Abstract
A water-level indicator and re-fill apparatus for the sub-irrigation of potted plants. The indicator uses a float and shaft placed inside an outer tube attached to a potted plant as a way to visually indicate to the user when the reservoir of the sub-irrigation system is running low. While attached to the plant, the user may conveniently re-fill the apparatus after being notified of the water level without disassembling the apparatus or removing it from a decorative planter.
Claims31
A water-level indicator and refill apparatus for potted plants comprising:
- an outer tube having:
- an upper end and a lower end with said upper end having an opening and said lower end having a lower cap with a plurality of drainage slots;
- a water-level indicator cap having a closed end and an open end, having a dome on said closed end, which is mechanically attached to said outer tube;
- a shaft having a first end and a second end extending longitudinally through said outer tube;
- a float attached to said shaft by a receiving slot;
- and
- a clamping system mechanically attached to said outer tube securing said outer tube to said potted plant.
A water-level indicator and refill apparatus for potted plants comprising:
- a lid having an upper lip and two lower leaves for forming a hinge system;
- an outer tube having:
- an upper end and a lower end with said upper end having an opening and lower lip and said lower end having a lower cap;
- two lower leaves to a hinge system in a U-shape molded into said upper end;
- a molded tab clipped centrally between the two leaves of the hinge system having an aperture;
- a plurality of drainage slots located on said lower cap of said outer tube to provide a point of egress for liquid within the apparatus;
- a hinge system where the upper leaves on the lid slide together with the lowers leaves molded into the outer tube and connect with a hinge pin;
- a water-level indicator cap having a closed end and an open end, having a dome on said closed end, which is mechanically attached to said molded tab;
- a shaft having a first end and a second end extending longitudinally through said outer tube, said shaft having a length longer than the length of said outer tube, wherein said shaft extends through said aperture of said molded tab and through said open end of said water-level indicator cap to a length just beneath the dome of said water-level indicator cap when liquid level in the apparatus is at a maximum and wherein said shaft extends to a length just beyond the open end of said water-level indicator cap when liquid level is at a minimum;
- A float attached to said shaft by a receiving slot;
- and
- A clamping system having two outer arms, two upper arms, two inner arms, and a connecting arm attached to said outer tube by lowering said clamping system in a slot in said outer tube and securing with a hinge pin.
A water-level indicator and refill apparatus for potted plants comprising:
- A lid having an upper lip and two lower leaves for forming a hinge system;
- An outer tube with having:
- A upper end and a lower end with said upper end having an opening and lower lip and said lower end having a lower cap;
- Two lower leaves to a hinge system in a U-shape molded into said upper end;
- A molded tab clipped centrally between the two leaves of the hinge system having an aperture;
- A plurality of drainage slots located on said lower cap of said outer tube to provide a point of egress for liquid within the apparatus;
- A hinge system where the upper leaves on the lid slide together with the lowers leaves molded into the outer tube and connect with a hinge pin;
- A shaft having a first end and a second end extending longitudinally throughout said outer tube, said shaft having a length longer than the length of said outer tube, wherein said shaft extends through said aperture of said molded tab and through said opening of said outer tube to a length beyond the upper end of said outer tube when liquid level in the apparatus is at a maximum and wherein said shaft extends to the same length of said outer tube when liquid level is at a minimum;
- A float attached to said shaft by a receiving slot;
- and
- A clamping system having two outer arms, two upper arms, two inner arms, and a connecting arm attached to said outer tube by lowering said clamping system in a slot in said outer tube and securing with a hinge pin.
