Description
Technical field
Present invention relates in general to fastener, more particularly relate to the fastener of magnetic, for example the strap fastener of the clasp of magnetic and clasp, magnetic or belt fastener.More particularly, be not limited to these certainly, the invention still further relates to clothes such as brassiere used such as fasteners such as clasp or clasps.The invention still further relates to the clothes that have magnetic fastener.
Background technology
At traditional fastener assembly, for example in row's button, by button being inserted in the button hole or button is buckled or untied the mode that button is separated out from the button hole, Magnetic button is different with this traditional fastener with magnetic fastener, Magnetic button and magnetic fastener by having complementation or mutually diamagnetic a pair of complementation magnetic fastener or the mutual polarity between the Magnetic button by fastening or fixing.This specific character of magnetic fastener means that when the pair of separable magnetic fastener was close mutually, this can be by fastening automatically to magnetic fastener.Simultaneously,, and these fasteners are moved apart mutually, the fastener of these snappings is separated as long as the fastener of these snappings or button are drawn back.In addition, with fastener in the tradition for example the difference of button assembly also be: traditional button must or be untied by preface fastening successively, the button of row's magnetic then can be simultaneously by fastening or be untied simultaneously.
Because magnetic fastener has above-mentioned distinguishing characteristics, therefore, under the situation that need all buckle these fasteners or untie at short notice with a hand, this magnetic fastener is just particularly useful.For example, for performing artist or performer's stage costume, because performing artist or performer need to change continually stage costume in drama, therefore, magnetic fastener will be of great use.Very useful for the work clothes that magnetic fastener may be blocked by machine or moving article for dress and the workman of protective garment.If clothes or work protective garment have magnetic fastener, so, when the protective garment of pledging clothes or work is unexpectedly blocked, can throw off at an easy rate, thereby avoid the wearer to be clamped or injured.
As mentioned above, general magnetic fastener comprises the parts of a pair of complementation, and these complementary parts releasably interconnect by polarity.Each separable parts generally includes a magnetic element, this magnetic element in block form or sheet shape, and have a top magnetic and connect the surperficial surface that is connected with a bottom magnetic, have opposite magnetic pole on the surface in surperficial connection of said top magnetic connection with bottom magnetic.These magnetic connect the surface and are interconnected by continuous periphery usually, and for the attractive in appearance and consideration style aspect, said continuous periphery is extremely thin usually.The shape of said magnetic block or magnetic piece is cylindrical usually, and has essentially identical top surface and basal surface.
But magnetic block or magnetic piece are got up by the shell enclosure of a magnetic conduction usually, but the shell of this magnetic conduction is made by for example rubber, nylon, fabric, plastics (for example ABS or PVC) or synthetic resin.Magnetic element has dull and dark metal appearance usually; this shell just can be decorated magnetic fastener by the outer cover that is designed beautifully is provided to this magnetic element; and can corrode protection for magnetic material provide, so that delay or prevent undesirable getting rusty.From this aspect, seal shell preferably watertightness or bubble-tight, like this, even oxidation has taken place in magnetic element, seal shell and still can play the effect of ornamental outer cover,, make the surface of getting rusty can not be exposed to the outside so that can cover up the surface of getting rusty, therefore, this shell of sealing makes Magnetic button be applicable to the product of those emphasis outward appearances and appearance.
In order further to improve the convenience and the applicability of magnetic fastener, magnetic fastener generally is made of the magnetic element with identical shaped and big or small complementation.Because connecting the surface, the magnetic of the complementation on the separable parts has essentially identical size, therefore, in case these parts are in contact with one another, these parts will automatically be aimed at basically, and the initial contact of these parts and joint subsequently all need not outside help usually.
Because magnetic clasp or clasp have many like this advantages, therefore, can predict, magnetic recording tape or strap fastener (for example bar bracelet and clasp) will certainly be adopted more widely, and especially for example in the applied environment that clasp is difficult to get at or is difficult to locate or during use clasp is hidden in the applied environment of other surface underneath basically.As an example of these application, this clasp or clasp are used in chemise or the brassiere, and in chemise or brassiere, clasp or clasp are usually located at the back, or are positioned at the place that is not easy to get at.Another example is the braces that is used for trousers, and in the braces of trousers, some such fasteners will be fixed on the rear portion of trousers.In these were used, the outward appearance of fastener was normally very important, because the selection of these fasteners is considered to represent or reflected user's grade sometimes.
