Abstract

A cylinder for locks, adapted to be mounted to a lock body, has an outer cylinder which serves as a housing. A first inner cylinder, into which an electronic key is inserted, and a second inner cylinder adapted to be connected to a locking and unlocking mechanism of the lock body are rotatably provided in the outer cylinder. A connecting pin is retractably held by the first inner cylinder, and serves to connect the first inner cylinder and the second inner cylinder to each other when it advances. In the case where a proper key is inserted, a connecting pin controlling mechanism advances the connecting pin to mechanically keep the advancing state of the connecting pin, and in the case where the key is pulled out, the connecting pin is retracted by the connecting pin controlling mechanism. The connecting pin controlling mechanism has a cam plate which abuts against a projection of the connecting pin. When the cam plate inclines, the connecting pin is retracted, and when a cam member is made upright, the connecting pin is advanced.

Description

Damage to specification Name of invention

TECHNICAL FIELD The present invention relates to an electric lock cylinder mounted on a lock body. 2. Description of the Related Art A lock device is composed of a key and a lock. In recent years, high security locks have become popular. In such an electric lock device, the air-driven Ikimae River cylinder is connected to a lock release mechanism. An electronic circuit for identifying the electronic key is provided in the cylinder, and when an appropriate electronic key is inserted into the cylinder and the key is rotated, the operation of the Afe lock or unlocking operation is performed. It can be carried out.

The power of a conventional electric lock device using such a cylinder is disclosed, for example, in Japanese Patent Publication No. Hei 6-1380000. In this conventional example, the lock lock cylinder is provided with an outer cylinder attached to the main suspension and a rotating cylinder inside the outer cylinder, which is connected to a lock release machine *. An inner cylinder, a bottle for which rotation of the inner cylinder is prohibited in the outer cylinder, and only when the appropriate key is inserted in the same 4 L, the bin is driven to remove the pin from the inner cylinder. And an electric driving means that allows free rotation of the inner cylinder. In such a configuration, if a suitable key is inserted into the keyhole of the inner cylinder, the bottle is released from the inner cylinder, and then the key is rotated to perform the locking or unlocking operation.

In this conventional electric cylinder, the operation of the inner cylinder was restrained by the pin and the pin, so a hard metal in the keyhole of the inner cylinder 厲, — ( Driver) It was not impossible to break the pin and unlock the lock by forcibly turning the inner cylinder. For this reason, there was a problem in safety.

In addition, for electric cylinders that are supplied with electric power from a battery or the like, there is a demand for minimizing the lightning power consumption when driving the pins in order to extend the life of the battery. In the past, it was difficult to reduce power consumption while ensuring reliable operation of the pins.

It should be noted that there is no complicated mechanical connection between the frosted key and the electric cylinder in the conventional electric lock device as seen in the relationship between the mechanical cylinder and the key and lock in the device. In a conventional electric cylinder, the inner cylinder stands up one time! For, the electronic key could be pulled out of the keyhole. For this reason, there was a problem that the rotational positional relationship between the inner cylinder and the outer cylinder (in a case where the state was not proper; ^), the movement of the bins could not be confirmed. In other words, the key was often pulled out or inserted from the keyhole in a state in which the bin and the hole were not positioned properly. In the Sakaki machine connected to the cylinder, the operation can be performed in the Sakaki machine, and if the above improper state occurs, the key will be inserted after the electronic key is inserted. The operating force required to find the position for performing the solution * solution ^ was required, and was extremely inconvenient.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problem, and has as its object to provide a pneumatic lock cylinder having excellent 3li protection and high ii resistance.

Another object of the present invention is to provide an electric lock-lock cylinder that can move a connecting pin as a window and can reduce power consumption.

In addition, the purpose of the present invention is to maintain the forward state of the connected bin and to perform the post-operation of the connected bin without requiring an electric driving force. Providing cylinders for

Another object of the present invention is to provide an electric power cylinder that can be used for controlling a connecting pin by performing a key operation (extracting a key from a key).

