- the drawing organ 14 is more precisely in the form of a pin fixed orthogonally to the first plate 10.
- the second take-up profile 13 comprises more precisely a convex corner of the perimeter edge of the first plate 10.
- the first plate 10 is interposed between the pawl 7 and the rotatable element 8 for driving the latch 6.
- the first plate 10 in particular has a flat elongated conformation, is arranged parallel to the flat sides 2c, 2g of the case 2 and is pivoted on the case 2 with a rotation axis that is orthogonal to the flanks 2c, 2g of the case 2.
- the first plate 10 is interposed between one of the two flat flanks 2c, 2g of the case 2 and the support plate 4 of the bolt 3.

- the elastic pushing element 11 comprises a helical spring 17 and a stem 18 engaged slidingly in a diameter hole 19 of a rotation pin 20 defining also the fulcrum 15 of the pushing element 11.
- the stem 18 has a head 18a permanently engaged in a seat 21 provided on the perimeter edge of the first plate 10.
- the spring 17 winds around the stem 18 and is compressed between the head 18a of the stem 18 and the rotation pin 20.
- the special arrangement and construction of the elastic pushing element 11 enables a rotation force to be applied that is permanently coplanar with the first plate 10.
- the first plate 10 is thus not subjected to torsional stress that could, if present, alter the lying plane of the first plate 10 with consequent risk of malfunction of the panic lock 1.
- the elastic pushing element 11, during rotation of the first plate 10 by the pawl 7 that engages with the first profile 12, is able to assist the action of the pawl 7.

- the flexible organ 40 in particular is shaped as an "S"-shaped plate, having a pivot 40' pivoted in the hole 60 of the support plate 4 of the bolt 3, and a tooth 40" engaging the pawl 7.
- the elastic energy accumulated by the flexible element is then returned by the flexible organ 40 to the pawl 7 in the step of disengagement of the pawl 7 from the first shaped perimeter take-up profile 12 of the first plate 10 so as to facilitate the detachment of the pawl 7 from the first shaped perimeter take-up profile 12 of the first plate 10.
- the version for a two-wing door or window provides with respect to the basic mechanism an additional component formed by an extraction plate 22 for extracting the drawing organ 14 from the first end portion 5b of the slot 5.
- the extraction plate 22 has a protrusion 23 for taking up the movement that is positionable in front of the bolt 3 and a slot 24 wherein the drawing organ 14 is slidable.
- the extraction plate 22 is flat and is arranged parallel to the support plate 4 and on the side of the support plate 4 opposite the side facing the first plate 10.

- a suitable ejector present in this device positioned at the bolt 3, is pushed outwards to exert directly on the protrusion 23 a retraction force to retract the bolt 3 inside.
- the selective translation of the extraction plate 22 with respect to the support plate 4 produces the complete alignment between the intermediate portion 5a of the slot 5 and the intermediate portion 24a of the slot 24 that were originally partially staggered and, by virtue of the engagement of the wall of the slot 24 with the drawing organ 14, an oscillation of the first plate 10 owing to which the drawing organ 14, initially positioned in the first end portion 5b of the slot 5 and in the first end portion 24b of the slot 24, moves to the intermediate portion 5a of the slot 5 and to the intermediate portion 24a of the slot 24.
- the ejector (which is not shown) continues its stroke, exerting the force of retraction directly on the front face of the bolt 3.
- the version of panic lock 1 with the function of recalling the latch 6 by the key provides, with respect to the basic mechanism, an additional component formed by a longitudinal lever 25 for retracting the latch 6 having a first end constrained on the rotatable element 8 for driving the latch 6 and a second end longitudinally opposite the first end having a perimeter profile 26 for taking up the movement from the pawl 7.
- the longitudinal lever 25 for retracting the latch 6 is in turn formed by a flat plate parallel to the first plate 10 and positioned between the latter and one of the flat flanks 2c, 2g of the case 2.
- the longitudinal lever 25 for retracting the latch 6 is more precisely pivoted on the rotatable element 8 for driving the latch 6 and has an oscillation angle limited for example by suitable interference surfaces.

- the locking peg 49 is used to make the inner rotor 27 and the outer rotor 27' constrained with the rotatable element 8.
- the pawl 7 when the pawl 7 is driven by the key, in addition to engaging and rotating the first plate 10 that controls the retraction of the bolt 3, the pawl 7 engages and drives the longitudinal lever 25, which in turn transmits movement to the rotatable element 8, which lastly retracts the latch 6.
