Definitions

  • This invention relates to an upright delineator of an impact resistant elongate web structure consisting of fibre reinforced synthetic material for driving into the ground.
  • Vehicle traffic control requires the use of road signs and markers as aids in solving the various problems associated with traffic safety and direction. It has been found that a useful characteristic for such signs and markers is that these posts have the ability to withstand vehicle impact, without requiring subsequent replacement. An attempt has been made to fill this need with various configurations of posts.
  • the structural design of such posts has involved the consideration of two opposing structural features, i.e. the elasticity required during dynamic conditions to permit the post to nondestructively bend with vehicle impact and the longitudinal rigidity required during static conditions to withstand forces resulting as the post is driven into a hard surface.
  • a post should also have sufficient elasticity that it will automatically assume its proper upright configuration after dissipation of any impact forces.
  • delineators are positioned in a hole or receptacle and are cemented or otherwise fixed in place with backfill. This process is both expensive and time-consuming. Further, it prolongs exposure of maintenance personnel to the danger of fast moving highway traffic. Wood and steel posts, to the contrary have driveability but lack flexibility to undergo impact.
  • Delineator devices which do have neither flexible nor driveable properties are disclosed in CH-A-376 139, DE-B-1 165 637, DE-U-7 213 603, DE-U-1 896 546, DE-A-2039298 and US-A-3 450 387. It is necessary for the installation of these delineator devices to either dig a hole in the ground or to provide a receptacle.
  • the rigid portion of the structure has customarily been made of strong materials which may dent or otherwise damage the impacting vehicle. Furthermore, the use of such rigid materials and springs and the assembly requirements result in excessive costs for the posts.
  • U.S. Patent No. 3,875,720 discloses a second approach to the problem, of providing elasticity in a post that can be driven.
  • a post is formed by a bundle of flexible rods that are clamped together to obtain the desired rigid property required during the static installation stage of the post. Deformation of the post during dynamic conditions is permitted by deflection of the various flexible rods away from the central axis of the post structure.
  • economic factors appear to have impeded utilization of such structure despite the growing need for such a post.
  • a fiberglass delineator (US-A-4 061 435) was developed which was capable of being driven at its top into the ground; however, flexibility was developed only after impact by a vehicle. Such impact caused a shearing-off of a rigid leg of the delineator leaving a very flexible upright section. This delineator was rejected by the industry due to its broken condition after impact with exposed fiber needles which represented a hazard to the public.
  • US-A-3 233 870 discloses a guard rail structure, which consists of resin impregnated glass fibre of a web-like structure wherein longitudinally extending fibres are enclosed within strips of transversely extending fibres.
  • the longitudinally extending fibres are forming strands having end projections beyond the guard rail.
  • the guard rail is mounted between a pair of upstanding horizontally spaced supports. Fastening means are provided on these supports engaging the projecting ends of the strands and maintaining the guard rail stretched therebetween.
  • the guard rail has high elasticity and energy absorption ability on impact and can readily be bent during installation. Long lengths of guard rail are necessary to absorb the energy of impact.
  • DE-A-2 121 347 discloses a delineator which purports to be moderately driveable in soft dirt; however, this delineator is formed of polyethylene which is thermoplastic whose elastic modulus is far below the range of thermosetting resins used in fiberglass compositions as described herein. Furthermore, soft dirt is seldom available for highway delineators in view of hard shoulder surface of typical road beds and a required penetration depth of up to 50 cm for the delineator. Therefore, the polyethylene delineator of DE-A-2 121 347 would be better classified as a flexible delineator which would require placement in a hole with cement or other form of backfill to permanently fix the delineator in position.
  • the present invention as characterized by the claims gives a solution for the task to provide a deformable post configuration having both longitudinally rigidity and bending elasticity to facilitate driving emplacement and subsequent impact without destructive deformation, and being producible at relatively low costs.
  • the invention provides an upright delineator consisting of a structure which does not damage a vehicle on impact and which can be manufactured within reasonable costs.
  • the delineator according to the invention comprises an elongated web and associated reinforcing structure.
  • the web portion of the delineator provides the flexible properties which permit bending of the delineator in response to a bending impact force.
  • the reinforcing structure is necessary to develop a high modulus of elasticity along the longitudinal axis of the delineator.
  • Such reinforcing structure is implemented by specific utilization of fiber orientation within the web structure.
  • a second form of stress anticipated for the delineator is the bending stress applied upon impact by a moving object with a surface of the delineator.
  • This form of stress arising during dynamic conditions, is represented by the following relationship: where:
  • the present invention involves unique structural design to establish a proper balance between E, the elastic modulus and I, the moment of inertia. Whereas large values of E are required to maintain the necessary rigidity to withstand the longitudinal driving force arising during static conditions of installation, I is of minimal value to improve the bending ability of the delineator to achieve a low radius of curvature.
  • the preferred delineator of the present invention also provides a variable EI response to the respective loading and bending stresses, to satisfy both static and dynamic conditions in a single embodiment.
