Description

The present invention relates to the construction, namely, to the designs of gates used to pass people at the checkpoints for various purposes. In particular, double-sided wickets with doors opening on both sides (entrance and exit) are considered. After a person passes through such a gate in any direction, the mechanism for returning and positioning the gate leaf should return the leaf to its original position “passage closed”.

The known mechanism of the "double hinge" used to suspend a door turning on both sides (at the entrance and exit). One spring-loaded hinge (left or right) is attached to the door frame, while another similar hinge (respectively, right or left) is attached to the first hinge, which provides two-way opening and closing of the door (see U.S. Patent 2,293,042, publ. 18.08. 1942).

The disadvantage of this design is that when the door is opened left and right, it rotates around different axes, which makes it impossible to apply it to gates with a fixed axis of rotation of the leaf.

There is a known mechanism for closing a door (wicket, shutter), in which the weight of the door is used: when passing through the door, it rises due to the special curved profile of the split support cam, one half of which is stationary, and the other is fixed on a rotary shaft with a wing. After a person passes under the influence of the weight of the door, the halves of the cam slide relative to each other while turning the door to its original closed state (see patent DE 3818178 (A1), CL IPC: E05F 1/06; publ. 07.12.1989).

The disadvantage of this mechanism is the difficulty of manufacturing a curved profiled cam. In addition, when the door is rotated, it moves in a vertical plane (up when opening and down when closing), which makes this mechanism unacceptable in most gate and door designs.

The closest analogue to the proposed invention is a “Turnstile”, containing a fixed base, a shaft mounted on it with the possibility of rotation of the cross, made in the form of a conical disk with three guards, the mechanism of rotation of the cross in the form of a cam mechanism with a spring-loaded pusher and a locking mechanism, the fixed base along the central axis is equipped with a shaft rotating in boss bearings, rigidly mounted from the bottom of the base, and the cam mechanism is made in the form of a cam with three an oval oval lateral surface, the upper part of which is equipped with teeth alternating with three symmetrically located depressions parallel to the vertical axis of the cam, while a rigidly mounted disk with perforation is mounted on top of the cam and three rollers are located below, in addition, the rotation mechanism of the crosspiece is equipped with two electromagnets with spring-loaded anchors connected by levers with two dogs, cutouts of which interact with cam rollers, as well as a pusher with a spring-loaded rod and a wedge-shaped bar of the first form, with a damper and a lever with a roller coming in contact with the oval lateral surface of the cam, in turn, the locking mechanism is made in the form of a spring-loaded ratchet located on an axis from above the fixed base and engaged with the cam teeth, in addition, the turnstile is equipped with a controller containing a board with sensors that respond to the rotation of a perforated disk (see Utility Model Patent RU 24499, cl. IPC: E06B 11/08, publ. 08/10/2002).

The disadvantage of the rotation mechanism of the crosspiece of this turnstile is that for positioning the cross when the blocking rods approach the initial position, a cam mechanism with a spring-loaded pusher of the progressive type of movement located perpendicular to the axis of the crosspiece shaft is used. The cam mechanism with a spring-loaded pusher of progressive type has large dimensions, so it can only be used in devices that allow significant housing dimensions in the horizontal plane (for example, in the curbstones, the length of which in the horizontal direction reaches one meter). However, such a design is unacceptable in products such as wickets, the case of which should have small horizontal dimensions, but are very elongated vertically. For wickets, the cam mechanism should be as horizontal as possible. This can be done painlessly by increasing the size of the mechanism vertically due to the practical unlimited space in the gate housing in this direction.

The technical result of the invention is to create a compact in the horizontal plane and reliable design of the mechanism for returning and positioning the leaf of the double-sided gate (hereinafter referred to as the return mechanism).

The achievement of the specified technical result is ensured due to the fact that the gate contains a stationary rack with bearing assemblies, a shaft mounted rotatably in the bearing assemblies, a shutter connected to the shaft, a shutter return and positioning mechanism, a shutter smooth adjustment device, a shutter fixing mechanism, an angle sensor turning, electronic control unit, light indication and remote control.

