Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wind regulator. More specifically, the present invention relates to a cable-driven wind regulator suitable for raising and lowering the window glasses of automobiles and buildings.

[Prior Art] A carrier plate as shown in FIGS. 5 and 6, for example, is used in a conventional cable-driven wind regulator. In the figure, 1 is a guide rail arranged vertically on a car door, 2 is a carrier plate, and 3 is a window glass.The window glass 3 is raised and lowered vertically by a cable 4 connected to the carrier plate 2. I'm starting to do that.
For example, slide shoes 5 are arranged in a staggered manner on the carrier plate 2, and slide in contact with a convex guide portion 6 formed in the longitudinal direction on the guide rail 1 to guide the lateral movement of the window glass 3. are doing.

Incidentally, the window glass of automobiles and buildings generally has a large surface area and is heavy. Therefore, in order to stabilize the guide in the lateral direction, especially in the case of automobile door window glass, in order to prevent it from tipping forward, the distance between the slide shoes 5 in the vertical direction (that is, along the longitudinal direction of the guide rail 1) is It is advantageous to have a large spacing. Therefore, all conventional carrier plates 2 have a fairly large dimension H in the vertical direction. For example, in the carrier plate shown in FIG. A shape having d is adopted.

[Problems to be Solved by the Invention] However, in recent years, there has been a tendency to increase the area of window glass in automobiles and buildings in order to improve design and visibility. Particularly in automobiles, there is a strong demand for increasing the vertical dimensions of door window glass.

However, in a cable-driven wind regulator using the conventional carrier plate 2,
Since the part d protruding from the lower edge of the window glass 3 creates a dead space within the door panel,
The length of the guide rail 1 is longer than the stroke required for raising and lowering the window glass 3, which limits the ability to increase the vertical dimensions of the window glass that can be used for a door of a certain size.

In view of the above circumstances, the present invention provides a wind regulator with a novel structure that can reduce the vertical dimension of the carrier plate while sufficiently guiding the lateral movement of the window glass.

[Means for Solving the Problems] The present invention is a window regulator that moves a window glass fixed to a carrier plate along a guide rail, and the window glass fixed to the carrier plate is moved along a guide rail. a fixed slide shoe, a movable slide shoe that is a substantially rod-shaped member extending along the longitudinal direction of the guide rail, protrudes from the carrier plate, and is provided with a shoe member near its protruding end; A compression coil spring is fitted in a region of the base of the slide show on the carrier plate side so that its axial direction is along the longitudinal direction of the movable slide show, and the movable slide show is connected to a guide rail. When the show member is extended in the direction away from the carrier plate along the longitudinal direction by the biasing force of the compression coil spring, and the show member abuts against the stopper, the spring is compressed and the show member is moved away from the carrier plate. A configuration that is shortened in the approaching direction is adopted.

[Function] In the present invention, since the movable slide shoe extends in the direction away from the carrier plate along the guide rail, the distance between the shoe member of the movable slide shoe and the fixed slide shoe is sufficiently large. The lateral movement of the window glass can be stabilized. Furthermore, when the carrier plate moves to the end and comes into contact with a stopper, the movable slide shoe is shortened along the guide rail in the direction toward the carrier plate, creating vertical dead space inside the door panel. I never tighten it.

In the carrier plate of the present invention, it is only necessary to attach the fixed slide shoe and the base of the movable slide shoe, and there is no need to increase the mounting interval between them in the vertical direction. Since the distance between the points can be made large, the vertical dimensions of the carrier plate can be made as small as possible.

[Example] Next, an example of the wind regulator of the present invention will be described.

FIG. 1 is a front view of the carrier plate and its surroundings in an embodiment of the present invention, FIG. 2 is a partial sectional view taken along the line X-X in FIG. 1, and FIG. 3 is a movable slide show shown in FIG. 1. FIG. 4 is a front view of the area around the carrier plate showing the movable slide shoe shown in FIG. 1 in a shortened state.

FIG. 1 shows the area around a carrier plate in a window regulator incorporated into a door panel of an automobile. In the figure, 1 is a guide rail, and 2 is a carrier plate 3, which is a window glass. The guide rail 1 is disposed within the door panel and extends in the vertical direction. As shown in FIG. 2, the guide rail 1 has a convex guide portion 6 formed by double bending on one side, and a bead with a bent side edge on the other side.

The carrier plate 2 is secured along the lower edge of the window pane 3 by suitable connecting means 7, such as two grommets or bolts. The carrier plate 2 has two guide shoes 8 and a guide rail 1 which are slidably contacted on both ends of the guide rail 1.
Two fixed slide shoes 9 that are primarily in sliding contact with the convex guide portion 6 are fixed, and a movable slide shoe 10, which will be described later, is further attached. The guide shoe 8 is an L-shaped member made of synthetic resin such as polyacetal, and both have the same cross-sectional shape. As shown in FIG. 2, their bases are fixed to the metal plate constituting the carrier plate 2 by insert molding or the like, and a small protrusion 8a is formed at the tip. The small protrusion 8a is in slight contact with the back surface of the guide rail 1, but the inner surface of the base portion 8b is spaced slightly from the side edge of the guide rail 1. This guide shoe 8 is mainly provided to perform a guiding function on the inner surface of the base portion 8b, and does not come into contact with it in normal use, or does not substantially guide it even if it does come into contact with it, but the window glass 3
When the window glass 3 is about to tilt significantly in the lateral direction, it comes into contact with the window glass 3 and acts as a guide to prevent the window glass 3 from tilting further. Note that the above-mentioned meaning of "secondary sliding contact" is also used in this sense.

