Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, for example, when displaying articles on a storage shelf, there may be a case where one of a plurality of shelf boards is arranged vertically and the articles are suspended and displayed using a hanging tool on the vertically arranged shelf board. However, the conventional storage shelf is not configured to be able to arrange the shelf board vertically. For this reason, the applicable range of the storage shelf may not be appropriately ensured.

[0005] An object of the present invention is to provide a storage shelf capable of arbitrarily selecting the posture of arranging the shelf board from a horizontal position and a vertical position.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention proposes the following means. (1) The storage shelf according to the present invention includes a pair of column portions that are raised from positions spaced apart in the horizontal direction and are provided with connecting pins, a shelf board that is rotatably connected to the connecting pins and can be arranged at a horizontal position intersecting the column portions with the connecting pins as an axis and at a vertical position along the column portions, and a support portion that holds the shelf board at the horizontal position.

[0007] According to this configuration, connecting pins are provided on the pair of column portions, and the shelf board is rotatably connected to the connecting pins. The shelf board can be arranged at the horizontal position and the vertical position with the connecting pins as an axis. Thereby, the posture of arranging the shelf board can be arbitrarily selected from the horizontal position and the vertical position. By arbitrarily selecting the posture of the shelf board from the horizontal position and the vertical position, the applicable range of the storage shelf can be appropriately ensured.

[0008] (2) In the above aspect, the support portion may be rotatably supported by the shelf board and have a clearance portion with respect to the connecting pin so that it can be arranged along the column portion.

[0009] According to this configuration, a clearance portion with respect to the connecting pin is provided in the support portion. Therefore, in a state where the support portion is arranged along the column portion, the clearance portion can be escaped from the connecting pin. Thereby, in a state where the shelf board is arranged at the vertical position, the support portion can be arranged along the shelf board. Therefore, the design property of the storage shelf can be enhanced.

[0010] (3) In the above aspect, the support portion may be held by the shelf board with a predetermined frictional force in a state where it is arranged along the shelf board.

[0011] According to this configuration, the support portion can be held along the shelf board with a predetermined frictional force. Therefore, for example, it is possible to prevent the support portion from rotating about the connecting pin. Thereby, it is possible to prevent the support portion from interfering with the shelf board and generating interference noise.

[0012] (4) In the above aspect, the shelf board may be stretchable in the longitudinal direction.

[0013] According to this configuration, the shelf board can be expanded and contracted in the longitudinal direction. Therefore, the length of the shelf board can be changed according to the location and use of the storage shelf. As a result, the storage shelf can be appropriately adapted to the location and use.

[0014] (5) In the above aspect, the column portion may be expandable and contractible in the longitudinal direction.

[0015] According to this configuration, the column portion can be expanded and contracted in the longitudinal direction. Therefore, for example, the column portion can be expanded and contracted so that the upper end portion of the column portion abuts against the ceiling. As a result, the column portion can be held in a state of being stretched between the floor portion and the ceiling, similar to a tension rod. Therefore, the column portion can be stably held, and the shelf board can be firmly supported by the column portion. In addition, it can also be applied to ceiling portions with different heights. As a result, the range of applications can be expanded.

Advantages of the Invention

[0016] According to the present invention, the posture in which the shelf board is arranged can be arbitrarily selected from the horizontal position and the vertical position.

Best Mode for Carrying Out the Invention

[0018] Hereinafter, with reference to the drawings, a storage shelf according to an embodiment of the present invention will be described. Hereinafter, the upper side of the storage shelf will be described as the upper side, and the lower side of the storage shelf will be described as the lower side. Also, the front side of the storage shelf will be described as the front, and the back side of the storage shelf will be described as the back. Further, when viewing the storage shelf from the front side, the left side will be described as the left direction, and the right side when viewing the storage shelf from the front side will be described as the right direction.

[0019] <Storage Shelf> FIG. 1 is a perspective view of the storage shelf according to the embodiment with the shelf board provided thereon disposed in a horizontal position as viewed from the front. FIG. 2 is a perspective view of the storage shelf according to the embodiment with the shelf board provided thereon disposed in a vertical position as viewed from the front. As shown in FIGS. 1 and 2, the storage shelf 10 is used, for example, as a display shelf for storing and displaying products (articles) on the shelf board in a store or the like, or as a storage shelf for storing cooking utensils (articles) in a cooking room. The storage shelf 10 includes a pair of column portions 12, 13, a plurality of shelf boards 15, a plurality of first support portions (support portions) 17, and a plurality of second support portions (support portions) 18.

