Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a door glass lifting device attached to an automobile door, and more particularly to a door glass lifting device suitable for a door having a notch corresponding to a wheel arch.

[Conventional technology]

Generally, the door glass of an automobile can be opened and closed by being raised and lowered linearly by a door glass lifting device attached to the door. By the way, in the case of a rear door of a four-door car that has a notch 1a corresponding to the wheel arch at the bottom of the door panel 1 as shown in FIG. 6, the lower edge of the door glass 2 protrudes rearward and extends above the notch 1a. If the window is facing the window, the door glass 2 can only be lowered to the position of the notch 1a, and the window cannot be opened completely. Therefore, when opening the window, a technique is known in the art in which the door glass 2 is lowered in an inclined position in which the rear portion on the side of the notch 1a is high and the front portion is low (see Japanese Utility Model Publication No. 17896/1987).

[Problem that the idea aims to solve]

According to the prior art described in the above publication, when the vertical width of the door glass 2 is relatively small, the window can be opened completely, but when the vertical width of the door glass 2 is large, the window can be opened completely, as shown in FIG. As shown, there was a problem in that the rear upper edge of the door glass 2 remained protruding into the open window space above the door panel 1. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a door glass lifting device that can completely open a window even when the lower edge of the door glass largely extends to the notch of the door panel.

[Means to solve the problem]

To achieve this objective, the present invention is attached to a door panel having a notch corresponding to the wheel arch, the main glass has a lower edge located in front of the notch, and the lower edge is located above the notch. A door glass lifting device that lifts and lowers a door glass that is divided into a sub glass and a regulator device that lifts and lowers the main glass, and a regulator device that is fixed to the front edge of the sub glass and extends in the vertical direction, and is fixed to the main glass. The sub-guide rail includes a sub-guide rail that engages with the sub-guide pin, and a main guide rail that forms part of the regulator device, extends in the vertical direction, and engages with the main guide pin attached to the sub-guide rail, The guide rail is provided with a locking device that removably engages with a locking pin fixed to the main glass and the main guide rail, and this locking device engages with the locking pin within the raising and lowering range of the sub-glass and is connected to the main guide rail. At the same time, after the sub-glass has been lowered and accommodated in the door panel, the lock pin is disengaged and engaged with the main guide rail.

[Effect]

According to the door glass lifting device employing such means, the locking device engages with the lock pin and disengages from the main guide rail within the range of lifting and lowering the sub-glass, so that the main glass can be lifted by operating the regulator device. and the sub-glass are raised and lowered as one. After the sub-glass is lowered and housed in the door panel, the locking device disengages the lock pin and engages the main guide rail, so when the regulator device is lowered, the sub-glass stops descending and the main guide rail is engaged. Only the glass is lowered and accommodated within the door panel, thus completely opening the window above the door panel.

