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 at a mounting portion, and is used for automobile windows.

"Conventional technology" Conventional window glass lifting devices include, for example,
There is one disclosed in Japanese Utility Model Application Publication No. 58-68574.

That is, the publication discloses a window opening/closing device in which a slider, which is a carrier plate attached to a window glass, is slidable in the opening/closing direction along a guide rail provided on a fixed side, which is an attachment part.

``Problems to be Solved by the Invention'' However, since the conventional window glass opening/closing device has only one slider, which is a carrier plate, the load tends to be biased when the window glass is raised and lowered, causing the problem of prying. This has led to problems such as a jitter phenomenon, vertical and longitudinal rattles, a lack of smooth opening/closing of window glass, and passenger discomfort during operation.

The present invention has been made by focusing on these conventional problems, and provides a window that can apply driving force evenly to the window glass to solve the above problems, and also improve assembly workability. The purpose is to provide glass lifting equipment.

``Means for Solving the Problems'' The gist of the present invention for achieving the above object is to provide a window glass lifting device that opens and closes by sliding up and down at the mounting part, in which the lifting locus of the window glass is A frame-shaped base member is formed by a pair of guide rails arranged in parallel along both guide rails, and an upper and lower connecting bracket that connects the upper and lower ends of both guide rails, respectively. The drive cable is routed so that it has a portion that moves in the same direction, and a carrier plate to which the lower part of the window glass is fixed is fitted to each of both guide rails so as to be movable up and down, and both carrier plates are connected to the drive cable. A window glass lifting device is characterized in that it is fixed to a cable.

``Operation'' The carrier plate connected to the cable is driven up and down along each of the pair of guide rails, and the operating load is applied evenly to both sides of the lower part of the window glass, and the load is stabilized without being biased. The window glass is raised and lowered.

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

The figure shows an embodiment of the invention.

As shown in FIGS. 1 to 3, a lifting device 10 is attached to a door A and is used to raise and lower a window glass A1.

The elevating device 10 connects the upper and lower portions of both guide rails 30, 30, respectively, to a door A, which is an attachment portion, and guide rails 30, 30, which are arranged in a pair of front and rear parallel to each other along the lifting direction of the window glass A1. A frame-shaped base member 20 is formed by the connecting brackets 40, 40.

Carrier plates 60, 6 are connected to the guide rails 30, 30 via roller units 50, respectively.
0a is slidably fitted.

The cable 11 to which the carrier plates 60, 60a are connected has a portion 12 along one guide rail 30 and a portion 13 along the other guide rail 30.
The base member 20 is wound around guide pulleys 11a, 11b and guide pulleys 11c, 11d disposed above and below the base member 20 so as to have a
They are arranged in a figure-eight shape as a whole so that they intersect at approximately the center. Site 12 and site 13 move in the same direction.

One of the crossing portions of the cable 11 is guided through a guide tube 14 whose both ends are secured to upper and lower connection brackets 40, 40.

The connecting brackets 40, 40 basically have the same shape, and can be used for the upper and lower parts by rotating 180 degrees in a plane. rail 3
The upper or lower part of 0 is fixed by welding.

A pulley support surface 42 and a mounting surface 43 are formed in a stepped manner at both ends of the connection bracket 40, the guide pulleys 11a to 11d are supported on the pulley support surface 42, and the mounting bolt 21 is screwed into the mounting surface 43. Weld nuts 44 are welded, and the base member 20 has mounting surfaces 43 provided at two locations on the top and two locations on the bottom.
It is fixed to door A.

A drive unit 15 is installed on the support plate 22 that connects the intermediate portions of the guide rails 30, 30.
The drive unit 15 includes a drive pulley 15a and a drive motor 1.
5b, and the other of the crossing portions of the cables 11 is wound around the drive pulley 15a.

As can be seen in FIGS. 1 and 4, the guide rails 30, 30 are channel-shaped, and one side wall 3
1 is formed with a groove 32 having a substantially V-shaped cross section, and the other side wall 33 is formed in a planar shape.

As can be seen from FIGS. 4 to 6, the roller unit 50 is equipped with carrier plates 60, 60a fixed to the window glass A1 having the same structure, and one carrier plate 6
0, a roller 5 having a convex outer periphery is attached to the upper and lower ends of the roller support portion 61 of the carrier plate 60.
1 and 51 are pivotally supported via pivots 52 and 52, and a flat roller 53 is installed between the rollers 51 and 51.

