After this type of showcase is installed in a supermarket, convenience store, or the like, it may be planned to change the layout of the equipment in the area where the showcase is installed, or to relocate the showcase to another area. In such cases, the original width of the showcase may be inconvenient, and the showcase manager or the like may request that the showcase be modified or remodeled to a narrower width than the original. In such a case, even if it were permitted to remove the front door and door storage unit from the case body, simply removing the front door and door storage unit would leave the side of the case body exposed to the outside.

Therefore, the present invention aims to provide a showcase that can be easily reassembled into a showcase that does not have a door or door storage section while closing off the sides of the case body by reusing showcase components.

According to one aspect of the present invention, there is provided a showcase having a case body with an open front, a door having one side supported rotatably around an axis extending in the vertical direction and provided so as to open and close at least a portion of the front opening of the case body, and a door storage section arranged on the side of the case body and capable of storing the door, and in which merchandise is displayed in an area inside the case body. This showcase includes a side plate section having a side plate covering the door storage section from the side opposite the case body in the door storage section, and a mounting tool for mounting the side plate section to the door storage section. The mounting tool is screwed to the door storage section. The case body has a plurality of spare holes formed at intervals that correspond to the intervals of a plurality of holes formed in the door storage section for screwing the mounting tool.

The showcase according to one aspect of the present invention has a side plate portion having a side plate covering the door storage portion from the opposite side of the case body in the door storage portion, and a mounting tool for mounting the side plate portion to the door storage portion. The mounting tool is screwed to the door storage portion, and the case body has a plurality of spare holes formed at intervals corresponding to the intervals of the plurality of holes for screwing the mounting tool formed in the door storage portion. Therefore, when the showcase is used as an open showcase without the door and the door storage portion, the door and the door storage portion are removed from the case body, and the side plate portion is removed from the door storage portion together with the mounting tool. The removed side plate portion is then easily screwed to the case body via the mounting tool using the plurality of spare holes formed in the case body. As a result, the side of the case body is blocked by the side plate portion, which is a showcase component (i.e., a component of the showcase). As a result, the showcase having the door and the door storage section can be easily reassembled into an open showcase that does not have the door or the door storage section.

In this way, it is possible to provide a showcase that can be easily reassembled into an open showcase that does not have a door or door storage section while still closing off the sides of the case body by reusing the showcase components.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a perspective view of a showcase 100 according to an embodiment of the present invention, and Fig. 2 is a cross-sectional view of the showcase 100. The showcase 100 is a refrigerated showcase installed in, for example, a supermarket or a convenience store. The showcase 100 may be a showcase for freezing or warming. In Figs. 1 and 2, a door 4, which will be described later, is shown in a closed state.

In this embodiment, the showcase 100 has a case body 1 with a U-shaped cross-section that is open at the front (customer side, display side, sales floor side), an installation stand 2 that is attached to the bottom surface of the case body 1 and supports the case body 1, a side unit 3 that is disposed on the side of the case body 1 and covers the side opening of the case body 1, and a door 4 that is provided so as to be able to open and close the front opening of the case body 1. Note that in this embodiment, front and back, left and right, and top and bottom are defined when viewed from the front as seen toward the front of the showcase 100.

The case body 1 is composed of an insulating member 11 having a U-shaped cross section with an opening at the front, an inner panel 12 arranged inwardly and spaced apart from the inner surface of the insulating member 11, and an outer panel 13 arranged on the outer surface side of the insulating member 11.

The inner panel 12 is composed of a top plate portion 12a, a bottom plate portion 12b that faces the top plate portion 12a below the top plate portion 12a, and a back plate portion 12c that connects the rear end portion of the top plate portion 12a to the rear end portion of the bottom plate portion 12b. Each plate portion (12a, 12b, 12c) is made of a thin plate material that is rectangular in plan view.

The outer panel 13 is composed of a top plate portion 13a, a back plate portion 13b, and a front plate portion 13c. Each plate portion (13a, 13b, 13c) is made of a thin plate material that is rectangular in plan view. The top plate portion 13a is located above the top plate portion 12a of the inner panel 12 and is arranged to cover the upper surface of the corresponding portion of the insulating member 11. The back plate portion 13b is arranged to cover the entire back surface of the insulating member 11, with a predetermined distance from the back surface of the insulating member 11. The front plate portion 13c is arranged to cover the front surface of the insulating member 11 at the front side and the lower end side of the case body 1.

The front of the case body 1 is open, and the front opening of the case body 1 can be opened and closed by a door 4. A side unit 3 is attached to each of the left and right sides of the case body 1. The inner panel 12 of the case body 1 and the left and right side units 3, 3 form a product display room 5 that is open to the front.

In the product display room 5, multiple (here, five) product display shelves 6 for placing (displaying) products are provided at intervals in the vertical direction. The product display shelves 6 are detachably attached to the back panel portion 12c of the inner panel 12. In this way, the showcase 100 displays products in the product display room 5, which is the area inside the case body 1.

In this embodiment, an air duct is formed mainly by the inner surface of the heat insulating member 11 and the outer surface of the inner panel 12. An evaporator, a blower for circulating cold air, and the like are housed in this air duct. The circulation of cold air by the blower for circulating cold air is performed through an outlet 7 formed in the front end portion of the top plate portion 12a of the inner panel 12 and an inlet 8 formed in the bottom plate portion 12b of the inner panel 12. As shown by the dotted arrow in FIG. 2, the flow of cold air from the outlet 7 to the inlet 8 forms an air curtain of cold air at the front opening of the product display room 5, and part of the cold air of this air curtain is circulated within the product display room 5 to cool the product display room 5.

