Abstract:
1. A user height adjustable table comprising: a table top comprising a top surface and a bottom surface; a first and a second lockable height adjustable mechanism, wherein each lockable height adjustable mechanism comprises at least one height adjustment mechanism; wherein each height adjustment mechanism can move; wherein said table top is disposed above and is supported by each lockable height adjustable mechanism; at least one movable locking mechanism; wherein each movable locking mechanism is selectively movable from a first locked position to a second unlocked position; wherein when each movable locking mechanism is moved to said unlocked position, each height adjustment mechanism can move, wherein each lockable height adjustable mechanism is actuated; wherein said user height adjustable table comprises a floor contacting lower portion, and an upper portion supported by said floor contacting lower portion; wherein said upper portion can move upwardly and downwardly relative to said lower portion; wherein an upward or downward force applied to said upper portion can cause said table top to be moved relative to said floor contacting lower portion and the floor; wherein one said height adjustment mechanism comprises movable resilient spring material which can apply upward force to said upper portion; wherein upon actuation of said first and said second lockable height adjustable mechanisms, said resilient spring material can resiliently move resulting in moving said upper portion upwardly away from said floor contacting lower portion and the floor unless said upper portion supplies sufficient compressive force; wherein at least said table top comprises said upper portion; wherein said table top comprises a length and a depth; wherein said lockable height adjustable mechanisms are disposed in line with said length, orthogonal and parallel to said depth; an actuation mechanism supported on said user height adjustable table for moving each movable locking mechanism; wherein said actuation mechanism is disposed proximate said table top, and wherein when moved, said actuation mechanism can move each movable locking mechanism at least to said second unlocked position wherein each lockable height adjustable mechanism is actuated; a first pushing surface; a second pushing surface; a first pulling surface; a second pulling surface; wherein each of said first and said second pushing and pulling surfaces are disposed on said upper portion; wherein when said first and said second lockable height adjustable mechanisms are actuated, the hands of a table user can apply a downward force to said first and said second pushing surfaces wherein said upper portion can be moved downwardly toward said floor contacting lower portion wherein the height of said table top is adjusted relative to the floor, and wherein the hands of a table user can apply an upward force to said first and said second pulling surfaces wherein said upper portion can be moved upwardly away from said floor contacting lower portion wherein the height of said table top is adjusted relative to the floor; wherein said actuation mechanism is disposed proximate said first pushing surface and said first pulling surface; wherein a table user can contact and move said actuation mechanism with at least one hand, while simultaneously applying downward force to said first pushing surface with that same hand and downward force to said second pushing surface with user's other hand; wherein said table user can actuate said first and said second lockable height adjustable mechanisms with both hands positioned substantially above said table top while simultaneously applying downward force to said first and said second pushing surfaces; wherein the height of said table top can be adjusted downwardly toward said floor contacting lower portion and the floor; wherein a table user can contact and move said actuation mechanism with at least one hand, while simultaneously applying upward force to said first pulling surface with that same hand and upward force to said second pulling surface with user's other hand; wherein said table user can actuate said first and said second height adjustable mechanisms with both hands positioned substantially above said table top while simultaneously applying upward force to said first and said second pulling surfaces; wherein the height of said table top can be adjusted upwardly away from said floor contacting lower portion and the floor; wherein upon actuation of said first and said second lockable height adjustable mechanisms when said upper portion is moved upwardly away from said lower portion, a supply of sufficient downward compressive force by said upper portion can cause said upper portion to move downward toward said floor contacting lower portion and the floor; wherein said lockable height adjustable mechanism must be actuated to adjust the height of said table top relative to said floor contacting lower portion and the floor.
