Description

  The present invention relates to a locking / unlocking device that can appropriately lock an opening / closing member such as a drawer or a door by a simple operation using a dial lock appropriately.

  This type of dial lock device is attached to a door provided with a latch, and restrains the latch from being operated by collating the dial lock, and restrains the latch when opening the door. Generally, it is configured to release.

As a specific operation for that purpose, it is necessary to return to the state where the latch is restrained again after the dial is collated and opened, and the handle is unlocked by collating the dial and turning the knob. In addition to conventional ones that are pulled, there are known ones in which the dial is collated and then the knob is turned to perform unlocking and zero reset as shown in Patent Document 1.
Japanese Patent Publication No. 6-60544

  However, such a structure requires at least two steps of operations for collating the dial and turning the knob when the door or the like is opened. For this reason, it is cumbersome, and when the door or the like is closed, it is necessary to again perform an operation for resetting the dial or restraining by latching, which further complicates the operation. Moreover, since the dials are prepared with the doors and the like being opened, the former has a problem in that it is visually recognized by those around and is not desirable in terms of security. Furthermore, in the conventional case, after closing the door etc., the knob is turned for locking, or after closing the door etc., the knob is turned for locking, and the dial is manually turned to another number. Therefore, the operation is also complicated here. That is, the conventional one has a lot of troubles from unlocking the door or the like to locking it again, and is troublesome.

  The present invention has been made paying attention to such problems, and it is possible to add a security function using a dial lock relatively easily, and to reduce the number of steps involved in locking and unlocking, thereby improving usability. The object is to provide a device.

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

  That is, the locking / unlocking device of the present invention includes a dial lock and an operating body in either the casing or the opening / closing member that opens and closes the casing, and the operating body is configured such that the opening / closing member is removed from the casing after collation of the dial lock. It is configured to operate in one direction when it is opened apart and to be pushed in as the opening and closing member approaches the casing and to operate in the other direction. It is characterized by resetting to the collation state.

  If comprised in this way, since an operation body will be operated using the operation | movement which an opening / closing member leaves | separates from a housing | casing or the operation | movement which approaches a housing | casing after collation of a dial lock, and this resets a dial to a non-collation state, It is not necessary to perform a separate operation for reset other than the opening / closing operation, and the operation can be reduced by one action. In addition, the operating body is between the housing and the opening / closing member and operates depending on whether it is pushed in or released, and the dial lock and the operating body may be provided in either the housing or the opening / closing member. In addition, while utilizing the opening / closing operation of the opening / closing member, it is possible to effectively avoid a complicated configuration in which a link or the like is disposed between the both, which hinders the storage space.

  In addition, the reset to the non-collation state mentioned here includes a mode of resetting to a specific number or a mode of randomly canceling the collation state in addition to a so-called zero reset mode. Hereinafter, the same applies to reset in a broad sense.

  As a preferable embodiment of the operating body, there is one that is pushed in when operating in the other direction, accumulates the repulsive force, and operates in one direction using the repulsive force.

In order to easily realize the operation of such an operating body, the operating body is pushed into the boundary portion between the opening and closing member and the housing at the time of closing, and is released from the boundary portion by being opened. It is preferable that they are arranged so as to protrude.
Alternatively, the operating body is housed in a space that is closed by the casing and the opening / closing member by being pushed in when the opening / closing member is closed, and is operated in a direction opposite to that when the opening / closing member is opened from the space. Those arranged so as to be opened are also suitable.
In this case, it is desirable that the operating body is pressed against the inner wall of the housing space of the housing.

  In order to effectively enhance the security function, it is desirable that the dial lock is configured to be reset to a non-verification state by using the operation of the operating body when the opening / closing member is separated from the housing.

  In order to eliminate the need for an extra operation, it is advantageous that the lock state of the opening / closing member is released when the dial lock is collated.

  For the same purpose, it is effective to use the operation of the operating body so that the opening / closing member is automatically shifted to the locked state only by moving it to the closed position next time.

  In order to further improve the operability, it is preferable that a latch mechanism including a handle is provided on the opening / closing member side, and a dial lock and an operating body are provided on the opening / closing member side.

  As a preferred embodiment of the latch mechanism, the operating force input to the handle is transmitted to the latch through the transmission system including the rotation shaft so that the latch can be released, and a part of the transmission system is disconnected. A clutch is provided at a position to switch the contact, and the dial lock and the clutch are directly or indirectly associated so that the clutch is turned off when the dial lock is not collated and the clutch is turned on when the dial lock is collated. It is done.

