[0003] [Patent Document 1] Patent Publication No. 2021-172187 Summary of the Invention [Problem to be solved by the invention]

[0004] Such a side guard includes a plurality of support members and guard members supported by the plurality of support members. The plurality of support members are aligned in the vehicle length direction, and each support member extends outward in the vehicle width direction and curves midway to form a generally L-shape extending downward, with the portions of each support member extending in the vehicle width direction connected to different horizontal joists of the loading platform, and the portions of each support member extending in the vehicle height direction connected to the guard members.

[0005] Since multiple horizontal joists are arranged in the vehicle length direction and multiple support members are connected to different horizontal joists, the positions of the support members in the vehicle length direction depend on the positions of the horizontal joists in the vehicle length direction.

[0006] Therefore, when adjusting the position of the support member in the vehicle length direction, it is necessary to also adjust the position of the horizontal joists in the vehicle length direction, which is very time-consuming.

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a side guard in which the position of the support portion that supports the guard portion can be easily adjusted in the vehicle length direction. [Means for solving the problem]

[0008] The present invention has been made to solve at least some of the above-mentioned problems, and can be realized as the following aspects or application examples.

[0009] The side guard according to this application example is a side guard provided on a vehicle having a plurality of horizontal joists arranged in the vehicle length direction on a frame and each extending in the vehicle width direction, and comprises a rail portion extending in the vehicle length direction and connected to the different horizontal joists, a guard portion extending in the vehicle length direction below the rail portion, and a support portion having at one end a first fixing portion whose movement is guided by the rail portion and which can be fixed at any position in the vehicle length direction of the rail portion, and at the other end a second fixing portion whose movement is guided by the guard portion and which can be fixed at any position in the vehicle length direction of the guard portion.

[0010] In the side guard according to this application example, the position of the support portion that supports the guard portion can be adjusted in the vehicle length direction without adjusting the position of the horizontal joist. In other words, according to the side guard according to this application example, the position of the support portion that supports the guard portion can be easily adjusted in the vehicle length direction. [Brief explanation of the drawings]

Figure 3 is a schematic left side view showing a part of the configuration of the vehicle 1 and the side guard 50 of this embodiment. Figure 4 is an AA cross-sectional view of the vehicle 1 shown in Figure 2. Note that the rear shaft 20, rear wheel 22, etc. are not shown in Figure 4.

[0013] Furthermore, the vehicle length direction of the vehicle 1 may be referred to as the X direction or the front-to-rear direction (see FIG. 1, etc.). The vehicle width direction of the vehicle 1 may be referred to as the Y direction or the left-to-right direction (see FIG. 2, etc.). Furthermore, the vehicle height direction of the vehicle 1 may be referred to as the Z direction, the up-down direction, or the vertical direction (see FIG. 1).

[0014] The vehicle 1 is, for example, a large automobile such as a truck, and includes a frame 10. The frame 10 is a chassis frame with a ladder frame structure, and includes a pair of left and right side rails 12, a plurality of cross members 14, and the like.

[0015] The pair of left and right side rails 12 includes a left side rail 12L and a right side rail 12R. The left side rail 12L and the right side rail 12R extend in the vehicle length direction. The left side rail 12L and the right side rail 12R are parallel to each other and spaced apart from each other in the vehicle width direction.

[0016] The cross member 14 extends in the vehicle width direction and connects the left side rail 12L and the right side rail 12R. The cross member 14 connects, for example, the front ends, the middle position, or the rear ends of the left side rail 12L and the right side rail 12R.

[0017] A pair of left and right front wheels 18 are suspended in front of the frame 10 via front shafts 16 and the like. The front wheels 18 include a left front wheel 18L and a right front wheel 18R. A pair of left and right rear wheels 22 are suspended in rear of the frame 10 via rear shafts 20 and the like. The rear wheels 22 include a left rear wheel 22L and a right rear wheel 22R.

[0018] In addition to the frame 10, the vehicle 1 also includes a cabin (cab) 30 and a loading platform (body) 40. The cabin 30 is mounted on the frame 10 at the front of the vehicle 1, and seats and the like are provided inside.

[0019] The cargo bed 40 is mounted on the frame 10 behind the cabin 30. The cargo bed 40 includes a pair of left and right vertical joists 42, a plurality of horizontal joists 44, a floor panel 46, and the like. Although not shown, the cargo bed 40 also includes parts in addition to the floor panel 46, etc., depending on the type of cargo bed 40. For example, if the cargo bed 40 is configured as a van body, the cargo bed 40 also includes a pair of left and right side panels, a front panel, a ceiling panel, opening and closing doors, and the like.

[0020] The pair of left and right vertical joists 42 includes a left vertical joist 42L and a right vertical joist 42R. The left vertical joist 42L and the right vertical joist 42R are square timbers extending in the vehicle length direction, and are provided on different side rails 12 behind the cabin 30. Specifically, the left vertical joist 42L is provided on the left side rail 12L behind the cabin 30, and the right vertical joist 42R is provided on the right side rail 12R behind the cabin 30.

