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 aims to prevent the interior of a vehicle from becoming narrow by making the roof window more compact, and to strengthen the holding force of the cover member in the above-mentioned upward rotational position.

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 configuration, 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 the vehicle or the like 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 was devised in view of such conventional problems, and its characteristics are that a window opening is formed in the roof of a vehicle, and guide rails are provided on both sides of the window opening. , a drive body and a front moving body are provided, which are movable back and forth along the guide rail, a front end of a cover frame supporting the cover member is pivoted to the front moving body, and a rear end of the lifter is pivoted to the cover frame. At the same time, a shaft body protruding from both sides of the front end of the lifter to be supported on both sides by the guide rail is rotatably supported by a pair of left and right rear movable bodies held by the guide rail so as to be movable back and forth, respectively, When the drive body moves forward and backward in the position facing the window opening of the cover member, the lifter is rotated downward and upward via the cam device, and the cover member is rotated through the downward and upward rotation of the cover frame linked to this. The rear part of the window opening is closed and opened, respectively, by the cover member in the downward and upward rotational positions, and by moving the driver backward from the upward rotational position of the cover member, the cover member is rotated downward and upward. The point is that the member is configured to move rearwardly and open the window opening.

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 drive body 7 includes a drive body 11 connected to a drive source such as an electric motor or a manual handle via a wire 10 as an interlocking body that can be pushed and pulled, and a pair of front and rear slides protruding from the body 11. It is composed of sliders 12, 12, and these sliders 1
2, 12 and the front/rear movable bodies 8, 9 are made of a resin material or the like and have an elliptical shape in side view, and have a substantially U-shaped cross section facing each other on the left and right sides of the guide rail 6, as shown in FIG. The guide groove 6a is fitted so as to be slidable back and forth as appropriate.

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, the rear end of each lifter 15 is pivotally supported by the rotating part of the cover frame 14, and the front end of each lifter 15 is connected to both guide grooves 6a of the guide rail 6, as shown in FIG. A shaft body 22 is inserted in a protruding manner into both guide grooves 6a, 6a from both sides of the lifter 15 so as to be supported on both sides by the lifter 15,
Both protrusions 22a, 22a of the shaft body 22 are relatively rotatably supported by a pair of left and right rear movable bodies 9, 9, which are held in the guide groove 6a so as to be movable back and forth. In this embodiment, as shown in FIG. 4, the rear movable body 9 is provided with a fitting hole 23 in its intermediate portion, into which the protrusion 22a of the shaft body 22 is fitted and supported so as to be relatively rotatable. However, the front moving body 8 and the slider 12 may also have a similar configuration. Further, a cam shaft 16 is provided on one of the drive body 7 and the midway portion of the lifter 15, and a cam groove 17 that engages with the cam shaft 16 is provided on the other, and these cam shaft 16 and cam groove 17 constitute a cam device. In the illustrated example, the front and rear camshafts 1 are attached to the drive body 7.
6a and 16b protrude laterally from the axis, and a straight front cam groove 17a and a dogleg-shaped rear cam groove 17b are formed in the middle of the lifter 15.

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
With the backward drive of the cover member, the pair of left and right rear movable bodies 9, 9 sliding on the guide rail 6 and the auxiliary movable body 19 work together to hold the lifter 15 in an upward rotating position. 13 is maintained in the upward rotational position, and the window opening 2 is opened (FIG. 2c). In addition, since the front end of the lifter 15 is supported on both sides, it has excellent strength even when a large load is applied to the lifter 15, and can prevent the lifter 15 from tilting in the left-right direction. The holding force of the member 13 in the upward rotational position can be strengthened.

Furthermore, when assembling the cover member 13 and the lifter 15, etc., the lifter 15 is connected to the guide rail 6.
Since it is held without tilting, assembly work becomes easier.

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.

As shown in FIG. 3, the guide rail 6 is installed with bolts, nuts, etc. within a rain gutter 24 provided at the lower periphery of the window opening 2, and the lower surface of the guide rail 6 is provided with appropriate intervals in the front and rear directions. A drain hole 25 is formed therein. In addition, in the center of the lower surface of the rain gutter part 24, in order to improve drainage of rainwater, etc.
An appropriately inclined drain groove 26 is formed. 2
Reference numeral 7 denotes a guide pipe for the idle side wire 10, which is arranged above and below the guide groove 28 for the drive side wire 10 of the guide rail 6.

Although a shaft body 22 is shown fitted into the front end of the lifter 15, there are two shaft bodies protruding from both sides of the front end of the lifter 15, and the shaft bodies are rotatably supported by the rear movable body 9. It may also be a holding configuration.

According to the present invention, the lifter 15 is rotated upward via the cam devices 16 and 17, and the cover member 13 is thereby rotated upward, so that the vertical engagement distance of the cam device is small. Cover member 13
This is advantageous because the rear part of the window opening 2 can be opened wide to provide sufficient ventilation in the vehicle interior. Moreover, since the engagement distance of the cam device in the vertical direction can be made small, the roof window can sometimes be made more compact in the vertical direction, which is advantageous because the problem of the vehicle interior becoming narrower can be avoided. Furthermore, since the front end of the lifter 15 that rotates the cover member 13 upward and downward is supported on both sides by the guide rail 6, the lifter 15
Even when a large load is applied to the lifter 15, it has superior strength compared to cantilever support, and can prevent the lifter 15 from tilting in the left-right direction. The holding power can be strengthened. In addition, since the lifter 15 is held on the guide rail 6 without tilting, the lifter 15
This has the advantage that the assembly work of the cover member 13 and the like is facilitated.
