Description

  The present invention relates to a lock provided on a door such as a storeroom having an internal space in which a person can go in and out.

  For example, when the sliding door of a storeroom installed outdoors is unlocked, the sliding door itself may open due to a slight impact or vibration due to the wind even if it is closed, and the user intends to close the sliding door. In fact, it may be opened by rebound of the sliding door itself. And in a conspicuous environment, a situation where the sliding door is left unattended with a slight opening may induce theft, and the sliding door is unlocked while the storage is unattended. Even if it is for a short time, it is not preferable for crime prevention.

  However, when an operator enters / exits an object into / out of the storage room while holding the object or continuously, it is difficult or complicated to lock and unlock the sliding door using a key. There may be a situation where the storage door is unavoidably left unattended even for a short time.

  Therefore, the lock 71 shown in FIG. 33 can be temporarily locked and unlocked by rotating the outside knob 73 without requiring a key operation, in addition to the actual locking and unlocking performed by inserting a key into the key insertion slot 72. (See Patent Document 1). That is, in the storeroom using the lock 71, it is possible to achieve both high crime prevention and operability by locking the sliding door at night when it is not used and using the temporary unlocking during use.

  By the way, when working in the storeroom, for example, a child is mischievously locked from the outside (temporary lock or this lock), or another person accidentally locks without knowing that there is a person in the storeroom. Can be considered. In this case, in order to allow a person trapped in the storage room to escape by himself, it is necessary to be able to perform temporary unlocking and full unlocking from within the storage room.

  In this regard, in the lock shown in FIG. 33, by temporarily operating the internal knob 74 in a predetermined direction or sliding the internal lock knob 75 in a predetermined direction, the temporary unlocking and the actual unlocking can be performed from the inside of the storage. Yes.

  However, because of the ease of work and the peace of mind that comes from the brightness, the storage room is often used exclusively during the daytime, but the interior of the storage room is relatively dark even during the daytime. Below, it may be difficult to turn the internal knob 74 in a predetermined direction or slide the internal lock knob 75 in a predetermined direction.

  In the lock shown in FIG. 33, when the main lock is performed from the outside of the warehouse, the external knob 73 is operated to temporarily lock the lock, and then the key is inserted into the key insertion slot 72 to perform the final lock. However, there is a drawback that two actions are required.

  The present invention has been made in consideration of the above-mentioned matters, and its purpose is to provide a lock that contributes to the simplification of the unlocking operation from the inside of the warehouse and the realization of this locking operation from the outside of the warehouse with one action. There is to do.

In order to achieve the above object, a lock according to the present invention includes a main body case, a locking member that protrudes to the side of the main body case and can be changed between a locking posture and an unlocking posture, and a front side of the main body case. It is arranged, one end side is a lock button, the other end side is an unlock button, and either one of the lock button or the unlock button receives a pushing operation in the backward direction and rotates so that the other moves forward The seesaw member that transmits the rotation of the seesaw member when the locking button or the unlocking button receives a backward pushing operation to the locking member, and the locking when the locking button is in the retracted position. The member takes a locking posture, and when the unlocking button is in the retracted position, the locking member is arranged on the back side of the seesaw member and a transmission member for taking the unlocking posture, and pushes forward. Push to receive operation And when the push button is pushed forward when the lock button is in the retracted position, the push button contacts the lock button to advance the lock button, The locking member is configured to take an unlocking posture, and is further rotated by a key inserted from the front to stop at a locked position and an open position, and interlocked with the cylinder lock, When the cylinder lock is in the locked position, it is positioned at a restriction position that restricts the movement of the transmission member to restrain the locking member in the locking posture, and when the cylinder lock is in the open position, the restriction is A restraining member located at a release position that is not performed, and provided on the restraining member, and restricts movement of the transmission member when the restraining member is located at the restriction position. And a locking cam that is unlocked when the locking member leaves the restricting position, and the cylinder lock is in the locked position. When the push button receives a forward pushing operation, a release cam interlocked with the push button comes into contact with the lock cam and releases the lock of the lock cam with respect to the transmission member. (Claim 1) .

In the above lock, when the restraining member moves from the release position to the restricting position when the locking member is in the unlocking posture, the restraining member is engaged with the transmission member via the locking cam. It may be configured to move while stopping and to move the transmitting member to cause the locking member to take a locking posture (claim 2 ).

