Abstract

Disclosed is a panel latch mechanism which can be operated with one hand when the user opens the LCD panel of notebook PC. Notebook PC that has two latches on the panel both sides of front left and right (Figure 1) needs to be operated each latch knob at the same time when the user opens the LCD panel. This means that this method requires the user with both hands. Our new method makes an offer the easy of use latch system to our customers. This method is very simple, low cost, reliable and easy of use, and does not require our users to operate the latch knob at the same time with both hands. Figure 2 to 6 show the detail mechanism of this method. When the user operates the latch knob to open the panel, the latch will be locked by the latch stopper at the released position (Figure 6) and does not return to initial position (normal position) that is shown as Figure 5 unless otherwise open the panel. Therefore user is not required to operate both left and right latch knobs with both hands at the same time but be able to operate them by sequential operation with one hand. After opening the panel, the locked latches (shown in the Figure 6) will be set free for next operation automatically, because the latch on the panel and latch stopper on the system will be separated each other by opening the panel.

One Hand Latch System for Notebook PC

    Disclosed is a panel latch mechanism which can be operated with one hand
when the user opens
the LCD panel of notebook PC.

    Notebook PC that has two latches on the panel both sides of front left
and right (Figure 1) needs
to be operated each latch knob at the same time when the user opens the LCD
panel. This means
that this method requires the user with both hands. Our new method makes an
offer the easy of
use latch system to our customers. This method is very simple, low cost,
reliable and easy of use,
and does not require our users to operate the latch knob at the same time with
both hands.

    Figure 2 to 6 show the detail mechanism of this method. When the user
operates the latch knob
to open the panel, the latch will be locked by the latch stopper at the
released position (Figure 6)
and does not return to initial position (normal position) that is shown as
Figure 5 unless otherwise
open the panel. Therefore user is not required to operate both left and right
latch knobs with both
hands at the same time but be able to operate them by sequential operation
with one hand.

    After opening the panel, the locked latches (shown in the Figure 6) will
be set free for next
operation automatically, because the latch on the panel and latch stopper on
the system will be
separated each other by opening the panel.
