DETAILED DESCRIPTION
Referring to the FIGURES, a modular frame and structure system is shown according to various exemplary embodiments. The system is shown to include elongated frame members of varying lengths and a variety of coupling members that quickly and securely connect to one or more of the frame members to create a framework, and a variety of covers (e.g. skins, etc., such as soft/flexible, hard/rigid, mesh, transparent, etc.) for use in customizing the framework into a particularly desired structure. According to any of the illustrated embodiments, the system is intended to provide a readily-transported, quickly-assembled and easily-reconfigurable modular structure that can be rapidly deployed to provide a quick structural solution as a shelter, dwelling, enclosure or the like to support any of a wide variety of activities such as (but not limited to) base camps, outposts, aid stations, disaster relief, military operations, receptions, command and control operations, kennels, livestock management (e.g. chicken coops, etc.), gardening and agriculture (e.g. greenhouses, etc.), sporting events, recreation events, commercial activities such as farmers markets, etc.
Referring to FIGS. 1A-B, a framework for a modular frame and structure system 10 (shown in FIG. 2) is shown according to an exemplary embodiment. The modular frame and structure system 10 includes a framework shown as framework 20, including elongated frame members 12 (e.g. poles, etc.) of varying lengths and a variety of coupling members or connectors 14 and in-line couplers 16 that quickly and securely connect to one or more of the frame members 12 to create the framework 20. The connectors 14 include releasable connecting devices (not shown) so that the connectors 14 can be removed and/or reinstalled on an existing framework 20 substantially in-situ without having to significantly disassemble the framework 20, so that modifications or adaptations of the framework 20 may be quickly and easily accommodated. In other embodiments, the framework 20 can have another configuration of frame members 12, connectors 14, and couplers 16 that is suited for the particular application.
Referring still to FIGS. 1A-B, the elongated frame members 12 (e.g., tubes, pipes, poles, etc.) are joined together with a variety of coupling devices or connectors 14 to create various framework geometries and configurations. According to an exemplary embodiment, the frame member 12 is a hollow, cylindrical member configured to provide suitable rigidity and strength to the framework 20 to allow the framework 20 to be a freestanding structure that does not deform excessively (e.g., bend, sag, twist, etc.) due to dead loads (e.g., the weight of the framework 20, the weight of the covers, etc.), contact from persons utilizing the system 10, or live loads such as environmental loads (e.g., snow, leaves, wind, etc.). The frame members 12 are preferably relatively lightweight to facilitate the transport and erection of the frame and structure system 10. According to exemplary embodiments, the frame members 12 are formed of aluminum. In other embodiments, the frame members 12 may be formed of another metal or alloy. In still other embodiments, the frame members 12 may be formed of a polymer (e.g., a thermoplastic thermoset plastic, etc.) or a composite material. Likewise, the connectors 14 may be formed of any material (e.g., metal, alloy, polymer, composite, nylon, etc.) that provides a sufficient rigidity and strength and is able to withstand bending moments applied to the connectors 14 by the frame members 12.
The frame members 12 may be provided in a variety of lengths. In one embodiment, the frame members 12 may be provided in a limited number of standardized lengths to reduce confusion during assembly of the frame and structure system 10. In some embodiments, several frame members 12 may be aligned and coupled together utilizing in-line couplers 16 to create longer lengths. The coupler 16 is shown as a tubular member with ends configured to receive the ends of the frame members 12. The ends of the frame members 12 may be chamfered or tapered to facilitate the insertion of the frame members 12 into the couplers 16. The ends of the frame members 12 and the couplers 16 include features to lock the frame members 12 and the couplers 16 together.
Referring to FIGS. 2-4, the system 10 further includes a variety of covers 18 (e.g. skins, etc., such as soft/flexible, hard/rigid, mesh, transparent, etc.) for use in customizing the framework 20 into a particular desired structure. The covers 18 may include any of a variety of materials having desired functional and aesthetic characteristics to suit an intended application. The covers 18 may be waterproof and insulated, may include openings such as windows or vents for climate control, and may include passageways such as doors.

Referring to FIG. 24, a system 300 is shown having another cover configuration for use with the framework 20, according to another exemplary embodiment. In this embodiment, the wall panels 22 and/or roof panels 32 may include other features, such as built-in and selectively deployable flaps 50 (such as canopies, awnings, etc.), or such panels 22 or 32 may be releasably attached with quick-connect fasteners (not shown) to provide further flexibility in providing customizable structures suitable for use in any of a wide variety of applications. The system 300 may also include strengthening panels 48 at stress-locations, such as corners, or other areas that engage the frame members 12 or connectors 14 of the framework 20.
