DETAILED DESCRIPTION

(12) Reference throughout this specification to one embodiment, an embodiment, or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Appearances of the phrases in one embodiment, in an embodiment, and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment. Similarly, the use of the term implementation means an implementation having a particular feature, structure, or characteristic described in connection with one or more embodiments of the present disclosure, however, absent an express correlation to indicate otherwise, an implementation may be associated with one or more embodiments.

(13) FIG. 1A is a perspective view of a connection apparatus 100, according to one embodiment. The connection apparatus 100 includes a hollow connector sleeve 110 and at least one interlockable component 120. Generally, the purpose of the connection apparatus 100 of the present disclosure is to enable a user to quickly and efficiently connect various components together in a secure yet detachable configuration. In one embodiment, the hollow connector sleeve 110 circumscribes a portion of a support shaft (described below) and includes interlockable components 120 that can engage complementary interlockable components on an attachment, thus allowing the support shaft and the attachment to securely (yet detachably) connect to each other.

(14) For example, wooden beams may be securely held together using various embodiments of the connection apparatus 100. In one embodiment, a wooden beam with a rectangular cross-section (e.g., a 24) may be inserted into a hollow connector sleeve 110 and a subsequent wooden beam with a square cross-section (e.g., a 44) may also be inserted into a second connector sleeve. Using the complementary interlockable components on the two connector sleeves, the wooden beams can be easily connected to one another. The two wooden beams may be repeatedly attached and detached in applications where the structure is temporary. For example, trade fair booths, temporary fencing lines, tents, scaffolding, and fair equipment, among others, are potential applications for the secure yet detachable design of the connection apparatus 100. While the connection apparatus 100 provides the flexibility to easily construct and deconstruct a structure, it is also contemplated that the connection apparatus 100 of the present disclosure may also be used in permanent applications, such as home construction projects. For additional examples on how the connection apparatus 100 of the present disclosure can be implemented, see the description below with reference to FIG. 5.

(15) Details regarding the hollow connector sleeve 110, the interlockable components 120, the attachments, and the various other elements of the connection apparatus 100 and system are included below with reference to FIGS. 2A-5. Also, FIG. 1A shows the interior surfaces 112 of the hollow connector sleeve 110 and the exterior mounting panels 114 of the hollow connector sleeve 110. Additionally, FIG. 1A shows multiple anchoring mechanisms 116 that are described in greater detail below. Also, FIG. 1A shows two viewpoints: Viewpoint B is the view from which FIG. 1B is depicted and Viewpoint C is the view from which FIG. 1C is depicted.

(16) FIG. 1B is a top view (from Viewpoint B in FIG. 1A) of the connection apparatus 100 depicted in FIG. 1A, according to one embodiment. The connection apparatus 100 may be constructed from any durable material that is capable of withstanding the forces/loads of the anticipated application. In one embodiment, the connection apparatus 100 is constructed of a glass-filled nylon material. In another embodiment, the connection apparatus 100 is constructed of polymer composites, plastic, wood, or metal. Also, the connection apparatus 100 may be one integral element or it may be constructed from various elements. For example, in one embodiment (not depicted) the hollow connector sleeve 110 includes halves that can be connected together about an existing support shaft. In such embodiments, the connection apparatus 100 can be used to modify or retrofit existing (e.g., permanent) structures. With regards to retrofitting, it is also contemplated that the interlockable components 120 may also be modular in that the interlockable components 120 themselves may also be removable/replaceable. In other words, default interlockable components 120 can be disconnected from the hollow connector sleeve 110 and replaced with alternate interlockable components 120 in order to satisfy the specifics of a given application. When the connection apparatus 100 is made from a polymeric material, the apparatus 100 may be fabricated using conventional injection molding or extruding processes. In other embodiments, the connection apparatus 100 may be welded or soldered together.

