Definitions
- the subject matter disclosed herein relates to a tool for cleaning surfaces such as a floor, and in particular to a cleaning tool such as a broom, mop, brush, or squeegee that has an ergonomic pole and modular element(s) allowing the cleaning tool to be configured during manufacturing or by an end user.
- a cleaning tool such as a broom, mop, brush, or squeegee that has an ergonomic pole and modular element(s) allowing the cleaning tool to be configured during manufacturing or by an end user.
- Cleaning tools and implements such as brooms and brushes, typically include bristles that are used to sweep or gather up debris from the floor. These brooms and brushes are fixed in size and configuration, resulting in dedicated manufacturing lines and increased inventory. Further, it has been found that different types of bristles are suited for cleaning different types of debris. Existing brooms are limited to two different types of bristles. Thus, a user may have to have several different types of brooms depending on the type of environment being cleaned.
- the poles for cleaning tools can require continuous forward and downward forces, typically having 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.
- US 2020 0 187 744 A1 deals with a pole having segments being bent relative to each other. DE 20 2019 102 028 U1 and US 2,753,579 show further examples of brooms having a bent pole.

- the bracket 130 includes a hole 136 that is sized to receive the pole 102.
- the hole 136 is aligned coaxial with the hole 128 and one of the holes 122, 124.
- Ends of the arms 132, 134 may be coupled to the center head member 108 and/or the end modules 110, 112 by a fastener 138, such as screws that extend through the arms 132, 134, center head member 108 and end modules 110, 112 to couple all of the components together.
- the center head member 108 includes a plurality of rows of bristles 188.
- the bristles 188 may be arranged on an angle relative to an axis or first centerline 190 ( FIGS. 4 , 8B ) and/or a second centerline 192 ( FIGS. 4 , 8C ).
- the first centerline 190 defines a plane that extends through the pole 102 and the head member assembly 106 (e.g., substantially perpendicular to a surface being cleaned).
- the second center line 192 defines a plane that extends through the middle of the center head member 108 (e.g., substantially perpendicular to the surface being cleaned and perpendicular to the first plane passing through the first centerline 190, the first plane extending into/out-of the page in the view of FIG. 4 ).
- one or more of the rows of bristles 188 may have separate groups of bristles that are coupled on one end to the body 140.

As discussed herein, this provides advantages in facilitating the cleaning of corners, such as the base of a wall for example.
- 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 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/or a forward force simultaneously while in use.
- cleaning implements such as brooms or squeegees.
- 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.
- the member 502 may be tubular or hollow, this is for example reasons and the claims should not be so limited.
- the member 502 may be made from a solid material. It is also contemplated that the cross section can be other than cylindrical, such as oval, trilobal, squared, etc.
- the exterior surface of the member 502 can also be textured and/or have grips attached, such as with adhesive and/or fastener.
- the coupler 510 is configured to engage a corresponding member on the implement and secure the implement to the pole 500 (e.g., bracket 116).
- the coupler 510 has a threaded portion 512 and a cone portion 511 ( FIG. 28C ), however, any suitable coupling mechanism may be used.
- the coupler 510 is removably coupled to the member 502 to allow a coupler with a different attachment means to be used.
- the coupler 510 includes a cylindrical portion 514 sized to be received within the first straight segment 504. The coupler 510 may be secured to the first straight segment 504 by a fastener (not shown), detent pin, snap-fit, or the like.
- the second straight segment 506 is coupled to the first straight segment 504 by a first curved segment 516.

- Cleaning Implements For Floors, Carpets, Furniture, Walls, And The Like (AREA)
Description
- This application relates to a tool for cleaning a surface.
- The subject matter disclosed herein relates to a tool for cleaning surfaces such as a floor, and in particular to a cleaning tool such as a broom, mop, brush, or squeegee that has an ergonomic pole and modular element(s) allowing the cleaning tool to be configured during manufacturing or by an end user.
- Cleaning tools and implements, such as brooms and brushes, typically include bristles that are used to sweep or gather up debris from the floor. These brooms and brushes are fixed in size and configuration, resulting in dedicated manufacturing lines and increased inventory. Further, it has been found that different types of bristles are suited for cleaning different types of debris. Existing brooms are limited to two different types of bristles. Thus, a user may have to have several different types of brooms depending on the type of environment being cleaned.
- Additionally, in operation and use, the poles for cleaning tools can require continuous forward and downward forces, typically having 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.

Such ergonomic poles may be used with implements, such as cleaning implements, squeegees, brooms, brushes, mops, plows, or poles, which allow a user to provide forces in desired direction(s)/vector(s) 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.
- 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 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/or 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.
