Utility model includes:

1. door leaf;

2. bearing beam;

3. special bracket on the side opposite to the rollback side;

4. special bracket on the rollback side;

5. roller support;

6. roller support;

7. trailer roller;

8. supporting and lifting bracket;

9. bottom catcher;

10. top catcher;

11. roller limiter;

12. lifting lever.

Bearing beam 2 is made up of a split support beam, which is similar to typical support beams for retractable cantilever gates and square stiffening pipes. The stiffening pipe and the support beam are rigidly fastened to each other, forming a single carrier beam 2. In the "Gate closed" and "Gate partially open" positions, the carrier beam 2 rests on two special brackets 3, 4. The brackets 3, 4 are rigidly fixed to the pillars of the opening gate. The carrier beam with the lower surface of the stiffening pipe rests on the support ledges of the brackets 3.4 (section B-B). The shape of the bracket provides for the possibility of moving the carrier beam 2 inside the brackets vertically by 10-15 mm and freedom of movement of the beam in the horizontal direction, along the web on roller bearings. Two roller bearings 5,6 are rigidly attached to the upper generatrix of the door leaf 1, similar to typical roller bearings for retractable cantilever gates (Fig. 2, view A). The rollers of the roller bearings are inserted inside the split support beam. On the side of the rollback direction, the door leaf is equipped with an end support roller 7. The weight of the door leaf in the closed position is perceived, from the side of the rollback by the platform of the support-lifting bracket 8, through the roller 7 (Fig. 2, view E), from the opposite side - by the carrier beam through the roller support 5. From the displacement of the door leaf in the direction perpendicular to the opening movement, as well as to maintain the coaxiality of the movement of the door leaf relative to the carrier beam and the carrier beam relative to the leaf, a roller limiter 11 is installed on the carrier beam.

The utility model is characterized by three main provisions:

1. the gate is closed;

2. the gate is partially open: the door leaf is opened by moving - by rolling the leaf on roller bearings. In this position, it is possible to enter vehicles with a height restriction, in which the load-bearing beam acts as a limiter (passenger vehicles). The transfer from closed to partially open position is carried out by moving the web along the carrier beam towards the opening, either manually or using an electric drive. When the web is moved, the rollers roll inside the split beam, which is an integral part of the carrier beam;

3. the gate is fully open. To transfer to this position from the “partially open gate” position, the door leaf and the carrier are lifted vertically together with a lifting lever in a special support-lifting bracket, after which the carrier beam moves (rolls back) along the roller bearings. In this position, the entry of vehicles without height restrictions is possible.

Description

The utility model relates to the field of construction. The utility model relates to devices designed to restrict access to certain areas, namely, sliding prefabricated (sliding) gates, which can be widely used in individual residential and suburban areas, adjacent areas, warehouses, industrial facilities, garage cooperatives.

Depending on the methods of fastening the sliding canvas, there are:

gates on support rollers;

cantilever gates;

top hanging gate.

Sliding gates on supporting rollers have a guide beam along the fence. A retractable canvas is superimposed on it. It moves and is held vertically by means of a pair of rollers fixed on a pole. The main drawback is the constant contamination of the guide beam during operation and the need for its regular cleaning for the normal functioning of the gate. In addition, the location of the guide beam just above the level of the roadway creates some difficulties for the movement of vehicles through the gate.

Sliding gates with an upper suspension are known: the canvas is suspended from above to the carrier beam and moves along it by means of rollers. But in this case, there is a significant drawback: the height of the vehicle is limited.

The most common sliding cantilever gates, in which the door leaf console protruding beyond the opening, rests on two roller bearings installed on a single foundation. In the opening with the gate open, there are no restrictions either from above or from below. Sliding gates are known: utility model patents RU 197156 U1, RU 146285 U1, RU 205585 U1. The closest analogue is the utility model RU 205585 U1, publ. 07/22/2021, which describes sliding gates containing a leaf having a power guide in the lower part, made in the form of a hollow beam with a longitudinal slot located in the lower part of the guide, mounted on roller bearings, which are fixed on adjusting stands. The disadvantages of this design is the increased size of the door leaf, for their installation it is necessary to equip a significant foundation for the roller bearings, and in the winter season the roller bearings and the supporting beam of the door leaf fall under the snow cover, which leads to corrosion and mechanical wear.

The technical task of the proposed technical solution is the creation of sliding gates with an upper suspension, in order to exclude the impact of snow cover on roller bearings, reduce the size of the door leaf to the size of the opening, while with the possibility of moving the carrier beam in order to remove the restriction on the passage of vehicles to the protected area in height . The technical result, which consists in excluding the effect of snow cover on roller bearings, reducing the size of the door leaf to the size of the opening and the possibility of moving the carrier beam in order to remove the height limitation, is achieved by using a special design combination of the carrier beam, support brackets fixed on the pillars of the opening, door leaf with roller supports rigidly fixed to the upper generatrix, a support-lifting bracket with a lifting lever mounted on the carrier beam of the upper roller limiter, as well as an upper catcher, a lower catcher.

