Description

  The present invention relates to an electric lock state detection mechanism that detects a locked state or an unlocked state of an electric lock that causes a dead bolt to advance and retract by an electric actuator.

  An electric lock that can be locked and unlocked by remote control may be provided on a hotel door or an entrance door of a condominium. In this type of electric lock, for example, an electric motor, which is an electric actuator, is installed in a lock box, and when the electric motor is rotated forward and backward (rotated) by a locking / unlocking control signal transmitted from a management room or a management device or the like. The rotation is transmitted to the Dharma shaft through the gear, and the dead bolt is moved back and forth by the rotation of the Dalma shaft. Here, in a management room, a management device, or the like, in order to confirm a locking / unlocking state or to obtain a trigger signal such as an electric motor stop control, a state in the locking / unlocking mechanism of the electric lock is detected.

  Conventionally, the state detection mechanism of this electric lock is installed in the lock box by applying a slide member for detection to a part of the gear interlocked with the electric motor, and reciprocating this slide member by forward and reverse rotation of the electric motor. By directly slidably contacting the convex portion of the slide member with the pressing member of the lock detection switch or the unlock detection switch, the switches are directly pressed by the reciprocation of the slide member. That is, when the electric motor is rotated in the locking direction, the slide member moves forward through the gear, and the convex portion or the like presses the locking detection switch, while when the electric motor is rotated in the unlocking direction, the gear is moved. Then, the slide member moved backward, and the convex portion or the like pressed the unlock detection switch.

  However, the state detection mechanism of the conventional electric lock reciprocates the slide member by forward and reverse rotation of the electric motor, and directly contacts the slide member with the pressing member of the lock detection switch or the unlock detection switch. Since the switch was directly pressed, there was a problem that the pressing stroke of the switch was required with high accuracy. In other words, the switch can be operated normally only within a short stroke range. For this reason, it is often the case that the switch is pressed too much or insufficiently pressed, that is, if the switch is pressed too much, damage will occur, and if the switch is pressed insufficiently, a malfunction that is impossible to detect will occur, improving the reliability of the state detection operation. There was a request.

Thereby, it can be made to operate optimally so that the pusher of the switch in the state detection mechanism of the electric lock is not pushed in too much, and there is no shortage of pushing. As a result, the reliability of the state detection operation in the electric lock can be improved.

The coil spring is always compressed when On the other hand, when receiving a reaction force from the switch, the coil spring is always compressed. That is, when transmitting the sliding force to the driven plate, the coil spring transmits the sliding force with a predetermined variable width by a variable urging force, and ensures a certain allowable range for the driving force for sliding the driven plate. On the other hand, when it receives a reaction force from the switch, it absorbs the reaction force by compressing itself, and when the gear, slide member, driven plate, or switch is directly connected, it reacts against any of these members. The force is prevented from being applied as an excessive force. That is, the coil spring can function as a buffering connecting member.

DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of an electric lock state detection mechanism according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a structural explanatory view showing a side view of a state detection mechanism of an electric lock according to a first embodiment of the present invention, and FIG. It is explanatory drawing which showed the exploded perspective view of the principal part which showed (a) and the principal part enlarged plan view in (b).
The electric lock state detection mechanism 200 according to the first embodiment is incorporated in the electric lock 11. In the electric lock 11, an electric motor 15 that is an electric actuator is installed in the lock box 13, and the electric motor 15 meshes the pinion 17 with the drive gear 19. The rotation of the drive gear 19 is transmitted to the driven gear 27a of the Dharma shaft 27 through the first gear 21, the second gear 23, and the third gear 25 that are sequentially meshed. The drive gear 19 is engaged with the third gear 25 via the sub first gear 21a and the sub second gear 23a.

  In the lock box 13 in the vicinity of the Dharma shaft 27, a dead bolt 31 that is advanced and retracted from a front panel 29 fixed to a notch of a door (not shown) is provided so as to be slidable in a horizontal direction (left and right direction in FIG. 1). ing. The dead bolt 31 is urged by the urging spring 33 in the direction of retreating into the lock box 13. The backward movement of the dead bolt 31 is regulated by the swing stopper 35 being hooked. An operating rod 27 b is provided on the Dalma shaft 27, and the operating rod 27 b presses the protrusion 31 a of the dead bolt 31 by the clockwise rotation of the Dalma shaft 27, and pushes the dead bolt 31 against the biasing force of the biasing spring 33. Project from the front panel 29. The protruding dead bolt 31 is held in a protruding state by the swing stopper 35 being hooked.

