Background of the Invention
1. Field of the Invention
This invention relates to a collapsible fish spear and method of using such.
2. Prior Art Relating to the Disclosure
UNDERWATER SPORTS FISHING REQUIRES THAT THE SPORTS FISHERMAN CARRY A FULL LENGTH SPEAR FOR SPEARING FISH. Carrying of a full length spear is awkward and cumbersome. Some means has been needed to allow the underwater fisherman to carry a compact, collapsible spear which, with ease, can be assembled into a full-length spear for use in a matter of seconds.
Summary of the Invention
It is an object of this invention to provide a collapsible fish spear for use in underwater sports fishing which comprises a number of lengths of interlocking, hollow rods joined together by an elastic band which is tensioned to hold each of the lengths of rods in interlocked relation, the spear collapsed by pulling each length apart from the adjacent length and folding the rods together.
It is a further object of this invention to provide a collapsible fish spear which includes an elastic loop secured to the terminal end of rod for propelling the spear through the water to spear a fish.
It is a further object of this invention to provide a method of spearing fish underwater using a collapsible fish spear of the type described.
These and other objects are accomplished by providing a collapsible fish spear which comprises: (1) a series of lengths of hollow rod adapted to telescopically interlock together into a single length of rod, the lengths including a forward length with a fixed or removable spear, a terminal length and one or more intermediate lengths, (3) elastic means secured at one end to the forward length of rod and at the opposite end to the terminal length or rod, the elastic means extending under tension through the intermediate lengths of rod, and (4) an elastic loop secured at both end to the terminal length of rod for propelling the spear through the water when tensioned by the holder and released.

Description of the Preferred Embodiments
Referring to FIG. 2 the fish spear comprises a series of lengths of hollow rod which are telescopically interlocked together to form a single linear unit. The forward length 10 may be solid if desired and includes a projecting spear unit 18 extending therefrom. If desired, the spear unit may be removable as illustrated in FIG. 4 so that it can be interchanged with other spear units for spearing of different types of fish. The intermediate lengths of rod 12 and 14 are telescopically interlocked with each other and with the forward and terminal lengths 10 and 16, respectively. The ends 20 of the lengths of rod 10 and 14 are formed with an outer diameter slightly less than the inner diameter of the remaining constant diameter portion of the rod. This allows the lengths of rod to telescopically interlock with the adjacent rod as illustrated. Preferably the terminal ends 22 and 24 of the smaller and larger diameter portions of the rods are rounded so that the rods will easily telescope together.
An elastic band 26 is secured to the forward length of rod 10 at one end and to the terminal length of rod 16 at the other end, the elastic band extending through the hollow interior of the intermediate lengths of rod 12 and 14. The elastic band may be secured to the rods in any suitable manner. One means of securing the band is illustrated by FIG. 3 wherein the elastic band 26 is secured to pieces of cord 28 extending through eyelets 30 held in the end of the forward rod 10 opposite the spear unit 18 by fittings 32. A hole 34 is drilled in rod 16 near the terminating end thereby and a piece of cord 36 extended therethrough for securing closed elastic band 38 thereto. The closed, elastic loop 38 is used to propel the spear through the water. To propel the spear the loop is placed over the wrist, the spear is grasped, the loop tensioned and then released.
FIG. 4 illustrates one means of securing removable spear units to the tip rod 10. The tip rod 10 is provided with a section of lesser diameter and a groove 44 formed therein. A matching groove 42 is formed in unit 40 from which the spear lines 18 project. An expansion ring 44 secures unit 40 to the tip of the rod 10.
The collapsible fish spear an be carried underwater in collapsed condition with the user either grasping it so that it will not unfold or using a clasp to hold the spear in collapsed condition. When it is desired to expand the spear the clasp is removed or the grip of the user relaxed. The tension in the elastic band 26 causes the sections of rod to unfold and interconnect with one another into a spear of 5 to 6 feet as illustrated in FIG. 2 in a matter of seconds.
The spear unit is easy to transport underwater in the collapsed state, is compact, lightweight and can easily be expanded for use with one hand.
