Abstract
Abstract A retaining wall anchor system of the type primarily used to tie retaining walls to dead men. The anchor system comprises at least one wall anchor formed of a pair of spaced apart legs joined at one end to form a U-shaped portion while the other ends are attached to the retaining wall, such that the U-shaped portion extends from the wall. At least one tie rod which has one end attached to a dead man and the other end has a loop formed thereon by bending the end back toward the other end of the tie rod, around, toward and past the tie rod, so that the tie rod end extends beyond the tie rod. The tie rod is inserted between the spaced apart legs of the wall anchor, and a locking device is removably inserted through the tie rod loop such that the tie rod is attached to the wall anchor.

Claim 1
Independent Claim
241 words
A retaining wall anchor system of the type primarily intended for use in combination with a retaining wall and a dead man, said system comprising: at least one wall anchor, said wall anchor comprising a pair of spaced apart legs, each of said legs having a first end and a second end, said second ends being joined one to the other such that said legs define a substantially U-shaped portion, and said first ends being attached to the retaining wall, such that said joined second ends extend therefrom; at least one tie rod having a first end and a second end, said first end being attached to the dead man, and said second end being formed into a loop defined by bending said second end towards said first end of said tie rod, then around, toward, and past said tie rod such that said second end extends beyond said tie rod, said loop being dimensioned and configured to be insertable between said legs of said wall anchor intermediate the wall and said joined first ends of said wall anchor so that said loop is located to one side of said legs and said second end is located to the opposite side of said legs; and locking means removably insertable through said loop of said tie rod after said loop has been inserted between said legs of said wall anchor such that said tie rod may be attached to said wall anchor.
Claim 2
Dependent Claim