In the above-described lock, as the cylinder lock moves from the open position to the lock position, the release cam comes into contact with the locking cam, and the unlocking mechanism is provided with a stopper that is interlocked with the release cam in the advance position. You may be comprised so that it may be in the state stopped in the position which prevents the movement to the back of a button (Claim 3 ).

  In this invention, the lock | rock which contributes to the simplification of the unlocking operation from the inner side of a store | warehouse | chamber, and realization of this locking operation from the outer side of the store | warehouse | chamber by one action is obtained.

  That is, in the lock of the invention according to each claim of the present application, even when a person is trapped in a storeroom or the like to which the lock is attached, the person simply unlocks the push button from the inside of the warehouse. Since this unlocking operation is very simple, it is easy to escape from the storage room even if it is dark. In addition, if the operation on the push button is only the unlocking operation by the push operation, the locking operation will not be performed from the inside of the warehouse, so the person trapped in the storeroom panics and the unlocking operation and the locking operation There is no such thing as repeating.

In the lock of the invention according to claim 2 , when the main locking is performed using the key, it is possible to perform the main locking as it is even in the unlocked state as well as the locking member in the locked state.

In the lock of the invention according to claim 3 , even when the unlock button is pressed with a strong force in the locked state, the unlocking can be surely prevented by the action of the stopper.

  Embodiments of the present invention will be described below with reference to the drawings.

  The lock shown in FIGS. 1A to 1C and FIG. 2 is, for example, installed in a storage room, a garage, a sliding door of a warehouse, or the like. This lock can be applied not only to a storeroom, a garage, and a warehouse, and can also be installed on a member other than a sliding door, such as a hinged door or a pillar, but a case where it is installed on a sliding door of a storeroom will be described below.

  As shown in FIGS. 1 (B) and 2, a seesaw member 3 having a lock button 1 and an unlock button 2 and a key insertion slot 5 into which a regular key 4 can be inserted are arranged on the front surface of the lock. As shown in FIG. 1A, a push button 6 is provided on the back of the lock. The lock is installed on the sliding door of the storage room so that the front surface faces the outside of the storage room and the back surface faces the inside of the storage room.

  Further, as shown in FIG. 2, a locking member 8 protrudes on the side of the lock main body case (lock case) 7, and this locking member 8 is shown in FIGS. 3 (A) and 5 (A). It can be changed to a sideways locking posture and a downward unlocking posture shown in FIG. Here, the locking member 8 in the locking posture can be locked to a receiving bracket (not shown) provided at an appropriate part of the storage, and in this locked state, the sliding door cannot be opened. In addition, the locking member 8 in the unlocked posture is not locked to the receiving bracket, and when the locking member 8 is not locked to the receiving bracket, the sliding door is allowed to open. 1 (A) to 1 (C) and FIGS. 18 (A) to 18 (D) depict a guard portion 9 that projects downward from the main body case 7 and protects the locking member 8 in the unlocked posture. However, it is omitted in other drawings.

  The lock is obtained by (1) temporary locking operation by the locking button 1, temporary unlocking operation by the unlocking button 2, (2) main locking operation and main unlocking operation by the key 4, (3) unlocking by the push button 6. Locking operation (temporary unlocking operation or temporary unlocking and permanent unlocking operation) can be performed. Hereinafter, the contents of each operation and the configuration for realizing each operation will be described.

  First, (1) the temporary locking operation with the locking button 1 and the temporary unlocking operation with the unlocking button 2 refer to the backward pushing operations with respect to the locking button 1 and the unlocking button 2. The posture can be changed. That is, as shown in FIGS. 3 (A) and 3 (B), when the locking button 1 is in the retracted position, the locking member 8 takes the locking posture, and as shown in FIGS. 4 (A) and (B), In a state where the unlocking button 2 is in the retracted position, the locking member 8 takes the unlocking posture.

  Next, the outline of the mechanism for realizing the operation (1) will be described with reference to FIG. 8. The movement of the locking button 1 or the unlocking button 2 that receives the pressing operation moves in the left-right direction of the seesaw member 3. Between the seesaw member 3 and the locking member 8, the rotational motion is converted into a rotational motion around the extending rotational shaft portion 10, and this rotational motion is converted into a rotational motion around the rotational shaft 11 extending in the front-rear direction of the locking member 8. Is provided with a transmission member 12 that is slidable in the vertical direction (direction perpendicular to the rotary shaft 10 and the rotary shaft 11).

