OMNI CONFIGURED FLAPPER SYSTEMS AND PACKAGING

BACKGROUND

For the do-it-yourself (DIY) consumer, selecting the correct replacement flapper for a flush valve can be a daunting task. Different manufacturers produce different flush valves for cisterns based on local regulations, manufacturer preferences, or customer requirements. There may be differences between flush valve sizes within a single home or office building. For example, some flush valves may have a 2″ diameter seat, while other flush valve seat diameters may be 3″. Currently, a consumer must know the correct flapper size to purchase before traveling to a store. Additionally, the upper surfaces of seats vary and may be angled or horizontal. However, the consumer may not have realized that such knowledge was necessary, nor how to obtain it, when standing in front of a large selection of flapper choices.

Retail space utilization very important due to its direct impact on operational costs and potential sales revenue. Effective use of retail space can significantly enhance product visibility, customer accessibility, and overall sales. Therefore, retailers and manufacturers continuously seek innovative ways to maximize product display within the limited available space. It is important to achieve this without compromising product protection, information display, and customer interaction.

The size and design of product packaging can greatly influence the quantity of the product that can be displayed in a given space as well as the product's visibility to customers. However, reducing packaging size should not compromise the ability to provide necessary product information, ensure product protection, and facilitate customer interaction.

Therefore, there is a need in the art for a system and/or method that allows for a single flush valve flapper system that fits multiple flush valve sizes. In addition, there is a need for a packaging design that balances the requirements for compactness and space efficiency with the needs for product protection, sufficient information display, and enhanced customer interaction.

SUMMARY

In some embodiments, the disclosure is directed to a flapper system and/or a flapper kit (collectively referred to herein as the flapper system, where a flapper kit can comprise any combination of elements described herein). In some embodiments, the flapper system comprises one or more of a flapper main body, an upper buoyancy dome, a first lower buoyancy dome, a second lower buoyancy dome and one or more mounting arms. In some embodiments, the upper buoyancy dome comprises a protrusion rod. In some embodiments, the flapper main body comprises an open portion configured to enable the protrusion rod to pass therethrough. In some embodiments, the open portion is located along a flapper main body central axis.

In some embodiments, the first lower buoyancy dome is configured to couple to the upper buoyancy dome via the protrusion rod. In some embodiments, the flapper main body is configured to be coupled between the upper buoyancy dome and the first lower buoyancy dome when the flapper system is assembled.

In some embodiments, the flapper main body comprises a main body window configured to enable water and/or air to pass therethrough. In some embodiments, the first lower buoyancy dome comprises a lower dome window configured to enable water and/or air to pass therethrough. In some embodiments, the main body window and the lower dome window cooperate with each other to adjust a water and/or air flowrate through both windows to form an adjustable window. In some embodiments, the upper buoyancy dome comprises a movement (e.g., rotation) engagement portion (top level adjustment) configured to enable a user to move (e.g., rotate) the upper buoyancy dome relative to the flapper main body. In some embodiments, a movement (e.g., rotation) of the upper buoyancy dome relative to the flapper main body causes a relative movement (e.g., rotation) of at least one of the first lower buoyancy dome and second lower buoyancy dome to the flapper main body. In some embodiments, the water and/or air flowrate adjustment is a result of the relative movement (e.g., rotation). In some embodiments, the movement engagement portion comprises an indicator configured to convey a window open position and/or actuation result (e.g., percentage, time).

In some embodiments, the flapper main body is configured to be coupled and/or secured between the upper buoyancy dome and the first lower buoyancy dome when the flapper system is assembled. In some embodiments, the flapper main body comprises a first groove and a second groove. In some embodiments, the first groove is configured to secure a first (e.g., 2″) flush valve seal to the flapper main body. In some embodiments, the second groove is configured to secure a second (e.g., 3″) flush valve seal to the flapper main body. In some embodiments, the first flush valve seal is a different size than the second flush valve seal. In some embodiments, a flush valve seal comprises a seal configured to prevent a flow of water through a cistern flush valve out of a cistern tank.

