The invention concerns a folding clasp, with at least three folding arms (1, 2, 3) and a cover (4), these folding arms (1, 2, 3) are mutually articulated and mutually overlap and said cover (4) is articulated with respect to the folding arms (1, 2, 3) for locking the folding clasp by locking said cover (4) on an external arm.
Description
The present invention relates to a snap close, particularly according to a folding snap close of claim.The invention particularly relates to a folding snap close that has three the folding arms that can lock as wrist-watch.
Expandable type watch chain snap close with two articulated arms is well-known.These arms are hinged together mutually with their end each other, the watch chain diameter is increased slide and take off and put on so that can pass wrist to watch chain.Under by the folding state, the arm of these hinges be against each other together and kept this state by a projection of one of them arm, this arm falls into and enters in the groove of another arm.
First kind of defective with snap close of two folding arms is limited expansion.On the one hand, the length of each folding arm should be less than the width of wrist.On the other hand, may take place those user's palms very wide and (or) be some situations that have on ring or other bracelet, this just makes taking off of watch chain and puts on and becomes complicated and cause some worries.
Second kind of defective with snap close of two folding arms is limited volume.Often be that one of folding arm is folded in the groove of another arm and accumulates to avoid latching on the thickness.The thickness of element is a critical standard in timepiece industry, and thickness should be minimum.
The third defective with snap close of two folding arms is stability and limited reliability.Because snap close can take place for wearing and tearing and distortion unexpectedly open tendency is arranged, this causes other worry.
So the objective of the invention is and to bring a solution through these problems,,, have compatible mutually with the known reliable manufacturing technology again structure of a kind of structure very closely for example to the common application of a wrist-watch by creating a kind of folding snap close.

These implementations of a folding snap close have been described three preferred and complementary aspects of the present invention.These preferred implementations are not restrictive at all, and particularly these implementations can be combined and not exceed scope of the present invention.Fig. 1 shows opening and each element of locking mechanism and a plurality of side views, top view and the bottom view in each stage of this folding snap close to the preferred implementation that Fig. 9 represents a folding snap close.Figure 10 represents a preferred implementation of a folding snap close to Figure 15, the variation of the locking of performance lid.
As for those three kinds of preferred implementations, the folding snap close preferably includes three folding arms 1,2,3.Center arm 1 and intermediary's arm 2 are hinged each other by their end.These internal arms 1,2 can one be locked on another arm.In addition, intermediary's arm 2 and external arm 3 are hinged together each other by their end.In case, being arranged in a lid 4 on the center arm 1 removably by locking and being folded on the external arm 3, center arm 1 and intermediary's arm 2 just can make above-mentioned latching in turn down above-mentioned lid 4 locking is arranged on external arm 3 time.There is not any restrictive one in the realization of three folding arms of this usefulness.Understanding professional and technical personnel of the present invention can realize the modification that other is not expressed out and not go out scope of the present invention.For example only realize that with two folding arms or more than 3 folding arms a folding snap close is possible.
Above-mentioned folding snap close is to be embedded into three folding arms going in another 1,2,3 for its feature with one.Center arm 1 is comprised in the breach between intermediary limit two thin slices 2.1,2.2 of intermediary's arm 2 fully, and intermediary's arm 2 is comprised in the breach between external edge two thin slices 3.1 and 3.2 of external arm 3 fully.Obtain a thin and graceful especially structure thus, because the thickness of each folding arm 1,2,3 is not accumulated.Preferably, this center arm 1 and these limit thin slices 2.1,2.2 and 5,7,8 and contact devices 6 of 3.1,3.2 usefulness pins couple together.
Some joint pins 7,8 are used as the hinge of folding arm 1,2,3.Preferably, external arm 3 and intermediary's arm 2 be connected to one another at removably joint pin 7 on the rear portion end points that is positioned at snap close around (just away from nipple pin 5 one side), and intermediary's arm 2 and center arm 1 be connected removably each other joint pin 8 on the anterior end points that is positioned at snap close around (just nipple pin 5 here).
