Description

Locking / unlocking device and storage furniture using the same

In the present invention, the engaging portion and the engaged portion are engaged to hold the opening / closing member such as the drawer and the door in the closed position, and the engagement portion is appropriately associated with the dial lock and the operation portion by simple incorporation. The present invention relates to a locking / unlocking device that can appropriately perform locking / unlocking of an opening / closing member through a simple operation and storage furniture to which the locking / unlocking device is applied.

This type of locking / unlocking device using a dial lock is attached to a door or the like having an engaging portion such as a latch, and the operation of the operation portion is prohibited by disabling the dial lock. In general, the mating portion is constrained so that it cannot be operated, and when opening the door or the like, the dial lock is collated so that the operation portion can be operated.

Also, it is desirable to reset the dial lock to the non-verified state again when the door is opened after verification.

It has been.

Japanese Patent Publication No. 6-60544

By the way, in the old one, when opening the door, etc., it is necessary to perform a two-step operation, that is, an operation for collating the dial and an operation for turning the knob. Moreover, if an operation for resetting the dial is added after the door is opened, the number of procedures is further increased. If the old idea is appropriately combined with the idea of resetting the dial to zero as in Patent Document 1, the simplification of the procedure can be expected. However, after turning the knob and resetting to zero, an operation to return the knob, an operation to open a door by operating a different handle, a knob operation to close the door, etc. was added. It becomes complicated.

On the other hand, the operation lock attached to the dial lock can be assembled between the door and the housing so that the dial lock is reset by using the relative movement of the door to the housing. However, when adopting such a configuration, accuracy is required when assembling the dial lock between the door and the housing, and a relatively high degree of assembly is required. In addition, it is necessary to consider separately for stable and reliable operation.

On the other hand, in order to eliminate the need for a knob operation when closing the door, the door-side engaging portion is automatically engaged with the case-side engaged portion together with the door closing operation without any operation to the operation portion. However, when the engaging part is of a side-facing sickle lock type, for example, the door opening / closing operation interferes with the operation of the engaging part. I need it.

The present invention has been made paying attention to such a problem. The dial lock can be easily assembled between the housing and the opening / closing member to be surely operated, and the opening / closing member such as a door can be applied. It is an object of the present invention to provide a locking / unlocking device and a storage furniture to which the locking / unlocking device is configured so that the lock can be performed as few as possible as a whole.

In the present invention, in order to achieve such an object, the following measures are taken.

That is, the locking and unlocking device of the present invention includes a housing and an opening / closing member that opens and closes the opening of the housing, a dial lock, an operation unit, and an engagement unit provided in either the housing or the opening / closing member, An engagement portion provided on either the casing or the opening / closing member, and the engagement member and the engagement portion are engaged to hold the opening / closing member in the closed position. The operation unit receives an unlocking operation and switches the position of the engaging part with respect to the engaged part from a locked position to an unlocked position. The unlocking operation is prohibited and the unlocking operation is allowed at the time of collation, and at least the operation unit through the related unit is reset to the non-collation state in conjunction with the subsequent unlocking operation. The engaging part automatically moves to the locked position after the unlocking operation to the operating part is released and before the opening / closing member moves to the closed position again. It is comprised so that it may engage with an engaging part.

In such a configuration, when the opening / closing member is in the closed position and the dial lock is not collated, the unlocking operation of the operation portion is prohibited by the dial lock, and the engaging portion does not move to the unlocking position. Next, when the dial lock is verified, the prohibition state for the operation unit is released and the unlocking operation is allowed. When the operation part is unlocked, the engaging part moves from the locking position to the unlocking position, and the opening / closing member can be opened. In addition, the dial lock is reset to the non-verification state with the unlocking operation. If the opening / closing member is opened and then moved to the closing position again, the engaging portion can be engaged with the engaged portion by itself. At this time, the dial lock is in a non-collation state, and the unlocking operation of the operation unit is prohibited. Therefore, the operation unit cannot be operated again unless the dial lock is collated.

In this way, the operation part becomes free after collation of the dial lock, and then the engagement part is switched from the locked position to the unlocked position only by unlocking the operation part, and the dial lock is reset to the non-collated state, Further, since the locked state can be achieved simply by moving the opening / closing member to the closed position, the locking / unlocking device can be used in as few steps as possible.

Moreover, since the dial lock is reset to the non-collation state in conjunction with the operation of the operation unit, for example, the dial lock is reset as compared with the case where the dial lock is reset using the relative movement of the opening / closing member with respect to the housing. Is not required to be accurately integrated between the casing and the opening / closing member, and a locking / unlocking device that operates reliably with simple assembly can be effectively realized.

In order to prevent the operation unit from being prevented from returning to the locking direction after the dial lock has been reset to the non-collation state, the related unit can be brought into the non-collation state by the unlocking operation of the operation unit. It is desirable to have a ratchet structure that permits a return operation in the locking direction of the operation unit and prohibits the unlocking operation of the operation unit again when the unlocking operation is released after the reset.

