摘要： A folding chair having at least one offset pyramid hinge, two chair legs, a chair-backing, and a seating member which can fold substantially flat in a closed position, and can substantially lock open in an opened position. The offset hinge of the chair promotes the chair remaining in either a flattened or open position by positioning the intersecting junctions at apices which are offset from one another.

摘要： Phase gear and lever mechanism converts reciprocating power to rotary power with phase gear providing power stroke of greater duration than travel stroke so as to develop efficient power through a power stroke. A modified lever and gear mechanism converts reciprocating power to rotary power at variable out power ratio. Both converting mechanisms are applied as bicycle drive mechanisms. Both mechanisms are applied together in a bicycle one as a drive mechanism, the other for synchronizing the drive mechanism.
