Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a window glass lifting device that moves the window glass of an automobile door up and down in order 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, for example,
There is a cable type type as disclosed in the above publication. In other words, this cable type is
The cable member (wire member) is stretched almost vertically within the door panel and connected to the lower end of the window glass via a connecting member, and the guide rail member guides the window glass up and down, and the cable member can be moved up and down. This device opens and closes the window glass by means of the door panel, and has excellent advantages such as being lightweight, occupying only a small space in the door panel, and having no fluctuation in operating force.

(Problems to be Solved by the Invention) By the way, when the windshield of the front door of an automobile is moved downward and stored in 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 panel. 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 conventional cable-type window glass lifting device described above has a low rigidity for holding the window glass, and it is difficult to move the glass up and down while tilting the glass, so there is a problem that the above movement of the window glass cannot be realized. It was hot.

The present invention was made in view of these points,
The main purpose is to improve the guide rail member for guiding the up and down movement of the window glass in the above cable type windshield lift device, which is lightweight and compact. To enable a window glass to be housed in a door panel while being tilted to avoid a door lock device, a notch for a tire house, etc.

(Means for Solving the Problems) In order to achieve the above object, the solving means of the present invention connects a cable member stretched substantially vertically within a door panel of an automobile door to a windshield glass via a connecting member. The lower end portions of the windshield are connected to each other, and the window glass is moved up and down by vertical movement of the cable member to open and close the window glass.

Furthermore, a first guide rail member extending linearly in the vertical direction adjacent to the side of the cable member; 1st to
A second member extending non-parallel to the guide rail member.
a guide rail member; and a first guide rail member, which is disposed in a positionally immovable manner at the lower part of the window glass, and is slidably supported by the first guide rail member so as to be non-swivelingly sandwiched therebetween. a second slider, and a second slider disposed in a positionally immovable manner at the bottom of the window glass at a position away from the mounting position of the first slider, and swingably supported by the second guide rail member. a slider, and the distance in the horizontal direction between the first and second guide rail members passing through either one of the sliders is less than the distance between the first and second sliders. A glass lift guide that is small in size and guides the window glass to rotate approximately within a vertical plane in the front-rear direction of the door due to the difference in the distance between the two guide rail members and the slider when the window glass is opened or closed. The structure is equipped with means.

(Function) With the above configuration, in the present invention, when the window is opened or closed, the window glass connected to the cable member is moved up and down by the vertical movement of the cable member in the glass elevating drive means. As the glass moves up and down, the first slider attached to the lower part moves inside the first guide rail member in the door panel, and the second slider moves inside the second guide rail member on the side of the first guide rail member. The window glass slides within the guide rail members, and is raised and lowered while being held by the door panel due to the guiding action of these two guide rail members. At that time, while the above two guide rail members are arranged non-parallel within the door panel, the distance between the two sliders at the bottom of the glass is constant, and the distance between the two sliders is Since the horizontal distance on the slider between both guide rail members is smaller, the window glass is regulated so that the distance between the positions of each slider on the corresponding guide rail member is always constant. Move up and down while In other words, by regulating the slider with the guide rail member, the window glass that moves up and down can be rotated to tilt forward or backward.

Further, the first slider is supported by the linear first guide rail member so as to be able to swing therebetween, so that the first slider is swingably supported by the linear first guide rail member. In addition, vibration of the glass due to the swinging of the slider relative to the guide rail member can be suppressed. Moreover, since the first guide rail member is linear, the sliding resistance of the first slider is small, and even if the window glass is tilted forward or backward, it can be raised and lowered smoothly.

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

1 to 4, reference numeral 1 denotes a door panel of a front door for an automobile, 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 is provided with inner and outer surfaces of the door panel 1. 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 regulator base 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.
Pulleys 7, 7 are pivotally supported at the upper and lower ends of the inner surface of the regulator base 6, and an intermediate portion of a cable member 8 (wire member) is stretched substantially vertically between the pulleys 7, 7. . In addition, in the middle part of the cable member 8, there is provided a cable at the lower end of the window glass 5.
A triangular plate-shaped connecting member 11 attached via a pair of bolts 9, 9 and nuts 10, 10 is connected, and the cable member 8 is connected to the lower end of the window glass 5 via the connecting member 11. ing.

In addition, a rotating drum (not shown) is mounted on the inner surface of the inner panel 2 on the front side of the regulator base 6.
is rotatably supported, and both ends of the cable member 8 are wound around and fixed to the rotating drum. The support shaft of the rotating drum extends toward the passenger compartment through the inner panel 2, and a regulator handle 12 is attached to the end of the support shaft. A glass lifting/lowering drive means 13 which rotates a rotating drum to move a cable member 8 up and down between pulleys 7, 7, and opens and closes a window glass 5 by moving the cable member 8 up and down.
is configured.

