BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure for a sash bar in an automobile door used for partitioning an elevator window and a grated window.

[0002]

2. Description of the Related Art A rear door 1 used in a sedan type four-door passenger vehicle (vehicle) as shown in FIG. The lower part of the overhanging part is occupied by the hall house 4.

Therefore, the rear door 1 having the window frame 5 is
As shown in FIG. 13, a sash bar 7 that extends from the upper side of the window frame 5 toward the inside of the door panel 6 is provided on the rear side of the window frame 5 so that the window frame 5 can be stored with the lifting window 8. It is divided into other parts.

The sash bar 7 is usually a metal sash member (shown in FIG. 15) having a substantially H-shaped cross section in which the intermediate wall 7a faces the inside / outside of the vehicle compartment. On the front side of the divided window frame 5, a lifting window 8 is driven up and down by a regulator (not shown).
Is provided. Further, a fitting window 10 is provided on the rear side of the remaining window frame 5 which has a triangular shape.

In such a sash bar 7, after the grated window 10 is mounted in the window frame 5, the upper end is joined to the inner surface of the window frame 5 by screwing, and the lower end side is referenced to the same position as the door panel 6 It is fixed to.

Conventionally, in the rear door 1 having such a sash bar 7, in order to prevent water and the like from entering from the end of the sash bar, a seal protector 11 is used as disclosed in Japanese Utility Model Publication No. 57-5211. Sealing is performed between the joints between the window frame 5 and the sash bar 7.

Specifically, a seal protector 11 as shown in FIGS. 14 to 16 has been adopted. Before describing the seal protector 11, the joining structure of the upper end of the sash bar 7 that has been conventionally used will be described. The upper end of the sash bar 7 extends over the side walls 7b and 7c located outside the vehicle interior. From the intermediate wall 7a, for example, a bracket 12 formed by bending a strip plate into an L shape along the upper side of the window frame is projected. A screw hole 13 is formed in the plate surface portion of the bracket 12 on the front end side.

A through hole 14 is previously formed at a predetermined position on the bottom wall 5a of the window frame 5 having a groove shape. The seal protector 11 has a substantially U-shaped cross section, and has a connecting member 16 that is elastically displaceable in a direction in which the interval is narrow, and spacers 17 and 18 formed at both ends of the connecting member 16. I am doing it.

In the seal protector 11 as described above, after the fitting window 10 is mounted on the window frame 5, the entire seal protector is placed inside the window frame 5 by utilizing the elastic displacement of the connecting member 16 as shown in FIG. Fit and temporarily fix.

Spacers 17 and 18 are provided between the upper end of the window and the window frame 5.

By the way, in the structure in which the seal protector 11 is temporarily fixed to the window frame 5 and then the upper end of the sash bar 7 is joined, the seal protector 11 is not positioned at the sash bar joining position X of the window frame 5. There is.

When the screws are screwed, the rotational force applied to the sash bar 7 may cause a positional shift between the sash bar 7 and the seal protector 11. Therefore, the seal protector 11 can adjust the seal protector 11 in the front-rear direction as shown in FIG. 16, and in order to prevent displacement, a groove for allowing the screw 15 screwed in the front-rear direction to the intermediate wall 16a. The holes 19 are formed, and further, the protrusions 20 that can contact the vertical walls 12a of the brackets 12 of the sash bar 7 are formed.

According to this, after the seal protector 11 is temporarily fixed, the upper end of the sash bar 7 is temporarily fixed to the sash bar joining position X of the window frame 5 with the screw 15 as shown in FIG. As shown in FIG. 17 (b), the seal protector 11 is slid until the protrusion 20 abuts on the intermediate wall 7 a of the sash bar 7 to position the seal protector 11 at the front-rear position and prevent the screw 15 from rotating. When the sash bar 7 is fixed to the window frame 5 with the spacers 17 and 18, the spacers 17 and 18 are interposed between the joints at a predetermined position without displacement.

[0014]

However, with such a seal protector 11, the work of joining the sash bar 7 to the window frame 5 is the work of temporarily fixing the seal protector 11 (the work of setting the seal protector 11) and the sash. In addition to the work of screwing the bar 7 to the window frame 5, the seal protector 11 is separately aligned (rotation stop).
The work of joining the sash bar 7 is troublesome.

