Abstract
A pedestal assembly for a boat seat is disclosed which combines in a single lever adjustment the ability to raise and lower the seat as well as to lock or unlock the seat to permit clockwise and counterclockwise swivel action, as well as moving the seat fore and aft with respect to the pedestal. The lever is pulled up for vertical adjustments up or down. The lever is pushed down facilitating clockwise or counterclockwise pivoting about the pedestal of the seat. When the lever is released it is spring-biased to a neutral position. Depending on the configuration, the seat can be locked in one or more swivelled positions about the pedestal. The seat can be easily moved fore and aft with respect to the pedestal through the lever
Claims18
A pedestal assembly for a seat, comprising:
- a base;
- a tube having a longitudinal axis, said tube is moveably supported on to said base;
- a seat mount supported by said tube;
- a support member connected to the seat and movably mounted to said seat mount;
- a single lever on said seat mount and movable with respect to said tube and said support member into a plurality of position to accomplish at least two of the following movements:
- movement of said tube along its longitudinal axis, when the lever engages an actuating pin of a power cylinder which interconnects the base and the tube rotation of said seat mount about said longitudinal axis of said tube, when the lever disengages a recess in the tube, and translation of said support with respect to said seat mount when the lever disengages engagement grooves from a locking member of said support;
- said lever selectively preventing at least one of said movements while preventing at least one of said movements by occupying one of said plurality of positions;
- said lever directly selectively preventing at least one of said movements;
- in one of said positions.
A pedestal assembly for a seat, comprising:
- a base;
- a tube having a longitudinal axis, said tube is movably support on said base;
- a seat mount supported by said tube;
- a support member connected to the seat and movably mounted to said seat mount;
- a single lever on said seat mount and movable with respect to said tube and said support member to accomplish at least two of the following movements:
- movement of said tube along its longitudinal axis, when the lever engages an actuating pin of a power cylinder which interconnects the base and the tube rotation of said seat mount about said longitudinal axis of said tube, when the lever disengages a recess in the tube, and translation of said support with respect to said seat mount;
- when the lever disengages engagement grooves from a locking member of said support;
- said support member comprises a movable locking member releasably engageable to said seat mount;
- said locking member comprises a pivoting bar having at least one tooth;
- and
- said seat mount comprises at least one groove to selectively engage said tooth upon selective operation of said lever.
A pedestal assembly for a seat, comprising:
- a base;
- a tube having a longitudinal axis, said tube is movably supported on said base;
- a seat mount supported by said tube;
- a support member connected to the seat and movably mounted to said seat mount;
- a single lever on said seat mount and movable with respect to said tube and said support member to accomplish the following movements:
- movement of said tube along its longitudinal axis, when the lever engages an actuating pin of a power cylinder which interconnects the base and the tube rotation of said seat mount about said longitudinal axis of said tube, when the lever disengages a recess in the tube and translation of said support with respect to said seat mount;
- when the lever disengages engagement grooves from a locking member of said support;
- said lever accomplishing all of said movements;
- said power cylinder supporting said tube;
- said lever is operable into a first position to enable said longitudinal movement of said tube by actuation of said power cylinder and in a second position to enable said rotational movement of said seat mount by disengagement from said tube;
- said lever is operable in a third position where it does not actuate said power cylinder and where it is rotationally locked to said tube such that longitudinal movement of said tube and rotation of said seat mount cannot occur;
- said third position is between said first and second positions;
- said first, second, and third positions are reached by movement of said lever in a plane substantially parallel to said longitudinal axis;
- said lever movable into a fourth position in the same direction and beyond said second position to disengage said support member from said seat mount for translation of said support member with respect to said seat mount.
