Definitions

  • fire-resistant cupboards are being used more and more, said cupboards consisting of fixed walls of fireproof plate material with an insulating and incombustible inner lining, and being provided, at the front side, with at least one folding door consisting of at least two panels and being hingedly connected at one side to.
  • said door being urged by means of a closing means towards the closed position and being adapted to be retained in the open position by means of a locking bolt, said locking bolt being coupled with a tensioning element adapted to be spring-loaded and to be latched in the tensioned condition, and adapted to be released by means of a temperature sensitive actuating element as soon as the temperature outside the cupboard rises above a given value, the released tensioning element then releasing the door locking bolt.
  • Such a cupboard can normally be left open, the or each folding door then being hold in the open position by the locking bolt, thus facilitating placing objects in and taking objects out of the cupboard, especially if this has to be done with both hands.
  • the tensioning element is set free, thus releasing the locking of the door or doors, so that the latter will be closed by the closing means.
  • the contents are, then, isolated from the environment, and, therefore, will not be able to contribute to spreading the fire.
  • the walls should be sufficiently insulating for preventing a substantial temperature rise inside the cupboard within the prescribed time (which should be sufficient for allowing the present personnel to flee), so as to avoid, or at least to defer as long as possible, an explosion of the contentso All this can still be improved by providing in the door joints material swelling on being heated, so that, in the case of fire, hot air or gases are prevented from penetrating into the cupboard.
  • springs are provided in the door hinges which are tensioned when opening the door in question, and, moreover, the door is provided, in particular near the hinges between two panels, with door latches, for keeping the door in the closed position. If the door is closed as a consequence of a temperature rise, the spring loaded door latches should be allowed to snap in the locking position when reaching the closed position of the door, said bolts serving for keeping the doors closed also at an internal rise of pressure. In order to ensure this snapping action under all circumstances, the final velocity of the door during closing should be high, and thus the closing spring tension in the open position should be accordingly high. This makes difficult the opening of the door against the gradually increasing spring force, and the fast closing of the door with a heavy blow can be dangerous for people standing in the neighbourhood, also if the door has to be closed under normal conditions.
  • the invention provides an improved cupboard of this kind, which is characterised in that the closing means for a folding door is formed by a vertically displaceable weight which is coupled with the folding door by means of a cable guided by means of rollers, said folding door being, in particular, not provided with a latch, and, the closing weight being sufficiently heavy for keeping the folding door closed.
  • Isolating said venting aperture is preferably obtained by extending the lateral walls beyond the rear wall, so that, together with a wall of the building against which the cupboard is placed, an air duct is formed which is protected against direct fire action.
  • Said wall extensions are, in particular, formed by channels in which the door closing weights are arrangVdY
  • the door is, preferably, not guided at all at the lower side, which is made possible by the absence of door latches, Preferably a fixed claw is provided at the lower side, behind which a pin mounted near the front edge can grip when approaching the closed position, so as to retain the door outwards in the closed condition, thus counteracting rattling and providing a certain counter pressure when sealing strips swelling or foaming on being heated come into action.
  • Laboratory cupboards are, generally, connected to a suction duct so as to allow to remove vapours present in the cupboard, in which duct a security valve can be provided which suppresses the suction at a temperature rise, so that, when the door or doors are closed in the case of fire, no negative pressure will occur inside the cupboard.
  • this security valve is preferably constructed as a drop valve which is directly coupled with the tensioning element of the door retaining locking bolts and is kept open in the tensioned condition thereof, which allows a simple and dependable construction.
  • a handle For opening the door, generally a handle is mounted near the hinge connection between two door panels.
  • the handle is preferably constructed as a continuous bar situated at a distance of the panel in question, which, because of the absence of a door latch, can be held, if necessary, by two hands, and can be situated at such a distance from the door panels that there is no risk that fingers get between the door panels.
  • the cupboard sLown in the drawing comprises fixed walls, namely lateral walls 1, an upper wall 2, a bottom wall 3 and a rear wall 4, the front side being open and adapted to be closed by means of two folding doors each consisting of two panels 5 and 6, the panels 5 being connected to the fixed cupboard parts by means of hinges 7. Near their free terminal edges the panels 6 are, at their upper sides, guided in the usual manner in a guiding channel (not shown), but at their lower sides no guiding means are present.
  • locking means diagrammatically shown at 8 are provided which retain the doors in the open position, and which are kept active by means of a spring loaded tensioning means with a tensioning handle 9 until the tensioning means is released by means of a heat sensitive element 10.
  • the doors are each urged towards the closed position by means of an associated weight 11 which is connected to the door by means of a cable 13 guided by guiding rollers 12.
  • the cable 13 can, for instance, be fixed to a free terminal edge of a door panel, but it is also possible to lead this cable over a pulley connected to the hinge axis 7.
  • a pin 14 is provided which, when approaching the closed position, can grip behind a claw 15, so that this terminal edge in the closed position will be retained against outward forces also at the lower side.
  • an air suction connection 16 is provided which is represented in section on a larger scale in Fig. 2, which connection is intended to be connected to a suction duct provided with a blower, and communicates via an aperture 17 with the interior of the cupboard.
  • the aperture 17 can be closed by means of a drop valve 18, which valve is provided with an eye 19 into which an arm 20 is inserted which is directly fixed to a rod 21 to which the tensioning handle 9 is connected.
  • the valve 18 is lifted.
  • the tensioning means is unlatched by a temperature rise, the rod 21 is rotated so that the valve 18 is closed.
  • an air suction aperture 22 is provided in the rear wall 4 near the lower side thereof.
  • This aperture can also divert outwards possible pressure rises inside the cupboard.
  • the latter is isolated in that the lateral walls 1 extend beyond the rear wall 4, so that, together with the wall of the building against which the cupboard is placed, a protected air duct is defined.
  • a duct can be obtained.
  • These extending parts of the lateral walls 1 are, in particular, formed by channels 23, in each of which a weight 11 is received so that, for these weights, no interior cupboard space is required.
  • shelves are provided, but the latter can impede the inner ventilation. Therefore the shelves are, preferably, supported in the manner of Fig. 3 by means of stiles 24 which are situated at some distance from the adjacent wall, so that a passage 25 next to the shelve 26 fixed thereto remains free.
  • the door panels 5 are provided with a handle bar 27 extending over a substantial part of the height of the panel in question, and serving for pulling the door open.
  • This handle bar is situated at some distance from the panel, thus avoiding that fingers can get jammed in the joints between the panels 5 and 6 if the door would suddenly close again.
  • Such a handle bar can be easily gripped by two hands, irrespective of the height of the person in question.
  • a constant torque can be obtained by connecting the cables 13 to a pulley connected to the door hinge in question.
