<Overall structure of wind regulator 1>
The overall configuration of the window regulator 1 of the present embodiment will be described with reference to FIGS. 1 to 3. 1 is a front view showing the wind regulator 1, FIG. 2 is a rear view showing the wind regulator 1, and FIG. 3 is a front view showing each drive position of the wind regulator 1.

The wind regulator 1 includes a lift arm (arm) 10, an equalizer arm (other components) 20, a lift arm bracket (guide rail, slidable member) 30, an equalizer arm bracket 40, and a drive unit 50. Have.

The lift arm 10 is composed of a long plate-shaped member extending in the longitudinal direction.

The tip end side (one end side) of the lift arm 10 is connected to the lift arm bracket 30 to which the window glass (not shown) is fixed, and supports the lift arm bracket 30. More specifically, a slider (sliding member, shoe) 12 is attached to the tip end side of the lift arm 10 via a roller pin (slider connecting member, sliding member connecting member) 11, and the slider 12 is a lift arm bracket. It is accommodated and guided by the guide (sliding portion, sliding groove) 31 of 30.

The base end side (the other end side) of the lift arm 10 is rotatably supported by the drive unit 50. More specifically, the drive unit 50 has a motor 51 and a sector gear 52 that is driven to rotate (rotate, swing) by the motor 51. The base end side of the lift arm 10 is configured to rotate integrally with the sector gear 52 as the drive unit 50 is driven (rotational drive of the sector gear 52 by the motor 51).

The equalizer arm 20 has a first arm 21 and a second arm 22. The first arm 21 and the second arm 22 are joined in a through hole 13 (described later in FIGS. 7, 8, 13 to 17) in the central portion (intermediate portion) in the longitudinal direction of the lift arm 10. The lift arm 10 and the equalizer arm 20 are pivotally attached in an X shape by joining the base end portions (root portions) of the first arm 21 and the second arm 22 so that their surfaces are in close contact with each other. The first arm 21 and the second arm 22 can be joined by any means such as caulking or welding.

The tip of the first arm 21 of the equalizer arm 20 is connected to the equalizer arm bracket 40. More specifically, a slider (shoe) 21S is attached to the tip of the first arm 21 of the equalizer arm 20, and the slider 21S is accommodated and guided by the guide 41 of the equalizer arm bracket 40.

The tip of the second arm 22 of the equalizer arm 20 is connected to the lift arm bracket 30. More specifically, a slider (shoe) 22S is attached to the tip of the second arm 22 of the equalizer arm 20, and the slider 22S is accommodated and guided by the guide 31 of the lift arm bracket 30.

As described above, the wind regulator 1 joins the first arm 21 of the equalizer arm 20 and the base end portions of the second arm 22 at the central portion of the lift arm 10 in the longitudinal direction, whereby the lift arm 10 and the equalizer arm 20 are joined. It is a so-called X-arm type wind regulator that is pivotally attached in an X shape. In the window regulator 1, when the lift arm 10 is rotated by the drive unit 50, the lift arm bracket 30 connected (supported) to the lift arm 10 and the wind glass fixed to the lift arm bracket 30 are raised and lowered (driven). .. As described above, the lift arm 10 is a component for raising and lowering (driving) the window glass. For example, in FIG. 3, each drive position of the wind regulator 1 is drawn, and corresponds to a fully open position, an intermediate opening position, and a fully closed position of the wind glass.

<Detailed structure and action of lift arm 10>
As a result of diligent research, the present inventor has found that in an arm-type wind regulator, there is room for improvement in the strength or durability of the lift arm when the lift arm is rotated to open and close the window glass. For example, if you open and close the window glass with the paper or seal attached to the surface of the window glass, the weatherstrip will entangle the paper or seal, and as a result, a twisting force will be applied to the tip side of the lift arm, and the lift arm will be lifted. The tip side may become a fragile part where torsional stress is concentrated. Further, if the edge on the tip end side of the lift arm to which a twisting force is applied is caught by the guide of the lift arm bracket, a force that buckles (compresses) the lift arm may act.

