Abstract

PROBLEM TO BE SOLVED: To simply mount and remove a roller. SOLUTION: Protrusions 52 are projected from front and rear surfaces of a square groove 51 formed in a lower frame member 47 near a lower end. A roller set 54 is detachably contained in a space formed between a bottom 51a of the groove 51 and both the protrusions 52. The set 54 has a mounting member 58 and a roller 60 rotatably supported with the member 58 through a supporting shaft. Supports 58b opened down are formed at lower edges of vertical plates 58a opposed to front and rear sides of the member 58. When the set 54 is contained in the groove 51, lower ends of the plates 58a are disposed opposite to the protrusions 52 in contact relation, longitudinal movements of both shaft ends 59a of a supporting shaft are restricted by the supports 58b, received by the protrusions 52 and inhibited to be released.

As shown in FIG. 7, the lower rail 32 has a front rising portion 32b and a rear rising portion 32c rising at a predetermined height at front and rear end edges of a horizontal portion 32a, and has a total length in the longitudinal direction (width direction). , And a groove 32d that opens upward is defined therebetween. Also, two rail strips 37 and 38 are erected on the upper surface of the horizontal portion 32a in the groove 32d so as to be spaced apart in the front-rear direction over the entire length in the longitudinal direction. Then, the front slide door 35 and the rear slide door 36 are provided with a roller set 54,
4, it is slidably supported by the corresponding rail strips 37, 38. A through hole (not shown) is formed at an appropriate position in the longitudinal direction in the horizontal portion 32a,
The condensed water or the like dropped into the groove 32d is drained into the drain pan 30
It is configured to lead to. In addition, the rail strip 37,
The upper end level of 38 is set so as to face lower than the inner bottom surface of the storage chamber 23, and when the front and rear slide doors 35, 36 are opened to allow display articles to enter and exit from the opening 14a, the rail strips 37, 38 are used. Is configured so as not to interfere. FIG.
As shown in FIG. 7, in the lower rail 32 of the embodiment, the height of the rear rising portion 32c is set so as to protrude slightly above the inner bottom surface of the storage room 23, so that water droplets dropped on the inner bottom surface of the storage room 23 It is prevented from flowing into the rail 32. In this case, the rear rising portion 32c protrudes upward from the inner bottom surface of the storage chamber 23, but if the same height is placed on the inner bottom surface, the rear rising portion 32c hinders the entry and exit of display items. Disappears.

Next, when the cooling operation of the refrigerated showcase 10 is started, the storage chamber 23 is cooled by the refrigerating device 19, the cooler 24, the fan motor 26 and the like. Depending on conditions such as the temperature difference between the outside air temperature and the room temperature, the outside humidity, and the like, dew condensation occurs on the outside surfaces of the front and rear slide doors 35 and 36, and the dew water flows down from the see-through body 42 to the lower frame member 47. . The lower end of the lower frame member 47 is attached to the lower rail 3
Since the tapered surface 53 facing the second groove 32d is formed, the dew water is surely dropped into the groove 32d of the lower rail 32,
The installation floor of the refrigerated showcase 10 does not get wet. Then, the condensed water dropped on the lower rail 32 is discharged to the drain pan 30 provided on the outer bottom of the heat insulating box 14.
