[Industrial applications]

 The present invention relates to a cable operated automobile window regulator.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a power window capable of automatically opening and closing a window glass by using a drive source such as a motor in a window of an automobile, particularly a door window, has been widely used. For example, JP-A-62-82187. In the publication, a window glass is attached to a carrier plate that is vertically movable along a guide rail, and an ascending cable and a descending cable whose one ends are respectively locked to the carrier plate, and driving means such as a motor. It is a cable-driven window regulator that raises and lowers the window glass by reciprocating inside the guide rail by attaching the winding part of the spiral spring to the carrier plate and attaching both ends of the spiral spring to the lifting cable. Apply tension to the ascending cable and the descending cable by connecting them to the ends of the descending cable. One which is described.

[0003]

[Problems to be solved by the device]

 However, in the above conventional cable-driven window regulator, when the ascending cable and the descending cable reciprocate in the guide rail, the metallic guide rail and the cable come into contact with each other, which causes abnormal noise. Is likely to occur and rust may occur, and abnormal noise may occur due to friction between the ends of the spiral spring and the ends of the ascending cable and the descending cable. There was a problem.

An object of the present invention is to provide a window regulator for an automobile that prevents contact between a cable and a guide rail, suppresses generation of abnormal noise, and has a high rust preventive effect.

[0005]

[Means for Solving the Problems]

 The automobile window regulator of the present invention comprises a guide rail, a carrier plate that supports the window glass and moves up and down along the guide rail, and one end of each of which is locked to the carrier plate to reciprocate in the guide rail. In a cable-operated vehicle wind regulator equipped with a cable, a descending cable, and a driving means such as a motor, a cable that locks a cable tensioner spring extending between the cable and the guide rail to the guide rail. A tensioner spring locking part is provided, one end of the lifter is locked to the cable tensioner spring locking part, and one end of the cable tensioner spring is locked on it, and the other end of the lifter is a guide rail. It extends between the bottom of the guide rail and the cable. Ri prevents contact between the cable and the guide rail with a simple configuration, to suppress the generation of abnormal noise, it is possible to improve the corrosion protection.

【Example】

 Referring to FIG. 1, an embodiment of the present invention will be described. A guide rail 1 extending substantially vertically, an upper cable guide supporting bracket 2 connected and fixed to an upper end of a guide rail 1, and an upper cable guide supporting bracket 2 connected and fixed to a lower end thereof. A lower cable guide support bracket 3 and a motor mounting bracket 4 at an intermediate position. The motor mounting bracket 4 is provided with a motor 5 as a drive source and a drive drum 6 driven by the motor 5, and the wind glass ( A carrier plate 7 for supporting (not shown) is installed so as to be vertically movable along the guide rail 1, and one end of the ascending cable 8 and the descending cable 9 is connected to the carrier plate 7, respectively, and the ascending cable 8 is connected. Is the upper cable guide 10 disposed in the upper cable guide support bracket 2, and the descending cable 9 is the lower cable guide support. The other end is connected to the drive drum 6 via a lower cable guide 11 arranged in the racket 3, and a cable cover 12 for covering the ascending cable 8 between the drive drum 6 and the upper cable guide 10 is provided. A cable tensioner spring locking part 13 is provided upright at an appropriate place on the guide rail 1, one end is locked to this cable tensioner spring locking part 13, and the other end is locked to the cable cover 12 to connect the cable. A cable tensioner spring is stretched between the cover 12 and the guide rail 1, and a lifter 15 whose one end is locked to the cable tensioner spring locking portion 13 is provided, and the other end of the lifter 15 is raised to the guide rail 1. It is extended between the cable 8 and.

2 and 3, the cross section of the guide rail 1 is formed in a substantially concave shape having a flange projecting inward on the open side, and the guide rail 1 is divided into the upper cable guide support bracket 2 and the motor mounting bracket 4. A claw-shaped cable tensioner spring locking portion 13 is cut and raised toward the outside of the guide rail 1 at an appropriate position of the guide rail 1 between the two, and one end of the belt-shaped lifter 15 is connected to the cable tensioner spring engaging portion. A fitting portion 150 and a step portion 152 that fit into the stopper portion 13 are formed. The fitting portion 150 fits into the cable tensioner spring locking portion 13, and the end portion of the cable tensioner spring 14 is fitted over the fitting portion 150. The other end 152 of the lifter 15 is engaged with the stepped portion 152, and the other end 152 of the lifter 15 extends from the opening 130 formed by cutting and raising the cable tensioner spring engaging portion 13. It is inserted in the guide rail 1 and is extended between the guide rail 1 and the ascending cable 8 to surely prevent the two from contacting each other. Prevent misalignment.

[0008]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. One end of the lifter is locked on the cable tensioner spring locking part provided on the guide rail, and one end of the cable tensioner spring is locked on it, while the other end of the lifter is on the guide rail bottom part inside the guide rail. Since the cable is extended between the cables, it is possible to prevent contact between the cable and the guide rail with a simple structure, suppress the generation of abnormal noise, and improve the rust prevention effect.
