Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Patent Application No.

[0003] 63 / 321,037, the entire contents of which are incorporated herein by reference. Background Art

[0004] The present disclosure relates to expandable structures, and more particularly to expandable structures using interchangeable connectors and expandable members having various structural and functional features. Summary of the invention

[0005] The present disclosure describes a system of components that can be combined to form a modular expandable structure. The structure can be formed using expandable members that are interconnected at corresponding joints. The expandable members can have connectors that interconnect adjacent expandable members, which can be integrated with the expandable members or connected to the expandable members as separate connectors. The structure can have an assembly position in which the expandable member is connected to an adjacent expandable member and allows flow between the expandable member and the adjacent expandable member.

[0006] In some embodiments, the inflatable structure can be formed using various interchangeable components, such as connectors, valves, connector arms, covers, and / or inflatable members, which can be selectively coupled to each other to form the inflatable structure. The connector can be incorporated into the inflatable member itself, or formed as a separate component interconnected with one or more inflatable members to form a framework that can be expanded from a contracted or unexpanded configuration to an expanded or expanded configuration. As further discussed herein, the various advantages and applications of such structures create many opportunities and benefits in a variety of industries.

[0007] One aspect of at least some of the embodiments disclosed herein is beneficial and advantageous in that the structure is easily stored when in a collapsed configuration and rapidly inflated to an expanded configuration such that the structure is ready for use.

[0008] According to some embodiments disclosed herein, the structure may also be modular. Thus, components of the system may be connected to form or modify the shape and / or function of the structure.

[0009] The modularity of the structure enables a variety of unique connectors, pipes, panels, bases and / or other devices, including lighting devices, motors, electrical components and / or plumbing components and / or other features that can be generally incorporated into toys, housing structures or other service structures, where various aspects of the presently disclosed system can have corresponding uses. The modularity of the system can allow a user to expand the system or replace components of the system in order to build a structure specifically designed for the user's specific needs.

[0010] For example, the structures can be used for portable garage spaces for vehicles, trading kiosks, construction equipment for educational, recreational, or commercial purposes, portable structures such as sheds, tents, forts, warehouses, and garages, temporary housing that can be used in emergency situations, obstacle courses, protective shelters from inclement weather, molds for holding or supporting certain types of building materials (e.g., for containing or filling materials such as concrete or other materials that can be sprayed onto or supported by the structure to cure and facilitate formation of a permanent structure, as well as various other construction and recreational applications).

[0011] Alternatively, in some embodiments, no valve may be incorporated into the expandable member and / or connector itself (eg, this may be accomplished by enclosing the expandable member with a closure cap).

[0012] In some embodiments, the system may include an expandable member and a connector made of rigid and / or flexible materials. For example, at least a portion of the connector (such as the body portion of the connector) may be made of a flexible, deformable material. Such embodiments can allow the ports of the connector to move to different angular orientations relative to each other, thereby allowing relative movement of the expandable member coupled to the connector.

[0013] For example, at least a portion of the connector (e.g., the connector body and / or at least a portion of the connector arm or port) can include a flexible material that can deflect or bend as force is applied to an expandable member attached to the flexible material (e.g., at a joint between the expandable member and the connector) when a bending stress is applied to the expandable member or joint.

[0014] Additionally, in some embodiments, at least a portion of the connector (eg, a connector arm) can be rigid to allow for a secure connection or seal between the connector and an expandable member coupled to the connector.

[0015] According to some embodiments, the connector may be incorporated into the inflatable structure itself and facilitate interconnection with at least one other connector or inflatable structure. In some embodiments, the connector may be formed as a separate component from the inflatable structure and may be used to interconnect with one or more inflatable structures.

[0016] Thus, when the connector is formed as a separate component from the inflatable structure of the system, the connector is formed without a valve, but when connected to the connecting portion of the inflatable structure, the connector can function to interact (e.g., open and / or close) with a valve constructed or incorporated into the connecting portion of the inflatable structure.

[0017] For example, when the connector is inserted into the coupling portion of the expandable structure, whether manually by the user or through interaction with the expandable member, the valve can be opened to allow fluid communication between the expandable structure and the connector. The valve can also be closed manually by the user or when the connector is removed from the expandable member.

[0018] Alternatively or additionally, the connector itself may include a valve, and the inflatable structure may be formed without a valve. When the connector is coupled to the inflatable structure, the valve of the connector may be opened and / or closed (whether manually by a user or through interaction with the inflatable member), thereby allowing fluid communication between the inflatable structure and the connector.