A nipple pin 5 for example is fixed with those external edge thin slices 3.1,3.2 by a screw.Obtain a firm connection thus and make two external edge 3.1,3.2 of external arm 3 become non-removable.That yes is possible in other fixedly enforcement, keeps within the scope of the present invention simultaneously.Above-mentioned nipple pin 5 can be realized a lot of extra functions.In preferred those the two kinds of implementations of a snap close, it is dismountable fixing that above-mentioned nipple pin 5 can make one first watch-guard 100 have according to Fig. 1 to 12.Such watch chain 100 is for example made by elastomeric material, and the watch-guard of a leather particularly, as what represent in Figure 10.Use other host material as the elasticity watch chain, that yes is possible for for example a kind of plastics, is not subjected to any restriction of the present invention.In a preferred implementation of snap close, it is dismountable fixing that above-mentioned nipple pin 5 can make one first end 200 of a watch chain have according to Figure 13 to 15, and it makes that lid 4 is fixing.Such watch chain may be that the softness ring of metal material is formed by some for example.Preferably, the ring of these softnesses by stainless steel and (or) gold makes.Use other host material yes possible, and be not subjected to any restriction of the present invention.
Preferably, this contact device 6 is to embed in the hole of two external edge 3.1,3.2 in non-removable mode.Keep simultaneously within the scope of the invention, realize and other fixing embodiment that yes is possible.Figure 16 represents to be arranged in non-removable mode the contact device 6 preferred another kind of implementations of shape of the transverse brace 61 of light-wall pipe 62 inside.This preferred realization of a contact device 6 can make that the connection of two external edge 3.1,3.2 obtains reinforcing owing to transverse brace 61, and can be to the certain elasticity of this contact device 6, is resilient because manage 62 thin-walled.More clearly, the middle body of above-mentioned transverse brace 61 for example is equipped with one or more thickness surpluses 611, makes that the thin-walled or the lateral parts 6.12 of pipe 62 have a stiff basically tangent to contact with an end points of center arm 1 in this middle body.On the contrary, the part that loses one or more thickness surpluses 611 provides separately space of pipe 62 and transverse brace 61, and can make aforementioned tube 62 flexible stretching, extensions so that for example have an elastomeric slit to contact with the end points 2.6 of intermediary arm 2.For center arm 1 is centered, when it opened or closed, transverse brace 61 was disposed in a small gap in the pilot hole of thin slice of external edge.Above-mentioned arrangement for resilient contacting 6 is metal preferably, and its thin-walled preferably has one 0.15 millimeter thickness.For a littler thickness, maximum stress in bend becomes, and excessive (deformation force is excessive, it is difficult that chucking becomes), for a bigger thickness, the elastic constant of pipe 62 becomes excessive (the thin-walled distortion surpasses the reversible elasticity limit and tightens is not have very much power).Therefore concerning a pipe 62 made from metal material, stainless elastic tube for example, one 0.15 millimeter thickness has been represented a desirable selection, making simultaneously has one to limit to such an extent that power that close very accurately or chucking (is felt just in time, neither excessive firmly not too small again exerting oneself), can guarantee that contact device 6 has an easy processing and fabricating simultaneously.In addition, the pipe 62 of a kind of different materials of selecting to compare with the steel of folding arm 1,2 or transverse brace 61 (for example Nivaflex, Phynox etc.) is proved to be wisdom, and this has just guaranteed to have a good coefficient of friction.Using a pair of like this molecular structure is desirable with all different material of difference in hardness, can guarantee to tighten big variation, because stainless elasticity is not invariable, and its chemical composition is not the chemical composition of an elastic tube.Use other host material yes possible, be not subjected to any restriction of the present invention.
The quality of a snap close not only by its pure technical characteristic decision, is also determined by the impression that produces on one's body the user.With those known snap close differences, those do not use and are equipped with a transverse brace and a thin-walled tube is regulated those power with such arrangement for resilient contacting of the chain of a secondary different materials in indivedual modes, and the chucking characteristic of particularly regulating the folding snap close is possible.In that for example more or less thick or more or less flexible pipe replaces this pipe with another, just might regulate the reaction of chucking in individual other mode, just regulate the hardness of ratchet and the relation between the sensitivity.An important criterion is represented in a kind of adjusting so in fact for the user, can compare with fineness with the grace of snap close.Make a profound impression to the people with the sensitive performance that can allow snap close open and close likablely.This standard often plays a conclusive effect, for example when buying a wrist-watch and have such folding snap close.
