Abstract
Abstract A lightweight sawhorse which may be easily collapsed in three transversely aligned directions to form a compact, portable package and thereby facilitate the transport and storage thereof. The dimensions of the sawhorse may also be selectively adjusted to adapt the sawhorse to be used at a variety of job sites and supported upon an irregular or non-planar surface. More particularly, the respective lengths of each of the legs of the sawhorse may be adjusted independently of one another. Moreover, the length of the cross member which extends between opposing pairs of the sawhorse legs may also be adjusted. What is more, each of the sawhorse legs may be rotated independently of one another through an arc between a generally vertical position to a generally horizontal position below the cross member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
An adjustable sawhorse which is collapsible in three transversely aligned directions to form a compact package suitable for transport and storage, said sawhorse comprising: first and second pairs of legs, each of said legs comprising an inner tube and an outer sleeve, said inner tube being movable through said outer sleeve to adjust the length of a respective leg; a cross member extending between said first and second pairs of legs, said cross member comprising an inner and an outer member, said inner member being movable through said outer member to adjust the length of said cross member between said pairs of legs; and means to rotate said legs in a third direction through an arc from a vertical position to a substantially horizontal position.
Claim 2
Dependent Claim
125 words
An adjustable sawhorse which is collapsible in three transversely aligned directions to form a compact package suitable for transport and storage, said sawhorse comprising: first and second pairs of legs, each of said legs comprising an inner tube and an outer sleeve, said inner tube being movable through said outer sleeve to adjust the length of a respective leg; a cross member extending between said first and second pairs of legs, said cross member comprising an inner and an outer member, said inner member being movable through said outer member to adjust the length of said cross member between said pairs of legs; and means to rotate said legs in a third direction through an arc from a vertical position to a substantially horizontal position.
Claim 3
Dependent Claim
43 words
The sawhorse recited in claim 1, further comprising means to pivotally connect said first and second pairs of legs to respective ends of said cross member such that said legs are rotatable in said third direction from the vertical to the horizontal position.
Claim 4
Dependent Claim
72 words
The sawhorse recited in claim 1, wherein the outer sleeve of each leg has a plurality of longitudinally aligned holes formed therethrough and the inner tube of each leg has at least one hole formed therethrough, said sawhorse further comprising means to be removably received through a hole of said outer sleeve and the hole in said inner tube for fixing the position of said inner tube relative to said outer sleeve.
Claim 5
Dependent Claim
60 words
The sawhorse recited in claim 3, wherein said removably received means includes a resilient spring located at the interior of the inner tube of each leg and having a button affixed to one end thereof, the normal bias of said spring forcing said button to be removably received through the respective holes of said inner tube and said outer sleeve.
Claim 6
Dependent Claim
62 words
The sawhorse recited in claim 4, wherein said button extends outwardly from the hole of said outer sleeve to a manually accessible location, a depression of said button against the normal bias of said spring forcing said button inwardly through the hole of said outer sleeve to permit the position of said inner tube to be changed relative to said outer sleeve.
Claim 7
Dependent Claim
46 words
The sawhorse recited in claim 1, further comprising an end bracket connected to each end of said cross member and means to pivotally connect said pairs of legs to respective end brackets to permit said legs to be rotated from the vertical to the horizontal position.
Claim 8
Dependent Claim
56 words
The sawhorse recited in claim 6, wherein said end bracket includes a pair of side plates and an end plate, each leg being pivotally connected to a respective side plate of an end bracket, and each pair of legs engaging a respective end plate of an end bracket to limit the rotational movement of said legs.
Claim 9
Dependent Claim
74 words
The sawhorse recited in claim 1, wherein the outer member of said cross member has a plurality of longitudinally aligned holes formed therethrough and the inner member of said cross member has at least one hole formed therethrough, said sawhorse further comprising means to be removably received through a hole of said outer member and the hole of said inner member for fixing the position of said inner member relative to said outer member.
Claim 10
Dependent Claim
55 words
The sawhorse recited in claim 8, wherein said removably received means includes a resilient spring located at the interior of said inner member and having a button affixed. to one end thereof, the normal bias of said spring forcing said button to be removably received through the respective holes of said inner and outer members.
Claim 11
Dependent Claim
62 words
The sawhorse recited in claim 9, wherein said button extends outwardly from the hole of said outer member to a manually accessible location, a depression of said button against the normal bias of said spring forcing said button inwardly through the hole of said outer member to permit the position of said inner member to be changed relative to said outer member.
