Hunting harpoon and associated methods
First Claim
1. A harpoon comprising:
- a shaft having a distal end and a pin receiving passageway formed in the distal end, the pin receiving passageway having a hook shape and including a releasing portion and a retaining portion in communication therewith;
a harpoon tip having an open proximal end for being received over the distal end of said shaft;
a pin carried by the open proximal end of said harpoon tip and cooperating with the pin receiving passageway to retain said harpoon tip on said shaft when said pin is in the retaining portion of the pin receiving passageway, and to release said harpoon tip from said shaft when said pin is in the releasing portion of the pin receiving passageway; and
a spring mounting said pin in the open proximal end of said harpoon tip.

Abstract
A harpoon includes a handle to be grasped by a user for placing the harpoon and a shaft having a proximal end connected to the handle. A distal end of the shaft has a pin receiving passageway formed therein. The pin receiving passageway may include a releasing portion and a retaining portion in communication therewith. The manual harpoon may also include a harpoon tip having an open proximal end for being received over the distal end of the shaft, and a pin carried by the open proximal end of the harpoon tip. The pin may cooperate with the pin receiving passageway to retain the harpoon tip on the shaft when the pin is in the retaining portion of the pin receiving passageway, and to release the harpoon tip from the shaft when the pin is in the releasing portion of the pin receiving passageway.
