Description

  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 capable of appropriately performing locking / unlocking of an opening / closing member through a simple operation regardless of the form of the engaging portion and the engaged portion, and a storage furniture to which the locking / unlocking device is applied.

  A conventional locking / unlocking device using this type of dial lock is attached to a door or the like having an engaging portion such as a latch, and prohibits the operation of the operation unit by setting the dial lock to a non-collating state. The engagement part is restricted so that it cannot be operated, and when opening the door, etc., the dial lock is collated to enable operation of the operation part, and when the door is closed, the dial lock is reset to the non-collation state again. Generally, it is configured as follows.

  The dial lock is desirably reset to the non-verification state again when the door or the like is opened after the collation. As a reference in this case, as shown in Patent Document 1 and the like, a password that is entered and a zero reset is performed by operating the knob with the dial set to the desired password. It has been.

Japanese Patent Publication No. 6-60544

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

  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. The locking and unlocking device that can perform the locking with the fewest possible procedure as a whole, and that can perform the locking operation when the opening and closing member is closed without being affected by the shape of the engaging portion and the like, and the application thereof The purpose is to provide storage furniture.

  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 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 allowed 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 unit through. 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.

  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.

  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. Even if the engaging part or engaged part is in the form of a sickle or a hook, it avoids the operational interference between the engaging part and the opening / closing member without increasing the accuracy, and is appropriate 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-collation.

  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

  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 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. .

  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. And the collation state of the dial lock can be reset, and it can be held in the locked state at the closed position by simply pushing the opening / closing member without depending on the form of the engaging part or the engaged part. 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. .

  Further, the operating body 4 and the operation unit 22 are associated with each other via a second related part D shown in FIG. 6 and the like, and the dial lock body 30 is reset to zero according to the operation state of the operation unit 22. ing. As shown in FIG. 4 and FIG. 6 and the like, the second related part D is mainly composed of a second rotating body 25 that is superposed so as to sandwich the engaging part 21 with the first rotating body 23. The second rotating body 25 has shaft holes 25x and 25y into which the support shaft 22x and the pin 22y of the operation unit 22 are respectively inserted, and always rotates integrally with the operation unit 22. A pin 22c protrudes from the second rotating body 25 at a position displaced from the center of rotation on the back surface of the operation section 22, and the pin 22c is formed on the upper and lower ends formed on the protruding end of the operating body 4 shown in FIG. From the state of FIG. 8 and FIG. 9 that is associated with the long hole 4c in the direction and in which the operation of the operation unit 22 is allowed, further along with the unlocking operation of the operation unit 22 in the direction indicated by the arrow in FIGS. Thus, the pin 22c is moved along with the rotation of the first rotating body 23, so that the operating body 4 is immersed. The second rotating body 25 and the operation unit 22 are interlocked with the operation (protruding operation) in the reverse direction of the operating body 4.

  Further, as shown in FIG. 3 and FIG. 4 and the like, between the first rotating body 23 and the second rotating body 25, the engaging portion 21 is interposed in the locking direction, that is, via the first rotating body 23. A spring 24 for storing an operating force for moving from the hanging position to the horizontal position is provided. Specifically, the spring 24 is of a torsion coil type whose central portion is attached to the support shaft 22x, and one end 24a is elastically provided on one side wall 25s of the fan-shaped recess 25p provided in the second rotating body 25. The other end 24b is elastically provided under a projection 23s projecting from the side surface of the first rotating body 23, and is elastic when the first rotating body 23 and the second rotating body 25 rotate relative to each other. The force is accumulated so that the engaging portion 21 attached to the first rotating body 23 can be pressed in the direction toward the locking position by using the second rotating body 25 as a scaffold. ing.

  Further, in order to restrain the engaging portion 21 to the unlocked position via the first rotating body 23, the restraining member 6 shown in FIG. 7 and the like is provided, and when the door 2 is in the closed position, the restraining member 6 Detection means 7 is provided to move the restraining member 6 to the restraining position when the restraint is released and the door 2 is opened.

  As shown in FIGS. 3, 4, 7, and the like, the restraining member 6 is attached to the first rotating body 23 at the distal end with a base end rotatably attached to an axis 6 x parallel to the support shaft 22 x of the operation unit 22. As shown in FIG. 7 and FIG. 15 and the like, the first rotating body 23 is engaged with the engaging portion 21 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. As shown in FIGS. 2, 5, 12, and the like, the detection means 7 is provided in the presser 71 protruding from the contact surface 12 x of the housing 1 and the edge 2 b on the anti-hanging side of the door 2. A displacement portion 72 that is mounted around a shaft 72a parallel to the edge portion 2b and that is rotationally displaced by being pushed into the pressing element 71 in the closed position, and the displacement portion 72 rotates and protrudes laterally. 5 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. 15A to 7B 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 the spring 24. By releasing the claw portion 61, the first rotating body 23 locks the engaging portion 21 with the operating force. Rotate in the direction to the position.