  When the electric motor 15 is driven in the unlocking direction, the Dharma shaft 27 rotates counterclockwise in FIG. 1 via the drive gear 19, the first gear 21, the second gear 23, and the third gear 25. A stopper release rod (not shown) releases the swing stopper 35 and the operating rod 27b moves in a direction in which the dead bolt 31 is retracted. Thereby, the dead bolt 31 is retracted into the lock box 13 by the biasing force of the biasing spring 33. In other words, the electric lock 11 transmits the turning force of the electric motor 15 to the Dalma shaft 27 via the gear, and the dead bolt 31 is advanced and retracted by the rotation of the Dalma shaft 27 to enable locking and unlocking.

  A state detection mechanism 200 is provided near the second gear 23 on the inner surface of the back plate 37 of the lock box 13. The state detection mechanism 200 includes a slide member 39, a driven plate 41A, coil springs 43a and 43b, a lock detection switch 47, an unlock detection switch 49, and an auxiliary switch 50.

  As shown in FIG. 2, the slide member 39 is held parallel to the back plate 37 so as to be movable in the vertical direction in FIG. 1, and has a pair of spring seats 39b and 39c formed by cutting and raising at the base portion 39a. is doing. Further, an engaging shaft 39e protrudes from a side wall 39d erected from the base 39a. The slide member 39 reciprocates as the engagement shaft 39e abuts on a part of the second gear 23 (a part of the tooth portion) and follows the forward and reverse rotation of the second gear 23.

  The driven plate 41A is held in parallel with the back plate 37 so as to be movable in the vertical direction of FIG. 1, and has a frame portion 41b in which a pair of spring seats 39b and 39c are arranged on the inner side of the base portion 41a. The frame portion 41b is formed with a pair of spring receivers 41c and 41d that face the pair of spring seats 39b and 39c in the reciprocating direction. The base 41a is provided with a pressing plate 41g that protrudes from the driven plate 41A perpendicular to the reciprocating direction. In the lock box 13, a lock detection switch 47, an unlock detection switch 49 and an auxiliary switch 50 are arranged to face each other. The pressing plate 41g is disposed between the opposing lock detection switch 47, the unlock detection switch 49, and the auxiliary switch 50. The pressing plate 41g presses the locking detection switch 47 with the forward slide of the driven plate 41A, and presses the unlocking detection switch 49 and the auxiliary switch 50 with the backward sliding.

  The pressing plate 41g is formed by bending the base 41a. A rib 41h for increasing the strength is provided at the bent portion of the base 41a and the pressing plate 41g. A plurality of warped portions 41j bulge on the front and back surfaces of the pressing plate 41g, and the surface of the warped portion 41j is formed with a smooth curved surface. The pressing plate 41g is formed with a smoothly curved warped portion 41j, so that the lock detection switch 47, the unlock detection switch 49, and the operation pieces 47b, 49b, 50b of the auxiliary switch 50 are prevented from being caught. The operating pieces 47b, 49b, 50b are pressed to press the pressing members 47a, 49a, 50a of the locking detection switch 47, the unlocking detection switch 49, and the auxiliary switch 50. Contact signals that are opened and closed by pressing the pressing elements 47 a, 49 a, and 50 a are detected by a control device such as a management room via the connector cable 53.

  A pair of coil springs 43a and 43b are sandwiched between the pair of spring seats 39b and 39c of the slide member 39 and the pair of spring receivers 41c and 41d of the driven plate 41A.

