• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.

• 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.
• a strip belt 4 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 & iSe ⁇
• 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.
