Patent documentation 1: Japanese Patent Publication 6-60544 communique

Summary of the invention

, in locking and unlocking device in the past, when opening a device such as grade, need to make digit wheel to 2 such steps operations of the operation of the operation of code and rotation handgrip.And, add the operation of reseting digit wheel after opening the door, it is more that step becomes.In this locking and unlocking device in the past, as patent documentation 1, the idea that digit wheel is made zero is combined into rightly, can expect to make step to simplify.Yet, handgrip is rotated after making zero, owing to having added, making the operation of handgrip return, the reasons such as operation that operate operation that different handles opens door, handgrip are carried out when door is closed, operation is still miscellaneous.

On the one hand, in assembling between door and casing with being attached to actuating strut on pull-type coded lock etc. to utilize door for a relative action for casing, pull-type coded lock to be reset, also can become the effective means of automatically reseting minimizing operating procedure by pull-type coded lock, but in the situation that adopt such formation, while assembling pull-type coded lock between door and casing, need precision, require high-precision assembling comparatively speaking, and need to consider separately how to make its long-term stability, action reliably.

On the other hand, in order to remove the operation of handgrip at closing time from, operating portion is not operated, in the action of closing the door, the formation of the holding section automatic fastening of reveal on the engaged part of casing side also can be considered to a kind of effective means, but, in the situation that holding section is for example horizontal reaping hook lock (Sickle Ingot タイプ) member, because the on-off action of door and the action of holding section interfere, so must make it link rightly.

The present invention is conceived to such problem and makes, the furniture for accommodation that its object is to provide a kind of locking and unlocking device and has applied this locking and unlocking device, this locking and unlocking device can simply easily be assemblied in pull-type coded lock between casing and open and close member it is moved reliably, and can carry out etc. with few on the whole step the locking and unlocking of open and close member.

For solving the means of problem

In order to reach such object, the present invention has adopted following means.

That is, locking and unlocking device of the present invention has: for opening and closing the open and close member of the opening of casing and this casing; Be located at pull-type coded lock, operating portion and the holding section of any one party of described casing or described open and close member; With the engaged part that is located at any the opposing party of described casing or described open and close member, by making described holding section and engaged part fasten and described open and close member is remained on to make position, it is characterized in that: described operating portion is accepted unlock operation and described holding section is switched to lockset position of coupler with respect to the position of described engaged part from upper lock position; Described pull-type coded lock passes through associated portion at least by associated with described operating portion, its interrelational form is, non-ly forbidding the unlock operation of described operating portion during to code, allow described unlock operation and with unlock operation interlock thereafter and be reset to non-to code state when to code; Described holding section is constituted as, after the unlock operation that described operating portion is carried out is disengaged described open and close member till again moving to make position during be automatically moved to upper lock position and engage with described engaged part.

In the locking and unlocking device so forming, when open and close member is in the close position, pull-type coded lock is non-during to code, the unlock operation of operating portion is forbidden by pull-type coded lock, the situation that lockset position of coupler is moved in holding section can not occur.Next, once pull-type coded lock by code, is disengaged for the illegal state of operating portion, unlock operation is allowed.Once operating portion has been carried out unlock operation, holding section moves to lockset position of coupler from upper lock position, becomes the state that can open open and close member.In addition, follow unlock operation, pull-type coded lock is reset to non-to code state.And, after open and close member is opened, as long as make it again move to make position, just can only with this, move holding section is fastened on engaged part.Now, due to pull-type coded lock in non-to code state, the unlock operation of operating portion is prohibited, so as long as pull-type coded lock, not by code, just can not operate operating portion again.

Like this, after pull-type coded lock is to code, operating portion becomes and is not subject to restrict, next, as long as operating portion is carried out to unlock operation, holding section just can be switched to lockset position of coupler from upper lock position, and pull-type coded lock is reset to non-to code state, and then, as long as make open and close member move to make position, just can be placed on locking state, thus this locking and unlocking device can with few step for.

And, because the operations linkage with operating portion is reset to pull-type coded lock non-to code state, so with, for example, to utilize open and close member to reset for the relative action of casing the situation that the mode of pull-type coded lock forms, compare, without the precision with good, pull-type coded lock is embedded between casing and open and close member, by the simple assembling locking and unlocking device that realization is moved reliably effectively that is easy to, becomes possibility.

In order not make operating portion be reset to and non-ly be hindered to the recovery action of the direction of locking after to code state at pull-type coded lock, be preferably, described associated portion forms ratchet structure as follows: in the situation that pull-type coded lock is non-because the unlock operation of operating portion is reset to, this unlock operation after code state is disengaged, allow operating portion make progress lock side to recovery action, forbid the unlock operation again of this operating portion.

In order simplifying, operating portion have been carried out to the step after unlock operation, to be preferably, formed as follows operating portion: make elastic force along locking directive effect on this operating portion, due to the operating physical force disappearance of unlock operation, thereby this operating portion has made progress lock side to action.

In order to make unlock operation and the co-operating swimmingly of the opening operation after it, be preferably operating portion and double as the handle that open and close member is opened and closed to use.

As concrete embodiment, can enumerate such example: pull-type coded lock has bar and action body, wherein, described bar is loaded to a direction elasticity, it overcomes resilient movement to assigned position and is maintained at described assigned position during to code in pull-type coded lock main body, and at non-this confining force of removing during to code; Described action body is reseted holding state by pull-type puzzle lock main body weight being made as to non-pull-type coded lock main body being placed in to code state, by moving to other direction to a direction action; By between described bar and described operating portion, by means of the 1st associated portion, carry out associated, thereby non-ly forbidding the unlock operation of described operating portion during to code, when to code, allowing this unlock operation, and, associated by carrying out by means of the 2nd associated portion between described action body and described operating portion, thereby follow, to the unlock operation of this operating portion after code, pull-type puzzle lock main body weight is made as non-to code state.

