Compartment Drain Strainer

Abstract

A device for allowing a user to adjust drainage properties of a sink drain is disclosed, comprising an inner tube inserted into a stopper ring. The stopper ring is inserted into the drain such that liquids cannot enter the sink drain except by traversing the inner tube. An outer tube is fitted substantially completely around the inner tube. A selector slot of the outer tube may be aligned with a selected drain slot of the inner tube to allow draining of the sink down to a lower height of an exposed drain slot of the inner tube. A straining tube is adapted to fit loosely around the outer tube and has a plurality of straining apertures each no larger than a predetermined size. The apertures are formed along the entire length of the straining tube. With the straining tube placed around the outer tube, debris having a size larger than the predetermined size is prevented from flowing through the slots of the outer and inner tubes and into the sink drain.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not Applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT[0002]Not Applicable.FIELD OF THE INVENTION[0003]This invention relates to sink drains, and more particularly to a device for allowing easy adjustment of drainage properties of a sink drain.DISCUSSION OF RELATED ART[0004]Numerous innovations for sink drain devices have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.[0005]A first example, U.S. Pat. No. 3,895,401, issued on Jul. 22, 1975, to Walraven teaches a drain structure connecting a sink with a waste line. The entire drain structure is outside the horizontally projected extent of the sink so as to optimize the capacity of the sink. A vertically extending screen extending upwardly from the bottom of the sink is substantially coplanar with one sidewa...

Benefits of technology

[0014]Another object of the present invention is to provide an adjustment device for a sink drain that is simple and inexpensive to manufacture.

[0015]Still another object of the present invention is to provide an adjustment device for a sink drain that is simple to use.

[0016]Briefly stated, still yet another object of the present invention is to provide an adjustment device for a sink drain that comprises an inner tube inserted into a stopper ring. The stopper ring is inserted into the drain such that liquids cannot enter the sink drain except by traversing the inner tube. An outer tube is fitted substantially completely around the inner tube. A selector slot of the outer tube may be aligned with a selected drain slot of the inner tube to allow draining of the sink down to a lower height of an exposed drain slot of the inner tube. A straining tube is adapted to fit loosely around the outer tube, and has a plurality of straining apertures each no larger than a predetermined size. The apertures are formed along the entire length of the straining tube. With the straining tube placed around the outer tube, debris having a size larger than the predetermined size is prevented from flowing through the slots of the outer and inner tubes and into the sink drain.

Problems solved by technology

One drawback with this type of sink drain device is that it cannot be easily retrofitted with existing sinks.

Such a device also suffers from the drawback that it cannot be easily integrated with existing sinks.

One drawback with this type of sink drain device is that it does not provide for easily-selectable and distinct water levels.

This type of device also does not provide for easily-selectable and distinct water levels.

This type of device also does not provide for easily-selectable and distinct water levels.

This type of device also does not provide for easily-selectable and distinct water levels.

None of the aforementioned prior art sink drain devices teaches an adjustment device for a sink drain which includes a rotatable outer tube to help facilitate the drainage of water at different levels through the sink drain.
