Abstract

A latch system is provided having utility in securing a planar member in a closed position within a housing having a portal. A base plate is secured to the planar member and a rotatable member having a generally circular periphery is coupled to the base plate. A cover is secured to the base plate and rotatably retains the rotatable member thereon. The cover includes a generally circular aperture having a diameter less than that of the periphery of the rotatable member, wherein upon assembly the generally circular periphery of the rotatable member opposes the generally circular aperture of the cover. At least one detent protrusion is formed on either the generally circular periphery of the rotatable member or the diameter of the generally circular aperture in the cover. At least one detent recess is formed in the other of the generally circular periphery of the rotatable member or the diameter of the generally circular aperture and opposes the detent protrusion. The detent recess is formed such that, upon engagement with the detent protrusion, purely rotational movement of the rotatable member causes axial movement of the rotatable member relative to the cover and disengagement of the detent protrusion with the detent recess. A pair of elongate members are coupled to the rotatable member such that rotation of the rotatable member causes the elongate members to reciprocate in and out of engagement with the apertures in the periphery of the portal.