The installation stand 2 is formed in a box shape, and a machine room is formed inside in which the compressor, condenser, condenser blower, etc. are arranged. The compressor and condenser, together with the evaporator described above, form a refrigeration circuit. A lower front panel 21 is attached to the front of the installation stand 2, and lower side panels 22 are attached to the left and right sides of the installation stand 2. The lower front panel 21 has slits for ventilation in the machine room. The lower side panels 22 are provided so as to cover the sides of the installation stand 2. Although not particularly limited, the lower side panel 22 protrudes above the top surface of the installation stand 2, and the portion of the lower side panel 22 that protrudes above the top surface of the installation stand 2 covers the lower end portion of the side unit 3.

The side units 3 function to cooperate with the case body 1 to form a product display room 5 with a front opening. In this embodiment, the side units 3 are disposed on the left and right sides of the case body 1, and are attached to the left and right sides of the case body 1, respectively. The left side unit 3 is referred to as the left side unit 3L, and the right side unit 3 is referred to as the right side unit 3R. The structures of the left side unit 3L and the right side unit 3R are identical except that they are symmetrical. The detailed structure of each side unit 3 will be explained later.

Figure 3 is a top view of the showcase 100, and Figure 4 is a perspective view of the showcase 100 in a state different from that shown in Figure 1 (door retracted state). Figure 5 is an enlarged top view of the front corner of the showcase 100 in the state shown in Figure 4.

The door 4 has one side (specifically, one side extending in the vertical direction) that is supported rotatably around the vertically extending shaft 313b (see FIG. 3, see FIG. 8 to FIG. 12 for details) that is provided so as to be able to open and close at least a part of the front opening of the case body 1. In other words, the door 4 is provided so as to be able to open and close the front opening of the product display room 5 that is partitioned by the case body 1 and the side unit 3. In this embodiment, the doors 4 are provided on both sides of the width direction (left and right direction) of the front opening of the case body 1, and the left door 4 and the right door 4 form a double door. In other words, the left door 4 is a left-opening door whose left side is supported rotatably around the shaft 313b, and opens and closes the left half of the front opening of the case body 1. The right door 4 is a right-opening door whose right side is supported rotatably around the shaft 313b, and opens and closes the right half of the front opening of the case body 1.

In this embodiment, each door 4 has as its main component a rectangular door panel 4a in plan view, made of a transparent plate such as a glass plate through which the area inside the case body 1 (inside the product display room 5) can be seen. The transparent plate may have a multi-layer structure with a hollow layer to improve thermal insulation. The edges of the door panel 4a are protected by a protective frame 4b. Note that each door panel 4a may also be an opaque thermal insulation panel.

As shown by the dashed lines in Figure 3, each door 4 is configured such that, for example, when it is opened to approximately 90 degrees in the opening direction, it is prevented from rotating any further. In this manner, the maximum open state is hereinafter referred to as the fully open state. In the fully open state, each door 4 is in a position extending in the front-to-rear direction approximately perpendicular to the front surface of the case body 1 (in other words, in a position parallel to the side surface of the case body 1).

As described in detail below, the doors 4 are configured to be stored in the side units 3 by sliding each door 4 backward when it is fully open (see FIG. 4). In more detail, the free end side of the door 4 stored in the side unit 3 (i.e., the side opposite to the side of the door 4 that is supported so as to be rotatable) protrudes forward from the front surface of the case body 1 as shown in FIG. 5.

Next, the side units 3 will be described in detail. Fig. 6 is an exploded perspective view of the showcase 100, and Fig. 7 is an exploded perspective view of each side unit 3. Fig. 8 is an oblique view of the door storage section 31 (described later) of the side unit 3 (right side unit 3R in the figure).

The side units 3 are attached to the left and right sides of the case body 1. With the side units 3 attached to the case body 1, the lower side panels 22 are attached to the installation stand 2 so as to cover the sides of the installation stand 2 and the sides of the lower end portions of the side units 3 (see FIG. 6).

The side unit 3 is configured to include a door storage section 31 that is arranged to the side of the case body 1 and can store the door 4 in a fully open state, a side plate section 32 that has a side plate 321 that covers the door storage section 31 from the side opposite the case body 1, and a mounting fixture 33 for mounting the side plate section 32 to the door storage section 31 (see Figures 7 and 8).

In this embodiment, the side units 3 are arranged on both the left and right sides of the case body 1 as described above. Therefore, the door storage sections 31 are arranged on both the left and right sides of the case body 1, and the side plate sections 32 are provided on the left side of the left door storage section 31 (i.e., the outer surface side of the left door storage section 31) and the right side of the right door storage section 31 (i.e., the outer surface side of the right door storage section 31). The mounting fixtures 33 are provided for both the left side plate section 32 and the right side plate section 32.

In this embodiment, a handle 9 for user operation is attached to the side of the free end of the door 4 housed in the side unit 3. As shown in FIG. 5, the handle 9 has a door swing prevention portion 9a located on the outside of the front end portion of the outer surface of the side plate portion 32 (more specifically, the side surface of the side plate portion 32 on the door storage portion 31 side) when the door 4 is housed in the door storage portion 31. Specifically, the handle 9 is made of a thin plate material, and has a protruding portion 9b that extends in the vertical direction along the side of the free end of the door 4 (protective frame 4b) housed in the door storage portion 31 and protrudes toward the side plate portion 32. The user can operate the door 4 by hooking a finger or the like on the protruding portion 9b. The door swing prevention portion 9a is made of a thin plate material formed integrally with the protruding portion 9b, and is formed to protrude approximately backward from both ends of the protruding portion 9b in the vertical direction.

