The present invention relates to an improvement in a clip structure stopper.

[0002]

2. Description of the Related Art Conventionally, a clip 1 of this kind having a clip structure is used.
As 0, for example, those having the structures shown in FIGS. 19 to 22 are known.

That is, the stopper 10 is located at the rear end side (FIG. 2).
1 on the right) and a plate-like holding portion 11b on the front end side (the left side in FIG. 21).
And an elastic piece 11 which is elastically deformable in the vertical direction at the center.
and a main body 11 made of a synthetic resin, the main body 11 being disposed on the upper surface side of the main body 11 so as to be swingable in a vertical direction.
A rocking body 12 made of a synthetic resin having a plate-like holding portion 12a for holding a part of clothes between the holding portion 11b and a top surface of the rocking body 12, and is rotatably mounted on the main body 11; Operating lever 13 made of synthetic resin that is attached to be tiltable
When the operation lever 13 is rotated to the upright position shown in FIG. 22, the holding portion 11b of the main body 11 and the swinging body 12
When the operating lever 13 is turned to the tilted position shown in FIG. 21, the space between the holding portion 11b of the main body 11 and the holding portion 12a of the rocking body 12 is closed. Have been.

In FIGS. 20 and 21, reference numeral 11d denotes a non-slip projection formed on the upper surface of the holding portion 11b of the main body 11, reference numeral 11e denotes a bearing groove formed on the inner side surface of the central side wall of the main body 11, and 12b. Is a non-slip projection formed on the lower surface of the holding portion 12a of the rocking body 12, and 13a is a support shaft formed on the rear end side of the operation lever 13 and rotatably fitted in the bearing groove 11e of the main body 11. .

When the operating lever 13 is turned to the tilting position shown in FIG. 21 in the clip structure of the stopper 10, the swinging body 12 is moved by the rear end of the operating lever 13.
The rear end side is pressed against the main body 11 against the elastic force of the elastic piece 11 c of the main body 11, and the rocking body 12 assumes a holding position that is substantially parallel to the main body 11. As a result, the stopper 10 is fixed to the holding portion 11b of the main body 11 and the swinging body 1
In this state, the space between the two holding portions 12a is closed, and a part of the clothes is held. Also, the operation lever 13 is
When the pivoting operation is performed to the upright position shown in FIG. 2, the pressing state of the rocking body 12 by the rear end portion of the operation lever 13 is released, and the rocking body 12 is urged upward by the elastic force of the elastic piece 11c to the main body 11.

By the way, the stopper 10 has a structure in which the elastic piece 11c of the main body 11 presses and biases a portion of the rocking body 12 which is separated from the pivot (the support shaft 13a) of the operating lever 13. Therefore, unless the deformation amount of the elastic piece 11c is set to be large, the swinging body 12 cannot be reliably and satisfactorily pressed to the open position.
However, when the amount of deformation of the elastic piece 11c is set to be large, if the elastic piece 11c is elastically deformed many times,
The elastic force gradually disappears, and the rocking body 12 cannot be pressed and urged to the open position. As a result, in the conventional stopper 10, even if the operation lever 13 is rotated to the upright position, the elastic piece 11c cannot press and urge the rocking body 12 to the open position. The distance between the holding portion 11b and the holding portion 12a of the oscillating body 12 is inevitably reduced, which causes a problem that it becomes difficult to partially interpose the clothes between the holding portions 11b and 12a. In particular, the main body 11
Since the elastic piece 11c is formed in a narrow and thin plate shape, the above problem is further promoted.

The present invention has been made in view of such problems, and an object of the present invention is to provide a stopper which can reliably and satisfactorily urge a rocking body to an open position. .

[0008]

In order to achieve the above object, a stopper according to the present invention comprises a plate-like holding portion and an elastically deformable plate-like elastic piece. It is attached to the main body made of synthetic resin, which is attached to the main body so as to be able to swing up and down, and is urged upward by an elastic piece of the main body and a holding position for holding a part of the clothes between the holding portions of the main body. When the operating lever is tilted with respect to the main body, the oscillating body includes an oscillating body that can take an open position for releasing clothes, and an operation lever that is rotatably and tiltably attached to the main body and oscillates the oscillating body. When the rocking body is pressed against the body by the operating lever against the elastic force of the elastic piece of the main body to take the holding position, and when the operating lever is in the upright state with respect to the main body, the rocking body is pressed by the operating lever. Is released and the oscillator is A stopper configured to take an open position by virtue of a force, wherein the elastic piece is provided on the main body so as to be located near a rotation center of the rocking body; The moving body is characterized in that a projection pressed by an elastic piece of the main body is provided so that the swinging body takes an open position.
