Definitions
- the present invention relates to an impact recovery delineator system having a delineator post, a signage panel, and a fixed or portable base system which facilitates pivoting from a normally aligned, upright position to a substantially horizontal, yielded position upon being impacted by a moving object such as an automotive vehicle. More specifically, this invention relates to the unique load cell elements designed to reduce the impact force required to pivot the post upon impact, to speed the return of the post to its upright position, and ensure that the pivoting load assembly and the signage panel are properly oriented to direct traffic upon returning to the upright position.

- a self-uprighting delineator post construction is illustrated generally at 10 which incorporates a base 12, a load cell assembly illustrated generally at 30 and a light weight post 16.
- the upper end of the light weight post may be provided with a reflector 18 which may be attached with adhesive, bolted on or otherwise attached to the lightweight post to provide reflection of light, thus permitting the post to be readily visible under night driving conditions .
- the post and the reflector may be of a suitable color enabling it to be readily visible during daylight conditions.
- the material composing the post 16 may comprise any one of a number of suitable light weight polymer materials that are impact resistant. Since the post is of light weight construction, it does not present significant resistance to impact forces when it is accidentally struck such as by an automotive vehicle.
- a load cell assembly is illustrated generally at 30 which incorporates an upper load cell element 32 and a lower load cell element 34 which is supported by a base assembly generally shown at 36.
- the base assembly 36 incorporates a base plate 38 forming a lower surface 40 that is prepared in any suitable fashion to be placed (bonded or portable) to any suitable surface S, such as a roadway surface.
- the upper load cell element 32 has a central passage 42 and a lower load cell element also has a central passage 44 both of oval cross-sectional configuration to receive the two cable members 46a and 46b.
- the passages 42 and 44 are axially aligned.
- Fig. 2A illustrates a partial cross-sectional view of such a cable passage 42 as a single channel in upper load cell 34. Cables 46a and 46b extend there through.
- the upper and lower cell elements may be provided with two spaced apart cable channels 43 a and 43b as illustrated in Fig. 3 A.
- the single channel 42 and the double channels 43 a and 43b may provide with radiused edge portions to facilitate the yielding and uprighting features of the delineator post as will be discussed below.
- FIG. 3 illustrates passage system for the cables which pass through double channels in the upper and lower load cell elements.
- the upper load cell element 32 has a neck portion 50 and a cap section 52. Within the neck portion is a load spring neck cavity 54 (Figs. 6 and 10) for retaining the load spring 100 which causes the post 16 to bend and spring back as is known in the art.
- An upper cable passage 60 is formed by two spaced apart cable channels 43a and 43b which extend from inside the neck cavity 54 through the cap face surface 56 of the cap section 52.
- the cap face surface 56 has an orientation alignment member or edge 58 which cooperates with a complimentary orientation alignment member or edge 78 on the lower load cell element 34 to properly align the load assembly 30 and thus align the cables and delineator post 16 (with respect to the traffic flow) when the post moves from an upright orientation (Fig. 1) to a yielded position (Fig. 1A) and back to the upright position or when the delineator signage has been rotationally twisted.
- the lower load cell element 34 has a base section 80 and a head portion 82.
- a cable locking base cavity 84 (Figs. 5 and 9) is formed within the lower load cell element 34 to secure the spring loaded cables within the cell element. As can be seen in Fig.
- the lower load cell cable passage 86 is also formed by two spaced apart cable channels 83a and 83b which extend from inside the base cavity 84 through the base head face surface 85 of the base head portion 86.
- the lower load cell element 34 has an orientation edge 78 along the base head face surface 85.
- the upper cell element orientation edge 58 is disposed as a concave notch 90 in the cap section 52; and, more particularly, the edge 58 is an indentation along the cap face surface 56 between the cable channels 43a and 43b.
- the complimentary orientation edge 78 in the base head face surface of the lower load cell element is disposed as a convex ridge which extends across the head face surface 85, between the cable channels 83a and 83b. It should be understood that the orientation edges 58 and 78 may be reversed with the notch formed in the base head face surface of the lower load cell element and the ridge formed in the cab face surface 56. (See Figs. 5A, 6A, 9A and 10A) In operation, if the upper load cell element 32 is rotated or twisted (see arrow direction R in Fig. 3) with respect to the lower load cell element, the tapered sides of the face surfaces 56 and 86 and the orientation edges 58 and 78 become misaligned.
- Fig. 4 illustrates the embodiment of Fig. 3 with the spring load cables 46a and 46b extending through the cable passages made up of spaced apart cable channels in the upper and lower cell elements.
- the upper element 32 is shown in a partially flexed, yielded or deflected position and somewhat separated from the lower load cell element. This may occur when the delineator post is struck by an oncoming vehicle. The direction of traffic flow is parallel to the longitudinal axis of the alignment edges 58 and 78.
- FIG. 5 is a side elevation view of one embodiment lower cell element of the present invention.
- the head section 82 of the element has been tapered from the horizontal by an angle ⁇ .
- ⁇ is in the range of about 5° to about 20°, the realignment of the load assembly is enhanced.
- An angle of 13 ° appears to provide the most reliable realignment of the assembly.
- the height h of ridge 58 is equal to the depth d of the notch 78 (Fig. 6) to ensure proper engagement of the cells after displacement of the delineator upon impact or twisting.
- Fig. 6 illustrates in a side elevation plan view the cooperating upper load cell element 32 for element 34 of Fig. 5.
- the embodiments of Figs. 5 and 6 show the use of two spaced apart cable channels while Figs.
- the cable channels 83 a and 83b may be provided with a radiused edges 87a, 87a', 87b and 87b'. These edges are formed on the sides of the cable channel holes whose tangent t is perpendicular to the direction of traffic (arrow T) or the direction in which the post is intended to deflect when struck. Again, the application of a radius to these particular edges of the channel openings while keeping the opposite side edges straight facilitates the yielding of the post on impact and the edges guide return to the upright position and improving the alignment of the load assembly. It should be understood that Fig.
- FIG. 8 shows the complimentary and cooperating upper load cell element with radiused edges 45a, 45a', 45b and 45b'.
- Figs. 9 and 10 illustrate the load cell elements 32 and 34 with a single cable channel having two spaced apart cables extending through the one channel. It should be understood from Figs. 11 and 12 that the radiused edges 42a, 42a', 44a and 44a' function in the same way as discussed above to facilitate post yielding and realignment.
- Fig. 5 A illustrates a side elevation view of a lower cell element 34a wherein the head portion has been provided with an orientation alignment notch 78a (rather than a ridge) and has two spaced apart cable channels 83a and 83b.
- Fig. 9 and 10 illustrate the load cell elements 32 and 34 with a single cable channel having two spaced apart cables extending through the one channel. It should be understood from Figs. 11 and 12 that the radiused edges 42a, 42a', 44a and 44a' function in the same way as discussed
- FIG. 6A shows a cooperating upper load cell element 32a.
- Figs. 9 A and 10 A show the reversed notch/ridge arrangement of cells 34a' and 32a' with single cable channels 44a' and 58a'.
