Description

  The present invention is provided in a display room in which a shelf for displaying merchandise is laid, a see-through door that can be opened and closed so as to be openable and closable, and an opening of the display room. The present invention relates to a support case and a showcase in which an illuminating device is attached to the rear surface of the support column.

  Conventionally, in this type of showcase, the main body is constituted by a heat insulating box having a substantially U-shaped cross-section with an open front, and a display chamber is formed in which a plurality of product display shelves are erected. . At the front part of the heat insulation box, a plurality of support columns are erected on the left and right sides and at a predetermined distance from both sides. Between each support | pillar, the door which can see through the inside which obstruct | occludes the front opening of a display chamber so that opening and closing is possible is provided. The door is supported by a support column so that one end of the door can be rotated, and can be opened by rotating about the one side (see, for example, Patent Document 1 and Patent Document 2).

  And the fluorescent lamp for display room illumination is installed in the rear surface of this support | pillar over the upper and lower sides. Thereby, the product displayed and stored on the shelf in the display room is illuminated by the fluorescent lamp.

  Here, the light emitted from the fluorescent lamp is diffused from the outer surface of the fluorescent tube constituting the fluorescent lamp to illuminate the display room. Since the light from the fluorescent lamp diffuses toward the display room, it is not possible to irradiate a sufficient amount of light up to the front center of the shelf. Therefore, there is a problem that the products displayed around the center of the shelf are not supplied with a sufficient amount of light and become darker than others.

  Therefore, recently, an illuminating device using a highly directional LED element has been adopted in place of the fluorescent lamp. Such an illuminating device is composed of, for example, a substrate on which a plurality of chip-type LED elements are arranged. And the board | substrate with which the said LED element was provided is attached across the front corner corner part of a display chamber up and down. At this time, the substrate is attached so as to form a predetermined angle with respect to the rear surface of the support column, whereby the light from the LED element is directly applied to the front part of the shelf.

Similarly, support columns provided at predetermined intervals from the front corners of the display room are provided up and down in a state where lighting devices including substrates on which such LED elements are provided are back-to-back. The LED element of one lighting device irradiates light toward the front of the shelf located in the display room on one side of the column (one side in the left-right direction), and the LED element of the other lighting device It was set as the structure which irradiates light toward the shelf front part located in the display room of the side (other side of the left-right direction).

The highly directional light emitted from the LED element 17 irradiated toward the rear in the chamber 5 is reflected in the reflecting member 25 a plurality of times, thereby effectively displaying the display chamber on the other side in the horizontal direction of the column 8. It is possible to irradiate (reflect) toward the front part of the shelf 9 located in 5.

  And each reflection member 24 and 25 is each provided corresponding to each LED element 17 provided in the board | substrate 18, These are arrange | positioned so that it may become alternate in an up-down direction. At this time, the center of the first reflecting member 24 is one side in the horizontal direction of the substrate 18, that is, the side on which the opening for irradiating irradiated light (reflected light) to the display chamber 5 side is formed. Then, they are arranged so as to be biased to the right side from the front of the showcase 1. Then, the second reflecting members 25 arranged alternately with respect to the reflecting member 24 are centered at the other side in the horizontal direction of the substrate 18, that is, irradiated light (reflected light) is irradiated to the display chamber 5 side. In the present embodiment, on the side where the opening is formed, the showcase 1 is arranged so as to be biased to the left side from the front.

  Therefore, as shown in FIG. 5 and FIG. 8, each LED element 17 can be arranged at the back of each reflecting member 24, 25 and is irradiated from the LED element 17 toward the rear in the display chamber 5. Most of the light having a high directivity is reflected by the reflecting surfaces 24A and 25A of the reflecting members 24 and 25 (a plurality of times depending on the angle), and the shelves 9 located in the display chambers 5 corresponding to the reflecting surfaces 24A and 25A. Can be irradiated toward the front. Therefore, compared with the case where the light from the LED element 17 is irradiated directly toward the irradiation target, the control ability (direction of light) of the light reflection direction can be improved, and more effective illumination is realized. be able to.

  Moreover, by setting it as the said structure, on each single board | substrate 18, as shown in FIG. 8, the several LED element 17 ... arrange | positioned on the substantially up-down direction and each LED element 17 each. On the other hand, reflecting members 24 and 25 that perform illumination by reflecting the irradiation light from the LED elements 17 in so-called zigzag different directions are arranged.

  At this time, when the reflecting surfaces 24A and 25A formed on the inner surfaces of the reflecting members 24 and 25 are configured in substantially the same manner, each display is performed in a state where the irradiation light (reflected light) is shifted in the vertical direction in the horizontal direction (left and right). Irradiation is directed toward the front of the shelf 9 of the chamber 5.

