Definitions
- the present invention relates generally to a plumbing apparatus and more specifically, to an apparatus intended for use in unclogging a drain pipe.
- the apparatus enables the user to regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris.
- drain pipes Since the advent of indoor plumbing, drain pipes have experienced clogging. From kitchen and bathroom sinks to tubs and showers, debris proceeding down the drain builds-up or otherwise becomes trapped in certain locations of the drain pipe. The limited diameter of many of these pipes and the complex array of bends and turns associated with the pipes in an indoor plumbing system contribute to the clogging. Once clogged, the sink or other device associated with the clogged drain pipe becomes substantially unusable, thereby requiring user intervention to dislodge or otherwise remove the debris.
- plungers are well known devices for use in attempting to unclog a drain pipe. These devices generally include some form of cup or bellows for supplying bursts of air to the drain pipe. Unfortunately, these devices may only supply a small volume of air to the drain pipe for a very short amount of time. Moreover, these devices fail to adequately seal the drain associated with the clogged drain pipe. This results in air escaping around the cup or bellows during the plunging operation. Therefore, the user must repeat the plunging operation many times and may be unable to build up enough pressure in the drain pipe to displace the clogging debris.
- Other devices incorporate an air pump to direct a burst of air at an elevated pressure into the drain pipe.
- These devices includes a rubber cup that fits over the drain having the clogged drain pipe. Similar to the plunger, this rubber cup fails to properly seal the drain, therein allowing air to escape around the cup and failing to deliver a sufficient volume of air to displace the clog.
- these devices utilize a chamber to build up pressure and a valve actuated by a trigger to release the air. Similar to the plunger, this results in a short burst of air into the line insufficient to displace the clogging debris in the drain pipe. Due to the failure of these devices to properly seal the drain and their ability to only provide a short burst of air, these devices do not enable the user to regulate the pressure in the drain pipe. Accordingly, these devices cannot supply a continuous pressure for a desired amount of time.
- Another mechanical device utilizes a flexible tube or shaft (sometimes referred to as a “snake”) to attempt displacement of the clogging debris.
- This requires the user to direct the snake down the drain pipe to the clogged area and push or otherwise displace the debris.
- these devices are limited by their length, therein making it difficult or impossible to reach debris at remote locations in the drain pipe.
- structure often found in a drain such as a screen or other insert, prevents easy entry of the snake into the drain pipe. Therefore, the user may have to disassemble a portion of the drain or drain pipe to enable insertion of the snake. Additionally, the snake is messy to use. Debris located in the drain pipe covers the snake as it proceeds through the drain pipe. Upon removal of the snake, this debris must be cleaned or it may transfer to undesired locations.
- the plumbing arts have need for an apparatus that may seal the drain and drain pipe without any disassembly of the sink or drain pipe.
- the apparatus would enable a user to introduce a fluid into the drain pipe and regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris.
- the plumbing apparatus includes a substantially rigid member and a compressible member, one of the substantially rigid member and the compressible member including a valve.
- the compressible member may seal a drain and the drain pipe and a fluid may be introduced into the drain pipe through the valve to displace the debris clogging the drain line.
- the present invention presents a plumbing apparatus that enables a user to seal a drain and a drain pipe and then regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris.
- a user simply places the plumbing apparatus into the drain and manipulates an adjustable member, such as a wing nut and bolt, to draw a first and second plates toward one another. This movement of the plates results in compression of a compressible member.
- the plumbing apparatus seals the drain and drain pipe.
- the user may regulate the pressure in the drain pipe, therein promoting release of the debris causing the clog.
- the user may connect the auxiliary fluid source to a valve adapted to receive a fluid.
- the user may initiate the fluid delivery to the drain pipe. Since the plumbing apparatus seals the drain and drain pipe while enabling the user to deliver fluid to the drain pipe, the user may build up or otherwise regulate pressure in the drain pipe and ultimately displace the debris clogging the drain pipe. A skilled artisan will appreciate that this enables the user to deliver a substantially continuous fluid supply for an extended amount of time. Upon displacing the debris causing the clog, the user may disconnect the fluid supply and manipulate the adjustable member to allow movement of the first and second plates away from one another. This movement of the plates enables the compressible member to return to its relaxed position and allows for removal of the plumbing apparatus from the drain.
