1. A mobile communication device comprising:
- a first member having a user interface;
a second member; and
a linkage mechanism coupling the first member and the second member such that the device has a closed position and an opened position, the linkage mechanism comprising an expandable multi-pivot hinge, whereinin the closed position, the user interface is inaccessible,in the opened position, the user interface is accessible and a portion of the first member overlaps the second member,the expandable multi-pivot hinge comprises a first hinge piece and a second hinge piece,the first hinge piece is pivotably coupled to the first member via a first pivot and to the second hinge piece via a second pivot,the second hinge piece is pivotably coupled to the second member via a third pivot, such that the first hinge piece and the second hinge piece can rotate with respect to each other to allow expansion of the multi-pivot hinge, anda combined distance between the first pivot and the second pivot and between the second pivot and the third pivot is greater than a distance between the first pivot and the third pivot when the device is in either the opened position or the closed position.

Abstract
A mobile communication device and linkage mechanism are provided to enable an opened position of the device which is less than the total length of the lid and base members. In the opened position, a portion of the lid member overlaps the base member. The linkage mechanism may actuate translational movement of the lid member as the device is moved between the closed and opened positions.

1. A mobile communication device comprising:
-
a first member having a user interface; a second member; and a linkage mechanism coupling the first member and the second member such that the device has a closed position and an opened position, the linkage mechanism comprising an expandable multi-pivot hinge, wherein in the closed position, the user interface is inaccessible, in the opened position, the user interface is accessible and a portion of the first member overlaps the second member, the expandable multi-pivot hinge comprises a first hinge piece and a second hinge piece, the first hinge piece is pivotably coupled to the first member via a first pivot and to the second hinge piece via a second pivot, the second hinge piece is pivotably coupled to the second member via a third pivot, such that the first hinge piece and the second hinge piece can rotate with respect to each other to allow expansion of the multi-pivot hinge, and a combined distance between the first pivot and the second pivot and between the second pivot and the third pivot is greater than a distance between the first pivot and the third pivot when the device is in either the opened position or the closed position. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A mobile communication device comprising:
-
a first member having a user interface; a second member; a linked end; and a linkage mechanism coupling the first member and the second member near the linked end such that the device has a closed position and an opened position, the linkage mechanism comprising; a first gear fixedly coupled to the first member; a second gear fixedly coupled to the second member; and a third gear meshed with each of the first and second gears to transfer rotation therebetween, wherein in the closed position, the user interface is inaccessible, and in the opened position, the user interface is accessible and a portion of the first member overlaps the second member, and as the device is moved from the closed position to the open position, the first member rotates with respect to the second member, said rotation being transferred to the third gear via the first gear and causing the third gear to travel around a circumference of the second gear in a direction away from the linked end. - View Dependent Claims (12)

13. A mobile communication device comprising:
-
a first member having a user interface;
a second member;a linked end; and a linkage mechanism coupling the first member and the second member near the linked end such that the device has a closed position and an opened position, the linkage mechanism comprising; a first link having a first end, a second end, and a recess, the first link being pivotably connected, at the first end of the first link, to the first member by a first pivot and pivotably connected, at the second end of the first link, to the second member by a second pivot; a second link having a first end, a second end, and a recess, the second link being pivotably connected, at the first end of the second link, to the first member by a third pivot and pivotably connected, at the second end of the second link, to the second member by a fourth pivot, wherein the second and fourth pivots are disposed a first distance apart lengthwise on the second member, the first and third pivots are disposed a second, shorter, distance apart on the first member, in the closed position;
the user interface is inaccessible;
the second link is nearer to the linked end than the first link;
the first pivot of the first link is nearer to the second member than the third pivot of the second link; and
the first end of the first link is received in the recess of the second link, andin the opened position;
the user interface is accessible;
the third pivot of the second link is nearer to the second member than the first pivot of the first link; and
the first end of the second link is received in the recess of the first link and a portion of the first member overlaps the second member. - View Dependent Claims (14)

15. A linkage mechanism for rotatably coupling a first member and a second member of a mobile communication device, at a linked end of the communication device, such that the device has an opened position and a closed position, comprising:
-
a first gear fixedly coupled to the first member; a second gear fixedly coupled to the second member; a third gear meshed with each of the first and second gears to transfer rotation therebetween, wherein in the closed position, a user interface of the first member is inaccessible and in the opened position, the user interface is accessible and a portion of the first member overlaps the second member, the linkage mechanism actuates translational movement of the first member for at least part of movement of the device from the closed position to the opened position and at least part of movement of the device from the opened position to the closed position, and as the device is moved from the closed position to the open position, the first member rotates with respect to the second member, said rotation being transferred to the third gear via the first gear and causing the third gear to travel around a circumference of the second gear in a direction away from the linked end.
