Description

Lid with lock

The present invention relates to the lid of built-in coded lock, so-called coded lock is meant a kind of lock that has a plurality of lettered dials of literal, numeral, mark etc. just lock can be opened with specific combination expression, is referred to as not have the key combination lock.

Coded lock is except locking the use as padlock and bicycle chain type, owing to just can lock simply, unblank so extensively utilized without key deposit boxes or the like.The principle of coded lock is that the special symbols on the lettered dial is aligned in a certain position so that the breach of the usefulness of unblanking is gathered, thereby the parts of extracting overshooting shapes such as pawl from the notch part of gathering are opened lock.

For example in being provided with the existing deposit boxes of coded lock, be that a certain position that lettered dial multilayer that a certain position with week in it is provided with breach is embedded in its side face is provided with the cylindrical portion of lock pawl guiding with the lid of breach.Promptly, make the breach of lettered dial consistent with breach with lock pawl guiding, thereby the lock pawl at the outer embedding portion of the lid a certain position of side face that is arranged at the deposit boxes body is passed through, after this deposit boxes is built case lid, rotating each lettered dial makes the breach of this lettered dial and this lock pawl guiding separate with breach, so it is relative with the lock pawl not establish the part of breach on the lettered dial, the lock pawl can not come out in pull-off, and is lockable.When unblanking,, make the breach of each lettered dial snap to lock pawl guiding and use indentation, there,, just can open case lid so removed lettered dial and locked the sealed of pawl with the alignment of the mark of predefined each lettered dial.

Yet, utilize in the latch mechanism of existing password latch mechanism, be necessary to be provided with thrusts such as lock pawl on the above-mentioned lock object thing.In other words, for example on being the body of container, object to load onto and the unallied parts of the function of vessel, like this to function with attractive in appearancely all cause impairment.Thereby when covering as covering when being provided with the latch mechanism lid, the form of initial container can be kept, and the shape of vessel naturally and understandably is restricted, and consequently vessel almost can not use separately.

In addition, utilize existing coded lock mechanism, lettered dial exposes, and is easy to from the outside differentiate, and very showy, this also is the reason that latch mechanism partly damages.

So the present inventor studies intensively in view of the above problems with keen determination, its result has obtained this invention, the feature of this lid with lock is that lid embeds peristome, by the latch mechanism that utilizes coded lock mechanism peristome is blocked, and by following component set-up: the somewhere in the bottom of a plurality of concentric circles is provided with the lock ring of unblanking with breach, to embed this lock assembly of unblanking can to install movably along the radiation direction with the state of breach, to make this lock assembly along radiating the handle that direction moves.

At this, so-called " latch mechanism " is meant the structure that utilizes coded lock mechanism to lock and unblank in this specification sheets.In the present invention, latch mechanism is lock ring, the lock assembly that is set by a plurality of concentric circles and this lock assembly is constituted along the handle that the radiation direction of lock ring moves.But the material of these parts generally uses plastics just passable preferably use difficult with high materials of physical strength such as the polycarbonate pried open, ABS resin.

Lock ring is provided with in the somewhere of its lower end and unblanks to use breach.A plurality of lock rings that concentric circles is arranged will unblank separately to gather one with breach and list, so lock assembly just can move along radiating direction, be implemented by moving of this lock assembly and will lock, unblank.For this reason, face is provided with (hereinafter to be referred as " marks etc. ") such as literal, numeral, marks on each lock ring, and each lock ring is combined by predefined mark etc., unblanks thus to gather in row with breach.

Also can and cooperate ring to constitute as lock ring by calibration loop.This be because, be divided into calibration loop and cooperate ring two partly, the mark combination of unblanking just can have been set arbitrarily.In other words, this is because for the mark of facial expression on the calibration loop, cooperates unblanking that the somewhere of ring is provided with can change arbitrarily with the position of breach, is preferably in calibration loop in this case and with cooperating the fitting portion that encircles the location division is set.As the location division, for example the mark of facial each setting on the calibration loop etc. is all established recess at fitting portion, make that to cooperate ring to go up the protuberance and this recess that are provided with chimeric.In addition, the fitting portion of calibration loop is formed polygon with the identical number of quantity such as mark, the fitting portion of interior ring also forms polygon, can embed on the position arbitrarily thus, and this also is fine.Certainly, under the situation of protuberance and recess combination, protuberance there is no need to accomplish with recess and is provided with number, several is set gets final product.

