Sliding mechanism for interior doors

To ensure that the operation of interior door leaves in the house does not take up useful space when opening/closing, it is enough to install mechanisms for sliding doors with gates built into the system. The operating principle of this design is simple - the blades are equipped with rollers and move along special rails (guides) back and forth. To prevent shock loads, they are equipped with stoppers and limiters. They are distinguished by quiet operation, ease of maintenance, reliability, and visual appeal. For the production of doors, MDF boards, glass, mirrors, and solid wood are used. Fittings for sliding doors are selected depending on the weight and area of ​​the door panels, taking into account the type of material from which they are made.

Sliding mechanism for interior doors It is structurally divided into types and differs in the method of installation (location) of the working rollers. They are installed in the upper or lower part and can have a combined sliding mechanism. In the first case, the main load is placed on the upper rollers, while the lower mechanism supports the movement of the doors and prevents impacts when opening. In the second option, the lower rollers are working, and the upper ones are auxiliary. In the third, the load is distributed across two mechanisms simultaneously. Depending on the weight, design, and area of ​​the target, the number of rollers is determined. Their number varies from two.

Guides sliding fittings made from steel or aluminum. They are available in single and double types. Attached to the stream and/or floor.

The TBM-Market company offers to purchase high-quality sliding door mechanisms for compartment doors. Experienced enterprise managers will help you select the necessary system for the flawless operation of your doors and components for their installation - from fasteners to seals.

Traditional swing doors aren't for everyone. But sliding systems have a lot of advantages - they do not “slam”, move silently and do not take up part of the usable space of the room. To ensure that the result of their installation does not disappoint, you need to know what types of mechanisms there are for sliding doors and how to choose them for a specific design.

On a note!

• When looking for a ready-made mechanism kit, you should take into account not only the specifics of blade displacement, but also the complexity of installing and adjusting the system.
• At self-production structural elements, the peculiarities of movement of door leaves and their installation location are taken into account.

Components of the kits

Different mechanisms in their design sliding doors differ little from each other, except perhaps in the specific displacement of the valves. Therefore, the kits include almost the same elements; the only difference is in their number and design.

Rails

Profiles are mainly used as guides in sliding door systems.

The difference between them is the number of “tracks”. The specifics of the application depend on how exactly the canvas covers the opening: end-to-end or overlapping. In fact, these are traditional sliding doors, well known to many. When choosing a profile, the metal from which it is made also matters. For massive doors, it is better not to use aluminum (even though it is cheaper); Deformation will cause problems with sliding doors - only steel.

Roller bearings

They also differ in design features. Required amount wheels (and the upper mechanisms can have up to 8) is determined by the mass of the web and the type of sliding system. There are also differences in the arrangement of the wheels: symmetrical or offset (asymmetrical). For doors weighing no more than 80 kg, roller mechanisms with two supports can be used. But for massive canvases, at least four are installed, which is associated with an increased load on the structure.

Locking elements

They are not basic, but they do important functions. The first is to prevent a “hard” impact of the door on the wall (if the opening is located close to it) or the roller flying out of the guide. Such parts are called motion limiters. The second is fixing the door in a certain position. This is necessary in order to prevent spontaneous movement of the canvas. This is possible, for example, in the event of a strong draft or disruption of the horizontal orientation of the rails due to shrinkage of the structure.

The sliding door mechanism can be additionally equipped with automation elements (closers, mini-electric motors, cables, hooks, etc.). But they do not make any changes to the principle of its functioning; They only increase ease of use, nothing more.

Types of sliding systems

Open type

These are the simplest modifications. The sliding mechanism consists of roller supporting elements and guides. The number of the latter determines the specifics of the door’s operation, its stability in the opening and a number of other factors. Why open? The fact is that such designs are universal in installation. They can be mounted in any opening, regardless of the wall material and its structure; it makes no difference whether it is solid or hollow (that is, a partition).

