It will be understood that any one of the walls  240 ,  244 ,  248 ,  250 ,  252  of the second housing  176  may define the opening  260  and may be coupled to the sleeve  264  with the wall selection being based on the positioning of the door closure assembly  10  within the door assembly  74 ,  76 . It will further be understood that the latch assembly  28  may be in connection with the outer door  16  directly without the second housing  176  without departing from the scope of the present disclosure. 
     Referring now to  FIGS. 5 and 6 , according to various examples, the base  30  may be positioned within the second housing  176 . The base  30  may have a primary wall  276  configured to be aligned with the sidewall  248  of the second housing  176 . A foot  280  may be positioned on each end of the primary wall  276 . Each foot  280  may extend perpendicularly to the primary wall  276 , such that each foot  280  is aligned with and parallel to one of the top wall  250  and the bottom wall  252 . According to various examples, the base  30  may be sized to fit within the second housing  176 , such that the primary wall  276  is substantially flush with the sidewall  248  of the second housing  176  and each foot  280  is substantially flush with one of the top wall  250  and the bottom wall  252 , respectively. In other examples, the base  30  may be positioned within the second housing  176 , such that the primary wall  276  is offset from the sidewall  248  and divides the second housing  176 . 
     At least one fastener  284  may be used to couple each foot  280  of the base  30  to the respective top or bottom wall  250 ,  252 . It will be understood that the base  30  may be integrally formed with the second housing  176  or may be coupled to the second housing  176  using other methods, such as, for example, adhesive or welding. It will also be understood that the sidewall  248  of the second housing  176  may act as the base  30  where the sidewall  248  forms the primary wall  276  and the top and bottom walls  250 ,  252  are each foot  280 , respectively. It is also contemplated that the base  30  may be operably coupled with the outer door  16  without the second housing  176  without departing from the scope of the present disclosure. 
     Referring still to  FIGS. 5 and 6 , the first and second cams  32 ,  40  are pivotally coupled to the primary wall  276  of the base  30 . The first cam  32  includes an upper edge  290  integrally formed with a raised edge  294 . The upper edge  290  may be generally arcuate or curved and may be concave relative to the top of the first cam  32 . The upper edge  290  includes the first contact surface  34  of the first cam  32 . The first contact surface  34  may be positioned substantially perpendicular to the primary wall  276 . The first contact surface  34  is positioned proximate to the second cam  40  and may be configured to engage with the second contact surface  44  of the second cam  40 , as discussed elsewhere herein. 
     The raised edge  294  is further integrally formed with a side edge  298 . In some examples, the raised edge  294  may be inclined away from the upper edge  290  and toward the side edge  298 . The side edge  298  may extend linearly from the raised edge  294 . The upper edge  290 , the raised edge  294 , and the side edge  298  may extend partially about a periphery of a primary portion  304  of the first cam  32 . The primary portion  304  of the first cam  32  may define a pivot aperture  308  configured to receive a pivot pin  312 . The pivot pin  312  may further be coupled to the primary wall  276  of the base  30 , such that the first cam  32  is rotatable between an inclined position ( FIG. 7 ) and a neutral position ( FIG. 8 ). 
     A first protrusion  300  extends from the side edge  298  and may be integrally formed with the primary portion  304  of the first cam  32 . The first protrusion  300  defines a first connection aperture  320 . According to various examples, the first connection aperture  320  is defined at a first side of the first protrusion  300  and may be configured to engage with a connection end  324  of an actuation member  328 . The actuation member  328  extends through the sleeve  264  operably coupled to the bottom wall  252  of the second housing  176  and through the opening  260  defined by the bottom wall  252  of the second housing  176 . It will be understood that the actuation member  328  may be a rod, cable, or any other member capable of translating force. It will also be understood that the connection end  324  of the actuation member  328  may be a hook, loop, or any other connection configured to be received by or coupled to the connection aperture  320  and/or the second cam  40 . For examples, a pin  332  may be positioned through the connection aperture  320 , such that the pin  332  extends outward from and perpendicular to the protrusion  300 . The connection end  324  of the actuation member  328  may be a loop or hook configured to receive the pin  332  and couple the actuation member  328  with the second cam  40 . In other examples, the connection end  324  may extend perpendicularly to the actuation member  328 , such that the connection end  324  is received by the connection aperture  320 . 
