[0008] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the idea of ​​the present disclosure, in a showcase, a holder for a lighting device was fixed to a shelf board of the showcase by fastening with a screw or by inserting an arrowhead-shaped fastener. However, in the conventional technology, screws or the like are used to attach the holder to the shelf, and a gap must be secured between the shelf light and the shelf to prevent interference between the screws and the shelf light. This increases the height of the shelf on which the shelf light is attached, which reduces the effective internal volume of the showcase. The inventors also discovered that, since the holder is fixed with screws or fasteners, there is a problem that the holder is easily dislodged due to vibrations during transportation of the showcase, and the subject of the present disclosure was created to solve this problem. Therefore, the present disclosure provides a lighting fixture and a storage unit that can fix shelf lighting without increasing the height dimension of the shelf.

[0026] Fig. 2 is a perspective view showing the underside of the shelf. Fig. 3 is a cross-sectional view of the front end portion of the shelf. Fig. 4 is a perspective view of the lighting fixture. Fig. 5 is a cross-sectional view of the lighting fixture. Fig. 6 is a cross-sectional view showing the shelf lighting 55 attached to the lighting fixture.

[0027] 2, the shelf board 28 is made of a plate-like member such as sheet metal. A downwardly extending flange portion 40 is formed around the periphery of the shelf board 28. Two reinforcing ribs 41, 41 extending in the width direction are attached to the underside of the shelf board 28 at a predetermined interval in the front-rear direction. An illumination mounting member 42 is provided on the underside of the front end of the shelf board 28.

[0028] The lighting mounting member 42 includes a fixed plate 43 that is fixed to the underside of the shelf board 28. A lighting mounting plate 44 that protrudes downward is provided at approximately the center in the front-to-rear direction of the fixed plate 43. The lighting mounting plate 44 is disposed with a predetermined gap from the underside of the shelf board. A plurality of lightening holes 45 arranged along the width direction are formed in the lighting mounting plate 44. The lightening holes 45 include two pairs of lightening holes 45 in the front-rear direction, and these pairs of lightening holes 45 are arranged in the width direction of the lighting mounting plate 44. Fixture attachment holes 46 are formed at both ends and approximately at the center of the lighting attachment plate 44. The fixture attachment holes 46 are openings having approximately the same width in the front-rear direction as the pair of lightening holes 45.

[0029] A plate mounting member 47 is provided continuously to the front end of the lighting mounting member 42. The plate mounting member 47 extends obliquely downward from the front end of the lighting mounting member 42, then extends forward from below the flange portion 40, and is formed in a shape that extends upward. The portion of the plate mounting member 47 facing the front surface of the flange portion 40 serves as a plate support surface 48 .

[0030] As shown in FIG. 2, a lighting fixture 60 is attached to the fixture attachment hole 46 . The lighting fixture 60 is formed from, for example, a flexible resin such as plastic. 4 and 5, the lighting fixture 60 includes a plate-shaped main body 61. From the middle of the main body 61 toward one end of the main body, a substantially U-shaped elastic portion 62 is formed so as to protrude from the surface of the main body 61. The main body 61 is configured such that both end portions can approach each other in the length direction in FIG. 5 due to the elastic portion 62. A first locking portion 63 is formed on the elastic portion 62 of the main body portion 61, protruding toward the end side of the main body portion 61. The first locking portion 63 includes a first claw portion 63a provided with a predetermined gap from the upper surface of the main body portion 61. Here, the predetermined gap is formed to be slightly larger than the thickness dimension of the lighting mounting plate 44 .

[0031] The end of the main body 61 opposite to the end where the first locking portion 63 is formed is provided with a second locking portion 64 that protrudes toward the end of the main body 61. The second locking portion 64 is provided with a second claw portion 64a provided with a predetermined gap from the upper surface of the main body 61. Here, the predetermined gap is formed to be slightly larger than the thickness dimension of the lighting mounting plate 44 .

[0032] A pair of lighting holders 65 are formed on both ends of the main body 61, extending in a direction opposite to the side where the first and second locking portions 63 and 64 are formed. The lighting holders 65 extend diagonally downward from both ends of the main body 61 in the direction opposite to the side where the first and second locking portions 63 and 64 are formed, i.e., in FIG. 5, are formed in a substantially L-shape via bent portions 65a, and an expansion portion 66 that expands outward is formed at the tip of the lighting holder 65. A wiring holding portion 67 is formed in the middle of the lighting holding portion 65, and extends to the side of the main body 61 where the first locking portion 63 and the second locking portion 64 are formed.

