<p>The showcase includes a closure mechanism which compresses a seal by pulling the door panels against the main frame from inside. To this aim, a closure rod is mounted to the main frame which has alternating segments with expanded and contracted cross-sections, and a plurality of binding elements are mounted to the door panel for engagement by the rod. Each binding element has a rod-receving socket of sufficient width to accommodate the expanded cross-section segments of the rod; the socket is formed with a side gap for admitting the rod whose width allows the contracted cross-section segments of the rod therethrough but not the its expanded cross-section segments. <IMAGE></p> |
