Abstract

PROBLEM TO BE SOLVED: To provide a structure for easily imparting or increasing wire tension in a wire drum type window regulator.SOLUTION: A wire passage between a wire drum 7 and a wire guide 9 is extended by rotating the wire guide 9. Thus, when a plane shape of the wire guide 9 for winding a wire 5 around a peripheral surface is rotated around a rotary shaft orthogonal to its plane, it is formed in a shape of becoming longer after rotation than before the rotation in the length of the wire 5 contacting with the peripheral surface. The wire 5 is temporarily fastened to this by providing a wire temporary fastening part 21 in the wire guide 9, and the wire guide 9 is rotated by using force of pulling the wire 5 wound around the wire guide 9 by the wire drum 7. When the temporary fastening part 21 comes to slip out to the outside from the wire passage by rotating the wire guide 9, the wire 5 held by the temporary fastening part 21 is re;eased from the temporary fastening part 21 by component force of the wire tension.

Description

  The present invention relates to a wire drum type window regulator used for opening and closing a window glass in a vehicle window.

  A wire drum type window regulator has a structure in which a window glass is supported by a glass support member (carrier) attached to the wire, and the wire is passed between a wire drum arranged inside the door panel and a wire guide. In general, the window glass is opened and closed by reciprocating the wire with a wire drum.

In such a window regulator, if the wire tension is not sufficient, vertical fluctuation (judder) is generated in the window glass during ascent and descent. In particular, the so-called railless type without the rail that guides the glass support member is completed as a regulator while assembling the member into the door panel, so it is difficult to incorporate it into the door panel after applying tension to the wire in advance, It is difficult to apply sufficient tension. In addition, since the guide rail is not provided, the movement of the glass support member is likely to be unstable as compared with the case where the glass support member is guided by the guide rail. For this reason, judder is likely to occur not only at start-up but also during ascent and descent.
In order to suppress such judder with a railless type window regulator, it is necessary to increase the tension of the wire after the wire is once routed.

Conventionally, various window regulators have been proposed that have means for adjusting the tension of a wire after the wire is once routed.
In Patent Document 1, the wire ends (52) of the wires (41, 42) on both sides are slidably attached to the housing (50) via springs (57), and a stopper is provided between the wire ends on both sides. The wire is slackened by compressing the coil spring to both sides through the means (101), and after the wiring, the stopper means (101) is removed to remove the slack of the wire, and tension is applied to the wire by the elasticity of the spring. The configuration is described.

  Patent Document 2 is provided with two arm portions (13, 14) that apply lateral elastic deformation with a torsion coil spring (12) to the wires (5, 6) extending in the tangential direction of the wire drum (8). In addition, a slack absorbing mechanism for a window regulator wire is described. 10 and 11, as an example of the prior art, eccentric rollers (81, 82) are rotatably supported and urged in a direction to absorb the slack of the wire by the elasticity of the torsion coil springs (85, 86). Although the configuration is described, it is a prevention of sagging and not an increase in wire tension.

  In Patent Document 3, a wire (71) is connected to four guide members including first and second upper guide members (81) and (91) and first and second lower guide members (83) and (93). And a rotation stopping means for allowing the first lower guide member (83) to move in a direction in which the wire (71) is tensioned and prohibiting the first lower guide member (83) from rotating. The first lower guide member (83) is formed along a direction in which tension is applied to the wire (71). When a screw fastening force is applied, the first lower guide member (83) is applied in the direction in which tension is applied to the wire (71). A window regulator having an inclined surface (83c) that generates a force to move is described. In this regulator, the wire (71) is once wrapped around the four guide members to remove the slack, and then the first lower guide member (83) is slid along the inclined surface (83c), and the wire ( 71).

JP 2012-57425 A JP-A-3-172488 JP 2012-237122 A

In the technique of Patent Document 1, a wire is loosened once using a stopper means to facilitate the wiring, and after the wiring, the wire is tensioned by a biasing means such as a spring to give the wire a tension. However, the elasticity of the spring is considered to be sufficient to eliminate the slack of the wired wires, and it is not considered that the above-mentioned judder phenomenon is suppressed.
The technique of Patent Document 2 is for applying tension to the wire for the window regulator, but it is also only capable of absorbing the slack of the wire. In addition, the number of parts increases, and installation work takes time.

