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
