As used herein, the terms “substantial” and “substantially” means, when comparing various parts to one another, that the parts being compared are equal to or are so close enough in dimension that one skill in the art would consider the same. Substantial and substantially, as used herein, are not limited to a single dimension and specifically include a range of values for those parts being compared. The range of values, both above and below (e.g., “+/−” or greater/lesser or larger/smaller), includes a variance that one skilled in the art would know to be a reasonable tolerance for the parts mentioned.
The above discussion is meant to be illustrative of the principles and various embodiments of the present invention. Numerous variations and modifications will become apparent to those skilled in the art once the above disclosure is fully appreciated. It is intended that the following claims be interpreted to embrace all such variations and modifications.
Headings are provided for the convenience of the reader, and are not intended to be limiting in any way.
The disclosure herein relates to the inventor's prior work, such as that set forth above in the documents identified in the Related Patents and Applications section, the contents of each of which are herein incorporated in their entirety by reference.
This disclosure relates to providing additional safety for electrical fixtures supported/suspended by electrical wires, and sets forth improvements related to various embodiments of the plug and socket combinations in related patents and applications of the inventor which include a suspension cable carrying electricity. Lighting fixtures that include or are retrofitted to provide plug and socket combinations with a wire cover are additionally disclosed herein.
As described in additional detail in the incorporated references, the plug and/or socket can include a sensing unit for at least one of wirelessly communicating a sensed condition and wirelessly receiving a signal, particularly as disclosed in PCT International Patent Application No. PCT/US2016/032170 filed May 12, 2016 and PCT International Patent Application No. PCT/US2018/020987 filed Mar. 5, 2018.
A “quick connect device” for installing electrical fixtures comprises the combination of a plug and mating socket, which is also known as a receptacle. This combination is described in great detail in the incorporated references, and is summarized herein for the convenience of the reader. The plug and mating socket of the device function to both establish an electrical connection between an electrical fixture and electrical supply wiring, and mechanically support the fixture on a surface or base, typically a wall, ceiling or floor surface.
As used herein, the term “fixture” or “electrical fixture” means any fixture or appliance such as a lighting fixture, ceiling fan, television camera, security device or any other device which is powered by electricity supplied by electrical wiring, and which requires a mechanical connection to support or suspend the fixture.
The plug is fixedly secured to an electrical fixture, while the socket is secured to either the surface (e.g., wall, ceiling or floor) on which the fixture is to be mounted, or to an electrical junction box. The structure, function, and operation of the plug and mating socket, generally, have already been detailed in, for example, the patents and application incorporated by reference herein.
With reference to
The basic functionality of socket 400 and plug 500 are known, as disclosed in the incorporated references, and as codified in the U.S. National Electric Code. By way of review; as can be seen in
Plug 500 includes a body 524 supporting a plurality of concentric conductive rings 526 each connected by an internal conductor 534 to a terminal 536 (
Alignment spline 538 can be disposed about a peripheral portion of body 524, positioned to mate with alignment spline 438 of socket 400, to prevent radial rotation of plug 500 relative to socket 400 after plug 500 and socket 400 are connected.
A spindle 564 having a hollow spindle bore 566 is connected to body 524 to extend axially away from a center of body 524. A pin 568 having at least one narrowed pin diameter portion 570 is slidable within spindle bore 566. Spindle 564 includes one or more radial channels 572. Pin 568 can be slid within bore 566 to position narrowed pin diameter portion 570 adjacent a radial channel, in an unlatched position of pin 568. One or more retaining balls 574 are each positioned within a radial channel.
Spindle 564 is inserted within socket bore 450 when connecting socket 400 and plug 500, when pin 568 is in the unlatched position. In this position, narrowed bore diameter portion 452 of socket 400 can urge retaining balls 574 within the narrowed bore diameter portion 452 radially inwards towards a central axis of spindle bore 566, whereby a portion of each retaining ball 574 lies within channel 572, and a portion lies within the narrowed pin diameter portion 570). When spindle 564 is fully inserted within socket bore 450, radial channels 572 are positioned outside of narrowed bore diameter portion 452 within the larger diameter of socket bore 450. As such, pin 568 can be slid within spindle bore 566 to position narrowed bore diameter portion 452 away from and out of alignment with any of radial channels 572, to a latched position. In the latched position, each of retaining balls 574 is forced radially outwards by the wider general diameter of pin 568 to be positioned partly within radial channel 572 and to extend partly outside of radial channel 572 to lie partly within the larger diameter of socket bore 450. As such, a diameter defined by a retaining ball extending in this manner together with the diameter of spindle 564 is greater than the diameter of narrowed bore diameter portion 452, and spindle is thus unable to pass through narrowed bore diameter portion 452 and cannot be withdrawn from socket 400.
