Embodiment

Below, with reference to description of drawings best form of implementation of the present invention.

Fig. 1 shows the perspective view after the magnetic fixed fastening assembling of the present invention.As shown in the drawing, magnetic fixed fastening of the present invention is made of a pair of first assembly and second assembly.Each assembly of these assemblies is as mentioned below, is fixed on either party of a pair of corresponding component (for example body of handbag and lid) of the object (for example handbag) that uses this magnetic fixed fastening according to direction shown in the diagram respectively.These assemblies are under the effect of the magnet that is arranged at first assembly, combinations of directions (the arrow Ren of Fig. 1, mouthful direction) along first assembly and second assembly, with adsorption plane 31,67 (as Fig. 3 of back is represented) each other, attract each other and combine, keep the closure state of the corresponding component of object by this combination.Utilize this magnetic fixed fastening, the combination of its first assembly and second assembly is to automatically lock when being subjected to the magnet effect.This locking can be removed simply by operating second assembly.

Fig. 2 is the decomposition diagram of above-mentioned each assembly, in addition, and the profile of the center line of the magnetic fixed fastening of the present invention when Fig. 3 shows these combination of components.By these accompanying drawings, can find out the detailed structure of the component parts that constitutes each assembly in more detail.Below mainly describe each component parts in detail with reference to Fig. 2.

At first, first assembly is described.

As Fig. 2 left side is represented, first assembly by annular plate 10, be fixed on holding member 14, magnetic on this annular plate 10 and be adsorbed on ringshaped magnet 22 and cylinder sleeve 26 on this annular plate 10, cover the lid 30 of this magnet 22 and annular plate 10 and pass the center of first assembly and the engagement pin 34 that is provided with constitutes.But as mentioned below, annular plate 10 can omit.

Annular plate 10 can be a magnetic, for example the iron of ferromagnetism body.Therefore, annular plate is subjected to the influence of magnet.Component parts with description is same, and its material resemble the annular plate uses under the situation of iron, in general, for purpose antirust and decoration, electroplate.Set hole 12 is that the engagement pin 34 of back passes and the hole of using at the center of annular plate 10.

Holding member 14 is fixed on the one side of annular plate 10.As its fixing means, can use welding such as for example spot welding, solder, soldering, riveted joint waits other suitable methods.Adopt the more fixedly spot welding of holding member 14 and riveted joint in the present embodiment.What 4 points 15 among the figure shown in the dotted line were represented is the puddle that spot welding produces.The position of these puddles is that the mode of equalization equally spaced evenly separates along same circumference substantially with the power on the holding member of affacting.In addition, in the present embodiment, holding member 14 also can be not separated with annular plate 10, and integrally formed.There is no particular limitation for the material of holding member, and still, if holding member and annular plate are integrally formed, nature is identical with the material of annular plate.In addition, holding member 14 is also keeping the effect as annular plate 10.When magnet 22 was plastic magnet, either party or two sides of annular plate 10 or holding member 14 also can be integrally formed with plastic magnet, also can be integrally formed with the opposing party's parts.Also can be by being threaded or riveting or additive method such as welding is installed in parts on these another parts.And this plastic magnet also can be electroplated.

Two standing parts 18 that holding member 14 extends downwards by annulus 16 with from the both sides of this annulus 16 are formed.Annulus 16 is used for fixing on the annular plate 10, and on the other hand, standing part 18 is used for first assembly is fixed to object.At the central part of annulus 16, be provided with and annular plate 10 big or small essentially identical holes 20.Holding member 14 is when permutation is arranged each other with annular plate 10, and the hole 20 of this annulus 16 also is arranged in permutation with the hole 12 of annular plate 10, thus, forms and is suitable for the permutation hole that engagement pin 34 passes.

Ringshaped magnet 22 is installed on the surface of annular plate 10 of an opposite side of holding member 14 installation sides.The external diameter of magnet 22 makes less than the external diameter of annular plate 10 proper because of following reason.This magnet 22 is the permanent magnets that are respectively equipped with any one utmost point of the N utmost point or the S utmost point on the table the inside.Thereby magnet 22 is under the effect of self magnetic force, and magnetic is adsorbed on the annular plate 10.When magnet 22 magnetic were adsorbed on the annular plate 10, annular plate 10 had magnetic under the effect of magnet, the result, and annular plate 10 itself also produces magnetic force.This magnetic force of annular plate 10 has the function of the particular importance that is suitable for adsorbing cylinder sleeve 26.In addition, magnet 22 can be neodium magnet, also can be other magnet.The thickness of magnet is approximately 0.5mm～10mm, but its thickness can freely design, and these magnet also can be electroplated.

Cylinder sleeve 26 is installed on the surface with the annular plate 10 of magnet 22 same side.In the present embodiment, cylinder sleeve 26 is configured near the central part of annular plate 10, and still, cylinder sleeve 26 also can be configured in the position that the central part with annular plate 10 staggers.When cylinder sleeve 26 was configured near the central part of annular plate 10, cylinder sleeve 26 directly was configured on the annular plate 10 under the state that the mesopore portion 24 with magnet 22 separates.But cylinder sleeve 26 does not need to separate with magnet 22, and it also is feasible contacting with magnet 22.In other words, if annular plate 10 is not set, under the annular aperture state of contact of cylinder sleeve 26 and magnet 22, will also be feasible in cylinder sleeve 26 these annular aperture of embedding directly.In this occasion, can save annular plate 10.When magnet 22 is plastic magnet, also can be integrally formed with cylinder sleeve 26.In addition, also can adopt to be threaded or additive method such as riveted joint, annular plate 10 or holding member 14 both sides are installed on the cylinder sleeve 26, can also among both be installed on another.

Cylinder sleeve 26 is the same with annular plate 10, is formed by magnetic.Thereby cylinder sleeve 26 magnetically is adsorbed on the annular plate 10 that has magnetic.Clearly, when cylinder sleeve 26 magnetically was adsorbed on the annular plate 10, cylinder sleeve 26 had magnetic equally with annular plate 10, the result, and cylinder sleeve 26 self also produces magnetic force.This magnetic force of cylinder sleeve 26 plays the critical function of the following engaging part 56 of absorption.And cylinder sleeve 26 also can be integrally formed with annular plate 10.

When cylinder sleeve 26 magnetically was adsorbed on the annular plate 10, near the most advanced and sophisticated top from magnet 22 of cylinder sleeve 26 was outstanding.In other words, cylinder sleeve 26 from the adsorption plane 31 of first assembly towards outstanding to the outside with the direction of second combination of components (Fig. 1 from arrow Ren direction).On this cylinder sleeve 26, also be provided with and the hole 20 of holding member 14 or the hole 12 big or small essentially identical through holes 28 of annular plate 10 along its length direction.When cylinder sleeve 26, annular plate 10 and holding member 14 all were arranged in permutation, the hole by separately formed engagement pin 34 and passes employed permutation hole.

