Background
Recessed lighting systems are typically mounted into an opening in a ceiling or wall. Modern recessed lighting systems generally consist of a bezel, a light source module, driver circuitry, a junction box and a set of hanger bars. The driver is insulated from other parts and components of the recessed lighting system containing the light source module by using the insulation provided by the junction box when the light source module is received therein. The driver is electrically coupled to the light source module using wires or other conduits so that the driver can power the light source module to emit light.
The junction box, the tank, and other components of the recessed lighting system are attached to a hanger bar so that the hanger bar can support the components of the recessed lighting system in a wall or ceiling of a structure. For example, the junction box may be attached to the hanger bar by using screws and bolts that anchor the junction box and the driver.
The commonly owned U.S. patent publication 2015/0233506 invention significantly advances the state of the art or recessed lighting systems having such components. However, there is still an opportunity for further improvement.
Disclosure of Invention
The present inventors have recognized and appreciated that a hanger bar assembly directly coupled to a lighting system housing, such as a junction box, a tank housing, a bracket, or a light fixture frame, provides several benefits to the installation of a lighting system, such as allowing the housing to be positioned in a preferred location between adjacent support structures, such as joists or cross beams. The direct coupling of the hanger bar assembly to the lighting system housing substantially reduces the increased volume and size of conventional recessed lighting systems, which can reduce raw material costs and shipping costs.
However, the present inventors have also recognized and appreciated several shortcomings of conventional hanger bar assemblies. For example, gaps between coupled hanger bars may cause kickback and fall, particularly when the hanger bars extend to cover large distances between adjacent support structures. In addition, hanger bars are generally different sizes; thus, conventional hanger bar holders are designed to accommodate larger hanger bars. If the housing is mounted close to the support structure, the hanger bar may need to be extended so that only one hanger bar is held by the hanger bar holder. If the smaller hanger bar is held in the hanger bar holder, a large gap may be formed between the smaller hanger bar and the hanger bar holder, resulting in instability in the hanger bar assembly.
The present disclosure is therefore directed to various inventive hanger bar assemblies that (1) interlock the hanger bars to reduce unwanted lateral kickback and descent, and (2) constrain each of the hanger bars to the hanger bar holders to reduce unwanted lateral movement between the hanger bars and the hanger bar holders.
In one example, a hanger bar assembly includes: a first hanger bar having a first interlocking structure; a second hanger bar having a second interlocking structure for interlocking with the first hanger bar; and a hanger bar holder for holding at least one of the first hanger bar or the second hanger bar. A second hanger bar is mechanically coupled to the first hanger bar such that the second hanger bar slides relative to the first hanger bar in a telescoping manner along a first axis. The first interlock structure constrains lateral movement of the second hanger bar relative to the first hanger bar along a second axis perpendicular to the first axis and a third axis perpendicular to the first axis and the second axis. The hanger bar holder also includes a frame including a first section to guide at least the first hanger bar through the hanger bar holder along a first axis and constrain lateral movement of the first hanger bar relative to the hanger bar holder along a second axis and a third axis. The frame also includes a second section to guide at least the second hanger bar through the hanger bar holder along the first axis and constrain lateral movement of the second hanger bar relative to the hanger bar holder along the second and third axes. The frame also forms a passage that partially surrounds the first hanger bar and the second hanger bar.

Detailed Description
Embodiments of the present invention will now be described in detail with reference to the drawings, which are provided as illustrative examples of embodiments so as to enable those skilled in the art to practice their clear embodiments and alternatives. It is worthy to note that the figures and examples below are not intended to limit the scope of embodiments of the present disclosure to a single embodiment, but rather other embodiments are possible by virtue of interchange of some or all of the described or illustrated elements. Furthermore, where certain elements of embodiments of the present invention may be partially or fully implemented using known components, those of such known components that are only necessary for an understanding of the embodiments of the present invention will be described, and detailed descriptions of other portions of such known components will be omitted so as not to obscure the embodiments of the present invention. In this specification, unless explicitly stated otherwise herein, embodiments showing individual components should not be considered limiting; rather, the present disclosure is intended to cover other embodiments that include a plurality of the same components and vice versa. Moreover, it is not the intention of the applicants that any term in the specification or the appended claims be ascribed an uncommon or special meaning unless explicitly set forth as such. Furthermore, embodiments of the present invention encompass current and future known equivalents to the known components referred to herein by way of illustration.
