Description

[Detailed Description of the Invention] The present invention provides a retaining tool 1 using a permanent magnet, particularly an engaging tool with a magnetic shielding effect, and a simple mounting method for this retaining tool. Assembly is related to the disclosure of the structure.

However, in the conventional rice engaging devices, the magnets used (the action of magnetic lines of force) caused various obstacles, especially (
Destruction of the magnetic recording parts of magnetic clips, magnetic tapes, magnetic cards, etc. is a problem, and when installing the engaging tool itself, the installation of folding legs, etc. (In this way, the direction of insertion of this leg is determined, and the position in the upper surface direction of the engaging tool is specified, and it is impossible to actually correct this position.) When installing the joint plate, insert the washer,
Complicated installation work such as folding was required.

In particular, accurate positioning with respect to the mounting surface is important when the engaging tool to be installed is cylindrical or disc-shaped.
(Although this is not a problem, if the shape of this engaging tool is square or oval, etc. (in this case, the shape of the engaging tool may be square or oval). Careful installation was required by the operator. It is almost impossible to remove the tool and re-insert it, as it will damage the fabric of handbags, etc., and damage the surface of the fabric. This poses a structural difficulty in that the lining fabric is sewn together with the outer fabric after the retainer is attached to the outer fabric.

In addition, in the case of the bending leg structure in the conventional example, if there is a misalignment in the fitting position or direction with the other engaging tool, this will make correction almost difficult and the installation will be difficult. Accuracy in the work is particularly important.

Hereinafter, a typical embodiment of the engaging tool according to the present invention will be explained with reference to the attached drawings. One magnetic pole surface of this permanent magnet (1) is equipped with a ferromagnetic plate (2), and the other magnetic pole surface is equipped with a hole that communicates with the ferromagnetic plate (2).
3) Add a ferromagnetic plate (3) having a
), (3) and the magnet (1) are held together with a tape (4) so that they are fixed in one direction.The tape (4) has holes (31a, (Ila i) A hole (4) made of an inverted dish-shaped non-magnetic material with a hole (4) a formed on the bottom surface and having a row of bending lines that corresponds to the inner wall surface ζ of the annular hole fil a, f3) a. It is.

The plates (21, (31) housed inside the tape (4)
The magnet (11) connects the line row of holes (4) a in the case (4) to the hole + I181 (3) a 4, and attaches the hole to the hole (4) a position of this tape (4). +118, (31
Positioning is done so that a is located, and then the tape (
The claws (4)b provided on the opening edge of 4) are bent and pressed onto the surface of the plate (2) so that they are integrally held.

Next, a ferromagnetic plate (5) to be adsorbed by this suction tool Al and the removable plate is separately prepared, and a ferromagnetic plate (5) and a plate (2) in the previous hole (IIH) are attached. The ferromagnetic rods (6) are each erected, and the structure is such that during the standing process (6) they attract each other in a manner that they can be freely engaged and detached from each other within the hole. The small diameter frame part (6) a that can be attached to the plate (2), (
The hole (2+a) of (5) is cut so that it protrudes from the other side (51a) so that it can be pushed through to attach the rod (6).

In contrast to the suction tool A and plate (5), it was planned that a means would be separately attached to it, and the means for this attachment would be the planographic plate (7). A funnel-shaped swaged pipe (8) with a horizontal extension collar (8)
8), and the circumferential edge of the expanded collar (8) b at the pipe (8) l is held together by a force Q (a force Q is applied to the circumferential edge folded locking collar (which is clamped together with a force a). .

For such attachment, the method is to plate t21, (51ifl), insert the thin diameter frame part (6) a of the previous rod (6) into this flat plate (the hole (7) opened on the force side). Attach it by inserting it through the & (7).
The end of the frame (6) a protruding inward is held by a caulking rod inserted from the opening surface of the tube (8), and the plate is φ-shaped so as to be crushed and caulked on the force surface.

The present invention is intended to achieve various effects on the above-mentioned physical properties due to the characteristic configuration of the slanted structure, and the tube (8) is simply inserted into the substrate, Base the end 11
+C caulking, interposing a washer, and shimming, or separately preparing a funnel-shaped caulking tube part that fits or fits into the stacking tube (8). Press-fit the caulked pipe member from the other side of the board and fasten it 1-
It is planned that it will be secured by appropriate means such as

Therefore, the tube (8) can be installed freely with this tube (8) as the axis. Assuming that 1. The problem has definitely been resolved.

Furthermore, since the crimping is done by Tt (81kl), it is possible to change the orientation to some extent even after installation without having to remove the retainer.

Next, magnetic shielding is guaranteed by the interposition of the plate (31), and since the sufficiently shielded plate (3) is further covered with a non-magnetic case (4), the A side of the suction tool is Even if a member with magnetic recording content such as a magnetic tape or a magnetic kip comes into direct contact with the plate, the recorded content is prevented from being destroyed, and even when the plate (5) is not attracted. It promises magnetic shielding.
