[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window panel elevating device.

[0002]

2. Description of the Related Art FIGS. 8 and 9 show a conventional vehicle window panel elevating device (for a similar structure, see Japanese Patent Application Laid-Open No. 63-60375).

This door is of a sashless type used for a hard-top car or the like, and has a front rail 1, a center rail 2, and a rear rail 3 inside which various rail brackets 4, 5, 6, 7 are provided. It is fixed by. Each of the rails 1, 2, and 3 has a substantially C-shaped cross section provided with a flange portion 9 with a lip 8 facing inward on both sides. Rollers 10, 11, and 12 are respectively engaged so as to be slidable up and down. Each of the guide rollers 10, 11,
12, the window panel 1 together with the panel plate 13
4 are attached. The upper and lower positions of the guide rollers 10 and 12 of the front rail 1 and the rear rail 3 and the guide rollers 11 of the center rail 2 are different, and by such a three-point support system, the window panel 14 has three rails 1 and 2. Attached to a few.

[0004] A regulator arm R is connected to the panel plate 13, and the window arm 14 can be vertically moved up and down by the regulator arm R. The position of the window panel 14 in the front-rear direction Y and the door thickness direction X is regulated by the guide roller 1.
This is achieved by engaging the grooves M of 0, 11, 12 with the ends of the lips 8 of the rails 1, 2, 3.

[0005]

However, in such a conventional technique, three rails 1, 2, 3 and various rails for attaching the rails 1, 2, 3 to the inside of the door for raising and lowering the window panel 14 are disclosed. Brackets 4, 5, 6,
Since many parts such as 7 are required, it is very disadvantageous in terms of assembly workability.

Further, the accuracy between the three rails 1, 2, and 3 is hard to be obtained, and there is a possibility that the mounting accuracy of the window panel 14 may be adversely affected.

Further, when adjusting the inclination of the window panel 14 in the door thickness direction X, the inclination must be adjusted from all the inclinations of the three rails 1, 2, and 3.
It is difficult to adjust the position of the window panel 14. In particular, when three rails 1, 2, and 3 are used as in the conventional example, the groove M of the guide rollers 10, 11, and 12 is connected to the end of the lip 8 of each rail 1, 2, and 3. To the rails 1, 2, 3 and the guide rollers 10,
Since there is no "play" in the front-rear direction Y and the door thickness direction X between the rails 11 and 12, each rail 1, 2, and 3 is required to have strict sectional dimensional accuracy. The production and handling of the product itself must be strictly performed.

The present invention has been made by paying attention to such a conventional technique, and it is easy to perform an assembling work and a work of adjusting a mounting of a window panel, and to improve a mounting accuracy of a window panel for an automobile. Provide a lifting device.

[0009]

According to a first aspect of the present invention, there is provided a window panel elevating / lowering apparatus for a vehicle, wherein a base of a press-formed product having an attachment portion to a door body is substantially C-shaped in cross-section located substantially at the center of front and rear of the base. A window panel elevating and lowering device for an automobile, wherein a center plate is provided and a carrier plate is mounted on the center rail via a guide roller so as to be vertically movable, so that a window panel mounted on the carrier plate is raised and lowered. Each of the front end and the rear end of the base is a rail portion serving as a position reference in the door thickness direction of the carrier plate, and only one of the front end and the rear end serves as a position reference in the front-rear direction of the carrier plate. While bending the guide flange,
A first slider slidable up and down with the front end or rear end of the carrier plate having the guide flange in the door thickness direction and the guide flange held in the front-rear direction; A second slider slidable in the vertical direction with the front end or the rear end without the flange sandwiched in the door thickness direction.

According to a second aspect of the invention, there is provided an automobile window panel elevating device, wherein a front end of a shaft fixed to the carrier plate is fitted to the first slider, and the shaft relative to the first slider is centered on the front end. Is in a variable state.

According to a third aspect of the present invention, there is provided a window panel elevating device for an automobile, wherein a wire member moved by a motor is connected to the carrier plate, so that the carrier plate is moved up and down.

[0012]

According to the first aspect of the present invention, each of the front end and the rear end of the base is used as a rail portion serving as a position reference in the thickness direction of the door of the carrier plate, and is guided. Since the flange can be used as a position reference in the front-rear direction, the conventional structure requires only one center rail, so that the number of parts can be significantly reduced, the number of assembling steps is reduced, and workability is extremely advantageous.

Further, since the base is a press-formed product,
The shape is constant, and the positional accuracy of the front end and the rear end used as the rails is high. Therefore, the position of the carrier plate in the door thickness direction and the front-rear direction is determined based on the front end portion and the rear end portion having high position accuracy and the guide flange formed on one of the front end portion and the rear end portion. The mounting accuracy with respect to the base is increased, and as a result, the mounting accuracy of the window panel mounted on the carrier plate is improved.