In order to simplify the procedure after the unlocking operation of the operation unit, the operation unit is operated in the locking direction by applying an elastic force to the operation unit in the locking direction and the operation force related to the unlocking operation disappearing. It is desirable to make it so.

In order to smoothly link the unlocking operation and the subsequent opening operation, it is preferable that the operation unit also serves as a handle for opening and closing the opening / closing member.

As a specific embodiment, the dial lock is elastically biased in one direction and is moved and held in a predetermined position against the elasticity when the dial lock body is collated, and the holding force is released when it is not collated. A lever and an actuating body that operates in one direction to reset the dial lock body to a non-verification state and operates in the other direction to place the dial lock body in a reset standby state, between the lever and the operation unit. Are associated with each other via the first related part, and the unlocking operation of the operation unit is prohibited at the time of non-collation, the unlocking operation is allowed at the time of collation, and the second related part is provided between the operating body and the operation part. The dial lock body is reset to the non-collation state in association with the unlocking operation of the operation unit after collation.

As a structure to be applied to storage furniture such as a locker, it is preferable that either the engaging portion or the engaged portion has a relationship in which either one protrudes in a sickle shape and the other receives this.

In this case, in order to appropriately avoid the interference between the engaging portion and the engaged portion when closing the opening and closing member, and the engagement portion is engaged, the unlocking operation of the operation portion is performed after the dial lock is verified. Releases elastically to the locked position when released, and engages after the interference avoiding operation is temporarily performed against the elastic force by hitting the engaged part immediately before the opening / closing member reaches the closed position. It is preferable to configure so as to engage with the part.

In order to smoothen the operation at that time, it is desirable that the engaging portion is configured to perform an interference avoiding operation without dragging the operating portion.

Such a configuration is particularly suitable for one in which either the engaging portion or the engaged portion extends along the opening / closing direction of the opening / closing member in the closed position and has a claw portion bent at the tip. Applicable.

And, if the locking and unlocking device of this embodiment is applied between the opening and closing member and the housing, it can be easily and reliably assembled for a long period of time without requiring accuracy, and can be operated stably over a long period of time. Usability of the storage device to which this is applied can be effectively improved.

In addition, the present invention takes the following other means in order to achieve this object.

That is, the locking / unlocking device of the present invention includes a housing, an opening / closing member that opens and closes the opening of the housing, a dial lock, an operation unit, and an engagement unit that are provided on either the housing or the opening / closing member. An engaged portion provided on the other of the casing and the opening / closing member, and holding the opening / closing member in the closed position by engaging the engaging portion and the engaged portion. The operation portion receives an unlocking operation and switches the position of the engaging portion with respect to the engaged portion from the locked position to the unlocked position, and the dial lock is at least when the opening / closing member is closed. In this case, the unlocking operation of the operation unit is prohibited at the time of non-verification, the unlocking operation is permitted at the time of verification, and is reset to the non-verification state in conjunction with the subsequent unlocking operation. Are those associated with at least the operating section through part. Then, when the unlocking operation to the operation unit is released after the opening / closing member is released, the engaging portion is held at the unlocking position while accumulating the operating force toward the locking position, and the opening / closing member is closed again. When the operating force is released at the stage of moving to the position, the moving force is automatically moved to the locked position and engaged with the engaged portion.

In such a configuration, when the opening / closing member is in the closed position and the dial lock is not collated, the unlocking operation of the operation portion is prohibited by the dial lock, and the engaging portion does not move to the unlocking position. Next, when the dial lock is verified, the prohibition state for the operation unit is released and the unlocking operation is allowed. When the operation part is unlocked, the engaging part moves from the locking position to the unlocking position, and the opening / closing member can be opened. In addition, the dial lock is reset to the non-verification state with the unlocking operation. After the unlocking, even if the unlocking operation on the operation unit is released, the engaging unit is held at the unlocked position while accumulating the operating force toward the locked position. Then, when the opening / closing member is moved again to the closing position, the engaging portion automatically engages with the engaged portion by releasing the accumulated operating force. At this time, the dial lock is in a non-collation state, and the unlocking operation of the operation unit is prohibited. Therefore, the operation unit cannot be operated again unless the dial lock is collated.

In this way, the operation part becomes free after collation of the dial lock, and then the engagement part is switched from the locked position to the unlocked position only by unlocking the operation part, and the dial lock is reset to the non-collated state, After the opening / closing member has been opened, it can be brought into the locked state simply by moving it to the closed position again, so that this locking / unlocking device can be used with as few procedures as possible.

Furthermore, even if the operating force on the operating part is released after opening the opening and closing member, the engaging part remains held in the unlocked position, and the engaging part moves to the locked position when moved to the closed position. Regardless of the form of the engaging part or the engaged part, even if the engaging part or the engaged part is in the form of a sickle or a hook, the engaging part and the opening / closing member Therefore, proper and reliable operation can be ensured.

In this case, prohibiting the unlocking operation of the operation unit at the time of non-verification includes a structure in which the position of the engaging portion is not switched even if the operation unit is operated at the time of non-verification.