In the window regulator disclosed in Patent Document 3, the slider (205) is pressed against the inclined surface (83c) of the first lower guide member (83) by tightening the bolt (203), and the first lower guide member is utilized by using the sliding due to the component force at that time. (83) is slid to increase the tension of the wire (71). However, this is to move the first lower guide member (83) linearly in the axial direction with respect to the first upper guide member (81), that is, two wires on both sides of the first lower guide member (83), that is, Since the wire going to the first upper guide member (81) and the wire coming from the second upper guide (91) (one wire that rotates the first lower guide member) must be pulled directly in the axial direction, A large force is required for the movement, and an operation of strongly tightening the bolt (203) is necessary.
The problem to be solved by the present invention is that, in a wire drum type window regulator, wiring is performed easily with a slack at the beginning, and after the slack is removed, the wire drum is automatically driven when the wire drum is driven. A window regulator capable of easily and surely enhancing the above is provided.

The following technical concept is adopted in a window regulator for a vehicle provided with a wire drum for reciprocating a wire, a wire guide for rotating the wire path, and a wire wound around the wire guide.
At least one of the wire guides is incorporated into a wire tension increasing device, and the wire guide has a flat plate shape around which a wire is wound, and a rotation axis in a direction perpendicular to the plane and a rotated position are It is assumed that after the locking portion and the regulator assembly to be maintained between the fixed portion of the regulator are attached to the door panel, a wire temporary fixing portion is provided on the peripheral surface on the side where the wire is first drawn out by the wire drum. It is assumed that the temporary fixing portion is released by the component force due to the tension of the wire that is separated from the peripheral surface of the wire guide as the wire guide rotates.

The wire guide has a shape in which the length of the wire wound around and in contact with the wire guide is longer after the rotation than before the rotation due to the rotation of the wire guide about the rotation axis.
For example, as shown in FIG. 4, the part where the wire hangs consists of a semicircular part, a linear part with one end connected to this, and an arc part, and the wire hangs on the semicircular part before rotation. Is formed in a shape in which the total length becomes longer after the rotation than before the rotation by hanging on a part of the semicircular portion, the linear portion and the arc portion.
Or, when the peripheral surface of the wire guide is divided into four quadrants around the rotation axis, such as a combination of a semicircle and an ellipse, the peripheral surfaces in adjacent quadrants have different lengths, As described above, the wire path length after the wire guide is rotated more than before the wire guide is rotated, such as by arranging the rotation shaft at the eccentric position of the flat plate shape, which is symmetric in both the left and right directions. Can be lengthened.

The wire tension is increased by pulling the wire stretched on the wire guide by holding it in the wire temporary fixing part provided on the wire guide and rotating the wire guide. It is preferable to provide a stopper for restricting the amount and a locking means (such as a lance) for maintaining the rotational position.
Additional configurations of the solution will be described in the embodiments.

  According to the present invention, in the wire tension increasing device, since the wire guide is rotated about the rotation axis by the wire drum via the wire, manual operation for rotating the wire guide is not required, and the regulator is used at a vehicle assembly factory or the like. The installation work can be simplified. That is, after the wire is routed between the wire guide and the wire drum to remove the slack, the wire guide is automatically rotated only by driving the wire drum in a predetermined direction, thereby increasing the tension of the wire. Further, since the wire guide rotates with a moment about the rotation axis, the operation of increasing the tension of the wire is smoother than that in which the wire guide is moved linearly.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[1] Overall Configuration A window regulator 1 (FIG. 1, hereinafter referred to as regulator 1) is mounted inside a vehicle door panel 2 (consisting of an inner panel 2a and an outer panel 2b and having a space between both panels). The regulator 1 includes a wire tension increasing device 3, a glass support member 4, a wire 5, a base plate 6, a wire drum 7 and a driving device 8, and these are assembled into an assembly factory as an assembly.
The wire tension increasing device 3 and the base plate 6 are a device and a member fixed to the inner panel 2a, and are arranged inside the door panel 2 with an interval in the vertical direction. The wire drum 7 and the driving device 8 are attached to the base plate 6.