As for being applied in the structure on the furniture for accommodation such as locker, be preferably, described holding section and engaged part become that any one party is that sickle shaped stretches out and the opposing party by the relation of its receiving.

In this case, when being carried out to closure, open and close member make it engage with the interference of engaged part in order to avoid rightly holding section, preferably form as follows holding section: the unlock operation of operating portion is disengaged after pull-type coded lock is to code, thus, holding section resilient movement is to upper lock position, avoiding interference action is carried out by overcoming elastic force with engaged part butt before being about to arrive make position at open and close member in described holding section temporarily, then engages with engaged part.

For action is now carried out swimmingly, be preferably, holding section is configured to and can carries out avoiding interference action and traction operating portion not.

Such formation especially can be applied to such device very suitably: any one party of holding section or engaged part is the member that switching direction is extended, top has crooked claw of the open and close member along in the close position.

And, if by the locking and unlocking application of installation of present embodiment between open and close member and casing, do not require that precision can carry out locking and unlocking device to assemble simply, reliably, make its action steady in a long-term, the ease of use that makes effectively to improve the accommodation device of having applied this locking and unlocking device becomes possibility.

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

That is, locking and unlocking device of the present invention has: casing; For opening and closing the open and close member of the opening of this casing; Be located at pull-type coded lock, operating portion and the holding section of any one party of described casing or described open and close member; With the engaged part that is located at any the opposing party of described casing or described open and close member, by making Yu Gai engaged part, this holding section fasten and described open and close member is remained on to make position, it is characterized in that: described operating portion is accepted unlock operation and described holding section is switched to lockset position of coupler with respect to the position of described engaged part from upper lock position; Described pull-type coded lock passes through associated portion at least by associated with described operating portion, its interrelational form is, at least when open and close member is closed, in the non-unlock operation of forbidding described operating portion during to code, when to code, allow this unlock operation and with unlock operation interlock thereafter and be reset to non-to code state; Described holding section is constituted as, when the unlock operation of described operating portion is disengaged after open and close member is opened, be maintained at lockset position of coupler putting aside under the state of the action force of upper lock position, the stage that has again moved to make position at described open and close member is automatically moved to upper lock position because described action force is disengaged, and engages with described engaged part.

In the device so forming, when open and close member is in the close position, pull-type coded lock is non-during to code, the unlock operation of operating portion is forbidden by pull-type coded lock, the situation that holding section moves to lockset position of coupler can not occur.Next, once pull-type coded lock by code, is disengaged for the illegal state of operating portion, unlock operation is allowed.Once operating portion has been carried out unlock operation, holding section moves to lockset position of coupler from upper lock position, becomes the state that open and close member can be opened.In addition, follow unlock operation, pull-type coded lock is reset to non-to code state.After opening, even be disengaged for the unlock operation of operating portion, holding section is also being put aside towards the action force of upper lock position and is being maintained on lockset position of coupler.And, make open and close member again move to stage of make position, holding section because put aside action force is disengaged automatic fastening on engaged part.Now, due to pull-type coded lock in non-to code state, the unlock operation of quiescing portion, so as long as pull-type coded lock, not by code, just can not operate operating portion again.

Like this, after pull-type coded lock is to code, operating portion becomes and is not subject to restrict, next, as long as operating portion is carried out to unlock operation, holding section just can be switched to lockset position of coupler from upper lock position, and pull-type coded lock is reset to non-to code state, after opening open and close member, as long as again make open and close member move to make position just can be placed on locking state, so this locking and unlocking device can with few step for.

And, because the operations linkage with operating portion is reset to pull-type coded lock non-to code state, so with, for example, to utilize open and close member to reset for the relative action of casing the situation that the mode of pull-type coded lock forms, compare, without the precision with good, pull-type coded lock is embedded between casing and open and close member, making becomes possibility by the simple assembling locking and unlocking device that realization is moved reliably effectively that is easy to.

And then, after opening open and close member, even if remove the operating physical force to operating portion, holding section is still maintained at lockset position of coupler, because the stage holding section having moved to make position moves to upper lock position, thus irrelevant with the form of holding section or engaged part, even if holding section or engaged part are the forms such as sickle shaped or bolt shape, also without improving precision, just can avoid the interference in action of holding section and open and close member, guarantee appropriately and action reliably.

In this case, in the situation of the non-unlock operation of quiescing portion during to code, also comprise such structure: even operating portion is operated during to code non-, operating portion is just idle running also, and does not switch the position of holding section.

In order to detect reliably open and close member, whether arrive make position, be preferably, between casing and open and close member, be provided with the checkout gear that whether is positioned at make position for detection of open and close member.

For the detection of the make position that makes to be undertaken by checkout gear with the releasing of the action force of holding section is linked rightly, preferably make locking and unlocking device there is action force savings member and this action force savings member is constrained in to the confining part that action force is put aside position, described action force savings member, in holding section, due to the operation of operating portion, from upper lock position, to lockset position of coupler, move, afterwards open and close member till being opened, the operating physical force of operating portion being disengaged during, savings make this holding section from lockset position of coupler the action force towards upper lock position; Preferred described locking and unlocking device is configured to, when described checkout gear detects open and close member and has again moved to the situation of make position, remove the confining force of described confining part, the action force that utilizes described action force savings member to put aside makes holding section move to upper lock position from lockset position of coupler.

