Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a door glass with a weather strip fixed to the upper end of the door glass and the vehicle body by adjusting a guide rail that guides the vertical movement of the door glass. This invention relates to an adjustment mechanism for a door glass guide rail that adjusts the contact with a door glass guide rail.

(Prior Art) Generally, the door glass of a satsile-less door of an automobile is attached to guide rails installed at the front and rear so that it can be raised and lowered via a link mechanism.The link mechanism can be moved up and down by operating the handle of a regulator. When the door glass is raised and closed, a guide rail is used to adjust the contact between the upper edge of the door glass and the weather strip attached to the window frame of the car body. The upper edge of the door glass is tilted inward by adjusting the mounting part to improve adhesion to prevent wind leakage.

Hereinafter, a conventional door glass guide rail adjustment mechanism will be explained based on FIG. 1.

In the figure, 1 is a door glass, and 2 is a guide rail for guiding a link mechanism (not shown) that raises and lowers the door glass 1 in the vertical direction, and is installed at two locations at the front and rear.

Further, 3 is an outer panel of the door, 4 is an inner panel, 5 is an inner reinforcing plate fixed to the inside of the inner panel 4, and the upper ends of both panels 3 and 4 are provided with the door through which the door glass 1 enters and exits. A glass opening 30 is formed and a weather strip 31 is provided.

A sub-adjustment bolt 6a and a main adjustment bolt 6b are screwed together in the horizontal direction at predetermined upper and lower positions of the inner panel 4, respectively.
a and the main adjustment bolt 6b are screwed into welding nuts 8a, 8b of guide brackets 7a, 7b fixed at predetermined positions on the guide rail 2,
The auxiliary adjustment bolt 6a and the main adjustment bolt 6b are adjusted to move forward or backward to change the inclination of the guide rail 2, so that the upper end of the door glass 1 is brought into close contact with the weather strip 9 on the vehicle body side. There is.

61a and 61b are nuts for fixing the sub adjustment bolt 6a and the main adjustment bolt 6b to the inner reinforcing plate 5, and 62a and 62b are washers.

(Problem to be solved by the invention) However, in the conventional adjustment mechanism described above,
In order to adjust the relationship between the door glass opening 30 and the door glass 1 to be always constant and to ensure that the upper end of the door glass 1 is in a predetermined close contact with the weather strip 9, it is necessary to Since it is a method to adjust and converge the tightening state of two places, the secondary adjustment bolt 6a and the lower main adjustment bolt 6b,
Adjustment work during door assembly was troublesome and required a large amount of labor.

Incidentally, when the tightening is adjusted using only the lower main adjustment bolt 6b, the guide rail 2 rotates around the position of the sub-adjustment bolt 8a (assuming that the structure allows rotation), As a result, the relative position of the door glass 1 and the door glass opening 30 changes in the direction of the vehicle, and the contact distance between the door glass 1 and the weather strip 31 changes, causing a gap between the two, or The elevator may not move up and down smoothly.

In order to prevent such inconvenience from occurring,
In the conventional example described above, the position of the guide rail 2 is adjusted at two points using the upper sub-adjustment bolt 6a so that the relationship between the door glass opening 30 and the door glass 1 is always constant.

Note that when the guide rail 2 is tilted in the left-right direction by adjusting the main adjustment bolt 6a and the sub-adjustment bolt 6b, the mounting surfaces of both the bolts 6a, 6b and the inner reinforcing plate 5 or guide brackets 7a, 7b are straight. Although there may be cases where the angle cannot be maintained, the adjustment difference in the left and right direction is small compared to the vertical relationship between both bolts 6a and 6b, so the rotation angle of the guide rail 2 is also small, and the inner reinforcing plate 5 or guide bracket 7a , 7b during elastic deformation.

(Object of the Invention) The present invention has been made in order to solve the above-mentioned drawbacks of the conventional mechanism. Although the adjustment is done with one bolt, it is possible to maintain a constant relative position between the door glass entrance and exit opening and the door glass, simplifying this adjustment work and enabling smooth upper limit raising and lowering of the door glass. Furthermore, it is an object of the present invention to provide a door glass guide rail adjustment mechanism that is structurally simple.

