Abstract:
1. A component for regulating or modifying the effective length of round steel chains, in which at least two crossing slots are arranged in a basic body, form an insertion or pull-through opening for the respective chain in their crossing area, one of said slots being longer than the other, the respective longer slot being bounded outside the crossing area of the slots by two supporting zones which serve to support the curved end in each case of a chain link which follows a chain link inserted with its limbs into the longer of the two slots, the chain link which follows the chain link inserted into the longer of said two slots being securable by a blocking element against displacement into the area of the insertion or pull-through opening, characterized in that the blocking element comprises a pin ( 11 ; 33 ) that can be moved to and from and is provided on its circumference with at least one groove ( 14 or 15 ), in that the pin ( 11 ; 13 ) is held by a spring ( 10 ) in a first position, in which it projects with its cylindrical circumference into the end of the longer slot ( 12 or 13 ) in the crossing area of the slots ( 6 , 12 or 7 , 13 ), forming a stop that substantially fills this end and prevents displacement of the chain link ( 18 or 19 ) guided in the longer slot ( 12 or 13 ) into the crossing area of the slots ( 6 , 12 or 7 , 13 ), and in that the pin ( 11 ; 33 ) can be transferred counter to the action of the spring ( 10 ) holding the pin ( 11 ; 33 ) in the first position into a second position, in which its groove ( 14 or 15 ) forms the end of the longer slot ( 12 or 13 ) in the crossing area of the slots ( 6 , 12 or 7 , 13 ).
