Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a door glass surface unifying device in a window regulator.

BACKGROUND ART A device of this type is disclosed in Japanese Utility Model Application Publication No. 194078/1983. This involves wiring a cable that moves when the lift handle is activated along a guide rail for raising and lowering the window glass provided on the door, and attaching it to a stopper on the door side at the upper edge of the window glass located above the guide rail. A link mechanism is provided on the lower edge of the window glass that pulls the window glass inward from the furanone surface state by engagement between the stopper and the projection piece when the window glass is lowered, The present invention is characterized in that a slider is connected to the guide rail and connected to the cable.

In addition, as a structure different from this, Utility Model No. 59-1
There is one disclosed in Japanese Patent No. 57917.

A door panel is formed by an outer panel and an inner panel, and a window glass that can be raised and lowered is housed between the outer panel and the inner panel. A sliding member that slides in contact with the member is attached, and the upper end of the guide member is bent toward the outside of the vehicle body,
The lower end of the window glass is bent toward the interior of the vehicle from near the top of the belt line position when fully open.

Problems to be Solved by the Invention However, the above-mentioned conventional method is
In the case of No. 94078, 1. First, if the door is forcefully closed with the window glass partially open, the link mechanism is bent between its fulcrums, so the shock causes the vehicle body to violently sway in and out. This is more likely to cause damage to the window glass.

Second, near the highest position of the window glass, each time the window glass is raised or lowered, the protrusion on the window glass side overcomes the stopper on the door side, which increases the operating force when opening and closing the window glass, improving operability. The disadvantage is that it decreases.

Thirdly, the protruding piece and the stopper must be engaged before the link mechanism bends, otherwise the window glass will have to descend without being drawn into the room. However, since it is impossible to reliably increase the engagement force between the protrusion and the stopper from the viewpoint of mechanism and operability, there is a drawback that reliability in operation is low.

Moreover, the latter, disclosed in Japanese Utility Model Application No. 59-157917, has the disadvantage that the windshield also requires a lath and a lock knob that must be bent.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides guide rails for guiding and regulating the vertical movement of the door glass, and that guide rails are provided inside the door at the front and rear, and the guide rails and the door glass are connected by a link mechanism. In the door glass surface unifying device of a window regulator connected via The upper and lower pins of each link mechanism are held by the corresponding guide rails, and each link is pivotally connected to the door glass side. A roller is pivotally attached to the upper part of the door glass, and the roller is held by another guide rail extending vertically within the door frame.

Operation The door glass moves up and down due to the operation of the window regulator.

In the case of upward movement, the links of the link mechanism move in parallel while the upper and lower pins move upward along the guide rail, and eventually tilt toward the outside of the vehicle body when the upper pins reach the inclined guide portion. Meanwhile, the roller of the door glass also rises along the guide rail in the door frame and reaches the upper end of the door frame.

After the door glass roller reaches the upper end of the door frame, the door glass rotates toward the outside of the vehicle body using the guide roller as a fulcrum at its highest position, and as a result, the surface between the door glass and the outer surface of the door - transformation is done.

Conversely, in the case of downward movement of the door glass, the pin is urged downward in the guide rail and leaves the inclined guide part. As a result, the door glass initially moves toward the inside of the vehicle. Then, it moves downward and the window is opened.

Example 1 to 6 show one embodiment of the present invention.

In these figures, reference numeral 1 denotes a door glass, and a vehicle door equipped with the door glass 1 is provided with a window regulator assembly 4 between a door outer panel 2 and a door inner panel 3. Further, a door molding 5 is provided at a portion of the door outer panel 2 that contacts the door crow 1.

Inside the door, on both sides of the assembly 4 are guide rails 6 for guiding and regulating the vertical movement of the door glass 1.
is provided. Each guide rail 6 has a U-shaped cross section, and its groove 7 faces the assembly 4 side.

Further, each guide rail 6 is provided with an inclined guide portion 8 inclined toward the outside of the vehicle body at its upper portion, and this portion is connected to the groove 7.
extends outward from the vehicle body. The upper end is closed with an end wall 9, which serves as a stopper for a pin, which will be described later.

Each of the guide rails 6 and the door glass 1 are interconnected via a link mechanism, and the door glass 1 and the window regulator assembly 4 are also interconnected via the link mechanism.

Therefore, the drive of the window regulator 4 is controlled by the guide rail 60 through the link mechanism, and the door glass 1 is
It appears as a vertical movement.

