The connection between the drive piece 68 and the plunger 48 forms a slit groove 69 in the diameter direction at the tip of the plunger 48, and the pin 70 is inserted so as to cross the slit groove 69. A portion is loosely inserted into the slit groove 69, and an engagement groove 71 opened at the tip of the drive piece 68 is engaged with the pin 70.

  The plunger 48 has a compression coil spring 74 wound between the main body 72 of the solenoid 9 and a locking ring 73 such as an E ring externally attached to the front end, and is resilient in the direction in which the plunger 48 protrudes. I'm upset. In addition, a compression coil spring 75 is interposed between the proximal end of the linkage 47 and the inner wall of the drive storage container 52, and the linkage 47 is elastically biased in a direction to project from the drive storage container 52. ing. The inclined surface 66 is formed on the tip of the connecting member 47 so as to be inclined toward the tip side in a portion projecting laterally, and the connecting portion 46 of the regulating member 32 is attached to the connecting member 47 at the tip. It is connected by the rotation joint structure. In this rotary joint structure, as shown in FIGS. 9, 10 and 13, two dowels 77, 77 are provided in a diameter direction at the tip of a shaft 76 provided at the tip of the link 47. On the other hand, an insertion hole 78 conforming to the outer shape of the shaft 76 and the dowels 77, 77 is formed in the linking part 46 of the restriction member 32, and the shaft 76 and the dowels 77, 77 are inserted into the insertion hole 78. The restricting member 32 is rotated by 90 ° in a state where the dowels 77 and 77 penetrate the insertion hole 78 and used in a state in which it is prevented from coming off. Since the linking tool 47 and the regulating member 32 are used by being linked in a straight line, they are formed so that they can be inserted in a direction different by 90 ° from the direction.

  Further, although the tip end of the dead bolt 62 of the mechanical lock 7 is a tip sliding portion 65 in sliding contact with the inclined surface 66 of the link tool 47, specifically, the tip sliding portion 65 is the inclined surface It is formed by the same slope as 66. The end of the dead bolt 62 may be bent to form the end sliding portion 65.

  First, in order to bring the door into the unlocked state by using the electric lock 6, the dark spot number is input to the authentication means 10 on the surface side of the door 2, and when the solenoid 9 is energized upon receiving a command from its control circuit, The plunger 48 is drawn toward the main body 72 against the elastic biasing force of the compression coil spring 74 to rotate the cam member 49 clockwise as shown in FIG. In a state of being in contact with the locking portion 64, the link tool 47 is slidingly displaced so as to be drawn into the inside of the drive portion storage container 52 against the elastic biasing force of the compression coil spring 75. Naturally, the restricting member 32 is slidingly displaced in the same manner as the sliding displacement of the link tool 47, and the positions of the restricting convex portion 36 of the restricting member 32 and the convex portion 33 of the arm portion 31 of the pull 3 are shifted. 3 can be pulled forward for rotation, whereby the interlocking piece 53 of the interlocking member 28 of the latch drive mechanism 14 is pushed by the operation projection 54, the shaft 27 is rotated, and the latch 5 is rotated to rotate the housing 1 The door 2 can be opened by releasing the engagement with the buttocks.

  Then, when the energization to the solenoid 9 is cut off, the plunger 48 is protruded by the elastic biasing force of the compression coil spring 74, and the coupling tool 47 is removed from the drive storage container 52 by the elastic biasing force of the compression coil spring 75. The position of the control convex portion 36 of the restricting member 32 and the position of the convex portion 33 of the arm portion 31 of the pull 3 coincide with each other, and the front plate 15 of the door 2 and the pull 3 are pulled. Since the regulating member 32 is sandwiched between them, the further rotation is regulated, whereby the engagement of the latch 5 with the collar of the housing 1 is maintained, and the locking device 4 is locked.

