DETAILED DESCRIPTION OF THE INVENTION

(16) Referring now to FIGS. 1, 4, 5, 9, 10-13 of the drawings, a first embodiment of apparatus constructed in accordance with the teachings of the present invention is illustrated. The apparatus includes an elongated hollow shell 10 for attachment to an upper portion of a roadway barrier segment and for topping the upper portion to prevent a passing bicycle and cyclist from extending or vaulting over the upper portion or snagging the passing bicycle and cyclist. The shell 10 may be constructed of polymer or other suitable material.

(17) The elongated hollow shell 10 has a shell top 12, a shell bottom 14, opposed shell side walls 16 extending between the shell top and shell bottom, and shell ends 18 extending upwardly from the shell bottom to the shell top.

(18) The shell bottom 14 generally conforms in size and shape to an upper roadway barrier segment surface 20 of a roadway barrier segment 22 (shown in solid lines in FIG. 11 and dash lines in other figures) so that the shell does not snag a passing bicycle and cyclist.

(19) The illustrated roadway barrier segment 22 is of known construction and is merely representative of the roadway barrier constructions with which the present invention may be utilized. The terms roadway barrier and roadway barrier segment encompass all types of highway barriers, including guardrail systems. As is conventional, in the disclosed roadway barrier, the roadway barrier segments are secured at the ends thereof by suitable connector structure whereby a plurality of roadway barrier segments form an elongated string.

(20) FIG. 10 shows a bicycle 24 next to a string of connected roadway barrier segments 22 and in accordance with the present invention (and as shown in FIG. 10) the shell 10 is attached to and tops the upper portions 26 of the roadway barrier segments, being sized and positioned to prevent a bicycle such as bicycle 24 from extending over the upper portion, which could result in injury.

(21) When installed, the shell side walls 16 and opposed shell ends 18 are substantially aligned with sides and ends of the upper portion of the roadway barrier segment. The opposed shell side walls and opposed shell ends extend upwardly.

(22) The shell top 12 attached to the opposed shell side walls and the opposed shell ends is configured to define a shell top upper surface curved over substantially the full extent thereof including a plurality of converging convexly curved shell top upper surface portions 32, 34, 36, 38. The shell top upper surface structural shape, while preventing a bicycle from extending over the upper portion, does not snag or otherwise affect to any significant degree forward progress of the bicycle and cyclist. Likewise, such shape will not cause any harm to the cyclist. The convexly curved shell top upper surface portions converge toward a location substantially midpoint along the shell top.

(23) The opposed shell ends 18 define recesses 40 at each of the ends.

(24) As perhaps may best be seen with reference to FIGS. 11, 12 and 13, the recesses 40 are partially defined by a recess bottom wall 42 at each end 18. The recess bottom wall has openings 44 located therein. The recess bottom wall 42 is spaced from shell bottom 14 and the openings 44 are in registry with bottom openings 46. The mounting hole 44 and the bottom opening 46 receive a bolt 48 used to secure the shell 10 to the upper portion of the roadway barrier segment.

(25) At each bolt location, prior to insertion of the bolt, and is shown in FIGS. 11, 12 and 13, a sleeve 48, for example an aluminum sleeve, is located between the mounting holes and the bottom opening for additional strength and crush resistance when setting mounting hardware. This allows for the use of an impact wrench when setting the hardware for the apparatus without fear of causing damage to the polymer shell.

(26) A raised channel 52 is formed at shell bottom 14, the raised channel 52 runs substantially the length of the shell bottom but terminates before reaching the opposed shell ends 18. This feature is an optional embedded structural feature that performs a desirable function when the first apparatus embodiment is converted into an outer shell employed in a second embodiment of the invention, which will now be described.

(27) The second embodiment of the invention is designated by reference numeral 60 and is shown in FIGS. 2, 3, 6, 7, 8, 9, 14 and 15. Apparatus 60 includes an elongated hollow shell 10A which is essentially the same as shell 10 described above, except that the shell 10 has been converted to shell 10A by having one of the ends cut off, providing an end opening 62. Opening 62 communicates with the shell interior and is located in opposition to the remaining shell end 18.

(28) This second embodiment of the invention includes a core member 64 having a core shell 66 and an end 68 attached to the core shell.

(29) End 68 has a recessed area 70 which is considerably larger than the recesses 40 on shell 10. The recessed area for example may be almost twice as wide to accommodate two aluminum sleeved holes of slightly lower diameter. These holes, identified in the drawings as reference numeral 72, are the primary mounting point for the core member 64 comprised of core shell 66 and end 68. The remainder of the length of the second embodiment 60 is designed to fit inside the converted and open ended shell 10A, being of smaller overall dimension and containing a raised channel 76 which fits on top of the raised channel 52 of the first embodiment and defines a groove 78 receiving the raised channel 52. This acts as a linear guide and when assembled the structural elements of the second embodiment will slide through the hollow section of the modified outer shell of the first embodiment. Once collapsed, the second embodiment of the invention is almost identical in length and identical in height to the first embodiment of the invention described above. The matingly engaged channels formed in the core shell and in the elongated hollow shell limit relative linear movement therebetween.

(30) As indicated above, the apparatus may be utilized with all types of roadway barriers, including guardrail systems. In the latter situation a flat beam, for example, could be used to provide an attachment support for the apparatus. The barrier could be a movable barrier, use of the apparatus on the barrier sections not interfering with barrier mobility.
