Title:
FISH HATCH COVER
Document Type and Number:
Japanese Patent JPS63247192
Kind Code:
A
Abstract:
PURPOSE:To improve the loading efficiency of fish by connecting a cover body to a horizontally driven member via a parallel link and moving said cover body between a closing position and a housing position along an L-shaped guide formed on a hull. CONSTITUTION:As a cylinder 14 is extended, a pinion 13 is displaced forward along a rack 11 to make a cover body 3 which is connected to a connecting member 9 via a parallel link 7 slide forward. In this case, the parallel movement of the rack 11 and the cover body 3 is guided by wheels 4, 8 which roll inside L-shaped guide grooves 6, 10 respectively. When the wheel 4 enters from the horizontal part 6A of the guide groove 6 to the vertical part 6B, the cover body 3 is pushed upward while maintaining a horizontal condition and arrives at a closing position. And, as the cylinder is contrarily contracted, the cover body 3 is housed below an upper deck. Accordingly, the loading/unloading of fish can be easily carried out.
