[0002] This application claims the priority of Japanese Patent Application No. 2020 - 060551, filed with the Japan Patent Office on March 30, 2020, the entire content of which is incorporated herein by reference. Technical field

[0003] One aspect of the present application relates to a wire regulator. Background art

[0004] Generally, a regulator for opening and closing a vehicle window glass is provided in the space between the inner panel and the outer panel of a door.

[0005] As the regulator, a wire regulator can be used. Such a wire regulator includes: a guide rail provided along the ascending and descending direction of the window glass, a slider that mounts the window glass and is movably engaged with the guide rail, a rising cable, a falling cable, and a drive unit. One end of the rising cable is fixed to the wire end receiving portion of the slider. The rising cable applies a force in the direction of pulling the cable and extends upward of the slider. One end of the falling cable is fixed to the wire end receiving portion of the slider. The falling cable applies a force in the direction of pulling the cable and extends downward of the slider. The drive unit drives the drum around which the rising cable is wound and the drum around which the falling cable is wound. The drive unit pays out or winds the falling cable and the rising cable wound around the drum, so that the slider ascends or descends along the guide rail.

[0006] In such a wire regulator, rainwater or the like that is transmitted to the window glass and intrudes into the door interior flows downward via the guide rail, the slider, and the falling cable, etc., so there is a case where the guide rail or the falling cable rusts.

[0007] To suppress this situation, a technique of providing an eaves portion (rainwater conduit) on the slider has been disclosed (see Patent Document 1). Such an eaves portion guides rainwater or the like that intrudes into the door interior to a position where it will not be transmitted to the guide rail and the falling cable.

[0020] In the following detailed description, for the purpose of explanation, many specific details are set forth in order to provide a complete understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, well-known structures and devices are schematically shown to simplify the drawings.

[0021] When an eaves portion is provided on the slider, there is a possibility that the eaves portion and the raising cable interfere with each other.

[0022] In order to avoid such interference, it is conceivable to divide the eaves into two equal parts and pass the ascending cable between the two equal parts of the eaves. However, in such a structure, there is a possibility that rainwater or the like intrudes into the wire end storage part from between the two equal parts of the eaves. In this case, rainwater or the like may freeze in the wire end storage part at low temperatures, causing the wire regulator to malfunction.

[0023] An object of the present application is to provide a linear regulator capable of suppressing rust on cables and guide rails and suppressing malfunction of the linear regulator.

[0024] A line regulator according to one aspect of the present application (the present line regulator) comprises:

[0025] A guide rail, wherein the guide rail is arranged along the lifting direction of the vehicle window glass;

[0026] A sliding member, on which the vehicle window glass is mounted and which is movably engaged with the guide rail;

[0027] a lifting cable, one end of which is locked in the lifting wire end storage portion, and the lifting cable extends toward the upper side of the sliding member; and

[0028] a descending cable, one end of which is locked in the descending wire end storage portion, and the descending cable extends toward the bottom of the sliding member,

[0029] The ascending cable and the descending cable move along the guide rail, so that the slide member ascends or descends along the guide rail.

[0030] The extending direction of the ascending cable is a direction intersecting with the falling direction of rainwater, etc.

[0031] The line regulator also includes:

[0032] a first rainwater guide having an eaves portion and formed on a side of the slider across the ascending cable; and

[0033] A second rainwater guiding portion, which has an eaves portion and is formed on the other side of the sliding member across the ascending cable.

[0034] The eaves portion of the first rainwater guiding portion and the eaves portion of the second rainwater guiding portion are configured to be offset from each other in the falling direction of rainwater or the like.

[0035] Other technical features of the present application will become clearer through the embodiments and drawings for implementing the present application described below.

[0036] In this wire type regulator, the extending direction of the ascending cable is a direction intersecting the falling direction of rainwater or the like. Further, this wire type regulator further includes: a first rainwater guiding portion, which has an eaves portion and is formed on one side of the sliding member across the ascending cable; and a second rainwater guiding portion, which has an eaves portion and is formed on the other side of the sliding member across the ascending cable. And, the eaves portion of the first rainwater guiding portion and the eaves portion of the second rainwater guiding portion are configured to be offset from each other in the falling direction of rainwater or the like.

[0037] Thereby, it is possible to suppress rainwater or the like from intruding into the wire end storage portion. Thus, it is possible to suppress the situation where rainwater or the like freezes inside the wire end storage portion at low temperatures, resulting in poor operation of the wire type regulator.

