Abstract:

To provide a hook tool which prevents biasing means from protruding even if a load larger than predicted is input.SOLUTION: A hook tool includes a curve part and an opening/closing bar. The curved part comprises a shoulder part and a lower curved part. The opening/closing bar is a bar which is detachably attached to the shoulder part. The curved part and the opening/closing bar are rotatably coupled by a curved part rotation section and an opening/closing bar rotation section. The curved part rotation section includes protruding parts at both sides and upper semicircular protruding parts. The opening/closing bar rotation section includes circular disc sandwiching parts at both sides. The sandwiching parts are rotatably fitted with the protruding parts through holes. An opening/closing bar lower end part is biased in a direction of an opening end part by biasing means at the protruding part. When the opening/closing bar is engaged with the shoulder part against the biasing means, a belt-like protrusion and a groove are engaged and protrusions of the shoulder part and opening/closing bar engagement recessed parts are engaged to open the hook tool. When the opening/closing bar is biased by the biasing means, the hook tool is closed by engagement of the lower end part and the opening end part. The hook tool includes a spring-up prevention protrusion which engages with the upper semicircular protruding part of the sandwiching part to prevent spring-up of the opening/closing bar when the lower end part and the opening end part are open and the opening/closing bar is sprung up.SELECTED DRAWING: Figure 1
