DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window regulator device. More specifically, the present invention relates to a device for preventing abnormal noise caused by a window glass falling inside (to the rear) of a vehicle.

[0002]

2. Description of the Related Art A so-called wire system in which a slider base for supporting a window glass of an automobile is moved upward and downward by a wire while being guided by a guide rail to open and close the window glass. Is provided.

[0003] In a wire type window regulator device, the wires respectively led in the vertical direction from the slider base are changed in direction by the pulleys at the upper and lower ends of the guide rail, and then converted into a single wire. It is connected to a winding device, and by driving the winding device, a tensile force is applied to the wire. The driving of the winding device is performed by manually operating a handle connected to the winding device, or
This is performed by operating a motor connected to the winding device.

[0004]

In a wire type window regulator device, a lower end of a window glass is supported by the slider base, and an upper end of the window glass is supported by a window frame of a door panel. It is configured as follows. Therefore, when the window glass is lowered from the top dead center, the upper end is separated from the window frame and becomes free, losing support. When the door panel is strongly closed in this state, the impact causes the upper end of the window glass to fall down toward the passenger compartment (rear), and the upper end of the guide rail located behind the window glass (toward the passenger compartment) is strongly applied. Hit. As a result, abnormal noise is generated, and in an extreme case, the window glass is damaged.

An apparatus disclosed in Japanese Utility Model Application Laid-Open No. 2-129584 is disclosed as an apparatus for preventing such a problem. In this device, an elastic body is provided on the front surface of a pin rotatably supporting a pulley at an upper end of a guide rail, and an upper end portion of a window glass which falls down to a vehicle compartment side as described above is provided.
This is a device to be received by the elastic body.

In the apparatus described in Japanese Utility Model Laid-Open Publication No. 2-129584, an elastic body is provided on the front surface (the surface facing the outside of the vehicle and the surface facing the window glass) of the pin of the pulley. Therefore, when the slider base is raised to the upper limit position, the elastic body overlaps the slider base together with the pulley. For this reason, the height of the elastic body located on the back surface side of the slider base toward the window glass (front) is limited so that the elastic body does not obstruct the slider base. Therefore, the above-described effects of preventing abnormal noise and damage are reduced.

In the apparatus disclosed in Japanese Utility Model Laid-Open Publication No. 2-129584, a pin for pivotally supporting the pulley is attached by caulking to the upper end position of a guide rail, and the front surface of the pin (facing the outside of the vehicle). Surface, the surface facing the window glass) is attached to the elastic body. From the drawings in the above publication, it is understood that the attachment of the elastic body is performed by insertion into the concave portion on the front surface of the pin or by vulcanization bonding. Is done. For this reason, it is considered that the elastic body is easily detached from the concave portion on the front surface of the pin.

In the device described in Japanese Utility Model Laid-Open No. 2-129584, an elastic body is provided on the front surface (the surface facing the outside of the vehicle and the surface facing the window glass) of the pin of the pulley. Since the grease is applied between the pulley and the pin, the grease easily adheres to the elastic body, and therefore has the disadvantage that the grease easily adheres to the window glass. .

The present invention has been made in view of the above circumstances. That is, when the door panel is strongly closed, the noise and damage caused by the window glass falling down toward the passenger compartment (rearward) and strongly hitting the upper end of the guide rail can be reliably prevented, and the elastic body can be prevented from falling off. It is an object of the present invention to provide a device which can prevent the grease from attaching to the window glass.

[0010]

According to the present invention, a slider base movably mounted on a guide rail provided in a door panel of an automobile is guided vertically from the slider base to guide rails. A window regulator device that moves up and down the window glass supported by the slider base by moving the window glass supported by the slider base up and down by pulling up and down by a pulling force of a wire connected to a wire winding device via pulleys at upper and lower ends. A support member for supporting the pulley at the upper end of the guide rail; a receiving hole for rotatably supporting the center axis of the pulley;
A substrate mounted parallel to the rail surface at the upper end of the rail;
An overhanging portion provided to extend from the substrate to the side (substantially in the same plane as the substrate) which is not covered by the pulley; and to project toward the window glass side (forward). And a resilient member mounted on the overhang portion.

[0011]

When the window glass is lowered and the door panel is strongly closed in a free state from the window frame, the impact causes the window glass to fall toward the passenger compartment (rear). However, at the upper end behind the window glass (the side on which it falls down), an elastic body mounted on an overhang of the support member beside the substrate is located. Therefore, the window glass does not hit the guide rail but hits the elastic body. Therefore, generation of abnormal noise
The damage of the window glass is prevented.

