V. Description of the invention (4) The frozen display cabinet is composed of the thermal insulation box 3 of the upper mask opening 2. The thermal insulation box 3 is a steel outer box made of the upper mask opening 4. In the outer box 4, a hard synthetic resin inner box 6 with an upper mask opening is placed at intervals, and the opening edge of the inner box 6 is formed to continuously extend outward and connect the two boxes 4, 6 openings The interlaced part 7 of the edge and the foamed polyurethane insulation material 8 foamed and filled in the spaces of the two boxes 4 and 6. The upper opening 2 is formed to be inclined upward from the front side toward the back side. Therefore, the inner box 6 constitutes a storage room 9 for storing goods. The cooling device is cooled to a predetermined freezing temperature. On the other hand, a stepped drop is formed around the inner sides of the upper and lower sides of the interlaced part 7, and the upper and lower sides constitute the track parts 1 and 12, respectively. At this time, due to the foregoing The opening 2 is inclined upward toward the inward side, so the two rail portions 11, 12 are also parallel to this inclination, whereby the inner edge of the upper rail portion 丨] forms a pure angle, while the inner edge of the lower rail portion 12 The eighth series forms an acute angle. The outer side wall 12B of the rail portion 12 intersects the rail portion 12 at a right angle. Then, on the rail portions 11 and 12, two cover bodies 13 and 14 are slidably mounted. Each cover 13, 14 is made of a hard synthetic resin window frame 16, 17 around it and a transparent glass (also transparent acrylic resin plate) 18, 19 embedded in this window frame] 6, 7 Both of them can slide on the rail part in the left-right direction, and the cover 14 overlaps the lower side of the upper cover 13, and the lower cover 14 is formed in the vertical direction of the upper cover 13 The size is small.

Description of the invention (5)' -— The flanges 21, 22 protruding downward are formed on the outer periphery of the underside of each window frame 16, 17 of the cover 13, 14 The upper flange 21 of the upper cover 13 slidably abuts the upper surface of the rail portion H, while the lower flange 21 front surface contacts the outer wall 12B of the rail portion 12. Moreover, the flange 22 on the upper side of the lower cover 14 is slidably abutted on the upper surface of the rail portion 11 than the inner side of the flange 21, while the lower flange 22 is slidably abutted on the inner side of the flange 21 Connected to the lower surface of the rail portion 12. Furthermore, the flange 21 of the upper cover 13 is higher, and the flange 22 of the lower cover 14 is lower, so that the lower cover 14 can be fitted into the lower side of the upper cover 13. Further, from the lower surface of the window frame Π of the lower cover 14 is formed a rib member 23 protruding downward that is sag relative to the window frame 11, and the rib member 23 slidably abuts on the aforementioned acute angle forming member The inner edge 12A of the rail portion I). When the opening 2 is opened and closed, the lids 13 and 14 are moved to the left and right in this way. In the present invention, a rib member 23 protruding downward is formed under the window frame 17 of the lower cover 14 as described above. Since the rib member 23 slidably contacts the inner edge 12A of the rail portion 12, the lower The inverted cover 14 does not cause movement toward the lower side of the opening 2 due to gravity, and does not cause sliding due to squeezing of the upper cover 13. Therefore, the opening and closing operability of the two lids 13, 14 can be improved, and at the same time, the deterioration caused by the abrasion of the two can be avoided in advance. Furthermore, since the lower cover 14 moves, the cover 14 can be prevented from falling into the storage compartment 9. Next, FIG. 3 shows a display cabinet 1 of another embodiment. At this time, in addition to the size of this paper, the Chinese National Standard (CNS) A4 specification is applicable (2 丨 0 > < 297 gong) -17 ------, sister (please read the precautions on the back before filling this page) Economy Ministry of Central Standards Bureau employee consumption cooperation Du Yince A7 V. Description of invention (6) ----- In addition to the display cabinet 1 in Fig. 2, plus the outside of the flange 21 protruding from the lower side of the window frame 16 of the upper cover 13 ， 和 Unitely formed rib member 24. Moreover, the rib member 24 slidably abuts the outer side wall 12B of the rail portion 12. As a result, the lower side of the upper cover 13 and the outer wall ι2β of the rail portion 12 are in linear contact with the rib member, so that the friction between the two can be reduced to further improve the opening and closing operability of the cover 13. 'Next, Fig. 4 shows the overview of another embodiment. At this time, in addition to the display cabinet 1 shown in FIG. 2, the side wall 12B formed by the front of the lower rail portion 12 of the opening 2 forms an inclined surface inclined upward toward the front side. By this, the outer side wall 12B and the rear portion (inner side) of the rail portion 12 form a corner portion 2c that intersects a pure angle in the left-right direction. Therefore, since the flange of the window frame 16 at the lower side of the upper cover 13 and the lower end of η slidably abut on the corner portion 12C, the lower side is in line contact with the rail portion 12 as above. The friction between the two can be reduced to further improve the opening and closing operability of the cover 13. In particular, since the movement of the upper cover 13 is also restricted by the corners 12, the movement in the up-down direction becomes more difficult, so that not only the opening and closing operability is improved, but also the cover 3 can be prevented from falling off. Next, FIG. 5 shows another display cabinet of the present invention.
