Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a window glass elevating device that opens and closes by sliding up and down at a mounting portion, and is used for automobile windows.

"Prior Art" As a conventional window glass lifting device, there is one disclosed in, for example, Japanese Utility Model Publication No. 57-4697.

That is, the publication discloses a device in which guide rails are arranged in parallel in front and behind a door, which is an attachment part, and a glass holder, which is a carrier plate, is slidably guided on the guide rails via rollers. . Generally, grease is interposed between the roller and the guide rail.

``Problem that the invention aims to solve'' However, since such conventional window glass lifting devices do not have a grease reservoir, the grease must exist in the gap between the roller and the guide rail. First, since there is no part to hold the grease, there are problems in that the grease is unevenly distributed and cannot be used for lubrication, or that too much grease drips and travels along the rails, contaminating the window glass and door panels. .

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 providing a means for retaining grease to prevent grease from flowing or being unevenly distributed. It is intended to.

``Means for Solving the Problems'' The gist of the present invention for achieving the above purpose is to provide a windowpane lifting device that is slidably supported on a mounting part and that follows the lifting locus of the windowpane. A guide rail is provided, a carrier plate fixed to the lower end of the window glass is fitted onto the guide rail via a slider, and the guide surface of the guide rail in contact with the slider is provided with a carrier plate fixed to the lower end of the window glass. A window glass lifting device is characterized in that a recessed portion for a grease reservoir is formed along a movement trajectory of a child.

"Function" Grease is retained in the groove for a grease reservoir along the movement trajectory of the slider, and as the slider moves, grease is replenished between the slider and the guide rail. This prevents the grease from flowing down.

"Embodiment" Hereinafter, an embodiment of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, the lifting device 1
0 is attached to the door A and is used to raise and lower the window glass A1.

The elevating device 10 includes a frame-shaped base member 20, a pair of guide rails 30, 30, and both guide rails 30, which are arranged parallel to each other as a pair of front and rear guide rails along the elevating direction of the window glass A1 on the door A, which is an attachment portion. A connecting bracket 40 that connects the upper and lower parts of 30, respectively.
A cable 11 having an operating section parallel to one guide rail 30 is stretched across the upper and lower guide pulleys 12, 12 and the drive section 13.

The upper or lower portions of the guide rails 30, 30 are welded and fixed to a flange 41 erected around the connection bracket 40 except for a part thereof.

The drive unit 13 installed on the support plate 22 connecting the intermediate portions of the guide rails 30, 30 includes a drive pulley 13a and a drive motor 13b.

As can be seen in FIGS. 1 and 3, the guide rails 30, 30 are channel-shaped and have similar cross-sectional shapes, with a groove 32 having a substantially V-shaped cross section formed in one side wall 31, and a groove 32 having a substantially V-shaped cross section formed in the other side wall 31. The side wall 33 is formed into a planar shape.

Furthermore, as can be seen in FIGS. 1 and 3 to 6, carrier plates 60, 60a are connected to both guide rails 30, 60a through roller units 50, respectively.
30 so that it can roll.

The roller unit 50 has a carrier plate 6
0, 60a and is a part thereof, and is connected to the cable 11, the upper and lower ends of the roller support portion 61 of the carrier plate 60 have a convex outer periphery. roller 5
1 and 51 are pivotally supported via pivots 52 and 52, and a pressure roller 53 whose outer periphery center portion is substantially flat is mounted between the rollers 51 and 51. The axis of each roller faces in the opening direction of the opening groove of the guide rail 30. The roller 51 and the pressure roller 53 are movable elements that are fitted into the guide rail 30 so as to be movable up and down.

The outer peripheries of the rollers 51, 51 are in rolling and sliding contact with the groove 32 of the side wall 31 of the guide rail 30, and the pressure roller 53 is in rolling and sliding contact with the side wall 33.

As shown in FIGS. 5 to 7, the pressure roller 5
A pressure roller 5 is attached to the side wall 33 on which the roller 3 rolls and comes into sliding contact.
A grease reservoir recess 34 is formed along the movement locus 3. The grease reservoir recess 34 is divided into several parts along the entire length of the guide rail 30, and is filled with grease B.