[0019] In some embodiments, the connector may also be formed without a valve so that fluid flow through the connector is unimpeded. Such embodiments may also be used with an inflatable structure without a valve to form a system with unimpeded airflow from one inflatable member through the connector and into another inflatable member. The connector of such an embodiment may be used to interconnect two or more inflatable structures and allow fluid to flow between these inflatable structures.

[0020] In some embodiments, the connector can be coupled to the inflatable structure without opening the valve, thereby not allowing fluid to flow between the inflatable structure and the connector. Thus, in some embodiments, the valve can be incorporated into a connector formed separately from the inflatable member, incorporated into an inflatable member that includes the connector or is formed as a single component with the connector, or omitted entirely from both. Thus, the valve can be formed as a separate component that can be coupled to the connector and / or the inflatable member. In addition, a closure cover can be used to provide a seal for any port or hole of any component of the structure.

[0021] Optionally, the connection between the expansion tube and the connector can achieve a mechanical or structural connection, such as various engagement features (protrusions and / or grooves) and / or friction fit. For example, both the expandable member and the connector can include ports or connection structures using rigid materials such as plastic to produce a friction fit engagement.

[0022] As further discussed herein, the various advantages and applications of such structures create numerous opportunities and benefits in a variety of industries. Additionally, in some embodiments, the structure may be configured to include lighting, plumbing, and / or other electrical or functional components that provide utility to a user.

[0023] Some embodiments of the system may include expandable members, such as tubes, cubes, rectangular prisms, or panels, that can be expanded using a liquid or gas (hereinafter collectively referred to as a "fluid") to move from a collapsed configuration to an expanded configuration. The expandable member can be coupled to one or more connectors and interconnected with one or more additional expandable members.

[0024] The expandable member can have a unique size, shape, color, stiffness or thickness to enable the expandable member to be used for a specific application. The expandable member can include an inlet port and a tubular portion or other three-dimensional shape, such as any type of geometric shape, including but not limited to a flat plate, a sphere, a cylinder, a cube, a pyramid, a geometric prism and / or other three-dimensional shape. The three-dimensional shape can be expanded via flow through the inlet port, causing the expandable member to unfold or move from a contracted configuration to an expanded configuration. Therefore, the three-dimensional shape of the expandable member can be used as or manifest as various different structures or features of a three-dimensional expansion structure, such as a wall, a support column, a visor, a roof, a tabletop, a bracket, a base or other various structural components.

[0025] In some embodiments, the expandable member may include two or more inlet ports, so that fluid communication between the inlet ports and the three-dimensional shape of the expandable member is possible. In this way, the expandable member can be interconnected with two or more connectors at the corresponding inlet ports to allow fluid passage through the three-dimensional shape, for example, to enable fluid communication with an additional expandable member connected to one of the connectors to which the expandable member itself is connected. Thus, multiple expandable members can be interconnected with each other in an end-to-end or array configuration to facilitate fluid communication between the connectors and the expandable members, so that a single expansion point of the structure can be used to expand all of the expandable members through fluid communication between them.

[0026] The connector(s) of the structure may include one or more connecting arms configured to couple to a corresponding expandable member.

[0027] For example, the connector may have a single connecting arm that may be coupled to the expandable member and, optionally, may be coupled to an inflation port to which an inflation device may be coupled for driving fluid through the connector and into the expandable member.

[0028] According to some embodiments, in addition to or as an alternative to an expansion device, the expansion port may be configured to couple to a connector arm of another connector.

[0029] In addition, in some embodiments, the connector may also include a plurality of connecting arms without expansion ports, so that the connector is only used to interconnect a plurality of expandable members. The connector may include a two-way, three-way, four-way, five-way, six-way or other multi-way connecting arm configurations so that a corresponding number of expandable members can be interconnected in a fluid communication manner. In this way, the connector can provide fluid communication between corresponding expandable members.

[0030] According to some embodiments, the connector can be configured to allow the connecting arm to rotate relative to the body of the connector. Based on the specific application or the shape of the structure formed, the connecting arm can be adjusted to an appropriate or desired orientation relative to the connector body. This articulation is particularly useful when the connector is used to interconnect multiple expandable members.

[0031] In some embodiments, the connecting arm of the connector can be configured to rotate or move up to 15 degrees relative to the first position of the connecting arm, up to 30 degrees relative to the first position of the connecting arm, up to 45 degrees relative to the first position of the connecting arm, up to 60 degrees relative to the first position of the connecting arm, up to 75 degrees relative to the first position of the connecting arm, or up to 90 degrees relative to the first position of the connecting arm.

