Description

FIELD OF THE INVENTION

The present invention relates to hair clips, and particularly to a hair clip which has improved the defect in the prior art dock-mouth like hair clip; the hair can be clamped firmly in the hair clip without sliding out from the hair clip.

BACKGROUND OF THE INVENTION

With referring to FIG. 8, the prior art hair clip 1 like a mouth of a dock is illustrated. The hair clip 1 has an upper clip body 11 and a lower clip body 12. Rear ends of the upper clip body 11 and the lower clip body 12 are clamped together by a pivotal shaft 13. A tension spring 14 is installed to the pivotal shaft 13. The tension spring 14 applies an elastic force to give a pressure to the front ends of the upper clip body 11 and the lower clip body 12 so that the two clip bodies are closed. When a force is applied to the rear ends of the upper clip body 11 and the lower clip body 12, the front ends of the hair clip 1 will open so as to form a clamping space between the upper clip body 11 and the lower clip body 12. An inner surface of the upper clip body 11 is distributed with a plurality of teeth 111 for increasing the clamping force of the hair clip 1.

The prior art dock-mouth like hair clip 1 has a simple structure and is used on the hair of the user so as to have the effect of decoration. However the prior art hair clip 1 causes that the hair clamped therein will slide out and is unstable. It is often that after used for a time period, the clip will tilt to one side and cannot be retained at an original position so that the clip must be repositioned.

Thus, the prior art clip has the above mentioned defects necessary to be improved.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

Referring to FIGS. 1 and 2, the hair clip 2 of first preferred embodiment of the present invention is illustrated. The hair clip 2 of the present invention has a clip body 11 and another clip body 12. An auxiliary device 3 is installed between the upper clip body 21 and lower clip body 22. An operating end 211 at one end of the upper clip body 21 and an operating end 221 at one end of the lower clip body 22 are combined by a pivotal shaft 23. Another end of the upper clip body 21 is formed as a clamping end 212 and another end of the lower clip body 22 is formed as a clamping end 222. The pivotal shaft 23 is installed with a tension spring 24 for applying elastic forces to the clamping end 212 of the upper clip body 21 and the clamping end 222 of the lower clip body 22 so that the clamping end 212 and the clamping end 222 move to the close directions.

In the embodiment, the upper clip body 21 has a U shape cross section and has two downward extending lateral walls 213. Each lateral wall 213 has a long guide hole 214 near the operating end 211. Each lateral wall 213 has a pivotal point 215 near the clamping end 212. In this embodiment, each pivotal point 215 is formed by two holes at two opposite sides. However other structures are permissible, for example two rods at two opposite sides. The lower clip body 22 has an approximate cambered shape and a middle section thereof along a longitudinal direction thereof has a slot 223.

The main feature of the present invention is the auxiliary device 3 of the hair clip 2. The auxiliary device 3 includes a clamping unit 31 which is connected to at least one actuating rod 32. The clamping unit 31 has a front end 314, a rear end 315 and a pivotal portion 313. In this embodiment, the pivotal portion 313 is formed by two posts which are formed at a middle section of the clamping unit 31. The two pots are insertable into the two holes 215 at two lateral walls 213 of the upper clip body 21 so that the clamping unit 31 is swingable along the pivotal portion 313 as shown in FIGS. 3 and 4.

In this embodiment, the clamping unit 31 is a crank which is formed by a front arm 311 and a rear arm 312. The pivotal portion 313 is at the connection of the front arm 311 and the rear arm 312 so that when the clamping unit 31 swings, the moving direction of the front arm 311 and rear arm 312 are opposite. That is, when the rear arm 312 moves upwards, the front arm 311 swings downwards. In this embodiment, the front arm 311 is installed with teeth portion 316.

In this embodiment, when the front arm 311 of the clamping unit 31 swings upwards, it will contact the upper clip body 21, as shown in FIG. 3 and the front end 314 of the clamping unit 31 slightly protrudes from the clamping end 212 of the upper clip body 21. When the front arm 311 of the clamping unit 31 swings downwards, the front arm 311 will contact the clamping end 222 of the lower clip body 22, as shown in FIG. 4.

The actuating rod 32 has a first end 321 connected to the clamping unit 31 and a second end 322 connected to the upper clip body 21. In this embodiment, the first end 321 has a through hole 323. The rear end 315 of the clamping unit 31 has a rod 324. Two sides of the rod 324 are insertable into the guide holes 214 at two lateral walls 213 of the upper clip body 21 so that the second end 322 of the actuating rod 32 are movable within the guide holes 214.

Referring to FIG. 3, the open state of the hair clip 2 of the present invention is illustrated. When a force is applied to the operating end 211 of the upper clip body 21 and the operating end 221 of the lower clip body 22, the clamping end 212 and clamping end 222 of the hair clip 2 will open so that the rod 324 at the rear end of the actuating rod 32 move toward a front end of the guide hole 214 and is buckled and positioned therein. Because the first end 321 of the actuating rod 32 pulls the rear end 315 of the clamping unit 31, the front end 314 of the clamping unit 31 swings upwards so that a clamping space is defined between the upper clip body 21 and lower clip body 22.

The use of the hair clip 2 of the present invention is illustrated in FIGS. 4 and 5 of the present invention. When the user pulls the hair 4 upwards, the upper clip body 21 and lower clip body 22 of the hair clip 2 will open and clamp the hair 4. Because the hair 4 extrudes the pivotal connection of the clamping unit 31 and the actuating rod 32 so as to push forwards the rear arm 312 of the clamping unit 31 and the actuating rod 32. Thus, the rod 324 at the rear end of the actuating rod 32 will move toward the rear side of the guide hole 214. The front arm 311 of the clamping unit 31 swings downwards to contact the clamping end 222 of the lower clip body 22 so as to seal the hair 4 in the clamping space 25. Thus the hair 4 will not slide out of the upper clip body 21 and lower clip body 22.

With referring to FIG. 6, the close operation of the hair clip 2 of the present invention is illustrated. When the upper clip body 21 and lower clip body 22 at FIG. 3 are closed by the elastic force of the tension spring 24, the lower clip body 22 is pushed by the elastic force to eject the front end 314 of the clamping unit 31 so that the clamping unit 31 ejects the upper clip body 21 to have the state illustrated in FIG. 7. At this state, the front arm 311 of the clamping unit 31 adheres upon the upper clip body 21. The rear arm 312 of the clamping unit 31 and the actuating rod 32 swings downwards together to protrude out of the slot 223 of the lower clip body 22 (referring to FIG. 2).

The hair clip 2 according to the present invention, by the auxiliary device 3, the upper clip body 21 and lower clip body 22 clamp the hair. The front end 314 of the clamping unit 31 swings downwards to clamp with the lower clip body 22. Thereby the hair clamping in the hair clip 2 will not slide out of the upper clip body 21 and lower clip body 22. Thus, the present invention provides a steady clamping effect.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
