The present disclosure relates to the field of diving equipment and devices which may be used as a signaling device.
Scuba (Self-Contained, Underwater Breathing Apparatus) diving is very popular, and the number of scuba divers is ever-increasing in a wide variety of fields: military, commercial, and recreational. A scuba system allows a diver to reach significant depths and remain underwater for extended periods of time, offering a major advantage over breath-holding divers. While a scuba diver's ability to reach lower depths for extended periods of time is an advantage, it also engenders a host of challenges. For example, a scuba diver may encounter obstacles in a body of water or on the floor of a body of water that he or she would not have encountered in a breath-holding dive. Further, most scuba gear does not allow a diver to communicate with another diver using his or her voice. In addition, illumination from both natural light and artificial light is obscured as a diver descends deeper in the water. As a result, a member of a group of divers may easily become lost and separated from the group.
The diving industry has attempted to provide some basic solutions to some of these challenges. Some scuba divers may customarily carry a knife which could free a diver if he or she is caught in an obstacle. However, not all scuba divers carry a knife, and some obstacles may be too tough for a scuba diver to cut through. Likewise, scuba divers may communicate with each other using hand signals to overcome the lack of voice communication. However, scuba divers may not always be able to see each other due to poor visibility or not being in the same line of sight.
Beyond knives and hand signals, the diving industry has attempted to develop more sophisticated signaling devices. For example, a device known as the Scuba-Alert uses sound waves to signal other divers. The Scuba-Alert uses small pulses of compressed air to vibrate a steel disk and generate a “quacking” sound. However, devices like the Scuba-Alert rely on the inflator hose of a scuba system and draw air from the scuba diver's primary source of air in order to operate. This is but one deficiency with the Scuba-Alert and other products like it, which create further hazard because a diver may be in the most peril when his or her air supply is dangerously low.
Another signaling device is known as the Buddy Call. The Buddy Call is battery powered and uses electronics to generate a signal to other divers. However, the Buddy Call's performance is lacking in many respects. For example, since the Buddy Call is electronic, it has a signal range of only 100 feet and a working depth of up to 110 feet, yet scuba divers may reach depths beyond 110 feet and easily become stranded more than 100 feet from their partner or the nearest rescue source. Also, the Buddy Call is bulky and may not be conveniently located on a diver's suit or other equipment to be easily accessed in the event of an emergency. Finally, the Buddy Call also presents the hazard of not operating due to loss of battery power, which is often undetectable until the device is needed.
Therefore, it would be advantageous to have a more sophisticated signaling device which is independent of a scuba system, has a signal range beyond 100 feet, and a working depth of up to 250 feet. Other advantages over the prior art will become known upon review of the Summary of the Invention and Detailed Description and the appended claims.
In one embodiment of the present disclosure, an underwater signaling device uses its own independent source of pressurized gas to generate sound waves and gain the attention of other divers. The device may have a metal container for a body, and within the container a vessel may store pressurized gas as an independent source of pressurized gas. Because the pressurized gas is stored in a discrete vessel, the underwater signaling device does not tap into the regulator hose of a scuba system and draw air from a scuba diver's primary source of air. Therefore, unlike prior gas-operated signaling devices, the present disclosure operates regardless of the status of the scuba diver's regular air supply.
Further, the present disclosure generates sound waves which can be heard beyond 100 feet, and the present disclosure may operate to a working depth of up to 250 feet. In one embodiment, a puncture pin is located above the pressurized vessel, and a diver may activate a trigger mechanism to puncture the pressurized vessel, releasing the pressurized gas. In one embodiment of the present disclosure, a diver may activate the trigger mechanism by depressing a button located on top of the container such that the diver's own energy is pushing the puncture pin into the vessel. Once the vessel has been punctured, the pressurized gas flows upward and out of a tube which may extend laterally from the body of the container. Within this tube is a sounding device, such as a metal disk, which generates sound waves. The metal disk vibrates when the pressured vessel is punctured and generates sound waves as air moves past it. Beyond the tube, a frusto-conical element may be provided to amplify the sound waves so they may be heard by another diver who is over 100 feet away.