     The first protrusion  300  of the first cam  32  may also define a second connection aperture  336  positioned proximate the first connection aperture  320 . The second connection aperture  336  may be positioned on a second side of the first protrusion  300  opposite the first connection aperture  320 . The second connection aperture  336  may be configured to receive a first end  340  of a coiled spring  344 . The spring  344  may be a helical spring and may extend between the first cam  32  and the second cam  40 . The spring  344  may be operable between a released state ( FIG. 7 ) and a loaded state ( FIG. 8 ). The released and loaded states of the spring  344  may be configured to correspond to inclined and neutral positions of the first cam  32 . The released and loaded states of the spring  344  may further be configured to correspond to unlocked and locked positions of the second cam  40 . 
     Referring still to  FIGS. 5 and 6 , the second cam  40  includes a primary portion  368 . The primary portion  368  of the second cam  40  may define a pivot aperture  376  configured to receive a pivot pin  380 . The pivot pin  380  may further be coupled to the primary wall  276 , such that the second cam  40  is rotatable between an unlocked position ( FIG. 7 ) and a locked position ( FIG. 8 ). 
     The primary portion  368  of the second cam  40  may include a first lower edge  350  integrally formed with a second lower edge  352 . The first and second lower edges  350 ,  352  may be generally arcuate or curved. Each of the first and second lower edges  350 ,  352  may be generally convex relative to the bottom of the second cam  40 . The first lower edge  350  may be separated from the second lower edge  352  by a step. Together, the first and second lower edges  350 ,  352  of the second cam  40  may define the second contact surface  44 . The second contact surface  44  includes a first portion  356  and a second portion  360 . The first portion  356  of the second contact surface  44  extends along the first lower edge  350 . Similarly, the second portion  360  of the second contact surface  44  extends along the second lower edge  352 . Each of the first and second portions  356 ,  360  of the second contact surface  44  may be integrally formed with the step. 
     A second protrusion  364  extends from and may be integrally formed with the primary portion  368  of the second cam  40 . The second protrusion  364  may extend in substantially the same direction as the first protrusion  300  relative to the second housing  176  and/or the primary wall  276 . The second protrusion  364  may define a third connection aperture  370 . The third connection aperture  370  may be configured to receive a second end  372  of the spring  344 . The spring  344  extends between the first protrusion  300  of the first cam  32  and the second protrusion  364  of the second cam  40 . The spring  344  couples the first cam  32  and the second cam  40 . The coupling of the spring  344  to the third connection aperture  370  may be configured to correspond the unlocked and locked positions of the second cam  40  with the unloaded and loaded states of the spring  344 . Subsequently, the unlocked and locked positions of the second cam  40  may correspond with the inclined and neutral positions of the first cam  32 , as discussed elsewhere herein. 
     Referring now to  FIGS. 5-8 , a hook  390  may extend from the primary portion  368  of the second cam  40 . The latch hook  390  may be oriented proximate the pivot aperture  376  and the pivot pin  380  of the second cam  40 . The hook  390  may further be positioned opposite the second protrusion  364  of the second cam  40 . According to various examples, the hook  390  may be generally arcuate or curved relative to the primary portion  368  of the second cam  40 . In other examples, the hook  390  may extend linearly from the primary portion  368  of the second cam  40 . The hook  390  may be shaped and positioned, such that the hook  390  extends through the retention space  24  of the anchor  20  when the second cam  40  is in the locked position ( FIG. 8 ). 
     Referring now to  FIGS. 4 and 6 , the actuation member  328  may extend the length of the sleeve  264 . A second end  392  of the actuation member  328  may extend outward from a second open end  394  of the sleeve  264  opposite the first open end  268  of the sleeve  264 . The second end  392  of the actuation member may be coupled to a lever  398 . The lever  398  may include a handle  400  and a connection end  404 . The handle  400  and connection end  404  may be rotatable about a pivot  408 . According to various examples, the lever  398  may be positioned within one of the pocket handles  160 , such that the handle  400  of the lever  398  is substantially concealed within the cavity  164  of the pocket handle  160 . 
