Application of hidden hinges for interior doors. Features of installing hidden hinges for interior doors

Sections of the article:

Interior and entrance doors should not only reliably protect the house from the penetration of unwanted guests, but also please the eye with their appearance, have performance characteristics corresponding to their purpose.

When choosing and decorating a house design, hinges for doors play a huge role, since their unsuccessful selection can ruin not only the door leaf, but also the entire interior of the home.

Also, bad hinges can lead to subsidence or skewing of the canvas, loose fit of the doors to the door frame, and unpleasant squeaks.

Loop classification

The choice of hinges on the door is huge and is represented by products from hundreds of manufacturers, which are divided according to the following fundamental characteristics:

  • Installation site;
  • The principle of the connector;
  • The method of fastening to the box;
  • Manufacturing material;
  • Type and design features.

At the same time, it is necessary to clarify that the choice of hinges is only needed for interior and entrance doors made of MDF or wood. Doors made of other materials, as a rule, are equipped with awnings and appropriate fittings by the manufacturer and are included in the delivery set.

Types of hinges by installation method

Depending on where the doors will be installed and what their purpose is, the hinges are divided into two types:

  • For interior doors;
  • For entrance doors.

Since the entrance doors differ from the interior doors by their significantly greater weight and massiveness, the hinges for them are somewhat larger than their interior counterparts. The main design feature of the door hardware is that the hinges are equipped with a special anti-removable mechanism that prevents intruders from lifting and removing the front door.

It is for this purpose that depressions and protrusions are arranged on their wings, which are combined when the sash is closed and do not allow the door to rise even under the pressure of an improvised tool.

Universal and split hinges

Such types of simple hinges for doors as split hinges allow you to raise and remove the sash without having to unscrew the fastener. For a long time, removable hinges have been called "awnings" by the people, this name has firmly entered into use.

The awning design consists of two parts, cleverly called "dad" and "mom", a term used by many professionals and users in some countries.

Universal hinges for interior doors will have to be unscrewed if there is a need to remove the sash. They are suitable for door structures that open both outward and inward, which can be considered a definite plus. However, the need to unscrew the fasteners causes certain inconveniences and loss of time, which should be attributed to the fat minuses.

Separation of hinges by type of construction

According to their design features, door hinges are divided into the following types:

  • Mortise;
  • Screw-in;
  • Overhead;
  • Corner;
  • Double-sided;
  • Secret.

Each type of design has its own disadvantages and advantages and deserves separate consideration.

Overhead and mortise

The main structural elements of the mortise and overhead hinges are completely identical.

Both types are card hinges that are fixed both on the box and on the door leaf. The difference lies only in the method of carrying out preparatory work: overhead hinges for interior doors do not require special surface preparation, while for mortise hinges in the box and at the end of the canvas, small recesses are arranged in which the card plate is recessed.

Overhead hinges have been used since ancient times. They were made of steel - skilled blacksmiths received a durable and beautiful product, albeit not differing in the symmetry of modern hinges. The hinges were reliable and large enough.

Nowadays, design solutions in the production of overhead hinges again return to the unforgettable retro style. They are increasingly being made "semi-antique" and find a place for themselves both in private country houses and in apartments.

When choosing overhead hinges as a door fastener, first of all, attention is paid to the simplicity of their design and installation - the hinges are simply fastened to the screws, and the door is inserted into the frame using improvised means without using any ingenious devices.

An interesting design idea for a traditional and conservative flat card is considered to be such a type of patch loops as the butterfly loop. It folds down to the thickness of a regular card thanks to an intricately designed butterfly-shaped cutout. For such hinges, it is not necessary to perform a selection either in the box or in the body of the sash.

Mortise hinges in their design and method of attachment are completely identical to overhead hinges. The only difference is that they cut into the end of the installed door and are fixed with screws. When the door is in the closed position, only parts of the plates covering the pivot axis are slightly visible.

In addition to the division into "with a tie-in" and "without a tie-in", overhead and mortise hinges on the door can also be universal and detachable.

Traditionally, removable mortise hinges are called mortise canopies, and universal hinges are called mortise hinges.

The main difference between detachable overhead hinges and universal ones is the increased rigidity of the structure of the universal hinge, which allows it, with significantly smaller dimensions, to withstand a large applied load, while sagging of the sash in the opening is always minimal or absent altogether.

