发明名称 Spring door crab pot
摘要 A round crab pot provides crabs easy access from all directions, while strongly discouraging exit except by crabs of nonallowable small size. The pot may be of variable weight and size for commercial or individual use. The pot frame has an interchangeable top and bottom kept parallel by perpendicular supporting posts. The pot entrance occupies the entire height and circumference. The entrance is formed by a plurality of elongated spring steel rods connected to the top and/or bottom of the frame. The rods are positioned to slant inwardly toward the center of the pot and are connected by spring steel wire and a thin plastic medium. Thus, the entrance exhibits a spring-like tension as crabs enter. In a first variation, the rods are connected to only one end of the frame. Crabs may enter at ground level with the rods extending from the top of the pot, slanting inward and downward toward the center. By reversing the top and bottom, crabs may enter by walking up the rods. Rods of a lesser length may be attached to both the top and bottom of the pot. Crabs walk up the rods to the midpoint of the height of the pot and drop into the center. In both variations, the rods will not allow the crabs to exit.