[0020] <Column Portion> The pair of column portions 12, 13 are erected, for example, at positions spaced apart in the left-right direction (horizontal direction). Hereinafter, among the pair of column portions 12, 13, one column portion 12 disposed on the left side will be described as the first column portion 12, and the other column portion 13 disposed on the right side will be described as the second column portion 13. The first column portion 12 and the second column portion 13 are configured symmetrically.

[0021] The first column portion 12 includes a support column 21, a lower contact portion 22, a column frame 23, and an upper contact portion (the upper end portion of the first column portion 12) 24. The support column 21 is formed with a hollow having a rectangular cross section. A lower contact portion 22 is inserted into the lower end portion 21a of the support column 21 so as to be slidable in the axial direction. The lower contact portion 22 is biased in a protruding direction with respect to the lower end portion 21a of the support column 21 by a compression spring (not shown). The compression spring (not shown) is housed in the lower end portion 21a of the support column 21.

[0022] Figure 3 is a perspective view seen from the rear of the shelf board provided in the storage shelf of the embodiment arranged in a horizontal position. As shown in FIG. 3, the lower end portion 23a of the column frame 23 is slidably fitted in the axial direction to the upper end portion 21b of the column 21. Therefore, the first column portion 12 is configured to be expandable and contractible with respect to the axial direction (that is, the longitudinal direction). The column frame 23 is formed in a hollow shape with a rectangular cross section. A welding nut 26 is provided on the rear wall 23b at the lower end portion 23a of the column frame 23. A fixing screw 27 is screwed to the welding nut 26. The fixing screw 27 screwed to the welding nut 26 penetrates through a through hole (not shown) in the rear wall 23b. Therefore, the tip of the fixing screw 27 abuts against the upper end portion 21b of the column 21. Thereby, the column frame 23 is fixed at a predetermined position in a state of being fitted to the upper end portion 21b of the column 21. An upper contact portion 24 is fixed to the upper end portion 23c of the column frame 23.

[0023] As shown in FIGS. 1 and 2, the first column portion 12 is expandable and contractible, for example, according to the distance between the floor portion FL and the ceiling portion CE by sliding the upper end portion 21b of the column 21 and the lower end portion 23a of the column frame 23 in the axial direction. Therefore, the first column portion 12 can be expanded and contracted so that the lower contact portion 22 abuts against the floor portion FL and the upper contact portion 24 abuts against the ceiling portion CE. In this state, a compression spring (not shown) housed in the lower end portion 21a of the column 21 is kept in a compressed state. Thereby, the first column portion 12 is held in a state of being stretched between the floor portion FL and the ceiling portion CE by the biasing force of the compression spring, similar to a tension bar.

[0024] Figure 4 is an enlarged perspective view of part IV of FIG. 3. As shown in FIGS. 3 and 4, a plurality of connecting pins 31 are provided on the inner wall 23d of the column frame 23. In the embodiment, six connecting pins 31 will be described as an example, but the number of connecting pins 31 can be arbitrarily selected. The plurality of connecting pins 31 are arranged at regular intervals L in the vertical direction. The plurality of connecting pins 31 protrude horizontally from the inner wall 23d, and an overhanging portion 32 is provided at the tip.

[0025] As shown in FIGS. 1 and 2, the second column portion 13 is configured symmetrically with respect to the left and right with respect to the first column portion 12. Therefore, the same reference numerals as those of the first column portion 12 are given to the constituent members of the second column portion 13, and detailed description thereof is omitted.

[0026] <Shelf board> As shown in FIGS. 1 to 3, a plurality of shelf boards 15 are connected between the first column portion 12 and the second column portion 13. In the embodiment, two shelf boards 15 are taken as an example for explanation of the plurality of shelf boards 15. Note that the number of the shelf boards 15 is not limited to two. The shelf board 15 has a plurality of groove portions 34 and 35 at the left end portion and the right end portion. The groove portions 34 and 35 are rotatably connected to the connecting pin 31. By rotating the groove portions 34 and 35 about the connecting pin 31, the shelf board 15 is arranged at the horizontal position P1 and the vertical position P2 (see also FIG. 7). Hereinafter, the horizontal position P1 may be referred to as "first position P1", and the vertical position P2 may be referred to as "second position P2". In the embodiment, for ease of understanding of the configuration, based on the state where the shelf board 15 is arranged at the first position P1, the front side is described as the front of the shelf board 15, and the rear side is described as the rear of the shelf board 15.

