wherein the runner comprises a locking mechanism to keep the umbrella open or closed when the runner is pushed up or pulled down. ### Claim 4 (depends on 3) The umbrella with heater according to claim 3 wherein the locking mechanism is a locking shaft ring. ### Claim 5 (depends on 3) The umbrella with heater according to claim 3 wherein the shaft comprises a hollow interior such that the heating subsystem and the air moving subsystem are housed within the shaft; wherein the hollow interior provides a pathway for the warm air to travel to the top of the umbrella and then out to the plurality of ribs. ### Claim 6 (depends on 5) The umbrella with heater according to claim 5 wherein the handle is the bottom of the shaft; wherein the handle is adapted to be held by the user; wherein the handle comprises a contoured grip. ### Claim 7 (depends on 6) The umbrella with heater according to claim 6 wherein the plurality of stretchers are armatures that support the plurality of ribs; wherein the bottoms of the plurality of stretchers pivotably couple to the runner; wherein the tops of the plurality of stretchers pivotably couple to the plurality of ribs; wherein an individual stretcher couples to an individual rib in a one-to-one correspondence. ### Claim 8 (depends on 7) The umbrella with heater according to claim 7 wherein the plurality of ribs are coupled to the underside of the canopy and shape the canopy; wherein the proximal end of the plurality of ribs pivotably couple to the top hub; wherein when the umbrella is in the closed configuration, the plurality of ribs are oriented parallel to the shaft and pull the canopy in towards the shaft; wherein when the umbrella is in the deployed configuration, the plurality of ribs are oriented perpendicular to the shaft and stretch the canopy into a dome shape; wherein the plurality of ribs are hollow such that the warm air passes through the plurality of ribs; wherein the plurality of air outlet apertures are dispersed along the individual rib on the underside of the individual rib, away from the canopy. ### Claim 9 (depends on 8) The umbrella with heater according to claim 8 wherein the top hub comprises a top hub plenum;
