Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door glass opening/closing mechanism for automobiles, particularly luggage automobiles.

In recent years, especially for luggage vehicles, improvements have been made to improve the driver's visibility, especially for the door on the opposite side of the driver, in order to ensure safety by preventing left-turn accidents involving pedestrians, etc., and to make it easier to identify pedestrians when driving. There is a strong demand for improved visibility, and one way to widen the field of view is, for example, by expanding the door glass 6 downward in the driver's seat section 1 shown in FIG. One possible method is to widen the driver's visibility, but in this case, for luggage vehicles, especially cab-over trucks,
As shown in FIG. 2, the arrangement of the driver's seat section 1 and
The shape of the lower part of the door is inevitably restricted by the wheel portion and has an arcuate portion 2', making it impossible to store the enlarged door glass 6 in the door glass storage section 4 as described above.

Therefore, as another example, as shown in FIG. 3, when the door glass 6 is enlarged, the door glass 6 that cannot be stored in the door glass storage section 4 is divided and fixed to the upper part of the door, so that only the part that can be stored is divided. It is conceivable that the door glass be stored in the door glass storage section 4.
In this case, since the opening area of the glass portion is reduced, there are drawbacks such as insufficient introduction of outside air, especially in summer, and difficulty in emergency escape through the door opening 3 in the event of an accident.

This invention was devised in view of these circumstances.
The door glass is not made of one piece as in the past, but is composed of two pieces of door glass, the first door glass and the second door glass, and a diaphragm is added in the width direction at the middle position of the door sash to increase the width above and below the diaphragm. By changing the dimension in the direction and making the width of the lower part approximately twice that of the upper part,
In the area below the throttle part, the first door glass and the second door glass move up and down independently in a multi-layered state, and in the part above the throttle part, the first door glass and the second door glass move up and down independently. By configuring the two layers to be able to engage each other and move up and down, it is possible to expand the overall field of view through the door glass, and when necessary, both door glasses can be moved up and down. The above-mentioned problem is solved by making it possible to store it in a glass storage section.

Hereinafter, embodiments of the present invention will be explained with reference to FIGS. 6 to 12. 7 is inside the driver's seat section 1 and the door glass storage section 4

and a second roller 22 are each rotatably attached to the shaft, and the first roller 21 and the second roller 22 are attached at an interval substantially equal to the length of the upright portion 19a described above. By rotating the regulator handle 7 clockwise or counterclockwise, the tips 23 and 24 of the first and second links 15 and 16 move along the guide frame 19. Furthermore, the first roller 21 is located outside the guide frame 19 in a first channel 25 that is horizontally arranged parallel to the lower horizontal portion 19c, and the second roller 22 is located directly below the first channel. A second channel 26 arranged parallel and horizontally
They fit into each other so that they can slide in the long side direction.

On the other hand, of the first door glass 27 and second door glass 28 stored in the door glass storage part 4 in a layered state, the sash 29 fitted onto the lower end of the first door glass 27 on the inside side is tilted downward. A recess 32 is formed by the locking portion 30 protruding approximately L-shaped in cross section and the lower edge of the base 31, and a plurality of through holes 33 are formed in the locking portion 30 along the long side direction. , elastic hooks 34 fixed to the outer upper part of the first channel 25 are respectively locked.

Further, a first glass plate is provided at the upper end of the second door glass 28.
As shown in FIG. 1, a sash 35 is fitted into the sash 35, and a convex portion 36 is formed inwardly above the fitting portion 37 with a gap 38 in between. It has a shape that can fit into the recess 32 of 35.

Further, a sash 39 is fitted to the lower end of the second door glass 28, and the sash 39 and the second channel 26 are connected by a connecting spring 40 whose side surface is shaped like a fishhook.

The first door glass 27 and the second door glass 28 are, as shown in FIGS. 4 and 5, a pair of door sashes disposed opposite each other from the door glass storage section 4 to the upper door opening 3. 11 and 12, the door sash 5 is placed in an intermediate position, that is, near the upper edge 4a of the door glass storage section 4, as shown in FIGS. 11 and 12. As shown, the first door glass 27 and the second door glass 28 are arranged horizontally in the door glass storage section 4 below the narrowing section 41. The first door glass 27 or the second door glass 28 is housed in a multi-layered state in the direction and has a width sufficient to allow each to be raised and lowered. It is formed to have a width sufficient to allow one of them to move up and down independently. The upper horizontal portion 19b of the guide frame 19 is located slightly below the constricted portion 41 of the door sash 5, that is, below the locking portion 30 by a dimension substantially equal to the height of the locking portion 30.