With one rail

Such systems are called suspended, non-threshold, upper. They are the easiest to install, and therefore are often installed in apartments. This is explained by standard openings, therefore, the door sizes are chosen relatively small. The disadvantage is that there are only limiters at the bottom, and there is no fixation of the position of the canvas. Therefore, there is some difficulty in determining it optimal thickness, that is, masses. Too much light door will begin to sway in the draft. This will not particularly affect the design itself, but in terms of comfort, such a prospect is unlikely to suit anyone; periodic “tapping” will cause irritation in any person.

There is one more negative point - you can forget about soundproofing the room. Therefore, the installation of such a system has a number of limitations. For example, if we're talking about about the opening leading to the office or bedroom - not the best option sliding door. But here you can find a positive point - hanging canvases do not interfere natural circulation air flows.

It is worth noting that in such systems, not only profiles are used as a guide, but also metal rods and pipes. And this diversifies the choice of installation options.

With two guides

Such systems are called floor-standing. The difference is that the rails are fastened both at the top and at the bottom. Accordingly, the number of roller mechanisms. Despite a certain installation complexity (for example, the accuracy of projecting the guide axis from the ceiling to the floor when marking), such a sliding mechanism provides a number of advantages.

• It can withstand significant load. That is, it allows you to install massive panels in the opening without any special restrictions.
• Sliding doors are always static. If the lock is installed, the canvas will not “knock” even in a strong draft.

Closed type

Such systems are installed much less frequently. Their difference is that the doors “go” into the wall, that is, after opening, the door is partially or completely hidden in it. But this is only possible in the case of interior partition, and frame type. It is hollow inside, and therefore there are no obstacles to moving the door.

• Originality of the system.
• Ease of use. There are no guides on the floor or ceiling, therefore, their useful area is not reduced.

• Low maintainability. If problems arise with the limiter or sash, you will have to remove part of the cladding from the partition. Replacing the roller mechanism will also be quite difficult. Especially if the sliding door closes with overlapping panels. Their dimensions in width exceed half of the same parameter of the opening, and therefore here it is impossible to do without removing part of the cladding from the wall.
• Difficulty of care. No matter how clean the owners are, dust will gradually accumulate in the profiles. As a result, incorrect operation of the sliding system, jamming of doors, and so on. How to remove contamination is a separate question, but it should be taken into account.

The design of the hidden mechanism for sliding doors is not much different from that used in structures open type; its composition is completely identical. It is so called because various decorative strips are placed on top, which cover the structural elements.

There is also combined option systems with two guides. It is mounted if heavy blades are selected that create a large load on the rollers. It is not always possible (or advisable) to increase their number. Therefore, the solution is the following - use both the lower and upper wheels as supporting elements. This allows the weight of the sliding door to be evenly distributed over the entire area. The convenience is obvious - the control of the shutters is greatly simplified. They move even with a light touch on the handle. For families with small children – best option systems.

When choosing (or making your own) a mechanism for sliding interior doors, first of all you need to take into account such characteristics as load capacity. All other factors - the specifics of installation in place, opening / closing - should fade into the background. Otherwise, even with professional installation The system will have to be repaired in a couple of months.

Sliding doors are a very convenient and compact design that is perfect not only for dividing interior space, but also for zoning rooms. It's universal modern version, which is extremely 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. Yes, there are:

Rail with different numbers of leaves

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

Radial

These doors are quite unusual and completely transform the interior of any room. They are quite massive. All such structures 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.

Recoil

This mechanism involves moving the door inward and to the side when the door moves. This type includes a sliding door. In this case, on the wall adjacent to the entrance there is a special frame in which the leaf 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 leaves, but there are also models with a large number of leaves. The canvas moves along guides located above and below on special rollers. Thus, there are models with a single-track type of movement, in which the lower guides are completely absent, and the canvas moves along the upper one.

Double-slide type - when the door moves on the bottom rail, and is held on top by a stop to ensure an ideal vertical position. Heavy weight structures have this principle of operation.