- the panic lock 1 is devoid of a grip for driving the latch from the outer side of the door or window.
- the version of panic lock 1 with the function of enabling or disabling the grip that operates on the outer side of the door or window provides, with respect to the basic mechanism, also a transmission lever 28 interacting with the movement receiver and distributor for switching between a connection state and a disconnection state of the outer rotor 27' from the rotatable element 8 for driving the latch 6.
- the locking screw 48 is used that fixes the sole inner rotor 27 to the rotatable element 8 for driving the latch 6.

- the main difference with respect to the previously disclosed version of panic lock consists of limiting the maximum angle of rotation permitted to the plate 30" with respect to the first plate 10.
- the plate 30" has the same conformation as plate 30' and the slot 58" is less long than the slot 58'.
- the key remains imprisoned in the cylinder of the lock.
- the pawl 7 engages the second plate 30" and rotates the second plate 30" in the direction opposite the preceding direction, and the cam 31" of the second plate 30" rotates the transmission lever 28 in the opposite direction to the preceding direction until the disengagement thereof from the relative engagement seat 51 is brought about.

- With reference to the cited figures, a panic lock for a door or window is shown that is indicated overall by the
reference number 1. - As will become clearer below, the invention provides a basic mechanism that is common to all locks.
- The various lock versions incorporate the basic mechanism and additional components for performing the functions to which they are assigned.
- The
panic lock 1 comprises a case 2 with a substantially parallelepiped conformation formed by abox 2a and acover 2b, wherein thebox 2a defines a firstflat flank 2c of the case 2, a flatrear side 2d of the case 2, upper and lowerflat planes cover 2b defines a secondflat flank 2g of the case 2 parallel to the firstflat flank 2c. - The
box 2a and thecover 2b lastly define in combination afront side 2h of the case 2. - The case 2 is housable in a seat that opens on the front side of the door or window and penetrates in a front-back direction into the thickness of the door or window (not shown).
- In a known manner, the case 2 houses a
bolt 3 and alatch 6 and has ahousing seat 34 for a cylinder (not shown overall) provided with arotatable pawl 7 for driving thebolt 3 and a slit (not shown) for introducing a key (not shown) to drive thepawl 7. - In a known manner, the
bolt 3 is translated in the front-back direction of the case 2 between a position of extraction from the case 2 through a window provided on thefront side 2h of the case 2 and a position of complete retraction into the case 2. - In particular, the
bolt 3 is supported in a fixed manner by asupport plate 4 coupled in a translatable manner with the case 2 by appropriate linear guides including alongitudinal slot 35 of thesupport plate 4 engaged by aguide pin 36 fixed in the case 2. - The
support plate 4 is flat and is arranged parallel to theflat flanks - In a known manner, also the
latch 6 is translated in the front-back direction of the case 2 between a position of extraction from the case 2 through a window provided on thefront side 2h of the case 2 and a position of complete retraction into the case 2. - In particular, the
latch 6 is supported in a fixed manner to the head of arod 37 that is contrastingly translatable and through the action of aspring 38, in particular atorsional spring 38 pivoted on the case 2 and having a drive arm engaged with aflange 39 of the tail of therod 37 and a reaction arm resting on the inner wall of the case 2. - The
panic lock 1 provides arotatable element 8 for driving thelatch 6. - The
drive element 8 for driving thelatch 6 is formed by a shaped plate pivoted on the case 2 with a rotation axis that is orthogonal to theflanks - The
drive element 8 for driving thelatch 6 has aridge 45 for driving thelatch 6, theridge 45 engaging the side of theflange 39 of the tail of therod 37 opposite the side engaging thetorsional spring 38. - On opposite sides of the
rotatable element 8 for driving thelatch 6 aninner rotor 27 having anengagement seat 46 for a square pin (not shown) for driving thelatch 6 from the inner side of the door or window, and an outer rotor 27' having an engagement seat 46' for a square pin (not shown) for driving thelatch 6 from the outer side of the door or window are positioned. Theinner rotor 27 and the outer rotor 27' are rotatable coaxially with therotatable element 8. - The
inner rotor 27 and the outer rotor 27' are in particular contrastingly rotatable through the action ofelastic means 47 between two end positions defined by twoend strokes - The
engagement seats 46, 46' for the square pin are centred on the common rotation axis of theinner rotor 27 and of the outer rotor 27'. - The
inner rotor 27 is fixed to therotatable element 8 and, depending on the application, also the outer rotor 27' can be fixed or not fixed to therotatable element 8. - If the
