Description

The utility model relates to the field of construction, namely, to protective devices for window, door or other architectural openings and can be used to securely close internal structures and eliminate the possibility of unauthorized entry into a building or room.

In the prior art, a device for closing a facade opening is known, which contains a sliding shutter installed between the supporting lower and retaining upper guides (see US Pat. No. 4,242,836, class EV6B 9/04, publ. 01/06/1981). The main disadvantages of this device are the lack of reliability of the protection of the opening, due to the fixation of the shutter in the closed position between the guides, and not inside the protected opening.

Also known is a device for closing an architectural opening containing a sliding shutter installed between the supporting lower and retaining upper guides provided with a fixing frame holding the shutter in the closed opening retaining the shutter in the closed position, with the shutter fixed to the supporting pivot levers hinged at one end on the shutter and the other end to movable carriages moving along the guide groove (see patent RU 178471 U1 cells. Е06В 9/04 publ. 04.04.2018). The disadvantage of this device is its excessive complexity.

The closest in technical essence to the claimed utility model is a device for closing an architectural aperture containing a protective shutter mounted on a carrier rail mounted on a wall above a closed architectural aperture, while the protective shutter is mounted on a longitudinal notch carrying a rail with support sleeves which are connected to the protective shutter with support bolts, while the supporting sleeves, made of a material with a low friction coefficient, are installed with the possibility Along the longitudinal notch of the carrier rail, the carrier rail at the end is attached to a fixing frame installed inside the closed architectural opening and has a transverse bend made in the plane of the carrier rail; details of the fixing frame, at the same time, the protective shutter contains protrusions installed with the possibility of their entry into the grooves made in the fixing AME, except that on the carrier rail pivot arm rotatably provided in a longitudinal section plane of the carrier rail can be installed (see. patent RU 183051 U1 class. Е06В 9/04 publ. 03.05.2018) The disadvantage of this device is the difficulty of closing the protective shutter in case there is no direct physical access of the person to the opening / closing process of the protective shutter, the presence on the carrier guide of the pivot arm reduces the reliability of the structure and makes it difficult to equip the device with an electromechanical system to ensure the movement of the protective shutter, and increased wear material from which the device supports are made.

A technical problem is the creation of a device devoid of the indicated drawback and providing the possibility of movement of a protective shutter or door leaf due to equipping the device with an electromechanical drive.

The technical result is to ensure maximum simplicity, reliability of the device and ensure the movement of the protective shutter, or door leaf with an electromechanical drive.

The technical result is achieved due to the fact that the closing device of the architectural aperture contains a protective shutter or door leaf mounted on a bearing rail mounted on the wall above or below the closed architectural aperture, while the protective shutter or door leaf is mounted on having two longitudinal notches bearing guide with support sleeves, which are connected to the protective shutter, or door leaf with support bolts, while supporting sleeves made of a material with a low coefficient Friction with the patient, installed with the possibility of movement along the longitudinal notches of the carrier rail, while each of the supporting sleeves has the ability to move along its notch, and along the entire length of the lateral faces of the longitudinal notches below the plane of the side of the bearing guide having longitudinal notches, vertical sides are made, the possibility of supporting them on the sides of the support sleeves, in addition to the inner surface of the bearing guide applied fluoropolymer coating.

Supporting sleeves can be made of metal, while they can be equipped with washers of a material with a low coefficient of friction, allowing the support sleeves to slide along the cutouts of the bearing guide.

On the fixing frame can be installed motor DC gearbox, made with the possibility of attaching to it the traction cable having the possibility of attaching its ends to the protective shutter.

On the fixing frame and the carrier rail, support rollers can be mounted, which can be supported by the traction cable.

The device can be equipped with a source of electrical power, made with the possibility of its inclusion in the electrical circuit together with the motor-reducer and providing the motor-reducer with electrical energy necessary for its operation.

The device can be equipped with a three-position switch, made with the possibility of its inclusion in the electrical circuit together with the motor - gearbox, changing the polarity of the voltage supplied to the motor - gearbox, as well as the ability to provide a change in the direction of rotation of the rotor motor - gearbox.

Limit switches can be installed on the fixing frame and the carrier rail, which can be switched into an electrical circuit together with a gear motor, with the possibility of pressure on them of a protective shutter and breaking of the electrical circuit.

Due to the fact that the device does not have pivotally movable parts, its simplicity and durability is achieved. The presence of vertical sides along the cuts of the carrier rail increases the contact area of the bearing sleeves with the carrier rail cuts, and reduces wear on the sides of the bushings. Application of the fluoropolymer coating, which has the possibility of contact with the bearing bushes, onto the inner surface reduces the friction of the bearing sleeves on the bearing guide and increases the durability of the device. The presence of an electromechanical drive ensures the operation of the device without direct physical access to it by a person.

The claimed technical solution is illustrated by drawings.

The closing device of the architectural opening contains a protective shutter 1 or door leaf mounted on the carrier rail 2 mounted on the wall above or below the closed architectural opening (Fig. 1, 2). At the same time, the protective shutter 1 or door leaf is mounted on the carrier rail 2 by means of support sleeves 4 and 5 fixedly connected to the protective shutter 1 or the door leaf by means of supporting bolts (Fig. 3). Supporting sleeves 4, 5, made of a material with a low coefficient of friction, are installed with the possibility of movement along the longitudinal notches 19 of the bearing guide 2, which can be at one end attached to the fixing frame 3 (Fig. 3) installed inside the closed architectural opening.