[0038] Other technical effects of the present application will become clearer through the embodiments and drawings for implementing the present application described below.

[0039] First, refer to Figures 6 to 8 to describe the wire type regulator of this embodiment. Figure 6 This is the front view of the main part of the wire type regulator of this embodiment. Figure 7 This is Figure 6 the left view of the wire type regulator shown. Figure 8 This is Figure 6 the right view of the wire type regulator shown.

[0040] In these figures, the guide rail 1 is provided on the inner panel of the door along the lifting direction of the window glass. The sliding member 3 for holding the window glass is movably engaged with this guide rail 1.

[0041] One end portion of the ascending cable 31 extending upward toward the sliding member 3 and one end portion of the descending cable 35 extending downward toward the sliding member 3 are respectively fixed to the sliding member 3.

[0042] The other end of the ascending cable 31 is wound around a drum not shown in the figure. In addition, the other end of the descending cable 35 is wound around another drum not shown in the figure. And, by driving these drums to rotate, the descending cable 35 wound around the drums and the ascending cable 31 wound around the drums are released from the drums or wound around the drums. As a result, the slider 3 rises or falls along the guide rail 1. That is, the ascending cable 31 and the descending cable 35 move along the guide rail 1, so that the slider 3 rises or falls along the guide rail 1.

[0043] Next, refer to Figures 1 to 5 The slider 3 will be described. Figure 1 for Figure 6 An enlarged view of the slide is shown. Figure 2 for Figure 1 Left side view of the slide shown. Figure 3 for Figure 1 Right side view of the slide shown. Figure 4 As viewed from the right Figure 1 A perspective view of the sliding member is shown. Figure 5 As viewed from the left Figure 1 A perspective view of the sliding member is shown.

[0044] The sliding member 3 of this embodiment is an insert molded product of a resin member and a metal member. The sliding member 3 is roughly divided into a plate-shaped metal portion 11 and a resin portion 51. The resin portion 51 covers the surface FS of the metal portion 11 (see Figure 2 , Figure 3 ) and back BS (refer to Figure 2 , Figure 3 ) part.

[0045] The resin portion 51 on the surface FS side of the metal portion 11 is divided into a first resin portion 53 located at an upper portion and a second resin portion 55 located at a lower portion via slits S and S′.

[0046] The window glass 5 is placed via a bracket on the upper portion of the metal portion 11. The metal portion 11 is formed with two holes 13 and 15 to which the bracket is attached.

[0047] The first resin portion 53 of the resin portion 51 is formed with a lifting wire end storage portion (cable assembly portion) 57. The lifting wire end storage portion 57 is provided with (locked with) a wire end 33 of the lifting cable 31 extending toward the upper side of the slider 3. And, by a force-applying device (not shown) that applies force to the wire end 33, the lifting cable 31 is forced in the direction of pulling the lifting cable 31. Furthermore, the slider 3 is formed with a groove 61 (lifting cable groove) that guides the lifting cable 31 to the lifting wire end storage portion 57.

[0048] In addition, Figure 1In [the figure], the falling direction of rainwater, etc. is indicated by an arrow. Moreover, the extending direction of the groove 61 for guiding the upward cable 31 to the upper part of the slider 3 is: a direction intersecting the falling direction of rainwater, etc. indicated by the arrow R.

[0049] Furthermore, a downward wire end storage part (cable assembly part) 63 is formed in the first resin part 53 of the resin part 51. The downward wire end 37 of the downward cable 35 extending toward the lower part of the slider 3 is set (fixed) in the downward wire end storage part 63. And, by a biasing device (not shown) that biases the wire end 37, the downward cable 35 is biased in the direction of pulling the downward cable 35. Furthermore, the slider 3 is formed with a groove 67 (downward cable groove) for guiding the downward cable 35 to the downward wire end storage part 63. And, the extending direction of the groove 67 for guiding the downward cable 35 to the lower part of the slider 3 is: a direction intersecting the falling direction of rainwater, etc. indicated by the arrow R.

[0050] On one side of the groove 61 for guiding the upward cable 31, a rainwater guiding part (first rainwater guiding part) 70 having a plurality of eaves is provided. In addition, on the other side of the groove 61, a rainwater guide rail guiding part (second rainwater guiding part) 80 having a plurality of eaves is provided. That is, the rainwater guiding part 70 is formed on one side of the slider 3 with the upward cable 31 interposed therebetween. In addition, the rainwater guide rail guiding part 80 is formed on the other side of the slider 3 with the upward cable 31 interposed therebetween.