[0032] Rotation of the connecting arms can allow the connecting arms to move or shift to a position where the multiple connecting arms are rotated so that the distal ends of the connecting arms are close together or converge toward each other, or in the opposite direction so that the distal ends of the connecting arms do not move toward each other or converge toward each other.

[0033] For example, in some embodiments, the connector may include a connector body having a flat or plate-shaped configuration and a plurality of connecting arms coupled around the periphery of the flat connector body. The connecting arms may rotate, turn or pivot together so that the connecting arms move together toward a single point and tend to converge with each other.

[0034] Optionally, one or more arms may also be configured to rotate in a direction opposite to the other connecting arms. This unique articulation of the connecting arms may allow the connector to define a portion of the structure corresponding to the connector as a generally concave shape, define a portion of the structure corresponding to the connector as a generally flat shape, or allow the connector to define a surface point that creates an intersection of diverging surfaces or a convergence of planes that are angled relative to each other.

[0048] The detailed description set forth below is intended to be a description of various configurations of the subject technology, rather than being intended to represent the only configuration that the subject technology can be put into practice. The accompanying drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details in order to provide a thorough understanding of the subject technology. However, it is apparent to those skilled in the art that the subject technology can be put into practice without these specific details. In some instances, known structures and components are shown in block diagram form to avoid blurring the conception of the subject technology. For ease of understanding, identical components are marked with identical element numbers.

[0049] Now referring to the accompanying drawings, Figures 1 to 24 Various aspects of the disclosed embodiments are shown. The features shown in these figures and discussed herein can be incorporated into various systems, various structures, and various components. The system can provide an expandable and retractable structure to provide a structure that can be temporarily and selectively expanded to an expanded configuration and folded to a stowed configuration when needed.

[0050] Now referring to the accompanying drawings, Figure 1 An example of one of many different three-dimensional shapes that can be manufactured using components of the structures discussed herein is shown. Figure 1 is an embodiment of an expandable structure 10 including a plurality of expandable members 12 and a connector 14 . Figure 1 and Figure 2 A perspective view and a side view are shown, respectively, of the structure 10. The structure 10 may have a three-dimensional design.

[0051] For example, the structure 10 may have a pentagonal base 16. However, other shapes may be employed, such as rectangular, square, hexagonal, triangular, or other polygonal shapes, with one or more interconnected expandable members 12 spanning the base to interconnect the sides of the base 16. Furthermore, the three-dimensional shape of the structure may be determined based on the intended application or other considerations, thereby providing a wide variety of shapes, sizes, and uses for the consumer.

[0052] like Figure 1 and Figure 2 As shown in the embodiment of the present invention, each connector 14 can connect up to five expandable members 12. In this way, the structure 10 can define a plurality of triangular faces 18, which are themselves defined by adjacent expandable members 12 around the exterior of the structure 10. Advantageously, when expanded, this design of the structure 10 can provide a substantially rigid and stiff structure utilizing a triangular framework. In this way, the structure 10 can be a stable structure, thereby being useful in a variety of applications.

[0053] The stability and integrity of structure 10 are examples of some of the performance and utility of the inflatable structures disclosed and taught herein through various examples and disclosures. In addition, structure 10 can not only provide a reliable and stable framework, but structure 10 can also enable the user to incorporate various optional features (such as lighting and shading components), as well as any of the various components and features described above.

[0054] Reference now Figures 3 to 10 , illustrates various features of a connector 14 that may be used with the structure 10. As shown, the connector 14 may include one or more connector arms 20 coupled to a body 22 of the connector 14.

[0055] According to some embodiments, connector 14 may be coupled to one or more expandable members 12. Connector 14 may also be used to interconnect two or more expandable members 12.

[0056] In some embodiments, the body 22 of the connector 14 can be configured to allow fluid communication between two expandable members 12 coupled to the connector 14. Thus, the connector 14 can facilitate fluid movement between one expandable member 12 and an adjacent expandable member 12, both coupled to the connector 14.

[0057] The body 22 may optionally include a material that allows one or more portions of the body to bend or flex. The body 22 may include flexible portions and rigid portions, such as a flexible interface to which the connector arm 20 may be coupled, and a flexible expansion port 80 to which an expansion mechanism may be coupled or to which other connector arms may be attached. In some embodiments, the expansion port 80 may bend or deflect to allow flexibility and adjustability similar to the ball joint of the connector arm 20, but with less complexity than a ball joint.