- the plumbing apparatus includes first and second substantially rigid members, such as plates, having recessed regions that project into an opening of the compressible member.
- the plumbing apparatus may also include an adjustable member that retains the first and second substantially rigid plates on the compressible member.
- the adjustable member may comprise a bolt and a corresponding wing nut positioned substantially in the center of the first and second plates. Movement of the wing nut in a clockwise direction draws the first and second plates towards one another, therein compressing the compressible member.
- the compression results in a wall of the compressible member engaging a surface of the drain, therein sealing the drain and drain pipe.

Description
- The present invention relates generally to a plumbing apparatus and more specifically, to an apparatus intended for use in unclogging a drain pipe. The apparatus enables the user to regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris.
- Since the advent of indoor plumbing, drain pipes have experienced clogging. From kitchen and bathroom sinks to tubs and showers, debris proceeding down the drain builds-up or otherwise becomes trapped in certain locations of the drain pipe. The limited diameter of many of these pipes and the complex array of bends and turns associated with the pipes in an indoor plumbing system contribute to the clogging. Once clogged, the sink or other device associated with the clogged drain pipe becomes substantially unusable, thereby requiring user intervention to dislodge or otherwise remove the debris.
- Several methods, compounds, and devices have been developed to unclog a drain pipe. For instance, one primitive method involves disassembling the drain pipe to physically remove the debris. This disassembly requires an extensive amount of time and often results in the standing water above the clog leaking out onto the floor or surrounding area. Moreover, many clogs reside in remote locations in the drain pipe that are nearly inaccessible without sever destruction to the plumbing system.
- In an attempt to overcome the need for disassembly, chemical compounds have been developed to chemically erode the debris. Unfortunately, these compounds are often highly toxic. This results in a health hazard to humans, as well as a danger to the environment. Furthermore, the introduction of chemicals into the water system results in increased costs for processing waste water. Additionally, the caustic chemicals in these compounds may damage the pipes in a plumbing system. These compounds also may not sufficiently erode large amounts of debris, thereby requiring additional devices or methods to unclog the drain.
- To overcome the disadvantages of chemical compounds, several mechanical devices have been developed. For example, plungers are well known devices for use in attempting to unclog a drain pipe. These devices generally include some form of cup or bellows for supplying bursts of air to the drain pipe. Unfortunately, these devices may only supply a small volume of air to the drain pipe for a very short amount of time. Moreover, these devices fail to adequately seal the drain associated with the clogged drain pipe. This results in air escaping around the cup or bellows during the plunging operation. Therefore, the user must repeat the plunging operation many times and may be unable to build up enough pressure in the drain pipe to displace the clogging debris.
- Other devices incorporate an air pump to direct a burst of air at an elevated pressure into the drain pipe. These devices includes a rubber cup that fits over the drain having the clogged drain pipe. Similar to the plunger, this rubber cup fails to properly seal the drain, therein allowing air to escape around the cup and failing to deliver a sufficient volume of air to displace the clog. Moreover, these devices utilize a chamber to build up pressure and a valve actuated by a trigger to release the air. Similar to the plunger, this results in a short burst of air into the line insufficient to displace the clogging debris in the drain pipe. Due to the failure of these devices to properly seal the drain and their ability to only provide a short burst of air, these devices do not enable the user to regulate the pressure in the drain pipe. Accordingly, these devices cannot supply a continuous pressure for a desired amount of time.
- Besides devices using bursts of air as the fluid to attempt unclogging the drain pipe, other devices use water to try displacing the debris. These devices sometimes include a bulb that fills with water, thereby expanding to seal the drain pipe. Once sealed the water proceeds down the drain pipe to unclog the debris. Unfortunately, these devices do not seal at the drain of the sink. Therefore, the user must disassemble a portion of the drain pipe to insert the device. This disassembly is time consuming and often results in standing water in the sink draining into the area surrounding the sink.
