Description

  The present invention relates to a push-pull electric lock that is unlocked by a push-pull operation in the same direction as the door opening direction, and in particular, it reduces the required space in the lock bolt advance / retreat direction and locks or unlocks by remote control by electric control. The present invention relates to an improved technology that enables a lock.

  Some locking devices include a latch (latch bolt) that keeps the door closed without being locked. The latch bolt has an inclined surface at the tip and is urged in the direction protruding from the door mouth. By closing the door, the latch bolt comes into contact with the edge of the strike plate provided on the opening frame side, After retreating inward, the door is kept closed by projecting into the swaying plate. Latch bolts are generally retracted by operating the operating members (lever handle, knob, etc.) provided on the front and back of the door by an advancing / retracting mechanism provided integrally with the lock case, and the closed state is released when the latch bolt is removed from the inside of the trolley. To do.

  By the way, a so-called push-pull lock in which an end of a long operation bar is movably attached to a door surface via a pedestal may be adopted for an entrance door such as a house or an office building. For example, when the push-pull lock is attached to an exterior door, the operation bar on the indoor side moves in the pushing direction, and the operation bar attached on the outdoor side moves in the pulling direction to lock the lock bolt. Retract into the case to open the door. Thereby, in the door front and back, the door opening direction and the bar operation direction are made to coincide with each other, thereby realizing good operability of the door.

  In recent years, glass doors have been frequently used due to the strength improvement of glass materials. When this type of glass door is provided with a locking device, it is common to attach a metal frame portion to the glass and to provide a locking device on the vertical frame of the door opening / closing end. When the latch bolt is provided in the lock device accommodated in the vertical frame of such a glass door, in the double door, the inclined surface is brought into contact with the strike plate provided in the vertical frame of the mating member (mating side glass door). Will be allowed to. Further, in the single opening, the inclined surface comes into contact with the strike plate provided on the counterpart member (opening frame).

However, in particular, in the case of a lock device provided on the glass door, it is desirable to use a latch bolt mechanism that does not allow the inclined surface to come into contact in order not to generate a reaction force at the time of contact. Further, in the glass door in which the operation bar of the push-pull lock is attached to the vertical frame, it is desirable that the vertical frame that accommodates the locking device is as narrow and narrow as possible in order not to deteriorate the design. Furthermore, in order to achieve space saving, it is more preferable that a latch bolt as a latch and a dead bolt for locking function by using only a single locking bolt. For these reasons, the push-pull lock provided on the glass door does not use the reaction force caused by the contact with the mating member, has a dead bolt function, and minimizes the depth of the lock case in the advancing and retracting direction of the latch bolt. It was necessary to limit.
In addition, with the push-pull lock, there is a market demand for an electric lock that can be locked or unlocked by remote control by electric control along with the improvement of convenience and the introduction of a security system. Furthermore, when an electric lock is used, it is more preferable in terms of manufacturing cost reduction that a single product can cope with various electric control variations.

  The push-pull electric lock according to claim 8 is characterized in that a ratchet claw 105 for holding the slide cam plate 31 is connected to the releaser 95 so that the lock bolts 25 are sequentially moved to the retracted position.

  In this push-pull electric lock, the slide cam plate 31 is sequentially held by the ratchet pawl 105 in the ascending slide process until the slide cam plate 31 is held by the latch body 79 at the upper end movement position. An electromagnet is used as the magnetism generating means on the side of the locked body that applies a magnetic repulsive force to the releaser 95. When the electromagnet is opened, an electric signal for generating magnetism is applied to the electromagnet. Simultaneously with the closing of the door, the releaser 95 is swung by the magnetic repulsive force of the electromagnet, the holding by the latch body 79 is released, and the slide cam plate 31 slides, whereby the lock bolt 25 is protruded. Thereafter, the door closing state is detected by the door closing detecting means, and the magnetically generated electric signal to the electromagnet is cut off. That is, the releaser 95 assumes a posture before swinging because the magnetic repulsive force is not applied. Thus, when the door is closed, the slide cam plate 31 can be held by the latch body 79 and the slide cam plate 31 can be held by the ratchet pawl 105.