Another object of the present invention is to provide an electric Tagawa cylinder with good operability in which the key can be inserted only when the inner cylinder force is less than the proper rotational position. In order to achieve the above object, the present invention relates to a lock lock cylinder attached to a ftfij regular holiday, comprising: an outer cylinder; a rotatably provided inside the outer cylinder; An inner cylinder, a second inner cylinder rotatably provided in the outer cylinder and coupled to the lock * which is unlocked by the lock tree rest, and a second inner cylinder coupled to the unlocking mechanism; When the connection bin is moved forward, the connection bin for adjusting the inner cylinder of the first cylinder and the second cylinder is advanced, and the connection bin is advanced to a platform having an appropriate key force. And a connection bin control mechanism for mechanically holding the forward state of the connection bin, and for moving the connection bin behind a keying / pulling force. In the above, the outer cylinder is in contact with the housing of the lock lock cylinder, and the width of the outer cylinder is the first inner cylinder having a keyhole into which the key is inserted. The inner cylinder connected to the demolition machine and the inner cylinder and the power are combined. The inner part of i and the second part are connected by a connection bin. The inner cylinder desirably has a recess into which the front end of the front and rear connection bins is inserted.

If the two inner cylinders are rotated << in the connected state, the second inner

It takes a rest with one and repeats f. Thereby, or the unlocking force << is performed. On the other hand, in the state where the connection bin force << retreats, even if the first inner cylinder force ^ Ifc is applied, the inner cylinder of Π only idles and the second inner cylinder does not rotate.

The connection pin control is controlled by the connection pin controller. The connection bin control mechanism includes a first function (Π; Η ί glue function) for moving the connection pin forward, and a second function (latch function) for mechanically maintaining the forward state. , The said i-bin And a third function (retreat control function) for reversing.

It is advantageous in terms of torque if the direction of the connection pin is orthogonal to the rotation directions of the first and second inner cylinders. Conversely, if the retreating direction of the connecting bin is made parallel to the rotation fill direction of the first and second inner cylinders, the key insertion / removal motion can be directly transmitted to the connecting pin, that is, the driving force is transmitted. Ff? S can be converted to

In a preferred embodiment of the present invention, the apparatus further includes a key recognition circuit that identifies the inserted key and outputs a drive signal to a stage that is determined to be appropriate. In the above configuration, the key identification circuit is preferably composed of an electronic circuit, and transmits and receives data with [¾] to the inserted electronic key to determine whether the electronic key is appropriate or not. . In a preferred embodiment of the present invention, the connection bin controller includes: an urging member that applies a retreating force to the front bin; a protrusion fixed to the connection pin; In the inclined state, the null self-projecting portion is set to the rear; stable erection, and in the upright state, the cam plate for holding the projection in the forward stable position, and the front ilci driving signal are supplied. And actuating to generate a driving force for changing the force plate from the inclined state to the upright state.

In the above configuration, the biasing unit applies i: j force to the connection bin in the backward direction. For this reason, in normal operation, the link pin is in the last position (rear stable state), and even if the first inner cylinder rotates, its rotation is transmitted to the second inner cylinder. Don't let it go, just spin. Here, the urging portion is preferably formed of a temporary panel, one end of the temporary panel is fixed, and the other end pushes the projection force toward the self-retreating direction. The protrusion is desirably formed of a screw (stu ()) having a rotating existing roller.

Activate the actu Yue, When the posture of the cam plate is changed from the inclined state to the upright state by the rotation, the protrusion moves forward, and the tip force of the connecting pin << the second inner cylinder is fitted. At this time, the force for moving the protrusion forward (in other words, the rotational force of the cam plate) must be greater than the rear urging force of the urging unit. When the cam plate force is << completely upright, the projections are latched by the cam plate, and a stable state (forward stable and stable state) force is established. After that, even if the supply of the driving force to the cam plate is stopped, the connection pins are not naturally retracted, and the connection state of the two inner cylinders is maintained. In a preferred aspect of the present invention, the cam temporary is formed at an inclined surface where the projection fci portion is formed, and at a position S where the projection portion is lifted up by the force of the inclination, and latches the projection portion. And a recess. In a preferred aspect of the present invention, ; 連ピン制 ^ ^ ¾ 仮マグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグマグ; マグマグ己己 ^ 己己.

