DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a strap, a suspender end, or the like of a portable device such as a cellular phone, a camera, a key, or the like, or a fastener for clothing, and firmly sandwiches the object to be worn. It concerns a possible synthetic resin clip.

[0002]

2. Description of the Related Art Conventionally, a clip used for a strap or an end of a suspender of a portable device such as a mobile phone, a camera, a key, and the like has to secure a sufficient clamping force from the viewpoint of preventing falling off. In many cases, robust metal parts were used.

However, in recent years, various synthetic resin clips have been used in order to secure safety against fingers and skin, prevent damage to the fabric to be attached, and reduce the cost of raw materials. Has reached.

[0004] In a synthetic resin clip used for such an application, a structure for ensuring a sufficient clamping force is indispensable. 2000-18215, registered utility model 3048611, or patent 2014
No. 106, using a spring member or using spring elasticity by resin and using a cam mechanism of the operation unit together, or a device using only the cam mechanism of the operation unit as disclosed in Japanese Patent No. 2981744. The prior art is known.

[0005]

In the above-mentioned prior arts, all of them are relatively small and can obtain a sufficient clamping force. However, since the operation unit is in an open state before clamping, Since the dimension from the distal end of the operating portion in the open state to the vicinity of the distal end of the holding portion is larger than the narrow width of the clip, and the operating portion itself axially moves in the open state and also has a returning force, The shape when gripping with a finger is unstable and is difficult to grip.

[0006] Then, in order to hold the synthetic resin clip according to the prior art with respect to the object to be mounted, such a small-sized clip which is hard to be picked up is returned with one hand only by the above-mentioned cam mechanism or spring elasticity. Since the pressing operation must be performed against the force, the clamping operation is very inconvenient.

Further, since the operating body and the holding portion are separate from each other, care must be taken to guide the mounting object so that the holding portion is positioned and held at a specific position of the mounting object. Must.

[0008] Therefore, due to such a structural defect, when the synthetic resin clip according to the prior art is clamped, it is difficult to press the operating body in a direction perpendicular to the clip body. Is incorrect, the entire clip is lying down and cannot be pinched, or if the clip slides down from the finger holding the clip, or if the object to be mounted is a thin cloth, the positioning is good. In many cases, the cloth at the pinching position is pinched in a wrinkled state, and the pinching operation cannot be performed simply and reliably in practice.

On the other hand, in a synthetic resin clip,
For example, as in the prior art disclosed in Japanese Patent No. 2014106, it is one of the important issues to reduce the number of parts to reduce the manufacturing cost and simplify the assembling work. Also, it is desirable to ensure sufficient security in solving the various problems described above.

[0010] The present invention has been made in view of the above circumstances, to improve the operability at the time of clipping of the clip, to prevent the clip from falling down at the time of clipping, to prevent defects such as slipping from the finger, and the like. It is an object of the present invention to provide an inexpensive synthetic resin clip which can be securely and easily clamped and is easy to assemble.

[0011]

According to the present invention, there is provided a clip base having at least a holding plate, and a holding piece axially moving with respect to the clip base, wherein the clip base comprises a holding plate and a contact plate. One end is connected vertically and the other end is connected to each other, and the other end is formed as a bifurcated structure opened at an interval for inserting an object to be mounted. A shaft mechanism part of the piece is formed in the width direction of the clip base, and the abutment plate has a claw through hole for allowing the locking claw of the holding piece to pass therethrough and a contact part for restricting rotation of the holding piece. And having a configuration in which an engagement end portion corresponding to the engagement portion of the holding piece is formed at the tip, and the holding piece projects a locking claw at a position corresponding to the claw through hole, An engaging portion that engages with the engaging end of the contact plate is formed near the free end, and The distance to the axial center of the shaft mechanism portion,
As a dimension not more than the distance from the engagement end to the shaft center of the shaft mechanism, a strong engagement between the engagement part and the engagement end is ensured, and the engagement part of the sandwiching piece is formed of the contact plate. A synthetic resin characterized in that the engaging claw passes through a claw through hole by being engaged with the engaging end portion, and has a clamping function by the clamping plate and the retaining claw in the clip base. The clip made is a means for solving the problem.

[0012]

According to the present invention, the distance from the engaging portion of the holding piece to the shaft center of the shaft mechanism is smaller than the distance from the engaging end of the contact plate to the shaft center of the shaft mechanism. As a result, a firm engagement between the engaging portion and the engaging end portion is ensured, and the engaging portion of the holding piece is engaged with the engaging end portion of the abutting plate, so that the locking claw can be threaded. Passing through the hole, the clipping base and the locking claw of the clip base have a pinching function, so that operations such as tilting the operation unit against the return force as in the prior art can be performed. There is no need to perform this operation, simply and firmly by inserting the mounting object into the holding portion and holding the free ends of both the holding piece and the clip base in the mutual contact position with fingers to engage. The synthetic resin clip can be attached.

The clip base has a holding plate and an abutment plate arranged vertically and connecting one end to each other, and the distance between the holding plate and the abutment plate is set to a distance allowing insertion of an object to be mounted. The two-pronged structure having the sandwiching portion described above, the inserting position can be substantially determined only by inserting the mounting object into the sandwiching portion having a certain dimension, and the mounting operation can be further facilitated.

When the object to be mounted is inserted into the holding portion, the holding piece is gripped in contact with the abutting plate, and the holding piece has no return force. The object to be mounted can be very easily guided and inserted into the holding portion, and it is possible to reliably prevent the clip from falling down or the clip from sliding down from the finger during the holding operation.

When the contact plate is formed with a groove for fitting the holding piece, the contact plate and the holding piece are engaged with each other at the time of mounting or when not in use. The synthetic resin clip can be made more compact.

Further, when the hanging string attaching means is integrally formed with either the clip base or the holding piece, a synthetic resin clip can be constituted only by the two members of the clip base and the holding piece. The production cost and the assembling work can be significantly simplified.

Further, a bearing portion corresponding to the shaft portion of the holding piece is formed inside the abutting plate by penetrating the holding plate at two places by a molding pin from the bottom side of the holding plate in the clip base. In addition, the contact plate, for the purpose of attaching the shaft portion of the holding piece to the clip base,
A mounting hole for passing the shaft-side end of the holding piece through the bearing portion of the clip base is provided, and the holding piece has a shaft formed at one end thereof. Can be inserted into the bearing portion of the clip base through the mounting hole, and a clip made of synthetic resin which is extremely easy to assemble can be provided.