  Here, when the solenoid 9 can not be energized due to any failure such as battery exhaustion, that is, when it is necessary to open the door 2 in an emergency, the key 61 is inserted from the finger entry space 12 into the key hole 11 to When the 7 is rotated in the unlocked state, the dead bolt 62 protrudes in the direction of the arrow in FIG. 9 (b), and the tip sliding portion 65 presses the inclined surface 66 of the linkage 47, and the inclined surface 66 retracts. Force acts in the direction in which the linkage 47 is drawn into the drive storage container 52, and the linkage 47 resists the elastic biasing force of the compression coil spring 75. The restricting member 32 can be slide-displaced in the unlocked state in the same manner as when the solenoid 9 is pulled in and the solenoid 9 is energized, so that the puller 3 can be pulled forward and the latch 5 is rotated. It can open the door 2 by releasing the engagement with rail portion of the housing 1 so. At this time, the locking portion 64 of the linkage 47 is separated from the operation piece 63 of the cam member 49 and operates independently of the cam member 49.

  Further, when the key 61 is locked from the emergency unlocking state, the dead bolt 62 retreats in the opposite direction, and the link tool 47 is in the direction of protruding from the drive storage container 52 by the elastic biasing force of the compression coil spring 75. The sliding displacement is performed, and the regulating member 32 is also slidingly displaced to return to the initial state, and the locking device 4 is locked.

Of course, depending on the mounting direction of the main body case 40 of the operation unit 8, the positional relationship between the pull handle frame 44, the mechanism accommodating portion 50, and the control accommodating portion 51 is changed vertically and horizontally. It is common that the mechanical portion accommodating portion 50 is disposed on one side of the pull handle frame portion 44 and the control portion accommodating portion 51 is disposed on the other side. Here, the battery unit for supplying electric power to the electric lock 6 is attached to the back surface of the surface plate 15 outside the main body case 40 by an appropriate means, but is accommodated inside the control portion accommodation portion 51. It is also possible. The solenoid 9, the mechanical lock 7, the linkage 47, the cam member 49, etc. are incorporated in the drive storage container 52 in advance as shown in FIGS. It is fitted in the part accommodating part 50. Here, the pulls 3 are formed symmetrically with respect to the center line, and the control member 32 is reversed and used even if the position of the mechanical portion accommodation portion 50 provided in the main body case 40 of the operation unit 8 is reversed. As can be done, the relationship between the convex portion 33 and the concave portion 34, and the restriction convex portion 36 and the relief concave portion 35 are symmetrical even if they are reversed.

  Next, the linkage between the pull 3 and the latch drive mechanism 14 will be described. The latch 5 is fixed to an end portion, and the interlocking member 28 is integrally provided for rotation at an intermediate position of the shaft 27 rotatably mounted on the back surface of the surface plate 15 of the door 2. The interlocking piece 53 provided on the side is continuously in contact with the operation projection 54 extending in a direction parallel to the rotation center axis of the pull 3 continuously to the convex portion 33 formed on the arm portion 31 of the pull 3 .

  The handle 3 is rotatably provided in the main body case 40 of the operation unit 8, and the locking device 4 and the restricting member 32 are assembled. An arch-shaped recessed portion 55 is provided between it and the protruding portion 33, and a U-shaped recessed portion 56 opened to the front side is formed in the main body case portion 40 on the extension line thereof. When attaching the shaft 27 to the U-shaped recess 56 of the main body case 40 and the interlocking member 28 to the recess 55 of the pull 3 while attaching the shaft 27 to the back of the face plate 15, the arm piece 53 It comes in contact with the operation projection 54 of 31.

  On both ends of the interlocking member 28, pressing pieces 57, 57 are provided on the side opposite to the side on which the interlocking piece 53 is provided, and a compression coil spring 58 is attached to the tip of the pressing piece 57; When the operation unit 8 is attached to the rear surface of the door 2, the compression coil spring 58 is held in compression and held against the abutment surface 59 provided in the vicinity of the U-shaped recess 56 of the main body case 40. Is resiliently biased in the direction of pressing the operation projection 54 of the pull 3. That is, the latch 5 is resiliently urged in a direction to engage with the engagement hole of the hook portion of the housing 1.

  Further, in the side surface of the pull handle frame portion 44 between the pull handle mounting space 38 and the mechanical portion accommodation portion 50 in the main body case portion 40 of the operation unit 8, the key hole 11 of the mechanical lock 7 is The opening 60 is formed to face the That is, as shown in FIG. 3, the keyhole 11 is provided on the upper surface portion of the finger entry space 12 hidden from the sight line, and the key 61 inserted into the finger entry space 12 is engaged with the key hole 11. When 7 is locked and unlocked, the dead bolt 62 of the mechanical lock 7 is linearly driven.

