Abstract

The invention provides a sawhorse comprising a base assembly movable between a folded position for storage and an open position for use and a workpiece support assembly having a workpiece supporting surface which faces upwardly when the base assembly is in the open position for use thereof, said workpiece support assembly being mounted on the base assembly for vertical movement in opposite directions with respect to the base assembly through a range of vertical positions. The base assembly and the workpiece support assembly has a cooperating structure operable to enable the workpiece support assembly to be manually moved in said opposite directions into a selected vertical position with respect to the base assembly, which adjustably engages the workpiece support assembly in the selected vertical position and which is operable to move the workpiece support assembly when the base assembly is in the folded position or in the open position.

First claim

The invention claimed is:

1. A sawhorse configured to support a workpiece, the sawhorse comprising:
a base assembly movable in a movable direction between a folded position for storage and an open position for use;
a workpiece support assembly extending transversely to the movable direction of the base assembly, the workpiece support assembly having a workpiece supporting surface being an uppermost surface of the sawhorse which faces upwardly when the base assembly is in the open position for use thereof, said workpiece support assembly being mounted on the base assembly for movement with respect to the base assembly through a range of heights;
at least one pivoted bar operable to enable the workpiece support assembly to be moved to a selected height with respect to the base assembly;
said pivoted bar being operable to adjustably engage the workpiece support assembly at the selected height,
said pivoted bar being operable to move the workpiece support assembly when the base assembly is in the folded position or in the open position,
wherein the at least one pivoted bar comprises a height adjusting protrusion adjacent to the workpiece support assembly and spaced apart from a pivot, and an engaging protrusion spaced apart from the pivot,
wherein the height adjusting protrusion and the engaging protrusion are spaced apart from each other in different directions along the pivoted bar from the pivot,
wherein the engaging protrusion is operable to engage with a selected one of one or more engaging points in the base assembly in order to adjustably engage the workpiece support assembly at the selected height, and user activation of the height adjusting protrusion disengages the engaging protrusion from the one or more engaging points;
wherein the at least one pivoted bar is disposed within a base assembly channel, and
wherein the height adjusting protrusion and the at least one pivoted bar are configured to be raised or lowered with the workpiece support assembly, and the height adjusting protrusion is configured to remain adjacent to the workpiece supporting surface as the workpiece support assembly moves with respect to the base assembly through the range of heights, such that a user may actuate disengaging the workpiece support assembly from the base assembly and raising the workpiece support assembly relative to the base assembly through same hand simultaneous engagement of the height adjusting protrusion and the workpiece supporting surface.

2. A sawhorse in accordance with claim 1 , wherein at least a part of the at least one pivoted bar is located inside a workpiece support assembly channel.

3. A sawhorse in accordance with claim 1 , comprising two pivoted bars which are spaced apart from each other along a lateral length of the workpiece support assembly.

4. A sawhorse in accordance with claim 1 , wherein the engaging protrusion comprises an undercut groove which lockingly engages with a portion of the selected engaging point while the workpiece support assembly is loaded.

5. A sawhorse in accordance with claim 4 , wherein the one or more engaging points are in the form of holes, notches or ledges.

6. A sawhorse in accordance with claim 1 , further comprising a spread limiting mechanism operatively connected to the base assembly for limiting an unfolding movement of the base assembly when the base assembly is moved into its open position for use, the spread limiting mechanism optionally providing a support surface that functions as a shelf when the base assembly is in its open position for use.

7. A sawhorse in accordance with claim 1 , wherein the height adjusting protrusion comprises a height adjusting knob.
