Moreover, the frame 4 configured by combining the members is designed in advance so that the outer shape in plan view matches the space in which the corner-type heat insulating box 1 is arranged in the open showcase 2. .

  The front frame 40 extends in the left-right direction, and extends from the left end of the extended portion 40a, 40a ′ that is divided into two left and right at the substantially central portion, the right end of the right extended portion 40a, and the left extended portion 40a ′. Inclined portions 40 b and 40 b ′ extending so as to spread forward at a predetermined angle, and the left and right extending portions 40 a and 40 a ′ are connected by a connecting member 43. Yes. Similarly, the rear frame 41 also extends in the left-right direction, and extends from the left end of the extending portions 41a and 41a ′, which are divided into right and left at the substantially central portion, the right extending portion 41a, and the left extending portion 41a ′. Inclined portions 41 b and 41 b ′ extending so as to spread forward at a predetermined angle, and the left and right extending portions 41 a and 41 a ′ are connected by a connecting member 43. . Here, the predetermined angle is an angle at which the inclined portions 40b, 40b ′, 41b, 41b ′ are parallel to the extending direction of the adjacent straight cases 30, 30, and such inclined portions 40b, 40b ′, By providing 41b and 41b ', the position of the divided box bodies 11 and 13 can be adjusted accurately and easily.

  The connecting frames 42, 42,... Are formed to have the same length in the front-rear direction, and the two connecting frames 42, 42 are spaced apart from each other in parallel to the left and right and extend portions 40a, 40a ′. And the other two connecting frames 42, 42 are connected to the end portions of the inclined portions 40b, 40b ′ and the inclined portions 41b, 41b ′. It is fixed to connect each other.

Further, horizontal portions 40c and 40g of the front frame 40, which will be described later, and horizontal portions 41c and 41g of the rear frame 41 become parallel and horizontal, respectively. Moreover, since the frame 4 formed in this way has a structure that can be divided into left and right by removing the connecting members 43, 43, it can be easily transported.

  Further, as shown in FIG. 4, the front frame 40 is formed by bending a steel plate or the like, and in a side sectional view, the horizontal portion 40c, the vertical portion 40d bent downward from the horizontal portion 40c, and the vertical A bottom plate portion 40e that is bent horizontally from the portion 40d, a vertical portion 40f that is bent upward from the bottom plate portion 40e, and a horizontal portion 40g that is bent rearward from the vertical portion 40f. In addition, since the rear frame 41 also has substantially the same shape as the front frame 40 in the side sectional view, the description in the side sectional view of the rear frame 41 is omitted. In addition, each of the connecting frames 42, 42,... Is formed by bending a steel plate or the like so as to form a U shape in a sectional view (see FIG. 3). According to this, since each part of the front frame 40 and the rear frame 41 and the bent part of the connecting frames 42, 42,... Function as ribs, the bending rigidity and torsional rigidity of the frame body 4 are extremely strong. It has become. Further, since the front frame 40, the rear frame 41, and the connecting frames 42, 42,... Are formed by bending, the frame body 4 is inexpensive and lightweight.

  Further, as shown in FIGS. 3 and 4, an upright portion 44 as a guide portion that rises upward is formed at the rear end edge of the horizontal portion 41 g on the rear end side in the rear frame 41. Also, vertically extending plate members 45, 45 are disposed on the outer sides of the connecting frames 42, 42 fixed so as to connect the left and right ends of the front frame 40 and the rear frame 41, respectively. The upper end portions 45a and 45a of 45 and 45 project upward from the horizontal portions 40c and 40g of the front frame 40 and the horizontal portions 41c and 41g of the rear frame 41. In other words, on the upper side of the frame body 4, the left and right end sides and the rear end side are surrounded by the upper end portions 45 a and 45 a of the plate members 45 and 45 and the upright portion 44. The front frame 40 side is open.

  As shown in FIGS. 4 and 5, the right split box 13 has a right end surface 13f (specifically, an end surface formed by the front wall portion 13a, the bottom portion 13b, the rear wall portion 13c, and the heat insulating material 34). While being in contact with the side surface of the upper end portion 45 a of the right plate member 45, the rear surface 13 e of the rear wall portion 13 c is in contact with the upright portion 44 of the rear frame 41. As a result, the right divided box 13 is guided by the upper end portion 45 a and the upright portion 44 of the plate member 45 and is positioned at a specified position of the right divided box 13. The specified position of the right divided box 13 is the position (position) of the right divided box 13 with respect to the frame 4, and in a state where the right divided box 13 is positioned at the specified position, The right end surface 13f of the right split box 13 is orthogonal to the longitudinal direction of the straight heat insulating box 3 adjacent to the right. That is, the angle of the right split box 13 is determined to be an optimum angle that can be connected in alignment with the adjacent straight heat insulating box 3. Since the left divided box 11 is positioned in the same manner as the right divided box 13, the description of the positioning mode of the left divided box 11 is omitted.

