Description

Free wheeling type locking apparatus

The present invention relates to a locking device provided in a door of an automobile, and the like, in particular, when a key is opened to insert a heterogeneous key other than a normal key, the key is freely rotated but the lock is not released so that the locking device is forced. A free wheeled locking device is provided to prevent release or breakage.

Typically, a vehicle is provided with a locking device for a door, a trunk, a starting device, and the like.

A general locking device is provided with a rotor in a case and is configured to be locked or unlocked by inserting and rotating a key in the rotor.

However, the general locking device is configured to lock and unlock the key only when the rotor is inserted by inserting a key. Therefore, when the rotor is forcibly rotated by a tool or a dissimilar key shaped like a normal key, the lock is released. There was a disadvantage that the locking device could be broken.

Therefore, recently, a freewheeling locking device has been developed in which the rotor rotates freely but the lock is not released when a tool such as a driver or a heterogeneous key is inserted to release the lock.

1 to 5 are diagrams showing a freewheeling locking device of the prior art, which are reference drawings of a 'cylinder lock specifically designed for a vehicle' disclosed in 'Patent Application Publication No. 97-702416'.

1 is a longitudinal sectional view showing an operating state of the locking device when the normal key is inserted, Figure 2 is a longitudinal sectional view showing an operating state of the locking device when the heterogeneous key is inserted.

In the locking device of the present invention as shown in the drawings, a plurality of lock plates 4 are arranged in the rotor case 1 so that a rotor 2 which is rotated at the same time as the key is rotated is installed. In the circumference of the rotor case 1, a holder 5 is installed.

The rotor (2) has a long shaft portion (3) is extended to the rear of the rotor case (1), the actuating lever (6) is mounted to the shaft portion (3) of the rotor (2) through a snap ring (7) The operating force at the time of locking or releasing the lock is transmitted to the locking device (not shown).

A clutch member 9 is provided between the actuating lever 6 and the holder 5 to be in close contact with the rotor 2 and the holder 5 by a return spring 8. The rotational force of the rotor 2 is transmitted to the operating lever 6 side only when combined with the operating lever 6 to operate with the normal key T.

Here, the coupling means 10 consisting of a protrusion and a groove is provided between the rotor 2 and the clutch member 9, so that when the rotor 2 is rotated by inserting the normal key T as shown in FIG. The member 9 is also rotated at the same time so that the operation lever 6 can be moved.

Meanwhile, as shown in FIG. 2, the holder 5 is rotated together with the rotor 2 while being caught by an exposed portion of the lock plate 4 when forcibly rotating the rotor 2 with a heterogeneous key F or the like. consist of.

Of course, when the normal key (T) is inserted into the rotor 2 as shown in Figure 1, since the lock plate 4 is aligned with the inside of the rotor 2, the rotation of the holder 3 is not made.

When the clutch ball 15 is provided between the holder 5 and the clutch member 9 such that the holder 5 is rotated by the heterogeneous key F or the like, the clutch ball 15 as shown in FIG. 2. ) Moves the clutch member 9 in the direction of the operating lever 6.

Therefore, as the coupling means 10 between the rotor 2 and the clutch member 9 is separated, when the rotor 2 is rotated using the heterogeneous key F, only the rotor 2 and the holder 5 continue. The clutch member 9 and the operation lever 6 are fixed without rotation, making it impossible to perform the locking operation or to release the lock.

3 and 4 are diagrams representing the state when trying to release the lock by inserting the heterogeneous key (F) as described above, the holder 5, the groove portion 5a on which the clutch ball 15 can be seated Is formed, and the clutch member 9 is provided with a ball action portion 9a protruding in the circumferential direction so as to cope with when the ball 15 is moved in the axial direction.

Therefore, when the rotor 2 is not rotated or the rotor 2 is rotated by inserting the normal key T, the clutch ball 15 enters the groove 5a of the holder 5 as shown in FIG. However, when the holder 5 is rotated with the hetero key F or the like, the clutch ball 15, which is fixed in the rotational direction, moves along the guide groove 1a as shown in FIGS. 9) is pushed, and the coupling means 10 between the rotor 2 and the clutch member 9 is separated as shown in FIG. 2, thereby preventing normal operation.

However, the clutch ball 15 is separated from the groove portion 5a of the holder 5 by the hetero key, etc., as shown in FIG. 4 in the above-described prior invention as described above, so that the holder 5 and the clutch member 9 are separated. If the lock key is inserted in the state in between to perform lock and release operation later, only the rotor 2 is idle by the normal key, so that the operating force of the key is not immediately transmitted to the operating lever 6 side. There is this.

