Abstract

The present addition to the main patent consists of a device which automatically imparts to the hook 4 of the main invention a blocking in this open position and which can be released manually after the opening of the door. This addition also adds an automatic alarm and display system which is seen from outside the protected space, as soon as the system, by obeying the programmer, has changed to the lock-releasing position.

Description

lére ADDITION
-t-s-:-:-
au SYS?SME et APPAREILLAGE AN HOLD-UP inversant
le résultat de la menace de mort par braquage d'arme
Dans le brevet principal le pène n'était libéré que pendant l'action du temporisateur, que celle-ci s'exerçat soit mécaniquemment soit électriquement et le maintien dans cette position nécessitait donc celui de la force motrice qui la conditionait.En outre rien ne signalait extérieurement à l'est pace clos que le système s'était mis dans la position d'ouverture
La présente addition compléte l'invention principale en ce qu un crochet secondaire vient s'encastrer dans le crochet principal pour n'8re libéré seulement que lorsque une personne en ayant décidé et ayant par les moyens normaux classiques de la serrure ouvert la porte , trouvera à l'intérieur de l'espace clos la tirette , le poussoir, la glissière ou le bouton qui est le prolongement exterieur au système d'accro- chage et qui lui permettra de libérer le crochet principal remettant ainsi l'ensemble sous la dépendance du programmateur pour la nouvelle période qu'elle aura programmée.1st ADDITION

at the SYS? SME and reversing HOLD-AN APPARATUS
the result of the threat of death by robbery of a weapon
In the main patent the bolt was only released during the action of the timer, whether it was exercised either mechanically or electrically and maintaining in this position therefore required that of the driving force which conditioned it. externally signaled east closed space that the system had moved to the open position
The present addition completes the main invention in that a secondary hook comes to be embedded in the main hook so as to be released only when a person having decided and having by the normal normal means of the lock open the door, will find inside the confined space, the pull tab, the push-button, the slide or the button which is the extension outside the hanging system and which will allow it to release the main hook thus putting the assembly under the dependence of the scheduler for the new period it will have scheduled.

La présente addition ajoute également au brevet principal un contact électrique qui se ferme par appui du crochet principal lorsque ce dernier arrive dans sa position d'ouverture et actionne alors un signal d'alarme d'alarme sonore et d'affichage visuel perçu à l'extérieur de l'espace protégé et dont un interrupteur manuel se trouve également-à l'intérieur ou d'ailleurs à l'extérieur de cet espace clos
Dans un dispositif selon la présente addition donné à titre d'exemple seuelement en référence à la figure 2 dela planche unique annexée , un crochet secondaire Il vient s'encastrer dans le crochet principal 4 lorsque celui-ci arrive dans la position haute et s'y encastre par l'effet duressort de compression 12 et de la forme en biseau du nez de cette sorte de goupille Il qui traverse la paroi 10 de la gche ou serrure et peut entre retirée en arrière à la demande , par un anneau 13 qui lui est solidaire , dégégeant alors la pièce 4
La présente addition comporte en outre deux bornes électriques 6 et 7 susceptibles d'être branchées à un circuit d'alarmes sonore at d'affichage visuel classique indépendant de celui de l'électro-aimant. L'une de ces bornes 14 est reliée à la masse l'autre 15 forme une lame de contact souple sur laquelle vient s'aDpuyer le nez de la pièce 4 lorsque celle-ci actionnée par le temporisateur a libéré le pène 2 . A ce moment il sera possible à une personne quiconque d'avoir accés par les moyens classiques d'ouverture de la serrure ( clef etc) à l'anneau 13 , et en tirant grâce alui la goupille Il de renettre le système en position d'attente , c'est à dire crochet 4 libéré et prèt à bloquer le pène 2 dés la fermeture et qui ne se débloquera que sous une nouvelle impulsion du programmateur aprés le nouveau délai qu'elle aura programmé. The present addition also adds to the main patent an electrical contact which closes by pressing the main hook when the latter arrives in its open position and then activates an audible alarm and visual display alarm signal perceived on the outside the protected space and with a manual switch also inside or outside of this enclosed space
In a device according to the present addition given by way of example only with reference to FIG. 2 of the attached single plate, a secondary hook It comes to be embedded in the main hook 4 when the latter arrives in the high position and s' recessed by the compression spring force 12 and the beveled shape of the nose of this kind of pin It which crosses the wall 10 of the keeper or lock and can between withdrawn back on demand, by a ring 13 which is interdependent, thus releasing the part 4
The present addition further comprises two electrical terminals 6 and 7 capable of being connected to a sound alarm circuit and conventional visual display independent of that of the electromagnet. One of these terminals 14 is connected to ground the other 15 forms a flexible contact blade on which the nose of the part 4 comes to be supported when the latter actuated by the timer has released the bolt 2. At this time it will be possible for anyone to have access by the conventional means of opening the lock (key etc) to the ring 13, and by pulling with the aid of the pin It to renounce the system in position wait, that is to say hook 4 released and ready to block latch 2 as soon as it closes and which will only be released under a new impulse from the programmer after the new delay it has programmed.

Claims

1- Additional system to the main patent characterized by the fact that a secondary hook, eg. 11 dela figure 2 of the single plank, automatically blocks the main hook of the bolt when this main hook has taken its unlocking position of the lock and can be released by means of an accessory external to the lock but internal to the space closed which can be for example the ring 13 or any other system of pull, push, slide or rotating button etc ...

2- Additional system to the main patent characterized in that an electrical contact closes automatically when the main bolt locking hook has arrived in its unlocking position, for example the contact14 of FIG. 2, then establishing a conventional circuit for audible alarm plus visual display perceived outside * of space and which can and can be deactivated by an internal or external switch in this space

3- System according to claims 2 and 3 characterized pr lefait that these additive devices can be applied to the manufacture of all currently known locks, strikes, bolts and linkages systems with which they can be associated by neighborhood or joined or by internal incorporation.
