Sections of the article:

Before determining what is good and bad for a particular mechanism for sliding doors, it would be advisable to short review its most common types. Most doors use only three design principles: sliding, swinging open and folding.

Of these three, swing doors are the most popular. They historically appeared earlier than others and have a design familiar to everyone: the door is fixed in the opening with hinges and can move in one of two directions. This design has a significant drawback: when open, the door occupies a fairly large area.

Folding doors are used relatively rarely. Sliding door mechanisms of this type involve the movement of several panels with the help of springs, allowing the structure to fold quite compactly. You can observe this type of door in public transport. The disadvantages of this type of construction include a small degree of sound insulation.

Sliding door design

The construction set of mechanisms for sliding doors, in addition to the door panels, also contains a number of parts necessary for assembly. Here is a list of the standard delivery items:

door panels;
Box;
Guide elements;
Fittings;
Cassette.

The listed parts are included in the standard minimum, so even the absence of one of them may make assembly impossible.

door panels

The number of panels for a sliding door can range from one to eight. As door panel any door can be used, except for doors with a non-standard profile, such as, for example, arched doors.

Single sheet system.

door frame

Despite its name, the door frame is U-shaped. This structural element is placed in the opening, and panels are mounted directly on it using the mechanisms of sliding interior doors. The process of mounting the box is carried out using screws or adhesives.

Most often, the door frame is completed decorative elements, whose only function is to enhance the aesthetic qualities of the door.

rail mechanism

The rail mechanism is the part that performs all the functionality of the sliding door mechanism, so the installation process of this element should be taken with all responsibility.
To limit the possible gap of movement of the door, two limiters are provided, one of which is attached from below, and the second from above.

The number of rollers that ensure the sliding of the door along the guide rails should depend on the mass of the door leaf: the greater the mass, the more rollers.

The rail mechanism is pretty complex design, so it is not recommended to choose it yourself. best solution will purchase this roller mechanism complete with panels for sliding doors.

accessories

For the most part, this class of parts includes a variety of doorknobs. But in the case of sliding doors, the handles must have a special shape that minimizes the protrusion of the handle beyond the surface of the door leaf. This design allows you to hide the sliding mechanisms in the door cassette.

The standard set of mechanisms for sliding interior doors already includes such a handle, but if necessary, you can choose and mount the appropriate fittings yourself.

Sliding door fittings also include cylindrical elements that allow the door panel to move with a light touch of the fingers.

Cassette

This structural element may not be included in the standard configuration. retractable door. Its principle can be illustrated by the example of a video cassette: if we imagine that the door leaf is a video cassette, then the cassette is a box in which the video cassette fits compactly.

Our apartments mostly have standard hinged doors. For owners of small-sized housing, such doors cause a lot of problems, as they take up a decent amount of space. usable space which can and should be used more efficiently. The way out of this situation is the installation of sliding doors. In them, the door leaf moves along the wall, thus freeing up usable area.

Types of sliding door mechanisms

Sliding mechanisms for interior doors are represented today by two types.

The first type of such a mechanism includes two guides - both upper and lower. Sliding doors with such a mechanism are free from distortions, and two pairs of rollers ensure quiet operation.

The second type of mechanism has a special stop in place of the lower guide. This option is not particularly reliable, since the door turns out to be suspended in the air and it is not very convenient to close it.

rollers play important role in the sliding mechanism. In the future, the entire process of operating doors depends on their type and quality. Cheap sliding door mechanisms are usually equipped with plastic wheels without bearings. Is not in the best way affects both the service life of the door and its performance.

The best option today is rollers with silicone bearings or rubber tires on top. .

When choosing a sliding mechanism, it is imperative to keep in mind the weight of the entire structure: for a door weighing 40-75 kg, a mechanism with two rollers is quite suitable. If the door is more massive (weighing 75-120 kg), then a mechanism with four wheels is already required. It must be remembered that there is no need to save on the mechanism of sliding doors. A good expensive design needs a good reliable sliding mechanism.

For different types sliding doors needed different kinds sliding mechanisms and guides:

when installing a cascading door, 2 roller mechanisms are installed on each door leaf, and the guides should, of course, be with two gutters;
for glass sliding doors, guides are installed both above and below;

Tools and materials

The following materials are required for mounting the sliding door mechanism:

door leaf (this is the main element);
wooden beam 40x40 mm. The length of the beam must be equal to the guide rail;
aluminum profile;
a set of rollers - hanging or supporting;
limiters;
fixing kit;
aluminum profile - 2 m.

For work, you should prepare the following tools:

screwdriver;
drill;
building level;
roulette;
chisel;
a hammer.