The utility model is characterized by three main provisions:

1. the gate is closed;

2. the gate is partially open: the door leaf is opened by moving - by rolling the leaf on roller bearings. In this position, it is possible to enter vehicles with a height restriction, in which the load-bearing beam acts as a limiter (passenger vehicles). The transfer from closed to partially open position is carried out by moving the web along the carrier beam towards the opening, either manually or using an electric drive. When the web is moved, the rollers roll inside the split beam, which is an integral part of the carrier beam;

3. the gate is fully open. To transfer to this position from the “partially open gate” position, the door leaf and the carrier are lifted vertically together with a lifting lever in a special support-lifting bracket, after which the carrier beam moves (rolls back) along the roller bearings. In this position, the entry of vehicles without height restrictions is possible.

In FIG. 1 shows a general view of the utility model in three positions.

Position 1 "Gate closed", Position 2 "Gate partially open", Position 3 "Gate fully open" Fig. 2 shows views and sections of individual elements of the utility model, the locations of which are indicated in FIG. 1.

1. door leaf;

2. bearing beam;

3. special bracket on the side opposite to the rollback side;

4. special bracket on the rollback side;

5. roller support;

6. roller support;

7. trailer roller;

8. supporting and lifting bracket;

12. lifting lever.

Bearing beam 2 is made up of a split support beam, which is similar to typical support beams for retractable cantilever gates and square stiffening pipes. The stiffening pipe and the support beam are rigidly fastened to each other, forming a single carrier beam 2. In the "Gate closed" and "Gate partially open" positions, the carrier beam 2 rests on two special brackets 3, 4. The brackets 3, 4 are rigidly fixed to the pillars of the opening gate. The carrier beam with the lower surface of the stiffening pipe rests on the support protrusions of the brackets 3, 4 (section B-B). The shape of the bracket provides for the possibility of moving the carrier beam 2 inside the brackets vertically by 10-15 mm and freedom of movement of the beam in the horizontal direction, along the web on roller bearings. Two roller bearings 5, 6 are rigidly attached to the upper generatrix of the door leaf 1, similar to typical roller bearings for retractable cantilever gates (Fig. 2, view A). The rollers of the roller bearings are inserted inside the split support beam. On the side of the rollback direction, the door leaf is equipped with an end support roller 7. The weight of the door leaf in the closed position is perceived, from the side of the rollback by the platform of the support-lifting bracket 8, through the roller 7 (Fig. 2, view E), from the opposite side - by the carrier beam through the roller support 5. From the displacement of the door leaf in the direction perpendicular to the opening movement, as well as to maintain the coaxiality of the movement of the door leaf relative to the carrier beam and the carrier beam relative to the leaf, a roller limiter 11 is installed on the carrier beam.

When the gate is moved from the “Gate closed” position to the “Gate partially open” position, the leaf rolls back on roller bearings along the carrier beam in the direction of rollback (can be done both manually and with the help of an electric drive). During the movement of the door leaf, its weight is perceived by the carrier beam through the roller bearings 5, 6. At the final stage of movement, the leaf is fixed by the lower catcher 9 and the upper catcher 10. The design of the catchers is similar to typical catchers for cantilever sliding gates, they are fixed on the fence post on the side of the rollback. When the leaf is fixed in the lower catcher, the supported part of the leaf moves up slightly, due to which the roller support 6 is unloaded from the weight of the leaf. Partially open position allows the entry of vehicles with a restriction on the height of the carrier beam (passenger vehicles).

In order to roll back the carrier beam - transferring the gate from the "Gate partially open" position to the "Gate fully open" position - the side of the door leaf under the roller support 5 is lifted by turning the lifting lever 12 in the support-lifting bracket 8. On the section C-C of Fig. 4, the thick line shows the lift lever before turning it, the thin dotted line shows the position of the lever after turning it. Lever 12 is pivotally fixed on bracket 8. In the process of turning, the small arm of the lever rests against the lower generatrix of the door leaf and, when the lever is turned by 90°, moves the leaf up by ~10 mm. Together with the leaf, the roller support 5 moves upwards, and through it the carrier beam inside the bracket 4. Thus, the weight of the door leaf, after turning the lever, is balanced at two points: at the point of the lower catcher 5, and at the point of application of the force of the small arm of the lever in lifting bracket. And the weight of the carrier beam, after lifting the door leaf with a lever, is shifted from the brackets 3, 4 to the roller bearings 5.6'. Thus, the carrier beam acquires the mobility of moving (rolling back) along the fixed door leaf 1 along the roller bearings 5, 6. The rolling of the carrier beam brings the gate to the “Gate fully open” position. This provision allows the entry of vehicles without height restrictions.

Closing the gate from the “Gate is fully open” position is carried out in the reverse order, the carrier beam 2 is rolled into the regular position on roller supports along the leaf 1, the carrier beam 2 is rolled up, by turning the lifting lever 12 to the initial position, the door leaf and, accordingly, the carrier beam are lowered onto the brackets 3, 4 After that, the gate is closed by moving the door leaf 1 along the carrier beam on roller bearings 5, 6.
