Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of U.S. Provisional Application No. 62/354,959, flied on Jun. 27, 2016, which is hereby incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     Vehicles, such as golf carts, may be used to transport people and/or objects from one location to another. Some conventional golf carts include a roof mounted to a cart frame to protect its occupants from the environment. Conventional golf carts are side-door free to facilitate quick and convenient ingress into the cabin area and egress out of the cabin area. During inclement weather, however, the cabin area of such golf carts may be exposed to weather elements, such as cold temperatures, rain, and/or high winds. 
     At least some conventional golf carts include awnings, curtains, and/or enclosure panels connected to the frame and/or roof to provide protective covering for the cabin. Known tracks that couple such awnings, curtains, and/or enclosure panels to golf carts, however, are fastened to the frame and/or roof in a manner that may compromise the integrity of the frame and/or roof. Set screw fasteners, for example, extend through the frame and/or roof and may create weak points that lead to failure or corrosion. Furthermore, such set screw fasteners may present safety issues, as workers or users my cut themselves on the set screw fasteners. 
     SUMMARY 
     Examples of the disclosure enable an enclosure to be removably coupled to a roof of a golf cart. A track includes a retention section and an access section. The retention section includes a first linear sidewall, a second linear sidewall spaced from the first linear sidewall to define an enclosure channel therebetween, a first lip portion extending from a first end portion of the first linear sidewall generally toward the second linear sidewall, and a second lip portion extending from a second end portion of the second linear sidewall generally toward the first linear sidewall. The second lip portion is spaced from the first lip portion to define a slot therebetween. The slot is sized to retain an enclosure cord extending through the enclosure channel in the enclosure channel. The access section includes an open sidewall coupled to the first linear sidewall or the second linear sidewall. The access section is configured to provide access to a longitudinal end portion of the retention section for removably extending the enclosure cord through the enclosure channel. 
     In another aspect, a system is provided for fabricating a track. The system includes a die component, a removal component, and a bend component. The die component is configured to form a raw track. The die component includes a plurality of die walls arranged generally in a rectangular configuration and a first member extending substantially perpendicularly from a first die wall of the plurality of die walls. The first member includes a body portion having a first width and a stem portion having a second width less than the first width such that the die component is configured to form a first linear sidewall between the body portion and the second die wall, a second linear sidewall between the body portion and the third die wall, a first lip portion between the stem portion and the second die wall, and a second lip portion between the stem portion and the third die wall. The removal component is configured to locate an access section of the raw track and, from the access section, remove one of the first linear sidewall or the second linear sidewall. The bend component is configured to bend the access section. 
     In yet another aspect, a method is provided for fabricating a track configured to couple an enclosure to a roof of a golf cart. The method includes forming a first raw track including a first linear sidewall, a second linear sidewall spaced from the first linear sidewall to define an enclosure channel therebetween, a first lip portion extending from a first end portion of the first linear sidewall generally toward the second linear sidewall, and a second lip portion extending from a second end portion of the second linear sidewall generally toward the first linear sidewall. The second lip portion is spaced from the first lip portion to define a slot therebetween. The slot is sized to retain an enclosure cord extending through the enclosure channel in the enclosure channel. The method further includes locating one or more access sections of the first raw track, removing, from the one or more access sections, the first linear sidewall or the second linear sidewall, and bending the one or more access sections.

     DETAILED DESCRIPTION 
     The present disclosure relates to coupling mechanisms and, more particularly, to a track system that couples an enclosure to a roof of a vehicle. The examples described herein include a retention section configured to retain an enclosure cord and an access section configured to provide access to a longitudinal end portion of the retention section for inserting and/or removing the enclosure cord. The examples described herein allow a user to install a track and/or couple an enclosure to a vehicle in a convenient, efficient, safe, and/or economical manner. The examples described herein are lightweight and durable. The examples described herein include a variety of configurations, and the description and/or figures that utilize a golf cart are exemplary only. The examples described herein may be used with any open-sided vehicle, such as personal transport vehicles, tractors, all-terrain vehicles, lawn equipment, construction equipment, and/or farm equipment. 
       FIG. 1  shows an example golf cart  100 . The golf cart  100  includes a frame  110  and a roof  120  coupled to the frame  110 . The frame  110  and/or roof  120  define a cabin  130  in which one or more occupants may be seated and/or equipment may be stored. The cabin  130  is generally open to the ambient environment. An enclosure (shown in  FIG. 4 ) may be coupled to the golf cart  100  to at least partially enclose the cabin  130 . In this manner, the enclosure may be used to provide at least some protection for the occupants and/or equipment from the ambient environment. While  FIG. 1  shows a smaller (e.g., two person) golf cart, the systems and methods described herein may be used with any open-sided vehicle, including larger (e.g., four person, six person, eight person) golf carts. 
