Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window regulator. More specifically, it is the window glass of automobiles and the window glass of buildings, etc.
This invention relates to a wire-driven window regulator suitable for raising and lowering while being guided by parallel sashes.

[Prior Art] A conventional wire-driven window regulator,
An example of a system for guiding the raising and lowering of window glass using parallel sashes is disclosed in Japanese Utility Model Application No. 61-20770.

The window regulator (B) will be explained based on FIGS. 5 and 6. In the figure, (50) is a door panel of a car, (51) is a sash, and (52) is a window glass. The window glass (52) is designed to move up and down.

The window regulator (B) includes a wire (53) connected in a closed loop, a drive device (54) that winds and unwinds the wire (53), and a first wire guide (55).
) and a second wire guide (5B). The first wire guide (55) is fixed approximately at the center of the door panel, and the second wire guide (56) is fixed to the door panel (50).
) is fixed at the lower end of the The wire (53) is connected to the first and second wire guides (55), (56) and the drive device (
The cables are arranged in a triangular shape between the window glass (
52) is attached to the wire (53) between the first and second wire guides (55) and (56) via a bracket (57). (58) is a conduit into which a wire is inserted, and is connected between the drive device (54) and the first wire guide (55) and between the drive device (54) and the second wire guide (5B).
are fixed between each. This conduit (58) not only maintains the wiring shape of the wire (53) but also has the role of receiving the tension applied to the wire (53) when the window glass (52) is raised and lowered using its own compressive force. , which is essential in order to effectively generate the lifting operation force. Note that this conduit (58) has some flexibility and is arranged in a straight V-shape or a somewhat bent V-shape depending on the shape of the door panel (50).

FIG. 6 shows the window regulator (B) during transportation and before being attached to the door panel (50). As already mentioned, the conduit (58) has some flexibility so that it can be bent somewhat into an arcuate shape. Since the wire (53) is inherently flexible, it can be bent freely, but in this conventional example, the wire (53) is pulled toward the drive device (54) and connected with the locking device (59) to secure the conduit. (58) is bent and the wire (53) is arranged so that it does not wobble.

[Problems to be Solved by the Invention] In the conventional example described above, the two conduits (58), which are wide open in a V-shape, must be bent, and therefore cannot be made sufficiently compact. Therefore, it occupies a large amount of space during transportation and is inconvenient to handle.

Furthermore, when assembling the window regulator to the door panel (50), it is generally necessary to insert it through gaps between various structures such as guard beams and reinforcing beams and attach it to the window frame. death .

However, in the conventional window regulator (B), if the wire (53) remains stretched in a triangular shape,
Since this is not possible, it is necessary to pass through various beams in a bent state as shown in FIG. 6, then remove the fasteners (59) and assemble it to the panel (50). However, even if you do that, the conventional window regulator (B) cannot change its V-shaped shape significantly, making it very difficult to work on it, and it is also complicated as it requires removing the locking tool (59). be.

In view of the above circumstances, it is an object of the present invention to provide a window regulator that is easy to transport and assemble.

[Means for Solving the Problems] The window regulator of the present invention is a window regulator for raising and lowering a window glass whose vertical movement is guided by (ω parallel sashes), (b) continuous with the sashes. (c) a first wire guide and a second wire guide to be fixed to the window frame along the up-and-down direction of the window pane at a distance commensurate with the up-and-down stroke;
a drive device for winding and unwinding the wires connected in a closed loop, and (d) two wires extending from the drive device.
The middle of the wire of the book is guided by the first wire guide so as to be bent in the same direction, and the end portion having a U-shape is guided by the second wire guide, (e ) A window glass is coupled to the wire between the first wire guide and the second wire guide, and a conduit into which the wire is inserted is fixed between the drive device and the first wire guide. A new configuration has been adopted.

[Function] In the present invention, the two wires extending from the drive device
It is guided by a wire guide and bent in the same direction. In other words, it has a dogleg shape as a whole. Therefore, when transporting it, it can be made very compact by folding it further into the dogleg shape. Also, the dogleg shape is a real shape even if it is bent in the middle, so when assembling it, it can be inserted into the narrow space of the door panel from one end to the other, making the assembly process much easier. becomes easier.

