Abstract
A latch device releasably secures a container to a support surface. The device comprises a housing, a latch, interchangeable spring sets, and a pin. The housing comprises an upper shell and an inner coil-receiving cavity. The shell defines a latch-receiving cavity. The latch comprises an upper latch end and a coil-engaging portion. The coil-engaging portion comprises coil-aligning structure. At least one compression coil is received within the coil-receiving cavity and placed into engagement with the coil-engaging portion so as to bias the upper latch end exterior to shell via the latch-receiving cavity. The coil-aligning structure enhances axial alignment of each coil during coil compression. The pin pivotally connects the latch to the housing for enabling pivotal movement of the latch under selectively varied spring resistance for targeted applications. The coil(s) thus enable the user to vary latching forces during latching securement and release depending to the targeted loads and conditions.
