It's not quite that simple. Let's try to figure out how many there should be and on what criteria the number of hinges in the door depends. The main thing here:

The weight of the door should be evenly distributed between the hinges.
“Loop strength” is the mass for which it is designed. The number of hinges in the door design depends on the “hinge strength”.

Myth 2: The lock manufacturer is not important

In fact, it is not the size that affects the reliability of a lock, but its design features.

Each lock is tested for burglary resistance and assigned a security class from 1 to 4.

The most reliable and secure locks correspond to security class 4. At the same time, each manufacturer develops its own lock security system, and how more experience production, the more complex and reliable the protection will be.

Advice: choose locks from manufacturers who have been on the market for a long time, so you will be sure that the locks are tested not only for security, but also for durability. Find out what class the locks installed on the doors belong to. It is optimal if two locks are installed on the door various types, so opening the door will be twice as difficult.

Myth 3: fittings are the same for all doors

This myth is easy to verify in practice. If a door with conventional fittings is installed at the “street-house” border, then most likely, already in the first winter you will be able to observe irreversible consequences. From exposure to severe temperature changes and from exposure high humidity the coating on the handle will wear off, fade or become rusty.

Tip: when choosing an entrance door, ask your representative point of sale resistance of fittings to various types of temperature influences. If, for example, moisture-resistant fittings are produced, then they are made of a special multi-layer coating that is not susceptible to temperature fluctuations, high humidity and sun rays. Thanks to the use of this type of fittings, your doors will retain their ideal appearance as long as they are in use.

The result is this: choosing the front door special attention pay attention not only to the design of the door itself, but also to the hinges, locks and fittings.

The superiority of removable canopies over universal ones, analysis of “butterfly” and “invisible” hinges. Distributing the load and explaining why the third loop just ruins everything. Separate mini-review – ideal partners for a massive door.

1. “Let’s decide: heavy doors are how many in kilograms?”

Conditionally: from 50 kg. Anything lighter can be handled by regular mortise hinges with 2.5mm thick cards. But for doors heavier than 50 kg, it is better to buy thicker hinges.

In general, the weight of the canvas depends primarily on: a) the material and method of filling; b) dimensions; V) exterior finishing. So that you understand the average layout:

~ 14 kg – weight of a “cardboard” interior door without glass (800 x 2000 mm, thickness – 35 mm).

~ 17 kg – similar model, but with a wide glass insert from top to bottom.

A solid oak interior door (800 x 2000 mm, thickness 35 mm) weighs ~ 40 kg.

~ 75 kg weighs front door made of solid ash (900 x 2000 mm, thickness – 55 mm).

~ 115 kg – weight of a church oak door (1300 x 2300 mm, thickness – 60 mm).

These figures are valid for bare canvas and you should always keep the weight in mind decorative overlays(if any) and, of course, accessories. Alone door handles add 0.5-1 kg on top.

2. “How is the load distributed on the hinges holding a heavy door?”

Let's say we have classic version– door with two mortise hinges. Then the lower one bears the main axial load, and the upper one mostly takes the radial load. Simply put, the bottom hinge bears the weight of the sash, while the top hinge is subject to a force that tends to pull the hinge out of the jamb.

Door hinges wear mostly downward. Under the weight of the canvas, their halves are ground against each other, and bearings are gradually developed. As a result, over the course of a year, the interior door in the house drops by about 0.2-0.3 mm. That is, in 5 years it will inevitably sag by 1-1.5 mm. And this even with ideal conditions: adequately selected loops, proper installation etc.

Thus, the correct choice (taking into account the weight of the canvas) door hinges will allow you to delay as much as possible creaking, stiff movement, clinging of the canvas to the box and other incidents. And vice versa: if you hang a thick oak door on steel hinges 100 x 75 x 25 mm, then expect disaster. The hinges may not break out of the box, but they will suddenly sag.

