~2~ i8 DESCRIPTION OF THE PREFERRED EMBODIMENTS
Various aspects of the present invention will evolve from the following detailed description of the preferred embodiments thereof which should be taken in conjunction with the hereinabove described drawings.
The invention as a whole is represented in the drawings by reference character 10. The recessed lighting unit 10 includes as one of its elements a housing 12, FIGS. 1-5. Housing 12 may be formed into the rectangular solid configuration shown in the drawings using progressive dye manufacturing techniques.
Housing 12 may be constructed of metal or any other material which meets the particular standards set by the el~ctrical authority. With reference to FIGS. 2 and 3, it may be seen that housing 12 encloses an elec-trical lamp 14 and socket 16 therefor. Means 18 mounts electrical lamp 14 and socket 16 to housing 12. Means 18 includes a pair of brackets 20 and 22, FIG. 5, which enclose torsion springs 24 and 26, respectively.
Torsion springs 25 and 26 are held to base 28 by the use of fastening clips 30 and 32, FIGS. 3 and 5. A
yoke 34 aids in the support of the socket 16 and lamp 14. A lens 36 removably fixes to base 28 and generally coincides with opening 38 and housing 12 which is in-tended to allow the passage of light emanating from lamp 14 to the area below which is to be illuminated.
As shown in the drawings, housing 12 is recessed in relation to partition 40 which may be a ceiling, wall, and the like. Housing 12 also includes a locking ; &
seam 42 on the top portion 44 thereof.
Housing 12 structurally connects to junction box 46 via arms 48 and 50. Junction box 46 may include provision for cable 52 which provides electrical power from a source of power shown by the indicia on FIG. 1.
The wires bringing power from the source are spliced in the conventional manner in junction box 46 and carried to housing 12 and lamp and socket 14 and 16 therein via wires 54 and 56. Junction box 46 may also have a plurality of knockout covers 58 and a pair of side covers 60 and 62, FIGS. 1, 2 and 4.
Unit 10 also includes as one of its elements thermo-protector means 64 for detec~ing heat in the vicinity of housing 12 and interrupting electrical power from the power source falling through wires 54 and 56.
Thermoprotector means 64 would perform its function at a selected temperature produced by heat radiating from lamp 14 within housing 12. Thermoprotector 64 may take the form of a bimetal strip such as -the Model No~ M-13D manufactured by Portage Electric of Akron, Ohio. Means 66 mounts thermoprotector means 64 adjacent to housing 12. As may be seen from FIGS.
1, 2, and 5, housing 12 is provided with slot 68 on one side thereof. A container or wireway 70 guides wires 54 and 56 from junction box 46 to the interior of housing 12. Wireway 70 also encloses thermo-protector means 64 and positions the same adjacent housing 12 by the use of protrusions 72 and 74, FIG.
5. Thus, thermoprotector means 64 is always positioned in the same place in relation to housiny 12 which is of great importance to reproduce shut-off results in unit 10. Wireway 70 also includes an element 76 which slidingly engages housing 12 in the vicinity of slot 68. Side portions 78 of wireway 70 and tab 80 of element 76 sandwich the edges 82 and 84 of housing 12 surrounding slot 68. It should be noted that tab 80 may extend beyond the end of slot 86 toward lamp 14. Thus, wireway 70 may be moved away from lamp 16 a certain distance such that tab 8G covers slot 68, FIG. 2. Wireway 70 also includes means 88 for connecting wireway 70 to junction box 46. Such means includes the provision of an extension 90 which may b~ fastened to plate 92 using fastening means 94~ FIG. 5. Flange 96 overlaps the end of junction box 46 to enclose wires 54 and 56 at the conflux of junction box and wireway 704 Extension 90 may be used to provide a place of attachment 98 for a ground wire (not shown), if desired. It may be apparent that the slidiny engagement of element 76 of wireway 70 in combination with means 88 for con-necting wireway 70 to junction box 46 provides a s-truc-tural unit in combination with arms 48 and 50. The slidiny engagement of tab 80 with the side por-tion of housing 12 allows for size tolerances in wireway 70 as well as for thermal contraction and expansion of the elements of unit 10. Element 76 and 80 thereof may also be resiliently attached -to wireway 70 to provide a flexible or springy connection between wireway 70 and housing 12. Tab 80 also conducts heat from interior of housing 12 for detection by therrnoprotector means 64.
Housing 12 also embraces the structure of door 100 which is similarly constructed in re7ation to door 102. Therefore, the following description of door 100 would equally apply to the construction of door 102. Door 100 includes a member 104 in the form of a plate in the embodiment shown on FIG. 5. Member 104 hinyedly attaches to housing 12 at end portion 106.
