Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a window regulator for raising and lowering a windshield of an automobile, and more particularly to a wire-type window regulator.

Conventionally, in this type of window regulator, a wire-driven glass bracket slides along a guide rail fixed to a door panel for a door window or a vehicle body panel for a rear quarter window. This allows the window glass attached to the glass bracket to be raised and lowered. The wire is bent and guided in one direction by pulleys provided at both ends of the guide rail,
Both ends of the wire are connected to a drum rotatably supported by a base plate fixed to the door panel or the vehicle body panel, and the wire is driven by rotating the drum. There is. Incidentally, in order to maintain the wire in a tensioned state between the drum and the guide rail, an outer tube that covers the outer circumference of the wire is provided between a bracket to which the pulley is attached and a base plate that supports the drum. Therefore, one end of the outer tube needs to be fixed to the bracket, and the other end of the outer tube needs to be fixed to the base plate. Conventionally, the means for fixing the base plate and the outer tube is shown in FIG. Such a method was used. That is, in the case of the means shown in FIG. By inserting and loosely fitting the outer tube 5 therein, and fitting a coil spring between the locking ring 6 fixed to the end of the outer tube 5 and the collar 4, the outer tube 5 and the base plate 1 are connected. is now being fixed. In the figure, 7 is a wire. Therefore,
In the conventional wind regulator, when fixing the outer tube 5 to the base plate 1,
The collar 4 and the locking ring 6 are required, which increases the number of parts, and a process of caulking and fixing the locking ring 6 to the outer tube 5 is required, which significantly deteriorates the assembly workability, and the outer tube itself is not locked. There was a problem in that it required strength to withstand caulking fixation of the ring 6, which inevitably increased costs.

Purpose of the Invention In view of such conventional problems, the present invention provides a member that can be locked by simply fitting the end of the outer tube, and furthermore, by attaching this member to the base plate with one touch. An object of the present invention is to provide a wind regulator which greatly simplifies the workability of assembling an outer tube and a base plate.

Composition of the Invention In order to achieve the above object, the present invention provides a guide rail for slidably attaching a glass bracket fixed to a window glass, and a guide rail having an intermediate portion disposed along the length of the guide rail, A wire connected to the bracket, a drum around which both ends of this wire are connected and wound, a base plate that supports this drum, and a wire that is attached between this base plate and the guide rail and disposed between them. In the window regulator, the wire is attached to a side edge of the base plate. a mounting part that forms a bead part along the arrangement direction and a space part that follows the cross-sectional shape of the bead part; and a mounting part that extends integrally from the mounting part and engages and locks the outer tube end part. When assembling the outer tube to the base plate, the outer tube is fitted into the fitting portion of the tube holder, and the mounting portion of the tube holder is attached to the tube holder. This can be done by inserting it into the bead portion.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

That is, FIG. 2 shows a wind regulator 10 showing one embodiment of the present invention, and 11 is a guide rail attached to a door panel or a vehicle body panel (not shown). The guide rail 11 has a U-shaped cross section as shown in FIG. 3, and a glass bracket 13 fixed to the window glass 12 is slidably attached to the guide rail 11. Pulleys 14, 14a are rotatably attached to both ends of the guide rail 11, and a wire 15 is wound between these pulleys 14, 14a.
The wire 15 between a is located within the guide rail 11, and a portion of the wire 15 is connected to the glass bracket. And the pulley 1
Both ends of the wire 15 that has been passed around the wires 4 and 14a are passed around the drum 16 which is provided at a position apart from the guide rail 11, and the ends thereof are connected to the drum 16.
A wire 15 is connected and fixed to the outer periphery, and by rotating the drum 16, a wire 15 is moved, and the window glass 12 is raised and lowered together with the glass bracket 13. By the way, the drum 1
6 is rotatably supported by a base plate 17 attached to the door panel or vehicle body panel. A handle or a motor (not shown) is connected to the drum 16, and the drum 16 is rotated manually or automatically. 1
Outer tubes 8 and 18a are provided between the base plate 17 and the pulleys 14 and 14a, and cover the outer periphery of the wire 15 disposed between them. One end of the outer tube 18, 18a is fitted into a guide bracket 19, 19a mounted coaxially with the pulley 14, 14a, and the other end of the outer tube 18, 18a is fitted with a tube holder 20, 20a. It is designed to be attached to the base plate 17 via. That is, the base plate 17 is shown in FIGS.
As shown in the figure, a recess 17a is formed in the center for mounting the drum 16 and a stopper mechanism (not shown), and a hole 17b for mounting is formed in the periphery of the recess 17a. Bead portions 21 and 21a are formed on the side edges of the base plate 17 to attach the tube holders 20 and 20a. That is, the bead portions 21 and 21a are connected to the wire 15.
extends in the direction in which the drum 16 is disposed, that is, in the substantially tangential direction of the drum 16, and as shown in FIG. It is formed by this. On the other hand, as shown in FIGS. 7, 8, and 9, the tube holders 20, 20a have space portions 22 along the cross-sectional shapes of the bead portions 21, 21a.
The fitting portion 25 is configured to have a bottomed cylindrical shape and extend obliquely forward from the mounting portion 23 via a connecting portion 24. A bottom portion 25a of the fitting portion 25 is disposed on the mounting portion 23 side, and a cutout portion 26 is formed continuously from the entire length of the side wall of the fitting portion 25 and the bottom portion 25a to communicate inside and outside.

With the above configuration, the outer tubes 18, 18
One end of the outer tube a is attached to the guide bracket 19, 19a on the guide rail 11 side, and the other end of the outer tube 18, 18a is attached to the base plate 1.
When installing tube holder 2, first
Notch portion 26 formed in the fitting portion 25 of 0, 20a
The wire 15 is inserted into the fitting part 25 through the fitting part 25, and as shown in FIG.
After inserting the coil springs 28, 28a into the inner tubes from the opening side, the other ends of the outer tubes 18, 18a are inserted into the fitting portion 25 from the opening side. Next, this is done by inserting the space 22 formed in the attachment part 23 of the tube holder 20, 20a into the bead part 21, 21a of the base plate 17. In addition, the springs 28, 28a
has one end pressed against the bottom 25a of the fitting part 25,
The other end is contracted so as to be pressed against the end wall of the outer tube, and the outer tube 18, 18a is pressed toward the guide brackets 19, 19a, thereby tensioning the wire 15 within the outer tube 18, 18a. Therefore, in the wind regulator 10 of this embodiment, the outer tubes 18, 18a can be easily attached to the base plate 17 via the tube holders 20, 20a. By attaching only through 20a, the number of parts can be reduced. Note that the tube holder may not have the notch 26; in this case, the tube holder 20 may be attached to the inner wire 7 together with the outer tube in advance.

Effects of the Invention As explained above, in the wind regulator of the present invention, when attaching the outer tube to the base plate, the outer tube is fitted into the fitting portion of the tube holder, and the outer tube is fitted into the fitting portion of the tube holder. This is done by simply inserting the tube holder into the bead formed on the base plate, which greatly simplifies the assembly work and requires only the tube holder, which reduces the number of parts. In addition, since there is no need to attach the locking ring 6,
The outer tube 5 does not have to maintain the strength necessary for caulking the locking ring 6, and the outer tube material has an excellent effect of increasing the selection range of the outer tube material.
