Description

A kind of magnetic clasp and clothes and luggage and accessory using the magnetic clasp

Technical field

The present invention relates to a kind of magnetic clasp, belong to the required portion of human lives by International Patent Classification (IPC) (IPC) division, it is personal or Household goods branch, clothes major class, the button group in dress ornament haberdashery, more specifically, it relates to a kind of frivolous small and exquisite Magnetic clasp, it can be widely applied to clothes, underwear, leatherware, shoes, luggage, accessory to constitute fastening/opening system.

Background technique

Button is for clothes, as handware for furniture, has conclusive effect to its function.The mankind The setting fastening mode of clothes has occurred certain variation from ancient times to modern times, the localized variation of this setting fastening mode but make moderns with The clothes of ancients have huge difference on the whole, and a small step of setting fastening mode progress often corresponds to the one of clothes progress Big step.The clothes of ancient Chinese are by based on belt system.The benefit of belt system is the tightness of adjustable clothes, is allowed to It is more fit, but its modern life that can not adapt to high rhythm in terms of comfort level；Button is the main body system of modern clothing Button mode, though button is small, its appearance, undoubtedly clothes setting fastening mode a revolution, it is used than the mode of frenulum Convenience and agile degree be obvious to all, but it is due to needing out buttonhole, and clothes have been formed once being made, similar ancient times The clothes of frenulum mode just disappear the adaptability and regulatory function of body.And the appearance of magnetic clasp, then to following clothing belt Finer prospect is carried out.For magnetic clasp because dependence magnetic force is oriented to, wearing/take off clothes can be more more convenient than the common button of use, Meanwhile because it does not need out buttonhole, it is possible to convenient displacement, or by way of point to multi--point, carry out position It adjusts.Therefore, magnetic clasp can have both the advantages of frenulum and button, so being expected to become after button, another is available Universal new setting fastening mode, to realize clothes great development again and innovation.But current magnetic clasp design still has It is many insufficient, so that magnetic clasp is cancelled out each other with respect to the advantage of button with weak tendency, still it is not enough to complete the update to button.

] prior art about magnetic clasp, we have done a large amount of analysis, retrieval and research to existing technical literature, although With existing technological means cannot understand completely all related inventions, but this itself do not lose one well analysis compare simultaneously Try hard to generate the method for more having innovation and practical value scheme.By analysis we have found that the prior art summed up it is following several A type:

The first kind, too simple applied invention: this kind of invention is only that magnet is answered in different dress ornament kinds or the simple of position With lacking to the design of the structure of magnetic clasp itself, it has not been convenient to nail catcher or the not formed lock function to transverse shifting, such invention Quantity is a lot of, represents patent such as: CN200620045404.3 (a kind of magnetic force button), CN201120027394.1 (magnetic clasp and Shirt with the magnetic clasp), CN201120341743.7 (nightwear with magnetic clasp), CN201220146381.0 (magnet hook type Decompose shoes), CN201120110833.5(magnetic buckle type leather belt), the trousers of CN200720079051.3(carry magnet knocker), CN200910063000.5(setting Magnetic hasp belt), a kind of magnetic clasp belt of CN201220217899.9(), A kind of magnetic clasp brassiere of CN201620340655.8(), the dedicated magnetic clasp of CN200720112396.4(baby clothes) etc..

Second class, excessively complicated functional form invention: this kind of invention has complicated structure, while to realize its complicated knot Structure just need have very thick or very big body, general character be it is at high cost, be not easy to suture, be not suitable for clothes.It represents special Benefit such as: CN201010508945.6 (modified form magnetic clasp), CN200910105391.2 (a kind of rotary magnetic button structure), CN201610909216.9 (magnetic clasp and the object with magnetic clasp).

Third class, ease is moderate, but is not suitable for the practical invention that clothes use: this kind of invention is general also thicker, It is generally all fixed by metal leg, is not easy to suture, it is now to be usually used in luggage more, but be not suitable for clothes.Represent patent Such as: TW081205846 (Novel magnetic snap), CN200920052996.5(case magnet hook), CN201020181876.8(mono- Kind of magnetic clasp), CN201220288647.5 (magnetic button structure of magnetic loop), CN201420425747.7 (magnetic clasp) etc..

4th class, ease is moderate, also clothes is suitble to use, but the still defective invention of structure: such as patent CN93233792.9(magnetic clasp), defect is that shape is blocked up, and magnetic force structure is bad, and suction is weak, main sewing hole in periphery, Be inconvenient to use button-sewing machine stitching；For another example patent CN200410097861.2 (magnetic hasp element), defect be it is not thin enough, no With lateral displacement blocking function, also inconvenient button-sewing machine suture；For another example (magnetism is by fastening by patent CN201580028471.6 Firmware), defect be it is thicker, size is larger, and buttonhole is with based on the periphery, it has not been convenient to button-sewing machine suture；For another example patent CN201120253780.2 (anti-theft magnetic snap), structure are to be closed the magnetic line of force by being formed in permanent-magnetic clamp, but contact area is small, Suction is weak.Separately since the pitch of holes of stamping parts and hole and bending circular arc point of contact distance generally require the distance of two material thickness or more, In addition the necessary gap etc. of component has reached so the practical feasible diameter made of button will at least reach 20MM or so Coin-size belongs to bigger size, limits its extensive use, in addition, magnet periphery is not covered completely, Bu Nengbao It protects frangible magnet and installation not easy to produce and is unfavorable for armoured magnetic field when in use, be possible to reducing magnetic field to the greatest extent to making The adverse effect that user generates.Magnetic clasp edge is arranged in the preferable magnetic clasp design sutured that can have been seen at present, buttonhole Position, non-stop layer can suture texture, conventional button-sewing machine operation can not be used when stitching, cause working efficiency lower.And buttonhole exists The position at exterior angle, because stamping parts needs geometries and the mechanical technologies such as certain hole back gauge and hole and bending circular arc point of contact distance Reason, so planar dimension is big, and thickness is partially thick, is especially unsuitable for the clothes for shirt or other yarns, silk fabric etc light and thin fabric Dress.