The wind regulator 1 of the present embodiment succeeds in improving the strength or durability of the lift arm 10 against torsional stress and buckling force (compressive force) by devising and optimizing the shape of the lift arm 10. is doing. Hereinafter, the detailed structure and action / effect of the lift arm 10 will be described.

[Lift arm 10 of the first aspect]
The lift arm 10 of the first aspect will be described with reference to FIGS. 7 to 14. 7 and 8 are perspective views and plan views showing the lift arm 10 of the first aspect. 9, FIG. 10, FIG. 11, FIG. 12, FIG. 13, and FIG. 14 show AA line, BB line, CC line, DD line, EE line, and FF of FIG. It is a cross-sectional view along a line.

As described above, the lift arm 10 is composed of a long plate-shaped member extending in the longitudinal direction, and has a tapered shape in which the length (width) in the lateral direction gradually decreases from the proximal end side to the distal end side. is doing. The base end side of the lift arm 10 corresponds to the side connected to the drive unit 50, and the tip end side of the lift arm 10 corresponds to the side connected to the lift arm bracket 30.

The lift arm 10 has a reference wall portion (bottom wall portion) 14 extending over a plane including the longitudinal direction and the lateral direction. The reference wall portion 14 does not have to be completely flat, and the first bead 15A, the second bead 15B, the third bead 15C, and the flange portion 18 (first portion 18A and second portion 18A and second) described later are not required. The portion 18B of the above may be a component having a reference surface on which the third portion 18C) is formed.

The lift arm 10 has a first bead 15A and a second bead 15B extending in the longitudinal direction of the lift arm 10 apart from each other in the lateral direction of the lift arm 10. The lift arm 10 has a third bead 15C connecting the first bead 15A and the second bead 15B on the distal end side in the longitudinal direction of the lift arm 10.

The first bead 15A and the second bead 15B extend so as to gradually approach each other toward the tip end side in the longitudinal direction of the lift arm 10. At the point where the first bead 15A and the second bead 15B are closest to each other, the tips of the first bead 15A and the second bead 15B are connected to each other by the third bead 15C. The third bead 15C has an R shape connecting the tips of the first bead 15A and the second bead 15B. The third bead 15C is formed from a portion where the tips of the first bead 15A and the second bead 15B start to bend (the portion where the R shape starts), and the first bead 15A and the third bead 15C are formed with the said portion as a boundary. The second bead 15B and the third bead 15C are partitioned.

Here, there is a degree of freedom in the modes of the first bead 15A, the second bead 15B, and the third bead 15C, and various design changes are possible. For example, the first bead 15A and the second bead 15B may extend completely parallel along the longitudinal direction of the lift arm 10. Further, the third bead 15C may connect the first bead 15A and the second bead 15B slightly in front of the tip end portion (the first bead 15A and the second bead 15B are the third bead 15C). It may protrude toward the tip side). It is an expression to include this aspect that the third bead 15C connects the first bead 15A and the second bead 15B on the "tip side" in the longitudinal direction of the lift arm 10. Further, the third bead 15C does not have to have a constant (uniform) R shape, and may have an angular shape and may connect the tips of the first bead 15A and the second bead 15B to each other. However, it is preferable that the third bead 15C has an R shape because good moldability can be obtained regardless of the material.

In this way, on the distal end side of the lift arm 10 in the longitudinal direction, the third bead 15C and the third bead 15C are connected so as to wrap around from the first bead 15A and the second bead 15B, and the third bead 15C and the first bead are connected. By receiving a load at the connection portion between the 15A and the second bead 15B, the strength or durability of the lift arm 10, particularly the strength or durability against torsional stress and buckling force (compressive force) can be improved ( It can prevent the occurrence of twisting and buckling (compression)).

By the way, in the prior art including Patent Document 1, since the pair of beads extending in the longitudinal direction are interrupted (divided), the vicinity of the tip portion of the pair of beads becomes a fragile portion where torsional stress is concentrated. , The strength or durability of the lift arm was insufficient.

