Description

TECHNICAL FIELD The present invention relates to a gate for controlling access to escalators or moving sidewalks or the like. PRIOR ART Installations of the escalator type or moving walkways or similar have been, from the 10 years 1970, massively installed in public places such as department stores or subways, to streamline the movement of individuals in these public places. These installations operate continuously all day long and their constituent elements are in great demand, especially during peak hours. Given these heavy demands, said facilities are frequently stopped for maintenance reasons or following untimely stops related in particular to untimely support on the emergency stop buttons. During these periods of stops, it is necessary to prohibit public access to these facilities to allow easy intervention and to avoid any risk of accident including falls during restart. Currently, in order to solve this problem, before the start of any operation, the intervention company is obliged to place a person at each end of the installation, on the one hand, to wait and verify that the latter is empty and, secondly, to then prohibit access by setting up removable barrier in front of each end. However, this intervention is cumbersome and heavy because it requires the presence of at least two people equipped with radio transceivers BGA001-EN-19_TEXTE DEPOSE_RG-GE - 2 - Radiotelephone. In addition, the barriers in place are typically heavy and cumbersome and make difficult an emergency passage.

DISCLOSURE OF THE INVENTION The object of the present invention is therefore to overcome the aforementioned drawbacks and to provide a manual or automatic gate and able to be controlled remotely to control access to facilities such as escalators, moving walkways or similar without preventing the exit of people between the two ends of said facilities and while allowing an emergency passage ensuring the safety of users, said gate is also robust, simple to implement and reduced space . According to the invention, it is therefore proposed a gate to control the access of at least one end of a escalator or a moving walkway or similar remarkable in that it comprises at least: - a pole fixed near said end; a barrier fixed on a movable element disposed at least partly inside said post and able to pivot about an axis so that the barrier moves between an open position which releases the passage to allow access to the end of the escalator and a "closed" position blocking the passage to prevent access to said end, - a drive motor in rotation of the assembly 30 movable element - barrier, - a coupling member of the clutch type coupled to the motor and adapted to cooperate with the movable member to drive it in rotation, - mechanical limit stops limiting the stroke of BGA001-FR-19_TEXTE DEPOSE_RG-GE - 3 - the mo element bile, and - an end-of-travel detection device. Advantageously, the coupling member comprises an arm adapted to cooperate with a yoke secured to the movable member. The movable element is preferably disposed inside a housing of the post delimited by at least one lower flange and an upper flange. Advantageously, the abutments are studs 10 screwed or welded to said lower flange, extending towards the movable element and able to come into contact with the yoke of the latter. According to a preferred embodiment, the end-of-stroke detection device comprises a slot in the upper flange, an axis fixed on the movable element and passing through said slot, and microcontacts fixed on the upper flange in the vicinity of each ends of the light. The microswitches are preferably of the end switch type. Advantageously, the "closed" position of the gate is retractable under the effect of an abnormal force to allow an emergency passage without risk for users. According to a preferred embodiment, the stops and the axis are "fusible" or retractable. The stops 18, slot 20 and pin 21 are advantageously positioned symmetrically with respect to an axis perpendicular to the longitudinal axis of the mechanical staircase 3. According to a preferred embodiment, the gate includes signaling and signaling equipment. control selected from the group consisting of light indicators, sound and light warning devices and BGA001-EN-19_TEXTE DEPOSE_RG-GE - 4 - means of manual control and / or remote opening and closing of the fence. BRIEF DESCRIPTION OF THE FIGURES Other advantages and features will become more apparent from the following description of an embodiment of a gate according to the invention with reference to the appended figures in which: FIG. 1 is a perspective view partial 10 of a gate according to the invention in the "closed" position installed at the bottom of a escalator; - Figure 2 is a front view of the gate of Figure 1 in the "closed" position; FIG. 3 is a vertical section of the gate of FIG. 2 along axis III-III 'of FIG. 6; FIG. 4 is a view of a first detail of FIG. 3; FIG. 5 is a view of a second detail of FIG. 3; Figure 6 is a horizontal section of the gate of Figure 2 along axis VI-VI 'of Figure 4; FIG. 7 is a horizontal section of the gate of FIG. 2 along the axis VII-VII 'of FIG. 5. Best way of carrying out the technical invention The gate installed on a horizontal ground in the vicinity will be described below. the lower end of an inclined escalator to move from one level to another in a building for example commercial type. It goes without saying that said gate may also be installed at the high end of said escalator, but also at the ends of a moving sidewalk or the like or on more or less inclined ground, the terms vertical and / or horizontal will be then to adapt to BGA001-FR-19_TEXTE