- PEIO-component-connector-cable-hole cover 86 may be hingedly mounted to base 12 instead of mounted to slide between an open and a closed position.
- a hingedly mounted PEIO-component-connector-cable-hole cover may rotate between an open position and a substantially closed position (e.g., in the Y-Z plane) to allow component cable 30 to be extended between an interior of shelter 10 and an exterior of shelter 10 .
- Other configurations of PEIO-component-connector-cable-hole cover 86 are possible.
- PEIO-component-connector-cable-hole cover 86 may define a cutout 88 ( FIG. 2 ) that corresponds to a size and/or shape of component cable 30 . Cutout 88 may help prevent component cable 30 from being compressed when PEIO-component-connector-cable-hole cover 86 is moved to a substantially closed position. In some examples, the portion of PEIO-component-connector-cable-hole cover 86 that defines cutout 88 may be positioned over platform 34 when PEIO-component-connector-cable-hole cover 86 is closed and there is no component cable extending through the PEIO-component-connector-cable hole.
- PEIO-component-connector-cable-hole cover 86 may slide beyond PEIO-component-connector-cable hole 80 A (i.e., to the left of the illustration in the Y-direction) when moved in a closed position.

- Support structures 104 permanently affix hinge pin 106 to sidewall 36 and align hinge pin 106 parallel to sidewall 36 .
- Hinge pin 106 defines a first end projection 108 projecting from support structure 104 A (i.e., in the X-direction) and a second end projection 110 projection from support structure 104 D (i.e., in the X-direction opposite first end projection 108 ).
- Hinge pin 106 and first and second end projections 108 and 110 of hinge pin 106 can be inserted into hinge section 100 ( FIG. 4A ) to assemble hinge 38 .

Abstract
Description
- The present application is a continuation of U.S. patent application Ser. No. 12/967,729, filed Dec. 14, 2010, which application is incorporated herein by reference.
- This disclosure relates to electrical connectors and, more particularly, to shelters for electrical connectors.
- Portable electrical inlets/outlets (“PEIO”) are used in many settings in which access to electricity must be provided on a temporary basis. Examples of such settings include trade shows, concerts, and other similar events. During operation, a PEIO may supply electrical power from a readily available power source, such as a permanently mounted wall socket or a portable power generator, to one or more pieces of electrical equipment. For example, common types of PEIOs include extensions cords, power strips, and outlet splitters. An example of another type of PEIO used in some applications is a quad box. A quad box generally includes a power inlet cable, a power outlet cable, and one or more connectors for connecting electrical equipment to the quad box. In some applications, the power outlet cable of one quad box may function as the power inlet cable of another quad box to create a distributed power network.
- PEIOs are often used in public settings, such as outdoor settings subject to inclement weather. Accordingly, a PEIO may be exposed to standing water, inclement weather, ground debris, kicking, and other deliberate or inadvertent physical contact during operation. Ensuring that a PEIO is kept clean, dry, and free from contact by people or animals may be useful for the safe and intended operation of a PEIO.
- Prior attempts at sheltering PEIOs have been made. Examples can be found in the teaching of U.S. Pat. Nos. 6,250,946 and 4,702,541, and U.S. Design Pat. No. 284,465. Such attempts have been inadequate at suitably protecting PEIOs for a variety of reasons. Additionally, PEIOs that operate in an outdoor environment are often wrapped in a plastic bag (e.g., a garbage bag) that is taped in an attempt to protect the PEIOs from unwanted outdoor elements. This method of protection is not particularly effective nor is it especially aesthetically pleasing in a public setting.
- The disclosure is directed toward shelters for protecting PEIOs from unwanted elements such as, e.g., moisture, debris, and contact by people or animals. In some examples, the shelters protect a PEIO by physically encasing the PEIO in a material resistant to physical and environmental elements. In some additional examples, the shelters include legs, a stand, or other features that elevate the shelter (and hence a PEIO positioned in the shelter) above a surface on which the PEIO is set. These elevating features can protect the PEIO from water should water accumulate on the surface on which the shelter is set. In the event that water enters a shelter, the shelter may include features to segregate the PEIO from water that accumulated inside the shelter. For example, the shelter may include features that elevate the PEIO above a floor of the shelter so that water passes around or under the PEIO without substantially contacting the water. As another example, the shelter may include a drain hole to drain accumulated water out of the shelter. The shelter may include additional or different features, as described herein.
- In accordance with one example described herein, a shelter for protecting a PEIO from unwanted elements, where the PEIO includes a PEIO body, first and second PEIO cables, and at least two PEIO-component connectors is described. The shelter includes a base that includes a platform to support the PEIO body and at least one sidewall. The platform includes a main area and a raised rib structure configured to segregate the PEIO body from water that may accumulate in the main area. The at least one sidewall extends substantially around at least a portion of a perimeter of the platform. The shelter also includes a cover that is configured to mate with the base to substantially enclose the platform. According to the example, the shelter defines at least two PEIO-component-connector-cable holes configured to permit component cables to extend from an exterior of the shelter to the at least two PEIO-component connectors within the shelter. The shelter also defines a first PEIO-cable hole and a second PEIO-cable hole, the first and second PEIO-cable holes being configured to permit the first and second PEIO cables to extend from the PEIO body within the shelter to an exterior of the shelter.
- In another example, a system includes a PEIO, a shelter, and a component cable. The PEIO includes a PEIO body, a first PEIO cable, a second PEIO cable, and at least two PEIO-component connectors. The shelter includes a base that includes a platform to support the PEIO body and at least one sidewall. The platform includes a main area and a raised rib structure that is configured to segregate the PEIO body from water that may accumulate in the main area. The at least one sidewall extends substantially around at least a portion of a perimeter of the platform. The shelter also includes a cover configured to mate with the base to substantially enclose the platform. The shelter defines a first PEIO-cable hole, a second PEIO-cable hole, and at least two PEIO-component-connector-cable holes. According to the example, the PEIO is positioned such that the PEIO body is adjacent the raised rib structure of the shelter, the first PEIO cable extends from the PEIO body through the first PEIO-cable hole to an exterior of the shelter, the second PEIO cable extends from the PEIO body through the second PEIO-cable hole to the exterior of the shelter, and the component cable extends from one of the at least two PEIO-component connectors through one of the at least two PEIO-component-connector-cable holes to the exterior of the shelter.
- In another example, a method is described that includes providing a shelter that includes a base and a cover. The base includes a platform to support the PEIO body, the platform including a main area and a raised rib structure configured to segregate the PEIO body from water that may accumulate in the main area, and at least one sidewall extending substantially around at least a portion of a perimeter of the platform. The shelter also includes a first PEIO-cable hole, a second PEIO-cable hole, and at least two PEIO-component-connector-cable holes. According to the example, the method includes inserting a PEIO that includes a PEIO body, a first PEIO cable, a second PEIO cable, and at least two PEIO-component connectors into the shelter, and mating the cover of the shelter to the base of the shelter to substantially enclose the PEIO body within the shelter.
- The details of one or more examples are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description and drawings, and from the claims.

Rather, the following description provides practical illustrations for implementing exemplary embodiments of the present invention. Examples of constructions, materials, dimensions, and manufacturing processes are provided for selected elements, and all other elements employ that which is known to those of skill in the field of the invention. Those skilled in the art will recognize that many of the examples provided have suitable alternatives that can be utilized.
