Description

[Technical field]

[0001] The present invention relates to a hair clip, and more particularly to a hair clip that allows the range in which the hair clip holds the hair to be adjusted. [Background technology]

[0002] A known general hair clip has two clamps, and the two clamps can be opened to clamp hair. However, the width of the clamps and the range that the clamps can accommodate are fixed, so if it is necessary to clamp a wide range of hair, a hair clip with a wider clamp width must be used. However, if it is necessary to clamp only a small amount of hair, the hair clip will not fit, so the user must prepare various hair clips with different clamp widths, which is inconvenient for use and portability.

[0003] The hair clip disclosed in Patent Document 1 has a plurality of arranged pieces, each of which has a pivot. Furthermore, a connecting piece is installed between each adjacent piece, and both ends of the connecting piece have pivot holes. The pivot shaft on the upper side of one piece is inserted into each of the pivot holes at one end of the connecting piece, and the pivot shaft on the lower side of the other adjacent piece is pivotally attached, so that the distance between each connecting piece and each piece can be adjusted by widening or narrowing it. This allows the range of hair that the hair clip holds to be changed, improving applicability.

[0004] However, since the connecting piece and the body are connected only by the pivot hole and the rotation axis, and there is no angle limit, if too much force is applied to unfold each connecting piece and body, the pivot hole of the connecting piece is likely to shift along the rotation axis of one body, causing the connecting piece and one body to separate. In addition, since the positioning of the connection between the connecting piece and one body is not stable even after adjustment, the width of the hair clip may change.

[0005] In addition, the hair clip in Patent Document 2 has multiple linear expansion parts and linear joint parts, and the relatively long cylinders on the expansion parts are combined with the holes in the joint parts to give the hair clip the ability to expand and contract. However, this hair clip also has the disadvantage that the width of the hair clip is easily changed after adjustment, and the cylinders and holes come off when force is applied to expand it.

[0007] An object of the present invention is to provide a hair clip that allows the range in which it clamps the hair to be adjusted and has good positioning stability. [Means for solving the problem]

[0008] The present invention includes a first clamping piece, a second clamping piece, an elastic member, a plurality of first connecting pieces, and a plurality of second connecting pieces. The first clamping piece and the second clamping piece are symmetrical with respect to a symmetry plane extending in the vertical direction. The first clamping piece has a first clamping portion on the lower side and a first pressing portion on the upper side, and the second clamping piece has a second clamping portion on the lower side and a second pressing portion on the upper side. The first clamping piece is provided with a first pivoting portion, and the second clamping piece is provided with a second pivoting portion so that they can be pivotally attached together. A first positioning portion is provided below the first clamping piece, and a first expansion positioning groove and a first reduction positioning groove are provided in the first positioning portion, and a second positioning portion is provided below the second clamping piece, and a second positioning portion is provided in the second positioning portion, and a second expansion positioning groove and a second reduction positioning groove are provided in the second positioning portion. The elastic member provides a clamping force to the first clamping piece and the second clamping piece. The first connecting piece has a linear shape, and its lower side is pivotally connected to the first clamping piece or the second clamping piece, respectively. The first connecting piece is provided with an upper positioning body, and its lower side is provided with a lower positioning body that can be joined with the first expanded positioning groove or the second expanded positioning groove, or the first reduced positioning groove or the second reduced positioning groove. The second connecting piece has a straight shape and is pivotally connected to the first connecting piece at its upper side. The second connecting piece has a third positioning portion at its upper side, and the third positioning portion has a third expanded positioning groove and a third contracted positioning groove that can be joined to the upper positioning body of the first connecting piece.

[0009] In one embodiment of the present invention, a first pivot shaft is provided on the underside of the first clamping portion at a position corresponding to above the first positioning portions on both the left and right sides of the symmetry plane, and a second pivot shaft is provided on the underside of the second clamping portion at a position corresponding to above the second positioning portions on both the left and right sides. There are four first connecting pieces, and a first pivot hole is provided on the lower side of each first connecting piece at a position corresponding to the upper side of the lower positioning body. The first pivot hole of each first connecting piece is pivotally connected to the first rotating shaft of the first clamping piece or the second rotating shaft of the second clamping piece. A third rotating shaft is provided on the upper side of the first connecting pieces. The number of second connecting pieces is four, and the second connecting pieces are provided with second pivot holes to be pivotally connected to the third rotating shafts of the first connecting pieces. Effect of the Invention

[0010] The hair clip of the present invention can be positioned in the up and down directions by joining the upper positioning body to the third deployment positioning groove, and the lower positioning body to the first deployment positioning groove and the second deployment positioning groove. By ensuring that the deployed width of the hair clip does not change, the hair clip can have good stability.

[0011] The present invention allows the hair clip to be shortened when a relatively small amount of hair needs to be clipped or when the volume of the hair clip needs to be reduced to make it easier to carry. The upper positioning body can be joined to the third reduced positioning groove, and the lower positioning body can be joined to the first reduced positioning groove and the second reduced positioning groove in the up and down directions, respectively, to position the hair clip, ensuring that the width of the hair clip remains unchanged and the shortened state is maintained, thereby providing good stability to the hair clip.

