Thereby, when the one end part of the inner wire 14B in the axial direction presses the wire receiving part 24C of the swinging member 24, the rotating shaft 24A rotates, and the claw part 24B swings toward the lock groove 40B. Accordingly, as shown in FIGS. 10 and 11, the claw portion 24B moves in the groove portion 26A of the lock pin 26, and the action of the push spring 28 causes the lock pin 26 to move toward the lock groove 40B (FIGS. 4 and Slide in the direction of arrow A in FIG. As a result, the distal end portion 26C of the lock pin 26 is fitted into one of the lock grooves 40B of the control tube 40, and the handle 12 connected to the control tube 40 is locked.

  On the other hand, in this bicycle interlocking lock 4, when unlocking the handle 12 and the rear wheel 6, the key 74 of the wheel locking device 8 is rotated in a predetermined direction (see FIG. 9). Thereby, the restraint of the yoke 62 is released, the return spring 64 contracts, the yoke 62 is pulled back into the apparatus main body 60, and the yoke 62 comes out from between the rear wheel 6 spokes, thereby unlocking the rear wheel 6. Is done.

  Simultaneously with the return of the yoke 62, the projection 66A of the operating lever 66 moves and the projection 66A moves away from the contact portion 68A of the wire fixing piece 68, so that the wire fixing piece 68 is shown in FIG. It moves in the direction opposite to the outer wire 14A. The inner wire 14B is pulled by the movement of the wire fixing piece 68 and moves in the direction opposite to the arrow C. Accordingly, the inner wire 14B that has pushed the wire receiving portion 24C in FIG. 4 upward is drawn into the outer wire 14A. At the same time, the rotating shaft 24A of the swinging member 24 is rotated by the action of the return spring 30, whereby the wire receiving portion 24C is rotated counterclockwise in FIG.

  As shown in FIGS. 5, 7, and 8, when the rotation shaft 24 </ b> A of the swing member 24 is rotated by the action of the return spring 30, the claw portion 24 </ b> B swings to the opposite side to the lock groove 40 </ b> B. The claw portion 24B presses the wall surface on the opposite side of the lock groove 40B in the groove portion 26A of the lock pin 26. As a result, the lock pin 26 slides in the unlocking direction (the direction opposite to the arrow A), and the distal end portion 26C of the lock pin 26 is disengaged from the lock groove 40B of the control tube 40. Thereby, the lock of the handle 12 connected to the control tube 40 is released.

  In the handle lock device 10, a restricting portion 32 is provided along the sliding direction of the lock pin 26 on the side of the claw portion 24B in the axial direction of the rotation shaft 24A. As shown in FIGS. 4, 7, and 8, the end portion 32 </ b> A (end portion on the substantially lower side in the vertical direction) of the restriction portion 32 protrudes from the claw portion 24 </ b> B along the axial direction of the head pipe 18. It is made into a shape. Thereby, when the lock pin 26 hits the side wall of the restriction portion 32, the lateral movement of the lock pin 26 is restricted. By this restricting portion 32, the state where the claw portion 24 </ b> B of the swing member 24 is inserted into the groove portion 26 </ b> A of the lock pin 26 is maintained, and the posture of the lock pin 26 is maintained. In this embodiment, the end portion 32A of the restricting portion 32 has a shape protruding from the claw portion 24B. However, the present invention is not limited to this, and the end portion 32A of the restricting portion 32 does not protrude from the claw portion 24B. Also good.

  In such a handle lock device 10, a load is applied to the handle lock device 10 (for example, when the handle 12 is forcibly rotated in a bicycle parking lot of the bicycle 2), and even if the main body case 20 is damaged, the lock pin When 26 hits the restricting portion 32, the lateral movement of the lock pin 26 is restricted. Thereby, the state where the claw portion 24B of the swinging member 24 is inserted into the groove portion 26A of the lock pin 26 is maintained. Therefore, in conjunction with the unlocking operation of the wheel lock device 8 (the operation of unlocking the handle lock device 10), the lock pin 26 of the handle lock device 10 can be slid in the unlocking direction. The lock can be released more reliably.

  Further, in the handle lock device 10 of the present embodiment, the restricting portion 32 is provided on the side of the claw portion 24B of the swing member 24, and the end portion 32A of the restricting portion 32 extends in the axial direction of the head pipe 18. It is set as the shape which protruded from the nail | claw part 24B along. Thereby, it is possible to prevent the groove 26 </ b> A of the lock pin 26 from coming off from the claw 24 </ b> B of the swing member 24 when the lock pin 26 hits the restricting portion 32, and the claw 24 </ b> B of the swing member 24 is The state inserted in 26A can be maintained more reliably.