Lid 30 relative magnet 22 and annular plate 10 are installed with.The shape of lid 30 is annulars.In addition, lid 30 size makes the size of the side of except the bottom nearly all of can just in time cover magnet 22 and annular plate 10.As indicated above, in the present embodiment, under situation about the external diameter of magnet 22 being set for less than the external diameter of annular plate 10, the edge of lid does not need corner angle, thereby this edge can make beautiful smooth curved surface.When lid 30 covers magnet 22 and annular plate 10,, side-prominent downwards from the bottom surface of annular plate 10 along formed 5 stators 32 that extend downwards of the bottom side circumferential part of lid 30.Inwards crooked this stator 32 along the bottom surface of annular plate 10, thus, under the state that magnet 22 and annular plate 10 become one, lid 30 is fixed with respect to magnet 22 and annular plate 10.There is no particular limitation for the material of lid, still, uses for example such nonmagnetic substance of brass in this structure.The purpose that this lid 30 is set is in order to protect magnet 22 and annular plate 10, in addition, also to make combination between the two more firm.But, also can save this lid 30.In addition, the external diameter of magnet 22 can be less than the external diameter of annular plate 10, also can be greater than the external diameter of annular plate 10.Undoubtedly, there is no particular limitation for the shape of magnet 22.But, cover at 30 o'clock not being provided with, combine more firmly in order to make between magnet 22 and the annular plate 10, preferably adopt adhesives and other methods to fix.Be provided with under 30 the situation covered, with the face of adsorption plane 67 (with reference to Fig. 1, Fig. 3) absorption of second assembly for covering 30 front side 31.On the other hand, be not provided with under 30 the situation covered, with the face of second assembly absorption be the front side 21 of covering the magnet 22 of 30 lower positions.In addition, be provided with under 30 the situation covered, cylindric sleeve 26 also from the adsorption plane 31 of first assembly towards outstanding to the outside with the direction (the arrow Ren direction of Fig. 1) of second combination of components.

Engagement pin 34 is arranged to insert the state in the formed permutation hole, each hole of cylinder sleeve 26 or annular plate 10 and holding member 14.Engagement pin 34 by pillar 36, be arranged at 38 of these pillar 36 tops and constitute.When inserting in the permutation hole, the part of pillar 36 of having only engagement pin 34 is by this permutation hole, and 38 part is by this permutation hole.

The length of the pillar 36 of engagement pin 34 is longer than the total length in the formed permutation hole, hole of cylinder sleeve 26 grades.Therefore, when the pillar 36 of engagement pin 34 passed the permutation hole, near the hole 20 from the holding member 14 of the bottom side that forms this permutation hole pillar 36 most advanced and sophisticated was outstanding.Rivet with respect to the bottom surface of holding member 14 by protuberance (not shown) this pillar 36, perhaps adopt other suitable methods such as weld, be threaded that the protuberance of this pillar 36 is fixed with respect to holding member 14, thus, also can be fixing with respect to annular plate 10 or cylinder sleeve 26 engagement pin 34.In addition, when engagement pin 34 was fixed on these parts, near the most advanced and sophisticated bottom surface with respect to holding member 14 of the pillar 36 of engagement pin 34 flushes, and was perhaps outstanding a little from this bottom surface.

When engagement pin 34 passed the permutation hole, 38 of this engagement pin 34 exposed towards the outside from the top of cylinder sleeve 26.At least this part of 38 is formed by nonmagnetic substance, thereby, be not subjected to the influence of magnet.As mentioned below, when first assembly and second combination of components, this 38 central part that passes second assembly, but, as indicated above, because this is not subjected to the influence of magnet, thereby, this can magnetic not be adsorbed onto on arbitrary part of second assembly, hinders the combination operation of first assembly and second assembly.In addition, the part beyond this is that pillar 36 can be magnetic or nonmagnetic material.Engagement pin 34 38 on the inclined plane is set purpose be, even in 38 occasion that contact with the snap-latch piece 65 of slide block 56, the frictional resistance that also can make each other to be produced diminishes, thereby snap-latch piece 65 is moved glossily, makes 38 to be easy to insert in the permutation hole of second assembly.

Description second assembly.

Shown in Fig. 2 right side, second assembly by skirt 66, be contained in stiffener 80 in this skirt 66, and this stiffener 80 between form spatial accommodation hold parts 40, be clamped in stiffener 80 with moving about and hold the slide block 56 in the parts 40 formed spatial accommodations and be fixed on the holding member 48 that holds on the parts 40 and constitute.

The ferromagnetism body (magnetic) of skirt 66 usefulness such as iron forms, and be proper.Has following cited excellent results by forming with magnetic.The first, when first assembly and second combination of components, the magnetic force that is produced by first assembly can affact on the skirt 66.In other words, the magnetic force of first assembly thus, can produce stronger absorption affinity not only to slide block 56, skirt 66 is all had effect between first assembly and second assembly.The second, when first assembly and second combination of components, skirt 66 has the function of yoke, and the motion of slide block 56 is successfully carried out.In addition, when skirt 66 is formed by other nonmagnetic materials such as plastics, brass, can obtain the above-mentioned latter's effect.This point will be narrated hereinafter.

Skirt 66 is integrally formed by relatively thinner flat metal plate being carried out punching press, bending, pull and stretch etc.By adopting this manufacture method, can reduce manufacturing expense, still, and might not be integrally formed, also can adopt other manufacture methods.For example, the structure that cylindric guide 69 and skirt 66 or other parts are arranged to separate, and then to be installed together also be feasible.In addition, replace on skirt 66, being provided with the structure of guide 69, also can hold the parts that the formation of parts 40 1 sides is equivalent to guide 69.The part of guide 69 parts of guide (or with respect to) is set on skirt 66 and two sides that hold parts 40, and then it is combined, it also is feasible forming complete guide.Certainly, the designer can freely select the material or the manufacture method of skirt 66.

It is guide 69 and the front wall section 70 tripartite frameworks (frame) that surround that skirt 66 makes by outer wall section 68, inner wall section.Though from figure, can not find out significantly,, in the front of skirt 66 (adsorption plane), promptly the front of front wall section 70 forms the flat condition structure, and does not form the described cyclic lug of conventional art.The adsorption plane 67 that adsorb as the adsorption plane 31 with first assembly this front (face of an opposite side (paper side) of represented face among the figure).

It is that guide 69 is more noticeable that inner wall section is set.Guide 69 makes the cylindrical shape roughly with certain internal diameter, and, from direction (direction of the arrow mouth of Fig. 1) the opposite direction of adsorption plane 67 (with reference to Fig. 1, Fig. 3) court, extend to the internal holes of second assembly with first combination of components.Guide 69 is set mainly contains following 3 meanings.The first prevents the transversion malposition between first assembly and second assembly.If when first assembly and second combination of components or after its combination, can not produce transversion malposition between the two fully or can not produce any dislocation, just not need expressly to be provided with this guide 69.But, in fact producing big dislocation through regular meeting, this dislocation impairs the magnetic fixed fastening good action.

First meaning that guide 69 is set is to address this problem.That is to say, in the time of can preventing first assembly and second combination of components or after its combination, the transversion malposition that between this first assembly and second assembly, is produced.With reference to Fig. 3, describe more specifically, by guide 69 is set on second assembly, can be along guide 69 inboard formed holes 71 38 of the engagement pin of first assembly be directed into the inside of second assembly, after this head is led, just can prevent that head from producing horizontal dislocation in second component internal, for example, pushing slide block 56 is when unlocking, and the power that produced this moment is along transversal thrust skirt 66, can avoid

hole

71 and 38 dislocation thus.

Second meaning that guide 69 is set is to strengthen the intensity of skirt 66 above-below directions.As mentioned below, second assembly is crooked respectively the standing part 54 that is fixed in the holding member 48 that holds on the parts 40, impact with tup etc. then, be fixed on the objects such as handbag, in this fixed operation, near holding member 48, in other words, near the center that holds parts 40 and skirt 66, acting on sizable power along the vertical direction.This power is possible destroy the very big power of holding parts 40 and skirt 66 (i.e. second component body) or making its distortion.Especially in the present embodiment, under the situation that the more weak thin plate of skirt 66 usefulness strength ratios forms, skirt 66 (second component body) is easy to be destroyed or produce distortion in this operation, cause the slide block 56 that is held not move about out.Therefore, the present invention is provided with guide 69 near the center of skirt 66, and, also be provided for strengthening the reinforcement guide 82 of the stiffener 80 of this skirt, therefore, strengthened its intensity, solved this problem.

