A device that makes the opening portion of the roof open and slides the lid forward to seal the opening portion of the roof is generally referred to as a sunroof device, and is installed in many automobiles.
[0003]
In the sunroof device, left and right guide rails are disposed along the lower portions on both sides of the opening provided in the roof, and a drive shoe is slidably fitted to the guide rail, and the drive shoe is interposed via an elevating mechanism or the like. When both sides of the lid are supported and the drive motor is driven from the fully closed state of the lid and the drive shoe slides backward through the drive cable, the lifting mechanism is first actuated to lower the lid and then move backward. When the drive shoe slides forward by driving the drive motor from the fully open state by sliding, the lid slides forward, and then the lifting mechanism is actuated to raise the lid so that the lid And a fully closed state in which the opening is closed in a row.
[0004]
In the sunroof device as described above, the drain plate that receives water leakage at the rear edge of the roof opening must be configured to move in the front-rear direction together with the lid. Conventionally, the drain plate is fixed to the lid side. In general, a type in which the drain plate is slidably fitted to the guide rail and supported is used.
[0005]
[Problems to be solved by the invention]
Among the methods for assembling the drain plate described above, the type in which the drain plate is slidably fitted to the guide rail is provided with drain shoes on the left and right sides of the drain plate, and the left and right drain shoes are attached to the left and right guide rails. Each drain shoe is slidably fitted, and the drain shoe and the lid member are connected by a connecting member, and the drain plate is also slid in the front-rear direction as the lid slides in the front-rear direction.
[0006]
As described above, in the sunroof device that involves the movement of the lid in the vertical direction during the opening and closing operation, the position of the drain plate in the front-rear direction does not have to be greatly shifted while the lid is moving in the vertical direction. A configuration is adopted in which the lid bracket fixed to the lower portions on both sides and the drain shoe are connected by a connecting member, and a press-worked product of a steel plate is generally used as the connecting member.
[0007]

[0020]
In the above configuration, the opening / closing operation mode of the lid 6 will be described with reference to FIGS.
[0021]
As shown in FIG. 1A, in the fully closed state in which the weather strip 6a on the periphery of the lid 6 is in elastic contact with the peripheral flange of the roof opening and the lid 6 is flush with the roof 1 to close the opening 1a. The wedge pin 42c at the rear end of the front link 42 is located at the rear end portion of the groove portion 41a of the front wedge member 41, and the pin 52a at the front end portion of the rear link 52 and the pin 52b at the intermediate portion are front guide grooves of the rear wedge member 51. 51a is located at the front end of the rear guide groove 51b. In this fully closed state, the drain plate 8 is held at a position along the lower rear edge of the roof opening 1a and leaks from the elastic contact portion between the weather strip 6a on the rear edge of the lid 6 and the rear edge flange of the opening 1a. Water is received by the drain plate 8.
[0022]
When a driving mechanism (not shown) is driven in the lid opening direction from this fully closed state, first, the lid 6 cannot move backward, so the driven shoe 43 and the drain shoe 9 cannot move backward, and only the driving shoe 3 moves backward. . With the rearward movement of the drive shoe 3, the wedge pin 42c of the front link 42 relatively moves forward in the horizontal groove portion of the groove portion 41a of the front wedge member 41 as shown in FIG. The rear link 52 of the elevating mechanism 5 moves rearward together with the drive shoe 3, and the pins 52a and 52b at the front end portion and the intermediate portion move rearward in the front guide groove 51a and the rear guide groove 51b of the rear wedge member 51, respectively. The rear link 52 pivots downward about the pin 52c at the rear end and lowers the rear portion of the lid 6 due to the rearward rising inclination of the rear guide groove 51b. During this time, the wedge pin 42c of the front elevating mechanism 4 only moves relatively forward in the horizontal groove portion of the groove portion 41a of the front wedge member 41. Therefore, the front portion of the lid 6 hardly moves and only the rear portion of the lid 6 is moved. The rear weather strip 6a slides on the rear edge flange of the opening 1a and moves downward.
[0023]
When the drive shoe 3 further moves rearward, as shown in FIGS. 1C and 1D, the rear link 52 further moves downward around the pin 52c while moving rearward to further move the rear portion of the lid 6. At the same time, the wedge pin 42c of the front link 42 moves further forward in the groove portion 41a of the front wedge member 41 and enters the inclined groove portion that rises forward from the horizontal groove portion, so that the front link 42 becomes the intermediate pin 42b.

