[0033]   Thus, the hinge mechanism having the above-described structure has the first structure as shown in FIGS. When the hinge base 100 is installed in the rear gate pillar 200 of the vehicle, the second hinge base 1 10 are inside the rear gate door 210, the first side plate portion 103 and the mounting flange, respectively. Using the mounting holes formed in the mounting holes 105, 106 and the mounting flanges 114 to 117. It can be attached with bolts.

[0034]   The state shown in the figure is on the left side of the vehicle, and the same on the right side. A structure is provided. However, the mechanism is left and right.

[0035]   When the rear gate door 210 shown in FIGS. 1 to 5 is fully closed, A plane including the axes of the first pivot 131 and the second pivot 132 is located at the most lateral side of the vehicle. In addition, the U-shaped hinge arm 120 when viewed from the axial direction is It is arranged so that it exists on the center side of the vehicle. At this time, the arc portion of the first cam 141 141C is on the center side of the vehicle, and the arc portion 142C of the second cam 142 is on the front side of the vehicle. The first lever 143 is arranged so as to face the arc portion 141C of the first cam 141. 143A of the cam follower comes into contact with the second cam 142, and the second lever 142 is attached to the inclined surface portion 142D of the second cam 142. -144 cam follower 144A is in contact.

[0036]   When the rear gate door 210 is opened from this state, first, it is opened up to 90 degrees. The door operation is as follows.

[0037]   That is, when the force for opening the door is exerted on the rear gate door 210, The fixed second hinge base 210 tries to rotate around the second pivot 132. However, as described above (see FIG. 4), the second cam fixed to the second hinge base 110 is provided. The inclined surface portion 142D of 142 is in contact with the cam follower 144A of the second lever 144. That is, even if an attempt is made to rotate the second lever 144 on the slope portion 142D, The lever 144 contacts the circular arc portion 141C of the first cam 141 and is in a non-rotatable state. The second lever 1 is connected to the first lever 143 with the link member 145. Since 44 is also in the non-rotatable state, it cannot rotate about the second pivot 132. is there. As a result, the rear gated around the first pivot 131 where no restraining force acts. A 210 rotates.

[0038]   That is, the relative relationship between the second hinge base 110 and the hinge arm 120 is not correct. While still in motion, the hinge arm 120, as shown in FIGS. Rotate around 1. As the hinge arm 120 rotates, it is supported by it. The first lever 143 that is rotating also rotates, but the cam fob of the first lever 143 rotates. The lower 143A only moves on the circular arc portion 141A having the same diameter of the first cam 141. . When the rear gate door 210 reaches the 90-degree open position, the first adjustment screw 18 The tip of No. 1 abuts on the second side plate portion 104 of the first hinge base 100, Further rotation of 120 is blocked (see Figure 9). And at the same time, the first lever The contact of the cam follower portion 143A with the circular arc portion 141A is released.

[0039]   Further, the operation of the check force applying mechanism during the door opening operation up to 90 degrees is shown in FIG. The description will be made with reference. As described above, the rear gate door 210 and the hinge arm 12 Since there is no relative rotation with 0, the second check force applying mechanism 170 does not function. Only Then, when the hinge arm 120 rotates about the first pivot 131 as described above, A third support press-fitted and supported in a hole formed in the third boss 126 of the hinge arm 120. The roller 163 supported by the holding shaft 164 is the first recess of the cam plate 161. The engagement with 161A is released and the cam plate 161 rolls on the arcuate cam surface. So Then, when the door reaches the 90-degree door opening position, the roller 163 engages with the second recess 161B. Therefore, the spring force of the spring 164 of the cam plate 161 is used to check the chain. Is applied.

[0040]   Next, the rear gate door 210 moves from the 90 degree open state to the 270 degree open state. Explain the work.