In order to reliably detect whether or not the opening / closing member has reached the closing position, a detecting means for detecting whether the opening / closing member is in the closing position is provided between the housing and the opening / closing member. desirable.

In order to appropriately link the detection of the closing position by the detecting means and the release of the operating force to the engaging portion, the engaging portion is moved from the locked position to the unlocked position by the operation of the operating portion, and then the opening / closing member is moved. An operating force storage member that stores an operating force that moves the engaging portion from the unlocked position to the locked position until the operating force is released and the operating force is released, and the operating force storage member stores the operating force. A restraining member that restrains the position, and when the detecting means detects that the opening and closing member has moved to the closed position again, the holding force by the restraining member is released, and the accumulated operation force accumulating member is stored. It is preferable that the engaging portion is moved from the unlocked position to the locked position by power.

A specific embodiment of the detection means includes a displacement portion provided in either the housing or the opening / closing member, and the displacement portion is displaced by being in contact with either the housing or the opening / closing member. In this case, the restraining member is moved from the restraining position to the non-restraining position with respect to the operating force accumulating member.

In order to prevent the operation unit from being prevented from returning to the locking direction after the dial lock has been reset to the non-collation state, the related unit can be brought into the non-collation state by the unlocking operation of the operation unit. A ratchet structure that allows the operation part to return to the locking direction when the unlocking operation is released after resetting and prohibits the unlocking operation of the operating part after the door is closed again. It is desirable that

As the structure to be applied to storage furniture such as a locker, it is preferable that either the engaging portion or the engaged portion has a relationship in which either one protrudes in a sickle shape or a bowl shape and the other receives this. .

Such a configuration can be suitably applied particularly to one in which either the engaging portion or the engaged portion extends along a direction orthogonal to the opening / closing direction of the opening / closing member in the closed position. .

Since the present invention has the configuration described above, in the case where the opening / closing member is locked / unlocked with respect to the housing by the engaging portion and the engaged portion, the opening / closing member is simply operated by collating the dial lock. Can be reset and the collation state of the dial lock can be reset, and can be held in the locked position at the closed position simply by pushing the opening / closing member. For this reason, it can be used with as few operating procedures as possible, and storage furniture such as lockers can be configured by simply assembling a dial lock without requiring high precision between the opening and closing member and the housing. This makes it possible to effectively improve the usability of the storage device, for example, by allowing the locking / unlocking device to operate stably and reliably over a long period of time, enabling quick and easy access to personal items and the like.

(First embodiment)

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

1 to 3 show a storage device B to which the locking / unlocking device A of the present embodiment is applied. In this storage device B, a door 2 as an opening / closing member is disposed at a position for opening and closing a storage space of the housing 1, and a locking / unlocking device A is applied between the door 2 and the housing 1. This locking / unlocking device A incorporates the engaging portion 21 and the dial lock 3 into the door 2, provides the engaged portion 11 on the housing 1 side, and simply pushes the door 2 to make the engaged portion 21 into the engaged portion. 11, the door 2 is locked in the closed position relative to the housing 1 by being locked, and the engagement portion 21 and the engagement portion 11 are confirmed by collating the dial lock 3 provided on the door 2. The door 2 can be opened by releasing the engagement with the dial 2 and the collating state of the dial lock 3 is reset using the operation of turning the knob 22a, which is the first opening operation of the door 2 thereafter.

More specifically, the door 2 is supported by the side plate 12 of the housing 1 through the hinge mechanism H so as to be able to open and close the edge portion 2a on the suspension side, and the side plate 12 positioned on the opposite side of the hinge H. A step 12a that is concave toward the front is formed on the front surface of the door 2, and when the door 2 is closed, the thickness of the edge 2b on the anti-hanging side of the door 2 in the step 12a that becomes the recess. The part fits. On the front surface of the door 2, an operation unit 22 configured to perform an unlocking operation is provided. This operation part 22 has a knob part 22a that can be operated by picking with fingers, and also has a function of a handle that can be opened by opening the door 2 while being picked. By rotating approximately 90 degrees counterclockwise (unlocking direction), the engagement between the engaging portion 21 and the engaged portion 11 is released, and when the finger is released, it is elastically rotated clockwise (locking direction). is there.

The engaging portion 21 is a sickle-like member that is provided so as to be movable up and down in a state of protruding rearward from the back surface in the vicinity of the edge 2b on the side opposite to the suspending side of the door 2, It is a slit-like thing provided in the corresponding position of the engaging part 21 in the contact surface 12x located in the inner back of the said step part 12a formed in the housing | casing 1. FIG. The sickle-like engaging portion 21 is a substantially L-shaped plate made of steel or the like, and has a claw portion 21a whose tip is bent downward.