Referring now to FIGS. 25-32, multiple frame members 12 may be coupled together at joints at various angles using multi-point coupling devices or connectors 14. The multi-point connectors 14 include a multitude of tubular sockets 58. Gussets 60 (e.g., braces, supports, etc.) may be provided between the tubular sockets 58 to reinforce and strengthen the connector 14. The connector 14 may further include other features, such as a rib 62 or strut to facilitate the stringing of electrical cords or lines (e.g. from solar panels to energy storage devices such as batteries and the like, or to electrical appliances, etc.), or for routing hoses or tubing (e.g. water collection or distribution, or distribution of medical supplies, etc.), or the attachment of other items such as equipment (portable lights, appliances, medical apparatus, etc.) covers or any of a wide variety of other components (e.g., using a carabiner or other suitable connector, as described below).
The frame members 12 are connected to the multi-point connectors 14 in a manner similar to the coupling system described above in reference to the in-line couplers 16. A wide variety of multi-point connector 14 configurations are possible to facilitate the creation of trusses and other structures for the modular frame and structure system 10. For example, connectors may be utilized for two, three, or four coplanar frame members that are oriented orthogonally by two-point connector 140, a three-point connector, and four-point connector 144, respectively (see FIGS. 25-26); for three, four, five or six frame members that are oriented orthogonally on multiple planes by six-point connector 146, five-point connector 148, a four-point connector, and three-point connector 152, respectively (see FIGS. 27-29), or for frame members that oriented at some other angle relative to each other (e.g., approximately 90 and 120 degrees) by three-point connector 154 or four-point connector 156 (see FIGS. 30-32). The advantageous features of these connectors 14 can be provided to support interconnection of frame members 12 in any of a wide variety of angles and configurations to support a particular application. Further, using short length couplers 16, multiple connectors 14 may be joined together to provide further capability to support customized coupling configuration requirements for a wide variety of applications.
Referring again to FIG. 32, a connector 14 is shown disassembled according to an exemplary embodiment, which is intended to provide the capability of allowing an ‘interior’ connector 14 to be decoupled from neighboring frame members 12 without having to substantially disassemble the framework 20 (e.g., disassembling other frame members and connectors from the accessible outside of the framework towards the inside). As shown, the connector 14 is split into two body halves 64 and 66 along a split line 68 that is aligned with at least one of the sockets 58. In other embodiments, the connector body 14 may have multiple split lines and separate into three or more portions.
The two halves 64 and 66 of the connector body 14 may be held together with suitable connectors, such as (but not limited to) a threaded fastener 70. As shown in FIG. 55, the threaded fastener 70 may be received in an opening in one of the sockets 58 that is not split. The threaded fastener 70 may engage a threaded hole in the connector body 14 or may pass through a hole to engage a threaded post or another suitable fastener, such as a nut. In other embodiments, the threaded fastener 70 may be provided elsewhere, such as on a flange or other portion of the connector body 14 outside of the socket 58. In further embodiments, the portions of the connector body 14 may be releasably joined together using other devices, such as by use of collars 74 or slip-rings disposed around the ends of the receptacles 230 for the frame members 12. While the receptacles 230 have been shown as circular or cylindrical receptacles 230 for receiving mating cylindrical poles such as frame members 12, the receptacles 230 and collars 74 may have any suitable shape to receive poles such as frame members 12 or other support members having a desired shape for a particular application.
Referring still to FIG. 32, collars 74 (e.g., rings, sleeves, etc.) may be provided to further couple the connector body halves 64 and 66 together. Collars 74 surround the distal ends of the receptacles 230 on the split sockets 58 to prevent the sockets 58 from splitting apart inadvertently (e.g., because of a bending moment applied to the socket by the frame member) and to structurally reinforce the mouth of the receptacle 230. Collars 74 may also be provided for the non-split sockets 58 to reinforce the sockets 58. The collars 74 are configured to be quickly and easily removable, such as by an interference type slip-fit. In one exemplary embodiment, the collars 74 are coupled to connector body receptacle halves with a threaded connection. In other embodiments, the collars 74 may be coupled to the connector body receptacle halves with a snap fit or may be coupled to the connector body halves with an interference fit or another suitable connection, such as with a bayonet connection.
The frame member 12 received in the split socket 58 of a connector 14 may be removed by moving the frame member 12 perpendicular to the longitudinal axis of the frame member 12 instead of along the longitudinal axis. The connectors 14 may be disassembled by removing the collars 74 from the sockets 58 along the split line 68 and removing the threaded fasteners 70 (if any). The connector body halves 64 and 66 may then be separated along the split line 68 by disengaging any integrally formed coupling features, such as tabs on the ribs 62. In this way, the portions of the connector body 14 may be decoupled and need only be pulled away from each other until a sufficient clearance is created between the portions of the connector 14 to allow the frame member 12 to pass through. According to an exemplary embodiment, the frame members 12 are removed by rotating the free end (i.e., the end normally coupled to the split connector) about the opposite fixed end until the free end is moved out of the gap between the connector body halves 64 and 66 and is clear of the connector 14. This action is intended to apply less stress to the surrounding components of the framework 20 than otherwise attempting to pull the frame member 12 out along the longitudinal axis.
