The present invention relates generally to the field of hunting tools. More specifically, the present invention is a modular spear having three interchangeable sections.
Bow fishing has grown in popularity over the years due to a number of reasons, such as increased exposure to the sport and the growing populations of invasive species like rough fish. To legally partake in the sport of bow fishing, one must tether their arrows before firing them into the water. This is to prevent fish from escaping, taking along with them the arrow, which could pose an ecological threat to the waterways, danger to other humans or animals, etc. While the popularity of bow fishing has increased, it is still not inclusive to all parties, namely, disabled people or people who cannot otherwise operate a bow. For example, someone missing a limb would find difficulty in notching an arrow and firing a bow. Thus, a single-handed instrument would be ideal for such handicapped individuals wishing to partake in the sport of bow fishing. A tethered spear would provide the ideal single-handed instrument for achieving a feeling similar to that of using a bow.
The spear is a hand thrown multi-use tool that can be used to harvest fish, alligators, and any legal big game animals. When using a spear for hunting fish, alligators or crocodiles, spear game law requires the tool to be tethered or have a line attached to it. The user then has the option to retrieve the quarry by hand with the tether or use a fishing pole/reel for added sport. If so desired, a floating device can also be attached to the tether (typical when hunting alligators and crocodiles), etc. When used as a game spear the user could attach a tracking string to aid in the recovery of game or recovery of the spear. In some instances, a standard lighted component/receiver could be attached to the back end of the spear as a means of tracking of game and or recovery of the spear. While it is evident that a means of attachment for a tether, or other peripheral, are helpful or necessary in many hunting situations, many spears are not adapted for such attachments. Furthermore, there is not an easy way for modifying a spear in order to accommodate the attachment of a tether.
When spear hunting it can be common for the spear tip to become damaged, or broken completely, thus requiring replacement. Replacing a broken or damaged spear tip is an arduous process and typically involves the use of an adhesive which takes time to set, thus preventing spears from being fixed in a practical manner while out hunting. Furthermore, in extreme cases it may be impossible for the spear tip alone to be replaced, thus adding on to the cost incurred by the user.
Therefore, it is an object of the present invention to provide a modular spear having three modular sections. The present invention includes a spear tip, a spear shaft, and a tail end, wherein the spear tip and the tail end are removably attached to opposite ends of the spear shaft. This allows one or more pieces of the present invention to be replaced independent of each other, thus leading to less costs incurred by the user and time saved when performing modifications or replacements. The spear shaft includes a first fastener assembly and a second fastener assembly that allow for the secure attachment of the spear tip and the tail end. Furthermore, the first fastener assembly and the second fastener assembly allow for the quick attachment or removal of the spear tip and the tail end to or from the spear shaft. This allows the user to switch tips for the correct application in an efficient manner (e.g. transitioning from a practice head to a hunting broad head to a spearfishing head).
With the growing population of invasive rough fish (and other species of fish) and the growing popularity of bow fishing, the present invention aids in adding new dimensions to the sport. Users can experience the past while aiding in the control of invasive rough fish (and other overpopulated species). The present invention also allows individuals with physical limitations to target rough fish. While these limitations prevent them from being able to draw and shoot archery equipment (the most common tool for harvesting rough fish), the present invention can be operated with one hand making it more accessible to a greater number of people. Rough fish are here to stay, so we might as well take every advantage of the resource.

The present invention is a modular spear having three interchangeable sections. More specifically, the present invention comprises a spear tip 1, a spear shaft 2, and a tail end 3. In reference to
The spear shaft 2 accounts for a majority of the length of the present invention, wherein the spear shaft 2 comprises an elongated body 20, a first receiving cavity 21, and a second receiving cavity 22. The elongated body 20 provides the main body of the spear shaft 2 and is the portion of the present invention that is held by a user when throwing the present invention. The first receiving cavity 21 and the second receiving cavity 22 terminally traverse into the elongated body 20, wherein the first receiving cavity 21 and the second receiving cavity 22 are positioned opposite each other along the elongated body 20, as depicted in
In reference to
In reference to
To attach the spear tip 1 to the spear shaft 2, the first set screw 233 and the first compression fastener 232 are loosened or removed entirely. The first set screw 233 may be fully removed from the threaded hole bored through the first receiving fitting 230 and the elongated body 20, or the first set screw 233 may be loosened, such that the first set screw 233 does not obstruct the full passage of the first the spear tip 1 into the first receiving cavity 21. The first compression fastener 232 may be fully detached from the first receiving fitting 230, or the first compression fastener 232 may be loosened, such that the first compressions fitting is relaxed from the first receiving fitting 230 and the first ferrule 231 is decompressed. With the first set screw 233 and the first compression fastener 232 either loosened or removed, the spear shaft 2 is positioned through each of the first compression fastener 232, the first ferrule 231, and the first receiving fitting 230 into the first receiving cavity 21. The first set screw 233 and the first compression fastener 232 are then tightened to secure the spear tip 1 to the spear shaft 2.