[0033] As shown in FIG. 6, the lighting fixture 60 is attached to the fixture attachment hole 46 formed in the lighting mounting plate 44 of the shelf board 28. 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 press-fitted between the lighting holding portions 65. As shown in FIG. 6, the shelf lighting 55 has a protrusion 55a formed at a position corresponding to the approximately L-shaped bent portion 65a of the lighting holding portion 65 so as to protrude outward and conform to the shape of the lighting holding portion 65. Therefore, since the protrusion 55a of the shelf lighting 55 corresponds to the bent portion 65a of the lighting holding portion 65, the protrusion 55a of the shelf lighting 55 is positioned outward relative to the tip of the lighting holding portion 65, thereby preventing the shelf lighting 55 from falling off.

[0034] Here, the distance between the two lighting holders 65 is formed slightly smaller than the distance between the tips of the protrusions 55a of the shelf lighting 55. Therefore, when the shelf lighting 55 is attached between the lighting holders 65, an outward force acts on each lighting holder 65, so that the lighting holders 65 can firmly hold the shelf lighting 55. In addition, an outward force acts on the lighting holding portion 65, pressing the main body 61 against the lighting mounting plate 44, making it difficult for the first and second locking portions 63 and 64 to come loose.

[0035] [1-2. Effect] Next, the operation of the present disclosure will be described. The procedure for installing the shelf lighting 55 will be described. Fig. 7 is a perspective view showing a state in the middle of attaching the lighting fixture 60. Fig. 8 is a perspective view showing a state after the lighting fixture 60 has been attached. 7, the first locking portion 63 of the lighting fixture 60 is inserted into the fixture attachment hole 46. As a result, the edge of the fixture attachment hole 46 is sandwiched between the first claw portion 63a of the first locking portion 63 and the main body portion 61.

[0036] Next, a pressing force is applied in a direction in which the widening portions 66 of the lighting fixture 60 approach each other. As a result, the elastic portion 62 is flexed and deformed, and the distance between the first locking portion 63 and the second locking portion 64 becomes shorter. In this state, after inserting the second locking portion 64 into the fastener attachment hole 46, the pressing force of the expanding portion 66 is released, and the deformation of the elastic portion 62 returns to its original state. As a result, the distance between the first locking portion 63 and the second locking portion 64 returns to its original state, and the edge of the fastener attachment hole 46 is sandwiched between the second claw portion 64a of the second locking portion 64 and the main body portion 61. As a result, the first locking portion 63 and the second locking portion 64 are engaged with the fastener attachment hole 46 as shown in FIG.

[0037] Next, the shelf board lighting 55 is press-fitted between the lighting holding parts 65, whereby the shelf board lighting 55 is fixed to the lighting mounting plate 44 of the lighting mounting member 42. In this case, since an expansion portion 66 that protrudes outward is formed at the tip of the lighting holding portion 65, when the shelf lighting 55 is press-fitted between the lighting holding portions 65, the shelf lighting 55 first comes into contact with the expansion portion 66, and a force that opens the lighting holding portions 65 outward can be applied by pressing the shelf lighting 55. This allows the shelf lighting 55 to be easily attached to the lighting holding portions 65 by simply pressing it into the expansion portion 66.

[0038] Furthermore, the spacing between the two lighting holding parts 65 is formed slightly smaller than the distance between the tips of each protrusion 55a of the shelf lighting 55. Therefore, when the shelf lighting 55 is attached between the lighting holding parts 65, an outward force acts on each lighting holding part 65, so that the lighting holding parts 65 can firmly hold the shelf lighting 55. Furthermore, an outward force acts on the lighting holding portion 65, so that the main body portion 61 is pressed against the lighting mounting plate 44. As a result, the lighting mounting plate 44 is sandwiched between the first locking portion 63, the second locking portion 64, and the main body portion 61, making it difficult for the first locking portion 63 and the second locking portion 64 to come loose.