Magnetic clasp to be done thin.Because magnetic clasp will be arranged between clothes two sheets, if magnetic clasp thickness is big, it will cause Biggish gap will affect the functions such as the warming and masking of clothes.

Magnetic clasp to be done sufficiently small.Because clothes are the synthesis of function and vision, for button, thumbnail (diameter 14mm or less) with coin-size (diameter 20mm or so) although diameter has only differed several millimeters, area can but be differed Twice or more, therefore be completely different in visual effect: the former can be placed on bright face the vision for also less influencing clothes Effect, and the latter then can be very eye-catching, must generally be made into hidden discount, and distance when while being hidden in cloth increases actuation, In order to guarantee magnetic force, it is necessary to the more volume of plus magnetic clasp, so that vicious circle is formed, and excessive permanent magnet is because being difficult to Full-shield is easily magnetized so biggish excessive magnetic field can be generated to can have to the people or periphery for being equipped with pacemaker Situations such as article, generates potentially hazardous.And for shirt, the button diameter normally followed closely is in 13mm or so, and thickness is in 3mm Left and right.The button dramatically increased than this size is all unsuitable to shirt in terms of weight and usage comfort.And for making With the clothes of frivolous fabric, unsuitable property of the biggish magnetic clasp in vision and function then can be more significant.Because of magnetic clasp Size is all very big for the visual impact of the function of clothes, so our considering to be not up to and haggle over every penny in size Stage.Certainly, magnetic clasp is small not absolute, opposite, and the diameter of magnetic clasp will be relative to the diameter of permanent magnet in magnetic clasp It is just more meaningful.Such as the magnetic clasp of overcoat, allow simultaneously to be suitble to the magnetic clasp of diameter 20mm or more, but it is corresponding its to magnetic force It is required that also to increase, it is inadequate that the diameter for being suitable for shirt, which is no more than the permanent magnet of 10mm, so good structure designs Mainly to try hard under specific permanent magnet diameter, the overall diameter of magnetic clasp is small as far as possible.The area of plane and absorption of button The ratio between pulling force, we are called product effect ratio.Product effect is more related than with the shared space proportion of permanent magnet, also related with magnetic structure, such as Fruit can use good magnetizer to constitute preferable closed magnetic circuit, then adsorb that pulling force is stronger, and product effect ratio is higher.On the other hand, button edge Part occupied area for suturing fixed part rather than being used to constitute magnetic circuit is smaller, then product effect is than higher.

But under such as above-mentioned smaller relatively thin size, magnetic clasp preferably axial adsorption capacity and radial restraining ability are realized, and And low cost is wanted, easy to produce, it is highly difficult for being also convenient for suture.Currently, still can not find one kind simultaneously in the prior art Have both it is at low cost, it is easy to produce, easily use, the magnetic clasp for several respects advantage such as thickness is thin, is correspondingly small in size, and magnetic force is strong.And this, exactly The starting point of the invention.

Specific embodiment

The present invention includes two panels as magnetic clasp in the prior art, this two panels can be different, and generally to allow two Piece is not easy to misplace when adsorbing, it is desirable to a piece of structure for having protrusion, and another has recessed structure.In the present invention, , there is center to have opposed projections point are a piece of to be insertion element, corresponding another on the contrary is called receiving element for we.