Concrete embodiment as checkout gear, can enumerate such device: the displacement portion that comprises any one party that is located at casing or open and close member, this displacement portion, by contacting and be subjected to displacement with any the opposing party of casing or open and close member, makes confining part from constrained, move to unconfinement position for action force savings member.

In order not make operating portion be reset to and non-ly be hindered to the recovery action of the direction of locking after to code state at pull-type coded lock, be preferably, described associated portion forms ratchet structure as follows: in the situation that pull-type coded lock is non-because the unlock operation of operating portion is reset to, this unlock operation after code state is disengaged, allow operating portion make progress lock side to the unlock operation once again of this operating portion after being closed of recovery action, INHIBITORY-gate.

In order simplifying, operating portion have been carried out to unlock operation step afterwards, to be preferably, formed as follows operating portion: make elastic force along locking directive effect on operating portion, due to the operating physical force disappearance of unlock operation, thereby this operating portion has made progress lock side to action.

In order to make unlock operation and the co-operating swimmingly of the opening operation after it, preferred operations portion doubles as the handle that open and close member is opened and closed to use.

As concrete embodiment, can enumerate such example: pull-type coded lock has bar and action body, wherein, described bar is loaded to a direction elasticity, it overcomes elasticity and moves to and be maintained at assigned position during to code in pull-type coded lock main body, and at non-this confining force of removing during to code, described action body is non-to code state by pull-type puzzle lock main body weight being made as to a direction action, by pull-type coded lock main body being placed in to other direction action, resets holding state; By between described bar and described operating portion, by means of the 1st associated portion, carry out associated, thereby non-ly forbidding the unlock operation of described operating portion during to code, when to code, allowing this unlock operation, and, associated through carrying out by means of the 2nd associated portion between described action body and described operating portion, thereby follow, to the unlock operation of this operating portion after code, pull-type puzzle lock main body weight is made as non-to code state.

As for being applied in the structure on the furniture for accommodation such as locker, described holding section and engaged part are applicable to following relation very much: any one party is that sickle shaped or bolt shape are stretched out and the opposing party is received.

Such formation especially can be applied to such device very suitably: the member that the direction that any one party of holding section or engaged part is the switching direction quadrature along the open and close member with in the close position is extended.

And, if by the locking and unlocking application of installation of present embodiment between open and close member and casing, do not require precision can be simply, the assembling unlocking apparatus of locking reliably, it is moved steadily in the long term, and the ease of use that makes effectively to improve the accommodation device of having applied this locking and unlocking device becomes possibility.

The effect of invention

The specific embodiment

(the 1st embodiment)

Below, with reference to Fig. 1～Fig. 6, the 1st embodiment of the present invention is described.

Fig. 1～Fig. 3 has represented to apply the accommodation device B of the locking and unlocking device A of present embodiment.This accommodation device B open and close casing 1 accommodation space position configuration as the door 2 of open and close member, locking and unlocking device A has been applied between this door 2 and this casing 1.This locking and unlocking device A has embedded holding section 21 and pull-type coded lock 3 in door 2, in casing 1 side, be provided with engaged part 11, as long as door 2 is pushed and just makes holding section 21 be fastened on engaged part 11 to form locking state, thus door 2 is remained on to the position with respect to casing 1 closure with locking states, by making to be located at the 3 pairs of codes of pull-type coded lock on door 2, can engagement release portion 21 with engaging of engaged part 11, door 2 be opened, the action that grip 22a is rotated of the opening action that utilization conduct door 2 is thereafter initial, reset pull-type coded lock 3 to code state.

Once illustrate.Door 2 is to can be opened and closed to be bearing on the side plate 12 of casing 1 by means of the be fixed 2a of limit portion of side of linkage H, on the front surface of side plate 12 that is positioned at hinge H opposition side, be formed with towards the stage portion 12a of the place ahead depression, when door 2 is closed, the thickness of the 2b of limit portion of the rotating side of door 2 is partly received in the stage portion 12a of this depression.On the front surface of door 2, be provided with the operating portion 22 forming can carry out the mode of unlock operation.This operating portion 22 has and can catch the grip 22a operating by enough fingers, it has the function that can grab the handle that it opens door 2 concurrently, in this embodiment, by use, point and catch it to make roughly 90 degree of its (direction of unblanking) rotation left, engagement release portion 21 engages with engaged part 11, as long as unclamp, points it just because of elasticity (direction of locking) rotation to the right.

Holding section 21 is falculate members, the state that it rearward stretches out near the back side 2b of portion of the limit of the rotating side from door 2, in the mode that can move up and down, be set up, engaged part 11 is members of slit-shaped, it is arranged on position corresponding with holding section 21 in block face 12x, and this block face 12x is positioned at the deep inside that is formed on the described stage portion 12a on casing 1.Falculate holding section 21 is tabular components that are roughly L font of making of materials such as steel, and top forms reclinate claw 21a.

And, as shown in Fig. 3 and Fig. 6 etc., at the back side of door 2, can move up and down and dispose movable link 23, be formed with it described holding section 21 in a part for this movable link 23, the cam part 22b that makes to be located at the back side of operating portion 22 has been fastened on this movable link 23.; cam part 22b is the locational member that is configured in the soffit 23a of supporting movable link 23; at operating portion 22, upwards lock under the state of solid line in the Fig. 6 (a) in direction rotation; it is not mentioned movable link 23; upper lock position after holding section 21 is maintained at and falls; once and operating portion 22 is by the direction operation of unblanking shown in arrow in figure, it is just mentioned the soffit 23a of movable link 23 by cam part 22b, makes holding section 21 move upward to lockset position of coupler.