[0027] As shown in FIGS. 3 and 4, the shelf board 15 includes a first shelf board 41 and a second shelf board 42. The first shelf board 41 is formed of a steel plate (iron plate) in the left half of the shelf board 15.

The first stopper 52 is formed of, for example, a rod. The first stopper 52 has a pair of protruding portions 53 protruding to the opposite side of the first shelf plate body 44.

[0030] As shown in FIG. 4, the first side wall 47 is bent from the left side of the first shelf plate body 44 toward the back side so as to be orthogonal to the first shelf plate body 44. The first side wall 47 has a plurality of groove portions 34. In the embodiment, three groove portions 34 will be described as an example of the plurality of groove portions 34. Hereinafter, the three groove portions 34 will be described as a "first groove portion 34A", a "second groove portion 34B", and a "third groove portion 34C". Note that the number of the groove portions 34 is not limited to three.

[0031] The first groove portion 34A is provided at the rear end portion of the first side wall 47. The first groove portion 34A has an opening 34Aa. The opening 34Aa is opened on the side of the first side wall 47 opposite to the opposite side of the first shelf plate body 44. The first groove portion 34A extends from the opening 34Aa toward the first shelf plate body 44 and extends rearward from the position on the first shelf plate body 44 side, thereby being formed in an L shape. The first groove portion 34A has a groove bottom 34Ab. The first groove portion 34A is fitted into the connecting pin 31 from the opening 34Aa, and the groove bottom 34Ab contacts the connecting pin 31.

The first groove portion 34A, the second groove portion 34B, and the third groove portion 34C are arranged at regular intervals L in the vertical direction, similar to the plurality of connecting pins 31. A first support portion 17 is connected to the first side wall 47. The first support portion 17 is provided between the first groove portion 34A and the third groove portion 34C. The first support portion 17 will be described in detail later.

[0033] FIG. 6 is a perspective view of the second shelf board of the embodiment in a state where it is arranged in a horizontal position, viewed from the rear. As shown in FIGS. 3 and 6, the second shelf board 42 is formed substantially symmetrically with respect to the left and right with respect to the first shelf board 41. The second shelf board 42 is formed such that the fitting end portion 42a can be fitted into the insertion end portion 41a of the first shelf board 41. Specifically, the second shelf board 42 has a second shelf board main body 54, a second front wall 55, a second rear wall 56, and second side walls 57.

[0034] The second shelf board main body 54 is formed in a flat plate shape having a rectangular shape in plan view. Hereinafter, in the second shelf board main body 54, the upper side will be described as the front surface and the lower side as the back surface based on the state where the shelf board 15 is horizontally arranged. The second front wall 55 is bent from the front side of the second shelf board main body 54 toward the back surface side so as to be orthogonal to the second shelf board main body 54. The second rear wall 56 is bent from the rear side of the second shelf board main body 54 toward the back surface side so as to be orthogonal to the second shelf board main body 54. The second shelf board main body 54, the second front wall 55, and the second rear wall 56 are formed in a U-shaped cross section.

[0035] As shown in FIGS. 3 and 5, a second front flange 58 is bent from a side of the second front wall 55 opposite to the second shelf plate body 54. A second rear flange 59 is bent from a side of the second rear wall 56 opposite to the second shelf plate body 54. A second stopper 62 is provided over the outer surfaces of the second front flange 58 and the second rear flange 59 at a fitting end portion 42a of the second shelf plate 42 on the side opposite to the second side wall 57. The second stopper 62 is disposed so as to be capable of contacting a pair of protrusions 53 on the first stopper 52.

[0036] As shown in FIGS. 3 and 6, the second side wall 57 is bent from the right side of the second shelf plate body 54 toward the back side so as to be orthogonal to the second shelf plate body 54. Similar to the first side wall 47, the second side wall 57 has a plurality of groove portions 35. In the embodiment, three groove portions 35 will be described as an example of the plurality of groove portions 35. Hereinafter, the three groove portions 35 will be described as a "first groove portion 35A", a "second groove portion 35B", and a "third groove portion 35C". Note that the number of the groove portions 35 is not limited to three. The first groove portion 35A to the third groove portion 35C of the second side wall 57 are formed in the same manner as the first groove portion 34A to the third groove portion 34C of the first side wall 47.

