Umbrella assembly and umbrella stability assembly

Abstract

An umbrella assembly including a central shaft, the central shaft having a first end and a second end opposite the first end; a canopy coupled to the first end of the central shaft; an auger extending from the second end of the central shaft; a collar/hub nonslideably coupled to the central shaft and spaced from the auger; a plurality of legs, each of the plurality of legs having a first end and a second end; wherein the first end of each of the plurality of legs is coupled to the collar/hub, the second end of each of the plurality of legs extends towards the auger, and the collar/hub remains in a fixed position with respect to the central shaft when the second end of each leg extends outwardly from the central shaft to a deployed position and returns towards the central shaft from its deployed position to a stowed position; and a flexible material having an opening through which the central shaft extends and wherein the second end of each leg is coupled to the flexible material.

1 . A lower assembly of an umbrella assembly, the lower assembly comprising:
 a central shaft, the central shaft having a first end and a second end opposite the first end;   an auger extending from the second end of the central shaft;   a collar/hub nonslideably coupled to the central shaft and spaced from the auger;   a plurality of legs, each of the plurality of legs having a first end and a second end;   wherein the first end of each of the plurality of legs is coupled to the collar/hub, the second end of each of the plurality of legs extends towards the auger, and the collar/hub remains in a fixed position with respect to the central shaft when the second end of each leg extends outwardly from the central shaft to a deployed position and returns downwardly towards the central shaft from its deployed position to a stowed position; and   a flexible material having an opening through which the central shaft extends and wherein the second end of each leg is coupled to the flexible material.   
     
     
         2 . The lower assembly as claimed in  claim 1 , wherein when the second ends of the respective legs are in each of their respective deployed positions and the flexible material in an open position, the flexible material is intermediate the auger and the collar/hub. 
     
     
         3 . (canceled) 
     
     
         4 . (canceled) 
     
     
         5 . The lower assembly as claimed in  claim 1 , wherein the collar/hub comprises a plurality of leg receptacles extending from the collar/hub, each of the plurality of leg receptables being associated with one of the legs of the plurality of legs;
 wherein each leg receptacle includes a pin extending therethrough upon which the leg associated with the leg receptacle is coupled so as to permit the associated leg to be extended outwardly and returned towards the shaft.   
     
     
         6 . The lower assembly as claimed in  claim 1 , wherein (i) extension of the plurality of legs outwardly from the central shaft to their respective deployed positions extends the flexible material to an open position; and (ii) returning of the plurality of legs towards the central shaft to their respective stowed positions causes the flexible material to return to a collapsed position. 
     
     
         7 . (canceled) 
     
     
         8 . The lower assembly as claimed in  claim 1 , wherein the second end of each leg is coupled to the flexible material about the perimeter of the flexible material. 
     
     
         9 . The lower assembly as claimed in  claim 1 , wherein the flexible material includes one or more sidewalls to facilitate retention of material on the flexible material within an area bounded by the sidewall(s). 
     
     
         10 . The lower assembly as claimed in  claim 9 , wherein the one or more sidewalls extend along the entire perimeter of the flexible material. 
     
     
         11 - 18 . (canceled)