3. “Why do you suggest buying mortise hinges for a heavy door? There are overhead “butterfly” awnings.”

No groove (groove) is made for butterflies. In fact, the door is held in place by four poor self-tapping screws on the bottom hinge. Butterflies also have a gigantic gap “out of the box”, which will only grow. In this situation, any wooden door in the 50+ kg category is doomed. It will quickly sag and begin to rub against the frame, even if it is hung by 3-4 butterflies.

4. "A door hinges hidden installation (“invisible”)? What's wrong with them?

They have a short hinge mechanism and a small fastening area, which leads to an increase in the load on the screws, and there are two of them on the side of the sash and the frame. In general, it is already clear that these are not the best hinges for thick doors (as well as for tall, wide, etc.).

Many more invisible ones narrow the opening angle. Sometimes very seriously - from 180° to 100°. You can, of course, move the box forward, as if drowning the platband in it, but this is unlikely to please your master. He already has a lot of work planned, because for hidden hinges the groove is milled not by 2-3 mm, as in the case of mortise hinges, but often by 10-11 mm or more. It would seem okay. But then we remember that we have heavy wooden doors and inside is not soft pine, but something very hard - oak, beech, ash. Such wood can be removed with a milling cutter, but it will not be so quick and easy. By the way, it won't be cheap either.

And since we're talking about money. Decent hidden door hinges (the kind that can withstand a heavy door) cost from RUB 3,000/piece.

5. “So, mortise hinges. But which ones: universal or removable?

Removable. And the point is not that with them you can remove the canvas at any time without unscrewing the screws. They have another not obvious, but extremely important advantage - simplicity. Removable hinges have only two rubbing surfaces and one support point (in the form of a hardened ball at the end).

Due to the simplicity of the design, removable hinges have less play and are not so sensitive to workmanship. Basically, if the ball rests against the cap, the hinges should and will work fine. Even if otherwise they have minor and moderate flaws in geometry.

With universal canopies on 4-5-6 bearings everything is complicated. To ensure that the bearings are evenly loaded, you need jeweler's precision casting Achieving this in the cheap segment is unrealistic: door hinges for heavy doors for 150-200 rubles they are not cast, but stamped, the axial play in them can reach 1-1.5 mm. This is already enough so that even with a perfect insertion, only one bearing plays the lead, and the rest just play along. In turn, this forces wear on the first bearing. After it is worn out, the blade will sag to the position of the next one, which from that moment will begin to work towards accelerated wear.

By the way, the removable loop has another advantage. If it sags, you can compensate for the change in height by ordering a brass or bronze washer from a turner and placing it on the axle. Universal awnings are not removable - and such a trick will not work there.

6. “How many hinges do you need for a heavy door - two or three?”

By two, except in special cases (more on this at the end of the paragraph). In this case, they should be fastened with a distance of 200 mm from the top and bottom of the canvas.

Why exactly two loops? First of all, three is almost always overkill. Let’s say you can order Palladium N 700 door hinges from us, which together can handle a 90-kilogram leaf. And 90 kg is a lot: 99% of home doors made of wood will fit into this limit.

Secondly, the third loop is needed for pressing. Its participation in load distribution is negligible, if not zero at all.

Thirdly, it is incredibly difficult to embed three hinges, aligning them along the same axis. Even if it works out, no one has canceled the seasonal fluctuations of wood, and the door will inevitably move. Because of this, the carefully set alignment will move, the load on the canopies and fasteners will become variable. Simply put, the porch will be broken, one of the hinges will begin to creak. Moreover, it is impossible to predict which one.

It makes sense to add a third loop in two cases:

Weak and thin door frame (≤ 20 mm in thickness);

High blade (≥ 2200 mm).

7. “I want to buy hinges for heavy wooden door, which will last at least 20-30 years. No creaking, jerky movement, sagging, etc. What to look for?

1.[Sideliness] This is if you listened to our recommendation and opted for removable models. How to distinguish right loop from the left, .

