TECHNICAL FIELD OF THE INVENTION
The present invention relates to a window regulator device for raising and lowering a window glass of a vehicle and the like, and a carrier plate used for the same, and more particularly to a structure for attaching a cable terminal to a carrier plate in a cable type window regulator device. .
[0002]
[Prior art]
Regarding a “carrier plate” used in a so-called “wire-type” window regulator that moves up and down (opens and closes) a window glass of a vehicle or the like by moving a wire cable back and forth, a technique described in Patent Document 1 or Patent Document 2 is used. Has been proposed in the past.
[0003]
[Patent Literature 1] Japanese Patent Publication No. 3-39593 (Page 1, Page 2, Figure 3, Figure 4)
[0004]
First, the technique described in Patent Document 1 is such that a wire locking portion (9) is provided on a carrier plate (7), and the wire locking portion (9) includes a front wall surface (9a) and a rear wall surface (9b). , A left and right wall (9c) and an upper wall (9d). The upper wall surface (9d) is provided with a locking work hole (21) and a notch groove (23), and the wire end stoppers (17, 19) are inserted through the locking work hole (21) and cut out. The end of the wire is attached via the groove (23).
[0005]
However, in the carrier plate having the above configuration, the temperature inside the door panel becomes high or the wire terminal is held depending on the use environment of the vehicle to which the carrier plate is mounted and the operating condition of the window regulator device by the user. Or a sudden load acts on the wire locking portion (9).
[0006]
When used in such a harsh environment for a long period of time, since the wire locking portion (9) is formed in a box shape having a notch groove (23), the wire locking portion (9) is formed. 9) The left and right side surfaces and the like are deformed and the notch groove (23) is expanded, which may cause the wire terminal to "fall off" or "fall off", and the window regulator device may become inoperable.
[0007]
[Patent Document 2] Japanese Patent Publication No. Hei 7-18294 (Page 2, Page 3, Figure 4)
[0008]
Then, the technique of patent document 2 is demonstrated. The carrier plate described in Patent Document 2 has a wire holding portion (10) provided continuously with the lower slit guide (3 ′).
[0009]
As shown in FIG. 6, the wire holding portion (10) has a vertical portion (27) having a substantially L-shaped cross section, thereby preventing the wire and the wire end from falling off. Has become.
[0010]
However, according to the technology described in Patent Document 2, the wire holding portion (10) is formed of a hanging portion (27) having a substantially L-shaped cross section, and thus the hanging portion (27) is configured to “wire” the wire. The wire holding portion (10) is deformed in the harsh use environment as described above, so that the wire terminal is "disengaged" or "dropped out". In some cases, the window regulator device became inoperable.
[0011]
When the window regulator device becomes inoperable in this way, the window glass cannot be opened and closed. The window regulator device is one of the components that must not be broken down, especially in severe cold weather such as at night in the middle of winter or during rainfall. If the window glass cannot be opened or closed, it is often added that the wire cable is dropped due to deformation of the carrier plate.
[0012]
[Problems to be solved by the invention]
The above-mentioned problems are caused by the fact that the holding portion is deformed due to a decrease in the rigidity of the resin at a high temperature because at least one portion has an open structure for passing the cable in order to easily assemble the (wire) cable terminal. There is a cause.
[0013]
The present inventor has noticed the existence of the above-mentioned cause and completed the present invention. The object of the present invention is as follows.
[0014]
That is, by inserting the guide rail into the cable entry path (assembly path) after assembling the (wire) cable terminal section, even if the cable holding section is deformed, the window regulator device cannot operate. It is an object of the present invention to provide a carrier plate that can avoid and reliably support a window glass.
[0015]
[Means for Solving the Problems]
Means taken by the present invention to solve the above-mentioned problems will be described below with reference numerals used in the embodiments described below.
[0016]
First, according to the first aspect of the present invention, the cable terminal 200 is held by the cable holding unit 10 provided on the flat board, and the cable is advanced and retracted, so that the slide rail 310 is mounted on the guide rail 300. The cable holding portion 10 is made of a synthetic resin, and the opening 12 and the opening 12 through which the cable terminal 200 enters are provided in the carrier plate 100 for moving the window glass placed and fixed on the glass holding portion 30 by sliding. And a side wall 11 for holding the cable terminal 200. The side wall 11 is held by the sliding wall 310 of the guide rail 300 after holding the cable terminal 200, and the side wall 11 is deformed. Is prevented.
