Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener with magnets for use as a fastener for accessories such as necklaces and bracelets and as a fastener for clothes, bags and the like.

[0002]

2. Description of the Related Art Conventionally, as a fastener for an accessory such as a magnet, a connecting tool disclosed in Japanese Utility Model Laid-Open No. 1-90410 and an end fitting structure for an annular accessory disclosed in Japanese Utility Model Publication No. 6-36744. Etc. The former coupling tool is one in which a magnet is fitted into a pair of flat tubular metal fittings, and the ends of the necklace are coupled to each other by the magnetic attraction force of the magnet.

On the other hand, the latter end fixing structure is provided with a holding plate for fixing the fitting positions of these magnets when a plurality of magnets are fitted into a pair of flat tubular metal fittings. Each magnet is inserted into a through hole penetrating the holding plate, and the magnet is fitted together with the holding plate into a flat tubular metal fitting.

[0004]

However, these conventional stoppers using magnets have the following problems. That is, both of the magnets fitted into the pair of flat tubular metal fittings exert the magnetic attraction force at the positions where the magnetic poles are different, but when both magnets have the same magnetic pole, the repulsive action occurs. Moreover, when a plurality of magnets are fitted into the flat tubular metal fitting, since the magnetic poles of adjacent magnets are arranged in opposite directions, both magnets are placed next to the position where both magnets are magnetically attached. It will be placed in a repulsive position. Therefore, conventionally, the repulsive position is used to remove the magnetized magnets from each other.

However, the magnetic attraction force of the magnet shows a strong magnetic attraction force in the direction of separating the magnetic attraction surface, but the magnetic attraction force in the direction of rotating the magnetic attraction surface is weak. Even if they were not rotated, both the tubular metal fittings in the magnetically attached state might rotate by some kind of momentum. If both magnetic poles coincide with each other against your will, both magnets that were firmly attached until then will repel,
Not only may the connection be suddenly released, but the accessory may also pop out of the body. As described above, since the conventional fasteners using magnets lack the certainty of the connected state, there is a concern in using them as the fasteners for jewelry using high-grade jewelry or precious metals.

[0006] Therefore, there is proposed a stopper having a structure in which both cylindrical metal fittings in a magnetically attached state are prevented from rotating due to some kind of moment like the stopper described in Registered Utility Model No. 3055446. On the contrary, it has been found that there is no function to remove the magnetized magnets by utilizing the repulsive position, which makes the removal operation difficult.

Therefore, the present invention has been devised to solve the above-mentioned problems, and in a magnet-equipped stopper using a magnet, it does not come off against the intention of the user, and the operation is simple. The purpose is to provide a removable stopper with a magnet.

[0008]

In order to achieve the above object, a stopper with a magnet of the present invention has a built-in magnet in which different magnetic poles are arranged side by side, and one side of the magnetic pole is opened, and an opening portion The female side housing has a slide groove formed toward the other magnetic pole side, and the male side housing has a magnet having the same magnetic pole as the opening side magnetic pole and has a slide guide attached. Insert the magnet of the above into the female side housing from the above opening and slide it from the opening toward the other magnetic pole side to attract different poles.When removing, slide the magnet in the male side housing toward the opening and It is characterized in that the repulsion force of the magnetic poles is utilized to facilitate the detachment.

The stopper with magnet of the present invention is also characterized in that the magnet having the different magnetic poles arranged in parallel has a pair of different magnetic poles arranged in parallel in one magnet.

The stopper with a magnet according to the present invention is also characterized in that the magnet having the different magnetic poles arranged in parallel has two magnets having the different magnetic poles arranged in parallel.

The stopper with a magnet of the present invention is also characterized in that the slide guide has a function of preventing the female housing and the male housing from being twisted.

Since the present invention is configured as described above, a magnet stop using a magnet is provided which does not come off against the intention of the user and which can be attached and detached by a simple operation. I was able to do it.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a case where an embodiment of a stopper with a magnet of the present invention is used as a stopper for a string-like accessory such as a necklace and a bracelet, a stopper for clothes, etc. The details will be described. 1 is a schematic sectional view of a male side housing used in one embodiment of a stopper with a magnet of the present invention, FIG. 2 is a plan view thereof, FIG. 3 is a schematic sectional view of a female side housing, and FIG. 4 is a plan view thereof. 5, FIG. 5 is a schematic cross-sectional view of a state in which both are assembled, and FIG. 6 is a plan view thereof.

In FIGS. 1 and 2 showing the structure of the male side housing, a flat magnet 2 is housed and held in the male side housing 1, and different magnetic poles (N pole, S pole) are provided on both sides of the magnet 2. Are arranged. Further, 3 is a strip-shaped slide guide that is provided on the outer peripheral side of the magnet 2 and has a function of preventing twisting, 4 is a chain, and 5 is a knob used when attaching or detaching.

Next, referring to FIGS. 3 and 4 showing the structure of the female housing, a pair of front and rear flat magnets 12, 13 are housed and held in the female housing 11 in the lengthwise direction thereof. Different magnetic poles (N pole and S pole) are arranged on both sides of the magnets 12 and 13, and the magnetic poles of the magnets 12 and 13 are also different on the front and back sides. That is, in the magnet 12, the upper surface side is the N pole, and in the magnet 13, the upper surface side is the S pole.

Further, in the drawing, 14 is a male side housing 1
The magnet 12 is an opening formed in such a size that the magnet 2 is fitted therein, and the magnet 12 is arranged at a predetermined interval from the opening 14 in the opening 14 portion. A slide groove 15 is formed in a slit shape from the opening 14.
