The lock is difficult to set, cannot be released smoothly,
and cannot be stopped at the desired position. When the
screen is fully pulled down, it resists movement. |
 |
|
| 2. |
The screen winds up all at once, and reaches the end
with a noisy impact. The impact with the storage case
can lead to screen damage. |
 |
|
|
 |
| 1. |
The screen stops immediately even when pulled down lightly.
The release is also smooth, and the screen easily winds
up after being fully extended. |
 |
|
| 2. |
The screen slowly winds up like a motorized screen,
and stores quietly. There is no damaging impact when the
screen is fully wound up. |

When the screen is pulled out, the switching ball just goes
around along the guide groove in the direction indicated by
the arrow in Figure 1. Thus the screen can be pulled out smoothly.
|
| 2. |
When the screen is released in any position, the switching
ball moves in the direction indicated by the arrow in Figure
2 and stops at the fixed locking part.
|
| 3. |
When the screen is pulled out again, the switching ball goes
to the temporary locking part as shown in Figure 3-(1) and turns
around with the ball guide.
|
| 4. |
When the screen is released, the switching ball goes to the
position as shown in Figure 3-(2) and starts going around along
the guide groove in the direction indicated by the arrow. This
way the screen can be wound up completely and stored easily.
|
| 5. |
When the screen is pulled out again, the switching ball in
the position as shown in Figure 3-(2) goes around in the direction
indicated by the arrow in Figure 1 through the return groove
as shown in Figure 3-(3). (Steps 1 to 3 are repeated.)

 |
| 1. |
When the screen is pulled out, the built-in spring clutch
(1) is disengaged and the housing (2) runs idle. Thus the screen
can be pulled out smoothly.
|
| 2. |
When the screen is wound up, the take-up roller rotates under
the spring force, the spring clutch (1) is engaged, and the
housing (2) rotates together with the roller.
|
| 3. |
When the housing (2) rotates, it allows the governor (5) to
rotate at a high speed through the planet gear (4). The governor
extends centrifugally and rubs against the inner surface of
the housing. Then the rotation of the take-up roller (3) is
decelerated to wind the screen up slowly.
