Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door window guide structure, and more particularly to an improvement of a mounting portion for fixing a movable window guide member to a window plate.

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 of the movable window and guides the guide roller so as to maintain a predetermined locus by vertically slidingly supporting the guide roller by a channel type guide rail fixed to the door frame. There is something to equip.

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 in a flat shape with a certain degree, it is possible to avoid winding at the position of the mounting member, but there is a possibility that the lip portion of the door outer weather strip will still be caught on this flat surface and will be wound inside. Inevitable.

In view of the above, an object of the present invention is to provide a vehicle door window guide structure improved so as to surely prevent the lip portion of the door outer weather strip from being caught in the mounting portion of the guide member.

In the guide structure for a vehicle door window according to the present invention, the lip portion and the outer surface of the door outer weather strip are made to correspond to the mounting portion for fixing the guide member of the movable window to the window plate. A substantially flat strip-shaped mounting member that slides is adhered to the outer surface of the window plate along the upper side of the lower end of the movable window that is below the lower lip of the door outer weather strip at the top dead center position of the movable window. The boss-like portion that projects from the mounting member and fixes the guide member is integrally formed so as to be located in the opening of the window plate. In addition to this, the outer surface of the mounting member can be configured so as to form and coat a slipping film layer, and the tip end side of the lip portion should be formed so as to be recessed in accordance with the outer surface shape of the mounting member. You can

In this vehicle door window guide structure, the attachment member is attached to the outer surface of the window plate along the upper side of the lower end of the movable window at the top dead center position beyond the lip portion of the door outer weather strip. Since it is molded, there is no possibility that the tip end of the lip portion is constantly wound over and abutted on the mounting member and the tip end of the lip portion is wound inward. Also, since the boss-like portion for mounting the guide member of the movable window is integrally formed on this mounting member by projecting so as to be positioned inside the opening of the window plate, the guide member can be mounted without providing a separate mounting member. become able to. If the outer surface of the mounting member is coated with a lubricous coating layer, the tip side of the lip portion can be brought into sliding contact with the surface of the mounting member very smoothly. By correspondingly forming the depressions, the sliding contact with the mounting member can be made more smoothly.

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

This vehicle door window guide structure is an example of an ascending / descending window in which the window moves vertically as shown in FIG. 1, and is applied to a mechanism for guiding the ascending / descending movement of the movable window 1 so as to maintain a predetermined trajectory. The guide member 2 is equipped with a guide roller 20 mounted on the inner surface side of the window plate 10 and a channel-shaped guide rail 21 usually fixed to the door frame. The guide roller 20 is a roller support 20a made of light metal such as die-cast or high-strength plastic.
Is applied to the inner surface of the window plate 10 and the bolt shaft portion 20b protruding from the support 20a is inserted into the opening 11 provided in the plate surface of the window plate 10 to form a boss-like portion described later. It is fixed with screws. Further, a door outer weather strip 4 is attached to the panel side 3 of the door where the movable window 1 moves up and down along the upper edge where the outer panel 3a and the inner panel 3b are in contact with each other. On the weather strip 4, a seal lip 4a made of synthetic rubber or soft synthetic resin rich in rubber elasticity or flexibility is integrally formed with the molding body 4b, and the tip end of the seal lip 4a is projected so as to come into sliding contact with the window plate 10. It is arranged. On the outer surface side of the window plate 10 with which the seal lip 4a is slidably contacted, a mounting member 5 having a substantially flat outer surface and having a strip plate shape is provided at a mounting portion for fixing the guide member 2 of the movable window 1 to the window plate 10. Correspondingly, and at the top dead center position of the movable window 1, the lip portion of the door outer weather strip 4
It is adhered and molded along the upper side of the lower end 51 located below the 4a. The mounting member 5 is integrally formed with a boss-like portion 5a so as to project so as to be located in the opening 11 of the window plate 10. The boss portion 5a is supported by screwing the bolt shaft portion 20b of the guide roller 20 into the support base 20a.
The guide plate 20 is mounted by sandwiching the window plate 1 between the mounting member 5 and the mounting member 5, and a buffer or spacer member 5c may be interposed between the mounting member 5 and the support base 20a. The mounting member 5 integrally formed with the boss-like portion 5a may be formed by die-casting light metal or molded by high-strength plastic similarly to the roller supporting base 20a. It is preferable to form the lubricous coating layer 5c of a resin material having a high lubricity such as ethylene resin. In this case, if a material having a small coefficient of friction with respect to the seal lip 4a is used, the formation of the slip resin can be replaced.

In the vehicle door window guide structure configured as described above, the tip side of the seal lip 4a slides on the outer surface side of the window plate 10 as the movable window 1 moves up and down by the guide of the guide member 2. Since the lower end 51 of the movable window 1 is located at the top dead center position of the movable window 1 and below the tip of the seal lip 4a, the mounting member 5 is constantly straddled so that it does not come into contact with the protruding portion during the downward movement. It does not receive the force to deform it downward. Therefore, the tip end side of the seal lip 4a can be reliably prevented from being wound downward. Further, when the movable window 1 moves upward, the mounting member 5 works to push up the seal lip 4a, so that the situation where the seal lip 4a is caught and deformed inside does not occur. When the lubricous coating layer 5c is formed and coated on the surface, the sliding contact can be made extremely smoothly. In addition to that, as shown in FIG. 2, a concave recess 4c is formed on the tip side of the seal lip 4a so as to correspond to the outer surface shape of the mounting member 5, so that it slides more smoothly along the mounting member 5. You can move. The recess 4c can be shaped by heating and softening the seal lip 4a to locally and permanently deform it.

Further, as shown in FIG. 3, 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 5 so that the guide member 2 and the like are not visible.

As described above, according to the guide structure for a vehicle door window according to the present invention, the mounting member on which the lip portion of the door outer weather strip always straddles the boss-like portion for fixing the guide member to the outer surface of the window plate. Since the lip is integrally formed with the lip, the lip can be reliably prevented from being caught when the movable window moves downward, and a slipping film layer is formed on the outer surface of the mounting member or the tip of the lip portion is formed. It is possible to make the lip portion slide extremely smoothly by forming the side in a recess corresponding to the shape of the outer surface of the mounting member.