A first positioning part 15 is provided below the first rotating shaft 14 of the first clamping piece 1, and a first expansion positioning groove 151 and a first reduction positioning groove 152 are provided in the first positioning part 15. In addition, a second positioning part 25 is provided below the second rotating shaft 24 of the second clamping piece 2, and a second expansion positioning groove 251 and a second reduction positioning groove 252 are provided in the second positioning part 25.

[0015] The elastic member 3 provides a clamping force to the first clamping piece 1 and the second clamping piece 2.

[0016] The first connecting pieces 4 are four in number and are linear. The lower side of the first connecting pieces 4 is provided with a first pivot hole 41 which is pivotally connected to the first rotating shaft 14 on the left and right sides of the first clamping piece 1 and the second rotating shaft 24 on the left and right sides of the second clamping piece 2, respectively. After assembly, the convex edges 142, 242 at the tops of the first rotating shaft 14 and the second rotating shaft 24 are joined to the edge of the first pivot hole 41, thereby providing good assembly robustness. In this embodiment, the corresponding structures of some of the first connecting pieces 4 located on both the left and right sides have different directions, but are indicated by the same reference numerals in the drawings. The lower side of the first pivot hole 41 is provided with a lower positioning body 42 which can be joined to the first expansion positioning groove 151, the second expansion positioning groove 251 or the first reduction positioning groove 152, the second reduction positioning groove 252. A third rotating shaft 43 is provided on the upper side of the first connecting piece 4, and a notch 431 which is a flexible deformation space is provided on the third rotating shaft 43, and a protruding edge 432 is provided on the top end. An upper positioning body 44 is provided below the third rotating shaft 43, and a first insertion pin 45 which can be inserted into hair is protruded from the lower side of the first connecting piece 4.

[0017] The second connecting piece 5 is four in number and has a linear shape. A curved portion 51 is provided on the upper side of the second connecting piece 5, and the curved portion 51 is provided with a second pivot hole 52 that is pivotally connected to the third rotating shaft 43 of the first connecting piece 4. In this embodiment, the corresponding structures of some of the second connecting pieces 5 located on both the left and right sides have different directions, but are indicated by the same reference numerals in the drawings. After assembly, the convex edge 432 of the third rotating shaft 43 is joined to the top edge of the second pivot hole 52, thereby providing good assembly robustness. In addition, the upper positioning body 44 can be accommodated in the space below the curved portion 51 to reduce the contracted volume of the hair clip. A third positioning portion 53 is provided below the second pivot hole 52, and the third positioning portion 53 has a third expanded positioning groove 531 and a third reduced positioning groove 532 that can be joined to the upper positioning body 44 of the first connecting piece 4. A second insertion pin 54 that can be inserted into hair is protruded from the lower side of the second connecting piece 5.

[0018] In the present invention, the left and right sides of the first clamping piece 1 and the second clamping piece 2 are pivotally attached to the first connecting piece 4. The lower positioning body 42 of the first connecting piece 4 is joined and positioned to the first deployment positioning groove 151 and the second deployment positioning groove 251, and the second connecting piece 5 is pivotally attached to the first connecting piece 4. The upper positioning body 44 of the first connecting piece 4 is joined and positioned to the third deployment positioning groove 531 of the second connecting piece 5, so that the hair clip can have a relatively large deployment range that can hold more hair. Furthermore, the first insertion pin 45 and the second insertion pin 54 are inserted into the hair, so that the stability of holding the hair can be improved. In addition, when the hair clip is deployed, the upper positioning body 44 can be joined and positioned to the third deployment positioning groove 531, and the lower positioning body 42 can be joined and positioned to the first deployment positioning groove 151 and the second deployment positioning groove 251 in the up and down directions, respectively, at the same time, and the width of the hair clip is ensured not to change, so that the hair clip can have good stability.

[0019] Please refer to Figures 1 and 5. The present invention allows the hair clip to be shortened when a relatively small amount of hair needs to be clipped or when the volume of the hair clip needs to be reduced for easy portability. The upper positioning body 44 can be joined and positioned with the third reduced positioning groove 532, and the lower positioning body 42 can be joined and positioned with the first reduced positioning groove 152 and the second reduced positioning groove 252 in the up and down directions, respectively, and the width of the hair clip is kept unchanged while maintaining the shortened state, thereby providing good stability to the hair clip.

[0020] In the present invention, when excessive force is applied when unfolding the hair clip as shown in Fig. 4, the upper positioning body 44 can be joined to the third unfolding positioning groove 531, and the lower positioning body 42 can be joined to the first unfolding positioning groove 151 and the second unfolding positioning groove 251, respectively, for positioning. Therefore, excessive unfolding is ensured, and the assembly of the first rotating shaft 14, the second rotating shaft 24, the third rotating shaft 43 and the first pivot hole 41 and the second pivot hole 52 can be stably maintained, and the assembly can be provided with good stability.

[0021] In this way, the present invention can improve the effect of stabilizing the unfolding, expanding and folding of the hair clip.