[0012]

Embodiments of the present invention will be described below. FIG. 1A is a front view of a pulley support member 20 used in the embodiment, and FIG. 1B is a view taken in the direction of the arrows BB in FIG. FIG.
FIG. 3 shows an elastic body 21 used for the pulley support member 20, and FIG. 3 is a view of the entire configuration of the embodiment device as viewed from the rear (in the passenger compartment). 4 and 5 show a state where the apparatus of the embodiment is attached to the door panel 52. FIG.

[1] Overall Structure of Window Regulator Device As shown in FIGS. 4 and 5, the window regulator device comprises a slider base 10 supporting a window glass 51 for an automobile, and Inside the door panel 52 (outer panel 52
This is a device for raising and lowering the window glass 51 by moving the window glass 51 upward or downward by the guide rail 13 provided vertically in a space surrounded by the inner panel 52A and the inner panel 52A.

The window glass 51 is at the upper limit position (top dead center).
The upper end is supported by the outer frame 53B and the inner frame 53A, and the lower end is supported by the slider base 10. However, as it descends out of the upper limit position, it gradually loses its support on the upper end side, and when it reaches the lower limit position (bottom dead center), it is only supported by the slider base 10 on the lower end side. For this reason, when the door panel is strongly closed in this state, the upper end side of the window glass 51 falls into the inside of the vehicle (rearward) with strong momentum.

The upward or downward movement of the slider base 10 is achieved by rotating the winding drum 31a of the wire winding device 31 in the forward or reverse direction as shown in FIG. Poo
The upper wire 11 is moved upward through the wire 15 or the lower wire 16
This is done by pulling the lower wire 12 downward through. The wires 11, 12 are housed in the outer cables 11a, 12a at positions off the guide rail 13, respectively. In this apparatus, the forward and reverse rotation of the winding drum 31a of the wire winding device 31 is electrically performed by using a motor 32. This operation is performed by connecting an operation handle to the winding drum 31a. , Manually.

[2] Pulley support member 20 As described above, the direction of the upper wire 11 is changed by the upper pulley 15 at the upper end of the guide rail 13, and the winding drum of the winding device 31 is wound. The upper pulley 15 is rotatably supported on the upper end of the guide rail 13 by a support member 20 having an elastic body 21 as shown in FIG. I have. The presence of the elastic body 21 prevents generation of abnormal noise and damage to the window glass 51 when the upper end side of the window glass 51 falls down inside (rearward) with strong force.

The support member 20 is provided on the upper end of the guide rail 13 with a resin substrate 23 attached in parallel with the rail surface, and is provided on the side of the substrate so as to extend from the substrate 23 in substantially the same plane as the substrate. And a rubber elastic body 21 mounted on the extended portion 23b. The attachment of the elastic body 21 is performed by inserting the elastic body 21 into a through hole 23e provided in the overhang 23b. That is, as shown in FIG. 2, the elastic body 21 includes a head 21a having a large diameter, a constricted central portion 21b, and a leg 21c having a large diameter at the central portion 21b and a small diameter at a distal end. By inserting the central portion 21b into the through hole 23e by inserting the central portion 21b into the through hole 23e from the distal end side of the portion 21c.

At the approximate center of the substrate 23, an upper pulley 15 is provided.
A receiving hole 23a is formed for rotatably supporting the central axis of the shaft. A wire guide portion 23c is formed in a position closer to the inside of the projecting portion 23b of the substrate 23 in a tangential direction of the upper pulley 15, and the wire guide portion 23c has a guide groove 23d.
Is provided.

Since the support member 20 configured as described above is attached to the upper end of the guide rail 13, the window glass 51 is moved to the outer frame 53B and the inner frame 53.
Even if the door panel 52 is strongly closed in this state, the upper end side of the window glass 51 hits the head 21a of the elastic body 21 and the guide rails. Because it does not hit 13
The generation of the abnormal noise and the damage of the window glass 51 are prevented.

[0020]

As described above, according to the present invention, the door panel is strongly closed with the window glass lowered and the vehicle interior (rear) is closed.
Even if it falls down, there is an elastic body behind it. For this reason, the window glass does not hit the guide rail but hits the elastic body. Therefore, generation of abnormal noise and damage to the window glass are prevented.

Further, since the above-mentioned elastic body is mounted on a projecting portion provided at a position where there is no pulley, it is not at a position where the slider base is obstructed, and is located outside the vehicle (on the side of the window glass). , Forward). Therefore, it is possible to reliably prevent the window glass from hitting the guide rail. Further, the elastic body is provided on the overhang portion, and is not provided on the front surface (the surface facing the outside of the vehicle) of the pivot of the pulley. For this reason, the mounting method is not limited. That is, it can be mounted in a reliable manner without falling off during use. Further, since the elastic body is provided apart from the pulley, there is no possibility that the grease adheres to the elastic body, and therefore, there is no possibility that the grease adheres to the window glass.