  Therefore, in the present embodiment, the reflective surfaces 24A and 25A of the reflecting members 24 and 25 are substantially equal in brightness in the vertical direction on one side and the other side (left and right sides) in the horizontal direction of the LED illumination members 16. It is assumed that the curved shapes of the reflecting surfaces 24A and 25A and the respective inclination angles composed of a plurality of inclined surfaces are determined in accordance with the respective mounting positions.

  Thereby, the brightness (light quantity or light irradiation amount) in the vertical direction on one side and the other side of the LED illumination member 16 can be made substantially uniform with no unevenness, as shown by the dotted line in FIG. The lighting effect can be improved.

  In this case, the reflecting members 24 and 25 have different shapes of the reflecting surfaces 24A and 25A depending on their mounting positions. In this embodiment, as shown in FIG. 6 and FIG. 24... Are integrally formed by connecting sides 27..., And the reflecting members 25. Thereby, it becomes possible to attach the reflecting members 24 and 25 corresponding to the respective appropriate positions.

  On the other hand, the cover member 26 is composed of a rectangular body made of a translucent material so as to cover the substrate 18, the LED element 17, and the reflection members 24 and 25 from the outside. The front surface of the cover member 26 is opened, and an engaging claw 29 for detachably holding the reflecting members 24 and 25 inserted from the opening side and the substrate 18 is formed on the inner edge of the opening. .

  In this embodiment, the cover member 26 has attachment pieces for fixing the cover member 26 holding the substrate 18 and the like to the rear surface 8A of the column 8 by screwing at the upper and lower ends of the cover member 26. And is integrally formed. In addition, the said attachment piece is abbreviate | omitted in FIG.6 and FIG.7.

  That is, as shown in FIGS. 3 and 4, the upper end of the opening edge of the cover member 26 that contacts the rear surface 8A of the column 8 extends upward from one side in the horizontal direction (in this case, the left side in FIG. 3). The upper mounting piece 20 is formed. A lower mounting piece 21 is formed at the lower end of the opening edge so as to extend downward from the other side in the horizontal direction (in this case, the right side in FIG. 3).

  At this time, the upper mounting piece 20 and the lower mounting piece 21 are formed to extend at positions that do not overlap in the vertical direction, and are used for fixing to the support column 8 in each of the mounting pieces 20 and 21. Screw holes 20A and 21A for the purpose are formed.

  Further, a concealing wall 22 for concealing the mounting piece 20 from the side is provided on one side of the upper mounting piece 20 (in this case, the left side as viewed in FIG. 3) and the side surface of the cover member 26 on the one side. It is formed to be flush with each other. Similarly, a concealing wall 23 that conceals the mounting piece 21 from the side is provided on the other side of the lower mounting piece 21 (in this case, the right side as viewed in FIG. 3). And are formed so as to be flush with each other.

  With this configuration, the assembly procedure and attachment procedure of the LED illumination member 16 in this embodiment will be described. First, a plurality of integrally formed reflecting members 24 and a plurality of integrally formed reflecting members 25 are disposed on the surface of the substrate 18 on which the LED elements 17 are disposed. And the cover member 26 is coat | covered from the said reflection member 24,25 side with respect to the board | substrate 18, and each reflection member 24,25, LED element 17, and the board | substrate 18 are included in the said cover member 26. FIG.

  At this time, the inner dimension of the cover member 26 is a state in which the board 18 and the reflection members 24 and 25 are substantially accommodated in the cover member 26 in consideration of the thickness of the substrate 18 and the depth dimensions of the reflection members 24 and 25. Thus, the engaging claw 29 formed on the inner edge of the opening of the cover member 26 is configured to be engaged with the surface of the substrate 18 that faces the surface on which the LED elements 17 are disposed. With this configuration, the LED lighting member 16 can be easily assembled.

  The assembled LED illuminating member 16 abuts the opening side (surface on the substrate 18 side) of the cover member 26 against the rear surface 8A of the support column 8 to which the illuminating device 15 is attached, and mounting pieces formed on the upper and lower ends of the cover member 26. 20 and 21 are fixed to the rear surface 8A of the support column 8 with screws (fixing tools) 31 and 31.

  The illuminating device 15 is attached to the rear surface 8 </ b> A of the support column 8 by arranging a plurality of LED illumination members 16 side by side in the vertical direction. In this case, the cover member 26 of one LED illumination member 16, for example, the upper mounting piece 20 of the cover member 26 of the LED illumination member 16 located on the lower side, and the cover member 26 of the other LED illumination member 16, in this case on the upper side It becomes possible to overlap with the lower mounting piece 21 of the cover member 26 of the LED illumination member 16 located in the horizontal direction (in parallel) and to fix to the support column 8.

  Therefore, adjacent LED illumination members 16 and 16 can be arranged in series closer to each other in the vertical direction. Accordingly, it is possible to improve the continuity of the brightness (light quantity, irradiation amount) of the illumination that passes through the cover member 26 by the LED illumination members 16 constituting the illumination device 15.

