Abstract
A float apparatus for preventing the loss of a bow accidentally dropped in a body of water, the apparatus including a hydrostatic valve, a camshaft, a plunger, a gas cartridge and a bladder, all of which are operatively coupled to one another by a valve frame contained within a housing. When a bow having the float apparatus attached thereto is submerged, the hydrostatic valve automatically rotates the camshaft when the float apparatus reaches a desired depth. As the camshaft rotates, it presses against the plunger causing it to pierce the gas cartridge thereby releasing a gas. The gas is then directed through the valve frame into the bladder thereby inflating the bladder and causing the bow to float.
Claims23
A float apparatus, comprising:
- a housing configured for attachment to a bow, the housing containing a hydrostatic valve member, a camshaft operatively coupled to the hydrostatic valve, a plunger operatively coupled to the camshaft, a gas cartridge operatively coupled to the plunger, and a bladder operatively coupled to the gas cartridge.
A float apparatus comprising:
- a. a valve frame configured for attachment to a bow, the valve frame including;
- b. a camshaft receiving portion;
- c. a hydrostatic valve receiving member portion connected to said camshaft receiving portion;
- d. a gas cartridge receiving portion having a gas inlet;
- e. a bladder receiving portion having a gas outlet;
- and,
- f. a gas passageway extending to and between the gas inlet and the gas outlet.
A bow comprising:
- a. a source of gas;
- b. an inflatable bladder;
- and,
- c. a mechanism configured for selectively releasing a gas from the source of gas when the bow is submerged in a liquid and directing the gas into the inflatable bladder, said releasing mechanism including a hydrostatic valve and a camshaft within a housing for triggering said mechanism.
A method of retrieving a bow from a body of water comprising:
- a. submerging the bow in a body of water;
- b. triggering a release mechanism with a hydrostatic valve connected to a camshaft;
- c. responsive to movement of said camshaft, releasing gas from a source of gas attached to the bow when the bow is at or below a desired depth in the body of water;
- d. directing the gas into the inflatable bladder thereby inflating the inflatable bladder and causing the bow to float upward;
- and,
- e. retrieving the bow after the bow surfaces the body of water.
A bow flotation device, comprising:
- a. housing means for attaching said flotation device to a bow
- b. means within said housing means for providing a hydrostatic valve, wherein said valve means includes a camshaft for rotation thereof responsive to actuation of said valve means;
- c. plunger means operatively coupled to said camshaft;
- d. means operatively coupled to said plunger for providing a gas source;
- and
- e. means for providing an inflatable bag operatively coupled to said gas means, wherein said bag means is configured to inflate from an empty state into an inflated state upon actuation of said gas means.
