BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sashless door for an automobile.

[0002]

2. Description of the Related Art Sashless doors without a window frame have been widely used in hardtop vehicles and the like. FIG. 8 is a front view showing an example of a conventional sashless door 1. This door 1 is pivotally supported on a vehicle body (not shown) so as to be openable and closable. FIG. 8 is a view when the sashless door 1 is viewed from the outside of the vehicle. In this figure, an arrow X indicates a forward direction of the vehicle. FIG. 9 shows the internal structure of a conventional door.
IX-IX line enlarged sectional view of FIG.

As can be seen from these figures, a door 1 has a door body 4 having an outer panel 2 located on the outside of the vehicle and an inner panel 3 located on the inside of the vehicle. The parts are integrated by hemming. A space having an open upper portion is formed between the panels 2 and 3, and a window glass 5 is disposed in the space.

Weather strips 6 and 7 made of an elastic material are fixed to upper portions of the outer panel 2 and the inner panel 3, respectively, and their lips are in contact with the outer surface and the inner surface of the window glass 5, respectively. 9 is a door trim that covers the inner panel 3.

A window glass 5 disposed between the outer panel 2 and the inner panel 3 moves up and down between a top fully closed position shown by a solid line in FIG. 8 and a bottom fully open position shown by a chain line. Since the sashless door has no window frame, the window glass 5 cannot be guided by the window frame when the window glass 5 is moved up and down. For this purpose, a glass bracket 9 is fixed to the lower part of the window glass 5, a plurality of guide pieces 30, 31 in the illustrated example are attached to the bracket 9, and these guide pieces 30, 31 are attached to guide rails. 11. The guide rail 11 is fixed to the door body 4. In the illustrated example, the lower part of the rail 11 is fixed to the inner panel 3 via the bolt 12 and the mounting bracket 10, and the upper part is fixed to the inner panel 3 by the bolt 8. Is fixed to the reinforcing plate 14. As shown in FIG. 8, the guide rail 11 extends substantially vertically along a vertical path of the window glass 5. The guide rail 11 has a substantially C-shaped cross-sectional shape, and guide pieces 30, 31 supported by the window glass 5 via the glass bracket 9 are slidably fitted therein.
When the window glass 5 moves up and down, the guide pieces 30 and 31 move along the guide rails 11 and guide the glass 5.

Incidentally, the sashless door 1 as described above
When the windowpane 5 is raised to the fully closed position, there is no window frame for holding the windowpane 5, and when the vehicle is driven at high speed in this state, the windowpane 5 swings outward due to the negative pressure. There is a risk. This phenomenon is generally called a glass sucking phenomenon, and when such a phenomenon occurs, a sucking sound is generated. In order to prevent such a phenomenon of being sucked out, it is necessary to increase the holding rigidity of the window glass 5. When the holding rigidity of the windowpane 5 is low, particularly when the windowpane 5 is raised and lowered during traveling of an automobile, it is difficult to smoothly operate the windowpane 5 up and down, and when the windowpane is half-open, the glass flaps. Or, a problem such as a decrease in sealing performance when the window glass is fully closed occurs.

Therefore, as described above, a plurality of guide pieces to be fitted to the guide rails 11 are provided, and these guide pieces 30 and 31 are arranged at intervals from each other along the longitudinal direction of the guide rails 11. Guide piece 30,
31 increases the holding rigidity of the window glass 5.

As described above, the at least two guide pieces 30, 31 serve to increase the holding rigidity of the window glass 5 when the window glass 5 is lifted to the fully closed position or when the window glass 5 is raised and lowered. However, in the conventional door 1, it was not easy to sufficiently increase the holding rigidity of the window glass 5 only with such a guide piece. The reason is as follows.

Each guide piece 3 supported by the window glass 5
0, 31 are spaced apart from one another along the guide rail 11, whereby the guide pieces 30, 3
1 increases the effect of holding the window glass 5. As can be seen, the distance D between the guide pieces 30, 31 (FIG. 9)
, The holding rigidity of the window glass 5 can be increased.

