Description

The group of inventions relates to the field of construction and relates to design options for ceiling sectional overhead gates, as well as the guide system used in them. The claimed gate designs can be used to block openings with a low and very low ceiling in residential buildings in order to prevent unauthorized access to the room, providing thermal insulation, light and noise insulation of the room.

Interest in the design of sectional lifting gates for blocking openings with a low (less than 150 mm) and very low (less than 100 mm) lintel arises from the desire of people to compact auxiliary rooms (garages) and the desire to make the most of the available volume of the auxiliary room, and also in connection with the widespread use of standard modular reinforced concrete structures for building garages in Europe.

Known (KI патент 220, Ε05Ό 15/24, published September 20, 2000) articulated ceiling gates for doorways with a particularly low bridge height between the upper edge of the doorway to be closed and the ceiling area bordering it, containing a door leaf consisting of several sequentially articulated in the direction of movement of the panels, which are moved by means of rollers installed on their sides in a guide system, including: first side guides containing vertical and horizontal sections arcuate connection therebetween; second guides having a horizontal part and an end part adjacent to its end, which, with its first portion, is slightly inclined to the horizontal, and with its second portion slightly bent more than 90 ° to the horizontal, is bent towards the floor.

The closest in the set of essential features for the first version of the declared sectional lifting gates for a low lintel with a balancing device on helical springs and for a single guide system used in both declared variants of the gates is the well-known (KI, C2, Ε05Ό 15/16, Ε05Ό 13/00, published on 09/20/2000) a technical solution - a gate with a door leaf moving overhead in the guides between the closed and open positions and with one end attached to the door leaf and the other It is secured by a fixed balancing device containing at least one coil spring assembly, consisting of at least two coaxially arranged coil springs, the inner of which has an outer spiral diameter smaller than the spiral inner diameter of the corresponding outer spring, while the coil springs made in the direction of elastic energy storage deformation in the form of tension springs and the ends of both coaxial springs forming one spring block are made by at least one the common end, ending in a spiral shape, and pulled onto a common fastener, which has a first, narrow spring-facing fastening portion for attaching the internal spring, and a wider adjoining side from the springs opposite to the springs, for attaching the external spring, sections at their edges are made with hook-shaped protrusions interacting with the spring coil pulled in and reliably preventing their removal. In this case, the guiding gate system includes two first guides, each consisting of a horizontal, arched and vertical sections, and two second guides, each consisting of a horizontal section, descending (if you look in the direction of the door leaf) section and an end section bent at an angle.

In the known guiding systems (patents No. 2178499, 2203379) of gate constructions, each vertical guide (the vertical straight-line portion of the first (side) guides) and connected to it by means of plates and brackets by welding, riveting or using fasteners, an angular stand designed to fix the system guides to the wall, form an assembly unit (vertical section of the guide system), and horizontal sections of the guides are made of separate profiles interconnected by plates or brackets.

The disadvantages of the prefabricated structure, consisting of a profile of an angular stand and a straight vertical guide, connected at an angle to each other so that the vertical guide forms an angle from 1 to 3 ° with the wall, include an increase in assembly dimensions with an increase in the length of the vertical guide (with length vertical rail, for example, up to 3 m the assembly size will increase to 150 mm) and, as a result, the dimensions of the product, in which the rail system with such a prefabricated design is used. In addition, the use of inclined vertical guides requires the use of side supports for the rollers protruding from the door leaf into the room, which prevents the installation of a casing for protecting the movement zone of the rollers, i.e. reduces the safety of gate operation.

The use of vertical guides in the guiding system of prefabricated structures with corner posts, as well as horizontal sections of the first and second guides made of separate profiles, increases the complexity of manufacturing elements of the guiding system and the metal consumption of the whole product. In addition, a common drawback of these prefabricated structures (a vertical guide with an angular stand and horizontal sections of the first and second guides with each other) is the presence inside the guide connecting elements in the form of large, riveted or welded joints, the protruding elements of which not only worsen the appearance of the product, but also create obstacles to the movement of the rollers. It should also be noted that during the separate assembly of the nodes of the left vertical guide and the right vertical guide mirror with corner posts, there is a possibility of a difference in the angles of inclination of these guides and, as a result, possible distortion of the end sides of the door leaf relative to each other, as well as distortions and deformation of the door leaf when moving along the guides.

The balancing device used in the known gate design with the cable rods provided for it is installed in the corresponding horizontal section of the rails in such a way that the coil spring unit is parallel to this section and is fixed on one side on the opposite end of the horizontal rails and facing the gate the side of the canvas has a guide roller, on the grooves of which two cables are passed, which run in parallel and are fixed by their own ends stationary at the end of the horizontal rails closest to the portal opening, and others at the common mounting point in the area of the lower edge of the lowermost closed door of the panel door. The disadvantages of the horizontal arrangement of the known mechanism for balancing the gate with tension springs include the insufficient reliability of the assembly structure of horizontal guide rollers and a horizontal spring guide (spring block guide) to the ceiling, the cost of this site.

In some designs of well-known gates, a horizontally located spring block-spring mechanism for balancing the gates takes up additional space above the horizontal rails, which implies an increased lintel, and, in addition, causes difficulties in mounting and adjusting the tension of the spring mechanism due to the inconvenience of access from above between the ceiling and the edge of the guide profile for springs;

sagging springs, resulting in the need to install intermediate spacers, which in turn impede the smooth operation of tensile springs; sagging of the internal spring, leading to the possibility of jamming of its coils between the coils of the external spring.

From publicly available sources it is known (No.№.thea1-da1egi / sa1a1o§ / 27/95) the use of the design of sectional lifting gates for low lintels, in which a spring block-rope mechanism for balancing the gates of vertical arrangement is used: the blocks of coil springs of the mechanism are placed vertically along the guides left and right of the opening inside the space between the end of the door leaf and the inner surface of the corner post. However, such an arrangement of the gate balancing mechanism does not allow the balancing mechanism to be delivered to the installation object in a state assembled with a vertical guide and an angle strut and with pre-tensioned springs, as the space for placement of balancing mechanisms coincides with the space necessary for fixing the corner posts to the wall. In addition, it should be noted that the design of the fastening sections of the ends of the springs of the coil spring unit of the known balancing device involves screwing the end (or its latch) into the spring, which increases the complexity of the assembly of the balancing mechanism itself.

As a prototype for the second version of the claimed design of sectional overhead gates for a low lintel, the well-known (1Wr: / L \ lu \ u.go1151aupu.gi / Y1ges1yup7.r11r) are adopted. containing a door leaf that is movable in the guide system, sectional ceiling doors in which the door leaf is balanced by a torsion (spring-inertial) mechanism, which is installed in bearings mounted on the corner posts of the end support brackets with at least one torsion spring, one end of which is fixed to the shaft and rotates with the shaft, and the other is fixed to the wall using the internal support bracket, and with a pair of rigidly fixed to it the ends of the drums, winding themselves upon rotation of the shaft cable, mounted on the lower corner bracket of the door leaf.

