Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 123 words
An angle adjusting device for a display device comprising: a channel type bearing means provided with a fixing portion having at least two slits in projected positions of a pair of coil springs to be mounted on the bearing; a rotatable axis rotatably mounted on said bearing means; and at least a pair of coil springs, closely wound on said rotatable axis and each having a hook portion inserted in a slit of said bearing, wherein each of the springs is dimensioned to provide a locking force on said rotatable axis when the axis is turned in one direction relative to the respective spring and to release said force when the axis is turned in an opposite direction relative to the respective spring.
Claim 2
Dependent Claim 123 words
An angle adjusting device for a display device comprising: a channel type bearing means provided with a fixing portion having at least two slits in projected positions of a pair of coil springs to be mounted on the bearing; a rotatable axis rotatably mounted on said bearing means; and at least a pair of coil springs, closely wound on said rotatable axis and each having a hook portion inserted in a slit of said bearing, wherein each of the springs is dimensioned to provide a locking force on said rotatable axis when the axis is turned in one direction relative to the respective spring and to release said force when the axis is turned in an opposite direction relative to the respective spring.
Claim 3
Dependent Claim 31 words
An angle adjusting device according to claim 1, wherein said channel type bearing means comprises two single side bearings each with a slit in a projected position of said coil springs;
Claim 4
Dependent Claim 14 words
An angle adjusting device according to claim 1, wherein said rotatable axis is solid.
Claim 5
Dependent Claim 16 words
An angle adjusting device according to claim 1, wherein said rotatable axis is of tubular form.
Claim 6
Dependent Claim 19 words
An angle adjusting device according to claim 1, wherein at least a pair of identical coil springs are used.
Claim 7
Dependent Claim 17 words
An angle adjusting device according to claim 1, wherein of the respective coil springs are wound reversely.
Claim 8
Dependent Claim 19 words
An angle adjusting device according to claim 1, wherein at least one coil spring is made of rectangular wire.
Claim 9
Dependent Claim 18 words
An angle adjusting device according to claim 1, wherein the springs are each wound in the same direction.
Claim 10
Dependent Claim 17 words
An angle adjusting device according to claim 1, wherein the springs are each made of round wire.
Claim 11
Dependent Claim 20 words
An angle adjusting device according to claim 1 wherein the axis has a non-circular projecting portion for applying torque thereto.
