Description

  The present invention makes it possible to use not only a dedicated card but also a general card such as a credit card or a commuter pass card, and an electric signal erased by operating a numeric keypad at the time of locking again after emergency unlocking The present invention relates to a card key / keypad type lock device having a simple structure and not requiring input of a record.

  Conventionally, when performing emergency unlocking during locking with a card, a numeric keypad, and a normal use key, it is common to release the electrical signal recording of the numeric keypad and unlock it once. Therefore, in order to lock again after the emergency unlocking, the erased electrical signal record must be input again by operating the numeric keypad.

  Further, as a conventional card key type lock device, there is a technique disclosed in Patent Document 1 which has been filed and registered by the applicant of the present application. In other words, when the lock is not locked, this card key type lock device has the actuating plate pivoted and urged by a spring in the housing recess of the base plate so that the tip side rises at a required angle. It is located on the upper surface side of the card and has left the card key slot.

  At this time, the engaging pin of the latch of the cylinder lock is engaged with the engaging recess of the guide piece provided in the opening of the operating plate in a compressed state, and the locking plate is further urged by the spring to form the slide groove. Shifted to the front end side, and the pin stopper on the tip protrudes upward from the tip of the long hole in the base plate and locks the engagement pin of the cylinder lock, thus preventing the cylinder lock latch from turning by key operation is doing.

  In such a state, the card key is inserted from the card key insertion slot and stored in the recess of the base plate on the bottom of the casing. At this time, the rear end edge of the card key is the locking piece at the rear end of the lock locking plate. In order to retract the lock locking plate in the slide groove of the base plate against the spring force of the spring, the pin stopper at the tip also retracts in the long hole and locks the cylinder lock to the engagement pin. To release.

  Therefore, when the key inserted into the lock hole of the cylinder lock is rotated, the latch engaging pin moves along the guide hole of the lock mounting plate, and slides in the recess of the guide piece of the operating plate. The latch is rotated about 90 degrees while pressing and rotating the operation plate, and protrudes from the casing and is inserted into the recess of the case body. As a result, the door plate is locked and locked to the case body in a closed state.

  When a dedicated card key is used as the card key, the guide piece is fitted into the fitting recess of the frame at the rear of the base plate. Thereby, when the dedicated card key is stored in the recess of the base plate on the bottom plate of the casing, the recess provided on the rear edge of the card key is engaged with the hemispherical engagement body of the guide piece, The lock locking plate is retracted until the cylinder lock can be locked.

  When a general card key (credit card, commuter pass card, etc.) is used as the card key, the guide piece fitted in the fitting recess of the frame at the rear of the base plate is removed. As a result, when the card key is stored in the recess of the base plate on the bottom plate of the casing, the rear edge of the card key comes into contact with the inside of the frame, so that the lock locking plate is retracted to a state where the cylinder lock can be locked. .

Thus, when the cylinder lock is locked, the latch engagement pin presses and holds the operating plate downward, and the card key stopper is inserted through the hole in the base plate and protrudes into the card key insertion slot. Therefore, both removal of the internal card key and insertion of a new card key are prevented.
Japanese Patent No. 3692250

  However, in the past, when performing emergency unlocking, the electrical signal recording of the numeric keypad must be released and unlocked. Since it is necessary to input again by operating, it becomes a very troublesome work.

  In Patent Document 1, when a dedicated card key is used as a card key, the guide piece is fitted into the fitting recess of the frame at the rear of the base plate corresponding to the position of the recess of the dedicated card key. When using a general card key (credit card, commuter pass card, etc.) as a card key, the guide piece fitted in the fitting recess of the frame at the rear of the base plate is removed. For this purpose, the entire cover of the casing must be removed, and the attachment of the cover to the casing is performed using a large number of screws, bolts, nuts, and the like, which makes the attaching / detaching operation very troublesome.

  Therefore, the present invention has been devised in view of the conventional circumstances as described above, and can be emergency unlocked mechanically and temporarily while leaving the first electric signal recording by the numeric keypad. This makes it unnecessary to perform the locking operation again by operating the numeric keypad and removes a number of screws, bolts and nuts when removing or replacing the guide piece according to the type of card key. It is an object of the present invention to provide a card-key / ten-key lock device that allows a guide piece to be easily removed or exchanged without performing a cumbersome operation such as removing the entire cover.

