Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a door that opens and closes an opening on the side of an automobile body, and in particular supports a door glass in 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. What has been done is known. 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.

On the other hand, in order to prevent such vibration of the door glass, for example, as disclosed in JP-A-56-159482, an elastic body that contacts the inside of the guide member at the lower end of the door glass may be provided. There is. However, in this case, since the elastic body is in contact with the contact guide member, a large frictional resistance is generated when the door glass is raised and lowered, making it impossible to smoothly raise and lower the door glass. In addition, the elastic body must be attached to the lower end of the door glass while the elastic body is in contact with the inside of the guide member.
It also has the disadvantage of being quite cumbersome.

(Object of the Invention) The object of the present invention is to raise and lower the upper end of the door glass at the highest position when the door is closed, without causing any hindrance to the opening/closing operation of the door or the vertical movement of the door glass, and while simplifying the assembly. By cutting into the weather strip on the vehicle body side, the upper end of the door glass is supported by the vehicle body via the weather strip, and the phenomenon of the door glass being sucked out during high-speed driving is effectively prevented. It is something.

(Structure of the Invention) In order to achieve the above-mentioned object, the structure of the present 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. A channel-shaped guide member extending in the direction of the guide member and a slider attached to the door glass and slidably fitted in the guide member support the guide member so as to be movable up and down. By forming the channel depth of the guide member deeper than other parts and continuously between the slider and the slider, play in the width direction of the vehicle body is provided, so that the upper end of the door glass swings in the width direction of the vehicle body. Support as follows. Further, the slider is divided into two parts, an inner and an outer part, and between the inner part and the outer part of the slider, both the inner and outer parts of the slider are inserted in the vehicle width direction at the highest position of the door glass. The door glass is provided with spring means that applies a spring force in a direction that always tilts the door glass inward into the vehicle body when it is expanded. Therefore, when the door is open, the door glass is tilted inward from the vehicle body at its highest position, and when the door is closed, the upper end presses against the weather strip on the vehicle body, allowing it to move outward within the range of play. The upper edge of the door glass, which is swung outward from the car body, is in pressure contact with the weather strip at a higher position than the weather strip contact position at the top edge of the door glass, which is tilted inward from the car body. The upper end of the door glass is firmly supported by the vehicle body through the weather strip by deeply biting into the weather strip on the vehicle body side by the reaction force when the door is closed.

(Effects of the Invention) Therefore, according to the present 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 the upper end of the door glass is supported by the vehicle body. 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. Furthermore, since the spring means is located between the inner and outer parts of the slider and does not come into direct contact with the guide member, the door glass can be moved up and down smoothly. Furthermore, since the structure is simple and the assembly is easy, it can be easily put into practice and has excellent practical effects.

(Example) Hereinafter, an example as a specific example of the technical means of the present invention will be described in detail 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 sashless 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.

Then, between the upper roller 9 of the guide member 8 at the highest position of the door glass 4, the channel depth on the upper end side of the guide member 8 is deeper than other parts, and is continuous so that there is no step. As a result, a play 12 in the width direction of the vehicle body 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 centering on the lower roller 10. Further, the roller portion 9a of the upper roller 9 is divided into an inner portion 9c and an outer portion 9d on a plane perpendicular to the axis of the shaft portion 9b, and between the two portions 9c and 9d, both portions are separated. The door glass 4 is always kept inside the vehicle body with both portions 9c and 9d expanded in the width direction of the vehicle body within the guide member 8 in the direction in which the portions 9c and 9d are separated within the guide member 8, that is, at the highest position of the door glass 4. A spring 13 serving as a spring means for applying a spring force in the tilting direction is interposed in a compressed state surrounding the outer periphery of the shaft portion 9b.

On the other hand, at the periphery of the door opening 2 of the vehicle body 1, there is a door glass 4 at the highest position as shown in FIG.
A weather strip 14 is attached to the upper end and both front and rear ends, and when the door is closed, the weather strip 14 comes into seal contact with the door glass 4 to prevent rainwater, dust, etc. from entering the vehicle interior. It is now possible to prevent Above weather strip 1
The glass abutting surface 14a of No. 4 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). In addition, 15
1 is a door trim attached to the inner panel 6 of the door body 5, and 16 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 inner portion 9c and outer portion 9d of the roller portion 9a of the upper roller 9 are supported by the guide member 8 by the spring force of the spring 13.
are separated from each other within the range of play 12 between them and are tilted inward into the vehicle body.

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 contacts the weather strip 14 on the vehicle body side (the upper edge of the door opening 2) (see FIG. 4b).

In this case, the weather strip 14 has its glass contact surface 14a facing outward and downward and is inclined, and the upper end of the door glass 4 contacts the contact surface 14a horizontally from the outside. Of the weather strip 14, especially the corner portion 14b sandwiched between the glass contact surface 14a and the inner surface is elastically deformed,
Due to the elastic deformation of the corner portion 14b, 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. This reaction force R causes the door glass 4 to move against the spring force of the spring 13 within the range of the play 12 between the guide member 8 and the upper roller 9 (the inner part 9c of the roller part 9a of the upper roller 9 and the outer part (within the range where the portions 9d overlap with each other) swings outward from the vehicle body around the lower roller 10, and due to the combination of this outward swing and the closing operation of the side door 3,
The upper end of the door glass 4 bites substantially upward into the glass contact surface 14a of the weather strip 14 (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 14 at the upper end of the door glass 4 which is tilted inward from the vehicle body. It comes into pressure contact with the weather strip 14 at a position higher than the dimension D and bites deeply into the weather strip 14 (see FIG. 4d). In addition, here, the above-mentioned dimension D is the guide member 8 and the upper roller 9.
is determined by the size of the play 12 between.

