Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a magnetic closure for items such as clothing.

[0002]

It is known that so-called magnetic closures have been commercially available for a long time. Such closures are commonly provided by an annular permanent magnet associated with a disk having pins made of a ferromagnetic material that is substantially intended to concentrate magnetic flux lines, improving the effectiveness of the magnetic closure.

[0003] Since these magnetic elements contain iron components which are unavoidable at the time of wet cleaning or dry cleaning, they penetrate by water and moisture, and
Cannot be used on clothing.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a magnetic closure for items such as clothing that can be hermetically sealed to separate the magnetic body, thereby completely preventing the penetration of water and moisture. It is to solve the above problem by providing.

[0005] Within the scope of this object, a special object of the invention is to provide a magnetic closure which is easy to connect to items such as clothing by heat sealing or sewing.

Another object of the present invention is to provide a magnetic closure capable of freely adjusting the magnetic attraction between the parts to be joined.

[0007] Another object of the present invention is to provide a magnetic closure which, by virtue of its special structural features, can provide the best reliability and safety during use and is also competitive from an economical point of view. To provide.

[0008]

In order to solve the above technical problems, the present invention provides a magnetic closure for items such as clothing having the following structure.

That is, the present invention comprises a magnetic body adapted to a sheet formed by two plate-like elements which are hermetically sealed and interconnected at least in an area surrounding the periphery of the magnetic body, said plate-like elements being combined Is applied to each of the two flaps to be joined.

[0010] Further features and advantages of the present invention will become apparent from the following detailed description of a preferred, but not exclusive, embodiment of a magnetic closure for items such as clothing. They are shown as non-limiting examples in the accompanying drawings.

[0011]

Embodiments of the present invention will be described with reference to the accompanying drawings.

Referring to the above figures, a magnetic closure for an item such as clothing according to the invention comprises a magnetic body indicated by reference numeral 1. It is constituted by a permanent magnet 2 which is advantageously associated with a metal plate 3 from which a pin 4 intended for magnetic flux concentration projects.

A special feature of the invention is that the magnetic body 1 is adapted to a sheet 5 which is sealed to the outside, and is provided with two plate-like elements 10 provided by a calendered synthetic resin material forming a thin layer. , 11 means that they are actually formed.

The plate-like elements 10, 11 are interconnected with at least a region 12 surrounding the magnetic body 1 to form the sheet 5, which is completely sealed.

This connection is achieved, for example, by providing an annular shape 12, by heat sealing, ultrasonic welding, bonding, etc., so that the connection of the two plate-like elements is stable.

Advantageously, the surface 1a of the magnetic body 1
Is a surface which can be coupled with another similar magnetic body or with a ferromagnetic body provided on another flap to be coupled, which is substantially flat. As a result, the formation of protruding edges in the interconnecting regions can be avoided. The sheet 5 is thus in fact formed in the lateral part by the plate-like element 11 for the special case.

Advantageously, the plate-like elements 10, 11 are P
Made of VC or other calendered synthetic resin material. And this solution is ideally suited for using magnetic closures for clothing items, or in any case, for elements that can be applied by heat sealing or ultrasonic welding.

If it is necessary to apply the closure by sewing, the use of a plate-like element made of calendered synthetic resin material is not advisable, since it is destroyed by sewing.

By means of sewing, in order to facilitate the application of the magnetic closure, one of the plate-like elements, preferably the plate-like element 10 which does not constitute an area for coupling with the other magnetic closure, must be waterproofed. Provided by the intended fabric coated with PVC, polyurethane, or other synthetic resin material.

The combination of the two plate-like elements produces wrinkles which reduce the friction and reduce the adhesive strength, so that the two plate-like elements 10, made of fabric covered with a synthetic resin material,
It is not wise to use 11. If the bonding surface is completely smooth, the adhesion will be optimized instead, as it really happens with a smooth calendered plastic part whose suction force can be freely adjusted by its thickness. I have.

Advantageously, a magnetic closure as described above is provided by using a strip of material indicated by reference numeral 20 in FIGS. The various magnets are already inserted at a preset distance and are easily connected to items of clothing, as shown schematically in FIGS.

From the above description, it is evident that the present invention has achieved the stated objects, and it is particularly emphasized that the following magnetic closures are provided. That is, the magnetic closure can be optimized for the optimal machine, even with the improvement that the bonding surface is substantially flat and the material of the other bonded plate-like element is actually used to form a sealed sheet. It enables the permanent magnet to be confined in a sealed area that provides the desired strength.

Furthermore, a magnetic closure is realized by providing a magnetic body with a magnet that is permanently associated with a plate-like element made of a ferromagnetic material that concentrates magnetic flux lines. The magnetic flux lines therein are substantially outwardly directed and emit less radiation at the rear of the item which can make constant contact with the user's body.

The invention thus devised can be subjected to various modifications, all of which are within the scope of the present invention.

Any details may be replaced by other technically equivalent elements.

In practice, as well as dimensions and shapes, the materials used can be any according to the requirements.