The present invention has been made in view of the above circumstances, and its object is to provide a seal protector,
An object of the present invention is to provide a joint structure for a sash bar in an automobile door that can be simply and without being displaced and can be interposed between a window frame and a sash.

The sash bar 7 also has a structure having an H-shaped cross section as shown in FIG. 8 and having an L-shaped bracket 12 on the intermediate wall 7a, as described in the section "Prior Art". However, a structure is used in which the upper end of the sash bar 7 is obliquely cut out so as to match the side wall shape of the window frame 5.

The structure of the seal protector 11 will be described. Reference numeral 30 in FIG. 3 denotes a base portion which is a main body of the seal protector 11. The base portion 30 is composed of, for example, a strip plate made of synthetic resin and extending in the vertical direction.

As shown in FIG. 7, the upper end of the base portion 30 is obliquely cut out according to the upper end shape of the sash bar 7. A pair of substantially parallel spacers 32a and 32b are provided so as to project at both sides of the upper end portion in the height direction and in the width direction at a right angle to the longitudinal direction of the base portion 30. In addition, the spacers 32a, 32
b is also made of a synthetic resin member similar to the base portion 30.

Further, from the lower part of each spacer 32a, 32b, a rib piece 3 having an L-shaped cross section which is continuous with the side edge of the base portion 30.
3a and 33b extend so that the rigidity of the base portion directly below the spacer is made higher than that of the other portions.

Further, a pair of rib-shaped claws 34a, 34b which closely face and face the portions where the wall portions of the rib pieces 33a, 33b intersect are projected from the lower portions of the spacers 32a, 32b.

The seal protector 11 has these claws 3
4a and 34b are used to assemble the upper end of the sash bar 7 as shown in FIG. That is, the nail body 34
The gap between a and 34b and the base portion 30 is set to a gap amount according to the thickness dimension of the intermediate wall 7a of the sash bar 7.

The spacers 32a and 32b are positioned at points corresponding to the side wall positions of the sash bar 7. As a result, if the base portion 30 is inserted along the wall surface of the intermediate wall 7a from the upper end of the sash bar 7 until the spacers 32a, 32b and the side walls 7b, 7c contact each other, the base portion 30 and the claws 34a, 34b. And are arranged on both sides of the intermediate wall 7. That is, the intermediate wall 7 is sandwiched between the base portion 30 and the claws 34a and 34b, and the seal protector 11 is assembled to the sash bar 7.

Of course, the base 30 and the claws 34a, 3
4b is arranged at a position where it does not interfere with the bracket 12 of the sash bar 7. In addition, the base portion 30 is the intermediate wall 7a.
, And the claws 34a and 34b are arranged at both ends of the intermediate wall 7 in the vehicle interior and exterior directions, and a high mounting strength can be obtained by utilizing the clamping.

The spacers 32a and 32b are set to have lengths corresponding to the widths of the side walls 7b and 7c, respectively. 4 to 7 are provided below the spacers 32a and 32b.
As shown in FIG. 5, when the seal protector 11 is attached to the end of the sash bar, the groove portions 35a and 35b that fit with the end of the side wall of the sash bar 7 are formed.

A receiving portion 36a for receiving the side wall 5b of the window frame 5 is formed above the spacer 32a. Further, on the upper portion of the spacer 32b, a groove portion 36b capable of fitting with the side wall end of the window frame 5 is formed.

The receiving portion 36a and the groove portion 36b are provided with the seal protector 11 assembled at the end of the sash bar to the window frame 5.
It is set so as to be combined with the side wall end of the window frame 5 as it is placed at the sash bar joining position X.

Of the spacers 32a and 32b, at least the upper portion of the spacer 32b arranged outside the window frame 5 has an abutting portion 38 protruding toward the inside of the window frame 5 as shown in FIGS. Are formed.

The abutting portion 38 is formed, for example, by extending an inner wall portion 37b constituting the groove portion 36b upward (to the window frame 5 side). The shape of the abutting portion 38 is the shape of the seal protector 11.
The side wall 5c as the sash bar is placed at the sash bar joining position X.
Is formed so as to be arranged along the inner surface of the.

