a permanent magnet was devised as disclosed in Japanese Utility Model Application Publication No. 49-138274.

(Problems to be Solved by the Invention) However, the above-mentioned fixture fixes a permanent magnet to the wall surface and attaches the hanging fixture by adhering it to the wall. It is very troublesome to fix by nailing, screwing, etc., or by using other attachment materials, and the surface to be fixed needs to be flat, or the surface to which gluing, nailing, etc. can be done is difficult. In addition to having restrictions such as the necessity of using it, there was also the problem that shocks and vibrations were transmitted as they were, making them easy to fall off.

(Specific Means for Solving the Problems) In view of the inconveniences in the conventional example, the wall surface engaging tool according to the present invention has one female stopper attached to the wall surface with adhesive and can be attached to this female stopper at any time. A ferromagnetic plate 2 is attached to the magnetic pole face b of a permanent magnet 1 having a hole 1a extending from one magnetic pole face a to the other weak pole face b. is attached, and the upper end of the ferromagnetic protrusion 3 erected on the ferromagnetic plate 2 in the hole 1a is substantially flush with the magnetic pole surface a, and the ferromagnetic plate 4 is mounted on the magnetic pole surface a. It is a wall surface engaging tool that is detachably attracted, and has a double-sided adhesive cushioning material 5 adhered to the non-adsorbed side surface of the ferromagnetic plate 2, and the permanent A retaining plate portion 4a bent at a right angle is formed to be engaged on the surface c between the magnetic pole faces a and b of the magnet 1, and a hook portion 4b is formed at the lower free end. It is a wall surface engagement tool.

(Embodiment) An embodiment of a typical engagement tool according to the present invention will be described below with reference to the attached drawings. A ferromagnetic plate 2 is attached to the magnetic pole face b of the permanent magnet 1, and this is integrally enclosed with a case 6 made of a non-magnetic material, and the ferromagnetic protrusion 3 is attached to the ferromagnetic plate 2. It is erected on the surface of the ferromagnetic plate 2 so that its upper end is substantially flush with the magnetic pole surface a. The ferromagnetic protrusion 3 can be fixed to the ferromagnetic plate 2 by caulking the rod end of the ferromagnetic protrusion 3, or by direct welding or other methods. Alternatively, the ferromagnetic plate 2 is squeezed out.

Next, a double-sided adhesive cushioning material 5 is pasted on the non-adsorption side surface of the ferromagnetic plate 2, and the release paper 7 of this cushioning material 5 is peeled off to fix the female fastener A of this structure to a wall surface 8, etc. I made it.

In contrast to the female stopper A constructed in this way, the male stopper B used by adsorption consists of a ferromagnetic plate 4 that comes into contact with the magnetic pole surface a of the permanent magnet 1, and an upper free end of the ferromagnetic plate 4. A retaining plate portion 4 bent at a right angle is retained on the surface c between the magnetic pole faces a and b of the permanent magnet 1.
a is formed, and a hanging hook part 4b is formed at the free end of the ferromagnetic plate 4, and the retaining plate part 4a and the hook part 4b are as shown in FIG. There are cases where the ferromagnetic plate 4 is directly bent and formed, and cases where the hook portion 4b is formed with other members as shown in FIG. 2.

In addition, the ferromagnetic plate 4 together with the engaging plate part 4a and the hook part 4b is used as a means of adsorption and as a decorative material.
Consideration is also given to the shape, material, etc. of the engaging plate portions 4a, 4b in accordance with the purpose.

Next, the case 6 of the female stopper A is usually structured to integrally hold the permanent magnet 1 and the ferromagnetic plate 2.
A hole communicating with is provided, and the edge of the hole is bent into the hole 1a to form an edge flange 6a, and a claw 6b is provided at the edge of the opening, and this claw 6b is folded onto the surface of the ferromagnetic plate 2, It was made to form an integral fastening.

In the embodiment shown in FIG. 3, a magnetic shield plate 9 is attached to the attracting surface of the permanent magnet 1 to prevent accidents caused by lines of magnetic force during engagement and use, especially for magnetic chips, cash cards, and other magnetic objects. It was designed to prevent the destruction of magnetic materials using records as content.

Next, the embodiment of the female stopper A shown in FIG.
The case 6 is simplified by making it cylindrical and having a rim 6c that comes into contact with the periphery of the magnetic shield plate 9. Magnetic plate 9, permanent magnet 1,
The ferromagnetic plate 2 is integrally held and fixed.

Next, the embodiment shown in FIG. 5 shows an example in which the above-mentioned case 6 is completely removed, and FIG. 6 shows an example in which the magnetic shield plate 9 is further omitted, and a plastic magnet or the like is usually used. .

(Effects) The wall surface engaging tool according to the present invention has the characteristic configuration described above, in particular, the female stopper A is adhesively disposed on the wall surface via the double-sided adhesive cushioning material 5, and the female stopper A
It is very easy to attach the wall surface engaging tool to the wall surface, and since the impact vibrations applied to the wall surface engaging tool are damped by the above-mentioned buffer material, it is prevented from falling off. Since the male stop B with a hook is attached to and detachably attached to the female stop A, it is not only possible to remove the male stop B when not in use, but also to attach the male stop B with a hook to the female stop A. Stop B can be used interchangeably.

In addition, the appearance characteristics of the female fastener A itself are not necessarily bad, and the aesthetics of the wall surface will not be damaged, and furthermore, the adsorption force of the female fastener A can be used to attach decorative plates when not in use. It can also be used for the purpose of adding an active decorative function by adsorbing and arranging them separately.

In addition, in the present invention, in addition to the hooking structure like a usual engagement tool, the engaged engagement plate portion 4
A is attracted towards the engaging end surface of the female stopper A to ensure that there is no room for the engaging member to fall off or cause looseness during use.

In particular, in the female stopper A according to the present invention, the ferromagnetic protrusion 3 is protruded substantially flush with the magnetic pole surface, which is the attracting surface, and is directly abutted against the ferromagnetic plate 4.
This also forms a reliable closed circuit for the lines of magnetic force, making the attraction function of the male stopper particularly reliable, and also serves to attract the lines of magnetic force on the attraction surface of the permanent magnet 1 to the ferromagnetic projections 3, thereby preventing magnetic leakage. This made it possible to effectively suppress the magnetic force and derive an effective adsorption function for magnets with the same amount of magnetic lines of force.
