Description

The present invention relates to an anti-panic lock with a safety barrel and more particularly to an anti-panic lock of the type which are mounted on doors intended to be quickly opened from the inside by simple actuation by an operator of a commanding bar. the movement of the bolt of said lock in the keeper with which it is associated. Such panic locks are generally used on exit doors, and in particular in emergency exits, public places (cinemas, theaters, etc.) or others, which must be able to be evacuated quickly, without being, however, free access from the outside. It appeared, however, that it was necessary to provide such locks, operating cylinders making it possible, using keys, to control the doors provided with these locks from the outside.

There are conventionally two types of barrels, some being generally qualified as "cylindrical" barrels, and being such that their stator has substantially a cross section whose outline rests on all or part of a circle centered on the 'axis of said barrel, the others being generally qualified as "profiled" barrels, and being such that their stator is constituted by a cylindrical main body surmounted, in one of its lengths, by a substantially parallelepipedic secondary body. Because of their difference in shape, it corresponded, until now, to each of these two types of barrel, a type of panic lock which was more particularly adapted to receive a barrel of this type and allow it to cooperate with the elements of the lock controlling the opening or closing movement of the bolt. Therefore, it was necessary, to be able to meet the demands of users and their choice of barrel, to produce and keep in stock simultaneously, both panic locks adapted to cylindrical barrels and panic locks adapted to profiled barrels.

The present invention provides, for its part, panic locks on which it is possible to adapt both cylindrical barrels as profiled barrels, such locks, comprising, in particular, housings for the two types of barrel as well as elements which can cooperate with the bits of the two types of barrel to actuate the bolt of the lock. In addition, the invention also provides panic locks with a barrel and a side bolt, the bolt control unit of which is just as suitable for doors opening on the right as for doors opening on the left.

The present invention therefore relates to an anti-panic lock with safety barrel intended to be mounted on a door and comprising at least one bolt admitting two positions, one authorizing the opening of the door, the other being a closed position where said bolt can be engaged in a keeper, this lock comprising, in addition, an actuating bar pivotally connected to said door, at each of its ends, by an assembly formed by a housing fixed on said door and an integral lever towards one of its ends of the actuating bar and pivotally mounted, at its other end, in said housing, at least one lever being a control lever cooperating with elements of its housing to actuate the bolt during the angular displacement of said actuating bar, the actuating bar and the levers being intended to be pivoted in a first direction for controlling the opening of the door, the control lever housing being associated with at least one safety barrel comprising a stator inside which pivots a rotor driving a bit cooperating with maneuvering means to actuate the bolt, this lock being characterized in that said housing comprises at least two separate operating means which can each cooperate separately with a barrel to actuate said bolt.

Advantageously, the housing of the control lever comprises maneuvering means intended to cooperate with the bit of a cylindrical barrel and maneuvering means intended to cooperate with the bit of a profiled barrel. The control lever housing can comprise at least two barrel housings, one being intended to be traversed by a part secured to the rotor of a cylindrical safety barrel, the other being intended to be traversed by a portion secured to the rotor of a profiled safety cylinder. The bolt can be a lateral bolt pivoting about an axis inside the casing of the control lever, between its open position and its closed position where it is released relative to the casing, the aforesaid operating means comprising , on the bolt, at least one bearing surface intended to cooperate with the bit of a cylindrical barrel and at least one bearing surface intended to cooperate with the bit of a profiled barrel. Such a lock can also be used with a high bolt and / or a low bolt, of the type, for example, of those described in the patent application in the name of the applicant, published under the number FR-A-2 60̸9 492 without departing from the scope of the invention.

Preferably, the bolt has a plane of symmetry perpendicular to its pivot axis. The bearing surface of the bit of the cylindrical barrel may be an arcuate surface having for plane of symmetry the plane of symmetry of the bolt, said bolt further comprising two bearing surfaces distributed on either side of said arcuate surface and intended to cooperate with the bit of a profiled barrel.

Advantageously, the actuating bar and the levers are reversible and can be pivoted in a second direction to control the opening of the door, the control lever housing comprising at least two housings each intended to receive a profiled barrel. , a barrel in a first of these two housings cooperating with the means for maneuvering the bolt to actuate the latter when the actuating bar and the levers controlling the opening of the door by pivoting in the first direction, a barrel in the second of these two housings actuating the bolt when the actuation bar and the levers control the opening of the door by pivoting in a second direction.