(Structure of the Invention) That is, the adjustment mechanism according to the present invention for achieving the above-mentioned object is provided such that the door glass can be moved up and down by entering and exiting from the door glass opening formed at the upper end of the door panel, An upper bracket is formed at the upper part and a lower bracket is formed at the lower part, and an upper guide rail bracket and a lower guide are formed at the upper and lower parts of the guide rail for guiding the raising and lowering of the door glass, corresponding to the upper bracket and the lower bracket. A rail bracket is formed, and the lower bracket and the lower guide rail bracket are connected by an adjustment bolt so that the distance between the two brackets can be adjusted, and the adjustment bolt is inclined at an angle α with respect to a direction perpendicular to the vertical direction of the door glass. and an inclined surface is formed on one of the upper bracket and the upper guide rail bracket, and an abutting portion is formed on the other, and the inclined surface has an inclination angle β in the same direction as the angle α and larger than the angle α. and at least one of the inclined surface and the contact portion,
An elongated hole is provided, and the upper bracket and the upper guide rail bracket are connected to each other with the abutting portion abutting on the inclined surface by a fastening bolt inserted through the elongated hole, and the elongated hole is connected to the upper guide rail bracket by the adjustment bolt. When the interval is adjusted and the lower part of the guide rail is moved in the direction of the angle α, the upper part of the guide rail is formed to be movable along the inclined surface, and the inclination angle β is It is characterized in that the door glass is formed so as to swing around the vicinity of the door glass opening as a center of rotation when the distance is adjusted by a bolt.

(Operation of the Invention) Therefore, according to the door glass guide rail adjustment mechanism of the present invention, by rotating the adjustment bolt and changing the position of the lower part of the guide rail, the upper part of the door glass can be adjusted in the direction of the vehicle. You can adjust the contact between the upper edge of the door glass and the weather strip that comes into contact with it.

Its operation will be explained.

If you loosen the fastening bolt at the top of the guide rail and then rotate the adjustment bolt at the bottom of the guide rail to adjust the distance between the lower bracket and the lower guide rail bracket, the bottom of the guide rail will move in the direction in which the adjustment bolt extends. and is displaced vertically and horizontally.

As the guide rail moves up and down, the upper guide rail bracket moves up and down along the long hole of the inclined surface of the upper bracket, and also moves in the left and right directions. In addition, at this time, a relative angular displacement occurs between the fastening bolt of the upper bracket or the upper guide rail bracket, and the rotation angle of the guide rail between the lower bracket or the lower guide rail bracket and the adjustment bolt (the surface contact state collapses).
However, as with the conventional technology, the adjustment difference in the horizontal direction is small compared to the vertical spacing between both bolts, so the rotation angle of the guide rail is small, and the above relative angular displacement is slight, resulting in elastic deformation of the door panel and each bracket. This is absorbed by the internal deflection, so there is no practical problem.

In this way, since the upper guide rail bracket moves along the inclined surface of the upper bracket, the guide rail can change the amount of displacement in the left and right direction between the upper and lower parts, and the inclination angle β of the inclined surface and the adjustment bolt By setting the inclination angle α, it is possible to rotate the guide rail approximately around a point other than the two upper and lower points.

Because of this, even if the distance between the brackets is adjusted using only one lower adjustment bolt, the brackets will not rotate around the position of the upper fastening bolt.

By making the latter angle α smaller than the former angle β, the center of rotation of the guide rail can be positioned above the fastening bolt on the upper part of the guide rail. By appropriately setting the inclination angle of the surface, it can be placed near the door glass opening of the door glass.

When the contact between the upper end of the door glass and the weather strip is adjusted by operating the adjustment bolt, the door glass can be prevented from moving in the left-right direction with respect to the door panel.

After adjusting the contact between the upper edge of the door glass and the weather strip, the tightening bolt is tightened and the adjustment bolt is locked to complete the work.

(Effects of the Invention) As described above, in the present invention, the adjustment work of the fastening bolt at the upper part of the guide rail is no longer necessary, and the position of the door glass and the opening for the door glass can be adjusted by adjusting the one adjustment bolt at the lower part. The contact between the upper end of the door glass and the weather strip can be adjusted while keeping the relationship substantially constant, and the adjustment work can be simplified.

(Example) Examples according to the present invention will be described below in Figures 2 to 6.
This will be explained in detail based on the figures.

