Description

Technical Field

[0001] The present invention relates to a window regulator.

Background Art

[0002] Conventionally, as a window regulator, there is one in which a wire lead-out groove for leading out a wire is curved in an "S" shape (see Patent Document 1). This window regulator includes a guide rail arranged along the moving direction of a window glass, a carrier plate to which the window glass is connected, a drum that is rotationally driven by the operation of a motor, a wire having one end connected to the carrier plate and the other end connected to the drum, a wire end fixed to one end of the wire, and a coil spring that applies tension to the wire. The carrier plate is formed with a wire end accommodating portion for accommodating the wire end and the coil spring, and a wire lead-out groove for leading out the wire from the bottom of the wire end accommodating portion toward the outside of the carrier plate. In this window regulator, by curving the wire lead-out groove in an "S" shape, it is possible to suppress the transmission of vibration of the wire arranged outside the carrier plate to the wire arranged inside the wire end accommodating portion.

[0009] The following describes a window regulator according to one embodiment of the present invention, with reference to the attached drawings. This window regulator is a lifting device installed inside a vehicle door in a vehicle (for example, an automobile) that raises and lowers the window glass of the vehicle door. In particular, this window regulator is equipped with a wire outlet groove that leads the lowering wire to the outside of the carrier plate, and a detachment prevention structure that prevents the lowering wire from detaching from the wire outlet groove. Hereafter, the direction in which the vehicle's window glass is raised and lowered will be simply referred to as the "raising and lowering direction." Furthermore, as shown in each figure, left and right, front and back, and up and down will be defined and described below. In this embodiment, the raising and lowering direction and the up and down direction of the window regulator are assumed to coincide, and the vehicle width direction and the front and back direction of the window regulator are assumed to coincide. Furthermore, the direction perpendicular to the raising and lowering direction and the vehicle width direction will be referred to as the left and right direction of the window regulator.

[0010] (Window regulator configuration) As shown in Figures 1 and 2, the window regulator 1 is attached to a vehicle door D and includes a carrier plate 11 that supports the window glass G, a guide rail 12 that slidably supports the carrier plate 11 in the vertical direction, an upward wire 13 and a downward wire 14 that pull the carrier plate 11, a drive unit 15 disposed in the vertical center of the guide rail 12 that drives the upward wire 13 and the downward wire 14, a pulley 16 provided at the upper end of the guide rail 12 via a pulley bracket 17 that changes the direction of the upward wire 13, and a wire guide 18 provided at the lower end of the guide rail 12 that changes the direction of the downward wire 14. In other words, this window regulator 1 is a wire-driven window regulator that raises and lowers the carrier plate 11 using wires 13 and 14, and is a banjo-type window regulator in which the drive unit 15 is disposed in the vertical center of the guide rail 12. Note that the upward wire 13 and the downward wire 14 are examples of wires. Furthermore, the upward wire 13, the downward wire 14, and the drive unit 15 are examples of lifting and lowering means for raising and lowering the carrier plate 11 along the guide rail 12.

[0011] Furthermore, as shown in Figure 3, the window regulator 1 includes an upward-side slide bush 21 fixed to the carrier plate 11 side end of the upward-side wire 13, an upward-side spring 22 that applies tension to the upward-side wire 13 via the upward-side slide bush 21, a downward-side slide bush 23 fixed to the carrier plate 11 side end of the downward-side wire 14, and a downward-side spring 24 that applies tension to the downward-side wire 14 via the downward-side slide bush 23. The upward-side slide bush 21 and the downward-side slide bush 23 are examples of wire fixing members.

[0012] As shown in Figure 1, the guide rail 12 is formed by curving a long, plate-shaped metal plate outward from the vehicle interior with a predetermined curvature, and is positioned at an angle to the rear in the vehicle's longitudinal direction relative to the vehicle door D. Furthermore, as shown in Figure 2, the guide rail 12 integrally comprises a plate-shaped base portion 31 that has width in the left-right direction and extends in the up-down direction, a right plate portion and a left plate portion (not shown) erected on the front side from both ends in the width direction of the base portion 31, a right flange portion 32 formed by projecting to the right from the front end of the right plate portion, and a left flange portion 33 formed by projecting to the left from the front end of the left plate portion.

[0013] The upward wire 13 has one end connected to the rotating drum (not shown) of the drive unit 15, is fed out from the drive unit 15 to the upper right, reaches the pulley 16, is redirected downward by the pulley 16, and the other end is attached to the upward slide bush 21 in the carrier plate 11. On the other hand, the downward wire 14 has one end connected to the rotating drum of the drive unit 15, is fed out from the drive unit 15 to the lower right, reaches the wire guide 18, is redirected upward by the wire guide 18, and the other end is attached to the downward slide bush 23 in the carrier plate 11.