However, if the distance D between the guide pieces 30, 31 is too large, when the window glass 5 is raised to the uppermost fully closed position or lowered to the lowermost fully open position, the guide pieces 30, 31 are lowered. There is a possibility that the guide rails 31 or the guide rails 11 for guiding them may interfere with the elements constituting the door body 4. That is, when the window glass 5 is lifted to the uppermost fully closed position as shown by the solid line in FIG. 9, the guide pieces 30 and 31 also occupy the position shown by the solid line. If the upper guide piece 30 is disposed above the state shown in FIG. 9 in order to expand the guide piece, the guide piece 30 or the upper portion of the guide rail 11 that guides the guide piece 30 interferes with the inner panel 3 or the reinforcing plate 14 thereof. Inevitable. As described above, it is necessary to secure the gap δ of a predetermined size or more between the guide piece 30 and the upper part of the door body 4 to prevent them from interfering with each other. The position of the guide piece 30 when ascending cannot be set higher than the state of FIG.

On the other hand, by shifting the position of the lowermost guide piece 31 downward, both guide pieces 30,
It is also conceivable to increase the interval D of 31. However,
When the lower guide piece 31 is disposed below, when the window glass 5 is lowered to the lowermost fully open position as shown by a chain line in FIG. 9, the guide piece 31 or the guide rail 11 for guiding the same is lowered. The lower part of the door body 4
Interferes with the lower part 17 of the inner panel. That is,
When lowering the window glass 5 to the position of the lowermost and also between the guide piece 31 and the inner panel lower 17, necessary to prevent these interference to secure a predetermined or more the size of the gap [delta] ₁ Therefore, the position of the lowermost guide piece 31 cannot be lowered unnecessarily.

For the reasons described above, both guide pieces 3
The interval between 0 and 31 cannot be set too large,
This inevitably reduced the holding rigidity of the window glass 5.

Therefore, conventionally, the holding rigidity of the window glass has been increased by increasing the pressure at which the weather strips 6, 7 shown in FIG. 9 abut the window glass 5, or by providing a window glass stabilizer (not shown). When such a configuration is adopted, the resistance of the window glass 5 when the window glass 5 is raised and lowered is increased, so that a large operation force is required, and the operability of the window glass is reduced. It is also performed to increase the size of the glass bracket 9 or to set the plate thickness to be large and to increase the rigidity of the glass bracket 9 to improve the rigidity of holding the window glass by the guide pieces 30 and 31. It is not only difficult to sufficiently increase the holding rigidity of the window glass 5 only by the configuration, but also the problem that the weight of the entire door increases by increasing the thickness and size of the glass bracket 9 is inevitable.

[0014]

SUMMARY OF THE INVENTION An object of the present invention is to provide a sashless door for an automobile which eliminates the above-mentioned drawbacks and can increase the rigidity of holding a window glass without hindrance.

[0015]

In order to achieve the above object, the present invention provides a door body having an outer panel on the outside of the vehicle and an inner panel on the inside of the vehicle, a window regulator disposed between the outer panel and the inner panel. And a guide rail fixed to the door body and extending substantially vertically along the vertical path of the window glass, and supported by the window glass and fitted to the guide rail to raise and lower the window glass. At least two guide pieces that sometimes move along the guide rails, the guide pieces being spaced from one another along the length of the guide rails. The lowermost guide piece located below is connected to another guide located above and fixed to the window glass. Pressurizing means for movably supporting the base in a direction approaching or separating along the longitudinal direction of the guide rail, and urging the lowermost guide piece in a direction to separate from the other guide pieces; Regulating means for regulating the position of the lowest guide piece with respect to the other guide piece so that the distance between the lowest guide piece and the other guide piece urged by the pressurizing means does not become larger than the maximum gap And a stopper that abuts on the lowest guide piece so that the distance between the lowest guide piece and another guide piece is reduced when the window glass is lowered to the lowest fully open position. We propose a car sashless door.

