Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window device that is slidable in the direction of travel of an automobile.

There are various types of windows installed in automobiles, such as those that open and close vertically, those that slide back and forth, and those that rotate. Among these types, in the sliding type in the front and rear, that is, in the direction of travel of the vehicle, if acceleration is applied in that direction, there is a risk that the window glass will slide due to this acceleration. In particular, if you brake suddenly while driving, the windshield that was open will suddenly close due to the large acceleration that is applied.
There is a risk of your hands being pinched. Conventionally, the sliding resistance of the window glass was increased to prevent the window glass from closing abruptly. However, such a conventional window glass has a problem in that its sliding resistance makes it difficult to open and close, impairing operability.

In view of these problems, the present invention is designed to prevent the sliding movement of the sliding windshield in the direction of travel of the vehicle when sudden braking is applied without impairing operability. The purpose of this invention is to provide a device that can achieve the desired results.

An embodiment of the present invention will be described below with reference to the drawings.
In this embodiment, the present invention is applied to a window provided on the door of the driver's cab of a large truck.
As shown in FIG. 1, the door 1 of the driver's cab is configured to be vertically long, and a see-through window 2 is formed at the lower side of the door 1 to confirm the visibility of the lower side. Further, a pair of window glasses 3 and 4 are provided in the window on the upper side of the door 1. These window glasses 3, 4 are supported by a frame 5, and cannot be moved downward due to the provision of the see-through window 2, so that they can be slid in the front-rear direction, that is, in the direction in which the vehicle is running.

A stopper plate 7 is fixed to the lower part of the window frame 6 of the front window glass 3 of the pair of window glasses 3 and 4, as shown in FIGS. 2 and 3. Serrated teeth 8 are formed on the lower surface of the stopper plate 7. An engagement plate 1 having teeth 9 opposing teeth 8 of this stopper plate 7
0 is arranged at the lower part of the stopper plate 7, and is fixed to the tip of the lever 11. This lever 11 is supported so as to be rotatable about a pin 12, and is biased by a compression coil spring 13 to rotate counterclockwise in FIG. 2 about the pin 12.

Furthermore, an iron piece 14 is fixed to the upper surface of the lever 11. This piece of iron 14 is constructed so that it can be attracted by an electromagnet 15. The electromagnet 15 is fixedly supported by a support plate 17 fixed to a case 16 housing the lever 11. Further, the case 16 is supported by a door outer panel 18. Note that the door outer plate 18 is arranged at a predetermined distance from the door inner plate 19, and is joined at the end to form the door 1.

The frame 5 is attached to the outer panel 18 of this door 1.
is fixed, and the rail 20 of this frame 5
The window glass 3 is slidably supported by. Also, in this frame 5, especially the third
As shown in the figure, an opening 21 is formed that allows the engagement plate 10 to move up and down. Further, a rubber weather strip 22 is attached to the lower surface of the frame 5.

A lead wire drawn out from the coil of the electromagnet 15 is connected to a battery power source 24 via a switch 23, as shown in FIG. switch 2
3 is disposed below the brake pedal 25 in the driver's cab, and is closed when the brake pedal 25 is stepped on.

In the above configuration, when the brake pedal 25 is depressed while the vehicle is running, the switch 23 is closed and power is supplied from the power source 24 to the electromagnet 15. As a result, the iron core of the electromagnet 15 becomes the iron piece 1
Adsorb 4. For this purpose, the lever 11 rotates clockwise in FIG. 2 about the pin 12 against the compression coil spring 13. Then, the engagement plate 10
moves upward through the opening 21 of the frame 5;
As shown by the chain line in FIG.
The teeth 9 of the stopper plate 7 and the teeth 8 of the stopper plate 7 mesh with each other. Therefore, the window glass 3 to which the stopper plate 7 is attached is prevented from sliding and is locked in the open position. Therefore, even if the brakes are applied suddenly, the window glass 3 will not suddenly move in the direction of closing due to acceleration. This prevents hands or the like from being caught between the window glass 3 and the frame 5.

Next, a modification of the above embodiment will be explained with reference to FIG. In this modification, a stopper plate 29 having a bent piece 28 is attached to the lower part of the window glass 3, and a stopper plate 31 having a rubber brake shoe 30 fixed to the upper part is arranged at the lower part of the stopper plate 29. ing. The blocking plate 31 is supported on a support plate 34 by a pair of links 32 and 33. The link 32 is connected to a piston rod 36 of an air cylinder 35 by an elongated hole 37 and a pin 38.

Therefore, when the detection switch is closed in conjunction with depression of the brake pedal, for example, the air cylinder 3
A solenoid valve for supplying compressed air to the air cylinder 35 is opened, and compressed air is supplied to the air cylinder 35. Thus, the piston rod 36 is retracted into the cylinder 35, and the links 32, 33 rotate as shown by the chain lines in FIG. As a result, the blocking plate 31 moves upward, and the brake shoe 30 fixed to the blocking plate 31 is pressed against the lower surface of the bent piece 28 of the stopper plate 29, thereby preventing the window glass 3 from sliding. It turns out. Therefore, when the brakes are applied suddenly, the window glass 3 will not close automatically due to acceleration.

Although the present invention has been described above with reference to embodiments, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiment, the present invention is applied to a large truck, but the present invention can also be applied to buses and other automobiles.

As is clear from the above, according to the present invention, when the detection means detects the operation of the brake, the blocking means interlocks with this and prevents the sliding of the window glass. When the brakes are applied suddenly, the windshield will no longer automatically slide due to acceleration, and there will be no chance of hands or the like being caught between the windshield and the frame. It is therefore possible to provide a risk-free motor vehicle window device. Further, by providing the blocking means, the sliding resistance of the window glass can be kept small, so that the windshield does not become heavy when normally opened and closed, and operability is not impaired.
