Patent ID: 8714602

Claim:
A locking device for locking a structural element to an adjacent structure, the device being provided with a latch suitable for being arranged on said structural element and with a retaining pin suitable for being arranged on said adjacent structure, said latch comprising firstly a handle having an oblong orifice in which there is inserted a fastener sleeve fastening it to said structural element, and secondly a locking arm having a first end hinged to said handle via a pivot peg, said handle including a release catch suitable for preventing said handle from tilting relative to said locking arm, wherein said retaining pin has first and second transverse branches that are separated by a space, a second end of said locking arm has a contact finger having on either side a first surface facing said first end and a second surface opposite from said first surface, said first surface constituting closure means that co-operate with said first transverse branch to lock said locking device, said second surface constituting extractor means for extracting said latch that co-operate with said second transverse branch to move the latch longitudinally away from the retaining pin, said contact finger then being outside said space so as to unlock said locking device, said second surface having a plane portion suitable for being in contact with said second transverse branch, wherein said release catch moves to separate said handle from said locking arm, wherein said handle moves through a first angular sector (θ 1 ) such that said plane portion of the second surface is pressed against said second transverse branch, wherein said handle moves through a second angular sector (θ 2 ) such that said second surface exerts a force on said second transverse branch and moves said structural element away from said adjacent structure, and wherein said handle moves through a third angular sector (θ 3 ) such that said contact finger is extracted from said space.