(17) As depicted in FIG. 1B, the cross-sectional shape of the hollow connector sleeve 110 may be rectangular in order to fit over/circumscribe rectangular shafts. In other embodiments, depending on the specifics of a given application, the hollow connector sleeve 110 may have a circular, square, hexagonal, or other cross-sectional shape. Additional details regarding an embodiment with a cylindrical (circular cross-section) are included below with reference to FIG. 4. The interior surface(s) 112 of the hollow connector sleeve 110 may include components for preventing the support shaft (beam or element about which the apparatus 100 is connected) from slipping. For example, in certain embodiments the interior surface 112 may include grooves or compression channels that prevent the support shaft from slipping through the hollow connector sleeve 110. In other embodiments, the interior surfaces 112 of the hollow connector sleeve 110 may be coated with a non-slip material to further promote a good fit between the support shaft and the connection apparatus 100. These non-slip, interior surface features may be implemented independent of the anchoring mechanism 116 (described below in greater detail with reference to FIG. 1C) or may be used in conjunction with the anchoring mechanism to further provide stability between the support shaft and the connection apparatus 100.

(18) The interlockable components 120, as described below in greater detail, are disposed on the exterior mounting panels 114. The interlockable components 120 may be integrated with the hollow connector sleeve 110 or may be affixed (i.e., welded or otherwise permanently bonded/attached) to the exterior mounting panels 114. Throughout the present disclosure, the term exterior mounting panels 114 refer to the exterior surfaces of the hollow connector sleeve 110 that have interlockable components protruding therefrom. The exterior surfaces, or at least the portions of the exterior surface, that do not have a protruding interlockable component, are labeled as the non-attaching panels 115 throughout the present disclosure. For example, the embodiment of the connection apparatus 100 depicted in FIG. 1B includes three exterior mounting panels 114 and one non-attaching panel 115. The designation of one side as a non-attaching panel 115 does not preclude that side from being affixed or attached to another component; the designation only means that interlockable components 120 are not included on that side of the hollow connector sleeve 110. Additional details regarding the interlockable components 120 are included below with reference to FIG. 2B.

(19) FIG. 1C is a side view (from viewpoint C in FIG. 1A) of the connection apparatus 100 depicted in FIG. 1A, but with a support shaft 150 extending through the connection apparatus 100, according to one embodiment. As mentioned above, the support shaft 150 is the element, pole, rod, or beam that extends through the hollow connector sleeve 110. In some embodiments, the support shaft 150 may not completely extend through the hollow connector sleeve 110 but instead may abut up to another support shaft 150. In other words, the hollow connector sleeve 110 may also function as a coupling component for connecting two support shafts 150 together. Also, in one embodiment, the connection apparatus 100 may be an end cap that fits over the end of a support shaft 150 and thus the hollow connector sleeve 110 may have 5 sides (instead of the four side walls depicted in the Figures).

(20) Also depicted in FIG. 1C are the anchoring mechanisms 116. The hollow connector sleeve 110 may be formed from two semi-sleeves 110a, 11b that can be affixed together around the at least one support shaft 150 and the hollow connector sleeve may include at least one anchoring mechanism for anchoring the hollow connector sleeve 110 to the at least one support shaft 150. As briefly described above, the anchoring mechanisms 116 may be implemented independent of or in conjunction with the interior surface features or materials in order to prevent the support shaft from slipping with respect to the connection apparatus 100. The anchoring mechanism 116, in one embodiment, includes multiple holes in the hollow connector sleeve 110 through which nails or screws may be driven to secure the shafts 150 position with respect to the hollow connector sleeve 110. In other embodiments (not depicted), the anchoring mechanism may include straps, clamps, fasteners, bolt assemblies, etc., for securing the hollow connector sleeve 110 about the support shaft 150.