This may be accomplished by providing end portion 106 with a pair of ears 108 and 110 which fit in a pair of openings 112 and 114, respectively, FIG. 2. The other end 116 of member 104 includes means 118 for latching door 100 to housing 12. Means 118 may include providing housing 12 with an opening 120 there-through. A spring element 122 is fastened to door 100 and projects therefrom. Spring element 122 may include a vent or looped portion 124 which is capable of occupyiny opening 120 of housing 12. It may be apparent that door 100 may be opened by applying pressure to spring element 122 from the outside of housing 12. This may be especially useful after unit 10 has been placed in ceiling 40 to gain access to the area surrounding housing 12, FIG. 5. Doors 100 or 102 may be temporarily brought to the inside of housing 12 while work is being performed on junction box 46.
In addition, unit 10 may also provide for a a hanger mechanism 126 which may be employed in relation to a pair of beams 128 and 130. Hanger mechanism 126 may include a pair of elongated members 132 and 134 and a pair of elongated members 136 and 138. The following description will focus on the functioning of elongated members 132 and 134 of hanger mechanism 126 and may be deemed to be applicable to the functioning of elongated members 136 and 138, which are similarly constructed.
Turning to FIG~ 1, it may be seen that elongated members 132 and 134 are used in conjunction with means 140 for supporting the pair of elongated members to housing 12. Cleats 142, 144, 146 and 1~8 serve to confine elongated members 132 and 134 in sliding engagement with one another adjacent housing 12. As shown in FIG~ 1, member 132 extends to beam 128 while elongated member 134 extends to beam 130.
Each elongated member is identically constructed, using elongated member 132 as an exemplar, to include a shaft 150 in the form of a bar having two portions angularly attached to one another (most clearly shown on FIG. 4 in relation to elongated mem-bers 134 and 138). By this construction, the pairs of elongated members slide in relation to one another and are guided in this movement, FIG. 3. The end portion of elongated member 132 includes an end piece 152 fixed at an angle to shaft 150. Moreover, a lip 154 fixes at an angle to end piece 152, FIGS. 1 and 6. Elongated members, such as elongated member 132, also includes means 156 for fastening the same to ~eams 128 and 130. ~eans 156 may be formed such that end piece 152 is a split member having a first and second portion 158 and 160. First portion may be ber.t into a first and second section 162 and 164. First section 162 of first portion 158 may include an end portion 166, FIG. 1, which is capable of penetrating any of the beams 128 and 130. End piece may include an opening 168 for guiding a fastener, such as nail 170 into beam 128.
In operation, unit 10 might be assembled by placing wires 54 and 56 through wireway 70 in connecting socket 16 at one end thereof. Wireway 70 is then con-nected to housing 12 by the use of means 66 and in the embodiment shown in the drawings, element 76 slidingly engaging the sides of slot 68 of housing 12. The other end of wireway 70 would be affixed to junction box 46 by the use of fastener 94 which would connect extension 90 and plate 92 in adjacent configuration. Unit 10 may then be placed between beams 128 and 130 using hanger mechanism 126 such that the lip 154 of end piece 152 of elongated member 134, 136 and 138, fit under beams 128 and 1300 This accurately positions unit 10 as a recessed lighting fixture. Power can then be brought to junction box 45 via cable 52 and splice to wires 54 and 56 in the conventional manner. Side covers 60 and 62 may then be employed to enclose junction box 46.
Likewise, doors 100 and 102 may be used to close housing 12 leaving opening 38 as the only opening of housing 12.
Socket 16 may then be fastened to housiny 12 using means 18, which includes the provision of placing torsion sprin~s 24 and 26 in the mounting brackets 20 and 22 after fas-tening the same to base 28 by the employment of fastening clips 30 and 32. Yoke 34 may also be employed by fastening the same to base 28. Lamp 14 may then be placed in socket 16 and lens 36 fastened to base 28 to complete the mounting of unit 10. Removal of lens 36 permits the changing of lamp 1~ as desired. Doors 100 and 102 may be opened to gain access to the space immediately adjacent an outside of housing 12 inclu-ding junction box 46.
While in the foregoing embodiments of the present invention have been set forth in considerable detail fGr the purposes of making a complete disclosure of the invention, it will be apparent to those of ordinary skill in the art that numerous changes may be made in such details without departing from the spirit and principles of the invention.
For a better understandlng of the invention, reference is made to the following detailed description which should be referenced to the hereinabove described drawings.
~2~ i8 DESCRIPTION OF THE PREFERRED EMBODIMENTS
Various aspects of the present invention will evolve from the following detailed description of the preferred embodiments thereof which should be taken in conjunction with the hereinabove described drawings.
The invention as a whole is represented in the drawings by reference character 10. The recessed lighting unit 10 includes as one of its elements a housing 12, FIGS. 1-5. Housing 12 may be formed into the rectangular solid configuration shown in the drawings using progressive dye manufacturing techniques.
Housing 12 may be constructed of metal or any other material which meets the particular standards set by the el~ctrical authority. With reference to FIGS. 2 and 3, it may be seen that housing 12 encloses an elec-trical lamp 14 and socket 16 therefor. Means 18 mounts electrical lamp 14 and socket 16 to housing 12. Means 18 includes a pair of brackets 20 and 22, FIG. 5, which enclose torsion springs 24 and 26, respectively.
