Definitions

• the present invention is related to an information
• signs and directive boards for the road users are set up along the roads. These signs and boards have to be set up close to the roads and should 10 be comparatively large, so that the road users easily can perceive the given information. Due to their position and their size the signs and boards are frequently exposed to heavy strains and loads, particularly in connection with snow-clearance work, especially snow-ploughing. Therefore, 15 it is highly desirable that the signs and boards are made very solid, so that expensive repairs and maintenance can be avoided as much as possible.
• the main object of the invention is to provide an information board which is more resistant than the signs and boards now in use and which is easy to transport and to set up. According to the invention, ' this object can be ob ⁇ tained by providing an information board having the charac ⁇ terizing features set forth in the claims.
• Figure 1 shows a perspective view, seen from behind, of a portion of an information board according to the in- vention.
• Figure 2 shows a side view of the board shown in Figu ⁇ re 1. Best Mode for Carrying Out the Invention
• the information board shown in Figures 1 and 2 compri- ses a plane sheet 10 the front of which is provided with the information to be given.
• the horizontal edges of the sheet are flanged to form two flanges 10a,10b projecting from the back of the plane sheet substantially perpendicu ⁇ larly to the plane of the sheet.
• These flanges are provided partly for stiffening the sheet and partly for attaching brackets 11,12 for fastening the plane sheet 10.
• the brack ⁇ ets 11,12 consist of angular assembling means attached to the flanges 10a,10b by means of rivets 13,14.
• Each bracket 11,12 is provided with a locking strap 15 and 16, respecti ⁇ vely.
• the locking straps are designed to surround a verti ⁇ cal post 17 to which the information sheet 10 is to be fas- tened, as clearly shown in Figure 2.
• the Figures only show one post 17, but normally two or more posts fixed in the ground are used for larger information boards.
• a profiled plate 18 is interposed between the plane sheet 10 and the post 17.
• This plate has substantially the same size as the plane sheet 10 and consists of a trapezoi ⁇ dal aluminium sheet having a number of parallel ridges 19 with plane top surfaces.
• the plane top surfaces of the rid ⁇ ges abut the back of the sheet 10 and have a height which is equal to or slightly larger than the width of the flang- es 10a, 10b, so that the profiled plate is rigidly braced between the sheet 10 and the post or posts 17, the profiled plate resting with its lower edge on the lower flange 10a of the plane sheet.
• the post or posts 17 will press the profiled plate 18 against the sheet 10, so that the profiled plate will support and stiffen the information sheet 10 over its whole area.
• the post or posts 17 are first erected by digging a hole in the ground for one end of each post and casting the end, if necessary.
• the information sheet is than loosely attached to the posts, and after that the profiled plate is pushed into the space between the information sheet and the post or posts. In this operation the lower edge of the profiled plate slides on the lower flange of the information sheet.
• the information sheet is than finally attached by tighte ⁇ ning the locking straps, and at the same time the profiled plate is squeezed between the sheet and the post or posts.
• the size of the profiled plate has been adjusted to the information sheet in advance. While only one embodiment of the information board according to the invention has been described and shown, it is evident that several modifications and variations are
• the information sheet for example, must not necessarily be rectangular, as shown in the Figures, but can have any shape. However, the rectangular shape is normally best suited. Furthermore, the sheet can have only a lower horizontal flange.
• the ridges of the profiled plates can have any other shape than the trapezoidal shape, for example be waved. To give the best effect, the ridges of the profiled plate should run sub ⁇ stantially perpendicularly to the carrying posts or bars, but the posts or bars may alternatively be positioned hori ⁇ zontally.
• the information sheet and the profiled plate can also be attached in many different ' ways.
