Shock-absorbing tie brace

Abstract

A shock-absorbing tie brace has a central member and an outer frame. The central member has two ends and multiple neck portions. Each neck portion has a dimension of cross section smaller than that of the ends to form multiple enlarged portions beside the neck portions on the central member. The outer frame is mounted around and encloses the central member. Accordingly, the shock-absorbing tie brace has an excellent capability for bearing buckling load and is not easily bent or buckled.
