The descending cable extends upward from the drum and has a descending cable end that engages the carrier plate (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2014-177838

Conventionally, the width of the guide rail has been shortened as compared with the conventional one from the viewpoint of promoting weight reduction. Therefore, in the wind regulator described in Patent Document 1, the two cable end accommodating portions of the carrier plate are arranged outside the width region of the guide rail so as to be arranged outside the guide rail in a plan view. There is.
The wind regulator having such a configuration has a problem that an abnormal noise is generated when the carrier plate and the window glass are raised, for example.
An object of the present invention is to suppress the generation of abnormal noise when the carrier plate is raised in the wind regulator.

Hereinafter, a plurality of aspects will be described as means for solving the problem. These aspects can be arbitrarily combined as needed.

The seemingly wind regulator of the present invention includes a guide rail, a carrier plate, an ascending cable and a descending cable.
The carrier plate has an ascending end holder for accommodating the end of the ascending cable and a descending end holder accommodating the end of the descending cable.
The ascending end holder is provided so that the ascending cable is on the outside of the guide rail.
The lower end holder is provided so that the lower cable is on the guide rail.
When the carrier plate is raised and lowered, the carrier plate is raised and lowered along the edge of the guide rail.
In this wind regulator, the descending side cable is arranged on the guide rail, so that the descending side cable easily slides on the guide rail when the carrier plate is raised and the descending side cable is pulled out. .. As a result, abnormal noise caused by vibration of the descending cable is suppressed.
In the conventional structure in which the descending cable is also arranged away from the side of the guide rail, the descending cable becomes vibrable because the load is reduced when the carrier plate is raised. When vibration was input from the outside, the descending cable was likely to vibrate. Therefore, the seemingly wind regulator of the present invention can solve the above-mentioned conventional problems.

The descending cable is in contact with the guide rail when the carrier plate is at least in the upper end restraint position with respect to the guide rail.
In this wind regulator, since the descending cable is in contact with the guide rail when the carrier plate is at least near the upper end restraint position, it is possible to effectively suppress the generation of abnormal noise caused by the vibration of the descending cable. The reason is that the descending side cable is pulled out for the longest time when it is near the upper end restraint position of the carrier plate, so that the descending side cable is likely to vibrate.

The wind regulator may further include a hooking member to which the descending cable is hung. In that case, the width of the guide rail is shorter than the outer diameter of the cable hook member.
In this wind regulator, the width of the guide rail is shorter than the outer diameter of the hooking member, so that the weight of the guide rail is reduced.

The lead-out portion of the descending cable in the cable hook member may be located on the guide rail.
In this wind regulator, the lead-out part of the descending cable is located above the guide rail, so even if the width of the guide rail is shorter than the outer diameter of the hooking member, the descending cable can be connected to the guide rail. Can be reliably placed on top.

The wind regulator according to the present invention can suppress the generation of abnormal noise when the carrier plate is raised.

The second portion 43 extends parallel to the guide rail main body 37 and extends outward in the width direction. Due to the above structure, the strength of the first side wall portion 38 is improved.

The first side wall portion 38 and the second side wall portion 39 extend along the length direction of the guide rail main body 37. However, the first side wall portion 38 and the second side wall portion 39 are provided along the guide rail main body 37, and may have at least a slidable length of the carrier plate 32, for example, the upper end and the second side wall portion 39. / Or the lower end may be a missing structure.

(3) Drive unit As shown in FIGS. 7 and 8, the drum housing 51 has a main body 51a having a fitting portion with a guide rail and a cylindrical drum accommodating portion. FIG. 7 is a perspective view showing the positional relationship between the cable lead-out groove and the guide rail. FIG. 8 is a partially enlarged front view of the wind regulator of FIG. 1, showing a drum, a drum housing, an elevating wire, and a guide rail. The main body 51a is formed with a columnar recess 53 for accommodating the drum 55. An ascending side cable outlet groove 57 and a descending side cable outlet groove 59 for leading out from the recess 53 through the ascending side cable 33 and the descending side cable 34 to the outside are formed in the main body 51a.
Further, an insertion hole 61 for fitting and fixing the lower end portion of the guide rail 31 is formed on the upper surface of the portion protruding from the upper portion to the left side of the main body 51a.