[0058] Furthermore, the body 22 itself may be flexible to allow relative movement between the interface and the connector arm 20. Thus, any expandable members coupled to the connector 14 may be allowed to flex or bend relative to each other.

[0059] In addition, the body 22 may include a cushioned or cushioned exterior or layer. Thus, if a user comes into contact with the connector during use, the cushioned body of the connector can advantageously provide some protection to prevent injury or trauma.

[0060] For example, the body 22 may include a rigid plastic or a mix of hard plastic and flexible and / or soft materials. For example, the connector arm 20 may include a generally spherical connection surface 52 that engages a generally spherical surface 54 of an interface 56 of the body 22. The interface 56 of the body 22 may be formed of a hard plastic or other rigid material. This may allow the ball joint to provide a secure interconnection between the connector arm 20 and the body 22 while also allowing the connector arm 20 to translate, rotate, pivot, or turn relative to the body 22.

[0061] The connector 14 can be formed of rigid and / or flexible materials. In some embodiments, the connector arm 20 can include a generally spherical connection surface 52 formed of a hard material (such as hard plastic) that mates with the hard plastic of the interface 56 of the body 22 .

[0062] Optionally, in some embodiments, a portion of the connector arm 20 (such as at least the middle length of the connector arm 20) may include a flexible material that allows the farthest position of the second end or distal end 72 of the connector arm 20 to deflect relative to the spherical connection surface 52 of the connector arm 20.

[0063] The connector arm 20 can optionally be configured to define a longitudinal length or extent between the spherical connection surface 52 and the distal end 72. In some embodiments in which a portion of the connector arm 20 is formed from a flexible material, the connector arm 20 can be manipulated or bent to a desired angular orientation to provide increased flexibility and alternative configurations, as well as the benefit of ease of assembly, which can be reflected by allowing slight adjustability when the connector arm 20 is connected to another component (such as another connector or an expandable member).

[0064] Connector 14 may include only hard connector arms, only soft connector arms, or a mixture of hard and soft connector arms. The connector may be configured to allow a user to interchange connector arms at will, so as to allow a user to customize a given system based on the structure, function or other requirements of the connector arms.

[0065] Additionally, in some embodiments, the connector arm 20 can be formed as a single continuous piece with the body 22 of the connector 14 (i.e., the connector arm is formed integrally with the body). In this way, the body can be continuously formed with one or more connector arms, and each connector arm defines a predetermined orientation relative to the body. In such embodiments, the connector arm can include a flexible portion that allows the connector arm to bend or pivot relative to the body so as to provide some adjustability of the connector arm relative to the body. Thus, such embodiments can allow the connector to have one or more deflectable or adjustable connector arms without using a ball joint or other articulated connection between the body and the connector arm, but rather providing a single-part connector in which the body and (multiple) connector arms are formed from a single continuous material. However, in addition to connector arms that are formed integrally with the body, such embodiments can also be configured to include one or more interfaces or joints to which separately formed connector arms can be coupled.

[0066] In some embodiments, the connector arm 20 can be coupled to the body 22 to allow the connector arm 20 to move relative to the body 22. Such movement can cause the connector arm 20 to translate, rotate, pivot, or rotate relative to the body 22.

[0067] like Figures 3 to 6 As shown, the connector arm 20 can be moved relative to the body 22 to a plurality of positions. Figure 3 A top perspective view of the connector 14 is shown with the connector arm 20 in the downwardly bent position 30. The downwardly bent position 30 may represent a farthest position of the second or distal end 72 of the connector arm 20 relative to the body 22.

[0068] Figure 4 The connector arm 20 is shown in an upwardly bent position 32. The upwardly bent position 32 may represent an opposite position relative to the downwardly bent position 30. The connector arm 20 may rotate, turn, or pivot up to about 90 degrees or more when moving between the downwardly bent position 32 and the upwardly bent position 32. The range of motion of the connector arm 20 relative to the body 22 may be up to about 15 degrees, up to about 30 degrees, up to about 45 degrees, up to about 60 degrees, up to about 75 degrees, up to about 90 degrees, up to about 105 degrees, or more.

