Retrieval Float

Abstract

The disclosed device is a retrieval float for use during spear fishing and diving. The retrieval float allows a diver to send marine organisms that have been caught by various underwater methods to the surface. By eliminating the practice of securing catches to oneself for the duration of the dive, the retrieval float decreases the chances of dangerous encounters with underwater predators that are attracted to blood. A fish, lobster, abalone, or other marine organism is secured to the retrieval float and returned to the surface for a spotter boat to collect.

Description

FIELD

This invention relates to the field of fishing and diving and more particularly to a system that allows a diver to float fish, lobster, and other marine organisms caught by various methods to the surface.

BACKGROUND

When diving or spear fishing, a diver typically attaches caught fish, lobster, abalone, or other marine organisms to herself until she returns to the surface. As one might expect, attaching bloody fish to oneself while diving can lead to unwanted encounters with marine predators that are attracted by the smell of blood.

What is needed is a way to minimize the risk of dangerous encounters while catching marine prey by various underwater catching methods.

SUMMARY

The solution is a device that floats catches to the surface for retrieval by a boat or vessel. The disclosed device, or retrieval float, is a series of flotation devices that are held to the diver. While underwater, the diver attaches caught fish, lobster, abalone, or other marine organisms to a float that is subsequently inflated. After inflation the diver releases the float, the float then rising to the surface for pickup by a spotter boat.

In addition to retrieval, the retrieval float signals to the boat the location of the diver. In situations with multiple divers, the retrieval floats are individually labeled with each diver's name. This allows the boat to track the specific catch by each diver as well as the location of each diver.

The retrieval float has following components: a plurality of standard floats and a soft stringer to which the standard floats attach.

Each standard float is further comprised of a spike, a spike line, a bladder, an inflation valve, an air release valve, and a retrieval strap.

In additional embodiments, the spike may be replaced with a hook, a clasp, a clip, a noose, or a net. The type of securing means is determined based on the type of marine organism being attached.

For ease of discussion, the following explanation will be directed to a float having a spike and sending a caught fish to the surface. The standard floats are used in the following manner:

The fish is secured to the standard float by inserting a spike through the eyes of the fish. The spike is a rod with a pointed tip for insertion through a fish. The spike is attached to the float via a spike line. The spike line is a cord or line that connects the spike and float.

The standard float has a bladder to hold air, thereby rendering the standard float buoyant. The inflation valve is configured to keep water out but allow air to pass into the bladder when mated with the air hose. When the diver has on full scuba gear, the bladder is filled with air from a diver's tank via an inflation valve. But during a free dive, the bladder may be inflated by mouth or using a carbon dioxide cartridge.

As the float ascends to the surface, the external water pressure gradually decreases. The air release valve exhausts air from the bladder during ascension to prevent failure of the float due to over-pressurization and subsequent expansion.

Each float includes a retrieval strap. The retrieval strap is a loop used for retrieval of the float. At the water's surface the retrieval strap is either grabbed by hand, or hooked, to bring the float and catch to the boat.

Now turning to a discussion of the soft stringer. The soft stringer is a support structure that attaches to the diver, holding the floats during a dive. The soft stringer includes the following parts: a frame, one or more removable fasteners, an attachment clip, a final spike, and a spike line.

The frame is the portion of soft stringer to which all items attach. The standard floats attach to the soft stringer via removable fasteners. In one embodiment the final float is permanently affixed to the soft stringer. In alternative embodiments the final float is removable for replacement in the event of damage.

The final spike is attached to the soft stringer by a spike line, rather than being attached to the bladder of the final float.

DETAILED DESCRIPTION

Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.

Referring now to FIG. 1, a kit containing all materials for the retrieval float is shown. The retrieval float kit 1 comprises a bag 2, an inflation hose 4, and a float storage assembly 10. The float storage assembly 10 is comprised of five standard floats 14 that are removably attach to the soft stringer 38. A final float 16 is affixed to one end of the soft stringer 38.

In some embodiments, the standard floats 14 and final float 16 may be different colors so that the retrieval boat will know when the diver sends up the final float 16.

There is an attachment clip 12 on the soft stringer 38 on the end opposite the final float 16. The attachment clip 12 secures the float storage assembly 10 to a diver.

The air hose 4 has two ends: the regulator attachment 6 and the inflation end 8. The regulator attachment 6 connects to the first stage of a diver's regulator. The inflation end 8 mates with the inflation valve 28 (not shown) to inflate a bladder 29.

Referring now to FIG. 2, a front view of the float storage assembly 10 is shown. On this side of the float storage assembly 10, two standard floats 14 and the final float 16 are shown attached to the soft stringer 38.

Referring now to FIG. 3, a side view of the float storage assembly 10 is shown. The side view provides a better understanding of the orientation of the six floats 14/16 when all six are attached to the soft stringer 38, resulting in a full float storage assembly 10.

