Apparatus has two half doors (12,12') each designed to rotate around vertical axis (14,14') fixed to supports (10,10'). Opening of doors (12,12') is done by motors (26,26') whose actuation is triggered by sensing of ticket or access card placed in access control mechanism. Each door (12,12') is associated with drive mechanism having drive arm (20.20'), fixed to door (12,12') and designed to rotate around vertical axis; drive system (28,30; 28'30'), driven by motor and whose linkage with drive arm is done via roller (32.32') which is forced to follow guide (38,38') fixed to support (10,10') when door passes from closed position to open position and vice versa. Guide has notch (40,40') in which is lodged roller (32,32') when door (10,10') is in closed position which prevents opening of door (10,10') by exterior action other than action by motor.

Description

Technical area :

The present invention relates to devices automatic allowing access to controlled areas or regulated access such as transport networks in common, and particularly relates to an input device in an area controlled by two leaves to automatic opening.

State of the art:

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

The current access devices are of several kinds. The first type is a three-branch turnstile including a 120 ° rotation allowing the passage of a single individual is allowed by the introduction of the ticket in the control mechanism. Such a device presents the major drawback that it can be stepped over easily by the user who wants to defraud.

A second type of input device has two leaves rotatably mounted about a vertical axis and of which opening and closing are controlled by a motor electric driving the simultaneous rotation of each leaf around its axis. Unfortunately, this kind of device generally has a major drawback. In Indeed, when the two leaves are in the closed position, the leaf locking in the closed position is only due to the engine blocking at rest and is therefore little effective insofar as an average force exerted on the leaves will allow their opening. Furthermore, this force exercised against the engine blocked at a high risk damage the engine.

A device as described in the preamble of claim 1 is known from document FR-2760781.

Statement of the invention:

This is why the object of the invention is to provide a access device in a controlled area of the type comprising two motorized rotary leaves around an axis vertical and whose closure results in locking leaves automatically in the closed position without no possibility of opening.

The object of the invention is therefore an access device in a controlled opening and closing area automatic of the type comprising a gate with two leaves, each leaf being adapted to be rotated around a vertical axis fixed to the leaf support, the opening of it resulting from the setting in motion of a motor whose activation is triggered by the detection of a ticket or access card by a control mechanism access. Each leaf is associated with a mechanism drive comprising an integral drive arm leaf and moved in rotation around the vertical axis, drive means set in motion by the activation of the motor and whose articulation with the drive arm is done through a pebble forced to follow a guide secured to the support when the leaf passes from one closed position to an open position and conversely, the guide having a notch in which is housed the roller when the leaf is in closed position, preventing the opening of the leaf by an external action other than actuation of the motor.

Detailed description of the invention:

With reference to FIGS. 1A, 1B and 2A, 2B, the invention applies to access to a controlled area in which each access passage is made up of two supports symmetrical 10 (or 10 ') in the form of associated boxes each with a leaf 12 (or 12 ') arranged opposite. As illustrated in FIGS. 2A and 2B by the arrows in dotted, the leaf 12 (or 12 ') can make a rotation around an axis A to get into position closed or in the open position, this opening can be carried out when the leaf is in one or the other of the extreme positions of the angle of rotation. The rotation is achieved by means of a fixed 14 (or 14 ') bar at the top and bottom of the box 10 (or 10 ') and around which is articulated an upper bearing 16 (or 16 ') as well than a lower bearing 18 (or 18 '). It should be noted that the barre 14 (or 14 ') is not absolutely essential.

An arm 20 (or 20 ′) also articulated around axis A is made integral with the lower bearing 18 or (18 ') by an electromagnetic device 22 (or 22 ') acting on an axis 24 (or 24 '). The electromagnetic device is normally supplied so as to maintain the axis 24 or 24 ' in the high position crossing the arm 20 (or 20 ') and the bearing 18 (or 18 ') so that the arm 20 or (20') turns at the same time as the leaf 12 (or 12 '). In case of power failure, the electromagnetic device 22 (or 22 ') is no longer powered which brings back the axis 24 or (24 ') downwards thanks to a spring and separates the leaf 12 (or 12 ') of the arm 20 (or 20'). In these conditions, the leaves become completely free and can be manually moved to the open position. This provides security in the event of serious incidents such as a fire. It should be noted that the device electromagnetic 22 (or 22 ') could be replaced by any mechanical or other means ensuring the same function.

