Description

  The present invention relates to a wire lock for securing a bicycle, baggage, or the like to a support structure such as a roadside tree.

  When bicycles, leisure equipment (camping equipment, surfboards, etc.), baggage goods, etc. are left unattended, these items need to be protected from theft. Particularly in bicycles, wire locks are widely used as a means for preventing theft. This wire lock generally includes a wire in which a plurality of steel wires are twisted and a lock body that opens and closes both ends of the wire with a key, a dial, or the like. By wrapping around the rear wheel etc. to regulate the rotation of the wheel, or by winding the part of the bicycle and the support structure such as the roadside tree integrally with the wire and fixing it with the lock body, by driving or taking away the bicycle Theft can be prevented.

  Examples of such wire locks for bicycles include: (1) a wire that is a long member that can be bent and has high rigidity against tension; a locking rod provided at one end of the wire; and a wire provided at the other end. In a two-wheeled vehicle lock that is formed in a loop shape with the lock rod and the lock body maintained in a locked state at the time of locking, the keyhole forming surface of the lock body and the lock rod 2. Description of the Related Art A two-wheeled vehicle lock has been developed in which a portion other than a locking portion between a lock body and a lock body is covered with soft rubber or the like (see Japanese Patent Application Laid-Open No. 2008-57197). (2) A wire provided with a lock body connected to one end of a flexible wire rope, and an engaging portion provided at the other end of the wire rope and detachably engaged with the lock body. A lock has been developed (see Japanese Patent Application Laid-Open No. 2005-67412). A flexible thin wire is wound around the wire rope of the wire lock in a coil shape. This thin wire has a loop portion at both ends, and a wire rope can be inserted into the loop portion.

  However, (1) the two-wheeled vehicle lock disclosed in Japanese Patent Application Laid-Open No. 2008-57197 has high rigidity although the wire itself can be bent, and it is difficult to bend and deform freely in a desired direction, and handling is difficult. There is an inconvenience that becomes difficult. In addition, since the shape of the wire is a simple loop shape and the length of the wire is limited to some extent, the location and pattern of attachment to each part of the bicycle are simplified, and as a result, one portion of the wire is cut. It can be unlocked only with the bicycle, and the bicycle is taken away and stolen. Further, (2) the wire lock disclosed in Japanese Patent Application Laid-Open No. 2005-67412 has a structure in which a thin flexible wire wound in a coil shape around a wire rope is developed and wound around a structure. Although it can be locked to an object, the structure of the wire lock is complicated, and there is an inconvenience that it is not easy to lock and remove the bicycle and the support structure.

JP 2008-57197 A JP-A-2005-67412

  The present invention has been made in view of these inconveniences, and it is possible to easily and reliably realize the connection and release of a pair of locking objects with a simple structure, and it is lightweight, compact and convenient to carry. The purpose is to provide a highly lockable wire lock.

The invention made to solve the above problems is
A wire lock comprising a lock body having a hook portion and controlling opening and closing of the hook portion, and a linear wire body having flexibility,
A loop portion is formed at one end of the wire body, and a lock body is connected to the other end.
A wire lock characterized in that the lock body can be inserted into a loop portion.

  The wire lock is mainly composed of a lock body and a wire body, and has a smart and simple structure in which a lock body is connected to one end of the wire body and a loop portion is formed at the other end. Since this wire body is a flexible linear member, it is highly flexible and can be easily bent and twisted. It can be wound and fixed to a locked object, and can be stored and compact when not in use. In handling such as crystallization, extremely high convenience can be exhibited.

  Specifically, since the lock body having the hook portion can be inserted into the loop portion of the wire body, after winding the wire body around one of the pair of lock objects, The wire lock and the pair of lock objects are inserted by various means such as inserting the lock body integrally and then winding the lock body around the other lock object and then hooking the hook portion to the wire body. Can be easily and securely attached and fixed.

