Description

Lid with lock

The present invention relates to the box-like latch mechanism of a group of text and be contained in the in-to-in lid.So-called literal assembling lock is meant the lock that just can unblank by the combination that the literal dish of a plurality of display texts, numeral, mark etc. is formed regulation, is called as Keyless combination lock.

The box-like latch mechanism of group of text can also be as not using key just the mechanism of the usefulness of locking, unblank such as strong box can be commonly used except the lock that is used as little iron lock or the locking of bicycle use chain etc.The principle of literal assembling lock is in certain place, by the predetermined mark combination on the literal dish, make the usefulness of unblanking the otch alignment, unblank by overshooting shape member such as pawl is extracted from the notch of alignment.

That the lid that utilizes the box-like latch mechanism of group of text in the past has is that the inventor invents, the Japanese patent gazette spy open clear 7-215356 number disclosed.This lid is that a plurality of clamp rings that the otch of the usefulness of unblanking is set on the part of bottom are configured to concentric circles, by in the otch that is embedded in these usefulness of unblanking, can constitute along the locking member that the radiation direction is supporting movably.A plurality of locking ditches are being set on this locking member, make this locking ditch and each clamp ring unblank combine and this locking member remained on the upper lock position with otch part in addition.As mentioned above, unblank be by rotate each clamp ring, with given mark arrange, after the otch of each usefulness of unblanking is by the alinement shape, make that the locking ditch forms in conjunction with removing, locking member is moved from upper lock position carries out.

In addition, this invention also discloses clamp ring has been divided into dialing circle and hook circle, cuts apart arrangement with regard to the mark that can change the clamp ring when unblanking by this.Like this, the user just can at random set secret signal, when others realizes secret signal or this class problem is arranged, can reset corrigendum, thereby can prevent to lock vanishing of function.

Arbitrarily the structure handlebar dialing circle of change secret signal and hook circle change on the new position method with their setting-ins.But, must decompose catch gear with this method, the change utmost point trouble of secret signal, the function that with great difficulty has becomes and can not use.For sort this problem out, have by dialing circle and hook circle are made and can be regardless of the method that locking mechanism just makes the secret signal change of separating along the structure of rabbeting movingly.But the shortcoming that has secret signal to be changed simply with this method.This is because this structure is just to have changed secret signal by the dialing circle is rotated with respect to the hook circle, and the dialing circle is rotated with respect to the hook circle.Therefore, if under the state that changes secret signal absent-mindedly lock, then the long-term use person can not unblank.

Generally, locking member is not partly extracted from clamp ring the sort of, it is just moved back and forth under the occasion of the catch gear of locking, unblanking in this section, though when locking, clamp ring is in the energy rotary state certainly simultaneously, but then is in the stationary state that can not rotate when unblanking.That is, for from having opened the state of lock, locking member moved and lock, must form the state of arranging according to secret signal to clamp ring, and clamp ring is rotated at all.Therefore, secret signal change is the structure of carrying out when being made into the unlocking condition that the rotation at the hook circle is fixed.Like this, even when unblanking, only do not want to change under the situation of secret signal,, thereby improved the possibility that has changed secret signal unintentionally because lockset position of coupler is identical with the secret signal change of location in order to uncap son.Even secret signal has changed, but, lockset position of coupler do not change because, then still can with similarly unblanked in the past, if in this state, each clamp ring is turned round randomly, then can not unblank again, like this, catch gear itself or utilize the whole device of this catch gear just to become fully and can not use.

The inventor in view of the above problems, study intensively, the result has made lid with lock of the present invention, it is by being embedded on the peristome, utilize this peristome of catch gear hook of the box-like latch mechanism of group of text, it is characterized in that: it is made of clamp ring, locking member and knob; Above-mentioned clamp ring by the top dialing circle of setting up a plurality of marks and can be chimeric with it slidably, on the part of the hook wall of bottom, be provided with and unblank to constitute with the hook circle of otch; Above-mentioned locking member is to be bearing in the below of above-mentioned clamp ring movably along the radiation direction, be provided with the hook wall side face of above-mentioned each hook circle contact, at the above-mentioned a plurality of tight lock parts that pass through with notch portion of unblanking; Above-mentioned knob makes above-mentioned locking member move back and forth along the radiation direction, at least when lockset position of coupler and upper lock position, each tight lock part of above-mentioned locking member is not hinder each hook circle to rotate, and above-mentioned locking member is being provided with a plurality of hook circles maintenance bodies, it is on the assigned position beyond above-mentioned lockset position of coupler and the upper lock position that these hook circles keep bodies, with the hook wall of hook circle unblank to combine with the notch side end.