A known (KI, 2226597, C2, IPC Ε05Ό 13/00, published April 10, 2004) system that blocks the door leaf when the torsion spring is damaged is a device for monitoring a torsion spring that works with prestressing, which is provided as a balancing spring for the movable above the head of the door leaf to prevent slamming or falling of the door leaf containing, together with the torsion shaft loaded by an unbroken spring, a blocking element which, to block this rotation movement and as a result of this movement of the door leaf, it is capable of being gripped and locked by means of a catching link containing gearing, as well as a sensitive and starting device for sensing the spring tension and causing the movement of the catching link from the working position to the catching position, as a reaction to the spring break registered by the sensing element.

Among the disadvantages of the known device for controlling the spring, it should be noted the use of a special (non-standard) bracket for attaching to the wall of the device and a special cable drum with an internal gear ring on the outer shell, which, when the spring breaks, perceives the shock load of the catching unit of the device, which can lead to the destruction of the cable drum and thus spoiling the winding mechanism of the torsion bar cables.

The task to which the group of inventions is directed is to modernize the existing structures of sectional overhead ceiling doors.

The main single technical result that can be obtained by implementing the claimed group of inventions is to reduce the dimensions of the product in order to use them for openings with a very low lintel, as well as reduce the cost of the product by reducing the complexity in the manufacture of its structural elements, during assembly and installation nodes.

The specified single technical result for the object, the guide system of the presented group of inventions is achieved due to the fact that the system of guides of sectional lifting gates consists of pairs of vertical guides combined with corner posts that are mounted on both sides of the aperture (hereinafter referred to as combined vertical guides), each of which is a single lengthy profile with a number of grooves and / or holes in its lower part to adjust the tension supper block - cable mechanism for balancing the gates, each connected by double bending of the guides with the corresponding double horizontal guide, made each of a single long profile, consisting of two identical long shelves of C-shaped section with guide surfaces, the upper of which is the guide for the rollers of the upper panel the door leaf, and the bottom for the rollers of the door leaf panels, with the exception of the uppermost one, while the double bend of the guides consists of two bends ibs, the lower of which serves to smoothly connect the long shelf of the combined vertical rail with the lower shelf of the double horizontal rail, and the upper bend is the final element of the upper shelf of the double horizontal rail; a connecting bracket that provides a smooth connection of bends with the shelves of the double horizontal guide, and which is joined to the combined vertical guide of the wall mounting bracket in the form of an angular profile, in the lower part of the ribs of which, due to its contour cutting, the side walls of the profile are bent inward so that the section this profile in its lower part corresponds to the part of the cross-section of the profile of the combined vertical guide, and the mounting bracket to the double-bend wall guides It is used for the subsequent installation of a terminal double pulley bracket blochnotrosovoy spring balancing system or the gate terminal supporting bracket installation shaft torsion mechanism equilibration gate.

The vertical rail used in the claimed design of the gate combined with the corner post is a single cold-rolled steel profile combining the functions of a vertical guide for the door leaf rollers and the corner post, which provides rigidity of fastening to the walls of the guide system (single guide system). The combination of a vertical guide and a corner stand in one profile allows you to increase the aesthetics of the appearance, as well as eliminate the design flaws, manufacturing and installation techniques that are typical for prefabricated individual vertical guides with corner posts by eliminating the connecting elements (plates and brackets) needed to assemble the corner racks and vertical rails, as well as exceptions from the manufacturing process for the assembly of vertical rails and corner racks by gluing yvaniya or welding or connection using bolts and nuts;

eliminating the distortion of the end faces of the door leaf relative to each other, as well as the distortion and deformation of the door leaf when moving along the guides by eliminating the difference in the angles of inclination of the right and left vertical guides.

The combination of a vertical rail and an angular rack also leads to a decrease in the overall dimensions of the construction of the combined vertical rail compared to the prefabricated structure (vertical rail with an angular rack), and, consequently, the dimensions of the gate, which use a system of rails with combined vertical rails.

Strict parallelism of the guide (the guiding surface of the long shelf (C-shaped part) of the profile) the surface guiding the roller when moving) and the supporting (the supporting surface of the profile attached to the wall) profile surfaces of the combined vertical guide, as well as the high accuracy of their relative position, characteristic for profiles made by the rolling method, when mounting the gate, they ensure mutual parallelism and arrangement in the same plane of the trajectories of the rollers from both end faces along otna gates without additional control operations and mutual alignment location nodes (rollers disposed in two vertical guides on both sides of the door leaf), a system of guides that (operations) are necessary before the fastening system of guide elements against the walls of the room. The straightness and verticality of the combined vertical guide provide a strictly vertical movement of the web rollers along the guides when the gate moves, which reduces the power loss of the gate balancing mechanism due to the friction of the rollers against the vertical guides.

As a rule, the supporting (wall-mounted) surface of the combined vertical rail and the bracket for attaching to the double-bend wall of the guides have edge bends

- 3 022940 for the installation of a side seal providing tight sealing of gaps between the door leaf and the combined vertical guide along the entire height of the sides of the opening.

The use of a double horizontal guide in the form of a single profile allows, as in the case of a combined vertical guide, to eliminate the design flaws, manufacturing and installation techniques that are typical for horizontal guides assembled from individual profiles using connecting plates or brackets, namely: to exclude connecting elements (plates and brackets, bolted, riveted and welded joints) necessary for fastening sections of horizontal guides to each other, and from CA production exclude assembly operations double guides.

The presence of special longitudinal grooves inside the long shelves of uniform profiles of combined vertical guides and double horizontal guides for placing the heads of fasteners in them, necessary for assembling the guides with other structural elements of the guide system, reduces the likelihood of grazing the web rollers over the protruding parts of the connecting elements (screw heads) in the movement of the rollers along the guides. Additional places for bending profiles that occur during the manufacture of gutters increase the rigidity of the guides.

The wall mount bracket for the single rail system, designed to mount the bends assembly with the combined vertical rail and double horizontal rail to the wall, is an angular profile. Contour (profile cut along the edge from bottom to top and then transverse to the cut notch) open the ribs in the lower part of the corner profile and bend the side walls into the profile so that the section of this profile in its lower part corresponds to the part of the profile section of the combined vertical guide, serve to create space for free movement of the cable for hanging the door of the spring block - cable mechanism for balancing the door from the inside of the combined vertical rail to its outside, sidewalls profile with provide precise positioning of the lower bending the double bending guide with a combined vertical guide.