  According to the push-pull electric lock according to claim 1 of the present invention, the lock bolt protruding in the horizontal direction from the vertical frame is actuated by the slide cam plate sliding in the longitudinal direction of the vertical frame, and the locked body is closed by the door. The releaser that receives the magnetic repulsive force from the latch releases the holding of the slide cam plate by the latch body, that is, the lock bolt is retracted, so it can be installed in a narrow space such as the vertical frame of the door and at the same time as the door is closed Automatic door-holding that allows the lock bolt to protrude can be realized. In addition to this, an electromagnetic plunger to which an electric signal is applied, a drive connector that is directly moved by the plunger, a distal end engaging portion is connected to the rocking proximal end of the lock claw, and a proximal end connecting portion is connected to the drive connector. Therefore, the lock claw can be electrically controlled, and the lock claw can be locked or unlocked with the operation shaft locked or unlocked by remote control.

  According to the push-pull electric lock according to claim 2, the depth length of the lock case in the lock bolt advance / retreat direction and the total length of the lock bolt in the advance / retreat direction are formed substantially equal, and the rear end of the lock bolt is formed in the thickness direction. Since the slide cam plate is arranged in the bisecting slit, the slide cam plate does not protrude in the lock bolt retreat direction, and the depth length of the lock case in the lock bolt advance / retreat direction can be made the minimum length that is the same as the total length of the lock bolt. . In addition, since the lock bolt and slide cam plate can be engaged at the center in the thickness direction, the lock bolt and slide cam plate do not generate a moment around the axis in the lock bolt advance / retreat direction, and the lock bolt and slide cam plate can be smoothly moved. Can be operated.

  According to the push-pull electric lock according to claim 3, a vertical slide hole is formed in the drive connector, a square guide hole is formed in the proximal end connecting portion of the switching cam, and a slide pin is formed in the vertical slide hole and the square guide hole. The slide piece that slidably penetrated and held the slide pin was slidably exposed on the front back plate, so by sliding the slide piece, the position of the switching cam relative to the drive connector was displaced, and The direct movement of the plunger can be switched to lock or unlock of the lock claw. That is, a slide piece is provided so that an electric control variation can be set according to the situation. As a result, a single kind of push-pull electric lock can be set to different electric control contents depending on the application, and versatility can be improved.

  According to the push-pull electric lock according to claim 4, since the slide piece is covered by the front plate attached to the back plate, the slide piece is not exposed by being covered by the front plate when the door is normally opened and closed. It is possible to prevent malfunctions caused by the mischief of the pieces.

As a result, it is possible to set a confusion prevention mode (anti-panic mode) that prevents confusion (panic) due to the inability to open the door in an emergency or emergency such as a disaster.

  According to the push-pull electric lock of the sixth aspect, the slide cam plate is sandwiched, and the operation shaft, the lock claw, the switching cam, and the slide piece are disposed in pairs, and these components operate on the front and back sides of the door, respectively. In addition, the operation shaft can be independently operated on the front and back sides of the door to operate the dual-purpose parts such as the slide cam plate, and locking and unlocking by remote operation can be independently performed on the front and back of the door. Further, since the rotation of one operation shaft is not transmitted to the other operation shaft, unnecessary movement of the non-operation side operation bar can be eliminated.

  According to the push-pull electric lock of the seventh aspect, since the vertical hole is extended at the upper end of the oblique hole of the slide cam plate, the lock bolt is attached to the upper end of the oblique hole by the slide of the slide cam plate in accordance with the projecting operation. When the engaging portion reaches, the retraction of the protruding lock bolt is prevented by the engaging portion that hits the vertical hole. As a result, the lock bolt can be retracted with high strength with a simple structure.

  According to the push-pull electric lock according to claim 8, the ratchet pawl for holding the slide cam plate is connected to the releaser so that the lock bolt is sequentially moved to the retracted position. In the ascending process until it is held, the slide cam plate can be held in order. As a result, when the lock bolt is retracted, a click feeling due to the sequential engagement of the ratchet claws is generated, and the operation feeling can be improved.

DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a push-pull electric lock according to the present invention will be described in detail with reference to the drawings.

A spring 107 is provided between the ratchet pawl 105 and the front back plate 39, and the spring 107 biases the ratchet pawl 105 rightward in FIG. A rack 109 facing the ratchet pawl 105 is formed on the upper front edge of the slide cam plate 31.