  In order to solve the above-described problems, in the present invention, the link lever is formed by penetrating from the inner center of the key insertion hole of the cylinder lock to the lock mounting plate, and is always urged toward the inside of the cylinder lock. A pin and a link lever pivotally mounted on the lower surface side of the lock mounting plate, connected to the tip of the link lever pin, and a link lever having a pressing piece for pressing the lock lever, and by inserting a master key When the link lever pin is pushed, the link lever is swung, and the pressing piece of the link lever presses the lower end of the lock lever so that the lock lever is retracted from the engaging portion of the latch in the disengagement direction. The rotation of the latch through the master key is allowed.

  The lock of the latch in the cylinder lock is released by inserting a regular card key, and the lock lever is retracted from the latch engagement portion in the direction of disengagement through the solenoid by operating the numeric keypad, and the latch is rotated by 90 degrees. Within the range, the solenoid energization input switches are arranged at the upper (unlocked) position and the left (locked) position of the cylinder lock, respectively, and when the latch rotates in the unlocking direction or locking direction, the upper side (unlocking) ) Or the left side (locking) position switch is turned on and the solenoid is energized to lock the engaging portion of the latch with the lock lever, thereby preventing the unlocking.

  The casing includes a guide piece cover that closes an opening formed to expose a plurality of guide piece mounting portions behind the base plate, and the guide piece cover is removed by opening the opening by removing the guide piece cover. The mounting position can be changed.

  According to the present invention, the emergency unlocking can be performed mechanically and temporarily while the electrical signal recording by the first numeric keypad is left, thereby eliminating the need to perform the locking operation again by operating the numeric keypad again. At the same time, when removing or replacing the guide piece according to the type of card key, the guide piece can be removed without having to perform the troublesome work of removing the entire cover of the casing by removing many screws, bolts, nuts, etc. Can be easily removed or replaced.

  That is, the present invention includes a link lever pin that is arranged to penetrate from the inner center portion of the key insertion hole of the cylinder lock to the lock mounting plate and is always urged toward the inside of the cylinder lock, and is rotated to the lower surface side of the lock mounting plate. The link lever pin is movably pivoted and has a link lever having a link portion with the tip of the link lever pin and a pressing piece portion for pressing the lock lever, and the link lever pin is pushed and linked by inserting the master key. The lever is swung and the push piece of the link lever pushes the lock lever to retract the lock lever from the latch engagement portion in the disengagement direction, and the rotation of the latch via the master key is performed. Because it was allowed, the emergency unlocking can be performed mechanically and temporarily with the electrical signal recorded by the first numeric keypad remaining, so that It can be made unnecessary to be locked operation again by operating the over.

  Also, solenoid energization input switches are arranged at the upper (unlocked) and left (locked) positions of the cylinder lock within the 90 degree rotation range of the latch, respectively, and the latch rotates in the unlocking or locking direction. In this case, the upper (unlocked) position or the left (locked) position switch is turned on and the solenoid is energized to lock the latch engaging portion with the lock lever, thereby preventing the unlocking. Therefore, it is possible to temporarily disable locking / unlocking while keeping the electrical signal recording by the first numeric keypad.

  The casing includes a guide piece cover that closes an opening formed to expose a plurality of guide piece mounting portions behind the base plate, and the guide piece cover is removed by opening the opening by removing the guide piece cover. Since the mounting position can be changed, when removing or replacing the guide piece according to the type of card key, the troublesome work of removing the entire casing cover by removing many screws, bolts and nuts, etc. Even without this, the guide piece can be easily removed or replaced.

  Further, as shown in FIGS. 5 and 6, a solenoid 31 is attached to the upper surface of the lock attachment plate 3 via the lock mechanism base 30 adjacent to the cylinder lock 11. As shown in FIG. 8, the movable shaft 32 is inserted into the solenoid 31 via a spring 33, and the movable shaft 32 is attracted and retracted into the solenoid 31 against the elastic force of the spring 33 by electromagnetic force generated by energization. It is what is done. A connecting bar 34 is fitted at a right angle to the tip of the movable shaft 32 so as to lock the spring 33, and one end of the connecting bar 34 is an upright side surface of the lock mechanism base 30 on the lock mounting plate 3. It is rotatably mounted in a hole at one end of a solenoid lever 36 which is inserted into a support shaft 35 protruding from the shaft and made swingable.

  Further, a hole on the proximal end side of an arm-shaped lock lever 37 is rotatably mounted on the support shaft 35 adjacent to the solenoid lever 36, and an L-shape is formed on the proximal end side of the lock lever 37. The bent operation piece 38 is inserted into an engagement hole 36a having a wide rectangular opening formed in the substantially center of the solenoid lever 36 with an arbitrary backlash, and is inserted into the support shaft 35 from the side surface. It is locked by fitting a C-ring shaped retaining ring 39.

