Description

[Detailed explanation of the invention] (a) Industrial application field The present invention is an open-sided open show case with a front opening, and the left and right ends of the upper wall, back wall, and bottom wall are reinforced by providing frames that connect these walls. The present invention relates to an open shell case that is easy to assemble so that the frame can be corrected to be bulged outward under the load of the upper wall and maintain its normal shape.

(b) Conventional technology The main body of the show case, which has an airflow curtain formed at the front opening and has a top wall, a back wall, and a bottom wall, was developed in 1977.
It is well known from publications such as No.-11586 and Utility Model Publication No. 57-1815.

In this case, if the ceiling wall, back wall, and bottom wall are made separately, a frame shaped along the left and right end surfaces of each of these walls is installed on both the left and right end surfaces of these walls in order to connect and hold these walls together. It is fixed with screws. This frame is made of a plate so that it does not get in the way when multiple open show cases are connected horizontally, so if the load on the top wall or back wall is large, it will bulge slightly outward, allowing the open show cases to connect together. This may cause problems in the connection of the frames, or may cause problems in the installation of various parts to be attached to the frame.

(c) Problems to be solved by the invention As mentioned above, the invention provides a holding member to correct the outward bulge of the frame connecting each wall and maintain it in a normal state. A structure is provided to facilitate the work of connecting this member and the frame.

(d) Measures to solve the problem A series of screws are attached to the left and right ends of the upper wall, back wall and bottom wall of the case body, which forms an airflow curtain at the front opening of the product storage room. In the device provided with a frame, a support member that supports the rear end of the bottom plate provided at the lower part of the product storage chamber is provided lying between the left and right frames, and the right and left ends of the support member are provided with the respective frames. A coupling hole for screwing into the frame, and a locking hole in at least one of the left and right end portions, into which one tip of a pinch-type straightening tool locks between the frame and the frame.

(E) Action After the upper wall, back wall, and bottom wall are combined and the frame is attached to each wall, the frame is fixed by using a pinch-type straightening tool between the locking hole of the support member and the outer surface of the frame. A predetermined shape can be maintained by correcting the bulge, aligning the coupling hole of the support member with the coupling hole of the frame, and coupling the support member and frame with screws.

(F) Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 4. Reference numeral 1 denotes an open case, which has an upper wall 2 forming a ceiling wall, a case main body 5 composed of a back wall 3 and a bottom wall 4, and left and right side walls 6 connected to the left and right ends of the main body 5. A wide opening is formed in the front for taking out products. Behind this front opening 7 is a product storage room 9 in which multiple shelves 8 are installed.
The product storage chamber 9 also includes a partition plate 10 arranged at a distance from the main body 5 so as to form an airflow passage 26 between the main body 5 and the front opening 7 to form a cool or warm air flow. Compartments are formed. A cooler or heater 24 and a blower 25 for producing cold or warm air are housed in this airflow passage. The upper wall 2, the back wall 3, and the bottom wall 4 each constitute a heat insulating wall in which foamable polyurethane resin is injected and foamed into the space between the outer panel and the inner panel, and each wall has joints 11 and 12. It is joined at.
The bottom wall 4 includes a bottom wall 4A, a front wall 4B, and a rear wall 4C. 13 is a frame fixed to the left and right end surfaces of each wall 2, 3, 4 with screws 14 so as to connect and fix each wall 2, 3, 4, and is a plate body having a shape substantially similar to the side surface shape of the main body 5; It consists of

After each wall 2, 3, 4 is formed, the frame 1 is assembled with these walls joined at joints 11, 12.
3 to fix each of these walls 2, 3, and 4. When the main body 5 is erected in its normal state in this fixed state as shown in Fig. 1, the portion of the frame 13 corresponding to the bottom wall 4 will bulge outward slightly due to the load of the top wall 2 or the back wall. . 15 is left and right frame 1
A support member lying with a length of 3.5 mm, and has coupling holes 17 at both left and right ends for screw coupling to coupling holes 22 of fixing pieces 16 extending inwardly from the left and right frames 13. A locking hole 18 is provided near and inward of this hole 17. Reference numeral 19 denotes a pinch-type straightening tool which is large enough to be operated with one hand, and when gripped with a grip 20, the pinch part 21 at the tip acts as a pinch as shown by the arrow. This clamping part 2
1 is inserted and locked into the locking hole 18, and the other clamping part 21 is locked on the outer surface of the frame 13, and by strongly grasping the grip parts 20, 20, the frame 13 is removed.
The bulge is corrected and both coupling holes 17 and 22 match. This operation is performed, for example, by screwing together the right coupling hole 17 of the support member 15 and the coupling hole 22 of the fixing piece 16 in advance, and then straightening the left end of the support member 15 with the straightening tool 19 as described above. Once they are connected, the assembly operation is accomplished. Therefore, the locking hole 18 may be provided only at one end of the support member 15.

The support member 15 supports the rear end of the bottom plate 23 provided at the lower part of the product storage chamber 9. The bottom plate 23 constitutes a part of the partition plate 10 described above, and the airflow passage 2
6 is also formed.

Note that when a plurality of open-side cases 1 are connected laterally, the side wall 6 is often not provided on the connected side.

(g) Effects of the invention According to the invention, the top wall, back wall, and bottom wall are made separately and connected to each other, and the frame that firmly holds the connections between these walls is made of a plate and bulges outward. However, the bulge in the frame can be easily corrected using the straightening tool, and the bulge in the left and right frames can be eliminated by the support member, allowing the frame to return to its normal shape. This eliminates disadvantages such as creating gaps due to the bulge of the frame and making it difficult to attach parts fixed to the frame even when the open show cases are connected laterally.

Further, since the support member can serve not only for straightening the frame but also for supporting the bottom plate, there is no need to provide a special member for straightening the frame.
