Date Jun. 19, 1997A self-opening and self-closing device enabling entry into a controlled access area includes a gate with two laterally retractable panels that may be opened by inserting a ticket or access card into a control mechanism. Each of the panels is controlled by a respective motor operated by the control mechanism. Each panel is secured to at least two runner members that are each operated by a roller secured to a link arm. The link arms are rotationally interconnected and rotated by the respective motor. Simultaneous rotation of the arms in opposite directions moves the two panels together (or apart) and thus closes (or opens) the entry device by moving each panel into a position in which it is locked by the respective arm in the horizontal position.

Description

Automatic opening entry device for controlled area

Technical area

The present invention relates to automatic devices allowing entry into controlled or restricted access areas such as public transport networks, and relates in particular to an entry device in such areas with automatic opening and closing.

State of the art

The common technique for controlling the entry of users into a public transport network such as the metro or the RER is to install entry devices whose opening is triggered by the introduction by the user of a access ticket, ticket or access card, in a control mechanism.

There are two types of current input devices. The first type is a turnstile with three branches whose rotation of 120 * allowing the passage of a single individual is allowed by the introduction of the ticket in the control mechanism. Such a device has the major drawback that it can be easily stepped over by the user who wants to defraud.

To overcome this drawback, a second type of input device has been installed for user control, either alone or in combination with the three-branch turnstile. It is a single door or two leaves, quite high, whose automatic opening, triggered by the introduction of the ticket in the control mechanism, is controlled by an electric or pneumatic system. Such devices have a number of drawbacks. First of all, current control systems require a relatively long time to execute their cycle and trigger the opening (approximately 0.5 to 0.7 s) and therefore require placing the ticket control mechanism access at a certain distance from the automatic door, which reduces the flow rate. Once triggered, the opening is brutal. Consequently, the system is noisy and subjected to vibrations, mainly at the end of opening, which reduce its reliability. In addition, a large power is required which makes the system expensive. Finally, the door passing from the closed position to the open position, being in front of a closed door can cause a feeling of confinement very unpleasant for the user.

The system described in US Pat. No. 1,643,454 relates to a garage door actuated by a crank driven by a motor. A roller secured to the crank rolls in a slide secured to the door, transforming the rotational movement of the crank into a translation of the door. Thus, a half-turn of the crank makes it possible to pass from the open position to the closed position with blocking thanks to the fact that the crank is stopped in a position slightly below the horizontal. This system which can be used with profit for the automatic closing and opening of gates, however has the disadvantage that the drive as well as the locking of the door by a single crank obliges to have a heavy door and / or a guide on the ground of the rail type or a long embedding because the force of opening or closing during accelerations and decelerations, and especially the force of break-in at the opening applied elsewhere than in alignment with the connecting rod creates a torque on the guide which is important and risks damaging the mechanism. In addition, such a system does not provide 1 automatic and rapid opening of the passage in case of accidental power failure.

Disclosure of the invention:

This is why the object of the invention is to provide an automatic opening and closing input device which overcomes the drawbacks mentioned above. This object is achieved thanks to the entry device, object of the invention, which is of the type comprising a gate with two side-erasing leaves, each leaf being integral with at least two slide elements each actuated by a roller integral with '' a crank, the cranks being interconnected in their rotation controlled by a motor associated with the gate and whose start-up is triggered by a mechanism for controlling an access ticket introduced by the user, the simultaneous rotation of the cranks in an opposite direction tending to separate (or bring together) the two leaves and therefore cause the opening (or closing) of the input device.

According to a characteristic of the invention, a cut-off clutch located between the motor and the shaft of one of the cranks makes it possible to separate the latter so that a return mechanism integrated in the rotary transmission of the cranks comes into play. action to allow automatic opening of each leaf.

According to another characteristic of the invention, when the input device is in the standby situation, each crank is in a middle position between the closed position of the input device and its open position so that the input device is half open, which avoids the feeling of confinement in the user.

Brief description of the drawings:

The objects, objects and characteristics of the invention will appear more clearly on reading the following description made with reference to the drawings in which: FIG. 1 represents the input device according to a preferred embodiment of the invention, in its standby position, FIG. 2 represents the same input device in its open position, FIG. 3 represents the same input device in its closed position, and Figure 4 is a schematic representation of the control system of the input device according to the invention.