Furthermore, since the front end and the rear end of the base having a fixed shape and high positional accuracy are used as the rails, the installation adjustment of the window panel is performed as follows.
Only the adjustment of the center rail position is required, and the work of adjusting the installation of the window panel becomes very easy.

According to the second aspect of the present invention, the tip of the shaft fixed to the carrier plate is fitted to the first slider, and the shaft with respect to the first slider is centered on the tip. Since the angle of the portion is variable, even if an error occurs in the positional relationship between the center rail and the guide flange, the error can be absorbed by changing the angle of the shaft portion, and the vertical sliding of the carrier plate There is no increase in dynamic resistance.

According to the third aspect of the present invention, a wire member which is moved by driving a motor is connected to the carrier plate so that the carrier plate is moved up and down. Even if the inclination in the vertical direction changes, it can flexibly cope with the change and does not increase the vertical sliding resistance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show a first embodiment of the present invention. First, FIG. 1 shows an overall view of a door according to this embodiment. Reference numeral 15 denotes an outer module as a “door body”. The outer module 15 is mainly formed of an outer panel 16 on the outside of the vehicle and an inner panel (not shown) joined to the inner side of the outer panel 16. A waist bracket 17, which is a part of the "door body", is attached to an upper portion of the inner panel (not shown). The waist bracket 17 includes the outer module 1
5 before mounting on the window panel elevating device 18.
The window panel 19 is mounted on the carrier plate 2 of the window panel lifting device 18.
0 is attached. In other words, this waist bracket 1
7, the window panel elevating device 18 and the window panel 19 are integrated into a module in advance, and the module is attached to the outer module 15. still,
At the innermost position of the door, a door trim (not shown) as an inner module is attached.

Next, the structure of the window panel elevating device 18 will be described with reference to FIGS. The window panel raising / lowering device 18 is of a type capable of changing the position of the window panel 19 in the front-rear direction Y in a curved manner and changing the inclination in the door thickness direction X three-dimensionally.

Reference numeral 21 denotes a base, which is a press-formed product of a steel plate. The base 21 has an overall shape in which the upper side is curved rearward so that the window panel 19 rises while moving rearward. At the upper end of the base 21, there are provided two front and rear adjustment bolts 23 as “attaching portions” which can be screwed into the screw holes 22 of the waist bracket 17. At the lower end, two mounting holes 24 are formed at the front and rear as "mounting portions" to be mounted to a lower portion of an inner panel (not shown) of the outer module 15.

A cross-section substantially C
A center rail 25 shaped like a letter is attached along the vertical direction. The lower part of this center rail 25 is a bracket 26
A support plate 27 is joined to the upper part of the center rail 25 through an adjust bolt 28, so that the upper part of the center rail 25 is Can be freely moved toward and away from the base 21. That is, the support plate 27 is sandwiched between the center rail 25 and two front and rear nut portions.
9 is provided, and an insertion hole 30 is formed in the base 21 corresponding to the nut portion 29. The adjustment bolt 28 screwed to the nut portion 29 is passed through the insertion hole 30 and the base 21 is sandwiched between the lock bolt 31 and the ring nut 32 at an arbitrary position of the adjustment bolt 28, so that the upper portion of the center rail 25 and the base 21 can be adjusted.

The carrier plate 20 is mounted on the center rail 25 via a guide roller 33. The guide roller 33 includes a roller 34 slidably engaged with the center rail 25 in a vertical direction,
And a shaft 35 having a base end fixed to the carrier plate 20. Therefore, since the shaft portion 35 is in a state where the angle is variable (the head can be freely swung) with respect to the roller 34 with the tip spherical portion 35a as the center, the carrier plate 20 eventually moves the guide roller 33 with respect to the center rail 25. The mounting structure is such that the degree of inclination can be changed in the vertical direction and the front-rear direction around the center.

The front end 36 and the rear end 37 of the base 21 are used as rails when the carrier plate 20 is moved up and down, and the upper side is rearward in accordance with the overall shape of the base 21. It has a curved shape. In addition, a guide flange 38 of a constant width is formed on the upper and lower portions of the rear end portion 37. The guide flange 38 is bent outwardly of the vehicle. The guide flange 38 is used as a rail in the front-rear direction Y and also serves to increase the overall rigidity of the base 21.

