Abstract:
The presently disclosed embodiments, as well as features and aspects thereof, are directed towards providing a modular cart system operable in multiple configurations suitable for multiple transport applications and, more particularly, for a modular cart system that includes a multi-purpose chassis member. Advantageously, embodiments of a multi-purpose chassis member include various features that provide for either the receipt of a component included in a modular cart system or, alternatively, mechanical coupling to fixtures that are exclusive from the modular cart system. Importantly, because a multi-purpose chassis member is configured for the receipt of various components that may or may not be comprised within a given cart arrangement, a modular cart system that includes a multi-purpose chassis member can be reconfigured for a custom transport solution depending on application. That is, unlike typical cart devices, a modular cart system that includes a multi-purpose chassis member can be configured and reconfigured to take the form of a cart that is most desirable or advantageous to the user.

Description:
BACKGROUND 
       [0001]    Most would agree that the wheel has become the icon for man&#39;s ingenuity. The mother of all inventions, if you will. But, should it be? After all, a wheel is of little use without an axle. Considering this, perhaps it is the thought of the humble axle that should inspire man to innovate and improve. Of course, when one takes time to ponder the endless usefulness of wheels coupled to axles, the question begs as to whether either landmark innovation deserves all the attention. After all, what good is a pair of wheels and an axle without a chassis mounted on top? Regardless of where the accolades should land individually, it is the resulting combination of wheels, axle and chassis—i.e., the tried and true cart, wagon or trailer—that is the real star. 
         [0002]    Carts, wagons and trailers have been around for millenniums, working hard to make man&#39;s life easier, if not more productive. Along the way, countless improvements have been made to the various members or components that comprise a cart. Wheels have been made of rubber, to provide longer wear and a smoother ride. Axles have been modified to include bearings, to lessen friction with the wheel. And chassis designs have been expanded to include springs that soften the cargo ride and hitches that connect to a towing means. And those are but a small sample of the improvements that have been made to the familiar components comprised within a cart. 
         [0003]    Likewise, seemingly endless configurations of the cart itself have been offered for as many different applications. Some carts have even been designed with multiple applications in mind, configured such that a given embodiment may be transformed into various states. For instance, in an effort to provide one cart that is well suited for many applications, inventors have devised carts operable to transform from one configuration or state to another. Transformable cart embodiments may take the form of a wagon in one state, a chair in another state and a table in a third state. 
         [0004]    The common factor among transformable carts, regardless of a given cart&#39;s particular design or functionality, is that a given member comprised within the cart will be repurposed depending on the state of configuration. For example, a component operable as a bed when in a “wagon” state may be operable as a “seat back” in a chair state. Similarly, a chassis member operable to support a wagon bed in a “wagon” state may become an armrest in a chair state. 
         [0005]    Regardless of whether a cart, wagon or trailer takes the traditional form of a chassis rigidly fixed to a set of wheels and an axle or the more trendy form of a chassis, wheels and axle combination that is transformable into multiple configurations, the various members comprised within a given embodiment serve a single purpose when in a transport state. That is, even in the transformable embodiments, the cart state can only take on one configuration because the comprised components are configured for one purpose. As such, carts, wagons and trailers known in the art are most useful only in the particular transport applications for which each was designed. 
         [0006]    Therefore, what is needed in the art of carts, wagons and trailers is a modular cart system that can be custom configured for specific transport applications. Further, what is needed in the art is a modular cart system comprising a multi-purpose chassis member. 
       BRIEF SUMMARY 
       [0007]    The presently disclosed embodiments, as well as features and aspects thereof, are directed towards providing a modular cart system operable in multiple configurations suitable for multiple transport applications and, more particularly, for a modular cart system that includes a multi-purpose chassis member. Advantageously, embodiments of a multi-purpose chassis member include various features that provide for either the receipt of a component included in a modular cart system or, alternatively, mechanical coupling to fixtures that are exclusive from the modular cart system. Importantly, because a multi-purpose chassis member is configured for the receipt of various components that may or may not be comprised within a given cart arrangement, a modular cart system that includes a multi-purpose chassis member can be reconfigured for a custom transport solution depending on application. 
         [0008]    That is, unlike typical cart devices, a modular cart system that includes a multi-purpose chassis member can be configured and reconfigured to take the form of a cart that is most desirable or advantageous to the user. Notably, while the term “cart” is often used in the present specification to refer to the various configurations that a given embodiment of a modular cart system having a multi-purpose chassis member may take, it will be understood that the scope of a modular cart system, or any system that includes a multi-purpose chassis member, will not be limited to “cart” configurations. It is envisioned that embodiments including a multi-purpose chassis member will be directed toward wagons, trailers, motorized apparatuses or any other mode of transport. 
