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, and is used, for example, in the window of an automobile door.

``Prior art'' As a conventional window glass lifting device, for example, the
There is one disclosed in Japanese Patent No.-14231.

In other words, the publication states that guide rails are arranged in front and behind the inch panel of the door, which is the mounting part, and the guide plate, which is a carrier for solidifying the window glass and raising and lowering it, can be moved up and down through rollers on each guide rail. What is supported is disclosed.

However, with this conventional technology, the lifting device must be assembled from a state in which each member is disassembled, so the mutual positional relationship between the members is not determined in the assembly section, resulting in an unstable state. It is necessary to determine the positional relationship between each member during installation.

The assembly workability was extremely poor.

Therefore, we created a frame-shaped base member by solidifying the top and bottom of a pair of idle rails with base plates that were installed in parallel along the vertical path of the window glass, and used this base member as a basis for positioning each member during assembly. There are suggestions for things that can be done easily.

"Problems to be Solved by the Invention" However, in such a conventional window glass opening/closing device, if the precision in assembling the guide rail and base plate is poor, the overall precision will be poor, as shown in Fig. 9 ( As shown in a), the guide rail 1.1 may shift vertically, or as shown in FIG. 9(b), the guide rail 1.1
There is a problem in that it is difficult to achieve accuracy because of diagonal deviations, parallel deviations as shown in FIG. 9(C), or combinations of these deviations.

The present invention has been made in view of these conventional problems, and it is an object of the present invention to provide a window glass lifting device that solves the above problems by allowing the base member to be positioned automatically during assembly. The purpose is

"Means for Solving the Problems" The gist of the present invention for achieving the above object is to provide a window glass elevating device that supports a window glass so that it can be slidably opened and closed. A frame-shaped base member is formed by solidifying the upper and lower parts of a pair of kite rails arranged in parallel along a base plate, and a carrier is fitted into at least one of the guide rails so as to be movable up and down. The lower part of the window glass is solidified to allow the window glass to be raised and lowered to open and close, characterized in that the upper and lower base plates and guide rails of the base member are provided with mutually corresponding positioning means. It resides in the device.

"Function" Therefore, the base member that forms the basis of positioning is made up of the upper and lower guide rails connected by base plates, and when configuring the base member, the upper and lower base plates of the base member and the guide rail are connected to each other. By positioning and assembling the base members using a positioning means, the base members can be assembled with extremely high precision.

A dust trap 45 is formed from the L stage to the lower stage of the base plate 40, and a steady rest roller 46 that can be pressed against the window glass B is attached thereto via a support bracket 46a.

A drive base 22 is provided between the intermediate portions of the guide pulleys 30 and 30.
is constructed, and a drive section 50 is installed on this drive base 22. The drive unit 50 includes a motion motor 51. Reduction mechanism 52. A drive pulley 53 is provided.

As can be seen in FIGS. 1 to 3, both ends of the drive base 22 have flanges 23.2 for fastening with the guide rail 30.
4 is newly installed, and positioning holes 23a are installed in the flanges 23° and 24.
, 23b and positioning holes 24a, 24b are formed, and positioning holes 34e, 34f are formed in the bottom wall 34 of the guide rail 30 corresponding thereto.

As can be seen in Figures 3 to 5, the guide rail 30.3
0, a driving side carrier 60 and a driven side carrier 60a, which have the same structure except for a part, move up and down on the guide rail 30 and 30 respectively via a roller unit 70 that is removably fitted to the guide rail 30. It is movably mounted.

The carrier 60 on the drive side includes a carrier plate 61 to which the window glass B is fixed, and a drive plate 62 to which the drive cable 11 is connected. A base is formed by connecting these parts with a roller support part 63. The carrier plate 61 is vertically provided with insertion holes for fastening bolts that fasten the lower end of the window glass B. As shown in FIG.

The drive plate 62 is sent along the surface of the window glass B,
The end of the drive cable 11 that has come down from above and the end of the drive cable 11 that has extended from below are connected to the connection surface 64a of the connection end 64.64 ahead.

When assembling the window glass lifting device 1O having the hill configuration, the guide rails 30.30 are arranged in parallel, the base plates 40.40 are arranged above and below between the guide rails 30.30, and the drive base 22 is placed in the middle between the guide rails 30, 30 to determine the shape of the base member 20.

When assembling, the guide rails 30.30 are attached to the side flanges 41a, 41b of the base plate 40.40.
The bottom walls 34 and 34 of the positioning holes 40a and 40 are brought into contact with each other.
Align the positioning holes 34a and 34b with positioning hole 4
