1. A workbench comprising:
- a work support structure;
a first leg member pivotable between a first position where said first leg member is folded against said work support structure and a second position where said first leg member extends downwardly from and supports said work support structure;
a second leg member pivotable between a first position where said second leg member is folded against said work support structure and a second position where said second leg member extends downwardly from and supports said work support structure;
a handle; and
a rack and pinion system coupling the first leg member, the second leg member, and the handle;
wherein moving the handle relative to the work support structure drives both the first leg member and the second leg member to pivot between the first position and the second position via movement in the rack and pinion system.

Abstract
A workbench includes a work support structure, a first leg member, a second leg member, a handle; and a rack and pinion system coupling the first leg, the second leg, and the handle. Moving the handle relative to the work support structure causes both the first leg member and the second leg member to extend from or retract into the work support structure via movement in the rack and pinion system.

5. A workbench comprising:
-
a work support structure having two side surfaces and two end surfaces; a first pair of slots, each slot of said first pair formed on opposite side surfaces adjacent one end surface; a second pair of slots, each slot of said second pair formed on opposite side surfaces adjacent the other end surface; a first leg member pivotally connected to said work support structure, said first leg member pivotable between a folded position in which said first leg member is substantially folded against said work support structure and a support position in which first leg member is extended substantially away from said work support structure; a second leg member pivotally connected to said work support structure, said second leg member pivotable between a folded position in which said second leg member is substantially folded against said work support structure and a support position in which second leg member is extended substantially away from said work support structure, said first leg member and said second leg member jointly supporting said work support structure when in the support position; a first arm linked by a first pivot limit bar to said first leg member and having a first toothed bar; a second arm linked by a second pivot limit bar to said second leg member and having a second toothed bar; and a pinion gear disposed in engagement with both said first toothed bar and said second toothed bar;
wherein,when either one of said first leg member or said second leg member is moved between said folded position or said support position to the other of said folded position or said support position, the other of said first leg member or said second leg member is caused to move to the same one of said folded position or said support position, and wherein said first pivot limit bar is movably disposed in said first pair of slots and is connected to both said first leg member and said first arm; and
said second pivot limit bar is movably disposed in said second pair of slots and is connected to both said second leg member and said second arm. - View Dependent Claims (6, 7, 8, 9, 10, 11)

14. A workbench comprising:
-
a work support having a work support surface, first and second end surfaces extending downwardly from said work support surface, and first and second side surfaces extending downwardly from said work support surface; a first pair of grooves, a first groove of said first pair of grooves formed in said first side surface and a second groove of said first pair of grooves formed in said second side surface and opposite said first groove formed in said first side surface; a second pair of grooves, a first groove of said second pair of grooves formed in said first side surface and a second groove of said second pair of grooves formed in said second side surface and opposite said first groove formed in said second side surface; a first axle slidably supported in said first pair of grooves; a second axle slidably supported in said second pair of grooves; a first leg member supported by and pivotable about said first axle between a folded position wherein said first leg member is folded adjacent said work support surface and a support position wherein said first leg member is disposed downwardly from said work support surface to support said work support structure; a second leg member supported by and pivotable about said second axle between a folded position wherein said second leg member is folded adjacent said work support surface and a support position wherein said second leg member is disposed downwardly from said work support surface to support said work support; a handle extending from one of said end surfaces and slidably disposed relative to said work support between first and second handle positions; a first rack bar including a rack and connected to said first axle; a second rack bar including a rack and connected to both said second axle and said handle; and a pinion gear disposed between and in engagement with said racks;
whereinwhen said handle is moved between the first and second handle positions, said second rack bar moves in a first direction and rotates said pinion gear to cause said first rack bar to move in a second opposite direction, the movement of said first rack bar causing said first axle to slide along said first pair of grooves and the movement of said second rack bar causing said second axle to slide along said second pair of grooves in an opposite direction to thereby cause said first leg member and said second leg member to both pivot towards either the folded position or the support position. - View Dependent Claims (15, 16, 17, 18)