         [0009]    A multi-purpose chassis member may be configured for the receipt of an axle. More particularly, a multi-purpose chassis member may include features or aspects that enable the multi-purpose chassis member to be quickly coupled and decoupled from an axle component. When coupled to an axle component having wheels, for example, a multi-purpose chassis member will provide for the receipt of other components suitable for a particular purpose or transport application. As an example, one embodiment of a multi-purpose chassis member may be configured to receive vertical cargo support members that are capable of supporting a particular object such that, when the chassis member is coupled to an axle with wheels, the particular object can be transported. 
         [0010]    As a more specific example, an embodiment of a multi-purpose chassis member may be configured for receipt of a component that is suited for retention of a bicycle. Such a component, for example, may be a channel or bracket that can be fixedly received by a multi-purpose chassis member so that a bicycle can be subsequently coupled to the component. The embodiment of the exemplary multi-purpose chassis member may also receive a hitch component and then be coupled to an axle with wheels so that the bicycle can be pulled to another location. Alternatively, the same embodiment of a multi-purpose chassis member may be decoupled from the hitch component and the axle and wheels and then mounted to a larger trailer flatbed, truck bed, luggage rack or the like such that the bicycle, safely secured to the exemplary channel component, can be transported. 
         [0011]    As another example of a modular cart system that includes a multi-purpose chassis member embodiment, it is envisioned that two multi-purpose chassis members may be coupled to an axle and wheels and slidably positioned along the axle at a predetermined, or selected, distance apart. The exemplary chassis members, being configured for receipt of vertical cargo support components, may each receive two vertical cargo support components at either distal end of the chassis member. Subsequently, the corresponding vertical cargo support components may be communicatively coupled by a strap, or other mechanism, such that an object may be suspended and supported via the straps. For illustrative purposes only, such an embodiment of a modular cart system may be suitable for transport of a kayak or canoe, wherein the kayak or canoe can be saddled via the aforementioned straps. Advantageously, the exemplary canoe may be pulled via a hitch component of the modular cart system to wherever the user desires. 
         [0012]    Expanding on the exemplary embodiment described above in relation to canoe transport, the same embodiment may be configured such that the vertical cargo support components and straps can be removed. Subsequently, the same embodiment of the modular cart system may be configured to receive the bicycle channels described above relative to a different embodiment. As such, one skilled in the art will understand that the modular cart system can leverage the multi-purpose chassis member such that the system can be changed between configurations ideally suited for different transport applications. 
         [0013]    Another embodiment of a modular cart system may be configured for receipt of sled or ski components in lieu of an axle/wheel component. Such an embodiment would advantageously provide a user with the option of configuring a transport solution according to applications ranging from asphalt roads to snowy trails. Additionally, embodiments of a modular cart system that include a multi-purpose chassis member may provide a user with the option of configuring a transport solution for pulling by ATV, vehicle, sled dog team or whatever means available. 
         [0014]    Regardless of the particular embodiment of a modular cart system that may be used, it is a common aspect among all embodiments that a multi-purpose chassis member will be included. One skilled in the art will understand that the multi-purpose chassis member provides a user of a modular cart system with a means for selecting and configuring various components that are best suited for a specific transport application. Further, various components that may be included in a modular cart system embodiment, and received by a multi-purpose chassis member, in order to best configure a transport solution for a particular transport application will occur to those with skill in the art. As such, the particular embodiments, component combinations, transport solutions or cart configurations described in this application are offered for illustrative purposes only and will not be interpreted to limit the scope or application of a modular cart system which includes a multi-purpose chassis member.

     DETAILED DESCRIPTION 
       [0031]    The presently disclosed embodiments, as well as features and aspects thereof, are directed towards providing a modular cart system that can be custom configured for specific transport applications by leveraging a multi-purpose chassis member (MPCM). Exemplary embodiments of an MPCM are disclosed herein in the context of carts, wagons and trailers, however, one of ordinary skill in the art will understand that various embodiments may also comprise any combination of features and aspects useful for other applications related to, but not limited to, motorized vehicles, man-powered transportation modes, cargo carriers, luggage transport systems, etc. Moreover, as most of the described embodiments are disclosed in the context of carts, wagons and trailers, one of ordinary skill in the art will understand that the reference to a “cart” in this description is not intended to limit the use of a MPCM to be in conjunction with a cart, wagon or trailer embodiment. Rather, the terms cart, wagon, trailer or other term used to generally label a disclosed embodiment will be understood to anticipate any modular cart system comprising at least one MPCM. As such, the description herein of embodiments specifically configured for cart-like transport solutions will not be interpreted to limit the scope of a MPCM. 