     Referring now to  FIG. 4 , the lever  398  may be rotated about the pivot  408  when a user applies pressure to the handle  400  of the lever  398  in the direction of arrow A. When the lever  398  is rotated about the pivot  408 , the connection end  404  may rotate, applying tension to the actuation member  328  by pulling the second end  392  of the actuation member  328  downward along arrow B. The tension along the actuation member  328  may be translated into a pulling force along arrow B acting on the first protrusion  300  of the first cam  32 . 
     Referring now to  FIGS. 5-8 , and as discussed elsewhere herein, the latch assembly  28  is shown in the first position with the spring  344  in the unloaded state, the first cam  32  in the inclined position, and the second cam in the unlocked position ( FIG. 7 ) and the second position with the spring  344  in the loaded state, the first cam in the neutral position, and the second cam in the locked position ( FIG. 8 ). When the tension generated by the rotation of the lever  398  is translated through the actuation number  328  and into force on protrusion  300  of the first cam  32 , the first cam  32  is rotated in a clockwise direction about the pivot pin  312  as viewed from the side profile of  FIGS. 7 and 8 . The rotation of the first cam  32  moves the first cam  32 , such that the raised edge  294  and part of the first contact surface  34  abut the second protrusion  364  and the second portion  360  of the second contact surface  44 , respectively. This contact between the first cam  32  and the second cam  40  positions the first cam  32  to support the second cam  40  in the unlocked position. The proximity of the first and second protrusions  300 ,  364  removes stress from the spring  344  and allows the spring  344  to remain in the unloaded state. The spring  344  may further be biased into the unloaded state, biasing the second cam  40  into the unlocked position when the first cam  32  is in the inclined position. The bias of the spring  344  may provide tension to hold the second cam  40  in the unlocked position. The latch assembly  28  is configured to remain in the first position absent force applied to push the second cam  40  into the locked position. 
     When the outer door  16  is moved from the open position to the closed position, the connection portion  214  of the anchor  20  may be at least partially received by the latch opening  256  of second housing  176 . When the connection portion  214  is received by the second housing  176 , a front edge  402  of the connection portion  214  may be configured to contact a front edge  406  of the second cam  40 . As the outer door  16  is moved into the closed position, the front edge  402  of the connection portion  214  applies force to the front edge  406  of the second cam  40 . The force pushes the primary portion  368  of the second cam  40  toward the front wall  244  of the second housing  176 . The force from the front edge  402  of the connection portion  214  of the anchor  20  causes the second cam  40  to rotate counter-clockwise about the pivot pin  380  as viewed from the side profile of  FIGS. 7 and 8 . The rotation of the second cam  40  applies force opposite the bias of the spring  344 , moving the spring  344  into the loaded state. The second cam  40  is rotated about the pivot pin  380  until the first portion  356  of the second contact surface  44  abuts the first contact surface  34  of the first cam  32 . The raised edge  294  of the first cam  32  may be positioned to abut the step between the first and second lower edges  350 ,  352  of the second cam  40 . 
     When the first and second contact surface  34 ,  44  are engaged, as shown in  FIG. 8 , the latch assembly  28  is in the second position. When the latch assembly  28  is in the second position, the hook  390  of the second cam  40  may be engaged with the retention space  24  of the connection portion  214  of the anchor  20 . The hook  390  may be positioned, such that the hook  390  extends through the retention space  24  of the anchor  20 , coupling the latch assembly  28  with the anchor assembly  170 . The latch assembly  28  is configured to remain in the second position absent force applied to the lever  398  to rotate the first cam  32  into the inclined position. 
     Referring now to  FIGS. 9 and 10 , in various examples, the inner door  14  and the outer door  16  of the door assembly  74  may be secured using a magnetic force as opposed to a latch. Where a magnetic force is used, the first and second hinge assemblies  150 ,  154  may include a locking member  532  configured to prevent inadvertent release of the outer door  16  from the inner door  14  when the outer door  16  and the inner door  14  are being rotated from the closed position to the open position. It is contemplated that the locking member  532  and the door closure assembly  10  may be used concurrently or separately without departing from the scope of the present disclosure. It will also be understood that the refrigerated door assembly  74  shown is exemplary and that the locking member  532  and first and second hinge assemblies  150 ,  154  may be used on any door assembly  74 ,  76  of the appliance  50  ( FIG. 1 ). 
