[Figure 4] FIG. 13 is a diagram showing a state in which an article is placed on the upper surface of the rack. [Diagram 5] FIG. 13 is a diagram showing a state in which an article is placed on the upper surface of the rack. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] <Embodiment 1> A first embodiment of the present disclosure will be described with reference to Fig. 1 to Fig. 5. Fig. 1 to Fig. 3 show the configuration of a rack. Fig. 4 to Fig. 5 are diagrams showing a state in which an article is placed on the upper surface of the rack.

[0014] The rack 1 in this embodiment is formed in a substantially rectangular parallelepiped or cubic shape, as shown in Fig. 1. Specifically, the rack 1 includes four support members 11, 12, 13, and 14 that are erected vertically at the four corners of a substantially square shape, three beam members 22, 23, and 24 (lower beam members) that connect the lower ends of the support members 11, 12, 13, and 14 in the horizontal direction, and four beam members 31, 32, 33, and 34 (upper beam members) that connect the upper ends of the support members 11, 12, 13, and 14 in the horizontal direction.

[0015] 3, the upper surface of the rack 1 forms a substantially square or rectangular mounting surface surrounded by the above-mentioned four upper end beam members 31, 32, 33, and 34. This mounting surface will be described later.

[0016] In addition, no beam member is provided between the lower ends of the support members 11 and 12, and it is possible to store luggage in the rack 1 from the support members 11 and 12 side. That is, in this embodiment, the support members 11 and 12 form the front side of the rack, and the support members 13 and 14 form the rear side of the rack. In this embodiment, the direction between the support members 11 and 14 and between the support members 12 and 13 and along the longitudinal direction of the beam members 32 and 34 forming the upper surface part is defined as the front-rear direction of the rack. And the direction perpendicular to the front-rear direction of the rack, that is, the direction between the support members 11 and 12 and between the support members 13 and 14 and along the longitudinal direction of the beam members 31 and 33 forming the upper surface part is defined as the width direction of the rack.

[0017] Moreover, the same racks 1 can be stacked. Specifically, Fig. 2 shows the state when the racks are stacked. Note that although the upper rack 100 and the lower rack 1 are the same, for convenience of explanation, the upper rack 100 will be indicated by a different reference symbol.

[0018] As shown in this figure, when stacking the racks 1,100, first, on the front side, the lower ends of the front support members 111, 112 of the upper rack 100 are stacked on the upper ends of the front support members 11, 12 of the lower rack 1. At this time, the semispherical convex parts provided at the lower ends of the upper support members 111, 112 fit into the semispherical concave parts provided at the upper ends of the lower support members 11, 12. Also, on the rear side, the beam member 123 located at the lower end of the upper rack 100 is placed on the beam member 33 located on the upper surface of the lower rack 1. At this time, as shown in FIG. 1, stoppers 61, 62 protruding above the placement surface are provided near both ends of the beam member 33 located on the rear side of the upper surface (placement surface) of the rack 1. Since these stoppers 61, 62 are provided outside the outer periphery of the top surface (support surface) of rack 1, by placing the beam member 123 of the upper rack 100 further inward, it is possible to prevent the front and rear racks from shifting out of position and to stabilize the stacked state.

[0019] In this manner, by stacking the racks 1,100, items can be stored inside the lower rack 1 and on the mounting surface which is the upper surface of the lower rack 1, i.e., inside the upper rack 100 and on the mounting surface which is the upper surface of the upper rack 100.

[0020] Here, the configuration of the placement surface, which is the upper surface of the rack 1 on which an article is placed, will be described in detail. As shown in Fig. 1 and Fig. 3, which is a top view of Fig. 1, the placement surface, which is the upper surface of the rack 1, has an outer periphery formed by four upper beam members 31, 32, 33, and 34 that respectively connect the upper ends of the four support members 11, 12, 13, and 14. At this time, the four upper beam members 31, 32, 33, and 34 are formed to be approximately the same length and are connected to each other at right angles, so that the placement surface is formed in an approximately square or approximately rectangular shape.

