Description

[Technical Field] The present invention relates to a vehicle door sash structure, and more particularly to a door sash structure for mounting a door sash molding in an opening for a door glass integrally provided in a door panel.

"Prior Art and Problems Thereof" A door molding of a vehicle has an upper edge portion having a substantially U-shaped cross section. Further, a part of the door panel is extended upward to form an opening for a door glass (door sash, hereinafter referred to as a panel opening),
Door sash moldings are installed along the panel opening. This door sash molding is desirable to have a flush surface (flush) with the door glass and the panel opening as much as possible in order to reduce the appearance and wind noise, and therefore various conventional sash structures have been proposed. Has been done. However, the conventional structure generally forms a U-shaped portion on the inner peripheral edge of the door sash molding,
Since this U-shaped portion embraces the inner peripheral edge of the panel opening, the thickness in the cross-sectional direction inevitably increases,
The distance from the door glass was large. That is, it was difficult to make a flash surface. Moreover, the mounting structure for the door sash molding on the door panel opening was complicated, and the mounting workability was poor.

[Objective of the Invention] The present invention solves the above problems of the conventional door sash structure, and can further increase the flush surface of the door panel opening, the door sash molding attached to the door panel, and the door glass. The purpose is to obtain a door sash structure with excellent mounting workability.

[Summary of the Invention] For this reason, the present invention has a door sash structure for a vehicle in which a panel opening surrounding the periphery of the door glass is formed integrally with the door panel, and the door sash molding is installed along the inside of the panel opening. In the outer surface of the panel opening of the door panel, a plurality of cut-and-raised protrusions which are spaced apart and are directed outward are formed, and a locking edge having a substantially semicircular cross section is formed at the inner peripheral edge of the panel opening. , On the other hand, in the door sash mall,
An enclosing engagement portion having a U-shaped cross section that engages with a cut-and-raised protrusion of the panel opening is formed on the outer portion thereof, and an engagement edge of the semicircular cross-section on the inner peripheral edge of the panel opening portion is formed on the inner portion thereof. It is characterized in that an engaging portion that elastically engages is formed.

"Embodiment of the Invention" The present invention will be described below with reference to illustrated embodiments. FIG. 3 shows a door panel to which the door sash structure of the present invention is applied. The door panel 11 extends upward in the front and rear of the upper portion thereof to form a panel opening 13 surrounding the door glass door glass 12. The door sash molding 30 is mounted along the inside of the panel opening 13, and the door molding 14 is mounted along the upper edge of the door panel 11. The door molding 14 generally has an inverted U-shaped cross section, but the present invention does not matter about the structure of the door molding 14.

The panel opening 13 (door panel 11) includes an outer panel 15 and an inner panel 16. The outer panel 15 has a contact portion 1 with the vehicle body 29 on the outer side thereof.
7 and the inner part is welded to the inner panel 16. The inner panel 16 has a substantially U shape so as to form a run channel for advancing and retracting the door glass 12, and the door glass 12 advances and retracts in the U-shaped portion. Inner panel 1
A weather strip 18 is attached to the inside of 6 to prevent rainwater from coming into contact with the door glass 12.

A cut-and-raised protrusion 20 which is a feature of the present invention is formed in the panel opening 13, and an engaging edge 21 having a semicircular cross section is formed on the inner peripheral edge thereof. Cut and raised protrusion 20
As is apparent from FIGS. 1 and 2, the outer panel 1
5 are formed at appropriate intervals in the engaging portion 22 formed on the inner side of the outer surface of the member 5, and face outward. The inner end of the outer panel 15 is folded back outward in a U-shape, and the folding edge 23 forms a locking edge 21 having a substantially semicircular cross section at the inner peripheral edge of the panel opening 13. .

On the side of the panel opening 13 (door panel 11) having the above configuration, the door sash molding 30 has a core metal 31 of uniform cross section.
And a decorative elastic body 32 that covers the outside of the core metal 31, and is located in the engaging portion 22 of the outer panel 15,
It is substantially flush with the outer panel 15. And the core metal 31 is
A U-shaped embracing engaging portion 33 that is cut and raised and is engaged with the protrusion 20 is provided on the outer side portion, and an engaging portion 34 that elastically engages with the engaging edge 21 is provided on the inner side portion. . Included locking part 33
Holds the outer end portion of the cut-and-raised protrusion 20, and the holding lock prevents the door sash molding 30 from coming off.

The door sash molding 30 is capable of rotating (swinging) and moving around the vicinity of the engagement portion 33 and the cut-and-raised protrusion 20 in the engaged state. The engaging portion 34 is locked to the locking edge 21 of the panel opening 13. That is, the engaging portion 34 has a shallow U-shaped portion 35 that elastically engages with the locking edge 21, and a U-shaped portion 36 that is continuous from the U-shaped portion 35 to the door glass 12 side and is in the opposite direction. And has an S-shaped cross section.

Therefore, according to the sash structure having the above-described configuration, the holding locking portion 33 of the door sash molding 30 is locked to the cut-and-raised protrusion 20 of the panel opening 13 (door panel 11), and in this state, the inside of the door sash molding 30 is locked. It can be mounted by pushing the part inwards. That is, when the inner portion of the door sash molding 30 is pushed inward, the inverted U-shaped portion 36 of the engaging portion 34 first comes into contact with the locking edge 21 of the panel opening 13. When a further pressing force is applied inward in that state, the inverted U-shaped portion 36 elastically deforms and escapes from the locking edge 21, and eventually the U-shaped portion 35 elastically engages with the locking edge 21. . It is desirable to preset the curvatures of the U-shaped portion 35 and the locking edge 21 to be as equal as possible. In this engaged state, the inverted U-shaped portion 36 exerts a resistance force against the removal and does not come out unless an external force is applied. In other words, the amount of protrusion of the inverted U-shaped portion 36 toward the locking edge 21 side is determined so that the mounting resistance and the removal resistance are exhibited in a well-balanced manner.

According to the above sash structure, the door sash molding 30
In particular, since the inner peripheral edge is not in the shape of enclosing the inner peripheral edge of the panel opening 13, the distance 1 from the surface of the door glass 12 to the surface of the door sash molding 30 can be made smaller than that of the conventional structure. That is, a door sash structure with a high flush surface can be obtained.

The decorative elastic body 32 is integrally formed on the outer surface of the cored bar 31 by injection molding. The shape is determined so as to be as flush with the outer panel 15 as possible.

Further, the door sash molding 30 can be divided into a plurality according to the shape of the panel opening 13.

[Advantage of Invention] As described above, according to the present invention, since there is no U-shaped portion inside the door sash molding, a door sash structure with a high flush surface degree of the door sash molding and the door glass can be obtained. . Also, the door sash molding should be attached to the panel opening of the door panel only by pushing the inner part of the door sash inward with the hugging engagement part engaged with the cut-and-raised protrusion of the panel opening. As a result, a door sash structure with good workability can be obtained.