In other embodiments, the actuation bar and the levers are reversible, the control lever housing comprising only a housing for cylindrical barrel and a housing for profiled barrel, the barrel of the first housing actuating the bolt in any direction for controlling the actuation bar and levers.

Preferably, the axis of a barrel is substantially perpendicular to the pivot axis of the bolt. The control unit can include a bottom intended to be fixed on a door, a barrel passing through said bottom so that its bit is inside said case. Two housings for profiled barrel can be distributed symmetrically with respect to the plane of symmetry of the bolt. The cylindrical barrel can be a barrel with an eccentric rotor. The rotor key slot can be horizontal when the lock is in position on a door and the rotor is at rest.

In an advantageous embodiment, the control lever housing has at its bottom at least one housing intended to receive a cylindrical barrel and at least one housing intended to receive a profiled barrel.

In another advantageous embodiment, the bit associated with the cylindrical barrel is driven in movement by an intermediate piece linked to the rotor. The intermediate piece may be a gear wheel passing through the housing in a recess at one of the walls thereof, the toothing of said wheel cooperating with a toothing which is provided with the bit, said bit being pivotally mounted on the bottom of said housing.

We will now describe, purely by way of non-limiting illustration, an embodiment of an antipanic cylinder lock, in accordance with the invention, this description having to be read with reference to the appended drawings.

We see in Figures 1 to 4 that an anti-panic lock according to a first embodiment of the invention comprises, in a conventional manner, an actuating bar (not shown) secured at each of its ends, levers mounted pivoting around the same axis, in boxes intended to be fixed by their bottom on a plate P of the door on which said panic lock must be mounted. One of these levers is an operating lever 2 cooperating with elements of the housing 1 with which it is associated to actuate the bolt 3 of said lock between its open position and its closed position.

There is shown in Figures 1 to 3, the housing 1 associated with the operating lever 2 controlling the movement of a lateral bolt 3 pivotally mounted in said housing.

The housing 1 has a rectangular bottom 4 bordered, on its lateral lengths, by two walls 5 a and 5 b facing each other and perpendicular to said bottom 4. These walls 5 a and 5 b are identical and have the shape of a rectangle, the length of which is the length of the bottom, this rectangle being surmounted by an isosceles trapezoid whose main base is that of the lateral lengths of said rectangle which is the furthest from said bottom 4. The plane perpendicular to the bottom 4 passing by the median width of the housing 1 is a plane of symmetry for the bottom 4 and for said walls 5 a and 5 b . The lever 2 is a substantially rectangular elongated blade comprising at one of its ends a sleeve into which the actuating bar (not shown) of said panic lock. This lever 2 is articulated towards its other end around a pivot axis 6 which is a rod passing through the housing 1 extending perpendicularly between the two walls 5 a and 5 b , substantially between their trapezoidal parts, at said plane of symmetry of said walls. The lever 2 is parallel to the walls 5 a and 5 b and is adjacent to the wall 5 a , which is the one of the two walls which is closest to the other housing of the lock. Its opposite end to the actuating bar has the shape, beyond the pivot rod 6, substantially of a triangle whose tip is rounded. At this end, is arranged, projecting from said lever 2, on the side of said lever 2 which is furthest from the wall 5 a , a cylindrical pin 7, of axis perpendicular to the plane of said lever 2 embedded in said lever 2, and the length of which, outside said lever 2, corresponds substantially to the thickness of said lever 2.

The bolt 3 is mounted, centered with respect to the plane of symmetry of the walls of the housing, in pivoting on a rod 8 adjacent to the wall 5 b , parallel to the length of the housing 1 and disposed relative to the axis of the rod 6 pivoting lever 2, at a distance less than the distance between the axes of the rod 6 and the pin 7. The bolt 3 has substantially a main shape defined by two side walls 3 a and 3 b parallel to the plane of symmetry of the walls of the housing 1 and interconnected by a main body whose surface is parallel to the axis of the rod 8, the cross section of this main body being substantially a triangle, one of the sides of which is an arc of circle centered or not on the 'axis of the rod 8. A wall 3 c , formed by a portion of cylindrical surface centered on the rod 8 corresponds to these sides in an arc. Said rod 8 crosses said main shape towards its edge opposite the wall 3 c . The bolt 3 crosses the wall 5 b so that one of its edges limiting its cylindrical wall 3 c is located outside the housing 1, the other being inside said housing 1. The wall of the bolt located inside the housing 1 is referenced by 3 d , the wall located, at least partially, outside the housing 1 being referenced by 3 e .

