DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip having a locking function, and more particularly, to a clip provided with a projection for piercing and locking a cardboard box or a piece of cloth.

[0002]

Heretofore, as a means for temporarily locking the clip, a method has been employed in which a ring-shaped hole provided in the clip is hooked on a projection provided on the portion to be locked. . In addition, a method of using a magnet or a suction cup or forming a double clip has been adopted.

However, there is no suitable method for temporarily locking the clip to a cardboard box or a piece of cloth. For example, in the clip 10 shown in FIG.
This was very inconvenient because the weight was temporarily locked by placing a weight on it. In particular, in the task of sorting cardboard boxes and fabric cloth, it is necessary to temporarily hold the slip displaying the contents between clips in the process until the official label is attached. The method was very poor in workability and an improvement was desired.

The inventor of the present invention has intensively studied a clip having a locking function capable of temporarily locking a clip to a cardboard box, a piece of cloth, or the like, and as a result, the present invention has been accomplished.

[0005]

The present invention takes the following means to solve the above-mentioned problems. That is, the gist of the present invention is to provide a clip provided with a sharp-pointed projection for piercing a locked surface and locking the clip.

Further, the tip of the projection is directed toward the holding portion so as to be substantially parallel to the central axis of the clip. Further, a part of a metal plate constituting the clip is cut, and the projection is formed by the cut portion. It is to form.

[0007]

Next, an embodiment of a clip according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a clip 10 according to the present invention. Two main structural members 12, 12 formed from a metal plate are connected by a shaft 14, and a coil spring 15 is wound around the shaft 14. Functionally, the holding unit 16 and the holding unit 16 based on the elastic force of the spring 15
And an operation unit 18 that operates the opening and closing of the device by acupressure.
A projection 20 formed by cutting a part of the holding portion 16 and bending the cut portion is provided.

FIG. 2 further explains the clip shown in FIG. 1. The tip of the projection 20 is sharply pointed so as to pierce the surface to be locked. Also, the protrusion 20
Is bent in an L-shape, and its tip is directed toward the holding portion 16 and is substantially parallel to the central axis 26 in the direction connecting the operating portion 18 and the holding portion 16.

FIGS. 3 (a), 3 (b) and 4 illustrate a method of locking the clip 10 of this embodiment to a cardboard box 22. FIG. First, after inserting the slip 23 and the like, FIG.
As shown in FIG. 3A, the projection 20 is pierced into the side surface of the cardboard box 22 or the upper end corner of the cardboard box 22 to be locked. Protrusion 20
Is relatively thin and thin, so that it does not penetrate the cardboard and damage the contents and the like inside. Further, since only a small hole remains after the protrusion 20 is removed, there is no possibility that the appearance and durability of the cardboard box 22 are impaired.

When the lid of the cardboard box 22 is opened, there is no need to pierce the projection 20.
As shown in (c), the projection 20 can be hooked and locked on the upper end of the side wall of the cardboard box 22. At this time, the cardboard is completely intact because the projection 20 is not pierced. Further, since there is no need to pierce the protrusion 20, the clip 10 can be locked by hooking the protrusion 20 on the side wall even in a plastic or iron box or the like.

Similarly, FIG. 5 and FIG.
This is an example in which the clip 10 is locked at the same time. The clip 10 is stably locked by the protrusion 20 pierced on the side surface of the cloth 24, and does not leave any scar after being pulled out. In this example, it is preferable that the projection 20 is formed in a needle shape.

The clip of the present invention is not limited to the above example, and can be obtained by partially modifying various types of clips that are generally used. For example, clips 27 and 28 of the type shown in FIGS. 7 and 8 can be used. In this example, the projection 20 is the main structural member 1
2 is formed by bending the cut portion. Also,
A clip 30 of the type shown in FIG. 9 may be used. In this example, the projection 20 is formed integrally with the main structural member 12 made of plastic. In addition, a clip 32 of the type shown in FIG. 10 can be used. In this example, the projection 20 is formed integrally with the main structural member 12 having a semi-clip shape.

The material of the projection 20 may be the same as that of the main structural member 12 or a different material. It may be formed integrally with the main structural member 12 by press molding or injection molding, or may be formed after being formed in a separate step and then joined. For example, welding,
Bonding methods such as bonding and fitting can be used.

The shape of the projection is not particularly limited as long as the tip is sharp. An appropriate shape is selected according to the material and shape of the place to be locked. For example, a triangular plate-shaped projection 20 as shown in FIG. 11A is suitable for a cardboard or a soft locked surface, and a thin projection 20 as shown in FIG. Suitable. Further, if the projections 20 are wide as shown in FIG. 12C, it is convenient to insert them into the gaps 25 when they are stacked in a box as shown in FIG. Alternatively, as shown in FIG. 13, a projection 2 having a shape in which a narrow part 27 is provided in the middle.
If it is set to 0, there is an effect that it is hard to come off and is more stably locked.

