A hinging mechanism attaching an access panel to a housing is provided that has a latching device rigidly mounted to the inner surface of the panel and releasably pivotally secured to the interior surface of the housing, whereby the panel is detachable from the housing and free to move between open and closed positions. Preferably, the mechanism further includes a linkage member movably mounted to the interior surface, whereby the mechanism has articulation at independent points between the housing and the panel. The mechanism is also preferably one where the latching device includes a latch-bracket and a latch, the latch being pivotally attached to the latch-bracket.

The invention claimed is: 1. A hinging mechanism attaching an access panel to a housing, the housing having an interior surface and the access panel having an inner surface, the mechanism comprising a latching device rigidly mounted with respect to the inner surface, the latching device having a latch free to pivotally move between secured and released positions, and a linkage member pivotally mounted with respect to the interior surface and having a hinge-bar, the latching device receiving and entirely encompassing the hinge-bar in the secured position to releasably and pivotally secure the hinge-bar, whereby the panel is free to move between open and closed positions, the linkage member being free to pivot in the open position such that the mechanism is free to rotate concurrently about the interior surface and the hinge-bar, and the panel is detachable from the housing. 2. The mechanism of claim 1 wherein the latching device has a latch-bracket, the latch pivotally attached with respect to the latch-bracket, whereby the latching device is detachable from the hinge-bar with movement of the latch from the secured position to the released position. 3. The mechanism of claim 2 wherein the latching device further has a spring member engaged with respect to the latch, the spring member being adapted to bias the latch in the secured position. 4. The mechanism of claim 3 wherein the latch includes rear and front appendages, whereby rotation of the latch is halted upon contact of either appendage with the latch-bracket. 5. The mechanism of claim 3 wherein the latch-bracket includes two latch-supports at opposite ends, each latch-support having a support-notch sized to receive the hinge-bar, the support-notches being substantially aligned. 6. The mechanism of claim 5 wherein the latch-bracket further includes a stabilizer bar extending between the latch-supports and the latch is pivotally attached to the stabilizer bar. 7. The mechanism of claim 5 wherein the latch includes a grip-notch such that the grip-notch restrains the hinge-bar within the support-notches when the latch is in the secured position. 8. The mechanism of claim 7 wherein the latch further includes an inclined front surface adjacent to the grip-notch, the front surface being adapted to slidably engage the hinge-bar to allow the hinge-bar to pivot the latch into the released position, whereby the latching device is able to pivotally secure the hinge-bar. 9. The mechanism of claim 2 wherein two support-mounts are rigidly secured to the interior surface and the linkage member includes two substantially aligned linkage-arms, each of the linkage-arms being pivotally mounted to a separate support-mount and having a distal end, the hinge-bar extending between the distal ends. 10. The mechanism of claim 9 wherein the latch-bracket has a height and each of the linkage-arms has a length, the length being less than the height such that the linkage-arms can nest within the latching device to compactly store the mechanism within the housing when the access panel is in the closed position. 11. The mechanism of claim 1 wherein the housing is an area lighting-fixture housing and the panel is an access door. 12. In an area lighting fixture of the type utilizing power-related components and a high-intensity-discharge lamp and having a housing with an interior surface and an access opening, an access door with an inner surface and sized to cover the opening, and a hinging mechanism attaching the housing to the door for movement of the door between open and closed positions, an improvement wherein the hinging mechanism comprises: a linkage member pivotally mounted with respect to the interior surface and having a hinge-bar, the linkage member being free to pivotally in the open position; and a latching device rigidly mounted with respect to the inner surface, the latching device having a latch free to pivotally move between secured and released positions, the hinge-bar being received by the latching device, the latching device entirely encompassing the hinge-bar in the secured position to releasably and pivotally secure the hinge-bar, whereby the door is detachable from the housing, and the mechanism is free to rotate concurrently about the interior surface and the hinge-bar to provide articulation at independent points between the housing and the door. 13. The lighting fixture of claim 12 wherein the latching device includes: a latch-bracket having two latch-supports at opposite ends, each latch-support having a support-notch sized to receive the hinge-bar; the latch pivotally attached with respect to the latch-bracket; and a spring member engaged with respect to the latch, the spring member being adapted to bias the latch in the secured position. 14. The lighting fixture of claim 13 wherein the interior surface has two support-mounts and the linkage member includes two substantially aligned linkage-arms, each of the linkage-arms being pivotally mounted to a separate support-mount and having a distal end, the hinge-bar extending between the distal ends. 15. The lighting fixture of claim 14 wherein the latch-bracket has a height and each of the linkage-arms has a length, the length being less than the height such that the linkage-arms can nest within the latching device to compactly store the mechanism within the housing when the door is in the closed position. 16. The lighting fixture of claim 15 wherein the latch has a grip-notch and an inclined front surface adjacent to the grip-notch, the front surface being adapted to slidably engage the hinge-bar to allow the hinge-bar to pivot the latch into a released position and the grip-notch being adapted to restrain the hinge-bar within the support-notches when the latch is in the secured position. 17. The lighting fixture of claim 16 wherein the latch further has rear and front appendages such that rotation of the latch is halted upon contact of either appendage with the latch-bracket.