The rotation of the leaves to pass from the position of closing in the open position is controlled by a 26 (or 26 ') motor whose start-up is triggered by presentation or insertion of a card or ticket access. The motor actuates a crank 28 (or 28 ') in rotation around the B axis in one direction or the other. The crank 28 (or 28 ') is connected at its end to a connecting rod 30 (or 30 ') by a hinge C which can describe a circular path from point I to point J as illustrated in Figure 2A.

The rod 30 (or 30 ') has at its other end a roller 32 (or 32 ') articulated around an axis D. This roller is prisoner but in free rotation in an oblong housing 34. A pressing finger 36 'housed in the arm 20 (or 20') is permanently supported on the roller using a spring. This finger 36 'can fully enter the arm according to the position of the roller in the oblong housing 34.

The roller 32 (or 32 ') is in contact with the wall of a fixed guide 38 (or 38 ') in the shape of an arc of a circle and having a central oblong notch 40 (or 40 '). When the roller is resting on the arcuate area of circle thanks to the action of the pressing finger 36 ', that is to say between the end point H and the start of the notch, there is in abutment in the oblong housing 34 (or 34 ') of the arm 20 (or 20 '). Therefore, this connection behaves like a simple articulation around the axis D between the arm 20 (or 20 ') and the connecting rod 30 or (30'). When the leaf closes, the pressing finger 36 'facilitates the introduction of the roller 32 (or 32 ') in the notch 40 (or 40').

Therefore, the movement can be detailed from the next way between the closed position F and the open position O. At F, the arm 20 (or 20 ') occupies an extreme rear position and the C axis is in position I (see Figures 1B and 2B). The rod 30 (or 30 ') is then in extreme rear position and the roller 32 (or 32 ') is positioned at point G (see Figure 2B) in the bottom of notch 40 (or 40 '). In this configuration, the roller 32 (or 32 ') is immobilized in the notch. Arm 20 (or 20 ') is then unable to turn around axis A and therefore prevents the leaf from being opened by someone who would exert a rotation effort on the leaf to the extent that this effort results in a force exerted by the roller via the arm 20, perpendicular to the walls of the notch. The locking the leaves in the closed position is therefore perfect.

Then, when the motor 26 (or 26 ') is activated, the C axis goes from point I to point J as illustrated on the Figures 3A and 3B. First, the connecting rod 30 (or 30 ') is released from the notch 40 (or 40'), the roller 32 (or 32 ') then leaving point G and leaving the notch (Figure 3A). Then, the roller having come out of the notch, the crank 28 (or 28 ') rotated by the motor 26 (or 26 ') continuing to exert a lateral force by through the connecting rod 30 (or 30 '), the roller 32 (or 32 ') rests on the fixed guide 38 (or 38') (figure 3B). The progression of the roller of the oblong notch 40 (or 40 ') at point H (see Figure 2B) then allows the rotational drive of the arm 20 (or 20 ′) and therefore of the leaf 12 (or 12 '). During this movement, the axis D describes an arc of a circle up to point H, axis C describes an arc of circle to point J, the system behaving like a simple connecting rods because the axis D is then a simple joint.

At the end of the movement which has just been described, the leaf 12 (or 12 ') is in the open position (see Figure 2A) it should be noted that an external action on the leaf in order to move it from position opening to the closed position will have no effect because the axes B and D are perfectly aligned with joint C. Therefore, the device is locked in the open position. Unlocking does not can only be done by the reverse action of the driving motor the crank 28 (or 28 ') rotating and destroying the alignment of the joint C with the axes B and D.

According to an alternative embodiment shown in the Figure 4, the pressing finger 36 is replaced by a channel bearing 42 for the roller 32 located in the guide 38. The raceway 42 is symmetrical on either side of the notch 40, and has a point 44 in the part opposite the notch so as to favor the introduction of the roller 32 in the notch 40 when closing. This variant performs a function similar to the pressing finger 36 '.

As already mentioned, the leaves can open indifferently in one direction or the other of so as to allow the passage of users through a network of public transport, in particular the SNCF network, the metro or the RER. This is easily understood since where, when the leaves are in the closed position, the motor can be operated in one direction or in opposite direction so as to turn the crank 28 (or 28 ') in the clockwise or counterclockwise.

It should be noted that the two leaves are generally operated simultaneously, but it would be possible to operate only one of the two leaves.