       FIG. 2  shows one or more example tracks  200  that may be used to couple an enclosure to a roof  120  of a golf cart  100  (shown in  FIG. 1 ). The track  200  may provide a lightweight yet durable framework for support and rigidity for the roof  120 . The track  200  may be fabricated from a variety of materials, such as an aluminum material. In some examples, the track  200  is fabricated from an extrudable material at a variety of lengths, widths, thicknesses, and/or shapes such that the track  200  may be mitered, punched, repaired, or otherwise processed to function as described herein. In some examples, a coupling mechanism  202  securely couples one or more tracks  200  to the roof  120  such that the tracks  200  are stationary or do not move relative to the golf cart  100 . Additionally or alternatively, the coupling mechanism  202  may securely couple a plurality of tracks  200  to the roof  120  such that the tracks  200  are stationary or do not move relative to each other. 
     In some examples, a first track  210  of the plurality of tracks  200  is coupled to the roof  120  such that the first track  210  at least partially circumscribes a body portion  212  of the roof  120 . For example, the first track  210  may extend generally about a periphery of the roof  120  along one or more edge portions  214  of the roof  120 , including one or more side edge portions  216  and/or one or more corner edge portions  218 . In some examples, the first track  210  includes one or more retention sections  222  extending generally along the side edge portions  216  and/or one or more access sections  224  extending generally along the corner edge portions  218 . In this manner, a first segment of an enclosure (shown in  FIG. 4 ) may extend along a retention section  222 , and a second segment of the enclosure may extend along an access section  224 . The retention sections  222  are configured to retain at least a portion of the enclosure for coupling the enclosure to the golf cart  100 , and the access sections  214  are configured to provide access to a longitudinal end portion  226  of an adjacent retention section  222 . Access may be provided to the longitudinal end portion  226  of a retention section  222 , for example, to selectively and/or removably couple the enclosure to the roof  120 . 
       FIG. 3  shows an example retention section  222  oriented such that an X-axis  300  defines a positive lateral (e.g., outward) direction  302  and a negative lateral (e.g., inward) direction  304 , a Y-axis  310  defines a positive vertical (e.g., upward) direction  312  and a negative vertical (e.g., downward) direction  314 , and a Z-axis  320  defines a positive longitudinal direction  322  and a negative longitudinal direction  324 .  FIG. 4  shows the retention section  222  coupling an enclosure  330  to a roof  120  of a golf cart  100  (shown in  FIG. 1 ). As shown in  FIG. 4 , the enclosure  330  includes an enclosure cord  332  and an enclosure panel  334  extending from the enclosure cord  332 . The enclosure panel  334  may extend generally downward (e.g., in the negative vertical direction  314 ) and/or hang from an enclosure cord  332  coupled to the roof  120 , for example, to at least partially enclose the cabin  130  (shown in  FIG. 1 ). 
     The retention section  222  includes a first linear sidewall  340  and a second linear sidewall  342  laterally spaced from the first linear sidewall  340  to define an enclosure channel  344  therebetween. For example, an inner sidewall (e.g., the first linear sidewall  340 ) may define one side area of the enclosure channel  344 , and/or an outer sidewall (e.g., the second linear sidewall  342 ) may define another side area of the enclosure channel  344 . The first linear sidewall  340  extends vertically and/or longitudinally generally parallel to the second linear sidewall  342 . As shown in  FIG. 4 , the enclosure channel  344  is sized to allow the enclosure cord  332  to extend therethrough. For example, the second linear sidewall  342  may be spaced from the first linear sidewall  340  a distance  346  (e.g., a first distance) greater than a width  348  of the enclosure cord  332  (e.g., a first width). In this manner, the enclosure cord  332  may be selectively and/or removably extended longitudinally through the enclosure channel  344 , between the first linear sidewall  340  and second linear sidewall  342 , from a longitudinal end portion  226  (shown in  FIG. 2 ) of the retention section  222 . 
     Additionally, the retention section  222  includes a first lip portion  350  extending laterally from a lower end portion  352  of the first linear sidewall  340  (e.g., a first end portion) and a second lip portion  354  extending laterally from a lower end portion  356  of the second linear sidewall  342  (e.g., a second end portion). The first lip portion  350  may extend generally toward the lower end portion  356  of the second linear sidewall  342 , and/or the second lip portion  354  may extend generally toward the lower end portion  352  of the first linear sidewall  340 , to partially define the enclosure channel  344 . For example, the first lip portion  350  and/or second lip portion  354  may define one or more shallow areas of the enclosure channel  344 . The first lip portion  350  is at the same or a substantially similar elevation or height as that of the second lip portion  354 . 