Fig. 1 shows an exploded view of an example recessed lighting system 1. The recessed lighting system 1 may comprise a junction box 2, a unitary casting 3, a rim 4, a set of hanger bars 5 and a set of hanger holders 6. In some embodiments, the unified casting 3 may contain the light source modules and drivers in a single compact unit. As will be described in further detail below, the recessed lighting system 1 provides a relatively compact and economical design that allows the light source module 3 to be moved and adjusted while complying with various building and safety codes/regulations. Each of the elements of the recessed lighting system 1 will be explained below by way of example.
The junction box 2 is a structure that separates (e.g., insulates) the internal components of the recessed lighting system 1 containing the electric wires/cables from the items inside the ceiling or low space in which the junction box 2 has been installed. In one embodiment, the junction box 2 may be a single or double junction box with a fire rating of up to two hours, as described in the National Electrical Code (NEC) and the Underwriters Laboratories (UL). The junction box 2 may receive the wires 9A from an electrical system (e.g., 120VAC or 277VAC) within the building or structure in which the recessed lighting system 1 is installed. Wires 9A from the structure may be connected to corresponding wires 9B of the unified casting 3.
Although fig. 1 shows a standard "2 x2" junction box, the junction box 2 may be implemented with an external housing, such as described in co-pending U.S. patent publication No. 2016/0312987, the contents of which are incorporated herein by reference in their entirety.
The casting 3 is a shell and/or enclosure that further prevents heat from the light source module and driver from being exposed to items (e.g., insulation) inside the ceiling or low space in which the recessed lighting system 1 has been installed. Example light source modules and drivers that may be housed in the casting 3 used in the system 1 are described in more detail in co-pending U.S. patent publication No. 2015/0009676, the contents of which are incorporated herein by reference in their entirety.
In one embodiment, wires 9A received by the junction box 2 from the electrical system of the building or structure may be coupled to wires 9B of the casting 3. As shown, the wires 9A and 9B are connected together using interlocking connectors (along with the casting 3) that may be contained within the cassette 2. However, in other embodiments, the wires 9A may be coupled to the wires 9B through the use of an electrical cover or other means, and may remain outside the cassette 2 (while the casting 3 remains inside). The wires 9B of the casting 3 may terminate in a connection with a driver 8 mounted within the casting 3. When the wires 9A and 9B are connected, power may be transferred from the power system of the building or structure to the driver to enable the driver to power the light source module.
In one embodiment, the recessed lighting system 1 may comprise a bezel 4. The main purpose of the edge strip 4 is to cover the exposed edge of the ceiling or wall where the hole of the resident recessed lighting system 1 is formed, while still allowing light from the light source module 3 to be emitted into the room through the aperture 15. In doing so, the edge strip 4 helps the recessed lighting system 1 to appear seamlessly integrated into a ceiling or wall. In one embodiment, the edge strip 4 will be attached to the casting 3, while in other embodiments the edge strip 4 will be attached to the junction box 2. The edge strips 4 may be coupled to the casting 3 and/or the junction box 2 using any connection mechanism including resin, clips, screws, bolts, or clamps. In one embodiment, the edge strips 4 may contain grooves and/or slots to couple to corresponding grooves and/or slots of the casting 3 and/or the junction box 2 using a twist-lock friction connection without the use of a separate tool or other device.
