Types of interior door hinges

All types of doors perform 2 functions: protecting the entrance and decorating the space. Therefore, when choosing, it is necessary to rely on the reliability of the design and on its aesthetic appearance.

The appearance of the door should be in harmony with other interior details. Not the last place in this is occupied by door hinges. Errors in their selection end with canvas distortions, poor-quality work of the entire structure, and a spoiled opening.

Varieties of loops

There are several classifications of door hinges. Classifications can be based on:

• material
• fastening method
• design
• mechanism features
• attachment point

If doors made of steel and plastic are supplied in a complete set, which includes awnings, then for doors made of MDF and wood, you need to buy hinges yourself. Therefore, all the characteristics and tips below will apply exclusively to doors of this type.

What are the types of loops at the installation site

Since the doors are both entrance and interior, the types of door hinges for each case will vary.

For entrance groups, more massive hinges are produced; they are designed to be used in conjunction with heavy entrance doors. Their difference is not only in size. Entrance door hinges have a special sash resistance mechanism, which eliminates the possibility of lifting the leaf. This device consists of depressions and protrusions, which, combined in the closed position, do not allow the canvas to move up / down after being aligned with the box.

We also consider the subsequent choice of loops.

Features of detachable and universal hinges

Detachable hinges are sometimes called removable or canopies. Their difference is that the canvas, suspended in this way, is removed without dismantling the loop. From the figure you can get acquainted with how the detachable loop mechanism works. Both elements of such a device have their own names, which folk wisdom gave them. Now the words "dad" and "mother" have become generally accepted, they are used by both ordinary people and professionals.

Universal hinges are one-piece. To remove the canvas, fixed with the help of such a mechanism, the loop must be unscrewed. Universal models are used on doors that open both inwards and outwards. However, the need to unscrew all fasteners when it is necessary to remove the canvas is considered by many to be inconvenient.

1. Frame wing, has three hinges; 2. Sleeve; 3. Door fender, has two hinges; 4. Self-tapping screws for fastening

Types of loops depending on the design features

There are several types of loop design. Among them are the following:

• mortise;
• screw;
• invoices;
• hidden;
• corner;
• bilateral.

Below is a description of structures of all types.

Overhead/mortise hinges

GOST 5088-2005 regulates the requirements for overhead and mortise hinges. In this document, there are practically no fundamental differences between these two types of structures. The fact is that the main part of the mechanism they have the same. This can be seen from the figure below.

Both of these types have card-type loops. One is attached to the canvas, the other to the box. However, the opening and the canvas for each of these types are prepared in their own way.

• overhead view is attached immediately to the surface;
• for mounting the mortise variety, recesses are made into which card loops are placed.

The history of overhead loops has more than one century. In ancient times, overhead door hinges were forged from steel strips. The symmetrical shape was not the goal of the blacksmiths' work. They strove for diversity, ornate forms and, of course, strength. The dimensions of those ancient hinges were much larger than modern ones. Each product was unique, bearing the imprint of the style of the master who forged it.

Today, when recreating the retro style, designers also design door hinges, repeating the rules and traditions of manufacturing this part of the door structure that have gone into the past. For the manufacture of these details, designers turn to the masters of artistic forging.

The popularity of overhead hinges is associated with the ease and high speed of their installation. The plates are screwed with screws, after which the door is installed in the opening. Physical and time costs are minimized. In recent years, such a variety of overhead models as butterfly door hinges has been gaining popularity. The special shape of the cutout, which looks like a butterfly wing, allows the mechanism to be folded so that the thickness of the product corresponds to one half. Under such a loop, no cutouts are made either on the box or on the canvas.

In terms of their properties, mortise models are in many ways reminiscent of overhead models. Only for their installation it is necessary to make a cutout for the hinge plate. Recesses are made both on the box and on the canvas, namely in its end part. Screw this product with screws. When the door, hung on mortise hinges, is in the closed position, only the pivot pin can be seen from the outside.

Each of the above types of loops is divided into detachable and universal.

If we compare overhead detachable models and universal ones, it should be noted that the universal door hinge has a stronger and more rigid design. Therefore, even with small sizes, these devices cope with fairly large loads. By choosing this type, you protect the door structure from subsequent sagging.