The drum 55 is rotatably held in the recess 53. Grooves for guiding the ascending side cable 33 and the descending side cable 34 are spirally formed on the outer periphery of the drum 55, and can rotate with a support shaft (not shown) formed on the bottom surface of the recess 53 of the drum housing. A recess for fitting is provided.
The drum 55 is a cable hooking member on which the descending side cable 34 is hung, and the outer diameter of the drum 55 is wider than the width of the guide rail 31. Therefore, the weight of the guide rail 31 has been reduced. The cable hooking member is not limited to the drum 55, and may be at least a member on which the descending side cable 34 can be hooked.

The drive motor 56 is a device that rotationally drives the drum, and is fixed to the drum housing 51. The drive motor 56 has a speed reducer (not shown), and the speed reducer cover 63 covers the recess 53 of the drum housing 51.

(4) Upper Cable Guide The upper cable guide 45 is, for example, a direction-changing member formed of a synthetic resin material in a semicircular shape in front view, and changes the direction of cable movement by folding back the movement of the cable, and the cable has a curved peripheral surface. A guide groove (not shown) is formed to guide the cable in a sliding state. The upper cable guide 45 can be fastened to an upper bracket (not shown) for fixing the upper end of the guide rail 31 to the door panel of the vehicle with bolts or the like, and is integrally configured with the upper bracket. It is also possible to do.
Further, the upper cable guide 45 may be any as long as it changes the moving direction of the ascending side cable 33. For example, a pulley rotatably supported by an upper bracket attached to the guide rail 31 or the upper end portion of the guide rail 31 is provided. It can also be used.

(5) Carrier plate As shown in FIG. 5, the carrier plate 32 has a main body 32a, a first guide groove 75, a second guide groove 77, an ascending end holder 79, and a descending end holder 81. ing. The main body 32a may be a substrate and may be a portion on which another structure is formed.
The first guide groove 75 and the second guide groove 77 are grooves that slide on the first side wall portion 38 and the second side wall portion 39 of the guide rail 11. As shown in FIG. 6, the first guide groove 75 and the second guide groove 77 are formed on the surface of the carrier plate 32 on the guide rail side. In this case, since the first side wall portion 38 has an L shape including the first portion 41 and the second portion 43, the gap between the first side wall portion 38 and the first guide groove 75 is small. The carrier plate 32 is less likely to rattle.
The engagement structure between the guide rail 31 and the carrier plate 32 may be such that the carrier plate 32 can be slidable by being guided by the guide rail 31. For example, a sliding groove is formed on the carrier plate 32 side to guide the guide. It is also possible to provide an engaging ridge that engages with the sliding groove on the rail 31 side.

The ascending side end holder 79 has a structure for accommodating the end 33a of the ascending side cable 33. The ascending side end holder 79 is provided so that the ascending side cable 33 is on the outer side away from the guide rail. The lowering side end holder 81 has a structure for accommodating the end 34a of the lowering side cable 34. The lowering side end holder 81 is provided so as to be on the guide rail 31 when the carrier plate 32 is attached to the guide rail 31, and when the lowering side cable 34 is wound around the drum 55 and arranged in the wind regulator 1. The lowering side cable 34 is provided on the carrier plate 32 so as to be on the guide rail 31. That is, the carrier plate 32 and the drum housing 51 are attached to the guide rail 31 so that the line connecting the lower end holder 81 and the lower cable lead-out groove 59 is on the guide rail. In this embodiment, the ascending side end holder 79 and the descending side end holder 81 are shaped to cover the side surfaces of the end 33a and the end 33b. However, the ascending end holder 79 and the descending end holder 81 are not particularly limited.
The end 33a and the end 34a are formed by, for example, die-casting a metal material, and have a base to which one end of the ascending side cable 33 or the descending side cable 34 is attached and a flange portion having an outer diameter larger than the base portion. Have. The base is formed in the shape of a cylinder or a truncated cone, and one end of the ascending cable 33 or the descending cable 34 is fixed by gluing, welding, bolting, or other methods.
A first coil spring 85 and a second coil spring 87 are attached to the end 33a and the end 34a, respectively. The first coil spring 85 and the second coil spring 87 are urging members that urge the ends 33a and 33b in the direction of removing the slack of the ascending side cable 33 and the descending side cable 34.

