Description

"DOOR LOCKING SYSTEM"

The present invention relates to the field of door control, more particularly the control of the opening and / or closing of doors, even more particularly but not exclusively to the control of escape doors, called "emergency exits. »In case of fires and / or panic.

The ability to control the opening of a door may be particularly desirable. For example, the ability to prevent an emergency exit door from a public building (such as a store, cinema, museum, ...) from being easily opened may be desirable for security reasons. Although there are many locking mechanisms that could be used to control the opening of the door, the existing locking mechanisms generally cannot be used as they are as they are unsuitable for certain situations such as the fit between the doors. property security requirements and personal safety.

Specifically, existing locking mechanisms generally only allow the door to be released if the appropriate key is used to unlock the locking mechanism. In this regard, some safety standards require locking mechanisms to release the door without a key so that it can be opened relatively easily (eg with an anfipanic bar).

However, these mechanisms only ensure the safety of persons and not the safety of property, by authorizing the free exit of anyone without any discrimination.

The document US Pat. No. 5,065,136 discloses a security system for an exit door having an elecfroaiman † and an armature for. lock an exit door. The system consists of an electromagnetic housing and a frame assembly in which the housing is pivotally mounted on the frame assembly. The lock is automatically unlocked after a preset time delay. US 4,763,937 discloses an electromagnetic door locking system having an electromagnetic lock which magnetically bonds with a frame plate. An acoustic sensor generates a detection beam that is directed at a door handle. The lock is automatically deactivated when a foreign object is detected near the handle. The system can also include an audible alarm and indicator lights to indicate the status of the lock, mounted on the housing.

Document US Pat. No. 4,652,852 shows a building comprising several exits, each of them having a device for unlocking the corresponding exit. The building further includes at least one security guard post. When the unlocking device is activated, the information is sent to the security guard station and a predetermined time is triggered, during which the security guard can cancel the unlocking of the exit. The unlocking device further includes a visual indication for determining exit events. The unlocking device consists of an electromagnetic lock, a sensor that detects the movement of the unlocking device and a control line connecting the output to the security guard station. US 4,703,962 discloses a magnetic door lock having a time delay, in which the door lock comprises an electromagnet mounted on a door frame and a frame mounted on a door. The elecfroaiman † features a pair of laterally spaced slots that each have switches reed or magnetic switches to monitor magnetic flux from reelectromagnet. If, due to tampering or for any other reason, the magnetic flux drops below a selected level, at least one of the reed switches will remain open, indicating that the armature is not securely engaged with the electromagnet.

Document EP 2 049 753 is also known from the prior art, which discloses a device for locking a door, more precisely a magnetic door lock, which comprises magnetic locking means having an armature e † at least one electromagnet † e † includes mechanical locking means associated with magnetic locking means. The mechanical locking means comprise at least one locking element which serves to resist the separation of the reinforcement e † from the electromagnet. In addition, the magnetic door lock according to this prior document comprises at least one microswitch functioning as a pressure sensor because it is arranged to detect the movement of the electromagnet associated with an attempt to force open the door.
