Abstract

PURPOSE:To enable a window to be opened or closed smoothly with safety by arranging a second cable for pulling a bracket downward, and a first cable for pulling it upward, and by a setting a friction body coming in sliding contact with a guiderail. CONSTITUTION:When a second cable 8' engaged with a lock lever 6 is pulled downward from the closed state of a window glass 10, then pressure contact between a frictional body 7 fitted pivotally on the lock lever 6, and a guiderail 2 is released, and a bracket 3 is moved down, and the window glass 10 is opened. After that, when move-down operation is stopped, then the lock lever 6 is pulled upward with the energizing force of a lock spring 11, and the frictional body 7 comes in sliding contact with the guiderail 2 and is locked. Besides, when the bracket 3 is pulled upward with a first cable 8 from the released state of the window glass 10, then locking is automatically released, and the window glass 10 is moved upward. After that, when moving-up operation is stopped, then the lock lever 6 is pulled upward, and the frictional body 7 comes in sliding contact with the guiderail 2 and is locked.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a slide guide mechanism for a cable type window regulator used in vehicles such as automobiles. More specifically, the present invention relates to a slide guide mechanism for a cable type window regulator having a locking mechanism.

[Prior Art] Most conventional slide guide mechanisms for cable-type window regulators have a structure in which a slide shoe holds the guide rail, or a structure in which the slide shoe holds the guide rail. .

[Problems to be Solved by the Invention] However, in the above structure, an appropriate gap is required between the guide rail and the slide shoe in order for the slide shoe to slide on the guide rail. For this reason, lubricants such as grease are applied to the sliding parts to ensure smooth sliding, but strange noises occur every time the window glass is slid up and down, and the driver sometimes drives with the window glass partially open. The rattling of the vehicle often makes strange noises that cause discomfort to passengers. In addition, when the window glass is left partially open, if an excessive load is applied to the window glass, such as by someone resting an elbow on it or a child hanging down, that load will be transmitted directly to the cable, causing damage to the window regulator mechanism and cable. It is the cause.

In addition, the window glass operating means (has a built-in reverse prevention mechanism to prevent the window glass from being pried open, but in the unlikely event that the cable breaks, this mechanism will be completely useless and the window glass will not be able to be opened.) The glass has lowered to the bottom and opens when you want to keep it closed, such as during rain, strong winds, while driving on the highway, or when using an air conditioner in the summer. The remaining shortcomings cannot be avoided.

[Means for Solving the Problems] The present invention provides a slide guide mechanism for opening and closing a window glass in a cable-type window regulator used for vehicles, etc., which includes a guide rail and a slide guide mechanism slidably attached to the guide rail. a bracket; the bracket has at least one slide shoe having a sliding surface capable of slidingly contacting one inner wall surface of the guide rail; a lock lever having one end rotatably supported by a shaft; and the lock lever. - an elastic member that biases the lock lever in the locking direction; and at least one friction body that is normally in pressure contact with the other inner wall surface of the guide rail and that can be released from the pressure contact only during an opening/closing operation. is pivotally attached to the bracket, and a terminal fitting fixed to the end of the first cable extending in the longitudinal direction of the guide rail is locked in a locking hole at an appropriate position of the bracket, and a terminal fitting is locked in the locking hole near the friction body of the lock lever. A structure is adopted in which a locking hole is provided in the end of the second cable extending in the opposite direction (extending) to the first cable, into which a fixed terminal fitting is locked.

[Function] In the present invention, when the window glass is lowered from the closed state to open it, when the operating means (therefore, the second cable that is locked to the O-tsukuru lever) is pulled downward, the elastic member urges the window glass in the locking direction. As the lock lever is pulled downward, the pressure contact between the friction pair pivotally attached to the tip of the lock lever and the guide rail is released, the bracket is lowered and the window glass is opened, and the window glass can be lowered. When this is stopped, the lock lever is pulled upward by the biasing force of the elastic member, and at the same time, the friction body comes into sliding contact with the guide rail.
completely locked.

Next &: When raising the window glass to close it, use the operating means to pull the bracket upwards using the first cable.
Due to its structure, the lock can be automatically released and raised without moving the lock lever downward. When the lifting operation of the first cable is stopped, the lock lever is pulled upward by the biasing force of the elastic member, and the friction body comes into contact with the guide rail to complete the locking.

[Example code] Next, one embodiment of the present invention will be described with reference to the drawings.

The drawing is a partially cutaway front view of a main part of a slide guide mechanism for a cable type window regulator according to an embodiment of the present invention.

The bracket (3) in the slide guide mechanism (1) includes a slide shoe (4) having a sliding surface (4a) that slides into contact with one inner wall surface (2a) of the guide rail (2).
Further, one end of a lock lever (6) is pivotally supported by a shaft (5) at an appropriate position of the bracket, and is biased in the locking direction, that is, in the C-disengagement direction, by a lock spring (11). Said guide rail (2) at the end
A friction body (7) that comes into contact with the other inner wall surface [2b] is pivotally mounted. One end of the first cable (8) for sliding the window glass is locked in a locking hole (9) provided at an appropriate position of the bracket (3), and the other end of the second cable (8)
The end of the lock lever (6) is locked in a locking hole (6a) provided at an appropriate position, and the first cable and the second cable are connected to each other through a drive (not shown). essentially forming a loop through the device.

When closing a cable type window regulator using the slide guide mechanism (1) having such a structure by operating a drive device (not shown), when the first cable (8) is pulled in the direction A, the window glass (10) is closed. The friction body (7), which is usually pivotally mounted on the end of the lock lever (6), rises along the guide rail (2) on which the bracket (3) to which the lock spring (11) is attached is mounted. The inner wall surface (2b) of the guide rail (2) is
), but at this time, the bracket (3) slides in the direction A, so the lock between the friction body (7) and the inner wall surface (2b) of the kite rail is temporarily released, and the window glass ( 10) increases. When the window glass (10) is completely closed or raised to an appropriate position and stopped, the lock lever (6) immediately moves the friction body (7) to the guide rail ( Of 2), the lock is completed by pressing against the f14rl wall (2b).

Next, when opening the closed window glass, the second cable (8゛) is pulled in the direction of B forfeiture by the drive device.
First, the lock lever (6) rotates in the D forfeiture direction,
The friction body (7) is unlocked from the inner wall surface (2b) of the guide rail (2), and the window glass (1) can be lowered. At this time, as mentioned above, the first cable (8) and the second cable (8゛) form a loop, so the first cable (8) is suspended from above the window glass (10). Yes, the window glass will not fall. When the lowering operation of the window glass is stopped, the lock lever (6), which has been pulled downward by the second cable (8°), immediately becomes frictional due to the biasing force of the lock spring [11] in the C disengagement direction. Place the body (7) on the guide rail (2
) and lock it in contact with the inner wall surface (2b).

Due to the above-mentioned mechanism, when the window glass slides, play is felt between the slide guide mechanism and the guide rail, but when the sliding stops, the sliding surface (4a) of the slide shoe (4) and the friction body (1) is the kite L/-/L, (
2) is pressed against the inner wall surfaces (2a, 2b) and locked in a tensioned state from the inside, so there is no play at all.

[Effects of the Invention] By adopting the mechanism of the present invention, even if a child rests his or her elbow on a half-open window glass or a child hangs down, the drive device and the There is no damage to the cable, and even if the cable breaks, the window glass will not fall, even when driving on a highway, during rain, or in strong winds.
Furthermore, this invention has the excellent effect of allowing you to drive safely and comfortably when you want to keep the window glass closed, such as when using an air conditioner in the summer.