In other words, in order to build a stable forward state, electric work, mechanical 電気 π river, magnetic work

It is necessary to maintain the upright state of the cam plate by using JH. For the latching of the cam, it is desirable to apply a projection force to the apex portion of the cam plate; a 'force to form a depressed I 丄 i | portion', or a magnetic force of the magnet; Thereby, strength can be achieved.

In the above configuration, when the key force is pressed by the keyhole of the second inner cylinder, a part or all of the lip force is accumulated in the accumulation means. On the other hand, the key strength; In this case, the accumulated force is used by the latch release mechanism to cause the cam plate to fall from the upright state to the upright state. That is, the latched state is forcibly reset. In a preferred aspect of the present invention, the latch release mechanism further comprises: an arm that pushes down the temporary cam; and, when the key is inserted, converts the key input ILJ into a retracting motion of the arm. A key interlocking mechanism that, when the key is withdrawn, uses the accumulated force to convert the key's withdrawal movement to the arm's upright position.

According to the above configuration, when the key is inserted, the arm is moved away from the temporary cam, so that the force required to advance the connecting pin can be reduced. As a result, fg savings can be achieved, and downsizing can be achieved. When the key is pulled out, the arm can be driven by using the accumulated power in Icheon, which also saves power. In a preferred aspect of the present invention, the connection pin controller fit includes: a drive signal for generating a driving force for advancing a connection pin; Sometimes, the connecting pin is allowed to move forward, and when the key is pulled, when the key is ashed, the key pulling operation is transmitted to the connecting pin so that the connecting pin is moved backward, so that the key connecting device is moved backward.

Preferred Embodiment of the Invention FIG. 1 is a pictorial view of a lock river cylinder according to the present invention. The lock cylinder 1 includes a cylindrical outer cylinder 10 fixed to the lock body and a first cylindrical inner cylinder supported by [ΰpromotion I '; 1 4 (Second rotating part t) and {¾ 16 (Second rotating part) in node 2 and a: Inner circumference 1 2 of outer cylinder 10 and 筇: Inner cylinder 1 of I 4 and 2

One / ― A small gap exists between the outer peripheral surface of the inner cylinder 16 and the inner cylinder 16, and the gap IJ has a grease force. This effectively prevents water droplets and dust from entering the interior due to the gap.

At the end of the first inner cylinder 14, a panel portion 22 is formed; the key hole 20 into which the electronic key 18 is inserted is formed in the panel portion 22. The cap portion 30 has one end 28 of the outer cylinder 1◦. The 綠 portion 24 of the panel portion 22 is sandwiched between the outer end 2D 26 of the outer il 0 and the ¾0S of the cab H 30. As a result, the first inner cylinder 14 is in the rotation “J”, but has the moving force in the rotation direction;

On the other hand, the inner cylinder 16 of ^{No. 2} is formed as a bottom f ¹ rest in the present embodiment. The second inner til 6 is sandwiched between the other force end 4 at m I () and the end of the first inner cylinder 14, Is stored in the outer cylinder 10. Therefore, the cylinder 16 of the section 2 has the same force as that of ^ 14 in 笫: I; 2 and 3, the finger key 18 is formed in a temporary shape in this embodiment, and a small battery B and a g battery BT are provided in the holding portion 18A thereof. The signal generation circuit SC, which operates in response to the force ί! ¹ : ^, and the force «built-in. The signal generation SC is a circuit that outputs the code of this electronic key lock. The signal I, "The signal is provided to the transmission coil TC incorporated in the plug-in part 18B and is transmitted from the transmission coil TC. This is a known tft component ( For example, see FIG. 3 in Japanese Patent Application No. 62-280083.) In FIG. 4, a link hole 20 is formed in the panel portion 22. The il hole 20 is provided with an electronic key 18 insertion hole 18B. When the electronic key 18 is completely inserted into the keyhole 20, the electronic key 18 and the inner cylinder 14 of the section] rotate once, and both of them rotate. '1ί; ί Standing relationship does not shift. The member 30 is also provided with a keyhole 42 as a key guiding means. Only in the case where the angle of rotation of the keyhole 42 and the rotation angle and the force of the keyhole 20 match, the insertion of the electronic key 18 into the keyhole is allowed.

