Abstract: A frame includes sliding panels to cover an opening of a cabinet. The panels are mounted to interlocking stiffeners. Each of the interlocking stiffeners includes a base portion that forms a channel to receive a forward leading edge or a rear leading edge of the panels. The interlocking stiffeners share forces between the panels. A latch assembly may also be engaged to the interlocking stiffener attached to the forward leading edge of the panel. The latch assembly includes a protruding or projecting portion, such as a bullnose, that positions the latch assembly with respect to a side frame member. During a closing operation, the protruding portion enters a channel of the side frame member. The protruding portion engages with the channel of the side frame member, which results in proper alignment for the latch assembly.

Abstract: Frames having sliding panels to cover an opening of the cabinet are described. The panels are mounted to interlocking stiffeners. The interlocking stiffeners include a base portion that forms a channel to receive a leading edge of the panel. The interlocking stiffeners may be positioned on a forward leading edge and a rear leading edge of the panels. The interlocking stiffeners share forces across an adjacent panel and stiffener. A latch assembly may also be engaged to the forward edge of the panel. The latch assembly includes a channel to receive the forward edge. The latch assembly includes a protruding or projecting portion, such as a bullnose, that positions the latch assembly. During a closing operation, the protruding portion enters a channel of a side frame member. The protruding portion engages with the channel of the side frame member, which results in proper alignment for the latch assembly. The latch may include a striker and pawl assembly having a negative angle that resists opening forces.