inner rotor 27 and the outer rotor 27' are solidly constrained with therotatable element 8, alocking peg 49 is for example provided that joins the three parts together fixedly. - If on the other hand only the
inner rotor 27 is solidly constrained with therotatable element 8, alocking screw 48 is for example provided that joins the two parts together fixedly. - In certain versions of the lock, the square pins for driving the
latch 6 from the inner side and from the outer side of the door or window can be made of a single piece, in other versions of the lock the square pins for driving thelatch 6 from the inner side and from the outer side of the door or window are on the other hand structurally separate and independent. -
Rotors 27 and 27' can be inside or outside indifferently, as a function of the orientation of the latch 6 (rotated by 180°). Conventionally, the inner rotor is indicated by thenumber 27 and the outer rotor is indicated by the number 27'. - Advantageously, the
panic lock 1 also provides a movement receiver and distributor comprising at least one rotatablefirst plate 10 pivoted on the case 2. - The
first plate 10 comprises a first shaped perimeter take-up profile 12 for taking up the movement from thepawl 7, a second shaped perimeter take-upprofile 13 for taking up the movement from acam 9 present on theelement 8 for driving thelatch 6, and adrawing organ 14 for drawing thebolt 3 that is slidable in a slot 5 of thebolt 3. - The drawing
organ 14 is more precisely in the form of a pin fixed orthogonally to thefirst plate 10. - The second take-up
profile 13 comprises more precisely a convex corner of the perimeter edge of thefirst plate 10. - The
first plate 10 is interposed between thepawl 7 and therotatable element 8 for driving thelatch 6. - The
first plate 10 in particular has a flat elongated conformation, is arranged parallel to theflat sides flanks - More precisely, the
first plate 10 is interposed between one of the twoflat flanks support plate 4 of thebolt 3. - The elongated conformation of the
first plate 10 is such that the distance of the drawingorgan 14 from therotation fulcrum 16 of thefirst plate 10 is greater than the maximum between the distances of the first take-upprofile 12 and of the second take-up profile13 from therotation fulcrum 16 of thefirst plate 10. - The slot 5 of the
bolt 3 has anintermediate portion 5a shaped for the reversible movement of thebolt 3 by the drawingorgan 14, afirst end portion 5b shaped for locking thebolt 3 by the drawingorgan 14 in the end stroke position for extraction from the case 2, and asecond end portion 5c shaped for locking thebolt 3 by the drawingorgan 14 in the end stroke position for retraction from the case 2. - The slot 5 has the oblique
intermediate portion 5a and theend portions intermediate portion 5a. - The
panic lock 1 provides also an elastic pushingelement 11 pivoted on the case 2 and interacting with thefirst plate 10 to assist the end stroke positions of thebolt 3 to be reached. - In one preferred embodiment, the elastic pushing
element 11 is linear and has a stress axis that is coplanar with thefirst plate 10. - When the
bolt 3 is moved between its end stroke positions, the stress axis of the elastic pushingelement 11 oscillates from one side to the other of the straight line joining therotation fulcrums element 11 and of thefirst plate 10. - The stress axis of the elastic pushing
element 11 at the end stroke positions of thebolt 3 has substantially the same distance from therotation fulcrum 16 of thefirst plate 10. - The elastic pushing
element 11 comprises ahelical spring 17 and astem 18 engaged slidingly in adiameter hole 19 of arotation pin 20 defining also thefulcrum 15 of the pushingelement 11. - The
stem 18 has ahead 18a permanently engaged in aseat 21 provided on the perimeter edge of thefirst plate 10. - The
spring 17 winds around thestem 18 and is compressed between thehead 18a of thestem 18 and therotation pin 20. - The special arrangement and construction of the elastic pushing
element 11 enables a rotation force to be applied that is permanently coplanar with thefirst plate 10. - The
first plate 10 is thus not subjected to torsional stress that could, if present, alter the lying plane of thefirst plate 10 with consequent risk of malfunction of thepanic lock 1. - The elastic pushing
element 11, during rotation of thefirst plate 10 by thepawl 7 that engages with thefirst profile 12, is able to assist the action of thepawl 7. - Further, when the elastic pushing
element 11 reaches the position of thefirst plate 10 corresponding to the end stroke position of thebolt 3, the elastic pushingelement 11 is able to make thefirst plate 10 maintain the position reached to avoid movements of thebolt 3 that are not required. - In order to assist the disengagement of the
pawl 7 from the first shaped perimeter take-upprofile 12 of thefirst plate 10, thepanic lock 1 has aflexible organ 40 articulated on thesupport plate 4 of thebolt 3, which disengages thepawl 7 from theperimeter recess 12 of thefirst plate 10. - The
