JP6494500B2 - Base member of locking device and locking device using the same - Google Patents

Description

  The present invention relates to a base member of a lock device proposed as a completely new device, and more particularly to a lock device that can easily change the type of lock using the base member.

  Conventionally, a cylinder lock has been used as a door lock, but it has been a problem that it is easily unlocked by picking.

  As a countermeasure against picking, a card-type lock using a key card and a code card, such as a wing card (a registered trademark), has been developed. Briefly describing such a card-type locking device, it is to lock and unlock using a key card. When the key card is not inserted, it is stored in the lock by a locking pin inserted into a plurality of long holes. The movement of the actuating body is locked. If the key card is an appropriate one corresponding to the code card inserted in the locking device, the locking pin moves through the ball or the spring, so that the operating body can be moved. When the key card is further pushed in, the operating body moves from the stop position to an operable position and can be unlocked. When the key card is pulled back in the original direction from the operation position, the operating body also returns to the stop position, and when the key card is pulled, the operating body is locked by the locking pin.

  Furthermore, the applicant provided the card type lock device described in Patent Document 1 in order to improve the convenience of the manager of the apartment house with the diversification of the housing environment due to the increase in apartments and apartments. In the card lock device described in Patent Document 1, two lock bodies, a card type lock body and a cylinder lock body, are mounted in a case and operated in association with each other, and one card type lock body is mainly used for tenants. The other cylinder lock body is used for the manager, and in the housing complex, the card-type lock device is used, and the administrator uses the cylinder lock body to use the cylinder lock body in the master key state. In addition, since the administrator does not manage a large number of keys for each door, the management is easy and economical.

  Furthermore, the applicant has provided the card-type lock described in Patent Document 2 in consideration of the usage mode of the user. The card type lock device described in Patent Document 2 is provided with an inner case rotatably in a fixed outer case, and a card type lock body having an operating body is mounted in the inner case. The card case is inserted into the card-type lock body, and the inner case can be rotated by moving the operation body of the card-type lock body. In addition, by rotating and moving to the locking position and the unlocking position, a latch such as a dead bolt connected to the inner case is locked and unlocked. In condominiums such as apartments and apartments, The code card can be easily exchanged and managed easily.

  In this way, according to the diversification of the housing environment, family structure, and lifestyle, conventional locks have been improved for the convenience of the user, and a special IC card or the like is used for the solution. Various things such as an electronic type and a code number type have been developed.

  By the way, it is conceivable that the lock suitable for use changes depending on the diversification of the housing environment, the family structure, the lifestyle, and the purpose of using the room.

  For example, card-type locks are unlikely to be damaged by picking like cylinder locks, but they are used when there is an insertion slot on the side, or depending on the position of the insertion slot, for children who are still short May be difficult to select, especially for families with small children.

  In addition, since the electric lock has no keyhole, damage due to picking can be prevented and the crime prevention level can be raised, but when the battery is dead or power is not supplied to the drive mechanism or rainwater enters the lock It is difficult to deal with when the lock does not work.

  In addition, the PIN code lock does not require a key or card, and there is no risk of being unlocked by a lost or stolen key, but you can forget the PIN code or see the PIN code by others. I am worried about it.

  In this way, each lock has its advantages and disadvantages, and it is used appropriately and appropriately according to changes in family structure, lifestyle, and targeted crime prevention level. Since it is provided in combination with a door lock, when replacing it, it is necessary to open the door and disassemble and incorporate the door lock provided on the door, so that it cannot be easily replaced.

  In the future, in view of the fact that the need to change the type of lock is expected to increase due to further diversification of family structure and lifestyle, what can be easily exchanged by users and administrators is desired. .

The plate-shaped attaching / detaching protrusion 17 projecting from the side surface of the locking device 1 so as to protrude and retract in the radial direction is engaged with the base member 60 to be detachably attached to the door 90. A driver 18 that is operated when the locking device 1 is in the operating position protrudes at the rear end of the locking device 1 so that the driver 18 is dead when the locking device 1 is fixed to the base member 60. It is provided so as to be engageable with a door lock mechanism for controlling the movement of the bolt 93 and the like.

