Description

  The present invention relates to a multistage open showcase, and more particularly to a mounting structure for a back panel of a product display room.

  The multistage open showcase is described in, for example, Patent Document 1, but its general structure is shown again in FIG. In FIG. 4, a product display chamber 3 whose front surface is opened by an inner box 2 made of a steel plate is partitioned inside a main body case 1 made of a heat insulating wall, and a cold air circulation ventilation path 4 is formed around the product display chamber 3. A cooler 5 and a blower fan 6 are installed in a lower space of the showcase body 1 that constitutes a part of the cool air circulation ventilation path 4. A rectifying body having a honeycomb structure is incorporated as a cold air outlet 7 at the upper end portion of the cold air circulation passage 4, and the lower end portion is configured as a cold air inlet 8. In the merchandise display room 3, merchandise shelves 9 are installed in multiple stages (four stages in the figure).

  In such an open showcase, when the blower fan 6 is operated, the airflow circulates in the circulation ventilation path 4 in the direction of the arrow, and the airflow blown out from the outlet 7 is air curtain on the open surface of the product storage chamber 3. 10 is formed, and the commodity storage chamber 3 is shut off from the outside air. This airflow passes through the cooler 5 and is cooled to cool a product (not shown) on the product shelf 9 while circulating as cold air. Although not illustrated, a large number of small holes are provided on the back surface of the inner box 2, and the cold air also flows into the cabinet through these small holes.

  Here, a shelf column 11 is fixed vertically in the main body case 1, and the product shelf 9 is hung on the shelf column 11 via a bracket 12. On the other hand, the inner box 2 includes an upper panel 13, a back panel 14, a deck pan 15, and the like, and the back panel 14 is attached to the shelf column 11.

FIG. 5 is an enlarged view showing a horizontal section of the shelf column portion of FIG. In FIG. 5, the shelf column 11 includes end columns 16 at both left and right ends and a central middle column 17, both of which are fixed to the main body case 1 with screws (not shown). The rear panel 14 is divided into left and right parts, and is attached to the front surface so as to cross the end pillar 16 and the middle pillar 17 respectively. In that case, a screw (tapping screw) 18 is screwed through a mounting hole penetrating the back panel 14 into a plurality of prepared holes formed in the shelf column 11 (end column 16 and middle column 17). It is fastened to the shelf column 11 by 18. A number of slit holes 19 for hanging the brackets 12 of the merchandise shelf 9 are arranged on the front surface of the shelf column 11 in the vertical direction.

  Conventionally, a back panel forming a product display room is attached to a shelf column with screws. For this reason, conventionally, the mounting of the back panel is very laborious, which increases the number of showcase assembly steps. Also, during maintenance at the installation site, it took time to attach and detach the rear panel, and if it was repeatedly attached and removed many times, the bottom hole of the shelf column widened, making it impossible to tighten.

  Therefore, an object of the present invention is to simplify the attachment / detachment of the back panel to / from the shelf column, to reduce the number of showcase assembly steps and to facilitate the on-site maintenance work.

  In order to solve the above-described problems, the present invention provides a product display room having a front surface opened inside a main body case made of a heat insulating wall, and product shelves are installed in multiple stages in the product display room. In the open showcase attached from the front to the shelf column supported by the main body case, the rear panel of the chamber is formed with dowels protruding from the left and right side surfaces of the back panel or the side surfaces of the shelf columns facing the left and right side surfaces, A recess corresponding to the dowel is formed on a side surface of the shelf column or a left and right side surface of the back panel, the back panel is pushed into the shelf column from the front, and the dowel is fitted into the recess to attach the back panel to the It is intended to be attached to a shelf column.

  According to the present invention, the back panel can be easily attached and removed without screwing by fitting one dowel of the back panel and the shelf column and the other recess to attach the back panel to the shelf column. In addition, the screw hole does not expand or the screw thread is not crushed by repeated attachment and detachment.

  1 to 3 show an embodiment of the present invention, FIG. 1 is a horizontal sectional view of a shelf column portion of an open showcase, FIG. 2 is a perspective view showing a dowel formed on a back panel, and FIG. 3 is a shelf column. It is a principal part enlarged view which shows the formed recessed part. In addition, the same code | symbol shall be used for the part corresponding to a prior art example. In FIG. 1, the shelf column 11 includes end columns 16 at the left and right ends and a center column 17 at the center, and the back panel 14 is divided into two on the left and right sides so that the front panel extends to the end column 16 and the center column 17, respectively. Is attached. Here, both ends of the back panel 14 are bent in an L shape, and vertically long dowels 14a shown in FIG. On the other hand, a concave portion 11a corresponding to the dowel 14a is formed on the side surface of the shelf column 11 (end column 16 and middle column 17) facing the left and right side surfaces of the back panel 14. In the case of FIG. 1, the recess 11 a is formed as a V-groove shown in FIG.

  In order to mount the back panel 14, the back panel 14 is pushed into the shelf column 11 as shown by the arrow in the left panel of FIG. 1, and the dowels 14a are elastically formed in the recesses 11a as shown in the right panel of FIG. Fit together. Thereby, the back panel 14 can be easily attached to the shelf column 11. Moreover, the attached back panel 14 can be easily removed by pulling forward. The recess 11a of the shelf column 11 can be a reverse dowel shown in FIG. 3B or a hole shown in FIG. In the illustrated embodiment, the dowel is formed on the back panel side and the recess is formed on the shelf column side. However, it is also possible to form the recess on the back panel side and form the dowel on the shelf column side. It is.

It is a horizontal sectional view of the shelf column portion of the open showcase showing the embodiment of the present invention. It is a perspective view which shows the dowel of the back panel in FIG. It is a perspective view which shows the various aspects of the recessed part formed in a shelf pillar. It is a longitudinal cross-sectional view which shows the general structure of an open showcase. It is a horizontal sectional view of a shelf column part of an open showcase showing a conventional example.
