【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 5, the opening / closing body is a tailgate 11 in this example, and the tailgate 11 is provided at the rear end of the loading platform 12 of the truck 10. The left end of the tailgate 11 is attached to the left gate support 13 of the luggage carrier 12 by the hinge device 16 shown in FIG. 1, and the right end of the tailgate 11 is located on the right side of the luggage carrier 12 by the hinge means 21 shown in FIG. It is attached to the gate support portion 14.

The hinge device 16 includes a hinge mail 17 protruding from the lower portion of the inner surface of the left gate support portion 13 in the vehicle width direction and fixed to the gate support portion 13, and the left side of the tailgate 11 facing the hinge mail 17. A hinge female 18 protruding from the lower part of the surface in the vehicle width direction and rotatably attached to the tailgate 11 is provided (FIGS. 1 and 3). The hinge mail 17 has a mail main body 17a formed in a shaft shape and a bracket 17b holding the mail main body 17a (FIGS. 1 and 3). The outer peripheral surface of the mail body 17a is composed of two planes 17c, 17c parallel to each other and two arcuate peripheral surfaces 17d, 17d connected to them (Fig. 4). The mail main body 17a is welded to the bracket 17b such that the upper arc-shaped peripheral surface 17d is located behind the loading platform 12 by θ (FIG. 4) from the vertical direction about the axis of the hinge mail 17 as a center. 17b is fixed to the left gate support portion 13 by a bolt 19 (FIGS. 1 and 3).

The hinge female 18 has a female main body 18a that can be fitted into the male main body 17a, a shaft 18b welded to the female main body 18a, and a bracket 18c that rotatably holds the shaft 18b (FIG. 1 and FIG. 1). (Figure 3). In the main body 18a of the file, the direction substantially perpendicular to the axis of the hinge mail 17 and substantially parallel to the two planes 17c, 17c, that is, about the axis of the hinge mail 17 and θ from the vertical direction, is behind the platform 12. A concave portion 18d that can be inserted into or removed from the mail main body 17a from a direction inclining to is formed. The width of the recess 18d is formed slightly wider than the width between the two flat surfaces 17c, 17c (FIGS. 1 and 4). The shaft 18b into which the first resin collar 18e and the disc spring 18f are fitted is inserted into a through hole 18h formed in the bracket 18c via a second resin color 18g. A stop ring 18j for retaining is fitted to the shaft 18b inserted through the through hole 18h via a third resin collar 18i. The bracket 18c is fixed to the lower portion of the left side surface of the tail gate 11 with a bolt 19 (FIG. 3). The first resin collar 18e, the second resin collar 18g, and the third resin collar 18i are slide bearings, and may be formed of sintered metal or the like.

The hinge means 21 is a protrusion member 22 that is fixed to the gate support portion 14 by protruding from the lower portion of the inner surface of the right side gate support portion 14 in the vehicle width direction, and a tailgate that faces the protrusion member 22. The tubular member 23 is fixed to the tailgate 11 so as to project from the lower portion of the right side surface of the vehicle 11 in the vehicle width direction. The protrusion member 22 has a protrusion main body 22a formed in a cylindrical shaft shape and a bracket 22b to which the protrusion main body 22a is welded. The bracket 22b is fixed to the gate support portion 14 on the right side by a bolt 24. It The tubular member 23 has a tubular body 23a that can be fitted into the protrusion body 22a from the axial direction thereof, and a bracket 23b to which the tubular body 23a is welded. The bracket 23b is attached to the lower right side of the tailgate 11 by a bolt 24. (Fig. 2). The cylinder main body 23a fitted in the projection main body 22a is adapted to rotate as the tail gate 11 is opened and closed.

The operation of the hinge device for the vehicle opening / closing body configured as described above will be described. When the tailgate 11 is attached to the gate support portions 13 and 14 of the luggage carrier 12 of the truck 10, first, the tube main body 23a of the tailgate 11 is fitted into the protrusion main body 22a of the right gate support portion 14. Next, the female body 18a of the tailgate 11 is rotated so that the opening of the recess 18d faces the upper arcuate peripheral surface 17d of the mail body 17a. In this state, the female body 18a is substantially perpendicular to the axis of the hinge mail 17. The recess 18d of the female main body 18a is fitted into the main mail body 17a in a direction substantially parallel to the two planes 17c, 17c, that is, in a direction inclining from the vertical direction to the rear of the loading platform 12 about the axis of the hinge mail 17 by θ. When the tailgate 11 is opened and closed in this state, the barrel main body 23a rotates about the protrusion main body 22a as a spindle, but the female main body 18a rotates because it is locked to the mail main body 17a fixed to the gate support portion 13. do not do. As a result, the tailgate 11 does not fall off regardless of the opening angle of the tailgate 11. When detaching the tailgate 11 from the gate support portions 13 and 14, first, the left side of the tailgate 11 is pulled up in a direction inclining to the rear of the loading platform 12 by θ from the vertical direction about the axis of the hinge mail 17 as a center. After the main body 18a is separated from the mail main body 17a, the tailgate 11 is displaced leftward to separate the cylinder main body 23a from the protrusion main body 22a. As a result, the tailgate 11 can be attached to and detached from the gate support portions 13 and 14 regardless of the opening angle of the tailgate 11, so that even if an obstacle is present near the rear of the luggage platform 12, The tailgate 11 can be easily attached and detached.

In the above embodiment, the tailgate of the truck is used as the opening / closing member, but this is only an example and may be a back door of a cover-top type vehicle, a van type vehicle, or other vehicles. In this case, the back door is provided at the rear end of the luggage compartment. Further, in the above embodiment, only the left end of the tailgate is attached to the left side gate support by the hinge device of the present invention, but not limited to this, the right end of the tailgate is also attached to the right gate support by the hinge device of the present invention. May be attached to. Further, although not shown, the hinge mail is rotatably attached to one or both of the both ends of the opening / closing body 11, and the hinge mail is supported by tilting the concave portion upward by the angle θ in FIG. Even if it is fixed to either one or both of the parts 13 and 14, the same action and effect as in the embodiment can be obtained.

[0013]

[Effect of device]

 As described above, according to the present invention, the hinge mail is formed in the shape of an axis having two planes parallel to each other, and the hinge mail is substantially perpendicular to the axis of the hinge mail, and the two planes are substantially parallel to each other. Since a recess that can be inserted into or removed from the hinge mail from the parallel direction is formed, the hinge mail or hinge female is fixed to the opening / closing body support part, and the hinge female or hinge mail is rotatably attached to the end of the opening / closing body. The opening / closing body can be attached / detached to / from the opening / closing body support portion regardless of the opening angle of the body. As a result, the opening / closing body can be easily attached / detached even when an obstacle is present close to the rear of the loading platform or in a fully opened state.