That is, as shown in FIG. 4, when the clutch ball 15 is separated from the groove portion 5a and positioned between the holder 5 and the clutch member 9, the coupling means between the rotor 2 and the clutch member 9 ( 10) is in a separated state, and when the normal key is inserted, the lock plate 4 is aligned with the inside of the rotor 2, so only the rotor 2 rotates according to the rotation of the normal key, and the holder 5 and the clutch member are rotated. (9) has a problem that the normal operation is difficult because the operating force of the normal key is not transmitted to the operating lever 6 and the locking device side by not rotating.

On the other hand, Figure 5 is a view of another embodiment of the invention described above, as described above, without using the clutch ball, the projection (9a ') is integrally formed on the clutch member (9') of the holder 5 ' Since the holder 5 'is rotated by being fitted in the groove 5a', the clutch member moves in the axial direction.

However, when the rotor 2 'is rotated by inserting the normal key in the state where the groove 5a' and the protrusion 9a 'are separated according to the operation of the heterogeneous key or the like according to another embodiment of the above-described prior application, Since only the rotor 2 'is rotated, a problem arises in that the normal operation of the locking device is not easily performed.

The present invention has been made to solve the above problems, the rotation of the rotor with a heterogeneous key by the clutch member is configured to be quickly coupled to the rotor when operating the normal key again in the state that the clutch member is separated by the quickness of the normal key operation It is to provide a free wheeling locking device to improve the and reliability.

Free wheeling locking device of the present invention for realizing the above object, the rotor case; A rotor installed in the rotor case and provided with a plurality of lock plates arranged inwardly when a normal key is inserted, the rotor having a driving plate protruding at an end thereof; A clutch member coupled to the drive plate of the rotor and rotated; An actuating lever coupled to the clutch member at the end of the rotor case to transmit an actuation force of a normal key to the locking device; An elastic member supported by the operation lever to provide an elastic force to the clutch member; A holder rotatably installed between the rotor and the rotor case and simultaneously rotated by the lock plate when the rotor is rotated by a heterogeneous key; It is possible to be provided between the holder and the clutch member, characterized in that consisting of a slider that is coupled to the drive plate while separating the clutch member from the drive plate of the rotor when the holder is rotated.

The free wheeling locking device of the present invention includes a rotor 60 in which a key is inserted into the rotor case 51, a holder 70 rotated when a heterogeneous key is inserted, a slider 75 in close contact with the holder, and a normal key inserted therein. When the clutch member 80 and the operating lever 90 and the like rotated along the rotor 60 is assembled.

The rotor case 51 is formed in a cylindrical shape, the case cover 55 is coupled to the front portion, and the rear portion is formed to be open to engage the operation lever 90. In addition, the inner surface of the rotor case 51 has a groove portion 52 for limiting rotation of the slider 75 and a stopper 53 for limiting the axial movement and rotation range of the clutch member 80 in FIG. 7. The protrusion 54 is formed.

The rotor 60 is formed with a key groove 61 is inserted into the key so that the locking operation and the release operation in the front portion, a plurality of lock plates protruding out by the elastic member 66 in the radial direction around both sides 65 is installed.

In this case, the lock plate 65 overcomes the elastic force of the elastic member 66 when the normal key is inserted into the key groove 61 of the rotor 60 and is aligned with the inside of the rotor 60 to rotate the rotor 60. Free

A shaft portion 62 extends at an end of the rotor 60, and a drive plate 63 coupled to the slider 75 and the clutch member 80 protrudes on both sides of the shaft portion 62.

The holder 70 is formed in a cylindrical shape so as to be rotatably mounted between the rotor 60 and the rotor case 51, and a groove 71 is formed on an inner circumferential surface of the holder 70 to catch the lock plate 65. Two grooves 72 are formed on both sides of the holder 70 so as to be coupled to the slider 75.

The holder 72 does not rotate when the normal key is inserted into the key groove 61 so that the lock plate 65 is not caught. However, when the heterogeneous key is inserted, the lock plate 65 protrudes out of the rotor 60. It is configured to rotate at the same time.

The clutch member 80 has a coupling hole 81 through which the axial part 62 of the rotor penetrates and the drive plate 63 is inserted so that the rotor 60 rotates at the same time as the rotor 60 is rotated. In the groove portion 82 is formed so that the rotation range is determined for the protrusion 54 of the rotor case 51.

Here, the coupling hole 81 is formed to protrude in the rear direction to receive a rotational force within a predetermined range of the axial direction from the drive plate 63.

In addition, a coupling protrusion 83 is formed on the rear surface of the clutch member 80 so as to be coupled to the operation lever 90 to transmit an operation force.

The clutch member 80 is provided with an elastic force to be in close contact with the stopper 53 of the rotor case 51 by the elastic force of the return spring 85 supported by the operation lever 90.

The operation lever 90 is mounted to the end of the shaft portion 62 of the rotor 60 to allow relative rotation, and is supported so as not to be separated through the snap ring 95.

