Description

TECHNICAL FIELD

The present disclosure relates to a toilet flushing system constructed to economically dispense fluids and/or waste for a given situation.

BACKGROUND

With conventional flushing toilets, a significant amount of water is used with each flush that after certain uses is not wholly required and is thus wasteful of water. Dual flushing arrangements provide for low volume and high volume flushes, but these are generally of relatively complex configurations. Furthermore, such arrangements usually cannot be retrofitted, and therefore if dual flushing is required, new flushing systems are needed for each toilet at a location.

SUMMARY

One embodiment of the present disclosure features a toilet flushing system for providing both high and low volume flush control. The toilet flushing system comprises a lever rotatable to a first position for a low volume flush and rotatable to a second position for a high volume flush. The system further comprises a central assembly having a housing locatable in a toilet cistern selectively enclosing a flush valve for sealing an exit aperture. The flush valve is selectively opened for dispensing water during both the high and low volume flushes through the exit aperture. The system also comprises a control assembly having an actuator, first link, second link, and swivel member that provide high volume flush control by selectively opening a closure member rotatably attached to the housing. The rotation of the lever to the second position mobilizes the actuator such that the first link, swivel member, second link, and closure member are rotated from a closed position to a high volume flush position.

Another embodiment of the present disclosure comprises a toilet flushing system for providing both high and low volume flush control. The toilet flushing system comprises a lever rotatable to a first position for a low volume flush and rotatable to a second position for a high volume flush. The system further comprises a central assembly having a housing locatable in a toilet cistern selectively enclosing a flush valve for sealing an exit aperture. The flush valve is selectively opened for dispensing water during both the high and low volume flushes through the exit aperture. The system also comprises a control assembly comprising an actuator, first link, second link, and swivel member that provide high volume flush control by selectively opening a closure member rotatably attached to the housing. The swivel member is totally supported by the first and second links via a first link opening in the swivel member for receiving an end portion of the first link and a second link opening in the swivel member for receiving an end portion of the second link. The first link opening is positioned in the swivel member opposite the second link opening. The rotation of the lever provides translational movement of the actuator resulting in rotational movement of the first link, swivel member, second link, and closure member. The amount of rotational movement in the first link is greater than the rotational movement of the second link to allow for opening of the closure member for a high volume flush.

A further embodiment of the present disclosure comprises a toilet flushing system for providing both high and low volume flush control. The toilet flushing system includes a lever rotatable to a first position for a low volume flush and rotatable to a second position for a high volume flush and a central assembly comprising a housing locatable in a toilet cistern selectively enclosing a flush valve for sealing an exit aperture in the cistern. The flush valve is selectively opened for dispensing water during both the high and low volume flushes through the exit aperture. The system further comprises a control assembly having an actuator, first link, second link, and swivel member that provide high volume flush control by selectively opening a closure member that is rotatably attached to the housing. The swivel member supported by the first and second links via a first link opening in the swivel member for receiving an end portion of the first link and a second link opening in the swivel member for receiving an end portion of the second link. The first and second link openings are axially offset about the swivel member. The rotation of the lever provides translational movement of the actuator resulting in rotational movement of the first link, swivel member, second link, and closure member. The amount of rotational movement in the first link is greater than the rotational movement of the second link to allow for opening of the closure member for a high volume flush.

DETAILED DESCRIPTION

The present disclosure relates to a toilet flushing system constructed to economically dispense fluids and/or waste for a given situation. In particular, the present disclosure provides a flexible assembly adaptable to various size tanks and flushing arrangements. The system of the present disclosure further provides enhanced kinematic mobility in the components comprising the system. While other high and low flush systems exist, (including applicant's U.S. Pat. No. 7,219,375 issued May 22, 2007 issued to Steadman which incorporated herein by reference in its entirety), the flushing system of the present disclosure is economically manufactured and assembled and provides improved mobility during the high volume flush operations and flexibility for adapting to the number of different tanks manufactured.

Conventional toilet systems include a handle mounted on the tank used to lift a flapper valve to release the water located into the tank during a flushing operation. By turning the handle, an arm attached to a handle shaft and to the flapper valve via a chain is raised enough to allow the tank to flush. The length of the arm produces an arc length much greater than the distance in which the handle and shaft are rotated in order to accomplish a low-volume flush. This same challenge exists where a system of linkages requires a long pull to enable a high volume flush in opening a door or gate through the same flapper valve while not inhibiting the flow of water exiting from the tank during the rotation.

The present disclosure enables a fast, full-tank, high volume flush that requires lever to be rotated slightly further than what is required for a low volume flush, which in turn takes the small amount of shaft rotation in a lever an converts it into a much greater rotation of a large door or gate an amount wide enough and rotates it fast enough not to restrict the flow of the remaining water in the tank. Stated another way, the control system and assembly of the present disclosure takes very little rotation in a toilet handle or lever and converts to a much larger angle and faster rotation of a door, controlling a high volume flush.

