Definitions
- Mop holder for a mop system mop system, mop handle for a mop system and use of the mop system
- the invention relates to a mop frame and a mop system comprising a mop frame and a mop handle.
- the invention also includes a mop handle for a mop system.
- the use of the mop system for cleaning floors, walls and/or ceilings, in particular in preferably sterile clean rooms, is provided.
- Mop systems are used for cleaning floors or other surfaces in clean rooms.
- Working in clean rooms is associated with special hygiene requirements. This applies to the work equipment and processes that can be used in clean rooms. It is of primary importance to prevent the introduction of contaminants, such as particles and/or germs, into the cleanroom, as well as any cross-contamination of clean objects by contamination from other objects.
- Disinfectants include, for example, diamines, isopropanol, ethanol, active chlorine, and hydrogen peroxide.
- Detergents include, for example, alkaline detergents such as sodium hydroxide and/or acidic detergents.
- An example of a solvent is acetone.
- a cleaning device for clean rooms in the form of a mop system which comprises a shaft section, a closure element and a holder for a mop cover, is described in DE 20 2013 011946 U1, for example.
- An object of the present invention is now to overcome the disadvantages of the prior art and in particular to provide a device, a kit-of-parts and a method of use which is particularly easy, in particular with as few individual handling movements as possible, and / or applying a is to be used by cleaning staff with as little effort as possible.

- the proportion of the aramid and/or carbon fiber reinforced plastic is determined in particular in relation to the surface of the mop holder, preferably that side of the mop holder which is directed towards the floor.
- the proportion of fiber-reinforced plastic in the mop holder does not take into account a connecting piece for connecting the mop holder and mop handle to one another, which is realized in particular by an articulated connection. Because the mop holder is made of aramid- and/or carbon-fiber-reinforced plastic material to save weight, a particularly effective workload reduction for the cleaning staff can be created.

- the mop holder has a rectangular basic shape.
- the mop frame has a length in the range of 35 to 55 cm, in particular in the range of 40 cm to 50 cm, preferably 40 cm to 50 cm, and a width in the range of 8 or 10 cm to 20 cm, in particular in the range of 12 up to 17 cm.
- the mop holder can be used in particular in combination with the mop handle described below.
- the mop holder can be implemented as a flat mop holder with a first mop holding wing and a second mop holding wing.

- At least one of the two mop holding wings is movable relative to the other mop holding wing.
- the second mop holding wing can be pivoted relative to the first mop holding wing and a connector attached or attachable to the first mop holding wing.

- At least one of the holding wings in particular both of the holding wings, can have a longitudinal rib, in particular curved convexly towards the upper side.
- the at least one longitudinal rib extends from a flat section to the top.
- flat sections of the retaining wing can be provided on both sides in the transverse direction.
