Description

Magnetic button

Technical field

The present invention relates to magnetic fastener, especially main mat magnetic attraction and reaching to untiedly the magnetic fastener of fastening is right each other.More particularly, but be not limited thereto certainly, it is right to the invention particularly relates to the Magnetic button untied with guiding and anti-slip characteristic magnetic coupling surface.

Background technology

Magnetic fastener or button are very useful in many application scenarios.Unlike traditional button assembly, its fastening and untiing by button being filled in or deviate from button hole and realize, the fastening of Magnetic button are to accomplish by having between complementation or the mutually diamagnetic pair of magnetic button mutual magnetic attraction.This Magnetic button device can untied counter pair fastening automatically when closer to each other, and the Magnetic button of coupling meanwhile can be by being pulled away from button and untiing simply each other.Equally, unlike the fastening sequentially of traditional button assembly with untie, row's Magnetic button fastening simultaneously or untie.These unique characteristics make Magnetic button that many useful purposes be arranged.

For example, Magnetic button is widely used on handbag, simple box and other container, seals easily and opens to provide simple and easy and removed the worry that all goes for the accurate combination of accurate button hole each time from.

Also have, Magnetic button is particularly useful to garment for children, because we know that children are out of patience and come fastening and untie traditional button, and almost being fastening automatically and easily untiing and welcome by children of Magnetic button.Harsh in the winter time place, traditional button is buckled well and untied to the hand that the utmost point is unwilling to extract out them because people often wear gloves, so Magnetic button is particularly useful.

Have, Magnetic button is particularly useful under the environment that need are buckled well and untied in singlehanded and short time again.For example, Magnetic button is useful to artist or performer's clothes, needs the frequent clothes of changing when they perform.Magnetic button is particularly useful to the workman who wears work clothes and protective garment, and this work clothes and protective garment may be hooked by machine or moving article.Pledge clothes or protective garment when being hooked, use the clothes of Magnetic button or work protective garment can make the person of wearing be easy to escape and avoid being hooked and injured by accident.

Magnetic button in this explanation comprises a pair of complementary part, and they utilize magnetic attraction untiedly combination each other.Each can be untied part and comprise plate shape or the sheet shape magnetic part with top and bottom magnetic couplings face usually.The magnetic couplings face is connected to each other by continuous circumferential edges usually, considers that from attractive in appearance and style this circumferential edges is generally done quite thinly.These magnetic sheets or sheet generally are cylindrical shapes and have substantially the same end face and bottom surface.This magnetic sheet or sheet are enclosed in the cover of magnetic usually, and it is available makes such as rubber, nylon, plastics (such as ABS or PVC) or synthetic resin.This cover plays decoration function (this magnetic material has dull and dull metal package usually) and provides the atmospheric corrosion protection to delay undesirable corrosion to magnetic material button by add lid to magnetic material.In this, even if magnetic part is oxidized, cover had better watertightness or bubble-tight, and cover can provide good-looking lid to hide the surface of firmly getting rusty from the outside, therefore makes Magnetic button be applicable to the application scenario that product form and apparent weight are wanted.

The unique property of magnetic fastener or button is: even physically separate when their contacts or in conjunction with preceding quilt, they also can automatically contact and be bonded to each other.Because can untie the magnetic of part, not needing outside help usually just can contact and combination subsequently.For further strengthening the convenience of Magnetic button, Magnetic button is often made the complementary magnetic part with identical shaped and size.Basically equate that in a single day they enter contact as a result owing to can untie the size of the complementary magnetic couplings face on the part, parts will automatically be aimed at.

Yet the Magnetic button of this form need have the magnetic sheet or the sheet of substantially the same shape usually, so the free degree of button structure is subjected to very big restriction.Have, the Magnetic button normally mutual magnetic attraction of the coupling surface by having opposite magnetic pole comes combination, the direction of the strongest bonding force to be substantially normal to or perpendicular to coupling surface again.As a result, the button transversion malposition relatively more easily takes place in relatively more weak and horizontal pulling button of horizontal mutual attraction, and when applying lateral pull, this may cause unintentionally or the dropout of accident.And when the coupling surface of rough or friction is set, can delay undesirablely laterally to move, this selection simultaneously will reduce the self aligned easy degree between the coupling surface inevitably and suction is reduced.Therefore, hope can provide improved Magnetic button, and it can alleviate the known disadvantage of traditional Magnetic button.

Summary of the invention

Therefore the purpose of this invention is to provide Magnetic button, but their autoregistrations and the ability of resisting undesirable lateral shift is preferably arranged basically.Another object of the present invention provides Magnetic button, and its shape not exclusively depends on the shape of magnetic part, and provides the raising Magnetic button to resist the device of the ability of undesirable horizontal dropout simultaneously.Further purpose of the present invention is to select and use that to provide be the interchangeable selection of Magnetic button design at least for the public.
