Abstract:
A self-tilting connector mechanism of an umbrella comprising:(a) a seat having a hollow tubular body and a bottom section thereof being a tube section with a through hole, a top end thereof being a locking hole and a sectional slot; (b) a tilting head seat mounted within the body, an interior of an upper section of the tilting head seat being moveably locked with a pulley, and a bottom section thereof being mounted with two protruded plates forming an open slot therebetween, the two protruded plates being provided with a positioning hole and a combining hole; (c) a steel cable having one end mounted to an umbrella runner and having the other end mounted to a rotating shaft of a handle and being wound around a positioning pulley located at an upper section of the umbrella runner, the pulley on the tilting head seat and the driving pulley of a pulling shaft; (d) a linking shaft having an elongated body and having a bottom end and a top end each provided with a hole, a lower section of the hole of the top end being mounted with a spring and a positioning button; (e) a pulling shaft having a sectional slot at an upper section thereof, and an interior of the sectional slot being provided with two locking holes for moveably mounting a driving pulley and the linking shaft, the end terminal of the bottom section of the pulling shaft being mounted with a spring such that the spring urges a tubular section of the seat, a lower section of the spring being transversely mounted with a locking pin to prevent dislocation of the spring; wherein a lower section of the linking shaft has an engaging slot having a spring and the positioning button having a sliding slot, and the linking shaft is provided with a positioning slot, and a locking body is inserted into the positioning slot of the linking shaft and the positioning button for securing; if the handle is rotated clockwise, the steel cable will be wounded to drive, and the top end of the steel cable is a fixed point., and through the driving pulley and the pulley mechanism of the pulley, the pulling shaft is driven upward, and the tilting head seat is restricted by the pegging of the peg, and thus the linking rod is rotated to push the protruded plate of the tilting head seat to go outwardly, and the recessed arch will tilt downward, and the linking rod moves upward to compress the spring connected to the bottom end of the tilting head seat and at the same time the positioning button is released from the fastening position of the seat, and the linking shaft inclines at the swing head with an appropriate angle; whereby the linking shaft locks at the combining hole of the bottom section of the two protruded plates of the tilting head seat and locks at the sectional slot of the pulling shaft such that the pulling shaft is mounted at the hole of the tubular section of the bottom section of the seat, and by means of winding of a steel cable, rotating adjustment of the handle can achieve opening, tilting and reverse tilting, and closing of the umbrella.