  At the tip of the lock lever 37, an L-shaped lock piece 37a is formed 90 degrees away from the operating piece 38, and the lock lever 37 is rotated around the support shaft 35. Thus, the latch 10 is suspended by a notch-shaped engaging portion 10a formed on either the left or right side of the latch 10 (see FIGS. 5 and 6).

  At this time, a helical spring 40 is wound around the support shaft 35 between the solenoid lever 36 and the lock lever 37, and one end of the helical spring 40 is hung on the base end side of the lock lever 37. The end is hung on the inner edge of the locking hole 36a of the solenoid lever 36, so that the operating piece 38 is always in pressure contact with the inner edge of the locking hole 36a. Therefore, the L-shaped lock piece 37a on the distal end side of the lock lever 37 is always urged toward the latch 10 as shown in FIGS.

  As shown in FIGS. 5 and 6, the solenoid SW energization input switch SW <b> 1 is located between the upper (unlocked) position and the left (locked) position of the cylinder lock 11 within the 90-degree rotation range of the latch 10. , SW2 are arranged, and when the latch 10 rotates in the unlocking direction or the locking direction, the switches SW1 and SW2 in the upper (unlocking) position or the left (locking) position are turned on to energize the solenoid 31. Then, the movable shaft 32 is extended out of the solenoid 31 against the elastic force of the spring 33 by electromagnetic force, whereby the lock piece 37a of the lock lever 37 is engaged with the engaging portion 10a of the latch 10 via the solenoid lever 36. Hang. As a result, the rotation of the latch 10 is prevented, and the lock piece 37a of the lock lever 37 with respect to the notch-shaped engaging portion 10a of the latch 10 is not operated even if the key is inserted into the cylinder lock 11 again and turned. The lock by is maintained and cannot be unlocked.

  As shown in FIGS. 6, 7, 9, and 10, the link lever pin 41 is urged by a spring (not shown) from the inner center of the key insertion hole of the cylinder lock 11 to the lock mounting plate 3. In the state where it is inserted, it protrudes on one side of a link lever 44 pivotally attached via a support shaft 43 to a shaft support plate 42 disposed opposite to the lower surface of the lock mounting plate 3. The leading end side of the link lever pin 41 is connected to the connected portion 45 by biting. A push piece 44a is projected from the end of the link lever 44, and the triangular protrusion-like anchoring portion 37b on the proximal end side of the lock lever 37 is pressed by the push piece 44a. The lock piece 37a on the distal end side of the 37 is retracted from the engagement portion 10a of the latch 10 in the disengagement direction.

  That is, the link lever pin 41 is always urged via a spring toward the key insertion hole, and when the normal use key K1 is inserted into the key insertion hole as shown in FIG. 9, the tip of the key K1 The pressing piece 44 a of the link lever 44 does not contact the link lever pin 41 and does not press the triangular protrusion-like anchoring portion 37 b on the base end side of the lock lever 37, and the lock lever 37 tip side The engagement between the locking piece 37a and the engaging portion 10a of the latch 10 is maintained.

  On the other hand, as shown in FIG. 10, when emergency unlocking is performed, when the master key K2 whose tip slightly protrudes compared to the normal use key K1 is inserted into the key insertion hole, the tip of the key K2 is the link lever. The pin 41 is pressed, the link lever 44 is swung, and the triangular protrusion-like suspension portion 37b on the proximal end side of the lock lever 37 is pressed by the pressing piece portion 44a of the link lever 44, whereby the tip of the lock lever 37 The lock piece 37a on the side is retracted from the engaging portion 10a of the latch 10 in the disengagement direction, and the latch 10 can be unlocked via the master key K2 to be unlocked.

  Next, an example of use and operation of the best mode configured as described above will be described.

  First, the case of normal use by inserting the regular card key 16 and operating the numeric keypad K3 will be described. The door plate 6 is opened to store the article in the locker, and the regular card key 16 is inserted into the insertion slot of the card key 16 of the apparatus main body. At this time, as shown in FIGS. 11 and 12, the engagement recess 16a at the center of the rear end of the card key 16 engages with the engagement body 15b of the guide piece 15, and at the same time the rear end edge of the card key 16 is locked. A pin stopper 5a at the front end is also a long hole so that the locking plate 5 is brought into contact with the locking piece 5b at the rear end of the locking plate 5 and retreats in the slide groove 2g of the base plate 2 against the spring force of the spring 7. The inside of 2h is retracted, and the locking of the cylinder lock 11 with respect to the engaging pin 9 is released. In this state, the movable shaft 32 of the solenoid 31 is in an extended state, and the latch 10 is locked by a lock lever 37.