On the other hand, at the rear edge of the regulator base 6 on which the cable member 8 is stretched, a first guide rail member 14 having a substantially C-shaped cross section and opening outward from the door is arranged so as to be parallel to the cable member 8. arranged and integrally joined. Therefore, the first guide rail member 14 is disposed adjacent to the rear of the cable member 8 and extends linearly substantially in the vertical direction.

A first slider 15 made of a slider member is slidably supported on the first guide rail member 14, and the first slider 15 is a connecting member immovably attached to the lower part of the window glass 5. 11 via a connecting shaft 16 so as to be rotatable.

Further, on the inner surface of the inner panel 2 located a predetermined distance away from the first guide rail member 14 toward the rear of the door, there is provided a second guide rail having a substantially U-shaped cross section that is open to the outside of the door.
The guide rail member 17 is arranged and attached so as to extend substantially in the vertical direction, and the second guide rail member 17 is bent into a predetermined shape, so that the second guide rail member 17 is attached to the first guide rail member. 14 and is extended in a non-parallel state.

A second slider 18 made of a roller member is slidably supported on the second guide rail member 17,
The second slider 18 is rotatably supported by the tip of a bracket 20 via a connecting shaft 19, and the base of the bracket 20 is spaced a predetermined distance behind the door from the mounting position of the first slider 15. Attach two pairs of bolts 21, 21 to the bottom of the window glass 5 in the
and are immovably attached via nuts 22, 22.

The first and second sliders 15, 18
The distance in the horizontal direction between the first and second guide rail members 14 and 17 passing through either one of The distance between the first and second guide rail members 14 and 17 is smaller than the distance between the first and second guide rail members 14 and 17 when the window glass 5 is opened and closed.
The movement of the glass 5 is regulated by the guiding action on the second slider 15, 18, and the difference in distance between the two guide rail members 14, 17 and between the two sliders 15, 18 allows the window glass 5 to be moved approximately toward the front and back of the door. A glass lifting/lowering guide means 23 is configured, which rotates in a vertical plane of the direction and guides the window glass 5 so that it is once tilted forward when descending due to the bent shape of the second guide rail member 17, and then raised. has been done.

In FIGS. 1 to 3, stabilizers 24 and 25 are attached to the front and back positions of the upper end opening 4 of the door panel 1 so as to come into contact with the window glass 5, and restrict the displacement of the glass 5 in the door-outside and outside directions. It is something to do. Reference numeral 26 denotes a guide rail having a substantially U-shaped cross section and extending in the vertical direction, which is attached to the front end of the door panel 1, and which clamps the front edge of the window glass 5 to restrict its displacement in the door's inward and outward directions. . Further, 27 is a door lock device attached to the rear end of the door panel 1.

Therefore, in the above embodiment, when the regulator handle 12 is rotated, the cable member 8 moves up and down within the regulator base 6, and the up and down movement of the cable member 8 causes the cable member 8 to The window glass 5 connected via the connecting member 11 moves up and down to open and close the door window. In addition, as the window glass 5 moves up and down, the first and second sliders 15 and 18 at the bottom thereof slide within the first and second guide rail members 14 and 17, respectively, and the guide rail member 14 slides inside the first and second guide rail members 14 and 17, respectively. , 17 to guide the sliders 15, 18, the movement of the window glass 5 during elevation is regulated to a predetermined state.

That is, in this case, the first guide rail member 14 is arranged parallel to the cable member 8 in the regulator base 6, whereas the second guide rail member 17 is arranged non-parallel to the first guide rail member 14. The guide rail members 14 and 17 are bent into a predetermined shape so that the guide rail members 14 and 17 pass through one of the sliders 15 and 18 at the lower part of the glass 5 than the distance between the sliders 15 and 18 at the bottom of the glass 5. Since the distance in the direction is smaller, each slider 15, 18 moves toward its corresponding guide rail member 1 when the window glass 5 is lowered.
The sliders 15 and 18 are moved so that the distance between the positions at 4 and 17 is always constant, and a difference occurs in the amount of displacement of both the sliders 15 and 18. Due to the difference in the amount of displacement between the sliders 5 and 18, the window glass 5 once lowers while tilting and rotating forward about the first slider 15, and after descending a predetermined distance, it stands up to its original position. It moves downward while rotating. By rotating the window glass 5 in this manner, the window glass 5 can be lowered to the bottom of the door panel 1 and stored without interfering with the door lock device 27 at the rear end of the door panel 1.

In this embodiment, the first and second sliders 15,
18 are all immovably attached to the window glass 5, the reliability is lower than when the sliders are movably attached to the glass.
In turn, the reliability of the entire window glass lifting device can be improved.

In addition, while the window glass 5 moves up and down, the sliders 15 and 18 move in the door front and rear directions guided by the guide rail members 14 and 17, respectively, so that the movement of the glass when going up and down becomes smooth.
Design tuning becomes unnecessary.

