The present invention relates generally to sinks, and more particularly, to a plug for a sink overflow configured to block the flow of air when plunging a main drain.
There is no other plumbing task more appalling than having to deal with clogged drain piping. Many people turn to the use of chemical drain cleaners, but such cleaners are hazardous to store, especially with children and pets around. They can also be dangerous to the piping and sink surfaces as well. Finally, they may pose environmental dangers as they are flushed out of the pipe, and onto wastewater treatment facilities.
Others turn to the use of mechanical systems, most commonly a plunger. While such plungers do a great job, they are somewhat ineffective on sinks with an overflow opening, such as a bathroom sink. This is because any positive or negative pressure generated by the plunger escapes out of the overflow, rather than being directed to the clog. Users often use rags or even their hands to cover the openings, but they are not completely airtight.
Accordingly, there exists a need for a means by which overflow openings in sink drains can be completely and securely covered, in order to prevent the problems as described above.
The inventor has recognized the aforementioned inherent problems and lack in the art and observed that there is a need for a device configured to completely and securely cover overflow openings on sink drains during plunging operations. The development of the present invention, which will be described in greater detail herein, substantially departs from conventional solutions to provide a sink overflow hole plug and in doing so fulfills this need.
In one (1) embodiment, the disclosed sink overflow hole plug can include a plug body defining an interior chamber, and at least one protuberance extending into the chamber, wherein the protuberance is configured to be received by an external aperture of an overflow prevention channel of a drainage system of a plumbing fixture.
In another embodiment, the disclosed sink overflow hole plug can include a plug body including a continuous sidewall including an upper perimeter edge and a lower perimeter edge and a diaphragm connected to the upper perimeter edge of the sidewall, the sidewall and the diaphragm defining an interior chamber, the lower perimeter edge of the sidewall being open to provide access to the chamber, and at least one protuberance extending from an interior surface of the diaphragm into said chamber, wherein the protuberance is configured to be received by an external aperture of an overflow prevention channel of a drainage system of a plumbing fixture.
Furthermore, the described features and advantages of the disclosed sink overflow hole plug can be combined in various manners and embodiments as one skilled in the relevant art will recognize after reading the present disclosure. The disclosure can be practiced without one (1) or more of the features and advantages described in any particular embodiment.
Further advantages of the present disclosure will become apparent from a consideration of the drawings and ensuing description.
The advantages and features of the present disclosure will become better understood with reference to the following more detailed description and claims taken in conjunction with the accompanying drawings, in which like elements are identified with like symbols, and in which:
In accordance with the invention, the best mode is presented in terms of the described embodiments, herein depicted within
It can be appreciated that, although such terms as first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one (1) element from another element. Thus, a first element discussed below could be termed a second element without departing from the scope of the present invention. In addition, as used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It also will be understood that, as used herein, the term “comprising” or “comprises” is open-ended, and includes one (1) or more stated elements, steps or functions without precluding one (1) or more unstated elements, steps or functions. Relative terms such as “front” or “rear” or “left” or “right” or “top” or “bottom” or “below” or “above” or “upper” or “lower” or “horizontal” or “vertical” may be used herein to describe a relationship of one (1) element, feature or region to another element, feature or region as illustrated in the figures. It should be understood that these terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. It should also be understood that when an element is referred to as being “connected” to another element, it can be directly connected to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” to another element, there are no intervening elements present. It should also be understood that the sizes and relative orientations of the illustrated elements are not shown to scale, and in some instances they have been exaggerated for purposes of explanation.

The body 20 of the device 10 can include an encircling wall 21 terminating at the top in a diaphragm 22 in such a way as to form (e.g., define) a chamber 24. The body 20 can be configured in any shape, such as an oval shape, a round shape, or any other appropriate shape, without limitation. Disposed upon an interior surface of the diaphragm 22 and extending inwardly inside of the chamber 24 is at least one (1) tapered protuberance 26. For example, the body 20 can include three (3) protuberances 26. The protuberances 26 can be configured to be inserted into and block each external aperture 102 of the overflow prevention channel 101 of the plumbing fixture 100 (
The total quantity of protuberances 26 in the body of the device 10 can depend upon the number of external apertures 102 that exist in the plumbing fixture 100. Consequently different embodiments of the device 10 can include a different number of protuberances 26 without limitation. In those embodiments where a plurality of protuberances 26 exist, the protuberances 26 can be positioned to align with the external apertures 102 of the plumbing fixture 100. For example, the protuberances 26 can be positioned uniformly distributed along the centerline of the major axis of the body 20.
A lip 28 can be circumferentially disposed at the bottom of the encircling wall 21. The lip 28 can include a thickness greater than the thickness of the wall 21. The lip 28 can be connected to or integral to the perimeter edge of the wall 21. A groove 29 can be circumferentially disposed around the lip 28. For example, the groove 29 can be molded within the lip 28 (

It is envisioned that other styles and configurations of the disclosed device 10 can be easily incorporated into the teachings of the present disclosure, and only certain particular configurations have been shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
In an example implementation, a user can utilize the example embodiments of the device 10 in a simple and straightforward manner with little or no training. After initial purchase or acquisition of the device 10, it can be installed as indicated in
An example method of installing and utilizing the device 10 can be achieved by performing the following steps: acquiring a model of the device 10 having the desired configuration to match the external apertures 102 in the plumbing fixture 100; aligning the protuberance 26 (or protuberances 26 depending upon the configuration of the device 10) in the chamber 24 of the device 10 with the external aperture 102 (or apertures 102) in the plumbing fixture 100; depressing the diaphragm 22 to force the protuberances 26 into the external apertures 102 until the lip 28 comes into contact with the plumbing fixture 100; continuing to depress the diaphragm 22 until the wall 21 of the device 10 buckles and the protuberances 26 are engaged into the external apertures 102 to the extent that an interference fit is established between the protuberances 26 and the external apertures; and continuing to press against the device 10 (e.g., with the fingers of a user's hand engaged into the indentations 23 in the diaphragm 22) while using an opposing hand to use a plunger, or other pressure or vacuum device, to remove material that interferes with the normal functioning of the drainage system.
The foregoing embodiments of the disclosed sink overflow hole plug have been presented for purposes of illustration and description.
