Japanese Patent Publication No. 6-60544

  By the way, in an old thing, when opening a door etc., operation of two steps, the operation which collates a dial, and the operation which turns a knob is needed. 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 another 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.

  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 order to achieve this object, the present invention takes the following measures.

  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, the unlocking operation is allowed at the time of verification, and at least the operation unit is connected through the related unit so that the unlocking operation is reset to the non-verification state in conjunction with the subsequent unlocking operation. The engaging portion is automatically moved to the locking position after the unlocking operation to the operation portion is released and before the opening / closing member moves to the closed position again. It is comprised so that it may engage with a to-be-engaged part.

  In this 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 operation unit prohibits the unlocking operation of the operation unit. 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 operation 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.

  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.

  1-3 has shown the storage apparatus B to which the locking / unlocking apparatus A of this 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 by using the 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 be able to perform an unlocking operation by turning a knob 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 engagement portion 21 is a substantially L-shaped plate made of steel or the like, and has a claw portion 21x 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 a lever 31 and an actuating 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.

  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.

  In addition, the operating body 4 and the operation unit 22 are associated with each other through the second association 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.

  In addition, 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 a state of being under 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. 8 (a), by operating the operating unit 22, the engaging part 21 is lifted to the unlocked position where the engaging part 11 is released from the engaged part 11, and the second related part D The actuator 4 is pushed in 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.

  In particular, 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 related 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.

  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 portion, and an engaging portion on the housing side, and an engaged portion on the opening / closing member side.

  Moreover, it can also comprise so that a to-be-engaged part may protrude in the shape of a sickle, and a to-be-engaged part may become the relationship which receives this.

  Further, the engaging portion 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.