Furthermore, since the window glass 5 is rotated as it is raised and lowered, the remaining area of the glass when the window is opened can be reduced compared to when the glass is moved in parallel in the vertical direction while maintaining the horizontal state. Even if it is a window glass lifting device,
The open feeling of the window can be improved. Furthermore, the support rigidity in the longitudinal direction of the vehicle body in the cable type windshield lifting device can be increased.

Further, the first guide rail member 14 has a substantially C-shaped cross section, and supports the first slider 15 so as to be slidable by sandwiching the first slider 15 with respect to the guide rail member 14 so as not to be able to swing. When the window glass 5 moves up and down, the first slider 15 does not swing relative to the guide rail member 14, and the vibration of the window glass 5 due to the swing can be effectively suppressed. can. Moreover, since the first guide rail member 14 is linear, the sliding resistance of the first slider 15 is small, and even if the window glass 5 moves up and down while tilting forward and backward, its movement can be performed smoothly. be exposed.

(Second Embodiment) FIGS. 5 and 6 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 to 3 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

That is, in this embodiment, a cable member 8 that moves up and down as the regulator handle 12 is rotated is stretched around a regulator base 6 that is attached to a door panel 1' of a rear door of an automobile.
The lower end of the window glass 5 is connected to the cable member 8 via a connecting member 11, and the window glass 5 is moved up and down by vertical movement of the cable member 8 as the regulator handle 12 is rotated. The glass lifting/lowering driving means 13 is configured as follows.

Further, behind the cable member 8 in the regulator base 6, a linear first guide rail member 14 extending substantially vertically in parallel with the cable member 8 is provided.
A first slider 15 attached to the connecting member 11 at the lower part of the window glass 5 is slidably supported on the first guide rail member 14.

Further, at a position a predetermined distance away from the first guide rail member 14 in the front direction of the door, a second guide rail member is bent so as to be non-parallel to the first guide rail member 14 and extends substantially in the vertical direction. 17 is attached, and a second slider 18 attached via a bracket 20 to the lower part of the window glass 5 at a position away from the attachment position of the first slider 15 slides on the second guide rail member 17. Glass elevating guide means 23 is movably supported, restricts its movement when opening and closing the window glass 5, and allows the windshield 5 to tilt forward and rotate when descending due to the bent shape of the second guide rail member 17. is configured.

Reference numeral 28 denotes a guide member attached to the inner front end of the door panel 1', which, like the guide rail 26 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 29 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
Due to the bent shape of the second guide rail member 17 and its non-parallel arrangement with the first guide rail member 14, the window glass 5 is lowered by the first slider 15.
The window glass 5 is moved downward while tilting forward with the window center at the center, and thus the window glass 5 can be stored in the inner bottom of the door panel 1' while avoiding interference with the tire house notch 29. In addition, the same effects as in the first embodiment can be obtained in other respects.

Note that in this embodiment, the second guide rail member 1
7 is formed into a bent shape and placed in front of the first guide rail member 14, but as shown in FIG. 1 behind the guide rail member 14, and both guide rail members 14,1
7' may be arranged in a non-parallel state with the first guide rail member 14 so that the distance between them decreases toward the bottom of the door, and the window glass 5 is tilted forward when descending in the same manner as above. It can be raised and lowered.

(Effects of the Invention) As described above, according to the present invention, in a cable-type window glass lifting device, a linear first guide rail member is provided in a position adjacent to a cable member in a door panel, and the first guide rail member is provided in a position adjacent to a cable member in a door panel. A second guide rail member is provided at a position away from the rail member and is non-parallel to the first guide rail member, and each of the two guide rail members has a slider attached and fixed to the bottom of the glass at a distance from each other. Support the slider and pass through the slider less than the distance between both sliders.
By reducing the horizontal distance of the guide rail members and regulating the movement of the window glass when it goes up and down by the difference in the distance between both guide rail members and between both sliders, the window glass can be moved easily. When opening and closing the door, it can be moved up and down while rotating back and forth in the vertical plane of the front and rear directions of the door.As a result, even though it is a lightweight and compact cable-type windshield lift device, it can also be used as a door lock device for door panels or a tire house cut-off. The window glass can be stored inside the door panel while avoiding chips and the like.

Moreover, since each slider is immovably attached to the window glass, the reliability of the sliders and the entire window glass lifting device can be improved. In addition, while the window glass moves up and down, the slider moves in the door front and rear directions, so the glass moves smoothly when going up and down, eliminating the need for design tuning. Furthermore, even with a cable-type window glass lifting device, since the window glass is rotated when going up and down, the remaining area of the glass when the window is opened is reduced compared to when the glass is moved up and down while moving in parallel, creating a feeling of openness. It is possible to increase the support rigidity in the longitudinal direction of the vehicle body. In addition, the linear first
Since the guide rail member supports the slider in such a way that it cannot swing relative to the guide rail member, it is possible to suppress the vibration of the window glass when the window glass moves up and down, and also to
Since the guide rail member is linear, the sliding resistance of the slider can be reduced, and even if the window glass is tilted forward or backward, it can be raised and lowered smoothly.
