Problems solved by technology

However, the conventional low-profile design often results in insufficient magnetic bonding force between magnetic pairs. Therefore, so far, it is still inevitable to use complex additional joint devices for this low-profile structure.

Embodiment Construction

[0059] First refer to figure 1 Turning to FIG. 3, a magnetic element 10 and a housing 20 are shown. When the magnetic elements 10 and 20 are assembled together, the magnetic clasp according to the first preferred embodiment of the present invention is formed. Magnetic element 10 is the source of magnetic engagement force for engagement with a mating magnetic clasp. Preferably, this magnetic element comprises a permanent magnet in the form of a magnetic piece and is made of a strong magnetic substance or alloy to provide a high magnetic force to volume ratio so that the clasp The structure is very compact. Using current magnetic technology, a pair of complementary magnetic pieces with a diameter of 1 cm and a thickness of about 1 mm, and with the appropriate configuration described herein, can generate magnetic engagement forces as high as 20-30N.

[0060] In this preferred embodiment, the magnetic sheet is substantially circular or cylindrical, with a diameter of about 12 mm...

Abstract

Magnetic fastener pairs with low-profile designs which allow strong magnetic coupling between the constituting magnetic fastening members while also permitting easy intentional separation. Each of the magnetic fasteners includes a magnet receptacle and a permanent magnet made preferably of a strong magnetic alloy. Each magnet member is backed by a ferro-magnetic base of the magnet receptacle of the fastener member and with an exposed coupling surface for strong magnetic coupling while allowing easy intentional separation.

Description

technical field [0001] The present invention relates generally to fasteners, and more particularly to magnetic fasteners, such as magnetic clasps and rings, magnetic strap fasteners or belt fasteners. More particularly, although not limited thereto, the invention also relates to fasteners, such as buttons or buckles, for garments such as brassieres. The invention also relates to garments with magnetic fasteners. Background technique [0002] In a traditional fastener assembly, such as a row of buttons, the button is fastened or unfastened by inserting the button into the buttonhole or unfastening the button from the buttonhole. Magnetic buttons and magnetic fasteners are different from this traditional Different from other fasteners, magnetic buttons and magnetic fasteners are fastened or fixed by the mutual magnetic attraction between a pair of complementary magnetic fasteners or magnetic buttons with complementary or opposite magnetism. This characteristic of magnetic fa...
