DETAILED DESCRIPTION

[0008] The following detailed embodiments presented herein are for illustrative purposes. That is, these detailed embodiments are intended to be exemplary of the present invention for the purposes of providing and aiding a person skilled in the pertinent art to readily understand how to make and use of the present invention.

[0009] Accordingly, the detailed discussion herein of one or more embodiments is not intended, nor is to be construed, to limit boundaries of the patent protection afforded the present invention, in which the scope of patent protection is intended to be defined by the claims and equivalents thereof. Therefore, embodiments not specifically addressed herein, such as adaptations, variations, modifications, and equivalent arrangements, should be and are considered to be implicitly disclosed by the illustrative embodiments and claims described herein and therefore fall within the scope of the present invention.

[0010] Further, it should be understood that, although steps of various claimed methods may be shown and described as being in a sequence or temporal order, the steps of any such method are not limited to being carried out in any particular sequence or order, absent an indication otherwise. That is, the claimed method steps are considered capable of being carried out in any sequential combination or permutation order while still falling within the scope of the present invention.

[0011] Additionally, it is important to note that each term used herein refers to that which a person skilled in the relevant art would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein, as understood by the person skilled in the relevant art based on the contextual use of such term, differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the person skilled in the relevant art should prevail.

[0012] Furthermore, a person skilled in the art of reading claimed inventions should understand that a and an each generally denotes at least one, but does not exclude a plurality unless the contextual use dictates otherwise. Also, the term or denotes at least one of the items, but does not exclude a plurality of items of the list.

[0013] This disclosure teaches a kit of parts or components for rebuilding, repairing, or replacing parts of a faucet cartridge for a single handle faucet in an existing faucet installation. In a faucet installation consisting of original manufacturer's equipment, the valve of the faucet installation conventionally has an upstanding valve stem the upper end portion of which is of non-circular, transverse cross-sectional configuration, with an underface of the faucet handle having a bore of complementary length and complementary transverse cross-sectional configuration and dimensions, so that with the upper end portion of the faucet valve stem disposed within the bore in the handle the handle is non-rotatably mounted at a pre-determined level on the valve stem and turning of the faucet handle results in turning of the valve stem and hence opening or closing of the faucet valve. The upper end portion of the faucet valve stem is generally of cylindrical form with the bore in the faucet handle being of corresponding length and cylindrical form.

[0014] Through use of the single handle faucet installation over an extended period of time, components of the faucet may become broken or otherwise damaged and this necessitates replacement of the faucet handle, unless of course the entire faucet valve and handle are replaced which is more expensive and in many cases unnecessary.

[0015] It is accordingly a primary object of the present invention to provide at least one replacement part to repair a single handle faucet cartridge. In accordance with the present invention there is provided a kit of parts which comprises components for rebuilding or repairing a single handle faucet cartridge comprising a bonnet nut, an upper assembly comprising an outside body, a roll pin, a stem, and a stem cam, an engagement disc, a upper disc not comprising holes, a lower disc comprising holes, a lower seal assembly comprising a bottom seal retainer and a bottom seal, and a handle screw, wherein the handle screw comprises threading.

[0016] The general inventive concept is not intended to be limited to the specific embodiments illustrated herein.

[0017] FIG. 1 is an exploded view of a single handle faucet cartridge rebuilding kit according to one embodiment of the present disclosure. As shown in FIG. 1, the exemplary single handle faucet cartridge repair kit 10 comprises a bonnet nut 12, outside body 14, a stem 16, a roll pin 18, and a stem cam 20. The stem cam 20 is top-hat shaped, wherein a bottom portion 22 of the stem cam 20 is flat and wider than a top portion 24, and the top portion 24 includes a through bore 26 that accepts a bottom portion 28 of the stem 16. The single handle faucet cartridge repair kit 10 further comprises an engagement disc 32 and an upper disk 34 that does not comprise holes or throughbores. The single handle faucet cartridge repair kit 10 may comprise an engagement disc 32 where the upper disc 34 is permanently attached to the engagement disc 32 or is removably attached to the engagement disc 32.

[0018] The single handle faucet cartridge repair kit 10 also comprises a lower disc 36, a bottom seal 38, and a bottom seal retainer 40. The lower disc 36 can comprise at least one hole or throughbore. The bottom seal 38 can be made out of rubber or another material that acts as a seal. The bottom seal 38 and bottom seal retainer 40 each include at least one hole, and preferably 3 holes. The bottom seal 38 can be nearly circular in shape. The bottom seal 38 is comprised of two flat sides, the flat sides being positioned opposite one another. The bottom seal 38 can also be seated inside the bottom seal retainer 40.

[0019] The components of the single handle faucet cartridge repair kit 10 can be made from hard materials that resist wear from use. Some examples of hard materials comprise metal, stainless steel, plastic, nylon, ceramic, or combinations thereof, though this list is not exhaustive. A person having ordinary skill in the art of repairing at least one broken component of a single handle faucet cartridge would understand what materials can be used to make the components of the single handle faucet cartridge repair kit 10.

[0020] Turning to FIG. 2 the single handle faucet cartridge repair kit 10 can further comprise, optionally, a wrench 42, a handle screw 44, and lubricant 46. The wrench 42 can be a hex key wrench and the lubricant 46 can be a silicone lubricant.

[0021] Turning to FIG. 3, the back side of the upper disc 34 is shown. The back side of the upper disc 34 comprises a slot 48. The slot 48 does not create a bore through the upper disc 34.

[0022] Turning to FIG. 4, the back side of the lower disc 36 is illustrated.

[0023] To install any components of the single handle faucet cartridge repair kit 10 disclosed herein, the existing faucet handle will need to be removed first to expose the faucet cartridge contained therein. The existing cartridge and its components will have to be removed and analyzed to identify the malfunctioning component or components. Once at least one component is identified as malfunctioning, that component can be replaced by the corresponding component contained in the single handle faucet cartridge repair kit 10 described herein. If more than one component is malfunctioning, a plurality of components contained in the single handle faucet cartridge repair kit 10 can be used to replace the more than one damaged or broken part.

[0024] It is recognized that similar modifications can be made to single handle faucet cartridge rebuilding kit to aid in fixing a malfunctioning single handle faucet that are not specifically set forth herein. To the extent that any such variations do not materially change the design and/or function of the kit 10 as described, they are considered to be within the spirit and scope of the disclosure as defined in the claims.