     The second lip portion  354  is spaced from the first lip portion  350  to define a slot  358  therebetween, For example, an inner lip portion (e.g., the first lip portion  350 ) may define one side area of the slot  358 , and/or an outer lip portion (e.g., the second lip portion  354 ) may define another side area of the slot  358 . The first lip portion  350  and/or second lip portion  354  extend longitudinally generally parallel to each other and/or to the first liner sidewall  340  and/or second linear sidewall  342 . As shown in  FIG. 4 , the slot  358  is sized to retain the enclosure cord  332  within the enclosure channel  344 . For example, the second lip portion  354  may be spaced from the first lip portion  350  a distance  360  (e.g., a second distance) less than the width  348  of the enclosure cord  332  and greater than a width  362  of the enclosure panel  334  (e.g., a second width). In this manner, the enclosure cord  332  may be restricted from passing vertically through the slot  358  while the enclosure panel  334  may be allowed to pass vertically through the slot  358 . 
     In some examples, the retention section  222  includes a first projection  370  and a second projection  372  vertically spaced from the first projection  370  to define a roof channel  374  therebetween. For example, an upper projection (e.g., the first projection  370 ) may define one side area of the roof channel  374 , and/or a lower projection (e.g., the second projection  372 ) may define another side area of the roof channel  374 . The first projection  370  extends laterally and/or longitudinally generally parallel to the second projection  372 . As shown in  FIG. 4 , the roof channel  374  is sized to allow a lip or an edge portion  376  of the roof  120  to extend therethrough. For example, the second projection  372  may be spaced from the first projection  370  a distance  378  similar to and/or greater than a height  380  of the edge portion  376 . In this manner, the edge portion  346  may be selectively and/or removably received in the roof channel  374 , between the first projection  370  and second projection  370 , for removably coupling the roof  120  to the retention section  222 . Is some examples, the first projection  370  and/or second projection  372  enable the track  200  to be coupled to the roof  120  using an interference fit, press fit, or friction fit. Additionally or alternatively, the first projection  370  and/or second projection  372  provide one or more surfaces oriented to receive one or more coupling mechanisms (e.g., fasteners) for coupling the track  200  to the roof  120 . 
     In some examples, the first projection  370  and/or second projection  372  extends laterally from the first linear sidewall  340  and/or second linear sidewall  344  substantially perpendicular to the first linear sidewall  340  and/or second linear sidewall  344 . For example, an outer sidewall (e.g., the second linear sidewall  342 ) may define a deep area of the roof channel  374 . Additionally, the first projection  370  or the second projection  372  may extend between the first linear sidewall  340  and the second linear sidewall  344  to partially define the enclosure channel  344 . For example, a lower projection (e.g., second projection  372 ) may define a deep area of the enclosure channel  344 . 
       FIGS. 5 and 6  show example access sections  224  oriented such that the X-axis  300  defines the outward direction  302  and the inward direction  304 , the Y-axis  310  defines the upward direction  312  and downward direction  314 , and the Z-axis  320  defines the positive longitudinal direction  322  and the negative longitudinal direction  324 . The access section  224  includes an open sidewall  500  coupleable to the first linear sidewall  340  or second linear sidewall  342 . In some examples, a first longitudinal segment of the access section  224  is generally aligned with the retention section  222 , and/or a second longitudinal segment of the access section  224  is substantially perpendicular to the retention section  222 .  FIG. 5 , for example, shows the access section  224  in a generally arcuate configuration.  FIG. 6  shows the access section  224  in a generally linear configuration. In some examples, the access section  224  shown in  FIG. 6  is bent to form the access section  224  shown in  FIG. 5 . 
     The access section  224  is configured to provide access to the longitudinal end portion  226  of an adjacent retention section  222  for selectively and/or removably extending the enclosure cord  332  longitudinally through the enclosure channel  344 . In some examples, the access provided by the access section  224  is generally unobstructed by another portion of the track  200 . For example, a first surface  502  of the open sidewall  500  oriented to face a first direction  504  (e.g., an outer surface facing the outward direction  302 ) may be unobstructed by another portion of the track  200 , and/or a second surface  506  of the open sidewall  500  oriented to face a second direction  508  opposite the first direction  504  (e.g., an inner surface facing the inward direction  304 ) may be unobstructed by another portion of the track  200 . In this manner, when the open sidewall  500  is coupled to an outer sidewall (e.g., the second linear sidewall  342 ), the enclosure cord  332  may be inserted into the enclosure channel  344  from under the roof  120  (e.g., from inside the golf cart  100 ). Alternatively, when the open sidewall  500  is coupled to an inner sidewall (e.g., the first linear sidewall  340 ), the enclosure cord  332  may be inserted into the enclosure channel  344  from outside the golf cart  100 . 