It is relevant with grooving portion 72 set on the part of guide 69 that the 3rd meaning of guide 69 is set.This grooving portion 72 is used to make slide block 56, and particularly the holding section 65 of slide block 56 is near the inboard of guide 69, in other words, makes the magnetic cylinder sleeve 26 of first assembly that this holding section 65 disposed near guide 69 inboards, and it is adsorbed.The size of this grooving portion be holding section 65 by the time needed sufficient size.On the contrary, the part of guide 69 beyond grooving portion 72 is continuous.The 3rd meaning that guide 69 is set is, the part beyond this grooving portion 72, and magnetic force can not act on the slide block 56.In other words, guide 69 has the function of the part beyond the holding section 65 of slide block 56 being carried out magnetic seal.

In order to give full play to the effect of above three kinds of meanings, guide 69 is arranged on the angular range greater than 180 degree at least, for example approximately is arranged on the angular range of 240 degree in the present embodiment.This angular range is, by means of the magneticaction on the holding section 65 that affacts slide block 56, can fully be adsorbed on slide block 56 on first assembly, simultaneously, when first assembly and second combination of components or after the combination, the transversion malposition that can prevent from each other to be produced, and can strengthen the intensity of the above-below direction of skirt 66 again.If this angular range for example is taken at the following angular range of 180 degree, 38 of engagement pin 34 will expose from guide 69, does not have the effect as guide 69, and, can not keep full intensity.But the designer still can freely select the following angular range of 180 degree however.In addition, a cylinder sleeve 26 on the length of guide 69 and first assembly and the second combination of components direction and 38 a formed same length.Its internal diameter is bigger slightly than 38 external diameter.But, the length of guide 69, internal diameter can freely design.

Stiffener 80 has the function of strengthening skirt 66.In other words, stiffener 80 is only used for strengthening skirt 66 and is provided with, thereby can omit.Stiffener 80 is contained in this skirt 66 with the rear portion of opening wide of illustrated direction from skirt 66.

Stiffener 80 is same with skirt 66, and integrally formed by thin metal plate is carried out punching press, pull and stretch, bending etc., but, integrally formed is not necessary, and it also is feasible adopting other manufacture methods to make same shape.Employed sheet metal also can be identical with skirt 66, in addition, can also form with skirt 66 essentially identical operations.In this occasion, manufacturing expense is very low, and is still the same with skirt 66, not necessarily integrally formed, and, also can form with nonmagnetic material.

Stiffener 80 has the shape and the size of the particularly front wall section 70 that is suitable for strengthening skirt 66 and the intensity of inner wall section (being guide 69).That is to say, stiffener 80 have the body part 81 that be roughly annular corresponding with the front wall section 70 of skirt 66 and with the guide 69 of skirt 66 corresponding from body towards upper and lower to the reinforcement guide 82 that extends.

When stiffener 80 was contained in the skirt 66, the whole inboard that the body part 81 of stiffener 80 is covered with the front wall section 70 of skirt 66 substantially was, the face of the opposite side of adsorption plane of skirt 66.When stiffener 80 was received in the skirt 66, set protuberance 83 embedded in the set grooving portion 73 in outer wall section 68 relevant positions of skirts 66 on the periphery of body part 81.Chimeric by this protuberance 83 and grooving portion 73, stiffener 80 is contained in the skirt 66 according to given direction, and in addition, after stiffener 80 was contained in the skirt 66, stiffener 80 was keeping with given direction with respect to skirt 66.

Strengthen guide 82 and be arranged on for example about 180 degree angular ranges littler than the guide 69 of skirt 66, still, identical with the angle of guide 69 also is feasible.The height setting of strengthening guide 82 becomes: in the time of in stiffener 80 is contained in skirt 66, lower or identical than the height of the guide 69 of skirt 66.But, under the situation of setting the height that is lower than guide 69 for, form step 84 (with reference to Fig. 3) by means of this relation of strengthening guide 82 and guide 69.This point will be narrated hereinafter.From the relation of the angular range of strengthening guide 82 and the angular range of the guide 69 of skirt 66 as can be seen, in the full week that reinforcement guide 82 can not surround the guide 69 of skirt 66, still, has the function that to strengthen skirt 66 fully.In addition, the angular range of strengthening guide 82 is taken as full week of guide 69 of skirt 66 even bigger angular range is fine, and still, in this case, can't guarantee the holding section 65 employed grooving portion of slide block 56.On the other hand, from the relation of the height of strengthening guide 82 and the height of the guide 69 of skirt 66 as can be seen, when stiffener 80 is contained in the skirt 66, by means of this guide 69,82, the step 84 of formation above-below direction as shown in Figure 3.The step 84 that forms by two guides constitute with hold parts 40 on the set complementary mutually shape of step 47.As mentioned below, by disposing this step 84,47 accordingly, can form gapless substantially permutation hole, simultaneously, in fact also prolonged guide 69 formed holes, and improved its intensity.

Stiffener 80 is ferromagnetism bodies (magnetic) of iron and so on, like this, can obtain hereinafter described the various effects relevant with skirt 66.Iff being for the intensity that strengthens skirt 66 stiffener 80 to be set, these stiffener 80 usefulness nonmagnetic materials form, and also can obtain same purpose.But, be to be adsorbed function or yoke function if utilize stiffener 80 for what strengthen skirt 66, then stiffener 80 is formed proper by magnetic.That is to say, by forming stiffener 80 with magnetic, when first assembly and second combination of components, the magnetic force of first assembly not only acts on slide block 56 and the ring-shaped article 66, and act on the stiffener 80, thereby between first assembly and second assembly, produce stronger absorption affinity, and, the yoke function of the magnetic force that is produced with respect to first assembly by means of the stiffener 80 that affacts on the skirt 66 can make the motion of slide block 56 more smooth.This effect is as mentioned below, also can obtain under the situation that stiffener 80 or skirt 66 are formed by nonmagnetic material, still, under the situation that skirt and stiffener 80 both sides are formed by magnetic, can obtain bigger effect.

When slide block 56 is suitable for first assembly and second combination of components, to automatically locking between the two.In other words, when first assembly and second combination of components, under the magnetic action that particularly its cylinder sleeve 26 is produced of first assembly, slide block 56 is moved on first assembly, absorption in the above.This suction-operated is the locking action between first assembly and second assembly just.

In order to cut down manufacturing expense, in the present embodiment, slide block 56 is integrally formed by punching press, bending, pull and stretch etc., but is not must be integrally formed, also can adopt other manufacture methods.This point is identical with skirt 66 or stiffener 80.At last, slide block 56 is made about the basic structure of symmetry roughly for key shape (other shapes also can).When first assembly and second combination of components, set cylinder sleeve 26 passes near set hole 64 slide block 56 centers around the engagement pin 34 of first assembly and this engagement pin, thereby is in place.

