Abstract

A tool assembly includes an elongated handle and a locking system for attaching a tool head to the handle. The tool head can be a floor care tool or other accessory that can be attached to the handle such that the elongated length of the handle can aid in the use of the tool attached. The locking system includes a keyed locking collar for engaging at least a first portion of the tool head, and a locking cap rotatably positioned on the handle for engaging a second portion of the tool head. The handle can be extendable, such as by telescoping, and can also be overmolded.

First claim

What is claimed is:

1. A universal handle for use with a plurality of tool heads, the handle comprising:
an elongated handle having first and second ends;
a mounting member at the first end of the handle; and
a locking system positioned at or near the second end of the handle, the locking system comprising:
a. a keyed locking collar for engaging at least a first portion of the tool head, wherein said locking collar being external to, independent of, and at least partially surrounding the handle; and
b. a locking cap rotatably positioned on the handle for engaging a second portion of a tool head, wherein said locking cap surrounding at least a portion of both the handle and the keyed locking collar and being rotatable relative to both the handle and the keyed locking collar while being substantially fixed about a longitudinal length of the handle;

wherein said keyed locking collar comprises one or more grooves and said locking cap comprises protrusions aligned with said grooves to allow the locking cap to rotate relative to the keyed locking collar and to keep the locking cap substantially fixed about the longitudinal length of the handle.

2. The universal handle of claim 1 , wherein the locking cap comprises an internal engagement member for attaching to the second portion of the tool head.

3. The universal handle of claim 2 , wherein the internal engagement of the locking cap comprises an internal thread.

4. The universal handle of claim 1 , wherein the keyed locking collar comprising at least one detent for aligning with the first portion of the tool head, said detent used to orient the handle relative to the tool head.

5. The universal handle of claim 4 , wherein said keyed locking collar is affixed to the elongated handle at a location at or near the second end.

6. The universal handle of claim 1 , wherein said locking cap at least partially surrounds a portion of the keyed locking collar in the groove(s) of the keyed locking collar.

7. The universal handle of claim 6 , wherein said locking cap comprising first and second portions attached to another around the keyed locking collar.

8. The universal handle of claim 1 , wherein the elongated handle is overmolded.

9. A tool assembly for use with cleaning, the assembly comprising:
a universal handle comprising an elongated handle having first and second ends, a mounting member at the first end, and a locking system positioned at or near the second end of the handle, the locking system comprising a keyed locking collar for engaging at least a first portion of a tool head, wherein said locking collar being external to, independent of, and at least partially surrounding the handle, and a locking cap rotatably positioned on the handle for engaging a second portion of a tool head, wherein said locking cap surrounding at least a portion of both the handle and the keyed locking collar and being rotatable relative to both the handle and the keyed locking collar while being substantially fixed about a longitudinal length of the handle;
wherein said keyed locking collar comprises one or more grooves and said locking cap comprises protrusions aligned with said grooves to allow the locking cap to rotate relative to the keyed locking collar and to keep the locking cap substantially fixed about the longitudinal length of the handle; and
a tool operatively attached to the universal handle, the tool comprising a head member comprising a body and including first and second connection points for connecting the head member to the universal handle, and at least one engaging member attachment operatively connected to the head member for selectively attaching one of a plurality of engaging members to the head member.

10. The assembly of claim 9 , wherein at least a portion of the universal handle is positioned through the second connection point of the tool and operatively positioned at the first connection point thereof.

11. The assembly of claim 9 , further comprising a tool insert positioned within a substantially hollow portion of the tool body.

12. The assembly of claim 11 , wherein the tool insert comprises:
a. a reservoir;
