Abstract

PURPOSE:To maintain the magnetic closing circuit even at oscillation of a male engaging member, by a method wherein length of a ferromagnetic lever as a male engaging member of the engaging device is made greater than depth of a hole of a magent as a female engaging member. CONSTITUTION:A permanent magnet 1 has a hole 1a, and a ferromagnetic plate 2 is attached to one pole surface of the permanent magnet 1 and fitted to a non- magnetic case 4 integrally. A ferromagnetic plate 3 is abutted to other pole surface of the permanent magnet and detachably connected by magnetic force. A ferromagnetic lever 3a with diameter greater than depth of the hole 1a and smaller than diameter of the hole 1a is projected from center portion of the plate 3. In this constitution, when the engaging device is installed to a handbag or the like, toughness of leather as raw material produces yielding to the engaging device by external force and lateral shift, however, force of pulling the lever 3a itself from the hole 1a is eliminated by a gap of the lever 3a for free inclination or oscillation, thereby failure of the engaging is prevented.

Description

[Detailed Description of the Invention] This invention relates to a connection structure in a bonding device using permanent magnet gold, and in particular, the length of the ferromagnetic rod of the male engagement tool. The present invention relates to the disclosure of an engaging tool that is longer than the depth of the hole provided in the true magnet hole and has a wobble that allows the magnetic closed circuit to continue even when the male tool swings.

In the conventional retaining device for this type of lock, the length of the ferromagnetic rod on one side of the engaging device is equal to the depth of the hole in the other magnet, and the length of the ferromagnetic rod on one side of the engaging device is equal to the depth of the hole in the other magnet. When attached to a handbag, etc., due to the strength of the leather material, the lid of the handbag may be pushed by external force, and the ferromagnetic material inside the engagement tool may tilt or swing due to distortion of the lid. This is due to the fact that it separates from the ferromagnetic plate and breaks the magnetic closed circuit, causing it to easily come off and become loose.

The present invention was devised especially in view of the inconveniences in the prior art, and one of its main purposes is to prevent bags with retainers attached from being pushed around, for example, in crowded trains. The lid is guarded to prevent it from opening easily when the lid is opened.

Next, one of the other main objects of the present invention is to make the length of the ferromagnetic rod t-la longer than the depth of the stone hole. This avoids the risk of contact with the magnetic plate and is easy to manufacture.

Accordingly, the present invention provides a permanent structure in which the hole (1)a is opened from one magnetic pole surface to the other magnetic pole surface in order to achieve appropriate and purposeful effects on magnetic properties. The ferromagnetic plate 121 is properly attached to one of the magnetic pole faces of the magnet +1), and the ferromagnetic plate 121 is removably abutted to the other magnetic pole face (protruding from the plate (3)). ferromagnetic rod 13
] In an engaging tool in which a is magnetically and removably brought into contact with the surface of a plate 12) through the hole (1) a, the length dimension of one ferromagnetic rod 13) a of the retaining tool. The hole 1118G of the rod (3)a should be greater than the depth dimension of the hole 11)a, and when the hole 1118G of the rod (3)a comes out, the chain plate 13) should be placed between the abutting pole faces of the plate 131 and the magnet 11). In keeping with the gist of this configuration, a design equivalent to r is made, in which the ring diameter is reduced compared to the hole diameter of hole tl) and hole tl) so as to leave a tilting and oscillating gap. change? This is something I had planned.

The details of the present invention will be described below with reference to drawing numbers and a typical embodiment.The present invention is described below using a donut-shaped permanent magnet with a hole 11)a opened from one magnetic pole surface to the other magnetic pole surface. , the magnet! 1) One magnetic pole [iiG strong e & sex plate 12
) is attached and attached, and the magnet 11) and chain plate 12) are magnetized integrally. ! 11. The ferromagnetic plate 13+ is fitted and fixed by a case 14) made of material, and the ferromagnetic plate 13+ can be freely attached and detached so as to come into contact with the non-fixed magnetic pole surface of the ferromagnetic plate 12) of the magnet 11). In the center of the chain plate (3), a strong abrasion rod 131 a f, which is longer than the deep dimension of the hole (1) a, is protruded.

The present invention has a unique structure in soft soil, especially magnet hole Ill.
The ferromagnetic rod 131 a longer than the depth dimension of II can be effectively corrected by protruding from the ferromagnetic plate 131. It was hoped that the drug would be effective.

That is, in the present invention, when the ferromagnetic plate 13) is attached to a bag, handbag, etc., the ferromagnetic plate 13) a becomes plateless due to the bending and lateral displacement of the engaging part due to external force due to the strength of the leather material, etc. (An inclination occurs with respect to 21, and the depth dimension of the magnet hole (1) a and the chain ring 13
) Since the lengths of a) are the same, the shortcoming is that the engagement tool comes off when the plate 12) and rod 13) a separate.
This problem was effectively solved by making the rod 131a t'' longer than the depth of the hole a.The ring diameter was made shorter than the hole diameter, and the tilting and swinging of the rod 131a was provided. Even when the lid of a bag or the like is bent or shifted laterally, the rod 131a tilts and oscillates, thereby eliminating the force that tends to pull the rod 13a itself out of the hole Illa. In this case, as mentioned above, it is not required that the depth of the hole/lea where the chain ring 13)s fits is the same as that of the hole/lea, so the effort of creating dimensional accuracy can be omitted. It was possible to achieve the entire project at a low cost of 1 work.

Now, to explain another embodiment of the present invention, in FIG. Something with smooth rocking.

It has good adaptability to the movement of the lid of a bag, etc. As shown in Figure 1, when the end of the rod 13)a is made completely flat and when it is made spherical, the amount of magnetic force lines passing through is the same, so there is no difference in the magnetic force as an engaging tool.) It is something.

In FIG. 3, ll1 is in contact with the chain plate 131 for the magnet.
Ferromagnetic plate (5) for surface flea shielding is attached to the pipe to improve the magnetic shielding effect.

Also, #憚1318? The rice 131 and the leg piece vI - washer <6) are integrally attached with a guard I. Washer 161 attached to the plate 12)? Case 14) It's a first-come-first-served basis compared to Kukko/! S.

Note that the washer (6) is the one for which spot welding, brazing, or adhesion other than the above methods are planned for the plates 12) and 13). One protrusion is provided on the upper end,
By providing a sufficient magnetic gap t-vr when making contact with a magnetic recording card, magnetic cap, etc., destruction of the magnetic recording portion due to some leakage magnetism is reliably prevented.

11!5 The upper part of the surrounding sand of the ferromagnetic plate (5) is completely shaved, and it is used as the retaining part of the upper end of the case 14), and the cough engaging part is on the same plane as the F side of the chain plate 15). It was made so that it would become so.

As in the case of soft soil, the present invention relates to an engagement tool (in a related connection structure, the length of the ferromagnetic rod of one of the engagement tools is longer than the depth dimension of the other magnet hole, and the tilting and oscillation of the chain ring is The object of the present invention is to provide a highly effective engaging tool that continues to be magnetically attached even during motion.