  • an important preferred aspect of the present invention is the recognition that, under typical uses of a delineator, the value of EI in the static condition during installation will not fully satisfy the bending requirements experienced during impact at a lateral surface. Inherent properties within the delineator are required which will develop a lower EI product during dynamic bending. Simply stated, the most versatile delineator must respond to a driving load with a high EI product to preclude buckling, but must experience a lower EI during bending subsequent to impact.
  • Figure 1 illustrates the first embodiment of the delineator wherein the appropriate balance between E and I is obtained by a combination of geometrical structure and material composition.
  • the delineator shown generally as 10, is constructed of a plastic binder with reinforcing fibers.
  • the plastic binder may be any suitable plastic which is capable of withstanding the variations of temperature to which it will be subjected and which possesses the desired elongation characteristics to prevent massive fracturing upon impact.
  • Thermosetting resin material is particularly well suited for this application in as much as it is not dependent upon temperature to maintain its flexibility. To the contrary, many thermoplastic materials become too brittle when exposed to subfreezing temperatures and result in massive fractures upon impact with a moving vehicle. Where the thermoplastic resin is capable of withstanding temperature variation without concurrent hardening, however, such material may well be suited as binder material for the subject invention.
  • thermosetting/thermoplastic resin combinations may well be suited as binder material as long as this combination is capable of withstanding a temperature variation without concurrent hardening and has a modulus of elasticity approximating that one of a thermosetting resin.
  • reinforcing fiber is embedded within the binder material.
  • a portion 17 of this fiber is positioned longitudinally along the length of the delineator structure.
  • a high modulus fiber such as "Kevlar" (Trademark) may be used.
  • a second layer 16 of fiber material is oriented in random direction to establish tensile strength and to contribute to the proper balance between rigidity and flexibility.
  • a surface coating 15 is utilized to protect the contained binder/fiber combination from weather, ultraviolet rays and other adverse effects of the environment.
  • the arrangement of longitudinal versus random fibers within the structure may be varied such that the randon fiber may form a core, with the longitudinal fiber comprising the second layer thereon.
  • the random fibers are transverse with respect to each other; however, they do not cross each other at predetermined angles.
  • the transverse fibers at 36 in Figure 3 are in traversing arrangement because the fibers making up this portion of the delineator cross each other at predetermined angles (approximately 90°). This is in contrast to the "longitudinal fibers" which run substantially parallel with respect to each other. To prevent shearing of the rib, at least seven percent by weight of fiber therein would be in random or traversing orientation and intermingled or connected with the web.
  • the binder material comprises twenty to forty percent by weight of the delineator structure
  • use of more than sixty percent random fiber adversely affects the elastic character which is required to restore the delineator to its original position after impact.
  • failure to use at least forty percent of the fiber in the longitudinal orientation, without other reinforcing structure will result in insufficient resilience or elastic modulus to permit the delineator to be driven into the ground.
  • This use of proper amounts of fiber coordinated between transverse and longitudinal orientations represents an effective method of establishing the appropriate E and I within the delineator structure.
  • a second method for establishing sufficient elastic modulus while preserving resistance to a buckling load is accomplished through geometrical configurations such as shown for example by the rib structures 11 and 13 in Figure 1.
  • rib structures 11 and 13 in Figure 1.
  • the effect of slightly protruding rib structure is to extend the apparent thickness of the delineator and thereby increase the moment of inertia I, without subjecting the rib structure to excessive stress during the dynamic bending phase.
  • rib structure may be omitted and both E and I can be satisfied by the use of proper orientations of reinforcing fibers in combination with a nonplanar (i.e. concavo-convex) web structure.
  • a slightly concavo-convex delineator body properly reinforced with fibers, can withstand a limited driving load imposed at the top thereof while retaining sufficient flexibility to bend without destructive deformation.
  • the concavo-convex body may be additionally reinforced with longitudinal ribs at its side edges.
  • FIG. 3 and 3a An additional configuration is illustrated in Figure 3 and 3a, in which a single rib 31 supplies the reinforcing strength to permit driving of the delineator into the hard surface.
  • the reinforcing rib 31 is located on a non-impacting surface 34 of the delineator 30.
  • the thickness of the web portion 32 will depend upon the anticipated impact force associated with the delineator environment.
  • the full web with reinforcing rib structure is fully reinforced with the appropriate combination of transverse and longitudinal fibers 36 and 37.
  • a somewhat larger rib thickness might be desired to increase moment of inertia and longitudinal rigidity.
  • This larger rib size will improve drivability, excessive size will reduce the desired flexibility required for withstanding bending stress.
  • This reduction in flexibility may be partially alleviated by reducing longitudinal fiber content in the rib body and slightly increasing the transverse fiber arrangement to develop a minor fracture capability upon the initial impact of a bending force with the delineator.
  • the delineator prior to bending impact, has increased longitudinal rigidity to withstand the anticipated driving force to be applied during installation. After installation, however, a reduction of moment of inertia and improved flexibility to withstand bending stress is achieved upon an initial impact which develops transverse fractures 33 along the rib length.
