Description

The locking folder

Technical field

The present invention relates to hair preparation, hair clip for example, wherein first jaw is hinged with respect to second jaw by the joint with longitudinal axis, so that pivot between open position and closing position, each jaw all comprises the jaw body that is provided with one group of tooth.Each jaw comprises all that generally one is used for the operating lever of open and close hair clip.Hair clip is generally used for a part of hair is kept together.

Background technology

This class hair clip for example illustrates in patent documentation US5873377, US5664591, US2004/0149306 or EP1023853.

Hair clip is kept by the return spring device usually, and this return spring device is pushed two jaws to closing position.Usually helical spring is used as the return spring device.

Therefore, the confining force that hair clip is held in place in hair is the effect with respect to the size of hair clip of the effect of the return force that applies of helical spring and helical spring.

Therefore, correspondingly select helical spring, so that provide enough maintenance effects to hair clip energetically by what jaw is pushed to closing position.

First shortcoming is, the maintenance effect of hair clip is good more, and then helical spring power is big more, and the jaw that the user utilizes operating lever to open hair clip becomes difficult more.

Another shortcoming is, too big infringement user's the hair easily of hair clip applied force, and make assembling hair clip difficulty is because be pre-tensioning before assembling at assembling interval helical spring.

At last, use the helical spring with high return force to need operating lever, described operating lever increases along with the variation of helical spring return force dimensionally in order to help opening hair clip.The operating lever that consequently needs size may seem inconvenient, attractive and not bigger.In addition, the existence that becomes whole operating lever with jaw has limited the shape that jaw can be produced.In fact, the jaw of hair clip and lever mostly with plastics by injection moulding production.Therefore, the Compulsory Feature of jaw with lever can be taken out from mould easily, that is, do not have undercut shape, this undercut shape hinders them by extracting the direction translation and extract from the marking of mould towards one simply easily.Thisly requisitely need to hinder the creator seek the attracting shape of creating object, the maintenance hair is not only in the effect of this shape, but also beautifies and decorate hair.

Document US 2004/0040569 A1 has illustrated a kind of bobby pin, and this bobby pin comprises first and second jaws, and first and second jaws join mutually around an axis perpendicular to the longitudinal direction of jaw, so that pivot between open position and closing position.The releasable retaining mechanism that is arranged on the jaw with joint opposed free ends place makes the user bobby pin can be locked at closing position, perhaps bobby pin is unclamped so that it turns back to open position.

In this bobby pin, the specific orientation perpendicular to the axis of jaw longitudinal direction in jaw joint causes jaw separately very big at open position.For this reason, this bobby pin is placed on user's the head, especially beginning closed it the time, obviously and necessarily need to utilize user's both hands and certain skill at least.Now, the user hand has been used for before the assembling bobby pin hair being held in suitable shape.Therefore, it is very difficult to assemble bobby pin for this reason.

In addition, after mobile jaw was approaching mutually, the user can only keep the bobby pin closure with a hand, but in order to lock two jaws, still must implement auxiliary operation (promptly locking member self being applied torsion) with his another hand.Therefore, when the user wishes to use this bobby pin, there is the user can not repair his hair and correctly that hair is fixing highly dangerous, because this bobby pin complicated operation.

Summary of the invention

First problem that the present invention solves is to design in the hair that remains on the user that provides good and hair clip easy to use.Especially, the object of the invention is to guarantee the good confining force of the jaw of hair clip in the closing position, and needn't not need the specialized operations retaining mechanism to come closed hair clip at the operation hair clip so that it overcomes high return spring mechanism power when being closing position or open position yet.

Therefore, must only operate hair clip so that with the hair clip closure with a hand.

Simultaneously, the object of the invention is that the clamping force of avoiding excessive injures user's hair, and is convenient to assemble during manufacture hair clip.

The specific embodiment

Fig. 1-9 illustrates 5 different embodiment of the present invention with 12-16.In each figure of these accompanying drawings, hair clip all comprises first jaw 1 and second jaw 2, described first jaw 1 and second jaw 2 extend on longitudinal direction I-I, and are hinged by the joint 3 with longitudinal axis I-I, so that pivot between open position and closing position.First jaw 1 and second jaw 2 include

jaw body

1a or 2a separately, and described jaw body is provided with one group of

tooth

1b or 2b separately.

