[0009] <First Embodiment> A first embodiment of this disclosure will be described with reference to the drawings. The drawings may be relevant to any embodiment.
[0010] First, Figure 1 shows the overall configuration of rack 1 in this embodiment. As shown in Figure 1, rack 1 in this embodiment is formed in a substantially rectangular parallelepiped or substantially cubic shape. Specifically, rack 1 comprises four support members 11, 12, 13, and 14 erected vertically at each of the four corners of a substantially square shape, three beam members 22, 23, and 24 (lower beam members) that connect the lower ends of these 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.
[0011] Furthermore, no beam member is provided between the lower ends of the support members 11 and 12 as described above, making it possible to store luggage in the rack 1 from the side of the support members 11 and 12. In other words, in this embodiment, the space between support members 11 and 12 forms the front of the rack, and the space between support members 13 and 14 forms the back of the rack. In this embodiment, the direction along the longitudinal direction of the beam members 32 and 34, which are aligned with the space between support members 11 and 14 and the space between support members 12 and 13 and form the upper surface described later, is defined as the front-to-back direction of the rack. The direction perpendicular to the front-to-back direction of the rack, that is, the direction along the longitudinal direction of the beam members 31 and 33, which are aligned with the space between support members 11 and 12 and the space between support members 13 and 14 and form the upper surface, is defined as the width direction of the rack.
[0012] As shown in Figure 1, the upper surface of rack 1 forms a roughly square or rectangular mounting surface enclosed by the four upper beam members 31, 32, 33, and 34 described above. Specifically, the mounting surface is formed horizontally by the four upper beam members 31, 32, 33, and 34 that connect the upper ends of the four support members 11, 12, 13, and 14, respectively. 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 the mounting surface is formed to be roughly square or rectangular. Although the upper beam members 31 to 34 are formed from timbers with a roughly square cross-section, beam members of any cross-sectional shape may be used.
[0013] Furthermore, within the outer perimeter of the mounting surface enclosed by the four upper beam members 31, 32, 33, and 34, a grid-like lattice member is provided, formed by beam members 41, 42, and 43 that connect the opposing upper beam members. Specifically, the lattice member is formed by the intersection and connection of two beam members 41 and 42 that are located on both sides of the rack 1 and connect the opposing upper beam members 32 and 34, extending in the width direction of the rack 1, and one beam member 43 that is located on the front and rear sides of the rack 1 and connect the opposing upper beam members 31 and 33, extending in the front-rear direction of the rack 1. Note that the beam member 43 connecting the front and rear sides of the rack 1 is cut at the point where it intersects with the two beam members 41 and 42 that connect the two sides and is butted together. As a result, the upper surface of the lattice member is formed as a flat horizontal surface, and together with the upper end beam members 31, 32, 33, and 34 that form the outer perimeter, it forms a flat mounting surface.
[0014] The number of beam members forming the lattice members described above is not limited to the number described above. For example, the beam member 43 extending along the front-to-back direction of the rack is not limited to one, but may be two, as shown by reference numerals 43 and 44 in Figure 2. In this case, the two beam members 43 and 44 connecting the front and rear sides of the rack 1 are cut at the point where they intersect with the two beam members 41 and 42 connecting the two sides, and are butted together. Furthermore, the beam members extending along the front-to-back direction of the rack are not limited to one or two, but may be three or more. Also, the beam members 41 and 42 extending along the width direction of the rack are not limited to two, but may be three or more.
[0015] Furthermore, rack attachments 50 are mounted at each of the four corners located at the outer periphery of the mounting surface, which is the upper surface of rack 1. Specifically, each corner of the mounting surface of rack 1 is formed by two of the upper beam members 31 to 34 being connected to each other at a right angle, and rack attachments 50 are mounted at each corner. For example, two upper beam members 31 and 32 are connected to each other at a right angle to form a corner, and rack attachments 50 are mounted at this corner. In this case, the rack attachments 50 mounted at each corner have the same configuration. Here, the configuration of a rack attachment 50 mounted at the corner formed between one upper beam member 31 and the other upper beam member 32 will be explained with reference to Figures 3 to 5, using this as an example. Figure 3 shows a top view (Figure 3(3-1)) and a bottom view (Figure 3(3-2)) of the rack attachment 50, Figure 4 shows a top front side perspective view (Figure 4(4-1)) and a rear side perspective view (Figure 4(4-2)), and Figure 5 shows a bottom front side perspective view (Figure 5(5-1)) and a rear side perspective view (Figure 5(5-2)).