[Example] Next, one embodiment of the present invention will be described.

FIG. 1 is a front view of a window regulator (A) according to an embodiment of the present invention, and FIG. 2 is a front view of a window regulator (A) according to an embodiment of the present invention.
A) is a front view of a folded state; FIG. 3 is a front view of a window regulator according to another embodiment of the present invention;
The figure is a perspective view of a window regulator (A) attached to a door panel of an automobile.

In FIG. 1, (1) is a drive device, (2) is a first wire guide, (3) is a second wire guide, (4) is a wire, and (9 is a window glass).

The drive device (1) is for moving the wire (4) along the wiring route, for example, by winding two wires (4) in opposite directions around a built-in drum (not shown). , the wires (4) can be moved by connecting the respective terminals and rotating a handle 01).

Two wires (4) extend from the drive device (1). As the wire (4), usually several twisted wires such as metal wires or synthetic resin wires are used.

The wire (4) is bent back in a U-shape at the end where it is routed in a closed loop, and both ends are connected to the drive device (1).
It is connected to a drum, etc. Drive device (1) and first
Conduits (12a) and (12b) for guiding the wire (4) are fixed between the wire guide (2) and the wire guide (2). These conduits (12a) and (12b) are conduits for pull control cables (Bowden cables), and are usually metal spiral tubes whose inner and outer surfaces are coated with a synthetic resin layer. Therefore, such conduits (12a), (12b
) has some flexibility and can be bent to match the shape of the door panel, converting the compressive force applied to the wire (4) into pushing force to smoothly raise and lower the window glass (5). generate force.

First wire guide (2) and second wire guide (3)
Any type of wire can be used as long as it maintains the wiring shape of the wire (4) and guides the change of direction of the wire (4). Generally, it is preferable to use a press-molded metal plate as the strength member, to make the portion in sliding contact with the wire (4) made of synthetic resin, and to attach that portion by insert molding or other suitable method. The first wire guide (2) is composed of a guide roller 04 made of synthetic resin that is pivotally supported by a metal plate (2) and a part of a conduit. That is, the wire (4) on the conduit (12a) side is passed around a guide roller 0Φ made of synthetic resin, so that the direction of movement cannot be changed. A portion of the conduit (12b) is fixed to the plate 0 by being bent by two clamps. The wire (4) within the conduit (12b) is guided by the curved section of the conduit (12b), and its direction of movement is changed.

The second wire guide (3) is a metal bracket/Oe
3 is used, with a half-moon-shaped synthetic resin guide plate attached to the side.

The wire (4) is looped around this guide plate 07) and folded back into a U-shape.

Due to the first wire guide (21 and second wire guide (3)), two wires (4) extending from the drive device (1) extend in parallel, and the first wire guide (21) and the second wire guide (3) extend in parallel.
2) is bent in the same direction, and the second wire guide (3)
It has reached this point. Therefore, the window regulator (A) of this embodiment is bent into a dogleg shape as a whole.

A window glass (5) is attached to one of the two wires (4) between the first wire guide (2) and the second wire guide (3) using a connector (2v). The connector (21) may be of any type as long as it can reliably connect the window glass (5) to the wire (4). The window glass (5) is guided on the left and right sides by parallel sashes (6), so the connecting tool (2) is used.
1) is also very small, and it is sufficient to support one point of the window glass (5). The other wire (4), to which no window glass (5) is attached, may be guided by a conduit. In that case, the conduit can be easily installed by extending the conduit (12b) to the second wire guide (3). However, as shown in FIG. 3, the other wire (4) may not be provided with a conduit. In that case, it is preferable that the conduit (12b) is cut off from the part bent and fixed on the first wire guide (21).

