Description

[Detailed description of the invention] (Field of industrial application) This invention is a door that opens and closes an opening on the side of an automobile body, and in particular supports the door glass of a so-called saturationless type door that does not have a window frame. It concerns the support structure.

(Prior Art) Conventionally, as a support structure for such a door glass, a guide member extending in the vertical direction is fixedly installed inside the door body, as disclosed in, for example, Japanese Utility Model Publication No. 55-27335. On the other hand, a slider is attached to the door glass in correspondence with the guide member, and the slider is slidably fitted into the guide member, so that the door glass is supported by both of them so as to be able to move up and down. It is known what has been done. In particular, in the above-mentioned publication, play in the width direction of the vehicle body is provided between the guide member and the slider in order to smoothly move the door glass up and down, and the door glass moves within the range of this play. It is designed to be able to move in the width direction of the vehicle.

However, in the above-mentioned conventional type, it is necessary to allow the door to be opened and closed even when the door glass is in the highest position, so when the door is closed, the top edge of the door glass in the highest position is placed on the outer surface of the weather strip on the vehicle body side. It is only touched and not supported in any way. Therefore, there was a problem in that the door glass was sucked outward and vibrated, especially when driving at high speeds, resulting in large vibration noise.

(Purpose of the invention) The purpose of the invention is to allow the upper edge of the door glass at its highest position to bite into the weather strip on the vehicle body when the door is closed, without interfering with the opening/closing operation of the door. The upper end of the glass is supported by the vehicle body via a weather strip to effectively prevent the door glass from sucking out during high-speed driving.

(Structure of the invention) In order to achieve the above object, the structure of the invention is such that the door glass of the sillless type door that opens and closes the opening on the side of the vehicle body is fixedly installed in the door body in the vertical direction. and a slider that is attached to the door glass via a holder member and slidably fitted to the guide member, and is supported so as to be movable up and down, and the guide member at the highest position of the door glass. The door glass is supported so that its upper end swings in the width direction of the vehicle body by providing play in the width direction of the vehicle body between it and the slider, and a spring plate is attached to the door body corresponding to the play, and the spring plate is attached to the holder member. A spring plate is provided with an engaging portion that can be freely engaged and detached.
For this reason, when the door glass is in the open state, the engaging portion engages with the spring plate at the highest position and tilts inward to the vehicle body, and when the door is closed, the upper end is pressed against the weather strip on the vehicle body. As a result, the top edge of the door glass swings outward from the vehicle body within the above range of play, and the upper edge of the door glass in this state of swinging outward from the vehicle body is closer to the weather strip contact position of the top edge of the door glass that is tilted inward to the vehicle body. The door glass is in pressure contact with the weather strip at a high position, and the reaction force when the door is closed causes it to dig deeply into the weather strip on the vehicle body side, causing the upper edge of the door glass to pass through the weather strip and attach to the vehicle body. It is designed to be strongly supported.

(Effect of the invention) Therefore, according to the invention, when the door is closed, the door glass in the highest position is not only supported at its lower part by the guide member and the slider, but also at the upper end of the door glass. Since it is supported by the vehicle body by deeply digging into the side weather strip, it is possible to reliably prevent the door glass from being sucked out during high-speed driving, and it is possible to reduce vibration noise. Moreover, not only does it not interfere with the door opening/closing operation, but the door glass digs into the weather strip due to the reaction force when the door is closed, and no separate operating force is required for the operation. Therefore, it is possible to improve the operability. In addition, since the structure itself is simple, it can be easily implemented and has excellent practical effects.

(Example) Hereinafter, an example as a specific example of the technical means of the present invention will be described based on the drawings.

In FIGS. 1 to 3, 1 is a vehicle body, and 2 is a door opening provided on the side of the vehicle body 1. The door opening 2 has a so-called sillless type side door 3 that does not have a window frame. The front part of the door opening 2 is hinged and attached, and the door opening 2 can be opened and closed by the side door 3.

