Definitions

the present invention refers to a pole or part of a pole for marking road curbs, which pole after collision is self restoring and consists of a tubular profile with a closed hollow cross section, designed as an isosceles triangle with sides and a base.
Poles supporting reflectors or other road signs by the curb of roads are means to enhance the traffic security and improve the visual guidance, especially at night driving.
Poles manufactured in plastic materials with a tubular closed cross section has poor elastic properties and by collision get consisting bending damages and fractural impressions, unless the pole breaks off completely.
the pole i.a. should consist of a hollow closed cross section profile, usually with triangular form.
a verge pole for example should have a life-span of between five and ten years and be able to withstand various stresses which are caused by the wind, by cleaning equipment and by snow that has been ploughed towards the curbe of a road.
US-A-4596489 discloses a road marking pole which is manufactured as a plastic profile which makes it self restoring after bending.
This known pole has a mainly rectangular cross-section with two broad long sides.
the shape and the fact that the pole is provided with a number of longitudinal relief grooves at points of deformation, renders it a low bending stiffness and therefore it bends with a radious along a rather long section. This leads to the pole being influenced even by moderate gusts and can be bent downwards out of sight, when it is hit by ploughed snow.
the purpose of the present invention is to provide a pole consisting of a hollow profile which is closed in cross section, which is rigid at bending and which does not bend down until exceeding a predetermined transversal force, for example by collision and stands bending approximately 90 degrees repeated times without permanent deformations.
the pole shall be able to be manufactured with simple and cheap manufacturing methods, for example by extruding of an impact resistant plastic material.
the hollow profile being constituted by a homogenous, unbroken limiting wall, and that the base includes two essentially equally long, straight wall sections, which meet each other at an angle which is larger than the angle between the two sides.
Fig. 1 shows a first embodiment of a pole 10 according to the invention, as to its external appearance very little differs from road marking poles according to for example German standards.
the pole 10 is provided with a day mark 11 which also carries reflecting devices 12, which are shaped with a rectangular and two circular areas respectively depending on which side of the pole 10 being directed against the driving direction.
the pole 10 shown in Fig. 1 is constituted by a closed hollow profile, shown in Fig. 2, with a homogenous, unbroken limiting wall 13 which lacks both inner stiffening means and longitudinal relief grooves.
This wall 13 includes four essentially straight wall portions 14-17, of which the two first-mentioned are approximately twice as long as the latter.
the cross-section profile of the poles can be surrounded by an isosceles triangle with rounded corners, where the height is bigger than the base.
the two longer wall sections 14, 15 in the cross section of the pole is connected by means of a circular arc section 18 which fixes said wall portions at a certain angle.
the two shorter wall sections 16, 17 are mutually connected via a blunt angle section 19 which has a considerably smaller extension than the arc section 18.
An angle between the wall sections 14, 15 is considerably smaller than an angle between the wall sections 16, 17.
the arc shaped portion 18 has a larger radius than the rest of the interconnection portions 19-21 between the straight wall portions 14-17.
the straight wall portions of the pole and the angles and the radii between these accomplish that the hollow profile can be pressed together, such as illustrated by fig. 3.
the pole can be folded to one or the other side, without need for any appreciable force to be applied.
the triangular shape of the pole thus makes it initially stiff, but after compressing to the state shown in Fig. 3, the pole is yielding versus transversal load.
the pole strives to restore itself to its original hollow form, which means that the pole immediately again is straightened up.
Fig. 4 is illustrated how a known pole with closed hole profile is permanently deformed.
Fig. 5 shows corresponding folding section for the pole according to the invention according to fig. 1 - 3. As is illustrated by Fig. 5 the folding is controlled, without crumpling together the wall portions, so that the pole after the folding again can be restored. From fig. 5 it can be seen that the folding of the pole occurs locally on a very short part of its length.
Fig. 2 illustrates that the day mark 11 is shaped as a sleeve with the same hollow profile as that of the pole, but with slightly larger measure.
the sleeve can be widened by flattening out the angle between both shorter wall sections, whereupon the sleeve can be slided onto the pole and be displaced along this to correct position.
the angle between both shorter wall sections again is allowed to spring back a clamp joint is obtained between the sleeve and pole.
the sleeve can finally be fixed to the pole by means of screws for attachment of the reflectors 12.
the pole according to the invention preferably can be manufactured through extruding or injection moulding of an impact resistant, UV-stabilized polypropene plastic material, which can be recycled.
arc section 18 can be flattened.