  As shown in FIG. 3, the base member 60 has a large-diameter portion 61 on the front side and a small-diameter portion 65 having a smaller diameter than the large-diameter portion 61 on the rear side. As shown in FIG. 2, a decorative ring 69 is screwed to the rear end portion of the large-diameter portion 61. The outer diameter of the small diameter portion 65 is formed to be an outer diameter that can be inserted into a cylinder lock installation hole 95 provided in the door 90, usually 44 mm. An insertion hole 651 for inserting the fixing pin 94 inserted from the door lock 91 is formed on the side surface of the small diameter portion 65. Thus, the base member 60 can be fixed to the door lock 91 by inserting the fixing pin 94 into the insertion hole 651, and the base member 60 can be removed from the door lock 91 when the fixing pin 94 is removed. In addition, in order to fix the base member 60 to the door lock 91 so that attachment or detachment is possible, an appropriate | suitable system other than said system can be used.

  The front end of the large-diameter portion 61 is formed so as to be inserted into the lock device 1 when the lock device 1 is attached to the base member 60. As a result, there is no gap between the base member 60 and the lock device 1 so that a breaking tool can be inserted from the outside.

  On the inner surface of the base member 60, as shown in FIG. 3, a main body housing portion 62 for housing the lock device 1 from the rear to the middle, and a connecting hole 66 through which the driver 18 is inserted are formed.

The engaging groove 621 has a shape in which the attaching / detaching protrusion 17 provided in the locking device can be fitted. It is preferable to form a plurality of engaging grooves 621 so that the angle at which the locking device 1 is attached can be selected.

  The engagement groove 621 is provided with a removal hole 611 so that a pin (not shown) or the like for inserting the detachable protrusion 17 fitted in the engagement groove 621 from the outside to be inserted in the radial direction can be inserted. is there.

  A step portion 64 is formed around the connection hole 66, and the step portion 64 is provided with a concave portion 641 for inserting the convex portion 15 provided at the rear end of the lock device 1. If the locking device 1 is provided with a fixing protrusion (not shown), a small recess 642 for inserting the protrusion may be formed. By fitting the convex portion 15 into the concave portion 641, the main body 10 is prevented from rotating, and it is possible to prevent the lock device 1 from being broken and broken by grasping the portion exposed from the door 90 and twisting it with an excessive force.

  Next, the lock device 1 will be described. As shown in FIG. 4, the locking device 1 has a cylindrical main body 10, and the rear side of the main body 10 is covered with the large-diameter portion 61 when the locking device 1 is attached to the base member 60. On the side surface that is covered with the large diameter portion 61 of the base member 60 of the main body 10, a protruding port 111 for exposing the detachable protrusion 17 is formed.

  A hole 112 for allowing the driver 18 to protrude from the rear end of the lock device 1 is formed at the rear end of the main body 10 with a diameter that allows the driver 18 to rotate. Further, around the hole 112, two convex portions 15 to be inserted into the concave portion 641 are formed.

The outer diameter of the lock device 1 is preferably substantially the same diameter as the cylinder lock installation hole 95 or the conventional cylinder lock, and specifically, the cylinder lock installation hole 95 provided in the existing door 90 Although it is formed in substantially the same 44 mm, it can be formed in a desired diameter or outer diameter. By making the outer diameter of the lock device 1 substantially the same as the cylinder lock installation hole 95, it is possible to use the base without trouble even in various doors 90 having different positions of the handle 96, the position of the cylinder lock, the hood width, and the like. The member 60 can be attached and detached.

  The locking device 1 includes an operating position for locking and unlocking the door lock, a locking and unlocking mechanism operated to a lock position where locking and unlocking are not possible, the detachable protrusion 17 and the detachable protrusion when the locking and unlocking mechanism is in the locked position. It has a locking mechanism that holds it impossible. The attaching / detaching protrusion 17 is formed in an arc shape so that the outer surface fits into the engaging groove 621, is rotatably attached to the stopper shaft 171, and is biased outward by the attaching / detaching spring 172 (FIGS. 7 and 9). reference). The locking / unlocking mechanism has a function of locking / unlocking the door lock at the operating position when the locking device 1 is incorporated into the base member 60, and the locking mechanism abuts on the inner surface of the detachable protrusion 17 during locking, and is attached / detached. Even if the protrusion 17 is pushed in the radial direction, it has a function of preventing intrusion into the inside.