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

Another option is movement with overlap, when one movable leaf covers the main blind one, which stands without movement. This option is the simplest, but not very convenient; it is completely unsuitable for narrow passages.

Design options and their characteristics

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

Synchronous

This option differs in that it allows you to open two doors at once. In this case door leaf splits in two and opens into different sides along the wall. As a rule, lighter materials are used for this, since the overall structure will not support a heavy door leaf. The design includes rollers, guides, cable, hooks, as well as special devices for fastening. This is a rather complex, but generally reliable mechanism. It will be quite difficult to install such a door yourself, so installation is most often trusted only to 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 secured with a special synchronizer and placed not on one guide, but on two different, parallel ones. Thus, the doors also move synchronously, but one main door pulls all subsequent doors. This design is fixed either at the top doorway, or at the bottom using aluminum profile. It is along them that the doors move with the help of support carriages.

Typically, this design uses rubberized rollers, which allow the structure to move very smoothly and silently.

Invisible

This is a very convenient hidden type mechanism, which is hidden behind a specially designed false panel. In another way, this design is called a compartment design. No threshold is used for its installation. This mechanism is attached to top part doors.

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

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

Suspension

This mechanism is also called Standard. It is a design without a threshold, which also does not have a bottom guide. The door slides only along the top rail. The structure itself is open and moves to the side along the wall. Mobile hanging doors can be easily installed with your own hands.

Barn

Mechanism of this type most often made of steel. This design is of the open type and includes a steel guide, rollers and door leaf. This mechanism Most often purchased for fairly spacious passages. The barn mechanism is quiet and smooth. As a rule, this quality is ensured by reliable bearings. Often this mechanism is supplemented with a special closer.

Tram

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

Locking

This sliding design requires the presence of additional fittings in the form of a lock or lock cylinder. The latch or lock is mounted in a locking mechanism that will be activated when the lever is pressed. The locking mechanism may be different. To do this, they often use buttons that can immediately block the movement of the door. So you can close it and lock it, or open it and lock it in a position convenient for you. The locking mechanism is installed in any door leaf. Such designs can be locking, turnkey or magnetic.

Sliding systems

There are also various variations of sliding systems.

Coplanar

Such a system assumes the presence of a separate runner for each door leaf. Thus, when you open this structure, each half slides over the other half. Most often in this case, models with two door leaves are used. But if there are three panels, then the sliding system becomes three-slide.

An alternative to the coplanar sliding system is to install the central section on a separate runner, and the two outer 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 slide will not allow this to be done. IN closed they have a stepped open type design. One part of the guide will always be visible.

Door leaves are installed in separate runners more often than in common ones. This option is suitable for both two and three door leaves. This way, when the doors close, they line up and cover the tracks. For this purpose, the sliding system is supplemented with special brackets with a running mechanism. Such a door is somewhat reminiscent of a compartment, but when opened, the door leaf moves slightly forward and to the side, which makes it different from a compartment door. By closing the door, the canvases are put in place and the ladder system becomes invisible.

The coplanar sliding system is distinguished by the fact that it is a combination of several types of mechanism.

This is a very convenient and versatile design.

Fast

This is a system whose mechanism is based on supports. It does not have a frame and also requires guides. As a rule, these can be single or double designs. Both metal and plastic are used as materials for guides for sliding systems of this type. But the guides themselves are usually very narrow, so they save space in the room. No milling is required to install such a door.

Ghost, or hidden

This design and all door furniture 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 invisible, thereby expanding the space. There are very convenient hidden models in which the guides are not located in door frame ke, but directly inside the door. Thus, only the mount and rollers are mounted on the wall. This way 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 door models and sliding systems are perfect for more modern-style 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, aluminum profiles and other components made from the same material are used to create it. This is one of the most reliable and durable systems sliding, which at the same time allows you to save room space. It is quite easy to install and operate.

Advantages and disadvantages

A huge advantage The main advantage of any sliding structure is its compactness. It allows you to reduce doorway and makes it easier. It can also make the passage wider and higher, especially when it comes to hanging models. The sliding design does not require swinging, so you can furnish the room into which the door leads at your discretion, without taking into account the design of the door.