- PEIOs can distribute power from a readily available power source, such as a permanently mounted wall socket or a portable power generator, to one or more pieces of electrical equipment. For example, a PEIO may include a connector for electrically connecting to a power source as well as one or more component connectors (e.g., plug receptacles) to which electrical equipment can be electrically connected. Because a PEIO can be used for power distribution, PEIOs are often used at public events, such as trade shows, concerts, and other similar events. Depending on the type of event, a PEIO may be used in an outdoor setting. Accordingly, a PEIO may be exposed to standing water, inclement weather, ground debris, kicking, scratching, and other inadvertent physical contact during operation.
- This disclosure describes a shelter for a PEIO. The shelter may protect the PEIO from unwanted elements such as, e.g., debris and unintended contact by people or animals. The shelter may also protect the PEIO from moisture that could otherwise create a short circuit. For instance, in one example, the PEIO includes a platform that includes a raised rib structure that is capable of segregating the PEIO from water that may accumulate in a main area of the platform. In another example, the PEIO includes an elevating portion that extends downwardly from a platform and that is capable of elevating the platform from a surface on which the shelter is set. Upon inserting the PEIO into the shelter, the elevating portion can elevate the PEIO above a surface. Should water accumulate on the surface on which the shelter and the PEIO is positioned, the elevating portion may prevent the PEIO from being exposed to water.
- In an additional example, the shelter includes a cover that can be mated with a base to substantially enclose a platform that supports the PEIO. Depending on the configuration of the shelter, the shelter may substantially enclose the PEIO within a confined space that is bounded on all sides by the shelter. In such a configuration, the shelter may help protect the PEIO from inadvertent physical contact, such as being kicked, being stepped on, or the like.
- Different views of an example shelter will be described in greater detail with reference to
FIGS. 2-6 . However, an example PEIO and an example shelter will first be described with reference toFIG. 1 . -
FIG. 1 is conceptual view of anexample shelter 10 in accordance with this disclosure.Shelter 10 includesbase 12 andcover 14.Base 12 is configured to supportPEIO 16.PEIO 16 can be positioned ontobase 12, and cover 14 can be positioned overbase 12 to substantially encase PEIO 16 withinshelter 10.Shelter 10 may help protect PEIO 16 from a variety of unwanted elements including, e.g., unintended contact by people or animals, and inclement weather. For example, as described in greater detail below,shelter 10 may include features that help protect PEIO 16 from moisture that may otherwiseshort circuit PEIO 16. In one example,shelter 10 includes a rib structure (FIG. 2 ) that is configured to segregatePEIO 16 from water that may accumulate in a main area ofbase 12. In another example, PEIO includes an elevating portion (FIGS. 1 and 2 ) that extends downwardly and that is configured to elevate base 12 from a surface on whichshelter 10 is set.Shelter 10 may include additional or different features, as described below. -
Shelter 10 is configured to supportPEIO 16. In general,PEIO 16 may be any device that includes a power inlet that is configured to electrically connect with a power source, and a power outlet that is configured to electrically connect with an electrical component. In the example ofFIG. 1 ,PEIO 16 is generally illustrated in the style of a quad box. A quad box may be a junction box that electrically connects at least one electrical inlet to a plurality of different electrical outlets (e.g., two, three, four or more electrical outlets). In some examples, a quad box may include a plurality of modular PEIO-component connectors (described in greater detail below), each of which may be replaced, e.g., to repair or reconfigure the quad box. - Because
PEIO 16 is generally illustrated in the style of a quad box inFIG. 1 , the remainder of the present disclosure generally refers to an example configuration ofshelter 10 that is designed to receive a quad box. However, other configurations ofshelter 10 are possible in accordance with the present disclosure and it should be appreciated that the disclosure is not limited to any particular type of PEIO. For example,PEIO 16 may be an extension cord, a power strip, or an outlet splitter, each of which can include a power inlet (e.g., male connector) and one or more power outlets (e.g., female connector). - In the example of
FIG. 1 , which generally depicts a quad box-style PEIO,PEIO 16 includes aPEIO body 18, afirst PEIO cable 20, asecond PEIO cable 22, and at least one PEIO-component connector 24, which in the example ofFIG. 1 is illustrated as four PEIO-component connectors (collectively “connectors 24,” only one of which is labeled for clarity).First PEIO cable 20 electrically connectsPEIO body 18 to a power source such as, e.g., a permanently mounted wall socket or a portable power generator.First PEIO cable 20 may directly connectPEIO body 18 to a power source (e.g., without any intervening components) or indirectly connectPEIO body 18 to a power source (e.g., through another PEIO body).Second PEIO cable 22 electrically connectsPEIO body 18 to another PEIO body (not illustrated) to create an in-line series of PEIO boxes connected to a common power source. Depending on the configuration ofPEIO 16,first PEIO cable 20 andsecond PEIO cable 22 may each be permanently attached toPEIO body 18, or one or both offirst PEIO cable 20 andsecond PEIO cable 22 may be detachable fromPEIO body 18. For example, as seen inFIG. 1 ,first PEIO cable 20 andsecond PEIO cable 22 may be detachably connected toPEIO body 18 via threadedconnectors first PEIO cable 20 andsecond PEIO cable 22 toPEIO body 18. For instance,PEIO body 18 may include male electrical connectors (e.g., two or three-prong electrical connectors) andfirst PEIO cable 20 and/orsecond PEIO cable 22 may include corresponding female electrical connectors which can be friction fit over the male connectors ofPEIO body 18. -
First PEIO cable 20 andsecond PEIO cable 22 can have any suitable dimensions and can be configured to carry any suitable amount and type of electricity. In different examples,first PEIO cable 20 andsecond PEIO cable 22 can carry single-phase alternating current (AC), three-phase AC, or direct current (DC). In some examples,first PEIO cable 20 andsecond PEIO cable 22 are each capable of electrically conveying at least conventional 110 volt/120 volt electricity from a standard wall socket. In some additional examples,first PEIO cable 20 andsecond PEIO cable 22 are each capable of electrically conveying higher voltages such as, e.g., 220 volt single-phase AC current, or 208 volt three-phase current. In yet additional examples,first PEIO cable 20 andsecond PEIO cable 22 are each configured to electrically convey less than or equal to approximately 600 volts. -
PEIO 16 also includes PEIO-component connectors 24. Each component connector of PEIO-component connectors 24 is capable of electrically connecting to a component that operates on electrical energy. For instance, in the example ofFIG. 1 , each component connector of PEIO-component connectors 24 is a port defined by PEIO body 18 (e.g., a female connector) that is configured to receive a corresponding plug 28 (e.g., male connector) disposed at a distal end of acomponent cable 30. In some examples, each component connector of PEIO-component connectors 24 may be designed to receive a multi-prong plug such as, e.g., a two or three-prong electrical plug found on some standard extension cords, or a four or five-prong electrical plug found in some commercial applications. Each component connector of PEIO-component connectors 24 may be the same as each other component connector of PEIO-component connectors 24, or at least one component connector of PEIO-component connectors 24 may be different than at least one other component connector of PEIO-component connectors 24. For example, as noted above,PEIO 16 may include modular PEIO-component connectors that can be reconfigured, e.g., by replacing one style of PEIO-component connector with a different style of PEIO-component connector. Other configurations of PEIO-component connectors 24 are contemplated, however, and any suitable PEIO-component connector may be used in accordance with the disclosure. For instance, in another example, each connector of PEIO-component connectors 24 may be a protruding connection extending from PEIO body 18 (e.g., a male connector configured to receive a corresponding female connector). - In the example of
