In order simplifying operating portion have been carried out the step after the unlock operation, to be preferably, constituted operating portion as follows: make elastic force along locking directive effect on this operating portion, owing to the operating physical force disappearance of unlock operation, thereby this operating portion is to the direction action of locking.

In order to make unlock operation and the co-operating swimmingly of the opening operation after it, be preferably the operating portion double as opens and closes usefulness to open and close member handle.

Can enumerate such example as concrete embodiment: the dial-type coded lock has bar and action body; Wherein, Said bar is loaded to a direction elasticity; It overcomes resilient movement during to sign indicating number to assigned position and be maintained at said assigned position in dial-type coded lock main body, and at non-this confining force of removing during to sign indicating number; Said action body is non-ly reseted holding state to the sign indicating number state, through placing to the other direction action and with dial-type coded lock main body through being reset to the action of direction and with dial-type coded lock main body; Carry out related with between said bar and the said operating portion by means of the 1st related portion; Thereby non-ly forbidding the unlock operation of said operating portion during to sign indicating number, to sign indicating number the time, allowing this unlock operation; And; Related with carrying out by means of the 2nd related portion between said action body and the said operating portion, thus follow unlock operation dial-type coded lock main body to be reset to non-to the sign indicating number state to this operating portion behind the sign indicating number.

Be applied in the structure on the furniture for accommodation such as locker as being used to, be preferably, the said holding section and the portion of being stuck become that any side is that sickle shaped stretches out and the opposing party with the relation of its admittance.

In this case;, open and close member with the interference that is stuck portion it is engaged when being carried out closure in order to avoid the holding section rightly; Preferably constitute the holding section as follows: the unlock operation of operating portion is disengaged after the dial-type coded lock is to sign indicating number, and thus, the holding section resilient movement is to upper lock position; Said holding section overcomes elastic force with the portion butt of being stuck before the make position and carries out the avoiding interference action temporarily through being about to arrive at open and close member, engages with the portion of being stuck then.

Carry out swimmingly for the action that makes this moment, be preferably, the holding section is constituted to carry out avoiding interference action and traction operating portion not.

Such formation especially can very be applied to such device suitably: holding section or be stuck any side of portion is the member along the switching direction of the open and close member that is in the close position is extended, the top has the claw of bending.

And; If the locking and unlocking device of this embodiment is applied between open and close member and the casing; Do not require that then precision can carry out the locking and unlocking device is assembled simply, reliably; Make its action steady in a long-term, make the ease of use that improves the accommodation device of having used this locking and unlocking device effectively become possibility.

In addition, in order to reach this purpose, the present invention has adopted other following means.

That is, locking and unlocking device of the present invention has: casing; Be used to open and close the open and close member of the opening of this casing; Be located at any side's of said casing or said open and close member dial-type coded lock, operating portion and holding section; The portion that is stuck with any the opposing party who is located at said casing or said open and close member; Through this holding section and this portion of being stuck being fastened and said open and close member being remained on make position, it is characterized in that: said operating portion is accepted unlock operation and said holding section is switched to lockset position of coupler with respect to the said position that is stuck portion from upper lock position; Said dial-type coded lock passes through related portion at least by related with said operating portion; Its interrelational form does; At least when open and close member is closed; In the non-unlock operation of forbidding said operating portion during to sign indicating number, to sign indicating number the time, allow this unlock operation and with thereafter unlock operation interlock and be reset to non-to the sign indicating number state; Said holding section is constituted as; Open putting aside when the back is disengaged the unlock operation of said operating portion under the state of the action force of upper lock position at open and close member and be maintained at lockset position of coupler; The stage that has moved to make position at said open and close member once more is automatically moved to upper lock position owing to said action force is disengaged, and engages with the said portion of being stuck.

