A lockable hinge device of the type having a female flap and a male flap for attachment to structures to be hinged together and having interfittable knuckles defining together a passageway. A hinge pin is insertable into the passageway to pivotally connect the female flap to the male flap. The female flap has an outermost knuckle with a longitudinal slot extending through the entire length thereof. That slot is associated with a cut provided on the edge of the male knuckle adjoining the outermost female knuckle. The flaps are thus pivotable between an unlock position where the cut is in an aligned relationship with the slot and a lock position where the cut is in an unaligned relationship with the slot. On its side, the hinge pin has along its length a tooth projecting therefrom. The tooth is sized to freely slide in the slot and to fit entirely in the cut thereby allowing the hinge pin to be inserted in the passageway while the flaps are pivoted in the unlock position with the slot guiding the tooth up to said cut to sit therein, and then as the flaps are pivoted in the lock position, the tooth sitting in the cut is caused to slide under the inner edge of the female outermost knuckle thereby locking the hinge pin in the passageway. |
