发明名称 SLIDING COVER APPARATUS FOR ICE FISHING HOLE
摘要 An ice fishing accessory and safety appliance for an ice fishing hole, the apparatus having a stationary frame surrounding the hole and supported in a substantially horizontal plane relative to the ice. A movable cover mounted for sliding movement along a pair of substantially parallel guideways of the frame moves between an open position permitting access to the hole and a closed position obstructing the hole so a captured fish withdrawn from the ice hole cannot re-enter the hole and a fisherman will not accidentally slip through the hole. A pair of tensioned springs connected between movable cover and stationary frame move the cover from an open position to a closed position when a foot pedal actuated latch on the frame is released by the fisherman.