  A normal wire lock can only connect a pair of locking objects at a distance of about half or less of the length of the wire body. However, according to the connection method described above, the wire lock can reduce the length of the wire body. It is possible to effectively use and connect a pair of locked objects at a relatively long distance. Further, the wire lock is wound relatively small from the loop portion of the wire main body, and finally the lock main body is inserted into the loop portion, so that the wire lock can be gathered in a compact manner, and the storage property, the portability, and the like are improved.

  As described above, the hook portion of the lock body may be hooked on the wire body. Since the hook portion of the lock body can be hooked to the wire body, the lock body can be hooked at an arbitrary position of the wire body in a state where the wire body is attached to the object to be locked. The locking object can be securely attached, and the attachment pattern can be complicated.

  The lock body may include a plurality of dials that control locking and unlocking. Since this lock body has a plurality of dials for controlling locking and unlocking, it is not necessary to prepare keys and keyholes, and locking and unlocking can be controlled only by the lock body, so handling and convenience of wire locks Will improve. In addition, since the lock body is a dial type, the members constituting the lock body can be reduced, and the lock body can be reduced in size and size. As a result, the lock body is looped on the wire body. It can be easily and smoothly inserted into the part.

  The wire body includes a core wire formed by twisting a plurality of steel wires, a strand spirally wound around the outer periphery of the core wire, and an interstitial material sandwiched between the core wire and the strand. The diameter of the circumscribed circle of the wire body is preferably 2 mm or more and 6 mm or less. The interstitial material is inserted between the core wire and the strand of the wire body, and the diameter of the circumscribed circle is adjusted to the above range, so that the flexibility of the wire body is improved and the wire body is easily attached. In addition, it is possible to effectively realize compact storage when not in use.

  The wire body may be an elastic body that does not have shape memory characteristics. Since this wire body is an elastic body that does not have shape memory characteristics, even when the wire body is deformed by applying a load such as bending or twisting, when the load is released, the shape at the time of deformation Can be easily restored to the original shape without memorizing and the convenience of handling can be further improved.

  The flexibility of the wire body is preferably 900 or more and 1500 or less. By setting the flexibility of the wire main body within the above range, the flexibility and bendability of the wire main body can be further improved, and as a result, the ease of handling can be significantly improved.

  The outer periphery of the wire body may be covered with a synthetic resin. By covering the outer periphery of the wire main body with the synthetic resin, it is possible to impart good durability, waterproofness and rust prevention in a well-balanced manner while ensuring flexibility and ease of handling of the wire main body.

  The wire lock can be suitably used as a bicycle wire lock. Bicycles are particularly easy to be stolen and their structure and shape are complicated. Therefore, by using the wire lock as a bicycle antitheft tool, the wire body can be easily and securely locked to objects such as bicycles and utility poles. It can be securely attached and fixed. Further, the anti-theft effect can be further improved by adjusting the number of times or the place where the wire body of the bicycle wire lock is attached and making the attachment pattern complicated.

  Here, the “diameter in the circumscribed circle of the wire main body” is a value based on “measurement of actual diameter” defined in JISG-3525. The “shape memory characteristic” means a characteristic of continuously maintaining the deformed shape when the wire body is deformed by bending or twisting. “Flexibility” is a scale for quantitatively displaying the flexibility of a wire rope, and means the ratio between the bending characteristics of a wire rope and a round steel bar of the same diameter and the bending characteristics of the wire rope.

  As described above, the wire lock of the present invention has a smart and simple structure, and can fix and lock a pair of objects to be locked with various attachment patterns by a simple operation. Moreover, since the wire lock of the present invention can be easily carried in a compact manner when not in use, it can be widely used particularly for theft prevention of bicycles, leisure goods, baggage goods and the like.

It is a side view showing one embodiment of a wire lock concerning the present invention. It is the side view which looked at the internal structure of the lock main body of the wire lock of FIG. 1 from one side. It is the side view which looked at the internal structure of the lock main body of the wire lock of FIG. 1 from the other side. It is typical sectional drawing of the wire main body of the wire lock of FIG. It is a schematic diagram which shows the state which adhered and fixed the wire lock of FIG. 1 to a pair of locking target object.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

  A wire lock 1 in FIG. 1 includes a lock body 2 and a wire body 3.

