Un verrou de sécurité permet de bloquer le mécanisme.In this system, the panic bar (8) is mounted on a strip (7) removably adaptable on a flange in which the return mechanism for controlling the bolt (s) (25) is housed. This flange may, for a system intended for a glass door, be part of a belt (4) enclosing the door for fixing on it without drilling or cutting. The bolt control rods are housed in profiles (14) retained in this flange or this strip and in bolt boxes (15). The upper bolt (25) is associated with a retaining device in the erasing position, which is unlocked automatically when the door is closed. A security lock makes it possible to block the mechanism.

Description

Anti-panic opening system.

The present invention relates generally to sys¬ tems called panic systems.

These systems are in common use in all premises, such as shops, offices, warehouses, workshops, etc. in which it is necessary to have a closure normally opposing access to the room from the outside while allowing the occupants of this room to open the door or doors equipped with such a system by a simple push or pressure, to be able to quickly leave said room in the event of an accident, especially fire, declaring itself therein.

It is known, in such systems, to provide an actuating element, known as an anti-panic bar, which when a push or pressure is exerted on it causes by mechanical deflection, the erasure of one or two bolts such as an upper bolt and a lower bolt, which then allows the door to be opened freely or similar to the outside of the room. It is also known, in certain systems, to provide an element ensuring the blocking of the panic bar in its open position after it has been pushed in or moved, which then allows free operation of the door while maintaining the bolts in a condition of erasure.

WIPO An object of the invention is to provide an anti-panic opening system that can be adapted if desired on a glass door, without having to drill or similar operations on this glass.

Another object of the invention are to create a system of the general type ouver¬ ture panic previously mentioned, arranged to allow, after the opening of the door fitted with a ^'such a system, an automatic reset of the bolt (s) in their strike when this door is closed, to take a deadbolt condition.

Yet another object of the invention is to create an anti-panic opening system of the general type mentioned previously, arranged so as to allow the system to be locked in a way that opposes opening the door itself. using the panic bar, ^' by providing a security closure, for example during the night, when the room equipped with said system is not occupied, which is against unauthorized opening of the door by a person who may have broken into the premises, for example by breaking and entering.

The invention is embodied in an anti-panic opening system of the type comprising a panic bar which can be actuated by push or by pressure and connected by return members to at least one bolt engaged in a keeper, in order to cause during from this push or this pressure an erasure of this bolt to allow the opening of the door, adaptable more especially to glass doors, characterized in that it comprises at least one flange which can be adapted on the face of the door having to receive the panic bar, means forming a belt enclosing the door panel for fixing this flange on this door, the return members of the panic system being housed in said flange, and an adaptable strip removable this flange and carrying the panic bar, an actuating element provided in a known manner in this bar being, during assembly brought into engagement with these return members. Preferably, a flange and a strip are provided on each side of the door.

The transmission elements extending between the return members and the bolt or bolts are then suitably housed in profiles forming covers, preferably connected to the flange and to the bolt housing.

According to another particular feature, the invention relates to an anti-panic opening system of the aforementioned type, characterized in that it is provided on the door, in the vicinity of the bolt, a retaining element automatically engaging with this bolt when it reaches its erasing position at the time of actuation of the panic bar, to maintain said bolt in its erasing position, and an actuating element functionally associated with this retaining element and intended to cooperate with the frame of the door or the like when this door closes, to actuate said retaining element and to release the bolt in order to allow its return to a dead bolt condition,

In this way, when the anti-panic system has been activated by a push or pressure exerted on the anti-panic bar, the latch is retained in the erasing position until the door is closed, so that, on the one hand, it does not hinder the movement of this door during its opening and, on the other hand, it ensures an automatic locking on closing, then resuming a deadbolt condition.

According to an advantageous embodiment, there is provided a bolt both at the top and at the bottom of the door, and the return members actuated by the panic bar are connected to these two bolts.

