Description

[Detailed Description of the Invention] The present invention relates to a sealing structure for separable joints in a vehicle body.

Conventionally, for example, the body of a Land Cruiser type vehicle,
As shown in FIG. 1, the frame member of the roof panel 3 is separated from the upper joint surface of each frame member of the windshield 1, the side panel 2, and the rear panel (not shown), and the side panel 2 and rear panel are configured respectively. separating and disassembling each upper frame member from each lower frame member;
Furthermore, the frame member of the windshield 1 is configured to be tilted forward and fixed. However, when the vehicle body disassembled as described above is assembled at a manufacturing factory to form a vehicle compartment during use, each of the frame members described above must be joined to each other at their end surfaces, and such It is necessary to seal the vehicle interior of this configuration to prevent rainwater from entering the vehicle interior from around each joint end surface. by the way,
Conventionally, as shown in FIGS. 5 and 6, as a sealing structure for such joint end surfaces, a buffer member 33 having a sealing function, such as cushion rubber, is interposed between the joint end surfaces of two separable frame members 31 and 32. , a main gasket 34 is attached to a portion of the outer end surface side of the buffer member 33 on the outer surface formed by joining the frame members 31 and 32, and There is a structure in which the outer surfaces of the frame members 31, 32, and 35 are sealed from each other by closely contacting a weather strip 36 fixed to the outer surface opposite to the outer surface. As a result, in such a sealed structure, both the first and second frame members 3
1 and 32 are sealed by a buffer member 33, and both frame members 31 and 3
The difference in level between the two members 31 and 32 caused by an assembly error on the outer surface of the second frame member 35 is corrected by the packing 34, and the space between the outer surface of the two members 31 and 32 and the outer surface of the third frame member 35 is weathered. It is sealed by a lip 36. However, in such a sealed structure, a gap R is created between the inner surface of the packing 34 and the outer end surface of the buffer member 33, and rainwater infiltrates through this gap R as shown by arrow B in FIG. A sealer is applied to the outer end surface of the buffer member 33 in advance to a predetermined thickness, and the sealer is covered by the packing 34. Therefore, in such a sealed structure, the sealer shrinks due to heating during the heating and drying process of the car body at the factory, and as a result, pinholes are generated on the inner surface of the gasket 34, and rainwater enters through the pinholes. Sometimes. Further, in the vehicle body of the above type, when the user separates the components of the vehicle interior, the gasket 34 is removed and the sealer falls off from the outer end surface of the buffer member 33. Therefore, when the user reassembles the vehicle compartment, the two frame members 31,
32, simply attach the sealer 34 to the buffer member 33 without adhering the sealer.
Since it is merely attached, rain leakage will occur at each joint that makes up the passenger compartment.

In order to solve the above-mentioned problems, the present invention has been developed by attaching a highly elastic soft packing such as a rubber foam to the inner surface of the packing (hereinafter referred to as the main packing) in advance in an unremovable manner, and attaching the soft packing to the cushioning material. The present invention aims to provide a sealing structure that is brought into close contact with the outer end surface of a member in a liquid-tight manner, and examples thereof will be described below with reference to the drawings.

In the drawings, FIG. 2 shows a state in which the present invention is implemented at the joint between the frame member 21 of the windshield 1 and the frame member 22 of the front panel shown in FIG. In this structure, as clearly shown in FIG. 3, a buffer member 23 such as cushion rubber is adhered to the upper end surface of the frame member 22 of the front panel over the entire length of the joint end surface. The lower end surface of the windshield frame member 21 is pressed onto the upper surface. In this way, both frame members 2 joined to each other
A main packing 24 is bonded between the outer surfaces of 1 and 22 and to the end surfaces on the indoor side with adhesive. By the way, in the present invention, this main packing 24
A highly elastic soft packing 25 made of rubber foam or the like is preliminarily adhered to the inner surface of the buffer member 23 in a non-releasable manner (see Fig. 4), and this soft packing 25 is attached to the outer end surface of the buffer member 23 as shown in Fig. 3. They are in a liquid-tight state. Further, a weather strip 26 is fixed around the front portion of the front door screwed onto a pillar portion constituted by the frame member 22 of the front panel, and this weather strip 26 covers the front door. When closed, it comes into close contact along the outer surfaces of both frame members 21 and 22 on the vehicle body side, and also comes into close contact with the outer surface of the main gasket 24, serving to prevent rainwater from entering from the outside.

In such a sealed structure, the gap between the inner surface of the main packing 24 and the outer end surface of the buffer member 23 is completely closed by the compressed soft packing 25.
It is possible to reliably prevent rainwater from entering this joint, which has been a problem in the past. In order to ensure perfect contact between the main packing 24 and the weather strip 26, it is desirable that the upper and lower ends of the main packing 24 be made as flat as possible.

In summary, in the present invention, as exemplified in the above embodiment, a soft packing is preliminarily adhered to the inner surface of the main packing attached to the outer surfaces of two frame members to be joined to each other, and the soft packing is The gist of this is that the packing fluid-tightly contacts the outer end surface of the buffer member interposed between the joint end surfaces of the two frame members, and this eliminates the problem of the conventional problem with the outer end surface of the buffer member. In addition, even when the user disassembles and reassembles the components of the vehicle interior, it is possible to reliably prevent rainwater from entering due to the application of the sealer in the main packing. Because it is always attached to the specified location when applying,
Rain leakage in the passenger compartment after reassembly can be completely prevented. In addition, in implementing this invention,
Although an example in which the present invention is applied to a joint between a windshield frame member and a front panel frame member has been described, the present invention can also be applied to substantially the same joints in other parts of the vehicle interior. The applicability is clear.
