Abstract
A folding sawhorse is formed from a pair of substantially identical rectangular frames. The frames are constructed from four substantially identical wooden members via lap joints to make a smooth construction. The frames are also pivotally joined together by a pair of hinges fixedly coupled to top portions thereof. A flexible member or chain extends between the frames, but is displaced from the hinges. The hinges allow for pivotal movement of the frames, while the chain limits the range of pivotal movement.
Claims9
A folding sawhorse, comprising:
- a first frame having upper, lower, and side members, each member having first and second end portions defined by notched portions with said end portions of said upper and lower members being coupled to the end portions of one of the side members at a top and bottom edge thereof, respectively via a lap joint, the first frame members forming a generally closed polygon;
- a second frame having upper, lower, and side members, each member having first and second end portions defined by notched portions with said end portions of said upper and lower members being coupled to the end portions of one of the side members at a top and bottom edge thereof, respectively via a lap joint, the second frame members forming a generally closed polygon;
- a hinge extending between a top portion of the upper member of the first frame and a top portion of the upper member of the second frame to allow said frames to pivot about an axis adjacent said upper member top portions between a first position wherein said first and second frames are substantially parallel and adjacent and a second position wherein said first and second frames are spaced apart;
- and
- a flexible member extending between said first and second frames displaced from said hinge.

- a hinge extending between a top portion of the upper member of the first frame and a top portion of the upper member of the second frame to allow said frames to pivot about an axis adjacent said upper member top portions between a first position wherein said first and second frames are substantially parallel and adjacent and a second position wherein said first and second frames are spaced apart;
- and
- a flexible member extending between said first and second frames displaced from said hinge to limit pivoting movement of said first and second frames.