     The first hinge assembly  150  may include a first hinge plate  500  operably coupled with the cabinet  60  of the refrigerated appliance  50 . The first hinge plate  500  may include a first hinge arm  504  extending outward from the first hinge plate  500  and away from a front of the cabinet  60 . The first hinge arm  504  may be operably pivotally coupled to the inner door  14  of the door assembly  74  at a first pivot. A protrusion  508  may extend from the first hinge arm  504  opposite the first pivot and in line with the inner door  14 . 
     Similarly, the second hinge assembly  154  may include a second hinge plate  512  operably coupled with a top of the inner door  14 . The second hinge plate  512  may include a second hinge arm  516  extending from the second hinge plate  512  and along the outer door  16 . The second hinge arm  516  may be pivotally coupled to the outer door  16  of the door assembly  74  at a second pivot. The second pivot may be substantially aligned with the first pivot of the first hinge assembly  150 . 
     A pin  520  may extend from one of the second hinge plate  512  and the second hinge arm  516 . The pin  520  may be positioned proximate the front edge of the inner door  14 . The pin  520  may be configured to pivotally couple the locking member  532  with the second hinge assembly  154 . The pin  520  may be spaced apart from the protrusion  508  of the first hinge assembly  150  and the front edge of the outer door  16 . 
     A retention hook  524  may extend from the front edge of the outer door  16  and toward the inner door  14 . The retention hook  524  may be integrally formed with the outer door  16 . The retention hook  524  may include a lip extending perpendicular to the front edge of the outer door  16 , such that the retention hook  524  and the front edge of the outer door  16  may define a space  528 . The space  528  may be generally rectangular in shape, according to various examples. In other examples, the space  528  may be semi-circular, triangular, or any other shape. 
     The locking member  532  may include a body  534  defining an aperture configured to receive the pin  520 . According to various examples, the body  534  may be generally circular. In other examples, the body  534  may be oblong, triangular, square, rectangular, or any other shape. The locking member  532  may be configured to rotate about the pin  520  between a locked and an unlocked position. When the inner door  14  is in the closed position, the locking member  532  may be positioned in the unlocked position. When the inner door  14  is in the open position, the locking member  532  may be positioned in the locked position. 
     A first arm  536  may extend from a first portion of the body  534  of the locking member  532 . A second arm  540  may extend from a second portion of the body  534  of the locking member  532 . The first arm  536  and the second arm  540  may define an obtuse angle with a vertex at the center point of the aperture of the body  534  of the locking member  532 . The first arm  536  may be a first length configured to span from the pin  520  to the protrusion  508  of the first hinge assembly  150 . The first arm  536  may include a first end positioned proximate the protrusion  508  of the first hinge assembly  150 . Similarly, the second arm  540  may be a second length configured to span from the pin  520  to the outer edge of the outer door  16 . The second arm  540  may include a second end having a foot  544 . The foot  544  may be positioned substantially parallel with the outer edge of the outer door  16  and aligned with the space  528  defined by the retention hook  524 . 
     A spring  548  may be positioned over the pin  520  and coupled with the locking member  532 . The spring  548  is configured to bias the locking member  532  in the unlocked position. When the inner door  14  is in the closed position, the first end of the first arm  536  is positioned proximate to the protrusion  508  of the first hinge assembly  150 . When the inner door  14  begins to move from the closed position to the open position, the first end of the first arm  536  abuts the protrusion  508 . As the inner door  14  rotates along the first pivot of the first hinge assembly  150 , the contact between the first arm  536  and the protrusion  508  rotates the second arm  540  about the pin  520 . As the second arm  540  rotates, the foot  544  of the second arm  540  may be rotated into the space  528  and into engagement with the retention hook  524 . The engagement between the foot  544  and the retention hook  524  prevents inadvertent release of the outer door  16  when the inner door  14  is in the open position. This prevents the outer door  16  from swinging open if the inner door  14  is opened rapidly or with force. It also prevents the release of the outer door  16  if the inner door  14  is slammed. 
