SNAP-LOCKING HINGE JOINT

摘要

A snap-locking hinge joint includes a clevis member and a flange member. The clevis member has a clevis base from which extend a pair of parallel arms forming a gap therebetween. Each of the arms has a pivot side and an engagement face transversely opposite the pivot side, and each of the arms has a locking recess formed in the engagement face adjacent the clevis base. The flange member has a flange base from which extends a planar rib and a pair of locking fingers. The locking fingers each have an inwardly protruding locking tip. The rib is received in the gap of the clevis member. The arms are pivotally engaged with the rib thereby pivotally interconnecting the clevis and flange members. In a locked configuration, the locking tips of the locking fingers are captured in the locking recesses of the arms of the clevis member.

1. A snap-locking hinge joint comprising:
a clevis member having a clevis base from which extend a pair of parallel arms forming a gap therebetween, each of said arms having a pivot side and an engagement face transversely opposite said pivot side, and each of said arms having a locking recess formed in the engagement face adjacent said clevis base, a flange member having a flange base, a planar rib extending from said flange base, and a pair of locking fingers extending from said flange base and extending transversely from opposite sides of said rib,
each of the locking fingers including a distal end having an inwardly protruding locking tip,said rib having a pivot side transversely opposite said locking fingers, and said rib received in the gap of said clevis member,said clevis and flange bases for extending struts therefrom, andthe pivot sides of said arms pivotally engaged with the pivot side of said rib thereby pivotally interconnecting said clevis and flange members, and a locked configuration in which the locking tips of the locking fingers of said flange member are captured in the locking recesses of the arms of said clevis member.
