Title: Safety device of rotary press
Inventor: RUUDEI YUNKUHANSU
IPC: B41F33/00
Filed: 1994-02-04
Abstract: PURPOSE: To optimize a safety device without disturbing riding on a working base by incorporating a pivotable safety protective arm which yields obliquely upwardly in response to a contact force applied from below. CONSTITUTION: When a worker rises on a ladder 8, his shoulder is brought into contact with a pivotable protective arm 11. When the worker further rises, the arm 11 is then deflected obliquely upward by the shoulder and then his hip, and hence the worker can ride on a working base 10 without disturbing. When the worker is not brought into contact with the arm 11, the arm 11 is automatically returned to a protective position. Accordingly, it is impossible that the arm 11 is opened without his intention. The worker on the base 10 is protected by the arm 11 turned and returned to the protective position by its own weight. When the worker desires to release from the base 10, he comes to the position of the arm 11 and obliquely inclines it. Then, since the arm 11 is moved in a plane inclined about 45 degrees at the maximum, the worker is not necessary to retract slightly from the arm 11.
