Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damper stay mounting structure for a flip-up type back door glass, and more particularly, to an improvement in a mounting structure for facilitating replacement of a back door glass and a damper stay.

[0002]

2. Description of the Related Art In a vehicle with a back door or the like, a glass W of a back door D can be flipped up and opened as shown in FIG. There is. In this case, the back door glass W
In order to openly support the door, a gas filled damper stay 1 is often provided between the left and right positions of the glass and the back door panel as shown.

[0003] The connecting portion between the tip of the rod 11 of the damper stay 1 and the back door glass W has a conventional structure as shown in FIG. That is, in FIG. 8, a cylindrical collar 21 is inserted into a mounting hole W1 provided in the back door glass W from the back surface (the lower surface in the figure).
Inside, a retainer 3 constituting a connecting member is inserted from the glass surface side via a seal ring 22. The retainer 3 includes a circular head portion 31 pressed against the seal ring 22 and a cylindrical portion 32 extending from the center of the circular head portion 31 into the collar 21, and is connected to a screw portion 33 formed on the inner periphery of the cylindrical portion 32. Are screwed. On the other hand, a ball joint 5 constituting a connecting member is fixed to the tip of the rod 11 of the damper stay 1, and a recess 51 formed in a hemispherical portion at the tip of the ball joint 5 fits into the spherical head 41 of the pivot bolt 4. Thus, the two are connected so that the angle can be freely changed.

[0004]

When the back door glass W and the damper stay 1 are replaced in the above-mentioned conventional damper stay mounting structure, the pivot bolt 4 is mounted with the head 31 of the retainer 3 fixed with pliers or the like. Rotate to remove. However, the retainer head 31 exposed to the outside of the vehicle has a smooth shape with no surface irregularities from the viewpoint of appearance, and it is difficult to remove it because it is slippery to fix it with pliers or the like, so it takes time to remove it, Alternatively, at this time, there is a problem that the retainer head 31 is damaged.

Accordingly, the present invention has been made to solve such a problem, and it is possible to easily replace a back door glass or a damper stay without damaging a connecting member provided on the back door glass or requiring labor for work. It is an object of the present invention to provide a damper stay mounting structure for a flip-up type back door glass that can be flipped up and down.

[0006]

In order to achieve the above object, according to the present invention, there is provided a back door which is rotatably connected to an upper edge of an opening of a back door (D) so as to be opened upward and openable. A glass (W), a damper stay (1) provided between the back door glass (W) and the panel of the back door (D) and supporting the open back door glass (W); and A joint member (6) for detachably connecting one end of the damper stay (1) to a connecting member (3, 4, 5) provided on the back door glass (W).

In the present invention, one end of the damper stay is separably connected to the connecting member of the back door glass by a joint member. Therefore, when the back door glass and the damper stay are replaced, the connecting member is damaged or a large amount of work is required. The back door glass and the damper stay can be easily replaced by separating the joint member without the need for troublesome work.

[0008] The reference numerals in parentheses indicate the correspondence with specific means described in the embodiments described later.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a connecting structure between a tip end of a rod 11 of a damper stay 1 and a back door glass 2, and this drawing corresponds to an enlarged view of a portion A in FIG. In FIG. 1, a cylindrical collar 21 is inserted into a mounting hole W1 provided in the back door glass W from the back surface (the lower surface in the figure), and a seal ring 22 is inserted into the collar 21 from the glass front surface. The retainer 3 constituting the connecting member is inserted through the intermediary. The retainer 3 includes a circular head portion 31 pressed against the seal ring 22 and a cylindrical portion 32 extending from the center of the circular head portion 31 into the collar 21, and is connected to a screw portion 33 formed on the inner periphery of the cylindrical portion 32. Are screwed. On the other hand, a ball joint 5 constituting a connecting member is connected to a distal end of the rod 11 of the damper stay 1 via a joint member 6 described in detail later, and a concave portion 5 formed in a hemispherical portion of the distal end of the ball joint 5 is formed.
1 is fitted to the spherical head 41 of the pivot bolt 4, and both are connected so that the angle can be changed.

FIG. 2 shows the detailed structure of the joint member 6. In FIG. 2, the joint member 6 is a damper stay 1
Has a cylindrical housing 61 fixed to the tip of the rod 11, and openings 611 are formed at a plurality of locations on the peripheral wall thereof.
The ball 62 is located in each opening 611. A slidable return ring 63 is fitted around the outer periphery of the housing 61, and a front end (right end in FIG. 2) 6 of the return ring 63.
31 protrudes into the opening 611. Return ring 6
3 is urged rightward in FIG. 2 by a coil spring 64. A tubular knob 65 is located adjacent to the return ring 63. The shaft portion 52 of the ball joint 5 inserted into the housing 61 is formed with concave portions 521 having an arc-shaped cross section at a plurality of positions on the outer circumference. Omission is regulated.

In the joint member 6 having such a structure, the knob 65 is integrally formed with the return ring 63 by the coil spring 6.
When the knob 65 is moved in the direction of the arrow in FIG. 2 against the spring force of FIG. 4, the notch 651 at the opening edge of the knob 65 reaches just above each ball 62 as shown in FIG. As a result, the shaft portion 52 of the ball joint 5 can be pulled out of the housing 61 as shown in FIGS. Therefore, when the back door glass W and the damper stay 1 are to be replaced, the knob 65 of the joint member 6 is operated to change the state from FIG.
By extracting the shaft portion 52 of the ball joint 5 from the housing 61 of the joint member 6 as shown in FIG.
By separating the ball joint 5 and the damper stay 1, the back door glass W and the damper stay 1 can be easily replaced. Thus, it is not necessary to separate the retainer and the ball joint using pliers or the like as in the related art, so that the retainer is not damaged and the separating operation is easy.

When the back door glass W after replacement and the damper stay 1 are to be joined again, the shaft of the ball joint 5 is inserted into the housing 61 of the joint member 6 shown in FIG. When the insertion of the portion 52 is started, the ball 62 contacts the front end 631 of the return ring, the return ring 63 is moved to the left in FIG. 5 against the spring force of the coil spring 64, and the ball 62 is It moves radially outward so as not to interfere with 52. When the shaft portion 52 of the ball joint 5 is largely inserted into the housing 61, the ball 62 is radially outwardly recessed by the return ring 63 urged by the coil spring 64.
2 and the pivot bolt 62 is prevented from coming out of the joint member 6 as shown in FIG.

[0013]

As described above, according to the damper stay mounting structure of the flip-up type back door glass of the present invention, the back door glass and the dam past stay can be easily formed without damaging the connecting member or requiring labor for work. Can be exchanged.