(6) Positional Relationship The guide rail 31 is displaced to the left side of the drawing when viewed from the front with respect to the drum 55 of the drive unit 35. More specifically, as shown in FIGS. 1 and 8, the guide rail 31 deviates from the rotation center of the drum 55 when the virtual line is extended downward.
Further, the width and length of the guide rail 31 is shorter than the outer diameter of the drum 55. Therefore, the ascending side cables 33 are arranged apart from each other on both sides of the guide rail 31.
Further, the guide rail 31 is tilted diagonally to the left in FIG. 1 and extends upward from the drive unit 35. Therefore, the carrier plate 32 moves up and down diagonally along the guide rail 31. Therefore, the carrier plate 32 is tilted to one of the guide rails 31 to reduce the gap between the two engaging portions. As a result, rattling between the carrier plate 32 and the guide rail 31 is unlikely to occur.

The lower end holder 81 of the carrier plate 32 is located on the guide rail 31.
Further, as shown in FIGS. 7 and 8, the descending side cable outlet groove 59, which is the outlet portion of the descending side cable 34 in the drum 55, is located on the guide rail 31. In this case, even if the width of the guide rail 31 is shorter than the outer diameter of the drum 55, the lowering side cable 34 can be reliably arranged on the guide rail 31.
From the above, when the carrier plate 32 is in the lower end position or the intermediate position, the lowering side cable 34 is arranged on the guide rail 31.

(7) Operation The operation of moving the window glass 20 from the lowermost position to the uppermost position will be described.
First, the window glass 20 is in the lowermost position as shown in FIGS. 1 and 2. At this time, the carrier plate 32 is located close to the upper side of the drive unit 35. Therefore, the amount of extension of the ascending cable 33 from the drum 55 is the largest, and the amount of extension of the descending cable 34 from the drum 55 is the smallest.
When the drive motor 56 rotationally drives the drum 55, the carrier plate 32 is raised, and the window glass 20 is raised accordingly.

FIG. 5 shows a state in which the carrier plate 32 rises to, for example, the intermediate portion in the longitudinal direction of the guide rail 31. As is clear from FIG. 5, the descending side cable 34 is located on the guide rail 31 in a plan view. In other words, the descending side cable 34 is contained within the width direction region of the guide rail 31.
Finally, the window glass 20 reaches the upper end restraint position as shown in FIGS. 3 and 4. At this time, the carrier plate 32 is located close to the lower side of the upper cable guide 45.

Further, when the carrier plate 32 is at least in the upper end restraint position with respect to the guide rail 31, the lowering side cable 34 is in contact with the guide rail 31. Specifically, a part or most of the descending side cable 34 is in contact with the guide rail main body 37 of the guide rail 31.
In this window regulator 1, since the lowering side cable 34 is arranged on the guide rail 31, when the carrier plate 32 rises and the lowering side cable 34 is pulled out, the lowering side cable 34 becomes the guide rail 31. It is easy to slide. As a result, the descending side cable 34 comes into contact with the guide rail 31, and the contact suppresses the vibration of the descending side cable 34, so that the abnormal noise caused by the vibration of the descending side cable 34 is suppressed.

In the present embodiment, the guide rail 31 is curved so as to be convex toward the direction in which the ascending / descending locus of the window glass 20 is located or the direction in which the descending side cable 34 is arranged. Therefore, when the window glass 20 reaches the intermediate portion in the longitudinal direction, the descending side cable 34 starts to come into contact with the surface of the guide rail 31. However, when the carrier plate 32 reaches the vicinity of the upper end position with respect to the guide rail 31 (that is, the upper limit position of the position where the carrier plate 32 can actually move due to the restraint of the window glass 20 and the position in the vicinity thereof). In addition, the descending side cable 34 may start abutting on the guide rail 31. The reason is that when the carrier plate 32 is near the upper end position, the descending side cable 34 is pulled out for the longest time and is most likely to vibrate. Therefore, suppressing the vibration of the descending side cable 34 at that time prevents abnormal noise. Because it is effective.

(8) Other Embodiments Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the invention. .. In particular, the plurality of embodiments and modifications described herein can be arbitrarily combined as needed.
The main part of the design in the drawings of the above embodiment is the positional relationship between the guide rail and the elevating side cable and the descending side cable, and more specifically, when the carrier plate is at the lower end position or the intermediate position of the guide rail. In the front view and the rear view, the ascending side cables are arranged on both sides of the guide rail, and in the rear view, the descending side cables are arranged on the guide rails. That is, in the wind regulator, as shown in FIGS. 9 to 14, the part represented by the solid line is the part having the characteristic appearance of the wind regulator, and the right of the characteristic part is to be obtained. It is also something to do.

The present invention can be applied to a wind regulator for raising and lowering a window glass of an automobile.
