Collapsible sawhorse

Claim 2

A collapsible sawhorse comprising a hollow elongate beam, a pair of generally parallel legs fixedly secured to and extending transversely from said beam adjacent to opposite beam ends, an additional pair of legs hingedly connected to said beam adjacent to opposite beam ends for swinging movement between a collapsed position adjacent to said first mentioned legs and a set-up position diverging from said first-mentioned legs, limit means limiting movement of said additional pair of legs to said collapsed and set-up positions, clamping means comprising end members, one of which is adapted to be removably engageable in the hollow of said beam, and having its other end member extending in spaced relation over said beam, and a clamping element carried by said other end member for clamping and releasing movement toward and away from said beam.

Claim 3

A collapsible sawhorse according to claim 1, in combination with a bearing saddle removably secured on said beam for rotatably supporting a shaft.

Claim 4

A collapsible sawhorse according to claim 1, wherein said limit means comprise pivotal linkage means connected between each pair of adjacent legs to limit swinging movement of adjacent legs away from each other.

Claim 5

A collapsible sawhorse according to claim 1, in combination with telescopically extensile and retractile feet on said legs for adjustment to ground conditions.

Claim 6

A collapsible sawhorse according to claim 1, said hollow beam being tubular and having one end open, and said clamping means having one end member adjustably insertable into said tubular beam through said one beam end.

Claim 7

A collapsible sawhorse according to claim 8, said tubular hollow beam being of noncircular cross-section, and said end member being nonrotatably slidable in said beam, said clamping element comprising a threaded member extending threadedly through said other end member for releasable clamping engagement with an article resting on said beam.

Claim 8

A collapsible sawhorse according to claim 1, wherein said limit means comprise pivotal linkage means connected between each pair of adjacent legs to limit swinging movement of adjacent legs away from each other.

Claim 9

A collapsible sawhorse comprising an elongate beam, a pair of generally parallel legs fixedly secured to and extending transversely from said beam adjacent to opposite beam ends, an additional pair of legs hingedly connected to said beam adjacent to opposite beam ends for swinging movement between a collapsed position adjacent to said first mentioned legs and a set-up position diverging from said first-mentioned legs, limit means limiting movement of said additional pair of legs to said collapsed and set-up positions, the hinged connection of said additional pair of legs to said beam comprising bushing means and associated pin means extending through said bushing means, at least one of said bushing means being fixedly secured to each of said additional pair of legs and the other of said bushing means being fixedly secured to said elongate beam, thereby permitting the swinging movement of said additional pair of legs to said collapsed and set-up positions.

Claim 10

A collapsible sawhorse comprising an elongate beam, a pair of generally parallel legs fixedly secured to and extending transversely from said beam adjacent to opposite beam ends, an additional pair of legs hingedly connected to said beam adjacent to opposite beam ends for swinging movement between a collapsed position adjacent to said first mentioned legs and a set-up position diverging from said first-mentioned legs, limit means limiting movement of said additional pair of legs to said collapsed and set-up positions, the hinged connection of said additional pair of legs to said beam comprising bushing means and associated pin means extending through said bushing means, at least one of said bushing means being fixedly secured to each of said additional pair of legs and the other of said bushing means being fixedly secured to said elongate beam, thereby permitting the swinging movement of said additional pair of legs to said collapsed and set-up positions.

Claim 11

A collapsible sawhorse according to claim 8, in combination with a bearing saddle removably secured on said beam for rotatably supporting a shaft.

Claim 12

A collapsible sawhorse according to claim 8, in combination with telescopically extensile and retractile feet on said legs for adjustment to ground conditions.

Claim 13

A collapsible sawhorse according to claim 8, said beam being hollow, and clamping means comprising end members, one of which is adapted to be removably engageable in the hollow of said beam, and having its other end member extending in spaced relation over said beam, and a clamping element carried by said other member for clamping and releasing movement toward and away from said beam.

Claim 14

A collapsible sawhorse according to claim 11, said hollow beam being tubular and having one end opened, and said claimping means having one end member adjustably insertable into said tubular beam through said one beam end.

Claim 15

A collapsible sawhorse according to claim 12, said tubular hollow beam being of noncircular cross-section, and said end member being nonrotatably slidable in said beam, said clamping element comprising a threaded member extending threadedly through said other end member for releasable clamping engagement with an article resting on said beam.
