Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a door glass run fitted along a door frame of an automobile.

[Prior Art] In a door 1 having a door frame 2 as shown in FIG. 1, a door glass run G is fitted to the door frame 2 as shown in FIG.

The door glass run G is made of rubber or synthetic resin, and is attached to the door frame 2 having a U-shaped cross section when the main body 4 is attached.
Has a U-shaped cross section, and the holding lips 6 engaging with the frame 2 project outward from the outer surfaces of both corners 40 of the main body 4, and the sealing lips 5 extend from both ends of the main body 4 on the opening side. There is. Then, the door glass 3 is sandwiched by both seal lips 5 from both sides.

[Problems to be Solved by the Present Invention] By the way, the door glass run G is fitted into the door frame 2, but should be held at the center of the door frame 2 in such a shape that both corners should be right angles. However, the shape may be inclined and biased to one side. That is, the corner portion 40 is thin so as to bend at a predetermined position, and if the holding lip 6 is thickened, the workability of pushing the door glass run G having the narrowed opening side into the door frame 2 is deteriorated. However, the shape retention of the corner portion 40 and the supporting force of the retaining lip 6 are low. Therefore, the above-mentioned deviation occurs due to variations in the pushing direction into the door frame 2.

When this deviation occurs, the sealing force of the seal lip 5 becomes lower than in the case of the normal position, the door glass run G is easily removed, and when the door glass 3 enters the glass run G and is closed. The protrusion 51 of the seal lip 5 may be caught.

Therefore, an object of the present invention is to provide a door glass run which has good workability in assembling to a door frame having a narrow opening side and which does not cause the above-mentioned deviation in the assembled state.

[Means for Solving the Problems] The present invention, as illustrated in FIG. 2, includes a main body 4 having a U-shaped cross section, seal lips 5 extending from both ends of the main body 4 on the opening side, and a main body 4 of the main body 4. A door glass run G fitted with a door frame 2 having a U-shaped cross section with a narrow opening side, which is provided with holding lips 6 whose both thin ends of the bottom wall 41 are connected to the left and right side walls 42 and which project from the outer surfaces of both corners 40. At the bottom wall
41 or the side wall 42 (bottom wall 41 in the figure) is obliquely projected so as to cross the inside of the corner part 40, and the tip abuts the other wall (side wall 42 in the example) so that the corner part 40 It is characterized in that a lip-shaped rib 7 that determines the angle of is formed.

[Effects] When the door glass run G is fitted into the door frame 2, the ribs 7 on both sides abut on the opposing walls to determine the angle of the corner portion 40, so that the door glass run G is offset or inclined. Absent. Therefore, the desired sealing property is secured. Further, when one corner portion 40 is bent into an acute angle to fit the door glass run G into the door frame 2 whose opening side is narrowed, the side wall
The tip end of the rib 7 that comes into contact with the slanting direction 42 slidably slides on the side wall 42 surface without being caught, so that it can be bent and the workability of assembling is not hindered.

[Embodiment] In the embodiment shown in FIG. 2, the door glass run G is an integrally extruded rubber body, and the seal lips 5 are directed inward from both ends on the opening side of the main body 4 having a U-shaped cross section. The holding lip 6 projects from the outer surfaces of the both corner portions 40 of the bottom wall 41, both ends of which are connected to the side wall 42. The inner surface of the corner portion 40 is lightened to facilitate bending.

Further, inside the corner portion 40, ribs 7 project from the left and right sides of the bottom wall 41 diagonally toward the side wall 42 so as to cross the inside of the corner portion 40. The length of this lip-shaped rib 7 is such that when the corner portion 40 is substantially right angle, the tip end is a side wall 42.
It is the length to abut. On the other hand, the door frame 2 into which the door glass run G is fitted has a U-shaped cross section, and the opening side is narrowed.

Then, this door glass run G has one corner 40
The door frame 2
However, at this time, the tip of the rib 7 that comes into contact with the side wall 42 in an oblique direction slides on the surface of the side wall 42 without being caught, so that the bending of the corner portion 40 is not obstructed by the rib 7. After the pushing, the one corner portion 40 having an acute angle is pushed open by the reaction force of the ribs 7, and finally both ribs 7 are balanced so as to come into contact with the both side walls 42 with the same pressure contact force. The portion 40 has a right-angled shape. Therefore, even if it is pushed in from an oblique direction, it is not fitted into the door frame 2 in a state of being inclined and biased as in the conventional case.

Since both holding lips 6 are evenly engaged with the door frame 2, the holding lips 6 are less likely to come off than when they are offset, and both seal lips 5 are in contact with the door glass 3 with the same pressing force, so that the sealing property is also high. Good.

Although the rib 7 is made to project from the bottom wall 41 in the above-mentioned embodiment, the same action and effect can be obtained even if the rib 7 is made to project from the side wall 42 and its tip abuts on the bottom wall 41 as shown in FIG.

In addition, in the above-mentioned embodiment, both seal lips are shown extending obliquely inward and inward of the main body portion, but one seal lip extends obliquely inward and inward similarly to the above, and the other seal lip is main body. It may extend obliquely toward the door glass in the outward direction of the part, or both seal lips may extend obliquely outward.
