Definitions

  • the invention relates to a mop holder, a connecting piece and a kit-of-parts formed with the aforementioned components.
  • the use of the mop holder, connecting piece or kit-of-parts is intended for cleaning, in particular of floors, walls and/or ceilings, in sterile clean rooms.
  • Mop systems are used to clean floors or other surfaces in clean rooms.
  • Working in clean rooms involves special hygiene requirements. This affects the work equipment and processes that can be used in clean rooms. It is of primary importance to prevent the introduction of contamination, such as particles and/or germs, into the clean room, as well as any cross-contamination of clean objects due to contamination from other objects.
  • mop systems and other work equipment that are brought into clean rooms must be decontaminable and disinfectable, and if necessary even sterilizable, for example by autoclaving at 121 °C for up to 25 minutes or at 134 °C for up to to 6 minutes.
  • the mop systems must also be resistant to cleaning agents, disinfectants and/or solvents.
  • Disinfectants include, for example, diamines, isopropanol, ethanol, active chlorine, hydrogen peroxide.
  • Cleaning agents include, for example, alkaline cleaning agents, such as sodium hydroxide, and/or acidic cleaning agents.
  • a solvent is, for example, acetone.
  • the mop cover When cleaning clean rooms, the mop cover usually has to be replaced after each cleaning process, which means that a large number of mop covers are often required to clean a room.
  • the mop covers are usually changed after approx. 15-20 m 2 .
  • Manually touching the mop by cleaning staff is disadvantageous as cross-contamination can occur. In this case, contamination can be transferred from a used mop pad to a user and from a user to a fresh mop pad or other items in the clean room. This can lead to undesirable contamination of the cleanroom.
  • To avoid cross-contamination when using mop systems fresh mop covers are picked up and used mop covers are thrown away without hand contact. This also prevents cleaning staff from having to bend down when picking up and/or throwing off a mop cover.
  • a cleaning device for clean rooms in the form of a mop system that includes a shaft section, a closure element and a holder for a mop cover is described, for example, in DE 20 2013 011946 Ui.

  • the threaded sleeve can be rotated towards the mop holder to pretension the spiral spring in order to limit or prevent mobility of the mop holder relative to the mop handle about one axis.
  • the position of the mop holder relative to the mop handle around the further axis is unaffected by the force applicator.
  • the proposed mop system has proven to be rather disadvantageous and unergonomic for use, for example, in clean rooms in which not only floor surfaces but also wall surfaces and ceiling surfaces have to be cleaned.
  • the adjusting sleeve After the adjusting sleeve has been tightened to tension the spiral spring for treating the wall or ceiling surfaces, it must be loosened again for the floor surfaces, otherwise the restoring force will be perceived by the cleaning staff as disruptive and tiring. It is not readily apparent to the cleaning staff whether the adjusting sleeve is in a loosened, tightened or intermediate state.
  • the adjustment sleeve also requires a number of additional steps to adjust the force applicator.