  The lock body 2 is a member for integrally fixing the object to be locked and the wire body 3 wound around the object to be locked by being hooked to the wire body 3. The lock body 2 includes a body portion 4, a hook portion 5, a gate portion 6 that controls opening and closing of the hook portion 5, and a locking / unlocking control mechanism that adjusts locking and unlocking of the hook portion 5 and the gate portion 6. 7 and a connecting portion 8 with the wire body 3 are mainly provided. The body portion 4 has a notch portion (window) for confirming a number written on the surface of the dial 15 described later.

  The hook portion 5 is a member that extends and curves integrally from the body portion 4 and can be hooked on the wire body 3. The tip projection 9 (not shown) of the hook portion 5 is slid and fitted into the tip recess 10 (not shown) of the gate portion 6 so that the hook portion 5 and the gate portion 6 are connected to each other and closed. As a result, the hooked wire body 3 can be prevented from being detached from the lock body 2.

  As shown in FIGS. 2 and 3, a part of the gate portion 6 is embedded in the body portion 4, and swings up and down around the pin 11 as a rotation axis. The swing of the gate portion 6 is interlocked with the elastic motion of the spring elastic body 12 that is attached to the pin 11 inside the body portion 4. When a part of the gate part 6 is pressed by the interlocking of the swinging of the gate part 6 and the elastic movement of the pin 11, the gate part 6 settles inside the body part 4 with the pin 11 as the rotation axis, and the pressure is released. Then, it jumps up from the inside of the body portion 4, and the tip recess portion 10 of the gate portion 6 is fitted to the tip protrusion portion 9 of the hook portion 5. Further, as will be described later, the gate 6 is integrally formed with a stopper 13 for preventing the gate 6 from swinging. The material of the pin 11 is not particularly limited, and examples thereof include metals such as shape memory alloys.

  The locking / unlocking control mechanism 7 adjusts the locking and unlocking of the lock body 2 by controlling the closing and opening of the hook portion 5 and the gate portion 6. Specifically, the lock control is to maintain the hook portion 5 and the gate portion 6 connected and closed, and the unlock control is to maintain the hook portion 5 and the gate portion 6 freely openable and closable. It is. The type of the locking / unlocking control mechanism 7 is not particularly limited, but is preferably a dial type having a plurality of dials. Since the locking / unlocking control mechanism 7 is a dial-type locking / unlocking control mechanism, it is not necessary to prepare a key or a keyhole, and handling and convenience of locking / unlocking are improved.

  The structure of the dial-type locking / unlocking control mechanism 7 will be described in detail. The dial-type locking / unlocking control mechanism 7 includes a shaft portion 14, a dial 15, a setting cam 16, a press contact as shown in FIGS. 2 and 3. Mainly includes a spring 17, a password setting cap 18, a lock plate 19, and a return spring (not shown). Further, the lock plate 19 includes a convex cam portion 20 and a stopper 21.

  The shaft portion 14 is a member that serves as a basis for fitting and arranging the dial 15, the setting cam 16, the pressure contact spring 17, and the code number setting cap 18. The shaft portion 14 has a substantially cylindrical shape, and three protruding at equal intervals inside the body portion 4.

  The dial 15 is a disk-shaped member that is provided with a center hole for inserting the shaft part 14 in the center part and is rotatable when the shaft part 14 is inserted into the center hole. The dial 15 has numbers 0 to 9 concentrically arranged at equal intervals on the front side. On the other hand, a circular concave portion (not shown) concentrically with the center hole is formed on the back surface side of the dial 15, and ten spherical surfaces corresponding to the numbers 0 to 9 are formed in the concave portion. A protrusion (not shown) is formed. Further, as will be described later, the center hole of the dial 15 is adjusted to a size that allows the password number setting cap 18 to be inserted.

