Diffuser and anchor
View Patent ↗An aquarium aerator unit includes an anchor that is weighted by an aquarium bedding material. The anchor includes a lower portion that has a defined edge and spaced-apart side sections proximate to the lower portion. An inner space is formed between the side sections above the lower portion. The defined edge provides a shovel edge that eases the lower portion into the bedding material and the inner space storing the bedding material to enhance stability and aesthetics.
1. An aquarium aerator unit comprising:
an anchor weighted by an aquarium bedding material, the anchor comprising
a lower portion comprising a shovel edge,
spaced-apart side sections proximate to the lower portion,
an upright portion joined to each side section by a respective cross-bar and joined to the lower portion by a vertical bar, the
an inner space formed between the side sections above the lower portion and having at least two through-openings;
a diffuser for passing air and secured in the anchor, the diffuser comprising a stem that passes through a plane of the anchor to connect to an air line;
wherein the shovel edge eases the lower portion into the bedding material and the inner space storing the bedding material to enhance stability and aesthetics.
2. The aquarium aerator unit of claim 1 , wherein the lower portion comprises a curve in a longitudinal direction.
3. The aquarium aerator unit of claim 1 , wherein the inner space narrows distal from the defined edge for easier grasping by a user.
4. The aquarium aerator unit of claim 1 further comprising a diffuser angled approximately 45 degrees with respect to the lower portion.
5. The aquarium aerator unit of claim 1 further comprising a second anchor, the diffuser supported by the anchors.
6. The aquarium aerator unit of claim 5 , wherein each of the anchors comprises a receiving portion for receiving ends of the diffuser.
7. The aquarium aerator unit of claim 5 further comprising a third anchor and a second diffuser supported by the second and third anchors.
8. The aquarium aerator unit of claim 7 , wherein one of the anchors comprises a receiving portion that is configured to receive two diffusers.
9. The aquarium aerator unit of claim 8 , wherein the receiving portion is configured to communicate pressurized air from one to diffuser to another diffuser.
10. The aquarium aerator unit of claim 1 , wherein the diffuser comprises an epoxy resin compound.
11. The aquarium aerator unit of claim 1 , wherein the anchor is integrally constructed.
12. The aquarium aerator unit of claim 1 , wherein the anchor comprises a center portion having a vertical bar and two openings, one opening at each side spacing the vertical bar from the side sections.
13. The aquarium aerator unit of claim 1 , wherein the anchor comprises a center section having a U-shaped portion for receiving the diffuser.
14. The aquarium unit of claim 1 , wherein the anchor comprises a longitudinal length that is less than one-fourth of a longitudinal length of the diffuser.
15. An aquarium aerator unit comprising:
a plurality of anchors weighted by an aquarium bedding material, each anchor comprising
a lower portion comprising a shovel edge, spaced-apart side sections proximate to the lower portion, an upright portion joined to each side section by a respective cross-bar and joined to the lower portion by a vertical bar, an inner space formed between the side sections above the lower portion and having at least two through-openings;
a diffuser for passing air and supported by the anchors; wherein the shovel edge eases,
the lower portion into the bedding material and the inner space storing the bedding material to enhance stability and aesthetics;
wherein the anchors are spaced apart from each other by a length of at least ¾ of a longitudinal length of the diffuser.
16. The aquarium aerator unit of claim 15 , wherein at least one anchor comprises a center section having a U-shaped portion for receiving the diffuser.
17. The aquarium aerator unit of claim 15 , wherein at least one anchor comprises a center portion having a vertical bar and two openings, one opening at each side spacing the vertical bar from the side sections.