Slide block 56 is provided with body part 61 and shank portion 60.Body part 61 is provided with outstanding to the inside holding section 65.Holding section 65 is adsorbed on set cylinder sleeve 26 around the engagement pin 34 of first assembly when first assembly and second combination of components, play the important function that automatically locks above-mentioned these assemblies.These holding section 65 integral body roughly make crescent shaped (other shapes also can), and form the corresponding flat inclined plane of part with 38 attenuation of the engagement pin 34 of first assembly in its end, and certain, it also is feasible not forming this inclined plane.The shape of holding section 65 is corresponding with the shape of engagement pin 34, and like this, when first assembly and second combination of components, even 38 the contacting of holding section 65 and engagement pin 34, the frictional force between them also can diminish.In addition, the relatively absorption of cylinder sleeve 26 is to carry out near the tip on the inclined plane of holding section 65.On the other hand, shank portion 60 is used for the holding section 65 that is adsorbed on the cylinder sleeve 26 is drawn back from first assembly, unlocks etc.

Slide block 56 is configured on the stiffener 80 that is contained in the skirt 66, and its body part 61 covers from upside by holding parts 40.As shown in Figure 3, be formed for installing the space 49 of slide block 56 in holding parts 40, the body part 61 of slide block 56 places in this space 49.On the other hand, the shank portion 60 of slide block 56 exposes to the outside by the set portion 42 of cutting of the outer wall section that holds parts 40.Afterwards, be contained in the skirt 66 holding parts 40, this situation with stiffener 80 is identical, from hold parts 40 outstanding cut corresponding set grooving portion 73 on the outer wall section 68 that portion 42 embeds skirts 66, thus, can be according to given towards being contained in the skirt 66 holding parts 40, when holding after parts 40 are contained in the skirt 66, just can hold parts 40 with respect to skirt 66 with given towards maintenance.When holding parts 40 and being contained in the skirt 66, slide block 56 have only shank portion 60 from hold parts 40 with stiffener 80 formed spatial accommodations, hold that parts 40 go out portion 42 with skirt 66 each sections and grooving portion 73 exposes, and the body part 61 with holding section 65 is contained in the spatial accommodation with moving about.In addition, from the shape that cuts portion 42 and slide block 56 of holding parts 40 etc. as can be seen, the swimming direction of slide block 56 is the direction vertical with set grooving portion 73 on the outer wall section 68 that holds parts 40 and skirt 66, the just length direction of slide block 56 (the arrow B direction of Fig. 3).

After holding parts 40 and being contained in the skirt 66, from outstanding 6 stators 74 of the outer wall section 68 of skirt 66 to holding the bending respectively of parts 40 corresponding cut-out portions 41.Thus, be fixed on the skirt 66 holding parts 40.

Slide block 56, particularly its holding section 65 in the spatial accommodation, under the situation of lever 60, its position can freely change.Thereby holding section 65 can not be under the state of any adhesion in spatial accommodation, even be absorbed in this state, by making the shank portion motion, just can remove this state simply.The motion of the holding section 65 response shank portions 60 of slide block 56, set grooving portion 72 on the guide 69 by skirt 66, with the inboard (in other words, the cylinder sleeve 26 of magnetic first assembly) of this guide 69 by the inboard that is configured in this guide 69 near to or in contact with or with it away from.But, with respect to approaching, the absorption of cylinder sleeve 26, be under the effect of cylinder sleeve 26 magnetic, to form naturally, thereby, originally being intended to of shank portion 60 is set, make holding section 65 away from this cylinder sleeve 26.Operation is simple owing to this slide block 56, and therefore, the tip of shank portion 60 forms handle 62 by bending or pull and stretch.

Because the magnetic action of first assembly, slide block 56 can be formed by magnetic or nonmagnetic material.In the component parts of second assembly, the holding section of having only slide block 56 65 that must form by magnetic.Slide block 56 when integrally formed, plates magnetic by nonmagnetic material on holding section 65, perhaps form holding section 65 with magnetic material, perhaps adopts additive method that holding section 65 is made magnetic in fact.In the not integrally formed occasion of slide block 56, be not that its integral body all needs to make magnetic, only the holding section 65 usefulness magnetics that are adsorbed on first assembly are formed, other parts form just passable separately with nonmagnetic material.In addition, according to designing requirement, also can or on the both sides shank portion be set on either party of holding section or body part 61, by moving of this shank portion, pushing or this holding section of tractive make holding section 65 away from cylinder sleeve 26.Any design, the designer can freely select.In the present embodiment, under the situation that slide block 56 integral body form with magnetic, should arouse attention.Its reason is, the whole slide block 56 that forms by magnetic, and the entire portion except that the holding section might be pulled on first assembly.Part beyond the holding section is pulled can be caused the holding section not lock or to move can not to carry out smoothly.Therefore, for holding section 65 is adsorbed onto on the cylinder sleeve 26 more reliably, must use one's brains.Here, in set hole, the center of slide block 56, promptly give prominence near the direction in hole towards a side of the cylinder sleeve 26 of configuration first assembly holding section 65 of slide block 56, and, part beyond the holding section, particularly the part of holding section 65 opposite sides towards away from a side of the cylinder sleeve 26 of first assembly promptly away from the direction in hole, deeper grooving is in slide block 56.As indicated above, slide block 56 be about basic symmetrical structure, and only move along its length direction, thereby, by this shape, can make the magnetic force that acts on the holding section 65 greater than the magnetic force on the part that acts on beyond the holding section 65.Magnetic seal effect by means of the guide 69 of the structure of this holding section 65 and above-mentioned skirt 66 is produced can be adsorbed on holding section 65 on the cylinder sleeve 26 of first assembly reliably.But the grooving on the slide block 56 is not necessary usually, according to circumstances, only under the magnetic seal effect of guide 69, can be adsorbed on holding section 65 on the cylinder sleeve 26 reliably yet.And the design of holding section or shank portion or slide block is arbitrarily.

Holding member 48 is fixed on and holds on the parts 40, and its shape is basic identical with the holding member 14 that is fixed on the annular plate 10.That is to say that two standing parts 54 that holding member 48 extends upward by annulus 52 with from the both sides of this annulus 52 constitute.Annulus 52 plays a part to be fixed to and holds on the parts 40, and standing part 54 is used for second assembly is fixed to objects such as handbag.Further, holding member 48 is same with the holding member 14 that is fixed on the annular plate 10, can be with to hold parts 40 integrally formed.But, being fixed on the hole 50 of the holding member 48 that holds on the parts 40, its size varies in size with the hole 20 of being fixed in the holding member 14 on the annular plate 10.Be fixed on the hole 50 of the holding member 48 that holds on the parts 40, also also nonessential, can omit.But be provided with under the situation in this hole, its advantage is that afterwards engagement pin 34, particularly its part of 38 is contained in this hole, can make the thickness when making up first assembly and second assembly more thinner.

By above having narrated the effect of holding parts 40.Undoubtedly, its material can be magnetic or nonmagnetic material.No matter be that a kind of material, can both reach the function of holding parts 40.Hold parts 40 and be provided with cyclic lug 43 towards the outside, and, around this protuberance 43, also be provided with annular recessed portion 45.This protuberance 43 is positioned at the given position that holds parts 40 with recess 45 with holding member 48, and, make the fixing simple of holding member 48.That is to say, as Fig. 1 to Fig. 3 expresses, holding member 48 is fixed on when holding on the parts 40, the hole 50 of holding member 48 is enclosed within on the protuberance 43 that holds parts 40, and, the annulus of holding member 48 52 embed with the recess that holds parts 40 45 of these annulus 52 corresponding shape settings in, then, the outside riveted joint of protuberance 43, thus, reliably holding member 48 is fixed to the given position that holds parts 40 towards the hole 50 of holding member 48.

