[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener used for attaching an adhesive window glass of an automobile to a mounting surface provided around a window opening.

[0002]

2. Description of the Related Art As described above, for example, Japanese Unexamined Utility Model Publication No. 4-90417 discloses a fastener as described above, which is inserted into a mounting hole formed in a mounting surface provided around a window opening. And a glass support for supporting the outer edge of the window glass, which is integrally formed of synthetic resin.

[0003]

However, since the body of an automobile is assembled by welding an iron plate having a complicated shape, the size of the window opening, specifically, the size from the reference position below the glass fixing to the upper edge of the opening is determined. There are variations for each vehicle body.
In addition, there are manufacturing variations in the vertical dimensions of the window glass. For this reason, when attaching the window glass with the above-mentioned conventional fastener, for example, when attaching the window glass whose vertical dimension is the minimum dimension within the tolerance to the vehicle body whose window opening dimension is the maximum dimension within the tolerance, The gap between the upper end and the car body becomes large over the entire length,
Alternatively, the gap width differs between left and right. Therefore, if the allowable range of the gap is not set to a large value, the defective product occurrence rate will increase. On the other hand, if the allowable range is set to a large value, it must be designed so that a molding covering the gap can be used in a wide range. If the width of the gap is not constant, the work of assembling the mall or the like becomes difficult. Therefore, the present invention can suppress the difference in the gap above the window glass by making it possible to select the position for supporting the lower end of the window glass even if the above-mentioned variation exists, and can also keep the width of the gap constant. It is intended to provide a window glass fastener.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above-mentioned object, and is intended to be inserted into a mounting hole formed in a mounting surface provided on a periphery of a window opening of a vehicle body. An engagement leg engaged with the mounting surface; a glass support formed integrally with the engagement leg and forming a glass abutment surface capable of abutting the vehicle body abutment surface and the outer edge of the window glass in contact with the attachment surface; The base end is connected to the glass supporting portion, extends outside the glass contact surface, and bends into a first state extending off the glass contact surface unless bent at a bent portion formed in the middle. And a spacer piece that can be converted into the second state facing the glass contact surface.

[0005]

In the first state in which the spacer piece extends off the glass contact surface, the lower end of the window glass can be placed directly on the glass contact surface. On the other hand, when the spacer piece is bent at the bent portion and converted to the second state facing the glass contact surface, the window glass is interposed between the lower end of the window glass and the glass contact surface with the spacer piece interposed therebetween. This is the same as holding the window glass at a relatively high mounting position. Therefore, if the gap at the upper end of the window glass becomes large when the window glass is placed directly on the glass contact surface, the gap can be reduced by interposing the spacer pieces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The fastener 1 in the embodiment holds a window glass 3 fixed to an attachment surface 2 provided on a peripheral edge of a front window opening of an automobile with an adhesive. The fastener 1 basically has a relatively high height such as nylon or polyacetal formed by an engaging leg 5 inserted into a mounting hole 4 formed in the mounting surface 2 and a glass support 6 supporting the window glass 3. A resin layer 7 made of a soft synthetic resin is formed integrally with a vehicle body abutting surface in contact with the mounting surface 2 of the vehicle body.

The glass supporting portion 6 has a wall 9 erected on a part of one side edge of the plate-like base 8, the outer surface of the wall 9 is used as a glass contact surface 10, and the engaging leg 5 projects. The set surface is the body contact surface 1
It is set to 1. A base end of a spacer piece 12 extending outside the glass contact surface 10 is connected to the glass supporting portion 6 beside the wall 9.

The spacer piece 12 shown in the drawing is a long elastic plate formed integrally with the glass support 6 on substantially the same plane as the base 8, and its width direction is substantially orthogonal to the glass contact surface 10. The first bent groove 1 is provided on the surface near the engagement leg 5 near the base end.
3a is formed in the width direction, and a second bent groove 13b is formed in the width direction substantially at the center from the first bent groove 13a to the front end on the opposite surface.

The spacer piece 12 having such a configuration
If the first bending groove 13a and the second bending groove 13b do not bend, the entire length of the first bending groove 13a and the second bending groove 13b extends substantially on the same plane as the base 8 as shown by the solid line in FIG. 1
When the state is maintained and the first bent groove 13a and the second bent groove 13b bend, as shown by the dotted line in FIG. 4A, the second bent part facing the glass contact surface 10 as shown by the dotted line in FIG. Convert to state.