[0051] Hereinafter, the rainwater guiding part 70 will be described. A first eaves part 71 is formed on one side of the groove 61 for guiding the upward cable 31. The first eaves part 71 receives rainwater, etc. falling from the window glass 5. The first eaves part 71 is inclined downward along a direction away from the upward cable 31. The upper end part of the first eaves part 71 is adjacent to the groove 61.

[0052] A second eaves part 73 is formed below the first eaves part 71. The second eaves part 73 includes: a repeating part 73a, a downward extending part 73b, and an inclined part 73c. The repeating part 73a coincides with the first eaves part 71 in the falling direction of rainwater, etc. That is, the rainwater guiding part 70 has two eaves parts (the first eaves part 71 and the second eaves part 73) that coincide with each other in the falling direction of rainwater, etc. The downward extending part 73b is connected and provided at the lower end part of the repeating part 73a and extends downward. The inclined part 73c is connected and provided at the lower end part of the downward extending part 73b. The inclined part 73c is inclined downward along a direction away from the upward wire end storage part (cable assembly part) 57. In addition, the first eaves part 71 and the second eaves part 73 are formed in the first resin part 53.

[0053] In addition, in the present embodiment, the upper ends of the first eaves portion 71 and the second eaves portion 73 are formed above the lower end of the wire end storage portion 57 for ascending.

[0054] The second resin portion 55 is formed with a third eaves portion 75. The third eaves portion 75 includes an inclined portion 75a and an upright wall portion (terminal portion) 75b. The inclined portion 75a is inclined downward along a direction away from the wire end storage portion (cable assembly portion) 57 for ascending. The inclined portion 75a guides rainwater or the like to the edge portion of the slider 3 (the outer side of the side portion of the guide rail 1 (refer to Figure 6 ). The upright wall portion 75b is connected and provided at the lower end of the inclined portion 75a. The upright wall portion 75b projects upward from the upper surface of the inclined portion 75a and extends to the back surface B.S. The upright wall portion 75b guides rainwater or the like so that the rainwater does not contact the back surface of the guide rail 1.

[0055] Further, the lower end portion 73d of the inclined portion 73c of the second eaves portion 73 and the upper end portion 75c of the inclined portion 75a of the third eaves portion 75 overlap each other in the falling direction of rainwater or the like indicated by the arrow R.

[0056] Next, the rainwater guide portion 80 for the guide rail will be described. An eleventh eaves portion 81 is formed on the other side of the groove 61 for guiding the ascending cable 31. The eleventh eaves portion 81 receives rainwater or the like falling from the window glass 5. The eleventh eaves portion 81 is inclined downward along a direction away from the ascending cable 31. The upper end portion of the eleventh eaves portion 81 is adjacent to the groove 61.

[0057] The eleventh eaves portion 81 includes a first inclined portion 81a on the upper side and a second inclined portion 81b. The second inclined portion 81b is connected and provided at the lower end portion of the first inclined portion 81a and has a gentler inclination angle than the inclination angle of the first inclined portion 81a. Further, the eleventh eaves portion 81 is formed above the first eaves portion 71 in the falling direction R of rainwater or the like. The first eaves portion 71 and the eleventh eaves portion 81 are formed to be offset from each other in the falling direction of rainwater or the like.

[0058] Below the eleventh eaves portion 81, a twelfth eaves portion 83 is formed. The twelfth eaves portion 83 includes a repeating portion 83a, a downward extending portion 83b, and an inclined portion 83c. The repeating portion 83a coincides with the eleventh eaves portion 81 in the falling direction of rainwater or the like. That is, the rainwater guide portion 80 has two eaves portions (the eleventh eaves portion 81 and the twelfth eaves portion 83) that coincide with each other in the falling direction of rainwater or the like. The downward extending portion 83b is connected and provided at the lower end portion of the repeating portion 83a and extends downward. The inclined portion 83c is connected and provided at the lower end portion of the downward extending portion 83b. The inclined portion 83c is inclined downward along the direction away from the downward wire end storage portion (cable assembly portion) 63. Further, the twelfth eaves portion 83 is formed above the second eaves portion 73 in the falling direction R of rainwater or the like. The second eaves portion 73 and the twelfth eaves portion 83 are formed so as to be offset from each other in the falling direction of rainwater or the like.