Another big advantage is that this the door moves very smoothly and silently. She will not wake up household members with unnecessary claps and other things. loud sounds. Besides, sliding mechanism The door prevents animals' tails or children's fingers from slapping 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 entire closed structure creates a feeling of unity. Another advantage of the coplanar system, like other types closed structures is that the guide rails are closed from prying eyes. In addition, since they are located inside the structure, dust and dirt do not accumulate on them, so the structure becomes quite easy to maintain.

The coplanar system has many advantages over compartment doors, since the passage is completely cleared and the door takes up much more space. less space. The same can be said about accordion models, 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 lock the door in a fully open, half open or closed position and can adjust to make it easier for you to pass through. In addition, this mechanism and this function helps prevent doors from slamming at the wrong time.

Another advantage of sliding doors is that they do not require small space and almost anyone can install them. This applies most simple mechanisms, such as coupe or accordion. In addition, the appearance of such products is a big advantage. They look more interesting compared to classic swing doors. Exists more possibilities for design and selection different types mechanism.

But such doors have a number of disadvantages. Thus, some systems, such as coplanar, have restrictions on the size of the doorway.

They are acceptable only if the width of the door leaf is from 150 to 300 cm. If the width of the doorway is larger or smaller, then installation will not be possible. These systems also have weight restrictions. The door should weigh no more than 55 kg, otherwise the mechanism may not withstand it. 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 sealed, in which it is very inferior swing structures. This drawback is caused by the fact that the design includes many components and there are gaps between them. This is why sliding doors are very rarely used for installation in the kitchen or bathroom. They easily let in odors, excess noise and can distract other household members.

In noisy rooms for meeting guests It is better not to install such doors, since sounds will penetrate in any case. Due to low airtightness, the sliding door mechanism does not allow for proper thermal insulation, since cold air currents can penetrate from one room to another, forming drafts.

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

Swing doors more durable to external influences compared to sliding ones. WITH protective function sliding models can't cope. In addition, some mechanisms can jam, especially the hidden types that are hidden inside the wall.

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

How to choose?

For lightweight door panels, hinged synchronous mechanisms are more suitable. This is due complex design and in the first case, by the presence of an upper guide, and in the second, by the presence of several parallel guides. Perfect for them too plastic structures. Fabric elements are often used for accordion doors.

The most versatile door is made of chipboard. This material is lightweight and practical, and it is quite inexpensive. Along with them are universal models made of MDF, which are also suitable for any door mechanism. Such models are often covered with veneer or decorated with carvings by milling.

For many sliding door mechanisms, an important requirement for the door leaves is the presence of leaves that are absolutely identical in size. That is, they must be equal in both length and width.

This applies to both coplanar models and accordion, synchronous models and sliding doors. Telescopic structures hidden type are completely unsuitable for use glass doors.

For pencil cases, you can even choose heavy wooden models. For folding mirror doors you can use the compartment mechanism. For the lungs door designs 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, the 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 purchasing such doors. Otherwise, the design will not serve you for very long.

Much attention is paid to the roller system. This is especially true at the time of installation, since a misalignment or incomplete set components and guides can lead to breakdown of the entire structure. When choosing, also rely on the acceptable materials for a particular mechanism, as well as the weight of the structure itself. If the mechanism is not very reliable, then it is better to give preference to lightweight materials for the door. When choosing a mechanism, try to also take into account the size of the doorway and the door leaf itself.

Sliding interior doors are increasingly being installed not only in apartments, but also in country houses, office buildings. Such sections have a number of advantages, the main of which are saving space and increasing usable area premises.

Advantages and disadvantages of interior sliding doors

The choice of this functional interior element is due to a number of advantages:

• increasing the usable area of ​​the room;
• do not slam shut in drafts;
• they cannot be opened by pets;
• possibility of automating the mechanism;
• no thresholds.