         [0032]    As has been described, a MPCM may be configured for the receipt of an axle. More particularly, a MPCM may include features or aspects that enable it to be quickly coupled and decoupled from an axle component. When coupled to an axle component having wheels, for example, a MPCM will provide for the receipt of other components suitable for a particular purpose or transport application. Further, it is envisioned that some embodiments of a MPCM may be configured for the receipt of other components made of readily accessible or standard building materials such as, but not limited to, various lumber products, PVC piping, rebar, angle iron, channel, bolts, clips, etc. 
         [0033]    Turning now to the figures, where like reference numerals represent like elements throughout the drawings, various aspects, features and embodiments of a multi-purpose chassis member (MPCM), and modular systems comprising one or more MPCMs, will be presented in more detail. The examples as set forth in the drawings and detailed description are provided by way of explanation and are not meant as limitations on the scope of a MPCM, the methods for using a MPCM or the transport solutions that may be generated by a modular cart system comprised of a MPCM. A MPCM thus includes any modifications and variations of the following examples as come within the scope of the appended claims and their equivalents. 
         [0034]      FIG. 1  depicts an exemplary embodiment of a multi-purpose chassis member (MPCM)  100 . Although not required in all embodiments of a MPCM, the exemplary MPCM  100  is manufactured from a single stock having a top surface  102 , a bottom surface  104  (not shown), front and back surfaces  106  (front not shown), and left-side and right-side surfaces  108  (left-side not shown). The MPCM may be constructed from any material suitable for a given transport application including, but not limited to, wood, aluminum, cast iron, steel, plastics, etc. Importantly, while the exemplary MPCM  100  is depicted such that the features and aspects to be described are symmetrical, it is envisioned that some embodiments of an MPCM will not be as such. The particular combination and placement of features in a MPCM embodiment may driven by the need for various configurations of transport solutions and may be novel in and of itself; however, the scope of a MPCM will not be limited by any particular combination of features or placement of features comprised within a given MPCM embodiment. 
         [0035]    The MPCM  100  features a number of modular cart system component receipt features, including an axle channel  110  traversing the bottom surface  104  from the left-side  108  to the right-side  108  of the MPCM  100 . Although not shown in  FIG. 1 , it will be understood that the axle channel  110  of MPCM  100  extends all the way across bottom surface  104  from left-side  108  to right-side  108 . However, it is envisioned that some embodiments of a MPCM may comprise features that do not fully extend across a MPCM, yet are suitably configured for the receipt of an axle or other modular cart component. Turning back to axle channel  110 , an axle (not shown) may be received into the channel  110  such that the MPCM  100  is positioned (front to back) substantially perpendicular to the axle. Once the axle is received into axle channel  110 , the MPCM  100  may be “slid” or positioned anywhere along the axle as is desired by a user. Once the MCPM  100  is positioned on the axle, the axle may be secured to the MPCM  100  via various means known in the art including, but not limited to, U-bolts. For exemplary purposes only, and not to limit the means of securing an axle to a MPCM embodiment, a U-bolt may be positioned in communication with a received axle such that the axle rests in the “saddle” of the bolt and the ends of the bolt extend through top surface  102  of MPCM  100  at axle securing features  115 . Once the U-bolts are thusly positioned, an axle may be secured to MPCM  100  via application of nuts or other means known in the art for preventing the U-bolts from retracting from axle securing features  115 . 
         [0036]    MPCM  100  is depicted such that axle channel  110  is positioned substantially in the middle of MPCM  100 . It will be understood, however, that such is just for exemplary purposes and that other embodiments of an MPCM may feature an axle channel, if at all, in a position closer to one end of the particular MPCM embodiment. Further, some embodiments of a MPCM having an axle channel  110  may also include an insert component  160 . Insert component  160 , in lieu of an axle, may be received into axle channel  110  and secured such that the channel is reduced in size. Advantageously, by use of the insert component  160 , MPCM  100  may be configured for receipt of an alternative modular cart system component to the axle such as, for example, a car rack or rail system. 