  In particular, as in this embodiment, when the LED elements 17 serving as light sources for irradiating light in different directions are alternately arranged, only the LED elements 17 for irradiating light only in one direction are provided. Although the continuity of illumination is reduced as compared with the case of a fluorescent lamp, the continuity of illumination transmitted through the cover member 26 is improved by arranging the adjacent LED illumination members 16 closer in the vertical direction as described above. This makes it possible to achieve appropriate lighting.

  Moreover, the cover member 26 which comprises each LED illumination member 16 is fixed to 8 A of support | pillar rear surfaces with the upper attachment piece 20 extended and formed in the upper direction, and the lower attachment piece 21 formed extended in the downward direction. Therefore, the width dimension of the illuminating device 15 itself in consideration of the attachment can be reduced, and the illuminating device 15 can be attached without increasing the width dimension of the support rear surface 8A according to the width dimension of the illuminating device 15. It becomes possible. Thereby, the display effect can be improved.

  In the present embodiment, concealment walls 22 and 23 for concealing the attachment pieces 20 and 21 are formed on one side of the upper attachment piece 20 and the other side of the lower attachment piece 21. When the lighting device 15 is viewed from the side, the mounting pieces 20 and 21 in the portion where the LED lighting members 16 are adjacent to each other are concealed by the respective concealing walls 22 and 23, that is, one side of the lighting device 15 (in FIG. The left side is concealed by the concealing wall 22, and the other side (right side in FIG. 3) is concealed by the concealing wall 23. Thereby, the continuity of each LED illumination member 16 and 16 can be improved, and aesthetic improvement can be aimed at.

  In addition, lighting devices (not shown) are provided at the corners on both front sides of the display chamber 5 in the vertical direction. Such an illuminating device is configured in substantially the same manner as the illuminating device 15 provided on the rear surface 8 </ b> A of the column 8, reduces the number of LED elements 17 provided on the substrate 18, and faces the front part of the shelf 9 positioned in the display chamber 5. The reflection member 24 or 25 that reflects the light may be provided.

  Thereby, it becomes possible to illuminate the front part of the shelf 9 located in the display chamber 5 that exists only on one side (or the other side) in the horizontal direction with respect to the lighting device. Note that the illumination devices provided at the corners of the front both sides are not limited to the dimensions of the rear surface 8A of the support column 8 and are only limited to illuminate in one direction. The substrate 18 on which the LED elements 17 are provided in the vertical direction may be arranged to form a predetermined angle with respect to the corner angle, as in a conventional manner.

  With this configuration, light from each LED element 17 disposed on the substrate 18 attached substantially parallel to the rear surface 8 </ b> A of the support column 8 is irradiated toward the rear in the display chamber 5. Since each LED element 17 is provided correspondingly with the first reflecting member 24 or the second reflecting member 25, the irradiation light from the LED element 17 provided with the first reflecting member 24 is The light is reflected once or a plurality of times on the reflecting surface 24 </ b> A, passes through the cover member 26, and is irradiated toward the front portion of the shelf 9 located in the display chamber 5 on one side in the horizontal direction of the column 8. Further, the irradiation light from the LED element 17 provided with the second reflecting member 25 is reflected once or a plurality of times on the reflecting surface 25A, passes through the cover member 26, and other in the horizontal direction of the support column 8. Irradiation is directed toward the front of the shelf 9 located in the side display chamber 5.

  Similarly, the front part of the shelf 9 located in the display room 5 is illuminated from both side parts of the display room 5 by the lighting devices disposed at the corners of the front side parts of the display room 5. As a result, the front part of the shelf 9 on which the commodity located in the display room 5 is placed is directed to one side and the other side in the horizontal direction of the column 8 by the lighting device 15 provided on the rear surface 8A of the column 8. It is possible to illuminate with the light irradiated and the light irradiated from the lighting device provided at the corners on both front sides of the display room 5, thereby improving the lighting effect of the products in the display room 5 and the showcase itself. be able to.

  In particular, in the configuration of the present invention, since the reflecting members 24 and 25 are alternately arranged in the vertical direction as described above, one side and the other in the horizontal direction of the column 8 from the rear surface 8A of the column 8 are arranged. It is possible to irradiate the front part of the shelf 9 located in the display chamber 5 in different directions (both sides in the horizontal direction of the support column 8) with a uniform amount of light.

  Moreover, in a present Example, the irradiation light from the several highly directional LED element 17 arrange | positioned on the single board | substrate 18 can be irradiated in a different direction, and the goods on the shelf 9, especially the forefront part are used. It is possible to illuminate well, and the illumination effect can be improved.

  Furthermore, since the light emitted from the LED element 17 toward the rear in the display chamber 5 is reflected toward the front part of the corresponding shelf 9 by the respective reflecting members 24 and 25, it is directly targeted.
