Description

  The present invention relates to a single sash side window mounted on a side of a vehicle such as a microbus or a bus, and particularly relates to a drainage structure thereof.

As shown in Patent Document 1, conventionally, in the field of side windows for vehicles, a drain hole (drain hole) is provided in the lower frame rail of the side window, and water accumulated in the rail groove is drained outside the vehicle. ing.
In this case, a check valve is provided in the drain hole.
When the bus is traveling at high speed, the passenger compartment is under a negative pressure environment.
Under such a negative pressure environment, the water level in the rail groove rises by a certain amount, and the water pressure drains outside the vehicle.
Therefore, if the allowable water level height is not sufficient, there is a risk of backflow to the vehicle interior side.
Especially in the case of a single sash window in which the glass slides directly on the lower frame, it has been impossible to secure a sufficient water level.

JP-A-8-72540

  An object of the present invention is to provide a single sash side window for a vehicle that has a simple structure and is excellent in drainage.

The present invention is a single sash side window for a vehicle, wherein the side window includes a lower frame that slides and supports a windshield and a rear glass, and the lower frame has a drainage hollow portion having a hollow cross-sectional shape; Provided at the bottom of the part where the windshield in which the window of the outer rail groove portion is closed has the outer rail groove portion on which the windshield slides and the inner rail groove portion on which the rear glass slides, on the upper side of the drainage hollow portion. The drainage piece fitted over the mounting hole provided on the bottom surface of the drainage hollow portion below the mounting hole, and the drainage piece is an upper drainage hole located at the bottom of the outer rail groove And a drainage hole located at the bottom of the drainage hollow part and a water guide space between the upper drainage hole and the drainage hole, and a bottom surface of the drainage hole located at the bottom of the drainage hollow part Has a check valve, the drainage hole provided on the bottom of said rail groove (P ₁₎ is characterized in that it communicates with the water guide space through the drainage hollow portion.
Here, as for the front glass and the rear glass, when two glasses are arranged in a sliding manner, the glass arranged on the front side in the vehicle traveling direction is called a front glass, and the glass arranged on the rear side is called a rear glass.
In the present invention, since the drainage piece is attached through the outer rail groove and the drainage hollow part below the outer rail groove, attachment work is easy.
The drainage piece is provided with a water guide space that can secure a sufficient water level, and a check valve is attached to the bottom of the drainage piece, so that water can flow from the rail groove to the inside of the compartment even under negative pressure. Prevent backflow.
In addition, the drainage piece is attached to the outer rail groove where the windshield is located with the window closed, so that the water accumulated in the inner rail groove flows into the drainage hollow through the drainage hole provided in the inner rail groove. The drainage hollow portion is drained outside the vehicle via the drainage piece.

In the case of a sliding window, the water collected in the outer rail groove and the inner rail groove may flow into the passenger compartment through the summoning section where two pieces of glass overlap. A piece is provided.
Therefore, in the present invention, a single sash side window for a vehicle, wherein the side window includes a lower frame that slides and supports a windshield and a rear glass, and the lower frame has a hollow cross-sectional shape having a hollow cross-sectional shape. And an outer rail groove part on which the windshield slides and an inner rail groove part on which the rear glass slides above the drainage hollow part, and the lower frame is a summing part of the windshield and rear glass and the summing part. A drainage hole (P ₁ ) on the front side of the outer rail groove portion and the inner rail groove portion, and the centerpiece is disposed on the front side of the drainage hollow portion. It may have a water guide space portion that communicates, and may have a drainage hole with a check valve at a lower portion of the water guide space portion.
If it does in this way, a number of parts will decrease further and assembly work nature will improve.

  In the single sash side window according to the present invention, since the water guide space and the check valve are integrally formed to secure the water level in the drain piece, the structure is simple and excellent in assemblability, Drainage is also high.