FIG. 1 ,PEIO 16 includes four PEIO-component connectors 24. Specifically,PEIO 16 includes two, outwardly-facing, side-by-side PEIO-component connectors arranged on one side ofPEIO body 18 and two different, outwardly-facing, side-by-side PEIO component connectors arranged on an opposing side ofPEIO body 18. As a result,PEIO 16 provides two sets of oppositely facing PEIO-component connectors. The number, type, and arrangement of PEIO-component connectors 24 may vary, e.g., based on the type of electrical components that PEIO 16 is intended to supply power for. For example,PEIO 16 may include fewer PEIO-component connectors (e.g., one or two), more PEIO-component connectors (e.g., five or more), or a different physical arrangement of PEIO-component connectors than illustrated inFIG. 1 . - As seen in the example
FIG. 1 , in some applications, each PEIO-component connector or each set of PEIO-component connectors ofPEIO 16 may include acover 32 that rotates relative toPEIO body 18.Such cover 32 may protect each PEIO-component connector from dirt, debris, or the like when plug 28 is not inserted into the component connector. - Each PEIO-component connector of
PEIO 16 may be electrically connected to a component cable, such ascomponent cable 30. In general,component cable 30 is an electrically conductive cable that includes an electrically insulative exterior. Depending on the configuration ofPEIO 16,component cable 30 may be a standard extension cord that plugs in toPEIO body 18 at one of PEIO-component connectors 24 and that extends to a component that operates on electrical energy, orcomponent cable 30 may be non-standard cable that is capable of conducting electrical energy. - In operation,
PEIO 16 can distribute power from a power supply to one or more electrically connected components. In one example, power entersPEIO body 18 viafirst PEIO cable 20 and is split between each PEIO-component connectors of PEIO-component connectors 24 andsecond PEIO cable 22. In such an example,PEIO body 18 may house various hardware to, e.g., split, step-up, and/or step-down the electricity enteringPEIO body 18. In another example,first PEIO cable 20 encases electrically isolated wires that are separately electrically connected to each of PEIO-component connectors 24 andsecond PEIO cable 22.PEIO 16 may have other configurations as well. - To help protect PEIO 16 from unwanted elements,
PEIO 16 may be positioned inshelter 10 in accordance with this disclosure.Shelter 10 can assume different configurations; however, in the example ofFIG. 1 ,shelter 10 includesbase 12 andcover 14.Base 12 includesplatform 34 andsidewall 36.Platform 34 provides physical support forPEIO body 18 whenPEIO 16 is inserted intoshelter 10.Sidewall 36 extends substantially around the perimeter ofplatform 34 to define a cavity that is configured to receivePEIO 16.Cover 14 is configured to mate withbase 12 to substantially encloseplatform 34. Specifically, in the example ofFIG. 1 , cover 14 is pivotally mounted tobase 12 viahinge 38 and is configured to mate with an upper surface ofsidewall 36. Although in other examples, cover 14 may not be affixed to base 12 (e.g., via hinge 38) but can instead be simply placed on top ofbase 12. InFIG. 1 ,PEIO 16 can be inserted intobase 12, and cover 14 can close overPEIO body 18 to help protectPEIO body 18 within a bounded cavity defined byplatform 34,sidewall 36, and cover 14. By positioningPEIO body 18 betweenbase 12 andcover 14,shelter 10 may provide protection to substantially the entire PEIO body, e.g., to prevent damage from dropping, scratches, or other physical abuse. Further, as will be described in greater detail with respect toFIG. 2 ,shelter 10 may include various features to help preventPEIO body 18 from being exposed to moisture during operation. - As shown in
FIG. 1 ,shelter 10 receivesPEIO 16 by positioningPEIO body 18 onplatform 34.Platform 34 physically supportsPEIO body 18 withinshelter 10.Platform 34 may define any suitable size and shape, and the size and shape ofplatform 34 may vary, e.g., based on the size and shape ofPEIO body 18. For example,platform 34 may define a planar surface or a non-planar surface, as described in greater detail below with respect toFIG. 2 . In some examples,PEIO 16 mechanically attaches toplatform 34, e.g., by mechanically attaching a bottom surface ofPEIO body 18 toplatform 34. For instance, a mechanical fixation element such as, e.g., bolts, screws, adhesive, or the like may be used to mechanically attachPEIO 16 toplatform 34. In other examples,PEIO 16 is supported onplatform 34 without being mechanically affixed toplatform 34. For instance, in the example shown inFIG. 1 ,PEIO 16 is positioned onplatform 34 and cover 14 may rotate closed over PEIO 16 to frictionfit PEIO 16 betweenbase 12 andcover 14. Such an arrangement may preventPEIO 16 from moving out of alignment withbase 12 afterPEIO 16 is positioned withinshelter 10. - In the example of
FIG. 1 ,base 12 includes at least onesidewall 36, which is illustrated as four interconnected sidewalls that surround a substantially rectangular-shapedplatform 34.Sidewall 36 extends upwardly (i.e., in the Z-direction indicated onFIG. 1 ) fromplatform 34.Sidewall 36 may help protect the sides ofPEIO body 18 from unintended contact and may also define a surface that can mate withcover 14. In some examples, as illustrated inFIG. 1 ,sidewall 36 extends around substantially the entire perimeter of platform 34 (i.e., in the X-Y plane indicated onFIG. 1 ). In other examples,sidewall 36 extends around less than the entire perimeter ofplatform 34. For example,base 12 may include a plurality of discrete sidewall segments that are physically separated from one another aroundplatform 34. In yet other examples,base 12 may not includesidewall 36. In such an example,PEIO 16 may be positioned onplatform 34 and cover 14 may be configured (e.g., sized and shaped) with a cavity that may be arranged over PEIO 16 such that cover 14 mates withbase 12 around a perimeter ofplatform 34. - While
base 12 is illustrated as defining a substantially rectangular shape, in other examples base 12 can define other shapes.Base 12 can define any polygonal (e.g., square, hexagonal) or arcuate (e.g., circular, elliptical) shape, or even combinations of polygonal and arcuate shapes. The specific shape ofbase 12 may vary, e.g., based on the specific shape ofPEIO 16. - In operation,
base 12 ofshelter 10 may be placed on a surface that is exposed to unwanted elements from above (i.e., in the Z-direction indicated onFIG. 1 ) such as, e.g., rain, snow, or inadvertent contact. For this reason,shelter 10 may include a cover that mates withbase 12 to help protect PEIO 16 from above.Shelter 10 may include any suitable cover including, e.g., a cover that mates withbase 12 such that there is substantially no separation gap between the cover andbase 12. Such a cover may prevent unwanted elements from enteringshelter 10 from the sides of the shelter (i.e., in the X-Y plane). - In the example of