  The ratchet pawl 105 is urged by the spring 107, and holds the slide cam plate 31 so that the lock bolt 25 is sequentially moved to the retracted position. Therefore, the slide cam plate 31 can be sequentially held in the ascending process until the slide cam plate 31 is held by the latch body 79 at the upper end movement position. As a result, when the lock bolt is retracted, the ratchet pawl 105 is sequentially meshed so that a click feeling is generated, and a good operation feeling can be obtained.

  The releaser 95 is provided with a support hole 111 through which the support shaft 110 passes in the center. A connection hole 113 through which a rotation pin 97 for connecting to the latch lock plate 85 is inserted is formed in the lower part of the releaser 95. A magnet 115 is attached to the upper part of the releaser 95, and the magnet 115 coincides with the magnet exposing opening hole 47 of the front back plate 39. The releaser 95 rotates in the clockwise direction and is restricted by the stopper pin 116 as shown in FIG. 10 by receiving a repulsive force from an electromagnet provided on a mating member (such as a mating glass door or an opening frame). The The released releaser 95 moves the latch lock plate 85 to the left in the figure, and as a result, the rotation restriction of the latch body 79 is released as shown in FIG. In other words, the door is actuated by receiving a magnetic repulsive force from the locked body at the closed door, and the holding of the latch body 79 to the slide cam plate 31 is released.

  The electromagnet is applied with an electric signal for generating magnetism when the door is opened. Simultaneously with the closing of the door, the releaser 95 is swung by the magnetic repulsive force of the electromagnet, the holding by the latch body 79 is released, and the slide cam plate 31 slides, whereby the lock bolt 25 is protruded. Thereafter, the door closing state is detected by the door closing detecting means, and the magnetically generated electric signal to the electromagnet is cut off. That is, the releaser 95 assumes a posture before swinging because the magnetic repulsive force is not applied. Thus, when the door is closed, the slide cam plate 31 can be held by the latch body 79 and the slide cam plate 31 can be held by the ratchet pawl 105.

  The push-pull electric lock 100 is a resin in which at least sliding parts such as a lock bolt 25 and a slide cam plate 31 and at least swing parts such as a lock claw 63 and a ratchet claw 105 are disposed in a gap with the lock case 19. The position of the spacer member 184 is slidably contacted with the spacer member 184 (see FIG. 6A), and the operation is guided. As described above, the sliding parts and the swinging parts are slidably brought into contact with the resin spacer member 184, and the position is maintained and the movement is guided. Can increase the sex. In addition, wear between metals can be reduced and durability can be improved.

  Further, the push-pull electric lock 100 has a slide cam plate 31 sandwiched therebetween, and a pair of operation shafts 55 and lock claws 63 are disposed, and these components operate on the front and back sides of the door 11, respectively. That is, the operation shaft 55 (that is, the operation bars 21 and 23) can be operated independently on the front and back sides of the door. Further, the rotation of one operation shaft 55 is not transmitted to the other operation shaft 55. Thereby, the operation shaft 55 can be independently operated on the front and back sides of the door, and the combined parts such as the slide cam plate 31 can be operated. Further, the rotation of one operation shaft 55 is not transmitted to the other operation shaft 55, and unnecessary movement of the non-operation side operation bar is prevented.

Next, the latch operation of the push-pull electric lock 100 having the above configuration will be described.
In the push-pull electric lock 100, when the outdoor operation bar 21 or the indoor operation bar 23 is operated in a state where the lock bolt 25 protrudes (the state shown in FIG. 2), and the operation shaft 55 is rotated via the conversion mechanism 65, As shown in FIG. 7, the slide cam plate 31 is pushed up by the pressing plate portion 59.

  When the slide cam plate 31 moves upward, the ratchet pawl 105 is sequentially engaged with the rack 109, and the lock bolt 25 is sequentially held at the retracted position. When the upper edge of the slide cam plate 31 reaches the latch body 79, the latch body 79 is pushed to the left side in FIG. 11 against the urging force of the coil spring 91 as shown in FIG. When the slide cam plate 31 is further moved and the locking hole 81 is aligned with the latch body 79, the latch body 79 protrudes due to the urging force of the coil spring 91, and the locking hole 81 is locked into the locking hole 81 as shown in FIG. Then, the slide cam plate 31 is held at the upper end movement position.

