Description

[Technical field]

[0001] The present disclosure relates to a mounting tool and a mounting structure for mounting a box body to a truck bed. More specifically, the present disclosure relates to a mounting tool and a mounting structure for detachably mounting a box body to a truck bed having a female hinge for mounting a side panel provided on the side. [Background technology]

[0002] In the bed of a truck, including a light truck, side panels are generally removably attached to both the left and right sides and the rear side to prevent cargo from falling. For example, a hinge ring (female hinge) is provided on the side of the bed of a truck disclosed in the following Patent Document 1, and a side gate or the like is removably attached to the bed so as to be able to rotate outwardly by inserting a hinge pin (of a male hinge) fixed to a side gate and a rear gate (side panel) into a hole (shaft hole) in the hinge ring. When the side gate or the like is removed, the hinge ring is left on the side of the bed with the hole (shaft hole) empty.

[0003] In recent years, there has been an increasing need to attach large boxes such as containers and shells to the bed of trucks, such as kitchen cars and campers. For example, the following Patent Document 2 discloses a structure for attaching and detaching a shell to the bed of a light truck. In this structure, fixing metal fittings having a thickness that fits into the gap between the gate (side plate) and the bed are fixed so as to protrude outward from the bottom of the left and right sides of the shell (box body). After the gate is tilted outward to place the shell on the bed, the fixing metal fittings are clamped in the gap by raising the gate, and the gate can be further tilted to remove the shell. Here, the fixing metal fittings are arranged at a position overlapping with a hinge (hinge mechanism) that connects the gate and the bed. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiment of the mounting tool and mounting structure according to the present disclosure will be specifically described with reference to the drawings. The present disclosure is not limited to the following examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope of the claims. The drawings are basically drawn so that the top of the paper is up and the bottom is down, and some drawings are accompanied by arrows indicating front, back, left, and right. In addition, for multiple identical components, a reference number may be given to one component and the reference numbers of other components may be omitted. The relative dimensions and arrangement of the components in each drawing are not necessarily accurate, and some components have been scaled or the like changed for convenience of explanation.

[0012] <Existing structure> A tailgate plate is generally attached detachably around the bed of a truck, including a light truck, via a hinge mechanism. The mounting tool and mounting structure according to the present disclosure utilize a female hinge for mounting the tailgate plate already provided on the side of the bed of the truck. First, an existing structure for mounting the tailgate plate 7 to the bed 9 provided on a conventional light truck 1 will be described with reference to FIG. 5. Here, the light truck 1 will be described as an example, but the trucks to which the present technology can be applied are not limited by size, etc., and the present technology can also be applied to relatively large trucks as long as a female hinge for mounting the tailgate plate is provided on the side of the bed.

[0013] As shown in FIG. 5(A), a tailgate 7 for preventing a load from falling is detachably attached to the left, right, and rear sides of the bed 9 of the light truck 1. The tailgate 7 is usually attached by a plurality of hinge mechanisms 10 provided at intervals along the left, right, and rear edges of the bed 9. On the left side of the light truck 1 illustrated in the figure, three hinge mechanisms 10, a first hinge mechanism 10A, a second hinge mechanism 10B, and a third hinge mechanism 10C, are provided from the rear along the left edge of the bed 9. In the following description, the first hinge mechanism 10A provided on the left side of the bed 9 will be mainly described, but the basic structure of each hinge mechanism 10 is the same.

[0014] As shown in Fig. 5(B), the first hinge mechanism 10A includes a first female hinge 11A fixed to the left edge of the loading platform 9, and a male hinge 15 fixed to the lower end of the tailgate 7. Inside the first female hinge 11A, which is an example of the female hinge 11, a through shaft hole 13 is formed that penetrates it in the front-rear direction along the left edge, while a round bar-shaped hinge pin 17 is extended from the male hinge 15. By inserting the hinge pin 17 into the through shaft hole 13, the male hinge 15 is journaled on the first female hinge 11A, and the tailgate 7 is attached detachably and rotatably outwardly (leftward in the left side portion) with respect to the loading platform 9.