In this embodiment, a projection 18C is formed on the insertion portion 18B of the electronic key 18 (see FIG. 2), and the keyhole 42 is provided at the tip i W of the insertion portion 18B. A hole 42 A having an equal diameter and a cut 42 B having a length equal to the height H of the projection 18 C and having a width allowing passage of the projection 18 C are formed. ft In the child key 18, a gap portion 18 D force ′ is provided between the grip portion 18 Λ and the convex portion 18 C, and the thickness thereof is the thickness T of the cap portion H 30 (FIG. 1). Ii), and its length is G. Therefore, as can be seen from FIG. 1 and FIG. 4, only ^ in the 1 回 4 of the 1 ^¾ 'predetermined times M (force with the keyhole 20 and the keyhole 4 2; 问 dislocation 问' that matches) That is, only at 埸 / ^ at the turning position shown by the solid line in FIG. 4, the force that the convex 8 C passes through the keyhole 42 can be obtained. For this reason, insert the child key 18 into the keyhole 20 only when the rotation position of the outer cylinder 1 、 and 筇 1 內] 4 《 The electronic key 18 can be pulled out.

fg child key 18 force Insert the key hole 20 until the part 18 E of the gripping part 18 A contacts the cap part ^ 30, and the convex part 18 C Place it inside (see Figure 1). For this reason, the cap portion M3 () does not hinder the M 'movement of the end key 18 and the electronic key 18 makes it possible to li> |' In this case ^, as can be seen from Fig. 4, when ϋ¾ ΐ 4 of section】 is shifted from the position indicated by the actual position ^, for example, I にIn Yuni, the projection 18 C of the electronic key 18 gets caught on the surface of the cap W 30, and the end-key 18 cannot be inserted through the keyhole 42. This key 1, the end key 18 must be in the same way as the notch 4 2 位 and the keyhole 20, and the key is inserted / removed only at the matching position, and when the fg child key 18 is removed, The positional relationship between the inner cylinder 14 and the outer cylinder 10 can be set to a predetermined state.

Note that, despite the gluing of the keyholes 42, the keyholes 20 and 铋 holes 4 2 When the discrepancy is found, the driver '<etc. is inserted into the keyhole 20 via the keyhole 42, and the first inner cylinder 14 is rotated to solve such a mismatched state. 'Π I can. Of course, only the first inner cylinder 14 is rotated on the spot, and the rotation is not transmitted to the second inner cylinder 16. In FIG. 1, a connecting unit 44 for connecting the first inner Hi 14 and the second inner node 16 to each other is provided in the inner cylinder 14 of the first unit. The coupling unit 44 includes an electromagnetic rotary actuator 46 that operates in response to a frost signal, and a machine 48 that is extinguished by the rotary actuator 46. , Become. Here, the connection unit 44 includes a number f that controls the movement of a connection pin 54 described later. First, the configuration of Rotary Actuary 46 will be described with reference to FIG. The low-temperature reactor 46 has a cylindrical housing 46 with a pair of permanent magnets ί 6 46 Λ, 46 と and a trfi And a rotation output sleeve 46E fixed to the rotation output sleeve 46I). The housing 46C is fixed to the first liTj14 by screwing. The winding 46E is provided with a winding 46F. When! 51 dynamic flow is caused to flow through the ^ line 46F, the rotor 46E performs QK'i. The trochanter 46 is positioned at the position indicated by the X-X line or the の -Υ line in the figure “)”.