FIG. 1 , cover 14 includestop surface 40 and at least one cover-sidewall 42, which is illustrated as four interconnected cover-sidewalls that surround a substantially rectangular-shaped top surface. Cover-sidewall 42 extends downwardly (i.e., in the Z-direction indicated onFIG. 1 ) fromtop surface 40.Top surface 40 may be planar as illustrated inFIG. 1 or non-planar (e.g., domed, peaked, or the like). A non-planartop surface 40 may help repel unwanted elements fromtop surface 40 and may help prevent water or debris from collecting ontop surface 40. - As with
sidewall 36 ofbase 12, cover-sidewall 42 may help protect the sides ofPEIO body 18 from unintended contact whenPEIO 16 is inserted intoshelter 10. In some examples, as illustrated inFIG. 1 , cover-sidewall 42 extends around substantially the entire perimeter of top surface 40 (i.e., in the X-Y plane indicated onFIG. 1 ).Cover 14 may define a size and shape that substantially corresponds to a size and shape ofbase 12. In such an example, cover 14 may mate withbase 12 when an edge of cover-sidewall 42 is positioned adjacent an edge ofsidewall 36 ofbase 12. In other examples, cover 14 does not include cover-sidewall 42. For example, cover 14 may instead be a planar sheet. In such an example,top surface 40 ofcover 14 may be positioned directlyadjacent base 12 to encase PEIO 16 withinshelter 10. - In some examples, cover 14 may include a lip that extends over an edge of
base 12 whencover 14 is mated to base 12. For instance, in the example ofFIG. 1 , cover 14 includes lip 17 (also illustrated inFIG. 2 ) that extends around a perimeter of cover-sidewall 42 and that projects outward (i.e., in the X and Y-directions) and downward (i.e., in the Z-direction) from a bottom edge of cover-sidewall 42. Whencover 14 is mated withbase 12,lip 17 extends down oversidewall 36 ofbase 12 so that any rain that falls oncover 14 flows off cover-sidewall 42 without enteringshelter 10 at the junction betweencover 14 andbase 12. - As discussed above with respect to
base 12, cover 14 can define shapes other than the substantially rectangular shape illustrated inFIG. 1 . For example, cover 14 can define any polygonal (e.g., square, hexagonal) or arcuate (e.g., circular, elliptical) shape, or even combinations of polygonal and arcuate shapes. The specific shape ofcover 14 may vary, e.g., based on the specific shape of PEIO 16 and/or the specific shape ofbase 12. - The specific dimensions of
shelter 10 may vary, e.g., based on the specific dimensions ofPEIO 16. That being said, in some examples,shelter 10 may includecover 14 that is between approximately 25 centimeters and approximately 45 centimeters long (i.e., in the Y-direction), such as approximately 35 centimeters, between approximately 16 centimeters and approximately 36 centimeters wide (i.e., in the X-direction), such as approximately 26.5 centimeters, and between approximately 1 centimeter and approximately 10 centimeters tall (i.e., in the Z-direction), such as approximately 4.5 centimeters. In some examples,shelter 10 may includebase 12 that is between approximately 25 centimeters and approximately 45 centimeters long (i.e., in the Y-direction), such as approximately 35 centimeters, between approximately 16 centimeters and approximately 36 centimeters wide (i.e., in the X-direction), such as approximately 26.5 centimeters, and between approximately 1 centimeter and approximately 25 centimeters tall (i.e., in the Z-direction), such as approximately 11.5 centimeters. These dimensions are merely examples, however, and other dimensions are both contemplated and possible. -
Shelter 10 may be subject to different physical abuses during the service life of the shelter. At various times,shelter 10 may be dropped, kicked, scratched, abraded, or otherwise abused.Shelter 10 may protectPEIO 16 from these and other physical abuses. As such,shelter 10 may be constructed of a robust material able to withstand different physical forces without breaking. In various examples,shelter 10 may be constructed of a metal material (e.g., steel, aluminum, copper), a thermoplastic material (e.g., polystyrene, polyethylene, polypropylene, polyvinyl-based materials), a thermosetting plastic material (e.g., Bakelite, epoxy resin-based materials), or the like. In one example,shelter 10 is constructed of polypropylene, which may remain flexible and which may be substantially resistant to UV-radiation in outdoor applications. Other materials forshelter 10 are both possible and contemplated. - As described above,
PEIO 16 includesfirst PEIO cable 20 andsecond PEIO cable 22. WhenPEIO body 18 is positioned withinshelter 10,first PEIO cable 20 andsecond PEIO cable 22 may electrically connectPEIO body 18 to components located outside ofshelter 10. For this reason,shelter 10 may include one or more apertures that define openings for physically and/or electrically connectingPEIO body 18 to features located outside ofshelter 10. The number and arrangement of the different apertures may vary, e.g., based on the specific configuration ofshelter 10 and the specific configuration ofPEIO 16. However, with respect to the example ofFIG. 1 ,shelter 10 defines a first PEIO-cable hole 44A and a second PEIO-cable hole 44B (which inFIG. 1 are denoted by labeled double-headed arrows, indicating that first PEIO-cable hole 44A and second PEIO-cable hole 44B are defined whencover 14 is mated to base 12). First PEIO-cable hole 44A is configured (e.g., sized and shaped) to permitfirst PEIO cable 20 to extend fromPEIO body 18 to an exterior ofshelter 10, while second PEIO-cable hole 44B is configured (e.g., sized and shaped) to permitsecond PEIO cable 22 to extend fromPEIO body 18 to an exterior ofshelter 10. - First PEIO-
cable hole 44A and second PEIO-cable hole 44B can be arranged at any suitable location onshelter 10. In different examples, first PEIO-cable hole 44A and/or second PEIO-cable hole 44B may be defined entirely bybase 12 ofshelter 10, entirely bycover 14 ofshelter 10, or in yet another location ofshelter 10. For instance, in the example ofFIG. 1 , first PEIO-cable hole 44A and second PEIO-cable hole 44B are located at an interface betweenbase 12 andcover 14. Specifically,base 12 defines a first base-PEIO-cable partial-hole 46A and a second base-PEIO-cable partial-hole 46B, which are lesser portions of first PEIO-cable hole 44A and second PEIO-cable hole 44B, respectively.Cover 14 defines a first cover-PEIO-cable partial-hole 48A and a second cover-PEIO-cablepartial hole 48B that correspond to first base-PEIO-cable partial-hole 46A and second base-PEIO-cable partial-hole 46B, respectively. First cover-PEIO-cable partial-hole 48A and second cover-PEIO-cablepartial hole 48B are lesser portions of first PEIO-cable hole 44A and second PEIO-cable hole 44B, respectively. Whencover 14 is mated with base 12 (e.g., brought into adjacent alignment) first base-PEIO-cablepartial hole 46A aligns with first cover-PEIO-cablepartial hole 48A to create first PEIO-cable hole 44A, while second base-PEIO-cablepartial hole 46B aligns with second cover-PEIO-cablepartial hole 48B to create second PEIO-cable hole 44B. With this arrangement,first PEIO cable 20 andsecond PEIO cable 22 can extend fromPEIO body 18 to an exterior ofshelter 10 through first PEIO-cable holes first PEIO cable 20 andsecond PEIO cable 22 may be friction fit betweenbase 12 and cover 14 in such an arrangement, which may preventPEIO 16 from moving out of alignment with respect tobase 12 afterPEIO 16 is positioned withinshelter 10. -
Shelter 10 can define a first PEIO-cable hole 44A and a second PEIO-cable hole 44B of any suitable size and shape. In some examples, as described in greater detail with reference toFIGS. 3A and 3B ,shelter 10 can define a first PEIO-cable hole 44A and/or a second PEIO-cable hole 44B that is adjustable to accommodate PEIOs with different size cables. An adjustable cable hole may provide a tighter fit between a cable andshelter 10 than a non-adjustable cable hole, which may reduce the ingress of unwanted elements intoshelter 10 through the cable hole. - In some examples,
shelter 10 includes a support surface adjacent to first PEIO-cable hole 44A and/or second PEIO-cable hole 44B that functions to supportfirst PEIO cable 20 and/orsecond PEIO cable 22, respectively.FIG. 1 illustrates an example ofshelter 10 that includes example support surfaces. - In the example of
