A support member secured to the mounting member is moveable between a stowed and support positions. The support member includes a pair of legs defining at least in part a base of the support member. Each of the legs is selectively reconfigurable between a first configuration in which the leg has a relatively shorter length and a second configuration in which the leg has a relatively longer length. When the legs are in the relatively shorter configuration, the stand may be used to support the structure in an inclined position on a work surface. When the legs are in the longer configuration, the stand may be used to retain the structure in self-supporting configuration so the structure can support itself upright on the work surface.06-04-2009
20090169287RING MECHANISM BIASED TO CLOSED AND LOCKED POSITION - A ring binder mechanism that retains loose-leaf pages and has ring members that readily lock together in a closed position, preventing accidental opening of the ring members and loss of pages. The mechanism comprises a housing that supports two hinge plates for pivoting motion that brings the ring members to either an open position or the closed position. The mechanism further comprises a control structure supported by the housing for causing the pivoting motion of the hinge plates. A spring plate is engageable with the control structure for urging the control structure to move toward a position blocking pivoting motion of the hinge plates when the ring members move to the closed position.07-02-2009
