[0061] (Insights, etc. that form the basis of this disclosure)

[0062] When the inventors came up with the present disclosure, in a showcase, the holder of the lighting device was fixed to a shelf of the showcase by screw fastening or inserting an arrow-shaped fastener.

[0063] However, in the prior art, screws and the like are used when mounting the retainer on the shelf. Therefore, in order to eliminate the interference between the screws and the shelf lighting, it is necessary to ensure a gap between the shelf lighting and the shelf. Therefore, there is a problem that the height dimension of the shelf equipped with the shelf lighting becomes larger and the effective storage volume of the display case becomes smaller. In addition, the inventors found that since the retainer is fixed by screws or fasteners, there is a problem that the retainer is easily detached due to its vibration when the display case is transported. In order to solve this problem, the subject of the present disclosure is formed.

[0064] Therefore, the present disclosure provides a lighting fixture and a storage room that can fix shelf lighting without increasing the height dimension of the shelf.

[0065] Hereinafter, the embodiments are described in detail with reference to the accompanying drawings. However, sometimes, a detailed description beyond what is necessary is omitted. For example, sometimes, a detailed description of a known matter or a repeated description of a substantially identical structure is omitted. This is to avoid the following description being too lengthy and to make it easy for those skilled in the art to understand.

[0066] In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0067] (Implementation Method 1)

[0068] Hereinafter, Embodiment 1 will be described using the drawings.

[0069] [1-1. Structure]

[0070] [1-1-1. Overall structure of the display cabinet]

[0071] Figure 1 It is a cross-sectional view of the showcase 1, and shows a cross section perpendicular to the width direction of the showcase 1. In addition, in this embodiment, the case where an open showcase is applied as the storage of the present disclosure is described as an example.

[0072] The showcase 1 is placed on the floor of a supermarket, convenience store, or the like, and displays beverages, foods, and other commodities in a refrigerated state. The showcase 1 is a so-called open showcase.

[0073] The showcase 1 has a substantially box-shaped housing 11 with an open front surface for taking out and putting in commodities.

[0076] A base portion 18 is provided on the lower surface of the bottom wall 13 to be placed on the floor, which is the placement surface of the showcase 1. The base portion 18 supports the housing 11 via the upper surface.

[0077] An inner wall 20 is provided inside the housing 11, which is separated from the inner surface of the housing 11 and covers the housing 11 from the inside. The inner wall 20 has a partition wall 22 extending in the up-down direction in front of the rear wall 15. The inner wall 20 has an inner upper wall 24 extending forward from the upper end of the partition wall 22 along the upper wall 16. The inner wall 20 has a bottom plate 26 extending forward substantially horizontally from the lower end of the partition wall 22 and connected to the upper part of the lower front wall 17.

[0078] The display room 12 is formed by being partitioned by the inner wall 20 and the side walls 14. For example, the partition wall 22 functions as a back panel constituting the back side of the display room 12.

[0079] A plurality of shelves 28 on which commodities are placed and displayed are provided inside the display room 12. The shelves 28 are arranged in the vertical direction, attached to the partition wall 22 at intervals, and extend substantially horizontally toward the front.

[0080] In the present embodiment, the bottom plate 26 is configured to display goods, and the bottom plate 26 functions as a shelf at the bottom. The front end of the bottom plate 26 is located in front of the front ends of the shelves 28. In the present embodiment, four shelves 28 are arranged in a vertical arrangement, but the number of shelves 28 may be any number of one or more. In addition, a structure in which no shelf 28 is provided is also possible.

[0081] A duct 30 is formed between the inner wall 20 and the housing 11. The duct 30 is a space surrounded by the inner wall 20, the bottom wall 13, the side walls 14, the lower front wall 17, the rear wall 15, and the upper wall 16.

[0082] The duct 30 includes a lower duct 32 formed between the bottom plate 26 and the bottom wall 13 and extending in the front-rear direction. The duct 30 includes a back duct 34 formed between the partition wall 22 and the rear wall 15 and extending in the up-down direction. The duct 30 includes an upper duct 36 formed between the inner upper wall 24 and the upper wall 16 and extending in the front-rear direction. The display room 12 is surrounded by the lower duct 32, the back duct 34, and the upper duct 36.

