Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an opening/closing device for a ventilator window for an automobile.

As shown in FIG. 1, some automobiles are equipped with a ventilator window 4 on the rear side of a vehicle body 1, and the ventilator window 4 can be opened to ventilate the interior of the vehicle.

The opening/closing operation of the ventilator window 4 can be performed either by gripping a catch bundle provided directly on the windshield or by rotating a regulator bundle of an opening/closing device attached to the vehicle body panel.

Incidentally, the opening/closing device is usually one that uses a worm and a worm wheel.

In this system, a worm wheel is provided on the drive shaft connected to the lower pivot that supports the ventilator window so that it can be opened and closed, and a worm is provided on the regulator bundle shaft that intersects with the drive shaft. The rotation of the shaft is transmitted to the pivot to open and close the ventilator window.

However, such a conventional configuration causes problems as described below.

(a) Due to the sloped shape of the side of the vehicle, it is often impossible to orthogonally connect the drive shaft connected to the lower pivot of the ventilator window with the regulator shaft.
As a result, the worm and the worm wheel do not mesh properly, which not only prevents smooth opening and closing operations but also makes bundle operation difficult.

In addition, there is a limit to the angle at which they can intersect, and they cannot be used in vehicles where the side of the vehicle body has a large inclination.

(b) The pivot position of the ventilator window restricts the regulator shaft and therefore the regulator bundle position.

That is, the distance between the drive shaft and the regulator shaft is determined only by the diameters of the worm and the worm wheel, and therefore there is no freedom in layout, and the regulator bundle may have to be placed in a position that is difficult to operate.

In view of these conventional drawbacks, the present invention aims to provide an opening/closing device that has no restrictions on the intersection angle between the drive shaft and the regulator shaft or the setting position of the regulator bundle, and that can perform opening/closing operations smoothly with light operating force. It is something.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 2, the ventilator window 4 is attached to the vehicle body opening 2 via upper and lower pivots 5 and 6 so as to be openable and closable.

Reference numeral 7 indicates an opening/closing device that is connected to the lower pivot 6 and opens and closes the ventilator window 4 by rotating the lower pivot 6, 8 is a base plate fixed to the back surface of the vehicle body inner panel 3, and 9 is a regulator shaft. As shown in FIG. 3, the regulator shaft 9 is rotatably mounted on a bearing boss 10 formed on the base plate 8, and a drive pinion 11 is fixed to one end thereof.

A sector gear 12 is rotatably mounted on one side of the base plate 8 with a pin 13 and meshes with the drive pinion 11, and has an arm portion 14 extending from the upper edge of the sector gear.

Reference numeral 15 denotes an actuation rod whose one end is pivotally connected to the arm portion 14 with a pin 16, and the other end is connected to an actuation arm 21, which will be described later.

A bracket 17 is provided on the side of the base plate 8 on which the drive pinion 11 is disposed.
The drive shaft 18 is rotatably erected and supported.

This drive shaft 18 is connected to the end of the lower pivot 6 of the ventilator window 4 via a pin 20 through a socket part 19 at the upper end, and an operating arm 21 is integrally fixed to the lower part of the socket part 19. The other end of the actuating rod 15 is connected to the free end of the actuating arm.

Here, in particular, the drive shaft through hole 17a of the bracket 17 mentioned above is formed into a slightly elongated hole in the vehicle width direction, as shown in FIGS. 3 and 4, so that the position of the drive shaft 18 in the vehicle width direction can be freely adjusted. , it is possible to automatically correct misalignment between the lower pivot 6 and the drive shaft 18 in the vehicle width direction due to the sloped shape of the vehicle body side.

Further, a bushing 25 is disposed on the drive shaft 18 directly below the operating arm 21 to ensure smooth rotation of the drive shaft 18.

On the other hand, when the above-mentioned opening/closing device 7 is used for manual operation, a serration engagement portion 22 is formed on the other end of the regulator shaft 9 as shown in FIG. The regulator bundle 23 is inserted into the engaging portion 22 to protrude toward the inside of the vehicle, and the regulator bundle 23 is engaged and fixed to the engaging portion 22.

Further, when driving by a motor, the other end of the regulator shaft 9 may be organically coupled to a deceleration mechanism (not shown) that decelerates the rotation of the motor.

Next, the operation of the embodiment device having the above configuration will be explained.

When the regulator shaft 9 and the drive pinion 11 integrated therewith are rotated by operating the regulator bundle 23, the sector gear 12 meshed with the pinion 11 swings upward or downward about the pin 13, and the operating rod 1
5 in the direction of the arrow in Fig. 3.

As a result, the drive shaft 1 is
8 rotates, and this rotation is transmitted to the lower pivot 6 to open and close the ventilator window 4.

Here, even if there is a deviation in the vehicle width direction between the lower pivot 6 and the drive shaft 18 due to the inclined shape of the vehicle body side, the drive shaft 18 can be displaced in the vehicle width direction by the long hole 17a of the bracket 17. Since the position can be adjusted automatically, the operating force does not become heavy and the smoothness of opening and closing of the ventilator window 4 is not impaired.

As described above, according to the present invention, the rotation of the regulator shaft is converted into the linear movement of the actuating rod, and then into the rotational movement of the drive shaft. Unlike a system that directly transmits rotation to the drive shaft, the regulator shaft and drive shaft do not need to be orthogonal to each other, and there are no restrictions on the intersection angle between these two shafts, so it can be used even when there is a large angle of inclination on the side of the vehicle. In addition, since the drive pinion and the sector gear mesh on the same plane of the base plate, the meshing form is not influenced in any way by the intersection angle between the regulator shaft and the drive shaft. The shaft is arranged so that its position can be freely adjusted in the vehicle width direction, and the deviation in the vehicle width direction relative to the lower pivot of the ventilator window can be automatically corrected, so the operating force is light and the ventilator window can be opened and closed smoothly.
