Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a door window elevating device for elevating and lowering a window glass installed in an automobile door.

(Prior Art) Generally, in this type of door window lifting device, the window glass is slid up and down in the direction of the glass surface (in the vertical direction) by a lifting mechanism installed between the door outer panel and the door inner panel of the door body. Therefore, a structure in which the panel appears and retracts from an opening formed between the upper edges of both panels is widely adopted.

By the way, in order to improve the exterior appearance and aerodynamic characteristics of a car, or to reduce running noise, it is possible to make the outer surface of the car body flush with no protrusions or steps, so-called a flat surface. desired.

However, in the above structure, since the window glass slides up and down between both panels of the door,
The door outer panel is located outside the window glass, and when the window glass is closed, a large step is created between the lower end of the window glass and the upper end of the door outer panel, making it impossible to satisfy the above requirements.

Therefore, conventionally, as a structure to satisfy the above-mentioned request for a flat surface surface, as disclosed in Japanese Utility Model Application Publication No. 51-100428, the upper part of the door outer panel of the door body is bulged outward. A guide is provided that curves outward along the door outer panel, and the guide slides and guides the lower end of the window glass, so that the window glass is raised and lowered while rotating along an outwardly curved curved trajectory. something is proposed.

(Problems to be Solved by the Invention) However, in this proposal, since the door body bulges outward, the door has a special shape, which limits the design of the vehicle body.

The present invention has been made in view of the above points, and its object is to move the above-mentioned window glass along a straight line trajectory extending in the vertical direction of the door in the upper part thereof, and also in the lower part thereof. By moving up and down in curved trajectories that move upward and then move from the inside of the door to the outside of the door, when the window is closed, the window glass surface and the door outer panel surface are flush with each other. The object of the present invention is to make it possible to make the door body into a flat surface without changing the shape of the door body.

(Means for Solving the Problems) In order to achieve this object, the solution of the present invention is such that a door body is formed from a door outer panel and a door inner panel, and a window glass is raised and lowered through an opening in an upper edge of the door body. In an automobile door that is designed to be raised and lowered, a guide mechanism is first provided to guide the raising and lowering of the window glass.
The guide mechanism includes an upper guide extending upward from an upper edge of the door body along at least one of a front edge and a rear edge of the elevating window glass;
A pair of front and rear pairs disposed in the door body below each of the front and rear edges of the elevating window glass, extending upward along the door inner panel of the door body, and then extending in a substantially horizontal direction from the inside of the door body to the outside of the door body. shall consist of a lower guide.

and supporting an upper sliding member slidingly guided by the upper guide on at least one of the upper front edge or the upper rear edge of the elevating window glass;
A lower sliding member that is slidably guided by the lower guide is supported on the lower edge of the elevating window glass, and the lower edge of the elevating window glass is moved from the inside of the vehicle around the upper sliding member near its rising end. It is configured to be raised and lowered by a lifting mechanism so as to horizontally rotate toward the outside of the vehicle.

(Function) With this configuration, in the present invention, the elevating window glass has the upper part of at least one of its leading edge and trailing edge in the upper guide extending above the door body, and the lower parts of the leading edge and the trailing edge in the door body. The front and rear lower guides are slidably supported by a pair of front and rear lower guides via upper and lower sliding members, respectively, and guide the lower part of the front and rear edges of the window glass.
The pair of lower guides are curved so as to extend upward along the inner panel of the door body and then extend in a substantially horizontal direction from the inside of the door body to the outside of the vehicle. When rising through the opening in the upper edge, it rises approximately parallel to the door inner panel of the door body, and when it reaches near the rising end, the lower edge moves toward the inside of the vehicle, centering on the upper sliding member supported by the upper guide. It moves in a horizontal direction toward the outside of the vehicle, and at the raised end position where the window is closed, it comes to rest flush with the door outer panel of the door body.

