Abstract
Bumper bowling systems include retractable bumpers and mechanisms connected to the retractable bumpers disposed alongside a bowling alley's gutters. The mechanisms are adapted to extend the bumpers into a position which prevent bowling balls from falling into the gutter and also to retract the bumpers to permit ordinary bowling. A segmented longitudinally extending cap and a structural support member are also provided so that the cap covers the bumper mechanism.