[0069] When measuring the range of motion of a given connector arm 20, the body 22 of the connector 14 can define a plane 40 passing through the body 22 and the connector arm 20. Figure 5 and Figure 6 As shown, the central axis 42 of the connector arm 20 can be at an offset angle relative to the connector plane 40. For example, Figure 5 In FIG. 4 , the central axis 42 of the connector arm 36 defines a downward angle 44 relative to the plane 40. In addition, in Figure 6 14 , the connector arm 20 is rotated to the upwardly bent position 32 to define an upward angle 46 between a central axis 42 of the connector arm 20 and a plane 40 of the body 22 of the connector 14 .

[0070] According to some embodiments, downward angle 44 can be in the range of 0 to about 15, about 0 to about 30, about 0 to about 45, about 0 to about 60, about 0 to about 75, or more. Similarly, upward angle 46 can be in the range of about 0 to about 15, about 0 to about 30, about 0 to about 45, about 0 to about 60, about 0 to about 75, or more.

[0071] like Figure 5 and Figure 6 As shown, the connector arm 20 can be coupled to the body 22 using a ball-and-socket configuration 50. For example, the connector arm 20 can include a generally spherical connection surface 52 that engages a generally spherical surface 54 of an interface 56 of the body 22. It will be appreciated by those skilled in the art that such a ball-and-socket configuration 50 enables the connector arm 20 to be in fluid communication with the inner cavity 60 of the body 22.

[0072] In some embodiments, the connector arm 20 can define an internal passage 62 extending from a first end 70 to a second or distal end 72 of the connector arm 20. The first end 70 of the internal passage 62 of the connector arm 20 can be open to the internal cavity 60 of the body 22. The internal cavity 60 can be in fluid communication with one or more interfaces 56 to allow one or more connector arms 20 to be in fluid communication with the body 22 and / or the connector arms 20 to be in fluid communication with each other.

[0073] Reference again Figure 3 and Figure 4 , the body 22 may include an expansion port 80 in fluid communication with the lumen 60 of the body 22. The expansion port 80 may be used to couple an expansion device (not shown) so that a user may drive fluid into the lumen 60 of the body 22 to expand any fluid-connected connector arms 20 and expandable members respectively coupled to the expansion port.

[0074] Thus, the connector 14 may optionally include an inflation port 80 that allows the connector 14 to be used to drive fluid toward one or more expandable members 12. However, in some embodiments, the connector 14 may be designed without an inflation port 80. In such embodiments, the connector 14 may provide fluid communication between or among all expandable members that are respectively coupled to the connector 14.

[0075] In other embodiments, the connector 14 can be configured to block or prevent fluid flow to or from one or more expandable members coupled to the connector 14. For example, the connector 14 can be configured to have a solid body 22 that does not provide any fluid communication between the respective coupled expandable members 12. However, the connector 14 can also be configured such that the body 22 allows fluid communication between two or more expandable members and prevents fluid communication to or from one or more other expandable members.

[0076] As described above, the inflatable structures and / or connectors of the systems disclosed herein may be formed to include one or more valve features to selectively allow or restrict fluid communication through the inflatable structures and / or connectors.

[0077] In some embodiments, the connector may have one or more valves that control the flow of fluid therethrough.

[0078] In some embodiments, the inflatable structure(s) may have one or more valves that control the flow of fluid therethrough.

[0079] Additionally, in some embodiments, neither the connector nor the expandable structure(s) have one or more valves to control the flow of fluid therethrough.

[0080] Additionally, in some embodiments, the connector and the expandable structure(s) may each have one or more valves that control the flow of fluid therethrough.

[0081] If used in some embodiments of the system, the valve may be opened and / or closed manually by a user and / or through interaction with the expandable member or connector to allow fluid communication between the expandable structure and the connector.

[0082] For example, the connector 14 can be configured to include a valve (e.g., a one-way valve) at one or more interfaces 56 or in the connector arm 20. According to some embodiments, a one-way valve can be incorporated into the internal channel 62 of each connector arm 20. The one-way valve can allow fluid to flow into or out of the connector arm 20.

[0083] For example, the connector arm 20 can be configured to allow fluid to flow through the internal channel 62 of the connector arm 20 only when the connector arm 20 is interconnected with the corresponding expandable member 12.

[0084] like Figure 5 and Figure 6As shown, the connector arm 20 may include one or more engagement forks 90 along the second end 72 of the connector arm 20. The engagement forks 90 may extend distally from the second end 72. However, the engagement forks 90 may also be positioned around the periphery or periphery of the connector arm 20 in a manner that enables proper interconnection with the corresponding expandable member 12. Various designs and configurations that allow for engagement between the connector arm 20 and the expandable member 12 may be implemented.

