Definitions

  • the present invention relates to a device and a temporary closure assembly of a pedestrian crossing, such as a corridor, a gallery, etc.
  • the invention applies in particular to foot traffic networks, such as a network of underground corridors of a metro station or railway.
  • a network of underground corridors of a metro station or railway In such a network, several corridors intersect to allow pedestrians to move from one area of the network to another, according to their travel wishes, especially when these pedestrians make a connection between two subway lines serving network or when they join or come from one of the exits to the outside.
  • all these corridors are open to allow free movement of pedestrians in all possible directions.
  • the network of corridors may be intended only to be partially accessible to pedestrians: during maintenance interventions, during exceptional events outside the normal operating hours or during operation partial network during periods of extended normal service, only certain corridors remain open while others must be closed to pedestrians.
  • a metal grid attached to a wall defining one of the lateral sides of the corridor and designed to pivot a position folded against the wall at a position transverse to the wall, so as to temporarily block access to the corridor.
  • this type of massive grid has many disadvantages. Whether they are in a clad position or in a position transverse to the wall, these grilles are permanently visible to pedestrians, which constitutes a permanent negative visual impact, linked in particular to the evocation of the prison domain.
  • these grids constitute an obstacle to the movement of pedestrians along a substantial part of the corridor.
  • this kind of grid needs to be made to measure since the dimensions of each grid are adjusted to the dimensions of the corridor to be closed.
  • US-2005/0211389 discloses a temporary closure device for a passage between a cargo loading dock and the outside.
  • This device comprises a flexible sheet, intended to be unrolled across the passage, from a shaft arranged in a storage pillar of the wound portion of the sheet.
  • This device effectively closes the passage, but is not designed to be implanted in a public place: the handling of the tarpaulin, both to unroll it and to wind it, is not secure in the sense that this manipulation can be by any user, including a malicious user.
  • one side of the pillar is freely open on the outside, which facilitates the degradation of the device, including acts of vandalism, but also because of the accidental introduction of dirt or debris to inside this pillar.
  • WO-A-97/13049 discloses a retractable barrier, comprising an electrified tarpaulin, capable of being unrolled from a tree. When the tarpaulin is wrapped around this tree, it is confined in a one-piece cylindrical box, totally closed around its circumference. Because of its electrifiable nature, it is excluded to arrange this barrier in a public place. In addition, as for the device disclosed in US-2005/0211389 , the manipulation of the barrier of WO-A-97/13049 is not secure.
  • US-B-6575465 discloses a retractable barrier for closing a child's access to a danger zone, without specifying the manner in which the retracted tarpaulin is stored in a housing.
  • the manipulation of the barrier is secured by an audible alarm which detects the release of the tarpaulin vis-à-vis a fastening housing of the free end of the sheet in deployed configuration.
  • the actual release of the tarpaulin is not prevented, so that this barrier is also not able to be installed in a public place to ensure the effective closure of a passage.
  • the purpose of the present invention is to provide a temporary closure device that can be implanted in a public place safely, while being of a pleasant appearance, and simple to install and maneuver and adapting automatically to a large number of different layout configurations.
  • the invention relates to devices for temporary closure of a pedestrian passage such as a corridor, as defined respectively in claims 1 and 4.
  • the device according to the invention thus has a small footprint when the sheet is in its stored configuration, which limits the visual impact of the device, as well as hindering the movement of pedestrians.
  • the device according to the invention adapts to passages of various sizes and configurations. In practice, a single operator is thus sufficient to pass the cover between its configurations stored and deployed when the safe door is open.
  • the shaft locking means or the jamming means of the sheet secure handling of the device prevent a malicious person to unroll the tarpaulin more in the deployed configuration in order to force its crossing, or, if the tarpaulin is in a retracted configuration, these means prevent pulling the tarpaulin to unroll it and thus close the passage while the latter is supposed to remain open .
  • these means prevent a malicious person to unroll the tarpaulin more in the deployed configuration in order to force its crossing, or, if the tarpaulin is in a retracted configuration, these means prevent pulling the tarpaulin to unroll it and thus close the passage while the latter is supposed to remain open .