[0014] The drive unit 15 is attached to the middle part in the vertical direction of the guide rail 12, has a drive motor, a speed reducer, and a rotating drum, and drives the ascending wire 13 and the descending wire 14. Specifically, when the drive motor of the drive unit 15 is driven forward, the rotating drum rotates forward. Along with this, the descending wire 14 is fed out from the rotating drum while the ascending wire 13 is wound around the rotating drum. As a result, the carrier plate 11 is pulled by the ascending wire 13 and moves upward in the vertical direction. Thereby, the window glass G attached to the carrier plate 11 rises. On the other hand, when the drive motor of the drive unit 15 is driven reversely, the rotating drum rotates reversely. Along with this, the ascending wire 13 is fed out from the rotating drum while the descending wire 14 is wound around the rotating drum. As a result, the carrier plate 11 is pulled by the descending wire 14 and moves downward in the vertical direction. Thereby, the window glass G attached to the carrier plate 11 descends. By these means, the carrier plate 11 and the window glass G are moved up and down along the guide rail 12 (the up and down movement operation of the window glass G).

[0015] (Configuration of the carrier plate) Next, referring to FIGS. 3 to 8, the carrier plate 11 will be described. As shown in FIGS. 3 and 4, the carrier plate 11 is formed of a resin and a metal plate integrated by insert molding, and includes a plate-like main body portion 41, two mounting holes 42, 42 formed at the left and right end portions of the main body portion 41, a rail mounting portion 43 formed at the right side of the center of the main body portion 41, a descending-side accommodating portion 44 formed at the left side of the rail mounting portion 43 for accommodating the descending-side slide bush 23 and the descending-side spring 24, a descending-side wire leading-out portion 45 formed below the descending-side accommodating portion 44 for leading out the descending wire 14 from the descending-side accommodating portion 44, an ascending-side accommodating portion 46 formed at the left side of the descending-side wire leading-out portion 45 for accommodating the ascending-side slide bush 21 and the ascending-side spring 22, and an ascending-side wire leading-out portion 47 formed above the ascending-side accommodating portion 46 for leading out the ascending wire 13 from the ascending-side accommodating portion 46. The descending-side accommodating portion 44 and the ascending-side accommodating portion 46 are examples of accommodating portions.

[0016] The mounting holes 42, 42 are for bolt-fastening a schematic glass holder fixed to the window glass G. By fastening the glass holder to the mounting holes 42, 42 with bolts, the window glass G is attached to the carrier plate 11 via the glass holder.

[0017] The rail mounting portion 43 is formed at the upper and lower ends on the back side of the main body portion 41, and includes a pair of upper and lower side plate sliding portions 51, 52 that slide on the right side plate portion of the guide rail 12, a rectangular opening portion 53 opened in the main body portion 41 between the pair of side plate sliding portions 51, 52, and a plurality of sliding fins 54, 54, 54 disposed on the rectangular opening portion 53 and sliding on the right flange portion 32 of the guide rail 12. The carrier plate 11 is supported by this rail mounting portion 43 so as to be movable up and down with respect to the guide rail 12.

[0018] As shown in FIG. 3, the ascending-side accommodating portion 46 has a hollow portion in the shape of an octagonal prism and is formed in a bottomed hole shape with the upper side as the bottom side, and has an inner surface and a bottom surface. The ascending-side accommodating portion 46 accommodates the ascending-side slide bush 21 in the hollow portion so as to be able to advance and retreat in the vertical direction. Further, the ascending-side accommodating portion 46 accommodates the ascending-side spring 22 in a compressed state between the flange portion of the ascending-side slide bush 21 and the bottom surface. Inside the ascending-side accommodating portion 46, the ascending-side spring 22 presses the ascending-side slide bush 21 downward with the bottom surface as a support, and thereby, tension is applied to the ascending-side wire 13 via the ascending-side slide bush 21.

