DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] (The knowledge and other information that formed the basis of this disclosure) At the time the inventors came up with the idea of ​​this disclosure, showcases had a shelf structure that held the wiring of the lighting equipment, which had passed through a guide groove and been guided, in a state where it was inserted into the retaining hole of the lighting mounting member. However, in the conventional technology, although it is possible to hold the wiring near the lighting mounting member by the holding hole, in order to hold the wiring from the lighting mounting member to the rear part of the shelf board, it is necessary to attach a separate wiring fastener or wiring connector holder, which may increase the number of parts and the installation labor. In addition, the inventor discovered that using such wiring fasteners increases the number of unnecessary protrusions from the shelf board, which may cause problems such as items placed on the shelf board getting caught or workers getting injured, and in order to solve this problem, the inventor came to constitute the subject of the present disclosure. Therefore, the present disclosure provides a shelf and storage unit that can support lighting wiring without slack, without using separate components.

[0025] [1-1-2. Configuration of shelf lighting] A shelf light 55 is provided on the underside of the tip of the shelf. The shelf lights 55 are lighting devices located inside the display room 12. The shelf lights 55 are attached to the front of each shelf 28. The shelf lights 55 are attached to the underside of each shelf 28. The shelf lights 55 are lighting devices such as LEDs, fluorescent lights, or incandescent light bulbs. The shelf lights 55 emit light downward and backward. The shelf lights 55 illuminate the inside of the display room 12.

[0026] Fig. 2 is a perspective view showing the underside of the shelf board, Fig. 3 is a plan view showing the underside of the shelf board, and Fig. 4 is a cross-sectional view of the front end portion of the shelf board. 2, shelf board 28 is made of a plate-like member such as sheet metal. A downwardly extending flange portion 40 is formed around shelf board 28. Two reinforcing ribs 41a, 41b extending in the width direction are attached to the underside of 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.

[0027] 4, 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 28. 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.

[0028] 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 .

[0029] 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. As shown in Fig. 4, the lighting fixture 60 has a plate-shaped main body 61. A substantially U-shaped elastic portion 62 is formed from the middle of the main body 61 toward one end of the main body. The main body 61 is configured such that both end portions can approach each other in the length direction in Fig. 3 due to the elastic portion 62. The elastic portion 62 of the main body portion 61 is formed with a first locking portion 63 that protrudes toward the end side of the main body portion 61 . The main body 61 is provided at an end opposite to the end where the first locking portion 63 is formed with a second locking portion 64 that protrudes toward the end of the main body 61 .

[0030] 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 locking portion 63 and the second locking portion 64 are formed. The lighting holders 65 are formed in a generally L-shape extending diagonally downward from both ends of the main body 61, and an expansion portion 66 that expands outward is formed at the tip of the lighting holder 65. A wiring holder 67 is formed in the middle of the lighting holder 65, extending to the side of the main body 61 where the first locking portion 63 and the second locking portion 64 are formed, and holds the lighting wiring 68.

[0031] As shown in FIG. 4, 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.

[0032] Here, the distance between the two lighting holding parts 65 is formed slightly smaller than the width dimension 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.

[0033] [1-1-2. Wiring structure for shelf lighting] Fig. 5 is a side view showing a part of a side surface 100 of the reinforcing rib. In Fig. 5, an opposite side surface 101 of the reinforcing rib is shown by a dashed line. 5, a wire insertion opening 70 is formed on each of both side surfaces of the two reinforcing ribs 41a, 41b. The wire insertion openings 70 are formed at the same position in the width direction of the reinforcing rib 41. A wire insertion groove 71 is formed in the wire insertion opening 70 formed on one surface (surface 100 facing the lighting mounting member) of the reinforcing rib 41a, extending from one lower end of the wire insertion opening 70 in the width direction of the reinforcing rib 41a and then extending upward. A wire support part 72 is provided at the upper end of the wire insertion groove 71, extending toward the wire insertion opening 70. A protrusion 73 protruding upward is formed at the boundary between the wire support part 72 and the wire insertion groove 71.

[0034] The wiring insertion opening 70 formed on the opposite surface 101 of the reinforcing rib 41 has a wiring insertion groove 71, a wiring support portion 72 and a protrusion 73 formed on one surface, each of which is formed in a line symmetrical manner with the wiring insertion groove 71, the wiring support portion 72 and the protrusion 73 formed on one surface. By positioning the wiring support portion 72 in this manner, the wiring support portion 72 is configured to be positioned at a shifted position in the width direction of the shelf board 28 between the wiring holding portion 67 of the lighting holding portion 65 and the rear of the shelf board 28.

[0035] [1-2. Effect] Next, the operation of the present disclosure will be described. FIG. 6 is a diagram showing how lighting wiring is arranged on the underside of the shelf board. As shown in Figures 4 and 6, first, the first locking portion 63 and the second locking portion 64 of the lighting fixture 60 are inserted and engaged with the fixture mounting hole 46 of the lighting mounting member, and the lighting fixture 60 is attached to the lighting mounting member 42.

[0036] 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.

[0037] 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.

[0038] The lighting wiring 68 held by the wiring holding portion 67 is inserted from the lighting mounting plate into the wiring insertion opening 70 of the reinforcing rib 41a, as shown in Fig. 6. The lighting wiring 68 inserted into the wiring insertion opening 70 is held by the wiring support portion 72 via the wiring insertion groove 71. At this time, since the protrusion 73 is formed at the boundary between the wire insertion groove 71 and the wire support portion 72, it is possible to prevent the lighting wire 68 from coming off the wire support portion 72.

[0039] The lighting wiring 68 is disposed obliquely at a predetermined angle from the wiring holding portion 67 to the width direction of the reinforcing rib 41a while being supported by the wiring support portion 72. This allows a constant tension to be applied to the lighting wiring 68.