In the particular case of the system of guides, each of the combined vertical guides can be made integral from the bottom of a single long profile with a number of grooves and / or holes for adjusting the tension of the spring block-cable mechanism for balancing the gate, and the upper part of a single long profile of a combined vertical attached to it guide without similar grooves and / or holes. The use of a composite combined vertical rail is beneficial for optimizing the production and warehouse logistics of small enterprises in the storage and manufacture of gates with various options for balancing mechanisms from a minimum number of components. This advantage is relevant only if there is no specialized stamping equipment and tooling in a small enterprise.

In addition, a hole can be made on the side surface of the bracket for fastening to the double-bent wall of the guides for temporary fixation of the lower ends of the cable of the spring block-cable mechanism for balancing the gate, which is used when the door balancing mechanism is delivered to the mounting object in a state assembled with a vertical guide and an angle pillar .

The design feature of the double-bent guides is also the possibility of its use, both assembled with the end support bracket for installing the shaft of the torsion gate balancing mechanism, and assembled with the end bracket for attaching the double pulley of the spring block-cable balancing system, that is, regardless of the type of ordered the gate.

Thus, the claimed system of single guides is universal, i.e. applicable to any type of gate, regardless of the system used to balance the gate. At the same time, both modifications of the double bend of the rails assembled with the wall mount bracket are assembled at the production site by the method of contact or relief welding with the subsequent application of a protective and decorative paint and varnish coating and are delivered for installation in the form of single assembly units. Installation of the combined vertical rail is carried out in conjunction with a double bend of the rails.

The described design of double-bent guides is used as part of a door with a system of guides made of uniform profiles, but the application of the principles embodied in this design is also possible in assembly units of double bends of traditional systems of guides of sectional lifting gates.

A single technical result for the first (gate with a spring block-rope mechanism for balancing the door leaf) of the declared door variants is achieved due to the fact that the sectional lifting gate for a low lintel contains a supporting frame with a guide system and a horizontal crossbar installed above the upper edge of the gate; consisting of several horizontal panels arranged in series and pivotally connected to each other and moved by means of rollers located on the sides of the canvas sheet between the closed and open positions in the guiding system of the door leaf and the spring block-cable system for balancing the gate, which consists of a pair of vertically mounted on both sides of the opening on the outside of the combined vertical guide blocks of twin springs, two cables with ends fixed to the corresponding lower corner brackets of the bottom gate panel, and a pair of end brackets of double pulley fasteners, each mounted on a wall bracket of the corresponding double-bend guides of the guide system; moreover, each of the double spring blocks consists of two coaxially located extension screw springs, the inner of which has an outer spiral diameter smaller than the spiral inner diameter of the outer spring, the upper end with an integrated double pulley and the lower end, which is fixed in one of the grooves or holes at the bottom of the combined vertical rail, and mounted vertically outside the combined vertical rails on both sides of the opening so that the cable is fixed which is located on the lower corner bracket of the lower gate panel, passes from the inside of the combined vertical guide, bending around the double pulley of the end bracket of the double pulley, onto its outer side, goes down, forming a loop that winds behind the pulley of the upper end of the twin spring unit, unfolds, rises up and fixed on the end bracket of the double pulley, which is mounted on the bracket to the wall of the double bend guides of the guide system, which consists of located on both sides of the opening and intended for fastening to the wall, pairs of vertical guides combined with corner posts, each of which is a single lengthy profile with a series of grooves or holes in its lower part for adjusting the tension of the spring block-cable mechanism for balancing the gates, each connected by double-bent guides with a corresponding double horizontal guide made each of a single lengthy profile consisting of two and identical long C-shaped shelves with guide surfaces, the upper of which is the guide for the rollers of the upper panel of the door leaf, and the lower one for the rollers of the door leaf panels, except for the upper one, while the double bend of the guides consists of two bends, the lower of which serves for smooth connection of the long shelf of the combined vertical rail with the lower shelf of the double horizontal rail, and the upper bend is the final element of the upper shelf of the double horizontal rail auspicious; a connecting bracket that provides a smooth connection of bends with the shelves of the double horizontal guide, and which is joined to the combined vertical guide of the wall mounting bracket in the form of an angular profile, in the lower part of the rib of which, due to its contour cutting, the side walls of the profile are bent inward so that the cross section of this profile in its lower part corresponds to the part of the profile cross section of the combined vertical guide.

A single technical result for the second (gate with a torsion mechanism for balancing the door leaf) of the declared door variants is achieved due to the fact that the sectional lifting gate for a low lintel contains a supporting frame with a guide system and a horizontal crossbar installed above the upper edge of the opening, consisting of several consecutively located and horizontal panels pivotally connected to each other and moved by means of rollers located on the sides of the panels of the canvas overhead between open and open positions in the guiding system of the door leaf and the gate balancing system, consisting of a torsion gear comprising a shaft with at least one torsion spring mounted on bearings mounted on the corner posts of the end support brackets, one end of which is fixed to the shaft and rotates together with a shaft, and the other is fixedly fixed to the wall using the internal support bracket, and with a pair of drums rigidly fixed at its ends, winding the cable around itself when the shaft rotates, insulated on the lower corner bracket of the door leaf, and pairs of end support brackets for installing the torsion shaft, each mounted on the wall mounting bracket of the corresponding double bend guide system, which consists of pairs combined on both sides of the opening and designed for mounting on the wall with corner posts vertical guides, each of which represents a single lengthy profile with a series of grooves and / or holes in its lower part, connected by each by double bending the guides with the corresponding double horizontal guide, each made of a single long profile, consisting of two identical long shelves of C-shaped section with guiding surfaces, the upper of which is the guide for the rollers of the upper panel of the door leaf, and the lower one for the rollers of the door panel the gate, with the exception of the uppermost one, while the double bend of the guides consists of two bends, the lower of which serves to smoothly connect the long shelf combined th vertical guide with the lower shelf of the double horizontal guide, and the upper bend is the final element of the upper shelf of the double horizontal guide; a connecting bracket that provides a smooth connection of bends with the shelves of the double horizontal guide, and which is joined to the combined vertical guide of the wall mounting bracket in the form of an angular profile, in the lower part of the ribs of which, due to its contour cutting, the side walls are bent inside 5 5,92940 fillets so so that the cross section of this profile in its lower part corresponds to the part of the profile cross section of the combined vertical guide.

The possibility of completing the gate with one of the types of balancing mechanism without changing the design and composition of the door leaf, as well as the structural elements of the guide system, which is an exceptional feature of sectional lifting doors with the proposed system of single guides, ensures maximum efficiency in organizing the production of such doors, their storage and logistics.

The installation of a horizontal bolt connected to the combined vertical guides over the upper edge of the opening in the declared door variants, as well as the above features of the applied guide system, serves to reduce the lintel required for mounting the door without compromising the tightness of the joints between the door leaf and the door opening contour in their closed position. The tight overlap of the gaps between the door leaf and the combined vertical rail along the entire height of the sides of the opening is ensured by the fact that the plane of contact with the horizontal crossbar wall, the supporting surface of the combined vertical rail and the bracket for attaching to the double-bent wall of the single rail system have edge bends for installation side seal.