[0019] As shown in FIG. 4, the ascending-side wire lead-out portion 47 is formed in a groove shape with the rear side as the opening side, and is formed to extend upward from the bottom surface of the ascending-side accommodating portion 46. The ascending-side wire 13 connected to the ascending-side slide bush 21 is pulled upward from the ascending-side accommodating portion 46 by the ascending-side wire lead-out portion 47 and led out to the outside of the carrier plate

[0020] As shown in Figure 3, the lower side housing 44 has an octagonal prism-shaped hollow section and is formed as a bottomed hole with the lower side being the bottom, and has an inner surface and a bottom surface. Within the hollow section of the lower side housing 44, the lower side slide bush 23 is housed so that it can move back and forth in the vertical direction. The lower side housing 44 also houses the lower side spring 24 in a compressed state between the flange portion and the bottom surface of the lower side slide bush 23. Inside the lower side housing 44, the lower side spring 24 presses the lower side slide bush 23 upward using the bottom surface as a support, thereby applying tension to the lower side wire 14 via the lower side slide bush 23.

[0021] (Configuration of the descending wire outlet) As shown in Figures 4 and 5, the descending wire outlet section 45 includes a wire outlet groove 61 that forms a wire outlet path R, a first claw portion 62 that protrudes from the left inner edge of the wire outlet groove 61 at an intermediate position in the wire outlet path R, a second claw portion 63 that protrudes from the right inner edge of the wire outlet groove 61 at the end position of the wire outlet path R, and a regulating projection 64 that protrudes from the left side wall of the wire outlet groove 61 just before the end position of the wire outlet path R. The first claw portion 62 and the second claw portion 63 are examples of protruding portions.

[0022] As shown in Figure 5, the wire outlet groove 61 forms a wire outlet path R that curves in a mountain-like shape with its peak on the right side, serving as a path for leading the descending wire 14 from the descending housing section 44 to outside the carrier plate 11 (below the carrier plate 11). In detail, the wire outlet path R extends downward from the descending housing section 44, then curves downward to the right, then curves downward to the left as if folding back to the left, and then curves downward. Hereinafter, the portion curved downward to the right will be referred to as the first curved section R1, the portion curved downward to the left as if folding back to the left will be referred to as the second curved section R2, and the portion curved downward will be referred to as the third curved section R3. Note that the first curved section R1, the second curved section R2, and the third curved section R3 are examples of curved sections.

[0023] Furthermore, as shown in Figures 5 to 7, the wire outlet groove 61 is formed in a groove shape with the rear side being the open side, and is provided along the wire outlet path R from the bottom surface of the lower side housing section 44. In addition, the wire outlet groove 61 has a wider groove width at the positions of the first curved section R1 and the third curved section R3. Furthermore, at the position of the second curved section R2, the wire outlet groove 61 is positioned facing the rectangular opening 53, and the groove bottom and right side wall are omitted. Moreover, at the end position of the wire outlet path R, the left side wall of the wire outlet groove 61 is omitted.

[0024] Furthermore, in the wire outlet groove 61, inclined surfaces 61a, 61a, 61a are formed on the right inner edge (upper end of the right side wall) of the position of the first curved section R1, the left inner edge (upper end of the left side wall) of the position of the lower half of the second curved section R2, and the right inner edge (upper end of the right side wall) of the position of the third curved section R3, sloping downward toward the front side (towards the bottom of the wire outlet groove 61) toward the inside in the groove width direction of the wire outlet groove 61. These features make it easier to introduce the descending wire 14 into the wire outlet groove 61 at the positions of the first curved section R1, the second curved section R2, and the third curved section R3.

[0025] As shown in Figures 5, 6, and 8, the first claw portion 62 is positioned to straddle the wire outlet path R at the location of the second curved portion R2, and is formed to protrude inward in the groove width direction from the left inner edge (upper end of the left side wall) of the wire outlet groove 61 on the opening side of the wire outlet groove 61. Furthermore, the front surface 62a of the first claw portion 62 is a locking surface that locks the descending wire 14 from the rear, and this front surface 62a contacts the rear side of the descending wire 14 introduced into the wire outlet groove 61, locking the descending wire 14 in the front-rear direction. This prevents the descending wire 14 from detaching from the wire outlet groove 61 to the rear (towards the front side in the groove depth direction of the wire outlet groove 61) at the location of the second curved portion R2.

[0026] Furthermore, a guide slope 62b is formed at the upper end of the rear surface of the first claw portion 62 (the surface on the near side in the groove depth direction of the wire outlet groove 61), which slopes downward toward the front side (groove width direction) of the first claw portion 62 (groove bottom side of the wire outlet groove 61). When the descending wire 14 is introduced into the wire outlet groove 61, the descending wire 14 comes into contact with the guide slope 62b, which guides the descending wire 14 to the front side of the first claw portion 62, bypassing the first claw portion 62 and being introduced into the wire outlet groove 61.