  FIGS. 5 and 6 show the main part of an electronic locking device 1 as an embodiment of the locking and unlocking mechanism, and a thumb turn ring provided with an internal gear 51 as shown in FIG. 50 is pivotably incorporated. The thumb turn ring 50 has a cylindrical shape and is formed to a length that can partially cover the outer periphery of the main body 10. As shown in FIG. 6, a front protrusion 52 extending inward in the radial direction is formed on the inner surface of the thumb turn ring 50, and prevents the thumb turn ring 50 from coming off by contacting the main body 10 located in front. Yes. The internal gear 51 is formed on the inner surface behind the front protrusion 52. A ring washer 54 is fitted between a stepped portion 53 formed behind the internal gear 51 and a projection 114 of the main body storage portion 11 provided in the main body 10. Thereby, the thumb turn ring 50 can be stably rotated, and the annular fixing groove 16 (FIG. 4) into which a part of the tip side of the base member 60 can be inserted between the main body 10 and the thumb turn ring 50. Reference) is formed.

  In the main body 10, a connecting shaft 30 having a connecting gear 31 that engages with the thumb turn ring 50 at the front end and a connecting shaft 26 that can be engaged with the tail gear 19 at the rear shaft portion is inserted in an axially movable and non-rotatable manner. Is rotatably provided. The tail gear 19 is rotatably housed in the main body 10, and the driver 18 is fitted to the rear part. In addition, in order to hold the connecting gear 26 so as to be movable in the axial direction in a non-rotating state, a part of the connecting shaft 30 to which the connecting gear 26 is fitted is provided with a flat portion 32 on a cylindrical side surface and has an irregular cross section. Although formed, the portion into which the connecting gear 26 is inserted may be formed on the angular axis.

  The front end of the connecting shaft 30 is pivotally supported by the main body 10, and the rear end is pivotally supported by the convex portion 15 provided at the rear end end of the main body 10. A space that allows the movement of the connecting gear 26 to move relatively in the axial direction is formed in the convex portion 15. The connecting gear 26 is moved to a position where the connecting gear 26 is engaged with or disengaged from the tail gear 19 by a rotation interrupting mechanism.

  The rotation interrupting mechanism can have various configurations using an appropriate clutch mechanism or the like, but in this embodiment, a mechanism using an actuator such as a motor is used. In other words, the embodiment includes a motor 40 having a motor gear 41, a geared screw ring 21 rotated by the motor gear 41, and a screw shaft 22 moved in the axial direction by the geared screw ring 21. When 22 moves in the axial direction, the connecting gear 26 also moves. The screw ring 21 with gear and the screw shaft 22 are formed in a cylindrical shape so that the connecting shaft 30 can freely rotate. A control circuit 123 and a battery 70 are provided to rotate the motor 40 forward and backward.

  The control circuit 123 is configured to operate the motor 40 when an appropriate signal is received. This signal includes personal information based on user biometric information such as electronic information such as authentication codes recorded on electronic information media such as IC cards and smartphones, fingerprints, irises, voiceprints, retinas, veins, genes, facial contours, etc. Recognition information, input information using a numeric keypad, and other information can be selected as appropriate. As a receiving method, wireless non-contact communication or a wired line can be appropriately selected. In the embodiment shown in the figure, Bluetooth (registered trademark) communication is used, but it can also be operated by non-contact communication such as NFC (Near Field Communication) communication, other wireless communication, and infrared communication.

  The battery 70 may be any battery that can drive the lock device 1. For example, a cylindrical battery such as CR-123A can be suitably used. This battery is housed in a space provided along the longitudinal direction of the main body 10 in the main body housing portion 11 (see FIG. 6).

  The screw ring 21 with gears has a female screw portion 211 formed on the inner surface, and a gear portion 212 that engages with the motor gear 41 on the outer periphery (see FIG. 6). The screw ring with gear 21 shown in FIG. 6 has the female screw portion 211 and the gear portion 212 formed integrally in a cylindrical shape, but may be formed separately and then combined and fixed.

  The screw shaft 22 has a male screw portion 221 that engages with the female screw portion 211 of the geared screw ring 21 at its outer periphery, and when the geared screw ring 21 rotates, the male screw portion 221 and the female screw portion. It moves to the front or to the back by the screw engagement of 211 (see FIGS. 6, 8, and 10). The detachable protrusion 17 is provided adjacent to the screw shaft 22. A large-diameter portion 263 that can come into contact with the detachable protrusion 17 when the screw shaft 22 moves forward behind the male screw part 221, and the detachable protrusion 17 when the screw shaft 22 moves backward. A small-diameter portion 264 that can be opposed is provided. As shown in FIGS. 7 and 9, the large-diameter portion 263 and the small-diameter portion 264 are not allowed to enter the main body 10 when the large-diameter portion 263 contacts the detachable protrusion 17, and can be detached when facing the small-diameter portion 264. The diameters of the large-diameter portion 263 and the small-diameter portion 264 are determined so that the protrusion 17 can be immersed in the main body 10. In this embodiment, the small diameter portion 264 and the large diameter portion 263 form a locking mechanism.

