DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stepped opening formed between a peripheral portion of a window plate of an automobile and a window frame of a body to close the stepped opening to enhance the appearance of this portion. And a method for molding the same.

[0002]

2. Description of the Related Art As one of the above-mentioned moldings for a window plate (hereinafter simply referred to as "molding"), the molding is attached to an upper edge of a window plate fixed to a window frame opening of a body panel and side edges thereof. The upper edge molding part and the side edge molding part are integrally formed in a series, and in the cross-sectional shape,
It is known that the overall height of the side edge molding is higher than that of the upper edge molding, and a rainwater guide groove is provided toward the inner peripheral side of the window frame opening (Japanese Utility Model Application Laid-Open No. 63-4712).
JP-A-1-244820), a window plate is inserted between the head and the upper support projection at the upper edge, and between the upper support projection and the lower support projection at the side edge. .

[0003] However, when the window plate is fixed to the window opening of the body panel and then the molding is fitted into the gap between the two, the support projection (lip) extending to the rear surface of the window plate is usually relatively small. It is often provided small and the engagement is often unstable. Of the two publications, the former does not describe the state of the corners, and the latter does not, but the upper and lower support pieces are cut off, so the engagement is extremely low. It is unstable.

[0004]

SUMMARY OF THE INVENTION A first object of the present invention is to stabilize the molding with respect to the window plate even when the supporting projection (lip) extending to the back side of the window plate is short. That is, it can be mounted in the engaged state. A second object of the present invention is to improve the attachment of a molding at a corner portion of a window plate.

[0005]

In order to solve the above-mentioned problem, the present invention provides a molding device having the above-mentioned structure, in which the depth of the stepped opening between the periphery of the wind plate and the window frame of the body panel is reduced. When the height of the decorative portion in the indoor / outdoor direction changes in response to the change in height, the holding lip provided on the leg and the panel lip provided on the side opposite to the holding lip of the leg are provided. Along the indoor and outdoor directions
That is, the relative positional relationship has not been changed.

[0006] Since the entire molding is pressed against the window plate by the reaction force of the panel lip elastically contacting the body panel, the panel lip elastically contacts the panel lip even if the pinching lip extending to the back side of the window plate is short. By the reaction force, the peripheral edge of the window plate can be stably held between the holding lip and the decorative portion, and the state of attachment of the molding to the window plate is stabilized.

Also, since the relative positional relationship between the sandwiching lip provided on the molding leg and the panel lip in the indoor and outdoor directions is unchanged, the elastic contact reaction force of the panel lip acts on the molding. The position at which the molding is pressed against the window plate is constant with the depth of the step-shaped opening formed between the periphery of the window plate and the window frame of the body panel. Regardless, it is constant over the entire circumference of the molding. For this reason, the attachment state of the molding is substantially constant over the entire periphery of the window plate, and the attachment of the molding to the window plate is enhanced. Here, if the positions of the panel lip and the holding lip provided on the leg are substantially the same with respect to the decorative portion, the elastic contact reaction force of the panel lip directly acts on the holding lip, The molding can be most effectively attached to the wind plate.

[0008]

The step-shaped opening 4 formed as a step between the peripheral portion of the window plate G and the body panel 3 of the window frame differs depending on the position where the width and depth are provided. That is, as shown in FIG. 2 to FIG. 4, the width of the step-like opening 4 provided at the corner of the window plate G becomes narrower as approaching the upper peripheral edge of the window plate G, and the depth thereof also increases. It becomes shallower as it approaches the upper edge of the wind plate G.

[0010] As shown in FIGS. 2 and 3, the clamping lip 5 on the inner side of the lower end of the leg portion 1 of the side edge molding part Ma, also each panel lip 6 collision on its outer circumference A groove lip 7 is provided on the inner peripheral side of the decorative portion 2.
But also on the outer peripheral side decorative lip 8 are projected respectively. The side edge molding portion Ma is sandwiched by the side peripheral edge of the wind plate G by the portion on the inner peripheral side of the leg portion 1 in the decorative portion 2 and the holding lip 5 provided on the leg portion 1. The panel lip 6 is in elastic contact with the inclined portion 3 a of the body panel 3, and the tip of the decorative lip 8 constituting the decorative portion 2 is in elastic contact with the upper surface of the body panel 3. A groove lip 7 is provided on the inner peripheral side of the decorative portion 2, and a space between the groove lip 7 and the surface of the window plate G is a rainwater guide groove 9. In addition, the above-mentioned “inner side” means “inside the window frame opening”.
"Center side" and "outer side" means "the opposite side"
Side ".