Then, the wire 5 is wound around the wire guide 9 of the wire tension increasing device 3 and the wire drum 7 in a railless manner to form a wire path. The wire 5 is composed of two wires, a wire 5b for raising from the glass support member 4 to the lower wire drum 7 by rolling the wire guide 9 and a wire 5a for lowering from the wire drum 7 to the glass supporting member 4. This is a generic term for wires.
The descending wire 5a and the ascending wire 5b are reciprocally moved back and forth by driving the wire drum 7.
Then, the ascending wire 5b and the descending wire 5a are attached to the glass support member 4.
Therefore, when the drive device 8 drives and rotates the wire drum 7, the window glass supported by the glass support member 4 moves up and down, and the vehicle window is opened and closed.

[2] Wire tension increasing device The wire tension increasing device 3 includes the wire guide 9, the bracket 10 (FIG. 2), the bolt 11 and the nut 12 (FIG. 2). The wire guide 9 has a flat plate shape around which the wire 5 is wound. The wire guide 9 is assembled to the bracket 10 and can rotate within a set range with a rotation axis (collar portion 13) provided by the bracket 10 as an axis. it can.
The bracket 10 is a member that is non-rotatably assembled to the inner panel 2a, and serves as a fixed portion (vehicle side portion) of the regulator 1.

[2-1] Wire Guide The outer shape of the wire guide 9 (the shape formed by the peripheral surface) is such that the wire path length of the wire 5 wound around the wire guide 9 is determined by the rotation of the wire guide 9 about the rotation axis. The shape after the rotation is longer than that before the rotation.
That is, a straight portion 15 (first straight portion 15) extending from one end of the diameter of the semicircular portion 14 at a right angle to the opposite side of the semicircular portion 14, and a semicircular portion 14 at a right angle from the other end of the diameter. The second straight line portion 17 and the circular arc portion 16 extending on the opposite side of the first straight line portion 17, and the tip of the line connecting the second straight line portion 17 and the circular arc portion 16 is connected to the first straight line portion 18 with the first straight line portion 18. The shape is connected to the straight portion 15.
The third straight portion 18 may not be a straight line.

The wire guide 9 is made of a hard synthetic resin in which the main body portion 9a has a thickness (t) that is sufficiently larger than the diameter of the wire 5 as shown in FIG. Has a circumferential surface 19 of width (t). A wire groove 20 is formed on the peripheral surface 19.
In FIG. 2, reference numeral 9 b denotes a collar through hole, which is a portion through which the collar portion 13 penetrates the wire guide 9, and an inner opening portion is enlarged so as to increase in diameter to form a step surface 9 c. The collar through-hole 9b is formed so that the center coincides with the center of the circle forming the semicircular portion. The collar portion 13 is slightly longer than the thickness of the wire guide 9.

Therefore, when the wire 5 is hooked on the peripheral surface 19 of the semicircular portion 14 of the wire guide 9 as shown in FIG. 5 comes into contact with the second straight portion 17, and the wire guide 9 hangs on a part of the semicircular portion and the second straight portion 17 and the arc portion 16 after the rotation, so that the total length of the wire guide 9 is increased. Becomes longer after the rotation than before the rotation.
Here, when it is necessary to increase the tension of the wire 5 by 60 N or more in order to suppress judder of the window glass, if the elongation of the wire 5 is 30 N / mm, the wire guide 9 and the wire drum 7 are After the wire 5 is routed with almost no slack, the wire guide 9 and the wire drum 7 may be pulled by 2 mm or more on the wire guide 9 side.

  In other words, the path length of the wire 5 may be increased by 4 mm, but this may be achieved by the portion hanging on the semicircular portion 14, the second linear portion 17 and the arc portion 16. For this purpose, if the diameter of the semicircular portion 14 is 40 mm, the wire 5 is in contact with the wire guide 9 when the wire 5 is hung on the peripheral surface of the semicircular portion 14 as shown in FIG. Since the length is 62.8 mm, it is rotated about 45 ° counterclockwise from this state as shown in FIG. 4B to achieve 66.8 mm. In other words, the portion of the second straight line portion 17 and the circular arc portion 16 may have a size of 4 mm (arc portion 3/4 × 62.8 = 47.1 mm + second straight portion 4 mm + arc portion 1/4 × 62). .8 = 15.7 mm).