The outer periphery of the rollers 51, 51 is in sliding contact with the groove 32 of the side wall 31 of the guide rail 30 so as to be able to roll.

The flat roller 53 is in rolling and sliding contact with the side surface 33, and the base end of the swing lever 55 is pivoted between the roller support portion 61 of the carrier plate 60 and the stop plate 54 via the pivot shaft 56. and the flat roller 53
is pivotally supported at the base end of the swing lever 55 via an eccentric shaft 57 that is slightly eccentric with respect to the pivot shaft 56 .

The swing lever 55 is biased clockwise in FIG. 6 by a spring 58 stretched between it and the carrier plate 60, and the flat 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 other carrier plate 60a is similarly equipped with a roller unit 50.

The carrier plates 60 and 60a have the same structure including the roller unit 50 of the same structure.If the carrier plate 60 is explained as a representative, the carrier plate 60 has a roller support part 6.
1 to both sides along the window glass A1.
and a cable connecting piece 63 extend.

Long grooves 63, 63b are formed in the cable connecting piece 63 in the moving direction of the carrier plate 60, and the sliding pieces 64, 64 connect the cable via the pin 64a and sliding end 64b that engage with the long grooves 63a, 63b. It is slidably supported by the upper and lower parts of the connecting piece 63, and a spring 65 is tensioned between the sliding pieces 64 and 64 to urge them to approach each other. Since the carrier plate 60a has the same configuration, similar parts appearing in the drawings are designated by the same reference numerals, and redundant explanation will be omitted.

If the carrier plate 60 is the carrier plate 60, the carrier plates 60, 60a have upper and lower sliding pieces 64, 64.
, an end 12a extending from the top of the portion 12 of the cable 11 and an end 12b extending from the bottom.
are connected via trunnion pins 12c, 12c, respectively, and if it is a carrier plate 60a, the upper and lower sliding pieces 64, 64 have an end 13a from the top of the portion 13 of the cable 11 and a lower end 13a. The end portion 13b extending from the trunnion pin 13
c and 13c, respectively.

Lifting device 10 for window glass A1 having the above structure
To assemble the lifting device 10, the base member 20
Since it is made into a unit based on the above, by bringing the entire unit into the door A and screwing the mounting bolts 21 into the weld nuts 44 of each mounting surface 43, the position of the entire unit is almost determined, and subtle changes can be made. It is extremely easy to assemble, except for adjustments.

When the drive motor 15b of the drive unit 15 is operated, the drive pulley 15a rotates, and the cable 11 is moved vertically.

When the cable 11 moves vertically, its portion 12
Since the parts 13 move up and down in the same moving direction and speed, the carrier plates 60, 60a connected to the cable 11 also move up and down in the same moving direction and speed.

As a result, the window glass A1 is raised and lowered by applying driving force to two locations at the bottom, and is smoothly raised and lowered and opened and closed without biasing the driving load. The sliding piece 64 moves relatively under the tension of the spring to absorb the slack in the cable 11 that occurs when the cable 11 is moved up and down.

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 flat roller 53 is pressed against the side wall 33 by the elastic force of the spring 58, the roller 51 and the flat roller 53
The rollers 51 fit into the grooves 32 and press against the side walls 31, and the flat rollers 53 press against the side walls 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 spring 7, and the flat roller 53 is strongly pressed against the side wall 33, so there is an error in the direction in which the flat roller 53 separates from the side wall 33. Also, due to the biasing force of the spring 58, the roller unit 50 moves the roller 51,
It fits onto the guide rail 30 via the flat 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.
Even if there is an error in the direction parallel to the side wall 33 of the guide rail 30, there is no problem as the flat roller 53 simply moves on the surface of the side wall 33, and this is a relief in achieving dimensional accuracy of the guide rail 30 itself. .

"Effects of the Invention" According to the window glass elevating device according to the present invention, the carrier plate, which is driven up and down along a pair of parallel guide rails, is fitted in two locations at the lower end of the window glass. Because the driving force is applied to the window glass to raise and lower it, the operating force is applied evenly to the window glass without being biased, and the window is raised and lowered smoothly, without rattling or jerking, making it smooth and comfortable to operate. It can be a window glass lifting device. In addition, since the lifting device is integrated into a unit based on the base member, the cables are routed onto the base member before the lifting device is installed inside the door, making the work extremely efficient. It can be done.
