JPS5821768Y2 - Joint structure between automobile window frame and center channel - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a joint structure between an automobile window frame and a center channel.

When dividing a car window frame into, for example, a square window and a triangular window using a center channel, the metal window frame and center channel come into direct contact at the junction between the horizontal window frame and the vertical center channel. This tends to cause rust, and if a gap is left, water leakage may occur, so a sealing material is provided at the joint.

In this case, conventionally, in the invention described in Japanese Utility Model Publication No. 53-5694, as shown in FIG.
A sealing material 3 made of rubber or plastic was installed between the outer upper edge of the window frame 1 and the center channel 2, but since the sealing material 3 is a small part that is only inserted at the joint between the window frame 1 and the center channel 2, it is difficult to manage the parts. It is difficult to assemble, and it may fall off or be forgotten during assembly, resulting in poor workability and lack of reliability.Furthermore, there is no sealing material between the inner upper end of the center channel 2 and the window frame. However, there are drawbacks such as the fact that it is difficult for dirt and other objects to enter the vehicle, and rainwater from outside can enter the interior of the vehicle.

Further, depending on the type of vehicle, the shapes of the parts on the left and right sides of the vehicle may differ, making it more difficult to manage the above-mentioned parts and also deteriorating the ease of assembly.

This idea was made in view of the above-mentioned drawbacks, and it is a weather sealing material that covers the edge of the window frame and/or center channel with a sealing material that is interposed both on the outside and inside of the joint between the window frame and the center channel. - It is characterized by being molded integrally with the strip, and aims to improve assembly workability, reduce the number of man-hours for molding parts, and simplify management.

This invention will be explained in detail below with reference to embodiments shown in the drawings.

Fig. 2 shows the upper part of the rear door of an automobile, 4 is a window frame of the rear door, 5 is a vertical center channel that joins the horizontal part of the window frame 4, and the center channel 5 connects the window frame 4 to the rear door glass. It is divided into two parts: a rectangular window into which the 6 is fitted, and a trapezoidal window at the rear of the vehicle into which the quarter window glass γ is fitted.

Reference numeral 8 denotes a rubber or plastic quarter window weather strip attached to the periphery of the quarter window glass 70, and a protruding piece interposed at the upper end of the quarter window weather strip 8 between the joint between the window frame 4 and the center channel 5. 9 are integrally formed.

As shown in FIG. 4, the window frame 4 has the same shape as the conventional one having a substantially convex fitting groove 11 on the side where the glass is fitted, and the center channel 5 has a cross-sectional shape, and the middle frame A bracket 10 whose tip is bent horizontally at the upper end of the portion 5a
The bracket 10 is fitted into the window frame fitting groove 11, and the horizontal part of the bracket tip is fastened to the bottom surface 11a of the fitting groove 11 with a bolt (not shown) to fix the center channel 5 to the window frame 4. I try to do that.

The quarter window weather strip 8 is a trapezoidal window frame 4 formed by a center channel 5 by fitting a groove 8a into the periphery of the quarter window glass T.
and is fitted inside the center channel 5.

A part of the corner of the upper end of the quarter window weather strip 8 on the center channel 5 side is integrally molded with the protrusion piece 9, which has an L-shaped cross section and protrudes horizontally toward the center channel 5 side (front side of the vehicle body). ing.

Two protruding pieces 9 protrude symmetrically from both ends of the weather strip 1 in the thickness direction (vehicle body left and right direction), and the vertical portions 9a of each protruding piece 9 are connected to the left and right side walls 11b of the window frame fitting groove 11. and the bracket 100, and
A horizontal portion 9b of each protruding piece 9 is interposed between the joint portion between the window frame 4 (opening peripheral portion 11c of the fitting groove) and the upper ends of the left and right frame portions 5b of the center channel 5.

Further, the tips of the horizontal portions 9b of each protruding piece 9 are bent downward and shaped so as to follow the outer surfaces of the left and right frame portions 5b of the center channel 5.

After the quarter window weather strip 8 is attached to the quarter window glass 1, the weather strip 8 is fitted into the fitting groove 11 of the window frame 4 as shown by arrow A in FIG. As shown by arrow B, the bracket 10 is inserted between the vertical parts 9a of the left and right protruding pieces 9, and the left and right frame parts 5b are inserted between the horizontal parts 9 of the protruding pieces 9.
b, and fix the bracket 10 to the window frame 4 with bolts.

In this attached state, the protruding piece 9 is interposed at the joint between the window frame 4 and the center channel 5, and prevents the two members from directly joining.

As is clear from the above explanation, according to this invention, the sealing member interposed both on the outside and inside of the joint between the window frame and the center channel is molded integrally with the weather strip. Work can be done reliably and easily without falling off or forgetting to assemble.

Furthermore, by providing the weather strip with a pair of protruding pieces that protrude both outward and inward, the following effects can be obtained.

■ Preventing rainwater, car wash water, dirt, etc. from entering the room: In other words, the inner protruding piece prevents anything that enters between the outer protruding piece and the channel (glass vertical elevating groove) from entering the room.

(2) Preventing air suction and suction noise during running; that is, the inner protruding piece reliably prevents noise from being generated in the same path as above.

- Cost reduction during automobile assembly and parts production; that is, during production, molds and machinery were required for each left and right sides, but now only -2 molds and machines are needed.

Furthermore, when assembling, there is no need to separately place the parts on the left and right sides of the vehicle, which facilitates maintenance and management, and eliminates the need for assembly errors.
