The frame includes a post and top piece, a number of arms, a number of connectors, a lift ring and a locking pin. The post includes a number of rod members attached together in adjacent parallel space orientation with a top piece which rotatably attaches to each of a number of arms each arm having a number of arm rod members attached together in adjacent parallel space orientation. Each arm is rotatably attached to one end of a connector. The other end of each connector is rotatably attached to the lift ring. Raising and lowering the lift ring opens and closes the umbrella arms. The locking pin holds the lift ring in an upper position. ## Claims ### Claim 1 An umbrella frame, comprising: a center post comprising a plurality of parallel post rods spaced apart from one another by a plurality of post rod spacers distributed along the length of the center post; a plurality of arms extending outwardly from a top end of the center post, each arm being connected to the center post by a first rotatable connection member; a lift ring mounted circumferentially to the center post and being moveable up and down the center post; and a plurality of connector arms, each connector arm having a first end connected to the lift ring and a second end connected to a fixed intermediate location along one of the arms, each connector arm being connected to the lift ring by a second rotatable connection member, and each connector arm being connected to the fixed intermediate location along one of the arms by a third rotatable connection member; at least one of the first, second or third rotatable connection members comprise: a first disk with a central opening, a second disk with a central opening, and an axial member passing through the central openings of the first and second disks permitting the first and second disks to rotate with respect to one another. ### Claim 2 (depends on 1) The umbrella frame of claim 1, wherein at least one of the first, second and third rotatable connection members further comprises a low friction disk with a central opening, the low friction disk being positioned between the first and second disks with the axial member passing therethrough to reduce friction caused by rotation of the first disk with respect to the second disk. ### Claim 3 (depends on 1) The umbrella frame of claim 1, wherein the axial member is a pop rivet. ### Claim 4 (depends on 1) The umbrella frame of claim 1, further comprising: a base for supporting the center post. ### Claim 5 (depends on 1) The umbrella frame of claim 1, further comprising: an extension member for supporting the center post. ### Claim 6 (depends on 5) The umbrella frame of claim 5, further comprising: a base for supporting the extension member. ### Claim 7 (depends on 1) The umbrella frame of claim 1, wherein each of the plurality of arms comprise a plurality of parallel arm rods spaced apart from one another by a plurality of arm spacers distributed along the length of the arm. ### Claim 8 (depends on 1) The umbrella frame of claim 1, wherein each of the plurality of connector arms comprise a plurality of parallel connector arms spaced apart from one another by a plurality of connector arm spacers distributed along the length of the connector arm. ### Claim 9 (depends on 1) The umbrella frame of claim 1, wherein the lift ring comprises an upper lift ring and a lower lift ring spaced apart by a plurality of vertical ring spacers. ### Claim 10 (depends on 1) The umbrella frame of claim 1, further comprising: a canopy mounted onto the plurality of arms. ### Claim 11 An umbrella frame, comprising: a center post; a plurality of arms extending outwardly from a top end of the center post, each arm being connected to the center post by a first rotatable connection member, wherein each of the plurality of arms comprise a plurality of parallel arm rods spaced apart from one another by a plurality of connector arm spacers distributed along the length of the arm; a lift ring mounted circumferentially to the center post and being moveable up and down the center post; and a plurality of connector arms, each connector arm having a first end connected to the lift ring and a second end connected to a fixed intermediate location along one of the arms, each connector arm being connected to the lift ring by a second rotatable connection member, and each connector arm being connected to the fixed intermediate location along one of the arms by a third rotatable connection member; at least one of the first, second or third rotatable connection members comprise: a first disk with a central opening, a second disk with a central opening, and an axial member passing through the central openings of the first and second disks permitting the first and second disks to rotate with respect to one another. ### Claim 12 (depends on 11) The umbrella frame of claim 11, wherein at least one of the first, second and third rotatable connection members further comprises a low friction disk with a central opening, the low friction disk being positioned between the first and second disks with the axial member passing therethrough to reduce friction caused by rotation of the first disk with respect to the second disk. ### Claim 13 (depends on 11) The umbrella frame of claim 11, further comprising: an extension member for supporting the center post. ### Claim 14 (depends on 13) The umbrella frame of claim 13, further comprising: a base supporting the extension member. ### Claim 15 (depends on 11) The umbrella frame of claim 11, further comprising: a base for supporting the center post. ### Claim 16 (depends on 11) The umbrella frame of claim 11, wherein the lift ring comprises an upper lift ring and a lower lift ring spaced apart by a plurality of vertical ring spacers. ### Claim 17 (depends on 11) The umbrella frame of claim 11, further comprising: a canopy mounted onto the plurality of arms. ### Claim 18 An umbrella frame, comprising: a center post comprising a plurality of parallel post rods spaced apart from one another by a plurality of post rod spacers distributed along the length of the center post; a plurality of arms extending outwardly from a top end of the center post, each arm being connected to the center post by a first rotatable connection member, wherein each of the plurality of arms comprise a plurality of parallel arm rods spaced apart from one another by a plurality of connector arm spacers distributed along the length of the arm; a lift ring mounted circumferentially to the center post and being moveable up and down the center post; and a plurality of connector arms, each connector arm having a first end connected to the lift ring and a second end connected to a fixed intermediate location along one of the arms, each connector arm being connected to the lift ring by a second rotatable connection member, and each connector arm being connected to the fixed intermediate location along one of the arms by a third rotatable connection member; wherein at least one of the first, second or third rotatable connection members comprise: a first disk with a central opening, a second disk with a central opening, and an axial member passing through the central openings of the first and second disks permitting the first and second disks to rotate with respect to one another. ### Claim 19 (depends on 18) The umbrella frame of claim 18, wherein at least one of the first, second and third rotatable connection members further comprises a low friction disk with a central opening, the low friction disk being positioned between the first and second disks with the axial member passing therethrough to reduce friction caused by rotation of the first disk with respect to the second disk.