The base end of a sliding lever 55 is pivotally attached to the roller support portion 61 of the carrier plate 60 via a pivot 56, and the pressure roller 53 is attached to the base end of the sliding lever 55 with a slight angle relative to the pivot 56. Eccentric shaft 5
It is pivoted via 7.

The sliding lever 55 is biased clockwise in FIG. 4 by a spring 58 stretched between it and the carrier plate 60, and the pressure roller 53 is pressed against the side wall 33. As a result, the roller unit 50
is slidably fitted to the guide rail 30.

The carrier plate 60 has a support piece part 62 that supports the roller support part 61 and extends along the window glass A1.
and a cable connection piece portion 63 extending on the opposite side.

The end portion 11a of the cable 11 extending downward from above and the end portion 11b of the cable 11 extending from below are connected to the cable connecting piece portion 63, respectively.

The other carrier plate 60a is similarly equipped with a roller unit 50 that fits into the guide rail 30, and the carrier plate 60a is also provided with a support piece 62a along the window glass A1. It is freely movable with respect to the guide rail 30.

In order to assemble the window glass lifting device 10 having the above-mentioned configuration, since the lifting device 10 is made into a unit as a whole based on the base member 20,
Bring the whole thing into door A, and attach each mounting surface 43, 43.
By screwing the mounting bolts 21 into the weld nuts 44, 44, . . . of the weld nuts 44, 43b, the overall position is almost determined, and assembly is extremely easy except for slight adjustments.

When the drive motor 13b of the drive unit 13 is operated, the drive pulley 13a rotates and the cable 11 is moved vertically, so that the carrier plate 60 connected to the cable 11 is also moved up and down. As a result, window glass A
1 is raised and lowered and opened and closed.

When the window glass A1 is raised/lowered and opened/closed, the roller units 50, 5 fitted to the guide rails 30, 30
0 is guided up and down, but since the pressure roller 53 is pressed against the side wall 33 by the elastic force of the spring 58, the roller 51 and the pressure roller 53
The rollers 51 fit into the grooves 32 and come into pressure contact with the side wall 31, and the pressure roller 53 comes into pressure contact with the side wall 33.

A pivot shaft 56 and an eccentric shaft 5 that pivot the swing lever 55
The biasing force of the spring 58 is increased by the lever action caused by the deviation from the groove 7, and the pressure roller 53 is strongly pressed against the side wall 33, so there is an error in the direction in which the groove 32 separates from the side wall 33. Also, due to the biasing force of the spring 58, the roller units 50, 50 move the rollers 51,
It is fitted to the guide rails 30, 30 through the pressure roller 53 without wobbling.

The groove 32 is provided on one side wall 31, and the other side wall 33 has no groove and is flat, so even if the groove 32 is parallel to the side wall 33 and has an error, the flat roller 53 will not move the side wall 33. There is no problem as long as the guide rails 30, 30 move only on the surface of the guide rails 30, and this is a relief for achieving dimensional accuracy of the guide rails 30, 30 themselves.

Then, while the pressure roller 53 moves, the grease B filled in the grease reservoir recess 34 adheres to the outer periphery of the pressure roller 53, thereby smoothing the movement of the pressure roller 53. Since a considerable amount of grease B can be stored in the grease reservoir recess 34, the pressure contact roller 5 can be stored without running out for a long period of time.
Grease can be supplied to 3.

In this embodiment, since the lifting device 10 is made into a unit by the base member 20, assembly is easy, and since the grease reservoir recess 34 is provided separately,
Grease B has the advantage that it is difficult to spill at any time.

"Effects of the invention" According to the window glass lifting device according to the invention, the guide rail is provided with a grease reservoir recess, and the rollers can be sufficiently supplied with grease, and the roller can be refilled with a considerable amount of grease. Therefore, smooth operation of the lifting device can be ensured without contaminating window glass or doors.
