Roller shutters for caring owners and business people. How to open electric roller shutters mechanically? How electric roller shutters work

The advantages of using roller shutters are obvious and undeniable. roller shutters perfectly cope with the functions of protecting your building from unauthorized entry, allow you to create a respectable and aesthetic appearance of any object.
The optimal design of the roller shutter system provides the protective functions of the interior equipment of the rooms from the scorching sun, from prying prying eyes, and also has soundproofing properties.

Roller shutters include the following devices:

• A protective box with a shaft located inside, on which the roller shutter curtain is wound.
• Roller shutter canvas, consisting of lamellas, securely fastened together.
• Side tires that perform guiding functions when the web moves.
• The control mechanism that drives the roller shutters.
• Locking mechanism for manual operation or control panel for designs with electric drives.

The mechanism of roller shutter operation is based on simple actions of simple elements. The roller shutter is driven by the control mechanism and moves along the guide rails in the vertical direction, opening or closing the window opening. When the roller shutters are raised, the lamella structure is wound on a shaft located in a box, which is located mainly in the upper part of the structure. At the request of the customer, the location of the box in the lower part of the roller shutter structure is possible.

Why are roller shutters better than window grilles?

Compared to grids, roller shutter systems in non-standard cases (earthquake, fire) are easily set in motion, providing the ability to evacuate people from the building, even in systems with an electric drive. Given the high humidity typical for St. Petersburg, roller shutters do not rust compared to metal gratings and do not need periodic painting.
Structures made of extruded profiles have increased burglary resistance, do not need special care and are able to function properly for many years. Roller blinds are cleaned of dust and dirt with a cloth, using ordinary detergents. After an attempted break-in, mechanical damage to roller shutters can be easily eliminated by replacing the damaged lamella.

Varieties of roller shutter profiles

The functional characteristics of roller shutter systems are determined by the type of profile used. Roller profiles are produced in two ways: by roller rolling and by punching (extrusion).
The roller rolling method makes it possible to obtain a hollow aluminum or steel strip, which is then filled with a special foam that provides heat and noise insulation properties. Such systems are quite strong and light.
Extruded profiles have higher strength indicators due to the presence of a transverse stiffener and wall thickness (from 1 to 1.5 mm). They are used in places with the necessary provision of increased security of the facility.

Roller shutter control systems

1. Mechanical (manual) control:

• A manual bolt in combination with sliding stops provide fixation of the roller shutter curtain according to the latch principle. Management is carried out from within the building.
• Use of a lock bar. The last bar of the canvas is equipped with a lock with keys, due to which the system is locked. Management is carried out both from the inside and from the outside of the building.

2. Electric drive control:

Inside the protective box there is an electric drive that ensures the raising or lowering of the roller shutters with the obligatory blocking of the system in the lowered state. Electrically driven systems are equipped with emergency manual controls that are activated in the event of a power outage.

Types of management

torsion spring from 6 to 72 kg	Cassette cord up to 12 kg	Vorotok to 32 kg.	Reducer- winch up to 81 kg	Manual control for roller shutters: Manual bolt - a pair of sliding stops, acting on the principle of a latch, control from the inside. The lock bolt is a lock with keys in the last bar of the leaf, locking is possible both from the inside and from the outside.

Roller shutters are a type of blinds that are designed to be installed from the outside of window or door openings. They are a metal sheet consisting of individual high-strength plates.

They perform the function of protecting a room or building from burglary, provide sound insulation, and prevent the effects of precipitation on doors or windows. They can be used on the principle of blinds - to prevent sunlight or daylight from entering the room.

The design of roller shutters and the principle of operation

Roller shutters consist of 4 main elements:

1. a canvas of lamellas hinged to each other - made of steel or aluminum;
2. box - it contains a shaft on which a metal sheet is wound;
3. guides - auxiliary elements to prevent the structure from leaving the lamellas outside the window / door;
4. drive mechanism - with its help, lifting and lowering (opening and closing) is carried out.

In addition, roller shutters from the manufacturer - RDO are equipped with various control elements, the variety of which depends mainly on the type of installed drive (manual or electromechanical).

The principle of operation of roller shutters is as follows. The web of lamellas is set in motion using a manual method or remote control. Sliding along the side guides when lifting, it is wound on the shaft in the box, or lowered under the influence of its own weight. In the closed position, the roller shutters are fixed by means of a locking mechanism or due to the design of the shaft and box.