【Example】

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. In FIGS. 1a to 1c, which schematically shows the structure of a door glass lifting device according to an embodiment according to the lifting and lowering positions of the door glass, reference numeral 1 indicates a door panel having a notch 1a corresponding to a wheel arch, and reference numeral 2 indicates a door panel having a cutout portion 1a corresponding to a wheel arch. The door glass 2 has a substantially square main glass 2a whose lower edge is located in front of the notch 1a, and a substantially triangular sub-glass 2b whose lower edge is located above the notch 1a. It is divided into parts. The main glass 2a is raised and lowered by a handle operation (not shown) by a regulator 3 having an X-link configuration.
has a main guide rail 4 extending in the vertical direction. As shown in FIGS. 2 and 3, a sub-guide rail 5 extending in the vertical direction is fixed to the front edge of the sub-glass 2b. A locking device 6 and a main guide pin 7 are fixed to the sub-guide rail 5 side by side on a suitable support plate located near the lower edge of the sub-glass 2b and protruding forward. It is located on the front side of the vehicle body relative to the lock device 6. On the other hand, a pair of upper and lower sub-guide pins 8, 8 that engage with the sub-guide rail 5 and are relatively movable up and down are fixed to the rear edge of the main glass 2a. A lock pin 9, which is removably engaged with the lock device 6, is fixed to the lower edge of the main glass 2a adjacent to the lower sub-guide pin 8. The main guide rail 4 is adapted to operate the regulator 3 by engaging with a main guide pin 7 fixed to the sub-guide rail 5, and has a lower end that contacts the lower surface of the locking device 6. A lock stopper 4a that can be contacted is provided protrudingly. 4 and 5 show the internal structure of the locking device 6, which has grooves that are open in the side surface and the bottom surface that slide against the main guide rail 4 and extend in the vertical direction. base 6a
and a cover 6f having a cutout groove open at the bottom.
A cam stopper 6b, a spring 6c, a cam 6d, and a cam pin 6e are built in the internal space between the two. The cam stopper 6b is urged downward by a spring 6c in a state where it is not removed, and the lock pin 9 fixed to the main glass 2a enters upward from the openings of the base 6a and cover 6f as shown in FIG. 5a. If this occurs, the robot can come into contact with this and retreat upward by a predetermined amount. The cam 6d is a substantially right triangular member rotatably supported by a cam pin 6e, and when the cam stopper 6b is retracted upward as shown in FIG. 5a, the cam 6d is turned inside (counterclockwise in FIG. The main guide rail 4 is rotated to release the engagement with the main guide rail 4 as shown in FIG. 5b.
When it faces the engagement hole 4b provided directly above the lock stopper 4a, it rotates outward (clockwise in FIG. 5) as the cam stopper 6b descends, enters the engagement hole 4b, and connects to the main guide rail 4. It's starting to engage. Next, the operation of the door glass elevating device of one embodiment configured as described above will be explained. First, as shown in FIG. 1a, the main glass 2a
When the window is fully closed and the sub-glass 2b is at its upper limit position, the lock pin 9 fixed to the main glass 2a enters the lock device 6 as shown in FIG. 5a and retracts the cam stopper 6b upward. I'm letting you do it. At this time, the main guide rail 4 is lowered relative to the locking device 6, so the cam 6d is pushed by the side surface of the main guide rail 4 and rotates inward, causing the cam stopper 6b to rotate inward.
In other words, the locking device 6 engages with the locking pin 9 to vertically connect the main glass 2a and the sub-glass 2b, and the locking device 6 also holds the main guide rail 4.
Since the main glass 2a and the sub glass 2b are disengaged from each other and allow relative movement of the sub glass 2b, the lowering operation of the regulator 3 causes the main glass 2a and the sub glass 2b to move.
and descend as one. Here, when the sub-glass 2b is lowered to the position where it is accommodated in the door panel 1 as shown in FIG. 1b,
The main guide rail 4 rises relative to the lock device 6, bringing its lock stopper 4a into contact with the lower surface of the lock device 6, and causing its engagement hole 4b to face the cam 6d of the lock device 6. Then, when the regulator 3 is continuously lowered, the lock pin 9 fixed to the main glass 2a moves downward while pushing the cam 6d as shown in FIG. It rotates and enters the engagement hole 4b of the main guide rail 4. In this way, the lock device 6 engages with the main guide rail 4 and disengages from the lock pin 9, so that the sub-glass 2b stops descending from then on.
Only the main glass 2a is lowered and accommodated in the door panel 1 (see FIG. 1c). Therefore, even if the lower edge of the door glass 2 largely extends to the notch 1a of the door panel 1 corresponding to the wheel arch, the window above the door panel 1 can be completely opened. Note that when the regulator 3 is raised from the fully open state of the window, the main glass 2a is moved upward at the position shown in FIG.
The lock pin 9 fixed to the lock pin 9 enters the lock device 6 and retracts the cam stopper 6b upward, and then the main guide rail 4 descends relative to the lock device 6, causing the cam 6d to rotate inward. Since the main glass 2a and the sub-glass 2b move up to the state shown in FIG. 5a, the main glass 2a and the sub-glass 2b move up as one.

[Effect of the idea]

As explained above, according to the present invention, the locking device engages with the locking pin and disengages from the main guide rail within the raising/lowering range of the sub-glass, so that the main glass and the sub-glass can be integrated into one body by operating the regulator device. It is raised and lowered. After the sub-glass is lowered and housed in the door panel, the locking device disengages the lock pin and engages the main guide rail, so when the regulator device is lowered, the sub-glass stops descending and the main guide rail is engaged. Only the glass is lowered and accommodated within the door panel. Therefore, even if the lower edge of the door glass extends to a notch in the door panel corresponding to the wheel arch, the window above the door panel can be completely opened.
