Description

[Detailed description of the invention] The present invention relates to a roof window of a vehicle, and has a structure in which a cover member that allows the window opening to be freely opened and closed is given a sufficient upward rotational posture to fully open the rear part of the window opening. The present invention also relates to the provision of a device aimed at preventing the interior of a vehicle from becoming narrower due to the compactness of the roof window.

2. Description of the Related Art A configuration in which a window opening is formed in the roof of a vehicle and a cover member is provided to open and close the window opening is well known. Conventionally, in this structure, the rear part of the cover member is rotated sufficiently upward, so that the rear part of the window opening is opened, and the interior of a vehicle such as a vehicle is sufficiently ventilated. However, in order to sufficiently rotate the cover member upward, the structure of the roof window becomes complicated and large, which causes the problem that the roof window protrudes into the vehicle compartment, making the interior of the vehicle compartment narrower.

The present invention has been devised in view of such conventional problems, and its features are that a window opening 2 is formed in the roof 1 of a vehicle;
Guide rails 6 are provided on both sides, and a drive body 7 and front and rear movable bodies 8 and 9, which are movable back and forth along the guide rails 6, are provided, and a cover member 13 is supported on the front movable body 8. The front end of the cover frame 14 is pivotally supported, the front part of the lifter 15 is pivotally supported by the rear movable body 9, and the rear end is pivotally supported by the front and rear middle part of the cover member 13, and the drive body 7 and the lifter 15 have a cam shaft 16 on one side. However, a cam groove 17 that engages with the camshaft 16 is provided on the other side, and when the driver 7 moves backward in the position facing the window opening 2 of the cover member 13, the camshaft 16
Through the relative movement of the cam groove 17 and the upward rotation of the rear end of the lifter 15 around the rear moving body 9,
The rear portion of the cover member 13 is able to rotate upwardly around the front movable body 8, and the rear portion of the window opening 2 is opened with the cover member 13 in this upwardly rotating position, and the cover member 13 is rotated upwardly. As the driver 7 moves backward from the position, the cover member 13 moves backward while maintaining the upward rotational position until the rear end of the lifter 15 reaches above the roof 1 behind the window opening 2. The point is that it is structured so that it is open to the public.

Hereinafter, embodiments of the present invention will be explained according to the drawings.
1 and 2, a roof 1 of a vehicle A as an example has a window opening 2 formed in its front part, and the window opening 2 has a sealing member 3 having an L-shaped cross section.
It is bordered with. A ceiling plate 4 forming the upper surface of the vehicle interior is fixed to the lower surface of the roof 1, and a window opening 2 is fixed to the lower surface of the roof 1.
The roof 1 and the ceiling plate 4 are spaced apart from each other, and a ceiling opening 5 corresponding to the window opening 2 is formed in the ceiling plate 4.

Guide rails 6 are provided on the upper surface of the ceiling plate 4 on both sides of the window opening 2, and a driving body 7 and a front/rear moving body 8, which are movable back and forth along the guide rails 6,
9 is provided. The driving body 7 includes a driving body main body 11 connected to a driving source such as an electric motor or a manual handle via an interlocking body 10 such as a wire that can be pushed and pulled.
and a pair of front and rear sliders 12, 12 protruding from the main body 11.
2 and the front/rear movable bodies 8, 9 are formed of a resin material or the like and have an elliptical shape when viewed from the side, and are fitted inside the guide rail 6 having a U-shaped cross section so as to be slidable back and forth.

The cover member 13 is removably fitted into the window opening 2 to open and close the window opening 2, and is made of transparent glass, a metal plate, a resin plate, etc. 2, the periphery of the cover member 13, especially the lower surface of the periphery, is fitted into the seal member 3.
A sealing function is achieved by pressing against the upper surface of the lower piece 3a, and the window opening 2 is closed.

The cover member 13 is supported by a pair of left and right cover frames 14 via brackets (not shown), and the front end of the cover frame 14 is pivotally supported by the front movable body 8 so as to be rotatable about a horizontal axis.

A pair of left and right lifters 15 are provided, and each lifter 15 has its front part pivoted to the rear movable body 9 and its rear end pivoted to the middle part of the cover member 13 in the front-rear direction via the cover frame 14. A camshaft 16 is provided on one side of the midway portion, and a cam groove 17 that engages with the camshaft 16 is provided on the other side, and these camshaft 16 and cam groove 17 constitute a cam device. In the illustrated example, front and rear cam shafts 16a and 16b are provided on the drive body 7 so as to protrude laterally from the axis, and a straight front cam groove 17a and a dogleg-shaped rear cam groove 1 are provided in the middle of the lifter 15.
7b is formed.

At the position facing the window opening 2 of the cover member 13, the camshaft 16 slides forward along the cam groove 17 due to the forward movement of the driving body 7 due to the operation of the driving source, and the lifter 15 moves to the rear moving body. 9, and the cover member 13 is rotated downward through the downward rotation of the cover frame 14, which rotates downward about the front moving body 8, and the cover member 13 is rotated downward. The window opening 2 is brought into a closed state (FIG. 2a). In the above case, the front camshaft 16a presses the upper surface of the front cam groove 17a, and the rear camshaft 16b presses the lower surface of the rear cam groove 17b. Also, camshaft 1
6 moves forward along the cam groove 17, the front end of the cover member 13 comes into contact with the vertical piece 3b of the seal member 3, or the forward movement of the cover member 13 is prevented by another stopper member.