[0037] The first groove portion 35A is provided at the rear end portion of the second side wall 57. The first groove portion 35A has an opening 35Aa. The opening 35Aa is opened at a side of the second side wall 57 opposite to the second shelf plate body 54. The first groove portion 35A extends from the opening 35Aa toward the second shelf plate body 54 and extends rearward from a position on the second shelf plate body 54 side, thereby being formed in an L shape. The first groove portion 35A has a groove bottom portion 35Ab. The first groove portion 35A is fitted into the connecting pin 31 from the opening 35Aa, and the groove bottom portion 35Ab contacts the connecting pin 31. In this state, the first groove portion 35A is rotatably connected to the connecting pin 31.

[0038] The second groove portion 35B is provided at the front end portion of the second side wall 57. The second groove portion 35B is formed in the same manner as the first groove portion 35A. The second groove portion 35B has an opening portion 35Ba and a groove bottom portion 35Bb. The third groove portion 35C is provided between the first groove portion 35A and the second groove portion 35B. The third groove portion 35C has an opening portion 35Ca and a groove bottom portion 35Cb. The first groove portion 35A, the second groove portion 35B, and the third groove portion 35C are arranged at regular intervals L in the vertical direction, similar to the plurality of connecting pins 31. A second support portion 18 is connected to the second side wall 57. The second support portion 18 is provided between the first groove portion 35A and the third groove portion 35C. The second support portion 18 will be described in detail later.

[0039] As shown in FIGS. 3 and 5, the fitting end portion 42a of the second shelf board 42 is fitted into the insertion end portion 41a of the first shelf board 41 in the longitudinal direction of the shelf board 15. In this state, the first shelf board 41 and the second shelf board 42 are integrally connected so as to be slidable in the longitudinal direction (left - right direction). The shelf board 15 is constituted by the first shelf board 41 and the second shelf board 42. That is, the shelf board 15 is configured to be expandable and contractible in the longitudinal direction by sliding the first shelf board 41 and the second shelf board 42 in the longitudinal direction.

[0040] Also, by fitting the fitting end portion 42a of the second shelf board 42 into the insertion end portion 41a of the first shelf board 41, the fitting end portion 42a and the insertion end portion 41a can be connected. Therefore, the connecting portion between the fitting end portion 42a and the insertion end portion 41a can be made into a double - structure. Thereby, the rigidity (strength) at the connecting portion between the fitting end portion 42a and the insertion end portion 41a can be ensured with a simple configuration. Therefore, relatively heavy articles can be stored on the shelf board 15.

[0041] Here, a first stopper 52 is provided at the insertion end portion 41a of the first shelf board 41, and the first stopper 52 has a pair of protruding portions 53. Further, a second stopper 62 is provided at the fitting end portion 42a of the second shelf board 42, and the second stopper 62 is made capable of contacting the pair of protruding portions 53. Therefore, when the first shelf board 41 and the second shelf board 42 are slid to extend the shelf board 15 to the maximum position in the longitudinal direction, the pair of protruding portions 53 and the second stopper 62 come into contact. Thereby, it is possible to prevent the insertion end portion 41a of the first shelf board 41 from coming out of the fitting end portion 42a of the second shelf board 42.

[0042] As shown in FIGS. 3, 4, and 6, for the shelf board 15, the first groove portion 34A of the first side wall 47 is fitted into the connecting pin 31 of the first column portion 12, and the first groove portion 35A of the second side wall 57 is fitted into the connecting pin 31 of the second column portion 13. The groove bottom portion 34Ab of the first groove portion 34A of the first side wall 47 contacts the connecting pin 31. The groove bottom portion 35Ab of the first groove portion 35A of the second side wall 57 contacts the connecting pin 31. In this state, the shelf board 15 is rotatably connected to the connecting pin 31 of the first column portion 12 and the connecting pin 31 of the second column portion 13. The shelf board 15 can be arranged at a first position P1 that intersects (orthogonal in the embodiment) the first column portion 12 and the second column portion 13 about the connecting pin 31 of the first column portion 12 and the connecting pin 31 of the second column portion 13. Further, the shelf board 15 can be arranged at a second position P2 (see FIG. 2) along the first column portion 12 and the second column portion 13 about the connecting pin 31 of the first column portion 12 and the connecting pin 31 of the second column portion 13.