In the application's specification sheets, so-called " catch gear " is meant and utilizes the box-like latch mechanism of group of text, the structure that can lock and unblank.In the present invention, be to set a plurality of clamp rings, locking member by enclosing the land with one heart and this locking member is constituted along the knob that the radiation direction of clamp ring moves back and forth as catch gear.The material of these members is just passable with general plastics, but the higher material of mechanical strength such as the polycarbonate that is not easy to split during the most handy picking lock, Du Lakang (Duracon), ABS resin.

So-called " clamp ring " is meant the structure that is made of dialing circle and hook circle, setting up kinds of words, numeral, mark etc. (below be called " mark etc. ") above dialing is enclosed and is; The hook circle is can embed with the dialing circle with relatively rotating, be provided with on a part of hook wall of lower end and unblank to use otch.Usually they are formed one,, can be adapted to a plurality of concentric circles rotationally as a clamp ring.By each clamp ring is rotated respectively, make each hook circle unblank be aligned to row with otch, be formed in the notch portion of unblanking to use that forms a line, can lock, unblank along the locking member that moves back and forth of radiation direction.Make and unblank to be aligned to a pair of mechanism with otch and undertaken by the a/s serial arrangement such as mark that dialing circle is set up above, the order of this mark etc. is a secret signal.

Unblank to enclose such 2 members with the hook circle of otch and the dialing of setting up mark etc. by clamp ring being divided into be provided with, the mark etc. that just can at random set the usefulness of unblanking again makes up (secret signal).In the present invention, hook circle and dialing circle are not decomposed, that is, they are not relatively rotated, but this rotation be more solid and reliable than the rotation of the clamp ring that constitutes one with not breaking away from.For this reason, dialing is enclosed and the friction drag of the telescoping part of hook circle except improving, and outside being pushed with spring structure, also can the location division be set at the telescoping part of dialing circle and hook circle.The location division can make rotation not too easy, and each mark etc. that can make dialing circle with respect to the hook circle unblank be positioned on the certain position with otch.Can on the fitting portion at facial set positions such as each mark on the dialing circle recess be set, the hook circle is provided with the protuberance of spring, it is combined and as the location division with recess.In the occasion of protuberance and recess combination, protuberance needn't be arranged to and the recess same number, as long as be provided with just passable at several positions.

Clamp ring is also not necessarily circular, also constitutes the circular-arc of an annulus part, at this moment forms the structure that it is back and forth rotated.In the occasion that clamp ring is rotated, preferably make the mark that is arranged on the dialing circle etc. be positioned to stop at assigned position.For example in clamp ring (dialing circle or hook circle), be provided with the projection of spring at several positions, the hole or the ditch of the same number such as mark in setting and clamp ring on the member that can support this clamp ring rotationally, by above-mentioned projection is embedded in this projection, judge by at this moment sound and thoughts and feelings.

So-called " locking member " be meant a plurality of hook circles that can be adapted to concentric circles rotationally unblank to be aligned to row with otch the time, under a part is embedded in state in this otch, the member that can move back and forth along the radiation direction.By locking member is moved back and forth along the radiation direction, make its hook on peristome or from peristome, lock, unblank with breaking away from.These upper lock position and lockset position of coupler are set at the initial point or the terminal point that move or rotate of common knob, but also can be set in each position, front.Under this occasion, be preferably made above-mentioned location such as combination by recess and protuberance.

So-called peristome is meant the hole that is arranged on certain object, for example is located at the hole on container or the pipe, is arranged on hole on the wall etc.Under peristome occasions such as container, locking member is given prominence in hole set on the internal face of this peristome inboard or middle part, lock thus, locking member is hung on the flange part set around the peristome and lock.

Tight lock part is being set on locking member, and it is to contact with the side face of the hook wall of a plurality of hook circles respectively, and passes through on unblanking with notch portion set on the hook wall.That is, tight lock part makes locking member be held in locking state by it is contacted with the hook side face.But in the present invention, when this tight lock part makes locking member be positioned at lockset position of coupler, must not can the formation obstacle be rotated in clamp ring.Can be following structure as above-mentioned this mechanism, that is, lockset position of coupler is not on the hook wall turned position of each hook circle, even perhaps on turned position, when the hook circle rotates, by the hook wall unblank with the side end of notch it is removed from turned position.Tight lock part is so long as that projection or ditch etc. can combine with the hook wall is just passable.

Below, with reference to the embodiment of the invention shown in the drawings, the present invention will be described in detail.

