Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a weather strip in which a stopper part that restricts movement of the door is formed in a molded part while elastically contacting the other door or body when the door of the automobile is opened and closed.
[0002]
[Prior art]
A description will be given with reference to FIG. 2. Description of the Related Art Conventionally, for example, in an automobile having a pillarless kannon door that does not have a center pillar, has a front door 2 coupled to a body 1 at its front end with a hinge 4 and a rear door 3 coupled to a body 1 at its rear end with a hinge 4. There is a type in which a stopper portion 32 is protruded from a mold forming portion 31 that forms upper and lower ends of a front end portion of a weather strip 30 attached to the rear door 3.
[0003]
When the front door 2 is closed with the rear door 3 closed, the stopper portion 32 elastically contacts the rear end of the front door 2 to regulate the rotation of the front door 2 and smoothly close the door. Has a function to manifest sex.
[0004]
[Problems to be solved by the invention]
In the weather strip having such a configuration, there is a weather strip in which a central portion of the tip of the stopper portion 32 is depressed and a cylindrical wall is provided. Since this stopper part 32 has the cylindrical wall surrounding, it is rich in cushioning properties and has the advantage that the rotation of the front door 2 can be more smoothly regulated.
[0005]
However, the stopper portion 32 is easily adsorbed to the front door 2, so that there is a problem that an abnormal noise (so-called an abnormal noise) is generated when the door is closed or opened.
[0006]
The present invention was devised in view of these problems, and a weather strip having a stopper portion that can prevent a situation in which an abnormal noise is generated by being attracted to the other door or body when the door is opened and closed is provided. The issue is to provide.
[0007]
[Means for Solving the Problems]
This will be described with reference to FIGS. The weather strip 10 with a stopper portion according to the first invention does not have a center pillar, the front door 2 is coupled to the body 1 at the front end portion thereof by the hinge 4, and the rear door 3 is hinged to the body 1 at the rear end portion thereof. In the pillarless guanyin door of the automobile connected at 4, a stopper portion 12 that is attached to the rear door 3 and elastically contacts the front door 2 to restrict its rotation when the front door 2 is closed is formed in the mold forming portion 11. It is a weather strip, and is provided with a recessed portion 13 at the center of the tip of the stopper portion 12 so as to surround a cylindrical wall 14, and at least one notch groove 15 is provided in the cylindrical wall 14.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show an embodiment of a weather strip 10 with a stopper according to the present invention. 1 is a body panel, 2 is a front door panel, 3 is a rear door panel, 4 is a hinge provided at the front end of the front door or the rear end of the rear door 3, 5 is an opening seal provided at the periphery of the body opening, and 16 and 17 are rear doors. When the front door is closed when the rear door is in the closed state, the rear edge 2a of the front door comes into contact with the outer seal portion and the inner seal that are provided at the front end of the front and rear to be sealed. The upper and lower end portions of the outer seal portion 16 and the inner seal portion 17 are molded products 11 and have a flange portion 17a extending forward. The flange portion 17a is sandwiched between the opening seal 5 and the front door 2. It is like that. The weather strip 10 does not have a center pillar, and the front door 2 is coupled to the body 1 at the front end thereof by the hinge 4 and the rear door 3 is coupled to the body 1 at the rear end thereof by the hinge 4. In the pillarless kannon door, it is attached to the rear door 3.
[0009]
The weather strip 10 is a stopper portion that restricts the rotation of the front door 2 when the front door 2 is closed with the rear door 3 closed and the front end of the rear door 3 is elastically contacted with the rear end of the front door 2. 12 protrudes from the mold forming portions 11 at the upper and lower ends of the rear door 3.
[0010]
Further, the weather strip 10 has, at its front end, an inner seal portion 17 that elastically contacts the step portion 2a on the vehicle interior side 40 of the front door 2 and the opening seal 5 attached to the body 1, and the vehicle exterior side of the front door 2. The outer seal portion 16 that elastically contacts the 50 step portions 2 b is provided, and the stopper portion 12 is provided adjacent to the outer seal portion 16. A seal member (weather strip) 20 is also attached to the front door 2.
[0011]
In the weather strip 10 having such a configuration, a cylindrical wall 14 is provided so as to project along the peripheral end portion by forming a depressed portion 13 by forming a depressed central portion of the stopper portion 12. Then, two notch grooves 15 are formed in the cylindrical wall 14. In addition, the stopper part 12 is made into the substantially short cylinder shape which set the diameter of the base part to be a little larger than the diameter of a front-end | tip part.
[0012]
The operation of the weather strip 10 with the stopper will be described. When the front door 2 is closed with the rear door 3 closed, the front end portion of the weather strip 10 attached to the rear door 3 abuts against the rear end portion of the front door 2. At this time, the stopper portion 12 of the weather strip 10 is elastically contacted with the front door 2, but a notch groove 15 is formed in the cylindrical wall 14 of the stopper portion 12, so that the occurrence of abnormal noise that has occurred conventionally has occurred. Can be prevented in advance.
[0013]
That is, by forming the notch groove 15, when the front door 2 is closed, the air in the recessed portion 13 can pass through the notch groove 15 and escape to the outside. Therefore, since the inside of the depressed portion 13 is not decompressed, the stopper portion 12 is prevented from adsorbing to the front door 2, and as a result, occurrence of an abnormal noise caused by the adsorption can be prevented. In addition, since the notch groove 15 is formed, the contact area between the cylindrical wall 14 and the front door 2 can be reduced, and this can also suppress the occurrence of abnormal noise.
[0014]
In the present embodiment, the stopper portion 12 is attached to the rear door 3 of the pillarless door and is elastically contacted to the front door 2. However, the present invention is not limited to such a form, and is attached to the front door 2. In addition, it can be attached to a general rotary door or a sliding door, and can be elastically contacted with the body 1. It can also be attached to the body 1.
[0015]
【The invention's effect】
According to the first aspect of the present invention, in the weather strip 10 which is attached to the rear door 3 of the pillarless door and is formed with the stopper portion 12 in the molded portion 11, at least one notch is formed in the cylindrical wall 14 of the stopper portion 12. Since the groove 15 is provided, the inside of the depressed portion 13 is not decompressed when the door is closed or opened. Therefore, it is possible to prevent occurrence of abnormal noise when the door is opened and closed.