  On the outer peripheral surface of the screw shaft 22, a non-rotating projection (not shown) provided on the main body 10 and a groove (not shown) engaged therewith are supported so as to be movable in the axial direction in a non-rotatable state. A magnet 224 is provided on the outer peripheral surface of the screw shaft 22 so that the sensor 115 can detect that it has moved to a predetermined position (see FIG. 5).

  Referring to FIG. 10, the connecting gear 26 provided at the rear end of the connecting shaft 30 is inserted into the rear end of the screw shaft 22 as shown in FIG. A fitting groove 223 is formed. A slide washer 24 is rotatably disposed in front of the inner peripheral surface of the screw shaft 22, and the screw shaft 22 and the connecting gear 26 are separated from each other between the slide washer 24 and the flange 261 of the connecting gear 26. A counter spring 25 is interposed so as to bias in the direction.

  With the above configuration, when the screw shaft 22 moves backward, the counter spring 25 is compressed, and the connecting gear 26 moves rearward and meshes with the tail gear 19 by the compression force of the counter spring 25 (see FIG. 6). In this state, as shown in FIG. 7, the small-diameter portion 264 of the screw shaft 22 has moved to a position facing the detachable protrusion 17 with a gap, so that the detachable protrusion 17 is moved to the engagement groove 621. You can immerse yourself until you get out of the way.

  From this state, when the screw shaft 22 is rotated in the reverse direction, the connecting gear 26 moves away from the tail gear 19 and moves to the disengaged position via the flange 261 and the retaining ring 23 as the screw shaft 22 moves forward. (See FIG. 8). In this state, as shown in FIG. 9, the large-diameter portion 263 has moved to a position facing the detachable protrusion 17, so that the detachable protrusion 17 cannot be immersed.

  Also, as shown in FIG. 10, when the connecting gear 26 moves backward, even if the tooth tip abuts against the tooth tip of the tail gear 19 and the movement stops, the screw shaft 22 moves as described above. Therefore, only the screw shaft 22 moves backward to a predetermined position. As a result, since the connecting gear 26 is biased rearward, when the thumb turn ring 50 is rotated and the connecting gear 26 is finely moved in such a state, the connecting gear 26 and the tail gear 19 are engaged. Can do.

  A rear end inclined surface 262 is formed on the rear end outer peripheral surface of the connecting gear 26 so that the connecting gear 26 and the tail gear 19 can be smoothly engaged, and a front end inclined surface 191 is formed on the front end outer peripheral surface of the tail gear 19. is there. The angle between the rear end inclined surface 262 and the front end inclined surface 191 can be appropriately set, but is preferably set at about 15 degrees as shown in FIG.

  The geared screw ring 21 and the motor gear 41 are housed in the gear box 14 and set in the main body 10. The positive terminal 122 that comes into contact with the control circuit 123 and the positive terminal of the battery 70 is installed on the plate-like main board 121.

  The main body 10 includes a main body storage portion 11 that stores a locking / unlocking mechanism, a motor 40, a battery 70, and the like, a substrate storage portion 12 that stores a main substrate 121 provided with a control circuit 123, and a storage lid portion 13. .

  The storage lid portion 13 has a disk shape, and is formed with a USB connection terminal exposing port 131 penetrating from the rear surface to the front surface so as to be connectable to the USB board 132 installed on the rear surface. The outer diameter of the storage lid portion 13 is substantially equal to or slightly larger than the outer diameter of the thumb turn ring 50 so that the front end of the thumb turn ring 50 abuts the rear surface of the storage lid portion 13. The USB board 132 is connected to the control circuit 123.

  The storage lid 13 is provided with an annular front cover 134 on the front surface and a plug cover 133 at the center thereof (see FIG. 6). Since the plug cover 133 has a cover that covers the USB connection terminal exposing port 131, the USB board 132 can be prevented from being exposed except when necessary. Further, when an impact is applied to the main body 10 by the front cover 134, the impact can be reduced.

  Thus, in the case where the locking / unlocking mechanism is the electronic locking device 1, it is necessary to house the motor 40, the electronic control circuit, and the battery 70 for driving them, but the structure is formed as described above. Thus, as with other types of locking devices, the outer diameter can be made substantially the same as that of the cylinder lock installation hole 95 or a conventional cylinder lock. As a result, the electronic locking device 1 is mounted in the same manner as the other various types of locking devices 1 even with various doors 90 having different positions of the handle 96, the position of the cylinder lock, the hook width and other aspects. Can be exchanged with each other.

