Title:
CHAIN CONNECTING METAL FITTING ATTACHABLE BY LIGHT FORCE AND CONNECTING MECHANISM
Document Type and Number:
Japanese Patent JP2009292300
Kind Code:
A
Abstract:

To simplify connecting work of a chain by reducing a force required when attaching a chain connecting metal fitting by changing the shape of the chain connecting metal fitting in a simple S-shape without no conspicuous improvements, and to cope with a problem wherein even the chain connecting metal fitting having no finger hook is sufficient as a structure to attain connecting of the chain, but actually attaching work by a hand of a person is not much considered.

The force required for attaching the chain connecting metal fitting is reduced by providing the chain connecting metal fitting with the finger hook at a position far from a rotary shaft, to which force is easily applied by a principle of a lever. Parts except the chain connecting metal fitting are the same as the chain connecting metal fitting having no finger hook, and thereby the parts except the chain connecting metal fitting, which are the same as a chain connecting mechanism using the chain connecting metal fitting having no finger hook, can be used as they are.