The operation lever 90 is connected to the end portion 91 is connected to the locking device (not shown) side to transmit the operating force while rotating a certain time when locking or releasing the normal key.

The slider 75 is formed in the shape of a disc ring of a predetermined thickness, positioned between the holder 70 and the clutch member 80, and a cam portion 76 protruding corresponding to the groove portion 72 of the holder 70. Is formed, and the driving plate 63 of the rotor is coupled and rotated while the cam portion 76 is separated from the groove portion 72 of the holder while the shaft portion 62 of the rotor 60 penetrates at the center portion thereof. Coupling hole 77 is formed.

In addition, the slider 75 is formed with two protrusions 78 which are seated in the groove 52 of the rotor case so that the rotational movement is limited when the heterogeneous key is initially inserted and rotated.

The slider 75 pushes the clutch member 80 while the cam part 76 is separated from the groove part 72 of the holder 70 when the holder 70 is rotated by a hetero key. It serves to depart from the drive plate (63) of. In addition, the slider 75 pushes the clutch member 80 and is coupled to the driving plate 63 of the rotor 60 to rotate together with the rotor 60 and the holder 70.

On the other hand, the above-mentioned groove portion 71 of the lock plate 65 and the holder 70 to which the lock plate is coupled, the drive plate 63 of the rotor 60 and the slider 75 and the clutch member to which the drive plate is coupled. The coupling holes 77 and 81 of the 80, the protrusions 78 of the slider 77, the grooves 52 of the rotor case 51, and the like are formed on the upper and lower sides in the vertical direction like the key grooves 61, respectively. In the horizontal direction orthogonal thereto, the groove portion 72 of the holder 70 and the cam portion 76 of the slider 75 are formed on both sides.

Referring to the operation of the free wheeling locking device according to the present invention configured as described above are as follows.

In the state in which no key is inserted, as shown in FIG. 8, the lock plate 65 protrudes out of the rotor 60, and the driving plate 63 of the rotor 60 is engaged with the coupling member 81 of the clutch member 80. ) Will be inserted into.

When the normal key is inserted into the key groove 61 of the rotor 60 in such a state, the lock plate 65 is aligned with the inside of the rotor 60 by the key string so as not to restrain the holder 70.

Then, as shown in FIGS. 6 and 7, when the normal key is rotated, the rotor 60 is rotated in the 'A' direction, and the driving plate 63 is also rotated at the same time. At this time, the clutch member 80 coupled to the driving plate 63 is rotated. ) Is also rotated in the 'B' direction to rotate the operation lever 90 in the 'C' direction to operate the locking device.

Unlike the above, when a driver or a heterogeneous key is inserted into the key groove 61, the lock plate 65 is in a state of protruding to the outside of the rotor 60 as it is. At this time, the rotor ( Forcibly rotating the 60 in the 'A' direction causes the holder 70 to also rotate in the 'D' direction by the lock plate 65.

At the same time, the slider 75 seated in the groove 52 of the rotor case 51 and the rotational movement of which is limited in the 'E' direction, while the cam portion 76 is separated from the groove 72 as the holder 70 rotates. An axial movement is made, and the clutch member 80 is pushed in the 'F' direction.

At this time, the clutch member 80 is separated from the drive plate 63 of the rotor 60, and the slider 75 is coupled to the drive plate 63 to rotate together.

Therefore, as the clutch member 80 is completely separated from the rotor 60, even when the rotor 60 is rotated by a hetero key or the like, only the rotor 60, the holder 70, and the slider 75 rotate, and the clutch member is rotated. The operating force of the key is not transmitted to the 80 and the operating lever 90 side.

After removing the heterogeneous key in such a state, when the normal key is inserted later, the lock plate 65 is aligned with the inside of the rotor 60, and when the key is rotated, the rotor 60 and the slider 75 are At the same time, the holder 70 does not rotate.

When the rotor 60 and the slider 75 are rotated to some extent, the slider 75 is engaged with the groove portion 72 of the holder 70 while the protrusion 78 of the slider 75 is the groove portion of the rotor case 51. While being inserted into 52, it moves in the opposite direction of 'E', and at the same time, the clutch member 80, which has compressed the return spring 85, also moves in the opposite direction of 'F'.

As a result, the clutch member 80 is coupled to the drive plate 63 of the rotor 60 again, and the operating force of the normal key is transmitted to the operation lever 90 to perform the locking operation and the release operation of the locking device. do.

Therefore, the freewheeling locking device of the present invention constructed and operated as described above allows the lock operation and release operation to be performed in a short time when the normal key is reinserted even when the rotor and the clutch are separated by a hetero key. Since the rotor and the clutch are configured to be coupled, there is an advantage of preventing the risk of the locking device being broken by a dissimilar key or the like and realizing a quick normal operation function.
