Description:
ERGONOMIC POLE FOR AN IMPLEMENT

BACKGROUND OF THE DISCLOSURE

[0001] 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’s use of the pole.

[0002] 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 chader 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.

[0003] 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.

DETAILED DESCRIPTION OF THE DISCLOSURE

[0042] 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’s height.

[0043J 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.

[0044] 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.

[0045] 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).

[0046] 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.

[0047] 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.

[0048] 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 Ai to place the implement 132 (FIG. 8) at the desired orientation to the work surface. The angle Ai 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.

[0049] Referring now to FIGS. 9 - 14, an embodiment is shown of another pole 200 for use with implements, such as cleaning implements. Similar to the pole 100, the pole 200 includes an elongated cylindrical handle or member 202.

In the illustrated embodiment, the coupler 310 has a threaded portion, however, any suitable coupling mechanism may be used. In the illustrated embodiment, the coupler 310 is the same as the coupler 110. In an embodiment, the coupler 310 is removably coupled to the member 302 to allow a coupler with a different attachment means to be used. In the illustrated embodiment, the coupler 310 includes a cylindrical portion sized to be received within the first straight segment 304. The coupler 310 may be secured to the first straight segment 304 by a fastener (not shown). [0060] The second straight segment 306 is coupled to the first straight segment by a first curved segment 316. In the illustrated embodiment the radius and center of the curved segment 316 is sized and positioned such that tire first straight segment and second straight segment extend tangentially from the curved segment 316.

[0061] The second straight segment 306 is coupled to the third straight segment 308 by a second curved segment 318. In the illustrated embodiment the radius and center of the second curved segment 318 is selected such that the first straight segment and second straight segment extend tangentially from the curved segment 316. Coupled to the third straight segment 308 is a grip member 320. In an embodiment, the grip member 320 is the same as grip member 120. The grip member 320 is made from a material that allows the user to comfortably hold the grip member for periods of use. In an embodiment, the grip member 320 may be movable along the length of the third straight segment by the user. In an embodiment, the grip member 320 may be moved further down along the pole 300 onto the second curved member 318 or even the second straight segment 306 if desired by the user. Also coupled to the end of the third straight member 308 is a handle 322. In the illustrated embodiment, the handle 322 is the same as handle 122. The handle 322 includes an opening on one end sized to receive the end of the third straight segment 308. The handle 322 includes a contoured outer surface that is shaped to allow the user to comfortably hold and apply force to the pole 300. The end of the handle 322 is curved to allow a user to comfortably place their palm on the end if desired during use. In an embodiment, the handle 322 may include a hole that extends there through adjacent the end.

[0062] The proportions of the segments 304, 306, 308, 316, 318, 320, 322 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 204 at the desired angle Ai to place the implement 332 (FIG. 22) at tire desired orientation to the work surface.

[0063] As discussed herein, it is desired to provide an ergonomic handle that allows the operator to use the implement, such as to clean a work surface, without having the user bend or hunch-over with their back. In order words, keep the users back straight, or substantially straight during operation. This is accomplished while maintaining the first segment 104, 204, 304 at the desired angle for efficient operation of the implement. Referring now to FIG. 8, FIG. 15, and FIG.22, dimensions for examples of ergonomic poles 100, 200, 300, 400 is shown in accordance with one or more embodiments, where the angle A T is the angle from vertical at which the implement may be efficiently operated:

Table 1

[0064] 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 Ai, 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.

[0065] In one or more other embodiments, dimensions for the ergonomic poles 100, 200, 300, 400 may include:
