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.

  • 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.
