Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automotive window regulator that raises and lowers a window glass disposed between an inner panel and an outer panel of a door body.
[0002]
[Prior art]
Conventionally, it is well known that a wire-driven window regulator for raising and lowering a window glass is attached to a side door supported on a side portion of a vehicle body or a back door supported on a rear portion of the vehicle body (for example, JP-A-2- No. 217582).
[0003]
In this type of conventional window regulator, the guide member is fixed to the inner panel of the door body through brackets fixed to the upper and lower portions, and the first and second pulleys are rotatably supported by the respective brackets. Has been. A wire is wound around the two pulleys and a drum that is rotatably supported with respect to the inner panel, and each end of the wire is locked to a window glass support member that supports a lower portion of the window glass. Thus, the slider attached to the window glass support member is slidably fitted to the guide surface of the guide member.
[0004]
When the drum is rotated to drive the wire, the window glass support member connected to the wire moves up and down together with the window glass. At this time, the slider fitted to the guide surface of the guide member slides while being guided by the guide member, whereby the window glass moves up and down in a predetermined path. The guide member is disposed between the inner panel and the outer panel and closer to the inner panel than the window glass. The guide member has a guide surface on the side facing the outer panel. Further, the window glass support member occupies a position closer to the outer panel than the guide member.
[0005]
As described above, the window glass can be raised and lowered correctly by this type of conventional window regulator. However, in the conventional window regulator, the first and second pulleys are supported on the surface of each bracket facing the outer panel, and the window glass supporting member that supports the window glass is also closer to the outer panel than the guide member. When the diameter of the first and second pulleys is increased, the window glass support member is moved up and down when the window glass support member is moved up and down. May interfere with each pulley. For this reason, conventionally, the diameter of the pulley has to be set small so that the window glass support member does not interfere with the first and second pulleys. However, when the diameters of the first and second pulleys are reduced as described above, the wires wound around the pulleys are bent with a large curvature along the peripheral surfaces of the pulleys, so that a large stress is generated on the wires. As a result, the durability of the wire may be reduced. This is the first drawback of the prior art.
[0006]
In addition, the bracket that supports each pulley is fixed to the inner panel by screws at a portion different from the rotation axis of the pulley. According to such a configuration, the bracket fixing position with respect to the inner panel and the rotation axis of the pulley The position of will be greatly separated. For this reason, the bracket portion supporting the pulley vibrates due to an impact when the automobile travels, and this vibration is directly transmitted to the pulley, causing the pulley to vibrate. As described above, since a large external vibration force always acts on the pulley during traveling of the automobile, its durability may be reduced. This is the second drawback of the prior art.
[0007]
Further, the guide member is fixed to the inner panel via upper and lower brackets. However, if such a bracket is used, the number of parts of the wind regulator increases accordingly, and the disadvantage that the weight and cost increase is inevitable. This is the third drawback of the prior art.
[0008]
[Problems to be solved by the invention]
A first object of the present invention is to provide an automobile window regulator that eliminates the above-mentioned conventional first drawback.
[0009]
A second object of the present invention is to provide an automotive window regulator which can eliminate all the above-mentioned conventional first, second and third drawbacks.
[0010]
[Means for Solving the Problems]
In order to achieve the first object, the present invention is an automotive window regulator that raises and lowers a window glass disposed between an inner panel and an outer panel of a door body, and is fixed to the inner panel. A guide member having a guide surface on the side facing the outer panel, a window glass support member for supporting a lower portion of the window glass, and attached to the window glass support member, and slidable on the guide surface of the guide member A slider that moves up and down with the window glass support member and the window glass while being fitted and guided to the guide surface, and first and second pulleys arranged on the upper side and the lower side of the guide member, respectively A drum that is driven to rotate, and a wire that is wound around the first and second pulleys and the drum and that is locked to the window glass support member. The guide member is disposed between the inner panel and the outer panel, and is disposed closer to the inner panel than the window glass, and the window glass supporting member occupies a position closer to the outer panel than the guide member. In the window regulator, the first and second pulleys are disposed between the guide member and the inner panel, and rotate on the upper and lower portions of the guide member via first and second pins, respectively.

The bottom wall 20, the side wall 21, and the flange wall 22 integrally form a substantially U-shaped cross-sectional shape, and a slit-like opening 23 extending long in the longitudinal direction of the guide member 9 between both the flange walls 22. Is formed. As described above, the guide member 9 has the opening 23 on the side facing the outer panel 4 and the substantially U-shaped guide surface 10 on the surface facing the outer panel 4.
[0018]
The window regulator 7 includes a window glass support member 11 that supports the lower portion of the window glass 6 and a slider 12 attached to the window glass support member 11 as shown in FIGS. 1 to 3. Although the number of sliders 12 can be set as appropriate, in the illustrated example, two sliders 12 are provided. The window glass supporting member 11 occupies a position closer to the outer panel 4 than the guide member 9 and closer to the inner panel 5 than the window glass 6.