At least one of the first bead 15A and the second bead 15B is an equalizer arm 20 (first arm 21, second arm 22) as another component related to the lift arm 10 in the longitudinal direction of the lift arm 10. Extends to. The lift arm 10 and the equalizer arm 20 rotate relative to each other with respect to the pivot portion as the wind regulator 1 is driven, so that the degree of overlap with each other changes. Therefore, by extending the first bead 15A and the second bead 15B of the lift arm 10 to the equalizer arm 20, the strength or durability of the lift arm 10 is improved regardless of the relative rotation position with the equalizer arm 20. There is. More specifically, the first bead 15A and the second bead 15B extend to the pivot portion of the lift arm 10 and the equalizer arm 20 with zero lap amount, or the pivot portion of the lift arm 10 and the equalizer arm 20. It enters and extends to a position where it wraps (overlaps) with the equalizer arm 20. In particular, by wrapping the first bead 15A and the second bead 15B with the equalizer arm 20 (entering the arc of the pivot portion), the strength or durability of the lift arm 10 can be improved. For example, the first bead 15A and the second bead 15B extend to the end edge (plate edge) of the equalizer arm 20 as a pivoting portion so that the amount of wrap is zero or wraps. In particular, in a state where the amount of overlap between the lift arm 10 and the equalizer arm 20 is the smallest (a state in which the angle formed by each other is approximately 90 °), the first bead 15A and the second bead 15B are equalizers as pivoting portions. It is preferable that the amount of wrap is zero or extends so as to wrap to the end edge (plate edge) of the arm 20. It should be noted that at least one of the first bead 15A and the second bead 15B is in the longitudinal direction of the lift arm 10 in front of the equalizer arm 20 as another component related to the lift arm 10, specifically, the lift arm. It may extend to the front of the pivotal portion of the 10 and the equalizer arm 20. Here, the front of the pivoted portion of the lift arm 10 and the equalizer arm 20 means, for example, a range from the end edge (plate edge) of the equalizer arm 20 as the pivoted portion to at least 50 mm. That is, the position of the end edge (plate edge) of the equalizer arm 20 as the pivoting portion is defined as 0 mm, the position 50 mm before the end edge (plate edge) is defined, and the first bead 15A and the second bead 15B extend. When the position of the end portion is defined as X mm, 0 <X <50 or 0 <X ≦ 50 can be satisfied.

The lift arm 10 has a seat surface 16 located on the tip side of the third bead 15C in the longitudinal direction of the lift arm 10. The seat surface 16 is for installing a roller pin (slider connecting member, sliding member connecting member) 11, and the roller pin 11 is rotatably supported by an installation hole provided in the center of the seat surface 16. Further, the slider 12 is attached via the roller pin 11, and the slider 12 is accommodated and guided by the guide 31 of the lift arm bracket 30. The seat surface 16 projects to the outside of the vehicle, which is the side of the slider 12 driven by the roller pin 11. The seat surface 16 functions as a reference surface for the roller pin 11 and the slider 12 as a mounting member.

The third bead 15C and the seat surface 16 are connected to each other by the connecting portion 17. More specifically, the third bead 15C projects to one side (inside the vehicle) of the lift arm 10 in the thickness direction, and the seat surface 16 projects to the other side (outside the vehicle) of the lift arm 10 in the thickness direction. It stands out. The third bead 15C and the seat surface 16 are connected to each other by a connecting portion 17 so as to straddle the thickness direction of the lift arm 10. In the illustrated embodiment, the connecting portion 17 constitutes a connecting surface that connects the rising portion of the third bead 15C and the rising portion of the seat surface 16 in a plane. This plane connection surface does not completely coincide with the thickness direction of the lift arm 10, and constitutes an inclined connection surface that is slightly inclined with respect to the thickness direction of the lift arm 10.

