Description

[Detailed Description of the Invention] The present invention relates to an improvement in a door sash for a vehicle that opens and closes around a hinge.

Doors that rotate around the hinge of a vehicle such as an automobile, and have a shelf protruding from the back of the sash along the length of the sash, are
The surface width of the sash, the gap between the shelf tip, the body, and the sealing surface width of the doorstop are all related to each other, and these dimension settings are determined by the appearance of the car body, sealing effect, and door opening/closing. Affects functionality, etc. This effect is particularly noticeable on the sash located at the free end of the door.

Conventionally, the shelf protruding from the back side of this type of sash has been provided perpendicularly to the front surface of the sash, which has caused various inconveniences. This is explained in Figures 2 to 4.
The diagram will be explained. Figures 2 to 4 are cross-sectional views corresponding to the cross section taken along the line M-M in Figure 1;
The figure is a perspective view showing a main part of the outer surface of the left door of a passenger car.

In Figure 1, 1 is the body, 2 is the front door,
3 is the rear door, 4 is the front door sash, 5 is the rear door sash, 6 is the center line of the front door hinge, 7 is the center line of the rear door, and 8 and 9 are the respective window glasses. Further, F indicates the front part of the body, and T indicates the rear part of the body.

As shown in Figures 2 to 4, the sash surface 1
A shelf 11 is provided on the back side of the width center part of the window 10, and is substantially perpendicular to the surface 10, and a bent part is provided behind the shelf 11 to form a sliding guide part 12 for the window glass. Holding portions 13 of weather strips 14 are formed on the back surfaces of the weather strips 14, respectively.

In this way, the conventional sash cross-sectional shape has a shelf extending from the center of the back surface of the sash that projects almost perpendicularly to the sash surface. , 3 and 4 will be explained in order.

In Fig. 2, if we try to keep the sealing surface width b of the door stop at a constant value and the sash surface width c to a constant width, the gap a (opening) between the body 1 (pillar) and the sash end surface gap)
Since the opening gap must be set wide, the appearance is not good, and if the opening gap is narrowed, the weather strip 14 enters while strongly contacting the body. Note that E indicates the direction of entry of the weather strip attached to the sash.

In Fig. 3, if the sash surface width c is limited to a constant width and the gap a between the body 1 and the sash end surface is to be kept narrower, the seal surface width b of the doorstop will inevitably become narrower. Therefore, the watertightness of this part is insufficient.

In Fig. 4, if you try to keep the gap a between the body 1 and the end face of the sash within the required constant width while ensuring a sufficient amount of the sealing surface b of the door stop, the sash surface width c will be increased. There must be. This wide surface width causes an unsightly appearance.

The present invention has been made in order to eliminate the design defects of the conventional sashes as described above. The present invention will be explained below with reference to FIG.

FIG. 5 is a sectional view corresponding to the cross section taken along the line M-M in FIG. 1, where 1 is the body, 4 is the sash, and 10
11 is a sash surface, 11 is a shelf, 12 is a window glass sliding guide, and 14 is a weather strip.

In the drawings, O is the center point of the door hinge, S is the rotation locus of the free end of the door (in this embodiment, specifically the end of the weather strip 14) when the door is closed, and E is the center point of the door hinge. indicate the direction in which the weather strip enters when the door is closed.

Now, in the present invention, in order to solve the problem of the sash on the free end side of the door of the conventional one, the protruding direction of the shelf part 11 with respect to the sash surface 10 is tilted toward the door hinge side instead of perpendicular to the conventional one. It was formed. The free end of the door (hereinafter referred to as the weather strip end)
The rotation locus S naturally forms an arc, but an arc in an extremely small section of the rotation locus S with a large rotation radius is close to a straight line and can be considered to have directionality. S shown in the figure
is the realization of the above straight line. Therefore, the protruding direction of the shelf is set to substantially follow the direction indicated by the linear approximation arc of an extremely small section of the trajectory S at the portion closest to the shelf.

According to the above, the dimensions of the gap e between the tip of the shelf 11 and the body 1, the gap a (opening gap) between the body 1 and the end face of the sash, the sash surface width c, and the seal surface width b are set to appropriate dimensions. can be formed into

That is, since the opening gap a can be set to the minimum size without sacrificing the sealing surface b, the appearance can be improved. Further, since the effective dimension of the seal surface width b can be obtained without enlarging the sash surface width c, and the contact surface of the weather strip can be set to the same level as a normal good one, one of the causes of seal failure is eliminated. Furthermore, the above-mentioned slope of the shelf causes the end of the weather strip attached to the shelf to retreat to the left (toward the center of the door) as seen in the figure.
A sufficient sealing surface width b can be obtained without increasing the sash surface width c while maintaining a narrow opening gap a with good appearance. In other words, a narrower sash surface width can be obtained, making it possible to improve the design.

As described above, the present invention successfully solves the above-mentioned disadvantages of the conventional ones.
Although the above description has been made regarding the front door sash of two doors, it goes without saying that the technology of the present invention can also be applied to the rear door sash.