[2-2] Wire Temporary Fixing Part A wire temporary fixing part 21 (hereinafter referred to as temporary fixing part 21) is provided on the first linear portion 15 on the peripheral surface 19 of the wire guide 9. In this embodiment, the wire guide 9 is provided integrally with the main body portion 9a. The wire temporary fixing portion 21 is a wedge structure portion made of a hard synthetic resin having flexibility, and includes a receiving portion 22 and a movable wedge member 23 as shown in FIG.
The receiving portion 22 has a rectangular frame shape, and an inner surface 24a of the outer wall 24 near the main body portion 9a and an inner surface 25a of the inner wall 25 near the main body portion 9a are opposed to each other. A narrow guide space 26 is formed. One of the rear wall 27 and the front wall 28 with respect to the outer wall 24 and the inner wall 25 (the rear wall 27) is a part of the main body portion 9a, and the other opposing wall (the front wall 28) An opening 29 is formed at the center and is separated in the inner and outer directions. Further, spaces 24b and 25b are formed between the front wall 28 and the inner surfaces 24a and 25a, respectively, inside the frame shape constituting the receiving portion 22 rather than the opening 29 (FIG. 9A).

  Two movable wedge members 23 are formed such that a pair of wedge members 23a face each other symmetrically, and as a whole, a wedge is formed with a thick upper portion and a thin lower portion. Each wedge member 23a has a shallow wire groove 30 in the vertical direction on the opposing surface. Further, stopper ridges 31 are respectively provided on the side closest to the main body portion 9a and on the side farthest from the facing surface. The stopper protrusions 31 are respectively fitted in stopper grooves 32 provided on the main body portion 9a side of the inner and outer walls 24, 25 so that the wedge member 23a does not move toward the front wall 28.

Each of the pair of wedge members 23 a is individually formed integrally with a part of the upper end surface being connected to the upper surface of the outer wall 24 and the upper surface of the inner wall 25 by a hinge 33. That is, at the beginning of molding, the wedge member 23a is disposed in an inverted state on the upper surface of the outer wall 24 and the upper surface of the inner wall 25 (FIG. 6A).
After molding, the wedge member 23a is bent from both sides of the hinge 33 toward the guide space 26 of the receiving portion 22 using the hinge 33 and is stored in the guide space 26 (FIG. 6B). In the guide space 26, the wedge member 23 a contacts the guide surfaces 24 a and 25 a of the outer wall 24 and the inner wall 25. However, a space slightly narrower than the diameter of the wire 5 exists between the opposing surfaces of the wedge members 23a on both sides as long as it is not pushed downward strongly.

[3] Bracket The bracket 10 (FIGS. 2 and 3) is formed in a circular shape slightly larger than the wire guide 9, and includes a wire presser 34, the collar portion 13 and the bolt through hole 35.
The wire presser 34 has a length that extends from the upper end of the bracket 10 toward the inner panel 2a and has a tip that penetrates the inner panel 2a (FIG. 10). A square hole 36 for fitting the head of the bolt 11 is formed around the bolt through hole on the outer surface of the bracket 10.
In this embodiment, a stopper 37 and a lance 38 are provided on the inner surface of the bracket 10. The stopper 37 is a position where the third linear portion 18 (FIG. 4) which is the lower side of the wire guide 9 abuts at the rotation end position of the wire guide 9, and the lance 38 is an engagement provided on the wire guide 9 at the rotation end position. It is provided at a position that engages with the groove 41.
Further, near the inner end of the collar portion 13, an arcuate engagement strip 13 a is formed to protrude from the outer peripheral surface, and a groove 13 b is formed adjacent to the outer side. The engagement strips 13 a and the grooves 13 b are paired, and a pair or a plurality of pairs are formed on the outer peripheral surface of the collar portion 13.

