Rowing machine exercise device

A rowing machine exercise device comprising:

• a rowing machine frame having a forward support base approximate a forward end of the rowing machine frame and a rear support base approximate an opposite end of the rowing machine frame;
• a resistance mechanism mounted to the rowing machine frame and operatively coupled to at least one hand grip providing resistance of the at least one hand grip moving forward or rearward with respect to the rowing machine frame;
• at least one foot support mounted to the rowing machine frame;
• and
• a seat mounted for reciprocating movement along the rowing machine frame towards and away from the at least one foot support;
• wherein the rear support base is vertically adjustable and includes,
• an outer vertical support beam coupled to and extending down from the rowing machine frame, having a vertical channel extending upward therein from a bottom of the outer vertical support beam and having a latch pin hole extending through a wall of a bottom portion of the outer vertical support beam,
• an inner vertical support beam received in a telescoping manner within outer support beam through the bottom of the outer support beam, the inner vertical support beam having a plurality of adjustment holes uniformly spaced along a vertical line in an outer wall of the inner vertical support beam, the vertical line being horizontally aligned with the latch pin hole in the outer vertical support beam, and
• a latch pin assembly mounted to the outer vertical support beam, the latch pin assembly including a latch pin biased to extend through the latch pin hole and any of the plurality of adjustment holes that are vertically aligned with the latch pin hole, and the latch pin assembly including an actuating tab that overcomes a bias to pull the latch pin from the latch pin hole and the any of the plurality of adjustment holes that are vertically aligned with the latch pin hole when actuated;
• wherein the latch pin assembly includes a lever pivotally mounted to the outer vertical support beam;
• wherein the lever has an upper horizontal segment that includes the actuating tab, an opposite lower horizontal segment that includes the latch pin, and a vertical segment connecting the upper horizontal segment and the lower horizontal segment;
• and
• wherein the latch pin assembly includes a pivot pin positioned at an intersection of the upper horizontal segment and the vertical segment.

A rowing machine exercise device comprising:

• a rowing machine frame having a forward support base approximate a forward end of the rowing machine frame and a rear support base approximate an opposite end of the rowing machine frame;
• a rewinder mounted to the rowing machine frame;
• a pull rope attached to the rewinder at a first end and attached to a pull bar at an opposite end;
• at least one foot rest panel mounted to the rowing machine frame;
• and
• a seat mounted for reciprocating movement along the rowing machine frame towards and away from the at least one foot rest panel;
• wherein the rear support base is vertically adjustable and includes,
• an outer vertical support beam having a vertical channel extending therein and having a latch pin hole extending through a wall of a the outer vertical support beam,
• an inner vertical support beam received in a telescoping manner within outer support beam, the inner vertical support beam having a plurality of adjustment holes uniformly spaced along a vertical line in an outer wall of the inner vertical support beam, the vertical line being horizontally aligned with the latch pin hole in the outer vertical support beam, and
• a latch pin assembly mounted to the outer vertical support beam, the latch pin assembly including a latch pin biased to extend through the latch pin hole and any of the plurality of adjustment holes that are vertically aligned with the latch pin hole, and the latch pin assembly including an actuating tab that overcomes a bias to pull the latch pin from the vertically aligned latch pin hole and the any of the plurality of adjustment holes that are vertically aligned with the latch pin hole when actuated;
• wherein the latch pin assembly includes a lever pivotally mounted to the outer vertical support beam;
• wherein the lever has an upper horizontal segment that includes the actuating tab, an opposite lower horizontal segment that includes the latch pin, and a vertical segment connecting the upper horizontal segment and the lower horizontal segment;
• and
• wherein the latch pin assembly includes a pivot pin positioned at an intersection of the upper horizontal segment and the vertical segment.