In an embodiment shown in
As described above, pin 568 is moved axially within spindle bore 566 to move between latched and unlatched positions. In another embodiment,
Further, pin 568 is provided with a cam follower 610 which slidingly mates with lever cam surface 606. Mating engagement of lever cam surface 606 and pin cam follower 610 enables pin 568 to move into the latched position, urged by a cam spring 612 which is positioned between a surface of spindle 564 (as shown) or body 524 and a surface of pin 568 or a surface attached to pin 568 (as shown). A lever spring 614 extending between body 524 and release lever 602 urges lever 602 into this mating position to further encourage locking of plug 500 to socket 400.
An end effector 608/608A/608B is disposed at an end of lever 602 and is pushed or pulled to move lever cam surface out of mating engagement with pin cam surface 606, and to drive pin 568 into an unlatched position. End effectors 608, 608B are substantially aligned with an axis of movement of release lever 602, while end effector 608A includes a portion that is substantially offset from this axis. An offset can be selected which positions end effector 608 in a convenient location for use. Guide channel 616 and guide pin 618 can be provided to cooperatively define a limit of movement of lever 602, as well as to guide movement of lever 602. An end effector connector 624 can be provided into which an end effector 608 can be inserted or otherwise attached. Additional detail is provided in incorporated reference WO 2020/172390A1.
A lever actuator button 702 can be positioned upon canopy 700 to be aligned with end effector 608, and can be pressed to contact end effector to thereby push release lever 602 to move pin 568 to the unlatched position.
With reference to
In an embodiment, a fixture wiring terminal 502 is provided upon circuit 802, and power or signal wires from a light generating element, such as a lighting fixture, or wires from another type of quick connect enabled device, can be electrically connected to circuit 802. A wiring passthrough 592 can be provided upon bottom enclosure 586 for support and alignment of wires. A terminal wire cover 590 can be provided to prevent accidental access to circuit 802 and to further secure wires connected to wiring terminal 502.
A fixture wire passthrough 954 enables a wire or cable of wires to pass through finial mounting nut 952 or other fixture attachment hardware. Such wire or cable can include a lamp wire, and or other wires which can be interconnected between circuit 802 and a light or other object attached to canopy 700A and housing 594. Alternatively, a wire or cable passing through wire passthrough 954 can connect via a ring 526 and terminal 536 to one or more signals provided by socket 400. In an embodiment, such a wire or cable can pass to circuit 802 first, and from circuit 802 to a ring 526. As such, circuit 802 can change a signal between a connection via a ring 526 and the attached electrical fixture.
In an embodiment, a battery 812 is provided for continuing operation when power supplied from the edifice by wire or induction charging is not operational. Alternatively, battery 812 can independently provide the power needed for operation of device 100, and an access hatch (not shown) can be provided for replacement of battery 812.
Bottom enclosure 586 can include a release aperture 588 through which a release lever end effector or segment 618 can pass, to engage a side push release lever 602 of a side push release mechanism. In the embodiment shown, release lever 602 includes a lever button end 702A contactable by a finger on an exterior of device 100, and an opposed lever end 620 which can be threaded or press-fit or otherwise inserted into or attached to release arm mounting connector 624 of the side push release mechanism. A side push spring 614 biases push release arm 602 into a locked or engaged position, retaining device 100 into mating engagement with a socket portion of a quick disconnect. A side release mechanism is further described in more detail, for example, in incorporated reference WO 2020/172390A1.
In an embodiment, a canopy 700A covers the housing 594 formed by top and bottom enclosures 598, 586. In this manner, various types and styles of lighting (or other) fixtures can be fastened to the enclosure and unique attributes and styles can be configured with the features associated with the elements within housing 594 described herein, without a requirement of providing a housing 594 configuration for all of the various types and styles.
Canopy 700A can include a hanging fixture loop 932, which passes through an aperture in canopy 700A and threads into a spindle extension 904 attached to spindle 564. Spindle extension 904 can be hollow to admit passage of a wire or cable as described herein, and can include an extension opening or slot 908 which permits the wire or cable to emerge inside housing 594. A finial mounting nut 952 adjustably secures canopy 4 to hanging fixture loop 932 and housing 594.
In the embodiment shown, a WiFi antenna 826 is mounted to canopy 700A, connected by wires (not shown) to, for example, circuit 802. A WiFi mounting aperture 723 can be provided for attaching the WiFi antenna 826. Other devices as described in the '469 Publication and other incorporated references can be provided upon canopy 700A and connected to circuit 802 in addition to or instead of WiFi antenna 826. A release actuating aperture 725 is provided so that lever button end 702A can be accessed, or through which end effector 608 or end effector segment 618 can pass.
