Description

TECHNICAL FIELD The present invention relates to a vehicle door window guide structure, and more specifically, a mounting member for fixing a guide member of a movable window to a window plate slides on a lip portion of a door outer weather strip. It relates to the improvement of the outer surface side in contact.

2. Description of the Related Art Generally, in a movable window for a vehicle, a guide shaft is screwed to a button-like mounting member that affixes a bolt shaft portion to be inserted into an opening of a window plate from an inner surface side to an outer surface side of the window plate to fix a guide roller to the window plate. A guide member that is mounted on the inner surface side of the vehicle and guides the guide roller so that the up and down movement of the movable window maintains a predetermined locus by slidably fitting and supporting the guide roller with a channel type guide rail fixed to the door frame. Some are equipped with.

Conventionally, in this guide structure, the tip end side of the lip part integrally formed with the door outer weather strip is easily caught by the outer peripheral edge of the mounting member and is wound inward as the movable window moves up and down. A spacer having a substantially trapezoidal side surface with a slope portion that reduces the height from the center to the vertical end is provided on the outer surface side of the window plate near the mounting location of the member, and the mounting member is the door outer weather strip. It is known that the lip portion is pushed up before it comes into contact with the lip portion to form an air gap between the window plate and the lip portion (Shokaisho 62.
-44719).

However, in this guide structure, since the spacer is mounted separately from the mounting member, it is unavoidable that the number of parts and the assembling process are increased, and the center portion of the spacer has a certain rising height. Since it is formed flat with a certain degree, it is possible to avoid winding at the position of the mounting member, but on this flat surface the lip portion of the door outer weather strip may still be caught and caught inside. I cannot avoid it.

In this regard, the present invention focuses on the outer surface shape of the mounting member,
An object of the present invention is to provide a vehicle door window guide structure improved so as to prevent the lip portion of the door outer weather strip from being caught by the mounting member.

In a vehicle door window guide structure according to the present invention, an attachment member for fixing the guide member of the movable window to the window plate is provided on the outer surface that is in sliding contact with the lip portion of the door outer weather strip. The slope part that projects from the ground contact surface of the plate with a gentle upslope and the step part that suddenly changes to the down slope from the slope part to the ground contact surface are connected, and the step part moves and descends. It is configured by being provided in the front of the direction. Additionally, the outer surface of the mounting member can be configured to be coated with a lubricious coating layer.

In this vehicle door window guide structure, as the movable window moves, the mounting member comes into contact with the lip portion formed from the elastic material of the door outer weather strip from the lower end side, and at the slope portion thereof. Even if the tip end side of the lip part is elastically deformed downward, if the movable window moves as it is, the tip end side of the lip part is pushed by the step part that changes abruptly from the slope part of the mounting member toward the ground contact surface. Since the lip part restores to its original shape due to the elastic deviation when there is no part to attach,
It is possible to prevent a situation where the tip end side of the lip portion is rolled inward. By forming and covering the outer surface with a lubricious coating layer, it is possible to prevent the tip side of the lip part from being rolled up, and even if it is rolled up, it can elastically deviate very smoothly and restore its original shape. You can Also,
Even when the guide member is screwed and fixed to the guide member, the mounting member can be held and fixed so as not to rotate at the step portion, so that the guide member can be reliably mounted at a predetermined position.

Embodiments The following will be described with reference to the accompanying drawings.

This vehicle door window guide structure is applied to a mechanism for guiding the vertical movement of the movable window 1 on the side of the vertical window where the window moves in the vertical direction as shown in FIG. The guide member 2 is equipped with a guide roller 20 mounted on the inner surface of the window plate 10 and a channel-shaped guide rail 21 normally fixed to the door frame. The guide roller 20 is disposed on the inner surface of the window plate 10 via a roller support base 20a made of light metal such as die-cast or high-strength plastic, and the bolt shaft portion 20b protruding from the support base 20a is used as a window. By being inserted into the opening 11 provided in the plate surface of the plate 10, it is screwed and fixed to the button-shaped mounting member 3 which is placed on the outer surface side of the window plate 10 via the spacer 22. A door outer weather strip 5 is attached to the panel side 4 of the door where the movable window 1 moves up and down along the upper edge where the outer panel 4a and the inner panel 4b are in contact with each other. A seal lip 5b formed integrally with 5a and made of synthetic rubber having high rubber elasticity or flexibility or soft synthetic resin is arranged so as to project so that its tip end side is in sliding contact with the window plate 10. The seal lip 5b is also in sliding contact with the outer surface of the mounting member 3 on an extension line of the window plate 10, and the outer surface of the mounting member 3 projects from the ground surface of the window plate 10 with a gentle upward slope. The inclined surface portion 3a and the stepped portion 3b that suddenly changes in a downward slope from the inclined surface portion 3a toward the ground contact surface are continuously provided. The slope 3a and the step 3b are provided so that the slope 3a is located on the lower side and the step 3b is located on the upper side in a state of being used by being attached to the window plate 10, and these are also shown in FIG. As described above, the inclined surface portion 3a and the stepped portion 3b may be provided as a set and continuously provided in a plurality of stages. Also, the third
It is sufficient to provide one set as shown in the figure, and it is possible to use a die-cast light metal or a high-strength plastic molded as in the roller support 20a. As shown in FIG. 1, it is preferable to form the lubricous coating layer 3c on the outer surface of the mounting member 3 with a resin material having a high lubricity such as tetrafluoroethylene resin. Further, as shown in FIG. 4, an opaque colored layer 12 may be provided on the inner surface side of the window plate 10 corresponding to the mounting position of the guide member 2 including the mounting member 3 so that the guide member 2 and the like are not visible.

In the vehicle door window guide structure constructed as described above, the seal lip side is shown to move in order to avoid complication of the drawing in FIG. 1, but the outer surface of the window plate 10 moves as the movable window 1 moves downward. When the seal lip 5b, which comes into sliding contact with the side, comes into contact with the mounting member 3, when its tip end is caught by the lower end edge of the mounting member 3, it makes slidable contact with the inclined surface portion 3a and is gradually elastically deformed downward. This elastic deformation is maintained while it is in sliding contact with the sloped portion 3a, but when it reaches the stepped portion 3b located on the upper side, the portion that presses the tip side disappears immediately and elastically restores to the original shape. Come to do. Even if the tip side of the seal lip 5b is wound downward due to this elastic deviation, it is possible to reliably prevent the state from being maintained, and further, the slipping film layer 3c is formed on the outer surface of the mounting member 3. The seal lip 5b
It becomes difficult for the tip end side to be rolled up, and even if it is rolled up, it is possible to extremely smoothly elastically deviate and restore the original shape. Also, as shown in FIGS. 1 and 2, the slope 3a
If a plurality of steps and the stepped portion 3b are provided, the seal lip 5b
Since the amount of deformation can be suppressed to a relatively small amount, elastic restoration can be performed quickly, which is preferable.

Since the stepped portion 3b is provided on the outer surface of the mounting member 3 when the guide member 2 is mounted, the mounting member 3 can be rotated by the stepped portion 3b as the bolt shaft portion 20b is screwed. Is also preferable. Further, in the above-described embodiment, the case where the window moves up and down has been described, but this can be similarly applied to the case where the window moves in the horizontal direction.

As described above, according to the vehicle door window guide structure according to the present invention, the lip portion of the door outer weather strip is provided by providing the stepped portion continuous from the slope portion on the outer surface of the attachment member. Therefore, it is possible to reliably prevent the guide member from being wound inward, and it is possible to reliably fix the guide member because the mounting member can be prevented from rotating when the guide member is fixed by screwing.