The side door 3 has a door glass 4 that can be stored in the door body 5, and can be moved upwardly from above the door body 5 by operating a conventionally known elevating drive mechanism provided on the side of the door body 5, such as a handle (not shown). It is configured to move up and down. The door body 5 is made up of an inner panel 6 and an outer panel 7, and a channel-shaped guide member 8 extending in the vertical direction is provided inside the door body 5 with its open surface 8a facing the outside of the vehicle body 1 (towards the outer panel 7). The guide member 8 is fixed to the inner panel 6 of the door body 5 via a bracket (not shown). On the other hand, at the bottom of the door glass 4, two rollers 9 and 1 are provided as sliders corresponding to the guide member 8.
0 is attached via the holder member 11,
Both rollers 9 and 10 are slidably fitted into the guide member 8 at a predetermined distance from each other vertically. Therefore, the guide member 8 and rollers 9, 10
The door glass 4 is supported so as to be movable up and down.

Between the guide member 8 and the upper roller 9 at the highest position of the door glass 4, a channel depth on the upper end side of the guide member 8 is formed deeper than other parts, so that the channel depth in the vehicle width direction is increased. A play 12 is provided, and within the range of the play 12, the upper end of the door glass 4 can swing in the width direction of the vehicle body around the lower roller 10.

Further, a mounting seat 13 is formed by bulging the inner panel 6 toward the outer panel 7 at the upper part of the inner panel 6 of the door body 5 corresponding to the play 12, and the mounting seat 13 has a downward guide. Part 8
A spring plate 14 extending toward the side is attached by bolting.

Furthermore, an engaging portion 15 is provided on the upper part of the holder member 11 and is detachable from the spring plate 14, which extends in a detour to the back side of the guide member 8 (the side facing the inner panel 6). Thus, the upper end of the door glass 4 is tilted inward into the vehicle body when the engaging portion 15 engages with the spring plate 14 at its highest position. Here, when the spring plate 14 engages with the engaging portion 15 and tilts the door glass 4 inwardly into the vehicle body, the spring plate 14 hardly undergoes elastic deformation, but in the state of engagement with the engaging portion 15, When an external force toward the outside of the vehicle body is applied to the upper end of the door glass 15, the upper end of the door glass 15 is elastically deformed toward the outside of the vehicle body.

Further, on the periphery of the door opening 2 of the vehicle body 1, a door glass 4 is provided at the highest position as shown in FIG.
Weather strips 16 are attached to the upper end and both front and rear ends, and when the door is closed, the weather strips 16 come into seal contact with the door glass 4, preventing rainwater, dust, etc. from entering the vehicle interior. It is now possible to prevent Above weather strip 1
The glass contacting surface 16a of No. 6 is slanted as a whole facing downward and outward from the vehicle body when it is not in contact with the door glass 4 (see FIG. 4a). 17 is a door trim attached to the inner panel 6 of the door body 5, and 18 is a seal rubber.

Next, the operation of the above embodiment will be explained with reference to FIG.

It is now assumed that the side door 3 is open and the door glass 4 of the side door 3 has been raised to its highest position (see FIG. 4a). in this case,
The door glass 4 includes a guide member 8, a roller 9,
10, and the engaging portion 15 of the holder member 11 engages with the spring plate 14, so that the guide member 8
and the upper roller 9 within the range of the play 12 between the upper roller 9 and the upper roller 9.

If you close the side door 3 in this state,
First, as mentioned above, the door glass 4 tilted inward into the vehicle body.
The upper end of the weather strip 16 contacts the weather strip 16 on the vehicle body side (the upper edge of the door opening 2) (see FIG. 4b).

In this case, the weather strip 16 has its glass contact surface 16a facing outward and downward and is inclined, and the upper end of the door glass 4 contacts the contact surface 16a horizontally from the outside. Of the weather strip 16, especially the corner portion 16b sandwiched between the glass contact surface 16a and the inner surface is elastically deformed.
Due to the elastic deformation of the corner portion 16b, a reaction force R directed toward the outside of the vehicle body in a substantially horizontal direction against the upper end of the door glass 4
acts. Due to this reaction force R, the holder member 11
The spring plate 14 that engages with the engaging portion 15 is elastically deformed outward from the vehicle body, and the upper roller 9 is moved from the bottom wall side of the guide member 8 toward the open surface side, so that the door glass 4 is moved away from the above-mentioned play. 12, the door glass 4 swings outward from the vehicle body around the lower roller 10, and due to the combination of this outward swing and the closing action of the side door 3, the upper end of the door glass 4 touches the glass contact surface 16a of the weather strip 16. (see Fig. 4c). When the side door 3 is completely closed, the upper end of the door glass 4, which is swung outward from the vehicle body, is lower than the contact position of the weather strip 16 at the upper end of the door glass 4, which is tilted inward from the vehicle body. Weather strip 16 at a higher position by dimension D
It comes into pressure contact with the weather strip 16 and bites deeply into the weather strip 16 (see FIG. 4d). Furthermore, here,
The dimension D is determined by the dimension of the play 12 between the guide member 8 and the upper roller 9.