Another difference between such modifications of overhead hinges can be called the division of canopies that are detachable according to the opening method into left- and right-sided. Universal hinges are not divided according to this principle - there is no difference in their installation to open the door.

Screw-in (screw-in) hinges

The design of the screw-in hinges consists of two symmetrically located parts, in the form of cylinders, in which holes are made for screws. "Kegs", as they are popularly called, are considered analogous to flat cards in terms of their functionality. One wing of a cylindrical shape is fixed by means of screws on the door leaf, and the other - on the frame.

Loop screw mechanisms are universal, that is, there is no need to select hinges on the right or left side. A feature of such hinges can be called the fact that after installation it will be impossible to remove the door - this is both an advantage and a disadvantage of screw hinges. Screw-in hinges are allowed to be used only on doors with a quarter (euro-plate), the door leaf, made according to domestic standards, is not suitable for fixing on such awnings.

Corner hinges

The main external difference between such hinges and mortise or overhead loops is the fastening on the axial rod not of a simple pair of flat wing-plates, but of a pair of profile corners. This form of cards is mainly mounted on rebated doors.

Fastening at the end of the door is carried out by a mortise method by means of screws, and the hinges themselves, although conveniently placed in the opening, are easily visible against the background of the door structure.

Concealed hinges for interior doors deserve special mention largely due to their aesthetic characteristics - when the door is in the closed position, the awnings are not at all noticeable. They, like screw-in hinges, are universal, which can be attributed to another advantage of this type of awning.

The design feature of the hidden hinges is the presence of at least three pivot axes. Secret hinges are not easy to install, therefore it is better to use the services of specialists to install the door.

Double-sided hinges allow the door leaves to open freely both in one direction and in the other.

The main application of such hinges was found in office doors; they are rarely installed in interior apartment doors - they are simply not needed there.

Classification of loops by material of manufacture

The materials for making hinges on the door do not differ in a wide variety.

Recently forgotten steel products are gradually regaining their leading position. For many years, blacksmiths have been improving the technology for making hinges from pure steel, but the development of aluminum-alloy industries pushed this material back for some time. During the Soviet era, steel hinges were used in our country mainly for the production of ordinary consumer goods without any special frills and aesthetic qualities, without any anti-corrosion or decorative coating.

Nowadays, the installation of simple steel canopies on interior doors is unpopular, they are used mainly for street and garden gates, they are installed on doors in non-residential premises. The apartments are now equipped with forged door fittings, stylized "antique" or stainless steel hinges.

The main advantage of steel canopies is the highest mechanical strength and abrasion resistance. Stainless steel awnings are also highly resistant to moisture, temperature extremes, and therefore they are actively used for hanging entrance doors facing the street.

Thanks to the development of design ideas and the improvement of technologies, enameled hinges or coated with special chemical compounds "like bronze" or "like gold", brass, chrome-plated are widespread. Alloys of copper, steel, aluminum or zinc are used as the main material, which are subsequently coated with special compounds for decorative or anti-corrosion purposes.

The world's leading manufacturers of door fittings prefer to manufacture hinges entirely from brass rather than spray-coating them. This is especially true for elite and expensive models. Such awnings are capable of retaining their decorative and aesthetic properties for a long time, and in terms of wear resistance and strength, products made of brass are in no way inferior to steel ones.

Folding door hinges

Folding interior doors have entered the interior of our apartments relatively recently. Normal operation of doors of such a design, consisting of separate sections, is ensured by special fittings included in the kit.

Hinges for folding interior doors are mainly used for mortise, special design. Their purpose is to connect the sashes, of which there can be several, from above and below.

Each type of door uses its own type of fittings, the quality of which affects not only the appearance, but also the service life of the door.

They act as supporting mechanisms to ensure their successful opening and closing. The modern market presents hinges in a wide and varied assortment. Hidden hinges stand out among them for their aesthetics and functionality: thanks to their design, they provide 180 degree opening of the sash and are not striking.

About the device of hidden fastening systems

Hidden hinges are made of a special alloy of aluminum, magnesium, zinc and copper, which is harmless to human health, which is called tsamak. of this alloy are distinguished by high strength and a smooth surface with a glossy or matte finish, due to the application of brass and nickel plating to it.

An important element of invisible fastening systems is the hinge, which is connected to the canvas by means of a lever divided into two parts and fastened by a common screw. It remains invisible, as it is recessed in a metal case, which is equipped with hidden hinges.