  When the numeric key K3 shown in FIG. 1 is pressed for 4 digits and then the input button is pressed, the movable shaft 32 of the solenoid 31 is retracted and the lock piece 37a at the tip of the lock lever 37 is raised to the unlock position. For this reason, the latch 10 is released from the locking state by the lock piece 37a and becomes free.

  The inserted normal use key K1 is turned to the left as it is, and the latch 10 is turned 90 degrees and locked. As a result, the door plate 6 is locked. However, when the latch 10 is turned to the left, the contact of the switch SW1 located on the lower side is pushed and turned on, and the movable shaft 32 of the solenoid 31 is again in the extended state. Thus, the lock piece 37a at the tip of the lock lever 37 is lowered to the lock position. For this reason, the latch 10 is engaged and fixed by the lock piece 37a as it is to maintain the locked state.

  Since the ten key K3 is not unlocked even when the article after the normal use key K1 is pulled out is being stored and the key K1 is inserted and turned again, the lock to the notch-shaped engaging portion 10a of the latch 10 is achieved. Since the locking of the lever 37 by the lock piece 37a is maintained, the unlocking cannot be performed.

  Therefore, when the numeric key K3 is pressed again and the input button is pressed, the movable shaft 32 of the solenoid 31 is retracted, the lock piece 37a of the lock lever 37 is raised to the unlocked position, and the latch 10 is released. In this state, the normal use key K1 is turned 90 degrees to the right to shift from the locked state of the door plate 6 by the latch 10 to the unlocked state.

  In this way, when the latch 10 is turned 90 degrees to the right, the contact of another switch SW2 located on the upper side is pushed and turned ON, and the movable shaft 32 of the solenoid 31 is again extended and the lock lever. The lock piece 37a at the tip of 37 is lowered to the lock position. Accordingly, the latch 10 is locked by the lock piece 37a, and locking in this state cannot be performed unless the numeric keypad K3 is unlocked.

Next, the case of emergency unlocking by inserting the long master key K2 will be described.
First, as shown in FIG. 9, even if the normal use key K <b> 1 is inserted into the key insertion hole, the key tip does not contact the link lever pin 41, and the pressing piece 44 a of the link lever 44 is on the proximal end side of the lock lever 37. A certain triangular protrusion-like hanging portion 37b is not pressed. Accordingly, the engagement of the engaging portion 10a of the latch 10 by the lock piece 37a on the distal end side of the lock lever 37 is maintained, and the unlocking state remains impossible.

  On the other hand, as shown in FIG. 10, when the master key K2 having a slightly protruding tip is inserted into the key insertion hole during emergency unlocking, the tip of the master key K2 presses the link lever pin 41. The link lever 44 is swung. Then, the triangular protrusion-like anchoring portion 37 b on the proximal end side of the lock lever 37 is pressed by the pressing piece portion 44 a of the link lever 44, whereby the locking piece 37 a on the distal end side of the lock lever 37 is engaged with the latch 10. Retracted from the portion 10a in the disengagement direction. Therefore, the rotation of the latch 10 using the master key K2 is allowed and unlocking is possible.

  When the guide piece 15 is removed or replaced, as shown in FIG. 13, the left and right screws 23 of the guide piece cover 22 are removed, the guide piece cover 22 is removed, the opening 21 is opened, and the base plate is removed. 2 After the rear frame 2c is exposed, the guide piece 15 is removed or replaced from the fitting recess 2k.

  At this time, as shown in FIG. 14, when a dedicated card key having an engagement recess 16 a in which the engagement body 15 b of the guide piece 15 fits at the center of the rear end of the card key 16, the taper of the guide piece 15 is used. The legs 15a are fitted into fitting recesses 2k in the center of the frame 2c of the base plate 2.

  Further, as shown in FIG. 15, when a dedicated card key having an engagement recess 16a in which the engagement body 15b of the guide piece 15 fits at a position shifted laterally from the center of the rear end of the card key 16 is adopted. The taper leg 15a of the guide piece 15 is fitted into the fitting recess 2k located at a position shifted laterally from the center of the frame 2c of the base plate 2.