In some embodiments, each of the one or more mounting arms comprise a first fulcrum and a second fulcrum. In some embodiments, a fulcrum is configured to engage with a mounting ear on a flush valve assembly which serves as a pivot point for lifting the flapper system (e.g., with a chain) to enable the cistern to empty its fluid volume. In some embodiments, the first fulcrum is configured to align a first flush valve seal with a 2 inch flush valve seat to prevent a flow of water out of a cistern. In some embodiments, the second fulcrum is configured to align a second flush valve seal with a 3 inch flush valve seat to prevent the flow of water out of a cistern. In some embodiments, the one or more mounting arms are pivotally mounted to the flapper main body on a pivot. In some embodiments, a pivot point is integral to one or more of the upper buoyancy dome, the flapper main body, or one or more lower buoyancy domes. In some embodiments, the pivot is configured to enable the flapper system to seal either a flat valve or an angled flush valve seat.

In some embodiments, the flapper system comprises a second lower buoyancy dome. In some embodiments, the second lower buoyancy dome is configured to increase a buoyancy of the flapper system greater than the first lower buoyancy dome. In some embodiments, the second lower buoyancy dome is configured to couple to at least one of the upper buoyancy dome, the flapper main body, and the first lower buoyancy dome. In some embodiments, the coupling increases the buoyancy. In some embodiments, the upper buoyancy dome is configured to be mounted to the flapper main body. In some embodiments, a rotation of the upper buoyancy dome adjusts the flowrate of water through both windows. In some embodiments, the flapper system comprises a plurality of windows that allow fluid to enter the first and/or second lower buoyancy dome.

In some embodiments, the upper buoyancy dome comprises an adjustable upper dome including one or more depressed sections and/or one or more raised sections. In some embodiments, the one or more raised sections are configured to increase the amount of air within the adjustable upper dome. In some embodiments, the one or more depressed sections are configured to decrease an amount of air underneath the adjustable upper dome.

In some embodiments, the adjustable upper dome is configured to be rotated such that the one or more raised sections are distal from the one or more fulcrums, such that the one or more raised sections are higher than the one or more depressed sections when the flapper system is rotated about the one or more fulcrum mounts (e.g., when lifted by the chain). In some embodiments, the one or more raised sections being higher than the one or more depressed sections is configured to enable the raised section to be above the one or more air bleeds resulting in the trapping of air in the one or more raised sections by water below the one or more raised sections. In some embodiments, the one or more raised sections being higher than the one or more depressed sections and/or the one or more air bleeds is configured to cause the flapper system to remain raised a longer time during a flushing operation than when the one or more depressed sections are higher than the one or more raised sections.

In some embodiments, the adjustable upper dome is configured to be rotated such that the one or more depressed sections are distal from the one or more fulcrums, such that the one or more depressed sections are higher than the one or more raised sections when the flapper system is rotated about the one or more fulcrum mounts (e.g., when lifted by the chain). In some embodiments, the one or more depressed sections being higher than the one or more raised sections is configured to cause fluid to become trapped in the one or more raised portions. In some embodiments, the fluid becomes trapped due to the one or more raised portions being below one or more air bleeds which allows air to escape the one or more raised sections which results in the one or more raised sections flooding with fluid when the flapper system is raised during a flushing operation. In some embodiments, the one or more depressed sections being higher than the one or more raised sections is configured to cause the flapper system to remain raised for a shorter time during a flushing operation than when the one or more depressed sections are lower than the one or more raised sections during a flushing operation.

In some embodiments, the adjustable upper dome is configured to be adjustable such that at least a portion of the depressed section and at least a portion of the raised section is distal from the one or more fulcrum mounts.

The subject matter described herein are directed to technological improvements to the field of flush valve flapper replacement by providing a single system that can replace the flappers for different flush valve seat types. Indeed, the systems and methods described herein were unknown and/or not present in the public domain at the time of filing, and they provide a technologic improvements advantages not known in the prior art. Furthermore, the system includes unconventional steps that confine the methods described herein to a useful application.

