Definitions

  • Canadian patent 1,040,606 discloses an electrical coupling system which simultaneously provides for electrical contact of the fixture to the outlet box wiring, while securing the light fixture in place.
  • the electrical outlet box is provided with a face plate which presents the electrical contacts in combination with lug portions.
  • the light fixture includes mating lug portions which on rotation clip into and secure the light fixture in place on the face plate.
  • the lug portions on the light fixture also include electrical contacts which lead to the lamp of the fixture. Hence when the lug portions are engaged to support the light fixture, the electrical contacts engage to complete the circuit.
  • the drawback with this system is that, due to the inter-relationship of the lugs and the electrical contacts, there is a limitation on the amount of support that can be provided in the lug systems while continuing to provide suitable engagement of the electrical contacts.
  • the electrical contacts are left exposed thereby presenting potential hazard in mounting the light fixture in place or allowing the user to reach up into the outlet of the face portion and contact one or more of the live electrical leads.
  • FIG. 1 and 2 of the prior art Canadian patent illustrate that a central threaded tubular rod is mounted to the coupling as a central tubular rod connector.
  • the threaded tubular rod is relatively short and is designed to hold the cover plate in position and to provide a thread to attach a ring (or hook) upon which a light fixture or chain is hung.
  • the disclosure describes use of the ring (or hook) in terms which are specific to the application of hanging a light fixture or chain therefrom.
  • each terminal 30, 32 and 34 is surrounded by a raised ridge portion 36, 38 and 40.
  • the raised ridge serves to contain the looped end portion of the respective electrical wire lead and captured in place during connection of the leads to the terminals.
  • the male component 14 has an electrical wire 42 which is connected to a light fixture or the like extending through a decorative dished-shaped exterior plate 44 and through an aperture 46 of the male component 14 and into the chamber generally designated 48.
  • Three electrical wires of the incoming light fixture wire 42 which are shown designated 50, 52 and 54. However, in practice, only two such wires 52 and 53 are used, the ground wire 50 commonly being replaced by an electrical contact between the metal body of the fixture and the cross bar (not shown) of the outlet box.
  • the wires 50, 52 and 54 are respectively secured to the electrical terminals 56, 58 and 60.
  • the terminals 56, 58 and 60 are surrounded by a raised ridge portion 62, 64 and 66. This assists in assembly and connection of the electrical wires to the terminals to capture them in place.
  • Each of the terminals 56, 58 and 60 include outwardly extending contacts 68, 70 and 72. These male contacts engage corresponding female contacts of the female component 12, as will be discussed with respect to Figures 2, 3 and 4.
  • a locking device is incorporated into the female component 12 in the form of small domed protrusions or dimples 79 and 81 which are designed to slide over the surfaces of winged recesses 74 and 76 of male component 14 when the male component 14 is being rotated clockwise relative to female component 12 for connecting the male and female components.
  • the dimples 79 and 81 abut the winged recesses 74 and 76 when the male component is rotated into connection with the female component, thereby effectively preventing inadvertent counter-­clockwise rotation of the male component 14 relative to the female component 12 without the application of a reasonable amount of torque.
  • a ridge 15 which defines an octagonal shape which corresponds to the inner dimensions of a standard octagonal electrical outlet box 16.
  • the raised ridge 15 correctly locates the base plate bolt holes 94 and 96 with the bolt holes 98 and 100 on the lugs 102 and 104 of the electrical box 16. This ensures a secure fitment of the female component 12 to position the component in the electrical outlet box 16.
  • the circular disk, or flange 99, outside the octagon shaped ridge 15 extends beyond the dimensions of the electrical box and thereby ensures that the component 12 fits flush to a wall or ceiling even though the outlet box may be recessed or misaligned.
  • the female component 12 includes a further ridge 17 for providing clearance for the electrical wiring extending between the female component 12 and the ceiling.
  • the raised ridge may provide clearance, (e.g. a few centimeters) for a terminal block for the electrical wiring which comes through the building surface.
  • the overall dimensions of male component 14 and female component 12 can be reduced in such an installation. In practice this means that the circular disk, or flange 99, and the octagonal shaped ridge 15, which extend outwards from the raised ridge 17, of the base plate 12 are no longer necessary and can be eliminated.
  • the underside 106 of the female component 12 ( Figure 2), which constitutes the face plate of the electrical outlet box, includes two sets of semi-­circular ring portions generally designated 108, 110, 112 and 114.
  • Ring set 108 and 110 include a plurality of catches, the entrance to which are defined by the respective recesses 116, 118, 120 and 122.