In one embodiment, the recessed lighting system 1 may comprise a set of hanger bars 5 as shown in fig. 1. The hanger bar 5 may be a rigid elongate member that is connected between adjacent joists and/or cross beams in a wall or ceiling of the structure (see fig. 2). In one embodiment, each of the hanger bars 5 may be telescopic such that each hanger bar 5 may be extended or retracted to meet the gap between the joists and/or the cross beam. In this embodiment, each hanger bar 5 may include an inner bar element 16A and an outer bar element 16B. The inner rod element 16A may be inserted and then retained within a railing structure 17 formed on the outer rod element 16B. In this configuration, the inner bar element 16A can slide relative to the outer bar element 16B to change the overall length of each hanger bar 5. In one embodiment, the railing structure 17 in the outer bar element 16B may be formed by a set of guides. The guides may be bent tabs of the outer bar element 16B or tabs coupled to the outer bar element 16B. In this way, the railing structure 17 forms a channel for the inner rod element 16A.
In one embodiment, each of the hanger bars 5 may contain a set of mounting blocks 19. The mounting blocks 19 may be used to couple the hanger bar 5 to joists and/or beams in a wall or ceiling of a structure. For example, as shown in fig. 1, the mounting block 19 may include holes for receiving screws and/or nails or other fasteners that enable the hanger bar 5 to be securely attached to the building structure. Although shown in fig. 1 and described above with respect to holes and screws, in other embodiments, other attachment mechanisms may be used in conjunction with mounting block 19, including resins, clips, or clamps, to attach rod 5 to the building structure. In one embodiment, the mounting block 19 may be integrated in an indivisible structure along with the inner and outer rod elements 16A, 16B, while in other embodiments, as shown in fig. 1, the mounting block 19 may be coupled to the inner and outer rod elements 16A, 16B using one or more attachment mechanisms (e.g., screws, bolts, resin, clips, or clamps). Using the telescoping and mounting features described above, the recessed lighting system 1 can be mounted in almost all 2"X2" to 2"X16" wood joist configurations, metal stud configurations, and t-bar ceiling configurations.
In one embodiment, the recessed lighting system 1 may include a set of hanger holders 6. The hanger holders 6 may be configured to slide or otherwise move along the corresponding hanger bar 5. In one embodiment, the hanger holder 6 may include an attachment mechanism 21 for coupling with the junction box 2. The attachment mechanism 21 may be any mechanism that allows the junction box 2 to be removably connected to the hanger bar 5. For example, as shown in fig. 1, the attachment mechanism 21 may be a hole for receiving a screw or bolt therein. However, in other embodiments, the attachment mechanism 21 may include a resin, clip, and/or clamp that allows the hanger holder 6 to be coupled to the junction box 2. By being coupled to the hanger holder 6, the junction box 2 together with the light source module and the driver therein can be moved to a desired position across the hanger bar 5, as shown in fig. 2. Thus, during installation of the recessed lighting system 1, by attaching the mounting blocks 19 to the cross beams, the hanger bar 5 may be installed within the gap between the cross beams within the structure, and then the junction box 2, with the light source modules 7 and drivers 8 therein, may be moved by the installer to a desired position along the hanger bar 5 and within the gap.
According to certain aspects, the hanger holder 6 described above allows the terminal box 2 to move in a direction parallel to the longitudinal axis of the hanger bar 5. Thus, the junction box 2 can be moved to a preferred position between a set of joists or beams in the structure and then locked into place using the mechanism 21. By being configured such that the junction box 2, with the light source modules and drivers therein, is coupled to a unified set of movable elements that help position the combined structure, the recessed lighting system 1 eliminates the increased volume and size of conventional recessed lighting systems. This compact design provides a affordable design by cutting down the cost of raw materials and other components, and reduces shipping costs by reducing volume.
While the hanger bar 5 and hanger holder 6 described above in connection with the lighting system 1 provide many advantages over conventional recessed lighting systems, the applicant has realised that there are still certain opportunities for improvement.