At open position,

jaw

1 and 2 is separated from each other, and promptly their

tooth group

1b or 2b are separated from each other.In closing position,

jaw

1 and 2 is mutually closed, that is their

tooth group

1b or 2b are closed mutually, so that clamp the part of user's hair between them.The tooth of

tooth group

1b or 2b preferably intersects in closing position.

Return spring mechanism 4 always pushes two

jaws

1 and 2 to open position.The power of return spring mechanism 4 does not need height.It must just enough offset when the user hold hair clip make this hair clip when hair moves by user's applied force.Releasable retaining mechanism 5 only just is locked at closing position with

jaw

1 and 2 automatically when

jaw

1 and 2 is moved relative to each other, and does not need other intervention of user.

In first and second embodiment shown in Fig. 1-4, retaining mechanism 5 comprises at least one opening 6, and the jaw body 1a that described opening runs through first jaw 1 forms.Retaining mechanism 5 also comprises at least one from the elasticity prong 7 that second jaw 2 extends towards first jaw 1, and this elasticity prong has a hook shaped distal end 7a, and is suitable on side direction and flexibly deflection.Elasticity prong 7 optionally is suitable for: (a) by hook shaped distal end 7a being bonded in the opening 6 that runs through first jaw 1 and closing position with first jaw 1 keep with second jaw 2 at a distance of a fixed range d place, perhaps (b) flexure unber lateral of utilizing elasticity prong 7 is left and is unclamped first jaw 1 by making hook shaped distal end 7a pass opening 6.

In the embodiment of Fig. 1-4, hook shaped distal end 7a has a front surface 70a, and this front surface slides on the edge of opening 6, thereby causes the slight deflection of elasticity prong 7 when this far-end 7a enters in the opening 6.Far-end 7a also comprises stop surface 71a, after elasticity prong 7 stretches into opening 6 enough distances, once more on side direction during towards the direction slight deflection relative with caused first flexure unber lateral of front surface 70a, above-mentioned stop surface keeps first jaw 1 apart from second jaw, 2 one fixed range places.

In first embodiment shown in Fig. 1 and 2,

jaw

1 and 2 extends on longitudinal direction I-I, and each jaw all has two

end

1c, 1d and 2c, 2d.The tooth of

tooth group

1b and 2b is from remote edge 100a and the 200a horizontal expansion of jaw body 1a and 2a.The tooth free end of

tooth group

1b and 2b forms the remote edge of

jaw

1 and 2.

Hair clip comprises two elasticity prongs 7, and described two prongs 7 remote edge 200a from jaw body 2a on side direction extends towards the jaw body 1a of first jaw 1.Elasticity prong 7 lays respectively at the vertical end 2c and the 2d place of second jaw 2.Elasticity prong 7 can form integral body with jaw body 2a or be attached on the described jaw body 2a.

Hair clip shown in Fig. 1 and 2 simple to operate.Return spring mechanism 4 is helical spring 4a at this, and this helical spring has two the outstanding longitudinal ends by corresponding jaw, and this return spring mechanism 4 always pushes two

jaws

1 and 2 to open position, and

tooth group

1b and 2b are separated from each other in described open position.

When the user wishes hair clip is placed on when last, orientation that he is limited towards

arrow

9a and 9b (Fig. 2) and direction apply a slight extruding force on jaw 1 and 2.When mobile hair clip only, extruding force can be low, hair clip remained in his hand get final product.Then, when hair clip is in place in hair, the user is with bigger

power extruding jaw

1 and 2, overcoming the return force that is applied by helical spring 4a, and

jaw

1 and 2 moved relative to each other to the hook shaped distal end 7a of elasticity prong 7 enter opening 6 among the jaw body 1a.Hair clip is in closing position as shown in Figure 1 then, and under the situation that does not need any auxiliary operation of user auto lock.In fact clamp mechanism 5 comprises elasticity prong 7 and opening 6, and hair clip one arrives its closing position, and above-mentioned elasticity prong 7 and opening 6 just automatically hook mutually.The hook shaped distal end 7a of elasticity prong 7 makes first jaw 1 and second jaw 2 be held against helical spring 4a with fixed range d.

When the user wishes when his hair takes off hair clip, he can be for example by his forefinger and thumb, and the direction that is limited towards

arrow

10a and 10b applies extruding force to each elasticity prong 7.The user causes the flexure unber lateral of prong 7 thus, thereby makes the far-end 7a of elasticity prong 7 can pass opening 6.Therefore the user unclamps first jaw 1, and first jaw 1 moves away from second jaw 2 by return spring mechanism 4 then.