Sliding systems for interior doors also have disadvantages: first of all, poor sound insulation and high cost of fittings. The first occurs when the mechanism is built into the wall. If you place the sliding door mechanism along the wall, sound transmission will decrease.

Mechanisms for sliding interior doors can be improved by installing special sensors. Additionally, access levels can be taken into account when automating sliding doors. That is, the door can open according to the code, plastic card or fingerprint.

Design and types of sliding doors

Sliding systems for interior doors consist of the door leaf itself, guides and a roller mechanism. Different kinds doors may include more than two roller mechanisms, several doors and guides. Let's look at the operating principle and design of sliding doors. The mechanism for a sliding interior door works as follows: a roller mechanism is attached to the leaf, as a result of which the rollers move along the guides, opening or closing the door.

There are many types of such products, but the most popular are the following: sliding doors interior; cascade sliding; folding accordion type; radius. The latter are the most difficult to install. The most commonly used doors are sliding doors, which are the easiest to install.

About the quality of components

The mechanism for a sliding interior door is selected based on the following factors: weight, material and height of the door leaf, the need to be built into the wall, the number of rollers. How more complex system, the better the fittings should be. Thus, single-leaf interior sliding doors are lighter in weight than double-leaf ones, and components for such a product can be chosen that are simpler and lighter.

Most ready-made kits are equipped with plastic rollers, which are not durable. It is necessary to select a mechanism for a sliding interior door in advance, while it is still in process. finishing works so that you don’t have to correct the finishing of the walls and floors.

Canvas material

Classic wooden interior doors are most often installed. High quality material(oak, maple, cherry) quite expensive, but the most durable.

Products made from fiberboard are cheaper, do not deform, but are inferior in quality to their more expensive counterparts. These doors are characterized by low strength and fairly good sound permeability.

MDF canvases are distinguished by an average level of quality and durability. The most elegant doors are made of solid wood, but such products will be very expensive.

Sliding glass interior doors are becoming increasingly popular. They use special safety glass, which makes them safe to use.

Glass is tempered during processing during the manufacturing process, so it can be stronger than wood. Products made from this material differ in many parameters: material thickness, appearance surfaces, properties. They can be installed in rooms with high humidity- swimming pools, bathrooms. A glass door is easy to maintain and environmentally friendly.

Plastic sliding doors are better suited for installation in administrative premises.

To decorate the interior, you should give preference to door leaves made of solid oak or tempered glass. Such products can become the highlight of the room and emphasize the status of the owners.

Selection of components

Accessories for has great importance. Poor quality will lead to rapid breakdown of the door mechanism. It is better to give preference to steel or aluminum when choosing a material; it takes on the main load. Despite the tendency to equip the mechanism with plastic wheels, it is optimal to replace them with metal ones.

The more metal parts- the more durable the door will be. With proper care, high-quality components can provide the system with decades of service. The fittings for sliding interior doors also include a special cassette if you plan to install the mechanism into the wall.

The locks and door handles in interior doors. They are “recessed” into the canvas, while in conventional swing doors they are installed on the surface. Locks and handles are usually included in the kit and match the style with other parts.

Stages of installation of sliding doors

Fasteners and instructions with step-by-step installation usually included in the finished kit. Usually sliding systems for interior doors they differ in the profile and type of roller system. That's why general principle installation will be the same.

Installation of a sliding door can be divided into several stages:

• marking and installation of guides;
• installation of brackets for roller carriages;
• installation of the canvas;
• installation of handles and locks;
• decorative finishing to disguise slopes and roller mechanism.

Information on how to install sliding interior doors is given in general view. When installing a sliding door, two installation options are possible - placing the panel along the wall or in the thickness of the opening.

Marking guides

To mark the guides, you need to measure the height of the door leaf and mark its size on the wall above doorway. From this point you need to step back seven centimeters and draw a horizontal line using it.

Installation of guides

The bottom edge must be applied to the drawn line. should be 50 x 50 mm. The beam is screwed to the wall using anchor bolts. In this case, its position must be strictly horizontal.

