As shown in FIG. 6, in the glass elevating / lowering device 1, the support shaft 11 is fixed to the inner panel 10.
And the guide channel 15. And roller 5,
14, 16 and the pivot 13 can move. With such a structure, in the glass elevating / lowering device 1, by the rotation of the pinion 8 connected to the driving shaft 7, the force is transmitted in the order of the sector gear 6 and the main arm 3, and the rotation of the pinion 8 of the main arm 3 is transmitted. It is converted into swinging about the support shaft 11.

FIG. 5 shows the locus of the roller 5 attached to the tip of the main arm 3. As shown in the figure, the roller 5 takes a locus as shown by the alternate long and short dash line a with the support shaft 11 as the swing axis. At this time, the bottom channel 2 also moves up and down while maintaining the horizontal posture, the rollers 5 and 14 slide laterally on the guide rail 2a of the bottom channel 2, and the roller 16 guides the guide channel 15 to the guide channel 15.

[0008]

The glass lifting device 1 is
As described above, it is an X-arm type link mechanism, and basically this mechanism is a plane sliding type. Then, as shown in FIG. 6, the main arm 3 of the X-arm type glass lifting device 1
The sub arm 12 is a straight line. In addition, many side glasses of recent automobiles have a curved surface with a radius of 1000 mm to 3000 mm. Therefore, when the glass 17 is moved up and down, the width of the offset H shown in FIG. 6 changes.

Therefore, when a person manually turns the regulator handle to move the glass up and down, the width of the offset H changes, so that the X arm is bent and the regulator handle operation cannot be performed smoothly. Further, when a flat link mechanism is mounted on a curved glass inside an automobile door, the gap W between the glass lifting device 1 and the glass 17 is widened as shown in FIG. 7, which is disadvantageous in layout.
Further, since a biased force is applied to the glass, the glass is distorted and the appearance of the automobile is not good.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a glass elevating device that can smoothly elevate and lower the glass of an automobile and saves space in layout. To do.

[0011]

SUMMARY OF THE INVENTION The above object is to provide an X-arm type in which a main channel and a sub-arm are engaged with a bottom channel for guiding up and down of a glass of an automobile, and the main arm and the sub-arm are crossed. In the glass lifting device, the main arm and the sub arm are curved along the curved surface of the glass.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A glass lifting device according to an embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted. Further, the operation of the glass elevating device is the same, so the description thereof will be omitted.

FIG. 1 shows an X-arm type glass raising / lowering device 21 according to the present invention. The glass lifting device 21 includes a support shaft 11, a guide channel 15, and a base plate 18.
Is fixed to an inner panel of a side door of an automobile (not shown). The sector arm 6 is attached to an end of the main arm 23, and the main arm 23 can be swung about the support shaft 11 as a central axis. An arm portion 23a from the support shaft 11 of the main arm 23 to its tip is curved in an arc shape toward the outside of the automobile. The roller 5 is attached to the tip of the main arm 23,
The roller 5 is slidably fitted to a guide rail 2a provided on the bottom channel 2.

The sub-arm 24 of the glass elevating / lowering device 21 comprises a first arm piece 24a and a second arm piece 24b, and the roller 14 is attached to one end of the first arm piece 24a. The roller 14 is slidably fitted to a guide rail 2a provided on the bottom channel 2. The other end of the first arm piece 24 a has a pivot shaft 26 provided on the main arm 23.
Is pivoted to. One end of the second arm piece 24b is pivotally supported by a pivot shaft 26 provided on the main arm 23, as with the first arm piece 24a. Also, the second arm piece 24b
The roller 16 is attached to the other end, and the roller 16 is slidably fitted to the guide rail 15a provided in the guide channel 15. Like the main arm 23, the sub arm 24 is curved in an arc shape toward the outside of the vehicle.

FIG. 2 shows a state in which the bottom channel 2 of the glass raising / lowering device 21 of the present embodiment is lowered to the maximum, and FIG. 3 shows a state in which the bottom channel 2 is raised to the maximum. The curvatures of the curved surfaces of the main arm 23 and the sub arm 24 are as shown in the figure.
The curved surface 4 has a curvature that is substantially the same as or larger than that of the curved surface of the curved glass 17.

The structure of the glass lifting device 21 according to the embodiment of the present invention has been described above.
The effect will be described.

As shown in FIG. 2, in the glass elevating / lowering device 21 of this embodiment, the main arm 23 and the sub arm 24 are curved along the curved surface of the glass. The gap w between them becomes narrower. Therefore, if the glass lifting device is used for the doors on both sides in the design of the automobile, the space in the room can be increased by (W−w) × 2. For example, if W-w is 5 mm, a width of 10 mm can be secured, and this space is particularly effective for a light vehicle.

Further, since the main arm 23 and the sub arm 24 are curved along the curved surface of the glass, the amount of variation in the size of the offset (see FIG. 6 of the conventional example) is small, and the main arm 23 and the sub arm are small. The deflection of 24 is also small. As a result, when the regulator handle is rotated when the glass is opened and closed, the rollers 5 and 14 sliding on the guide rail 2a of the bottom channel 2 and the roller 16 sliding on the guide rail 15a of the guide channel 15 can move smoothly.
Therefore, the operability of the regulator handle becomes smooth. Further, the glass 17 is not distorted and the glass 17 is not distorted.

Although the embodiment of the present invention has been described above, it is needless to say that the present invention is not limited to this and various modifications can be made based on the technical idea of the present invention.

For example, in the above-described embodiment, the arm portion 23a of the main arm 23 and the sub arm 24 are curved, but the curved portion is, for example, the main arm 2
3 from the pivot shaft 26 to the roller 5 and the sub arm 24
Only one of the first arm pieces 24a may be curved.
Further, although the main arm 23 and the like are curved with a constant radius of curvature, the curvature radius may be changed depending on the portion of the main arm 23 and the like. For curved glass,
It may be a quadratic curved surface such as a simple cylindrical curved surface, or spherical glass. When the glass is spherical glass, the bottom channel 2 may be further curved along the glass surface.

Further, although the above embodiment has been described by using the manual type regulator handle, the present invention can of course be applied to a power window. In this case, the load on the motor is reduced, so that the load on the motor is reduced.

[0022]

As described above, according to the present invention, when the regulator handle is turned to raise and lower the glass, the handle operation becomes smooth. In addition, since the main arm and the sub arm follow the glass shape, they can be arranged in a narrow space, and the interior of the vehicle can be widened accordingly. Further, the glass is not distorted by applying a biased force to the glass, and the appearance of the automobile is not spoiled.