On the other hand, when opening the side door 3 from such a closed state, the external force (reaction force R) acting on the upper end of the door glass 4 from the weather strip 16 gradually decreases, so that the door glass 4 recovers from the spring plate 14. Due to the force, the door glass 4 gradually tilts inward from the vehicle body centering on the lower roller 10, and when the upper end of the door glass 4 is separated from the weather strip 16, the door glass 4 is moved between the guide member 8 and the upper roller 9. The weather strip 16 returns to its original state after being tilted inward to the vehicle interior for 12 minutes, and the weather strip 16 also returns to its original state without elastic deformation, so that the side door 3 can be opened smoothly.

Further, when the door glass 4 is moved up and down by operating the handle of the elevating drive mechanism in the closed state of the side door 3, the door glass 4 is moved by the rollers 9 and 10 sliding inside the guide member 8. Therefore, it moves up and down smoothly while being supported by both of them 8, 9, and 10.

Moreover, in this case, when the door glass 4 is raised to the highest position, the upper end of the door glass 4 is exposed to the outside of the vehicle body due to contact with the weather strip 16 (glass contact surface 16a) near the highest position. Since an external force is applied to the upper end of the door glass 4, even though the engaging portion 15 of the holder member 11 engages with the spring plate 14, the upper end of the door glass 4 is not tilted inward by the spring plate 14, and the upper end of the door glass 4 is not tilted inward by the spring plate 14. Due to the elastic deformation of the plate 14 toward the outside of the vehicle body, the weather strip 16 on the vehicle body side is maintained in a state where it is swung toward the outside of the vehicle body, and at the highest position, the weather strip 16 on the vehicle body side is swung toward the outside of the vehicle body in the same manner as when the door is closed. It digs deep into the body and is pressed against it. Furthermore, when the door glass 4 is raised, a weather strip 1 is attached to the upper end of the door glass 4.
The direction of the external force acting from the weather strip 16 is different from the direction of the external force R acting on the upper end of the door glass 4 when the side door 3 is closed with the door glass 4 at its highest position. The upper end of the door glass 4 is swung outward and downward from the vehicle body by the horizontal component of this external force, which is substantially perpendicular to the glass contact surface 16a.

Therefore, in the door glass support structure described above, not only can the opening/closing operation of the side door 3 and the lifting/lowering operation of the door glass 4 be performed without any influence, but also the side When door 3 is closed, and side door 3
In either case, when the door glass 4 is raised to the highest position in the closed state, the upper end of the door glass 4 is deeply dug into the weather strip 16 on the vehicle body side, and the door glass 4 is exposed to the vehicle body through the weather strip 16. 1, the lower part of the door glass 4 is supported by the guide member 8 and the rollers 9, 10, and together with the fact that the lower part of the door glass 4 is supported by the guide member 8 and the rollers 9, 10, the door glass 4 can be strongly supported at the highest position. can do. As a result, it is possible to reliably prevent the phenomenon of suction of the door glass 4 occurring during high-speed driving, and it is possible to reduce vibration noise.

Moreover, the digging of the door glass 4 into the weather strip 16 is caused by the reaction force generated when the side door 3 is closed when the door glass 4 is in its highest position. Since no special operation or acting force is required for this purpose, operability can be improved.

Furthermore, the support structure for the door glass 4 is simpler than the conventional one, with only a spring plate 14, an engaging part 15, etc., and therefore it can be implemented at a low cost. Moreover, since it is not exposed to the outside, a good appearance can be ensured.

Furthermore, since the weather strip 16 itself on the vehicle body side does not require any changes in its shape, material, etc., the sealing function of the weather strip 16 can be maintained well.
