Hair Clip

Abstract

A hair clip includes a lower clip piece having a lower clamping portion, a lower pressing portion, and a lower pivotal portion. An upper clip piece includes an upper clamping portion, an upper pressing portion, and a front pivotal portion. A first elastic coupling device provides a clamping force between the lower and upper clamping portions. A movable clip piece is disposed above the lower clip piece and includes an intermediate pivotal portion and a lower abutting portion behind the intermediate pivotal portion and aligned with the lower clamping portion. The movable clip piece includes a rear abutting portion and a front bent portion bending downwardly and located in front of front ends of the lower and upper clip pieces. A second elastic coupling device abuts the rear abutting portion against an upper side of the upper clip piece when the hair clip does not clamp hair.

DETAILED DESCRIPTION OF THE INVENTION

[0020] With reference to FIGS. 1-4, a hair clip of an embodiment according to the present invention comprises a lower clip piece 1, an upper clip piece 2, a first elastic coupling device 3, a movable clip piece 4, and a second elastic coupling device 5. The lower clip piece 1 includes a front end having a lower clamping portion 11 and a rear end having a lower pressing portion 12 and a lower pivotal portion 13. The lower clamping portion 11 includes two lower claws 111. The lower pivotal portion 13 is located above the lower pressing portion 12. The lower pivotal portion 13 includes two lower lugs 131 parallel to each other. Each of the two lower lugs 131 has a pivotal hole 132.

[0021] The upper clip piece 2 is disposed above the lower clip piece 1 and has a rear end pivotably connected to the lower clip piece 1. The upper clip piece 2 includes a front end having an upper clamping portion 21. The rear end of the upper clip piece 2 has an upper pressing portion 22 and an upper pivotal portion 23. The upper clamping portion 21 includes an upper bent portion 211 located above intermediate portions of the two lower claws 111 and bending upwardly. The upper pressing portion 22 is aligned with the lower pressing portion 12. The upper pivotal portion 23 is located below the upper pressing portion 22 and includes two upper lugs 231 parallel to each other. Each of the two upper lugs 231 has a pivotal hole 232. The upper clip piece 2 further includes a front pivotal portion 24 at a front end of the upper clamping portion 21. The front pivotal portion 24 includes two front lugs 241 parallel to each other. Each of the two front lugs 241 has a pivotal hole 242. The upper clip piece 2 further includes a top portion having coupling groove 25 behind the upper bent portion 211.

[0022] The first elastic coupling device 3 is configured to provide elastic coupling between the lower pivotal portion 13 of the lower clip piece 1 and the upper pivotal portion 23 of the upper clip piece 2. The first elastic coupling device 3 includes a first pin 31 and a first torsional spring 32. The first pin 31 extends through the pivotal holes 132, 232 of the two lower lugs 131 and the two upper lugs 231 and extends through a coil portion of the first torsion spring 32 to thereby pivotably connect the lower and upper clip pieces 1 and 2. Two ends of the first torsion spring 32 abut against the lower and upper clip pieces 1 and 2 to provide the lower and upper clip pieces 1 and 2 with a clamping force.

[0023] The movable clip piece 4 is disposed above the lower clip piece 1 and includes three movable claws 41 spaced from each other. The middle movable claw 41a is aligned with the upper clamping portion 21 of the upper clip piece 2. One of the two lower claws 111 is located between the middle movable claw 41a and one of the remaining two movable claws 41b. The other of the two lower claws 111 is located between the middle movable claw 41a and the other of the remaining two movable claws 41b. The middle movable claw 41a includes a slot 411 through which the upper bent portion 211 of the upper clamping portion 21 extends. The middle movable claw 41a includes an intermediate pivotal portion 42 at an intermediate, lower portion thereof for pivotal connection with the front pivotal portion 24 of the upper clip piece 2. The intermediate pivotal portion 42 of the movable clip piece 4 includes two intermediate lugs 421 each having a pivotal hole 422. The movable clip piece 4 includes a lower abutting portion 43 behind the intermediate pivotal portion 42. The lower abutting portion 43 extends downwardly and is aligned with the lower clamping portion 11. The movable clip piece 4 includes a front bent portion 44 bending downwardly and located in front of the front ends of the lower and upper clip pieces 1 and 2. The movable clip piece 4 further includes a rear end having a rear abutting portion 45.

[0024] The second elastic coupling device 5 is configured to provide elastic coupling between the intermediate pivotal portion 42 of the movable clip piece 4 and the front pivotal portion 24 of the upper clip piece 2. The second elastic coupling device 5 includes a second pin 51 and a second torsional spring 52. The second pin 51 extends through the pivotal holes 422, 242 of the two intermediate lugs 421 and the two front lugs 241 and extends through a coil portion of the second torsion spring 52 to thereby pivotably connect the movable clip piece 4 and the upper clip piece 2. Two ends of the second torsion spring 52 abut against the movable clip piece 4 and the upper clip piece 2. The rear abutting portion 45 of the movable clip piece 4 is positioned in the coupling groove 25 when the hair clip does not clamp hair.

[0025] With reference to FIG. 5, the lower and upper pressing portions 12 and 22 of the lower and upper clip pieces 1 and 2 can be pressed open, and a hair clamping portion 6 is formed between the lower claws 111 and both the upper bent portion 211 of the upper clip piece 2 and the movable claws 41. When hair 7 received in the hair clamping portion 6 abuts against the lower abutting portion 43 of the movable clip piece 4, the movable clip piece 4 pivots relative to the upper clip piece 2, and the rear abutting portion 45 disengages from the coupling groove 25 and moves upwardly. The lower side of the upper bent portion 211 of the upper clip piece 2 can receive the hair 7 to increase the amount of hair received. Furthermore, the front bent portion 44 of the movable clip piece 4 can pivot downward and rearward, permitting the hair 7 at the front end of the hair clamping portion 6 can be enveloped by the front bent portion 44 and the lower clamping portion 11, avoiding disengagement of the hair 7 from the hair clamping portion 6.

[0026] When the movable claws 41 do not clamp hair, the rear abutting portion 45 is positioned in the coupling groove 25 of the upper clip piece 2, providing improved assembly stability. The movable claws 41 are essentially disposed above the upper clip piece 2, such that the hair 7 will not enter between the movable clip piece 4 and the upper clip piece 2. Thus, the hair clip according to the present invention does not require the conventional guide loop. Furthermore, pivotal movement of the movable clip piece 4 is sufficient to cover the hair 7 by the front bent portion 44, providing improved movement stability. Furthermore, the arrangement of the upper bent portion 211 of the upper clip piece 2 and the slot 411 of the movable clip piece 4 permits the rear abutting portion 45 to be positioned in the coupling groove 25 when the hair clip does not clamp hair, and the upper bent portion 211 permits reception of more hair during hair clamping, improving utility of the hair clip. Furthermore, the two lower claws 111, the upper clamping portion 21, and the three movable claws 41 provide a large hair-clamping area, further improving hair clamping stability.

[0027] Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
