Abstract
Abstract A device for being positioned beneath the back of a human lying supine on a support surface to aline that human's spine. Two upwardly extending elongated ridge members are joined together in a substantially parallel and alined position. Each ridge member has a first end and a second end and an upper surface. The upper surface of each ridge member forms a convex curve substantially at the first end thereof that substantially corresponds to the natural lumbar curve of a human spine, forms a concave curve intermediate the first and second ends thereof that substantially corresponds to the natural thoracic curve of a human spine, and forms a convex curve substantially at the second end thereof that is slightly less than the normal cervical curve of a human spine.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
A device for use in alining a human spine, said device comprising: first and second elongated ridge members and a bridge means for holding said first and second elongated ridge members substantially parallel to and alined with one another at a substantially constant distance apart from one another, each of said ridge members having a first end and a second end and an upper surface, said upper surface of each of said ridge members being continuous and gently curved and forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof and forming a substantially flat, sloping area adjacent said first end thereof.
Claim 2
Independent Claim
113 words
A device for use in alining a human spine, said device comprising: first and second elongated ridge members and a bridge means for holding said first and second elongated ridge members substantially parallel to and alined with one another at a substantially constant distance apart from one another, each of said ridge members having a first end and a second end and an upper surface, said upper surface of each of said ridge members being continuous and gently curved and forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof and forming a substantially flat, sloping area adjacent said first end thereof.
Claim 3
Dependent Claim
26 words
The device of claim 1 in which said upper surface of each of said ridge members forms a convex curve substantially at said second end thereof.
Claim 4
Dependent Claim
38 words
The device of claim 2 in which said convex curve formed by said upper surface of each of said ridge members substantially at said first end thereof substantially corresponds to the natural lumbar curve of a human spine.
Claim 5
Dependent Claim
39 words
The device of claim 3 in which said concave curve formed by said upper surface of each of said ridge members intermediate said first and second ends thereof substantially corresponds to the natural thoracic curve of a human spine.
Claim 6
Dependent Claim
39 words
The device of claim 4 in which said convex curve formed by said upper surface of each of said ridge members substantially at said second end thereof is slightly less than the normal cervical curve of a human spine.
Claim 7
Independent Claim
49 words
The device of claims 1 or 5 in which said first and second ridge members are held apart from one another a distance more than the normal thickness of the spinous processes of a human spine and less than the normal width of the vertebrae of a human spine.
Claim 8
Independent Claim
207 words
A device for being positioned beneath the back of a human lying suprine on a supporting surface to aline that human's spine, said device comprising: (a) a base member for resting on said support surface; (b) a first upwardly extending elongated ridge member positioned on said base member, said first ridge member having a first end and a second end and having an upper surface, said upper surface of said first ridge member forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof, and forming a substantially flat, sloping area adjacent said first end thereof; and (c) a second upwardly extending elongated ridge member positioned on said base member substantially parallel to and alined with said first ridge member and spaced apart from said first ridge member at a substantially constant distance, said second ridge member having a first end and a second end and having an upper surface, said upper surface of said second ridge member being continuous and gently curved and forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof, and forming a substantially flat, sloping area adjacent said first end thereof.
Claim 9
Independent Claim
207 words
A device for being positioned beneath the back of a human lying suprine on a supporting surface to aline that human's spine, said device comprising: (a) a base member for resting on said support surface; (b) a first upwardly extending elongated ridge member positioned on said base member, said first ridge member having a first end and a second end and having an upper surface, said upper surface of said first ridge member forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof, and forming a substantially flat, sloping area adjacent said first end thereof; and (c) a second upwardly extending elongated ridge member positioned on said base member substantially parallel to and alined with said first ridge member and spaced apart from said first ridge member at a substantially constant distance, said second ridge member having a first end and a second end and having an upper surface, said upper surface of said second ridge member being continuous and gently curved and forming a convex curve substantially at said first end thereof, forming a concave curve intermediate said first and second ends thereof, and forming a substantially flat, sloping area adjacent said first end thereof.
Claim 10
Dependent Claim
38 words
The device of claim 7 in which said convex curve formed by said upper surfaces of each of said ridge members substantially at said first ends thereof substantially corresponds to the natural lumbar curve of said human's spine.
Claim 11
Dependent Claim
39 words
The device of claim 8 in which said concave curve formed by said upper surfaces of each of said ridge members intermediate said first and second ends thereof substantially corresponds to the natural thoracic curve of said human's spine.
Claim 12
Dependent Claim
58 words
The device of claim 9 in which said upper surface of each of said ridge members form a convex curve substantially at said second end thereof, said convex curve formed by said upper surfaces of each of said ridge members substantially at said second ends thereof being slightly less than the normal cervical curve of said human's spine.
Claim 13
Independent Claim
49 words
The device of claims 7 or 10 in which said first and second ridge members are positioned apart from one another a distance more than the normal thickness of a spinous process of said human's spine and less than the normal width of a vertebra of said human's spine.