FIG. 1 ,shelter 10 includes base-PEIO-cable partial-support sidewall 36 ofbase 12. Base-PEIO-cable partial-supports 50 are aligned with first and second base-PEIO-cable partial-holes First PEIO cable 20 andsecond PEIO cable 22 can extend through first and second base-PEIO-cable partial-holes base 12adjacent sidewall 36. - When configured as shown in
FIG. 1 , cover 14 includes complementary cover-PEIO-cable partial-supports sidewall 42 and that are aligned with first and second cover-PEIO-cable partial-holes cover 14 is mated withbase 12, cover-PEIO-cable partial-supports supports first PEIO cable 20 is extended through first PEIO-cable hole 44A andsecond PEIO cable 22 is arranged through second PEIO-cable hole 44B, first andsecond PEIO cables support supports adjacent cable connectors PEIO 16. - While
shelter 10 in the example ofFIG. 1 includes support surfaces on bothbase 12 andcover 14, it should be appreciated that in other examples according to the disclosure, a shelter may include support surfaces that extend only frombase 12 or extend only fromcover 14. The arrangement and location of support surfaces in these examples may be dictated by the arrangement and location of PEIO-cable holes -
Shelter 10 may include a variety of different features that may help protect PEIO 16 from unwanted elements. For instance, in some applications,PEIO 16 may be used in an outdoor environment subject to inclement weather such as rain and snow. WhenPEIO 16 is exposed to moisture from inclement weather, the moisture may cause short circuits that reduce the electrical integrity ofPEIO 16. To reduce or eliminate water accumulationadjacent PEIO 16 in these applications,shelter 10 may include moisture management features. -
FIG. 2 is a conceptual illustration of one example ofshelter 10, generally described above with respect toFIG. 1 , which includes example moisture management features. InFIG. 2 , like reference numerals betweenFIGS. 1 and 2 refer to like elements. Further, for ease of description,PEIO 16 is not illustrated withinshelter 10 in the example ofFIG. 2 . - In the example of
FIG. 2 ,platform 34 ofshelter 10 includes amain area 37 and a raisedrib structure 39. Raisedrib structure 39 may segregate PEIO 16 (FIG. 1 ) from moisture that may accumulate onmain area 37. Raisedrib structure 39 extends upwardly (i.e., in the Z-direction) frommain area 37 ofplatform 34. Accordingly, PEIO body 18 (FIG. 1 ) can be positioned on raised rib structure to elevatePEIO body 18 abovemain area 37 ofplatform 34. Should water accumulate onmain area 37 ofshelter 10, raisedrib structure 39 can segregatePEIO body 18 from the accumulated water, which may reduce or eliminate the possibility of a short circuit betweenPEIO body 18 andcomponent cable 30. - Depending on the configuration of
shelter 10, raisedrib structure 39 may be a single rib (i.e., a single elevating feature that functions to elevatePEIO body 18 above main area 37), or a plurality of rib features. For instance, in the example ofFIG. 2 , raisedrib structure 39 includes six ribs that are arranged in parallel alignment and that are substantially equally spaced from one another. It should be appreciated, however, that the disclosure is not limited in this respect, and other configurations ofrib structure 39 are both possible and contemplated. - Independent of the specific configuration of
rib structure 39, in some examples,rib structure 39 may elevatePEIO body 18 at least 2 millimeters abovemain area 37. WhenPEIO body 18 is elevated at least 2 millimeters abovemain area 37, the likelihood thatPEIO body 18 will be immersed in water withinshelter 10 may be reduced or eliminated. It should be appreciated though thatrib structure 39 may elevatePEIO body 18 to heights other than 2 millimeters, and the disclosure is not limited to a rib structure that elevates a PEIO body to any particular height. -
PEIO 16 may be placed on a surface that is subject to occasional standing water such as, e.g., a golf course, an outdoor concert venue, or the like. In these applications, the electrical integrity ofPEIO 16 may be compromised ifPEIO 16 is immersed in the standing water. For this reason,shelter 10 may include at least one elevating portion that can elevate PEIO 16 above the surface on which the shelter is placed. Should water thereafter accumulate on the surface, the elevating portion of the shelter may preventPEIO 16 from being immersed in water. - In the example of
FIG. 2 ,shelter 10 includes fourlegs 41A-41C (only three of which are labeled for clarity and which are collectively referred to as “legs 41”) that function to elevateshelter 10 above a surface on which theshelter 10 is placed. Legs 41 extend downwardly (i.e., in the negative Z-direction) fromplatform 34 ofbase 12, and each leg of legs 41 is arranged adjacent a different corner ofplatform 34. Each leg of legs 41 is substantially the same height (i.e., in the Z-direction) such that legs 41 elevateplatform 34 and maintainplatform 34 in a generally parallel relationship with a surface on whichshelter 10 is set. - While
shelter 10 is illustrated as including four elevating legs 41, in different examples,shelter 10 may include more elevating portions (e.g., five or more legs), fewer elevating portions (e.g., three or less legs), or a different arrangement of elevating portions. For instance, in one example,shelter 10 may include three legs arranged in a tripod arrangement. In another example,shelter 10 may two legs arranged on opposing side ofbase 12. In yet another example,shelter 10 may include a single elevating portion centered about raisedrib structure 39 and extending downwardly fromplatform 34. It should be appreciated that the foregoing description of elevating portions are merely examples, and the disclosure is not limited to a shelter that includes any particular number or arrangement of elevating portions. Rather, any suitable feature or combination of features that function to elevateshelter 10 above a surface on which the shelter set may be used in accordance with the disclosure. - In some examples, the at least one elevating portion of
shelter 10 may be configured to support a threshold amount of weight. For example, in different configurations, the at least one elevating portion ofshelter 10 may support at least 50 pounds such as, e.g., at least 100 pounds, or at least 200 pounds. In the event that someone would stand on top of shelter 10 (e.g., whencover 14 is mated with base 12), the shelter may support that person's weight without breaking. - Independent of the specific arrangement of the at least one elevating portion of
shelter 10, in some examples, the at least one elevating portion ofshelter 10 may elevateplatform 34 at least 3 inches above a surface on which the shelter is set. Whenplatform 34 and, correspondinglyPEIO body 18, is elevated at least 3 inches above a surface on which the shelter is set, the likelihood thatPEIO body 18 will be immersed in standing water on the surface may be reduced or eliminated. For example, depending on the specific configuration ofshelter 10 andPEIO 16, whenplatform 34 is elevated at least 3 inches above a surface on which the shelter is set, electrical connects toPEIO body 18 may be elevated at least 4 inches above a surface on which the shelter is set, further increasing the separation distance between the electrical contacts and any surface water that may accumulate. - In different examples, the at least one elevating portion of
shelter 10 may elevateplatform 34 more than 3 inches above a surface on which the shelter is set (e.g., at least 6 inches, at least 8 inches), or less than 3 inches above a surface on which the shelter is set (e.g., approximately 1 inch, approximately 2 inches), and the disclosure is not limited in this respect. For instance, in some examples,shelter 10 includes an adjustable at least one elevating portion (e.g., adjustable legs) that can be extended to a plurality of different heights depending on the specific application forshelter 10. Alternatively,shelter 10 can be set on a separate base if additional height is desired beyond the height of a fixed-height elevating portion. - When