[0085] Optionally, upon engagement between the connector arm 20 and the expandable member 12, the one-way valve of the connector arm 20 can be disengaged, thereby allowing flow through the interior passage 62 of the connector arm 20 and the expandable member 12. A grub or connection device can be coupled to the connector arm 20 or the expandable member 12 and configured to access and / or open the valve when the connector arm is coupled to another connector arm or the expandable member.

[0086] Some embodiments may be configured to include a valve in the connector arm 20 that may allow flow out of the connector 14 into the expandable member 12, but also generally prevent flow from the expandable member 12 to the connector 14. Such a design may be useful for a given expansion connector coupled with an expansion device for driving fluid into the structure 10. However, such an expansion connector may also include a single one-way valve incorporated into the expansion port 80 in lieu of or in addition to other one-way valves incorporated into the connector arm 20 or body 22 of the connector 14.

[0087] The connector arms of the connector may be configured to couple to a corresponding expandable member. The coupling between the expandable member and the connector arms enables or provides a secure interconnection between the expandable member and the connector.

[0088] For example, now refer to Figures 7 to 10 , showing the relationship between the connector 14 and the expandable member 12 in different views. Figure 7 As shown, the connector 14 can be connected to the expandable member 12 at the first end 100 of the expandable member. The first end 100 may include a connection interface 102, and the second end 72 of the connector arm 20 can be inserted into the connection interface 102. As described above, the second end 72 of the connector arm 20 can be engaged and fixedly connected to the expandable member 12. The connection interface 102 may include corresponding engagement features, such as forks, pawls, grooves or other such features, which can engage with the connector arm 20 and ensure a secure connection between the connector arm 20 and the connection interface 102.

[0089] In some embodiments, the system can be configured such that the joint between the connector arm 20 and the connection interface 102 provides a substantially rigid connection. The system can be configured to preferentially allow the expandable member 12 to flex (to support any significant bending stresses or other loads imposed on the structure in the area surrounding a given connector and expandable member(s)) without allowing the joint itself to potentially act as a structural failure point.

[0090] For example, in some embodiments, Figures 7 to 10 It is shown that a substantially rigid interconnection can be provided by a secure, deep engagement between the second end 72 of the connector arm 36 and the connection interface 102. For example, in some embodiments, about 1 / 3 to 1 / 2 of the length of the connector arm 20 can be inserted into the connection interface 102 or longitudinally overlapped with the connection interface 102 to be securely coupled to the connection interface 102. Additionally, in some embodiments, about 1 / 3 to 2 / 3 of the length of the connector arm 20 can be coupled to the connection interface 102. Advantageously, at least about 1 / 3 or at least about 1 / 2 of the length of the connector arm 20 can be inserted into the connection interface 102 or longitudinally overlapped with the connection interface 102 to form a high-quality rigid joint that exhibits high bending strength. Fig.10 A cross-sectional view of the wall of the expandable member 12 is shown to reveal the connection interface 102 from within the tubular member 12 .

[0091] also, Figures 7 to 9 An embodiment of a manifold 110 is shown for use with the connector body 22. The manifold 110 may include a plurality of hollow passages 112 interconnected with the interface 56 of the body 22 to allow fluid communication between the connector arm 20 and any expandable member 12 coupled thereto.

[0092] Optionally, the connector 14 can include an end cap 120 that can be coupled to the second end 72 of the connector arm 20. In some embodiments, the end cap 120 can be secured to the connector arm 20 and prevent air from flowing out of the connector arm 20. According to some embodiments, the end cap 120 can also provide protection and / or prevent the ingress of debris at the second end 72 of the connector arm 20. In particular, the end cap 120 can protect the engagement prong 90 and help ensure that the second end 72 of the connector arm 20 remains clean and free from debris or other particles.

[0093] In some embodiments where the valve is incorporated into the connector arm 20 itself, the end cap 120 can also be used to prevent flow through the connector arm 20. However, either of these two components (the valve of the connector arm 20 (when used in the design) and the end cap 120) can contribute and tend to ensure that the fluid pressure in the system is not compromised and remains at a desired level during use of the system 10.

[0094] Likewise Figures 7 to 10 As shown, the ball joint 50 of the connector 14 can allow the connector arm 20 to rotate, turn, or pivot to a plurality of different positions, thereby moving up and down or left and right relative to a given structure or plane of the connector 14. In some embodiments, the interconnection of the connector arm 20 and the body 22 of the connector 14 can allow for rotational articulation to enable a variety of unique configurations and positions of the connector arm 20, thereby allowing the shape of the structure 10 to be specifically articulated to a given design.