In accordance with the invention, the mechanism for returning and positioning the sash is made in the form of a cam mounted on the wicket shaft rigidly and coaxially with the shaft, as well as in the form of a rocker mounted to swing on an axis perpendicular to the axis of the shaft and the plane of the sash in its initial position.

The cam is equipped with two stops mounted for rotation on two axes, which are rigidly fixed in the cam and are parallel to the axis of the shaft. The stops interact with a pusher mounted with the possibility of free rotation on an axis rigidly fixed to the end of the rocker arm opposite to the swing axis, pressed against the stops by a return spring.

In addition, the stops are made in the form of any body of revolution (roller, rolling bearing, etc.).

In addition, the rocker pusher is made in the form of a tube.

In addition, the return spring is made with an adjustable tension force.

In addition, the stops are installed so that when the shaft with the leaf is rotated to any angle within ± 90 ° from the initial position, torque appears to return the leaf to its original position.

Thanks to this arrangement of elements, the design of the mechanism for returning and positioning the sash, and accordingly the gate itself, was made more compact and reliable, and as a result of installing the stops in this way, it is possible to create a torque that returns the sash to its original position when the gate shaft is turned at any angle in ± 90 ° from the starting position.

The mechanism for returning and positioning the gate leaf is illustrated by the drawings:

Figure 1 - presents a General view of the gate with a return mechanism in the initial position of the blocking sash;

Figure 2 is a view of the bottom return mechanism at the initial position of the blocking sash;

Figure 3 - presents a General view of the gate in the open position with the return mechanism when the rotation of the blocking sash 90 ° to the left;

Figure 4 is a view of the bottom return mechanism in the extreme left-open position of the blocking wing;

Figure 5 - presents a General view of the gate in the open position with the return mechanism when the rotation of the blocking sash 90 ° to the right;

Figure 6 is a view of the bottom return mechanism in the extreme open to the right position of the blocking sash.

The mechanism of return and two-way positioning of the gate leaf contains a cam 1 with two axles 2 rigidly fixed thereon, on which rotating stops 3 are mounted; rocker 4; a spring 5 with a tensioner 6. The cam 1 is rigidly and coaxially mounted on the gate shaft 7, for example, using a pin 8. The shaft 7 is mounted for rotation in the bearing assemblies 9 located in the gate housing 10. A blocking sash 11 is rigidly fixed to the shaft 7.

The beam 4 is mounted with the possibility of swinging on the axis 12, rigidly fixed in the housing 10 of the gate and located perpendicular to the axis of the shaft 7 and the plane of the sash in its original position. At the opposite end of the beam, the axis 13 is rigidly fixed parallel to the axis 12, on which the pusher 14, made in the form of a tube, is mounted with the possibility of free rotation.

When the shaft 7 is rotated with the shutter 11 in the bearing units 9, the cam 1 is mounted rigidly mounted on it. In this case, the stops 3 mounted on the axles 2 of the cam 1 act on the rocker pusher 14, forcing the rocker 4 to rotate about axis 12. When the rocker 4 is rotated 4 spring 5 is stretched, thereby creating a moment that counteracts the opening of the sash.

After a person passes through the gate, the tension spring 5, compressing, returns the rocker 4 to its original position, while the pusher 14 of the rocker 4 presses on one of the stops 3, creating a moment that returns the gate 11 of the gate to its original position. In the initial position of the sash 11, the “passage is closed”, the pusher 14 of the rocker arm 4 immediately presses on two stops 3, thereby stopping and positioning the sash 11 in the initial position (see FIGS. 1 and 2).

An important design feature is the presence of a freely rotating pusher 14, since when the rocker is swinging, the axis 13 moves vertically; the rotating pusher 14 avoids sliding friction of the pusher against the stops and uses rolling friction, which contributes to the long-term operation of the mechanism.

To adjust the speed of return of the sash 11 to its original position introduced the tensioner 6 of the spring 5.

To smoothly stop the gate leaf in the initial position, a device for smoothly closing the leaf is used (not shown in the figures).
