Abstract
Abstract A sturdy, collapsible saw horse has legs which move between collapsed and extended positions, and flexible connectors limit leg movement at extended positions. The saw horse may also have two horizontal frame members which pivotally support the legs, the frame members hinged together for relative lateral movement limited by tensioning of the flexible connectors.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
140 words
In a saw horse, the combination comprising (a) generally horizontally extending upper frame structure, (b) two pairs of legs pivotally connected to the frame structure to independently and swingably move toward each other between extended positions in which the frame structure is supported on the legs, and collapsed positions proximate that structure, and (c) flexible connector means operatively connected with the legs and the upper frame structure to limit such independent swinging movement of the pairs of legs relatively away from one another at said extended positions, (d) said upper frame structure including two longitudinally elongated frame members, the two legs of each of said pairs respectively connected to said members, and hinge means interconnecting said members to pivot laterally relative to one another, said flexible connector means also connected with said members to limit said member relative lateral pivoting.
Claim 2
Dependent Claim
140 words
In a saw horse, the combination comprising (a) generally horizontally extending upper frame structure, (b) two pairs of legs pivotally connected to the frame structure to independently and swingably move toward each other between extended positions in which the frame structure is supported on the legs, and collapsed positions proximate that structure, and (c) flexible connector means operatively connected with the legs and the upper frame structure to limit such independent swinging movement of the pairs of legs relatively away from one another at said extended positions, (d) said upper frame structure including two longitudinally elongated frame members, the two legs of each of said pairs respectively connected to said members, and hinge means interconnecting said members to pivot laterally relative to one another, said flexible connector means also connected with said members to limit said member relative lateral pivoting.
Claim 3
Dependent Claim
20 words
The combination of claim 1 wherein said flexible connector means becomes taut when said legs arrive at said extended positions.
Claim 4
Dependent Claim
57 words
The combination of claim 1 wherein said flexible connector means extends from said members to said legs of each pair, and between the legs of each pair; and becomes taut when said legs arrive at said extended positions and when the legs of each pair have been spread apart accompanied by said lateral pivoting of said members.
Claim 5
Dependent Claim
15 words
The combination of claim 2 wherein said flexible connector means comprises at least one cable.
Claim 6
Dependent Claim
15 words
The combination of claim 3 wherein said flexible connector means comprises at least one cable.
Claim 7
Dependent Claim
48 words
The combination of claim 1 including retainers connecting the upper end portions of said legs to said members, one of the two legs pivotally connected to each of said members extending closer to that member than the other of said two legs, in collapsed positions of said legs.
Claim 8
Dependent Claim
24 words
The combination of claim 6 including a spacer located between said member and the upper end portion of the other of said two legs.
Claim 9
Dependent Claim
19 words
The combination of claim 3 wherein said members and said legs define holes to which the connector means extend.
Claim 10
Dependent Claim
60 words
The combination of claim 8 wherein said connector means extends between the lower portions of the legs of one pair to said members near the upper portion of the legs of the other pair, and between the lower portions of the legs of the other pair to said members near the upper portions of the legs of the one pair.
Claim 11
Dependent Claim
20 words
The combination of claim 9 wherein the connector means wraps at least partially about said lower portions of the legs.
Claim 12
Dependent Claim
153 words
In a saw horse, the combination comprising (a) generally horizontally and longitudinally extending upper frame structure, (b) two pairs of legs pivotally connected to the frame structure to independently and swingably move toward each other between downward extended positions in which the frame structure is supported on the legs and upper collapsed positions proximate that structure, and (c) flexible connector means operatively connected with the legs and the upper frame structure to limit such indenpendent swinging movement of the pairs of legs relatively away from one another at said extended positions, (d) said upper frame structure including two longitudinally elongated opposite sides, the two legs of each of said pairs respectively connected to said frame structure to diverge laterally and downwardly from said opposite sides in said extended positions, said flexible connector means also connected with said frame structure and legs to limit the extent of leg lateral divergence in said extended positions.
Claim 13
Dependent Claim
153 words
In a saw horse, the combination comprising (a) generally horizontally and longitudinally extending upper frame structure, (b) two pairs of legs pivotally connected to the frame structure to independently and swingably move toward each other between downward extended positions in which the frame structure is supported on the legs and upper collapsed positions proximate that structure, and (c) flexible connector means operatively connected with the legs and the upper frame structure to limit such indenpendent swinging movement of the pairs of legs relatively away from one another at said extended positions, (d) said upper frame structure including two longitudinally elongated opposite sides, the two legs of each of said pairs respectively connected to said frame structure to diverge laterally and downwardly from said opposite sides in said extended positions, said flexible connector means also connected with said frame structure and legs to limit the extent of leg lateral divergence in said extended positions.
Claim 14
Dependent Claim
43 words
The combination of claim 11 wherein said flexible connector means comprises flexible lines extending from said upper frame structure to the legs of each pair, and between the legs of each pair, to become taut when the legs arrive at said extended positions.