shelter 10 is configured withsidewall 36 as shown inFIG. 2 , water may accumulate withinbase 12. To remove water frombase 12,shelter 10 may include a drain aperture that allows accumulated water to flow out ofbase 12. The drain aperture may be separate from any cable apertures defined inshelter 10 so that water does not flow along the length of an electrical cable when flowing out ofbase 12. - In some examples,
shelter 10 may include a drain aperture that is defined insidewall 36 ofbase 12. In other examples,shelter 10 may include a drain aperture defined inplatform 34 ofbase 12. For example, as illustrated inFIG. 2 , each leg of legs 41 defines a lumen that is connected to a drain aperture 43 (only one of which is labeled for clarity) extending throughplatform 34. Should any water accumulate onplatform 34, the water may flow through drain aperture 43 (which is also identified onFIG. 1 for ease of reference), though a lumen defined by one of legs 41, and out the bottom of the leg and onto the surface on whichshelter 10 is set. In this manner, water may exitshelter 10 without substantially contacting electrical connections between PEIO body 18 (FIG. 1 ) and one or more of the cables electrically connected toPEIO body 18. - In some examples, at least a portion of
platform 34 may be sloped towarddrain aperture 43 to preferentially direct any water that may accumulate onplatform 34 out ofshelter 10. For example,platform 34 may be domed or peaked adjacent raisedrib structure 39 so that whenPEIO body 18 is placed on raisedrib structure 39, water preferentially flows away from raisedrib structure 39 towarddrain aperture 43. In another example, as illustrated inFIG. 2 , aregion 45 ofplatform 34 that is directly adjacent to drainaperture 43 may be sloped towarddrain aperture 43. In still other examples,platform 34 can be sloped in a different configuration than as illustrated inFIG. 2 . The different configurations may be dictated by the shape ofshelter 10, the configuration of an elevating portion ofshelter 10, or different considerations including, e.g., the shape ofPEIO body 18, which may be positioned inshelter 10. - As described above with respect to
FIG. 1 ,shelter 10 may include a variety of different apertures that define openings for physically and/or electrically connectingPEIO body 18 to features located outside ofshelter 10. Further,PEIO 16 in the example ofFIG. 1 includes PEIO-component connectors 24 that are configured to be electrically connected to an electrical component located outside ofshelter 10. For this reason,shelter 10 may include one or more apertures that define openings to extendcomponent cable 30 from PEIO-component connectors 24 disposed within an interior ofshelter 10 to an exterior ofshelter 10. - In the example of
FIG. 2 ,shelter 10 defines at least one PEIO-component-connector-cable hole, which inFIG. 2 is illustrated as four PEIO-component-connector-cable holes 80A-D (collectively “PEIO-component-connector-cable holes 80”). The PEIO-component-connector-cable holes 80 define openings that allow component cables to extend between a PEIO body positioned withinshelter 10 and an electrical component located outside ofshelter 10. For instance, during setup, PEIO body 18 (FIG. 1 ) may be positioned onplatform 34.Component cable 30 can be introduced (e.g., from either the bottom or top of base 12) through one of PEIO-component-connector-cable holes 80 and connected to one of PEIO-component connectors 24. When arranged according to this example process,component cable 30 will be connected to one of PEIO-component connectors 24 and will extend through one of PEIO-component-connector-cable holes 80 to an exterior ofshelter 10. - The number, size, and arrangement of PEIO-component-connector-cable holes 80 may vary, e.g., based on the specific configuration of
shelter 10 and the specific configuration ofPEIO 16. With respect to the example ofFIG. 2 , however, PEIO-component-connector-cable holes 80 are defined inplatform 34 ofbase 12. Specifically, two PEIO-component-connector-cable holes first portion 82 ofplatform 34, and two different PEIO-component-connector-cable holes second portion 84 ofplatform 34, where thefirst portion 82 ofplatform 34 is separated fromsecond portion 84 ofplatform 34 by raisedrib structure 39. Such a configuration may allow component cables to be connected to PEIO-component connectors 24 on PEIO 16 (FIG. 1 ), which includes two, outwardly-facing, side-by-side PEIO-component connectors arranged on one side ofPEIO body 18 and two different, outwardly-facing, side-by-side PEIO component connectors arranged on an opposing side ofPEIO body 18. That being said, in different examples, PEIO-component-connector-cable holes 80 may be defined withinsidewall 36 ofbase 12, withincover 14 ofshelter 10, or yet another location ofshelter 10. -
Shelter 10 may include one or more features to adjust the dimensions of PEIO-component-connector-cable holes 80 (e.g., to increase or decrease the diameter of the holes). In some examples, each PEIO-component-connector-cable hole 80 may be adjusted after inserting a component cable through the hole until there is substantially no separation gap between the component cable and the PEIO-component-connector-cable hole. A smaller separation gap between a PEIO-component-connector-cable hole and a component cable may decrease the likelihood that unwanted elements (e.g., rain, snow) may enter an interior ofshelter 10 through the separation gap. - In the example of
FIG. 2 , each PEIO-component-connector-cable hole is covered by a PEIO-component-connector-cable-hole cover 86 (only one of which is labeled for clarity). In use, PEIO-component-connector-cable-hole cover 86 can move between a first position in which a PEIO-component-connector-cable hole is open and a second position in which the PEIO-component-connector-cable hole is substantially closed. For example, with reference toFIG. 2 , an operator can slide PEIO-component-connector-cable-hole cover 86 in the X-Y plane to an open position, extend component cable 30 (FIG. 1 ) from an interior ofshelter 10 to an exterior ofshelter 10, and slide PEIO-component-connector-cable-hole cover 86 in an opposing direction in the X-Y plane to a substantially closed position. - In a different example, PEIO-component-connector-cable-
hole cover 86 may be hingedly mounted tobase 12 instead of mounted to slide between an open and a closed position. A hingedly mounted PEIO-component-connector-cable-hole cover may rotate between an open position and a substantially closed position (e.g., in the Y-Z plane) to allowcomponent cable 30 to be extended between an interior ofshelter 10 and an exterior ofshelter 10. Other configurations of PEIO-component-connector-cable-hole cover 86 are possible. - Independent of the specific arrangement of PEIO-component-connector-cable-
hole cover 86, PEIO-component-connector-cable-hole cover 86 may define a cutout 88 (FIG. 2 ) that corresponds to a size and/or shape ofcomponent cable 30.Cutout 88 may help preventcomponent cable 30 from being compressed when PEIO-component-connector-cable-hole cover 86 is moved to a substantially closed position. In some examples, the portion of PEIO-component-connector-cable-hole cover 86 that definescutout 88 may be positioned overplatform 34 when PEIO-component-connector-cable-hole cover 86 is closed and there is no component cable extending through the PEIO-component-connector-cable hole. For example, inFIG. 2 , the portion of PEIO-component-connector-cable-hole cover 86 that definescutout 88 may slide beyond PEIO-component-connector-cable hole 80A (i.e., to the left of the illustration in the Y-direction) when moved in a closed position. This arrangement may prevent water or debris from enteringshelter 10 when PEIO-component-connector-cable-hole cover 86 is closed and there is no component cable extending throughcutout 88. - Upon placing PEIO body 18 (