Claim 2 relates to a device for stably locking the clip. The direction of the protrusion 20 according to the present invention may be, for example, a direction perpendicular to the central axis 26 of the clip 10 as shown in FIG. 14A, or a central axis as shown in FIG. Although it may be provided to be inclined with respect to 26, it is not particularly limited, but is preferably substantially parallel to the central axis 26.

4 and 6, since gravity is applied in the direction of the holding portion 16 along the central axis 26 in the normal usage as shown in FIGS. It is harder to slip out and is more stable. 3 and 4
As is apparent from the above, when the projections 20 are provided substantially parallel to the central axis 26 when the cardboard box 22 is locked, the projections 20 stop inside the cardboard material and the cardboard box 22
Does not penetrate through the cardboard box 22, so that the contents inside the cardboard box 22 are not damaged. Further, since the pointed tip of the protruding portion faces in the opposite direction to the operation unit 18, the hand is safe without sticking.

If the projections 20 are formed of a metal plate having an appropriate thickness, the angle of the projections 20 can be freely changed as shown in FIG. 15, for example. It is a very convenient clip that can be used in a wide range of applications.

A third aspect of the present invention relates to a clip which is easy to use and easy to manufacture, in which a part of a main structural member made of a metal plate is cut, and the cut portion is raised to form a projection. In the locking method of the present invention, in which the projection is pierced into the locking surface, a thin projection is preferable because it is easy to pierce and no scar is left on the trace that has been removed, but plastic cannot be used as a thin projection because it is easily broken.

In a clip made of a metal plate, a clip with a projection as shown in FIG. 1 or FIG. 7 can be easily manufactured only by punching and pressing.
Even relatively thin or relatively thin projections can be used without breaking or bending. The shape of the cut portion may be cut so as to leave the end portion 17 of the holding portion 16 as shown in FIGS. 1 and 7, or may be cut to the end of the holding portion 16 as shown in FIG. .

In addition, the present invention can be carried out in various modified, modified, and modified forms based on the knowledge of those skilled in the art with regard to the shape and material of the clip, the shape of the projection, and the like, without departing from the spirit of the present invention. Things.

m, and the thickness of the main structural member 12 was 0.8 mm. The center of the clip 10 is 20mm wide and 30m long
Then, the cut portion was bent at a right angle to stand up, and a tip having a height of 5 mm was bent toward the holding portion 16.

Using the clip 10 of the present embodiment, the slip 23 was fixed in the sorting operation of the cardboard box luggage. The slip 23 was sandwiched between the holding portions 16, and the projection 20 was pierced into the upper end corner of the cardboard box to lock the clip 10 to the cardboard box. The clip 10 did not come off during the sorting operation, and the projection was removed and the clip 10 was removed after the sorting operation was completed. The traces from which the protrusions were removed had only slight holes, and the appearance was normal.

Second Embodiment A clip 10 similar to that shown in FIG. 11B was manufactured. The procedure was the same as that of Example 1 except that the protrusion 20 was formed into a strip having a width of 5 mm and the tip was sharpened. Clip 1 of this example
0 could be used particularly conveniently for fabrics.

Third Embodiment A clip 10 similar to that shown in FIG. 11C was manufactured. Example 1 was the same as Example 1 except that the protrusion 20 was formed in a strip shape having a width of 20 mm. The clip 10 of this example was convenient because it could be inserted and locked in the gap between the stacked cardboard boxes.

Fourth Embodiment A clip 10 identical to that of the second embodiment was manufactured except that the projection 20 was oriented in a direction perpendicular to the central axis 26 of the clip 10. The clip 10 of this example was very convenient for piercing and locking a side surface of a cardboard box or a piece of cloth.

Fifth Embodiment A clip 10 similar to that shown in FIG. 1 was produced. It was the same as Example 1 except that the thickness of the projection 20 was 0.3 mm. The clip 10 of this example was very useful because the projection 20 could be bent with a finger and the angle could be freely adjusted according to the application.

Sixth Embodiment A clip 10 similar to that shown in FIG. 8 was produced. A cut having a width of 3 mm was made in a commercially available clip having a width of 30 mm of the holding portion 16 and a steel plate thickness of 0.8 mm, and the cut portion was bent to form a projection.

[0030]

According to the clip of the present invention, since the clip has a sharp-pointed projection, the clip can be locked by piercing a cardboard box or a cloth cloth. In addition, since relatively thin projections can be used, a cardboard box, cloth, and the like of a cloth are not damaged.

Further, by making the direction of the tip of the projection parallel to the center axis of the clip, it is possible to prevent the projection from penetrating the cardboard box or the like and damaging the contents contained therein. In addition, since it becomes difficult to pull out, the stability of locking is improved. Furthermore, since the position of the tip of the projection is separated from the clip operation unit, it is possible to obtain effects such as not damaging a finger or the like.

Further, by cutting a part of the clip made of a metal plate and forming a projection from the cut portion, a thin and strong projection can be easily provided, so that the workability of locking is further improved.