DEPOSE_RG-GE - 5 - the inclination of said ground. Referring to Figure 1, the present invention relates to a gate 1 for controlling access to the lower end 2 of a escalator 3 and having a pole 4 fixed on the ground 5 near said end 2 and a barrier 6 fixed on a movable element 7 disposed at least partly inside said pole 4 and pivotable about a substantially vertical axis 8 so that the barrier 6 moves between an "open" position 10 disengaging the passage to allow access to the end 2 of the escalator 3 and a "closed" position blocking the passage to prevent access to said end 2. It is understood that the movable member 7 may 15 pivot about a substantially horizontal axis 8 without departing from the scope of the present invention. With reference to FIGS. 2 to 7, the movable element 7 of the gate 1 is of generally cylindrical shape, disposed inside a housing 9 of the column 4 and is driven in rotation by means of a motor 10, electrical preference, the housing 9 of the pole 4 being delimited by a peripheral wall 11 and two separating flanges subsequently named lower flange 12 and upper flange 13. For reasons of ease of electrical connection, the motor 10 is preferably integral with the In addition, for reasons of stability, the movable element 7 is integral with the upper flange 13 via a pivot 14 fixed on said upper flange 13. To limit the effort to avoid any risk of injury to a user when moving the barrier 6 and allow an emergency passage if necessary even when the barrier 6 is in the "closed" position, the BGA001-EN-19_TEXTE DEPOSE_RG-GE - 6 - portil 1 comprises a coupling member 15 of the disc clutch type coupled to the motor 10 and preferably having an arm 16 adapted to cooperate with a yoke 17 secured to the movable member 7 to drive the latter. The rotation of the movable element 7-barrier 6 assembly is mechanically limited by two stops 18 fixed to the lower flange 12, said stops 18 being advantageously studs screwed or welded to said lower flange 12 and extending towards the lower flange 12. movable element 7. These stops 18 are adapted to cooperate with the yoke 17 of the movable member 7 to limit the displacement of the latter. In addition, in order to control the motor 10 and control 15 in particular the start-up, the direction of rotation and the stop of the latter, the gate 1 comprises a limit-of-travel detection device 19 making it possible to detect whether the element assembly mobile 7 - barrier 6 is at one of the extreme positions of its displacement corresponding respectively to the "open" and "closed" positions of the barrier 6. Said end-of-travel detection device 19 comprises a light 20 formed in the upper flange 13, an axis 21 fixed to the movable element 7 and passing through said aperture 20 and microswitches 22, of the end switch type, fixed on the upper flange 13 in the vicinity of each of the ends of the light 20 and preferably above said upper flange 13. The microswitches 22 are preferably fixed on removable supports 23 immobilized in position by screws 24, said supports 23 allowing adjustment of the final position of the microswitches 22 with respect to the light 20. These microcontacts 22 allow, on the one hand, to stop the rotational movement of the motor 10 when BGA001-FR-19_TEXTE REMOVAL_RG-GE - 7 - movable element 7 - barrier 6 has arrived at one of its extreme positions and, secondly, automatically restart the rotational movement if the movable element 7 - barrier 6 is moved from one of its extreme positions. These microswitches 22 also serve to send information to the control station. Furthermore, for obvious security reasons, the "closed" position of the gate 1 is retractable under the effect of an abnormal force to allow an emergency passage without risks for users during a crowd movement by example. To do this, we can for example provide a barrier 6 adapted to bend or a pole 4 adapted to pivot about a substantially vertical axis, under the effect of an abnormal force. However, according to a preferred embodiment, the stops 18 and the axis 21 are retractable or "fusible" that is to say that they are sized to yield under the effect of an abnormal force. In addition, the gate 1 comprises signaling and control equipment such as, for example, light indicators 25 informing whether or not the access to the escalator 3 is in use, a sound and light device (not shown in the figures). ) triggering before any rotational movement of the barrier 6 or the means 26 for manual control and / or remote from the opening and closing of the barrier 6 (see Figure 2). The remote control means 26 will allow a single person to easily and simultaneously block both ends of the escalator 3.

Finally, in a preferred embodiment, the stops 18, light 20 and axis 21 are positioned symmetrically with respect to an axis perpendicular to the longitudinal axis of the escalator 3 so that the same door can be intended for left or right side of said BGA001-EN-19_TEXTE REMOVAL_RG-GE -8 - escalator 3. Similarly, the stops 18 are advantageously positioned so that the opening direction of the barrier 6 does not oppose the exit of a user who would be between the two ends of the escalator 3. Possibility of industrial application The gate 1 according to the invention applies more particularly to escalators or moving walkways or the like, but it can also be used to a completely different installation which it is desired to prohibit temporary access such as for example a corridor or a hall.

Finally, it goes without saying that the examples of gates 1 according to the invention which have just been described are only particular illustrations, in no way limiting the invention. BGA001-EN-19_TEXT DEPOSE_RG-GE
