Description

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

(Prior art) Generally, the door glass of a satsuri-less door of an automobile is attached to guide rails installed on the left and right sides via a link mechanism so that it can be raised and lowered vertically.The link mechanism is moved up and down by operating a regulator handle. In order to adjust the contact between the upper end of the door glass and the weather strip attached to the window frame of the car body, when the door glass is closed by tilting it up, a guide rail is installed. The extra edition has been adjusted so that the upper edge of the door glass is tilted inward to improve the adhesion of the leak-proof Etik, etc.

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

In the figure, l is the door glass, 2 is the door glass l, and 1-
These are guide rails for guiding a link mechanism (not shown) that moves up and down in the downward direction, and are installed at two locations before and after 9.

Further, 3 is an outer panel of the door, 4 is an inner panel, and 5 is an inner reinforcing plate fixed to the inside of the inner panel 4.

At the upper and lower predetermined positions of the inner panel 4 marked L.

A sub-adjustment bolt 8a and a main adjustment bolt eb are screwed together in the horizontal direction, respectively, and the sub-adjustment port 8a and main adjustment port 13b are connected to guide brackets 7a and 7b fixed at predetermined positions on the guide rail 2. It is screwed into welding nuts 8a and 8b, and is adjusted to move the sub-adjustment port 8a and main adjustment port eb forward and backward to change the inclination of the guide rail 2, and adjust the upper end of the door glass l to the weather on the vehicle body side. - It is adapted to be brought into close contact with the strip 9. 81a and [llb are nuts for fixing the sub adjustment port 8a and the main adjustment port 6b to the inner reinforcing plate 5, and 82a and 62b are washers.

However, in the conventional adjustment mechanism described above, in order to adjust the upper end of the door glass l so that it comes into close contact with the weather strip 9, two positions are required: the upper secondary adjustment port 6a and the lower main adjustment port eb. Since the method requires repeated adjustment and convergence, adjustment work during door assembly is troublesome and requires a large amount of labor. (Objective of the Invention) The present invention has been made in order to solve the above-mentioned drawbacks of the conventional mechanism, and its purpose is to reduce the adjustment work of the guide rail that guides the vertical movement of the door glass by adjusting the downward adjustment. It is done with one bolt, and the upper edge of the door glass and the weather
To provide an adjustment mechanism for a guide rail for a door glass, which simplifies the work of adjusting the contact with the strip and enables smooth raising and lowering of the door glass to its upper limit.

(Structure of the invention) That is, 2. To achieve the above-mentioned object, the adjustment mechanism according to the present invention includes an upper bracket and a lower bracket formed on the door panel side, and a two-part bracket and a lower part formed on the upper and lower parts of the guide rail that guides the downward movement of the door glass. An H-section guide rail bracket and a lower guide rail bracket are formed corresponding to the brackets, and the upper bracket and the L-section guide rail bracket have inclined surfaces abutting each other, and are adjustable along the inclination of the inclined surfaces with a sub-adjustment port. The lower bracket and the lower guide rail bracket are connected at a main adjustment port so that the interval between the slopes of both brackets can be adjusted, and the main adjustment port and the slopes of the upper bracket are aligned in the same direction with respect to a horizontal plane. The upper bracket is inclined, and the angle of the inclined surface of the upper bracket with respect to the horizontal plane is larger than the angle of the main adjustment port with respect to the horizontal plane.

(Effects of the Invention) Therefore, the door glass guide rail adjustment mechanism of the present invention has a simple structure in which the positions of the upper and lower adjustment bolts that support the guide rail are set at predetermined inclination angles.
Adjustment work is simplified, such as being able to adjust the contact between the upper end of the door glass and the weather strip with a single lower main adjustment bolt.

(Example) Hereinafter, an example according to the present invention will be described in detail based on FIGS. 2 to 6.

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, in the upper and lower predetermined positions inside the inner panel 4,
Upper brackets I and io and lower brackets 1 are fixed, each forming a long hole 10b and a hole 11b into which the sub-adjustment port 15 and main adjustment port 14 are inserted, respectively.

The lower plaquette 1 is arranged in a predetermined direction (second direction) from the vertical plane.
An inclined surface 11a inclined by an angle α in the clockwise direction in the figure
The hole 11b is formed in the inclined surface 11a, and the upper bracket 10 has an inclined surface 10 inclined at an angle β in a predetermined direction (clockwise direction in FIG.
a, and the long hole tab is bored in the inclined surface 10a.

