Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a back window glass mounting structure for a truck, and more particularly to a structure for mounting the back window glass at an angle with respect to a back panel.

[Conventional technology]

Conventionally, for example, in a truck type vehicle called a light truck, a back panel, that is, a passenger compartment rear wall located between a passenger compartment side at the front of the vehicle body and a luggage carrier side at the rear of the vehicle body,
It is common to provide a rear window for rear confirmation.

FIG. 2 is a side view showing a small truck having such a rear window, and FIGS. 3 (a) and 3 (b) are partially enlarged perspective views and sectional views showing details of a portion A of FIG. 2 (a). And
In the figure, reference numeral 1 is a vehicle body, and a front portion thereof is a passenger compartment 2 and a rear portion thereof is a luggage carrier 3. The reference wall X of the rear wall (back panel) 5 of the passenger compartment 2 is substantially vertical, and an opening 5a is formed in the center thereof. This opening 5a
The peripheral edge portion 5b of the base plate 5 is stepped forward with respect to the reference plane X, and constitutes a mounting surface for mounting the windshield 4b. A window glass 4b is attached to the opening 5a along the mounting surface by an elastic holding member 4a.
This constitutes the rear window 4, and the window glass mounting surface Y is substantially parallel to the reference plane X. Here, 5c is a bead formed to increase the surface rigidity of the rear wall 5, and this bead projects rearward from the reference plane X of the rear wall 5.

When performing rearward confirmation while traveling, as shown in FIG. 2B, the state of the rear portion of the vehicle can be confirmed by the rearview mirror 2 by the light a that has entered through the rear window 4.

[Problems to be solved by the invention]

However, there is a problem that the front road surface is reflected on the rearview mirror 2 by the light b reflected from the rear window 4 and the rear side is difficult to see. Therefore, the mounting angle of the windshield 4b is changed to the front view. Had to be set so that it would not appear in the rear window 4 and not block the rear view of the rearview mirror 2b. For this reason, the upper part of the entire rear wall 5 of the passenger compartment 2 is inclined forward so that the mounting surface Y of the windshield 4b is inclined to some extent. However, this causes a problem of appearance, and there is a problem that the indoor space becomes narrow as shown by the chain double-dashed line in FIG. 3 (b). Conversely, if the lower part of the rear wall 5 is inclined rearward, the size of the bed is reduced. However, the angle of the rear wall of the passenger compartment could not be tilted so much, and the effect could not be substantially improved.

As shown in FIG. 2 (b), curved glass 4b 'is used for the window glass to increase the inclination angle near the upper end of the glass, thereby greatly changing the angle of the reflected light of the light c from the front. Some have been devised to have the same effect as the rear wall being sufficiently inclined. However, such a curved glass has a higher cost than a flat glass, and has a problem that the rear visual field is distorted because it is concave.

Further, there is a flat glass having an antireflection film formed on its surface (Japanese Patent Laid-Open No. 60-93536), but in this case as well, it is necessary to perform a special treatment on the flat glass, which also leads to an increase in cost. There was a problem.

The present invention has been made to solve such a problem, and can set a large inclination angle for mounting the back window glass without significantly restricting the space of the passenger compartment and the luggage carrier, which allows expensive curved glass or reflective glass. It is an object of the present invention to obtain a back windshield glass mounting structure for a truck that can eliminate the adverse effects of reflection on the back windshield glass without using a special glass coated with a protective film.