  The present invention can be applied to various opening / closing members. When the opening / closing member is a drawer, an operating body may be provided on either the back surface of the drawer end plate or the corresponding front surface of the housing. When the opening / closing member is a door, either the edge of the door on the hanging side, the rear surface in the vicinity of the edge or the corresponding front surface of the housing, or the edge on the anti-hanging side of the door The working body may be provided on any one of the rear surface in the vicinity of the portion or the edge or the front surface corresponding to the housing.

  Since the present invention has the configuration described above, it is possible to reset the dial lock to the non-verification state again only by opening the opening / closing member with the collating state and opening / closing the opening / closing member. Since the operation body is pushed in and released, the operation is reset, so it can be easily configured by incorporating the operation body into either the open / close member side or the housing side, simplifying the structure and reducing costs. Therefore, it is possible to provide an excellent locking / unlocking device that can also be achieved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a storage device 2 to which the locking / unlocking device 1 of this embodiment is applied. In this storage device 2, a drawer 22 as an opening / closing member is disposed in a housing 21, a latch mechanism 3 is incorporated in the drawer 22, and the drawer 22 can be moored to the housing 21 and provided on the end plate 22 a of the drawer 22. The mooring state can be released by 31, and the locking / unlocking device 1 is configured to lock and unlock the drawer 22 in the end plate 22 a of the drawer 22 while using the latch mechanism 3. When the drawers 22 are arranged in a plurality of stages, the locking / unlocking device 1 according to this embodiment realizes the locking / unlocking of the drawers 22 individually. It becomes effective.

  As shown in FIG. 2, the drawer 22 is obtained by integrally attaching an end plate 22a to the front side of the drawer body 22b. FIG. 2 shows a state in which the front decorative plate constituting the end plate 22a is removed, and various component parts are attached to the rear plate 22a1 constituting the end plate 22a.

  As shown in FIGS. 2 and 3A, the latch mechanism 3 elastically protrudes the latch claw 33 toward the side from the resin member 32 provided at the boundary between the end plate 22a and the drawer body 22b. The latch claw 33 is engaged when the drawer 22 is pushed into the recess 21b provided on the inner surface of the side plate 21a of the casing 21 constituting the storage device 2 as shown in FIG. 3 (a). Therefore, when an operating force is input to the handle 31, the latch 33 is operated in the immersion direction via the transmission system A including the rotating shaft 34.

  As shown in FIGS. 2 and 3A, the transmission system A includes a rotating shaft 34, an inverted L-shaped intermediate body 35 disposed near the end of the rotating shaft 34, and a horizontal axis of the rotating shaft 34. An arm 36 that converts rotation around the axis into rotation around the vertical axis of the intermediate body 35, and a conversion unit 37 that converts forward / reverse rotation around the vertical axis of the intermediate body 35 into unidirectional movement around the vertical axis of the latch 33. The latch 33 can be operated in the immersion direction even if the handle 31 is operated in any direction. FIG. 3B exemplifies the principle of the conversion unit 37, and the L-shaped oscillating body 37 b rotates in the same direction no matter which direction the balance member 37 a rotates due to the rotation of the intermediate body 35. The latch 33 engaged with the tip of the rocking body 37b is rotated in the immersion direction. In the case of illustration, the rocking body 37b is pressed in a direction in which the latch 33 protrudes by an elastic body 37c such as a spring.

  On the other hand, in the locking / unlocking device 1 of the present embodiment, the clutch 11 is interposed between the handle 31 and the rotary shaft 34 in the end plate 22a of the drawer 22 shown in FIGS. In order to give the cam 12 a switching operation from the locked state to the unlocked state, a dial lock 13 as an input portion is provided in the vicinity of the handle 31 of the drawer 22.

  As shown in FIGS. 5A and 5B, the handle 31 is loosely fitted to the rotary shaft 34, and the clutch 11 can rotate integrally with the rotary shaft 34 and slide in the axial direction at a position adjacent to the handle 31. 5 (c) in which the related part 11a provided in a part of the clutch 11 is engaged with the related part 31a provided in a part of the handle 31 at a position displaced from the axis of the rotating shaft 34. ) (Clutch-on state), the rotation of the handle 31 is transmitted to the rotary shaft 34 via the clutch 11, and the engagement 31 is released in the state shown in FIG. 5A (clutch-off state). Without being transmitted to the rotating shaft 34.

  As shown in FIGS. 2 and 4, the cam 12 is a plate-like member attached around the horizontal axis m to the back plate 22a1 of the end plate 22a, and the tip 12a displaced from the horizontal axis m is shown in FIGS. Thus, it is always engaged with the engaging part 11b provided in a part of the clutch 11. Then, as shown in FIG. 5A, the clutch 11 is turned off at the locking position of FIG. 6 in which the cam 12 is rotated clockwise in the front view, and in the unlocked position of FIG. As shown in c), the clutch 11 is turned on. In this embodiment, the cam 12 is elastically biased toward the unlocked position in FIG. 4 by an elastic body 15 such as a spring.

