Usually, all fences are equipped with gates. And if, to increase comfort, automation is installed on the gate, then the gates can be equipped with a door closer. This accessory ensures smooth and, most importantly, complete closing of the gate. Indeed, in a hurry, you may not notice that the sash is not completely closed.

Closer

What is a closer

The gate closer is a very useful device that ensures safety and increases the comfort of use. Its main functions:

  • ensures smooth closing of the gate;
  • makes sure that the sash is completely attached to the sugary bar;
  • can lock the door in the open position.

Also, the gate will not slam much when closing - and this is also a plus, since it increases the service life of the locking mechanism.

Operating principle

Despite the abundance of models on modern market, circuit diagram The operation of all devices is approximately the same:

  • when opening, it is necessary to apply a certain force - it is transmitted to the door closer;
  • because there is a spring in it, it is unclenched under the influence of this force;
  • also, the mechanism involves the use of a pneumatic or hydraulic piston;
  • thanks to this, the closing of the doors is smooth.

And besides, in many models, it is possible to set the desired clamping force and speed.

Pneumatic closer

Primary requirements

Since the gate closer is used on the street, a number of strict requirements are imposed on it:

  • frost resistance - it is very important that it works under negative temperatures, because if the device freezes, it will simply break during the first winter;
  • moisture resistance - again, the use of this accessory under open sky involves direct contact with rain and snow, so the design must have reliable protection from water penetration;
  • durability - according to normal, a good device should work for more than one year without problems.

Based on this, it is better not to purchase the cheapest models. And besides, it is necessary to take into account the wicket windage and weight - the power of the unit should assume the effect of wind on the plane of the structure.

Important! It is desirable that the mechanism be equipped with a special lock - it allows you to leave the gate in the open position. This is necessary in cases where you have to bring something into the yard, because if you just support the gate with a stone, this will create tension inside the closer, which obviously will not extend its service life.

Kinds

Today, three main types of closers are offered:

  • electric - provide silent and safe work. As an additional option, you can purchase a mechanism that will open and close the door with a button, however, for operation, you will need to supply electricity to the fence;
  • hydraulic - work is based on the use of a hydraulic piston, these are quite powerful and durable devices;
  • pneumatic - the most unpretentious closers, able to work at low temperatures and high loads. The work is based on the use of an air cylinder with compressed air.

Naturally, when choosing, it is worth proceeding from the budget, operating conditions, as well as the technical characteristics of the device.

Choice

To choose the right accessory, you need to consider the following parameters:

  • working conditions;
  • door weight - the power of the mechanism should be selected with a small margin;
  • you need to consider in which direction the gate opens;
  • the device must provide free opening to the maximum required position;
  • the ability to mount on the right or left door;
  • material for the manufacture of the unit body;
  • the possibility of adjusting the mechanism.

Also, when buying, you should pay attention to the complexity of the installation - the easier it is to do, the better.

Operating rules

As with any other thing, there are some rules when using a closer. If you are guided by them during the operation of this unit, then it can last a long time and without breakdowns.

Important! Most often, the working elements of the door closer cannot be repaired. Therefore, in the event of a breakdown, you have to buy a new device.

  • the gate should be closed with the help of a mechanism, you should not press it down with your hand and try to cover the sash faster - this can cause the mechanism to quickly fail;
  • do not leave the gate open for long time- since a strong voltage arises in the chamber and the spring, the mechanism wears out quickly;
  • periodically you need to make adjustments, the recommended frequency of maintenance is 2 times a year;
  • during adjustment, it is necessary to lubricate all rubbing parts.

Also, before installing the closer on the street gate, it is recommended to check the operation of the sash - it should open and close smoothly and effortlessly. If, for example, there are distortions of the canopies or the canvas itself, then such problems are best eliminated immediately. Otherwise, the closer will not be able to function normally and will quickly fail.

Adjustment scheme

Mounting the mechanism

First, you need to choose the right device. And here it is important to understand that there are closers that are designed for indoor use only. Therefore, in no case should they be used on the street, because. their elements are not designed for operation in conditions sub-zero temperatures and exposure to high humidity.

Next, you need to select the type of device. In fact, all proposed types provide the necessary functionality. However, there are certain limitations in their use. For example, for electrical appliances, must be connected to the mains. Those. such points must be taken into account initially.

Basic installation rules

Regardless of the type of accessory, there are several simple rules to be considered during installation:

  • most often you have to change the fasteners that come with the kit to more powerful ones;
  • it is better to mount the door closer with inside doors - it can be broken or stolen;
  • in order not to make a mistake with the markup, you should use the marking template that usually comes with the accessory;

Also, before installation, you should carefully study the instructions - this way you can avoid possible errors.

Installation

Installation instructions:

  • first, you need to make markings on the sash and on the support post, for this, a template is applied to the selected place and marks are made through it;
  • if the pillar is brick, then you will first need to fix a metal plate on it;
  • further, the device is attached to the door;
  • then, you need to fix the counterpart on the pole;
  • after that, the closing speed and pressure density are adjusted;
  • if the accessory is equipped with a lock button, then it should also be configured.