  The setting cam 16 is a disk-shaped member having a diameter that fits loosely into a circular recess on the back side of the dial 15. The setting cam 16 has a central hole for inserting the shaft portion 14 in the central portion, and ten spherical concave portions (not shown) disposed at positions corresponding to the spherical protrusions on the back surface of the dial 15. A notch portion having a shape that is loosely fitted to the convex cam portion 20 of the lock plate 19 is formed. In addition, as will be described later, the center hole of the setting cam 16 is adjusted to such a size that the security code setting cap 18 cannot be inserted.

  The pressing spring 17 is a coil-like member that fits into the shaft portion 14 and presses the setting cam 16 from the back side without passing through the center hole of the setting cam 16. The pressure spring 17 is elastically brought into contact with the back surface of the setting cam 16 in a state of being fitted to the shaft portion 14, and the surface of the setting cam 16 is pressed into contact with the back surface recess of the dial 15. The protrusions can be loosely fitted into the spherical recesses on the setting cam 16 surface. In this manner, the dial 15 and the setting cam 16 can rotate integrally around the shaft portion 14 in a state where the spherical protrusion on the back surface of the dial 15 is loosely fitted in the spherical recess on the surface of the setting cam 16. .

  The code number setting cap 18 is a substantially cylindrical member having one end opened and the other end closed, and in a state where the dial 15, the setting cam 16, and the pressure contact spring 17 are fitted to the shaft portion 14, The shaft 15 is fitted from the upper part of the dial 15. The code number setting cap 18 can be inserted through the center hole of the dial 15, but cannot be inserted through the center hole of the setting cam 16. As a result, when the code number setting cap 18 is pressed, the code number setting cap 18 presses the surface of the setting cam 16 and the loose fit between the spherical protrusion on the back surface of the dial 15 and the spherical recess on the surface of the setting cam 16 is released. can do.

  The lock plate 19 and the return spring are members that are disposed at substantially the same height as the setting cam 16 inside the body portion 4. The lock plate 19 can be shifted in the arrangement direction of the three dials 15 and is urged in a direction along the arrangement direction of the dials 15 via a return spring. One end of the return spring is in elastic contact with the lock plate 19 and the other end is in elastic contact with the wall surface inside the body portion 4, thereby exerting a biasing force in the arrangement direction of the dials 15.

  The lock plate 19 is integrally formed with a convex cam portion 20 that protrudes in the direction in which the dials 15 are arranged. The convex cam portion 20 has a similar shape that can be loosely inserted into the notch portion of the setting cam 16. Further, as shown in FIG. 3, a stopper 21 is integrally formed on the lock plate 19 in a direction perpendicular to the arrangement direction of the dials 15.

  As described above, in the lock body 2, the members constituting the lock body 2 are configured in a compact and integrated manner, and the size of the lock body 2 can be significantly reduced. As a result, the lock body 2 can be easily and smoothly inserted through the loop portion 22 of the wire body 3 as described later. In addition, it does not specifically limit as a raw material of the said member which comprises the lock body 2, For example, metals, such as iron, ceramics, etc. are mentioned.

  The connecting portion 8 is a portion for connecting the lock body 2 and the wire body 3. The connecting portion 8 is formed by drilling a connecting hole in the body portion 4 at any location that does not hinder the functions of the gate portion 6 and the locking / unlocking control mechanism 7. The lock main body 2 and the wire main body 3 can be firmly connected by inserting and connecting the wire main body 3 to the connecting portion 8. The wire body 3 inserted and connected in the connecting portion 8 can employ a loop structure similar to the loop portion 22 described later.

  The wire body 3 is a linear wire having flexibility, and is a member for winding and locking a pair of locking objects. One end of the wire body 3 is connected to the lock body 2 described above, and a loop portion 22 is formed at the other end. The structure of the wire body 3 will be described in detail. As shown in FIG. 4, the wire body 3 is composed of one core wire 24 composed of a plurality of steel wires 23 and six strands composed of a plurality of steel wires 23. 25, and an interstitial material 26 sandwiched between the core wire 24 and the strand 25.

