Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] 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.
TECHNICAL FIELD
[0002] This disclosure relates to electrical connectors and, more
particularly, to shelters for electrical connectors.
BACKGROUND
[0003] 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.
[0004] 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.
[0005] 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.
SUMMARY
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.

DETAILED DESCRIPTION
[0025] The following detailed description is exemplary in nature
and is not intended to limit the scope, applicability, or
configuration of the invention in any way. 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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
to FIG. 1.
[0030] FIG. 1 is conceptual view of an example shelter 10 in
accordance with this disclosure. Shelter 10 includes base 12 and
cover 14. Base 12 is configured to support PEIO 16. PEIO 16 can be
positioned onto base 12, and cover 14 can be positioned over base
12 to substantially encase PEIO 16 within shelter 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 otherwise short circuit PEIO 16. In one
example, shelter 10 includes a rib structure (FIG. 2) that is
configured to segregate PEIO 16 from water that may accumulate in a
main area of base 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 which shelter 10
is set. Shelter 10 may include additional or different features, as
described below.
[0031] Shelter 10 is configured to support PEIO 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 of FIG. 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.
[0032] Because PEIO 16 is generally illustrated in the style of a
quad box in FIG. 1, the remainder of the present disclosure
generally refers to an example configuration of shelter 10 that is
designed to receive a quad box. However, other configurations of
shelter 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).
[0033] In the example of FIG. 1, which generally depicts a quad
box-style PEIO, PEIO 16 includes a PEIO body 18, a first PEIO cable
20, a second PEIO cable 22, and at least one PEIO-component
connector 24, which in the example of FIG. 1 is illustrated as four
PEIO-component connectors (collectively "connectors 24," only one
of which is labeled for clarity). First PEIO cable 20 electrically
connects PEIO 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 connect PEIO body 18 to a power
source (e.g., without any intervening components) or indirectly
connect PEIO body 18 to a power source (e.g., through another PEIO
body). Second PEIO cable 22 electrically connects PEIO 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 of PEIO 16, first PEIO cable 20 and second PEIO cable
22 may each be permanently attached to PEIO body 18, or one or both
of first PEIO cable 20 and second PEIO cable 22 may be detachable
from PEIO body 18. For example, as seen in FIG. 1, first PEIO cable
20 and second PEIO cable 22 may be detachably connected to PEIO
body 18 via threaded connectors 26A and 26B, respectively, although
any suitable mechanical fixation element (e.g., clasp, bolt, screw)
may be used to detachably connect first PEIO cable 20 and second
PEIO cable 22 to PEIO body 18. For instance, PEIO body 18 may
include male electrical connectors (e.g., two or three-prong
electrical connectors) and first PEIO cable 20 and/or second PEIO
cable 22 may include corresponding female electrical connectors
which can be friction fit over the male connectors of PEIO body
18.
[0034] First PEIO cable 20 and second 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 and second PEIO cable 22 can carry single-phase
alternating current (AC), three-phase AC, or direct current (DC).
In some examples, first PEIO cable 20 and second 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 and second 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 and second
PEIO cable 22 are each configured to electrically convey less than
or equal to approximately 600 volts.
[0035] 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 of FIG. 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 a component 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).
[0036] 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 of PEIO body 18 and two different, outwardly-facing,
side-by-side PEIO component connectors arranged on an opposing side
of PEIO 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 in FIG.
1.
[0037] As seen in the example FIG. 1, in some applications, each
PEIO-component connector or each set of PEIO-component connectors
of PEIO 16 may include a cover 32 that rotates relative to PEIO
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.
[0038] Each PEIO-component connector of PEIO 16 may be electrically
connected to a component cable, such as component cable 30. In
general, component cable 30 is an electrically conductive cable
that includes an electrically insulative exterior. Depending on the
configuration of PEIO 16, component cable 30 may be a standard
extension cord that plugs in to PEIO body 18 at one of
PEIO-component connectors 24 and that extends to a component that
operates on electrical energy, or component cable 30 may be
non-standard cable that is capable of conducting electrical
energy.
