Abstract
A hatch assembly for a marine vessel included a slam latch and a frame and a cover having the slam latch disposed therein. The slam latch includes a housing having inner and outer portions and a pivotal handle for rotation between open and closed positions. A reciprocal fastening element including a second cam surface is adapted to engage the frame for retaining the cover against the frame. A spring biases the handle into a closed position and together with the first cam surface maintains the handle in an opened position when the handle is rotated through a predetermined angle. The latch also includes a push rod for converting the rotation of the handle to the reciprocal movement of the fastening element. The latch also includes a pair of seals to prevent water from passing through the latch.
Claims12
A slam action latch for mounting in an aperture of a hatch cover for releasably retaining the cover against a corresponding frame, said latch comprising a housing having inner and outer portions and a pivotal handle pivotally attached to said housing and being rotatable between an opened and a closed position, reciprocal fastening means including a cam surface, said reciprocal fastening means engaging the frame for retaining the cover against the frame when the handle is rotated to a closed position, biasing means for biasing said handle in a closed position and means for retaining said handle in an open position, said latch assembly including a push rod for engaging said cam surface to thereby transmit rotational movement of said handle to reciprocal movement of said fastening means, a first seal between said push rod and said inner portion of said housing and a second seal between said outer portion of said housing and a hatch cover whereby the two seals prevent water from passing through the slam action latch.
A slam latch assembly for mounting in an aperture in a marine hatch cover for releasable retaining the cover against a corresponding frame, said slam latch assembly comprising a housing having a first portion including an outer surface and a recessed inner surface and a second portion formed integrally with said first portion and having an outer surface, said first portion defining a first passageway and a second passageway connecting said first passageway and said recessed inner surface of said first portion, and a pivotal handle pivotally attached to said housing and disposed within said recessed inner surface, said handle being rotatable between an open and a closed position, and reciprocal fastening means including a cam surface and an inclined striker element disposed in said first passageway with said striker element extending outwardly therefrom for engaging a corresponding frame member to retain a cover against the frame when said handle is in a closed position, and means for retaining said handle in an open position, said hatch assembly including a spring and a spring biased push rod for contacting said cam surface to thereby convert the rotational movement of said handle to reciprocal movement of said fastening means, a first seal between said push rod and said second passageway and a second seal between said outer surface of said second portion of said housing and a hatch cover whereby the two seals prevent water from passing through the slam action latch.
A hatch for a marine vessel including a frame defining an opening for fitting within an aperture within a vessel and a hatch cover rotatably mounted on said frame for opening and closing said hatch, said cover including a first recessed portion and a second recessed portion within said first recessed portion, said recessed portion including an inner surface and defining an opening extending through said cover, and a slam latch including a housing having a first portion including an outer surface and a recessed inner surface and a second portion formed integrally with said first portion and having inner and outer surfaces, said first portion of said housing disposed in said first recessed portion of said cover with said second portion of said housing extending through said opening defined by said second recessed portion, a pivot disposed in said first portion of said housing and a handle pivotally attached to said housing by said pivot and being rotatable between an open and a closed position, reciprocal fastening means including a cam surface, said reciprocal fastening means engaging said frame for retaining the cover when the handle is rotated to a closed position, a spring for biasing said handle in a closed position and means including said spring for retaining said handle in an open position, said slam latch including a push rod for contacting said cam surface to thereby convert rotational movement of said handle to reciprocal movement of said fastening means, a first seal between said push rod and said inner surface of said second portion of said housing and a second seal between said outer surface of said second portion of said housing and said second recessed portion of said cover whereby water is prevented from passing through said latch assembly.