Substantially there are two types of mode, one kind relying only on permanent magnetism piece itself and formed without additionally increasing magnetic conduction construction for the absorption of magnetic clasp Absorption, this mode is simple but inefficient.Another suction type is then mutually to be tied by permanent-magnet material with permeability magnetic material It closes, to form the closed magnetic circuit formed by good magnetic conductive material, this magnetic texure is called good magnetic conduction closing structure, then to beat The closed state for breaking this good magnetic conduction closing structure just needs the strength of Fei Geng great, therefore forms closed state by good permeability magnetic material Structure have higher magnetic suck efficiency.It can make volume smaller in the case where guaranteeing that adsorption capacity is certain.Institute of the present invention The structure of use is exactly this good magnetic conduction closing structure.In good magnetic conduction closing structure, and there are two types of modes, and one kind is in permanent magnet Periphery forms closed magnetic circuit, and one kind being centrally formed closed magnetic circuit in permanent magnet, we are respectively called them the good magnetic conduction in periphery and close Close structure and the good magnetic conduction closing structure in center.It can certainly be respectively formed good magnetic conduction closing structure with inside in periphery, but this Take into account occupancy is the area of permanent magnet, so not but not obviously increasing adsorption capacity, can also reduce suction on the whole on the contrary Attached power, thus this structure not we the considerations of column.The good magnetic conduction closing structure in periphery and the good magnetic conduction closing structure in center exist Be on magnetic adsorbability it is similar, they all form the good magnetizer closed circuit of the magnetic line of force.But its space hold has very big Difference, just, we compare discovery by a large amount of, on the one hand facilitate the suture of button-sewing machine in center setting sewing hole, On the other hand again consistent with the target of volume is reduced, so present invention employs the good magnetic conduction closing structures in periphery.And it is of the invention The used good magnetic conduction closing structure in periphery is made of annular permanent magnets and magnetic conductive disk, and so-called annular permanent magnets refer to center Have hole to form the permanent magnet of suture texture accommodation space, annular permanent magnets can with insertion element or receiving element respectively in connection with, In the present invention, for convenience, we are referred to as the first annular permanent magnets and the second annular permanent magnets, therefore, the One annular permanent magnets or the second annular permanent magnets belong to annular permanent magnets, and only fixed position is different.

Magnetic clasp is sewn on soft fabric sheet, what this suture was completed generally by silk thread.This is just needed It wants to reserve hole or other structures convenient for bondage in magnetic clasp.And it is not easy to use metal as the magnetic clasp for being mainly used for luggage Or nonmetallic pin is completed.In order to realize minimum volume, the position of hole needs the technique in conjunction with magnetic conduction construction and detailed It considers.The constituent material of good magnetic conduction construction is to have based on the metal of ductility and stamping resistance, and for the precision of small size Metal processing, Sheet Metal Forming Technology is generally used to process, to realize high-precision and low cost.And Sheet Metal Forming Technology is that have centainly Feature and requirement.Sheet Metal Forming Technology be by means of the power of conventional or dedicated stamping equipment, make plate in mold directly by Deformation force is simultaneously deformed, to obtain the production technology of the product parts of certain shapes, size and performance.Stamping parts and casting Part, forging are compared, and there are thin, even, light, strong characteristics.Workpiece accuracy is up to micron order, its precision is high, specification is consistent, Neng Gouchong Extrude hole nest, boss etc..Punch process is the main method of sheet metal plastic processing.Therefore, the preferred side of processing of magnetic conductive disk Formula is based on punching press.And punch process there are certain requirements structure design because being limited by mould strength and part quality, Such as pitch of holes, hole back gauge, aperture, hole bending moment etc..Not less than two material of hole back gauge of general stamping parts are thick, and pitch-row disintegrates curved circle Arc point of contact distance is preferably also the distance more than two material thickness, otherwise can hole stretcher strain.This characteristic based on stamping parts, if The position in the hole set is huge on the influence of the size of magnetic clasp.The present invention is convenient for the suture of magnetic clasp, is designed to magnetic conduction construction The inner hole structure at center.Magnetic picture may be implemented in the case where in design in this way, and the overall diameter of magnetic clasp is smaller, this is under us It will specifically be compared and illustrated in case cited by face.Certainly, it must be to rush that the present invention, which does not limit magnetic conduction construction, Pressure technique is made, and other such as castings, forging, 3D printing manufacturing method are also allowed, when we consider the realization of non punching technique When good magnetic conduction construction, find they it is similar with stamping parts there is the associated factors such as size, structure, cost, equally , such as inner hole structure of the present invention can occupy smaller space, and therefore, inner hole structure is not only for Sheet Metal Forming Technology A kind of structure of practicable is similarly outstanding magnetic conduction construction design for other production technologies.

Good magnetic conduction closing structure of the invention is related to two concepts of magnetic conductive disk summation depth and annular permanent magnets summation thickness. In the present invention, magnetic conductive disk summation depth refers to the sum of the depth of insertion element and receiving element；Annular permanent magnets summation thickness Refer to the sum of the thickness of the first annular permanent magnets positioned at insertion element and the second annular permanent magnets positioned at receiving element.When only In insertion element there are when annular permanent magnets, annular permanent magnets summation thickness is exactly the first annular permanent magnets in insertion element Thickness；When insertion element and receiving element are all there are when annular permanent magnets, annular permanent magnets summation thickness is exactly insertion element On the first annular permanent magnets thickness and receiving element on the second annular permanent magnets the sum of thickness.In the present invention, it is The good magnetic conduction closing structure of composition, so cooperate annular permanent magnets summation thickness with magnetic conductive disk summation depth.But Due to the presence of the error of reality, in the case where not accomplishing annular permanent magnets summation thickness situation identical with magnetic conductive disk summation depth, Annular permanent magnets summation thickness less than normal can then be more advantageous to the collision of reduction permanent magnet in magnetic conductive disk summation depth and generate Fragmentation.