  The glass door 11 is opened in this state, that is, in a state where the lock bolt 25 shown in FIG. 9 is retracted. In this state, even if the outdoor operation bar 21 and the indoor operation bar 23 are operated, only the operation shaft 55 rotates, and the pressing plate portion 59 may interfere with the slide cam plate 31 disposed at the upper end movement position. Absent.

  On the other hand, in order to operate the lock bolt 25 as a latch (latch bolt), an electric signal that generates repulsive force is applied to the electromagnet of the mating member facing the magnet 115 of the releaser 95. Thus, when the glass door 11 is closed, the magnet 115 of the releaser 95 moves away as shown in FIG. 10, and as a result, the latch lock plate 85 is moved to the left in FIG.

  When the latch lock plate 85 is moved, as shown in FIG. 11D, the pressure on the receiving seat 83 by the rotation restricting surface 87 is released, and the latch body 79 can rotate about the shaft 79a. As a result, the latch body 79 is rotated clockwise in FIG. 11 by the slide cam plate 31 pulled downward by the urging force of the tension spring 61, the latch is released, and the slide cam plate 31 is lowered.

  When the slide cam plate 31 descends, the lock bolt 25 protrudes again through the engaging means 33 and engages with the mating member. When the outdoor operation bar 21 and the indoor operation bar 23 are operated in the closed state of the glass door 11, the slide cam plate 31 is pushed up again through the operation shaft 55 and the pressing plate portion 59, and the lock bolt 25 is retracted. By doing so, the door can be opened.

  As described above, in the push-pull electric lock 100, the slide cam plate 31 for converting the rotation of the operation shaft 55 into the retreat / advance movement of the lock bolt 25 is movable in the direction orthogonal to the advance / retreat direction of the lock bolt 25. Be placed. Thereby, it is not necessary to arrange mechanical parts in the lock bolt retracting direction of the lock case 19 or to secure an operation space.

  Therefore, according to the above configuration, the slide cam plate 31 provided in the lock case 19 so as to be reciprocally movable along the vertical frame 17 and the lock bolt provided in the lock case 19 so as to advance and retreat from the door opening / closing end surface 11c. 25, a pressing plate portion 59 formed on the operation shaft 55 to push up the slide cam plate 31, engagement means 33 for converting the vertical movement of the slide cam plate 31 into the backward movement and advancement of the lock bolt 25, and the slide cam plate 31. Since the latch body 79 that holds the slide cam plate 31 at the upper end movement position is provided, the slide cam plate 31 for converting the rotation of the operation shaft 55 into the retreat / advance movement of the lock bolt 25 is provided on the lock bolt 25. It can be arranged so as to be movable in a direction perpendicular to the advancing / retreating direction, and there is no need to arrange a conversion member in the retreating direction of the lock bolt of the lock case 19 or to secure an operating space.

  That is, the depth length D of the lock case 19 in the lock bolt advance / retreat direction can be minimized. As a result, the push-pull electric lock 100 can be accommodated in the vertical frame 17 having a small width without using the reaction force caused by the collision with the mating member. Can be improved.

  By the way, the push-pull electric lock 100 can be locked or unlocked by remote control by electric control in accordance with convenience improvement and security system introduction. Moreover, when the push-pull electric lock 100 is such an electric lock, it is more preferable in terms of manufacturing cost reduction that a single product can cope with various electric control variations. From such a request, the push-pull electric lock 100 further has the following configuration.

FIG. 12 is an exploded perspective view of the electric lock portion, and FIG. 13 is an enlarged side view of the electric lock portion in which the slide piece is arranged in the R mode when the plunger is not operated (a), and when the plunger is operated (b). FIG. 14 is an enlarged side view of the electric lock portion in which the slide piece is disposed in the A mode when the plunger is not operated (a), and when the plunger is operated (b). The electric lock portion in which the slide piece is disposed in the T mode will be described with reference to FIGS.
As shown in FIG. 5, a solenoid 143 of an electromagnetic plunger 144 is fixed in the lock case 19 below the lock claw 63, and the solenoid 143 is excited by the application of an electric signal from the outside to advance and retract the lock bolt 25. Directly move the plunger 145 in the direction. The drive connector 147 is coupled to the plunger 145, and the drive connector 147 is slid in the linear movement direction of the plunger 145 (the direction of arrow b in FIG. 6). The electromagnetic plunger 144 and the drive connector 147 are a single part that is also used on the front and back of the door.