During this time, the drain plate 8 does not move in the front-rear direction but is held at a position along the lower rear edge of the opening 1a.
[0024]
In this lowest position, the wedge pin 42c of the front link 42 is located at the front end of the front upward inclined groove portion of the groove portion 41a, and the front end portion and intermediate pins 52a and 52b of the rear link 52 are the front guide groove 51a and the rear guide. Located at the rear end of the groove 51b, the front elevating mechanism 4, the rear elevating mechanism 5, the lid 6 and the drain plate 8 move rearward together with the drive shoe 3, and are fully opened as shown in FIG. Then, the lid 6 is opened.
[0025]
When the drive mechanism (not shown) is driven in the opposite direction to that when the lid is opened and the drive shoe 3 slides forward from the fully open state of the lid shown in FIG. 4 and 5 move forward together with the lid 6, the drain plate 8 also moves forward together, and reaches the front end position shown in FIG. 1 (D), and the driven shoe 43 is provided with a stopper portion 2 a provided on the guide rail 2. I was detained to move forward. When the driven shoe 43 hits the stopper portion 2a, the drain plate 8 is in a predetermined position along the lower portion of the rear edge of the opening 1a.
[0026]
When the drive shoe 3 further slides forward from here, the forward movement of the driven shoe 43 is restrained by the stopper portion 2a as described above, so that the wedge pin 42c is relatively moved in the groove portion 41a of the front wedge member 41. The front link 42 rotates clockwise around the pin 42b due to the forwardly rising inclination of the groove portion 41a, and the front portion of the lid 6 via the pin 42a as shown in FIG. 1C. To raise. 1D to FIG. 1C, the rear link 52 moves forward with respect to the rear wedge member 51, so that the pins 52a and 52b move in the front guide groove 51a and the rear guide groove 51b, respectively. Moving forward, the rear link 52 pivots upward about the pin 52c at the rear end and lifts the rear portion of the lid 6 upward.
[0027]
Further, when the drive shoe 3 slides forward, the wedge pin 42c of the front elevating mechanism 4 enters the horizontal groove portion of the groove portion 41a of the front wedge member 41 and is relatively moved as shown in FIGS. The rear portion of the lid 6 stops moving upward, and the pins 52a and 52b of the rear elevating mechanism 5 continue to move forward in the front guide groove 51a and the rear guide groove 51b, respectively. The rear part of the lid 6 is raised to a fully closed state, and the closing operation of the lid 6 is completed.
[0028]
As described above, the lid opening / closing mechanism is configured to operate the lid in the vertical direction by sliding only the driving shoe without sliding the driven shoe, and adopts a configuration in which the driven shoe and the drain shoe are coupled. As a result, a simple rod material can be used as a connecting member between the driven shoe and the drain shoe, and it can be assembled by almost one-touch operation by simply pushing the rod material. The position can be easily adjusted by adjusting the position of the collar to the rod material.
[0029]

However, the connection structure of the driven shoe 43 and the drain shoe 9 by the connecting member 10 made of a rod material is as described above. For example, the horizontal shaft portion 10a is bent at the rear end portion of the rod material, and the horizontal shaft portion 10a and the rod material in the vicinity thereof are pushed into the horizontal hole and the vertical hole provided in the drain shoe 9 through the slit. Alternatively, the collar 10b may be fixed to the front portion of the rod material, and the collar 10b may be fitted into a notch provided in the driven shoe 43 and coupled. Alternatively, the front shaft portion 10a may be bent at the front end portion and the rear end portion of the rod material, and the front and rear horizontal shaft portions 10a may be fitted into the driven shoe 43 and the drain shoe 9 and coupled. The collar 10b may be caulked and fixed to the front part and the rear part of the material, and the front and rear collars 10b may be fitted and joined in notches formed on both the driven shoe 43 and the drain shoe 9, respectively. Also in these cases, disconnection can be prevented by adopting a configuration in which the slit is elastically expanded and pushed.