[0039] In operation, PEIO 16 can distribute power from a power
supply to one or more electrically connected components. In one
example, power enters PEIO body 18 via first PEIO cable 20 and is
split between each PEIO-component connectors of PEIO-component
connectors 24 and second 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 entering PEIO 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 and second PEIO cable 22. PEIO 16 may
have other configurations as well.
[0040] To help protect PEIO 16 from unwanted elements, PEIO 16 may
be positioned in shelter 10 in accordance with this disclosure.
Shelter 10 can assume different configurations; however, in the
example of FIG. 1, shelter 10 includes base 12 and cover 14. Base
12 includes platform 34 and sidewall 36. Platform 34 provides
physical support for PEIO body 18 when PEIO 16 is inserted into
shelter 10. Sidewall 36 extends substantially around the perimeter
of platform 34 to define a cavity that is configured to receive
PEIO 16. Cover 14 is configured to mate with base 12 to
substantially enclose platform 34. Specifically, in the example of
FIG. 1, cover 14 is pivotally mounted to base 12 via hinge 38 and
is configured to mate with an upper surface of sidewall 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 of
base 12. In FIG. 1, PEIO 16 can be inserted into base 12, and cover
14 can close over PEIO body 18 to help protect PEIO body 18 within
a bounded cavity defined by platform 34, sidewall 36, and cover 14.
By positioning PEIO body 18 between base 12 and cover 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
to FIG. 2, shelter 10 may include various features to help prevent
PEIO body 18 from being exposed to moisture during operation.
[0041] As shown in FIG. 1, shelter 10 receives PEIO 16 by
positioning PEIO body 18 on platform 34. Platform 34 physically
supports PEIO body 18 within shelter 10. Platform 34 may define any
suitable size and shape, and the size and shape of platform 34 may
vary, e.g., based on the size and shape of PEIO body 18. For
example, platform 34 may define a planar surface or a non-planar
surface, as described in greater detail below with respect to FIG.
2. In some examples, PEIO 16 mechanically attaches to platform 34,
e.g., by mechanically attaching a bottom surface of PEIO body 18 to
platform 34. For instance, a mechanical fixation element such as,
e.g., bolts, screws, adhesive, or the like may be used to
mechanically attach PEIO 16 to platform 34. In other examples, PEIO
16 is supported on platform 34 without being mechanically affixed
to platform 34. For instance, in the example shown in FIG. 1, PEIO
16 is positioned on platform 34 and cover 14 may rotate closed over
PEIO 16 to friction fit PEIO 16 between base 12 and cover 14. Such
an arrangement may prevent PEIO 16 from moving out of alignment
with base 12 after PEIO 16 is positioned within shelter 10.
[0042] In the example of FIG. 1, base 12 includes at least one
sidewall 36, which is illustrated as four interconnected sidewalls
that surround a substantially rectangular-shaped platform 34.
Sidewall 36 extends upwardly (i.e., in the Z-direction indicated on
FIG. 1) from platform 34. Sidewall 36 may help protect the sides of
PEIO body 18 from unintended contact and may also define a surface
that can mate with cover 14. In some examples, as illustrated in
FIG. 1, sidewall 36 extends around substantially the entire
perimeter of platform 34 (i.e., in the X-Y plane indicated on FIG.
1). In other examples, sidewall 36 extends around less than the
entire perimeter of platform 34. For example, base 12 may include a
plurality of discrete sidewall segments that are physically
separated from one another around platform 34. In yet other
examples, base 12 may not include sidewall 36. In such an example,
PEIO 16 may be positioned on platform 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 with base 12 around
a perimeter of platform 34.
[0043] 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 of base 12 may
vary, e.g., based on the specific shape of PEIO 16.
[0044] In operation, base 12 of shelter 10 may be placed on a
surface that is exposed to unwanted elements from above (i.e., in
the Z-direction indicated on FIG. 1) such as, e.g., rain, snow, or
inadvertent contact. For this reason, shelter 10 may include a
cover that mates with base 12 to help protect PEIO 16 from above.
Shelter 10 may include any suitable cover including, e.g., a cover
that mates with base 12 such that there is substantially no
separation gap between the cover and base 12. Such a cover may
prevent unwanted elements from entering shelter 10 from the sides
of the shelter (i.e., in the X-Y plane).