  As shown in FIG. 12, the drive connector 147 is formed with a connection recess 149, and the connection recess 149 is engaged with the tip step portion 145 a of the plunger 145. In the drive connector 147, a connection block portion 147a in which a connection recess 149 is formed is movably disposed in the movable space 155 (see FIGS. 5 and 6) of the lock case 19. A return compression spring 151 is inserted between the solenoid 143 and the connection block portion 147a, and the return compression spring 151 biases the connection block portion 147a to the left in FIG. When the solenoid 143 is energized, the plunger 145 moves to the right in the figure against the urging force of the return compression spring 151. As a result, a gap S shown in FIG. 6B is formed in the movable space 155 and the connecting block portion 147a.

  A switching cam 159 shown in FIG. 12 is swingably supported at a lower portion of the lock case 19 by a support shaft 157 (see FIG. 5) which is a rotation center in the same direction as the operation shaft 55. A pair of the switching cams 159 is provided on the front and back of the door with the drive connector 147 interposed therebetween. A connecting claw 161 is formed at the tip engaging portion 159 a of the switching cam 159, and the connecting claw 161 holds the connecting pin 63 b of the lock claw 63. Thereby, the switching cam 159 is connected to the rocking base end (the connecting pin 63b) of the lock claw 63.

  As shown in FIG. 12, the drive connector 147 is formed with a vertical slide hole 167 that is long in the longitudinal direction of the vertical frame 17. The base end connecting portion 159 b of the switching cam 159 is formed with a rectangular guide hole 169 that overlaps with the vertical slide hole 167 and whose central portion is close to the support shaft 157. A slide pin 171 is slidably penetrated through the vertical slide hole 167 and the rectangular guide hole 169. As a result, the base end connecting portion 159 b of the switching cam 159 is connected to the drive connector 147 via the slide pin 171.

  The slide pin 171 is fixed to the small piece 175 with a caulking pin 173. The small piece 175 is accommodated in the recess 179 of the slide piece 177 so as to be movable in the lateral direction. The small piece 175 is urged to the left in FIG. 12 by the helical spring 180 to prevent rattling. The slide piece 177 holding the slide pin 171 via the small piece 175 is slidably exposed on the front back plate 39 of the lock case 19. The slide piece 177 is guided by a guide groove 39a (see FIG. 5) formed in the front back plate 39. A pair of slide pieces 177 and small pieces 175 are provided on the front and back of the door with the drive connector 147 interposed therebetween.

  The electric lock portion 179 is configured with the electromagnetic plunger 144, the drive connector 147, the switching cam 159, the slide pin 171, and the slide piece 177 as main members. As will be described later, the electric lock 179 applies an electric signal to the solenoid 143 to directly move the single drive connector 147 via the plunger 145 and swing the paired switching cams 159 and 159. By moving, the front and back lock claws 63 can be operated remotely.

  Further, by sliding the front and back slide pieces 177, the position of the switching cam 159 relative to the drive connector 147 is changed to the energization unlocking mode (T mode) shown in FIG. 6 and the energization locking mode (R mode) shown in FIG. ), And is displaced to the position of the anti-panic mode (A mode) shown in FIG. 14 so that the direct movement of the plunger 145 can be switched between locking and unlocking of the lock claw 63.

  6 (a), 13 (a), and 14 (a) all show a non-energized state. That is, when the power is not supplied, the T mode is locked, the R mode is unlocked, and the A mode is unlocked. In FIG. 6, reference numeral 181 denotes a positioning protrusion protruding from the slide piece 177, and reference numerals 183T, 183R, and 183A denote positioning recesses formed in the resin spacer member 184. The slide piece 177 is held at each mode position by elastically contacting the positioning protrusion 181 with the upper, middle, and lower positioning recesses 183T, 183R, and 183A.

