Description

[Detailed description of the invention] This invention involves attaching a movable lid to the vehicle roof in order to ventilate the interior of the vehicle.The movable lid is brought into contact with and separated from the vehicle roof to open and close an opening provided in the vehicle roof. Regarding roof ventilators.

In this type of roof ventilator, it is desirable that the lid body be movable at angles in various directions relative to the vehicle body, taking into consideration weather conditions such as the moon, rain, temperature, and solar radiation.

Therefore, conventionally, the West German Published Patent Publication
In addition to raising the entire lid as disclosed in AUSLEGE-SCHRIFT1240424,
There are roof ventilators that allow only the front end, rear end, left end, and right end of the lid to be moved upward.

As shown in FIG. 1, the structure of the roof opening 12a is a cover 10a, which is provided with first and second cylindrical guide members 15 (one of the guide members is shown in FIG. 1).
Further, a partition means 17 is fixedly disposed in the center of each guide member 15.
Pistons 13 are inserted into both ends of the guide member 15 via coil springs 16 arranged on both sides of the partition means 17. Links 14 are pivotally attached to both pistons 13 and pivotally supported on the vehicle roof 11a.
The vehicle roof 11a is restricted from turning about the pivot axis B to hold the cover 10a in the upper position around the pivot axis A of the link 14 to the piston 13.
An engagement surface 14a is formed on the link 14 side, and an engagement pin 13a is formed on the piston 13 side.

Therefore, when the piston 13 is inserted into the guide member 15, the piston 13 is urged toward the outside of the guide member 15 by the coil spring 16. Therefore, there was a drawback that the piston 13 could not be held within the guide member 15 and assembly was difficult.

Therefore, an object of the present invention is to guide and hold the link on the guide member through a guide groove formed in the guide member, thereby improving assemblability.

The technical means is to attach the first and second guide rails to the lid body, to arrange the shoes at each end of these guide rails so as to be able to slide freely via springs, and to connect these shoes to both guide rails. One end of each link is connected to one end of the rail by a ball joint through a guide groove formed on the side surface of each end of the rail.

Therefore, in the roof ventilator of the present invention, since the link is connected to the shoe disposed in the guide rail through the guide groove formed on the side surface of the guide rail, even if the link is biased by the spring, The link will not fall off the guide rail. Therefore, assembly becomes easy and the object of the present invention is achieved.

Furthermore, since the shoe disposed within the guide rail and one end of the link are connected by a ball joint, the shoe can rotate together with the guide rail around one end of the link. Therefore, the shoe does not receive any torsional force from the spring biasing the shoe.
Therefore, the shoe slides smoothly within the guide rail, and the roof ventilator operates smoothly.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

It is press-fitted into the assembly. At this time, the shoe 5 is
Since it is arranged with a clarity on h,
There is no problem with press-fitting. Moreover, once press-fitted, the link 7, shoe 5, and spring 3 will not fall out of the guide rail 23.

Next, the operation of this embodiment will be explained. First, the operation of the lift means 20 will be explained. As shown in FIG. 6, the links 7, 7 are urged to rotate clockwise around the pins 8, 8 via the shoes 5, 5 by the springs 3, 3. Therefore, the side surfaces 7d, 7d of the links 7, 7 are brought into contact with the contact surfaces 9f, 9f of the plate 9, and the links 7, 7 are held in this position.

One of the links 7, 7 is rotated counterclockwise in the drawing around the pin 8 against the biasing force of the spring 5. The rotation of this link 7 causes the guide rail 2 to
One side of 3 is raised. Accordingly, when the biasing force of the spring 3 exceeds the position toward the pin 8, the link 7 is biased clockwise in the figure by the spring 3. Therefore, the link 7 is rotated by the biasing force of the spring 3, and its side surface 7c comes into contact with the contact surface 9e of the plate 9, and the link 7 is held in this position. Therefore, one end of the guide rail 23 is raised and inclined (FIG. 7).

Note that the guide groove 2b becomes narrower toward the center of the guide rail 23. Anyway, link 7
Although the spring 3 is compressed and deformed in accordance with the rotation of the guide groove 2b, it does not protrude from the guide groove 2b. Therefore, the link 7 rotates smoothly.

If the other link 7 is also raised, it will be held in the raised position in the same way, and the guide rail 23 will rise in parallel as shown in FIG.

Since the two lift means 20 that operate in this manner are installed in parallel in the longitudinal direction of the vehicle, the lid body 10
works as follows. That is, when each link 7 is lowered, the lid body 10
Close. Next, when both links 7, 7 of one of the lift means 20 are raised, the lid body 10 opens at the right end or opens at the right end as shown by the solid line in FIG.
The left end is in an open state as shown by the dotted chain line.

At this time, each guide rail 23, 23 is connected to each shoe 5 disposed within the guide rail 23, 23.
When the pin 6 rotates around the head 6a of the pin 6, it becomes inclined with respect to the link 7.

Further, when the links 7 of each link means 20 located on the front side of the vehicle are raised together, the front end of the lid 10 is opened as shown by the solid line in FIG. 10. On the other hand, when the links 7 located on the rear side of the vehicle are both raised, the rear end opens as shown by the two-dot chain line in FIG.

When all the links 7 are further raised, the lid 10 becomes horizontal as shown in FIG. 8, and the opening 12 of the roof 11 is fully opened.