Therefore, by raising and lowering the elevating window glass while rotating its lower edge horizontally in the vehicle width direction, it becomes possible to create a flat surface of the vehicle body without changing the shape of the door body. It is.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 4 show a case in which the present invention is applied to a side door A of an automobile in which a part of the window is opened and closed, and 1 is a door body consisting of a door outer panel 2 and a door inner panel 3. An upwardly extending portion 1a is formed at the rear upper end of the door body 1. The upwardly extending portion 1a extends upwardly. Further, a fixed window glass 4 is fixed to the upper part of the door body 1 so as to be flush with the door outer panel 2 of the door body 1. The fixed window glass 4
A fixed window glass 4 is located approximately in the front and back center of the lower part, that is, in front of the upwardly extending portion 1a of the door body 1.
A cutout 5 is formed by cutting out a substantially rectangular shape, and an opening 6 through which a movable window glass 10 (described later) can be inserted is formed in a portion of the upper wall of the door body 1 corresponding to the cutout 5. .

The door body 1 has a movable window glass 10.
A guide mechanism is provided to guide the lift up and down. The guide mechanism consists of one upper guide 7 and a pair of lower guides 8 and 9.
is formed in a U-shaped cross section with an open front.
The front edge of the upwardly extending portion 1a of the door body 1, that is, the rear end of the notch 5, extends in the vertical direction of the door A, that is, extends upwardly from the door body 1 along the rear edge of the movable window glass 10. is placed and fixed.

Further, the lower guides 8 and 9 are located inside the door body 1 on a downward extension line of the front edge of the notch 5 of the fixed window glass 4 (below the front edge of the movable window glass 10) and on a downward extension line of the upper guide 7 (below the front edge of the movable window glass 10). The cross-sectional cores are arranged and fixed to face each other in the front and back (below the rear edge of the movable window glass 10), and are open on the rear side for the front lower guide 8 and the front side for the rear lower guide 9. It is formed in a letter shape. And these lower guides 8,
9 extend upwardly along the door inner panel 3 of the door body 1, and then are continuously bent so as to extend substantially horizontally from the inside of the door body 1 toward the outside of the vehicle.

On the other hand, 10 is a movable window glass as an elevating window glass formed in a shape to compensate for the notch 5 of the fixed window glass 4, and a bracket 11 is attached to the rear upper end of the movable window glass 10. A spherical member 12 is attached through the spherical member 12, and an upper sliding member 13 is rotatably coupled to the spherical member 12, and the upper sliding member 13 is slidably fitted into the upper guide 7. . That is, the upper sliding member 1 is slidably guided by the upper guide 7 above the rear edge of the movable window glass 10.
3 is supported.

Further, a glass holder 14 is attached to the lower edge of the movable window glass 10, and brackets 1 are attached to the front and rear ends of the lower edge of the glass holder 14, respectively.
Spherical members 17 and 18 are attached to the front spherical member 17 through 5 and 16, and a front lower sliding member 19 is mounted on the front spherical member 17, and a rear lower sliding member 20 is mounted on the rear spherical member 18, respectively. The front lower sliding member 19 is slidably fitted into the front lower guide 8, and the rear lower sliding member 20 is slidably fitted into the rear lower guide 9. . That is, lower sliding members 19 and 20 are supported at the lower edge of the movable window glass 10 and are slidably guided by the lower guides 8 and 9, respectively.

As described above, the movable window glass 10 is slidably guided by the upper and lower guides 7, 8, and 9, and moves up and down while rotating around its upper edge to open the upper wall of the door body 1. 6, and is configured to be flush with the fixed window glass 4 (door outer panel 2 of the door body 1) at the rising end position, thereby closing the notch 5 of the fixed window glass 4.

Further, on the surface of the door inner panel 3 in the door body 1, an elevating guide 21 extending in the same direction as the elevating direction (vertical direction) of the movable window glass 10 is disposed at a substantially central position between the lower guides 8 and 9. A wire holder 22 having an arcuate cross section and opening toward the outside of the door A is juxtaposed on the rear side of the elevating guide 21. The lifting guide 21 includes a stopper bracket 23, and a roller (not shown) pivotally supported by the bracket 23.
The stopper bracket 23 is connected to the lower part of the glass holder 14 via a link plate 24.
Also, inside the wire holder 22 is a motor 2 fixed inside the door body 1, as shown in FIG.
A wire 26 driven and rotated by the wire holder 2 is slidably inserted through the wire 26, and a part of the wire 26 is inserted into the wire holder 2.
The upper end of the stopper bracket 23 is connected to the stopper bracket 23 through the open portion of the stopper bracket 2. By moving the stopper bracket 23 along the vertical movement guide 21 by driving the motor 25 in forward and reverse rotation, the stopper bracket 23 can be moved. A lifting mechanism 27 is configured to raise and lower the movable window glass 10 that is integrated with the movable window glass 10. Therefore, the movable window glass 10 has the upper sliding member 13 near its rising end.
It is configured to be raised and lowered by a lifting mechanism 27 so that the lower edge horizontally rotates from the inside of the vehicle to the outside of the vehicle.