Up to now, the clasp of magnetic or clasp also do not resemble and are widely used the expection.Its main cause is exactly traditional magnetic clasp and the magnetic clasp is very complicated, expensive, heavy, plain usually, volume is big probably, and is difficult to sometimes use.
Traditional magnetic fastener is difficult to use usually, this is because the magnetic of traditional magnetic fastener is strong inadequately usually, can not be reliably said magnetic to being fixed together, so, traditional magnetic fastener is typically provided with additional engagement device, to prevent that magnetic is to unexpectedly breaking away from.When wanting to make magnetic to disengaging, this additional engagement device can bring inconvenience again.In addition, because Magnetic button is characterised in that by the mutual magnetic attraction between the connection surface with opposite or complementary magnetic pole and is bonded with each other, and it is because the strongest usually in the roughly normal direction or the connection of the magnetic on the vertical direction power on said connection surface, therefore, mutual lateral attraction quite a little less than, and side direction draws these buttons that the side direction separation will take place at an easy rate, when applying a side direction pulling force, fastener is unexpectedly broken away from like this.Though can be covered with connection surface mat or friction property and prevent and be displaced sideways unexpectedly by providing,, this can make these connect between surfaces usually and be not easy to aim at voluntarily, therefore is not wise selection.Therefore, magnetic fastener can be widely used, just must satisfy conflicting like this requirement, that is: when wanting fastener separated easily fastener separately, and fastener should be by fastening securely together in other cases.
For example, in european patent application No.EP923887, disclose a kind of magnetic encapsulation piece, this encapsulation piece provides mutual locking for sack, knapsack and clothes.This device combines magnetic encapsulation piece and overlap joint (snap-acting) encapsulation piece, and said overlap joint encapsulation piece includes a pair of protruding part and recessed parts.In a preferred embodiment, protruding part forms a projection, and this projection comprises a snap close, and this snap close is used to be inserted in the groove of recessed parts, so that locking mutually, thereby prevent the nature slippage.The user just can and separate two parts releases by protruding part is pushed.This project organization can need two actions to come the encapsulation piece release, and these two actions are: draw back magnet and protruding part and recessed parts are opened.
Therefore, provide such magnetic clasp ideally, this magnetic clasp overcomes at least or has alleviated aforesaid a part of defective, thereby strap fastener in light weight, reliable, simple can be provided.Preferably, this strap fastener should have the structure of profile height little (low-proflie), so just can be easily and on clasp, add some decorations easily, so that make these clasps more pleasing, if the magnetic clasp can be widely adopted in chemise, fashionable dress or clothes, this decoration of clasp is exactly a very important aspect.In addition, low-profile structure can also reduce usually to outer cover or the adjacent hurtful danger of flexible material.Yet, the little design of profile height in the tradition usually cause magnetic between magnetic engagement power enough big, therefore, up to now, this profile height not macrostructure adopts complicated additional engagement device to be still inevitably.Therefore, thrown off if this fastener can overlap according to user's wish to cooperate and can be easy to, that will be very desirable.
In whole specification, for brevity, and this simple and clear degree is that term: fastener, clasp and button are used interchangeably under the suitable situation for context.
Summary of the invention
Therefore, an object of the present invention is to provide a kind of in light weight, simple in structure and cheap magnetic strap fastener or clasp.In addition, for the purpose of attractive in appearance, this strap fastener or clasp should have low-profile structure, so that can be easily and be hidden in easily under clothes or other surface, thereby make and for example can adopt this fastener widely when brassiere or chemise making underwear.Preferably, this fastener need not to adopt the engagement device of additional complexity to prevent unexpected and disadvantageous disengaging.Just in this point, this fastener be designed to can magnetic between provide very strong magnetic to engage, the while can easily untie this fastener again as required, this also is a purpose of the present invention.

