Description

Hair clip with improved fastening mechanism and manufacturing method thereof

Technical Field

The present invention relates to hair clips, and more particularly to hair clips having improved fastening means and methods of making the same.

Background

There are different types of hair ornaments on the market for gripping hair and/or providing ornamentation to the user. These different ornaments may be somewhat helpful in achieving hair gripping and ornamentation, but many of these ornaments suffer from the common problem of not being able to ensure that the hair is tight enough when needed, and not being able to be easily disengaged when not needed. In some conventional hair ornaments, the structure tends to create areas such as gaps that allow the hair to be caught and the hair to break. While in other conventional hair ornaments the construction or method of manufacture is too complex, resulting in difficulties in making reliable ornaments and/or in making them expensive. Generally, such fittings are often not durable.

The present invention is directed to solving these problems, or at least to providing the public with alternative solutions.

Detailed Description

The present invention relates to hair clips having an improved fastening mechanism and methods of making the same.

A first embodiment of a hair clip according to the present invention is shown in figures 1 to 9. The hair clip, reference numeral 2, has a generally elongate profile.

Figures 1 to 2 show the open form of the hairpin. The clip 2 has an elongate decorative member 4 which, in use, is intermediate an outwardly directed surface 6 and an inwardly directed surface 8. The outward surface 6 has a convex profile and the inward surface 8 has a concave profile. The outwardly facing surface 6 has an aesthetically pleasing design. The inwardly facing surface 8 is configured to be coupled to a snap-fit device 10 for gripping a bundle of hair, as described in further detail below.

Still referring to fig. 1-3, the clip 2 is provided with the fastening means 10, the fastening means 10 also having an elongated profile. In this embodiment, the trim member 4 is substantially larger than the fastening device 10 such that the fastening device 10 is hidden and not visible. The length and width of the fastening device are about 7.5cm and 1.3cm, respectively. However, experiments with the present invention have shown that feasible length and width dimensions are 4-12cm and 0.92-1.38cm, respectively. The results show that the feasible ratio of the width of the lip to the length of the lever should be between 0.92: 12 to 1.38: 4 in the middle. When the lever is relatively long, the width of the lip cannot be too narrow, otherwise the lever will accidentally disengage from the continuous member. On the other hand, when the lever is relatively short, the width of the lip cannot be too great, otherwise the lever will not be able to disengage easily from the continuous member when depressed. It should be understood that all of the above dimensions and dimensional ranges of the closure device 10 of the present invention are not arbitrary, but have been developed after a significant amount of research and development. All research and development results show that not any dimensions are functional, but that some combination of length and width of the snap means, such as the reference numeral 10, according to the invention will allow the operation of the clip 2 in a feasible, reliable and efficient manner. All of the importance of the dimensional characteristics of the fastening device 10 will become more apparent after the description of the other features.

Fig. 4 to 5B show the hair clip 2 in side view, bottom view and sectional view, respectively. Other views of the trim member 4 and the fastening device 10 are also shown.

Referring to fig. 6 and 8, the snapping device 10 generally comprises a base member 12, the base member 12 being adapted to be coupled to the inward-facing surface 8 of the trim member 4 and a lever 14. The base member 12 is provided with first and second members 16, 18 at opposite ends thereof. The second member 18 is generally a floor 20 having a seat-like form, an upstanding wall 22 extending from the floor 20, and the seat-defining recess 24. The upstanding wall 22 is provided with apertures 26 on opposite sides thereof. By "upright" is meant the condition of the hair clip 2 when the outward surface 6 of the decorative member 4 is directed downwardly (i.e. towards the base plate as shown in figure 3) and the inward surface is directed upwardly (i.e. away from the base plate as shown in figure 3).

The second member 18 has a plurality of holes, one of which is provided as a connection to the trim member 4. Fig. 6 shows that the inwardly facing surface 8 of the trim member 4 is provided with a pair of studs, namely a first stud 28 and a second stud 30, the first and second studs 28, 30 extending outwardly from the inwardly facing surface 8. When the trim member 4 is formed by plastic in a one-time injection molding step, the studs 28 and 30 are formed uniformly. The second member 18 is provided with an opening at the base plate 20 sized to receive one of the studs. The second member 18 is fixedly secured to the inward facing surface 8 at the root post 30 by a snap fit and/or welding of the second member at the root post 30. It should be noted that there are no additional components (e.g., metal pins or rivets) used to secure the second member 18 to the root post 30.

