ABSTRACT:
A parking bumper shell that can be easily filled with a heavy form-filling material (such as concrete) to form a parking bumper is provided. The parking bumper shell may be injection molded from durable, brightly-colored, UV- and weather-resistant plastic. Undercuts, such as in the form of a plurality of undercut wings or z-puller pins, may be disposed on the interior of the parking bumper shell's top and side walls to aid in holding the parking bumper shell and the heavy filling material together. The parking bumper shell may also include internally projecting hollow extensions that are adapted to receive anchoring posts. While the parking bumper shell is being filled, it may be placed in a rigid frame which helps the shell to keep its shape during filling. The parking bumper shells are light-weight, nestable, and do not require internal steel rebar reinforcement, thereby greatly reducing transportation costs.