Based on being collectively formed by inner hole structure, the first cyclic annular magnetizer structure and by good magnetic conduction closing structure in periphery etc. Innovation structure design, the present invention can also have several structure changes.First, it can also increase by the second ring-type in receiving element Permanent magnet.The directed force of magnetism contraposition when being fastened with increasing.Second, it can add the structure of crimping at magnetic conductive disk edge.? In the case that magnetic conductive disk edge is straight, insertion magnetic conductive disk and reception magnetic conductive disk are tight because combining, and are hard to turn on.Especially magnetic clasp exists It does not follow closely when on clothes, pairs of packaging is generally wanted to place.And two elements are difficult that separately fiber crops can be brought to subsequent processing It is tired.When partially or fully there is curling at magnetic conductive disk edge, then on the one hand open can be easier, on the other hand, can make appearance it is more smooth, Beauty, so and feasible.Third, it can add the structure being auxiliarily fixed at magnetic conductive disk edge.Inner hole in the present invention Structure is easy for machine suture, but frequently use will bear to be possible to earn compared with high-tensile strength disconnected, and single-point is fixed with and may make It is not docile enough in conjunction with magnetic clasp at fabric sheet, easily make clothing that warpage and deflection occur in suture stress point, and assist suture Structure can solve this problem.Auxiliary suture texture is generally used for secondary suture when necessary.The present invention gives two classes are auxiliary Help suture texture to design: one is the auxiliary suture texture that no less than two petal calvus are constituted, the spies of petal calvus Sign is the gradually laminated structure of bulging along magnetic conductive disk Center wizard disk edge direction.Such shape, when suture is strapped in pawl When the root of piece, the outer rim of bulging avoids suture and falls off under the action of pulling force.And due to not being pore structure, so not It is limited by requirements such as hole back gauges, example below will provide petal claw construction and may be implemented more compared with outer pore structure The comparison explanation of exquisite structure；Another kind auxiliary suture texture is the auricle with hole, but this hole not instead of aperture, big Cutting tip, so also do not limited by requirements such as hole back gauges, example below will provide the auricle structure with hole and outer Pore structure compares the comparison explanation that more exquisite structure may be implemented.It assists suture texture and unique main body suture is different Sample, it assists suture to be not required suture, is required so it can take into account beautiful and reduction outer diameter etc., and it can Such as 2 or 3 stitch points, the requirement of suture strength can be reduced using as few as possible.Equipped with secondary suture function to being used for The button of clothes is very practical.The industrialization ready-made clothes of clothes be by imaginary user's stature be arranged button position, but this A position can not be entirely appropriate for can only achieve basic be suitble to when particular user, this will compel to be essential in actual use The position for the change button that can be convenient.When primary suture, too many stitch points had not only increased the processing capacity of production, but also unfavorable In the dismantling of button, so it is most suitable for still only suturing a seam area.And when having determined particular user, button Position can determine, then can by auxiliary suture to increase intensity, because have main body suture mode it is quick positioning with suture, assist Suture either by machine or artificial, all alleviates difficulty and intensity.The important function of this and animal often all has double The principle of organ or a main standby difunctional implementation is identical and very necessary.

The embodiment of the present invention is illustrated below in conjunction with attached drawing and its subgraph.

Fig. 1 a is the plan view of insertion element 1 in Fig. 1.Fig. 1 b is the plan view of receiving element 2 in Fig. 1.Such as Fig. 1 a Shown, insertion element 1 includes magnetic conductive disk 5 and the first annular permanent magnets 4, magnetic conductive disk 5 in insertion element 1 we be known as being inserted into Magnetic conductive disk；The plane of first annular permanent magnets, 4 two sides is respectively the pole N and the pole S, is fixed on insertion magnetic conduction by the plane of side Disk obtains on inner bottom surface.As shown in Figure 1 b, receiving element 2 includes magnetic conductive disk 5, magnetic conductive disk 5 in receiving element 2 we be known as connecing Receive magnetic conductive disk；Circular its internal diameter of magnetic conductive disk bottom d3's that the reception magnetic conductive disk is constituted is dimensioned to slightly be greater than from slotting Enter the diameter of the first annular permanent magnets 4 of 1 protrusion of element.It is dimensioned in the magnetic conductive disk bottom internal diameter d3 of receiving element 2 It is greater than the diameter of the first annular permanent magnets 4, slightly to allow the first annular permanent magnets 4 that can enter and be maintained at receiving element In the part of the recess of 2 magnetic conductive disk 5.In this basic typical case, the magnetic conduction of insertion element 1 and receiving element 2 5 magnetic conductive disk bottom of disk about has the thickness of 0.4mm, the first annular permanent magnets thickness h 1 about thickness of 0.8mm.Receiving member The magnetic conductive disk bottom internal diameter d3 of the magnetic conductive disk 5 of part 2 can be than the annular permanent magnets outer diameter of the first annular permanent magnets 4 of insertion element 1 D2 has the surplus of about 0.2mm or more to guarantee smoothly plug/unplug, i.e. d3-d2≤0.2mm.In this way, when insertion element and receiving When element is in attracting state, the general thickness of magnetic clasp 3 is about 1.6mm.This thickness be than normal shirt button also than It is thin.And overall diameter is about 11mm -13mm, it is about similar with thumbnail.

It will be understood by those skilled in the art that it is changeable according to the size of application magnetic clasp 1, and therefore, 4 He of the first annular magnet The try to get to the heart of a matter size of internal diameter d3 of magnetic conductive disk also can be changed.Only for signal purpose and only an example of application of the invention is shown And provide dimensions above.