  The loop part 22 is a part for inserting the wire body 3 wound around a locking object such as a roadside tree or a utility pole. The structure of the loop portion 22 will be described in detail. One end of the wire body 3 extending in the longitudinal direction is refracted and curved, and the tip of the wire body 3 is fixed to the wire body 3 to form a loop. Since this loop part 22 can penetrate the lock main body 2 and the wire main body 3 integrally, the operation of attaching / detaching the wire main body 3 to / from the object to be locked becomes easy. In addition, about the area of the hollow part of this loop part 22, it is not specifically limited, What is necessary is just a certain area in which the lock main body 2 can be penetrated.

  The means for fixing the tip of the wire body 3 and the wire body 3 when forming the loop portion 22 is not particularly limited. For example, the contact portion between the tip of the wire body 3 and the wire body 3 is made of aluminum or the like. For example, the metal base tube is pressed and coated, and the periphery of the metal is further coated with a synthetic resin or the like. Thus, the strength and durability of the loop portion 22 are improved by covering the contact portion between the distal end portion of the wire body 3 and the wire body 3 with metal and synthetic resin, and the loop portion 22 is released or broken. Can be effectively prevented.

  The steel wire 23 is a minimum unit wire constituting the core wire 24 and the strand 25. The material of the steel wire 23 is not particularly limited. For example, a piano steel wire, a hard steel wire, a PC hard steel wire, an oil temper steel wire, a galvanized steel wire, a stainless steel wire, a titanium steel wire, and a titanium alloy steel wire. Among them, a piano steel wire having high allowable stress and high durability against repeated loads is preferable.

  The core wire 24 is formed by twisting a plurality of steel wires 23. The structure for twisting the core wires 24 is not particularly limited, and for example, six steel wires 23 may be twisted to one steel wire 23. Thus, by twisting the six steel wires 23 to one steel wire 23, the tensile strength and flexibility of the core wire 24 can be exerted in a well-balanced manner.

  The strand 25 is formed by twisting a plurality of steel wires 23, and is spirally wound around the outer periphery of the core wire 24. The stranding structure of the strand 25 is not particularly limited, and the flexibility of the strand 25 is improved by twisting six steel wires 23 to one steel wire 23 as in the case of the core wire 24 described above. can do. Moreover, while twisting six steel wires on one steel wire 23, nine steel wires 23 can be twisted around the steel wire 23 to form a two-layer structure. Thus, by making the steel wire 23 which comprises the strand 25 into 2 layer structure, the softness | flexibility and non-rotation property of the strand 25 can be exhibited with sufficient balance. In addition, the number of strands 25 wound around the core wire 24 is not particularly limited. However, in order to impart good flexibility and impact resistance to the wire body 3, it is preferable that the number of strands is 6 strands.

  The core wire 24 and the strand 25 can be twisted only from the steel wire 23, but as the type of the steel wire 23, fibers other than the steel wire, for example, carbon fiber, aramid fiber, boron fiber, glass fiber, etc. are 1 A single species or a combination of two or more species can be twisted together.

  The interstitial material 26 is a member that is sandwiched between the core wire 24 and the strand 25 wound around the outer periphery of the core wire 24 and imparts good flexibility to the wire body 3. Examples of the material of the interstitial material 26 include natural fibers, synthetic fibers, natural fibers or synthetic fibers impregnated with lubricating oil, thermoplastic resins, and the like.

  Examples of the natural fiber include cotton, silk, wool, hemp, and pulp. Examples of the synthetic fiber include nylon fiber, polyethylene fiber, polypropylene fiber, polystyrene fiber, polyester fiber, polyamide fiber, acrylic fiber, polyvinyl alcohol fiber, polyethylene terephthalate fiber, urethane fiber, acrylic fiber, and ethylene vinyl acetate fiber. . Especially, it is preferable to employ | adopt the polyethylene fiber which can exhibit a softness | flexibility and durability with sufficient balance. In addition, as the lubricating oil, for example, mineral, animal and vegetable oils can be used alone or in combination of two or more.