Classification

According to the method of fastening roller shutters are:

• built-in - guides are built into the window opening, which makes them more reliable;
• overhead - installed on the outer surface of the wall, which significantly reduces the degree of protection (guides can be torn off or bent).

Depending on the drive, they can be:

• electromechanical - with remote or radio control;
• manual - equipped with roller shutters with a leaf weight of not more than 30 kg, which can be lifted without much effort, if necessary, they can be equipped with a handle or cord for lifting to a great height.

For different manufacturers, the design of roller shutters and their principle of operation are practically the same, and the price of products of the same size may vary depending on the quality of the installed controls.

Until recently, only lattice structures could protect against intrusion on private property. Far from presentable, but endowed with good reliability characteristics, they rarely fit into. No matter how hard the skilled iron experts tried, creating their “masterpieces”, these designs evoked nothing but an association with a prison cell. Over time, the level of security provided has also been greatly shaken. Modern construction tools - hacksaws and grinders, are able to quickly cope with the grate. The demand for another method of protection has matured on the market, and, of course, it has appeared.

A modern alternative solution to the problem of building security has become roller shutters (roller shutters), combining reliability and aesthetics. The installation of roller shutters has become a real gift for all people who want to protect their homes without violating the design of the building.

Objectively speaking, shutters are the only way to secure a building with minimal impact on the overall architecture of the building. Thanks to this, the eternal issue between entrepreneurs who want to secure their stores and other strategically important premises and the city hall, which seeks an aesthetic appearance, has been resolved. The owners of residential buildings also did not stand aside and appreciated the roller shutters.

Every day more and more models of roller shutters appear on the market, made using different technologies and using different materials. Before making a choice, it is advisable to familiarize yourself (at least in general terms) with all the possible options, the price of which is strikingly different.

Modern roller shutters are able to provide varying degrees of security, which allows everyone to find the best option for themselves.

Types of roller shutters, design and features

Roller blinds or protective blinds (not to be confused with ordinary ones) - multifunctional devices. In addition to the protective function, they improve light and. Thanks to them, a full-fledged protection of a private house, apartment, shop or any other building is carried out.

Roller shutters can be installed on any potentially dangerous areas through which you can get inside the premises. Basically it is door and window openings.

Why are roller shutters more effective than gratings? A simple example: a stone thrown through a window can easily overcome the lattice protection, but it will not work to break through the roller shutters.

Properly selected and well-installed structures have exceptional anti-burglary characteristics if they were established for these purposes. After all, roller shutters can only be installed to increase the level of sound insulation or for decorative purposes. Therefore, before purchasing roller shutters, decide what you are doing it for.

Roller shutter systems have good anti-corrosion characteristics, are not afraid of temperature changes and do not need to be painted.

Regardless of the design, all roller shutters structurally consist of three main elements: a canvas, a box and guides.

Roller shutters are made from different materials. Most often it is aluminum, plastic or steel. Aluminum lamellas (lattices) are considered the golden mean. They have good strength, lightness and are not subject to corrosion.

The operating principle of roller shutters is simple: guides are located along the edges of the structure, the canvas moves along them, winding up on a shaft, which is protected by a box.

Winding on the shaft is realized in two ways: manual and electric.

Roller blinds for windows - a beautiful security solution

For rolling window systems, it is better to use aluminum-based canvas. This material is not subject to the negative effects of sunlight, has sufficient strength, lightness and anti-corrosion properties. In whatever conditions aluminum-based roller shutters are used, they will cope with the protective function without any problems. A variety of polymer coatings allow you to make roller shutters of different colors. It is easy to wash such structures, and dust practically does not settle on them.

Window roller shutters can be equipped with various drives. The relative lightness of the design allows the use of cheap manual designs. For connoisseurs of comfort or owners of large panoramic houses, high-tech electronic multi-drives are suitable, in which several roller shutters can be controlled at once by one remote control.

The lamellas that make up the canvas are attached to each other on hinges. Depending on the purpose, the lamellas can be with or without filler.

Installed roller shutters on the windows are also economical. By reducing heat transfer, resources used for space heating are saved. In the summer, the reflective ability of the structure plays into the hands of the owners. Sunlight from the roller shutters is reflected, which contributes to a slight cooling in the room.

With the active use of roller shutters, there is one problem: the failure of the driving mechanism.

To increase the life of the cable, you need to follow these simple rules:

1. Roller shutters with a manual mechanism should be raised smoothly and slowly.
2. Make sure all locks and safety devices are unlocked before lifting.