  • only the operators authorized to unlock the trunk door are able to neutralize the locking means or the wedging means, and thus configure the cover relative to the passage adequately.
  • the installation of the device is easy since it consists essentially in securing the trunk to one of the side walls of the passage to be closed.
  • the tarpaulin can be dressed in a pleasant way, so that when it is deployed, it visually integrates better vis-à-vis the passage.
  • the device is advantageously in accordance with claim 6.
  • the invention proposes to use a temporary closure assembly of the passage, as defined in claim 7.

  • the securing of the post 106 is advantageously obtained by means of a simple manipulation, such as the introduction of the lower end of the post into a specific base 107 integrated in the ground 2 ', followed by a rotation a quarter of a turn of this post to lock the anchoring of the post relative to the base 107.
  • each upper fastener 108 comprises a hook similar to the hook 68
  • each lower attachment 109 comprises a tab similar to the tab 74, advantageously tiltable relative to the rest of the post in the same way that the tab 74 is tiltable relative to its plate 70.
  • the use of the closure assembly 100 consists of "duplicating" the use of the device 10: on the one hand, the device 10 1 , whose trunk 12 1 is secured to the wall 4 ', is manipulated so as to hang its end bar 52 1 in the fasteners 107 and 108 of the corresponding lateral side of the post 106, as shown to the left of the post in FIG. 8, and, on the other hand, the device 10 2 , the trunk 12 2 of which is secured at the wall 5 ', is manipulated to hang its termination bar 52 2 in the fasteners 108 and 109 of the corresponding lateral side of the post 106, as indicated by the arrow F 24.2 to the right of the post in Figure 8.
  • the corridor 1 ' is then closed by, jointly, the tarpaulins 24 1 and 24 2 of the assembly 100, it being understood that the total length of these two sheets thus put end to end, that is to say twice the length L 24 , is greater than the horizontal dimension of the passage 1 '.
  • FIGS. 9 and 10 show a variant of the assembly 100, which differs from the embodiment of FIG. 8 only in the arrangements for fixing the end bars 52 1 and 52 2 . More precisely, rather than providing for the use of the post 106, the variant of FIGS. 9 and 10 presents, at the level of the termination bars 52 1 , 52 2 , specific arrangements.
  • the end bar 52 1 is provided, at each of its longitudinal ends, a cremone 102 1 provided to anchor, down, in the ground 2 'and, above, in the ceiling 3'. These cremones 102 1 are for example reported slidingly and lockable inside the bar 52 1 .
  • the end bar 52 2 has, for its part, a profile 104 2 substantially complementary to an associated profile 104 1 formed by the end bar 52 1 .
  • a first step the operator operates the closing device 10 1 to unroll the corresponding tarpaulin 24 1 in the same manner as for the device 10, until its termination bar 52 1 is located in a substantially median zone from corridor 1 '.
  • the lower and upper cremone 102 1 are then operated to be fixed to the ground 2 'and the ceiling 3', thereby immobilizing the tarpaulin 24.
  • the assembly 100 is then in the state shown in Figure 9.
  • a second step the operator operates the closing device 10 2 to unroll the corresponding tarpaulin 24 2 , until the end bar 52 2 comes in the immediate vicinity of the termination bar 52 1 , as indicated by the arrow F 24.1 in Figure 9.
  • the profiles 104 1 and 104 2 are then engaged in one another in complementarity of shapes, as indicated by the arrow F 104 in Figure 10, so as to fix the bar 52 2 to the bar 52 1 and thus immobilize the tarpaulin 24 2 .
  • the assembly 100 of Figure 8 overcomes an anchoring in the ceiling 3 'of the corridor 1', which allows to use this set for pedestrian passages of great ceiling height.
  • the variant of Figures 9 and 10 has, for its part, the advantage of not being associated with fastening means additional to those carried by the end bars 52 1 and 52 2 , such as the post 106.