The present disclosure achieves this fast and wide rotation through a double crank shaped swiveling rod arrangement that includes a small crank end on a first link connected to the lever via a sliding strip and a larger bottom crank end connected via other means discussed in more detail below. This allows the door or gate to open enough and fast enough with the actuation of the lever to give a high-volume flush to substantially all the water remaining in the tank.

Referring now to the figures and in particular FIG. 1 is a toilet 10 that includes a tank or cistern 12 and flushing system 14. The flushing system 14 comprises a flush valve 16 operated by a lever 18 that causes pivotal movement of a bar 20, which connects the flush valve 16 to a chain or tether 22. In use, the cistern 12 in which the flushing system 10 is located automatically fills through a refill tube 24 to a required height. This required height can be adjusted through a knob 26. Filling takes place into an overflow pipe 28 that can receive water in the event that excess water is supplied into the cistern 12.

In order to achieve a low volume flush in the flushing system 10, the lever 18 is pushed downwardly causing pivotal movement about a fixture 30 (see FIGS. 2-4 and 9) through its pivot arm 32 that passes through an aperture 34 of the tank and fixture. By rotating the lever 18, the bar 20 is raised to a first position via a cam assembly 36 (see FIG. 10) that is connected to the pivot arm 32 located on the inside of the cistern 12, causing the flush valve 16 to operate to achieve a low volume flush without causing movement to linkages in a control assembly 100 associated with the high volume flush. In FIG. 10, the bar 20 is positioned through a rounded opening 21 in a pivot plate 23 that is welded (W) to the bar. The pivot plate 23 is rotatably secured to the fixture 30 by a fastener 25, such as a rivet or screw and provides for pivotal movement or rotation of the bar 20. The fixture 30 includes a recess 27 that allows for the rotation of the bar 20 and pivot plate 23 as the cam assembly 36 raises the bar to the first position for a low volume flush.

In use, if only a low volume flush is required, the lever 18 is pressed downwardly until any particular resistance is felt. This causes flushing in a conventional manner with the cam assembly 36 having a cam 38 engaging against the bar 20 lifting the tether 22 and hence flush valve 16, thereby causing water to be flushed into the toilet 10 as illustrated in FIG. 3 when transitioning from the closed position of FIG. 2 to the low volume flush position of FIG. 3. The water flushed is however only the volume within a housing 50 and the volume of water spaced above the top of the housing, i.e. the water between the lines 44 and 46 in FIG. 8.

The cam assembly 36 includes the cam 38 connected to the pivot arm 32 and further includes a first lobe 40 and a second lobe 42. The low volume flush (or first position) is achieved as the first lobe 40 of the cam 38 contacts the bar 20 between position “A” to position “B”, as illustrated in FIG. 10. While the bar 20 is raised in the first position, the tether 22 raises the flush valve 16, allowing a low volume flush of the volume of water located in and above the housing 50 illustrated in FIGS. 1 and 8. Following flushing, the flush valve 16 will automatically reclose and the cistern 12 will be refilled through the refill tube 24. There are of course other conventional types of flushing systems, incorporating for instance a floating ball valve or other type of floating valves which cause the cistern to stop filling when a required water level therein is detected.

Referring again to the figures and in particular FIGS. 1-4, the flushing system 10 further comprises the housing 50 surrounding the flush valve 16 that allows the water located therein and above the housing to exit during a low volume flush achieved by the pivoting of the lever 18 and raising the flush valve 16 via raising tether 22, as described above. The housing 50 includes an open top 52 and an exit opening 54 located in a base 56 through which flushing water can pass. In the isometric views of FIGS. 5 and 6, the housing 50 has a generally circular front section 58 extending from a smaller generally circular rear section 60. These shapes are chosen so as to not cover and thus permit free access to, the conventional mounting holes 62 (see FIG. 1) for the cistern 12, however, the cistern can be configured to any shape or geometry without departing from the spirit and scope of the claimed invention.

A large flush opening 70 is provided in the housing 50 between the front section 58 and rear section 60. The large flush opening 70 is sealed by a closure member 72, forming a gate that is pivotally mounted by a hinge 74 attached to the outside of the housing 50 and passing through a slot 76 located in the closure member. The closure member 72 is biased to a closed position by a biasing member 78 such as a spring that attaches to several adjustment apertures 80 located in the housing 50. The closure member 72 further comprises a web 82 integral to an outside surface 84 of the closure member that provides strength during an opening and closing operation.