2.[Size] If the door is heavy (70+ kg), take higher and thicker awnings. For example, our brass hinges Palladium N 700-5″ (125 x 80 x 4 mm) – they are designed for weights up to 100 kg. If the door is moderately heavy (60-70 kg), 100 x 80 x 4 mm will do. TO interior paintings weighing 40-45 kg you can limit yourself to loops 100 (125) x 75 x 2.5 mm.

3.[Material] Steel is, at best, a B minus in geometry. Brass hinges tend to be much more accurate because they are not stamped but rather cast.

Installing hinges on the door is an important stage in the installation of the door leaf and frame. On the one side, this process does not cause any problems, since it comes down to installing the hinges themselves and securing the door leaf, but on the other hand, it requires time, as well as patience and the availability of the tools necessary for installation. Before installing door hinges with your own hands, think about whether you can achieve high quality work. It is on the correct installation of hinges and doors on them that their further operation largely depends.

Types of door hinges

Features of the installation of certain loops will depend on their type. Hinges are classified according to structural features and fastening into three main types:

• Invoices. They consist of two identical parts fastened together. One part is fixed to the door frame, the other to the leaf. There are also ones that represent a single whole. Installation of overhead hinges does not require special skills and is the simplest and most accessible to everyone.

Mortise. They are characterized by a more complex and time-consuming installation, which requires special equipment and skills to work with it. The complexity of installation is compensated widespread mortise hinges, as well as their reliability and durability.

• Screw-in. They are fastened using threaded pins - they are screwed into the door leaf, thereby securely fastening to its surface. Usually installed in the amount of three pieces per door, they differ in the number of fastening pins.

There are also hidden door hinges, which are highly complex to install, but guarantee excellent security and safety of your home.

Preparing the necessary tools

The installation process is unthinkable without a set of certain materials, tools and equipment necessary for the job. So, before starting installation you should prepare:

• door hinges.
• screwdriver and set of screws.
• pencil (necessary for marking).
• a set of wooden wedges for leveling the structure.
• building level.
• hammer and chisel.

After you have verified that the work area If you have the tools and materials listed above, you can begin installing door hinges.

Correct marking

Installing door hinges by eye is unacceptable - even a small error can lead to distortion and deformation of the door leaf and structure. Marking is done with a pencil as follows:

1. Attach the hinges to the intended installation locations. Hinges should be placed with a minimum distance of 20 centimeters from the edges of the door (top and bottom).
2. Trace the hinges attached to the door end with a pencil, then set them aside.
3. Using a chisel and hammer, make the indentations in the marked areas necessary to install the mortise hinges.

Pay close attention to the thickness of the recess. If it exceeds the thickness of the hinge, the door will rest against the frame when closing. Ultimately, this will lead to deformation of the door leaf and problems with opening and closing the door.

Before installing hinges on the door, you need to mark the door frame. This operation will require skill and patience to correctly determine the location of the loop:

1. Place the canvas in the box and secure it with wooden wedges in the way it should be in the installed state. To level the door leaf, use a building level.
2. After aligning the canvas, mark on the frame where the door hinges come into contact with the door.
3. As with the door leaf, use a hammer and chisel to make the required number of recesses for installing door hinges.

The alignment of the door leaf in the frame should be carried out not only vertically, but also horizontally. Incorrect vertical installation will cause the door to open spontaneously, and horizontal installation will make it difficult to close.

Correct installation of door hinges

Installation of mortise hinges

Inserting hinges into an interior door is the most complex procedure possible, so once you master it, you can easily install overhead and screw-in hinges. The installation procedure for mortise hinges is as follows:

1. Sink the hinges into the recesses made in the previous stages of work on the door.
2. Using a screwdriver, make holes in the wood for the hinges.
3. Take screws of suitable diameter and use a screwdriver to secure the hinges on the door leaf.
4. Install the door in doorway and secure it with wooden wedges.
5. Sink the loops into the indentations made, then repeat steps 2-3.