The third bead 15C and the seat surface 16 (roller pin 11) are provided so as not to wrap with each other when viewed in the longitudinal direction of the lift arm 10 (the connecting portion 17 is provided in the longitudinal direction of the lift arm 10). They are separated from each other through).

By providing a seat surface 16 located on the tip side of the third bead 15C in the longitudinal direction of the lift arm 10 and receiving a load on the seat surface 16, the strength or durability of the lift arm 10, especially torsional stress and buckling, is provided. It is possible to improve the strength or durability against force (compressive force) (it is possible to prevent the occurrence of twisting and buckling (compression)).

Moreover, by reversing the protruding directions of the third bead 15C and the seat surface 16 and connecting the third bead 15C and the seat surface 16 via the connecting portion 17, the third bead 15C and the seat surface 16 straddle in the thickness direction of the lift arm 10. By receiving a load at the connection portion 17, the strength or durability of the lift arm 10, particularly the strength or durability against torsional stress and buckling force (compressive force) can be further improved (twisting or buckling (twisting or buckling (compression force)). It is possible to prevent the occurrence of compression)).

It is also possible to set the protruding direction of the third bead 15C and the seat surface 16 to be the same direction and omit the connecting portion 17 connecting the third bead 15C and the seat surface 16.

When the lift arm 10 is viewed in a plan view, the outer circumference of the lift arm 10 is the outer peripheral end (outer peripheral edge) of the reference wall portion (bottom wall portion) 14 and the tip side where the seat surface 16 protrudes from the reference wall portion 14. , Defined by the outer peripheral edge (outer peripheral edge) of the seat surface 16.

The lift arm 10 has a flange portion 18 that rises in the thickness direction of the lift arm 10 on the outer periphery of the lift arm 10 (the outer peripheral end of the reference wall portion 14 and / or the seat surface 16). The flange portion 18 rises on one side (inside the vehicle) of the lift arm 10 in the thickness direction (protrudes in the same direction as the first bead 15A, the second bead 15B, and the third bead 15C).

The flange portion 18 has a first portion 18A and a second portion 18B extending in the longitudinal direction of the lift arm 10 apart from each other in the lateral direction of the lift arm 10. The flange portion 18 has a third portion 18C connecting the first portion 18A and the second portion 18B on the distal end side of the lift arm 10 in the longitudinal direction.

The first portion 18A and the second portion 18B are extended so as to gradually approach toward the tip end side in the longitudinal direction of the lift arm 10 according to the shape of the lift arm 10. At the point where the first portion 18A and the second portion 18B are closest to each other, the tips of the first portion 18A and the second portion 18B are connected to each other by the third portion 18C. The third portion 18C has an R shape that connects the tip portions of the first portion 18A and the second portion 18B according to the shape of the seat surface 16. The third portion 18C is formed from a portion where the tips of the first portion 18A and the second portion 18B begin to bend (the portion where the R shape begins), and the first portion 18A and the third portion 18C are formed with the said portion as a boundary. The second portion 18B and the third portion 18C are partitioned.

The first portion 18A and the second portion 18B form a gradual side portion whose height gradually decreases from the tip end side to the base end side of the lift arm 10. For example, as shown in FIGS. 11 and 12, the heights of the first portion 18A and the second portion 18B on the distal end side of the lift arm 10 (FIG. 11) are the first heights on the proximal end side of the lift arm 10. It is larger than the height of the portion 18A and the second portion 18B (FIG. 12).

