## Title
Handle for a floor cleaning implement

## Abstract

A handle for an implement for cleaning a surface, such as a floor, includes an elongated pole, an end cap and a hang cap. The elongated pole has a top end and a bottom end. The bottom end of the elongated pole is adapted to be coupled to a cleaning head on the implement. The end cap is fixedly mounted over the top end of the pole and the hang cap is movably mounted over the end cap. The end cap and hang cap are constructed so that when the hang cap is mounted in place on the end cap, the hang cap can rotate relative to the end cap but cannot move up or down relative to the end cap. This construction includes a pair of lateral grooves on the outer surface of the end cap and a pair of lateral ribs on the inner surface of the hang cap which are in registration with the lateral grooves on the end cap when the hang cap is mounted over the end cap. The hang cap has a hole for removably mounting the implement on a hook attached to a wall. In one version of the handle, the hang cap is shaped straight while in another version of the implement the hang cap is angled (i.e. bent). Since the hang cap can be rotated relative to the end cap and the end cap is fixed relative to the elongated pole, the pole can easily be rotated relative to the hang cap so that cleaning the head is at the proper orientation against the wall on which the hook is mounted.

## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to floor cleaning implements and more particularly to handles for floor cleaning implements.
Floor cleaning implements are well known and widely used to clean hard flooring surfaces such as ceramic tile, hardwood, laminate, linoleum and marble floors. Examples of floor cleaning implements are mops, dusters and brooms.
Floor cleaning implements usually include a cleaning head and a cleaning element. The cleaning element is either fixedly mounted on the cleaning head or removably mounted on the cleaning head. Examples of cleaning elements are sponges, brushes and sheets of fabric material.
Floor cleaning implements also usually include a handle. The handle usually comprises an elongated pole about 31⁄2 to 41⁄2 feet in length and having a top end and a bottom end. The bottom end of the pole is attached, either fixedly or pivotally, to the cleaning head. The handle also often includes a hang cap which is attached to the top end of the pole. The purpose of the hang cap is to enable a person to hang the cleaning implement on a hook which may be on a wall or other surface rather have the cleaning implement rest on a floor.
Hang caps are shaped either straight (i.e. their longitudinal axis is straight) or angled (i.e. their longitudinal axis is bent at an angle in the vicinity of around 130 to 150 degrees). Some straight hang caps are fixedly mounted onto the top end of the pole while other straight hang caps are rotatably mounted onto the top end of the pole so that the pole can necessary, relative to the hang cap in order to position the cleaning head at the bottom of the pole at the proper orientation with the wall on which the hook is attached.

