Description

[Detailed description of the invention] (Industrial field of application) The invention is an automotive window regulator,
In particular, the present invention relates to an improvement in the structure for mounting the winding drum of the driving means.

(Prior art and its problems) As a vehicle window regulator, from the viewpoint of reducing size and weight, instead of the conventional arm type, a drive device and a window glass support bracket are connected with a wire, and the drive device is connected with a wire. A wire-type window regulator has been proposed that opens and closes the window glass by winding the wire on a winding drum of the device, unwinding it, and slidingly guiding the window glass support bracket to the guide means. .

The winding drum of the driving means of such a window regulator is fixed with bolts through bolt holes drilled in the inner panel, but it is difficult to assemble the winding drum and fix the winding drum. It has a structural defect in that bolts are used on both sides.

(Purpose of the invention) The object of the invention is to solve these problems and provide a structure in which the winding drum can be assembled and fixed at once using mounting bolts.

Therefore, it is necessary to use mounting bolts to both assemble the winding drum and fix the winding drum, but the bolt fixing methods proposed in the past (for example, Utility Model Publication No. 30-1319) are different from each other. This is a very troublesome method of fitting a tubular nut into a bolt and driving it into a mounting hole, so it is not suitable as a method to achieve the above purpose, and the drum case and case cover can be easily temporarily attached. However, it is necessary to securely attach and secure the drum case to the inner panel.

(Structure of the invention) Therefore, in the present invention, when attaching the winding drum part of the drive means to the door inner panel with bolts, the holes of the bolts are inserted into the bolt insertion holes drilled in the winding cover side. A plurality of elastic protrusions that are slightly larger than the bolt diameter and slightly smaller than the thread of the bolt are provided at intervals in the circumferential direction and protrude in the radial direction to substantially reduce the diameter of the bolt insertion hole, and the bolt is inserted into the bolt insertion hole. This was done based on the fact that it is a good idea to fix the take-up drum cover to the drum case by inserting the protrusion into the thread groove and fixing the take-up drum cover to the drum case. A winding drum cover member 13 is integrally attached to the door inner panel side joint surface of the mounting portion of the drum case, which is fixed to the door inner panel using the mounting bolts B3. The mounting bolt B3 inserted from the recess 12a of the cover member 13 is inserted into the bolt insertion hole 13a formed in the cover member 13 with elastic protrusions S slightly larger than the root diameter of the bolt and slightly smaller than the thread of the bolt at intervals in the circumferential direction. By providing a plurality of protrusions protruding in the radial direction at a distance of 13a to substantially reduce the diameter of the bolt insertion hole, the projections are engaged with the thread groove of the mounting bolt B3 inserted into the bolt insertion hole 13a, and the protrusion is wound up. The drum cover member 13 is temporarily fixed to the drum case and can be assembled to the door panel as it is.

(Effect of the invention) According to the invention, the wire transmits the rotational drive of the drive means to the glass support means through the wire means, and slides and guides the glass support means with respect to the guide means to open and close the window glass. When adopting a type window regulator for the purpose of reducing size and weight, it is possible to assemble the winding drum of the driving means by simply inserting bolts and at the same time fix it to the inner panel via the bolts. Therefore, the workability of installing the window regulator can be significantly improved.

(Embodiment) Hereinafter, a window regulator installed according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, this window regulator extends almost vertically inside a side door of an automobile, and a guide rail 1 (guide means) is attached to the guide rail 1. The glass G is supported by a support bracket 4 (glass support means), and is moved by an upper pulley slider UG and a lower slider by a hand-crank drive means D provided inside the side door.
Wire W stretched on guide rail 1 by DG
Normally, the support bracket 4 is slid along the guide rail 1 by turning it counterclockwise in the upward direction and by turning it clockwise in the downward direction.
As a whole, the guide rail 1, the glass support bracket 4 that slides on the guide rail 1, the wire W that drives and connects the drive means D, and the drive means D are approximately in an inverted L shape. The drive means D can be placed at desired positions horizontally, vertically, and above the guide rail 1 via a wire W.

Specifically, the guide rail 1 is attached to the side door of an automobile via an upper bracket 2 and a lower bracket 3 by bolts B1 and B2 so as to extend substantially vertically, while the driving means D is attached to the side door via an upper bracket 2 and a lower bracket 3 so as to extend substantially vertically. However, in the present invention, when assembling the drive means D, as shown in FIG. The head of B3 is inserted and the cover 13 is fixed, but for such fixing,
As shown in FIG. 5, a plurality of elastic protrusions S, which are slightly larger than the root diameter of the mounting bolt B3 and slightly smaller than the screw thread of the bolt, are provided in the circumferential direction of the bolt insertion hole 13a. By inserting the mounting bolt B3 into 13a, the protrusion is engaged with the thread groove, and the cover 13 can be fixed to the case 12 (see FIG. 5). The drive means D assembled in this manner is then attached to the inner panel via the attachment bolt B3.

Claims (1)

[Claims for Utility Model Registration] A window regulator that transmits the rotational drive of a drive means to a glass support means via a wire means, and slides and guides the glass support means with respect to a guide means to open and close a window glass. In the controller, the winding drum case 12 of the drive means is attached to and fixed to the door inner panel using a plurality of mounting bolts B3, and is integrated into the door inner panel side joint surface of the mounting portion. Attach the winding drum cover member 13 to the drum case 12, and insert the mounting bolts B3 inserted from the recesses 12a of the drum case 12 into the bolt insertion holes 13a formed in the cover member 13 so that the elastic protrusions S are spaced apart in the circumferential direction. A plurality of mounting bolts are provided to protrude in the radial direction, and are inserted into the bolt insertion hole 13a by substantially reducing the diameter of the bolt insertion hole 13a, which is slightly larger than the root diameter of the bolt and slightly smaller than the thread of the bolt. A window regulator for an automobile, characterized in that the protrusion is engaged with the screw groove of B3, the winding drum cover member 13 is temporarily fixed to the drum case, and the winding drum cover member 13 can be assembled to the door panel as it is.
