Description

  The present invention relates to a window regulator device and a manufacturing method thereof.

As a mechanism for raising and lowering a window glass provided on a vehicle door or a vehicle body, for example, a window regulator device having a so-called X arm such as Japanese Patent Application Laid-Open No. 9-119262 and Japanese Utility Model Laid-Open No. 4-24983 is known. . In this type of window regulator device, rail-shaped guide members are provided on the door or body side and the window glass side, respectively, and the main arm and sub arm (equalizer arm) constituting the X arm are slidably attached to each guide member. It has a structure. By the way, a structure for preventing the sliding member (roller) on the arm side from dropping off is required at the end of the guide member. For example, in the above-mentioned Japanese Patent Application Laid-Open No. 9-119262, a stopper portion for preventing the sliding member from coming off is formed by processing the end portion of the guide member. In Japanese Utility Model Laid-Open No. 4-24983, a holder for preventing the sliding member from coming off is attached to the end of the guide member. However, providing such a unique retaining structure such as a stopper and a holder requires much labor and cost for manufacturing, and causes an increase in the size of the guide member. Further, since the guide member and each arm are long members, the manufacturing method in which the sliding member provided on the arm is inserted into the guide member is inefficient and requires a large work space. .

  According to the present invention described above, it is possible to obtain a window regulator device and a method for manufacturing the same that are excellent in workability at the time of manufacture and can be reduced in size and weight as compared with the conventional one.

  FIG. 1 shows a window regulator device 10 manufactured by the manufacturing method of the present invention. First, an outline of the window regulator device 10 will be described. The window regulator device 10 is provided between an inner panel (not shown) and an outer panel (not shown) of the vehicle door 11, and an X arm (elevating / lowering) composed of a main arm 12 and a sub-arm (elevating guide arm, equalizer arm) 13. Mechanism) 14, a driven gear 15 formed integrally with the main arm 12, a motor 16, a first guide member (main bracket) 17, and a second guide member (equalizer bracket) 18. The vehicle door 11 is provided with guide means (not shown) for guiding the window glass 23 so as to be movable up and down in the y direction in FIG.

  The main arm 12 and the driven gear 15 are pivotally supported by a shaft 12p with respect to the vehicle door 11, and rotate about the shaft 12p when a driving force is applied from the motor 16 to the driven gear 15. The intermediate portion of the sub arm 13 is pivotally supported by the shaft 13p at the intermediate portion in the longitudinal direction of the driven gear 15 so as to be relatively rotatable.

  The 1st guide member 17 is being fixed to the lower end part of the window glass 23 in the shape which orient | assigned the longitudinal direction to the direction (same x direction) substantially orthogonal to the raising / lowering direction (y direction of FIG. 1) of the window glass 23. . The second guide member 18 is fixed to the inner panel of the vehicle door 11 with the longitudinal direction thereof substantially parallel to the first guide member 17 (x direction). More specifically, pierce nuts (nut members) 28 are provided at both ends of the second guide member 18, and each pierce nut 28 is screwed with a bolt (not shown) provided on the inner panel side so as to be in the second guide. The member 18 is fixed. Guide rollers 20 and 21 are provided at one end portions of the main arm 12 and the sub arm 13, and the guide rollers 20 and 21 are slidably fitted to the first guide member 17 in the longitudinal direction thereof. A guide roller (sliding member) 22 is provided at the other end of the sub arm 13, and the guide roller 22 is fitted to the second guide member 18 so as to be slidable in the longitudinal direction.