  More specifically, first, as shown in FIG. 8, the seesaw member 3 has a locking button 1 on one end side and an unlocking button 2 on the other end side. And in the center part of the right and left side surface of the seesaw member 3, the rotating shaft part 10 which protrudes outward is provided, respectively, and each rotating shaft part 10 is provided with the support hole 13 (FIG. 17 (FIG. 17 (FIG. 17) provided in the main body case 7). B), (D) and (E)), and the seesaw member 3 is held by the main body case 7 so as to be rotatable (swingable). Accordingly, when either the locking button 1 or the unlocking button 2 receives a backward pushing operation and moves backward, the seesaw member 3 rotates so that the other moves forward, and anyone can easily operate the seesaw member 3. It has a possible shape (universal design).

  Here, the main body case 7 is attached to a mounting hole of a sliding door that is not shown, and is shown in the front cover 7A shown in FIGS. 17A to 17E and FIGS. 18A to 18D. A screw member 16 (see FIG. 1 (A)) that is formed of a back cover 7B and penetrates through holes 15 provided in the back cover 7B is screwed into a plurality of screw holes 14 provided in the front cover 7A. Thus, the covers 7A and 7B are integrated. A support hole 13 that supports the rotary shaft portion 10 of the seesaw member 3 is provided in the front cover 7A.

  Further, as shown in FIGS. 6 and 8, the seesaw member 3 includes a seesaw body 3A (see also FIGS. 19A to 19D) and an unlocking display attached to one end of the seesaw body 3A. A plate 3B (see also FIGS. 20A to 20D) and a locking display plate 3C attached to the other end of the seesaw body 3A (see also FIGS. 21A to 21E). The unlocking display board 3B is colored in blue, and the locking display board 3C is colored in red. Thus, when the blue unlocking display board 3B is visible, the unlocked state is indicated, and when the red unlocking display board 3C is visible, the unlocked state is known at a glance. It is excellent.

  Further, the rotary shaft portion 10 of the seesaw member 3 is provided separately from the seesaw body portion 3A, and the female shaft portion 10A shown in FIGS. 22 (A) to (C) and FIGS. 22 (D) to (F). ) And a spring 10C (see FIG. 22G). That is, the female shaft portion 10A has a cylindrical portion 17 extending in the left-right direction, and a spring 10C and a rod-shaped portion 18 extending in the left-right direction of the male shaft portion 10B are inserted into the cylindrical portion 17, and the female shaft The portion 10A and the male shaft portion 10B are connected in a state of being biased in a direction away from each other by the spring 10C. In this state, the end portion 19 of the female shaft portion 10A and the end portion 20 of the male shaft portion 10B are through holes 21 provided on the left and right side surfaces of the seesaw body portion 3A (see FIGS. 19B to 19D). ). A protrusion 22 (see FIGS. 22E and 22F) is formed on the outer peripheral surface of the rod-shaped portion 18, and a groove 23 for receiving the protrusion 22 is formed in the cylindrical portion 17 (FIGS. 22A and 22B). Therefore, the rod-like portion 18 inserted into the tubular portion 17 does not rotate with respect to the tubular portion 17.

  On the other hand, the locking member 8 is configured as shown in FIGS. 24A and 24B and has a through hole 25 inserted into the rotary shaft 11 standing on the receiving plate 24 attached to the main body case 7.

  Here, the receiving plate 24 is configured as shown in FIGS. 25 (A) to 25 (D), and a plurality of screw holes 26 (see FIG. 17 (B)) provided in the front cover 7A are attached to the receiving plate 24. The receiving plate 24 is integrated with the front cover 7A by screwing a screw member (not shown) penetrating the through hole 27 provided. Moreover, as shown in FIG. 7, the rotating shaft 11 is joined to the appropriate position of the lower part of the receiving plate 24 by welding, for example.

  Further, the claw member 28 shown in FIGS. 26A to 26C is joined and integrated with the locking member 8 as shown in FIG. For this reason, the locking member 8 is provided with a through-hole (or recessed portion) 8a into which the protrusion 28a of the claw member 28 is fitted. The claw member 28 is also formed with a through hole 28b that is penetrated by the rotary shaft 11.