Otherwise, roller shutters are very reliable, durable and high-quality equipment.

Roller shutters for the garage: convenience and reliability

Along with window roller shutters, garage roller shutters have also become very popular. After all, they have a whole range of competitive advantages when compared with conventional swing gates.

1. Space saving. Remember how many extra meters you need to allocate under (access area) in order to seamlessly open the gate. Roller shutters do not need this space at all: the canvas simply rises up.
2. Comfort. Equipped with an automatic (electronic) way of operating the drive mechanism, roller shutters provide a person with a very significant advantage - you do not need to get out of the car to open and close. All the charm of this function can be felt on a cold winter morning or windy evening.
3. Reliability. In terms of their protective characteristics, garage roller shutters are not only not inferior, but for a number of reasons they are superior to standard gates. The main advantage is the inability to break the lock by picking up the key to it.

Garage roller shutters can be selected from aluminum or steel. The aluminum construction is less heavy and has the good features we talked about before. However, it is still preferable to install steel roller shutters. After all, they have the best strength and provide maximum protection for the expensive equipment that will be there.

Protective roller blinds with a sheet of metal slats - roller shutters - have long become a lifesaver for businessmen of large and small hands. Installed in the openings of windows and doors, they protect kiosks, shops, first floors of business centers, shopping and entertainment complexes from breaking and unwanted entry. To facilitate and speed up the lifting or lowering of the canvas on several openings, to do it synchronously, without leaving the room, even when you are not on site, an electric drive for roller shutters will help.

Benefits of automatic roller shutters

The manual drive allows you to raise or lower the roller shutter curtain thanks to an inertial mechanism with a spring, when it is enough to pull the roller shutter in the right direction for further movement, or to the cardan mechanism - in this case, you need to turn the handle.
Manual control of roller shutters weighing more than 35 kg becomes physical work. It is difficult to imagine the loss of time and effort of a person whose duties include maintenance of protective roller shutters on the territory of some shopping and entertainment center. Electric shutters on the windows in this situation is the only right choice. The owner of the only roller shutter, spoiled by comfort, will not refuse the convenience of the electric drive.

Remember! If the network is not de-energized, it is forbidden to use the emergency manual lifting of the roller shutters. This is a common cause of drive mechanism failure.

What else attracts the consumer with automatic roller shutters:

• The user does not need to know the principle of operation of the roller shutter lifting mechanism and the procedure for its maintenance. Even a child will be able to press the corresponding button of the switch or control panel.
• Roller shutters do not require any physical effort. This is an important advantage of the electric drive, given that modern roller shutters for garages and other large openings can weigh more than 500 kg.
• Possibility to combine the electric drives of all roller shutters with a common network. It is very convenient to manage the entire protective complex from one place.
• The use of a radio remote control allows remote control, and the use of a smartphone - in the absence of owners on site.
• The control unit for all roller shutters of a certain complex can be combined with a security console or video surveillance room equipment.
• The required lifting and lowering height of the web can be set by adjusting the limit switches. In extreme positions, the drive will be switched off.
• Possibility of installing an automatic lock at the top of the structure.
• Motorized roller shutters can be integrated into the smart home system.

The disadvantages of the electric drive are the attachment of the mechanism and equipment to the power supply, the limitation of the minimum width of the opening to be closed by the dimensions of the drive, as well as the high cost.

Selection, installation and connection of the electric drive

Important! Being engaged in self-installation of the electric drive, the consumer loses the right to guarantee the operation of the device, which he receives when the work is performed by specialists of the profile organization.

When choosing a specific type of electric drive, one should take into account: profile web weight, shaft diameter, supply voltage, drive dimensions, rotation speed, power consumption, torque, emergency opening system, the ability to integrate a radio control module. To facilitate the task, special selection tables offered by manufacturers will help. It will not be superfluous to consult specialists of a specialized organization that not only installs electric roller shutters, but also sells drive mechanisms with accessories.

In order to smooth out the acuteness of the financial issue, to amuse the self-esteem with a positive end result, each economic consumer can study the connection diagram and cope with the installation of the electric drive on their own.

