Door bilateral loops for pendular doors

In everyday life, there are often situations where the most convenient would be a door swinging open in any direction. But conventional canopies do not allow it. But there are special door bilateral hinges, designed specifically for such structures. They are often called pendulum or bar.

On the features of such loops, the scope of their application, device and installation will be discussed in this article.

Scope of application

The easiest way to illustrate the work of pendulum doors on the example of cowboy salons. They say that cowboys used to visit the bar directly on the horse, and she, as you know, cannot open the door to herself. Therefore, they invented designs that move freely around the axis in any direction.

Now the scope of application of the pendulum loops have become mainly places with high traffic of the people - commercial premises, railway stations, subways. They are also convenient in cases where it is difficult for a person to open the door to himself. For example, if his hands are occupied, or it is a wheelchair user.

Therefore, the door hinges of double-sided opening are often used in medical institutions, catering establishments and warehouses, as well as in apartments in which elderly people or people with disabilities live.

But such constructions do not always perform a utilitarian function only. They are very organically fit into some interior styles. For example, the last picture shows a decorative wooden gate, stylized as an entrance to a cowboy salon.

Features and types of double-sided loops

Externally, two-way door hinges are like all the familiar card.

Design features

Unlike conventional card loops, they have not two plates on the same axis of rotation, but three on two. Moreover, the middle is between the axles, and has no mounting holes.

The most common canopies, in which springs are installed inside the studs. They return the flaps to the closed position no matter in which direction, and for what amplitude they were open.

Kinds

There are such sheds in several ways:

• In the direction of opening the sashthey can be right, left or universal;

Council To understand which loops you need, stand facing the door and imagine that you are opening it to yourself. If you do it with your right hand, the canopies should be right-handed, if your left - left-handed.

• By way of installation - screwed and welded. The latter do not have mounting holes on the maps, as they are welded to the metal box and the door frame. Used primarily for street and garage doors and gates. They are almost never found on the market, but the craftsmen make them from two ordinary welded canopies, welding metal plates to them.

• By design. Here we consider only patch hinges for ordinary wooden doors that are attached to the end of the canvas and the door frame. But if the door is made of glass or metal, fasteners for its two-sided opening has a completely different design. As a rule, it is installed in the upper and lower end of the canvas and comes with it.

For reference. Similar hinges are produced for wooden doors. They are called Italian. But they almost do not use demand - rather high price confuses.

Selection options

To choose reliable and suitable for you double-sided door hinges, you need to pay attention not only to their appearance and color. This, of course, is also important for aesthetic perception. But more importantly, the door worked normally and served for a long time.

Therefore, we consistently evaluate the following parameters:

• Opening direction. This has already been said above.
• Dimensions. First of all, the width of the cards, which should not be greater than the thickness of the door leaf.

• Permissible load. It is unlikely that the instruction manual is attached to each canopy, but the seller should have information on the maximum load on it.

Council Keep in mind that the load indicates one loop. Knowing the mass of the door leaf, you can calculate the required number of awnings.

• Appearance. This is the shape that may differ from the standard rectangular. And the color that is matched to the door or other details of the interior. The choice is quite large: gold, chrome, brass, bronze in matte and polished design. There are canopies covered with powder paint of different colors.

Some products are equipped with additional features. For example, bearings for smooth and silent movement and elements of speed control spontaneous closing of the door.

Installation

Installation of such loops is slightly different from the installation of conventional card. To better understand the description below, look first at the completeness of the products and their scheme.

So, door bilateral spring hinges can be adjusted by changing the force of compression of the springs. Before installation, they must be loosened, and after it - preloaded to ensure the independent return of the canvas to its original position.

• 1 - spring;
• 2 - sleeve with holes for the stopper;
• 3 - stopper;
• 4 - locking screw;
• 5 - end nut.

And the mandrel is a metal pin with which the adjustment is made.

Now you can see how to install the door on the double-sided hinges with your own hands:

Picture	Description
	To release the spring, you need to remove the stopper from the hole in the sleeve. To do this, insert the mandrel into the nearest free hole and turn the sleeve clockwise. The stopper is released and can be easily removed.
	Then everything is as usual: mark the position of the hinges on the end of the canvas and the door frame.
	By marking cut grooves in the body of the box and door leaf.
	Insert the loop card into the groove of the box and fasten with screws.
	We repeat the same with the second card, screwing it to the door.
	After installation we cock the springs in both pins. Again, with the help of the mandrel, turn the sleeve clockwise, inserting it into the hole located closer to the map. And in the vacant hole insert the stopper. Then we leave, close the door and repeat the procedure on the second pin. Check the smoothness of the course and, if necessary, tighten or loosen the spring.

Council Adjustment should be carried out carefully, without putting much effort. Otherwise, you can break the spring.

Often, the springs themselves weaken during long operation. In such cases, they are tightened again. The main thing - do not lose the mandrel.

Conclusion

Double-sided door hinges are indispensable if you need to ensure the smooth passage of a large number of people or the free movement of people with busy hands. They are very convenient for hanging gates and gates in private homes.