flexible organ 40 in particular is shaped as an "S"-shaped plate, having a pivot 40' pivoted in the hole 60 of thesupport plate 4 of thebolt 3, and atooth 40" engaging thepawl 7. - The
pawl 7, when it engages the first shaped perimeter take-upprofile 12 of thefirst plate 10, also engages and flexes theflexible organ 40. The elastic energy accumulated by the flexible element is then returned by theflexible organ 40 to thepawl 7 in the step of disengagement of thepawl 7 from the first shaped perimeter take-upprofile 12 of thefirst plate 10 so as to facilitate the detachment of thepawl 7 from the first shaped perimeter take-upprofile 12 of thefirst plate 10. - The basic mechanism illustrated until now is common to all the versions of the
panic lock 1. With reference tofigures 7a and7b , the version for a two-wing door or window provides with respect to the basic mechanism an additional component formed by anextraction plate 22 for extracting the drawingorgan 14 from thefirst end portion 5b of the slot 5. - The
extraction plate 22 has aprotrusion 23 for taking up the movement that is positionable in front of thebolt 3 and aslot 24 wherein the drawingorgan 14 is slidable. - The
extraction plate 22 is flat and is arranged parallel to thesupport plate 4 and on the side of thesupport plate 4 opposite the side facing thefirst plate 10. - The
extraction plate 22 is supported by thesupport plate 4 in a translatable manner in the same direction of translation as thesupport plate 4. - The
slot 24 of theextraction plate 22 has an intermediate portion 24a that is identical to theintermediate portion 5a of the slot 5 of thesupport plate 4, and afirst end portion 24b that is different from thefirst end portion 5b of the slot 5 of thesupport plate 4. - When the
protrusion 23 is in a position of front extraction from thebolt 3, thefirst end portion 5b of the slot 5 and thefirst end portion 24b of theslot 24 intersect, despite being partially staggered and the drawingorgan 14 is positioned through the zone of intersection between thefirst end portion 5b of the slot 5 and thefirst end portion 24b of theslot 24. - When the protrusion is on the
other hand 23 in the retracted position in thebolt 3, theintermediate portion 5a of the slot 5 and the intermediate portion 24a of theslot 24 are perfectly aligned and traversed by the drawingorgan 14. - If opening of the door is commanded by the panic device (which is not shown) present on the second wing, a suitable ejector present in this device, positioned at the
bolt 3, is pushed outwards to exert directly on the protrusion 23 a retraction force to retract thebolt 3 inside. - The selective translation of the
extraction plate 22 with respect to thesupport plate 4 produces the complete alignment between theintermediate portion 5a of the slot 5 and the intermediate portion 24a of theslot 24 that were originally partially staggered and, by virtue of the engagement of the wall of theslot 24 with the drawingorgan 14, an oscillation of thefirst plate 10 owing to which the drawingorgan 14, initially positioned in thefirst end portion 5b of the slot 5 and in thefirst end portion 24b of theslot 24, moves to theintermediate portion 5a of the slot 5 and to the intermediate portion 24a of theslot 24. - Once the drawing
organ 14 has been extracted from thefirst end portion 5b of the slot 5 and from thefirst end portion 24b of theslot 24, the ejector (which is not shown) continues its stroke, exerting the force of retraction directly on the front face of thebolt 3. - With reference to
figures 2a - 2b , the version ofpanic lock 1 with the function of recalling thelatch 6 by the key provides, with respect to the basic mechanism, an additional component formed by alongitudinal lever 25 for retracting thelatch 6 having a first end constrained on therotatable element 8 for driving thelatch 6 and a second end longitudinally opposite the first end having aperimeter profile 26 for taking up the movement from thepawl 7. - The
longitudinal lever 25 for retracting thelatch 6 is in turn formed by a flat plate parallel to thefirst plate 10 and positioned between the latter and one of theflat flanks longitudinal lever 25 for retracting thelatch 6 is more precisely pivoted on therotatable element 8 for driving thelatch 6 and has an oscillation angle limited for example by suitable interference surfaces. - The oscillation axis of the
longitudinal lever 25 for retracting thelatch 6 is parallel to the rotation axis of therotatable element 8 for driving thelatch 6. - In this version of the lock, the locking
peg 49 is used to make theinner rotor 27 and the outer rotor 27' constrained with therotatable element 8. - To summarize, when the
pawl 7 is driven by the key, in addition to engaging and rotating thefirst plate 10 that controls the retraction of thebolt 3, thepawl 7 engages and drives thelongitudinal lever 25, which in turn transmits movement to therotatable element 8, which lastly retracts thelatch 6. - With the function now disclosed, the
panic lock 1 is devoid of a grip for driving the latch from the outer side of the door or window. - With reference to