[0045] In the example of FIG. 1, cover 14 includes top 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 on FIG. 1) from top
surface 40. Top surface 40 may be planar as illustrated in FIG. 1
or non-planar (e.g., domed, peaked, or the like). A non-planar top
surface 40 may help repel unwanted elements from top surface 40 and
may help prevent water or debris from collecting on top surface
40.
[0046] As with sidewall 36 of base 12, cover-sidewall 42 may help
protect the sides of PEIO body 18 from unintended contact when PEIO
16 is inserted into shelter 10. In some examples, as illustrated in
FIG. 1, cover-sidewall 42 extends around substantially the entire
perimeter of top surface 40 (i.e., in the X-Y plane indicated on
FIG. 1). Cover 14 may define a size and shape that substantially
corresponds to a size and shape of base 12. In such an example,
cover 14 may mate with base 12 when an edge of cover-sidewall 42 is
positioned adjacent an edge of sidewall 36 of base 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 of cover 14 may be positioned directly adjacent base 12
to encase PEIO 16 within shelter 10.
[0047] In some examples, cover 14 may include a lip that extends
over an edge of base 12 when cover 14 is mated to base 12. For
instance, in the example of FIG. 1, cover 14 includes lip 17 (also
illustrated in FIG. 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. When cover 14 is mated with base 12, lip
17 extends down over sidewall 36 of base 12 so that any rain that
falls on cover 14 flows off cover-sidewall 42 without entering
shelter 10 at the junction between cover 14 and base 12.
[0048] As discussed above with respect to base 12, cover 14 can
define shapes other than the substantially rectangular shape
illustrated in FIG. 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 of cover 14 may vary, e.g., based on the
specific shape of PEIO 16 and/or the specific shape of base 12.
[0049] The specific dimensions of shelter 10 may vary, e.g., based
on the specific dimensions of PEIO 16. That being said, in some
examples, shelter 10 may include cover 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
include base 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.
[0050] 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 protect PEIO 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 for shelter 10 are both possible and
contemplated.
[0051] As described above, PEIO 16 includes first PEIO cable 20 and
second PEIO cable 22. When PEIO body 18 is positioned within
shelter 10, first PEIO cable 20 and second PEIO cable 22 may
electrically connect PEIO body 18 to components located outside of
shelter 10. For this reason, shelter 10 may include one or more
apertures that define openings for physically and/or electrically
connecting PEIO body 18 to features located outside of shelter 10.
The number and arrangement of the different apertures may vary,
e.g., based on the specific configuration of shelter 10 and the
specific configuration of PEIO 16. However, with respect to the
example of FIG. 1, shelter 10 defines a first PEIO-cable hole 44A
and a second PEIO-cable hole 44B (which in FIG. 1 are denoted by
labeled double-headed arrows, indicating that first PEIO-cable hole
44A and second PEIO-cable hole 44B are defined when cover 14 is
mated to base 12). First PEIO-cable hole 44A is configured (e.g.,
sized and shaped) to permit first PEIO cable 20 to extend from PEIO
body 18 to an exterior of shelter 10, while second PEIO-cable hole
44B is configured (e.g., sized and shaped) to permit second PEIO
cable 22 to extend from PEIO body 18 to an exterior of shelter
10.
[0052] First PEIO-cable hole 44A and second PEIO-cable hole 44B can
be arranged at any suitable location on shelter 10. In different
examples, first PEIO-cable hole 44A and/or second PEIO-cable hole
44B may be defined entirely by base 12 of shelter 10, entirely by
cover 14 of shelter 10, or in yet another location of shelter 10.
