Vandal resistant lighting fixture and method of manufacture thereof

1. A vandal resistant lighting fixture, comprising:

a base having a first side wall and a flange extending from the first side wall, the flange defining a first opening;

a cover having second sidewall and a cap extending from the second sidewall, the second sidewall having interior and exterior peripheries, the cap having second opening through which light from an illumination source may pass;

a securing mechanism configured to rotatably secure the cover to the base when the cover is rotated in a first direction relative to the base to a secured position; and

a magnetically operable latching mechanism having latched and unlatched settings, wherein when the cover is in the secured position, the latching mechanism prevents rotation of the cover relative to the base in a second direction opposite the first direction when the latching mechanism is in the latched position.

2. The lighting fixture of claim 1 , wherein the magnetically operable latching mechanism further comprises a bracket attached to the base; and

a biasing member pivotally attached to the bracket so as to rotate about a pivot axis and into latched and unlatched positions respectively corresponding with latched and unlatched positions of the magnetically operable latching mechanism.

3. The lighting fixture of claim 2 , wherein the biasing member comprises proximal and distal ends and an engagement tab situated proximate to the distal end and configured to be biased against the inner periphery of the second sidewall.

4. The lighting fixture of claim 2 , further comprising at least one stop tab situated at the inner periphery of the second sidewall.

5. The lighting fixture of claim 4 , wherein the at least one stop tab is configured to engage a portion of the biasing member when the biasing member is in the latched position.

6. The lighting fixture of claim 2 , wherein the biasing member comprises a coupling portion configured to magnetically couple to a magnetic key to receive a force from the magnetic key to rotate the biasing member about the pivot axis to toggle the latching mechanism between the latched and unlatched positions.

7. The lighting fixture of claim 2 , wherein the bracket comprises a Z-shaped bracket having first and second folds, the second fold situated at the first opening of the flange.

8. The lighting fixture of claim 1 , wherein when the cover is in the secured position, the latching mechanism allows rotation of the cover relative to the base in the second direction opposite the first direction when the latching mechanism is in the unlatched position.

9. A method for forming a vandal resistant lighting fixture, the method comprising acts of:

forming a base having a first side wall and a flange extending from the first side wall;

forming a cover having a second side wall and a cap, the second sidewall having opposed inner and outer peripheries;

forming an opening in the cap through which light from an illumination source may pass;

configuring a securing mechanism to rotatably secure the cover to the base when the cover is rotated in a first direction relative to the base to a secured position; and

forming a magnetically operable latching mechanism having latched and unlatched settings, wherein when the cover is in the secured position, the latching mechanism prevents rotation of the cover relative to the base in a second direction opposite the first direction when the latching mechanism is in the latched setting.

10. The method of claim 9 , wherein the act of forming the magnetically operable latching mechanism further comprises acts of:

attaching a bracket; and

pivotally attaching a biasing member having proximal and distal ends to the bracket such that the biasing member rotates about a pivot axis and has latched and unlatched positions respectively corresponding with latched and unlatched settings of the latching mechanism.

11. The method of claim 10 , further comprising acts of:

forming an engagement tab at a proximal end of the biasing member; and

situating the engagement tab such that the engagement tab is biased against the inner periphery of the other sidewall of the cover.

12. The method of claim 10 , further comprising an act of forming one or more stop tabs at the inner periphery of the other sidewall of the cover.

13. The method of claim 12 , wherein the one or more stop tabs are configured to engage the engagement tab when the biasing member is in the latched position and bypass the engagement tab when the biasing member is in the unlatched position.

14. The method of claim 10 , further comprising an act of forming the biasing member from a ferromagnetic material configured to couple to a magnetic key to receive a force from the magnetic key to toggle the biasing member between the latched and unlatched positions respectively.

15. The method of claim 10 , further comprising acts of:

folding the bracket twice in opposite directions between proximal and distal ends of the bracket so as to form a “Z” shaped bracket; and

situating a portion of the bracket at the opening of the flange.

16. The method of claim 10 , further comprising an act of configuring the biasing member such that when the cover is in the secured position, the biasing member allows rotation of the cover relative to the base in the second direction opposite the first direction when the biasing member is in the unlatched position.

17. A vandal resistant lighting fixture, comprising:

a base having a first side wall and a first flange extending from the first sidewall, the first sidewall having an outer periphery;

a cover having a second sidewall and a cap extending from the second sidewall, the second sidewall having inner and outer peripheries, the inner periphery of the second sidewall configured to extend about the outer periphery of the first sidewall of the base;

an opening situated in the cover through which light from an illumination source may pass;

a securing mechanism configured to rotatably secure the cover to the base when the cover is rotated in a first direction relative to the base to a secured position; and

a magnetically operable latching mechanism comprising a biasing member having latched and unlatched positions, wherein when the cover is in the secured position, the latching mechanism prevents rotation of the cover relative to the base in a second direction opposite the first direction when the biasing member is in the latched position.

18. The lighting fixture of claim 17 , wherein the magnetically operable latching mechanism further comprises a bracket attached to the base; and

wherein the biasing member is pivotally attached to the bracket so as to rotate about a pivot axis and into latched and unlatched positions respectively corresponding with latched and unlatched positions of the magnetically operable latching mechanism; and wherein the biasing member comprises a magnetic coupling portion configured to magnetically couple to a magnetic key to receive a force from the magnetic key to rotate the biasing member about the pivot axis and to the latched or unlatched positions of the biasing member.

19. The lighting fixture of claim 17 , further comprising a magnetic key configured to magnetically couple to the biasing member when the magnetic key is situated at the outer periphery of the second sidewall of the cover.

20. The lighting fixture of claim 18 , wherein the biasing member further comprises a spring situated between a second flange attached to the base and the inner periphery of the second sidewall of the cover.
