All About Handcuffs

Handcuffs: metal rings connected by a chain, put on the hands of criminals, prisoners (explanatory dictionary).

For representatives of security and law enforcement agencies, handcuffs are an integral attribute. The competent use of special equipment makes it possible to limit the physical capabilities of the detainee. Two metal bracelets connected by welded chain links have a locking part that allows you to snap “bracelets” without a key.

Handcuffs first appeared relatively long ago, almost immediately after the invention of iron. They were very different from those that can be seen today at private security guards. Two pieces of iron connected by a chain did not have a shutter; they were fastened on the wrists of a person by heating a pin inserted into the eyes of a bracelet on fire. Naturally, there weren’t any keys; they were removed thanks to a chisel and a hammer.

1912 was a turning point. Instead of heavy shackles, Peerless engineers invented a design with a douche that turned through and through. Thus, the handcuffs could be adjusted to the size of the brushes of a particular person. In addition, a ratchet mechanism was used in the handcuffs, the principle of which is based on the fact that the upper handle of the handcuffs could freely rotate in only one direction, and vice versa, only if the ratchet holds the key.

At the moment, the size of the handcuffs allows them to be used on an arbitrarily small hand (we are talking about adults), because in the extreme position, the arms are compressed to an oval with sides of 5 and 4.5 cm, but they can also be snapped onto the wrists of a sufficiently large size or even on the ankle. When worn on a belt, a case is used for carrying handcuffs.

The BR-S, BR-C2, BKS-1, and BOS handcuffs are included in the list of special equipment used in private security activities.

Short description

BR-S
two-link handcuffs (complete with one key, locked in position)

BR-C2
two-link handcuffs (with a lock of increased complexity, complete with two keys, are fixed in the set position). The key is non-standard - flat, the flag is forked.
The BRS-2 handcuffs are available in two versions, burnished and nickel-plated, two-link complete with two keys, with a lock of increased complexity, with fixation in a given position. certificate of conformity No. ROSS RU.СЗ09.Н00846; No. 0101351, Issued by: NPO Technika, Ministry of Internal Affairs of Russia. Weight: 380g.
Of the advantages, the latch is divided into two parts and there is a jumper in the lock between them, which makes it impossible to squeeze both latches with something simple like a paper clip. The disadvantage is that the keyhole comes out on both sides, which reduces the resistance to tampering.

BCS-1

special escort handcuffs, available in three versions:
- BKS-1 "Tenderness-1" - special escort handcuffs with a connecting chain. They remain operational after applying a tensile load of at least 1,500 N for 30 seconds. Semi-rigid swivel linkage. Auto snap.
The transverse breaking force of the engagement of the rotary bracket is not less than 2500 N. The number of operations is not less than 5,000 cycles.
The ratchet mechanism of the products is made with a negative angle of engagement of the teeth (with undercutting), which ensures the operation according to the "shark tooth" principle. The increased angle of the back plane of the tooth glide ensures easier snapping-in, increases mechanical gearing strength and wear resistance.
- BKS-1 "Prikol" - handcuffs with stationary fastening
- BKS-1 "Bouquet" - escort handcuffs for 5 people

Biofeedback
special operational handcuffs (with a rigid system for attaching bracelets to each other)


Handcuff operation and storage conditions:
Operate at temperatures from -30 to + 40 ° C; the product must be stored in a package in an enclosed space with an air temperature of +5 C to +40 C and a relative humidity of not more than 80%
Periodic cleaning and lubrication of handcuffs is recommended according to the manufacturer's instructions;
It is recommended to store the product in dry warehouse
Avoid joint storage with acids, alkalis and other substances that are aggressive towards metals;
During operation, the degree of structural rigidity and the reliability of fixing each type of handcuffs, determined by the type of locks and connecting devices between the bracelets, should be taken into account.

There is also a very rare handcuff with a timer; I personally saw his work in action. we called him a "boa constrictor." you put him on your arm or leg for 30 minutes and tell the detainee that he “voluntarily” during this time would run to the first police station or where necessary. If during this time he does not have time to reach his destination, then the spring inside the handcuff begins to straighten, squeezes the limb accompanied by strong pain and can break it !!! The handcuff worked flawlessly !!!
