Abstract

(57) [Abstract] [Purpose] A door window regulator in which a carrier plate supporting the lower end of a door glass 1 whose front and rear ends are guided by a sash moves up and down along a guide rail 7 to raise and lower the door glass 1. In the above, the deterioration of operability due to the variation of parts is prevented. [Structure] The carrier plate has two members, one member 25 supports the door glass, and the other member 35 is fitted to the guide rail 7. A long hole 37 in the front-rear direction is formed in one of the members 35, a rod 33 having a circular cross section is provided in the other member 25, and the rod 33 is passed through the long hole 37. The rod 33 can move with respect to the long hole 37 in the longitudinal direction of the long hole 37 and the longitudinal direction of the rod 33, that is, the front-rear direction and the left-right direction of the automobile. This movement absorbs variations in parts.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle door window structure, and more particularly to a structure that does not cause a problem even if there are variations in parts.

[0002]

[Prior Art]

 A conventional door window regulator will be described with reference to FIGS. 5 and 6. FIG. 5 is an exploded perspective view showing a schematic structure of the door window regulator. FIG. 6 is a front view of FIG.

A carrier plate 5 supports the door glass 1 via glass holders 3 attached to two places at the lower end of the door glass 1. The carrier plate 5 can move up and down along the guide rail 7. The carrier plate 5 is pulled upward or downward by a wire 9 running inside the guide rail 7, and the wire 9 is wound by a handle 11 or by a motor (not shown), so that the door is closed. The elevating operation of the glass 1 is performed. As shown in FIG. 6, sashes 13 are provided at the front and rear ends of the door glass 1 to guide the door glass 1.

[0004]

[Problems to be solved by the device]

 However, when the components such as the door glass 1, the sash 13, the guide rail 7 and the like are fluctuated, the locus 15 of the door glass 1 that moves up and down and the locus 17 of the regulator, that is, the carrier plate 5 may not match. That is, as shown in FIG. 6, there are cases in which the trajectories 15 and 17 of the two differ in the front-rear direction of the vehicle, and in the left-right direction of the vehicle as shown in FIG. In such a case, raising and lowering operations are not smooth, which causes abnormal noise, and in addition, a large operating force is required, which is inconvenient.

The present invention has been made in order to solve the above-mentioned object, and even if there are variations in parts, it is easy to absorb the variations and make the traces of the door glass and the regulator coincide with each other. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 The present invention has been made to achieve the above object, and the carrier plate supporting the lower end of the door glass whose front and rear ends are guided by the sash moves up and down along the guide rails. In a door window regulator that raises and lowers the door glass, the carrier plate is used as two members, one member supports the door glass, and the other member is fitted to a guide rail, and one of the members moves in the front-back direction. This is a door window regulator structure in which a long hole is formed and a rod having a circular cross section is provided in the other member to penetrate the long hole, and the diameter of the rod is substantially the same as the vertical diameter of the long hole.

[0007]

[Action]

 The rod can move in the longitudinal direction of the long hole and the longitudinal direction of the rod with respect to the long hole, that is, it can absorb variations in parts in the front-rear direction and the left-right direction of the automobile.

The reason why the loci of the door glass and the regulator do not coincide with each other and the operating force becomes large due to the variation of the conventional parts is that there is no degree of freedom between the door glass and the regulator and the variation cannot be absorbed. there were. According to the present invention, since this variation can be absorbed, a small operation force will suffice.

[0009]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an exploded perspective view showing a general outline of the structure of the present invention. A front view of the main part of FIG. 1 is shown in FIG. The AA cross section of FIG. 2 is shown in FIG. The BB cross section of FIG. 2 is shown in FIG.

The front and rear ends of the vehicle, that is, the left and right ends in the figure, of the door glass 1 are guided by sashes so that the door glass 1 can move up and down. Round holes 21 are opened at two locations at the lower end of the door glass 1, and the glass holder 3 supports the lower end of the door glass, and at the same time, the cylindrical portion 23 of the glass holder 3 is pushed into the hole 21. From above, the first carrier plate 25 is stacked with the holes 27 aligned. In this state, the screw 29 is pushed in, the tip of the cylindrical portion 23 is enlarged (FIG. 3), and the door glass 1 is supported. Further, a rod 33 having a circular cross section is provided in the other pair of holes 31 provided in the first carrier plate 25. Then, a pair of elongated holes 37 are formed in the second carrier plate 35, and one end of this rod 33 is inserted. The diameter of the rod 33 is substantially the same as the vertical diameter of the elongated hole 35, and there is no rattling in the vertical direction. However, it can move in the longitudinal direction of the long hole 35, that is, in the longitudinal direction of the vehicle. The rod 33 has a sufficient length so that it can move in the longitudinal direction of the rod 35 with respect to the long hole 35.

As shown in FIG. 4, the second carrier plate 35 has a groove 39 substantially similar to the conventional one and is fitted to the guide rail 7. That is, both the guide rail 7 and the groove 39 are substantially U-shaped in cross section, and the ends of the U-shape have extension portions 41 and 43 extending in the direction of closing each other so that the fitting is performed. It is difficult to slip in the closed state. A wire 9 (see FIG. 1) is passed through the inside of the guide rail 7 so as to pull the second carrier plate 35 upward or downward. The wire 9 is wound by a handle 11 or a motor and sent out.

The operation of this embodiment will be described below. When the second carrier plate 35 is pulled by the handle 11 or the motor via the wire 9, the second carrier plate 35 moves in the vertical direction along the guide rail 7. Along with this movement, the door glass 1 also moves vertically via the first carrier plate 25. At this time, even if there is a discrepancy in the trajectory between the door glass 1 and the regulator (the guide rail 7 or the second carrier plate 35 in this embodiment), the parts collide with each other as in the conventional case. It does not become difficult to move, and the rod 33 moves to the long hole 37 in the longitudinal direction of the long hole 37 (front and rear direction of the vehicle) or in the long direction of the rod 33 (left and right direction of the vehicle) and escapes, causing collision of parts. You can avoid it. In this way, variations in parts can be absorbed, so to speak, so that the door glass 1 can be smoothly moved up and down. As a result, the operating force by the handle 11 or the motor is small, and no abnormal noise is generated.

Furthermore, vibrations due to wind pressure or the like input to the door glass 1 are less likely to be transmitted from the first carrier plate 25 to the second carrier plate 35 because the rod 33 can move with respect to the elongated hole 37, and therefore It is possible to reduce the generation of sound in the car interior.

[0014]

[Effect of the device]

 As described above, according to the structure of the door window regulator of the present invention, the carrier plate is used as the two members to absorb the variation of the parts in the front-rear direction and the left-right direction of the vehicle. Therefore, the door glass caused by this variation It is possible to prevent the operating force of the door glass from increasing due to the disagreement between the trajectory of the and the regulator. It is also effective in preventing abnormal noise during operation.
