The right lock for the door: which is better protection against hacking

No wonder they say - "My house - my fortress", but which would not be protected apartment with alarm systems, CCTV, the chief security feature - High-quality Door and high-quality lock. More often than not we agree with the "default package" that gets us together with the door. However, only the right to lock the door you can guarantee personal security and safety of your property. Today Editorial HouseChief.ru decided to study that offers a modern market closure structures and how to keep the nerves and the property using the highest quality industry representatives castle.

Operating device door lock: the elements and mechanisms

The device of any lock, which is installed in the door there are two mechanisms - elements responsible for coupling of all parts of the physical and unlocking, as well as the secret part, which is responsible for recognition - "his" or "Alien". All locks can be divided into two types: a secret device without it. Recent species most commonly used in interior designs and not classified in the class of protection.

Hence the difference in the design of locks. For entrance groups there are a variety of specifications, characteristics and properties of which allow you to pick the lock of the design and of the quality that is needed to solve specific problems. For the owner of an apartment or office there is quite a varied choice to buy mechanical, electronic, including code, or even working on a biometric locks material. Their unlocking takes place by fingerprint.

These castles, along with integrated retina scanner attached magnetic cards. These locking mechanisms are now commonplace in offices and banking institutions, when the castle became part of the security and monitoring of employees, taking into account working hours, movement of personnel, especially on protected objects.

However, the cost of one of the castle may be 15,000 or more thousand rubles, which in the context of our review is very important. We'll show you how to operate the locks usual for us, as well as what to do if it is jammed.

Thus, the structure of a simple locking mechanism about the same. In its design, the castle has:

• larva or security mechanism;
• sliding crossbars;
• handle;
• falevye tongue;
• the trim plate.

Unlike locks on the front doorIn locking mechanism for interior variations usually have simple latch mechanism without the secret. Most modern apartments are equipped with built-in insulation displacement or locking mechanisms.

Ask a Question

"Class of secrecy allows use more protection of variations, combinations of interlocking elements intended to limit the likelihood of hacking. There is a whole series of tamper-proof models, which can be opened only with a key, or from the inside. "

This part of the castle is the most complex mechanism that locks the lock and locking structure in the case of attempts to hack or autopsy.

Kinds of door locks for entrance doors

Door locks differ not only by the method of installation, but also the principle of the secret and the locking mechanism.

What are the locks on the way of installation

Most often, pensioners do not trust modern technologies and use the old overhead, English or mortise locks. It is clear that such systems adversely affect the structure Devereaux (as they are often simple wood) And eventually such constructions can just knock the leg. This can be useful only in one case - quickly help an elderly person.

So, remember what locks can still be seen on some of the doors.

The easiest option for installation and mounting - consignment castle. The lock is mounted directly on the door leaf. Typically, the kit includes: the castle with larva and the bolt, as well as his other half - a well with a strap, More sometimes it is called the "mate", which is attached to the door frame or directly in utaplyaetsya wall. But on the very surface of the door he attached little or no recess. That is why such a lock does not break the door leaf and has practically no effect on its characteristics, in contrast to, for example, by mortise locks.

Hinged or granary locks is most often used to protect against the ingress of the simplest designs, hozpostroek, barns, toiletsIf it comes to the cottage; a mini-version is very convenient for locking mailboxes. But, alas, such locks are not effective.

built-in locks. One of the most promising to date, locking mechanisms. The thing is that these locks are mounted directly at the time of assembly of the door and, in fact, are an integral part of the door. lock mechanisms controlling the locks around the perimeter of the door structure: top, bottom, sides, above and below the castle. It is due to the large number of cross-bars open or break down this door is almost impossible.

Mortice. These types of locks are often used as a supplement to the built-in lock, and if for some reason a key or set of keys lost, often of a pair of changes is the castle. Current models of mortice locks are mounted directly to the handle and locking mechanism. This mechanism is used for the installation of both interior and input structures.

Important! Remember that overhead and mortise locks are options for tapping the left and right side of the door, depending on the location of the hinge side. In any case it is impossible to turn the lock when installing! This can lead to jamming of the working mechanisms.

Variants of locks on the principle of operation of the door lock

If embodiments with external fixation device and locks all more or less clear that the principle of operation of the lock will have to find out more. It is these nuances and features can help you quickly and efficiently to disassemble and reassemble it, and, if necessary, open it from the outside.

Thus, the type of locking device locks can be:

• cylinder (English);
• lever;
• disc;
• transom.

Features of cylinder and lever locks.

Cylinder locks them in everyday life is called English. The secret part of the castle is located in parts resembling a cylinder. The basis sekretki comprise support pins, locking the entire structure in the state "closed". The key for this lock has notches of varying lengths; their location, in fact, unique. These notches and shift pins in the "open" position.

