Definitions

  • the present innovation relates to a motor-driven brush for cleaning purposes, in particular for cleaning motor vehicle rims.
  • brushes are offered for cleaning smaller areas, all of which have no motor drive.
  • Known large-scale devices such as carpet cleaners having rotating flat brushes, are not suitable for working on small, and in particular not for cleaning angled surfaces or wet surfaces, since the rotating brushes throw off the liquid.
  • the present innovation has therefore set itself the task of creating a motor-driven brush which can be used in manual operation, which is suitable for working in particular on small and angled surfaces and in which the spinning off of liquid, cleaning agent or dirt is not observed or is greatly reduced.
  • a particularly important use of the present innovation is the cleaning of motor vehicle rims, which are often designed as filigree aluminum rims and are essentially inaccessible to rotating brushes in car washes.
  • the motor is preferably powered by a battery and thus independently of a power source.
  • the brush advantageously has a round head on the end face.
  • the bristle length is approximately one centimeter
  • the brush holder diameter is also approximately one centimeter, so that the overall diameter of the brush is approximately 3 centimeters.
  • the total length of the brush should be about seven centimeters.
  • a very simple motor drive for the brush consists for the present purpose of a crank pin, which is moved by the electric motor on a circular path and which engages in a fork connected to the shaft driving the brush, so that the fork reciprocates and so the brush drives reversing by the angle predetermined by the mechanics with the frequency of the crank pin rotation.
  • crank pin may be necessary to provide a reduction or transmission gear between the crank pin and the motor shaft, which in the simplest case is a spur gear reversal and the crank pin is eccentrically attached to the driven spur gear.
  • FIG. 1 shows a section through the device and FIG. 2 shows a brush variant.
  • REPLACEMENT LEAF Figure 1 shows a housing 6, in which a preferably battery-powered electric motor 4 is located.
  • This motor 4 drives a crank pin 10 directly or via a spur gear with first gear 8 and second gear 9, crank pin 10 rotating eccentrically.
  • the crank pin 10 engages in a fork 11 and swings it back and forth.
  • the fork 11 is arranged on a shaft 5 which is guided in the housing 6 in bearings 12, 13, so that the shaft reverses in the degree of fork deflection by the oscillating fork.
  • the shaft 5 is releasably connectable to a brush holder 1, e.g. B. by a clamp or a mechanical fuse 14 in a receptacle 3 of the brush holder 1.
  • the brush holder 1 is provided with bristles 2 which surround the carrier on all sides or in some areas ( Figure 2).
  • the brush is designed as a round head 7.
  • FIG. 2 shows an embodiment of the brush, in which the bristles 2 do not encompass the entire brush holder 1.
  • This variant is advantageous when gaps are to be cleaned, in particular those of motor vehicle rims, which often have ribs converging in a V-shape and the bottom of which is difficult or impossible to reach with a full brush.
  • the reversing vibratory drive according to the invention does not distribute cleaning agents significantly beyond the surface to be treated, there is also a desirable saving in chemicals when used.
  • the reversing rotary stroke is determined in such a way that when the brush holder 1 is pressed onto a surface to be cleaned, the bristles 2 perform a particularly smooth working movement with their free bristle end relative to the surface to be cleaned.
  • the diameter, the length and the material of the bristles 2 are determined so that the
  • bristles 2 Despite bending when the brush holder 1 is pressed on, bristles 2 transmit this working movement to the surface to be worked by bending back and forth.
  • the pressure forces when working with the brush must be adapted to the behavior of the bristles 2 or the brush holder 1 within certain limits.
  • a turning stroke from turning point to turning point of the brush holder 1 of 0.5 to 2 cm, measured at the ends of the bristles, with a bristle length of about 1 cm and a diameter of the brush holder of about 1 cm is also advantageous.
  • the bristles of the brush holder are approximately 0.5 cm long, the brush holder itself having a diameter of approximately 2 cm and having a swivel stroke of approximately 0.5 cm, and the swivel stroke not being less than Should be 0.2 cm.
  • the maximum speed of the gear 9 carrying the crank pin 10 is not significantly above 500
  • the rotational stroke of the brush holder or the driven shaft and the speed of the motor can also be adjusted in a variable manner.
  • An advantageous embodiment of a brush holder has a sponge-like absorbent textile or foam jacket which is slightly thinner than the length of the bristles and which is penetrated by the bristles on narrow openings arranged in a matrix, so that the bristle tips overlap stick out the foam jacket.
  • the bristle shaft is supported in the center, tightly enclosed by the openings in the jacket. Thereby possible vibrations of the
  • the bristles are damped when they spring back from their bending position during the working stroke to their extended position, the bristle tips detaching from the workpiece.
  • the jacket prevents cleaning liquid and the like from splashing away. The loss of fluid is also particularly low because the foam jacket as
  • Liquid depot is used.
  • the brush holder is axially longitudinally movable, in particular resiliently arranged, so that hard axial impacts on the workpiece are avoided during cleaning work.
  • the reversing movement of the brush holder is also superimposed with an axial oscillation, the reversing and
  • Axial vibrations have different frequencies, so that dirt particles are attacked by the bristles from all sides.
  • a differently designed, reversibly driven means can also be used to drive the brush holder.

Abstract

L'invention concerne une brosse entraînée par un moteur, destinée notamment au nettoyage de jantes d'automobiles. Cette brosse comporte un support (1) sur lequel sont disposés des poils (2). Elle permet un nettoyage particulièrement soigneux et évite de salir les alentours de l'objet à nettoyer, par exemple par projection de produit de nettoyage ou de liquide. Le support (1) présente à son extrémité sans poils (2) un logement (3) dans lequel peut s'emboîter un arbre entraîné selon un mouvement alternatif par un moteur électrique (4), le carter (6) entourant le moteur (4) étant conçu sous forme de poignée.
