Abstract

PURPOSE: To unify the shape of a guide rail, and to decrease mandays for assembly by a method wherein a guide rail is arranged into a door panel, a carrier plate is extended at the lower end section of a window glass, an inner cable is connected to the carrier plate and a window regulator is formed of the guide rail, the carrier plate, the inner cable and a driving device operating the inner cable. CONSTITUTION: A guide rail 2 is fitted onto the inwall of a door panel 11 in the vertical direction. A carrier plate 3 is mounted on the guide rail 2 in a freely vertically movable manner. The carrier plate 3 is held by a holding member with plays in the thickness direction of a window glass 10 at the lower end section of the window glass 10. The window glass 10 is formed while obtaining elastic force in the thickness direction of the window glass 10. Consequently, the curved surface of the guide rail 2 need not be designed for each car kind. An inner cable 5 is bonded with the plate 3. As a result, the looseness of the window glass 10 is absorbed. The direction of the inner cable 5 is changed by pulleys 6, 7 for the rail 2, and formed in a loop. Accordingly, the shape of the guide rail can be unified.

A carrier plate 53 with an intervening plate attached is slidable along the guide rail 52 (Japanese Patent Laid-Open No. 62-862).
No. 82). This product has a problem that the number of parts is large and the number of assembling steps is large.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is not necessary to design the curved surface of the guide rail for each vehicle type. It is an object of the present invention to provide a window regulator that can be slid along a curved door.

[0004]

The window regulator of the present invention is (a) a window regulator for moving up and down a window glass while guiding both side edges of the window glass with glass run channels of the window frame, ) A guide rail vertically arranged in the door panel, and (c) a lower end portion of the window glass is held with play in a thickness direction thereof and is extended over substantially the entire lower end portion of the window glass, A carrier plate having an elastic force in the thickness direction of the window glass, (d) an inner cable for raising and lowering the window glass that is connected to the carrier plate and is stretched over idle pulleys at both ends of the guide rail, and (f) closed loop shape The constitutional feature is that the drive unit is configured to wind and rewind the inner cable connected to.

It is preferable to have a carrier plate which is slidable with the guide rail and is connected to a sliding member which absorbs the play in the widthwise direction of the window glass.

Further, it is preferable that both ends of the carrier plate have an elastic force in the thickness direction of the window glass in accordance with the curved locus of the window glass.

The carrier plate is preferably made of synthetic resin or metal having elasticity in the thickness direction of the window glass.

Further, it is preferable that the guide rail is formed in a linear shape or a curved shape.

[0009]

In the window regulator of the present invention, since the carrier plate has elastic force in the thickness direction of the window glass, it is not necessary to design the curved surface of the guide rail for each vehicle type, and the shape of the guide rail can be unified. it can. Further, since the sliding member is connected to the carrier plate, it is possible to absorb the play in the widthwise direction of the window glass. Since both ends of the carrier plate have elastic force in the thickness direction of the window glass, the guide rail can slide on the guide rail according to the curved path of the window glass.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a window regulator of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an embodiment of a window regulator of the present invention, FIG. 2 is a perspective view of a main part of the window regulator of FIG. 1, FIG. 3 is an explanatory view showing elastic deformation of a carrier plate according to the present invention, and FIG. FIG. 6 is a side view showing an operating state of the window regulator and the window glass of the present invention.

FIG. 1 shows a state from the outside of the automobile, and 11 is a door panel of the automobile. Door panel 11
A guide rail 2 is vertically attached to the inner wall of the. A single carrier plate 3 is provided on the guide rail 2 so as to be vertically movable. The carrier plate 3 is held by a holding member such as a bolt with a play in the lower end portion of the window glass 10 and its thickness direction, and extends over almost the entire lower end portion of the window glass 10,
The window glass 10 is formed to have elasticity in the thickness direction. Inner cable 5 on carrier plate 3
Are combined. The inner cable 5 forms a loop in which the direction is changed by the idle pulley 6 on the upper portion of the guide rail 2, passes through the drive device 8, is further changed by the idle pulley 7 at the lower end, and returns to the carrier plate 3 again.

As shown in FIG. 2, the guide rail 2 has substantially the same cross-sectional shape as the grooved steel with a lip and extends linearly regardless of the curvature of the window glass 10. In order to be slidable with the guide rails 2, a substantially brush-shaped slide shoe 4 and carrier plate 3 in which convex portions having different heights are alternately formed
And are connected by a bolt 13. The upper convex portion of the slide shoe 4 absorbs the play in the lateral direction of the window glass with the guide rail 2, and the lower convex portion is for smooth sliding with the guide rail 2. is there. Further, since the slide shoe 4 is formed in a substantially brush shape, the contact area with the guide rail 2 is small and has wear resistance. The material of the slide shoe 4 is nylon (P
A), a wear-resistant synthetic resin such as polyacetal (POM) is used.

As shown in FIG. 3, both ends of the carrier plate 3 are elastically deformed in the thickness direction of the window glass, that is, in the directions of arrows A and B according to the curved path of the window glass 10.

As the material of the carrier plate 3, a synthetic resin having excellent flexural elasticity such as polyacetal (POM), polycarbonate (PC) and polyarylate (PAR), or a metal material such as a shape memory alloy is used. The shape of the carrier plate 3 is not particularly limited as long as both ends thereof can be elastically deformed in the thickness direction of the window glass according to the curved path of the window glass.

FIG. 4 shows the operating states of the window regulator 1 and the window glass 10 of the present invention. The window glass 10 is curved in accordance with the curved door and draws a curved locus. The distance between the guide rail 2 and the window glass 10 is
The carrier plate 3 is elastically deformed in the thickness direction of the window glass 10 to be absorbed. In addition, although the guide rail 2 is formed in a linear shape in the present embodiment, it may be formed in a gentle curved shape. Therefore, it is not necessary to design the curved surface shape of the guide rail 2 for each vehicle type, and the guide rail 2 can be unified regardless of the vehicle type.

[0016]

According to the window regulator of the present invention, the shape of the guide rail can be unified and the number of assembling steps can be reduced.