A control assembly 100 is provided for selective opening of the closure member 72 as follows. The control assembly 100 when operated allows for a high volume flush control of the cistern 12 that includes not just the water in and above the housing 50, (low volume flush) but substantially all the water located in the cistern. The control assembly 100 connects to the lever 18 to the closure member 72. The control assembly 100 is attached to the cistern 12 and housing 50 through horizontal and vertical fixtures 102, 104, respectively. The fixtures 102, 104 are made from plastic or metal and include adjustment slots 106 that provide flexibility between varying size tanks 12 and locations of housings 50 and are attached through conventional fasteners 108 known by those skilled in the art, such as screws and rivets. The slots 106 allow for movement and adjustment of the control assembly 100 along “X” and “Y” directions.

Illustrated in FIG. 2 is an assembly view of the control assembly 100 assuming a closed position of the closure member 72. Connecting the closure member 72 to the lever 18 is a slide actuator 110 slidably connected to a first link 112 that is pivotally connected to a second link 114. The slide actuator 110 includes first and second slots 116, 118, respectively that allow for adjustment in various size cisterns 12. The first slot 116 is adjustably connected for pivotal rotation by a fastener 108 to the second lobe 42 of cam 38. The adjustment provided by the first slot 116 and second slot 118 further accommodate the engagement of the second slot with a first elbow portion 120 of the first link 112 at a first end 122 of the second slot during a high volume flush. The first end 122 of the second slot 118 does not travel far enough during a low volume flush to engage the first elbow, therefore the closure member 72 is remains closed during low volume flushing operations. The actuator 110 is constructed from steel flat stock, but could be equally made from aluminum or plastic without departing from the spirit and scope of the claimed invention. The actuator 110 includes an aperture 111 at an end opposite the first slot 116 that connects to a spring 113 that is attached to horizontal fixture 102. The spring 113 biases the actuator 110 to a low flush or closed position of the closure member 72.

As the lever 18 is rotated the cam 38 shifts from a closed position of FIG. 2 to (a low flush) position of FIG. 3 to (an open high volume flush) position of FIG. 4 as rotation of the cam 38 about pivot arm 32 occurs. The rotation of the cam 38 beyond the low volume position and on to a high volume position causes both rotation and translation in the slide actuator 110 relative to a first elbow portion 120, allowing the first end 122 of slot 118 to engage the elbow portion causing rotation of the first link 112 in the direction of arrow “A” FIG. 4. The rotation of the first link 112 results in the rotation of a second elbow portion 124 from the closed position of FIG. 2 and 3 to the open position of FIG. 4, further indicated by the direction of the arrows A and B in FIG. 4. The first link 112 is rotatably connected about a link support member 126 having a pivotal opening 128 through which the cylindrical construction of a mid section 130 the first link rotates during the movement of the lever 18 to the high flush condition of FIG. 4.

The first link 112 further comprises an action end 132 extending from the first elbow portion 120 and a reaction end 134 extending from the second elbow portion 124. The reaction end 134 extends through a swivel member 140. The swivel member 140 is cylindrically shaped having a hollow section 142. The reaction end 134 passes through a lower end 147 of the swivel member 140 through its hollow section 142 and out an upper end 149. Such connection allows for enhanced mobility and security between the swivel member 140 and the first link 112. In the illustrated embodiment, the swivel member 140 is made from a polymeric material, such as nylon. However, the swivel member 140 could be made from other materials such as metal, fibrous, or ceramic having a low coefficient of friction without departing from the spirit and scope of the claimed invention. The swivel member 140 pivotally connects the first link 112 to the second link 114, allowing independent pivotal movement therebetween.

The second link 114 comprises a coupler end 144, a midsection 146 having a first elbow 148 and second elbow 150, and a closure end 152. Both the first and second links, 112, 114, respectively are cylindrical stock made from approximately ⅛ to 3/16 diameter aluminum or steel. The coupler end 144 is pivotally connected into the swivel member 140. The coupler end 144 passes through the upper end 149 of the swivel member 140 through its hollow section 142 and out the lower end 147. Such connection provides enhanced security and mobility between the swivel member 140 and second link 114. Rotating the first link 112 from the closed position of FIGS. 2 and 3 to the open position of FIG. 4 results in the rotation of the swivel member 140 and second link 114 as indicated by the arrows in FIG. 4.

The reaction end 134 and coupler end 144 form a slip fit pivotal connection with the swivel member 140. The configuration of the second elbow portion 124 of the first link 112 supports the swivel member 140 from its lower end 147, while the first elbow portion 148 of the second link 114 counter balances the swivel member from its upper end 149. The construction and location of the swivel member 140 between first and second links 112, 114 provides for the ease in movement and quick reaction in the opening and closing of the closure member 72 through the rotation of the lever 18 for a high volume flush. The low coefficient of friction in the swivel member 140 allows the reaction end 134 and coupler end 144 to independently rotate with respect to the rotation of the swivel member 140 as well force the rotation of the swivel member during rotation of the first and second links, 112, 114, respectively.

