Aeration fitting for an aquarium

Abstract

An aeration fitting for an aquarium including a hollow outer fitting having an interior channel, a cylindrical back portion, a cylindrical front portion having a threaded outer surface, a tapered cylindrical middle portion, and a frontwardly flared outer lip. A floating ball is disposed within the interior channel of the outer fitting. A hollow inner fitting has an inner channel, a cylindrical posterior portion, a cylindrical anterior portion having a threaded inner surface, a tapered cylindrical central portion, and a frontwardly flared inner lip. A spring is disposed within the inner channel of the inner fitting. Each of the back portion of the outer fitting and the posterior portion of the inner fitting is connectable to an air hose, and the threaded outer surface of the front portion is selectively engageable with the threaded inner surface of the anterior portion within an aperture in a wall of an aquarium.

Claims

1. An aeration fitting for an aquarium comprising: a single continuous hollow outer fitting having a single continuous interior channel, a cylindrical back portion, a cylindrical front portion having a threaded outer surface, a tapered cylindrical middle portion disposed between the back portion and the front portion, and a frontwardly flared outer lip continuously disposed around an entirety of a circumference of the outer fitting between the middle portion and the front portion, wherein each of the back portion, the front portion, and the middle portion have a front end and back end; wherein a diameter of the back portion of the outer fitting is greater than a diameter of the back end of the middle portion of the outer fitting; wherein the diameter of the back end of the middle portion of the outer fitting is less than a diameter of the front end of the middle portion of the outer fitting; wherein a diameter of the interior channel of the outer fitting proximal the front end of the front portion is greater than a diameter of the interior channel of the outer fitting proximal the back end of the back portion; a floating ball moveably disposed within the interior channel of the outer fitting proximal the front end of the front portion; a single continuous hollow inner fitting having a single continuous inner channel, a cylindrical posterior portion, a cylindrical anterior portion having a threaded inner surface, a tapered cylindrical central portion disposed between the posterior portion and the anterior portion, and a frontwardly flared inner lip continuously disposed around an entirety of a circumference of the inner fitting between the central portion and the anterior portion, wherein each of the posterior portion, the anterior portion, and the central portion has an anterior end and a posterior end; wherein a diameter of the posterior portion of the inner fitting is greater than a diameter of the posterior end of the central portion of the inner fitting; wherein the diameter of the posterior end of the central portion of the inner fitting is less than a diameter of the anterior end of the central portion of the inner fitting; wherein a diameter of the inner channel of the inner fitting proximal the anterior end of the anterior portion is greater than a diameter of the inner channel of the inner fitting proximal the posterior end of the posterior portion; and a spring disposed within the inner channel of the inner fitting proximal the anterior end of the anterior portion; wherein each of the back portion of the outer fitting and the posterior portion of the inner fitting is removably connectable to an air hose; wherein the inner lip of the inner fitting is removably disposed on an interior surface of a wall of an aquarium and the outer lip of the outer fitting is removably disposed on an exterior surface of the wall of the aquarium; wherein each of the anterior portion of the inner fitting and the front portion of the outer fitting is disposed within an aperture disposed through the wall of the aquarium such that the threaded outer surface of the front portion is selectively engageable with the threaded inner surface of the anterior portion within the aperture; wherein the air hose connected to the back portion of the outer fitting is configured to be connectable to an air pump in order to transport air from the outer fitting through the inner fitting disposed within the aquarium.

2. The aeration fitting for an aquarium of claim 1 wherein a diameter of the floating ball is 0.125 inches.

DETAILED DESCRIPTION OF THE DRAWINGS

(7) With reference now to the drawings, and in particular FIGS. 1 through 6 thereof, an example of the instant aeration fitting for an aquarium employing the principles and concepts of the present aeration fitting for an aquarium and generally designated by the reference number 10 will be described.

(8) Referring to FIGS. 1 through 6 the present aeration fitting for an aquarium 10 is illustrated. The aeration fitting for an aquarium 10 includes a single continuous hollow outer fitting 20 having a single continuous interior channel 22, a cylindrical back portion 24, a cylindrical front portion 26 having a threaded outer surface 28, a tapered cylindrical middle portion 30 disposed between the back portion 24 and the front portion 26, and a frontwardly flared outer lip 32 continuously disposed around an entirety of a circumference of the outer fitting 20 between the middle portion 30 and the front portion 26. Each of the back portion 24, the front portion 26, and the middle portion 30 have a front end 34 and back end 36. A floating ball 38 is moveably disposed within the interior channel 22 of the outer fitting 20 proximal the front end 34 of the front portion 26.

(9) A single continuous hollow inner fitting 40 has a single continuous inner channel 42, a cylindrical posterior portion 44, a cylindrical anterior portion 46 having a threaded inner surface 48, a tapered cylindrical central portion 50 disposed between the posterior portion 44 and the anterior portion 46, and a frontwardly flared inner lip 52 continuously disposed around an entirety of a circumference of the inner fitting 40 between the central portion 50 and the anterior portion 46, wherein each of the posterior portion 44, the anterior portion 46, and the central portion 50 has an anterior end 54 and a posterior end 56. A spring 58 is disposed within the inner channel 42 of the inner fitting 40 proximal the anterior end 54 of the anterior portion 46.

(10) Each of the back portion 24 of the outer fitting 20 and the posterior portion 44 of the inner fitting 40 is removably connectable to an air hose 60. The inner lip 52 of the inner fitting 40 is removably disposed on an interior surface 62 of a wall of an aquarium 64 and the outer lip 32 of the outer fitting 20 is removably disposed on an exterior surface 66 of the wall of the aquarium 64. Each of the anterior portion 46 of the inner fitting 40 and the front portion 26 of the outer fitting 20 is disposed within an aperture 68 disposed through the wall of the aquarium 64 such that the threaded outer surface 28 of the front portion 26 is selectively engageable with the threaded inner surface 48 of the anterior portion 46 within the aperture 68. The air hose 60 connected to the back portion 24 of the outer fitting 20 is configured to be connectable to an air pump 70 in order to transport air from the outer fitting 20 through the inner fitting 40 disposed within the aquarium.