The lever 14 has an elongated profile and has opposite ends, a first end 32 and a second end 34. The second end 34 is provided with protrusions 36, 38 on opposite sides thereof. The projections 36, 38 are sized and shaped to fit within the aperture 26 of the upstanding wall 22 of the second member 18. It can be seen that with this arrangement, the snap means 10 is adapted to adopt a first configuration in which the lever 14 is pivotally lowered, or the snap means 10 is adapted to adopt a second configuration in which the lever 14 is pivotally raised about a hinge mechanism formed by the second member 18 and the projections 36, 38. In other words, the lever 14 may be hingedly moved toward or away from the base member 12.

Referring at least to fig. 6-7A, the first member 16 also has a similar horizontal floor 40 and a member 46 that is substantially upstanding from the floor 40. However, the upstanding members 46 of the first member 16 are distinct from the upstanding walls 22 of the second member 18. The upstanding wall 22 is sufficiently rigid and does not substantially change shape during use. The upstanding member 46, on the other hand, is relatively thin, resilient and bendable, and is described in more detail below.

In this embodiment, the upright member 46 has a pair of legs 48, 50. The upright member 46 has a lip 52 extending generally laterally from the upper end of the upright member 46, the lip 52 closing the legs 48, 50 to form a continuous member in the form of a ring 54. The lip 52 resembles the shape of the letter "U" when viewed at least from above. It will thus be appreciated that the combination of the upstanding member 48 and lip 52 forms the continuous member/ring 54 or continuous member. The continuous member 54 defines a cavity 56, the cavity 56 being sized and shaped to fit over the first end of the lever 32. The continuous member 54 is resilient and flexes the legs 48, 50 away from the second member 18 when the lip 52 is depressed toward the inner surface 8. It will thus be appreciated that the continuous member 54 may be curved away from the second member 18 or the lever 14, or toward the second member 18 or engage the lever 14, which determines the curved position of the continuous member 54.

The configuration of the U-shaped lip 52 has a narrow width. See "" < - > "in FIGS. 8A-8B. In this embodiment, the lip has a width or thickness of 1.5-2.5 mm. However, a feasible range is 1-4 mm. This width or thickness is not arbitrary, but is in accordance with the dimensions of the fastening device or at least the lever 14 generally has the length of the fastening device 10.

Referring to fig. 7B, the base member 12 includes a bridge portion 60, the bridge portion 60 connecting the first and second members 16, 18, the base member 12 being elevated from the inward surface 8 of the trim member 4. The lifting portion 62 of the bridge portion 60 has a cushion 64. The material from which the lifting portion 62 is made is different from the cushioning pad 64 on the lifting portion. The importance of the selection of the material will be discussed later. In any event, the bumper pad 64 serves to increase the engagement and grip that the fastening device 10 imparts to the hair during use. In this embodiment, the lifting portion 62 is in the form of an elongated plate 66. However, in other embodiments, the raised portion may be in the form of a pair of ribs arranged in parallel.

In this embodiment, the lever and the locking member preferably have a bending strength of 31MPa + -10% and a Shore D hardness of 55 + -10%. These material properties are not arbitrary, but may allow the snapping devices to remain in a locked configuration when desired, and to be unlocked when disengagement is desired.

Fig. 8A to 9 show the operation of the clip 2 during use. Specifically, fig. 8A shows the open state of the hairpin 2. This shows the lever 14 hinged to the second member 18 and clearly in a position above the base member 12 and the bridge portion 60.

Fig. 8B illustrates that the bridge portion 60, including the cushion 64, is resilient and may assume a generally horizontal configuration in a default setting or a downwardly curved configuration in a depressed setting. The setting is illustrated by the arrows in fig. 8B.

Fig. 9 shows that in the open configuration, a user can position the clip 2 such that a bundle of hair to be bound is positioned between the lever 14 and the bridging portion 60. Once achieved, the lever 14 is moved to the first member 18 for locking.

Referring to fig. 10A, the lever 14 approaches the first member 18, the lever 14 first approaches the upper side of the lip 52, and then the lever 14 begins to abut the upper side of the lip 52 while the continuous member 54 is still in its original state, i.e., the undeformed or unflexed configuration. In this home configuration, the lip 52 is held in position as the path of travel "P" of the lever 14.

