A spring receiving groove 860 in which a spring 850 for elastically supporting the movable locking piece 810 may be formed in the fixing frame.

As shown in FIG. 3, the spring receiving groove 860 is formed in the case 100, but FIGS. 8 and 9 are shown to be formed in a separate housing for convenience in order to facilitate understanding.

Of course, it is also possible to form a spring receiving groove 860 by providing a separate housing.

Accordingly, when the rotor part 300 rotates counterclockwise to the "initialization" position, the driving plate 830 rotates together, and the stepped section 831 of the driving plate 830 becomes the moving locking piece ( When 810 is pushed toward the spring receiving groove 860, the movable locking piece 810 is elastically supported by the spring 850 and is always restored in a direction toward the outside of the spring receiving groove 860. It is configured to have.

Will come true.

As shown, the inclined guide part 811 preferably has an isosceles inclined surface symmetrical with respect to the center in the width direction of the moving locking piece 810, but may be configured as a convex curved surface having the center as a vertex. It may be composed of a plurality of convex squares.

As shown in Fig. 8(c), when the guide protrusion 460 is subsequently caught in the guide hole 832 and transmits a rotational force to the mode selection rotating body 400, the blocking protrusion 450 is The "initialization" mode is completed by pressing the inclined surface of the inclined guide part 811 so that the moving locking piece 810 additionally moves within the spring receiving groove 860.

When the driving plate 830 rotates, when the opposite end of the guide hole 832 contacts the guide protrusion 460, the blocking protrusion 450 is already in contact with the inclined guide part 811 so that the blocking protrusion During rotation of 450, it is necessary to push the inclined guide part 811 without being caught by the movable locking piece 810 so that the movable locking piece 810 moves into the spring receiving groove 860.

When the "initialization" mode is completed, the dial 700 is rotated to initialize the password set at the time of manufacture.

As shown in Fig. 8(d), when the handle 200 is rotated clockwise when the "initialization" of the password is completed, the guide hole 832 and guide when the driving plate 830 rotates clockwise. Since the protrusions 460 do not interlock, relative movement is made until the guide protrusion 460 reaches one end of the guide hole 832.

By pressing the inclined surface of 811 so that the movable locking piece 810 additionally moves within the spring receiving groove 860, the return to the "locked" mode is completed.

On the other hand, as shown in Figure 8 (c), by inserting the master key into the key insertion hole 210 of the handle 200 to release the coupling between the rotor unit 300 and the mode selection rotating body 400 In the state, when the handle 200 is turned to the "initialization" mode, the mode selection rotating body 400 is rotatable with a time difference from the start time of rotation of the rotor unit 300, and the initialization groove 440 becomes the shaft 500 Will face the top of.

The support body 680 is a support plate 682 disposed on the uppermost dial 700, and a rotor part 682 extending from the support plate 682 along the longitudinal direction of the shaft 500 and around the shaft 500 It includes fitting pieces 681 separated on both sides along the axial direction of 300, and the initializing groove 440 of the mode selection rotating body 400 is a first insertion groove supporting the upper end of the shaft 500 ( 441 and a second insertion groove 442 disposed adjacent to the first insertion groove 441 along the axial direction of the rotor part 300 and supporting the fitting piece 681, 1 The insertion groove 441 communicates with the locking groove 410 supported by the shaft 500 when locked, and is formed deeper than the depth of the locking groove 410 with respect to the outer circumferential surface of the mode selection rotating body 400. .

The depth between the locking groove 410 and the outer circumferential surface of the mode selection rotating body 400 is maintained substantially the same as the depth between the bottom of the first insertion groove 441 and the bottom of the second insertion groove 442 Preferably, in the "locked" mode and the "initialized" mode, it is preferable to keep the relative heights of the shaft 500 and the rotary transmission tube 600 constant, respectively.

Accordingly, when the handle 200 is rotated to the initial position, the fitting piece 681 enters the second insertion groove 442 and is supported on the bottom surface, and the upper end of the shaft 500 The first adjustment protrusion 730 is separated from the dial 700 by being supported on the bottom of the first insertion groove 441 and raising the rotation transmission tube 600, and formed in the coupling hole 710 of the dial 700. ) And the second adjustment protrusion 630 formed on the outer circumferential surface of the rotation transmission tube 600 reach a position in which side contact is possible.