[0083] The top duct 36 has a blowout port 37 at its front end. The blowout port 37 is opened downward and communicates with the display room 12. The blowout port 37 is provided below the front end of the top wall 16 and above the front side of the display room 12.

[0084] A suction port 38 is provided at the upper portion of the front end of the lower duct 32. The suction port 38 is an opening that opens upward and communicates with the display chamber 12. The suction port 38 is provided at the lower front portion of the display chamber 12 continuously with the rear portion of the lower front wall 17. The suction port 38 is located at a position forward of the blowout port 37. The blowout port 37 and the suction port 38 extend elongatedly between the side walls 14 over the substantially entire width direction of the housing 11.

[0085] The showcase 1 has a cooling system 31 for cooling the display room 12. The cooling system is a refrigeration cycle composed of a compressor for compressing a refrigerant, an evaporator 31a, a condenser, and an expansion mechanism connected in a loop by pipes, and the refrigerant is sealed in the cooling system.

[0086] In the present embodiment, the evaporator 31a is disposed inside the duct 30 provided in the housing 11, and the compressor, condenser, and expansion mechanism are housed in an outdoor unit separate from the showcase 1. In addition, the compressor, condenser, and expansion mechanism may be housed inside the base 18, for example, and may be integrally provided in the showcase 1.

[0087] The blower 33 is provided inside the duct 30. The blower 33 includes a motor 33a and an impeller 33b attached to the output shaft of the motor 33a. The blower 33 rotates the impeller 33b by the motor 33a, thereby circulating the air (cool air) cooled by the evaporator 31a by blowing air.

[0088] A top cover 39 is attached to the front end portion 16a of the upper wall 16 of the housing 11. The top cover 39 is provided over substantially the entire front end portion 16a in the width direction.

[0089] An exterior lighting 51 is provided on the inner side of the top cover 39 .

[0090] The exterior lighting 51 is located outside the display room 12 . In the present embodiment, the exterior lighting 51 is composed of LEDs (Light Emitting Diodes). The exterior lighting 51 emits light toward the rear and downward. The exterior lighting 51 illuminates the interior of the display room 12 .

[0091] The upper interior lighting 53 is a lighting device located inside the display room 12. The upper interior lighting 53 is installed on the inner upper wall 24 of the inner wall 20. In this embodiment, the upper interior lighting 53 is composed of LEDs. The upper interior lighting 53 emits light downward. The upper interior lighting 53 illuminates the inside of the display room 12.

[0092] The showcase 1 is divided into an interior for storing commodities and an exterior as the outside thereof. The interior includes a display room 12, for example, an area where airflow supplied by a blower 33 circulates. The exterior is a portion of the showcase 1 that is not included in the interior.

[0093] The air flow of the blower 33 forms an air curtain, by which, for example, Figure 1 As shown by the dotted line 11 a , the inside and outside of the storage compartment are divided by a surface connecting the lower end of the top cover 39 and the upper end of the lower front wall 17 .

[0094] [1-1-2. Structure of shelf lighting and lighting fixtures]

[0095] A shelf lighting 55 is provided on the lower surface side of the distal end portion of the shelf.

[0096] The shelf lighting 55 is a lighting device located inside the display room 12. The shelf lighting 55 is installed on the front of each shelf 28. The shelf lighting 55 is installed on the lower surface of each shelf 28. The shelf lighting 55 is a lighting device such as an LED, a fluorescent lamp, or an incandescent lamp. The shelf lighting 55 emits light downward and backward. The shelf lighting 55 illuminates the inside of the display room 12.

[0097] Figure 2 It is a perspective view showing the lower surface side of the shelf plate. Figure 3 It is a cross-sectional view of the front end portion of the shelf. Figure 4 is a three-dimensional diagram of a lighting fixture. Figure 5 is a cross-sectional view of a lighting fixture. Figure 6 It is a cross-sectional view showing a state where the shelf lighting 55 is mounted on the lighting fixture.

[0098] like Figure 2 As shown, the shelf plate 28 is formed of a plate-like member such as a metal plate. A flange portion 40 extending downward is formed around the shelf plate 28. Two reinforcing ribs 41, 41 extending in the width direction are installed on the lower surface of the shelf plate 28 at a predetermined interval in the front-rear direction.

