Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a window glass lifting device that moves the window glass of an automobile door up and down to open and close it. This invention relates to improvements to cable-type devices that move up and down.

(Prior Art) Conventionally, as this type of window glass lifting device, as disclosed in, for example, Japanese Utility Model Application Publication No. 57-88866, a sector gear that meshes with a pinion that is pivotally supported on a door panel is fixed to the lower end. A main arm whose upper end is slidably connected to a glass holder attached to the lower end of the window glass, a main arm which is swingably connected to the main arm, whose lower end is slidably connected to the door panel, and whose upper end is slidably connected to the glass holder. The main arm and the auxiliary arm are linked by the rotation of a pinion, and the windshield is moved up and down. The X-link type is well known and is widely used in actual vehicles.

However, since this X-link type uses a link mechanism, it can slide the window glass and has the advantage of being highly rigid, but on the other hand, the link mechanism occupies a large space inside the door panel. The structure is complicated and the weight increases,
Moreover, since it is a link mechanism, there is a drawback that the operating force varies depending on the up/down position of the window glass.

On the other hand, as a window glass lifting device other than the X-link type, there is a cable type. In other words, this cable type has a cable member (wire member) that is stretched almost vertically within the door panel and is connected to the lower end of the window glass via a connecting member, and a guide rail member that guides the window glass up and down. This device opens and closes the window glass by moving the cable member up and down, and has excellent advantages such as being lightweight, occupying only a small space in the door panel, and having no fluctuation in operating force. There is.

(Problem to be solved by the invention) By the way, when the windshield of the front door of a car is moved downward and stored inside the door panel, it is necessary to avoid interference with the door lock device disposed at the rear end of the door panel. First, the window glass is lowered while tilting forward, and then lowered while standing up to its original state in order to avoid collision of the front edge of the glass with the front wall of the door panel due to the lowering of the window glass in the forward tilted state. need to be moved to. Additionally, when lowering the rear door window glass, it is necessary to lower the window glass while tilting it forward to avoid interference with the tire house notch formed at the rear end of the door. These demands on the movement of the windshield are particularly noticeable in hard-top type automobiles, which have no window sash and have a large window glass area.

However, the above-mentioned cable type window glass lifting device has a problem in that the holding rigidity for the window glass is low and it is difficult to move the glass up and down while tilting the glass, so that the above movement of the window glass cannot be realized.

The present invention provides the above-mentioned cable-type window glass lifting device in which the guide rail member for guiding the lifting and lowering movement of the window glass is formed into a predetermined bent shape, and is rotated at a predetermined distance substantially in the vertical direction around the window glass. By fitting a plurality of freely movably mounted roller members into the above-mentioned bent guide rail member, a lightweight and compact cable-type windshield lifting device can be used to move the windshield to a door lock device or tire house. The main purpose is to allow the door panel to be stored in the door panel while being tilted to avoid cutouts and the like.

However, in that case, in order to restrict the displacement of the window glass in the door inward and outward directions (vehicle width direction), two pairs of stabilizers that slide against the window glass are installed at the front and rear of the belt line portion of the upper edge of the inside of the door panel. When the window glass is supported by a guide rail member, the strength of the guide rail member that restricts the displacement of the lower part of the window glass in the door-outside direction is insufficient, and it is necessary to improve its stability. .

Therefore, a further object of the present invention is to increase the strength of the bent guide rail member by integrating it with a component of a drive device that moves the window glass up and down. The goal is to ensure that regulations can be implemented stably.

(Means for solving the problem) In order to achieve the above object, the solving means of the present invention includes a cable guide groove for storing a cable member stretched vertically in a door panel of an automobile door, and a predetermined A guide member having a roller guide groove formed in a bent shape is disposed substantially vertically within the door panel, and the cable member in the cable guide groove is connected to the lower end of the window glass by a connecting member. Furthermore, by rotatably attaching a plurality of roller members to the lower part of the window glass at a predetermined distance in the vertical direction, and at the same time fitting the roller members rotatably into the roller guide groove of the guide member, the cable member The window glass is configured to be rotatably opened and closed by vertical movement of the windshield.