[0027] Furthermore, a slope 62c is formed on the upper end of the front surface of the first claw portion 62, which slopes upward toward the base end of the first claw portion 62. This slope 62c makes it easier for the descending wire 14, which has been guided toward the front of the first claw portion 62 by the guiding slope 62b, to move onto the wire exit path R located toward the base of the first claw portion 62.

[0028] As shown in Figures 5, 7, and 8, the second claw portion 63 is positioned to straddle the wire outlet path R at the end of the wire outlet path R, and is formed to protrude inward (to the left) in the groove width direction from the right inner edge (upper end of the right side wall) of the wire outlet groove 61 on the opening side of the wire outlet groove 61. Furthermore, the front surface 63a of the second claw portion 63 is a locking surface that locks the descending wire 14 from the rear, and this front surface 63a contacts the rear side of the descending wire 14 introduced into the wire outlet groove 61, locking the descending wire 14 in the front-rear direction. This prevents the descending wire 14 from detaching from the wire outlet groove 61 to the rear (towards the front in the groove depth direction of the wire outlet groove 61) at the end of the wire outlet groove 61.

[0029] Furthermore, a guide slope 63b is formed on the entire rear surface of the second claw portion 63 (the surface on the front side in the groove depth direction of the wire outlet groove 61), sloping downwards toward the front side (groove bottom side of the wire outlet groove 61) toward the tip side (groove width direction) of the second claw portion 63. When the descending wire 14 is introduced into the wire outlet groove 61, the descending wire 14 comes into contact with the guide slope 63b, guiding the descending wire 14 to the front side of the second claw portion 63, bypassing the second claw portion 63, and being introduced into the wire outlet groove 61.

[0030] As shown in Figures 5 and 7, the restricting projection 64 is formed to protrude to the right from the left side wall of the wire outlet groove 61 at a position just before the end of the wire outlet groove 61, and contacts the left side of the descending wire 14 to restrict the movement of the descending wire 14 to the left. By restricting the movement of the descending wire 14 introduced into the wire outlet groove 61 toward the tip of the second claw portion 63, this restricting projection 64 prevents the descending wire 14 introduced into the wire outlet groove 61 from bypassing the tip of the second claw portion 63 and coming out of the wire outlet groove 61. In particular, in the state before tension is applied to the descending wire 14 during the assembly of the window regulator 1, this prevents the descending wire 14 from bypassing the tip of the second claw portion 63 and coming out of the wire outlet groove 61.

[0031] (Explanation of the lowering wire attachment procedure) The operation for attaching the descending wire 14 to the carrier plate 11 will now be described with reference to Figures 9 to 11. This operation involves housing the descending slide bush 23 and the descending spring 24 in the descending housing section 44 and introducing the descending wire 14 into the wire outlet groove 61.

[0032] In the lowering wire installation operation, first, as shown in Figure 9(b), the lowering slide bush 23 and the lowering spring 24 are housed in the lowering housing 44. Once the lowering slide bush 23 and the lowering spring 24 are housed in the lowering housing 44, as shown in Figure 10(a), the lowering wire 14 is routed along the right side wall of the wire outlet groove 61 at the first curved section R1. Then, as shown in Figure 10(b), the lowering wire 14 is introduced into the wire outlet groove 61 by holding its leading end and pulling it downwards to the right while pressing it against the wire outlet groove 61. At this time, the lowering wire 14 comes into contact with the guide slope 62b of the first claw portion 62, guiding the lowering wire 14 to the leading end of the first claw portion 62, bypassing the first claw portion 62, and being introduced into the wire outlet groove 61. As a result, the descending wire 14 is introduced below the first claw portion 62, and at the position of the second curved portion R2, the detachment of the descending wire 14 from the wire outlet groove 61 is suppressed.

[0033] Subsequently, as shown in Figure 11(a), at the second curved section R2, the descending wire 14 is routed along the left wall of the wire outlet groove 61, and at the third curved section R3, the descending wire 14 is routed along the right wall of the wire outlet groove 61. Then, as shown in Figure 11(b), the descending wire 14 is introduced into the wire outlet groove 61 by holding its leading end and pulling it downwards while pushing it against the wire outlet groove 61. At this time, the descending wire 14 comes into contact with the guide slope 63b of the second claw section 63, guiding it to the leading end of the second claw section 63, and it is introduced into the wire outlet groove 61 by bypassing the second claw section 63. As a result, the descending wire 14 is introduced below the second claw section 63, and at the end of the wire outlet path R, the detachment of the descending wire 14 from the wire outlet groove 61 is suppressed. This completes the installation of the main descent wire.

