As shown in the embodiment shown in FIGS. 1A and 1B, the chain lock 900 of the present invention includes a columnar lock body 100 and a chain belt 333. More specifically, the appearance of the columnar lock body 100 assumes a columnar shape, and is preferably a cylinder. The cylindrical lock body 100 also has an axis 401. The axis 401 is preferably a central axis of the cylindrical lock body 100 and extends through opposite end faces of the cylindrical lock body 100. In various embodiments, however, the axis 401 can be a non-central axis that extends through the opposite end faces of the cylindrical lock body 100. The column lock body 100 includes a lock core 103 disposed therein, a lock body side 102, and a lock hole 101. The chain belt 333 has a first end 311 and a second end 391. The first end portion 311 is coupled to the columnar lock body 100. The second end portion 391 can be inserted into the lock hole 101 and can be locked via the lock core 103.

1A and 1B, when the second end 391 of the strap 333 is not locked, the strap 333 can be folded into the lock body side 102 in a folded manner. When the chain belt 333 abuts against the lock body side 102, the extension direction of the chain rod 300 is substantially the same as the direction in which the axis 401 of the columnar lock body 100 extends. In other words, the extending direction of the link 300 at this time is substantially parallel to the extending direction of the axis 401 of the columnar lock body 100. Viewed from a different angle, when the second end 391 of the strap 333 is not locked, the strap 333 can be engaged with the lock side 102 in a manner that folds along the longitudinal section of the cylindrical lock body 100. In other words, when each of the links 300 abuts toward the lock body side 102, the extension direction of the link 300 is substantially parallel to the longitudinal section of the column lock body 100.

Based on the above, the chain lock 900 of the present invention can reduce the storage volume, thereby solving the problems described in the prior art. On the other hand, the columnar lock body 100 is preferably long columnar. The chain lock 900 of the present invention is folded over the chain belt 333 based on the long cylindrical shape of the columnar lock body 100 and the extending direction of the elongated chain link 300 being substantially the same as the extending direction of the axis 401 of the columnar lock body 100. In the folded state of the lock body side 102, the overall shape can be substantially elongated, which is advantageous for being stored in an elongated storage space such as a bicycle bottle cage. Further, by appropriate design and manufacture, the chain lock 900 of the present invention has a width in the lateral direction (the cross-sectional direction of the columnar lock body 100) and a longitudinal direction (the direction in which the axis of the columnar lock body 100 extends) when the chain lock 900 of the present invention is in the folded state. Can be roughly equal to common The diameter and height of the bicycle kettle allow it to be stored directly in the bicycle bottle cage without the need for additional mounting brackets.

The manner in which the novel chain lock 900 is used is further explained below.

In the embodiment shown in FIGS. 1A and 1B, among the plurality of links 300 connected as the chain belt 333, one of the links 310 has a first end portion 311. The first end portion 311 is coupled to the columnar lock body 100, preferably to the lock body side 102, and more preferably to the connection portion 110 disposed on the lock body side 102. On the other hand, of the plurality of links 300 of the chain belt 333, the link 390 with respect to the other end of the link 310 has a second end portion 391.

2A to 2F, the link 300, which is not directly connected to the column lock body 100, that is, the chain rod 310, can be pulled away from the column lock body 100 by the user and extended into the lock. In the object (such as the pedal wheel frame). Then, as in the embodiment shown in FIGS. 3A and 3B, the second end portion 391 is inserted into the lock hole 101, and the second end portion 391 is restricted from the lock hole 101 by the lock core 103.

More specifically, the second end portion 391 is annular, and the lock core 103 may have elements such as a lock shaft. When the lock core 103 is in an unlocked state, for example, after the user unlocks the key, or the lock lock is unlocked by the user, the lock shaft can move in the column lock body 100, and when the lock core 103 is in the lock state The movement of the lock shaft in the column lock body 100 is limited. The construction of the above locks is a matter of fact, and will not be repeated here. When the second end portion 391 is inserted into the lock hole 101, the lock shaft of the lock core 103 can be restricted from leaving the lock hole 101 by passing the lock shaft of the lock core 103 through the annular second end portion 391, thereby achieving the purpose of locking. However, in different embodiments, the second end portion 391 is not limited to a ring shape, and may also be a hook shape, or only a positioning hole may be provided for the lock shaft to be inserted. On the other hand, if the lock is to be unlocked, only the lock core 103 needs to be unlocked, the movement limit of the lock shaft is released, the lock shaft can be separated from the second end portion 391, and the second end portion 391 can be disengaged from the lock hole 101. Unlock the lock.

As shown in the embodiment shown in FIGS. 3A and 3B, the keyhole 101 is disposed at one end of the columnar lock body 100. The lock core 103 is a number lock, and the lock body side 102 exposes the word lock wheel 200. By this arrangement, when the chain lock 900 of the present invention is in the folded state, the chain belt 333 can block the character wheel 200, reducing the chance of being damaged by the collision. On the other hand, the column lock body 100 can be provided with a switch device 120 at the other end of the lock hole 101. When the word wheel 200 is in the unlocking number, the operation locks the lock core 103 on and off.

The lock core 103 is not limited to a number lock, and other types can be used. As shown in Figure 3C In the illustrated embodiment, the lock core 103 is a key lock core, and the column lock body 100 is provided with a key hole 104 into which the key 210 of the key lock core is inserted with respect to the other end of the lock hole 101.

In order to fold the chain belt 333 against the side surface 102 of the lock body, the extending direction of the chain rod 300 is substantially the same as the extending direction of the axis 401 of the columnar lock body 100, that is, the longitudinal direction of the chain rod 300 along the columnar lock body 100. The manner of folding is coordinated to the side 102 of the lock body, and at least one of the links 300 preferably has a structure other than a flat plate. In the embodiment shown in FIGS. 1A to 3C, at least one of the links 300 has a bent structure. The so-called bent structure can be regarded as a plurality of flat sheets which are connected to each other and have an included angle. In the embodiment shown in Figures 4A to 4C, at least one of the links 300 has a twisted configuration. For example, the link 310 has a twisted configuration and the link 390 is a flat plate. The so-called torsion structure includes one end of the link twisted relative to the other end such that the surface of the link between the ends is curved. 5A to 5C, the link 300, which is not directly coupled to the column lock body 100, can be pulled away from the column lock body 100 by the user and into the article to be locked. Then, as in the embodiment shown in FIGS. 6A to 6C, the second end portion 391 is inserted into the lock hole 101, and the second end portion 391 is restricted from the lock hole 101 by the lock core 103. On the other hand, the link 300 may all have a structure other than a flat plate. As shown in the embodiment shown in Figures 7A through 9B, the chain bars 300 all have a twisted configuration.
