Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle door with a lower window.

[Conventional technology]

For example, in the cabin of a truck, conventionally, as shown in the front view of FIG.

Here, when the handle 02 is rotated, the inclined link 07 having the arcuate rack 04 at the lower end via the pinion 03 and the upper end roller fitting with the upper guide rail 06 of the window glass 05 is rotated around the central fulcrum 08 thereof. It rotates and the same fulcrum 08
The central part is pivotally supported and the upper and lower ends are the upper guide rails 0
6, The window glass 05 moves up and down by the cooperation with the other tilted link 010 fitted to the lower guide rail 09 of the door panel via the roller.

However, with such a door with an upper window, it is not possible to visually recognize the lower portions of both front ends of the body from the driver's seat. Especially, in a truck, the left door has a relatively large lower window for safe driving when turning left. Has become necessary.

By the way, in the door with the upper window shown in FIG. 4, if the lower window is provided on the door panel, there is a problem that it interferes with the elevating mechanism of the window glass. Therefore, as shown in FIG.
A structure in which a lower window is provided on a sliding door of the upper window is also proposed.

However, in the slide type glass, the opening width is about half that of the elevating type glass, which is narrow, which is inconvenient when the driver wants to get his head out of the window.

Therefore, in the structure shown in the figure, if the upper window is of an elevating glass type, the elevating mechanism will be located at the rear of the lower window, and the glass will eccentrically exert a load during elevating, so the glass can slide smoothly. Special support is required to support and move.

[Problems to be solved by the device]

The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a vehicle door with a lower window having an upper window of an elevating glass and a relatively large lower window.

[Means for Solving the Problems]

To this end, the present invention relates to a vehicle door having an upper window in the upper half of the door panel and a lower window in the front half of the lower half of the door panel. Vertical guide rails whose upper and lower ends are supported on the upper and lower ends of the window frame, upper and lower pulleys respectively arranged on the upper and lower ends of the guide rails, and fixed parts to the rear end of the lifting glass. By moving a pair of upper and lower rollers that can be moved along the guide rails and a wire that is disposed around the door panel and is wound around the pair of upper and lower pulleys around the guide rollers. It is equipped with a wire regulator that moves up and down.

[Action]

Although the front and rear ends of the elevating glass are guided along the front and rear run channels, respectively, in the present invention, a pair of upper and lower parts are provided so as to project from the corners of the horizontal upper edge and the edge immediately after the lead. The guide roller of is slidably supported along the vertical guide rail fixed to the door panel.

Therefore, in the elevating glass, the moment due to the gravity acting on the center of gravity and the moment due to the reaction force that the pair of upper and lower rollers receive from the vertical guide rails are balanced, so that the wire regulator mechanism does not tilt even though it is eccentrically arranged. , It can go up and down smoothly.

Since the wire regulator is attached to the rear of the door panel, a relatively large lower window can be provided at the front of the door panel without interfering with the wire regulator mechanism.

[Embodiment] An embodiment in which the present invention is applied to a truck will be described with reference to the drawings. FIG. 1 is a front view thereof, and FIG.
FIG. 3 is a horizontal sectional view taken along line II, and FIG. 3 is an explanatory view showing the internal structure of FIG.

In the above figure, 1 is an elevating glass that forms an upper window, 2 is a relatively large smashing glass that forms a lower window, 3 extends vertically along the rear pillar, and the upper and lower ends are respectively the upper and lower rear ends of the window opening. Guide rails 5 having a square C-shaped cross section fixed via a trim 4 are a pair of upper and lower guide rollers fixed to the lower end of the elevating glass 1 via a mounting plate 6, and both guide rollers 5, 5 Is inserted in the guide rail 3.

7 and 8 are a pair of upper and lower pulleys pivotally attached to the upper and lower ends of the guide rail 3, 9 is a regulator handle attached to the inner side of the door panel, 10 is one end fixed to the mounting plate 6, and the middle part is the pulley 7. After passing through the pulley of the regulator handle 9 several times, the other end is fixed to the mounting plate 6 via the pulley 8.

In such a structure, when the regulator handle 9 is rotated clockwise, the wire 11 is moved clockwise, so that the mounting plate 6, that is, the lifting glass 1 is moved downward, and when it is rotated counterclockwise, the lifting glass is moved. To rise.

At that time, the lifting glass 1 is a pair of upper and lower guide rollers 5,5.
Since it is supported so that it can only be moved up and down along the guide rails 3 via the guide rail, it can be smoothly moved even if the position of the guide roller is largely displaced rearward with respect to the center of gravity of the lifting glass. Can be raised and lowered.

Also, since the guide rails, guide rollers, regulators, etc. are eccentrically arranged near the rear end of the door panel, the lower front part of the elevating glass 1 is a lower window of a large-sized fitting glass that covers more than half of the door width. Can be provided.

It is desirable that the guide rail 3 be hidden by applying a ceramic coating 12 to the portion of the inner surface of the elevating glass 1 near the rear end.

[Effect of device]

In short, according to the present invention, a vehicle door having an upper window in the upper half of the door panel and a lower window in the front half of the lower half corresponds to the position of the upper window near the rear end of the elevating glass. Vertical guide rails whose upper and lower ends are respectively supported on the upper and lower ends of the window frame, upper pulleys and lower pulleys respectively arranged on the upper and lower ends of the guide rails, and a portion near the rear end of the lifting glass. A pair of upper and lower rollers that are fixedly attached and can move along the guide rail, and a wire that is disposed around the door panel and that is wound around the pair of upper and lower guide rollers around the upper and lower pair of pulleys. The present invention provides a door for a vehicle with a lower window, which has an upper window of an elevating glass and a relatively large lower window by including a wire regulator that is moved up and down by Those above extremely beneficial.