Installation instructions for the sliding door mechanism

A sliding door should be attached to the wall near the doorway and marked on the wall (necessarily both in closed and in open position) its upper edge.
From the measured edge, you need to mark 70 mm upwards and draw a horizontal line. This is the level of the top edge of the guide mechanism.

The wooden block is attached to the wall. Its bottom edge should be as accurate as possible along the line. The middle of this bar should be above the upper corner of the door opening on the side where the door will move.

The edge of the upper guide is applied from below, to the end of the bar. The extreme hole is marked at a distance equal to half the door thickness + 3-5 mm. The guide is fixed with a self-tapping screw, the second screw secures the other edge of the guide. The distance from the guide to the wall should allow the door leaf to move.

Support carriages are assembled on the sliding door mechanism.
The assembled carriages are inserted inside the top rail. Then you need to check if they move easily.
Travel stops with rubber shock absorbers are installed on the edges of the guide. The non-threaded plate is placed outside the profile, and the threaded plate is placed inside it.

Next, a longitudinal groove is made - at the bottom of the door leaf, 15-18 mm deep and 1-2 mm wide more than the lower guide flag. It is not necessary to lubricate this groove with grease.
Along the edges of the aluminum guide, insert travel stops equipped with rubber shock absorbers.

Important. When mounting round shock absorbers without a retainer, a metal plate with a thread is placed inside the profile, and a plate without a thread is placed outside.
Next, a longitudinal groove is made in the lower part of the door leaf. This groove can be lubricated with any suitable lubricant.

Stepping back from the edge of about 2 cm, mounting brackets are mounted on the door - in the middle of the door thickness, on the upper end. The semi-circular cutouts of the brackets should face the wall.
The door leaf is hung.
The lower guide roller (or knife, or flag) is installed.

The door is adjusted vertically.
A decorative strip is mounted, it covers the sliding mechanism and 5-10 mm of the upper door edge. It can be either fixed or retractable. It can be pasted over with wallpaper - the same as the wall, or you can immediately purchase it to match the desired color of the door.

The installation process of the sliding door mechanism is almost completed. It remains only to make sure that the design works properly.

Sliding doors are a very convenient and compact design, which is perfect not only for dividing interior space, but also for zoning rooms. It's universal modern version which is very popular. When choosing sliding doors, it is important to know what mechanisms they have and how they work.

Kinds

Sliding interior doors depending on their design are divided into certain types. So, there are:

Rail with a different number of wings

These can be structures with a rail at the top or bottom, there can also be two-rail models. The most popular are products on one upper rail. They look very elegant and unusual. These doors can be either single or double doors. It all depends on the width of the passage in which they are installed.

Radius

These doors are quite unusual and completely transform the interior of any room. They are quite massive. All such designs have the shape of a semicircle. As a rule, they are made of tempered glass with a thickness of at least 8 mm. This design also assumes the presence of a rail mechanism. This type of door is perfect for zoning.

"Harmonic"

These are models that fold sideways and each sash is assembled in a zigzag pattern. Each section of such a door is superimposed on each other in turn and the door folds very compactly. The design looks very light and usually has bright design. They can be installed in any passages.

Rollback

Such a mechanism assumes that when the door moves, the leaf moves inward and to the side. This type of door is a sliding door. In this case, on the wall adjacent to the entrance there is a special frame in which the sash is located at the moment when you open the door. In addition, such models may have specially designated places in the wall in which this structure is hidden.

Combined

Principle of operation

Most models have mechanisms with guides. The door leaf is usually presented in the form of one or two wings, but there are also models with large quantity sashes. The canvas moves along the guides located above and below on special rollers. So, there are models with a single-track type of movement, in which the lower guides are completely absent, and the canvas moves along the top.

Two-track type - when the door moves along the bottom rail, and it is held on top by a stop to ensure an ideal vertical position. Such a principle of operation have structures with a large weight.

The principle of movement of the sash can be different. She can move along the wall, as if superimposed on it. The second option is to move inside the wall. It would be correct to say that door leaves hide not inside the wall, but inside the cassette located there.

Another option is overlapping movement, when one movable sash overlaps the main deaf, standing without movement. This option is the simplest, but not very convenient, it is completely unsuitable for narrow aisles.

Design options and their characteristics

Door designs can be varied. So, there are the following types:

Synchronous

This option is different in that it allows you to open two doors at the same time. In this case, the door leaf is divided in two and opens into different sides along the wall. As a rule, lighter materials are used for this, since in general the design will not withstand a heavy door leaf. The design includes rollers, guides, a cable, a hook, as well as special devices for fasteners. It's quite complex, but in general reliable mechanism. It will be quite difficult to install such a door on your own, so installation is most often trusted only by professionals.