figures 3a - 3c ,4a - 4c ,5a - 5b , the version ofpanic lock 1 with the function of enabling or disabling the grip that operates on the outer side of the door or window provides, with respect to the basic mechanism, also atransmission lever 28 interacting with the movement receiver and distributor for switching between a connection state and a disconnection state of the outer rotor 27' from therotatable element 8 for driving thelatch 6. - In this version of the lock, the locking
screw 48 is used that fixes the soleinner rotor 27 to therotatable element 8 for driving thelatch 6. - The
transmission lever 28 is pivoted by arotation pin 50 on therotatable element 8 for driving thelatch 6 and is normally retained by an elastic element 29 in the disconnection state. - The
transmission lever 28 comprises in particular two identical curvedflat bars rotatable element 8 for driving thelatch 6 is interposed in the direction of the thickness. - The end 28' of the
transmission lever 28 longitudinally opposite thetransmission lever 28 pivoted on therotatable element 8 for driving thelatch 6, through the effect of the state switch of thetransmission lever 28, moves between a position of interference and a position of non-interference with the trajectory of anengagement seat 51 provided on the outer rotor 27'. - Only when the
transmission lever 28 engages therelative seat 51 is the outer rotor 27', in the rotation stroke, able to rotate therotatable element 8 in a solidly constrained manner to drive thelatch 6. - The angular positions of the
transmission lever 28, to which the connection state and the disconnection state correspond, are identified precisely by suitable end strokes of therotation lever 28. - More precisely, the end rotation strokes are formed by a
first pin 52 and asecond pin 53 fixed to thetransmission lever 28 and adapted to interacting with stop surfaces 54, 55 obtained perimeterally on therotatable element 8 for driving thelatch 6. - The elastic element 29, in the illustrated solution, is a helical spring retained in a state of axial compression between the second
end stroke pin 53 and the bottom of aslit 56 that opens on the perimeter of therotatable element 8 for driving thelatch 6. - Advantageously, in these lock versions the movement distributor and receiver also comprises a rotatable
second plate transmission lever 28 to switch the state thereof. - The
second plate cam transmission lever 28. - The
second plate first plate 10. - Moreover, the
second plate first plate 10. - The
second plate first plate 10 contrastingly and through the action of anelastic element - The
second plate bar 28a facing the side of therotatable element 8 for driving thelatch 6 where theinner rotor 27 is positioned. - With specific reference to
figures 3a - 3c , thepanic lock 1 automatically enables and disables the grip that operates on the outer side of the door or window. - In practice, the grip that operates on the outer side of the door or window is automatically disabled by the extraction movement of the
bolt 3 and enabled by the retraction movement of thebolt 3. - Starting from the condition illustrated in
figure 3b wherein thebolt 3 is ejected and thetransmission lever 28 is in the disconnected position, when the user inserts the key into the cylinder of the lock and rotates the key by a complete turn in the direction that is necessary to retract thebolt 3, thepawl 7 engages thefirst plate 10 and rotates the first plate 10 (anticlockwise infigure 3b ) to command the retraction of thebolt 3, thefirst plate 10 in turn rotating in the same direction thesecond plate 30 and thecam 31 of thesecond plate 30 rotates thetransmission lever 28 until the alignment of the end 28' of the latter on therelative engagement seat 51 is brought about. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is actually transmitted to therotatable element 8 for driving thelatch 6. When the user again inserts the key into the cylinder of the lock and rotates the key by a complete turn in the opposite direction that is necessary to extract thebolt 3, thepawl 7 engages thefirst plate 10 and rotates the first plate 10 (clockwise infigure 3c ) to command the extraction of thebolt 3, thefirst plate 30 in turn rotating in the same direction thesecond plate 30 and thecam 31 of thesecond plate 30 rotates in the opposite direction to the previous direction thetransmission lever 28 until the disengagement of thesecond plate 30 from therelative engagement seat 51 is brought about. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is not transmitted to therotatable element 8 for driving thelatch 6. - With specific reference to
figures 4a - 4c ,e 5a - 5b thepanic lock 1 provides the voluntary enabling and disabling of the grip that operates on the outer side of the door or window. - The
second plate 30', 30" has aperimeter profile 33', 33" for taking up the movement directly from thepawl 7. - The
plate 30', 30" rotates selectively with respect to thefirst plate 10. - The maximum permitted size of this selective rotation of the
