Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when the carrier plate moves or is in a constrained state at the moving end, etc., when the tension of the cable acts on the guide rail, the guide rail may tilt with respect to the drum housing due to the play between the drum housing and the guide rail. Also, there was a problem that it was difficult to insert the end of the long guide rail member into the drum housing during assembly.

[0005] The present invention aims to provide an object moving device and a window regulator that can be easily assembled and can suppress the tilting of a guide rail when cable tension acts on the guide rail. [Means for solving the problem]

[0006] The object moving device of the present invention comprises a moving member, a guide rail, a cable, a drum, a drum housing, and a direction changing member. The moving member is to which the object to be moved is attached. The guide rail extends in the direction of movement of the object to be moved and has a first end in the longitudinal direction and a second end located on the opposite side of the first end in the longitudinal direction, and slidably engages with the moving member. The cable is connected to the moving member. The drum winds up or unwinds the cable so that the moving member moves along the guide rail. The drum housing houses the drum. The direction changing member changes the routing direction of the cable. The drum housing has an insertion part and a tilt prevention part. The insertion part is into which the first end of the guide rail is inserted. The tilt prevention part extends from the insertion part toward the second end and prevents the guide rail from tilting. The tilt prevention part is positioned between the cable portion that is outside the guide rail and located between the direction changing member and the drum, and the guide rail, in the width direction perpendicular to the depth direction of the insertion part.

[0007] The window regulator of the present invention comprises a drive unit, a carrier plate, a guide rail, a cable, a drum, a drum housing, and a direction changing member. The carrier plate holds the window glass. The guide rail extends in the direction of movement of the carrier plate and has a first end in the longitudinal direction and a second end located on the opposite side of the first end in the longitudinal direction, and guides by slidably engaging with the carrier plate. The cable is connected to the carrier plate. The drum, driven by the drive unit, winds or unwinds the cable so as to move the carrier plate along the guide rail. The drum housing houses the drum. The direction changing member changes the routing direction of the cable. The drum housing has an insertion part and a tilt prevention part. The first end of the guide rail is inserted into the insertion part. The tilt prevention part extends from the insertion part toward the second end and prevents the guide rail from tilting. The tilt prevention section is positioned between the cable portion of the cable located outside the guide rail and between the direction changing member and the drum, in the width direction perpendicular to the extension direction of the insertion section, and the guide rail. [Effects of the Invention]

[0008] According to the present invention, it is possible to suppress the tilting of the guide rail when the carrier plate is moving or restrained at the moving end, and to provide an object moving device and a window regulator that can be easily assembled. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0010] Below, a window regulator will be described as an example of an object moving device according to the present invention, with reference to the drawings. Note that the embodiments shown below are merely examples, and the object moving device and window regulator are not limited to the embodiments described below.

[0011] (Overview of Window Regulator 1) The window regulator 1 is disposed on the door panel of the vehicle door. The window regulator 1 is a mechanism for moving the window glass W (an example of a moving object) of the vehicle up and down. FIG. 1 is a view seen from the outside of the vehicle with the window regulator 1 attached to the vehicle. FIG. 2 is a view seen from the inside of the vehicle with the window regulator 1 attached to the vehicle. In FIGS. 1 and 2, the vertical direction is indicated by A. In the vertical direction A, the upward direction is indicated by arrow A1, and the downward direction is indicated by arrow A2. Also, in the front-rear direction B, the front direction is indicated by arrow B1, and the rear direction in the front-rear direction B is indicated by arrow B2.

[0012] As shown in FIGS. 1 and 2, the window regulator 1 includes a guide rail 2, a carrier plate 3 (an example of a moving member), a cable guide 4 (an example of a direction-changing member), a winding / unwinding mechanism unit 5, and cables 6 and 7.

[0013] The guide rail 2 is arranged along the up-and-down direction of the window glass W (only partially shown by a dotted line). The guide rail 2 is a member that guides the carrier plate 3 in the up-and-down direction of the window glass W.

[0014] The carrier plate 3 holds the lower end portion of the window glass W. The carrier plate 3 is engaged with the guide rail 2 and is a member that is slidably guided in the up-and-down direction of the window glass W. The carrier plate 3 moves up and down along the guide rail 2.

[0015] The cable guide 4 changes the routing direction of the cable 6. The cable guide 4 is attached to the upper end of the guide rail 2. In the present embodiment, the direction-changing member is the cable guide 4, but it may be a pulley or the like.

