FI94789B - Foldable information panel - Google Patents

Abstract

The invention relates to a flexible traffic direction sign panel, which is made from plastic or similar material, and which flexes at the hinges 3. The hinges 3 are formed from the base material at the points where thinning grooves have been made. The flexible traffic direction sign panel resists impacts, corrosion and changes in weather conditions. <IMAGE>

Folding signboard

The invention relates to a folding signboard which is used at road junctions or the like to direct traffic in the right direction. The folding signboard comprises the actual sign and driving controls with arrow marks, as well as fastening means for attaching the sign to the desired location.

Traditionally, driving signs have been placed on booms running across lane 10. As the signs are located above the roadway, their placement must take into account the maximum permissible vehicle heights. Generally, such signs are made of metal plates and are rigidly attached to beams located above the carriageway 15. Because the signs are metal, it has been necessary to hang them high enough to prevent damage. However, the maximum permissible heights are violated in vehicles, and a collision with such a signboard may result. In this case, in addition to the signboard, the supporting beam and support structure can also be damaged. Such traditional metal-structured signboards are also susceptible to corrosion and will have to be replaced with new ones at regular intervals.

It is also known to have signboard arrangements in which the sign is hung on runes or the like. However, such structures have not gained much popularity because the effect of strong wind on such a suspended plate makes it difficult to read. In addition, in the event of a collision, there may be a metal hanging plate; 30 become unusable and cause damage to the vehicle.

The use of existing signboards, especially when several signs have to be superimposed, leads to high support structures, in which case the bar supporting the sign-35 has to be raised unnecessarily. Also, 2 94789 signs placed too high in terms of road safety are not in a favorable position in terms of the driver's field of vision. Even in bad weather, the signs at the top are poorly visible.

The folding signboard according to the invention improves traffic safety and facilitates the route selection of drivers. The folding signboard reduces the above drawbacks and is characterized by what is set forth in the following claims.

The advantage of the sign according to the invention can be considered to be the improvement of traffic safety. The signboard can be placed lower than conventional signboards, making it easier to detect in bad weather. In addition, the signboard fits better into the driver's 15 field of vision. Because the folding signboard is made of plastic or similar material, its service life is considerably longer than that of corresponding metal signs. The folding signboard can be folded for transport in a rather small and convenient size, with the different parts folding on top of each other. The marks are made of tape-like material or the like, in which case the new mark is made simply by replacing the new tape with the old one. The environmentally friendly folding signboard is good because the entire board is made of recyclable 25 material.

In the following, the invention will be explained in more detail with reference to the accompanying drawings.

In Figures 1-4, the number 1 refers to a folding signboard and the number 2 to the marks to be glued to the surface of the signboard 1. The number 3 is marked with a folding hinge and the mounting beam is marked with the number 4. The bolts or the like used for fastening 5 are marked with the number 5. The colliding vehicle is number 6. Hinge 3 is made by making grooves in the surfaces of the folding signboard on either side of the board. The grooves are marked with the number 7.

10 The folding signboard operates like a normal sign and is usually placed on the beam on the carriageway by bolts 5 or similar fastening means. The signboard according to the invention can, of course, also be used for purposes other than those described in this application. Thus, the board is suitable for use, for example, as a guide in industrial plants or for similar uses. The use of a folding signboard is of course also possible indoors, where its unbreakability and foldability provide 20 excellent additional benefits. Within the framework of the inventive idea, the folding signboard can be applied to quite extensive applications without falling outside the inventive idea.