[0059] Below the twelfth eaves portion 83, a thirteenth eaves portion 85 is formed, and the thirteenth eaves portion 85 receives rainwater or the like falling from the lower end of the twelfth eaves portion 83. The thirteenth eaves portion 85 is inclined downward along the direction away from the downward wire end storage portion (cable assembly portion) 63. The thirteenth eaves portion 85 has an inclined portion 85a and an upright wall portion (terminal portion) 85b. The inclined portion 85a guides rainwater or the like to the edge portion of the slider 3 (the outer side of the side portion of the guide rail 1 (refer to Figure 6 )). The upright wall portion 85b is connected and provided at the lower end of the inclined portion 85a. The upright wall portion 85b protrudes upward from the upper surface of the inclined portion 85a and extends to the back surface B.S. The upright wall portion 85b guides rainwater or the like so that the rainwater does not contact the back surface of the guide rail 1. In addition, the eleventh eaves portion 81 and the twelfth eaves portion 83 are formed in the first resin portion 53. In addition, the thirteenth eaves portion 85 is formed in the second resin portion 55. Further, the thirteenth eaves portion 85 is formed above the third eaves portion 75 in the falling direction R of rainwater or the like.

[0060] In addition, in the present embodiment, the upper ends of the eleventh eaves portion 81 and the twelfth eaves portion 83 are formed above the lower end of the upward wire end storage portion 57.

[0061] Moreover, the first eaves portion 71 of the rainwater guide portion 70 and the eleventh eaves portion 81 of the rainwater guide rail portion 80 are formed in the following manner. That is, when observing the groove 61 through which the upward cable 31 passes from above the slider 3, at least either the upper end portion of the first eaves portion 71 of the rainwater guide portion 70 or the upper end portion of the eleventh eaves portion 81 of the rainwater guide rail portion 80 overlaps with the opening 61a of the groove 61 through which the upward cable 31 passes, and thus the opening 61a of the groove 61 through which the upward cable 31 passes cannot be seen.

[0062] Next, the flow of rainwater and the like that falls on the rainwater guiding portion 70 and the rainwater guide rail guiding portion 80 will be described.

[0063] The rainwater and the like that fall on the side of the rainwater guiding portion 70 will fall on the upper surfaces of the first eaves portion 71, the second eaves portion 73, and the third eaves portion 75. Then, the rainwater and the like that fall on each eaves portion move downward. The rainwater and the like are finally guided by the upright wall portion (terminal portion) 75b of the third eaves portion 75, so that they do not contact the back surface of the guide rail 1.

[0064] The rainwater and the like that fall on the side of the rainwater guide rail guiding portion 80 will fall on the upper surfaces of the eleventh eaves portion 81, the twelfth eaves portion 83, and the 13th eaves portion 85. Then, the rainwater and the like that fall on each eaves portion move downward. The rainwater and the like are finally guided by the upright wall portion (terminal portion) 85b of the 13th eaves portion 85, so that they do not contact the back surface of the guide rail 1.

[0065] According to the above configuration, the following effects can be obtained.

[0066] According to such a configuration, the following effects can be obtained.

[0067] (1) The extending direction of the groove 61 for guiding the ascending cable 31 toward the upper part of the slider 3 is: in a state where the wire type adjuster is assembled to the vehicle, a direction intersecting the falling direction R of rainwater and the like indicated by the arrow.

[0068] In addition, the first eaves portion 71 and the twelfth eaves portion 83 are formed such that: in a state where the wire type adjuster is assembled to the vehicle, the upper end portion of the first eaves portion 71 or the upper end portion of the twelfth eaves portion 83 overlaps with the opening 61a of the groove 61, so that the opening 61a of the groove 61 cannot be seen from above the slider 3. Thus, it is possible to suppress the intrusion of rainwater and the like from the opening 61a of the groove 61 into the ascending wire end storage portion (cable assembly portion) 57. Therefore, it is possible to suppress the intrusion of rainwater and the like into the ascending wire end storage portion 57 and to suppress the attachment of rainwater and the like to the ascending cable 31 and the guide rail 1. Thus, it is possible to suppress the freezing of rainwater and the like inside the ascending wire end storage portion 57 at low temperatures, which may cause malfunction of the wire type adjuster, and to suppress the rusting of the ascending cable 31 and the guide rail 1. As a result, it is possible to suppress the occurrence of malfunction of the wire type adjuster and other defective conditions.