During installation, carefully ensure that the door is level in the frame and does not move during installation. Before hanging the door on its hinges, carefully level it in the doorway using a building level (as when marking).

Installation of overhead hinges

This is the easiest method to use and does not require insertion and preliminary preparation doors and door frame(without creating recesses). The simplicity lies in the design of such hinges and in the installation features - you don’t have to think about how to weld the hinges and secure them as firmly as possible in the socket.

Installation is similar to installing mortise hinges, however, the parts are not installed in special recesses, but are simply screwed to the end of the door and frame using screws. As in the previous case, it is important to maintain the correct position of the door leaf in space throughout the installation of the hinges.

Installation of screw-in hinges

Installation of screw-in door hinges will not cause problems even for a novice craftsman. Typically, installation involves three simple steps:

1. Before installing the hinges on the door, you need to drill holes in the door leaf using a special template, which usually comes with the hinges. Sockets for hinges are drilled both on the door and on the frame, at the same level.

1. The next step is to install the hinges in place. One half is placed on the door, the second on the frame.
2. The final stage is “stringing” door hinges onto frame hinges. This completes the simple installation of hinges.

After installation is complete, it is recommended to prevent squeaking when opening and closing doors, as well as to extend the life of door hinges. If you have any questions about correct installation door hinges, you can get additional information from the video (and also consolidate the information already obtained from this article), which can be found and played below.

During the installation of an interior door, one of the important stages is to fasten the hinges and hang the fabric on them. The fittings are selected based on your own preferences, taking into account the characteristics of the door and who will do the installation. Butterfly or card hinges are particularly easy to install and do not require scrupulous turning work to insert fittings. You will learn how to install butterfly hinges on an interior door in this article.

What are the features of this type of fittings?

Butterfly-shaped canopies structurally consist of two inseparable parts. When folded, the smaller element is nested inside the larger one. For this reason, there is no need to equip a groove to install the fittings. Fastening is carried out using ordinary hardware and does not require professional tools and skills.

Advantages of hinged hinges

Typically, butterfly hinges are used as fittings for the first attempt at installing an interior door. They are characterized by the following advantages:

• Relative strength and wear resistance. Typically, this fittings are made of stainless steel or brass and coated with a galvanic layer, which provides additional resistance to mechanical wear.
• Easy installation. The hinges do not require insertion, so inserting them does not require the help of a specialist.
• Comfort of use. The design of the fittings includes bearings that ensure smooth operation and no squeaking.
• Versatility. Suitable for left and right door mounting.
• Aesthetic appearance. Stylish and modern form loops go well with many interior styles. Wide range colors allows you to choose fittings in accordance with the shade of the door.

For hanging fabric standard sizes It is enough to purchase two loops designed for loads from 40 to 100 kg.

Disadvantages of butterfly loops

The disadvantages of card loops include:

• Their lack of reliability. Due to the fact that the fittings are located on the outside of the canvas, it is easy to dismantle for the purpose of hacking.
• Inability to screw door hinges onto a door equipped with a hinged strip around the entire perimeter.
• Not suitable for hanging techno style doors with the illusion of no fastening.

Experts identify several features of butterfly awnings that must be taken into account before installing hinges on an interior door:

• the need to accurately screw the hinges to perfectly fold the sides of the canopy to avoid unevenness of the door and problems during operation;
• frequent appearance of a small gap, which is side effect loop cards;
• impossibility of removing the door leaf without unscrewing the hardware.

Butterfly hinges are best suited for lightweight interior doors. For hanging heavy interior or entrance structures It is better to give preference to other more reliable fittings.

When analyzing the advantages and disadvantages of these products, you need to decide whether you will install a butterfly hinge or give preference to other, more suitable fittings.

How to install butterfly hinges on an interior door?

