Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding window mounted on a vehicle such as a bus. More specifically, the present invention relates to a drainage structure of a sliding window for a vehicle for discharging water stored in a lower rail of the sliding window.

[0002]

2. Description of the Related Art A conventional rail under a sliding window for a vehicle is
As shown in FIG. 4, a drainage hole 3 is provided at the bottom of the lower rail 2, and a valve 8 made of an elastic body capable of opening the drainage hole 3 is provided at a part of the lower peripheral edge of the drainage hole 3. It is glued. A guide plate 4 inclined toward the outside of the vehicle is provided below the lower rail 2 so that the water dropped from the water drain hole 3 is guided to the outside of the vehicle through a drain hole 9. According to this structure, the rainwater 5 stored on the lower rail 2 pushes the valve 8 by its own weight as shown by the broken line in FIG. 4 to fall on the guide plate 4 provided at the lower part, and from the drain hole 9 is indicated by a solid arrow. As shown, it can be discharged by being guided outside the vehicle. In addition, from the outside of the vehicle through the drainage hole 9
When the wind tries to flow in as shown by the broken line,
Prevents the inflow of wind by closing the drain hole 3 with the wind pressure.

As another conventional example, a structure in which a valve made of a resin-molded elastic body is mounted in the drainage hole of the lower rail is also disclosed (Shokai 61-158509).
According to this structure, although the same effects as those of the above-mentioned conventional example are exhibited, it is possible to eliminate the variation in the bonding work and to facilitate the valve mounting work.

[0004]

However, in the structure in which the lower rail is provided with the water draining hole and the valve is provided at the lower peripheral edge thereof, the size of the water draining hole is limited due to the space for installing the valve, and the size of the dust is reduced. However, there is a drawback that foreign matter such as dust is easily caught, and that if foreign matter such as dust is caught in the valve, the valve does not function sufficiently and air flows in. In addition, since the valve made of an elastic body is weakened due to aged deterioration after long-term use and loses its elastic force and does not function as a valve, there is a problem that water in the lower rail cannot be sufficiently drained. Further, in a structure in which a valve formed of resin is mounted, there is a risk that water may remain in the lower rail without being completely drained from the drain hole due to a step difference in the flange portion of the molded body. An object of the present invention is to provide a drainage structure for a sliding window for a vehicle, which does not affect the drainage performance even if foreign matter enters, and can further improve the drainage performance.

[0005]

A configuration of the present invention for achieving the above object will be described with reference to FIG. 1 corresponding to an embodiment. The present invention is directed to a vehicle puller in which a drainage hole 13 is provided in a lower rail 12 of a sliding window for a vehicle, and a guide plate 12d is provided below the lower rail 12 to guide water dropped from the drainage hole 13 to the outside of the vehicle. It is an improvement of the drainage structure of the difference window. The characteristic configuration is that the guide plate 12d is provided with the drain hole 14, the lower portion of the guide plate 12d is provided with a water receiver 16 for receiving the water discharged from the drain hole 14, and the water receiver 16 stores the water in the water receiver 16. A discharge port 17 for discharging water to the outside of the vehicle and a valve 18 for opening and closing the discharge port 17 are provided. The valve 18 is opened by gravity when water is stored in the water receiver 16 and is closed when air flows in from the outside of the vehicle through the discharge port 17. It has been configured as follows.

[0006]

When the lower rail 12 collects water, the water drops from the water draining hole 13 to the guide plate 12d and is carried to the drain hole 14 by the guide plate 12d.
Is stored in. The water stored in the water receiver 16 pushes the valve 18 open by its own weight and is discharged from the vehicle through the discharge port 17. When the air flows into the discharge port 17 from the outside, the valve 18 closes the discharge port 17 by the wind pressure.

Since the water outlet is provided in the water receiver, the water drop can be increased as compared to the conventional case, and as a result, the water accumulated on the lower rail can be smoothly discharged to the outside of the vehicle. In addition, a valve that opens and closes the outlet is provided, and the valve opens when water accumulates in the water receiver, and the valve closes when air flows from the outside of the vehicle through the outlet. Even so, the valve blocks the exhaust port due to the wind pressure, and the wind does not flow into the vehicle.

Further, since the valve is provided in the water receiver, the conventional valve made of an elastic body is not used, so that there is no limitation on the size of the water drain hole, and the capacity of the water drain hole, the drain hole and the water receiver can be increased. If it is made large, it is possible to prevent foreign matter from being caught. Further, since the valve is opened and closed without depending on the elasticity of the resin, a steel material can be used. As a result, the drainage property can be further improved, and the drainage property does not change over a long period of time.