[Means for solving problems]

A back window glass mounting structure for a truck according to the present invention has a passenger compartment in a front portion of a vehicle body, a luggage carrier in a rear portion of the vehicle body, and a back window glass in an opening portion of a rear wall having a substantially vertical reference surface of the passenger compartment. In a back window glass mounting structure for a truck, which is arranged to form a rear window, and the rear side can be confirmed through the rear window by a rearview mirror, a ridge protruding rearward from the reference plane around the opening. And forming an annular reinforcing bead, forming an additional bead between the reinforcing bead and the opening, the lower side of the additional bead is substantially the same as or lower than the reinforcing bead, the upper side Substantially coincides with the reference plane, the left and right vertical sides are inclined so that the upper portions are closer to the reference plane side, the lower edge of the opening is located in front of the additional bead, and the upper edge is in front of the reference plane. In addition to positioning, the left and right vertical side edges are inclined toward the front side toward the upper edge side to form a back window glass mounting surface having a shape in which the additional beads are substantially uniformly stepped down, and the back surface is attached to the mounting surface. It is characterized by the installation of wind glass.

[Action]

In this invention, since the back window glass mounting surface is inclined in the front-rear direction with respect to the rear wall surface by processing only the opening peripheral edge portion of the rear wall, there is no inclination of the rear wall itself. The mounting angle of the back windshield can be set to a large angle without significantly restricting the space of the room and the bed. In this case, the adverse effect of reflection on the back windshield can be eliminated without using expensive curved glass or special glass that has been subjected to antireflection treatment. Moreover, since the reinforcing bead and the additional bead are formed, the panel strength particularly near the glass mounting surface can be improved.

〔Example〕

 An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram for explaining a back window glass mounting structure for a small truck according to an embodiment of the present invention. In the figure, the same reference numerals as those in FIGS. 2 and 3 indicate the same or corresponding portions. . Here, an additional bead 6 is formed on the peripheral portion of the opening peripheral portion 5b which is stepped down in front of the passenger compartment rear wall 5. The lower side 6a of the additional bead 6 is at the same height as the bead 5c, the left and right vertical sides 6b thereof are lower toward the upper side, and the upper side 6c is substantially at the same height as the reference plane X. As a result, only the opening peripheral edge portion 5b is inclined forward,
Therefore, the mounting surface Y of the window glass 4b is inclined forward with respect to the reference surface X of the rear wall 5.

Next, the function and effect will be described.

In the window glass mounting structure of this embodiment as described above, the additional bead 6 is formed on the peripheral edge of the opening peripheral edge portion 5b without changing the inclination angle of the reference plane X of the rear wall 5, and the front surface of the wind glass mounting surface Y is formed. Since it is inclined in the direction, the space of the passenger compartment 2 as shown by the chain double-dashed line in FIG.
Alternatively, the mounting inclination angle of the window glass 4b can be set large without restricting the space of the loading platform 3. In this case, the cost of the rear window 4 can be prevented by using a general-purpose flat glass instead of the expensive curved glass or the special glass subjected to the antireflection treatment, and the problem of the distortion due to the curved surface can be avoided. Further, since the bead 6 is additionally formed in order to set the inclined wind glass mounting surface, the surface rigidity of the rear wall 5 can be further increased. Also, the height of this additional bead 6 is the original bead 5c.
Since it does not exceed the height of the room, there are no restrictions on the space in the room or the bed.

In the above embodiment, only the lower part of the opening peripheral edge 5b of the rear wall 5 is processed so as to extend rearward to change the angle of the window glass mounting surface Y. It may be processed so as to project to the front. In this case, the angle of the mounting surface can be further greatly inclined, and the adverse effect due to reflection at the rear window 4 can be eliminated more reliably.

[Effect of device]

As described above, according to the back window glass mounting structure for a truck according to the present invention, the reinforcing bead and the additional bead are provided, the lower side of the additional bead is equal to or lower than the reinforcing bead, and the upper side is the reference. The back window glass mounting surface is inclined in the front-rear direction with respect to the rear wall surface by making the opening peripheral edge step down substantially uniformly from the additional bead and inclining only the opening peripheral edge portion of the rear wall. , The back window glass can be set at a large inclination angle without significantly restricting the passenger compartment and luggage space, thereby eliminating the adverse effects of reflection on the back window glass without using expensive curved glass or anti-reflection film. There is an effect that can be achieved, and in particular, an effect that the panel strength in the vicinity of the glass mounting surface can be improved.
