Embodiment Construction

[0019] exist figure 1 In the center, the surface structure of the mating attachment device of the receiver body and of the grinding element can be seen in a strongly enlarged detail. Here, a first attachment device 1 which is connected to the upper side of a receiving body 11 (schematically shown) of the grinding device is connected to an exchangeable grinding element 12, for example a grinding disc (schematically shown). The second attachment device 2 on the back side of the is in engagement. The first attachment means 1 and the second attachment means 2 have a plurality of protrusions 3 of the same shape and size, which project from the bases 4 , 5 of the attachment means 1 , 2 at regular intervals from each other. The protrusions 3 are shaped in the shape of a thickened rod, wherein the cross-section of each protrusion 3 expands substantially continuously from its shank 6 to its free end 7 . The size of the protrusions 3 is only a few tenths of a millimeter. When the fir...

Abstract

The invention relates to a grinding device, comprising a mounting body which is detachably connected to a grinding element, said detachable connection being designed such that the mounting body has a first adhering arrangement and the grinding element has a second adhering element and the adhering elements correspond in the manner of a Velcro fastener. The aim of the invention is to improve the quality and efficiency of the detachable connection for exchange of the grinding element of the claimed grinding device. Said aim is achieved, wherein the first adhering element (1) and the second adhering element (2) comprise a number of projections (3) each with a cross-sectional widening in the direction of the free end (7) of the projection (3).

Description

technical field [0001] The invention relates to a grinding device having a receiving body which is releasably connected to a grinding element, wherein the releasable connection is formed in such a way that the receiving body has a first An attachment means, the grinding element has a second attachment means and these attachment means correspond to each other in the form of a hook-and-loop closure. Background technique [0002] Various grinding devices are known in grinding technology, which use exchangeable grinding elements, especially grinding discs, for example in hand-held tools such as triangle grinders, superfinishing grinders or in a circular grinding machine. In order to replace quickly worn-out grinding discs with new grinding discs uncomplicatedly and quickly, on the one hand on the upper side of the receiver, for example formed by the grinding disc, on the other hand on the grinding disc Attachment partners arranged in pairs in the form of flat hook-and-loop clo...