  Examples of the thermoplastic resin include polyethylene, high density polyethylene, medium density polyethylene, low density polyethylene, polypropylene, ethylene-propylene copolymer, ethylene vinyl acetate copolymer, polyvinyl chloride, polyvinylidene chloride, polystyrene, and polyacetic acid. Vinyl, polytetrafluoroethylene, acrylonitrile butadiene styrene resin, acrylic resin, polyamide, nylon, polyacetal, polycarbonate, modified polyphenylene ether, polybutylene terephthalate, polyethylene terephthalate, glass fiber reinforced polyethylene terephthalate, cyclic polyolefin, polyphenylene sulfide, polytetrafluoro Ethylene, polysulfone, polyethersulfone, amorphous polyarylate, polyetherether Ketones, thermoplastic polyimide, polyamideimide, and the like. Among these, it is preferable to employ polyethylene that exhibits good flexibility, is easily available, and can be reduced in cost.

  The diameter of the circumscribed circle of the wire body 3 is preferably 2 mm or more and 6 mm or less, and more preferably 2.5 mm or more and 3.5 mm or less. By setting the diameter of the circumscribed circle of the wire body 3 within the above range, the flexibility of the wire body 3 is improved, and the wire body 3 is easily wound and deformed. Further, by improving the flexibility of the wire body 3, the wire body 3 can be gathered and compacted easily when the wire lock 1 is not used. In addition, if the diameter of the circumscribed circle of the wire body 3 is less than 2 mm, the flexibility of the wire body 3 is improved, but the tensile strength and durability are remarkably lowered. Further, if the diameter of the circumscribed circle of the wire main body 3 exceeds 6 mm, the flexibility of the wire main body 3 is reduced, the convenience of handling is reduced, and the wire main body 3 is increased in size and difficult to be made compact. Therefore, it is not preferable.

  The wire body 3 is an elastic body that does not have shape memory characteristics. Thus, since the wire body 3 does not have shape memory characteristics and is an elastic body, even when the wire body 3 is deformed by applying a load such as bending or twisting, the load is released. Unless there is a special circumstance such as newly applying a load from the outside, the original shape (a linear shape extending in the longitudinal direction) can be easily restored without memorizing the shape at the time of deformation. As a result, the wire body 3 can be freely bent and twisted in all directions in three dimensions, and can be easily applied to locked objects (bicycles, street trees, etc.) having a complicated surface shape and many irregularities. Can be worn.

The flexibility (flexibility number) of the wire body 3 is preferably 900 or more and 1500 or less, and more preferably 1200 or more and 1400 or less. The flexibility of the wire body 3 is a measure representing the ease of bending of the wire rope. The flexibility is F, the longitudinal elastic modulus of the steel rod is E, the bending stiffness elastic modulus of the wire rope is E _f , the cross-sectional secondary moment of the round bar having the same outer diameter as the wire rope is I, and the cross-sectional secondary moment of the wire rope is Is I _r , the flexibility F is calculated by the following mathematical formula (1). The flexibility F of the wire rope calculated in this way can be quantitatively shown on the basis of the flexibility F = 1 of the round steel bar, and means that a wire rope having a larger F value is easier to bend. By setting the flexibility of the wire main body 3 in the above range, the flexibility and ease of bending of the wire main body 3 can be improved, and the ease of handling can be significantly improved. If the flexibility of the wire body 3 is less than 900, the flexibility and bendability of the wire body 3 are lowered, and the ease of handling is lowered, which is not preferable. Further, if the flexibility of the wire body 3 exceeds 1500, the wire body 3 becomes excessively soft, and breakage / breakage due to bending stress tends to occur, which is not preferable.
F = (E * I) / (E _f * I _r ) ... number (1)

  The length of the wire body 3 is not particularly limited. For example, the length of the wire body 3 can be 3 m or more and 5 m or less. By setting the length of the wire body to 3 m or more and 5 m or less, the wire body 3 can be sufficiently wound and attached even when the shape of the lock target is large and complicated. Moreover, the length of the wire main body 3 can also be 1.5 m or more and 2 m or less. By making the length of the wire body 3 1.5 m or more and 2 m or less, it is possible to easily realize compactness by winding when not in use. The length of the wire body 3 means the length of the portion that does not include the connecting portion 8 and the loop portion 22.

