Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door window regulator for opening and closing a window glass of an automobile door.

A car door is equipped with a window that has a windshield, and when a handle attached to the inside of the door is rotated, a regulator arm that is linked to the handle rotates and the windshield moves up and down. It is designed to open and close using the following steps. According to such a door window regulator, water flows from the peripheral edge of the window glass to the regulator arm during a car wash or the like, and a portion of this water is further transmitted to the base of the regulator. This base is placed between the inner panel and outer panel of the door, but since it is screwed to the inner panel, it has the disadvantage that water often leaks into the room through the screw insertion holes. . Conventionally, countermeasures such as attaching a vinyl cover to the attachment part of the base have been taken, but such a structure has the problem of being troublesome to assemble and not being sufficiently effective in preventing water leakage.
Also, in order to solve this problem, it is conceivable to attach a halved cover having a water draining function to the regulator arm, as shown in, for example, Japanese Patent Application Laid-Open No. 54-159924. In this case, water leaks from the joint surface of the covering and the joint between the covering and the covered member, making it impossible to reliably prevent water leakage. Furthermore, if the covering is attached to the surface in this way, the covering may interfere with nearby parts, making it difficult to downsize the door window regulator, or increasing the number of parts, resulting in higher costs. There is also a problem.

The present invention has been developed in view of these problems, and includes a method of providing a water cutter with projections, notches, etc. on the lower edge in the longitudinal direction of the regulator arm that constitutes the door window regulator. It is something that Therefore, the water is drained by this draining portion, and no water flows to the base of the regulator, etc., and no water leaks to the inside of the door.

An embodiment in which the present invention is applied to a window regulator for a side door of an automobile will be described below with reference to the drawings. As shown in FIG. 1, a window 3 consisting of an opening is formed in the upper part of the door 1, and a window glass 4 is attached to this window 3 so as to be movable up and down. The window regulator 5 for opening and closing the glass 4 constitutes the door 1 with an inner panel 6 and an outer panel 7 (see FIG. 3).
It is placed between.

As shown in FIGS. 1 and 2, the wind regulator 5 includes a regulator arm 8 and a sub-arm 9 that intersect with each other in an X-shape. Note that the sub-arm 9 is divided into two parts, an upper part and a lower part, and these parts are integrally connected to each other via pins 10. This pin 10 is rotatably fitted to the regulator arm 8. Rollers 11 and 12 are attached to the tips of the regulator arm 8 and the sub-arm 9, respectively, and these rollers 11 and 12 are engaged with grooves in the glass bottom channel 13. Note that the bottom channel 13 is attached to the lower end of the window glass 4 via a receiving metal fitting 14. Further, a roller 15 is attached to the base end side of the sub-arm 9, and this roller 15 engages with a groove of a guide channel 16. Note that the guide channel 16 is fixed to the inner surface of the door inner panel 6 (the right side of the panel 6 in FIG. 3).

There is a pin 1 on the base end side of the regulator arm 8.
7 is fixed, and this pin 17 allows the regulator arm 8 to connect to the base 18 of the regulator 5.
is rotatably supported. Note that the base 18 is also fixed to the inside of the inner panel 6 with screws in the same manner as the guide channel 16. A slit 19 is formed in this pin 17,
A coiled spring 20 is attached between this slit 19 and a locking piece 21 on the base 18 side. This coiled spring 20 imparts a rotational moment to the regulator arm 8 that substantially balances the weight of the window glass 4. Further, a segment gear 22 is welded and fixed to the proximal end of the regulator arm 8. This gear 22 meshes with a pinion 24 fixed to an operating shaft 23.
The operating shaft 23 is rotatably supported by the base 18, and has a regulator handle 25 attached to its tip via a serration.

The above regulator arm 8 and sub arm 9
Protrusions 26, 2 on the lower longitudinal edge near the upper end.
A drain section consisting of 7 is formed. These protrusions 26 and 27 are for draining water that has been transmitted from the peripheral edge of the window glass 4 to the arms 8 and 9 via the receiving metal fitting 14 and the bottom channel 13, and allowing it to fall to the lower part. As shown in FIG. 3, an opening 28 for removing the drain is formed in the lower part of the door 1. Further, a side sill 29 is arranged on the lower side of the door 1. side sill 2
The upper surface of 9 is a sloped surface 3 that slopes downward toward the outside.
It's becoming 0. Note that a floor panel 31 is fixed to the inner side surface of the side sill 29.

Next, the operation of the regulator 5 having the above configuration will be explained. When opening or closing the window glass 4, the handle 25 may be rotated. As a result, the operating shaft 23 and pinion 24
rotates, and this rotation is transmitted to the regulator arm 8 via the segment gear 22. Therefore, the regulator arm 8 and the sub-arm 9 are both rotated, and the rollers 11 and 12 and the bottom channel 1 are rotated together.
3 and the receiving metal fitting 14, the window glass 4 moves upward or downward. In this way, the window glass 4 is opened and closed.

During car washing or the like, water flows along the peripheral edge of the window glass 4 through the receiving fitting 14 and the bottom channel 13 to the regulator arm 8 and sub-arm 9. However, since these waters flow along the lower longitudinal edges of the arms 8, 9, they are cut by the protrusions 26, 27, and these protrusions 26, as indicated by arrows 32 in FIGS. , 27 will fall downward from the tip. In other words, water is the base 1 of regulator 5.
8 or the inner panel 6 of the door 1 as shown in FIG.
and the outer panel 7. This water then passes through the drain opening 28 at the bottom of the door 1, flows over the slope 30 of the side sill 29, and is discharged outside the vehicle.

In this way, the wind regulator 5 of this embodiment
According to the above, since the water is drained by the protrusions 26 and 27 and falls, the water penetrates the inner panel 6 of the door 1 through the mounting hole of the base 18 or the guide channel 16, and leaks into the interior of the vehicle. disappears. Further, by providing the draining portion consisting of the protrusions 26 and 27, there is no need to take waterproof measures near the mounting hole of the base 18 or the guide channel 16, making assembly easier.

FIG. 4 shows a modification of the above embodiment, in which notches 35 are formed in the regulator arm 8 and the sub-arm 9 to serve as draining portions instead of the projections. Therefore, this cutout 35 allows the arms 8 and 9 to be passed through the glass 4 in the same manner as in the above embodiment.
It is possible to drain the water that has flowed into the tank, and it is possible to achieve the same effects as in the above embodiment.

As mentioned above, the present invention has a drain section on the lower longitudinal edge of the regulator arm, so this drain section blocks the flow of water and prevents water from flowing inside the door. Leakage can be effectively prevented. Furthermore, since there is no need to provide waterproofing measures to the mounting portion of the regulator mechanism, assembly is facilitated. Furthermore, since the drainer can be configured by simply providing a protrusion or a recess on the lower edge of the regulator arm, there is no need to prepare and assemble independent parts, and an increase in cost can be prevented. Furthermore, since the water cutter is formed by providing unevenness on the lower edge of the regulator arm, the water cutter can be provided without interference between parts provided on the side of the regulator arm and the water cutter. Therefore, the size of the door window regulator does not increase.
