Background technology
The women underwears such as existing brassiere, body modelling dress are mainly made using cloth, and the characteristic of cloth causes comfortable and easy to wear.
And underwear is generally provided with arc-shaped steel ring to the support effect of breast in the cup lower edge pad of underwear in order to better improve.Most
Early steel ring is the steel ring of circular cross-section, and this steel ring has the contradiction for being difficult to reconcile, if that is, larger using rigidity
Steel ring, although it has higher supporting force, more preferable moulding effect, but its flexibility is poor, is used in underwear wearing
When, steel ring can form steel ring impression around breast, reduce the comfort of user;If using the less steel ring of rigidity, though
So cause the more soft wearing comfort sense of steel ring more preferably, but after a long time use, steel ring, which is easily deformed, distort, etc. shows
As especially in washing process, steel ring is easy to deformation, so that underwear produces not personal effect, wearing comfort sense
Decline.
Therefore, also can be moulding in order that comfortable purpose can be reached when in use by obtaining steel ring, many underwear producers are all right
Steel ring carries out various improvement.The brassieres support as disclosed in Application No. 02249376.X, it is used is set to bottom thickness two by brassieres support
End gradually thinning structure, so that it is during use, both can be strengthened rigidity and be held by bottom thicker one section
Towing force, while again flexibility gradually can be ensured thinning two sections by its two ends.As Application No. 200620058554.8 is public
The brassieres support opened, bluff body is used in the middle of it, and two ends use the structure of column, and supporting force is solved to a certain extent and is relaxed
The problem of adaptive.
Either the steel ring of circular cross-section is still by deforming obtained steel ring, and its deficiency existed is exactly, and the two of steel ring
End easily punctures underwear, moreover, the end of steel ring is when extruding breast, user's foreign body sensation is strong, comfort level is reduced, for non-
The steel ring of circular cross-section, realizes the additional processing means complex operation of deformation, increases cost, reduces efficiency.
The content of the invention
In view of this, user's foreign matter can be reduced it is an object of the invention to overcome the deficiencies of the prior art and provide one kind
Sense, and ensure support effect on the premise of lifted comfort level underwear steel rim of spring.
In order to solve the above-mentioned technical problem, the present invention is realized using following scheme:
A kind of underwear steel rim of spring, including arc-shaped steel ring, the end of the steel ring provided with can free deformation elastic portion.Underwear
Effect is to keep breast to fetter breast formation in a relatively-stationary scope, therefore underwear.User is in static
During state, on the premise of suitable underwear is worn, underwear can't produce great foreign body sensation to human body.But, user
It can not possibly remain static forever, its most time is the state in activity, traditional steel ring is hard metal
Material, when breast is swung, the end of steel ring easily forms the strong point in the inner side and outer side of breast, compared with small area of contact feelings
Under condition, foreign body sensation is protruded, and reduces comfort, and What is more can cause the local red and swollen of breast.Therefore, in steel ring in the application
End sets elastic portion, when breast is swung, elastic portion meeting flexural deformation, and the single strong point will not be formed to breast,
Prevent from forming less contact surface.Furthermore, when breast is swung, steel ring except by breast to its active force in addition to, also
By active force of the body to it, and steel ring is placed in steel ring sleeve, therefore its stressing conditions becomes extremely complex.Elasticity
Portion for can free deformation, can be stretched, bent with the situation of breast, whole process is fitted breast and body kinematics,
It is adapted to stress scene complicated and changeable, improves comfort level.
The elastic portion is spring.The selection of elastic portion has a variety of, such as rubber, spring leaf, by a large amount of of inventor
Experiment, confirms the best results that selection spring is realized.Relative to rubber and spring leaf, the elastic deformation amplitude of spring is maximum, energy
Bent with multiple angles, adapt to the complicated motion in breast periphery, if rubber and spring leaf easily occur deformation it is not enough or
The excessive situation that fracture occurs of deformation amplitude.Secondly, the spring of the end position in steel ring is in the case of stress, at it
Gradually reduced in the probability of bending, compression, extended state, be in most cases stress bending, and by setting the conjunction of spring
Suitable length, will not also destroy its elastically-deformable performance, it is ensured that the service life of steel ring even across multiple bending.
There are various ways the end that spring is fixed on steel ring, such as realizes fixation by the way of by gluing or welding.By
It is usually regular face in the end of steel ring, the mode of gluing is also not easy to produce powerful cohesive force with the end of steel ring, removed
The consumption of non-increasing adhesive, but once increase the consumption of adhesive, certainly will be in corresponding underwear position shape after adhesive solidification
Into protuberance, increase discomfort.Be fixed according to welding, welding can produce burr, easily puncture underwear, and spring with
Both carry out welding and are not easy, therefore, the application looks for another way by steel ring small volume, by setting cladding steel ring and spring
Pipe sleeve so that the end of spring close to steel ring is fixed.Rubber or flexible plastic may be selected in the material of pipe sleeve.By the setting of pipe sleeve,
Spring is fixed on to the side of the end of steel ring, it is to avoid the shortcoming of above-described other fixed forms.Secondly, sleeve pipe is by steel ring
It is integrated with spring cladding, globality is stronger, and avoids the tip of steel ring or spring from puncturing underwear.Pass through the phase of sleeve pipe and spring
With reference to enhancing the rigidity of spring, it is ensured that rigidity and flexibility, and the setting of sleeve pipe can prevent the excessive deformation of spring.
