The drain adapter is self-biased to the closed position. Attachment of the actuator to the drain adapter causes the drain adapter to be in the open position and removal of the actuator from the drain adapter causes the drain adapter to return to the closed position. The second fluid container is removably attachable to the drain adapter and contains fluid drained from the first fluid container when the drain adapter is in the open position.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/842,461, the entire contents of which are hereby incorporated by reference.
- The present invention relates generally to systems and methods for draining and containing a fluid.
- Engines and many other types of machines include various fluids (e.g., water, coolants, lubricants, gear oil, motor oil, transmission fluid, hydraulic fluids, brake fluids, etc.) that require periodic draining and replacement. Draining the fluids typically includes removing a drain plug in the system containing the fluid and allowing the fluid to drain into a first container, typically a large pan, that is placed below the open drain hole.
- During the draining process the fluid often is spilled, dripped and splashed on the floor or ground below, on the equipment and on the person draining the fluid. Such spills require cleaning and disposal of the residue. Further, the fluid must be properly disposed of/recycled to increase safety, reduce pollution and conserve resources. Properly disposing of the fluid typically requires the drained fluid to be poured from the first container into a second container for transport to the appropriate disposal/recycling location.
- In view of the foregoing, there is a need for a system for more easily and neatly draining the fluids that can also contain the fluids and reduce or substantially eliminate splashing, spilling, dripping of the fluid.
- The present invention provides a system for and a method of draining fluid. In an embodiment, the system comprises a drain adapter configured for attachment to a first fluid container, an actuator that is removably attachable to the drain adapter and a second fluid container. The drain adapter has a closed position, in which fluid is prevented from draining from the first fluid container, and an open position, in which the fluid is allowed to drain from the first fluid container. The drain adapter is self-biased to the closed position. Attachment of the actuator to the drain adapter causes the drain adapter to be in the open position and removal of the actuator from the drain adapter causes the drain adapter to return to the closed position. The second fluid container is removably attachable to the drain adapter and contains fluid drained from the first fluid container when the drain adapter is in the open position.

-
FIG. 13 shows a cut-away view of a fluid container valve assembly in accordance with an embodiment of the present invention. -
FIG. 1 is a pictorial view of a fluid drainingsystem 100 in accordance with an embodiment of the present invention. Thesystem 100 includes adrain adapter 102, ahandle 104 and afluid container 106. -
FIG. 2 shows a side view of thesystem 100 in accordance with an embodiment of the present invention. Theadapter 102 includes a fluid valve assembly including avalve 108 and avalve collar 110 having avalve seat 112 at its top portion. Thevalve collar 110 may be threaded so that it can be attached to machinery by being threaded into a threaded receptacle for an original drain plug (not shown). Thevalve 108 is shown inFIG. 2 in an open position. In a closed position, thevalve 108 contacts thevalve seat 112. -
FIG. 3 shows thesystem 100 separated into the three parts: thedrain adapter 102; thehandle 104; and thefluid container 106, in accordance with an embodiment of the present invention. InFIG. 3 , theadapter 102 is shown connected to afluid container 114 of piece ofmachinery 116 in place of the drain plug (not shown) that was previously part of themachinery 116. -
FIG. 4 shows a cut-away view of thesystem 100 separated into the three parts: thedrain adapter 102; thehandle 104; and thefluid container 106, in accordance with an embodiment of the present invention.FIG. 4 also shows various cutaway details of theadapter 102, thehandle 104 and thefluid container 106. Referring to theadapter 102, thevalve 108 is shown in the closed position with the valve substantially sealed to thevalve seat 112 of thevalve collar 110. The valve assembly can also include acoil spring 118 that biases the valve into the closed position. Theadapter 102 also includes anopening 120 into which avalve actuator 122 can enter. Theactuator 122 is coupled to thehandle 104 and may include a wedge portion which slides against thevalve 108 to push thevalve 108 open when theactuator 122 is inserted into theopening 120. - It will be apparent that the wedge portion of the
