Regarding Killwind Regierenita, it can be treated as a set.

Raise and lower the window glass by rotating and reciprocating the lever etc.
Due to the recent demand for lighter vehicles, window regulators that are driven by motors have been switched from gear-arm type to wire-driven type. Since such a wire-driven window regulator can be relatively easily separated from the driving device and the driven device, it also has the advantage that each device can be installed at a position suitable for its function. An example of such a window regulator is the one disclosed in Japanese Utility Model Application Laid-Open No. 55105576. This device consists of a drive device and a driven device, and the driven device consists of a bracket to which the window glass is fixed, and one guide rail installed in an approximately vertical direction that can slidably guide the bracket. Two wires are engaged with planar nuts and extend in the vertical direction of the guide rail. The drive device includes a pulley formed by forcing one end of each of the two wires in opposite directions and engaging the leading end of each, a casing that rotatably supports the pulley, and a lever that is engaged with the pulley. It consists of A driven device and a driving device having such a basic configuration are installed at an appropriate location such as a car door, and the wire is routed between them in a loop to transmit power from the driving device to the driven device. are doing. That is, by rotating the lever, one end of the wire is wound around the pulley and the other end is unwound from the pulley, the loop of wire is slid in one direction, and the bracket that is engaged with a portion of the loop is moved onto the guide rail. The nitrous glass is moved up and down by sliding along the sides. Such a window regulator has the advantage that the driven device and the driving device can be easily installed at appropriate positions relative to the door, etc., but on the other hand,
The drawback is that it cannot be handled as a single window regulator. In other words, workers must mount multiple pieces of equipment accurately.
Furthermore, after installing each device, it is necessary to route the wires and adjust the length of the wires so as to apply appropriate tension to the wires, which requires a great deal of effort. Moreover, regular window regulators come with a balance spring mechanism that balances the weight of the glass and makes operation easier, as well as a wire stretch absorbing mechanism (described later), but the installation and wiring of these mechanisms is difficult. If this is included, the above-mentioned attachment work will require even more labor.

Further, in these window regulators, the wires stretched between each device need to be routed in a straight line in order to transmit power. In other words, cable wires guided by conduits etc.
If the wire is not stretched in a straight line, it cannot transmit power. Therefore, each device has the restriction that power must be distributed two-dimensionally in a two-dimensional manner, and also has the disadvantage that the installation space must be extremely large.

On the other hand, wires made of stranded metal wires have the characteristic that they elongate when tension is applied, especially at the beginning of the wire's use.

For this reason, conventional window regulators are also equipped with a tension pulley or Vulteau nut type wire elongation absorption mechanism, but the operator of these wire elongation absorption mechanisms must constantly check the extent of the elongation or slack. There are disadvantages in that the elongation absorber*1 must be operated as necessary, and furthermore, adjustment is troublesome, and adjustment is extremely difficult depending on the mounting position of the window regulator.

Recently, in order to eliminate the drawback of tilting, two pulleys are rotatably provided on the same axis, wires are run in opposite directions to each pulley, and latches are installed on the inner surfaces of these pulleys in opposite directions. y) The teeth are arranged, and the shaft is provided with claws that can engage with these Noracheck F teeth,
When rotating the shaft in either direction, only one ratchet tooth engages the pawl and the wire elongates 1. A transmission device capable of absorbing vibration has been proposed (Japanese Patent Publication No. 54-31).
(Refer to Publication No. 143) 0 However, in this case, the force is concentrated on the claws during driving, so there is a problem in terms of strength if left as is. Therefore, it is necessary to increase the number of pawls that are engaged with each tooth, which increases the number of parts and complicates assembly.

Furthermore, since the two units are coaxially arranged, the device itself requires a considerable thickness, and there is a space restriction in housing it in a door panel of an automobile or the like. Furthermore, there is an increasing demand for thinner connections between power windows and motors.