  The use state of the locking device 1 and the base member 60 of the present invention will be described. When the control circuit 123 receives the identification information from electronic information from a Bluetooth communication device such as a smartphone, the motor 40 rotates and the screw shaft 22 rotates through the geared screw ring 21. By this rotation, the connecting gear 26 moves to the engagement position with the tail gear 19 and the locking / unlocking mechanism becomes the operating position. Then, by rotating the thumb turn ring 50, the rotation can be transmitted to the tail gear 19 via the connecting shaft 30 and the connecting gear 26.

  When the thumb turn ring 50 is manually rotated, the tail gear 19 can be rotated and unlocked via the driver 18. Moreover, if it rotates in a reverse direction, it can lock. In this state, the magnet 224 of the screw shaft 22 is recognized as being operable by being detected by the sensor 115, and electronic information such as a new authentication code can be registered.

  The driving of the motor 40 is controlled to stop after rotating for a predetermined time to move the connecting gear 26 to the non-engagement position, so that the locking / unlocking mechanism is in the lock position and thereafter the thumb turn ring 50. Even if is rotated, the tail gear 19 cannot be rotated, and unlocking from the outside becomes impossible. Further, since the connecting gear 26 and the tail gear 19 are not normally engaged with each other, even if the locking device 1 is destroyed, it can be unlocked by turning the thumb turn 97 from the inside of the room.

  Next, a method for attaching and detaching the lock device 1 of the present invention to the base member will be described. When the locking / unlocking mechanism is in the locked position, the attaching / detaching protrusion 17 of the locking device 1 contacts the large diameter portion 263 of the screw shaft 22 and does not enter the main body 10 as described above. . In this state, the screw shaft 22 has moved backward to a position where the detachable protrusion 17 can contact the small diameter portion 264. Therefore, the detachable protrusion 17 is inserted into the base member 60 while being pushed into the main body 10. Since the detachable protrusion 17 is biased outward, it can be easily engaged with the engagement groove 621. When the locking device 1 is attached in this manner, the driver 18 that protrudes rotatably from the proximal end of the locking device 1 engages with an interlocking member that operates a dead bolt or the like.

  When the locking device 1 is removed, the operating position is set in the same manner as in a normal use state, and the screw shaft 22 is moved backward so that the detachable protrusion 17 and the small diameter portion 264 can come into contact with each other. In this state, the lock device 1 can be separated from the base member 60 by inserting a pin into the removal hole 611, immersing the detachable protrusion 17 into the main body 10 and moving the lock device 1 forward.

  As described above, the lock device 1 is configured so that it can be attached to the base member 60 if it can be operated with a key that is normally used. Therefore, there is no need for a dedicated key for making the lock device 1 detachable, so there is no need to provide a dedicated key for each type of lock device 1. There is no problem that the number of types of keys increases, especially in a housing complex, and the management of keys becomes complicated.

  Further, if the lock device 1 is simply structured to be detachable from the base member 60, the lock device 1 may be exchanged with a third party other than the user. While the device 1 becomes unusable and the attached locking device may not be able to be removed, such a situation can be prevented.

  In the embodiments shown in FIGS. 5 to 10, the locking / unlocking mechanism is an electric type, but various types such as a cylinder type (cylinder lock), a card type, a magnetic type, and a code number type lock may be used as the type of lock. it can.

  In the above embodiment, the locking device having a screw shaft that moves in the axial direction between the operating position and the locking position is shown, but other locking devices can be used. For example, when the driver is driven by rotating the operating body between the operating position and the locking position, the configuration shown in FIG.

  The locking / unlocking mechanism of the locking device shown in FIG. 11 has an operating body 117 rotatably housed in a main body 10A, and a driver (not shown) is connected to the rear end of the operating body 117. When the locking / unlocking mechanism is in the operating position, the door lock can be locked / unlocked via the operating body 117 and the driver, and when in the locked position, the operating body 117 is held non-rotatable. An attaching / detaching protrusion 17 </ b> A is disposed adjacent to the operating body 117. The operating body 117 has a projecting surface 118 that is in sliding contact with the inner surface of the main body 10A and a flat surface 119 that creates a gap between the inner surface. Therefore, as shown in FIG. 11, when the locking / unlocking mechanism is in the locked position, the protrusion 118 of the detachable protrusion 17A abuts on the operating body 117 and cannot be immersed, but the locking / unlocking mechanism is in the operating position. In some cases, the attachment / detachment protrusion 17A can be immersed until the contact with the flat surface 119 of the operating body 117, and the lock device can be attached / detached from the base member.