Under the situation of locating by recess and protuberance or polygonal combination, for the combination of the change sign of unblanking etc. is necessary the cooperation ring taken off to change once more from calibration loop to be embedded on the desirable position.For this reason, can turn round chimeric structure, not need to decompose one by one also change sign combination at an easy rate cooperating ring to be paired in calibration loop.Occur easily in this case cooperating the relative calibration loop of ring to be difficult for the more high phenomenon of pivoting friction resistance, the structure by the elastic force location preferably is set.In addition, as calibration loop, also the some of annulus can be done or circular-arc.In this case, circular-arc calibration loop is embedded on the some that cooperates ring, has only the setting of calibration loop partly to do the reciprocating rotating action.

In addition, make under the rotating situation of lock ring, preferably deciding mark of setting on each lock ring etc. in position that institute's allocation stops.For example, on lock ring (character code ring or cooperation ring), establish the jut that several have spring, support this lock ring to circle round to be provided with on the parts that change with lock ring on hole, the groove of set mark equal number, this jut is embedded, at this time can judge with sound, sense of touch.

So-called " lock assembly " is meant unblanking of establishing on a plurality of lock rings (cooperating ring) gathered the parts that move on the radiation direction with the state that embeds this breach when the row with breach.Moving of radiation direction according to lock assembly locked or unblanked, peristome hook together or from opening portion from.So-called peristome is provided in a side of the hole on the jobbie, the hole of container, pipe for example, the hole that wall etc. are located to be provided with etc.Under the situation of the peristome of container etc., set place, hole gets up outstanding edge portion of locking or being provided with of lock assembly and lock section hook to lock with this around peristome on the inboard of this peristome or internal face centre.The mobile of the radiation direction of lock assembly is that the wearing or featuring stage armour hand carries out.For example make handle rotation, or hold handle etc. under the arm and can make the lock assembly interlock.Also can utilize action of the spring in this case on handle or lock assembly, this lock assembly is pulled outwardly or signature inwards on the direction of locking or unblank.

Figure 1 shows that an embodiment of the related lid 1 with lock of the present invention, latch mechanism 5 is being received and kept in the inside of the lid body of being made up of loam cake 2 and lower cover 34.Being constructed as follows of this latch mechanism 5: be provided with the lock ring 6 of two concentric circles, being provided with at the central part of this lock ring 6 can rotating handle 7, the lock assembly 8 that also has the revolution interlock with this handle 7 to move along the radiation direction.Lock ring 6 is installed pivotally to prop up and is held on the track 24 that the bottom surface of lower cover 3 concentric circles is provided with, and lock assembly 8 also can be installed slidably to prop up and be held in this bottom surface along the radiation direction, and this certain one above external loam cake is provided with window 25 to appear the mark 10 above the lock ring 6.

The bottom of lock ring 6 be provided with respectively unblank to unblank on the radiation direction, to gather with breach 9 with this of

breach

9,2 lock rings 6 in, lock assembly 8 can move along radiating direction.For this reason, indicate mark 10 above the lock ring 6 continuously, will unblank to gather at row with breach 9 with the arranged side by side of this mark 10 at each.Unblank to gather with breach 9 one, lock assembly 8 just can move, and turn handle 7 moves it.In this example, locking state is represented in the left side of figure, and unlocking condition is represented on the right side, and the inside side that lock assembly 8 is protruded in peristome 11 is locked thus, makes lid 1 with lock be locked on this peristome 11 places.The groove that unlocking condition one side is represented in the upper end of lock assembly 8 among the figure is to be locking states when the bottom of the locked groove 12 that passes through of the bottom of lock ring 6, lock ring 6 embeds this locked groove 12, and this locked groove 12 and lock ring 6 lower ends are set becomes unlocking condition when unblanking to align with breach 9.Certainly, replacing locked groove is provided with jut and cooperates also with the bottom of lock ring 6 and be fine.

For handle 7, the action plate 15 of the driver slot 14 with lock assembly 8 is being set in the bottom of handle body 13 as shown in Figure 2.Handle body 13 these action plates 15 of revolution are just turned round, and the lock assembly 8 that cooperates with this driver slot 14 moves under the directional tagging of this driver slot 14.In this example, be provided with down above the handle body 13 and play a body 16, erect as showing and be convenient to be used as handle having fallen body 16 image patterns when making it rotating.

