[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. Rack 1 in this embodiment is formed in a substantially rectangular parallelepiped shape or a 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 a 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 a 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] Inside the outer periphery of the placement surface surrounded by the four upper end beam members 31, 32, 33, and 34, a lattice-like lattice member formed by beam members 41, 42, and 43 that connect between the upper end beam members facing each other is provided. Specifically, the lattice member includes two beam members 41 and 42 that are located on both sides of the rack 1 and connect between the opposing upper end beam members 32 and 34 and extend in the width direction of the rack 1, and one beam member 43 that is located on the front side and the back side of the rack 1 and connects between the opposing upper end beam members 31 and 33 and extends in the front-rear direction of the rack 1. The beam members cross and are connected to form the lattice member. One beam member 43 that connects between the front side and the back side of the rack 1 is cut at the intersection with the two beam members 41 and 42 that connect between both sides and is butt-jointed. 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 periphery, a flat placement surface is formed.

[0014] Note that the number of beam members forming the above-described lattice member is not limited to the above-described number. For example, the beam member 43 extending along the front-rear direction of the rack is not limited to one and may be two. In this case, the two beam members that connect between the front side and the back side of the rack 1 are each cut at the intersection with the two beam members 41 and 42 that connect between both sides and are butt-jointed. Furthermore, the beam member extending along the front-rear direction of the rack is not limited to one or two and 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 and may be one or three or more.

[0015] Furthermore, connecting attachments 50 (connectors) are fitted to each of the four corners located at the outer perimeter 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 adjacent to each other at a right angle and connected to one another, and connecting attachments 50 are fitted to each other at locations other than the connection point. For example, two upper beam members 31 and 32 are connected at a right angle to each other to form a corner, and the connecting attachment 50 is fitted inside the end of this corner. In this case, the connecting attachments 50 fitted to each corner have the same configuration. Here, the configuration of the connecting attachment 50 fitted to the corner formed between one upper beam member 31 and the other upper beam member 32 will be explained mainly with reference to Figure 2. Figure 2(2-1) shows a perspective view of the connecting attachment 50 from above, and Figure 2(2-2) shows a perspective view from below.

[0016] The connecting attachment 50 comprises a pair of first mounting parts 51 and second mounting parts 52, and a connecting member 53 that connects the pair of mounting parts 51 and 52. Here, the first mounting part 51 is attached to one upper beam member 31, and the second mounting part 52 is attached to the other upper beam member 32. The first mounting part 51 and the second mounting part 52 are formed in a substantially U-shape with an opening at the bottom so as to cover the upper surface and both sides of the mounting location on the upper beam members 31 and 32. Specifically, as shown in Figure 2, the first mounting part 51 comprises a plate-shaped upper surface part 51a formed along the horizontal direction, and plate-shaped side parts 51b and 51c that are connected to both sides of the upper surface part 51a and formed along the vertical direction. In other words, the first mounting portion 51 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 an upper surface portion 51a and the bent ends forming side portions 51b and 51c, respectively. In this case, since the upper beam member 31 to be mounted is a square timber, the first mounting portion 51 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 51a and the side portions 51b and 51c. As a result, the first mounting portion 51 can be mounted to the upper beam member 31 from above by inserting the mounting location of the upper beam member 31 into the internal cavity. The first mounting portion 51 is positioned so that the upper surface of the mounting location of the upper beam member 31 is covered by the upper surface portion 51a, and both side sides are covered by the side portions 51b and 51c, respectively. The length between the connection points of the upper surface portion 51a and the side portions 51b, 51b, and the length from the connection point of the side portions 51b, 51c to the end of the upper surface portion 51a are formed to be approximately the same as the width of the upper end beam member 31, which is a square timber, but they may be formed to any length.

