The invention relates to a guidance sign for road traffic, which consists of a board with oblique to the longitudinal edge of the panel is made of reflective stripes of color.

Guiding signs of this type are used to increase road safety, e.g. where there is a route Half of the street is closed at a construction site and a lane change has to take place. Most of the guiding signs were previously made of wood and were either painted with luminous paint and / or with rear emitters occupied. Apart from the fact that these guidelines are in the rough construction business, in particular have proven to be unsustainable during transport, storage and installation the disadvantage that the retroreflective effect is very small.

It has also become known to make sheets of elastic material, e.g. B. produce plastic and then insert diamond-shaped reflectors into grooves or rubber beads that run obliquely to the longitudinal edge. It is also known to embed individual reflective elements and hl malleable masses in this way to produce flares. The well-known idea of arranging reflectors on signs, is also already realized in such a way that letter-shaped retro-reflectors individually Signs are screwed so that they result in words.

These known designs have the disadvantage that their reflective effect at night or Fog is not enough, and additional lighting must be installed as a result. These lights require considerable effort and are also prone to failure, so that the The effectiveness of the warning device is not always guaranteed. In addition, the colored covering must such signs that are damaged due to rough use or weather conditions, often renewed.

The previously common barriers, beacons, guide barrels, traffic cones, etc., which are used for identification of the large number of construction sites used on roads have one to the side of the road sloping hatching in the signal colors red and white or black and yellow. For marking from the left Obstacles lying on the road must therefore be hatched from top left to bottom right Signs and for obstacles on the right, those with hatching from top right to bottom left be set up. That implies two types of expensive signs. Since there is also a directional guide with an arrow shaped in the direction of the prescribed Hatching showing the direction of travel be-Leitzeichen for road traffic

be necessary, so far a supply of such signs had to be created.

The invention is based on the object of providing permanent, maintenance-free and highly effective To create guiding signs, the direction and shape of which can be changed in a few simple steps and in which damaged parts can easily be replaced with new ones.

According to the invention, the object is achieved in that the color strips are made up of directly strung together, equal-sized, isosceles and right-angled reflector triangles of different sizes There are staining, the cathetuses of which run parallel to the edges of the table, and which are known per se Way are inserted interchangeably in corresponding guide strips of the panel.

The entire guideline consists of reflectors, which have a good reflection and largely are weatherproof. Due to the triangular design of the reflector elements different Coloring can be done in the manner of a modular system on the guide signs to the left and Hatchings sloping to the right, but also a wedge-shaped arrangement of the hatching through a simple modification are formed.

The panel can advantageously consist of a sheet metal frame with bevelled edges on both long sides or beading obtained guides are provided in which the retroreflective Elements can be inserted from at least one of the shorter sides. On a shorter side of the Sheet metal frame, a stop can be arranged around the inserted elements when arranged vertically to hold on to the blackboard.

In a particularly simple way, the holding means can consist of a There are U-shaped bent retaining plate, which extends in the longitudinal direction of the sheet metal socket. If the board is arranged vertically, it is placed on the stand by means of the U-shaped retaining plate postponed. For a horizontal arrangement

Claims (3)

Stands can be provided in the holding plate transversely to the longitudinal direction of the sheet metal mount through openings. In the drawing, the subject matter of the invention is shown in several exemplary embodiments. It shows Fi g. 1 a guide sign in a vertical arrangement, FIG. 2 shows a longer guide sign in a horizontal arrangement, FIG. 3 shows a cross section through a guide sign with its sheet metal socket on a larger scale according to a first embodiment, Guiding signs in a horizontal arrangement. The guiding symbols according to FIGS. 1 and 2 consist of the sheet metal mounts 1, which are held on stands 2 with a heavy iron foot or the like, and the reflective elements 3 inserted into the sheet metal mounts. The individual element 3 does not have its own mount. It is mirrored on the back. It has a square shape and is divided into a white retroreflective field 4 and a red retroreflective field 5 along a diagonal. Depending on the length of the sheet metal frames, several elements 3 are attached to one another to form a unit, so that the white field 4 of one element is followed by the white field of the next element and a red field 5 is followed by the red field of the next element. Through this arrangement, the diagonally offset bands characteristic of this type of guide sign are obtained in alternating red and white colors. It is preferably provided in the embodiment according to the invention to give the sheet metal frames such a length and to design them so that they can be set up vertically or horizontally as required. The sheet metal frames then have a uniform length and the same training and can be used for both applications. As the sheet metal frames 1 in FIGS. 3 and 4 show in more detail, they are provided on the long sides with edges or flanges 6, which form a guide and holder for the retroreflective elements 3 to be inserted. Advantageously, a stop (not shown) is arranged on a short side of the sheet metal frame, which stops the reflective elements from slipping out of the sheet metal frame, especially when the panel is arranged vertically. A U-shaped retaining plate 7, which extends in the longitudinal direction of the sheet metal socket, is attached to the rear of the sheet metal frame 1. With the help of this holding plate 7, the sheet metal socket can be placed on a stand 2, for example with a U-shaped cross section. For the horizontal arrangement on two stands 2 according to FIG. 5 openings 8 are made in the holding plate 7, which extend transversely to the longitudinal direction of the holding plate. The support of the sheet metal frame on the uprights is carried out here, for example, by a screw 9 inserted into each upright 2. However, the stand can also be angled in such a way that the sheet metal frame rests with its lower edge on the angled portion. If necessary, end pieces can be attached to the ends of the sheet metal frames to prevent unauthorized removal of the reflective elements. The material used for the sheet metal frame is primarily sheet iron or sheet aluminum. The reflective elements are made of plastic, for example. The invention makes it possible to easily replace damaged or destroyed parts of the guide sign. Patent claims: 1. Guide sign for road traffic, consisting of a board with an incline to the longitudinal edge reflective color stripes running along the board, characterized in that the color stripes are made up of directly equal-sized, isosceles and right-angled reflector triangles (4 and 5) of various colors, the cathetuses of which run parallel to the edges of the table and which are in In a manner known per se, inserted interchangeably in corresponding guide strips (6) of the panel are. 2. Guide sign according to claim 1, characterized in that the panel consists of a sheet metal socket (1) consists, on both long sides with obtained by folding or beading Guides (6) is provided in which the reflective elements (4 and 5) of at least one of the shorter sides can be pushed in. 3. Guide sign according to claims 1 and 2, characterized in that on a shorter one Side of the sheet metal frame (1) a stop is arranged. 4. Guide sign according to claims 1 to 3, characterized in that holding means for Fixing of the board are provided, consisting of an attached to the back of the board (1), U-shaped bent retaining plate (7) exist, which extends in the longitudinal direction of the panel. 5. Guide sign according to claim 4, characterized in that in the holding plate (7) transversely to In the longitudinal direction of the sheet metal mount, breakthroughs (8) are provided, with the aid of which the Board (1) can be pushed onto stand (2) in a horizontal position.