     In some examples, the access section  224  includes a corner lip portion  512  extending laterally from an end portion  514  (e.g., a lower end portion) of the open sidewall  500 . The corner lip portion  512  may provide structure support to the access section  224  and/or the enclosure cord  332 . The corner lip portion  512  may extend in any direction that enables the track  200  to function as described herein. For example, when the open sidewall  500  is coupled to the second linear sidewall  342 , the corner lip portion  512  may be longitudinally aligned generally with the second lip portion  354  of the retention section  222  and/or extend laterally generally in the inward direction  304 . For another example, when the open sidewall  500  is coupled to the first linear sidewall  340 , the corner lip portion  512  may be longitudinally aligned generally with the first lip portion  350  of the retention section  222  and/or extend generally in the outward direction  302 . 
     In some examples, the access section  224  includes a first projection  520  and a second projection  522  vertically spaced from the first projection  520  to define a roof channel  524  therebetween. The first projection  520  may have the same or substantially similar configuration as that of the first projection  370  of the retention section  222 , and/or the second projection  522  may have the same or substantially similar configuration as that of the second projection  372  of the retention section  222 . For example, the first projection  520  may be longitudinally aligned generally with the first projection  370  of the retention section  222 , and/or the second projection  522  may be longitudinally aligned generally with the second projection  372  of the retention section  222 . When the first projection  370  of the retention section  222  and the first projection  520  of the access section  224  are integrally formed, and the second projection  372  of the retention section  222  and the second projection  522  of the access section  224  are integrally formed, the track  200  may define one continuous roof channel that enables the track  200  to be coupleable to the roof  120 . 
       FIG. 7  shows a portion of the track  200  including one or more retention sections  222  and/or one or more access sections  224 . In some examples, the retention sections  222  are generally along the sides  702  of the track  200 , and the access sections  224  are generally at the corners  704  of the track  200 . In this manner, at least a longitudinal segment of an open sidewall  500  of the access section  224  may have a generally arcuate configuration. Alternatively, any section of the track  200  (e.g., retention section  222 , access section  224 ) may be at any segment of the track  200  that enables the track  200  to function as described herein. 
     In some examples, a single retention section  222  having a length of the track  200  is formed, and the retention section  222  is processed to create one or more access sections  224  such that access may be provided to one or more longitudinal end portions  226  of the remaining retention sections  222  from the access sections  224 . For example, one or more sidewalls (e.g., first linear sidewall  340 , second linear sidewall  342 ) and/or lip portions (e.g., first lip portion  350 , second lip portion  354 ) may be removed from a segment of the track  200  to convert a retention section  222  into an access section  224 . Alternatively, one section (e.g., retention section  222 , access section  224 ) may be separately formed and coupled to one or more other sections to fabricate one or more segments of the track  200 . 
       FIG. 8  shows a system  800  for manufacturing or fabricating a track  200 . The system  800  includes a die component  810 , a removal component  820 , and a bend component  830 . The die component  810  is configured to form a raw track. Track materials may be extruded, for example, through the die component  810 . The die component  810  may include, for example, a plurality of die walls  832  arranged generally in a rectangular configuration, and a first member  834  extending substantially perpendicularly from a lower die wall  836  (e.g., a first die wall). The first member  834  includes a body portion  838  corresponding to the enclosure channel  344  and a stem portion  840  corresponding to the slot  358 . For example, the body portion  838  may have a first width (e.g., distance  346 ) such that the die component  810  is configured to form a first linear sidewall  340  between the body portion  838  and an inner die wall  842  (e.g., a second die wall) and a second linear sidewall  342  between the body portion  838  and an outer die wall  844  (e.g., a third die wall). Additionally, the stem portion  840  may have a second width less than the first width (e.g., distance  360 ) such that the die component  810  is configured to form a first lip portion  350  between the stem portion  840  and the inner die wall  842 , and a second lip portion  354  between the stem portion  840  and the outer die wall  844 . 
     In some examples, the die component  810  includes a second member  846  extending substantially perpendicularly from the inner die wall  842  or the outer die wall  844 . The second member  846  is spaced from an upper die wall  848  (e.g., a fourth die wall) and the first member  834  such that the die component  810  is configured to form a first projection  370  between the second member  846  and the upper die wall  848  and a second projection  372  between the second member  846  and the first member  834 . 
