Abstract

PURPOSE:To improve sealability and durability by inserting a spacer into a notch formed in the base of a subseal part, deforming an edge of the notch along the spacer, while making this edge contact with the top of a main seal part and thereby constituting a relay part there. CONSTITUTION:A notch 12 is formed in a part (forming a relay part 10) of the base of a subseal part 7. Next, a spacer 13 consisting of sponge rubber is inserted into this notch 12. This spacer 13 is made into such a form as extending in a hollow part of the subseal part 7 from a water supplying groove 8. When the spacer 13 such like is inserted thereinto, an edge at the upper side of the notch 12 is deformed along a surface form of the spacer 13, and it comes to an almost flat surface part 11 and contacts with the top of a main seal part 6. Consequently, the whole surface part inclusive of the relay part 10 comes to a smooth skin layer by means of extruding molding. In consequence, sealability and durability both are improved as compared with the conventional one.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to a weatherstrip for a sashless door type vehicle.

2. Description of the Related Art An example of a weather strip for a sashless door type vehicle as shown in FIG. 5 is shown in FIG. 6.

This weather strip 1 has a hollow support 4 extending from a mounting base 3 held by a retainer 2 on the vehicle body side, and a peripheral edge of a door glass 5 touches the outer side of the support 4. A hollow main seal part 6 that is in contact with the main seal part 6 and a hollow sub-seal part 7 that is in contact with the end surface of the door glass 5 are extended, and one water supplementary groove 8 is connected to the main seal part 6 and the sub-seal part 7. It has a built-in structure. When the door glass 5 rises, the main seal part 6 and sub-seal part 7 seal the peripheral edge and end face of the door glass 5 at the same time, and the water adhering to the end face of the door glass 5 is discharged from the water trapping groove 8 to the outside of the vehicle. do.

By the way, in the case of a satsuru door type car without a center pillar, a center seal rubber 9 as shown in FIG. 7 is attached to the rear door glass 5, and this center seal rubber 9 is attached to the rear door glass 5. As it rises, its upper end comes into contact with the weather strip 1. 6th
In the weatherstrip 1 shown in the figure, if the transition portion 10, which is in contact with other members such as the center seal rubber 9, is also formed into the above-mentioned cross-sectional shape, the contact surface against the other member (for example, the (Part indicated by A)
This results in problems such as poor sealing performance.

Therefore, conventionally, as shown in FIG.
Only O is molded so that the tops of the main seal part 6 and the sub-seal part 7 are connected in a substantially flat plane, and the ends of other members (for example, center seal rubber 9) are connected to this transition part 1.
A weather strip 1 has been developed which is adapted to abut on a substantially planar portion 11 of the weather strip 1. The molded portion is indicated by B in the figure.

Problems to be Solved by the Invention However, in the conventional weather strip structure described above, the transition portion 10 of other components is formed by molding, so the sealing surface is smaller than that of other extruded spherical portions. The problem is that it is inferior in terms of durability and durability.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a weather strip for a sash-less door type vehicle that has excellent sealing performance and durability by forming all parts of the surface that come into contact with other members by extrusion molding.

Means for Solving the Problems As a means for solving the above-mentioned problems, the present invention provides a main seal part, which the peripheral edge of the door glass comes into contact with, on the side surface of the support column extended to the mounting base, and a main seal part of the door glass. This is a basic cross section provided with a hollow sub-seal part whose end surfaces abut, and a water supplementary groove connected to the main seal part and the sub-seal part. In a weather strip in which a transition portion is formed in which the top portions are connected in a substantially flat surface, a notch is formed in a part of the base of the sub-seal portion, and the water-supplementing groove is inserted into the hollow portion of the sub-seal portion. The transition portion is constructed by inserting an extending spacer, deforming the edge of the notch along the spacer, and connecting the edge to the top of the main seal portion.

Function: By taking such measures, when the door glass is raised with the door closed, or conversely, when the door glass is raised and the door is closed, other parts attached to the door glass will be damaged by the spacer. The side and end surfaces come into contact with the section. Furthermore, during manufacturing, the surface of the transfer section can be made into a skin layer by extrusion molding.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. Incidentally, the same parts as those shown in the drawings from FIG. 5 onward are denoted by the same reference numerals, and explanations of some overlapping parts will be omitted.

1 and 2, the weather strip 101 according to the present invention is similar to the conventional weather strip whose basic cross section is shown in FIG.
It has the same shape as strip 1. That is, a hollow support section 4 is extended to the mounting base 3, and a hollow main seal section 6 and a hollow sub-seal section 7 are extended to the side surfaces of the support section 4. It has a shape in which water supplementary grooves 8 are connected. And other parts (
For example, the structure of the transition portion 10 that the center seal rubber 9) comes into contact with is significantly different from that of the conventional weather strip 1.

When forming the transition part IO, first, the entire length of the weather strip 101 in the longitudinal direction is formed into the above-mentioned basic cross section by extrusion molding, and then, as shown in FIG. A notch 12 is formed in the portion forming the transfer portion 10). In the case of this embodiment, the notch 12 has notches 1 at both ends of the linear notch 12a.
2b. Next, a spacer 13 made of sponge rubber is inserted into this notch 12. This spacer 13 is shaped so that when inserted into the notch 12, it extends from the water supplementary groove 8 into the hollow part of the sub-seal part 7. When the spacer 13 is inserted in this way, the upper edge of the notch 12 is deformed along the surface shape of the spacer 13, and becomes a substantially planar portion 11 as shown in FIGS. connected to the top of the

The weather strip 101 is constructed in this manner, but since the entire length in the longitudinal direction is once shaped by extrusion molding, the entire surface portion including the transition portion 1O becomes a smooth skin layer formed by extrusion molding.

When the door glass 5 is raised with the door (not shown) closed, or conversely when the door is closed with the door glass 5 raised, other members attached to the door glass 5 (for example, the center seal rubber 9) comes into contact with the transfer section 10. At this time, the other member (center seal rubber 9)
As shown in the figure, a flat portion 11 and a spacer 13 inside it
．． The main seal portion 6 is also deformed, and in this state it comes into close contact with the flat portion 11. Here, since the plane portion 11 of the transfer portion 10 is a skin layer, it is in close contact with another member (center seal rubber 9) smoothly and with high sealing performance.

In addition, in the above explanation, weather strip, whelk 10
Although the contact portion of the center seal rubber 9 has been cited as an example of the adoption of method 1, this is not limited to the contact portion of the center seal rubber 9, but it is also possible to adopt the contact portion of a corner piece, the end portion of a door, etc. Effects of the Invention As described above, according to the present invention, the transition part is formed in the same way as the conventional one by molding, such as the external shape, etc.
It is possible to obtain a sufficient contact surface with other parts, and in addition, the surface of the transition part can be made into a skin layer by extrusion molding, so by doing this, the transition part can be smoothly and reliably attached to other parts. You will be able to make close contact. As a result, both sealing performance and durability are improved compared to conventional ones.
