Definitions

  • t presenthautomatic door openers are generally controlled by carpets provided with electric contacts which are closed when the carpet is walked on. Such contact carpets are comparatively expensive and are furthermore subject to trouble through condensed water, dust and the like. Therefore it has been proposed to make use of switching systems controlled from a pneumatic carpet. Such switching systems, however, have not been able to establish themselves, because with them, for reasons explained more closely hereinafter, under certain circumstances, the doors closed involuntarily.
  • I-t relates to ⁇ a switching system controlled from a pneumatic carpet, having piping leading to the pressure chamber of the pneumatic carpet and connected to a pneumatic switch and la member adapted to permit slow pressure-equalization between the pressure chamber and atmosphere.
  • This switchin-g system is characterized by the provision of a stop member in the run of the piping of the pressureequalizing member, and that this stop member, as the pneumatic switch responds to suddenly increased pressure in the pressure chamber of the carpet, is closed through this switch, and consequently stops the pressureequalizing.
  • the stop member can be closed direct or indirect upon response of the pneumatic switch. It may namely be formed by an electrically-actuated valve closed together with the switch, or else by a valve which is mechanically, for instance kinematically, connected to a door opener and kept closed by the d-oor opener as long as the latter is energized through the pneumatic switch.
  • such a switching system may also be used for electric-light switches in corridors, for water-ushing in urinals -and for other purposes.
  • a pneumatic carpet 1 which is placed in front of a door (not shown) includes in the usual manner rubber or plastic flexible tubing 2, that forms the pressure chamber of the carpet and is closed at one end, but connected at the other to thin piping 3.
  • Piping 3 at one end has joined thereto piping 4 leading to a pneumatic switch 5, and at the other end piping 6 which, through an electrically-actuated valve 7 and a tine regulating valve 8, opens to free atmosphere.
  • the pneumatic switch comprises a pneumatic chamber 9 bounded by a diaphragm 10 which is connected mechanically to a movable contact 11 facing a stationary contact 12.
  • Switch 5 lies in the run of an electric line leading from an input terminal 13 to an output terminal 14.
  • the other input terminal 15 is connected direct to the other output terminal 16.
  • Valve 7 is connected to the lines leading to the output terminals 14, 16 so as to lie parallel to the output circuit.
  • the input terminals 13, 15 are connected to the electric mains, the output terminals 14, 16, say, to a door opener.
  • the terminals 13 and 15 represent the connection points to the power line, and the terminals 14 an'd 16 represent the connection points, on which the control-gears for opening the door or for performing a corresponding function are connected.
  • pneumatic carpet is to be construed in the widest sense; especially the carpet may be very narrow, so that functionally it may, for instance, replace the usual contact thresholds in street signalling plants.
  • the tine regulating valve 8 may be replaced by .a stopper screwed into the electrically-actuated valve 7, in which stopper there is provided a tine bore of, say, 0.25 mm. in diameter, through which pressure-equalization takes place as long as the valve is open.
  • a stop member which is controlled through a mechanical linkage by the door opener, and is closed when the door opener, excited by the closing of switch 11, has opened the door. Also in this case the door remains open until the user has again left the pnuematic carpet 1, because the closing of the stop member prevents pressure equalization and thus, with carpet loaded, switch 11 remains in the closed position.
