However, in a configuration in which the lower shield is made up of two vertical walls and the upper shield is sandwiched between the lower shield and the upper shield as in the configuration of the above-mentioned reference, the lower shield and the upper shield slide and operate. I do. At the opening of the sunroof device where dust may be entrained with the outside air, the sliding portion may be easily damaged during long-term use and may be unsightly. Also, the weight increases. In another embodiment in which the lower shield and the upper shield are joined by penetrating a pin at the front part, the lower shield is locked to the upper shield only at the front part, so that There is a possibility that the restraint in the direction is not sufficiently secured. For this reason, unless the lower shield is made of a material such as a steel plate or a resin material and is not made thick and rigid, the lower shield may vibrate due to the wind pressure of the outside air taken in from the opening and generate noise. For this reason, there is a problem that it is difficult to manufacture, and the weight of the shield becomes heavy. Also, in this case, the pins are visible from the passenger compartment, which causes a problem in the interior design.

The present invention has been made to solve these problems.
It is an object to realize a sunroof device having a lower shield that is restrained in the lateral direction without using the upper shield.

[0005]

In order to solve the above-mentioned problems, the technical measures taken in the present invention include a guide rail disposed on both sides of an opening provided in a vehicle roof, A movable panel guided by a rail to open and close the opening, and an upper shield attached to the movable panel, while being rotatably locked to the upper shield,
In a sunroof device having a lower shield slidably engaged with the guide rail, the guide rail is provided with a guide portion that allows only the movement of the lower shield in the front-rear direction. .

With such a configuration, the lower shield is restrained from moving in the lateral direction by the guide portion of the guide rail, and the upper shield and the lower shield can be moved in the front-rear direction. Therefore, the lateral movement of the lower shield is restricted without using the upper shield. As a result, it is possible to manufacture the shield firmly and inexpensively so as not to vibrate due to wind pressure or the like without increasing the thickness of the shield or employing a material having particularly excellent rigidity. In addition, even when used for a long period of time, there is no fear that the appearance will be impaired by abrasion due to sliding with dust from the outside, and a sunroof device having a shield excellent in interior design can be realized.

As described above, the mounting structure of the upper shield 5 is shown as shown in FIGS. 7 to 10. However, the upper shield 5 does not need to have a structure including all of them, and it is appropriately best in terms of the size of the upper shield 5 and the like. May be selected in combination.

Next, a method of attaching the lower shield 6 will be described with reference to FIG. 5 and FIGS. FIG. 11 is a side view of the lower shield 6. At the lower end, there are a portion having a shape for locking with the guide rail 15 and a portion having no shape for locking. The cross section of the lower shield 6 where there is no locking part is shown in FIG. Here, the lower end is fitted in the sliding groove 75 of the guide rail 15 with a slight gap in the width direction.

Further, as shown in FIG. 11, the guide rails 1 are provided at four longitudinally lower portions of the lower shield 6.
A hook claw portion 62 for locking with the hook 5 is formed. In FIG. 12, among the four hooking claws 62,
The H-H cross-sectional shape shows the engagement state of the hooking claw 62 and the sliding groove 75, but the other three places are also in the same engagement state. That is, the hook claws 62
The lower shield 6 is formed in such a shape as to protrude so as to engage with a portion of the sliding groove 75 inward of the vehicle and restrict upward movement of the lower shield 6.

Further, on the lower side of the lower shield 6, three bending claw portions 63 are positioned so as to be sandwiched between the hooking claw portions 62, and three bending claw portions 63 are provided on the side opposite to the hooking claw portions 62, that is, on the vehicle. It is provided so as to project outward. Figure 1

As described above, the lower shield 6 having the locking structure on its lower side is assembled into the sliding groove 75 by first setting the vertical wall portion 61 to the position inside the vehicle indicated by a two-dot chain line in FIG. To lock the hook claw 62 in the slide groove 75. Then, the vertical wall portion 61 is raised to the position shown by the solid line. At this time, the bending claw portion 63 is elastically deformed and pushed into the sliding groove 75. The two claws 62 and 63 are fitted in the slide grooves 75, and the lower shield 6 is firmly restrained from moving vertically and horizontally relative to the guide rail 15, and can move only in the front-rear direction. .

Next, the structure in which the upper shield 5 and the lower shield 6 are linked will be described. FIG. 15 shows the sunroof device 1
2 shows the front ends of the upper shield 5 and the lower shield 6 attached to the right of FIG. On a surface of the lower shield 6 facing the upper shield 5 side, a locking pin portion 65 is formed integrally and protrudes in the horizontal direction. On the other hand, on the upper shield 5 side, an elongated hole 58 extending in the vertical direction and having a width substantially equal to the outer diameter of the locking pin portion 65 so that the locking pin portion 65 is fitted so as to prevent play. Is provided. When the lower shield 6 is attached to the sliding groove 75 and the vertical wall 61 is raised to the position shown by the solid line in FIG. 14, the locking pin 65 is inserted into the elongated hole 58 at the same time. I have. The upper shield 5 and the lower shield 6 are configured to move in the front-rear direction by the locking pin portions 65 and the elongated holes 58. In this configuration, the locking pin portion 65 is formed integrally with the surface of the lower shield 6 on the outer side of the vehicle compartment, so that it cannot be seen by the occupant. The elongated hole 58 is also located on the back of the lower shield 6 as viewed from the occupant. As a result, an excellent interior design can be realized.

As is apparent from the above configuration of mounting the upper and lower shields 5 and 6, the upper shield 5 presses the upper shield 5 against the panel bracket 35 from the inside to the outside of the vehicle. And the lower shield 6 also extends from the inside of the vehicle to the outside of the vertical wall 6.
1 can be rotated, and the claws 62 and 63 can be assembled by pushing the claws 62 and 63 into the sliding grooves 75, so that the shields 5 and 6 can be assembled after the operation of the sunroof device is adjusted. In addition, the structure can be assembled without requiring any locking parts such as screws.

The shields 5, 6 constructed as described above
The operation of the sunroof device 10 having the following will be described. When the occupant operates a switch (not shown) for opening the sunroof device 10 in a state where the movable panel 13 in FIG. 2 is closed,
The driving device 2 operates. Then, as shown in FIG. 3, the rear end of the movable panel 13 is lowered with its front end substantially at the center of rotation. At this time, the upper shield 5 rotates with respect to the lower shield 6 and is folded. Although the center of rotation of both shields 5 and 6 does not coincide with the location where they are engaged, each shield 5 and 6 is locked by pin portion 65 and slot 58, and Is allowed in the vertical direction. Therefore, the shields 5 and 6 can be operated without imposing an excessive load.

The movable panel 13 moves backward, and the opening 21 of the vehicle starts to be opened. When the movable panel 13 moves backward, the locking pin 65 of the lower shield 6 is pushed by the elongated hole 58 of the upper shield 5, and the lower shield 6 slides in the sliding groove 75 and moves together with the movable panel 13. Since the driver retracts, the operating mechanism 3 is kept shielded from being seen by the occupant.

[0028]

As the lower shield is restrained from moving in the lateral direction by the guide portion of the guide rail, it is entangled from the opening even if it is not made of a material such as a highly rigid steel plate or a thick resin material. High rigidity can be provided so as not to vibrate or generate noise due to the wind pressure of the outside air. Further, in order to restrain the shield from moving in the horizontal direction, it is not necessary to form one of the walls with a double wall, so that it can be manufactured inexpensively and lightly. This eliminates the risk of wear and impairing the appearance.
