Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention secures a slider to a geared cable that slides in a longitudinal direction in a guide tube so that the slider can be moved up and down, and a notch in the guide tube of the slider. The present invention relates to a window opening / closing device for an automobile, in which a portion protruding from the groove to the outside is connected to a glass plate and the glass plate is moved up and down by a reciprocating drive of a geared cable to open and close a window hole.

2. Description of the Related Art Problems to be Solved by Conventional Techniques and Inventions Conventionally, as a window opening / closing device for an automobile as described above, a substantially vertical conduction guide portion is provided below a window hole and connected to a drive device provided with a handle or the like. , A guide tube having a shape in which an elevating guide part parallel to the elevating path of the glass plate is connected at its upper end with a curved part, and the elevating guide part is arranged so as to correspond to the central part of the glass plate in the horizontal direction. Then, a slider having a structure in which one slider fixed to the geared cable is coupled to the lower end edge of the glass plate in the lifting guide is used.

However, in this conventional device, since the elevating guide portion is arranged so as to pass through the central portion in the horizontal direction of the glass plate,
Despite the fact that the conduction guide portion connected to the drive device is arranged at the end position in the horizontal direction of the glass plate, it is not possible to secure a large gap between the conduction guide portion and the elevating guide portion, and both guide portions are provided. The curvature of the bent portion connecting the cables increases, and a large bending stress is generated in the geared cable at this bent portion, which not only reduces its durability but also
There is a drawback that a large frictional resistance is generated between the inner surface of the curved portion and a large driving force is required to slide the geared cable, and the glass plate is supported by one slider. Therefore, as the slider inclines by a small distance provided to prevent twisting between the inner peripheral surface of the guide tube and the slide plate, the glass plate tilts within the plate surface and rattles. There was a drawback that caused.

Means for Solving the Problems As a means for solving the above problems, the present invention is provided below a window hole opened and closed by raising and lowering a glass plate of an automobile.
The upper end of a substantially vertical conduction guide connected to a drive device including a handle and the upper end of a vertical guide formed with a notch groove in the length direction and parallel to the vertical path of the glass plate are bent. The main guide pipe connected by the section is fixed, the geared cable that is reciprocally driven in the length direction by the drive device is slidably inserted into the main guide pipe, and the notch groove in the length direction is formed. The auxiliary guide tube is fixed in parallel with the lifting guide portion and separated from the lifting guide portion toward the conduction guide portion, and is fitted tightly and freely through the notch groove in the lifting guide portion. The inner slider fixed to the geared cable and the inner slider fitted tightly and freely through the notch groove in the auxiliary guide tube are integrated with the lifting support fixed to the lower edge of the glass plate. The main guide pipe and the sub guide pipe Shift either one or both, and configured to the outer slider for integrally lifting its inner slider while sandwiching the thickness of the guide tube between the inner slider and fitted.

The operation and effect of the invention The invention has the above-mentioned structure, and when the geared cable is slid by the operation of the drive device, the inner slider moves up and down in the elevating guide part of the main guide tube, and the inner slider moves. When the inner slider inside the sub-guide tube connected to the upper and lower supports is integrally moved up and down, the glass plate is moved up and down to open and close the window hole. Since it is supported by the inner slider at two positions that are horizontally spaced apart, it is kept in a stable posture where it is difficult to tilt, and the inner slide is retained at the fitting portion between the inner slider and the guide tube. The outer slider, which moves up and down integrally with the moving element, is fitted onto the guide tube so that the wall thickness of the guide tube is sandwiched between the inner slider and the outer slider. Is tilted due to a slight gap between the guide tube and the guide tube to prevent twisting. Therefore, the angle that can be tilted is smaller than when the outer slider is not provided, and therefore, the backlash caused by the tilting of the glass plate in the plate surface is suppressed to a very small degree. There is an effect that can be. Further, since the glass plate is supported at two horizontally spaced positions by providing the auxiliary guide pipe in addition to the main guide pipe, the elevating guide part of the main guide pipe is electrically connected to the drive device side. Since it is possible to arrange the guide part with a large gap, it is possible to set the curvature of the bending part that connects both guide parts to a small value, which allows the bending stress of the geared cable in the bending part to be set. And the durability can be improved, and the frictional resistance between the curved portion and the inner peripheral surface can be reduced to allow the geared cable to slide with a small driving force.

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

In the figure, reference numeral 1 denotes a right rear door of a passenger car, in which a glass plate 3 closes a substantially rectangular window hole 2 which is opened at an upper position of the door 1 and an outside of the vehicle. It is mounted so as to be able to move up and down between a panel 4 and a window opening position housed in a housing space 6 between the panel 5 on the inside of the vehicle.

In the accommodation space 6, a main guide pipe 10 made of a metal pipe having a circular cross section and having a geared cable 8 slidably inserted in a hollow is provided with a vehicle inside panel 5 via brackets 11, 12 and 13. The main guide tube 10 is fixed to the upper end of the conduction guide portion 14 that extends obliquely downward from the upper position of the accommodation space 6 and the ascending / descending direction of the glass plate 3 behind the center of the glass plate 3 in the front-rear direction. And the upper end of the elevating guide portion 15 arranged in parallel with the upper end of the elevating guide portion 15 are connected by a curved portion 16 having an arc shape, and the conduction guide portion 14 has a handle 18 projecting into the vehicle. It is mounted so as to penetrate through a drive unit 17 fixed to the vehicle interior panel 5, and when the handle 18 is manually rotated, the geared cable 8 slides through a gear (not shown) and its connecting end. Rises in the lift guide 15. And summer to. Similarly, in the accommodation space 6, a sub-guide pipe 20 made of a metal pipe having a circular cross section and having a length substantially the same as the elevating guide portion 15 of the main guide pipe 10.
Is parallel to the elevating guide portion 15 of the main guide tube 10 in a plane parallel to the glass plate 3 and is located in front of the longitudinal center of the glass plate 3 and between the elevating guide portion 15. The bracket 11 that supports the main guide tube 10 in a spaced state.
It is fixed to the vehicle inner panel 5 via 12 and 12.