  • An additional method of developing high EI in fiber reinforced plastics as described herein for drivability, but lower EI during bending movements is to incorporate a network of microspherical voids within the delineator structure. This concept is illustrated in Figure 4a. Such voids 45 can be introduced during fabrication by conventional techniques and will operate to lower the moment of inertia and thereby enhance flexibility. Furthermore, although longitudinal rigidity will be retained due to static strength inherent in this configuration, a violent lateral impact will cause the microspheres to partially collapse and operate as tiny hinges to facilitate bending movement.
  • FIG. 4 As shown best in Figure 4, other geometrical configurations can be used in combination with the proper fiber and resins content as previously referenced to establish a balance between E and I.
  • the particular configuration shown in Figure 4 utilizes structural thickness to develop the increased elastic modulus required to obtain drivability for the delineator 40.
  • rib structures 43 at the edges of the web structure 42 and a thicker central portion of web structure 41 an increased effective thickness is obtained to satisfy ultimate buckling load requirements.
  • Such effective thickness extends from the front contacting edges of the forward extending ribs 43 through the rearward ridge of the central reinforcing rib 41.
  • the hard ground structure forces the delineator to retain its static configuration, having an apparent thickness extending from i to iv. It is this extended thickness d t which strengthens longitudinal rigidity in the otherwise thinned web structure between ii and iii, and provides the higher EI for this condition.
  • a common feature of each embodiment described and claimed herein is that a unibody construction exists which incorporates the intermingling of fibers and resin within composition ranges and fiber orientations which provide transverse flexibility and longitudinal rigidity in the same structure.
  • E is increased by loading the delineator with at least 4096 fiber in the longitudinal direction.
  • I is increased by configuring the cross-section geometry with rib structure or non-planar shape to improve column strength.
  • the first embodiment of this invention involves the construction of a delineator using fiber reinforced plastics wherein the E of the delineator material enables use of a geometric configuration with a low I to enhance flexibility. Column strength is concurrently developed with reinforcing rib structure by incorporating this geometric configuration and/or a non-planar configuration to increase I in the longitudinal direction without disrupting the low I required for flexibility.
  • the higher EI is realized in the reinforced sections of the delineator which operate as the primary load bearing element. Such occurs, for example, at the central ridges, distal ribs, or any areas of greater thickness.
  • the angular contortion of the more flexible web portion of the structure provides a reduced moment of inertia and therefore a reduced stress due to the decreased distance between the neutral axis and the various points of stress along the delineator body.
  • a removable, rigid-body casing 81 may be positioned around a portion of the delineator structure 80.
  • the effect of this rigid-body casing is to reduce the length of the delineator exposed to buckling forces during installation procedures. This reduced length decreases the denominator of equation (1 thereby increasing the ultimate buckling load. It is noted that since the length parameter of the referenced equation is squared, any reduction in length greatly magnifies the increase in buckling load capable of being withstood.
  • Typical construction materials used for the rigid-body casing 81 would be steel or other heavy-duty substances capable of withstanding buckling pressures exerted by the delineator contained within the casing. Additionally, the casing may be capped with an impactable substance which serves to disperse the driving force along the top edge 83 of the delineator body 80. By utilizing such a rigid-body casing, the strength of the reinforcing rib material required for installation is reduced.
  • the preferred structure for the rigid casing would have the inner surface conformed to the outer surface of the delineator body to be enclosed. This would restrain any lateral movement and essentially eliminate that enclosed section from the total length of the delineator subject to equation (1). ).
  • the reinforcing rib structure located at the contacting face of the various delineators illustrated herein may also provide protection for sign materials affixed to the delineator face.
  • the sign material 21 will generally always be attached at the impacting surface of the delineator 20. Without protective ridging, the sign surface would be exposed to scraping or other destructive forces as it contacts the underside of cars or other impacting objects.
  • the lateral ridges protruding forward from the contacting surface minimize contact with the actual sign surface attached thereto. Such protection is especially important with less durable sign surfaces such as reflective tape.
  • water may locate behind the reflector covering, and upon freezing, dislodge the material from the delineator surface. For this reason, a small notch is located along a top edge 22 of the delineator surface. The top edge of the tap is then recessed into the notch and protected from the weathering conditions which would otherwise tend to detach the material.
  • top reflector edge is to use a protective cap 91 as shown in Figure 9.
  • the top edge 92 of the reflective surface 93 is retained within the enclosed region of the cap structure. In this configuration, exposure to rain, snow and other adverse weathering elements are minimized and reflector utility is preserved.
  • a supplemental benefit of the capped configuration is the protection given to the top edge of the delineator during impact with vehicles. During this impacting contact, the delineator will strike the underside of the vehicle numerous times in attempting to restore itself upright. After repeated occurrences, the top edge of the delineator will tend to fray or otherwise degrade. By using a thermoplastic cap having impact resilience and resistance to ultraviolet radiation, the top edge is protected from such abrasion. Typically, such a cap is fitted after placement of the delineator 90 into the ground, since the installation driving force is preferably applied to the rigid top edge of the delineator body.
