Sanding Block for Manual Use, and System Comprising a Sanding Block and an Abrasive Article

Abstract

The disclosure relates to a sanding block for manual use, in particular for manually sanding surfaces, having at least one base plate for holding an abrasive article and at least one sanding block body having a gripping region. According to the disclosure, a rechargeable-battery operated device for removing sanding dust by suction is integrated in the sanding block, said device comprising at least a dust box, a motor housing, in which a drive motor provided with an impeller is provided, and a rechargeable battery for supplying the drive motor with power without an external power supply.

1 . A sanding block for manually sanding surfaces, comprising:
 at least one base plate configured to hold an abrasive article;   at least one sanding block body having a grip region; and   an accumulator-battery-operated mechanism configured to suction-off sanding dust,   wherein the accumulator-battery-operated mechanism includes (i) at least one dust box, (ii) a motor housing, in which there is provided a drive motor having an impeller wheel, and (iii) an accumulator battery configured to supply electric power to the drive motor.   
     
     
         2 . The sanding block as claimed in  claim 1 , wherein the dust box is configured to be detachably fixed to the motor housing and removed from the sanding block from the outside. 
     
     
         3 . The sanding block as claimed in  claim 1 , wherein the accumulator battery is configured to be detachably fixed to the sanding block body and removed from the sanding block from the outside. 
     
     
         4 . The sanding block as claimed in  claim 1 , wherein the accumulator battery and/or the dust box is configured to be received, at least partially, in the grip region of the sanding block. 
     
     
         5 . The sanding block as claimed in  claim 1 , further comprising a control element configured to switch the drive motor on and off, wherein the control element is arranged on an outer surface of the sanding block. 
     
     
         6 . The sanding block as claimed in  claim 1 , wherein:
 the dust box is detachably fastened to the motor housing,   a first air passage opening is defined in the motor housing,   the dust box has at least one second air passage opening, and   a filter medium is supported on the dust box so that air passing through the at least one second air passage opening is caused to pass through the filter medium.   
     
     
         7 . The sanding block as claimed in  claim 1 , wherein the base plate has at least one opening configured to suction-off sanding dust. 
     
     
         8 . The sanding block as claimed in  claim 7 , wherein the base plate has an air guide element configured to suction-off sanding dust. 
     
     
         9 . The sanding block as claimed in  claim 1 , further comprising a dust suction nozzle configured to suction-off sanding dust, wherein:
 the dust suction nozzle is arranged on the outside of the sanding block, and   the dust suction nozzle is connected, by an air guide element, to the accumulator-battery-operated mechanism for suctioning-off sanding dust.   
     
     
         10 . A system comprising:
 at least one sanding block as claimed in  claim 1 , and   at least one abrasive article that is designed to be connectable to the base plate of the sanding block, wherein:   the base plate and the abrasive article respectively have at least one opening for suctioning-off sanding dust.   
     
     
         11 . The system as claimed in  claim 10 , wherein the at least one opening of the base plate and the at least one opening of the abrasive article are substantially congruent in a state in which the abrasive article has been connected the base plate of the sanding block. 
     
     
         12 . The sanding block as claimed in  claim 4 , wherein the accumulator battery and/or the dust box is configured to be received in a handle of the sanding block. 
     
     
         13 . The sanding block as claimed in  claim 8 , wherein the air guide element is in fluid communication with both the at least one opening and the accumulator-battery-operated mechanism.