The main adjustment port 14 is attached at right angles to the inclined surface 11a and is inclined at an angle α with respect to the horizontal plane (Q), and the sub-adjustment port 15 is attached at right angles to the inclined surface 10a and is inclined to the vertical plane (Q). It is inclined by an angle β with respect to the

An upper guide rail bracket 2 and a lower guide rail bracket ) 13 are fixed to the guide rails 2 corresponding to the upper bracket 0 and the lower bladder ) 11, respectively, and these guide rail brackets 12 and 13 have the following features:
Slanted surfaces 12a, 13 that have the same slope as the sloped surfaces 10a, 11a and are in contact with the sloped surfaces 10a, lla.
a is formed, and holes 12b and 13b are formed on this inclined surface.
is drilled and welding nuts 18, 20 are welded to the back surface, and the main adjustment port 14 and sub-adjustment port 15 are screwed together.

Here, the 11th part bracket 10 to which the sub-adjustment port 15, which is the 11th part adjustment part, is attached has a +iii elongated hole lOb formed therein, as shown in FIG. When adjusting the adjustment port 14, the adjustment section 1 can partially slide along the mounting surface 10a of the bracket 10.

In addition, as shown in Fig. 5, the h soil adjustment port 14 has a flange 14a fixed in the middle, and a dry/heave etc.
: The nut 2 of the lower guide rail bracket) 13 of the guide rail 2 has a groove portion 14b into which both fit together.
0, and after 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.

I- The sub-adjustment port 15 is made by turning the head 15b with a commonly used hexagonal bolt, etc.
10.
12.

Then, the angle β of the inclined surface 10a of the bracket No. 1 is set larger than the angle α, and the angle α is the door at the lower adjustment part when the above-mentioned distance S dimension is adjusted by moving the main adjustment port 14 forward and backward. The lower adjustment point C of the glass l is designed to move up and down, and when the sub-adjustment port 15 is loosened in the adjustment part of the -A part, the guide bracket 12 (part 1) becomes the elongated hole 10b of the part (bracket) 10. Only dimensions allowed for: Inclined surface IQa of L part bracket to
It is possible to move along.

On the other hand, the door glass l, which is raised and lowered along the guide rail 2, is operated by operating the handle of a regulator (not shown), and when the door glass is raised to the top when the door is closed, it is raised and lowered as shown in Fig. 6. As shown, it is brought into close contact with a weather strip 9 fixedly attached to the vehicle body.

The adhesion between the door glass 1 and the weather strip 9 is adjusted by a main adjustment port 14 in the lower adjustment section of the guide rail 2.

In this example, t! As shown in Fig. S2, the partial bracket 1O and the lower bracket 11 are separately fixed to the inner panel 4, but as shown in the prior art of Fig. 1, they are formed integrally with the inch reinforcing plate 5. Good too.

Next, the adjustment operation of the guide rail according to the present invention will be explained. First, the guide rail 2 with the door glass l mounted thereon consists of a two-part kite rail bracket 12 and a lower guide rail bracket 13 (one part bracket on the door side).
10 and the sub-adjustment port 15 on the lower bracket 11. It is temporarily fixed through the main adjustment hole 4.

Next, the state E with the door glass l raised to the 11th step,
Move the main adjustment port 14, which is the lower adjustment part, back and forth while checking the contact between the door glass l and the weather strip 9 and the electrodeposition so that one end of the door glass l and the weather strip 9 are in close contact with each other. - Adjust the gap S between the lower bracket 11 and the lower guide rail bracket 13 so that the contact and adhesion of the strip 9 is optimal, and after locking the main adjustment port 14 with the lock nut 1B, Lock the adjustment port 15.

By the way, the tip 14c side (guide rail 2 side) of the main adjustment port 14 is inclined downward by an angle α from the horizontal plane, so when the main adjustment port 14 is advanced or retreated, the guide rail 2 moves upward or downward. However, in the upper adjustment part, the inclined surface 12a of the upper guide rail bracket 12 contacts the inclined surface 10a of the upper bracket 10, and the elongated hole 10 in the vertical direction
Since the sub-adjustment port 15 is inserted through b, the inclined surface 12a of the upper guide rail bracket 2 moves on the inclined surface 10a of the upper bracket 10 following the movement of the lower adjustment part.

As a result, the upper part of the guide rail 2 will also move in the left-right direction in conjunction with the vertical movement.

Therefore, by making angle β larger than angle α,
When the door glass 1 is moved in the vertical direction, the amount of movement of the upper adjustment section in the left-right direction is smaller than the amount of movement of the lower adjustment section in the left-right direction. - In the following, the principle of adjusting the guide rail according to the invention will be described with reference to FIG. First, the resting point of the door glass 1 is A,
It is assumed that the upper adjustment point of the guide rail 2 is B and the lower adjustment point is C, and that point A, point B, and point 0 are approximately on a straight line.