  The restricting portion 32 is provided with a display portion 22 that displays the locked state and unlocked state of the handle 12, and the display portion 22 of the restricting portion 32 is moved by the swinging of the swinging member 24. The display unit 22 includes a red mark 22 </ b> A that displays a locked state and a blue mark 22 </ b> B that displays a unlocked state along the swinging direction of the restricting unit 32. 22 is identified. In such a handle lock device 10, the number of parts can be reduced by providing the display unit 22 in the restriction unit 32.

  FIG. 18 shows an internal configuration of the handle lock device 200 of the comparative example. As shown in FIG. 18, in the handle lock device 200, a swing member 202 is provided on the extending portion 20 </ b> B of the main body case 20. The swing member 202 includes a claw portion 202B protruding from the peripheral surface of the rotation shaft 202A, and the claw portion 202B is inserted into the groove portion 26A of the lock pin 26. A small-diameter portion 202C having an outer diameter smaller than the outer diameter of the rotating shaft 202A is provided on the distal end side (the side opposite to the return spring 30) of the rotating shaft 202A. The tip of the small diameter portion 202C is inserted into the concave portion of the plate-like piece 204 arranged in a direction intersecting the axial direction of the rotation shaft 202A, and the small diameter portion 202C is inserted into the concave portion of the plate-like piece 204 To rotate. The plate-like piece 204 is supported by being brought into contact with the inner wall of the extending portion 20 </ b> B of the main body case 20. A regulating portion is not provided on the rotation shaft 202 </ b> A of the swing member 202.

  The main body case 20 is provided with a guide groove 20D that guides the lock pin 26 along the sliding direction on the tip end portion 26C side of the lock pin 26. As shown in FIGS. 18 and 19A and 19B, the guide groove 20D includes a lateral surface portion 208A that surrounds the three surfaces of the lock pin 26, and longitudinal surface portions 208B and 208C on both sides of the lateral surface portion 208A. I have. On the back side of the guide groove 20D in the extension part 20B of the main body case 20 (on the side opposite to the cylindrical part 20A), a recessed part 20E that is recessed in a concave shape is provided, and the longitudinal direction of the guide groove 20D in the recessed part 20E A window portion 20C is provided at a position deviating from the extended lines of the surface portions 208B and 208C (see FIG. 19A). The main body case 20 is made of metal, and the periphery of the window portion 20C in the extending portion 20B is made of a thin plate material.

  In such a handle lock device 200, for example, if the handle is forcibly rotated in a bicycle parking lot or the like, the main body case 20 may be damaged by a load. Since the periphery of the window portion 20C of the recess portion 20E is formed of a thin plate material, the main body case 20 is formed of a thin plate material, and therefore the recess portion 20E along the boundary line between the vertical surface portion 208B and the lateral surface portion 208A on the window portion 20C side of the guide groove 20D. The crack 210 is likely to occur so as to divide the window portion 20C.

  Thus, when the crack 210 occurs in the main body case 20, the vicinity of the window portion 20 </ b> C of the hollow portion 20 </ b> E of the main body case 20 expands in the axial direction of the rotation shaft 202 </ b> A of the swing member 202. As a result, the lock pin 26 is displaced toward the window portion 20C (see FIG. 19A) of the hollow portion 20E of the main body case 20, and in some cases, the groove portion 26A of the lock pin 26 is disengaged from the claw portion 202B of the swing member 202. It may come off. In such a case, the lock pin 26 is pushed into a lock groove (not shown) by being pushed by a push spring (not shown), and the handle is locked. At that time, the groove 26A of the lock pin 26 is disengaged from the claw 202B of the swinging member 202 even if it is attempted to unlock the handle lock device 200 by the unlocking operation of the wheel lock device (see FIG. 9). There is a possibility that the lock pin 26 does not move and the handle is not unlocked.

  On the other hand, in the handle lock device 10 of the present embodiment, the restricting portion 32 is provided along the sliding direction of the lock pin 26 on the side of the claw portion 24B in the axial direction of the rotation shaft 24A of the swing member 24. It has been. For this reason, even if a crack occurs in the main body case 20 due to the load (see FIG. 19), the movement of the lock pin 26 to the side is restricted by the lock pin 26 hitting the side wall of the restriction portion 32, and the swing member The state in which the 24 claw portions 24B are inserted into the groove portions 26A of the lock pin 26 is maintained. For this reason, the handle 12 can be unlocked more reliably in conjunction with the operation of unlocking the handle lock device 10.

  In the handle lock device 10 of the present embodiment, the restricting portion 32 is disposed on the side of the main body case 20 where the window portion 20C is provided in the axial direction of the rotation shaft 24A. Thereby, even when the vicinity of the window portion 20 </ b> C of the main body case 20 is damaged, the restriction portion 32 prevents the lock pin 26 from shifting to the window portion 20 </ b> C side of the main body case 20. For this reason, the state where the claw portion 24B of the swinging member 24 is inserted into the groove portion 26A of the lock pin 26 can be more reliably maintained.
