[0008]

However, in the window regulator having the above structure, the motor 10 and the drum 9 are
Are arranged on the side of the guide 1, so that the substantially triangular space formed by the guide 1, the wire 12 leading to the upper pulley 13, and the wire 12 leading to the lower pulley 14 becomes a dead space, and other parts provided in the door panel. There is a problem that the degree of freedom in arranging is reduced.

The present invention has been made in view of the above problems, and an object thereof is to provide a space-saving window regulator.

[0010]

DISCLOSURE OF THE INVENTION The present invention for solving the above-mentioned problems includes a guide provided along the ascending / descending direction of glass,
A slide member slidably engaged with the guide to which the glass is attached; a motor provided at one end of the guide; a turn guide provided at the other end of the guide; A drum that is provided at one end of the guide and is driven to rotate by the motor, and an intermediate portion is wound around the drum, one end of which is the slide member, and the other end of which is the turn guide. And wires that are respectively locked to the slide members.

[0011]

In the window regulator of the present invention, when the motor drives the drum, the drum rotates. As the drum rotates, one wire is fed from the drum and the other wire is wound on the drum. By the movement of the wire, the slide member moves along the guide, and the glass is moved up and down.

Since the drum and the motor for rotating the drum are provided at either end of the guide, the conventional window regulator, that is, the motor and the drum are arranged on the side of the guide. The space occupied by the window regulator is much smaller than that of a window regulator in which a substantially triangular space formed by the wire leading to the upper pulley and the wire leading to the lower pulley becomes a dead space, so that the space can be saved.

Further, in the conventional window regulator,
Although the turn guides were required at both ends of the guide, the window regulator of the present invention requires only the guides on the side where the drum is not provided, so the number of parts can be reduced.

Furthermore, since the length of the wire is small,
Costs can be reduced.

[0015]

Embodiments of the present invention will be described with reference to the drawings. 1 is a configuration diagram of an embodiment of the present invention, FIG. 2 is a sectional view taken along line BB in FIG. 1, and FIG. 3 is a sectional view taken along line CC in FIG.

In FIGS. 1 and 2, a guide 31 is provided along the ascending / descending direction of the glass 32 (the arrow direction in FIG. 1). The upper and lower parts of this guide 31 are on the vehicle body side.
It is attached to (door inner panel).

The rail portion 31a provided on the guide 31 is provided with a slider plate 36 as a slide member via two sliders 33 and 34 slidably engaged with each other. Further, the lower part of the glass 32 and the slider plate 36 are fixed to each other with the screw 37,
Can be moved up and down in the direction of the arrow along the guide 31.

A motor 38 is provided above the guide 31, and a drum 39 having a groove 39a spirally formed on a cylindrical surface is fixed to the output shaft of the motor 38. Four
Reference numeral 0 is a cover which is attached to the guide 31 with screws 41 and covers the drum 39.

An intermediate portion of a wire 42 is wound around the groove 39a on the cylindrical surface of the drum 39. One end of the wire 42 is directly locked to the slider plate 36, and the other end of the wire 42 is rotatably mounted on the lower portion of the guide 31 via a lower pulley (turn guide) 43. It is locked to 36.

Here, the locking structure between the slider plate 36 and the wire 42 will be described with reference to FIG. A rectangular hole 36a is formed in the slider plate 36, and the hole 3a
A box-shaped housing 50 having an open upper surface is attached to 6a by an injection molding method or the like.

Inside the housing 50, a brim portion 51 is formed.
Sliders 51 and 52 having a and 52a are slidably arranged. One end side and the other end side of the wire 42 are fitted in the housing 50 via bushes 53, 54 fitted to the side surfaces of the housing 50, respectively.

Further, the sliders 51, 52 are formed with through holes 51b, 52b through which the wires 42 are inserted in the axial direction, and the tips of the respective wires 42 are provided with retaining members 55, 56.
It is attached by a method such as caulking.

The slack of the wire 42 is removed by the urging force of the springs 57 and 58, one end of which contacts the inner wall surface of the housing 50 and the other end of which abuts the flanges 51a and 52a of the sliders 51 and 52, respectively. .

Next, the operation of the above configuration will be described. By driving the motor 38, the drum 39 rotates. By the rotation of the drum 39, the wire 42 on one side of the wires wound around the drum 39 is fed out from the drum 39, and the wire 42 on the other side is wound around the drum 39. The movement of the wire 42 causes the slider plate 36 to move along the guide 31, and the glass 32 is moved up and down.

According to the above structure, the conventional window regulator, that is, the motor and the drum are arranged on the side of the guide, and the substantially triangular space formed by the guide, the wire reaching the upper pulley, and the wire reaching the lower pulley is a dead space. The space occupied by the window regulator is much smaller than that of the conventional window regulator, and the space can be saved.

Further, in the conventional window regulator,
Although the turn guides were required at both ends of the guide, in the window regulator of this embodiment, the lower pulley 4 on the side where the drum 39 is not provided, that is, the lower portion of the guide 31.
Since only 3 is used, the number of parts is small.

Furthermore, since the length of the wire 42 can be reduced, the cost can be reduced. In addition, since there is no slack in the wire 42, the wire 4 can be inserted from the groove 39a of the drum 39.
2 never comes off.

The present invention is not limited to the above embodiment. Although the drum 39 is provided on the upper side of the guide 31 in the above embodiment, it goes without saying that it may be provided on the lower side of the guide 31.

Further, although the pulley is used as the turn guide, it is not limited to the pulley, and a semi-circular guide with which the wire is slidably contacted may be used.

[0030]

As described above, according to the window regulator of the present invention, by providing the drum and the motor for rotationally driving the drum on either end of the guide, the conventional window regulator, that is, Since the motor and drum are arranged on the side of the guide and the dead space is the approximately triangular space formed by the wire leading to the guide, the upper pulley, and the wire leading to the lower pulley, the window regulator occupies a much larger space. It becomes narrower and space can be saved.

Further, in the conventional window regulator,
Although the turn guides were required at both ends of the guide, the window regulator of the present invention requires only the guides on the side where the drum is not provided, so the number of parts can be reduced.

Furthermore, since the length of the wire is small,
Costs can be reduced.
