Abstract
This invention relates to a portable expandable desk comprising a first substantially rigid flat surface member; a second substantially rigid flat surface member; a means for hingedly attaching the first surface member to the second surface member so that the first and second surface members are capable of folding together; and a means for bracing the first surface member and the second surface member in an unfold position wherein the bracing means comprises a gripping means to prevent the bracing means from inadvertently disengaging from the first or second surface member.
Claims12
A portable expandable desk article comprising a first substantially rigid flat surface member;
- a second substantially rigid flat surface member;
- a means for hingedly attaching the first surface member to the second surface member so that the first and second surface members are capable of folding together;
- and a means for bracing the first surface member and the second surface member in an unfolded position wherein the bracing means comprises a gripping means to prevent the bracing means from inadvertently disengaging from the first or second surface member wherein the width of the second surface member is greater than the width of the first surface member to provide a storage surface for storing the bracing means when the first and second surface members are in a folded position.
A portable expandable desk article consisting essentially of a first substantially rigid flat surface member;
- a second substantially rigid flat surface member that is longer in width than the first surface member;
- a hinge means for attaching the first surface member to the second surface member so that the first and second surface members are capable of folding together;
- a bracing means for bracing the first surface member and the second surface member in an unfolded position, that is stored on a portion of the second surface member that extends beyond the first surface member when the first and second surface members are in a folded position;
- a gripping means for preventing the bracing means from inadvertently disengaging from the first or second surface member;
- optionally a locking means for securing the first and second surface members in a folded position;
- optionally a means for retaining a writing implement;
- optionally a means for storing paper;
- and optionally a means for positioning and maintaining the desk article in an inclined state.