  The width of the vertical slide hole 167 and the width of the rectangular guide hole 169 substantially coincide with the outer diameter of the slide pin 171. The square guide hole 169 is bent into a square shape. Therefore, if the slide pin 171 is moved in the vertical direction along the vertical slide hole 167, the switching cam 159 is oscillated and displaced with respect to the drive connector 147 by the amount of bending of the rectangular guide hole 169. . That is, the relative angle between the two changes. By this displacement, the position of the connecting claw 161 with respect to the connecting pin 63b of the lock claw 63 is changed, and the locking arrangement (for example, see FIG. 6A) and the unlocking arrangement (for example, see FIG. 13A) of the lock claw 63 are variably set. It is possible.

  In the lock case 19, the front back plate 39 is covered with the front plate 41. Therefore, the slide piece 177 exposed on the front back plate 39 is covered and hidden by the front plate 41. As a result, when the door 11 is normally opened and closed, the slide piece 177 is not exposed because it is covered with the front plate 41, and malfunction due to the slide piece 177 being mischievous can be prevented. In addition, switching work during maintenance is possible.

  Further, in the vertical slide hole 167 of the drive connector 147, a widened portion 185 shown in FIG. 12 corresponding to the amount of linear movement of the plunger 145 is formed. By arranging the slide pin 171 in the widened portion 185, even if the drive connector 147 moves due to the direct movement of the plunger 145, the movement of the drive connector 147 is not transmitted to the slide pin 171 and the operation of the electromagnetic plunger 144, Regardless of non-operation, the anti-panic mode (A mode) in which the operation shaft 55 is always in the unlocked state can be set. As a result, it is possible to prevent confusion (panic) due to the inability to open the door in an emergency or emergency such as a disaster.

Next, each operation of the push-pull electric lock 100 in the T mode, the R mode, and the A mode will be described. The operations of the slide cam plate 31, the latch body 79, the ratchet pawl 105, the releaser 95, and the like are the same as described above, and will not be described.
First, in the T mode in which the lock claw 63 is unlocked when energized, as shown in FIG. 6A, when the door is not energized, the plunger 145 is protruded and the drive connector 147 is disposed on the left side. . Since the switching cam 159 is rotationally arranged counterclockwise by the slide pin 171, the connection pin 63 b is pulled by the connection claw 161, and as a result, the lock claw 63 is urged counterclockwise to operate the operating shaft. 55 is locked. That is, it becomes a locked state.

  On the other hand, as shown in FIG. 6B, when an electrical signal is applied to the electromagnetic plunger 144, the plunger 145 is pulled rightward and the drive connector 147 is moved in the same direction. When the drive connector 147 is moved to the right, the slide pin 171 located above the support shaft 157 is moved to the right, and the connection claw 161 pushes the connection pin 63b to the right. As a result, the lock claw 63 rotates clockwise and the lock on the operation shaft 55 is released.

  When the operation shaft 55 is rotated in this state, as shown in FIG. 7, the slide cam plate 31 is pushed up, the lock bolt 25 is retracted, is retracted and held by the latch body 79, and the door can be freely opened.

  Further, in the R mode in which the lock claw 63 is locked when energized, as shown in FIG. 14B, when energized in the closed state, the plunger 145 is pulled rightward, and the switching cam 159 is counterclockwise by the slide pin 171. Rotating around. The connection pin 63 b is pulled by the connection claw 161, and as a result, the lock claw 63 is locked to the operation shaft 55. That is, it becomes a locked state.

  On the other hand, if the door is not energized, as shown in FIG. 13A, the plunger 145 is in the protruding position, and the drive connector 147 is moved and arranged in the same direction. When the drive connector 147 is moved to the left, the slide pin 171 located below the support shaft 157 is moved to the left, and the connection claw 161 pushes the connection pin 63b to the right. As a result, the lock claw 63 rotates clockwise and the lock on the operation shaft 55 is released.

  When the operating shaft 55 is rotated in this state, the slide cam plate 31 is pushed up, the lock bolt 25 is retracted, and is retracted and held by the latch body 79.