Then, a movable member 23 is arranged on the back surface of the door 2 so as to be movable up and down as shown in FIGS. 3 and 6, and the engaging portion 21 is integrally formed on a part of the movable member 23. A cam portion 22 b provided on the back surface of the operation portion 22 is associated with the movable member 23. That is, the cam portion 22b is disposed at a position that supports the lower surface 23a of the movable member 23. In the state of the solid line in FIG. 6A in which the operation portion 22 rotates in the locking direction, the movable member 23 is lifted. The engaging portion 21 is held in the lowered locking position. However, when the operation portion 22 is operated in the unlocking direction indicated by the arrow in the figure, the lower surface 23a of the movable member 23 is lifted by the cam portion 22b, and the engaging portion 21 is engaged. The mating portion 21 is moved up to the unlocking position.

As shown in FIG. 3 and the like, the dial lock 3 has the lever 31 and the operating body 4 projecting from the box-shaped dial lock body 30 toward the back surface of the operation unit 22.

More specifically, the lever 31 is urged by a spring 32 in a downward direction where a portion displaced from the fulcrum n is one direction, and the dial lock 3 is a schematic illustration of the lever 31 shown in FIG. It has a function of holding it in a horizontal upward rotation position and releasing the holding force when it is not verified. The lever 31 released from the holding force moves to the downward rotation position shown in FIG.

The actuating body 4 has a base end biased in a protruding direction by a spring 30a inside the dial lock body 30, and is immersed in the casing 30 while accumulating elastic force when the distal end is pushed in one direction. When the pushing force is released, it projects in the other direction.

The dial lock body 30 does not affect the dial state of the dial lock 3 when the operating body 4 protrudes from the casing 30, and should reset the dial of the dial lock 3 to zero when immersed in the casing 30. It is configured. That is, when the dial is collated, the lever 31 is rotated from the state of FIG. 3 to the horizontal upward rotation position of FIG. 4 and held in that position, and the operating body 4 is moved from the state of FIG. 4 to the position of FIG. When pushed, the dial is reset to zero and the holding force of the lever 31 is released, and the lever 31 tends to move from the state shown in FIG. 5 to the downward rotation position shown in FIG. Since various things are already known about the reset structure etc. of the dial lock 3, description of an internal structure is abbreviate | omitted.

Then, the lever 31 and the operation unit 22 are associated with each other via the first related unit C, and the operation state of the operation unit 22 and the operation prohibited state are switched according to the dial collation state. The first related part is located at the turning end of the lever 31 and moves up and down in conjunction with the up-and-down turning operation of the lever 31 and the rotation of the operation part 22 in the locking direction. The moving body 52 is configured to move in a direction approaching the block body 51 (a direction approaching the dial lock body 30). When the moving body 52 is about to move in accordance with the unlocking operation of the operation unit 22 in the state of FIG. 3 where the block body 51 is in the lowered position at the time of non-collation, this is blocked by the side wall 51a of the block body 51, In some cases, the block body 51 is allowed to move when the moving body 52 is about to move in accordance with the unlocking operation of the operation unit 2 in a state where the block body 51 is moved to the raised position as the lever 31 rotates as indicated by an arrow in FIG. Are related to each other. As a result, the moving body 52 can move to a position where it is under the lower surface 51b of the block body 51 as shown in FIG.

Further, the operating body 4 and the operation unit 22 are associated with each other via the second related unit D, and the dial lock body 30 is reset to zero according to the operation state of the operation unit 22. The second related part D attaches the moving body 52 that moves in the direction approaching the dial lock body 30 in accordance with the rotation operation of the operation part 22 to the upright surface 4 a formed at the protruding end of the operating body 4. Consists of. Then, in association with the unlocking operation of the operation unit 22 in the direction indicated by the arrow in FIG.

3 and 6B and the like, a shaft 22c protrudes at a position displaced from the center of rotation on the back surface of the operation unit 22, and the shaft 22c extends in the vertical direction provided on the movable body 52. The shaft 22c and the long hole 52c are inserted into the long hole 52c, and the rotation operation of the operation unit 22 and the advancing / retreating operation of the moving body 52 are interlocked with each other.

Also, a spring 24 a is provided between the movable member 23 and the fixed member 24 in the vicinity thereof so as to give the movable member 23 elasticity in the descending direction. The spring 24a plays a role of pushing down the engaging portion 21 downward (locking direction). Further, the spring 30a acting on the operating body 4 causes an elastic force to act on the operation portion 22 in a locking direction that is opposite to the arrow as shown in FIG. When the operation force in the unlocking direction that has been input to disappears, the operation unit 22 operates in the locking direction. When the operation portion 22 moves in the locking direction, the movable member 23 is lowered by the spring 24a in the direction opposite to the arrow shown in FIG. 6A, and the engaging portion 21 returns to the locking position. When an upward external force is applied from the side of the engaging portion 21 when the door is closed, which will be described later, the movable member 23 can perform an upward movement operation while compressing the spring 24a without dragging the operation portion 22.