The fixed slide shoe 9 is fixed to the upper and lower portions of the carrier plate 2, and is made of the same synthetic resin material as the guide shoe 8. Both have the same cross-sectional shape,
As shown in FIG. 2, a recess 9a is formed into which the convex guide portion 6 of the guide rail 1 slides, and its base is fixed to the carrier plate 2. The inner width of the recessed portion 9a is precisely finished so that it always contacts the convex guide portion 6 from both sides, and the lateral movement of the window glass 3 is always accurately guided. In this way, both end surfaces of the convex guide portion 6 and the sliding surface of the fixed slide shoe 9 are in close contact with each other, and rattling may occur when the window glass 3 is raised and lowered or due to external vibrations. There is no. Since the fixed slide shoe 9 is made of the above-mentioned synthetic resin, it has high sliding properties, its guiding action is smooth, and no maintenance is required.

The movable slide show 10 is constructed as follows. As shown in FIG. 3, the show member 11 is fixed to the lower end of a generally L-shaped arm 12, which is connected to an upper guide
The vertical movement is guided by a lower guide 14 and a lower guide 14. A spring receiving plate 15 is provided approximately at the center of the arm 12. On the other hand, a pre-compressed coil spring (hereinafter simply referred to as a spring) 16 is interposed between the spring receiving plate 15 and the lower surface of the upper guide 13.

The shoe member 11 is made of the same synthetic resin material as the fixed slide shoe 9, and has a concave portion 11 that slides into contact with the convex guide portion 6 of the guide rail 1.
A is formed. This recess 11a is formed to have the same shape and dimensions as the recess 9a of the fixed slide shoe 9, and cooperates with the fixed slide shoe 9 to perform a guiding action during normal use. The arm 12 is an L-shaped member when viewed from the front, and has an angled cross section with a bead 12a provided on its long side edge to increase rigidity. This arm 12 is guided by an upper guide 13 and a lower guide 14 and can slide up and down, and a retaining pin 17 is attached to the upper end. Both the upper guide 13 and the lower guide 14 are made of the same rigid resin as the guide shoe 8, and are fixed to the carrier plate 2 by insert molding or the like. The upper guide 13 is made up of a left side member 13a and a right side member 13b, which are adapted to clamp the bead 12a of the arm 12, and the left side member 13a is formed by an integrally formed arcuate portion 1.
3c elastically moves the arm 12 to the right side member 13.
It is pressed to the b side. Similarly to the upper guide 13, the lower guide 14 also has a left side member 14a and a right side member 14.
b, by which the bead 12a
The arc-shaped part 14
c is provided on the right side member 14b, thereby elastically pressing the arm 12 toward the left side member 14a. The spring 16 transmits its elastic force to the arm 12 via the spring receiving plate 15, and urges the shoe member 11 in a direction away from the carrier plate 2. The state of the show member 11 shown in FIG. 1 is such that the movable slide show 10 is extended. Further, since the spring 16 is deflected when an external force is applied, when the arm 12 comes into contact with a stopper 18 in the door panel, the arm 12 rises and the show member 1
1 is brought close to the carrier plate 2. Fourth
The figure shows such a situation.

As shown in FIG. 1, a cable 4 for lifting and lowering is attached to the carrier plate 2 in the vertical direction, and is connected to a winding drum (not shown) driven manually or by an electric motor. ), the carrier plate 2 is raised and lowered, and the window glass 3 is raised and lowered accordingly.

Next, the operation of this embodiment will be explained. window glass 3
When the movable slide shoe 10 is moved up and down inside the door panel by being pulled by the cable 4, the movable slide shoe 10 is extended as shown in FIG. . Therefore, in this state, the guiding action of the window glass 3 by the guide rail 1 is performed quite precisely and reliably, and in particular, the forward tilting (tendency to tilt in the direction of arrow P) of the automobile door window is reliably controlled. sell. On the other hand, when the window glass 3 is retracted into the door panel and reaches the lowest end, the arm 12 comes into contact with the stopper 18 inside the door panel and the carrier plate 2
It is shortened in the direction of approaching. Incidentally, after the window glass 3 is accommodated to the lowest end within the door panel, the forward tilting of the window glass 3 hardly becomes a problem.

In the embodiment shown in FIGS. 1 to 4, the shoe member 11 projects below the carrier plate 2, but it may also project upward. Further, two movable slide shoes may be provided, one projecting upwardly and the other movably projecting downwardly, or show members may be provided at the upper and lower ends of one movable slide show, respectively. In the latter case, it is preferable to arrange the spring so as to maintain the movable slide show at an intermediate height at all times.

As described above, in the wind regulator of the present invention, the vertical dimension around the carrier plate 2 can be reduced without impairing the guide function.

In this embodiment, the movable slide show 10
Since it moves telescopically as described above, it is possible to construct a guide mechanism by fixing the fixed slide shoe 9 to the carrier plate 2 and attaching the base of the movable slide shoe 10 to the side thereof, for example. Therefore, its vertical dimensions can be significantly reduced.

[Effects of the Invention] In the present invention, the vertical dimensions of the carrier plate can be reduced, so for example, the dead space in the door panel can be almost eliminated, or
Or it can be made extremely small. Therefore, it is possible to install window glass with larger vertical dimensions even though the door dimensions are the same.