  On the other hand, the transmission member 12 is configured as shown in FIGS. 23A to 23D, and is formed between a pair of projecting portions 29 projecting rearward provided on the back surface of the seesaw member 3 (seesaw body portion 3 </ b> A). It has the convex part 30 which fits into a recessed part (refer FIG. 8). The transmission member 12 is also formed with a recess 31 into which one end of the claw member 28 is fitted.

  With the above configuration, as shown in FIG. 8, when a temporary unlocking operation with the unlocking button 2 is performed while the locking member 8 is in the locking posture, a pressing operation on the unlocking button 2 (see the solid arrow) ) Is converted into a rotational motion around the rotational shaft portion 10 of the seesaw member 3, and this rotational motion is a straight line of the transmission member 12 having the convex portion 30 that fits into the concave portion between the pair of projecting portions 29 of the seesaw member 3. Converted to motion (slide). And this linear motion is converted into the rotational motion around the rotating shaft 11 of the locking member 8 in which the claw member 28 fitted into the recess 31 of the transmission member 12 is integrated, and the locking member 8 takes the unlocking posture. become.

  On the contrary, when the temporary locking operation by the locking button 1 is performed while the locking member 8 is in the unlocking posture (see the broken arrow), the movement opposite to the above occurs, and the locking member 8 has the locking posture. It will be in the state to take.

  Accordingly, the transmission member 12 transmits the rotation of the seesaw member 3 when the locking button 1 or the unlocking button 2 receives a backward pushing operation to the locking member 8, and when the locking button 1 is in the retracted position. The locking member 8 takes a locking posture, and when the unlocking button 2 is in the retracted position, the locking member 8 takes the unlocking posture.

  Next, (2) the main locking operation and the main unlocking operation with the key 4 refer to a rotation operation performed by inserting the key 4 into the key insertion slot 5 (see FIG. 1B). It is possible to change between a locked state where the temporary unlocking operation is impossible and an open state where the temporary unlocking operation and the temporary locking operation can be performed freely. That is, as shown in FIG. 5 (A), when the cylinder lock 32 rotated by the key 4 inserted from the key insertion port 5 is stopped at the lock position, a temporary unlocking operation cannot be performed. As shown in FIGS. 3A and 4A, when the cylinder lock 32 is stopped at the open position, the temporary unlocking operation and the temporary locking operation can be freely performed.

  Next, a mechanism for realizing the operation (2) will be described. First, the cylinder lock 32 into which the key 4 is inserted from the front is configured as shown in FIGS. 27 (A) to (I), and the guide member 33 configured as shown in FIGS. 28 (A) to (H). It is mounted on a substantially cylindrical cylinder case part 34 (see FIG. 7). Then, as shown in FIGS. 10 (A) and 10 (B), FIGS. 11 (A) and 11 (B), it is provided on the back surface of the cylinder lock 32 by a turning operation with the key 4 inserted into the cylinder lock 32. The position of the projection 32a is changed, and the restraining member 35 (see FIGS. 29A to 29C) having a groove 35a engaged with the projection 32a slides in the vertical direction in conjunction with the cylinder lock 32.

  Here, as shown in FIG. 7, the guide member 33 is fixed to the receiving plate 24 attached to the main body case 7 and does not move, whereas the cylinder lock 32 rotates to the cylinder case portion 34 of the guide member 33. The restraint member 35 is held by the guide member 33 so as to be slidable in the vertical direction. Therefore, a rail portion 35b is formed on the back surface of the restraining member 35, and a guide groove 33a for guiding the rail portion 35b is formed on the guide member 33. Further, the restraining member 35 is held by the guide member 33 so that the groove 35 a is positioned on the back side of the cylinder case portion 34.

  Then, as shown in FIG. 5A, in a state where the cylinder lock 32 is stopped at the locked position, the restraining member 35 is located at a restricting position for restricting the movement of the transmission member 12 (FIG. 10A, FIG. 11). At this time, as shown in FIGS. 13A and 13B, the locking claw 36a of the locking cam 36 provided in the locking member 35 is engaged with the locking groove 12a of the transmission member 12. The movement (slide) of the transmission member 12 is restricted (see also FIG. 7).

  Here, as shown in FIG. 7, the transmission member 12 has a locking wall 37 on the opposite side to the convex portion 30, and a locking groove 12 a is formed at the tip (front) end of the locking wall 37. ing.