     The removal component  820  is configured to locate one or more segments  850  of the raw track at which one or more access sections  224  are to be formed. From the located segments  850 , the first linear sidewall  340  or the second linear sidewall  342  are removed to create one or more access sections  224  such that access may be provided to one or more longitudinal end portions  226  of the remaining retention sections  222  from the access sections  224 . 
     The bend component  830  is configured to locate one or more segments  852  of the track at which one or more bends are to be formed. The bend component  830  may determine, for example, that the track is to be bent at the segments  850  associated with the access sections  224 . The bend component  830  may be configured to bend one or more segments  852  such that at least a longitudinal segment of an access section  224  has a generally arcuate configuration. The bend component  830  may be configured, for example, to bend the segments  852  such that a first longitudinal segment of the access section  224  is generally aligned with a retention section  222  and a second longitudinal segment of the access section  224  is substantially perpendicular to the retention section  222 . In some examples, the bend component  830  includes one or more dies that physically bend the track  200  at the segments  852 . 
       FIG. 9  is a flowchart of an example method  900  of fabricating a track  200 . A raw track is formed at operation  910 . The raw track includes a first sidewall (e.g., first linear sidewall  340 ) and a second sidewall spaced from the first sidewall (e.g., second linear sidewall  342 ) to define a channel (e.g., enclosure channel  344 ) therebetween. The first track may also include a first lip (e.g., first lip portion  350 ) extending from a first end portion of the first sidewall (e.g., lower end portion  352 ) generally toward the second sidewall, and a second lip (e.g., second lip portion  354 ) extending from a second end portion of the second sidewall (e.g., lower end portion  356 ) generally toward the first sidewall. The second lip may be spaced, for example, from the first lip to define a slot (e.g., slot  358 ) sized to retain an enclosure cord (e.g., enclosure cord  332 ) in the channel. 
     In some examples, the raw track is formed to include a first projection (e.g., first projection  370 ) and a second projection (e.g., second projection  372 ) spaced from the first projection such that the first projection and the second projection define a channel (e.g., roof channel  374 ) sized to receive an edge portion  376  of the roof  120  of the golf cart  100  (shown in  FIG. 1 ). The first projection and/or the second projection may be substantially perpendicular to the first sidewall and/or the second sidewall. Additionally or alternatively, the first projection or second projection may extend between the first sidewall and the second sidewall to partially define the channel defined between the first sidewall and the second sidewall. 
     One or more access sections of the raw track (e.g., access section  224 ) are located at operation  920 . From the located access sections, the first sidewall or the second sidewall are removed at operation  930  to provide a partially-processed track. Moreover, one or more of the located access sections are bent at operation  940  to provide a processed or custom track. A first access section, for example, may be bent such that a first longitudinal segment of the first access section is substantially perpendicular to a second longitudinal segment of the first access section. Additionally or alternatively, the first access section may be bent such that at least a longitudinal segment of the first access section has a generally arcuate configuration. After one or more processing operations (e.g., operation  910 , operation  920 , operation  930 , and/or operation  940 ), the custom track may be coupled to the roof  120  of the golf cart  100 . 
     Upon coupling the custom track to the roof  120 , an installer may couple an enclosure  330  to the roof  120  using the custom track. In this manner, the custom track enables the installer to couple the enclosure  330  to the roof  120  without any additional tools or hardware. A longitudinal end portion  226  of a retention section  222 , for example, may be identified adjacent to an access section  224 , and an enclosure cord  332  of the enclosure  330  may be inserted into an enclosure channel  344  at the longitudinal end portion  226 . The enclosure cord  332  may be pushed from the longitudinal end portion  226  to move or slide the enclosure cord  332  longitudinally along the enclosure channel  344 . In some examples, the first lip portion  350  and/or second lip portion  354  provides support to the enclosure cord  332  from below while the enclosure panel  334  hangs between the first lip portion  350  and/or second lip portion  354 . Additionally or alternatively, a portion of the enclosure panel  334  extending through the slot  358  or hanging below the slot  358  may be pulled longitudinally along the slot  358  to move or slide move or slide the enclosure cord  332  longitudinally along the enclosure channel  344 . Upon extending the enclosure cord  332  through a length of one retention section  222 , the enclosure cord  332  emerges from the enclosure channel  344  at the opposite longitudinal end portion of the retention section  222  and may be further inserted into another enclosure channel  344 . In this manner, the enclosure  330  may be coupled to the roof  120  at one or more retention sections  222  in an efficient, quick, and convenient manner. Additionally, the enclosures  300  may be easily removed from the track  200  and/or the track  200  may be disassembled from the roof  120  in an efficient, quick, and convenient manner.
