DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vehicle window device provided on a side surface of a vehicle.

[0002]

2. Description of the Related Art Conventionally, as a window device provided on a vehicle body side wall in a vehicle having a large vehicle body side wall area such as a so-called one-box car, a slide type and a butterfly type are known. In the formula
While it has the advantage that it can be opened and closed in half the area of the window, it has a window frame that slidably supports the window glass, and has the problem of increasing the weight,
There is a problem that a step is generated between the two window glasses and between the window glass and the window frame, which is disadvantageous in terms of appearance and wind noise, while the butterfly type has a problem.
Although a window frame is not required, the structure is simple and lightweight, and there is a problem that a step is hardly generated, which is advantageous for so-called flash surfing. As a vehicle window device that solves the above-described problem, a vehicle window device described in Japanese Utility Model Laid-Open Publication No. 4-51812 is known. In this conventional vehicle window device, rear ends of a window frame are provided above and below an opening. It is supported rotatably in the vehicle width direction, a window glass is supported slidably back and forth on this window frame, and a seal member is provided between the vehicle body and a position inside the window frame of the window glass. Because of this, when fully opened, the rear end of the window glass protrudes further outward than the rear end of the window frame, the vehicle width dimension changes significantly, and it is difficult for the driver to get a sense of the vehicle width, and the window opens. Up to two operations are a rotation operation and a slide operation, and the window frame is disposed outside the vehicle rather than the seal member. Or flash surface Of the or a problem that difficulty, there has been such a problem that it is disadvantageous in terms of weight.

In order to solve the above-mentioned problem, the present applicant has filed a Japanese Patent Application No. 7-72795.
No. vehicle window device was proposed. In this prior art, a guide bracket is provided so as to be slidable along a guide rail disposed inside a seal member, and a support bracket fixed to a window glass is connected to the guide bracket via a connection mechanism. The support bracket is configured to be movable in the vehicle width direction in accordance with the sliding of the guide bracket by the connection of the elongated hole and the pin, so that the above-described problem can be solved.

[0004]

As described above, the prior art vehicle window device of the present applicant has solved the problems of the prior art and obtained excellent effects.
When the guide rails are placed on the indoor side to create a flash surface, the support bracket and the guide bracket connect the window glass and the guide rail side while straddling the opening. And the front and rear ends interfere with each other, thereby limiting the amount of window glass sliding. In order to secure the support rigidity of the window glass, it is preferable to widen the support span by separating the support bracket back and forth, but if this support span is secured, the bracket and the opening interfere as described above. As a result, the sliding amount is reduced, and the opening area is reduced. Also,
In order to secure the sealing performance by bringing the window glass and the sealing member into close contact with each other, it is preferable that the window glass is strongly pulled into the room at a position close to the four front and rear and upper and lower corners of the window glass. The front and rear ends of the bracket and the opening interfere with each other, so that the sliding amount is reduced and a wide opening area cannot be secured. The present invention
In view of the above-described problems, the prior art vehicle window device obtains an opening area as large as possible, ensures high support rigidity of the window glass, and ensures high sealing performance. To balance
It aims to improve product quality.

[0005]

Means for Solving the Problems In order to achieve the above object, according to the first aspect of the present invention, a window opening is formed in a vehicle body side portion, and a seal member provided around the window opening. A plurality of support brackets are fixed to the inside surface of the window glass that is pressed against the window opening to close the window opening, and a guide rail is provided in the front-rear direction along the window opening at a position closer to the vehicle interior than the seal member. The guide rails are provided on the guide rails in a number corresponding to the number of the support brackets, the guide brackets being configured to move the guide rails in the front-rear direction while the movement in the vehicle width direction is restricted. The support bracket is connected by a connecting structure including an elongated hole formed on one side and a pin inserted into the elongated hole and fixed to the other side. A vehicle width direction in which the window glass is inclined in a direction closer to the inside of the vehicle toward the ride direction so that the window glass can be moved in a vehicle width direction between a seal position pressed against the seal member and a flap-out position not pressed against the seal member. When the window glass is located in the opening slide direction from the flap-out position on the guide rail, the window glass moves in the vehicle interior direction by contacting the member on the support bracket side. In the vehicle window device having a guide surface that does not perform this control when the window glass is located at the flap-out position, the guide rail is used as the guide rail. And a lower guide rail provided along the lower edge of the opening on the indoor side. And a pair of support brackets are provided at the upper edge and the lower edge of the window glass, each being separated from each other in the front-rear direction. The support brackets on the side in the open slide direction are provided at substantially the center of the upper edge and the lower edge of the window glass, while the support brackets on the side in the open slide direction are provided at the ends of the edges in the closed slide direction. . Claim 2
As described in the above, an additional portion curved in the vehicle interior direction may be formed at the end of the window glass in the open sliding direction. Further, as described in claim 3, a wire that is routed along the guide rail and driven by a motor may be connected to the guide bracket.