In the drawings, the same parts that correspond to the conventional structure are given the same reference numerals and their explanations will be omitted.

First, an upper bracket 10 and a lower bracket 11 are formed at predetermined upper and lower positions on the inside of the inner panel 4 that constitutes the door panel of the door panel. is fixed.

The lower bracket 11 is arranged in the glass lifting direction (in the embodiment, it is a substantially vertical plane, hereinafter referred to as a vertical plane).
The upper bracket 10 has an adjustment surface 11a that is inclined at an angle α in the clockwise direction in FIG. In the embodiment, the inclined surface 10 is inclined by an angle β in the clockwise direction in FIG.
a, and the long hole 10b is bored in the inclined surface 10a. Note that the angle α may be in the counterclockwise direction, but in this case, the angle β is also in the counterclockwise direction. Also, angle α and angle β shall be less than 90°.

The adjustment bolt 14 is attached at a right angle to the adjustment surface 11a, and is inclined with respect to the horizontal plane (m) by an angle α that is smaller than the angle β, and the fastening bolt 15 is attached with respect to the inclined surface 10a. It is mounted at right angles and is inclined at an angle β with respect to the vertical plane.

The above upper bracket 10 and lower bracket 1
An upper guide rail bracket 12 and a lower guide rail bracket 13 are fixed to the guide rail 2 corresponding to the guide rail 1, respectively.
A contact surface (contact portion) 12a that contacts the adjustment surface 11a and an opposing surface 13a that opposes the adjustment surface 11a are formed, and a hole 1 is formed in the contact surface 12a and the opposing surface 13a.
2b, 13b are drilled and welding nuts 19, 20 are welded to the back surfaces, and the adjustment bolt 14 and fastening bolt 15 are screwed together.

Here, as shown in FIG. 4, the upper bracket 10 to which the fastening bolt 15 is attached is formed with the long hole 10b which is long in the direction of inclination of the inclined surface 10a, and the adjustment bolt 14 is inserted into the upper bracket 10 as described later. When the distance S between the lower bracket 11 and the lower guide rail bracket 13 is adjusted, the contact surface 12a of the upper guide rail bracket 12 can slide along the inclined surface 10a of the upper bracket 10.

Further, as shown in FIG. 5, the adjustment bolt 14 has a collar 14a fixed in the middle and a groove 14b on one end surface into which a tool such as a screwdriver is fitted, and the lower guide of the guide rail 2. After screwing into the welding nut 20 of the rail bracket 13 and adjusting the distance S dimension between the lower bracket 11 and the lower guide rail bracket 13 of the guide rail 2, it is locked with the lock nut 16.

The fastening bolt 15 may be a commonly used hexagonal bolt or the like, and by turning the head 15b, the contact surface 12a of the upper guide rail bracket 12 is brought into at least line contact with the inclined surface 10a of the upper bracket 10, preferably further. Tighten both brackets 10 and 12 so that they are in surface contact as shown in Figure 4.
This is to conclude the following. Note that when the fastening bolt 15 is further tightened from the line contact state, the inner panel 4 and each bracket 10, 11, 12, 13 are deformed, but the angle formed between the inclined surface 10a and the contact surface 12a is small. , the inner panel 4 can absorb the deformation within the elastic deformation of each bracket 10, 11, 12, 13.

In addition, FIGS. 3 and 4 show the lower bracket 1.
1 and the lower guide rail bracket 13
is the standard position (approximately neutral position, which is the ideal state of design values), and in this case, the fourth
In the figure, the inclined surface 10a of the upper bracket 10
and the contact surface 12 of the upper guide rail bracket 12
The figure shows a state in which the two parts a and a are in close contact with each other in surface contact.

Then, the inclined surface 10 of the upper bracket 10
The angle β of a is set larger than the angle α. The angle α is such that the lower adjustment point C of the door glass 1 moves in the vehicle direction and the vertical direction when the above-mentioned distance S dimension is adjusted by advancing and retracting the adjustment bolt 14, and the upper guide rail bracket 12
When the fastening bolt 15 is loosened, the upper bracket 1

0 along the inclined surface 10a.

