Abstract

PROBLEM TO BE SOLVED: To provide a hook device excellent in operability and not damaging the fabric of clothes by forming at least one of two hook members with a permanent magnet, forming the other with a ferromagnetic substance or a permanent magnet, and applying magnetic force between both hook members directly or via the clothes to connect both hook members. SOLUTION: The first hook member is constituted of a permanent magnet 3, a casing 4, and an ornament 5, and the second hook member is constituted of a ferromagnetic substance 6 made of a soft steel sheet and a casing 7. The ferromagnetic substance 6 of the second hook member 2 is made larger in size than the permanent magnet 3 so that magnetic force is easily applied when the first hook member 1 is moved nearby within some range. A material having a high saturation magnetization characteristic such as a rare earth magnet is advantageous for the permanent magnet 3 because a necktie and a shirt exist between the first hook member 1 and the second hook member 2 to provide some distance. A necktie hook has the same decorative design like a necktie tack with a pin piercing the necktie and shirt, and it does not damage the necktie.
