  However, in the conventional rack frame and rack, in order to assemble one rack, it is necessary to prepare a plurality of types of rack frames. For example, in a rack using four rack frames, the same two types of rack frames can be used for the two rack frames located diagonally, but two adjacent rack frames are Since the directions are reversed, different types of rack frames must be used to align the area indication marks. Therefore, it is necessary to prepare two or more types of rack frames.

  An object of the present invention is to provide a rack frame and a rack capable of reducing the types of rack frames used for assembling one rack.

  The rack frame to be improved by the present invention includes a plurality of shelf mounting holes formed at predetermined intervals so as to form a hole array, and a plurality of rack mounting holes formed along the hole array. And a plurality of area indication marks indicating the formation area of the shelf mounting holes. In the present invention, the plurality of shelf mounting holes and the plurality of region indicating marks are formed so as to be symmetrical with respect to a virtual line passing through the center in the longitudinal direction of the rack frame and perpendicular to the longitudinal direction. Yes.

  When the rack frame is formed as in the present invention, the vertical direction is reversed when the rack frame is used as a vertical frame, and the horizontal direction is reversed when the rack frame is used as a horizontal frame. The positions of the plurality of shelf mounting holes and the plurality of area indication marks are the same. Therefore, the rack frame can be used with the vertical direction or the horizontal direction reversed, and the number of types of rack frames used for assembling one rack can be reduced. When the rack frame is used as a horizontal frame, the shelf board functions as a partition plate.

  A plurality of area indicating marks can be formed so that the number of shelf mounting holes formed in the area between two adjacent area indicating marks is equal. In this way, it is possible to easily recognize the number of shelf mounting holes from the top or the number from the bottom on the basis of the area indication mark.

  The area indicating mark can be composed of one or more through holes, protrusions, or recesses. If the area instruction mark is formed in this way, a plurality of shelf mounting holes and a plurality of area instruction marks can be formed simultaneously in one step by pressing or the like.

  The plurality of region indicating marks are preferably formed such that the number of through holes, protrusions or recesses increases or decreases as the distance from the symmetry axis increases. In this way, when the rack is assembled, the corresponding shelf mounting holes of the plurality of rack frames can be easily identified based on the number of through-holes, protrusions, or recesses constituting the region support mark. .

  The rack to be improved by the present invention includes a plurality of shelf mounting holes formed at predetermined intervals so as to form a hole array, and a plurality of shelf boards formed along the hole array. A plurality of vertical frames provided with a plurality of region indicating marks indicating the formation regions of the mounting holes, an upper connecting structure portion connected to the upper ends of the plurality of vertical frames, and connected to the lower ends of the plurality of vertical frames, respectively. And a lower connecting structure portion. In the present invention, the plurality of shelf mounting holes and the plurality of region indicating marks are formed so as to be line symmetric with respect to an imaginary line passing through the center in the longitudinal direction of the vertical frame and orthogonal to the longitudinal direction. .

  When the rack is formed as in the present invention, the positions of the plurality of shelf mounting holes and the plurality of area indicating marks are not changed even if the vertical direction of the vertical frame is reversed. Therefore, the vertical frame can be used upside down, and the types of vertical frames used to assemble one rack can be reduced. For example, in a rack that uses four vertical frames, the two adjacent rack frames are arranged upside down, and the two opposite rack frames are arranged in the same up and down direction. It is only necessary to prepare one type of vertical frame.

  The structures of the upper connection structure portion and the lower connection structure portion are arbitrary. For example, the upper connection structure portion and the lower connection structure portion may be configured by a combination of a plurality of horizontal frames, or may be integrally formed by a plate material. When the upper connection structure portion and the lower connection structure portion are each composed of one or more horizontal frames extending in a direction orthogonal to the vertical frame, the upper connection structure portion and the lower connection structure can be simply combined by combining a plurality of horizontal frames. Part can be formed.

  Of course, the outer wall material may be fixed to the outside of the rack of the present invention to constitute the housing.

  Hereinafter, a rack according to an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2 are a perspective view and a plan view of a rack according to an embodiment of the present invention applied to a rack in which, for example, an uninterruptible power supply, a DC power supply or the like is mounted. As shown in both drawings, the rack of the present embodiment includes an upper connection structure portion 1, a lower connection structure portion 3, and four rack frames 5A to 5D that constitute a vertical frame. As shown in FIG. 1, the upper connection structure portion 1 and the lower connection structure portion 3 both have the same structure, and a pair of first extensions extending in a direction orthogonal to the vertical frame (rack frames 5A to 5D). One horizontal frame 7 and a pair of second horizontal frames 9 are combined in a rectangular shape. The pair of first horizontal frames 7 and the pair of second horizontal frames 9 are formed by bending and pressing a steel plate. The pair of first horizontal frames 7 and the pair of second horizontal frames 9 are arranged in parallel so as to form a frame.

