Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an elevating guide device for an automobile door glass.

2. Description of the Related Art Generally, as shown in FIG. 7, a door glass 1 of an automobile is constructed so that it can be moved up and down by a window regulator 2, and the window regulator 2 is usually provided with a lifting guide device.

Conventionally, this elevating guide device has a guide rail 4 having a substantially C-shaped cross section in the longitudinal direction of the door inner panel 3 as shown in FIG.
And the slide rail 7 is slidably received by the guide rail 4 mounted on the shaft end of the link bar 6 protruding from the glass holder 5. As the sliding contact piece 7, a substantially quadrilateral outer ring portion 7a and an inner ring portion 7b serving as a central boss portion as shown in FIG. 9 are spoke portions 7c, 7c. Connect the outer ring 7
As shown in FIGS. 10 and 11, a is formed to be slightly smaller than the inner lateral width of the guide rail 4 and is fitted into the C-shape of the guide rail 4 so as to be slidably supported through a lubricant such as grease. Things are assembled. Instead of this, a circular outer ring portion 7a 'is also used as shown in FIG.

Problems to be Solved by the Invention By the way, the guide rails 4 to be assembled to this lifting guide device
Is not a straight line, but is formed to be slightly bent in the thickness direction of the door as shown in FIG. 13a. The bending is performed by roll-forming the entire body into a substantially C-shaped cross section and then supporting it from the C-shaped portion with a core material and bending the axial direction forward or backward. As a result, as shown in FIGS. 13B and 13C, the cross-sectional shape of the bent portion may become slightly wider or narrower.

When the sliding contact piece 7 described above is fitted into the guide rail 4, when the cross-sectional shape of the bent portion is widened, as shown in FIG. 14, it is between the outer ring portion 7a and the inner surface of the guide rail 4. Since a gap is generated in the door glass, the door glass rattles as the door glass moves up and down, and a vibration noise is generated. If the bent portion has a narrow cross-sectional shape, the spokes 7c, 7
Since the outer ring portion 7a of the sliding contact piece 7 is temporarily caught by the protrusion of c, the door glass cannot be smoothly moved up and down at a constant speed.

Means for Solving the Problems In an elevator door glass raising / lowering guide device according to the present invention, an outer ring portion and an inner ring portion that bears a link bar are provided as a sliding contact piece that abuts and abuts the inner surface of the guide rail. At least in the width direction of the cross-section of the guide rail, are connected by a connecting portion so that a space is created between the outer ring portion and the inner ring portion, and the left and right sides of the outer ring portion are flexibly deformable. Is assembled.

Action In this elevating guide device, the outer ring of the sliding contact piece that projects and abuts the inner surface of the guide rail is formed so that a space is created between the outer ring portion and the inner ring portion at least in the width direction of the cross section of the guide rail. Since it is connected to the inner ring part and is bent and deformable on the left and right sides, even if the guide rail is partially widened or narrowed, the sliding contact piece elastically deforms and the door glass moves up and down. There is no possibility of backlash or temporary catch on the guide rail.

Example The following is a description with reference to FIGS. 1 to 6.

This door glass lift guide device is equipped with a window regulator that is connected to a glass holder attached to the door glass to move the door glass up and down, as shown in Figs. 7 and 8. The one end side of the link bar is pivotally supported, and the other end of the link bar is supported by a spherical joint portion on a sliding contact piece, and the sliding contact piece is fitted and retained in a guide rail 1 fixed to a door panel via a bracket. It is configured by Further, in this elevating guide device, the link bar is supported by a spring so that the sliding contact piece can be pressed against the guide rail even if the distance between the guide rail and the glass holder changes, and the glass is used to regulate the swing of the link bar. The holder is equipped with a stopper.

The guide rail is formed by bending the axial line at an appropriate position in the thickness direction of the door, and is formed by bending a metal plate material so as to have a substantially C-shaped cross section.

The sliding contact pieces 10 and 20 made of an elastic material such as polyacetal resin are used, and the sliding contact piece 10 shown in FIG. 1 has a substantially quadrilateral outer ring portion 11 and an inner ring which is supported by the above-mentioned link bar. It is formed by connecting the ring portion 12 with spoke-like connecting portions 13, 13 ... Which are projected in four diagonal directions so as to have a space in the left-right direction. As shown in FIGS. 2 and 3, the outer ring portion 11 is formed to be slightly larger than the inner lateral width so that the left and right side edges 11a and 11b project and contact the inner side surface of the guide rail 30. 11a and 11b are preferably formed in a substantially arcuate shape so as to reduce frictional resistance with the guide rail 30.

Instead of this, as in the sliding contact piece 20 shown in FIG.
Can also be formed in a circular shape. Even the sliding contact piece 20 is 5th
As shown in the figure, the outer diameter of the guide rail is slightly larger than the inner width of the guide rail whose lateral cross-sectional shape is slightly wider so that the left and right side edges 21a and 21b are projected against and abut against the guide rail 30. Also, this sliding contact piece 20 also connects the outer ring portion 21 and the inner ring portion 22 by the spoke-shaped connecting portions 23, 23 ... Which project in diagonally four directions, and the outer ring portion 21 has the connecting portions 23, 23. It is advisable to integrally form the anti-rotation projections 24, 24 ...

In the door glass elevating / lowering guide device constructed by assembling these sliding contact pieces 10, 20, even if the axis of the guide rail 30 is partially widened or narrowed as shown in FIG.
The sliding contact piece 10, 10 and 20 are formed of an elastic material, and further, the left and right side edges 11a, 11b, 21a, 21b of the outer ring portions 11 and 21 can be flexibly deformed to follow the different widths of the guide rail 30. 20 can be smoothly slid inside the guide rail 30.

Effects of the Invention As described above, according to the vehicle door glass lifting guide device of the present invention, the sliding piece can be smoothly slid on the guide rails, so that the door glass can be stably moved up and down. It is a thing.