The procedure for installing an electric motor on roller shutters is as follows:

• The side cover is removed from the box that protects the shaft with the rolled curtain.
• Crossbars are disconnected from the shaft.
• The released shaft is removed.
• An adapter is put on the drive, then a special holder of the end position.
• For future fixation of the side cover, a mounting plate is screwed onto the electric motor. Then holes are drilled corresponding to the attachment points.
• The electric motor is screwed to the side cover of the box through the mounting plate.
• The capsule with inserted bearing is installed on the other side of the engine.
• The resulting prefabricated structure is installed in an octagonal shaft.
• The bearing capsule, located at the other end of the shaft, extends outward to the maximum end position and is fixed in the cover. Rivets are used for fixing. Corresponding holes are pre-drilled on the shaft and in the bearing capsule for them.

The installation of the actuator is completed. The next step is connecting to the mains. The four-wire cables through which the drive is connected to the mains supply are color-coded:

• yellow-green wire - grounding;
• blue - neutral;
• black and brown wires - phases of the direction of rotation in different directions.

The switch device must provide for phase blocking. This will prevent two opposing rotations from engaging at the same time.

Using the adjusting screws "+", "-" on the head of the electric motor, the extreme limits of the operation of the limit switches are set.

Important! Power surges can knock down the settings of the limit switches. Combine periodic debugging of switches with inspection of roller shutters.

Popular manufacturers supplying high-quality electric roller shutter drive mechanisms to the domestic market:

• Somfy (France);
• Novo, An-motors (China);
• SELVE, Becker, Elero (Germany);
• Mottura, Nice, Came (Italy).

The roller shutter leaf is driven by an electric drive (8) using a remote control (15) or a switch (16). Switches are of three types: keyboard, lock and remote.

To raise or lower the roller shutter, you need to press the corresponding button on the remote control (15) or press (turn) the switch key (16) in the direction of "raising" or "lowering", respectively, and hold until the curtain stops completely. To stop the blade in an intermediate position, you just need to release the button.

Locked switches require the key to be inserted and turned to raise/lower the roller shutter.

There are latching switches. In this case, it is not necessary to hold the key (or key) of the switch until the roller shutter curtain stops completely. The stop will occur automatically, but after that it is necessary to set the key (key) to the neutral position. To stop the roller shutter in an intermediate position, you need to return the key (key) to the neutral position. Momentary switches are preferable in terms of electrical safety.

Electric actuators are not designed for permanent continuous opening / closing, as they can overheat. They are not recommended to be installed on objects where a high frequency of raising/lowering roller shutters is required.

At your request, the electric drive can be supplied with an emergency manual lifting mechanism - a crank drive. It allows you to raise (lower) the roller shutter in emergency mode in the absence of voltage in the network.

The roller shutter curtain is driven by a gearbox (9) using a crank (19) connected to the gearbox through a cardan (17).

Raising/lowering the curtain is carried out by turning the knob until the stoppers of the roller shutter box touch (when lowering: until the curtain lamellas are completely closed). Further rotation of the handle is prohibited: it requires considerable effort and leads to damage to the structure.

At your request, it is possible to install side valves or a bolt lock in the end profile of the product. At the same time, before opening the roller shutter, it is necessary to unlock the roller shutter curtain: by turning the key, open the bolt lock or bring the side latches mounted in the end profile (16) to the curtain center. Accordingly, it is possible to block the roller shutter curtain after lowering.

When lifting the roller shutter leaf, it is necessary to pull down the tape (or cord) as many times as necessary until the roller shutter leaf is in the desired position.

When lowering the roller shutter leaf, it is necessary to take the tape (cord) near the body of the tape layer (cord stacker), pull it towards you and then smoothly release the tape (cord), without releasing it (it) from your hands. Repeat this operation until the lamellas are completely closed in the canvas.

Raising the roller shutter blade is done by turning the handle (21) clockwise, lowering the blade is done by turning the drive handle counterclockwise.

In the end profile of the product, it is possible to install side valves or a crossbar lock. See "Roll-up Roller Shutter Installation".

Be careful: the gearbox is easy to break if you turn the handle when the blade has already stopped in the up or down position.

Roller blind is driven by an inertial spring. To lift the curtain, hold the handles on the end profile (14) and smoothly raise the roller shutter curtain until it stops completely in the upper position. To lower the roller shutter curtain, it is necessary to pull the curtain by the handles on the end profile until it contacts the supporting surface (window sill, threshold of the opening, etc.).

Roller shutters with a spring-inertial mechanism for raising/lowering are equipped with a crossbar lock that cuts into the lower end profile or side latches. When opening / closing the lock, it is necessary to hold the handle on the end profile with your free hand to prevent a sharp rise and folding of the roller shutter leaf.