Several mounting holes are drilled in the metal guide in increments of no more than fifteen centimeters. This part is attached to the lower end of the beam at a distance of 5 centimeters from the wall. This distance is due to the need for the door to move freely along the wall.

Installing Roller Carriage Brackets

The rollers are assembled by connecting to the carriages and inserted into the guide. In this case, it is necessary to check the movement of the rollers along the guides. The wheels should move freely and without unnecessary noise. The ends are closed with plugs that serve as stoppers for the rollers.

Staples are installed at the upper end at regular intervals. In this case, the number of staples must correspond to the number of carriages.

Door installation

The canvas must be hung, connecting the carriages with brackets, and it must move easily and not touch the wall.

If everything is done correctly, you can continue installation. To do this, the door leaf must be opened all the way and mark on the floor the place where the lower guide element will be attached. After this, the door is removed again.

Using a router, a full-length groove is made at the lower end of the blade. In this case, the depth and width of the groove depends on the size of the lower leash. For free movement of the mechanism, it must be slightly larger.

The plumb line is fixed to the top guide. After careful measurements, the most accurate position of the leash is determined, which is screwed to the floor with self-tapping screws.

The canvas is installed in a vertical position and put on the leash with a groove. By adjusting the bolts of the carriages, it is necessary to ensure their correct placement. At this stage, the mechanism for the sliding interior door can be considered installed.

Next, you need to embed the lock and handle into the door leaf; as a rule, the hole for installation is already provided by the manufacturer, and the installation process is described in detail in the instructions. Often the kit comes with already installed lock and a pen.

Decorative finishing

The mechanisms for sliding interior doors have been installed, and only the final part remains - masking structural elements. Decorative box designed to hide the supporting beam. Platbands are installed along the perimeter of the entire structure to give it a complete look.

Today you won’t surprise anyone with a sliding door. Sliding structures Easy to meet everywhere. They are used for any type of door, including glass and metal, but are more often used as interior doors and sliding wardrobe doors.

In most cases, cabinets are assembled and installed by hand. The assembly and installation scheme is not very complicated. It is important to choose a high-quality sliding mechanism and strictly follow the chosen pattern.

Advantages and disadvantages of sliding structures

The main advantages of using sliding structure are the following:

• Space saving.
• Easy to install, allowing you to install them yourself.
• No need to install the box.
• Quiet operation, reliability and durability.
• Reducing the risk of injury.
• Possibility of installation tightly in any size and system automatic control.

The disadvantages include low tightness and the need to install a pencil case (in some cases).

Types of sliding doors

Sliding doors differ from sliding mechanisms. The latter can be folding, in which the doors are folded into an “accordion” or “book”.

Sliding structures differ in opening methods and the number of doors.

• Sliding doors. One or two sashes move along guides parallel to the wall in one or opposite directions. They are also used in Versailles coupe systems.
• Cassette. The difference from the first ones is that when opened, the doors are hidden in a pencil case. It can be made with your own hands from plasterboard, other materials, or purchased complete with a sliding structure.
• Radial. They differ in their original shape, determined by the curvature of the guides.

• Cascade. Each sash has its own guides. They come with one stationary and several movable blades.
• Intra-opening. The device assumes an option when, at the moment of opening, two doors move towards each other, and only part of the opening remains for passage

Sliding system design

Depending on the weight of the canvas, the sliding mechanism may have different designs. In a simplified form, the sliding door mechanism consists of the following structural elements:

• Guide with roller carriages. The number of these elements may vary for different types of doors. Most often made from thick-walled aluminum profiles, they are used for fastening door leaves in them. Polymer rollers on bearings are installed inside the rails, which provide the necessary smooth opening. Attached to the wall, floor or ceiling.
• Limiters or locking mechanisms. Used to hold the sash in the guide.

