Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bicycle lock in which two bicycle locks respectively attached to a front wheel and a rear wheel of a bicycle can be simultaneously locked or unlocked. A circle lock is used for front and rear locks, and a lock for both circle locks is provided. A flexible rod is connected to each other, and the flexible rod is separately locked and unlocked in a lock case provided with a base end of the flexible rod separately.
[0002]
[Prior art]
A bicycle usually has one lock attached. Examples of bicycle locks that can be remotely operated at the handle portion with a flexible rod for locking and unlocking a single lock include Japanese Utility Model Publication No. 6-29179 and Japanese Utility Model Publication No. 7-6442.
In addition, in the prior application of the present applicant, the lock rod of one lock and the lock rod of the other lock are connected by a flexible rod so that the unlocking of one lock is transmitted to the lock of the other lock. Japanese Patent Application No. 8-330448 is available as a bicycle lock.
[0003]
[Problems to be solved by the invention]
If there is anxiety with one lock attached to the car body, other chain locks are also used, but in that case, it is necessary to perform the operation of locking and unlocking twice each time. So it becomes annoying. On the other hand, the bicycle lock of Japanese Patent Application No. 8-330448 in which one circle lock is interlocked with the other circle lock is advantageous, but generally the operation side of the circle lock is the left side of the vehicle body, The disadvantage of being difficult to operate for people getting on and off the right side has not been resolved.
[0004]
For this reason, the problem to be solved by the present invention is to solve the inconvenience of locking and unlocking by interlocking the two front and rear circle locks, and the operation that is different from the right down person and the left down person It is to provide a bicycle lock that can be used.
[0005]
[Means for Solving the Problems]
Therefore, the present invention attaches a bicycle circle lock to the frame along the front wheel and the frame along the rear wheel of the bicycle, respectively connects the flexible rods to the locks of the front and rear circle locks, and connects the base ends of the two rods. One of the two can be folded back in the lock case and introduced into the lock case attached along the upper area of the bicycle seat pipe , and the proximal ends of the two introduced rods are inserted into the lock case. The above-mentioned front and rear circle locks are connected via a flexible rod which is provided with a slide freely and is connected to a plate with an operation lever facing outside the case and pulled by one-way movement of the plate. Are moved to the locking position, and the hook plate moved to the locking position is locked to the locking lever of the locking mechanism attached to the lock case. At the same time lock the circle lock, it is to be able to unlock operation.
[0006]
According to the present invention, the two circle locks attached to the front and rear of the bicycle are locked and unlocked by the lock case attached to the seat pipe at the center of the vehicle body. Will also be able to operate.
In addition, both front and rear wheels can be locked with a single lever operation, providing a sufficient anti-theft effect as well as operability.
[0007]
【Example】
The bicycle lock according to the present invention has a circle lock 2 attached to the vehicle body b along the front wheel 1 of the bicycle B and a circle lock 4 attached to the vehicle body b ′ along the rear wheel 3 as shown in the figure. .
Both circle locks 2 and 4 are not provided with a locking mechanism for locking the lock rod. A flexible rod 7 with a proximal end drawn out from the body of the circle locks 2 and 4 is connected to the lock rod 6 fitted in the circle locks 2 and 4 together with the restoring spring 5.
[0008]
The flexible rods 7 are each covered with a sheath 8 and introduced into a lock case 10 attached to the seat pipe 9 of the bicycle B as shown in FIG.
One of the two flexible rods 7 introduced into the lock case 10 (the rod 7b connected to the lock of the circle lock that locks the rear wheel) is wound around the roller 11 provided in the lock case 10 It is provided to travel.
[0009]
The base ends of the two flexible rods 7 are aligned and fixed to a cover plate 12 that is freely slidable in the lock case 10, and slides in one direction of the cover plate 12 (downward in FIG. 1). The lock rod 6 is pushed out to the locked position as indicated by an imaginary line in FIG.
[0010]
The sliding of the saddle plate 12 is performed by moving the operation lever 13 that protrudes from the side surface of the lock case 10 to the imaginary line position shown in FIG. The slat 12 moved to the predetermined locking position is locked when the locking lever 15 of the locking mechanism 14 attached to the lock case 10 is fitted into the locking hole 16.
[0011]
In this embodiment, since a conventionally known cylinder lock mechanism is adopted as the lock mechanism 14, detailed description and illustration thereof are omitted.
The locking mechanism 14 is locked by the locking lever 15 biased by the coil spring 16 being fitted into the latching hole 16 on the side surface of the flange plate 12, and the retraction of the locking rod 6 via the flexible rod 7 to the restoring spring 5. This is done by blocking against it. Further, unlocking is performed by the locking lever 15 coming out of the locking hole 16 following the rotation operation of the key 19 inserted into the key hole 18.
[0012]
In the figure, reference numeral 20 denotes a circle lock and a base for drawing out the flexible rod 7 of the lock case 10.
[0013]
【The invention's effect】
As described above, the two circle locks provided at the front and the back and the lock case attached to the seat pipe are connected by a flexible rod so that the lock can be unlocked simultaneously by sliding the saddle plate provided in the lock case. According to the invention bicycle lock, both circle locks can be operated on the seat pipe at the center of the bicycle. Therefore, the bicycle lock can be operated from either the left or right side of the bicycle and is convenient to use. In addition, since the front and rear wheels can be locked with a single lever operation, the lock has a sufficient anti-theft effect as well as improved operability.
The present invention has excellent effects as described above.