[0099] A lighting mounting member 42 is provided on the lower surface side of the front end portion of the shelf plate 28 .

[0100] The lighting mounting member 42 includes a fixing plate 43 fixed to the lower surface of the shelf 28. A lighting mounting plate 44 protruding downward is provided at the substantially front-rear center of the fixing plate 43. The lighting mounting plate 44 is disposed at a predetermined gap from the lower surface of the shelf.

[0101] A plurality of lightening holes 45 arranged in the width direction are formed in the lighting mounting plate 44. The lightening holes 45 include two lightening holes 45 that are paired in the front-rear direction, and the paired lightening holes 45 are arranged in the width direction of the lighting mounting plate 44.

[0102] Fixture mounting holes 46 are formed at both ends and a substantially central portion of the lighting mounting plate 44. The fixture mounting holes 46 are openings having substantially the same width in the front-rear direction as the paired lightening holes 45.

[0103] A plate mounting member 47 is provided continuously at the front end of the lighting mounting member 42. The plate mounting member 47 is formed into a shape extending obliquely downward from the front end of the lighting mounting member 42, extending forward from below the flange portion 40, and extending upward.

[0104] A portion of the panel mounting member 47 that faces the front surface of the flange portion 40 serves as a panel support surface 48 .

[0105] like Figure 2 As shown, a lighting fixture 60 is mounted in the fixture mounting hole 46 .

[0106] The lighting fixture 60 is formed of a flexible resin such as plastic.

[0107] like Figure 4 and Figure 5 As shown, the lighting fixture 60 includes a plate-shaped main body 61. On one end of the main body 61 closer to the center, an elastic portion 62 is formed to protrude from the surface of the main body 61 and is formed in a substantially U-shape. Figure 5 In the embodiment, the main body 61 is configured such that both end portions can approach each other in the longitudinal direction via the elastic portion 62 .

[0108] The elastic portion 62 of the main body 61 is provided with a first locking portion 63 protruding toward the end of the main body 61. The first locking portion 63 includes a first claw 63a provided with a predetermined gap from the upper surface of the main body 61.

[0109] Here, the predetermined gap is formed to be slightly larger than the thickness dimension of the lighting mounting plate 44 .

[0110] The second locking portion 64 protruding toward the end of the main body 61 is provided at the end of the main body 61 opposite to the end where the first locking portion 63 is formed. The second locking portion 64 includes a second claw 64a provided with a predetermined gap from the upper surface of the main body 61.

[0111] Here, the predetermined gap is formed to be slightly larger than the thickness dimension of the lighting mounting plate 44 .

[0112] A pair of lighting holding portions 65 are formed at both ends of the main body 61 and extend toward the side opposite to the side where the first locking portion 63 and the second locking portion 64 are formed. The lighting holding portion 65 extends from the side opposite to the side where the two locking portions 63 and 64 are formed, that is, Figure 5 The lighting holding portion 65 extends obliquely downward from both ends of the main body portion 61 and is formed into a substantially L-shape via a bent portion 65 a . An expanded portion 66 that expands outward is formed at a distal end portion of the lighting holding portion 65 .

[0113] A wiring holding portion 67 extending toward one side of the first locking portion 63 and the second locking portion 64 forming the main body 61 is formed in the middle of the lighting holding portion 65 .

[0114] like Figure 6 As shown, the lighting fixture 60 is mounted in the fixture mounting hole 46 formed in the lighting mounting plate 44 of the frame plate 28 .

[0115] The lighting fixture 60 is fixed to the lighting mounting plate 44 by engaging the first locking portion 63 and the second locking portion 64 with the fixture mounting hole 46. The shelf lighting 55 is fixed to the lighting fixture 60 by being pressed between the lighting holding portions 65.

[0116] In addition, if Figure 6 As shown, the shelf lighting 55 has a protruding portion 55 a formed at a position corresponding to the substantially L-shaped bent portion 65 a of the lighting holding portion 65 so as to protrude outward and follow the shape of the lighting holding portion 65 .

[0117] Therefore, by making the protruding portion 55a of the shelf lighting 55 correspond to the bent portion 65a of the lighting holding portion 65, the protruding portion 55a of the shelf lighting 55 is located outside the distal end of the lighting holding portion 65, thereby preventing the shelf lighting 55 from falling off.