For instance, in the example of FIG. 1, first PEIO-cable hole 44A
and second PEIO-cable hole 44B are located at an interface between
base 12 and cover 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-cable partial 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-cable partial hole 48B are lesser
portions of first PEIO-cable hole 44A and second PEIO-cable hole
44B, respectively. When cover 14 is mated with base 12 (e.g.,
brought into adjacent alignment) first base-PEIO-cable partial hole
46A aligns with first cover-PEIO-cable partial hole 48A to create
first PEIO-cable hole 44A, while second base-PEIO-cable partial
hole 46B aligns with second cover-PEIO-cable partial hole 48B to
create second PEIO-cable hole 44B. With this arrangement, first
PEIO cable 20 and second PEIO cable 22 can extend from PEIO body 18
to an exterior of shelter 10 through first PEIO-cable holes 44A and
44B, respectively. Moreover, first PEIO cable 20 and second PEIO
cable 22 may be friction fit between base 12 and cover 14 in such
an arrangement, which may prevent PEIO 16 from moving out of
alignment with respect to base 12 after PEIO 16 is positioned
within shelter 10.
[0053] 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 to FIGS. 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 and shelter 10 than a non-adjustable
cable hole, which may reduce the ingress of unwanted elements into
shelter 10 through the cable hole.
[0054] 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 support first PEIO cable 20 and/or second
PEIO cable 22, respectively. FIG. 1 illustrates an example of
shelter 10 that includes example support surfaces.
[0055] In the example of FIG. 1, shelter 10 includes
base-PEIO-cable partial-support 50A and 50B (collectively "supports
50") that extend substantially orthogonally from sidewall 36 of
base 12. Base-PEIO-cable partial-supports 50 are aligned with first
and second base-PEIO-cable partial-holes 46A and 46B, respectively.
First PEIO cable 20 and second PEIO cable 22 can extend through
first and second base-PEIO-cable partial-holes 46A and 46B,
respectively, and be supported by base-PEIO-cable partial-supports
50 in the region of base 12 adjacent sidewall 36.
[0056] When configured as shown in FIG. 1, cover 14 includes
complementary cover-PEIO-cable partial-supports 151A and 151B
(collectively "supports 151") that extends substantially
orthogonally from cover-sidewall 42 and that are aligned with first
and second cover-PEIO-cable partial-holes 48A and 48B,
respectively. When cover 14 is mated with base 12, cover-PEIO-cable
partial-supports 151A and 151B align with base-PEIO-cable
partial-supports 50A and 50B. As a result, when first PEIO cable 20
is extended through first PEIO-cable hole 44A and second PEIO cable
22 is arranged through second PEIO-cable hole 44B, first and second
PEIO cables 20 and 22 are supported in the negative Z-direction
(i.e., downwardly) by base-PEIO-cable partial-support 50A and 50B
and in the positive Z-direction (i.e., upwardly) by a
cover-PEIO-cable partial-supports 151A and 151B. Such support may
help reduce or eliminate cable chafing or cracking in the region
adjacent cable connectors 26A and 26B over the service life of PEIO
16.
[0057] While shelter 10 in the example of FIG. 1 includes support
surfaces on both base 12 and cover 14, it should be appreciated
that in other examples according to the disclosure, a shelter may
include support surfaces that extend only from base 12 or extend
only from cover 14. The arrangement and location of support
surfaces in these examples may be dictated by the arrangement and
location of PEIO-cable holes 44A and 44B on the shelter.
[0058] 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. When PEIO 16 is
exposed to moisture from inclement weather, the moisture may cause
short circuits that reduce the electrical integrity of PEIO 16. To
reduce or eliminate water accumulation adjacent PEIO 16 in these
applications, shelter 10 may include moisture management
features.
[0059] FIG. 2 is a conceptual illustration of one example of
shelter 10, generally described above with respect to FIG. 1, which
includes example moisture management features. In FIG. 2, like
reference numerals between FIGS. 1 and 2 refer to like elements.
Further, for ease of description, PEIO 16 is not illustrated within
shelter 10 in the example of FIG. 2.
[0060] In the example of FIG. 2, platform 34 of shelter 10 includes
a main area 37 and a raised rib structure 39. Raised rib structure
39 may segregate PEIO 16 (FIG. 1) from moisture that may accumulate
on main area 37. Raised rib structure 39 extends upwardly (i.e., in
the Z-direction) from main area 37 of platform 34. Accordingly,
PEIO body 18 (FIG. 1) can be positioned on raised rib structure to
elevate PEIO body 18 above main area 37 of platform 34. Should
water accumulate on main area 37 of shelter 10, raised rib
structure 39 can segregate PEIO body 18 from the accumulated water,
which may reduce or eliminate the possibility of a short circuit
between PEIO body 18 and component cable 30.