- Another mechanical device utilizes a flexible tube or shaft (sometimes referred to as a “snake”) to attempt displacement of the clogging debris. This requires the user to direct the snake down the drain pipe to the clogged area and push or otherwise displace the debris. Unfortunately, these devices are limited by their length, therein making it difficult or impossible to reach debris at remote locations in the drain pipe. Moreover, structure often found in a drain, such as a screen or other insert, prevents easy entry of the snake into the drain pipe. Therefore, the user may have to disassemble a portion of the drain or drain pipe to enable insertion of the snake. Additionally, the snake is messy to use. Debris located in the drain pipe covers the snake as it proceeds through the drain pipe. Upon removal of the snake, this debris must be cleaned or it may transfer to undesired locations.
- Accordingly, the plumbing arts have need for an apparatus that may seal the drain and drain pipe without any disassembly of the sink or drain pipe. The apparatus would enable a user to introduce a fluid into the drain pipe and regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris.
- In accordance with the purposes of the present invention as described herein, a new and improved plumbing apparatus intended for unclogging a drain pipe is described. The plumbing apparatus includes a substantially rigid member and a compressible member, one of the substantially rigid member and the compressible member including a valve. The compressible member may seal a drain and the drain pipe and a fluid may be introduced into the drain pipe through the valve to displace the debris clogging the drain line.
- Broadly stated, the present invention presents a plumbing apparatus that enables a user to seal a drain and a drain pipe and then regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris. A user simply places the plumbing apparatus into the drain and manipulates an adjustable member, such as a wing nut and bolt, to draw a first and second plates toward one another. This movement of the plates results in compression of a compressible member. As an exterior surface of a wall engages a sidewall of the drain, the plumbing apparatus seals the drain and drain pipe. At this point, the user may regulate the pressure in the drain pipe, therein promoting release of the debris causing the clog. To accomplish this, the user may connect the auxiliary fluid source to a valve adapted to receive a fluid. Next, the user may initiate the fluid delivery to the drain pipe. Since the plumbing apparatus seals the drain and drain pipe while enabling the user to deliver fluid to the drain pipe, the user may build up or otherwise regulate pressure in the drain pipe and ultimately displace the debris clogging the drain pipe. A skilled artisan will appreciate that this enables the user to deliver a substantially continuous fluid supply for an extended amount of time. Upon displacing the debris causing the clog, the user may disconnect the fluid supply and manipulate the adjustable member to allow movement of the first and second plates away from one another. This movement of the plates enables the compressible member to return to its relaxed position and allows for removal of the plumbing apparatus from the drain.
- In one embodiment, the plumbing apparatus includes first and second substantially rigid members, such as plates, having recessed regions that project into an opening of the compressible member. The plumbing apparatus may also include an adjustable member that retains the first and second substantially rigid plates on the compressible member. The adjustable member may comprise a bolt and a corresponding wing nut positioned substantially in the center of the first and second plates. Movement of the wing nut in a clockwise direction draws the first and second plates towards one another, therein compressing the compressible member. When the device becomes positioned in the drain, the compression results in a wall of the compressible member engaging a surface of the drain, therein sealing the drain and drain pipe. Introduction of a fluid, such as air or water, into the valve and drain pipe enables the user to regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris.
- In the following description there is shown and described one possible embodiment of this invention, simply by way of illustration of one of the modes best suited to carry out the invention. As it will be realized, the invention is capable of other different embodiments, and its several details are capable of modification in various, obvious aspects all without departing from the invention. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.
