Abstract
An umbrella frame has a post, a number of arms, a number of connecting rods, a lift ring and a ring lock. The post has a number of aligned wire elements connected to each other along their length with a number of post spacers. Each arm has at least two aligned wire elements connected together along their length with a number of arm spacers. Each arm is connected to the top of the post and rotates upward from a closed position along the post to an upward open position and back. The lift ring slides up and down the post to open and close the umbrella frame. Each connection rod is connected to the lift ring at one end and the other end to a mid-point on each respective arm. The ring lock secures the lift ring to the post in the open position.