  • the inner set of rings 112 and 114 include the female resilient clips of electrically conductive metal. The entrance to those clips is defined by recesses 124, 126 and 128. The clips are recessed so as to conceal live electrical parts.
  • the male component 14 includes on an outer ring set 130 and 132 the outwardly projecting stud portions 134, 136, 138 and 140.
  • outwardly extending male contacts 68, 70 and 72 are provided on the inner ring portion, as defined by circular edge 142.
  • the male component is provided with an integrally molded arrow 144 which, when aligned with the indented arrow 146 of the female component, automatically aligns the studs 134, 136, 138 and 140 with the recesses 116, 118, 120 and 122.
  • the electrical contacts 68, 70 and 72 are aligned with the recesses 124, 126 and 128.
  • the male component 14 is rotated in the direction of arrow (clockwise) 148 to engage the studs with the catches.
  • the studs are defined by the lugs 136 and 138 which are of inverted L-shape to define undercut portions 150 and 152.
  • the catches of the female component 12 are defined by the depending ledges 154 and 156 to define supporting surface 158 and 160.
  • the terminals 30 and 32 include resilient clips 162 and 164.
  • clips are J-shaped as protected by face portions 166 and 168 of the respective ring portion 112 and 114.
  • the ledges 166 and 168 in covering the clips 162 and 164 prevent the user from engaging the clips with their fingers or various tools, such as screwdrivers, and hence substantially reduce the risk of electric shock during installation.
  • the J-shaped clips 162 and push connectors 163 are secured to the female component at the raised block portion 170 by way of the terminal screw or rivet 172. Hence a cantilever mounting of the J-shaped clip 162 is provided with a flexible distal portion 174. Multistrand wire may be inserted between clip 162 and push connector 163 which yields under bending pressure. The connector 163 then clamps down on the wire and secures the wire in place with a contact area extending fully around the arcuate portion of connector 163.
  • the push connector arrangement of Figure 4A may also be advantageously used for the terminals 58 and 32.
  • the distal portion 174 is pushed upwardly by the male contact 72 to ensure secure electrical contact between the male and female components.
  • a similar action occurs with respect to the other electrical clips of the female component which occurs at the same time as the stud components of the male couplings 68 and 70 engage the associated catches of the female components (e.g. 162 and 164).
  • the assembled unit as shown in Figure 4, has the studs 134, 136, 138 and 140 engaged with the respective supporting ledges as exemplified in Figure 4 as 154 and 156.
  • the male contacts 70 and 72 engage the respective clips 162 and 164, thereby effecting a hanging cord lamp fixture connection as shown in Figures 10A and B.
  • the electrical cord 42 is secured by means of a cord restrainer 1004.
  • the restrainer effectively transfers the weight of the fixture to the flange 180 surrounding the aperture 46 of male component 14, and thereby to the female component 12 through the male component 14 via the support lugs 134, 136, 138 and 140 engaging the corresponding catches of the female component. No stress is applied to the electrical contacts 70 and 72.
  • the design of the lugs and catches of the male and female components is independent of the electrical contacts to thereby support any desired weight of the light fixture without interfering with the electrical contacts.
  • the electrical contacts resiliently urge the clips upwardly to ensure continued electrical contact of the light fixture to the power source in incoming line 18.
  • the male component 14 has extending outwardly of the stud portions a plate extremity 182, 184 for supporting the two-bolt fixture of Figures 5 and 6 via apertures 74 and 76.
  • the female component 12 is flush against the face of the finishing material for the wall or ceiling to complete the assembly and provide a flush mount of the light fixture, and the cover plate 44 extends so as to cover the entire connector and fit flush with the wall or ceiling.
  • the male and female components of the coupling device are attached by means of the separate inter-­engaging studs and catch portions.
  • the system has been designed for close tolerances to achieve a secure and strong connection between the components. Once locked the components have a very low profile for preventing the female component 12 from intruding into the outlet box, and to ensure that the device remains inconspicuous when the male component 14 is not attached.
  • the components of the device may be injection molded of suitable plastic resin.
  • the plastic resin may include flame retardant, heat resistant, creep resistant additives.
  • a suitable plastic may be that of acrylonitrile butadiene styrene composition.
  • FIG. 5 a combined half-section and exploded view is provided of a bolt mounted fixture according to a first alternative embodiment mounted in the form of a retrofit.
  • An ordinary two-bolt light fixture is mounted on the male component 14 by means of a pair of bolts 500 and 502 inserted through apertures 76 and 74, and secured by means of lock nuts 504 and 506, spacer nuts 508 and 510, and decorative nuts 512 and 514.
  • the height of the cover plate 44 is determined by adjustment of spacer nuts 508 and 510.