[0021] Inside the outer periphery of the mounting surface surrounded by the four upper beam members 31, 32, 33, 34, a lattice-shaped lattice member formed of beam members 41, 42, 43, 44 connecting the upper beam members facing each other is provided. Specifically, the lattice member is formed by intersecting and connecting two beam members 41, 42 that connect the upper beam members 32, 34 facing each other on both sides of the rack 1 and extend in the width direction of the rack 1, and two beam members 43, 44 that connect the upper beam members 31, 33 facing each other on the front side and rear side of the rack 1 and extend in the front-rear direction of the rack 1. The two beam members 43, 44 that connect the front side and rear side of the rack 1 are cut at the intersection with the two beam members 41, 42 that connect the both sides, and are butt-joined. As a result, the upper surface of the lattice member is formed flat, and together with the upper end beam members 31, 32, 33, and 34 that form the outer periphery, a flat support surface is formed.

[0022] The number of beam members forming the above-mentioned lattice member is not limited to the above-mentioned number. For example, the number of beam members 43, 44 extending along the front-rear direction of the rack is not limited to two, and may be three or more. The number of beam members 41, 42 extending along the width direction of the rack is not limited to two, and may be three or more.

[0023] Furthermore, support members 51, 52, 53, and 54 (connecting members) that form the mounting surface are provided at the four corners, i.e., the four corners, of the mounting surface that is the upper surface of the rack 1. Specifically, the support member 51 is a linear member, here a plate-like member having a width substantially equal to that of the upper beam member 31, which is a square timber, and is provided to connect the adjacent upper beam members 31 and 32 that are connected at a right angle. At this time, the plate-like support member 51 is arranged so that one side end along the longitudinal direction faces the upper side of the rack 1 and is positioned at the same height as the upper surfaces of the lattice members and the upper beam members 31, 32, 33, and 34.

[0024] Similarly to the support member 51, the other support members 52, 53, 54 are provided to connect the adjacent upper beam members connected at right angles. Specifically, the support member 52 connects the upper beam members 32, 33, the support member 53 connects the upper beam members 33, 34, and the support member 54 connects the upper beam members 34, 31. As a result, the four corners of the placement surface, which is the upper surface of the rack 1, are each formed into a triangular shape by the upper beam members 31, 32, 33, 34 and the support members 51, 52, 53, 54 when viewed from above.

[0025] The upper parts of the upper beam members 31, 32, 33, 34, the lattice members 41, 42, 43, 44, and the support members 51, 52, 53, 54 form a flat mounting surface. As a result, the article 200 can be placed on the mounting surface as shown by the imaginary lines in Figs. 4 and 5. At this time, since the support members 51, 52, 53, 54 are located near the four corners of the mounting surface, the corners of the rectangular parallelepiped or cubic article 200 can be supported, and the article itself can be stably supported. In addition, by forming the inside of the mounting surface into a lattice shape with a total of four or more beam members, two vertically and two horizontally, the gaps in the mounting surface are small, and the article 200 can be supported more stably.

[0026] Furthermore, by connecting support members 51, 52, 53, and 54 near the corners of the mounting surface as described above, the strength of the mounting surface, which is the upper surface of rack 1, can be increased even if the number of beam members that make up lattice members 41, 42, 43, and 44 is small.

[0027] In the above, the support members 51, 52, 53, and 54 are provided at all four corners of the mounting surface, which is the upper surface of the rack 1, but the support members do not necessarily have to be provided at all corners, and may be provided at only some of the corners. In addition, the lattice members provided on the mounting surface are not limited to the above-mentioned shapes, and may be of any shape and may be composed of any number of beam members.

[0028] Also, the shape of the mounting surface, which is the upper surface of the rack 1, has been described as being approximately square or rectangular, but it may be any shape. In other words, the upper end beam members forming the periphery of the mounting surface may be connected to adjacent ones at any angle, as long as a linear support member is connected between them.

[0029] The beam members and other members that make up rack 1 are mainly connected (joined) by welding, but they may be connected in any manner, such as by adhesion or using fasteners such as bolts.

[0030] Although the present disclosure has been described with reference to the above-mentioned embodiments, the present disclosure is not limited to the above-mentioned embodiments. Various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure.