[0016] The attachment 50 for the rack is configured to include a pair of first mounting parts 51 and second mounting parts 52, and a connecting member 53 that connects between the pair of mounting parts 51 and 52. Here, the first mounting part 51 is mounted on one upper end beam member 31, and the second mounting part 52 is to be mounted on the other upper end beam member 32. And the first mounting part 51 and the second mounting part 52 are formed in a substantially U shape with the lower side open so as to cover the upper surface side and both side surface sides at the mounting positions of the upper end beam members 31 and 32. Specifically, as shown in FIGS. 4 and 5, the first mounting part 51 includes a plate-like upper surface part 51a formed along the horizontal direction, and plate-like side surface parts 51b and 51c respectively connected to both sides of the upper surface part 51a and formed along the vertical direction. In other words, the first mounting part 51 is configured such that both end sides in the longitudinal direction of a plate-like member having a predetermined length are each bent at a right angle, the central portion forms the upper surface part 51a, and the bent both end portions respectively form the side surface parts 51b and 51c. At this time, since the upper end beam member 31 to be mounted is a square bar, the first mounting part 51 is formed in a substantially U shape with the lower side open, and an internal cavity part surrounded in three directions by the upper surface part 51a and the side surface parts 51b and 51c is formed. Thereby, the first mounting part 51 can be mounted on the upper end beam member 31 from above by inserting the mounting position of the upper end beam member 31 into the internal cavity part. And the first mounting part 51 is arranged so as to cover the upper surface side at the mounting position of the upper end beam member 31 with the upper surface part 51a and cover both side surface sides with the side surface parts 51b and 51c respectively. Note that the length between the connection positions of the upper surface part 51a and the side surface parts 51b and 51b, and the length from the connection position of the side surface parts 51b and 51c to the end part with the upper surface part 51a are formed to be substantially the same as the width of the upper end beam member 31 which is a square bar, but they may be formed in any length.
[0017] Furthermore, the second mounting portion 52 is configured in the same way as the first mounting portion 51 described above. That is, as shown in Figures 4 and 5, the second mounting portion 52 comprises a plate-shaped upper surface portion 52a formed along the horizontal direction, and plate-shaped side portions 52b and 52c connected to both sides of the upper surface portion 52a and formed along the vertical direction. In other words, the second mounting portion 52 is constructed by bending both ends of a plate-shaped member having a predetermined length at right angles in the longitudinal direction, with the central portion forming the upper surface portion 52a and the bent ends forming the side portions 52b and 52c, respectively. In this case, since the upper beam member 32 to be mounted is a square timber, the second mounting portion 52 is formed in a roughly U-shape with the lower side open, and an internal cavity is formed surrounded on three sides by the upper surface portion 52a and the side portions 52b and 52c. As a result, the second mounting portion 52 can be attached to the upper beam member 32 from above by inserting the mounting location of the upper beam member 32 into the internal cavity. The second mounting portion 52 is positioned so that the upper surface of the mounting location of the upper beam member 32 is covered by the upper portion 52a, and both side surfaces are covered by the side portions 52b and 52c, respectively. The length between the connection points of the upper portion 52a and the side portions 52b, 52b, and the length from the connection point of the side portions 52b, 52c to the end of the upper portion 52a are formed to be approximately the same as the width of the upper beam member 32, which is a square timber, but they may be formed to any length.