The structure in which the seal protector 11 is restrained by utilizing the fact that the abutting portion 38 strikes the side wall 5c of the window frame 5 is used. Using this structure, the seal protector 11 uses the screw 15 to secure the window frame 5 and the bracket 12 to each other.
When is fastened, the spacers 32a and 32b are interposed between the joints (inside and outside) of the window frame 5 and the ends of the sash bar.

That is, when mounting the sash bar 7 on the window frame 5, first, the seal protector 11 shown in FIGS. 4 to 7 is set on the upper end of the sash bar 7 as shown in FIG.

This is carried out by inserting the base portion 30 and the claw portions 34a, 34b so as to sandwich the intermediate wall 7 of the sash bar 7 from both sides from the upper end of the sash bar 7 as shown in FIG. .

Specifically, when the spacers 32a and 32b are inserted until they come into contact with the side wall ends of the sash bar 7, as shown in FIG.
As shown in FIG. 10, the intermediate wall 7 of the sash bar 7 is sandwiched between the base portion 30 and the claw portions 34a and 34b.

As a result, the entire seal protector is sandwiched between the ends of the sash bar. At this time, the spacers 32a,
Side walls 7b and 7c of the sash bar 7 are fitted and inserted into the respective groove portions 35a and 35b of 32b.

When the assembly of the seal protector 11 is completed, the sash bar end is then, together with the seal protector 11, as shown by the arrow in FIG. 1, the window in which the fitting window 10 has been installed. 1 is inserted into the upper side of the frame 5 at the sash bar joining position X,

Here, the receiving portion 3 of the spacers 32a and 32b
6a and the groove 36b are provided in advance on the side walls 5b and 5 of the window frame 5, respectively.
Since the shape is set according to c, the side wall end is received according to the positioning of the bracket 12. Of course, since the abutting portion 38 of the spacer 18 is also shaped to follow the inner surface of the side wall 5c, it overlaps with the inner surface of the side wall 5a according to the positioning of the bracket 12.

After that, when the screw 15 is screwed from the through hole 14 of the window frame 5 into the screw hole 13 of the overlapping bracket 12, the upper end of the sash bar 7 is located at the upper side of the window frame 5 as shown in FIG. Is fixed to each spacer 32a,
32a is interposed between the joints (inside and outside) of the upper side of the window frame 5 and the ends of the sash bar to seal the two.

At this time, the seal protector 11 is different from the sash bar 7 in the base portion 30 and the claw portions 34a, 34b.
The movement is restricted by being clamped to the intermediate wall 7a. Further, since the movement of the sash bar 7 is restricted by the abutting portion 38 extending from the spacer 32b to the inner surface of the window frame 5, the sash bar 7 is displaced even if it receives a rotational force due to screwing. There is no need to worry.

Therefore, the seal protector 11 is
The base portion 30 is sandwiched between the sash bar end and the intermediate wall 7a.
Insert the claws 34a, 34b and the claws 34a, 34b, and set them together with the sash bar end on the window frame 5 and screw them together.
Separately, the spacers 32a, 32a can be mounted by the assembling work of the sash bar 7 that does not require the work of adjusting the front-rear position and the rotation stop.
Can be interposed between the joints (inside and outside) between the window frame 5 and the ends of the sash bar.

As a result, the spacers 32a, 32a can be simply interposed between the joints between the window frame 5 and the sash bar end without causing unnecessary positional displacement. In particular, in the structure in which the base portion 30 overlaps most of the intermediate wall 7a, and the claws 34a and 34b are arranged at both ends of the intermediate wall 7b in the vehicle interior and exterior direction, high mounting strength is provided, and the seal protector 11 is provided. Since it has a high restraint performance against the sash bar 7, it exhibits an excellent effect as a countermeasure against the positional deviation.

Moreover, when the abutting portion 38 is provided on the spacer 18 outside the window frame 5, not only the movement of the seal protector 11 can be restricted, but also a high sealing performance with respect to the outside of the vehicle can be secured.

In the embodiment, the abutting portion 38 is provided on the spacer 32b arranged outside the window frame 5, but both spacers, that is, the spacer 32a arranged inside the window frame 5, also collide. This section (not shown) may be provided.
