DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new retrieval device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 5, the underwater object retrieval device 10 generally comprises an inflation unit 12 that is configured to inflate upon command. More specifically, the inflation unit 12 comprises a bag 14 that is selectively inflatable. A safety valve 16 is positioned through and coupled to a wall 18 of the bag 14. The safety valve 16 is positioned in the wall 18 such that the pressure in the bag 14 does not exceed a pressure allowed by the safety valve 16. A deflater 20 is positioned in and coupled to the wall 18 of the bag 14. The deflater 20 is positioned in the wall 18 such that the bag 14 is deflatable. Preferably, the deflater 20 comprises a resealable opening 22 positioned in the wall 18.
A housing 24, which is watertight, is coupled to the bag 14. Preferably, the housing 24 is substantially rectangularly box shaped. A power storage module 26 is positioned in and coupled to the housing 24. Preferably, the power storage module 26 comprises at least one battery 28. An actuator 30 is positioned in and coupled to the housing 24. The actuator 30 is fluidically coupled to the bag 14 and operationally coupled to the power storage module 26. An effector unit 32 is coupled to the housing 24. Preferably, the effector unit 32 is coupled to an upper face 34 of the housing 24. The effector unit 32 is operationally coupled to the actuator 30, such that the effector unit 32 is positioned to motivate the actuator 30.
In one embodiment of the invention, the effector unit 32 comprises a timer 36. The timer 36 is operationally coupled to the actuator 30. The timer 36 is configured to be set by the user such that the timer 36 motivates the actuator 30 at a preset time. In another embodiment, the effector unit 32 comprises a receiver 38 and a transmitter 40. The receiver 38 is coupled to the housing 24 and operationally coupled to the actuator 30. The transmitter 40 is wirelessly coupled to the receiver 38. The transmitter 40 is positioned to signal the receiver 38 to motivate the actuator 30.
A reservoir 42 is sealably and fluidically couplable to the actuator 30. The reservoir 42 is configured for storage of compressed gas. Preferably, the reservoir 42 comprises a tank 44. The tank 44 comprises a cylinder 46 that has opposing ends 48, which preferably are rounded. A neck 50 is coupled to a respective opposing end 48. The neck 50 is threaded, such that the neck 50 is threadedly couplable to the actuator 30.
The device 10 comprises a coupler 52 and a tether line 54. The coupler 52 is configured for coupling to an object to be placed underwater. The tether line 54 has a first end 56 and a second end 58. The first end 56 is coupled to the inflation unit 12 and the second end 58 is coupled to the coupler 52. Preferably, the coupler 52 comprises a clip 60. The clip 60 comprises a loop end 62 and a snap end 64. The loop end 62 is positioned to couple to the second end 58 of the tether line 54 and the snap end 64 is configured for attachment to the object to be placed underwater.
A line storage unit 66 is coupled to the tether line 54 proximate to the second end 58. The line storage unit 66 is positioned to house the tether line 54, such that the tether line 54 is extensible from the line storage unit 66. Preferably, the line storage unit 66 comprises a spool 68. The spool 68 comprises a hub 70 and a pair of flanges 72. The hub 70 is substantially cylindrically shaped and has opposing endpoints 74. Each flange 72 is coupled to the hub 70 proximate to a respective opposing endpoint 74. The hub 70 is positioned for winding of the tether line 54, such that the tether line 54 is retained around the hub 70 between the flanges 72.
The tether line 54 may comprise a first segment 75 and a second segment 76. The first segment 75 comprises the first end 56 of the tether line 54 and a first terminus 77. The first terminus 77 is coupled to the line storage unit 66. The second segment 76 comprises the second end 58 of the tether line 54 and a second terminus 78. The second terminus 78 is coupled to the line storage unit 66.
In use, the inflation unit 12 is coupled using the coupler 52 to the object to be placed underwater for later recovery. The timer 36 may be used to set a time point when the actuator 30 will be engaged. Alternatively, the user may employ the transmitter 40 to signal the receiver 38 to motivate the actuator 30. The actuator 30 is coupled to the reservoir 42, which contains a compressed gas such as carbon dioxide. Upon motivation by the effector unit 32, the actuator 30 motivates gas to expand into the bag 14. The bag 14 becomes buoyant and induces the tether line 54 to unspool from the spool 68 until the bag 14 reaches the surface. The tether line 54 is configured for retrieving the object to the surface.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
