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.

A latch system having utility in securing a planar member in a closed position comprising: a kennel housing having a portal, said portal having a defined periphery with a plurality of apertures within said periphery, said planar member being pivotally mounted in said portal; a base plate secured to said planar member; a knob rotatably coupled to said base plate, said knob having a generally circular periphery; a cover secured to said base plate and including a generally circular aperture having a diameter less than that of said periphery of said knob, wherein upon assembly said generally circular periphery of said knob opposes said generally circular aperture of said cover to rotatably retain said knob on said base plate; at least one detent protrusion formed on one of said generally circular periphery of said knob and said cover adjacent said diameter of said generally circular aperture; at least one detent recess formed in the other of said generally circular periphery of said knob and said cover adjacent said diameter of said generally circular aperture and opposing said at least one detent protrusion, said at least one detent protrusion for engagement with said at least one detent recess to temporarily restrain said knob against rotation, said at least one detent recess being beveled such that upon engagement with said at least one detent protrusion purely rotational movement of said knob causes axial movement of said knob relative to said base plate and disengagement of said at least one detent protrusion with said at least one detent recess; a plurality of elongate members carried on said planar member for reciprocation into and out of engagement with said apertures within said periphery of said portal, said engagement of said elongate members with said apertures within said periphery of said portal restraining said planar member against movement in said portal; and means coupling said elongate members to said knob for reciprocating said elongate members into and out of engagement with said apertures within said periphery of said portal responsive to rotation of said knob.
