On the other hand, the locking-unlocking device 1 of present embodiment, in the end plates 22a of the drawer 22 shown in Fig. 2 and Fig. 4 etc., between handle 31 and axis of rotation 34, be inserted with clutch 11, make cam 12 be engaged in this clutch 11, and in order to give the change action from lock-out state to released state to this cam 12, near the handle 31 of this drawer 22, be provided with the dialing lock 13 as input part.

Handle 31, as Fig. 5 (a), (b) rotate freely matched in clearance shown in like that in axis of rotation 34, clutch 11 is configured to can rotate integratedly with axis of rotation 34 in the adjacent position of handle 31 and can slide at direction of principal axis, from the axle center displacement of axis of rotation 34 the position related 11a of portion that is arranged at the part of clutch 11 be engaged under the state (state that clutch engages) of Fig. 5 (c) of associated 31a of a part that is arranged at handle 31, the rotation of handle 31 is passed to axis of rotation 34 via clutch 11, and under the state (state of clutch separation) of Fig. 5 (a) that this joint has been disengaged, the rotation of handle 31 is not transmitted but idle running freely to axis of rotation 34.

Cam 12, as Fig. 2 and as shown in Figure 4 for being installed on the tabular component of the backplate 22a1 of end plates 22a around horizontal axis m, top ends 12a such as the Fig. 4 that has made from horizontal axis m displacement and the junction surface 11b that always is engaged in a part that is arranged at clutch 11 as shown in Figure 5.Cam 12 separates clutch 11 shown in Fig. 5 (a) like that in the latched position of facing the Fig. 6 that forms to right rotation, and the unlocked position facing the Fig. 4 that forms to anticlockwise engages clutch 11 shown in Fig. 5 (c) like that.Under the situation of present embodiment, by elastic bodys such as spring 15 to the unlocked position of Fig. 4 to cam 12 elastic stressings.

Dialing lock 13 constitutes: so basic mechanism omits from the major part as general mechanism's internal mechanism, but bar 13b as shown in Figure 4 can be outstanding to a side from shell 13a rotationally, the position that the top of this bar 13b has been connected in from the horizontal axis m displacement of cam 12 via connecting axle n, bar 13b does not rotate downwards and is held in this position when shown in Figure 6 matching, and the confining force of this bar 13b is disengaged when coupling shown in Figure 4.That is, when not the matching of dialing shown in Figure 6 lock 13, opposing elastic body 15 and cam 12 is remained in latched position, thus handle 31 separate with axis of rotation 34, even become the lock-out state that operating handle 31 also only can dally.On the other hand, when the confining force of this bar 13b is disengaged, cam 12 as mentioned above like that by elastic body 15 to the unlocked position elastic stressing, so it becomes trigger, cam 12 moves to unlocked position as Fig. 6 → Fig. 4, by clutch 11 handle 31 is contacted with axis of rotation 34, become the released state that to remove breech lock by handle 31.

And, present embodiment such as Fig. 2 and also dispose working body 4 in the part of drawer 22 with dialing lock 13 as shown in Figure 4, drawer 22 leaves from housing 21 and makes the direction that this working body 4 represents by arrow P to Fig. 2 (from end plates 22a outstanding direction rearward) work when being released after the coupling of dialing lock 13, and the pushing reaction force by drawer 22 during near housing 21 is to another direction of representing by arrow Q (submerge in end plates 22a direction) work, utilizes the work of this working body 4 dial to lock 13 to be reset to the state of not matching.

If specifically describe, working body 4 as Fig. 2, Fig. 7 and as shown in Figure 8, be the member of the cylindrical shape that is constituted by resin etc. near the inside that is disposed at the lateral margin of the backplate 22a1 that constitutes end plates 22a, can be installed on rotatably near the back side of backplate 22a via (center on) vertical L1 via the supporter 41 of T shape.And, shown in Fig. 8 (a) → (b) → (c) → (d), be connected to like that drawer 22 is pushed in housing 21 in the time housing 21 side plate 21 front surface 21x and be pushed in the end plates 22a that submerges opposite push-on force disappearance and rearward giving prominence to when drawer 22 leaves from housing 21 like that as Fig. 8 (d) → (c) → (b) → (a) shown in by its reaction force.The elastic force that action can utilize elastic body 130 described later (with reference to Fig. 9) should be given prominence to, also elastic body can be assembled in addition in position.

And, via link gear 5, make the motion interlock of the release link 13c outstanding from dialing lock 13 to opposite side and this working body 4.Link gear 5 comprises as Fig. 2, Fig. 7 and as shown in Figure 8: the movable support 51 of front surface side that can be installed on the backplate 22a1 of end plates 22a around fulcrum L2 rotatably; Will be from the position of the axle center L2 displacement of this movable support 51 the 1st connecting rod 52 with the rotation interlock of the rotation that makes supporter 41 from being connected between the position of the axle center L1 displacement of the supporter 41 of described T shape and movable support 51; The 2nd connecting rod 53 from outstanding/action interlock of submerging of shell 13a with the spinning movement that makes movable support 51 and release link 13c.

