Abstract

When a notebook PC such as ThinkPad(R) notebook PC available from IBM, is attached to the Docking Station, only Hook moves and a motion is not transmitted to Eject Bar by devising the form of Cam. Since Link Mechanism does not need to move, the load for making Hook slide is mitigated sharply. Since Eject Bar->Hook is necessary to take into consideration ,the angle of Cam can be set as smaller than 45 degrees. Therefore, the load at the time of removal is mitigable. Moreover, in the case of Key Lock, Hook is fixable like a current type.

Eject Mechanism in Docking Station

Docking for a notebook PC is consisted as Fig.1.

If Eject Button is pushed, Link Bar is made to slide in the direction of A of Fig.2 through Link Mechanism, Hook is removed from Lower Case of the notebook PC, and Eject Bar is pushed out.

By forcing the notebook PC from a top, the hole for Hook of Lower Case of the notebook PC meets the slope of the head in Hook, and Hook slides in the direction C of Fig.2 temporarily.

In this case, when Hook escapes in the direction of C, Eject Bar is also slid in the direction of A along the slot on the Cam and Link Mechanism is also moved.

Since there is a motion of both Eject Bar->Hook and Hook->Eject Bar through Cam for attach and removal, the angle of Cam has been made into 45 degrees of neutrality. However, 45 degrees make load large in both of attachment and removal. It is not desirable.

Moreover, When Key is Locked, Eject Bar moves in the direction of B, and Hook can not move in the direction of C because of Cam shape.