  As for the dial lock 13, since the basic mechanism itself is general, the main part of the internal mechanism is omitted, but as shown in FIG. 4, a lever 13b protrudes from the casing 13a so as to be pivotable to one side. The tip of the lever 13b is connected to the portion of the cam 12 displaced from the horizontal axis m via the connecting shaft n, and the lever 13b is rotated downward and held at that position during non-collation shown in FIG. The holding force of the lever 13b is released at the time of collation shown in FIG. That is, when the dial lock 13 shown in FIG. 6 is not collated, the cam 12 is held at the locking position against the elastic body 15, so that the handle 31 and the rotary shaft 34 are disengaged, and the handle 31 is operated. Also take a locked state that only idles. On the other hand, when the holding force of the lever 13b is released, the cam 12 is elastically urged by the elastic body 15 toward the unlocked position as described above. 4, the handle 31 and the rotary shaft 34 are connected to each other by the clutch 11, and the handle 31 is in an unlocked state in which the latch can be released.

  In this embodiment, as shown in FIGS. 2 and 4, the operating body 4 is arranged together with the dial lock 13 on a part of the drawer 22, and the drawer 22 is connected to the housing after the dial lock 13 is collated. 2 is operated in one direction indicated by an arrow P in FIG. 2 (a direction projecting rearward from the end plate 22a), and the arrow 22 is pressed by the pushing reaction force when the drawer 22 approaches the housing 21. The dial lock 13 is reset to a non-collation state by using the operation of the operating body 4.

  More specifically, as shown in FIGS. 2, 7 and 8, etc., the operating body 4 is a cylindrical body made of resin or the like disposed on the back surface in the vicinity of the side edge of the back plate 22a1 constituting the end plate 22a. It is attached to the vicinity of the back surface of the back plate 22a via a vertical axis L1 via a T-shaped support 41. Then, when the drawer 22 is pushed into the housing 21 as shown in FIGS. 8 (a) → (b) → (c) → (d), it strikes against the front surface 21x of the side plate 21 of the housing 21 and the reaction force thereof. Then, when the drawer 22 moves away from the housing 21 as shown in FIG. 8 (d) → (c) → (b) → (a), the pushing force disappears. Projecting backward. For this protruding operation, an elastic force of an elastic body 130 (see FIG. 9) described later may be used, or an elastic body may be separately incorporated at an appropriate position.

  The movement of the actuating body 4 is interlocked with a reset bar 13 c that protrudes from the dial lock 13 to the other side via the interlocking mechanism 5. As shown in FIGS. 2, 7, and 8, the interlocking mechanism 5 includes a movable bracket 51 that is attached to the front surface side of the rear plate 22 a 1 of the end plate 22 a so as to be rotatable around the support shaft L <b> 2, and the axis of the movable bracket 51. A first link 52 for connecting the portion displaced from the center L2 and the portion displaced from the axis L1 of the T-shaped support 41 to link the rotation of the support 41 and the rotation of the movable bracket 51; The second link 53 is provided to link the rotating operation of the movable bracket 51 and the projecting and retracting operation of the reset bar 13c from the casing 13a.

  As schematically shown in FIG. 9, the reset bar 13 c is biased in a direction protruding outward from the casing 13 a of the dial lock 13 by an elastic body 130 such as a spring provided therein, It is configured to reset the dial of the dial lock 13 to zero when it is urged by the elastic body 130 and protrudes from the casing 13a without affecting the dial state of the dial lock 13 when immersing against it. . As described above, the lever 13b protruding from the opposite side is held in the downward rotation position when the dial is not collated, including zero reset, and the holding force is released during the collation.

  That is, when the drawer 22 is in the closed position shown in FIG. 8D and the operating body 4 is pushed into the end plate 22a by the front surface 21x of the housing 21 and is in the immersive position, the reset rod 13c is connected via the interlocking mechanism 5. Is pushed in. At this time, if the dial lock 13 is in the non-collation state, as shown in FIG. 6, the lever 13b has a holding force in the downward rotation position, and the cam 12 is held in the locking position where the clutch 11 is turned off. Next, when the dial lock 13 is collated, the holding force of the lever 13b is released, and this serves as a trigger to move the cam 12 to the unlocking position shown in FIG. Connected and the handle 31 becomes operable. When the latch 33 is released by the handle 31 and the drawer 22 is pulled out, the operating body 4 located at the immersive position as shown in FIGS. 8 (d) → (c) → (b) → (a) is moved from the rear surface of the end plate 22a to the rear surface. The reset rod 13c that protrudes to the side and has been pushed through the interlocking mechanism 5 until then is pushed outward by the elastic force accumulated in the elastic body 130 shown in FIG. As a result, the dial lock 13 is reset to zero. At the time of this zero reset, the lever 13b is rotated to the downward rotation position and is held at that position, so that the cam 12 resists the elastic body 15 as shown in FIGS. Then, it moves to the locking position, and the clutch 11 is turned off again. Since the clutch 11 is in an off state when the drawer 22 is pushed in, the drawer 22 is moored at the storage position while the latch 33 is temporarily immersed. At this time, the operating body is immersed as shown in FIGS. 8 (a) → (b) → (c) → (d), and the reset bar 13c is pushed again against the elastic body 130. At this time, the dial lock 13 The dial maintains a zero reset state.