[0017]
That is, in the invention according to the present invention, the sliding wall 310 erected on the guide rail 300 as a separate member presses the side wall 11 of the cable holding portion 10 formed of a synthetic tree on the carrier plate 100. This prevents the side wall 11 from being deformed in the expanding direction and prevents the cable terminal 200 held by the side wall 11 from dropping off the carrier plate 100.
[0018]
In general, the guide rail 300 in the window regulator device often forms a sliding wall 310, a reinforcing wall 320, or the like by bending the vicinity of a side end in order to improve its own strength. The present invention focuses on the sliding wall 310, and the sliding wall 310 presses the side wall 11 of the cable holding unit 10. Unlike the curved substantially flat portion of the guide rail 300, the sliding wall 310 is less deformed and displaced depending on the operation state of the window regulator device, so that the side wall portion 11 can be stably pressed.
[0019]
Therefore, according to the present invention, since the cable holding portion 10 formed of a synthetic resin can be prevented from being deformed, the cable holding portion 10 is prevented from being deformed and the cable terminal 200 falling off. it can. Therefore, it is possible to prevent the window regulator device from becoming inoperable due to the drop of the cable terminal 200.
[0020]
Next, in the invention according to claim 2, in the carrier plate 100 according to claim 1, the opening 12 in the cable holding portion 10 is formed by the sliding wall 310 of the guide rail 300 after the cable terminal 200 enters. It is closed and prevents the cable terminal 200 from falling out of the opening 12.
[0021]
According to the present invention, since the opening 12 which is the cable entry path is closed by the sliding wall 310 erected on the guide rail 300, the cable terminal 200 comes out following the reverse of the entry path. It is possible to prevent that.
[0022]
A window regulator device according to a third aspect of the present invention provides a carrier plate 100 according to the first or second aspect, a guide rail 300 on which a sliding wall 310 is erected, and the carrier plate 100 by moving forward and backward. And a cable to be moved up and down.
[0023]
According to the present invention, since the cable holding portion 10 formed of a synthetic resin can be prevented from being deformed, the cable terminal 200 can be prevented from falling out of the carrier plate 100, and thus the window regulator device itself can be prevented. It is possible to improve durability.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Subsequently, a preferred embodiment of the present invention having the above configuration will be described below with reference to the drawings.
[0025]
FIGS. 1 and 2 show a carrier plate 100 according to the present invention, and FIG. 3 shows a window regulator device in which the carrier plate 100 is slidably mounted on a guide rail 300. . This window regulator device is used by sliding a carrier plate 100 on a guide rail 300 by moving a cable having a terminal portion (hereinafter, referred to as a “cable terminal 200”) held on the carrier plate 100. It is.
[0026]
As shown in FIGS. 1 and 2, the carrier plate 100 according to the present embodiment includes a “cable holding portion 10” that holds a cable terminal 200 on a flat board made of a synthetic resin, and a guide rail. A “guide groove 20” that regulates the position of the present carrier plate 100 on 300, and a “glass holding portion 30” formed of a mounting hole for mounting and fixing a window glass are integrally provided. It is needless to say that the present invention is not particularly limited to the above-described configuration, and may be configured by coating a substrate formed of metal with a synthetic resin, or may be formed on a substrate formed of metal with a synthetic resin. A cable holding section 10 "or the like may be provided.
[0027]
Here, in the above configuration, the “cable holding unit 10” has the “opening 12” for allowing the cable terminal 200 to enter and the “side wall 11” for holding the cable terminal 200.
[0028]
More specifically, as shown in FIG. 4, for example, a space is provided in a substantially L-shape communicating with the opening 12, and a “storage portion” that is a space for housing the cable terminal 200 is provided. A part of the space is isolated by the side wall 11. Then, as shown in FIGS. 4 and 5, the cable terminal 200 is caused to enter the “storage portion” inside the carrier plate 100 through the opening 12, and as shown in FIG. It is locked on the side wall 11.
[0029]
Thereafter, as the guide rail 300 is inserted into the “guide groove 20” described later, the sliding wall 310 erected on the guide rail 300 enters the opening 12. As the sliding wall 310 enters the opening 12, the side wall 11 holding the cable terminal 200 is pinched.
