Title (EN) A LOCK FOR A TAMPER RESISTANT ASSEMBLY
(FR) VERROU POUR ENSEMBLE INVIOLABLE
Abstract:
(EN) A tamper-resistant lock assembly comprising a plate(16) having a slot (20)for receiving a key(10), said slot (20) extending through said plate (16)from an opening (20a) in a front face thereof to an exit (20b) in an opposing rear face thereof, said opening (20a) having a first profile and said exit (20b) having a second, different profile, said key (10) comprising a shaft (12) having a bit (14) extending therefrom, said bit (14) being formed of a shape memory material and being pre-configured such that its cross-sectional shape in its temporary form matches said first profile and said bit (14) can be inserted through said slot (20) via said opening (20a) and, upon application of a predetermined external stimulus, returns to a permanent form in which its cross-sectional shape matches said second profile and said bit (14) can be retracted from said slot (20) via said exit (20b).
(FR) L'invention concerne un verrou pour ensemble inviolable qui comprend une plaque (16) ayant une fente (20) pour recevoir une clé (10), ladite fente (20) s'étendant à travers ladite plaque (16) d'une ouverture (20a) dans une face avant associée à une sortie (20b) dans une face arrière opposée associée, ladite ouverture (20a) ayant un premier profil et ladite sortie (20b) ayant un second profil différent, ladite clé (10) comprenant un arbre (12) ayant un bit (14) s'étendant à partir de ce dernier, ledit bit (14) étant formé d'un matériau à mémoire de forme et étant pré-configuré de sorte que sa forme de section transversale dans sa forme temporaire correspond audit premier profil et ledit bit (14) peut être inséré à travers ladite fente (20) par l'intermédiaire de ladite ouverture (20a) et, lors de l'application d'un stimulus externe prédéterminé, revient à une forme permanente dans laquelle sa forme en coupe transversale correspond audit second profil et ledit bit (14) peut être retiré de ladite fente (20) par l'intermédiaire de ladite sortie (20a).