As shown in Fig. 3 waits, pull-type coded lock 3 makes bar 31 and action body 4 stretch out to the direction at the back side towards operating portion 22 from box-like pull-type coded lock main body 30.

Once illustrate.The position that drifts out fulcrum n of bar 31 by spring 32 toward the direction, be that downward direction loads, pull-type coded lock 3 has such function: when to code, bar 31 is remained on the approximate horizontal shown in Fig. 4 above turned position, and at non-this confining force of removing during to code.If there is no other interferences, the bar 31 that confining force has been disengaged is because spring 32 moves to the turned position, below shown in Fig. 3.

In addition, action body 4 is butts in the inside of pull-type coded lock main body 30 with spring 30a to the member that stretches out direction loading, once top is pushed to a direction, it will be put aside elastic force get off one side on one side and move to the direction in retraction box body 30, and once by push-on force releasing, it will stretch out to other direction.

Pull-type coded lock main body 30 is configured to, and at above-mentioned action body 4, from box body 30, stretches out the digit wheel state that Shi Buhui affects pull-type coded lock 3, and the digit wheel of pull-type coded lock 3 should be made zero in above-mentioned action body 4 retraction box bodys 30 time.; once digit wheel is by code; just bar 31 is rotated to from the state of Fig. 3 Fig. 4 level turned position, top and hold it in this position; and once motion body 4 is pushed into the position of Fig. 5 by the state from Fig. 4; digit wheel is just made zero; the confining force of bar 31 is just disengaged, and bar 31 is because spring 32 trends towards from the state of Fig. 5 towards the turned position, below shown in Fig. 3.About pull-type coded lock 3 reset the contents such as structure, due to various structures be known, so the explanation of internal construction is just omitted and has not been carried.

And, will between described bar 31 and described operating portion 22, by means of the 1st associated C of portion, carry out association, according to digit wheel code state is switched between operable state and attendant exclusion state operating portion 22.The 1st associated portion consists of following part: be positioned at the rotation end of described bar 31, the baffle element 51 of lifting with the interlock of rotational action up and down of this bar 31; Attended operation portion 22 upwards lock side to rotary manipulation and to the moving body 52 that approaches direction (approaching the direction of the pull-type coded lock main body 30) movement of described baffle element 51.And, they are interrelated as follows: non-during to code under the state of Fig. 3 of baffle element 51 in falling position, when moving body 52 is wanted the unlock operation of attended operation portions 22 and when mobile, baffle element 51 stops that with its sidewall 51a moving body 52 moves; When to code, baffle element 51 moves under the state of lifting position with the rotation of bar 31 as shown by the arrows in Figure 4 simultaneously, when moving body 52 is wanted the unlock operation of attended operation portions 2 and when mobile, baffle element 51 allows moving bodys 52 to move.Consequently, moving body 52 can move to the position under the soffit 51b of lower potential baffle element 51 as shown in Figure 5.

In addition, associated by carrying out by means of the 2nd associated D of portion between described action body 4 and described operating portion 22, according to the operating conditions of operating portion 22, pull-type coded lock main body 30 is made zero.The 2nd associated D of portion is by the described moving body 52 that the rotary manipulation of attended operation portion 22 is moved to the direction that approaches pull-type coded lock main body 30, be installed to be formed on described action body 4 to stretch out the face that erects 4a on end upper and form.And, carry out as follows association: the unlock operation of attended operation portion 22 direction as shown in arrow in Fig. 6 (b), makes to move body 4 retractions by means of moving body 52.

In addition, as shown in Fig. 3 and Fig. 6 (b) etc., be configured to, the position that drifts out center of rotation from the back side of operating portion 22 is extended with axle 22c, this axle 22c is inserted in the slotted hole 52c of the above-below direction being located on moving body 52, by this axle 22c and this slotted hole 52c, make the rotary manipulation of operating portion 22 and the advance and retreat of moving body 52 action interlock.

In addition, between movable link 23 and near the fixed component it 24, elasticity is provided with spring 24a, and this spring 24a gives movable link 23 to fall the elasticity of direction.This spring 24a is bringing into play the effect that (direction of locking) pressed towards below by holding section 21.In addition, due to the spring 30a acting on action body 4, as shown in Figure 6 (b), on operating portion 22, effect has the elastic force of the rightabout towards arrow---direction of locking---, and operating portion 22 can make progress lock side to action because being input to the operating physical force disappearance of the direction of unblanking of operating portion 22.Once upwards lock side is to movement for operating portion 22, movable link 23 is just fallen along the opposite direction of the arrow shown in Fig. 6 (a) under the effect of spring 24a, and holding section 21 returns to upper lock position.When the external force making progress at closing time that will illustrate after the 21 side effects of holding section, on one side not traction operating portion 22 and the Compress Spring 24a action that moves upward on one side of movable link 23.

