Umbrella stand adaptable for support on a table

Abstract

An umbrella stand includes a base plate positionable on a table. A tube is connected to the base plate and includes an opening formed therein sized to receive a portion of the umbrella pole. A shaft is connectable to the base plate in opposed relation to the tube. A bottom cap is threadedly engageable with the elongate shaft. First and second strap assemblies are coupled to the base plate, with each including a strap and a clamp coupled. The umbrella stand is useable in a first mode wherein the shaft is connected to the base plate, and the bottom cap is connected to the elongate shaft, and the clamps are disengaged from the peripheral edge of the table. The umbrella stand is useable in a second mode, wherein the shaft is disconnected from the base plate, and the clamps are engaged to the peripheral edge of the table.

         2 . The umbrella stand recited in  claim 1 , wherein a position of the bottom cap is selectively adjustable along the elongate shaft via rotation of the bottom cap relative to the elongate shaft. 
     
     
         3 . The umbrella stand recited in  claim 1 , further comprising a first magnet connected to the first table edge clamp and a second magnet connected to the second table edge clamp, the first and second magnets being configured to facilitate selective magnetic coupling of the first and second table edge clamps, respectively, to the tube. 
     
     
         4 . The umbrella stand recited in  claim 1 , further comprising a first spring in operative communication with the first strap to impart a tensioning force on the first strap. 
     
     
         5 . The umbrella stand recited in  claim 1 , further comprising:
 a third strap assembly coupled to the base plate and including a third strap and a third table edge clamp coupled to the third strap; and   a fourth strap assembly coupled to the base plate in opposed relation to the third strap assembly and including a fourth strap and a fourth table edge clamp coupled to the fourth strap;   wherein the first and second strap assembles reside on a first common axis, and the third and fourth strap assembles reside on a second common axis which is offset approximately ninety degrees from the first common axis.   
     
     
         6 . The umbrella stand recited in  claim 1 , wherein the base plate defines an outer diameter between 4-30 inches. 
     
     
         7 . The umbrella stand recited in  claim 1 , wherein the elongate shaft is threadably engageable to the base plate. 
     
     
         8 . The umbrella stand recited in  claim 7 , further comprising an externally threaded connector mounted on the elongate shaft and configured to engage with an internally threaded opening on the base plate. 
     
     
         9 . The umbrella stand recited in  claim 8 , further comprising a plate connected to the tube and extending within the opening of the tube, the plate having an opening formed therein and alignable with the externally threaded connector when the externally threaded connected is engaged with the base plate. 
     
     
         10 . The umbrella stand recited in  claim 1 , wherein the first table edge clamp includes a first clamping plate and a second clamping plate moveable relative to the first clamping plate. 
     
     
         11 . The umbrella stand recited in  claim 10 , wherein the first table edge clamp includes an inner corner bracket and an outer corner bracket, the first clamping plate being on the inner corner bracket and the second clamping plate being on the outer corner bracket. 
     
     
         12 . The umbrella stand recited in  claim 10 , further comprising a pad connected to the first clamping plate. 
     
     
         13 . An umbrella stand for use with an umbrella pole and a table having an upper surface and a peripheral edge, the umbrella stand comprising:
 a base plate positionable on the upper surface of the table;   a tube connected to the base plate and having an opening formed therein sized to receive a portion of the umbrella pole;   a first strap assembly coupled to the base plate and including a first strap and a first table edge clamp coupled to the first strap; and   a second strap assembly coupled to the base plate in opposed relation to the first strap assembly and including a second strap and a second table edge clamp coupled to the second strap;   the umbrella stand being useable in a first mode, wherein the first and second strap assemblies are positioned with the first and second table edge clamps being disengaged from the peripheral edge of the table;   the umbrella stand being useable in a second mode separate from the first mode, wherein the first and second strap assemblies are positioned with the first and second table edge clamps being engaged from the peripheral edge of the table.   
     
     
         14 . The umbrella stand recited in  claim 13 , further comprising
 a shaft connectable to the base plate so as to extend from the base plate in opposed relation to the tube; and   a bottom flange connectable to the shaft and configured to be moveable along the shaft when connected thereto;   the shaft being connected to the base plate, and the bottom flange being connected to the shaft when the umbrella stand is used in the first mode;   the shaft being disconnected from the base plate when the umbrella stand is used in the second mode.   
     
     
         15 . The umbrella stand recited in  claim 14 , wherein the bottom flange is rotatably connectable to the shaft.
