Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire type opening / closing member apparatus for driving an opening / closing member such as a side glass of a vehicle door.

[0002]

2. Description of the Related Art A power window regulator as a wire-type opening / closing member driving device as described above is disclosed, for example, in Japanese Patent Application Laid-Open No. 9-25765. As shown in FIG. 8, the power window regulator includes a guide 50 provided so as to extend in the vertical direction of the side glass G, and a slider base 51 movably supported along the guide 50 in the extending direction. Prepare. Further, one ends of the wires 53a and 53b are wound around the drum 52 which is driven to rotate bidirectionally by a motor (not shown). The other end of the wire 53a is connected to the upper end of the slider base 51 via the upper end of the guide 50, and the other end of the wire 53b is connected to the lower end of the slider base 51 via the lower end of the guide 50.

[0003] When the motor rotates upward, the wire 53a connected to the slider base 51 via the upper end of the guide 50 is wound around the drum 52.
The wire 53 b connected to the slider base 51 via the lower end of the guide 50 is fed out of the drum 52.
As a result, the slider base 51 moves up along the guide 50, and the side glass G rises. On the other hand, when the motor rotates downward, the wire 53b
And the wire 53a is unwound from the drum 52. As a result, the slider base 51 descends along the guide 50, and the side glass G descends.

Here, the drum 52 and the slider base 51
If the wires 53a and 53b connecting the sliders 53a and 53b are slack, a state occurs in which the raising and lowering operation of the slider base 51 is delayed with respect to the rotating operation of the drum 52 during the raising operation or the lowering operation.

That is, after the raising operation, as shown in FIG. 10, the wire 53b drawn out of the drum 52 is slackened. From this state, when the drum 52 is rotated counterclockwise in order to lower the side glass G, the slider base 51 remains until the wire 53b is no longer loose.
Does not descend. Similarly, after the descent operation, as shown in FIG.
Is loosened. From this state, when the drum 52 is rotated clockwise to raise the side glass G, the slider base 51 does not move upward until the wire 53a is no longer loose.

Therefore, for example, when the driver operates the window switch for a short period of time to lower the closed side glass G slightly for ventilation or the like, the side glass G is turned on. The lowering operation is not performed at the same time as the operation, and the lowering operation is delayed with a delay according to the amount of extension of the wires 53a and 53b. Alternatively, when the open side glass G is operated by raising the window switch for a short period of time to limit the intrusion of wind, the side glass G does not move up at the same time as the switch operation, and the wires 53a, 53b extend. The ascending operation is delayed by a time corresponding to the amount. That is, when the position of the side glass G is slightly adjusted, it cannot be easily adjusted to a desired position.

In order to prevent such a situation, the wires 53a and 53b are assembled with a predetermined tension so that the wires 53a and 53b do not loosen between the drum 52 and the slider base 51. In the above-described power window regulator, as shown in FIG. 8, the other ends of the wires 53 a and 53 b are locked to a metal wire end case 54 provided on the slider base 51. As shown in FIG. 9, tension is applied to the wires 53a and 53b by a spring 55 provided in the wire end case 54, so that the wires 53a and 53b do not loosen.

[0008]

However, the wire 53
a, 53b may extend over a long period of time and become longer than the original length. Here, the above-mentioned Japanese Patent Application Laid-Open No. 9-25765
In the power window regulator disclosed in the publication, the extension of the wires 53a and 53b is absorbed by a spring 55 provided in a wire end case 54 of the slider base 51. For this reason, even if the wires 53a and 53b become longer than the initial length, the wires 53a and 53b do not loosen.

However, the tension applied to the wire 53 by the spring 55 that has absorbed the extension of the wires 53a and 53b is weakened. For this reason, when the drum 52 rotates, the spring 55 on the side wound by the drum 52 is elastically deformed, and the slider base 51 does not move until the wires 53a and 53b are wound to some extent. Therefore, even in this power window regulator,
As in the case where the wires 53a and 53b on the side wound by the drum 52 have slackness, when the position of the side glass G is slightly adjusted, there is a problem that the position cannot be easily adjusted to a desired position. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an opening / closing member drive capable of eliminating a delay in opening / closing operation due to extension of a wire for driving the opening / closing member.

As a result, the carrier plate 12 moves up and down. As a result, the side glass G fixed to the carrier plate 12 rises and the side window closes.

When the wire drum 17 is rotated counterclockwise by the rotation control of the motor 16, the other end of the second wire 15 is gradually wound up and the other end of the first wire 14 is gradually fed out. . Then, the carrier plate 12 descends in the elevating direction. As a result, the side glass G fixed to the carrier plate 12 descends and the side window opens.

Here, the other end 15 a of the second wire 15 is fixed and held by the ratchet mechanism 23 while being tensioned by the compression coil spring 22 of the wire holding portion 21.

Even if the second wire 15 is extended and becomes longer than the initial length within a long period of time, the wire holding portion 21 provided on the carrier plate 12 is kept in a state where the second wire 15 is not slackened. Because the other end 15a is fixedly held, the wire drum 17 is opened during the opening operation after the closing operation of the side glass G.