Detailed description of the drawings; According to a preferred embodiment, the input device according to the invention shown diagrammatically in FIGS. 1, 2 and 3, is composed of a gate with two leaves with lateral erasure 10 and 12. Each leaf comprises at least two elements - slides, the rollers associated with each of the elements and rollers for the translational movement of the leaf. Thus, the left leaf 10 comprises a slide element 16, its roller 30 and a roller 14 in the upper part, and a slide element 20, its roller 36 and a roller 18 in the lower part. In the same way, the right leaf 12 comprises a slide element 24, its roller 42 and a roller 22 in the upper part, and a slide element 28, its roller 48 and a roller 26 in the lower part.

Inside each slide element, that is to say between the two parallel walls of the element forming a slide, a roller of cylindrical shape is in free rotation around an axis being at the end of a crank the other end of which is integral with a drive shaft capable of causing the crank to rotate. Thus, in the slide element 16 is the roller 30 secured to the crank 32 driven in rotation by the shaft 34. In the slide element 20 is the roller 36 secured to the crank 38 driven in rotation by the 'shaft 40. In the slide member 24 is the roller 42 secured to the crank 44 rotated by the shaft 46. Finally, in the slide member 28 is the roller 48 secured to the crank 50 driven in rotation by the shaft 52.

The input device according to the present invention shown diagrammatically in FIG. 1 is in the standby position, that is to say that it is in the rest position, in waiting for the introduction of a ticket in a control mechanism.

In the waiting situation of FIG. 1, the cranks 32, 38, 44 and 50 are in the vertical position and the rollers 30, 36, 42 and 48 are at the highest in the elements 16, 20, 24 and 28. In done, the input device is in an intermediate position that is to say that it is neither open nor closed. Thus, in the embodiment of Figure 1, the space 11 between the two leaves is 30 cm. This is to not give the user who presents himself that he is locked up, which could be the case if the two leaves were close to each other.

When a user presents himself and introduces a ticket into a control mechanism, two solutions can occur. In Figure 1, the arrows on either side of the rollers also illustrate these two possibilities. If the entry ticket is valid, the shafts 34, 40, 46 and 52 are rotated counterclockwise (left arrows) for shafts 34 and 40, and clockwise a watch (arrows on the right) for shafts 46 and 52. The two leaves move away from each other to lead to the opening of the input device as illustrated in FIG. 2 During this maneuver, the rollers 30, 36, 42 and 48 are lowered to their lowest position in their respective slide elements 16, 20, 24 and 28, while driving the slide elements 16 and 20 to the left and the slide elements 24 and 28 to the right.

During the opening movement, each leaf slides in its own plane, being guided and supported by the rollers 14, 18 (for leaf 10) and 22, 26 (for leaf 12). The rollers are guided in movement by guides having guide walls. Thus, the rollers 14 and 18 roll respectively in the guides 54 and 56 secured to a box 55, and the rollers 22 and 26 roll respectively in the guides 58 and 60 secured to a box 57. It should be noted that other mechanisms could be used for sliding leaves such as ball or skid mechanisms. For example, the leaves could slide in grooves made in the ground and / or ball bearings could be fixed under the leaves to facilitate this sliding.

In the open position of the input device as illustrated in Figure 2, and with cranks of length equal to 10 cm, the distance t2 between the two leaves is approximately 50 cm, allowing the user to pass regardless of size.

The second case occurs when the user has introduced an invalid ticket into the control mechanism. In this case, the input device goes into the closed position shown in Figure 3. To do this, the shafts 34, 40, 46 and 52 are rotated, clockwise for the shafts 34 and 40 and counterclockwise for shafts 46 and 52. During this maneuver, the rollers 30, 36, 42 and 48 are lowered to their lowest position while driving the slide elements 16, 20 on the one hand and 24, 28 on the other hand to get closer, and therefore also to bring the two leaves closer to each other. In this position, the spacing / 3 between the two leaves is reduced to 10 cm, which does not allow an individual to pass. It should be noted that the distances il, il, 13 between the leaves in the respective positions of waiting, opening and closing of the input device are a function of the extent of the rotation of the cranks driven by the shafts. drive and their length. If, in the embodiment shown in FIGS. 1, 2 and 3, the length of the cranks is increased by 5 cm, the distance 11 from the standby position remains unchanged at 30 cm, but the distance il from position d the opening goes to 60 cm while 13 (closed position) goes to 0 (the leaves touch each other).