[0040] Next, the lighting wiring 68 is supported by the wiring support portion 72 through the wiring insertion groove 71 from the wiring insertion opening 70 formed in the side surface 101 on the opposite side of the reinforcing rib 41a. The wiring support portions 72 formed on both side surfaces of the reinforcing rib 41a are formed line-symmetrically with respect to the wiring insertion opening 70, so that the lighting wiring 68 is arranged obliquely in opposite directions inside the reinforcing rib 41.

[0041] Similarly, the lighting wiring 68 is supported by the wiring support portion 72 via the wiring insertion opening 70 and the wiring insertion groove 71 of the other reinforcing rib 41b. The lighting wiring 68 supported by the wiring support portion 72 of the other reinforcing rib 41b is connected to a predetermined wiring location from the rear of the shelf board 28. In this case, the lighting wiring 68 is also disposed obliquely with respect to the width direction of the reinforcing rib 41b between the wiring support portion 72 of the reinforcing rib 41b and the rear of the shelf board 28. In this way, the lighting wiring 68 is supported from the wiring holding portion 67 of the lighting fixture 60 to the wiring support portions 72 of the reinforcing ribs 41a, 41b, respectively, so that the lighting wiring 68 is routed in a zigzag manner at a predetermined angle between the wiring support portions 72. This makes it possible to apply a certain tension to the lighting wiring 68, and to prevent the lighting wiring 68 from sagging.

[0042] Furthermore, when the wiring connector 69 is inserted midway through the lighting wiring 68, the wiring connector 69 is disposed so as to be located inside the reinforcing rib 41a. By disposing the wiring connector 69 inside the reinforcing rib 41a in this manner, it is not necessary to attach a separate connector support to the shelf board 28. The wiring connector 69 may be disposed inside the reinforcing rib 41b.

[0043] [1-3. Effects, etc.] As described above, in the present embodiment, the underside of the shelf 28 is provided with reinforcing ribs 41a, 41b extending in the width direction of the shelf 28, and wiring support portions 72 that support the lighting wiring 68 are provided on the sides of the reinforcing ribs 41a, 41b, and the wiring support portions 72 are positioned so as to be shifted in the width direction of the shelf 28 between the shelf lighting 55 and the rear of the shelf 28. As a result, by arranging the wiring support parts 72 at positions shifted in the width direction of the shelf board 28 between the shelf board lighting 55 and the rear part of the shelf board 28, the lighting wiring 68 between the wiring support parts 72 is routed in a zigzag state at a predetermined angle to each other. Therefore, a certain tension can be applied to the lighting wiring 68, and slackness of the lighting wiring 68 can be suppressed without using a separate member. As a result, since separate parts are not required, the number of parts and installation labor can be reduced. Furthermore, unnecessary protrusions from the shelf 28 can be suppressed, preventing items placed on the shelf 28 from getting caught and preventing workers from getting injured.

[0044] Furthermore, in the shelf board in this embodiment, wire insertion openings 70 are provided on both side surfaces of reinforcing ribs 41a, 41b, and wire insertion grooves 71 continuing to wire support portions 72 are provided in wire insertion openings 70. As a result, the lighting wiring 68 can be easily supported by the wiring support part 72 by simply inserting the lighting wiring 68 through the wiring insertion opening 70 and hooking it onto the wiring support part 72 via the wiring insertion groove 71.

[0045] In addition, in the shelf board in this embodiment, the wiring insertion opening 70 is provided at approximately the same position in the width direction of the reinforcing ribs 41a, 41b, and the wiring insertion groove 71 and the wiring support portion 72 formed on both side surfaces 100, 101 of the reinforcing ribs 41a, 41b are formed linearly symmetrically with respect to the wiring insertion opening 70. As a result, the wiring support parts 72 are positioned at staggered positions in the width direction of the shelf 28 between the shelf lighting 55 and the rear of the shelf 28, and the lighting wiring 68 between each wiring support part 72 can be supported with a constant tension, thereby preventing slack in the lighting wiring 68 without the use of additional components.

[0046] Moreover, the shelf board in this embodiment is provided with a wiring connector 69 for connecting lighting wiring 68, and the wiring connector 69 is disposed inside the reinforcing ribs 41a and 41b. In this way, by disposing the wiring connector 69 inside the reinforcing ribs 41a and 41b, it is not necessary to attach a separate connector support to the shelf board 28.

[0047] (Other embodiments) As described above, the first embodiment has been described as an example of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, 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 embodiment to create new embodiments. Therefore, other embodiments will be exemplified below.

[0048] In the above embodiment, the wiring insertion groove 71, the wiring support portion 72 and the protrusion 73 are formed so as to be symmetrical with respect to the wiring insertion opening 70 formed on both side surfaces of the reinforcing rib 41, but the present disclosure is not limited to this. For example, the positions of the wiring insertion openings 70 formed on both sides of the reinforcing rib 41 may be shifted in the width direction of the reinforcing rib 41. Also, instead of forming the positions of the wiring support parts 72 line-symmetrically with respect to the wiring insertion openings 70, the wiring support parts 72 may be formed on the same side of the wiring insertion openings 70. Furthermore, the positions of the wiring insertion openings 70 in the two reinforcing ribs 41 may be formed at different positions. Also, three or more reinforcing ribs 41 may be provided. That is, any configuration is acceptable as long as the positions of the wiring support parts 72 differ in the width direction of the reinforcing rib 41 and the lighting wiring 68 can be routed in a zigzag state at a predetermined angle to each other.

[0049] In addition, in the present 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. The showcase 1 may also be a storage unit with a door that hides the inside.