On the other hand, the door glass 1 moves up and down along the guide rail 2, and the outer panel 3 and the inner panel 4
The opening 30 for door glass formed between the upper end of Sometimes, as shown in Fig. 6, the door glass 1 is brought into close contact with the weather strip 9 fixed on the vehicle body side, and the adhesion between the door glass 1 and the weather strip 9 is determined by adjusting the lower part of the guide rail 2. It is adjusted by an adjustment bolt 14 in the section. Further, the door glass opening 30 is provided with a weather strip 31 that comes into contact with both the inside and outside surfaces of the door glass 1 to seal them.

In this embodiment, as shown in FIG. 2, the upper bracket 10 and the lower bracket 11 are separately fixed to the inner panel 4, but as shown in the prior art shown in FIG. may be formed.

Next, the adjustment operation of the guide rail according to the present invention (in some cases, it may be installed on the production line, and in some cases, it may be readjusted after shipping) will be explained. First, install the guide rail 2 with the door glass 1 attached with the upper guide rail bracket 12 and the upper bracket 10 loosened with the fastening bolts 15, and also tighten the lower guide rail bracket 13 and the lower bracket 11 with the adjustment bolts 14. Temporarily fasten.

Next, with the door glass 1 raised to the highest level, move the adjustment bolt 14 back and forth to optimize the contact and adhesion between the door glass 1 and the weather strip 9. Adjust S between guide rail bracket 13,
At this optimum position, tighten adjustment bolt 1 with lock nut 16.
After locking 4, tighten the fastening bolt 15.

By the way, the adjustment bolt 14 is inclined by an angle α (in the case of a straight line, it refers to a perpendicular line in the perpendicular direction; generally approximately horizontal) with respect to a direction perpendicular to the up-and-down direction of the door glass 1. (Guide rail 2 side) is below the horizontal plane at an angle α
Therefore, when the adjustment bolt 14 is moved forward or backward, the guide rail 2 moves upward and toward the room or downward and toward the outdoors. At the same time, the contact surface 12a of the upper guide rail bracket 12 moves along the inclined surface 10a of the upper bracket 10 while being guided by the elongated hole 10b while maintaining contact with the inclined surface 10a of the upper bracket 10.

In this way, by moving the guide rail 2 in different directions at the two upper and lower points, the door glass 1 also moves in different directions at the two points, the upper adjustment point B and the lower adjustment point C, and as a result, the door glass 1 It rotates approximately around the stationary point A, and while changing the relative position of the stationary point A, which is the center of rotation, with respect to the door glass 1, the stationary point A shown in the figure is rotated with respect to both panels 3 and 4. You can keep the position from moving.

That is, by setting the inclination angle β of the inclined surface 10a and the inclination angle α of the adjustment bolt 14 in this way, by rotating the adjustment bolt 14,
At the stationary point A position in Fig. 2, the upper end of the door glass 1 can be moved in the direction of the vehicle so that no vibration occurs in the direction of the vehicle, and the optimum state as shown in Fig. 6 can be adjusted. .

Hereinafter, the principle of adjusting the guide rail according to the present invention will be described based on FIG. 7. First, the stationary point (rotation center) of the door glass 1 near the door glass opening 30 is designated as A, the upper adjustment point of the guide rail 2 is designated as B, and the lower adjustment point is designated as C, and approximately point A, point B, Assume that point C is on a straight line.

Now, assume that the stationary point A is placed above the upper adjustment point B by a distance p.

Therefore, let us consider a case where the door glass 1 is swung counterclockwise around the stationary point A by a swing angle θ to bring the upper end of the door glass 1 closer to the inside of the vehicle body.

Since the vertical distance between the upper adjustment point B and the lower adjustment point C is q, the distance r between the lower adjustment point C and the stationary point A is set to r=p+q. In order to swing the door glass 1 counterclockwise by the deflection angle θ in FIG. The amount of movement of the upper adjustment point B in the horizontal direction at this time may be approximately p sin θ.

As described above, the inclination of the adjustment bolt 14 of the lower adjustment part forms an angle α, and the lower adjustment point C is moved to the right at right angles to the horizontal direction of door glass elevation.
If it is moved by sinθ, it will also be moved downward by approximately r sinθ tanα in the vertical direction (door glass raising/lowering direction), and the inclined surfaces 10a, 12 of the upper adjustment section
The slope of a forms an angle β, and when the upper adjustment point B is moved horizontally to the right by p sin θ, it is approximately moved downward in the vertical direction by p sin θ tan β.

