Abstract

PURPOSE:To positively and easily perform center positioning for male and female stoppers by a method wherein a female stopper is directly locked by threadably attaching a protruding lever for engaging with the female stopper to the substrate of a male stopper in an engagement tool utilizing a permanent magnet. CONSTITUTION:A female stopper is composed of a ferromagnetic metal plate 3 and a ferromagnetic lever 3a protruded above the metal plate 3 face. The narrow lever portion of said lever 3a serves as a threaded lever section 3a' and is mounted and threadably attached to a substrate 4. In a male stopper, a ferromagnetic metal plate 2 is locked to the magnetic pole face of a magnet 1 with the aid of a case 4, and a washer 5 having legs 5a, 5a is also unitedly locked to the metal plate.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of a simple and reliable fastening means for a male stopper in an engaging tool using a permanent magnet.

Therefore, the bending-fastening male fasteners used in conventional engagement tools using permanent magnets are generally attached by a simple bending and crimping method to the board surface. Therefore, I tacking induced distortion or damage to the surface.

In other words, in the conventional method, when attaching the ferromagnetic rod of the male stopper, it was extremely difficult to align the position with the center of the magnet hole of the other engaging tool, and engagement was often used with a distorted board. This was thought to be the cause of unexpected disengagement from the engaged state or damage to the engagement platform.

In particular, during the center alignment 1; corners, since the previous male part 4 used a simple bending IF attachment method, the female stopper itself could not be installed between the boards due to the deviation of the center position. -C-induced withdrawal is often observed.

The engaging tool according to the present invention has been specially devised in view of the inconveniences in the prior art. By screwing the protruding rod that is inserted into the mating part to the board, it is directly fixed, making it easy to ensure center alignment between the four male studs, and also making it possible to securely and easily attach the male studs to the board. It has stronger adhesion.

A typical embodiment of the fastening tool according to the present invention is attached below.To explain the drawing of the elbow, (1) shows a hole a opened from one side of the magnetic pole face to the other side d tJj ifi. It is a permanent magnet, and is usually a sintered magnet such as a ferrite magnet, a steel magnet, a plastic magnet, or a rare earth magnet in a case where a particularly strong attraction force is required.

A ferromagnetic plate (2) is placed on one pole surface of the magnet (1).
) 2 cases (4) are held together and the legs 15) a and +5) a washer mounds) are integrally fixed to the plate (2).

The case (4) is usually made of a non-magnetic material and is shaped like a square.
The plate (2) is integrated with the magnet (1) by folding it onto the surface, and the hole edge (4)b, which is connected to the hole 11)a opened on the top surface, is connected to the hole (1)a. +h to align the holes of the fitting magnet (1).

The hole (1) in the plate (2) a has a ferromagnetic rod (2
) Raise the rod (2) a and attach the small diameter frame part of the rod (2) a to the plate 12);
It is inserted through a washer 6 (5) and the end is caulked.

In contrast to the female stop having the above configuration, the other male stop consists of a ferromagnetic plate (3) and a ferromagnetic rod (3) a protruding from the surface of this plate (3), The diameter rod portion 5 of the rod (3) a is a screw rod portion (31a') that is screwed onto the board (4).

In addition, in the example in FIG. 10, i+H2)a is omitted,
Correspondingly, the length of the tl131a of the 4th stop 4 is increased to reach the plate (2) surface through the hole (1)a, and the 11th
The fact shown in the figure is that a ferromagnetic plate for magnetic shielding (
6) was placed on the magnetic pole surface of the magnet ill, which serves as the attraction surface of the plate (3), to shield and capture the lines of magnetic force coming from the magnet 5(1), thereby suppressing as much as possible the destruction of the recorded portion of the magnetic tape, etc. It is a thing,
In particular, the periphery of the case (4) is raised to form a shoulder (4)C, which provides a reliable shielding effect.

Then the 121st. In this example, the case (4) is made into a droplet shape to effectively omit the case material and simplify the system fittings.
In the embodiment shown in Figure 4, the case (4) is completely omitted and the magnet (1) or ferromagnetic plate (6) is made of 479a body exposed on the outer surface of the surface layer. A magnet storage was used.

In addition, in the embodiments shown in FIGS. 15 and 16, a funnel-shaped or bottomed funnel-shaped crimping a (7) is used as a means for mounting by the crimping method, whereas a metal fitting (5) is used for top-up mounting. 2) was installed on the 1st floor, and the 17th
The example shown in the figure is a necklace in which the plate (2) is extended laterally to attach a chain, band, etc.
This figure shows an example of engagement with a bracelet, band, etc.

In the engagement tool having such a configuration, the male stopper (3) is attached to the surface of the plate (18) to form a mouth-shaped attachment that encloses the edge of the board (4), A ferromagnetic rod i:11 is attached with C so as to bend and attach the mounting plate (8) to the edge of the substrate (4).
a l Screw the screw part t31a' from the plate (3) toward the board (1) to connect the board (3) and the board (4).
8) so that they are integrally attached.

In addition, the material of the plate (8) used in this case is ferromagnetic.
Any non-magnetic material may be used, and the use of plastic materials other than gold is also planned.

In addition, the screw part -3)al in the rod (3)a is the substrate (4)
The shape and dimensions are specified by taking into account the material, thickness, etc. of the screw, and there are various types such as bolt-shaped ones, nail-shaped ones, and ones with a rounded tip. A bent plate (3) is prepared according to the purpose.
8) The case where it is screwed into part b is also planned.

Father, create a groove for engagement of each screwdriver at the head end of rod (3) a to match the screw insertion of rod (3) a, or
It was planned that a itself would have a bolt-like rectangular shape.

The engaging tool according to the present invention has four features as described above, including that the plate (3) is fixed and positioned using the rod (3) a and the plate (8); (3) without simply bending the rod (3)
The screw structure according to (a) makes it possible to obtain a concrete effect on the above-mentioned cord characteristics.

That is, when installing the plate (3), align the hole position in the nuclear female stopper after the decaccacide of the engaging female stopper with the plate (3).
), the engagement positions between the two are reliably matched, and poor engagement and other inconveniences can be effectively eliminated.

In addition, in the screw tightening method of 31a, it is not necessary to bend the plate (8) more than necessary, and the plate (3) itself may be distorted, dented, or covered by such crimping. This is what made 1s so painful.