[0016] The winding / unwinding mechanism unit 5 winds and unwinds the cables 6 and 7. The winding / unwinding mechanism unit 5 is disposed at the lower end of the guide rail 2. A drum 11 is provided in the winding / unwinding mechanism unit 5, and the ends of the cables 6 and 7 are connected thereto.

[0017] Cable 6 is a lifting cable for lifting the carrier plate 3. One end of cable 6 is connected to the carrier plate 3. Cable 6 extends upward from the carrier plate 3, is wound around the cable guide 4, and extends downward from the cable guide 4. The other end of cable 6 is connected to the drum 11. The portion of cable 6 from the drum 11 to the cable guide 4 is shown as cable portion 6a. The portion of cable 6 from the cable guide 4 to the carrier plate 3 is shown as cable portion 6b.

[0018] Cable 7 is a lowering cable for lowering the carrier plate 3. One end of cable 7 is connected to the carrier plate 3. Cable 7 extends downward from the carrier plate 3. The other end of cable 7 is connected to the drum 11.

[0019] As cables 6 and 7, known ones in which a plurality of metal strands or resin fiber strands are brought together can be used.

[0020] The winding and unwinding mechanism unit 5 includes a drum 11, a motor 12 (an example of a driving unit), a drum housing 13, and a motor housing 14. The ends of cables 6 and 7 are connected to the drum 11. The drum 11 winds and unwinds cables 6 and 7. The motor 12 rotates the drum 11. The motor 12 is configured to be able to rotate forward and backward and rotates the drum forward and backward. Thereby, the cables 6 and 7 connected to the drum 11 are wound around the drum 11 or unwound from the drum 11. As shown in FIGS. 1 and 2, the motor 12 is provided integrally with the motor housing 14. The output shaft (not shown) of the motor 12 is connected to the drum 11 via a speed reduction mechanism (not shown) arranged in the motor housing 14 and rotates the drum 11. The drum housing 13 houses the drum. The drum housing 13 and the motor housing 14 are fastened by fastening members such as bolts.

[0021] (Guide rail 2) The guide rail 2 supports the carrier plate 3 so that it can be raised and lowered. Figure 3(a) is a perspective view showing the guide rail 2. Figure 3(b) is a cross-sectional view between E and E in Figure 3(a). In Figures 3(a) and 3(b), the vehicle width direction C is shown perpendicular to the vertical direction A and the longitudinal direction B. Within the vehicle width direction C, the inward direction with the window regulator 1 attached to the vehicle is indicated by arrow C1, and the outward direction is indicated by arrow C2.

[0022] As shown in Figures 1 and 2, the guide rail 2 generally extends in the vertical direction A, but when mounted on a vehicle, the extension direction of the guide rail 2 is inclined with respect to the vertical direction A. The guide rail 2 is mounted on a vehicle such that the upper end 2a (an example of the second end) shown in Figure 3(a) is located further back B2 than the lower end 2b (an example of the first end). The extension direction of the guide rail 2 is indicated by D, with the upward extension direction D indicated by arrow D1 and the downward extension direction indicated by arrow D2.

[0023] As shown in Figures 3(a) and 3(b), the guide rail 2 has a rail body portion 20 (an example of a base portion), a first vertical wall portion 22, an extension portion 23, and a second vertical wall portion 21.

[0024] The rail body portion 20 is a plate-shaped portion arranged parallel to the longitudinal direction B. The rail body portion 20 extends in the extension direction D. The rail body portion 20 is curved so as to bulge outward in the outward direction C2. The rail body portion 20 has an end 20a on the forward direction B1 side and an end 20b on the rearward direction B2 side in the longitudinal direction B. The surface of the rail body portion 20 on the outward direction C2 side is shown as 20c, and the surface on the inward direction C1 side is shown as 20d.

[0025] The second vertical wall portion 21 is positioned at the end 20a of the rail body portion 20 in the front-rear direction B (an example of the width direction). The second vertical wall portion 21 extends outward from the end 20a of the rail body portion 20 toward the outward direction C2. The second vertical wall portion 21 is positioned perpendicular to the rail body portion 20.

[0026] The first vertical wall section 22 is located at the end 20b. The first vertical wall section 22 extends outward from the end 20b towards the C2 direction. The first vertical wall section 22 is positioned perpendicular to the rail body section 20. The first vertical wall section 22 is positioned opposite the second vertical wall section 21 in the front-rear direction B.

