Cup holder adjustment system

Abstract

A cup holder adjustment system is provided, which can be placed in the arm of a folding chair. The cup holder adjustment system preferably includes two forms of adjustment. The first form of adjustment includes a. cord locking mechanism for raising and lowering the base of the cup holder on which the beverage vessel is seated. The depth of the cup holder is adjustable to account for the height of the beverage vessel. The second form of adjustment includes various flexible tab members that project inwardly within the cup holder to hold a beverage vessel in place. The tab members preferably include an inward biasing force causing the tab members to spring inwardly and flex downwardly. This tensioning force pushes the beverage vessel inwardly to help keep the beverage vessel in place when it is retained, within the cup holder.

1 . A cup holder adjustment system, comprising:
 a cup holder in which a drinking vessel may be secured;   one or more cord members coupled to the cup holder; and   a cord locking mechanism configured to adjust a depth of the cup holder via the one or more cord members.   
     
     
         2 . The cup holder adjustment system of  claim 1 , wherein each of the one or more cord members extend vertically along a walled portion of the cup holder. 
     
     
         3 . The cup holder adjustment system of  claim 1 , wherein the cord locking mechanism is configured to contain a portion of each of the one or more cord members. 
     
     
         4 . The cup holder adjustment system of  claim 1 , wherein the cord locking mechanism is configured to move in a vertical direction about the one or more cord members. 
     
     
         5 . The cup holder adjustment system of  claim 1 , wherein when the cord locking mechanism is moved in an upward direction, the depth of the cup holder is decreased. 
     
     
         6 . The cup holder adjustment system of  claim 1 , wherein when the cord locking mechanism is moved in a downward direction, the depth of the cup holder is increased. 
     
     
         7 . The cup holder adjustment system of  claim 1 , further comprising one or more tab members. 
     
     
         8 . The cup holder adjustment system of  claim 7 , wherein the one or more tab members are configured to extend inwardly and downwardly into the cup holder. 
     
     
         9 . A cup holder adjustment system, comprising:
 a cup holder;   a plurality of cord members configured to adjust a depth of the cup holder; and   a plurality of tab members projecting inwardly from the cup holder.   
     
     
         10 . The cup holder adjustment system of  claim 9 , wherein each of the plurality of cord members extend vertically along a walled portion of the cup holder. 
     
     
         11 . The cup holder adjustment system of  claim 9 , wherein a cord locking mechanism is configured to releasably secure a depth of the cup holder via the plurality of cord members. 
     
     
         12 . The cup holder adjustment system of  claim 11 , wherein the cord locking mechanism is configured to contain a portion of each of the plurality of cord members. 
     
     
         13 . The cup holder adjustment system of  claim 11 , wherein the cord locking mechanism is configured to move in a vertical direction about the plurality of cord members. 
     
     
         14 . The cup holder adjustment system of  claim 11 , wherein when the cord locking mechanism is moved in an upward direction, a depth of the cup holder is decreased. 
     
     
         15 . The cup holder adjustment system of  claim 11 , wherein when the cord locking mechanism is moved in a downward direction, a depth of the cup holder is increased. 
     
     
         16 . The cup holder adjustment system of  claim 9 , wherein the plurality of tab members flex downwardly depending on a diameter of a vessel contained in the cup holder. 
     
     
         17 . A cup holder adjustment system, comprising:
 a cup holder;   a cord locking mechanism; and   a plurality of tab members projecting inwardly from the cup holder;   wherein:
 when the cord locking mechanism is in a first position, the cup holder has a first depth; 
 when the cord locking mechanism is in a second position, the cup holder has a second depth; and 
 the second depth is less than the first depth. 
   
     
     
         18 . The cup holder adjustment system of  claim 17 , wherein when the cord locking mechanism is moved in an upward direction about a plurality of cord members, a depth of the cup holder is decreased. 
     
     
         19 . The cup holder adjustment system of  claim 17 , wherein when the cord locking mechanism is moved in a downward direction about a plurality of cord members, a depth of the cup holder is increased. 
     
     
         20 . The cup holder adjustment system of  claim 17 , wherein the plurality of tab members flex downwardly depending on a diameter of a vessel contained in the cup holder.
