Abstract

PURPOSE:To prevent unevenness or creases from appearing on the ornamental surface of an ornamental button by a method wherein the inside of the hollow section facing the hole of an ornamental buton is covered with a hard metal plate in a structure where the cylindrical fastening member of a connection fixture utilizing a permanent magnet and the ornamental button are fastened on cloth. CONSTITUTION:In a female connection fixture A, ferromagnetic member 2 is fixed on the magnetic pole face a of a permanent magnet 1 having a hole 1a extending from the one magnetic pole face a to the other magnetic pole face b. In a male connection fixture B, the ferromagnetic member 3 is detachably attracted to the connection fixture A through the hole 1a contacting the magnetic face b. The back of the members 2 and 3 is provided with a projecting, cylindrical fastening member 5. The member 5 is inserted into an attaching hole 6a on cloth 6, and a hollow section 8 is formed at the same time. The projecting end 5a of the member 5 is inlaied in an ornamental button 7 on whose backside, a hole 9 passing to the hollow section 8 is provided, and the end 5a is crimped. The inside of the hollow section 8 is covered with a metal plate 10, with the result that unevenness or creases are prevented from appearing on the ornamental plane of an ornamental button when the connection fixture is fastened on the cloth.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Applications n) The present invention utilizes a cylindrical engaging tool that uses a permanent magnet to attach to clothing, bag fabrics, etc. by using an L attachment member and a separately prepared decorative button. This invention relates to a fastening structure that prevents wrinkles that are likely to occur on the surface of a decorative button.

(Prior art) There are various structures for attaching an engaging tool using a permanent magnet to the fabric of a bag, etc., but especially when the attached part is exposed on the surface or in the case of clothing etc., there are various structures. In order to prevent damage and further improve the quality, fastening structures using decorative buttons are often used.

This includes a cylindrical fastening member protruding from the engaging tool, the fastening member being inserted into a mounting hole of the fabric, etc. to which the engaging tool is attached, and having a separately prepared hollow part. In addition, the protruding end of the fastening member is inserted into the decorative button, which has a hole on the back side that communicates with the hollow part, through the hole on the back side and is swaged within the hollow part, thereby fastening the button. Since the end of the member is inside the decorative button, it has a good appearance.

(Problems to be Solved by the Invention) However, since the tip of the cylindrical fastening member is inserted into the decorative button and caulked in the hollow part of the decorative button, unevenness and wrinkles occur on the decorative surface of the decorative button. However, there was a problem in that it spoiled the beautiful cosmetic surface.

(Means for Solving the Problems) The present invention solves the above-mentioned problems, and aims to fix the engaging tool without damaging the decorative surface of the decorative button. A ferromagnetic member 2 attached to the magnetic pole face a of a permanent magnet 1 having a hole 1a toward the magnetic pole face and a ferromagnetic member 3 abutting the magnetic pole face are connected through the hole 1a of the permanent magnet l. A cylindrical fastening member 5 is protruded from the back side of the attracting surface of both or one of the ferromagnetic members 2 and 3 in the engaging tool, which is detachably attracted to the ferromagnetic members 2 and 3. The attachment member 5 is inserted through the attachment hole 6a of the cloth 6 or the like to which the engagement tool is attached, has a separately prepared hollow section 8, and a hole 9 communicating with the hollow section 8 is provided on the back surface 7b. In the fastening structure of the engagement tool in which the protruding end portion 5a of the fastening member 5 is fitted into the decorative button 7 and is fastened by caulking within the hollow portion 8, the hole of the decorative button 7 is The inner surface of the hollow portion 8 facing the hard metal plate 10