[0021] The horizontal joists 44 are square timbers that extend in the vehicle width direction, straddling the pair of left and right vertical joists 42, and are provided on the pair of left and right vertical joists 42 behind the cabin 30. The multiple horizontal joists 44 are arranged in the vehicle length direction on the pair of left and right vertical joists 42. The multiple horizontal joists 44 include a first horizontal joist 44a, a second horizontal joist 44b, a third horizontal joist 44c, a fourth horizontal joist 44d, and a fifth horizontal joist 44e.

[0022] The floor panel 46 is a flat panel. The floor panel 46 is provided on the horizontal joists 44 at the rear of the cabin 30, thereby covering the horizontal joists 44.

[0023] In addition to the cargo bed 40, the vehicle 1 also has side guards 50. The side guards 50 are arranged on the outer sides of the frame 10 in the vehicle width direction to prevent pedestrians and the like from being caught in the side guards. The side guards 50 include a rail portion 52, a guard portion 54, and a plurality of support portions 56.

[0024] The rail portion 52 is a shaft member extending in the vehicle length direction, and is connected at least at two or more points (for example, both ends) to different horizontal joists 44. Specifically, the rail portion 52 is a cylindrical member extending in the vehicle length direction, and is inserted through the second horizontal joist 44b and the third horizontal joist 44c, with one end connected to the first horizontal joist 44a and the other end connected to the fourth horizontal joist 44d.

[0025] The guard portion 54 is a shaft member that extends in the vehicle length direction below the rail portion 52, and both ends are curved toward the inside in the vehicle width direction. Specifically, the guard portion 54 is a cylindrical member that extends in the vehicle length direction below and outside the rail portion 52 in the vehicle width direction.

[0026] The support portion 56 is a shaft member extending from the rail portion 52 toward the guard portion 54. Specifically, the support portion 56 is a plate-like member that extends in the vehicle height direction and is bent in the vehicle width direction, and extends from the rail portion 52 toward the guard portion 54.

[0027] The support portion 56 has a first fixing portion 58 at one end. The first fixing portion 58 of the support portion 56 is located near the circumferential surface of the rail portion 52 and faces the circumferential surface of the rail portion 52. Specifically, the first fixing portion 58 of the support portion 56 is located near the circumferential surface of the rail portion 52 between the horizontal joists 44 adjacent to the first fixing portion 58 in the vehicle length direction and faces the circumferential surface of the rail portion 52.

[0028] The support portion 56 also has at its other end a second fixing portion 60. The second fixing portion 60 of the support portion 56 is located near the circumferential surface of the guard portion 54 and faces the circumferential surface of the guard portion 54.

[0029] The side guard 50 includes a plurality of first fasteners 62 and a plurality of second fasteners 68 in addition to the support portion 56 and the like.

[0030] The first fixture 62 includes a first guide member 64 and a first position fixing member 66 , and the second fixture 68 includes a second guide member 70 and a second position fixing member 72 .

[0031] The first guide member 64 and the second guide member 70 are, for example, U-bolts, and are members that are bent, curved, or a combination thereof to form a folded shape (for example, a C-shape, U-shape, or trapezoidal shape) with both ends facing each other.

[0032] The first guide member 64 is hooked onto the circumferential surface of the rail portion 52, and the rail portion 52 is interposed between both ends of the first guide member 64.

[0033] The first guide member 64 is attached to the first fixed portion 58 of the support portion 56 in a state where it is hooked onto the peripheral surface of the rail portion 52. The first guide member 64 is attached to the first fixed portion 58 by inserting both ends of the first guide member 64 into openings (not shown) of the first fixed portion 58.

[0034] The first position fixing members 66 are, for example, nuts, and are attached to both ends of the first guide member 64 on the side opposite the rail portion 52 side of the first fixing portion 58, preventing the first guide member 64 from falling off the first fixing portion 58. The first position fixing members 66 also adjust the degree to which the rail portion 52 is clamped between the first fixing portion 58 of the support portion 56 and the first guide member 64.

[0035] The first position fixing member 66 allows the first guide member 64 to be switched between a loosely fitted state in which it is not fixed to the circumferential surface of the rail portion 52, and a fixed state in which it is fixed to the circumferential surface of the rail portion 52.

[0036] The second guide member 70 is hooked onto the circumferential surface of the guard portion 54, and the guard portion 54 is interposed between both ends of the second guide member 70.

[0037] The second guide member 70 is attached to the second fixing portion 60 of the support portion 56 in a state where it is hooked onto the peripheral surface of the guard portion 54. The second guide member 70 is attached to the second fixing portion 60 by inserting both ends of the second guide member 70 into openings (not shown) of the second fixing portion 60.

