Handheld power tool

Abstract

The present invention relates to a handheld power tool including: a main housing, a rear handle mounted on the main housing and a handle connected to the main housing. A base portion of the main housing has a buffing member in the basal plane. The handle comprises two oppositely disposed side handle members and a front handle joined between the front end portions of the two oppositely disposed side handle members. The two oppositely disposed side handle members tilt (ie are non-parallel) with respect to the basal plane. The present invention has the advantage that during buffing of a workpiece, the operator's wrists need bend to only a small degree to accommodate the non-parallel disposition of the buffing member leading to labour efficiency and reduced wrist tiredness.

 a main housing having a base portion, wherein the base portion has a buffing member in the basal plane;    a rear handle mounted on the main housing;    a handle connected to the main housing, wherein the handle comprises two oppositely disposed side handle members each having a front end portion and a rear end portion, wherein the handle further comprises a rear connecting member joining the rear end portions of the two oppositely disposed side handle members and having side end portions, wherein the rear connecting member is cooperatively connected to the rear handle; and    a front handle member connected between the front end portions of the two oppositely disposed side handle members, wherein the front handle member has side end portions, wherein the two oppositely disposed side handle members are tilted with respect to the basal plane.    
   
   
       2 . The handheld power tool according to  claim 1 , wherein the two oppositely disposed side handle members each have at least one upwardly arched arcuate portion.  
   
   
       3 . The handheld power tool according to  claim 2 , wherein the front handle member has an upwardly arched arcuate portion.  
   
   
       4 . The handheld power tool according to  claim 1 , wherein the front end portions of the two oppositely disposed side handle members are smoothly interconnected respectively with the side end portions of the front handle member and the rear end portion of the two oppositely disposed side handles are smoothly interconnected respectively with the side end portions of the rear connecting member.  
   
   
       5 . The handheld power tool according to  claim 1 , wherein the handle further comprises a front connecting member having two end portions, the two end portions of the front connecting member being respectively secured to the two oppositely disposed side handle members, wherein the front connecting member bears against the main housing.  
   
   
       6 . The handheld power tool according to  claim 1 , wherein the two oppositely disposed side handle members are tilted upwardly with respect to the basal plane from rear to front.  
   
   
       7 . A handheld power tool for buffing a workpiece comprising: 
 a main housing having a buffing member in a basal plane, wherein the main housing houses a mechanism operable to drive the buffing member;    a rear handle mounted rearwardly on the main housing;    an annular handle mounted around the main housing, wherein the annular handle adopts a wavy profile;    two oppositely disposed side handle members each having a front end and a rear end and at least one upwardly arched arcuate portion; and    a front handle member connected between the front ends of the two oppositely disposed side handle members, wherein the annular handle further comprises a rear connecting member joining the rear end portions of the two oppositely disposed side handle members wherein the rear connecting member cooperates with the rear handle.    
   
   
       8 . The handheld power tool according to  claim 7 , wherein the annular handle adopts a substantially chair-like configuration relative to the basal plane.  
   
   
       9 . The handheld power tool according to  claim 8 , wherein the chair-like configuration is rearward facing.  
   
   
       10 . The handheld power tool according to  claim 9 , wherein the two oppositely disposed side handle members adopt a substantially S-shaped profile.  
   
   
       11 . The handheld power tool according to  claim 9 , wherein the front handle member has an upwardly arched arcuate portion.  
   
   
       12 . The handheld power tool according to  claim 11 , wherein the front handle member adopts an inverted substantially U-shaped profile.  
   
   
       13 . The handheld power tool according to  claim 7 , wherein the annular handle further comprises a front connecting member having two end portions, the two end portions of the front connecting member being respectively secured to the two oppositely disposed side handle members, wherein the front connecting member is mounted against the main housing.  
   
   
       14 . The handheld power tool according to  claim 13 , wherein the front connecting member is respectively secured to the two oppositely disposed side handle members in the plane of the substantially chair-like configuration.  
   
   
       15 . The handheld power tool according to  claim 13 , wherein the front connecting member adopts a substantially U-shaped profile.  
   
   
       16 . The handheld power tool according to  claim 13 , wherein the front connecting member has a cutaway portion which permits the front connecting member to be seated against the main housing.  
   
   
       17 . The handheld power tool according to  claim 15 , wherein the front connecting member adopts a substantially X-shaped profile.