  Each of the rack frames 5A to 5D has the same structure, and connects the four corners of the rectangular upper connection structure 1 and the four corners of the rectangular lower connection structure 3 respectively. Yes. The upper connection structure 1 is connected to the upper ends of the rack frames 5A to 5D, and the lower connection structure 3 is connected to the lower ends of the rack frames 5A to 5D. The structure of the rack frames 5A to 5D will be described using the rack frame 5A shown in the perspective view of FIG. 3 as a representative example. The rack frame 5A has an elongated shape extending in the vertical direction. The rack frame 5A is formed by subjecting a steel plate to pressing and bending so as to include four continuous plate-like portions 5e to 5h. The plate-like portion 5g is formed with four attachment through holes 11, 30 shelf plate attachment holes 13, and six area instruction marks 15A to 15F. In the plate-like portion 5h adjacent to the plate-like portion 5g, four attachment through holes 17 and thirty attachment plate attachment holes 19 are formed. The four mounting through holes 11 of the plate-like part 5g are formed two at both ends in the longitudinal direction of the plate-like part 5g, and the four mounting through-holes 17 of the plate-like part 5h are Two are formed at both ends in the longitudinal direction of the shape portion 5h. As shown in FIG. 1, the rack frames 5 </ b> A to 5 </ b> D have the upper connecting structure portion 1 and the lower connecting structure portion by a rivet 21 that passes through the mounting through hole 11 and a rivet 23 that passes through the mounting through hole 17. 3 is attached. Further, the mounting plate mounting hole 19 of the plate-like portion 5h is a circular through hole, and is used for appropriately mounting a component mounting plate extending in the vertical direction.

  As shown in FIG. 3, the 30 shelf mounting holes 13 formed in the plate-like portion 5g are formed at predetermined equal intervals so as to form a hole row. The shelf mounting hole 13 is formed by a rectangular through hole into which a fixture for attaching a shelf (not shown) can be fitted, and plays a role of fixing the fixture. The six area instruction marks 15 </ b> A to 15 </ b> F are formed at equal intervals along the hole rows of the 30 shelf mounting holes 13. These area indication marks 15A to 15F are marks indicating the formation areas of the 30 shelf mounting holes 13 and are formed at adjacent positions on the plate-like portion 5f side of the 30 shelf mounting holes 13. These are constituted by small through holes. More specifically, the region designation marks 15A to 15F are formed adjacent to the third, eighth, thirteenth, eighteenth, twenty-third, and twenty-eight shelf mounting holes 13 from the top. For this reason, the number of the shelf mounting holes 13 formed in the region between the two adjacent region indicating marks (15A to 15F) is the same number (four).

  In the present embodiment, the number of through holes constituting the region indicating marks 15A to 15F is one, two, three, three, two, and one in order. For this reason, the 30 shelf mounting holes 13 and the 6 region indicating marks 15A to 15F are line-symmetric with respect to the virtual line I passing through the center of the rack frame 5A in the longitudinal direction and orthogonal to the longitudinal direction. It is formed to become. The six region indication marks 15A to 15F are formed so that the number of through holes decreases by one as the distance from the virtual line I that is the axis of symmetry increases. The four mounting through holes 11, 30 shelf plate mounting holes 13, six region indicating marks 15A to 15F, four mounting through holes 17 and 30 mounting plate mounting holes 19 are separately provided. You may form, and you may form simultaneously by press work.

  Next, a state where the four rack frames 5A to 5D are arranged will be described. As shown in FIGS. 1 and 2, the rack frames 5B and 5D adjacent to the rack frame 5A are arranged with the rack frame 5A upside down. The rack frame 5C located diagonally to the rack frame 5A is arranged in the same vertical direction as the rack frame 5A. Thereby, the rack frame 5A and the rack frame 5B are arranged so that the plate-like portions 5g in which the shelf mounting holes 13 are formed face each other, and the rack frame 5C and the rack frame 5D The plate-like portions 5g in which the attachment holes 13 are formed are arranged so as to face each other. The positions of the 30 shelf mounting holes 13 and the six area instruction marks 15A to 15F of the four rack frames 5A to 5D are the same. The operator who assembles the racks respectively enters the shelf mounting holes 13 that are separated by a predetermined number below or above the area indication marks (15A to 15F) of the same number of through holes of the four rack frames 5A to 5D. By attaching the shelf mounting fixture, the shelf mounting fixture can be easily and accurately attached. The area instruction marks 15A to 15F of the present embodiment are provided corresponding to the shelf mounting positions in standard use, but the area instruction marks can be formed at desired positions according to the use of the rack. Of course.

  According to the rack of the present embodiment, the two adjacent rack frames (5A, 5B), (5B, 5C), (5C, 5D) are arranged oppositely in the vertical direction. By arranging the two rack frames (5A, 5C) and (5B, 5D) in the same vertical direction, a rack can be formed only by preparing one type of vertical frame.

  In the above embodiment, the rack frame is used as a vertical frame. However, when the rack has a horizontally long structure, it is needless to say that the rack frame of the present invention may be used as a horizontal frame.

  According to the present invention, even if the rack frame is turned upside down (or left and right), the positions of the plurality of shelf mounting holes and the plurality of area indication marks are the same. Therefore, the rack frame can be used with its vertical direction (or left-right direction) reversed, and the types of rack frames used for assembling one rack can be reduced.