In any of the claimed door variants, for thermal insulation of metal elements of the guide system located (elements) in close proximity to the opening, a side seal is used, mounted on the edge bend combined with a vertical guide and then on the bend of the wall mount bracket assembly with double bend guides, containing the castle part formed by bracket-shaped shelves, a rigid hollow body, formed by two walls perpendicular to the shelves of the castle part, and soft cakes ok considerable length. The proposed design of the side seal provides a high degree of tightness (tight overlap of the air flow from the outside to the inside) between the door leaf and the border elements of the opening along its entire contour of the opening, increases the corrosion resistance of the steel elements of the border of the opening and the elements, and also increases the structural strength in the area of the side seal. Installation of the side seal profile at the installation site is complete with a combined vertical rail. Assembly of the side seal with the specified vertical rail is carried out in the conditions of production of elements of the guide system or before installation.

Numerous existing analogues of side seals from other manufacturers do not have the full set of the above properties of the described side seal and leave the metal parts of the guide system elements open or cover these metal parts with a thin layer of plastic, not providing sufficient thermal insulation between the outer and inner spaces of the installation object.

Thus, the proposed design of the gate according to both of the claimed options allows to achieve a high degree of sealing of the joints of the web with the frame elements of the aperture (single vertical guides and the upper horizontal crossbar) using a special side seal. This ensures thermal insulation along the contour of the opening of the elements (combined vertical rails, wall mounting bracket assembly with double bending rails and horizontal crossbar) of the rails system.

The use of the claimed system of guides is possible when installing special supports and brackets on the door leaf with fasteners fixed in roller holders with the possibility of adjusting the position on the three axes of the rollers: side supports of the middle panels of the canvas, lower corner brackets of the lower panel of the canvas, upper corner brackets of the upper panel of the canvas. Installation of side supports, upper and lower corner brackets on the door leaf panel is carried out under production conditions before packing the gates, which increases the convenience and accuracy of their installation, reduces installation time, unlike the widely used methods for installing lower corner brackets for installation. In the door variants of the claimed design, the side supports are recessed inside the panels so that they practically do not protrude above the plane of the panels and they can even be closed with the protection profile of the roller movement zone (protection profile of the combined vertical rail).

The indicated (vertically outside the combined vertical guides on both sides of the opening) arrangement of the spring block-cable mechanisms for balancing the gate in combination with the end brackets for fastening the double pulleys of the balancing system together with the double bends of the guides of the system of single guides allows you to assemble the spring block-cable system for balancing the doors with combined vertical rails fully in production conditions, pre-tension of springs;

temporarily fix the assembled cable in the holes of the double bends of the guides using a bolted connection in the position corresponding to the closest position of the axis for fixing the cable to the door leaf;

in a fully assembled state, deliver a balancing system to the installation object,

- 6,022,940 significantly reducing the number of installation operations of the system.

For the gate model used in the door model according to the first declared variant of the spring block-cable system for balancing the gate, the following manufacturing of structural elements is preferred:

1) Use of coil springs with the same winding direction.

2) The implementation of the legs, on which the ends of the coaxial springs forming one spring unit, the scissor-shaped arms of the upper and lower ends of the springs are sliding and sliding. A reliable fit of the coil of the springs in the engagement zones with the sections of the scissor-shaped brackets is also additionally ensured by pressing the ends of the spirals of the springs against the edges of the scissor-shaped bracket as a result of the separation of its movable part relatively motionless.

3) The execution of the ends of the springs with scissor-shaped brackets, and each leg of the scissor-shaped brackets so that it has a finite narrow mounting section with paired hook-shaped multidirectional protrusions for mounting the internal spring and a wider mounting section adjacent to the first narrow mounting section from the opposite side from the springs protrusions for attaching the outer spring. Using this design of the spring ends allows you to reduce the complexity of assembling a block of twin springs, eliminating the operation of screwing the end or its latch into a double spring, and the presence of hook-shaped protrusions provides a more accurate location of the coil of the spring in the engagement zone due to the multidirectional protrusions in the pair, and also reliably prevents the removal of the springs .

4) Implementation of the end bracket for fastening double pulleys of interconnected bases with a fixed lock for the loop loop of the balancing system of the gate, plate and parallel to the wall plane on the axis of the double pulley between them.

Operational safety in the declared door variants is ensured by:

protection of the movement zone of the rollers (protective profile of the vertical guide) for any type of balancing mechanism;

protection of the zone of movement of the tension spring (gate with a spring block-cable mechanism for balancing the gate);

preventing the spring of the torsion mechanism from breaking (the gate with the torsion mechanism of balancing the gate).

A set of profiles (profile for protecting the zone of movement of the rollers (profile for protecting the guide) and a profile for protecting the zone of movement of the spring (helical tension spring of the spring block-rope balancing mechanism)) are used to prevent people and foreign objects from entering the zones of movement of the elements (tension springs and roller bearings with rollers) the gate, as well as to ensure the soundless operation of the movable gate units in the area of the combined vertical guides and the attractive appearance (aesthetics) of the door t indoors.

Thus, the claimed gate designs, regardless of the type of balancing mechanism used in them, can be additionally equipped with long-length protection profiles for the roller movement zones mounted on combined vertical rails.

Known structural elements (protective plastic washers or screens on rollers, side covers of door panels with shaped bends located above the vertical guide) protecting the movement zone of the rollers, which are installed on the movable elements of the door leaf and during operation of the door also create a risk of injury person. The profiles of protection of the zone of movement of the rollers installed on the combined vertical guide rails remain motionless during the operation of the gate, thereby providing constant protection.

The profiles of the protection zone of the movement of the rollers of the L-shaped section can be used, consisting of each horizontal spring shelf, which, when the profile is mounted on the combined vertical rail, is parallel to its supporting surface and serves to overlap the space between the door leaf and the edge of the combined vertical rail and the vertical shelf which is in contact with the flat surface of the long shelf of the combined vertical rail, while the hard thrust hook with internally the sides of the profile of the protection of the movement zone of the rollers, abutting against the outer surface of the edge of the profile of the combined vertical guide, ensures the accuracy of the positioning of the protection profile of the movement zone of the rollers relative to the specified guide, and the teeth on the outer surface of the vertical shelf of the profile serve to position it without slipping and shifting relative to the protection profile of the tensile spring during installation.

Gates (the first option) with a spring block-rope system for balancing the gates can be equipped with protection profiles for the zone of movement of the springs. There are no analogs of the protective covers of the vertical tension springs for sectional lifting gates due to the fact that when the gate is opened and closed, the springs are compressed or stretched, and the upper movable ends of the springs move with them.

