Patent Application
20100091502
The present disclosure relates generally to housings, and more particularly to housings for lighting assemblies such as light poles, luminaires, and/or other light fixtures, and the like.
Manufacturers who ship assembled lighting fixture units for installation in industrial, commercial or residential settings often incur labor intensive assembly costs at the manufacturing and assembly plant, with the attendant result that the completed fixtures can be large and bulky. Packaging and shipping costs for the units can therefore be considered excessive. The manufacturers have therefore typically resorted to shipment separately of the fixture components or partially assembled units for assembly by the installation workers at the job site. However, the assembly, packaging and shipment separately of the housings for the light fixture units remain substantially labor intensive and costly for the manufacturer There is therefore indicated a need for light fixture housings that can be inexpensively produced and shipped and which can be easily assembled on-site by the installation workers.
The present disclosure overcomes the foregoing and other shortcomings and drawbacks of housings for luminaires, other light fixtures, and/or light poles by providing an easily assembled housing and methods of assembly of such housings, for which snap fit connections are utilized
In accordance with the teachings of the present disclosure, snap fittings or connections can be placed on portions of a housing to allow assembly of the housing in the field, without the need for tools and/or hardware for assembly or the need for welding Reduced assembly time and cost, as well as the reduction/elimination of tooling costs for assembly tools can therefore be realized.
Exemplary embodiments of the present disclosure can include a snap fitting with first and second portions, eggs, male and female portions, including a portion having a tab or clip punched out of a sheet and including a holding protrusion or portion, and another portion having an aperture or depression configured and arranged to receive and be held by the holding portion
While aspects of the present disclosure are described herein in connection with certain embodiments, it is noted that variations can be made by one with skill in the applicable arts within the spirit of the present disclosure and the scope of the appended claims.
Aspects and embodiments of the present disclosure may be more fully understood from the following description when read together with the accompanying drawings, which are to be regarded as illustrative in nature, and not as limiting The drawings are not necessarily to scale, emphasis instead being placed on the principles of the disclosure. In the drawings:
While certain embodiments are depicted in the drawings, the embodiments depicted are illustrative and variations of those shown, as well as other embodiments described herein, may be envisioned and practiced within the scope of the present disclosure.
Aspects and embodiments of the present disclosure provide housings that are easily assembled by personnel in the field without the need for any hardware, assembly tools, or welding for the assembly process. Additional benefits may be provided by eliminating/mitigating needs for machine tooling maintenance for assembly hardware The housings can include snap fittings or other interlocking/intermeshing connections, thus eliminating any need for assembly tools and maintenance equipment/tooling for such tools.
As shown in
In exemplary embodiments, connection portions 122, 124, 126, and 128, and portions 122′, 124′, 126′, and 128′ can be snap fit connection components as shown in
As shown in
In alternate embodiments, a hinge 150 may be provided to a housing to facilitate installation. For such embodiments, snap fit connections are not necessary for the adjacent portions of the housing, thus reducing the number of snap fittings required. For certain applications/embodiments employing hinges, features of the hinges may render the pieces/portions of the housing asymmetrical (whereas embodiments without hinges are/can be symmetrical, thus possibly increasing manufacturing costs.
Exemplary embodiments may utilize any of the following materials for the housing and/or connection parts: aluminum, pre-painted aluminum, cold roll steel, hot roll steel, hot roll steel-pickled and oiled, galvanized steel, galvannealed steel, paint grip steel, pre-painted steel, and/or stainless steel. Any suitable finish (erg., paint or powder coat, etc,) may be used for the housing parts/portions.
As shown in
Each offset tab (e.g., tab 304) includes a dimple (e.g., dimple 308) that protrudes from the tab in a direction toward the parent form or sheet. The connection includes one or more adjacent second (in-line or hole) tabs 306 (one is shown) with a hole 310, connected to the parent form or sheet 302
In will be understood that, with regard to pieces 302 and 320, while each is shown with a single offset tab and an adjacent in-line tab, that any number of such offset and in-line tabs may be used for a connection. For example, two in-line tabs could flank a single offset tab; the corresponding mating piece would consequently have two offset tabs and a single in-line tab. For additional, and non-limiting example, each mating housing piece could include two offset tabs and two in-line tabs for a connection. While less preferred, a connection could also include a single in-line tab on one piece and a single offset tab on the mating piece. Other configurations and/or numbers of such tabs can be used as desired.
With continued reference to
Exemplary embodiments of the present disclosure can utilize interlocking connections in which a tab or tongue has been pinch-pressed out of a sheet of metal; this tab can be displaced by a desired distance from the parent sheet of metal. The tab can be configured and arranged to have a desired angle or angles between the parent sheet. In exemplary embodiments, the tab can have a dimple or depression/protrusion that can fit within a depression or aperture, e.g., hole, in a mating piece. In exemplary embodiments, SNAPLOCK™ fabricated joints made commercially available by Mate Precision Tooling Inc, with business offices at 1295 Lund Blvd., Anoka, Minn. 55303, USA, can be used for snap fit connections in accordance with the present disclosure.
Accordingly, the connections afforded by embodiments of the present disclosure can allow different types of materials (e.g., different metals, plastics) to be joined. The joined materials can have different thickness. Welding is not necessary, and no tools are necessary for assembly.
While certain embodiments have been described herein, it will be understood by one skilled in the art that the methods, systems, and apparatus of the present disclosure may be embodied in other specific forms without departing from the spirit thereof. For example, while aspects and embodiments herein have been described in the context of sheets when referring to the housing portions, other materials and structures may of course be realized and utilized within the scope of the present disclosure. Such housing portions are not limited to thin materials and may be of a desired thickness and/or materials) suitable for a housing.
Additionally, while the housings described herein have largely been referred to in the context of light fixture housings, the present disclosure is not limited to such, and can be used to provide housings to many other items, systems, assemblies, and spaces as desired. Further, while the housing portions have been described in the context of including one or more apertures to receive the base of a light pole, such housing may be configured and utilized for virtually any covering purpose or to contain or protect most anything. And, while metals have been described for the housing materials, the present disclosure can include use of other suitably rigid and strong or durable materials such as plastics and/or composites (e.g., fiberglass ), etc.
Accordingly, the embodiments described herein, and as claimed in the attached claims, are to be considered in all respects as illustrative of the present disclosure and not restrictive.