An embodiment of the present disclosure which uses metal materials may operate at increased depths. The container, vessel, and trigger mechanism may be constructed from a variety of metals. Therefore, the present disclosure could be operable to depths of up to 250 feet. This is a marked improvement in performance over electronic signal devices like the Buddy Call, which can only operate to a depth of up to 110 feet.
In a further embodiment, a light strobe or LED or other illumination source may be attached to the exterior of the container of the underwater signaling device. The same trigger mechanism which releases the pressurized gas from the vessel may also activate a light strobe to generate a light signal which complements the sound signal by way of a limit switch, presence sensor or other known input device. The light strobe may be useful in unexpected situations when the sound signal alone is insufficient to direct a second diver to the location of a distressed diver. For example, a second diver may not be able to easily locate a distressed diver if they are not in the same line of sight or there is poor visibility or if the sound signal is bouncing off rocks or coral in the vicinity of the diver, thereby creating an echo effect. The sound signal may alert the second diver and provide the second diver with a general direction where he or she may find the distressed diver. As the second diver travels toward the sound signal, the light strobe may help the second diver by providing a more precise location of the distressed diver.
In a similar vein, a GPS device may be used alone or with any embodiments of the present disclosure described herein, to provide an additional signal for other divers or a dive master or emergency personnel to find a distressed diver. The GPS device may provide a beacon which may be received by a divemaster located on a boat or land, as well as any other receiver which may received a GPS beacon such as a smart phone device. The receiver of such a signal may deploy a boat over the GPS beacon and deploy a diver.
In another embodiment of the disclosure, a diver may pull a rip cord to activate the trigger mechanism. In this embodiment, the trigger mechanism and puncture pin do not derive the energy to puncture the pressurized vessel from the user. Instead, a coiled spring rests behind the puncture pin. When a diver pulls the rip cord, the coiled spring is allowed to release, driving the puncture pin into the pressurized vessel and releasing the contents of the vessel.
Generally, the present disclosure may be attached to a diver in a variety of fashions. In one embodiment, an eyelet may be interconnected to the exterior wall of the container. A half-ring or any other connection component may be partially interconnected to the eyelet such that the ring or component may rotate freely. This eyelet-ring combination allows a diver to attach the present disclosure anywhere on a diver's buoyancy compensator.
Beyond eyelets, the present disclosure may be attached to a diver by other techniques, e.g. straps. A diver's gear may already provide straps such as the waist strap of the buoyancy compensator. Or the present disclosure may include straps which are independent of a diver's existing gear.
A person who is skilled in the art may appreciate techniques to attach the present disclosure to a diver beyond eyelets and straps. For example, the present disclosure may be integrated into a diver's suit. The present disclosure could be woven into a waist pouch.
In another embodiment of the present disclosure, the signaling device may interface with a device on a diver's arm such as a wrist clip, diving computer, amulet, diving watch, or any other component which may activate or send a communiqué to the present disclosure. In this embodiment, a diver may activate the signaling device using the same hand that has an additional device attached. Therefore, if a diver has one arm which is entangled or otherwise encumbered, then the diver may activate the present disclosure using his or her free arm which has a wrist clip, diving computer, amulet, diving watch, or any other component which may activate or send a communiqué to the present disclosure.

The present disclosure is set forth in various levels of detail in the Summary of the Invention as well as in the attached drawings and the Detailed Description of the Invention and no limitation as to the scope of the present disclosure is intended by either the inclusion or non-inclusion of elements, components, etc. in this Summary of the Invention. Additional aspects of the present disclosure will become more readily apparent from the Detailed Description, particularly when taken together with the drawings.
The above-described benefits, embodiments, and/or characterizations are not necessarily complete or exhaustive, and in particular, as to the patentable subject matter disclosed herein. Other benefits, embodiments, and/or characterizations of the present disclosure are possible utilizing, alone or in combination, as set forth above and/or described in the accompanying figures and/or in the description herein below.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the disclosure and together with the general description of the disclosure given above and the detailed description of the drawings given below, serve to explain the principles of the disclosures.
It should be understood that the drawings are not necessarily to scale. In certain instances, details that are not necessary for an understanding of the disclosure or that render other details difficult to perceive may have been omitted. It should be understood, of course, that the disclosure is not necessarily limited to the particular embodiments illustrated herein.