As described above, the moving body 52 constituting the first related part C enters the state below the block body 51 in the state shown in FIG. 5 after the unlocking operation. When the dial is reset to the non-collation state by the unlocking operation of the operation unit 22, the lever 31 is rotated downward and the block body 51 is biased in the downward direction, so that the operation of the operation unit 22 is released. At the same time, the moving body 52 interferes with the movement of the moving body 52 to return to the original position together with the protruding operation of the operating body 4 by the spring 30a. Therefore, a curved guide surface 52d is provided at a portion of the moving body 52 that contacts the block body 51, and the moving body 52 passes under the guide body 52d while lifting the block body 51 along the guide surface 52d. It is possible to return to the part corresponding to the protruding position. Accordingly, the lever 31 and the block body 51 are offset to the lowered position shown in FIG. After this, since the unlocking operation of the operation unit 22 is prohibited unless the dial is collated again, the first related unit C has a ratchet structure.

Next, the operation of this embodiment will be described.

First, when the door 2 is in the closed position shown in FIG. 7A and the dial lock 3 is in the non-collation state, the holding force of the lever 31 is released, and the lever 31 is urged by the spring 32 to rotate downward. In position. At this time, the operation of the operation part 22 is prohibited by the first related part C, and the engaging part 21 is in the locked position where the engaging part 21 is engaged with the engaged part 11. Next, when the dial lock 3 is collated, the lever 31 is moved to the upward rotation position by the function of the dial lock 3 as indicated by the arrow in FIG. The prohibition state by C is released. For this reason, as shown in FIG. 8A, by operating the knob 22a of the operation unit 22, the engaging portion 21 is lifted to the unlocking position where the engaging portion 11 is released from the engaged portion 11, and the second portion The actuating member 4 is pushed in by the related part D to reset the dial to zero. If the door 2 is opened in this state, the storage space of the housing 1 is opened as shown in FIG. At the time of such zero reset, the holding force of the lever 31 is released, and the lever 31 tries to rotate toward the downward rotation position by the spring 32. When the operation on the operation unit 22 is released, the operation unit 22 rotates elastically in the locking direction, and the engaging unit 21 is lowered to the locking position shown in FIG. The state of the dial lock 3 at this time is the reset standby state in which the first related part C is again in the operation prohibited state and the operating body 4 protrudes and then immerses in the same manner as in FIG. Move on.

As shown in FIG. 9, when the door 2 is closed, the engaging portion 21 is in the locked position, so when it goes to the closing position as it is, it interferes with the opening edge of the engaged portion 11, but the engaging portion 21 is operated. Even if the portion 22 is not operable, the spring 24a can be compressed and moved upward via the movable member 23 to drag the operation portion 22 (see FIG. 6A). In order to avoid interference with the engaged portion 11, the spring 32 rides on the opening edge of the engaged portion 11 as indicated by an arrow in FIG. Then, it returns to the locking position of FIG. At this time, the claw portion 21a of the engaging portion 21 is engaged with the back surface around the opening of the engaged portion 11, and the dial lock 3 maintains the zero reset state.

As described above, the locking and unlocking apparatus according to the present embodiment includes the housing 1 and the door 2 that is an opening and closing member that opens and closes the opening 11 of the housing 1, the dial lock 3 provided on the door 2, the operation unit 22, and the engagement. An engagement portion 21 and an engaged portion 11 provided in the housing 1 are provided, and the door 2 is held in a closed position by engaging the engaged portion 21 and the engaged portion 11. is there.

The operation unit 22 is configured to accept an unlocking operation so that the position of the engaging part 21 with respect to the engaged part 11 can be switched from a locked position to an unlocked position. The unlocking operation of the operation unit 22 is prohibited during collation, the unlocking operation is permitted during collation, and at least the relevant operation is performed through the related units C and D so that the unlocking operation is reset in conjunction with the subsequent unlocking operation. In association with the part 22, the engaging part 21 is automatically moved to the locking position after the unlocking operation to the operation part 22 is released and before the door 2 moves to the closed position again. It is configured to engage with the engaged portion 11.

As described above, after the dial lock 3 is verified, the operation unit 22 becomes free, and then the engagement unit 21 is switched from the locked position to the unlocked position only by unlocking the operation unit 22, and the dial lock 3 is not verified. Since the locked state can be obtained simply by resetting the state and further moving the door 2 to the closed position, the locking / unlocking device A can be used in as few steps as possible.

Moreover, since the dial lock 3 is reset to the non-collation state in conjunction with the operation of the operation unit 22, for example, compared with a case where the dial lock 3 is reset using the relative movement of the door 2 with respect to the housing 1. Thus, it is not necessary to incorporate the dial lock 3 between the housing 1 and the door 2 with high accuracy, and it is possible to effectively realize the locking / unlocking device A that operates reliably with simple assembly.

Further, when the unlocking operation is released after the dial lock 3 is reset to the non-collation state by the unlocking operation of the operation unit 22, the related unit C of the related units C and D is released. Since the ratchet structure which permits the return operation in the locking direction and prohibits the unlocking operation of the operation unit 22 again, the operation unit 22 returns to the locking direction after the dial lock 3 is reset to the non-collation state. It is possible to effectively prevent the operation from being hindered.