[0015] Usually, in each of the multiple hinge mechanisms 10 provided on the same side of the loading platform 9, the hinge pins 17 are all inserted into the through shaft holes 13 from the same direction. For example, three hinge mechanisms 10, namely, a first hinge mechanism 10A, a second hinge mechanism 10B, and a third hinge mechanism 10C, are provided on the left side of the light truck 1 illustrated in FIG. 5(A), and a total of three male hinges 15 are fixed to the lower end of the tailgate 7 attached by these hinge mechanisms at a total of three locations corresponding to the female hinges 11 associated with the hinge mechanisms 10A to 10C. All of the hinge pins 17 of the male hinges 15 associated with the hinge mechanisms 10A to 10C are inserted into the through shaft holes 13 of the corresponding female hinges 11 from the rear, and the tailgate 7 is attached to the left side of the loading platform 9 by inserting it from the left side and sliding it from the rear to the front.

[0016] The light truck 1 to which the tailgate 7 is attached in this manner is provided with a structure for restricting the movement of the tailgate 7 to prevent it from falling off. For example, the light truck 1 shown in Fig. 5(B) is provided with a retaining bolt 3 on the left side of the bed 9 in a position near the rear end of the male hinge 15 having the hinge pin 17 inserted into the through shaft hole 13 of the first female hinge 11A. By fastening the retaining bolt 3 after inserting the hinge pin 17 into the through shaft hole 13 to attach the tailgate 7 to the bed 9, the rearward displacement of the male hinge 15 is restricted and the tailgate 7 is prevented from falling off the bed 9.

[0017] Similarly, the three gate plates 7 attached to the right side and rear side of the cargo bed 9 are each rotated inward (towards the cargo bed 9) so as to surround the top surface (cargo loading surface) of the cargo bed 9 from three sides and stand up vertically, as shown in Figure 5(A), and are connected to each other by locking fittings 5 ​​provided at the longitudinal ends of each gate plate 7, and the corners are fixed.

[0018] The gate plate 7 can be removed from the loading platform 9 by reversing the above procedure. That is, after the connection by the locking metal fittings 5 ​​is released, each gate plate 7 is tilted outward, and the retaining bolts 3 are loosened and removed. Next, each gate plate 7 is slid in the opposite direction to the insertion direction (for example, rearward in the case of the left side gate plate 7 that is attached by sliding forward as described above), the hinge pin 17 of each hinge mechanism 10 is pulled out from the through shaft hole 13, and the gate plate 7 is removed. When the gate plate 7 is removed from the loading platform 9, the female hinge 11 with the inside of the through shaft hole 13 being empty is left on the side of the loading platform 9. In the technology according to the present disclosure, the box body 6 is attached to the loading platform 9 by utilizing this female hinge 11.

[0019] <Embodiment> Hereinafter, a mounting structure 100 according to one embodiment will be described with reference to FIGS. FIG. 1 is a perspective view of a light truck 1 with a box body 6 attached to a bed 9 by an attachment structure 100. Examples of the box body 6 include a container for storing luggage, a shell used as a kitchen area of ​​a kitchen car or a living area of ​​a camper, and the like. However, the present technology is not particularly limited and can be applied to boxes used for various purposes. Considering the space utilization efficiency and ease of attachment to the bed 9, the box body 6 preferably has a rectangular parallelepiped outer shape whose horizontal cross section has approximately the same dimensions and shape as the upper surface of the bed 9, and more preferably has an outer shape whose horizontal cross section is one size smaller than the upper surface of the bed 9.