[0017] Also, the second mounting portion 52 is configured in the same manner as the above-described first mounting portion 51. That is, as shown in FIG. 2, the second mounting portion 52 includes a plate-shaped upper surface portion 52a formed along the horizontal direction, and plate-shaped side surface portions 52b and 52c respectively connected to both side portions of the upper surface portion 52a and formed along the vertical direction. In other words, the second mounting portion 52 is formed such that both end sides in the longitudinal direction of a plate-shaped member having a predetermined length are bent at right angles, the central portion forms the upper surface portion 52a, and the bent end portions respectively form the side surface portions 52b and 52c. At this time, since the upper end beam member 32 to be mounted is an angle member, the second mounting portion 52 is formed in a substantially U-shaped manner with an open lower side, and an internal cavity portion surrounded in three directions by the upper surface portion 52a and the side surface portions 52b and 52c is formed. Thereby, the second mounting portion 52 can be mounted on the upper end beam member 32 from above by inserting the mounting location of the upper end beam member 32 into the internal cavity portion. And the second mounting portion 52 is arranged to cover the upper surface side at the mounting location of the upper end beam member 32 with the upper surface portion 52a and cover both side surface sides with the side surface portions 52b and 52c respectively. Note that the length between the connection locations of the upper surface portion 52a with the side surface portions 52b and 52b, and the length from the connection location of the side surface portions 52b and 52c with the upper surface portion 52a to the end portions are formed to be substantially the same as the width of the upper end beam member 32 which is an angle member, but they may be formed to have any length.

[0018] Furthermore, the connecting member 53 constituting the connecting attachment 50 is formed to have a predetermined length and connects the respective side surfaces 51c and 52c of the paired first mounting portion 51 and second mounting portion 52. Specifically, as shown in Figure 1, both ends of the connecting member 53 in the longitudinal direction are joined by welding or the like to the side surfaces 51c of the first mounting portion 51 and 52c of the second mounting portion 52, respectively, which are located on the inside side of the corner formed between the upper beam members 31 and 32. In particular, the longitudinal direction of the connecting member 53 is connected at a 45-degree angle to the plane formed by the respective side surfaces 51c and 52c of the first mounting portion 51 and second mounting portion 52. To further elaborate on this configuration, first, the inner surfaces of the side portions 51c and 52c of the first mounting portion 51 and the second mounting portion 52, located on the inner side of the corner, are contact surfaces that come into contact with the outer surfaces of the mounting locations of the upper beam members 31 and 32, respectively, and these contact surfaces are formed along the longitudinal direction of the upper beam members 31 and 32. The connecting member 53 is positioned such that its longitudinal direction forms a 45-degree angle with the surfaces formed by the side portions 51c and 52c of the first mounting portion 51 and the second mounting portion 52, i.e., the contact surfaces with the upper beam members 31 and 32, and is connected to the outer surfaces of the side portions 51c and 52c. As a result, as shown in Figure 1, when the connecting attachment 50 is mounted on the rack 1, the connecting member 53 is positioned at a 45-degree angle with respect to the longitudinal direction of the upper beam members 31 and 32 that form the corner. However, the connecting member 53 is not necessarily limited to being positioned at a 45-degree angle with respect to the longitudinal direction of the upper beam members 31 and 32. For example, it may be connected at an angle between 40 and 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 connecting 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 connecting 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 Figure 1, it becomes possible to attach the connecting 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 connecting 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 connecting attachment 50 at each of the four corners. However, the length of the connecting member 53 in the longitudinal direction may be formed to any length.

[0021] As shown in Figure 1, the connecting 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 connecting 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 of the connecting attachment 50, 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 connecting 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 the connecting attachments 50 to the four corners of the mounting surface, which is the upper surface of the rack 1, each corner is formed into a triangular shape by the upper beam members 31-34 and the connecting members 53 of the connecting attachments 50. The upper parts of the upper beam members 31-34, the grid members 41-43 (44), and the connecting attachments 50 form a flat mounting surface. As a result, luggage 200 can be placed on the mounting surface as shown by the dashed lines in Figure 7. At this time, since the connecting members 53 of the connecting attachments 50 are located near the four corners of the mounting surface, the corners of the rectangular or cubic luggage 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 luggage 200 can be supported more stably.

[0023] Furthermore, by attaching connecting 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 connecting 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 achieving stable support of articles by the rack 1.

[0025] In the above example, connecting 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 connecting attachments 50 at all corners; they may be provided at only some corners. Furthermore, the lattice 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 connecting attachment 50 may be mounted between them. Moreover, the rack 1 to which the connecting attachment 50 is mounted is not limited to the structure disclosed in Figure 1, but may be any structure.

[0027] Furthermore, the above-mentioned rack 1 can be stacked. Specifically, Figure 3 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 provided 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 connecting 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 connecting 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 similar to the upper surface described above may be formed on the lower surface perimeter 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 connecting attachment 50 described above may 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 connecting attachment 50 may be attached to the corners of such a mounting surface.

