[0001]
TECHNICAL FIELD OF THE INVENTION
According to the present invention, one guide member is provided along the vertical direction of the window glass, a carrier plate to which the window glass is fixed and which can be slid by fitting with the guide member, and moving the carrier plate up and down. The present invention relates to a window regulator device that includes a drive cable and the like and that moves up and down a window glass.
[0002]
[Prior art]
Conventionally, in a window regulator device, one guide member disposed along the vertical direction of the window glass, a carrier plate to which the window glass is fixed and slidable by fitting with the guide member, A drive cable for elevating and lowering the carrier plate, the drive cable is locked to the carrier plate, both ends of the drive cable are wound around a winding drum, and the winding drum is rotated, whereby the window glass is rotated. Is raised and lowered.
[0003]
However, according to the related art, the cable for driving the carrier plate is locked at one position with the carrier plate. Therefore, when the cable drives the carrier plate, the cable is driven around the locked position. As the carrier plate is tilted, there is a possibility that the window glass fixed to the carrier plate may be tilted, and when the window glass is tilted, the sliding resistance between the guide member and the carrier plate increases, and the operation is stopped. There is a risk of malfunction.
[0004]
[Problems to be solved by the invention]
In order to avoid the above-mentioned operation problems, a device was developed in which two guide members were arranged on both sides of the window glass at a predetermined distance, and one drive cable was wound between the six guide rollers. However, since the number of parts increases, there is a problem that it is difficult to secure the accuracy of the parts and assemble them, and the cost increases.
[0005]
Japanese Utility Model Publication No. 8-2375 discloses a device in which two guide members are arranged on both sides with a predetermined distance therebetween, and two drive cables are wound around four guide rollers. However, the use of two guide members requires two carrier plates, which also cannot avoid the problem that the increase in the number of components makes it difficult to secure the accuracy of the components and increase the cost.
[0006]
In view of the circumstances described above, an object of the present invention is to provide a window regulator device that uses a single guide member and that prevents skewing of a window glass with a simple configuration.
[0007]
[Means for Solving the Problems]
In order to solve such a problem, the invention described in claim 1 is proposed.
The feature of the present invention has one guide member disposed along the vertical direction of the window glass, and a carrier plate to which the window glass is fixed, provided with a fitting portion that fits with the guide member, In a window regulator device configured such that the carrier plate can be raised and lowered by two drive cables, locking portions for locking the two drive cables are provided at two places on both sides of the carrier plate in the vertical direction, The other ends of the two drive cables locked by the locking portions are wound around a drum of one drive motor, and the carrier motor is driven by the drive motor via the two drive cables. That is, it is configured.
[0008]
Therefore, according to the present invention, since the carrier plate is driven from both sides with the fitting portion between the carrier plate and the guide member interposed therebetween, the carrier plate is prevented from tilting and the tilting of the window glass is prevented, and the friction of the sliding portion is reduced. Since the resistance can be prevented from rising, there is no problem in raising and lowering the window glass.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. However, unless otherwise specified, dimensions, materials, shapes, relative positions, and the like of the components described in this embodiment are not intended to limit the scope of the present invention, but are merely illustrative examples. Not just.
[0010]
FIG. 1 is a configuration diagram of a window regulator device according to a first embodiment of the present invention.
In FIG. 1, a window regulator device 1A includes an I-shaped regulator rail (guide member) 2A, and a carrier plate 3 to which a lower portion of a window glass 4 is fixed is slidably disposed on the guide member 2A. Have been.
The regulator rail 2A is disposed such that the center of gravity of the window glass 4 is located at an intermediate portion between two drive cables engaged with a gap with the carrier plate 3 fitted to the regulator rail 2A. ing.
[0011]
The carrier plate 3 has a fitting portion 3b for sandwiching the guide member 2A as shown in the XX section, and locking portions for engaging the drive cables 9 and 10 on both ends of the fitting portion 3b. 3a, 3a are provided. The locking portion is formed in a groove shape, and has a structure in which the covering portions 14 and 15 which are covered with a lead or an iron plate or the like and fixed by caulking are fixed to the intermediate portions of the tables 9 and 10.
[0012]
Guide rollers 5, 6, 7 and 8 are rotatably arranged at upper and lower ends 2Aa and 2Ab of the guide member 2A. The left cable 9 is guided through the guide rollers 5 and 7, and the right cable 10 is guided. It is wound around a drum 11A driven forward and reverse by a drive motor fixed to a bracket 13 via rollers 6 and 8.
The bracket 13 is configured to be adjustable in the direction of arrow 30 in FIG.
[0013]
The drum 11A is configured to be rotatable forward and backward by a reduction mechanism that reduces the rotation of the motor 12 disposed on the bracket 13 by a worm gear and a pinion gear.
As shown in FIG. 2A, the left cable 9 and the right cable 10 are configured to be wound around a spiral groove of a groove 11Ab provided on the drum 11A. The details will be described in detail with reference to FIG.
[0014]
As shown in FIG. 3, spiral grooves are formed in the grooves 11Ab provided in the drum 11A, and the spiral grooves are provided with concave portions 11Aa corresponding to both ends of each cable, respectively. A connecting piece (not shown) for engaging and connecting to the drum 11A fixed to the end of each cable is fitted and fixed, so that each cable can be wound up and pulled out.
[0015]
Since the first embodiment is configured as described above, when the drum 11A rotates clockwise by the rotation of the motor 12, the carrier plate 3 rises, the door window is shielded by the window glass 4, and the drum 11A is When rotated counterclockwise, the carrier plate 3 descends, and the door window opens. At this time, the left cable 9 and the right cable 10 both pull the locking portions 3a, 3a of the carrier plate 3, so that the carrier plate 3 is driven from both sides with the fitting portion 3b with the guide member 2A interposed therebetween. As a result, the carrier plate 3 does not tilt and the window glass 4 does not move skewing, and the vertical movement is smoothly performed.
[0016]
As described above, in the first embodiment, since two cables are used as compared with the conventional single cable use, the load per cable is halved, and the durability is improved. Also, compared to the conventional two-cable use, only one guide member is required, so only one carrier plate is required, the number of parts is reduced, the mounting of the window glass to the carrier plate becomes easy, and the accuracy of assembling the parts is improved. However, the number of parts assembling steps can be reduced, and the cost can be reduced.
[0023]
【The invention's effect】
As described above, the present invention prevents an increase in sliding resistance between the carrier plate and the guide member and between the window glass and the run channel because the inclination of the window glass is eliminated when the window glass is raised and lowered. It is possible to provide a window regulator device that can prevent wear of the channel, does not generate abnormal noise, and has improved durability.
