Description

[Detailed explanation of the idea] This invention relates to a ceiling window device for automobiles.

The most important consideration in automobile ceiling window systems is the sealing performance against rainwater; since the windows are directly exposed to the air, even the slightest gap allows water to enter the passenger compartment.

For this reason, complex-shaped gutters are installed to improve sealing performance.

Therefore, providing a ceiling window significantly increases manufacturing costs.

Particularly in small cars, if a ceiling window is installed, the cost ratio of closing the ceiling window increases, making it expensive, so cars with ceiling windows are difficult to become popular.

In view of these points, this invention is an improvement to a ceiling window that is inexpensive and has good sealing properties.Hereinafter, an embodiment of the invention will be described as shown in the drawings.

A ceiling plate IK of an automobile is provided with a window hole 2, and a reinforcing piece 3 is attached around the window hole 2 to prevent a decrease in strength.

Rail fittings 4 are disposed on the right and left sides and in front of the window hole 2 along both side edges and the front edge of the window hole 2.

The rail fitting 4 has a substantially U-shaped cross section consisting of an upper frame 4as, a side frame 4b, and a lower frame 4c, and a flange portion 4d bent upward is formed at the tip of the lower frame 4c.

The upper frame 4a of the rail fitting 4 has a first seal strip 5 made of an elastic material that covers both the upper and lower surfaces of the upper frame 4a and the inner surface of the side frame 4b, and has a guide piece 5a integrally provided on the lower surface.
A second seal strip 6 made of an elastic material is also fitted to the flange portion 4d.

The second seal strip 6 is the lower frame 4c of the rail fitting 4.
The rail fitting 4 is fixed to the ceiling plate 1 by bolts 7 with the seal portion 6a interposed therebetween.

On the other hand, the edge of the ceiling window 8 is slidably inserted and supported between the top end of the second seal strip 6 and the guide piece 5a of the first seal strip 5.

Further, at the lower part of the rail fitting 4, a side frame 4b is provided. Lower frame 4cs
A quadruple water passage 9 is formed by the flange portion 4d fitted with the second seal strip and the edge of the ceiling window 8, and the water passage 9 is communicated with the outside at the lower part of the rail fitting 4. Water drain holes 10 are provided at appropriate intervals, and the seal portion 6a of the second seal strip 6 is provided with water drain holes 10 as needed.
A notch 11 is provided in accordance with 0.

Thus, the ceiling window 8 is opened and closed by sliding it along the left and right rail fittings 4.

In this case, the guide piece 5a of the first seal strip 5 is in contact with the upper surface of the edge of the ceiling window 8 to prevent rain from entering. When rainwater or the like enters the rail fitting 4 due to wear or the like, the rainwater or the like flows into the water passage 9, flows out from the drain hole 10 onto the ceiling plate 1, and the water flows into the passenger compartment side. This will be prevented.

As explained above, this device has a substantially U-shaped cross section consisting of an upper frame, a side frame, and a lower frame, and includes a rail fitting having a flange portion bent upward from the tip of the lower frame, and an upper frame. a first seal strip that is fitted into the flange portion and covers at least both the upper and lower surfaces of the upper frame, and has a guide piece on the lower surface side that guides the upper surface of the edge of the ceiling window; A water passage is formed by the side frame, the bottom frame, the button, and the flange portion into which the second seal line is fitted, and the rail metal fitting has a second seal line that supports and guides the lower surface of the edge. In order to communicate the water passage with the outside,
A drainage hole is provided to drain water from the water passage to the outside.
Water that has entered the rail fitting can escape onto the ceiling board through the drain hole, and the rail fitting also serves as a gutter to prevent water from entering the passenger compartment.

Moreover, since the seal strip and the part to be attached to the upper frame of the rail metal fitting are separate from the part to be attached to the flange part of the bottom frame, installation to the rail metal fitting is extremely easy. Rainwater, etc. in the water passage can be discharged to the outside through the drainage hole provided in the rail fitting, and there is no need to provide a gutter device on the ceiling plate side of the automobile.

Furthermore, by separating the upper and lower seal strips, the elasticity of the upper and lower seal strips can be changed, and in particular, the lower seal strip that supports the ceiling window can be made harder than the other.