(Function) With the above configuration, in the present invention, when the window is opened and closed, the cable member housed in the cable guide groove of the guide member moves up and down, and the window glass connected to the cable member moves up and down. As the glass moves up and down, a plurality of roller members attached to its lower part roll within the roller guide groove of the guide member, and the window glass is held on the door panel by the guiding action of the roller member by the roller guide groove. Go up and down while being moved. At this time, since the roller guide groove is integrated with the cable guide groove to form a guide member, its strength is greatly increased, and the roller guide groove receives the force acting from the lower part of the window glass in the direction inside and outside of the door. displacement can be reliably regulated.

(First Embodiment) Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

In FIGS. 1 to 6, 1 is a door panel of an automobile front door, and the door panel 1 is formed by integrally joining an inner panel 2 and an outer panel 3, and the upper edge of the door panel 1 has inner and outer surfaces. A communicating opening 4 is formed, and a window glass 5 is moved up and down through the opening 4 to open and close the window.

Inside the door panel 1, a guide member 6 extending substantially in the vertical direction is attached to the inner surface of the inner panel 2 at a substantially central portion in the front-rear direction. The guide member 6 includes a cable guide groove 7 having a substantially U-shaped cross section, and a roller guide groove 8 integrally joined to the rear edge of the cable guide groove 7.
Pulleys 9, 9 are pivotally supported at the upper and lower ends of the inner surface of the cable guide groove 7, and an intermediate portion of a cable member 10 (wire member) is stretched substantially vertically between the pulleys 9, 9. Cable member 1
0 is housed in the cable guide groove 7.
Further, two pairs of bolts 11 and 1 are attached to the lower end of the window glass 5 in the middle part of the cable member 10.
1 and a plate-shaped connecting member 13 attached via nuts 12, 12, and the cable member 10 is connected to the lower end of the window glass 5 by the connecting member 13.

Further, a rotating drum (not shown) is rotatably supported on the inner surface of the inner panel 2 on the front side of the cable guide groove 7 (guide member 6), and both ends of the cable member 10 are wound around the rotating drum. It is fixed. Further, the support shaft of the rotating drum passes through the inner panel 2 and extends toward the passenger compartment, and a regulator handle 14 is attached to the end of the support shaft. The cable member 10 is moved up and down between the pulleys 9 by rotating the rotating drum, and the window glass 5 is opened and closed by the up and down movement of the cable member 10.

On the other hand, the roller guide groove portion 8 of the guide member 6
consists of a groove-shaped guide rail with a substantially C-shaped cross section that is open to the outside of the door, and when roller members 16 and 18 (described later) roll within the roller guide groove 8, the cable member attachment force of the connecting member 13 is applied. The point, that is, the connection point to the cable member 10 is the cable member 1
0 line of action of the driving force, that is, the original cable member 10
It is formed into a predetermined bent shape so as to approximately match the position of.

Further, a first roller member 16 is rotatably supported at the upper end of the connecting member 13 attached to the lower part of the window glass 5 via a connecting shaft 15, and is extended substantially downward from the first roller member 16. A second roller member 18 is rotatably supported at the lower end of the connecting member 13 separated by a predetermined distance via a connecting shaft 17, and these two roller members 16 and 18 are rolled into the roller guide groove 8 of the guide member 6. It is movably fitted. Of the two roller members 16 and 18, the second roller member 18 located at the lower side has a thickness set to be approximately the same as the groove depth of the roller guide groove portion 8, as shown in FIG. The roller guide groove 8 is provided so as not to be displaceable in the door inward/outward direction (vehicle width direction). On the other hand, as shown in FIG. 4, the upper first roller member 16 is set to have a thickness slightly smaller than the groove depth of the roller guide groove 8, and is displaced in the inner and outer directions of the door within the roller guide groove 8. possible.

