The window molding

is attached to the window plate

, and after discharging an adhesive agent
8
into the gap to dam rubber
7
, it is inserted between the space-forming surface
2
b
of the body panel
2
in the x-arrow direction and the adhesive agent is hardened to produce a window.
However, such a structure of the window molding
4
allows the linking lip
4
f
to be deformed greatly and easily in the up-and-down direction, and the friction caused by the space-forming surface
2
b
makes it not only difficult to insert into the space
5
, but presents a problem that, in the assembled state, the sealing lip
4
e
is allowed to float during highspeed cruising, due to a negative pressure created at the external surface of the window molding, resulting in generating abnormal sound (whistling sound).
The window molding
4
shown in
FIG. 5B
has omitted the sealing lip
4
e,
and the linking lip
4
f
is exposed externally so that, by pressing the linking lip
4
f
towards the x-direction to insert into the space
5
, it is attached to the window plate
3
and is fixed in place by the adhesive agent
8
.
However, such a window molding
4
presents a problem that, due to size variations in the body panel
2
and window plate
3
and the like, when the space
5
is wide, a gap is created between the linking lip
4
f
and the space-forming surface
2
b,
or when the space
5
is narrow, the linking lip
4
f
protrudes outwardly to spoil the appearance. Also, because a bent section
9
is formed on the linking lip
4
f,
when a negative pressure is generated at the external surface during highspeed cruising, the upper section of the linking lip
4
f
can easily be floated, and after the floating, it is difficult to be reverted.
SUMMARY OF THE INVENTION
The subject of the present invention is to provide a window molding that can be installed easily to result in an installation that remains stable and has a superior external appearance, that does not cause lifting and noise generation even during highspeed cruising, and in which the sealing lip is made thin to facilitate the surfaces to be flush.
The problem has been solved according to a window molding of the present invention as follows.
(1) A window molding comprises:
a molding body attached along a space between a window plate and a body panel;
a protruding rib protruding from the molding body towards an external surface of the window plate;
a leg section extending from the molding body towards the space;
a sealing lip extending from the molding body towards an external surface of a body panel;
a linking lip extending from the leg section towards the space-forming surface of the body panel and linking with a tip of the sealing lip or in a vicinity of the sealing lip to form a hollow section.
(2) A window molding according to the features presented in (1), wherein the leg section has an engaging section to engage with the window plate.
(3) A window molding according to one of features (1) or (2), wherein the linking lip is linked at an acute angle of incline towards the tip direction of the sealing lip.
(4) A window molding according to one of features (1) to (3), wherein the linking lip is formed with a convex surface section on the leg section side, and a concave surface section on the sealing lip side.
(5) A window molding according to one of features (1) to (4), wherein the molding body has a water receiving section in the side section.
The window molding according to the present invention is suitable for installing on the windshield plate, but it can also be applied to the rear window and other vehicular windows. Specially it is suitable for use in the upper section of the window plate which encounters severe air stream during cruising so that it may be installed only in the upper section of the window plate. It may also be installed so that the molding is formed integrally with an upper segment extending along the upper section of the window plate, a side segment pair extending along the side section of the window plate, and a corner segment pair continuously connecting the upper segments with the side segments. In the latter case, a water receiving section (weir) may be formed in the side segments of the window molding.
The molding body is constructed with an elongate member so that it can be attached along the space between the window plate and the body panel. Extending from the molding body, the protruding rib extends towards the external surface of the window plate, the leg section extends towards the space, the sealing lip extends towards the external surface of the body panel, and the linking lip links the leg section and the tip section of the sealing lip or its vicinity, resulting in the window molding that can be made as a unit with the molding body. These components may be integrated by using a process such as extrusion molding of synthetic resin (including rubber), and in this case, it is permissible to make a composite using a synthetic resin and a profiled metal strip as a core member, and may be formed as a composite of several materials such as rigid synthetic resin and plasticized (soft) synthetic resin formed into a single unit.
It is preferable that the protruding rib in the upper section be made so that the tip is close to the external surface of the peripheral section of the window plate, because flush surfacing can be facilitated, but in the side segments, rain water from the window plate can be stopped by forming a water receiving section.
It is preferable that the leg section be provided with an engaging section to engage with the window plate because firm fixation to the window plate can be achieved, and the window molding can be fixed in the correct orientation, but if other means are used for fixation, the engaging section can be omitted.
It is preferable that the sealing lip be extended to reach to external surface of the body panel, because it hides the space and produce superior appearance. It is preferable that the sealing lip be made gradually thinner towards the tip end, from the viewpoints of strength, external appearance and flush surfacing.
It is preferable that the linking lip be protruding from the leg section towards the space-forming surface of the body panel to extend along the space-forming surface from the abutting section, thereby linking with the tip section of the sealing lip or in its vicinity to form a hollow section, because the pressing force towards the space-forming surface can be i