First annular permanent magnets 4, the magnetic conductive disk that magnetic conductive disk 5 in insertion element 1 can be fixed to by adhesive are tried to get to the heart of a matter. However, it will be understood by those skilled in the art that other way can also be used that the first annular permanent magnets 4 are fixed to 1 magnetic conduction of insertion element During disk is tried to get to the heart of a matter, including but not limited to by using interference fit (also referred to as press-fit).The parallel surfaces of first annular permanent magnets 4 In one be coplanar with the bottom side of magnetic conductive disk 5.

As shown in Figure 1 b, insertion element 1 includes 5 annular permanent magnets 4 of magnetic conductive disk., can be formed by soft magnetic materials.The magnetic conduction There is disk 5 magnetic conductive disk to try to get to the heart of a matter and grade N35 or stronger annular permanent magnets 4.In this example, annular permanent magnets 4 can have 10mm outer diameter, 5.5mm internal diameter and 0.8mm thickness.Other diameter and thickness can also be used.As described above, those skilled in the art It will be appreciated that the size of magnetic clasp 3 can change according to application, and the size that therefore the first annular permanent magnets 4 and magnetic conductive disk are tried to get to the heart of a matter can Change.Dimensions above only for signal purpose and provide, and only indicate the example of an application of the invention.

In order to which magnetic conductive disk 5 is fixed to material, 5 center of magnetic conductive disk includes 2-6 inner holes 7 for penetrating magnetic conductive disk 5 and trying to get to the heart of a matter, It is generally matched with button-sewing machine, to be advisable using the inner hole in four holes, to provide channel for suture 8.

Fig. 1 c be in order to engage and be aligned along Fig. 1 a line 1c (1) -1c (1) intercept receiving element and along Fig. 1 b Line 1c (2) -1c (2) interception insertion element sectional elevation.In figure 1 c, receiving element 2 and insertion element 1 are oriented at The combinable or isolated position as indicated by the four-headed arrow between the two.As indicated, when engaged, annular permanent magnets 4 It is directly contacted with the magnetic conductive disk of receiving element 2 face of trying to get to the heart of a matter.

Fig. 1 d is the insertion element 1 of the magnetic clasp 3 of Fig. 1 and the sectional elevation of receiving element 2, and showing will be inserted by suture 8 Enter the mode that element 1 is stitched to sheet material 9.It can be seen from the figure that due to being only one main seam area, so sheet material 9 is when chance When to outside pulling force, warpage or deflection can occur around stitch points.As described above, the first annular permanent magnets 4 can use neodymium Iron boron is as constituent material, it is possible to use other permanent-magnet materials.The constituent materials such as neodymium iron boron can by nickel plating, epoxy coating or The two and protect it to avoid aoxidizing, it is possible to use other inorganic coatings.According to application, the outside dimension of magnetic clasp 3 is changeable.For Receiving element 2 and an acceptable outer diameter of insertion element 1 are 11mm -20mm.The outer diameter of two elements 1 and 2 can be set It is set to identical size, and can accurately punching press or be formed by injection molding.

Fig. 1 d is the insertion element of the magnetic clasp of Fig. 1 and the sectional elevation of receiving element, and being shown will be inserted by line Element and receiving element are stitched to the mode of sheet material respectively.In show and be stitched to insertion element and receiving element respectively by line 8 The mode of sheet material 9.It can be seen from the figure that due to being only one main seam area, so sheet material 9, which is worked as, encounters outside pulling force When, warpage or deflection occur around its stitch points.

Fig. 1 e is sectional elevation of the magnetic clasp of Fig. 1 under 2 attracting state of insertion element 1 and receiving element.Such as figure, this reality The general thickness for applying the magnetic clasp 3 of case is about 1.6mm.

Fig. 1 f is that annular permanent magnets internal diameter d1 is less than inner hole group maximum outer rim distance but is greater than in the magnetic clasp insertion element of Fig. 1 A kind of floor map of practicable mode when inner hole maximum distance of center circle d4.Due to the minimum-value aperture of stamping parts be it is limited, So annular permanent magnets internal diameter d1 is less than the maximum outer rim of inner hole group 70 apart from also possible.This is because suture 8 is suturing When, have interior drawing in the strength in centre, the tight actuation of insertion element 1 and receiving element 2 will not be hindered.Since in this way, Magnetic clasp can be done smaller.In this example, annular permanent magnets 4 can have 8mm outer diameter, 4.5mm internal diameter and 0.8mm thickness.Its Outer diameter can be made 10mm -12mm.In the case, N42 or stronger Nd-Fe-B permanent magnetic can be used in annular permanent magnets 4 Body.So complex chart 1a and Fig. 1 f both of these case, the outer diameter of the magnetic clasp of scheme corresponding to Fig. 1 can be made 10mm- 13mm。

Embodiment 2

Fig. 2, Fig. 2 a, Fig. 2 b are that there are two embodiments when annular permanent magnets for tool.

Fig. 2 is the plan view of the insertion element containing the second annular permanent magnets 41 and receiving element.As shown, the 1 annular permanent magnets 4 are with 41 opposing polarities of the second annular permanent magnets on the contrary, its outside diameter d 2 is matched with internal diameter d1.

