Definitions
- the present invention relates to a device for cleaning smooth surfaces according to the preamble of patent claim 1.
- the invention seeks to remedy this.
- the invention solves the problem of creating a device which facilitates the cleaning of heavily soiled smooth surfaces.
- the device according to the invention can also be used to effortlessly remove stubborn dirt.
- the vibratory drive for the washer has a very low weight, so that the operator is physically less stressed than when the dirt has to be removed from the disk by circular or upward and downward movements.
- the scraper arranged parallel to the washer With the scraper arranged parallel to the washer, the cleaning liquid remaining on the pane and the dirt dissolved in it can be continuously removed from the pane surface. The stripped liquid no longer drips onto the floor, but falls back on the washer. As a result, the washer remains moist for a very long time and the cleaning liquid can be replenished at much greater intervals than was previously the case.
- the vibration damping element inserted between the handle and the vibration drive prevents, on the one hand, the transmission of the vibrations to the handle and a telescopic rod which may be attached to the handle, and on the other hand it is possible to work with a lower vibration drive power, since the entire vibration energy is transmitted to the washer .
- the scraper which is fixed in and adjustable with respect to the washer, enables the device to be adapted to the respective work location (vertical or inclined surfaces) and to the wishes of the operator.
- FIG. 1 shows a perspective view of the device with the scraper fitted
- FIG. 2 shows another embodiment of the device in a side view
- FIG. 3 shows an oscillation course in circular movements
- FIG. 4 shows an oscillation course in translatory movements.
- a cylindrical washer 3 is fastened to the end of a handle 1 and covered with a jacket 5 made of lambskin or the like.
- a vibration drive 7 sits on the washer 3 and is connected to the washer 3.
- a vibration damping element 11 in the form of a wave-shaped curved spring can be inserted between the handle 1, which can have a joint 9, and the vibration drive 7.
- a scraper 13 with a lip-shaped edge 15 is also placed.
- the hump-shaped edge 15 lies parallel to the longitudinal axis of the washer 3. Energy can be supplied to the vibration drive 7 by means of a cable 15.
- the vibratory drive 107 is arranged in the interior of the tubular washer 103.
- a damping element 111 made of rubber or metal is inserted between the washer 103 and the end of the handle 101.
- the scraper 113 is connected to a fastening device, e.g. a wing nut 119, axially displaceably connected to the latter at the end of the handle 101, such that the angle alpha between the surface 121 to be cleaned and the axis of the handle 101 can be adapted to the respective requirements without the lip 115 being too strong or is pressed too little onto the surface 121.
- the washer wetted with water and / or cleaning liquid will perform a rotating movement according to FIG. 3 or a translational back and forth movement as shown in FIG. 4.
- the two movements according to FIGS. 3 and 4 can be superimposed by appropriate arrangement and design of the vibration drive 7, 107.
- Dirt adhering to the surface to be cleaned for example the disk 121, is mechanically detached by the small-stroke, but high-frequency movements.
- the mechanical detachment is supported by that when the washer 3 is pressed onto the jacket 5 cleaning liquid squeezed onto the disk 7, 21, 121.
- the cleaning liquid remaining on the disk and the dirt dissolved in the cleaning liquid are continuously drawn off from the surface by the lip 15, 115 of the scraper 13, 113.
- the liquid which has been drawn off is returned to the casing 5, 105 in drops 123 or as a clot along the surface of the pane and is there for further cleaning.
- the vibration drive can also be accommodated within the handle or connected to a drive standing on the floor via a flexible shaft if this is required by regulations of electrical monitoring associations.