The window regulator of the present invention is used to raise and lower a windowpane whose raising and lowering movements are guided by parallel sashes. As an example of such use, FIG. 4 shows a window regulator (A) attached to a door panel (7) of an automobile. The upper half of the illustrated door panel (sword) is a window, and parallel sashes (6) are provided on both sides. The window glass (5) is guided by the sashes (6) and raised and lowered. In the lower half of the door spring (7), there is a window frame (8) that is continuous with the sash (6).
) is provided, which includes a first wire guide (2)
and a second wire guide (3) are fixed.

The first wire guide ('2I) and the second wire guide (3) are fixed at a distance commensurate with the vertical stroke of the window glass (5) along the vertical direction of the window glass (5).Drive The device (1) is fixed to the inner panel of the door with bolts or the like.

In such a door panel (7), the window glass (5
) is guided by Satsushi (6) for left and right movement, so
There is no need for the window regulator (A) to restrict the left and right movement of the window glass (S). Therefore, the window regulator (A) only needs to be a mechanism that can apply the lifting force to move the window glass (5) up and down. Therefore, in the window regulator (A) of the present invention, the connector (21
There is no need for a guide rail for regulating the movement of the wire (4) in the left and right direction at the part where wire (4) is attached. In other words, it is sufficient to suspend the wire (4) between the first wire guide ('2I) and the second wire guide (3). (2), there are conduits (12a) and (12
b) is provided, the tension acting on the wire (4) is received by its compression and effectively generates a lifting operation force. Therefore said conduits (12a), (12b)
It is not necessary to arrange it in a straight line, but it can also be arranged in a curved shape.Therefore, the mounting position of the drive device (1) can be freely moved within a considerable range horizontally and vertically. The degree of freedom is extremely high.

Since FIG. 1 shows the window regulator (A) in the installed state shown in FIG. 4, its movement will be explained based on FIG. Handle 0+) to arrow (xl)
When turned in the direction, the wire (4) moves in the direction of the arrow (X4),
The window glass (5) rises.

When the handle (old) is turned in the direction of the arrow (Yl), the wire (4) moves in the direction of the arrow (Y4) and the window glass (5) is lowered. In this way, the window glass (5) can be raised and lowered in the same manner as in the known wire-driven window regulator.

As already mentioned, the window regulator (A) of the present invention has a dogleg shape as a whole. Moreover, a rigid guide rail is not used between the first wire guide (21) and the second wire guide (3),
Only a highly flexible wire (4) is routed. One of the two wires (4) is connected to the conduit (12b).
), it has enough flexibility to bend it, so it can be bent quite freely.

FIG. 2 shows a state in which the window regulator (A) of the present invention is bent from a doglegged state to a substantially parallel state. In the present invention, there is also a certain degree of flexibility between the drive device (1) and the first wire guide (2), and there is considerable flexibility between the first wire guide ('2J) and the second wire guide (3). Therefore, it is easy to bend the first wire guide (2) as a base point to reduce the space occupied.

In order to maintain this bent shape, a support rod may be inserted between the first wire guide (2) and the second wire guide (3). In this case, even if the artificial bending force is released, the folded state will be maintained, which is convenient for transportation. Note that the support rod may have any form as long as it can maintain the bent posture. Also, instead of the support rod, a vibrator that performs the same function may be used. When using a vibrator, use the 1st and 2nd wire guides (
The wire (4) may be interposed between 2) and (3), or the wire (4) may be inserted therein. In that case, the vibrator may be split vertically to facilitate attachment and detachment.

Connect the window regulator (A) to the door spring (7)
When installing the support rod, the support rod is first removed. Then, the window regulator (A) will be restored to its dogleg shape, but as mentioned above, each part has flexibility, so the inner angle of the dogleg shape can be widened from its natural state. You can also narrow it down. In that case, compared to the triangular shape of the conventional window regulator (B), the shape can be changed much more freely, and even if it is bent in the middle, it is generally a genuine shape. It is easy to insert the door panel (sword) into a narrow space, and the installation can be done efficiently by changing the posture according to the complicated shape inside the door panel (7). It also has rigidity, making it easy to handle, especially the first
It is also easy to attach the second wire guides (2) and (3) to the window frame.

[Effects of the Invention] The window regulator of the present invention can reduce the space it occupies during transportation, and can be easily assembled to a door panel.