Telescopic

This design option is suitable for installation if the sliding system includes at least two doors. As a rule, these are two or three doors, which move in one direction when opened. The doors are fixed with a special synchronizer and are placed not on one rail, but on two different, parallel ones. Thus, the sashes also move apart synchronously, but one main sash pulls all subsequent ones. This design is fixed either at the top of the doorway or at the bottom with an aluminum profile. It is along them that the sashes move with the help of support carriages.

As a rule, rubberized rollers are used in this design, which allow the structure to move very smoothly and silently.

Invisible

This is a very handy mechanism. hidden type, which hides behind a specially designed fake panel. In another way, this design is called compartment. For its installation, a threshold is not used. This mechanism is fixed on the top of the door.

A feature of the invisible mechanism is that its installation is possible only if initially during construction a place was provided for it inside the wall.

If the thickness of the wall is not enough to hide sliding doors in it, then a special pencil case can be used for this. Thus, this indicator can be increased by the size of the pencil case. An invisible mechanism is used only if the door is not glass. Such a door leaf in this case is unacceptable to use.

Suspension

Such a mechanism is otherwise called Standard. It is a construction without a threshold, which also does not have a bottom rail. The door slides only along the top rail. The structure itself is of an open type and moves to the side along the wall. Hanging doors of a sliding type can be easily installed by hand.

barn

The mechanism of this type is most often made of steel. This design is of an open type and includes a steel guide, rollers and a door leaf. This mechanism is most often purchased for fairly spacious aisles. The barn mechanism differs in noiselessness and smoothness of the course. Usually, given quality provide reliable bearings. Often this mechanism is supplemented with a special closer.

Tram

This design option has rollers not from below, but from above. That is, the guides are most often located on top, and the door structure is attached to them with the help of special elements and moves along it with the help of special rollers that roll only along the upper part of this skid. This mechanism is perfect for decorating an apartment or house in a retro style.

shut-off

Such a sliding structure implies the presence additional fittings in the form of a lock or lock mask. The latch or lock is mounted in the locking mechanism, which will be triggered at the moment the lever is pressed. The locking mechanism may be different. For this, buttons are often used, which at one moment are able to block the movement of the door. So you can close it and lock it or open it and fix it in a position convenient for you. The locking mechanism is installed in any door leafs. Such designs can be with a latch, turnkey or magnetic.

Sliding systems

There are also various variations extension systems.

coplanar

Such a system assumes the presence of a separate skid for each door leaf. Thus, when you open this structure, each half runs over and the other on top of it. Most often in this case, models with two door leafs are used. But if there are three canvases, then the sliding system becomes three-sliding.

An alternative option for a coplanar extension system is to install the central section on a separate skid, and the two extreme ones on one common one. Thus, it will not be possible to open two sections at once, since two door leaves located on the same skid will not allow this to be done. AT closed they have a stepped design open type. One part of the guide will always be visible.

Door leafs are installed in individual skids more often than in common ones. This option is suitable for both two and three door panels. This way, when the doors close, they line up and close the rails. For this, the extension system is supplemented with special brackets with a running mechanism. Such a door is somewhat reminiscent of a compartment, but when opened, the canvas shifts slightly forward and to the side, which is different from a compartment door. Closing the door, the canvases are put in place and the ladder system becomes invisible.

The coplanar sliding system is different in that it is a combination of several types of mechanism at once.

This is a very comfortable and versatile design.

Fast

This is a system whose mechanism is based on supports. It does not have a frame and it also needs guides. As a rule, these can be single or double designs. As guide material sliding systems This type uses both metal and plastic. But the guides themselves are usually very narrow, so they save space in the room. To install such a door, milling is not required.

Ghost, or hidden

This design and all door fittings are completely closed from prying eyes. The guides are not visible either above or below the opening. Most often, it is still located on top, but is very inconspicuous, thereby expanding the space. There are very convenient hidden models in which the guides are not located in door frame but directly inside the door. Thus, only the mount and rollers are mounted on the wall. So the sliding system becomes completely invisible, and when you see it, you even get the feeling that the door is literally floating in the air. Such models of doors and sliding systems are perfect for more modern interiors, as they look very unusual and elegant.

Aristo, or rotary

It is characterized by the fact that it works from rotary mechanism. As a rule, it is used to create aluminum profiles and other accessories from the same material. This is one of the most reliable and durable sliding systems, which at the same time saves space. It is quite easy to install and operate.

Advantages and disadvantages

A huge advantage of any sliding design is its compactness. It allows you to reduce doorway and makes it lighter. It is also able to make the passage wider and higher, especially suspended models. Sliding design does not require a swing, so you can furnish the room into which the door leads at your discretion, without taking into account the design of the door.