Figures 9 and 10 are side views of the door storage section 31 (specifically, the door storage section 31 of the right side unit 3R). Specifically, Figure 9 is a plan view (inner side view) of the door storage section 31 viewed from the side of the case body 1 side of the door storage section 31 (in other words, the inner side of the door storage section 31), and Figure 10 is a plan view (outer side view) of the door storage section 31 viewed from the side of the side plate section 32 side of the door storage section 31 (in other words, the outer side of the door storage section 31).

Specifically, the door storage section 31 has an upper frame 311a, a lower frame 311b, and a rear frame 311c, each of which has an L-shaped cross section, and an upper insulation box 311d and a lower insulation box 311e. The door storage section 31 includes a frame body 311 consisting of the frames and insulation boxes (311a to 311e) as its main structure. This frame body 311 has an overall cross section that is roughly U-shaped with an open front. The inner areas of the frames (311a to 311c) in the door storage section 31 are open in the left and right directions, and communicate with the product display chamber 5 when the side unit 3 is attached to the case body 1. The openings on the opposite side of the product display chamber 5 in the inner areas of the frames (311a to 311c) are closed by the side panel 32.

The upper frame 311a extends in the front-rear direction along the upper portion of the side of the case body 1. The lower frame 311b extends parallel to the upper frame 311a along the lower portion of the side of the case body 1. The rear frame 311c connects the rear end of the upper frame 311a to the rear end of the lower frame 311b, and has a rear frame extension 311c1 that extends downward beyond the lower frame 311b.

The upper insulation box 311d has an insulating structure, is fixed to the upper frame 311a so as to cover the upper frame 311a from above, and has an upper surface that forms the upper surface of the side unit 3. The lower insulation box 311e has an insulating structure and is reinforced inside. The lower insulation box 311e is fixed to the lower surface of the lower frame 311b and is fixed to the rear frame extension 311c1 of the rear frame 311c.

In this embodiment, the door storage section 31 has a pair of upper and lower slide sections 312, 312 for supporting the door 4 so that it can slide in the front and rear directions, a pair of upper and lower door support sections 313, 313 for supporting the door 4 so that it can rotate freely, and a movable support section 314.

Each slide section 312 has a fixed rail 312a fixed to the frame body 311 of the door storage section 31 and a movable bracket 312b connected to the fixed rail 312a so as to be slidable in the forward and backward directions along the fixed rail 312a.

The upper fixed rail 312a is fixed to the surface of the upper frame 311a facing the side plate 32 and extends over the entire upper frame 311a. The lower fixed rail 312a is fixed to the surface of the lower frame 311b facing the side plate 32 and extends over the entire lower frame 311b.

Each movable bracket 312b has an L-shaped cross-sectional shape and extends in the front-rear direction. In the figure, the upper movable bracket 312b is arranged to surround part of the surface of the upper fixed rail 312a facing the side plate portion 32 and part of the bottom surface of the upper fixed rail 312a. The lower movable bracket 312b is arranged to surround part of the surface of the lower fixed rail 312a facing the side plate portion 32 and part of the top surface of the lower fixed rail 312a.

Each door support section 313 has a support plate 313a made of a thin plate material that is fixed to the corresponding slide section 312, and a shaft section 313b that extends in the vertical direction to support the door 4 so that it can rotate freely.

The upper support plate 313a is fixed to the lower surface of the upper movable bracket 312b. The lower support plate 313a is fixed to the upper surface of the lower movable bracket 312b.

The upper shaft portion 313b is fixed to the front end portion of the underside of the upper support plate 313a. The lower shaft portion 313b is fixed to the front end portion of the upper surface of the lower support plate 313a. An upper bracket 4c for connecting to the shaft portion 313b of the upper door support portion 313 is attached to the upper end portion of one side of the door 4, and a lower bracket 4d for connecting to the shaft portion 313b of the lower door support portion 313 is attached to the lower end portion of one side of the door 4.

The movable support 314 is a support member for connecting the upper door support 313 and the lower door support 313. The movable support 314 has, for example, a U-shaped cross-sectional shape with an opening on the side opposite to the case body 1, and extends from the upper support plate 313a to the lower support plate 313a. The support plate 313a of the upper door support 313 is attached to the upper end of the movable support 314, and the support plate 313a of the lower door support 313 is attached to the lower end of the movable support 314. As a result, the pair of upper and lower door support parts 313, 313, the movable support 314, and the door 4 are integrated, and these (313, 313, 314, 4) can slide together in the front-rear direction by the pair of upper and lower slide parts 312 within the side unit 3.

A rotation stopper portion 315 is attached to each of the upper and lower end portions of the front end surface of the movable support portion 314 to determine the maximum rotation angle of the door 4 in the opening direction. As described above, when each door 4 is opened approximately 90° in the opening direction as shown by the dashed line in Figure 3, the end face of one side of the door 4 abuts against the rotation stopper portion 315, thereby preventing the door 4 from rotating further in the opening direction.

In this embodiment, the door storage section 31 further includes a rear stopper piece 316, a front stopper piece 317, a door forward movement suppression section 318, and a door rearward movement prevention mechanism 319.

Figures 11 to 13 are conceptual diagrams for explaining the door forward movement suppression section 318 and the door rearward movement prevention mechanism 319. Figure 11 shows a state in which the forward movement of the door 4 is suppressed at the rearward end position, and Figure 12 shows a state in which the rearward movement of the door 4 is prevented at the forward end position. Figure 13 is a partially enlarged perspective view of the door rearward movement prevention mechanism 319, with Figure 13(a) being an enlarged perspective view of the upper side and Figure 13(b) being an enlarged perspective view of the lower side.

