DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to specific examples shown in the accompanying drawings.

FIG. 1 shows a metal clip 1 to be handled by the present invention and a basic form of a detachable device 2 according to the present invention. The metal clip 1 is formed by bending a substantially rectangular metal plate (suitable for a spring material) at an intermediate portion thereof, and a resilient force in a direction of approaching both ends facing each other always acts. It is formed as follows. Also,
In order to prevent damage to the held object held between the opposing end portions, outwardly curved portions 1a are formed at both end edges thereof.

On the other hand, as shown in FIG. 2, the attachment / detachment tool 2 includes a pair of arms 3, a connecting piece 4 for connecting the arms 3 at an intermediate portion thereof, and a metal clip 1 on the side ( A clip receiving portion 5 defined between the connecting piece 4 and one end of each of the arms 3 so that the clip receiving portion 5 can be inserted from the direction indicated by an arrow in FIG.
And an engagement claw 6 formed at one end of each arm 3 so as to be able to engage with each warped portion 1a of the metal clip 1. The other end of each arm 3 functions as a gripper 2a, and one end of each arm 3 is an operating portion 2b for attaching or detaching the metal clip 1 to or from the object to be clamped.
Function as Note that the attachment / detachment device 2 is entirely integrally formed of a synthetic resin material, and is formed by injection molding using a mold having a surface parallel to the side surface as a parting surface. It can be formed by cutting what is extruded in the direction of the arrow into a desired width.

For example, a sandwiched object A in which a plurality of papers are stacked
To attach the metal clip 1 to the clip 1, first, the metal clip 1 is inserted into the clip receiving portion 5 of the attachment / detachment device 2 from the side (in the direction of the arrow in FIG. 1). At this time, each warped portion 1a of the metal clip 1 is engaged with the engaging claw 6 of the attachment / detachment device 2 (see FIG. 3A).

Next, the grip portion 2a is firmly gripped so that the other ends of the arms 3 are close to each other, and the operating portion 2b side is expanded, whereby the metal clip 1 is expanded (FIG. 3). -B). Then, the gripping force applied to the gripping portion 2a in a state where the edge of the held object A is inserted inside the metal clip 1 is loosened. Then, the object to be clamped A is clamped by the elasticity of the metal clip 1, so that the detachable device 2 remains in that state.
Is moved to the side, only the metal clip 1 is left attached to the edge of the held object A (see FIG. 3D).

On the other hand, to remove the metal clip 1 from the object A to be clamped, the detachable device 2 is brought close to the metal clip 1 attached to the edge of the object A from the side, and the clip receiving portion is removed. 5 allows the metal clip 1 to be received. From this state, by firmly gripping the grip portion 2a, the operating portion 2
The metal clip 1 may be expanded together with b (in a state similar to that in FIG. 3C), and may be removed from the held object A as it is.

Now, in the above-mentioned attachment / detachment device 2, the clip receiving portion 5 is defined by the connecting piece 4, and the metal clip 1 not matching the size of the clip receiving portion 5 cannot be handled. Therefore, a configuration of the attachment / detachment device 20 compatible with a plurality of sizes will be described below with reference to FIGS. Parts having the same functions as those in the above basic form are denoted by the same reference numerals as those in FIGS.

In the attachment / detachment device 20, a flat plate-like guide plate 7 formed integrally with the connecting piece 4 extends between the gripping portions 2a of the pair of arms 3. A slide member 8 slides on the guide plate 7.

The slide member 8 is integrally formed of a synthetic resin material, and has a groove 9 which engages with each side end of the guide plate 7.
And a connecting portion 11 for connecting one end of each of the side portions 10a and 10b to each other. The connecting portion 11 is attached to the guide plate 7 so as to straddle the connecting piece 4. And one side part 10a
Has a suitable length of slit 12 provided from one end side.
Thereby, the flexible portion 13 is formed. This flexible part 13
Are formed with three notches 14 in the shape of a saw blade. These notches 14 are adapted to engage with projections 15 formed on the side end faces of the base of the guide plate 7 with respect to the connecting piece 4. The number of notches 14 is determined according to the type of the target metal clip,
It is not limited to the above.

On the other end of the other side portion 10b, a stopper piece 17 is formed which can be engaged with a projection 16 having a wedge-shaped cross section formed on the guide plate 7. Thus, the slide member 8 is prevented from coming off from the guide plate 7.

On the inner surface of the other end of the pair of arms 3,
Inward projections 18 are formed respectively. A depression 19 having a concave shape when viewed from the side is formed at a position corresponding to the projection 18 on the slide member 8.

When the side surface on the other end side of the slide member 8 is strongly gripped, the free end of the flexible portion 13 bends and the notch 14
Deviate from 5. When the slide member 8 is slid in this state and the gripping force is loosened, the slide member 8 is positioned at a position where the notch 14 engages with the projection 15. Thus, the position of the slide member 8 can be adjusted in three stages. By changing this position, the depth dimension (S, M, and L dimensions in FIG. 4) of the clip receiving portion 5 changes in three stages. In this case, it corresponds to three types of metal clips having different sizes. You can do it.

When the pair of arms 3 is strongly gripped, the distance between the projections 18 provided on the inner surfaces on the other ends of both arms 3 becomes narrow. Here, since the projection 18 corresponds to the depression 19, the tilting range of the arm 3 is limited according to the shape of the depression 19. The correspondence between the projection 18 and the depression 19 is as follows.
It changes according to the position of the slide member 8, and when the state shown in the drawing, that is, when the amount of protrusion of the slide member 8 into the clip receiving portion 5 is the minimum, the protrusion 19 is formed between the front and back surfaces of the slide member 8 at a position where the depression 19 has penetrated. 18 correspond.
Therefore, the maximum opening amount on the side of the operating portion 2b increases. Conversely, when the amount of protrusion of the slide member 8 into the clip receiving portion 5 corresponding to the smallest clip is maximized, the depression 1
The projection 18 corresponds to a part deviating from the part 9. In this state, since the maximum opening amount on the side of the operating portion 2b is small, it is possible to prevent a small clip from being forcibly opened widely and causing permanent distortion.

In the above description, an example in which the pair of arms 3 and the connecting piece 4 are integrally formed of a synthetic resin material has been described. In this case, separate arms are rotatably assembled with each other in accordance with manufacturing convenience. May be formed. In the above example, the elastic force of the connecting piece 4 is used to maintain the one end side of the attachment / detachment device 2 (20) closed without applying an external force. An auxiliary spring may be provided on the 2a side. Further, according to the above configuration, since the attaching / detaching device 2 (20) does not restrict the lateral position of the metal clip 1, the degree of freedom in the width dimension of the metal clip 1 to be handled is high.

[0024]

As is apparent from the above description, according to the metal clip attaching / detaching tool according to the present invention, a pair of arms are provided at the mouth of the metal clip by utilizing the characteristic of the shape of the metal clip in a state of receiving the metal clip. The ends of the metal clips can be engaged with each other and the engagement ends of the arms with the metal clips can be separated from each other by leverage using the connecting portion of the arms as a fulcrum. The metal clip can be easily attached to and detached from an object. Moreover, since the depth of the clip receiving portion can be easily changed, metal clips of different sizes can be handled by one device, and the handling of the detachable device for this kind of metal clip is improved. A great effect can be achieved.