[0030]
In the present invention, since the sliding wall 310 clamps the side wall portion 11, even if a load is applied to the cable holding portion 10 due to a “high temperature environment” or an “excessive load”, the deformation is generated such that the cable falls off. Can be prevented beforehand. Therefore, the durability of the window regulator device on which the carrier plate 100 is mounted can be significantly improved.
[0031]
The sliding wall 310 of the guide rail 300 has a role of clamping the sliding wall 310 and a role of closing the opening 12. By closing the opening 12 in this manner, it is possible to prevent the cable terminal 200 from escaping from the opening 12 following the “reverse of the approach path” as shown by the arrows in FIGS. 5A and 5B. It is.
[0032]
In this embodiment, the cable terminal 200 is configured by fixing a block formed in a cube shape to the end of the cable. The cable terminal 200 can be prevented from rotating in the cable holding unit 10 by locking the block formed in a cube shape at the side wall 11. That is, it is possible to effectively prevent the generation of noise due to the rotation of the cable terminal 200.
[0033]
Further, the dimension of one side of the cube-shaped block is, as shown in FIGS. 5A and 5B, a cross-sectional dimension of the “substantially L-shaped space” in the cable holding portion 10 regulated by the sliding wall 310. Is also preferably large. By adopting such a configuration, even when the cable terminal 200 jumps out of the storage portion, it is possible to more effectively prevent the cable from coming out of the carrier plate 100.
[0034]
In the present embodiment, a configuration in which the vicinity of the upper end of the opening 12 is brought into close contact with the sliding wall 310 and the contact portion is formed narrower in the vertical direction to reduce sliding resistance. Has become. In other words, the cable is prevented from coming out of the gap between the opening 12 and the sliding wall 310 by bringing the vicinity of the upper end of the opening 12 into close contact with the sliding wall 310. Of course, if the sliding resistance is not taken into consideration, it is not necessary to form the contact portion narrow.
[0035]
Here, the “guide groove 20” regulates the position of the main carrier plate 100 on the guide rail 300. Specifically, when the window regulator device on which the carrier plate 100 is mounted is installed on a door panel of a vehicle and the door is opened and closed, for example, the window plate is separated from the guide rail 300 with respect to the carrier plate shown in FIG. The load in the direction acts. Even if such a load is generated, the provision of the guide groove 20 can prevent the carrier plate 100 from being displaced from the specified position on the guide rail 300.
[0036]
In this embodiment, the guide groove 20 is formed integrally with the carrier plate 100 with a synthetic resin, and is formed so as to extend around the rear surface of the guide rail 300, as shown in FIGS. 2, 3, and 5. However, the present invention is not particularly limited to this configuration. For example, the guide groove 20 formed of a metal may be covered with a synthetic resin, or the guide groove 20 formed of a synthetic resin may be provided on a substrate formed of a metal.
[0037]
In this embodiment, as shown in FIGS. 1, 2 and 5, a "leaf spring portion 21" is integrally formed near the "guide groove 20". When the guide rail 300 is mounted in the guide groove 20, the leaf spring portion 21 presses the guide rail 300. This contributes to improving the adhesion between the guide rail 300 and the guide portion and increasing the adhesion between the sliding wall 310 and the upper end of the opening 12 of the cable holding portion 10.
[0038]
The guide rail 300 mounted in the “guide groove 20” has a substantially F-shaped cross section in this embodiment. That is, the reinforcing wall 320 is erected by bending one end of the flat plate, and the sliding wall 310 for pinching the side wall portion 11 is erected by bending an intermediate portion near the other end. The present invention is not particularly limited to this configuration in order to achieve the object of the present invention, and the sliding wall 310 may be disposed at the end of the guide rail 300 as long as the cable holding unit 10 can be pressed. Alternatively, a configuration may be adopted in which a plurality of sliding walls 310 are provided to press the cable holding portions 10 respectively. Of course, the reinforcing wall 320 may serve as the sliding wall 310.
[0039]
As described above, the present invention has been described with the embodiments. One of the features of the present invention is that the cable holding portion 10 of the carrier plate 100 is pressed by the sliding wall 310 of the guide rail 300. . Therefore, even if there is a slight difference in the configuration without departing from the essence of the present invention, as long as it has the same operation and effect as the present invention, it belongs to the technical scope of the present invention.