FIG. 1 ) onbase 12 and positioning cover 14 overbase 12, it may be useful to physically connectcover 14 tobase 12, e.g., to form an integral assembly that resists detachment except with user assistance. Physically attachingcover 14 tobase 12 may preventPEIO body 18 from inadvertently coming out ofshelter 10 during use or transport. For instance, in the example ofFIGS. 1 and 2 , cover 14 ofshelter 10 includes a cover-latch member 51, andbase 12 includes a complementary base-latch member 49. As shown, base-latch member 49 is a pair of protrusions that extend outwardly fromsidewall 36 ofbase 12. Also as shown, cover-latch member 51 is a protrusion that extends outwardly (e.g., in the X-Y plane) from cover-sidewall 42 and that defines a pair of holes that are configured to receive the protrusions defined by base-latch member 49. -
Cover 14 latches tobase 12 when cover-latch member 51 is engaged with base-latch member 49 (e.g., when the protrusions oflatch member 49 are inserted into the holes of latch member 51). When engaged,latch members cover 14 from detaching frombase 12 until, e.g., a user applies sufficient force to overcome the resistance of the latch members. In different examples, different latch members may be used in addition to, or in lieu of,latch members latch member 51 is included on thebase 12, and a latch member like base-latch member 49 is included on thecover 14. Additional examples of latch members may include, but are not limited to, screws, bolts, claps, or the like. - In some situations, it may be useful to lock
cover 14 tobase 12 in addition to or in lieu of frictionally latching the two components together. Lockingcover 14 tobase 12 may prevent a passerby from accessing PEIO 16 (FIG. 1 ) after the PEIO is locked inshelter 10. In the example ofFIG. 2 , cover 14 is locked to base 12 on one side byhinge 38. On the opposing side ofhinge 38, cover 14 includes cover-lockingapertures apertures cover 14 mates withbase 12, cover-lockingapertures apertures cover 14 andbase 12. A locking member can be inserted through one or both of the locking apertures to lockcover 14 andbase 12 together. Example locking members may include padlocks, zip ties, and the like. In this manner, cover 14 can be locked tobase 12. - As briefly discussed above with respect to
FIG. 1 ,shelter 10 may include an adjustable first PEIO-cable hole 44A and/or an adjustable second PEIO-cable hole 44B. In some examples, an adjustable cable hole may be adjusted (e.g., by increasing or decreasing the diameter of the cable hole) until there is substantially no separation gap between a PEIO cable and a PEIO cable hole when a PEIO cable is inserted intoshelter 10. A smaller separation gap between a PEIO cable and a PEIO-cable hole may decrease the likelihood that unwanted elements (e.g., rain, snow) may enter an interior ofshelter 10 through the separation gap. -
Shelter 10 can include any suitable feature that is capable of adjusting (e.g., increasing or decreasing) the dimensions of first PEIO-cable hole 44A and/or second PEIO-cable hole 44B.FIG. 3A shows an example of second base-PEIO-cablepartial hole 46B, which was described above with respect toFIG. 1 . In the example ofFIG. 3A , base-PEIO-cable partial-support 50B defines a plurality of different sizes (i.e., diameters) at different distances away from away from sidewall 36 (i.e., in the X-direction). Specifically, base-PEIO-cable partial-support 50B defines afirst portion 54 that extends from directlyadjacent sidewall 36 to afirst distance 57 away fromsidewall 36.First portion 54 of base-PEIO-cable partial-support 50B defines a first size. Base-PEIO-cable partial-support 50B also asecond portion 52 that extends fromfirst portion 54.Second portion 52 of base-PEIO-cable partial-support 50B defines a second size less than the first size. - Cover-PEIO-cable partial-
support 151B (illustrated onFIG. 1 ) defines a plurality of different complementary sizes (i.e., diameters) at different distances away from cover-sidewall 42, such that different sized PEIO-cable openings are defined at different distances away from cover-sidewall 42. Accordingly, whencover 14 is mated withbase 12, cover-PEIO-cable partial-support 151B and base-PEIO-cable partial-support 50B define a first sized opening at a first distance (i.e., in the X-direction) away fromshelter 10 and a second sized opening at a second distance (again, in the X-direction) away fromshelter 10. The first sized opening is larger than the second sized opening. - In examples in which
PEIO 16 includes a comparatively smallsecond PEIO cable 22, the cable can be inserted through the first and second sized openings defined, together, by cover-PEIO-cable partial-support 151B and base-PEIO-cable partial-support 50B so that the separation gap between the cable and the openings is defined as the difference between the cross-sectional size (e.g., in the Y-Z plane) of the cable and the cross-sectional size of the smaller second opening. By contrast, in examples in whichPEIO 16 includes a comparatively largersecond PEIO cable 22, the portions of cover-PEIO-cable partial-support 151B and base-PEIO-cable partial-support 50B that define the second smaller opening can be removed, e.g., by cutting or breaking the portion, so that the cable opening is defined by the larger first sized opening. In this manner,shelter 10 can be configured with an adjustable PEIO-cable hole. - In some examples, cover-PEIO-cable partial-
support 151B and base-PEIO-cable partial-support 50B may include a weakened portion betweenfirst portion 54 and second portion 52 (e.g., at weakened portion atdistance 57 onFIG. 3A ). A weakened portion may allow the second portion of the PEIO-cable hole to fracture from the first portion (e.g., upon application of hand pressure) without substantially affecting the length or diameter of the first portion. -
FIG. 3B shows another example of second PEIO-cable hole 44B with adjustable dimensions in accordance with the disclosure. In the example ofFIG. 3B , base-PEIO-cable partial-support 50B and cover-PEIO-cable partial-support 151B define a plurality of different sizes (i.e., diameters) at different distances away from away fromsidewall 36 and cover-sidewall 42, respectively. Specifically, base-PEIO-cable partial-support 50B and cover-PEIO-cable partial-support 151B each define afirst portion 160 that extends from directlyadjacent sidewall 36 and cover-sidewall 42, asecond portion 162 that extends fromfirst portion 160, and athird portion 164 that extends fromsecond portion 162.First portion 160 defines a first size,second portion 162 defines a second size less than the first size, andthird portion 164 defines a third size less than the second size. In use, a cable can be inserted through the first, second, and third sized openings defined by cover-PEIO-cable partial-support 151B and base-PEIO-cable partial-support 50B so that the separation gap between the cable and the openings is defined as the difference between the cross-sectional size of the cable and the cross-sectional size of the smallest (i.e., the third) opening. Alternatively, one or more portion of base-PEIO-cable partial-support 50B and cover-PEIO-cable partial-support 151B can be removed to define larger sized cable openings. - As illustrated in
FIG. 3B , cover-PEIO-cable partial-support 151B may include lip 17 (described above with reference toFIG. 1 ) that extends over base-PEIO-cable partial-support 50B whencover 14 is mated to base 12.Lip 17 may prevent water flowing off ofcover 14 from enteringshelter 10 at the junction betweencover 14 andbase 12. - While the forgoing description of
FIGS. 3A and 3B of an adjustable PEIO-cable hole was generally described with respect to second PEIO-cable hole 44B, it should be appreciated that PEIO-cable hole 44A ofshelter 10, or yet another aperture defined inshelter 10, may be configured with one or more of the described features. - As previously described,