Canopy 700A can be provided with a canopy lens 727 through which light from LED ring 832 may pass, positioned adjacent to light apertures 729. Alternatively, in place of canopy lens 727, there may be formed a continuous gap or discrete openings (not shown) in canopy 700A through which light from LEDs 834 can emerge. In the embodiment shown, light apertures 729 and canopy lens 727 peripherally surround housing 594 and canopy 24, respectively. In this manner, light emitted by LED ring 832 is emitted circumferentially about canopy 700A after passing through lens 727, which can also be configured as a diffuser, which more evenly distributes light from discrete LEDs 834 to produce a seamless light ring effect when viewed. For example, lens 727 can have a frosted attribute or other light diffusing attribute or finish. Alternatively, lens 727 can extend along a portion of canopy 700A, and can optionally including diffusing properties, to produce shaped light region, which can include symbolic shapes such as letters, tokens, or other symbols.
LED ring 832 can have a ring shape, as shown, or other shape corresponding to lens 727 or other opening in canopy 700A, whereby a substrate holds a plurality of spaced apart LEDs 834. Alternatively, LEDs may be mounted directly to and peripherally about circuit 802. Still further LEDs can be spaced apart on a linear strip that is bent to form a circular or other shape. Likewise, if canopy 700A is not circular. LEDs can be positioned with respect to housing 594 and canopy 700A to shine light along a periphery of any shape, by being either mounted directly to circuit 802 mounted to bottom or top enclosure 586, 598, or mounted to a shaped strip or shaped loop. Similarly, canopy lens 727 can follow a desired peripheral shape, and can act as a diffuser or pass light therethrough unchanged. Alternatively, canopy lens 727 can have a non-clear tint or film, whereby light hues are shifted by canopy lens 27, or whereby an undesired portions of a light spectrum are attenuated or filtered, or desirable portions are emphasized.
Using housing 594 together with a separate canopy 700A provides for a universal inner fixture and a selectable external shape or style. In an alternative, canopy 700A forms and replaces bottom enclosure 586, serving as either part of, together with top enclosure 598, or all of an inner housing while providing an external finish.
While LEDs currently are optimal lighting elements, as they are energy efficient, and can be configured to emit a wide array of colors electronically, it should be understood that other light forms can be used which exist as of this writing, including incandescent, fluorescent, halogen and others, and that in the future other light sources may be used as substitutes for LEDs. and that the disclosure is not limited to LED light sources. Likewise, while LEDs are currently provided as discrete lighting elements, and where a plurality of LEDs can be perceived as a linear light source. LEDs and other light sources exist and may become available which have the form of a continuous linear light source, and which may additionally be flexible.
Accordingly, the disclosure provides an alternate or auxiliary light source which has the form of a peripheral band surrounding a lighting fixture (or other type of fixture) base, and which can be seen from any viewpoint of the fixture. The light emitted by LED ring 832 can serve a plurality of purposes. For example, the band can emit a white or bright color to partially illuminate a room or area, for example to form a ‘night light’ or guide light, without a need to completely illuminate the area, reducing cost and avoiding emitting a possibly disturbing amount of light. The light emitted can be of the same color with a changeable intensity as well as or instead of a changeable color. The intensity and color can be changed by a switch or other user control, or can be changed by electronic circuit 802 in response to a user signal or another signal, for example an electrical signal generated by a sensor, for example a motion sensor or sensor responsive to a change in an environment of the device 100.
Another purpose for the light emitted from LED ring 832 is to signal a state or condition of any one or more of the following: device 100, the area in which device 100 is installed, the edifice, one or more designated individuals, a locale, or a wide geographic area. Examples include a status of one or more sensors within device 100, including an operational state of a microphone or camera, alarm, or motion sensor, or an operational state of device 100 generally. Various colors are indicated in
As noted, the state of a person in the area of the device 100 can be indicated, for example as determined by sensors within device 100. For example, sensors can detect a loud event, such as a fall or cry for help, and illuminate red or other alert color. Other devices in an area can also be illuminated red, whereby support staff observes the color and render aid. Sensors can also detect an unhealthy quality in the air and indicate a warning via a designated color. Likewise, an intrusion can be indicated by a warning color, optionally an alarm sound, and optionally flashing of the warning color. A speed of the flashing can indicate relative alarm or hazard severity, as can the shade or brightness of the light. Other sensed conditions which can be indicated by LED ring 832 as described include an elevated or depressed heart rate, spoken commands, excessive occupancy, or any other condition which can be electronically sensed in the area of device 100, or in the area of other device 100 which is in electronic communication with the device indicating the state or condition. The state or condition can be communicated via one or more connections to terminals 536, or by a wireless signal which can be communicated along the Internet.
Light intensity or color emitted by LED ring 832 can additionally illuminate an appropriate walking path, as indicated by a plurality of devices 100, including a path to safety and an exit. The entire path can be illuminated, or successive devices 100 can illuminate indicating the next portion of the path. Device 100 can include a motion sensor, whereby LED ring 832 emits light only when motion is detected, and for a predetermined period of time thereafter. In this manner, successive devices 100 can illuminate an elongate path or large area only as needed based upon motion.
