Abstract
A folding umbrella frame is provided which includes an improved frame linkage having a second stick with a recess formed within it and an inclined outer end pivotally secured to a fourth rib member. A first stick member is coupled to a first rib member and includes a second end which is inclined and is pivotally secured to a third rib member. The first rib member has an end which is inclined for pivotal coupling to a central section of a second rib member. The inclined ends of the first rib member, the first stick member and the second stick member reduces the force required to open and close the folding umbrella while the recess receives an end of the first rib member to reduce the volume of the umbrella when in a closed state.