(21) FIG. 2A is a top view of a connection apparatus 200 with various attachments 236, 237, 238 and a support shaft 250, according to one embodiment. The attachments 236, 237, 238 include complementary interlockable components that engage the interlockable component(s) 220 affixed to the exterior mounting panels 214 of the hollow connector sleeve 210. In one embodiment, one of the attachments may include a second connection apparatus 237 that circumscribes a second support shaft 252. In one embodiment (as depicted), the hollow connection sleeve 210 may have an exterior mounting panel 214 that has three separate interlockable components 220. Depending on the specific application, an attachment 236 may span across multiple interlockable components due to the force/load that is anticipated on such a component while other attachments 238 may only engage a single interlockable component 220, thereby leaving space for additional attachments to be connected. In other words, an exterior mounting panel 214 of the hollow connector sleeve 210 may include, for example, three interlockable components: a primary central protruding flange and two secondary protruding flanges. In one embodiment, the central protruding flange may be comparatively larger (wider, longer, etc) than the secondary protruding flanges. Certain attachments may have a single female associated interlockable component that receives/interlocks with the primary protruding flange. Other attachments may have a single female associated interlockable component that receives/interlocks with one of the two secondary protruding flanges. Other attachments may have a single female slot that receives all three protruding flanges or three separate female slots that each receives one of the three protruding flanges.

(22) The attachments may include features or elements that are useful for a specific application or purpose. For example, an attachment may include another hollow connection sleeve, a hook, a magnetic coupling, a bolt assembly, a hinge, a rotating bearing, a pivoting bearing, a sliding bearing, an electrical conduit support, an electrical box, an electrical fixture, Velcro member, a clamp, a strap, etc. These features may not require a separate/independent attachment but instead may be auxiliary features mounted on an existing attachment or on the connection apparatus 200 itself. For example, a hook or a hinge assembly may not be connected to the hollow connector sleeve 210 via the interlockable components but instead the hook or hinge assembly may be attached to the hollow connector sleeve 200 or to an attachment via some other mechanism (welding, bonding, permanently affixed). The feature may be integrated with the connection apparatus 200 or may be affixed via bonding, welding, bolts, clamps, screws, etc. Thus, the features listed above, as well as any additional features/elements, may be implemented in conjunction with the connection apparatus 200 as attachments coupled via the interlockable components 220, or as auxiliary features, mounted/affixed to the connection apparatus 200 without using the interlockable components 220.

(23) FIG. 2B is a cross-sectional view of the connection apparatus 200 depicted in FIG. 2A, according to one embodiment. The interlockable components may be configured in various forms. The embodiment shown throughout the figures, depicting a protruding male flange 222 that extends outward from an end of a shaft 223 that is distal from an exterior mounting panel 214 and a complementary recessed female slot 224 of the attachment 236, is only illustrative of one example of the interlockable components. It is contemplated that other configurations, such as an interlocking teeth, interlocking dovetails, interlocking hooks, and other complementary sets of protrusions and recessions, fall within the scope of the present disclosure. Additionally, the number, size, dimensions, and angled configuration of the interlockable components depicted in the figures are not intended to limit the scope of the present disclosure. Thus, the exterior mounting panel 214 may include a single interlockable component or may include multiple interlockable components to provide flexibility in arranging the attachments 236, 237, 238. Also, the male flanges 222 may be affixed to the attachments and the recessed female slots 224 may be affixed to the connection apparatus 200 (vice-versa as depicted). Also, as described above, the interlockable components 220 themselves may be removable so that a user can switch out the configuration of interlockable components 220 depending on the specifics of a given application.

(24) FIG. 3A is a perspective view of a connection apparatus 300 with various attachments 330, according to one embodiment. As described above, the attachments 331, 332, 333, 334 (collectively 330) may include a variety of elements. As depicted and according to one embodiment, one of the attachments may include a member 331 that can encompass the tip of an additional support shaft, thus extending the additional support shaft in a direction perpendicular to the support shaft (not depicted) circumscribed by the connection apparatus 300. In another embodiment, an attachment may include a member 334 that is configured to engage an additional support shaft with larger dimensions than the original support shaft. Further, the attachments may include angled members 332, 333 that pitch/tilt an additional support shaft in skewed and/or non-perpendicular directions relative to the original support shaft. FIG. 3B is a top view of the connection apparatus 300 depicted in FIG. 3A, according to one embodiment. As described above, the attachments 330 may be configured to extend and angle the additional support shafts in a variety of directions, according to the specifics of a given application. The connection apparatus 300 may further include a cap 340.

