The component 34 is attached to the loading platform 20 side.

  Any one of the plurality of hinges 30 provided along the side-side tilt plate 22 functions as a stopper hinge 36 having a drop-off preventing function for preventing the side-side tilt plate 22 from sliding backward and preventing the drop-off. Is. In the present embodiment, the hinge 30 provided at the position closest to the vehicle body front side with respect to the side-side tilt plate 22 functions as the stopper hinge 36. Further, the hinges 30 other than those functioning as the stopper hinges 36 function as rear-extracting hinges 38 attached so as to allow the side-side tilt plate 22 to slide backward. In other words, the hinge 30 that functions as the post-extracting hinge 38 does not have a drop-off preventing function, and is provided mainly for supporting the side-side tilt plate 22.

  The male hinge 40 constituting the hinge 30 described above includes a pin 42 and a male side fixing portion 44. Specifically, the male hinge 40 has a cylindrical holding portion 46 formed by bending an end portion of a metal plate into a cylindrical shape, and the pin 42 is held by the holding portion 46. Projects in the longitudinal direction. Further, in the plate body forming the male hinge 40, a fixing tool such as a weld or a bolt is attached to the vehicle body of the track T or the side-side tilt plate 22 on a flat portion opposite to the pin 42 being fixed. A male side fixing portion 44 is provided so that it can be fixed by using.

  The female hinge 50 includes a receiving portion 52 (rear receiving portion) and a female side fixing portion 54. Specifically, the female hinge 50 is formed by processing a metal plate having a substantially “L” shape in plan view. In other words, the male hinge 50 is obtained by bending a plate body provided with a notch 56 at one corner of a rectangular metal plate. The length of the notch 56 is approximately equal to or slightly larger than the length of the holding portion 46 of the male hinge 40 described above.

  The female hinge 50 is a portion of the substantially “L” -shaped metal plate that is short in the longitudinal direction of the hinge 30 (the vehicle longitudinal direction in the attached state), that is, a portion that is adjacent to the notch 56 in the longitudinal direction. Has a receiving portion 52 formed by bending the tube into a cylindrical shape. The receiving portion 52 is a portion that pivotally supports the pin 42 so that the pin 42 can be inserted and removed, and has an inner diameter substantially equal to or slightly larger than the pin 42 included in the male hinge 40 described above. Further, the female side fixing portion 54 is formed in a portion where the length in the longitudinal direction of the hinge 30 existing on the opposite side to the receiving portion 52 in the plate body forming the female hinge 50 is formed.

  In the present embodiment, of the plurality of hinges 30, the female side fixing portion 54 that functions as the stopper hinge 36 has two holes 58 in the longitudinal direction of the hinge 30 for inserting the bolts 60 that are the fixing tools. It is supposed to have. Further, the female side fixing portion 54 of the hinge 30 that functions as the post-extracting hinge 38 is fixed by welding, and therefore does not include the hole 58.

  The hinge 30 is brought into a connected state by placing the holding portion 46 of the male hinge 40 in the cutout portion 56 of the female hinge 50 and inserting the pin 42 into the receiving portion 52 of the female hinge 50. Thereby, it will be in the state which can be rotated centering on the pin 42. FIG. Further, the hinge 30 can be disassembled by relatively separating the male hinge 40 and the female hinge 50 along the pin 42.

  In the tilting plate mounting structure 10, among the plurality of hinges 30, 30 that fix the side tilting plates 22, 22 provided on both sides, the one that is mounted on the frontmost side of the vehicle body is the stopper hinges 36, 36. Installed to function. Further, the hinges 30 and 30 other than those that function as the stopper hinges 36 and 36 are attached so as to function as the post-extracting hinges 38 and 38.

  Specifically, what functions as the stopper hinges 36, 36 is the male hinge 40 attached to the side-side tilt plates 22, 22, which is attached to either the left or right side-side tilt plates 22, 22. 40 is attached so that it may become the front with respect to the female hinges 50 and 50 attached to the vehicle body side (loading platform 20 side). Therefore, the receiving portion 52 (rear receiving portion) of the female hinge 50 exists at a position adjacent to the holding portion 46 of the male hinge 40 on the rear side in the axial direction. The female hinges 50, 50 that form the stopper hinges 36, 36 are fixed to the vehicle body side by bolts 60, 60 attached through holes 58, 58.

  On the other hand, of the hinges 30, 30 attached to the left and right side-side tilt plates 22, 22, those that function as the rear extraction hinges 38, 38 are those that function as the stopper hinges 36, 36 and male hinges 40, 40. And the front-rear relationship of the female hinges 50, 50 is reversed. That is, the hinges 30, 30 functioning as the rear extraction hinges 38, 38 are attached so that the male hinges 40, 40 are located rearward with respect to the female hinges 50, 50.

  As described above, the hinge 30 constituting the tilt plate mounting structure 10 can be either an insertion / removal hinge that can be integrated or disassembled by moving the male hinge 40 and the female hinge 50 relative to each other along the pin 42. It is supposed to be similar to this. Although the rear extraction hinge 38 can be disassembled by sliding the side-side tilt plate 22 toward the rear side of the vehicle body, the stopper hinge 36 only slides the side-side tilt plate 22 toward the rear side of the vehicle body. It cannot be disassembled. That is, in the stopper hinge 36, the arrangement of the male hinge 40 and the female hinge 50 is opposite to that of the rear extraction hinge 38, and unless the bolt 60 is removed, the receiving portion 52 (rear receiving portion) of the female hinge 50 is The movement of the holding part 46 of the male hinge 40 is obstructed, and the female hinge 50 cannot be removed. Therefore, in the tilting plate mounting structure 10, the side tilting plate 22 provided on the loading platform 20 of the truck T is held so as not to drop off even when a shock from the front to the rear of the vehicle body is received due to a collision or the like. It becomes possible to do.