In the elevating guide portion 15 of the main guide pipe 10, an inner slider 24 made of synthetic resin, which is fitted in the elevating guide portion 15 in a substantially tight and slidable manner, is formed at the connecting end of the geared cable 8 by molding. It is fixed so as to move up and down integrally with the geared cable 8. The inner slider 24 has a lifting guide
A connecting plate portion 25 is formed by extending in the front-rear direction a portion projecting to the outside of the vehicle through a notch groove 22 formed along the length direction of the connecting plate portion 25. A pair of front and rear metal outer slides 26, 26 that form an arc shape concentric with the child 24.
Are mounted by fitting the respective connecting portions 27 into the connecting holes 28 of the connecting plate portion 25, and these outer sliders 26, 26 are attached.
The sliding contact plates 29, 29 made of synthetic resin and having an arc shape fixed to the inner peripheral surface thereof are slidably contacted with the outer peripheral surface of the elevating and lowering guide section 15 to leave a very small gap therebetween. The thickness of 15 is sandwiched between the inner slider 24 and the inner slider 24 so that the inner slider 24 and the inner slider 24 can move up and down integrally.
Reference numerals 26, 26 denote bolts 33 on the inner surface of the lift support body 30 fixed to the glass plate 3 by fitting the fitting groove 31 on the upper end surface to the lower end edge of the glass plate 3 and connecting them with the bolt 32. It is fixed by.

On the other hand, in the hollow of the auxiliary guide tube 20, an inner slider made of synthetic resin
38 is fitted in substantially tightly and freely slidably, and the inner slider 38 is attached to the connecting plate portion 39 that extends from the notch groove 36 along the length direction of the auxiliary guide tube 20 and extends in the front-rear direction. , A pair of outer sliders 40, 40 having the same structure as the outer sliders 26, 26 of the lifting guide portion 15.
However, the thickness of the sub-guide tube 20 is changed to the inner slider through the sliding contact plates 41, 41.
The inner slider 38 and the outer sliders 40, 40 are mounted so as to be lifted up and down integrally with the inner slider 38 while being sandwiched between them.
Is fixed by bolts 43 to the elevating / lowering support body 30 to which the inner slider 24 and the outer slider 26 on the elevating guide portion 15 side are fixed.

In the window opening / closing device configured as described above, when the geared cable 8 is slid by the rotation operation of the handle 18, the main guide tube 10
As the inner slider 24 and the outer slider 26 on the side move up and down,
The glass plate 3 is opened and closed by moving up and down the inner slider 38 and the outer slider 40 on the side of the auxiliary guide tube 20 that are integrally connected via the lifting support 30.

Here, since the glass plate 3 is guided and supported at two positions spaced apart in the front-rear direction, the glass plate 3 is more stable than the conventional one that is guided and supported at one position, and the forward tilt and the backward tilt occur. In addition, it is difficult for the lift guide 15
And a slight gap between the inner and outer peripheral surfaces of the auxiliary guide tube 20 and the inner sliders 24, 38 and the outer sliders 26, 40 to prevent twisting during up-and-down movement and to allow smooth sliding. Outer slider 2
By providing 6, 40, the tiltable angle of the inner sliders 24, 38 is smaller than in the case where the outer sliders 26, 40 are not provided. The angle at which the glass plate 3 can be tilted forward or backward within the plate surface is small, and the rattling of the glass plate 3 is very slightly suppressed.

Further, the conduction guide portion 14 of the main guide pipe 10 is also arranged at the front portion of the door 1 because the drive device 17 is set at the front portion of the door 1 for the reason of operating the handle 18. However, since the auxiliary guide tube 20 is arranged in a position in front of the elevating guide part 15 to guide and support the glass plate 3, the elevating guide part 15 is largely separated from the conduction guide part 14. Since it could be placed in the rear part, the conduction guide part
The curvature of the arc-shaped bending portion 16 connecting the 14 and the elevating guide portion 15 is small, so that the geared cable 8 bent in the bending portion 16 has a small bending amount and is bent. Since the value of the stress caused by is small, the service life is long, and the pressing force on the inner peripheral surface of the bent portion 16 of the bent geared cable 8 is small, so that the frictional resistance generated at the time of sliding can be suppressed small. The driving force required to perform the opening / closing operation can be small.

In the present embodiment, the lifting guide portion 15 and the sub-guide tube 20 are made of metal, but the inner slider 2 that slidably contacts the inner peripheral surfaces thereof.
4, 38 and sliding contact plates 29, 4 of the outer sliders 26, 40 slidingly contacting the outer peripheral surface
Since 1 and 1 are made of synthetic resin, the frictional resistance generated on the surface that slides up and down is small, and the generation of abnormal noise and galling when metal is slidingly contacted is prevented, and opening and closing of the window hole 2 is smooth. There are advantages to be done.

Similarly, in this embodiment, the lifting guide 15 and the auxiliary guide tube
Although the outer sliders 26, 40 are provided on both of the 20, the outer sliders may be provided on only one side of the elevating guide portion 15 and the sub guide tube 20.