(25) In one embodiment, the female slot 324 of the attachment 333 includes an open end 325 and a closed end 326. The attachment 333 may be positioned so that the open end 325 is configured to slidably receive one of the male protrusions 322 of the hollow connector sleeve 310. The protrusion 322 may be inserted within the female slot 324 until the protrusion 322 engages/contacts the closed end 326 of the female slot 324. In one embodiment, the connection apparatus 300 may further include fastener or securing features that facilitate maintaining a strong interlock connection between the connection apparatus 300 and the attachment 333.

(26) FIG. 4 is a perspective view of a cylindrical connection apparatus 400, according to one embodiment. The depicted embodiment of the connection apparatus 400 includes a hollow connector sleeve 410 that has an interior surface 412 and one exterior mounting panel 414 with the affixed interlockable components 420. The interior surface 412 has a circular cross-section for circumscribing cylindrical support shafts (not depicted). The non-attaching panel 415 is the curved exterior surface that has no panels for connecting attachments 430. Coupled to the interlockable components 420 is an curved attachment member 430 that extends an additional support shaft (not depicted) in an angled direction. The depicted connection apparatus 400 may also have an anchoring mechanism 416 for securing the apparatus 400 about the cylindrical support shaft. The anchoring mechanism may be a clamping mechanism that can be tightened to compress around the cylindrical support shaft. The depicted embodiment also shows that the exterior surfaces of the connection apparatus 400 may have a different shape than the interior surfaces 412. In other words, the apparatus may have an internal rectangular cross-section, as previously depicted in FIGS. 1A-3B, but the exterior surfaces (i.e., the exterior mounting panels 414) may have a different shape, such as a circle, rectangle, trapezoid, or others, according to the specifics of a given application.

(27) FIG. 5 is a schematic block diagram of a structure system implementing various components of the present disclosure, include multiple connection apparatus' 500, attachments 530, and support shafts 550, according to one embodiment. The structure, which may be scaffolding or a tent/booth frame, represents an example of the various connections that can be made using multiple connection apparatus' 500 of the present disclosure. The first connection apparatus 500A circumscribes two abutting, vertical support shafts 550A, 550B and couples them together. This first connection apparatus 500A also includes interlocking components (not depicted) that engage an attachment that extends another support shaft 550C horizontally. This horizontal support shaft 550C is coupled with another horizontal support shaft 550D via another connection apparatus 500B. This connection apparatus 500B includes a pivoting attachment 530F (e.g., light fixture) that allows an element to swivel about the connection apparatus 500B. Further, this connection apparatus 500b also includes interlockable components (not depicted) that engage attachments 530A, 530B, 530C. Two of the attachments 530A, 530C are configured to extend support shafts 550F and 550G in angled directions. These support shafts 550F, 550G may actually be ropes, cables, or other non-rigid elements for providing additional support to the central connection apparatus 500B. On the other end of support shaft 550D is yet another connection apparatus 500C that is circumscribing a portion of another support shaft 550E. On the tops ends of support shafts 550E and 550A, two more connection apparatus' 500E, 500D are affixed. These connection apparatus' 500E, 500D include corresponding angled attachments 530D, 530E that receive the opposite end of the angled support shafts 550F, 550G. The depicted structure is illustrative of the many different configurations that are possible with the connection apparatus 500 of the present disclosure.

(28) FIG. 6 is a schematic flowchart diagram of one embodiment of a method 600 for coupling a support shaft to an attachment. The method includes positioning 602 a hollow connector sleeve around a support shaft, with the hollow connector sleeve having at least one anchoring mechanism and at least one exterior mounting panel that has at least one interlockable component. The method further includes securing 604 the hollow connector sleeve around the support shaft using the anchoring mechanism and coupling 606 coupling the attachment to the hollow connector sleeve, the attachment having at least one corresponding interlockable component that is detachably coupleable with the at least one interlockable component.