[0061] Depending on the configuration of shelter 10, raised rib
structure 39 may be a single rib (i.e., a single elevating feature
that functions to elevate PEIO body 18 above main area 37), or a
plurality of rib features. For instance, in the example of FIG. 2,
raised rib 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 of rib
structure 39 are both possible and contemplated.
[0062] Independent of the specific configuration of rib structure
39, in some examples, rib structure 39 may elevate PEIO body 18 at
least 2 millimeters above main area 37. When PEIO body 18 is
elevated at least 2 millimeters above main area 37, the likelihood
that PEIO body 18 will be immersed in water within shelter 10 may
be reduced or eliminated. It should be appreciated though that rib
structure 39 may elevate PEIO 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.
[0063] 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 of PEIO 16 may be compromised if PEIO 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
prevent PEIO 16 from being immersed in water.
[0064] In the example of FIG. 2, shelter 10 includes four legs
41A-41C (only three of which are labeled for clarity and which are
collectively referred to as "legs 41") that function to elevate
shelter 10 above a surface on which the shelter 10 is placed. Legs
41 extend downwardly (i.e., in the negative Z-direction) from
platform 34 of base 12, and each leg of legs 41 is arranged
adjacent a different corner of platform 34. Each leg of legs 41 is
substantially the same height (i.e., in the Z-direction) such that
legs 41 elevate platform 34 and maintain platform 34 in a generally
parallel relationship with a surface on which shelter 10 is
set.
[0065] 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 of base
12. In yet another example, shelter 10 may include a single
elevating portion centered about raised rib structure 39 and
extending downwardly from platform 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 elevate shelter 10 above a surface on which the
shelter set may be used in accordance with the disclosure.
[0066] 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 of shelter 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., when cover 14
is mated with base 12), the shelter may support that person's
weight without breaking.
[0067] Independent of the specific arrangement of the at least one
elevating portion of shelter 10, in some examples, the at least one
elevating portion of shelter 10 may elevate platform 34 at least 3
inches above a surface on which the shelter is set. When platform
34 and, correspondingly PEIO body 18, is elevated at least 3 inches
above a surface on which the shelter is set, the likelihood that
PEIO body 18 will be immersed in standing water on the surface may
be reduced or eliminated. For example, depending on the specific
configuration of shelter 10 and PEIO 16, when platform 34 is
elevated at least 3 inches above a surface on which the shelter is
set, electrical connects to PEIO 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.
[0068] In different examples, the at least one elevating portion of
shelter 10 may elevate platform 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 for shelter 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.
[0069] When shelter 10 is configured with sidewall 36 as shown in
FIG. 2, water may accumulate within base 12. To remove water from
base 12, shelter 10 may include a drain aperture that allows
accumulated water to flow out of base 12. The drain aperture may be
separate from any cable apertures defined in shelter 10 so that
water does not flow along the length of an electrical cable when
flowing out of base 12.
[0070] In some examples, shelter 10 may include a drain aperture
that is defined in sidewall 36 of base 12. In other examples,
shelter 10 may include a drain aperture defined in platform 34 of
base 12. For example, as illustrated in FIG. 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 through platform 34.
Should any water accumulate on platform 34, the water may flow
through drain aperture 43 (which is also identified on FIG. 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 which shelter 10
is set. In this manner, water may exit shelter 10 without
substantially contacting electrical connections between PEIO body
18 (FIG. 1) and one or more of the cables electrically connected to
PEIO body 18.
[0071] In some examples, at least a portion of platform 34 may be
sloped toward drain aperture 43 to preferentially direct any water
that may accumulate on platform 34 out of shelter 10. For example,
platform 34 may be domed or peaked adjacent raised rib structure 39
so that when PEIO body 18 is placed on raised rib structure 39,
water preferentially flows away from raised rib structure 39 toward
drain aperture 43. In another example, as illustrated in FIG. 2, a
region 45 of platform 34 that is directly adjacent to drain
aperture 43 may be sloped toward drain aperture 43. In still other
examples, platform 34 can be sloped in a different configuration
than as illustrated in FIG. 2. The different configurations may be
dictated by the shape of shelter 10, the configuration of an
elevating portion of shelter 10, or different considerations
including, e.g., the shape of PEIO body 18, which may be positioned
in shelter 10.
