Description

[Detailed Description of the Invention] The present invention relates to a slider for guiding a window glass of a wind regulator for an automobile.

A wind regulator for an automobile consists of a wire and a drum around which both ends of the wire are wound and fixed.By rotating the drum manually or with an electric motor, one end of the wire is wound around the drum, and at the same time the other end is wound around the drum. A so-called wire whose end part is fed out to raise and lower the window glass connected to the wire. Drum type wind regulators have come into use in recent years.

Wire as above. A drum-type window regulator requires a window glass guide member consisting of a guide rail fixed to a panel of the door or vehicle body, and a slider attached near the lower edge of the window glass. The wire is fitted so as to be slidable, and the middle of the wire is connected to the slider, and the wire is actuated by rotating the drum as described above, and as the wire moves, the window glass is guided to the guide rail. It is designed to move up and down.

The guide rail generally has a substantially U-shaped cross section with vertical wall surfaces 1a and 1b on both sides, and the tip of one vertical wall surface 1b is bent laterally to guide the guide rail in the form of a flange, as shown by reference numeral 1 in FIG. A slider 2 having a shape formed with a surface 1c is used, and the slider 2 includes a base 21 attached directly or via a bracket near the lower end of the window glass, a guide piece 22 attached to the base 21, and upper and lower springs. shaped member 23,
24, 24, the guide piece 22 fits between the vertical wall surfaces 1a and 1b of the guide rail 1 to restrict movement of the window glass in the width direction, and the spring-like members 23, 24, 24 By sliding the flange-shaped guide surface 1c of the guide rail 1 between the front and back sides, displacement of the window glass in the thickness direction is regulated.

Conventionally, the spring-like members 23, 24, 24 are constructed as independent parts as shown in FIG. There are many problems, such as not only being disadvantageous in terms of cost and parts management, but also increasing the number of assembly steps.

The present invention attempts to solve the above-mentioned conventional problems with an extremely simple structure, and the present invention will be explained below with reference to the embodiments shown in FIGS. 2 and 3.

In the present invention, the slide piece 22, which is one of the components of the slider 2, has a wire insertion fixing part 22b and a fixing groove 2 for fitting into the base 21, as shown in FIG.
2c, the left and right standing wall surfaces 1a of the guide rail 1,
A spring-like piece 22d that comes into elastic contact with one side surface (hereinafter referred to as the surface) of the flange-shaped guide surface 1c of the guide rail 1 is made to protrude laterally from one side of the main body 22a that fits between the guide rail 1 and is integrally made of synthetic resin. As shown in FIG.
When the fixed combination main body 22a is fitted to the base 21 between the vertical wall surfaces 1a and 1b of the guide rail 1 by fitting the groove 22c of the groove 22c into the opening edge 21a of the base 21, it is configured integrally with the main body 22a. The spring-like piece 22d is configured to be in slidable elastic contact with the surface of the flange-like guide surface 1c of the guide rail 1.

The spring-like members 24, 24, which come into elastic contact with the back surface (hereinafter simply referred to as the back surface) of the one side surface of the flange-shaped guide surface 1c of the guide rail 1, are formed by cutting out a part of the base 21 as in the past. Support piece 21
The flange-shaped guide surface 1c is attached to the surface of the flange-shaped guide surface 1c by the spring-shaped pieces 22d and the spring-shaped members 24, which are attached to the slide pieces 22 and 21b, respectively, and are integral with the slide piece 22.
It is elastically clamped at three locations on the back surface to restrict displacement of the window glass in the thickness direction.

Also, the wire 4 is connected to the main body 22a of the slide piece 22.
The nipple 4a, which is fixed to the wire 4 by caulking or the like, is connected to the slide piece 22 by fitting it into the notch 22b' of the wire insertion fixing part 22b. The coupling structure between the slide piece and the slide piece is the same as the conventional one shown in the first figure.

In Figures 1 and 2, 3 is a bracket for attaching the guide rail 1 to a door panel or a vehicle body panel, and 5 is a guide tube for guiding both ends of the wire 4 from both ends of the guide rail 1 to a drum part (not shown). show.

According to the present invention configured as described above, the front side spring member 23 among the front side and back side spring members 23 and 24 that were conventionally necessary as slider components can be omitted, and the component The number of points can be reduced, and the number of man-hours for assembling the slider can be reduced accordingly, and costs can be significantly reduced, which can bring about a great practical effect.
