Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a door weather strip channel structure for an automobile, and more particularly to a seal structure for a channel joint.

[Prior Art] A weather strip 3 for sealing between a door frame 1 and a door opening of a vehicle body 2 is mounted around a door frame 1 of an automobile as shown in FIG. FIG. 2 shows a typical example of a conventional panel door.
Is joined along the outer periphery of the door frame 1 by joining the door frame 1 and the channel 4 and fitting the base portion of the weather strip 3 into the bent flange of the channel 4.

By the way, in the above-mentioned panel door, a sealer 5 is applied to one of the joint portion of the outer panel 11 and the inner panel 12 of the door frame 1 and one of the flange bending tip portions of the channel 4 in order to prevent intrusion of rainwater from the outside of the vehicle. It is necessary, however, that the bent surface of the flange 4 of the channel 4 has a small bending surface, and the applied sealer 5 is the weather strip 3.
There is a risk that it will flow into the side and hinder the attachment of the weather strip 3, and that a sealer coating failure will occur at the flange bending tip of the channel 4 and that rust will occur at the flange end due to the entry of rainwater and the like. To prevent such rusting, it is sufficient to reapply a sealer and perform a sealer finishing work with a spatula.However, such a measure requires a considerable amount of man-hours and a large amount of sealer for re-applying the sealer and spatula finishing work. It didn't work as a viable solution because of the need.

[Problems to be Solved by the Invention] In view of the above-mentioned problems, the present invention is a complete sealer that prevents the sealer from flowing down, does not require recoating of the sealer and finishing with a spatula, and does not cause rust at the joint portion of the channel. An object of the present invention is to provide a weatherstrip channel structure capable of performing a sealer coating process.

[Means for Solving Problems] In the weather strip channel structure of the present invention, one end of the bent flange of the weather strip channel joined to the door frame is formed into a substantially L-shape, and the weather strip channel is upwardly connected to the door frame. Forming an open sealer pool, and filling the sealer pool with the sealer to cover the flange bending tip.

[Embodiment] FIG. 1 shows a channel structure of the present invention. The channel is joined to the outer peripheral surface of the inner panel 12 of the door frame 1 at the bottom surface thereof, and the bending flanges 41, 41.
Then, the base portion of the weather strip 3 is fitted. On one side of the bent flange 41 of the channel 4, a dam flange 6 is extendedly formed in a substantially L shape to form a sealer pool 7 which is open to the upper side together with the inner panel 12. 5 is a sheila,
It is filled in the seeder pool 7 and covers the flange tip 61 of the dam flange 6.

When the sealer 5 is filled with the sealer 5, the tip of the sealer gun is used as a guide for the rising of the dam flange 6 to fill the sealer 5 with the sealer 5 so that the sealer 5 is exposed to the outside. It solidifies in the sealer pool 7 without spilling.

[Effect of the Invention] The weather strip channel structure of the present invention has a sealer pool whose upper end is opened with the door frame by forming one end of the bending flange of the weather strip channel joined to the door frame into a substantially L shape. Since the flange bending tip is covered by filling the sealer pool with the sealer, the tip of the sealer gun is formed into an L-shaped bent flange in the sealer applying step at the joint between the door frame and the channel. If you fill the sealer in the sealer pool using the rising as a guide,
Without flowing into the weather strip side by the dam flange, and at the same time, cover the tip of the bending flange,
It can be completely waterproofed. Furthermore, it is not necessary to re-apply the sealer and finish with a spatula, and since the dam flange serves as a guide when applying the sealer, the application amount is constant,
It is possible to reduce the amount of sealer applied and the work of applying sealer.

Claims (1)

[Scope of utility model registration request] Claim: What is claimed is: 1. One end of a bent flange of a weather strip channel joined to a door frame is formed into a substantially L-shape to form a sealer pool having an open upper side with the door frame, and the sealer pool is filled with the sealer. The weather strip channel structure is characterized in that the flange bending tip is covered thereby.