For example, fig. 3 is a front view of an exemplary hanger bar assembly 100 of a hanger bar 5 and a hanger holder 6, such as those shown in fig. 1 and 2. As described above and as shown in fig. 3, hanger bar 5 and hanger holder 6 are fabricated in such a way that one of the rods 16B slides telescopically over the other rod 16A to adjust various joist spacings. The holder 6 is typically made to cover the larger of the two (16B) to allow lateral movement of the junction box (not shown). When the joist spacing is large (e.g., greater than 16 inches), any gap between the slides 16A, 16B can create vertical backlash and droop in the junction box. Also, if the junction box has to be mounted close to the joist, and the holder 6 is thus only located on one of the sheets (e.g. 16A) due to the telescopic extension between the sheets 16A and 16B, there will be a large gap between the hanger bar 5 and the holder 6 at the sheet 16A, which will lead to instability.

Conclusion
While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters and configurations described herein are intended to be exemplary inventive features and that other equivalents of the specific inventive embodiments described herein may be implemented. It is, therefore, to be understood that the foregoing embodiments are presented by way of example and that, within the scope of the appended claims and equivalents thereto, embodiments of the invention may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, and/or method described herein. In addition, any combination of two or more such features, systems, articles, and/or methods, if such features, systems, articles, and/or methods are not mutually inconsistent, is included within the scope of the present disclosure.
Moreover, various inventive concepts may be embodied as one or more methods, examples of which have been provided. The actions performed as part of the method may be ordered in any suitable way. Thus, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts concurrently, even though shown as sequential acts in illustrative embodiments.
All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety.
It should be understood that all definitions, as defined and used herein, override dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of defined terms.
The indefinite articles "a" and "an", as used herein in the specification and in the claims, are to be understood as meaning "at least one" unless expressly indicated to the contrary.
As used herein in the specification and claims, the phrase "and/or" should be understood to mean "either or both" of the elements so combined, i.e., the elements are present in combination in some cases and separately in other cases. Various elements listed with "and/or" should be interpreted in the same manner, i.e., "one or more" of the elements so combined. In addition to the elements specifically identified by the "and/or" clause, other elements may optionally be present, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, when used in conjunction with open-ended language such as "including," references to "a and/or B" may refer in one embodiment to a alone (optionally including elements other than B); in another embodiment, only B (optionally including elements other than a); in yet another embodiment, refer to both a and B (optionally including other elements), and so forth.
As used herein in the specification and claims, "or" should be understood to have the same meaning as "and/or" as defined above. For example, when separating items in a list, "or" and/or "should be interpreted as inclusive, i.e., including at least one of the plurality or list elements, but also including more than one of the plurality or list elements, and optionally additional unlisted items. Only terms explicitly indicated to the contrary, such as "only one of … …" or "exactly one of … …" or "consisting of … …" when used in the claims, will refer to the inclusion of exactly one element of a plurality or list of elements. In general, the term "or" as used herein, when preceded by an exclusive term such as "either," "one of … …," "only one of … …," or "exactly one of … …," should only be construed as indicating an exclusive alternative (i.e., "one or the other but not both"). "consisting essentially of … …" when used in the claims shall have its ordinary meaning as used in the patent law field.
As used herein in the specification and claims, the phrase "at least one," when referring to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each element specifically listed in the list of elements, and not excluding any combination of elements in the list of elements. This definition also allows elements other than the element to which the specifically identified phrase "at least one" refers within the list of elements to optionally be present, whether or not related to those elements specifically identified. Thus, as a non-limiting example, "at least one of a and B" (or, equivalently, "at least one of a or B," or, equivalently "at least one of a and/or B") can refer in one embodiment to at least one, optionally including more than one, a, absent B (and optionally including elements other than B); in another embodiment, refers to at least one, optionally including more than one, B, with no a present (and optionally including elements other than a); in yet another embodiment, at least one, optionally including more than one a, and at least one, optionally including more than one B (and optionally including other elements), and the like.
In the claims, as well as in the specification above, all conjunctions such as "comprising," including, "" carrying, "" having, "" containing, "" involving, "" containing, "" consisting of … … and the like are to be understood as being open-ended, i.e., to mean including but not limited to. As described in the united states patent office patent examination program manual, section 2111.03, only the transition phrases "consisting of …" and "consisting essentially of …" should be closed or semi-closed transition phrases, respectively.