On the other hand, on the outer circumferential surface of the mode selection rotating body 400, the fitting piece 681 and the shaft 500 are inserted to form a non-number changing groove 430 for performing a non-number changing function, and the non-number changing groove 430 ) Is formed to be shallower than the depth of the second insertion groove 442, and the first adjustment protrusion 730 and the first adjustment protrusion 730 and the first adjustment protrusion 730 and the first adjustment protrusion 730 and the first adjustment protrusion 730 and the first adjustment protrusion 730 and the first adjustment protrusion 730 and the second 2 Side contact of the adjustment protrusion 630 does not occur, and the password can be easily changed by rotating the dial 700.

A support spring 690 is interposed between the shaft 500 and the lower portion of the rotation transmission tube 600 and the bottom of the case 100 so that the shaft 500 and the rotation transmission tube 600 are mode-selective rotation bodies. It is configured to receive a force that is always restored upward toward the outer circumferential surface of (400).

As shown, the support spring 690 may be installed in the case 100 indirectly through the floor support sheet 900.

Hereinafter, the operation of the dial-type lock according to the present invention will be described with reference to FIGS. 9A to 9E.

The following description reveals that not only password initialization, which is the main feature of the present invention, but also functions related to locking, opening, and password change, and other suitable known configurations may be adopted for locking, opening, and password change except for password initialization. Put it.

First, in Fig. 9a, the handle 200 is in the "locked" position, but the password of the dial 700 is matched, and the locking protrusion 510 of the shaft 500 in the circumferential direction is caught in the rotation transmission box 600 It shows a configuration that matches the groove 610.

In this state, the handle 200 can move to the "open" position or freely move back to the "lock" position, which means that the locking protrusion 510 of the shaft 500 is the locking groove 610 of the rotating transmission box 600 This is because the bottom surface of the locking groove 410 of the mode selection rotating body 400 can be lowered by pushing the upper end of the shaft 500 according to the rotation of the handle 200.

In this case, the upper end of the shaft 500 supports the bottom of the locking groove 410, while the fitting piece 681 of the support body 680 installed around the shaft 500 is the locking groove 410 Since it is not inserted into the mode selection rotator 400 and comes into contact with the outer circumferential surface, the engaging protrusion 620 of the rotating transmission tube 600 is coupled to the engaging engaging groove 720 of the dial 700. Keep.

In addition, the locking protrusion 510 of the shaft 500 is disposed above the rotation transmission tube 600 so that the rotation transmission tube 600 can be freely rotated.

Of course, in this case, the lower end of the shaft 500 and the lower end of the rotation transmission tube 600 are elastically supported by a support spring 690, so that the shaft 500 and the rotation transmission tube 600 are mode-selective rotating bodies. It is configured to receive a force restored upward toward the locking groove 410 of (400).

Next, as shown in FIG. 9B, if the plurality of dials 700 are rotated arbitrarily to disperse the password, a plurality of rotations by the engaging projections 620 engaged with the engaging groove 720 of the dial 700 The delivery tube 600 rotates together.

As each of the rotation transmission cylinders 600 rotates, the locking protrusion 510 of the shaft 500 in the circumferential direction does not coincide with at least one locking groove 610 of the plurality of rotation transmission cylinders 600.

Accordingly, since the locking protrusion 510 of the shaft 500 is caught on the upper end of the rotation transmission box 600 and cannot descend, the mode selection rotating body 400 is Since the shaft 500 cannot be lowered, it is possible to maintain the locked state as it is.

Figure 9c shows a state in which the handle has moved to the "open" position, and for this purpose, the locking protrusion 510 of the shaft 500 in the circumferential direction by first rotating the dial 700 to match the password After making it coincide with the locking groove 610 of the 600), when the handle 200 is turned from the "locked" position to the "open" position, the latch L connected to the rotor unit 300 is opened.

In this case, the upper end of the shaft 500 supports the bottom of the opening groove 420, while the fitting piece 681 of the support body 680 installed around the shaft 500 is in the opening groove 420 Since it is not inserted and comes into contact with the outer circumferential surface of the mode selection rotating body 400, the engaging protrusion 620 of the rotating transmission container 600 remains engaged with the engaging engaging groove 720 of the dial 700. do.

Figure 9d shows a state in which the handle has moved to the "password change" mode, and for this purpose, the locking protrusion 510 of the shaft 500 in the circumferential direction by first rotating the dial 700 to match the password After making it coincide with the locking groove 610 of 600, by turning the handle 200 from the "open" position to the "password change" position, the password can be changed.

