  • Collapsible crab trap with a center bait feeder and weighted side doors
    Patent number: 5353541
    Abstract: A collapsible crab trap is provided with a centrally-located bait feeder made of wire mesh material. The trap and bait feeder are movable between a collapsed configuration and an assembled configuration. When in a collapsed configuration, it is easy to store or transport. The centrally-located bait feeder apparatus is constructed in such a manner that the crabs cannot remove an entire piece of bait from the bait feeder. Another feature of this crab trap is that the two side panels are weighted along their upper edges to positively open the side panels when on the ocean bed for the catching of crabs. These weighted side panels also provide a stable placement of the crab trap in strong moving currents.