Overhead detachable loops are right-handed and left-handed. You need to be careful when buying, so as not to make a mistake. In the case of universal models, this is not to be feared. There are no restrictions on the opening side of the sash.

Screw-in (screw-in) hinges

Screw hinges are devices consisting of 2 parts having the shape of a cylinder. The constituent parts are arranged symmetrically with respect to each other. The product is equipped with holes for fasteners. One "barrel" is mounted to the canvas, the other - to the box. Screwed loops are considered universal because there are no right and left elements. The main property of screw-in hinges is the solidity of fastening. There is no way to remove such a door from its hinges. Perhaps this is not only an advantage, but also a significant disadvantage. But many, precisely because of this property, acquire loops of a similar design.

Advice! If there is a desire to purchase screw hinges, you need to get a canvas with a quarter, which is usually called a euro canvas. Otherwise, they simply cannot be fixed.

Angle hinges

The corner loop can be distinguished from other analogues by the method of attaching the axial rod. There are no standard wings fixed near the rod, which occupies a central position. In this case, profile corners will be attached to it. In fact, these are the same card sheds, only having the shape of an angle. This form gives them some advantages, for example, the ability to mount hinges on rebate doors.

Angle door hinges for doors with a porch are fastened in the same way as mortise door hinges. One corner is deepened into the end of the door, fastened to the screws. The main disadvantage of this design is that the device is clearly visible, not hidden in any way.

Hidden loops

Hidden loops are not afraid of picky looks. They are almost invisible when the door is in the closed position. This fact gives aesthetics to the whole appearance of the door, so this mount is considered elite and is in great demand. Ease of use is facilitated by the absence of the need to distinguish between right / left hinges during installation.

Hidden door hinges have 3 rotary axes and are not easy to install. Therefore, not everyone can cope with such a thing on their own. If it is decided to install hidden hinges, it is recommended to use the services of professionals.

double sided hinges

Double-sided loops are essentially the same awnings-cards. The main property of these mechanisms is to ensure the operation of the door leaf in 2 directions. On these hinges, the door leaf will move both forward and backward. Such a function in the living space is not in demand. Therefore, double-sided hinges are not installed in apartments. But in public institutions - quite often, especially on the doors of the entrance group.

Varieties of models by material and type of coating

Steel products never go out of fashion. In the past, blacksmiths were famous for their ability to make a wide variety of things out of steel, including sheds for doors. Today, for doors that are operated indoors or at the entrance, alloy hinges are used. Most often, aluminum and brass alloys are taken for this. Steel is used for custom-made artistic forging products. In the Soviet years, loops were an ordinary type of product, all products were the same, unattractive. In the production of hinges, no protective or decorative coatings were used. Therefore, the loops had to be painted with conventional paints and varnishes before being used together with the canvases.

Today, "Soviet" type awnings are installed in utility rooms, on the street. In apartments and houses, stainless steel hinges or forged products are installed, stylized "antique".

Stainless steel products have a number of time-tested advantages:

• high strength;
• durability;
• resistance to temperature fluctuations;
• the ability to contact with moisture without changing the quality.

Door hinges are available in a variety of designs and colors. Color variations are achieved through the use of a variety of coatings. For this, enamels and special compositions are used. As a result, loops with the color “under gold” or “under bronze” are obtained. There are chrome-plated products, brass-plated and some others.

Hinges are made of alloys of aluminum, zinc, steel, copper. In the course of production, coatings are applied to the products that protect the mechanisms from corrosion, giving a modern attractive appearance. This makes it possible to choose the option that best matches the design of the room, match the color and style of the canopies with other elements of fittings and decor used in the space.

The world's leading manufacturers avoid brass coatings. They make them entirely from this material. This eliminates the problem of abrasion, they look great after polishing, they last a very long time. Brass hinges are considered as strong and reliable as steel devices. However, their price is quite high, so not everyone can afford to buy them.

Before buying, you need to make sure that the product is not counterfeit. Fakes serve little, quickly lose their appearance, and in a short time lead to sagging of door panels. This is due to the materials that go into their manufacture. They can suddenly collapse, as a result of which the canvas can fall and injure people around.