second plate 30', 30" with respect to thefirst plate 10 is defined by the length of aslot 58', 58" in the form of an arc having the centre on the common rotation axis of thefirst plate 10 and of thesecond plate 30', 30" wherein astop 57 is slidable. - In the specific case, the
stop 57 is formed by a pin fixed to thefirst plate 10 and theslot 58', 58" is formed on thesecond plate 30', 30" or vice versa. - The
panic lock 1 illustrated infigure 4a - 4c provides the voluntary enabling and disabling of the grip that operates on the outer side of the door or window by rotation by a complete turn of the key in the cylinder of the lock. - Starting from the condition in which the
bolt 3 is already in the retracted position and thetransmission lever 28 is in the disconnected position, when the user inserts the key into the cylinder of the lock and rotates the key by a complete turn in the same direction that is necessary to retract thebolt 3, thepawl 7 does not engage thefirst plate 10 but only the second plate 30', which can rotate selectively with respect to thefirst plate 10, which remains stationary. The cam 31' of the second plate 30' rotates thetransmission lever 28 until the alignment of the end 28' of the latter relative to theengagement seat 51 is brought about. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is actually transmitted to therotatable element 8 for driving thelatch 6. When the user again inserts the key into the cylinder of the lock and rotates the lock by a complete turn in the opposite direction that is necessary to extract thebolt 3, thepawl 7 engages the second plate 30' and rotates it in the opposite direction to the preceding direction, and the cam 31' of the second plate 30' rotates thetransmission lever 28 in the opposite direction to the preceding direction until the disengagement of the second plate 30' from therelative engagement seat 51 is brought about. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is not transmitted to therotatable element 8 for driving thelatch 6. - The
panic lock 1 illustrated infigures 5a - 5b provides the voluntary enabling and disabling of the grip that operates on the outer side of the door or window by rotation of less than a complete turn of the key in the cylinder of the lock to prevent the extraction of the key when the grip that operates on the outer side of the door or window is enabled. - The main difference with respect to the previously disclosed version of panic lock consists of limiting the maximum angle of rotation permitted to the
plate 30" with respect to thefirst plate 10. Theplate 30" has the same conformation as plate 30' and theslot 58" is less long than the slot 58'. - Starting from the condition in which the
bolt 3 is already in the retracted position and thetransmission lever 28 is in the disconnected position, when the user inserts the key into the cylinder of the lock and rotates the lock by a partial turn in the direction necessary to retract thebolt 3, thepawl 7 does not engage thefirst plate 10 but only thesecond plate 30", which can rotate selectively with respect to thefirst plate 10, which remains stationary. At the end of a rotation that is more limited than in the previously illustrated case, thecam 31" of thesecond plate 30" nevertheless rotates thetransmission lever 28 until the alignment of the end 28' of the latter relative to theengagement seat 51 is brought about. At this point, if the user rotates the outer grip, the command from the outer rotor 27' is actually transmitted to therotatable element 8 for driving thelatch 6. In this condition, the key remains imprisoned in the cylinder of the lock. When the user rotates the key by a partial turn in the opposite direction that is necessary to extract thebolt 3, thepawl 7 engages thesecond plate 30" and rotates thesecond plate 30" in the direction opposite the preceding direction, and thecam 31" of thesecond plate 30" rotates thetransmission lever 28 in the opposite direction to the preceding direction until the disengagement thereof from therelative engagement seat 51 is brought about. At this point, the key is free and can be extracted from the cylinder of the lock and if the user rotates the outer grip, the command from the outer rotor 27' is not transmitted to therotatable element 8 for driving thelatch 6. - Obviously, the versions of panic lock illustrated in
figures 4a - 4c , and5a - 5b must provide structural features and mechanical properties, in particular stiffness for thesprings second plate 30', 30" with respect to thefirst plate 10. Naturally, several functions that are compatible with one another amongst those disclosed can be implemented modularly in the same panic lock. - For example, the version of panic lock for a two-wing door or window is compatible with all the other functions disclosed above.
- The panic lock as conceived herein is susceptible to many modifications and variations, all falling within the scope of the invention as defined by the appended claims; furthermore, all the details are replaceable by technically equivalent elements.
- In practice, the materials used, as well as the dimensions, can be any according to the needs and the state of the art.
