Description

PIVOTING LEAF CONTROL DEVICE FOR ACCESS CONTROLLED PASSAGE

The present invention relates to a device for controlling pivoting leaves for passage with access control, comprising at least one leaf capable of pivoting between a position for releasing said passage and a position for closing this passage, reading means, detection and control of authorization of passage for users, and of pivoting control members of said leaf between the aforementioned positions, these members being subject to control of the aforementioned means.

In known devices of this kind, said reading means are in principle means for reading tickets which, in cooperation with detection and control means of passage automation, make it possible to release only the entry or the exit to authorized users. These devices have been specially designed for passenger toll systems, facilitating the flow during peak traffic and preventing access to unauthorized users. These pivoting leaf passages can operate in P.N.O. (Normally Open Passage, for very large flow) or in P.N.F. (Normally Closed Passage). They can also operate in a unidirectional direction (from the inlet to the outlet or vice versa) or in a bidirectional direction (from the inlet to the outlet and vice versa).

As for said control members, they most often include electric motors, which is costly in material and has the disadvantage of making the closure of the leaves rather abrupt, hence the need to provide specific means to ensure the safety of users. There are also difficulties when it is desired to make the closing of the leaves irreversible, that is to say preventing a closed leaf from being forcefully opened by a user. The object of the present invention is to solve these problems, and to avoid the drawbacks of the prior techniques.

To this end, a control device of the type mentioned at the beginning is, in accordance with the present invention, characterized in that said control members comprise at least one pneumatic cylinder supplied by means of a reserve of compressed air connected to a compressor, which is coupled to an electric motor. In principle there will be one pneumatic cylinder per leaf, but it is not excluded, at least in certain applications, that a single cylinder controls several leaves, in particular in the case of leaves which have to be operated in synchronism. This control mode will in any case allow a less brutal closing of the leaves, than a command carried out directly by electric motors, easily ensuring the safety of users, insofar as it will not be necessary to implement a very high pressure for the operation of the jacks.

Furthermore, the supply of pneumatic cylinders with compressed air has the advantage of being autonomous, since it does not require the use of compressed air from the network. The compressed air reserves will be automatically recharged by the compressors as soon as the pressure there falls below a determined threshold, and this for each of the passages controlled. The installation of the entire device will be simplified and will not require any modification of the infrastructure on the site: it will only be necessary to have an electric current supply on site, for the supply of the motors driving the compressors. According to an additional characteristic of the invention, the leaves are articulated around fluted vertical shafts secured to self-supporting trunks containing the aforementioned means and organs, each trunk constituting a separation between two contiguous controlled passages and each box incorporating a box containing a transmission mechanism between the rods of pneumatic cylinders and the corresponding leaf.

This will result in a particularly compact and economical construction. The use of fluted shafts for the articulation of the leaves will make them extractable from above, and therefore to disassemble them quickly, without further disassembly.

In the case of a device in which a controlled passage can be closed by at least one pair of opposite cooperating leaves, capable of pivoting simultaneously, in opposite directions, between said release and shutter positions, the invention may also be characterize in that the compressed air reserve of the trunk delimiting on one side the controlled passage concerned at the same time supplies the pneumatic cylinders controlling the one or said pairs of cooperating leaves of this passage.

According to yet another characteristic of the invention, it is provided that in each trunk, the casing of the transmission mechanism controlling the leaves of the passage located on one side of the trunk concerned is identical and mounted head to tail to the casing of the commanding transmission mechanism the leaves of the passage located on the other side of the same box. We can thus implement all identical mechanisms, whether installed upstream or downstream, to the right or left of the passage, and we can therefore easily standardize manufacturing.

According to another arrangement of the invention, the device could also be characterized in that a transmission mechanism between the rods of pneumatic cylinders and the corresponding leaf comprises a pivoting crank articulated on the one hand at a fixed point of the box, d on the other hand on the end of the rod of the corresponding pneumatic cylinder, this crank carrying at its free end, opposite to said fixed point, a roller or the like taken with an elongated light from a connecting rod wedged on the leaf leaf concerned, the arrangement being such that when the jack is in the position for which it ensures the closing of the leaf, the axis of said light is oriented perpendicular to the line which connects said fixed point to the axis of said roller.

In this way, it will be impossible for a user to forcibly open a closed leaf, because in the corresponding position of the mechanism, the roller will be locked in the elongated lumen of the connecting rod: it will not be able to rotate the crank on its point. fixed. The pivoting of the crank and consequently of the connecting rod and of the leaf can only be obtained by an action of the pneumatic cylinder.

An embodiment of the invention will now be described by way of non-limiting example with reference to the figures in the attached drawing in which:

- Figure 1 is an end view and in elevation of an access control passage according to the invention, showing the two boxes which delimit it as well as two pivoting leaves in the closed position;

- Figure 2 is a side elevational view of one of the boxes with the corresponding leaf in the open position;

- Figure 3 is a top view of passages according to that of Figure 1, schematically showing the compressed air supply of the pneumatic cylinders of the two pairs of leaves of each passage;

- Figure 4 is an end view and in elevation, schematically showing two neighboring access control passages;

- Figure 5 is a partial view on a larger scale of the framed part V of Figure 4, showing the head-to-tail position of two boxes containing the transmission mechanisms of the pneumatic cylinders controlling the leaves disposed on either side of the central safe;

- Figure 6 is a top view showing a transmission mechanism in a position corresponding to the closing of a leaf;

- Figure 7 is a top view of this mechanism in a position corresponding to one opening of the leaf; and

- Figure 8 is a diagram showing one supply of pneumatic cylinders with compressed air.

