Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window regulator that opens and closes a window glass by moving a wire.

[Conventional technology]

Generally, a wire type wind regulator is constructed as shown in FIG. In the figure, reference numeral 51 denotes a guide rail, which is attached along the vertical direction of the inner panel 71 of the automobile door 70. Further, a driving section having a rotating drum 52 is attached at a position spaced apart from the rail 51. On the other hand, the guide rail 51 is provided with wire guide members 53 and 54 at its upper and lower ends, and also supports a carrier plate 55 in a slidable manner. Note that a window glass 72 is attached to the carrier plate 55 via glass holders 73, 73. A wire 5 is connected between the drum 52 and each guide member 53, 54.
6, and both ends of the wire 56 are attached to the carrier plate 55 or drum 52 to form a triangular endless loop. Therefore, the wire 56 is sent in the forward and reverse directions by the rotation of the rotating drum 52, the carrier plate 55 moves up and down the guide rail 51, and the window glass 72 is raised and lowered.

By the way, such a wind regulator 5
0 is a unit part that is constructed by itself as an assembly. Therefore, if the wire 56 is left bare, its shape will not be determined, which will be extremely inconvenient to handle during storage, transportation, assembly, etc., and the wire 56 may come off from the drum 52 and guide members 53, 54, or may be damaged by other objects. There is a problem with the parts getting tangled.

Therefore, conventionally, the wire 56 between the drum 52 and the guide member 53 and the wire 56 between the drum 52 and the guide member 54 are covered with outer tubes 57 and 58 having a certain degree of rigidity to increase the overall rigidity. I tried to keep it from collapsing. Reference numeral 59 designates a tube holder that elastically holds both ends of each of the outer tubes 57 and 58 via a spring at one end, and fixes the other end to the drum 52 side or the guide rail 51 side.

[Problem that the invention seeks to solve]

However, the conventional wind regulator 50 has the following problems.

First, since the wind regulator 50 has a triangular shape when assembled, it occupies a large area, which is extremely disadvantageous in storage and transportation.

Second, although the outer tubes 57, 58, etc. have a certain degree of rigidity, they are unstable because they are spread throughout. Therefore, it is difficult to handle and has poor workability, such as poor assembly and assembling efficiency.

Thirdly, parts such as the outer tubes 57, 58, tube holder 59, etc. are required, which increases the number of assembly steps and increases costs.

[Means for solving problems]

The present invention aims to provide a new wind regulator for automobiles that eliminates the problems existing in the prior art described above, and is achieved by the window regulator shown below.

That is, the wind regulator 1 according to the present invention is particularly a wire-type wind regulator, in which, for example, a carrier plate 3 that is slidably supported on a guide rail 2 is divided in the sliding direction to form a pair of plates. Form half bodies 3a and 3b, and wire 4
Attach both ends to each plate half 3a and 3b.
Then, both ends of the wire 4 are wrapped on the guide rail 2 to reduce the loop of the wire 4, and while the wire 4 is kept under tension, one end 4a and the other end 4b of the wire 4, that is, each plate half 3a, are wrapped. 3
b to one end side and the other end side of the guide rail 2,
This makes it possible to bring the guide rail 2 and the drive section 6 of the wire 4 close to the shortest distance, thereby configuring the assembly unit Am in a state where it is not attached to an automobile door.

[Effect]

Next, the operation of the present invention will be explained.

In the assembled state of the wind regulator 1 according to the present invention, one end and the other end of the wire 4 are wrapped on the guide rail 2 to reduce the loop of the wire 4, so that the wire 4 becomes shorter in appearance. Therefore, the drive section 6 is drawn toward the guide rail 2, and the distance between the guide rail 2 and the drive section 6 becomes the shortest. Furthermore, since one end 4a and the other end 4b of the wire are fixed onto the guide rail 2 while the wire 4 is under tension, the overall shape is also fixed.

The stroke range of the carrier plate 3 that moves above can be set to the maximum usable stroke of the guide rail 2.

Next, the functions of the wind regulator 1 according to the present invention will be explained.

First, the wind regulator 1 in an assembled state looks like the one shown in FIG. 1. That is, the plate halves 3a and 3b of the carrier plate 3 are separated,
In particular, by positioning the plate half 3b toward the lower side of the guide rail 2, one end side and the other end side of the wire 4 can be wrapped over a wide range. Therefore, the apparent length of the wire 4 is shortened, and the rotating drum 5, that is, the driving section 6, is attracted to the guide rail 2, and the distance between them becomes the shortest distance. In this state, fixing springs 41 and 42 are respectively installed between the mounting hole 16 of the plate half 3a and the upper end of the guide rail 2, and between the mounting hole 21 of the plate half 3b and the lower end of the guide rail 2, and the wire 4 put into a state of tension. In addition to the springs 41 and 42, the means for fixing the plate halves 3a and 3b may be an elastic member such as a rubber band, or a rigid member such as a metal fitting having a hook. The assembly unit Am configured in this manner allows the wind regulator 1 to be downsized, occupying a significantly smaller space, and can be handled stably.
Parts such as tubes and holders that cover the parts are not required.

On the other hand, the wind regulator 1 when attached to an automobile door is as shown in FIG. first,
Remove the fixing springs 41 and 42 from the assembly unit Am shown in FIG. Then, the rotating drum 5 is separated from the guide rail 2, the wire 4 is expanded into a triangular endless loop, and the plate halves 3a and 3b are brought close to each other, so that the connecting parts 13 and 18, and 14 and 19 are overlapped.
Then, in this state, by tightening the lower ends of the glass holders 22, 24 connected to the window glass and the respective joints with bolts and nuts 23 as shown in Fig. 4, the carrier plate 3 can be assembled, and at the same time A window glass can be installed. Note that the guide rail 2 is connected to a bracket (not shown), and the drive unit 6 is connected to the base plate 3.
1, each is attached to the inner panel of an automobile door. Therefore, by rotating the rotary drum 5 by the drive unit 6, the carrier plate 3 can be moved up and down along the guide rail 2.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments. For example, although the case where the carrier plate is divided is shown, it may be divided in any way, and the carrier plate may not be divided, but one mounting part 3
4 may be removed from the carrier plate 3 and attached to the lower end side of the guide rail 2 in the same way as the plate half 3b. Other changes may be made in the detailed structure, shape, arrangement, quantity, material, etc., without departing from the spirit of the present invention.

〔Effect of the invention〕

In this manner, the wind regulator according to the present invention reduces the loop of the wire by wrapping one end of the wire on the guide rail and the other end of the wire, and wraps the one end of the wire and the other end of the wire on the guide rail with the wire under tension. Since one end and the other end of the wire are fixed to the end side, and the guide rail and the drive section are brought close to each other at the shortest distance, an assembly can be constructed, so that the following significant effects are obtained.

In the assembled state, there is no inner empty space (dead space) like in the past, so
The occupied area is significantly reduced. Therefore, storage and transportation of large quantities becomes possible.

Since the entire assembly can be made smaller, it can be handled easily and stably, and workability such as work efficiency can be improved.

Parts such as outer tubes and tube holders that cover the wires are no longer required, and the total number of parts can be significantly reduced. Therefore, it is possible to reduce assembly man-hours and costs.

If the carrier plate is divided according to the optimal embodiment, it can be easily attached to the door from the assembled state, and further improvement in workability can be achieved.
