Definitions

  • the present invention relates to a door-swinging device which makes it possible to open and close heavy doors with a reduced effort.
  • Doors which are used to close vaults or other enclosures containing large quantities of radio-active materials must be provided with very thick lead or concrete protective linings.
  • the device according to the present invention is essentially characterized in that it makes use of a fluid lubricant under variable pressure, which is introduced between the members on which the door is suspended and rotated, namely, between the member-s fixed to the door frame, and the members attached to the door itself; the pressure fluid forms a lubricating layer, which avoids direct contact between the members.
  • the eifort required to displace a door depends notably on the frictional forces between surfaces which are placed in contact with a pressure which may be very high; by interposing a fluid layer, for example a layer of oil, between these surfaces, the frictional forces, and consequently the effort necessary to swing the door, are considerably reduced.
  • the device may be employed for doors weighing several tons and it makes it possible to open and close them by exerting a manual force of a few kilograms.
  • the fluid pressure is provided by a device mounted on the door, for example a piston pump, which is actuated by a hand lever, the lever being also used as a handle to move the door by pulling or pushing it; the fluid under pressure is conveyed by means of conduits in the movable members attached to the door.
  • a device mounted on the door for example a piston pump, which is actuated by a hand lever, the lever being also used as a handle to move the door by pulling or pushing it; the fluid under pressure is conveyed by means of conduits in the movable members attached to the door.
  • the oil under pressure is equally used to lock and unlock the door by any suitable means such as, for example, hydraulic jacks which act on the locking bolts through the intermediary of levers, the bolts being mounted on the door and being withdrawn into the door when the fluid i-s'at a sufliciently high pressure.
  • FIGURE 1 is a schematical general view of a door mounted on hinges and provided with the device according to the invention
  • FIGURE 2 is a section on an enlarged scale of a hinge such as is used according to the invention.
  • FIGURE 3 is a fragmentary front elevation of a door including the device according to the invention.
  • FIGURE 4 is a section along line IVIV of FIG- URE 3.
  • the door 1 has mounted therein a pump 2, actuated by a hand lever 3 through the intermediary of a linking lever 4.
  • the pump forces oil under pressure into a hydraulic circuit, indicated by thick lines in FIGURE 1, and including a throttle 5 which keeps the circuit under pressure for a lapse of time, after the lever 3 has been actuated.
  • the oil is supplied on one side to the hydraulic jacks 6A and 6B which act respectively on levers 7A and 7B on the bolts 8A and '8B, which are urged into locking position by springs 9A and 9B; on the other side the oil is fed to the hinge assemblies 10A and 10B.
  • each hinge assembly comprises a hinge pin 11 in the form of a shaft, which is received on a hinge bearing member 12 in the form of a hollow cylinder, the end of the pin 11 resting on a bearing 13 which may be a ball bearing, it being understood that the balls have a supporting action only when the oil is not under pressure.
  • the pin 11 has a passage 14 therethrough, which is connected to the hydraulic circuit at its upper end.
  • the hinge member 12 is mounted on the door frame by means of an attachment or sealing plate 15.
  • the hinge pin 11 is fixed by means of screws 16 to a sleeve 17 mounted on the door by a plate 18.
  • a packing ring 19, provided with packing joints or segments 20, is screwed on the hinge pin 11 to provide a tight seal for the oil between the pin and the hinge bearing member.
  • the oil circuit is placed under pressure and the door is swung to its closed position.
  • the drop in the oil pressure causes locking of the door.
  • the locking bolts and the corresponding clasps have a frustoconical form which strictly positions the door, even in cases where a sealing joint must be compressed.
  • the throttle 5 retards the return of the oil, in such a way that it is not necessary to actuate continuously the lever 3 to maintain the pressure during the swinging of the door.
  • the throttle 5 may be constituted, for example, by a capillary tube, one end of which is connected to the outlet of the pump 2, the other end being connected to the tubing of the hydraulic circuit.
  • the device according to the invention is utilized for swinging doors which close the sealed enclosures or vaults of plants for the treatment of radio active materials.
  • FIGURES 3 and 4 Such doors are double, each individual door, as shown in FIGURES 3 and 4, consisting of a framework of U- beams 21, 22, 23, 24, 25, and 26, covered with sheet metal plates 27 on both sides (FIGURE 3 shows the door with the front cover plate removed).
  • the rear face 28 of the door is covered with a lining 29 of cast lead of sufficient thickness to absorb the radiations emitted by the contents of the vault.
  • the hinge pins 11 are Welded at 30 on the vertical beam 21.
  • the pump is located between the beams 23 and 24, and a shutter 31 is provided for maintenance purposes.
  • An actuating lever 3A situated on the front face of the door, is mounted on the cover plate 27; a second actuating lever 3 B, mounted on the cover plate 27 of the rear face of the door is covered by a lead cap 32 provided with a groove 33 in which moves the lever; the two levers actuate the pump in the same manner.
  • a dust seal is provided by packing strips 35 located in grooves 36 in the flange 34 and in the wall 37.
  • each of said assemblies comprising a vertically disposed hinge pin fixed to the door, a hollow hinge bearing member surrounding said pin fixed to the door frame, fluid sealing means between said pin and the top of said member, means for supplying a fluid under pressure mounted on said door, and conduit means from said supply means for said fluid, an axial passage through said hinge pin and means connecting said conduit means to said passage.
  • a heavy door hinge assemblies with horizontal contact surfaces for said door, means on said door for supplying a fluid under pressure to said contact surfaces so as to form a layer of fluid between said surfaces to thereby reduce the effort required to swing said door, at least one manually actuated lever for said supply means mounted on at least one face of said door, locking means for said door and fluid conduit means connecting said locking means with said fluid pressure means, said locking means being adapted to unlock when subjected to fluid pressure.
