Abstract

Some enclosures for data processors have a wide vertical opening that is covered by bifold panels. Rectangular tubes extend along the upper and lower edges of the opening and have slots to receive supporting pins that are pivotally connected to the top and bottom of each panel near one vertical edge so that these edges slide along the channels as the door is folded open.

Mechanism for Supporting Bifold Doors for the Enclosure of a Data Processor

Some enclosures for data processors have a wide vertical opening that is covered by bifold panels. Rectangular tubes extend along the upper and lower edges of the opening and have slots to receive supporting pins that are pivotally connected to the top and bottom of each panel near one vertical edge so that these edges slide along the channels as the door is folded open.

The lower channel supports the panel both vertically and horizontally and the upper channel supports the panel only vertically. Each vertical inside wall of the upper channel supports a track. The tracks are at different heights, and the upper pin carries two rollers that have circumferential grooves that hold each roller on one of the tracks. The lower pin is adapted to carry two rollers on a common horizontal axis. These rollers have circumferential grooves and the inside horizontal surfaces of the lower channel carry correspondingly positioned tracks.

The panel is blow molded plastic, and it supports a metal sleeve that carries the end of the pin. The sleeve is mounted in a way to prevent it from rotating. Inwardly facing tabs on the sleeve snap into a circumferential groove on the pin to hold the pin in a vertical position.

The panel is formed of plastic by blow molding. When the panel is viewed in section, its inner surface is convoluted to provide horizontal supports for the sleeve.
