Claim 1
Independent Claim 297 words
A portable outdoor chair, having a seat portion, which seat portion is capable of being semi-automatically rotated in a horizontal plane about a base member, said device comprising: (a) a base member with vertically depending legs for fixedly positioning said base member on the ground, said base member having a horizontally disposed plate member disposed on the upper surface of said base member, said plate member comprising on its peripheral surface a ring gear member with female openings on the circumference thereof to receive male gear teeth; (b) an upper pivotable member pivotally mounted to the lower base member, said upper pivotable member having seat means integrally affixed to the upper portion of said upper pivotable member; (c) combined ratchet and movement means integrally disposed on said upper pivotable member about said base member in a pivotable manner, said combined movement and ratchet means comprising a longitudinal shaft member, said shaft member being housed in a cylindrical housing and wherein said shaft has an upper end and a lower end, wherein said upper end has a circular head concentrically mounted on said end, and on the upper surface of said circular head is mounted a plurality of bosses and a pivotable handle, one end of which is engageable with one or more such bosses when said handle is pivoted downwardly, whereas said handle when engaged against one or more such bosses will cause said shaft to rotate, and wherein mounted concentrically on the lower end of said shaft is a circular follower gear adapted to movingly engage the ring gear on said base member such that rotation of the shaft by said handle will cause said shaft to rotate said follower gear about said ring gear causing the upper pivotable member to pivot about said base member.