Further, the operation unit 22 is configured to be elastic in the locking direction and operate in the locking direction when the operation force related to the unlocking operation disappears. The operation unit 22 can be automatically returned to the locking direction only by releasing.

Particularly, since the operation unit 22 also serves as a handle for opening and closing the door 2, the unlocking operation and the subsequent opening operation can be smoothly performed by a series of operations.

As a specific aspect, the dial lock 3 is a lever that is elastically biased in one direction and is moved and held to a predetermined position against the elasticity when the dial lock body 30 is collated, and releases the holding force when it is not collated. 31 and an actuating body 4 that resets the dial lock body 30 to a non-verification state by operating in one direction and puts the dial lock body 30 in a reset standby state by operating in the other direction. The operation units 22 are associated with each other via the first related unit C, and the unlocking operation of the operation unit 22 is prohibited at the time of non-collation, and the unlocking operation is permitted at the time of collation. The dial lock body 30 is reset to the non-collation state in accordance with the unlocking operation of the operation unit 22 after collation by associating with each other via the second relational part D. The body 4 and the operation portion 22 can be properly interlocked.

Moreover, in the said embodiment, since the engaging part 21 protrudes in a sickle shape and the to-be-engaged part 11 is in the relationship which receives this, it applies to the application object which has such an engaging structure, for example, a locker, The engaging portion 21 can be driven directly.

In this case, when the door 2 is closed, the engaging portion 21 and the engaged portion 11 interfere with each other, but the engaging portion 21 is unlocked by releasing the unlocking operation of the operation portion 22 after the dial lock 3 is collated. So that the door 2 comes into contact with the engaged portion 11 immediately before reaching the closed position so that the interference avoiding operation is temporarily performed against the elastic force and then the engaged portion 11 is engaged. Therefore, it is possible to effectively realize a configuration that is automatically locked by simply closing the door 2, simplifying the operation procedure, and effectively using it.

And since the engaging part 21 is comprised so that interference avoiding operation | movement can be performed without dragging the operation part 22, closing operation can be performed lightly.

In particular, the engaging portion 21 extends along the opening and closing direction of the door 2 in the closed position, and has the claw portion 21a bent at the tip, and the claw portion 21a is located on the inner back side. A closed state can be realized by reliably engaging the engaged portion 11a through the above-described engaging structure.

And if the locking / unlocking device A of this embodiment is applied between the door 2 and the housing 1, the dial lock 3 can be easily assembled between the door 2 and the housing 1 without requiring high accuracy. The storage furniture A such as a locker can be configured, thereby enabling the locking / unlocking device A to operate stably and reliably over a long period of time, enabling quick and easy access to personal items, etc. Usability of the storage device B can be effectively improved.

Note that the specific configuration of each unit is not limited to the above-described embodiment.

For example, the opening / closing member may be a drawer or the like in addition to the door, or may be provided with a dial lock, an operation unit, and an engaging portion on the housing side, and an engaged portion on the opening / closing member side.

Also, it can be configured so that the engaged portion protrudes in a sickle shape and the engaged portion has a relationship for receiving it.

Furthermore, the engaging part can be configured to protrude in the lateral direction perpendicular to the opening / closing direction and engage with the housing. In this case, when the engaging portion is sickle-shaped, a hook-shaped member having no claw at the tip can be used.

Furthermore, in order to reset the dial lock body to the non-collation state in accordance with the unlocking operation of the operation unit after collation through the second related unit, the mode is reset when the unlocking operation of the operation unit is released Is also included.

Other configurations can be variously modified without departing from the spirit of the present invention.

As shown in FIGS. 16 and 24, the first rotating body 23 is engaged with the engaging portion 121 on the outer periphery of the corresponding first rotating body 23. A notch 23m having a wall portion is provided on the side that is locked to the claw portion 61 when it is rotated in the direction in which it is directed in the locking direction. Further, as shown in FIGS. 11, 14, 21, and the like, the detection means 7 is provided in a pressing member 71 protruding from the contact surface 112 x of the housing 101 and an edge 102 b on the side opposite to the suspension of the door 102. The displacement part 72 attached to the periphery of the shaft 72a parallel to the edge part 102b and rotationally displaced by being pushed into the pressing element 71 in the closed position, and the displacement part 72 rotates and protrudes to the side. 14 presses the pressure-receiving surface 6b displaced from the shaft 6x of the restraining member 6, so that the claw portion 61 becomes as shown in FIGS. 24A to 16B as shown in FIGS. It is comprised so that it may rotate in the direction which leaves | separates from the notch 23m and goes to a non-restraining position. The restraining member 6 is urged by a spring (not shown) so as to return to the restraining position when the pushing force from the pressing member 71 to the displacement portion 72 is released. As described below, the first rotating body 23 is prestored with an operating force by a spring 124. By releasing the claw portion 61, the first rotating body 23 locks the engaging portion 121 with the operating force. Rotate in the direction to the position.

