Description

[0001]
TECHNICAL FIELD OF THE INVENTION
According to the present invention, two locking mechanisms are provided at the front and rear of an arc-shaped locking rod, respectively, and two locking mechanisms for locking the two front and rear locking hooks are provided on both sides of a hollow and arc-shaped locking case. Regarding the bicycle ring lock provided near the opening, a flexible lock rod is attached to the lock body separately from the arc-shaped lock rod, and the lock rod is locked together with the arc-shaped lock rod. It is characterized by the following.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. Hei 8-268358 discloses a bicycle ring lock in which the locking rod of the ring lock is locked at two places.
[0003]
[Problems to be solved by the invention]
Since the ring lock of the prior application is locked by two lock mechanisms, the lock is not unintentionally unlocked, and the safety of the lock is improved, and the anti-theft effect is improved. However, it is one ring lock. For users who want a more secure lock, a lock with a flexible and long lock rod, such as a chain lock or a wire lock, may be used in combination with a lock such as a fence or street tree. It has become more common to anchor them to fixed objects.
[0004]
As described above, when another lock with a flexible and long lock rod is used together, the safety of locking is enhanced, but it is necessary to purchase a wire lock etc. separately from the lock attached at the time of purchase It is expensive. In addition, the chain lock and the wire lock have inconvenience in carrying when not in use, and when used together, there is a complicated operation in which the unlocking operation is doubled.
Therefore, the problem to be solved is to develop a ring lock for bicycles that enables this kind of lock to be used more firmly, that is not inconvenient to carry when not in use, and that is easy to unlock. Had become.
[0005]
[Means for Solving the Problems]
Therefore, the present invention provides two locking mechanisms for providing two locking portions at the front and rear of an arc-shaped locking rod and individually locking the two locking portions, respectively. In a bicycle ring lock provided near each of the two openings of the main body, a fixed end of a flexible lock rod is attached to an appropriate position of the lock main body, and a lock rod portion at the tip of the flexible lock rod is attached to the inside of the lock mechanism. It is configured to be inserted into a lock hole provided near one side and to be locked together with the arc-shaped lock rod by a hook plate attached to the lock mechanism, so that one ring lock is locked at three places. The present invention provides a bicycle ring lock characterized in that:
[0006]
This ring lock can lock an arc-shaped lock rod with two lock mechanisms, and can also use a flexible lock rod attached thereto to connect a bicycle to a nearby tree or fence.
[0007]
And since the present ring lock is provided integrally with a flexible lock comparable to a chain lock or a wire lock, it is not expensive compared to a case where it is separately purchased. Since the flexible locking rod is unlocked together with the arc-shaped locking rod, the operation is not complicated, and it is convenient to carry.
The present invention has solved the above-mentioned problems as described above.
[0008]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
As shown in the drawings, the bicycle ring lock L includes an arc-shaped hollow lock case 1 and an arc-shaped lock rod 3 pulled by a pulling spring 2 in an arc-shaped hollow lock case 1. Two lock mechanisms 4 and 5 are provided near the opposing right and left openings 1a and 1b, respectively.
[0009]
As shown in FIG. 2, the arcuate locking rod 3 is locked by a hook plate 4 ′ 5 ′ attached to the inner ends of the two locking mechanisms 4, 5 as shown in FIG. 2. 6 and 7 are provided in two places in front and back.
[0010]
As shown in FIG. 1, the lock case 1 is integrally provided with a flexible lock rod 8 having a fixed end 9 fixed in an upper part of the case and wound up in a coil shape, and provided at a free end of the lock rod 8. The locking rod portion 10 is inserted into a locking hole 11 opened near the locking mechanism 4 on the right side in the drawing, and is superimposed on the back surface of the hook plate 4 'at the inner end of the locking mechanism 4 as shown in FIG. Locked by the hook plate 12.
[0011]
A hook plate 12 for locking the lock rod portion 10 has a front edge locked by a locking claw 13 provided on a side surface of a hook plate 4 ′ superposed on the upper surface, and is urged by a spring 14 from a rear end. Following the unlocking operation of the hook plate 4 '(right rotation in the figure), the hook plate 4' retreats to open the pseudo-beaded tip portion of the lock rod portion 10 which is hooked at the forked portion of the tip.
[0012]
When the flexible lock rod 8 is used, it is unlocked as described above, the flexible lock rod 8 is extended and wound around a fixed object, and the lock rod 10 is inserted into the lock hole 11 again. As in the case of the wire lock described above, the hook plate 12 is retracted against the spring 14 and then repositioned to keep the lock rod 10 in the locked state.
[0013]
The two lock mechanisms 4, 5 are unlocked by a common key (not shown), and the hook plates 4 ', 5' attached to the lock mechanisms 4 ', 5' are all the same as in the known ring lock. The lock mechanisms 4 and 5 are automatically biased in the locking direction to automatically engage with the locking portions 6 and 7 that rotate while permitting the locking rod 3 to pass in the locking direction, and open the locking mechanisms 4 and 5. The lock lever 3 is retracted by the locking operation to allow the locking rod 3 to return.
[0014]
Since the ring lock L configured as described above is provided with the flexible lock rod 8 integrally with the lock case 1, the circular lock rod 3 can be locked in two places, and the flexible lock rod 3 can be locked if necessary. By using the lock 8, the bicycle can be fixed to a fixed object within the range of the length of the flexible lock rod 8 similarly to the conventional chain lock.
Further, since the unlocking of the flexible lock rod 8 is performed simultaneously with the unlocking operation of the hook plate 4 'of the one lock mechanism 4, no labor is required.
In the drawing, reference numeral 15 denotes a knob for locking the arc-shaped lock rod 3, and 16 denotes a guide groove thereof.
[0015]
Since the lock mechanisms 4 and 5 used in the embodiment are conventionally known lock mechanisms used in the bicycle ring lock of the prior application, detailed description and illustration thereof are omitted.
In addition, it goes without saying that the design of the locking mechanism and the hook plate 12 for locking the flexible locking rod 8 can be arbitrarily changed in accordance with the gist of the present invention.
[0016]
【The invention's effect】
As described above, according to the present invention, the locking rod of the bicycle ring lock can be locked by the two locking mechanisms, and if it is desired to further secure the locking, the flexible locking rod integrally attached to the lock case is provided. The bicycle can be tied to a nearby tree or fence by using, so that there is no need to prepare a special wire lock or the like.
[0017]
In addition, the ring lock of the present invention is provided with a flexible lock comparable to a chain lock or a wire lock, and thus is not expensive compared to a case where it is separately purchased. Since the flexible locking rod is unlocked together with the arc-shaped locking rod, the operation is not complicated and the carrying is convenient.
The present invention has excellent effects as described above.