[0019]
The window glass 6 and the window glass support member 11 may be fixed to each other by, for example, an adhesive or a screw to support the window glass 6 on the window glass support member 11. In the illustrated example, the window glass support member 11 is formed on the window glass support member 11. By fitting a sliding member 14 fixed to the window glass 6 with screws and nuts into the pair of elongated holes 13 extending in the horizontal direction, the window glass 6 is attached to the windows 13 so as to be slidable in the horizontal direction. It is supported by the glass support member 11. Details of this configuration are disclosed in Japanese Patent Laid-Open No. 2-217582.
[0020]
On the other hand, as clearly shown in FIG. 4, the slider 12 is fitted to the U-shaped guide surface 10 of the guide member 9 so as to be slidable in the longitudinal direction of the guide member 9. It protrudes through the opening 23 of the guide member 9, and its tip is fitted and fixed in a mounting hole 15 formed in the window glass support member 11.
[0021]
Further, the window regulator 7 includes first and second pulleys 16 and 17 disposed on the upper side and the lower side of the guide member 9, respectively. These pulleys 16 and 17 are disposed between the guide member 9 and the inner panel 5 as clearly shown in FIG. 2, and the above-described first and second pins 18 are provided on the upper and lower portions of the guide member 9. , 19 are supported so as to be freely rotatable.
[0022]
The first and second pins 18 and 19 have their heads 24 and 25 fixed by being caulked to the bottom wall 20 of the guide member 9, and penetrate the bottom wall 20 toward the inner panel 5. In addition, the nuts 26 and 27 are respectively screwed into the male screws formed in the pins 18 and 19 through the holes formed in the inner panel 5, whereby the first and second pins 18 and 19 are connected. It is fixed to the inner panel 5 immovably. The first and second pins 18 and 19 protrude from the guide member 9 almost horizontally toward the inner panel 5.
[0023]
In this way, the guide member 9 is fixed to the inner panel 5 via the first and second pins 18 and 19, and the first and second pulleys 16 and 17 are rotatable on the pins 18 and 19. It is supported by. The first and second pulleys 16 and 17 are rotatably supported with respect to the inner panel 5 via the first and second pins 18 and 19, respectively.
[0024]
Further, the window regulator 7 includes a drum 28 that is rotatably supported with respect to the inner panel 5. In this example, the drum 28 is rotationally driven by a motor 29 that is fixedly supported with respect to the inner panel 5. It is configured. That is, as shown in FIG. 5, the motor 29 is supported by the bracket 30 fixed to the bottom wall 20 of the guide member 9 fixed to the inner panel 5, and the drum 28 is fixed to the output shaft of the motor 29. The drum 28 is supported rotatably with respect to the inner panel 5 via the motor 29, the bracket 30, the guide member 9, and the first and second pins 18, 19.
[0025]
The drum 28 is rotatably supported by the inner panel 5 directly or through an intermediate member, and the drum is connected to a handle (not shown) that is rotated by an occupant in the passenger compartment. The drum can also be configured to rotate by operation.
[0026]
Further, as shown in FIGS. 1 to 3, the window regulator 7 has a wire 31 wound around the first and second pulleys 16 and 17 and the drum 28 described above. The wire 31 is locked to the window glass support member 11. In this example, each end portion in the longitudinal direction of the wire 31 is locked to the window glass support member 11. That is, as shown in FIGS. 2 to 4, the wire locking box 32 is fixed to the surface of the window glass support member 11 facing the inner panel 5, and each end of the wire 31 is connected to the wire locking box 32. The locking block 33 is fixed to the tip of each end through a small hole formed in the wall of the wire, thereby preventing the end of the wire 31 from coming out of the wire locking box 32. ing. In this way, instead of locking each end of the wire 31 to the window glass support member 11 via an intermediate member such as the wire locking box 32, each end is directly engaged with the window glass support member 11. You may stop.
[0027]
When an occupant who has boarded the vehicle equipped with the door 1 operates a motor 29 by operating a switch (not shown) provided in the passenger compartment, the drum 28 is driven to rotate, whereby the wire 31 travels. When driven, the first and second pulleys 16 and 17 rotate about the central axes of the first and second pins 18 and 19, respectively. Thus, when the wire 31 is driven to travel, the window glass support member 11 locked thereto is moved up and down. At this time, the slider 12 moves up and down together with the window glass support member 11 and the window glass 6 while being guided by the guide surface 10 of the guide member 9, and the window glass 6 draws its predetermined locus in the direction of arrow A (FIG. 1). Go up and down.