[0027] The extension portion 23 extends from the first vertical wall portion 22 in the front-rear direction B, opposite to the rail body portion 20. The extension portion 23 extends from the end of the first vertical wall portion 22 on the outward direction C2 side toward the front direction B1. The extension portion 23 is formed parallel to the rail body portion 20.

[0028] A recess 24 is formed by the first vertical wall portion 22, the rail body portion 20, and the second vertical wall portion 21. The fitting portion 31 of the carrier plate 3, which will be described later, fits into the recess 24.

[0029] (Carrier plate 3) Figure 4 is an enlarged view of the vicinity of carrier plate 3 in Figure 2. Figure 5 is a cross-sectional view of the FF in Figure 4.

[0030] The carrier plate 3 has the window glass W attached to it and moves along the guide rail 2. As shown in Figure 5, the carrier plate 3 has a fitting portion 31 and a side wall portion 32.

[0031] The fitting portion 31 fits into a recess 24 formed by the rail body portion 20, the first vertical wall portion 22, and the second vertical wall portion 21 of the guide rail 2. The side wall portion 32 is positioned on the front B1 side of the fitting portion 31. The side wall portion 32 forms a fitting groove portion 33 between itself and the fitting portion 31. The first vertical wall portion 22 and the extension portion 23 of the guide rail 2 fit into the fitting groove portion 33.

[0032] The fitting groove 33 includes a first groove 331 and a second groove 332. The first groove 331 is formed along the vehicle width direction C. The first groove 331 has an opening in the inward direction C1. The first vertical wall portion 22 of the guide rail 2 is positioned in the first groove 331. The second groove 332 is formed from the outward end C2 side of the first groove 331 toward the forward direction B1. The extension portion 23 of the guide rail 2 is positioned in the second groove 332.

[0033] The rail body portion 20 is positioned on the inward C1 side of the fitting portion 31. The rail body portion 20 is exposed on the inward C1 side. The second vertical wall portion 21 of the guide rail 2 is positioned on the rearward B2 side of the fitting portion 31. The second vertical wall portion 21 is exposed on the rearward B2 side.

[0034] (Drum housing 13) Figure 6 is an enlarged view showing the vicinity of the winding / unwinding mechanism 5 in Figure 1. Figure 7 shows the drum housing 13 and guide rail 2 with the motor housing 14 removed from the winding / unwinding mechanism 5 in Figure 6. Figure 8 is an exploded view of the guide rail 2 and drum housing 13. Figure 9(a) is a cross-sectional view between GG in Figure 7. Figure 9(b) is Figure 9(a) with the guide rail removed.

[0035] As shown in Figures 7 and 8, the drum housing 13 includes a housing body 51, a rail insertion portion 52 (see Figure 8), an inner protrusion portion 53, and a tilt prevention portion 54.

[0036] As shown in Figure 7, the housing body 51 has a cylindrical space called a drum storage section 511, a plurality of fastening sections 512, and an upper surface section 513. The drum 11 is housed in the drum storage section 511. Each of the plurality of fastening sections 512 has a through hole. As shown in Figure 6, fastening sections 141 with through holes are also provided at the positions of each fastening section 512 on the motor housing 14, and the motor housing 14 and the drum housing 13 are assembled by inserting bolts into the fastening sections 512 and 141. As shown in Figure 7, the upper surface section 513 is located above the drum storage section 511. As shown in Figure 8, a rail insertion section 52 is formed from the upper surface section 513.

[0037] The rail insertion section 52 is an insertion hole into which the end 2b of the guide rail 2 is inserted. As shown in Figure 8, the rail insertion section 52 is formed extending downward D2 from the upper surface 513 of the housing body 51. At the end of the rail insertion section 52 extending downward D2, a lower end surface 525 is positioned perpendicular to the extension direction D. When attaching the drum housing 13 to the guide rail 2, as shown by arrow K in Figure 8, the end 2b of the guide rail 2 is inserted into the rail insertion section 52 and moved downward D2 relative to the drum housing 13. As shown in Figure 7, the guide rail 2 is inserted into the rail insertion section 52 until the end 2b of the guide rail 2 is restricted by the lower end surface 525.