Drawings of hidden fastening systems are presented below.

Design features

  • The movable canvas ensures ease of opening and closing.
  • Hidden hinges are equipped with reliable fastening, which excludes spontaneous disconnection of the sash from and increases the operational life of the fastening mechanism. Interior doors equipped with them are able to withstand the cycle of opening and closing up to 200,000 times.
  • The design allows you to fix not only the extreme positions of the web, but also, if necessary, intermediate ones.

Mounting

  • With an electric milling cutter, recesses are made in the door and the frame of the box;
  • choose strips for fastening;
  • unscrew the fastening screw on the lever and divide the components in two;
  • insert the hinged parts into place and fasten them with self-tapping screws;
  • parts of the lever are connected and tightened with a fastening screw;
  • covered with decorative inserts.

Advantages

Hidden hinges have advantages that make them widely popular with consumers:

  • the presence of uniform gaps on the four ends;
  • the secrecy of the entire system, providing a high level of aesthetics;
  • guaranteed protection against the penetration of intruders, by eliminating the possibility of access to the loop in order to damage it;
  • increasing the angle of the door being opened, which is important if it is necessary to move large furniture through the door;
  • reliability of the structure, which prevents the door leaf from sagging, which ensures an increase in the service life of both the hinges themselves and the entire door system.

disadvantages

  • The price is much higher than the cost of conventional hinges.
  • Quite complicated installation. Invisible awnings are the last thing to be installed during renovations. This is due to the fact that there is a risk of dust or small construction debris falling on the surface of the loops, which will negatively affect their further operation. If dust does get onto the hidden hinge mechanism, it must be removed immediately with a vacuum cleaner.

About buying hidden hinges

The modern market offers a large selection of different concealed hinges to support any weight. Some products are designed for high force impact (up to 200 kg), others are focused on light weight (not exceeding 50 kg). Accordingly, their prices are different. The stronger the mechanism, the more expensive it is. Therefore, it is important for the buyer to take into account the weight of the door when choosing hidden hinges for it.

Photos of the fastening mechanisms confirm that for each door model you can choose the fittings option that suits the owner.

For example, if the door structure merges with the wall, hidden hinges are ideal for it. Reviews testify to the effectiveness of the installation of hidden fastening systems, which ensure their invisibility, which means that the level of aesthetics of the doors increases.

Before purchasing the necessary fastening mechanism, it is important to consider the direction of opening, depending on which hinges are left, right and universal (such that they are mounted on either side of the door frame).

The correct choice and arrangement of hinges will ensure the proper level of comfort and durability of the door system.

In the houses of modern people, almost any doors work due to the presence of door hinges, of which there are many types: overhead, corner, mortise and secret hinges. Which one to give preference when choosing?

What are the advantages of such loops

Concealed door hinges are visually attractive and completely safe door hardware, which has many advantages, as indicated below:

  • High level of security. Due to the special design and type of fastening (inside the door leaf), hidden hinges cannot be opened (hacked or cut down) by intruders from the outside of the door, unlike other door hinges.
  • Absolute reliability. Countersunk hinges are made of durable metal alloys and differ in the simplest design, which is why they can serve for several decades, provided.
  • Decent power. Concealed hinges can support a lot of weight, so they can be installed not only on interior doors, but also on steel entrance doors.
  • Nice appearance. It is known that hidden hinges are placed inside the door leaf, and that is why they do not spoil the appearance of the door from the outside.

Thus, hidden door hinges are a good choice for any home if you purchase a quality kit. Now you will find out how to do this correctly.

Basic rules for making the right choice

In order to choose the right and high-quality concealed hinges for doors, you need to look not only at the cost of the kit, but also at its characteristics. It is often possible to buy a really good kit at an average price, while the most expensive and rated hinges will not be able to meet your safety requirements. Be objective when choosing hinges!

Another unspoken rule is to trust only proven products. Below in this article you can familiarize yourself with the manufacturers of high-quality and reliable hidden hinges. You should not make a choice in favor of kits of suspicious origin, because you are choosing not just door hinges, but your own protection. This also applies to the option if you choose furniture hinges - there should always be quality.