[0039] After the shelf board light 55 is attached, the lighting wiring 68 of the shelf board light 55 is housed between the wiring holder 67 and the fixing plate 43 of the lighting attachment member 42, as shown in FIG. This makes it possible to bundle the lighting wiring 68 of the shelf board lighting 55 without using a separate component. At this time, an outward force acts on the lighting holding part 65, so that the wiring holding part 67 is also moved toward the lighting mounting plate 44. Therefore, by storing the lighting wiring 68 between the wiring holding part 67 and the fixing plate 43 of the lighting mounting member 42 and then attaching the shelf board lighting 55 to the lighting holding part 65, the gap between the tip of the wiring holding part 67 and the fixing plate 43 can be reduced. As a result, it is possible to prevent the lighting wiring 68 from falling off.

[0040] [1-3. Effects, etc.] As described above, the lighting fixture 60 in this embodiment comprises a main body portion 61, an elastic portion 62 formed in the middle of the main body portion 61, a first locking portion 63 and a second locking portion 64 (a pair of locking portions) which are provided on the main body portion 61 sandwiching the elastic portion 62 and engage with the fixture mounting hole 46 (hole) of the lighting mounting plate 44 provided on the shelf 28 of the showcase, and a lighting holding portion 65 which extends on the side opposite to the side on which the first locking portion 63 and the second locking portion 64 of the main body portion 61 are formed and holds the side of the shelf lighting 55. As a result, the lighting fixture 60 is fixed by engaging the first locking portion 63 and the second locking portion 64 with the fixture attachment hole 46, and the shelf lighting 55 can be fixed by holding the shelf lighting 55 in the lighting holding portion 65. Also, since the lighting fixture 60 is not fixed using screws or the like as in the past, there is no need to ensure a gap between the shelf lighting 55 and the shelf 28, and the height dimension of the shelf 28 to which the shelf lighting 55 is attached can be reduced. As a result, the thickness of the shelf 28 can be reduced, and the effective internal volume of the showcase can be increased. In addition, by engaging the first engaging portion 63 and the second engaging portion 64 with the fastener mounting hole 46, the lighting fastener 60 is fixed to the shelf 28, thereby preventing the lighting fastener 60 from coming off due to vibration, etc.

[0041] In addition, in the lighting fixture 60 in this embodiment, the first engagement portion 63 and the second engagement portion 64 (engagement portion) are provided at their tip portions with a first claw portion 63a and a second claw portion 64a (claw portion) that engage with the fixture attachment hole 46 (hole). With this, by engaging the first claw portion 63a and the second claw portion 64a with the fixture attachment hole 46, the lighting fixture 60 can be reliably fixed to the shelf board .

[0042] Moreover, in the lighting fixture 60 in this embodiment, the spacing between the lighting holders 65 is formed to be smaller than the width dimension of the shelf board lighting 55 . As a result, when the shelf board lighting 55 is attached to the lighting fixture 60, an outward force acts on the lighting holding part 65, so that the main body part 61 can be pressed against the lighting mounting plate 44. Therefore, the lighting mounting plate 44 is sandwiched between the first locking part 63, the second locking part 64 and the main body part 61, making it difficult for the first locking part 63 and the second locking part 64 to come loose.

[0043] Furthermore, in the lighting fixture 60 of this embodiment, the tip of the lighting holding portion 65 is formed with an expanded portion 66 that protrudes outward. As a result, by applying a pressing force to the lighting holding parts 65 in the direction in which they approach each other by the expanding 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 attachment hole 46. In addition, since the expansion portion 66 protrudes outward, when attaching the shelf lighting 55 to the lighting fixture 60, the lighting holding portion 65 can be deformed outward simply by pressing the shelf lighting 55 against the expansion portion 66. Therefore, the shelf lighting 55 can be easily attached to the lighting fixture 60.

[0044] Furthermore, in lighting fixture 60 in this embodiment, lighting holding portion 65 is formed with wiring holding portion 67 that extends to the side of main body portion 61 where first locking portion 63 and second locking portion 64 (locking portion) are formed. This allows the lighting wiring 68 of the shelf board lighting 55 to be bundled together without using a separate member. In addition, by applying an outward force to the lighting holding part 65, the wiring holding part 67 is moved toward the lighting mounting plate 44, making it possible to reduce the gap between the tip of the wiring holding part 67 and the fixing plate 43, and preventing the lighting wiring 68 from falling off.

[0045] (Other embodiments) As described above, the first to third embodiments have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to these, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the first to third embodiments to create new embodiments. Therefore, other embodiments will be exemplified below.

