Abstract
Abstract This invention comprises several embodiments of multi-functional shock mounts for transit/cases. A resilient (e.g., rubber) molded corner bumper is either bonded to, or captivated along its edges by, a retainer shaped to be demountably coupled to a corner of the case body or cover. The resilient molded portion may additionally be provided with an outer metallic jacket to facilitate sliding and protection thereof, the outer jacket in turn being either bonded to the resilient portion or being captivated along with the rubber by the retainer. The rubber bumper and its associated outer metallic jacket are extended in a cubical shaped center portion beyond the case outer dimensions and hardware, serving to recess same for additional protection. The resilient molded bumper may be in the form of a two or threelegged piece with the legs being retained by the case outer structural members. Additional features such as male and female stacking features, sloped edges to facilitate sliding, and tierings are provided. Shaped coring holes or cast slots or cross ribs in the resilient portion provide for the equivalent spring constant in all dropping and handling modes to be closely equal to the spring constant of the weight of the case and contents on a corner support.
