Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to an elevating device for a window guide that elevates and opens a window glass by a drive cable, and is used for a window of a sashless door of an automobile, for example.

"Prior Art" As a conventional window glass lifting device, there is, for example, one shown in Figs.

That is, the elevating device 1 forms a frame-shaped base member 4 by fixing the upper and lower parts of a pair of guide rails 2 and 2 arranged side by side along the ascending and descending path of the window glass by the upper and lower connecting plates 3 and 3, respectively. I am doing it.

The drive cable 7 is bridged between the guide pulleys 5 and 5 mounted on the connection plates 3 and 3 and the drive unit 6, and the drive cable 7 is fixed to the drive carrier 8 fitted to one guide rail 2 so as to be vertically movable. It is shown that a floating carrier 9 is fitted to the other guide rail 2 so as to be movable up and down, and a window glass is fixed to the drive carrier 8 and the floating carrier 9.

[Problems to be solved by the invention] However, in such a conventional window glass lifting device, the position of the drive carrier 8 for fixing the upper and lower guide pulleys 5 and 5 and the drive cable 7 is fixed, and is changed. Therefore, it is not possible to apply it to those with different window glass positions, center of gravity, etc. due to differences in specifications, vehicle types, etc., and a lifting device must be set as a separate component for each of those differences. However, since parts cannot be shared, there is a problem that various parts are generated, which hinders rationalization and prevents cost reduction.

The present invention has been made by paying attention to such conventional problems, and it is possible to easily cope with differences in specifications, differences in vehicle types, etc. It is an object of the present invention to provide a solved window glass lifting device.

[Means for Solving Problems] The gist of the present invention for achieving such an object is to provide a window glass lifting device for slidably supporting the window glass along the path of the window glass lifting. A frame-shaped base member is formed by firmly fixing upper and lower members of a pair of guide rails arranged side by side with upper and lower connecting plates, respectively, and providing a carrier for fixing the window glass across the pair of guide rails. Both ends of the carrier are vertically movably fitted to both guide rails, guide pulleys are attached to the upper and lower connecting plates, respectively, and a drive cable is hung between the guide pulleys along the guide rails and driven. The drive cable is connected to a portion, the carrier is provided with a plurality of cable connection portions distributed between the guide rails, and the drive cable is selectively attached to the connection portion. It consists in lifting device of the glazing, characterized in that the table allows consolidation.

"Operation" Since the carrier, which is fitted to both guide rails so that both ends can be moved up and down, is provided with multiple cable connection parts distributed between both guide rails, the center of gravity and shape of the window glass may differ due to differences in specifications. If they are different, it is possible to select a cable connecting portion at a position suitable for that and to fix the drive cable to the carrier at that position so that the window glass can be smoothly moved up and down to open and close.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the present invention.

As shown in FIGS. 1 and 4, the elevating device 10 is mounted on the door A to elevate the window glass B.

The elevating device 10 includes curved guide rails 30 and 30 arranged in parallel in a front-rear pair along the elevating direction of the window glass B on the door A, which is a mounting site, and both guide rails 30 ,.
A frame-shaped flat base member 20 as a whole is formed by the connecting plates 21 and 21 that fasten the upper end portion and the lower end portion of 30 together.

The guide plate 1 is attached to the upper and lower connecting plates 21 and 21.
2, 13 are pivotally mounted via pivots 12a, 13a, and pulley mounting holes 22, for fixing the pivots 12a, 13a,
Plural holes 22 and 23, 23 are formed in each connecting plate 21. The drive cable 11 having an operation section parallel to the one guide rail 30 has guide pulleys 12, 13
Have been routed to.

The drive cable 11 is wound around the guide pulley 12 at the upper portion and is wound around the guide pulley 13 at the lower portion, inserted into the outer tubes 14 and 15 having flexibility, and extends to the drive portion 40. Is looped over as a whole.

The upper and lower connecting plates 21 have outer tubes 14, 1
The outer tube fitting grooves 24, 24, 25, 25 of the end members 14a, 15a provided at the base end of 5 are engraved on both sides.

Further, each of the connecting plates 21 and 21 has a mounting surface 26 to the inner panel of the door A.
Weld nuts 27, 27 with which mounting bolts are screwed to 6 are welded.

The drive unit 40 has a drive pulley housed in a housing 41, and has a motor 42 for rotating the drive pulley or a manual rotation shaft (not shown). The ends of the outer tubes 14 and 15 are connected to one end of the housing 41,
The end portion of the drive cable 11 is wound around the drive pulley and fixed.

A carrier 50 is provided which straddles between the guide rails 30 and 30 and in which the window glass B is fixed. Both ends 51, 52 of the carrier 50 are fitted to both guide rails 30, 30 via a roller unit (not shown) so as to be movable up and down.

A plurality of cable connecting portions 5 are provided in the middle of the carrier 50.
3,53. ． ． Is provided.

As shown in FIGS. 2 and 3, the cable connecting portion 53.
Is formed by cutting and raising pieces 53b, 53b at both ends of the rectangular hole 53a, and a connecting member 54 is fitted therein.

The connecting member 54 is composed of an enlarged head 55 that cannot pass through the rectangular hole 53a and an insertion portion 56, and connecting grooves 57 and 57 are formed vertically from the enlarged head 55 to the insertion portion 56. The connecting groove 57 is composed of a locking groove 57a that allows the end fitting 11a of the drive cable 11 to pass therethrough, and an insertion groove 57b that allows only the main body of the drive cable 11 to pass through.

Next, the operation will be described.

In the drive unit 40, when the drive pulley is rotated by the motor 42 or the manual handle, one side of the drive cable 11 is rolled in, and the other side is paid out and moved in the axial direction thereof, so that it is connected to the drive cable 11. Carrier 5
0 also goes up and down, and the window glass B is opened and closed.

When the position of the cable connecting portion 53 for connecting the drive cable 11 to the carrier 50 is not appropriate due to the difference in specifications and the center of gravity of the window glass B is deviated, as shown in the phantom line in FIG. Cable connection part 53 at the right end
Is used to mount the connecting member 54, and accordingly, the guide pulleys 12 and 13 are attached to the end pulley mounting holes 22 and 23, for example.
Attach to.

The connecting member 54 inserts the inserting portion 56 into the cable connecting portion 53, presses the expanding head 55 against the surface of the carrier 50, and then crimps the cut-and-raised piece 53b so as to press the expanding head 55. The drive cable 11 passes through the end fitting 11a from the end of the connecting groove 57 on the side of the expansion head 55 into the locking groove 57a, the main body of the drive cable 11 passes through the insertion groove 57b, and is moved to the insertion portion 56 to be tensioned. , 13

As shown in FIGS. 6 and 7, the drive parts 40 are pulled out in the opposite directions, and the fitting grooves 24, 24, 25, of the end members 14a, 15a at the base ends of the outer tubes 14, 15 are formed.
25 can also be used by converting it to the opposite side.
The drive unit 40 is provided with a drive pulley 43 on the back side of the housing 41.

[Advantages of the Invention] The window glass lifting device according to the present invention makes it possible to easily change the connection position of the drive cable to the carrier. A lifting device can be used to improve productivity, reduce costs, and prevent common sharing, so use a lifting device that lifts the window glass smoothly and reliably. You can
