Abstract

The illustrated housing arrangement (Fig. 1) provides an esthetic cover for electronic circuit components and yet permits immediate accessibility for service, without removing covers. In the closed position, cover 1 of gate (door) 2 must mesh neatly with cover 3 of stationary (main) frame 4 (see Fig. 2). While opening, the cover must move through a tightly controlled path permitting the edge of cover 1 to clear neighboring edge surfaces of cover 3.

Covered Gate With Hidden Hinges and Tight Opening Clearance

The illustrated housing arrangement (Fig. 1) provides an esthetic cover for electronic circuit components and yet permits immediate accessibility for service, without removing covers. In the closed position, cover 1 of gate (door) 2 must mesh neatly with cover 3 of stationary (main) frame 4 (see Fig. 2). While opening, the cover must move through a tightly controlled path permitting the edge of cover 1 to clear neighboring edge surfaces of cover 3.

In order to obtain the necessary movement without exposed hinges, handles, latches or other elements, a dual-linkage hidden hinge arrangement is used. Link member 6 and hinge 8 a-c support gate 2 and establish its path of movement relative to frame 4. In the closed position (Fig. 3) hinge member 8c and link member 6 nest compactly. When opening, the edge of cover 1 nearest cover 3 moves through a tightly restricted arcuate path, clearing the cover 3 without touching.
