Abstract
The hooked ends of the springs or like members by which the bed of a trampoline or similar apparatus is suspended from its frame are equipped with protective sleeves of flexible material. The sleeves are split at their outer ends to form two flaps, one of which covers the exposed ends of the hooks to prevent injury to a performer inadvertently striking them, while the two flaps together are foldable back onto the sleeve to assist hooking and unhooking of the springs to and from the bed and the frame.