     Referring now to  FIGS. 11 and 12 , when a magnetic force is used to couple the inner door  14  and the outer door  16  of door assembly  74 ,  76  ( FIG. 1 ), a release lever  582  may be positioned within the pocket handle  160  to release the outer door  16  from the inner door  14 . It is contemplated that the release lever  582 , the locking member  532 , and/or the door closure assembly  10  may be used concurrently or separately without departing from the scope of the present disclosure. 
     The pocket handle  160  may include a housing  550  having a front wall  554  and a rear wall  556  spaced apart by sidewalls. The housing  550  may define a lever cavity  558  in communication with the cavity  164  of the pocket handle  160 . The rear wall  556  of the housing  550  may be positioned parallel to the outer panel  130  of the inner door  14  when the outer door  16  is in a closed position. The rear wall  556  may further define an opening  560  proximate the outer panel  130  of the inner door  14 . According to various examples, the opening  560  may be generally square. In other examples, the opening  560  may be circular, oblong, rectangular, or shaped like any other higher order polygon. 
     A release member  564  may be positioned in the cavity  558  and proximate the opening  560 . The release member  564  may include a first end  568  and a second end  570 . The first end  568  may be positioned within the cavity and may be configured to abut a top wall of the housing  550 . The first end  568  may extend parallel to the front wall  554  and the rear wall  556 . The first end  568  and the second end  570  may be integrally formed. In various examples, the first end  568  of the release member  564  and the second end  570  of the release member  564  may be joined at a corner. The corner may be oriented at a right angle, such that the second end  570  of the release member  564  is positioned perpendicular to the first end  568  of the release member  564 . 
     The second end  570  of the release member  564  may be aligned with the opening  560  of the rear wall  556  and may have a cross-sectional shape configured to complement the shape of the opening  560 . The second end  570  may further include a foot  574  extending from the second end  570 . The foot  574  may be positioned perpendicular to the second end  570  and parallel to the outer panel  130  of the inner door  14 . In various examples, the second end  570  may be positioned to extend at least partially through the opening  560  of the rear wall  556  of the housing  550 , such that the foot  574  is positioned proximate the outer panel  130  of the inner door  14 . In other examples, the second end  570  may be positioned to extend through the opening  560  of the rear wall  556  of the housing  550 , such that the foot  574  abuts the outer panel  130  of the inner door  14 . In still other examples, the second end  570  of the release member  564  may be positioned to extend into the opening  560 , such that the foot  574  is positioned substantially flush with the rear wall  556  of the housing  550 . 
     A spring  578  may be positioned between the rear wall  556  and the first end  568  of the release member  564 . The spring  578  may abut the rear wall  556  and the first end  568  of the release member  564  and may be compressible by the first end  568  of the release member  564 . The spring  578  may be configured to bias the release member  564  toward the front wall  554  of the housing  550 . 
     The lever  582  may be coupled to the sidewall of the housing  550  by a pivot pin  596 . The lever  582  may include a body  586  configured to receive the pivot pin  596 . A first arm  590  extends from a first end of the body  586 . The first arm  590  may extend upward from the body toward the top wall of the housing  550  and parallel to the first end  568  of the release member  564 . The first arm  590  of the lever  582  is configured to at least partially abut the first end  568  of the release member  564 . 
     A second arm  594  extends from a second end of the body  586 . The second arm  594  is positioned laterally opposing the first arm  590  of the lever  582  and extends downward toward the cavity  164  of the pocket handle  160 . The second arm  594  is positioned parallel to the front wall  554  of the housing  550 . The second arm  594  of the lever  582  may be accessible by a user to actuate the release member  564 , as discussed elsewhere herein. 
     The lever  582  may be rotatable about the pivot pin  596  between a first position ( FIG. 11 ) and a second position ( FIG. 12 ). A tension spring  600  may be coupled with the lever  582  and may be configured to bias the lever  582  in the first position. The tension spring  600  allows the lever  582  to rotate back into the first position after a user has applied pressure to the second arm  594  of the lever  582  to move the lever  582  into the second position. 
     A cover  604  may be positioned extending from the rear wall  556  of the housing  550  to the body  586  of the lever  582 . The cover  604  may extend along the second end  570  of the release member  564 , protecting the release member  564 . The cover  604  may further support the release member  564  and may be operably coupled with the sidewall and/or the rear wall  556  of the housing  550 . 
