Definitions
- the present invention relates to locking mechanisms and hinges for ceiling light fixtures used as housings for fluorescent lamps in homes, stores, factories and offices.
- Many such locks and hinges are known in the prior art, but none of these has proven completely suitable for its intended purpose.
- most prior art fixtures have complicated lock mechanisms comprising several parts, and they are costly both to manufacture and to maintain in operation.
- On other fixtures tools are required for releasing, closing and adjusting locks, thus lengthening the time required for cleaning and for replacement of bulbs.
- FIG. 3 is an enlarged, fragmentary, longitudinal cross-sectional view taken substantially on the line 3-3 of FIG. 2;
- FIG. 4 is a transverse cross-sectional view of the light fixture, showing its plastic diffuser cover in open position;
- FIG. 5 is a perspective view of a preferred embodiment of the combination locking spring and hinge of the invention.
- the front panel 22 of the cover 20 is complementary to and mates with the diminutive: front wall 14 of the housing 12.
- the front wall 14 terminates at its lower extremity in an upwardly and rearwardly directed hook-shaped tab 24.
- An upper portion of the front panel 22 includes a tab-engaging cover lock 25 which is generally C-shaped in transverse cross-section and includes a horizontal web 26 directed forwardly of the front panel 22.
- the web 26 and tab 24 are adapted to overlie one another in overlapping engagement to form cover locking means for maintaining the cover 20 closed.
- the interior of the housing 12 is provided with a generally L-shaped light reflector 30 which includes a horizontal reflecting panel 31 attached to the top wall 16, and a vertical rear reflecting panel 32 secured to the bottom wall 17.
- Two conventional fluorescent bulbs 33 constitute illuminating means by which the fixture 11 generates light. Lateral ends of the bulbs 33 are plugged into sockets 34 which also comprise means securing the bulbs 33 within the housing 12. Details of the connection between the bulbs 33 and their respective sockets 34 are not shown. Electrical wiring, an electrical switch, and a starter (not shown) are included to make the illuminating means operable, all as well known in the art, and requiring no further desciption.
- FIGS. 2-4 The manner in which a light fixture constructed according to the teachings of the present invention is opened and closed is illustrated in FIGS. 2-4.
- the cover 20 is suspended from the housing 12 by hinge means including a pin means or pin 40 attached to the cover 20, and a'spring band strap 41 secured at its upper end 42 to the top reflecting panel 31.
- hinge means pivotally securing said cover to said housing, whereby said cover is selectably shiftable between a first, locked position in which said cover is horizontally disposed to bridge and close said housing and a second position in which said cover is suspended to hang vertically from said housing to expose the interior of said housing and to permit access thereto, and
- said locking means comprising a horizontal web connected to and directed forwardly of said front panel, and a cooperating rearwardly directed tab extending from said front wall, said web and said tab being adapted to overlie one another in overlapping engagement;
- said spring band strap is biased forwardly resiliently to urge said web of said cover into locking engagement with said tab of said housing, said cover being shiftable rearwardly to overcome the bias of said strap to effect disengagement of said web from said tab, thereby to permit said cover to pivot downwardly to an open position to provide access to the interior of said housing.
- said flange means of said spring band strap comprises a pair of wing tabs connected to and directed forwardly of said strap, said wing tabs each being formed with an aperture adapted supportingly to receive said pin means therethrough.
