〔Example〕

2 to 7 show a first embodiment of the present invention, and the same members as those in the above-mentioned conventional device are designated by the same reference numerals, and the explanation thereof will be omitted.

The trunk lid 11 includes an openable and closable upper lid 12 that covers the upper surface of the trunk compartment 10 in the vehicle body 21.
and a rear lid 13 for covering the rear surface of the trunk 10, and the front end of the upper lid 12 is hinged to the vehicle body 21 with a hinge 2 like a conventional trunk.

On the rear inner surface of the upper lid 12, parallel to it,
A storage frame 14 is fixed to the storage frame 14, which faces in the front-rear direction when the trunk lid 11 is closed and is large enough to insert and support the rear lid 13 from the rear end.

As shown in FIGS. 5 and 6, the left and right sides 14a of the storage frame 14 are provided with a first guide slot 15 and a second guide slot 16 in two stages, upper and lower, which are parallel to the top cover 12. , the relative positions of their rear ends are determined to be upper rear and lower front, and an arc-shaped widened portion 15a is provided at the upper rear end of the first guide elongated hole 15.

Further, at the rear end of the lower piece 14b of the storage frame 14, a stopper 17 that is curved downward and also serves as a guide is connected.

At the upper ends of both sides of the rear lid 13 when the trunk lid 11 is closed, there are guide rods 1 facing left and right.
8 is passed through the guide rod 18, and a guide pin 19 that is parallel to the guide rod 18 is protruded from the rear lid 13 at a slightly lower front side of the guide rod 18.

The guide rod 18 and the guide pin 19 are respectively
When the trunk lid 11 is closed by engaging with the second guide slots 15 and 16, the upper front surface of the rear lid 13 is in contact with the stopper 17 slightly below the guide pin 19.

At both ends of the guide rod 18, there are connecting rods 20 facing forward.
The rear ends of each connecting rod 20 are connected to each other, and the front end of each connecting rod 20 is connected to the pivot shaft 2a of the hinge 2 in the vehicle body 21.
It is pivotally mounted further rearward with a bearing fitting 22.

Thus, the storage frame 14, the guide rod 18, the guide pin 19, the link rod 20, etc. form a link device 23 between the top cover and the rear cover.

In the above-mentioned device, as shown by the solid line in FIG. 3, the upper lid 12 is substantially horizontal and covers the upper surface of the trunk compartment 10, and the rear lid 13 hangs down from the upper lid 12 to cover the rear surface of the trunk compartment 10 in the closed position. When the trunk lid 11 is opened upward by unlocking the locking device 7 using a key or an opener (not shown), the front end position of the linking rod 20, which is pivotally connected by a bearing fitting 22, is located at the upper lid. 1
Since the rear cover 13 is located rearward of the pivot shaft 2a of the hinge 2 to which the hinge 2 is pivotally attached, the rear lid 13 is pulled forward together with the guide rod 18 via the linking rod 20.

Then, the rear cover 13 tries to move forward, but the stopper 17 located below the guide rod 18 prevents it from moving forward, and it moves in the direction of the arrow in FIG.
The guide rod 18 and the guide pin 19 move to the first and second guide lengths as the top cover 12 opens upward as shown by the imaginary line A in FIG. By sliding forward in the holes 15 and 16, the rear cover 13 is drawn into the storage frame 14,
When the top lid 12 is fully opened as shown by the imaginary line B in FIG. 3, the rear lid 13 reaches the storage position where it is folded substantially parallel to the top lid 12, as shown in FIG.

When the trunk lid 11 is lowered, each member operates in the opposite manner to that described above, and as the top lid 12 swings downward, the rear lid 13 is pushed by the linking rod 20 and moves inside the storage frame 14 with the top lid 12. Stay parallel and move back.

When the guide pin 19 reaches the rear end of the second guide slot 16, the rear cover 13 is further pushed by the linking rod 20.
The guide rod 18 rotates the arc-shaped widened portion 15a at the rear end of the first guide elongated hole 15 around the guide pin 19, thereby moving downward until the upper inner surface of the rear cover 13 comes into contact with the stopper 17. Then, the locking device 7 returns to the closed position shown in FIG. 5, and the locking device 7 engages with the striker 8 to be locked.