The engaging leg portion 5 extends from the glass supporting portion 6 substantially perpendicularly to a hollow substantially quadrangular prism which gradually narrows toward the tip thereof, and has a substantially triangular elastic locking piece 1 on the opposite side surface.
4 and a slit 16 is formed in the inner peripheral surface of the hollow portion 15. A predetermined gap is formed between the upper end of the elastic locking piece 14 and the vehicle body contact surface 11. Therefore, when the engaging leg 5 is inserted into the mounting hole 4 formed in the mounting surface 2 and is sufficiently pushed until the resin layer 7 of the vehicle body contact surface 11 comes into contact with the mounting surface 2, the elasticity passing through the mounting hole 4 is obtained. Locking piece 1
4 returns to the outside by elasticity, whereby the elastic locking piece 1
The upper end of 4 is engaged with the opening edge of the mounting hole 4 to be in a temporary fixing state. Then, a tapping screw 17 is provided in the hollow portion 15.
When the screw is screwed in, the side surface of the engaging leg 5 is widened, and the upper end of the elastic locking piece 14 is securely locked to the opening edge of the mounting hole 4, which is combined with the widening of the engaging leg 5 in the mounting hole 4. Therefore, the fastener 1 is firmly fixed to the vehicle body.

When the window glass 3 is held by the fastener 1 having the above-described configuration, the window glass 3 is mounted in a state where the vertical length of the window glass 3 is relatively short and the window glass 3 is placed on the glass contact surface 10 as it is. In the case where the gap D at the upper end of the window glass 3 becomes large, as shown in FIGS. 1 and 6, the spacer piece 12 is bent in a V-shape and positioned on the glass contact surface 10. The lower end of the window glass 3 is placed on the V-shaped spacer piece 12. That is,
As shown in FIG. 2, the U-shaped spacer piece 12 is mounted between the glass contact surface 10 and the lower end of the window glass 3. When the window glass 3 is placed on the spacer piece 12 in this manner, the mounting position of the window glass 3 is increased by the width of the spacer piece 12, and the gap D at the upper end of the window glass 3 is reduced.

Since the spacer pieces 12 receive the weight of the window glass 3 in the width direction, and are bent in a U-shape to be dispersed and received at two locations, the spacer pieces 12 are not crushed by the weight of the window glass 3. Absent. Since the spacer pieces 12 are made of elastic plastic, they do not break even when bent, and do not damage the lower end of the window glass 3 even when the vehicle body vibrates.

On the other hand, when the vertical length of the window glass 3 is relatively long, the gap D at the upper end of the window glass 3 can be set even when the window glass 3 is mounted on the glass contact surface 10 with the lower end thereof mounted. Falls within a predetermined range. Therefore,
In such a case, as shown in FIG.
2 is attached with the first state extended without bending. At this time, since the spacer piece 12 extends on substantially the same plane as the base 8 of the glass support portion 6, the spacer piece 12 may hinder the lower end of the window glass 3 from being placed on the glass contact surface 10. Absent.

In the above-described embodiment, the spacer piece 12 is formed integrally with the glass support portion 6. However, the spacer piece 12 is separately formed, and then the base end of the spacer piece 12 is screwed or the like later. 6 may be fixed. In addition, the spacer piece 12 has its base end connected to the glass support portion 6 and extends outside the glass contact surface 10, and comes off from the glass contact surface 10 unless bent at a bent portion formed in the middle. Any configuration is possible as long as it can be converted into a first state that extends and a second state that is bent and faces the glass contact surface 10. For example, the base end is a wall 9 that is a part of the glass support 6.
May be connected. Further, the present invention is not limited to the one bent in the shape of a letter as in the above embodiment.

The glass support portion 6 may have any shape as long as it has a vehicle body contact surface 11 that contacts the mounting surface 2 and a glass contact surface 10 that can contact the outer peripheral edge of the window glass 3. Further, the engaging leg 5 is not limited to the above structure, and may have any configuration as long as it has a function of being inserted into the mounting hole 4 of the mounting surface 2 and engaging with the mounting surface 2. For example, a portion extending substantially perpendicularly from the glass support portion 6 may be bent at an acute angle in the middle and formed into a hook shape with a cross section of a letter shape.

[0016]

As described above, according to the present invention, the window glass is directly placed on the glass contact surface in the first state in which the spacer piece is extended, or the glass piece is bent by bending the spacer piece. By selecting whether the window glass is placed on the glass contact surface with the spacer piece interposed therebetween and converted to the second state facing upward, the size of the window opening and the vertical Even if the dimensions vary, the difference in the gap above the window glass can be kept small. Therefore, no problem occurs even if the above-mentioned variation in dimensions becomes large, and the work of attaching a molding or the like that closes the gap is simplified.