Therefore, obviously, hair clip is convenient to operation and is convenient to by two fingers, and for example between the forefinger and thumb of the same hand, very natural compressional movement compresses separately.

Advantageously, elasticity prong 7 is set, so that hair clip is along its whole length balance at each the end 2c and the 2d place of second jaw 2.Thereby hair clip is not easy to twisting owing to the effect of return spring mechanism 4.

When the hair clip that for example uses as illustrated in fig. 1 and 2, elasticity prong 7 can enter user's hair.Therefore very as seen retaining mechanism 5 is not, and can not reduce the visual and attracting outward appearance of hair clip.

Fig. 3 and 4 illustrates the second embodiment of the

present invention.Jaw

1 and 2 has the general structure identical with first embodiment.Hair clip comprises the elasticity prong 7 of single buckle shape far-end 7a herein.Elasticity prong 7 is carried by second jaw 2 near joint 3.As more specifically finding out among Fig. 4, elasticity prong 7 is in the vertical with respect to the end 2c skew of joint 3 towards second jaw 2.Elasticity prong 7 can become integral body with jaw body 2a or be attached on the described jaw body 2a.

First jaw 1 has an opening 6 that runs through this jaw, and described opening is near joint 3 and opposed with the elasticity prong.

This hair clip uses the mode identical with the hair clip shown in Fig. 1 and 2 to operate.

In the time of on hair clip being placed on user's head, the user applies force on the

jaw

1 and 2 of hair clip towards direction and the orientation that

arrow

9a and 9b (Fig. 4) are limited, so that

jaw

1 and 2 is closed on the hair.During this closing motion of

jaw

1 and 2, the hook shaped distal end 7a of elasticity prong 7 enters the opening 6 that runs through first jaw 1.

Jaw

1 and 2 one reaches closing position, the clamp mechanism 5 that comprises elasticity prong 7 and opening 6 is just automatically hooked mutually, and overcome the effect of return spring mechanism 4 but first jaw 1 keep with second jaw 2 at a distance of a fixed range d, this return spring mechanism 4 comprises helical spring 4a at this.Therefore hair clip remains in closing position as shown in Figure 3.

In order to take out hair clip from hair, the user applies power towards orientation and the direction that arrow 10c (Fig. 4) is limited.Therefore the user makes deflection on the elasticity prong 7 energy side direction, so that make the far-end 7a of elasticity prong pass opening 6, thereby first jaw 1 can be thrown off.Return spring mechanism 4 makes two

jaws

1 and 2 can turn back to their open position then, as shown in Figure 4.

This hair clip operation is fairly simple.Elasticity prong 7 is included among the inner space E between the

jaw

1 and 2 of hair clip.So elasticity prong 7 not too as seen, and do not reduce the attracting outward appearance of hair clip.Elasticity prong 7 also is placed near the joint 3, so that help to keep it and prevent that it from becoming entangled in user's the hair.

Elasticity prong 7 is in the vertical with respect to the end 2c skew of joint 3 towards second jaw 2, so that the user can be pressed on the direction that a finger is limited towards arrow 10c on the elasticity prong 7 to separate hair clip.

Obviously, this hair clip is convenient to operation and is convenient to by with two fingers, and for example forefinger of the same hand and thumb compress separately with the motion of nature.

Elasticity prong 7 is placed and any imbalance of can not inducting in hair clip near joint 3 very much: even retaining mechanism 5 includes only an elasticity prong 7,

jaw

1 and 2 also keeps being parallel to each other basically.

According to a kind of improvement of the present invention, except hook shaped distal end 7a, also one or more ratchet 7b can be set on elasticity prong 7.In the embodiment of Fig. 2 and 4, elasticity prong 7 is included near the ratchet 7b the far-end 7a.Therefore hair clip has many closing positions, and described closing position going up apart from d between jaw 1 and 2 (Fig. 1 and 3) is different mutually.This makes the locking of hair clip can adapt to the variation of user's hair volume.

Fig. 5 and 6 illustrates the third embodiment of the

present invention.Jaw

1 and 2 also have with first embodiment in identical general structure.

In this embodiment, retaining mechanism 5 comprises opening 60 and retaining ring 11, and the jaw body 1a that above-mentioned opening 60 runs through first jaw 1 forms, and the jaw body 1a of the above-mentioned retaining ring 11 and first jaw 1 forms one.Retaining mechanism 5 also comprises elasticity prong 7, and described elasticity prong 7 extends towards first jaw 1 from second jaw 2, and comprises operating side 7c and hook spare 12.When hair clip was placed in the hair, the user made

jaw

1 and 2 capable of pivoting relative to each other against return spring mechanism 4, automatically be hooked on the retaining ring 11 until hook spare 12 so that in closing position, make first jaw 1 keep with second jaw 2 at a distance of a fixed range d.