Fig. 1 is the cross sectional drawing of an embodiment of expression lid 1 with lock of the present invention, is holding latch mechanism 5 in the inside of the cap body 4 that is made of loam cake 2 and lower cover 3.Latch mechanism 5 is arranged into concentrically ringed clamp ring 6, can be arranged on the knob 7 on the central part of this clamp ring 6 pivotally and the locking member 8 that moves along the radiation direction in linkage with knob 7 revolutions constitutes by 3.Clamp ring 6 is made of the dialing circle 61 and the hook circle 62 that can be inlaid in rotationally on the dialing circle 61, makes this hook circle 62 can be bearing on the bottom surface of lower cover 3 rotationally, be on the guide rail 9 that is provided with circularly with one heart.Locking member 8 crosscuts are crossed this guide rail 9 and can be bearing on the bottom surface slidably along the radiation direction like that.On the part of the upper surface of loam cake 2, offering fenestra 11, be attached to each marks 10 above clamp ring 6 and expose so that make.

In the bottom of each hook circle 62 hook wall 12 is being set, the otch 13 of the usefulness of unblanking is being set on the part of this hook wall 12.When the otch 13 of the usefulness of unblanking of each hook circle 62 was alignd along the radiation direction, locking member 8 just can move back and forth along the radiation direction.Therefore, according to each arrangement of additional mark 10 continuously above dialing circle 61, the otch 13 of the usefulness of unblanking becomes alignment.And after otch 13 alignment of the usefulness of unblanking, the mobile of mobile locking member 8 undertaken by knob 7 is turned round.

In this figure, the left side of figure represents that locking state, right side represent unlocking condition, be by making locking member 8 side-prominent, lid 1 hook with lock being located at peristome 21 (referring to Figure 11 (b)), thereby it is locked to the inside of peristome 21 (referring to Figure 11 (b)).3 tight lock parts 81 be arranged on highlightedly locking member 8 above.By making this locking member 8 each clamp ring 6 be rotated at random, make tight lock part 81 just combine and to lock with the hook wall 12 of hook circle 62 from cap body 4.Though much less can freely rotate in each clamp ring 6 of this upper lock position, in the present invention,, make the rotating element of each clamp ring 6 also not have tight lock part 81 or other members even at lockset position of coupler, each clamp ring 6 is made and can be rotated.The change of secret signal is by locking member 8 is moved, thereby makes its tight lock part 81 be positioned at the inside of unblanking with otch 13, under the state fixing hook circle 62, dialing circle 61 is rotated carry out.

The action plate 15 of the driving ditch 14 that has locking member 8 is being set in the bottom of the knob body 71 of knob 7 as shown in Figure 2.By making 71 revolutions of knob body, make action plate 15 revolutions, the projection 82 of the locking member 8 that combines with above-mentioned driving ditch 14 moves back and forth along the radiation direction with regard to being subjected to this to drive ditch 14 guidings.In present embodiment, around action plate 15, recess 16 is set, make on 3 positions such as upper lock position, lockset position of coupler and secret signal change of location and locate.In addition, preferably the knob portion of knob body 71 is made the shape that finger is easily scratched, for example use its base portion is dug the method that more into waits.

As shown in Figure 3, clamp ring 6 is made of dial circle 61 and hook circle 62, and the ditch 17 of setting and mark 10 same number makes its location by the spring projection 18 on the outer wall side that is arranged on hook circle 62 on the part that is embedded in hook circle 62 of dialing circle 61.The occasion that makes whole clamp ring 6 location is that the inwall side at hook circle 62 is provided with in the outstanding spring projection 18 in center, after on the wall of loam cake 2 or the next door ditch 17 being set, makes its cooperation just passable.Under this occasion, preferably being made of dialing circle 61 and hook circle 62, make softly as the tightness of the rotation of clamp ring 6, and that the tightness in relative rotation between dialing circle 61 and the hook circle 62 is made is tighter, makes the combination of mark be not easy to change.This is by shown in Fig. 4 (a) and (b), (c), change hook circle 62 and insert the parts of leading to, and it is just passable to be arranged on the degree of depth of thickness, recess 16 of the spring section of the spring projection 18 of the wall of hook circle 62 and loam cake 2 or the location usefulness between the next door and the spring projection 18 in the recess 16 on 61 li on dialing circle.But, when the rotation tightness of dialing circle 61 and hook circle 62 is done excess enthalpy when tight, can produce the problem of difficult change secret signal.

Fig. 5 is the top view of the locking state of expression lid 1 with lock, is made locking member 8 outstanding from cap body 4 by the rotation of action plate 15.Under this state, each tight lock part 81 of locking member 8 is positioned at the outside of the guide rail 9 of each clamp ring 6 rotations, even combine desire turning knob 7 with the hook wall 12 of hook circle 62, also is in the locking state that can not rotate.

Fig. 6 represents the unlocking condition of lid 1 with lock, by the mark 10 of each clamp ring 6 is arranged according to secret signal, make unblanking of each hook circle 62 with otch 13 alignment, with the combination releasing of tight lock part 81 and hook wall 12, action plate 15 is rotated, thereby locking member 8 is drawn in 4 li of cap body.Under this occasion, each tight lock part 81 is positioned at the inboard of guide rail 9, can not hinder the rotation of each clamp ring 6.