[0020] As shown in FIG. 1, the box body 6 according to this embodiment is provided with side grooves 610 at the lower parts of the left side, right side, and rear side. The side grooves 610 are provided so as to open outward (leftward in the left side part) and extend along the side edge of the loading platform 9 (left edge in the left side part) when the box body 6 is loaded on the loading platform 9 of the light truck 1. Although not limited thereto, for example, a C-shaped channel material may be used as a frame material constituting the lower part of the box body 6, and the opening of the C-shaped channel material may be directed outward to form the side grooves 610 (see FIG. 4). From the viewpoint of ensuring sufficient strength while reducing the weight of the box body 6, for example, an aluminum C-shaped channel material can be preferably used. A sliding member 630 (see FIG. 3 and FIG. 4) is slidably fitted inside the side groove 610.

[0021] In the following description, a mounting structure 100 will be described that includes a first mounting fixture 101A that utilizes a first female hinge 11A associated with a first hinge mechanism 10A and a second mounting fixture 101B that utilizes a second female hinge 11B associated with a second hinge mechanism 10B, among the three hinge mechanisms 10 on the left side that were previously installed on the loading platform 9 as an existing structure. Of course, the mounting structure 100 may further include a mounting fixture 101 that utilizes a female hinge 11 associated with a third hinge mechanism 10C.

[0022] FIG. 2 is a front view showing a mounting structure 100 according to one embodiment. The mounting structure 100 may include at least one mounting fixture 101, but it is preferable that the mounting structure 100 includes two or more mounting fixtures 101 from the viewpoints of mounting stability and regulating displacement of the box body 6 described later. Here, the mounting structure 100 on the left side is described, but a similar mounting structure 100 can also be applied to the right side and rear side of the loading platform 9. The mounting structure 100 can be provided on only one side of the loading platform 9, but considering mounting stability and the like, it is preferable that the mounting structure 100 is provided on three sides of the loading platform 9, including the two left and right sides and the rear side, and the box body 6 is attached to the loading platform 9 on the three side surfaces.

[0023] As shown in FIG. 2, the mounting structure 100 includes a side groove 610 and a sliding member 630. As shown in the figure, in this embodiment, the sliding member 630 includes a first sliding member 630A slidably fitted inside the side groove 610 and a second sliding member 630B slidably fitted inside the same side groove 610. The shape and material of the sliding member 630 are not particularly limited, but in consideration of wear resistance, strength, weather resistance, and ease of sliding in the side groove 610, for example, a rectangular plate-shaped aluminum material or stainless steel material can be preferably used. The upper member 110 of the mounting tool 101 described later is fixed to the sliding member 630. In this embodiment, each of the first sliding member 630A and the second sliding member 630B is provided with a screw hole 631 (four for each sliding member 630 shown in FIG. 2 to FIG. 4) capable of receiving a fixing member 650 constituted by a butterfly bolt.

[0024] As shown in FIG. 2, the mounting structure 100 also includes mounting fixtures 101. Each mounting fixture 101 includes an upper member 110 fixed to a sliding member 630, a lower member 130 pivotally supported on the platform 9 via a female hinge 11, and a connecting member 150 that connects and fixes the upper member 110 and the lower member 130. As shown in the figure, in this embodiment, the mounting fixtures 101 include a first mounting fixture 101A and a second mounting fixture 101B. Hereinafter, when it is necessary to distinguish between the members constituting the first mounting fixture 101A and the members constituting the second mounting fixture 101B, the suffixes A and B are added to the reference numerals representing the respective members, and when there is no particular need to distinguish between them, the suffixes are not added. The components constituting the first mounting fixture 101A and the components constituting the second mounting fixture 101B are basically of the same structure, but only the lower members 130A and 130B are configured in a three-dimensional shape that is plane-symmetrical. The effects of configuring the lower members 130A and 130B in a plane-symmetrical manner will be described later.