In addition, 8 and 29 are the lifting guides 2, respectively.
Stoppers attached to the upper and lower ends of the movable window glass 1 regulate the upper and lower end positions of the stopper bracket 23, thereby regulating the range of movement of the movable window glass 10.

Therefore, in the above embodiment, when the movable window glass 10 recessed inside the door body 1 is raised to close the window (notch 5 of the fixed window glass 4), the motor 25 of the lifting mechanism 27 is turned off. For example, when rotated in the forward direction, the wire 26
rotates and the stopper bracket 23 rises along the elevating movement guide 21, and the upward movement of the stopper bracket 23 causes the stopper bracket 23 to rise.
The movable window glass 10 connected to the upper and lower guides 7, 3 via link plates 24
It rises while being guided and supported by 8 and 9 and projects above the door body 1 through the opening 6. Thereafter, when the movable window glass 10 reaches the vicinity of its rising end, the lower edge begins to move from the inside of the vehicle body to the outside in accordance with the curvature of both lower guides 8 and 9, that is, the lower edge begins to move from the upper edge to the upper edge. (upper sliding member 13) while rotating counterclockwise in FIG. Then, the window (notch 5) is closed.

At that time, the movable window glass 10, the fixed window glass 4, and the door outer panel 2 of the door body 1 are all located flush with each other to form a so-called flat surface, so that the appearance of the exterior can be improved by improving aerodynamic characteristics, etc. It is possible to reduce running noise, etc. Further, since the door body 1 can be made into a flat surface without changing the shape of the normal door body 1, there are no restrictions on the design of the vehicle body.

On the other hand, when the movable window glass 10 is lowered to open the window from this closed state, when the motor 25 of the lifting mechanism 27 is rotated in the reverse direction, the stopper bracket 23 is lowered and the movable window glass 10 is opened. As a result, the movable window glass 10 descends while rotating clockwise in FIG. door body 1
The window (notch 5) is opened.

In addition, in the above embodiment, the movable window glass 10
As the lifting mechanism 27 for raising and lowering the window, we used a wire-type electric window regulator in which the wire 26 is driven and rotated by the motor 25, but other types of electric or manual windows such as belt-type, cable-type, arm-type, etc. A regulator may also be used,
The same effects as in the above embodiment can be achieved.

Furthermore, in the above embodiment, the movable window glass 1
Although one upper guide 7 is provided that extends vertically along the rear edge of the movable window glass 10, the upper guide may be arranged so as to extend vertically along the front edge of the movable window glass 10. A pair of front and rear upper guides extending along both front and rear edges of the movable window glass may be provided.

Furthermore, in the above embodiment, the case is described where the application is applied to a partially opening/closing type door A in which a part of the window is opened/closed, but the present invention can also be applied to a normal door in which the entire window is opened/closed. Of course, it can be applied.

(Effects of the Invention) As described above, according to the automobile door window elevating device of the present invention, the upper edge of the window glass is moved in a linear trajectory extending in the vertical direction, while the lower edge is moved toward the door of the door body. Since it is designed to move along a curved trajectory that extends upward along the inner panel and then extends in a substantially horizontal direction from the inside of the vehicle to the outside of the vehicle, there are no design constraints imposed by changing the shape of the door. When the window is closed, the window glass surface and the outer surface of the door body are flush with each other to create a flat surface, which improves the exterior appearance and aerodynamic characteristics of the vehicle while maintaining the existing body shape. This makes it possible to reduce running noise.