actuator 122 generates a mechanical advantage by converting the force applied by a person sliding theactuator 122 into thedrain adapter 102 into a valve-opening force. It will be apparent that another means of generating a mechanical advantage may be used in conjunction with sliding theactuator 122 into thedrain adapter 102. For example, a lever or gearset may be utilized to actuate thevalve 108. -
FIG. 5 shows the fluid draining system with the handle attached to the fluid container in accordance with an embodiment of the present invention. Referring now toFIGS. 4 and 5 , as the wedge portion of theactuator 122 enters theopening 120, the wedge catches alower end 124 of thevalve 108 and forces the valve upward against the tension of thespring 118. Thus, theactuator 112 pushes thevalve 108 in a direction into thefluid container 114 to open thevalve 108. Avalve stem 126 extends from thevalve 108, though thevalve collar 110 and is connected to thelower end 124 of the valve. -
FIG. 6 shows a pictorial view of the fluid drainingsystem 100 with thehandle 104 being attached to thefluid container 106 in accordance with an embodiment of the present invention. Referring now toFIGS. 4 and 6 , a fluid container assembly includes thefluid container 106 and afluid container collar 128 coupled to thefluid container 106. Thefluid container 106 is secured to thehandle 104 by a locking mechanism. Thefluid container collar 128 includes afirst portion 130 of the locking mechanism. Correspondingly, asecond portion 132 of the locking system that can intermesh with thefirst portion 130 of the locking mechanism is coupled to thehandle 104. As shown inFIG. 6 , thefirst portion 130 and thesecond portion 132 of the locking mechanism are secured to each other by inserting thesecond portion 130 into the first portion and rotating them 90 degrees with respect to each other. It should be understood that any type of locking mechanism could be used (e.g., threaded, friction, o-ringed, with a locking pin, or any other suitable system). - As shown in
FIG. 6 , aresidue remover 134 can also be coupled to thehandle 104. Theresidue remover 134 removes fluid residue from the valve assembly of thedrain adapter 102 as the handle is removed from thedrain adapter 102. By way of example, theresidue remover 134 can be an absorbent pad or a squeegee having a flexible edge that wipes the reside or other system to substantially remove fluid residue from theadapter 102 so as to inhibit dripping of the fluid after theactuator 122 is removed from theadapter 102. - When the
actuator 122 is inserted into theadapter 102 and the valve assembly of theadapter 102 is in the open position, fluid drains from themachinery 116 and into thefluid container 106 via anopening 136 in thecollar 128. Thehandle 104 may also include anopening 138 through which the fluid passes. Thecollar 128 can also include avalve 140 that automatically closes theopening 136 in thecollar 128 when thehandle 104 is not connected to thefluid container 106. Thevalve 140 can thereby minimize fluid spillage from thefluid container 106 after the fluid has been drained into thefluid container 106. Alternatively or additionally, a removable cap (not shown) can be used to close theopening 136. - Referring again to
FIG. 4 , thedrain adapter 102 can include anouter sleeve 142 and aninner housing 144. Thesleeve 142 is slidable with respect to theinner housing 144. Thevalve collar 110 is attached to theinner housing 114 so that thevalve 108 and valve assembly are also attached to theinner housing 144. Thecoil spring 124 may be contained within theinner housing 144. Theopening 120 may be formed in theinner housing 144. Theinner housing 144 may include anopening 146 through which the fluid drains when thevalve 108 is opened. When the fluid is not being drained, the outer sleeve covers theopening 146 and protects the valve assembly from damage which might be caused by debris entering theopening 146. In this closed position, thedrain adapter 102 is substantially the shape of a rectangular box. Both theouter sleeve 142 and theinner housing 144 can have a rectangular cross section. In addition, theopening 120 and theactuator 120 can have a rectangular cross section. - In a preferred embodiment, when the
actuator 122 is inserted into theopening 120 of theinner housing 144, the assembledhandle 104 andfluid container 106 push against theouter sleeve 142 which causes theouter sleeve 142 to slide back, exposing theopening 146. When theactuator 122 is removed, theouter sleeve 142 may automatically slide back into the closed position. For example, a spring may be attached to theouter sleeve 142 and theinner housing 144 to bias theouter sleeve 142 to this closed position. Alternatively, theouter sleeve 142 may be slid back and forth manually. For example, when the fluid is to be drained, the person draining the fluid may first slide theouter sleeve 142 back and, then, once the fluid has been drained, the person may slide theouter sleeve 142 to the closed position. -
