[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle sashless door.

[0002]

[Prior Art]

 Sashless doors without window frames have been widely used in hard-top cars and other vehicles. FIG. 8 is a front view showing an example of a conventional sashless door 1. The door 1 is pivotally supported by a vehicle body (not shown) so as to be openable and closable. FIG. 8 is a view of the sashless door 1 as viewed from the outside of the vehicle, in which arrow X indicates the forward direction of the vehicle. FIG. 9 is an enlarged sectional view taken along line IX-IX in FIG. 8 showing the internal structure of the conventional door.

As can be seen from these figures, the door 1 comprises 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 with an open top is formed between the panels 2 and 3, and a window glass 5 is arranged therein, and the glass 5 is moved up and down in a substantially upward and downward direction indicated by an arrow A by a window regulator (not shown). It

Weather strips 6 and 7 made of an elastic material are fixed to the upper portions of the outer panel 2 and the inner panel 3, respectively, and lips of the weather strips 6 and 7 contact the outside surface and the inside surface of the window glass 5, respectively. A reference numeral 13 in FIG. 9 is a door trim that covers the inner panel 3.

Although the window glass 5 arranged between the outer panel 2 and the inner panel 3 moves up and down between the uppermost fully closed position shown by the solid line in FIG. 8 and the lowermost fully opened position shown by the chain line, Since the sashless door is not provided with a 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 reason, a glass bracket 9 is fixed to the lower part of the window glass 5, and a plurality of guide pieces 30, 31 in the illustrated example are attached to the bracket 9, and at the same time, these guide pieces 30, 31 are guided. It is fitted to the rail 11. The guide rail 11 is fixed to the door body 4. In the illustrated example, the lower portion of the rail 11 is fixed to the inner panel 3 via the bolt 12 and the mounting bracket 10, and the upper portion is fixed to the inner panel 3 by the bolt 8. It is fixed to the fixed reinforcing plate 14. As shown in FIG. 8, the guide rail 11 extends substantially vertically along the ascending / descending path of the window glass 5. The guide rail 11 has a substantially C-shaped cross-sectional shape, and guide pieces 30 and 31 supported by the window glass 5 via a 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 to guide the glass 5.

By the way, the sashless door 1 as described above has no window frame for holding the window glass 5 when the window glass 5 is raised to the fully closed position. Therefore, when the vehicle is driven at high speed in this state, The window glass 5 may swing toward the outside of the vehicle due to negative pressure. This is generally called a glass sucking phenomenon, and when such a phenomenon occurs, a sucking sound is generated. In order to prevent such sucked-out phenomenon, it is necessary to increase the support rigidity of the window glass 5. When the supporting rigidity of the window glass 5 is low, it is difficult to operate the window glass 5 smoothly up and down, especially when the vehicle is running, and it is flickering when the window glass is half-opened. Alternatively, a problem such as deterioration of sealing property when the window glass is fully closed occurs.

Therefore, as described above, a plurality of guide pieces to be fitted to the guide rail 11 are provided, and these guide pieces 30 and 31 are arranged along the longitudinal direction of the guide rail 11 with a space between each other. The guide pieces 30 and 31 increase the supporting force of the window glass 5 and increase its supporting rigidity.

As described above, at least two guide pieces 30, 31 form a support point for supporting the window glass 5 when the window glass 5 is lifted to the fully closed position or when the window glass 5 is moved up and down. However, in the conventional door 1, it is not easy to sufficiently increase the supporting rigidity of the window glass 5 only with such a guide piece. The reason is as follows.

The guide piece supports the window glass 5 at a plurality of points. In the example of FIG. 9, the two guide pieces 30 and 31 support the window glass 5 at two points. That is, by arranging the guide pieces 30 and 31 apart from each other along the guide rail 11, the effect of supporting the window glass 5 by these guide pieces 30 and 31 is enhanced. As can be seen, the larger the distance D (FIG. 9) between the guide pieces 30, 31 is, the higher the supporting rigidity of the window glass 5 can be increased.

However, if the distance D between the guide pieces 30, 31 is set too large, the window glass 5 is raised to the uppermost fully closed position, or lowered to the lowermost fully opened position. 31 or the guide rail 11 that guides this may interfere with the elements forming 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, 31 also occupy the position shown by the solid line. Assuming that the upper guide piece 30 is arranged above the state shown in FIG. 9 in order to expand D, the guide piece 30 or the upper part of the guide rail 11 for guiding the guide piece 30 may be the inner panel 3 or the reinforcing plate 14 thereof. There is a risk that it may interfere with. As described above, since it is necessary to secure a gap δ of a predetermined size or more between the guide piece 30 and the upper portion of the door body 4 to prevent these from interfering with each other, the window glass 5 is at the uppermost position. It is impossible to set the position of the guide piece 30 when it is raised to above the state shown in FIG.

