The pair of left and right support frame members 7 are supported by a pair of support columns 4a and 4b in the front and rear direction of the shelf depth direction. And the fluorescent lamp type lighting fixture 5 is attached to the lower side of each rod-shaped hollow frame material 6 in the direction in which the length direction becomes parallel to the length direction of the rod-shaped hollow frame material 6.

  Hereinafter, a specific structure will be described with reference to FIGS. 2B to 5. The rod-like hollow frame member 6 uses a lip-shaped groove member having a substantially square cross section, and is continuous over the entire length between the lip portions 6 a and 6 b. The opening 6c is used in a direction that opens horizontally and horizontally. The support frame member 7 is continuously provided from the lower side of the outer plate 8a which is adjacent to the rod-shaped hollow frame member 6 among the U-shaped section 8 which is open on the lower side and the inner and outer side plates 8a and 8b of the section U-shaped section 8. The supporting horizontal plate portion 8c and the vertical plate portion 8d connected upward from the end side of the supporting horizontal plate portion 8c are arranged, and the end portion of the rod-shaped hollow frame member 6 is formed on the vertical plate portion 8d. A notch recess 9 to be fitted is formed. At the upper end of one side edge of the notch recess 9, an engaging projection piece 9a that protrudes into the opening 6c of the rod-shaped hollow frame member 6 and is adjacent to the lower lip 6a protrudes. And the cross-sectional U-shaped part 8 is crossed so that it may continue over the upper end part of the outer side board 8a of the cross-sectional U-shaped part 8, the upper surface board 8e, and the inner side board 8b whose width | variety is smaller than the outer side plate 8a. An opening 10 is provided corresponding to each notch recess 9. The rod-shaped hollow frame member 6 may have a cross-sectional shape without a lip portion on the upper side, as shown in FIG. 4B.

  At both ends of the support frame member 7, mounting plate portions 11 that are in contact with the side surfaces of the support columns 4 a and 4 b are continuously provided from the outer plate 8 a of the cross-section U-shaped portion 8. By engaging the pair of downward locking pieces 11a with the locking holes 12 provided on the side surfaces of the columns 4a and 4b, the support frame member 7 is horizontally placed at a predetermined height between the pair of front and rear columns 4a and 4b. It is built in. In this way, when the pair of left and right support frame members 7 are installed at the same level, a plurality of (four in the illustrated example) rod-like hollow frame members 6 are arranged in parallel to the shelf front direction and the openings thereof. Both ends are fitted into the notch recesses 9 of the pair of left and right support frame members 7 so as to open horizontally in the horizontal direction, and are supported horizontally. As a result, the lower side surfaces of both end portions of each rod-shaped hollow frame member 6 are supported by the supporting horizontal plate portion 8c of the support frame member 7, and the upper surface of the rod-shaped hollow frame member 6 and the upper surface plate 8e of the cross-section U-shaped portion 8 are supported. The upper surface is continuous with the upper surface, and the end opening of the rod-shaped hollow frame member 6 is closed by the outer plate 8 a of the cross-sectional U-shaped portion 8 of the support frame member 7.

  As described above, shelves 2A and 2B are formed by laying four rod-shaped hollow frame members 6 arranged in parallel at equal intervals in the shelf depth direction between the pair of left and right support frame members 7. However, the pair of front and rear support columns 4a and 4b at the intermediate position includes a support frame member 7 on the side adjacent to the shelf 2B of one shelf 2A, and a support frame member 7 on the side adjacent to the shelf 2A of the other shelf 2B. However, they are supported in parallel at the same level so that the inner plates 8b of the U-shaped cross-sections 8 of the support frame members 7 are adjacent to each other. In other words, the width of the U-shaped section 8 of each support frame member 7 is set so that the two support frame members 7 can be installed between the pair of front and rear columns 4a and 4b. In addition, between the support columns 4a, 4a and 4b, 4b forming the left and right pairs, the front-end connecting frame members 14a, 14b are installed at the same level as the lowermost shelves 1A, 1B and the uppermost shelves 3A, 3B. Has been.