In such embodiments, the first receiving fitting 230, the first ferrule 231, and the first compression fastener 232 form a compression fitting. As the first compression fastener 232 is tightened onto the first receiving fitting 230, the ends of the first ferrule 231 are clamped around the spear tip 1, thereby securing the spear tip 1 to the spear shaft 2. Meanwhile, the addition of the first set screw 233 provides a dual-means for securing the spear tip 1 to the spear shaft 2. As the first set screw 233 is tightened, the first set screw 233 laterally engages the spear tip 1, wherein the first set screw 233 applies a lateral force on the spear tip 1 that clamps the spear tip 1 between the first set screw 233 and the interior wall of the elongated body 20. The dual-means of securing the spear tip 1 to the spear shaft 2 provides a failsafe in the event that either the first set screw 233 or the first fastener assembly 23 fails during implementation of the present invention.
To detach the spear tip 1 from the spear shaft 2, the first set screw 233 is loosened or removed entirely. Similarly, the first compression fastener 232 is loosened or detached from the first receiving fitting 230 entirely, such that the first compression fastener 232 is able to freely slide along the spear tip 1. With the first set screw 233 and the first compression fastener 232 either loosened or removed, the spear shaft 2 is pulled out of the first receiving cavity 21 and out through each of the first receiving fitting 230, the first ferrule 231, and the first compression fastener 232.
In reference to
To attach the tail end 3 to the spear shaft 2, the second set screw 243 and the second compression fastener 242 are loosened or removed entirely. The second set screw 243 may be fully removed from the threaded hole bored through the second receiving fitting 240 and the elongated body 20, or the second set screw 243 may be loosened, such that the second set screw 243 does not obstruct the full passage of the second the tail end 3 into the second receiving cavity 22. The second compression fastener 242 may be fully detached from the second receiving fitting 240, or the second compression fastener 242 may be loosened, such that the second compressions fitting is relaxed from the second receiving fitting 240 and the second ferrule 241 is decompressed. With the second set screw 243 and the second compression fastener 242 either loosened or removed, the spear shaft 2 is positioned through each of the second compression fastener 242, the second ferrule 241, and the second receiving fitting 240 into the second receiving cavity 22. The second set screw 243 and the second compression fastener 242 are then tightened to secure the tail end 3 to the spear shaft 2.
In such embodiments, the second receiving fitting 240, the second ferrule 241, and the second compression fastener 242 form a compression fitting. As the second compression fastener 242 is tightened onto the second receiving fitting 240, the ends of the second ferrule 241 are clamped around the tail end 3, thereby securing the tail end 3 to the spear shaft 2. Meanwhile, the addition of the second set screw 243 provides a dual-means for securing the tail end 3 to the spear shaft 2. As the second set screw 243 is tightened, the second set screw 243 laterally engages the tail end 3, wherein the second set screw 243 applies a lateral force on the tail end 3 that clamps the tail end 3 between the second set screw 243 and the interior wall of the elongated body 20. The dual-means of securing the tail end 3 to the spear shaft 2 provides a failsafe in the event that either the second set screw 243 or the second fastener assembly 24 fails during implementation of the present invention.
To detach the tail end 3 from the spear shaft 2, the second set screw 243 is loosened or removed entirely. Similarly, the second compression fastener 242 is loosened or detached from the second receiving fitting 240 entirely, such that the second compression fastener 242 is able to freely slide along the tail end 3. With the second set screw 243 and the second compression fastener 242 either loosened or removed, the spear shaft 2 is pulled out of the second receiving cavity 22 and out through each of the second receiving fitting 240, the second ferrule 241, and the second compression fastener 242.

In some embodiments of the present invention, the elongated body 20 may be designed to be more aerodynamically efficient. This allows for the present invention to be thrown farther and with greater accuracy. As such, and in reference to
In some embodiments of the present invention, the inner wall of the elongated body 20 that delineates the first receiving cavity 21 is threaded. Similarly, the inner wall of the elongated body 20 that delineates the second receiving cavity 22 is threaded. Furthermore, the spear tip 1 and the tail end 3 each have a threaded end for engaging with the spear shaft 2. More specifically, the free end of the tip shaft 10 (i.e. opposite the spear head 12) is threaded, while the free end of the tail shaft 30 (i.e. opposite the line connector 31) is threaded. To attach the spear tip 1 to the spear shaft 2, the tip shaft 10 is simply screwed into the first receiving cavity 21, and to remove the spear tip 1 from the spear shaft 2, the tip shaft 10 is screwed out of the first receiving cavity 21. Similarly, to attach the tail end 3 to the spear shaft 2, the tail shaft 30 is simply screwed into the second receiving cavity 22, and to remove the tail end 3 from the spear shaft 2, the tail shaft 30 is screwed out of the second receiving cavity 22.