[0018] In addition, the connecting member 53 that constitutes the attachment 50 for the rack is formed to have a predetermined length and connects the side surfaces 51c and 52c of the paired first mounting portion 51 and second mounting portion 52. Specifically, as shown in FIG. 1, both ends in the longitudinal direction of the connecting member 53 are respectively joined to the side surface 51c of the first mounting portion 51 and the side surface 52c of the second mounting portion 52 located inside the corner formed between the upper end beam members 31 and 32 by welding or the like. In particular, the longitudinal direction of the connecting member 53 is connected at an angle of 45 degrees with respect to the plane formed by the side surfaces 51c and 52c of the first mounting portion 51 and the second mounting portion 52. Regarding this configuration in more detail, first, the inner surface sides of the side surfaces 51c and 52c of the first mounting portion 51 and the second mounting portion 52 located inside the corner are contact surfaces that contact the outer surfaces at the mounting locations of the upper end beam members 31 and 32, and the contact surfaces are formed along the longitudinal direction of the upper end beam members 31 and 32. Then, the connecting member 53 is arranged such that the longitudinal direction of the connecting member 53 forms an angle of 45 degrees with respect to the surface formed by the side surfaces 51c and 52c of the first mounting portion 51 and the second mounting portion 52, that is, the contact surface with the upper end beam members 31 and 32, and is connected to the outer surfaces of the side surfaces 51c and 52c. As a result, as shown in FIG. 1, when the attachment 50 for the rack is mounted on the rack 1, the connecting member 53 is arranged at an angle of 45 degrees with respect to the longitudinal direction of the upper end beam members 31 and 32 that form the corner. However, the connecting member 53 is not necessarily limited to being arranged at an angle of 45 degrees with respect to the longitudinal direction of the upper end beam members 31 and 32, and may be connected within the range of 40 degrees to 50 degrees, as long as it is connected at an acute angle.
[0019] The connecting member 53 is formed from a plate-shaped member having a predetermined width, and when the rack attachment 50 is mounted on the rack 1, the width direction of the plate-shaped member is positioned in the height direction of the rack 1, i.e., vertical direction. For example, the width of the plate-shaped connecting member 53 is formed to be equivalent to the height of the mounting parts 51 and 52 described above, i.e., the length from the connection point with the upper surfaces 51a and 52a of the side parts 51c and 52c to the end extending downwards. When the rack attachment 50 is mounted on the rack 1, the plate-shaped connecting member 53 is positioned so that one side end in the width direction, i.e., along the longitudinal direction, faces the upper side of the rack 1, and that side end is at the same height as the upper surfaces of the grid members and upper beam members 31 and 32. However, the width of the plate-shaped connecting member 53 may be formed to any length.
[0020] Furthermore, the length of the connecting member 53 is formed to be, for example, less than or equal to half the length of the upper beam members 31 and 32. By forming it to such a length, even if a grid member is formed on the mounting surface of the rack 1, as shown in Figures 1 and 2, it becomes possible to attach the rack attachment 50 to each corner. Specifically, when the connecting member 53 is configured at a 45-degree angle with respect to the longitudinal direction of the upper beam members 31 and 32, even if the grid member is composed of two beam members vertically and two horizontally, as shown in Figure 2, the mounting portion of the rack attachment 50 can be attached to the end side of the upper beam members 31 and 32 rather than the connection point between the grid member and the upper beam members 31 and 32, making it possible to place a rack attachment 50 at each of the four corners. However, the longitudinal length of the connecting member 53 may be formed to any length.
[0021] As shown in Figures 1 and 2, the rack attachment 50 described above can be attached to each corner forming between adjacent upper beam members that are connected at a right angle. At this time, the rack attachment 50 can be attached by inserting the upper beam members 31 and 32 into the openings of the first mounting portion 51 and the second mounting portion 52, and can be removed by pulling the upper beam members 31 and 32 out from the openings of the first mounting portion 51 and the second mounting portion 52. In this way, the rack attachment 50 can be attached to and detached from the upper beam members 31 and 32 from above by using the first mounting portion 51 and the second mounting portion 52.
[0022] In this way, by attaching rack attachments 50 to the four corners of the mounting surface, which is the upper surface of rack 1, each corner is formed into a triangular shape by the upper beam members 31-34 and the connecting members 53 of the rack attachments 50. The upper parts of the upper beam members 31-34, the grid members 41-43 (44), and the rack attachments 50 form a flat mounting surface. As a result, an item 200 can be placed on the mounting surface as shown by the dashed lines in Figure 6. At this time, since the connecting members 53 of the rack attachments 50 are located near the four corners of the mounting surface, the corners of the rectangular or cubic item 200 can be supported, and the item itself can be supported stably. Furthermore, by forming a grid inside the mounting surface with beam members, the gaps on the mounting surface are made smaller, and the item 200 can be supported more stably.