In the drawings:
The subject of the present disclosure relates to an underwater signaling device which has advantages over gas-operated devices and electronic devices. In one embodiment of the present disclosure, the component materials are made of metal, which allows for greater resistance to water pressure as the depth of operation increases. However, a person who is skilled in the art may identify another material, or materials, which is advantageous for operation depth or other parameters.
As described in detail below, various embodiments of the present disclosure comprise a novel valve, further comprising an inlet connection and an outlet connection, each connection further comprising a horizontal and vertical adjustment means, and/or other features.
The bottom wall 102 interconnects or selectively interconnects with at least one upwardly-extending lower wall 103. Within a portion of this wall 103 is a vessel 110 which contains pressurized gas. This vessel 110 is advantageous because the source of air for the underwater signaling device 101 is independent of the diver's air supply. Further, the vessel 110 may be configured or designed to be punctured, releasing the pressurized gas.
Continuing upward, one particular embodiment of the present disclosure has an upwardly-extending, frusto-conical wall 104 interconnected to the at least one upwardly-extending lower wall 110. The frusto-conical wall 104 tapers to a smaller diameter. At least one upwardly-extending upper wall 105 is interconnected with the frusto-conical wall 104. Finally, a substantially planar top wall 106 is interconnected with the at least one upwardly-extending upper wall 105.
The aforementioned elements of this particular embodiment of the present disclosure form a basic container of the underwater signaling device 101 which contains a vessel 110 for holding and selectively releasing a pressurized gas.
Various embodiments of the present disclosure may puncture the vessel 110 in order to release its pressurized gas. The trigger mechanism 115 with a puncture pin 118 is substantially positioned inside of the container and above the vessel 110. A portion of the trigger mechanism 115 extends upward through an opening 107 in the top wall 106 such that a user may depress this extended portion to activate the trigger mechanism 115. A guide plate 114 may keep the trigger mechanism substantially vertical, and the guide plate 114 provides a surface for the spring 116 to compress against. The spring 116 presents an upward force against the trigger mechanism 115 to keep the puncture pin 118 away from the vessel 110 before the trigger mechanism 115 is activated. When a user depresses the trigger mechanism 115, the puncture pin 118 punctures the vessel 110 and releases the pressurized gas.
A laterally extending tube 111 is interconnected to at least one upwardly-extending upper wall 105 such that the tube 111 communicates with the interior of the underwater signaling device 101. Within the tube 111 is a metal disk 113 or similar device which vibrates as pressurized gas rushes over it. When the pressurized gas is released from the vessel 110, it rushes out of the laterally extending tube 111. The vibrating metal disk 113 generates sound waves which travel out of the laterally extending tube 111. A second, frusto-conical wall 112 may be interconnected to the laterally extending tube 111. This frusto-conical wall 112 may amplify the sound waves generated by the vibrating metal disk 113.
Various embodiments of the present disclosure may attach to a user's body or gear. An eyelet may be interconnected to the at least one upwardly-extending lower wall 103. In this particular embodiment, a half ring 109 is partially interconnected with the eyelet 108 such that the half-ring may freely rotate. This half ring 109 may attach to the user or diver via a carabiner on the diver's gear.
In a further embodiment, a person who is skilled in the art may appreciate additional components to the underwater signaling device 101 which enhance or complement the devices' audible signal. For example, an embodiment of the present disclosure may have a light strobe which is interconnected to the at least one upwardly-extending lower wall 103. A light strobe may be an advantageous complement to the audible signal since a second diver may not be able to immediately locate the distressed diver with the audible signal. A light strobe component would help a second diver precisely locate a distressed diver.
In yet another embodiment of the present disclosure, a GPS device may be used alone, or with any embodiments of the present disclosure provided herein, to provide an additional signal for other divers to find a distressed diver. The GPS device may be interconnected to the first upwardly-extending wall 103 of the underwater signaling device 101. The GPS device may provide a beacon which may be received by a divemaster located on a boat or land, as well as any other receiver which may received a GPS beacon such as a smart phone device. The receiver of such a signal may deploy a boat over the GPS beacon and deploy a diver.