Next, the operation of the state detection mechanism of the electric lock configured as described above will be described.
FIG. 3 is an operation explanatory view showing the state of pressing the locking detection switch in (a) and the state of pressing the unlocking detection switch in (b).
When a lock signal is output from the management room or the like to the electric lock 11, the electric motor 15 is driven, and the drive gear 19 is rotated clockwise in FIG. By rotating the drive gear 19 clockwise, the Dharma shaft 27 is rotated clockwise via the first gear 21, the second gear 23, and the third gear 25. When the dharma shaft 27 rotates clockwise, the operating rod 27b presses the projection 31a, and the dead bolt 31 protrudes to be in a locked state.

  At this time, as the second gear 23 rotates clockwise, the slide member 39 is slid downward in FIG. 1 via the engagement shaft 39e. When the slide member 39 is slid downward, the coil spring 43a is compressed via the spring seat 39b, and the spring receiver 41c of the driven plate 41A is pressed by the repulsive force of the compression force. The driven plate 41A is slid downward in FIG. 1 by the repulsive force of the coil spring 43a.

  When the driven plate 41A is slid downward in FIG. 1, the operating piece 47b and the pressing element 47a of the locking detection switch 47 are pressed through the pressing plate 41g of the driven plate 41A. Thereby, the lock detection switch 47 closes the contact of the lock circuit, and the contact operating state is detected by the connector cable 53, so that the lock state of the electric lock 11 is detected by a control device such as a management room. It will be.

  The unlock detection by sending the unlock signal is performed in the case of the above-described lock detection operation, as well as the electric motor 15, the drive gear 19, the first gear 21, the second gear 23, the third gear 25, the Dharma shaft. 27, the dead bolt 31, the slide member 39, and the driven plate 41A are reversely operated, and the pressing member 49a of the unlocking detection switch 49 is pressed, so that the unlocking state of the electric lock 11 is controlled by a control device such as a management room. It will be detected.

  Thus, in the state detection mechanism 200, the reciprocating motion of the slide member 39 interlocked with the forward / reverse rotation of the second gear 23 is transmitted to the driven plate 41A via the coil springs 43a and 43b. Therefore, the driven plate 41A is slid only after the coil springs 43a and 43b are compressed with a predetermined compressive force. On the other hand, if the pressing plate 41g receives the reaction force from the switch, the reaction force is applied to the coil springs 43a and 43b via the driven plate 41A, and the coil springs 43a and 43b are further compressed.

  Here, as shown in FIG. 3, the reciprocating slide distance S2 of the driven plate 41A slid through the coil springs 43a and 43b is shorter than the reciprocating slide distance S1 of the slide member 39 (S1> S2). That is, when the reciprocating motion of the slide member 39 is transmitted to the driven plate 41A, the coil springs 43a and 43b are necessarily compressed. Conversely, the coil springs 43a and 43b are always compressed when a reaction force is received from the switch.

  That is, when transmitting the sliding force to the driven plate 41A, the coil springs 43a and 43b transmit the sliding force with a predetermined variable width by a variable urging force, and have a certain allowable driving force for sliding the driven plate 41A. Secure the range. On the other hand, when the reaction force from the switch is received, the reaction force is absorbed by being compressed, and the gear, the slide member 39, the driven plate 41A, the lock detection switch 47, and the unlock detection switch 49 are directly connected. In this case, the reaction force is prevented from being applied as an excessive force to any of these members. That is, the coil springs 43a and 43b function as buffering coupling members.

  Therefore, according to the state detection mechanism 200 of the electric lock 11 according to the present embodiment, the slide member 39 that reciprocates following the second gear 23 that moves the dead bolt 31 forward and backward, and the spring seat 39b of the slide member 39, A driven plate 41A on which spring receivers 41c and 41d facing 39c are formed, and coil springs 43a and 43b sandwiched between the spring seats 39b and 39c and the spring receivers 41c and 41d, perpendicular to the reciprocating direction. The second gear is provided with a pressing plate 41g that protrudes from the driven plate 41A and presses the locking detection switch 47 with the forward slide of the driven plate 41A and presses the unlocking detection switch 49 with the backward slide. The reciprocating motion of the slide member 39 interlocking with the normal / reverse rotation of the 23 is transmitted to the driven plate 41A via the coil springs 43a and 43b. Pressing plate 41g is actuated by the reciprocating.