[0025] 2, in the first mounting fixture 101A, the upper member 110A is fixed to the first sliding member 630A by the fixing member 650A, the lower member 130A is pivotally supported by the first female hinge 11A, and the upper member 110A and the lower member 130A are connected by the connecting member 150A. On the other hand, in the second mounting fixture 101B, the upper member 110B is fixed to the second sliding member 630B by the fixing member 650B, the lower member 130B is pivotally supported by the second female hinge 11B, and the upper member 110B and the lower member 130B are connected by the connecting member 150B. In this embodiment, the connecting member 150 is formed by a wing nut, and the fixing member 650 is formed by a wing bolt (see FIG. 4).

[0026] The basic configuration of the mounting fixture 101 will be described based on the first mounting fixture 101A shown in FIGS. As shown in Fig. 4, the upper member 110 according to this embodiment has a basic shape of an L-shaped metal fitting, in which a flat upper base 111 and a flat fixing part 113 are connected to each other so as to be substantially perpendicular via a bent part. In this embodiment, two protruding parts 115 are provided on the plate surface of the upper base 111, protruding on the same side as the fixing part 113, and an external thread capable of receiving a wing nut constituting the connecting member 150 is cut on the outer surface up to the tip 117 of each protruding part 115. In addition, the fixing part 113 is provided with two fixing insertion holes 119 for inserting a fixing member 650 made of a wing bolt toward the screw hole 631 of the sliding member 630.

[0027] As shown in FIG. 3, the upper member 110 is fixed to the sliding member 630 with the upper base 111 placed on the edge of the top surface of the loading platform 9 and the fixing portion 113 aligned along the side surface of the box body 6. In this embodiment, in order to achieve sufficient mounting strength, a reinforcing member 410 having a through hole 411 through which the fixing member 650 can be inserted is interposed between the fixing portion 113 and the sliding member 630. The reinforcing member 410 can be produced, for example, by drilling a through hole 411 (see FIG. 4) in an appropriate location of a steel plate. As shown in FIG. 3 and FIG. 4, the fixing insertion hole 119 according to this embodiment is formed as an elongated hole that is long in the vertical direction, and when the upper member 110 is attached to the sliding member 630 by the fixing member 650, the upper member 110 and the sliding member 630 can be connected while finely adjusting the relative positions of the upper member 110 and the sliding member 630 in the vertical direction.

[0028] As shown in FIG. 4, the lower member 130 according to this embodiment also has a basic shape of an L-shaped metal fitting, in which a flat lower base 131 and a flat side portion 132 are connected to each other so as to be substantially perpendicular via a bent portion. In this embodiment, the lower base 131 is provided with two connecting insertion holes 135 through which the two protruding portions 115 of the upper member 110 can be inserted, respectively. In addition, a round bar-shaped shaft portion 133 is extended from the edge of the side portion 132 opposite to the edge to which the lower base portion 131 is connected in a direction along this edge. The shaft portion 133 is formed to have substantially the same dimensions and shape as the hinge pin 17 provided in the male hinge 15 of the existing structure, and can be smoothly inserted and removed from the through shaft hole 13 of the female hinge 11.

[0029] As shown in Fig. 3, the lower member 130 is pivotally supported by the female hinge 11 in such a position that the protruding portion 115 of the upper member 110 is inserted into the connecting through hole 135, the lower base portion 131 is placed on the upper base portion 111, and the shaft portion 133 is inserted into the through shaft hole 13 so that the side portion 132 is aligned with the side surface of the loading platform 9. As shown in Figs. 3 and 4, the connecting through hole 135 according to this embodiment is formed as an elongated hole that is long in the direction from the edge of the lower base portion 131 to which the side portion 132 is connected toward the edge of the upper member 110 facing the fixed portion 113, and when the lower member 130 and the upper member 110 are connected by the connecting member 150, the degree of overlap between the lower base portion 131 and the upper base portion 111 can be finely adjusted.