[0038] As shown in Figures 9(a) and 9(b), the rail insertion section 52 has a first insertion section 521, a second insertion section 523, a third insertion section 524, and a fourth insertion section 522. The first insertion section 521 is formed along the front-rear direction B. The rail body section 20 of the guide rail 2 is inserted into the first insertion section 521.

[0039] The second insertion section 523 is formed extending outward from the front B1 end of the first insertion section 521 towards the outward C2 direction. The first vertical wall section 22 of the guide rail 2 is inserted into the second insertion section 523. The third insertion section 524 is formed extending forward from the outward C2 end of the second insertion section 523 towards the front B1 direction. The extension section 23 of the guide rail 2 is inserted into the third insertion section 524. The fourth insertion section 522 is formed extending outward from the rear B2 end of the first insertion section 521 towards the outward C2 direction. The second vertical wall section 21 of the guide rail 2 is inserted into the fourth insertion section 522.

[0040] As shown in Figure 8, the inner projection 53 extends upward in the direction D1 from the upper surface 513. The inner projection 53 guides the guide rail 2 into the rail insertion section 52 when the guide rail 2 is inserted into the rail insertion section 52. The inner projection 53 is located on the edge of the rail insertion section 52 on the inward direction C1 side of the upper surface 513. The inner projection 53 is located along the front-rear direction B as shown in Figures 9(a) and 9(b).

[0041] Figure 10 is a perspective view from above of the vicinity of the inner protrusion 53 and the tilt prevention portion 54 of the drum housing 13. As shown in Figure 10, the inner wall 515 of the housing body 51 that forms the first insertion portion 521 is located on the inward C1 side of the first insertion portion 521. The inner wall 515 is connected to the inner protrusion 53. The inner protrusion 53 is formed such that the inner wall 515 extends upward D1. If the surface of the inner wall 515 and the inner protrusion 53 on the first insertion portion 521 side is called 516, then two protrusions 517 are provided on surface 516. As shown in Figure 9(a), the protrusions 517 restrict the movement of the rail body portion 20 toward the inward C1 side.

[0042] As shown in Figure 8, the tilt prevention section 54 extends upward in the extension direction D1 from the upper surface section 513. The tilt prevention section 54 prevents the guide rail 2 from tilting (in the direction of arrow H in Figure 6). When the drum housing 13 is attached to the guide rail 2, the tilt prevention section 54 faces the second vertical wall section 21, as shown in Figures 6 and 7. As shown in Figure 6, the tilt prevention section 54 is positioned between the cable portion 6a of the cable 6, which is outside the guide rail 2 and located between the cable guide 4 and the drum 11, and the guide rail 2 in the width direction perpendicular to the extension direction D2 (an example of the depth direction of the insertion section). This width direction indicates the width direction of the guide rail 2 and the rail insertion section 52, and is perpendicular to both the extension direction D and the vehicle width direction C.

[0043] The tilt prevention section 54 guides the guide rail 2 into the rail insertion section 52 when the guide rail 2 is inserted into the rail insertion section 52. As shown in Figure 10, the tilt prevention section 54 is positioned on the rearward B2 side edge of the rail insertion section 52 on the upper surface 513. As shown in Figures 9(a) and 9(b), the tilt prevention section 54 is positioned along the vehicle width direction C. The inward C1 side end of the tilt prevention section 54 is connected to the rearward B2 side end of the inner projection section 53. The inner projection section 53 and the tilt prevention section 54 are formed in a substantially L-shape in a plan view along the extension direction D.

[0044] As shown in Figure 10, the inner wall 518 of the housing body 51 that forms the fourth insertion portion 522 is located on the rearward B2 side of the fourth insertion portion 522. The inner wall 518 is connected to the tilt prevention portion 54. The tilt prevention portion 54 is formed by the inner wall 518 extending upward D1. The tilt prevention portion 54 forms the second insertion portion 523 and extends upward D1 further than the inner wall 553 located on the frontward B1 side of the second insertion portion 523. If we call the surface of the inner wall 518 and the tilt prevention portion 54 on the fourth insertion portion 522 side 519, then a projection 520 is provided on surface 519. As shown in Figure 10, the projection 520 restricts the movement of the second vertical wall portion 21 toward the rearward B2 side, as shown in Figure 9(a). As shown in Figure 9(a), the inner wall 551 of the housing body 51 forming the fourth insertion portion 522 is located on the forward B1 side of the fourth insertion portion 522. A projection 552 is provided on the inner wall 551, and the projection 552 faces the projection 520. The projection 552 restricts the movement of the fourth insertion portion 522 toward the forward B1 side.