[0016]

FIG. 1 is a sectional view similar to FIG. 9, showing an example of a sashless door according to the present invention, FIG. 2 is an enlarged sectional view of an upper portion of a door body, and FIG. It is an expanded sectional view when it is lowered to the fully open position. The basic configuration and operation of the sashless door shown here are the same as those described above with reference to FIGS. That is, the sashless door 1 of the automobile of the present embodiment is also disposed between the outer panel 2 and the inner panel 3 and the door body 4 having the outer panel 2 on the outside and the inner panel 3 on the inside, and is not shown. A window glass 5 raised and lowered by a window regulator, a guide rail 11 fixed to the door body 4 and extending substantially vertically along a vertical path of the window glass 5, supported by the window glass 5 and fitted to the guide rail 11 At least two guide pieces 3 that move along the guide rail 11 when the window glass 5 moves up and down
0, 31 and these guide pieces 30, 31
Are spaced from each other along the longitudinal direction of the guide rail 11. The appearance of the door is not substantially different from FIG. Therefore, the same or similar portions as those shown in FIGS. 8 and 9 are denoted by the same reference numerals in FIGS. 1 to 3 as those in FIGS. Is omitted.

A first point different from the prior art is that the lowermost guide piece 31 located at the lowest position as shown in FIG.
However, this is a point that it is movably supported in a direction approaching or separating along the longitudinal direction of the guide rail 11 with respect to another guide piece 30 located above this. As described above, at least two guide pieces are provided. In the embodiment shown in FIGS.
Since two guide pieces 30, 31 are provided as in the conventional example, the lower guide piece 31 constitutes the lowermost guide piece, and the upper guide piece 30 constitutes another guide piece. ing.

1 to 4, a guide member 18 having a hollow inside is integrally fixed to a glass bracket 9 fixed to the window glass 5, and a slide member 19 is provided inside the guide member 18.
Are slidably fitted along the longitudinal direction of the guide rail 11. The upper portion of the guide member 18 is formed to have a width slightly larger than that of the lower portion, and the upper portion corresponds to the guide rail 11.
The upper guide piece 30 is slidably fitted to the upper guide piece 30. Thus, the other guide pieces 30 located above the lowermost guide piece 31 are fixed to the window glass 5. The lower part of the slide member 19 also
The width is formed slightly larger than the upper part, and the lower part constitutes the lowermost lowermost guide piece 31 which is slidably fitted to the guide rail 11, and these guide pieces 30, 31 are formed by the guide rails. 11 are spaced apart from each other in the longitudinal direction. With such a configuration, the lower guide piece 31 can move in a direction to approach or separate from the upper guide piece 30.

Inside the guide member 18, a compression coil spring 20, which is an example of a pressurizing means, is provided. This spring 20 separates the lowermost guide piece 31 from the other upper guide piece 30. In this direction, that is, almost downward. As described above, the sashless door 1 of the illustrated vehicle is the lowermost guide piece 3.
It has a pressurizing means composed of a compression coil spring 20 for urging the member 1 away from the other guide piece 30, and further includes a regulating means described below.

When the window glass 5 occupies the uppermost fully closed position as shown in FIGS. 1 and 2, the slide member 19 pressed by the spring 20 is provided with a claw projecting from the slide member itself. 21 engages with a step-like locking portion 22 formed on the guide member 18, thereby preventing the slide member 19 from falling out of the guide member 18. In this way, the two guide pieces 30, 31 stand still while maintaining the predetermined interval D1. The claw portion 21 and the locking portion 22 are connected to the lowermost guide piece 3 urged by a pressurizing means including a spring 20.
An example of a restricting means for restricting the position of the lowermost guide piece with respect to the other guide piece 30 so that the distance D1 between the first guide piece 30 and the other guide piece 30 located above it does not become larger than the maximum distance. I do. The interval D at this time
1, that is, the maximum interval is the conventional interval D shown in FIG.
It is set larger than. The lowest guide piece 3
1 occupies a position lower than the conventional lower guide piece.