The rear stopper piece 316 is a member for determining the rear end position of the door 4 in the door storage section 31. The rear stopper piece 316 is provided at a predetermined position on the rear end side in the front-rear direction of each of the upper fixed rail 312a and the lower fixed rail 312a. Specifically, the upper rear stopper piece 316 is fixed to the upper fixed rail 312a so as to protrude downward from the lower surface of the upper fixed rail 312a, and the lower rear stopper piece 316 is fixed to the upper fixed rail 312a so as to protrude upward from the upper surface of the lower fixed rail 312a. In this embodiment, the upper end of the upper slide part 319c of the door rear movement prevention mechanism 319, which will be described later, abuts against the upper rear stopper piece 316, and the lower end of the lower slide part 319d of the door rear movement prevention mechanism 319, which will be described later, abuts against the lower rear stopper piece 316. This prevents the door 4, which retracts together with the movable support 314, from moving further back, and the position of the door 4 at this time becomes the retracted end position, with the door 4 being stored in the door storage section 31.

In this embodiment, when the door 4 is stored in the door storage section 31, as shown in Figures 4 and 5, the door anti-sway portion 9a of the handle 9 of the door 4 is in contact with the front end portion of the outer surface of the side plate portion 32. Therefore, in this state, the door 4 is prevented from rotating in the closing direction by the door anti-sway portion 9a, and the door 4 is prevented from swinging within the door storage section 31.

The front stopper piece 317 is a member for determining the forward end position of the door 4. The front stopper piece 317 is provided so as to be located near the front end surface of the upper fixed rail 312a and near the front end surface of the lower fixed rail 312a. Specifically, the upper front stopper piece 317 is fixed to the front end of the upper frame 311a and has a surface facing a part of the front end surface of the upper fixed rail 312a, and the lower front stopper piece 317 is fixed to the front end of the lower frame 311b and has a surface facing a part of the front end surface of the lower fixed rail 312a. In this embodiment, the front end of the upper movable bracket 312b abuts against the upper front stopper piece 317, and the front end of the lower movable bracket 312b abuts against the lower front stopper piece 317. This prevents the door 4, which advances together with the movable support part 314, from advancing any further, and the position of the door 4 at this time becomes the forward end position.

The door forward movement suppression part 318 suppresses the door 4 stored in the door storage part 31 from sliding forward unintentionally. Specifically, the door forward movement suppression part 318 is made of a magnet attached to a predetermined position (the upper end part of the end face in the figure) on the end face facing the movable support part 314 in the rear frame 311c of the frame body 311. An iron suction plate 318a is attached to the end face facing the door forward movement suppression part 318 in the movable support part 314, and the suction plate 318a is attracted to the door forward movement suppression part 318 by magnetic force, thereby suppressing the door 4 from sliding forward unintentionally. The door forward movement suppression part 318 is not limited to a magnet. For example, a bracket that can clamp the rear end of the retracted movable support part 314 and engage with the movable support part 314 may be provided at the front end of the rear frame 311c as the door forward movement suppression part 318, or a bracket that can clamp the front end of the rear frame 311c and engage with the rear frame 311c may be provided at the rear end of the movable support part 314 as the door forward movement suppression part 318.

The rearward door movement prevention mechanism 319 is a mechanism that can be switched between a rearward movement prevention state (see Figures 12 and 13) in which the door 4 at the forward end position is prevented from moving rearward, and a release state in which this rearward movement prevention state is released (i.e., a state in which rearward movement is permitted).

In this embodiment, the rear door movement prevention mechanism 319 is configured with a locking claw 319a, a through hole portion 319b (see FIG. 13), an upper slide portion 319c, and a lower slide portion 319d.

The locking claw 319a is a member for preventing the door 4 at the forward end position from moving backward. The locking claw 319a is provided at a predetermined position on the front end side in the front-rear direction of each of the upper fixed rail 312a and the lower fixed rail 312a. Specifically, the upper locking claw 319a is fixed to the upper fixed rail 312a so as to protrude downward from the lower surface of the upper fixed rail 312a, and the lower locking claw 319a is fixed to the upper fixed rail 312a so as to protrude upward from the upper surface of the lower fixed rail 312a. The upper locking claw 319a has an inclined surface that is inclined so as to move away from the lower surface of the upper fixed rail 312a as it moves forward, a flat surface that extends forward from the front end of the inclined surface, and a front end surface that extends from the front end of the flat surface toward the lower surface side of the upper fixed rail 312a. The lower locking claw 319a has an inclined surface that slopes away from the upper surface of the lower fixed rail 312a as it moves forward, a flat surface that extends forward from the front end of this inclined surface, and a front end surface that extends from the front end of this flat surface toward the upper surface of the lower fixed rail 312a.

The through-hole portion 319b is a hole opened in each support plate 313a and each movable bracket 312b (see FIG. 13). Specifically, the upper through-hole portion 319b is opened to include a portion corresponding to the upper end of the upper slide portion 319c in the upper support plate 313a and the movable bracket 312b (see FIG. 13(a)). The lower through-hole portion 319b is opened to include a portion corresponding to the lower end of the lower slide portion 319d in the lower support plate 313a and the movable bracket 312b (see FIG. 13(b)).

