Abstract
Abstract A collapsible sawhorse is provided in which the legs are pivotally mounted relative to each other for movement between a conventional load supporting sawhorse position and a collapsed position. The collapsible sawhorse comprises a wide work supporting beam coextensive with the length and width of the device. A pair of rope lengths are provided to limit pivotal movement of the sawhorse legs. A brace selectively spans the legs to prevent inadvertent movement of the legs toward each other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
254 words
A collapsible sawhorse moving between storage and load supporting positions, comprising an elongate beam of generally pentagonal cross-section having a length dimension, a width dimension and a thickness dimension, the beam having a planar upper surface corresponding to the base of the pentagon, a pair of generally parallel sides intersecting the upper surface and corresponding to the sides of the pentagon and first and second downwardly extending converging bottom faces intersecting the parallel sides; a first pair of generally straight parallel spaced legs having a long dimension and an end generally perpendicular to the long dimension, the end abutting the first bottom face of the base; means rigidly connecting the end and the first bottom face; a second pair of generally straight parallel spaced legs having a long dimension and an end generally perpendicular to the long dimension, the second legs being of generally the same size as the first legs; a pair of hinges connecting the first and second legs including a first arm connected to the first leg, a second arm connected to the second leg and a pivot connection located adjacent the convergence of the base bottom faces; the arrangement between the hinges and the second legs being such as to abut the ends of the second legs against the second bottom face in load supporting position of the sawhorse; means for limiting pivotal movement of the second legs relative to the first legs in a spreading direction; and means for selectively preventing pivotal movement of the legs toward each other.
Claim 2
Dependent Claim
254 words
A collapsible sawhorse moving between storage and load supporting positions, comprising an elongate beam of generally pentagonal cross-section having a length dimension, a width dimension and a thickness dimension, the beam having a planar upper surface corresponding to the base of the pentagon, a pair of generally parallel sides intersecting the upper surface and corresponding to the sides of the pentagon and first and second downwardly extending converging bottom faces intersecting the parallel sides; a first pair of generally straight parallel spaced legs having a long dimension and an end generally perpendicular to the long dimension, the end abutting the first bottom face of the base; means rigidly connecting the end and the first bottom face; a second pair of generally straight parallel spaced legs having a long dimension and an end generally perpendicular to the long dimension, the second legs being of generally the same size as the first legs; a pair of hinges connecting the first and second legs including a first arm connected to the first leg, a second arm connected to the second leg and a pivot connection located adjacent the convergence of the base bottom faces; the arrangement between the hinges and the second legs being such as to abut the ends of the second legs against the second bottom face in load supporting position of the sawhorse; means for limiting pivotal movement of the second legs relative to the first legs in a spreading direction; and means for selectively preventing pivotal movement of the legs toward each other.
Claim 3
Dependent Claim
19 words
The sawhorse of claim 1 wherein an extension of the convergence of the bottom faces intersects the pivot connection.
Claim 4
Dependent Claim
39 words
The sawhorse of claim 1 further comprising a first brace connecting the first legs together, the first brace comprising a side abutting the first bottom face of the base and means connecting the first brace and the first leg.
Claim 5
Dependent Claim
15 words
Th sawhorse of claim 3 further comprising means connecting the first brace and the beam.
Claim 6
Dependent Claim
31 words
The sawhorse of claim 4 further comprising a second brace connecting the second legs together, the second brace comprising a side abutting the second bottom face in the lead supporting position.
Claim 7
Dependent Claim
35 words
Th sawhorse of claim 5 wherein the limiting means prevents spreading pivotal movement of the first and second legs beyond the position where the second leg ends abut the second bottom face of the base.
Claim 8
Dependent Claim
16 words
The sawhorse of claim 1 wherein the thickness dimension is substantially less than the width dimension.
Claim 9
Dependent Claim
29 words
The sawhorse of claim 1 wherein the beam comprises a section of pentagonal cross-section where the bottom faces converge at a location corresponding to the apex of the pentagon.
Claim 10
Dependent Claim
22 words
The sawhorse of claim 1 wherein the beam is of uniform generally pentagonal cross-section and the bottom faces terminate short of convergence.