  As described above, the locking / unlocking device of the present embodiment includes the dial lock 13 and the operating body 4 on the drawer 22 side that opens and closes the housing 21, and the operating body 4 has the drawer 22 after the collation of the dial lock 13. It is configured to operate in one direction when being released away from the body 21 and to be pushed in as the drawer 22 approaches the casing 21 to operate in the other direction. The dial lock 13 is reset to the non-collation state.

  In this way, the operation body 4 is operated using the relative operation of the drawer 22 with respect to the housing 21 after collation of the dial lock 13, thereby resetting the dial to the non-collation state. It is unnecessary to perform a separate operation for resetting, and the operation can be reduced by one action. In addition, the operating body 4 is located between the casing 21 and the drawer 22 and operates depending on whether it is pushed or released by the counterpart member. The dial lock 13 and the operating body 4 are arranged on the drawer 2 side. Therefore, while using the opening / closing operation of the drawer 22, it is possible to effectively avoid a complicated and obstructing storage space in which a link or the like is disposed between the two.

  In this case, the operating body 4 is pushed when operating in the other direction, accumulates a repulsive force in the elastic body 130, and operates in one direction using the repulsive force. The movement in one direction and the other direction can be easily realized only by applying the elastic force of the body 130 or the like.

  In particular, the actuating body 4 is disposed so as to be immersed in the boundary portion between the drawer 22 and the casing 21 when closed, and to protrude from the boundary portion when opened. The front surface 21x of the casing 21 which is the other party to push the can be used as it is, and it is sufficient to incorporate the operating body 4 only on the drawer 22 side.

  From the viewpoint of security, the dial lock 13 is configured to be reset to the non-collation state by using the operation of the operating body 4 when the drawer 22 is separated from the housing 21, so that the drawer 22 starts to be opened. Sometimes, the collation number is reset, and it is possible to effectively avoid the collation number being visually recognized by a person in the vicinity with the drawer 22 opened.

  From the viewpoint of operability, the lock state of the drawer 22 is automatically released when the dial lock 13 is collated, and the lock is immediately released by collation even though it is a dial lock mechanism. Therefore, it is not necessary to perform another unlocking operation such as turning the knob, and the operation can be reduced by one action.

  Alternatively, the operation of the operating body 4 is used to automatically shift the drawer 22 to a state where the drawer 22 is locked only by moving the drawer 22 to the closed position next time. It is possible to smoothly shift to the locked state again without performing.

  Furthermore, since the latch mechanism 3 including the handle 31 is provided on the drawer 22 side, and the dial lock 13 and the operating body 4 are also provided on the drawer 22 side, the dial lock 13 and the handle 31 are operated in series. Therefore, operability can be remarkably improved.

  The latch mechanism 3 transmits the operating force input to the handle 31 to the latch via the transmission system A including the rotation shaft, and enables the latch to be released. A part of the transmission system A is connected and disconnected. Since the clutch 11 is provided at the switching position, the dial lock 13 is associated with the clutch 11 so that the clutch 11 is turned off when the dial lock 13 is not collated and the clutch 11 is turned on when the dial lock 13 is collated. The operation of releasing the locked state of the drawer 22 by collation of the dial lock 13 or making the drawer 22 lockable by resetting the dial lock 13 to the non-collation state is performed using a part of the existing latch mechanism 3. Therefore, it can be effectively realized, and the switching between the locked state and the unlocked state can be performed with a very slight operation. Moreover, since the operating force is not transmitted to the latch even when the handle 31 is operated at the time of locking, the situation that the latch is damaged due to an unreasonable operation can be effectively avoided.

  Since the opening / closing member is the drawer 22, the operating body 4 is provided on the back surface of the end plate 22a of the drawer 22 and the front surface of the housing 21 is used as it is. Thus, it can be set not only on the back surface in the vicinity of the side edge of the end plate 22a but also on the back surface on the upper edge side and the back surface on the lower edge side, and can be configured with a high degree of design freedom.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the dial lock 13 and the operating body 4 are provided on the drawer 22 side which is an opening / closing member, but this does not impede the aspect of providing the dial lock 13 and the operating body 4 on the housing 21 side.

