DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass raising / lowering structure of a vehicle door having a door sash.

[0002]

2. Description of the Related Art A press type front side door 1 is shown in FIGS.

The front side door 1 comprises a door body 2 in which a door glass G is stored and a door sash 3 forming an opening of the door glass G.

A channel material 4 is attached to the periphery of the opening of the door sash 3 on the inner panel 3a and the outer panel 3b constituting the door sash 3.

A glass run 5 for holding the periphery of the door glass G is attached to the channel member 4.

[0006] Here, the door sash portion 3 comprises a front side portion 3A, an upper side portion 3B, and a rear side portion 3C.

A glass run 5 having a constant cross-section is attached to each of the front side portion 3A and the upper side portion 3B by a molding part, and the rear side portion 3C is a rear edge of the door glass G and a door glass G. Is formed along the ascending and descending trajectory line P (indicated by a dashed line in the figure). Here, a glass run 5 having a constant cross-sectional shape is used, and the glass run 5 of the upper portion 3B is continuously attached to the mold run portion (not shown). is there. The rear edge of the glass run 5 is indicated by a two-dot chain line Q.

[0008]

However, in the above-described conventional door glass lifting / lowering portion structure, as shown in FIG. 6, when the opening of the door glass G is formed into a round shape for reasons of molding. In addition, since the rear edge of the door glass G has a linear shape, the glass run 5 attached to the rear side 3C of the door sash 3 does not have a constant cross-sectional shape. Must be done, resulting in high costs.

That is, in the front side portion 3A and the upper side portion 3B of the door sash portion 3, a glass run (not shown) curved corresponding to the front side edge and the upper side edge of the door glass G can be used. An extrusion molded product can be used by keeping the wrap margin of the glass run 5 constant at the rear side portion 3C of the door sash portion 3 (see FIG. 6 (shown by a two-dot chain line) is a linear shape, so that an extruded product cannot be used.

When the rear edge Q of the glass run 5 is formed along the arc R of the front edge of the rear portion 3C of the door sash portion 3, as shown by a dashed line in FIG. Although it can be used, the door sash portion 3 corresponds to the width L of the glass run 5 curved outward.
The rear edge of the rear side portion 3C retreats, the width of the rear side portion 3C of the door sash portion 3 increases from X to W, and the appearance deteriorates.

Therefore, the present invention can reduce the cost,
Another object of the present invention is to provide a door glass elevating / lowering portion structure that can improve the appearance.

[0012]

SUMMARY OF THE INVENTION In a vehicle door provided with a door sash, a rear edge of a door glass is moved upward and downward.
It is formed in an arc shape so that the approximate middle is the rearmost end, and
When Agulhas is fully closed ,
On the other hand, the part below the rear end forms a gap
Together constitute a, is formed in an arc shape so as to follow the front edge of the rear side of the door sash to rear edge of the door glass.

[0013]

The use of a glass run having a constant cross-section, wherein at least a part of the rear edge of the door glass is formed in an arc shape, and the front edge of the rear portion of the door sash is formed parallel to the rear edge of the door glass. And reduce the width of the rear side of the door sash.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. The same parts as those in the conventional configuration are denoted by the same reference numerals.

1 to 3, reference numeral 1 denotes a press type front side door. The front side door 1 is a door body 2 in which a door glass G is stored and a door sash forming an opening of the door glass G. And the door sash section 3 of FIG.

The periphery of the opening of the door sash 3 is formed in a rounded shape, and the periphery of the opening is formed with a channel in the inner panel 3a and the outer panel 3b constituting the door sash 3 as shown in FIG. Material 4 is attached.

The door sash portion 3 includes a front side portion 3A and an upper side portion 3A.
B and the rear side 3C, and the channel material 4
Is equipped with a glass run 5.

Here, the rear edge GB of the door glass G
Has an arc shape such that the middle of the vertical direction is the rearmost end X.
When the door glass G shown in FIG. 1 is fully closed,
With respect to the elevating locus line P drawn by the end X, the end X
The portion below the bridge forms a gap Z.

Further, a rear side portion 3C of the door sash portion 3 is provided.
Is formed in an arc shape (radius R) parallel to the rear edge GB of the door glass G.

According to the structure of the above embodiment, the rear edge GB of the door glass G and the front edge of the rear portion 3C of the door sash portion 3 are formed in an arc shape parallel to each other. The glass run 5b by extrusion molding can be used in the portion between the molded glass runs 5a at the upper and lower corners of the rear side portion 3C.

Therefore, the front side 3 of the door sash 3
Since the extruded glass run 5a can be used for the rear part 3C together with the upper part 3B, the cost can be reduced as compared with the case where the glass run 5b formed by molding is used for the entire rear part 3C of the door sash 3. Can be.

Further, since the glass run 5a having a constant cross-sectional shape by extrusion molding can be used for the rear side portion 3C of the door sash portion 3, the width dimension Y of the rear side portion 3C of the door sash portion 3 can be reduced, and the appearance is improved. Can be improved, and the degree of freedom in modeling increases.

A door glass G formed in an arc shape
Is a trailing edge line P at the rearmost end of the door glass G.
Since the door glass G is disposed so as to be in contact with the door glass G at a substantially middle position in the vertical direction of the door glass G, the door glass G can secure a sufficient wrap margin with respect to the glass run 5a when fully closed. Even when the glass G is half-opened, the door glass G can secure a sufficient wrap margin for the glass runs 5a and 5b in the lower half of the rear side 3C of the door sash 3.

Therefore, the door glass G does not rattle at the rear side 3C of the door sash portion 3 whether the door glass G is fully closed or half-open.

When the door glass G moves up and down, the upper end of the rear edge GB is immediately separated from the glass run 5b, and the door glass G is pointed to the glass run 5 at the rear side 3C of the door sash 3. Since it slides in a contact state, sticking with the glass run 5 is eliminated, and smooth lifting and lowering is possible.

[0026]

[0027]

As described above, according to the present invention, an extruded glass run can be used on the rear side of the door sash corresponding to the rear edge of the door glass. Can be reduced in cost as compared with the case of using, and the width dimension of the rear side portion of the door sash can be reduced, so that the appearance can be improved.

The door glass is not only fully closed,
Even when the door sash is half-open, a sufficient wrap margin can be secured to the lower half of the rear side of the door sash, so that the door glass can be prevented from fluttering.
