Button opening and closing apparatus

The present invention is an improvement technique of the applicant's prior application 20-1996-0038089 (filed Nov. 01, 1996) (Registration No. 0159366).

The present invention relates to a portable bag and a button for clothes and all the opening and closing device of the related products, and more particularly, it is possible to use semi-permanently by improving the durability by ensuring the stability of the repeated operation repeatedly.

The present invention has the data that can be used more than 23,000 times in the test report of the accredited laboratory for the durability tensile strength test is a product of the customer's trust.

Generally, various means for fixing the door part of a bag or a handbag from a main body are used. Among these means, the method of opening and closing using a jacket, opening and closing with synthetic adhesive material (adhesive velcro tape) to stick both sides together, and applying and opening passwords to a rectangular bag containing important documents And many other methods are applied.

In addition to the above method, as a method mainly used in women's handbags, a fixing method using a magnetic force in which a protrusion installed in a door part contacts a magnet recess of a portable bag body by magnetic force has recently been widely used. This has the advantage that the configuration of the portable bag can be properly fixed to the main body without being complicated and simple.

However, the fixing method using the magnet is fixed to the main body of the portable bag by the magnetic force of the magnetic recess of the portable bag, there is a limit in the magnetic strength of the magnet is fixed in the body unintentionally when storing a large amount of goods in the handbag If the self-locking force of the door part is not able to withstand the force of the stored article forcibly, there is a problem that the door part is opened and the items stored therein are poured out.

In addition, inside the portable bag, which is often used by women, most of them store and use various cards including wallets, credit cards, phone cards, and cash cards in the wallet. Since it is located on the back, the cards are often not used due to accidental contact with the magnet recesses fixed to the main body. There was a drawback of having to consistently accept the inconvenience, and these magnets were mainly product-dependently used for imports, and the cost of imports was high.

In the case of the earlier application 20-1996-0038089 (filed Nov. 01, 1996) (Registration No. 0159366), the fitting plate was fixed to the door part by inserting and bending the fixing protrusion of the fitting plate to the fitting hole. There is a problem that the bent projections are loosened or released from the door part by returning to the original state as the opening and closing operation is repeated.

In addition, the biggest problem of the currently released button is the spring button of the women's wallet which is used most in addition to the applicant's product, and the various pins have been removed from the manufacturer or dealer because of the fixing pins that fixed the main body (fabric) to the fitting plate. Or, a / s request is frequent, a large number of a / s team should be kept separately, wasting a lot of manpower, and in the case of the main body, the structure that couples and fixes the lower stationary body to the main body may have the same problem. As well as. There was also a problem that the combined separation operation (opening / closing operation) of the fitting protrusion of the fitting plate fixedly coupled to the door part and the elastic fixing member coupled to the main body was impossible to be made perfectly.

The present invention was made to solve the above problems, by changing the coupling structure of the fixing pin for fixing the insertion hole and the fabric which was the biggest problem, the self-fixed so as not to be detached and fitted with a tapered washer made of a multi-angle As the tapered surface of the ball is supported in a precise size, it is not permanently detached, and it improves the convenience and productivity of manufacturing clothes or handbags.
