1. A latch assembly comprising:
a post having a first end mountable to a first member in a cantilever manner, the post having a free end having a circumferential groove inboard thereof; a handle base mountable to a second member, the second member and handle base each having respective aligned openings for receiving the free end of the post therethrough, the handle base including:
a pair of opposed guide arms; anda pair of opposed resilient latch arms, the pairs of opposed resilient latch arms and guide arms depending from a same side of the handle base and being axially aligned with the opening in the handle base with each latch arm having a catch at a free end thereof; and, a handle slidably coupleable to the handle base and axially movable within the handle base, the handle including:
a support body having a first end and a second end, the support body having an axial opening extending between the first and second ends and a pair of opposed channels axially extending along an outer surface of the support body from the first end and aligned with the pair of opposed guide arms and sized for receiving therein a corresponding guide arm;a grip axially depending from the second end of the support body having an opening therein aligned with the opening in the handle base and sized for receiving the free end of the post;an end wall radially extending from the support body and positioned adjacent to the second end thereof;at least two opposed rails axially positioned between the first and second ends of the support body, each rail having:
a first and a second end extending along the outer surface of the support body from the first end of the support body toward the second end of the support body, the second ends of the at least two opposed rails being spaced apart from the end wall forming a respective dwell gap therebetween sized to receive therethrough the respective catches of the pair of opposed resilient latch arms;an inner ramp having a bottom beginning adjacent to the second end of each rail and raising at a predetermined first acute angle; andan outer ramp having a bottom beginning adjacent to the first end of each rail and raising at a predetermined second acute angle, the catches moveable along respective outer and inner ramps, wherein, with the post mounted in the first member, the handle base mounted on the second member and the handle installed in the handle base, during mounting of the second member onto the post using an axial pushing force applied to the handle, the free end of the post initially separates the catches and deflects the pair of opposed resilient latch arms with the catches subsequently engaging the groove on the post and the pair of opposed resilient latch arms returning to a less deflected position thereby latching the second member to the post, and, during dismounting of the second member from the post using an axial pulling force applied to the handle, the catches slide up the inner ramps of the at least two opposed rails and disengage from the groove in the post separating the catches by a distance sufficient to allow the second member to slide off of the free end of the post. |