The upper slide portion 319c extends vertically along the upper half of the side surface of the movable support portion 314, and the lower slide portion 319d extends vertically along the lower half of the side surface of the movable support portion 314, aligning its axis with the upper slide portion 319c. The upper slide portion 319c and the lower slide portion 319d are guided so as to be able to slide vertically along the side surface of the movable support portion 314. The upper slide portion 319c is biased upward by the upper spring portion 319e made of a tension coil spring, and in the initial state, its upper end portion passes through the upper through-hole portion 319b. The lower slide portion 319d is biased downward by its own weight and the lower spring portion 319f made of a tension coil spring, and in the initial state, its lower end portion passes through the lower through-hole portion 319b. An operating part 319g is provided at the lower end of the upper slide part 319c and at the upper end of the lower slide part 319d (see Figure 9).

In this embodiment, the upper end of the upper slide portion 319c abuts against the front end surface of the upper lock claw 319a, and the lower end of the lower slide portion 319d abuts against the front end surface of the lower lock claw 319a, thereby preventing the door 4 from moving backward at the forward end position. At this time, the door rearward movement prevention mechanism 319 is in a rearward movement prevention state (see Figures 12 and 13). Then, when the pair of upper and lower operating parts 319g, 319g are operated by the user, the upper slide portion 319c moves downward and the lower slide portion 319d moves upward, the rearward movement prevention state is released and the door 4 is allowed to move backward (backward). As a result, the door rearward movement prevention mechanism 319 switches from the rearward movement prevention state to the released state. In addition, in the process of the door 4 being pulled out from the rear end position to the forward end position, the upper end of the upper slide portion 319c abuts against the inclined surface of the upper locking claw 319a, but the upper slide portion 319c moves downward against the biasing force of the upper spring portion 319e, and the lower slide portion 319d moves upward against the biasing force of the lower spring portion 319f. This makes it possible to pull out the door 4 to the forward end position.

Returning to FIG. 7, the side panel portion 32 has the above-mentioned side panel 321 and a protective cover 322. In this embodiment, the side panel 321 is a transparent panel such as a glass panel that allows the inner area of the case body 1 (inside the product display room 5) to be seen through, similar to the door panel 4a of the door 4, and is arranged to cover the outer surface of the door storage portion 31. As the transparent panel, a panel having a multi-layer structure with a hollow layer may be used to improve heat insulation. In addition, for example, an opaque film 321a is attached to the upper edge side, front edge side, and rear edge side of the surface of the side panel 321. The protective cover 322 is a member that protects the upper edge and front edge parts of the side panel 321. In this embodiment, the door storage portion 31 to which the side panel portion 32 is attached has a structure made of the frame body 311 as described above, so the side panel portion 32 does not need to have the strength as a structure. Therefore, it is possible to adopt a glass panel as the side panel 321 of the side panel portion 32. Additionally, opaque heat-insulating panels may be used for each side panel 321.

The mounting fixture 33 is a member for attaching the side plate portion 32 to the door storage portion 31, and is screwed to the door storage portion 31. In this embodiment, the mounting fixture 33 is provided for screwing to the upper end portion of the door storage portion 31, screwing to the rear end portion of the door storage portion 31, and screwing to the lower end portion of the door storage portion 31. In the following, the mounting fixture 33 for screwing to the upper end portion of the door storage portion 31 is called the upper mounting fixture 34, the mounting fixture 33 for screwing to the rear end portion of the door storage portion 31 is called the rear mounting fixture 35, and the mounting fixture 33 for screwing to the lower end portion of the door storage portion 31 is called the lower mounting fixture 36. In each figure, the screws for fastening each part, including the screws for screwing the side plate portion 32 to the door storage portion 31, are omitted from the illustration.

Figures 14 to 18 are conceptual diagrams for explaining each mounting fixture 33. Figure 14 is a top view of the door storage section 31 for explaining each mounting fixture 33. Figure 15 is an enlarged view of part A shown in Figure 14. Figure 16 is a rear view of the door storage section 31. Figure 17 is an enlarged view of part B shown in Figure 16. Figure 18 is a diagram for explaining the rear mounting fixture 35 and the lower mounting fixture 36, Figure 18(a) is an enlarged perspective view of the lower end side of the door storage section 31, and Figure 18(b) is an outer side view of the lower end side part of the door storage section 31. In Figures 14(a), 16(a) and 18(a), each mounting fixture 33 is shown by a solid line, and in Figures 14(b), 16(b) and 18(b), each mounting fixture 33 is shown by a dashed line.

Here, a number of holes 31a are formed in the parts of the door storage section 31 that correspond to each mounting fixture 33 (34, 35, 36) for screwing to the corresponding mounting fixture 33 (34, 35, 36).

Specifically, the upper mounting fixture 34 is a member for attaching the upper edge of the side plate portion 32 to the upper end portion of the door storage portion 31. Specifically, the upper mounting fixture 34 is screwed to the upper surface of the upper insulation box 311d of the door storage portion 31 (see FIG. 14). The upper mounting fixture 34 is formed, for example, in a rectangular shape when viewed from above. One long side of the upper mounting fixture 34 protrudes inward from the inner surface of the door storage portion 31, and the other long side of the upper mounting fixture 34 protrudes outward from the outer surface of the door storage portion 31. A plurality of first upper through holes 34a (five in the figure) for threading are opened at intervals in the front-rear direction in the center of the width direction of the upper mounting fixture 34, and a second upper through hole 34b for threading is opened in the other long side of the upper mounting fixture 34 (see FIG. 14(a)).

