<p>PURPOSE: To enlarge the size of a pillarless display case or the like and to enhance the freedom of designing by laying a stationary rail from which a predetermined length of a middle part is cut off, on each of a case body and a door panel. CONSTITUTION: Upon hermetically closing, the full load of a door panel 2 can be born by movable supports 8r, 81 having cam followers 11r, 11l running on a stationary rail laid on the upper edge of a door panel 2. After the door panel 2 is clockwise opened, when the cam follower 11l having born one-half of the full load of the door panel 2 comes off from the rail 61, the main load of the door panel 2 is shifted onto a cam follower having moved on the stationary rail 5r on a case body 1, and the cam follower 11r prevents the door panel 11 from oscillating, and also serves to prevent eccentricity. After the door panel 2 is further moved rightward, when a stationary support member 10 reaches the side face end, the cam follower 11r having run on the stationary rail 6r on the door panel 2 side, reaches the cut-off position of the rail, and it is released from the loading condition. When the door panel is turned by an angle of about 90deg., the front door panel 2 is completely opened.</p> |
