Abstract

Disclosed is an eject mechanism for a docking station or port replicator and notebook Personal Computer (PC). This mechanism enables movement of a slide hook (4) and an ejector (6) by one button (1) operation with difference in time. Then, the slide hook (4) is located in a guide post (3), giving a simple appearance and protection with the slide hook (4) (Fig. 6).

Eject Mechanism for Expansion Device/Notebook Personal Computer

      Disclosed is an eject mechanism for a docking station or port
replicator and notebook Personal Computer (PC).  This mechanism
enables movement of a slide hook (4) and an ejector (6) by one button
(1) operation with difference in time.  Then, the slide hook (4) is
located in a guide post (3), giving a simple appearance and
protection with the  slide hook (4) (Fig. 6).

Fig. 1 shows the structure of this mechanism.

In the case of docking, the opening of the PC is fitted to the guide
post (3) and pressed.  The slide hook (4) is usually tensed by a
spring (5), so that the PC is locked exactly with the docking station
(Fig. 2).  In the case of ejecting, the push button (1) has a
two-length boss.  The longer boss causes the slide hook (4) to move
forward, so that the PC is unlocked (Fig. 3).  After the slide hook
(4) is moved completely, the shorter boss presses the ejector (6) to
eject the PC (Figs. 4 and 5).  Then the spring (2) presses the push
button (1) to return to the initial position.

      Since this mechanism minimizes the space, cost, and eject
operation and causes a simple appearance, this can be applicable for
all docking eject mechanisms.