In Fig. I, the cap 6J is a part for preventing water droplets, dust, and the like from invading the inside through receiving the rotation output 46D. The cap section M46J is fixed to the housing 46C by means such as spot welding or screwing. Next, referring to Fig. 6, we explain M (Shina power;

The connecting mechanism 48 includes a connecting pin 54. The connection bin 54 is supported and guided by a pair of support guide rests 50 and 52 provided on the housing 46C. As a result, the pin 54 is at 1; I. It's in the 54th bin A long hole 56 is formed, and a rotation output 帕 46 D is passed through the long hole 56. At the tip of the rotation output 1itj46D, a cam plate 58 is fixed to the ISI by screwing or the like.

The connection bin 54 is provided with a stud 62 for holding a roller 60 rotatably. — The housing 64C has a stud 64 force <K; | L, and the stud 64 has one end of a leaf spring 66 as a retraction urging means fixed thereto. The other end of the temporary spring 66 urges the stud 62 toward the cam 58 opposite the cam 58. As a result, the connecting pin 54 is always urged in the retreating direction, and the connecting pin 54 is stopped at a position where the roller 60 taps the cam temporary 58 (that is, at the retreat-side stable position). Thus, since the connecting pin 54 is urged in the backward direction to ¹ I, the connecting pin 54 does not advance inadvertently due to vibration or the like.

In this stable state, the distal end 54 A of the connecting pin “> 4” is located at the position shown by the solid line in FIG. 6, and the first inner part 14 and the second inner part 16 are not connected. However, even if the first inner cylinder 14 is repeatedly turned, the first fi is not reached to the inner cylinder of I 2: I 6. (Refer to Fig. 1 and Fig. 6.) This recess 54A is a non-penetrating hole. When 駙. J 'flow flows through' ', the output 粬 46 D force <counterclockwise, turn in 11 directions (see Fig. 6), and in conjunction with this, the cam temporary 58 force The coupling-pin 54 is moved forward, whereby its tip 郞 54 Λ force enters the recess 16 前. Before this ϋ 则 the stable state is shown by the two-dotted line in FIG. J! While working on the cam plate 5 8 It will be described in detail.

When the cam plate 58 is in an inclined state (reset state), that is, when the first I person 4 and the second inner cylinder 6 are in force; Reference numeral 58 denotes a position indicated by a solid line in FIG. That is, the roller 60 is urged by the panel panel 66 to the temporary cam 58 °. When the drive flow is supplied to the rotary actuator 46, The rotation output # 46D rotates counterclockwise in FIG. 7, and the slide 62 with the roller 60 is pushed in the forward direction against the spring force of the leaf spring 66. Due to such a change in the posture of the cam plate 58, that is, a change from the inclined state to the upright state, the connection pin 54 having the stud 62 <1 moves forward. Then, the leading end 54 A enters the recess 16 A. At the tip (the ffi point) of the cam plate 58, a recess 58 for receiving the roller 6 is formed. The roller 60 side of the cam temporary 58 has a function as a slope on which the roller 60 rolls. Rho Yui Lactiyue 46, IJ Department 58 Λ, Laura 60 Force 《Until it is accepted, Cam tent 58 is [ΰΗί; When the temporary cam 58 is in the upright state, the supply of power to the Rotary actuator is stopped. This ^, the tip 54 of the pin 54 54 Force: dent 16 It becomes prone to crouch into the Λ. When the roller 6◦ is fitted into the recess 58A, the roller 6◦ cannot exit the recess 58 naturally due to the river Oo-Sakugawa, which is nodged. In other words, roller 60 is searched for iili in section 58A, and a stable forward state is established by mechanical Sakugawa. This latch state force is shown by a two-dot chain line in FIG.