shelter 10 in the example ofFIG. 1 includeshinge 38.Hinge 38 connectsbase 12 to cover 14 so thatcover 14 can pivotally rotate relative tobase 12.FIGS. 4A and 4B are exploded views of one example type of hinge that shelter 10 may use. In particular,FIG. 4A is an exploded view of anexample hinge section 100 affixed to cover-sidewall 42 ofcover 14, whileFIG. 4B is an exploded view of correspondingexample hinge section 102 affixed to sidewall 36 ofbase 12. As will be described,hinge section 100 ofFIG. 4A is configured to receivehinge section 102 ofFIG. 4B to createhinge 38.FIG. 5 is a conceptual illustration ofhinge 38 after assembly. - When configured as shown in
FIG. 4B ,hinge section 102 includes at least one support structure, which in the example ofFIG. 4B is illustrated as foursupport structures 104A-104C (collectively “support structures 104”), that connecthinge pin 106 to sidewall 36 ofbase 12. Support structures 104 permanently affixhinge pin 106 to sidewall 36 and alignhinge pin 106 parallel tosidewall 36.Hinge pin 106 defines afirst end projection 108 projecting fromsupport structure 104A (i.e., in the X-direction) and asecond end projection 110 projection fromsupport structure 104D (i.e., in the X-direction opposite first end projection 108).Hinge pin 106 and first andsecond end projections hinge pin 106 can be inserted into hinge section 100 (FIG. 4A ) to assemblehinge 38. - Hinge section 100 (
FIG. 4A ) defines at least one hinge pin receptacle for receivinghinge pin 106 during assembly, which, in the example configuration ofFIG. 4A , is a plurality of hinge pin receptacles.Hinge section 100 includes a first hinge pin receptacle-support structure 112 and a second hinge pin receptacle-support structure 114. First hinge pin receptacle-support structure 112 defines a firstprojection receptacle opening 116. Second hinge pin receptacle-support structure 114 defines a secondprojection receptacle opening 118.Hinge section 100 also includes at least a third hinge pin receptacle interposed between first hinge pin receptacle-support structure 112 and second hinge pin receptacle-support structure 114, which in the example ofFIG. 4A is illustrated as three additional hinge pin receptacle-support structures 120A-120C (collectively “support structures 120”). - First and second hinge pin receptacle-
support structures 112 and 114 extend first and secondprojection receptacle openings sidewall 42. Further, first and second hinge pin receptacle-support structures 112 and 114 each orient first and secondprojection receptacle openings FIG. 4A . First hinge pin receptacle-support structure 112 is configured to receivefirst end projection 108 of hinge pin 106 (FIG. 4B ) during assembly ofhinge 38. Second hinge pin receptacle-support structure 114 is configured to receivesecond end projection 110 of hinge pin 106 (FIG. 4B ) during assembly ofhinge 38. - Hinge pin receptacle-support structures 120 define receptacle openings that open in the positive Z-direction indicated on
FIG. 4A (i.e., in an opposite direction than first and secondprojection receptacle openings 116 and 118). Hinge pin receptacle-support structures 120 are configured to receive a portion of hinge pin 106 (FIG. 4B ) extending betweenfirst end projection 108 andsecond end projection 110 ofhinge pin 106 during assembly ofhinge 38. - During assembly,
hinge section 102 can be inserted in negative Z-direction indicated onFIG. 4A intohinge section 100 to createhinge 38. Specifically, first andsecond end projections hinge pin 106 can be inserted into first and secondprojection receptacle openings hinge pin 106 extending betweenfirst end projection 108 andsecond end projection 110 can be inserted into receptacle opening defined by hinge pin receptacle-support structures 120. Because first and secondprojection receptacle openings hinge pin 106 can be supported by opposing forces, which may preventhinge section 100 from separating fromhinge section 102. - Unlike hinge assemblies that require separate parts (e.g., a removable hinge pin) or tools to assemble, the
example hinge 38 described with respect toFIGS. 4A and 4B may not require separate parts or tools to assemble. Instead, the pin and receptacle features ofhinge 38 are permanently affixed tobase 12 andcover 14, respectively, and can be inserted into one another without specialized tools. In applications whereshelter 10 is assembled in the field, such an example hinge may save time and expense associated with complicated or laborious assembly. - In some examples, hinge 38 may include one or more features to assist assembly. For instance, in the example of
FIG. 4A , first and second hinge pin receptacle-support structures 112 and 114 include assembly guides 122A and 122B, respectively. Assembly guides 122A and 122B define corresponding channels that taper (e.g., in the X and/or Y-directions) in the negative Z-direction. First andsecond end projections FIG. 4B ) can be inserted into assembly guides 122A and 122B, respectively, during assembly ofhinge 38. As first andsecond end projections support structures 112 and 114 to be displaced in opposing directions (i.e., in opposing X-directions). In this manner, first andsecond end projections support structures 112 and 114 and into first and secondprojection receptacle openings - While
hinge 38 was described as being configured withhinge section 100 affixed to cover-sidewall 42 ofcover 14 andhinge section 102 affixed to sidewall 36 ofbase 12, it should be appreciated that in other examples,hinge section 100 can be affixed to sidewall 36 ofbase 12 andhinge section 102 can be affixed to cover-sidewall 42 ofcover 14. Other configurations and arrangements of the various features ofhinge 38 are contemplated. - In some examples, hinge 38 is configured so that
cover 14 can pivotally rotate at least 180 degrees relative tobase 12 between an open position and a closed position. Such a configuration may provide ready access toplatform 34 ofbase 12, e.g., for inserting and removingPEIO 16 fromshelter 10. - A shelter in accordance with the disclosure can assume a variety of different configurations, as described above. In some examples, a shelter according to the disclosure may be configured to be stacked in a nested arrangement with a plurality of similarly configured shelters. When configured to be stacked in a nested arrangement, multiple shelters may be stored and/or transported within a confined space.
-
FIG. 6 is a conceptual drawing of an example stacked arrangement forshelters 10A-10E. Each shelter ofshelters 10A-10E may define the configuration ofshelter 10, described above with respect toFIGS. 1-5 . As seen in the example ofFIG. 6 , covers 14A-14E ofshelters 10A-10E are rotated open approximately 180 degrees relative tobases 12A-12E. Further the base of one shelter (e.g., 12 A) is inserted into the base of another shelter (e.g., 12B), while the cover of one shelter (e.g., 14A) is inserted into the cover of another shelter (e.g., 14B). In this manner, each shelter ofshelters 10A-10E is stacked on top of one another to define a nested stack of shelters. In some examples, this configuration of shelters may allow multiple shelters to be stored and/or transported within a confined space. -
FIGS. 7-13 illustrate several different views of an example shelter that includes features illustrated and described with respect to shelter 10 above.FIG. 7 is perspective view of the example shelter.FIG. 8 is a perspective top view of the example shelter ofFIG. 7 .FIG. 9 is a perspective bottom view of the example shelter ofFIG. 7 .FIG. 10 is a perspective side view of the example shelter ofFIG. 7 .FIG. 11 is a perspective view of an example portion of the example shelter ofFIG. 7 .FIG. 12 is a perspective view of an example hinge on the example shelter ofFIG. 7 .FIG. 13 is another perspective side view of the example shelter ofFIG. 7 . - In the foregoing detailed description, the invention has been described with reference to specific examples. However, it may be appreciated that various modifications and changes can be made without departing from the scope of the invention as set forth in the appended claims. Thus, some of the features of preferred embodiments described herein are not necessarily included in preferred embodiments of the invention which are intended for alternative uses.