In the device that so constitutes, when open and close member is in the close position, during to sign indicating number, forbidden by the dial-type coded lock, the situation that the holding section moves to lockset position of coupler can not take place by the unlock operation of operating portion non-for the dial-type coded lock.Next, in case the dial-type coded lock by to sign indicating number, promptly is disengaged to the illegal state of operating portion, unlock operation obtains allowing.In case operating portion has been carried out unlock operation, the holding section promptly moves to lockset position of coupler from upper lock position, becomes the state that can open and close member be opened.In addition, follow unlock operation, the dial-type coded lock is reset to non-to the sign indicating number state.After opening, even be disengaged to the unlock operation of operating portion, the holding section is also being put aside towards the action force of upper lock position and is being maintained on the lockset position of coupler.And, make open and close member move to the stage of make position once more, the holding section is owing to the action force of being put aside is disengaged and is fastened in the portion of being stuck automatically.At this moment because that the dial-type coded lock is in is non-to the sign indicating number state, the unlock operation of quiescing portion, so as long as the dial-type coded lock not by to sign indicating number, just can not operate operating portion once more.

Like this, after the dial-type coded lock was to sign indicating number, operating portion became and does not receive to restrict; Next, as long as operating portion is carried out unlock operation, the holding section just can switch to lockset position of coupler from upper lock position; And the dial-type coded lock is reset to non-to the sign indicating number state; After opening open and close member, as long as making open and close member move to make position once more just can be placed on locking state, so this locking and unlocking device can supply to use with few step.

And; Owing to the dial-type coded lock is reset to non-to the sign indicating number state with the operations linkage of operating portion; So with, for example, compare to utilize open and close member to reset the situation that the mode of dial-type coded lock constitutes for the relative action of casing; Need not the dial-type coded lock to be embedded between casing and the open and close member, make and realize effectively that through simple easy assembling the locking and unlocking device of action becomes possibility reliably with good precision.

In addition, elasticity is provided with spring 24a between movable link 23 and near the fixed component it 24, and this spring 24a gives movable link 23 to fall the elasticity of direction.This spring 24a is bringing into play holding section 21 effect that (direction of locking) pressed towards the below.In addition; Owing to act on the spring 30a on the action body 4; Shown in Fig. 6 (b), effect has the elastic force of the rightabout towards arrow---direction of locking---on operating portion 22, and the operating physical force that operating portion 22 is understood because of the direction of unblanking that is input to operating portion 22 disappears to the direction action of locking.In case operating portion 22 moves to the direction of locking, movable link 23 is just fallen in the opposite direction of the arrow shown in the effect lower edge of spring 24a Fig. 6 (a), and holding section 21 returns to upper lock position.During the external force that makes progress at closing time that will explain in 21 side effects back, while movable link 23 traction operating portion 22 and compress the spring 24a action that moves upward not from the holding section.

The moving body 52 that constitutes the 1st related C of portion is becoming the state that slips under the baffle element 51 under the state shown in the Fig. 5 after the unlock operation, this explains in front.And; When unlock operation owing to operating portion 22; Digit wheel is reset to non-during to the sign indicating number state; Because bar 31 rotates downwards, baffle element 51 is loaded to falling direction, and stretch out action in the moving body 52 of body 4 under spring 30a effect that move during with the operation of having removed operating portion 22 desired to return the motion of origin-location and interfered.So; Be provided with the spigot surface 52d of curve form on the position that in moving body 52, contacts, make moving body 52 can be on one side baffle element 51 be mentioned on one side from it down through returning to and move the corresponding position of extended position of body 4 along this spigot surface 52d with baffle element 51.Bar 31 and baffle element 51 are offset to the position of falling of Fig. 3 therefrom.After this, if digit wheel not by once more to sign indicating number, the unlock operation of this operating portion 22 just is under an embargo, therefore the 1st so related C of portion can be described as ratchet structure.

Next the action of this embodiment is described.

