[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge mechanism for an opening / closing body such as a vehicle trunk lid.

[0002]

2. Description of the Related Art As a conventional hinge mechanism for a trunk lid, for example, those shown in FIGS. 6 and 7 are known (for a similar technique, see Japanese Utility Model Laid-Open No. 64-1066).

A trunk lid 1 covers a trunk room opening 2 provided at a rear portion of a vehicle body. A vertical surface portion 2a is formed on both left and right edges of the luggage compartment opening 2, and a horizontal shelf portion 2b is formed below the vertical surface portion 2a. A long plate-shaped lower bracket 3 is attached to the vertical surface portion 2a. That is, a horizontal adjustment hole 4 for adjusting the front-back position is formed at the front end of the lower bracket 3, a vertical adjustment hole 5 for adjusting the vertical position is formed at the rear end, and a circular adjustment hole is formed in the center. Adjusting holes 6 are formed, and the adjusting holes 4, 5 and 6 are attached to the vertical surface portion 2a by unillustrated bolts. Therefore, each adjustment hole 4,
The front-rear position and the inclination angle of the lower bracket 3 can be changed within the range of the dimensions 5 and 6. In addition, before and after the central hole 6 of the lower bracket 3, mounting points 3a, 3 for pivotally supporting lower ends of front and rear link members 7, 8 described later are provided.
b is also set.

On the other hand, an upper bracket 9 having an L-shaped cross section is fixed to the lower surface of the front end portion of the trunk lid 1, and mounting points 9a and 9b are also set at the front and rear of the upper bracket 9. The front mounting points 3a and 9a of the lower bracket 3 and the upper bracket 9 and the rear mounting points 3b and 9b of the upper bracket 9 are connected to each other by a pair of front and rear link members 7 and 8.
Are connected with.

As a result, the lower bracket 3 and the upper bracket 9 are rotatably connected by the front and rear link members 7 and 8, and the rear end side of the entire trunk lid 1 can be opened upward to enter the trunk room opening 2. You can load and unload luggage. A bumper bar 10 is set on the front side of the trunk room opening 2 and comes into contact with the front end portion of the trunk lid 1 when the trunk lid 1 is closed.

[0006]

In the prior art as described above, mainly with respect to the inclination angle of the trunk lid 1, a vertically elongated adjustment hole 5 formed at the rear end of the lower bracket 3 in the process of assembling the trunk lid 1. Is used to adjust the inclination angle of the trunk lid 1 to match the upper surface position of the trunk lid 1 with the vehicle body lines L on both sides of the trunk room opening 2. Even if accurate adjustment is performed, a gap d is generated between the upper surface of the trunk lid 1 and the vehicle body line L in the process of adding auxiliary components such as gas stays and weather strips performed after the building process. There is a risk. For this reason, conventionally, further readjustment is required after the step of adding the accessory parts, but the readjustment work inside the trunk room opening 2 after once attaching the trunk lid 1 is extremely difficult because the work space is limited. This is troublesome and causes the readjustment work to reduce the overall efficiency of the work of attaching the trunk lid 1.

The present invention has been made by paying attention to such a conventional technique, and provides a hinge mechanism for an opening / closing body which can easily adjust the installation of the opening / closing body such as a trunk lid. .

[0008]

In order to achieve the above-mentioned object, a hinge mechanism for an opening / closing body according to the present invention comprises an upper bracket, a fixing bracket attached to the opening / closing body, and
It is composed of a movable bracket to which the front and rear link members are connected, the movable bracket is rotatably attached to the fixed bracket, and the rotational position of the movable bracket with respect to the fixed bracket is made variable by an adjusting means. There is.

[0009]

According to the present invention, the adjustment means changes the rotational position of the movable bracket relative to the fixed bracket so that the lower bracket fixed to the vehicle body side and the fixed bracket fixed to the opening / closing body side can be moved relative to each other. Since the target inclination angle changes, the inclination angle of the opening / closing body can be easily adjusted, and the work efficiency can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted.