  The fluorescent lamp type lighting fixture 5 is a conventionally well-known one in which a reflective cover 5b and a fluorescent lamp 5c are attached to a long box-shaped main body 5a, and a plurality of locations in the length direction of the bottom plate portion of the main body 5a (for example, 2), circular mounting seats 5d project from the center of the mounting seat 5d outwardly from the inside by means of mounting screws 5e below the rod-shaped hollow frame members 6 of the shelves 2A and 2B. Mounted on the side. Accordingly, a screw hole 6d for screwing the mounting screw 5e is provided in a predetermined position on the lower surface of each rod-shaped hollow frame member 6 in advance, or when a tapping screw is used for the mounting screw 5e. A pilot hole can be provided. Of course, the number and arrangement of the mounting screws 5e for attaching the main body 5a of the lighting fixture 5 to the lower surface of the rod-like hollow frame member 6 can be freely set, and a mounting structure that does not use the mounting screws 5e can also be adopted.

  If the lighting fixture 5 is attached to the lower surface of each rod-shaped hollow frame member 6 of the shelves 2A and 2B as described above, the power cord 5f extending from the main body 5a of the lighting fixture 5 is connected to the lighting fixture 5 The rod-shaped hollow frame member 6 is housed in the rod-shaped hollow frame member 6 from the opening 6c of the rod-shaped hollow frame member 6 to which the main body 5a of the instrument 5 is attached, and passes through the rod-shaped hollow frame member 6 to pass through the rod-shaped hollow frame member 6. The support frame from the opening 10 (opening portion formed at the upper end of the outer plate 8a of the cross-sectional U-shaped portion 8 of the opening 10) formed in the cross-sectional U-shaped portion 8 of the support frame member 7 supporting one end of the support frame. It can be led to the inside of the U-shaped section 8 of the material 7. Finally, the power cord 5f can be guided downward from one end of the support frame member 7 along the support column 4a or 4b and extended out of the rack. When 2B is erected so as to be continuous in the shelf front direction at the same level, as shown in phantom lines in FIG. 3, the power cord 5f of each lighting fixture 5 of one shelf 2A (or 2B), The rod-shaped hollow of the other shelf 2B (or 2A) is passed from the opening 10 of the support frame member 7 of the shelf 2A (or 2B) through the opening 10 of the support frame member 7 of the other shelf 2B (or 2A). It is also possible to guide into the frame member 6 and converge it to one end portion in the rack front direction via the inside of the rod-like hollow frame member 6 of the other shelf 2B (or 2A).

  When the power cord 5f of the luminaire 5 is extended from the bottom surface of the main body 5a, a gap is formed between the bottom surface of the main body 5a secured by the mounting seat 5d and the lower side surface of the rod-shaped hollow frame member 6. The power cord 5f is once led to the lateral side of the rod-shaped hollow frame member 6 as shown in FIG. 6, but the power cord 5f is attached to the lower plate portion of the rod-shaped hollow frame member 6 as shown in FIG. When the opening 13 for introduction into the hollow frame member 6 is provided, not only the work of introducing the power cord 5f into the rod-shaped hollow frame member 6 is facilitated but also the mounting seat 5d is not provided. Thus, the bottom surface of the main body 5a can be directly attached to the lower surface of the rod-like hollow frame member 6. Of course, the lighting fixture 5 in which the power cord 5f extends from the lateral side surface of the main body 5a can also be used.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 7 to 9. In this embodiment, a roller rail 15 for sliding the plant cultivation container C in the shelf front direction is incorporated in the shelf 16. ing. The structure of the shelf 16 is illustrated only in that the number of the rod-like hollow frame members 6 used is larger because the width in the depth direction of the shelf is larger than the shelves 2A and 2B in the previous embodiment. Although there is no, it is basically the same including the processing of the power cord 5f of the lighting fixture 5 attached to each rod-like hollow frame member 6.