Fig. 2 a is along line 2a (the 1) -2a (1) of Fig. 2 insertion element intercepted and along line 2a (2) -2a (2) of Fig. 2 The sectional elevation of the receiving element of interception.It can be seen from the figure that the magnetic conductive disk of the magnetic conductive disk 5 of insertion element 1 and receiving element 2 Although 5 all use the magnetic conduction dish structure that the present invention defines, since in the present invention, magnetic conduction dish structure can have many choosings , so the magnetic conduction dish structure of the two both may be the same or different, just belong in present case it is different, such as Being inserted into magnetic conductive disk depth h01 can be different from reception magnetic conductive disk depth h02.When receiving element being wanted to add the second annular permanent magnets, Being inserted into magnetic conductive disk depth h01 can be with very little, it might even be possible to be zero, a kind of special case of magnetic conductive disk depth here in this way can be bigger Increase magnetic clasp transverse direction restraining ability, but magnetic conductive disk depth h01 is even very little, when being produced for magnetic clasp 3 first it is cyclic annular forever Magnet 4 realizes that being fixedly connected for exactitude position is all good with insertion magnetic conductive disk 5.In the case, the outer diameter ruler of magnetic clasp It is very little to can be made 10mm -13mm, if the magnetic conductive disk described in increasing in case below certainly is added along 6 additional structure, outside Diameter also needs slight increase, but on the whole, can be made small.

Of the invention is related to two concepts of magnetic conductive disk summation depth h0 and annular permanent magnets summation thickness h.Magnetic conductive disk summation Depth h0 refers to the sum of insertion magnetic conductive disk depth h01 and reception magnetic conductive disk depth h02；Annular permanent magnets summation thickness h refers to position The thickness of the first annular permanent magnets thickness h 1 in insertion element and the second annular permanent magnets thickness h 2 positioned at receiving element it With.When only in insertion element there are when annular permanent magnets, annular permanent magnets summation thickness h is exactly the first ring-type in insertion element Permanent magnet thickness h 1；When insertion element 1 and receiving element 2 are all there are when annular permanent magnets, annular permanent magnets summation thickness h is just It is the first annular permanent magnets thickness h 1 in insertion element and the sum of the second annular permanent magnets thickness h 2 on receiving element.At this In invention, in order to constitute good magnetic conduction closing structure, so carry out annular permanent magnets summation thickness h and magnetic conductive disk summation depth Cooperation.But the presence of the error due to reality, do not accomplishing annular permanent magnets summation thickness h and magnetic conductive disk summation depth h0 phase With in the case where, annular permanent magnets summation thickness h less than normal can then be more advantageous to reduction permanent magnet in magnetic conductive disk summation depth h0 Collision and the fragmentation that generates, in general, permanent magnet summation thickness h and the error of magnetic conductive disk summation depth h0 are no more than 0.2mm.

Indicated with one group of formula be exactly: h0=h01+h02;h=h1+h2；h≦h0；h0-h≦0.2mm.

Transverse shifting between insertion element 1 and receiving element 2 is prevented via the engagement of magnetic conductive disk recess portion and is loosened.? First annular permanent magnets of insertion element 1 and the second cyclic annular magnetizer of receiving element 2 generate field of magnetic forece.In operation, when slotting When entering element 1 and being arranged on close to any position of receiving element 2, annular permanent magnets 4 slide to automatically be aligned in recess portion, and Made due to the powerful field of force the first annular permanent magnets 4 and magnetic conductive disk upper bottom surface surface or the second annular permanent magnets 41 it is upper Surface completely attaches to, which attracts two elements and it is pushed medially to connect on its shared axis.

Similar to the first annular permanent magnets 4, the second annular permanent magnets 41 can be fixed to receiving element 2 by adhesive The magnetic conductive disk of magnetic conductive disk 5 try to get to the heart of a matter.However, it will be understood by those skilled in the art that can also be used other way by second it is cyclic annular forever During the magnetic conductive disk that magnet 41 is fixed to receiving element 2 is tried to get to the heart of a matter, including but not limited to (also referred to as it is press-fitted by using interference fit Close) realize combination.One in the parallel surfaces of second annular permanent magnets 41 is one with the magnetic conductive disk 5 of receiving element 2 Surface co-planar.Magnetic conductive disk edge 6 can be any shape, can add additional fixed knot on the basis of magnetic conductive disk inner hole 7 Structure.It is easily connected on sheet material 9 by suture 8.

The first annular permanent magnets 4 in insertion element 1 are directed to sliding path, into the recess portion of receiving element 2, and Corresponding second annular permanent magnets, 41 automatic aligning contact.Magnetic force can by tactile be perceived to guide positioning, and two elements It is correct engagement can by audible click or be only engagement determine.It does not need the guidance of vision and only needs most Few manual coordination is by the first annular permanent magnets 4 in insertion element 1 of the invention and the second annular permanent-magnet in receiving element 2 Body 41 is combined together.

Fig. 2 b is sectional elevation of the magnetic clasp of Fig. 2 under insertion element and receiving element attracting state.When actuation, it can see Its summation thickness is more thicker than case 1 out.If other positions are identical as 1 size of case, the general thickness of magnetic clasp 3 is about 2.4mm.Still belong to very thin button.It is slightly thinner than normal shirt button.