[0043] <First support portion> As shown in FIGS. 3 and 4, the first support portion 17 is formed of, for example, a strip-shaped steel plate (iron plate). The first support portion 17 has a first end portion 71, a second end portion 72, and a relief portion 73. The first end portion 71 is rotatably attached, for example, between the first groove portion 34A and the third groove portion 34C in the first side wall 47 with a rivet 75. That is, the first support portion 17 is rotatably supported by the first side wall 47 via the rivet 75. The second end portion 72 has a locking groove 76. The locking groove 76 is open at the end edge of the second end portion 72 and extends toward the relief portion 73. The locking groove 76 is locked to the lowermost adjacent connecting pin 31 with respect to the connecting pin 31 to which the first groove portion 34A is connected in a state where the shelf board 15 is disposed at the first position P1.

[0044] The relief portion 73 is bent so as to bulge toward the side opposite to the first column portion 12 (that is, the right side). Specifically, the relief portion 73 has, for example, a pair of bent pieces 73a and a connecting side 73b. The pair of bent pieces 73a are bent from the first end portion 71 and the second end portion 72 toward the side opposite to the first column portion 12, respectively. The connecting side 73b connects the ends of the pair of bent pieces 73a. That is, the relief portion 73 is a bent portion formed in a boat bottom shape (trapezoidal shape) by the pair of bent pieces 73a and the connecting side 73b. In the embodiment, a trapezoidal bent portion is described as an example of the relief portion 73, but the relief portion 73 is not limited to a bent portion. As another example, for example, the relief portion 73 may have other shapes such as a curved portion or an opening portion.

[0045] FIG. 7 is a perspective view of the first shelf board of the embodiment disposed in a vertical position as viewed from the rear. As shown in FIG. 7, the first support portion 17 is disposed along the first side wall 47 in a state where the shelf board 15 is disposed at the second position P2. In this state, the relief portion 73 is disposed at a position corresponding to the lowermost adjacent connecting pin 31 with respect to the connecting pin 31 to which the first groove portion 34A is connected. The relief portion 73 is disposed at a position away from the lowermost adjacent connecting pin 31 in a state where the shelf board 15 is disposed at the second position P2. Therefore, the first support portion 17 is disposed along the first side wall 47 and the first column portion 12 without interfering with the lowermost adjacent connecting pin 31 in a state where the shelf board 15 is disposed at the second position P2.

[0046] In addition, when the first support portion 17 is arranged along the first side wall 47, a predetermined frictional force is generated. The predetermined frictional force is generated, for example, between the first end portion 71 of the first support portion 17 and the first support portion 17 when the first end portion 71 contacts the first side wall 47. The predetermined frictional force can prevent the first support portion 17 from rotating under its own weight about the rivet 75, for example. Therefore, the first support portion 17 is held by the predetermined frictional force in a state of being arranged along the first side wall 47.

[0047] <Second support portion> As shown in FIGS. 3, 4, and 6, the second support portion 18 is formed symmetrically with respect to the first support portion 17. Therefore, the same reference numerals as those of the first support portion 17 are given to the respective components of the second support portion 18, and detailed description thereof is omitted. When the shelf board 15 is arranged at the first position P1, the locking groove 76 of the second support portion 18 is locked to the lowermost adjacent connecting pin 31 with respect to the connecting pin 31 to which the first groove portion 35A is connected. Also, when the shelf board 15 is arranged at the first position P1, the locking groove 76 of the first support portion 17 is locked to the lowermost adjacent connecting pin 31 with respect to the connecting pin 31 to which the first groove portion 34A is connected. Thereby, the shelf board 15 is held at the first position P1 by the first support portion 17 and the second support portion 18.

[0048] As shown in FIGS. 6 and 7, the second support portion 18 is arranged along the second side wall 57 and the second column portion 13 without interfering with the lowermost adjacent connecting pin 31 when the shelf board 15 is arranged at the second position P2, similar to the first support portion 17. Also, when the second support portion 18 is arranged along the second side wall 57, a predetermined frictional force is generated, similar to the first support portion 17. The predetermined frictional force can prevent the second support portion 18 from rotating under its own weight about the rivet 75, for example. Therefore, the second support portion 18 is held in a state of being arranged along the second side wall 57.

