Description

[Detailed Description of the Invention] (Industrial Application Field) This invention discloses an engaging tool structure using a permanent magnet, which is provided as a method for securing an opening/closing part of a door, etc.
Particularly, an engaging tool in which one of the pair of engaging tools can swing in all directions to effectively solve the problem of poor engagement due to installation errors or distortion of the mounting surface due to use. Regarding the provision of

(Prior art) This type of conventional engagement tool called a catcher has a mounting surface attached to an opening of a product such as a cabinet with relatively little assembly dimensional error, so that it can be engaged. It was not necessarily necessary for the tools to be attracted to each other while swinging.

Particularly, in the case where a yoke is attached to both sides of a magnet, the yoke itself is swung to prevent movement of the engaging tool body as much as possible.

(Problem to be solved by the invention) However, in the actual production of cabinets, etc., dimensional errors are inevitable during production and assembly, and it is difficult to use the engagement tools in close contact with each other. There were many inconveniences in creating the situation.

This error in the installation level between the engagement tools was partially corrected by making the attached yoke swingable, but the direction of movement of the yoke was always in a fixed direction. It has been particularly difficult to correct the gap due to the mutual rocking of the engaging tools, which are oriented in all directions.

(Specific means for solving the problem) The engaging tool according to the present invention has been specially devised in view of the inconveniences in the conventional catcher, and has one side of the engaging tool having a permanent magnet. The structure is such that it can swing in all directions with respect to the installation level and effectively corrects deviations in engagement positions between engagement tools that occur during assembly, manufacturing, assembly, and use. The main point of
A ferromagnetic rod 2a standing upright within the hole 1a and a ferromagnetic plate 3 attracted to the magnetic pole surface a or a ferromagnetic rod 3a protruding from the ferromagnetic plate 3 are removably attracted within the hole 1a. In the engagement tool, one surface of the double-sided adhesive cushioning material is on the non-adsorption side surface of the ferromagnetic plate 2, and L
The other side of the mounting plate 5 is adhered to the letter-shaped mounting plate 5.

(Example) A typical example of the engaging tool according to the present invention will be described below with reference to the attached drawings. 1 has a hole 1a opened from one magnetic pole surface a to the other magnetic pole surface b. The magnet is a permanent magnet, and usually a bar steel magnet, a sintered magnet such as ferrite, a plastic magnet, or a rare earth magnet is selectively used when a particularly attractive force is required.

A ferromagnetic plate 2 is attached to one magnetic pole surface a of such a permanent magnet 1, and this is attached to a case 4 made of a non-magnetic material.
are integrally held and fixed to form a female fitting which is one of the engaging fittings.

Incidentally, this case 4 has a hole in the bottom surface of the inverted dish-shaped case that communicates with the hole 1a and has a flange 4a that engages with the edge of the hole 1a, and has a bent claw on the opening edge of the case 4. 4b integrally.

The ferromagnetic rod 2a is erected in the hole 1a of the permanent magnet 1 having such a structure, and the ferromagnetic rod 2a is strengthened by caulking, brazing, spot welding, gluing, screwing, or other appropriate methods. It is fixed integrally to the magnetic plate 2, and this is fixed to the end face of the mounting plate 5 via a double-sided adhesive cushioning material 6.

The adhesive cushioning material 6 itself has sufficient elasticity and elasticity, and can freely tilt by an amount equivalent to the thickness of the cushioning material 6 relative to the tilting of the fixed engagement tool. The engaging tool can swing in all directions, effectively correcting dimensional errors and mounting distortions in the mounting part of the cabinet, etc., and ensuring proper adsorption. shall be.

The mounting plate 5 is usually fixed to an opening of a cabinet, etc., and is approximately L-shaped, with one bent end surface attached to the cabinet surface with screws,
It is fastened using wooden screws, nails, or other suitable methods.

The male tool, which is the other engaging tool, is made up of a ferromagnetic plate 3 and a ferromagnetic rod 3a, and is assembled using an appropriate method.
For example, it is attached to the cabinet door by gluing, riveting, nailing, screwing, etc.

In the embodiment shown in FIG. 2, the length of the ferromagnetic rod 2a is up to the opening end surface position of the hole 1a of the case 4, and the male tool is attached to the peripheral edge of the ferromagnetic plate 3 instead of the rod 3a.
It has a raised structure.

Next, the embodiment shown in FIG. 3 is an embodiment in which a ferromagnetic plate 7 is provided inside the case 4 of the previous embodiment, and is intended to further enhance the magnetic shielding effect. Incidentally, if the peripheral edge of the end surface of the case 4 that comes into contact with the ferromagnetic plate 3 is raised to form a rising shoulder, the shielding effect can be further ensured.

By the way, in the embodiment shown in FIG. 4, the permanent magnet 1
By using a plastic magnet to eliminate the fragility peculiar to magnets, the case 4 and the ferromagnetic rod 2a are also omitted to reduce manufacturing costs.
In addition, the embodiment shown in FIG. 5 has a ferromagnetic plate 7 on the surface of the permanent magnet 1 for the purpose of protecting the surface and preventing destruction of the magnetic recording portion of the magnetic tape or the like due to the magnetic field lines of the magnet used. is attached.

There are various methods for attaching the male fitting.
The ferromagnetic rod 3a is attached to the ferromagnetic plate 3 by welding, brazing, caulking, gluing, or other methods, and the ferromagnetic plate 3 itself is also attached to the substrate surface by gluing, riveting, bending, or fixing. It is fastened using a suitable method such as nailing or screwing.

Furthermore, various other design changes are made in the structure of the female fitting, especially in the shape of the case, the method of attachment, etc.

(Effects) The engaging tool according to the present invention is constructed as described above, and the female tool, which is one of the paired engaging tools, is adhered to an L-shaped mounting plate of a cabinet or the like using a double-sided adhesive cushioning material. Because of this, the female fitting can swing and tilt in all directions with respect to the mounting surface, and there may be deviations in the relative positions of the male fitting and female fitting due to the manufacture, assembly, and use of the cabinet, etc. is also appropriately corrected and effectively engaged.