[0045] (Positional relationship between carrier plate 3 and drum housing 13) Figure 11 shows the carrier plate 3 in its lowest position. As shown in Figure 11, a portion of the carrier plate 3 overlaps with the drum housing 13 in the vehicle width direction C. Figure 12 is a cross-sectional view between JJ showing the carrier plate 3, guide rail 2, and drum housing 13 in Figure 11.

[0046] As shown in Figure 12, the side wall portion 32 that forms the fitting groove portion 33 of the carrier plate 3 is located on the front B1 side of the guide rail 2. The tilt prevention portion 54 is located on the rear B2 side of the guide rail 2. As shown in Figure 8, on the opposite side of the tilt prevention portion 54, with the rail insertion portion 52 in between, a notched space S is formed by the inner protrusion portion 53 and the upper surface portion 513. As shown in Figure 11, when the carrier plate 3 is in a downward position, the side wall portion 32 enters the space S.

[0047] Therefore, the carrier plate 3 can be lowered to a position where it overlaps with the inner protrusion 53 and the tilt prevention part 54 in the vehicle width direction C.

[0048] (Features, etc.) In this embodiment, the window regulator 1 has a tilt prevention section 54 that extends from the rail insertion section 52 toward the end section 2a and prevents the guide rail 2 from tilting. The tilt prevention section 54 is positioned between the cable portion 6a of the cable 6, which is outside the guide rail 2 and located between the cable guide 4 and the drum 11, and the guide rail 2, in the width direction perpendicular to the downward extension direction D2 (an example of the depth direction of the insertion section).

[0049] This prevents the guide rail 2 from tilting relative to the drum housing 13 due to the tension of the cable 6. In addition, when attaching the guide rail 2 to the drum housing 13 during assembly, the tilt prevention part 54 guides the guide rail 2 into the rail insertion part 52 of the drum housing 13, making assembly easier.

[0050] In the window regulator 1 of this embodiment, the carrier plate 3 is movable along the guide rail 2 until a part of the carrier plate 3 faces the tilt prevention part 54.

[0051] This makes it possible to provide the tilt prevention section 54 without narrowing the range of motion of the carrier plate 3.

[0052] In this embodiment of the window regulator 1, the guide rail 2 can be easily attached to the drum housing 13 by inserting the guide rail 2 into the rail insertion portion 52 of the drum housing 13.

[0053] In the window regulator 1 of this embodiment, the tilt prevention part 54 is connected to the inner wall 518 on the cable portion 6a side of the fourth insertion part 522.

[0054] This prevents the guide rail 2 inserted into the drum housing 13 from tilting.

[0055] In the window regulator 1 of this embodiment, the tilt prevention section 54 is formed such that its inner wall 518 extends in the upward direction D1. In this way, the tilt prevention section 54 extends in the longitudinal direction of the guide rail 2 more than the inner wall 553 of the second insertion section 523 on the opposite side of the rail insertion section 52 in the front-rear direction B, making it easier to insert the rail insertion section 52 into the guide rail 2 and improving ease of assembly.

[0056] (Other embodiments) Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0057] (A) In the above embodiment, the tilt prevention part 54 and the inner protrusion part 53 are connected, but they do not have to be connected. Also, the inner protrusion part 53 does not have to be provided, and tilting toward at least the cable portion 6a side (direction of arrow H in Figure 6) can be prevented.

[0058] (B) In the above embodiment, the extension portion 23 of the guide rail 2 extends from the first vertical wall portion 22 toward the opposite side of the rail body portion 20, but it may also extend toward the rail body portion 20. In this case, the second groove portion 332 of the carrier plate 3 is also formed toward the opposite side from the above embodiment. That is, the second groove portion 332 is formed from the end of the first groove portion 331 toward the rear B2 direction toward the outer C2 side.

[0059] (C) In the above embodiment, the tilt prevention part 54 is provided with a projection 520, but the projection 520 is not required.

[0060] (D) In the above embodiment, a window regulator 1 that moves a window pane was used as an example of an object moving device, but the present invention is not limited to this, and can be applied to any device that drives an object by winding up and unwinding a cable using a drum. [Industrial applicability]

[0061] The object moving device of the present invention is easily assembled, has the effect of suppressing the tilting of the guide rail during assembly, and is useful for window regulators and the like. [Explanation of Symbols]