At first, door 2 is in the make position shown in Fig. 7 (a), and non-to the sign indicating number state if dial-type coded lock 3 is in, then the confining force of bar 31 is disengaged, and bar 31 is in the turned position, below by spring 32 loadings.This moment, the operation of operating portion 22 was forbidden that by the 1st related C of portion holding section 21 is in the upper lock position that is fastened in the portion of being stuck 11.Next, in case make 3 pairs of sign indicating numbers of dial-type coded lock, bar 31 promptly moves to the turned position, top and is maintained at this position because of the function of dial-type coded lock 3 shown in arrow among Fig. 7 (b), and the illegal state that the 1st related C of portion forms is disengaged., shown in Fig. 8 (a), operate through the grip 22a to operating portion 22, holding section 21 rises to removes and the lockset position of coupler that engages that is stuck portion 11 for this reason, and will move body 4 by the 2nd related D of portion and push and digit wheel is made zero.If under this state, open door 2, then shown in Fig. 8 (b), the accommodation space of casing 1 is opened.When such making zero, the confining force of bar 31 is disengaged, bar 31 trend towards under the effect of spring 32 towards below the turned position rotate.In case remove the operation to operating portion 22, operating portion 22 promptly rotates to the direction of locking because of elasticity, follows in this, and holding section 21 is lowered to the upper lock position shown in Fig. 9.Same when state and Fig. 7 (a) of the dial-type coded lock 3 of this moment, the 1st related C of portion becomes the attendant exclusion state once more, and the body 4 that moves stretches out and is transferred in order to carry out the holding state of reseting of retraction next time.

As shown in Figure 9 with door 2 when closed; Because holding section 21 is positioned at upper lock position; If so at that towards make position, then can interfere with the opening edge that is stuck portion 11, even but because while holding section 21 is in not also traction operating portion 22 and compress spring 24a move upward (with reference to Fig. 6 (a)) by means of movable link 23 not of operable state at operating portion 22; So in order to avoid and the interference that is stuck portion 11; Holding section 21 was once overcoming the elasticity of spring 32, under the effect of spring 32, moved downwards once more after shown in arrow among this figure, crossing the opening edge of the portion of being stuck 11, returned to the upper lock position of Fig. 7 (a).At this moment, the claw 21a of holding section 21 is fastened on the back side of the open circumferential of the portion of being stuck 11, and dial-type coded lock 3 is kept the state of making zero.

As stated; The locking and unlocking device of this embodiment has door 2 as the open and close member of the opening 11 that is used to open and close casing 1 and this casing 1, is arranged on dial-type coded lock 3, operating portion 22 and the holding section 21 on the said door 2 and is arranged on the portion that is stuck 11 on the said casing 1, fastens and remains on make position with said 2 through making this holding section 21 and this be stuck portion 11.

And, said operating portion 22 is constituted: can after accepting unlock operation, said holding section 21 be switched to lockset position of coupler with respect to the said position that is stuck portion 11 from upper lock position; At least carry out related with operating portion 22 said dial-type coded lock 3 through the related C of portion, D; Its interrelational form is: in the non-unlock operation of forbidding said operating portion 22 during to sign indicating number, to sign indicating number the time, allow this unlock operation and with thereafter unlock operation interlock and be reset to non-to the sign indicating number state; Said holding section 21 is constituted: be automatically moved to upper lock position and be fastened on said being stuck in the portion 11 in the time before the said door 2 that the unlock operation to said operating portion 22 is disengaged moves to make position once more.

Like this, behind 3 pairs of sign indicating numbers of dial-type coded lock, operating portion 22 becomes and does not receive to restrict; Next as long as operating portion 22 is carried out unlock operation, holding section 21 just can switch to lockset position of coupler from upper lock position, and dial-type coded lock 3 is reset to non-to the sign indicating number state; And; Just can make it become locking state as long as make door 2 move to make position, therefore, this locking and unlocking device A can supply to use through few step.

And; Owing to dial-type coded lock 3 is reset to non-to the sign indicating number state with the operations linkage of operating portion 22; So with, for example, reset the situation that the mode of dial-type coded lock 3 constitutes with the relative action that utilizes 2 pairs of casings 1 of door and compare; Need not dial-type coded lock 3 is assemblied between casing 1 and the door 2 with good precision, make and realize effectively that through simple easy assembling the locking and unlocking device A of action becomes possibility reliably.

