Disposable floating flashlight

Claim 2

A floating electric flashlight including a sealed water-resistant casing defining a flotation chamber and including an air chamber portion at each end of said casing having substantially equal volumes of air confined therein for maintaining and balancing the flotation of said flashlight in a predetermined orientation when placed in water, electrical energy producing storage means for providing a source of electrical energy and an electrically energizable light bulb carried within said casing,

Claim 3

said storage means and said light bulb coupled into an electrical circuit for connecting the electrical energy from said storage means to said light bulb for effecting the illumination thereof, and normally open switch means carried entirely within said casing, and coupled into said electrical circuit and operable into a closed position upon flexing said casing for coupling the electrical energy from said storage means to said light bulb thereby effecting the illumination thereof.

Claim 4

said storage means and said light bulb coupled into an electrical circuit for connecting the electrical energy from said storage means to said light bulb for effecting the illumination thereof, and normally open switch means carried entirely within said casing, and coupled into said electrical circuit and operable into a closed position upon flexing said casing for coupling the electrical energy from said storage means to said light bulb thereby effecting the illumination thereof.

Claim 5

The apparatus of claim 1 wherein a portion of said light bulb carried within said casing extends outwardly therefrom to direct a light beam emanated thereby.

Claim 6

The apparatus of claim 1 wherein said casing comprises a resilient electrically insulating material.

Claim 7

The apparatus of claim 1 wherein said electrical energy producing storage means comprises at least first and second electrically coupled batteries carried within said case, each of said batteries having an electrically conducting can acting as one terminal thereof and a terminal post acting as a second terminal of opposite electrical polarity and electrically isolated from said can, said electrically energizable light bulb includes a pair of electrical terminals, each one of said terminals being mutually exclusively electrically coupled to a terminal of opposite polarity of each of said batteries, and said normally open switch means carried entirely within said casing comprises a resilient electrically conducting cantilevered switch wire having one end electrically coupled to and supported from one terminal of one of said batteries, and an opposite free end extending to a position normally adjacent to and spaced from a terminal of opposite polarity of the other of said batteries.

Claim 8

The apparatus of claim 4 wherein said resilient electrically conducting cantilevered switch wire is carried adjacent said casing such that said switch wire is closed into electrical contact with said adjacent normally spaced battery terminal to illuminate said flashlight bulb upon the flexing of said casing.

Claim 9

The apparatus of claim 4 wherein one end of said resilient electrically conducting cantilevered switch wire is secured to the terminal post of said first electrically coupled battery, and the free end thereof extends to a position adjacent to but spaced from the electrically conducting can of said second electrically coupled battery, such that upon flexual movement of said casing said resilient electrically conducting cantilevered switch wire will close said electrical circuit for illuminating said light bulb.

Claim 10

The apparatus of claim 4 wherein the electrical terminals of said electrically energizable light bulb comprise first and second flexible electrical conductive leads, said first electrically conductive lead being secured to the can of said first electrically coupled battery, and said second electrically conductive lead being secured to the terminal post of said second electrically coupled battery.

Claim 11

The apparatus of claim 4 wherein said sealed, water-resistant casing extends a length greater than said batteries and said batteries are positioned intermediate the ends of said casing to thereby define two air-retaining chambers extending between each end of the batteries and the end of said casing.

Claim 12

The apparatus of claim 8 further including phosphorescent material carried within said flotation chamber such that upon illumination of said light bulb said phosphorescent material will luminesce.

Claim 13

The apparatus of claim 9 wherein a portion of said light bulb is positioned within one of said-retaining chambers positioned contiguous the ends of said batteries to define a regeneration chamber for regenerating the phosphorescence of said luminescent material upon energization of said light bulb.

Claim 14

The apparatus of claim 10 wherein said other air-retaining chamber portion opposite to said regeneration chamber forms a balancing air chamber and contains an electrically insulating spacer for preventing movement of said batteries within said casing.

Claim 15

The apparatus of claim 11 wherein said regeneration chamber and said balancing air chamber contain substantially equal quantities of air for maintaining said flashlight in a predetermined orientation when placed in water.
