An easily separable but conventional-appearing hinge wherein the hinge flaps can be connected or disconnected to/from one another without relative lengthwise displacement of the flaps by employing short axial movement of the hinge pin. The flaps thus may be hingedly securely connected together, or disconnected and separated within limited space. The flaps have tubular knuckles with adjacent space or gaps so knuckles of one flap can be interdigitated with knuckles of the other flap and held together by the hinge pin. Knuckles of one flap are slotted longitudinally forming open sided or split tubes; those of the other flap are fully tubular, i.e., unslotted. The removable hinge pin has adjacent cylindrical and flat portions, the latter positionable in gaps longitudinally aligned with the full tube knuckles of one of the flaps. The slotted knuckles of the other flap can be fitted transversely over the pin\s flat portions thereby axially aligning the knuckles of both flaps with the pin fully encased and axially slidable therein. So positioned, the flaps can be disengaged by sliding the slotted knuckles in reverse transverse direction until free of the pin\s flat segments. The flaps lock together for normal hinge action, or unlock for separation, by short axial movement of the pin between a locked position in which the pin\s cylindrical portions are within the slotted knuckles and an unlocked position in which the pin\s flat portions are within the slotted knuckles. One flap has a spring well with coil spring therein axially of the hinge pin to normally bias the pin to the flap-locking position. Pin actuator means can be provided to move the hinge pin between locked and unlocked positions and to rotate the pin to direct edges of the flat segments towards the slots of the open-sided knuckles.

An easily separable hinge device of conventional appearance, in which the hinge flaps may be hingedly connected together, or disconnected within limited working space by only short axial movement of the hinge pin, comprising: first and second hinge flaps for attachment to structures to be hinged together; each flap having tube-like knuckle means with longitudinally adjacent gap means in castellated formation with said knuckle means; the knuckle means of one of the flaps adapted to be interdigitated and axially aligned with knuckle means of the other flap; the knuckle means of one of the flaps provided with longitudinal slot means opening through one side thereof; hinge pin means positionable in and pivotable in knuckle means of both of said flaps for hingedly holding one flap to the other; said hinge pin being formed along its length with flat and cylindrical portions slidable in said knuckle means; said slot means adapted to slide transversely of said pin over said flat portions thereof positioned in gap means of said first hinge flap to position said slotted knuckle means around the hinge pin and axially align the knuckle means of both flaps or to separate said slotted knuckle means from said pin and said first flap; said hinge pin being axially slidable in said knuckle means between a first or unlocked position in which said flat portions are positioned in the gap means of one of the flaps whereby the knuckle means of the flaps may be brought into alignment, and a second or locked position in which said cylindrical portions are within said slotted knuckle means whereby said flaps are prevented from being separated at all pivotal positions of the flaps.