[0072] 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 connecting PEIO body 18 to features
located outside of shelter 10. Further, PEIO 16 in the example of
FIG. 1 includes PEIO-component connectors 24 that are configured to
be electrically connected to an electrical component located
outside of shelter 10. For this reason, shelter 10 may include one
or more apertures that define openings to extend component cable 30
from PEIO-component connectors 24 disposed within an interior of
shelter 10 to an exterior of shelter 10.
[0073] In the example of FIG. 2, shelter 10 defines at least one
PEIO-component-connector-cable hole, which in FIG. 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 within
shelter 10 and an electrical component located outside of shelter
10. For instance, during setup, PEIO body 18 (FIG. 1) may be
positioned on platform 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 of shelter
10.
[0074] 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 of PEIO 16. With respect to the example of FIG. 2,
however, PEIO-component-connector-cable holes 80 are defined in
platform 34 of base 12. Specifically, two
PEIO-component-connector-cable holes 80A and 80B are defined in a
first portion 82 of platform 34, and two different
PEIO-component-connector-cable holes 80C and 80D are defined in a
second portion 84 of platform 34, where the first portion 82 of
platform 34 is separated from second portion 84 of platform 34 by
raised rib 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 of PEIO body 18 and
two different, outwardly-facing, side-by-side PEIO component
connectors arranged on an opposing side of PEIO body 18. That being
said, in different examples, PEIO-component-connector-cable holes
80 may be defined within sidewall 36 of base 12, within cover 14 of
shelter 10, or yet another location of shelter 10.
[0075] 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 of shelter 10 through the separation
gap.
[0076] 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 to FIG. 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 of shelter 10 to an exterior of shelter 10, and slide
PEIO-component-connector-cable-hole cover 86 in an opposing
direction in the X-Y plane to a substantially closed position.
[0077] In a different example, 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.
[0078] 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 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. For example, in FIG. 2, the
portion of PEIO-component-connector-cable-hole cover 86 that
defines cutout 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 entering shelter 10 when
PEIO-component-connector-cable-hole cover 86 is closed and there is
no component cable extending through cutout 88.
[0079] Upon placing PEIO body 18 (FIG. 1) on base 12 and
positioning cover 14 over base 12, it may be useful to physically
connect cover 14 to base 12, e.g., to form an integral assembly
that resists detachment except with user assistance. Physically
attaching cover 14 to base 12 may prevent PEIO body 18 from
inadvertently coming out of shelter 10 during use or transport. For
instance, in the example of FIGS. 1 and 2, cover 14 of shelter 10
includes a cover-latch member 51, and base 12 includes a
complementary base-latch member 49. As shown, base-latch member 49
is a pair of protrusions that extend outwardly from sidewall 36 of
base 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.
[0080] Cover 14 latches to base 12 when cover-latch member 51 is
engaged with base-latch member 49 (e.g., when the protrusions of
latch member 49 are inserted into the holes of latch member 51).
When engaged, latch members 49 and 51 may prevent cover 14 from
detaching from base 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 49 and 51. In one example, a latch member
like cover-latch member 51 is included on the base 12, and a latch
member like base-latch member 49 is included on the cover 14.
Additional examples of latch members may include, but are not
limited to, screws, bolts, claps, or the like.
[0081] In some situations, it may be useful to lock cover 14 to
base 12 in addition to or in lieu of frictionally latching the two
components together. Locking cover 14 to base 12 may prevent a
passerby from accessing PEIO 16 (FIG. 1) after the PEIO is locked
in shelter 10. In the example of FIG. 2, cover 14 is locked to base
12 on one side by hinge 38. On the opposing side of hinge 38, cover
14 includes cover-locking apertures 53A and 53B, and base includes
base-locking apertures 55A and 55B. When cover 14 mates with base
12, cover-locking apertures 53A and 53B align with base-locking
apertures 55A and 55B to define two locking apertures extending
through cover 14 and base 12. A locking member can be inserted
through one or both of the locking apertures to lock cover 14 and
base 12 together. Example locking members may include padlocks, zip
ties, and the like. In this manner, cover 14 can be locked to base
12.
