ABSTRACT:
A multi-shelf type of showcase comprises a number of shelf plate supported substantially in a horizontal position at different levels. A shelf plate at each shelf level consists of a rear shelf section carried by shelf supports on the left and right sides of the showcase, and a movable front shelf section fitted in said rear shelf section slidably in the forth and back directions. The movable front shelf section can be drawn out forwardly of said rear shelf section upon using the same, while it can be inserted and accommodated within said rear shelf section when it is not in use. According to one aspect of the present invention, the respective rear shelf sections are fixedly secured to a framework of the showcase. However, according to another aspect of the invention, each of said rear shelf sections is pivotably mounted on a framework of the showcase so as to be rotatable upwardly about an axis at the rear end portion thereof. The front shelf section is provided with a latch protrusion at its front end portion, while on the bottom surface of the rear end portion of said rear shelf section and on the bottom surface of the rear end portion of a top wall of said showcase are respectively provided latch receiver means adapted to be engaged with said latch protrusions of said respective front shelf sections when each said front shelf section is accommodated in the associated rear shelf section and rotated upwardly about said axis jointly with said rear shelf section. In this mode of embodiment, when both the front and rear shelf sections become unused, said rear shelf section having said front shelf section accommodated therein can be rotated upwardly about said axis and locked at a substantially vertical position by engagement between the latch protrusion and the latch receiver means.