Referring to fig. 10B and 10C, further movement of the lever 14 deforms the continuous member 54 as the lip 52 moves outwardly from the bridge member 60 and the upstanding members 46 correspondingly flex outwardly, thereby allowing the lip 52 to move out along the path of movement "P" of the lever 14. The extent of lateral movement of the lip 52 is determined by the width and position of the lip 52. When the lip 52 is aligned with the lever 14 in its original position, the required range of motion is substantially the width of the lip 52. As the lip 52 moves out, the lever 14 can move further on its path of movement so that the lever 14 presses against or at least approaches the bridging portion 60. Please refer to fig. 10C in particular. The effectiveness of the lever 14 being locked by the lip 52 may be determined by the length of the lever 14 or the snapping device 12. When the lever 14 or the snap fitting device 10 is too long and the lip 52 is too narrow, any slight relative or accidental movement of the lever 14 and the continuous member 54 may undesirably cause the continuous member 54 to unlock the lever 14.

Referring to fig. 10D and 10E, further movement of the lever 14 positions the first end of the lever past and finally below the lip. Due to all of the inherent resiliency of the continuous member 54 (including the upstanding member 46), the lip 52 flexes back to its original, original position as the first end of the lever 14 is now located under the lip 52 and retained within the cavity of the continuous member 54.

Fig. 10F shows the closed state of the hair clip 2, in which the lever 14 is fixed. It can be seen that the continuous member 54 serves both as a lock for the lever 14 and as an actuator or control for the locking. It will be appreciated that closure of the closure means 10 may be effected by a one-handed operation. In other words, moving the lever 14 and the trim member 4 together and locking the lever 14 to the continuous member 54 are performed in a one-handed operating action.

Fig. 10A to 10F illustrate how the hair clip 2 is moved from the open state to the closed state, and fig. 11A to 11D illustrate how the hair clip 2 is moved from the closed state to the open state. Referring to fig. 11A, when the user wants to remove and not use the hair clip 2, the lip 52 is moved toward the decoration member 4 by pressing the lip 52 to the decoration member 4 using, for example, a thumb and an index finger. Referring to fig. 11B-11C, the force of the press moves the continuous member 54 away from its original position, causing the lever 14 to disengage from the underside or lower surface of the lip 52 and release from the locked position.

Referring to fig. 11C and 11D, this shows the elastic tendency of the bridging member 62(66) to return to its horizontal position pushing the lever 14 away so that the lever 14 passes the lip 52. The back and forth alternation of the lever 14, which is locked away from the decorative member 4 or the continuous member 54, of the lever 14 is an action performed by a one-handed operation.

In one embodiment, a method of producing the hairpin comprises the steps of:

a) forming an elongated lever from a first plastic in a single injection molding step;

b) forming a base member comprising a bracket structure, a latch member and a hinge member from a second plastic in a single injection molding step, wherein the hinge member has a recess in which the lever is connected and received by the hinge, the latch member is an upright and tongue-like form movable member;

c) a cushion member formed of a third plastic material by plastic molding on a middle portion of the support structure;

d) attaching one end of the lever to the hinge member to assemble the lever to the base member, thereby forming a snap-fit arrangement;

e) assembling the fastening device to a decorative member by a connecting method selected from the group consisting of cold or hot pressing including snap fittings, thereby forming the hair clip.

The first plastic and the second plastic are preferably the same material. The third plastic is different from the first plastic and the second plastic. The production method of the hair clip does not use any metal parts.

Hairpins designed according to the present invention are multiple advantageous in structure and function. First, the number of parts involved is small. For example, in the above illustrated embodiment, there are only two moving or movable parts, namely the lever and the continuous member. Secondly, the snap-fitting means, i.e. the whole hair clip, is composed of two parts, i.e. the base member and the lever, with the exception of the decorative member. The base member, including the first and second seat members, is made by a single injection molding step using a plastic. Even if the base member is provided with a cushion for increasing the frictional engagement of the bundled hair, the entire base member is formed by at most two injection molding steps. Further, assembling the fastening device to the decorative member may be performed without using any metal rivet device. Finally, engaging or disengaging the lever with the continuous member may be by pressing the lip and the trim member together with one hand. The range of motion of the lip or the required depression force of the lip is small.

It is to be understood that several features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, the descriptions of a single embodiment may be provided separately or in any suitable subcombination for the sake of brevity. It is noted that certain features of the described embodiments are shown by way of non-limiting example. Moreover, no description is provided as to prior art that would be apparent to one skilled in the art for the sake of brevity.