[0006]

When opening the window opening from the fully closed state, the guide bracket is slid with respect to the upper and lower guide rails in a predetermined opening direction. Then, the pin provided on one of the guide bracket and the support bracket moves with respect to the oblique long hole provided on the other, and the support bracket and the guide bracket are relatively displaced in the vehicle width direction. Since the movement of the bracket in the vehicle width direction is restricted by the guide rail, the support bracket is displaced in the vehicle exterior direction, whereby the window glass moves from the seal position pressed against the seal member to the flap-out position. In the structure in which the window glass is manually opened and closed when the window glass is moved from the seal position to the flap-out position, the opening operation force can be input to the window glass to move the window glass from the seal position to the flap-out position. In this case, when the window glass is moved to the flap-out position by applying an operation force to the window glass toward the outside of the vehicle body, the guide bracket is slid backward accordingly. Further, when opening and closing by a motor as described in claim 3,
When the motor is driven, the driving force is input to the guide bracket via a wire, and the guide bracket slides.

When the window glass reaches the flap-out position and the pin is moved to the end of the long hole as described above, the relative movement between the pin and the long hole is restricted, and the support bracket and the guide bracket are separated. The window glass slides along the guide rails integrally, and the window glass also slides with the slide, thereby opening the window opening. The open slide of the window glass is performed when the support bracket provided at the upper and lower edges of the window glass substantially at the center or the guide bracket connected thereto interferes with the front and rear ends of the window opening or immediately before the time. And is fully opened at this position. In the case of the present invention, since the support bracket is provided substantially at the center of the upper and lower edges of the window glass, it can be slid by approximately half the front-rear length of the window glass when it is opened. In addition, the window glass is supported at four points vertically separated from each other, and a support bracket that is supported at substantially the center of the upper and lower edges of the window glass is supported near the center of gravity of the window glass. Therefore, high support rigidity can be secured.

(Closed) When closing the window, a closing operation force is input to the guide bracket or the window glass and moved in the opposite direction to the above. At this time, in the connection structure between the support bracket and the guide bracket, the closing operation force is input in a direction in which the pin and the elongated hole are about to move relative to each other, but the movement of the support bracket in the vehicle direction is caused by the guide surface of the guide rail. The window glass moves toward the flap-out position without being displaced in the vehicle direction. When the flap-out position is reached, the guide surface no longer restricts movement in the in-vehicle direction, so that relative displacement between the pin and the long hole is made. As a result, the watertight state becomes a fully closed state. In addition, at the time of the fully closed state, according to the second aspect of the present invention, the follow-up portion formed at the end portion of the window glass in the opening slide direction abuts on the seal member while being elastically deformed outwardly of the vehicle. The window glass is strongly adhered to the sealing member. For this reason, no support bracket is provided at this end of the window glass. Although the structure cannot be pulled in the direction, the window glass is strongly adhered to the sealing member, so that high sealing performance can be obtained and supporting rigidity can be secured.

As shown in FIG. 5, the rear window RW is of a so-called butterfly type, and a window glass 28 is supported by a hinge whose front end is not shown so as to be rotatable in a horizontal direction. It is configured to open to the position indicated by the imaginary line.

Next, the operation of the embodiment will be described. a) When fully closed The front window FW according to the embodiment of the present invention is
As shown in FIG. 1, a window glass 8 is disposed on substantially the same plane as the outer surface of the vehicle body, and is pressed against and sealed to the weather strips 3a and 5a. At this time, the support brackets 9F, 9R, 10F, 10R and the guide brackets 13F, 13R, 20F, 20R are disposed at the front ends of the front and rear stroke ranges of the guide rails 11, 12, respectively. As shown in FIG. 2 (a), the guide slots 13a, 13b, 20a, 20b are arranged at the rear end positions of the guide slots 13a, and are also arranged in the fully closed grooves 11e, 12e.