The upper surface of the upper insulation box 311d of the door storage section 31 has a plurality of holes 31a, each of which is spaced at intervals corresponding to the intervals of the first upper through holes 34a. A plurality of first holes 31a1 (e.g., screw holes (female threads)) for screwing to the upper mounting fixture 34 (five in the figure) are formed as holes 31a (see FIG. 14(b)). The screws inserted into each first upper through hole 34a screw into the corresponding first hole 31a1 in the upper insulation box 311d, and the screws inserted into the second upper through holes 34b screw into the upper edge portion of the protective cover 322 (see FIG. 7) of the side plate section 32, thereby fixing the upper edge portion of the side plate section 32 to the upper insulation box 311d of the door storage section 31 via the upper mounting fixture 34.

In this embodiment, multiple (five in the figure) third upper through holes 34c for threading are opened in the one long side portion of the upper mounting fixture 34 at intervals that match the intervals of the multiple first upper through holes 34a and at the same positions in the front-to-rear direction. The purpose of these third upper through holes 34c will be explained later.

The rear attachment 35 is a member for attaching the rear edge of the side plate 32 in the front-rear direction to the rear end of the door storage section 31. Specifically, the rear attachment 35 is screwed to the rear frame 311c of the frame body 311 (see Figs. 14 to 17). The rear attachment 35 has, for example, a side plate clamping section 351 that has a U-shaped cross section that can accommodate and clamp the rear edge of the side plate 321 of the side plate section 32 and extends in the vertical direction, and an extension section 352 that extends from the tip of the side wall of the side plate clamping section 351 on the inner surface side of the door storage section 31 to the inner surface side of the door storage section 31. The extension section 352 of the rear attachment 35 has multiple (three in the figure) rear through holes 35a (e.g., long holes) for threading that are spaced apart in the vertical direction (see Fig. 16(a)).

The rear frame 311c of the door storage section 31 has a plurality of holes 31a at intervals that match the intervals of the rear through-holes 35a, and a plurality of (three in the figure) second holes 31a2 (e.g., screw holes (female threads)) for screwing to the rear mounting fixture 35 are formed as the plurality of holes 31a (see FIG. 16(b)). The screws inserted into each rear through-hole 35a screw into the corresponding second holes 31a2 in the rear frame 311c, and the side plate clamping portion 351 of the rear mounting fixture 35 clamps the rear edge of the side plate 321, so that the rear edge of the side plate portion 32 is fixed to the rear frame 311c of the door storage section 31 via the rear mounting fixture 35.

The lower mounting fixture 36 is a member for mounting the lower end of the side plate portion 32 to the lower end portion of the door storage portion 31. Specifically, the lower mounting fixture 36 is screwed to the side of the lower insulation box 311e of the side unit 3 (see Figures 16 to 18). The lower mounting fixture 36 has, for example, a first member 361 that supports the lower edge of the side plate 321 of the side plate portion 32, and a second member 362 for screwing the first member 361 to the side of the lower insulation box 311e of the door storage portion 31 (see Figure 17). The first member 361 and the second member 362 each have an L-shaped cross-sectional shape and extend in the front-rear direction. The first member 361 consists of a first vertical portion 361a that faces the side of the lower insulation box 311e at a distance and extends in the front-rear direction, and a first horizontal portion 361b that extends from the lower edge of the first vertical portion 361a toward the lower insulation box 311e. The second member 362 is composed of a second vertical portion 362a that extends in the front-rear direction along the side of the lower insulation box 311e, and a second horizontal portion 362b that is fixed to the upper surface of the first horizontal portion 361b of the first member 361. The second member 362 of the lower mounting fixture 36 has multiple (three in the figure) lower through holes 36a for threading that are spaced apart in the front-rear direction (see FIG. 18(a)).

Then, on the side of the lower insulation box 311e of the door storage section 31, a plurality of third holes 31a3 (e.g., screw holes (female threads)) for screwing to the lower mounting fixture 36 are formed as a plurality of holes 31a at intervals that match the intervals of the plurality of lower through holes 36a (see FIG. 18(b)). The screws inserted into each lower through hole 36a screw into the corresponding third holes 31a3 in the lower insulation box 311e, and the first member 361 of the lower mounting fixture 36 supports the lower edge of the side plate 321, so that the lower edge of the side plate portion 32 is fixed to the lower insulation box 311e of the door storage section 31 via the lower mounting fixture 36.

The side unit 3, which is composed of the door storage section 31, side plate section 32, and mounting fixtures 33 (34, 35, 36) constructed as described above, is attached to both side surfaces of the case body 1.

Next, we will explain the structure for attaching the side unit 3 to the case body 1.

Figure 19 is a partially enlarged perspective view of the case body 1, with Figure 19(a) being a partially enlarged perspective view of the upper side and Figure 19(b) being a partially enlarged perspective view of the lower side. Figure 20 is an enlarged view of part C shown in Figure 19 as seen from above. Figure 21 is a rear view of the case body 1. And Figure 22 is a conceptual diagram for explaining a method of attaching the side unit 3 to the case body 1. Figure 22(a) is a partial top view and Figure 22(b) is a partial rear view. Note that in Figures 21, 22 and Figure 23 described below, the back plate portion 13b of the outer panel 13 has been removed.

In this embodiment, the U-shaped opening between the left and right widthwise ends of the insulation member 11 shown in FIG. 2 and the left and right widthwise ends of the inner panel 12 is closed by an insulation panel 14 (see FIG. 19) that is U-shaped overall in a plan view. This insulation panel 14 consists of an upper insulation panel 14a on the upper end side of the case body 1, a lower insulation panel 14b on the lower end side, and a rear insulation panel 14c on the rear side.