  When the window glass 23 is raised in the window regulator device 10 having the above structure, the main arm 12 is rotated counterclockwise in FIG. Then, the guide roller 20 rises in the y direction while moving in the left direction in FIG. 1 along the guide surface of the first guide member 17. At the same time, the sub arm 13 is rotated about the shaft 13p in the clockwise direction in FIG. 1, and the guide roller 21 moves along the guide surface of the first guide member 17 in the right direction in FIG. The same amount rises in the y direction, and the guide roller 22 is moved in the left direction in FIG. 1 along the guide surface of the second guide member 18. By the operation of the X arm 14 that combines the rotation of the main arm 12 and the sub arm 13, the first guide member 17 is pushed up in the direction away from the second guide member 18, and the window glass 23 is raised. In contrast, when the window glass 23 is lowered, the main arm 12 may be rotated clockwise in FIG. Then, the sub arm 13 is rotated counterclockwise in FIG. 1, the guide roller 20 and the guide roller 21 are moved away from each other along the guide surface of the first guide member 17, and the guide roller 22 is moved to the second guide. It moves rightward in FIG. 1 along the guide surface of the member 18. As a result, the first guide member 17 approaches the second guide member 18 and the window glass 23 is lowered.

  The manufacturing method of the window regulator apparatus 10 which concerns on the characteristic of this invention is demonstrated. In the present embodiment, when the window regulator device 10 is manufactured, the sub arm 13 and the guide roller 22 are prepared as separate members. As shown in FIG. 8, the guide roller 22 has a structure in which a roller shaft portion 22b is inserted into a rectangular tube-shaped sliding portion 22a so as to be relatively rotatable about an axis 22p, and is coaxial with the roller shaft portion 22b. A caulking projection (fastening portion) 22c is provided on the top. The sliding portion 22a has an open portion 22d on the bottom surface side, and has a narrow protruding portion 22e on the upper side opposite to the open portion 22d. A head portion 22f of the roller shaft portion 22b is located in the opening portion 22d. Further, the sub arm 13 is previously formed into a predetermined shape shown in FIG. 1, and a through hole 13a shown in FIG. 8 is formed at one end thereof. In the flowchart of FIG. 12 showing the manufacturing process, the preparation process of the sub arm 13 and the guide roller 22 is shown as step S1.

  Subsequently, the process proceeds to the step S2 in FIG. In this step, the second guide member 18 is formed by the forming apparatus 25 shown in FIG. The forming apparatus 25 includes a tact feed (sequential feed) press forming machine that forms the second guide member 18 while transferring the flat plate-shaped raw material at the M1 position in FIG. 9 in the direction of arrow R. The single-piece second guide member 18 shown in FIG. 5 is completed at the position M2 in FIG. However, as shown in FIG. 10, at the M2 position, the end of the second guide member 18 is connected to the runner 18v. As shown in FIGS. 2 to 6, the molded second guide member 18 is continuous with the bottom surface portion 18a, the pair of opposed guide portions 18b upstanding from both side portions of the bottom surface portion 18a, and the opposed guide portions 18b. It has a pair of retaining portions 18c facing the bottom surface portion 18a, and an area between the pair of retaining portions 18c is opened as an opening 18d. At both ends of the second guide member 18, a disc-shaped nut mounting portion 18e continuous to the bottom surface portion 18a and an insertion guide portion 18f continuous to the pair of retaining portions 18c are formed. A circular through hole 18g penetrating through the bottom surface portion 18a is formed in the bottom surface portion 18a in the vicinity of one nut mounting portion 18e. A through hole 18h is formed at the center of each nut mounting portion 18e.

  When the molding process of the second guide member 18 is completed, the process proceeds to the work process of step S3 in FIG. In this step, the guide roller 22 is inserted into the second guide member 18 using the roller insertion machine 26 provided in the molding apparatus 25 at the position M3 in FIG. In this insertion step, as shown in FIG. 10, the guide roller 22 is inserted so as to slide from the open end of the second guide member 18. More specifically, the width of the sliding portion 22a corresponds to the interval between the pair of opposed guide portions 18b (see FIG. 8), and the end portion of the second guide member 18 is larger than the interval between the pair of opposed guide portions 18b. Since it is opened so that there is no narrow portion (see FIGS. 3 and 5), it is possible to insert the guide roller 22 from the end. The insertion guide portion 18f functions as a guide for facilitating insertion of the guide roller 22.