[0041]   From the 90 degree door open state shown in Fig. 9, the rear gate door 210 has a further door opening force. When applied, the second cam 142 fixed to the second hinge base 110 causes the second pivot 1 to move. The second lever which is trying to rotate around 32 and is in contact with the slope 142D thereof. Attempts to rotate 144 around the second support shaft 147. At this time, as described above, The cam follower portion 143A of the 1 lever 143 is released from contact with the arc portion 141A. The second lever 144 connected through the link member 145 is rotatable. Noh.

[0042]   Thus, the rear gate door 210 pivots about the second pivot 132 and is shown in FIG. The nearly 270 degree open door state shown is obtained. In addition, from 90 degrees to 270 degrees When rotating 180 degrees, the cam follower portion 144A of the second lever 144 moves to the second cam. It will slide on the arc portion 142C of 142.

[0043]   As is apparent from the above description, the arc portion 142C of the second cam 142 is substantially a semicircle. The circular arc portion 141C of the first cam 141 needs to have a circumference of about 1/4 of the circumference. Good. However, considering the cost reduction due to the shared use of parts, the first cam 141 The second cam 142 may be the same.

[0044]   Also, during the door opening operation from 90 degrees to 270 degrees, the second check force is applied. The applying mechanism 170 functions.

[0045]   That is, the rear gate door 5 is further rotated from the state shown by the phantom line in FIG. Then, the hinge arm 120 and, by extension, the fourth support shaft for supporting the L-shaped lever 171. A check cam 174 fixed to the second hinge base 110 is provided while 172 remains stationary. Rotates about the second pivot 132.

[0046]   Then, in the state shown in FIG. 5, the check cam 174 and the first flat portion 174B are connected to each other. The check force is applied by the contact of the spring 176 with the blade 173. The arc portion 174A of the check cam 174 and the roller 173 come into contact with each other from the opened position. The roller 173 will come into contact with the second flat portion 174C after the intermediate position is overcome. It In this state, the L-shaped lever 171 urged by the spring 176 causes The roller 173 is pressed by the flat portion 174C and a check force is applied.

[0047]   Next, a backlash removing operation in the hinge mechanism of this embodiment will be described.

[0048]   When the rear gate door 210 shown in FIG. 4 is fully closed, the second adjustment screw 183 When tightening and pressing the second side wall portion 124 of the hinge arm 120, the hinge arm 1 The second lever 144 supported by the second support shaft 147 is also pushed by The cam follower portion 144 </ b> A strongly contacts the slope portion 142 </ b> D of the second cam 142. Then, the second lever 144 rotates around the second support shaft 147 (clockwise in FIG. 4). ) Is applied to the first lever 143 via the link member 145. Reached and presses the cam follower portion 143A against the circular arc portion 141C of the first cam 141. Kick

[0049]   Thus, the hinge arm 120 and the first and second hinge bases 100 and 1 Backlash with the first and second pivots 131 and 132 respectively supported by At the same time, the first lever 143, the second lever 144, and the both are connected at the same time. The play between the link members 145 that are to be removed is removed.

[0050]   On the other hand, when the rear gate door 210 shown in FIG. The 1st adjustment screw 181 is tightened, and the tip end thereof comes into contact with the second side plate portion 104. Do And the first side wall portion 123 with which the first adjusting screw 181 is screwed, and by extension, the hinge. The arm 120 and the first lever supported by the first support shaft 146. 143 is pressed by its reaction force, and its cam follower portion 143A is moved to the first cam. It strongly abuts the slope portion 141D of 141. As a result, as in the case described above, the first A rotational force is applied to the lever 143, and the second lever 144 is attached via the link member 145. And the cam follower portion 144A is transmitted to the arc portion 142C of the second cam 142. It will be pressed and the backlash will be removed.

[0051]   The hinge mechanism according to the present invention is installed in the vehicle for the above-mentioned adjustment for removing backlash. It can be done before applying.

[0052]   In addition, the first and second adjustment screws 181 and 183 are set to the stoppers as described above. Since it also functions as, to reduce the hitting sound at the time of collision, its tip You may make it provide an elastic body.
