[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a case in which a carrying strap for carrying a portable device such as a mobile phone or a pager is supported on a garment or the like, or a document clip as a stationery, a memo clip or a clothesline. The present invention relates to a synthetic resin clip to be used as a clip.

[0002]

2. Description of the Related Art Conventionally, when carrying portable goods such as a mobile phone and a pager in a clothes pocket or the like,
A part of the clothes is clamped by an opening / closing clip attached to one end of the carrying strap to prevent the portable articles from accidentally dropping when the user is lowered.

[0003] The clip provided for this purpose has an operability that can be easily attached and detached by a simple operation, while maintaining a holding force capable of securely holding portable articles on clothes and the like, and maintaining the holding force for a long period of time. It is required that the outer shape of the clothes is small and that the decorations have excellent quality because they are exposed to the outer surface of the clothes.

More specifically, the inclined sub-substrate is connected by a connecting pin so that the front end portion is opened and closed at a position near the rear end of the opposing surface of the decorative substrate having a decorative pattern or the like on its surface. A spring is elastically mounted on the connecting pin so as to sandwich the object between the tip portions, so that the tip of the inclined sub-board is elastically connected to and separated from the tip of the decorative board, and is opened and closed. In addition to a metal clip, as disclosed in Japanese Patent Application Laid-Open No. 7-27327, a foldable elastic band is extended and formed on the top of a synthetic resin clip main body having a pair of shaft support pieces protruding from both side edges. A movable piece corresponding to the clip body from the band and having a resilient band, or a resilient band and a resilient metal piece whose end is given an elasticity that jumps up from the end of the clip body, is formed. By pressing near the part passing through the inside of one pair Forming an inclined portion for joining the portion to the end of the clip body, and pressing the inclined portion with a pushing leg by rotation to join the end to the end of the clip body. 2. Description of the Related Art There is known a clip made of synthetic resin, which is supported by a clip.

[0005]

However, in the above-mentioned known metal clips, the metal ends may damage the cloth of clothes, the fingers of the user, and the like. Depending on the degree of rust, the decorative board may become unusable depending on the degree of the function of forming the metal material, and the decorativeness of the decorative board is uniform, and there is a limit in responding to diversification of tastes.

On the other hand, the above-mentioned known synthetic resin clips are formed by utilizing the molding function unique to the synthetic resin material.
Although it is configured using the elasticity of the material, the elastic band extended from the clip body is folded back on the clip body to give deformation, thereby giving elasticity to the movable piece continuous to the elastic band, When the clothes and the like are held in the state of being held from the open state of the movable piece, a large bending stress acts on the bent portion of the elastic band, and not only the elasticity is impaired due to the settling of the bent portion, but also it is repeatedly opened and closed in a long-term use. In this case, the deterioration due to fatigue progresses, and the shaft of the synthetic resin pressing piece that is supported by the bent portion and the pair of shaft supports is broken, causing a problem with durability such as early loss of the gripping function. There is. To cope with this, if the thickness of the member is increased in order to obtain a sufficient strength, the shape of the component becomes complicated, so that the whole becomes bulky, resulting in a bad appearance.

Further, since the shape of the component parts is complicated, it takes a lot of time to manufacture a molding die, which leads to an increase in the cost of the mold. If the pressing piece is carelessly raised during use, the lock is released and the movable piece remains open, resulting in an inadvertent drop of the portable article. However, there are problems to be solved in these respects.

Therefore, the present invention is constructed by utilizing the elasticity of the synthetic resin material, has the durability to maintain the holding force for a long time, and utilizes the molding function of the synthetic resin. It is an object of the present invention to provide an inexpensive synthetic resin clip that has a decorative property not found in conventional products and has a simple structure that reduces molding and manufacturing costs and assembly costs.

[0009]

According to the present invention, there is provided a synthetic resin clip according to the present invention, which comprises an operating side sub-board in which a hook leg bent in a hook shape in the direction of a biting portion is integrally formed upright on an inner surface. A locking hole into which the locking leg is inserted and a through hole for passing a strap, and a locking portion on an outer surface side of the locking hole near the grip portion and an inner surface of the locking hole. A substrate having support projections erected on a side edge thereof, a locking leg of the sub-substrate being inserted into a locking hole of the substrate to lock its tip to the locking portion, and a top of the support projection of the substrate. The above-mentioned problem is solved by means for opening and closing with the fulcrum as a fulcrum and being connected so that a biting force is urged to the biting portion by the elasticity of the locking leg.
