Definitions
- the invention concerns safety locks especially those provided with an emergency handle for preventing panic.
- Presently known anti-panic locks comprise a horizontal r handle that projects from the inside face of the door.
- the above invention offers a decisive contribution to opening a door in an emergency as will be explained be- low.
- Subject of the invention is a safety lock for doors with a horizontal bar-shaped translating emergency han ⁇ dle, a bolt plate on which is mounted an ordinary handle of the lever type, supported by a heavy base plate and an ordinary lock.
- this break in connection permits longitudinal translation of said bolt plate consequently releasing the door even if locked in the usual wa .
- 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.
- An intermediate vertical rod is fixed to said arm. Pressure by this rod on the bolt plate makes it move to- wards the base plate overcoming resistance opposed by springs, causing the locking tooth to move away from the extensio .
- 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 pres ⁇ sure 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 emer ⁇ gency arises. Presence of the pane of glass, which breaks when the emergency opening is made, and of the sensors both on the pane and in the bolt plate, make it possible to ex ⁇ ert full control even in an emergency situation.
- the use of stainless steel for all moving parts of the lock guarantees a high level of long-term, effieiency .
- Fig.1 The safety lock with lever-type handle and emer ⁇ gency handle, shown locked and with the emergency handle idle, an internal perspective view.
- Fig.2 The same as Fig.1, unlocked.
- Fig.3 The unlocked position in Fig.2 with the door re ⁇ leased by the lever handle.
- Fig.4 The lock in the locked position with the door re- leased by means of the emergency handle.
- the safety lock 10 with emergency handle 15 is mounted on the door 60 (Fig. 5).
- the keyhole 24 of an ordinary lock 14 and usual type of turning handle 13 are shown in the drawing.
- 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 11.
- 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 ca ⁇ vity 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 be ⁇ ing served by the stop block 97.
- the coaxial springs 18 hold, the plate 12 against the wa ⁇ shers 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 I I, 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.
- said extension is a radial slit 58 and a hole 47 through which penetrates arm 49 and rod 48 mounted on the bolt 39 of the lock 1 .
- Pins 77 are fixed on the bolt plate 12 and on these pins the pair of couplings 75 freely slide connected by bar 78. Fixed to said couplings are 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 ith 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 paral ⁇ lel to the plate 12.
- the hook 88 fits inside the slot 62 in the plate 12 (Fig. l). 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.
