Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an open show case equipped with a film called a night cover that protects an air curtain at night.

(B) Prior art As shown in Japanese Utility Model Application Publication No. 50-81798, this type of open show case has a stop that extends rearward inside a so-called handrail section on the upper part of the front wall of the main body, which is the lower end of the front opening. A locking tool is provided, and a locking tool at the lower end of the film is locked to this stopper.

(C) Problems to be Solved by the Invention According to the above-mentioned conventional technology, because the upper surface of the handrail portion and the stopper are located at approximately the same height, when a customer picks up a product from the lower part of the storage room, the stopper There were problems such as the sleeves of clothing getting caught and the risk of injury to hands.

The present invention aims to solve such problems.

(d) Means for Solving the Problems In order to solve the above problems, the present invention provides an elongated sash at the end of the film, a locking device attached to this sash, and a large number of suction holes. A configuration is adopted in which a suction plate is provided to cover the suction port, and the locking tool is passed through any one of the suction holes and locked to the suction plate.

(E) Function According to the above means, the suction plate acts not only as a guard to prevent articles from falling from the suction port into the cold air passage, but also as a locking member for the lower end locking device of the film.

(F) Example The example will be explained below with reference to the drawings.
FIG. 1 shows an open show case whose main body is composed of a heat insulating wall 2 having an opening 3 on the front. A partition plate 4 is arranged at an appropriate distance from the inner wall of the heat insulating wall, and a cooler 7 and a blower 8 are installed. A cold air passage 5 in which a refrigerator is installed, a storage chamber 6 having a shelf 9, and an air outlet 10 and an inlet 11 are formed at the upper and lower ends of the opening, and a cooler 7 exchanges heat. Cold air is forcedly circulated by a blower 8 to form a cold air curtain A in the opening 3 to cool the storage chamber 6. Reference numeral 12 denotes a drainage hole formed in the bottom wall 2a of the heat insulating wall, which is located on the windward side of the cooler 7 and the blower 8, that is, on the low-pressure side of the cold air passage 5, and is connected to a drainage pipe 13 for guiding dew to the outside, which will be described later. is connected.

Reference numeral 14 denotes a winding and automatic return type film provided on the outside of the upper part of the opening, and a locking tool 1 provided at the lower end of the film when necessary such as when the store is not open at night.
5 downward, and attach the locking tool to the suction hole 17a on the suction plate 17 that covers the suction port 11 as shown in FIG.
That is, the locking tool 15 is attached to the outside of the air curtain A by locking it through the suction plate 17 located inside the front wall 2b of the heat insulating wall 2 so as not to obstruct the suction of the air curtain A. Due to this locking, a gap D is formed between the lower end of the film 14 and the inner surface of the front wall 2b to separate the lower end of the film 14 from the front wall 2b. The suction plate 17
is a so-called perforated plate, and has a large number of suction holes 1 in a suction plate 17 that is lower than the upper surface of the front wall 2b and covers the suction port 11.
7a is formed, among which any suction hole 1
By passing the locking tool 15 through 7a, the locking tool 1
5 is hooked on the suction plate 17. That is, the suction plate 17 not only functions as a guard to prevent articles from falling from the suction port 11 into the cold air passage 5, but also functions as a locking member for the lower end locking tool 15 of the film 14. The sash 18 is provided along the lower end of the film 14, and the locking tool 15 is attached to this sash.

When the lower end of the film 14 is attached to the suction plate 17 as described above and the film 14 is attached to the outside of the air curtain A to perform a cooling operation of the open shower case 1, the film 14 becomes a boundary between cold air and outside air. If the ambient conditions of the open-shot case 1 are bad, the temperature of the surface of the film 14 exposed to the outside air will be below the dew point temperature, and a large amount of dew will occur on the surface. This dew is transferred from the lower end of the film 14 to the suction port 11.
and flows through the cold air passage 5 to the drain hole 12 and the cooler 7
It is discharged to the outside from the drain pipe 13 along with the dew from the water.

According to the above structure, the sash 18 is provided at the lower end of the film 14, and the locking tool 1 is attached to the sash 18.
5, the sash 18 acts as a reinforcing material for the lower end of the film 14.
When the locking tool 15 is used as a handle and pulled downward, a tensile force is evenly applied to the lower end of the film 14, so that the lower end of the film 14 is not cracked and the durability of the film 14 can be improved. In addition, since the suction plate 17 formed with the suction hole 17a through which the locking tool 15 is passed acts as a support member for the locking tool 15, that is, a stopper, a stopper is not provided inside the handrail at the upper part of the front wall as in the prior art. Therefore, when the film 14 is automatically returned and wound and stored in the upper part of the opening 3, the suction plate 17, which also serves as the film lower end support member, does not pose any obstacle to the customer. It is possible to improve the safety of customers when taking out items.

The above-mentioned proposal has the following effects: Since a sash is provided at the bottom end of the film and a locking device is provided on this sash,
Since the sash acts as a reinforcing material at the bottom edge of the film, when the lock is pulled downward, tension is applied evenly to the bottom edge of the film, resulting in cracks at the bottom edge of the film. This improves the durability of the film.

The suction plate acts as a support member for the locking device in order to lock the locking device in the suction hole through the suction hole, and therefore, when the film is automatically returned and wound and stored in the upper part of the opening, The suction plate, which also serves as the lower end support member of the film, does not pose any obstacle to the customer, and as a result, the safety of the customer when taking out articles can be improved.