As indicated above, hold parts 40 and be provided with the circular step 47 corresponding with the formed step of the guide 69 of skirt 66 84.These

step

84,47 shapes are complementary shape substantially, by it is meshing with each other, can improve the intensity of above-below direction.In addition, by means of this engagement, can also make the hole 46 that holds parts 40 and the guide 69 inboard formed holes 71 of skirt 66 be arranged in permutation reliably.When these holes permutations are arranged, can not form the gap basically each other, thereby when first assembly and second combination of components, first assembly is 38 can not being tangled of engagement pin 34 particularly, and the combination between the assembly is carried out smoothly.

Lock out action when hereinafter mainly first assembly and second combination of components being described with reference to Fig. 3.

The combination of first assembly and second assembly is to finish by the magneticaction between several parts of first assembly and second assembly.First assembly and second assembly be approaching mutually, shorten to a certain degree apart from the time, under the magneticaction between the slide block 56 and first assembly, perhaps when skirt 66 and stiffener 80 are formed by magnetic, under the magneticaction between slide block 56, skirt 66, stiffener 80 and first assembly, can make the instantaneous sandwich that is combined as of these assemblies.

When first assembly and second combination of components, the front 31 of the lid of first assembly (front 21 that is meant magnet when covering is not set) is attached together with the front of the skirt 66 of second assembly, simultaneously, outstanding engagement pin 34 and cylinder sleeve 26 are inserted into the inside in the permutation hole of second assembly from the top of first assembly.Meanwhile, 38 circumferential part of engagement pin 34 arrives near the tip of guide 69 of skirt 66 of second assembly, and the tip of cylinder sleeve 26 passes completely through the airtight spatial accommodation that holds between parts 40 and the skirt 66.

This magnetic fixed fastening can automatically lock the combination between the assembly in first assembly and second combination of components.Automatically the locking of carrying out is correctly said, is that the common magneticaction between magnet 22, cylinder sleeve 26, skirt 66 and the holding section 65 is realized, and mainly is the magneticaction realization between cylinder sleeve 26 and the holding section 65.On cylinder sleeve 26, produce the magnetic action that magnet 22 is caused by annular plate 10.As a result, be positioned near the slide block 56 the cylinder sleeve 26, particularly its holding section 65 is attracted on the periphery of the cylinder sleeve 26 that has magnetic.When the holding section 65 of slide block 56 is adsorbed on the cylinder sleeve 26, the permutation hole of second assembly narrows down because of this holding section 65, the result, even the combination of first assembly and second assembly is lax, because 38 the inside of holding section 65 and engagement pin 34, particularly holding section 65 and engagement pin 34 is in contact with one another and combines.Therefore, can not remove this combination.That is to say that first assembly and second assembly automatically lock together.About this point, will be described in detail with reference to Fig. 4.

Also to narrate the effect of competence exertion when having only skirt 66 or stiffener 80 to form and here, as the function of yoke by magnetic.Clearly, make by above-mentioned magnetic action under the situation of first assembly and second combination of components, produce the magnetic that magnet 22 causes of first assembly on the skirt 66 of second assembly or the stiffener 80, slide block 56 not only is pulled on the cylinder sleeve 26, but also be pulled on skirt 66 or the stiffener 80, as a result, the holding section 65 that perhaps can produce slide block 56 can not successfully be adsorbed on the query on the cylinder sleeve 26.But,, in other words,, so can overcome this problem because they have the function as yoke because skirt 66 or stiffener 80 are formed by ferromagnetism bodies (magnetic) such as iron.

Its principle can be considered situation hereinafter described substantially.For convenience of explanation,, suppose that the magnetic pole of annular plate 10 1 sides of magnet 22 is the S utmost point here, the magnetic pole of its opposite side is the N utmost point (opposite polarity situation can be considered equally).Clearly, the magnetic that comes from the S utmost point collects near the tip of cylinder sleeve 26 under the effect as the annular plate 10 of yoke function and cylinder sleeve 26, produces the strongest magnetic force near this tip.Corresponding with it, the magnetic that comes from the N utmost point, under effect as the skirt 66 of yoke function or stiffener 80, accumulate near the periphery of these parts, produce from pointing to the magnetic flux of the S utmost point near this periphery, therefore, part beyond skirt 66 peripheral parts, promptly comprise the skirt 66 peripheral parts part in addition of the part that disposes slide block 56, flow to this a part of magnetic of peripheral part and die down, the magnetic of the slide block 56 that is pulled is also died down.As a result, magnetic is assembled substantially be near the magnetic force cylinder sleeve 26 most advanced and sophisticated of a bit, greater than the magnetic force of the skirt 66 that the magnetic force that only produces magnetic flux is reduced.Therefore, though holding section 65 can not be pulled on the skirt 66, can successfully be adsorbed on the cylinder sleeve 26 with bigger magnetic force.In addition, above narration does not also mean that skirt 66 or stiffener 80 must form with magnetic, still, can consider an effective effect under the situation that they form by magnetic.

Adopting other structures also can successfully be adsorbed on slide block 56 on the cylinder sleeve 26, the magnetic cover that is formed by nonmagnetic substance is set between slide block 56 (particularly its holding section 65) and magnet 22, is a kind of method wherein.For example, intensity or its size according to magnet, holding section 65 with respect to the shape of cylinder sleeve or area, displacement, with the common magnetic action of miscellaneous part, magnetic cover with the thick nonmagnetic substance composition of 0.01mm～10mm is arranged on the holding section 56 of slide block 56 and the position between the magnet 22, thus, just can successfully be adsorbed on slide block 56 on the cylinder sleeve 26.This point that the present inventor is verified by experiment.In addition, replace being provided with this structure of magnetic cover, the plating by enforcement nonmagnetic substance on any one parts between slide block 56 itself or magnet 22 itself or this slide block 56 (particularly its holding section 65) and the magnet 22 also can obtain same effect.Can be adjusted to all thickness according to the time in the immersion plating liquid as for the thickness of electroplating, therefore,, also can obtain and above-mentioned same effect if on slide block 56, carry out the plating of suitable thickness.In addition, there is not the scheme that so nonmagnetic magnetic cover is set in technology before.For example; the spy that the applicant oneself is applied for opens disclosed for clear 50-112170 number such; for the magnet cap of protecting the set nonmagnetic substance of magnet to form; though finally be to place between magnet 22 and the slide block 56; seem just like the such parts of magnetic cover; but, at this in the past in the example, the intention that the magnet cap of this nonmagnetic substance is not used energetically as the instrument that slide block 56 is successfully moved.In other words, opened clear 50-112170 number application originally, and, be easy to fragmentation, and caused magnet to lay, thereby the purpose for protection magnet must be provided with magnet cap owing to for example fragility of ferrite magnet and so on the above-mentioned spy who enumerates.It also is to be provided with for this purpose that the spy opens clear 50-112170 number disclosed magnet cap, does not have the intention that this magnet cap is used as the instrument that slide block 56 is successfully moved of the present invention.The applicant is determined by experiment at the beginning of the application, even above-mentioned nonmagnetic substance still can be used as the magnetic cover that slide block 56 is successfully moved according to its thickness and is used.In addition, this nonmagnetic magnetic cover can make up with magnetic or plating magnetic.Nonmagnetic magnetic cover as other also can be considered spraying or plastic components or other structures.Moreover, substitute the magnetic cover, it also is feasible utilizing the space.In a word, can freely design.