In this state, the connection pin 54 is connected to the inner tube of the first] and the inner tube of the second] by a connecting pin 54 times; The second 16 of the elbows can be turned. FIG. 8 shows a state in which the lock ffl cylinder 1 is tied to a door lock rod. The outer cylinder 1 鈹 is fixed to the main body 100. The second pin 6 has a projection 16 formed thereon. The protruding piece 16 Β is connected to an unlocking machine drawing 104 for inserting and removing the bolt I, 102 of the main lock 100. Therefore, an appropriate key 1 18 is inserted into the inner cylinder 14 of ΓΠ, and the inner cylinder 14 is connected by the connecting machine ^ 48 of the first i 14 and the second 16 16 After that, the? S child key :! By turning 8, the second inner cylinder 16 rotates, and the operation of ίί¾locking / disintegration can be performed. That is, the conventional As in the case of the pin tumbler tablet, it is possible to take out the bolt 102. In FIG. 8, 106 is a thumb turn, 108 is a latch, and] 10 is a grip. Next, the latch release mechanism 68 for releasing the above-mentioned connection state will be described with reference to FIGS.

The release mechanism 68 includes a piano wire 72 (see FIG. 1 I 0 and a rod 74) which is a linear spring part. The base end 72 A of the piano wire 72 is a housing 46 C It is held at the threshold 70. The Ikawabata 7 2B of the piano wire 72 swings in conjunction with the insertion and removal of the TE-OK-key 18. At this time, the piano wire 72 is deformed raw, and the input of the child key 18 is stored as a sex deformation of the piano wire 72. The mouth 74 is provided with a rotary output line 46D and a housing. It is supported by 46 C. One end of the mouth 74 is connected to the end of the piano wire 72 / the end 72 B. The other end of the rod 74 is a submarine groove 74 A A guide bin 76 of a guide 76 is inserted into the sub-line ^ 74. The guide 76 is fixed to the housing 46C.

With this configuration, the rotation of the rod 74 is restricted, and only the operation of the rod 74 in the / direction is allowed. When the inserted electronic key 18 changes the piano wire 72, in conjunction with this, the mouth 74 moves in its fill // direction: ii without any rotational movement. As shown in FIG. 6, near the other end of the rod 74, a sleeve rest 78 supported by a stud 77 is provided. The sleeve 77 is fixed to the housing 46C of the mouth 46. As shown in FIG. 9, the sleeve rest 78 has a lead 78 A formed as a spiral groove. In this lead 78A, a pin 80 of the rod 74 is engaged (see FIG. 6 JD.) Such a movement. The linear movement of the rod 74 causes the linear movement of the sleeve rest 78 to rotate. It is changed to interlocking.

The sleeve rest 7 8 has the release arm 8 2 force '; screwed. ^ Rejection Room 8 2 The tip 82 A of the cam extends close to the cam 扳 58. By the child of the child key 18, the release arm 82 is in the state shown by the solid line in FIG. In this state, the distal end portion 8 2 A of the release arm 82 is separated from the cam plate 58, and does not interfere with the operation of the release arm 82 2 <the machine 48. Therefore, the above-described continuous operation by the rotary actuator 46 can be performed. When the electronic key 18 is pulled out from the hole 20, the piano wire 72 in the compressed state returns to its original shape, and the rod 74 moves back in conjunction with this. As a result, the sleeve rest 78 rotates clockwise one turn (see FIG. 6). As a result, the distal end portion 82 A of the removing arm 82 pushes the cam plate 58 in the clockwise direction to cause the roller 6 脱 to escape from the concave portion 58 A. As a result, the cam plate 58 is brought into the state shown by the solid line in FIG. In this case, the end 54 A of the connecting pin 54 is I :! 6A, the connection between the inner cylinder 14 of ^] and the second inner cylinder 16 is released. In the case of the above-mentioned latch elbow removal, no electrical action is required, and the key input operation and the key extraction operation are effective for releasing the latch. Icheon can. By the way, in order to prevent water droplets and) ^ from invading the inside of the mouth reactivator 46 from the li! J between the lock 1, 74 and the housing 46C, the liij gap is It is designed to be as small as possible without interlocking with Step 4. Grease is put in the gap, and L is formed.