Accumulation of the operating force by the spring 124 is performed when the first rotating body 23 and the second rotating body 25 described above relatively rotate. That is, when the operation part 122 is further operated to the unlocking side as shown in FIGS. 19 and 20 from the state of FIGS. 17 and 18 in which the dial lock 103 is collated, the first rotating body 23 rotates. Then, the notch 23m moves to a position where the claw portion 61 of the restraining member 6 faces. At this time, the second rotating body 25 also rotates together. Next, as shown in FIGS. 21 and 22, when the door 102 is opened, the detection means 7 detects the state and moves the restraining means 6 to the restraining position, so that the first rotating body 23 rotates. Be bound. Thereafter, when the operating force with respect to the operating portion 122 is released, the operating body 104 protrudes by being biased by the spring 130a as shown by arrows in FIGS. 23 and 24, and the first rotating body 23 is restrained by the restraining means 6. In this state, only the second rotating body 25 rotates. Therefore, at this time, the first rotating body 23 is engaged with the second rotating body 25 by compressing the spring 130a so that the engaging portion 121 is moved from the unlocked position shown in FIGS. The actuating force that is directed to the locking position shown in FIG. 16 is accumulated. The first rotating body 23 functions as an operating force storage member of the present invention. Of course, this does not prevent the spring 130a from being provided with the required preload. When the second rotating body 25 rotates together with the operation unit 122 while the first rotating body 23 is constrained, the pin 122y of the operation unit 122 is inserted into the long hole of the first rotating body 23 as shown in FIG. It is made to move within 23y.

Next, the overall operation of this embodiment will be described, including the operations already described in part.

First, when the door 102 is in the closed position shown in FIGS. 15 and 16 and the dial lock 103 is in the non-collation state, the holding force of the lever 131 is released, and the lever 131 is urged by the spring 132f to rotate downward. In the moving position. At this time, the operation of the operation unit 122 is prohibited by the first related unit 100 C, and the engaging part 121 is in a locked position where the engaging part 121 is engaged with the engaged part 111. The pin 122y of the operation unit 122 is located on one end side of the long hole 23y of the first rotating body 23, and the restraining member 6 is attached to the first rotating body 23 by the detection means 7 detecting the closed position. On the other hand, it is held in an unconstrained position. Next, when the dial lock 103 is collated, the lever 131 is moved to the upward rotation position by the function of the dial lock 103 as shown by the arrow in FIG. The prohibition state by the first related portion 100 C is released, and the second rotating body 25 becomes movable along with the operation portion 122 and the operating body 104. Therefore, when the knob 122a of the operation unit 122 is operated as shown by the arrows in FIGS. 19 and 20, the pin 122y attaches the first rotating body 23 through one end of the long hole 23y of the first rotating body 23. As a result, the engaging portion 121 is retracted from the engaged portion 111 and is rotated and lowered from the locked position to the unlocked position, and the pin 122c of the second rotating body 25 and the operating body are rotated. The actuator 104 is pushed in while the spring 130a is compressed by the second related portion 100D including the 104 long hole 104c, and the dial is reset to zero. At the time of such zero reset, the holding force of the lever 131 is released, and the lever 131 is rotated by the spring 132 toward the downward rotation position. If the operating force of the operating unit 122 is released in this state, the first rotating body 23 simply rotates the engaging unit 121 to the locked position shown in FIGS. 15 and 16 and returns to the locked state again. . On the other hand, when the door 102 is opened as shown in FIGS. 21 and 22 while the knob 122a of the operation unit 122 is continuously picked from the state of FIGS. 19 and 20, the displacement part 72 of the detecting means 7 is pushed. 14 (b) → (a), the restraining member 6 rotates in the direction to bring the claw portion 61 closer to the first rotating body 23 as shown in FIG. The rotation of the rotating body 23, that is, the rotation of the engaging portion 121 is restricted, and the storage space of the housing 101 is opened as shown in FIGS. When the operation on the operation unit 122 is released, the operating body 104 is urged in the protruding direction by the spring 130a, and the urging force is transmitted also to the second rotating body 25 and the operation unit 122. 24, the pin 122y of the operation unit 122 moves in the elongated hole 23y of the first rotating body 23 together with the protruding operation of the operating body 104 while the rotation of the first rotating body 23 is restrained by the restraining member 6. The second rotating body 25 rotates together with the operation unit 122 while floating. At this time, the spring 124 interposed between the first rotating body 23 and the second rotating body 25 is compressed, the engaging portion 121 remains held in the unlocked position, and the operating body 104 protrudes to the next position. It will be in the reset standby state for immersion. Even if the operation portion 122 is operated again in this state, the engagement portion 121 does not change as the pin 122y only moves freely in the long hole 23y of the first rotating body 23.