[0028]
Here, in order to clarify the advantages of the above-described window regulator 7, the disadvantages of the conventional window regulator described above will be described with reference to FIG. In the window regulator 7 shown in FIG. 6, the guide member 9 is fixed to the inner panel 5 via brackets 34 and 35 fixed to the upper part and the lower part thereof, and the first and second brackets 34 and 35 are attached to the first and second brackets 34 and 35, respectively. Pulleys 16 and 17 are rotatably supported. Moreover, these pulleys 16 and 17 are supported by the surfaces of the brackets 34 and 35 on the side facing the outer panel 4, and the window glass support member 11 is also disposed at a position closer to the outer panel 4 than the guide member 9. The pulleys 16 and 17 and the window glass support member 11 are located on substantially the same plane. For this reason, when the diameters of the first and second pulleys 16 and 17 are set large, the window glass support member 11 that moves up and down interferes with the pulleys 16 and 17. Therefore, in the conventional window regulator 7, the diameters of the pulleys 16 and 17 cannot be increased. As a result, the wire 31 is wound around the pulleys 16 and 17 with a large curvature, and a large stress is generated on the wire 31. I couldn't escape the shortcomings.
[0029]
Further, since the brackets 34 and 35 are fixed to the inner panel 5 by screws 36 and 37 at positions away from the pulleys 16 and 17, when the automobile travels, the bracket portion that supports the pulleys 16 and 17 vibrates. As a result, the pulleys 16 and 17 vibrate, which may reduce the durability thereof.
[0030]
Further, since the window glass support member 9 is fixed to the inner panel 5 via the brackets 34 and 35, the number of parts of the window regulator 7 is increased by the amount of the brackets 34 and 35.
[0031]
On the other hand, in the embodiment shown in FIGS. 1 to 5, as described above, the first and second pulleys 16 and 17 are arranged between the guide member 9 and the inner panel 5. The window glass support member 11 is located on the side of the guide member 9 facing the outer panel 4, that is, on the guide surface 10 side. The first and second pulleys 16 and 17 and the window glass support member 11 are located on opposite sides of the guide member 9. For this reason, even if the diameters of the first and second pulleys 16 and 17 are increased to a desired value as shown in FIGS. 1 to 3, the pulleys 16 and 17 are moved to the window glass support member 11 that moves up and down. There is no risk of interference. In this way, the diameters of the first and second pulleys 16 and 17 can be set larger than the conventional ones, and thereby the curvature of the wire 31 curved along the peripheral surfaces of these pulleys 16 and 17 is reduced. be able to. Therefore, the stress acting on the wire 31 can be kept small, and its durability can be enhanced.
[0032]
Moreover, the first and second pulleys 16 and 17 are rotatably supported on the upper and lower portions of the guide member 9 via the first and second pins 18 and 19, respectively. Since the guide member 9 is directly fixed to the inner panel 5 by the pins 18 and 19, the portions where the guide member 9 is fixed to the inner panel 5 and the positions of the rotation axes of the first and second pulleys 16 and 17 are used. Match. For this reason, it is assumed that the guide member 9 vibrates around the portions of the first and second pins 18 and 19 that are the fixed positions by the external vibration force received when the pulleys 16 and 17 rotate or when the automobile travels. However, since the first and second pulleys 16 and 17 are disposed at this portion, the pulleys 16 and 17 do not vibrate vigorously. Even when the guide member 9 vibrates, it does not vibrate substantially at its fixed position, that is, at the portions of the first and second pins 18 and 19, or the vibration is very slight. In addition, since the second pulleys 16 and 17 are provided, the pulleys 16 and 17 do not vibrate substantially or even if they vibrate, the amplitude thereof is extremely small. Thus, it can prevent that a big vibration generate | occur | produces in a 1st and 2nd pulley, and can improve the durability effectively.
[0033]
Furthermore, since the guide member 9 is directly fixed to the inner panel 5 by the first and second pins 18 and 19 without using a bracket, the number of parts of the window regulator 7 can be reduced, and its cost and weight are reduced. Can be reduced.
[0034]
As described above, the example in which the present invention is applied to the side door window regulator provided on the side portion of the vehicle body has been described. However, the present invention is widely applied to the wind regulator attached to the back door that can be opened and closed at the rear portion of the vehicle body. Applicable. It is also applicable to window regulators for sashless doors without window frames.
[0035]
【The invention's effect】
According to the configuration of the first aspect, the first and second pulleys are disposed between the guide member and the inner panel, and are located on the side opposite to the window glass support member with the guide member interposed therebetween. Therefore, the diameters of the first and second pulleys can be set large without considering interference with the window glass support member. Thereby, the stress which arises in a wire can be reduced and the durability can be improved.
[0036]
According to the configuration of the second aspect, the first and second pulleys are disposed between the guide member and the inner panel, and the first and second pulleys are arranged above and below the guide member. In addition, since the first and second pins are rotatably supported, the fixed position at which the guide member is fixed to the inner panel and the rotation axes of the first and second pulleys, respectively, Since it becomes the location of the 1st and 2nd pin, it can prevent that the 1st and 2nd pulley vibrates violently, and can improve durability of the 1st and 2nd pulley by this.
[0037]
Furthermore, in the structure of Claim 2, since the guide member is being fixed to the inner panel via the 1st and 2nd pin without passing through a bracket, the number of parts of a window regulator can be reduced, The cost and weight can be reduced.