[4] Assembly First, the parts of the wire tension increasing device 3 are assembled as follows.
The wire guide 9 and the bracket 10 are combined by passing the collar portion 13 of the bracket 10 through the collar through hole 9b of the wire guide 9. At the time of penetrating, the engaging strip 13a of the collar portion 13 is forcibly pushed into the collar through hole 9b, but the engaging strip 13a is elastically deformed so as to rotate toward the groove 13b. It can be inserted into the hole 9b. When the inner end side of the collar portion 13 reaches the enlarged opening in the inner opening portion of the collar through hole 9b, the engaging strip 13a is elastically returned to the original state and engaged with the step surface 9c. That is, the wire guide 9 is not dropped from the bracket 10.
The bolt 11 is passed through the bolt through hole 35 of the bracket 10, and its head is press-fitted into a square hole 36 that is formed at the outer end of the bolt through hole 35 and enlarged on the outer surface of the bracket 10.
Accordingly, the bolt 11 is also set integrally with the bracket 10, and the wire tension increasing device 3 (the wire guide 9, the bracket 10 and the bolt 11 and the nut 12) can be handled as one set. It will not drop off.

Then, the wire 5 is routed between the wire tension increasing device 3 and the wire drum 7, the glass support member 4 is attached to the wire 5, and the regulator plate is assembled together with the base plate 6, the wire drum 7 and the driving device 8.
At this time, the wire guide 9 is in a state in which the first and second straight portions 15 and 17 are perpendicular to each other and the wire 5 is in contact with only the semicircular portion of the wire guide 9, and the temporary fixing portion of the wire guide 9 21 holds the wire. That is, the ascending wire 5b that rotates the wire guide 9 is held in a state of being slightly pressed between the wire grooves 30 of the wedge member 23a facing the temporary fixing portion 21 (FIG. 9A).

[5] Attachment to vehicle The regulator assembly is attached to the door panel 2 of the vehicle in a vehicle assembly factory.
In mounting, a bolt through hole 39 through which the tip of the bolt 11 passes and a wire press through hole 40 (FIG. 10) through which the tip of the wire presser 34 passes are formed in the inner panel 2a in advance. The bolt 11 and the tip of the wire retainer 34 are passed through them, and then the nut 12 is screwed onto the tip of the bolt 11. Then, the nut 12 is tightened to fix the wire tension increasing device 3 to the inner panel 2a. In this operation, the head of the bolt is fitted into a square hole 36 formed on the outer side surface of the bracket 10 and is prevented from rotating, so that there is no trouble due to co-rotation.
At this time, even if the nut 12 is tightened strongly, the collar portion 13 is longer than the thickness of the wire guide 9 as described above, so that the wire guide 9 is not sandwiched between the inner panel 2a and the bracket 10 and cannot be rotated (see FIG. 10). The bracket 10 is fixed without rotating because the tip of the wire retainer 34 engages with the wire retainer through hole 40 of the inner panel 2a, and becomes a member (fixing member) on the vehicle body side.

[5-1] Enhancement of wire tension When the slack of the wire 5 is eliminated and the preparation is completed, the wire drum 7 is driven in a predetermined direction. The predetermined direction is a direction in which the ascending wire 5b held by the temporary fixing portion 21 of the wire guide 9 is pulled.
When the lifting wire 5b is pulled, the wedge members 23a and 23a of the temporary fixing portion 21 are pulled downward by friction (FIG. 9B), and the lifting wire 5b is strongly gripped, so that the wire guide 9 pivots on the collar portion 13. 4A is rotated to the left in FIG. 4A to shift from the state of FIG. 5 to the state of FIG. During this time, the second linear portion 17 and the arc portion 16 come into contact with the ascending wire 5b. Further, when the wire guide 9 is rotated, the tension of the wire 5 is increased, and the temporary fixing portion 21 is connected to the wedge member 23 opposed to the temporary fixing portion 21 in FIG. On the other hand, the forward component force based on the wire tension acts strongly. Then, when rotated about 45 °, the opposing wedge member 23a is forcibly deformed (FIG. 9C), and the ascending wire 5b comes out of these opposing surfaces, and the front wall of the outer wall 24 and the inner wall 25. The ascending wire 5b is opened from the opening 29 provided in the center of 28 (FIG. 8).

