Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
A programmed hinge assembly comprising: a first hinge plate, a second hinge plate, a hinge joint pivotally connecting said hinge plates, a spring arm between said hinge plates for defining at least one stop position; said spring arm including an anchored portion fixed to said first hinge plate, a control portion including at least one detent in controlling engagement with said second hinge plate, and a connecting portion, said connecting portion partially surrounding the outside of said hinge joint such that said spring arm substantially encompasses said hinge joint.
Claim 2
Dependent Claim
89 words
A programmed hinge assembly comprising: a first hinge plate, a second hinge plate, a hinge joint pivotally connecting said hinge plates, a spring arm between said hinge plates for defining at least one stop position; said spring arm including an anchored portion fixed to said first hinge plate, a control portion including at least one detent in controlling engagement with said second hinge plate, and a connecting portion, said connecting portion partially surrounding the outside of said hinge joint such that said spring arm substantially encompasses said hinge joint.
Claim 3
Dependent Claim
26 words
An assembly as set forth in claim 1 wherein said second hinge plate includes a roller member engaged by said control portion of said spring arm.

Claim 11
Dependent Claim
116 words
A programmed hinge assembly comprising: a first hinge plate, a second hinge plate, a hinge joint pivotally connecting said hinge plates, a triangularly-shaped spring arm between said hinge plates and substantially surrounding said hinge joint for defining at least one stop position, said spring arm including a base portion anchored to said first hinge plate and extending toward and beyond said hinge joint, an intermediate portion connected to said base portion at an angle and thus forming an included angle within which is disposed said hinge joint, and a control portion connected to said intermediate portion and extending generally toward said base portion including at least one detent in controlling engagement with said second hinge plate.
Claim 12
Dependent Claim
116 words
A programmed hinge assembly comprising: a first hinge plate, a second hinge plate, a hinge joint pivotally connecting said hinge plates, a triangularly-shaped spring arm between said hinge plates and substantially surrounding said hinge joint for defining at least one stop position, said spring arm including a base portion anchored to said first hinge plate and extending toward and beyond said hinge joint, an intermediate portion connected to said base portion at an angle and thus forming an included angle within which is disposed said hinge joint, and a control portion connected to said intermediate portion and extending generally toward said base portion including at least one detent in controlling engagement with said second hinge plate.
Claim 13
Dependent Claim
25 words
