Abstract

PURPOSE: To reduce the extent of lost motion lying between a sliding member and a guide rail by molding this sliding member integrally with a carrier plate, and forming two projections different in height each, alternately. CONSTITUTION: A slide shoe 4 integrally outsert-molded with a carrier plate 3 is installed in a guide rail 2 free of vertical movements. A lower end of a windowpane 12 is clamped to the carrier plate 3, coupling an inner cable 5. This cable 5 makes up such a loop that it changes its direction at an idle pulley 6 on top of the guide rail 2, and further it changes its direction at an idle pulley 7 at a lower end by way of a driver 8 and it returns to the carrier plate 3 again. The slide shoe 4 forms both projections alternately into almost brush form, and the projection eliminates any lost motion lying between the slide shoe 4 and the guide rail 2. Likewise, another projection helps to perform a smooth sliding motion between the slide shoe 4 and the guide rail 2. Then, if such a load as being hard to support with the projection is added, it comes into contact with the guide rail 2, holding the carrier plate 3.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a window regulator of the present invention will be described with reference to the drawings. 1 is a side view showing an embodiment of the 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 a vertical sectional view of FIG.
FIG. 4 is a plan view showing an embodiment of the sliding member according to the present invention, and FIG. 5 is a side view showing another embodiment of the window regulator of the present invention.

FIG. 1 shows a state from the outside of the automobile, and 13 is a door panel of the automobile. Door panel 13
A main guide rail 2 is vertically attached to the inner wall of the. One slide shoe (sliding member) 4 is provided on the guide rail 2 so as to be vertically movable. The slide shoe 4 is formed integrally with the carrier plate 3, and the lower end of the window glass 12 is fixed to the carrier plate 3. Further, an inner cable 5 is connected to the carrier plate 3. Inner cable 5
Forms a loop in which the idle pulley 6 at the upper part of the guide rail 2 changes the direction, the drive device 8 is passed through, and the idle pulley 7 at the lower end changes the direction to return to the carrier plate 3. A sub guide rail 9 is arranged in front of the main guide rail 2 substantially in parallel with the main guide rail 2 and attached to a door panel 13. A window glass 12 is engaged with the sub guide rail 9 by a carrier plate 10 so as to be vertically movable. The sub guide rail 9 guides the front side of the window glass 12 and regulates the window glass 12 together with the main guide rail 2 in a two-point supported state.

The carrier plate 10 is substantially the same as the main carrier plate 3 except that it is not driven by an inner cable. Therefore, the main carrier plate 3 will be mainly described below. As shown in FIG. 2, the guide rail 2 has substantially the same sectional shape as the grooved steel with a lip,
The opening groove 14 is bent so as to extend according to the degree of bending of the window glass 12. Further, as shown in FIG. 3, a slide shoe 4, which is outsert-molded integrally with the carrier plate 3, is slidable with respect to the guide rail 2. The central portion of the lower end of the window glass 12 is connected to the elongated hole 15 of the carrier plate 3 by a fixing member such as a bolt 16 and a nut 17.

As shown in FIG. 4, in the slide shoe 4, the convex portions 18 and the convex portions 19 are formed alternately, that is, in a substantially brush shape. The convex portion 18 is for eliminating backlash between the slide shoe 4 and the guide rail 2, and the convex portion 19 is for smooth sliding between the slide shoe 4 and the guide rail 2. When a load that cannot support the protrusion 18 is applied, the protrusion 19 contacts the guide rail 2 and holds the carrier plate 3. 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.

The shape of the above-mentioned slide shoe 4 is not particularly limited as long as the play between the slide shoe 4 and the guide rail 2 can be eliminated and smooth sliding can be performed.

At least one slide shoe 4 is preferably provided on the guide rail. The slide shoe 11 is similarly formed.

Although the slide shoe 4 which slides on the side surface of the inner wall of the guide rail 2 has been described in the above embodiment, a slide shoe may be adopted as the main guide rail and a guide roller may be adopted as the sub guide rail. Both the slide shoe and the guide roller can form the sliding member according to the first aspect.

Next, another embodiment of the present invention will be described with reference to FIG. In the window regulator of FIG. 5, one carrier plate 33 guided by the main guide rail 30 is provided. A first sub guide rail 31 for guiding the sub carrier plate 34 attached to the rear end side of the window glass 12 is attached to the rear end side of the door panel. Further, a second sub guide rail 32 for guiding the slider 35 attached to the front end side of the window glass 12 is provided. In this product, the main guide rail 30 and the first sub guide rail 31 are not arranged in parallel, and when the window glass 12 descends, the front end of the window glass 12 is moved to avoid a tire house (not shown). It is arranged so as to incline downward. The sub guide rail plays a role of stabilizing the movement of the window glass 12.

Therefore, in this type of window regulator, the window glass 12 is provided on the main guide rail 30.
Only one slide shoe is provided to allow forward tilting. The sub-carrier plate 34 of the first sub-guide rail 31 and the slider 35 of the second sub-guide rail 32 serve as a carrier plate for the main guide rail 30.
It is installed at a position higher than the door 33 and at almost the same height as each other, and the window glass 12 is guided by the three parties.
