Adjustable lockable tandem slide for boat seat

An adjustable lockable tandem slide for a boat seat comprising:

• a) a pair of laterally spaced elongated parallel first rigid members adaptable for attachment to a supporting surface;
• b) each of said first members having a pair of laterally spaced parallel elongated tracks;
• c) one of said first members having a side wall extending vertically upward from its track, said side wall containing longitudinally spaced detent holes;
• d) a pair of laterally spaced elongated second rigid members adaptable for attachment to the underside of a boat seat;
• e) each of said second members having laterally spaced vertical side walls and outward extensions from said side walls defining rails slidably engaging the tracks of said first members;
• f) a locking pin for engaging the detent holes in the side wall of said one first member, said pin slidably resting in opposite facing holes in both side walls of one of said second members;
• and
• g) a lever arm located between the side walls of said one second member and pivotally attached to a side wall of said one second member, said lever arm having a handle end extending longitudinally outward at one end of said one second member, said lever arm coupled to said locking pin to move said locking pin out of engagement with the detent holes of said one first member.

An adjustable lockable tandem slide for a boat seat, comprising:

• a) at least a pair of laterally spaced sets of slidably engaged rigid members, each set having an upper member adaptable for attachment to the underside of a boat seat and a lower member adaptable for attachment to a supporting surface;
• b) the lower member of each set having elongated parallel side walls with inward opposite facing slots defining tracks and an elongated strip extending upward from one of said side walls, said strip having longitudinally spaced detent openings;
• c) the upper member of each set having elongated parallel side walls with lips extending outward from said side walls, said lips slidably engaging the tracks of the respective lower member;
• d) each of said upper members having a horizontal locking pin slidably resting in opposite facing holes in the side walls located to engage the detent openings in the slidably engaged lower member;
• e) lever arms located between the side walls of each of said upper members, the lever arms having a handle end extending out one end of the upper members, said lever arms coupled to respective locking pins to selectively move said locking pins out of engagement with their respective detent openings when the handle end is moved laterally, said lever arms connected together to move laterally in unison.