The opening / closing link mechanism of this embodiment is characterized by the structure of the upper bracket 11. That is, the upper bracket 11 according to this embodiment includes a fixed bracket 12 attached to the trunk lid 1 as an "opening / closing body",
It comprises a movable bracket 13 to which the upper ends of the front and rear link members 7, 8 are connected. The fixed bracket 12 has an L-shaped cross section formed of a horizontal portion 14 attached to the lower surface of the trunk lid 1 and a vertical portion 15 attached to the movable bracket 13. A curved notch 16 is also formed in the center of the vertical portion 15. Furthermore,
A vertical projection piece 17 is formed at the rearmost portion of the vertical portion 15, and a feed screw type pinion 18 is provided between the vertical projection pieces 17.
Is provided. Hexagonal head 18a of this pinion 18
Is located below the lower protruding piece 17, and the pinion 18 can be rotated in the forward and reverse directions by rotating the hexagonal head 18a with a tool.

On the other hand, the movable bracket 13 has a substantially long plate shape, and the front end portion of the movable bracket 13 and the upper end of the front link member 7 are pivoted to the front position of the vertical portion 15 of the fixed bracket 12 by the hinge pin 19. It is supported. Further, an upper end of the rear link member 8 is pivotally supported by a hinge pin 20 at an intermediate position of the movable bracket 13. Since the hinge pin 20 is located in the cutout portion 16, the hinge pin 20 does not interfere with the vertical portion 15. Further, a circular arc hole 21 is formed in the rear portion of the movable bracket 13, and a screw portion 22a of a welding bolt 22 fixed to the vertical portion 15 is movably engaged in the circular arc hole 21. A nut 23 is fastened to the threaded portion 22 a engaged with 21. A gear tooth-shaped rack 24 is formed on the end surface of the rearmost portion of the movable bracket 13. The rack 24 is engaged with the pinion 18 to form “adjusting means”, and by rotating the pinion 18, the portion of the rack 24 is moved up and down, and the movable bracket 13 is centered on the hinge pin 19. It turns up and down.

Next, a readjustment work procedure regarding the inclination angle of the trunk lid 1 will be described. After the trunk lid 1 is installed in the trunk room opening 2 and additional parts such as a gas stay and a weather strip are added, and if the upper surface position of the trunk lid 1 does not match the vehicle body line L, first, the trunk lid 1 Is opened, and then the nut 23 of the movable bracket 13 is loosened so that the movable member 13 can rotate about the hinge pin 19 on the front side. Then, the hexagonal head portion 18a of the pinion 18 is rotated by a tool to move the rack 24 engaged with the pinion 18 to the upper side or the lower side, whereby the movable bracket 13
Rotate. When the movable bracket 13 rotates, the relative position of the hinge pins 19 and 20, which are the upper mounting points of the front and rear link members 7 and 8 with respect to the fixed bracket 12, changes, so the inclination angle of the trunk lid 1 changes. Therefore, the operator may check the displacement direction of the inclination angle of the trunk lid 1 and rotate the movable bracket 13 in a direction to correct the displacement direction. Once the optimum rotation position of the movable bracket 13 with respect to the fixed bracket 12 is determined, the nut 23
Is fastened to fix its rotation position. This completes the readjustment work of the tilt angle of the trunk lid 1. In order to work with the trunk lid 1 open,
The rotation work of the hexagonal head portion 18a of the pinion 18 is performed in an open work space, and the workability is very good. Further, since the rotary position of the movable bracket 13 is adjusted using the rack 24 and the pinion 18, fine adjustment is possible, and the upper surface position of the trunk lid 1 can be perfectly matched with the vehicle body line L.

In the above description, the upper end of the front link member 7 is pivotally supported together with the movable bracket 13 on the fixed bracket 12, and the hinge pin 19 at the front end of the movable bracket 13 is used as the pivot point of the movable bracket 13. Alternatively, the hinge pin 20 may be used as a fulcrum and the hinge pin 19 on the front side of the movable bracket 13 may be in a free state.

[0015]

The hinge mechanism of the opening / closing body according to the present invention,
With the contents described above, the lower bracket fixed to the vehicle body side and the fixed bracket fixed to the opening / closing body side are simply changed by changing the rotational position of the movable bracket with respect to the fixed bracket by the adjusting means. Since the relative inclination angle with respect to changes, the inclination angle of the opening / closing body can be easily adjusted, and the working efficiency can be improved.