Under state shown in the moving body 52 that forms the 1st associated C of portion Fig. 5 after unlock operation, become the state slipping under baffle element 51, this is described above.And, when the unlock operation due to operating portion 22, digit wheel is reset to non-during to code state, because bar 31 rotates downwards, baffle element 51 is loaded to falling direction, with removed operating portion 22 operation time move the motion that moving body 52 in the extend action of body 4 under spring 30a effect wants to return origin-location and interfere.So, on the position contacting with baffle element 51, be provided with the spigot surface 52d of curve form in moving body 52, moving body 52 can be on one side mentioned on one side from it baffle element 51 by returning to and moving the corresponding position of the extended position of body 4 along this spigot surface 52d.Bar 31 and baffle element 51 are offset to the position of falling of Fig. 3 therefrom.After this, if digit wheel not by again to code, the unlock operation of this operating portion 22 is just prohibited, therefore the 1st so associated C of portion can be described as ratchet structure.

Next the action of present embodiment is described.

First, door is 2 in the make position shown in Fig. 7 (a), if pull-type coded lock 3 in non-to code state, the confining force of bar 31 is disengaged, bar 31 is loaded by spring 32 and in turned position, below.The now operation of operating portion 22 forbidden by the 1st associated C of portion, and holding section 21 is in being fastened on the upper lock position on engaged part 11.Next, once make 3 pairs of codes of pull-type coded lock, bar 31 moves to turned position, top and is maintained at this position because of the function of pull-type coded lock 3 as shown in arrow in Fig. 7 (b), and the illegal state that the 1st associated C of portion forms is disengaged.For this reason, as shown in Figure 8 (a), by the grip 22a of operating portion 22 is operated, holding section 21 rises to the lockset position of coupler engaging of removing with engaged part 11, and action body 4 is pushed and digit wheel is made zero by the 2nd associated D of portion.If open door 2 under this state, as shown in Figure 8 (b) shows, the accommodation space of casing 1 is opened.When such making zero, the confining force of bar 31 is disengaged, bar 31 under the effect of spring 32, trend towards towards below turned position rotate.Once remove the operation to operating portion 22, operating portion 22 upwards locks direction rotation because of elasticity, follows in this, holding section 21 is lowered to the upper lock position shown in Fig. 9.The same when state of pull-type coded lock 3 now and Fig. 7 (a), the 1st associated C of portion becomes attendant exclusion state again, and action body 4 stretches out and is transferred in order to carry out the holding state of reseting of retraction next time.

When as shown in Figure 9 by door 2 closure, because holding section 21 is positioned at upper lock position, if so at that towards make position, can interfere with the opening edge of engaged part 11, even but because holding section 21 at operating portion 22 in operable state not also traction operating portion 22 and by means of movable link 23 Compress Spring 24a move upward on one side (with reference to Fig. 6 (a)) on one side not, so in order to avoid the interference with engaged part 11, holding section 21 was once overcoming the elasticity of spring 32, cross the opening edge of engaged part 11 as shown in arrow in this figure after, under the effect of spring 32, again move downwards, return to the upper lock position of Fig. 7 (a).Now, the claw 21a of holding section 21 is fastened on the back side of the open circumferential of engaged part 11, and pull-type coded lock 3 maintains the state of making zero.

As mentioned above, the locking and unlocking device of present embodiment have as for open and close casing 1 and this casing 1 opening 11 open and close member door 2, be arranged on pull-type coded lock 3, operating portion 22 and the holding section 21 on described door 2 and be arranged on the engaged part 11 on described casing 1, by 21Yu Gai engaged part, this holding section 11 is fastened, described door 2 is remained on to make position.

And, described operating portion 22 is configured to: can be after accepting unlock operation described holding section 21 be switched to lockset position of coupler with respect to the position of described engaged part 11 from upper lock position; By the associated C of portion, D, described pull-type coded lock 3 is at least carried out associated with operating portion 22, its interrelational form is: in the non-unlock operation of forbidding described operating portion 22 during to code, allow this unlock operation and with unlock operation interlock thereafter and be reset to non-to code state when to code; Described holding section 21 is configured to: after the unlock operation of described operating portion 22 is disengaged, described door 2 is automatically moved to upper lock position in the time before again moving to make position and is fastened on described engaged part 11.

Like this, after 3 pairs of codes of pull-type coded lock, operating portion 22 becomes and is not subject to restrict, next as long as operating portion 22 is carried out to unlock operation, holding section 21 just can be switched to lockset position of coupler from upper lock position, and pull-type coded lock 3 is reset to non-to code state, and, as long as make door 2 move to make position and just can become locking state, therefore, this locking and unlocking device A can by few step for.

And, because the operations linkage with operating portion 22 is reset to pull-type coded lock 3 non-to code state, so with, for example, situation about forming in the mode of utilizing the relative action of 2 pairs of casings 1 of door to reset pull-type coded lock 3 is compared, without pull-type coded lock 3 is assemblied between casing 1 and door 2 with good precision, make the locking and unlocking device A that effectively realizes action reliably by simple easy assembling become possibility.

In addition, because the associated C of portion in the described associated C of portion, D adopts ratchet structure, that is: pull-type coded lock 3 due to the unlock operation of operating portion 22 is reset to non-to code state after, in the situation that this unlock operation is disengaged, allow operating portion 22 upwards lock side to recovery action, forbid the unlock operation again of this operating portion 22, so, can effectively prevent pull-type coded lock 3 be reset to non-to operating portion after code state 22 upwards lock side to recovery action hindered.

And then, on operating portion 22, along locking the flexible power of directive effect, operating portion 22 is because the operating physical force disappearance of unlock operation makes progress lock side to action, owing to having adopted such formation, so as long as handle unclamps from operating portion 22, just can make operating portion 22 automatically make progress lock side to recovery.