  That is, after the coil springs 43a and 43b are compressed with a predetermined compression force, the driven plate 41A is slid for the first time, and if the pressing plate 41g receives the reaction force from the switch, the reaction force is transmitted via the driven plate 41A. Applied to the coil springs 43a and 43b, the coil springs 43a and 43b are further compressed. As a result, the switch pressing members 47a, 49a and 50a in the state detection mechanism 200 of the electric lock 11 can be optimally operated so as not to be pushed in excessively and insufficiently pressed. As a result, the reliability of the state detection operation 200 in the electric lock 11 can be improved. In addition, since the pressing plate 41g protrudes vertically from the driven plate 41A, the pressing plate 41g is disposed between the locking detection switch 47 and the unlocking detection switch 49 which are opposed to each other, so that the driven plate can be driven with a simple structure. The locking detection switch 47 and the unlocking detection switch 49 can be reliably operated by the reciprocation of the plate 41A.

Next, a second embodiment of the electric lock state detection mechanism according to the present invention will be described.
4A is a side view of the state detection mechanism for an electric lock according to the second embodiment of the present invention, and FIG. FIG.
The electric lock state detection mechanism 100 according to the present embodiment is incorporated in the electric lock 11. In the electric lock 11, an electric motor 15 that is an electric actuator is installed in the lock box 13, and the electric motor 15 meshes the pinion 17 with the drive gear 19. The rotation of the drive gear 19 is transmitted to the driven gear 27a of the Dharma shaft 27 through the first gear 21, the second gear 23, and the third gear 25 that are sequentially meshed. The drive gear 19 is engaged with the third gear 25 via the sub first gear 21a and the sub second gear 23a.

  In the lock box 13 in the vicinity of the Dharma shaft 27, a dead bolt 31 which is advanced and retracted from a front panel 29 fixed to a notch of a door (not shown) is provided so as to be slidable in a horizontal direction (left and right direction in FIG. 4). ing. The dead bolt 31 is urged by the urging spring 33 in the direction of retreating into the lock box 13. The backward movement of the dead bolt 31 is regulated by the swing stopper 35 being hooked. An operating rod 27 b is provided on the Dalma shaft 27, and the operating rod 27 b presses the protrusion 31 a of the dead bolt 31 by the clockwise rotation of the Dalma shaft 27, and pushes the dead bolt 31 against the biasing force of the biasing spring 33. Project from the front panel 29. The protruding dead bolt 31 is held in a protruding state by the swing stopper 35 being hooked.

  When the electric motor 15 is driven in the unlocking direction, the Dharma shaft 27 rotates counterclockwise in FIG. 4 via the drive gear 19, the first gear 21, the second gear 23, and the third gear 25. A stopper release rod (not shown) releases the swing stopper 35 and the operating rod 27b moves in a direction in which the dead bolt 31 is retracted. Thereby, the dead bolt 31 is retracted into the lock box 13 by the biasing force of the biasing spring 33. In other words, the electric lock 11 transmits the turning force of the electric motor 15 to the Dalma shaft 27 via the gear, and the dead bolt 31 is advanced and retracted by the rotation of the Dalma shaft 27 to enable locking and unlocking.

  A state detection mechanism 100 is provided in the vicinity of the second gear 23 on the inner surface of the back plate 37 of the lock box 13. The state detection mechanism 100 includes a slide member 39, a driven plate 41, coil springs 43 a and 43 b, a swing plate 45, a lock detection switch 47, and an unlock detection switch 49.

  As shown in FIG. 5, the slide member 39 is held parallel to the back plate 37 so as to be movable in the vertical direction of FIG. 4, and has a pair of spring seats 39b and 39c formed by cutting and raising at the base portion 39a. is doing. Further, an engaging shaft 39e protrudes from a side wall 39d erected from the base 39a. The slide member 39 reciprocates as the engagement shaft 39e abuts on a part of the second gear 23 (a part of the tooth portion) and follows the forward and reverse rotation of the second gear 23.

  The driven plate 41 is held in parallel with the back plate 37 so as to be movable in the vertical direction of FIG. 4, and has a frame portion 41b in which a pair of spring seats 39b and 39c are arranged on the inner side of the base portion 41a. The frame portion 41b is formed with a pair of spring receivers 41c and 41d that face the pair of spring seats 39b and 39c in the reciprocating direction. The base portion 41a is provided with two pairs of convex portions 41e and 41f spaced apart in the reciprocating direction on one plate surface side.