[0034] (Effects and workings of the embodiment) As described above, according to the configuration of the embodiment, by providing claw portions 62 and 63 that protrude from the inner edge of the wire outlet groove 61, the downward wire 14 introduced into the wire outlet groove 61 is locked in the front-rear direction (groove depth direction) by the claw portions 62 and 63, thereby preventing the downward wire 14 introduced into the wire outlet groove 61 from coming out of the wire outlet groove 61. In particular, when assembling the window regulator 1, before tension is applied to the downward wire 14, it is possible to prevent the downward wire 14 introduced into the wire outlet groove 61 from coming out of the wire outlet groove 61, thus making the assembly work of the window regulator 1 easier. Furthermore, by arranging the second claw portion 63 at the end position of the wire outlet path R (end position of the wire outlet groove 61), it is possible to prevent the downward wire 14 introduced into the wire outlet groove 61 from coming out of the wire outlet groove 61 during the raising and lowering operation of the window glass G. Therefore, it is possible to suppress the occurrence of defects in the lifting and lowering operation due to the detachment of the lowering wire 14 from the wire outlet groove 61.

[0035] Furthermore, by employing a wire outlet groove 61 that forms a curved wire outlet path R, sliding resistance is generated between the wire outlet groove 61 and the descending wire 14 at the positions of the curved sections R1, R2, and R3, thereby appropriately increasing the sliding resistance between the wire outlet groove 61 and the descending wire 14. This makes it possible to suppress judder (abnormal vibration) of the window glass G during its raising and lowering operation. In order to suppress the judder of the window glass G, it is preferable to set the sliding resistance value between the wire outlet groove 61 and the descending wire 14 to 3.1N or higher. That is, in this embodiment, the wire outlet groove 61 is formed so that the sliding resistance value with the descending wire 14 during the raising and lowering operation of the window glass G is 3.1N or higher.

[0036] Furthermore, in a configuration employing a wire outlet groove 61 that forms a curved wire outlet path R, by arranging a second claw portion 63 at the terminal position of the wire outlet path R, it is possible to suppress the downward wire 14 introduced into the wire outlet groove 61 from coming out of the wire outlet groove 61 during the raising and lowering operation of the window glass G. This makes it possible to avoid as much as possible the situation in which the wire 14 comes out of the wire outlet groove 61 during the raising and lowering operation of the window glass G, and the judder suppression effect due to sliding between the wire outlet groove 61 and the downward wire 14 cannot be obtained, thereby suppressing the occurrence of judder during the raising and lowering operation of the window glass G.

[0037] Furthermore, the formation of inclined surfaces 61a on the inner edges of the curved sections R1, R2, and R3 in the wire outlet groove 61 makes it easier to introduce the descending wire 14 into the wire outlet groove 61 at the curved sections R1, R2, and R3.

[0038] Furthermore, by providing guide slopes 62b and 63b on the rear surfaces of the claw portions 62 and 63, the descending wire 14 can be easily introduced below the claw portions 62 and 63.

[0039] (Regarding other embodiments) Although embodiments of the present invention have been described above, these embodiments do not limit the invention as defined in the claims. Furthermore, it should be noted that not all combinations of features described in the embodiments are necessarily essential for solving the problem of the invention. The present invention can be implemented with appropriate modifications without departing from its spirit.

[0040] For example, in the above embodiment, the configuration had a first claw portion 62 and a second claw portion 63, but it may also have a configuration with only one of the first claw portion 62 and the second claw portion 63. Alternatively, the claw portions 62 and 63 may be arranged at the positions of the first curved portion R1 and the third curved portion R3.

[0041] Furthermore, in the above embodiment, the wire outlet groove 61 was configured to form a curved wire outlet path R, but the wire outlet groove 61 may also be configured to form a straight wire outlet path R. That is, the present invention may be applied to a descending wire outlet section 45 that employs a wire outlet groove 61 that forms a straight wire outlet path R.

[0042] Furthermore, although the present invention was applied to the descending wire outlet section 45 in the above embodiment, the present invention may also be applied to the ascending wire outlet section 47. That is, the ascending wire outlet section 47 may have a configuration that includes claw sections 62 and 63.

[0043] Furthermore, in the above embodiment, the present invention was applied to a banjo-type window regulator 1 in which the drive unit 15 is disposed in the vertical center of the guide rail 12, but it is not limited to this as long as it is a wire-driven window regulator. For example, the present invention may be applied to a lower-end rail type window regulator in which the drive unit 15 is disposed at the lower end of the guide rail 12, or to a window regulator (such as a delta-type window regulator) in which the drive unit 15 is directly fixed to the vehicle door D (door panel).
