In a conventional show case equipped with such a shielding curtain, the shielding curtain is rolled up and stored in the upper part of the front opening, and then the shielding curtain is pulled out as appropriate, and screws 20, 20, etc. are inserted in the lower part of the opening, as shown in Fig. 10. The locking metal fittings 11 of the shield curtain are locked to the attached locking claws 21 to close the front opening.

However, since the locking claw 21 for locking the shield curtain is fixed to the show case, it is easy to get injured by the catch claw when putting products in and out of the case or cleaning the show case, which is dangerous and reduces work efficiency. It is undesirable to lower the level.

[Purpose] The present invention eliminates the risk of injury due to the locking device for locking the shielding curtain, and provides an open case with a shielding curtain that allows operations such as loading and unloading products and cleaning the case safely and efficiently. I made it possible.

[Means] In order to achieve the above object, the open show case with a shielding curtain according to the present invention forms an air outlet for forming an air curtain inside the upper part of the front opening, and sucks air from this outlet. An inlet is formed at the lower part of the front opening, and a cooler and a blower are provided at appropriate locations in the air passage opening to the outlet and the inlet, and the inlet opening is provided with a cooler and a blower at appropriate intervals in the front-rear direction. A large number of small suction ports are formed by the partition plates, and a shielding curtain of a desired shape capable of closing the front opening can be drawn out and re-stored as appropriate from a storage section provided on the outside of the upper part of the front opening. In the show case, a locking tool is provided to be detachably attached to the partition plate of the suction port, and a locking part that is removably connected to the locking tool is provided at the lower part of the shielding curtain.

[Function] When using the shielding curtain, engage the engaging part of the locking tool with the partition plate of the suction port, arrange the locking tool on the opening surface of the suction port, pull it out from the storage part, and open the front opening of the show case. The shielding curtain with the section closed is locked to the locking tool.

When the shielding curtain is not in use, the locking part of the shielding curtain is removed from the locking tool, the shielding curtain is re-stored in the storage section, and the locking tool is removed from the opening surface of the suction port.

is formed.

Furthermore, a shielding curtain storage part 8 with a lower opening is provided outside the upper part of the front opening, and a shielding curtain 10 formed of, for example, a heat insulating waterproof sheet is mounted on a shaft cylinder 9 rotatably supported within this shielding curtain storage part. The shielding curtain 10 is stored in the shielding curtain storage section 8 by winding the shielding curtain.

Further, the shielding curtain 10 is attached to the shaft tube 9 at a proper position so that it does not come off the shaft tube 9 even when the shielding curtain 10 is pulled out from the shielding curtain storage part 8.
When the shielding curtain 10 is pulled out, the shielding curtain 1 is pulled out again.
Appropriate means is provided to generate a rotational biasing force in the direction of unwinding the zero on the shaft cylinder 9.

A reinforcing tool 10a is provided on the lower edge of the shielding curtain 10 to prevent the shielding curtain from bending.
A locking metal fitting 11 is attached to the lower part of the locking metal fitting 11, for example, at the lower end of the pin 11a that protrudes downward from the lower part of the locking metal fitting 11.
A spherical locking portion 11 made of a ball having a suitably larger diameter than the diameter of the ball.
b is provided.

Locking metal fitting 11 Metal fitting receiver 12 which is a locking metal fitting for locking
For example, the engagement plate 1 is formed of a metal plate that is slightly wider and thicker than the horizontal width of the small suction port 4b.
A locking hole 14 is provided at a proper position in the hole 1 that penetrates vertically, and the locking hole 14 has a required shape through which the spherical engaging portion 11b of the locking metal fitting 11 can be inserted.
4a, and a hole 14b of a constant width and an appropriate length provided continuously to the hole 14a.
The width is slightly wider than the diameter of the pin 11a, but is sufficiently narrower than the maximum diameter of the spherical locking portion 11b.

Furthermore, an engagement piece 15 is disposed on the lower surface of the engagement plate 13 via a joint 16 that is slightly thicker than the partition plate 4a and suitably shorter than the width of the small suction port 4b in the left-right direction. The lower surface of the plywood 13 and the engagement piece 15
A gap approximately the thickness of the partition plate 4a is created between the partition plate 4a and the upper surface of the partition plate 4a.

Like the engagement plate 13, this engagement piece 15 is suitably longer than the width of the small suction port 4b in the left-right direction, but when arranged diagonally to the small suction port, it can sufficiently pass through the small suction port 4b. It has the required shape that can be used.

In the case configured as above,
When using the shielding curtain 10, the metal fitting holder 12, which is a shielding curtain locking tool, is attached to the small suction port 4b as shown in FIG.
The engaging piece 15 is arranged so that it is positioned on the diagonal, and the engaging piece 15 is passed through the small suction port 4b, and the engaging plate 13 is placed on two adjacent partition plates, counterclockwise in the figure. direction, and arrange the metal fitting receiver 12 as shown in FIG.
