1. A hinge for a mobile communications terminal comprising a first and a second section, said hinge comprising:
- a hinge frame;
a first hinge pin fixed to said first section and mounted for rotation on said hinge frame, said first hinge pin defining a first axis of rotation with the first section;
a second hinge pin fixed to said second section and mounted for rotation on said hinge frame, said second hinge pin defining a second axis of rotation with the second section, offset from said first axis of rotation, wherein each of the first and second hinge pins is constructed having one conical or truncated conical gear connected thereto; and
a third hinge pin mounted on said frame for rotation about a third axis of rotation transverse to said first and second axes of rotation, said third hinge pin having two conical or truncated conical gears connected thereto, said conical or truncated conical gears of said third hinge pin being coupled to the conical or truncated conical gears of the first and second hinge pins so that rotational movement of the first hinge pin is synchronized to the second hinge pin via the coupled conical or truncated conical gears of the third hinge pin.

Abstract
A mobile communications terminal including a first section having a keypad; a second section having a display; and a connection movably connecting the second section with the first section. The connection includes a first axis of rotation with the first section, an offset second axis of rotation with the second section, and synchronizing members which transfer rotational movement of the first section relative to the connection to rotational movement of the second section relative to the connection.

5. A hinge comprising:
-
a hinge frame; a first hinge pin mounted for rotation on said hinge frame, said first hinge pin defining a first axis of rotation, with a first element connected to the hinge; a second hinge pin mounted for rotation on said hinge frame, said second hinge pin defining a second axis of rotation offset from said first axis of rotation, with a second element connected to the hinge; and wherein each of the first and second hinge pins are constructed having one conical or truncated conical gear connected thereto; a third, hinge pin mounted on said frame for rotation about a third axis of rotation transverse to said first and second axes of rotation, said third hinge pin having two conical or truncated conical gears connected thereto, said conical or truncated conical gears of said third hinge pin being coupled to the conical or truncated conical gears of the first and second hinge pins so that rotational movement of the first hinge pin is transferred to the second hinge pin via the coupled conical or truncated conical gears of said third hinge pin to synchronize the relative movement of the first and second elements. - View Dependent Claims (6, 7)

8. A mobile communications device comprising:
-
a housing; a transceiver in the housing; a keypad connected to the housing; and a display connected to the housing; wherein the housing comprises a first section movably connected to a second section of the housing by a multi-axis hinge, wherein the multi-axis hinge further comprises; a hinge frame; a first hinge pin mounted for rotation on said hinge frame, said first hinge pin defining a first axis of rotation, with a first element connected to the hinge; a second hinge pin mounted for rotation on said hinge frame, said second hinge pin defining a second axis of rotation offset from said first axis of rotation, with a second element connected to the hinge, wherein each of the first and second hinge pins are constructed having one conical or truncated conical gear connected thereto; a third, hinge pin mounted on said frame for rotation about a third axis of rotation transverse to said first and second axes of rotation, said third hinge pin having two conical or truncated conical gears connected thereto, said conical or truncated conical gears of said third hinge pin being coupled to the conical or truncated conical gears of the first and second hinge pins so that rotational movement of the first hinge pin is transferred to the second hinge pin via the coupled conical or truncated conical gears of the third hinge pin to synchronize the relative movement of the first and second elements. - View Dependent Claims (9, 10, 11)
