Known Flap turnstile according to the utility model patent RU 152783 U1 containing a three-section housing, which houses an electric motor, an electromagnetic clutch, a shaft with a flap, a control unit, passage sensors, an anti-panic unit.

The disadvantages of turnstiles under the patents RU 56690 U1 and RU 152783 U1 are their complexity, as well as significant dimensions and weight. Availability of flexible transmission.

Known automatic wicket gate according to the patent for invention RU 2 530359 C1, containing a fixed stand with bearing assemblies, a sash shaft mounted for rotation in bearing assemblies, a sash connected to the shaft, an electric drive, a fluid coupling installed between the electric drive and the shaft, a sash positioning mechanism, including a rocker arm mounted with the ability to swing on an axis perpendicular to the shaft axis, a spring with a tensioner and a spring-loaded pusher.

The disadvantages of the device under the patent RU 2 530 359 C1 are:

- limitation of the turnstile leaf positioning modes due to the design of the leaf positioning mechanism;

- the presence of a sash positioning mechanism, which is functionally not connected with the electric drive;

In accordance with the utility model, the term lower shaft is understood to mean an element that transfers torque from the gearbox shaft to the load, and provides the connection of the gearbox shaft with the compensation coupling. Depending on the design of the gearbox, a sleeve or other connecting element can be used instead of the lower shaft.

In accordance with the utility model, the term turnstile swing flap design also means its part, or an element that is not a part of the turnstile flap structure, but protrudes as an intermediate link, providing torque transmission to the turnstile flap from the turnstile swing flap drive unit.