It is also a great advantage that this the door moves very smoothly and silently. She will not wake up the household with unnecessary claps and other loud sounds. In addition, the sliding door mechanism prevents animal tails or children's fingers from flapping, as the door closes very smoothly.

Separately, it should be noted the advantages of coplanar sliding door systems. This mechanism minimizes the appearance of unnecessary gaps, which cannot be said about other doors. This ensures not only the proper level of sound insulation, but also the whole structure, when closed, creates a feeling of unity. Another advantage of the coplanar system, as well as other types of closed structures, is that the guide skids are closed from prying eyes. In addition, since they are inside the structure, dust and dirt do not accumulate on them, so it becomes quite easy to care for the structure.

The coplanar system has a lot of advantages over compartment doors, since the passage is completely free and the door takes up much less space. The same can be said about the models - "accordions", since they are compactly assembled around door jamb when opening.

The sliding door mechanism has various latches, which is its undoubted advantage. This way you can fix the door in a fully open, half-open or closed position and you can adjust and make it easier for yourself to pass. In addition, such a mechanism and this function allows you to prevent the doors from slamming at the wrong time.

Another advantage of sliding doors is that they do not require a small amount of space and can be installed by almost anyone. This applies most simple mechanisms, such as a coupe or an accordion. In addition, a big advantage is appearance such products. They look more interesting compared to classic swing doors. There are more options for design and selection of different types of mechanism.

But such doors have a number of disadvantages. So, some systems, such as coplanar, have limitations in the size of the doorway.

They are only acceptable if the width of the door leaf is between 150 and 300 cm. If the width doorway more or less, then installation will be impossible. These systems also assume the presence of restrictions on weight. The door must weigh no more than 55 kg, otherwise the mechanism may not withstand. The same applies to hanging sliding doors.

The disadvantage of almost all sliding doors and their mechanisms is that they cannot provide the proper level of sound insulation. This is due to the fact that the sliding system is not completely airtight, in which it is very inferior to swing structures. This shortcoming is due to the fact that the design includes a lot constituent elements and there are gaps between them. That is why sliding doors are very rarely used for installation in the kitchen or bathroom. They easily let in smells, extra noise and can distract other household members.

Noisy meeting rooms it is better not to install such doors, since sounds will penetrate anyway. Due to the low tightness, the sliding door mechanism does not allow for proper thermal insulation, since cold air flows can penetrate from one room to another, forming drafts.

Another disadvantage is the high cost of such structures compared to classic swing. By itself, this mechanism is not very reliable and requires special care. It must be lubricated and checked periodically.

swing doors more durable to external influences, compared to sliding. FROM protective function sliding models do not cope. In addition, some mechanisms can jam, especially hidden types that hide inside the wall.

Thus, to correct this shortcoming, you may even have to dismantle the wall, which is difficult and problematic.

How to choose?

Hinged synchronous mechanisms are more suitable for light door panels. This is due to a complex design and in the first case, the presence of an upper guide, and in the second, the presence of several parallel guides. They are also perfect for plastic structures. For doors - "accordions" often use fabric elements.

The most versatile is the chipboard door. Such material is lightweight and practical, in addition, it is quite inexpensive. On a par with them are universal models made of MDF, which also fit any door mechanism. Such models are often pasted over with veneer or decorated with carvings by milling.

For many sliding door mechanisms, an important requirement for the canvases is the presence of absolutely identical sashes. That is, they must be equal in length and width.

This applies to both coplanar models and accordions, synchronous models and sliding doors. Hidden-type telescopic structures are completely unsuitable for the use of glass doors.

For pencil cases, you can even pick up heavy models made of wood. For folding mirrored doors, you can use the compartment mechanism. For lightweight door structures, almost any type of mechanism can be used. In this case, you can choose a telescopic, hidden, synchronous mechanism, as well as rotary or radius products. For models with two doors, a coupe-type mechanism is most suitable.

When choosing a mechanism for sliding doors, great attention must be paid to the materials from which it is made. It is better if it is metal, even if the door frame is wooden. When choosing, try not to save on the purchase of such doors. Otherwise, the design will serve you for a very short time.

Much attention is paid to the roller system. This is especially true at the time of installation, since a skew or incomplete set constituent parts and guides can lead to breakage of the entire structure. When choosing, also rely on allowed materials for a specific mechanism, as well as the weight of the structure itself. If the mechanism is not too reliable, then it is better to give preference to light materials for the door. When choosing a mechanism, try to also take into account the size of the doorway and the canvas itself.