Further, at the upper inner edge of the door panel 1, that is, at the upper edge of the inner panel 2 and the outer panel 3 directly below the opening 4, the front and rear portions are arranged facing each other in the door outward and outward directions so as to be in sliding contact with the window glass 5, respectively. Two pairs of stabilizers 19, 19 and 20, 20 are attached. Therefore, when the window glass 5 is opened and closed, the two pairs of stabilizers 1
9, 19, 20, 20 and the roller guide groove 8 of the guide member 6 regulate the displacement of the window glass 5 in the door-internal and external directions. The movement of the window glass 5 in the front and back direction of the door is restricted, and the bent shape of the roller guide groove 8 allows the window glass 5 to once be tilted forward when descending, and then rotated by being raised.

In FIG. 1, reference numeral 21 denotes a guide rail with a substantially U-shaped cross section that extends in the vertical direction and is attached to the front end of the door panel 1. The guide rail 21 is attached to the front end of the door panel 1 and has a substantially U-shaped cross section. It is something that is regulated. Further, 22 is a door lock device attached to the rear end inside the door panel 1.

Therefore, in the above embodiment, when the regulator handle 14 is rotated, the cable member 10 moves up and down within the cable guide groove 7 of the guide member 6, and the cable member 1
0 moves up and down, the window glass 5 connected to the cable member 10 via the connecting member 13 moves up and down, and the door window is opened and closed. Further, as the window glass 5 moves up and down, the first and second roller members 16 and 18 at the lower part thereof roll within the roller guide groove 8 of the guide member 6, and the window glass 5 moves between the stabilizer bars 19 and 20.
The movement of the window glass 5 when raised and lowered is regulated to a predetermined state by the guiding action of the roller guide groove 8 on the roller members 16 and 18 and the guiding action of the stabilizer 19 and 20 on the glass 5.

That is, in this case, while the two roller members 16 and 18 at the bottom of the window glass 5 are arranged substantially vertically, the roller guide groove 8
are bent into a predetermined shape, so when the window glass 5 is lowered, the positions of the roller members 16 and 18 within the roller guide groove 8 are relatively displaced;
Due to the relative displacement of the roller members 16 and 18, the window glass 5 moves downward while once tilting forward, and after moving downward for a predetermined distance, moves downward while standing up to its original position. This movement of the window glass 5 allows the window glass 5 to be lowered to the bottom of the door panel 1 and stored without interfering with the door lock device 22 at the rear end of the door panel 1.

Furthermore, since the roller guide groove 8 is integrally joined to the cable guide groove 7 to form the guide member 6, the strength of the roller guide groove 8 is significantly increased compared to when both the grooves 7 and 8 are separated. This increases the rigidity of the guide system, and the front and rear stabilizers 1 prevent the window glass 5 from moving in and out of the door.
9, 20 and the roller guide groove portion 8, stable and reliable regulation can be achieved.

Furthermore, while the lower second roller member 18 is supported by the roller guide groove 8 so as not to be displaceable in the door-outside direction, the upper first roller member 16
are supported in the roller guide groove portion 8 so as to be displaceable in the same direction, so that the displacement of the window glass 5 in the door-internal and external directions is always caused by the stabilizers 19, 20 and the second stabilizer located further away from both the stabilizers 19, 20. It is regulated by three support points with the two roller members 18. Therefore, by supporting the window glass 5 by the minimum necessary support points, the window glass 5 will not be distorted when moving up and down, and the window glass 5 can be opened and closed smoothly.