B) Opening of the Window When opening the front window FW, the motor 17 is driven to rotate forward and the wires 16, 22 are pulled backward. This wire 1
6, 22 by driving the guide brackets 13F, 13
R, 20F, and 20R move rearward (in the direction of RR) on the guide rails 11 and 12, and accordingly, each guide slot 1
3a, 13b, 20a, and 20b are the respective support brackets 9;
Pins 18 fixed to F, 9R, 10F, 10R,
19, the guide slots 13a, 13b, 20a, and 20b are formed so as to be displaced outward in the vehicle toward the front.
8 and 19 are gradually displaced toward the outside of the vehicle.
Each support bracket 9F, 9 to which 8, 19 is fixed
R, 10F, and 10R are also displaced outside the vehicle. Therefore, the window glass 8 moves outward in the vehicle width direction and separates from the weather strips 3a, 5a. Note that FIG.
The position of the window glass 8 shown in (a) is called a sealing position. At this position, the window glass 8 is pressed against the weather strips 3a and 5a as shown in FIGS. On the other hand, the position where the window glass 8 has moved from the sealing position to the outside of the vehicle as shown in FIG. 2B is referred to as a flap-out position. In this flap-out position, the rear side of the window glass 8 is more open than the front side.
This is because the displacement of the front guide slots 13a, 20a in the vehicle width direction is larger than the displacement of the front guide slots 13a, 20a in the vehicle width direction.

As described above, when the pins 18, 19 have moved to the front ends of the guide slots 13a, 13b, 20a, 20b, the pins 18, 19 and each guide bracket 13F,
13R, 20F, and 20R, the pins 18 and 19 are no longer moved relative to the guide surfaces 11 and 12 of the guide rails 11 and 12, respectively.
d and 12d, the window glass 8 moves rearward along the guide rails 11 and 12 with this, and the window opening 1 is opened. By the way, the open slide of the window glass 8 is carried out by the rear upper and lower support brackets 9R,
Before the 10R collides with the rear edge of the window opening 1, the stopper is restricted at a predetermined position by a stopper (not shown), and the window glass 8 is opened and slid to this position to be restricted by the stopper. If the motor 17 is stopped due to a load increase due to the above, or if the drive of the motor 17 is stopped by a switch operation at a time before that, the opening operation described above is stopped. In FIG. 5, the position shown by the imaginary line of the window glass 8 is the fully open position, and as described above, the positions of the rear upper and lower support brackets 9R and 10R are more outward than the positions of the front upper and lower support brackets 9F and 10F. , The rear end of the window glass 8 does not interfere with the rear window RW even when the rear window RW is opened despite the formation of the additional portion 8a. That is, as compared with the case where the front upper and lower support brackets 9F and 10F are arranged by the same amount as the rear upper and lower support brackets 9R and 10R on the outside of the vehicle, the entire projecting amount to the outside of the vehicle is made smaller to achieve the fully closed state as much as possible. While keeping the vehicle width unchanged, the rear end position of the window glass 8 when fully opened can be disposed outside to prevent interference with the rear window RW.
As described above, the window glass 8 is slid open just before the rear upper and lower support brackets 9R and 10R interfere with the rear end of the window opening 1, but in the present embodiment. , Rear upper and lower support bracket 9
Since R and 10R are provided at the center positions of the upper and lower edges of the window glass 8, the brackets 9R and 10R are more rearward (open) than those provided at the rearward position than in the present embodiment.
A large opening can be obtained by increasing the sliding amount, while the upper and lower brackets 9F. A large supporting stiffness can be obtained by securing a wide interval L1 and L2 with the 10F. That is, in the present embodiment, it is possible to achieve both securing the support rigidity and securing the wide opening.

C) When closing the window When closing the window from the above-mentioned front open window FW, the motor 17 is driven in the reverse direction to push out the wires 16 and 22, and the guide brackets 13F, 13R, 20F,
20R moves forward on each of the guide rails 11 and 12, and accordingly, each support bracket 9F, 9R, 10F, 10
R also moves forward, and the window glass 8 moves forward. At this time, the pins 18, 19 are connected to the respective guide slots 13a, 1a.
3b, 20a, and 20b obliquely contact with each other, a component force is generated in the pins 18 and 19 in the vehicle interior direction.
The guide brackets 8, 19 are in contact with the guide surfaces 11 d, 12 d, and are restricted from moving in the vehicle interior.
F, 13R, 20F, 20R are also guide rails 11, 1
2 restricts movement in the vehicle width direction, the pins 18 and 19 are connected to the respective guide brackets 13F, 13R and 20.
F, 20R, without being moved relative to the guide slots 13a, 13b, 20a, 20b.

