How to disassemble door lock interroom door

The mandatory door to the door is the handle, as it is quite difficult to open and move the sash without it. If we are talking about the apartment, then as shut-off mechanisms are the usual handles with latches - this is enough to ensure a dense fit of the sash to the frame. However, if the inhabitant of the room wants to prevent access to the room not only when he himself is there, but then, when there is no, without a full-fledged castle, can not do.

Classification of locks for interior door

In private dwellings, complex mechanisms are rarely used, because in this simply there is no need. However, in office buildings, the need to close each room is quite explained. At the same time, the doors to the office are a simple interior design, made, as a rule, in the budget version, that is, not differing in thickness and strength. Accordingly, establish a rather complicated and heavy mechanism on them most often is simply impossible.

Castle in such cases - a compromise between the material of the door canvase and fittings.

According to the type of locking, they can be divided into two groups.

• Suwald - reliable, but having a fair weight device. The door is fixed by locking the Suwalds - the more they are more, the harder it is to open the lock. For interior options, it is rarely used because of the large mass. The photo shows a sample.
• The cylinder - got its name due to the shaped of the core - as a cylinder. Locking is carried out with the help of six busings, that is, the castle itself is resistant to opening attempts. However, the mechanical strength is small. If the device is installed on the input doors, then it should be strengthened with solid linings. For interior design, the cylinder lock is suitable as it is impossible - it is easily mounted, immeasured and has a small mass.

Mounted locking mechanism in several ways.

• Curling is the most popular way. The device is crashed into the door cloth, which provides limited access to it. Release both options with a handle and without it. The photo shows mortise fittings for interior door.
• The invoice is to install it requires an amplification of the door leaf, and therefore it is practically not used for interior blocks.
• Attachment - closes by selling through special hinges. Since the device is fully accessible, its reliability is very relative. Inside the building, it is installed in storage rooms and small warehouses, the value of the content of which is small.

How to disassemble the castle with a handle

It is the most simple arranged door mechanism, so you can disassemble it with your own hands.

1. The lining panel with a flat end is raised. If the lock is assumed to be reused, care should be taken: to simply improve the panel on the entire perimeter so as not to damage when removing.
2. A device with a handle, as a rule, has a stopper that locks its position. It is necessary to hold a screwdriver or other subject with the subtle end of the stopper, and the other hand to shoot accessories.
3. Two screws connecting the external and internal fragments of the mechanism are unscrewed. Then the handle is removed from the outside of the door, and the castle core is removed.

In order to remove the mechanism with the Nob, usually use the same slot that provides emergency opening. In the photo - a locking device with the Nob.

1. On the front of the lining in most models a hole is formed. When you click on it with a sharp end or a special key, a spring-end retainer is blocked. The handle thus ceases to be held and easily removed.
2. Then the decorative lining is raised and removed. It provides access to the fastening screws.
3. The screws are unscrewed and the device is removed.
4. If the mechanism fails, the core is not removed, then, most likely, it is caused by blocking the secret mechanism. To remove the device, you must simulate closing. For this, the key is inserted into the keyhole and turns on 10-15 degrees. This is enough to remove the lock and remove the mechanism.

How to disassemble the castle without a handle

The sequence of actions depends on the type of shut-off mechanism - the suvalde or cylinder. There are models that the possibility of disassembly do not intend. They can be distinguished in the absence of screwdriver in the casing. In the latter case, the device can only change the device, as it will require the disassembly of the door leaf.

• Suwald mechanism is the most easy to maintain. With the help of screwdriver, screws that hold the mechanism on the end side of the door are unscrewed. Since no additional blocks do not assume the device, then you should push the housing with a screwdriver through the keyhole. The connection is quite dense, but when a large enough of the device is released, you can pick it up and remove it.

• Cylinder - In order to disassemble the same actions. The fastening screw is removed from the end of the case, and the core is pushed from one and the other side until it is possible to remove it. If the action is difficult, the position of the larva should be adjusted. To do this, you need to insert the key into the keyhole and turn it until it is set to such a position in which the larva is easily removed.
