Abstract
A folding bench has a first surface and first surface support girders. First and second support members are selectively positionable in an extended position, generally perpendicular to the first surface, and in retracted position, generally parallel and adjacent to the first surface. A second surface is selectively positionable in an extended position and in a retracted position. The second surface is connected to the first surface with a first mechanism and connected to the first support member with a second mechanism. A third mechanism is arranged to stabilize the support members in the first extended position and allows the support members to assume the second retracted position. A fourth mechanism secures the first and second support members in the second retracted position.
Claims18
A folding bench comprising:
- a first surface having first surface support girders;
- first and second support members selectively positionable in a first extended support position generally perpendicular to said first surface and in a second retracted support position generally parallel and adjacent to said first surface;
- a second surface selectively positionable in a first extended surface position forming a generally obtuse angle relative to said first surface and in a second retracted surface position generally parallel and adjacent to said first surface;
- said second surface connected to said first surface with a first mechanism and connected to said first support member with a second mechanism;
- and
- a third mechanism arranged to stabilize said support members in said first extended support position and allow said support members to assume said second retracted support position,
- wherein said third mechanism comprises support member stabilizing rods pivotally connected to said support members and having rod ends resembling fangs,
- and a channel member attached to said first surface and formed with openings accommodating said rod ends.

- said second surface connected to said first surface with a first mechanism and connected to said first support member with a second mechanism;
- and
- a third mechanism arranged to stabilize said support members in said first extended support position and allow said support members to assume said second retracted support position,
- where said support members are secured in said second retracted support position with a fourth mechanism,
- where at least one of said first support girders is formed with openings and said fourth mechanism comprises:
- first and second hooks attached to said first and second support members respectively;
- a locking unit attached to one of said first surface support girders with first and second pins having first and second springs respectively therebetween;
- said first and second pins passing freely through said openings in said at least one of said first surface support girders;
- wherein said first and second support members are secured in said second retracted position by depressing said lock unit, allowing said first and second support members to assume their respective generally parallel positions, and releasing said locking unit so that said first and second springs return said locking unit to bias said first and second hooks.
