Abstract

Disclosed is a mechanism for port replicator to provide warning to prevent detaching the device at illegal state. Rotating eject levers activates the eject mechanism and warning logic at different thresholds of its angle. With this difference, it is possible to provide the warning prior to start actual mechanical detachment.

Eject Warning or Port Replicator

      Disclosed is a mechanism for port replicator to provide warning
to prevent detaching the device at illegal state.  Rotating eject
levers activates the eject mechanism and warning logic at different
thresholds of its angle.  With this difference, it is possible to
provide the warning prior to start actual mechanical detachment.

      Port replicator (1) shown in Fig. 1 attaches Notebook PC (2)
using two hooks (3) at both sides which is working by rotating eject
levers (4).

      Eject warning mechanism consist of eject levers (5) in Fig. 2
which has an angle for mechanical ejection, Switch (6) to activates
warning logic and hooks (7) to fix the port replicator to notebook
PC.

      Fig. 3 shows the example of the operation for detachment and
mechanism to activate the warning.  Step 1 shows the initial state
where the system attaches to the notebook certainly.  At this step,
switch (6) is disabled and hooks are located at locked position.
Step 2 shows the second state where angle of the eject levers reaches
angle A (8).  At this step, eject lever activates the switch (6) for
warning by rotation and start warning if the system state is in a
illegal one for detachment.  However, hooks (7) still in a locked
position and eject lever does not start mechanical detachment.  When
the angle of the eject levers reaches angle B at step C, hooks (7)
moves to the unlock positions and eject levers starts the mechanical
detach...
