Definitions

  • the invention relates to a tool for releasing a connection between a grinding or polishing plate and a support plate of a grinding or polishing device, which connection is based on a hook-and-loop fabric.
  • the grinding or polishing plate is preferably flexible and is, for example, in the form of abrasive or emery paper, abrasive or emery fabric, a sheep's or lamb's wool bonnet, a sheep's or lamb's wool disc, a microfiber disc, a felt disc or a disc made of any other material suitable for polishing.
  • the tool comprises a grip portion, by means of which the tool can be manually gripped by a user, and a separation portion which is designed to be inserted between the tool plate and the support plate when said tool plate is being removed from said support plate.
  • a grinding or polishing plate is usually removably fastened to the support plate by means of a connection which is based on a hook-and-loop fabric (in the manner of a hook-and-pile fastener or Velcro®).
  • the connection which is based on a hook-and-loop fabric is similar to a hook-and-pile fastener connection.
  • a layer of fabric comprising a plurality of hooks is, for example, attached to the grinding or polishing plate, whereas a layer of fabric comprising a plurality of loops is arranged on the support plate of the grinding or polishing device. Pushing the grinding or polishing plate onto the support plate causes the hooks to connect to the loops in the respective layers of fabric, as a result of which the grinding or polishing plate and the support plate are connected in a rigid manner, but also such that the connection can be released by peeling the plates apart.
  • Changing the grinding or polishing plate which is a frequent process during the operation of the grinding or polishing device, requires that the grinding or polishing plate be removed from the support plate.
  • the grinding or polishing plate is manually taken off by the user of the grinding or polishing device, or tools which are provided, per se, for different purposes, such as a screwdriver, are instead used for this purpose.
  • Manually taking off the grinding or polishing plate is often a laborious and difficult process.
  • Using a screwdriver, for example is disadvantageous in that the support plate and/or the layer of fabric on the support plate is at risk of getting damaged. On the one hand, this makes it more difficult to connect a new grinding or polishing plate to the support plate or the strength of a connection of this kind is thereby reduced.
  • the aim of the present invention is therefore to provide a tool of the above-mentioned type by means of which the grinding or polishing plate can be safely taken off the support plate of the grinding or polishing device, without this posing the risk of the support plate getting damaged.
  • This object is achieved by a tool according to claim 1 .
  • the tool according to the invention is characterized in that the separation portion has a rounded tip. This rounded tip makes it possible for the separation portion to be inserted between the tool plate and the support plate when said tool plate is being removed from said support plate, such that the support plate is prevented from getting damaged in an effective manner, since the tip of the separation portion is rounded and does not have any sharp edges.
  • the separation portion is rounded off.
  • the regions which could be the edges of the separation portion are, in any case, rounded such that there are no sharp edges on the separation portion.
  • “rounded off” is in this case understood to mean that the separation portion does not have any sharp edges, such as two straight surfaces which meet at an angle.
  • all of the edges of this kind are rounded, the rounding being such that it is not possible for one of the aforementioned edges to damage the support plate. This is advantageous in that, after the tool has been inserted, it is also possible for said tool to safely rotate between the grinding or polishing plate and the support plate, without the support plate getting damaged.
  • the edges of the separation portion are rounded such that the radii of the rounded regions of the separation portion are greater than 0.5 mm, in particular greater than 1 mm, more particularly greater than 1.5 mm.
  • the separation portion is particularly preferable for the separation portion to be flat. What is meant by this is that the extension of the separation portion in one plane is substantially greater than the extension thereof in a direction orthogonal to this plane.
  • the separation portion can be inserted between the grinding or polishing plate and the support plate, as a result of which the grinding or polishing plate and the support plate are separated from one another in an extensive manner merely as a result of the separation portion being inserted, without said separation portion having to be moved along the support plate.
  • the separation portion it is also advantageous for the separation portion to have a thickness that is smaller than the thickness of the grip portion.
  • the separation portion it is not compulsory for the separation portion to be of substantially the same thickness over the entire extension thereof.