  • the bolts 500 and 502 are maintained in a correct width position within slots 74 and 76 by means of lock nuts 504 and 506.
  • the cover plate 44 is secured to the bolts 500 and 502 by means of nuts 512 and 514, respectively.
  • a modified light fixture is illustrated with reference to Figure 6.
  • Manufacture installed mounting lugs 600 and 602 are provided with holes 604 and 606 through which a pair of self-taping screws 608 and 610 may be inserted, via holes 76 and 74 of the male component 14.
  • the mounting lugs are installed at an appropriate height for correct positioning of the male component attachment plate 14 relative to the female component base plate 12.
  • Correct spacing between the male component 14 and the associated bolt mounted light fixture can also be realized by employing either central tubular spacer rings or tubular rod spacer rings as shown in Figures 7 and 8, respectively.
  • a central tube spacer ring 700 is mounted via a friction fit over the raised circular portion 702 of the male component 14.
  • the spacer ring 700 can be constructed to various heights for achieving selective spacing of the cover plate 44 relative to the male component 14.
  • Figure 8 shows a pair of tubular rod spacers 800 which can be manufactured to predetermined heights to achieve selective spacing of the cover plate 44 relative to the male component 14.
  • a pair of bolts 500 and 502 are inserted through the apertures 74, 76 of the component 14 and through the tubular rod spacers 800.
  • a pair of decorative nuts 512 and 514 are fastened to the bolts 500 and 502 which protrude to respective apertures in the cover plate 44.
  • FIG 10A illustrates a hanging cord fixture embodiment of the present invention in which a flexible electrical cord 42 extends from a lamp shade 1002 through an aperture 46 in the male component 14 which is held in place with a cord restrainer 1004 shown in detail with reference to Figure 10B.
  • the cord restrainer 1004 slides along the electrical cord 42 for adjusting the height of the lamp and the length of wiring which extends to the electrical contacts on the male component 14.
  • the cord restrainer 1004 fits into and is compressed by the aperture 46 which restrains movement of the cord.
  • a cover plate 44 is shown in Figure 10A attached via a friction fit over the raised circular portion 702 of the male component 14.
  • Figure 11 shows a hanging chain fixture according to another alternative embodiment of the present invention, wherein chain links 1100 are supported by a hook 1102 having a central threaded aperture for receiving a threaded tubular rod 1104.
  • a pair of lock nuts 1106 connect the tubular rod 1104 to the male component 14.
  • the hook 1102 is threaded onto the tubular rod 1104 for supporting the fixture connected at a remote end of chain 1100 and to hold the cover plate 44 to the building surface.
  • attachment plate or male component 14 may be directly injection molded with a lamp fixture base to produce an integral unit (not shown). In such a case, only the central portion of the male component 14 is utilized. The elongated recesses 74 and 76 would not be used. Also, the electrical cord 46 is substituted with a direct electrical connection from the contacts 68, 70, 72 to the light bulb socket or sockets.
  • FIG 12 an alternative embodiment of the female component 14 is shown with a ground strap 1200 for providing a ground connection between a metal light fixture and the ground terminal 60 ( Figure 1) of the male component 14.
  • the ground strap 1200 is secured by a screw 1202 to a metal threaded insert (not shown) extending from the terminal 60 to the ground strap 1200.
  • the threaded metal insert is screwed on both sides of the male component (e.g. via terminal 60 on one side and via screw 1202 on the other side).
  • a distal end of the ground strap 1200 is secured to male component 14 via a screw or rivet 1204.
  • the ground strap 1200 provides a ground contact for central tubular mounted or like fixtures by securing the strap between the lock nut 902 and 904 in Figure 9 or 1106 in Figure 11.
  • the lock nut 904 would be placed on the central tubular rod 900, then the rod would be inserted through the aperture in the strap 1200 and into the aperture 46 of the male component 14.
  • the nut 1106 would be threaded onto tubular rod 1104 in a similar manner.
  • the lock nut 902 (or 1106) effectively secures the strap 1200 against the male component 14 for providing the necessary electrical connection between the central tubular rod 900 (or 1104) and terminal 60 via the screw 1202 through the ground strap to the terminal.
  • the ground strap 1200 also provides a ground connection for the two point mounted fixture illustrated in Figures 5 and 6.
  • the screw 500 (or 608) is inserted through the aperture 76 of the male component 14 and then through the slotted aperture of the ground strap.
  • the strap 1200 is secured between the lock nut 504 (or lug 600) and the male component thus providing an electrical connection between the screws securing the cover plate 600, and hence between the metallic fixture cover and the ground terminal 60.