Release link 13c such as Fig. 9 modal representation, constitute: by the elastic bodys such as spring 130 of the inside that is arranged at shell 13a to making it from the shell 13a of dialing lock 13 outstanding direction reinforcing laterally, bring influence can not in the shell 13a that submerges the time dialing status of dialing lock 13 at opposing elastic body 130, afterburning and the dialing of dialing lock 13 made zero when outstanding from shell 13a and reset by elastic body 130.Comprising makes zero resets, and when not the matching of dialing, is held in the turned position, below from the outstanding bar 13b of opposition side, and when coupling, this confining force is disengaged, and these were narrated.

That is, be positioned at the fastening position shown in Fig. 8 (d), working body 4 at drawer 22 and pushed to end plates 22a by the front surface 21x of housing 21 and be positioned at when not having the implantation site, be in the state that pushes release link 13c via link gear 5.If dialing this moment lock 13 is in the state of not matching, then as shown in Figure 6, turned position below confining force acts on the bar 13b, cam 12 is held in the latched position that clutch 11 is made as separation.Next, when making dialing lock 13 couplings, the confining force of bar 13b is disengaged, and it becomes trigger, and cam 12 moves to unlocked position shown in Figure 4, and handle 31 is connected by clutch 11 with axis of rotation 34, and handle 31 becomes the state that can operate.When pulling out with breech lock 33 releasings and with drawer 22 by handle 31, such shown in Fig. 8 (d) → (c) → (b) → (a), it is side-prominent to the back side from the inside of end plates 22a to be positioned at the working body 4 that does not have the implantation site, and the elastic force put aside by elastic body shown in Figure 9 130 of the release link 13c that pushes via link gear 5 is released laterally before this.Thus, dialing lock 13 is made zero and is resetted.Constitute, make zero when resetting at this, bar 13b turns to the turned position, below and is held in this position, and cam 12 moves to latched position as Fig. 4 → resist elastic body 15 as shown in Figure 6 thus, and clutch 11 becomes the state of separation again.Clutch 11 is in the state of separation when pushing drawer 22, and drawer 22 is tied down in reception position so breech lock 33 temporarily submerges simultaneously.At this moment, working body submerges shown in Fig. 8 (a) → (b) → (c) → (d) like that, and release link 13c resists elastic body 130 again and is pushed into, but the reset mode that makes zero is kept in the dialing of dialing this moment lock 13.

As mentioned above, the locking-unlocking device of present embodiment possesses dialing lock 13 and working body 4 in drawer 22 sides that open and close housing 21, working body 4 constitutes, in dialing lock 13 coupling backs make drawer 22 from housing 21 leave and when being released to a direction job and because drawer 22 is pushed near housing 21 and to another direction work, utilize the work of this working body 4 to dial to lock 13 to be reset to the state of not matching.

Like this, after dialing lock 13 couplings, utilize drawer 22 to make working body 4 work with respect to the relative action of housing 21, thus dialing is reset to the state of not matching, so except the operation that opens and closes drawer 22, do not need to carry out the other operation be used to resetting, can action of operation minimizing.And, working body 4 is between housing 21 and drawer 22, pushed by the other side's member or discharge and work, lock 13 and working body 4 are disposed at drawer 22 sides jointly as long as will dial, so can utilize the on-off action of drawer 22, also avoid spreading all over the structure that disposes such complicated such as connecting rod between the two and become the obstacle of accommodation space simultaneously effectively.

At this moment, working body 4 is at elastic body 130 savings screen resiliences being pushed into when another direction is worked, and utilize this screen resilience to the member of a direction job, so can be only by acting on the elastic force of elastic bodys 130 grades at working body 4 and easily realizing to the motion of a direction and another direction.

Particularly, working body 4 is configured to, by being pushed into the boundary member of the drawer that submerges when closing 22 and housing 21, outstanding from this boundary member by being released, can so directly utilize the front surface 21x as the other side's that working body 4 is pushed housing 21, as long as only at drawer 22 side assembly working bodies 4, also become easy so make.

If from a security point of view, dialing lock 13 constitutes, the work of the working body 4 when utilizing drawer 22 to leave from housing 21 and be reset to the state of not matching, so be reset in the 22 o'clock number of matches that begin to pull the drawer out, can effectively avoid under the state that drawer 22 is being opened number of matches by around the people see.

In addition, if the viewpoint from operability, dialing lock 13 constitutes by coupling the lock-out state of drawer 22 is automatically terminated, dialing lock 13 is as the dialing latch mechanism and pass through coupling immediately with latch-release, so do not need to rotate at least the so other unlocking operation of knob, can reduce by an action here yet.

Perhaps, utilize the work of working body 4, only just can make its state that is transformed into locking automatically by making drawer 22 next move to fastening position, so can and not carry out the unnecessary lock-out state that operatively successfully is converted to next time as the dialing latch mechanism.

And then, having the bolt lock mechanism 3 that comprises handle 31 in drawer 22 sides, dialing lock 13 and working body 4 also are arranged on drawer 22 sides, so can become the configuration of the operation of the operation of the lock 13 that dials and handle 31 a succession ofly, operability are significantly promoted.

