Utility model application

" Door - Lock "

Description:

The purpose of the facility is to detain the last of the unwanted visitors without endangering third parties during raids on institutions such as banks or savings banks, i.e.

1.) It must be ensured that the perpetrator(s) cannot threaten or hold hostage any employees of the institution or customers.

2.) At least one of the perpetrators must be detained and this must be done without endangering third parties.

Both can be achieved according to the invention by providing a revolving door that is sturdily built and fitted with bulletproof glass. It must also be possible for officials of the institute to lock it from their workstations - for example electrically by pressing a button.

The lock should be designed in such a way that, after being triggered, the revolving door only stops rotating when it has reached the position in which the person who wants to use it to leave the institution is trapped in the revolving door, i.e. cannot escape either to the outside or back in, i.e. is "locked in". Since a revolving door only has normal space for one person, there is no danger of a hostage being caught and if this should happen by force, the ^criminal can only wait ^with the police until the

called and arrived, he cannot escape. The function is now provided as follows:

The perpetrator(s) appear and demand money with a gun, threatening them (or holding another visitor hostage if necessary). - The money is handed over (as required, so as not to endanger human life). - The perpetrator(s) leave the room, inevitably through the new revolving door. - When the last perpetrator enters the revolving door, it is locked by pressing a button. The lock engages and holds the revolving door in a position in which the perpetrator cannot exit either forwards or backwards. The police can be called calmly and without danger to third parties. It is true that if there are several perpetrators, "only" the last one can be caught, because the danger to any customers present has not yet been eliminated. However, it is initially sufficient to have arrested at least one of the perpetrators, who can then be grilled during interrogation.

Of course, by installing two revolving doors of the type described one behind the other, it would also be possible to arrest two perpetrators. This is simply a question of cost and local conditions.

The only negative possibility is that the perpetrator(s) already know about the system that has been installed. This means that the prerequisite for this method to work is of course that the perpetrator is not given the opportunity to get inside the institution (to the officials) and from there to the outside through unsecured windows or doors! But it can be assumed that banks and savings banks are equipped with bulletproof counter windows so that at least the officials are not at risk. If this is not even guaranteed, then there is really no help for the institutions and their management -.

- Sheet 3 -

In an alternative embodiment, but with a certain risk that customers of the institute are also detained and thus endangered (although no more than if they were taken hostage), the invention idea can also be evaluated in the following way:

A revolving door has 4 door wings that are at an angle to each other. In accordance with the inventive concept, the offender is caught by the lock between 2 adjacent door wings. However, these two door wings can also be used separately. For example, the two doors of the so-called "vestibule" can be used for this purpose, for which they are each equipped with a lock that can be operated remotely (e.g. by pressing a button). - As soon as the last offender has entered the vestibule (the vestibule), both door wings are locked and the offender is caught, and the police are notified. - The advantage of this design: It is possible that not only the last offender is held alone. The disadvantage: A customer could also be held. This risk is small, as experience has shown that the offender(s) usually forces those present to lie on the floor so that they cannot be followed.

In order to largely eliminate the danger to visitors who are also trapped, the "prisoner's room" can be sprayed with a harmless anesthetic when the barrier is installed on a revolving door or on the vestibule doors, which temporarily incapacitates the detained persons.

Claims (5)

Protection claims : Claim 1.) Door lock(s), characterized in that the same(s) can be triggered remotely (e.g. mechanically or "electrically by pressing a button") and are attached to a revolving door or to the two doors of an anteroom (vestibule) in order to be able to lock the revolving door or the two anteroom doors remotely. 2.) Door lock(s) according to claim 1) characterized in that the locking device(s) is (are) provided with a locking cam that can be pre-tensioned by the triggering, which is initially pre-tensioned by the remote control, but only engages when the revolving door is turned or the anteroom door(s) is closed and thus locks the passage in the desired door position. 3.) Door lock(s) according to claim 1) characterized in that the door (or doors) are bulletproof and stable enough, i.e. escape-proof, and that therefore, if necessary, glazing is also made of bulletproof material. 4.) Door lock(s) according to claim 1.) characterized in that by the triggering of the door lock at the same time the electrical contact to alert the police is activated. 5.) Door lock(s) according to claims 1) and 3), characterized in that a sprinkling device is provided through which a harmless narcotic can be introduced into the room in which detained offenders are locked up.