[0118] Here, the interval between the two lighting holders 65 is formed to be slightly smaller than the distance between the distal ends of the protruding portions 55a of the shelf lighting 55. Therefore, when the shelf lighting 55 is mounted between the lighting holders 65, a force toward the outside acts on each lighting holder 65, so that the shelf lighting 55 can be firmly held by the lighting holders 65.

[0119] Furthermore, since an outward force acts on the lighting holding portion 65 , the main body 61 is pressed against the lighting mounting plate 44 , and the locking by the first locking portion 63 and the second locking portion 64 can be made difficult to be released.

[0120] [1-2. Function]

[0121] Next, the effects of the present disclosure will be described.

[0122] The procedure for installing the shelf lighting 55 will be described.

[0123] Figure 7 It is a perspective view showing a state in the middle of attaching the lighting fixture 60 . Figure 8 It is a perspective view showing a state where the lighting fixture 60 is mounted.

[0124] First, if Figure 7 As shown, the first locking portion 63 of the lighting fixture 60 is inserted into the fixture mounting hole 46. Thus, the edge of the fixture mounting hole 46 is clamped between the first claw portion 63a of the first locking portion 63 and the main body 61.

[0125] Next, a pressing force is applied in the direction in which the expanded portions 66 of the lighting fixture 60 approach each other. As a result, the elastic portion 62 is bent and deformed, and the distance between the first locking portion 63 and the second locking portion 64 is shortened.

[0126] In this state, the second locking portion 64 is inserted into the fixing hole 46, and then the pressing force at the expanded portion 66 is released, thereby returning the elastic portion 62 to its original state. As a result, the distance between the first locking portion 63 and the second locking portion 64 is returned to its original state, so that the second claw portion 64a of the second locking portion 64 and the main body 61 clamp the edge of the fixing hole 46.

[0127] Therefore, if Figure 8 As shown, the first locking portion 63 and the second locking portion 64 are engaged with the fixing member mounting hole 46 .

[0128] Next, the shelf lighting 55 is pressed between the lighting holding portions 65 , so that the shelf lighting 55 is fixed to the lighting mounting plate 44 of the lighting mounting member 42 .

[0129] In this case, since the expansion portion 66 protruding outward is formed at the distal end of the lighting holding portion 65, when the shelf lighting 55 is pressed between the lighting holding portions 65, the shelf lighting 55 first abuts against the expansion portion 66, and a force that opens the lighting holding portion 65 outward can be applied by the pressing of the shelf lighting 55. Thus, the shelf lighting 55 can be easily assembled to the lighting holding portion 65 simply by pressing the expansion portion 66.

[0130] Furthermore, since the interval between the two lighting holding portions 65 is formed to be slightly smaller than the distance between the terminal ends of each protrusion 55a of the shelf lighting 55, when the shelf lighting 55 is mounted between the lighting holding portions 65, a force toward the outside acts on each lighting holding portion 65, so that the shelf lighting 55 can be firmly held with the aid of the lighting holding portions 65.

[0131] In addition, since the outward force acts on the lighting holding portion 65, the main body 61 is pressed against the lighting mounting plate 44. Thus, the lighting mounting plate 44 is clamped by the first and second locking portions 63 and 64 and the main body 61, and the locking by the first and second locking portions 63 and 64 is not easily disengaged.

[0132] After the shelf lighting 55 is installed, Figure 6 As shown, the lighting wiring 68 of the shelf lighting 55 is accommodated between the wiring holding portion 67 and the fixing plate 43 of the lighting mounting member 42 .

[0133] Thereby, the lighting wiring 68 of the shelf lighting 55 can be centralized without using other components.

[0134] At this time, since the force toward the outside acts on the lighting holding portion 65, the wiring holding portion 67 also moves toward the lighting mounting plate 44. Therefore, after the lighting wiring 68 is accommodated between the wiring holding portion 67 and the fixing plate 43 of the lighting mounting member 42, the shelf lighting 55 is assembled to the lighting holding portion 65, so that the gap between the terminal end of the wiring holding portion 67 and the fixing plate 43 can be reduced. As a result, it is possible to suppress the lighting wiring 68 from falling off.