At least one of the first portion 18A and the second portion 18B is an equalizer arm 20 (first arm 21, second arm 22) as another component related to the lift arm 10 in the longitudinal direction of the lift arm 10. Extends to. The lift arm 10 and the equalizer arm 20 rotate relative to each other with respect to the pivot portion as the wind regulator 1 is driven, so that the degree of overlap with each other changes. Therefore, by extending the first portion 18A and the second portion 18B of the lift arm 10 to the equalizer arm 20, the strength or durability of the lift arm 10 is improved regardless of the relative rotation position with the equalizer arm 20. There is. More specifically, the first portion 18A and the second portion 18B extend to the pivot portion of the lift arm 10 and the equalizer arm 20 with zero lap amount, or the pivot portion of the lift arm 10 and the equalizer arm 20. It enters and extends to a position where it wraps (overlaps) with the equalizer arm 20. In particular, by wrapping the first portion 18A and the second portion 18B with the equalizer arm 20 (entering the arc of the pivot portion), the strength or durability of the lift arm 10 can be improved. For example, the first portion 18A and the second portion 18B extend to the end edge (plate edge) of the equalizer arm 20 as a pivoting portion so that the amount of wrap is zero or wraps. In particular, in a state where the amount of overlap between the lift arm 10 and the equalizer arm 20 is the smallest (a state in which the angle formed by each other is approximately 90 °), the first portion 18A and the second portion 18B are equalizers as pivoting portions. It is preferable that the amount of wrap is zero or extends so as to wrap to the end edge (plate edge) of the arm 20. It should be noted that at least one of the first portion 18A and the second portion 18B is in the longitudinal direction of the lift arm 10 in front of the equalizer arm 20 as another component related to the lift arm 10, specifically, the lift arm. It may extend to the front of the pivotal portion of 10 and the equalizer arm 20. Here, the front of the pivoted portion of the lift arm 10 and the equalizer arm 20 means, for example, a range from the end edge (plate edge) of the equalizer arm 20 as the pivoted portion to at least 50 mm. That is, the position of the end edge (plate edge) of the equalizer arm 20 as the pivoting portion is defined as 0 mm, the position 50 mm before the position is defined, and the first portion 18A and the second portion 18B extend. When the position of the end portion is defined as Y mm, 0 <Y <50 or 0 <Y ≦ 50 can be satisfied.

In the flange portion 18, the first portion 18A and the second portion 18B are connected by a third portion 18C (connected by the tip of the lift arm 10), and at least the longitudinal tip of the lift arm 10 is connected. The slider (sliding member) 12 provided on the side is located within the width A of the lift arm bracket (sliding member) 30 on which the slider (sliding member) 12 slides. Here, the width A of the lift arm bracket 30 means not only the width of the guide 31 but also the entire width of the lift arm bracket 30 including the guide 31 (not only the flange portion known to the guide 31 but also a flat surface). It means the width including the part). In FIGS. 1 to 3, the width A of the lift arm bracket 30 defined as described above is drawn with a reference numeral.

In this way, by locating the flange portion 18 at least within the width A of the lift arm bracket 30 on which the slider 12 slides, for example, when the third bead 15C receives the twisting force, it is outside. It is possible to improve the strength or durability of the lift arm 10 by receiving the twisting force applied from (it is possible to prevent the occurrence of twisting). Further, it is possible to improve the strength or durability of the lift arm 10 against the buckling force (compressive force).

Further, at least a part (for example, the tip portion) of the third portion 18C of the flange portion 18 is located at the tip portion in the longitudinal direction of the lift arm 10, and is located within the range of the guide 31 of the lift arm bracket 30. ing. Further, at least a part of the third portion 18C of the flange portion 18 (for example, a certain region including the tip portion) is located at least a part of the corner portion of the seat surface 16 located on the tip side in the longitudinal direction of the lift arm 10. is doing. This makes it possible to improve the strength or durability of the lift arm 10 against the torsional stress and buckling force (compressive force).

Further, the flange portion 18 has R surface portions 18AR, 18BR, and 18CR located on the outer periphery of the lift arm 10 and rising in a rounded manner from a surface connected to the flange portion 18 within the range of the width A of the slider 12. .. The first portion 18A has an R surface portion 18AR located on the outer periphery of the lift arm 10 and rising from the reference wall portion 14 connected to the flange portion 18 in a rounded manner within the range of the width A of the slider 12. 11 and 12). The second portion 18B has an R surface portion 18BR that is located on the outer periphery of the lift arm 10 and rises roundly from the reference wall portion 14 that is connected to the flange portion 18 within the range of the width A of the slider 12. 11 and 12). The third portion 18C has a reference wall portion 14 located on the outer periphery of the lift arm 10 and connected to the flange portion 18 and an R surface portion 18CR that rises roundly from the seat surface 16 within the range of the width A of the slider 12. (Figs. 9 and 10).

