DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a road sign and information display apparatus.
Setting up as well as changing road signs and information displays made from metal sheeting is laborious, which is a large drawback in the temporary use of signs, or changes of them, as well as setting up other information messages of temporary nature for road users.
The object of the present invention is to achieve a road sign and/or information display apparatus which can be rapidly and easily placed in position and removed.
This object is achieved with a road sign and information display apparatus in accordance with claim 1.
In providing signs for road works, for example, the road sign message may be readily unrolled, and after termination of the work period once again wound up on its roller. In this way the road sign or information display is protected from becoming dirty, so that it will remain just as clean the next time it is used as it was when it was rolled up. A road sign in accordance with the prior art that has been opened out during a weekend, for example, is however dirtier the next time it is to be used, and may also be covered with snow and ice, if the weather conditions are such.
Temporarily covering and uncovering signs is also a large and expensive task, which is considerably simplified by the inventive apparatus. Since the road sign and information display apparatus can be placed close to a road sign displaying an erroneous message, the screen with the correct information can obscure the former when the screen is rolled out.
In accordance with an advantageous further development of the apparatus in accordance with the invention, the stand carrying the roller is formed such as to be carried by a car or other vehicle, by special a trailer or as to also be stationarily installed. The stand can thus be formed for mounting on an ordinary car roof rack, and by unrolling the screen road users are warned in a simple manner of conditions such as road works in progress and/or informed what side of the vehicle they shall pass. Further, if the roller is motor driven and adapted for operation from inside the vehicle, the screen can be rolled out while the vehicle is moving, i. e. road users can be informed before the working vehicle has stopped. To advantage, the stand can also be formed for mounting on the tailgate of a lorry, a special road sign carrier then not being needed. However, if a special carrier is used, it can be made much less voluminous for the road sign and information display apparatus according to the invention than a conventional road sign carrier. On the same area as required for a conventional carrier, there is room for four cassette trailers made for the apparatus according to the invention, e. g. when they are placed on a lorry deck for transport.
According to a further advantageous embodiment of the apparatus according to the invention, the stand is collapsible, preferably by making it with spring biased folding arms or telescopic arms for correctly unrolling the screen carrying the display. Transport of the road sign or information display apparatus is facilitated by such collapsibility.
If a motor driven roller is used, this can be remotedly controlled in another advantageous embodiment of the apparatus according to the invention, thus enabling a temporary message to be displayed without somebody having to visit the site of the apparatus to operate it. If the message is to be displayed at regular intervals during the day, for example for a certain time of the day, this can be controlled automatically with the aid of e. g. a computer.
According to a still further advantageous embodiment of the apparatus according to the invention, the road sign and information message is arranged on soft, reflective plastics material attached to a net fabric. There is thus obtained visibility through the screen at the sides of the actual displayed information, which is an important advantage from the traffic safety aspect and in addition air can pass through the net, i.e. wind effect on the apparatus will be redu