Note! English castles are made in two types: one type with a key on the one hand; others open on both sides, but, again, it needs to use the key.

Lever locks - the locking device in which the mechanism based on a secret not pins and plate or levers.

When turning the key levers are raised to a certain level, and unlocking system works to unlock. The more such plates, the higher reliability class lock. If at least one of the plates do not reach the required height, the lock will not open. Such locks are among the most reliable.

How do disc and bolt locks

Disk, or a Finnish Castle is a bit like English, but instead of pins discs are used here. The basis of the principle of matching slots. Each disc has a hole for a key-hole slot and a special rod-balance. In the locked position, the rod does not allow discs to spin, and, accordingly, to combine all the key slot. But when inserted into the borehole native key, turning it by 90 ° holes are arranged in such a way that rod, which stops the entire system simply falls into the groove, allowing the key to make a turn and open the Castle.

Interesting fact! This secret type of locking mechanism was designed in 1907 by Emil Henriksson Finn. That is why it is often called Finnish.

Transom (Pinion) locks today one of the most unpopular. This lock device is considered to be one of the most unreliable.

Close the lock can be simple, conventional latching.

Overhead door lock apparatus

About Locks today we have already mentioned in the way that they do not affect the integrity of the door leaf. Such locks are well show themselves as complementary, combined with cutting or integrated lock.

Such locks can be used on metal and wooden structures. Very often they can be seen on fences and walling different institutions.

What are the locks depending on the class of stability to breaking

By class resistance to cracking locks are 4 types. In the Russian classification of strength classes are designated by Roman numerals, in Europe and the United States - the letters A, B, C and D. For convenience we present a table showing the characteristics of each class.

As can be seen from the table locks with first-class resistance to cracking is not recommended for exterior doors.

Important! Manufacturers locks the first and second-class strength is not even required to certify their castles on the burglar. As they say, you buy these locks at your own risk.

The task locks Class 3 - allow time patrol officers arrive at the scene of breaking. They do not guarantee complete protection against intrusion into the room. But locks protection class 4 - the most difficult for an autopsy. They are used for the protection of premises, which are stored within the work of art and material values. To this type of locks are combination locks and built for lever-type locks.

Types and structure of the locks for interior doors

Proceeding from its more mundane tasks, locks interior doors They have a simple structure. Locks with locking mechanisms are installed only in sanitary rooms or storage with a view to protection of children.

By type of construction, interior handle locks can be divided into three types:

• rotary;
• push;
• castle with handle.

Typically, in the lock bolt there is a hole for the handle (knob) and the spring tongue. When a person moves the handle or turn it, or puts down, the door is unlocked.

Note! There is also a design in the form of round-turn locks, they are called "noby". The handle pre-built locking latch, in this case the lock can be closed with one of the parties. News for toilets and showers.

In rare cases, interior doors establish full locks sekretki. This is normally constipation is common in a few owners of apartments, when for one reason or another need to limit the use of and access to one of the rooms. Most often used locks with cylinder locking mechanism.

The device lock interior door with a latch

Interior locks with latch are mortice type. Most often, this castle with a "D" -shaped handle. This lock consists of simple elements:

• front strap;
• latch and its spring;
• handle spring;
• tetrahedral holes handle;
• latch lever and the lever arm;
• a blocking device with a spring;
• bolt;
• the housing of the locking device;
• privacy mechanism;
• holes for fastening and fixing screws.

If you want to make out of this type of lock, you must first unscrew the end plate. Typically, the entire structure is mounted on a pair of screws. Then check out all the details and the tab lock. It's enough to push them inside, and then get out of the door leaf through a hole in the place of location of the pen.

Combination lock on the interior doors

Combination locks magnetic type most often used in offices. For example, in the room where limited personnel access. Code lock can be magnetic and electronic. In fact, it is more modern counterparts-lock latches.

The advantage of such locks - quiet operation and the possibility of coding and re-encoding code.

How to choose a reliable striker for the door lock

Strange as it may sound, but to buy the larvae take with you... Libra. If the head weighs less than 100 grams, the following hardware is not worth buying. This weight indicates that the mechanism is made from low-quality material.

Tip! Pay attention to the larvae weighing more than 200 grams.

In addition, pay attention to the number of pins in the mechanism (pins in the general understanding - the number of pins and plates involved in the locking mechanism of the secret). It is believed that most of the minimum number - 6. In this case, selection of options can be up to 50 thousand combinations. In models with high level of secrecy than the number of pins 6, respectively, and increasing the secrecy level.

Note! The lever locks with a key-there are no butterfly larvae. In case of loss of a key or a hack will have to change the whole castle.

There is an opinion that the lock cylinder can supposedly bring down the hammer with a chisel. From such a barbaric hacking has its own protection: installation of special steel spring, which will provide additional strength to the larva.
