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, the rear side windows can be opened by rotating outward from the hinges at the front end. In order to open and close the rear side windows, a remote control device is usually installed near the driver's seat or in the middle between the driver's seat and the rear seat, or at the driver's seat and the rear seat.

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, and the wind flowing along the outer surface of the rear side window generates negative pressure that pulls the rear side window in the opening direction, making it difficult to maintain the closed state. requires a large amount of force, and when opened, the wind pressure from the vehicle is applied in the closing direction, so the rear side window can be fully closed, opened, and closed only with a remote control device using a control lever and wire.
It is impossible to maintain the closed state, and conventionally, the operating force suddenly increases due to the large seal reaction force that acts during the closing operation, and it is not possible to maintain the closed state.
Usually, a complicated mechanism such as a mechanism to prevent reverse rotation when fully opened is provided separately from the remote control device.

The present invention provides a remote control device with an extremely simple configuration that has a boosting function that acts in response to the seal reaction force generated during the closing operation as described above, and a reversal prevention function when fully closed and fully opened. This invention is described below in Figures 2 to 4.
The embodiment shown in the figure will be explained.

In Figures 2 to 4, 1 is a base fixed to a vehicle body member such as the floor near the front seat, 2 is an operating lever rotatably attached to the base 1 by a shaft 21, and 3 is a base end portion. The link is rotatably attached to the base 1 via a shaft 31. The operating lever 2 has an arc-shaped gear portion 2a centered on the shaft 21, and the link 3 has a gear portion 2a centered on the shaft 31. A gear portion 3a is formed on the circumference, and both gear portions 2a and 3
a are in a mutually engaged state.

Reference numeral 4 denotes a slide link rotatably attached to the tip of the link 3 by a shaft 41. A slide pin 5 is fixed to the slide link 4, and the slide pin 5 is connected to a guide groove 11 provided in the base 1. It is fitted in a slidable manner.

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 the rear side window.

In the above, when the operating lever 2 is rotated clockwise in FIG. 2, the link 3 is rotated counterclockwise in FIG. 2 due to the meshing of the gear parts 2a and 3a, and the slide link 4 is The slide pin 5 slides backward in the guide groove 11 while rotating downward at , opens the rear side window via the wire, and when the operating lever 2 is operated counterclockwise in FIG. 2, the link 3 is moved clockwise. rotate,
The slide link 4 slides forward, and when the slide pin 5 hits the front end of the guide groove 11, the rear side window is fully closed.

In this invention, as shown in FIG.
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 (that is, the center of the shaft 31), and the distance a
The relationship between the length from point e to the center c of the shaft 41, i.e., the effective length c of the slide link 4, and the length from point e to c, i.e., the effective length B of the link 3, is set so that A+B>C. The rear side window is configured so that the rear side window is fully closed when point c is on the straight line connecting points a and b, that is, slightly before reaching dead point Dp.

When the operating lever 2 is further rotated in the closing direction, the link 3 is deflected by δ and further rotated clockwise, passing the dead point Dp and reaching the stop formed on the base 1 at the position shown by the chain line in FIG. When it hits part 6, further rotation is restricted,
Point c reaches c' and stops.

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 abutted and restrained by the stopper part 6, the link No deflection remains at point 3, and the position of point a between c and c' does not change, so the rear side window remains fully closed.

During the closing operation of the rear side window mentioned above, 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 link 3 is Since the stroke in the pulling direction is extremely small, the boosting mechanism composed of link 3 and slide link 4 functions to respond to the seal reaction force, easily overcoming the seal reaction force with a minute operation force. It can be fully closed.

In addition, 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 1.
After hitting the end of the link 3, the link 3 is further bent and rotated to complete the fully closed operation, which gives a sense of moderation in the operation and improves the reliability of the operation. be.

The above description was made regarding the fully closed operation, but even when the fully opened operation is performed, as shown in FIG. Point c is located slightly in front of dead point Dp. From this state, link 3 is further bent and rotated in the closing direction, that is, counterclockwise. When point c crosses dead point Dp as shown by the chain line, the base 1, the fully open operation is completed.

When the fully open operation is completed, the load in the closing direction applied to the rear side window acts in the direction of pressing the link 3 against the stopper portion 7, and the link 3 does not reverse and rotate in the closing direction, and the fully open operation is performed. This provides a sense of moderation and improves the reliability of full-open operation.

Furthermore, if the link 3 is made of synthetic resin material,
The link 3 bends relatively easily, and no large load is applied to the shaft portion or the like.

During fully closed and fully opened operations, slide pin 5
The rotation angle α+α' from when the guide groove 11 hits the front and rear ends of the guide groove 11 until the fully closed and fully opened operations are completed.
and β+β' may be set in such a range that the operating angle of the operating lever 2 between them does not become too large, so that a sufficient reversal prevention function can be achieved and a sufficient sense of moderation can be provided.

As described above, according to the present invention, with an extremely simple configuration, it is possible to obtain a remote control device that has a boost function during a fully open operation and a function to fully maintain the fully closed and fully open states, as well as a fully closed and fully open state. It is possible to improve the operability by providing moderation when fully opened, and it can bring about a great practical effect.
