Abstract

The invention relates to construction and can be used to automatically return the doors of public buildings with a massive passage of pedestrians. The aim of the invention is to improve the performance characteristics by allowing the door to be locked in the open position. Sash 4 is installed on the axis of swing 3. The yoke consists of two tons of g 1, 2 and is connected to the frame through elastic elements 13, 14 and earrings 11, 12, having a sickle shape. On the swing axle 3, the traverse 8 is installed with the leads 9, 10. The supports 16, 17 are mounted on the frame, with which the shanks of the t, 1, 2 rocker arms interact. When the sash is opened, the ha 1 or 2 passes through the zero position of the elastic element 13 or 14.

The invention relates to building structures and can be used in industrial buildings, subways, etc. with a large flow of people passing in either direction of pedestrians or for the passage of transport.

The purpose of the invention is to improve performance by allowing the door to be locked in the open position.

FIG. 1 and 2 the door is respectively provided in the closed and open positions; on fig.Z - the device on dcH of a turn of a door, a longitudinal section; Fig. 4 is a graph of changes in the magnitudes of the effective moments applied to the door leaf.

The device consists of two levers 20 P fully open position

1 and 2, pivot axis 3, door leaves 4o. The levers 1 and 2 are fixed on the axis two- and on ball bearings 5 and 6. The pivoting of the door fixedly with an interline spike 7 is attached to the crossbar 8 with two 25 drivers. , 9 and 10. To the levers with the help of: (and earrings 11 and 12, having a sickle shape, there are attached return springs 13 and 14, with other ends reinforced on the bottom of the door 15, on whose Q there are fixed stops 16 and 17. Axis 3 The turn is supported by a ball bearing 18 on the base of the door 15.

In the closed position of the door, the levers 1 and 2 by the springs 13 and 14, acting through the earrings 11 and 12, are pressed against the leads 9 and 10. The outer ends of the levers 1 and 2 approach the stops 16 and 17 so that between the levers and the stops there remains a small technological a gap that does not affect the operation of the device. Its presence causes a backlash of the door, within which no moment is applied to the door leaf 4. On the characteristic of the operating moments (Fig. 4), this section is between the angles of rotation tf and tp ..

When the door is rotated (top view counterclockwise), starting from the angle if, the leash 10 rests on the lever 2 and turns it behind itself. The spring 14 through the shackle 12 applies to the door leaf 4 a closing moment defined by its prestressing force, folding with an ever-increasing tensile force and arm L, (, cr of the acting force. Na40

(emphasis on the diagram not shown). In this position, the angle between the axis of the lever pressed against the door leash and the direction of the spring action is negative (indicated in FIG. 2), this fully open position of the door leaf can last for as long as desired. This position is used for the passage of pedestrian traffic and transport passage or to ventilate the room in summertime. To return the door to the closed position, it is necessary to attach closing moments at the angles of rotation of the door sash from cpg to cj to the sash 4). At the same time, turning 10 through the stud 12 will turn the gears chag 2 to the angle Cf. Continuing movement, the flap 4 with a small knock defined by the gap between the guide and the lever 2, the lever 2 comes into contact with the leash 10 and the return spindle 14 will apply an increasing moment to the flap 4. C. This angle of rotation can be released unit 4, which will return to its original closed state under the action of gate spring 14.

The operation of the device when opening the door leaf in a clockwise direction, proceeds similarly. In this case, the lever 2 rests on the support 15 and the lever 1 interacts with the flap 4 through the leash 9.

The arrangement of levers 1 and 2 in different construction planes (as shown in Fig. 3) allows the interaction of the leads 9 and 10 with the levers 1 and 2 with the studs 11 to be cut.

the rank from this angle is opened, the lever 1 rests on the anvil 16 and the reinforcement from the age spring 13 closes through the base of the door 15.

As the door is opened, the shoulder of the acting force decreases, and the earring 12 comes close to the driver 10. In the position of the angle cp, the closing moment of the door is zero. Upon further opening of the door mark the shoulder. the acting force changes to negative and the moment applied to the door leaf becomes open. Starting from this angle of rotation, the leash of the door 10 moves away from the lever 2 and rests B on the stud 12, turning, if there is no opposing force from the pedestrian, the shutter 4 of the door goes to the fully open position

(emphasis on the diagram not shown). In this position, the angle between the axis of the lever pressed against the door lead and the direction of action of the spring is negative (indicated in Fig. 2) this fully open position of the door leaf can last as long as desired. This position is used for the passage of pedestrian flows and the passage of vehicles or to ventilate the room in summertime. To return the door to the closed position, a closing moment should be applied to the door leaf 4 at the angle of rotation of the leaf and the door from cpg to cj). In this case, the lead 10 through the stud 12 will turn the lever 2 to the angle Cf. Continuing the movement, the flap 4 with a small knock, defined by the gap between the guide 10 and the lever 2, the lever 2 will come into contact with the lead 10 and the return spring 14 will apply an increasing moment to the flap 4. C. This angle of rotation can release the flap 4, which will return to its original closed state under the action of the return spring 14.

The operation of the device when the door is opened in a clockwise direction is similar. In this case, the lever 2 abuts against the stop 15 and the lever 1 interacts with the flap 4 through the lead 9.

The arrangement of the levers 1 and 2 in different construction planes (as shown in FIG. 3) makes it possible to realize the interaction of the leads 9 and 10 with the levers 1 and 2 with the lugs 11 and
