Patent ID: 7540254

Claim:
A stopper device ( 1 ) for chain ( 2 ) or wire, especially for locking in position an anchor chain, tow wire or mooring wire, wherein the stopper ( 1 ) consists of a pair of plates ( 3 , 4 ) which can be pivoted up from the deck ( 5 ) of a ship to be vertically positioned in a locked position relative to the deck, so that the plates form an angle (α) relative to each other and with a gap ( 6 ) between an area of adjacent plate edges on the pair of plates, wherein the gap ( 6 ) is configured to match the thickness of a chain link or a wire, wherein the pivoting movement of each plate is provided with the aid of a jack ( 7 ) in cooperation with a link mechanism ( 8 ; 9 ), and wherein the link mechanism ( 8 ; 9 ) in one end position causes a locking of the plate ( 3 ; 4 ) in the vertical position, characterised in that a first ( 10 ; 14 ) of the links in the link mechanism ( 8 ; 9 ) has an abutment area ( 11 ) designed to cooperate with a controllable, reciprocating locking bolt ( 12 ′; 17 ′) for locking the first link ( 10 ; 14 ) and thus the link mechanism ( 8 ; 9 ) in said one end position.