- 7,029,940

As profiles for protecting the movement zone of the springs, profiles can be used, each consisting of two multidirectional vertical shelves connected by a horizontal bridge, one of which, when installing the profile, is perpendicular to the supporting surface of the combined vertical guide, while the teeth of the second vertical shelf engage with the teeth applied on the outer surface of the vertical shelf profile protection zone of movement of the rollers.

The protection profiles for the roller movement zone and the protection profiles for the spring movement zone can be used either as a set of protection profiles or individually, depending on the presence or absence of tension springs in the door structure. The use of this set of profiles provides high security for operating the door in domestic conditions and allows you to be in close proximity to moving gates.

Protection profiles are made by extrusion from plastic mixtures with a hardness of at least 90 Shore or from other materials that provide noise absorption of moving rollers and springs, resistance to aggressive environments of domestic origin (gasoline, oil, dirt) and an attractive appearance of the product.

The gates according to the second declared variant, having a balancing system for gates with a torsion mechanism, can be additionally equipped with a spring burst protection device, which in a particular case consists of a housing that has concentric grooves to allow the movement of the bolts of the stationary end of the torsion spring torsion mechanism, pressed in the housing a rolling bearing for free rotation of the spring assembly with the end in the event of a break in the spring and an arm for attaching the housing to the ends th support shaft mounting bracket; fixed on the shaft of the torsion mechanism of the ratchet wheel, as well as motionlessly attached to the wall of the housing mounted on the axis of rotation together with a small torsion spring jamming element in the ratchet wheel.

The design features of the said spring burst protection device also make it possible to reduce the overall dimensions of this device to such an extent that when it is mounted on the torsion shaft above a horizontal crossbar connected to combined vertical rails in a rigid frame, the lintel height of the sectional lifting gate with a balancing mechanism located above the doorway, reaches no more than 135 mm, which is significantly less than existing analogues of other manufacturers.

That is, the device of the traditional type with the classical principle of operation is arranged in such small dimensions that allow the use of this protection device on gates with torsion springs with a diameter of 45-50 mm and with a lintel 135 mm. In addition, tests showed that the gate when the spring breaks when using such a device for protection against spring breaks fall by 3-4 cm. European safety standards require that the gate fall in case of an accident should be no more than 30 cm. This ensures safety guarantee with almost ten times the excess of European standards.

Raising and lowering the gate can be done manually or using an electric drive. For manual control, use handles attached to the door leaf, as well as a rope or gear driven by a chain. In the claimed door variants, a chain ceiling electric drive can be used, consisting of an electric motor and a remote control unit, which is mounted on the wall in any convenient place and combined into a single structural unit with sectional doors.

Separate placement of the electric motor from the control unit makes it possible to significantly reduce the size of the drive structure installed directly on the ceiling of the room. This, in turn, allows you to automate sectional doors in a room in which it was previously impossible to do this due to the minimum size of the lintel.

All currently known chain ceiling electric drives for sectional doors are mounted on the ceiling in the center relative to the width of the doors and have their own mounting brackets, which complicates the installation process and increases it over time. Installing an electric motor directly on the horizontal guides of a sectional door allows you to supply the customer with an finished product assembly directly from the manufacturer. This solution significantly saves time on installation and does not require additional space on the ceiling of the room and additional fasteners.

The used electric motor, as a rule, is closed by a decorative case made of high-strength plastic with a glossy texture, which does not allow atmospheric dust to accumulate on the surface of the case, and also reduces external maintenance efforts to a minimum. The control unit of the electric motor with the control panel by the operation of the electric motor is placed in a separate structure and can be installed in any convenient place on the wall of the room. This solution has several advantages relative to the analogues available on the market, in which the drive operation settings panel is located directly on the drive housing located on the ceiling:

easier access to the control panel, which simplifies the process of setting up the operation of the electric motor and

- 8 022940, respectively, significantly saves time in setting up the drive;

allows the installation of the unit in the heated part of the building, which increases the stability of the electric motor located in the unheated part of the building.

The control unit, as a rule, is equipped with a built-in electric motor control button located on the front panel of the control unit housing and designed to control the drive from the inside of the room. This solution does not require additional installation of an external control key, which facilitates installation and saves time. The control button can be made with a highlighted circuit, which greatly facilitates the control of the drive in a dark room.

Possible special cases of execution of the control unit housing:

equipping the body with a backlight designed to illuminate the room at the time of opening the gate - to facilitate orientation in the room without first turning on a centralized light source;

the case is made of high-strength white plastic with a glossy texture - the neutral design of the case allows you to install the control unit in any place without violating the overall design concept.

When using an electromechanical drive for raising and lowering the blade, it is proposed to use a lateral drive with a mounting system for the drive carriage guide to a single double horizontal guide and with mounting the drive rod to a special upper corner bracket with an adjustable roller holder and with an adapter for attaching the drive rod.

Locking gates that do not have an electric drive is carried out using a spring bolt or bolt lock. The crossbar lock allows you to lock the gate both inside and out. Deadlocking can only be done from the inside.

The whole complex of nodes connected according to the proposed scheme allows you to realize the customers need for gates for installation objects:

with a very low lintel i.e. with a very small distance from the top edge of the doorway to the ceiling;

the need for insulation of joints and, as a result, energy conservation;

the need for safe operation and attractive appearance of the product with a minimum cost of the product and its installation.

Reducing the number of nodes and parts coming to installation as part of a single set of gates, allows to ensure high quality assembly of individual nodes in production through the use of welded joints of elements instead of bolts, by applying a protective and decorative coating of all elements of the assembly, and reduces the complexity of installation works due to the exclusion of the operations of connecting individual parts of the gates to enlarged units directly at the installation site. The proposed design of the gate solves a number of problems to reduce the cost of the product by reducing the metal consumption of the nodes, the number of assembly operations, as well as the number and complexity of installation operations.

Below, in the examples of the description of the specific design of sectional lifting gates for a low lintel with a spring block-rope door balancing system (example 1) and the design of the spring burst protection device (example 2) of a door with a torsion gate balancing mechanism, information is provided confirming the possibility of the claimed group inventions with a single technical result.

Example 1

Sectional lifting gates (Fig. 1) for a low lintel consist of a door leaf 1, a supporting frame (Fig. 2) with a single guide system and a horizontal crossbar 2 and a gate balancing system with a spring block-rope mechanism 3.

The door leaf 1 consists of several horizontal panels (sections) arranged in series and pivotally interconnected by loops, which are hot-galvanized steel double-walled sandwich panels with polyurethane foam filling the internal cavity. The canvas moves from a vertical (closed) position to horizontal (open) as a result of movement and direction of the web panels in the system of single guides by means of rollers located on the sides of the panels.

