DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a lock A is a conventionally known bicycle
The lock A has a similar structure to that of the locking lock.
Power switch B and external device via lead c
Switch C connected to the power switch B from the
The battery is installed in the upper part of the front A as described later.
Lock lever 14 for locking the lock lever for attaching and detaching the
ing.

The lock A has an arc-shaped lock rod 2 slidable in a lock body 1 which is formed in a circular arc shape by a base a and a case b which are formed in a horseshoe shape and are fitted to each other at the periphery. A lock mechanism 4 for holding the lock rod 2 at the lock position or releasing the lock rod 2 from the lock position is provided on the upper right hand side of FIG. 1 together with the coil-shaped restoring spring 3 pulled from the rear end.

The lock mechanism 4 mainly uses a conventionally known cylinder lock mechanism, and projects into the lock body 1 and rotates with the rotation of the key 12. The square shaft 5 rotates integrally with the square shaft 5. The lever 6, the click spring 7 for holding the locking lever 6 in the rotating position, and the square shaft 5 are fitted to the rear end of the U-shape, and the front end is advanced and retracted toward the side surface of the arc-shaped locking rod 2. And a stopper 8 for preventing the locking rod 2 from retreating in the locking position shown in FIGS.

A stopper 8 engages a projection 8 'with a notch 6' provided on one side of the locking lever 6, while a small coil having a projecting shape is provided between a spring receiver 8 "provided on the back side of the drawing and the body. A spring 9 is provided.

As described above, the power switch B connected to the hand switch C via the lead wire c is shown in FIGS.
As shown in FIG. 4, the swingable operating contact piece 10 is installed in the lock main body 1 so as to approach one side of the locking lever 6. In the unlocked state of the lock rod 2 shown in FIG. 1, the operating contact piece 10 is pressed against the side surface of the locking lever 6 at the unlocked position to keep the power supply circuit ON.

First, the locking operation of the lock A and its operation will be described. In the unlocked state shown in FIG. 1, the handle 11 provided on the outer side of the lock main body 1 is rotated, and the arc-shaped lock rod 2 is shown. After being advanced to the position shown in FIG. 3, the key 1 shown in FIG.
When the lock lever 2 is rotated in the locking direction on the right side in the figure, the locking lever 6 rotates counterclockwise from the position shown in FIG. 1 through the square shaft 5 as shown in FIG.

When the locking lever 6 is displaced to the locking position, the stopper 8 urged by the coil spring 9 moves forward and fits into the locking portion 13 provided at the rear of the arc-shaped locking rod 2 to lock the lock. Hold the rod 2 in the locked position. On the other hand, the power switch B, which has maintained the power circuit ON, opens the operating contact 10 as shown in FIG. 3 by the displacement of the locking lever 6 to the locking position, and switches the power circuit OFF.

Next, the unlocking operation and its operation will be described. When the key 12 is rotated in the opposite direction to the locking operation, the stopper 8 connects the projection 8 'and the notch 6' of the locking lever 6 which rotates in the reverse direction. Engaged and retracted to the unlocked position shown in FIG.
When the front end of the lock rod 2 is released from the hook 13,
Is urged by the restoring spring 3 to return to the unlocked position. Also,
At the same time, when the locking lever 6 is displaced to the unlocked position, the operating contact piece 10 is pressed and the power switch B returns to ON.

[0018] The padlock A hand, apart from the Jo杆2 governed by the lock mechanism 4 as described above, set at the top, as described above
A lock lever 2 for attaching and detaching the battery in the recess 15
3 is provided with a locking rod 14 for hooking and releasing.

This other locking rod 14 is shown in FIG.
As described above, the lock lever 6 is provided so as to penetrate through the through-holes 17 on both inner side walls of the concave portion 15 and is connected to the locking lever 6 via an L-shaped link 19 having an elongated hole 18. .

The elongated hole 18 includes an arc portion 20 having the square axis 5 as the center of gravity and a straight portion 21 continuing from the end of the arc portion 20 in a direction away from the center of the circle, and a pin 22 provided on the locking lever 6. Are fitted into the same long holes 18 to slide the L-shaped link 19 following the rotation of the locking lever 6 to move the locking rod 14 forward and backward.

That is, when the pin 22 is fitted in the arc portion 20 of the elongated hole 18, the displacement of the locking lever 6 from the unlocked position to the locked position requires the L-shaped link 19 to be displaced. because it does not cause the swing, locking rod 14, as shown in FIGS. 1 and 2, the upper portion of the recessed portion 15 of the lock body 1
It penetrates the inside horizontally and keeps the locked state of closing the opening of the concave portion 15 .

The locking lever 6 has a rotation allowance that can be further rotated in the locking rotation direction without changing the locking state in which the stopper 8 is advanced to fit into the locking portion 13 of the arc-shaped locking rod 2. During rotation from the locking position to the second locking position, the fitting position of the long hole 18 and the pin 22 is moved from the end of the arc portion 20 to the linear portion 21 so that the L-shaped link 19 is formed. Causes sliding.

The locking lever 6 is displaced to the second locking position,
By locking rod 14 link 19 is slid is drawn into the inner wall 16, the lock lever 23 for the battery detachable being locked in該施Jo杆14 as shown in FIG. 6 <br/> swing Opened as possible.

As shown in FIG.
The rear hawk 24 of the bicycle above the lock A mounting position
A notch 27 is provided so as to be swingable about a support shaft 25 suspended between the two ends, and has a horizontal hole 26 at one end through which the locking rod 14 penetrates and is locked, and a projection at the back surface at the other end.
Can be pulled out by pushing the front end of the lock lever 23, which is released from the locking rod 14, into the concave portion 30 on the upper surface of the electric battery 29 supported by the vertical pipe 28 of the bicycle. Like that.

As described above, in this embodiment, one lock A is used to lock the bicycle, the ON / OFF of the power switch B is linked to the locking operation, and the electric battery 29 is attached.
The removal lock lever 23 can be locked and released .

It should be noted that the form of the lock employed in practicing the present invention is not limited to the illustrated embodiment, and it goes without saying that it can be changed in accordance with the gist of the present invention.

[0027]

According to the electric bicycle lock of the present invention constructed as described above and used as described above, the lock operation of one lock attached to the bicycle and the power supply following the lock lever are performed. The switch automatically switches to OFF, preventing you from forgetting to turn off the switch when you leave your bicycle.The unlocking operation automatically switches the power switch from OFF to ON, so you can operate the hand switch when necessary. The battery can be used as before, and the use of the electric bicycle can be done smoothly.

Further, the lock for an electric bicycle according to the present invention
Locking lever of the lock lever for attaching and detaching the lee
To lock and release the lock lever for lock operation.
Linked to prevent battery theft
It is no longer necessary to provide a special lock, and theft of the battery
It can also prevent difficulties. Also, release the lock lever
The lock always locks the bicycle before and after charging the terry
Good stability during battery removal operation
No. The present invention has such excellent effects as described above.
