Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to FIG. 1, a flip-up hatch (window) 10 of a vehicle 1 to which a flip-up window structure according to the present invention is applied is shown in a perspective view.
As shown in the figure, the hatch 10 functions as a window of a tailgate (vehicle body member) 2 of the vehicle 1 and is configured to be able to open and close the opening 4 of the tailgate 2 by a jumping operation.

  The hatch 10 is pivotally connected to the tailgate 2 via a pair of hinges (connecting members) 20, 20 at the upper end and is tailed via a pair of gas springs (connecting members) 22, 22 on both sides. A striker (connecting member) 32 that cooperates with a lock unit 30 provided in the tailgate 2 when closed is connected to the gate 2.

As a result, the vehicle 1 can generally open and close the tailgate 2, and opens and closes by opening only the hatch 10 around the hinges 20 and 20 without opening and closing the tailgate 2 by unlocking the lock unit 30. Is possible.
Referring to FIG. 2, the rear surface of the hatch 10 as viewed from the direction of arrow A in FIG. 1 is shown. Referring to FIG. 3, a cross-sectional view taken along line BB in FIG. Details of the structure of the hatch 10 will be described with reference to FIGS.

  The hatch 10 is composed of a hatch main body (window main body) 12 made of transparent resin glass (for example, polycarbonate) and a reinforcing resin material 14 provided integrally on the periphery of the hatch main body 12. The reinforcing resin material 14 may be composed of a resin member (for example, polycarbonate) similar to the hatch main body 12, or other resin member (for example, a polymer of polypropylene and glass fiber) as long as it has sufficient strength. Etc.). Further, the reinforcing resin material 14 does not need to be transparent and may be colored.

  Since the hatch main body 12 and the reinforcing resin material 14 are both made of a resin material, the hatch 10 is temporarily attached so that the hatch main body 12 and the reinforcing resin material 14 are completely brought into close contact by multilayer molding or multicolor molding. It is possible to mold it. In other words, the hatch main body 12 and the reinforcing resin material 14 can be integrally formed, whereby the hatch 10 can be easily formed. Multi-layer molding and multi-color molding are known molding methods and will not be described here.

  As described above, when the hatch body 12 and the reinforcing resin material 14 are integrally formed of a resin material, the resin material is lighter than inorganic glass (quartz glass or the like), and thus the hatch 10 can be easily reduced in weight. Since the resin material is richer in moldability than inorganic glass, the hatch 10 can be formed into a free shape (such as local irregularities). )can do. Further, the hatch 10 can be freely decorated or partially colored.

Furthermore, since the hatch main body 12 and the reinforcing resin material 14 are in close contact with each other and are integrally formed, sufficient strength and rigidity can be secured in the hatch 10.
In addition, the reinforcing resin material 14 is formed with a pair of reinforcing ribs 15 and 15 along the entire circumference along the outer peripheral edge and the inner peripheral edge. Thereby, the hatch main body 12 can be easily reinforced and effectively reinforced with the reinforcing resin material 14 while reducing the overall weight. Although the pair of reinforcing ribs 15 are provided here, sufficient effects can be obtained with only one of the reinforcing ribs 15, and the reinforcing rib 15 does not extend over the entire circumference. You may concentrate in the vicinity of the place which should reinforce intensively.

  Further, the reinforcing resin material 14 has other widths at the hinge 20, 20, the gas springs 22, 22 and the striker 32 attachment portion (connection portion), that is, the hinge attachment portion 16, the gas spring attachment portion 17, and the striker attachment portion 18. Compared with the part of FIG. That is, the reinforcement degree is set to be particularly high for the attachment portions of the hinges 20 and 20, the gas springs 22 and 22, and the striker 32. Thereby, it is possible to easily reinforce and effectively reinforce the portion to which the external force is applied in the reinforcing resin material 14 while reducing the overall weight.

By the way, as described above, if the hatch 10 is made of a resin material, it is rich in moldability and easy to perform multi-layer molding and multi-color molding. Therefore, a resin functional member (spoiler, lamp lens, weather, etc.) having an independent function together with the hatch 10. Strips and the like) can be integrally formed at the same time.
Referring to FIG. 4, as another embodiment, a case where a high-mount stop lamp spoiler 40 made of a resin material (for example, polycarbonate) is integrally formed on the hatch body 12 by multilayer molding is illustrated.

As described above, if the spoiler 40 can be integrally formed with the hatch 10 at the same time, it is not necessary to separately attach the spoiler, the cost can be reduced, and the vehicle 1 can be improved while improving the formability of the hatch 10. The appearance design performance can be easily improved.
In addition, although the high-mount stop lamp combined spoiler 40 was illustrated here, if it is a resin material, even if it is a spoiler alone, a high-mount stop lamp alone or another lamp alone, the same effect can be obtained. Can do.

Referring to FIG. 5, as another embodiment, a weather strip 50 made of a resin material (for example, thermal plastic olefin) is formed on the reinforcing rib 15 on the outer peripheral edge of the reinforcing resin material 14 by multilayer molding. The case of integral molding is illustrated.
As described above, if the weather strip 50 can be integrally formed with the hatch 10 at the same time, it is not necessary to separately attach the weather strip, so that the cost can be reduced and the moldability of the hatch 10 can be improved. The appearance design performance of the vehicle 1 can also be improved easily. In this case, there is also an advantage that the watertight performance can be improved.

Although the description of the embodiment of the flip-up window structure for a vehicle according to the present invention is finished above, the embodiment is not limited to the above.
For example, in the above-described embodiment, the hatch body 12 and the reinforcing resin material 14 are integrally formed by multilayer molding or multicolor molding. In this way, the same effect as described above can be obtained.

In the above embodiment, the hatch 10 of the tailgate 2 has been described as an example. However, the present invention is not limited to the hatch 10 of the tailgate 2 and opens and closes openings of other vehicle body members of the vehicle 1. If there are hatches to be applied, the same applies to them.
Moreover, in the said embodiment, although the reinforcement resin material 14 was provided continuously over the perimeter periphery of the hatch main body 12, you may make it provide intermittently in the periphery of the hatch main body 12 about a reinforcement resin material. Even in this way, the same effect as described above can be obtained to some extent.