As shown in FIGS. 2 and 4, in the upper edge molding portion Mb, the thickness Tb of the decorative portion 2 is smaller than that of the side edge molding portion Ma, and the groove lip 7 is formed in the wind plate. G is elastically contacted with the upper surface, and the rainwater guiding groove 9 is not formed. The holding lip 5 and the panel lip 6 are also provided on the upper edge molding portion Mb in exactly the same manner as the side edge molding portion Ma, and the upper edge molding portion Mb is formed by the holding lip 5 and the decoration portion 2. , Are sandwiched by the periphery of the wind plate G. Here, the depth of the step-shaped opening 4 at the upper edge of the wind plate G is smaller than the depth at the side edge thereof, and accordingly, the upper edge molding portion Mb
Of the leg 1 is shorter than that of the side edge molding Ma. Moreover, as shown in FIGS. 2 to 4, the moldings Ma, Ma at the side edges and the upper edge.
In Mb, even if the height of the decorative part 2 is different,
There is no change in the relative position between the holding lip 5 and the panel lip 6 provided at the lower end of the leg 1 along the indoor and outdoor directions . That is, the holding lip 5 and the panel lip 6
It is provided on each of the inner peripheral side and the outer peripheral side of the leg 1.

The width of the stepped opening 4 formed in a stepped manner between the peripheral edge of the window plate G and the body panel 3 of the window frame is narrow at the upper peripheral edge of the window plate G. It is wider at its side edges and, correspondingly, as shown in FIGS. 3 and 4,
The elastic contact length of the body panel 3 to the inclined portion 3a of the panel lip 6 having the same length is longer at the upper peripheral edge of the wind plate G and shorter at the side peripheral edge thereof.
Furthermore, in any part of the side edge molding part Ma and the upper edge molding part Mb, the distance between the sandwiching lip 5 and the lower surface of the decoration part 2 corresponds to the thickness of the wind plate G, and the molding M is: It is held by the wind plate G over its entire length. When the molding M is attached to the peripheral edge of the window plate G in this manner, the panel lip 6 elastically contacts the inclined portion 3a of the body panel 3, and the side edge and the upper edge are formed by the elastic contact reaction force. The leg portions 1 of the molding portions Ma and Mb of the edge are pressed against the end face of the window plate G, thereby securely attaching the molding M to the window plate G. Moreover, the holding lip 5 and the panel lip 6 provided at the lower end of the leg 1 are provided at substantially the same position along the width direction of the leg 1 (vertical direction in FIGS. 3 and 4). The elastic force of the holding lip 5 acts so that the holding lip 5 is securely held at the corner of the window plate G. As described above, the mounting force of the molding M on the window plate G is determined by the clamping force (engaging force) at which the three portions of the leg 1, the decorative portion 2, and the clamping lip 5 clamp the peripheral edge of the window plate G.
This is based on a synergistic effect of the panel lip 6 and the elastic contact reaction force of the panel lip 6. For this reason, even if the holding lip 5 is shortened in order to enable retrofitting of the molding M (mounting of the molding M in a gap between the body plate 3 and the window plate G after the window plate G is fixed to the body panel 3), even if the window plate The necessary mounting force of the molding M to G can be secured.

Further, as shown in FIG. 2, at the corner Mc of the molding M, the thickness of the decorative portion 2 of the side edge molding Ma is increased in accordance with the shape of the stepped opening 4. At the same time, the width of the decorative portion 2 is gradually reduced as approaching the edge molding portion Mb.
It gradually narrows as it approaches the upper edge molding portion Mb. The part of the decorative part 2 where the width changes is
This is the portion of the decorative lip 8 on the outer peripheral side. For this reason, even if the width and depth of the step-shaped opening 4 formed between the peripheral portion of the window plate G and the window frame of the body at the corner of the window plate G change, Molding M attached to the relevant part of G
Since the width and thickness of the corner portion Mc of the molding M vary according to the width and depth of the stepped opening portion 4 provided at the corner portion of the window plate G, respectively,
The surface of the decorative part 2 which constitutes is maintained over the entire length. The crossing angle of the decorative part 2 with respect to the leg part 1 is constant in all parts. Furthermore, rainwater guide groove 9 is gradually its aperture width (length in a direction perpendicular to the glass surface of the window plate G) W ₀ is narrowed, it disappeared in the portion connecting the upper molding part Mb .

The molding M of this embodiment may be inserted into a window frame while being attached to the window plate G, or the window plate G may be inserted into the window frame in advance.
Thereafter, the molding M may be inserted. In any case, since the panel lip 6 is configured to elastically contact the inclined portion 3a of the body panel 3, the molding M can be stably inserted into the window frame. A core 11 for reinforcement is embedded in the leg 1 of the molding M, and a decorative tape 12 is adhered to the upper surface of the decorative part 2. In addition, in FIG. 2 to FIG.