     The first position of the lever  582  may correspond with a neutral position of the release member  564 . Similarly, the second position of the lever  582  may correspond with an engaged position of the release member  564 . When a user applies force to the second end  570  of the lever  582 , the lever  582  rotates about the pivot pin  596 , such that the first arm  590  of the lever  582  is inclined rearward toward the rear wall  556  of the housing  550  and the second arm  594  of the lever  582  is inclined toward the front wall  554  of the housing  550  ( FIG. 12 ). The first arm  590  of the lever  582  abuts the first end  568  of the release member  564 , pushing the release member  564  from the neutral position into the engaged position. When the release member  564  moves to the engaged position, the foot  574  of the second end  570  of the release member  564  applies a force to the outer panel  130  of the inner door  14 . The force from the release member  564  may separate the outer door  16  from the inner door  14 , separating the inner door  14  and the outer door  16  so that the outer door  16  may be moved into the open position. 
     When the release member  564  is in a neutral position ( FIG. 11 ), the spring  578  may be in an unloaded state. When the release member  564  is moved from the neutral position ( FIG. 11 ) to the engaged position ( FIG. 12 ), the spring  578  is compressed between the first end  568  of the release member  564  and the rear wall  556  of the housing  550 , placing the spring  578  in a loaded state. In the loaded state, the spring  578  applies a force opposite the first arm  590  of the lever  582 . When the user stops applying force to the second arm  594  of the lever  582 , the tension spring  600  biases the lever  582  into the first position. When the lever  582  is biased into the first position, the spring  578  biases the release member  564  into the neutral position.

     It will be understood by one having ordinary skill in the art that construction of the described disclosure and other components is not limited to any specific material. Other exemplary examples of the disclosure disclosed herein may be formed from a wide variety of materials, unless described otherwise herein. 
     As used herein, the term “about” means that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. When the term “about” is used in describing a value or an end-point of a range, the disclosure should be understood to include the specific value or end-point referred to. Whether or not a numerical value or end-point of a range in the specification recites “about,” the numerical value or end-point of a range is intended to include two embodiments: one modified by “about,” and one not modified by “about.” It will be further understood that the end-points of each of the ranges are significant both in relation to the other end-point, and independently of the other end-point. 
     The terms “substantial,” “substantially,” and variations thereof as used herein are intended to note that a described feature is equal or approximately equal to a value or description. For example, a “substantially planar” surface is intended to denote a surface that is planar or approximately planar. Moreover, “substantially” is intended to denote that two values are equal or approximately equal. In some embodiments, “substantially” may denote values within about 10% of each other. 
     For purposes of this disclosure, the term “coupled” (in all of its forms, couple, coupling, coupled, etc.) generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional central members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature or may be removable or releasable in nature unless otherwise stated. 
     Furthermore, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected” or “operably coupled” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable” to each other to achieve the desired functionality. Some examples of operably couplable include, but are not limited to, physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components. Furthermore, it will be understood that a component preceding the term “of the” may be disposed at any practicable location (e.g., on, within, and/or externally disposed from the appliance) such that the component may function in any manner described herein. 
     It is also important to note that the construction and arrangement of the elements of the disclosure as shown in the exemplary examples is illustrative only. Although only a few examples of the present innovations have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited. For example, elements shown as integrally formed may be constructed of multiple parts or elements shown as multiple parts may be integrally formed, the operation of the interfaces may be reversed or otherwise varied, the length or width of the structures and/or members or connectors or other elements of the system may be varied, the nature or number of adjustment positions provided between the elements may be varied. It should be noted that the elements and/or assemblies of the system might be constructed from any of a wide variety of materials that provide sufficient strength or durability, in any of a wide variety of colors, textures, and combinations. Accordingly, all such modifications are intended to be included within the scope of the present innovations. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the desired and other exemplary examples without departing from the spirit of the present innovations. 
     It will be understood that any described processes or steps within described processes may be combined with other disclosed processes or steps to form structures within the scope of the present disclosure. The exemplary structures and processes disclosed herein are for illustrative purposes and are not to be construed as limiting. 
     It is also to be understood that variations and modifications can be made on the aforementioned structures and methods without departing from the concepts of the present disclosure, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