The change of secret signal as illustrated in fig. 7, undertaken by making knob 7 be positioned at the number change of location.This position also is to make the recess 16 on every side that is arranged on action plate 15 combine and locate with spring projection 18.On this position, tight lock part 81 is positioned on guide rail 9 parts, and in otch 13 inside of each usefulness of unblanking.In this state, if clamp ring 6 is rotated, then tight lock part 81 just cooperates with side end in unblanking with otch 13 parts, stops the rotation of hook circle 62, and dialing circle 61 is rotated, and just can be altered to number (mark 10) arbitrarily.

Be the rotation that stops hook circles 62 with tight lock part 81 in the above-described embodiments, but also can be as shown in Figure 8, on locking member 8, be provided with tight lock part 81 not the hook circle of one keep body 83.Fig. 8 (a) is a locking state, and tight lock part 81 is positioned at the outside of each guide rail 9, has the outside that the hook circle keeps body 83 to be arranged in each tight lock part 81 in vain interval that hook wall 12 can pass through.

Shown in Fig. 8 (b), under unlocking condition, each tight lock part 81 is positioned at each guide rail 9 inboard, and each hook wall 12 can keep rotating by ground between the body 83 at tight lock part 81 and hook circle.Secret signal change is shown in Fig. 8 (c), and tight lock part is drawn in, and keeps body 83 to be positioned at that each unblanks to carry out with the inside of otch 13 by making the hook circle.Like this, can be arranged on the number change of location on the position beyond the frequent use part between upper lock position and the lockset position of coupler.

As shown in Figure 9, also can keep the hook circle body 83 to be arranged on the inboard of each tight lock part 81, sky be opened the interval that hook wall 12 can pass through therebetween.Fig. 9 (a) expression locking state, Fig. 9 (b) expression unlocking condition, Fig. 9 (c) expression number change state.Under the present embodiment occasion, the number change of location but makes locking member 8 from the further outstanding position of upper lock position not between upper lock position and lockset position of coupler.Not to stop on the hook circle 62 with tight lock part 81 to rotate, keep by the hook circle under the occasion of body 83 preventions, preferably making the side end and lock section 81 difficulties of the otch 13 of the usefulness of unblanking make band fillet or sharpening on both bound fractions in combination.

It is to rotate that clamp ring 6 is made on lockset position of coupler, and this is under unlocking condition, even clamp ring 6 is rotated, also can not make the secret signal change.In order to reach this purpose, in the various embodiments described above, on lockset position of coupler, make tight lock part 81 or hook circle keep body 83 to be positioned at the turned position of hook circle 62.In the present invention, as long as hook circle 62 does not become and can not rotate on lockset position of coupler, then mechanism in any case can, also can be as illustrated in fig. 10, even keep tight lock part 81 or hook circle body 83 to be positioned on the turned position of hook circle 62, as long as make unblank otch 13 parts of usefulness of hook not, can make its shape of getting rid of from turned position can.If form this shape,, also be utmost point actv. to the rotation of the hook circle 62 that do not hinder even when locking member 8 is not positioned on the lockset position of coupler really.

As making lid 1 with lock be combined in mechanism on the peristome 19, give prominence to the side of the inside of peristome 19 except as the various embodiments described above, making locking member 8, also can be shown in Figure 11 (a), locking member 8 is hung over be arranged on peristome 19 flange part 20 on every side, also can be shown in Figure 11 (b), make the front end of locking member 8 be inserted in 21 li set in hole on the internal face of middle part of peristome 19 and on the hook.

As mentioned above, lid with lock of the present invention be by the dialing circle of affix mark and rotationally setting-in hook circle thereon constitute a plurality of concentrically ringed clamp rings that are adapted to, by using the knob that is arranged on central part, make locking member move back and forth and it is locked along the radiation direction, unblank, can rotate by retainer being made on the upper lock position of this locking member and lockset position of coupler, the hook circle is set on locking member keeps body, on the position beyond upper lock position and the lockset position of coupler, make its side end combine last with the otch of the usefulness of unblanking of the hook wall of hook circle, owing on lockset position of coupler, do not stop clamp ring to be rotated, thereby can eliminate because of changing the danger of secret signal because of carelessness.

And, since the number change of location of change secret signal be arranged on the position beyond upper lock position and the lockset position of coupler, promptly without often by and position that it is stopped, or the position in addition of locking and unblank beyond the common range of use, thereby the user can change secret signal consciously, and can more positively prevent unconscious number change, can prevent locking mechanism effectively or use the devices such as container of this mechanism to become and can not use by the utmost point.