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

As concrete form, pull-type coded lock 3 has: bar 31, this bar 31 is loaded to direction elasticity and overcomes resilient movement to assigned position and be maintained at described assigned position when 30 pairs of codes of pull-type coded lock main body, and at non-this confining force of removing during to code; Action body 4, this action body 4 is by reseting non-pull-type coded lock main body 30 to code state, by pull-type coded lock main body 30 being placed in and reseting holding state to other direction action to a direction action.To between described bar 31 and described operating portion 22, by means of the 1st associated C of portion, carry out association, thereby non-ly forbidding the unlock operation of described operating portion 22 during to code, when to code, allowing this unlock operation, and, to between described action body 4 and described operating portion 22, by means of the 2nd associated D of portion, carry out association, thereby follow, to the unlock operation of this operating portion 22 after code, pull-type coded lock main body 30 has been reset to non-to code state.Therefore, can make bar 31, action body 4 and operating portion 22 link rightly.

In addition, owing to being in the above-described embodiment the relation that holding section 21 is that sickle shaped stretches out, receive 11Jiang holding section, engaged part 21, so can be applied to have the applicable object of such snap-in structure, such as locker etc., directly holding section 21 be driven.

In this case, although closing door 21He engaged part, 2 o'clock holding sections 11 interferes, but because the unlock operation of operating portion 22 after 3 pairs of codes of pull-type coded lock is disengaged, holding section 21 flexibly moves to upper lock position, when door 2 is about to arrive make position, holding section 21 overcomes elastic force and was once carrying out being fastened on engaged part 11 after avoiding interference action by touching on engaged part 11, therefore as long as effectively realized, close door 2 and just automatically become the formation of locking state, can make the simplification of operating procedure, the good ease of use of bringing thus has actual effect.

And, owing to holding section 21 being configured to not traction operating portion 22, carry out avoiding interference action, so can make closed action carry out trippingly.

Particularly, holding section 21 is to extend and top has the member of crooked claw 21a along the switching direction of door 2 in the close position, corresponding, can this claw 21a be fastened on be reliably positioned at by above-mentioned snap-in structure the upper closure state of realizing of engaged part 11a of deep inside side.

And, if the locking and unlocking device A of present embodiment is applied between door 2 and casing 1, do not require that high precision can assemble simply pull-type coded lock 3 and form the furniture for accommodation A such as lockers, can make thus that locking and unlocking device A is steady in a long-term, action reliably, making effectively to improve allly becomes possibility if carry out rapidly, simply the ease of use that deposits the accommodation device B such as taking-up in of personal belongings etc.

In addition, the formation that the concrete formation of each several part not only limits for above-mentioned embodiment.

For example, except door, open and close member can be also drawer etc., also can pull-type coded lock, operating portion and holding section be set in casing side, in open and close member side, engaged part is set.

In addition, also can form that engaged part is that sickle shaped stretches out, holding section is the relation of its receiving.

And then, also can be configured to holding section and be fastened on casing with opening and closing crossing out of direction quadrature.In this case, when holding section is formed to reaping hook shape, also can utilize top there is no the member of the bolt shape of claw.

And then, by the 2nd associated portion, follow and the unlock operation of the operating portion after code is made as pull-type puzzle lock main body weight non-in the situation of code state, also comprise the form being reset after the unlock operation of having removed operating portion.

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

The savings of the action force being produced by spring 124, carries out when above, illustrated the 1st rotary body 23 is with the relative rotation of the 2nd rotary body 25.; when operating portion 122 from pull-type coded lock 103 by the state of the Figure 17 to code and Figure 18; while further being operated to the side of unblanking as shown in FIG. 19 and 20, the 1st rotary body 23 is rotated, and otch 23m moves to the position relative with the claw 61 of confining part 6.Now, also together rotation of the 2nd rotary body 25.Next, once door 102 is opened as shown in Figure 21 and Figure 22, checkout gear 7 detects this state and makes restraint device 6 move to constrained, and therefore, the rotation of the 1st rotary body 23 is restrained.After this, once the operating physical force of operating portion 122 is disengaged, action body 104 is loaded and stretches out by spring 130a as shown in arrow in Figure 23 and Figure 24, the state that the 1st rotary body 23 retrains in restrained device 6, only the 2nd rotary body 25 rotations.For this reason, now the 1st rotary body 23 due to spring 130a between itself and the 2nd rotary body 25 compressed put aside make holding section 121 from the lockset position of coupler shown in Figure 23 and Figure 24 the action force towards the upper lock position shown in Figure 15 and Figure 16.The 1st rotary body 23 is brought into play function as action force savings member of the present invention.Certainly, in spring 130a, add in advance required load also harmless.When the 2nd rotary body 25 rotates together with operating portion 122 under restrained state at the 1st rotary body 23, as 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 having stated in part explanation, the molar behavior of present embodiment is described.