  Also, the operation body 4 is operated by using the operation of approaching the drawer 22 after the collation and withdrawal of the dial lock 13 (that is, the operation when closing), thereby resetting the dial to the non-collation state. The basic effects of the present invention can be achieved.

Further, the opening / closing member is not limited to the drawer, and the present invention can be effectively applied to a door 122 as shown in FIGS. 10 and 11, for example. The thing of FIG. 10 provided the operating body 4 in the edge part of the suspension side of the door 122, or the back surface near an edge part, and comprised it so that the operating body 4 might be pushed in by the front surface 121x of the housing | casing 121 in the facing position. It is. Of course, the operating body 4 may be provided on the housing 121 side and pushed by the door 122. Alternatively, in FIG. 11, the operating body 4 is provided on the edge of the door 122 on the side opposite to the suspending side or the back surface in the vicinity of the edge, and the operating body 4 is pushed in by the front surface 121x of the housing 121 at the facing position. It is composed. Of course, in this case as well, the operating body 4 may be provided on the housing 121 side and pushed by the door 122. In these drawings, the dial lock and the transmission system for connecting the dial lock and the operating body 4 are not shown, but the dial lock is configured to be reset to a non-verification state by using the operation of the operating body 4. Needless to say.
(Second Embodiment)
12 to 14 show a second embodiment of the present invention. In these figures, the drawer 22 and the latch mechanism 3, the transmission mechanism A, the handle 31, the locking / unlocking device 1, the dial lock 13, and the like are basically the same as those in the first embodiment, and are particularly described. The description about this is omitted for the parts that do not require.

  Thus, in the present embodiment, the actuating body 104 is arranged together with the dial lock 13 on a part of the drawer 22, and the actuating body 104 is opened when the drawer 22 is separated from the housing 21 after the dial lock 13 is collated. 12 is operated in one direction indicated by an arrow R in FIG. 12 (direction to slide backward from the end plate 22a), and in the other direction indicated by the arrow S due to the pushing reaction force when the drawer 22 approaches the casing 21 (end plate). The dial lock 13 is reset to the non-collation state using the operation of the operating body 104.

  More specifically, the actuating body 104 is made of a resin or the like that is slidably engaged with a guide hole (not shown) provided on the side surface of the side plate 22b of the drawer 2 so as to be slidable back and forth. An engagement piece 104a that engages with the front surface 21x of the side plate 21a of the housing 21 from the front when pushed into the housing 21 is provided. When the drawer 22 is drawn further forward than the state of FIG. 13A, the engagement piece 104a is in a state of being separated from the front surface 21x of the side plate 21 of the housing 21 forward. When the drawer 22 is pushed into the housing 21 as shown in FIGS. 13A to 13B from FIG. 13A to FIG. 14B, the engaging piece 104a is moved to the side plate 21 of the housing 21. The actuator 104 is moved relative to the side plate 22b in a direction approaching the end plate 22a by the reaction force against the front surface 21x, and conversely, as shown in FIG. 14 (b) → (a) → FIG. 13 (b) → (a). Thus, when the drawer 22 moves away from the housing 21, the pushing force disappears, and the operating body 104 moves relative to the side plate 22b in a direction away from the end plate 22a. When the drawer 22 is further opened from the state shown in FIG. 13A, the operating body 104 is completely separated from the front surface 21x of the side plate 21 of the casing 2 again. For this protruding operation, the elastic force of the elastic body 130 shown in FIG. 9 may be used, or an elastic body may be separately incorporated at an appropriate position.

  The reset rod 13c protruded from the dial lock 13 to the other side is linked to the movement of the operating body 104 via the linkage mechanism 105. As shown in FIGS. 12 to 14, the interlocking mechanism 105 includes a movable bracket 151, a third link 152, and a second link 153. The movable bracket 151 is attached to the front side of the rear plate 22a1 of the end plate 22a so as to be rotatable around the support shaft L3, and the third link 152 is connected to the support shaft L4 set at a position displaced from the axis L3 of the movable bracket 151. The second support 153 is connected to the support shaft L5 set on the operating body 104 to link the sliding operation of the operating body 104 and the rotating operation of the movable bracket 151. The projecting and retracting operation of 13c from the casing 13a is interlocked via the support shaft L6.

  As already described with reference to FIG. 9, the reset bar 13 c is biased in a direction protruding outward from the casing 13 a of the dial lock 13 by an elastic body 130 such as a spring provided therein. The dial lock 13 does not affect the dial state when immersing against it, and the dial of the dial lock 13 is reset to zero when it is urged by the elastic body 130 and protrudes from the casing 13a. Yes. As described above, the lever 13b protruding from the opposite side is held in the downward rotation position when the dial is not collated, including zero reset, and the holding force is released during the collation.