Further, in the window regulator disclosed in the above-mentioned Japanese Utility Model Publication No. 55-103376, the main part of the driving device or the driven device is arranged below the door, etc., and the wire is routed below the door. . However, these devices have drawbacks such as rainwater adhering to the wires and devices for a long time, which can cause the wires and devices to rust, or freeze in winter or in cold regions, making the device inoperable.

Therefore, the inventors of the present invention have eliminated the drawback of tilting, and have made it possible to handle the driving device and the driven device as one compact unit even though they are substantially separate, thus requiring less space for handling. In addition, we have conducted extensive research to provide a windray 4-rater that can automatically absorb the elongation of the wire by operating a thinly constructed drive device and prevent rust from occurring. As a result of repeated efforts, the present invention was completed.

Accordingly, the present invention provides a window regulator comprising a driven device for raising and lowering nitrous glass, and a driving device connected to the driven device so as to transmit power by wire,
At least one of the driven devices is provided substantially vertically.

The gist of the present invention is to provide a window regulator which is locked to the twenty-first locking hole.

Next, one embodiment of the window regulator of the present invention will be described with reference to the drawings.

As shown in Figure 11m1, the window regulator of the present invention has a driving device (1) and a driven device (2) connected by two parallel flexible conduits (8).

The driven device (2) includes one guide rail (4) provided substantially in the vertical direction, and a bracket (6) slidably provided on the guide rail (4) to which the window glass (5) can be fixed. is the basic configuration, and further includes guide rails (4
) is provided with a guide member (7) at the lower end and a cable guide (8) at the upper end to slidably guide the wire (9) and the ring. The wires (9) and (g) have locking members (9m) and (10m) fixed to their tips.
a) is locked to the bracket (6) by hooking it to the locking groove (6&) provided in the bracket (6), and extends downward and upward, respectively.

A wire (9) extending downward engages with the guide member (7) and is slidably guided so as to change direction upward;
The wires (Q) and (7) extend in parallel with the wire sakaki extending upward and reach the knurple guide (8).The wires (Q) and (7) are slidable within the cable guide (8) so as to change their directions at approximately right angles. and then the cable guide (8)
The two flexible conduits (8), one end of which is fixed to the casing aυ of the drive device and the other end fixed to the casing aυ of the drive device, are slidably guided in parallel to reach the drive device (1). In the figure, (11m) and (111)) are the main body and lid of the casing (B), respectively, and both constitute a ring-shaped casing (B). (b) is the casing (

Furthermore, in the embodiment shown in FIG. 2, a lever mounting portion (12o) is formed at the shaft end (12&) of the first shaft (b), into which the lever (b) is fitted.

In addition, the first shaft (b), etc., are driven by a motor (not shown).Furthermore, in this embodiment, in order to avoid being affected by external force when the lever operation is stopped, the first shaft (b), etc. In order to actively apply a constant tension to the wire being rotated, a washer spring Sakaki is inserted into the gap between the casing cover (ITh) and the pulley, and a brake is applied to the rotation of the pulley. (
(b) A hollow g-ring is bored in the casing lid (111).
) is provided with a protruding boss ■, and the inner wall (21&) of ) is provided in the hollow part.
A thin coiled spring member whose both ends are fixed to the outer periphery (22a) of the boss and the boss is accommodated in the hollow portion (2). Wire (9) due to the weight of this hoai hemp glass
Since the load on the driven device increases with respect to the winding direction of ( ), it is preferable to orient the spiral spring (■) so as to lighten the load. By doing this, the wire can be wound smoothly due to the weight of the window glass, and conversely, when the window glass is raised, the repulsive force of the spring allows the wire to be wound lightly, making it easy to operate with less effort. .

The operation of the window regulator configured as above will be explained below. By rotating the lever (B) in the direction (4), the wire (9) is wound around the first pulley (B) and the window glass is lowered. j12 gear (
(to) in the extension) direction, but the ratchet teeth (16
m+) and (17b) are in the sliding direction, so no torque is transmitted to the second pulley.