The system of single guides is (Fig. 2) a prefabricated structure of two combined vertical guides 4, each connected by double bends 5 with the corresponding double horizontal guides 6.

Each combined vertical guide 4 of the guide system is made (Fig. 3) in the form of a single steel cold-rolled long profile, the cross-section of which is L-shaped (angular stand, angular profile) and C-shaped (straight guide) parts connected to each other. The profile has a supporting surface 7 attached to the wall located on the L-shaped part, which is strictly parallel to the guiding surface (the surface in contact with the roller and guiding it when moving) 8 of the long shelf (C-shaped part) of the profile, inside which a longitudinal groove 9 is made for placing in it guides used for assembly with other structural elements of the guide screw system. In the lower part of the combined vertical guide, on a surface that is perpendicular to the supporting surface of the profile, there are a series of rectangular grooves 10 and holes 11 for adjusting the balancing of the mass of the door leaf after the installation of the gate. It is allowed to use a composite combined vertical rail (Fig. 3 c) in the gate design as a part of a combined vertical rail of small length 12 with rectangular grooves 10 and holes 11 connected using a connecting plate 13 to a measured piece of the combined vertical rail 14 without similar grooves and holes. A single profile for a combined vertical rail is made by roller rolling from cold-galvanized steel strip with a thickness of 1.4-1.5 mm, followed by applying a protective and decorative coating by cold galvanizing or powder painting. The installation of the combined vertical rail is carried out in conjunction with the double bending of the rails assembled with the wall mount bracket and consists in installing the assembly assembled at the production site to the walls, aligning the combined vertical rails to the vertical level and fastening the assembly to the wall with screws.

The double horizontal guide (Fig. 4) 6 of the guide system is a single steel cold-rolled hot-dip galvanized profile, in which two identical profiles 15 are used, which are used structurally: the lower one as a guide for the rollers of the door leaf panels, excluding the uppermost one; upper - for rollers of the upper panel of the door leaf. Each of two identical profiles (long guide rails) of the C-shaped section has guide surfaces 16 and longitudinal grooves 17 for accommodating the heads of the fasteners necessary for assembling the double horizontal guide with other structural elements of the guide system and attaching the double horizontal guide to the ceiling of the installation room.

Additional rigidity is given to the profile of the bending point 18, formed as a result of the manufacture of the gutter.

A single profile of a double horizontal guide is made by roller rolling from cold-galvanized steel strip with a thickness of 1.4-1.5 mm, followed by applying a protective and decorative coating by cold galvanizing or powder painting. The installation of a double horizontal guide consists in installing on the horizontal bracket for fastening a single horizontal profile cut to size in the production of a double horizontal guide with holes previously made in it for attaching to the connecting elements of the guide system, aligning the profile to the horizontal level and attaching it to the bracket for attaching the double horizontal guide to the wall, to the bracket for fastening the double horizontal guide and C-profile and to the bracket the ceiling mount.

The double bending of the guides (Fig. 5) 5 is an assembly of the system of single guides and consists of two curved elements (hereinafter bends) 19,20, a connecting bracket 21 and an arm for attaching to the wall 22.

These curved elements are intended:

the lower bend (arc) 19 serves to smoothly connect the combined vertical rail with the lower shelf of the double horizontal rail to form a guide for the rollers of the door leaf panels, excluding the uppermost one;

upper bend (the bend profile has a first section that is slightly inclined to the horizontal, and a second section that is slightly more than 90 ° to the horizontal is bent towards the floor) 20 is the final element of the upper shelf 15 of the double horizontal rail and completes the upper shelf of the double horizontal guide so that it is possible to adjust the position of the upper roller depending on the manual method of opening and closing the gate or opening and closing using an electromechanical drive a.

The connecting bracket 21 with flat punchings and with a group of holes provides a reliable and smooth connection of bends 19.20 with a double horizontal guide.

The bracket for mounting to the wall 22, which is a structural element of the assembly unit, the double bending of the guides, is an angular profile with two mutually perpendicular side walls and with grooves for mounting the bracket to the wall, with an edge bend 23 for installing the side seal, which provides a tight overlap of the gaps between the web the gate and the combined vertical guide along the entire height of the sides of the opening (the edge bend on the corner post is identical to the edge bend of the supporting surface STI combined vertical guide), and the flat vyshtampovki to ensure its docking with a combined vertical track (with L-shaped profile part of the combined vertical guide). In the lower part of the angular profile of the wall mount bracket as a result of contour cutting of the rib and bending into the profile of its side walls, a space 24 is formed for the free movement of the suspension cable of the door of the spring block-cable mechanism of balancing the gate. For temporary fixation of the lower ends of the cable, which are moored during operation of the gate to the steel thimbles of the lower corner bracket of the lower gate panel, a hole 25 is made on the side of the profile. The double bending of the guides used is used together with the end bracket for mounting the double pulley 26 of the spring block-cable balancing system .

The door leaf is moved along the guides with the help of rollers (Fig. 1) fixed in the roller holders of the side supports 27, lower 28 and upper 29 corner brackets.

To ensure the movement of the middle panels of the door leaf in the guide system, lateral supports are provided with adjustable roller position along three axes. Each side support (Fig. 6) has a base 30 located perpendicular to the base and turned inwardly between the end of the door leaf and the combined vertical guide rails 31 with a roller holder 32 mounted on it with a roller 33, the axis of which can be longitudinally moved in the cylindrical channel of the roller holder, and grooves 34 for adjusting the position of the roller holder with the roller in the guides. Installation of side supports on the middle panels of the door leaf is carried out in the conditions of production before packing the product.

To move the lower panel of the door leaf in the guide system and to secure the lifting cable of the balancing mechanism of the door at the lower point of suspension of the door leaf, it is possible to install a lower corner bracket 28 on the lower panel of the door leaf with adjustment of the roller position in three axes. The lower corner bracket (Fig. 7) has a base 35 located perpendicular to the base and turned inward between the end of the door leaf and the combined vertical guide rails 36 with the roller holder 37 mounted on it with the roller 38 and the suspension axis 39 of the lifting cable.

The presence of grooves (not shown) on the shelf of the bracket allows you to adjust the position of the roller holder with the roller in these guides, and the axis of the roller can be moved longitudinally in the cylindrical channel of the roller holder. The installation of the lower corner brackets on the lower panel of the door leaf is carried out under production conditions before packaging the product.

