Definitions

  • Grinding block for manual use and system comprising grinding block and grinding articles
  • the invention relates to a grinding block for manual application, in particular for manual grinding of surfaces.
  • Sanding is known as the surface treatment of products or objects in various industrial areas such as carpentry and the automotive industry. Sanding can be used for various purposes, such as polishing, smoothing, shaping surfaces, repairs or for special applications, such as removing a layer of paint or surface sanding of a spatula from a body.
  • Tools for grinding are fundamentally characterized by the presence of a grinding surface provided with abrasive substances, which is brought into contact with the surface to be treated, which is thereby machined. This can be done manually or mechanically. Furthermore, a tool for manual grinding generally has a surface for gripping the tool. Grinding blocks are already known which are intended for manual use, in particular for manual grinding of surfaces, and which have at least one base plate for holding an abrasive article and at least one grinding block body with a grip area, for example from EP 11182793 A1. It is also known to design grinding blocks in such a way that they are compatible with commercially available 150 mm grinding wheels, which are actually designed for random orbit sanders, and can therefore be used for hand sanding.
  • the invention relates to a grinding block for manual application, in particular for manual grinding of surfaces, comprising at least one base plate for holding an abrasive article and at least one grinding block body with a grip area.
  • a battery-operated device for suction of grinding dust is integrated into the grinding block, which comprises at least one dust box, a motor housing in which a drive motor provided with a fan wheel is provided, and a battery for mains-independent power supply of the drive motor.
  • a grinding block is used for manual application, in particular the manual grinding of surfaces.
  • the sanding block is also known as a sanding block and differs from orbital and eccentric sanding devices, in which automated or motorized sanding is realized by using a motor that drives a motorized base plate that is movably mounted to the orbital and eccentric sanding devices. Therefore, in the context of this document, a grinding block is to be understood explicitly in such a way that it does not have a motor for motorized execution of the grinding process. In this sense, the grinding block is used for manual application and manual grinding.
  • the grinding block has a grinding block body, which in one embodiment of the grinding block can be realized as a housing of the grinding block.
  • the grinding block body also has a grip area.
  • the grip area is used by a user to firmly grip the grinding block so that it can be guided in a controlled manner during the execution of a manual grinding movement, in particular over a workpiece.
  • the grip area can be designed as a handle in one embodiment of the grinding block. Alternatively or additionally, the grip area can be at least partially rubberized in order to increase its grip.
  • a base plate of the sanding block is used to hold and attach an abrasive article to the sanding block, particularly while performing a sanding process.
  • the base plate is preferably designed as part of the grinding block body in one piece with this.
  • the base plate is designed to hold an abrasive article or can itself have at least one abrasive surface, comparable to a metal planer.
  • the base plate represents a substantially flat surface.
  • the base plate has a material layer suitable for forming a Velcro connection, for example a layer of loops or a layer of flexible barbs.
  • a battery-operated device for extracting grinding dust.
  • the battery-operated suction device is used to extract sanding dust that occurs during a sanding process in manual use of the sanding block.
  • the battery-operated device for suction includes at least one dust box, a motor housing in which a drive motor provided with a fan wheel is provided, and a rechargeable battery for the mains-independent power supply of the drive motor. In this way, grinding dust arising during a grinding process can be sucked off particularly efficiently using the battery-operated device for suction from the surface to be processed and collected in the dust box.
  • the drive motor is supplied with energy, at least in the switched-on state, by a rechargeable battery for the mains-independent power supply.
  • a rechargeable battery for the mains-independent power supply.
  • an accumulator package consisting of at least one electrochemical accumulator cell that supplies electrical energy.
  • the battery is, in particular, a rechargeable secondary battery that, when connected to a charging station, can be recharged.
  • batteries with cell chemistry that provide a high power and / or energy density are suitable for energy supply, such as battery mulators of lithium and lithium-ion cell chemistry, in particular lithium iron phosphate, lithium manganese oxide, Lithium-nickel-cobalt-manganese oxide, lithium-nickel-cobalt-manganese oxide, lithium-sulfur, lithium-polymer and lithium-oxygen batteries.
  • battery mulators of lithium and lithium-ion cell chemistry in particular lithium iron phosphate, lithium manganese oxide, Lithium-nickel-cobalt-manganese oxide, lithium-nickel-cobalt-manganese oxide, lithium-sulfur, lithium-polymer and lithium-oxygen batteries.
  • the grinding block is a particularly handy, always ready-to-use tool that can also be used or used in a clean environment, because due to the battery-operated device for suction, the risk of flying dust and in particular the risk of contamination of the environment is minimized is. Furthermore, due to the integrated battery-operated device for suction, a device for suction that is external to the grinding block can be dispensed with.
  • an external vacuum cleaner and / or a hose connection from an external vacuum cleaner to the sanding block can be dispensed with, which greatly impedes the use of the sanding block in a manual sanding movement.
  • the weight of the grinding block can advantageously be increased and balanced in such a way that the grinding block during a grinding process, i.e. with the manual grinding movement, lies very well in the hand of the user.
  • the dust box can be detachably fixed to the motor housing and the grinding block can be removed from the outside. In this way it can be realized that the dust box can be emptied as soon as it is filled with grinding dust. To do this, the dust box can be removed from the grinding block, emptied and then put back into the grinding block be introduced, again resulting in a releasable fixation on the motor housing.
  • the dust box can also be realized in the form of a flexible dust bag or the like, which can be detachably fixed to the motor housing. This dust bag can be stowed in the sanding block body or can be attached to the outside of the sanding block body.