[0030] The box 6 can be attached to the bed 9 of the light truck 1 by the mounting fixture 101 having the above-mentioned configuration, for example, in the following mounting procedure. Note that the mounting procedure is not limited to the following. First, the sliding member 630 is moved to a position slightly away from the female hinge 11, and the fixing portion 113 and the sliding member 630 are aligned with the reinforcing member 410 sandwiched therebetween so that the fixing insertion hole 119, the through hole 411, and the screw hole 631 are aligned in a straight line. Then, the fixing member 650 (wing bolt) is lightly tightened with the washer 651 interposed therebetween, and the upper member 110 is temporarily fixed to the sliding member 630 in a manner that does not prevent the sliding of the sliding member 630 in the side groove 610. On the other hand, the lower member 130 is pivotally supported by the female hinge 11 so as to be rotatable by inserting the shaft portion 133 into the through shaft hole 13 with the lower base portion 131 rotated outward. Next, the sliding member 630 to which the upper member 110 is provisionally fixed is slid in the side groove 610 so as to be in a prescribed position relative to the female hinge 11 on which the lower member 130 is pivotally supported. Thereafter, the lower member 130 is rotated to insert the protruding portion 115 into the connecting insertion hole 135 and overlap the lower base portion 131 on the upper base portion 111. Then, the connecting member 150 (wing nut) is attached to the tip 117 side of the protruding portion 115 protruding from the connecting insertion hole 135 with a washer 151 interposed therebetween and lightly screwed in, provisionally connecting the upper member 110 and the lower member 130. After fine-tuning the position of each component using the fixing insertion hole 119 and the connecting insertion hole 135 formed in the elongated hole, the fixing member 650 and the connecting member 150 are tightened to completely fix the upper member 110 to the sliding member 630 while restricting the sliding of the sliding member 630 in the side groove 610, and also completely connect the upper member 110 and the lower member 130 firmly. As a result, the upper member 110 fixed to the box 6 via the sliding member 630 and the lower member 130 attached to the platform 9 via the female hinge 11 are connected and fixed, and the box 6 is attached to the platform 9.

[0031] The box body 6 can be removed from the bed 9 of the light truck 1 by performing the procedure opposite to that of the above-mentioned installation. Specifically, for example, the wing nut and wing bolt constituting the connecting member 150 and the fixing member 650 are loosened and removed, the sliding member 630 is slid in the side groove 610, and the shaft portion 133 of the lower member 130 is pulled out from the through shaft hole 13. Then, the fixing portion 113 of the upper member 110 is removed from the sliding member 630 and the reinforcing member 410, and the protruding portion 115 is pulled out from the connecting insertion hole 135 of the lower member 130. In this manner, the upper member 110, the lower member 130, the connecting member 150, the fixing member 650, the reinforcing member 410, and the like are collected. When the box body 6 is attached to the bed 9 by a plurality of mounting fixtures 101, the box body 6 can be separated from the bed 9 and taken off from the light truck 1 by removing all the mounting fixtures 101. The removal procedure is not limited to the above, and the order of each step can be changed as appropriate.

[0032] Here, as described above, the lower member 130A of the first mounting fixture 101A and the lower member 130B of the second mounting fixture 101B are formed in a shape that is symmetrical with respect to the plane. That is, as shown in FIG. 2, if the shaft portion 133A of the first mounting fixture 101A is inserted into the through shaft hole 13 of the first female hinge 11A from the first direction D1 along the axis of the through shaft hole 13, the shaft portion 133B of the second mounting fixture 101B is formed to be inserted into the through shaft hole 13 of the second female hinge 11B from the second direction D2 directly opposite to the first direction D1. The movement of the first mounting fixture 101A in the first direction D1 is restricted by the first female hinge 11A, and the movement of the second mounting fixture 101B in the second direction D2 is restricted by the second female hinge 11B, so that the movement of the box body 6 in both the first direction D1 and the second direction D2 is restricted. In this way, by including in the mounting structure 100 the first mounting fixture 101A having the lower member 130A and the second mounting fixture 101B having the lower member 130B formed in a shape that is face-symmetrical to the lower member 130A, and making the insertion direction of the shaft portion 133B into the through shaft hole 13 exactly opposite to the insertion direction of the shaft portion 133A into the through shaft hole 13, it becomes possible to restrict the movement of the box body 6 along the mounting side edge on the cargo bed 9 using only the mounting structure 100, without the need for an additional movement restriction structure such as the anti-pullout bolt 3 in the existing structure.