[0082] 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 into shelter 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 of shelter 10 through the separation gap.
[0083] 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-cable partial hole 46B,
which was described above with respect to FIG. 1. In the example of
FIG. 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 a first portion 54 that
extends from directly adjacent sidewall 36 to a first distance 57
away from sidewall 36. First portion 54 of base-PEIO-cable
partial-support 50B defines a first size. Base-PEIO-cable
partial-support 50B also a second portion 52 that extends from
first portion 54. Second portion 52 of base-PEIO-cable
partial-support 50B defines a second size less than the first
size.
[0084] Cover-PEIO-cable partial-support 151B (illustrated on FIG.
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, when cover 14
is mated with base 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 from shelter 10
and a second sized opening at a second distance (again, in the
X-direction) away from shelter 10. The first sized opening is
larger than the second sized opening.
[0085] In examples in which PEIO 16 includes a comparatively small
second 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 which PEIO 16
includes a comparatively larger second 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.
[0086] In some examples, cover-PEIO-cable partial-support 151B and
base-PEIO-cable partial-support 50B may include a weakened portion
between first portion 54 and second portion 52 (e.g., at weakened
portion at distance 57 on FIG. 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.
[0087] FIG. 3B shows another example of second PEIO-cable hole 44B
with adjustable dimensions in accordance with the disclosure. In
the example of FIG. 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 from sidewall 36 and cover-sidewall 42, respectively.
Specifically, base-PEIO-cable partial-support 50B and
cover-PEIO-cable partial-support 151B each define a first portion
160 that extends from directly adjacent sidewall 36 and
cover-sidewall 42, a second portion 162 that extends from first
portion 160, and a third portion 164 that extends from second
portion 162. First portion 160 defines a first size, second portion
162 defines a second size less than the first size, and third
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.
[0088] As illustrated in FIG. 3B, cover-PEIO-cable partial-support
151B may include lip 17 (described above with reference to FIG. 1)
that extends over base-PEIO-cable partial-support 50B when cover 14
is mated to base 12. Lip 17 may prevent water flowing off of cover
14 from entering shelter 10 at the junction between cover 14 and
base 12.
[0089] 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 of shelter 10, or yet another aperture defined
in shelter 10, may be configured with one or more of the described
features.
[0090] As previously described, shelter 10 in the example of FIG. 1
includes hinge 38. Hinge 38 connects base 12 to cover 14 so that
cover 14 can pivotally rotate relative to base 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 an example hinge
section 100 affixed to cover-sidewall 42 of cover 14, while FIG. 4B
is an exploded view of corresponding example hinge section 102
affixed to sidewall 36 of base 12. As will be described, hinge
section 100 of FIG. 4A is configured to receive hinge section 102
of FIG. 4B to create hinge 38. FIG. 5 is a conceptual illustration
of hinge 38 after assembly.
[0091] When configured as shown in FIG. 4B, hinge section 102
includes at least one support structure, which in the example of
FIG. 4B is illustrated as four support structures 104A-104C
(collectively "support structures 104"), that connect hinge pin 106
to sidewall 36 of base 12. 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 104A (i.e., in the X-direction)
and a second end projection 110 projection from support structure
104D (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.
[0092] Hinge section 100 (FIG. 4A) defines at least one hinge pin
receptacle for receiving hinge pin 106 during assembly, which, in
the example configuration of FIG. 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 first projection
receptacle opening 116. Second hinge pin receptacle-support
structure 114 defines a second projection 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 of FIG. 4A is illustrated as three
additional hinge pin receptacle-support structures 120A-120C
(collectively "support structures 120").
[0093] First and second hinge pin receptacle-support structures 112
and 114 extend first and second projection receptacle openings 116
and 118, respectively, away from cover-sidewall 42. Further, first
and second hinge pin receptacle-support structures 112 and 114 each
orient first and second projection receptacle openings 116 and 118,
respectively, in the negative Z-direction indicated on FIG. 4A.
