Hinge device for a portable computer
First Claim
1. A hinge device comprising:
- a first shaft attached to a first chassis, wherein said first shaft includes a recess located on an outer peripheral surface of said first shaft;
a second shaft attached to a second chassis, wherein said second shaft includes a recess located on an outer peripheral surface of said second shaft;
a lock member includinga first projection engageable with said first recess;
a second projection engageable with said second recess; and
an arm member coupling said first projection and said second projection to each other, being swayable by supporting a portion of said arm member between said first projection and said second projection by a rotation shaft, and disposed at a side of said first shaft and said second shaft that are disposed side by side,wherein said lock member allows rotation of one of said first shaft or said second shaft and restricts rotation of said each other in accordance with an opening/closing angle position between said first chassis and said second chassis by alternately performing engagement of said first projection with said first recess and engagement of said second projection with said second recess by means of sway of said arm member.

Abstract
A hinge device capable of reducing a reduced-size biaxial structure that can selectively switch rotations of two shafts according to an opening/closing angle position between two chassis is disclosed. The hinge device includes a first shaft attached to a first chassis, and a second shaft attached to a second chassis. The first shaft includes a recess located on an outer peripheral surface of the first shaft, and the second shaft includes a recess located on an outer peripheral surface of the second shaft. The hinge device also includes a lock member having a first projection engageable the said first recess, a second projection engageable with the second recess, and an arm member coupling the first projection to the second projection. The lock member allows rotation of one of the first shaft or the second shaft and restricts rotation of each other according to an opening/closing angle position between the first chassis and the second chassis by alternately performing engagement of the first projection with said first recess and engagement of the second projection with the second recess by means of sway of the arm member.