When the window glass 8 reaches the flap-out position, the pins 18 and 19 are pulled by the retraction guide member 2.
4 and is guided by the curved surface of the guide claw 24a in the vehicle interior direction, so that the pins 18 and 19
With respect to each of the guide brackets 13F, 13R, 20F, and 20R, the guide brackets 13A, 13B, 20A, and 20B move inward while performing a relative movement of moving the guide slots 13A, 13B, 20A, and 20B backward.
Thereby, the window glass 8 moves to the sealing position and is pressed against the weather strips 3a, 5a. At this time, the window glass 8 is deformed elastically in the vehicle exterior direction at the rear end portion 8a provided at the rear end thereof.
a, 5a, so that the seal is reliably sealed by the restoring force of the deformation. That is, in the present embodiment, no support bracket is provided at the rear end of the window glass 8, and this rear end is provided with the pins 18, 19 and the guide slots 13a,
Although it cannot be pulled into the vehicle interior due to the relative displacement with 13b, 20a, 20b, high sealing properties and support rigidity can be ensured by the restoring force due to the elastic deformation of the follow-in portion 8a.

As described above, in the vehicle window device of the present embodiment, when the window glass is opened, the window glass 8 moves from the sealing position to the flap-out position and then moves rearward in parallel, so that the wide opening is provided. While the vehicle width hardly changes. In addition, each guide bracket 13
F, 13R, 20F, 20R to each guide rail 11, 1
In order to perform the flap-out and the backward slide simply by moving the guide bracket 13 backward along
The motors can be electrically operated only by connecting the F, 13R, 20F, 20R to the wires 16, 22 driven by the motor 17, and the motorization is easy. In addition, guide brackets 13F, 13R, 20
F, 20R and the guide brackets 13F, 13
Guide rails 11 and 12 supporting R, 20F and 20R
Is provided on the inner side of the sealing surface, so that the installation work of the motor 17 and the wires 16 and 22 is easy, which also facilitates the electric operation. It is only necessary to provide a recess for arranging the window glass 8 inside the outer plate, which is advantageous in press molding. Further, the guide rails 11 and 12 can be arranged so as not to be seen from outside and inside the vehicle. Looks good. Further, in the present embodiment, since the curtain rail portion 11c is formed integrally with the upper guide rail 11 by extrusion, the arrangement can be made compact and the cost can be reduced.

Further, in the present embodiment, the support bracket 9 for the front guide brackets 13F and 20F is provided.
F, 10F, supporting brackets 9R, 1R for guide brackets 13R, 20R on the rear side of the displacement amount in the vehicle width direction.
Since the displacement amount in the vehicle width direction of 0R is set to be larger, the rear end of the window glass 8 at the time of full opening is set as far away from the vehicle as possible while keeping the total flip-out amount small and minimizing the change in vehicle width due to opening and closing. To prevent interference with the rear window RW. In particular, in the present embodiment, the additional portion 8a is provided at the rear end of the window glass 8, and the rear end of the window glass 8 and the rear window RW easily interfere with each other when fully opened. Has become more effective.

Further, in the present embodiment, the rear upper and lower support brackets 9R and 10R are respectively
And the front support brackets 9F and 10F are provided at the front ends of the upper and lower edges of the window glass, respectively, so that the front support brackets 9F and 10F are fully closed when fully opened. The rear upper and lower support brackets 9R and 10R do not move rearward from the positions of the rear upper and lower support brackets 9R and 10R.
However, in a structure that does not move behind the rear end of the window opening 1, it is possible to obtain as large an opening area as possible while securing the support rigidity of the window glass 8. That is, in the present embodiment, it is natural that a wider spacing between the front support brackets 9F, 10F and the rear support brackets 9R, 10R provides higher support rigidity and higher sealing performance. When the distance between the front support brackets 9F, 10F and the rear support brackets 9R, 10R is narrowed, the open slide distance becomes large. The opening area can be increased, but the support rigidity and the sealing performance decrease.