  The accumulation of the operating force by the spring 24 is performed when the first rotating body 23 and the second rotating body 25 described above relatively rotate. That is, when the operation unit 22 is further operated to the unlocking side as shown in FIGS. 10 and 11 from the state of FIGS. 8 and 9 in which the dial lock 3 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. 12 and 13, when the door 2 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 on the operating portion 22 is released, the operating body 4 is urged by the spring 30a and protrudes as shown by an arrow in FIGS. 14 and 15, 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 rotary body 23 is engaged with the second rotary body 25 by compressing the spring 30a so that the engaging portion 21 is moved from the unlocked position shown in FIGS. The actuating force that is directed to the locking position shown in FIG. 7 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 30a from being given the required preload. When the second rotator 25 rotates with the operation unit 22 in a state where the first rotator 23 is constrained, the pin 22y of the operation unit 22 is inserted into the long hole of the first rotator 23 as shown in FIG. It is made to move within 23y.

  Next, the operation of the entire embodiment will be described including the operation already described in part.

  First, when the door 2 is in the closed position shown in FIGS. 6 and 7 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 the moving 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. The pin 22y of the operation unit 22 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 3 is collated, the lever 31 is moved to the upward rotation position by the function of the dial lock 3 as shown by the arrow in FIG. The prohibition state by the first related portion C is released, and the second rotating body 25 becomes movable together with the operation portion 22 and the operating body 4. Therefore, when the knob 22a of the operation unit 22 is operated as shown by the arrows in FIGS. 10 and 11, the pin 22y biases 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 21 is retracted from the engaged portion 11 and rotated down from the locked position to the unlocked position, and the pin 22c of the second rotating body 25 and the operating body 4 are rotated. The operating body 4 is pushed in while the spring 30a is compressed by the second related part D including the long hole 4c, and the dial is reset to zero. At the time of such zero reset, the holding force of the lever 31 is released, and the lever 31 is rotated toward the downward rotation position by the spring 32. If the operating force of the operating portion 22 is released in this state, the first rotating body 23 simply rotates the engaging portion 21 to the locked position shown in FIGS. 6 and 7 and returns to the locked state again. . On the other hand, when the door 2 is opened as shown in FIGS. 12 and 13 while the knob 22a of the operation portion 22 is continuously picked from the state of FIGS. 10 and 11, the displacement portion 72 of the detecting means 7 is pushed in. Since the state is eliminated, the restraining member 6 rotates in a 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 21 is restrained, and the storage space of the housing 1 is opened as shown in FIGS. 12 and 13. When the operation on the operation unit 22 is released, the actuating body 4 is urged in the protruding direction by the spring 30a, and the urging force is transmitted to the second rotating body 25 and the operation unit 22 as well. As shown in FIG. 15, the pin 22 y of the operation unit 22 moves in the elongated hole 23 y of the first rotating body 23 along with the protruding operation of the operating body 4 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 22 while moving freely. At this time, the spring 24 interposed between the first rotating body 23 and the second rotating body 25 is compressed, the engaging portion 21 remains held in the unlocked position, and the operating body 4 protrudes and then It will be in the reset standby state for immersion. Even if the operation portion 22 is operated again in this state, the engagement portion 21 does not change as the pin 22y only moves freely in the long hole 23y of the first rotating body 23.

  Finally, when the door 2 is operated from the state shown in FIGS. 14 and 15 toward the closing position shown in FIGS. 6 and 7, the pressing element 71 of the detecting means 7 pushes the displacement portion 72 when the closing position is reached. As a result, the restraint member 6 is lifted to the position shown in FIGS. 6 and 7 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 24. As shown in the figure, the engaging portion 21 is rotated to the locked position, and as a result, the claw portion 21a of the engaging portion 21 is engaged with the back surface around the opening of the engaged portion 11 and returns to the locked state. At this time, even if the restricting portion 23k shown in FIG. 4 temporarily lifts the block body 51 and passes below the claw portion 51a, the restricting portion 23k is again engaged with the claw portion 51a and tries to operate the operation portion 22 thereafter. 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 and unlocking device according to the present embodiment includes the housing 1, 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 An engaging portion 21 and an engaged portion 11 provided in the casing 1 are provided, and the door 2 is held in a closed position by engaging the engaged portion 21 and the engaged portion 11.

Thus, the engaging portion 21 can be operated, and interference with the opening / closing operation of the door 2 can be accurately avoided.

  Further, the engaging portion 21 is moved from the locked position to the unlocked position by the operation of the operating portion 22, and thereafter, the operating portion 22 is released until the operating force on the operating portion 22 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, and a restraining member 6 that restrains the first rotating body 23 at the actuating force accumulating position, When the detecting means 7 detects that the door 2 has moved to the closed position again, the holding force by the restraining member 6 is released, and the engaging portion 21 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 21 can be appropriately linked.

  Furthermore, the detection means 7 includes a displacement portion 72 provided on the door 2 side, and the displacement portion 72 is displaced by contact with the presser 71 provided on the housing 1 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 2b on the side opposite to the suspension side of the door 2. 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 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 prohibits the unlocking operation of the operation unit 22 after the door is closed again after allowing the returning operation in the locking direction, the operation is performed after the dial lock 3 is reset to the non-verification state. It is possible to effectively prevent the part 22 from being prevented from returning in the locking direction.

  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.