Before installing overhead fittings on the door, you need to prepare necessary tools. You will need a stationery knife, electric drill or a screwdriver, fasteners and a set of drills.

Installation diagram

The installation of this fittings begins with the marking stage. To do this you need:

• measure 200 mm from the top and bottom of the canvas and attach a loop;
• Use a pencil to mark the location of the hardware.

Further actions are performed according to the installation diagram:

• Drill holes along the marked notches, the diameter of which is slightly smaller than the corresponding indicator of the screws.
• Screw the smaller half of the overhead fittings to the end of the canvas using a screwdriver or screwdriver.
• Secure the other part of the canopy to the box. To do this, the fittings must first be fully opened, attached to the beam and the appropriate markings must be made.
• After installation, critically evaluate the quality of the work performed.

Nuances of proper installation

When fastening hardware, you should maintain the same distance between the fasteners on different parts cards. If you fasten them closer on one side and further on the opposite side, this will manifest itself in problems during operation. So that this can be corrected correct installation should be done in a safe place on the canvas, where a special wooden beam. If you drill a hole in another place, you can ruin the canvas itself. This will lead to the need complete replacement doors.

If you attach the fittings correctly, then the component fragments of the hinges should fit into one another without gaps or errors. In this case, the outer card lies flat on the end of the door leaf. If this condition is not met, it means that an error was made when installing the fittings, which will negatively affect the operation of the structure. Experts recommend eliminating the defect by placing a thin piece of cardboard under the loop.

On sale you can find canopies in which the cards are not located in a single plane, but have a discrepancy between the inner and outer parts of 1 mm. Their operation differs in convenience, and installation is carried out according to the same method described earlier.

What to do if a defect was detected in the operation of the butterfly loop?

The butterfly hinge has such a simple and laconic design that it is ideal for installation by a novice craftsman. As a rule, with a lack or complete lack of experience in carpentry, some errors in installation occur. You may not notice them right away, but soon during the operation of the structure they will manifest themselves in creaking, spontaneous opening of the door, or, on the contrary, in difficulty closing the door. Experienced craftsmen They claim that every defect can be corrected with your own hands.

Identified defect in the operation of the door		Fixes
The door creaks when in use, opens spontaneously, the hinges and door lining wear out quickly	The wings of the hinges do not fit tightly to the end or to the door frame. Most likely, there are excess gaps and the loop is “walking”	The defect is corrected by placing a small piece of cardboard so that the free part of the loop fits tightly to the surface of the canvas or box
The door does not close completely during operation	It is necessary to replace hinges in which the wings are not located in a single plane	Old fittings are replaced with awnings of a suitable type. Another way is to place a small piece of cardboard with inside designs.
Unable to close the door tightly	Top hinge sagging. At the stage of preparation for installation, the correct gap (larger in size) was not provided on the side of the lock	The problem is most often identified at the final stage of installation of the canvas and box, when a change can harm the appearance of the product. The solution is to embed the external card into the door frame.

Conclusions

It is best to install overhead awnings on light ones interior doors, the functions of which do not have increased requirements. They are very decorative and easy to install, but are not able to withstand a massive structure and last a long time in conditions of increased wear and tear. For entrance and heavy doors, it is recommended to choose fittings that are more resistant to wear and tear.

Installation of the door and door frame is a mandatory stage of repair in own home. In particular, the structure will need to be hung on hinges. To do everything with your own hands efficiently, read the instructions and select your preferred technology. Inserting hinges is not a complicated process, but first you need to familiarize yourself with its details.

Attention! More often the door is hung on two hinges. However, this is only suitable for lightweight canvases made from MDF, plastic or chipboard. For door leaves from natural wood or heavy materials, three sheds are required. This will eliminate sagging and guarantee proper quality of operation.

Overhead hinges as the most versatile option

Professional method and application features

Many people prefer the professional method, the advantage of which is the speed and ease of implementation. This method is often used by professional workers to ensure quick installation.