During the closing motion of hair clip, the operating side 7c of elasticity prong 7 passes the opening 60 in first jaw 1, and reaches the outside of opening 60 when hair clip is in the close position.

In closing position, operating side 7c therefore can be by the user near also being operated.

When the user wished to take out hair clip from hair, it applied force on the come-at-able operating side 7c that plays prong 7 towards orientation and the direction that arrow 10d is limited.Therefore the user makes elasticity prong 7 deflection on side direction, and the effect of flexure unber lateral is that hook spare 12 is moved away retaining ring 11.Then

jaw

1 and 2 turn back to them by return spring mechanism 4 (Fig. 5) open position to leave mutually.

Retaining mechanism 5 can be made of metal, so that more wear-resistant and be attached on the remainder of hair clip 5.

Retaining mechanism 5 is contained among the inner space E between first and

second jaws

1 and 2, and therefore not too as seen, thereby does not reduce the attracting outward appearance of hair clip.

Retaining mechanism 5 also is convenient to upward clamp and operate by the come-at-able operating side 7c that applies pressure to elasticity prong 7 simply.

Jaw

1 and 2 reliably is firmly held in the closing position by hook spare 12 and retaining ring 11.

Fig. 7-9 illustrates the fourth embodiment of the

present invention.Jaw

1 and 2 have with first embodiment in identical general structure.

In these accompanying drawings, retaining mechanism 5 comprises at least one retaining ring 11 and at least one elasticity prong 7, the jaw body 1a of the above-mentioned retaining ring 11 and first jaw 1 forms integral body, and above-mentioned elasticity prong 7 extends from second jaw 2 towards first jaw 1, and has operating side 7c and hook spare 12.

When using this hair clip, the user is placed on hair clip in the hair, applying extruding force by the effect that overcomes return spring mechanism 4 to first and

second jaws

1 and 2 moves relative to each other described

jaw

1 and 2, be bonded in the retaining ring 11 until hook spare 12, so that first jaw 1 in closing position (Fig. 8) is kept and the second jaw fixed distance d.

As shown in Figure 9, in this embodiment, two elasticity prongs 7 can be set, each elasticity prong 7 comprises the first hook spare 12a and the second hook spare 12b separately, the described first hook spare 12a is designed to be bonded among the corresponding first retaining ring 11a and the second retaining ring 11b with two relative directions with the second hook spare 12b, the above-mentioned first retaining ring 11a and the second retaining ring 11b offset with respect to each in the vertical, keep

jaw

1 and 2 to be parallel to each other so that increase.

In closing position, operating side 7c can by the user near and can be operated.

In order to open hair clip, the user is applying extruding force to the operating side 7c of elasticity prong 7 on the longitudinal direction shown in arrow 10f and the 10g.Hook spare 12a and 12b leave retaining

ring

11a and 11b then, thereby return spring mechanism 4 can be separated from each

other jaw

1 and 2.

Obviously, hair clip easy operating and being easy to by with two fingers, for example between forefinger of the same hand and the thumb with the compressional movement of nature separately.

In third and fourth embodiment shown in Fig. 5-9, hook spare 12 is shaped, so that be close together and can clamp automatically at jaw 1 and 2.Therefore hook spare 12 has a front surface 120a, described front surface 120a slides on the edge of retaining ring 11, makes the 7 slight upwards flexure unber laterals of elasticity prong to such degree, promptly simultaneously, wherein hook spare all is bonded in the retaining ring 11, and fixes second jaw 2 by stop surface 121a.

type prong

21a and 21b extend towards second jaw 2 from first jaw 1, and having separately distal portions 210a, 210b and proximal part 23a, a 23b, described distal portions 210a and 210b have horizontal cut 211a and 211b separately on perpendicular to the band breach side surface 22a of offset direction II-II and 22b.Proximal part 23a and 23b depart from one second length L 2 from distal portions 210a and 210b and elasticity prong 7 along offset direction II-II.Described second length L 2 is more than or equal to first length L 1.