  As shown in FIG. 14, when the slide piece 177 is disposed at the lowest A mode position, the slide pin 171 is disposed at the lower end of the vertical slide hole 167 and the rectangular guide hole 169. When the electromagnetic plunger 144 is not energized, as shown in FIG. 14A, the switching cam 159 remains rotated at the clockwise position, the connecting claw 161 pushes the connecting pin 63b to the right, and the locking claw 63 Is urged clockwise and the operation shaft 55 is unlocked.

  Further, as shown in FIG. 14B, even when an electric signal is applied to the electromagnetic plunger 144 and the drive connector 147 moves to the right, the slide pin 171 has the widened portion 185 of the vertical slide hole 167 (see FIG. 12). ), The slide pin 171 remains in the same position, and the switching cam 159 does not rotate counterclockwise. That is, the operation shaft 55 is in the unlocked state regardless of energization / non-energization. However, for example, if the slide piece 177 arranged on the front surface 11a of the door 11 is in the A mode and the slide piece 177 arranged on the back surface 11b is other than the A mode, the back side mode is independent of the front surface 11a. It becomes effective.

FIG. 15 is a correlation diagram showing a non-energized state and a locked state when energized in each mode when the door is closed.
Thus, in the setting of the T mode, the push-pull electric lock 100 is in a locked state when not energized, and is in an unlocked state when energized.
When the R mode is set, the lock is released when no power is supplied, and the lock is set when the power is supplied.
In the setting of the A mode, the lock is always released regardless of whether the power is off or on.

  The push-pull electric lock 100 is provided with the electric lock portion 179 so that it can be operated remotely, and is locked from the outside or unlocked from the outside (no key is required for unlocking, for example, there is no key) Allow visitor permission). In addition, while the lock is enabled (locked when the door is closed), the door can be unlocked by opening the operation shaft 55 (outdoor operation bar 21, indoor operation bar 23), thereby causing a panic in an emergency or emergency. First, passage can be made possible regardless of the state of the lock, such as securing a slammed passage.

  Therefore, according to the push-pull electric lock 100 according to the present embodiment, in addition to the effects of the basic mechanism described above, the electromagnetic plunger 144 to which an electric signal is applied, the drive connector 147 that is directly moved by the plunger 145, and the tip engagement Since the joint portion 159a is connected to the rocking base end (connecting pin 63b) of the lock claw 63 and the base end connecting portion 159b is connected to the drive connector 147, the lock claw 63 is electrically controlled. And it can be locked or unlocked by remote control. As a result, it is possible to improve convenience and to easily cope with a security system or the like.

  Further, a vertical slide hole 167 is formed in the drive connector 147, a square guide hole 169 is formed in the proximal end connecting portion 159b of the switching cam 159, and the slide pin 171 can be freely slid into the vertical slide hole 167 and the square guide hole 169. Since the slide piece 177 having the slide pin 171 fixed thereto is slidably exposed on the front back plate 39 of the lock case 19, the slide piece 177 is slid to thereby change the switching cam 159 for the drive connector 147. Thus, the direct movement of the single plunger 145 can be switched between locking and unlocking of the lock claw 63. That is, the slide piece 177 is provided so that the electric control variation can be set according to the situation. As a result, the single-type push-pull electric lock 100 can be set to different electric control contents depending on the application, and versatility can be improved.

  Further, according to the push-pull electric lock 100, since the pair of switching cams 159 and the slide pieces 177 are disposed on the front and back sides of the door with the single drive connector 147 interposed therebetween, the slide position of each slide piece 177 on the front and back sides of the door can be changed. Then, the rectangular guide holes 169 of the respective switching cams 159 are displaced with respect to the single vertical slide hole 167 of the drive connector 147, and the lock claw 63 is disposed on the front and back of the door due to the difference in displacement. Can be variably set. As a result, various electric control variations can be set according to the application.

  The push-pull electric lock 100 can be locked so that the operation shaft 55 is non-rotatably locked (locked) by the lock claw 63 and prevents the lock bolt 25 from moving backward as described above. A cylinder lock or thumb turn locking / unlocking means may be provided. In this case, for example, cylinder locks to be added can be distributed in the longitudinal direction of the vertical frame 17 by being arranged on the upper part of the lock case 19. That is, it is not necessary to increase the width D of the depth of the lock case 19. A modification in which a cylinder lock as a locking / unlocking means is provided will be described with reference to FIGS.
