Description

DK 97 00126 U3

designation:

Electrically operated roof sign for trucks.

Field of application:

This provision relates to an electrically operated roof sign for trucks which opens the possibility of changing the text on the sign by means of a latch control.

Prior Art:

Standard roof signs / light boxes where the text can only be changed by physically exchanging printed acrylic sheets.

The technical problem to be solved: On the known roof signs you can only replace the text by replacing the entire front of the sign, which means that you have the necessary texts / fronts available at the time of replacement, while at the same time it is necessary and time-consuming to have to up on the roof of the truck.

The new technique:

The new feature of this sign is that it works by the principle of the conveyor belt, which means that the sign is equipped with a mechanism capable of carrying a pre-printed conveyor belt with up to 50 names or logos back and forth between two main rollers.

The sign on the front is provided with a window that the roller conveyor passes as it travels back and forth between the two main rollers.

This way, you can display the desired text in the window by stopping the tape in the right place.

Technical impact:

You can change text on the truck anywhere and at any time it is needed without wasting time for neither truck nor driver.

The sign and its functions are explained in detail below with reference to the attached drawing.