  The outer periphery of the wire body 3 may be covered with a synthetic resin layer 27. As described above, the outer periphery of the wire body 3 is coated with the synthetic resin, so that the wire body 3 is provided with good durability, waterproofness, and rust prevention in a well-balanced manner while ensuring flexibility and easy handling. can do.

  The material of the synthetic resin layer 27 is not particularly limited. For example, polyurethane, nylon elastomer, polyether block amide, polyethylene, polypropylene, polyvinyl chloride, polyamide, polystyrene, fluorine resin, silicone resin, vinyl acetate, etc. Species can be used alone or in combination of two or more. Among these, it is preferable to employ polyvinyl chloride that exhibits good flexibility and is easily available. The color of the synthetic resin layer 27 is not particularly limited, and a visually conspicuous color such as a fluorescent color is preferable in consideration of the design effect and the security enhancement.

  Next, the usage method of the wire lock 1 is demonstrated.

<Locking / unlocking method of lock body 2>
A combination of numbers of the three dials 15 is displayed in the window of the body portion 4 described above, and this combination of numbers corresponds to a password code (initial code, release code) described in detail below. Before the password code is set in the lock body 2 (initial state), the initial code is set to “000”. In this initial state, the notches of the three setting cams 16 are oriented in the same direction, and the notches and the convex cam part 20 are all loosely fitted, whereby the stopper 13 and the lock plate 19 of the gate part 6 are loosely fitted. The stopper 21 is kept from colliding. In this initial state, the spherical projection on the back surface of the dial 15 and the spherical recess on the surface of the setting cam 16 are loosely fitted.

  In the initial state, when the personal identification number setting cap 18 of the locking / unlocking control mechanism 7 is pressed, the dial 15 is rotatable, but the setting cam 16 is prevented from rotating. When the dial 15 is rotated while the PIN number setting cap 18 is pressed, the spherical protrusion of the dial 15 is detached from the spherical recess of the setting cam 16, and only the dial 15 rotates while leaving the setting cam 16. To do. When an arbitrary opening code (for example, “329”) is set from the initial code “000” by the rotation operation of the dial 15 as described above, when the operation is stopped and the press of the password setting cap 18 is released, the pressure contact spring Due to the urging force of 17, the spherical protrusion of the dial 15 and the spherical concave portion of the setting cam 16 are loosely fitted again, and the dial 15 and the setting cam 16 are integrated. Accordingly, when the three cords 15 are set to the opening cord in the state where the opening cord is set, the notch portions of the setting cam 16 face the same direction, and the notch portions and the convex cam portion 20 are all loosely fitted. . In this state, even if the dial 15 is set to “000” again, notches of the setting cam 16 do not all face in the same direction.

  As described above, when the three dials 15 are aligned with the opening cord, the notch portions of the setting cam 16 are oriented in the same direction, and the notch portions and the convex cam portion 20 are all loosely fitted. The stopper 13 and the stopper 21 of the lock plate 19 do not collide. As a result, when a part of the gate portion 6 is pressed, the gate portion 6 swings inside the body portion 4 with the pin 11 as the rotation axis, The connection between the gate part 6 and the hook part 5 is released. Therefore, by pressing a part of the gate 6 to create a gap between the gate portion 6 and the hook portion 5 and inserting the wire body 3 into the gap, the lock body 2 can be hooked onto the wire body 3. To do.

  On the other hand, when the release cord is released by rotating the three dials 15 at random, all or a part of the loose fit in the notch portion of the setting cam 16 and the convex cam portion 20 of the lock plate 19 is released. The convex cam portion 20 of the plate 19 rides over the notch portion of the setting cam 16. Then, the lock plate 19 is shifted by the urging force of the return spring, and the stopper 13 of the gate portion 6 and the stopper 21 of the lock plate 19 collide with each other. And the state (locked state) to which the gate part 6 was connected can be maintained.