Here, the guide rail 2 can be regarded as a rigid body,
Lower the lower adjustment point C of door glass 1 r sinθ
When the guide rail 2 is moved by tanα, the entire guide rail 2 moves downward by r sinθ tanα, and therefore the upper adjustment point B also moves downward by r sinθ tanα.

In other words, the vertical movement amount of the upper adjustment point B must be equal to the vertical movement amount of the lower adjustment point C. p sinθ tanβ=r sinθ tanα ∴p tanβ=r tanα In this relational expression, r=p+q Therefore, the seventh As can be seen from the figure, r>p, so it is necessary to make β>α.If angles α and β are determined so that the condition β>α is satisfied, the position of stationary point A can be determined. The distance p to be determined is determined.

That is, from the above relational expression, p tanβ=(p+q)tanα ∴p=q tanα/tanβ−tanα, and p is determined from α, β, and q, and of course r is also determined. On the other hand, if the angles α and β are determined so that the stationary point A can be placed at the desired distance p, then by simply adjusting the adjustment bolt 14 of the lower adjustment part, the upper end of the door glass and the weather You can adjust the strength of the hit with the lip.

The above relational expression is based on the case where the door glass 1 has a linear shape, the upper adjustment point B and the lower adjustment point C are on the vertical line, and therefore the stationary point A of the door glass 1 is also on the vertical line. However, since the door glass 1 is actually a curved glass, the stationary point A of the door glass 1 is not on the center line of the door glass 1, but the p dimension, which is the position of the stationary point A, is approximately the same as above. If it is found by the relational expression, it is practically impossible,
When the door glass 1 is closed, the upper end of the door glass 1 is swung left and right to adjust the contact with the weather strip, and the downward swing of the door glass 1 can be reduced. That is, the stationary point A is a point close to stationary.

In addition, the upper adjustment point B is the door glass opening 3.
If it is far from the line connecting the stationary point A near 0 and the lower center point C, it cannot be simply determined from the above-mentioned relational expression, so the appropriate angle α and angle β
Select.

In the explanation of the above relational expression, the adjustment bolt 14
When the distance S dimension is adjusted by
Since it moves by sinθtanα (=p sinθ tanβ),
The door glass 1 also moves downward (or upward), and the vertical contact between the door glass 1 and the weather strip 9 changes, but the amount of vertical movement of the door glass 1 depends on the regulator. Although this does not cause any inconvenience because they are determined by operating the handle or by operating the power window motor, the angles α and β may be corrected by taking into account the amount of vertical movement.

That is, in the guide rail adjustment mechanism according to this embodiment, the guide rail lower adjustment section is tilted downward, and the upper adjustment section has an inclined surface with a long hole formed therein, so that the adjustment bolt 14 of the lower adjustment section can be moved forward or backward. The upper adjustment part will follow the movement and the desired adjustment will be possible. By appropriately selecting α and angle β, the stationary point A of the door glass 1 can be determined. The upper end of the door glass 1 can be swung inward and outward from the vehicle body centering on the stationary point A of the door glass 1.

In addition, in the present invention, when adjusting the guide rail, the farther the stationary point A of the door glass 1 is from the glass run at the upper end of the door, the more uneven loads are applied to the inner and outer launch channels, which may impair airtightness or Since there are drawbacks such as difficulty in raising and lowering the door glass smoothly, it is desirable that the stationary point A be as close to the glass run at the upper end of the door as possible.

As explained in detail above, the adjustment mechanism for the door glass guide rail according to this embodiment has a simple structure in which the upper and lower adjustment bolt positions that support the guide rail are set at predetermined inclination angles, respectively. The strength of the contact between the upper edge of the door glass and the weather strip on the vehicle body can be easily adjusted by simply moving the adjustment bolt at one location on the lower adjustment part forward or backward, eliminating the need for the troublesome adjustment work required in the past. .

Additionally, when adjusting the guide rail, the stationary point (rotation center) of the door glass can be positioned near the glass run at the top of the door.
This produces effects such as smooth raising and lowering of the door glass without applying unbalanced loads from the inner and outer surfaces of the door glass.