Embodiment 5

Fig. 5, Fig. 5 a, Fig. 5 b, Fig. 5 c and Fig. 5 d are the embodiments with the auricle structure 62 on magnetic conductive disk edge 6 with hole.

Fig. 5 is magnetic conductive disk edge of the present invention in the insertion element of the case study on implementation of the auricle with hole and putting down for receiving element Face view.Auricle with hole refers to that magnetic conductive disk edge outwardly protrudes, and digs the hole for the crescent having, so as in protrusion Suture 8 is passed through between edge and hole with fixed magnetic conductive disk borderline structure.Due to the profile of this structure likeness in form ear, so We term it auricles herein.Auricle with hole is not horizontal stretching, warpage but try to get to the heart of a matter in-plane to magnetic conductive disk Then bending tries to get to the heart of a matter what planar horizontal extended along magnetic conductive disk, minimum number is 2, because 3 points can determine a face, institute Generally to select 3 for reducing stitch points and taking into account secured consideration.

Such as when Fig. 5 each section is all identical as Fig. 1 size, the auricle structure on magnetic conductive disk edge 6 with hole is only increased When 62, the complement outside diameter of magnetic clasp 3 can achieve 14 mm -16mm.

Fig. 5 a is cut along line 5a (the 1) -5a (1) of Fig. 5 insertion element intercepted and along line 5a (the 2) -5a (2) of Fig. 5 The sectional elevation of the receiving element taken.Thus figure as can be seen that the auricle 62 with hole towards plane where the trying to get to the heart of a matter of magnetic conductive disk 5 Direction bending, in this way can be to 8 reserved space of suture when suturing.

Fig. 5 b is the insertion element of Fig. 5 and the sectional elevation of receiving element, be shown insertion element through line and Receiving element is stitched to the mode of sheet material respectively.

It is shown in such a way that insertion element 1 and receiving element 2 are stitched to sheet material 9 by line respectively.It can be with from figure Find out, since it not only has a main seam area, there are two the auxiliary seam area that auricle 62 with hole above is constituted, What button and sheet material can be docile in this way is combined together, and sheet material 9 is when encountering outside pulling force, will not around stitch points Warpage or deflection occurs.

Fig. 5 c is sectional elevation of the magnetic clasp of Fig. 5 under insertion element and receiving element attracting state.Such as figure, it is attracted Overall thickness afterwards can achieve 1.6mm.

Fig. 5 d is sectional elevation compared with taking the magnetic clasp of Fig. 5 scheme to set the relative size of porose scheme with edge.It can See, takes the magnetic clasp volume of conventional peripheral opening formula obvious big more.In contrast, magnetic clasp 3 of the invention seems small and exquisite, smart It causes, possesses higher product effect ratio.

As it appears from the above, magnetic clasp is designed to have very little thickness and can be by protrusion magnet to eliminate sliding and accidental separation Corresponding component.Using magnet itself to combine two functions to eliminate with individual joint element, and reduce thickness And reduce the complexity of construction.The magnetic element of the button is maintained as being stuck in thin soft magnetism plate (magnetic conduction pan bottom Thickness is about the half of permanent-magnet material thickness), and no longer increase overall thickness in any way, it is equal to monolithic permanent-magnet material in total 2 times of minimum economic thickness can accomplish plus the two side-seams about thickness of 1.6mm in total, this structure, having been approached can protect Demonstrate,prove the limiting value of the minimum economic thickness of fundamental strength.Its diameter can be accomplished within 12 mm, and the element is in engagement Keep hidden and imperceptible.The construction of magnetic clasp 3 allows two magnetic elements to be in direct contact with one another, to maximize coercive force.Small ruler Very little magnet can make that production cost is low, light-weight, thickness is small with the construction simplified, and product effect is than high.

In the various embodiments described above, it includes the soft magnetic materials composition of electroplated layer or coating that magnetic conductive disk, which uses surface, here institute The soft magnetic materials said refers to that magnetic conductivity is big, the big permeability magnetic material of easy magnetization, saturation induction density.Including pure iron, martensite is not Become rusty steel, silicon steel, permalloy, ferrocobalt, iron-nickel alloy etc..

Two magnetic conductive disks fasten, and annular permanent magnets are included therein, thus form closed magnetic inside two magnetic conductive disks Road, and the magnetic conductive disk of above-mentioned material to annular permanent magnets carry out magnetic conduction during, through the excessive magnetic line of force of magnetic conductive disk Largely decayed, so magnetic screen can be played the role of again simultaneously.

Magnetic conductive disk of the present invention generally uses Sheet Metal Forming Technology to process, so based on malleable metal or metal alloy, It should be avoided and use fragile material.