On the fixing frame 3 can be installed motor - gear DC 6 (Fig. 4, 5, 6) on the pulley 20 which can be fixed traction cable 7 having the ability to attach their ends to the protective shutter 1 or door leaf (Fig. 5, 6 , ten).

On the fixing frame 3 and the carrier rail 2, the support rollers 8, 9, 10, 11, 12 mounted with the possibility of supporting the traction cable 7 on them (Fig. 5, 6, 7, 9) can be fixed.

On the fixing frame 3 and the carrier rail 2, limit switches 13, 14 can be fixed, which are designed to pressure the protective shutter 1 or the door leaf against them (6, 7, 8).

On the support sleeves 4, 5, if they are made of metal, a washer 16 made of a material with a low friction coefficient can be installed (FIG. 10).

Along the entire length of the lateral edges of the longitudinal cuts of the carrier rail 19, vertical flanges 15 can be installed, which can be mounted on the lateral sides of the bushes 4, 5 (Fig. 7, 11).

Limit switches 13, 14, power supply 18 and 3-position switch 17 (Fig. 12) can be included in a single circuit together with a gear motor.

The dimensions, thickness and material of the protective shutter 1 or door leaf are determined by the size of the architectural opening being closed and the customer's requirements for strength and appearance.

The dimensions and thickness of the fixing frame 3 are determined by the dimensions of the protective shutter 1 or door leaf. The material of the fixing frame 3 is preferably a steel profile of rectangular cross-section, bent steel, wood, etc.

Bearing guide 2 can be made of galvanized steel profile, or steel sheet.

Support sleeves 4, 5 can be made of plastic with a low coefficient of friction and high mechanical strength or metal, in this case, washers made of a material with a low coefficient of friction 16 are mounted on the support sleeves.

To increase the durability of the device and reduce friction between the support sleeve and the carrier rail, a coating of fluoropolymer materials (Teflon) can be applied to its inner surface.

The power of the motor - gearbox is determined by the load required to set in motion the protective shutter 1 or door leaf.

The power source must provide the power necessary for the operation of the motor - gearbox.

The proposed device works as follows.

In the open position (Figs. 1, 2, 3), the protective shutter 1 or door leaf is positioned along the wall, being fixed through bolts and bearing bushings 4 and 5 on the bearing rail 2, which is fixed to the wall above or below the architectural opening to be closed. When the architectural opening is closed (Figs. 1, 2, 3), the protective shutter 1 or the door leaf moves in its direction due to sliding made of a material with a low friction coefficient, support sleeves along the bearing guide along its longitudinal cuts 19 (Fig. 3) . In addition, each support sleeve moves inside its longitudinal section. Support sleeves can also be made of metal, in this case, on the bearing sleeves, in the place of their contact with the carrier rail, washers are installed with a low friction coefficient 16 (Fig. 10).

Along the entire length of the side faces of each section, there are vertical edges 15 that reduce the wear of the side surface of the support sleeves 4, 5 as they move by increasing the contact area of the support sleeves and the carrier rail 2 (Fig. 7, 11).

The electromechanical drive for driving the protective shutter 1 or the door leaf along the carrier rail 2 consists of: a DC gear motor 6, a pull cable 7, support rollers, two limit switches 13, 14, a power source 18 and a three-position switch 17.

On the pulley 20 of the motor - gearbox 6, a traction cable 7 with its ends attached to the protective shutter 1 or door leaf is fixed to its middle (FIG. 5). To ensure the necessary tension of the cable on the carrier rail 2 and the fixing frame 3, the support rollers 8, 9, 10, 11, 12 are fixed (Fig. 5, 6, 7). To remove the cable and regulate its tension, the roller 8 can be made adjustable and spring-loaded (Fig. 5, 7).

After supplying voltage to the electrical network of the gear motor 6 and moving the three-position switch from the off position to the forward position, the motor pulley 20 of the gear 6 starts to rotate together with the traction cable 7 fixed on it. The force is transmitted to the protective shutter 1 or door leaf, and they begin to move along the carrier rail 2 in the direction of the protected architectural opening. When entering the protective shutter 1 or door leaf into the fixing frame 3, the shutter or door leaf rest against the normally closed limit switch 14 mounted on the frame 3 (Fig. 8). The electrical circuit in the limit switch opens, the rotation of the motor - gear 6 stops, and the protective shutter 1 or door leaf stops moving in the closed position. Three-position switch 17 is switched to the "off" position. After moving the three-position switch from the "off" position to the "on back" position, the polarity of the DC voltage changes, and the pulley 20 starts rotation in the reverse position, causing the protective shutter 1 or door leaf to move through the traction cable 7. Shutter 1 or door the canvas leaves the fixing frame and moves along the carrier rail 2 until it touches the limit switch 13 installed at the end of the carrier rail 2 (Fig. 6, 7). When this electric circuit is opened, the rotation of the pulley 20 of the motor - gear 6 is stopped, the protective shutter 1 or the door leaf is stopped in the "open" position. The three-position switch is set to the "off" position.

If necessary, a rheostat for controlling the speed of the shutter 1 or door leaf, a control unit for remote control of turning on the gear motor and changing the direction of its rotation and other electronic control devices can be included in the electrical circuit of the gear motor.