  A pair of coil springs 43 a and 43 b are sandwiched between the pair of spring seats 39 b and 39 c of the slide member 39 and the pair of spring receivers 41 c and 41 d of the driven plate 41.

  A swing plate 45 is provided in the lock box 13 so as to face the lock detection switch 47 and the unlock detection switch 49, and the swing shaft 51 swings about the swing shaft 51 perpendicular to the reciprocating direction of the driven plate 41. It is supported freely.

The swing plate 45 swings toward the other end side (clockwise in FIG. 4) when one convex portion 41e of the driven plate 41 sliding in the forward direction (downward in FIG. 4) is in sliding contact with the inclined surface 45a. The presser 47a of the lock detection switch 47 is pressed.
Further, the swinging plate 45 swings to one end side by sliding the other convex portion 41f of the driven plate 41 sliding in the backward direction (upward direction in FIG. 4) to the inclined surface 45b. The pressing element 49a is pressed.
Contact signals that are opened and closed by pressing the pressing elements 47a and 49a are detected by a control device such as a management room via the connector cable 53.

  Here, the shape of the oscillating plate 45 will be described in detail. The oscillating shaft 51 is arranged closer to one surface side with respect to the thickness of the oscillating plate 45. In the present invention, each of the detection switches 47 and 49 is arranged. Located on the side close to the. Further, as shown in FIG. 5, the swing plate 45 has a substantially rhombus cross section so that the thickness decreases toward both ends, and the surface side facing the detection switches 47 and 49 is formed substantially smooth, and the back surface side. The inclined surfaces 45a and 45b are formed. Each inclined surface 45a, 45b is located in a pair of recesses formed on the back surface of the swing plate 45, and forms a substantially uniform thickness between the bottom surface of each recess and the surface of the swing plate 45, and further It becomes the surface which inclines toward both ends. In other words, the inclined surfaces 45a and 45b are arranged in a C shape in a cross-sectional view toward both ends as the swing plate 45. Accordingly, the convex portions 41e and 41f of the driven plate 41 can move in the concave portions, and the swing of the swing plate 45 caused by the sliding contact of the convex portions 41e and 41f of the driven plate 41 is convex. This is performed by sliding and pressing the inclined surfaces 45a and 45b by the portions 41e and 41f. For example, even when each of the inclined surfaces 45a and 45b has a predetermined length, 41e and 41f will press.

Next, the operation of the state detection mechanism of the electric lock configured as described above will be described.
6A and 6B are operation explanatory views showing the locking detection switch pressing state of the state detection mechanism shown in FIG. 4 in FIG. 4A and the unlocking detection switch pressing state in FIG.
When a lock signal is output from the management room or the like to the electric lock 11, the electric motor 15 is driven, and the drive gear 19 is rotated clockwise in FIG. By rotating the drive gear 19 clockwise, the Dharma shaft 27 is rotated clockwise via the first gear 21, the second gear 23, and the third gear 25. When the dharma shaft 27 rotates clockwise, the operating rod 27b presses the projection 31a, and the dead bolt 31 protrudes to be in a locked state.

  At this time, the second gear 23 rotates clockwise, whereby the slide member 39 is slid downward in FIG. 4 via the engagement shaft 39e. When the slide member 39 is slid downward, the coil spring 43a is compressed via the spring seat 39b, and the spring receiver 41c of the driven plate 41 is pressed by the repulsive force of the compression force. The driven plate 41 is slid downward in FIG. 4 by the repulsive force of the coil spring 43a.

  When the driven plate 41 is slid downward in FIG. 4, the convex portion 41 e of the driven plate 41 pushes up the inclined surface 45 a of the swing plate 45, and the swing plate 45 is swung so that the lock detection switch 47 The pressing element 47a is pressed. Thereby, the lock detection switch 47 closes the contact of the lock circuit, and the contact operating state is detected by the connector cable 53, so that the lock state of the electric lock 11 is detected by a control device such as a management room. It will be.

