ASSEMBLY OF CHAIN STOPPER AND CHAIN, AND CHAIN STOPPER FOR USE THEREIN

摘要

An assembly of chain stopper and chain includes a housing, a vertically extending chain channel defined in the housing in which a chain is received and guided and two chain lockers positioned at opposite sides of the chain channel. Each chain locker pivots on a chain locker pivot axis between an inwardly rotated position engaging the chain and preventing a downward shift of the chain, and an outwardly rotated position allowing an upward shift of the chain. Each chain locker is biased towards its inwardly rotated position. Each chain locker pivot axis as a result of forces transmitted by the chain on the respective chain locker is displaceable from its original position to a stable second position in which the respective chain locker, in its inwardly rotated position, is not able to engage the chain in a manner for preventing a downward shift of the chain in the chain channel.

主权项

1. An assembly of chain stopper and chain, comprising a housing, a vertically extending chain channel defined in the housing in which a chain is received and guided and two chain lockers positioned at opposite sides of the chain channel, wherein each chain locker is pivotably mounted on a chain locker pivot axis for a rotation between an inwardly rotated position for engaging the chain and preventing a downward shift of the chain in the chain channel, and an outwardly rotated position allowing an upward shift of the chain in the chain channel and wherein each chain locker is biased towards its inwardly rotated position,
wherein each chain locker pivot axis as a result of forces transmitted by the chain on the respective chain locker is displaceable from an original position to a stable second position in which the respective chain locker, in its inwardly rotated position, is not able to engage the chain in a manner for preventing a downward shift of the chain in the chain channel and wherein the chain locker pivot axis is restrainable in its original position.