In the various figures, the leaves controlling the right part of a passage have been referenced ld, and the leaves controlling the left part have been referenced lg. Each passage 2, with a width of for example 0.5 m, controlled by one or more pairs of leaves ld, lg, is delimited by two self-supporting longitudinal trunks 3, for example made of steel, containing all of the reading means , detection and control of passage authorization for users, and pivoting control members of the leaves between their open and closed positions. These boxes are closed by covers made up of two articulated covers such as the one referenced at 4 in FIG. 4. The opening of the covers gives access to the contents of the boxes 3, which comprises:

- the ticket readers 5 (FIG. 3), the opto-electronic cells 6 with their reflectors 7, as well as the programmable controllers 8, receiving from these readers and cells the corresponding information I ₅ and I ₆ (see FIGS. 1 and 8) . These organs constitute what has been called above the means of reading, detection and control of authorization of the passage for the users. It should be noted that the management of passages, provided by the programmable controller 8, takes into account the passage authorizations issued by the ticket reader 5, the presence of a user as well as his direction of movement, in order to control ld, lg leaves,

- the pivoting control members comprising: the air compressors 9, which can be driven by electric motors (not shown) connected to the network and supplying intermediate air reserves 10, the pressure of which is controlled by pressure switches 11 capable of controlling the starting of the compressors 9 when the air pressure in the reserves 10 reaches a predetermined minimum threshold (see also FIGS. 1 and 8); and the cylinders 12d and 12g as well as their connection mechanisms to the corresponding leaves, ld and lg respectively.

In FIGS. 3 and 8, two pairs of jacks have been assumed per passage: upstream jacks 12d and 12g for controlling two upstream leaves, and jacks 12 ′ d and 12 ′ g for controlling downstream leaves. These cylinders are supplied with compressed air from the reserves 10, under the control of distributors 13, themselves controlled by the corresponding automaton 8 (see FIG. 8). It can be seen in FIG. 3 that one and the same reserve of compressed air 10 with the corresponding compressor 9, disposed in each of the safes 3, can supply, in synchronism, both the pneumatic cylinders controlling the leaves ld and lg and possibly the additional leaves the d and g of the passage 2 located to the left of the trunk 3 considered. In this way, all the safes 3, with the exception of the far left trunk 3g, may be identical, which simplifies manufacturing.

With regard now to the mechanisms more particularly, it should be noted that the leaves are mounted on fluted shafts 14d and 14g (see FIGS. 1 and 5) themselves pivotally mounted at their ends on lower self-aligning bearings. and higher, all referenced at 15. These leaves can be folded down in the closed position in housings 16 of the boxes 3.

The connection mechanism between each actuator rod 17 and the corresponding leaf, for example the right leaf ld in FIGS. 6 and 7, is produced in the following manner: the rod 17 is articulated by its free end on an axis 18 of a bent crank 19 suitable for pivoting at a fixed point 20 of a box 21 containing the mechanism and itself incorporated in the corresponding trunk 3. At its free end opposite the articulation point 20, the crank 19 carries a roller 22 engaged with an elongated lumen 23 of a connecting rod 24 wedged on the corresponding fluted shaft 14d of the leaf ld. The arrangement is such that in the retracted position of the jack rod, for which the latter ensures the closing of the leaf (FIG. 6) the X axis of the light 23 is perpendicular to the line Y which connects the fixed point 20 and the axis of the roller 22. We see that thanks to this arrangement any force exerted on the leaf ld in an attempt to cause its opening causes the bracing of the connecting rod 24 on the roller 22, without being able to pivot the crank 19. The leaf ld is therefore securely locked in this closed position, and can only be opened by the action of the jack 12d: the extraction of the rod 17 from the jack in fact makes the crank 19 pivot around the point 20 counterclockwise, the roller 22 slides in the light 23 and rotates the rod 24 clockwise, causing the leaf ld to open (Figure 7). Figures 6 and 7 show the mounting of the box 21 on the trunk 3 by means of soundproofing silent-blocks 25 and 26. It can also be seen in Figure 5 that the boxes 21 of the same trunk 3 can be identical (corner shape) and mounted head to tail, one controlling the leaf ld of a passage 2, the other the leaf lg of the neighboring passage 2, these boxes 21 being relative to each other in a relationship of axial symmetry. This further simplifies manufacturing by standardizing the boxes. It should be noted that in the event of a power cut, the leaves are automatically pressed into the housings 16 of the safes 3 to leave the passages free. To do this, distributors 13 are used with spring return, directing towards the jacks. air in reserve, which opens passages 2 without further control.

The use of pneumatic cylinders under low pressure allows in any case to obtain a very fast control of the leaves, in complete safety, the rotation of a leaf which can be carried out in approximately 1/2 second.
