Abstract
A metering faucet includes a housing and a faucet metering cartridge positioned within the housing and having an outwardly extending faucet stem which is movable along a stem axis. There is a cartridge cap which is positioned within the housing and has a portion extending over and in contact with the cartridge stem to provide an inward force thereon. A handle is pivotally mounted to the housing on one side of the stem axis, with the handle having a portion which extends through a housing opening to contact the cartridge cap. Upon pivotal movement of the handle, an inward force is applied on the cartridge stem. The handle has a force applying area which extends a substantial distance from the pivotal mounting of the handle and terminates at the diametrical opposite side of the pivotal mounting of the handle.
Description
- The present invention relates to metering faucets of the type commonly found in commercial washrooms, and more specifically, to a metering faucet in which the handle is designed to provide the optimum mechanical advantage for the individual operating the faucet. Many present-day metering faucets of the type commonly found in public washrooms require a substantial application force to cause water to flow from the faucet. To be consistent with the Americans with Disabilities Act, such faucets should provide a handle or lever which minimizes the force required to operate the faucet. The present invention is directed toward that end, and further provides a metering faucet which has minimum components and the optimum mechanical advantage, implemented with an aesthetically pleasing handle style.
- The present invention relates to metering faucets and in particular to such a faucet which has a minimum number of components and the maximum or optimum mechanical leverage for operating the faucet.
- A primary purpose of the invention is to provide a faucet as described in which the handle extends a substantial distance from its point of pivotal attachment to maximize the mechanical advantage upon operation of the handle.
- Another purpose of the invention is to provide a metering faucet as described which has an aesthetically pleasing handle, but one which utilizes its shape to provide maximum mechanical advantage in operation of the faucet.
- Other purposes will appear in the ensuing specification, drawings and claims.
- The invention is illustrated diagrammatically in the following drawings wherein:
- FIG. 1 is a partial axial section through a metering faucet as described herein;
- FIG. 2 is a bottom view of the faucet handle;
- FIG. 3 is a section along plane3-3 of FIG. 2;
- FIG. 4 is a top view of the cartridge cap;
- FIG. 5 is a section along plane5-5 of FIG. 4; and
- FIG. 6 is a top view of the faucet housing.
- The present invention relates to metering faucets and utilizes a commercially available metering cartridge which is shown in U.S. Pat. No. 4,659,059, which is herein incorporated by reference. This cartridge is sold by Acorn Manufacturing Company under part number 2302-000-003, but the invention should not be limited to this specific type of metering cartridge. What is required is a cartridge which has its own effective return spring or return mechanism.
- In the drawings, the faucet housing is indicated generally at10 and includes a slightly frusto-
conical portion 12, with acylindrical portion 14 at its upper end. Thecylindrical portion 14 is covered by atop 16 having acentral opening 18. Positioned within thehousing 10 and held therein by acartridge nut 20 is afaucet cartridge 22 having an outwardly-extending axiallymovable stem 24. Thestem 24 will move along anaxis 26, as it is operated by thehandle 28. - Positioned inside of the
cylindrical portion 14 of thehousing 10 is acartridge cap 30 which has acylindrical wall 32, with acorner opening 34, as particularly shown in FIG. 5. The opening 34 accommodates aboss 36 integrally formed as a part of thehousing 10. The cartridge cap is movable within thecylindrical portion 14 of the housing in response to movement of thehandle 28. - The
handle 28 is pivotally attached to thehousing 10 by means of apin 38 which extends through abore 40 in theboss 36 and through alignedopenings 42 in thehandle 28. It should be noted that the pivotal connection of the handle to thehousing 10 is on one side of theaxis 26 along which thecartridge stem 24 will move during operation of the faucet. - The
handle 28 has acavity 44 within which is positioned aprojection 46 which, as shown particularly in FIG. 1, is slightly offset from theaxis 26 toward the pivotal connection of the handle to the housing. The upper end of thehousing 10 and theboss 36 are partially located within thecavity 44, as particularly shown in FIG. 1. - The
handle 28 has ahandle extension 48 which extends away from the pivotal connection of the handle to the housing and is diametrically opposed or on the opposite side of the handle pivotal mounting to the housing. This particular configuration of the handle, taken in combination with the slightlyoffset projection 46, provides maximum leverage when thehandle portion 50 is given a downward force to operate the faucet. This provides maximum leverage for the force applied to thehandle area 50. - In operation, a force applied in the
area 50 will cause the handle to pivot aboutpin 38 and force theprojection 46 to slide upon theupper cam surface 52 at the top of the cartridge cap to apply a downward force to thecartridge stem 24. Thecam surface 52 has its highest point or the top of its ramp offset toward the pivotal connection of the handle to maximize the force delivered byprojection 46 on the cartridge cap. As theprojection 46 slides on thecam surface 52, it will apply sufficient downward force to cause the handle to pivot to a degree about thepin 38 to cause the cartridge stem to move inward. The motion will be reversed when the handle is released and the mechanism within the cartridge provides a return force for the handle. The return force may be from a return spring in the cartridge, fluid under pressure within the cartridge, and inlet water pressure. - Of particular advantage is the relationship between the pivotal mounting of the handle, the extension of the handle force receiving to an area a substantial distance away from that pivotal mounting, and the cooperation between the
projection 46, the cam surface on top of the cartridge cap, and the cartridge cap itself. All of these elements, in combination, and in the particular configuration shown and described, are designed to provide the optimum mechanical advantage for operation of the faucet. - Whereas the preferred form of the invention has been shown and described herein, it should be realized that there may be many modifications, substitutions and alterations thereto.