[0031] Next, the luggage stopper 100, which is a rack attachment mounted on the rack 1 in this disclosure, will be described. As shown in Figure 1, the luggage stopper 100 is mounted on the upper beam member 31 that forms the outer circumference of the mounting surface, which is the upper surface of the rack 1. In Figure 1, the luggage stopper 100 is mounted on the upper beam member 31 located on the front side, but it can also be mounted on the other upper beam members 32 to 34. Also, although two luggage stoppers 100 are shown in Figure 1, they both have the same configuration. Here, the specific configuration of the luggage stopper 100 will be described mainly with reference to Figures 4 to 6.

[0032] Figure 4 is a schematic perspective view showing the external configuration of the cargo stopper 100. Figures 5 and 6 are schematic side views showing the external configuration of the cargo stopper 100 shown in Figure 4 attached to the upper beam member 31. The cargo stopper 100 is a device for preventing displacement and falling of cargo 200 placed on the rack 1. The cargo 200 is the object stored by the rack 1. In this embodiment, the cargo 200 is described as being made up of a pallet formed in the shape of a plate. However, the cargo 200 may include articles placed on a pallet, or it may be cargo 200 as shown in Figure 7 that is placed directly on the rack 1 without a pallet.

[0033] As shown in Figure 4, the luggage stopper 100 mainly comprises a mounting base 101, a stopper body 110, and a rotating support 120. The mounting base 101 is a component for attaching the luggage stopper 100 to the upper end beam member 31 of the rack 1, and is formed in a shape that fits onto the upper end beam member 31 from above. More specifically, as shown in Figure 5, the mounting base 101 is configured to have an upper surface facing surface 101a, an outer surface facing surface 101b, and an inner surface facing surface 101c, respectively, which face the upper surface 91a, outer surface 91b (the surface facing the outside of the rack 1), and inner surface 91c (the surface facing the inside of the rack 1) of the upper end beam member 31.

[0034] The upper opposing surface 101a is the part that rests on the upper surface 91a of the upper end beam member 31 and to which the plate-like body 122 of the rotating support 120 (described later) is fixed, and is formed as a flat plate extending in the horizontal direction. In this case, the width of the upper opposing surface 101a (length in the Y-axis direction shown) is formed to be approximately the same length as the width of the upper surface 91a of the upper end beam member 31. Also, the length of the upper opposing surface 101a in the X-axis direction shown is formed to be slightly shorter than the length of the stopper body 110. Note that the length of the upper opposing surface 101a in the X-axis direction shown may be the same length as the length of the stopper body 110, or longer than the length of the stopper body 110.

[0035] The outer opposing surface 101b faces the outside of the rack 1 on the upper end beam member 31 and is the portion to which the plate-like body 123 on the rotating support 120 is fixed, and is formed as a flat plate extending in the vertical direction. In this case, the vertical length of the outer opposing surface 101b (length in the Z-axis direction shown) is formed to extend downward to a position facing the lower end 112a of the stopper body 110.

[0036] The inner opposing surface 101c is the portion of the upper end beam member 31 that faces the inside of the rack 1, and is formed as a flat plate extending vertically. In this case, the vertical length of the inner opposing surface 101c (length in the Z-axis direction as shown) is formed to be the same length as the opposing outer opposing surface 101b. However, the vertical length of the inner opposing surface 101c (length in the Z-axis direction as shown) may be shorter or longer than the opposing outer opposing surface 101b.

[0037] The mounting base 101 described above is formed by press working, which involves bending a metal plate so that its cross-sectional shape is U-shaped. In this case, the distance between the outer opposing surface 101b and the inner opposing surface 101c of the mounting base 101 is formed to be approximately the same as the distance between the outer surface 91b and the inner surface 91c of the upper beam member 31. As a result, the mounting base 101 can be fitted onto the upper beam member 31 without any looseness.

[0038] The mounting base 101 may be formed so that the outer opposing surface 101b and the inner opposing surface 101c are parallel to each other, but by forming them with a slight inward inclination at the lower ends of both surfaces, the upper beam member 31 can be sandwiched, improving the mounting force. Alternatively, the mounting base 101 can be formed by forming the upper opposing surface 101a, the outer opposing surface 101b, and the inner opposing surface 101c in separate processes and then connecting them to each other by welding.