A first slider 39 is provided at a position corresponding to the rear end 37 of the carrier plate 20.
A second slider 40 is provided at a position corresponding to the front end 36. First slider 39 and second slider 40
Are frames 41 and 42 each having a U-shaped cross section, and a resin (polyacetal or the like) provided in the frames 41 and 42.
And sliding members 43 and 44 made of stainless steel. The sliding member 43 of the first slider 39 is formed with a pair of protrusions 43a for holding the rear end portion 37 in the door thickness direction X and a protrusion 43b for holding the guide flange 38 in the front-rear direction Y. I have. The sliding member 44 of the second slider 40 includes
Only a pair of protrusions 44a that sandwich the front end portion 36 in the door thickness direction X are formed, and the front-rear direction Y is free. The sliding members 43 and 44 may be outsert molded at the end of the carrier plate 20.

The first slider 39 and the second slider 4
0 is located at the same height position, and is located above the guide roller 33 by h. Therefore, the carrier plate 20 is supported at three points by the front and rear first and second sliders 39 and 40 and the guide roller 33.
Of the window panel 19 in the door thickness direction X, the inclination of the window panel 19 in the door thickness direction X can be changed. That is, since the mounting point 19a of the window panel 19 is integrally attached to the embossed portion 45 formed on the carrier plate 20 by the bolt 46 and the nut 47, if the position of the guide roller 33 is moved to the outside of the vehicle, The upper end of the window panel 19 attached to the carrier plate 20 falls down inside the vehicle, and when inverted, the upper end of the window panel 19 changes its angle to the outside of the vehicle. In this embodiment, the distance d between the upper part of the center rail 25 and the base 21 is increased so that the upper end thereof falls down to the inside of the vehicle by a predetermined angle as the window panel 19 rises.

A pulley 48,
A wire member 50 is provided between the upper and lower pulleys 48 and 49. The wire member 50 is moved by the rotation of a winding unit 52 driven by a motor 51 fixed to the base 21.
The wire member 50 between the upper and lower pulleys 48 and 49 is protected by an outer tube 53. Since a part of the wire member 50 is connected to the locking portion 54 of the carrier plate 20, the carrier plate 20 is pulled by the wire member 50 and moves up and down. The motor 51 is covered with a resin case for waterproofing.

The window panel elevating device 18 according to this embodiment has the above-described structure. Since the rail having the original shape is only the center rail 25, the number of parts is small, and the assembling work of the window panel elevating device 18 is performed. The number of man-hours is reduced and work becomes easier.

Further, since the base 21 itself is a press-formed product, the positional accuracy of the front end 36 and the rear end 37 used as a rail is perfect. Therefore, by moving the carrier plate 20 up and down using the front end portion 36 and the rear end portion 37 as rail portions, the carrier plate 20 is moved up and down.
Can be moved up and down accurately, and the mounting accuracy of the window panel 19 integrally attached to the carrier plate 20 is also improved.

Further, since the front end portion 36 and the rear end portion 37 of the base 21, which is a press-formed product having a fixed shape and high positional accuracy, are used as rails, the window panel 19 can be mounted. The only adjustment work that can affect the accuracy is the work of adjusting the position of the center rail 25, and the adjustment work is much easier than in the past. In particular, since the front end 36 without the guide flange 38 is free in the front-rear direction Y, the position adjustment of the center rail 25 in the front-rear direction Y may be performed with reference to the rear end 37 alone.

Further, since the front end portion 36 is in the free state as described above, the position of the carrier plate 20 depends on the positional relationship between the rear guide flange 38 and the center rail 25.
The rotational position in the front-rear direction Y about the guide roller 33 is determined. That is, when the guide flange 38 is set at a position away from the guide roller 33, the first slider 39 is pulled rearward to lower the position, so that the carrier plate 20 is moved clockwise A around the guide roller 33 (see FIG. 2). When the guide flange 38 is moved closer to the guide roller 33, the position of the first slider 39 is raised.
3 will be rotated in the counterclockwise direction B. In this manner, the rotational position of the carrier plate 20 (window panel 19) about the guide roller 33 is determined by the positional relationship between the center rail 25 and the guide flange 38, and the positional relationship between the two is applied to the door to be applied. Is designed in advance so that an optimal position can be obtained according to the shape of.

The sliding members 43 and 44 of the first slider 39 and the second slider 40 are formed by the projections 43a, 43b and 44a having a small contact area, respectively.
7. Since the carrier plate 20 comes into contact with the guide flange 38, the vertical sliding resistance of the carrier plate 20 is extremely small. That is, even if the carrier plate 20 rotates about the guide roller 33 as described above, or the inclination degree in the door thickness direction X changes, the contact area of each of the projections 43a, 43b, and 44a changes. Therefore, the sliding resistance does not increase.
In addition, the guide roller 33 itself also has a spherical portion 3 at the tip of the shaft portion 35.
Since the ball joint 5a is a kind of ball joint (free joint), even if the inclination of the carrier plate 20 is changed, the angle of the shaft 35 changes only in accordance therewith, so that there is a practical engagement relationship. There is no change in the relationship between the roller 34 and the center rail 25. Therefore, the sliding resistance between the guide roller 33 and the center rail 25 does not increase.