  In the tilt plate mounting structure 10 of the present embodiment, the side tilt plates 22 on both sides can be prevented from falling off by the hinges 30, 30 functioning as the stopper hinges 36, 36. Therefore, in the tilt plate mounting structure 10, there is no need to provide a retaining member as described in the prior art. Therefore, the tilt plate mounting structure 10 of the present embodiment can maintain the effects such as rust prevention without complicating the configuration.

  In the tilt plate mounting structure 10 of the present embodiment, the hinge 30 that functions as the stopper hinge 36 and the rear extraction hinge 38 on one side in the vehicle width direction can be used as the rear extraction hinge 38 and the stopper hinge 36 on the other side, respectively. it can. Accordingly, it is not necessary to separately prepare the hinges 30 and 30 which are different from each other for the side-side tilt plates 22 and 22 on one side and the other side in the vehicle body width direction. Therefore, by adopting the tilt plate mounting structure 10, it is possible to share parts in the left and right side tilt plates 22, 22 and reduce the manufacturing cost.

  As described above, in the track T of the present embodiment, the fixing structure for the rear end side tilt plate 24 also functions as the hinge 30 that functions as the stopper hinge 36 and the rear extraction hinge as in the tilt plate mounting structure 10. However, the present invention is not limited to this. That is, the rear end side tilt plate 24 may be attached by a conventionally known so-called insertion / extraction hinge or the like.

  Moreover, in this embodiment, although the structure which attached the side side edge board 22 and 22 of both sides with the edge board attachment structure 10 was illustrated, this invention is not limited to this, Only any one is demonstrated. It is good also as attaching with the tilting board attachment structure 10. FIG.

  In the present embodiment, an example is shown in which the hinges 30, 30 provided at the most vehicle front side positions on the side-side tilt plates 22, 22 are stopper hinges 36, 36 and the other are rear-extracted hinges 38, 38. However, the tilt plate mounting structure 10 of the present invention is not limited to this. That is, in the tilt plate mounting structure 10, the position and quantity of the stopper hinges 36 and 36 and the rear extraction hinges 38 and 38 can be appropriately changed. For example, the tilt plate mounting structure 10 may have a configuration in which the stopper hinges 36 and 36 are provided at a position closest to the vehicle rear side. In the tilt plate mounting structure 10, the stopper hinges 36 and 36 may be provided at two or more locations on the side tilt plates 22 and 22.

  In the present embodiment, the example in which the hinge 30 having the same configuration as the stopper hinges 36 and 36 is used as the rear extraction hinges 38 and 38 is shown. However, the present invention is not limited to this, and other than the hinge 30. These hinges may be used as the post-extracting hinge 38. Moreover, you may comprise by hinges other than what is called an insertion / extraction hinge instead of the rear extraction hinges 38 and 38. FIG.

  The shape and the like of each member constituting the tilt plate mounting structure 10 are not limited to those illustrated in the present embodiment, and can be changed as appropriate without departing from the spirit of the present invention. Specifically, in the present embodiment, an example in which the planar shape of the female hinge 50 is a substantially “L” shape is shown, but the present invention is not limited to this, and is similar to the male hinge 40. The planar shape may be a substantially rectangular shape. Further, the planar shape of the male hinge 40 may be an irregular shape such as a substantially “L” shape.

  Specifically, as shown in FIG. 5, the male hinge 40 is formed so that the pins 42 protrude from both ends of the holding portion 46, and the external shape of the female hinge 50 is substantially “C” -shaped. Similarly to 52, it is possible to adopt a configuration in which receiving portions 152, 152 capable of receiving the pin 42 are provided on both sides of the notch portion 56. The receiving portions 152 and 152 have a substantially “C” cross-sectional shape and are configured to be mounted so as to cover the pin 42 from above, so that the female hinge 50 can be attached and detached by attaching and detaching the bolt 60. Is possible. Of the two receiving portions 152, 152, the one that arrives on the vehicle rear side in the attached state is on the rear side in the axial direction with respect to the holding portion 46 of the male hinge 40 in the same manner as the receiving portion 52 described above. Arriving at an adjacent position, it can serve as a rear receiving part that prevents the male hinge 40 from falling off. Therefore, even when the hinge 30 functioning as the stopper hinge 36 is configured as shown in FIG. 5, it is possible to prevent the side-side tilt plate 22 from falling off due to an impact such as a collision.

  In the stopper hinge 36 exemplified in the present embodiment, the example in which the female hinge 50 is attachable and detachable by the bolt 60 and the male hinge 40 is attached so as not to be attachable and detachable by welding is shown, but the present invention is limited to this. It is not a thing. That is, the female hinge 50 may be fixed by welding or the like, and the male hinge 40 may be detachable using the bolt 60 or the like. Further, both the male hinge 40 and the female hinge 50 may be detachable using bolts 60 or the like.

  Further, in the present embodiment, the side plate side members 22, 32 attached to the side side plate 22, 22 side are the male hinges 40, 40, and the carrier side member 34, 34 attached to the carrier 20 side is the female hinge. Although the example of 50 and 50 is shown, the present invention is not limited to this, and may be reversed. In the case where the tilt plate side structural members 32, 32 are female hinges 50, 50 and the cargo bed side structural members 34, 34 are male hinges 40, 40, the female hinges 50, 50 that function as the stopper hinges 36, 36 are used. Needs to be attached to the male hinges 40, 40 so as to be on the front side of the vehicle.