  • the separation portion has virtually no thickness and is virtually completely planar, and can therefore advantageously be inserted between the grinding or polishing plate and the support plate, without causing any damage thereto, and the grinding or polishing plate can be pried off the support plate.
  • the separation portion it is also advantageous for the separation portion to have a thickness which decreases from the end of the separation portion that is on the grip portion side towards the tip of the separation portion.
  • the separation portion effectively tapers off when viewed from the grip portion towards the tip.
  • the separation portion has its lowest thickness at the tip, as a result of which it can easily be inserted, tip-first, between the grinding or polishing pate and the support plate.
  • the separation portion increases in thickness towards the grip portion, as a result of which, when the separation portion is pushed between the grinding or polishing plate and the support plate, the grinding or polishing plate is automatically lifted off the support plate as a result of the increasing thickness of the separation portion along the longitudinal extension thereof.
  • the separation portion has a first narrow side and a second narrow side, the first narrow side extending such that it is outwardly curved and the second narrow side extending such that it is inwardly curved.
  • the separation portion is thus designed in the manner of a bent blade of a sword or dagger.
  • the outwardly curved narrow side advantageously makes it possible to cause the grinding or polishing plate to be detached by pivoting the separation portion (moving the tool in parallel with the main direction of extension of the flat separation portion) between the support plate and the grinding or polishing plate, whereas the inwardly curved second narrow side allows the tool to be produced in a cost effective manner because it means that material can be saved and it is simpler to remove said tool from the mold.
  • the first narrow side it is also advantageous for the first narrow side to have a smaller thickness than the second narrow side.
  • the detachment of the grinding or polishing plate by pivoting the sword or dagger-like separation portion is further improved, since the separation portion can be pivoted between the grinding or polishing plate and the support plate after having been inserted between the grinding or polishing plate and the support plate by its thin first narrow side first, and this results in the grinding or polishing plate being detached from the support plate in a particularly efficient and extensive manner.
  • the tip of the separation portion is arranged so as to be laterally offset from a longitudinal axis of the tool.
  • This asymmetrical design of the separation portion results in an advantageous separation effect when the polishing or grinding disc is being removed from the support plate, in particular by means of the above-mentioned curved narrow sides.
  • the separation portion effectively operates in the manner of a sword, except that it does not cut but rather merely forces open and releases the connection between the polishing or grinding disc and the support plate, which connection is based on a hook-and-loop fabric.
  • the separation portion can be inserted and pulled through between the grinding or polishing plate and the support plate in a particularly efficient manner, and the connection between said grinding or polishing plate and said support plate can be released in a particularly smooth manner.
  • an insert element which is detachably or irremovably connected to the tool is arranged in the region of the grip portion.
  • surface properties of the grip portion can be set by accordingly selecting the material of the element which is detachably or irremovably connected to the tool, whereas a main part of the tool can effectively be produced from another material which may be cheaper.
  • an advantageous variant of the tool is characterized in that the element which is detachably or irremovably connected to the tool comprises a debossed symbol, in particular a trademark of a manufacturer of the grinding or polishing device.
  • the main part of the tool can be universally produced and the element which is detachably or irremovably connected to the tool can be subsequently attached thereto and, when the logo to be applied changes, it is only necessary to adapt the production of the element which is detachably or irremovably connected to the tool. This means that the production of the tool can be adapted to customer requirements in a flexible manner and on an individual basis.
  • a subregion of a surface of the grip portion in particular an element which is arranged in the region of the grip portion and is detachably or irremovably connected to the tool, is made of a polymeric material, preferably rubber, the surface in said subregion having a higher coefficient of static friction, with respect to a glove material or a human hand, than a surface of the separation portion.
  • the grip portion is particularly slip-proof and can be gripped in a particularly secure manner. This increases the safety when the tool is being used.
  • the separation portion comprises at least one recess.
  • a recess of this kind simplifies the production of the tool, since a tool having a corresponding recess can be removed from an injection mold, for example, in a simpler manner.
  • the material thickness of the tool is not too high, and therefore the tool can cure in a quick and dimensionally stable manner following injection molding, without a high degree of material shrinkage.