Referring now to FIG. 4, a rear view of the float storage assembly 10 is shown. This side of the float storage assembly 10 shows three standard floats 14 attached to the soft stringer 38.

Referring now to FIG. 5, a view of the float storage assembly 10 is shown. The five standard floats 14 are shown removed from the soft stringer 38. With the standard floats removed, the removable fasteners 41 are shown. The final float 16 remains affixed to the soft stringer 38.

The final spike 40 is held under the removable fasteners 41 by the final spike channels 42. The final spike 40 attaches to the soft stringer 38 via a spike line 30. The spike line 30 is attached to the soft stringer 38 near the upper end of the soft stringer 38, adjacent to the attachment clip 12.

Also shown is the safety tape 36 on the back of a standard float 14.

Referring now to FIG. 6, a standard float 14 is shown removed from the float storage assembly 10 and opened. The standard float 14 includes: the a-strap 18, b-strap 20, c-strap 22, air release valve 24, retrieval strap 26, inflation valve 28, bladder 29, spike line 30, spike 32, spike trap 34, and safety tape 36 (see FIG. 5).

Each standard float 14 is stored in its rolled position before being secured to the float storage assembly 10. The floats 14/16 are rolled up from the retrieval strap 26 end to the spike trap 34 end. Once rolled up, the b-strap 20 is folded over, then the a-strap 18 is folded across the b-strap 20, then the c-strap 22 is folded across the a-strap 18 and fastened to the b-strap 20.

Now turning to a discussion of using the retrieval float 1. When a fish is ready to be sent to the surface, one standard float 14 is removed from the float storage assembly 10. Next, the standard float 14 is unrolled and the spike 32 is extracted from the spike trap 34. The spike 32 is pushed through the eyes of a fish, or other area of the fish suitable for securing via puncture. With the entire spike 32 through the fish, the fish is secured on the spike line 30 with the spike 32 being perpendicular to prevent the fish from sliding off the spike line 30.

Next, the inflation end 8 is mated with the inflation hose 4 using the inflation valve 28. The bladder 29 is filled with air from the regulator in a matter of seconds.

Once the bladder 29 is inflated, the standard float 14 is carried to the surface by its buoyancy.

As the standard float 14 rises, the external pressure decreases. To prevent over-expansion or explosion of the bladder 29, the air release valve 24 burps air out of the bladder 29 as the external pressure decreases.

When the standard float 14 surfaces, the bright color and reflective safety tape 36 make it easily visible for a vessel find. The fish and the standard float 14 is scooped, hooked, or grabbed out of the water using the retrieval strap 26.

In some embodiments, the safety tape 36 may even have the name of a diver written on it. This feature is most useful when multiple divers are out at the same time.

Referring now to FIG. 7, the final float 16 is shown. The final float 16 is longer than the standard floats 14. The purpose of a longer float is the ability to load multiple fish onto the final float 16. This feature is helpful when a diver has a particularly successful day of spear fishing. For example, if the diver is on her final float 16, she has already successfully sent five fish to the surface. But if she comes across another school and successfully spears two or more fish, a larger buoyancy force will be required to raise that load to the surface. The increased buoyancy is created by a longer final float 16 that has a larger bladder 29.

Another difference is the final spike 40 is attached to the spike line 30 at a three-quarter point instead of in the center like the standard spikes 32. The three-quarter attached final spike 40 makes it easier to push the spike through multiple fish.

Another benefit of the final float 16 being longer is that the vessel will know that the diver has completed her dive and will be surfacing soon and near the position of the final float 16.

In some embodiments, the final float 16 is a different color.

Referring now to FIG. 8, a diver is shown with the retrieval float kit 1 attached to her dive gear via the attachment clip 12. The inflation hose 4 is connected to her regulator and secured through her shoulder strap in an easily accessible location to apply the inflation end 8 to the inflation valve 28.

Referring now to FIG. 9, the diver has removed a standard float 14 and is mating the inflation end 8 of the inflation hose 4 to the inflation valve 28.

Referring now to FIGS. 10 and 11. FIGS. 10 and 11 illustrate a feature of the inflation valve 28 that prevents water from entering the bladder 29 but allows air to enter the bladder 29 when mated with the inflation hose 4. That feature is a depressible tip. When the tip is in the normal state, the tip is raised by an internal spring mechanism. In the normal state, no air or water may pass through the inflation valve 28. When mated with the inflation end 8 of the inflation hose 4, the inflation end 8 depresses the tip of the inflation valve 28. When depressed, air may pass into the bladder 29.

In FIG. 10, a close-up view of the diver about to engage the inflation end 8 with the inflation valve 28 is shown. The tip of the inflation valve 28 is shown in the normal state.

Referring now to FIG. 11, shows a close-up view of the inflation valve 28 receiving air from the inflation hose 4. The tip of the inflation valve 28 is shown being depressed.

Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
