Title: Ergonomic pole for an implement

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application Ser. No. 62/811,822, filed Feb. 28, 2019, the entire disclosure of which is incorporated herein by reference. 
    
    
     BACKGROUND 
     The subject matter disclosed herein relates to a handle or pole for use with a cleaning implement such as a floor squeegee, broom, brush or mop for example, and in particular to an ergonomic shaped pole that facilitates the user&#39;s use of the pole. 
     Handles for cleaning implements that require continuous forward and downward forces, such as brooms or squeegees for example, typically have straight poles. Due to a need to apply a downward and forward force simultaneously, the user typically puts a palm of one hand on the end of the pole and their other hand part partially down the pole. In order to keep the cleaning implement at a desired angle for efficient operation (e.g. squeegees will chatter if not held at a desired angle), and because the poles are straight, the user will assume a bent over position while using the cleaning implement. This is obviously less than desired because it could lead to faster fatigue. 
     Accordingly while existing poles are suitable for their intended purposes the need for improvement remains, particularly in providing an ergonomic shape pole having the features described herein.

     The detailed description explains embodiments of the disclosure, together with advantages and features, by way of example with reference to the drawings. 
     DETAILED DESCRIPTION 
     Embodiments of the present disclosure provide for an ergonomic pole that is used with implements, such as cleaning implements, squeegees, brooms, brushes, mops, plows, or poles, which allows the user to provide forces in the desired direction(s)/vectors without substantially bending their back during normal operation. Embodiments of the present disclosure further provide for an ergonomic pole for use with implements that has an adjustable length to accommodate a user&#39;s height. 
     Ergonomic poles have been proposed for use with tools, such as snow shovels for example. These poles allow a user to lift material (e.g. snow or dirt) without having the user bending as far down, allowing them to more efficiently use their legs in a lifting motion to reduce stain on their back. Further, the shape of the pole allows the user to place on of their hands close to the shovel end for stability. These lifting ergonomic poles are unsuitable for use with other types of cleaning implements, such as brooms or squeegees. For these types of cleaning implements, the user is not lifting material, but rather is placing a downward force and a forward force simultaneously while in use. Unlike a shovel which has intermittent usage, the forces on a broom or squeegee are more continuous. Further, some cleaning implements such as squeegees are held within a predetermined angle during use for efficient operation. When a squeegee is held outside of this angular range, the squeegee blade may chatter or bounce, causing portions of the liquids being removed to be left behind or have an increased force required to push the squeegee forward to clean/move the material/debris. 
     Referring now to  FIGS. 1-8 , an embodiment is shown of an ergonomic pole  100  for use with implements, such as cleaning implements. The pole  100  includes an elongated cylindrical handle or member  102 . In the illustrated embodiment, the member  102  is a thin walled tubular member made from a metallic material, such as but not limited to: aluminum, steel, metallic alloys, fiberglass, carbon fiber and epoxy, or wood or a combination of the foregoing with or without grips, texture or surface treatments for example. It should be appreciated that other materials, such as a plastic/polymer material or a combination or plastic and metal for example. It should further be appreciated that while embodiments herein may describe the member  102  as being tubular or hollow, this is for example reasons and the claims should not be so limited. In other embodiments, the member  102  may be made from a solid material. It is also contemplated that the cross section can be other than cylindrical, such as oval, trilobal, etc. The pole surface can also be textured or have grips attached such as with adhesive. 
     In the illustrated embodiment, the member  102  is comprised of a plurality of straight segments connected by curved segments. The straight segments are arranged to facilitate placing the implement at the desired orientation (angle relative to the surface it is placed) while allowing the user to push on the pole  100  and keep their back straight or substantial straight (e.g. not bent or hunched over) while making it easy (improving) to get the correct pushing (forward) and cleaning (downward) forces. The member  102  includes a first straight segment  104 , a second straight segment  106 , and a third straight segment  108 . Coupled to the first straight segment  104  is a coupler  110 . In an embodiment, the coupler  110  is configured to engage a corresponding member on the implement and secure the implement to the pole  100 . In the illustrated embodiment, the coupler  110  has a threaded portion  112  and a cone portion  111  ( FIG. 7C ), however, any suitable coupling mechanism may be used. In an embodiment, the coupler  110  is removably coupled to the member  102  to allow a coupler with a different attachment means to be used. In the illustrated embodiment, the coupler  110  includes a cylindrical portion  114  sized to be received within the first straight segment  104 . The coupler  110  may be secured to the first straight segment  104  by a fastener (not shown). 
     The second straight segment  106  is coupled to the first straight segment by a first curved segment  116 . In the illustrated embodiment the radius and center of the curved segment  116  is sized and positioned such that the first straight segment and second straight segment extend tangentially from the curved segment  116 . 
     The second straight segment  106  is coupled to the third straight segment  108  by a second curved segment  118 . In the illustrated embodiment the radius and center of the second curved segment  118  is selected such that the first straight segment and second straight segment extend tangentially from the curved segment  116 . Coupled to the third straight segment  108  is a grip member  120 . The grip member  120  is made from a material that allows the user to comfortably hold the grip member for periods of use. The grip member  120  may be made from a material such as foam, thermoplastic elastomer (TPE), plastic, or the like. The grip could be smooth or have finger grips or contoured outer surface that is shaped to allow the user to comfortably hold and apply force to the pole. In an embodiment, the grip member  120  may be movable along the length of the third straight segment by the user. In an embodiment, the grip member  120  may be moved further down along the pole  100  onto the second curved member  118  or even the second straight segment  106  if desired by the user. Also coupled to the end of the third straight member  108  is a handle  122 . The handle  122  includes an opening  124  on one end sized to receive the end of the third straight segment  108 . The handle  122  includes a contoured outer surface  126  that is shaped to allow the user to comfortably hold and apply force to the pole  100 . The end  128  of the handle  122  is curved to allow a user to comfortably place their palm on the end if desired during use. In an embodiment, the handle  122  may include a hole  130  that extends there through adjacent the end  128 . 
     The proportions of the segments  104 ,  106 ,  108 ,  116 ,  118 ,  120 ,  122  will be discussed herein with respect to Table 1. The sizes and proportions are selected to provide a desired height H and length L while maintaining the first segment  104  at the desired angle A 1  to place the implement  132  ( FIG. 8 ) at the desired orientation to the work surface. The angle A 1  is sometimes referred to as the functional angle as it is the angle of the first segment that places the implement at a desired orientation/angle.

     The lengths of the straight segments D 1 , D 2 , D 3  are measured from the intersection of the centerlines (datum point) of the respective straight segments. The height H of the end of the handle is measured to the intersection of the centerline of the third straight segment and the end surface of the handle. The length of the pole is measured from the intersection of the centerline of the first straight segment and the bottom of the coupler to the intersection of the centerline of the third straight segment and the end surface of the handle. It has been found that that when the end of the pole  100 ,  200 ,  300  is placed at the height H, length L and angle A 1 , the implement operates at the desired efficiency. It should be appreciated that the pole selected by the user may depend on the height of the user. A user who is taller may prefer pole  100  or pole  200 , which have a higher operating height, while a user who is shorter may prefer pole  300  that has a lower operating height.
