ABSTRACT:
An improved bowling alley bumper system for selectively guarding against the throwing of gutter balls. An elongated guard is supported alongside the gutter and can be pivotally retracted or extended between a first position in which the gutter is exposed and unguarded and a second position in which gutter entry by a bowling ball is precluded by constructing the predominant portion of the system of prefabricated modular sections of relatively lightweight component parts, they can be longitudinally positioned end-to-end enabling significant cost savings to be realized for both fabrication and installation.