FIG. 7 is a flowchart diagram that illustrates method operations performed in using thesystem 100 for draining fluid in accordance with an embodiment of the present invention. In anoperation 705, thedrain adapter 102 is installed to a piece ofmachinery 116. More particularly, a threaded drain plug of afluid container 114 of themachinery 116 may be removed and theadapter 102 may be attached to themachinery 114 by the threaded portion of thecollar 110 being installed in place of the drain plug. - To drain the fluid in the
machinery 116, thefluid container 106 may be secured to thehandle 104 in anoperation 710. Thefluid container 106, thehandle 104 and theactuator 122 are thus assembled as a single unit. In anoperation 715, theactuator 122 is inserted into theadapter 102. This may be accomplished by a person taking a hold of thehandle 104, inserting theactuator 122 into theopening 120 of thedrain adapter 102 and moving (i.e. sliding) theactuator 122 into position. - As the
actuator 122 is inserted fully into theadapter 102, thevalve 108 is opened and the fluid is allowed to drain from themachinery 116 into thefluid container 106 in anoperation 720. The assembledhandle 104 andfluid container 106 are thus attached to thedrain adapter 102 while the fluid is drained. The fluid can drain through theopening 140 in thehandle 104 and theopening 136 in thecollar 130. - When the fluid is drained into the
fluid container 106, theactuator 122 is removed from theadapter 102 in anoperation 725. This may be accomplished by pulling thehandle 104. Thevalve 108 then closes under tension of thespring 118. - In an
operation 730, thefluid container 106 can be removed from thehandle 104. - The
drain adapter 102 can remain attached to themachinery 116 upon completion of the method. Therefore, once thedrain adapter 102 has been installed, the fluid can be drained easily and conveniently without the use of mechanic's tools, such as a wrench, and without having to manipulate a threaded fastener. - The
fluid container 106 can be sufficiently large to accommodate at least the volume of fluid to be drained. Alternatively, if the volume of fluid to be drained is larger than the largest sizefluid container 106 available, then theactuator 122 can be removed from theadapter 102 when thefluid container 106 is nearly filled to capacity. Another fluid container can be attached to thehandle 104 and the process repeated until the desired volume of fluid is drained from themachinery 114. - The fluid-filled
fluid container 106 can be used as the container to deliver the fluid for disposal/recycling. Thefluid container 106 can be made from any suitable material that is compatible with the fluid to be drained. Thefluid container 106 can be a bag formed from a flexible material such as polyethylene so that the fluid container can fit into tight spaces. For example, there may be insufficient vertical clearance for thefluid container 106 to hang down from thehandle 104. - The
adapter 102, thehandle 104 and the various components thereof can be formed from any suitable materials compatible with the environment, the desired wear and tear characteristics and compatible with the fluids. For example, thehandle 104 and thefluid container collar 128 are preferably formed of plastic. However, because thedrain adapter 102 may be left attached to themachinery 116 during normal operation of themachinery 116, thedrain adapter 102 is preferably formed primarily of metal, such as steel. - In an embodiment, the
machinery 116 is an automobile and the fluid is oil used to lubricate an internal combustion engine of the automobile. In this case, thedrain adapter 102 is attached to an oil pan of the automobile. For such an application, the profile of thedrain adapter 102 is preferably minimized so as to provide clearance between thedrain adapter 102 and other elements of the automobile and between thedrain adapter 102 and the roadway. In a preferred embodiment, the height of theouter sleeve 142 of thedrain adapter 102 is approximately 16 mm or less. - As described above, the valve assembly of the
drain adapter 102 comprises thecoil spring 118 that biases thevalve 108 into contact with thevalve seat 124 to close the valve. Thevalve 108 is opened by theactuator 122 separating thevalve 108 from thevalve seat 124 by pushing thevalve 108 into thefluid container 114 of themachinery 116. - In an alternative embodiment, the valve assembly comprises a non-coiled spring retainer that biases a valve into contact with a valve seat to close the valve. In this embodiment, the valve is opened by the actuator separating the valve from the valve seat by pushing the valve in a direction away from the fluid container of the machinery.

