Definitions
- the invention relates to a Schleifvorhchtung with a
- a receiving body which is releasably connected to a grinding element, wherein the releasable connection is formed by the receiving body having a first adhesive assembly and the grinding element has a second adhesive arrangement and the adhesive assemblies in the manner of a hook and loop fastener with each other.
- various grinding devices which use interchangeable grinding elements, in particular abrasive sheets, for example in hand tools such as the delta sander, the orbital sander or the external grinder.
- abrasive sheets for example in hand tools such as the delta sander, the orbital sander or the external grinder.
- For the uncomplicated and quick change of the rapidly consumed abrasive sheets against abrasive sheets with new abrasive come on the one hand at the top of the receiving body, which is formed for example by a sanding pad, and on the other hand on the underside of the sanding sheet paired adhesive partners in the manner of a flat hook and loop fastener, which realize an easily detachable connection.
- the adhesive surface pair of the known from the prior art hook and loop fastener has variously designed surface structures.
- One of the two adhesive surfaces consists of a material with a plurality of small hooks, analogous to a burdock, wherein the counter-adhesion surface of wooly material is formed with a plurality of small loops.
- the adhesive surface with the soft loop material is preferably arranged on the underside of the abrasive sheet, whereas the somewhat stiffer adhesive surface with the hook is usually associated with the receiving body.
- Velcro requires due to the differentiated surface structures of the two Haftpartner various materials and manufacturing processes that make the overall production complex and expensive.
- the conventional Velcro fastener in particular in its application for grinding devices with frequently changing Consumables, such as grinding sheets technically and economically as an improvement.
- the invention is therefore based on the object to improve the quality and efficiency of the releasable connection for replacement of the grinding element of the generic grinding device.
- both the first adhesive assembly and the second adhesive assembly has a plurality of projections each having an increasing towards the free end of the projection cross-sectional widening
- both adhesive arrangements have the same surface structure, so that the production of the closure is greatly simplified and cheaper.
- a detachable connection is more comfortable, more efficient and with less effort to produce than conventional hook-and-pile closures. Therefore, this releasable connection offers a good use in a grinding device with interchangeable grinding elements.
- the protrusions may also be varied in size, shape, spacing, and / or materials, as long as the releasable rear grip is always ensured.
- the adhesive properties of the adhesive arrangements can be adjusted very precisely to a wide variety of application and load cases of the detachable connection to a variety of grinding devices.
- the first adhesive arrangement is releasably connected to the receiving body.
- the receiving body associated with the first adhesive assembly is not firmly adhered to this, but releasably connected. So can the at constant change of abrasive elements most frequently mechanically loaded adhesive arrangement are easily replaced.
- Adhesive arrangement is formed.
- the sanding pad serves to dampen the mechanical loads occurring during sanding, in particular the vibrations that are transmitted from the machining object to the sanding device, and therefore usually consists of hard rubber or similar elastic material.
- This material is suitable at the same time for the formation of the projections of the adhesive arrangement, since an elasticity of the projections of the releasable connection according to the invention between the adhesive arrangements gives a higher ease of closing and opening.
- the detachable connection of the sanding plate to the base body is formed by the base body having a third adhesive arrangement according to the first adhesive arrangement and the sanding plate having a fourth adhesive arrangement according to the second adhesive arrangement
- the detachable connection according to the invention can also be used for fastening the sanding plate to the base body . Since the positive connection of the closure according to the invention produces good holding forces, this type of connection is also suitable at a location of the grinding device on which the demands on the holding force, eg due to higher leverage, increase.
- FIG. 1 is a schematic, greatly enlarged view of the releasable connection between a receiving body and a grinding element.
- Fig. 1 the surface structure of the interlocking adhesive arrangements of the receiving body and the grinding element can be seen in a greatly enlarged section.
- a first adhesive assembly 1 which is connected to the top of a receiving body 11 of the grinding device (indicated), in engagement with a second adhesive assembly 2, on the back of the interchangeable grinding element 12, for example, an abrasive sheet (shown indicated), respectively is.
- the first adhesive assembly 1 as well as the second adhesive assembly 2 have a plurality of uniform and equally sized projections 3 which protrude at a uniform distance from each other from the base 4, 5 of the adhesive assemblies 1, 2.
- the projections 3 are shaped like a club, wherein the
- each projection 3 is extended from its shaft 6 to its free end 7 substantially steadily.
- the projections 3 are only a few tenths of a millimeter in size.
- the projections 3 push each other in opposite directions and enclose each other.
- the adhesive assemblies 1 and 2 respectively penetrates a projection of an arrangement between projections of the other arrangement and vice versa, wherein the free end portions of the projections 3 form chamfers and thus facilitate the assembly.
- the projections of the two adhesive arrangements 1 and 2 are laterally adjacent to each other.
- the projections 3 of the two detention arrangements 1 and 2 engage behind each other, since in each case the diameter-largest area is followed by a smaller-diameter area due to the club shape. Accordingly, the cross-sectional widening head shape of the projections 3 provides for easy joining of the projections 3 and the cross-section of the respective larger cross-sectional decreasing shape provides the necessary closure of the connection.
- This type of three-dimensional design of both adhesive assemblies 1, 2 has the above-described advantageous properties that qualitatively improve the releasable connection between the receiving body 11 and the grinding member 12 of the grinding device.
