Door hinges hidden: how to choose and install correctly

Despite the growing popularity of folding and sliding canvases, swing doors - or as they are called: doors with a vestibule, are still out of competition. The hinges are their integral part, since they take all the loads and ensure the rotation of the valves.

Door hinges for concealed installation - this is just one of the constructive types of bearing fittings. We will talk about their merits and varieties, as well as present the video in this article that will help you to install and adjust the loop with your own hands.

Requirements for door hinges

First of all, the hinges must withstand mechanical loads, and therefore the standard provides for their separation, depending on the weight of the door leaf. On this basis, they are divided into three categories: for valves weighing up to 60kg; for cloths up to 120kg; massive doors weighing up to 250kg. Heavier door blocks are already special products, and for them hinges are constructed separately.

So:

• Door hinges can be mortise or screw-in, but there are also combined options. They can also be left or right opening, or have a universal design. Regardless of the type, the hinges must have sufficient strength to hold the sash in a predetermined position, as well as to provide, if necessary, the possibility of repair or replacement.
• The loop configuration should be such that its attachment to the frame and the canvas is as reliable as possible. In this case, the movable element, which is called the map, must rotate around the axis of the loop without jamming. Most manufacturers, following the recommendations of the state standard, use bearings for this purpose.

• The quality hinges that you see in the photo should ensure the opening of the cloths at least 200,000 times, and if this is the entrance door, then 500,000 times during its service life. Their resistance to dynamic and static loads in the finished block is determined taking into account design features and material of manufacture.
• Hidden door hinge has a high aesthetic, and this is another advantage of this product. For this reason, these fittings are placed not only on the entrance doors, but also on interior and other interior canvases. Such hinges can be made of steel, aluminum, various alloys, hard plastic - it all depends on the type of door.
• If the material from which they are made does not have corrosion resistance - such as steel, for example, then their parts should have a decorative protective coating. So, the price of products consists not only of the size of the loops, but also the complexity of their design, as well as the quality of the face layer.

They are supplied in complete hinges, with a full set of elements and fasteners necessary for installation and subsequent operation. According to the current rules, the installation manual must be present in each box with hinges, and at retail, the corresponding label is attached to them.

Criteria for selecting loops hidden type

The "invisible" loop is the body in which the hinge is hidden, which is connected to the web by means of a lever. It consists of two elements, fixed between a screw. When the door closes, the lever is hidden in a special recess, and therefore it is not visible from the outside.

So:

• When buying loops should pay attention to their execution. If the products are not universal, then, naturally, you need to correlate them with the option of opening the canvas: left or right. Door hinges for flush mounting may or may not have adjustment - as a rule, such a possibility is not provided in budget models.
• Of course, everyone chooses on their own, but it is worth noting that this is not the case when you need to save. Special attention to the hinges with adjustment should be paid to those who install the doors in new buildings.

• In the first two or three years, the building shrinks: this applies to both apartment and private houses. We think many have come across such a situation, when a new door suddenly - for no reason at all, ceases to close normally. If the hinges on the doors are adjustable - this problem can be solved for a couple of minutes.
• The uniformity of gaps on all sides of the web is ensured by adjusting screws. And also, flush-mounted door hinges provide the swing angle up to 180 degrees, which can be fully appreciated when you have to bring large items into the house.

Note! In the presence of flush-mounted hinges, metal doors installed at the entrance to the apartment do not even need to be equipped with additional anti-dismantling elements. Since the hinges are not visible from the outside, it is impossible to cut them off when breaking. This fact is an undoubted advantage of this hardware, and most often, it determines the choice of the buyer.

• Since the hinges are designed for a particular load, they should be selected depending on the size and weight of the door leaf (see the parameters of interior doors - what you need to know about them). This fitting is installed not only on the entrance doors, but also on the interior doors, cutting it into the end of the casement and the box. In contrast to the overhead models, three hidden hinges are put on one canvas, which provides doors with additional reliability.

After hanging the canvas on the frame, make the adjustment of its spatial position. This is possible only if such function is provided in the installed hinges. The flap is aligned horizontally, vertically and clamping, and all that is needed is a hex key.