On the other hand, at the position facing the window opening 2 of the cover member 13, the camshaft 16 slides rearward along the cam groove 17 due to the backward movement of the driver 7 due to the operation of the drive source, and the lifter 15 moves the rear moving body 9. The cover member 13 is rotated upward through the upward rotation of the cover frame 14, which rotates upward about the front moving body 8. Mainly the rear part of the opening 2 is left open (FIG. 2b). In this case, if the distance from the cam device to the cover frame 14 and the pivot portion 18 of the lifter 15 is larger than the distance from the rear movable body 9 to the cam device, the upper and lower positions of the cam shaft 16 and the cam groove 17 can be Even if the engagement distance in the direction is small, the pivot point 1
8 is rotated further upward, and thus the cover member 1
3 can be given a sufficient upward rotational attitude, and since the engagement distance between the cam shaft 16 and the cam groove 17 in the vertical direction is small, the roof window can be made particularly compact in the vertical direction.

The front end of the lifter 15 extends further forward, and an auxiliary moving body 19 is provided to protrude from the extended end. The auxiliary moving body 19 moves toward the guide rail 6 with the lifter 15 rotating upward and the cover member 13 in an upward rotating position.
The auxiliary movable body 19 is slidably fitted into the guide rail 6 at a position facing the window opening 2 of the cover member 13, while the cover member 13 rotates downward from the upward rotational position. After passing through the fitting notch 20, the fitting to the guide rail 6 is released. As described above, when the camshaft 16 moves backward along the cam groove 17, the auxiliary moving body 19 comes into contact with the front surface 20a of the engagement notch 20, thereby preventing the cover member 13 from moving backward.

As described above, when the cover member 13 and the window opening 2 face each other, the pivot point 21 of the front moving body 8 and the cover frame 14 is located forward of the front edge of the window opening 2, and the cover member 13 is moved upward. When rotating, the front edge of the cover member 13 gradually rotates upward without descending, thereby avoiding unnecessary pressure contact between the front edge of the cover member 13 and the seal member 3 when the cover member 13 rotates upward. be done.

The driver 7 from the upward rotational position of the cover member 13
By rearward driving, the rear moving body 9 sliding on the guide rail 6 and the auxiliary moving body 19 cooperate to hold the lifter 15 in an upward rotational posture, thereby causing the upward rotation of the cover member 13. The posture is maintained and the window opening 2 is opened (FIG. 2c).

Therefore, when the window opening 2 is fully opened due to the rearward movement of the cover member 13, the cover frame 14 and the pivot portion 18 of the lifter portion 15 are configured to be positioned rearward from the rear edge of the window opening 2.

FIG. 3 shows another embodiment of the present invention, in which the front movable body 8
and the pivot point 21 of the cover frame 14 is the window opening 2
It is located near the lower part of the front edge, and therefore, when the cover member 13 moves up and down, the contact distance between the front edge of the cover member 13 and the inner surface of the vertical piece 3b of the seal member 3 is made as small as possible. has been done.

Further, the cam shaft 16 and the cam groove 17 are connected to the window opening 2.
is single on each side. In addition, the auxiliary moving body 1
9 is not provided, and in this case, the cover member 1
3 in an upward rotational position, the cam shaft 16
A spring 22 is stretched between the camshaft 16 and the lifter 15 behind the camshaft 16 for positioning the camshaft 16 at the rear end of the cam groove 17.

The other configurations are substantially the same as those of the previous embodiment.

The roof window is constructed by moving the drive body 7 backward with the cover member 13 in a position facing the window opening, and by moving the cam shaft 16 and the cam groove 17 relative to each other, the lifter 15 is moved to the rear end with the rear moving body 9 as the center. The cover member 13 is rotated upward by the lever action of the lifter 15.
When the rear part is rotated upward around the front moving body 8,
The cover member 13 assumes an upwardly rotating position and functions as a spoiler, and also opens the rear part of the window opening 2 to ventilate the room. Further, when the drive body 7 is further moved backward from this upward rotational posture, the cam shaft 16 is locked to one end of the cam groove 17, and the lifter 15 is moved backward together with the drive body 7, the cover member 13 is rotated upward. The lifter 15 moves backward while maintaining its dynamic posture until the rear end of the lifter 15 reaches above the roof 1 behind the window opening 2, that is, until the midway part of the lifter 15 approaches the rear edge of the window opening 2. , the cover member 13 moves rearward, and in this state the window opening 2 is opened to a sufficient size. Then, from the time when the cover member 13 assumes the upward rotational position at the position facing the window opening,
Until it reaches the upper part of the rear roof, it remains in the same position no matter where it stops, creating a spoiler effect.

According to the present invention described in detail above, the cover member 13 is rotated upwardly through the cam devices 16, 17 and the lifter 15 by the backward movement of the driver 7, and the cover member 13 is rotated upward at the position facing the window opening 2, and the cover member 13 is rotated upwardly at the position facing the window opening 2. The cover member can be moved forward and backward with
5 has a front portion pivotally supported by the rear movable body 9 and a rear end pivotally supported by the front and rear midway portions of the cover member 13, respectively, and the cam device 1
6 and 17, the rear end rotates upward around the rear movable body 9, so that the upward rotation of the rear end of the cover member 13 is sufficiently larger than the upward rotation of the rear end of the lifter 15 due to the lever action. This makes it possible to achieve sufficient ventilation and to make the roof window more compact in the vertical direction.Moreover, the lifter 15 reaches above the roof 1 behind the window opening 2 by moving backward while the rear end rotates upward. , the cover member 13 can be moved sufficiently rearward, and the window opening 2 can be opened by the required amount.
