发明名称 Roller chock with a compound ratchet-type chain wheel
摘要 The invention relates to a device intended for manually lifting a mooring line which allows the user to rest between each pull on the mooring. It consists of a U-shaped support clevis 1 intended to be fixed to the deck of the boat, a compound chain wheel 2 is held on the clevis 1 by a pin 6. A ratchet 3 is fixed onto the clevis 1 by means of a pin 4. This ratchet prevents the chain wheel 2 from rotating in the boat mooring direction and thus blocks the mooring, which allows the user to rest without the part of the mooring which has just been raised on board returning to the water. <IMAGE>