First hinge pin receptacle-support structure 112 is configured to
receive first end projection 108 of hinge pin 106 (FIG. 4B) during
assembly of hinge 38. Second hinge pin receptacle-support structure
114 is configured to receive second end projection 110 of hinge pin
106 (FIG. 4B) during assembly of hinge 38.
[0094] 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 second
projection receptacle openings 116 and 118). Hinge pin
receptacle-support structures 120 are configured to receive a
portion of hinge pin 106 (FIG. 4B) extending between first end
projection 108 and second end projection 110 of hinge pin 106
during assembly of hinge 38.
[0095] During assembly, hinge section 102 can be inserted in
negative Z-direction indicated on FIG. 4A into hinge section 100 to
create hinge 38. Specifically, first and second end projections 108
and 110 of hinge pin 106 can be inserted into first and second
projection receptacle openings 116 and 118, respectively, while the
portion of hinge pin 106 extending between first end projection 108
and second end projection 110 can be inserted into receptacle
opening defined by hinge pin receptacle-support structures 120.
Because first and second projection receptacle openings 116 and 118
open in one direction while receptacle opening defined by hinge pin
receptacle-support structures 120 open in an opposite direction,
hinge pin 106 can be supported by opposing forces, which may
prevent hinge section 100 from separating from hinge section
102.
[0096] Unlike hinge assemblies that require separate parts (e.g., a
removable hinge pin) or tools to assemble, the example hinge 38
described with respect to FIGS. 4A and 4B may not require separate
parts or tools to assemble. Instead, the pin and receptacle
features of hinge 38 are permanently affixed to base 12 and cover
14, respectively, and can be inserted into one another without
specialized tools. In applications where shelter 10 is assembled in
the field, such an example hinge may save time and expense
associated with complicated or laborious assembly.
[0097] 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 and second end projections 108 and 110 of hinge pin 106 (FIG.
4B) can be inserted into assembly guides 122A and 122B,
respectively, during assembly of hinge 38. As first and second end
projections 108 and 110 are pressed in the negative Z-direction,
the tapering on assembly guides 122A and 122 may cause first and
second hinge pin receptacle-support structures 112 and 114 to be
displaced in opposing directions (i.e., in opposing X-directions).
In this manner, first and second end projections 108 and 110 can be
inserted between first and second hinge pin receptacle-support
structures 112 and 114 and into first and second projection
receptacle openings 116 and 118, respectively.
[0098] While hinge 38 was described as being configured with hinge
section 100 affixed to cover-sidewall 42 of cover 14 and hinge
section 102 affixed to sidewall 36 of base 12, it should be
appreciated that in other examples, hinge section 100 can be
affixed to sidewall 36 of base 12 and hinge section 102 can be
affixed to cover-sidewall 42 of cover 14. Other configurations and
arrangements of the various features of hinge 38 are
contemplated.
[0099] In some examples, hinge 38 is configured so that cover 14
can pivotally rotate at least 180 degrees relative to base 12
between an open position and a closed position. Such a
configuration may provide ready access to platform 34 of base 12,
e.g., for inserting and removing PEIO 16 from shelter 10.
[0100] 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.
[0101] FIG. 6 is a conceptual drawing of an example stacked
arrangement for shelters 10A-10E. Each shelter of shelters 10A-10E
may define the configuration of shelter 10, described above with
respect to FIGS. 1-5. As seen in the example of FIG. 6, covers
14A-14E of shelters 10A-10E are rotated open approximately 180
degrees relative to bases 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 of shelters 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.
[0102] 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 of FIG. 7. FIG. 9 is a perspective bottom view of the
example shelter of FIG. 7. FIG. 10 is a perspective side view of
the example shelter of FIG. 7. FIG. 11 is a perspective view of an
example portion of the example shelter of FIG. 7. FIG. 12 is a
perspective view of an example hinge on the example shelter of FIG.
7. FIG. 13 is another perspective side view of the example shelter
of FIG. 7.
[0103] 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.
