(Embodiment) An embodiment of the present invention will be specifically described below with reference to FIGS. The present embodiment is applied to a tire carrier 3 mounted on a vehicle body rear portion 2 of a vehicle having a flip-up type back door 1 as shown in FIG. The tire carrier 3 is mainly composed of a support frame 4 formed by bending a pipe material into a substantially U-shape, and an appropriate number of bolts 5 for mounting a tire are provided at the center of the support frame 4. A tire cradle 6 is provided. The upper and lower ends of the support frame 4 of the tire carrier 3 are horizontally rotatably attached to one side of the vehicle body rear portion 2.

That is, as well shown in FIGS. 1 to 4, a hinge body 7 formed in a U shape is fixed to the vehicle body side, and the support frame 4 which is a movable member is fixed to the hinge body 7.
One end of is attached so as to be horizontally rotatable via a hinge pin 8 to form a hinge mechanism. The tire carrier 3 is always held by a locking device (not shown) in a state where the support frame 4 is positioned on the rear part 2 side of the vehicle body in a state substantially parallel to the rear surface as shown by the solid line in FIG. There is.

Next, regarding opening and closing of the back door 1, a hinge stopper 9 provided in a hinge mechanism of the tire carrier 3 so as to stop the tire carrier 3 which is rotated rearward as shown by an imaginary line in FIG. explain. As shown in FIGS. 1 to 4, a vertical through hole 10 is formed in each of the upper and lower flanges 7a of the U-shaped hinge body 7 near the web 7b. An operating rod 11, which is a stopper operating member, penetrates through 10 so that push-pull operation can be performed. The operation rod 11 has a diameter slightly smaller than that of the through hole 10, has an operation knob 12 at the upper end, and integrally has a stopper piece 13 as a lower stopper member on the lower side. . And this stopper piece 13
Can be moved in and out of the recess 14 formed on the inner surface side of the lower flange 7a by pushing and pulling the operating rod 11.

That is, the lower stopper piece 14 is inserted into the recess 14 when the operation rod 11 is pushed down,
When the pulling operation of 11 is performed, the support frame 4 is protruded from the recess 14
It can be engaged with the lower portion of the outer peripheral surface of the boss portion 4a.

On the other hand, the upper flange 7a of the hinge body 7 has a circular vertical hole.
15 is formed, and a stopper pin 16 which is an upper stopper member is fitted in the vertical hole 15 so as to be able to move in and out. The stopper pin 16 is connected to the operation rod 11 via a link 17 so as to interlock with the operation rod 11. That is, the link 17 for interlocking is accommodated in the recess 18 formed on the inner surface side of the upper flange 7a, and its substantially central portion is rotatably attached to the bracket 19 via the center pin 20, and One end is connected to the stopper pin 16 by the pin 21, and the other end is connected to the operation rod 11 by the pin 22.

Thus, the upper stopper pin 16 is inserted into the vertical hole 15 when the operation rod 11 is pushed down, but protrudes from the vertical hole 15 when the operation rod 11 is pulled up and protrudes from the outer peripheral surface of the boss portion 4a of the support frame 4. It can be engaged with the upper part.

Further, an O-ring 23, which is a means for holding the operating rod 11 at a pulling position, is provided above and below the operating rod 11, and the O-ring 23 is elastic in the through hole 10 when the operating rod 11 is pulled up. By fitting, the operation rod 11 is held at the same operation position. Further, a taper flange portion 11a is formed at the lower end of the operation rod 11, and the taper flange portion 11a is fitted with the taper large diameter hole 10a of the through hole 10 of the lower flange 7a when the operation rod 11 is pulled up. The movement of the operating rod 11 is restricted.

The hinge stopper 9 of this embodiment is configured as described above, and the operation rod 11 is normally pushed down at a position where the tire carrier 3 is locked to the vehicle body rear portion 2 side, and the stopper piece 13 and the stopper are provided. As shown in FIGS. 1 and 3, the pin 16 is retracted to a position retracted from the inner surface of the flange 7a of the hinge body 7, that is, a position allowing the support frame 4 of the tire carrier 3 to rotate. .

In such a state, when the back door 1 is opened and closed, the tire carrier 3 is unlocked with respect to the rear part 2 of the vehicle body, and then the tire carrier 3 is rotated rearward as shown by an imaginary line in FIG. In addition, this rear rotation end is
For example, it can be regulated by an end stopper (not shown). After that, when the operation knob 11 is grasped and the operation rod 11 is pulled up, a stopper piece integrated with the operation rod 11 is formed.
13 protrudes upward from the recess 14, and the stopper pin 16 that interlocks via the link 17 protrudes downward from the vertical hole 15. That is, as shown in FIGS. 1 and 3, the stopper piece 13 and the stopper pin 16 are displaced to positions that prevent rotation of the support frame 4 and engage with the upper and lower outer peripheral portions of the boss portion 4a of the support frame 4, respectively. By doing so, it is possible to prevent the support frame 4 from rotating forward to the original position. Further, this rotation-prevented state can be continuously maintained by elastically fitting the O-ring 23 of the operation rod 11 into the through hole 10.

It should be noted that although the present invention has been illustrated and described with respect to a preferred embodiment, various changes are possible within the scope without departing from the spirit of the present invention, for example, as a means for holding the operating rod 11 in the pulling position. , Change to O-ring 23,
The operation knob 12 with the tongue piece can be rotatably attached to the operation rod 11, and the tongue piece can be held by being locked by the platform formed on the upper flange 7a. Further, in the illustrated example, the case of horizontally rotating is also possible, but it is also possible to implement a hinge mechanism that rotates in the vertical direction, and the application site is not limited to the tire carrier 3, and it is necessary to stop at the rotating end. Any hinge mechanism can be applied.

(Effect of the Invention) As described in detail above, the hinge stopper of the present invention can stop or release the movable member of the hinge mechanism to the rotating position by simply pushing and pulling the operating member. The operation is much simpler than the pull-out / plug-in method. Further, the coat does not sway and looks good, and the stopper member is not lost. Furthermore, in the present invention, the stopper member is composed of a stopper piece fixed to the stopper operating member, and a stopper pin connected to the stopper operating member via a link and displaceable in directions opposite to the stopper piece. With this, since the stopper piece and the stopper pin can be engaged with the movable member on both sides in the axial direction of the rotation center of the movable member by an operation by one operation member, the rotation can be prevented, so that the movable member has a simple structure. A strong and reliable stopper function can be obtained against an external force that attempts to rotate the, and it can be applied to, for example, a heavy door. Further, according to the present invention,
In the state where the stopper member is displaced to the retracted position, the stopper member does not make frictional contact with the movable member, so that it does not act as an operation resistance of the movable member and does not cause abnormal noise.