On the other hand, since the rotary actuator 46 is closely attached to the inner peripheral surface of the inner cylinder 14 of [1], as shown in FIG. Water and dust power from the question of クチチ 4 6 6 連結連結連結連結連結連結連結連結. With the above configuration, even if water or dust is present from the keyhole 20, the jL and the like do not enter the mechanism 48 side. On the other hand, the above-mentioned dent 16 Λ is not a through-hole, so it is dust-proof and drip-proof.

It should be noted that the above-described components for dust-proofing and drip-proofing are only examples, and sealing materials such as rubber are used. May be used. The lock ffl cylinder 1 according to the present invention can reliably perform its original function over a long period of time, even in a poor Si environment. Next, the control circuit 84 will be described with reference to FIG.

The control circuit 84 includes a receiving coil RC, a power supply unit PS, an I'lj separate DC, and a drive unit OT. The power of the electronic key 18 is inserted into the keyhole 20 and the receiving coil RC is electromagnetically coupled with the transmitting coil TC of the electronic key 18 in the state shown in FIG. The power supply section PS obtains 11 DC power based on the output from the receiving coil RC, and ti power is supplied from the key side to the cylinder side. 1 Separate part DC is destroyed by the DC output from the fg source part PS, the code of the Gonko key input from the receiving coil RC; ', this!: Maekawa Cylinder The moving part 0 T is determined by the discriminating part DC by the discriminating part DC when the T child key force (if it is judged to be valid, is output by the class DC † In response to the signal DS, the current of 1 is supplied to the Ryukyu Reactuyue 46.

In this way, the control circuit 84 ijffl sends the transmission signal from the electronic key 18; the inserted key ^, the electronic key 8; the identification of the electronic key and the π- Complete the drive with 46 and a relatively short wand. This is because consumption of fE pond BT in Ding-key 18 can be as high as possible. Next, the entire movement of the lock lock cylinder 1 will be described.

When the lock key is not inserted into the lock cylinder, the latching state of the linkage 48 is reset by the release device 68. That is, the distal end portion 54 の of the connection pin 54 is protruded from the recessed portion 6A, and the inner cylinder 14 of the 内 and the second inner cylinder 16 are not connected. As a result, the inner cylinder 14 of 笫 1 can be freely rotated in the outer cylinder 1〇. Locking / unlocking mechanism of main body 100] It is not reached.

Due to the opening of the keyhole 42, the keyhole 20 of the inner cylinder 14 of the 笫 1 is? For V, for outside i 1 ϋ And the proper positional relationship is maintained. Therefore, the child key 18 can be securely inserted into the cylinder via the keyhole 42.

By such key insertion, the rod is advanced by 74 force, the arm 82 is set to the state shown by the solid line in FIG. 6, and the coupling mechanism 48 is made operable. In parallel with this, the control circuit receiving the transmission i from the electronic key 18 operates 84 circuits, and the control circuit 84 power << the electronic key 18 power; 'judge whether it is appropriate . Appropriate: On the stand that was judged to be a good one, the S-section driving current I was supplied to the rotary actuator 46, and the rotation of the rotary output 46D reduced the coupling machine by 48. You. This results in the latch state indicated by the two-dot chain line in FIG. By the way, by the above-mentioned key guide means, the inner [inn 4] is at an appropriate rotation angle to the outer [π], and the connecting pin 54 is always directed to the recess 16A. For this reason, it is not necessary to rotate the continuous spinning pin 54 so that the direction of the pin 54 is set to L'll 16 A. As a result, nif J that generates the drive current I from the control circuit 84 can be obtained in a very short time, and the consumption of the TB pool BT in the 15-child key 18 can be reduced.