Types of sliding systems

Depending on the implementation of the design idea, sliding systems can have several guides. Most often one or two. The location of the support rollers can also be different:

• Up. This is the system hanging type. The canvas is suspended only from the upper guide. The load is distributed only on the upper rollers, and the door opens without touching the floor.
• At the bottom. This support system. The entire load falls on the lower guide. The upper suspension is not used.

The mechanisms themselves, according to their execution and purpose, are divided into the following:

• Standard. This is the simplest and most common option, which does not cause difficulties when installing it yourself. Typically non-threshold.

Designed for maximum load from 40 to 120 kg, the design has bearings.

• Open type. It is called so because all structural elements are visible. The hanger is designed for a door with a leaf weighing up to 100 kg. Let's say you can install the pencil case yourself.
• Hidden type. The structural elements are hidden behind the sash leaf. The bottom guide is not used. Not recommended for glass doors. Due to its simplicity, do-it-yourself installation is allowed.
• With closer. Special device ensures smooth movement of the valves. The closer is installed on any type of door and can work in both directions of movement of the leaves.
• Synchronous. The mechanism ensures synchronous opening of the doors in different directions. Designed for doors weighing no more than 80 kg. Additionally, the kit includes tension rollers, cable, fastenings and hooks. It is not recommended to install it yourself due to the complexity of the work.
• Telescopic. The mechanism ensures that the doors open in one direction. There are two parallel rails on which the doors are suspended, connected by a synchronous opening device. Suspension of up to three leaves is allowed.
• Rotary. This new type mechanism for interior designs. It has the advantages characteristic of sliding, swing and swing doors.

What is needed for installation

Do-it-yourself sliding mechanisms are installed on the doors using the following tools and components:

• Drill, screwdriver, screwdrivers.
• Fasteners - self-tapping screws, dowels and screws.
• Roulette.
• Pencil.
• Aluminum profile. For the standard Versailles design, it is enough to purchase a two-meter strip. Selecting the length for custom sizes openings are performed using calculations that can be found on the Internet.

• Wooden beam. One or two according to the number of upper guides. The thickness is selected according to the thickness of the blade, taking into account the dimensions of the mechanism. Usually - 4-5 cm.
• Limiters. The number of limit brackets must correspond to the number of rails multiplied by two.
• Guides. The slats should be smooth, and the material should be durable and light.
• Rollers with carriages. The sliding block is the most important part of the system. The service life and functionality of the entire system depends on its reliability and quality. This must be taken into account when choosing.
• Decorative plugs.

After preparing all this, we begin installation on the sashes. Installation can be done either on your own or with the assistance of specialists.

Installation

The installation diagram and procedure are as follows:

• The first step is to mark the position of the guides. The rails are installed 15-20 cm above the door, taking into account the height of the roller mechanism. Height is measured from the floor. On the wall are held horizontal lines, which are checked by level.

Irregularities can lead to spontaneous rollback of the sashes, especially when installing the Versailles coupe system.

• Then a beam is attached under the guide rails. It is mounted above the marking lines. Dowels are used.
• Guides are attached to the beam. Sometimes they are placed directly on the wall. Be sure to leave a small gap between the wall/beam so that the sash does not touch it. The length of the rail must exceed the width of the widow's opening.

• A block of roller carriages with fastening connections is inserted into the rails.
• Brackets are installed to lock the roller mechanisms. They are placed 5 mm from the edge of the canvas.

In the video you can see how to install the mechanism yourself:

• Next, the canvas is screwed to the brackets with screws. When installing the Versailles coupe system Special attention focuses on the absence of gaps. In the Versailles system they often appear anyway due to the synchronous movement of the rollers.
• Plugs are placed on the rails at the ends, and the sliding block is closed with platbands or decorative strips.

Installation of a sliding structure and an automatic control system is not so complicated. If you have the skills and follow the diagram, then anyone with little knowledge can install the sliding block with their own hands.

The quality of the components is important. Every element plays a role - sliding block, guide, suspension, stopper and even screw connections. Italian products are very popular, differing high quality. They provide exceptionally easy movement of the canvas and tight closure of the sashes.
