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.

Claims

1. An umbrella frame comprising:

a post having a top end and a bottom end, the post consisting of a plurality of first wires, said first wires disposed adjacent and parallel to each other, the post further includes a plurality of first spacers between said first wires, said first wires and first spacers fixedly bound together at a plurality of locations along the length of the post and defining an empty space between said first wires;

a plurality of arms each arm having an inner end rotatably coupled to the post promote the top end and an outer end, each arm consisting of a plurality of second wires, said second wires of each arm disposed adjacent and parallel to each other, each of said arms further including a plurality of second spacers between said second wires of each arm, said second wires and second spacers of each arm fixedly bound together at a plurality of locations along the length of each arm definition an empty space between said second wires;

a movable lift ring circumferentially and slidably mounted to the post and moveable between a lower position and an upper position;

a number of module connector members equal in number to the number of arms, each module connector member having a first end and a second end, the first end of each module connector member rotatably connected to one of said plurality of arms at a fixed intermediate location along the arm, the second end of each module connector member rotatably connected to a position on the lift ring corresponding to the orientation of the corresponding one of said plurality of arms; and

a lock for removably securing the lift ring in the upper position whereby to prevent the lift ring from movement down the post;

said lift ring moveable from the lower closed position, where the umbrella arms are retracted along side the post, to the upper open position, whereby the umbrella arms are rotated upwardly with the outer ends of the arms spread apart and where said lift ring is moveable downward from the upper open positions back to the lower closed position.

2. The umbrella frame according the claim 1, wherein the first spacers and second spacers are located in-between the respective plurality of first wires and the second wires.

3. The umbrella frame according to claim 1, wherein the second wires of each arm are oriented in a vertical plane with respect to each other.

4. The umbrella frame according to claim 1, wherein the lift ring moves upwardly along the post causing the module connector member to move toward the post top causing the respective arms to rotate upwardly and outwardly thereby opening the arms and wherein the lift ring moves downwardly along the post causing the module connector member to move towards the post bottom causing the respective arms to rotate downwardly and inwardly thereby closing the arms.

5. The umbrella frame according to claim 1, further comprising a fabric cover affixed the arms of the frame.
