Abstract

A faucet handle mechanism for attaching a faucet handle to a faucet valve body, which valve body has a rotatable valve stem, includes an adapter coaxial with and attached to the valve stem for concurrent rotation with the stem. There is an insert coaxial with and attached to the adapter for concurrent rotation with the insert and stem. A handle is coaxial with and attached to the insert for concurrent rotation with the insert, adapter and valve stem. A fastener secures the adapter, insert and handle together. There is a generally cylindrical chassis coaxial with and extending about the adapter, with the chassis being non-rotatably attached to the valve body. A shell is non-rotatably mounted on the chassis, with the chassis having an upper bearing surface which rotatably supports a lower bearing surface on the insert. The chassis and adapter have cooperating elements which prevent relative axial movement therebetween.

    • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • FIG. 1 illustrates a faucet assembly commonly known in the trade as a two handle widespread and which includes a centrally located [0038] spout 10 and a right side or cold water faucet handle 12 and a left side or hot water faucet handle 14. The handle 14 is shown in exploded perspective form. Extending upwardly through the faucet deck 16 is a faucet valve body 18 having a valve operating stem 20. Rotation of the stem 20 controls the volume of water, from the hot side, flowing through the spout 10.
  • The components of the faucet handle mechanism are particularly shown in FIG. 1. There is an [0039] escutcheon 22 which will extend about the valve body and a handle shell 24, which is seated on top of the escutcheon. There is an adapter 26, a wave washer 28, and a handle chassis 30. The wave washer will be positioned between facing surfaces of the adapter and a handle insert 32. The handle is indicated at 34 and there is a handle cap 36. The components just described are shown in assembled form in the section of FIG. 2.
  • As indicated above, the [0040] escutcheon 22 is seated on the sink deck and the shell 24 is seated on top of the escutcheon and forms a portion of the faucet handle exterior, and with the handle 34 and the handle cap 36 defines the overall appearance and usable components for the faucet handle.
  • The [0041] adapter 26 has an interior bore 38 with a series of uniformly spaced splines 40, illustrated in FIG. 8. The splines 40 on the adapter interact with the splined exterior 42 on the valve stem 20. Thus, the adapter will drive or turn the valve stem.
  • The [0042] chassis 30 has an interior bore 44 with a threaded portion 46, which threaded portion engages the exterior threads 48 on the valve body 18. The chassis 30 is thus threadedly attached to the valve body.
  • The exterior of the [0043] chassis 30 has a plurality, in this case four, uniformly spaced axially extending projections 50 which will interact with the interior of the shell 24. As shown specifically in FIGS. 3 and 4, the interior of the shell 24 has four pairs of spaced ribs 52, with each pair of ribs defining a slot 54, which slots will receive the projections 50 providing a non-rotatable connection between the shell 24 and the chassis 30.
  • The exterior of the [0044] adapter 26, generally intermediate its opposite ends, has a ledge 56 which is above a series of projections 58 which define a series of uniformly sized grooves 60. When the chassis 30 is positioned coaxial with and exteriorly of the adapter 26, the inwardly extending annular shoulder 62 of the chassis extends directly above the ledge 56. Thus, the adapter 26 is attached to and rotatable with the valve stem and the chassis 30 prevents relative axial movement between the adapter and the valve stem. The upper surface of the shoulder 62 will form a bearing surface for rotary movement of the handle insert 32.
  • As shown particularly in FIG. 2, the [0045] handle insert 32 is in driving engagement with the adapter 26 and has a lower bearing surface 64 formed by a flange 66 which rides on the shoulder 62 of the chassis 30. The interior of the insert 32, as shown in FIGS. 12-15, has a chamber 68 with a series of inwardly directed projections 70 which form a plurality of uniformly spaced grooves 72 and a non-uniform projection. These grooves and projections interact with mating grooves and projections 76 and 78 on the exterior of the adapter 26 to form the driving connection between these two elements. The non-uniformity of the projections and grooves assures proper alignment of these two elements.
  • The [0046] insert 32 has an upwardly extending annular shoulder 80 which defines an interior space 82 having a series of projections 84 defining a plurality of uniformly spaced grooves 86 and a non-uniform groove 88. These grooves and projections will interact with the interior boss 90, shown in FIG. 17, of the cap 34. As particularly shown in FIG. 18, the exterior of the boss 90 has projections 92, one of which, at 94, is of non-uniform size, and grooves 96, to thereby form a driving connection between the handle and the insert 32. The assembly of the adapter, insert and handle are secured together by a fastener 98 which extends through the upper portion of the adapter, through the handle insert, through the boss 90 of the handle 34 and into a bore 100 formed in a central boss 102 of the cap 36. The fastener 98 secures the cap to the handle and attaches all of the rotatable elements together, thus providing a faucet handle mechanism in which there is no visible means of securing the mechanism to the faucet valve stem. The cap boss 102 includes three projections 101 which seat in slots 103 in the handle 34 to assure proper orientation of these elements.
  • The faucet shown in FIGS. [0047] 22-32 is commonly known in the trade as a mini widespread, and the principal difference between this embodiment of the invention and that shown in FIGS. 1-21, is that the stem of the valve does not have exterior splines, but rather has what is known as a D-shaped cross section. The faucet valve body is indicated at 110 and the rotatable valve stem is shown at 112. The adapter 114 has an interior bore 116 of the same D-shaped cross section as the valve stem 112 and thus the adapter forms the drive connection between the handle and the valve stem. The exterior of the adapter 114 has a series of outwardly-extending projections 118, shown in FIGS. 27 and 28, which function in the manner of the FIG. 1-21 embodiment to interengage the adapter 114 with the insert 120. The insert 120, as in the earlier embodiment, has an upwardly facing interior opening 122 with a series of projections 124 which will interact with projections and grooves on the boss 126 of the handle 128. The construction is similar to that in the first embodiment. A fastener 130 will attach the adapter, insert and handle by extending into the bore of the handle cap 132.
  • The [0048] chassis 134 again has a series of axially extending projections 136 which will interact with the slot 138 formed between adjoining pairs of ribs 140, again as in the FIG. 1-21 embodiment. Thus, the chassis and the shell 142 are joined together, prohibiting rotation therebetween.
  • The [0049] chassis 134 extends over the adapter 114 and has an inwardly-directed annular projection 144 which is seated on an outwardly-extending flange 146 of the adapter when the faucet handle mechanism is assembled as shown in FIG. 23. In this manner, the adapter 118 is prevented from axial movement relative to the valve stem 112. The insert 120 has an annular shoulder 148, the lower surface of which will ride on the upper surface 150 of the chassis 134 providing the same rotatable bearing surfaces as in the FIG. 1-21 embodiment.
  • The principal difference between the two embodiments of the invention shown is in the valve stem which necessitates a change in the interior bore of the adapter, which also dictates a different structural relationship for holding the adapter against axial movement by means of the inwardly-directed shoulder of the chassis. [0050]
  • The invention is particularly directed to a simply constructed and reliable faucet handle mechanism made of a minimum number of parts and which hides or masks any fastener which is used to attach the handle mechanism to the valve body and the valve stem. This provides a pleasing exterior appearance for the handle mechanism and one which may not be vandalized as there is no visible means to remove the handle from the valve stem. The screw which is used to fasten the several described members together is completely on the inside of the mechanism. [0051]
  • 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. [0052]
