A releasably lockable hinge device comprises a pair of hingably connected hinge members rotatable about a common pivot and mutually positionable in an at least one mutually releasably locked position by a locking pawl selectively movable between locking and unlocking positions. One and another surface portions of the locking pawl, when biased into a locking position, are interferingly wedgingly engaged with respective corresponding surfaces of the pair of hinge members, in rigidly, bridging interlocking relation therebetween. |