If it is necessary to install a closer for a street gate without a top crossbar, then models without a lever must be used. In this case, one part is attached to the pole, and the second to the sash. And such a mechanism works due to a spring and a piston. They ensure smooth operation of the outdoor door.

Thus, there is nothing complicated in the installation and it is not necessary to be a professional to carry it out yourself. The main thing is to initially choose the device itself correctly, and after installation, adjust according to the instructions.

In order to ensure the full porch of the gate to the frame, as well as its smooth closing, a door closer is provided. The closer on the gate allows you to close the doors without much effort. It often happens that in a hurry you did not close the gate closely. So that it does not remain open, this device will completely close it. It is very comfortable. Closers for gates today are presented in a wide variety.

What should he be

There are a number of requirements for this mechanism. And this is not surprising, because its operation is carried out not in favorable conditions. On the street, this mechanism is under constant influence. environment. Rain, damp, snow and more. So, it must match the following parameters:

  • High mechanical strength. This is an important requirement, because it is constantly under the influence of mechanical load.
  • Frost resistance. If the air temperature has dropped, it must continue to function.
  • Moisture resistance. Moisture has a negative effect on such mechanisms. Therefore, the street closer must cope with it.

Principle of operation

Although there are several types of them, the principle of operation is practically the same. To open the gate, you need to make a little effort. This force is transferred to the closer system and sets the piston in motion. After the piston, there is usually a spring that compresses. The energy accumulated in it creates pressure and the piston returns to its original position. As a result, the gate closes on its own. Due to the fact that there is air or oil inside, the system works smoothly and without sudden movements. In some door closer models, it is possible to adjust the gate closing speed.

What to look for when choosing

The choice of such a mechanism is a responsible matter. It is important to take into account a number of nuances. Otherwise, the purchased mechanism will not cope with the task successfully. Or in extreme cases, it will work for a while, and then quickly fail. So, the wicket system should be chosen based on the following parameters:

  • Power. This is one of the important parameters. Power must correspond to the weight of the entire gate. If the device is small and has a small power reserve, and the sash is large and heavy, then the device will fail very quickly. As well as vice versa.
  • The presence of a latch. Preferably, this latch should leave the gate in the "open" position. This is an important function, as there are situations when certain objects / things should be brought through the doorway. Thanks to this latch, the life of the door closer is extended.

Advice! If you have already bought this mechanism and it turned out that there is no latch in it, you can simply put a heavy object under the door. However, this should not be abused! The mechanism is designed to close. And his desire to complete this task will create a strong tension within the mechanism. This negatively affects the duration of its operation.

Varieties of closers

Closers to the gate street acquires the most different types. Now we suggest you familiarize yourself with the main mechanisms. They are of three types and differ in the principle of action:

  • Electrical.
  • Pneumatic.
  • Hydraulic.

Electric provide silent operation. Moreover, the door will open and close smoothly. The electric mechanism will ensure its safe use, especially if you have elderly relatives or small children.

It should be noted that opening/closing of the gate can be carried out in a non-contact way. For this, a special button is installed, which is enough to press. Such devices have different configurations, which allows you to choose it directly for your circumstances.

As for the hydraulic device, it is possible to adjust the force and speed of the wicket slam on it. Hydraulic mechanisms work with both external and internal types of loops. Their main advantage is that installation does not require special knowledge. You can install it yourself. One half of the device is mounted directly on the gate, and the second on the frame.

Another type of closer is pneumatic. Such a device should be purchased in conditions of enhanced and harsh use. The principle of operation of this mechanism is that when the gate is opened, air is compressed in front of the piston, and a vacuum is formed on its reverse side.

Pneumatic gate closers have the following specifications:

  • Ability to work at temperatures from -50°С to +50°С.
  • The opening angle reaches up to 160°.
  • The construction of the closer is made of stainless steel.
  • For sealing, polyurethane cuffs are used.
  • The pneumatic cylinder and the swivel assembly have a connecting hinge.
  • Possibility of installation on the left and right doors.
  • Can be installed both vertically and horizontally.

Operating requirements

Conclusion

So, we have seen that closers come in a variety of spring, pneumatic, hydraulic, and the like. If you have made his choice, then it is important to know how to use it correctly. After all, the duration of its operation will depend on this.

One of important requirements presented directly to the gate itself. Its hinges must be installed clearly without distortions. Otherwise, the efficiency of the closer is reduced. Moreover, the mechanism you choose must match the weight and size of the gate.

So, it is important to ensure the following requirements:

  • Do not forcefully press the gate so that it closes faster.
  • It is not recommended to place objects under the doors for a long time, holding the mechanism in the “open” position.
  • You should not just open / close the gate. Use it only for its intended purpose.

These are, perhaps, all the basic requirements that apply to the selection and operation of a gate closer. Consider the tips in this article and you will be able to choose the best mechanism that will suit your needs. If you have already made your choice and know about other nuances, then write about it in the comments to this article. It will help others to do right choice and not make a mistake.