  Further, the locking cam 36 is configured as shown in FIGS. 30A to 30D, and as shown in FIG. 7, as shown in FIG. As shown in FIG. 13A, the shaft 39 is moved by a spring 40 in a direction in which one end is brought into contact with the tip (front) end of the locking wall 37 of the transmission member 12 as shown in FIG. Get energized around.

  When the cylinder lock 32 is stopped at the lock position as described above, the rotation of the cylinder lock 32 is changed to the state where the cylinder lock 32 is stopped at the open position as shown in FIG. The restraining member 35 moves to a release position where the movement of the transmission member 12 is not restricted (see FIGS. 10B and 11B). At this time, as the restraining member 35 leaves the restriction position, the locking cam 36 is moved. Is guided forward along the inclined surface 41a of the guide wall 41 of the guide member 33 and moves forward, and the locking claw 36a moves forward from the locking groove 12a of the transmission member 12 against the bias of the spring 40. The transmission member 12 that is released and unlocked by the locking claw 36a is not regulated (see FIGS. 12A and 12B), and can be slid in the vertical direction. At this time, as shown in FIG. 12A, the locking cam 36 is locked to the mounting portion 41b (or the slope portion 41a) connected to the slope portion 41a of the guide wall 41 of the guide member 33 and transmitted. The member 12 is separated from the locking wall 37 of the member 12.

  By the way, when the operation of moving the cylinder lock 32 stopped in the open position to the lock position is performed (when the lock operation is performed using the key 4), the locking member 8 has the locking posture shown in FIG. In this case, while the restraining member 35 moves from the release position (see FIG. 11 (B)) to the restricting position (see FIG. 11 (A)), the transmission member 12 near the restricting position hardly moves. The locking claw 36a of the locking cam 36 of the restraining member 35 is locked with the locking groove 12a of the transmission member 12, whereby the locking operation is completed.

  On the other hand, when the locking member 8 is in the unlocking position shown in FIG. 4A, the transmission member 12 is positioned between the release position and the restriction position, and therefore the restraining member 35 is in the release position. The locking claw 36a of the locking cam 36 is locked in the locking groove 12a of the transmission member 12 at a midway position from when the locking member 36 is moved to the restricting position. Slides together and stops at the restriction position. With this slide, the locking member 8 changes from the unlocked posture to the locked posture. That is, when the restraining member 35 moves from the release position to the restricting position when the locking member 8 is in the unlocking posture, the restraining member 35 moves while being locked to the transmission member 12 via the locking cam 36. Then, the transmission member 12 is moved to cause the locking member 8 to take the locking posture.

  Therefore, when the locking is performed using the key 4, the locking member 8 can be locked in one action as it is even in the unlocked state as well as in the locked state.

  Further, when the unlocking is performed using the key 4, the restraining member 35 moves from the restricting position to the releasing position. At the start of this movement, the catching claw 36 a of the catching cam 36 locks the transmission member 12. Since it is in a state of being locked in the groove 12a, the transmission member 12 also moves together with the restraining member 35, and the locking member 8 changes from the locked posture to the unlocked posture with this movement. After this change, the locking claw 36a of the locking cam 36 guided by the inclined surface 41a of the guide wall 41 of the guide member 33 comes out of the locking groove 12a of the transmission member 12, so that the transmission member 12 is at that time. On the other hand, the restraining member 35 continues to move and reaches the release position.

  Therefore, when the main unlocking is performed using the key 4, the locking member 8 is automatically unlocked. Therefore, when opening the sliding door to which the lock in the present locking state is attached, in addition to the present unlocking operation, There is no need to separately perform temporary unlocking operation, and temporary unlocking can be performed with one action.

  Finally, (3) the unlocking operation with the push button 6 (temporary unlocking operation or temporary unlocking and permanent unlocking operation) refers to a forward pushing operation with respect to the push button 6, and this operation takes the locking posture. The locking member 8 is in the unlocked posture.

  The mechanism for realizing the operation (3) will be described with reference to FIG. 9. The movement of the push button 6 that receives the forward push operation is a vertical axis around the base 42 of the push button 6. It is converted into a rotating motion around. Along with this, a forward projecting portion 43 provided at the upper front portion of the push button 6 moves forward and comes into contact with the locking button 1, and this contact is the rotation around the rotary shaft portion 10 of the seesaw member 3. As a result of the movement, the locking button 1 moves forward and the unlocking button 2 moves backward. Such rotation of the seesaw member 3 is transmitted to the locking member 8 via the transmission member 12, and the locking member 8 which has taken the locking posture changes to a state of taking the unlocking posture. In addition, since the process in which the rotational motion of the seesaw member 3 is transmitted to the locking member 8 via the transmission member 12 has already been described in the description of the operation (1), the description thereof is omitted.

