Abstract A collapsible sawhorse comprising a beam, leg-supporting brackets having downwardly diverging sides, said sides defining leg receiving channels, legs mounted pivotally in said channels for movement lateral to the beam, the brackets being pivotally mounted on the beam so that each bracket and the legs attached to it are movable in conjunction from a folded position contiguous and parallel to the beam to an extended position at substantially right angles to the beam. The legs of the sawhorse may be adapted to support a tray at about their vertical midpoints.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
214 words
A collapsible sawhorse comprising: a horizontal beam, substantially U-shaped leg-supporting brackets pivotally secured to said beam at each end thereof, each of said brackets having downwardly diverging sides connected by a web facing outwardly toward the beam end and inwardly turned flanges which in conjunction with the said web delineate a U-shaped channel on each diverging side adapted to receive a leg, the said U-shaped channels in each bracket facing each other, a leg fastened pivotally in each of said U-shaped channels for movement inwardly lateral to said beam from a position adjacent the diverging side of said bracket, which side forms the bottom of said U-shaped channel, to a position substantially perpendicular to the said beam, each of the said leg-supporting brackets and the two legs fastened thereto being movable, in conjunction from a folded position contiguous and parallel to the said beam to an extended position at substantially right angles thereto, the legs in one leg-supporting bracket being pivoted at a point in the said U-shaped channels nearer the top of the bracket and closer to the beam than the legs fastened in the other bracket, whereby, when the sawhorse is in folded position, all four legs nest together in parallel and contiguous relationship with the said beam and with each other,
Claim 2
Dependent Claim
214 words
A collapsible sawhorse comprising: a horizontal beam, substantially U-shaped leg-supporting brackets pivotally secured to said beam at each end thereof, each of said brackets having downwardly diverging sides connected by a web facing outwardly toward the beam end and inwardly turned flanges which in conjunction with the said web delineate a U-shaped channel on each diverging side adapted to receive a leg, the said U-shaped channels in each bracket facing each other, a leg fastened pivotally in each of said U-shaped channels for movement inwardly lateral to said beam from a position adjacent the diverging side of said bracket, which side forms the bottom of said U-shaped channel, to a position substantially perpendicular to the said beam, each of the said leg-supporting brackets and the two legs fastened thereto being movable, in conjunction from a folded position contiguous and parallel to the said beam to an extended position at substantially right angles thereto, the legs in one leg-supporting bracket being pivoted at a point in the said U-shaped channels nearer the top of the bracket and closer to the beam than the legs fastened in the other bracket, whereby, when the sawhorse is in folded position, all four legs nest together in parallel and contiguous relationship with the said beam and with each other,
Claim 3
Dependent Claim
56 words
The collapsible sawhorse of claim 1 adapted to receive a tray or shelf wherein the inside edge of each leg at about the midpoint is characterized by the presence of a notch and a plate fastened to said leg below said notch, the upper end of said plate extending above the lower end of said notch.
Claim 4
Dependent Claim
128 words
The collapsible sawhorse of claim 2 in combination with a tray, said tray comprising a shelf and side and end rails, said side and end rails being joined by brackets having wing portions dimensioned and angulated to lie flush against the inside facing portions of the downwardly diverging legs, said side rails of said tray being dimensioned to lie in the same plane as the diverging legs and to abut said legs, said side rails carrying at each end of the bottom thereof a plate extending beyond the end of the side rail where it abuts said legs, said extension having a downwardly turned portion, the said extension protruding into the notch in each leg with said downwardly turned portion engaging the leg-mounted plate extending into said notch.
Claim 5
Dependent Claim
35 words
The collapsible sawhorse and tray of claim 3 wherein the wing portion of the tray brackets and the legs are drilled to receive, upon alignment, fastening means for fastening said tray-carrying brackets to said legs.