  Further, in the case of a locking device that is operated to the operating position and the locking position by directly rotating the driver, it can be configured as shown in FIG. 12 as an example. FIG. 12 shows an embodiment applied to a cylinder-type locking device 1B. In the lock device 1B, an annular fixing groove 16B into which the front end of the large diameter portion 61 of the base member 60 can be inserted is formed in the main body 10B. An inner cylinder 80 that is connected to the driver 18B as a locking / unlocking mechanism and is rotated or non-rotated by a key is provided in the main body 10B.

  An attachment / detachment protrusion 17 </ b> B is provided in the main body 10. As shown in FIG. 13, the detachable protrusion 17 </ b> B is housed in a housing portion 113 adjacent to the inner cylinder 80, and the housing portion 113 has a projecting opening 111 </ b> B and an opening 141 that allows a stopper pin 27 to be described later to protrude and retract. The formed detachable protrusion 17B can be immersed inward until it is disengaged from the engaging groove 621 (see FIG. 13).

As a locking mechanism, a cylindrical joint cam 29 accommodated in the locking device 1B so as to be rotatable and non-movable in the axial direction while being prevented from rotating by the driver 18B, and the forward and backward direction by rotation of the joint cam 29 A cylindrical slide sleeve 28, a stopper pin 27 (see FIG. 13) that is inserted in a slidable manner in the slide sleeve 28 and faces the detachable protrusion 17 B (see FIG. 13), a stopper spring 283, and the front end of the stopper pin 27 Can protrude from the opening 141 as described above.

  As shown in FIG. 14, a braking groove 291 in which a projection 281 of a slide sleeve 28 to be described later can slide is formed on the side surface of the joint cam 29. The braking groove 291 is curved in the front-rear direction. The width of the front top 292 that is the top on the front side of the braking groove 291 and the width of the rear top 293 that is the top on the rear side is the distance that the slide sleeve 28 described later moves from the operating position to the locked position (or from the locked position to the operating position). The distance between the front top 292 and the rear top 293 is substantially equal to the rotation angle of the key during unlocking.

  As shown in FIG. 15, the slide sleeve 28 has a protrusion 281 that is inserted into the braking groove 291 of the joint cam 29 on a part of the side surface on the rear end side. The protrusion 281 is formed with a thickness that does not hinder the rotation of the joint cam 29. A stopper pin 27 is formed on the inner peripheral surface of the slide sleeve 28 so as to be movable in the axial direction.

  The stopper pin 27 has a contact portion 271 that protrudes into the accommodating portion 113 and faces the detachable protrusion 17B (see FIG. 13), and a column portion 273 having a smaller diameter than the contact portion 271, and the contact portion 271 and the column. The part 273 is connected via the step part 272 (refer FIG. 12). The rear side of the column part 273 is prevented from coming off by a retaining ring 275 with the stopper pin 27 protruding from the rear side of the slide sleeve 28.

  The stopper spring 283 has one end abutting against the step 282 in the slide sleeve 28 and the other end abutting against the step 272 of the stopper pin 27 to urge the stopper pin 27 and the slide sleeve 28 in the separating direction. . A space for allowing the slide sleeve 28 and the stopper pin 27 to move is formed in the convex portion 15B formed at the rear end of the locking device 1B in substantially the same manner as in the above embodiment.

  With such a configuration, when the locking device 1B is set to the operating position, the joint cam 29 rotates in conjunction with the rotation of the driver 18B, and the protrusion 281 of the slide sleeve 28 slides on the side surface of the braking groove 291 to the rear top 293. As a result, the slide sleeve 28 moves backward. As the slide sleeve 28 moves, the stopper pin 27 also moves rearward through the retaining ring 275. As a result, the detachable protrusion 17B does not face the contact portion 271 of the stopper pin 27. Thereby, the detachable protrusion 17B can be immersed inward.

  From this state, when the locking device 1B is set to the locked position, the joint cam 29 rotates in the reverse direction, and the projection 281 of the slide sleeve 28 slides on the side surface of the braking groove 291 to the front top 292, and the slide sleeve 28 moves forward. Moving. As the screw shaft 22 moves forward, the stopper pin 27 also moves forward, and the contact portion 271 faces the detachable protrusion 17B. As a result, the detachable protrusion 17B cannot be immersed.
