Definitions

• the present invention relates to improvements in limit marking units of the kind having holes for connecting and/or anchoring elements serving for interconnecting units or for anchoring a unit or units to a base.
• each unit comprises at least one reinforcement member which extends from one hole for a connecting and/or anchoring element to another and surrounds these holes.
• the reinforcement member constitutes a very forceful reinforcement for the separate unit, even if the latter in itself should consist of a comparatively fragile material.
• the reinforcement member forms a link in a chain of interconnected links which can be anchored and which chain will form automatically upon interconnecting a plurality of units. After interconnection, the units cannot get separated when subjected to normally occurring actions, and the units cannot either get tilted if subjected to normally occurring strains, since they support each other in an advantageous way and, in addition, may be anchored to the base.
• Fig. 1 in a side-view illustrates a traffic limit marking unit according to the invention
• Fig. 2 is a plan view of the traffic limit marking unit
• Fig. 3 is a front view of the traffic limit marking unit
• Fig. 4 in a side view illustrates two different interconnected traffic limit marking units according to the invention.
• Fig. 5 illustrates a number of inventive traffic limit marking units interconnected into a limit marking barrier which is provided with marking and separation poles.
• the traffic limit marking units 1, 2 illustrated preferably consist of a casting compound for instance of concrete material.
• the units 1, 2 are elongated in shape, for instance, and comprise, as seen in side view, a central portion la, 2a of uniform height and the top surface 1b, 2b of which is substantially plane.
• the unit 1 has an end portion 1c which is tapering in height in the direction away from the central portion, i.e. its top surface Id is sloping towards its outer end.
• the unit 1 has a second end portion le which at its top projects from the central portion la and forms a bottom face If to which another unit 1 can be connected with its top surface Id.
• the unit 2, on the contrary, has two uniform end portions 2c decreasing in height from the central portion 2a, i.e. their top surfaces 2d are sloping downward towards the end.
• Each unit 1, 2 is provided with a plurality of holes for instance three through-holes or partially through-going holes lg, 2e for receiving marking poles 3, separating poles 4, a combination of such poles or poles (not shown) of any other type.
• the end portions 1c, 1e and 2c are provided with through-holes 1h, 2f for connecting and/or anchoring elements 5 for interconnecting units 1 and/or 2 and/or for anchoring units 1 and/or 2 to a base 6.
• each unit 1 and 2 which reinforcement enables protection of associated connecting and/or anchoring elements 5 and poles 3 and/or 4, and which reinforcement, in addition, enables the formation of a forceful chain
• the links of which are rigidly interconnected when units 1 and/or 2 are interconnected at least one reinforcement member 7 is so shaped and arranged as to, as seen from above, surround an area containing all holes 1h and 1g and 2f and 2e, respectively.
• the latter could suitably be endless in shape.
• the effect of strains acting through member 5 or poles 3, 4 in the unit 1, 2 or through unit 1 , 2 on member 5 are effectively reduced by the fact that the reinforcement member 7 follows portion of the periphery of each hole lh, 2f for the extension of the connection and/or anchoring members 5 in the peripheral portion or immediately adjacent the latter, and extends past the hole or holes 1g, 2e for the marking and/or delimitation pole or poles 3, 4 so as to pass tangentiolly to this or these holes lg, 2e or immediately adjacent thereto.
• the reinforce ment member 7 will carry said strains very effectively, thus reducing the danger of breaking the cast material.
• the reinforcement member 7 may, as seen in side view, extend substantially parallel with the top surface 1b, 2b of the central portion 1a, 2a and deviate downward at its end portions 1c, 2c with decreasing height, extending substantially in parallel to the top surface 1d, 2d of the end portion 1c, 2c to the hole 1h, 2f for the connecting and/or anchoring element 5.
• a portion of the reinforcement-element-portion extending in parallel with the top surface 1b of the central portion 1a may extend into a projecting end portion 1e of the traffic separation unit 1, said end portion 1e being provided with a hole 1h for the connection and/or anchoring element 5.
• the reinforcement member 7 may - as seen from aside - pass through the holes lh, 2f for the connecting and anchoring elements 5 about halfway between the end portions of the holes 1h, 2f and the holes 1g, 2e for the marking and/or limit poles 3, 4 adjacent to the upper end portions of these holes 1g, 2f.
• the reinforcement member 7 will be particularly strong if it has its two longer sides 7a, 7b extending in parallel relation, and if one or more or all the holes comprise eyelets (not shown), these eyelets are suitably rigidly anchored to the reinforcement member 7 in order to increase the strength of the unit.
• the reinforcement member 7 may be penetrated at a point without such penetration, in certain cases, constituting any serious disadvantages, the reinforcement member 7 may be disposed completely or in part outside the body of the unit, more than one reinforcement member 7 may be present, and the reinforcement member 7 may follow the peripheries of one or more holes to a larger extent than as shown in the drawings.
• the holes 3, 4 may carry road or traffic signs, function as fence paling, marking poles or they can carry other kinds of elements for traffic guiding purposes.
• the connecting and anchoring member 5 may carry a sleeve (not shown) of elastic material next to its head. This may be compressible and should serve, inter alia, as a gripping member for a pair of tongs for extracting the member 5.
• the latter can be made short in order solely to serve as a connection member, or long in order to serve as a connecting and anchoring element.
• the holes 1g, 2e for the poles 3, 4 may be wider at their upper than at their lower ends in order to allow a certain amount of movement of the poles 3, 4 which can be passed through the units and be secured in place by a locking device (for instance a padlock) disposed beneath the unit. Poles locked in this way may carry parking meters.
• the holes lg, 2e may be provided with a bottom element which closes the bottom end of the hole completely or in part.
• This bottom element should be thin enough to enable the same to be broken by means of a pole 3, 4 when necessary.
• sleeves of elastic material may be advantageous in certain cases to dispose sleeves of elastic material within one, several or all the holes so as to give a resilient support for the poles 3, 4 and/or members 5. The last-mentioned arrangement, however, has not been shown since it has no direct relation to the inventive principles.