Relevant with above-mentioned principle is that this magnetic fixed fastening did not need to carry out the position of slide block 56 is placed the such operation in latch-release position before first assembly and second combination of components.That is to say, in this magnetic fixed fastening, when first assembly and second combination of components, even clog in the holding section 65 of slide block 56 the permutation hole of second assembly the position, be the occasion of latched position, according to above-mentioned principle, because it is less the force rate that slide block 56 is moved on skirt 66 or stiffener 80 or the magnet 22, and, above-mentioned holding section 65 and engagement pin 34 38 between frictional resistance smaller, thereby, slide block 56 particularly its engagement pin 34 by first assembly 38 with the contacting of holding section 65, nature and be easy to stagger with latched position.In this occasion,, can automatically finish locking in case after holding section 65 staggers with this position, will automatically be adsorbed onto once more on the cylinder sleeve 26.Thereby in this magnetic fixed fastening, before making up, not needing to carry out the position of slide block 56 is placed given position is the such operation in latch-release position.

Fig. 4 is the A-A sectional drawing of Fig. 3.This figure shows the position relation of latched position and the locational slide block 56 of latch-release and its circumferential component clearly.Fig. 4 (a) shows the position relation on the latched position, and Fig. 4 (b) shows the locational position of latch-release relation.

From Fig. 4 (a), as can be seen, be in the position on the outer peripheral face that is adsorbed on cylinder sleeve 26 in the holding section 65 of latched position slide block 56.The result, even want to remove the combination (that is, paper vertical lower in the figure such as engagement pin 34 grades being moved) of first assembly and second assembly, because 38 the contacting of the engagement pin 34 shown in the double dot dash line with the holding section 65 of slide block 56, therefore, can not remove this locking.

In order to unlock, shown in Fig. 4 (b), must make holding section 65 at least from 38 periphery of engagement pin 34 side shifting outwardly.Holding section 65 by make slide block 56 along the direction of arrow in the figure motion and can move.Slide block 56 moves along the direction of arrow, holding section 65 from the beginning 38 periphery push laterally, the result, contact engagement pin 34 contacts with holding section 65.Promptly removed locking.In addition, before and after the releasing of locking, the magnetic of first assembly acts in fact on the holding section 65 of slide block.This is as mentioned above, is caused by the magnetic seal function of the guide 69 of the shape of slide block 56 and skirt 66.

The use example of magnetic fixed fastening of the present invention hereinafter is described with reference to Fig. 5.Magnetic fixed fastening of the present invention can use on various chests, door or other various objects such as handbag or suitcase, ribbon, student's school bag, haversack, cigarette case, briefcase., only be that example describes here with the handbag as representative.Fig. 5 shows first assembly that is fixed on the handbag and second assembly transverse side view with the handbag partial enlarged drawing.

According to present embodiment, first assembly and second assembly be separately fixed at handbag body 4 surface one side and cover 3 inboard.But, in contrast, also can be fixed on first assembly on the lid 3 of handbag, second assembly is fixed on the body 4 of handbag.

These assemblies are fixed on given position by the holding

member

18,54 that is arranged on each assembly.As indicated above, these holding members have two standing parts 18,54 (as shown in Figure 1 and Figure 2), and corresponding with these standing parts, are respectively equipped with first group of hole (not shown) that standing part can be passed on body 4 and lid 3.Each standing

part

18,54 is pressed into these Kong Zhonghou fully, waits laterally (or inboard) to impact each standing part with hammer, makes it crooked, thus, can be separately fixed at body 4 to first assembly and second assembly or covers on 3.As indicated above, second assembly is strengthened the intensity of its above-below direction by the guide 69 of frame 66.Thereby, by this fixed operation, it is destroyed or be out of shape.

In general, this fixing in order to carry out more reliably, between standing part 18 and the body 4 and between standing part 54 and the lid, dispose packing ring 6,5 respectively.These packing rings 6,5 are provided with body 4 or cover corresponding same hole, hole set on 3.When using packing ring, each standing

part

18,54 of holding member respectively according to the hole of body 4 and packing ring 6 or cover 3 and carry out bending after passing these holes with this order in the hole of packing ring 5, also is fine.Moreover, as the method that first assembly and second assembly is fixed on the handbag etc., except utilizing holding

member

14,48, can also adopt additive methods such as riveted and fixed, screw thread be fixing.

When being respectively fixed to first assembly on body 4 and the lid 3, when promptly the lid of handbag being locked, first assembly and second assembly being placed the body 4 of handbag and cover position between 3, it almost be cannot see from the outside to good with second combination of components.The releasing of the locking of this first assembly and second assembly is by in the gap of finger being inserted body 4 and lid 3, pushes that the handle portion 62 of the slide block of second assembly carries out.In order to make this operation be easy to carry out, the handle portion 62 of second assembly is such as shown, be fixed on cover near 3 the edge 7 or co-located proper.Certainly, from the edge 7 stretch better.In addition,, also can consider the shank portion of second assembly is fixed on the handbag, push the method for the handbag part of fixed handle as other release methods.Moreover, though not shown in the figures,, body 4 or cover 3 and be stitched together overlappingly and form by at least two skins or cloth etc.The sweep of each standing part 18,54 just in time can place these two skins or cloth and so on parts between.Therefore, this standing part is invisible from the outside, and in addition, when the edge 7 of handle portion 62 and lid 3 was in co-located, handle portion 62 can counteract, and can not sew up with sewing machine etc.In order to address this problem, when standing part 54 being fixed on when covering 3 given position, if only adopt second assembly is comprised that promptly shank portion 60 and handle portion 62 revolve the structure (not shown) that turn 90 degrees to the left or to the right substantially, just can sew up with sewing machine etc.After this, again second assembly that comprises handle portion 62 is returned to allocation.

According to above fixing means, when first assembly and second combination of components, these assemblies can not reveal the outside in fact, thereby, this magnetic fixed fastening makes on the suitable part of handbag, likes requirement according to the user and implements various ornament (not shown) and become possibility.Therefore, can solve design problem, avoid producing the problem that fully to react user's hobby with attachment fastener.

Though be example with the handbag use example of magnetic fixed fastening of the present invention is illustrated.But magnetic fixed fastening of the present invention is not limited to handbag, is applicable to that also the knob etc. of various chests such as student's school bag or suitcase, ribbon, haversack, cigarette case, briefcase, door needs on the object of locking.Therefore, use the object of magnetic fixed fastening of the present invention, not special the qualification.

In the various embodiments described above,,, can bring into play the same effect of parts that forms with nonmagnetic substance by implementing the plating of nonmagnetic substance on each parts that forms at for example magnetic material in the occasion that parts are formed by nonmagnetic substance.Therefore, in each embodiment, can replace with the magnetic material of the magnetic part of having implemented the nonmagnetic substance plating or nonmagnetic substance covering by the parts that nonmagnetic substance forms.In addition, on nonmagnetic substance, implement the plating of magnetic material or cover the effect that also can bring into play magnetic material with magnetic material.This also goes for when implement electroplating, and the occasion that the part of each parts or all surfaces is made nonmagnetic material or magnetic such as is preventing to get rusty, decorate.Particularly, this method only can be considered to use effectively the part of parts is for example made the occasion of magnetic in the holding section 65 of slide block.In the above-described embodiments, magnet might not be arranged on first assembly, also can be arranged on second assembly, for example, can adopt magnet is arranged on the skirt of second assembly and the method for the position between the stiffener, and, also can omit skirt 66, magnet 22 is placed between slide block 56 and the annular plate 10.Magnet 22 can be plastic magnet or other magnet.Also can be at the enterprising electroplating of magnet.It is also conceivable that additive method.Further, magnetic fixed fastening of the present invention roughly makes cylindrical shape as its integral body, still, is not to make cylindrical shape, also can make for example rectangle tubular, ellipse or other different shapes to its integral body.Obviously, the user can carry out various changes.