Therefore, the second pulley (B) is rotated only by the force with which the wire is pulled out, that is, the tension of the wire α. At that time, if the wire (6) is stretched and the tension of the wire is relaxed, the lever (b), the first shaft (b), the first pulley (b), and the first gear (b) and the second gear (B) rotates, but the second pulley (B) does not rotate due to the braking force of the washer spring and the thin coil spring ■, and the tension of the wires (9) and (G) causes these brakes to rotate. It can only rotate when it counteracts the force. By lowering the window glass in this way, the stretch of the wire is automatically absorbed and the tension is restored.

When the lever (B) is rotated in the (0) direction, the first shaft (B), first pulley (B), and first gear are also rotated in the (0) direction, and the second gear (b) is rotated in the φ) direction, and the pulley (b) of ll12 is also rotated in the (9) direction in synchronization with the first pulley via the ratchet teeth (16b) and (17b). Therefore, the wire is wound around the second pulley (B), and the wire (9) is sent out from the first pulley (B). In this case, since the wire is not pulled out from the first pulley (b) due to the tension of the wire,
Wire elongation is not absorbed.

It goes without saying that a lever attachment W6- may be formed at the shaft end of the second shaft (as shown by the two-dot chain line in FIG. 111), and the lever may be fixed to the attachment portion.

In Fig. 5, a second gear Sakaki is fitted on the outer periphery of the second shaft so that it can rotate and move slightly in the axial direction, and a pulley (B) of 1s2 is fixed. . Although the lever is fixed to the lever attachment portion at the end of the second shaft (B), it may be attached to the first shaft. The action of the Oku-koji example configured in this way is that by rotating the lever/Mackerel and rotating the shaft of 11!2 in the (2) direction, the wire ■ is wound around the second pulley (B). The driven device is actuated and the wire (.) is moved to the first pulley (
b). At this time, the elongation of the wire is absorbed. Conversely, when rotating the lever ■ in the (to) direction, the ratchet teeth (16b)% (17bl) are on the engagement side, so the first pulley (b) is also synchronized with the second pulley (b). The wire (9) is then rotated and the wire (9) is sent out.At this time, the elongation of the wire is not absorbed.

As mentioned above, since the pulleys for winding and feeding are arranged in parallel in the present invention, the entire structure can be made thin and compact, and it can meet the demand for thinner door panels in recent automobiles. It is. Further, by providing a brake means such as a washer spring or a thinly wound spring for each pulley, reliable operation can be ensured.

Furthermore, in the window regulator of the present invention, the elongation of the wire is automatically absorbed by raising and lowering the window glass, so there is no need to adjust the wire length every time the wire elongates.

Furthermore, after attaching the window regulator to a car door or the like, it is possible to easily adjust the tension of the wire by simply operating a lever.

In addition, in the window regulator of the present invention, the driving device (1) and the driven device (2) are firmly connected by two parallel flexible conduits, and the wire is kept in tension inside. Because they are slidably guided, the window regulator can be handled as one compact unit1.
It can be easily attached without being affected by the attachment state of the other, and can be handled as a substantially separate device. Because of these, it is extremely easy to remove sand from the door of a window regulator, etc. Further, there is no restriction that each device must be arranged in a two-dimensional manner, and it is easy to configure it three-dimensionally, for example, as in 11N6FIJ.

In addition, since there is a high degree of freedom in mounting the lid,
It is also highly versatile, and has the great advantage of being able to use a common window regulator for the doors of various types of automobiles, and reducing the amount of sagging.

Further, the window regulator of the present invention includes a wire (9),
Since the wire (to) is routed only at the top and is covered with the conduit (8), there is little risk of water droplets such as rainwater adhering to the wire, and there is no risk of the cable being routed below the guide rail (4). Cable guide (8).

Since only the J-id member (γ), which is less likely to retain water droplets than a balance spring mechanism or the like, is placed, rust is less likely to occur, and the drawbacks such as failure to operate due to deep freezing are also eliminated. I can do it.