In addition; Because the related C of portion among the said related C of portion, D adopts ratchet structure, that is: at dial-type coded lock 3 since the unlock operation of operating portion 22 be reset to non-to the sign indicating number state after, under the situation that this unlock operation is disengaged; Allow the recovery action of operating portion 22 to the direction of locking; Forbid the unlock operation once more of this operating portion 22, so, can prevent effectively that dial-type coded lock 3 is reset to non-operating portion 22 behind the sign indicating number state is moved to the recovery of the direction of locking and is hindered.

And then; The flexible power of directive effect of locking in operating portion 22 upper edges, operating portion 22 is because the operating physical force of unlock operation disappears and to the direction action of locking, owing to adopted such formation; So, operating portion 22 is recovered automatically to the direction of locking as long as handle unclamps from operating portion 22.

Especially, because the handle of operating portion 22 double as shutter door 2 usefulness, so can utilize a series of action to carry out unlock operation and opening operation thereafter swimmingly.

As concrete form; Dial-type coded lock 3 has: bar 31; This bar 31 is loaded to a direction elasticity and is overcome resilient movement during at 30 pairs of sign indicating numbers of dial-type coded lock main body to assigned position and be maintained at said assigned position, and at non-this confining force of removing during to sign indicating number; Action body 4, this action body 4 is reseted holding state through reseting non-dial-type coded lock main body 30 being placed to the sign indicating number state, through moving to other direction to the action of direction and with dial-type coded lock main body 30.With having carried out association by means of the 1st related C of portion between said bar 31 and the said operating portion 22; Thereby non-ly forbidding the unlock operation of said operating portion 22 during to sign indicating number, to sign indicating number the time, allowing this unlock operation; And; With having carried out association by means of the 2nd related D of portion between said action body 4 and the said operating portion 22, thereby follow unlock operation dial-type coded lock main body 30 to be reset to non-to the sign indicating number state to this operating portion 22 behind the sign indicating number.Therefore, bar 31, action body 4 and operating portion 22 are linked rightly.

In addition; Owing to be that holding section 21 is sickle shaped and stretches out, is stuck the relation that portion 11 admits holding section 21 in the above-described embodiment; So can be applied to have the applicable object of such snap-in structure, for example locker etc. directly drives holding section 21.

In this case; Interfere though close 2 o'clock holding sections 21 of door and be stuck portion 11; But because the unlock operation of operating portion 22 is disengaged behind 3 pairs of sign indicating numbers of dial-type coded lock; Holding section 21 flexibly moves to upper lock position, and when door 2 was about to arrive make position, holding section 21 overcame elastic force and once carrying out being fastened in the portion of being stuck 11 after the avoiding interference action through bumping being stuck in the portion 11; As long as therefore realized effectively closing the formation that door 2 just becomes locking state automatically, can make the simplification of operating procedure, the good ease of use of bringing thus have actual effect.

And traction operating portion 22 carries out the avoiding interference action owing to holding section 21 being constituted not, so closed action is carried out trippingly.

Particularly; Holding section 21 is to extend and the top has the member of crooked claw 21a along door 2 the switching direction that is in the close position; Corresponding, can go up through the 11a of the portion that is stuck that above-mentioned snap-in structure is fastened on this claw 21a to be positioned at the deep inside side reliably and realize closure state.

And; If the locking and unlocking device A of this embodiment is applied between door 2 and the casing 1; Do not require that then high precision can assemble dial-type coded lock 3 simply and constitute furniture for accommodation A such as lockers; Can make steady in a long-term, the action reliably of locking and unlocking device A thus, make the ease of use that deposits accommodation device B such as taking-up in that improves effectively such as carrying out personal belongings etc. rapidly, simply become possibility.

In addition, the concrete formation of each several part is not to be merely the formation that above-mentioned embodiment limits.

For example, except door, open and close member also can be a drawer etc., also can dial-type coded lock, operating portion and holding section be set in the casing side, is stuck portion in the setting of open and close member side.

