Guard fence for use in drop test

Abstract

A guard fence for use in a drop test includes a frame defining a test area, four support legs respectively connected to the frame for supporting the frame, and four buffer curtains made of elastic materials and respectively disposed between two adjacent support legs for encircling the test area. As a result, when a drop test is conducted, the buffer curtains can effectively prevent the test sample from an undesired impact.

1 . A guard fence for use in a drop test, the guard fence comprising:
 a frame defining a test area;   four support legs respectively connected to the frame for supporting the frame; and   four buffer curtains made of elastic materials and respectively disposed between two adjacent said support legs for encircling the test area.   
   
   
       2 . The guard fence as claimed in  claim 1 , wherein the frame includes four transverse bars each having two ends respectively connected to two adjacent said support legs. 
   
   
       3 . The guard fence as claimed in  claim 2 , wherein the four buffer curtains are respectively connected to and suspended downwardly from the four transverse bars. 
   
   
       4 . The guard fence as claimed in  claim 2 , wherein the two ends of each transverse bar is hingedly connected to two adjacent said support legs. 
   
   
       5 . The guard fence as claimed in  claim 4 , wherein two opposite ones of the transverse bars each include two sections, each of which has an end hingedly connected to one of two adjacent said support legs, and the other end hingedly connected to that of the other section. 
   
   
       6 . The guard fence as claimed in  claim 5 , wherein two of the buffer curtains are respectively connected to the two opposite ones of the transverse bars and each have a crevice corresponding to a position where the two sections of one of the two opposite ones of the transverse bars are hingedly connected with each other. 
   
   
       7 . The guard fence as claimed in  claim 1 , further comprising four wheels respectively rotatably mounted to bottom ends of said support legs.