When people use folding to latch in elastic webbing watch chain (particularly leather band watch chain), those implementations according to Fig. 1 to 12, above-mentioned snap close preferably includes a lid 4 and has a top part and partly open in its central authorities, and Here it is because the result that the very flat snap close with minimum volume causes.Fig. 2 and Figure 10 express the bar 4.11 that one second watch-guard 110 is fixedly placed in the sidewall 14 of lid 4 and the lid 4 of ining succession well.Above-mentioned second watch-guard 110 ideally matches with the curvature of the contact surface of the top inwall of lid 4, and it also ideally matches with the curvature of the corresponding contact surface of bar 4.11.Those shapes that participate in the contact surface of elements just are comprised in 4.12 li of the central openings on the top of lid 4 as the curvature of one second watch-guard that is caused by bar 4.11.The curvature of one second watch-guard 110 that is caused by the curvature of the inwall on the top of lid 4 is stable and reinforce the fixing of this second watch-guard 110.Preferably, lid 4 is connected on the center arm 1 that passes above-mentioned bar 4.11 removably.From Fig. 1 to 9 and from the realization of the lid 4 of Figure 10 to 12 in fact be distinguishing according to the preferred implementation of Figure 10 to 12, central opening 4.12 is laid more by the central authorities of lid 4, so give second watch-guard 110 bigger space, and make lid 4 have the bar 4.11 of being put on watch chain 110 around have one more obviously to rotate.The appearance of this snap close is graceful especially, because it is compared with other snap close is very flat, people open to its central authorities from the top of lid and win a dot thickness, again because the above-mentioned heavy and firm appearance of snap close neither one with lid 4 of opening towards its central authorities.
The folding snap close is a feature with two different lockings, that is to say with first locking that carries out between two in folding arm 1,2,3 with second locking that is undertaken by at least one and lid 4 in the folding arm 1,2,3 to be its feature:
-represent first kind of locking being undertaken by one first locking device to the preferred first kind of implementation of Fig. 9 according to Fig. 1, this locking device is realized as for example one or the shape of a lot of spring ball 9 of center arm 1, for example is realized as one or the shape of several dead slots 2.9 of intermediary's arm 2 with at least one first counterpart.
-represent first locking that undertaken by one first locking device to Figure 15 preferred second kind and the third implementation according to Figure 10, this locking device is implemented or the shape of a concave ends 2.6 of intermediary's arm 2 for example, with at least one first counterpart, it is realized as for example shape of one or more lateral parts 6.12 of a contact device 6 of external arm 3.
-represent one second locking being undertaken by second kind of locking device according to Fig. 1 to 12 preferred first kind and second kind of implementation, this locking device is realized as for example flange shape on the sidewall of lid 4, with at least one second counterpart, it is realized as for example shape of one or more dead slots 3.10 of external arm 3.
-represent second kind of locking according to preferred the third implementation of Figure 13 to 15, carry out with the shape of the flat side wall 14 of for example lid 4 with at least one second counterpart, this second counterpart for example realizes with the shape of one or more end points 6.14 of the contact device 6 of external arm 3.
Represent one first locking being undertaken by first kind of locking device according to the preferred first kind of implementation of Fig. 1 to 9, this locking device for example is made up of two spring balls 9 in the side opening that is arranged in center arm 1.Each spring ball 9 all is made up of a ball that is connected with spring.These lax springs be fixed on above-mentioned side opening inside in case those balls just over the exterior side wall of center arm 1.Center arm 1 turnover on intermediary's arm 2 time, center arm 1 is completely contained in the groove between two limit thin slices 2.1,2.2 of intermediary's arm 2.Those spring balls 9 are in by near those first counterpart that for example realize with dead slot 2.9 shapes of intermediary's arm 2.Those spring balls 9 flexibly are compressed, and remain in this primary importance of being closed by the otch 2.5 that is arranged in 2.9 li of these dead slots.Understand professional and technical personnel of the present invention and can realize other modification of not being expressed out, and do not go out scope of the present invention.