On the other hand, it is possible to increase the distance D between the two guide pieces 30, 31 by shifting the position of the lowest guide piece 31 downward. However, when the lower guide piece 31 is arranged downward as described above, when the window glass 5 is lowered to the lowermost fully opened position as shown by a chain line in FIG. 9, the guide piece 31 or a guide for guiding the same. The lower portion of the rail 11 interferes with the inner panel lower portion 17 of the door body 4. That is, when the window glass 5 is lowered to the lowermost position, a gap δ of a predetermined size or more is also provided between the guide piece 31 and the inner panel lower portion 17. ₁ Therefore, it is necessary to secure the above to prevent these from interfering with each other, and therefore the position of the lowest guide piece 31 cannot be lowered unnecessarily downward.

For the above-mentioned reason, the distance between the guide pieces 30 and 31 cannot be set so large that the supporting rigidity of the window glass 5 is unavoidably reduced.

Therefore, conventionally, the support rigidity of the window glass has been increased by increasing the pressure with which the weather strips 6, 7 shown in FIG. 9 abut on the window glass 5 or by providing a window glass stabilizer (not shown). However, if such a configuration is adopted, the resistance increases when the window glass 5 is moved up and down, so that a large operating force is required and the operability of the window glass deteriorates. In addition, the size of the glass bracket 9 is increased, or the thickness of the glass bracket 9 is increased to increase the rigidity thereof, thereby improving the support rigidity of the window glass by the guide pieces 30 and 31. Not only is it difficult to sufficiently increase the supporting rigidity of the window glass 5 with such a configuration, but also the increase in the thickness and size of the glass bracket 9 inevitably increases the weight of the entire door.

[0014]

[Problems to be solved by the device]

 An object of the present invention is to provide a vehicle sashless door which can eliminate the above-mentioned conventional drawbacks and enhance the supporting rigidity of the window glass without any trouble.

[0015]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has 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 glass disposed between the outer panel and the inner panel and moved up and down by a wind regulator.

[0016]

【Example】

 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 the upper portion of the door body, and FIG. 3 is a window glass at the lowermost fully open position. It is an expanded sectional view when it is descended to. The basic structure and operation of the sashless door shown here are the same as those described above with reference to FIGS. 8 and 9, and the appearance of the door is substantially the same as that of FIG. .. Therefore, the description of the same parts as in the prior art will be omitted, and the same or similar parts as those shown in FIGS. 8 and 9 will be denoted by the same reference numerals as those in FIGS. 1 to 3. Only the points that are different from the conventional ones will be clarified below.

The first difference from the prior art is that, as shown in FIG. 4, the lowermost guide piece 31 located at the lowest position is supported so as to be able to approach or separate from the other guide piece 30. Is. As described above, at least two guide pieces are provided, and in the embodiment shown in FIGS. 1 to 4, two guide pieces 30 and 31 are provided as in the conventional example. Therefore, the lower guide piece 31 constitutes the lowermost guide piece, and the upper guide piece 30 constitutes the other guide piece.

1 to 4, a guide member 18 having a hollow inside is integrally fixed to a glass bracket 9 fixed to a window glass 5, and a slide member 19 is provided inside the guide member 18 in a longitudinal direction of a guide rail 11. It is slidably fitted along. The width of the upper portion of the guide member 18 is formed to be slightly larger than that of the lower portion thereof, and the upper portion constitutes an upper guide piece 30 slidably fitted to the guide rail 11. Further, the width of the lower part of the slide member 19 is formed to be slightly larger than that of the upper part thereof, and the lower part constitutes the lower guide piece 31 slidably fitted to the guide rail 11. 30 and 31 are arranged at intervals in the longitudinal direction of the guide rail 11. With such a configuration, the lower guide piece 31 can move toward or away 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 arranged, and the spring 20 separates the lower guide piece 31 from the upper guide piece 30. It is biased in the direction, that is, almost downward.