  That is, when the drawer 22 is in the closed position shown in FIG. 14B and the operating body 104 is supported by the front surface 21x of the housing 21 and is slid to the position where it comes into contact with the back surface 22ax of the end plate 22a, the interlocking mechanism 105 is used. The reset rod 13c is pushed in the left direction in FIG. At this time, if the dial lock 13 is in the non-collation state, as shown in FIG. 6, the lever 13b has a holding force in the downward rotation position, and the cam 12 is held in the locking position where the clutch 11 is turned off. . Next, when the dial lock 13 is collated, the holding force of the lever 13b is released, and this serves as a trigger to move the cam 12 to the unlocking position shown in FIG. Connected and the handle 31 becomes operable. When the latch 33 is released by the handle 31 and the drawer 22 is pulled out, the operating body 104 in the forward position as shown in FIG. 14 (b) → (a) → FIG. 13 (b) → (a) is shown in FIG. The elastic body 130 and the like are urged to slide backward from the back surface 22ax of the end plate 22a, and the reset rod 13c that has been pushed through the interlocking mechanism 105 is pushed outward (rightward in the figure). As a result, the dial lock 13 is reset to zero. At the time of this zero reset, the lever 13b is rotated to the downward rotation position and is held at that position, so that the cam 12 resists the elastic body 15 as shown in FIGS. Then, it moves to the locking position, and the clutch 11 is turned off again. Since the clutch 11 is in an off state when the drawer 22 is pushed in, the drawer 22 is moored at the storage position while the latch 33 is temporarily immersed. At this time, the operating body 104 slides forward on the drawer 22 as shown in FIGS. 13 (a) → (b) → FIG. 14 (a) → (b), and the reset rod 13c again resists the elastic body 130. At this time, the dial of the dial lock 13 maintains the zero reset state.

  As described above, the locking / unlocking device of this embodiment also includes the dial lock 13 and the operating body 104 on the drawer 22 side that opens and closes the housing 21, and the operating body 104 has the drawer 22 after the collation of the dial lock 13. It is configured to operate in one direction when being released away from the body 21 and to be pushed in as the drawer 22 approaches the casing 21 to operate in the other direction. The dial lock 13 is reset to the non-collation state.

  As described above, the operation body 104 is operated using the relative operation of the drawer 22 with respect to the housing 21 after collation of the dial lock 13, thereby resetting the dial to the non-collation state. It is unnecessary to perform a separate operation for resetting, and the operation can be reduced by one action. In addition, the operating body 104 is located between the casing 21 and the drawer 22 and operates depending on whether it is pushed or released by the counterpart member, and the dial lock 13 and the operating body 104 are arranged on the drawer 2 side. Therefore, while using the opening / closing operation of the drawer 22, it is possible to effectively avoid a complicated and obstructing storage space in which a link or the like is disposed between the two.

  In this case, the operating body 104 is pushed when operating in the other direction, accumulates a repulsive force in the elastic body 130, and operates in one direction using the repulsive force. The movement in one direction and the other direction can be easily realized only by applying the elastic force of the body 130 or the like.

  In particular, the actuating body 104 is disposed so as to be immersed in the boundary portion between the drawer 22 and the housing 21 when closed when pushed, and project from the boundary portion when opened. The front surface 21x of the casing 21 that is the other party to push the can be used as it is, and it is sufficient to incorporate the operating body 104 only on the drawer 22 side, so that it is easy to make.

  From the viewpoint of security, the dial lock 13 is configured to be reset to a non-collation state by using the operation of the operating body 104 when the drawer 22 is separated from the housing 21, so that the drawer 22 starts to be opened. Sometimes, the collation number is reset, and it is possible to effectively avoid the collation number being visually recognized by a person in the vicinity with the drawer 22 opened.

  From the viewpoint of operability, the lock state of the drawer 22 is automatically released when the dial lock 13 is collated, and the lock is immediately released by collation even though it is a dial lock mechanism. Therefore, it is not necessary to perform another unlocking operation such as turning the knob, and the operation can be reduced by one action.

  Alternatively, the operation of the operating body 104 is used to automatically shift the drawer 22 to a state where it is locked only by moving the drawer 22 to the closed position next time. It is possible to smoothly shift to the locked state again without performing.

  Further, since the latch mechanism 3 including the handle 31 is provided on the drawer 22 side, and the dial lock 13 and the operating body 104 are also provided on the drawer 22 side, the dial lock 13 and the handle 31 are operated in series. Therefore, operability can be remarkably improved.