To ensure the movement of the roller of the upper panel of the door leaf along the upper bend and along the upper horizontal guide on the upper panel of the door, the upper corner brackets 29 are installed with the roller position adjusted in three axes. Each such bracket (Fig. 8) has a base 40 located perpendicular to the base and turned inward between the end of the door leaf and the combined vertical guide rails 41 with a roller holder 42 mounted on it with a roller 43, the axis of which can be moved longitudinally in the cylindrical channel of the roller holder 42, and with slots 44 for adjusting the horizontal displacement of the roller holder. The grooves 45 on the roller holder are made to adjust its vertical position. The rib 46 made on the roller holder 42 increases the flexural strength of the latter when shock and dynamic loads occur during the movement of the door leaf along the guides. The installation of the upper corner brackets on the upper panel of the door leaf is carried out under production conditions before packaging the product.

The used designs of side supports, upper and lower corner brackets of the upper corner bracket allow:

a) due to the mutually perpendicular arrangement of the base of each side support / corner brackets with its shelf, turned inward to the space between the end of the door leaf and the combined vertical rail, position the rollers in the space between the end of the door leaf and the combined vertical rail;

b) using the grooves located on the shelves, adjust the position of the roller holder with the roller in the guides to approximate or remove the door leaf from the wall, thereby ensuring tightness of the seal along the contour of the door leaf to the wall;

c) the rollers move freely along their axis in the cylindrical channels of the roller holders, independently compensating for the skew in the installation of the guide system.

In order to seal the joint between the door leaf and the gate opening contour in their closed position above the upper edge 47 of the opening, a horizontal bolt 2 is installed (Fig. 9), on the longitudinal bend 48 of the abutment plane to the wall of which a side seal 49 is attached (latched). Horizontal bolt for fastening the side seal over the upper edge of the doorway, it is made by roller rolling from a cold-galvanized strip with a thickness of 1.4-1.5 mm, followed by applying a protective and decorative coating by the cold method th galvanizing (vozmozhnoporoshkovogo staining). The installation of a horizontal crossbar together with a side seal pre-installed on it consists in its fastening with self-tapping screws to the wall above the upper edge of the gate opening.

The same side seal (Fig. 3, 5, 10), mounted on the bend 50 of the combined vertical rail and the identical bend 23 of the bracket for attaching to the double-bent wall of the guides, is used to seal the gaps between the door leaf and the elements of the edging around the opening, preventing the penetration of air from outside the room into.

A design feature of the used side seal profile (Fig. 11) is the presence of a lock formed by two bracket-shaped shelves (profile lock part), a rigid hollow body formed by two walls 52 perpendicular to the lock part shelves 51, and a soft petal 53 of considerable length, which ensures a tight overlapping gaps between the door leaf and the elements of the edging of the opening along the entire contour of the opening. An internal jumper 54 between the walls divides the housing into two parts to form air chambers 55 (cavities). The side seal profile is made by coextrusion of two polymeric materials, one of which has a hardness of at least 90 Shore A and the other has a hardness of not more than 70 Shore A. The thickness of the plastic profile of the seal is at least 2.5 mm.

The spring-loaded block-rope gate balancing system (Fig. 12) consists of two doors located on the sides of the door leaf, outside of the combined vertical guides 4 double spring blocks 56 assembled with ends, a pair of end brackets for securing the double pulleys to the wall 26, fixed in the production environment to a pair of double bends of the guides and two steel cables 57 fixed with steel thimbles on the lower corner brackets 28 of the lower section 58 of the door leaf.

Each twin spring unit 56 consists (Figs. 13, 14) of two coaxial (springs arranged coaxially, one in the other) located extension coil springs 59 and 60, an upper end 61 with a built-in double pulley and a lower end 62 with a tongue for fixing the spring unit in rectangular grooves and holes in the bottom of a single vertical guide to regulate the tension of the spring block.

The inner spring 59 has an outer spiral diameter smaller than the spiral inner diameter of the outer spring 60, so that the springs can move independently of one another without the danger of the coils of one spring entering the gaps between the coils of the other. The outer spring is approximately 20 mm longer than the inner spring. The diameter of the springs and the diameter of the wire are selected depending on the mass of the web. Coils

- 12,029,940 of both springs have the same left-side winding direction in the same axial direction. The ends of both, forming one spring block of coaxial springs, are pulled and fixed on the expandable legs 63 of the scissor brackets 64 of the upper 61 and lower 62 ends of the springs. Each leg has a finite narrow mounting section with pair hook-shaped protrusions (teeth) 65 for attaching the inner spring and adjacent to the first narrow mounting section from the side opposite to the springs - a wider mounting section with pair hook-shaped protrusions 66 for mounting the outer spring. Paired hook-shaped protrusions on the edges of the legs of the scissor-shaped brackets interact with the thrust coils of the springs 59 and 60, preventing their removal.

Assembly of double coil springs with upper and lower ends of the springs is performed simultaneously in the following order:

a bolt connection 67 is removed from the scissor-shaped end brackets, the legs of the scissor-shaped spring end brackets connected to each other by a rivet with the possibility of free rotation around the axis of the rivet are shifted so that the width of both legs becomes smaller than the inner diameter of each of the springs;

the upper and lower ends of the springs with the legs of the scissor brackets are inserted into the double spring (from the one end of the double spring - the upper end, from the other end - the lower), when you press the protruding parts of the ends of the double springs, the legs of the scissor brackets move apart inside the springs and hook-shaped protrusions on the edges legs fall between the coils of the springs;

after installing the bolted connection to the assembled end, the teeth of the legs of the scissor-shaped brackets of the end are firmly fixed between the turns of the internal and external springs.

The spring-loaded block-rope system for balancing the weight of the door leaf is supplied to the assembly object with combined vertical guides and double-bent guides. The installation of the spring block-cable system consists in installing and attaching single vertical rails to the walls, moving the ends of the ropes moored on steel thimbles from the double bends of the guides to the lower corner brackets of the lower panel of the door leaf and adjusting the balancing of the weight of the door leaf. During installation, the ends of the cables with thimbles are fixed on the double bends of the guides with the help of bolts and nuts. After completing the installation of the guide system assembly with the spring block-cable system and the door leaf assembly with roller brackets, the door leaf is lifted along the guide rails to the upper horizontal position, the cables are removed from the double bends of the guide rails and secured to the axis of the lower corner brackets and fixed with a washer and forelock. The balancing of the mass of the web is regulated by moving the tongue of the lower bracket of the spring block along a series of rectangular grooves and holes in the lower part of a single vertical guide. The advantage of this web balancing system is the compactness of the system, which makes it possible to reduce the size of lintel 1ι to 80 mm.

