CA 2155344
A building system has interlocking frame members which interengage to form a rectilinear frame. To prevent the interengaged frame members from disengaging, a lock element is associated with a joint between frame members. This lock element is a rotary lock with a trilobal locking surface. Additional locking capability can be provided by a lock ring or collar which surrounds a joint between two frame members and prevents unintentional disengagement.
Système de construction possédant des éléments de structure emboîtés, mutuellement accouplés de façon à former une structure rectiligne. Afin d'empêcher la séparation des éléments de structure emboîtés, on place entre ceux-ci un élément de verrouillage. Cet élément de verrouillage est rotatif et présente une surface de verrouillage à trois lobes. Un verrouillage additionnel peut être obtenu à l'aide d'un anneau ou collier entourant la jonction entre deux éléments de structure, empêchant ainsi leur séparation involontaire.