  As the latch mechanism 3, an operating force input to the handle 31 is transmitted to the latch 33 via the transmission system A including the rotating shaft 34, and the latch 33 can be released. A part of the transmission system A The clutch 11 is provided at a position to switch the connection and disconnection, and the dial 11 is associated with the clutch 11 so that the clutch 11 is turned off when the dial lock 13 is not collated and the clutch 11 is turned on when the dial lock 13 is collated. Therefore, the action of releasing the locked state of the drawer 22 by collation of the dial lock 13 or making the drawer 22 lockable by resetting the dial lock 13 to the non-collation state is one of the existing latch mechanisms 3. This can be effectively realized by using the unit, and the switching between the locked state and the unlocked state can be performed with very slight operation. Moreover, since the operating force is not transmitted to the latch 33 even when the handle 31 is operated at the time of locking, the situation that the latch 33 is damaged due to an unreasonable operation can be effectively avoided.

The opening / closing member is the drawer 22, and the operating body 104 is provided on the back surface of the end plate 22a of the drawer 22 and the front surface of the housing 21 is used as it is. Thus, it can be set not only on the back surface in the vicinity of the side edge of the end plate 22a but also on the back surface on the upper edge side and the back surface on the lower edge side, and can be configured with a high degree of design freedom. Further, since the operation body 104 is pushed in when the drawer 22 is closed, it is accommodated in a space closed by the casing 21 and the end plate 22a of the drawer 22, so that the appearance at the time of closing is effectively achieved. Can be improved.

In this storage device 202, a door 222 as an opening / closing member is disposed at a position to open and close the storage space of the housing 221, and a latch mechanism 203 is incorporated in the door 222 so that the door 222 can be moored to the housing 221 and attached to the door 222. The moored state can be released by the provided handle 231, and the locking / unlocking device 201 is configured to lock / unlock the door 222 in the door 222 using the latch mechanism 203.

  One end of the door 222 is attached to the side plate 221b of the housing 221 via a hinge mechanism H, and the hinge mechanism H is called a so-called take-out sign that takes the hinge shaft forward as the door 222 is opened. Is. A stepped portion 221x that is recessed forward is formed on the front surface of the side plate 221b. When the door 222 is closed, the door 222 is placed in the recessed stepped portion 221x as shown in FIG. The thickness part of the side edge 222b of this is accommodated.

  As shown in FIG. 15, the latch mechanism 203 has a latch claw 233 that elastically protrudes laterally from a resin member 232 provided to protrude from the upper and lower edges of the door 222 to the back. 233 is engaged when the door 222 is pushed into a recess provided in a not-shown portion of the front surface of the housing 221 constituting the storage device 202. When an operating force is input to the handle 231, The latch 233 is operated in the immersion direction via a transmission system including the rotation shaft 234.

  The transmission system can operate the latch 233 in the immersion direction even if the handle 231 is operated in either the left or right direction based on the same principle as that of the conversion unit 37 shown in FIG. Also in this case, the latch 233 is pressed in the protruding direction by a spring or the like.

  On the other hand, the locking / unlocking apparatus 201 according to the present embodiment includes a clutch 211 interposed between the handle 231 and the rotary shaft 234 in the door 222, and a link 212 is engaged with the clutch 211. In order to give a switching operation from the locked state to the unlocked state, a dial lock 213 as an input unit is provided in the vicinity of the handle 231 of the door 222.

  The handle 231 has a structure similar to that shown in FIG. 5 and is loosely fitted to the rotary shaft 234, and the clutch 211 is arranged so as to be integrally rotatable with the rotary shaft 234 and slidable in the axial direction at a position adjacent to the handle 231. 5 (FIG. 15) in which a related portion 211a provided in a part of the clutch 211 is engaged with a related part (not shown in FIG. 15) provided in a part of the handle 231 at a position displaced from the axis of the rotary shaft 234. In the same state as in c) (clutch on state), the rotation of the handle 231 is transmitted to the rotating shaft 234 via the clutch 211, and the state similar to that in FIG. In this state, the rotation of the handle 231 is not transmitted to the rotating shaft 234 and is free to rotate.

  The link 212 is arranged such that one end is connected to the clutch 211 via the shaft f and the other end is connected to the lever 213b described below via the shaft g so as to be movable up and down. In the same locking position, the clutch 211 is turned off in the same manner as shown in FIG. 5A, and the clutch 211 is turned in the same unlocking position as in FIG. I try to turn it on.

