Description

  The present invention relates to a window regulator that raises and lowers a window of a vehicle and an attachment method thereof.

  There has been a window regulator that raises and lowers the window glass of a vehicle. The window regulator typically includes a carrier plate that supports the window glass, a guide rail that supports the carrier plate so that the carrier plate can be raised and lowered, and a drive unit that raises and lowers the carrier plate via a cable. A direction changing member for changing the moving direction of the cable is provided above the guide rail. The carrier plate is connected to a cable hung on the direction changing member, and the drive unit is lifted by pulling the cable.

  Patent Document 1 discloses a window regulator having a stopper. The stopper is provided at the upper end of the guide rail, and when the glass lift table (corresponding to the carrier plate) rises, it collides with the glass lift table to absorb the shock. Furthermore, the window regulator of Patent Document 1 has a structure for finely adjusting the fixed position of the stopper.

  Patent Document 2 discloses a stopper that regulates further movement of the window glass when a part of the link mechanism collides when the window glass is closed in a window regulator that raises and lowers the window glass by the link mechanism. ing.

Japanese Utility Model Publication No. 05-046516 JP 2002-295121 A

  Patent Document 1 describes that the position of the stopper is set so as to obtain an optimal shock absorbing function. In Patent Document 2, it is described that the stopper mechanism restricts the rolling operation of the roller in the state where the window glass is pushed up to the closing position or just before that.

  If the stopper is not set to an appropriate position and the stopper does not function sufficiently, a large restraining force is applied to the window glass and the window frame when the window is closed, causing deflection at each part. This causes a problem that each part is consumed.

  However, it is difficult to optimally set the stopper position with a single window regulator. For example, the optimum position of the stopper differs depending on the tolerance of the fixing position of the window with respect to the carrier plate, the tolerance of the fixing position of the window regulator, the tolerance of the size of the window glass, the tolerance of the dimension of the window frame of the door, and the like. Therefore, in order to set the optimum position of the stopper, it is necessary to adjust the position of the stopper while the window glass is supported by the window regulator and the window regulator is incorporated in the door.

  Conventionally, there has been no technical idea of adjusting the position of the stopper in a state where the window glass is supported by the window regulator and the window regulator is incorporated in the door. For example, in the window regulator of Patent Document 1, when the upper bracket (32) is fixed to the door panel, a portion for adjusting the position of the stopper (screw 34 and long hole 25) is sandwiched between the door panel and the window glass, and the stopper The position of can not be adjusted. Therefore, it is necessary to adjust the position of the stopper before the window regulator is assembled to the door.

  The object of the present invention is to adjust the stopper to an appropriate position even if there is a dimensional tolerance or a fixing position tolerance of other parts such as a window glass, a door, a window frame, etc. To provide a window regulator capable of preventing concentration on a part and a method for mounting the same.

  A window regulator according to an aspect of the present invention includes a guide rail, a carrier plate that moves up and down along the guide rail, a drive unit that rotates the drum, one end connected to the drum, and the other end connected to the carrier. A window regulator comprising a cable connected to a plate, a direction changing member attached to an upper end of the guide rail, a fastening member for fixing the direction changing member to the guide rail, and the guide rail by the fastening member And a stopper fixed to the direction changing member, the stopper contacting a collision portion of the carrier plate and restricting movement of the carrier plate, and the fastening member being temporarily fixed The fastening member sometimes has a long hole through which the fastening member is temporarily fixed, When the carrier plate is lowered, the lowermost end of the restricting portion is positioned below the highest rising position of the collision portion, and when the fastening member is temporarily fixed and the carrier plate is raised most, the restriction The portion is supported by the guide rail so as to be able to move up in contact with the collision portion.

  A method for attaching a window regulator according to one aspect of the present invention is an attachment method for attaching a window glass and the window regulator to a vehicle door, and temporarily attaching the fastening member to attach the window regulator to a door panel. An intermediate member between the window frame of the door of the vehicle and the upper edge of the window glass; and a step of attaching the window glass to the window regulator so as to be movable between a deadline position and a fully open position. A step of interposing and moving the window glass to the closing position, and a step of fixing the fastening member in a state where the interposition member is interposed between the window frame and an upper edge of the window glass.

  According to the present invention, even if there is a dimensional tolerance or a fixing position tolerance of other parts such as a window glass, a door, and a window frame, the stopper is adjusted to an appropriate position so that a large restraining force can be applied between the window glass and the window frame. It is possible to prevent concentration on the part.

  The upper joint member 10 is provided with a fitting hole 106 and a temporary fixing hole 107. Among these, the fitting hole 106 is a hole that fits with the upper end portion of the guide rail 11 as described above.

  The temporary fixing hole 107 is a hole that opens to the bottom surface of the upper joint member 10, allows the upper portion of the stopper 20 to be inserted, and allows the stopper 20 to be temporarily fixed by being pushed upward. The temporary fixing hole 107 is formed adjacent to or continuously with the fitting hole 106 into which the guide rail 11 is fitted. The temporary fixing hole 107 is provided along the bottom surface (the bottom surface of the recess) of the concave guide portion 112 of the guide rail 11 fitted in the fitting hole 106.

