BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg device for a washing machine.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for improved operability of adjusting legs when installing a floor of a washing machine.

Conventionally, a leg device of this type of washing machine has a configuration as shown in FIGS. Hereinafter, the configuration will be described with reference to the drawings. As shown in the figure, the adjusting leg 2 disposed below the outer frame 1 of the washing machine is formed by a large diameter portion 2a and a shaft portion 2b. Adjustment leg 2
The elastic body 3 is mounted on the large diameter portion 2a, and the clutch spring 4 is wound around the shaft portion 2b. The reinforcing plate 5 has, at its body, a square hole 5a for locking one end of the clutch spring 4 and a square hole 5b for allowing the other end of the clutch spring 4 to be rotatable. 5c through which the shaft part 2b is inserted
Are formed and screwed to the outer frame 1. An operation plate 6 is engaged with the tip of the clutch spring 4, and a coil spring 7 is mounted on the shaft 2b.

Next, the operation will be described. By rotating the operation plate 6 when the washing machine is installed on the floor, the inner diameter of the clutch spring 4 is enlarged, and the wound state with the shaft portion 2b is released.
The coil spring 7 receives a compressive force due to the weight of the washing machine, and the adjusting leg 2 keeps the allowance from the reinforcing plate 5 in balance with the other legs of the outer frame 1. Then, when the turning force of the operation plate 6 is removed, the clutch spring 4 and the shaft portion 2b are wound again, and the allowance of the adjustment leg 2 from the reinforcing plate 5 is maintained.

[0005]

However, in the above-described conventional configuration, the winding state changes due to the change in the interference due to the dimensional variation in the outer diameter of the shaft portion 2b and the inner diameter of the clutch spring 4, so that the square hole 5b is formed. There is a problem in that the angle of the rotatable tip portion 4a varies, and the position of the operation plate 6 varies, resulting in poor operability.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problem, and provides a leg device which can maintain the position of the operation portion even when the interference between the adjusting leg and the clutch spring changes, thereby improving the operability. With the goal.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an adjusting leg disposed at a lower portion of a frame of a washing machine;
A clutch spring that is wound around the outer periphery of the adjusting leg and applies a force to the end to release the wound state with the adjusting leg, and a coil spring that expands and contracts by receiving a compressive force due to the weight of the washing machine, A mounting plate having an arc-shaped elongated hole rotatable about the adjustment leg as an axis and locking one end of the clutch spring; and And a rotatable adjustment lever.

[0008]

According to the above construction, since the mounting plate is provided with the arc-shaped long hole, the angle of the mounting plate can be adjusted even if the interference between the adjusting leg and the clutch spring changes, and the position of the lever can be adjusted. Can be kept constant.

1 to 3 show an embodiment of the present invention.
This will be described with reference to FIG. In this embodiment, the same components as those of the conventional example are denoted by the same reference numerals, and the description thereof will be omitted. As shown in the figure, a long hole 10a is formed in the center of a reinforcing plate 10 fixed to the lower portion of the outer frame 1, and the long hole 10a is formed.
Is attached to the mounting plate 11. The mounting plate 11 has a cylindrical portion 11a for vertically moving the adjusting leg 2 therethrough, an engaging portion 11b for locking the lower end of the clutch spring 4, an arc-shaped elongated hole 11c, and the like. Lever 12 is cylindrical boss 12
a, a hole 12b, an operation portion 12c, a circular flange portion 12d, and the like. The clutch spring 4 is mounted on the center of the cylindrical boss 12a, and the adjusting leg 2 moves up and down through the hole 12b. A latch hole 12e is provided in the operation portion 12c to lock the upper end of the clutch spring 4, and the distal end of the clutch spring 4 is
It protrudes from the long hole 1a formed in the side wall. Reinforcement plate 1
A circular flange portion 12 d is sandwiched between the mounting plate 11 and the mounting plate 11 to be rotatable. A holding plate 13 is inserted into the mounting plate 11 and screwed to the reinforcing plate 10. The clutch spring 4 is attached to the mounting plate 11.
After the holding plate 13 is attached to the lower portion of the mounting plate 11, the lever 12 is rotated so that the inner diameter of the clutch spring 4 is increased, and the adjusting leg is loosely fitted with the coil spring 7. 2 is inserted. The operating portion 12c of the lever 12 is inserted through the elongated hole 10a so as to protrude from the elongated hole 1a and be rotatable. The position is set while rotating the mounting plate 11, and the holding plate 13 is screwed to the reinforcing plate 10.

As described above, in the leg device of the washing machine according to the embodiment, since the mounting plate 11 is formed with the arc-shaped long hole 11c, even if it is rotated to adjust the angle of the mounting plate 11,
The position of the tightening hole 10b formed in the reinforcing plate 10 and the position of the tightening hole 13a formed in the holding plate 13 are the movable range of the elongated hole 11c, and the movable range is determined by the outer diameter of the adjusting leg 2 and the clutch spring 4.
Since the setting is made in consideration of the variation range of the inner diameter, the screwing of the holding plate 13 and the reinforcing plate 10 can be assembled without any obstacle. Therefore, even if the interference between the adjusting leg 2 and the clutch spring 4 changes, the position of the lever 12 in the elongated hole 1a of the outer frame 1 can be kept constant.

[0011]

As is apparent from the above embodiment, the leg device of the washing machine according to the present invention has an adjusting leg provided at the lower portion of the outer frame of the washing machine, and an end wound around the adjusting leg. A clutch spring for releasing the wound state of the adjusting leg by applying a force; and a coil spring that expands and contracts by receiving a compressive force due to the weight of the washing machine, and is rotatable around the adjusting leg as an axis. A mounting plate having an arc-shaped elongated hole and locking one end of the clutch spring, and an adjustment lever locking the other end of the clutch spring and rotatable around the adjustment leg as an axis are provided. With this configuration, the angle of the mounting plate can be set arbitrarily even if the mounting angle of the lever with respect to the mounting plate after insertion varies due to variations in the outer diameter of the adjustment leg and the inner diameter of the clutch spring. Can be out of the lever The position of the side wall slot always can be kept operating position easy, thereby improving the operability of the adjustment.
