Abstract
Abstract A radiotelephone (100) has a hinge (301) for joining a body (101) a cover (103) along an axis. The hinge (301) has a release and position mechanism (303) aligned along the axis that secures cover (103) in the closed position and releases cover (103) from the closed position. The hinge (301) further has an opening mechanism (305) that urges cover (103) from the closed position to the open position. The release and position mechanism (303) and the opening mechanism (305) secure cover (103) in the open position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
169 words
A wireless communication device having an open position and a closed position, the wireless communication device comprising: a cover provided with a first cavity; a body provided with a second cavity; a hinge joining the cover and the body along an axis, the hinge including, a leaf spring located in the second cavity and fixed to the body, the leaf spring having a bump; and a cam located the first cavity and the second cavity and rotatably fixed to the cover, the cam having a surface in rotatably slideable contact with the leaf spring and the second cavity, the cam further having a short lobe and a long lobe located on the surface; wherein the short lobe and the bump secure the cover in the closed position, and the long lobe and the bump hold the cover in the open position; and an opening mechanism aligned along the axis and in contact with the cover and the body, wherein the opening mechanism urges the cover from the closed position.
Claim 2
Dependent Claim
169 words
A wireless communication device having an open position and a closed position, the wireless communication device comprising: a cover provided with a first cavity; a body provided with a second cavity; a hinge joining the cover and the body along an axis, the hinge including, a leaf spring located in the second cavity and fixed to the body, the leaf spring having a bump; and a cam located the first cavity and the second cavity and rotatably fixed to the cover, the cam having a surface in rotatably slideable contact with the leaf spring and the second cavity, the cam further having a short lobe and a long lobe located on the surface; wherein the short lobe and the bump secure the cover in the closed position, and the long lobe and the bump hold the cover in the open position; and an opening mechanism aligned along the axis and in contact with the cover and the body, wherein the opening mechanism urges the cover from the closed position.
Claim 3
Dependent Claim
19 words
The wireless communication device of claim 1, wherein the opening mechanism further urges the cover to the open position.
Claim 4
Dependent Claim
24 words
The wireless communication device of claim 2, wherein the long lobe, the bump, and the opening mechanism secure the cover in the open position.
Claim 5
Dependent Claim
57 words
The wireless communication device of claim 1, wherein the opening mechanism comprises: a shaft rotatably fixed to the body; and means for urging the cover from the closed position, the means for urging the cover from the closed position having two ends, one end rotatably fixed to the body and another end rotatably fixed to the cover.
Claim 6
Dependent Claim
22 words
The wireless communication device of claim 4, wherein the means for urging the cover from the closed position is a torsional spring.
Claim 7
Dependent Claim
15 words
The wireless communication device of claim 1, wherein the wireless communication device is a radiotelephone.
Claim 8
Dependent Claim
229 words
A wireless communication device having an open position and a closed position, the wireless communication device comprising: a cover provided with a first cavity; a body provided with a second cavity; a hinge joining the cover and the body along an axis, the hinge including, a leaf spring located in the second cavity and fixed to the body, the leaf spring having a bump; and a cam located the first cavity and the second cavity and rotatably fixed to the cover, the cam having a surface in rotatably slideable contact with the leaf spring and the second cavity, the cam further having a short lobe and a long lobe located on the surface, wherein the cam is axially slideable in the first cavity and the second cavity; wherein the short lobe and the bump secure the cover in the closed position, and the long lobe and the bump hold the cover in the open position; means, located in the first cavity between the cam and the cover, for axially forcing the cam into the second cavity; and means, in contact with the cam, for axially forcing the cam away from the second cavity; wherein, when a user of the wireless communication device actuates the means for axially forcing the cam away from the second cavity, the short lobe clears the bump thus releasing the cover from the closed position.
Claim 9
Dependent Claim
229 words
A wireless communication device having an open position and a closed position, the wireless communication device comprising: a cover provided with a first cavity; a body provided with a second cavity; a hinge joining the cover and the body along an axis, the hinge including, a leaf spring located in the second cavity and fixed to the body, the leaf spring having a bump; and a cam located the first cavity and the second cavity and rotatably fixed to the cover, the cam having a surface in rotatably slideable contact with the leaf spring and the second cavity, the cam further having a short lobe and a long lobe located on the surface, wherein the cam is axially slideable in the first cavity and the second cavity; wherein the short lobe and the bump secure the cover in the closed position, and the long lobe and the bump hold the cover in the open position; means, located in the first cavity between the cam and the cover, for axially forcing the cam into the second cavity; and means, in contact with the cam, for axially forcing the cam away from the second cavity; wherein, when a user of the wireless communication device actuates the means for axially forcing the cam away from the second cavity, the short lobe clears the bump thus releasing the cover from the closed position.
