Description

[Detailed Description of the Invention] This invention relates to a door for a cab-over truck.

In cab-over trucks, part of the visibility through the door window on the assistant seat side relies on indirect visibility using the rear view mirror or under mirror.

Additionally, in order to expand direct visibility, it is effective to make the door window larger and lower the upper edge of the door body.
Considering the retractability of the door glass, there is a limit to the size of the door window.

This idea was made in view of the conventional situation, and the front upper window was opened in a position corresponding to a conventional triangular window, making use of the space in front of the tire grip formed in the door. At the same time, a front lower window is installed in the area where the glass is stored, and a rear upper window and a rear lower window are installed above the tire sleeves to improve ventilation, ease of entry when reversing, etc. The aim is to expand the direct visibility down the side of the assistant seat side without sacrificing too much.

Hereinafter, this invention will be explained in detail based on an embodiment shown in the accompanying drawings.

In the figure, reference numeral 1 denotes a door that is attached to the side surface of a cab 3 so as to be openable and fixed via a door hinge, 2, and a door lock (not shown), and a tire lining 4 is formed at the lower part of the door.

5 is a front upper window opened at the front upper part of the tire clip 4; 6 is the front of the tire sleeve 4 from the lower edge of the front upper window 5 (near the lower end of the door 1);
Front lower windows opened over 7 and 8
are a rear upper window and a rear lower window that are opened above the tire clip 4, and these windows are connected to a horizontal door sash 9 that connects approximately the center of the front and rear frames of the door 1 and the tire sill 4. A vertical door sash 10 connects the upper and lower frames of the door 1 near the front end of the door 1, and a reinforcing member (not shown) is fixed in the horizontal door sash 9 to maintain the strength and rigidity of the door 1.

11 is a door handle provided near the rear end of the horizontal door sash 9.

It goes without saying that the door hinge 2 and the door lock (not shown) are connected to a reinforcing member fixed to the horizontal sash 9.

Reference numeral 12 denotes a pinion mounted on a shaft at the intersection of the door sashes 9 and 10, and is rotatably controlled in either forward or reverse directions by a regulator handle 13 provided on the inner surface of the door 1.

This pinion 12 is meshed with a rack 14 which is attached to the vertical door sash 10 so as to be able to rise and fall freely.
A glass 5' is connected to cover the parts so as to be openable and closable.

The glass 5' is moved up and down along a glass run (not shown) attached to the front frame of the door 1 and the vertical door sash 10.

6', 7', and 8' are glasses that are fitted tightly into the front lower window 6, rear upper window 7, and rear lower window 8, and cover the windows 6, 7, and 8, respectively. For example, the rear upper window 7 may be opened and closed by rotating the glass 7' covering the rear upper window 7 about a vertical axis (not shown).

In the door of the cab-over truck constructed as described above, the front lower window 6 and the rear lower window 8 are opened in the part that was conventionally constructed of sheet metal, so the glass of both lower windows 6 and 8 is Through this, you can directly see the lower side of the assistant seat side.

In addition, since the space in front of the tire 4 (front lower window) can be used to lower and store the glass 5' that covers the front upper window 5, the front upper window 5 can be fully opened, providing ventilation and It is possible to ensure the stability of time.

Furthermore, since the glass 5' which covers the front upper window 5 in an openable and closable manner is connected to the rack 14 moving along the vertical door sash 10 in this manner, the opening/closing mechanism is simplified and the opening/closing mechanism is simplified. Since the opening/closing mechanism (rack) can be located within the range of the door cache 10, the appearance of the door is not impaired.
In addition, there is no risk of visibility being obstructed by the opening/closing mechanism.In short, with the door according to this invention, the sheet metal part of the door can be made as small as possible to expand the area of the window, which improves ventilation, ease of entry when reversing, etc. Direct visibility down the side through the door can be greatly expanded without sacrificing much.

Furthermore, since the rack moves linearly, there is no need to provide a link mechanism or the like, which simplifies the opening and closing mechanism.