As shown in FIGS. 1 and 2, when the window glass 5 occupies the uppermost fully closed position, the slide member 19 pressed by the spring 20 has a claw portion protruding from the slide member itself. 21 engages with the stepped locking portion 22 formed on the guide member 18, and the slide member 19 is prevented from coming out of the guide member 18. In this way, the two guide pieces 30, 31 stand still with a predetermined distance D1. The claw portion 21 and the locking portion 22 constitute an example of a regulating means for regulating a distance D1 between the lower guide piece 31 and the upper guide piece 30, and the distance D1 at this time is as shown in the drawing. It is set to be larger than the conventional interval D shown in FIG. The lower guide piece 31 occupies a position lower than the conventional lower guide piece.

As described above, in the sashless door 1 shown in FIG. 1, since the distance D1 between the guide pieces 30 and 31 is larger than the conventional distance D, the supporting rigidity of the window glass 5 is more reliable than the conventional one. Can be increased to Therefore, when the window glass 5 is lifted to the fully closed position and the vehicle is driven at high speed, the glass is sucked out, the sealing performance is deteriorated when the window glass is fully closed, and the half-opened flap occurs. 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 its plate thickness. In addition, it is possible to reliably eliminate the conventional defects.

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 fitted to the guide rail 11 and descend along the rail 11. At this time, since the distance D1 between the 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 opened position, the slide member 19 or the lower guide piece 31 comes into contact with a stopper 23 (FIG. 3) protruding from the lower end of the guide rail 11 and stops. On the other hand, the window glass 5 and the guide member 18 fixed thereto move further downward to the lowermost position shown in FIG. 3 and stop there, so that the lower guide piece 31 is It is relatively close to the upper guide piece 30. That is, as indicated by reference numeral D2 in FIG. 3, the distance between the guide pieces 30 and 31 is narrowed.

Therefore, although the distance D1 between the guide pieces 30 and 31 when the window glass 5 is raised to the fully closed position is set larger than the conventional one, the window glass 5 is set to the fully opened position. It is possible to prevent a problem that the lower guide piece 31 hits the inner panel lower portion 17 of the door body 4 when lowered. Thus, when the window glass 5 is fully opened, the distance D2 between the guide pieces 30 and 31 is narrowed to prevent the interference between the guide piece 31 and the door body 4, and when the window glass occupies the other position, The distance D1 can be increased to increase the support rigidity of the window glass 5.

In the embodiment shown in FIGS. 1 to 4, when the above-mentioned stopper 23 lowers the window glass to the lowermost fully opened position, the distance between the lowermost guide piece and another guide piece is reduced. The stop means is configured to bring the lowest guide piece closer to the other guide pieces so as to be narrowed. Of course, the 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 gap between the lower guide piece 31 and the upper guide piece 30 is widened by the pressing action of the spring 20, as shown in FIG. Is increased.

In the embodiment shown in FIG. 5, the uppermost guide piece 130 is fixed to the upper portion of the glass bracket 9 fixed to the window glass 5, and the guide piece constituting the intermediate guide piece 32 is arranged below the uppermost guide piece 130. The member 118 is fixed, and a slide member 119 that constitutes the lowest guide piece 131 is slidably fitted to the guide member 118 along the longitudinal direction of the guide rail 11. As described above, in this embodiment, the three guide pieces 130, 32, 131 are slidably fitted to the guide rail 11. As shown in FIG. 6, the upper base 119a of the slide member 119 is slidably fitted inside the guide member 118, and the compression coil spring 120 accommodated inside the guide member 118 causes the lowermost guide piece 131 to move to another position. When the window glass is raised to the fully closed position by being biased in a direction away from the guide pieces 130 and 32, the lowermost guide piece 131 is the stepped portion formed on the base portion 119a of the slide member 119. The 121 contacts the locking portion 122 formed on the guide member 118, and the distance between the lowest guide piece 131 and the other guide pieces 130 and 32 is regulated. The inner space of the guide member 118 is covered by the lid 33 shown in FIG. 7.

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

The embodiment in which the present invention is applied to the door 1 having one guide rail 11 has been described above. As shown in FIG. 10, the sashless door 1 having a plurality of guide rails 11 and 11 is used. However, it can be applied without any problems.

Also, for a sashless door in which the guide piece is directly supported on the window glass without a glass bracket, or a sashless door configured as a roller in which the guide piece rotates with respect to the window glass, Also, the present invention can be applied without any trouble.

[0031]

[Effect of the device]

 According to the present invention, since the distance between the lowest guide piece and the other guide pieces is variable, the supporting rigidity of the window glass can be increased without the problem that the guide piece interferes with the door body.