In addition, rear brackets 15 are fixed to both widthwise ends of the rear surface of the rear surface portion 11a of the heat insulating member 11 of the case body 1 (see Figs. 19 to 21). The rear brackets 15 are members for attaching the back plate portion 13b of the outer panel 13 to the rear surface portion 11a of the heat insulating member 11 and for attaching the rear frame 311c of the side unit 3 to the case body 1, and extend in the vertical direction. The rear bracket 15 is made of a thin plate and is made up of a first vertical section 15a extending vertically along the rear section 11a, a second vertical section 15b facing the first vertical section 15a, a third vertical section 15c connecting one end of the first vertical section 15a in the width direction to one end of the second vertical section 15b in the width direction and having a surface flush with the outer surface of the insulation panel 14, a fourth vertical section 15d extending rearward from the other end of the second vertical section 15b in the width direction, and a fifth vertical section 15e extending from the tip of the fourth vertical section 15d toward the center of the case body 1 in the width direction.

For example, the upper frame 311a of the side unit 3 is screwed to the upper insulation panel 14a of the case body 1, the lower insulation box 311e fixed to the lower frame 311b of the side unit 3 is screwed to the lower insulation panel 14b of the case body 1, and the rear frame 311c of the side unit 3 is screwed to the third vertical part 15c of the rear bracket 15 of the case body 1, thereby attaching the side unit 3 to the case body 1 (see Figures 22(a) and 22(b)). Note that in this embodiment, as described above, the side unit 3 consisting of the door storage part 31, the side plate part 32, and the mounting fixture 33 (34, 35, 36), that is, the assembled unit assembled as the side unit 3, is attached to the case body 1, but this is not limited to this, and the side unit 3 may be divided into multiple units, and each unit may be assembled to the case body 1.

Here, the case body 1 is formed with a plurality of spare holes 10a at intervals that correspond to the intervals of the plurality of holes 31a for screwing to the mounting fixtures 33 formed in the door storage section 31. In this embodiment, the plurality of spare holes 10a in the case body 1 are formed to correspond to each mounting fixture 33 (34, 35, 36).

Specifically, the top plate portion 13a of the outer panel 13 of the case body 1 has a plurality of (five in the figure) first auxiliary holes 10a1 (see FIG. 19(a)) formed as the auxiliary holes 10a at intervals that match the intervals of the plurality of first holes 31a1 (see FIG. 14(b)) formed in the upper insulation box 311d of the door storage section 31. The second vertical portion 15b of the rear bracket 15 of the case body 1 has a plurality of (three in the figure) second auxiliary holes 10a2 (see FIGS. 20 and 21) formed as the auxiliary holes 10a at intervals that match the intervals of the plurality of second holes 31a2 (see FIG. 16(b)) formed in the rear frame 311c of the door storage section 31. In addition, the lower insulation panel 14b of the case body 1 has a plurality of (three in the figure) third auxiliary holes 10a3 (see FIG. 19(b)) formed as auxiliary holes 10a at intervals that match the intervals of the third holes 31a3 (see FIG. 18(b)) formed in the lower insulation box 311e of the door storage section 31. Each of the auxiliary holes 10a (10a1, 10a2, 10a3) is, for example, a screw hole (a female-threaded hole).

In this embodiment, although not particularly limited, in a showcase 100 having a door 4 and a door storage section 31, the screws inserted into the third upper through holes 34c formed in the upper mounting fixture 34 are screwed into the corresponding first auxiliary holes 10a1 in the top plate portion 13a of the outer panel 13, so that the upper edge of the side plate portion 32 is also screwed to the top plate portion 13a of the case body 1 via the upper mounting fixture 34 (see Figures 1, 3, and 4).

Next, an example of the procedure for converting (modifying) the showcase 100 into an open showcase 100' that does not have the door 4 and the door storage section 31 will be described. Figure 23 is a conceptual diagram for explaining conversion into an open showcase 100'. Figure 23(a) is a partial top view, and Figure 23(b) is a partial rear view.

First, the left and right lower side panels 22, 22 and each side unit 3 (3L, 3R) are removed from the showcase 100 shown in FIG. 1. Then, the side plate portion 32 and each mounting fixture 33 (34, 35, 36) are removed from each side unit 3. The door 4 and door storage portion 31 are stored, for example.

Next, the side panel 32 removed from the door storage section 31 is attached to the left and right sides of the case body 1 using the respective mounting fixtures 33 (34, 35, 36).

Specifically, the screws inserted into the first upper through holes 34a of the upper mounting fixture 34 screw into the corresponding first auxiliary holes 10a1 in the top plate 13a of the case body 1, and the screws inserted into the second upper through holes 34b screw into the upper edge portion of the protective cover 322 of the side plate 32, thereby fixing the upper edge of the side plate 32 to the top plate 13a of the case body 1 via the upper mounting fixture 34 (see FIG. 23(a)).

Then, the screws inserted into each rear through-hole 35a of the rear mounting fixture 35 screw into the corresponding second auxiliary holes 10a2 in the second vertical portion 15b of the rear bracket 15 of the case body 1, and the side plate clamping portion 351 of the rear mounting fixture 35 clamps the rear edge of the side plate 321, thereby fixing the rear edge of the side plate portion 32 to the rear bracket 15 of the case body 1 via the rear mounting fixture 35 (see FIG. 23(b)).

Furthermore, the screws inserted into each lower through hole 36a of the lower mounting fixture 36 screw into the corresponding third auxiliary hole 10a3 (see Figures 18 and 19) in the lower insulation panel 14b of the case body 1, and the first member 361 (see Figure 17) of the lower mounting fixture 36 supports the lower edge of the side plate 321, so that the lower edge of the side plate portion 32 is fixed to the lower insulation panel 14b of the case body 1 via the lower mounting fixture 36.