[0033] <Effects of the Configuration of this Embodiment> As described above, the mounting tool 101 according to this embodiment is a mounting tool 101 for detachably mounting a box body 6 to a bed 9 of a light truck (truck) 1 having a female hinge 11 for mounting a tailgate 7 provided on the side thereof, and includes an upper member 110 fixed to the box body 6, a lower member 130 pivotally supported on the bed 9 via the female hinge 11, and a connecting member 101 for connecting and fixing the upper member 110 and the lower member 130. The upper member 110 has a flat upper base 111 and a fixing portion 113 fixed to the box body 6. The lower member 130 has a flat lower base 131 and a shaft portion 133 formed so as to be insertable into and removable from a through shaft hole (shaft hole) 13 extending in the female hinge 11. Either the upper base 111 or the lower base 131 has a connecting insertion hole (insertion hole). The other of the upper base 111 and the lower base 131 is provided with a protruding portion 115 having a protruding end 117 that can be inserted into the connecting insertion hole 135, and the connecting member 150 is formed so as not to be able to be inserted into the connecting insertion hole 135 and so as to be detachably attached to the protruding end 117 side of the protruding portion 115, and the fixing portion 113 is fixed to the box body 6, and the shaft portion 13 is fixed to the box body 6. 3 is inserted into the through shaft hole 13, the protrusion 115 is inserted into the connecting insertion hole 135, and the upper base 111 and the lower base 131 are stacked on the bed 9, and the connecting member 150 is attached to the tip 117 side of the protrusion 115, thereby connecting and fixing the upper member 110 and the lower member 130, so that the box body 6 is attached to the bed 9.

[0034] According to the configuration of the present embodiment, the upper member 110 is fixed (through the sliding member 630) to the box body 6 loaded on the bed 9 of the light truck 1 from which the tailgate 7 has been removed, while the lower member 130 is pivotally supported on the bed 9, and both members 110, 130 are connected and fixed, so that the box body 6 can be detachably attached to the bed 9 by the mounting fixture 101 having a very simple structure. In particular, the lower member 130 is provided with an axle portion 133 that can be inserted into and removed from the through-hole 13 in the female hinge 11, and the lower member 130 is pivotally supported on the bed 9 of the light truck 1 by utilizing the female hinge 11 for mounting the tailgate 7. This allows the box body 6 to be mounted on the bed 9 without modifying the vehicle structure of the light truck 1 itself. As a result, there is no need to submit a notification of vehicle modification, and when no longer needed, the vehicle can be completely restored to its original state and used by attaching the tailgate 7, etc. In addition, since the upper member 110 and the lower member 130, 110, 130, are connected to each other while the flat plate-shaped upper base 111 and lower base 131 are stacked on the loading platform 9, the box body 6 can be stably attached to the loading platform 9 while maintaining the members 110, 130 in a stable position.

[0035] In this embodiment, an external thread is provided on the outer periphery of the protruding portion 115, and the connecting member 150 is a wing nut that can be screwed onto the external thread, so that the box body 6 can be attached to the loading platform 9 in a manner that allows easy attachment and detachment without the need for special tools. However, the connecting member 150 is not limited to this, and for example, if a hexagonal nut is firmly tightened with a wrench or the like, the attachment stability can be improved. Similarly, a hexagonal bolt or the like may be used as the fixing member 650 instead of a wing bolt. In addition, the protruding portion 115 and the connecting insertion hole 135 may be provided on either the upper base 111 or the lower base 131, but in this embodiment, the protruding portion 115 is provided on the upper base 111, and the connecting insertion hole 135 is provided on the lower base 131, so that the lower base 131 overlaps above the upper base 111. This is preferable because when a force is applied that tends to lift the box body 6 upward, the force can be resisted by the entire lower base 131 overlapping the upper base 111. Furthermore, in this embodiment, the lower member 130 is connected in a position in which the side surface portion 132 is aligned with the side surface of the loading platform 9, so that the mounting fixture 101 is less likely to shift position relative to the loading platform 9.

