Arm 74 presents a substantially rounded-triangular-shaped end cam 75 cooperating with one ofscrews 85 and which provides for movingblock 77 upwards alongpin 79 whenarm 74 is rotated downwards by pressure onbar 76. The above movement is effected in opposition to aspring 89 which, together with known elastic means (not shown) acting onarm 74, normally maintainsblock 77 contactingbracket 81 to define the idle position ofpanic handle 71. - Since operation of
lock 1 is known as regards key control ofbolt 5 and handle control ofspring latch 6, operation of the lock assembly according to the present invention will now be described in detail only as regards the specific object of the invention. - Very briefly, as of the open position of
bolt 5 shown in Figure 2, whencylinder 50 is rotated by means of a key,slide 7 is moved substantially vertically to rotatebolt 5 into the closed position (Figure 1); andspring latch 6 is maintained in the extracted position byspring 47. - Opening control by means of
panic handle 71 according to the present invention will now be described in detail as of the Figure 1 position oflock 1. - From inside the premises,
bar 76 ofpanic handle 71 is operated to rotatearm 74 and, as described above, moveplate 86 upwards; andappendix 88 ofplate 86 engaged inside opening 67 inplate 55 drawsplate 55 upwards alongwall 2 oflock 1 from the Figure 3 to the Figure 4 position. Purely longitudinal movement ofplate 55 is assured bypins respective slots plate 55 draws upfirst pin 8 engaged insideslot 62, and slidessecond pin 48 alonginclined edge 64.Pin 8, integral withslide 7, movesslide 7 upwards, and guides anticlockwise rotation ofbolt 5 aboutpin 14, so thatbolt 5 moves from the extended position in Figure 1 to the withdrawn position in Figure 2; and first andsecond control pins bolt 5, drawtransmission rods bolts lock 1. - The longitudinal upward movement of
inclined edge 64 slidessecond pin 48 alongslot 65 in wall 2 (Figures 3 and 4);pin 48, integral witharm 41 offirst lever 39, rotateslever 39 anticlockwise aboutpin 28; andarm 41, acting onscrew 43 in opposition tospring 47, movesspring latch 6 from the extended position in Figure 1 to the withdrawn position in Figure 2. - When the pressure on
bar 76 is released,panic handle 71,plate 75 andblock 77 are restored elastically to the idle position in Figure 5 by slidingplate 86 longitudinally downwards together withplate 55, by virtue ofappendix 88 engagingappendix 66 ofplate 55. - Being integral with
arm 41 offirst lever 39, which is restored byspring 47 to the idle position in Figure 1,second pin 48 slides alongslot 65 and up alonginclined edge 64 to restorespring latch 6 to the extended position. - At the same time, the longitudinal downward movement of
slot 62 does not affect the position ofpin 8, so thatbolt 5 andtransmission rods - To open the lock assembly from outside the premises, two different operations must be performed to withdraw bolts, 5, 5a, 5b and
spring latch 6 respectively by means of the key, as described above, and by means of the handle. - More specifically, using the key,
cylinder 50 is rotated so thatdog 52,engaging seat 9 inslide 7, movesslide 7 upwards, guided longitudinally bypin 8 sliding insideslot 62. In exactly the same way as for opening the lock from inside the door, the upward movement ofslide 7 rotatesbolt 5 and withdrawsrods lock 1.Pin 8 sliding freely insideslot 62 has no effect onplate 55, so that the position of panic handle 71 andpin 48 remains unchanged. - To release
spring latch 6 from the outside,pin 28 is rotated using a conventional handle (not shown) prismatically engagingsquare hole 29; andlever 40, also connected prismatically to pin 28, releasesspring latch 6 by acting onscrew 43 by means ofarm 42. In this case, the position offirst lever 39, connected in angularly idle manner to pin 28, and ofpin 48 remains unchanged. - The advantages of the lock assembly according to the present invention will be clear from the foregoing description.
- In particular, operation of the panic handle provides for releasing both the three bolts and the spring latch, thus enabling the door to be opened from the inside even when the key-operated lock is engaged. Moreover, despite being opened easily from the inside, as described above, the lock assembly according to the present invention, by featuring three bolts at three different locations on the door, provides for adequately safeguarding against forced entry using any type of tool inserted between the door and the lock assembly.
- Clearly, changes may be made to the lock assembly as described and illustrated herein without, however, departing from the scope of the present invention.