Other connectors 14 may be provided to increase the functionality and design flexibility of the modular frame and structure system 10. Referring to FIG. 33, hinged connector 158 (e.g., corner clamp connectors) is shown. Hinged connector 158 allows a frame member 12 to be coupled to another frame member 12 at any angle (in the manner of a brace, strut, support or the like). The hinged connector 158 includes a first end 86 that is coupled to the end of a frame member 12 in a removable manner. The first end 86 may be similar to the in-line coupler 16 and the multi-point connectors 14 described above and have an aperture 56 for a coupling device 52 such as a spring-loaded pin and a reinforcing collar 74 or 256. A second end 88 of the hinged connector 158 includes a cylindrical clamp 90 that is pivotably coupled to the first end at a hinge 92 with a removable fastener 94. The second end 88 may be snapped onto a frame member 12 and coupled to the first end 86 with the fastener 94 or the hinged connector 158 may first be assembled and then the second end 88 slipped onto the end of a frame member 12. A frame member 12 (or several frame members coupled together with in-line connectors or multi-point connectors) with hinged connector 158 on either end may be utilized as an angled brace to strengthen and add rigidity to the framework 20, as shown in FIG. 1.
Referring to FIG. 34, a vertical frame member 12 may be coupled to a foot 104 in a removable manner. The foot 104 may be similar to the in-line coupler 16 and the multi-point connectors 14 described above and have an aperture for a coupling device 52 such as a spring-loaded pin and a reinforcing collar 74. The foot 104 may be used as a generally horizontal base for a vertically-oriented frame member 12, or may be coupled to a generally vertical surface and used as a support for a generally horizontally-oriented frame member 12. Although the foot 104 is shown having a receptacle 106 extending substantially perpendicular to the base, the receptacle 106 may extend at any of a wide variety of angles, such as 60 degrees, 45 degrees, etc. to suit the needs of any particular installation.
Referring to FIG. 35, in-line coupler 16 is shown, according to exemplary embodiments. In-line couplers 16 may be used to couple two frame members 12 of the framework 20. In this embodiment, the in-line coupler 16 is separable into more than one portion and may be coupled together with a fastener 114. In other embodiments, the in-line coupler 16 may be a single piece. The frame members 12 are inserted through the collars 74 of the in-line coupler 16. The in-line coupler 16 is configured to separate at a split line 112.
Referring to FIG. 36, a storage bag for the modular frame and structure system 10 is shown, according to an exemplary embodiment. The storage bag 202 is sized to hold the components of the framework 20, including the frame members 12 and multi-point connectors 14. The storage bag 202 may be made from the same materials as the wall panels 22, or any other materials including fabric materials, such as a rip-stop nylon material or the like. The storage bag 202 may include a shoulder strap 204 for carrying the portable storage bag 202. The shoulder strap 204 may be coupled to the storage bag 202 with any type of clip hardware 206. Some examples of clip hardware 206 are shown in FIG. 38. The storage bag 202 may also include a handle 208 for carrying the storage bag 202. The handle 208 is made from the same material as the bag 202 in exemplary embodiments. The storage bag 202 also includes an opening 210 that is closed by a nylon accessory cord 212. When the cord 212 is pulled away from the opening 210, the storage bag 202 is cinched at the opening 210, closing the storage bag 202. The storage bag 202 includes a cord lock 214 for locking the cord 212 and holding the opening 210 in the closed position. According to one embodiment, after deployment of the components from storage bag to create a structure, the storage bag may then be attached to the structure using any one of the previously described connecting devices to provide a storage compartment internal or external to the structure.
Referring to FIG. 37, an inner bag 216 is shown, according to an exemplary embodiment. The inner bag 216 is configured to store poles, such as the frame members 12. The inner bag 216 includes an opening 218 that is closed by pulling nylon cord 212 away from the opening 218. The cord 212 and opening 218 are then locked in the closed position by a cord lock such as cord lock 214. The inner bag 216 is sized to fit within the storage bag 202, in exemplary embodiments.
Referring to the FIGURES, the modular frame and structure system is configured to be quickly and securely assembled and disassembled using common coupling features (e.g., spring-loaded coupling pins). Further, the connectors for the modular frame and structure system include common parts between them, such as common threaded fasteners and collars. Still further, the connectors themselves may include common geometries along the split line.