Such work requires the availability of appropriate tools. First, you will need a manual milling machine. It is used to create a clean cut. Also, arm yourself in advance with tools that will allow you to perform the insertion itself. This tool involves a kind of overlay, the task of which is to prevent damage to the door leaf.

You will need tools that will allow you to maintain the dimensions for the awnings. This will simplify the installation process. Equipment that helps create a groove both on the box and on the canvas. This allows you to connect two parts of the door frame together. The result is that there is no need to use matching groove joints.

If such tools are not available, since they are professional equipment, do not be discouraged. It will be possible to get the job done with the help of milling machine. No specialized skills are required for this. You can learn how to use the device while using it. The disadvantage in this case is the need for a large amount of time.

Treat the mechanism itself carefully. This will prevent scratches on the canvas. The appearance of the door structure will remain unchanged. Coating the milling machine with a special coating will help with this. protective material. You can give preference to felt.

Various options loops

The artisanal method and its main features

The artisanal method is also in demand, but its difference is the low result when compared with the previous option. To complete the installation, prepare a hammer and chisel. No other tools are needed, which is convenient for DIY installation.

Be aware of the possibility of sloppy edges when installing hinges for laminated panels. The operating principle involves the following steps:

• Marking for installation of the groove. To do this, the element is placed in its position and circled. In this case, you should act seriously, achieving accurate markings.
• Edging the connection of the grooves. Use a chisel and hammer. The edging must correspond to the markings.
• Sampling of the groove connection. A chisel is used for this. It is mounted at a certain slope, and the recess itself is knocked out with a hammer.

As a result, all that remains is to place the loops in the resulting holes and secure them. To get rid of any spots or roughness that appear, use the staining method. This will exclude external negative manifestations self-installation and significantly improve appearance.

Hidden hinges on interior doors

How to put a door on its hinges yourself?

If you have no experience inserting hinges, look for other universal and simple ways. They are based on the use of canopies, which eliminate the need for special grooves. There are two methods of such installation. The first involves the use of special hinges without inserts.

Their installation is simple, because there is no need for insertion. It is enough to install the hinges on the door itself and the door frame by screwing. They are installed on top of each other closed door. Due to the fact that the thickness is about 0.25 cm, a technological gap may form. A significant drawback is the lack of aesthetic appearance.

The second method, which involves the use of screw-in hinges, is also becoming relevant. In this case, the grooves are replaced with ordinary holes, the creation of which will not be a problem for any person. Each of the three hinges requires two holes on the frame and one in the door itself. Externally, such loops look interesting and attractive.

Last possible option, which can easily replace the creation of grooves, is the use of pin hinges. They are cut into the canvas itself. At the same time distinctive feature becomes the design of the product, hiding the installation site. The result is an attractive appearance of the structure. The loop will be noticeable only in the position open door. This is due to the fact that it is represented by two plates, which are installed at the bottom and upper parts doors.

Hidden hinges and necessary fasteners

What to do if the door is made of metal?

All of the above methods are effective for ordinary door designs- made of wood or its analogues. For a metal door you will have to look for alternatives. These include welding hinges, which will result in convenient and silent opening. You can do everything yourself if you listen to the instructions.

Initially prepare a number of tools:

1. Locksmith's hammer.
2. Records.
3. Welding.
4. Bulgarians.
5. Steel door hinges.
6. Electrodes.
7. Special protective clothing, as well as gloves and masks.

Loops on metal doors

Attention! Using plates is a great way to make the welding process as easy as possible for those people who have not previously encountered it. It will help to check the correctness of the installation laser level. With its help, the installation location of subsequent loops is determined after one of them has already been welded.

The three hinges on metal doors are cylindrical or hexagonal in shape. The first option is easy to install and is based on the use of plates. The work is carried out outdoors, with the door laid horizontally. The plate is selected so that it matches the size of the loop. Before starting welding, check the accuracy of the markings. To do this, the door is installed vertically.
