TOILET FLUSH ARM COUPLERCROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit and priority to U.S. Provisional Application No. 63 / 609,995, filed December 14, 2023, which is hereby incorporated herein by reference in its entirety for all purposes.FIELD OF THE DISCLOSURE
[0002] Some embodiments of the present disclosure relate generally to a toilet tank comprising a flush valve which has a chain or other coupler that is used to activate the toilet flush mechanism, and which has an adjustable length. Some embodiments for making the coupler length adjustment easier are also described.BACKGROUND
[0003] Typical toilet tanks have a flush valve with a flapper and a chain attached to the top of the flapper (FIG. 1). The other end of that chain is connected to the flush arm by a chain clip. When the flush lever actuator is activated by a user to flush the toilet, the flush arm moves up, pulling the chain to lift the flapper and allow water in the toilet tank to discharge and flow to the toilet bowl. Setting the proper flapper chain length to have the right amount of slack is very important to enable a trouble-free toilet flush actuation and the resetting of the flush valve flapper after the flush. A chain that has an end hanging freely can block the flapper from sealing, causing a large increase in water usage.
[0004] Typically, the flapper chain is connected to the flush arm with a chain clip (FIG. 2A & 2B). The chain clip is inserted into a chosen chain link of the flapper chain and that link is routed to settle at the bottom eyelet of the chain clip. The chain clip is then attached to the flush arm via clipping into a hole on the flush arm. When adjusting the chain length to ensure it is tight enough to lift the flapper, the hanging end of the chain becomes longer. This longer chain can interfere with the flushing mechanism by potentially tangling with or obstructing other components within the toilet tank.
[0005] To change the chain length setting, as is necessary to obtain the proper chain slack for the flush valve flapper to function correctly, the chain clip must first be removed from the flush arm.Then the current chain link on the chain clip is routed to be removed from the chain clip. And the process repeats for selecting a new chain link to attach to the chain clip, to either lengthen or shorten the current undesired chain length. This iterative process is cumbersome and can be difficult in some situations where there is limited space to freely access the flush arm. Often, the repeated installation and removal of the chain clip on and off the flush arm can damage the chain clip as it is commonly constructed from small, formed wire and can be easily deformed.
[0006] Therefore, there is a need in the art for a better way to adjust the flapper coupler length.SUMMARY

[0026] In some embodiments, the system is directed to a kit comprising two or more chain clips and a flapper chain. In some embodiments, the kit comprises one or more of a flush valve, a flush lever arm, a flush handle, and a flush flapper. In some embodiments, the kit includes a flush valve.
[0027] In some embodiments, the kit includes a flush lever. In some embodiments, the flush lever is configured to facilitate the flushing process by engaging with a flush valve. In some embodiments, the kit includes a flush valve. In some embodiments, the flush valve is configured to control the flow of water from the tank to the bowl during a flush.
[0028] In some embodiments, the kit includes a flapper. In some embodiments, the flapper is configured to seal the tank and lift to allow water to flow into the bowl when the toilet is flushed. In some embodiments, the kit includes a chain (e.g., metal or plastic) configured to enable a chain clip to be attached thereto. In some embodiments, the chain and clip are configured to connect the flapper to the flush lever, enabling the movement of the flapper during flushing.
[0029] In some embodiments, the kit includes a handle. In some embodiments, the handle is configured to activate a fill valve when pressed. In some embodiments, the kit includes a fill valve. In some embodiments, the fill valve is configured to regulate the water level in the tank, refilling it after each flush. In some embodiments, the kit includes a dual-flush mechanism. In some embodiments, the dual-flush mechanism is configured to allow for two different flush volumes, providing water efficiency. In some embodiments, the kit includes a repair kit. In some embodiments, the repair kit includes one or more of the flush valve, fill valve, flapper, handle, chain, lever, and / or any flush assembly parts. In some embodiments, the kit includes at least two chain clips. In some embodiments, the two chain clips are identical.
[0030] In some embodiments, the system comprises one or more of a flush lever arm, a flapper chain, and one or more chain clips. While a chain and chain clip are referenced herein for nonlimiting, illustrative purposes, other couplers including cables, ties, and the like can also be used in accordance with some embodiments. In some embodiments, a method step includes threading the flapper chain open end through the chain clip neck open section (FIG. 3 A). Some embodiments include a method step of choosing the chain link to attach the chain clip (see FIG. 3B).