In addition, in the above, instead of the arc-shaped widened portion 15a of the first guide slot 15, the rear end of the second guide slot 16 may be shaped like a downward hook, or the guide rod 18
By providing some play between the guide pin 19 and the first guide slot 15 and between the guide pin 19 and the second guide slot 16, the arc-shaped widened portion 15a may be omitted.

Also, when the trunk lid 11 is closed,
In the case of a car in which the rear lid 13 is oriented vertically, when the trunk lid 11 is closed, the rear lid 13 becomes almost vertical due to its own weight. In addition, by providing an appropriate guide device, the second guide slot 16, guide pin 19, and stopper 17 can be omitted.

In this first embodiment, in addition to being able to achieve the same effects as described above as the effects of the present invention, when the top cover 12 is opened, the rear cover 13 once rotates outward, and then the top cover 12 Since the rear cover 13 is pulled in parallel, it does not come into contact with luggage in the trunk 10 or obstruct the space in the trunk 10, which is advantageous in that it is convenient.

FIG. 8 shows a second embodiment of the invention.

In this example, the rear lid 24 is rotatable between a closed position shown by a solid line and a storage position shown by an imaginary line.
A coil spring 2 is pivotally attached to the rear lower surface of the top cover 26 with a shaft 25 and is wound around the shaft 25.
One end of 7 is attached to the rear lid 24, and the other end is attached to the upper lid 2.
6, the rear cover 24 is locked.
is constantly biased toward the closed position.

Further, a first gear 29 that rotates integrally with the hinge 28 is pivotally supported on the hinge shaft 28a of the hinge 28, which is the center of rotation of the upper lid 26, and a second gear 30 that meshes with the first gear 29. By pivoting the winding drum 31, which is integrated with the second gear 30, to the vehicle body with a bracket 32, the winding drum 31 is linked to the opening/closing operation of the top cover 26, and the winding drum 31 is integrated with the second gear 30. It is designed to rotate in a clockwise winding direction in FIG. 8 and in an opposite unraveling direction.

Furthermore, a cable 33 such as a wire with one end fixed to the middle part of the rear cover 24 is guided along the upper cover 26 with an appropriate guide piece 34, and the other end of the cable 33 is wound up. By winding it up on the drum 31, the winding drum 31 winds up and unwinds the cable 33 in conjunction with the opening/closing operation of the top lid 26, and the rear lid 24 resists the biasing force of the winding spring 27. It is designed so that it can be pulled to the storage position or returned to the closed position by the biasing force of the coil spring 27.

In this way, the linking device 35 between the top lid and the rear lid,
By configuring the shaft 25, the coiled spring 27, the winding drum 31, the cable 33, etc.,
As described above as the effects of the present invention, similar effects can be achieved.

In the second embodiment, when the trunk lid is completely closed, the cables 33 are slightly loosened, so that the rotation of the rear lid 24 can be started after the upper lid 26 has been lifted above the trunk. If the rear lid 24 is folded, it is possible to prevent the rear lid 24 from rotating inside the trunk room and coming into contact with luggage.

Further, as shown in FIG. 9, the first gear 29' is fixed to the vehicle body, and the winding drum 31', which is integrated with the second gear 30' that meshes with the first gear 29', is attached with a bracket 32'. , it may be implemented by being pivotally supported on the upper lid 26 side.

In this case, the winding direction of the winding drum 31' is simply reversed from that of the second embodiment;
It operates almost the same as the embodiment.

As described above, in the present invention, the linking device between the top lid and the rear lid can be formed using any device as long as it can move the rear lid between the storage position and the closed position in conjunction with the opening/closing operation of the top lid. For example, in addition to the above-mentioned mechanism, a gear linkage mechanism, a winding linkage mechanism, etc. may be used.
