Biaxial Hinge
First Claim
1. A biaxial hinge comprising a first hinge shaft attached to the side of a first casing and a second hinge shaft attached to the side of a second casing, said first hinge shaft and said second hinge shaft being connected to each other via a joint member and provided so as to be rotatable relative to each other, and a selective rotation restricting means provided between said first hinge shaft and said second hinge shaft, wherein said selective rotation restricting means is so structured that it allows the both hinge shafts to rotate, when said first casing and said second casing are in a closed state, and it restricts one of said first hinge shaft and said second hinge shaft in rotation, when the other hinge shaft rotates relative to the one hinge shaft.

Abstract
To provide a biaxial hinge which enables an opening/closing movement of terminal, such as notebook PC, from 0° up to 180° or more, which ensures the opening/closing movement starting from a stable stopping position available at any opening/closing angle, a second hinge shaft attached to a second casing and a second hinge shaft attached to a second casing are connected to each other via a joint member and provided so as to be rotatable relative to each other, and a selective rotation restricting device is provided between the both hinge shafts. The selective rotation restricting device is so structured that it allows the both hinge shafts to rotate, when the first casing and the second casing are in a closed state, and it restricts one of the first hinge shaft and the second hinge shaft in rotation, when the other hinge shaft rotates relative to the one hinge shaft.

- 1. A biaxial hinge comprising a first hinge shaft attached to the side of a first casing and a second hinge shaft attached to the side of a second casing, said first hinge shaft and said second hinge shaft being connected to each other via a joint member and provided so as to be rotatable relative to each other, and a selective rotation restricting means provided between said first hinge shaft and said second hinge shaft, wherein said selective rotation restricting means is so structured that it allows the both hinge shafts to rotate, when said first casing and said second casing are in a closed state, and it restricts one of said first hinge shaft and said second hinge shaft in rotation, when the other hinge shaft rotates relative to the one hinge shaft.
- 3. A biaxial hinge comprising a first hinge shaft attached to the side of a first casing and a second hinge shaft attached to the side of a second casing, said first hinge shaft and said second hinge shaft being connected to each other via a joint member and provided so as to be rotatable relative to each other, and a selective rotation restricting means provided between said first hinge shaft and said second hinge shaft, wherein said selective rotation restricting means allows said second hinge shaft to rotate so that said second casing can be opened and closed, when said first casing and said second casing are in a closed state, as well as allows said first hinge shaft to rotate so that said first casing is openable/closable, when said second casing is opened at a predetermined opening angle relative to either first casing.

5. A biaxial hinge comprising a first hinge shaft to the side of a first casing and a second hinge shaft attached to the side of a second casing;
- a joint member rotatably connecting the hinge shafts to each other, said first hinge shaft and said second hinge shaft passing through said joint member respectively in an identical direction;
a slide guide member provided opposite to said joint member, said first hinge shaft and said second hinge shaft passing through said slide guide member;
a selective rotation restricting means provided between said slide guide member and said joint member, for selectively restricting rotation of said first hinge shaft and said second hinge shaft;
friction torque generating means provided on either one side of said selective rotation restricting means; and
a suction means provided on either other side of said selective rotation restricting means; and
a stopper means restricting a rotation angle of said first hinge shaft and said second hinge shaft. - View Dependent Claims (6, 7, 8)