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

Therefore, consider the case where the door glass l is swung by a swing angle of 0 around the stationary point A to bring the upper end of the door glass l 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 shake the door glass IT-M2 counterclockwise by the deflection angle θ, assuming that the deflection angle 0 is small, the amount of horizontal movement of the lower adjustment point C is approximately r 5inO
The amount of movement of the upper adjustment point B in the horizontal direction at this time may be approximately set to p gin θ.

As mentioned above, the inclination of the main adjustment port 14 of the lower adjustment section forms an angle α, and the lower adjustment point C is horizontally r
When moving only 5 inb.

It also moves downward by r　ginθ　tanα in the vertical direction.

In addition, the slopes 10a and 12a of the adjustment section form an angle β, and the upper adjustment point B is moved horizontally to the right.
5 inches (if moved by l, vertically downward p
It moves by sinθtanβ.

Here, the guide rail 2 can be regarded as a rigid body, and when the lower adjustment point C of the door glass l is moved downward by r sin θ tan α, the entire guide rail 2 is moved downward by r 5 inches.
Only Otanα moves.

Therefore, the upper adjustment point B also moves downward r sinθ tanα
move only.

In other words, ■ - the amount of vertical movement of the lower adjustment point B is the lower adjustment point C
p 5inOtanβ= r 5inOtanαp t
anβ=rtanα In this relational expression, r=p+q Therefore, as can be seen from Figure 7, r > p, so it is necessary to set β>α, and the angle α and angle β
If we determine this, the distance p that determines the position of the stationary point A will be determined.

In other words, from the relational expression 1- p tanβ=(p+q) tanα ・'-p=tanα tanβ-tanα Then, 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 main adjustment pole [4] of the lower adjustment part, the bottom end of the door glass and , the strength of contact with the weather strip can be adjusted.

The above relational expression assumes that the door glass l has a linear shape, and that the partial adjustment point B and the lower adjustment point C are on the vertical line H, and therefore the stationary point A of the door glass l is also on the vertical line H. However, since the door glass l is actually a curved glass, the stationary point A of the door glass l is not on the center line of the door glass l, but the two dimensions that are the position of the stationary point A are approximate. In practical terms, if you use the above relational formula, it is practical to adjust the contact with the weather strip by swinging the edge of the door glass L left and right when the door glass is closed.
The downward swing of can be reduced. That is, the stationary point A is a point close to stationary.

In the explanation of the above relational expression, when the distance S dimension is adjusted by the main adjustment port 14, the entire guide rail 2 moves downward (or upward) r s:nOtanct (=
p5inOtanβ), the door glass l also moves downward (or in the L direction), and the contact between the door glass l and the weather strip 9 in the downward direction changes. The amount of downward movement of L is determined by operating the regulator handle.
Alternatively, since it is determined by operating the power window motor, it does not cause any inconvenience.

In other words, the guide rail adjustment mechanism according to this embodiment is as follows:
The guide rail lower adjustment section is tilted downward, and the upper adjustment section has an inclined surface with a long hole, so simply by moving the main adjustment bolt 14 of the lower adjustment section forward or backward, the upper adjustment section will follow, making the desired adjustment. is possible, and by appropriately selecting the angle α and the angle β based on the vertical interval dimension q between the E part adjustment point B of the door glass l of the upper adjustment part and the lower adjustment point C of the lower adjustment part, The stationary point A of the door glass l can be determined. Then, one end of the door glass 1 can be swung to the inside and outside of 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 further away the stationary point A of the door glass l is from the glass run at one end of the door 1, the more uneven loads are applied to the inner and outer launch channels, and the airtightness is impaired. Or the door glass,
It is desirable that the stationary point A be as close to the glass run at one end of the door 1 as possible, since there are drawbacks such as difficulty in smoothly raising and lowering the door.

As explained in detail above, the door glass guide rail adjustment mechanism according to the nine embodiments adjusts the positions of the upper and lower adjustment bolts that support the guide rail.

It has a simple structure in which each part is set to a predetermined inclination angle, and the door glass 1: edge and vehicle side weather can be easily adjusted by simply moving the adjustment bolt in one position of the lower adjustment part forward and backward.
Since you can adjust the strength of contact with the strip,
The troublesome adjustment work required in the past is no longer necessary.

Further, when adjusting the guide rail, the stationary point of the door glass that is set can be located near the glass run at the end of the door L, so that no unbalanced loads are applied from the inner and outer surfaces of the door glass.

This provides effects such as smooth raising and lowering of the door glass.