The assembly assemblies of the end brackets of the double pulleys consist (Fig. 15) each of the base 69, the plate 70 and the double pulley 71 fixed to the wall and connected to each other by two contact welding points 72, axes 73 and 74, and also from the bracket mounted on the base by bolting the fixed lock 75 of the cable loop. Each of the end brackets of the double pulleys 26 is mounted on the bracket for fastening to the double-bent wall 22 of the guides in the conditions of production by the method of contact or relief welding. The location of the double pulley 71 parallel to the plane of abutment to the wall allows (Fig. 16) to transfer the cable 57, mounted on the lower corner bracket from the inside of the combined vertical rail to its outer side, where the cable falls vertically down, and the resulting loop of the cable winds up behind the upper end pulley springs 61 of the block of double springs 56, swings up and rises to a fixed latch 75, located on the base of the end bracket for mounting the double pulley next to the additional axis Compound 74 and the base plate of the end bracket dual pulley which provides the rigidity of the end bracket assembly dual pulley as a whole and prevents the load from the cantilevered spring block on the fixed retainer cable loop. The cable is fixed to the fixed lock by a clamping washer with a bolted connection.

In the gate construction under consideration, in order to (first of all) increase the safety of their operation, protection is provided (including from pinching the user's fingers) of two zones (the zone of movement of the rollers along the combined vertical guide and the zone of movement of the spring) with moving structural elements. A set of lengthy protection profiles consists (Fig. 17) of the profile of protection of the zone of movement of the rollers 76 and the profile of protection of the zone of movement of the spring 77.

The long-length profile of the protection of the movement zone of the rollers 76 (Fig. 17a)) has a L-shaped cross section and consists of two mutually perpendicular shelves having a radius mate. When installing this profile on a combined vertical rail, the long horizontal spring flange 78 of the profile is parallel to the supporting surface of the combined vertical rail and serves to overlap the space between the door leaf and the edge (zagi-13 022940 bom) of the combined vertical rail, the vertical shelf 79 of the profile is pressed against the combined vertical guide, and a hard thrust hook 80 profile, abutting against the outer surface of the edge (bend) profile combined vertical ikalnoy guide ensures positioning accuracy of the profile with respect to said guide. The teeth on the outer surface of the vertical shelf serve to adjust the relative position (positioning without slipping and displacement) of the profile with the profile of the protection of the tensile spring described below during installation.

The protection profile of the zone of movement of the spring 77 consists (Fig. 17b)) of a horizontal bridge 81 connecting two opposite multidirectional vertical shelves 82, 83 located at its edges and having a radial interface with the bridge. During installation, one of the vertical shelves of the profile is perpendicular to the supporting surface of the combined vertical guide, and the teeth 84 of the second vertical shelf are engaged with the teeth applied to the outer surface of the vertical shelf of the protection profile of the roller movement zone to position the profile without slipping and displacement, as well as ensuring adjusting the relative position of the profiles. With this spatial arrangement of the protection profile of the spring movement zone, a pocket is formed (the space between the supporting wall, the protection profile of the spring movement zone and the outer surfaces of the combined vertical guide), in which the spring is placed.

The installation of protection profiles on the installation site is carried out at the final stage of installation and consists in putting on (snapping) and then fixing the profile of the protection of the movement zone of the rollers on the profile of the combined vertical guide, and the protection profile of the movement zone of the spring is positioned on the protection profile of the movement zone of the rollers.

To raise and lower the blade, a lateral electromechanical drive is used (not shown in the drawings) with a mounting system for the drive carriage guide to a single double horizontal guide and with mounting the drive rod to a special upper corner bracket with an adjustable roller holder and with an adapter for attaching the drive rod.

The gates are mounted behind an indoor opening on brickwork, concrete, steel structures or a combination of these materials, or in an opening formed by walls of the above materials.

Example 2

In FIG. 18 is a perspective view of a sectional overhead gate for a low lintel with a single guide system and a gate balancing mechanism 85 with torsion springs (torsion gear) mounted on a cylindrical shaft (torsion shaft) that is mounted in end support brackets 86 installed (FIG. . 19) on the wall mounting brackets 22 of the double bends of the guide system. In this case, one end of each spring after it is cocked is fixedly mounted on the shaft, and the other end, called stationary, is fixed to the fixed support (to the wall). The force of balancing the gate occurs when cocking the springs, i.e. when tightening the coil springs. The rotation of the torsion shaft, carried out under the action of the elastic force of the coil springs, leads to the rotation of a pair of drums on which cables are wound or unwound to raise and lower the door leaf. The ends of the cables are fastened to the drums and to the door leaf on the axis of the lower corner brackets. Fastening to the drums is carried out by a locking screw, which clamps the cable in the hole passing through the massive part of the partition. Fastening to the door leaf is carried out at the suspension points on the axes of the lower corner brackets using steel thimbles. The advantage of this web balancing system is the compactness of the system, which allows to reduce the size of the lintel 1ι to 135 mm

The torsion spring torsion spring burst protection device (hereinafter referred to as the protection device) consists (Fig. 20) of two main parts: a ratchet wheel 87, which is fixedly mounted on the shaft of the torsion mechanism, and is fixedly attached to the wall of the housing 88 and mounted on the axis of rotation together with a small torsion spring with a jamming element in the ratchet wheel (hereinafter referred to as a latch). The ratchet wheel 88 has a key protrusion in the central hole and is mounted on the cylindrical shaft of the torsion mechanism with a diameter of 25.4 mm with a key groove and is fixedly fixed using the locking screw. The housing 88 of the protection device has concentric grooves 89 for the bolts of the stationary end of the torsion spring of the torsion mechanism (hereinafter referred to as the main spring) to move, the rolling bearing 90 pressed into the housing to provide free rotation of the spring assembly with the end in the event of a spring break and the bracket 91 with holes 92 for attaching the housing to the shaft support end bracket. The latch 93 in conjunction with a small torsion spring 94 is mounted on the axis 95 of the housing 88.

When using the main spring break protection device, the device body 88 is fixedly mounted to the wall, the stationary end of the main spring is installed together with the pusher 96 of the latch 93 on the bearing assembly of the device body so that the bolts of the stationary end of the main spring can be freely moved around the center of the bearing in within the grooves 89 of the housing. A cocked main spring (torsion spring) presses the bolt head to one end of the groove, which in turn turns the pusher

- 14,029,940

96, and the latch 93 with a special bend 97 of the pusher 96 is squeezed (out of engagement with the teeth of the ratchet wheel) from the surface of the ratchet wheel 87. When the main spring breaks, its stationary end is released from the elastic force of the main spring and, under the action of the elastic force of the small spring 94 of the latch 93, rotates around the axis of the bearing 90 all the way to the opposite end of the groove. The latch 93 under the action of a small torsion spring 94 rotates and engages with the teeth of the ratchet wheel. To unlock the engagement of the latch and the ratchet wheel during the repair of torn springs, the latch 93 is rotated by pressing the fingers on the stop tab 98 and its position is fixed with a cotter pin 99 from spontaneous movement. After replacing the emergency spring and cocking, the new cotter pin is removed and the spring break protection device is ready for operation.

The spring burst protection device used for the gate is designed to prevent the gate from falling when the torsion mechanism tear springs break with an inner diameter of 45 to 50 mm.