Instructions for the selection of loops

There is no strict instruction by which you can choose hidden hinges for interior doors (and any others). Despite this, you can give an algorithm of actions, following which will set you on the right path and help you get closer to the right choice:

  1. Determine which way your door will open. To do this, stand facing the door and grab the handle. Pull towards you - if you open the door with your right hand towards yourself, and it opens to the right, then the hinges must be chosen on the right. Otherwise, you need to purchase a set of left hidden door hinges.
  2. Find out which buttonhole size you need. It is easy to determine, knowing the approximate weight of the door leaf: for doors from 10 to 25 kilograms, hinges with a height of 7-8 cm are suitable, doors from 25 to 40 kilograms will hold well on hinges 10 cm high, while heavier sashes must be placed on secret hinges even longer.
  3. Determine the required number of loops. Installation options will also depend on the weight of the doors - light ones can be put on two hinges, and heavy ones - on three or more hinges.
  4. Choose good material. Concealed hinges for metal doors are made of brass (resistant to corrosion), steel (high strength) and brass-zinc alloy, which is distinguished by both high strength and resistance to corrosion.

If your goal is versatility, choose brass-zinc alloy concealed hinges. You may have to spend more money on a set of such loops, but you will protect yourself from premature destruction of the loops and the loss of the necessary safety.

To install hidden hinges, you will have to make deep slots in the door, so before purchasing a set of hinges, make sure that they can be installed in your door.

Internal hinges have a wide range of applications. They are installed on various types of doors and furniture facades. Furniture internal hinges, as well as door hinges, have a significant advantage - they do not spoil the appearance of a door or a piece of furniture. How to select and install hinges of this type, read on.

Types of inner loops

The main classification of internal hinges is their division by purpose. Allocate:


  • internal garage hinges and hinges used to install gates and wickets. Simple cylinder hinges can be reinforced with small metal plates.

All hinges can be subdivided according to their overall dimensions, which are selected based on the weight of the door leaf or furniture facade.

Advantages and disadvantages of inner hinges

The main positive qualities of the inner loop are:

  • lack of visibility of the hinges when the door is closed;
  • inability to access the hinges from the outside of the door;
  • protection of fittings from the effects of atmospheric precipitation (with the exception of hinges installed on gates and wickets).

The disadvantages of this type of hinge are:

  • higher cost;
  • the complexity of the installation;
  • limiting the opening angle of the door.

Installation of hinges of various types

The installation methods for hinges for gates, doors and furniture fronts are somewhat different from each other. Let's consider each method in more detail.

Installation of internal hinges on furniture facades is carried out according to the general scheme shown in the figure.


In order not to make numerous measurements and calculate the location of the constituent elements of the hinge, a template can be used during installation.


  1. installation of the main part of the hinge, equipped with a cup;

  1. installation of a striker;
  2. the final stage is the adjustment of the buttonhole, which can be done in three directions.

Door hinge installation

To install internal door hinges, you need:

  1. mark the hinge installation area on the side of the door leaf and door frame. For the convenience and speed of marking, you can use specialized;

The optimal place for installing the hinge is considered to be an area located at a distance of 15-20 cm from the upper and lower edges of the door leaf and frame.

  1. in the door leaf, using a milling machine (in the absence of a device with a hammer and a chisel), a part of the tree is removed to arrange a recess. If the installation is carried out on a metal door, then the hinge is located between the door leaf and the skin;

  1. a drill drills holes for fastening bolts;
  2. the loop is fixed and, if necessary, it is made.

Additionally, you can watch a video on the correct installation of internal hinges on an interior door.

Installation of the hinge on the gate

To install the internal hinges with your own hands on, you will need a welding machine, since the connection of the hinge and the metal surface of the gate (wicket, support pillars, etc.) is considered unreliable.

Installation when using welding is done in the following way:

  1. places for the installation of loops are selected. The number and dimensions of the hinge are calculated based on the weight and overall dimensions of the doors. If installation of two hinges is required, then they are located above and below at a distance of 15-20 cm. The third and subsequent hinges are mounted evenly in the space between the two extreme ones;

For doors weighing no more than 30 kg, additional hinges are not required.

  1. inner steel hinges consist of two parts connected by a pin. First of all, a part of the hinge is welded, intended for installation on a gate or wicket. The weld seam should be located along the entire length of contact between the hinge and the front of the door;

  1. the correct opening of the gate wing (wicket door) is checked. Deficiencies are eliminated by acting on the loop with a hammer;

All loops must be in the same line and in the same plane.

  1. the second part of the hinge is welded onto the support post or the metal frame of the gate (depending on where the hinge is installed);
  2. the two parts of the hinge are connected by simply hanging one part on the pin of the other component;
  3. welded seams are leveled and cleaned before further processing.

