Definitions

  • the invention concerns safety locks for doors provided with an emergency handle for preventing panic.
  • Presently known anti-panic locks comprise a horizontal handle that projects from the inside face of the door. Translating under pressure from the front, said handle opens the lock even if it has been closed with a key. If there is pressure from a crowd of panic-striken people it is sometimes difficult, or even impossible, to open the door even when released by the emergency handle. Emergency situations can in fact complicate even the simplest operations.
  • the present invention offers a decisive contribution to opening a door in an emergency as will be explained below.
  • the emergency handle determines movement of said bolt plate against the base plate.
  • Said translation determines a break in mechanical connection between said bolt plate and the bolt in the ordinary lock.
  • This device comprises a pin,fixed to the base plate, on which a small cylinder governed by a spring can freely rotate, said cylinder exhibiting an orthogonal extension subject to action by a tie rod fixed to the bolt of the ordinary lock.
  • a locking tooth is mounted on the bolt plate and when the bolt plate translates said tooth moves as well and becomes aligned with the plane of the above extension provoking interference with the axis of the cylinder pin.
  • said extension there is a radial slit wider than the size of the locking tooth.
  • the effect of rotating the arms, at the extremities of the emergency handle and by which it is articulated onto the base plate, is to make the emergency handle rotate a vertical shaft substantially parallel to the bolt plate.
  • On said shaft is an arm with a hook at its end, said hook penetrating inside a longitudinal slot in the bolt plate.
  • An intermediate vertical rod is fixed to said arm. Pressure by this rod on the bolt plate makes it move towards the base plate overcoming resistance opposed by springs, causing the locking tooth to move away from the extension.
  • the hook on the end of the arm meanwhile presses against the end of the slot causing the bolt plate to translate and so release the means that fix the door to its frame.
  • the door can therefore be opened by simply exerting pressure on the emergency handle.
  • the vertical shaft carries a short arm whose position corresponds to that of a pane of glass, replaceable, mounted on the base plate. Rotation of said shaft caused by movement of the emergency handle will lead to this pane of glass becoming broken.
  • the pane itself is associated to an electric sensor that warns a control centre if the glass has been broken.
  • the bolt plate exhibits a short pin that presses on a sensor so informing a control centre of the movement made by said plate.
  • the invented lock can comprise within it an ordinary lock of any kind.
  • the mechanism described enables connection to be made between an ordinary lock and the special devices that ensure easy opening in an emergency as explained.
  • the invented lock can be included in any alarm system; it will guarantee maximum protection and certainty of immediate and easy opening from the inside if an emergency arises.
  • the safety lock 10 with emergency handle 15 is mounted on the door 60 (Fig. 5).
  • the lock comprises a base plate 11 mounted on the inside of the door 60 so that the arms 72 of the translating handle 15 pass through the slits 68 in the door. Said arms 72 are articulated on the supports 32 of the base plate II.
  • the articulating means comprises trunnions 33 held in place by split pins 34.
  • the door 60 is locked by a bolt plate 12 which functions by means of pins 55, at its ends, on the corner pieces 56 fixed to a bolt with heads that penetrate in the cavity of the door frame to hold it firm.
  • the pins 55 act on the corner pieces through slots 57.
  • the bolt plate 12 can translate longitudinally guided by the slots 61 through which pass pins 17 with threaded ends 19 fixed to the base plate 11, said bolt plate being served by the stop block 97.
  • the coaxial springs 18 hold the plate 12 against the washers 20, in turn held in position by the nut 21.
  • Translation of the bolt plate 12 can be determined by the handle 13 that freely turns on the pin 69 fixed to the base plate 11, said handle having an internal arm 66 on which is mounted a fork 67 inside which penetrates the small pin 95 fixed to the bolt plate 12.
  • a washer 42 and nut 43 are fitted onto the pin 44.
  • the bolt 39 of lock 14 assumes two positions according to whether the lock is closed ( Figures 1,4) or open Figures 2,3), namely positions 39 or 39'.
  • Action by the rod 48 causes the slit 58 in extension 41 to take up its respective positions 58 or 58'.
  • Pins 77 are fixed on the bolt plate 12 and on these pins the pair of couplings 75 freely slide connected by bar 78.
  • pins 74 aligned parallel to the bolt plate 12; these penetrate through slots 73 made in the arms 72 of the translating handle 15.
  • bar 78 In bar 78 is a slot 82 through which penetrates pin 83 of arm 84 fixed to the shaft 16 that freely turns on supports 30 with their heads 31.
  • Said shaft has a second arm 86 forming a hook 88 which carries a rod 87 parallel to the shaft 16, itself parallel to the plate 12.
  • the hook 88 fits inside the slot 62 in the plate 12 (Fig.1). If an emergency arises pressure on the translating handle 15, as in Figures 6 and 4, determines translation of said handle towards the door 60 with rotation of arms 72 which, by means of slots 73 and pins 74, pull the bar 78 towards the bolt plate 12.
  • the bolt plate 12 therefore assumes the position seen in Figure 4 corresponding to release of the door since the bolt fixed to the corner pieces 56 is obviously drawn along by the bolt plate 12 itself.