SUMMARY OF THE INVENTION
A handle for a floor cleaning implement constructed according to this invention comprises an elongated pole, a hang cap and an end cap, the elongated pole having a top end and a bottom end, the bottom end of the pole being adapted to be coupled to a cleaning head on the floor cleaning implement, the end cap being fixedly mounted over the top end of the pole and the hang cap being movably mounted over the end cap, the end cap and the hang cap being constructed so that when the hang cap is mounted in place on the end cap, the hang cap can move rotationally relative to the end cap but not up or down relative to the end cap. The hang cap can be either straight or angled. Since the hang cap can rotate on the end cap and the end cap is fixed relative to the pole, the pole can be rotated relative to the hang cap, if necessary, to orient the cleaning head properly when the cleaning implement is mounted on a hook attached to a wall or other surface.
The handle may be assembled as follows. First, the end cap is press fit down over the top end of the pole to fixedly mount the end cap on the pole. Then the hang cap is pushed down over the end cap until it snap fits in place.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, and first to FIG. 1, there is shown a floor cleaning implement which includes a handle constructed according to this invention, the floor cleaning implement being identified by reference numeral 11.
Floor cleaning implement 11 includes a cleaning head 13, a cleaning element 15, such as a sheet of fabric material, removably mounted on cleaning head 13 and a handle 17 pivotally mounted on cleaning head 13. Cleaning head 13 includes a handle coupling member 19 which is pivotally mounted on a base 21.
Handle 17, which is shown in detail in FIGS. 3 and 7 includes an elongated tubular pole 23 having a top end 25 and a bottom end 27. Bottom end 27 of pole 23 is fixedly secured by any suitable means such as glue or fasteners, not shown, to handle coupling member 19.
Handle 17 also includes an end cap 29 which is fixedly mounted over top end 25 of pole 23 and a hang cap 31 which is movably mounted over end cap 29. More specifically, end cap 29 and pole 23 are sized relative to each other so that end cap 29 can be press fit over top end 25 of pole 23. In addition, end cap and 29 and hang cap 31 are sized and shaped relative to each other as will hereinafter be explained and shown so that hang cap 31 can be snap-fit over end cap 29 in a manner such that hand cap can 31 can rotate as shown in FIG. 1 in direction A about longitudinal axis B relative to end cap 29 but cannot move up or down relative to end cap 29.
As can be seen in the drawings, and in particular FIGS. 2, 3, 6 and 7 end cap 29 is an elongated tubular member having an open bottom 33, a closed top 35 and a sidewall 37 having an outer surface 39 that is generally cylindrically shaped. The inside cross-sectional diameter of end cap 29 is very slightly larger than the outside cross-sectional diameter of pole 23 so that end cap 29 can be pres-fit onto pole 23. A pair of spaced apart lateral grooves 41 and 43 are formed on outer surface 39 of end cap 29.
Hang cap 31 is a generally oval shaped member whose longitudinal axis C is straight. Hang cap 31 includes a hole 45 for use in hanging hang cap 31 on a hook or other similar means, an open bottom 47 and an axial bore 49 extending inward from open bottom 47 and which is generally circular in cross-section. Axial bore 49 includes an outer portion 61 and an inner portion 53. Outer portion 51 of bore 49 has a cross-sectional diameter slightly greater than the outside cross-sectional diameter of end cap 29. Inner portion 53 of bore 49 has a cross-sectional diameter less than the outside cross-sectional diameter of end cap 29.
As can be seen, movement by end cap 29 in an upward direction in bore 51 is limited in that end cap 29 can be pushed up in bore 49 only to the top 54 of bore 51. Thus, top 54 of bore 51 serves as a stop to limit upward movement of end cap 29 in bore 31.
A pair of spaced apart lateral ribs 55 and 57 are provided on the surface 59 outer portion 49 of bore 51. Ribs 55 and 57 are sized, positioned and spaced on surface 59 so as to be in registration with grooves 41 and 43, respectively, on hang cap 29 when hang cap 29 is pushed up into bore 49 to the inner end of outer portion 51. As a result, because ribs 55 and 57 are in grooves 41 and 43, respectively, hang cap can rotate laterally in the direction shown by arrow A in FIG. 1 relative to end cap 29 (and pole 23) but cannot move either up or down relative to end cap 29.
End cap 29 is a single piece and may be made of a rigid plastic such as polypropylene. Hang cap 31 is a single piece that has an over-molding added to it. The main portion 61 may be a rigid plastic such as polypropylene while the over-molding portion 63 may be a plastic material such as TPP. The over molding portion 63 is for gripping purposes as well as appearance.
Handle 17 may be assembled in the following manner. First, end cap 29 is press-fit onto top end 25 of pole 23. Then, hang cap 31 is pushed down over end cap 21 until it snap-fits in place (i.e. when ribs 55 and 57 align with grooves 41 and 43). Then, handle 17 is attached to cleaning head 13. Alternatively, handle 17 may be attached to cleaning head 13 before end cap 29 and hang cap 31 are mounted onto it.
Referring now to FIGS. 8 and 9, there is shown another embodiment of a handle according to this invention, the handle being identified by reference numeral 71.
Handle 71 includes a pole 73, identical to pole 23, an end cap 75 fixedly mounted on top end 77 of pole 73 and which is identical to end cap 29 and a hang cap 79 which is movably mounted on end cap 75 such that it can rotate relative to end cap 75 but cannot move either up or down relative to end cap 75. Hang cap 79 has a longitudinal axis D that is angled (i.e. bent). Except for the fact that its longitudinal axis D is bent, hang cap 79 is identical to hang cap 31.
Handle 71 is assembled in the same manner as handle 17.
Although the invention has been described with regard to a handle for a floor cleaning implement it should be understood that the handle could be used, if desired with other types of implements such as garden tools or carpet cleaning tool.
The embodiments shown in the present invention are intended to be merely exemplary and those skilled in the art shall be able to make numerous variations and modifications to them without departing from the spirit of the present invention. All such variations and modifications are intended to be within the scope of the present invention as defined in the appended claims.
