Wall Fastener with Knife Blade and a String

Abstract

A wall fastener includes a nut having a major planar structure having a hole for receiving a screw, the major planar structure having a first end with two staggered knife edges on opposite sides of the major planar structure and a second end; and a string, wherein the string is detachably connected to the major planar structure.

1 . A nut for a wall fastener comprising:
 a planar structure having a main hole for receiving a screw, the planar structure having a knife edge at the first end and a second end; and   a string detachably connected to the planar structure in an area adjacent to the main hole.   
     
     
         2 . The nut for a wall fastener of  claim 1 , wherein the nut is made of a metal or a metal alloy. 
     
     
         3 . The nut for a wall fastener of  claim 1 , wherein the nut is made of steel, tempered steel, stainless steel, titanium, brass, bronze, monel, and/or silicon bronze. 
     
     
         4 . The nut for a wall fastener of  claim 1 , wherein the major planar structure is about 11 mm wide and about 25 mm long. 
     
     
         5 . The nut for a wall fastener of  claim 1 , wherein the string is made from plastic and/or a natural fiber. 
     
     
         6 . The nut for a wall fastener of  claim 1 , wherein the planar structure includes two staggered knife edges. 
     
     
         7 . The nut for a wall fastener of  claim 1 , wherein the planar structure includes two string holes through which a loop of string extends, and the two holes are on opposite sides of the main hole. 
     
     
         8 . The nut for a wall fastener of  claim 1 , wherein the planar structure includes a flange surrounding the main hole and a smaller hole extending through the flange, and the string is fastened through the smaller hole. 
     
     
         9 . The nut for a wall fastener of  claim 1 , wherein the planar structure includes a notch at the second end. 
     
     
         10 . The nut for a wall fastener of  claim 1 , wherein the planar structure includes two knife edges arranged symmetrically on the planar structure. 
     
     
         11 . A method of securing a wall fastener to a wall, the method comprising:
 providing a nut having a planar structure with a main hole for receiving a screw, the planar structure having a first end with a knife edge and a second end; and a string, wherein the string is detachably connected to the planar structure in an area adjacent to the main hole;   driving the nut through the wall so that the nut passes through to a back side of the wall;   applying tension to the string so as to draw the nut parallel to the back side of the wall; and   inserting a screw through the wall into the main hole of the planar structure.   
     
     
         12 . The method of  claim 10 , further comprising making a small hole in the wall prior to driving the nut through the wall and driving the nut through the small hole in the wall, wherein the nut enlargens the small hole as it is being driven through the wall by creating slots on opposite sides of the small hole. 
     
     
         13 . A nut for a wall fastener comprising:
 a major planar structure having a hole for receiving a screw, the major planar structure having a first end with two staggered knife edges on opposite sides of the major planar structure and a second end having a notch; and   a string forming a loop, wherein the string loop is detachably connected to the major planar structure via two holes on the major planar structure, wherein the two holes are separated by the hole for receiving the screw.   
     
     
         14 . The nut for a wall fastener of  claim 13 , wherein is made of a metal or metal alloy. 
     
     
         15 . The nut for a wall fastener of  claim 13 , wherein the nut is made of steel, tempered steel, stainless steel, titanium, brass, bronze, monel, and/or silicon bronze. 
     
     
         16 . The nut for a wall fastener of  claim 13 , wherein the major planar structure is about 11 mm wide and about 25 mm long. 
     
     
         17 . The nut for a wall fastener of  claim 13 , wherein the major planar structure of the wall fastener has a width to length ratio of about 1:2. 
     
     
         18 . The nut for a wall fastener of  claim 13 , wherein the string is made from plastic and/or a natural fiber.