The specific embodiment
At first, expressed a magnetic element 10 and a shell 20 among the figure, when magnetic element 10 and 20 is assembled together, just constituted the magnetic clasp of first preferred embodiment of the invention referring to figs. 1 through Fig. 3.Magnetic element 10 is to produce the source be used for the magnetic engagement power that engages with the magnetic clasp that matches.Preferably, this magnetic element comprises a permanent magnet, and this permanent magnet is the form of magnetic sheet, and is made by the material or the alloy of strong magnetic, so that the very big magnetic force and the ratio of volume to be provided, thereby makes the structure of this clasp very compact.Adopt current magnetic technique, diameter is that a pair of complementary magnetic sheet that 1cm, thickness are about 1mm and have an appropriate configuration described herein can produce the magnetic engagement power up to 20-30N.
In this preferred embodiment, it is circular or cylindrical that magnetic sheet is essentially, and diameter is about 12mm, and thickness is less than 1mm.For maximum magnetic engagement area is provided, two opposite magnetic pole preferably are set on two opposite planar 11,12 of magnetic sheet, so that make the arctic be positioned on one of them plane, and the South Pole is positioned on another plane, and has a perisporium 12A between them.In order to increase the magnetic flux density on the composition surface, magnetic element preferably is embedded in the housing, and this housing can be by magnetic material, and for example iron, steel or other iron magnetic shell are made, and one of them magnetic engagement surface is exposed.By a strong magnet is set, just can strengthen the magnetic intensity of the composition surface that is exposed in a concentrated manner widely on iron magnetic shell.Certainly, also can adopt magnetic element equivalently and be without loss of generality with other shape and thickness.For example, magnetic element can be made as the section shape of rectangle, polygon, trapezoidal even irregular or non-geometry.In addition, can also adopt magnetic element ring-type or curved surface shaped.
Shell comprises: a support part 21 or an acceptance division is used to receive magnetic element; One band receiving unit 25 is used to keep a flexible ends of a band, so that can releasably engage with a magnetic clasp that matches.The magnetic element support partly comprises a base part 22 and a upright perisporium 23, said base part 22 preferably and the bottom size sizes of magnetic element be close, said upright perisporium 23 extends upward along the periphery of said base part.This combining structure of base part and perisporium provides a chamber shell, and said magnetic element is received in this chamber shell, makes magnetic engagement surface 11 come out and be not blocked.This chamber shell comprises base part 22 and upwardly extending perisporium 23, and this chamber shell is preferably made by magnetic material, for example by making such as the ferromagnetic material of chromium or nickel-plated steel etc.Magnetic element can be bonded in the shell of chamber, or is held by alternate manner, and said alternate manner comprises mechanical keeper or embedding.If compare with the magnetic element of not sealing like this, when magnetic element is sealed and makes a surface to come out by magnetic material, the magnetic intensity of the magnetic surface that is exposed will be reinforced and maximize, and when this magnetic element engaged with the relative magnetic surface 10 of the magnetic clasp that matches of similar structures, said magnetic engagement power will be improved greatly.Adopt this structure, just can obtain more compact structure, clasp that magnetic intensity is stronger.
In the present embodiment, the band receiving unit comprises a rigidity bridging part, and this rigidity bridging part extends with side direction or mode radially along the direction away from the chamber shell.In this structure, the band receiving unit is equal substantially apart from the distance of two pole surface, and this band receiving unit links to each other with the chamber shell by rigidity bridging part 27.Preferably, bridging part 27 comprises a band-like plate element, and the wide surface of this band-like plate element is arranged essentially parallel to magnetic and connects surface 11,12.Certainly, also can not adopt ribbon element, but adopt a thin rod element that said band receiving unit and chamber shell are coupled together.Under any circumstance, the housing parts that extends away from the chamber shell should have very thin profile, thereby can have low-profile structure on the whole.For example, as shown in the figure, the major part of extension is preferably flat, and entire portion should remain in the height of perisporium of magnetic element 10.Or the band acceptance division can be set near the perisporium that connects said pole surface 11,12, thereby makes this band acceptance division equal substantially apart from the distance of two pole surface 11,12.The band acceptance division is arranged on the side direction of pole surface, the low-profile structure that will obtain to wish.
With reference to Fig. 4, expressed the magnetic clasp that matches of a pair of complementation among the figure, this is in the magnetic engagement state to clasp, as can be seen, has the clasp A that matches on magnetic engagement surface 11 of opposite magnetic pole and the magnetic engagement surface of B and is in the physics contact condition.Have identical structural design described above although should be noted that the clasp that preferred scheme is two complementations,, also can adopt the different clasps that still have complementary character of structure to be used as a clasp that matches or a fastener.