[0038] The second position fixing members 72 are attached to both ends of the second guide member 70 on the side of the second fixing part 60 opposite the guard part 54 side, and prevent the second guide member 70 from falling off the second fixing part 60. The second position fixing members 72 also adjust the degree to which the guard part 54 is clamped between the second fixing part 60 of the support part 56 and the second guide member 70.

[0039] The second position fixing member 72 allows the second guide member 70 to be switched between a loosely fitted state in which it is not fixed to the circumferential surface of the guard portion 54 and a fixed state in which it is fixed to the circumferential surface of the guard portion 54.

[0040] In the side guard 50, when the first guide member 64 and the second guide member 70 are both loosely fitted, the support portion 56 can move in the vehicle length direction. The range of movement of the support portion 56 in the vehicle length direction is the same as the distance between the horizontal joists 44 adjacent to the first fixed portion 58 in the vehicle length direction.

[0041] Furthermore, when the first guide member 64 and the second guide member 70 are both loosely fitted, the movement of the first guide member 64 is guided by the rail portion 52, and the movement of the second guide member 70 is guided by the guard portion 54. Since the first guide member 64 is attached to the first fixed portion 58 of the support portion 56, and the second guide member 70 is attached to the second fixed portion 60 of the support portion 56, when the first guide member 64 and the second guide member 70 are both loosely fitted, the movement of the first fixed portion 58 of the support portion 56 is guided by the rail portion 52, and the movement of the second fixed portion 60 of the support portion 56 is guided by the guard portion 54.

[0042] Furthermore, in the side guard 50, by switching the first guide member 64 from a loosely fitted state to a fixed state, it is possible to fix the first fixing portion 58 at any position in the vehicle length direction of the rail portion 52. Specifically, in the side guard 50, by switching the first guide member 64 from a loosely fitted state to a fixed state, it is possible to fix the first fixing portion 58 at any position in the vehicle length direction of the rail portion 52 between the horizontal joists 44 adjacent to the first fixing portion 58 in the vehicle length direction.

[0043] Furthermore, in the side guard 50, by switching the second guide member 70 from a loosely fitted state to a fixed state, it is possible to fix the second fixing portion 60 at any position in the vehicle length direction of the guard portion 54. Specifically, in the side guard 50, by switching the second guide member 70 from a loosely fitted state to a fixed state, it is possible to fix the second fixing portion 60 at any position in the vehicle length direction of the guard portion 54 within the movement range of the support portion 56.

[0044] For these reasons, the first fixing portion 58 of the support portion 56 is guided in its movement by the rail portion 52 and can be fixed at any position on the rail portion 52 in the vehicle length direction, and the second fixing portion 60 of the support portion 56 is guided in its movement by the guard portion 54 and can be fixed at any position on the guard portion 54 in the vehicle length direction.

[0045] With this type of side guard 50, the position of the support portion 56 that supports the guard portion 54 can be adjusted in the vehicle length direction without having to adjust the position of the horizontal joist 44. In other words, with this type of side guard 50, the position of the support portion 56 that supports the guard portion 54 can be easily adjusted in the vehicle length direction.

[0046] This concludes the description of the embodiment of the present invention, but the specific configuration shown in this embodiment is just an example, and the aspects of the present invention are not limited to the configuration shown in this embodiment.

[0047] The side guard 50 of the above embodiment may include one or more rail portions 52. If the side guard 50 includes multiple rail portions 52, the multiple rail portions 52 are aligned in the vehicle length direction. In this case, the multiple rail portions 52 are preferably aligned in the same straight line.

[0048] In the above embodiment, when the end of the rail portion 52 is not connected to the horizontal joist 44, i.e., when the rail portion 52 is connected to the horizontal joist 44 at a midpoint in the vehicle length direction, the first fixing portion 58 of the support portion 56 may be positioned near the circumferential surface of the rail portion 52, between the end of the rail portion 52 adjacent to the first fixing portion 58 in the vehicle length direction and the horizontal joist 44.

[0049] In addition, when the first fixed portion 58 of the support portion 56 is located near the circumferential surface of the rail portion 52, between the end of the rail portion 52 adjacent to the first fixed portion 58 in the vehicle length direction and the horizontal joist 44, the range of movement of the support portion 56 in the vehicle length direction is the same as the distance between the end of the rail portion 52 adjacent to the first fixed portion 58 in the vehicle length direction and the horizontal joist 44.

[0050] Furthermore, when the first fixing portion 58 of the support portion 56 is positioned near the circumferential surface of the rail portion 52 between the end of the rail portion 52 adjacent to the first fixing portion 58 in the vehicle length direction and the horizontal joist 44, the first fixing portion 58 can be fixed at any position in the vehicle length direction of the rail portion 52 between them.

[0051] In the above embodiment, as long as the support portion 56 can be moved in the vehicle length direction as described above, the shapes of the various components included in the side guard 50 are not particularly limited. For example, the rail portion 52 and the guard portion 54 may be rectangular tubular. [Explanation of symbols]