On the other hand, these spacings can be varied by playing on the angular deviation of the cranks. While maintaining the vertical cranks in the standby position, in the closed position of the leaves 10 and 12, the cranks 32, 38, 44 and 50 must be at least in the horizontal position or even slightly below the horizontal so as to ensure a locking preventing opening of the leaves by break-in.

Furthermore, it is possible to use a different motor speed at opening and closing so as to have opening speed of the leaves different from their closing speed.

The embodiment illustrated in FIGS. 1, 2 and 3, in which, in the open or closed position, the cranks are horizontal, is preferably used. Indeed, in this device, a rotational movement of the drive shafts is transformed into a sinusoidal linear movement of the slide elements. Consequently, when the crank reaches a horizontal position at the end of the opening or closing movement, the speed communicated to the slide element and therefore to the leaf is equal to zero. This zero speed prevents the gate from suddenly stopping at the end of the travel of the previous devices.

FIG. 4 schematically illustrates the control system for the rollers 42 and 48. This system includes a ticket control mechanism 62 which controls the operation of a motor 64. The latter controls the rotation of the shaft 46 by means of 'a current draw clutch 66. The drive shaft 46 is connected to the shaft 52 by means of a belt 68. Likewise, the movement of the shaft 34 is communicated to the shaft 40 by means of a belt 70 (see Figures 1, 2 and 3). It should be noted that the belts could be replaced by any other movement transmission system such as a chain or a cable or any other mechanism, in particular a link mechanism with preferably a rotation angle of the link less than 180 *.

In a preferred embodiment, each of the two belts 68 or 70 is provided with a counterweight 72 or 74 respectively, which is in the low position when the door is open (see Figure 2) and in the high position when the door is closed (see Figure 3). When there is a power failure, the current draw clutch 66 is no longer supplied, the latter is then in the disengaged position. The shafts are therefore no longer controlled and the two counterweights descend in their low position causing the movement of the belt which causes the leaf drive shafts to undergo rotation in order to bring the latter into the position illustrated in FIG. 3, c ' ie in the open position.

Although of simple shape in the embodiment illustrated in the figures, the roller 30, 36, 42, 48 can be more elongated or in two parts on either side of the crank, without this going beyond the framework of the 'invention.

According to another embodiment, the counterweight can be replaced by any other return mechanism and in particular a spring, one end of which is fixed at the same point as the counterweight 72 or 74, the other end being fixed in the lower part of the boxes 55 and 57 in order to activate the belts 68 and 70 in the event of a power failure to allow opening. According to another embodiment, the counterweight can be replaced by one or more torsion springs mounted on the shafts 34, 40, 46 and 52 secured, on the one hand, to the respective cranks, on the other hand, boxes 55 and 57. In the event of a power failure, their pretensioning in the closed position of the leaves will act on the cranks for rotation of the latter up to the open position of the leaves. Another advantage lies in the short opening or closing travel of the device thanks to the intermediate waiting position. This opening maneuver much faster than that of existing systems (approximately 0.2 s) also has the advantage of being able to place the ticket control mechanism or any other very authorization means. As we have seen previously, the structure of the device imposes a zero speed of the leaves at the end of the stroke. It is therefore not necessary to request an acceleration or deceleration effort from the engine. The motor torque required is therefore relatively low and there is therefore no need for a force limiter for the safety of the user during closing in the event of a fault. On the other hand, the combination which has just been described, comprising at least two cranks, has the particularity of guaranteeing an absolute blocking in the closed position and therefore a good aptitude for anti-fraud control insofar as the efforts of attempt to opening are not transmitted to the guides or to the drive mechanism.
