Abstract

A guide chute for dropping articles has four shock absorbable members arranged in a vertical direction at regular intervals, and four ropes for connecting the shock absorbable members to one another. Each of the shock absorbable members is composed of a frame member, a plurality of elastic trapezoidal plates which are secured to the frame member, and coil springs for retaining the trapezoidal plates in a throttled condition. The width of each of the trapezoidal plates is increased towards its free tip end. The free tip end of each of each of the trapezoidal plates extends downward and toward the axial center of the frame member and is overlapped with adjacent free tip ends of adjacent trapezoidal plates to form a conic cylindrical body by virtue of the coil springs. And the free tip ends of the trapezoidal plates define an opening of a diameter smaller than that of articles to be dropped. When the dropping articles drop, they enlarge the opening of each of the shock absorbing members. At this time, the dropping articles receive friction force from the trapezoidal plates and elastic reaction force of the coil springs and accordingly dropping energy of the dropping articles is reduced.

Claims1

Dependent claims

A guide chute for dropping articles comprising:

a plurality of shock absorbable members arranged vertically at intervals;
and
deformably connecting members for connecting said plurality of shock absorbable members vertically;
each of said plurality of shock absorbable members being composed of a circumferential frame member secured to said connecting members, and a plurality of elastic trapezoidal plate pieces each having a width gradually increasing toward its free tip end, which are secured to said frame member;
said plurality of elastic trapezoidal plate pieces extending downward from a plurality of circumferentially arranged portions of said frame member towards an axial center of said frame member;
said plurality of elastic trapezoidal plate pieces being assembled and retained by spring members so that said free tip ends of said plurality of elastic trapezoidal plate pieces are overlapped with each other to form a conic cylindrical body of which the diameter is decreased downward and the lower end defines an opening of a diameter smaller than that of dropping articles whereby the dropping energy of the dropping articles is reduced by friction resistance and elastic reaction force received when said opening of said conic cylindrical body is enlarged due to the drop of the dropping articles.
