Abstract
Abstract A slant board formed of panels which are selectively disposed in a common plane or folded back against each other. Longitudinally extending angle members pivotally connect the two panels together and also provide a hinge assembly with a transverse pivot axis, offset from the abutting edges of the panels, which limit pivoting movement so as to align the panels in a common plane. Adjustable legs are carried by one of the panels and a foot strap is provided for arresting the feet of a person utilizing the slant board. Transportation straps provide a handle for carrying the folded board.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
An exercising slant board comprising a pair of rectangular substantially rigid panels; a hinge assembly securing said panels together, said panels having proximal transverse edges, said hinge assembly having a transverse hinge axis approximately parallel to said proximal edges below one of said panels, said axis being offset longitudinally from said proximal edges; said panels, in their set-up position, being in approximately a common plane with their proximal edges in abutting relationship, said panels being pivotable about said transverse axis to a folded position adjacent to each other; and leg means for supporting sand slant board.
Claim 2
Dependent Claim
96 words
An exercising slant board comprising a pair of rectangular substantially rigid panels; a hinge assembly securing said panels together, said panels having proximal transverse edges, said hinge assembly having a transverse hinge axis approximately parallel to said proximal edges below one of said panels, said axis being offset longitudinally from said proximal edges; said panels, in their set-up position, being in approximately a common plane with their proximal edges in abutting relationship, said panels being pivotable about said transverse axis to a folded position adjacent to each other; and leg means for supporting sand slant board.
Claim 3
Dependent Claim
63 words
The exercising slant board defined in claim 1 wherein each of said panels includes a flat wooden base and a flat resilient member disposed over said base, said base and said member each being of approximately the same dimensions and a cover extending over said flat resilient member, said cover being secured to the lower surface of said base, adjacent the edges thereof.
Claim 4
Dependent Claim
30 words
The exercising slant board defined in claim 1 including means for supporting legs disposed outwardly adjacent the edges of one of said panels and legs adjustably carried by said means.
Claim 5
Dependent Claim
86 words
The exercising slant board defined in claim 3 wherein said means includes a U-shaped bar, having a base which extends transversely across the bottom portion of one of said panels and is secured thereto, and flanges extending from the ends of said base parallel to each other on opposite sides of said panel, sleeves respectively secured to said flanges of said strap, said sleeves respectively slideably received said first mentioned legs and means for arresting the slideable movement of the first mentioned legs in said sleeves.
Claim 6
Dependent Claim
70 words
The exercising slant board defined in claim 1 wherein said hinge assembly includes a pair of opposed parallel first struts secured to the bottom surface of one of said panels and a pair of opposed parallel second struts secured to the bottom surface of the other of said panels, said struts overlapping each other below one of said panels and pivot means passing through the overlapped portions of the struts.
Claim 7
Dependent Claim
44 words
The exercising slant board defined in claim 5 wherein said struts are each angle irons and wherein said first struts are provided with abutment shoulders against which portions of the second strut abut when said panels are disposed in parallel relationship to each other.
Claim 8
Dependent Claim
48 words
The exercising slant board defined in claim 5 including leg receiving means secured to one of said panels and legs slideably received within said means, the other of said panels being foldable against one of said panels and being disposed within said leg receiving means, when so folded.
Claim 9
Dependent Claim
22 words
The exercising slant board defined in claim 5 wherein said struts are disposed adjacent to each other when said panels are folded.
Claim 10
Dependent Claim
35 words
The exercising slant board defined in claim 8 including a foot arresting strap extending across the end portion of one of said panels for receiving the feet of a person utilizing the exercising slant board.
Claim 11
Dependent Claim
22 words
The exercising slant board defined in claim 9 including a resilient bumper across the bottom edge of the other of said panels.