[0036] Furthermore, the mounting structure 100 of this embodiment is a mounting structure 100 for mounting a box body 6 to a loading platform 9 of a light truck 1 having at least one female hinge 11 for mounting a tailgate 7 provided on its left side (one side), and is provided with a side groove 610 that opens to the left side and extends along the left side when the box body 6 is loaded on the loading platform 9, at least one sliding member 630 slidably fitted into the side groove 610, and at least one mounting device 101, and is configured such that the fixing portion 113 is fixed to the sliding member 630, the sliding member 630 is slid within the side groove 610 and aligned to a predetermined position relative to the female hinge 11, and the box body 6 is mounted to the loading platform 9.

[0037] The position where the female hinge for attaching the tailgate plate is provided varies depending on the type of truck, etc. According to the configuration of the present embodiment described above, the fixing position of the upper member 110 can be easily adjusted to match the position of the lower member 130 pivotally supported by the female hinge 11 by the sliding member 630 sliding in the side groove 610 provided on the side of the box body 6. As a result, the same box body 6 can be loaded and attached as it is to various trucks having different female hinge arrangement positions. In addition, in many trucks, multiple female hinges 11 are provided on one side (for example, the left side) of the loading platform 9, but if multiple sliding members 630 are fitted into the side groove 610, it becomes possible to attach the box body 6 using an appropriate number and position of female hinges 11 according to the structure of the loading platform 9 and as necessary taking into consideration the dimensions, shape, and weight of the box body 6.

[0038] In addition, in the mounting structure 100 of this embodiment, the female hinge 11 includes a first female hinge 11A and a second female hinge 11B that are provided along the left side portion (one side portion) with a gap between them, and each of the first female hinge 11A and the second female hinge 11B has a through shaft hole 13 passing through the first female hinge 11A and the second female hinge 11B, the sliding member 630 includes a first sliding member 630A that is aligned at a predetermined position with respect to the first female hinge 11A, and a second sliding member 630B that is aligned at a predetermined position with respect to the second female hinge 11B, the mounting fixture 101 includes a first mounting fixture 101A and a second mounting fixture 101B, and the first mounting fixture 101 includes a second mounting fixture 101B. The upper member 110A of the second mounting fixture 101A is fixed to the first sliding member 630A at the fixing portion 113, the upper member 110B of the second mounting fixture 101B is fixed to the second sliding member 630B at the fixing portion 113, the lower member 130A of the first mounting fixture 101A is supported by inserting the shaft portion 133A into the through shaft hole 13 of the first female hinge 11A from a first direction D1, and the lower member 130B of the second mounting fixture 101B is supported by inserting the shaft portion 133B into the through shaft hole 13 of the second female hinge 11B from a second direction D2 directly opposite the first direction D1.

[0039] According to the configuration of the present embodiment, the movement of the box body 6 attached to the loading platform 9 in both directions along one side where the multiple female hinges 11A and 11B are provided is restricted. That is, the movement of the box body 6 in the first direction D1 is restricted by the first mounting fixture 101A pivotally supported by the first female hinge 11A, and the movement of the box body 6 in the second direction D2 is restricted by the second mounting fixture 101B pivotally supported by the second female hinge 11B. As a result, the movement of the box body 6 in both directions D1 and D2 along the axial direction of the hinges is restricted, and it becomes possible to attach the box body 6 to the loading platform 9 so as to be immovable relative to the loading platform 9 without requiring another movement restriction structure such as the retaining bolt 3 in the existing structure.