Represent one first locking being undertaken by one first locking device according to Figure 10 to 15 preferred second and the third implementation, this first locking device is implemented with the shape of a concave surface end points 2.6 of for example intermediary's arm 2, with one first counterpart, this counterpart is implemented with the shape of a lateral parts 6.12 of a contact device 6 of for example external arm 3.When being folded to center arm 1 and intermediary's arm 2 on the contact device 6, above-mentioned end points 2.6 use chucking and by an otch flexibly towards above-mentioned lateral parts 6.12 compressions.Understanding professional and technical personnel of the present invention can realize other modification that is not expressed out and not go out scope of the present invention.For example may realize a groove contact snap close,, realize that with center arm groove contacts snap close too and in a similar fashion not only with intermediary's arm.Contact device 6 may be a firm pin and (or) may form by a transverse brace 61 and a light-wall pipe 62 according to Figure 16.
Represent one second locking according to Fig. 1 to Figure 12 preferred first kind and second kind of implementation, it is made up of two flanges 10 on the sidewall that for example is arranged in lid 4.When being folded to lid 4 on the external arm 3, these flanges 10 for example be in those second counterpart that the shape with dead slot 3.10 realizes near.Those sidewalls of lid 4 flexibly expand, and above-mentioned flange 10 is maintained in the second place that this otch 3.5 that is arranged in 3.10 li of these dead slots closes.Understand professional and technical personnel of the present invention and can realize other modification of not being expressed out, and do not go out scope of the present invention, for example lid 4 is with a fluting of an internal arms 1,2, perhaps for example in the inside of lid 4, the use of flat side wall 14, rather than at the inside of lid 4 use flange 10.
Represent one second locking being undertaken by the shape of the sidewall 14 of for example inside of lid 4 according to preferred the third implementation of Figure 13 to 15, carry out with some second counterpart that for example realize with the shape of the end points 6.14 of the contact device 6 of external arm 3.This contact device 6 is fixed on the inside of the pilot hole of external arm 3, so that its end points 6.14 is just over those exterior side wall of external arm 3.Contact device 6 can be a firm pin and (or), it can be made up of a transverse brace 61 and light-wall pipe 62 according to Figure 16.When lid 4 being folded on the folding arm 1,2,3, these flat sidewalls 14 be positioned at end points 6.14 near.Those sidewalls 14 of lid 4 flexibly expand, and are maintained in this pent second place.Understanding professional and technical personnel of the present invention can realize other modification that is not expressed out and not go out scope of the present invention.For example, perhaps for example use flange 10 and do not use flat side wall 14 in the inside of lid 4 in the inside of lid 4 with the fluting of the lid 4 of an internal arms 1,2.
The folding snap close shows its feature with the shedding mechanism of the uniqueness of a novelty.Snap close for example is designed in order to use with an elasticity watch chain (preferably leather) and (or) for the chain link watch chain of a softness (preferably stainless and (or) gold) uses.Two kinds of definite uses of this of snap close are celebrated with the preferred implementation of opening mechanism.Self-evident these implementations are interchangeable, that is to say for the preferred implementation of using a snap close with an elasticity watch chain also to be used for a soft chain link watch chain.
Opening of the snap close of closing for the elastic webbing watch chain according to two kinds of implementations of Fig. 1 to 12 is that two lockings by untiing two locking devices 9,2.6,10,14 and corresponding counterpart 2.9,6.12,3.10,6.14 are in succession finished.
The release of-the second locking device (being arranged in two flanges 10 of inside of sidewall of lid 4 or the flat side wall 14 of lid 4) is for example by drawing the end of second watch-guard 110 to finish along the tensile force F direction of arrow, and this can make mentions above-mentioned lid 4 (please see Figure 10).When snap close being imposed such tensile force F, people can pull out the sidewall of lid 4, these sidewalls are closed by the otch of flange 10, and those flat side wall 14 of lid 4 are respectively 3.10 li of some dead slots or respectively externally on some end points 6.14 of arm 3.