         [0037]    Exemplary bores  120  in MPCM  100  are configured for the receipt of a modular cart system component in the form of a piece of 2×4 lumber or other components having a rectangular cross-section. Advantageously, because bores  120  are configured in a “cross,” one skilled in the art will understand that a modular cart system component having a rectangular cross-section can be securely positioned in either of two orientations relative to the MPCM  100 . Importantly, although the exemplary bores  120  are depicted in a cross such that a modular cart system component having a rectangular cross-section may be oriented in one of two orientations relative to MPCM  100 , such will not limit the scope of multi-orientation bores that may be comprised within a given embodiment of a particular MPCM. For example, it will be understood that other MPCM embodiments may comprise multi-orientation bores such as, but not limited to, star shaped bores that are configured for more than two orientations of a given modular cart system component. Further, it will be understood that some multi-orientation bores comprised within a given embodiment of a MPCM may be configured for orienting modular cart system component that have cross-sections other than rectangular. 
         [0038]    Various modular cart system components may be received into bores  120 , or other bores or features in a given MPCM embodiment, such that a useful support structure is created. For example, a pair of MPCMs  100  may be positioned and secured to an axle as described above. Subsequently, a series of vertical cargo support members having rectangular cross-sections may be received, respectively, into each of the four bores  120  such that the vertical cargo support members are secured in an upright and perpendicular position relative to the MPCMs. Straps, or other support means, may be secured between pairs of the vertical cargo support members such that the straps reach from the uppermost end of one support member to the uppermost end of another support member, thereby creating a pair of saddles useful for receiving a cargo. 
         [0039]    Similar to bores  120 , other component receipt features may be included in various embodiments of a MPCM. For example, MPCM  100  includes cylindrical bores  125 , configured for receipt of modular cart system component having either a round cross-section or a maximum diameter less than the diameter of the bore. It will be understood that, although bores  125  are described as “cylindrical,” some system component receipt features, whether of a bore design or not, may have tapered walls or other means for convenient receipt or securing of a modular cart system component. Further, it is envisioned that while some system component receipt features may be configured to secure a modular cart system component via complimentary geometry only, other system component receipt features may include securing mechanisms such as, but not limited to, locks, magnets, pins, latches or the like. 
         [0040]    System component receipt features  130  included in MPCM  100  are configured for receipt of a tether and washer combination. More specifically, system component receipt features  130  are comprised of “T-shaped” channels bored into the top surface  102  of MPCM  100 . A pair of parallel T-channels  130  is depicted at both ends of MPCM  100 . Advantageously, a tether extended through a standard washer or the like, and knotted such that the tether cannot be pulled back through the washer, can be received by a T-channel  130  such that the washer slides into the portion of the T-channel that is parallel to the plane of top surface  102 . Once received into the parallel portion of T-channel  130 , the tether can be used to secure cargo or other modular cart system components to the MPCM  100 , as application of a pulling force on the tether will serve to pull the washer deeper into the parallel portion of the T-channel  130  thus generating a suitable anchor point for the tether. 
         [0041]    To illustrate the multi-function aspects of various features that may be comprised within a given embodiment of a MPCM, it is envisioned that T-channel member receipt features  130  may also be useful for the receipt of a surfboard fin. In such an application, the fin of the surfboard may be slid into T-channels  130  such that the board is positioned for secure transport. 
         [0042]    System component receipt feature  135  consists of a bore into either the front or back surfaces  106  of MPCM  100  and may be used for the secured receipt of, among other modular cart system components, a push-cart or pull-art handle assembly. In other embodiments, system component receipt feature  135  may be used to securely receive a trailer tongue assembly, dumping handle or any other modular cart system component as may be deemed useful by a user. 
         [0043]    MPCM  100  also comprises a channel receipt feature  140  that may be used in connection with anchor points  145  to position and secure a deck, or other flatbed surface, between a pair of MPCMs. For example, a modular cart system component in the form of a deck may be simultaneously slid into the channel receipt features  140  of two or more MPCMs  100  positioned in parallel along one or more axles. The exemplary deck component, once slid into the channel receipt features  140 , may thusly be secured by way of bolts or other fastening means through holes  150  or anchor point grooves  145 . Advantageously, one skilled in the art will understand that a deck or similar modular cart system component that is received and secured between two or more MPCMs will serve to unify the modular cart system and provide for a useful cargo carrying surface. 
