Abstract
Abstract A foldable sawhorse is disclosed having a main set of leg members with a beam across the upper edges thereof, and a shorter, supporting set of leg members pivotally secured to the main leg members. Strut members extend between the main and supporting legs on each side of the sawhorse, the struts being foldable as the sets of leg members are folded together, the legs and struts assuming a nesting relationship for presenting a thin, folded profile for storage and/or transport. The center support beam is vertically aligned with the midpoint of the open legs to evenly distribute the weight between the uneven length sets of leg members.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
260 words
A foldable sawhorse having operative and storage positions and adapted to be positioned on a base, comprising main leg members with supporting leg members pivotally joined at pivot points to said main leg members near the upper ends thereof, said supporting leg members being shorter than said main leg members and forming an inverted V-shaped structure in combination with said main leg members when in said operative position and wherein the distance along said main leg members between said pivot points and the lower ends of said main leg members is less than the distance along said supporting leg members between said pivot points and the lower ends of said supporting leg members, foldable strut means extending between and pivotally secured to said main leg members and said supporting leg members at each side of said V-shaped structure for selectively maintaining said leg members in said operative position, said strut means having right and left bar means pivotally secured together near their opposed end portions opposite the connection to said leg members and wherein the points of connection of said strut means to said main leg members are disposed below the points of connection of said strut means to said supporting leg members for disposing said strut means at an angle relative to said base, a support member secured to and extending between the upper ends of said main leg members and in substantially vertical alignment with the midpoint between said leg members when in said operative position, and pad means secured to the lower ends of said leg members.
Claim 2
Dependent Claim
260 words
A foldable sawhorse having operative and storage positions and adapted to be positioned on a base, comprising main leg members with supporting leg members pivotally joined at pivot points to said main leg members near the upper ends thereof, said supporting leg members being shorter than said main leg members and forming an inverted V-shaped structure in combination with said main leg members when in said operative position and wherein the distance along said main leg members between said pivot points and the lower ends of said main leg members is less than the distance along said supporting leg members between said pivot points and the lower ends of said supporting leg members, foldable strut means extending between and pivotally secured to said main leg members and said supporting leg members at each side of said V-shaped structure for selectively maintaining said leg members in said operative position, said strut means having right and left bar means pivotally secured together near their opposed end portions opposite the connection to said leg members and wherein the points of connection of said strut means to said main leg members are disposed below the points of connection of said strut means to said supporting leg members for disposing said strut means at an angle relative to said base, a support member secured to and extending between the upper ends of said main leg members and in substantially vertical alignment with the midpoint between said leg members when in said operative position, and pad means secured to the lower ends of said leg members.

A foldable sawhorse as defined in claim 1 in which said right and left bar means are substantially parallel to one another in separate planes and form a V-shaped member when in extended position for resisting unintentional folding of said strut means.
Claim 4
Dependent Claim
47 words

Claim 5
Dependent Claim
33 words
A foldable sawhorse as defined in claim 3 in which said main and supporting sets of leg members include pad means on the lower edge thereof for supporting said sets of leg members.
Claim 6
Dependent Claim
56 words
A foldable sawhorse as defined in claim 1 and including an operator bar having one end secured to one of said strut means and an opposite end secured to the other of said strut means for raising said strut means to a folded position and drawing said sets of leg members together for folding said sawhorse.
Claim 7
Dependent Claim
234 words
A foldable sawhorse having an operative position forming an inverted V-shaped structure and adapted to be positioned on a base, and a storage position, said sawhorse comprising first leg members having a bar means secured to and extending between the upper ends thereof, said bar means having an upper surface disposed parallel to the base when the sawhorse is in the operative position and an angular disposition when the sawhorse is in the storage position, second leg members shorter than said first leg members and having upper ends pivotally securedd to each of said first leg members at pivot points below the upper ends thereof for supporting said first leg members and wherein the distance along said first leg members between said pivot points and the lower ends of said first leg members is less than the distance along said second leg members between said pivot points and the lower ends of said second leg members, strut means extending between said first and second pivotally connected leg members at each side of the sawhorse, each strut means having generally parallel bars in separate planar relationship with one end pivotally secured to said first and second leg members respectively, and opposite ends pivotally secured to one another substantially in vertical alignment with said bar means for equally distributing applied weight between said leg members, and feet secured to the lower ends of said leg members.
Claim 8
Dependent Claim
234 words
A foldable sawhorse having an operative position forming an inverted V-shaped structure and adapted to be positioned on a base, and a storage position, said sawhorse comprising first leg members having a bar means secured to and extending between the upper ends thereof, said bar means having an upper surface disposed parallel to the base when the sawhorse is in the operative position and an angular disposition when the sawhorse is in the storage position, second leg members shorter than said first leg members and having upper ends pivotally securedd to each of said first leg members at pivot points below the upper ends thereof for supporting said first leg members and wherein the distance along said first leg members between said pivot points and the lower ends of said first leg members is less than the distance along said second leg members between said pivot points and the lower ends of said second leg members, strut means extending between said first and second pivotally connected leg members at each side of the sawhorse, each strut means having generally parallel bars in separate planar relationship with one end pivotally secured to said first and second leg members respectively, and opposite ends pivotally secured to one another substantially in vertical alignment with said bar means for equally distributing applied weight between said leg members, and feet secured to the lower ends of said leg members.
