DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a roof hinge structure for a wing type rear body.

[0002]

2. Description of the Related Art A wing-type rear body as shown in FIG. 6 is known as a truck bed. In this case, the wing grooves 2a, 2b (forming a half of the roof from one side of the side) are attached at the center of the roof of the rear body 1 via hinges (not shown) so as to be openable and closable in the vertical direction.

As such a roof hinge structure of a wing-type rear body, one provided with a strength member called a center beam extending in the front-rear direction at the center of the roof of the rear body is often adopted (Japanese Utility Model Laid-Open No. 2-38320).
FIG. 7 shows an example of such a center beam. Reference numeral 3 denotes a center beam at the center of the roof, and hinges 4a and 4b are provided on both sides thereof.
The left and right wing grooves 2a, 2b are supported so as to be openable and closable in the vertical direction.

The hinges 4a and 4b include a male hinge 5 connected to the center beam 3, a female hinge 6 connected to the roof center rails 8a and 8b, respectively, and a hinge pin 7 for rotatably connecting the female hinge 6 to the male hinge 5. The winggrooves 2a and 2b are formed with the roof center rails 8a and 8b as a part of the skeleton. Reference numeral 9 denotes a center sheet that covers a gap between the wing grooves 2a and 2b on both sides.

In this type, since the two rotation centers (hinge pins) are fixed due to the rigidity of the center beam 3, the roofs on both sides are fluttered arbitrarily by the running vibration of the vehicle when the wing grooves 2a and 2b are closed. In addition to being able to support the load applied to the roof from the outside, the center beam 3 is of course heavy. Can be

Therefore, a roof hinge structure without a center beam as shown in FIG.
No. 2). One hinge pin 7 is arranged at the center of the roof, and a rotatable female hinge 6 is provided around the pin 7 as a fulcrum. The wing roofs 2a, 2b are connected to the female hinges 6 via roof center rails 8a, 8b, and can be opened and closed in the vertical direction about the hinge pins 7 as a center of rotation.

In this type, the center of rotation is one, and the wing grooves 2a and 2b are directly connected to each other by the hinge pin 7, so that the roof on both sides can be prevented from fluttering.
An external force applied to one wing groove 2a or 2b is transmitted to the other wing groove 2b or 2a via the hinge pin 7 (that is, each wing groove 2a, 2a, 2b).
The external force is supported by the roof as a whole with the support force for restricting the 2b in the closed state), but when the wing grooves 2a and 2b are opened upward (both sides of the body are fully opened), the center sheet 9 is sandwiched between the gaps. Easy to fit. In addition, since the winggrooves 2a and 2b have the same rotation center, the winggrooves 2a and 2b on both sides must be assembled together on the gate of the body. Was.

Therefore, as a roof hinge structure having no center beam at the center of the roof, a structure as shown in FIG. 9 can be considered. A male hinge 5 is arranged at the center of the roof, and a female hinge 6 which is rotatable on both sides thereof via hinge pins 7 respectively.
Is provided. The wing roofs 2a, 2b are connected to the female hinge 6 via roof center rails 8a, 8b,
The hinge pins 7 are supported so as to be openable and closable in the vertical direction around the hinge pins 7.

[0009]

However, in this case, contrary to the type shown in FIG. 8, the center sheet 9 is not sandwiched and the assembling of the wing grooves 2a and 2b is facilitated. 5 swings, the roofs on both sides move up and down without permission (that is,
In addition, when an external force acts on one wing groove 2a or 2b as shown in FIG. 10, the male hinge 5 applies the load to the other wing groove 2b or 2b.
Since the information is not transmitted to a, there is a drawback that a load is applied only to one of the wing grooves 2a or 2b.

An object of the present invention is to provide an effective countermeasure for solving such a problem.

[0011]

According to a first aspect of the present invention, in a wing-type rear body of a vehicle, a male hinge is provided at a roof center of the rear body, and left and right wing grooves are vertically moved via female hinges on both sides thereof with hinge pins as fulcrums. A hinge stopper is provided on at least one of the female hinges, which supports the female hinge so as to be openable and closable, and locks the movement toward the closed side between the female hinges when both wing grooves are in the closed state.

According to a second aspect of the present invention, in a wing type rear body of a vehicle, a male hinge is provided at a roof center of the rear body, and left and right wing grooves are supported on both sides thereof via female hinges with hinge pins as fulcrums so as to be openable and closable in a vertical direction. On the other hand, a hinge stopper is provided for locking the movement of each female hinge toward the closed side between the female hinge and the male hinge when both wing grooves are in the closed state.

According to a third aspect, in the first or second aspect, at least a locking surface of the hinge stopper is formed of a resin having a small friction coefficient.

[0014]

According to the first aspect of the present invention, when the wing grooves on both sides are in the closed state, the hinge stopper locks the movement on the closed side between the female hinges, so that the male hinge is also held in a fixed state. Therefore, the upward and downward movement (fluttering) of each roof while swinging the male hinge due to the running vibration of the vehicle and the like can be properly restricted by the hinge stopper between the female hinges. In this closed state, if an external force is applied to one roof, this load is transmitted to the other roof via the hinge stopper, so that the external force is supported as a whole roof by the support force that restrains each wing groove in the closed state. Can be That is, it is possible to prevent the load from being concentrated only on one of the wing grooves due to the load on the roof.

According to the second aspect of the present invention, when the wing grooves on both sides are closed, the movement of each female hinge toward the closed side is locked between the hinge stopper and the male hinge, so that the male hinge is also held in a fixed state. Is done. for that reason,
Each roof can be prevented from moving up and down (with flutter) while swinging the male hinge due to the vibration of the vehicle.
In this closed state, when an external force is applied to one roof, this load is transmitted to the other roof through hinge stoppers that lock each female hinge between the female hinge and the male hinge. The external force can be supported by the roof as a whole with the support force restricted to the roof. That is, it is possible to prevent the load from being concentrated only on one of the wing grooves due to the load on the roof.

According to the third aspect of the present invention, since the locking surface of the hinge stopper is made of a resin having a small friction coefficient, it is possible to alleviate the impact at the time of locking by the hinge stopper and prevent the metal from rubbing.
