US 2023/0417082 A1 · CHAIN LOCK AND CHAIN FOR A CHAIN LOCK

Abstract

A chain lock comprises a lock body and a chain lockable to the lock body. This chain comprises a serial arrangement of consecutive links coupled to one another via a respective articulated joint and pivotable relative to one another about a joint axis, which is parallel to a normal direction, of the respective articulated joint. The arrangement is foldable into a compact storage configuration in which, at each of the articulated joints, the links coupled to one another via the respective articulated joint are pivoted relative to one another about the joint axis of the respective articulated joint such that they enclose the smallest possible angle of their relative pivotability. A pulling device extends along said arrangement, by way of which a first end of the arrangement and a second end of the arrangement opposite thereto are pullable toward one another to bring the arrangement into the compact storage configuration.

A chain lock comprising a lock body and a chain that comprises a serial arrangement of consecutive links that are coupled to one another via a respective articulated joint between one another and pivotable relative to one another about a joint axis, which is parallel to a normal direction, of the respective articulated joint,

wherein the arrangement is foldable into a compact storage configuration in which, at each of the articulated joints, the two links coupled to one another via the respective articulated joint pivoted relative to one another about the joint axis of the respective articulated joint to such an extent that they enclose the smallest possible angle of their relative pivotability,
wherein the links of the arrangement at least partly adopt the same position along the normal direction,
and wherein the lock body has a locking receiver which is configured to receive a section of the chain and comprises a locking mechanism by way of which said section of the chain can be secured against a departure from the locking receiver.

A chain for a chain lock, the chain comprising:

a serial arrangement of consecutive links that are coupled to one another via a respective articulated joint between one another and that are pivotable relative to one another about a joint axis, which is parallel to a normal direction, of the respective articulated joint,
wherein the arrangement is foldable into a compact storage configuration in which, at each of the articulated joints, the links coupled to one another via the respective articulated joint are pivoted relative to one another about the joint axis of the respective articulated joint to such an extent that they enclose the smallest possible angle of their relative pivotability, and
wherein the chain comprises a pulling device which extends along said arrangement and by way of which a first end of the arrangement and a second end of the arrangement opposite thereto are pullable toward one another such that the arrangement is brought into the compact storage configuration by the pulling device.
