- A45D 8/24: Hair clasps, i.e. multi-part clasps with pivotal connection of parts at their ends
- A45D: HAIRDRESSING OR SHAVING EQUIPMENT (wigs, toupees or the like A41G3/00, A41G5/00; hairdressers' chairs A47C1/04; hair cutting appliances, razors B26B); EQUIPMENT FOR COSMETICS OR COSMETIC TREATMENTS, e.g. FOR MANICURING OR PEDICURING

## Abstract

A fastener part 6 on one end of a base plate 1 includes clip arms 7 having enough length to deform flexibly to release a clip plate 2 from the base plate 1, and extending from the base plate 1 toward an axis part 3 on the other end of the base plate 1, so that the height of the fastener part 6 from the base plate 1 is low to form a thin and attractive hair clip, which fits comfortably. When the base plate 1 and the clip plate 2 engage each other, the clip plate 2, curving to bulge out toward the base plate 1, presses the base plate 1 and the base plate 1 is formed into a bow shape along the clip plate 2 by its flexibility, so that the plates 1 and 2 contact each other broadly and press strongly against each other to hold hair securely between them.

## Claims

### Claim 1

A hair clip comprising:
a base plate (1);
a clip plate (2) curving to bulge out toward said plate (1) so as to press hair against said base plate (1) and hold hair between said base plate (1) and said clip plate (2) when said base plate (1) and said clip plate (2) engage each other;
an axis part (3) facing said clip plate (2) and being provided on one end of said base plate (1);
a fastner part (6) facing said clip plate (2) and being provided on the other end of said base plate (1),
said fastener part (6) comprising clip arms (7), which have enough length to deform flexibly to release the engagement between said base plate (1) and said lip plate (2), and said clip arms (7) extending from said base plate (1) toward said axis part (3); and
where one end of said clip plate (2) is connected pivotally to said axis part (3), and the other end of said clip plate (2) is snappable into said fastener part (6) to obtain said engagement and releasable from said fastner part (6).

### Claim 2 (depends on 1)

A hair clip according to claim 1, wherein said clip arm (7) extend in an L-shape from said base plate (1) toward said axis part (3).

### Claim 3 (depends on 1)

A hair clip according to claim 1, wherein incisions (13) are cut longitudinally in the center part of said clip plate 2, and a portion between said incisions (13) is lifted and curved in an outward direction from said base plate (1) to form a protuberance (14).

### Claim 4

A hair clip according to claim l, wherein said base plate (1) and said clip plate (2) contact each other so that said base plate (1) and said clip plate (2) maintain a power to spring away each other when said base plate (1) and said clip plate (2) engage each other.

### Claim 5 (depends on 2)

A hair clip according to claim 2, herein said base plate (1) and said clip plate (2) contact each other so that said base plate (1) and said clip plate (2) maintain a power to spring away each other when said base plate (1) and said clip plate (2) engage each other.

### Claim 6 (depends on 3)

A hair clip according to claim 3, herein said base plate (1) and said clip plate (2) contact each other so that said base plate (1) and said clip plate (2) maintain a power to spring away each other when said base plate (1) and said clip plate (2) engage each other.