[0049] As described above, according to the storage shelf 10 of the embodiment, as shown in FIGS. 1 to 3, a connecting pin 31 is provided on the first column portion 12, and a connecting pin 31 is provided on the second column portion 13. The shelf board 15 is rotatably connected to the connecting pin 31 of the first column portion 12 and the connecting pin 31 of the second column portion 13. Further, the shelf board 15 can be arranged around the connecting pin 31 at the first position P1 and the second position P2. Thereby, the posture of arranging the shelf board 15 can be arbitrarily selected from the first position P1 and the second position P2. By arbitrarily selecting the posture of the shelf board 15 from the first position P1 and the second position P2, the applicable range of the storage shelf 10 can be appropriately ensured.

[0050] For example, according to the storage shelf 10, it is possible to arrange both of the two shelf boards 15 at the first position P1. Also, it is possible to arrange one of the two shelf boards 15 at the first position P1 and the other at the second position P2. Further, it is possible to arrange both of the two shelf boards 15 at the second position P2. Here, the shelf board 15 is formed of a steel plate. Therefore, in a state where the shelf board 15 is arranged at the second position P2, for example, it is also possible to fix a lifting tool (not shown) to the shelf board 15 with a magnet and suspend an article from the lifting tool. Thereby, the applicable range of the storage shelf 10 can be expanded.

[0051] Also, as shown in FIGS. 4 and 6, a clearance portion 73 for the connecting pin 31 is provided on the first support portion 17. Therefore, in a state where the first support portion 17 is arranged along the first column portion 12, the clearance portion 73 can be released from the connecting pin 31. Also, a clearance portion 73 for the connecting pin 31 is provided on the second support portion 18. Therefore, in a state where the second support portion 18 is arranged along the second column portion 13, the clearance portion 73 can be released from the connecting pin 31. Thereby, in a state where the shelf board 15 is arranged at the second position P2 (see FIG. 2), the first support portion 17 can be arranged along the first side wall 47 of the shelf board 15, and the second support portion 18 can be arranged along the second side wall 57 of the shelf board 15. Therefore, the design property of the storage shelf 10 can be enhanced.

[0052] Furthermore, as shown in FIGS. 6 and 7, the first support portion 17 can be held along the first side wall 47 of the shelf board 15 by a predetermined frictional force. Also, the second support portion 18 can be held along the second side wall 57 of the shelf board 15 by a predetermined frictional force. Thus, for example, it is possible to prevent the first support portion 17 and the second support portion 18 from rotating about the connecting pin 31. Thereby, for example, it is possible to prevent the first support portion 17 and the second support portion 18 from interfering with the shelf board 15 and generating interference noise.

[0053] In addition, as shown in FIGS. 3 and 5, the shelf board 15 is made stretchable in the longitudinal direction. Thus, the length of the shelf board 15 can be changed according to the place of use and application of the storage shelf 10. Thereby, the storage shelf 10 can be appropriately adapted to the place of use and application.

[0054] Furthermore, as shown in FIGS. 1 and 2, the first column portion 12 and the second column portion 13 are made stretchable in the longitudinal direction. Thus, for example, the first column portion 12 can be extended and contracted so that the upper contact portion 24 of the first column portion 12 abuts against the ceiling portion CE. Also, the second column portion 13 can be extended and contracted so that the upper contact portion 24 of the second column portion 13 abuts against the ceiling portion CE. Thereby, the first column portion 12 and the second column portion 13 can be held in a state of being stretched between the floor portion FL and the ceiling portion CE, similarly to a tension rod. Therefore, the first column portion 12 and the second column portion 13 can be stably held, and the shelf board 15 can be firmly supported by the first column portion 12 and the second column portion 13.

[0055] Note that the technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. In the above embodiment, an example in which the first shelf board 41 and the second shelf board 42 of the shelf board 15 are formed of a steel plate has been described, but the present invention is not limited thereto. As another example, the first shelf board 41 and the second shelf board 42 may be formed of other materials such as resin. Also, an example in which the first support portion 17 and the second support portion 18 are formed of a steel plate has been described, but the present invention is not limited thereto. As another example, the first support portion 17 and the second support portion 18 may be formed of other materials such as resin.

[0056] In addition, within the scope not departing from the gist of the present invention, it is possible to appropriately replace the constituent elements in the above-described embodiment with well-known constituent elements, and the above-described modified examples may also be appropriately combined.