Annular permanent magnets of the invention are made of permanent-magnet material.Permanent-magnet material mentioned here, also known as hard magnetic material are Refer to that coercivity is big, remanent magnetism is big, the big magnetic material of the area of hysteresis loop.For the big attraction applied by small size, It is advantageous to the constituent materials that Nd-Fe-B permanent magnet makees annular permanent magnets.Because it has small in size, light-weight and magnetic strong Feature is the magnet that the ratio of performance to price is best so far.Wherein sintered NdFeB --- sintered Nd-Fe-B permanent magnet passes through gas It is smelted after stream powder-grinding, coercivity value is very high, and possesses high magnetic property.The mechanical performance of itself also quite it It is good, shape and drilling that can be different with cutting processing.Be well suited for annular permanent magnets come using.Neodymium iron boron is divided according to magnetic energy product, About following model: N30-N52.Label is higher, and cost is higher, in general, being designed based on good structure, medium size Magnetic clasp selection the lower such as N35 of label NdFeB material be also sufficient for sb.'s need.Meanwhile other hard magnetic materials, such as iron Oxysome, Al-Ni-Co series permanent-magnet alloy, siderochrome cobalt system permanent-magnet alloy, permanent-magnet ferrite, rare earth permanent-magnetic material and composite permanent-magnetic material Deng be also alternatively, although we say below mainly Nd-Fe-B permanent magnet material, other materials application and design Also similar therewith.Neodymium iron boron strong magnets are as third generation rare earth permanent-magnetic material, with the very high ratio of performance to price, but the disadvantage is that Frangible, so a place's shell that consider package to be had in structure design, second does not limit when being magnet absorption to be avoided, and causes Make to be crushed because frequently hitting.Third, so to there is the shielding construction of high-intensity magnetic field, makes exposed magnetic field because its magnetic field is more powerful By dying down by force.4th, there is antirust coat.

The cost of permanent-magnet material, in general, volume is smaller, cost is lower.But small in size, suction can also die down, Er Qiehou Spend it is small to a certain extent when, since material itself is more crisp, processing get up will be more and more difficult, the requirement to equipment will be got over Carry out higher, the especially NdFeB material of processing annular specific shape in this way, performance becomes apparent.At this moment, cost is with volume Reduction and the curve of reduction will appear inflection point, then, we can be cost-volume curve inflection point of this specific shape Thickness is known as minimum economic thickness, and, when producing magnetic clasp, for cost performance consideration, the thickness of general magnet is higher than minimum for we Economic thickness.Minimum economic thickness is a benchmark of magnetic clasp integral thickness, it can be measured in magnetic button structure design in thickness Otherwise superiority and inferiority in terms of index disregards the scheme of cost just without comparativity, to can not compare the superiority and inferiority of scheme.Generally , in the present invention, the thickness of the magnetic conductive disk half thick and heavy using annular permanent magnets, for example the minimum economic thickness of permanent magnet is 0.8mm, then the thickness of magnetic conductive disk can use 0.4mm, the thickness of magnetic clasp entire in this way includes the package structure of sewing thread, always Total 1.6mm can.And the general thickness of magnetic clasp generally will at least reach the minimum economic thickness of permanent magnet in the prior art 4 times, such as 3.2mm.Obviously, structure of the invention design shows more outstanding in this index of thickness.

In the present invention, annular permanent magnets and magnetic conductive disk design have corresponding cladding or coating, and can have different Color plays antirust and decoration function.Pattern abundant depends primarily on antirust decorative layer.Because some will be made into bright button, With the conjunction matching in colour of clothes, so magnetic clasp will have the needs of various patterns.Nd-Fe-B permanent magnet have lot of advantages, but due to Its content of material is easy to cause corrosion, so must carry out different coating treatments to surface according to different requirements, for example plates Nickel, zinc-plated, nickel-clad copper nickel composite deposite is gold-plated, plating epoxy resin etc..

The composite can be widely applied to clothes, underwear, leatherware, shoes, luggage, with being decorated with composition fastening/opening system, Wherein, especially clothes, luggage and accessory are even more its typical application.For clothes, the application of magnetic clasp of the present invention, Not only wear off it is more convenient, and because it does not need buttonhole, can by it is traceless change button suture location, to adjust It is whole elastic, to be allowed to more fit.Or by the way of one-to-many, as an insertion element corresponds to the actuation of multiple receiving elements Position or an opposite receiving element correspond to the attracted position of multiple insertion elements, to achieve the purpose that adjustment is elastic.For Luggage, such as similar to the wallet of cortex or silk fabrics material, the magnetic clasp of superthin structure is very applicable in the present invention.For clothing Decorating fittings, the especially ornaments containing soft fabric material, such as silk scarf, justice neck, corsage, the present invention be all it is suitable, can It very easily wears/takes.

Magnetic clasp of the present invention is illustrated above by reference specific embodiment, however to those skilled in the art can be right The present invention carries out various modifications and changes without departing from the spirit and scope of the invention, the range only by the attached claims and Its law equally limits, without being limited by given example.For example, the shape of magnetic conductive disk can be different from shown in example, Magnet uses the material different from neodymium iron boron.Magnetic conductive disk can be made of different soft magnetic materials, and have different from shown in Also adhesive or other retention mechanisms can be used to be fixed to sheet material come the line instead of pass through hole for size.Therefore, shown and institute The example of explanation is only to illustrate, rather than limit.

Change it should be understood that carrying out details to many aspects of the invention without departing from the scope of the present invention.Furthermore.Before state The bright purpose for being only used for signal, and it is not used in the purpose of limitation, but limited by claim of the invention.