Further, since the wire member 50 moved by the motor 51 is connected to the carrier plate 20 and moved up and down, even if the inclination of the carrier plate 20 in the door thickness direction X changes as described above. Therefore, the vertical movement performance of the carrier plate 20 is not hindered.

In this embodiment, the upper portion of the center rail 25 can be moved toward and away from the base 21 by the adjuster bolt 28. On the contrary, the lower portion of the center rail 25 can be moved toward and away from the base 21. It may be free.

FIGS. 4 to 7 show a second embodiment of the present invention. In the base 55 according to this embodiment, a distance adjusting mechanism using the adjuster bolt 28 is omitted, and a rigid flange 57 is provided on a front end 56 of the base 55.
Are formed, and a guide flange 59 is formed on the rear end portion 58. Therefore, the overall rigidity of the base 55 is improved by the amount corresponding to the formation of the rigid flange 57 as compared with the previous embodiment.

The front end 56 on which the rigid flange 57 is formed is sandwiched in the door thickness direction X by a projection 61a provided on the sliding member 61 of the second slider 60, and slides vertically. Although it is movable, it is free in the front-rear direction Y. The protrusion 61a has a convex shape with the center in the vertical direction protruding (see FIG. 6), and the sliding area with respect to the front end portion 56 is small.

On the other hand, the first corresponding to the guide flange 59
A main sliding member 63 is provided in the frame 66 of the slider 62.
The main sliding member 63 is provided with a pair of projections 63a for holding the guide flange 59 in the front-rear direction Y. This projection 6
3a also has a convex shape with the center in the vertical direction protruding (see FIG. 7), and the sliding area with respect to the guide flange 59 is small. Also, a convex protrusion 64a is formed on the sub sliding member 64, and the rear end portion 58 is sandwiched between the protrusion 64a and the main sliding member 63 in the door thickness direction X. It is slidable in the vertical direction.

The main sliding member 63 of the first slider 62 has a shaft 6 fixed to the carrier plate 20.
The first slider 62 is mounted on the carrier plate 20 via the shaft 65. Since the tip 65a of the shaft 65 has a spherical portion, the shaft 65 is
, The angle can be freely changed in the front-rear direction Y and the vertical direction. Therefore, if the center rail 25
Even if there is an error in the position adjustment between the guide plate 59 and the guide flange 59, the shaft portion 65 changes its angle around the tip portion 65a, so that the vertical sliding resistance of the carrier plate 20 does not increase. . In addition, by changing the distance between the guide roller 33 and the guide flange 59 in the vertical direction, the carrier plate 20 is rotated clockwise or counterclockwise around the guide roller 33 with the rise of the carrier plate 20. Also in this case, since the distal end portion 65a of the shaft portion 65 is a free joint (ball joint) with respect to the first slider 62, smooth vertical movement can be performed. The other configuration and operation and effect are the same as those of the previous embodiment, and redundant description is omitted.

In each of the above embodiments, a sash-less door has been described as an example. However, the present invention can also be applied to a door having a sash portion integrated with the door. Further, the example in which the guide flanges 38 and 59 are formed on the rear ends 37 and 58 of the bases 21 and 55 has been described.
6, 56 may be formed.

[0039]

According to the vehicle window panel elevating device of the first aspect, each of the front end portion and the rear end portion of the base is used as a rail portion serving as a position reference in the door thickness direction of the carrier plate, In addition, since the guide flange can be used as a position reference in the front-rear direction, the conventional structure requires only one center rail, and the number of parts can be greatly reduced.
The number of assembling work steps is reduced, which is very advantageous in terms of workability.

Since the base is a press-formed product,
The shape is constant, and the positional accuracy of the front end and the rear end used as the rails is high. Therefore, the position of the carrier plate in the door thickness direction and the front-rear direction is determined based on the front end portion and the rear end portion having high position accuracy and the guide flange formed on one of the front end portion and the rear end portion. The mounting accuracy with respect to the base is increased, and as a result, the mounting accuracy of the window panel mounted on the carrier plate is improved.

Further, since the front end and the rear end of the base having a fixed shape and high positional accuracy are used as the rails, the installation adjustment of the window panel is as follows.
Only the adjustment of the center rail position is required, and the work of adjusting the installation of the window panel becomes very easy.

According to the second aspect of the present invention, the tip of the shaft fixed to the carrier plate is fitted to the first slider, and the shaft with respect to the first slider is centered on the tip.
