Abstract

PROBLEM TO BE SOLVED: To automatically form a ventilation gap on a shade for ventilation when a lid is tilted up in the closed state of the shade and allow the shade to fully exert the shielding function during ventilation in a tilt-up type lid device for a vehicle tiltably fitted with the lid at an opening section provided on the roof of the vehicle and fitted with the longitudinally halved shade longitudinally slidably to the lower section of the lid. SOLUTION: When a lid 2 is tilted up in the fully closed state of the lid 2 and a shade 3, the rear section of a front shade 31 is lifted interlockingly with the tilt-up action, and a ventilating gap H is formed in the vertical direction between the rear section of the front shade 31 and the front section of a rear shade 32 for ventilation. Since the ventilating gap H is formed above the front section of the rear shade 32 in this ventilation state, the shade 3 can fully exert the shielding function.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shade opening / closing mechanism of a tilt-up type lid device mounted on a vehicle roof.

[0002]

2. Description of the Related Art An opening is provided in a part of a roof of a vehicle, and a lid (for example, a glass lid) is mounted on the opening so as to be rotatable up and down around a front side thereof as a hinge, and an operation of a tilt-up unit is performed. Thereby, the lid is opened and closed between a fully closed state in which the lid is flush with the roof and the opening is closed, and a tilt-up state in which the rear part of the lid is lifted upward. Lid devices have been widely used conventionally.

[0003] A shade for the purpose of blocking light is attached to the interior side of the tilt-up type lid so as to be slidable in the front-rear direction. The shade is slid rearward to open and slid forward to close. However, since it is very difficult to secure the storage space for the shade when it is slid backward and opened, the shade is divided into many parts back and forth, and the other divided shades are folded and stored in the storage part behind the opening. In many cases, it will be done.

However, in the case where the lid tilt-up operation and the shade opening / closing operation are performed independently of each other, if the lid is to be tilted up to perform ventilation, ventilation cannot be performed with the shade closed. Since the shade is not provided, the shade must be manually moved backward, which is troublesome. In addition, in order to allow ventilation without moving the shade rearward when the lid is tilted up, there is conventionally provided a part of the shade with a ventilation louver. Even when the vehicle is fully closed, light may enter the interior of the vehicle from the shade louvers of the shade, and the original purpose of shading the shade may not be achieved.

Therefore, in a tilt-up type lid device for a vehicle, the shade slides backward and opens in conjunction with the tilt-up operation of the lid, and slides forward and closes in conjunction with the tilt-down operation of the lid. Was developed, and Japanese Utility Model Publication No. 3-26007,
It is disclosed in Japanese Utility Model Laid-Open No. 6-22034.

[0006]

As described above, in the conventional apparatus in which the shade slides backward (opening operation) and forwardly slides (close operation) in conjunction with the tilt-up and tilt-down operations of the lid. When the lid is tilted up and ventilated, the shade is in an open state, so that sunlight enters the room, and if the shade is closed to block light, ventilation cannot be performed.
That is, there is a problem that ventilation cannot be performed in a state where light is blocked by the shade.

An object of the present invention is to solve the above-mentioned conventional problems.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a tilt-up type lid device in which a roof is tiltably mounted to an opening formed in a roof of a vehicle, and is divided into a plurality of parts at a lower portion of the lid.

In addition to giving a sense of moderation to the operation at the beginning of the opening operation and the end of the closing operation, the shade 3 is prevented from moving backward due to vibration of the vehicle body in the fully closed state of the shade 3 and the ventilation state shown in FIG. ing. In FIG. 3A, an upward projection 42a is formed on the lower surface of the upper shade guide groove 42, and the fully closed state of the shade 3 is held by the upper edge of the opening of the engaging portion 9a and the projection 42a. An example is shown, so that the shade 3 can be maintained in the fully closed state even more reliably.

In the above description, the so-called glass lid in which the lid is made of glass has been described. However, the present invention is not limited to the glass lid, and is applicable to a tilt-up type lid device using a transparent or translucent synthetic resin lid. It goes without saying that it is possible.

In the illustrated example, the shade 3 is divided into two parts, the front shade 31 and the rear shade 32. The shade 3 is divided into three or more parts before and after. The present invention is also applicable.

[0029]

As described above, according to the present invention, there is provided a tilt-up type lid device for a vehicle, wherein a plurality of shades which are mounted on a lower portion of the lid so as to be slidable backward and open are provided. When the shade is closed, the rear part of the front shade is lifted in conjunction with the tilt-up operation of the lid, and a vertical ventilation gap is formed between the front shade and the rear part of the rear shade. By providing an interlocking mechanism that lowers the rear part of the front shade and returns it to the closed state in conjunction with the tilt down of the lid, if the lid is tilted up, a ventilation gap is automatically formed in the shade. When the lid is tilted down, the shade automatically returns to the closed state when the lid is tilted down, which is very convenient and the ventilation gap is located at the rear of the front shade. Since the gap is formed above the front part of the shade on the rear side by shaking, the shade can sufficiently fulfill the light shielding function even during the ventilation of the vehicle interior, and it is possible to achieve both the ventilation and the light shielding. The mechanism for interlocking the shade up / down operation and the shade with the lid is extremely simple in construction, minimizing the addition of new parts, and is extremely inexpensive. Thus, a great effect can be brought about practically. .