It is understood that the system is not limited in its application to the details of construction and the arrangement of components set forth in the previous description or illustrated in the drawings. The system and methods disclosed herein fall within the scope of numerous embodiments. The previous discussion is presented to enable a person skilled in the art to make and use some embodiments of the system. Any portion of the structures and/or principles included in some embodiments can be applied to any and/or all embodiments: it is understood that features from some embodiments presented herein are combinable with other features from some other embodiments. As a non-limiting example, the upper buoyancy dome 2 in FIG. 2 can be replaced with the adjustable upper dome 51 in FIG. 24 and still fall within the disclosure according to some embodiments. Thus, some embodiments of the system are not intended to be limited to what is illustrated but are to be accorded the widest scope consistent with all principles and features disclosed herein, where the term “in some embodiments” or “according to some embodiments” as used herein means features from one figure or section of the disclosure are readily incorporable with features from another figure or section of the disclosure.

Some embodiments of the system are presented with specific values and/or setpoints. These values and setpoints are not intended to be limiting and are merely examples of a higher configuration versus a lower configuration and are intended as an aid for those of ordinary skill to make and use the system. For example, reference to a 2″ valve and a 3″ valve seat can be replaced with more general language such as “first” and “second” valve seat when defining the metes and bounds of the system.

Furthermore, acting as Applicant's own lexicographer, Applicant imparts the explicit meaning and/or disavow of claim scope to the following terms:

Applicant defines any use of “and/or” such as, for example, “A and/or B,” or “at least one of A and/or B” to mean element A alone, element B alone, or elements A and B together. In addition, a recitation of “at least one of A, B, and C,” a recitation of “at least one of A, B, or C,” or a recitation of “at least one of A, B, or C or any thereof” are each defined to mean element A alone, element B alone, element C alone, or any of elements A, B and C, such as AB, AC, BC, or ABC, for example.

“Substantially” and “approximately” when used in conjunction with a value encompass a difference of 5% or less of the same unit and/or scale of that being measured.

As used herein, “can” or “may” or derivations there of (e.g., the system can perform X) are used for descriptive purposes only and is understood to be synonymous and/or interchangeable with “configured to” (e.g., the flapper is configured to perform X) when defining the metes and bounds of the system.

In addition, the term “configured to” means that the limitations recited in the specification and/or the claims must be arranged in such a way to perform the recited function: “configured to” excludes structures in the art that are “capable of” being modified to perform the recited function but the disclosures associated with the art have no explicit teachings to do so. For example, a recitation of a “container configured to receive a fluid from structure X at an upper portion and deliver fluid from a lower portion to structure Y” is limited to systems where structure X, structure Y, and the container are all disclosed as arranged to perform the recited function. The recitation “configured to” excludes elements that may be “capable of” performing the recited function simply by virtue of their construction but associated disclosures (or lack thereof) provide no teachings to make such a modification to meet the functional limitations between all structures recited. The recitation “configured to” can also be interpreted as synonymous with “operatively connected” when used in conjunction with physical structures.

It is understood that the phraseology and terminology used herein is for description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.

The previous detailed description is to be read with reference to the figures, in which like elements in different figures have like reference numerals. The figures, which are not necessarily to scale, depict some embodiments and are not intended to limit the scope of embodiments of the system. It is understood that the drawings are part of the disclosure and that words and phrases used to describe the drawings when defining the metes and bounds of the system do not need verbatim support in the specification so long as the language is supported by the drawings.

Although method operations are presented in a specific order according to some embodiments, the execution of those steps do not necessarily occur in the order listed unless a explicitly specified.

It will be appreciated by those skilled in the art that while the invention has been described above in connection with particular embodiments and examples, the invention is not necessarily so limited, and that numerous other embodiments, examples, uses, modifications and departures from the embodiments, examples and uses are intended to be encompassed by the claims attached hereto.