It is preferred that, when the diameter of spring is less than diameter/width/thickness of the end of steel ring, when spring stress is bent, the end of spring
It can prevent from being arranged into steel ring in excessive be extruded repeatedly in the case of stress of spring diameter using the end of steel ring as impetus
End, causes the rupture of pipe sleeve with the change of spring position.
The end of the steel ring is coated with gum cover.Here the effect of gum cover is the end of cladding steel circle, to prevent end
Burr/tip puncture pipe sleeve or underwear.Further, since spring is in bending, the end of steel ring is used as spring impetus, gum cover
Setting increase frictional force with spring, and gum cover belongs to soft material, can limited spring to a certain extent shifting
It is dynamic so that gum cover is burst in the end that spring will not be offset from steel ring in bending, for the spring of energy free deformation, matches somebody with somebody
Rubber alloy set largely secures its relative position.
The application provides further scheme, and the end of the steel ring forms arrow nozzle structure so that spring is set in thereon.
Spring and the steel ring end is coated using end pipe sleeve.In such scheme, spring only tube set is fixed, and underwear is repeatedly
Washing rear casing is easily broken off in spring with steel ring joint, therefore is tentatively fixed spring by arrow nozzle structure in the application,
Prevent from forming stress concentration point, end pipe set is further coated and fixed, and so just reduction spring and the pipe sleeve of steel ring contact position go out
The probability now ruptured.Due to being coated to whole steel ring, there is a situation where after washing a small amount of water stain into internal, the row of being difficult
Go out, the application only coats the steel ring end where spring and arrow nozzle structure by end pipe sleeve, it is to avoid the entrance of water.In the application
Tentatively fixed by arrow nozzle structure, end pipe sleeve is not easy abjection, by testing fatigue, spring is fixed by arrow nozzle structure, can
To be subjected to 100,000 bendings without impaired.
The spring includes the pars intermedia between end and end, and the pitch of the end of the spring is less than pars intermedia
Pitch.The spring of end in steel ring is when stress is bent, and the end of spring is squeezed and pars intermedia is stretched, and is passed through
The pitch of the end of spring is reduced in advance so that is tended to be intensive between the adjacent coils of its end, is prevented the pitch of its end
It is excessive and compression when cause the tip of spring to puncture pipe sleeve.
It is as described above, further to find to prevent from puncturing pipe sleeve by the pitch for the end for reducing spring in advance,
When being in contact between the adjacent coils of the end of the spring, i.e. the pitch of the end of spring is contracted to zero, the longevity of pipe sleeve
Life can be greatly improved.Reason is, when the end of spring still has certain pitch, spring bending, although now
The degree of the end compression of spring is not obvious, still, when spring is to curving, this corresponding side of end of spring
It is compressive state, the opposite side of the end of spring is then extended state, and the end of spring gum cover corresponding with the end of steel ring
It is not what is seamlessly transitted(Work as spring bending, the end of spring is just separated with the end of steel ring so that corresponding gum cover part is in
Now stretch), now the corresponding position of gum cover is in the presence of the end of spring and the end of steel ring, easy aging fracture so that
Spring is completely separated with steel ring.
Further, the length of the spring is 1 ~ 2.5cm, and the length of its end is 1.5 ~ 5mm.Pass through suitable length
Set, can prevent that partial portion is only existed caused by spring is long to be bent and the unbending phenomenon in other positions, it is to avoid spring mistake
Length, which ties up unnecessary position, causes the shortening of steel ring length, then reduces support strength.The length of the end of spring, which is set, to be made
Obtain its end and be not easy excessive deformation, and enable the pars intermedia of spring to carry out stretch bending with most suitable length, it is ensured that
Softness.
The angle that the line vertical with the tangent line of the end of steel ring intersects is 110 ° ~ 155 °.Further, the angle is 120 °
~140°.As described above, as the steel ring inserted in underwear, it is necessary to keep rigidity and flexibility, and the end of steel ring can not
Any injury is produced to underwear/human body.In the application, by the setting of above-mentioned angle, steel ring is contacted with the lower half of breast,
Main support effect is played, the length of steel ring both will not cause underbraced by short-range missile very much, and long and fully wrapped around will not also cause
Discomfort, is adapted to the chest type of overwhelming majority crowd.Moreover, when angle is 120 ° ~ 140 °, being particularly suitable for having the use for gathering demand
Person, can guarantee that the effect of gathering of breast, and under the spring effect at two ends, the sense of discomfort brought is gathered in reduction.
Compared with prior art, the present invention has the advantages that:The application is set at the two ends of steel ring can free form
The elastic portion of change, elastic portion free bend when being pressurized is deformed, and is prevented the end of steel ring from forming the single strong point to breast, is protected
Comfort is improved on the premise of card support effect.It can realize that multi-angle is bent as elastic portion using spring, adapt to breast periphery
Complicated motion, further improves comfort.Pass through the pipe sleeve that cladding steel ring and elastic portion are set so that elastic portion is close to steel ring
End fix, by steel ring and elastic portion cladding be integrated, globality is stronger, it is to avoid the tip of steel ring or spring punctures underwear.