[0135] [1-3. Effects, etc.]

[0136] As described above, the lighting fixture 60 of the present embodiment comprises: a main body 61; an elastic portion 62, which is formed in the middle of the main body 61; a first locking portion 63 and a second locking portion 64 (a pair of locking portions), which are arranged on the main body 61 via the elastic portion 62 and engage with the fixing mounting hole 46 (hole) of the lighting mounting plate 44 provided on the shelf 28 of the display cabinet; and a lighting holding portion 65, which extends to the side of the main body 61 opposite to the side where the first locking portion 63 and the second locking portion 64 are formed, and holds the side of the shelf lighting 55.

[0137] Thus, the lighting fixture 60 is fixed by engaging the first locking portion 63 and the second locking portion 64 with the fixture mounting hole 46, and the shelf lighting 55 is fixed by holding the shelf lighting 55 on the lighting holding portion 65. In addition, since the lighting fixture 60 is not fixed by screws or the like as in the past, it is not necessary to ensure a gap between the shelf lighting 55 and the shelf 28, and the height dimension of the shelf 28 equipped with the shelf lighting 55 can be reduced. As a result, the thickness of the shelf 28 can be suppressed, and the effective storage volume of the showcase can be ensured to be large.

[0138] Furthermore, since the lighting fixture 60 is fixed to the frame plate 28 by locking the first locking portion 63 and the second locking portion 64 in the fixture mounting hole 46 , it is possible to suppress the lighting fixture 60 from coming off due to vibration or the like.

[0139] In the lighting fixture 60 of the present embodiment, the first locking portion 63 and the second locking portion 64 (locking portion) include a first claw portion 63a and a second claw portion 64a (claw portion) at their distal ends that engage with the fixture mounting hole 46 (hole).

[0140] Thus, the lighting fixture 60 can be reliably fixed to the frame plate 28 by engaging the first claw portion 63 a and the second claw portion 64 a with the fixture mounting hole 46 .

[0141] In addition, in the lighting fixture 60 of the present embodiment, the interval between the lighting holding portions 65 is formed to be smaller than the width dimension of the shelf lighting 55 .

[0142] Thus, when the shelf lighting 55 is mounted on the lighting fixture 60, an outward force acts on the lighting holding portion 65, thereby pressing the main body 61 against the lighting mounting plate 44. Therefore, the lighting mounting plate 44 is clamped by the first locking portion 63 and the second locking portion 64 and the main body 61, and the locking by the first locking portion 63 and the second locking portion 64 is not easily disengaged.

[0143] In addition, in the lighting fixture 60 of the present embodiment, the expanded portion 66 that protrudes outward is formed at the distal end portion of the lighting holding portion 65 .

[0144] Thus, by applying a pressing force in the direction of approaching the lighting holding parts 65 by the expanded part 66, the lighting fixture 60 can be deformed by the elastic part 62. Therefore, the first locking part 63 and the second locking part 64 can be easily engaged with the fixture mounting hole 46.

[0145] Furthermore, since the expanded portion 66 protrudes outward, when the shelf lighting 55 is mounted on the lighting fixture 60 , the lighting holding portion 65 can be deformed outward simply by pressing the shelf lighting 55 against the expanded portion 66 . Therefore, the shelf lighting 55 can be easily mounted on the lighting fixture 60 .

[0146] In the lighting fixture 60 of the present embodiment, the lighting holding portion 65 is provided with a wiring holding portion 67 extending toward the side of the main body 61 where the first locking portion 63 and the second locking portion 64 (locking portion) are formed.

[0147] Thus, the lighting wiring 68 of the shelf lighting 55 can be concentrated without using other parts. In addition, since the force toward the outside acts on the lighting holding portion 65, the wiring holding portion 67 moves toward the lighting mounting plate 44, which can reduce the gap between the terminal end of the wiring holding portion 67 and the fixing plate 43, and can prevent the lighting wiring 68 from falling off.

[0152] [Structure supported by the above-mentioned embodiment]

[0153] The above-mentioned embodiment supports the following structure.