[0039] The stopper body 110 is a component that prevents the load 200 placed on the rack 1 from shifting position or falling, and is formed in the shape of a plate that stands vertically adjacent to the mounting base 101. Specifically, the stopper body 110 is composed of an upper body 111 and a lower body 112.

[0040] The upper body 111 is the part that abuts against (bumps into or contacts) the luggage 200 placed on the rack 1 to prevent the luggage 200 from shifting position or falling, and is formed as a plate that protrudes upward from the upper surface 101a of the mounting base 101. In this case, the upper body 111 is formed as a flat plate that is inclined toward the mounting base 101 side with respect to the vertical direction, that is, toward the luggage 200 placed on the rack 1. In this embodiment, the upper body 111 is formed with an inclination of 15° with respect to the vertical direction. The inclination angle of the upper body 111 is preferably greater than 0 degrees and 45 degrees or less with respect to the vertical direction.

[0041] The lower body 112 is a part that allows the upper body 111 to stand upright and restricts rotation of the upper body 111 in the opposite direction to the inclination direction, and is formed in the shape of a plate. More specifically, the lower body 112 is formed in the shape of a flat plate extending in the vertical direction. In this case, the lower body 112 is composed of a mass heavier than the mass of the upper body 111. Furthermore, the lower end portion 112a of the lower body 112 is formed by bending at a right angle toward the outer opposing surface 101b of the mounting base 101.

[0042] The stopper body 110 described above is formed by press working, which involves bending a metal plate. Alternatively, the stopper body 110 can be formed by forming the upper body 111 and the lower body 112 separately and then joining them together by welding. Furthermore, the stopper body 110 can also be constructed by adding a weight (not shown) to the lower body 112 so that the lower body 112 is heavier than the upper body 111.

[0043] The rotating support 120, as shown in Figures 5 and 6, is a component for rotatably supporting the stopper body 110 with respect to the mounting base 101, and is provided between the upper end and lower end 112a of the stopper body 110. In this embodiment, the rotating support 120 is made of a metal hinge. More specifically, the rotating support 120 is made of two plate-like bodies 122 and 123 connected to each other via a pin 121.

[0044] Pin 121 is a component that connects the two plate-like bodies 122 and 123 in a manner that allows them to rotate relative to each other, and is made of a round metal rod. Plate-like body 122 is a component that is fixedly attached to the upper opposing surface 101a of the mounting base 101, and is made of a metal plate. In this case, plate-like body 122 is formed to cover more than half of the width direction (length in the Y-axis direction shown) of the upper opposing surface 101a.

[0045] The plate-like body 123 is a component that is fixedly attached to the back surface of the lower body 112 of the stopper body 110, which is the surface facing the mounting base 101, and is made of a metal plate. In this case, the plate-like body 123 is sized to cover almost the entire back surface of the lower body 112.

[0046] The plate-like bodies 122 and 123 described above are fixed to the mounting base 101 by welding. The rotating support 120 can also be fixedly attached to the outer opposing surface 101b of the mounting base 101 instead of the upper opposing surface 101a of the mounting base 101.

[0047] Here, the mounting base 101 described above is attached to the upper beam member 31 of the rack 1 as shown in Figure 1, but is positioned between the other upper beam members 32 and 34 connected to the upper beam member 31 and the beam member 43 which is a grid member. Furthermore, the mounting base 101 is positioned so as not to come into contact with the connecting attachment 50 provided between the upper beam members 31 to 34 which form the mounting surface, which is the upper surface of the rack 1. For this reason, the length of the upper surface facing surface 101a of the mounting base 101 shown in Figure 2 in the X-axis direction, that is, the length along the longitudinal direction of the upper beam member 31 when it is attached to the upper beam member 31 of the rack 1, is formed so as not to come into contact with any of the other upper beam members 32 and 34 connected to the upper beam member 31, the beam member 43 which is a grid member, and the connecting attachment 50. In other words, the length of the upper beam member 31 along its longitudinal direction when attached to the mounting base 101 is shorter than the distance between the other upper beam members 32, 34 connected to the upper beam member 31 and the beam member 43 which is a grid member, the distance between the beam member 43 which is a grid member and the connecting attachment 50, and further, the distance between the other upper beam members 32, 34 and the connecting attachment 50. That is, the length of the upper beam member 31 along its longitudinal direction when attached to the mounting base 101 is such that it can be fitted between other members connected to the upper beam member 31. Although not shown in Figure 1, the mounting base 101 of the luggage stopper 100 can also be attached to the upper beam members 32 and 34 located on the side of the rack 1. In this case, the length of the mounting base 101 along the longitudinal direction of the upper beam members 32 and 34 is formed to be shorter than the distance between it and the beam members 41 and 42, which are grid members.