When the hair clip shown in use Figure 12-17, the user implements first and

second jaws

1 and 2 first relative motions respect to one another.Push back the cross member 20 of elasticity prong 7 by side surface 22a jaggy and 22b then, and make elasticity prong 7 elastic deflections.Because the effect of the return spring mechanism of elasticity prong 7, continuing first relative motion at first and

second jaws

1 and 2 when closing position is rotated then can be bonded on far-end cross member 20 among the horizontal cut 211a and 211b of hook-

type prong

21a and 21b automatically.Therefore, hair clip one arrives its closing position, and the retaining mechanism 5 that is made of elasticity prong 7 and hook-

type prong

21a and 21b automatically is hooked in together mutually.Hair clip keeps being locked at closing position then, as shown in Figure 13.

Although the hair clip shown in Figure 12-17 has horizontal cut 211a and 211b with a ratchet, it is contemplated that on each hook-

type prong

21a and 21b a plurality of ratchets are set, so that can regulate the jaw 1 of hair clip and 2 clamping, the person's of being used hair.This guarantees the good applicability of the hair style that hair clip is looked for user's hair and user.

When the user wishes that when hair took off hair clip, it implemented first and

second jaws

1 and 2 second relative motions respect to one another, as more specifically illustrating in Figure 14 and 15.The far-end cross member 20 of elasticity prong 7 becomes corresponding relation (Figure 14) with the proximal part 23a of hook-

type prong

21a and 21b with 23b then.Because the effect of the return spring of elasticity prong 7, far-end cross member 20 strides across the space between proximal part 23a and the 23b, and is moved beyond hook-type prong 21a relative with 22b with side surface 22a jaggy and surperficial 22a ' and the 22b ' of 21b.Then, the effect of return spring mechanism 4 is by implementing first and

second jaws

1 and 2 relative motions that separate toward each other around axis I-I rotation, to return the open position of hair clip shown in Figure 12.

In the 5th embodiment shown in Figure 12-17, each hook-

type prong

21a and 21b wrap holder protuberance 27a and 27b.These protuberances tell the user to stop the time of first motion respect to one another of first and second jaws 1 and 2.Far-end cross member 20 is bonded with each other and produces after the click in horizontal cut 211a and 211b, and the user will feel owing to

protuberance

27a and 27b resistance that produce, that first relative motion is proceeded.

At the far-end cross member 20 of elasticity prong 7 and proximal part 23a with before 23b becomes corresponding relation,

protuberance

27a and 27b also when second relative motion respect to one another of first and

second jaws

1 and 2 with elasticity prong 7 flexibly to pusher.Because elasticity prong 7 will be pushed back along long route by

protuberance

27a and 27b before this, so elasticity prong 7 returns elastically the surperficial 22a ' that exceeds hook-

type prong

21a and 21b and 22b ' with more convenient, quicker and safer.Therefore,

protuberance

27a and 27b have increased the operation ease and the reliability of the hair clip of fifth embodiment of the invention.

In the embodiment of Figure 12-17, second jaw 2 can comprise a resilient protection blade 24, and described resilient protection blade 24 is positioned at the outside of retaining mechanism 5 with respect to joint 3, and 1 extends from second jaw 2 towards relative jaw, finds out as best among Figure 16.When closed hair clip, resilient protection blade 24 keeps user's hair away from joint 3, return spring mechanism 4 and retaining mechanism 5.This resilient protection blade 24 also can be positioned on first jaw.

In specific embodiment shown in Figure 16, resilient protection blade 24 has one towards the curved distal end 24a away from the direction in joint 3.When closed hair clip, this far-end 24a then slides on the inner surface 101 of jaw 1, so that locking retaining mechanism 5.When sliding on the inner surface 101 of far-end 24a at jaw 1, to pusher, away from joint 3, return spring mechanism 4 and retaining mechanism 5, thereby promotion user's hair leaves them to resilient protection blade 24 by inner surface 101 elasticity of jaw 1.

Should note, in different embodiment, retaining mechanism 5 can easily be adapted to the hair clip in any use joint 3, described joint 3 can perhaps comprise sheet spring 16 as the 4th and the 5th embodiment shown in Fig. 7-9 and the 12-17 as comprise articulated elements 3a in first, second and the 3rd embodiment (Fig. 1-6).In first, second and the 3rd embodiment, return spring mechanism 4 comprises helical spring 4a, and in the 4th and the 5th embodiment, return spring mechanism 4 comprises sheet spring 16.Sheet spring 16 preferably is made of metal such size, and this size is suitable for the rigidity that provides good on joint 3 and produces
