Description

The invention relates to checkpoint devices.

A movable fence is known as a turnstile containing a column fixed on the base with the possibility of rotation and carrying pin elements (see RF application No. 2006109540 of 10.10.2007).

A disadvantage of the known device is the low functionality, because the turnstile design does not allow to exclude unauthorized access and has low reliability due to the use of the rotation mechanism of the rod elements.

The technical result to which the invention is directed is to eliminate the aforementioned drawback and to reduce the area occupied by the movable fence.

This result is achieved by the fact that the movable guard comprises a supporting element fixed on the base with a possibility of rotation, on which at least one passage stop and a synchronizing mechanism consisting of one gear fixedly mounted relative to the base, gears fixedly fixed are rotatably fixed relative to the respective passage limiters, and gears mounted on the supporting element between the specified one gear and the corresponding gear, motionless th relative to the passage stop.

The guard may be provided with a rotation lock of the carrier, and the synchronizing mechanism may be configured to rotate the carrier one-way and / or to switch the direction of rotation of the carrier.

The passage limiter, depending on the specific installation location of the movable fence, is made in the form of a door or is formed by rod elements.

The invention is illustrated by drawings.

1 schematically shows a synchronization mechanism when using one passage limiter; figure 2 is the same when using two passage stops; figure 3 is a schematic illustration of a turnstile with one door; figure 4 is a schematic illustration of a turnstile with two doors; figure 5 - the position of one limiter passage during the operation of the movable fence; figure 6 - position of the two limiters of the passage in the process of operation of the movable fence; in Fig.7 - the position of the three passage limiters during operation of the movable fence; on Fig - stages of the movable fence with a shortened limiter passage.

The movable fence comprises a beam 2 (supporting element) that is mounted on a fixed supporting structure 1 (base) with a possibility of rotation, on which at least one door 3 (passage limiter) and a synchronization mechanism consisting of one gear 4 are fixed with rotation, motionlessly fixed relative to the motionless supporting structure, gears 5, motionlessly fixed relative to respective doors, and gears 6, mounted on a beam between said one gear 4 and the corresponding gear 5, fixed relative to the door.

A mechanism can be located on the beam 2 (not shown in the drawings), providing one-sided rotation of the beam, switching the direction of rotation of the beam and blocking its rotation. When the door moves in a circle, the center of which is the place of hinging the beam on the supporting structure, the door rotates in the same direction in which the beam rotates, with a coefficient specified by the synchronizing mechanism (4, 5, 6). The gear ratio of gears 4 and 5 is equal to two.

The supporting structure 1 is mounted on racks 7 and 8 of the enclosing elements. The synchronizing mechanism is closed from below by a central protective casing 9, mounted on a supporting structure 1, and an external protective casing 10, based on racks of enclosing elements.

Moving along a given beam of a circular trajectory and simultaneously turning relative to its attachment to the beam (Fig. 5), the door changes its position so that between the fence and the door there is constantly formed enough space for one person to pass in a given direction, and the entrance and exit spaces are alternately closed by a door. The gaps between the door and the fence at any time the door is too small for visitors to enter in the opposite direction.

The width of the door determines the free space between the door and the fence in which the visitor is located. The dimensions of the door 3 and the beam 2 determine the design purpose: organization of one-way traffic with the control of each visitor or organization of one-way traffic with increased throughput. In the latter case, the dimensions of the structure are increased so that there is enough free space for several visitors to pass simultaneously, and the gaps between the door and the fence do not allow visitors to enter in the opposite direction.

A two-door turnstile is a modification of a one-door turnstile device. A distinctive feature of such a device is a more straightforward path along which the visitor passes through the turnstile. Doors are the same size and are at an angle of 90 degrees to each other at any time. The operation scheme of the device with two doors and the device with one door are not fundamentally different.

The synchronizing mechanism consists of gears 5, fixedly mounted relative to the corresponding doors 3, gear 4, fixedly mounted relative to the supporting structure 1, and gear 6, mounted on the beam 2. The gear ratio of gear 4 to gear 5 is two. The synchronizing mechanism from below is also closed by casings 9 and 10.

Both doors connected by a beam and a synchronizing mechanism rotate along a circular path in a horizontal plane defined by the places of fastening the doors to the beam, and at the same time rotate relative to the place of their fastening to the beam, while the synchronizing mechanism ensures the doors are perpendicular to each other at any time. During the movement of the doors, a space is formed sufficient for one person to pass in a given direction, and the entrance and exit spaces are alternately closed by the doors. The gaps between the doors and the guard at any time the doors are moving are small and prevent visitors from entering in the opposite direction. The width, thickness and shape of the doors are set so that the doors do not intersect in space during rotation.

The width of the doors determines the free space between the doors and the fence in which the visitor is located. The dimensions of the doors 3, fences and beams 2 are selected so that at any moment the doors move along a given path, the visitor has enough free space between the doors and the fencing. The width of the doors is selected depending on the purpose of the design: the organization of one-way traffic with the control of each visitor or the organization of one-way traffic with increased throughput. In the latter case, the dimensions are chosen so that the space between the doors and the fence is sufficient for the simultaneous passage of several visitors. The gap, which is formed between the doors in the stationary state of the device, is closed by an additional element of the fence.

The device with three doors (Fig.7) is a modification of the device with one door and works on the same principle. Doors are located at an angle of 60 degrees. The gap formed between the doors is closed by an additional fence.

Modifications of the device, made with four or more doors, also achieve the stated result, however, an increase in the number of doors leads to an increase in the dimensions of the device and some operational inconveniences.

The use of shortened doors can reduce the consumption of materials necessary for the manufacture of the device. The movable mechanisms in such a device can be located above and / or below the device, and the passage stops are connected to the rotating beam by additional rods.
