Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a side door with a lower window for medium-sized and large-sized trucks.

[Prior art] In conventional medium-sized and large-sized trucks, the driver could not see the front lower part of the side of the vehicle through the opening/closing window of the left side door, so pedestrians were often caught when the truck turned left. I was afraid. Therefore,
In recent years, improvements have been made in which a lower window is provided below the opening/closing window of the left side door so that the driver can visually check whether there are pedestrians near the left side of the vehicle through this lower window.

A structure in which a reinforcing rod is provided across the lower window of a side door is disclosed in, for example, Japanese Utility Model Application Publication No. 163219/1983. It is desirable that the lower window of the side door on the left side of the vehicle be as wide as possible in order to improve the driver's visibility, but if the lower window is enlarged, the strength of the door will decrease and the insulation properties of the window glass will be poor. , there is a problem that the heating and cooling effect of the vehicle compartment is impaired.

[Problems to be solved by the invention] The purpose of the invention is to maintain the strength of the door and improve the heat insulation effect by attaching the inner window glass to the inside of the conventional lower window window glass via reinforcing rods. The objective is to provide a side door for the truck.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the present invention is such that an opening for partitioning the lower window placed below the opening/closing window of the door is provided in the outer panel of the door and the inner panel of the door. The edge of the opening in the door inner panel is bent so that the cross section of the opening is tapered to form an opening wall, and then combined with the edge of the opening in the outer door panel, and the outer window is attached to this joint. The glass is attached, a reinforcing rod that crosses the opening is connected to the opening wall of the inner door panel, and the engaging member connected to the inner window glass is engaged with the reinforcing rod to fit the inner window glass to the opening wall. This is what happens.

[Function] The edge of the opening that partitions the lower window of the door inner plate 7 is bent so that the cross section of the opening is tapered to form the opening wall 7a, and the edge of the opening wall 7a is connected to the outside of the door. The outer window glass 4 is attached to the joining part of the plate 8 to the edge of the opening.
is attached and the inner window glass 9 is fitted to the opening wall portion 7a, so the opening is closed by a double window glass, improving heat insulation and heating and cooling effects.

Since the reinforcing rod 5 is connected to the opening wall portion 7a, the strength of the door is maintained even if the opening area of the lower window is increased.

[Embodiment of the invention] As shown in FIG. 1, the left side door 2 of a large truck is equipped with a normal opening/closing window or upper window 3 and a lower window represented by an outer window glass 4. The lower window is closed by an outer window glass 4. A reinforcing rod 5 that crosses the lower window is fixed to the opening wall 7a of the opening 17 by a bracket 6.

As shown in FIG. 2, the edge of the opening 17 of the door inner plate 7 is bent so that the cross section of the opening is tapered to form an opening wall 7a, and the edge flange 21 of the opening wall 7a and the door The edge flanges of the opening in the outer panel 8 are joined together in an overlapping manner. The outer window glass 4 is supported at this joint portion via the windshield 15. Such a configuration is similar to the conventional one.

According to the present invention, the reinforcing rod 5 that crosses the opening is coupled to the opening wall 7a, and the inner window glass 9
is fitted. Therefore, as shown in Figure 1,
A windshield 12 made of an elastic material such as rubber is coupled to the peripheral edge of the inner window glass 9, and the windshield 12 is fitted into the opening wall 7a.
At the same time, an engaging member 10 coupled to the inner window glass 9
is engaged with the reinforcing rod 5.

As shown in FIG. 3, the engagement member 10 is made by bending a long and thin metal plate into a substantially U-shape, and has elastic engagement pieces 13 integrally formed on both ends. The center portion of the engaging member 10 is overlapped with the inner window glass 9, and is fixed by inserting the bolt 16 from the inside and tightening the cap nut 14 from the outside. The elastic engagement pieces 13 of the two engagement members 10 attached to the inner window glass 9 are engaged with the reinforcing rods 5, whereby the windshield 1
2 is maintained in close contact with the opening wall portion 7a.

In the embodiment shown in FIG. 4, the engagement member 10 is a long and narrow plate bent into a U-shape, and both ends 10a are folded back in a direction that separates them from each other. Engagement member 1
The central portion of the U-shaped reinforcing rod 5 is engaged with the reinforcing rod 5, and preferably fixed by welding or the like.
Both ends 10a of the engaging member 10 are overlapped with the inner window glass 9 and fastened with bolts 19 and nuts 20.

Note that using a synthetic resin plate such as acrylic resin instead of the inner window glass 9 helps ensure the safety of passengers getting on and off the vehicle.

[Effects of the invention] As described above, the present invention provides openings on the door outer panel and the door inner panel to partition the lower window placed below the opening/closing window of the door, and the edge of the opening on the door inner panel The opening wall section is formed by bending the edge so that the cross section of the opening is tapered, and then it is joined to the edge of the opening on the outer panel of the door, and the outer window glass is attached to this joint, and the opening on the inner panel of the door is bent. Connect the reinforcing rod across the opening to the wall,
Since the engaging member connected to the inner window glass is engaged with the reinforcing rod and the inner window glass is fitted into the opening wall, it can be easily attached to conventional side doors, and the lower window can be double-layered inside and outside. Because it is closed by the window glass of
The heating and cooling effect of the driver's cabin is enhanced.

Since the reinforcing rod that crosses the lower window is connected to the opening wall, the strength of the door is maintained even if the opening area of the lower window is widened. Furthermore, since the reinforcing rod is engaged with the engagement member of the inner window glass, the state in which the inner window glass is fitted to the opening wall portion is maintained.
