Attachment device

Abstract

A system including an attachment device having a generally flat plate having a securement structure, and two hooks movably coupled to the plate. A base end of each hook is spaced apart by a natural number multiple of a hook spacing distance, and the hook spacing distance is between about 1¾ inches and about 2¼ inches, or is between about 2¾ inches and about 3¼ inches.

What is claimed is: 
     
         1 . A system comprising an attachment device including:
 a generally triangular, generally flat plate having first, second and third corners, the plate further having a securement opening positioned adjacent to the first corner;   a first hook movably coupled to the plate adjacent to the second corner; and   a second hook movably coupled to the plate adjacent to the third corner, wherein the first and second hooks are each aligned in a plane oriented generally perpendicular to a plane of the generally flat plate.   
     
     
         2 . The system of  claim 1  wherein the plate includes a first and second hook openings, wherein the first hook is directly received through the first hook opening and wherein the second hook is directly received through the second hook opening. 
     
     
         3 . The system of  claim 2  wherein the securement opening is larger than the first hook opening and larger than the second hook opening. 
     
     
         4 . The system of  claim 2  wherein the first and second hooks are each made of a generally cylindrical material having a radius generally corresponding to a radius of the associated hook opening such that each hook is closely received in the associated hook opening and retained in the alignment wherein each hook is aligned in a plane oriented generally perpendicular to the plane of the generally flat plate. 
     
     
         5 . The system of  claim 1  wherein the first and second hooks are each generally “S” shaped. 
     
     
         6 . The system of  claim 1  further comprising a third hook movably coupled to said plate and generally aligned with the first hook and the second hook. 
     
     
         7 . The system of  claim 1  wherein a base end of the first hook and a base end of the second hook are spaced apart by a multiple of a hook spacing distance, and wherein the hook spacing distance is between about 1¾ inches and about 2¼ inches, or between about 2¾ inches and about 3¼ inches. 
     
     
         8 . The system of  claim 1  wherein a base end of the first hook and a base end of the second hook are spaced apart by a multiple of a hook spacing distance, and wherein the system further comprises a generally flat, planar piece of material having regularly spaced openings, wherein the openings of said piece of material are spaced apart, on center, by said hook spacing distance. 
     
     
         9 . The system of  claim 8  wherein each hook extends through one of said openings of said piece of material to secure said attachment device to said piece of material. 
     
     
         10 . The system of  claim 9  wherein the piece of material is made of expanded metal. 
     
     
         11 . The system of  claim 1  wherein said plate is generally shaped as non-equilateral isosceles triangle in front view, and wherein said securement opening is positioned adjacent to a vertex of said triangle, and wherein the first and second hooks are both positioned adjacent to a base edge of said triangle. 
     
     
         12 . The system of  claim 1  wherein said plate is made of metal and has a thickness of less than about ¼ inch. 
     
     
         13 . The system of  claim 1  wherein each corner is a rounded corner. 
     
     
         14 . The system of  claim 1  wherein the plate is a single piece of flat material and lacks any flanges or protrusions coupled thereto or extending therefrom, besides any hooks which may be coupled to the piece of material or extend from the piece of material. 
     
     
         15 . A system comprising an attachment device including:
 a generally triangular flat plate having a securement structure;   a first hook movably coupled to the plate; and   a second hook movably coupled to the plate, wherein a base end the first hook and a base end of the second hook are spaced apart by a natural number multiple of a hook spacing distance, wherein the hook spacing distance is between about 1¾ inches and about 2¼ inches, or is between about 2¾ inches and about 3¼ inches.   
     
     
         16 . The system of  claim 15  wherein the and second hooks are each aligned in a plane oriented generally perpendicular to a plane of the generally flat plate. 
     
     
         17 . The system of  claim 15  wherein the system further comprises a generally flat, planar piece of material having regularly spaced openings, wherein the openings of said piece of material are spaced apart, on center, by said hook spacing distance. 
     
     
         18 . The system of  claim 15  wherein the hook spacing distance is about 2 inches or about 3 inches. 
     
     
         19 . A system comprising:
 an attachment device including a generally flat plate having a securement structure, a first hook movably coupled to the plate and a second hook movably coupled to the plate, wherein a base end of the first hook and a base end of the second hook are spaced apart by a natural number multiple of a hook spacing distance; and   a piece of material having a plurality of openings, wherein the openings of said piece of material are spaced apart, on center, by the hook spacing distance.   
     
     
         20 . The system of  claim 19  wherein the hook spacing distance is between about 1¾ inches and about 2¼ inches, or between about 2¾ inches and about 3¼ inches.
