Definitions

  • the invention relates to a grinding tool, in particular for grinding uneven surfaces, made of flexible material in the form of a shoe which receives an end section of an extremity of a user or a part thereof and which is coated with an abrasive.
  • Such a grinding tool is known from AT 381 057 B, in which grinding surfaces are attached to the inside of a glove by means of a Velcro fastener. mechanical adhesive elements are provided on each finger and on the palm, on which an abrasive paper is then attached, which also has mechanical adhesive elements on the non-abrasive side. The dimensions of the sandpaper are much larger than the glove.
  • This grinding tool has the disadvantage that the user cannot work and grind surfaces sensitively and in a controlled manner, since he only has direct pressure contact with the abrasive in the glove. Working in corners is difficult to carry out and furthermore, residues of abrasion can accumulate on the areas not under pressure and impair the quality of the grinding.
  • US-A-3,643,386 teaches a preferably waterproof glove made of rubber, on which grinding surfaces are glued to the fingertips and / or the palm.
  • a rubber-like adhesive after drying is intended to ensure that the glove is watertight against damp environments.
  • the fastening of the grinding surfaces by means of a rubber adhesive has the advantage according to US-A-3,643,386 that no holes have to be provided in the glove in order to fix the grinding surface.
  • WO 91/18 713 teaches a sack-like grinding tool in which the sack consists of three layers, all of which are superimposed on one another and thereby form a rectangle, the shorter side of which is opposite the open side tapered. Two of these layers, an abrasive layer and a layer forming the inner glove, are glued together. At their edges they are connected to a third layer which forms the upper glove. A bag-like glove has thus been formed, into which a user can insert his hand and then polish a surface by pressing on the double-layered inside.
  • the pointed shape is said to enable working in room corners.
  • this glove does not have any means which allow a safe sanding by pulling it back and forth in the corners, so that the sanding success is not guaranteed.
  • abrasion residues can accumulate on the surfaces not subjected to pressure and thus impair the quality of the grinding.
  • the professional craftsman or the hobby craftsman usually holds the sandpaper or abrasive cloth to be used and grinds the workpiece by moving it with this hand.
  • the sanding paper can slip out of your hand if you apply a little more pressure. With a strong grip around the abrasive, the hand cramps and the grinding result is impaired. When the hand slips off, the craftsman can injure himself on the workpiece, because one has to do without work gloves because of the more direct and better hand contact. Since the craftsman cannot concentrate on the pure grinding process for the reasons given above, the grinding result suffers.
  • grinding blocks are offered in the prior art, which are coated with an abrasive or span this. These aids also have disadvantages. It cannot be sanded gently because there is no direct hand contact with the workpiece. The grinding block or the grinding block cannot follow the workpiece on an uneven surface, so that such objects can only be ground with difficulty.
  • the invention has for its object to provide a grinding tool of the type mentioned, with which any surface can be ground without restricting the grinding options on uneven surfaces, without risk of injury to the user and without a loss of feeling occurring during grinding .
  • This object is achieved according to the invention with a grinding tool according to the preamble of claim 1 in that the abrasive is applied electrolytically or chemically to the current-conducting elements acting in the base material of the grinding tool.
  • a sack-like, glove-like, shoe-like or finger-like tool designed in the shape of a mitten is coated directly with an abrasive, the tool can be tightened over and on the hand and, if necessary, firmly strapped on, so that the glove protects the hand and itself adapts equally to the body part and the workpiece.
  • the grinding tool can then no longer slip out of the hand in the applications mentioned, so that the risk of injury is significantly lower, and depending on the type of abrasive, weaker or stronger tissue can be used for the glove.
  • the grinding tools can be designed, for example, as gloves, mittens, handbags, finger cots and consist, for example, of leather, plastic, textile materials, metal, or combinations of the materials mentioned, for example of metal-reinforced textile fabric with leather inserts.
  • Corundum or similar abrasives based on synthetic resin can be used as the abrasive.
  • basic materials such as plastic fabrics or natural materials are chemically or electrolytically coated with fine fragments of glass, diamond, sapphire or ruby.
  • the grinding tool can be coated with any grain size in order to produce different surface qualities.
  • the glove 1 has current-conducting elements that are active in the base material of the grinding tool. These can be realized by sewing on a metal net on the glove 1 during manufacture. Furthermore, the glove itself can consist of such a metallic mesh or of a plastic or natural material mesh which is coated with metal e.g. is worked in the form of metal threads on predetermined surfaces. Depending on the coarseness of the net, the interstices are then filled with a flexible mass so that the net cannot hang onto the interstices and then tear.
  • the metallic mesh is extended over the entire ball of the hand and the inside of the fingers. This net is now directly coated with abrasive material on the side opposite the palm of the hand.
  • the abrasive 4 is chemically or electrolytically applied to the current-conducting elements in the base material of the grinding tool, so that there is a firm and permanent connection between the abrasive 4 and the glove 2.
  • the abrasive 4 is applied and nickel-plated.
  • Steel strands are advantageously used as current-conducting elements.
  • Ruby, diamond, sapphire, glass, corundum or carbide materials are preferably used as the abrasive 4, although of course other abrasive materials can also be used.
  • FIG. 2 shows an abrasive glove 1 according to a second exemplary embodiment of the invention, which is partially coated with abrasive material on the side opposite the palm of the hand.
  • two areas 14 are provided on the ball of the hand with such a metallic mesh or with a knitted plastic or natural material mesh, to which the abrasive is then chemically or electrolytically applied.
  • the regions 14 and 24 can be provided alone with a mesh knitted for the electrolytic or chemical coating, or the entire glove 1 can be made of this material, and only those with the reference numerals 14 can be made with the aid of corresponding covering masks or with corresponding insulating coatings and 24 designated areas with the abrasive.
  • the glove 1 according to FIG. 2 which is only coated with abrasive at predetermined points, allows an embodiment tailored to the special needs of the craftsman, which offers greater comfort because the articulation points between the hand and fingers are from the abrasive and possibly from the net be kept free.
  • abrasive elements can be detachably attached to the grinding tool. This can be ensured by using Velcro fasteners or analog mechanical fasteners. This makes a glove 1 according to FIG. 2 in a few Handles on a glove 1 according to FIG. 1 convertible, which now has a larger processing area with greater stiffness of the glove 1.
  • FIG. 3 shows a schematic view of a hand of a user of the grinding tool according to FIG. 1, which grinds a round rod 6. From this it can be seen immediately that an excellent fit is given, since the metallic mesh advantageously forms a one-piece element of the glove 1.
  • FIG. 4 finally shows a grinding finger 34 which is completely covered with grinding material. It can be put on like a thimble and can be used for grinding in tight and difficult to access places. It is also possible that the finger cot is put on a glove. A small part of the sensitive contact of the user with the surface to be ground is lost. However, the user gains work safety through the protected hand and the finger cot can be stretched by pulling it over the glove finger before putting on the glove by the user, so that it sits securely and seems firmly connected to the corresponding finger of the user.
  • the described work glove 1 can also be provided in another embodiment for another end section of an extremity of a user or a part thereof, in particular as a sack, glove or mitten for the hand, as a finger cot for the part of a hand or as a foot glove for the foot of one Be trained user
  • a foot shoe is shown in the drawings, it is easy to understand that with a corresponding foot shoe significantly larger frictional forces can be transferred to larger areas, although the grinding tool can be used in relatively small gaps or corners of large workpieces to be machined .