In addition, can constitute also that the portion of being stuck is that sickle shaped stretches out, the holding section is the relation of its admittance.

And then, also can constitute the holding section and be fastened on the casing with opening and closing crossing out of direction quadrature.In this case, when the holding section is formed the reaping hook shape, also can utilize the top not have the member of the bolt shape of claw.

And then, follow unlock operation that dial-type coded lock main body is reset in the non-situation to the sign indicating number state through the 2nd related portion to the operating portion behind the sign indicating number, also comprise the form of being reseted after the unlock operation of having removed operating portion.

Other formation also can be carried out various distortion as long as within the scope that does not exceed aim of the present invention.

The savings of the action force that is produced by spring 124, the 1st illustrated in front rotary body 23 carries out when rotating relatively with the 2nd rotary body 25.Promptly; When operating portion 122 from dial-type coded lock 103 by state to the Figure 17 behind the sign indicating number and Figure 18; By further as Figure 19 and shown in Figure 20 the 1st rotary body 23 is rotated when the side of unblanking is operated, otch 23m moves to the position relative with the claw of confining part 6 61.At this moment, also together rotation of the 2nd rotary body 25.Next, in case be opened like Figure 21 and door 102 shown in Figure 22, checkout gear 7 promptly detects this state and makes restraint device 6 move to restraint position, and therefore, the rotation of the 1st rotary body 23 is restrained.After this, in case the operating physical force of operating portion 122 is disengaged, action body 104 is promptly loaded by spring 130a shown in arrow among Figure 23 and Figure 24 and stretches out, and the 1st rotary body 23 is in the state that restrained device 6 is retrained, only the 2nd rotary body 25 rotations.For this reason, this moment, the 1st rotary body 23 made holding section 121 from the action force of the lockset position of coupler shown in Figure 23 and Figure 24 towards the upper lock position shown in Figure 15 and Figure 16 owing to being compressed to put aside at spring 130a between itself and the 2nd rotary body 25.The 1st rotary body 23 is brought into play function as action force savings member of the present invention.Certainly, it is also harmless in spring 130a, to add required load in advance.When the 1st rotary body 23 is in that the 2nd rotary body 25 rotates with operating portion 122 under the restrained state, shown in figure 24, the pin 122y of operating portion 122 is moved about in the slotted hole 23y of the 1st rotary body 23.

Next, comprise the action of in the part explanation, having stated, the molar behavior of this embodiment is described.