As described above, in the sashless door 1 shown in FIG. 1, the distance D1 between the two guide pieces 30, 31 is determined.
Is larger than the conventional distance D, so that the holding rigidity of the window glass 5 can be reliably increased as compared with the related art. Therefore, when the vehicle is driven at high speed with the windowpane 5 raised to the fully closed position, the glass is sucked out, the sealing performance when the windowpane is fully closed, and the windowpane is half-opened with fluttering. This can be prevented or effectively suppressed. Accordingly, it is not necessary to press the weather strips 6 and 7 against the window glass 5 with an extremely large force, and it is not necessary to form the glass bracket 9 in a particularly large size or to increase the thickness thereof. In addition, conventional problems can be reliably removed.

When the window glass 5 at the fully closed position is lowered by a window regulator (not shown), the guide pieces 30 and 31 are lowered along the guide rail 11 while being fitted to the guide rail 11. At this time, since the distance D1 between the two guide pieces 30 and 31 is set to be large, the stability of the glass during operation of the window glass is also enhanced.

When the window glass 5 approaches the lowermost fully open position, the slide member 19 or the lowermost guide piece 3 is opened.
1 is a stopper 2 projecting from the lower end of the guide rail 11
3 and stops. In contrast, window glass 5
And the guide member 18 fixed thereto moves further downward to reach the lowermost position shown in FIG. 3 and stops there, so that the lowermost lower guide piece 31 is connected to the other guide piece 30. Approach relatively. That is, as shown by reference numeral D2 in FIG. 3, the interval between the two guide pieces 30, 31 is reduced.

For this reason, the distance D between the two guide pieces 30, 31 when the window glass 5 is raised to the fully closed position.
1 is set larger than before, but when the window glass 5 is lowered to the fully open position, the lowermost guide piece 31
Can be prevented from hitting the lower part 17 of the inner panel of the door body 4. Thus, when the window glass 5 is fully opened, the distance D2 between the two guide pieces 30, 31 is reduced to reduce the distance between the guide pieces 3, 31.
When the window glass occupies other positions, interference between the door glass 1 and the door main body 4 is prevented, and the holding rigidity of the window glass 5 can be increased by increasing the distance D1.

As described above, when the window glass 5 is lowered to the lowermost fully open position, the lowermost guide piece 31 and the other guide pieces 3 are attached to the sashless door 1 of the illustrated vehicle.
A stopper 23 is provided so as to abut the lowermost guide piece so as to reduce the interval between the guide pieces. Stopper 23
May be provided on the door body 4 such as the inner panel 3, for example.

When the window glass 5 is raised again, the interval between the lower guide piece 31 and the upper guide piece 30 is widened as shown in FIG. Is enhanced.

In the embodiment shown in FIG.
The uppermost guide piece 130 is fixed to the upper part of the glass bracket 9 fixed to the lower end, and a guide member 118 constituting the intermediate guide piece 32 is fixed to a lower part thereof. Of the guide piece 131 of the guide rail 1
1 are slidably fitted along the longitudinal direction. Thus, in this embodiment, the three guide pieces 130, 3
2 and 131 are slidably fitted on the guide rail 11. As shown in FIG. 6, the base 119a at the upper part of the slide member 119 is slidably fitted inside the guide member 118, and the lowermost guide piece 131 is moved by the compression coil spring 120 housed therein. The lowermost guide piece 131 is formed on the base portion 119a of the slide member 119 when the window glass is raised to the fully closed position. The stepped portion 121 abuts on the locking portion 122 formed on the guide member 118, and the distance between the lowermost guide piece 131 and the other guide piece 32 above it is regulated. Guide member 118
Is covered by the lid 33 shown in FIG.

The other structure of this embodiment and its operation are substantially the same as those of the previous embodiment, and therefore, detailed description thereof will be omitted.

Although the embodiment in which the present invention is applied to the door 1 having one guide rail 11 has been described above, the sashless door 1 having a plurality of guide rails 11 as shown in FIG. However, the present invention can be applied without any problem.

The present invention is also applicable to a sashless door in which a guide piece is directly supported on a window glass without a glass bracket, or a sashless door in which the guide piece is configured as a roller which rotates with respect to the window glass. Can be applied without hindrance.

[0031]

According to the present invention, since the distance between the lowermost guide piece and the other guide pieces is variable, the rigidity of the window glass can be increased without the guide piece interfering with the door body. Can be.