  The unlock detection by sending the unlock signal is performed in the case of the above-described lock detection operation, as well as the electric motor 15, the drive gear 19, the first gear 21, the second gear 23, the third gear 25, the Dharma shaft. 27, the dead bolt 31, the slide member 39, the driven plate 41, and the swing plate 45 are operated in reverse, and the pressing member 49a of the unlock detection switch 49 is pressed, so that the electric lock 11 is controlled by a control device such as a management room. The unlocked state is detected.

  Thus, in the state detection mechanism 100, the reciprocating motion of the slide member 39 interlocked with the forward / reverse rotation of the second gear 23 is transmitted to the driven plate 41 via the coil springs 43a and 43b. The swing plate 45 is swung. Therefore, the driven plate 41 is slid only after the coil springs 43a and 43b are compressed with a predetermined compressive force. On the other hand, when the rocking plate 45 receives a reaction force from the switch, the reaction force is applied to the coil springs 43a and 43b via the driven plate 41, and the coil springs 43a and 43b are further compressed.

  Here, as shown in FIG. 6, the reciprocating slide distance S2 of the driven plate 41 slid through the coil springs 43a and 43b is shorter than the reciprocating slide distance S1 of the slide member 39 (S1> S2). That is, when the reciprocating motion of the slide member 39 is transmitted to the driven plate 41, the coil springs 43a and 43b are necessarily compressed. Conversely, the coil springs 43a and 43b are always compressed when a reaction force is received from the switch.

  That is, when transmitting the sliding force to the driven plate 41, the coil springs 43a and 43b transmit the sliding force with a predetermined variable width by a variable urging force, and have a certain allowable driving force for sliding the driven plate 41. Secure the range. On the other hand, when the reaction force from the switch is received, the reaction force is absorbed by being compressed, and the gear, the slide member 39, the driven plate 41, the lock detection switch 47, and the unlock detection switch 49 are directly connected. In this case, the reaction force is prevented from being applied as an excessive force to any of these members. That is, the coil springs 43a and 43b function as buffering coupling members.

  Therefore, according to the state detection mechanism 100 of the electric lock 11 according to the present embodiment, the slide member 39 that reciprocates following the second gear 23 that moves the dead bolt 31 back and forth, and the spring seat 39b of the slide member 39, A follower plate 41 on which spring receivers 41c and 41d facing 39c are formed, and coil springs 43a and 43b sandwiched between the spring seats 39b and 39c and the spring receivers 41c and 41d, are supported in a swingable manner. Since the protrusions 41e and 41f of the sliding follower plate 41 are provided with the rocking plate 45 that presses the locking detection switch 47 or the unlocking detection switch 49 by sliding contact, the second gear 23 is interlocked with forward and reverse rotation. The reciprocating motion of the slide member 39 is transmitted to the driven plate 41 via the coil springs 43a and 43b, and the swinging plate 45 is swung by the reciprocating motion of the driven plate 41.

  That is, after the coil springs 43a and 43b are compressed with a predetermined compression force, the driven plate 41 is slid for the first time, and if the oscillating plate 45 receives the reaction force from the switch, the reaction force is transmitted via the driven plate 41. Is applied to the coil springs 43a and 43b, and the coil springs 43a and 43b are further compressed. As a result, the switch pressing elements 47a and 49a in the state detecting mechanism 100 of the electric lock 11 can be optimally operated so as not to be pushed in excessively and insufficiently pressed. As a result, the reliability of the state detection operation 100 in the electric lock 11 can be improved.

In the first and second embodiments described above, the pair of coil springs 43a and 43b are sandwiched between the spring seats 39b and 39c and the spring receivers 41c and 41d of the slide member 39 and the driven plates 41A and 41, respectively. As an example, that is, as the structure of each part, it is composed of flat plate members and a pair of coil springs is shown. As shown in FIG. 7, the shape of the slide member 39A is a box part 39g. The coil springs 43a and 43b may be accommodated in the box 39g.
According to this example, as shown in FIG. 7, the follower plate 41B is formed in a substantially L shape and has a pressing plate 41g as in the first embodiment, and has a plate-like protrusion in the middle. A piece 41k is protruded, and the front and back plate surfaces of the protrusion 41k are spring receivers 41c and 41d. Each of the spring receivers 41c and 41d faces the reciprocating direction. The pressing plate 41g is disposed between the locking detection switch 47, the unlocking detection switch 49, and the auxiliary switch 50 that are disposed to face each other in the lock box 13, and is slidable along the back plate 37. The pressing plate 41g presses the locking detection switch 47 with the forward slide of the driven plate 41B, and presses the unlocking detection switch 49 and the auxiliary switch 50 with the backward sliding.