At first, door 102 is in the make position shown in Figure 15 and Figure 16, and dial-type coded lock 103 is in non-during to the sign indicating number state, and the confining force of bar 131 is disengaged, and bar 131 is loaded by spring 132f and is in the turned position, below.At this moment, the operation of operating portion 122 is owing to the 1st related 100C of portion is under an embargo, and holding section 121 is in the upper lock position that is fastened in the portion of being stuck 111.The pin 122y of operating portion 122 is positioned at slotted hole 23y one distolateral of the 1st rotary body 23, confining part 6 since checkout gear 7 detect make position and be maintained at the unconfinement position with respect to the 1st rotary body 23.Next; In case make 103 pairs of sign indicating numbers of dial-type coded lock; Bar 131 promptly moves to the turned position, top and is maintained at this position shown in arrow among Figure 17 owing to the function of dial-type coded lock 103; Baffle element 151 rises, and the formed illegal state of the 1st related 100C of portion is disengaged, and the 2nd rotary body 25 becomes the state that can move with operating portion 122 and action body 104.So; When shown in arrow among Figure 19 and Figure 20, the grip 122a of operating portion 122 being operated; Pin 122y makes its rotation by means of the end of the slotted hole 23y of the 1st rotary body 23 to 23 loadings of the 1st rotary body; Consequently, holding section 121 keeps out of the way out from being stuck portion 111, is lowered to lockset position of coupler from the upper lock position rotation; And utilize the pin 122c comprise the 2nd rotary body 25 and move the slotted hole 104c of body 104, will move body 104 and push and digit wheel is made zero while compress spring 130a at the 2nd interior related 100D of portion.When such making zero, the confining force of bar 131 is disengaged, bar 131 under the effect of spring 132 downwards the turned position rotate.Suppose under this state, to remove the operating physical force of operating portion 122, then the 1st rotary body 23 makes holding section 121 rotate to the upper lock position shown in Figure 15 and Figure 16 once more and gets back to locking state once more, not much else.Corresponding; If continuing to grab grip 122a such as Figure 21 and shown in Figure 22 of operating portion 122 from the state of Figure 19 and Figure 20 opens door 102; Then because the state that the displacement portion 72 of checkout gear 7 is pushed into obtains releasing; So confining part 6 edge as Figure 14 (b) → (a) makes the direction rotation of its claw 61 near the 1st rotary body 23; Thereby the rotation of constraint the 1st rotary body 23 shown in figure 22, i.e. the rotation of holding section 121, and be opened like the accommodation space of Figure 21 and casing shown in Figure 22 101.In case removed operation to operating portion 122; Action body 104 is just loaded to stretching out direction by spring 130a; Because this loading force also is passed on the 2nd rotary body 25 and the operating portion 122, so like Figure 23 and shown in Figure 24, when the 1st rotary body 23 is in restrained member 6 and is retraining the state that can not rotate; The pin 122y of operating portion 122 is along with the action of stretching out of action body 104 is moved about in the slotted hole 23y of the 1st rotary body 23, and the 2nd rotary body 25 is with operating portion 122 rotations simultaneously.At this moment, the spring 124 that is installed between the 1st rotary body 23 and the 2nd rotary body 25 is compressed, and holding section 121 still is maintained at lockset position of coupler, and action body 104 stretches out, and becomes in order to carry out the holding state of reseting of retraction next time.Under this state, even once more operating portion 122 is operated, pin 122y moves about in the slotted hole 23y of the 1st rotary body 23, does not change on the holding section 121.

At last, from the state of Figure 23 and Figure 24 when the make position opposite house 102 shown in Figure 15 and Figure 16 is operated, when having arrived make position; The thrust piece 71 of checkout gear 7 pushes displacement portion 72, and thus, confining part 6 rises to the position shown in Figure 15 and Figure 16; The 1st rotating member 23 is owing to constraint is disengaged; Under the effect of the action force of in spring 124, putting aside, the 1st rotating member 23 holding sections 121 that make as shown in the drawing rotate to upper lock position, consequently; The claw 121a of holding section 121 is fastened on the back side of open circumferential of the portion of being stuck 111, gets back to locking states.At this moment; Restrictions 23k shown in Figure 13 was once promoting baffle element 151 and under claw 151a, was passing through; Be fastened on once more thus on this claw 151a; Even return to the attendant exclusion state after this---desire is operated operating portion 122, and the rotation of the 1st rotary body 23 also suffers restraints and can not operate.

As above, the locking and unlocking device 100A of this embodiment has: the door 102 of casing 101, the open and close member that opens and closes as the opening 11 that is used for this casing 101, be located at dial-type coded lock 103, operating portion 122 and the holding section 121 on the said door 102 and be located at the portion that is stuck 111 on the said casing 101.The locking and unlocking device 100A of this embodiment fastens through making this holding section 121 and this be stuck portion 111, said door 102 is remained on the device of make position.

And said operating portion 122 is after accepting unlock operation, can said holding section 121 be constituted from the mode that upper lock position switches to lockset position of coupler with respect to the said position that is stuck portion 111; At least carried out related with operating portion 122 said dial-type coded lock 103 through the related 100C of portion, 100D; Its interrelational form is: when door 102 closures; In the non-unlock operation of forbidding said operating portion 122 during to sign indicating number, to sign indicating number the time, allow this unlock operation and with thereafter unlock operation interlock and be reset to non-to the sign indicating number state; Said holding section 121 constitutes as follows: the action force of putting aside towards upper lock position when said holding section 121 is disengaged the unlock operation of said operating portion 122 after door 102 is opened is maintained at lockset position of coupler; Moved to the stage of make position once more at said door 102; Said action force is disengaged, and said thus holding section 121 is automatically moved to upper lock position and is fastened on said being stuck in the portion 111.