- The accompanying drawings incorporated in and forming a part of the specification, illustrate several aspects of the present invention, and together with the description serve to explain the principles of the invention. In the drawings:

FIG. 1 showing asink 10 with adrain 12 having adrain pipe 14 to be unclogged utilizing one embodiment of theplumbing apparatus 16 of the present invention. In one embodiment, theapparatus 16 seals thedrain 12 and thedrain pipe 14, therein enabling regulation of pressure in the drain pipe for a desired amount of time to displace the clogging debris. - In summary, the
plumbing apparatus 16 enables a user to seal thedrain 12 and thedrain pipe 14 and then regulate the pressure in the drain pipe for a desired amount of time to displace the clogging debris. A user simply places theplumbing apparatus 16 into thedrain 12 and manipulates anadjustable member 32, such as awing nut 36 andbolt 34, to draw first andsecond plates compressible member 22. As an exterior surface 30 a of awall 30 engages asidewall 42 of thedrain 12, theplumbing apparatus 16 seals thedrain 12 anddrain pipe 14. At this point, the user may regulate the pressure in thedrain pipe 14, therein promoting release of the debris causing the clog. To accomplish this, the user may connect the auxiliary fluid source (not shown) to avalve 44 adapted to receive a fluid. Next, the user may initiate the fluid delivery to thedrain pipe 14. Since theplumbing apparatus 16 seals thedrain 12 anddrain pipe 14 while enabling the user to deliver fluid to thedrain pipe 14, the user may build up or otherwise regulate pressure in the drain pipe and ultimately displace the debris clogging thedrain pipe 14. A skilled artisan will appreciate that this enables the user to deliver a substantially continuous fluid supply for an extended amount of time. Upon displacing the debris causing the clog, the user may disconnect the fluid supply and manipulate theadjustable member 32 to allow movement of the first andsecond plates compressible member 22 to return to its relaxed position and allows for removal of theplumbing apparatus 16 from thedrain 12. - The embodiment of the
plumbing apparatus 16 shown inFIG. 2 includes first and second rigid members, such as thefirst plate 18 and thesecond plate 20, and thecompressible member 22. Thefirst plate 18 rests on a top surface 22 a of thecompressible member 22, while thesecond plate 20 resides at an opposite end of thecompressible member 22, adjacent a bottom surface 22 b. Manipulation of the relative positions of the first andsecond plates compressible member 22, as discussed below. - As shown in
FIG. 2 , thecompressible member 22 may comprise a ring having thewall 30 defining anopening 28. Thecompressible member 22 is preferably formed from an elastomer material, such as rubber, but may be any compressible material. To assist with compression of thecompressible member 22, thefirst plate 18 may have an overall shape similar to the shape of the top surface 22 a of the compressible member. In the configuration shown, this results in the top plate having a substantially circular appearance. Similarly thesecond plate 20 also has a substantially circular appearance mimicking the shape of the bottom surface 22 b of thecompressible member 22. The circularity of the first andsecond plates plumbing apparatus 16 into thedrain 12 and also assists in sealing thedrain 12, as discussed below. Although shown as being substantially circular, the first andsecond plates compressible member 22 may comprise any shape or size, but would preferably be a shape adapted to fit within a drain. Additionally, the first andsecond plates - In one embodiment, the first and
second plates regions FIGS. 2, 3 a, and 3 b). The recessedregions lips regions opening 28 of thecompressible member 22. This configuration of recessedregions lips compressive member 22, thereby resulting in outward projection of thewall 30 of thecompressible member 22, as discussed below. - The
plumbing apparatus 16 also includes the adjustable member 32 (FIGS. 3 a and 3 b) that retains the first andsecond plates compressible member 22. In one embodiment, theadjustable member 32 may comprise multiple pieces, such as a threaded shaft or thebolt 34 andcorresponding wing nut 36, as shown inFIG. 2 . Thebolt 34 becomes inserted through anaperture 37 a in thesecond plate 20, theopening 28 of thecompressible member 22, and an aperture 38 a of thefirst plate 18. Thebolt 34 may include acollar 34 a adapted to engage theaperture 37 a and prevent rotation of thebolt 34. Once fully inserted, thewing nut 36 attaches to thebolt 34 to secure it to theplumbing apparatus 16. One ormore washers 35 may become positioned between thebolt 34 orwing nut 36 and the first andsecond plates adjustable member 32 substantially in the center of the first andsecond plates FIG. 1 b), during compression thecompressible member 22. - FIGS. 1 shows the
