Description

[Detailed Description of the Invention] Field of Application of the Invention The present invention provides a stopper using a permanent magnet, in particular a ring spring is installed inside the female deodorizer, thereby making it possible to further improve the engagement property of the stopper. This invention relates to the disclosure of an extremely novel and effective fastener structure.

BACKGROUND ART Fasteners using permanent magnets are widely used as fasteners for bags, etc. because they are easy to engage and detach.For example, permanent magnets with a through hole from one magnetic pole face to the other A ferromagnetic member fixedly attached to one magnetic pole face of the magnet and a ferromagnetic member abutted to and attracted to the other magnetic pole face attach and detach the ferromagnetic protrusion of each ferromagnetic member through the through hole. It is designed to be absorbed freely.

Problems to be Solved by the Invention However, the above-mentioned fasteners are engaged by the attractive force of a permanent magnet, and are not particularly mechanically engaged, so they are easily disengaged. In addition, there was a problem that the lever-like force acting on the magnetic pole surface was particularly weak.

Means for Solving the Problems The present invention has been proposed to solve the above-mentioned problems, and one of its first objects is to use the attractive action of a permanent magnet, as compared to a conventional elastic engagement member. The second purpose is to provide a more stable magnetic toilet stopper compared to the usual permanent magnet toilet stopper, in that the male stopper can be reliably and smoothly attached to the bag by attracting it into the female hole. It is possible to create the attached state by using the ring spring of the insert bag. That is, when the male stop is detached from the magnetically attached end surface, the continuous elastic force of the ring spring causes the male stop to spring again in the direction of the magnetically attached surface. This makes it possible to guarantee remagnetization, and the third purpose is to make the auxiliary structure described above a simple ring spring interposed structure, to simplify the structure and reduce manufacturing costs. Furthermore, the fourth purpose is that when the engagement member is used, the presence of the ring spring makes a snapping sound, which makes the feeling of use more reliable. By using a ring spring as well as an eggplant, it is possible to more reliably simplify the appearance, and the stopper using a permanent magnet is directed from one magnetic pole surface a to the other magnetic pole surface b. A ferromagnetic member 2 is attached to one magnetic pole surface a of a permanent magnet 1 having a hole la, and a ferromagnetic member 9 consisting of a ferromagnetic plate 9a and a ferromagnetic protrusion 9b is supported on the other magnetic pole surface b. , in the engaging tool detachably attracted in the hole la of the permanent magnet 1, the vicinity of the opening □ of the hole la of the permanent magnet 1 is a circumferential recess la', and a ring spring is fitted in the circumferential recess la'. 5 is inserted into the tip 9 of the protrusion 9b of the ferromagnetic member 9.
The injury is an enlarged head, and the ring spring 5 is in contact with the ferromagnetic member 2 and the head is attracted to the ferromagnetic member 2.

EXAMPLE Hereinafter, a typical example will be described in which the details of the present invention are shown in the drawings. 1 is a permanent magnet having a substantially cylindrical shape,
On the other hand, the permanent magnet 1 has a ferromagnetic member 2 adsorbed and attached to the magnetic pole surface a so as to close the hole 1a of the permanent magnet 1, and has a bottom engagement hole 3a whose diameter is smaller than that of the hole 1a. The ferromagnetic member 2 is fixed to the permanent magnet 1 using the engaging pieces 3b to 3b of the case 3.

Incidentally, when this fixing is done, the mounting plate 4 with the engaging pieces 4a to 4a bent and formed is fastened at the same time to create the basic shape of the female fastener, and then it is fitted into the hole 1a and the green of the hole 3a is fixed. A cylindrical support frame 6 having a longitudinal diameter in the direction of the ferromagnetic member 2 is iron-mounted to form a free iron gap for the ring spring 5 between the ring spring 5 and the flange 3a'.

In contrast to such a basic case, the embodiment illustrated in FIGS. 3 and 4 is one in which the above-mentioned green collar 3a' is created in the magnet 1' body, and as a matter of course, However, the case 3 is not required and the mounting fabric 7 for bags etc. can be used instead.
Insert the bolts 8 to 8 etc. through the ferromagnetic member 2,
This is fixed to the magnet 1', and a green collar 1'a' is integrally provided on the edge of the entrance of the hole 1'a, and this green collar 1' is fitted with iron inside the hole 1'a. The ring spring 5 is suspended between a ring-shaped support frame 6' having a relatively large diameter.

Note that various materials can be used for the mounting means and the permanent magnet 1 in the above configuration.

To explain one embodiment of a typical male stop that is used in engagement with the structure of the female stop mentioned above, the ferromagnetic member 9 is composed of a ferromagnetic plate 9a and a ferromagnetic projection 9b, A ferromagnetic plate 9a that is magnetically attached to the magnetic pole surface b of the magnets 1 and 1' during engagement and disengagement operations.
and a mounting plate 10 formed by bending and forming locking pieces 10a to 10a for the mounting fabric 7, with a ferromagnetic protrusion 9b that is magnetically attached to the ferromagnetic member 2 through holes la and 1'a. The ferromagnetic protrusion 9b is basically an enlarged head 9b' with a smooth surface.

The ferromagnetic member 2 that is attached to the magnetic pole surface a of the permanent magnet 1 of the female stopper is not only plate-shaped but also consists of a ferromagnetic plate 2a and a ferromagnetic protrusion 2b, so that the engagement of the female stopper is on the magnetic pole surface b. In some cases, the ferromagnetic plate 9a of the male stopper is attracted to the ferromagnetic plate 9a, and the ferromagnetic protrusions 9b and 2b are attracted within the hole la of the permanent magnet 1, so that they are engaged.

Effects The present invention has the above-mentioned characteristic configurations, particularly permanent magnets 1,
By inserting the ring spring 5 into the holes la and 1'a of the female stopper using the holes 1' so as to be able to expand and contract elastically, the above-mentioned characteristics can be achieved in a concrete manner. be.

By interposing the ring spring 5 as an auxiliary engagement means for the magnetic attachment of the permanent magnets 1 and 1', when the magnetic pole surface shifts or loses due to vibration etc., the foundation is forced to redirect in the magnetic attachment direction. This makes it possible to maintain an accurate magnetic attachment state, and when engaged, the magnetic attraction force is used to smoothly attract the attachment direction, and this magnetic attraction force is used to resist the elastic force of the ring spring 5. This system particularly guarantees a tight alignment, and at the same time generates a snapping sound when magnetically attached, which is particularly effective in confirming engagement during use.
