How to disassemble the door handle of an interior door?

Nowadays, almost any interior door is equipped with such a thing as a doorknob. Moreover, we are not talking about an ordinary handle, for example, a round one, which you can simply grab, but about a mechanism that allows you to open and close the door and, if necessary, keep it in a closed position, despite the efforts made to open it. Such a mechanism is, for example, a latch with a latch. As the operation progresses, the door hardware wears out, and any handle simply breaks.

Today we will talk about how to disassemble and dismantle it.

First, let's talk about the designs of door handles and their features.

• The first category we will look at is stationary models... These are the most common solutions for interior doors. Such fittings are practically not used now. Is that on the doors installed back in the days of the Soviet Union, which have not been modernized since then. Yes, and in residential premises, it is usually not used. Outwardly looks like a bracket. There are two types of this model. The difference between them is that they can be one-sided or end-to-end.

Such a handle can be removed very easily - just unscrew the bolts that hold this structure. Such accessories can literally be called a penny, since they have a minimal price. And it is pointless to repair it, because it does not understand.

• The next option is push design... Such a structural decision will be a little more complicated. The handle is a lever-type product: thanks to the axis, the working elements are tied to the lock mechanism. Some variants of this type are additionally equipped with a retainer that locks the obturator.

• Another construct that should be mentioned is swivel model... It has a lot of differences from the aforementioned options, which lie in the form and design features. The general operating principle is the same as for other models.
• The next version of the considered accessories for the interior door - rosette handle... Such handles have a round shape and, depending on the design, can be disassembled according to different algorithms. They also differ in the method of fixing the decorative element. The spherical shape is very easy to use. Such models are also called knobs.

In general, as you can see, there are a large number of door handles for interior doors. Each type has its own advantages and disadvantages, at the same time, the algorithm for disassembling them will be approximately the same.

To disassemble the door handle, you will need to have a certain tool on hand. Regardless of its type, there may be some hidden elements and parts in it that cannot always be pulled out using ordinary devices.

For this reason, the following list of tools should be handy:

• hammer;
• screwdriver;
• drill and a set of drills with a crown;
• pencil;
• awl;
• square.

Dismantling the door handle is quite simple with the aforementioned tools, as well as a little knowledge of the theoretical plan for the structure of this mechanism.

To do this, you need to follow these steps.

• Support and secure the door well so that it is stationary.
• Now you need to pry off the decorative type flange and pull it out a little. Under it are fasteners that should be unscrewed.
• On the mentioned flange of the pressure part there is a special pin, which is a locking and spring-loaded. It should be pressed in using a screwdriver. In rotary versions, it is usually located in the body. To get there, you must insert a key or an awl. If it was not possible to feel it, then the flange should be rotated until it touches the pin.

• Now you should press the pin and at the same moment pull back the handle structure.
• Now we unscrew the fastener bolts.
• We separate the inner part of the element from the outer one, take out the handle and decorative flange.
• If there is a need to remove the latch for replacement or repair, then you should unscrew the screws that fix it to the side of the door block, then remove the bar, and then the mechanism itself.

When installing fittings in a different position, it is better not to disassemble it for parts. It is easily attached to the door structure, but in the reverse order.

Now let's talk directly about the disassembly of each category of handles.

• Let's start with the stationary, which does not have a push headset, and is also not equipped with a mortise-type lock. In order to unscrew such a handle, you will need a Phillips or flathead screwdriver. Alternatively, you can use a screwdriver. Dismantling must begin by loosening the screws that secure the mechanism.

It should be noted that the mount can be single or double-sided, respectively, the structure can be disassembled in different ways, which means that you need to take care of this in advance. When all the bolts have been unscrewed, it is necessary to carefully remove the handle from the door leaf using a flat-tipped screwdriver. In place of the old handle, another mechanism is installed, or the same design, but with new spare parts.

• If lead talking about disassembling a round handle with a rosette, then it is required to clarify that the word "socket" is usually understood as a mechanism that allows the lock to be locked using a small key on one side, which is not used on the other side. There is a special lamb on the second side. In this situation, the disassembly of the mechanism will be carried out according to the following algorithm:
  1. first, the screws that hold the trims that perform the decorative function on both sides are loosened;
  2. the screws connecting the mechanism on both sides are unscrewed;
  3. the handle structure is pulled out and the rest of it is removed;
  4. the locking mechanism is pulled out.

• Now let's talk about disassembling the round knob handle... To dismantle this element from the door leaf, the following actions are usually performed.
  1. Unscrew the fastening bolts on one side of the door.
  2. The mechanism is dismantled through special holes.
  3. The disassembly of the additional counter-type bar is carried out. To dismantle this element, you just need to pull it in your direction.

• Push options... Usually they are used instead of rotary solutions. This is due to the fact that they are durable and very easy to use and repair. Disassembly is carried out as follows:
  1. first, the screws are unscrewed that hold the decorative canvas of the overhead type, which performs the function of a stuck;
  2. after this, the overhead canvases located on both sides are carefully removed;
  3. the bolts of the fasteners are unscrewed and the structural elements of a round shape located on both sides of the door leaf are pulled out;
  4. all that remains is to open the strike plate and the lock itself, and then pull them out of the fittings grooves.

Often, door handle repairs are carried out in the following situations:

• the handle is sticky and difficult to turn;
• the handle does not return to its normal position after being pressed;
• the handle falls out, and the base is not damaged;
• the tongue does not move when pressed.

As a rule, the cause of these malfunctions is wear and tear, as well as erasure of parts due to constant use. For this reason, it is necessary to periodically lubricate the spare parts of the lock and mechanism, to clean everything from dirt. When lubricated, the product is scrolled so that the liquid evenly falls on all elements and parts. If the handle loosened, then the fasteners should be corrected and tightened.

Sometimes it is required to repair the hardware of the entrance or interior iron door. If we are talking about an interior door, then repair or replacement of the mechanism is usually carried out when the handle falls out.

To carry out repair work, follow these steps.

• Detach the base from the door leaf.
• Look at the condition of the retaining ring. If the ring has shifted, then you should adjust its location. If it breaks or bursts, it should be replaced.

Also, the handle is repaired if, after opening, the fittings do not return to their normal position. Displacement or breakage of the coil is the cause of the problem.

To replace the spiral, you need to do the following:

• dismantle the device;
• pull out the damaged part and replace it;
• now fixation should be carried out using the locking mechanism;
• the structure is mounted on the door.

If the spring has burst, then you can make it yourself from a small piece of steel wire. The workpiece must be heated over a fire until it is bright red, and then dipped into water. Then it can be applied.