  As shown in FIG. 7, the slide member 39 </ b> A includes a box portion 39 g that is held movably in parallel with the back plate 37 and is formed in a substantially rectangular box shape with one side facing the back plate 37 opening. . In addition, this box part 39g sets the longitudinal direction to a reciprocating direction. Further, an arm portion 30f extends from one end of the box portion 39g, and an engagement shaft 39e is provided at the tip of the arm portion 39f. The engagement shaft 39e is in contact with the cam plate 23a fixed to the second gear 23, and reciprocates following the forward and reverse rotation of the second gear 23. The inner surfaces of the inner surface of the box portion 39g facing each other in the reciprocating direction constitute a pair of spring seats 39b and 39c.

  As shown in FIG. 8, the driven plate 41B and the slide member 39A are arranged such that the projecting piece 41k is housed in the box portion 39g, and a portion of the driven plate 41B is covered by the box portion 39g of the slide member 39A. Composed of position. The spring receivers 41c and 41d, which are both surfaces of the projecting piece 41k, face the spring seats 39b and 39c in the box portion 39g, respectively. A pair of coil springs 43a and 43b are sandwiched between the spring seats 39b and 39c and the spring receivers 41c and 41d.

  Although not shown, a plurality of warped portions may be bulged on the front and back surfaces of the pressing plate 41g as in the first embodiment, or each switch 47, 49, 50 It is good also as providing a buffer convex part etc. in the site | part which presses the presser 47a, 49a, 50a. Providing such warts and shock-absorbing protrusions can prevent the occurrence of a pressing failure with respect to each of the switches 47, 49, 50, and ensures a reliable switch operation.

  In the electric lock state detection mechanism configured as described above, as shown in the operation explanatory diagrams of FIGS. (A) and (b), by driving the electric motor (see FIG. 1) by the lock signal to the electric lock, Through the first gear 21 and the second gear 23, the slide member 39A slides through the engagement shaft 39e. When the slide member 39A is slid, the coil spring 43a is compressed via the spring seat 39b, and the spring receiver 41c of the driven plate 41B is pressed by the repulsive force of the compression force. The driven plate 41B is slid by the repulsive force of the coil spring 43a (left side in FIG. 8).

  When the driven plate 41B is slid, the pressing element 47a of the locking detection switch 47 is pressed through the pressing plate 41g of the driven plate 41B. As a result, the lock detection switch 47 detects the lock state of the electric lock by closing the contact of the lock circuit and detecting the contact operating state.

  In addition, the unlocking detection by sending the unlocking signal is the same as the above-described unlocking detection operation, and each part is reversely operated, and the pressing member 49a of the unlocking detection switch 49 is pressed, so that the electric lock The unlocked state will be detected.

  As described above, in the state detection mechanism 300 according to this embodiment, the reciprocating motion of the slide member 39A interlocked with the forward and reverse rotation of the second gear 23 is performed by the coil springs 43a and 43b, as in the first embodiment described above. Is transmitted to the driven plate 41B. Therefore, the driven plate 41B is slid only after the coil springs 43a and 43b are compressed with a predetermined compressive force. On the other hand, when the pressing plate 41g receives a reaction force from the switch, the reaction force is applied to the coil springs 43a and 43b via the driven plate 41B, and the coil springs 43a and 43b are further compressed.

  As shown in FIG. 8, the reciprocating slide distance S2 of the driven plate 41B slid through the coil springs 43a and 43b is shorter than the reciprocating slide distance S1 of the slide member 39A (S1> S2). That is, when the reciprocating motion of the slide member 39A is transmitted to the driven plate 41B, the coil springs 43a and 43b are necessarily compressed. Conversely, the coil springs 43a and 43b are always compressed when a reaction force is received from the switch.