First, door is 102 in the make position shown in Figure 15 and Figure 16, and pull-type coded lock 103 is in non-during to code state, and the confining force of bar 131 is disengaged, and bar 131 is loaded by spring 132f and in turned position, below.Now, the operation of operating portion 122 is because the 1st associated 100C of portion is prohibited, and holding section 121 is in being fastened on the upper lock position on engaged part 111.The pin 122y of operating portion 122 is positioned at slotted hole 23y one distolateral of the 1st rotary body 23, and confining part 6 is maintained at unconfinement position because checkout gear 7 detects make position with respect to the 1st rotary body 23.Next, once make 103 pairs of codes of pull-type coded lock, bar 131 moves to turned position, top and is maintained at this position as shown in arrow in Figure 17 due to the function of pull-type coded lock 103, baffle element 151 rises, the formed illegal state of the 1st associated 100C of portion is disengaged, and the 2nd rotary body 25 becomes the state that can move together with operating portion 122 and action body 104.So, when the grip 122a of operating portion 122 being operated as shown in arrow in Figure 19 and Figure 20, pin 122y makes its rotation by means of one end of the slotted hole 23y of the 1st rotary body 23 to the 1st rotary body 23 loadings, consequently, 121Cong engaged part, holding section 111 keeps out of the way out, from upper lock position rotation, be lowered to lockset position of coupler, and utilize the slotted hole 104c of the pin 122c comprise the 2nd rotary body 25 and action body 104 at the 2nd interior associated 100D of portion, on one side Compress Spring 130a one side action body 104 is pushed and digit wheel is made zero.When such making zero, the confining force of bar 131 is disengaged, bar 131 under the effect of spring 132 downwards turned position rotate.Suppose to remove the operating physical force of operating portion 122 under this state, the 1st rotary body 23 makes holding section 121 again rotate to the upper lock position shown in Figure 15 and Figure 16 and again gets back to locking state, not much else.Corresponding, if continue to grab the grip 122a of operating portion 122 opens door 102 as shown in Figure 21 and Figure 22 from the state of Figure 19 and Figure 20, the state being pushed into due to the displacement portion 72 of checkout gear 7 is removed, so confining part 6 as Figure 14 (b) → (a) along making its claw 61 approach the direction rotation of the 1st rotary body 23, thereby retrain as shown in figure 22 the rotation of the 1st rotary body 23, be the rotation of holding section 121, and the accommodation space of casing 101 is opened as shown in Figure 21 and Figure 22.Once remove the operation to operating portion 122, action body 104 is just loaded to stretching out direction by spring 130a, because this loading force is also passed on the 2nd rotary body 25 and operating portion 122, so as shown in Figure 23 and Figure 24, at the 1st rotary body 23 when restrained member 6 is retraining not revolvable state, the pin 122y of operating portion 122 is along with the extend action of action body 104 is moved about in the slotted hole 23y of the 1st rotary body 23, and the 2nd rotary body 25 rotates together with operating portion 122 simultaneously.Now, the spring 124 being installed between the 1st rotary body 23 and the 2nd rotary body 25 is compressed, and holding section 121 is still 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 if again operating portion 122 is operated, pin 122y moves about in the slotted hole 23y of the 1st rotary body 23, on holding section 121, does not change.

Finally, while operating to the make position opposite house 102 shown in Figure 15 and Figure 16 from the state of Figure 23 and Figure 24, when having arrived make position, the thrust piece 71 of checkout gear 7 pushes displacement portion 72, thus, confining part 6 rises to the position shown in Figure 15 and Figure 16, the 1st rotating member 23 is because constraint is disengaged, under the effect of the action force of putting aside in spring 124, the 1st rotating member 23 holding section 121 that makes as shown in the drawing rotates to upper lock position, consequently, the claw 121a of holding section 121 is fastened on the back side of open circumferential of engaged part 111, get back to locking states.Now, limiting unit 23k shown in Figure 13 was once promoting baffle element 151 and was passing through under claw 151a, again be fastened on thus on this claw 151a, even if return to after this attendant exclusion state---wish operates 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 present embodiment has: casing 101, as the door 102 of the open and close member for the opening 11 of this casing 101 is opened and closed, be located at pull-type coded lock 103, operating portion 122 and the holding section 121 on described 102 and be located at the engaged part 111 on described casing 101.The locking and unlocking device 100A of present embodiment is by 121Yu Gai engaged part, this holding section 111 is fastened, and described door 102 is remained on to the device of make position.

And described operating portion 122 is that the mode described holding section 121 can be switched to lockset position of coupler with respect to the position of described engaged part 111 from upper lock position after accepting unlock operation forms; By the associated 100C of portion, 100D, described pull-type coded lock 103 has at least been carried out associated with operating portion 122, its interrelational form is: when door 102 is closed, in the non-unlock operation of forbidding described operating portion 122 during to code, when to code, allow this unlock operation and with unlock operation interlock thereafter and be reset to non-to code state; Described holding section 121 forms as follows: the action force of putting aside towards upper lock position when described holding section 121 is disengaged the unlock operation of described operating portion 122 after door 102 is opened is maintained at lockset position of coupler, at described door 102, again moved to the stage of make position, described action force is disengaged, and described holding section 121 is automatically moved to upper lock position and is fastened on described engaged part 111 thus.

Like this, after 103 pairs of codes of pull-type coded lock, operating portion 122 becomes and is not subject to restrict, next, as long as operating portion 122 is carried out to unlock operation, holding section 121 will be switched to lockset position of coupler from upper lock position, and pull-type coded lock 103 is reset to non-to code state, open door 102 after, as long as make it again move to make position, just can be placed on locking state, therefore, this locking and unlocking device 100A can with few step for.

And, because the operations linkage with operating portion 122 is reset to pull-type coded lock 103 non-to code state, so with, for example, to utilize door 102 to reset for the relative action of casing 101 situation that the mode of pull-type coded lock 103 forms, compare, without the precision with good, pull-type coded lock 103 is assemblied between casing 101 and door 102, makes the locking and unlocking device 100A that effectively realizes action reliably by simple easy assembling become possibility.