  Here, the push button 6 is configured as shown in FIGS. 31A to 31E. As shown in FIG. 7, the two base portions 42 of the push button 6 are through holes provided in the respective base portions 42. The push member 6 is connected to the guide member 33 by a pin member 44 inserted into the terminal 42 a, and the connected push button 6 can be rotated around the two pin members 44. Further, the push button 6 is biased by the spring member (not shown) wound around the one pin member 44 so as to rotate in the direction in which the protruding portion 43 (tip) moves forward around the pin member 44. As shown in FIGS. 31 (A), (C), (D), and (E), the push button 6 is formed with a hole 6a for inserting one end of the spring member. . The urging force that the push button 6 receives from the spring member is smaller than the urging force that the locking cam 36 receives from the spring 40.

  Accordingly, when the locking member 8 assumes the locking posture and the locking button 1 is in the retracted position, the push button 6 disposed on the back side of the seesaw member 3 is subjected to a forward pushing operation as shown in FIG. Then, the push button 6 rotates around the pin member 44, and the protrusion 43 of the push button 6 abuts against the edge of the lock button 1 to advance the lock button 1, and the lock member 8 is unlocked accordingly. You will take a locked posture.

  The unlocking operation by the push button 6 can be performed in either the temporary locking state or the main locking state. That is, if the unlocking operation is performed with the push button 6 in the temporary locking state, the operation is performed as described above. Further, when the unlocking operation by the push button 6 is performed in the locked state, in addition to the above-described operation, the release cam 45 interlocked with the push button 6 comes into contact with the locking cam 36 to lock the transmission member 12. An operation for releasing the lock of the cam 36 for the main unlocking also proceeds at the same time.

  Specifically, as shown in FIG. 7, a release cam 45 is connected to one of the two base portions 42 of the push button 6. As shown in FIGS. 30B and 30D, the locking cam 36 has a locked claw 36b on the opposite side of the locking claw 36a.

  Here, when the lock using the key 4 is not performed, the cylinder lock 32 is in the open position, and the restraining member 35 is in the release position as shown in FIG. It does not contact the locked claw 36b of the locking cam 36 or contacts the locking cam 36 to such an extent that the locked claw 36b is hardly pressed. In FIG. 10B, although it appears that the release cam 45 and the claw 36b are overlapped, the back surface of the release cam 45 has an obliquely cut shape (see FIG. 7). In fact, both 45 and 36b are not in contact.

  Then, the lock using the key 4 is performed so that the cylinder lock 32 moves to the lock position, and when the restraining member 35 moves to the restriction position as shown in FIG. 10A, the release cam 45 is locked. It will be in the state which contacts the front surface of the nail | claw 36b. However, in this state, the release cam 45 does not press the to-be-latched claw 36b to rotate the locking cam 36.

  When the push button 6 is pushed forward in the above state, the push button 6 rotates around the pin member 44, and a release cam 45 provided on the push button 6 and rotated integrally with the push button 6 is provided. By pressing the locked claw 36b, the locking claw 36a of the locking cam 36 is removed from the locking groove 12a of the transmission member 12 (see FIGS. 14A and 14B). Therefore, in this state, the transmission member 12 can be slid in the vertical direction, and the lock button 1 in the retracted position is moved forward by the further rotation of the push button 6, and the seesaw member 3 is moved to the rotary shaft portion 10. This rotation is transmitted to the locking member 8 via the transmission member 12, and the locking member 8 changes from the locked posture to the unlocked posture.

  The above is the operation for performing the actual unlocking at the time of the unlocking operation by the push button 6, and after this operation, as shown in FIGS. 15A and 15B, the locking claw 36a of the locking cam 36 is The locking member 35 is locked to the locking wall 37 of the transmission member 12, and the restraining member 35 is stopped at the restricting position. Thus, in such a state, the key 4 may be inserted into the cylinder lock 32 and rotated to return the restraining member 35 to the release position.

  By the way, when the locking member 8 is in the locking posture, the locking button 1 is in the retracted position, and when the push button 6 is pushed forward at this time, the protruding portion 43 of the push button 6 comes into contact with the locking button 1. As described above, when the locking member 8 is in the unlocked position, the locking button 1 is in the forward movement position. At this time, even if the push button 6 is pushed forward, The unlocked state is maintained without contact.

