SAFETY DEVICE FOR SCROLLING DOOR

Field of the invention

The present invention relates to a safety device for scrolling door,

the scrolling door is able to be opened in emergent situations.

Background Art Discussion

The conventional scrolling doors are used for business sites and

can be opened and closed by motors. When the electrical power cannot be

normally supplied, the users are difficult to manually open the scrolling

doors due to the brake function of the motors. In some emergent situations,

the scrolling doors with fail motors may impede evacuation and cause

people injuries.

Some of the scrolling doors are cooperated with a clutch which

can switch the electrical operation mode into the manual operation mode, so

that when in emergent situations, the users can switch to the manual

operation mode and successfully open the scrolling doors. However, the

clutch usually is installed to either an indoor position or an outdoor position, that is to say, only the people who can access the clutch can switch the electrical operation mode into the manual operation mode.

A latest safety device is installed to the wall and allows the users

to open the scrolling door either from outside or inside positions. However,

the safety device has to drill a hole through the wall, and this needs to be

further improved.

The present invention intends to provide a safety device for a

scrolling door, and which improves the shortcomings of the conventional

safety devices.