At this time, in this embodiment, as described above, the path length of the wire 5 is increased by about 4 mm, and the wire path between the wire drum 7 and the wire guide 9 is stretched by 2 mm. In this state, a tension of about 60 N is enhanced.
Further, this state is a position where the rotation of the target wire guide 9 is completed. In order to prevent the wire guide 9 from rotating in reverse, in this state, the locking groove 41 provided in the wire guide 9 is provided on the bracket 10. Beyond the lance 38, it is engaged in the return direction. On the other hand, when the lifting wire 5b is not released by the wedge member 23a even though the lifting wire is pulled for some reason, the linear portion is placed on the stopper 37 located on the opposite side of the lance 38. The opposite side of 18 collides, forcibly releasing the holding state of the temporary fixing portion 21 and the ascending wire 5b, thereby eliminating the predicted inconvenience.

As described above, after the regulator assembly is attached to the inside of the door panel 2, the required wire tension is increased only by rotating the wire drum 7 in a predetermined direction as a trial run, and the attaching operation is simplified. Further, since the wire tension is increased by the magnitude of the moment related to the rotation of the wire guide 9 around the collar portion 13, the operation is light and smooth.
Since the wire guide 9, the bracket 10, the bolt 11 and the nut 12 constituting the wire tension increasing device 3 are gathered together as one set without dropping off, it is easy to handle when attaching to the door panel.
In the above embodiment, the flat shape of the wire guide 9 has the semicircular portion 14, the first and second straight portions 15 and 17, and the arc portion 16. If it can increase, it will not restrict to this.

[6] Example 2
For example, as shown in FIG. 11, the upper half is a circle (semicircle) and the lower half is an ellipse (semi-ellipse) with respect to the peripheral surface, and a form in which the diameter of the circle is coincident with the minor axis of the ellipse can be taken up. . When the planar shape of the wire guide 9 with the collar portion 13 as the rotation center is divided into quadrants I to IV, when rotated 90 degrees clockwise from the state of FIG. As for the wire length of the wire wound around the wire guide 9, what was wound in the first and second quadrants was wound in the second and third quadrants. The wire path length becomes longer due to the difference from the elliptical circumference which is longer than the circumference. As a result, the tension is increased in the wire 5 stretched between the wire guides and between the wire drums without slack. Since the wire 5 is held by the temporary fixing portion 21, the wire guide 9 is pulled and rotated by the wire 5, and the temporary fixing portion 21 is the original path of the lowering wire 5 a as the wire guide 9 rotates. When the wire moves around to the lower left side (in FIG. 11) in the rotational direction so as to be disengaged from the wire, the wedge member 23 opposed to the temporary fixing portion 21 is deformed by the component force of the tension acting on the wire 5, and the ascending wire 5 b is released from the temporary fixing portion 21. The rotated position of the wire guide 9 is detented by the engagement between the lance 38 provided between the bracket 10 and the engagement groove 41.

[7] Example 3
For example, as shown in FIG. 12, the collar portion 13 may pass through the eccentric position of the wire guide 9 having an elliptical planar shape. When the wire guide 9 rotates from the state shown in FIG. 12A to the state shown in FIG. 12B, the wire guide 9 rotates around the collar portion 13 and the wire 5 is applied to the peripheral surface of the wire guide 9. And the wire path is extended upward, and the tension of the wire 5 is increased. In a state where the wire 5 is engaged with the temporary fixing portion 21, the wire guide 9 is pulled by the wire drum and is rotated to the right in the drawing. Then, when the position of the temporary fixing portion 21 deviates from the original position of the lifting wire 5b due to the rotation, the temporary fixing portion 21 is released by the tension of the wire 5. The rotated position of the wire guide 9 is maintained by the engagement between the lance 38 and the engagement groove 41 provided in the wire guide 9.

The embodiment has been described above with respect to the railless wire drum type window regulator 1, but the present invention can also be applied to a wire drum type window regulator using a guide rail.
Further, the rotation angle of the wire guide 9 is suitably 30 ° to 45 °, but it is within a range in which the necessary tension can be increased.
