Description

Description: TECHNICAL FIELD The present invention relates to a side door glass structure in which a lower glass moves up and down with respect to an upper glass fixed to a door sash of an automobile.

2. Description of the Related Art In recent years, in order to reduce running resistance, a vehicle has been developed in which a portion from a windshield glass to a side door glass is smoothly curved. The side door glass in such a vehicle employs a so-called small window type structure in which a front edge and an upper edge which are curved are fixed so that the door can be opened and closed in a narrow range excluding this portion. ing.

This side door glass is divided into an upper glass 1 and a lower glass 2 as shown in FIG. 5, for example.
When the upper glass 1 is fixed to the front side and the upper side of the door sash 3, the lower glass 2 is connected to an elevating device (not shown) in the door main body 4. The upper end comes into contact with a seal member 5 attached to the inner peripheral portion of the upper glass 1. An inner peripheral portion of the upper glass 1 and a corresponding outer peripheral portion of the lower glass 2 are formed substantially along the outer peripheral line of the upper glass 1, and a lower corner on the front end side of the upper glass 1 has a door mirror base. 6 are arranged.

This similar structure is disclosed, for example, in Japanese Utility Model Laid-Open No. Sho 58-68418.

However, in the case of the above-described conventional side door glass structure, however, the inner peripheral portion of the upper glass 1 and the outer peripheral portion of the lower glass 2 corresponding thereto are arranged so as to substantially follow the outer peripheral line of the upper glass 1. When the lower glass 2 is completely housed in the door main body 4, the front edge of the lower glass 2 naturally expands if the outer shape of the lower glass 2 is increased to increase the elevating range a. The front edge of the door body 4
Occupies a large portion of the inside of the door body and interferes with parts in the door body 4 such as a lifting device. For this reason, the elevation range a of the lower glass 2
Are greatly regulated, which hinders taking in and out of luggage.

In the above-described conventional structure, the upper glass 1
Since the door mirror base 6 is disposed at the lower corner on the front end side of the vehicle, there is a problem that the field of view of the driver diagonally forward is narrowed by the door mirror base 6.

Therefore, the present invention can extend the lowering range of the lower glass,
Moreover, it is an object of the present invention to provide a side door glass structure of an automobile capable of expanding a driver's oblique front view.

Means for Solving the Problems The present invention, as means for solving the above-mentioned problems,
A side door of an automobile having a shape curved from a front edge to an upper edge, the upper glass being fixed to a front side and an upper side of a door sash, and a lower glass being supported by a door body so as to be movable up and down. In the glass, a lower front edge of the lower glass is cut so that a horizontal cross section is substantially straight, and a lower rear edge of the upper glass is extended rearward by that amount, and a door mirror base is provided on a lower rear edge of the upper glass. Is arranged.

Action Since the lower front edge of the lower glass has less curvature, when the lower glass is lowered, it does not occupy a large amount in the width direction in the door body. Further, since the door mirror base does not cover the lower front edge of the upper glass, the driver can visually recognize the front diagonally from the lower front edge of the upper glass.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS. It is to be noted that the same reference numerals are used for the same parts as the conventional one shown in FIG.

1 to 4, in the case of the side door glass according to the present invention, the upper glass 1 and the lower glass 2 are separately formed, and the upper glass 1 is fixed to the front side and the upper side of the door sash 3. A point that the lower glass 2 is connected to an elevating device (not shown) in the door body 4 is provided with a sealing member 5 attached to the inner peripheral portion of the upper glass 1 so that the outer peripheral portion is sealed when the lower glass 2 rises. The basic structure, such as the point of contact with the member 5, is substantially the same as the conventional structure shown in FIG.

The shape of the outer peripheral portion of the lower glass 2 is simply formed along the outer peripheral line of the upper glass 1 in the case shown in FIG. 5, but in the case of the side door glass according to the present invention, the lower front edge of the lower glass 2 is formed. 3, the horizontal section of the lower glass 2 is formed so as to be substantially straight as shown in FIG. 3, while the vertical width of the lower glass 2 is extended to extend the elevation range a. . And
The inner shape of the upper glass 1 is the lower glass 2.
And a door mirror base 6 is arranged on the lower rear edge corresponding to the front end of the lower glass 2. The door mirror base 6 has a sealing member 5 at the lower rear edge of the upper glass 1.
Abut.

In the figures, reference numerals 7 and 8 denote a Hundt pillar and a windshield glass whose outer surfaces are smoothly connected to the side door glass, and 9 denotes a roof.

In this side door glass, the curved portion of the lower glass 2 is cut so that the horizontal cross section is substantially straight. Therefore, even if the vertical width of the lower glass 2 is increased, the front end portion of the lower glass 2 is closed when the lower glass 2 descends. A trouble such as interference with components in the main body 4 does not occur. As a result, the elevation range a is greatly expanded as compared with the conventional one shown in FIG.

In addition, since the door mirror base 6 is not provided at the lower corner A on the front end side of the lower glass 2, the driver can visually recognize the front diagonally from the lower corner A.

Advantageous Effects of the Invention As described above, according to the present invention, the lower front edge of the lower glass is cut so that the horizontal cross section is substantially straight, and the lower rear edge of the upper glass is extended backward by that amount, Since the width of the lower glass occupied in the door main body is reduced, the range in which the lower glass can be raised and lowered can be extended without the lower glass interfering with the components in the door main body.
In addition, a door mirror base is arranged on the lower rear edge of the upper glass so that the driver can visually recognize the front diagonally from the lower front edge of the upper glass, so that the driver's oblique front view can be compared to the conventional one. Spread reliably.