Like this, behind 103 pairs of sign indicating numbers of dial-type coded lock, operating portion 122 becomes and does not receive to restrict; Next, as long as operating portion 122 is carried out unlock operation, holding section 121 will switch to lockset position of coupler from upper lock position; And dial-type coded lock 103 is reset to non-to the sign indicating number state, open the door 102 after, just can be placed on locking state as long as make it move to make position once more; Therefore, this locking and unlocking device 100A can supply to use with few step.

And; Owing to dial-type coded lock 103 is reset to non-to the sign indicating number state with the operations linkage of operating portion 122; So with, for example, compare to utilize door 102 to reset the situation that the mode of dial-type coded lock 103 constitutes for the relative action of casing 101; Need not dial-type coded lock 103 to be assemblied between casing 101 and the door 102, make and realize effectively that through simple easy assembling the locking and unlocking device 100A of action becomes possibility reliably with good precision.

And then; Even after opening door 102, remove the operating physical force to operating portion 122, holding section 121 also still is maintained at lockset position of coupler, moves to upper lock position in the stage holding section 121 that has moved to make position; Therefore; Even holding section 121 or to be stuck portion 111 are the so-called horizontal sickle shaped members as this embodiment, the closed action that also need not to improve action that precision can avoid holding section 121 and door 102 interferes, and realizes appropriate and reliable closure state and locking states.

In addition; Owing between casing 101 and door 102, be provided with and be used for the checkout gear 7 whether detecting gate 102 is in the close position; So can after whether detecting gate 102 arrives make position reliably, make holding section 121 action again, thereby the switch motion that can positively avoid with door 102 interferes.

Have again; Also be provided with the 1st rotary body 23 and the 1st rotary body 23 is constrained in the confining part 6 that action force is put aside the position; Wherein, the 1st rotary body 23 makes holding section 121 from the action force of lockset position of coupler towards upper lock position as action force savings member savings, and the savings of this action force is 121 because the operation of operating portion 122 and moving to lockset position of coupler from upper lock position in the holding section; After this, carry out before being disengaged after door 102 is opened and to the operating physical force of operating portion 122.Said checkout gear 7 makes holding section 121 under the effect of the action force that the 1st rotary body 23 is put aside, move to upper lock position from lockset position of coupler detecting the confining force of removing said confining part 6 when door 102 has moved to the situation of make position once more.Owing to adopted such formation, so the detection that can make the make position of being undertaken by checkout gear 7 links with releasing to the action force of holding section 121 rightly.

Have again; Owing to checkout gear 7 is comprised be located at the displacement portion 72 of door 102 sides; This displacement portion 72 is carried out displacement through contacting with the thrust piece 71 that is located at casing 101 sides; Thereby make confining part 6 move to the unconfinement position with respect to the 1st rotary body 23 from restraint position, particularly the 102b of side contacts, separates on the limit of the rotating side of door 102 with this thrust piece 71 owing to make this displacement portion 72, so can embed and obtain exactly mechanical displacement compactly.

In addition; Because the related 100C of portion among the said related 100C of portion, the 100D has been configured to ratchet structure; Promptly utilize the unlock operation of operating portion 122 dial-type coded lock 103 to be reset to non-to behind the sign indicating number state; Under the situation that this unlock operation is disengaged, allow the recovery action of operating portion 122 to the direction of locking; INHIBITORY-gate is closed the unlock operation once again of this later operating portion 122, so can prevent effectively that dial-type coded lock 103 is reset to non-operating portion 122 after the sign indicating number state is moved to the recovery of the direction of locking and is hindered.

And then, the flexible power of directive effect of locking in operating portion 122 upper edges, because the operating physical force of unlock operation disappears, this operating portion 122 is to the direction action of locking.Owing to adopted such formation,, operating portion 122 is recovered automatically to the direction of locking as long as handle unclamps from operating portion 122.