[0048] Next, the operation of the luggage stopper 100 configured in this way will be described. When a worker places luggage 200 on the rack 1, they first prepare the luggage stopper 100. In this case, the worker prepares a number of luggage stoppers 100 corresponding to the size of the luggage 200 and the rack 1. In this embodiment, the worker prepares two luggage stoppers 100.

[0049] Next, the worker attaches the cargo stoppers 100 to the rack 1. Specifically, as shown in Figures 1 and 5, the worker fits the mounting bases 101 of the two cargo stoppers 100 onto the upper beam member 31 of the rack 1 from above the upper beam member 31. In this case, the worker positions each cargo stopper 100 at a location corresponding to the position of the cargo 200 placed on the upper beam member 31, that is, at a position opposite to the cargo 200. At this time, the worker positions each cargo stopper 100 by fitting it between other members connected to the upper beam member 31.

[0050] As a result, each cargo stopper 100 is mounted on the upper beam member 31 with the stopper body 110 in an upright position, as shown in Figure 5. Alternatively, the worker can position the mounting base 101 in the appropriate location by fitting it into an appropriate position on the upper beam member 31 and then sliding the mounting base 101 on the upper beam member 31.

[0051] Next, the worker places the load 200 onto the rack 1. Specifically, the worker places the load 200 onto the rack 1 using their hands or a forklift. Specifically, the worker can place the load 200 from above the rack 1 so that it does not come into contact with the load stopper 100. In this load placement operation, the worker may mistakenly place the load 200 on the upper body 111 of the stopper body 110, as shown in Figure 6(6-1).

[0052] In this case, the luggage stopper 100 is configured such that the upper body 111 is tilted toward the upper surface 101a of the mounting base 101, and the stopper body 110 is rotatable by the rotating support 120. As a result, the stopper body 110 rotates clockwise (see dashed arrow in the figure) around the pin 121 of the rotating support 120 as the pivot point, and as shown in Figure 6(6-2), the upper body 111 rotates toward the mounting base 101 and is placed on the plate-like body 122 of the rotating support 120. This prevents damage to the luggage 200.

[0053] Furthermore, as shown in Figure 6(6-2), the worker can push the side of the luggage 200 towards the upper body 111 of the luggage stopper 100 to place the luggage 200 on the rack 1 (see dashed arrow). In this case, as described above, the luggage stopper 100 is configured so that the stopper body 110 is rotatable by the rotating support 120. As a result, the stopper body 110 rotates clockwise around the pin 121 of the rotating support 120 as the pivot point, and the upper body 111 rotates toward the mounting base 101 and is placed on the plate-like body 122 of the rotating support 120. This allows the luggage 200 to be smoothly moved and placed on the rack 1. In this case, since the stopper body 110 is formed with the upper body 111 bent relative to the lower body 112, when the upper body 111 abuts against the plate-like body 122, the lower body 112 does not collide with the bottom surface of the cargo 200, thereby preventing the generation of collision noise and damage to the cargo 200.

[0054] The worker then moves the load 200 to a position where it has finished passing over the stopper body 110. As a result, the load on the upper body 111 of the stopper body 110 is relieved, and as shown in Figures 5 and 7, the weight of the lower body 112 causes it to rotate in the opposite direction to when it was tilted, returning it to an upright position. In this case, if the load 200 remains on the upper body 111, the load stopper 100 will be in a position where the lower body 112 extends horizontally from a hanging position, as shown in Figure 6(6-2). This allows the worker to easily recognize whether or not the load 200 is on the upper body 111.

[0055] The worker may position the load 200 at the location where it has passed over the stopper body 110, or, after the load 200 has passed over the stopper body 110 and the stopper body 110 has returned to its upright position, the worker may move the load 200 again towards the upper body 111 and position it near the upper body 111 or in contact with the upper body 111. This completes the worker's task of placing the load 200 on the rack 1.

