Description

[Detailed Description of the Invention] The present invention relates to a weather strip suitable for synthetic resin doors of vehicles.

A vehicle door is provided with a glass plate that moves up and down to open and close the window, and a gap is provided between the base of the window frame and the upper edge of the inside of the door and between the outer panels, that is, the lower edge of the window, for the sliding of the glass plate. A weather strip is installed in this gap to prevent water from entering the inside of the door.

Conventionally, vehicle doors are formed from steel plates, and the upper sides of the inner and outer panels are provided with opposing bending parts that have an inverted U-shape in cross section.A weather strip is attached to this part, and the folding Since high rigidity is provided at the top edge of the door, the weather strip has a core metal vertically embedded in the main body of rubber etc., and has rigidity only in the vertical direction where the glass plate goes up and down. Prevents lifting etc. Therefore, the weather strip prevents the glass plate from rising and falling in the vertical direction, and prevents the weather strip from coming off. does not contribute much.

By the way, in order to reduce weight, it is planned to mold the inside and outside panels of the door from synthetic resin, but in this case, molding bends and ribs on the opposing upper edges of the inside and outside panels would be troublesome in terms of molding. Furthermore, if ribs or the like are formed, there is a risk that sink marks may occur and the appearance of the outer surface may deteriorate. Since the reinforcement function is based on the assumption that the door is made of steel plate, it is difficult to say that it is sufficient.

This invention was made to improve the above-mentioned disadvantages of weather strips mainly used for synthetic resin doors. An outwardly protruding engaging portion is molded integrally with the main body using rubber or the like, and a core metal that is continuous vertically within the main body and horizontally within the engaging portion is buried in a substantially horizontal T-shape. A vehicle door weather strip suitable for use with synthetic resin doors is designed to increase the rigidity and attachment in the sliding direction of the glass plate and the lateral direction of the inner and outer panels in the vertical and horizontal parts. It is on offer.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of the door 1. The door 1 is composed of an assembled body of an outer panel 2 and an inner panel 3. A sash 22 is provided on the assembled body, and a space between the inner and outer panels (not shown) is provided. A device for lifting and lowering the glass plate 23 is installed inside. The above inner and outer panels are molded from synthetic resin.

FIG. 2 is _an enlarged sectional view taken along the line 2-2 in FIG _. The glass plate 23, which is housed in the space S between the inner and outer panels, moves up and down to open and close the window. Protrusions 4 and 5 are protruded from the upper ends of the inner and outer panels so as to face each other. The above-mentioned gap _S1 will be formed between 5a. The protrusions 4 and 5 each have an inner surface 4a,
Lateral engaging grooves 4b and 5b are formed from 5a outward in the case of the outer plate 2 and inward of the vehicle interior in the case of the inner plate 3, and the upper surfaces 4c and 5c of the protrusions 4 and 5 It is tilted slightly in the direction.

The weather strips are attached to the outer plate side and the inner plate side in pairs, and have a substantially symmetrical shape. The weather strip 6 is provided with tongue pieces 8 and 9 integrally provided at the upper and lower ends of the inner surface 7a of the vertically elongated main body 7, and a covering piece 10 is integrally provided at the upper end of the outer surface of the main body 7 to project outward. do. A locking protrusion 1 of a predetermined length is integrally protruded outward from the middle part in the height direction of the outer surface 7b of the main body 7, and a plurality of attachment protrusions 1 are integrally provided above and below the protrusion 11 and spaced apart in the length direction. Friction pieces 12 are provided protrudingly, and each of the above parts is integrally molded from rubber or the like. A core metal 13 is embedded in the main body 7 and the protruding piece 11. The core metal 13 has a vertical portion 13a that vertically connects the width direction, that is, the middle part in the thickness direction, of the main body 7, and a vertical part 13a that connects the middle part in the width direction, that is, the thickness direction, of the main body 7, and a part from the middle part of the vertical part 13a to the height direction of the projecting piece 11, that is, the middle part in the thickness direction. In the embodiment, it is formed by forming a steel plate into a horizontal T-shape, and the horizontal part 13b is a stacked structure with an outer end bent.

The weather strip 6 is inserted into the gap S1 so as to face the inner surface of the protrusion of the outer panel 2, and the protrusion piece ₁₁ is inserted into the groove 4.
This insertion into b is performed while bending the friction pieces 12, resulting in press-fitting or light pressure, and the cover piece 10 overlaps the portion of the upper surface 4c of the protrusion 4 in the gap direction. In this way, the weather strip 6 is attached to the upper edge of the outer panel 2.

The weather strip 14 of the inner plate 3 has a substantially symmetrical shape, with the tongue piece 1 facing the main body 15 and the tongue pieces 8 and 9.
6, 17, a protruding piece 19 having friction pieces 20 that engage with the grooves 5b, and a covering piece 18.
It is entirely molded with rubber etc. so that it is embedded.

The weather strips 6, 14 are assembled on the left and right sides of the gap _S1 , with the tongue pieces 8, 16 and 9, 17 facing each other,
The glass plate 23 moves up and down between these positions, and the tongue piece slides into and seals the inside and outside of the glass plate. By the way, the weather strips 6, 14 have vertical parts 13a, 21a,
Since the horizontal portions 13b and 21b are provided integrally with this,
This gives rigidity to the upper openings of the inner and outer panels of the door, that is, the gaps, in the vertical direction and in the inner and outer directions, that is, in the vehicle width direction. Rigidity can be provided by the weather strip itself without forming curved parts or ribs. Since the protrusions 11 and 19 having friction pieces are engaged with the horizontal grooves, the weather strip is firmly connected to the door.

FIG. 3 shows a modified embodiment of the weather strip, in which the protrusion 11 of the weather strip 106 is
No friction piece is provided on the weather strip 1, the thickness of this piece is made thicker than the height of the groove 4b, and the protruding piece 111 is force-fitted into the weather strip 114.The other weather strip 114 is also symmetrical in shape; In this embodiment, the amount of protrusion of the lower tongue piece 106 of the weather strip 106 is made small.

As is clear from the above, according to the present invention, the stiffness in the vertical and horizontal directions can be increased by the weather strip attached to the inner and outer panels of the synthetic resin door without providing ribs or bent parts on the upper edges of the inner and outer panels. In addition, the weather strip has an outwardly protruding locking portion that firmly locks onto the upper edge of the inner and outer panels, which is a major feature that contributes to the realization of a synthetic resin door.