  After the guide roller 22 is inserted, the process proceeds to step S4 in FIG. In this step, the pierce nut 28 is fixed to the nut attachment portion 18e of the second guide member 18 using the pierce nut attachment machine 27 provided in the molding device 25 at the position M4 in FIG. As shown in FIG. 7, the pierce nut 28 is fixed on the nut mounting portion 18e with the screw hole 28a positioned coaxially with the through hole 18h.

  After the pierce nut 28 is attached, the second guide member 18 is separated from the runner 18v in the state shown in FIGS. 3 and 4 (step S5 in FIG. 12). In this state, the sliding portion 22a of the guide roller 22 can slide in the longitudinal direction of the second guide member 18 while being guided by the bottom surface portion 18a, the opposing guide portion 18b, and the retaining portion 18c. The piercing nut 28 attached to 18e restricts the second guide member 18 from falling off the end. That is, the pierce nut 28 that is a member for fixing the second guide member 18 to the vehicle door 11 also functions as a means for preventing the guide roller 22 from being pulled out. As shown in FIG. 8, the guide roller 22 is prevented from dropping from the opening 18d by the retaining portion 18c.

  Subsequently, the process proceeds to the work process of step S6 in FIG. In this step, the sub arm 13 is attached to the guide roller 22. In this attaching operation, the guide roller 22 is slid in advance to a position overlapping with the through hole 18g. Then, as shown in FIG. 8, the through hole 18g and the open portion 22d of the sliding portion 22a are in communication with each other. Here, a roller support jig (pivoting jig) 30 is inserted into the open portion 22d from the bottom surface side of the second guide member 18 through the through hole 18g, and the roller support jig 30 is inserted into the head portion 22f of the roller shaft portion 22b. To support the guide roller 22. On the other hand, as shown in FIG. 8, the caulking protrusion 22c and the narrow protrusion 22e protrude from the opening 18d, and the end of the sub arm 13 is placed on the narrow protrusion 22e while the caulking protrusion 22c is inserted into the through hole 13a. Placed on. Then, the sub-arm 13 and the roller shaft portion 22b are fixed by caulking the caulking protrusion 22c as shown by a two-dot chain line in FIG. At this time, the force applied by the caulking work of the caulking protrusion 22c is received by the roller support jig 30 instead of the bottom surface portion 18a. Since the roller shaft portion 22b is rotatable relative to the sliding portion 22a, the sub arm 13 pivots relative to the guide roller 22 (sliding portion 22a) when the sub arm 13 and the roller shaft portion 22b are fixed by caulking. It is in a worn state.

  When the unit composed of the sub arm 13, the second guide member 18 and the guide roller 22 (hereinafter referred to as the sub arm unit U for convenience) is completed as described above, the process proceeds to the step S7 in FIG. In this step, the sub arm unit U is attached to the vehicle door 11. Specifically, a bolt (not shown) provided on the inner panel side of the vehicle door 11 is screwed and fixed to a pair of pierce nuts 28 provided on the second guide member 18. Further, the sub arm 13 is pivotally supported by the main arm 12 via the shaft 13p, and the end of the sub arm 13 opposite to the guide roller 22 is slidable on the first guide member 17 via the guide roller 21. Support. Although not shown in detail, the guide roller 21 has the same structure as the guide roller 22, and a part of the guide roller 21 is caulked and fixed to the sub arm 13. In the attaching process of the sub arm unit U, a method of attaching the main arm 12 and the first guide member 17 to the vehicle door 11 side (inner panel and window glass 23) in advance, or the sub arm unit U, the main arm 12, and the first Any method of attaching the guide member 17 to the vehicle door 11 after forming a larger unit by combining the guide members 17 can be employed.

  According to the above manufacturing method, the following effects can be obtained. First, after inserting the guide roller 22 into the second guide member 18, a pierce nut 28 is attached at a position to prevent the second guide member 18 from falling off, and the pierce nut 28 also functions as a means for preventing the guide roller 22 from being removed. I am letting. This eliminates the need for forming a unique retaining means, thereby reducing the work time. In addition, the effective length of the second guide member 18 (sliding amount of the guide roller 22) can be made relatively long, or the second guide member 18 can be made compact by the amount that the original retaining means is not provided. . For example, in a conventional window regulator device, after inserting a roller into the guide member, a claw for preventing the roller is formed near the end of the guide member. However, according to the present embodiment, such a problem can be solved.

