    The invention relates to a hand grinder, which consists of flexible material. The base plate is hand-shaped, on the underside of the base plate is a climbing attached to which the sandpaper adheres. In the base plate there are longitudinally slits opening into the overhead suction bars, which in turn are connected to the bellows air cushion and the suction nozzle. The suction pipe is connected to the hose leading to the vacuum cleaner. The handle on the upper side results from the left and right side wall as well as from the webs, which lie between the fingers. The side exhaust is located between the thumb and forefinger.

    The invention relates to a flexible hand-held sander with extraction, which processes all types of surfaces of any material in which small, narrow, bent or round workpieces or objects or their surfaces have to be ground / matted can. According to the prior art, there are currently only rigid sanding blocks with suction, but with which no narrow or angular spaces, curves, surfaces and the like can be edited. All narrow, winding and small spaces or curves must therefore be processed again conventionally with the hand and held in the hand sandpaper without the dust particles and chips can be sucked directly. As a result, however, quantities of dust particles / shavings that are detrimental to the respiratory tract and the eyesight of the worker act directly on the worker. Additional protective equipment (masks, goggles, etc.) must be used to cause inconvenience at work and reduce labor productivity. In addition, the sandpaper is thereby bonded with dust particles / chips within a short working time and dust particles and chips adhere to the work surface and

Furthermore, the immediate environment is contaminated in the workshop, which requires additional cleaning work. The disadvantage of the already known sanding block is that in the course of the grinding / matting work no narrow, winding or round, difficult to access surfaces can be processed. The object of the invention of the flexible sanding pad is to grind / matt all narrow, winding, hard to reach areas and curves and thereby directly suck the dust particles and chips, to provide optimal safety, without additional protection (glasses, masks) use and to increase the service life of the sandpaper and to keep the cleaning work on the object and in the work space as low as possible. This object is achieved with the features of claim 1. This is a flexible, hand-held grinding device of a suitable, movable, thin and flexible material of any kind, to which the mounted on the underside of the base plate 1 sandpaper under the action of the hand of the surface of the workpiece to be machined optimally adapts. The fact that the flexible sanding pad has the shape of a palm and the base plate 1 is chamfered on one side, even flat surfaces can be well edited and the 3rd
    Processing in curves and in edges and angles are optimally possible. The webs are not higher than the edge of the hand, which is why you can drag into small gaps.
    In order to prevent the occupational safety (dust formation and exposure to the worker and MAK values) and the early sticking of the sandpaper (brings an increase in the service life), a suction device 2,3,4,7,8 is included in the flexible sanding pad ,
    This is realized in such a way that openings are provided on the base plate 1 and in the sandpaper mounted thereon in a certain arrangement, through which the resulting dust particles / chips are sucked off. These dust particles / chips are derived by channels suitably housed in the lands 2,3,4. These webs 2,3,4 also serve at the same time the better, ergonomic hand position / handling of the flexible sanding pad. These three channels in the webs 2,3,4 open into a bellows / air cushion 7, which is ergonomically fitted below the palm. Also below the bellows / air cushion 7 are suction.
    The dust particles / chips are sucked through a suction nozzle 8, which is arranged between the thumb and forefinger. The connection is standardized to ensure easy compatibility with existing hose connections.
    The channel is guided by the bellows / air cushion 7 between the thumb and forefinger upwards towards the top of the hand and further across the top of the hand to the outside. The connected suction hose can thus be guided behind the body of the worker. The ergonomic shape of the suction 8 supports the shape of the webs 2,3,4 and the side walls 5,6 good handling.
    The technical result is the ability to extract dust particles / chips and small mechanical particles in the course of the grinding / matting work so as to improve the occupational safety, increase the life of the abrasive paper and minimize unnecessary contamination of the working surface and working environment.
    [0014]
    The invention will now be explained with reference to the sketch:
    Figure 1 illustrates the floor plan of the flexible sanding pad (top view).
    On the base plate (1), the left (5) and the right (6) side wall can be seen. Evident are air suction ducts, which are housed in the three bars left (2), center (3), right (4). Furthermore, the suction nozzle (8) and the bellows / air cushion (7) can be seen.
    [0015]
    Figure 2 shows a view of the flexible sanding pad of Figure 1 from below, wherein on the base plate (1) of the suction nozzle (8) and the suction openings (9) can be seen.
    Figure 3 shows the sectional view, in which case the right and left side wall (5, 6), the three webs (2,3, 4), the bellows / the air cushion [0016] 5 (7) and the suction nozzle (8) cut to see are.
    [0018]
    The invention works as follows:
    The worker places her hand in the top of the sanding pad, turns on the vacuum cleaner and guides the flexible sanding pad to the work surface to be sanded.
    By the nature of the invention, it is possible to grind / frost all narrow, winding, hard to reach areas and curves and thereby the dust particles / chips that form during grinding, by means of the Luftsaugstromes of the vacuum cleaner through the
    Sanding holes / suction through the integrated channels in the webs via the suction hose into the vacuum cleaner.
    [0019]
    The present invention makes it possible to operate without the use of protective means (masks, etc.), thereby increasing the productivity of the worker, since the wearing of protective agents that make breathing difficult can be avoided, and the invention also extends the service life (service life) of the sandpaper.
    [0020]
    In addition, the working surfaces and also the objects that are in the immediate vicinity remain dust particles / chips-free, since they are directly sucked off. An additional cleaning of the machined surface and, if necessary, the workshop, an additional operation, is thereby unnecessary and in turn saves working time.