This bolt 3 further comprises a straight parallelepiped recess 9 crossed by the rod 8 and opening on the wall 3 rd near its edge which is opposite to the arched wall 3 c , the bottom of this recess being parallel or not to the wall 3 e . In this recess 9, crossed by the rod 8, is journalled, on the rod 8, a spring 10̸ terminated by two branches 11, a branch 11 bearing on the bottom of the recess 9, the other branch 11 s' pressing on the wall 5 b .

The bolt 3 is, moreover, extended substantially at its pivot axis, beyond its wall 3 d and towards the outside of the bolt 3, by a span 12 comprising two branches 12 a and 12 b extending respectively on either side of the walls 3 a and 3 b of said bolt 3, and connected together by a portion 12 c of convex shape, each of these two branches being associated, on its part opposite the bottom 4 with a notch , respectively referenced by 13 a and 13 b , intended to cooperate with the pin 7 according to the angular position of the lever 2 relative to the housing, the convex shape of the zone 12 c allowing the pivot of the pin 7 between these two notches 13 a and 13 b . The wall 3 d of said bolt 3, moreover, is extended beyond the wall 3 c by a bearing wall 14 curved according to an arc of curve whose concavity is directed towards the wall 5 b and whose axis is perpendicular to the plane of the bottom 4 and in the plane of symmetry of the bolt 3. The edge of this wall 14 located radially outside with respect to the rod 8 is arranged to allow the rotation of the bolt 3, around the rod 8, towards the inside of the housing 1.

Each of the walls 3 a and 3 b is associated with an ear housing, referenced respectively by 15 a and 15 b , which is a recess formed in a parallelepipedic body secured by one of its faces to one of the walls 3 a or 3 b , this recess being open towards the outside of the bolt 3 and being delimited by three rectangular and perpendicular walls, one of which is parallel to the wall 3 d , another is parallel to the walls 3 a and 3 b , the last being that of the walls of said recess which is closest to the axis of the rod 8. The housings 15 a or 15 b thus defined are located substantially at the level of the bearing surface 14, and are separated from said bearing surface 14 by a extension 16 a or 16 b of its wall which is parallel to the walls 3 a and 3 b .

On the bottom 4 are cut three housings 17 a , 17 b , 18 for barrel, two of these housings 17 a , 17 b being housings for profiled barrel, distributed on each side of the bolt 3, symmetrically with respect to the plane of symmetry of the latter, the third of these housings being a housing 18 for cylindrical barrel. These housings 17 a , 17 b and 18 have a cross section corresponding to the cross section of the barrel with which they are associated, the part of the housings 17 a and 17 b intended to receive the parallelepipedal secondary body of a profiled barrel being further from the bolt 3 as their part intended to receive the main body of said barrel.

There is shown in Figures 1 and 2, a profiled barrel 19 in position in the recess 17 b , the bit 21 of said barrel 19 projecting inside the housing 1 relative to the wall cylindrical of this barrel 19 and being intended to cooperate with the ear housing 15 b and to come to bear on the wall of said housing 15 b , which is perpendicular to the extension 16 b , to tilt the bolt 3. It is also possible to have a profiled barrel in the housing 17 a , its bit then cooperating with the ear housing 15 a .

In the cylindrical housing 18 is mounted a cylindrical barrel 20̸ with eccentric or centered rotor, the bit 23 of which is constituted by a flat piece linked to the rotor, which pivots on the axis of the rotor and on which is disposed an eccentric pin 22 on the surface 14 and intended to cooperate with said surface to rotate the bolt 3. The slot in the rotor key is intended to be horizontal, in the rest position of the rotor, when the assembly is mounted on a door, c that is to say perpendicular to the walls 5a and 5b of the housing 1, the rotor part of said barrel 20 being substantially in the axis of casing 1.