Torsion springs 25 and 26 are held to base 28 by the use of fastening clips 30 and 32, FIGS. 3 and 5. A
yoke 34 aids in the support of the socket 16 and lamp 14. A lens 36 removably fixes to base 28 and generally coincides with opening 38 and housing 12 which is in-tended to allow the passage of light emanating from lamp 14 to the area below which is to be illuminated.
As shown in the drawings, housing 12 is recessed in relation to partition 40 which may be a ceiling, wall, and the like. Housing 12 also includes a locking ; &
seam 42 on the top portion 44 thereof.
Housing 12 structurally connects to junction box 46 via arms 48 and 50. Junction box 46 may include provision for cable 52 which provides electrical power from a source of power shown by the indicia on FIG. 1.
The wires bringing power from the source are spliced in the conventional manner in junction box 46 and carried to housing 12 and lamp and socket 14 and 16 therein via wires 54 and 56. Junction box 46 may also have a plurality of knockout covers 58 and a pair of side covers 60 and 62, FIGS. 1, 2 and 4.
Unit 10 also includes as one of its elements thermo-protector means 64 for detec~ing heat in the vicinity of housing 12 and interrupting electrical power from the power source falling through wires 54 and 56.
Thermoprotector means 64 would perform its function at a selected temperature produced by heat radiating from lamp 14 within housing 12. Thermoprotector 64 may take the form of a bimetal strip such as -the Model No~ M-13D manufactured by Portage Electric of Akron, Ohio. Means 66 mounts thermoprotector means 64 adjacent to housing 12. As may be seen from FIGS.
1, 2, and 5, housing 12 is provided with slot 68 on one side thereof. A container or wireway 70 guides wires 54 and 56 from junction box 46 to the interior of housing 12. Wireway 70 also encloses thermo-protector means 64 and positions the same adjacent housing 12 by the use of protrusions 72 and 74, FIG.
5. Thus, thermoprotector means 64 is always positioned in the same place in relation to housiny 12 which is of great importance to reproduce shut-off results in unit 10. Wireway 70 also includes an element 76 which slidingly engages housing 12 in the vicinity of slot 68. Side portions 78 of wireway 70 and tab 80 of element 76 sandwich the edges 82 and 84 of housing 12 surrounding slot 68. It should be noted that tab 80 may extend beyond the end of slot 86 toward lamp 14. Thus, wireway 70 may be moved away from lamp 16 a certain distance such that tab 8G covers slot 68, FIG. 2. Wireway 70 also includes means 88 for connecting wireway 70 to junction box 46. Such means includes the provision of an extension 90 which may b~ fastened to plate 92 using fastening means 94~ FIG. 5. Flange 96 overlaps the end of junction box 46 to enclose wires 54 and 56 at the conflux of junction box and wireway 704 Extension 90 may be used to provide a place of attachment 98 for a ground wire (not shown), if desired. It may be apparent that the slidiny engagement of element 76 of wireway 70 in combination with means 88 for con-necting wireway 70 to junction box 46 provides a s-truc-tural unit in combination with arms 48 and 50. The slidiny engagement of tab 80 with the side por-tion of housing 12 allows for size tolerances in wireway 70 as well as for thermal contraction and expansion of the elements of unit 10.

Tab 80 also conducts heat from interior of housing 12 for detection by therrnoprotector means 64.
Housing 12 also embraces the structure of door 100 which is similarly constructed in re7ation to door 102. Therefore, the following description of door 100 would equally apply to the construction of door 102. Door 100 includes a member 104 in the form of a plate in the embodiment shown on FIG. 5. Member 104 hinyedly attaches to housing 12 at end portion 106.
This may be accomplished by providing end portion 106 with a pair of ears 108 and 110 which fit in a pair of openings 112 and 114, respectively, FIG. 2. The other end 116 of member 104 includes means 118 for latching door 100 to housing 12. Means 118 may include providing housing 12 with an opening 120 there-through. A spring element 122 is fastened to door 100 and projects therefrom. Spring element 122 may include a vent or looped portion 124 which is capable of occupyiny opening 120 of housing 12. It may be apparent that door 100 may be opened by applying pressure to spring element 122 from the outside of housing 12. This may be especially useful after unit 10 has been placed in ceiling 40 to gain access to the area surrounding housing 12, FIG. 5. Doors 100 or 102 may be temporarily brought to the inside of housing 12 while work is being performed on junction box 46.

Hanger mechanism 126 may include a pair of elongated members 132 and 134 and a pair of elongated members 136 and 138. The following description will focus on the functioning of elongated members 132 and 134 of hanger mechanism 126 and may be deemed to be applicable to the functioning of elongated members 136 and 138, which are similarly constructed.
Turning to FIG~ 1, it may be seen that elongated members 132 and 134 are used in conjunction with means 140 for supporting the pair of elongated members to housing 12. Cleats 142, 144, 146 and 1~8 serve to confine elongated members 132 and 134 in sliding engagement with one another adjacent housing 12. As shown in FIG~ 1, member 132 extends to beam 128 while elongated member 134 extends to beam 130.