If the position of the first [14] is indeterminate, depending on the situation, after inserting the fg child key 18, rotate the inner cylinder of [1] to search for an appropriate rotation. It must be, and during such an operation, it must supply fT power to the Ryukyu Reactuator 46 to govern it. According to the cylinder of the present embodiment, such a problem can be solved, the usability can be improved, and the frequency of replacing the battery 13 in the electronic key 18 can be reduced. As described above, the inner cylinder of 笫 1] and the second inner cylinder 16 and the force; by rotating the electronic key 18 in a state in which it can rotate as a whole with the The locking / unlocking machine 104 of the lock body 100 can be operated via the section 1 and the second inner cylinders 14 and 16. After locking or unlocking, when the electric key 18 is pulled out, this causes the rod 74 to retract; the unlocking arm 82 pushes down the cam temporary 58, causing it to tilt from the upright state to the inclined state. At this time, the distal end 54A of the cradle pin 54 escapes from the recess 16A, and the connection between the first inner cylinder 14 and the second inner cylinder 16 is released.

After that, even if the first inner cylinder 14 is rotated, this rotation is not transmitted to the solution mechanism 104 of the key rest. Therefore, unlike conventional cylinders, even if a screwdriver or the like is inserted into the keyhole 20 and turned, nothing is destroyed. It is absolutely impossible to operate. Therefore, the cylinder according to the present invention is extremely effective in crime prevention. Next, referring to FIG. 11, we will discuss other implementations of the means for latching. In the above-described embodiment, the latch means is drawn by means of a plate 66 and a force provisional 58 1111 part 58 A, etc., and the force ⁽ , in this embodiment, Magnet I is applied to Icheon. L, ru.

That is, when the protrusion 158 5 comes into contact with the permanent magnet 159, the protrusion 558A is attracted to the permanent magnet: I59 by the magnetic work ffl, and the cam temporary: Will be maintained. In this Η. 先端, the tip 54 の of the engaging bin 54 is recessed. Of course, the above magnetic Sakugawa needs to be larger and larger than the backwardly biased Sakugawa by the leaf spring 66. The advantage of this arrangement is compared with the growth shown in 1216, ^{communication:} machine ^ a lies in that can the small amount of rotation of the rotational output shaft 4 6 D of the rotary activator Yue Isseki 4 6 necessary for moving ΓΠ . That is, the amount of rotation of the 0-city output 粬 46 can be reduced by the amount of rotation necessary to make the roller 60 enter the recess 58 Λ. ; まままままま口を電子 g を f 電子電子電子電子電子電子電子電子電子電子電子電子 T

The pin 222 is provided with a thread 224, and the stud 224 has a hole 224 が into which an operation port 226 fixed to the rotation output 218 ロー of the low speed reactor 218 is inserted. I have. When sent from the electronic key 18 and received by the control circuit (not shown), the key is sent to the control key (not shown). You. As a result, the operation rod 226 is determined to have a force of <226: indicated by a solid line or a two-point line in FIG.

When the operating port 226 is in the state shown by the solid line, the connecting pin 222 is in front; Then, it proceeds to the position shown by the solid line, and the tip end 222 入り enters the recess 228 provided in the second inner cylinder 206. As a result, the first 2; 4 and the second 简 206 of the 笫 2 are connected to each other.

On the other hand, when the operation rod 226 is in the state indicated by the two-dot chain line, the connecting pin 222 retracts to return to the position indicated by the two-dot chain line. A escapes from the recess 228, and the connection between the first inner cylinder 204 and the second inner cylinder 206 is released.

The release of this connection state is performed by the release device ^ 216. Release machine 楛 2] 6 includes a leaf spring 2 32 and a release lever 23 36. The ϋ end of the leaf spring 232 is bolted to a partition 230 provided in 204 of 笫 1. The release lever 2 36 is guided by the partition wall 230 and the guide sleeve 234. As shown in Fig. 13, the release end of the release lever 23 is connected to one end of the release lever 23 and the movable end of the release lever is connected to the release lever 23 at the other end. A claw 2 3 6 され is formed, and this claw 2 3 (a pin extends to the working rod 2 2 6 and is pulled as shown in FIG. 13. See FIGS. 12 and 13). While explaining the operation of this release machine ^ 2 16 o