  As shown in FIG. 10C, the upper joint member 10 is provided with two ribs 108 a and 108 b that sandwich the temporary fixing hole 107 from the left and right. The ribs 108 a and 108 b can guide the stopper 20 so as to be movable in the longitudinal direction of the guide rail 11, and are formed to extend along the longitudinal direction of the guide rail 11. The distance L1 between the left rib 108a and the right rib 108b is the same or slightly shorter than the lateral width W1 (see FIG. 7A) of the base portion 20A of the stopper 20 excluding the protrusion 23. Has been. Thereby, when the stopper 20 is pushed into the temporary fixing hole 107, the position of the stopper 20 is held and temporarily fixed by the frictional force of the ribs 108a and 108b.

  Tapered portions d1 and d2 are provided at the lower ends of the rib 108a and the rib 108b, respectively. The tapered portions d1 and d2 are provided so that the distance between the right end of the left rib 108a and the left end of the right rib 108b becomes wider as it goes downward. Such a tapered portion d1, d2 makes it easy to define the orientation of the stopper 20 when the stopper 20 is disposed.

  As shown in the range S of FIG. 10C, the taper portions d1 and d2 are stepped from the bottom to the top so that the angle of the taper is once loosened, becomes sharp again, and becomes loose. A portion da (see the enlarged view of FIG. 11) is provided. Here, loose means close to the vertical direction, and sudden means the opposite. The stepped portion da is provided at a position facing each lower end portion of the left and right tapered portions 24 when the temporarily fixed stopper 20 is positioned at the lowermost position. Due to the stepped portion da, the stopper 20 can be stably disposed at the lowest position.

  As shown in FIGS. 10A to 10D, the fastening portion 109 of the stopper 20 is provided with an insertion hole 109 a orthogonal to the bottom surface of the base portion 20 </ b> A of the stopper 20 or the concave guide portion 112 of the guide rail 11. Yes. As shown in FIG. 12, the stopper 20 is inserted into the temporary fixing hole 107 of the upper joint member 10, and the fastening member 101 is the long hole 22, the insertion hole 111 of the guide rail 11, and the insertion hole of the fastening portion 109. 109a is temporarily fixed to the upper joint member 10. A cylindrical collar 102 is fitted into the insertion hole 109 a of the upper joint member 10. The fastening member 101 is passed through the collar 102, and temporarily fixed with a washer 103 for temporary fixing on the tip side.

  The time when the fastening member 101 is passed through the long hole 22 of the stopper 20 and the stopper 20 is at the lowest position is referred to as an initial position when the stopper 20 is temporarily fixed.

  As shown in FIG. 12, the temporary fixing hole 107 of the stopper 20 may be communicated with the through hole of the fastening portion 105. Then, when the stopper 20 is pushed upward, a part of the stopper 20 may be exposed in the through hole of the fastening portion 105. A fastening member (such as a bolt) that fastens the upper joint member 10 to the vehicle door is passed through the fastening portion 105, but the fastening member is fixed to the back of the portion where a part of the stopper 20 is exposed, It is good to comprise so that a fastening member and the stopper 20 may not contact. With this configuration, the position adjustment range of the stopper 20 can be increased without increasing the vertical dimension of the upper joint member 10.

  FIG. 13 is a perspective view showing a state before and after the collision between the stopper and the buffer member, FIG. 13A is a perspective view showing a state before the collision, and FIG. 13B is a perspective view showing a state at the time of the collision. It is.

  Due to the fixing structure of the stopper 20 as described above, as shown in FIG. 13A, when the stopper 20 is in the initial position when temporarily fixed, the lower end of the restricting portion 21 of the stopper 20 is the collision portion of the buffer member 121. 121A is arranged lower than the uppermost position where it can move.

  Therefore, as shown in FIG. 13B, when the carrier plate 12 rises from a predetermined position, the collision part 121 </ b> A of the buffer member 121 collides with the regulation part 21 of the stopper 20 and pushes up the stopper 20. At this time, the protrusions 23 and 23 of the stopper 20 are restrained by the inner wall of the guide rail 11, and the stopper 20 is pushed up while the direction is restricted. In a state where the stopper 20 is pushed up, a nut is screwed to a fastening member such as a bolt inserted into the fastening portion 105 and fixed to the door panel, so that the stopper 20 can be easily attached to the guide rail from the outside of the door panel. Can be fixed to.

<Mounting method of window regulator>
Then, the attachment method of the window regulator 1 of embodiment is demonstrated.

  FIGS. 14 to 16 show the window regulator mounting process. FIG. 14A is a schematic diagram of the first process, FIG. 14B is a schematic diagram of the second process, and FIG. FIG. 15B is a schematic diagram of the fourth process, FIG. 16A is a schematic diagram of the fifth process, and FIG. 16B is a schematic diagram of the sixth process.

