Description

[Detailed Description of the Invention] [Industrial Application Field] 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 drive unit including 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. The drum 52 is connected to a wire 5 between each guide member 53 and 54.
6, and attach both ends of the wire 56 to the carrier plate 55 or the rotating drum 52,
Construct a triangular endless loop. Therefore, the wire 56 is sent in the forward and reverse directions by the rotation of the rotating drum 52, and the carrier plate 55 is moved along the guide rail 5.
1 is moved up and down, 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 where it gets tangled with the parts.

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, thereby increasing the overall rigidity. I was trying to keep it from collapsing. Note that 59... is a tube holder that elastically holds both ends of each of the outer tubes 57, 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 attempts 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 object of the present invention is to provide a new wind regulator for automobiles that eliminates the problems existing in the prior art described above, and is achieved by the wind regulator shown below.

That is, the wind regulator 1 according to the present invention is particularly a wire type wind regulator, in which the carrier plate 3, which is slidably supported on the guide rail 2, is divided in the sliding direction into a pair of plate halves. The bodies 3a, 3b are formed, and each plate half 3a, 3b is provided with a connecting portion 13, 14 and a connecting portion 18, 19, respectively. Then, the connecting portions of each plate half 3a and 3b, that is, 1
3 and 18, and 14 and 19 are stacked on top of each other so that they can be integrally fixed to the window glass side, and each end of the wire 4 is attached to the plate halves 3a and 3b located on the opposite side.

[Effect]

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

In the assembled state, the wind regulator 1 according to the present invention has two plate halves 3a and 3b.
can be separated from each other along the guide rail 2. Therefore, one end side and the other end side of the wire 4 are wrapped on the guide rail 2 to reduce the loop of the wire, and each plate half 3a, 3b is fixed to the one end side and the other end side of the guide rail 2, respectively. By doing so, the wire 4 can be made shorter in appearance while being tensed. Therefore, the drive section 6 including the guide rail 2 and the rotating drum 5 can be brought closer to the shortest distance, and the overall shape can also be fixed.

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, the plate half 3b is positioned below the guide rail 2, so that one end and the other end of the wire 4 are 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 way can miniaturize the wind regulator 1 and significantly reduce the space it occupies.It can also be handled stably, and parts such as tubes and holders that cover the wires 4 are not required. Become.

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, and the wire 4 is expanded into a triangular endless loop.
The plate halves 3a and 3b are brought close to each other, and the joint parts 13 and 18, and the joint parts 14 and 19 are overlapped. Then, in this state, the lower ends of the glass holders 22, 24 connected to the window glass and the respective joints may be tightened with bolts and nuts 23 as shown in FIG. Note that the guide rail 2 is connected to a bracket (not shown), and the drive unit 6 is connected to a base plate 31.
Each is attached to the inner panel of a car door. Therefore, the drum 5 is driven by the drive unit 6.
By rotating the carrier plate 3, 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, any known means such as bolt/nut tightening, riveting, etc. can be used to connect the connecting portions. Furthermore, the configuration, shape, arrangement, quantity, material, etc. of the joints and other details may be arbitrarily changed without departing from the gist of the present invention.

[Effect of idea]

In this way, the wind regulator according to the present invention divides the carrier plate in the sliding direction to form a pair of plate halves, and each plate half is provided with a joint part, and the joint part of each plate half is The wires can be stacked on top of each other and fixed together to the window glass side, and each end of the wire is attached to the plate half located on the opposite side, resulting in the following significant effects.

By dividing the carrier plate, the area occupied in the assembled state can be significantly reduced, making it possible to store and transport large quantities. In addition, by making the whole smaller, it is easier to handle and work efficiency can be improved, and parts such as an outer tube and tube holder that cover the wire can be eliminated, and assembly man-hours and costs can be reduced.

By dividing the carrier plate, it can be easily attached to the door from the assembled state, further improving work efficiency. Furthermore, the joint parts of each plate half and the window glass side can be integrally joined at the same time, making it easier to install the door from the assembled state. It is possible to achieve a reduction in assembly man-hours, a reduction in costs due to the elimination of separate members for joining each plate half, and an improvement in joint strength.