According to a possible embodiment, the retaining element is formed by a hook-shaped piece which can engage

OMH by its beak in a notch or the like of the bolt when the latter reaches its erasing position, and which cooperates functionally with an actuating tab elastically urged towards a projecting position in which it is spaced from the retaining element , but which can coo¬ operate by this projecting part with the frame of the door in order to be brought into a condition of actuation of the retaining element for its erasure, in a manner releasing the bolt.

According to another particular feature, a lock is provided in combination with the return members housed in the flange, one element of which comes, when it is actuated, in engagement with one of the return members, to immobilize them in the condition closing the door, which prevents any unauthorized opening of the latter from inside the room when it is not normally -'occup-ê, for example during the night.

According to a possible embodiment, there is provided in the flange a pivoting part whose angular displacement is controlled during the actuation of the panic bar and which is engaged with a tilting lever connected to an actuating rod of the locking system bolt. In this case, the lock can, for locking the door, be brought into a support position against the pivo¬ aunt piece, or the lever, in a manner opposing. its movement.

When a bolt is provided at the top and bottom of the door, the pivoting part may for example have an S shape, this part being pivotally mounted in the flange by its central part and being connected by its ends to two levers tilting actuating rods connected to the bolts.

It will be understood that, if the anti-panic closing system according to the invent.ion is intended to be mounted on doors in wood or on metal joinery, the flange for receiving the return members and supporting the strip with the panic bar can be fixed on the door or carpentry for example by screwing, instead of using a belt of the type used for a glass door.

The description which follows, made with reference to the appended drawings given without limitation, will allow a better understanding of the invention.

Figure 1 is a perspective view of a glass door on which is adapted the panic system according to one invention;

Figure 2 is a field view of the door, looking along line II-II in Figure 1;

Figure 3 is an enlarged sectional view, on the line III-1II in Figure 1;

Figure 4 is a view taken looking along line IV-IV in Figure 3, showing the return mechanism.

Figures 5 and 6 are two large-scale views showing the upper bolt of the door in two different positions.

The glass door 1, shown in Figure 1, is of a well known type, which can be mounted in a metal frame or the like, or else. in a dormant part also in ice, as shown in 2 in FIG. 2. The parts reported on the door and serving as hinges are indicated in 3 in FIG.

According to the embodiment considered, a strip belt 4 (FIG. 1) surrounds the door at the required height, in order to allow the mounting of the panic system without having to provide in the glass door with holes or ^ eg ^ J & iSeξ This belt forms, on each face of the door 1, a flange 5 (FIG. 3), the upper and lower wings 6 of which constitute slides for receiving and holding a strip 7 in place. One of the strips 7 carries, as shown in the drawings, a panic bar designated as a whole by the reference 8 and which may be of known type. There are many types of panic bars and it will be understood that they can adapt as desired on the belt and headband system provided according to the invention. This belt is completed, at each end of the strips 7, by end pieces 9 (Figure 2) which can be retained in place by screwing.

The return mechanism provided according to the invention for controlling the upper and lower bolts of the door is generally designated by the reference 10 in FIG. 4. It is housed in a support 11 which has been shown in FIG. 3 and which is arranged in the flange 5, 6 of the belt directed towards the panic bar 8.

This deflection mechanism 10 is intended for the control of two rods 12, 13 which extend on the corresponding face of the glass door 1, inside profiles forming covers 14. These profiles are retained towards their ends, d on the one hand by the belt, for engagement for example in cutouts of the wings 6 of the flanges 5, and secondly in recessed bolts 15, 16 whose fastening to the door ice pe ^'ut occur without drilling the latter by fitting onto the upper and lower edges of this door as shown in FIG. 2.

The deflection mechanism 10 comprises an S-shaped part 17, pivotally mounted about an axis 18 and the pivo¬ tement of which is controlled during 1 "actuation of the panic bar 8 in a conventional manner The ends of the branches of the part 17 are engaged in notches of two small deflection levers 19 pivotally mounted on the

OM? I support 11 around axes 20. A point of each lever 19 is connected by a piece in the form of an angled link 21 to the corresponding rod 12, 13.