Annular plate 10 is not really wanted to resemble and is formed by magnetic aforementioned, can be formed by nonmagnetic material yet.Clearly, the occasion that forms by nonmagnetic material at annular plate 10, under the magnetic action of magnet 22, magnet or cylinder sleeve 26 can not be fixing with respect to annular plate 10, but, by it is welded, adopt adhesives, riveted joint, screw thread is fixed or other the whole bag of tricks are fixed just enough.In addition, the situation of installation holding member 14 also is the same on magnet.

38 as indicated above, and it is suitable being formed by nonmagnetic material, still, is not to be formed by nonmagnetic material, also can be formed by magnetic.

The cylinder sleeve 26 of first assembly is not to pass the spatial accommodation that holds sealing between parts 40 and the skirt 66 when first assembly and second combination of components, and it is neighbouring just enough to arrive slide block 56.In this occasion, under the magnetic action of cylinder sleeve 26, slide block 56 moves towards latched position.

As described in the conventional art, though impair outward appearance when on second assembly, cyclic lug being set,, increase guide 69, this structure is set can prevents transversion malposition between first assembly and second assembly effectively.

For example, rounded edge at the skirt 66 of second assembly shown in Figure 3 is the side of adsorption plane 67, being provided with court's outward extending with the direction of first combination of components (giving prominence to) cyclic lug is edge shape guide, like this, when first assembly and second combination of components, utilize this edge shape protuberance to cover the rounded edge (be meant in the present embodiment for example cover 30 or the rounded edge of the magnet 22 that covers is not set) of first assembly from the outside at 30 o'clock, adopt this method, or, can prevent the transversion malposition between first assembly and second assembly by making up with this method.

In other words, replace guide 69 is set, this edge shape protuberance only is set, also can prevent the transversion malposition between first assembly and second assembly.For example, if promptly the height of the edge shape protuberance of second assembly, the projecting height of the edge shape protuberance on the direction (combinations of directions of first assembly and second assembly) vertical with the front of second assembly (being meant skirt 66 in the present embodiment), set for the height of the engagement pin of first assembly promptly, first assembly of engagement pin on the vertical direction combinations of directions of second assembly (first assembly with) (be meant in the present embodiment as cover 30 or the magnet 22 that covers at 30 o'clock is not set) the outstanding height in front equate substantially, perhaps big slightly, then during first assembly and second combination of components, the edge shape protuberance of second assembly has been stipulated the position of first assembly, therefore, even guide 69 is not set, also can prevent the transversion malposition between first assembly and second assembly.But, the height of this edge shape protuberance can freely be set according to design.

Below, with reference to Fig. 6 to Fig. 8, be described more specifically this edge shape protuberance.Each figure is the center line sectional drawing same with Fig. 3 of magnetic fixed fastening, and the represented parts of the sequence number among the figure and the sequence number shown in Fig. 1 to Fig. 5 are identical or suitable.But, in Fig. 6 to Fig. 8, the guide (Fig. 2, Fig. 36 9) of explanation is not shown above.

The embodiment of Fig. 6 shows and edge shape protuberance 33 is being set on first assembly, the example of magnet 22 is set on the first same assembly.In this embodiment, edge shape protuberance 33 forms on lid 30.When first assembly and second combination of components, be arranged on the edge shape protuberance 33 on the side of adsorption plane 31 of first assembly, in the adsorption plane 67 of second component groups, wrap under its inboard state, be directed to along the side 66a of the adsorption plane 67 of second component groups.After first assembly and second combination of components, the edge shape protuberance 33 of first assembly is from least a portion of the side 66a of the adsorption plane 67 of outer side covers second component groups.According to this structure, when first assembly and second combination of components or after the combination, can prevent the transversion malposition between first assembly and second assembly effectively.In addition, in illustrated embodiment, edge shape protuberance 33 is by carrying out punching press, pull and stretch formation to magnet cap 30, and still, these all not necessarily.For example, when the magnet cap (not shown) was not set, it also was feasible that edge shape protuberance (not shown) is set on the body of magnet 22, also can adopt additive method.Moreover magnet 22 can be plastic magnet, also can be the structure of electroplating at plastic magnet.

Particularly, embodiment as shown in Figure 6 under magnet 22 and situation that edge shape protuberance 33 is arranged on the identical assembly, can obtain magnet 22 and edge shape protuberance 33 and not be arranged on following effect that can not obtain of situation on the same components.For clear and definite these effects, the situation when being assumed to be first assembly and second assembly and not making up.In this state, particularly when the magnetic card of for example credit card or electric car ticket and so on during near the assembly of a side that is provided with magnet, usually, magnetic card can be destroyed under the magnetic action of magnet set on the assembly.But by edge shape protuberance 33 is set on assembly, in the occasion that magnetic card contacts with edge shape protuberance 33, therefore magnetic card can not, can prevent or prevent that magnetic card is destroyed near above-mentioned magnet 22.As everyone knows, in general, magnetic action to be to reduce inversely with 2 times of distance, therefore, even small distance also can obtain fully big effect.

The embodiment of Fig. 7 shows the example that second assembly in contrast with the previous embodiment is provided with edge shape protuberance 75 and magnet 22.But in this embodiment, different with Fig. 6 embodiment is that lid is not set, and edge shape protuberance 75 is set on skirt 66.In this structure, owing to magnet 22 and edge shape protuberance 75 also are arranged on the same assembly, thereby, same with the embodiment of Fig. 6, the destruction that can effectively prevent or prevent magnetic card.In addition, same with the embodiment of Fig. 6, in this embodiment, when first assembly and second combination of components, the set edge shape protuberance 75 in side at the adsorption plane 67 of second assembly, also be under the state of the inboard that the adsorption plane 11 of first assembly is included in this edge shape protuberance 75, side 10a along the adsorption plane 11 of first assembly is directed to, and, after first assembly and second combination of components, the edge shape protuberance 75 of second assembly is from least a portion of the side 10a of the adsorption plane 11 of outer side covers first assembly.Therefore, after first assembly and second combination of components or its combination, also can prevent the transversion malposition between first assembly and second assembly effectively.Particularly in illustrated embodiment, edge shape protuberance 75 is by forming skirt 66 punching presses, pull and stretch, but this is not necessary, can need additive method that this edge shape protuberance is set yet.In Fig. 7, reference symbol 13 represented parts are magnetic covers in addition.

The embodiment of Fig. 7 is by being provided with edge shape protuberance 75, except preventing can also to obtain following effect the transversion malposition.That is to say, when first assembly and second combination of components, two assemblies under the state of dislocation slightly near the (explanation of being done as reference Fig. 5, magnetic fixed fastening of the present invention is in the occasion of body that is used for handbag and lid, the possibility that this state takes place is more more), 38 of the engagement pin 34 of first assembly can not enter in the hole 71 of skirt 66, but contact with the front (adsorption plane 67) of skirt 66, but, in this occasion, according to the present invention, owing to be provided with edge shape protuberance 75, if 38 inboard that enter this edge shape protuberance 75 of the engagement pin 34 of first assembly, afterwards, have only assembly each other (body of handbag with lid each other) stagger a little, be easy to 38 of engagement pin 34 is directed in the hole 71 of skirt 66.Therefore, utilize edge shape protuberance 75 can obtain to make the simple effect of combination of first assembly and second assembly.