Each link mechanism includes pins 11 and 12 pivoted on the upper and lower sides of a substantially dogleg-shaped link 10 that extends in the vertical direction of the guide rail 6, and these upper and lower pins 11 and 12 correspond to each guide rail 6. It fits into the groove 7 of. The doglegged link 10 is installed in a dogleg shape projecting outward from the vehicle body, and is pivoted at its bent portion to a bracket 14 fixed to a holder 13 of the door glass 1. Code 15 is the force 7 mepin for this pivot connection.

Although the above-mentioned bracket 14 is separate from the glass holder 13 and is connected and fixed by a screen 16, it may be integrally molded.

The doglegged link 10 of the link mechanism and the regulator assembly 4 are connected with a lift arm bracket 17 interposed therebetween. Reference numeral 18 indicates screws for fixing the doglegged link 10 to both the front and rear ends of the wrist arm brace 170, respectively.

The guide rail 6 is fixed to the door inner panel 3 by a stan dowel bolt 1, and its position in the interior and exterior directions of the vehicle body can be adjusted by turning this stud bolt 19.

A roller 20 is pivotally attached to the upper part of the door glass 1 as shown in FIGS. 5 and 6.
is a guide rail 22 that extends vertically within the door frame 21.
is maintained. Note that the reference numeral 23 is a center pillar.

In this case, the roller 20 is rotatably attached to the tip of a shaft 24 fixed at right angles to the door glass 1.

Therefore, as the door glass 1 moves up and down, the roller 20 rotates around the shaft 24 and moves up and down along the guide rail 22, which prevents the door glass 10 from swinging in and out of the vehicle body. In particular, when the door glass 1 reaches its highest position, the upper end of the door glass 1 must be positioned.

Therefore, the door glass 1 is
To close the regulator assembly 4, the lift arm bracket 17 is moved in the direction of arrow A (FIG. 1) by driving the regulator assembly 4 by a handle or a motor. Along with this, the link 10 also connects to the guide rail 6 via the pins 11 and 12.
It ascends in a constant posture while being subject to the following regulations (Figure 3).

Then, when the upper pin 11 moves within the inclined guide section 8, the roller 20 is located at the upper end of the guide rail 22.

As a result, the door glass l rotates in the direction of the outside of the vehicle body in the direction of arrow B about the roller 20 as a fulcrum, and comes into close contact with the door molding 5 to be flush with the outer surface of the door.

Conversely, in order to open the door glass 1, the regulator assembly 4 may be driven in the opposite direction to that described above. As a result, the upper pin 11 separates from the inclined guide portion 8 and draws the door glass 1 toward the interior of the vehicle as indicated by arrow C. After that, the upper and lower pins are 11.121! - They descend in a row along the guide rail 6, and the door glass l opens without colliding with the door molding 5 or the like.

Next, FIGS. 7 and 8 show other embodiments of the present invention.

In this case, the wind legierator 7 assembly 4 in the above embodiment is of an arm type, but is of a wire type.

In these figures, reference numeral 25 denotes an endless wire, which is passed through the door handle 27 in an N-shape to pulleys 26 installed two above and below inside the door.

Then, the bracket 15 of the glass holder 13 is pivoted to the doglegged link 10 with a caulking pin 15, and
0 is fixed to the wire 25 at its lower pin 12 by a fixture 28 coaxially connected to the pin 12.

Therefore, in order to close the door glass l, it is sufficient to turn the handle 27 in the direction of the arrow mark and make the wire 25 run in the direction of the arrow E. By doing this, the doglegged link 10 is moved along the guide rail 6. It rises in the direction of arrow F from the broken line position to the solid line position (FIG. 7). Then, as in the embodiment described above, when the pin 11 enters the inclined guide portion 8, the door glass 1 rotates toward the outside of the vehicle body using the roller 20 as a fulcrum, and becomes flush with the outer surface of the door.

Effects of the Invention Since the present invention is constructed as described above, the door glass is supported vertically by rollers and pins, and even when the door glass is in a half-open state, it is supported by at least two pins, upper and lower, so that the strength of the door is improved. The door glass does not shake sideways even when it is quiet.

In addition, since the door glass is flushed and removed from the flush by relative movement under engagement between the pin and the guide rail, the door glass can be sharpened smoothly and has excellent operability. Moreover, the reliability of the operation of the door glass can be improved compared to the conventional one.

Furthermore, since the weight of the door glass can be supported by the inclined guide portion of the guide rail when the door glass is fully closed, it is possible to avoid applying excessive force to the regulator 7 assembly.