It can be seen in FIG. 4 that the lower link 21 provides a flat area 22 against which the arm 23 of a lock 24 can be applied, for a reason which will be indicated below.

We will now refer to Figures 5 and 6. We see that the upper bolt 25 of the door is slidably mounted in a guide 26 provided in the housing 15. This bolt has a notch 27 with which can cooperate, through a light 28 of the guide 26, a blocking element or latch 29 in the form of a hook which can tilt around an axis 30. A floating tab 31 is slidably mounted in the vertical direction in the housing 15, by engagement of an axis 32 in a slot 33 of this housing 15. This tab 31 is connected by a tension spring 34 to the fixed guide 26, so as to be constantly stressed upwards. The lower part of the lug 31 can cooperate as shown in FIG. 6 with the latch 29 to make it tilt clockwise, its beak then moving away from the notch 27 of the bolt 25, while this latch tends normally coming to occupy a position as shown in Figure 5, in which this beak is engaged in this notch 27 of the bolt.

The operation of the panic system is as follows

When the panic bar 8 is actuated, the device of this bar, of a type known per se, causes the part 17 to pivot in the anti-clockwise direction around the axis 18, so that the branches of this piece tilt the levers 19 around their pivots 20 to cause, by means of the rods 12, 13 the erasure of the upper 25 and lower 35 bolts, which thus allows the door to be opened by pushing, in the direction of outside, from per se required for panic systems.

When the door opens, the tab 31, which was retained in a lower position by abutment against the frame of the door, is released, and under the effect of the spring 34 it moves upwards to come occupy the position visi ¬ ble in Figure 5. During this movement, it releases the lock 29, which can thus tilt counterclockwise around the axis 30, so that its beak engages through the light 28 of the guide 26 in the notch 27 of the bolt .25, which in the erasing position of this bolt has come to be placed opposite this light as visible in FIG. 5. The condition obtained is that visible in FIG. 5, so that the panic system is kept in an open position as long as the door remains open. The locking of the bolt 25 in the erasing position is in fact transmitted by the rod 12 to the mechanism housed in the flange of the belt and thus also retains the lower bolt 35 in the erased position.

As shown in FIG. 2, there is provided on the door frame, at the upper part thereof, a ramp-shaped guide 36.

When the door is closed, the upper end of the lug 31 is pushed down by this ramp. 36, and its lower end acts on the tail of the latch 29 to cause it to tilt clockwise as shown in FIG. 6 , so that its beak is released from the notch 27 of the bolt 25, this bolt is thus released and with it the entire mechanism, so that under the effect of the usual return spring of the anti-bar panic the bolts come back on again in the combined strikes, the upper bolt then again constituting a dead bolt.

It will be noted that if the panic bar is equipped in a manner known per se, with a locking device in

WIPO open position, this device can be controlled to assu¬ rer this locking in the open position without interference with the elements described above.

As indicated above, a lock 24 is provided according to the invention, the arm 23 of which can be brought into an application position against the lower lever 21, as visible in FIG. 4. In this condition the anti bar ¬ panic can no longer be operated to control the opening of the door, since the return mechanism is. Locked in the closed position. This provides security, for example at night, when no one should normally be in the room equipped with the panic system. Under these conditions, even a person breaking into this room cannot operate the anti-panic system from inside the room, for example to allow accomplices to access it from the outside.

Thus, the system according to the invention allows, in addition to a function in itself conventional of a panic bar, the retention of the system in the open position by locking the upper bolt when the door has been opened, as well as an automatic return to a deadbolt condition as soon as the door closes, and a locking of the whole system in safety closing condition.

Modifications can be made to the embodiment described, in the field of technical equivalences, without departing from the invention.
