Abstract

A chain lock, in particular for a two-wheeled vehicle, comprises a lock body and a chain lockable to the lock body. The chain comprises a serial arrangement of successive links which are coupled to each other by respective articulation joints between each other and which are pivotable relative to each other about joint axes of the respective articulation joints, which joint axes are parallel to the normal direction. The arrangement is foldable into a compact storage configuration, wherein at each of the articulation joints, two links coupled to each other by the respective articulation joint pivot relative to each other about the joint axis of the respective articulation joint to the extent that they encompass the smallest possible angle within their range of relative pivotability. The chain further comprises a pulling device extending along the arrangement, by means of which the first end of the arrangement and the second end of the arrangement opposite thereto can be pulled towards each other, such that the arrangement is brought into a compact storage configuration by the pulling device.

Description

Chain lock and chain for a chain lock Technical Field The present invention relates to a chain lock, in particular a two-wheeled vehicle chain lock, and to a chain for a chain lock, in particular a chain for a two-wheeled vehicle chain lock. Background It is known to connect a corresponding object to an immovable object by means of a lock in order to secure a two-wheeled vehicle or other movable object against theft. Thus, locks typically have an elongated latch element that is desirably guided through an opening of an object to be secured and through or around an immovable object and then received and locked onto the lock body of the lock, thereby forming an annular closed and then unlockable structure that is reopened in a conventional manner only by an associated code such as a key or code. For example, the latch element may be a typical U-shaped closure collar of a collar lock (hoop lock). Such a closure cuff is rigid. For this reason, it may have a very limited length so as not to be too cumbersome to simply carry. This results in that the movable object to be fixed must be positioned very close to the immovable object to which it is to be fixed in order to be able to be locked to the immovable object by means of the ferrules. A more flexible positioning of the object to be secured can be achieved by a lock with a longer latching element, which, however, is preferably not rigid or at least not entirely rigid, but rather foldable to enable transport in a compact (compact) shape. Such a latching element may be formed, for example, by a rope, cable rope or chain. In addition to flexible applicability, it is naturally also important that the latching element is designed to be as safe as possible to prevent separation or breakage. Cable locks, in particular helical cable locks, can have particularly long latching elements, which can be made of wire rope (wire rope), for example, but generally do not provide particularly high security. In contrast, the use of an articulated chain made of inter-engaging round or oval articulated chains (LINK CHAIN) as latching element can provide a higher security, since the entire articulated chain is flexible, but the individual links (CHAIN LINK) can be rigid and can thus be made of a particularly hard material, such as hardened steel. However, the relatively high weight may be a disadvantage of the articulated chain as a latching element. The weight may have little effect on securing a heavy motorcycle. However, for bicycles in particular, for example, in particular, high-quality lightweight racing vehicles, in addition to high safety against prying open, weight saving is also important. In particular in this respect, the connecting rod lock (jointed bar lock) is particularly advantageous in that its latching elements are formed by rigid flat elongate links which are coupled to one another in an articulated manner and are arranged offset parallel to one another so that they can be folded like a folding ruler to form a compact package. Thus, these rigid connecting rods and the hinged joint between the connecting rods can provide high security against breakage while keeping the weight relatively low. In addition, the connecting rod lock can indeed have a longer length, in particular compared to the hoop lock, but can still be folded in a particularly compact manner and can thus be transported easily. But in order to be able to fold easily just as much as a folding ruler, the length of a single connecting rod cannot be too short and the number of connecting rods cannot be too large. This results in that the connecting rod arrangement may only have a polygonal course consisting of several straight segments, but cannot be guided around tight curves. Especially in narrow environments, for example when multiple bicycles are connected to a single lamppost, it is advantageous if the latching elements of the respective locks can also have a tightly curved course for particularly flexible use. Disclosure of Invention It is an object of the present invention to provide a chain lock, in particular a two-wheeled vehicle chain lock, and to provide a chain for a chain lock, in particular a chain for a two-wheeled vehicle chain lock, which can each be used in a particularly flexible manner, can be folded simply in a compact manner for transport, and thus at the same time has a high safety against damage and has a relatively low weight. This object is achieved by a chain lock having the features of claim 1 and by a chain having the features of claim 4. Advantageous embodiments of the invention emerge from the dependent claims, the description and the figures. The chain according to the invention is configured for a chain lock, in particular for a two-wheeled vehicle chain lock, so that it is particularly suitable for use as a latch element of the chain lock. For this purpose, the chains may be configured correspondingly, in particular at their respective ends or at least one end, for examp
