Support mechanism

A collapsible seat base, the seat base comprising:

• a base member adapted with means to reversibly interrelate the collapsible seat base with a support surface on its ventral face, and further adapted to provide at least two distinct movable connections for attaching additional elements to its dorsal face, and where a first movable connection is adapted to provide a movable connection to a first side member that allows the first side member to rotate along its radius and relative to the base member, and a second movable connection adapted to provide a compound movable connection to:
• i.) a second side member allowing it to rotate along its radius and relative to the base member;
• and, ii.) a slide-guide allowing it to rotate along its radius and relative to the base member;
• a support member adapted with means to receive a seat on its dorsal face, and further adapted to provide at least two distinct movable connections for attaching additional elements to its ventral face;
• where, a first movable connection is adapted to provide a movable connection to a second side member that allows the second side member to rotate along its radius and relative to the support member, and a second movable connection adapted to provide a compound movable connection to:
• i.) a first side member allowing it to rotate along its radius and relative to the support member;
• and, ii.) a slide allowing it to rotate along its radius and relative to the support member;
• a first side member adapted to receive at least two movable connections on opposing ends and where, a first movable connection is operatively connected to the base member by means of the base member's first movable connection, and a second movable connection is operatively connected to the support member by means of the support member's second movable connection;
• a second side member adapted to receive at least two movable connections on opposing ends and where, a first movable connection is operatively connected to the support member by means of the support member's first movable connection, and a second movable connection is operatively connected to the base member by means of the base member's second movable connection;
• a slide adapted at one end to receive a movable connection from the support member and where, the slide is operatively connected to the support member by means of the support member's second movable connection in such a fashion that allows a distal end to rotate relative to the support member;
• a slide-guide adapted at one end to receive a movable connection from the base member and operatively connected to the base member by means of the base member's second movable connection in such a fashion that allows a distal end of the slide-guide to rotate relative to the base member, and further adapted with means to support, orient and enclose a slide within the slide-guide while allowing the slide and slide-guide to move in substantially parallel but opposing directions;
• and,
• a collapsible seat base operably assembled as set forth;
• such that, when said base member is affixed to a support surface, and the device is in its lower resting configuration, the support member can be raised and rotated along a radius greater than 90 degree from its starting point with a simple hand motion and to an extent that movement of the slide through the slide-guide is not impeded by contact with the base member;
• wherein, said contact of slide with base-member sets the apparatus in a stable upright configuration.
