Definitions

  • the invention relates to a floor cleaning machine with a housing which carries on the top a drive unit having an electric motor and on the inside a cleaning and / or polishing disc which is rotatably mounted about an essentially vertical axis and is spring-loaded with respect to its horizontal normal position and is slightly adjustable and which is connected to a pivotably mounted guide rod and a swivel castor chassis.
  • Such a floor cleaning machine is known from DE-A-3638666.
  • a castor is mounted on the underside of a rocker on the underside of the housing in a spring-supported manner and is connected to the housing. This ensures that the cleaning and / or polishing disc no longer has to absorb the total weight of the floor cleaning machine.
  • the roller trolley supports part of the machine weight on the floor. Compared to machines in which the machine weight is supported on the floor only by the cleaning and / or polishing disk, in this known machine the proportion of the weight components pressing the working surface of the disk onto the floor can be kept substantially lower, so that the cleaning and / or polishing disc can be driven at a higher speed and / or the total weight of the Machine can be increased.
  • Standard motors can then be used instead of weight-optimized special motors.
  • this known floor cleaning machine it is also possible to load or relieve the swiveling spring-supported roller carriage by slightly lifting or lowering the guide rod relative to the normal position and thereby releasing corresponding areas of the cleaning and / or polishing disc more strongly onto the floor to press.
  • the front or rear circumferential area of the cleaning and / or polishing disk in the working direction can be pressed more strongly onto the floor. This results in a transverse force acting transversely to the working direction, which leads to the desired oscillating movements of the floor cleaning machine, so that work surfaces can be worked comfortably without the operator having to exert additional force for transverse movement of the machine which are larger than the diameter of the cleaning and / or polishing disc.
  • a disadvantage of this known floor cleaning machine is that a not inconsiderable proportion of the machine weight is always transferred to the floor via the cleaning and / or polishing disk. This leads to the fact that the previously known floor cleaning machine can undesirably break out laterally when starting up. The operating personnel can only counteract this process with effort. In the previously known floor cleaning machine, it is not possible to distribute the machine weight to the roller carriage and the cleaning and / or polishing disc in such a way that the entire surface of the cleaning and / or polishing disc is flat or almost completely depressurized lies on the floor to be cleaned.
  • the object of the invention is to improve a generic floor cleaning machine in such a way that the machine weight is almost exclusively supported on the floor by the undercarriage, but the cleaning and / or polishing disk continues to be focused on the floor in certain areas by pivoting the guide rod can be pressed on.
  • this object is achieved according to the invention in that the swivel castor chassis supports the housing in an equilibrium-stable manner on the floor and in the housing a support plate carrying the drive unit, the cleaning and / or polishing disc and the guide rod by one mounted on the housing and on the plate, horizontal pivot axis is pivotally spring-supported.
  • the support plate provided with the complete drive unit and the cleaning and / or polishing disc and the guide rod is designed so that it can be rocked or swiveled without the housing carrying out the desired rocking or swiveling movement.
  • the entire weight of the machine is supported on the floor by the housing and the swivel roller chassis.
  • the cleaning machine is in its initial or ready position in a stable equilibrium and the cleaning and / or polishing disk lies flat or almost flat with the entire surface on the floor in a pressure-free or approximately pressure-free manner. There is no longer any danger that the floor cleaning machine will break out when the cleaning and / or polishing disk starts up.
  • the floor cleaning machine can be easily pushed back and forth.
  • the resiliently supported mounting of the carrier plate with drive unit and cleaning and / or polishing disc enables it to be tilted or Swiveling in the chassis formed by the housing and the swivel castor chassis by slightly raising or lowering the guide rod.
  • the front or rear circumferential area of the disk in the direction of movement of the floor cleaning machine can be pressed onto the floor to a greater extent, so that a back and forth operation as described above is possible.
  • Due to the formation of a swivel roller chassis the rollers or wheels set themselves crosswise when the rotating cleaning and / or polishing disc is pressed in regions, due to the transverse force generated thereby, and enable the transverse force to be converted into the desired pendulum movement.
  • the total weight of the floor cleaning machine can theoretically be increased to such an extent that the operating personnel are just able to move it.
  • the pressure preload of the compression springs means that the cleaning and / or polishing disc only ever rests on the floor with a slight pressure.
  • An advantageous embodiment of the invention that is technically simple to implement is characterized in that axially opposite one slide block arranged on the support plate and one shaft block arranged on the housing are each formed with a pivot axis connecting them and offset in the direction of the guide rod between the support plate and the housing, also axially opposite each other, a compression spring is arranged.
  • the carrier plate is securely mounted in the housing and can be pivoted against the pressure force of the compression springs using the lever arm of the guide rod without great effort.
  • the pressure preload of the compression springs is expediently set here in such a way that the carrier plate is held in the rest position in an at least approximately horizontal position, as is also provided by the invention.
  • a further advantageous embodiment of the invention consists in that the pressure preload of the compression springs is adjustable.
  • the invention provides in a further embodiment that the swivel castor undercarriage has at least two, preferably three, swivel has rollers, of which at least one swivel roller is height-adjustable. This makes it possible to vary the contact pressure of the cleaning and / or polishing disc on the floor and to adapt the floor cleaning machine to cleaning and / or polishing discs of different disc thickness.
  • a dust ring with bristle trimmings on the bottom is arranged to be height-adjustable. With the help of the dust ring it is prevented that the fan or blower effect generated by the high speed of the cleaning and / or polishing disc does not lead to dust being whirled up. In addition, the network connection cable is prevented from being run over because the bristle covering pushes it aside.
  • the invention provides that the floor cleaning machine has a warning lamp which is switched in a current- and / or power-dependent manner by means of a relay and which lights up when the engine is subjected to excessive stress.
  • the warning lamp lights up the operating personnel are informed that the floor cleaning machine is no longer working in the optimum performance range.

Abstract

Une machine (111) à nettoyer des planchers comprend un boîtier (12) qui porte sur sa partie supérieure une unité d'entraînement (10) pourvue d'un moteur électrique. Le boîtier (12) contient un disque à polir et/ou à nettoyer (61) monté rotatif autour d'un axe (9) sensiblement vertical qui est monté sur des ressorts de manière à pouvoir être légèrement ajusté par rapport à sa position horizontale normale. Le boîtier est relié à une tige de guidage (20) montée pivotante et à un mécanisme de roulement à roulettes pivotantes. Une telle machine doit être améliorée de sorte que le poids de la machine soit presque exclusivement porté sur le sol par le mécanisme de roulement à roulettes pivotantes, et que le disque à polir et/ou à nettoyer puisse être appliqué avec plus de force sur des zones bien circonscrites du plancher, par pivotement de la tige de guidage.