  • the recess improves the separation performance of the tool because said tool can be pushed between the polishing or grinding disc and the support plate in a simpler manner.
  • the recess it is preferable for the recess to be channel-like and to generally extend from the grip portion towards the tip of the separation portion. As a result, the tool can be pushed, tip-first, between the polishing or grinding disc and the support plate in a particularly simple manner.
  • the recess prefferably has an extension in the direction of the longitudinal axis of the tool that corresponds to at least 50%, in particular at least 60%, of the extension of the separation portion along the longitudinal axis. This ensures that the advantages provided by the recess, in particular when the tool is being removed from the injection mold, are offered over the most part of the separation portion.
  • the grip portion has an ergonomic shape and is in particular flat.
  • the tool can be produced in a manner in which material is saved and can be held and transported by a user in a particularly simple manner.
  • the grip portion prefferably has an hourglass-shaped cross section in the plane of its flat extension parallel to a longitudinal axis of the tool. As a result, the grip portion can be gripped in a secure manner and it is virtually impossible for the tool to slip out of the user's hand.
  • a cleaning portion is arranged on an end of the grip portion that is remote from the separation portion, at least one cleaning blade and/or bristles of a cleaning brush being arranged in the cleaning portion. If dirty, the grinding or polishing disc can be cleaned by means of the cleaning brushes and the cleaning blades, and therefore does not need to be replaced as regularly.
  • the cleaning portion is used to remove dust residues, dirt residues, residues of an abrasive or polishing agent, or other residues from the grinding or polishing disc.
  • material e.g.
  • the cleaning portion can be used to remove this material quickly and effectively.
  • the combination of the tool for removing the grinding or polishing plate and for cleaning the grinding or polishing plate is particularly advantageous in that the user of the grinding or polishing device only has to carry a single tool with them in order to perform both tasks.
  • a combination of the cleaning brush and the cleaning blades results in particularly efficient cleaning. This combination means that different types of soiling, including in particular soiling that is particularly tenacious, can be removed in a single cleaning step.
  • the bristles of the cleaning brushes advantageously consist of polyamide or horse hair. This makes the bristles robust, durable and efficient in terms of their cleaning effect.
  • the at least one cleaning blade prefferably has a meander-shaped cross section in the plane of a flat extension of the grip portion or to generally extend in parallel with the longitudinal axis of the tool.
  • the cleaning blade cleans in a particularly efficient manner.
  • the cleaning blade extending in parallel with the longitudinal axis allows there to effectively be a wiping movement when the cleaning portion is being used transversely to the longitudinal extension of the blades, without the user having to grip onto the tool.
  • the at least one cleaning blade is formed in one piece with the insert element which is detachably or irremovably connected to the tool.
  • the cleaning blade and the element which is irremovably connected to the tool are injection molded onto the main part of the tool in one working step.
  • the cleaning blade and the element which is detachably connected to the tool be produced in one piece in one working step in the injection molding process, and subsequently attached, preferably clipped or glued, to the main body of the tool in a further working step.
  • the main part of the tool is preferably produced from a thermoplastic polymer.
  • preferred polymers for producing the main part are polypropylene and polyamide.
  • the insert elements which are detachably or irremovably connected to the tool are produced using a thermoplastic elastomer.
  • Urethane-based thermoplastic elastomers are preferred.
  • Preferred urethane-based thermoplastic elastomers are Elastollan (from BASF), Desmopan, Texin and Utechllan (from Bayer).
  • the use of styrenic block copolymers is also preferred, in particular the use of Kraton (from Kraton Polymers), Septon (from Kuraray), Styroflex (from BASF), Thermolast (from Kraiburg TPE) or Saxomer (from Polyplast Compound Werk, PCW).
  • the cleaning blade(s) it is advantageous for the cleaning blade(s) to be produced in one piece with an insert element which is detachably or irremovably connected to the tool, the use of the aforementioned plastic materials, in particular the production of the unit consisting of the cleaning blade(s) and the insert element in an injection molding process using said plastics materials, being advantageous.