As bolt lock mechanism 3, for the operating physical force that is input into handle 31 being passed to the mechanism that breech lock is removed this breech lock via the transmission system A that comprises axis of rotation, position in the switching that the part of this transmission system A is cut off/connected is provided with clutch 11, this clutch 11 is not made as separation when the matching of dialing lock 13, the mode that when the coupling of dialing lock 13 this clutch 11 is made as joint makes dialing lock 13 be associated with clutch 11, so can utilize the part of existing bolt lock mechanism 3 realize effectively by the coupling of dialing lock 13 lock-out state of drawer 22 is removed or by dialing lock 13 to the state of not matching reset with drawer 22 be made as can lock-out state effect, also can carry out switching between lock-out state and the latch-release state by extremely slight action.And, even operating handle 31 also only is idle running when locking, so operating physical force can be to the breech lock transmission, so can avoid effectively owing to applying the state of affairs that irrational operation makes the breech lock breakage.

And, open and close member is drawer 22, the inside at the end plates 22a of this drawer 22 arranges working body 4, the front surface of housing 21 utilizes with keeping intact, so the position that working body 4 is set not only as shown example be near the inside the lateral margin of end plates 22a like that, also can be set in the inside of upper limb side, the inside of lower edge side, can become the higher structure of design freedom.

In addition, the concrete structure of each one not merely is defined in above-mentioned embodiment, can carry out various changes in the scope that does not break away from aim of the present invention.

For example, be provided with dialing lock 13 and working body 4 in drawer 22 sides as open and close member in the above-described embodiment, but also can be the mode that these dialing locks 13 and working body 4 are set in housing 21 sides.

In addition, make working body 4 work, thus dialing portion be reset to the state of not matching even constitute the coupling, the action (action when namely closing) near drawer 22 after pulling out that utilize dialing lock 13, also can play basic action effect of the present invention.

In addition, open and close member is not limited to drawer, is under the situation of door 122 at Figure 10, as shown in Figure 11 open and close member for example, also can use the present invention effectively.The member of Figure 10 constitutes, and in edge part or near the inside the edge part of the rotating shaft side of door 122 working body 4 is set, and the front surface 121x of the housing 121 by being positioned at its position, opposite pushes working body 4.Certainly, also can constitute and working body 4 is arranged at housing 121 sides and pushes by door 122.In addition, the member of Figure 11 constitutes, and in edge part or near the inside the edge part of the opposite side with the rotating shaft side of door 122 working body 4 is set, and the front surface 121x of the housing 121 by being positioned at its position, opposite pushes working body 4.Certainly, also can constitute and working body 4 is arranged at housing 121 sides and pushes by door 122 this moment.In addition, the transmission system that dialing lock and the lock that will dial are connected with working body 4 in these accompanying drawings has been omitted diagram, but certain much less it constitutes the work that utilizes working body 4 and can lock the state of not matching that be reset to dialling.

(the 2nd embodiment)

Figure 12～Figure 14 represents the 2nd embodiment of the present invention.In these figure, give same-sign for drawer 22, bolt lock mechanism 3, transmission system A, handle 31, locking-unlocking device 1, dialing lock 13 etc. with the essentially identical part of above-mentioned the 1st embodiment, for the part that does not need to specify relative explanation is omitted.

Yet, in the present embodiment, local configuration at drawer 22 has dialing lock 13 and working body 104, drawer 22 leaves from housing 21 and a direction (leaving and the mobile direction of rearward sliding from end plates 22a) work that this working body 104 is represented by arrow R to Figure 12 after the coupling of dialing lock 13, and the reaction force that pushes by drawer 22 during near housing 21 makes this working body 104 to the other direction of representing by arrow S (near the direction in the end plates 22a) work, utilizes the work of this working body 104 dial to lock 13 to be reset to the state of not matching.

If specifically describe, working body 104 is the members of resin etc. that comprise the pilot hole (not shown) etc. of the side that is configured to be engaged in slidingly back and forth the side plate 22b that is arranged at drawer 2, has the joint fastener 104a of the front surface 21x of the side plate 21a that is engaged in housing 21 when drawer 22 is pushed to housing 21 from the place ahead.When drawer 22 was more forwards pulled out than the state of Figure 13 (a), joint fastener 104a became the state that forwards separates from the front surface 21x of the side plate 21 of housing 21.And, when shown in Figure 13 (a) → (b) → Figure 14 (a) → (b), being pushed in drawer 22 in the housing 21 from this state like that, joint fastener 104a is connected to the front surface 21x of the side plate 21 of housing 21, by its reaction force, working body 104 relatively moves at side plate 22b to the direction near end plates 22a, on the contrary when drawer 22 leaves from housing 21 like that shown in Figure 14 (b) → (a) → Figure 13 (b) → (a), push-on force disappears, working body 104 to from end plates 22a away from direction relatively move at side plate 22b.And when drawer 22 was further opened from the state of Figure 13 (a), working body 104 became fully the state that forwards separates from the front surface 21x of the side plate 21 of housing 2 again.The elastic force that action can utilize elastic body shown in Figure 9 130 should be given prominence to, also elastic body can be assembled in addition in position.
