Protective element for an electric power tool

Abstract

A protective element, in particular a cover, for the guard of a disk-shaped tool of an electric power tool, in particular an angle grinder. The protective element has a protective element body that is reversibly attached to the guard in an installed position by clamping the guard between attachment elements and a leaf spring of the protective element body. The invention also relates to a manufacturing method for the protective element and an electric power tool having this protective element.

What is claimed is: 
     
         1 . A protective element for a guard of a disk-shaped tool of an electric power tool, in particular an angle grinder, the protective element being configured to be captively and reversibly connectable to the guard and to at least partially cover the tool, the protective element comprising:
 a protective element body;   a first end and a second end opposite the first end;   at least one attachment element mounted on the first end and is configured to be reversibly connectable to a guard edge of the guard during installation of the protective element on the guard; and   a receiving device to receive a leaf spring, the receiving device being arranged on the second end,   wherein the leaf spring is arranged in the receiving device and is configured such that the leaf spring is tensioned in an installed position of the protective element on the guard and the guard is clamped between the leaf spring and the at least one attachment element,   wherein the receiving device includes two opposite regions with respect to a central axis of the protective element body, wherein each of the two opposite regions comprises:
 a clamping edge, wherein the leaf spring rests against the clamping edge in the receiving device when the protective element is installed; 
 a contact section, wherein a distance between the two contact sections is less than a length of the leaf spring; and 
 a transition edge that includes a transition from the receiving device to an inner circumference of the protective element body or to an inner circumference of an outer wall of the protective element body. 
   
     
     
         2 . The protective element according to  claim 1 , wherein the leaf spring is brought into a first position in which the leaf spring has little tension or no tension, in which the protective element is removed and is spaced apart from the guard, and is brought into the installed position in which the protective element is captively and reversibly clamped to the guard via a clamping force of the leaf spring. 
     
     
         3 . The protective element according to  claim 1 , wherein the protective element body has a rear wall and, opposite hereto, a wall, wherein a free space is defined below the wall in a direction of the rear wall, and wherein the free space is configured to permit the installation of the tool via a tilting. 
     
     
         4 . The protective element according to  claim 1 , wherein the protective element body has an extension, wherein the extension is configured to surround the guard via which the installed protective element is held immovably. 
     
     
         5 . The protective element according to  claim 3 , wherein the wall is arranged at an angle or an angle of 3°, to the rear wall. 
     
     
         6 . The protective element according to  claim 1 , wherein the attachment element permits an interlocking and/or frictional connection to the guard and or is hooklike in design. 
     
     
         7 . The protective element according to  claim 1 , wherein the leaf spring is metallic, and, or, contains an austenitic material, in particular nickel-chromium steel 1.4310. 
     
     
         8 . The protective element according to  claim 1 , wherein the deflection of the leaf spring in the installed position is accomplished in such a way that its center point is displaced radially outward toward an outer wall of the protective element body with respect to the tool axis. 
     
     
         9 . The protective element according to  claim 1 , wherein the material of the protective element is chosen from the group of thermoplastics or polyamides or glass-fiber reinforced thermoplastics. 
     
     
         10 . The protective element according to  claim 1 , wherein the protective element body is monolithic in design. 
     
     
         11 . The protective element according to  claim 1 , wherein the leaf spring is an elongated part with a length that is several times greater than the maximum height of the component, in particular with a length between 40 and 100 mm, preferably between 60 and 80 mm. 
     
     
         12 . The protective element according to  claim 11 , wherein the leaf spring has a deflection, or a deflection of between 2 mm and 6 mm, or has a deflection of 4.1 mm, when the protective element is installed on a guard. 
     
     
         13 . An electric power tool, in particular angle grinder, comprising a protective element according to  claim 1 . 
     
     
         14 . A method for producing the protective element according to  claim 1 , the method comprising:
 creating the protective element body by an injection molding method; and   inserting the leaf spring into the receiving device of the protective element body.   
     
     
         15 . The protective element according to  claim 1 , wherein the protective element is a cover.