Next, the operation mode of the door glass opening/closing mechanism in this embodiment will be explained. First, as shown in FIG. 7, the first door glass 27 and the second door glass 28
When the driver in the driver's seat section 1 continuously rotates the regulator handle 7 clockwise while the door glass storage section 4 is housed in the multilayer state, the first
As shown in FIG. 0, the sector gear 9 meshed with the sprocket gear 8 rotates counterclockwise, and as a result, the swing arm 10, which has its rear end 11 fixed to the sector gear 9, rotates around the shaft 12. As it rotates counterclockwise, the shaft 14 of the tip 13 advances and is further displaced upward, so the first link 15 is pushed up and the pin 17 is inserted into the guide hole 20 in the upright portion 19a of the guide frame 19. As the first roller 21 also rises along with the pin 17, the first roller 2
The first channel 25 into which the door sash 1 is fitted and the first door glass 27 which is engaged with the first channel 25 by the elastic hook 34 move up along the door sash 5 in conjunction with each other.

When the first roller 21 reaches the upper corner portion 19d where it transitions from the upright portion 19a to the upper horizontal portion 19b, the first door glass 27 does not rise any further and then becomes horizontal along the upper horizontal portion 19b. At this stage, the locking portion 30 at the lower end of the first door glass 27 is stopped at the position of the constriction portion 41 of the door sash 5 based on the positional relationship between the upper horizontal portion 19b and the door sash 5. . On the other hand, the second link 16 is pulled as the shaft 14 of the tip 13 of the swing arm 10 advances and is further displaced upward, so the pin 18 is pulled as shown in FIG.
The second roller 22 attached to the pin 18 moves horizontally along the guide hole 20 in the lower horizontal portion 19c, and the second roller 22 attached to the pin 18 moves within the second channel 26 while the pin 18 is moving in the lower horizontal portion 19c. rolling, first
At the stage when the pin 17 of the link 15 is displaced from the upright portion 19a to the upper horizontal portion 19b via the upper corner portion 19d, the pin 18 of the second link 16 is displaced from the lower horizontal portion 19.
The second roller 22 rises accompanied by the second channel 26 as the second roller 22 moves from the lower corner part 19e to the upright part 19a and begins to rise. That is, in conjunction with the movement of the first roller 21 from the upper corner portion 19d to the upper horizontal portion 19b, the second roller 22 moves from the lower horizontal portion 19c to the lower corner portion 19e to the upright portion 19a. 1 door glass 2
7 stops rising, the second door glass 28 connected to the second roller 22 via the second channel 26 and the connection panel 40 begins to rise instead. Then, when the second door glass 28 rises and the convex portion 36 provided at the top reaches the position of the constriction portion 41 of the door sash 5, the convex portion 36
At the same time as it rises, it moves inward along the constriction part 41, that is, to the position shown by imaginary lines 42 and 43 in FIG. 30 is pressed inward, the elastic hook 34 is removed from the through hole 33, and the connection between the first door glass 27 and the first channel 25 is released. Therefore, after this stage, the first door glass 27 is supported by the second door glass 28.
In the stacked state of the tiers, they begin to rise in conjunction with the rise of the second door glass 28.

Note that as the convex portion 36 moves into the concave portion 32, the lower part of the second door glass 28 also moves inwardly by bending the connecting spring 40, so that the second door glass 28 can be raised without any trouble. . While the second roller 22 is moving to raise the second door glass 28, the first roller 21
The first channel 25 rolls along with the displacement of the first channel 25 . Thereafter, the second door glass 28 rises to a position where the second channel 26 into which the second roller 22 is fitted contacts the lower edge of the first channel 25 located directly above the second channel 26, and then stops. However, at this position, the first layer is stacked in two layers.
By the door glass 27 and the second door glass 28,
The size of the door opening 3 is determined so that the door opening 3 is completely sealed.

Further, when the first door glass 27 and the second door glass 28 that have been raised to the top as described above are lowered and stored in the door glass storage section 4, the sprocket gear 8 is moved by the regulator handle 7. If the sector gear 9 is rotated counterclockwise and the sector gear 9 is rotated clockwise, the first door glass 27 and the second door glass 28 are rotated through the reverse process of the operation described above.
can be stored.

The present invention has the first door glass and the second door glass as described above.
The two door glasses of the door glass are stored in a multi-layered state in the door glass storage section, and when raised and lowered at the door opening, the door glass is configured to be stacked in two layers. The glass storage area only needs to be approximately half the size of the door opening, and the opening area of the door glass can be expanded, significantly improving visibility to the side of the driver's seat, and thereby preventing pedestrians when turning left. It is possible to prevent accidents that may occur to bicycles or bicycle riders, and because the opening area can be kept large, it is also effective for introducing outside air and for emergency evacuation in the event of an accident involving the vehicle itself. In addition, it is possible to completely store the entire door glass in the small storage space, and by drilling guide holes in the guide frame, the first link, the second link, the first roller, and the second roller are connected to each other. Since the connecting pins slide while being guided by the guide path holes, the respective pins do not rattle, and accordingly, the operation of either the first link or the second link or the first roller or the second roller is prevented. Since the opening/closing operation of the door glass can be carried out smoothly, the opening/closing operation of the door glass can be carried out extremely smoothly and continuously, and it has an epoch-making effect as a door glass opening/closing mechanism for automobiles, especially luggage cars.