The closure end 152 of the second link 114 is attached through an aperture 154 in the closure member 72. The closure member 72 is strengthened by the web 82 that extends the length of the closure and is adjacent the aperture 154. The second elbow portion 150 provides a hook around the closure member 72 and rotates the closure member from a closed position of FIG. 2 and 3 to the open position of FIG. 4 indicated by the arrows (A and B) upon operation of the control assembly 100 when the lever 18 is rotated for the high volume flush.

During operation when a higher volume of flush is desired, the lever 18 is rotated beyond the location for a low volume flush. This causes further rotation of the cam assembly 36, and more specifically the cam 38 from FIG. 2 and 3 (a closed position) to an open position in FIG. 4, further illustrated in the detail drawing of FIGS. 10 and 11, as the cam 38 rotates from points A to B. As a result of the cam's rotation, a connecting arm 39 passes through the first slot 116 and held to the slide actuator 110 through a fastener 108.

Movement of the slide actuator 110 forces the first link 112 to rotate to the open position of FIG. 4. The rotation of first link 112 results in the rotation of swivel member 140 from the closed position of FIGS. 2 and 3 to the open position of FIG. 4. During the rotation of the swivel member 140, the reaction end 134 and coupler end 144 rotate within swivel member, allowing for smooth and quick transitioning of the closure member 72 from the closed position of FIGS. 2 and 3 to the open position of FIG. 4 and vice versa. As a result, a high volume flush is achieved as substantially all the water above the line 156 (FIG. 8) which is level with the bottom of the tank 12, will flush, irrespective of whether this water is in the housing 50 or outside thereof.

In one example embodiment illustrated in FIG. 12, the swivel member 140 includes several openings 160 for selectively receiving the coupler end 144 and reaction end 134 of first and second links, 112, 114, respectively. The several openings 160 allow for additional adjustment in varying size tanks 12. The construct of the swivel member 140 allows its length to be cut for sizing based on the selection of the openings 160 for the coupler end 144 and reaction end 134 for the particular size and location within the tank 12.

FIG. 7 is a diagrammatical cross-sectional view through part of the system of FIG. 1. Whilst in FIG. 7, the flush valve 16 is shown as a single unit with the housing 50, the arrangement can readily be retrofitted to an existing toilet flushing system with a housing having any number of geometrical configurations.

FIG. 9 illustrates an exploded assembly view of the attachment of the lever 18 to the slide actuator 110, which operates the first link 112 of the control system 100. The pivot arm 32 of the lever 18 passes through an opening 29 located in a spacer 31. The spacer 31 includes a round bearing surface 31A and a square fitting 31B. The bearing surface 31A of the spacer allows rotational movement of the in lever 18 and pivot arm 32 about the opening 29. The spacer 31 is secured to the fixture 30 by a press-fit connection within a square aperture 34 located within the fixture and tank 12. In an alternative example embodiment, the square aperture 34 is a square press-fit in only the tank 12 or fixture 30. The pivot arm 32 is secured to the first lobe 40 in a receiving aperture 41 in cam 38.

In yet an alternative example embodiment, the pivot arm 32 includes a plurality of flats that allow for select positioning in the cam 38 relative to the location of the lever 18 about the tank 12. In the illustrated embodiment of FIG. 9 at least a portion of the pivot arm 32 is hexagonally shaped, allowing for adjustments in 60 degree increments for the lever 18 as its being installed into the tank 12 or fixture 30. The corresponding opening in the receiving aperture 41 is hexagonally shaped to receive the hexagonal pivot arm 32 in the illustrated example embodiment of FIG. 9. The geometrical shape of the pivot arm 32 that includes a plurality of flats also prevents slippage of the pivotal arm 32 within the receiving aperture 41.

Illustrated in FIG. 13 is a plan view of components of the control system 100. In particular, the first and second links, 112, 114 are shown pivotally attached to the swivel member 140. FIG. 13 illustrates axis A-A defining a portion of second link 114 and axis B-B defining the remaining portion of the second link. The first link 112 is defined by an entire axis C-C. Angle θ is formed between the closure end 152 of the second link 114 its midsection 146 as illustrated by angle θ between axis A-A and B-B. Angle θ during operation is between two (2) and ten (10) degrees, and provides improved mobility during the opening of the closure 72 in a high flush operation.

What have been described above are examples of the present invention. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the present invention, but one of ordinary skill in the art will recognize that many further combinations and permutations of the present invention are possible. Accordingly, the present invention is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims.