And then, even if remove the operating physical force to operating portion 122 after opening door 102, holding section 121 is also still maintained at lockset position of coupler, in the stage holding section 121 that has moved to make position, move to upper lock position, therefore, even if 121Huo engaged part, holding section 111 is the so-called horizontal sickle shaped members as present embodiment, also without improving, precision can be avoided the action of holding section 121 and the closed action of door 102 interferes, and realizes appropriate and reliable closure state and locking states.

In addition, owing to being provided with for detection of door 102 checkout gear 7 whether in the close position between casing 101 and door 102, so can make again holding section 121 actions after whether detecting gate 102 arrives make position reliably, interfere thereby can positively avoid with the switch motion of door 102.

Have again, also be provided with the 1st rotary body 23 and the 1st rotary body 23 is constrained in to the confining part 6 that action force is put aside position, wherein, the 1st rotary body 23 as action force savings member savings make holding section 121 from lockset position of coupler the action force towards upper lock position, the savings of this action force is 121 operations due to operating portion 122 and moving from upper lock position to lockset position of coupler in holding section, after this, before being disengaged after door 102 is opened and to the operating physical force of operating portion 122, carry out.Described checkout gear 7 is detecting the confining force of removing described confining part 6 when door 102 has moved to the situation of make position again, makes from lockset position of coupler, to move to upper lock position under the effect of the action force that holding section 121 puts aside at the 1st rotary body 23.Owing to having adopted such formation, thus the detection that can make the make position of being undertaken by checkout gear 7 with the releasing of the action force of holding section 121 is linked rightly.

Have again, owing to checkout gear 7 being comprised be located at the displacement portion 72 of door 102 sides, this displacement portion 72 is contacted and is carried out displacement by the thrust piece 71 with being located at casing 101 sides, thereby make confining part 6 from constrained, move to unconfinement position with respect to the 1st rotary body 23, particularly due to make this displacement portion 72 contact in the limit of the rotating side of door 102 102b of side with this thrust piece 71, separated, so can embed compactly and obtain exactly mechanical displacement.

In addition, due to the associated 100C of portion in the described associated 100C of portion, 100D has been configured to ratchet structure, utilize the unlock operation of operating portion 122 pull-type coded lock 103 to be reset to non-to after code state, in the situation that this unlock operation is disengaged, allow operating portion 122 upwards lock side to recovery action, INHIBITORY-gate is closed the unlock operation once again of this later operating portion 122, thus can effectively prevent pull-type coded lock 103 be reset to non-to operating portion after code state 122 upwards lock side to recovery action hindered.

And then along locking the flexible power of directive effect, due to the operating physical force disappearance of unlock operation, this operating portion 122 makes progress lock side to action on operating portion 122.Owing to having adopted such formation, so as long as handle unclamps from operating portion 122, just can make operating portion 122 automatically make progress lock side to recovery.

Especially, because operating portion 122 doubles as the handle of shutter door 102 use, so can carry out swimmingly unlock operation and opening operation thereafter by a series of action.

As concrete form, pull-type coded lock 103 has bar 131 and action body 104.Wherein, bar 131 is loaded to a direction elasticity, when 130 pairs of codes of pull-type coded lock main body, overcome resilient movement to and be maintained at assigned position, and at non-this confining force of removing during to code; Action body 104 is non-to code state by pull-type coded lock main body 130 being reset to a direction action, by pull-type coded lock main body 130 being placed in and reseting holding state to other direction action.To between described bar 131 and described operating portion 122, by means of the 1st associated 100C of portion, carry out association, in the non-unlock operation of forbidding described operating portion 122 during to code, when to code, allow this unlock operation, and, to between described action body 104 and described operating portion 122, by means of the 2nd associated 100D of portion, carry out association, followed and pull-type coded lock main body 130 is reset to non-to code state to the unlock operation of this operating portion 122 after code.Due to such form, so can make bar 131, action body 104 and operating portion 122 link rightly.

In addition, in the above-described embodiment, because holding section 121 is that sickle shaped stretches out and such relation is received in engaged part 111, so be applied in the application with such snap-in structure, after locker etc., can directly to holding section 121, drive.

Particularly, holding section 121 is the direction extension along with being in the switching direction quadrature of the door 102 in make position, on its top, there is the sickle shaped member of crooked claw 121a, be directed to this, can this claw 121a be fastened on the engaged part 111 of inner surface of casing 101 by above-mentioned snap-in structure and realize closure state.

And, if the locking and unlocking device 100A of present embodiment is applied between door 102 and casing 101, do not require high precision pull-type coded lock 103 can be assemblied in simply door 102 and casing 101 between just can form the furniture for accommodation A such as locker, thus, can make that locking and unlocking device 100A is steady in a long-term, action reliably, making effectively to improve allly becomes possibility if carry out rapidly, simply the ease of use that deposits the accommodation device 100B such as taking-up in of personal belongings etc.

For example, checkout gear adopts the device that utilizes electric detection to carry out to be also fine.In this case, restraint device is effective by drivings such as electromagnetic coils.

In addition,, except door, open and close member can be also drawer etc., can also pull-type coded lock, operating portion and holding section be set in casing side, in open and close member side, engaged part is set.

And then, because be not subject to the impact of the forms such as shape of holding section or engaged part, so, also can be bolt shape with engaged part and stretch out, holding section forms the relation of its receiving.

In addition, holding section also can be configured to along opening and closing direction and stretches out and be fastened on casing.

Have again, follow the unlock operation of operating portion after code is made as pull-type puzzle lock main body weight by the 2nd associated portion non-in the situation of code state, the form being reset while also comprising the unlock operation of having removed operating portion.
