Document Type and Number:
WIPO Patent Application WO/2003/052298
Kind Code:
A1
Abstract:
A toggle joint pedal boosting mechanism, which is known as a high output mechanism used for a manual press and a metal shear, capable of developing a high drive force of a pedal by eliminating such a problem with a conventional manual drive device that an output provided by a depressing force on the pedal is physically powerless. A pedal device capable of providing a high output by installing a differential gear device in the body fixed part of the toggle joint mechanism and connecting a link device to a sliding part. Also a pedal device capable of developing a high output at the sliding end thereof by fixing a bell crank bent part to a body installing the differential gear part thereon, and towing a connection part between a bell crank short side and a toggle joint by a towing link, wherein a high output and a high capacity are provided in the developing configuration of a bicycle and a man power flight which was considered impossible before is allowed. A water moving device formed by connecting an articulated link extendable mechanism having a potential boost structure, i.e., a pantograph to the pedal mechanism and drivingly towing a paddling device.
