Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an improvement in a window glass lifting device.

``Conventional technology'' Traditionally, for example, in hard-top automobiles without a sash, the window glass lifting device had only one guide rail due to ease of assembly and space limitations, and the window glass was guided by this single guide rail. It was common to have one. (For example, see Japanese Patent Application Laid-Open No. 53-62059.) ``Problems to be Solved by the Invention'' However, in such a conventional window glass lifting device, there is only one guide rail.
The window glass gets caught or gets twisted while being raised and lowered, making it difficult to raise and lower smoothly, and the support rigidity tends to be insufficient, requiring a stabilizer to prevent the window glass from swinging, making the structure complex. On the other hand, there was a problem in that the number of man-hours required for assembly increased, resulting in increased costs.

The present invention has been made in view of these conventional problems, and is a window glass lifting device that solves the above problems by being able to support window glass with high rigidity with a simple configuration. is intended to provide.

``Means for Solving the Problems'' The gist of the present invention for achieving the above object is to provide a means for moving the upper and lower sides of a pair of mutually parallel guide rails arranged along the vertical locus of the window glass. are consolidated and formed into a frame shape as a whole,
A drive cable is routed so as to have a portion along at least one guide rail, and a carrier plate fixed to the window glass is slidably fitted to both guide rails, and the drive cable is connected to at least one guide rail. The guide rail is fixed to the rear plate and moved vertically to be driven up and down, and the guide rail is groove-shaped and has a constant cross section with curled portions formed at the tips of both side wall portions. It consists in a device for lifting and lowering window glass.

``Function'' The window glass is guided by two frame-shaped and highly rigid guide rails, and the guide rails have a grooved cross section, and a curled part is formed at the tip of the grooved side wall. Therefore, the guide rail itself has high rigidity and is easy to form, and the window glass lifting and lowering device has high support rigidity for the window glass and operates smoothly.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 to 3 show an embodiment of the present invention.

As shown in FIG. 3, the elevating device 10 includes upper and lower connecting members 11, in which upper and lower portions of a pair of guide rails 20, 20a, which are parallel to each other along the elevating locus of the window glass A, are fixed to each other. 11 to form a unit-shaped frame member 12, and various members are attached to the frame member 12 as a base.

As can be seen in FIG. 2, the upper and lower connecting members 11,
Attachment nuts 13, 13, . . . are fixedly installed in 11. Upper and lower guide pulleys 14, 14 are attached to the connecting members 11, 11 near one of the guide rails 20, and cables 15, 15a are routed around the upper and lower guide pulleys 14, 14. The cables 15, 15a between them run along the guide rail 20. Cable 15, 15a
One end of each extends to the manual drive section 16, and is wound around and fixed to the drive pulley 16a.

Carrier plates 30, 30a fixed to the window glass A are slidably fitted into the guide rails 20, 20a. The carrier plate 30 connects the cables 15, 1 to its cable connections 31, 32.
The other end of the cable 5a is fixed and is driven in conjunction with the movement of the cables 15, 15a by rotation of the drive pulley 16a.

As shown in FIG. 1, the guide rail 20 has a groove shape with side walls 22 extending from both sides of a bottom 21, and a curled portion 23 that projects outward is formed at the tip of the side wall 22. formed into a constant cross section,
As a whole, it has a curved shape that follows the upward and downward locus of the window glass A. The guide rail 20 can be manufactured by roll forming. Further, the guide rail 20a is also formed in a similar shape.

The carrier plates 30, 30a are window glass A.
The main bodies of the carrier plates 30, 30a have a groove-shaped cross section that embraces the opening side of the guide rail 20 including the curled portion 23. That is, side wall portions 33, 33 extend from both sides of the bottom portion 32 having a groove-shaped cross section, and a flange 34 that bends inward is provided at the end of the side wall portions 33, 33. Consolidation piece 31
is fixed to the bottom part 32.

The carrier plate 30 holds the guide rail 20, and is slidably and irremovably fitted through a slider 40 formed of a material such as synthetic resin.

Next, the effect will be explained.

When the drive pulley 16a of the manual drive unit 16 is driven to rotate, the cables 15, 15a are moved vertically, and the carrier plate 30 connected to the cables 15, 15a is raised and lowered while being guided by the guide rail 20 and fixed thereto. Window glass A is raised and lowered to open and close. Also, at that time, the carrier plate 3
Similarly, the guide rail 20a guides the guide rail 20a to move up and down.

The guide rail 20 has a groove-shaped cross section and is also provided with a curled section 23, so it has a large section modulus, and the frame member 12 of which the guide rail 20 is constructed supports each section, making it easy to carry. The rear plate 30 and other parts do not wobble and operate smoothly.

Incidentally, for assembly, it is sufficient to treat the whole as a unit and simply screw the mounting bolts into the nuts 13, 13.

FIG. 4 shows another embodiment, in which a mounting plate 17 is installed approximately between the center portions of the guide rails 20, 20a, a power drive section 18 equipped with a motor 18a is attached to the mounting plate 17, and the power drive unit 18 is mounted on the mounting plate 17. drive pulley 19
The cable 15 is wrapped around the cable 15 and then solidified.

"Effects of the Invention" According to the window glass elevating device according to the present invention, the guide rail has a highly rigid cross section, and the window glass is supported and raised and lowered by a frame member having a pair of guide rails as a component. Therefore, the support rigidity of the window glass is extremely high, and the window glass not only moves up and down smoothly, but also has a simple structure and is easy to handle, reducing assembly man-hours and reducing overall costs. .
