Abstract
Abstract A collapsible sawhorse includes a horizontal load supporting beam which is pivoted in the center thereof. A pair of legs is disposed at each end of the beam and each is mounted for compound pivotal movement between a first load supporting position and a second position nested within the confines of the beam. When in its load supporting position, the sawhorse is of conventional size. When in its collapsed position, the volume of the sawhorse corresponds to the volume of the horizontal beam.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
A collapsible sawhorse comprising a beam for supporting a load including first and second sections pivoted together for movement between a first position in which an upper surface of the sections are coplanar and a second position in which the upper sections are parallel; two pairs of legs, at opposite ends of the beam, for supporting the beam in the first position thereof; and means pivotally connecting each pair of legs to the beam for movement between a first load supporting position and a second position parallel to the beam sections, including means mounting each leg for pivotal movement toward the other leg of its pair; and means mounting each pair of legs for pivotal movement about an axis perpendicular to the upper section surface.
Claim 2
Dependent Claim
125 words
A collapsible sawhorse comprising a beam for supporting a load including first and second sections pivoted together for movement between a first position in which an upper surface of the sections are coplanar and a second position in which the upper sections are parallel; two pairs of legs, at opposite ends of the beam, for supporting the beam in the first position thereof; and means pivotally connecting each pair of legs to the beam for movement between a first load supporting position and a second position parallel to the beam sections, including means mounting each leg for pivotal movement toward the other leg of its pair; and means mounting each pair of legs for pivotal movement about an axis perpendicular to the upper section surface.
Claim 3
Dependent Claim
26 words
The collapsible sawhorse of claim 1 wherein the second mentioned mounting means comprises a bracket and means mounting the bracket for pivotal movement about the axis.
Claim 4
Dependent Claim
38 words
The collapsible sawhorse of claim 2 wherein the first mentioned mounting means includes means mounting the legs to the bracket for pivotal movement about an axis perpendicular to the axis which is perpendicular to the upper section surface.
Claim 5
Dependent Claim
26 words
The collapsible sawhorse of claim 3 wherein the legs of each pair are nestable and further include a collapsible brace interconnecting the legs of each pair.
Claim 6
Dependent Claim
29 words
The collapsible sawhorse of claim 4 wherein the legs of each pair include first and second telescoping sections and means for retaining the leg sections in an extended position.
Claim 7
Dependent Claim
33 words
The collapsible sawhorse of claim 5 wherein the beam sections include side walls transverse to the upper surfaces, the legs residing within the confines of the side walls in the second position thereof.
Claim 8
Dependent Claim
24 words
The collapsible sawhorse of claim 6 further comprising a latch for securing the beam sections in the first position and in the second position.
Claim 9
Dependent Claim
53 words
The collapsible sawhorse of claim 7 wherein the latch comprises a lever pivoted to one of the beam sections, the other beam section forming a receiver for the latch in the latched position, the same lever and receiver being effective to latch the beam sections in both the first and second positions thereof.
Claim 10
Dependent Claim
47 words
The collapsible sawhorse of claim 1 wherein the last mentioned mounting means includes means providing a tight interference fit in the first position of the leg pairs and a loose fit, allowing substantially more play in the mounting means, in the second position of the leg pairs.