Finally, when the door 102 is operated from the state shown in FIGS. 23 and 24 toward the closing position shown in FIGS. 15 and 16, the pressing element 71 of the detecting means 7 pushes the displacement portion 72 when the closing position is reached. As a result, the restraining member 6 is lifted to the position shown in FIGS. 15 and 16, and the restraint of the first rotating member 23 is released. Therefore, the first rotating member 23 is moved by the operating force stored in the spring 124. As shown in the figure, the engaging portion 121 is rotated to the locked position, and as a result, the claw portion 121a of the engaging portion 121 is engaged with the back surface around the opening of the engaged portion 111 and returns to the locked state. At this time, the restricting portion 23k shown in FIG. 13 temporarily engages with the claw portion 151a by temporarily lifting the block body 151 and passing under the claw portion 151a, and thereafter attempts to operate the operation portion 122. The operation returns to the operation prohibited state in which the rotation of the first rotating body 23 is restricted and the operation is disabled.

As described above, the locking / unlocking device 100A of the present embodiment includes the housing 101, the door 102 serving as an opening / closing member that opens and closes the opening 11 of the housing 101, the dial lock 103 provided on the door 102, and the operation unit 122. And the engagement portion 121 and the engaged portion 111 provided in the casing 101, and the door 102 is held in the closed position by engaging the engagement portion 121 and the engaged portion 111. Is.

The operation unit 122 is configured to receive an unlocking operation so that the position of the engaging part 121 with respect to the engaged part 111 can be switched from a locked position to an unlocked position. When the 102 is closed, the unlocking operation of the operation unit 122 is prohibited at the time of non-verification, the unlocking operation is allowed at the time of verification, and the related part 100C is reset to the non-verification state in conjunction with the subsequent unlocking operation. , 100D through at least the operation unit 122, and the engagement unit 121 is unlocked while accumulating the operation force toward the locking position when the unlocking operation to the operation unit 122 is released after the door 102 is opened. When the door 102 moves to the closed position again, the operating force is released and the door 102 automatically moves to the locked position. Those configured as mutually involved in relationship each other 111.

As described above, after the dial lock 103 is verified, the operation unit 122 becomes free, and the engagement unit 121 is switched from the locked position to the unlocked position only by unlocking the operation unit 122, and the dial lock 103 is not verified. Since the door 102 is opened and the door 102 is opened, the door 102 can be brought into the locked state only by moving it to the closed position again. Therefore, the locking / unlocking device 100A can be used in as few steps as possible.

Moreover, since the dial lock 103 is reset to the non-collation state in conjunction with the operation of the operation unit 122, for example, compared with a case where the dial lock 103 is reset using the relative movement of the door 102 with respect to the housing 101. Thus, it is not necessary to accurately incorporate the dial lock 103 between the housing 101 and the door 102, and it is possible to effectively realize the locking / unlocking device 100A that operates reliably with simple assembly.

Further, even if the operation force on the operation unit 122 is released after the door 102 is opened, the engaging part 121 remains held in the unlocked position, and the engaging part 121 moves to the locked position when it is moved to the closed position. Therefore, even if the engaging portion 121 and the engaged portion 111 are so-called horizontal sickle-shaped as in this embodiment, the operation of the engaging portion 121 and the closing operation of the door 102 without increasing the accuracy. Interference can be avoided, and an appropriate and reliable closed state and locked state can be realized.

In addition, since the detection means 7 for detecting whether or not the door 102 is in the closed position is provided between the housing 101 and the door 102, it is reliably detected whether or not the door 102 has reached the closed position. Thus, the engaging portion 121 can be operated, and interference with the opening / closing operation of the door 102 can be avoided accurately.

Further, the engaging portion 121 is moved from the locked position to the unlocked position by the operation of the operating portion 122, and thereafter, the operating portion 122 is released until the operating force on the operating portion 122 is released. A first rotating body 23 as an actuating force accumulating member that accumulates an actuating force for moving the first rotating body 23 from the unlocking position to the locking position; When the detecting means 7 detects that the door 102 has moved to the closed position again, the holding force by the restraining member 6 is released, and the engaging portion 121 is released by the accumulated operating force of the first rotating body 23. Since it is configured to move from the lock position to the lock position, the detection of the closing position by the detection means 7 and the release of the operating force with respect to the engaging portion 121 can be appropriately interlocked.

Furthermore, the detection means 7 includes a displacement portion 72 provided on the door 102 side, and the displacement portion 72 is displaced by contact with the presser 71 provided on the housing 101 side, whereby the first rotating body. 23, the restraining member 6 is moved from the restraining position to the non-restraining position, and in particular, the displacement part 72 and the pressing element 71 are brought into contact with and separated from the edge 102b on the side opposite to the suspension side of the door 102. Therefore, it is possible to take out the mechanical displacement accurately by incorporating it in a compact manner.

Further, when the unlocking operation is released after the dial lock 103 is reset to the non-collation state by the unlocking operation of the operation unit 122, the related unit 100C of the

related units

100C and 100D is Since the ratchet structure prohibits the unlocking operation of the operation unit 122 after the door is closed again after allowing the returning operation in the locking direction, the operation is performed after the dial lock 103 is reset to the non-verification state. It is possible to effectively prevent the part 122 from being prevented from returning in the locking direction.