In this manner, the side panels 32 are attached to both sides of the case body 1. The showcase 100 has been modified to an open showcase 100' that does not have the door 4 and door storage section 31. The removed door 4 and door storage section 31 can then be stored. In place of the lower side panel 22, a separate lower side panel (not shown) that is narrower in width in the left-right direction by the width of the door storage section 31 can be prepared for the open showcase 100', and this lower side panel can be attached to the installation stand 2.

In the showcase 100 according to this embodiment, when the showcase 100 is used as an open showcase 100' without the door 4 and the door storage section 31, the door 4 and the door storage section 31 are removed from the case body 1, and the side plate section 32 is removed from the door storage section 31 together with the mounting fixture 33. The removed side plate section 32 is then simply screwed to the case body 1 via the mounting fixture 33 (34, 35, 36) using a plurality of spare holes 10a (10a1, 10a2, 10a3) formed in the case body 1. As a result, the side of the case body 1 is blocked by the side plate section 32, which is a showcase component (a component of the showcase 100). As a result, the showcase 100 having the door 4 and the door storage section 31 can be easily reassembled into an open showcase 100' without the door 4 and the door storage section 31. In this way, it is possible to provide a showcase 100 that can be easily reassembled into an open showcase 100' that does not have a door 4 or a door storage section 31 while closing the side of the case body 1 by reusing the showcase components.

In addition, the open showcase 100' can be easily converted to the showcase 100. For example, the open showcase 100' may be installed first, and then it may be requested to convert it to the showcase 100. In this case, by adding the door 4 and the door storage section 31, it can be easily converted to the showcase 100.

Here, when assembled into the open showcase 100', the multiple spare holes 10a (10a1, 10a2, 10a3) provided in the case body 1 are actually used as holes for screwing the side panel portion 32 to the case body 1 via the mounting fixtures 33 (34, 35, 36). Considering that they are actually used, in the open showcase 100' state, the multiple spare holes 10a are not "spare" holes in the literal sense.

In this embodiment, in the state of the showcase 100, the first spare hole 10a1 among the spare holes 10a is screwed with a screw inserted through each of the third upper through holes 34c formed in the upper mounting fixture 34, and the first spare hole 10a1 is actually used as a hole for screwing. However, the first spare hole 10a1 may be unused and exist as a "spare" hole in the state of the showcase 100, similar to the second spare hole 10a2 and the third spare hole 10a3. In other words, in the state of the showcase 100, the multiple spare holes 10a (10a1, 10a2, 10a3) are literally "spare" holes that are not used as holes for screwing the side plate portion 32 to the case body 1, and are used as holes for screwing the side plate portion 32 to the case body 1 in the state of the open showcase 100'. In this way, the spare hole 10a is defined as a "spare" hole starting from the state of the showcase 100. Starting from the state of the open showcase 100', the spare hole 10a is a hole that is actually used as a screw fastening hole in the state of the open showcase 100', and when the door 4 and the door storage section 31 are added to this open showcase 100' and reassembled into the showcase 100 (i.e., in a retrofitted state), it functions as a "spare" hole.

In addition, in this embodiment, the showcase 100 is assembled by attaching the side unit 3 (i.e., an assembly unit assembled together as the side unit 3) consisting of the door storage section 31, the side panel section 32, and the mounting fixtures 33 (34, 35, 36) to the case body 1 as described above. However, this is not limited to this, and the showcase 100 may be assembled by dividing the side unit 3 into multiple small units and attaching each small unit individually to the case body 1.

In addition, in this embodiment, the mounting fixtures 33 are provided for screwing to the upper end portion of the door storage section 31, screwing to the rear end portion of the door storage section 31, and screwing to the lower end portion of the door storage section 31. In other words, the showcase 100 has an upper mounting fixture 34, a rear mounting fixture 35, and a lower mounting fixture 36 as the mounting fixtures 33, but is not limited to this and does not necessarily have to have an upper mounting fixture 34.

In this embodiment, the door storage section 31 is arranged on both the left and right sides of the case body 1, but this is not limiting, and the door storage section 31 may be arranged on only one side (not shown). In this case, the side plate section 32 is directly attached via the mounting fixture 33 to the side of the case body 1 on which the door storage section 31 is not arranged. The opening on the front opening of the case body 1 on the side on which the door storage section 31 is not arranged may be left open as it is, or may be covered with a fixed plate such as a glass plate, or the shaft section 313b of the door 4 may be fixed to the edge of the case body 1 on the side on which the door storage section 31 is not arranged, and the door 4 may simply be opened and closed by rotating around this shaft section 313b.

In addition, the front opening of the case body 1 is opened and closed by a double door consisting of the left and right doors 4, but this is not limited to this. For example, the entire front opening of the case body 1 may be opened and closed by a single door 4 as a single door. In this case, the door storage section 31 is provided on only one side of the case body 1, and a side panel section 32 is attached to the side of the case body 1 on which the door storage section 31 is not located.

The left and right doors 4 are used to open and close the entire front opening of the case body 1, but this is not limiting, and one or more additional doors 4 may be provided between the left door 4 stored in the left door storage section 31 and the right door 4 stored in the right door storage section 31. In this case, the one or more additional doors 4 simply open and close. In addition, the product display room 5 is formed as one room, but this is not limiting, and for example, partitions may be provided within the product display room 5 to partition the room into areas corresponding to each door 4 or areas corresponding to multiple doors 4.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and further modifications and variations are possible based on the technical concept of the present invention.