(Second Embodiment) FIGS. 7 and 8 show a second embodiment of the present invention, which is applied to a rear door of an automobile.
Note that the same parts as in FIGS. 1 and 2 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

That is, in this embodiment, a guide member 6' extending substantially vertically is installed in a door panel 1' of a rear door of an automobile, and the guide member 6' is connected to the cable guide groove 7 and the rear edge of the cable guide groove 7. and a roller guide groove 8' which is integrally joined to the cable guide groove 7 and extends below the cable guide groove 7. The cable guide groove 7 accommodates a vertically stretched cable member 10 that moves up and down as the regulator handle 14 is rotated. The upper part of the connecting member 13 is connected to the cable member 10, and the connecting member 13
is attached to the lower end of the window glass 5, and is configured to move the window glass 5 up and down as the cable member 10 moves up and down as the regulator handle 14 is rotated.

Further, almost the entire roller guide groove 8' of the guide member 6' is formed in a straight line parallel to the cable member 10, and only the lower end portion extending below the cable guide groove 7 is bent rearward. By forming only the lower end portion to be bent, the point of application of the cable member on the upper part of the connecting member 13 is set so as not to deviate greatly from the line of action of the driving force when the window glass 5 moves to the lower end position. Also,
In the roller guide groove 8', first and second rollers are rotatably attached to the connecting member 13 at the bottom of the window glass 5 at a predetermined distance apart in the vertical direction.
Two roller members 16 and 18 are fitted in a rotatable manner to restrict the movement of the window glass 5 in the front-rear direction when the window glass 5 is opened and closed, and the curved shape of the roller guide groove 8' prevents the window glass 5 from moving when the window glass 5 is lowered. It is configured to be tilted forward and rotated at its descending end position.

Reference numeral 23 denotes a guide member attached to the inner front end of the door panel 1', which, like the guide rail 21 in the first embodiment, restricts the displacement of the front edge of the window glass 5 in the inward and outward directions of the door. Furthermore, a tire house notch 24 is formed at the rear end of the door panel 1' to avoid interference with the vehicle body tire house that accommodates the rear wheels.

Therefore, in this embodiment, the window glass 5
When the window glass 5 is lowered, due to the bent shape of the roller guide groove 8' of the guide member 6', the window glass 5 descends in a straight line until it reaches its lowering end position, and when it reaches the lowering end position, it tilts forward. Then, insert the windshield 5 into the tire house notch 2.
It can be stored in the inner bottom of the door panel 1' while avoiding interference with the door panel 4.

Further, in this case, as in the first embodiment, since the roller guide groove 8' of the guide member 6' is integrally joined to the cable guide groove 7, its strength can be increased, and the window glass 5 It is possible to stably and reliably regulate the displacement of the door in the inward and outward directions. Moreover, since the upper first roller member 16 is supported in the roller guide groove 8' so as to be displaceable in the door-internal and external directions, the displacement of the window glass 5 in the door-internal and external directions is caused by the stabilizers 19, 20 and the second roller member 18. Therefore, it is possible to prevent twisting when moving up and down.

In each of the above embodiments, the roller guide groove 8,
8' is integrally joined to the cable guide groove 7 to constitute the guide members 6, 6', but it goes without saying that both may be integrally formed by roll forming or the like.

(Effects of the invention) As described above, according to the invention, in a cable-type window glass lifting device, a cable guide groove for storing a cable member and a bent roller guide groove are formed in a door panel of an automobile door. In addition, a plurality of roller members attached to the lower part of the windshield at a predetermined distance in the vertical direction are fitted in the roller guide groove so that the roller members can roll freely. Since the window glass can be rotated in the front and rear directions of the door when going up and down by rolling movement at the door, the window glass can be moved up and down while tilting back and forth, making it lightweight and compact. While adopting a cable-type window glass lifting device and using a simple guide mechanism, the window glass can be stored in the door panel while avoiding the door lock device and tire house notch of the door panel.
Further, since the strength of the roller guide groove is increased by integrating with the cable guide groove, the rigidity of the guide system can be increased, and the displacement of the window glass in the door/outside direction can be stably regulated.
