US 4,730,411 A · Collapsible marine trap

Abstract

A collapsible trap is disclosed characterized by a net member and a folding frame member, the frame being disposed within the net member and adapted to be erected to form an enclosure therewith. The net member has an entrance including an opening to permit water creatures to enter the trap and to hinder leaving the trap. The folding frame member disposed within the net member comprises first and second annular members attached to the net member in spaced parallel relationship. A plurality of folding longitudinal members join the first and second annular members together. Each of the longitudinal members comprises a pair of arms having disatal and proximal ends. The distal ends of the arms are pivotally attached to annular members. The proximal ends of each of the arms of the longitudinal members are pivotally joined together to thereby permit the longitudinal members to be folded inwardly of the net to collapse the trap and unfolded outwardly to erect the trap with a limiting member limiting the outward movement of the longitudinal members beyond the erected position.

In a collapsible trap characterized by a net member and a folding frame member, the frame being disposed within the net member and adapted to be erected to form an enclosure therewith, the net member having an entrance including an opening to permit water creatures to enter the trap and to hinder leaving the trap, the improvement comprising:

the net member being formed of a foldably resilient mesh material and having generally spheroidal configured side surface in the erected mode with approximately flat top and bottom portions and a relatively flat generally circular configuration in the collapsed mode;
the folding frame being disposed within said net member and comprising:
first and second annular members attached to said net member in spaced parallel relationship;
a plurality of curved folding longitudinal members joining said first and second annular members together;
each of said longitudinal members comprising a pair of arms having distal and proximal ends;
means pivotally attaching the distal ends of said arms to said annular members;
and
other means pivotally attaching the proximal ends of said arms together to thereby permit said longitudinal members to be folded inwardly of said net to collapse said trap and unfolded outwardly to erect said trap.

the folding frame being disposed within said net member and comprising:
first and second annular members attached to said net member in spaced parallel relationship;
a plurality of curved folding longitudinal members joining said first and second annular members together;
each of said longitudinal members comprising a pair of arms having distal and proximal ends;
means pivotally attaching the distal ends of said arms to said annular members;
other means pivotally attaching the proximal ends of said arms together to thereby permit said longitudinal members to be folded inwardly of said net to collapse said trap and unfolded outwardly to erect said trap;
an inwardly extending entrance disposed in the top portion of said net member;
an access opening disposed in the bottom portion of said net member;
and
means for closing said access opening while said trap is in use.
