Abstract

A decorative handle which is attachable to a rotatable stem and has a decorative insert held therein is disclosed. In one version, the insert member is retained by a retainer assembly which engages the decorative insert. The retainer assembly holds the insert against a narrowed open top of the handle from below. A collar member which is threaded onto the handle from the bottom provides the force to hold the retainer in place. A decorative handle is provided which can be assembled and disassembled without tools, yet is highly aesthetic as the engagement of the component parts is obstructed from view as is a portion of the attachment to the valve assembly. Further, the inserts can be readily changed when the room where the handle is placed is remodeled.

Claims

1. A handle assembly having a decorative insert member comprising:

a handle defining a cavity that converges along at least a part of it to define a stem attachment end and a decorative end;

a retainer assembly adapted to engage said insert member, said retainer assembly and said handle constructed and arranged to restrict movement of said retainer assembly with said insert member through said decorative end;

a collar member having a threaded portion for engagement with a threaded portion on said handle;

said handle, said retainer assembly and said collar member being constructed and arranged to exert a driving force on said retainer assembly in the direction of said decorative end when said threaded portions on said collar member and said handle engage; and

means to secure said handle assembly to a rotatable stem.

2. The handle assembly as defined in claim 1 wherein said threaded portion of said collar member is defined by an external threaded portion and said threaded portion of said handle is defined by internal threads disposed in side walls of said handle.

3. The handle assembly as defined in claim 1 wherein said threaded portion of said collar member is defined by an internal threaded portion.

4. The handle assembly as defined in claim 3 wherein said retainer assembly comprises a cup with strap members extending therefrom and an end portion of an adaptor attachable to said stem, the end portion of the adaptor defining portions for receiving said strap members to connect the cup to the adaptor.

5. The handle assembly as defined in claim 1 wherein said retainer assembly and said collar member are rotatably mounted to each other.

8. The assembly of claim 1 further comprising:

a flexible cup which can surround portions of the stem end and the sides of the end cap to frictionally retain the cap in the cup;

said cup also having a projection therefrom extending towards said stem end; and

an escutcheon insertable in and connectable to the knob bore stem end having an end abutment surface;

whereby said abutment surface acting against said projection can increase the frictionable engagement of said cap and cup.

9. The assembly of claim 1, wherein the end cap is assembled to the assembly by passing it through the knob bore from the stem end to a narrowed decorative end of the bore.

10. The assembly of claim 9, wherein the attachment mean comprises:

an escutcheon insertable in the knob stem end having threads formed on to radial periphery and an end support surface; and

inner threads on the inside of the housing side surfaces;

whereby a meshing of the inner and radial threads causes the support surface to hold a support wall of the adaptor in the housing.

11. The assembly of claim 10, wherein the support wall is sandwiched between the cap and support surface.

12. The assembly of claim 10, wherein a flexible cup surrounds portions of the stem end and sides of the cap when it is assembled in the assembly, and is sandwiched between the cap and support wall when so assembled.

6. In a handle assembly attachable to a rotatable stem, of the type having a handle knob with outer side surfaces, an internal through bore extending from a stem end to a decorative end, and an outer removable decorative end cap positionable at the decorative end, the improvement comprising:

adaptor means connectable to the stem and knob interior so that all three can rotate together; and

attachment means removably connectable to the inside of the housing without projecting through said side surfaces of the knob to cause the cap to be held in a portion of the bore adjacent to said decorative end with a decorative end of the cap visible on the knob exterior;

whereby when the assembly is assembled the decorative end cap cannot readily be disassembled from the knob without first adjusting said attachment means from the stem end of the knob.

7. The assembly of claim 6, wherein the adaptor means is integral with the knob.

13. A handle assembly having a decorative insert member, comprising:

a handle defining a cavity that converges along at least a part of it to define a stem attachment end and a decorative end;

a panel portion extending laterally across the cavity having at least one opening therethrough;

a holder member adapted to engage said insert member, said holder member and said handle constructed and arranged to restrict movement of said holder member with said insert member through said decorative end, said holder member having a leg member for placement through said panel opening in said panel portion;

a collar member having a threaded portion for engagement with a threaded portion extending from said panel portion of said handle, said collar member and said leg member constructed and arranged to exert a driving force on said holder member when said collar member contacts said leg and moves said holder member in the direction of said smaller decorative end when said threaded portions on said collar member and said handle engage; and

means to secure said handle to a rotatable stem.

14. The handle assembly as defined in claim 13 wherein said holder member includes a cup portion for holding said insert member.

15. The handle assembly as defined in claim 14 wherein said panel portion has a plurality of said openings extending therethrough and said holder member has a plurality of leg members for placement through said openings.