         [0044]    MPCM  100  further features a series of anchor points  155  in the form of holes bored through a channel in the sides  108 . The anchor points  155  may be used for receipt of fasteners for securing various system components or hooks, straps, tie-downs, bungees or the like for securing cargo. Anchor points  155  are depicted for exemplary purposes only and, as such, all embodiments of a MPCM may not feature such anchor points or features. Further, it will be apparent to those skilled in the art that the various features illustrated and described relative to the embodiment of  FIG. 1  may be leveraged for uses beyond the exemplary uses described herein. 
         [0045]      FIGS. 2A-16B  are directed toward exemplary transport solutions that may be configured from various modular cart systems comprised of one or more MPCMs such as, but not limited to, MPCM  100 . Figs. A-Z are offered herein for illustrative purposes only and, as such, are not intended as a comprehensive representation of all envisioned transport solutions that may be configured from a given modular cart system embodiment. Further, while various transport solution configurations, and the modular cart system components used for those configurations, may be novel in and of themselves, the transport solutions described and depicted do not limit the scope of a modular cart system comprised of a given MPCM. 
         [0046]      FIGS. 2A-2C  illustrate top, back and side views, respectively, of an exemplary strap carrier transport solution  200  configured from a modular cart system comprising a multipurpose chassis member. Referring to  FIG. 2C , the form of a boat, canoe or kayak is depicted as a cargo being transported by the strap carrier solution  200 . However, it will be understood that a strap carrier solution  200  may be useful for transport of other cargo besides that which is depicted. 
         [0047]    Generally, the strap carrier transport solution  200  consists of two MPCMs  210  in communication with an axle  215  and wheels  220 , as has been described relative to the  FIG. 1  embodiment  100 . Inserted into component receipt features of the MPCMs  210  are a series of four vertical cargo support members  225 . A strap  230  may be extended between the distal ends of parallel vertical cargo support members  225  such that a saddle spans between the two MPCMs  210 . While it is envisioned that some transport solutions may further comprise a component configured for pulling the modular cart system, the particular exemplary transport solution  200  serves to support cargo placed in the strap  230  saddle while a pulling force may be applied to the cargo itself. 
         [0048]      FIGS. 3A-3C  illustrate top, back and side views, respectively, of an exemplary scupper carrier transport solution  300  configured from a modular cart system comprising a multipurpose chassis member. Referring to  FIG. 3C , the form of a boat, canoe or kayak is depicted as a cargo being transported by the scupper carrier solution. However, it will be understood that a scupper carrier solution may be useful for transport of any cargo comprising a scupper, hole or recess. 
         [0049]    Generally, the scupper carrier transport solution  300  consists of two MPCMs  310  in communication with an axle  315  and wheels  320 , as has been described relative to the  FIG. 1  embodiment  100 . Inserted into component receipt features of the MPCMs  310  are a pair of vertical cargo support members  325 . As can be seen in the  FIG. 3B  depiction, the vertical cargo support members  325  are spaced along the axle  315  such that each can be inserted through a scupper hole. While it is envisioned that some transport solutions may further comprise a component configured for pulling the modular cart system, the particular exemplary transport solution  300  serves to support cargo placed on the scupper support members  325  while a pulling force may be applied to the cargo itself. 
         [0050]      FIGS. 4A-4C  illustrate top, side and front views, respectively, of an exemplary beach cart transport solution  400  configured from a modular cart system comprising a multipurpose chassis member. Generally, the beach cart transport solution  400  consists of two MPCMs  410  in communication with an axle  415  and wheels  420 , as has been described relative to the  FIG. 1  embodiment  100 . Inserted into component receipt features of the MPCMs  410  are a series of four vertical cargo support members  425 . A net or other barrier component  430  may be supported by vertical cargo support members  425  such that a cargo carrying space is defined above the two MPCMs  210 . Also, a handle component  435  of the modular cart system is depicted as being either integral to or received by, as the particular embodiment may dictate, one or more vertical cargo support members  425  such that the beach cart transport solution  400  can be tilted and pulled from one location to another. 
         [0051]      FIGS. 5A-5C  illustrate top, back and side views, respectively, of an exemplary 2-wheel utility cart transport solution  500  configured from a modular cart system comprising a multipurpose chassis member. Generally, the 2-wheel utility cart transport solution  500  consists of two MPCMs  510  in communication with an axle  515  and wheels  520 , as has been described relative to the  FIG. 1  embodiment  100 . Inserted into component receipt features of the MPCMs  510  cargo support component  525 . The cargo support component  525  is supported by the two MPCMs  510 .