  The roller rail 15 is a conventionally well-known one that is supported by a rail main body 15a so that the roller 15b can be rotated at equal intervals. The rail main body 15a has substantially the same length as the entire length of the rod-shaped hollow frame member 6. It is. The roller rail 15 is installed between two adjacent rod-shaped hollow frame members 6 of the shelf 16 in a direction parallel to the shelf front direction. At this time, as shown in FIG. 7 and FIG. 8A, the roller rails 15 can be installed between two adjacent rod-shaped hollow frame members 6 at appropriate intervals, as shown in FIG. A roller rail 15 can be installed between two adjacent rod-shaped hollow frame members 6.

  Thus, both ends of each roller rail 15 are adjacent to the outer plate 8a in the cross-section U-shaped portion 8 of the pair of left and right support frame members 7 located at both ends of the shelf 16 in the frontage direction. It is supported on the upper side of the vertical plate portion 8d. In this state, the support level of each roller rail 15 is determined, but the position of the shelf 16 in the depth direction is not determined. Therefore, as shown in FIGS. Further, the positioning / supporting member 17 for the roller rail 15 can be disposed. The positioning and supporting member 17 is engaged between the rod-shaped hollow frame members 6 on both sides of the roller rail 15, and the engaging step portions 17 a and 17 b at both ends are engaged with the sides of the rod-shaped hollow frame member 6. The rail main body 15a of the roller rail 15 is fitted in the center portion and is provided with a supporting concave portion 17c. Reference numerals 17d and 17e denote reinforcing plates for suppressing downward deformation of the positioning / supporting member 17. Further, a vibration-proof elastic material such as rubber can be sandwiched between the engaging step portions 17 a and 17 b at both ends of the positioning and supporting member 17 and the rod-shaped hollow frame member 6.

  According to the said structure, the container C for plant cultivation mounted on the shelf 16 is not directly supported by the rod-shaped hollow frame material 6, but by the roller rail 15 (roller 15b) in parallel of a shelf depth direction. Since it is supported, the roller 15b of each roller rail 15 can be slid lightly and easily in the frontage direction of the shelf 16 using the rolling of the roller 15b. In this case, as shown in FIGS. 7 and 8, guide bars 18 a and 18 b for restricting the movement path in the shelf front direction of the plant cultivation container C on the front and rear sides in the depth direction of the shelf 16 at a position appropriately above the shelf 16. Can be erected. The guide bars 18a and 18b can be attached at both ends to the pair of front and rear columns 4a and 4b by the same mounting structure as the mounting structure of the support frame member 7 to the columns 4a and 4b. That is, a mounting plate portion 19 that is in contact with the side surfaces of the support columns 4a and 4b is fixedly connected to both ends of the guide bars 18a and 18b, and a pair of upper and lower downward locking pieces provided on the mounting plate portion 19 are connected to the support column. By engaging with the locking holes 12 provided on the side surfaces of 4a and 4b, guide bars 18a and 18b are installed horizontally at a predetermined height between the right and left columns 4a and 4a and between 4b and 4b. can do.

  In the above example, since both ends of the rail body 15a of the roller rail 15 are supported by the upper side of the vertical plate portion 8d of the support frame member 7, from the upper surface of the shelf 16, that is, from the upper surface of the rod-shaped hollow frame member 6. While the protrusion height of the roller 15b is increased, it is essential to use a means (positioning and supporting member 17) for positioning the roller rail 15 in the shelf depth direction. However, as shown in FIG. When both ends of the rail body 15a of the roller rail 15 are fitted to and supported by the support recess 20 formed in the vertical plate portion 8d, the roller 15b protrudes from the upper surface of the shelf 16 (the upper surface of the rod-shaped hollow frame member 6). When the height of the roller rail 15 is short, the positioning and supporting member 17 that supports the middle of the roller rail 15 is also unnecessary.

  The plant cultivation rack of the present invention is used to grow a plurality of plant cultivation containers indoors, that is, under a lighting condition by using a flat container in which seedlings of cultivated plants are planted or sown in a filled soil. It can be used as a rack with lighting equipment.