  Second, when connecting the sub arm 13 and the second guide member 18 via the guide roller 22, the guide roller 22 which is a small member is first inserted into the second guide member 18, and then the sub arm 13 and the guide Since the rollers 22 are connected by caulking, workability is good. For example, unlike the present embodiment, when the guide roller 22 is inserted into the second guide member 18 after the sub arm 13 and the guide roller 22 are connected first, a large member is used when the guide roller 22 is inserted. A certain sub arm 13 must be moved together, which requires a large work space and takes time and effort, but according to the present embodiment, such a problem can be solved.

  Third, when the sub arm 13 and the guide roller 22 are connected, the roller support jig 30 is inserted through the through-hole 18g to support the guide roller 22. Therefore, when the caulking protrusion 22c is caulked, the second A load is not applied to the guide member 18 (bottom surface portion 18a), and deformation of the second guide member 18 can be prevented. In order to reduce the influence on the strength of the second guide member 18, the formation position of the through hole 18g is set near the end of the second guide member 18, that is, near the end close to one nut mounting portion 18e. ing.

  Fourth, the guide roller 22 and the pierce nut 28 are automatically assembled in order during the tact feed press molding process for molding the second guide member 18, so that these processes are performed separately at different locations. Can save working time and working space.

  As can be understood from the above description of the embodiment, according to the window regulator device and the manufacturing method to which the present invention is applied, the workability at the time of manufacturing is improved as compared with the conventional one, and in addition, the guide member can be reduced in size and weight. It becomes. However, the present invention is not limited to the above embodiment, and can be modified without departing from the gist of the invention.

  For example, in the present invention, the roller inserted into the guide member is not limited to the form of the guide roller 22 described above. FIG. 11 shows another type of guide roller 122. The guide roller 122 is slightly different from the guide roller 22 of the previous embodiment in the shape of the roller shaft portion 122b inserted and supported in the rectangular cylindrical sliding portion 122a. Specifically, the roller shaft portion 122b has a partially spherical outer surface, and is fitted to the sliding portion 122a so as to be relatively rotatable about the axis 122p. The narrow protrusion 122e that protrudes from the opening 18d and supports the end of the sub arm 13 is formed not on the sliding part 122a but on the roller shaft part 122b, and a caulking protrusion 122c is continuously formed on the roller shaft part 122b. Is formed. The bottom surface of the roller shaft portion 122b faces the open portion 122d, and when the caulking projection 122c is caulked, the roller support jig 30 inserted through the through hole 18g contacts and supports the bottom surface of the roller shaft portion 122b. .

  Further, in the guide roller 22 and the guide roller 122, the outer surfaces of the sliding portions 22a and 122a guided by the second guide member 18 are both square, but in the present invention, the outer surface is a circular or spherical type roller. Can also be used. The guide roller 22 and the guide roller 122 have a structure in which roller shaft portions 22b and 122b that can rotate relative to each other are provided inside sliding portions 22a and 122a that do not rotate relative to the second guide member 18. However, it is also possible to employ a roller of a type in which portions corresponding to the roller shaft portions 22b and 122b are directly guided so as to be slidable and relatively rotatable with respect to the guide member.

  In the illustrated embodiment, the present invention is applied to the sub arm 13 and the second guide member 18, but the lifting guide arm and the guide member to which the present invention is applied are not limited thereto. For example, the above embodiment is also applied to the assembly process of the sub arm 13 and the first guide member 17 through the guide roller 21 and the assembly process of the main arm 12 and the first guide member 17 through the guide roller 20. The manufacturing method can be applied.

  Moreover, although the window regulator apparatus 10 of FIG. 1 is the example attached to the vehicle door 11, this invention is applicable similarly not to a vehicle door but to the window regulator apparatus provided in a vehicle body.

It is a side view which shows the state which attached the window regulator apparatus to which this invention was applied to the vehicle door.