[0023] Furthermore, by attaching rack attachments 50 near the corners of the mounting surface and connecting the beam members 31 to 34, deflection of the mounting surface, which is the upper surface of the rack 1, can be suppressed. As a result, the strength of the rack 1 itself can be increased.
[0024] Furthermore, the rack attachment 50 in this disclosure can be attached to an existing rack 1. As a result, it is possible to prevent deflection of the rack 1 and improve its strength at a low cost, thereby enabling stable support of articles by the rack 1.
[0025] In the above example, rack attachments 50 are provided at all four corners of the mounting surface, which is the upper surface of rack 1. However, it is not necessary to provide rack attachments 50 at all corners; they may be provided at only some corners. Furthermore, the grid members provided on the mounting surface are not limited to the shape described above, and may be of any shape and composed of any number of beam members.
[0026] Furthermore, although the shape of the mounting surface, which is the upper surface of the rack 1 described above, was explained as being approximately square or rectangular, it may be any shape. In other words, the upper beam members forming the outer perimeter of the mounting surface may be connected to each other at any angle, and the rack attachment 50 may be mounted between them. Moreover, the rack 1 to which the rack attachment 50 is mounted is not limited to the structure disclosed in Figures 1 and 2, but may be any structure.
[0027] Furthermore, the above-mentioned rack 1 can be stacked. Specifically, Figure 7 shows how the racks are stacked. Note that, although the upper rack 1' and the lower rack 1 are the same, for the sake of explanation, the upper rack 1' will be indicated by a different reference number.
[0028] As shown in this figure, when stacking racks 1 and 1', first on the front side, the lower ends of the front support members 11' and 12' of the upper rack 1' are stacked on top of the upper ends of the front support members 11 and 12 of the lower rack 1. At this time, the semi-spherical protrusions on the lower ends of the upper support members 11' and 12' fit into the semi-spherical recesses on the upper ends of the lower support members 11 and 12. On the rear side, the beam member 23' located at the lower end of the upper rack 1' is placed on the beam member 33 located on the upper surface of the lower rack 1. At this time, as shown in Figure 1, stoppers 61 and 62 are provided near both ends of the beam member 33 located on the rear side of the upper surface (mounting surface) of rack 1, respectively, protruding above the mounting surface. Since these stoppers 61 and 62 are located outside the outer circumference of the upper surface (mounting surface) of rack 1, by placing the beam member 23' of the upper rack 1' inside of these stoppers, it is possible to suppress misalignment of the front and rear racks and stabilize the stacked state.
[0029] In this way, by stacking racks 1 and 1', items can be stored inside the lower rack 1, on the upper surface of the lower rack 1 (i.e., the mounting surface of the upper rack 1'), and on the upper surface of the upper rack 1' (i.e., the mounting surface of the upper rack 1').
[0030] In the above example, the rack attachment 50 is attached to the upper beam members 31-34 that form the mounting surface on the upper surface of the rack 1. However, the rack attachment 50 may also be attached to the lower beam members 22, 23, and 24 that form the lower surface of the rack 1. In this case, the rack 1 may also be provided with four lower beam members that horizontally connect the entire perimeter between the lower ends of the support members 11-14, and a mounting surface that is a horizontal plane similar to the upper surface described above may be formed on the lower surface formed by these lower beam members. In other words, a mounting surface having a grid member may be formed on the lower surface of the rack 1. The rack attachment 50 described above may then be attached to the corners of the mounting surface formed on the lower surface of the rack 1. The mounting surface of the rack 1 may be formed at any height position between the upper and lower surfaces of the rack 1, and the rack attachment 50 may be attached to the corners of such a mounting surface.
[0031] Here, the beam members and other members that make up rack 1 described above are mainly connected (joined) by welding, but they may be connected by any method, such as adhesive or by using fasteners such as bolts.
[0032] Although the present disclosure has been described above with reference to the embodiments described above, the present disclosure is not limited to the embodiments described above. Various modifications to the structure and details of the present disclosure can be made that will be understood by those skilled in the art within the scope of the present disclosure.