  As shown in FIG. 4, the dial lock 213 has a lever 213b protruding from the casing 213a so as to be pivotable to one side, and the tip of the lever 213b is connected to the link 212 described above via the shaft g. 6, the lever 213 b is lowered and held at that position during non-collation similar to that shown in FIG. 6, and the holding force of the lever 213 b is released during collation similar to that shown in FIG. 4. . That is, when the dial lock 13 is not collated, the link 212 is held at the lower locking position, so that the handle 231 and the rotary shaft 234 are disengaged, and a locked state is obtained in which the handle 231 is idled even if the handle 231 is operated. . On the other hand, when the holding force of the lever 213b is released, this serves as a trigger to raise the link 212 toward the unlocked position as in FIGS. 6 to 4, and the handle 231 and the rotary shaft 234 are moved by the clutch 211. Connected and unlocked by the handle 231 so that the latch can be released.

  In the present embodiment, the actuating body 204 is arranged together with the dial lock 213 on the suspending side of the door 222, and the actuating body 204 is opened when the door 222 is separated from the housing 221 after the dial lock 213 is collated. 16 is operated in one direction indicated by an arrow T in FIG. 16 (a direction protruding rearward from the door 222), and the other direction indicated by the arrow U (the door 222) by the pushing reaction force when the door 222 approaches the housing 221. The dial lock 213 is reset to the non-verification state by using the operation of the operating body 204.

  Specifically, the actuating body 204 is attached to the tip of an actuating rod 204 a that advances and retreats along the width direction of the door 222 in the vicinity of the back surface of the door 222, and the tip is attached to the inner side surface 221 b of the side plate 221 of the housing 201. The pressure receiving surface 204b is arranged facing the corner portion C between the concave step portion 221x and the inner side surface 221b. Then, when the door 222 performs the closing operation as shown in FIGS. 16A to 16B and FIGS. 17A to 17B, the actuating body 204 is connected to the corner portion C of the side plate 221 of the housing 221 ( At the final position, it strikes the inner surface 221b) and is pushed in by the reaction force so as to be recessed from the side edge 222b of the door 222, and conversely, as shown in FIG. 17 (b) → (a) → FIG. 16 (b) → (a). Thus, when the door 222 performs the opening operation, the corner portion C moves away, so that the operating body 204 protrudes obliquely rearward from the door 222 toward the corner portion C. When the door 222 is further opened from FIG. 16A, the operating body 204 is completely separated from the corner portion C diagonally forward. For this protruding operation, an elastic force of an elastic body 130 (see FIG. 9) described later may be used, or an elastic body may be separately incorporated at an appropriate position.

  And the base end 204a of the operating rod 204 is connected to the reset rod 213c protruding from the dial lock 213 to the other side at the interlocking portion 5 so that the movement of the operating body 204 and the reset rod 213c are interlocked. .

  Similarly to the case shown in FIG. 9, the reset bar 213 c is biased in a direction protruding outward from the casing 213 a of the dial lock 213 by an elastic body 130 such as a spring provided therein, and resists the elastic body 130. Therefore, the dial lock 213 is not affected when dialed, and the dial of the dial lock 213 is reset to zero when it is biased by the elastic body 130 and protrudes from the casing 213a. As described above, the lever 213b protruding from the opposite side is held at the downward rotation position when the dial is not collated, including zero reset, and the holding force is released during the collation.

  That is, when the door 222 is in the closed position shown in FIG. 17B and the operating body 204 is pushed into the inside of the door 222 by the corner portion C (or the inner side surface 221b) of the housing 221, the interlocking is performed. The reset bar 213c is pushed through the part 5. At this time, if the dial lock 213 is in the non-collation state, the lever 213b has a holding force in the downward rotation position and the link 212 turns off the clutch 211 as shown in FIG. Retained. Next, when the dial lock 213 is collated, the holding force of the lever 213b is released, and this serves as a trigger to move the link 212 to the unlocked position (upward position) and rotate with the handle 231 as shown in FIG. The shaft 234 is connected by the clutch 211, and the handle 231 becomes operable. When the latch 233 is released by the handle 231 and the door 222 is opened, the actuating body 204 in the immersive position as shown in FIG. 17B → (a) → FIG. The reset rod 213c that protrudes toward the corner portion C of the housing 202 on the suspending side and has been pushed through the interlocking portion 5 until then is pushed outward by the elastic force accumulated in the elastic body 130 shown in FIG. . Thereby, the dial lock 213 is reset to zero. At the time of this zero reset, the lever 213b is configured to be rotated to the downward rotation position and held at that position, and as a result, the link 212 is lowered to be similar to the state change of FIG. 4 to FIG. Moving to the locking position, the clutch 211 is turned off again. Since the clutch 211 is in an off state when the door 222 is closed, the door 222 is moored at the storage position while the latch 233 is temporarily immersed. At this time, the operating body is immersed as shown in FIGS. 16 (a) → (b) → FIG. 17 (a) → (b), and the reset rod 213c is pushed against the elastic body 130 again. The dial of the lock 213 maintains the zero reset state.
