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.

First claim

We claim:

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.

2. The workbench recited in claim 1 , said first leg member and said second leg member each comprising a pair of legs connected by a crossbar, wherein a crossbar of said first leg member is overlapped by the second leg member when the first leg member and the second member are in said first position.

3. The workbench recited in claim 1 further comprising a handle lock pin selectively retractable from a handle lock aperture formed on the handle and configured to secure one or both of said first leg member and said second leg member in at least one of said first position or said second position.

4. The workbench recited in claim 1 further comprising a plurality of apertures formed in the work support structure configured to receive one or more of clamps or accessories therethrough.

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.

6. The workbench recited in claim 5 , wherein;
said first leg member comprises a first pair of legs and a first pivot bar extending between said first pair of legs and around which said first leg member may be pivoted between said folded position and said support position; and
said second leg member comprises a second pair of legs and a second pivot bar extending between said second pair of legs and around which said second leg member may be pivoted between said first folded position and said support position.

7. The workbench recited in claim 5 further comprising:
a strap connected to one of said first pivot limit bar and said second pivot limit bar, wherein, a user may pull said strap and simultaneously move both said first leg member and said second leg member from said support position to said folded position.

8. The workbench recited in claim 5 further comprising:
an aperture formed in said first leg member; and
a latch including an actuator and a catch, said catch extending from said work support structure and into said aperture when said first leg member is in the folded position to lock said first leg member in said folded position; wherein,
actuation of said actuator removes said catch from said aperture to allow said first leg member to be moved to the support position.

9. The workbench recited in claim 5 further comprising:
an arm aperture disposed in said first arm;
a latch including an actuator and a catch, said catch extending from said work support structure and into said arm aperture when said first leg member is in the support position to lock said first leg member in said support position; wherein,
actuation of said actuator removes said catch from said arm aperture to allow said first leg member to be moved to the folded position.

10. The workbench recited in claim 9 further comprising:
a leg member aperture formed in said first leg member; and
a second catch included in said latch, said second catch extending from said work support structure and into said leg member aperture when said first leg member is in the folded position to lock said first leg member in the folded position; wherein,
actuation of said actuator removes said second catch from said leg member aperture to allow said first leg member to be moved to the support position.

11. The workbench recited in claim 10 further comprising:
a rotatable shaft; wherein,
said catch and said second catch are disposed on and rotate with said shaft, said shaft spring biased to bias said catch in a first position in which said catch may be received in said arm aperture and to bias said second catch in a second position in which said second catch may be received in said first leg member aperture, said actuator comprising a push button which may be pushed to rotate said shaft against the spring bias to rotate said catch away from the first position and said second catch away from the second position.

12. The workbench recited in claim 1 wherein:
said handle is slidably disposed between a first handle position and a second handle position relative to said work support structure, said handle linked to said first leg member; wherein,
when said handle is in the first handle position, said first leg member and said second leg member are in their said first positions, and when said handle is in the second handle position, said first leg member and said second leg member are in their said second positions, and movement of said handle between the first handle position and the second handle position causes corresponding movement of said first leg member and said second leg member between their first positions and their second positions.

13. The workbench recited in claim 12 further comprising:
two side surfaces forming part of said work support structure, said handle extending from a first of said side surfaces; and
a first wheel and a second wheel disp
