SPECIFICATION
GLASS RUN SEAL STRUCTURE BACKGROUND OF THE INVENTION 1. Field of the Invention: The present invention relates to a glass run seal structure for sealing a joint between a drip moulding and a door frame, and a joint between the door frame and a door glass plate.
2. Prior Art: A conventional glass run seal structure will be now described with reference to Figs. 1 to 4. Conventionally, as a glass run seal structure for sealing a joint between a drip moulding 10 and a door frame 20 as well as a joint between the door frame 20 and a door glass plate 50, there is 15 employed a glass run seal structure comprising an inside seal 30 for elastically contacting the inner surface of the door glass plate 50 and an upper seal 40 for elastically contacting the upper end surface of the door glass plate 50, the inside seal 30 being separated from the upper seal wherein the inside seal 30 is composed of a base 31 which engages with a lower side sash 21 of the door frame 20 and a hollow seal portion -32 for elastically contacting the inner surface of the door glass plate 50, the base S 31 being integrally connected to the hollow seal portion 32, and the upper seal 40 is composed of a base 41 which engages with an upper side sash 22 of the door frame 20 and a door glass plate receiving portion 42 having a U-shaped cross section for receiving the upper end portion of the door glass plate 50, the base 41 being integrally connected to the door glass plate receiving portion 42, and wherein an inner lip 43 for elastically contacting the upper end surface of the door glass plate 50 protrudes from the inner surface of the door glass plate receiving portion 42, and an upper lip 44 for elastically contacting the drip moulding 10 protrudes from the upper surface of the door glass plate receiving portion 42.
However, the conventional glass run seal structure has a problem that since there remains considerably large gap portion S formed by the inner side surface of the door glass plate 50, the upper side surface of the hollow seal portion 32 of the inside seal 30 and the indoor side surface of the door glass plate receiving portion 42 of the upper seal 40 when the door glass plate 50 is closed as shown in Fig. 3, the inside seal 30 retracts so that the hollow seal portion 32 and the door glass plate 50 are sealed by line contact. Accordingly, the conventional glass run seal structure is inferior in sealing performance. Further, there is another problem that a hang portion of the indoor side of the door glass plate receiving portion 42 is tapered in the lower direction so that the hollow seal portion 32 is pulled 15 down by the door glass plate 50 to be turned down when the door glass plate 50 moves downward as shown in Fig. 4.
Problems to be solved by the invention are as follows.
In the conventional glass run seal structure, when the door glass plate 50 is closed the inside seal 30 retracts so that the hollow seal portion 32 and the door glass plate 50 are sealed by line contact.
Accordingly, the conventional glass run seal structure is inferior in sealing performance between the hollow seal portion 32 and the door glass plate 50. Further, the hollow seal portion 32 is pulled down by the door glass plate 50 when the door glass plate 50 moves downward so that the hollow seal portion 32 is turned down.
SUMMARY OF THE INVENTION P:\WPDOCS\AMD\SPECI\585614.NIS 2913/99 -3- Accordingly, it is an object of the present invention to overcome the aforementioned drawbacks of the conventional glass run seal structure and to provide a glass run seal structure which is excellent in sealing performance and is not turned down.
In accordance with the invention, there is provided a glass run seal structure comprising: an inside seal which is attached to a lower side sash of a door frame for elastically contacting an inner side surface of a door glass plate; and an upper seal which is attached to an upper end surface of said door glass plate, said inside seal being separated from said upper seal; wherein a projection portion is formed in an upper end of a hollow seal portion of said inside seal which hollow seal portion elastically contacts said door glass plate for contacting a stop portion of said upper seal to be retained thereby, said stop portion being formed in a hang portion of an indoor side of a door glass plate receiving portion, which substantially has a U-shaped cross section for receiving an upper end portion of said door glass plate, so as to prevent said hollow seal portion from being pulled down by said door glass plate when said •door glass plate moves downward.
Preferably, an indoor side surface of said projection portion is inclined upward and inward and an outdoor side surface of said stop portion is inclined downward and outward so that 20 said projection portion can be retained by said stop portion.
Preferably, said projection portion is formed in a hook shape directed towards and inward and said stop portion is formed in a hook shape directed upwards and outward so that said projection can be hooked by said stop portion.
