Abstract
A layable seat includes front and rear paired supporting legs which are layably raised on a floor at two positions separated from each other in a back-and-forth direction, a seat member pivotably connected to the front paired legs, paired link levers each of which has one end pivotably connected to the corresponding one pivotal center of the seat member and the other end pivotably connected to the corresponding rear leg. The seat member is elastically held at its half-folded position by torsion coil springs, and has paired engaging pins which project sideward therefrom and engage the lower edges of the link levers to hold the seat member at its horizontal position against a user's weight.
Claims8
A layable seat comprising:
- supporting leg means which is adapted to be mounted on a floor surface to be pivotable between a raised position where the leg means is raised from the floor surface and a horizontally laid position where the leg means is horizontally laid along the floor surface;
- a seat member which is mounted on said supporting leg means to be pivotable between a horizontal position where the seat member extends substantially horizontally from said supporting leg means located at the raised position and a folded position where the seat member is raised substantially vertically to extend along said supporting leg means located at the raised position;
- urging means which is mounted on said supporting leg means and urges said seat member to a half-folded position between the horizontal and folded positions;
- and
- forcible moving means which is mounted on said supporting leg means and forcibly moves said seat member from the half-folded position to the folded position against an urging force of said urging means in response to the pivotal movement of said supporting leg means from the raised position to the horizontally laid position.