Elements of thesystem 100′ that correspond to those of thesystem 100 are given like reference numerals. Thesystem 100′ includes the same elements and functions in the same way as thesystem 100 with the exception of differences discussed below. As before, thesystem 100′ includes adrain adapter 102, ahandle 104, and afluid container 106. And, avalve actuator 122 coupled to thehandle 104 opens a valve assembly of thedrain adapter 102 when theactuator 122 is inserted into anopening 120 in thedrain adapter 102. However, rather than acoil spring 118 as in the embodiments ofFIGS. 1-6 , anon-coiled spring retainer 148 is provided in this embodiment. -
FIG. 9 shows a top view of thespring retainer 148 and avalve 150. As shown inFIG. 9 , thevalve 150 is attached to avalve frame member 152. Thevalve frame member 152 is supported at each end by thespring retainer 148, with a firstspring retainer portion 148A supporting one end of theframe member 152 and a secondspring retainer portion 148B supporting the other end of theframe member 152. The first and secondspring retainer portions -
FIG. 10 shows a bottom view of thespring retainer 148 and thevalve 150 in accordance with an embodiment of the present invention. As shown inFIG. 10 , thespring retainer portions openings 154. In this case, theframe member 152 includesposts 156 that fit into theopenings 154 to prevent theframe member 152 from slipping off of thespring retainer 148. -
FIG. 11 shows a cut-away view of thefluid draining system 100′ in accordance with an embodiment of the present invention. As shown inFIG. 11 , a threaded portion of avalve collar 158 is attached to afluid container 114 ofmachinery 116. In addition, theactuator 122 is inserted into thedrain adapter 102 and theouter sleeve 142 is slid back from the valve assembly which is attached to theinner housing 144. As is also shown inFIG. 11 , thevalve 150 is pushed down against the tension of thespring retainer 148 and in a direction away from thefluid container 114. Thevalve 150 is, therefore, opened which allows fluid from drain from thecontainer 114 of themachinery 114 to thefluid container 106. - The
actuator 122 includes wedge portions, each of which slides against the ends of thevalve frame 152 to apply tension to each of thespring retainer portions spring retainer portions valve 150 open. - FIGS. 12A-B show cut-away views of a valve assembly including the
valve 150 and thevalve collar 158 of thefluid draining system 100′ in closed and open positions, respectively, accordance with an embodiment of the present invention. More particularly,FIG. 12A shows thevalve 150 in a closed position in which thevalve 150 is substantially sealed against avalve seat 160 of thecollar 158. Thevalve 150 is biased in the closed position by thespring retainer 148. Thecollar 158 may include acylindrical guide channel 162 into which acylindrical guide 164 extends. Theguide 164 is coupled to thevalve 150 and tends to keep thevalve 150 aligned with thevalve seat 160 while thevalve 150 is being opened and closed. Thevalve seat 160 may include a rubber or rubber-like gasket or over-mold to improve the quality of the seal between thevalve 150 and thevalve seat 160 when thevalve 150 is closed. In an embodiment, the gasket is formed of a thermoplastic elastomer that is both heat and oil resistant. -
FIG. 12B shows thevalve 150 in an open position in which thevalve 150 is pushed away from thevalve seat 160. In this position, fluid is allowed to drain from themachinery 116, as shown by the arrows. Also, in the open position, theguide 164 is partially extracted from theguide channel 162. Referring again toFIG. 9 , the fluid may travel throughpassages 166 provided in thevalve frame member 152. -
FIG. 13 shows a cut-away view of a valve assembly for thefluid container 106 in accordance with an embodiment of the present invention. As shown inFIG. 13 , the valve assembly includes anupper valve portion 168 and alower valve portion 170, each having openings (e.g. four). Thehandle 104 may be attached to thefluid container 106 by thelocking mechanism FIGS. 4 and 6 . In addition, rotation of thehandle 104 during attachment to thefluid container 106 causes the openings in theupper valve portion 168 and thelower valve portion 170 to become aligned which opens the valve assembly by formingfluid passages 170. Conversely, rotation of thehandle 104 in the opposite direction during removal of thefluid container 106 from thehandle 104 causes the openings to be out of alignment, thereby closing thepassages 170 and closing the valve assembly. - When the
valve 150 of thedrain adapter 102 is opened, its lower surface may contact anupper surface 174 of thecollar 128. In an embodiment, theupper surface 174 comprises a rubber or rubber-like gasket or over-mold to improve the quality of the seal between thevalve 150 and thecollar 128 when thevalve 150 is opened. In an embodiment, the gasket is formed of a thermoplastic elastomer that is both heat and oil resistant. - Although the foregoing invention has been described in some detail for purposes of clarity of understanding, it will be apparent that certain changes and modifications may be practiced within the scope of the described embodiments. Accordingly, the present embodiments are to be considered as illustrative and not restrictive, and the invention is not to be limited to the details given herein, but may be modified within the scope and equivalents of the described embodiments.
