DETAILED DESCRIPTION

The examples described herein relate to door locks and in particular automatic door locks. Door locks are currently used on a variety of different devices. For example, they are used in vehicles such as an aircraft, for locking oven doors, hatches etc. The door locks described herein could be used to prevent an attack such as a terrorist attack in a vehicle such as an aircraft, wherein a heat generating product such as an oven could be used as a detonating device. In this way, the locks described herein may prevent any such future attacks.

Although the description here is given mainly in relation to an oven door of an aircraft, the locking system described herein could be used for any door wherein it is not intended that unauthorised people are able to unlock the door.

The door locking system for an oven galley insert door may comprise a locking system wherein a biometric device is provided, such that the oven door cannot open unless a recognised biometric feature is detected.

The internal components and functioning of one type of door lock that is used for an oven galley insert door having a primary and secondary latch is shown in FIG. 1. The biometric device can, however, also be used with door locking systems having different components and the examples described herein are not limited to this one type of door locking system.

As can be seen in FIG. 1, the locking system comprises a primary latch 10 that is moved by the user in order to open the door. The internal actuating gear 11 translates movement to a push rod 12 which is moved in a vertical direction as shown in FIG. 1. This, in turn, actuates a secondary latch 20, the mechanism 21 of which can be seen in FIG. 1. The secondary latch mechanism 21 comprises a striker slider mechanism that moves relative to the primary latch 10 to allow the primary latch 10 to open the door.

In the locking system shown in FIG. 2, a biometric device such as an automatic biometric lock 30 is incorporated into the locking system. The incorporation of the biometric device 30 into the locking system can be configured such that it activates the secondary lock 20 of the locking system and can only be opened by the detection of a registered fingerprint (or other biometric features) of the cabin crew. This therefore prevents unauthorised use of the heat generating device. In this example, in order to trigger the Striker Slider mechanism 21 of the secondary latch, an actuating motor or device is provided within the secondary latch mechanism 21 so that once a fingerprint is detected the actuator motor or device will Lock or Unlock the mechanism. The automatic biometric lock 30 is shown in FIG. 2.

As depicted in FIG. 4, the striker slider mechanism may comprise a striker 23 and a striker slider 22. In some examples, the biometric device 30 may be configured to indicate to the user whether or not the lock is in the unlocked position. For example, as shown in FIG. 3, the biometric device 30 may glow red when locked, or may show an icon indicating that it is locked. In this unlocked position, the striker slider 21 is not engaged with the striker 22 and the door is unlocked.

FIGS. 5 and 6 depict the locking mechanism when the door is in the locked position. As can be seen in FIG. 5, in the locked position, the biometric device 30 may indicate to the user, e.g. with colour, icon, etc, that the door is locked. As shown in FIG. 6, when in the locked position, the striker slider 21 is in a position wherein it engages the striker 22.

FIG. 7a depicts a front view of a traditional door locking system. The door locking system has a secondary latch 210 that has a manual mechanism. FIG. 7c depicts a back view of the same traditional locking system. As can be seen in FIG. 7b, the feature 210 is replaced with a biometric device in the new examples described herein.

FIG. 8a depicts a biometric device 30 that may be used in the examples described herein. The device may have a fingerprint screen 310. In some examples, a USB port 320 may be provided. FIG. 8b depicts the components of the biometric device of FIG. 8a, showing the cylinder 330 that may be configured to move up and down and thereby actuate the secondary latch in use. Internally, the biometric device may have a series of gears that are controlled by electronics and which may be triggered by the authorized biometric feature, e.g. Fingerprint. The trigger would make the cylinder 330 move up and down to actuate the slider for locking and unlocking the oven door. A memory chip may also be included to store the biometric data.

In summary, the installation of the Automatic Biometric Lock device 30 to the door locking system will therefore activate the Secondary Door Latch through locking and unlocking. It can only be opened by the registered fingerprint, or other biometric indication (e.g. facial, eye recognition etc.) of the authorized person, e.g. cabin crew. This will prevent the unauthorized use or operation of the Oven.

The door locking system for the galley insert oven may be manufactured via a method that comprises providing the galley insert oven, wherein the oven has a door, providing the primary latch 10 as described above, that is moved by a user in use to open the door; and providing a secondary latch 20, as also described above, such that it is positioned internally of the oven. The method may further involve installing the biometric device as described above relative to the primary latch and the secondary latch such that, in use, activation of the biometric device results in movement of the secondary latch 20.

As described above, the biometric device that is installed may be configured to detect and confirm a registered biometric feature.

As also described above, the biometric feature may comprise one or more that one of a fingerprint, facial features, eye features and recognition of an authorised biometric feature by the biometric device may result in movement of an internal actuating gear 11, which actuates the secondary latch 20.

The method of manufacture may further comprise providing a secondary latch that comprises a secondary latch mechanism comprising a striker slider that locks or unlocks a door on which the locking mechanism is installed.

The method of manufacture may further comprise providing an actuating motor or device within the secondary latch mechanism 21 that is configured to trigger the secondary Slider mechanism 21 of the secondary latch when a biometric feature is detected by the biometric device 30.

Although this disclosure has been described in terms of preferred examples, it should be understood that these examples are illustrative only and that the claims are not limited to those examples. Those skilled in the art will be able to make modifications and alternatives in view of the disclosure which are contemplated as falling within the scope of the appended claims.