[0056] As described above, by placing the cargo 200 on the rack 1, the cargo stopper 100 prevents the cargo 200 placed on the rack 1 from shifting position or falling, as shown in Figure 7. Specifically, even if the cargo 200 presses against the upper body 111 of the stopper body 110 due to an earthquake or contact during loading or unloading of other cargo, the lower end 112a of the lower body 112 of the stopper body 110 is pressed against the outer opposing surface 101b of the mounting base 101, preventing the cargo 200 from shifting position beyond the upper body 111.

[0057] Next, the worker removes the load 200 from rack 1. Specifically, the worker can remove the load 200 from rack 1 by hand or using a forklift. In this case, the worker can remove the load 200 by lifting it above the load stopper 100 so that it does not come into contact with the load stopper 100. In this case, if the load 200 were to come into contact with the stopper body 110, the load stopper 100 would rotate, causing the upper body 111 to tilt onto the plate-like body 122. Once the load 200 has passed, the weight of the lower body 112 will cause the stopper body 110 to return to an upright position.

[0058] Next, the worker can remove the cargo stopper 100 from the rack 1. Specifically, the worker can remove the cargo stopper 100 from the rack 1 by pulling the mounting base 101 of the cargo stopper 100 upward from the upper beam member 31. The worker can then reuse the removed cargo stopper 100 on the same or a different rack 1. Alternatively, instead of removing the cargo stopper 100, the worker can reuse it by changing its position on the upper beam member 31.

[0059] As can be understood from the above description of operation, according to the above embodiment, the luggage stopper 100 is configured such that the upper body 111, which extends upward from the upper surface of the upper end beam member 31, is tilted toward the mounting base 101 with respect to the vertical direction. Therefore, if a part of the luggage 200, such as the front end, is mistakenly placed on the upper body 111, the stopper body 110 immediately tilts toward the upper end beam member 31, causing the lower body 112 of the stopper body 110 to spring up, allowing the worker to easily recognize that a part of the luggage 200 has been placed on the stopper body 110. Furthermore, in this case, since the lower body 112 of the luggage stopper 100 is formed to bend relative to the upper body 111, the lower body 112 does not collide with the bottom surface of the luggage 200 when it springs up, thus preventing damage to the luggage 200 and preventing the sudden occurrence of a loud collision noise.

[0060] In the above configuration, the luggage stopper 100 is attached to the upper beam member 31 by fitting a U-shaped mounting base 101 onto it from above. In this case, the mounting base 101 is fitted to the upper beam member 31 without any looseness and is slidably attached. This allows the luggage stopper 100 to be easily attached to and detached from the upper beam member 31 and its mounting position to be changed. However, the luggage stopper 100 can also be configured so that the mounting base 101 is fixedly attached to the upper beam member 31 using screws, bolts, or belts.

[0061] Furthermore, in the above embodiment, the luggage stopper 100 is constructed by bending the lower end portion 112a of the stopper body 110 at a right angle toward the outer opposing surface 101b of the mounting base 101. However, the luggage stopper 100 can also be constructed by bending the lower end portion 112a of the stopper body 110 toward the outer opposing surface 101b of the mounting base 101 at an angle less than or greater than a right angle. Alternatively, the luggage stopper 100 can also be constructed in a straight line without bending the lower end portion 112a of the stopper body 110 toward the outer opposing surface 101b of the mounting base 101.

[0062] Furthermore, although the rotating support 120 is configured with a hinge in the above embodiment, the rotating support 120 only needs to be configured to rotatably support the stopper body 110 with respect to the mounting base 101. Therefore, the rotating support 120 can also be configured to have bearing portions consisting of through holes that rotatably support the pin 121 in the stopper body 110 and the mounting base 101, respectively.

[0063] Furthermore, in the above embodiment, each beam member in the rack 1 is formed with a square cross-sectional shape. However, the cross-sectional shape of each beam member constituting the rack 1 is not limited to the above embodiment and may be formed with a rectangle or other shape, such as an irregular polygon formed by combining two different quadrilateral shapes.

[0064] Furthermore, although the beam members and other components that make up the rack 1 described above are mainly connected (joined) by welding, they may be connected by any method, such as adhesive or by using fasteners such as bolts.

[0065] 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.