In other embodiments, not shown, the housing could have only one housing for a profiled barrel disposed on one side or the other of the bolt, the bolt 3 described above being equally suitable for each of the two sides. In other embodiments, again, the housing could have only two housings for profiled barrel and not have housing for cylindrical barrel.

To use a housing-lever assembly as shown in the figures, one chooses, firstly, the direction in which one wishes to operate the lever 2 of said housing 1, that is to say that of the two dihedrons delimited by the bottom 4 of the housing 1 and the plane perpendicular to said bottom 4 passing through the axis 6, in which it is desired that said lever 2 and the actuating bar are located relative to the plane from the bottom of the housing 1. This being done, it is possible to actuate the bolt 3 by acting on the actuating bar to pivot the lever 2 on its axis 6, according to an angular displacement during which the pin 7 cooperates with one of the notches 13 a or 13 b of the bearing 12 to lift the latter relative to the bottom 4 and tilt the bolt 3 on itself in order to move it into its open position, such a mechanism making it possible to open a door from the inside. When the operator releases his action on the actuating bar, the bolt 3 automatically resumes its closed position, under the action of the branches 11 of the spring 10̸ journalled inside the housing 9.

In addition, when such a case is mounted on a door, it is possible to associate it with a cylindrical barrel 20̸ or with a profiled barrel 19. If one chooses to associate it with a profiled barrel, one will have that preferably, in that of the two housings 17 a or 17 b which is on the side opposite the triangular end of the lever 2, relative to the plane of symmetry of the bolt 3. Once the assembly is in place, it is possible to act on the bolt 3, from the outside by inserting the key, associated with the barrel that has been chosen, in the rotor thereof and by rotating the latter in its stator, which has for effect, for a cylindrical barrel, to push back the bearing surface 14 using the bit 23 and the pin 22 and for a profiled barrel, to push back one of the bearing ears 15 a or 15 b using of the bit 21 of this barrel. This causes the latch 3 to tilt inside the housing 1, which disengages said latch 3 from the keeper with which it was associated, and frees the pivoting of the door on itself.

Box 1, provided with housings 17 a , 17 b is reversible and can be mounted either on a door type "right" or type "left", thanks to a suitable orientation of the housing 1 for mounting and positioning of the profiled barrel in that of the housings 17 a , 17 b which is appropriate for the case envisaged.

There is shown in Figures 5 and 6 a second embodiment of the invention for which we have used, for the elements of this second embodiment, which are found in the first embodiment, the same reference number increased by one hundred .

This panic lock comprises, in the same way, an actuating bar mounted on levers articulated in housings fixed on a plate, referenced by P, of the door. One of these levers, referenced by 10̸2 and mounted in a housing 10̸1, is an operating lever pivotally actuating the bolt 10̸3 of the lock. On the bottom 10̸4 of the housing 10̸1 are provided two recesses 117 a and 117 b for profiled cylinder.

This housing 10̸1 is also associated with a cylindrical barrel 120̸ whose rotor is not mounted on the bottom 10̸4 of said housing 10̸1, but passes through the plate P next to it, the stator of said barrel extending on the side of said plate P opposite said housing 10̸1. On the other side of said plate P is mounted on the end of the rotor a gear wheel 150̸ which is a flat disc the edge of which has a transmission toothing 153, this wheel 150̸ being centered on the axis of said rotor and passing substantially through its teeth, through a recess 152, that of the walls of the control unit 10̸1, which is closest to the other housing of the lock. On the bottom 10̸4 of the control box 10̸1 is pivotally mounted a flat part 151, which is a bit a part of which is a portion of a gear wheel whose toothing 154 is intended to cooperate in pivoting with the toothing 153 of the wheel 150̸, this part being extended by an elongated part provided with a pin 122 extending perpendicular to the bottom 10̸4 from housing 10̸1. This pin 122 is intended to cooperate with the support wall of the bolt 10̸3 associated with said control box 10̸1 to tilt said bolt 10̸3, this bolt 10̸3 being substantially identical to the bolt 3 which has been previously described. Thus, with a device according to this variant, it is possible to move the cylindrical barrel away from the edge of the door, which is not the case with a device according to a first embodiment described, the bottom of the control unit generally disposed just next to said edge. The pivoting of the bit 151 is here obtained thanks to an intermediate piece between said bit 151 and said rotor, the symmetry of the means for operating the bolt relative to the median plane of said bolt being preserved.