  That is, when transmitting the sliding force to the driven plate 41B, the coil springs 43a and 43b transmit the sliding force with a predetermined variable width by a variable urging force, and have a certain allowable driving force for sliding the driven plate 41B. Secure the range. On the other hand, when the reaction force from the switch is received, the reaction force is absorbed by being compressed, and the gear, the slide member 39A, the driven plate 41B, the lock detection switch 47, and the unlock detection switch 49 are directly connected. In this case, the reaction force is prevented from being applied as an excessive force to any of these members. That is, the coil springs 43a and 43b function as buffering coupling members.

  Therefore, according to the state detection mechanism 300 of the electric lock 11 according to this embodiment, the slide member 39A that reciprocates following the second gear 23 that moves the dead bolt 31 forward and backward, and the spring seat 39b of the slide member 39A, A driven plate 41B formed with spring receivers 41c and 41d facing 39c, and coil springs 43a and 43b sandwiched between the spring seats 39b and 39c and the spring receivers 41c and 41d, perpendicular to the reciprocating direction. The second gear is provided with a pressing plate 41g that protrudes from the driven plate 41B and presses the locking detection switch 47 with the forward slide of the driven plate 41B and presses the unlocking detection switch 49 with the backward slide. The reciprocating motion of the slide member 39A interlocking with the normal / reverse rotation of the 23 is transmitted to the driven plate 41B via the coil springs 43a and 43b. Pressing plate 41g is actuated by the reciprocating movement of the plate 41B.

  That is, after the coil springs 43a and 43b are compressed with a predetermined compression force, the driven plate 41B is slid for the first time, and when the pressing plate 41g receives the reaction force from the switch, the reaction force is transmitted via the driven plate 41B. Applied to the coil springs 43a and 43b, the coil springs 43a and 43b are further compressed. As a result, the switch pressing members 47a, 49a, and 50a in the state detection mechanism 300 of the electric lock 11 can be optimally operated so as not to be pushed in excessively and insufficiently pressed. As a result, the reliability of the state detection operation 300 in the electric lock 11 can be improved. Further, since the pressing plate 41g protrudes vertically from the driven plate 41B, the pressing plate 41g is arranged between the opposed locking detection switch 47 and the unlocking detection switch 49, so that the driven plate can be driven with a simple structure. The lock detection switch 47 and the unlock detection switch 49 can be reliably operated by the reciprocating motion of the plate 41B.

  Further, according to this embodiment, the slide member 39A is provided with the box portion 39g and the structure covers the pair of coil springs 43a and 43b, so that dust or the like adheres to the coil springs 43a and 43b, for example, locks. It is possible to suppress dust entering from the outside of the box and buffering with other parts in the lock box, and it is possible to reduce the occurrence of malfunctions when used over time. The spring seats 39b and 39c and the spring receivers 41c and 41d formed by the box portion 39g and the protruding piece 41k of the driven plate 41B accommodated in the box portion 39g are substantially flat. Therefore, the pair of coil springs 43a and 43b sandwiched between them can be easily assembled, that is, assembly can be performed in the box 39g.

  In the first and second embodiments described above, the configuration in which the pressing plate 41g is provided on the driven plate 41A and the configuration in which the driven plate 41 and the swing plate 45 are combined have been described as examples. The state detection mechanism of the electric lock may use various configurations in place of the pressing plate 41g and the swing plate 45. For example, although the pressing plate 41g protrudes perpendicularly to the base portion 41a, the pressing plate 41g may be formed as a pressing piece that is bent in an L shape on the same plane as the base portion 41a. In addition, the tip of the swing rod of a swing switch whose contact is opened and closed by swinging of the swing rod may be directly connected to the base 41a via a rotating shaft. Further, a rack as a gear is formed on the side edge of the base 41a, and a segment gear engaged with the rack is swung and rotated to open and close the contact of the switch via the segment gear. Also good. Furthermore, in each embodiment, each switch is configured to operate when pressed, but may be configured with a non-contact type switch.
