Sanding Plate of a Hand-Guided Electric Power Tool, and Electric Power Tool System

Abstract

A sanding plate for a hand-guided electric power tool includes a receiving element and a carrier element. The receiving element is configured to fasten the sanding plate to a drive shaft of the electric power tool. In particular, the receiving element is configured to connect the sanding plate to the drive shaft in a rotationally fixed manner. The carrier element is formed of at least one yielding material. The carrier element is at least partially supported by a support element that is connected to the receiving element. The ratio of the radii of a circumcircle to circumscribe the carrier element to at least one circumcircle to circumscribe the support element is in the range of from 1.3 to 2. An electric power tool system includes a sander that has an oscillating drive shaft and the sanding plate.

         2 . The sanding plate according to  claim 1 , wherein the carrier element is disposed on a side of the support element that faces away from the receiving element. 
     
     
         3 . The sanding plate according to  claim 1 , wherein the carrier element has a substantially triangular base with convex sides. 
     
     
         4 . The sanding plate according to  claim 1 , wherein the carrier element has a material hardness in the range of from 40 to 50 Shore 0 
     
     
         5 . The sanding plate according to  claim 1 , wherein the support element, in a radial direction toward triangle tips of the carrier element, has a relative extent, in respect of the carrier element, that is in a range of from 60% to 80% of a radial extent of the triangle tips. 
     
     
         6 . The sanding plate according to  claim 1 , wherein the support element, in a radial direction toward triangle sides of the carrier element, has a relative extent, in respect of the carrier element, that is greater than or equal to 90% of a radial extent of the triangle sides. 
     
     
         7 . The sanding plate according to  claim 1 , wherein the support element, in a direction perpendicular to a radial direction toward triangle tips of the carrier element, has at least one arcuate delimiting line. 
     
     
         8 . The sanding plate according to  claim 7 , wherein the support element, in the direction perpendicular to the radial direction toward the triangle tips of the carrier element, has three arcuate delimiting lines of equal curvature. 
     
     
         9 . The sanding plate according to  claim 7 , wherein the support element, in the direction perpendicular to the radial direction toward the triangle tips of the carrier element, has three arcuate delimiting lines with at least two of the three arcuate delimiting lines having differing curvatures. 
     
     
         10 . An electric power tool system, comprising:
 at least one electric power tool having a drive shaft; and   a sanding plate, including:
 a receiving element configured to fasten the sanding plate to the drive shaft, the receiving element further configured to connect the sanding plate to the drive shaft in a rotationally fixed manner; and 
 a carrier element comprised of at least one yielding material, the carrier element at least partially supported by a support element that is connected to the receiving element, the ratio of the radii of a circumcircle to circumscribe the carrier element to at least one circumcircle to circumscribe the support element being in a range of from 1.3 to 2. 
   
     
     
         11 . The electric power tool system according to  claim 10 , further comprising at least one abrasive device configured as a sanding paper. 
     
     
         12 . The sanding plate according to  claim 1 , wherein the sanding plate is configured for a sander having an oscillating drive shaft. 
     
     
         13 . The sanding plate according to  claim 1 , wherein the ratio of the radii of the circumcircle to circumscribe the carrier element to the at least one circumcircle to circumscribe the support element is in a range of from 1.4 to 1.5. 
     
     
         14 . The sanding plate according to  claim 4 , wherein the material hardness of the carrier element is in the range of from 43 to 47 Shore 0. 
     
     
         15 . The sanding plate according to  claim 5 , wherein the relative extent of the support element is in the range of from 65% to 75% of the radial extent of the triangle tips. 
     
     
         16 . The sanding plate according to  claim 6 , wherein the radial direction is toward lateral mid-points of the carrier element, and wherein the relative extent is equal to 95% of the radial extent of the triangle sides. 
     
     
         17 . The electric power tool system of  claim 10 , wherein the at least one electric power tool is configured as a sander and the drive shaft is configured as an oscillating drive shaft.
