Abstract
Abstract A new sawhorse bracket for use with a rectangular cross-section cross-bar, usually of wood, is formed preferably by stamping and subsequent bending from a continuous strip of metal, the bracket comprising a central portion of truncated isosceles triangle shape so as to have two inclined edges, leg supporting portions extending at right angles to the central portion, return portions extending at right angles to the leg-supporting portions, and end portions which engage the sides of the cross-bar. The bracket is fastened to the cross-bar by screws passing through the central portion and a single relatively heavy bolt passing through the end members and the cross-bar. The legs are pivoted to the inclined leg-supporting portions and therefore move from a splayed support position to a stored position alongside the cross-bar to be stable when erected but occupying minimum space when stored. An integral stop is provided for each leg and a gravity operated latch that locks automatically when the sawhorse is upright and unlocks automatically when the sawhorse is inverted. An additional support bar is provided pivotally mounted on two struts which can be supported at different heights in respective bores in the cross-bar.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
A sawhorse bracket for use with an elongated cross-bar of rectangular cross-section comprising: a central end portion of truncated isosceles triangle shape to have corresponding opposite inclined edges; two inclined leg-supporting portions each connected to a respective inclined edge so as to extend longitudinally of the cross-bar; two return portions each connected to a respective leg-supporting portion so as to extend back toward the respective adjacent surface of the cross-bar when present; two end portions each connected to a respective return portion and adapted for fastening to the cross-bar when present; whereby each leg-supporting portion, return portion and the interposed parts of the end portion and the cross-bar when present form a hollow structural leg-support member; and two leg members each pivotally connected to a respective leg-supporting portion for movement between a splayed operative supporting position and a stored position in which it will extend alongside the cross-bar when present.
Claim 2
Dependent Claim
150 words
A sawhorse bracket for use with an elongated cross-bar of rectangular cross-section comprising: a central end portion of truncated isosceles triangle shape to have corresponding opposite inclined edges; two inclined leg-supporting portions each connected to a respective inclined edge so as to extend longitudinally of the cross-bar; two return portions each connected to a respective leg-supporting portion so as to extend back toward the respective adjacent surface of the cross-bar when present; two end portions each connected to a respective return portion and adapted for fastening to the cross-bar when present; whereby each leg-supporting portion, return portion and the interposed parts of the end portion and the cross-bar when present form a hollow structural leg-support member; and two leg members each pivotally connected to a respective leg-supporting portion for movement between a splayed operative supporting position and a stored position in which it will extend alongside the cross-bar when present.
Claim 3
Dependent Claim
39 words
A sawhorse bracket as claimed in claim 1, wherein the said centre end portion, the leg-supporting portions, the return portions and the end portions are all integral with one another formed by stamping from a flat sheet of metal.
Claim 4
Dependent Claim
35 words
A sawhorse bracket as claimed in claim 1, wherein means for fastening the bracket to the cross-bar include a clamp bolt passing through the two end portions and through the interposed part of the cross-bar.
Claim 5
Dependent Claim
45 words
A sawhorse bracket as claimed in claim 2, wherein means for fastening the bracket to the cross-bar include a struck-out part of the centre portion for engagement with an under-surface of the cross-bar when present, and means for fastening the struck-out part of the cross-bar.
Claim 6
Dependent Claim
39 words
A sawhorse bracket as claimed in claim 1, wherein each leg member is of hollow square cross-section with a closure member at the top end and a foot member at the bottom end providing an inclined floor engaging surface.
Claim 7
Dependent Claim
43 words
A sawhorse bracket as claimed in claim 1, and having extending from each leg-supporting portion a respective U-shaped stop member engaged by the upper end of the respective leg-member in the said splayed supporting position to retain the leg member in that position.
Claim 8
Dependent Claim
41 words
A sawhorse bracket as claimed in claim 6, and including a latch member pivotally-connected to each respective leg-supporting portion to engage automatically by gravity the said upper end of the leg member and retain it in engagement with the stop member.
Claim 9
Dependent Claim
32 words
A sawhorse bracket as claimed in claim 7, wherein inversion of the bracket will automatically release the latch member by movement under gravity from the said upper end of the leg member.
Claim 10
Dependent Claim
81 words
A sawhorse bracket as claimed in claim 1, and having integral with each leg-supporting portion and extending therefrom a respective U-shaped stop member engaged by the upper end of the respective leg-member in the said splayed supporting position to retain the leg member in that position, the bracket also including a latch member pivotally-connected to each respective leg-supporting portion to engage automatically by gravity the said upper end of the leg member and retain it in engagement with the stop member.
Claim 11
Dependent Claim
70 words
A sawhorse bracket as claimed in claim 1, in combination with a support bar comprising an elongaged support bar member, two strut members each adapted to move in respective spaced vertical bores in the cross-bar, two yoke members each connected to a respective strut member and pivotally connected to the support bar member, and means for supporting each strut member in its respective bore at different positions along its length.