Simple and reliable pneumatic device

Are you tired of the constant loud slamming of the gate? The slightest breeze makes your gate close with a roar? Why endure and listen, there is an opportunity to eliminate this trouble, all the more serious financial investments, on the mechanism holding the sash, will not be needed.

More enterprising and inventive owners find a way out in a simple way- an ordinary strong spring can keep the door in the opening from the wind. One end of the spring is attached to the leaf of the gate, and the other end is located on its support post. But such a mechanism is not always convenient because little child or it is difficult for an elderly person to open a sash fixed with a powerful spring. Yes and appearance such a device is not very attractive.

In building supermarkets a huge selection of pneumatic, electric or hydraulic closers that can be installed on street doors. These devices provide smooth closing of the gate, which reduces the likelihood of breakage, softens the blow, and they look more presentable.

Types and design features

Schematic representation of a pneumatic device

This additional accessory improves the functionality of swing systems, both wickets and gates. Manufacturers have taken care of the quality of these devices, which allows their use in various climatic conditions. High-quality closers are frost-resistant, wear-resistant and durable. They do not corrode and are able to withstand severe loads.

When choosing, you should pay attention to the degree of load, frequency of use and, accordingly, to the characteristics of the product. By their own design features mechanisms are divided into three main types:

  1. Electric - silent, reliable mechanisms that provide multiple movements of the gate. This mechanism increases the level of safety for children and the elderly. It is a versatile, rugged and compact device that is easy to install yourself.
  2. Hydraulic - adjustable mechanisms in which the force is regulated, as well as the speed of closing the sash. Installation of such a mechanism is quite easy, as it comes with instructions with a detailed and consistent description. Mechanisms are designed to work in various weather conditions.
  3. If operation of a gate in the strengthened and severe conditions is necessary, then it is better for you not to find the pneumatic closer. Its simplified design allows gentle closing by compressing air with a piston, on the other side of which a vacuum is created. These are just those mechanisms that do not require additional care. In addition, they can work at low temperatures, and their possible opening angle is up to 160º.

Prevention and inspection of knots

Such closers are made of high quality steel, their cuffs are made of polyurethane, and the swivel assembly and cylinder are equipped with a swivel joint. Such mechanisms are mounted on any side of the opening and in any direction. This device is the most durable and unpretentious in maintenance, moreover, it does not require regular adjustments.

You can make a door closer yourself, you will learn about one of these from the video.

Rules for mounting a useful accessory

To provide long term operation requires compliance with the rules for the installation and operation of the mechanism. The conditions are not so unrealistic as to be ignored. First, about the installation.

You should carefully consider the choice of fasteners for the mechanism. This takes into account the force of opening the gate, and the greater the effort, the more reliable the fasteners should be. Even if the kit is equipped, in your opinion, with unreliable fasteners, it is better to replace them.

Closers for internal use on street gates cannot be used. And after installing the device, you should adjust its actions with a screwdriver.

Some models of closers have additional functions, for example, fixing an open gate. To ensure that the sash is held, tighten the nut on the lever.

The sequence of the entire installation process of any type of door closer is practically no different from each other. You can learn more about this procedure from the video.

Operational Requirements

Well, the most important thing! If your gate or its hinges are installed poorly, that is, there are distortions or the instability of the hinges is noticed, then the life of the door closer is significantly reduced.

It is important to comply with all operational requirements:

  • it is not recommended to make efforts to close the sash more quickly;
  • any objects inserted into the opening, in order to keep the sash open, lead to damage to the mechanism;
  • it does not follow once again without the need to close and open the doorway. Often children arrange games with the participation of protective structures.

It is extremely rare that a device can be repaired, more often it has to be replaced. Like any other mechanism, the door closer requires a careful attitude, and in gratitude, it serves its owners for a long time and without fail.

NOTEDO GS35-HO

You often ask us: "Which closer can be installed on a street gate?"

Unlike ordinary doors, street gate does not require installation door frame, it is attached directly to the fence post and there is nothing on top of the gate. Therefore, a classic door closer or a door closer with a sliding channel cannot be installed, because the closer needs a place to be installed exactly above the gate, so that this place is in the same plane with the gate. Yes Yes! - you need a place just above the gate, neither from the side, nor from below, but above the gate.

NOTEDO found a solution to the issue

Answer found! NOTEDO has come out of the situation and started deliveries to Russian market pneumatic door closer. The principle of operation of this closer is based on air compression, as in gas shock absorbers. When the door is opened, the piston compresses the air in the cylinder compressed air presses on the cylinder, returning it to its original position. The closer has control valve to adjust the speed of closing the door, as well as a device for fixing the door in the open position (). The closer is mounted on one side on a pole or wall with a bracket, on the other side with a "shoe" is attached to the door. According to this principle, the closer can be mounted not only on street gates, but also on any doors on which it is not possible to install lever closer. The only condition is that the door should not exceed the maximum parameters in terms of weight and width.