[0154] (Note)

[0155] (Technology 1) A lighting fixture, which is used to fix a shelf lighting to a shelf, wherein the lighting fixture comprises: a main body; an elastic portion formed in the middle of the main body; a pair of locking portions, which are arranged on the main body across the elastic portion and engage with holes provided on the shelf; and a lighting holding portion, which extends to the side of the main body opposite to the side where the locking portion is formed, to hold the side of the shelf lighting.

[0156] According to this structure, the lighting fixture can be fixed by engaging the locking portion with the hole, and the shelf lighting can be fixed by holding the shelf lighting with the lighting holding portion. In addition, since the lighting fixture is not fixed using screws or the like as in the past, it is not necessary to ensure a gap between the shelf lighting and the shelf, and the height dimension of the shelf equipped with the shelf lighting can be reduced. As a result, the thickness of the shelf can be suppressed, and the effective storage volume of the storage warehouse can be ensured to be large.

[0157] Furthermore, since the lighting fixture is fixed to the shelf by locking the locking portion in the hole, it is possible to suppress the lighting fixture from coming off due to vibration or the like.

[0158] (Technique 2) The lighting fixture according to Technique 1, wherein the locking portion includes a claw portion that engages with the hole at a distal end thereof.

[0159] According to this configuration, the lighting fixture can be reliably fixed to the shelf plate by engaging the claw portion with the hole.

[0160] (Technique 3) The lighting fixture according to Technique 1 or Technique 2, wherein the interval between the lighting holding portions is formed to be smaller than a width dimension of the shelf lighting.

[0161] According to this structure, when the shelf lighting is mounted on the lighting fixture, the lighting holding portion is subjected to an outward force, thereby pressing the main body against the lighting mounting plate. Therefore, the lighting mounting plate is clamped by the locking portion and the main body, and the locking by the locking portion is not easily disengaged.

[0162] (Technique 4) The lighting fixture according to any one of Techniques 1 to 3, wherein a widened portion protruding outward is formed at a distal end portion of the lighting holding portion.

[0163] According to this configuration, the lighting fixture can be deformed by the elastic portion by applying a pressing force in a direction to bring the lighting holding portions closer to each other via the expanded portion. Therefore, the locking portion can be easily engaged with the fixture mounting hole.

[0164] Furthermore, since the expanded portion protrudes outward, when the shelf lighting is mounted on the lighting fixture, the lighting holding portion can be deformed outward simply by pressing the shelf lighting against the expanded portion. Therefore, the shelf lighting can be easily mounted on the lighting fixture.

[0165] (Technique 5) The lighting fixture according to any one of Techniques 1 to 4, wherein the lighting holding portion includes a wiring holding portion extending toward a side of the main body portion where the locking portion is formed.

[0166] According to this structure, the lighting wiring of the shelf lighting can be concentrated without using other components. In addition, since the force toward the outside acts on the lighting holding part, the wiring holding part moves toward the lighting mounting plate side, which can reduce the gap between the terminal end of the wiring holding part and the fixing surface, and can prevent the lighting wiring from falling off.

[0167] (Technique 6) A storage room comprising a shelf equipped with the lighting fixture according to any one of Techniques 1 to 5, wherein a shelf lighting is mounted on the lighting fixture.

[0168] According to this structure, the lighting fixture is fixed by engaging the locking portion with the fixture mounting hole, and the shelf lighting is fixed by the lighting holding portion. In addition, since the lighting fixture is not fixed using screws or the like as in the past, it is not necessary to ensure a gap between the shelf lighting and the shelf, and the height dimension of the shelf equipped with the shelf lighting can be reduced. As a result, the thickness of the shelf can be suppressed, and the effective storage volume of the storage warehouse can be ensured to be large.

[0169] Furthermore, since the lighting fixture is fixed to the frame plate by locking the locking portion in the fixture mounting hole, it is possible to suppress the lighting fixture from coming off due to vibration or the like.

[0170] In addition, since the force toward the outside acts on the lighting holding part, the main body is pressed against the lighting mounting plate. Thus, the lighting mounting plate is clamped by the locking part and the main body, and the locking by the locking part can be made difficult to be disengaged.

[0171] Industrial Applicability

[0172] The present invention discloses a lighting fixture that can fix shelf lighting without increasing the height of the shelf, and can be appropriately used in storages such as showcases that require shelf lighting.