The choice of hinges for installation is made on the basis of its purpose, since furniture, door and gate hinges differ significantly from each other. Installation of various types of loops is done by hand with the simplest tools and knowledge gained.

It's no secret that all doors are opened and closed thanks to a small but irreplaceable mechanism - door hinges. Since, in addition to this, they also hold the sash itself, the service life of the entire structure depends on the correct choice of this type of fittings.

Door hinges are an integral part of the door. Thanks to them, the sashes rotate relative to the ends of the box. However, in terms of aesthetics, it is better to install hidden models on interior doors. Thanks to the functional capabilities of these products, the sashes swing open 180 degrees, while the awnings themselves are not visible.

Appearance

Constructive characteristics of hidden canopies

Door hinges must meet the following requirements:

  • easy movement of the canvas (open, close);
  • durable fastening for the entire service life;
  • the impossibility of spontaneous separation of the canvas from the box;
  • trouble-free operation for the entire warranty period;
  • fixing the extreme positions of the canvases.

Many firms and companies specialize in the manufacture and sale of excellent quality hidden hinges for interior doors. Such structures are capable of withstanding up to 200,000 opening and closing cycles.

The material from which the hidden loops are made is called tsamak. It is an alloy of aluminum, zinc, copper and magnesium. Tsamak is safe for people and animals, it can be easily cast even at low melting temperatures. The alloy is durable, with a smooth surface. The color scheme is uniform, therefore, after production, bronze and other coatings (nickel-plated, chrome-plated or brass) are applied to the hidden hinges, due to which they acquire a specific shade, matte or glossy surface.


Hinge color options

The design of the hidden door hinge is based on a hinge located in the body. The connection to the door body is via a lever consisting of two bolted elements. During the slamming of the doors, the lever enters the grooves, and it is impossible to see it from the outside.

When choosing canopies for interior doors with hidden hinges, pay attention to the direction of opening of the sashes, since they are left-sided, right-sided and universal. Hinges can be installed on either side of the door frame.

Advantages of a concealed door hinge

The indisputable advantages of hidden loops include the following:

  • wide opening angle (180⁰), which makes it easier to carry oversized pieces of furniture or appliances;
  • adjustment is carried out without dismantling the sash;
  • the hidden hinge mechanism ensures the same adhesion of the canvas to the frame, thanks to which the gaps on all sides will be equal;
  • strength and durability of the structure;
  • hidden installation is one of the important aspects that allows you to introduce new aesthetic requirements into the design of an interior door;
  • auxiliary protection against penetration - due to the hidden location of the hinges, attempts to cut or knock them down are excluded;
  • the canvas with such loops does not sag.

How hidden elements are installed

When choosing a hidden model, take into account the weight of the door leaf, which plays an important role in the future of the awnings. Some are designed for 200 kg, while others for only 40. Products are mounted in boxes made of wood, metal or aluminum.

Invisible models are installed in folded and unrebated casement structures. For doors that must merge with the wall, the installation of just such fasteners is required. Only in this case they will remain invisible.

So how do you install hidden awnings? If you decide to install the mounts yourself, take your time and think it over carefully. For installation, you will need special tools that you are unlikely to find at home. Therefore, it is better to ask a professional to do it. If you are determined to do everything yourself, then first carefully study the drawings and installation instructions.


Self-insertion

The hinges are mounted at the end of the doorframe from the jamb and into the door frame by means of a tie-in, after which they are fixed with self-tapping screws. To cut into the door frame, a two-level recess is drilled. To do this, you need an electric milling cutter with templates. One chisel is not enough here. The templates are included with the fasteners. If they were not there, then you will have to make it yourself, having made a preliminary drawing.

The indentation depth varies for each model. This also needs to be taken into account. When performing installation, accuracy is needed, otherwise gaps will appear when the door is closed.

If you need to install hidden models on a metal door leaf, look for specially designed massive awnings. They securely attach the sash to the frame and support the heavy weight of the structure. Due to the fact that it is problematic to make holes for hidden products in a metal door yourself, they are sold in advance already equipped with special fittings and cutouts. So pay attention to this when buying.

Adjusting metal door fasteners

In a normal situation, three sets of fasteners are installed on the sash, which will allow you to enjoy the reliability and durability of the structure for a long time.