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 14 gradually decreases, so that the door glass 4 is affected by the spring force of the spring 13. Therefore, when the upper end of the door glass 4 is separated from the weather strip 14 by gradually tilting inward from the vehicle body with the lower roller 10 as the center, the door glass 4 has a play 12 between the guide member 8 and the upper roller 9. The split car body tilts inward and returns to its original state, and the weather strip 14 also returns to its original state without elastic deformation, so that the side door 3 can be opened smoothly.

In addition, when the door glass 4 is raised and lowered in the closed state of the side door 3, when the handle of the raising and lowering drive mechanism is operated, the upper roller 9 is moved to a state in which the inner portion 9c and the outer portion 9d of the roller portion 9a are overlapped with each other. The guide member 8 together with the lower roller 10
As a result, the door glass 4 moves up and down while being supported by the rollers 9 and 10 and the guide member 8.

In this case, a spring 13 is provided between the inner portion 9c and the outer portion 9d of the upper roller 9.
does not come into direct contact with the guide member 8, and the channel depth at the upper end of the guide member 8 is deeper than at other parts, but since it is formed continuously so as not to create a step, the guide member 8 The sliding resistance (frictional resistance) in the mechanism can be reduced, and the door glass 4 can be smoothly raised and lowered. In addition, both the inner and outer parts 9c, 9 of the upper roller 9
d also comes into contact with the guide member 8 on the side due to the biasing force of the spring 13, but since the contact friction between the two members 9 and 8 is very small, this does not hinder the raising and lowering of the door glass 4. It will never come.

Further, when the door glass 4 is raised to the highest position, a weather strip 14 (glass contact surface 14) is attached to the upper end of the door glass 4 near the highest position.
a), an external force is applied to the outside of the vehicle body, so that the inner portion 9 of the roller portion 9a of the upper roller 9
c and the outer portion 9d are not separated from each other by the spring force of the spring 13 and maintain an overlapping state, and in the highest position, the upper end of the door glass 4 is directed outward from the vehicle body in the same way as when the door is closed. In the swung state, it bites deeply into the weather strip 14 on the vehicle body side and is pressed into contact with 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 R that acts on the weather strip 14 is different from the direction of the external force R that acts 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 14a.

Therefore, in this way, not only can the opening/closing operation of the side door 3 and the raising/lowering operation of the door glass 4 be performed smoothly without any influence, but also the side door 3 can be closed at the highest position of the door glass 4. In both cases, and when the door glass 4 is raised to the highest position with the side door 3 closed, the upper end of the door glass 4 is deeply dug into the weather strip 14 on the vehicle body side, and the weather strip is removed. Since it can be supported by the vehicle body 1 via the lip 14, the lower part of the door glass 4 is supported by the guide member 8 and the rollers 9, 10, and the door glass 4 at the highest position The support of the government can be strengthened.
As a result, the occurrence of the suction phenomenon of the door glass 4 during high-speed driving can be reliably prevented, and vibration noise can be reduced.

Moreover, the digging of the door glass 4 into the weather strip 14 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.

Moreover, compared to the conventional structure, the support structure for the door glass 4 is such that the guide member 8 is simply placed between the guide member 8 and the upper roller 9 at the highest position of the door glass 4.
The upper roller 9 is divided into two parts 9c and 9d, an inner and outer part. Since this is a simple structure that merely includes a spring means (spring 13) that applies a spring force in a direction in which the door glass 4 is tilted inward to the vehicle body in a state where it is expanded in the width direction of the vehicle body, it can be implemented at low cost. This is advantageous in terms of implementation. In addition, in the case of this support structure, the assembly of the upper roller 9 is simply done by simply attaching both the inner and outer parts 9 of the upper roller 9 attached to the door glass 4.
c and 9d are overlapped against the biasing force of the spring 13, and the upper roller 9 is moved to the lower roller 10.
Similarly, it is sufficient to simply insert the guide member 8 into the guide member 8 through the open opening at its upper end, which can be done easily and quickly.

Furthermore, since the weather strip 14 itself on the vehicle body side does not require any changes in its shape, material, etc., the sealing function of the weather strip 14 can be maintained well and a good appearance can be ensured.

In the above embodiment, the roller portion 9a of the upper roller 9 is divided into an inner portion 9c and an outer portion 9d.
A spring 13 between the two parts 9c and 9d applies a spring force in a direction that always tilts the door glass 4 inward in the vehicle body with both parts 9c and 9d expanded in the width direction of the vehicle body at the highest position of the door glass 4. However, in the present invention, it is of course possible to use other spring means such as elastic rubber instead of the spring 13.