  In the central divided box 12, the rear surface 12 e of the rear wall portion 12 c is in contact with the upright portion 44 of the rear frame 41. As a result, the central divided box 12 is guided by the upright portion 44 and is positioned at the specified position of the central divided box 12. The specified position of the central divided box 12 is the position (position) of the central divided box 12 with respect to the frame 4, and when the central divided box 12 is positioned at the specified position, The angle of the central divided box 12 with respect to the adjacent left and right divided boxes 11 and 13 is also determined. Therefore, when the divided box bodies 11, 12, and 13 are positioned at the specified positions, the outer dimensions of the divided box bodies 11, 12, and 13 are aligned with the outer shape of the frame body 4. Further, in the central divided box 12, the central divided box 12 is guided to the upright portion 44 and does not interfere with the left and right divided boxes 11 and 13, so that it can be located at any position in the left-right direction. It becomes the specified position.

  In this way, the divided box bodies 11, 12, and 13 are guided and positioned at the respective specified positions by the upright portion 44 and the upper end portions 45a and 45a of the plate members 45 and 45, so that the divided box bodies 11 and 12 are positioned. , 13 is extremely easy to position.

  The corner-type heat insulation box 1 is divided into the upper surfaces of the horizontal portions 40c and 40g of the front frame 40 and the horizontal portions 41c and 41g of the rear frame 41 described above. In contrast, the divided box bodies 11, 12, and 13 are fixed by a not-shown bolt or the like and fixed by a plate-like connecting material or the like (not shown). As described above, the corner-type heat insulating box 1 has a structure in which the frame 4 is fixed below the divided boxes 11, 12, 13. The frame 4 does not affect the accessory parts for the 11, 12, 13 and the like. Therefore, the corner type heat insulation box 1 can be configured by using the divided boxes 11, 12, 13 as they are without performing special processing or the like on the divided boxes 11, 12, 13. Furthermore, since the frame body 4 reinforces the divided box bodies 11, 12, and 13, the rigidity is high with respect to the external force in the bending direction or the twisting direction.

  As described above, the corner-type heat insulating box 1 is composed of the divided boxes 11, 12, 13 and the frame 4, and each divided box 11, 12, 13 is placed at a specified position using the frame 4. Since it can position, the corner-type heat insulation box 1 with high dimensional accuracy can be formed easily. Therefore, for example, when attaching a ready-made decorative board formed in a predetermined dimension to the front surfaces 11d, 12d, and 13d of the front wall portions 11a, 12a, and 13a, which are exposed surfaces of the corner-type heat insulating box 1, It is possible to attach it with a good appearance without causing any problems (see particularly FIG. 5).

  Further, since the left and right divided box bodies 11 and 13 are orthogonal to the longitudinal direction of the adjacent straight heat insulating box bodies 3 and 3, the left and right end faces 11 f and 13 f are front surfaces 11 d and 13 a of the front wall portions 11 a and 13 a. 13d can be flush with the front surfaces 3d and 3d of the front wall portions 3a and 3a of the straight heat insulating boxes 3 and 3 (see FIG. 1). Thereby, the said decorative board can be attached to the exposed surface of the corner type heat insulation box 1 and the straight type heat insulation boxes 3, 3, for example.

  In addition, the frame 4 has an outer shape in plan view that matches the space in which the corner-type heat insulating box 1 is arranged in the open showcase 2, so that the divided box while visually recognizing the outer shape of the frame 4 The bodies 11, 12, 13 can be easily positioned at the specified positions. Moreover, the frame 4 does not protrude outside the divided boxes 11, 12, 13, and the compact corner-type heat insulating box 1 can be formed.

  As shown in FIGS. 3 and 4, the corner base legs 14, 14,... Have leg portions 14a that extend in contact with the floor surface, and both ends of the leg portions 14a are erected upward. Parts 14b, 14b, and mounting parts 14c, 14c provided on the upper ends of the standing parts 14b, 14b, respectively, on which the frame body 4 is placed. The mounting portions 14c and 14c are disposed on the lower surfaces of the bottom plate portion 40e of the front frame 40 and the bottom plate portion 41e of the rear frame 41, and are fixed by bolts or the like. Further, the lower side of the plate members 45, 45 described above is detachably fixed to the sides of the standing portions 14 b, 14 b disposed at the left and right ends of the frame body 4 with bolts or the like. As described above, since the corner base legs 14, 14,... Are attached to the frame 4 having a frame structure having rigidity higher than that of the connected divided boxes 11, 12, 13, the corner-type heat insulating box 1 is stable. Can be supported.

  The height dimension of the corner base leg 14 is larger than the height dimension of the straight base leg 31 described above, and is a frame interposed between the divided box 13 and the mounting portions 14c, 14c of the corner base leg 14. It is formed shorter by the thickness of the body 4. According to this, the height position of the lower surface of the bottom 3b of the straight type heat insulation box 3 provided with the straight base legs 31, 31,... And the corner type heat insulation box provided with the corner base legs 14, 14,.
