The present invention relates generally to the field of faucet cartridge removal tools, and more particularly, to a faucet cartridge removal tool configured to linearly move, engage, and remove a faucet cartridge about a single axis with limited movement (e.g., lateral movement) of the tool and/or cartridge outside of the single axis, thus preventing and/or limiting accidental breakage of the faucet cartridge during removal from a faucet valve.
Faucet cartridges are included in faucets (e.g., sink and shower faucets) to regulate water flow and temperature. In essence, a faucet cartridge is the entire basis for the faucet's function—containing a rocker switch capable of blocking off or opening both hot and cold water lines entirely, as well as to varying degrees. For example, when the faucet lever (not shown) is raised to turn water on, the cartridge is pushed forward within faucet valve, causing both water lines to unblock. When the faucet lever is pushed down, both water lines are blocked entirely, turning off the water flow from the faucet. When centered, the faucet cartridge allows water from both lines (hot and cold water lines) to pass equally. When pressed to the left, the cartridge allows more water from the hot line pass than the cold line until the cold line is blocked entirely. Similarly, when pressed to the right, the cartridge allows more water from the cold line to pass than the hot line until the hot line is blocked entirely, thus allowing the faucet user to vary water temperature as desired.
In view of the above faucet and valve description,
When replacing worn out faucet cartridges, specialized tools such as the conventional faucet cartridge removal tool 10 shown in
Although conventional faucet cartridge removal tool(s) 10 are somewhat effective for removing faucet cartridge(s) 200 from valve 300, several problems frequently occur when using tool 10 to remove these cartridges 200. For example, when forcibly removing cartridge 200 with tool 10 from valve 300, tool 10 fails to limit lateral movement (or side to side motion) in direction D3 relative to the tool's longitudinal axis. Because this lateral movement (or side to side motion) is not limited or completely eliminated by tool 10, the tool user frequently breaks stem 201, main body 202, and/or threaded portion 14 during cartridge removal, which in turn further complicates an already complicated cartridge removal process. Therefore, a need exists to provide a more effective cartridge tool that avoids the above mentioned problems frequently observed with conventional faucet cartridge removal tool(s).
It is an object to provide a more effective faucet cartridge tool that avoids the problems frequently observed with conventional faucet cartridge removal tool(s). Thus, disclosed is a faucet cartridge removal tool that limits lateral movement of the tool and faucet cartridge during faucet cartridge removal. The tool includes (a) a hollow cylindrical main body configured to seat on a faucet valve or faucet cartridge lip to limit lateral movement of the tool while in use, the hollow cylindrical main body having one or more windows formed thereon for viewing engagement between the tool and faucet cartridge while in use; (b) a first movement member partially housed within the hollow cylindrical main body and configured to move about a single linear axis (A1) above and below the hollow cylindrical main body relative to a longitudinal axis (L1) of the tool while in use, the first movement member comprises (i) a rod partially housed within the main body and viewable through one or more windows of the hollow cylindrical main body, (ii) a handle positioned on one end of the rod that is configured to selectively move the solid rod within the main body in a first direction (D1) about the single linear axis (A1), and (iii) a faucet cartridge engagement member positioned on a second end of the rod that is configured to fixedly engage the faucet cartridge during faucet cartridge removal; and (c) a second movement member that is configured to move the rod in a second direction (D2) about the single linear axis (A1) that is opposite the first direction (D1) to remove the faucet cartridge during faucet cartridge removal while concurrently maintaining engagement between the faucet cartridge engagement member and faucet cartridge and limiting lateral movement of the tool.
In certain aspects, the rod rotationally moves in a clockwise manner about the single linear axis in the first direction when advancing the rod through the main body.
In certain aspects, the engagement member includes a threaded portion configured for engagement within a threaded inner diameter of a stem of the faucet cartridge.
In certain aspects, engagement member extends below the solid rod of the first member and has a smaller outer diameter (OD2) than the outer diameter (OD) of the rod (solid rod), the outer diameter (OD2) of the engagement member is at least partially threaded along its length and configured for engagement within a threaded inner diameter of a stem of a faucet cartridge.
In certain aspects, the second movement member is positioned between the handle and hollow cylindrical main body.
In certain aspects, a portion of the rod of the first movement member is enclosed within the second movement and circumferentially engaged with the second movement member such that the rod may be moved in a second direction about the single linear axis that is opposite the first direction to remove the faucet cartridge during faucet cartridge removal while concurrently maintaining engagement between the faucet cartridge engagement member and cartridge and limiting lateral movement of the tool.
In certain aspects, the engagement member is attached to a bottom of the rod and extends below the rod of the first member in a direction away from the tool and has a smaller outer diameter (OD2) than an outer diameter (OD1) of the rod (solid rod), the outer diameter of the engagement member is completely threaded along its length and configured for engagement within a threaded inner diameter of a stem of a faucet cartridge such that the bottom of the rod is flush with and adjacent to an outermost surface of the faucet cartridge when the engagement member is completely engaged with the faucet cartridge.
In certain aspects, the handle is transverse relative to the longitudinal axis of the tool and extends beyond the outer most surfaces of the second movement member and hollow cylindrical main body to facilitate a user's ease of gripping and operating the tool.
In certain aspects, the handle is substantially “T” shaped.
In certain aspects, also disclosed is a kit comprising the faucet cartridge removal tool disclosed in any of the above aspects. For example, the faucet cartridge removal tool included within the kit includes (a) a hollow cylindrical main body configured to seat on a faucet valve or faucet cartridge lip to limit lateral movement of the tool while in use, the hollow cylindrical main body having one or more windows formed thereon for viewing engagement between the tool and faucet cartridge while in use; (b) a first movement member partially housed within the hollow cylindrical main body and configured to move about a single linear axis (A1) above and below the hollow cylindrical main body relative to a longitudinal axis (L1) of the tool while in use, the first movement member comprises (i) a rod partially housed within the main body and viewable through one or more windows of the hollow cylindrical main body, (ii) a handle positioned on one end of the rod that is configured to selectively move the solid rod within the main body in a first direction (D) about the single linear axis (A1), and (iii) a faucet cartridge engagement member positioned on a second end of the rod that is configured to fixedly engage the faucet cartridge during faucet cartridge removal; and (c) a second movement member that is configured to move the rod in a second direction (D2) about the single linear axis (A1) that is opposite the first direction (D1) to remove the faucet cartridge during faucet cartridge removal while concurrently maintaining engagement between the faucet cartridge engagement member and faucet cartridge and limiting lateral movement of the tool.
