Safe deposit box development history
The first stage
The history of the safe can be traced back to the Middle Ages. In medieval paintings, occasionally a wooden cabinet with gold and silver jewels is seen, which is the prototype of a modern safe. Figure 1 shows the famous French safe manufacturer replicating the wooden safe of gold and silver jewelry in the 18th century Louis. These safes are shaped like furniture, have no special locks, and are less secure. Until the early 19th century 200 years ago, with the growth of the social economy, the safe industry began to develop, and manufacturers of special locks appeared in Europe.
The material of the safe has changed from wood to various solid metals, but it is basically cast by wood splicing technology or integral. It is similar in appearance and craftsmanship to the furniture at the time, and the precision of the lock is not high.
The third phase
Figure 3 is an iron safe with a history of about 200 years. It looks like an ordinary two-door iron cabinet. The hinge is similar to the entry position of wood. The production technology is quite high. The development of safes in the United States is slightly later than in Europe, but the United States has also become a strong country in safe production. In 1857, the famous S&G (Sargent & Greenleaf) was established in the United States, and later became one of the world's most famous locksmiths and safe manufacturers.
Figure 4 is an early S & G product with a history of about 130 years. At that time, the welding technology had not been developed, and the safe was riveted with a stud, which was fierce and extremely secure.
