Further, handles 20 , 22 allow the end user to easily adjust the stationary/rotational grip for each of the handles without having to significantly change hand position, which improved ergonomics and reduced fatigue.
- Handles 20 , 22 are further configured, due to the integration of both stationary and rotational portions 12 , 14 into a unitary assembly immediately adjacent one another, so that the user can allow their hand to bridge stationary and rotational portions 12 , 14 so that some fingers are on the stationary portion and others are on the rotational portion. In this manner, the user can switch between grasping the stationary portion 12 and the rotational portion 14 by merely adjusting which of their fingers is applying pressure to the handles 20 , 22 .
- scrubbing tasks are intended to define tasks that require the user to apply an additional force along the axis (A) to increase the localized force between tool 18 and the surface being cleaned.
- stationary portion 12 of both handles 20 , 22 provides the user increased control of tool 18 , which can be particularly useful in tight spaces and scrubbing tasks.
- ease with which the user can switch between grasping stationary portion 12 and rotational portion 14 on each of handles 20 , 22 provides increased ease than previously possible.

Rather, it has been determined that length (L2) ofstationary portion 12 ofmiddle handle 22 having enough length to receive one or two fingers (i.e., about 2 inches) provides sufficient area for the user to controltool 18 by preventing rotation when desired. For example, positioning of stationary androtational portions stationary portion 12 and others are on therotational portion 14. In this manner, the user can switch between grasping thestationary portion 12 and grasping therotational portion 14 by merely adjusting which of their fingers is applying pressure to thehandles portions - During assembly,
rotational coupler 30 is inserted into abore 32 ofstationary portion 12.Coupler 30 is fixedly secured torotational portion 14 so as to secureportions coupler 30 can havescrews 34 passed through the coupler and intonuts 36 held byrotational portion 14. - Of course, it is contemplated by the present disclosure for
portions - Finally,
stationary portion 12 is secured topole 16. In the illustrated embodiment,stationary portion 12 includes astationary coupler 38 that receives a rivet or other mechanical fastener (not shown) to secure the stationary portion topole 16 in a manner that prevents rotation about the axis (A) and prevents translational movement along the axis (A). Of course, it is contemplated by the present disclosure forstationary portion 12 to be secured topole 16 in any desired manner that is sufficient to prevent rotation about the axis (A) and prevent translational movement along the axis (A) such as, but not limited to, a press fit, an adhesive connection, a welded connection, and any others. -
Middle handle 22 is described in more detail with reference toFIG. 8 .Middle handle 22 includesstationary portion 12,rotational portion 14, and a fixingcoupler 40.Coupler 40 capturesrotational portion 14 between the coupler andstationary portion 12 so as to allow theportions portions - Additionally,
stationary portion 12 is secured topole 16 in a manner that prevents rotation of the stationary portion about the axis (A) and prevents translational movement of the stationary portion along the axis (A). In the illustrated embodiment,stationary portion 12 includes astationary coupler 38 that receives a rivet or other mechanical fastener (not shown) to securestationary portion 12 topole 16. Of course, it is contemplated by the present disclosure forstationary portion 12 to be secured topole 16 in any desired manner that is sufficient to prevent rotation about the axis (A) and prevent translational movement along the axis (A) such as, but not limited to, a press fit, an adhesive connection, a welded connection, and any others. - Similarly,
coupler 40 receives a rivet or other mechanical fastener (not shown) to secure thecoupler 40 topole 16 in a manner that prevents rotation about the axis (A) and prevents translational movement along the axis (A). Of course, it is contemplated by the present disclosure forcoupler 40 to be secured topole 16 in any desired manner that is sufficient to prevent rotation about the axis (A) and prevent translational movement along the axis (A) such as, but not limited to, a press fit, an adhesive connection, a welded connection, and any others. In this manner,rotational portion 14 is freely rotatably betweencoupler 40 andstationary portion 12 in a desired position onpole 16. - During assembly,
stationary portion 12 includes aregion 42 that is inserted into abore 44 ofrotational portion 14.Coupler 40 andstationary portion 12 are fixedly secured topole 16 so as to securerotational portion 14 between the coupler and the stationary portion. - Advantageously,
stationary portion 12 remains in the preset position onpole 16 without rotation about axis (A) or translation along axis (A), whilerotational portion 14 remains in the preset position onpole 16 without translational movement along axis (A), but in a manner that allows free rotation about axis (A). Moreover,portions tool 18 in a plurality of combinations not previously possible. -
Handles 10 of the present disclosure find use withpole 16 configured as the bent/offset pole andtool 18 that requires a back-and-forth cleaning path such as inFIG. 1 . The back-and-forth cleaning path is shown inFIG. 9 , wheretool 18 is pulled along a surface being cleaned while the leading edge (Le) of thetool 18 is moved back-and-forth. The back-and-forth motion can be efficient for cleaning large areas. The ease of movement oftool 18, or lack thereof, can be magnified in instances where the total surface area of the surface being cleaned/conditioned is large—either by virtue of there being a single large surface or multiple smaller surfaces.Handles 10 of the present disclosure have been found to reduce fatigue by improving the efficiency of motion by increasing the use of larger muscle groups when cleaning is desired when cleaning/conditioning surfaces by providing more flexibility to meet each user's particular method of inducing the back-and-forth cleaning path. - Specifically, it has surprisingly been found by the present disclosure that different users induce the same back-and-forth cleaning path with such bent/offset
poles 16 in very different manners—such that providing handles 20, 22 both with stationary androtational portions rotational portion 14 of bothhandles stationary portion 12 ofmiddle handle 22 to induce the back-and-forth cleaning path while grippingrotational portion 14 ofupper handle 20 so that the upper handle rotates freely. Still other users primarily make use ofstationary portion 12 oftop handle 20 to induce the back-and-forth cleaning path while grippingrotational portion 14 ofmiddle handle 22 so that the middle handle rotates freely. Still other users make primary use ofstationary portions 12 of both top andmiddle handles - Advantageously, handles 20, 22 allow the end user to determine which combination of stationary/
rotational portions -
Handles rotational portions rotational portions stationary portion 12 and therotational portion 14 by merely adjusting which of their fingers is applying pressure to thehandles - Moreover, it has been found by the present disclosure that use of only handles that freely rotate creates issues when utilizing
tool 18 in cleaning tasks that do not require the back-and-forth motion—such as in tight spaces (e.g., around table legs, chairs, and the like) and/or during scrubbing tasks. As used herein, scrubbing tasks are intended to define tasks that require the user to apply an additional force along the axis (A) to increase the localized force betweentool 18 and the surface being cleaned. - Here, use of
stationary portion 12 of bothhandles tool 18, which can be particularly useful in tight spaces and scrubbing tasks. Again, the ease with which the user can switch between graspingstationary portion 12 androtational portion 14 on each ofhandles - Although various attributes of assembly are described herein with respect to different embodiments, it is contemplated by the present disclosure for the assembly to include any of the attributes described herein in any desired combination.
- It should also be noted that the terms “first”, “second”, “third”, “upper”, “lower”, “front”, “back”, and the like may be used herein to modify various elements. These modifiers do not imply a spatial, sequential, or hierarchical order to the modified elements unless specifically stated.
- While the present disclosure has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the scope thereof. Therefore, it is intended that the present disclosure not be limited to the particular embodiment(s) disclosed as the best mode contemplated.
