Magnetic corner guard

Abstract

A wall trimming (also called a corner guard) is provided for protecting a corner of a wall. The corner guard is an elongated body in an L-shape having recessed portions within inner surface facing the wall. The recessed portions hold magnets configured to hold the corner guard using magnetic attraction to a magnetic material fixed inside the wall, which may be a metal corner bead or magnetic inserts, for example. The recessed portions may be dimensioned according to the dimensions of the insert magnets, such that magnets are flush with the inner surface of the corner guard. The corner guard may have three layers with the recessed portions cut out of the inner layer, a decorative pattern cut into the outer layer, and the middle layer providing a backstop to prevent the recessed portions and magnets from being visible through the decorative pattern cut into the outer layer.

         8 . The wall trimming element of  claim 1 , wherein the corner guard member includes a recessed portion in the inner surface, and the magnet is affixed within the recessed portion. 
     
     
         9 . The wall trimming element of  claim 8 , wherein a depth of the recessed portion in the inner surface is sized according to dimensions of the magnet such that when the magnet is affixed within the recessed portion the magnet does not extend beyond a plane of the inner surface that is configured to abut a wall surface. 
     
     
         10 . The wall trimming element of  claim 1 , wherein the elongated body includes a plurality of layers, each layer having respective planar portions that are joined at a wall corner, the plurality of layers includes an outer layer and an inner layer, the outer layer facing away from the wall corner, and the inner layer facing toward the wall corner. 
     
     
         11 . The wall trimming element of  claim 10 , wherein the inner layer includes a recessed portion in the inner surface, and the magnet is affixed within the recessed portion. 
     
     
         12 . The wall trimming element of  claim 1 , wherein the elongated body has a length of between 15 inches and 48 inches. 
     
     
         13 . The wall trimming element of  claim 10 , wherein the plurality of layers includes a middle layer configured to prevent a recesses cut into the inner layer from being visible through a cut in the outer layer. 
     
     
         14 . The wall trimming element of  claim 10 , wherein the outer layer is fixed to a next layer of the plurality of layers using an adhesive. 
     
     
         15 . The wall trimming element of  claim 1 , wherein, when positioned at the angled section of the wall, the wall trimming element is configured to provide an impression of being permanently fixed to the angled section of the wall. 
     
     
         16 . A wall trimming system for positioning a corner guard at an angled section of a wall, the wall trimming system comprising:
 a magnetic material fixed within a wall and arranged proximate with an angled section of the wall, wherein the magnetic material is a metal corner bead, a metal lath, or a magnetic insert;   a corner guard member having an elongated body including planar portions joined at a wall corner, the planar portions respectively being configured to have an inner surface and an outer surface, the inner surface being configured to abut a wall surface of a wall, and   a magnet affixed to the corner guard member, the magnet being arranged such that, when the corner guard member is positioned at the angled section of the wall, the magnet will be proximate to the magnetic material fixed within the wall and inducing a magnetic attraction of 10 pounds or greater.   
     
     
         17 .