Above-mentioned lid with lock, the lock ring 6 of latch mechanism 5 is integrally formed, therefore unblanking that establish target marks 10 and its bottom above the lock ring 6 is constant with the relative position of breach 9, if aim at predefined mark 10 just can unblank, exist combination lock that others has remembered mark 10 with regard to null(NUL) shortcoming.For this reason, as shown in Figure 3 lock ring is divided into calibration loop 17 and cooperates ring 18, their position relation can change.In other words, on calibration loop 17, put on mark 10, on cooperation ring 18, establish and unblank with breach 9, the combination of conversion mark 10 arbitrarily thus, calibration loop 17 is to establish a plurality of walls 26 to cooperate the groove 27 that is provided with this wall 26 of a plurality of embeddings on the ring 18 simultaneously in the inboard of calibration loop 17 with cooperating ring 18 cooperation, with they chimeric combinations that just can change mark 10 on position arbitrarily.

In addition, also can not establish wall 26 etc., as long as calibration loop 17 is reversed under assembled state mutually with cooperating ring 18.Do not decompose calibration loop 17 in other words and cooperate ring 18 and can be set again the combination of mark 10 simply.As shown in Figure 4, lock assembly 8 is inwardly drawn under unlocking condition, cooperate ring 18 unblank move part beyond the locked groove 12 of lock assembly 8 to breach 9, this cooperations ring 18 is in can not rotating state (Fig. 4 right side part), makes lock ring 6 turn round the combination that can make mark 10 and changes.In this case, as by calibration loop 17 with cooperate the revolution of ring 18 lock rings of forming 6 fixing loosening, calibration loop 17 is with to cooperate the relative revolution that encircles 18 to fix the firmer combination that changes mark not too easily such for well.For example Fig. 5 (a) (b) cooperates ring 18 to be inserted logical part by calibration loop 17 shown in (＜), the elastic protrusion portion 19 and the slot part 20 that cooperate conduct location usefulness set between the wall of ring 18 and loam cake 2, then more satisfactory as if the depth of the thickness of the elastic part that can change elastic protrusion portion 19 or slot part 20.

Calibration loop 17 and cooperate ring 18 also can be made the T font with calibration loop 17 as shown in Figure 6, cooperates ring 18 to make the y font, the base portion of calibration loop 17 is embedded into this cooperations encircles in 18 the groove shape portion.Establish elastic protrusion portion 19 at a certain position that cooperates ring 18 sidewalls in this case, the breach 28 that each the mark place under each mark 10 of calibration loop 17 base portions establishes makes it the location with engaging of this elastic protrusion portion 19.Elastic protrusion portion 19 can only establish one, also can establish 2-3.

Lock assembly 8 can be given its trend to the direction of locking by spring 21 as shown in Figure 7.In this case, latch mechanism 5 embeds peristome 11 with lid 1 with lock when unlocking condition, lock assembly 8 resists ground in peristome 11 peripheral parts mutually with spring 21 and introduces, behind this peripheral part, be standing shape again by the effect of spring 21 and only can automatically block, can turn round calibration loop 17 (or lock ring 6) thereafter randomly and lock at peristome 11 places.In addition, also can give the elastic force trend of lock assembly 8 on the contrary, can automatically introduce the state that lock assembly 8, releasing block in this case during 10 one-tenths unlocking conditions of alignment mark to the direction of unblanking.Like this giving under the situation of lock assembly 8 with elastic force trend,, only need establish and push away or draw the mechanism of this lock assembly 8 just passable as the handle 7 that this latch fitting 8 is moved with spring 21.

As the method for lid with lock being blocked at peristome 11, except the various embodiments described above protrude in lock assembly 8 inboard of peristome 11 like that, edge portion 22 places that also can image pattern 8 (a) like that lock assembly 8 clasp joints be provided with around peristome 11, can also be as this figure (b) in the middle of the internal face of peristome 11, establish hole 23, make in the front end inserting hole 23 of lock assembly 8 it is blocked.

The related lid with lock of above the present invention is a plurality of lock rings that set with concentric circles, unblanking of being provided with in its somewhere, lower end is under the embedding state with breach, by handle lock assembly is moved along the radiation direction and implement the structure of locking or unblanking, therefore do not establish other gripping mechanism such as pawl the body of lid is blocked at the peristome that should block.In addition, owing to be that latch mechanism is built in the intrinsic structure of lid, so can use equally as existing inner cap, extremely miniaturization, the setting-in enclosing cover can stash the exposed portions serve of latch mechanism, therefore can not differentiate from the outside and have latch mechanism, and not damage that it is attractive in appearance, have extremely useful effect.