[0031] In some embodiment, the flapper chain is comprised of chain links having a round or oval shape. In some embodiment, the chain clip is formed from wire with a round, oval, square, or rectangular cross-section. In some embodiment, the chain clip neck portion and / or bottom eyelet is configured to secure (i.e., fit snugly, with small clearance) the chain to the chain clip by orienting a first chain link to fit in the neck portion (and / or bottom eyelet), where the orientation of the first chain link by the chain clip orients adjacent chain links such that they cannot pass through the chain clip neck portion and / or bottom eyelet, as best shown in FIG. 3C.
[0032] In some embodiments, the chain clip includes a hook portion opposite the bottom eyelet configured to hook onto an arm aperture of the flush arm, such that the chain clip hangs from the arm aperture at a top of the hook portion under the force of gravity. In some embodiments, an end of the hook portion includes a bent hook end, which may fit through a link in the chain to thread the chain clip to the chain link. In some embodiments, the bent hook end cooperates with a bent portion of a neck chain trap to create a hook chain trap. In some embodiments, the hook chain trap can be forced open for a chain link to pass through, and / or closes under spring force to keep the chain contained in the hook portion and / or hook open section. In some embodiments, the chain clip is configured to enable secure engagement with the chain by enabling a threading of one or more chain links into the hook portion and / or threading the chain through the hook open section.
[0033] In some embodiments, a lower portion of the hook open section is defined by a neck trap bend. In some embodiments, the neck trap bend also forms a top portion of a neck open section which is sized to enable a chain to be threaded therethrough. In some embodiments, the neck chain trap is configured to prevent the chain from entering the hook portion area until an end of the neck chain trap is pulled a sufficient distance to allow at least one chain link to pass.
[0034] Some embodiments include a method step of pulling the chain down so the chosen chain link will snap into the neck of the chain clip at the bottom eyelet (FIG. 3C), which holds the flapper chain in a secured position. Some embodiments include a method step of attaching the chain clip to the flush arm by clipping the chain clip into an aperture on the flush arm.
[0035] In some embodiments, to change the set length of the flapper chain, a method step includes not removing the chain clip off the flush arm. Some embodiments include a method step of pulling the flapper chain up to unsnap the chain link from the neck of the chain clip at the bottom eyelet (FIG. 4A). In some embodiments, once the chain link is released, a method step includes shortening or lengthening the flapper chain by sliding the flapper chain relative to the chain clip (FIG. 4B) and choosing a new chain link. Some embodiments include a method step of pulling the flapper chain down again to snap the new chosen chain link into the neck and / or eyelet (FIG. 4C).
[0036] In some embodiments, if the chain is too long (e.g., more than 10 chain links), a method step includes cutting or otherwise shortening the flapper chain so it does not tangle and impede the proper functioning of the flapper valve during or after the toilet flush.
[0037] In some embodiments, the system includes a second chain clip. Some embodiments include a step of attaching the second chain clip to a chain end section link (e.g., the last or second to lastlink of the flapper chain) as shown in FIG. 5. In some embodiments, a step includes threading the second chain clip and attached flapper chain through the first chain clip neck open section, as also illustrated in FIG. 5.
[0038] Some embodiments include attaching (e.g., clipping) the second chain clip to the flush arm via a same or different arm aperture on the flush arm as depicted in FIG. 6. This way, the excess flapper chain hanging between the first and second chain clip can be kept close to the flush arm and prevented from interfering with the flapper, eliminating the need to use a tool to cut the excess flapper chain to a shorter length.
[0039] Some embodiments include a method step of attaching the second chain clip to the flapper chain by passing a chain end section link (e.g., the last or second to last link of the flapper chain) through the neck open section as shown in FIG. 7. Some embodiments include a step of pressing the end section link down into the neck and / or eyelet, which is configured to hold the chain in a secured position as shown in FIG. 8. In some embodiments, a method step includes threading the second chain clip and attached flapper chain through the first chain clip neck open section similar to the methods described above.