-unlocked like this lid 4 can rotate around bar 4.11.Because second watch-guard 110 ideally matches with the curvature of the contact surface of the inwall on the top of lid 4, it also ideally matches with the curvature of the corresponding contact surface of bar 4.11, it similarly with by the part of the outer surface of the folding arm 2,3 of joint pin limited range matches, and this joint pin is positioned at the rear portion end points of snap close and lid 4 is located substantially on the central authorities of snap close.Because the elasticity of second watch-guard, watch-guard is compressed a little, and the result produces certain certain tightening.People draw the end points of second watch-guard 110 along the direction of arrow of tensile force F, lid 4 just rotates around bar 4.11 more, intermediary's arm 2 and (or) the reaction force R that transmits of 23 li second supported watch-guards 110 in zone of the outer surface of the external arm 3 of snap close will become big more.This tightening not necessarily, but it makes watch-guard 110 that such support be arranged on folding arm 2,3.Understand the modification that professional and technical personnel of the present invention can realize that other is not expressed out, for example use the link formula watch chain of a softness or use an elasticity watch chain that partly is reinforced, and do not go out scope of the present invention.
-watchband the element 110 that linked together by watch-guard 110 like this, lid 4 and center arm 1 form one can rest on intermediary's arm 2 and (or) lever on the outer surface of external arm 3.The end points that can untie center arm 1 for example when this lever is stated reaction force R in the use with one for example by external arm 3 one on first counterpart (the please see Figure 11) tangent realized of a lateral parts 6.12 of contact device 6 contact.The end points of center arm 1 this freed and touched device 6 rotation center arms 1 by solderless wrapped connection basically and finish.Contact device 6 can be a firm pin and (or) may form by a transverse brace 61 and a light-wall pipe 62 according to Figure 16.
In case center arm 1 is untied, pull on watch-guard 110 with a tensile force F simultaneously, so that further uncover lid 4, the open angle α that is formed by the longitudinal axis of center arm 1 and intermediary's arm 2 increases, one first locking device of otch (please see Figure 12) release that concave ends that this open angle can also be by untiing intermediary's arm 2 and first counterpart that is for example realized by lateral parts 6.12 shapes of a contact device 6 of external arm 3 form.When people use one during by the contact device 6 formed according to transverse brace 61 of Figure 16 and light-wall pipe 62, this release of concave surface end points 2.6 mainly be by flexibly make above-mentioned intermediary arm 2 and (or) 62 decompressions of thin-walled elastic tube carry out.
The third implementation according to Figure 13 to 15 is opened for a snap close of the soft link watch chain of closing, and finishes with corresponding counterpart two lockings together by progressively untiing two locking devices.
The release of-the second locking device (internal side wall of lid 4) for example is to finish (please see Figure 14) by directly uncovering lid 4 along the direction of arrow of lid tensile force F '.By to this lid tensile force of snap action F ', people can emit those sidewalls 14 of the lid 4 of being closed by the otch of the end points 6.14 of the contact device 6 of external arm 3.Understanding professional and technical personnel of the present invention can realize other modification and not go out scope of the present invention.In order realizing and an otch of the end points of a contact device of external arm, for example can to use the flat side wall of lid, and on the sidewall of lid, not carry out flange in advance.Similarly externally be beforehand with better contact flange on the lateral parts of arm, this can for example replace those end points of a contact device.Contact device 6 can be a firm pin that has an end points 6.14 and (or) it can be made up of a transverse brace 61 and a light-wall pipe 62 that has end points 6.14 according to Figure 16.
-when above-mentioned snap close is under the closed condition, lid 4 partly is placed on the end ring 40.The lid of untiing 4 can rotate around nipple pin 5, and becomes enterable with second watch-guard 210 of an end ring 40.The definite function of above-mentioned lid 4 is any possible the opening that stop end ring 40, can act on a tensile force F on end ring.Preferably, lid 4 can partly be placed on the projection of end ring 40.Particularly, the contact jaw of lid 4 and end ring 40 be each other connect mutually so that the appearance of this snap close is very smooth and graceful.Compare with other snap close, the top of the contact jaw that makes end ring become flat in people when winning thickness and being placed on the end ring 40 with convenient lid 4 people can not distinguish boundary between lid 4 and the end ring 40.The nipple pin 50 of this end ring 40 in a hole that is arranged in center arm 1 is dismountable.When the direction of the arrow of tensile force F is drawn second watch-guard 210, end ring 40 rotates around nipple pin 50, and a reaction force R is transmitted for 23 li in a zone of outer surface that is supported on the external arm 3 of snap close.Understanding professional and technical personnel of the present invention can realize other modification that is not expressed out and not exceed scope of the present invention.