  The locking device 4 displaces a regulating member 32 linked in a contact state via a linkage 47 with a drive unit displaced by the locking / unlocking operation of the electric lock 6 to control opening / closing of the door 2 The restriction member 32 is unlocked independently of the electric lock 6 by the locking / unlocking mechanism and the dead bolt 62 of the mechanical lock 7 that performs the unlocking operation when the electric lock 6 becomes unusable in the locked state. And an emergency unlocking mechanism that forcibly displaces in a locking direction.

  The electric lock 6 is composed of a solenoid 9 and an authentication means 10 for issuing a command to energize or deenergize the solenoid 9. When the solenoid 9 is deenergized, the plunger 48 projects or retracts due to an elastic biasing force. When it is energized, the plunger 48 is displaced in the reverse direction against the elastic biasing force to be unlocked, and the regulating member 32 is elastically biased in the direction to be locked. The linkage mechanism between the regulating member 32 and the plunger 48 is a structure which is released when being displaced in the unlocking direction by the dead bolt 62 of the mechanical lock 7.

  The solenoid 9 is a pull type that pulls the plunger 48 against elastic biasing force when energized, and the linkage mechanism operates the cam member 49 that converts linear motion into rotational motion when the plunger 48 is pulled in. When the piece 63 is held against the locking portion 64 of the linkage 47 connected to the regulating member 32 by the elastic biasing force of the regulating member 32 and the mechanical lock 7 is operated to displace the dead bolt 62 And an emergency linkage mechanism for displacing the restricting member 32 in a direction in which the locking portion 64 of the linkage 47 is separated from the operation piece 63 against the elastic biasing force. Here, the emergency linkage mechanism presses the inclined surface 66 formed on the side surface of the linkage 47 connected to the restricting member 32 with the tip sliding portion 65 of the dead bolt 62 moving in a linear motion. The surface 66 is displaced in a direction to escape from the tip sliding portion 65.

More specifically, as shown in FIG. 9 and FIG. 10, the solenoid 9 and the mechanical lock 7 are stored inside the drive unit storage container 52 with the driving direction of the plunger 48 and the dead bolt 62 in parallel. The linkage 47 is slidably held in the direction perpendicular to the driving direction on the tip end side of the plunger 48 and the dead bolt 62. The cam member 49 is a member having a substantially L shape in a front view, and is rotatably held at a central portion by a support shaft 67 protrudingly provided inside the drive unit storage container 52, and one end portion of the cam member 49 Is the actuating piece 63, and the other end is a driving piece 68 rotatably coupled to the tip of the plunger 48. The connection between the drive piece 68 and the plunger 48 forms a slit groove 69 in the diameter direction at the tip of the plunger 48, and the pin 70 is inserted so as to cross the slit groove 69. A portion is loosely inserted into the slit groove 69, and an engagement groove 71 opened at the tip of the drive piece 68 is engaged with the pin 70.

  The plunger 48 has a compression coil spring 74 wound between the main body 72 of the solenoid 9 and a locking ring 73 such as an E ring externally attached to the front end, and is resilient in the direction in which the plunger 48 protrudes. I'm upset. In addition, a compression coil spring 75 is interposed between the proximal end of the linkage 47 and the inner wall of the drive storage container 52, and the linkage 47 is elastically biased in a direction to project from the drive storage container 52. ing. The inclined surface 66 is formed on the tip of the connecting member 47 so as to be inclined toward the tip side in a portion projecting laterally, and the connecting portion 46 of the regulating member 32 is attached to the connecting member 47 at the tip. It is connected by the rotation joint structure. In this rotary joint structure, as shown in FIGS. 9, 10 and 13, two dowels 77, 77 are provided in a diameter direction at the tip of a shaft 76 provided at the tip of the link 47. On the other hand, an insertion hole 78 conforming to the outer shape of the shaft 76 and the dowels 77, 77 is formed in the linking part 46 of the restriction member 32, and the shaft 76 and the dowels 77, 77 are inserted into the insertion hole 78. The restricting member 32 is rotated by 90 ° in a state where the dowels 77 and 77 penetrate the insertion hole 78 and used in a state in which it is prevented from coming off. Since the linking tool 47 and the regulating member 32 are used by being linked in a straight line, they are formed so that they can be inserted in a direction different by 90 ° from the direction.

