Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle door sash structure, and more particularly to an improvement in a vehicle door sash structure in which an upper sash and a lower sash are connected.

Generally, as shown in door sash 8#i, FIGS. 1 and 2m, a window frame is molded on the upper part of the door body 1, and the door body 1
It extends downward at the front and back of the interior. For this reason, if the door sash 8 were to be integrally formed and assembled onto the door body 1 in advance, it would be extremely troublesome to install the door lock device 3 etc. disposed between the door sash S and the door body 1. Become. Therefore, conventionally,
The door sash S is divided into an upper sash 4 that molds a window frame that is fixed in advance to the door body 1, and lower sashes: LS and S that can be connected to both lower ends of the upper sash 40.
The above lower sash s, sI/i, "'door lock device 3
After completing the installation, the door body 1 can be installed.

By the way, when attaching the sealing weather strip 6 around the door to the periphery of the vehicle interior side of the FA main body 10, the third
As shown in the figure, since a mounting recess 7 is formed as a mounting surface for the weather strip 6 on the periphery of the door inner panel 1a constituting the door body 1 on the inside of the vehicle, the weather strip 6 is attached to the door inner panel. It is arranged at a position offset by a dimension d from the peripheral edge-crotch portion 8 of the panel 1a. In order to improve the sealing performance around the door, it is necessary to smoothly connect the weather strip 6 from the periphery of the upper sash 40 to the periphery of the door body 10. The position is along the mounting surface of the weather strip 6 of the door body 1, and the lower portions of both ends of the upper sash 4 are arranged at positions offset from the peripheral edge-crotch portion 8 of the door inner panel 1a. For this reason,
The upper sash 4 is attached to the periphery of the door inner panel 1a.
The upper sash 4 cannot be directly fixed to the back surface of the crotch section 8, and is fixed to the door body 1 via a holding bracket 9 provided on the periphery of the door impeller 1a and the back surface of the crotch section 8.

Further, as shown in FIGS. 4 and 5, a mail member M is fixed to the upper part of the lower sash 5. It is equipped with 10. On the other hand, there is a female member at the bottom of the upper trunk 4! is fixed, and the female member P forms a thank-you female part 11 between the female member P and the upper sash 4 into which the mail part 10 fits. The upper end of the lower sash 5 is
When the male part 10 is fitted into the female part 11,
The upper sash 40 is positioned and connected to the lower end of the sash 40. Further, the lower part of the lower sash 5 is screwed and fixed to the door body 1 via a one-channel bracket 12, as shown in FIGS. 1 and 4. In addition, in FIGS. 2 to 4, 1b is a door outer panel, and 13 is a glass run.

However, in such a conventional door sash structure, a holding bracket 9 is required to fix the upper sash 4 to the door body 1, and the upper sash 4K
Since the mail member M and the female member F are required to connect the O-assembly 5, the number of parts not only increases accordingly, but also requires the upper sash 4 to be attached to the retaining bracket 9 and the male member M or the female member F. However, in recent vehicles where the waistline of the door has been lowered to ensure side visibility, the height of the door body 1 has become relatively low. Moreover, since the lower end of the upper sash 4 must be placed above the door look device 3, etc., it is difficult to secure a mounting space for the two members in the upper sash 4.

The present invention has been made based on the above-mentioned viewpoints, and its object is to attach it to an upper sash among a male member and a female member. To provide a door sash structure for a vehicle, which allows an upper sash and a lower sash to be reliably connected while omitting one of the members, thereby reducing the number of parts and effectively securing mounting space for members in the upper sash. It's about doing.

The gist of the present invention is a vehicle door sash structure in which an upper sash and a lower sash are connected by forming a male portion or a female portion on a holding bracket that holds a rear sash.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the embodiment shown in FIGS. 6 and 7, a holding bracket 9 is fixed by welding or the like to the lower part of the upper sash 4 constituting one side of the door sash S, and the lower end of this holding bracket 9 is connected to the lower end of the upper sash 4. arranged to match.

In this embodiment, a mail member M having a mail part 10 projecting upward from the upper end of the lower sash 5 is fixed by welding or the like to the upper part of the lower sash 5 constituting the other side of the door sash 8. However, unlike the conventional case, there is a retaining bracket 9 on the upper satush 4 side.
A hole is formed between the L brim sash 4 and the F
The female part 11 is fitted with the female part 10. Incidentally, a bracket 12 as shown in FIGS. 1 and 4 is provided at the lower part of the lower sash 5.

Therefore, in the door sash structure according to this embodiment,
The upper sash 4 is fixed to the door body 1 via the holding bracket 9, and the upper sash 4 and the lower sash 5 fit the female part 11 of the lower sash 5 into the female part 11 between the upper sash 4 and the holding bracket S. As a result, the lower end of the upper sash 4 and the upper end of the lower sash 5 are brought into contact and positioned and fixed. At this time, the upper satush 4 has a conventional female member F.
is not attached, so that the molding process and assembly process of the female member r can be omitted. Furthermore, as for the mounting space for the parts in the wing seat 4, it is sufficient to secure only the space corresponding to the holding bracket 9, and even if the space between the waist line of the door and the door lock device 311 is narrow, the range of this space is sufficient. Since the mounting space for the members in the upper sash 4 is within the range that can be sufficiently accommodated, the upper sash 4 is
It is reliably placed in a position ψ that does not interfere with the door lock device 3 or the like.

In the above embodiment, the lower sash 5IICFi
Although the mail member M is installed, as shown in Fig. 8,
The mail part 10 may be formed on the lower sash 5 itself, and the mail member M may also be eliminated. Further, in the above embodiment, the female portion 11 is formed on the holding bracket 9, but the present invention is not limited to this, and as shown in FIG. 10 t and at the same time, a female member F having a female portion 11 may be attached to the lower sash 5° side. Further, in the above embodiment, the lower end of the holding bracket 9 is made to coincide with the lower end of the upper sash 4, but it is not necessarily necessary to make them coincide. Furthermore, Mail City, Female I! The specific shape of 1611 is not necessarily limited to that shown in the examples,
It doesn't matter what shape it is, as long as it can be used in a similar way.

As described above, according to the vehicle door sash structure according to the present invention, a male part or a female part is formed on the holding bracket that fixes the upper sash to the door body, and the upper sash and the lower sash are joined together. This eliminates the need to attach a male member or a female member to the upper sash side9, thereby reducing the number of parts, reducing costs, and reducing the weight of the vehicle. Also, since it is only necessary to attach the retaining bracket to the upper satush,
Compared to the past, the mounting space for the members in the rear sash can be narrowed, and there is no risk that the upper sash will interfere with a door lock device or the like when the upper sash is disposed.