[0046] In the above embodiment, the showcase 1 has been described as an open-type showcase, but this is merely an example. The showcase 1 may be, for example, a closed-type showcase having a transparent door that closes the display room 12 from the front. Furthermore, the showcase 1 may be a storehouse for storing products.

[0047] [Configuration supported by the above embodiment] The above embodiment supports the following configurations.

[0048] (Additional Note) (Technology 1) A lighting fixture for fixing a shelf light to a shelf, the lighting fixture comprising: a main body; an elastic portion formed in a middle portion of the main body; a pair of locking portions provided on the main body portion sandwiching the elastic portion and engaging with holes provided in the shelf; and a lighting holding portion extending on the side of the main body portion opposite to the side on which the locking portions are formed and holding a side of the shelf light. According to this configuration, the light fixture is fixed by engaging the locking part with the hole, and the shelf light is held by the light holding part, so the shelf light can be fixed. Also, since the light fixture is not fixed with screws or the like as in the past, there is no need to ensure a gap between the shelf light and the shelf, and the height dimension of the shelf with the shelf light attached can be reduced. As a result, the thickness of the shelf can be reduced, and the effective internal volume of the storage cabinet can be increased. In addition, since the lighting fixture is fixed to the shelf by engaging the locking portion with the hole, it is possible to prevent the lighting fixture from coming off due to vibration or the like.

[0049] (Technology 2) The lighting fixture according to Technology 1, wherein the engaging portion has a claw portion at its tip that engages with the hole. According to this configuration, the lighting fixture can be securely fixed to the shelf board by engaging the claw portion with the hole.

[0050] (Technology 3) The lighting fixture according to Technology 1 or Technology 2, wherein the spacing between the lighting holders is smaller than the width dimension of the shelf lighting. With this configuration, when the shelf lighting is attached to the lighting fixture, an outward force acts on the lighting holding part, which presses the main body against the lighting mounting plate. Therefore, the lighting mounting plate is sandwiched between the locking part and the main body, making it difficult for the locking part to come loose.

[0051] (Technology 4) The lighting fixture according to any one of Technology 1 to Technology 3, wherein an expanded portion protruding outward is formed at a tip of the lighting holding portion. According to this configuration, by applying a pressing force to the light holding parts in a direction in which they approach each other using the expanding part, the elastic part can deform the light fixture, so that the locking part can easily engage with the fixture attachment hole. In addition, because the expansion portion protrudes outward, when attaching the shelf lighting to the lighting fixture, the lighting holding portion can be deformed outward simply by pressing the shelf lighting against the expansion portion, making it easy to attach the shelf lighting to the lighting fixture.

[0052] (Technology 5) The lighting fixture according to any one of Technology 1 to Technology 4, wherein the lighting holding portion is formed with a wiring holding portion extending to a side of the main body where the locking portion is formed. With this configuration, the lighting wiring for the shelf lighting can be bundled together without using a separate member. Also, by applying an outward force to the lighting holder, the wiring holder moves toward the lighting mounting plate, reducing the gap between the tip of the wiring holder and the fixing surface, and preventing the lighting wiring from falling off.

[0053] (Technology 6) A storage facility having a lighting fixture according to any one of Technology 1 to Technology 5 on a shelf, and shelf lighting attached to the lighting fixture. According to this configuration, the lighting fixture is fixed by engaging the locking portion with the fixture attachment hole, and the shelf lighting is held by the lighting holding portion, so the shelf lighting can be fixed. Also, since the lighting fixture is not fixed using screws or the like as in the past, there is no need to ensure a gap between the shelf lighting and the shelf, and the height dimension of the shelf with the shelf lighting attached can be reduced. As a result, the thickness of the shelf can be reduced, and the effective internal volume of the storage cabinet can be increased. In addition, since the lighting fixture is fixed to the shelf by engaging the locking portion with the fixture attachment hole, it is possible to prevent the lighting fixture from coming off due to vibration or the like. In addition, an outward force acts on the lighting holder, pressing the main body against the lighting mounting plate. This causes the lighting mounting plate to be sandwiched between the locking portion and the main body, making it difficult for the locking portion to come loose. [Industrial Applicability]

[0054] The present disclosure relates to a lighting fixture that can fix shelf lighting without increasing the height dimension of the shelf, and can be suitably used in storage facilities such as showcases that require shelf lighting. [Explanation of symbols]