In this case, the upper end of the shaft 500 and the rotation transmission tube 600 are both in contact with and support the bottom of the non-turn changing groove 430, so that the rotation transmission tube 600 rises with respect to the dial 700 by that amount. Thus, the engaging projection 620 of the rotation transmission cylinder 600 is released from the state in which the engaging projection 620 of the dial 700 is engaged with the engaging groove 720.

Accordingly, the dial 700 is separated from the rotation transmission box 600 and rotates freely, so that the desired password can be changed.

Once the password is changed, the handle 200 is rotated counterclockwise again to move to the "open" mode or the "lock" mode, and the dial 700 can be rotated to scatter the password.

Finally, as shown in Fig. 9e, in the case of initializing the password, when the handle 200 is turned to the initial position while the master key is inserted into the key insertion hole 210 of the handle 200, the The rotor unit 300 separated from the mode selection rotating body 400 rotates in a counterclockwise direction, and at the same time, the driving plate 830 fixed to the rotor unit 300 rotates.

At this time, the stepped section portion 831 presses the inclined guide portion 811 so that the movable locking piece 810 moves elastically in the spring receiving groove 860 first, and subsequently the guide protrusion ( When 460 is caught in the guide hole 832 and transmits a rotational force to the mode selection rotating body 400, the blocking protrusion 450 presses the inclined guide part 811 so that the movable locking piece 810 accommodates the spring. It is configured to move further within the groove 860.

When the driving plate 830 rotates, when the opposite end of the guide hole 832 contacts the guide protrusion 460, the blocking protrusion 450 is already in contact with the inclined guide part 811 so that the blocking protrusion When the movable locking piece 810 is rotated, the movable locking piece 810 is further moved into the spring receiving groove 860 by pushing the inclined guide part 811 without being caught in the movable locking piece 810.

In this way, the handle 200 is initialized in a state in which the coupling between the rotor part 300 and the mode selection rotating body 400 is released by inserting the master key into the key insertion hole 210 of the handle 200. When turned to, the mode selection rotor 400 is rotatable with a parallax from the start point of rotation of the rotor unit 300, and the initialization groove 440 faces the upper end of the shaft 500.

That is, while the fitting piece 681 surrounding the shaft 500 enters the second insertion groove 442 of the initialization groove 440 and is supported on the bottom surface, the upper end of the shaft 500 By being supported on the bottom of the first insertion groove 442, the rotation transmission tube 600 is raised and separated from the dial 700, and the shaft 500 is the highest to the bottom of the first insertion groove 442. Ascending, the first adjustment protrusion 730 formed in the coupling hole 710 of the dial 700 and the second adjustment protrusion 630 formed on the outer circumferential surface of the rotary transmission tube 600 reach a position where side contact is possible. do.

In this way, when the first adjustment protrusion 730 and the second adjustment protrusion 630 are maintained in height so that the side surfaces of the second adjustment protrusion 630 contact each other, the first adjustment protrusion 730 is rotated when the dial 700 is rotated. 2 The adjustment protrusion 630 can be rotated, and the password is initialized to the initially set password.

That is, when the dial 700 is rotated by more than 360 degrees so that the password (0, 0, 0, 0) at the time of manufacture is visible, the side surfaces of the first adjustment protrusion 730 and the second adjustment protrusion 630 are in contact. In one state, the password is initialized, and in this state, when the handle 200 is rotated counterclockwise, it returns to the "locked" position.

In this state, the password at the time of manufacture is known, so you can freely reset the password by moving the handle to the "password change" mode.

Even during reverse rotation, when the guide protrusion 460 is caught in the guide hole 832 and transmits a rotational force to the mode selection rotating body 400, the blocking protrusion 450 moves by pressing the inclined guide part 811 The locking piece 810 is configured to additionally move into the interior of the spring receiving groove 860.

In the above-described embodiment, the off-number change function is also basically described, but the off-time change function is optional, and the off-time change groove 430 and the "password change" mode may be omitted.

The non-described constituent symbol "S" is a dial support for supporting the dial 700 to the case 100 and serves to elastically support the dial 700 so that it feels like one number is caught when rotating the dial 700, 670 is a support piece that simultaneously supports the shaft 500 and the rotation transmission tube 600 and is supported by the support spring 690.

In addition, the component "M" is a component that connects the rotor unit 300 and the latch L.