  Therefore, even when a person is confined in the storage room in which the lock of the present embodiment is attached to the sliding door, the person only performs the unlocking operation by pushing the push button 6 forward from the inside of the cabinet (inside the storage room). Since this unlocking operation is very simple, it is easy to escape from the storage room even if it is dark. Further, the operation on the push button 6 is only the unlocking operation by the pushing operation, and the locking operation is not performed from the inside of the warehouse, so that the person trapped in the storeroom panics and the unlocking operation and the locking operation are performed. There is no such thing as repeating.

  Further, as shown in FIG. 19A, an opening 46 is formed in the center of the seesaw body 3A, which is closed by a transparent plate material, for example, not shown, and the push button 6 on the back side of the seesaw body 3A is It is formed of a transparent material. Therefore, in the lock of the present embodiment, lighting from the opening 46 of the seesaw body 3A into the storage is possible, and the back side of the opening 46 of the seesaw body 3A has an arrow shape made of a phosphorescent material. Since the display member 47 (see FIGS. 1A and 31A) is arranged, even if a person is confined in the storeroom, the person can receive light or light introduced into the storeroom from the opening 46. The push button 6 can be easily found by relying on the light emitted by the display member 47. 3 to 5, the illustration of the opening 46 is omitted.

  Further, in order to prevent the unlocking button 2 from being unlocked when the unlocking button 2 is pressed with a strong force in the locked state as shown in FIGS. In the embodiment, a stopper 48 configured as shown in FIGS. 32A to 32D is provided.

  More specifically, as shown in FIG. 7, the stopper 48 is formed with two through holes 48a and 48b, one of the through holes 48a is penetrated by the pin member 44, and the other through hole 48b has a release cam 45. The protrusion 42b provided on the base 42 that is not continuously provided is inserted. Therefore, the stopper 48 rotates around the pin member 44 integrally with the push button 6 and interlocks with the release cam 45.

  By the way, as the cylinder lock 32 moves from the open position to the locked position, the release cam 45 abuts on the locked claw 36b of the locking cam 36 as shown in FIG. However, at this time, as shown in FIG. 16, the stopper 48 interlocked with the release cam 45 is stopped at a position where the unlocking button 2 in the forward movement position is prevented from moving backward, The backward push operation to the unlock button 2 becomes impossible. Therefore, even when the unlock button 2 is pressed with a strong force in this locked state, it is not unlocked. In addition, when the lock is not fully locked and is in a temporary lock state, as shown in FIGS. 3A and 3B, the unlock button 2 is in the forward position, but to the rear with respect to the unlock button 2 in this state. Therefore, the stopper 48 does not hinder the pushing operation. Therefore, as shown in FIG. 6, the seesaw body 3A and the lock display plate 3C are provided with recesses 49 and 50 corresponding to the stopper 48, respectively.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

  In the said embodiment, as shown in FIG. 6, although the unlocking display board 3B and the locking display board 3C are made into the separate body with respect to 3 A of seesaw main-body parts, it is not restricted to this, For example, these three members 3A-3C In this case, the portions corresponding to the unlocking display board 3B and the locking display board 3C in the seesaw member 3 may be painted in blue and red, respectively.

  In the above embodiment, when the locking button 1 or the unlocking button 2 is pushed in the unlocked state, the rotational motion of the seesaw member 3 is converted into the linear motion of the transmission member 12, as shown in FIG. Although this linear motion is converted into the rotational motion of the locking member 8, such a force transmission mechanism can be variously modified. For example, the mechanism shown in FIG. It may be changed to a pinion mechanism or the like, and this also applies to other force transmission mechanisms.

  That is, for example, in the above-described embodiment, as shown in FIG. 9, the protruding portion 43 that protrudes forward is provided on the front surface of the push button 6. You may make it provide the protrusion part which protrudes back in 1 back surface. Moreover, although the push button 6 and the locking button 1 may contact | abut directly, you may make it contact | abut via another member.

  In the example shown in FIGS. 6 and 7, the spring member 51 for giving a sense of moderation to the rotation of the locking member 8 via the claw member 28 is attached to the guide member 33. A spring member 51 may be attached to the receiving plate 24.

  Needless to say, the above modifications may be combined as appropriate.