The embodiment of Fig. 8 is equivalent to the form of Fig. 6 embodiment and Fig. 7 embodiment combination.Promptly be that edge shape protuberance 75 is set on second assembly, on the other hand, the example of magnet 22 be set on first assembly.In this case, different with Fig. 6 and Fig. 7, though do not have prevention or prevent the advantage that magnetic card is destroyed,, can prevent the transversion malposition between first assembly and second assembly effectively.In addition, the embodiment of Fig. 8 and the embodiment of Fig. 7 are same, can obtain to make the simple advantage of combination of first assembly and second assembly by means of edge shape protuberance 75.

In the embodiment of Fig. 8, particularly the occasion that is formed by magnetic at skirt 66 by edge shape protuberance 75 is set, can further be improved the effect of the absorption affinity of first assembly and second assembly.For to this explanation, suppose the upside configuration N utmost point of the magnet 22 of Fig. 8, the downside configuration S utmost point (situation of opposite configuration can be considered equally).This occasion comes from the magnetic of upside N utmost point side, shown in arrow among the figure, directs into S utmost point side by skirt 66.At this moment, in the present invention, owing to be provided with edge shape protuberance 75, magnetic is guided top, the top 75a of edge shape protuberance 75 from this N utmost point side, from the air that this top, top 75a propagates into, and towards the outside and the below descend, the annular plate 10 by first assembly arrives the S utmost points.Like this, by edge shape protuberance 75 is set, can pass through first assembly and the second assembly both sides effectively from the magnetic flux of the N utmost point, between produces stronger magnetic force.And, can obtain further to improve the effect of the absorption affinity between first assembly and second assembly by edge shape protuberance 75 is set.

In addition, utilize edge shape protuberance 75, can also obtain to make the more firm effect of skirt 66.That is, by edge shape protuberance 75 is set, can improve the intensity of skirt 66, particularly with respect to the intensity of reversing.Because skirt 66 is to be made by relatively thinner plate, therefore, this effect is very important.As indicated above, by edge shape protuberance 75 is set, exist suitable effect, some deterioration to the eye, but after this is remedied, still have suitable effect.

The embodiment of Fig. 9 is opposite edge shape protuberance 33a being set on first assembly, the example of magnet 22 is set on second assembly of the embodiment with Fig. 8.In this occasion, also can obtain and above-mentioned same effect.In addition, on the parts identical or suitable, indicate the sequence number identical with the sequence number of front with above-mentioned cited parts.

Figure 10 shows and adopts other embodiment that prevent the transversion malposition of first assembly and second assembly with the same method of Fig. 6 to Fig. 9.

The embodiment of Figure 10 is at first assembly, particularly the example of the guide 27 of ring-type expansion is set at the downside of its cylinder sleeve 26.The external diameter of expansion guide 27, in other words, the external diameter on (intersection) direction that intersects vertically with the combinations of directions of first assembly and second assembly, set for substantially identical with the external diameter size of the engaging at tip 38, and greater than the external diameter of cylinder sleeve 26 parts.Corresponding with expansion guide 27, near the external diameter the external diameter in the hole of second assembly, particularly its inlet is a bit larger tham the external diameter of engaging 38 or expansion guide 27 in fact.When first assembly and second combination of components or after its combination, the expansion guide 27 of first assembly embeds near the inlet of second component holes, and this just can prevent the transversion malposition of inter-module effectively.In addition, it is identical with an external diameter that engages 38 that the external diameter of cylinder sleeve 26 downsides there is no need in fact, if set the external diameter greater than engaging 38 for, also can obtain same effect.For example, though do not illustrate especially in the drawings,, make cylinder sleeve 26 coniform, its maximum bottom surface external diameter is set for basic identical, perhaps be a bit larger tham the external diameter of this engaging 38, also can obtain in this case and above-mentioned same effect with an external diameter that engages 38.Moreover expansion guide 27 there is no need must do circlewise, also can make rectangle, shaft-like or other shapes.

Other embodiment of slide block 56 of the present invention are described with reference to Figure 11 at last.Slide block 56a shown in Figure 11 compares with the above-mentioned slide block 56 that illustrates referring to figs. 1 through Fig. 5, has only the shape difference of its shank portion 60a, and the shape of other parts is identical.In other words, on the shank portion 60a of the slide block 56a of this embodiment handle portion is not set, the substitute is, be formed for installing the hole 87 that prolongs parts 86.

Prolong parts 86 by on slide block 56a, installing, can prolong the shank portion 60a of slide block 56a in fact.Prolong and in the gap that parts 86 must be installed in for example assembly, particularly body such as second assembly and handbag and lid, to cover the darker position of 3 edge 7.As indicated above, the releasing of the locking of first assembly and second assembly be by in the gap of finger being inserted this body and lid, the shank portion of pushing second assembly carries out.But, when the position of second assembly is too dark, just can not carry out latch-release.

Prolong parts 86 by two metallic plates promptly, interior bar 88 and outside plate 89 form.These metallic plates interfix with diagramatic way afterwards by metal sheet punching press, pull and stretch, bending etc. are formed respectively.Between these plates fixedly is the centre bore 93 that passes inner panel towards the protuberance 94 of outside plate inboard by making, and rivets then and realizes.Certainly, also can adopt solder, soldering, spot welding or additive method.The point of outside plate is the shape that a circular arc is arranged a little that cuts into towards the inboard, and this meets the periphery of skirt 66 in design, also can make other shapes.

Particularly to be conceived to slide block 56a continue the part the tip near.Be formed for accepting the opening 90 of the shank portion 60a of slide block 56a in this part.The size of opening 90 is for wanting can be enough to accept the shank portion 60a of slide block 56a.Slide block 56a is installed in opening 90 places by shank portion 60a being pressed into opening 90.In addition, extract shank portion 60a, just slide block 56a can be disassembled from it from this opening 90.But, in case make install after, just the structure that can not unload sliding block 56a from opening 90 also is feasible.

Near the most advanced and sophisticated central authorities of the inner panel 88 of a part that forms opening 90, be provided with the projection towards the inboard (still, in the drawings, do not express projection, only express recess 91) that forms by being pressed into from the outside.When being installed in prolongation parts 86 on the slide block 56a, this projection 91 goes up the set hole 87 of counterpart with slide block 56a and cooperates.

The most advanced and sophisticated core of the inner panel 88 of projection 91 is set, the elasticity displacement takes place by grooving 92 is set from both sides.Under the effect of this elasticity displacement, the projection 91 of inner panel 88 is installed in given force in the hole 87 of slide block 56a, also can freely unload down from this hole 87 simultaneously.For the more effectively loading and unloading effect of performance prolongation parts 86, inner panel 88 is formed proper especially by phosphor bronze.But be not limited to this, also can adopt other metals such as iron or plastics etc. nonmetal.Though the material of outside plate 89 does not limit especially, considers strength factor, inner panel 88, outside plate 89 preferably all use metal (brass or iron etc.) to form.

For a person skilled in the art, be easy to expect that the various embodiment this specification is put down in writing make up, but, the application also comprises these formations naturally.

According to the present invention, can provide a kind of can reinforcing elements intensity, prevent the magnetic fixed fastening of the dislocation between first assembly and second assembly.In addition, according to the present invention, can also provide a kind of formation that engaging part is successfully moved with magnet.