  In the attaching process of the window regulator 1, first, as shown in FIG. 14A, the fastening portion 105 of the upper joint member 10 is fastened to a door panel P1 (for example, an inner panel) using fastening members such as bolts. . Further, the fastening portion 131 of the lower joint member 13 is fastened to the panel P1 using a fastening member such as a bolt. Thereby, the window regulator 1 is fastened to the panel P1. At this time, the stopper 20 is in the initial position.

Next, as shown in FIG. 14B, the glass holder 122 attached to the window glass W is fastened to the carrier plate 12 using a fastening member such as a bolt. The fixed window glass W can be moved between the fully open position and the deadline position by raising and lowering the carrier plate 12.
Subsequently, as shown in FIG. 15A, a spacer J1 is attached to the upper edge of the window glass W. The spacer J1 corresponds to an example of an interposition member according to the present invention. The spacer J1 is a member that adds a predetermined thickness (for example, a thickness of about 2 mm) to the upper edge of the window glass W. The spacer J1 may be attached before the window glass W is supported by the carrier plate 12.

  Subsequently, as shown in FIGS. 15B and 16A, the drive unit 14 is driven to raise the carrier plate 12.

  In the ascending process, first, the buffer member 121 of the carrier plate 12 contacts the stopper 20 (see FIG. 15B). At this time, the carrier plate 12 is lower than the movable uppermost position, and the upper edge of the window glass W and the upper end of the spacer J1 do not hit the window frame F (also referred to as a door roof) or the roof inner fastener.

  When the carrier plate 12 further rises, the buffer member 121 of the carrier plate 12 pushes up the stopper 20, and the spacer J1 attached to the window glass W hits the window frame F or the stopper (see FIG. 16A). Thereby, a brake is applied to the rising of the carrier plate 12, and the drive unit 14 detects this and stops.

  An operator fixes the fastening member 101 temporarily fixed to the fastening part 109 with a nut in the stage of Fig.16 (a). The stopper 20, the guide rail 11, the upper joint member 10, the collar 102, the temporary fixing washer 103, and the door panel P <b> 1 are fixed together and fastened to the door of the vehicle. Thereby, the stopper 20 is fixed.

  Then, as shown in FIG.16 (b), the window regulator 1 is driven and the window glass W is dropped. Then, the spacer T1 is removed. Thereby, the attachment of the window regulator 1 and the window glass is completed.

  Next, the operation of the window regulator 1 after completion of attachment will be described.

  FIG. 17 shows the operation of the window regulator 1. FIG. 17 (a) is a schematic diagram showing the state immediately before the window glass rises most, FIG. 17 (b) is an enlarged view of the upper edge portion of the window glass, and FIG. (C) is an enlarged view of the portion of the stopper and the buffer member, FIG. 17 (d) is a schematic diagram showing when the window glass is raised most, FIG. 17 (e) is an enlarged view of the upper edge portion of the window glass, FIG. 17 (f) is an enlarged view of a portion of the stopper and the buffer member.

  As shown in FIGS. 17 (a) to 17 (c), when the window glass W is moved to the closing position, first, the carrier immediately before the upper edge of the window glass W comes into contact with the window frame F to apply pressure. The buffer member 121 of the plate 12 collides with the restricting portion 21 of the stopper 20. Thereafter, as shown in FIGS. 17D to 17F, the buffer member 121 of the carrier plate 12 is pushed by the stopper 20 to exert a braking force on the drive unit 14, and then the upper edge of the window glass W. Collides with the window frame F or the stopper. And the drive part 14 detects this and the drive part 14 stops. At this time, the upper edge of the window glass W is brought into contact with the window frame F with an appropriate pressure, and it is avoided that a large restraining force is applied to the window glass W and the window frame F. The thickness of the spacer J1 is set so that the setting is performed in this way.

  As described above, according to the window regulator 1 and the mounting method thereof according to the embodiment, when the stopper 20 is temporarily fixed and the carrier plate 12 pushes up and moves the stopper 20, the stopper 20 is fastened. In a state where the spacer J1 is removed, the stopper 20 and the carrier plate 13 first come into contact with each other, and then the buffer member 121 is elastically deformed so that the window glass W comes into contact with the window frame F or the roof internal fastener. The stopper 20 can be fixed at the position. The fixed position of the stopper 20 can be adjusted by raising the stopper 20 due to the contact between the restricting portion 21 of the stopper 20 and the collision portion 121A of the carrier plate 12. Therefore, even if there is a dimensional tolerance or a fixing position tolerance of other parts such as the window glass W, the door, and the window frame F, the stopper 20 is adjusted to an appropriate position, and a large restraining force is applied to the window glass W and the window frame. Concentration on the portion F can be prevented.

  Moreover, in the said embodiment, although the buffer member 121 was provided in the part which collides with the stopper 20 of the carrier plate 12, the carrier plate 12 is provided with a collision part with little or no buffer function, and the stopper 20 has a buffer function. It may be provided.

  In addition, the details specifically shown in the embodiments can be changed as appropriate without departing from the spirit of the invention.