  Further, although the tip end of the dead bolt 62 of the mechanical lock 7 is a tip sliding portion 65 in sliding contact with the inclined surface 66 of the link tool 47, specifically, the tip sliding portion 65 is the inclined surface It is formed by the same slope as 66. The end of the dead bolt 62 may be bent to form the end sliding portion 65.

  First, in order to bring the door into the unlocked state by using the electric lock 6, the dark spot number is input to the authentication means 10 on the surface side of the door 2, and when the solenoid 9 is energized upon receiving a command from its control circuit, The plunger 48 is drawn toward the main body 72 against the elastic biasing force of the compression coil spring 74 to rotate the cam member 49 clockwise as shown in FIG. In a state of being in contact with the locking portion 64, the link tool 47 is slidingly displaced so as to be drawn into the inside of the drive portion storage container 52 against the elastic biasing force of the compression coil spring 75. Naturally, the restricting member 32 is slidingly displaced in the same manner as the sliding displacement of the link tool 47, and the positions of the restricting convex portion 36 of the restricting member 32 and the convex portion 33 of the arm portion 31 of the pull 3 are shifted. 3 can be pulled forward for rotation, whereby the interlocking piece 53 of the interlocking member 28 of the latch drive mechanism 14 is pushed by the operation projection 54, the shaft 27 is rotated, and the latch 5 is rotated to rotate the housing 1 The door 2 can be opened by releasing the engagement with the buttocks.

  Then, when the energization to the solenoid 9 is cut off, the plunger 48 is protruded by the elastic biasing force of the compression coil spring 74, and the coupling tool 47 is removed from the drive storage container 52 by the elastic biasing force of the compression coil spring 75. The position of the control convex portion 36 of the restricting member 32 and the position of the convex portion 33 of the arm portion 31 of the pull 3 coincide with each other, and the front plate 15 of the door 2 and the pull 3 are pulled. Since the regulating member 32 is sandwiched between them, the further rotation is regulated, whereby the engagement of the latch 5 with the collar of the housing 1 is maintained, and the locking device 4 is locked.

  Here, when the solenoid 9 can not be energized due to any failure such as battery exhaustion, that is, when it is necessary to open the door 2 in an emergency, the key 61 is inserted from the finger entry space 12 into the key hole 11 to When the 7 is rotated in the unlocked state, the dead bolt 62 protrudes in the direction of the arrow in FIG. 9 (b), and the tip sliding portion 65 presses the inclined surface 66 of the linkage 47, and the inclined surface 66 retracts. Force acts in the direction in which the linkage 47 is drawn into the drive storage container 52, and the linkage 47 resists the elastic biasing force of the compression coil spring 75. The restricting member 32 can be slide-displaced in the unlocked state in the same manner as when the solenoid 9 is pulled in and the solenoid 9 is energized, so that the puller 3 can be pulled forward and the latch 5 is rotated. It can open the door 2 by releasing the engagement with rail portion of the housing 1 so. At this time, the locking portion 64 of the linkage 47 is separated from the operation piece 63 of the cam member 49 and operates independently of the cam member 49.

  Further, when the key 61 is locked from the emergency unlocking state, the dead bolt 62 retreats in the opposite direction, and the link tool 47 is in the direction of protruding from the drive storage container 52 by the elastic biasing force of the compression coil spring 75. The sliding displacement is performed, and the regulating member 32 is also slidingly displaced to return to the initial state, and the locking device 4 is locked.

  As shown in FIG. 10, the drive unit storage container 52 is composed of a main body container 79 and a lid 80, and the main body container 79 includes the aforementioned solenoid 9, mechanical lock 7, linkage 47, cam member 49, compression coil spring 75, etc. The lid 80 is fitted and fitted. As shown in FIG. 14, the drive unit storage container 52 assembled in this manner is fitted into the mechanical unit storage unit 50 of the operation unit 8 to incorporate the locking device 4 therein.

  As described above, the pull handle frame portion 44 is provided at the central portion of the main body case portion 40 of the operation unit 8, and the mechanical portion storage portion 50 is disposed on one side with the pull handle frame portion 44 interposed therebetween. Although the unit 51 is disposed, the mechanical unit accommodating unit 50 accommodates the solenoid 9, and the control unit accommodating unit 51 accommodates the authentication means 10 and the control circuit.
