[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a mounting structure for a center sash in a sliding window for a vehicle.

[Conventional technology]

For example, as described in Japanese Patent Publication No. 57-36167, an inner glass and an outer glass are slidably fitted into a glass run fitted inside a window frame, and both A center sash is erected in the middle of the glass wrap portion in a manner that spans between the upper and lower frames of the window frame, and a weather strip is provided at the outer side end of the center sash so as to be able to come into sliding contact with both the inner glass and the outer glass. A sliding window for a vehicle has been proposed that is configured to prevent rainwater or the like from entering the vehicle interior through the wrap portion by attaching the wrap portion. The structure of a conventional vehicle sliding window is shown in Figure 1 below.
This will be explained based on FIGS. 2 and 6. Figure 1 is an overall view of a typical sliding window for a vehicle as seen from the passenger compartment side, and Figure 2 is a -
It is a figure corresponding to a line enlarged cross section. Further, FIG. 6 is a view corresponding to a cross section taken along the line - in FIG. 2 of a conventional sliding window for a vehicle. As shown in FIG. 2, grooves 12 and 13 having a substantially cylindrical inner surface are provided along the respective edges of the vehicle outer end 9 and the vehicle inner end 11, and the grooves 12 and 13 are provided at the vehicle outer end 9. A weather strip 10 having a substantially V-shaped cross section is formed in the groove 12 so as to be able to come into elastic contact with both the inner glass 3 and the outer glass 4.
It is attached by fitting the base 14 thereof. Moreover, the center sash 8 has a pair of screw holes a, which are drilled in the upper frame 6, as shown in FIG.
A pair of screws d and c inserted from the outside of the upper frame 6 through b are inserted into both ends 9 and 11 of the center sash 8.

[Problem that the idea aims to solve]

However, when the above structure is adopted, the distance between the inner glass 3 and the outer glass 4 is narrow as shown in FIG. The balance of the elastic abutting forces on each of the glasses 3 and 4 may be disrupted, and the sealing performance of one of the glasses may deteriorate. Also, as mentioned above, weather strip 1
When an external force is applied to the inner glass 3 or the outer glass 4 in a state where the elastic contact force of 0 is unbalanced, the center sash 8 is moved against the upper and lower frames 6 and
Since the weather strip 10 is fixed by a pair of upper and lower screws d and c, the impact force cannot be absorbed at the glass abutting portion of the weather strip 10, and the center sash 8 or the inner and outer glasses 3, 4 cannot absorb the impact force. damage may occur. Therefore, it is necessary to attach the center sash 8 to the upper and lower frames 6, 7 with high precision, and there is a problem that the installation workability is extremely poor. Further, as shown in FIG. 6, since the tip of the screw c comes into contact with the upper end 10a of the weather strip 10, the weather strip 10 cannot be inserted to the inside of the upper frame 6. Therefore, a gap 24 is created between the upper end 10a of the weather strip 10 and the upper bottom 2a of the glass run 2.
There is a problem that rainwater and the like enter the vehicle interior from the vehicle interior. Further, in order to minimize the gap 24, it becomes necessary to adjust the insertion position of the weather strip 10, and there is also the problem that the workability of installing the weather strip 10 is poor. The present invention was devised under the above-mentioned circumstances, solves the above-mentioned conventional problems, and has a simple structure that allows the weather strip 10 to have inner and outer glass 3,
A center sash that can prevent the balance of the elastic contact force against the center sash 8 and the weather strip 10 from being unbalanced, prevent rainwater etc. from entering the vehicle interior, and improve workability for installing the center sash 8 and the weather strip 10. The task is to provide a mounting structure.

[Means for solving the problem] In order to solve the above problem, in the present invention,
The following technical measures have been taken: That is, in the present invention, the inner glass 3 and the outer glass 4 are fitted into the glass run 2 fitted inside the window frame 1 so as to be able to slide against each other in a sliding manner, and both the glasses 3, 4 In a sliding window for a vehicle in which a center sash 8 is erected between the upper and lower frames 6 and 7 of the window frame 1 in the middle of the wrap portion 5 of the window frame 1, the outer side end 9 of the center sash 8 is Grooves 12 and 13 are provided along the entire length of the inner end 11 of the weather strip, and the base 14 of the weather strip 10 is fitted over almost the entire length of the groove 12 of the outer end 9 of the vehicle. The helical shaft portion 23 of the screw 23 protrudes from the screw hole 22 provided in the upper and lower frames 6, 7 of the window frame 1 in the groove 13 of the portion 11.
The center sash 8 is swingably fixed to the window frame 1 by screwing in the center sash 8.

[Functions and effects of the idea]

The present invention improves the sealing performance between the inner glass and the outer glass by swingably fixing the center sash to the upper and lower frames of the window frame with one screw each on the upper and lower sides. This also improves installation workability. Conventionally, the center sash that holds the weather strip, which is located between the inner glass and the outer glass and seals between the inner glass and the outer glass, is immovable relative to the upper and lower frames by a pair of screws at the top and bottom. It was fixed to. As a result, if the mounting accuracy deteriorates, the balance between the elastic contact forces of the weather strip against the inner and outer glass is lost, resulting in a decrease in sealing performance and even damage to the center sash or glass. In the present invention, the weather strip is attached to the inner glass and the outer glass by fixing the center sash with one screw each on the top and bottom and allowing the center sash to swing around the screws. Even if the mounting accuracy of the center sash is reduced, it is possible to prevent the sealing performance from deteriorating.
Furthermore, since the mounting structure of the center sash has a flexible structure, it is possible to absorb shocks caused by external forces, and damage to the center sash or the glass can be prevented. Furthermore, even if the mounting accuracy of the center sash is reduced, the center sash can swing around the screw to the appropriate position and balance the elastic contact force against the inner and outer glass of the weather strip. The installation of the sash no longer requires the same precision as in the past, and the installation work efficiency is greatly improved. Furthermore, in the present invention, since the screw is screwed only into the inner side end of the center sash, the weather strip can be inserted to the inside of the upper and lower frames at the outer side end, unlike the conventional example. There is no gap between the upper end of the weather strip and the bottom of the glass run, and there is no risk of rainwater or the like entering the vehicle interior. Further, there is no need to adjust the insertion position of the weather strip, and the workability of attaching the weather strip is improved.