[0095] As previously mentioned, the connector may be configured to include multiple connector arms, arranged in different shapes or configurations, and to provide other structural or functional features for a particular application. Figures 11 to 18 , Fig.23 and Fig.24 Various views of alternative connector designs that may be used in accordance with some embodiments of the structures disclosed herein are shown. The connector designs shown and described in this disclosure may be modified and / or used in any combination. For example, in accordance with certain embodiments, Figures 1 to 18 , Fig.23 and Fig.24 Any of the connector designs may be combined with one another or used individually in a given structure or set of structures.

[0096] Figures 11 to 13 An embodiment of a connector 140 is shown in which the connector 140 includes a connector body 142 having a plurality of connection interfaces 144 in which a connector arm structure 146 may be mounted. The connector body 142 may include an expansion port 150 that may be coupled to an expansion device and / or a connector arm of another connector of the structure. The connector arm structure 146 may function in a manner similar to the ball and socket connector arm of the connector 14 discussed above. However, as Fig.13 As shown, the connector arm structure 146 can provide a rotational range of motion that is approximately symmetrical about the connection axis 160. In this way, the connector arm 162 of the connector arm structure 146 can be rotated, turned or pivoted to a desired position about the connection axis relative to the body 142 of the connector 140.

[0097] Figures 11 to 13 The illustrated connector 140 also illustrates that the connector may include three connector arms extending therefrom. In this regard, Figures 14 to 18 Similar alternative embodiments of connectors are shown. For example, Figures 14 to 16 A connector 170 is shown having a connector body 172 including four interfaces 174 to which corresponding connecting arm structures 176 are coupled.

[0098] also, Fig.17 and Fig.18 Another embodiment of a connector 190 is shown having a connector body 192 including two interfaces 194 to which corresponding connecting arm structures 196 are coupled. Additional embodiments of connectors 170, 190 may also include corresponding expansion ports and other structural and functional features as disclosed herein for other embodiments.

[0099] In addition, as with connector 14, Figures 11 to 18 The illustrated connector may also include a flexible body and / or a cushioned body.

[0100] therefore, Figures 11 to 18 The connector body shown can be flexible to allow relative movement between the interface and the connector arm. This can allow any expandable members coupled to the connector to flex or bend relative to each other.

[0101] also, Figures 11 to 18 The connector body shown may include a cushioned or cushioned exterior or cushioning layer. Thus, if a user contacts the connector during use (e.g., during deflation of the structure), the cushioned body of the connector can advantageously provide some protection to prevent injury or trauma.

[0102] The connectors disclosed herein show a variety of connector bodies with interfaces that allow the connector arms to have a default or initial position in which the connector arm axes are located in a common plane. However, the connector body can also be configured to allow the connector arm axes to be disposed at approximately a 90 degree angle relative to one or more other connector axes of the connector.

[0103] In some embodiments, the connector can be configured to have multiple connector arms extending from a single point. For example, the connector can be configured as a six-arm connector, where all arms are at 90 degree angles relative to each other. Other connectors can be configured to have other angular relationships between the arms. Some connectors can be configured with connector arms extending from multiple points (not just a single point). Such embodiments can implement any of the features and structural characteristics disclosed herein.

[0104] As described above, the connectors disclosed herein may be used to form a variety of structures; however, the teachings and disclosures herein provide examples of connector bodies and other features that may be implemented to produce any of a variety of useful structures suitable for educational, entertainment, and commercial applications.

[0105] Reference now Fig.19 and Fig. 20 , showing the expansion and configuration of structure 200. Fig.19 The structure 200 is shown in an unexpanded or collapsed configuration, while Fig. 20 The structure 200 is shown in an expanded configuration. As shown, an expansion device 202 can be coupled to a connector 204 of the structure 200. The expansion device 202 can direct air into the connector 204 so that the air can be transferred to the expandable member 206 of the system. Fig. 20 As shown, the expandable member will be pressurized and achieve a rigid or expanded configuration. Structure 200 utilizes a pyramidal design using a connector having at least three connecting arms.

[0106] Fig.21 and Fig. 22 Another embodiment of an expandable assembly 210 according to some embodiments is shown having a plurality of expandable members 212 coupled together via a connector 220 and a valve component 222. The connector 220 can include five connection ports 224 distributed around the perimeter of a connector body 226. The connector ports 224 can be oriented coplanar with respect to each other in the plane of the body, but extend in different directions away from a center point of the connector body 226. Furthermore, one or more additional connector ports can extend from the connector body 226 in a plane different from the plane of the body.