-watch chain list cell spare 210, end ring 40 and center arm 1 form a lever on the outer surface that can be supported on external arm 3.This lever is stated in the use center arm 1 is rotated around first counterpart.This first counterpart is (please see Figure 15) with the shape realization of for example contact device of external arm 3.
In case-center arm 1 frees from a tangent contact or from a groove contact, when pulling on watch-guard 210 with a tensile force F so that lifting end ring 40 more, the opening angle that is formed by the longitudinal axis of center arm 1 and intermediary's arm 2 increases, the otch that first counterpart that the concave surface end points 2.6 that this can be by untiing intermediary's arm 2 is realized with the shape with a lateral parts 6.12 of a contact device 6 of for example external arm 3 forms (be not expressed out but similar with Figure 12) one first locking device of release.This release of concave surface end face 2.6 be basically flexibly make above-mentioned intermediary arm 2 and (or) make 62 decompressions of thin-walled elastic tube and finish, when people use contact device 6 being made up of transverse brace 61 and light-wall pipe 62 according to Figure 16.
By the main advantage that watch-guard 110 is pressed on this lever opening mechanism on the folding arm 2,3 is exactly just can open snap close by enough relatively little tensile forces.When comparing with opening of a traditional snap close (tensile force is by directly drawing those folding arms of wanting release to obtain), this multiplication linkage reduces much tensile force.In preferably realizing according to Figure 10, by the determined lever ratio of distance of 6 lateral parts 6.12 from supporting zone 23 to contact device with respect to directly drawing the needed tensile force of those folding arms of wanting release to make the tensile force F of a factor 6 have one to reduce, self-evident understanding professional and technical personnel of the present invention can realize other modification that is not expressed out of a lever, for example use a greater or lesser lever ratio, and do not exceed scope of the present invention.
The folding snap close is with two its feature of performance of opening, and this increases the diameter of watch chain and watch chain is slided and takes off and put on wrist-watch so that can pass wrist at an easy rate.Consider and preferably use three folding arms rather than two habitual folding arms, the watch chain diameter of the folding snap close of opening is big more, and it is easy more to make the user take off and put on watch chain.For the user that roomy palm is arranged mediate a settlement (or) have on the people of ring or other chain that this seems highly significant.
The folding snap close is only can be easy to substitute or regulate the element of minimum number with people realize.People can change the power of first locking at an easy rate and it is fit to by use other spring ball, with other of correspondence for example have different elastic characteristic concave surface end points replace those spring balls with (or) those concave surface end points.People can be at an easy rate by have with another flange and (or) lid of a difform internal side wall replaces that lid and changes and the power of second locking is fit to.Understand professional and technical personnel of the present invention and can realize similar multiple enforcement.
The visible element of those of folding snap close is metal preferably, they for example use stainless steel and (or) gold makes, that yes is possible in the use of other host material, is not subjected to any restriction of the present invention.The visible element of all of folding snap close that is to say that those folding arms, lid and those pins preferably all are processed to metal integral, and inserts by reality and to connect.This can make an appearance that is easy to processing and snap close have one to change fast.In addition, the element that these have a special symmetry and stability guarantees an operation reliably and an easy maintenance.An important advantage is to avoid fully welding.Consider for one of snap close easily and a pinpoint accuracy of the start request that repeats is considered the technical difficulty (hardness lowers and asymmetric distortion when welding) that runs into so avoided welding to seem it is favourable when the materials processing of selecting is handled.For other host material, understand fixing means that professional and technical personnel of the present invention certainly realizes other for example to the hot melt of some hot melt synthetic materials etc.