complete plumbing apparatus 16 with thecompressible member 22 in its uncompressed or relaxed condition prior to insertion of theplumbing apparatus 16 in thedrain 12. With thecompressible member 22 in the relaxed condition, theplumbing apparatus 16 may easily become placed in thedrain 12. In one embodiment shown inFIG. 3 a, the relaxedcompressible member 22 preferably has a smaller outer diameter D1 than the diameter D2 of thedrain 12. Thesecond plate 20 also has a diameter smaller than the diameter D2 of thedrain 12 to facilitate insertion of the plumbing apparatus into thedrain 12. Also, as shown, thefirst plate 18 preferably has an outer diameter D3 larger than the diameter D2 of thedrain 12. In this configuration, a portion of thelip 24 resides outside of thedrain 12 and engages an inner surface 10 a of the sink. - To seal the
drain 12 anddrain pipe 14 after installation of theplumbing apparatus 16, a user turns thewing nut 36 in a clockwise direction Z1 (FIG. 1 b) to draw the first andsecond plates plates compressible member 22. Accordingly, the greater thewing nut 36 becomes tightened, the more thecompressible member 22 becomes compressed, therein resulting in radial expansion of thewall 30. In other words, the movement of the first andsecond plates wall 30 of the compressible member to outwardly buckle or bulge. As thewall 30 projects in the radial direction, the exterior surface 30 a of thewall 30 engages thesidewall 42 of the drain. This engagement of thewall 30 of thecompressible member 22 with thesidewall 42 seals thedrain 12 anddrain pipe 14. - To unseal the
drain 12 anddrain pipe 14, the user simply turns thewing nut 36 in the counterclockwise direction Z2 (FIG. 1 b). The elastomer material forming thecompressible member 22, desires to return to its relaxed and uncompressed state. Accordingly, as thewing nut 36 becomes loosened, thecompressible member 22 pushes the first andsecond plates compressible member 22 returns to its fully relaxed condition. - As mentioned above, another feature of the
present plumbing apparatus 16 is that it enables regulation of the pressure in the drain pipe therein promoting release of the debris causing the clog. To facilitate this, theapparatus 16 includes thevalve 44 adapted to receive a fluid, such as air or water, from an auxiliary source (not shown). In one embodiment, thevalve 44 comprises a standard self-sealing air valve similar to those found on car tires. Thevalve 44 includes astem 46 having a base 48 with anaperture 48 a positioned at one end andplunger 50 at the other end. As shown inFIGS. 2, 3 a, and 3 b, thevalve 44 may reside on thesecond plate 20 with the base 48 attached at the aperture 37 b, therein placing theaperture 48 a in fluid communication with thedrain pipe 14. In this configuration, thestem 46 projects through theopening 28 of thecompressible member 22 and an aperture 38 b of thefirst plate 18. This enables a user to place the auxiliary fluid supply source in fluid communication with thevalve 44. For instance, a user may connect a manual air pump or an air compressor to thevalve 44. The air pump or compressor includes a connector that depresses theplunger 50 of thevalve 44 such that air may proceed through thestem 46 and out theaperture 48 a. Additionally, theplunger 50 andvalve 44 enable a user to bleed or release pressure in the drain pipe. For instance, thevalve 44 withplunger 50 allow the user to build up pressure in thedrain pipe 14 and then release some of the pressure, such as when cycling pressure in thedrain pipe 14 or removing theplumbing apparatus 16 after displacing clogging debris. - The present invention presents a
plumbing apparatus 16 that enables placement of theapparatus 16 in thedrain 12, without disassembly of thedrain 12 ordrain pipe 14, for sealing thedrain 12 and thedrain pipe 14. This enables the user to introduce a fluid into the drain pipe and regulate the pressure in the drain pipe for a desired amount of time. Thus, theapparatus 16 allows a user to displace clogging debris at any location in thedrain pipe 14. - The foregoing discussion was chosen to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications suited to the particular use contemplated. For example, the
plumbing apparatus 16 may include any number of rigid members,plates compressible members 22. Additionally, theplumbing apparatus 16 may have any size or shape to accommodate various configurations ofdrains 12. Instead of becoming placed in thedrain 12 for sealing thedrain 12 and thedrain pipe 14, theplumbing apparatus 16 may become placed directly in thedrain pipe 14. Additionally,multiple plumbing apparatuses 16 may be used simultaneously in a plumbing system or otherwise in conjunction with one another. Furthermore, theplumbing apparatus 16 may become configured without avalve 44, therein only serving to seal thedrain 12 or thedrain pipe 14. All modifications and variations are within the scope of the invention as determined by the claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
