Description

[Detailed Description of the Invention] The present invention relates to a remote control device for a horizontal casement window for an automobile.

As shown in Figure 1, in a two-door car where the rear side window can be opened by rotating outward from the hinge at the front end, the driver sitting in the front seat can easily open the window while driving. Usually, a remote control device is installed near the driver's seat so that the rear side windows can be opened and closed.

The above-mentioned remote control device generally consists of a control lever and a wire connecting the control lever and the rear side window, and when the control lever is operated, the wire operates in the longitudinal direction to open and close the rear side window. There is.

However, when the rear side window is closed, the seal reaction force of the weather strip acts in the opening direction.
A large amount of force is required to maintain the closed state, and using only a remote control device using a control lever and wire has the disadvantage that the operating force becomes extremely large, especially when the seal reaction force is applied and the operating force is extremely large. Further, in order to prevent the window glass from opening due to external force when fully closed, a complicated mechanism such as a reverse rotation prevention mechanism is usually provided separately from the remote control device.

The purpose of the present invention is to provide a remote control device that has an extremely simple structure that eliminates the above-mentioned maximization of operating force during the closing operation, and also has a reversal prevention function that prevents operation in the opening direction due to external force. The present invention will be explained below with reference to the embodiments shown in FIGS. 2 to 4.

In Figures 2 to 4, 1 is a base fixed to a vehicle body member near the front seat, such as the floor, 2 is an operating lever rotatably attached to the base 1 via a shaft 21, and 3 is approximately L-shaped. The link 3 is rotatably attached to the base 1 at its corner portion by a shaft 31, and one end of the link 3 is connected to the elongated hole provided in the operating lever 2 via a pin 32. 22
and the other end has approximately L.
One end of the letter-shaped slide link 4 is rotatably coupled to a shaft 41.

A slide pin 5 is fixed to the other end of the slide link 4, and the slide pin 5 is slidably fitted into a guide groove 11 provided in the base 1.

The center of the shaft 31, which is the center of rotation of the link 3, is located on an extension of the center line of the guide groove 11.

One end of a wire (not shown) is connected to the slide pin 5, and the other end of the wire is connected to a rear side window.

In the above, when the operating lever 2 is rotated clockwise in FIG. 2, the link 3 whose one end is engaged with the elongated hole 22 of the operating lever 2 is rotated clockwise about the shaft 31, Slide link 4
rotates clockwise around the slide pin 5, and the slide pin 5 slides rearward (to the right in Figure 2) within the guide groove 11, opens the rear side window via the wire, and opens the rear side window as shown by the chain line in Figure 2. When the slide pin 5 reaches the rear end of the guide groove 11, the rear side window is fully opened.

Furthermore, when the operation lever 2 is rotated counterclockwise from the state shown by the chain line in FIG. 2, the link 3 is also rotated counterclockwise, and the slide link 4 is rotated counterclockwise about the slide pin 5. Slide pin 5
slides forward in the guide groove 11, and when the slide pin 5 reaches the front end of the guide groove 11, the rear side window is fully closed.

In the present invention, as shown in FIG. 5, when the slide pin 5 is in contact with the front end of the guide groove 11,
The distance A from the center a of the slide pin 5 to the pivot point b of the link 3 (i.e. the center point of the shaft 31), and the distance A from the pivot point b of the link 3 to the pivot point b of the slide link 4 (i.e. the center point of the shaft 41). The relationship between the length to center point c, that is, the effective length B of the link 3, and the length from a to c, that is, the effective length C of the slide link 4, is A+B>
C, and the structure is such that the slide pin 5 hits the front end of the guide groove 11 at a point slightly before the point c reaches the straight line connecting a and b, that is, the dead point Dp, and the rear side window is fully closed. .

When the operating lever 2 is further rotated in the closing direction, the portion between b and c of the link 3 is deflected by δ and further rotated counterclockwise, passing the dead point Dp and reaching the position shown by the chain line in FIG. At this position, the link 3 hits a stopper part 6 provided on the base 1, and further rotation is restrained, and point c reaches c' and is stopped.

If the rotation angle α from the fully closed position in front of the dead point Dp to the dead point Dp is made equal to the rotation angle α' from the time it crosses the dead point Dp until it is restrained by the stopper part 6, the link 3 No deflection remains, and the position of point a between c and c' does not change, so the rear side window remains fully closed.

When the rear side window is closed, during the period from just before fully closing to fully closing, that is, while the rear side window contacts and compresses the weather strip, and the sealing reaction force becomes strong, the wire for each unit rotation angle of the link 3 is Since the stroke in the pulling direction is extremely small, it is possible to easily overcome the seal reaction force and achieve full closure with a small operating force. Also link 3
By configuring the length from the center of rotation, that is, the length from the shaft 31 to the pin 32, as shown in the figure, to be larger than the length from the shaft 31 to the shaft 41, the lever ratio can further reduce the operating force. can.

When the fully closed operation is completed as shown by the chain line in FIG. 5, the load in the opening direction of the rear side window due to the seal reaction force acts in the direction of pressing the link 3 against the stopper part 6, so the link 3 is reversed and the rear side window opens. That never happens.

Furthermore, during the closing operation, the slide pin 5 is inserted into the guide groove 11.
After hitting the front end of the link 3, the link 3 is further flexed and rotated to complete the fully closed operation, which provides a sense of control and improves the reliability of the operation. .

As described above, according to the present invention, a remote control device with a boosting function during a fully closed operation and a function of maintaining a fully closed state can be achieved by a simple combination of a base, a simple operating lever, a link, and a slide link. In addition to improving operability by imparting moderation during the fully closed operation, this can bring about a great practical effect.
