Definitions

  • the present invention concerns apparatus for selectively closing or at least partially closing a passageway.
  • apparatus is already in widespreaduse for controlling entry to an area or enclosure to which entry may only be made by persons authorized in some way. This authorization may be by the purchase of a ticket or the payment of a toll, for example.
  • apparatus of this type is for controlling entrance to an underground railway system.
  • the barrier is closed to prevent the entry of such a person. Otherwise, being permanently open, the barrier permits a high throughput.
  • One disadvantage of the existing forms of barrier is that a slow closure may not be sufficiently rapid to prevent entry of a person or article to be excluded, while a rapid and possible violent closure may cause injury or damage to the person or article to be stopped.
  • FIG. 1 is a transverse section through a first form of barrier
  • FIGS. 3, 4 and 5 show three forms of inflatable pocket for use with the barrier.
  • the inflation arrangement includes a compressed air chamber 14 connected to the interior of the pocket 4 by a pipe 8 connected to an inlet 12 of the chamber 14 through a valve 10.
  • a device 22 for cutting down the noise caused by sudden inflation of the pocket 4 is mounted in pipe 8 between the valve 10 and the pocket.
  • the pipe 8 ends in a device for directing air issuing from chamber 14 uniformly over the interior of the pocket 4, to ensure a uniform inflation. Two forms of device are shown in more detail in FIGS. 4 and 5.
  • the pockets 4 and 5 are selectively inflatable to close off the passageway 1, and pockets 104, 105 may close off passageway 101.
  • the barrier includes a control system 112 for bringing about inflation and deflation of the pockets as and when necessary.
  • FIG. 1 shows only the connections between systems 112 and valves 25 and 11 in partition 3.
  • an enabling signal is applied to an input of system 112 by an output of the device 110.
  • the device 110 discriminates between persons who are permitted to pass through the barrier and those who are not permitted to pass.
  • pockets 4 and 5 are deflated and lie within their respective recesses 6 and 7 to leave the passageway clear.
  • Valves 10 and 11 are closed.
  • Valves 24 and 25 may be either closed or connecting the respective pockets to their respective expansion chambers.
  • the passageway l is clear for the passage of a person or vehicle.
  • the mating faces of the two pockets are provided with flexible projections 21 directed towards the entry of the passageway l and serve to prevent forcible separation of the two faces when in contact.
  • each pocket may have a height of some 60 centimeters and thickness of some 40 centimeters, and the pressure in the fully inflated pockets may be of the order of 300 grammes per square centimeter.
  • a single valve 10 is mounted between the inflation pipe 8 and the pipe 12 leading to the compressed air chamber 14.
  • An exhaust pipe 16 also leads to the valve 10, which is selectively operable to connect the pocket 4 to the compressed air chamber 14 or the expansion chamber 18.
  • FIGS. 4 and 5 show schematically two arrangements for ensuring uniform distribution of the compressed air during inflation of the pockets.
  • a set of short pipes 81 extend partially into pocket 4, each pipe 81 being connected at one end to the conduit 8 and having its other end directed towards the interior of the pocket.
  • the arrangement of the pipes 81 provides the uniform inflation. With this arrangement, the high-pressure air from pipe 8 does not impinge on a restricted area of the pocket, which might lead to excessive wear or damage, but is distributed in a substantially uniform manner over most of the internal surface of the pocket which will be uniformly inflated and well stretched.
  • the pipes 81 may be rigid, in which case they will not extend outside the recess 6 in partition 2.
  • these pipes 81 may be flexible, in which case they may extend beyond the recess and terminate close to the inside walls of the pocket. Their free ends may be connected together and to the side walls of the pockets so as to guide them to a required position during inflation. This may also be done by making those portions of pipes 81 nearest pipe 8 rigid or partially rigid.
  • the stream of compressed air may be evenly distributed by means of a flat grill 82 mounted inside the pocket 4 and attached to its side walls.
  • the airstream from pipe 8 is divided into a number of sub-streams each passing through one perforation of the grill.
  • the arrangement of the perforations and their respective dimensions may be so chosen as to obtain the best distribution of the air for the shape of the grill is made of a flexible material,.it may be mounted close to the forward face 41 of the pocket, or it may be rigid in which case it would be mounted close to the rear face, as shown in FIG. 5. In this case it will remain within the recess 6.
  • the grill may be plane, as shown in FIG. 5 or may have aform corresponding to that of the fully insulated pocket or at least the front wall of the pocket when fully inflated.
  • FIGS. 4 and 5 While in FIGS. 4 and 5 only pocket 4 has been described in detail, it will be appreciated that the cooperating pocket 5 is identically arranged.
  • FIG. 6 shows a barrier suitable for use where the direction of movement in the passageway may be reversed.
  • the barrier has two sets of pockets 50, 51 and 40, 41.
  • At one end of the passageway l is a device 43 for testing the validity of a ticket or the like with an arrangement 44 for detecting the passage of a person.
  • the opposite end of the passageway is provided with a similar validation device 53 and person detector system 54. These may be as described in more detail above.
  • the detection system 43, 44 maybe associated with either set of pockets, as may the system 53, 54. For example, if system 43, 44 controls pockets 40, 41, entry in the direction shown by arrow 45 is controlled by these pockets. System 53, 54 with pockets 50, 51 would then control entrance in direction shown by arrow 55.
  • a single pocket may be used where the width of the passageway is compatible with providing a firm barrier with only one pocket.
  • valved conduit means includes a device for suppressing noise occurring on inflation or deflation of the pocket.
  • said distribution device comprises a set of pipes joined at a set of first ends to said inflation conduit means, the set of second ends of said pipes being directed towards the internal surface of the pocket so as to provide said uniform distribution of pressure.