[0107] The valve component 222 may include a membrane or a sealing portion that can be deflected to an open position when a corresponding protrusion of the male valve portion is pressed against the membrane or the sealing portion. The valve component 222 can be coupled, connected, integrated, or otherwise formed with the expandable member 212 or the connector 220. The male valve portion can also be coupled, connected, integrated, or otherwise formed with the expandable member 212 or the connector 220. The valve component 222 can be coupled to the expandable member 212 and / or the port 224 via a friction fit or a mechanical fit (such as a threaded connection).

[0108] therefore, Fig.21 and Fig. 22 The illustrated assembly 210 illustrates that the connector may include one or more ports extending in a single plane and one or more ports extending in another plane transverse to the plane of the other ports. As discussed above with respect to other embodiments disclosed and illustrated herein, the connector 220 may incorporate any of a variety of features, such as valves, covers, rigid and / or flexible connector arm structures, connector arms integrally formed with or separately formed from the connector body, etc., which features will not be repeated for the sake of brevity, but are incorporated herein by reference.

[0109] Fig.23 and Fig.24Another embodiment of an expandable assembly 250 is shown having a plurality of expandable members 252 that may be coupled together via a connector 260 and a connector arm 262 in accordance with some embodiments. Fig.23 A pair of expandable members 252 are shown interconnected with a connector 260 via connector arms 262 .

[0110] like Fig.23 As shown, the connector arms 262 can be detached and attached to the connector 260. Each connector arm 262 can be received within a port 264 of a body 266 of the connector 260. Each connector arm 262 can include a central protruding area 270 between opposing first and second ends 272, 274 of the connector arm 262. Although the connector arms 262 are shown with diametrically opposed ends 272, 274, the ends can also be oriented at angles such as 45 degrees, 60 degrees, or 90 degrees. Other angular orientations of the ends relative to each other or relative to the central protruding area 270 can also be achieved.

[0111] In addition, the first end 272 and the second end 274 of the connector arm 262 can each include one or more engagement members 276. The engagement member 276 (e.g., a deflectable fork) can be inserted into the port 264 of the connector 260 and facilitate engagement with the port 264. In addition, the engagement member 276 can be inserted into the connection interface 280 of the (multiple) expandable member to facilitate engagement with the connection interface 280. Therefore, the first end 272 and the second end 274 can be connected to the expandable member 252 and / or the port 264 via a friction fit (e.g., using the engagement member 276) or a mechanical fit, such as a threaded connection (not shown, but can include corresponding male and female threads on the corresponding first end 272 and second end 274, the expandable member 252 and / or the port 264).

[0112] Furthermore, in some embodiments, the engagement member 276 may be inserted into the connection interface 280 to open the valve 278 of the connector 260. For example, the valve 278 of the connector 260 may be disposed at each port 264 of the connector 260, and the valve 278 may open when engaged with the connector arm 262. When the connector arm 262 is removed from the connection interface 280, the valve 278 may automatically return to its closed position.

[0113] The connection interface 280 can be at least partially recessed into the end of the expandable member.In addition, the connection interface 280 can include a rigid edge or collar 282 that can be used to facilitate gripping and engagement with the connector arm 262.

[0114] Additionally, the ends of the expandable member 252 can be formed to be rigid or flexible. In some embodiments, the connection interface 280 can include a rigid material and be recessed within the ends of the expandable member.

[0115] Fig.24 It is also shown that the connector arm 262 can be interference fit into the port 264 of the connector 260.

[0116] Similar to the discussion above with respect to other embodiments, the body 266 of the connector 260 can be flexible to allow the ports 264 of the body 266 to bend or flex relative to each other. In addition, the body 266 can include a cushioned or cushioned exterior or layer. Thus, if a user contacts the connector during use, the cushioned body of the connector can advantageously provide some protection from injury or trauma.

[0117] Furthermore, according to some embodiments, connector arm 262 may advantageously be formed as a rigid member. Thus, connector arm 262 may be interconnected with port 264 of body 266, which in some embodiments may be relatively flexible and pliable. Furthermore, if a portion of assembly 250 is broken or damaged, it may be easier and less expensive to replace only connector arm 262, rather than replacing port 264 of body 266 or some other component integrally formed with the expandable member or connector.