By providing such R surface portions 18AR, 18BR, 18CR, it is possible to further improve the strength or durability of the lift arm 10 against the torsional stress and buckling force (compressive force). Further, it is possible to prevent the flange portion 18 from interfering with (being caught by) other components (for example, the equalizer arm 20) when the wind regulator 1 is driven.

The lift arm 10 has a matching portion 19 extending further toward the tip side from the tip end portion in the longitudinal direction of the lift arm 10. More specifically, the matching portion 19 is bent after further rising from the tip portion (third portion 18C) of the flange portion 18, and further extends toward the tip side. The matching portion 19 is a portion for connecting to another material at the time of molding the lift arm 10, and may have a minimum length for being bent. By providing the matching portion 19, the length of the lift arm 10 on the tip end side can be increased.

[Lift arm 10 of the second aspect]
The lift arm 10 of the second aspect will be described with reference to FIGS. 4 to 6 and 15 to 17. 4, 5 and 6 are enlarged views of the IV part, the V part and the VI part of FIG. 15 and 16 are perspective views and plan views showing the lift arm 10 of the second aspect. FIG. 17 is a cross-sectional view taken along the line GG of FIG.

In the lift arm 10 of the first aspect, in the flange portion 18, the first portion 18A and the second portion 18B are connected by the third portion 18C (connected by the tip of the lift arm 10). On the other hand, in the lift arm 10 of the second aspect, a recess 18D is formed in which the third portion 18C is interrupted at the tip end portion of the lift arm 10. A matching portion 19 is formed so as to protrude from the inside of the recess 18D.

Also in the lift arm 10 of the second aspect, by positioning the flange portion 18 at least within the width A of the lift arm bracket 30 on which the slider 12 slides, for example, a twisting force is applied by the third bead 15C. It is possible to improve the strength or durability of the lift arm 10 by receiving the twisting force applied from the outside when it is received (it is possible to prevent the occurrence of twisting). Further, it is possible to improve the strength or durability of the lift arm 10 against the buckling force (compressive force).

In the above embodiment, the lift arm 10 includes the first bead 15A, the second bead 15B, the third bead 15C, and the flange portion 18 (the first portion 18A and the second portion 18B are third. The case where the portion 18C) is provided is illustrated and described. However, in the wind regulator 1 of the present embodiment, the first bead 15A, the second bead 15B, and the third bead 15C are provided, and the flange portion 18 (the first portion 18A and the second portion 18B are third. 18C) is omitted, or a flange portion 18 (a first portion 18A and a second portion 18B are a third portion 18C) is provided to provide a first bead 15A, a second bead 15B, and a second bead. It is also possible to omit the bead 15C of 3. In any aspect, the strength or durability of the lift arm 10 against the torsional stress and buckling force (compressive force) can be improved.

In the above embodiment, the lift arm 10 and the equalizer arm 20 are formed in an X shape by joining the base ends of the first arm 21 and the second arm 22 of the equalizer arm 20 at the central portion in the longitudinal direction of the lift arm 10. The so-called X-arm type wind regulator 1 pivotally attached to the above was illustrated and described. However, the wind regulator 1 of the present embodiment can also be applied to a so-called single arm type wind regulator in which the equalizer arm 20 is omitted and only the lift arm 10 is used.

In the above embodiment, the power type (motor type) wind regulator 1 in which the lift arm 10 is rotated by the drive unit 50 has been illustrated and described. However, the wind regulator 1 of the present embodiment can be applied not to the drive unit 50 but also to a manual type (manual type) wind regulator.

In the above embodiments, the equalizer arm 20 has been exemplified as another component related to the lift arm 10, but the other components related to the lift arm 10 include various members and parts other than the equalizer arm 20. It may be a site or the like.
