[0022]
The operation in the above embodiment will be described below.
To attach the lock device 30 corresponding to the rear wheel 15, for example, as shown in FIGS. 2 to 4, the recessed surfaces of the connecting members 32 and 33 are brought into contact with the chain stay 9 from one side. After that, the connecting pad 34 facing the connecting member 32 is brought into contact with the chain stay 9 from the other side, and the connecting member 32 and the connecting pad 34 in a state where the chain stay 9 is sandwiched therebetween. And the case 31 is fixed to the frame 2 side.
[0023]
The lock device 30 is unlocked when the bicycle is used. That is, since the actuator 51 is inactive (described later), as shown by the solid line in FIG. 3, the operating body 53 is automatically retracted and the roller 54 is separated from the receiving plate portion 64a. In the toggle link mechanism 56, external force application is released. As a result, the locking metal members 37 and 38 are closed and swung around the support pins 41 and 42 by the elastic force of the winding springs 43 and 44, and as shown by the solid lines in FIG. 4 and FIG. All of them including 37a and 38a are stored in the case 31.
[0024]
In the link mechanism 56 with toggle at the time of such closed swing, both link bodies 63 and 64 are bent while rotating the rotating members 59 and 60, as shown by the solid line in FIG. Is performed in a direction approaching the actuator 51, and the receiving plate portion 64a is made to approach or abut against the roller 54 that has been moved in and out.
[0025]
When the lock device 30 is locked when the bicycle is not used, a lock radio wave is applied to the receiver 45 by operating the lock button 49 a of the transmitter 49. Then, an operation signal is given from the control unit 46 to the actuator 51, so that the operation body 53 projects and moves backward by the operation of the actuator 51. As a result, as indicated by an imaginary line in FIG. 3, the roller 54 comes into contact with the receiving plate portion 64a, and the receiving plate portion 64a is pushed and moved backward. That is, an external force is applied to the toggle link mechanism 56.
[0026]
As a result, in the link mechanism 56 with toggle, the link members 63 and 64 extend in a straight line while rotating the rotation members 59 and 60, and the rotation members 59 and 60 are moved away from each other by this extension. Thus, both the locking brackets 37 and 38 are opened and swung around the support pins 41 and 42 against the elastic force of the winding springs 43 and 44, so that the phantom lines in FIGS. As shown in FIG. 2 and FIG. 6, the claw portions 37a and 38a are projected from the inside of the case 31 through the penetrating portion 36 and are positioned between the spokes 15A. Thus, the lock apparatus 30 can be locked by positioning a pair of nail | claw part 37a, 38a between spoke 15A.
[0027]
In this locked state, for example, when trying to move the bicycle, the spoke 15A moved B by the rotation of the rear wheel 15 is brought into contact with the opposing surfaces of the locking fittings 37 and 38 as shown by the solid line in FIG. Further, the locking metal fittings 37 and 38 tend to be closed and swung by the moving force (locking force) of the spoke 15A.
[0028]
Then, by this closed swing, the spoke 15A that has moved B is locked to the V-shaped locking portions 37b and 38b as shown by the phantom line in FIG. 7, and at this time, the V of the locking portions 37b and 38b Due to the shape of the character, the moving force is distributed to the left and right, and the force for further swinging closed is smaller (small). The reduced closing swinging force is prevented by locking the toe portions 37c, 38c existing on the spoke 15A side with respect to the swinging locus A to the spoke 15A, and thus locked. Will be securely maintained.
[0029]
When unlocked for use in such a locked state, an unlocked radio wave is applied to the receiver 45 by operating the open button 49b of the transmitter 49. Then, the operation signal is cut from the control unit 46 to the actuator 51, so that the actuator 51 is deactivated, and as described above, the operating body 53 is automatically retracted and moved to the receiving plate portion 64a. On the other hand, the roller 54 is separated.
[0030]
Thus, since both the locking metal fittings 37 and 38 move back and forth with respect to the case 31 by swinging, the thickness in the vehicle width direction can be reduced and the size can be reduced.
When the unlocking operation by the transmitter 49 or the locking operation by the transmitter 49 described above is performed and the receiver 45 receives and unlocks or locks, the alarm 47 sounds and the LED The lamp 48 is turned on, so that the completion of the operation can be notified.
[0031]
As described above, unlocking and locking of the lock device 30 can be performed by giving the receiver 45 an unlocking radio wave and a locking radio wave by operating the button of the transmitter 49. That is, the unlocking operation and the locking operation are remotely controlled. Therefore, the operation can be performed easily and lightly in an easy posture even in a narrow place or a dark place, and can be reliably performed from a slightly separated position.
(Embodiment 2)
As shown by the phantom line in FIG. 1, the case 31 is fixed to the front fork 12, and the lock device 30 is attached corresponding to the front wheel 13. In this case, both the locking fittings 37 and 38 act on the spoke 15A of the front wheel 13.
[0032]
In both the above-described embodiments, the electric actuator 50 is operated without contact by the button operation of the transmitter 49, but this is a touch operation (such as a memorization number) on the contact operation unit provided on the case 31 side. By doing so, the structure which operates the electric actuator 50 may be sufficient.
[0033]
In both of the above-described embodiments, the electric actuator 50 is operated in a contactless manner by operating the dedicated transmitter 49, but this is a locking operation and an unlocking operation using radio waves such as a mobile phone and a PHS. It may be in a form that performs.
[0034]
【The invention's effect】
According to claim 1 of the present invention described above, by adopting the electric actuator, locking and unlocking can be performed by button operation or touch operation, even if the operation is in a narrow place or dark place, It can be easily and lightly and reliably performed in an easy posture, and both locking brackets move back and forth with respect to the case by swinging, so the thickness in the vehicle width direction can be reduced and the size can be reduced.
