Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window glass lifting device that opens and closes by sliding up and down at a mounting portion, and is used for automobile windows.

"Prior Art" Examples of conventional technologies include those shown in FIGS. 10 and 11, for example.

That is, it is assumed that the lifting device B attached to the door A, which is the mounting part, is inserted and assembled into the space between the inner panel A1 and the outer panel A2 of the door A through the work hole A3 made in the inner panel A1. For this reason, it is difficult to make the lifting device B into a unit with high window glass support rigidity.Moreover, it requires a large working hole A3 in the inner panel A1, so the rigidity of the door A is reversed. This tends to lead to a decline in Further, since it is inserted through the working hole A3, there are few restrictions on the thickness, and there was no problem even if the drive shaft B2 protruded largely from the drive portion B1.

In order to support the window glass with high rigidity, it is effective to use two guide rails and set up a frame-shaped base member. Difficult to insert inside. It is conceivable to insert the lifting device through the window glass insertion groove A4 formed between the inner panel A1 and the outer panel A2, but in that case, if the drive shaft B2 protrudes significantly, it will not fit into the window glass insertion groove A4. Drive part B1
Since the drive unit B1 cannot be passed through, it has been proposed that the drive unit B1 be constructed so that it can be separated, and that the parts be brought into the door A and assembled inside.

``Problems to be Solved by the Invention'' However, in such conventional window glass lifting devices, the drive section has a split structure, so the durability is significantly lower than when it is integrated. To solve this problem, the rigidity must be increased excessively, leading to an increase in weight, and even more problematic is the split structure, so the drive section that was separated during assembly must be assembled inside the narrow door A. This often requires extra work and complicates the process.
Moreover, since the increased number of parts must be manufactured and managed separately, there is a problem in that the overall cost inevitably increases.

The present invention has been made by focusing on such conventional problems, and provides a window glass lifting device that solves the above problems by allowing any part of the lifting device to pass through the window glass insertion groove of the mounting part. is intended to provide.

``Means for Solving the Problems'' The gist of the present invention to achieve the above object is to provide a windowpane lifting device that is slidably supported by a mounting portion along the up and down locus of the windowpane. A base member is formed by integrally solidifying a pair of guide rails arranged in parallel with each other, and a drive cable is routed around the base member so that at least one of the guide rails has a portion along the guide rail, and A carrier plate fixed to glass and slidably fitted to the guide rail is fixed to the drive cable, while an end of the drive cable is connected to the drive part via a flexible outer tube. The thickness of the base member on which the parts are mounted is set to a thickness that allows it to pass through the window glass insertion groove of the mounting part, and the width of the drive unit in the direction perpendicular to the drive shaft is set so that it can pass through the window glass insertion groove. A window glass lifting device is characterized in that the window glass is set to such an extent that it can pass through the groove.

"Function" Then, while inserting the base member with the parts attached inside through the window glass insertion hole of the mounting part,
By changing the direction of the driving part as appropriate and passing the same through the window glass insertion groove, the whole can be brought into the mounting part from the window glass insertion groove.

The thickness t of the base member 20 on which the parts are mounted is set to be smaller than the opening width b of the window glass insertion groove A4 formed between the inner panel A1 and the outer panel A2 of the door A.

As shown in FIGS. 4 to 6, the drive unit 40
A winding member 42 of the drive cable 11 is rotatably supported on a base plate 41, a winding pulley 43 of the winding member 42 projects from one side of the base plate 41, and a drive shaft 44 projects from the other side. A manual handle 45 or an actuator as shown in FIG. 3 is connected to the drive shaft 44.

The base plate 41 of the drive unit 40 is formed into an elongated shape as a whole, and its width a perpendicular to the drive shaft 44 of the drive unit 40 is about the diameter of the winding pulley 43 and smaller than the opening width b of the window glass insertion groove A4. It is set so that parts etc. do not protrude beyond its width, and has a mounting surface portion 41a that comes into contact with the inner panel A1 of the door A.
A has a bar ring screw hole 4 into which the mounting bolt is screwed.
