DESCRIPTION:
BRIEF SUMMARY
The invention relates to a warning sign, substantially triangular in shape and provided with a supporting foot as disclosed in the preamble to claim 1.
A sign of such a type is used in traffic, and must be carried by motor vehicles so that in the event of breakdown or accident with the vehicle, it can be positioned behind the vehicle in order to avoid other vehicles running into the stationary vehicle.
However, the known signs have the disadvantage that they are visible from only one side. If an accident has occurred at a place in which the traffic is coming from several sides, the sign is not visible from some of the sides. Moreover, it is desirable to be able to mark the place more clearly in the dark, in that reflections from wet road surfaces, street lights etc. will often make the sign easy to overlook.
The object of the invention is to present a warning sign which can be seen more easily from several sides in a relatively simple manner.
This is achieved by making the signpost rotatable in the foot, and by making the actual sign plane and providing the two side edges facing away from the post with two flanges which extend mutually opposite in relation to the main plane of the sign. The main plane is one which is parallel with the sign surface or surfaces which bear the warning symbol or the warning information.
The sign can thus rotate under the influence of the wind, which in daylight means that the sign is presented to all sides, and in the dark that a flashing effect is produced by reflection of the light from a vehicle in the warning colours and/or the sign's reflective coating, which makes the sign considerably easier to see.
A simple and advantageous embodiment from the production point of view is disclosed in claim 2.
By providing the foot with a magnet, the sign can, for example, be secured on the roof of a car, which can be of great significance for the sign's visibility when there is snow along the roadside or other obstructions which prevent it from being seen along the ground.
In order to avoid the costs of a ball bearing, and to make production cheaper, it is preferred that the sign be configured as disclosed in claim 4, where the connection between the post and the foot is in the form of a snap connection on the end of the post, which can enter into engagement with an annular groove in the foot.
Examples of embodiments of the invention will now be described in more detail with reference to the drawing, where
FIG. 1 shows a first embodiment of the warning sign according to the invention in the form of a warning triangle seen at right-angles to the main plane of the sign,
FIG. 2 shows the same as in FIG. 1, but parallel with the main plane and from the side,
FIG. 3 shows a section along the line III--III in FIG. 1,
FIG. 4 shows a cross-section through the foot of the warning sign,
FIG. 5 shows an exploded drawing of a second embodiment of the invention, and
FIG. 6 shows an enlarged detail section of the foot of the second embodiment in the assembled condition.
The warning triangle consists of a sign 1, a foot 2 and a shaft or holder 3.
The actual sign 1 can be built-up of laminated or injection-moulded synthetic material, and on both sides be provided with reflective foil in colours, so that a red triangle with white centre part is formed. Along two of the side edges 4 of the sign 1 there are bent flanges 5 which extend at an angle in relation to the main plane of the sign 1, in that the flanges 5 face in opposite directions in relation to the main plane. The angle in relation to the main plane is 45 degrees, but other angles can naturally be selected within the scope of the patent claims. Moreover, the flanges 5 do not need to be plane or straight as shown in FIG. 3, but can consist of curved pieces.
At a third side edge of the sign 1 there is secured a shaft or holder 3 which, in the preferred embodiment, consists of a cylindrical piece of synthetic material. The holder 3 is housed in a rotatable manner in a ball bearing 7 in the foot, in that the holder 3 is secured to the inner ring of
