Description

[0001] This disclosure relates to a connector assembly. Background Technology

[0002] Structural components and / or parts are typically required to be connected together to form a rigid and / or robust structure.

[0003] Traditionally, columns and railings are joined by welding to provide a secure and rigid connection. However, assembling or disassembling welded structures is not only time-consuming but also requires skilled workers and specialized equipment. After disassembly, the individual components of the structure are not easily reused because they require preparation (e.g., machining), resulting in material loss and a significant investment of time.

[0004] It is known that fittings or connectors are used to connect structural components together, allowing the structure to be disassembled and reused. Personnel responsible for assembling or disassembling the structure must not only handle the connector parts, their fixing components (e.g., screws or bolts), and the structural components, but also hold and manipulate tools to operate on the fixing components. This process is cumbersome, time-consuming, and frustrating, and if the structural components are not properly aligned during assembly, it can lead to unsafe connections. To reduce errors and improve user safety, it is common practice to have two people work together. Furthermore, fixing components often become lost and / or damaged over time, which can be frustrating in terms of connector reuse.

[0005] Therefore, there is a great need for a reusable connector that securely connects structural components and allows a single user to quickly connect and disconnect structural components. Summary of the Invention

[0006] According to this disclosure, an apparatus as set forth in the appended claims is provided. Other features of the invention will be apparent from the dependent claims and the following description.

[0007] Therefore, a connector assembly (10, 12, 14) for engaging with a first member (100) is provided, wherein the first member (100) is composed of a cavity (102) having a contact surface (104) and an opening (106) leading to the cavity (102).

[0008] Connector assemblies (10, 12, 14) may include a core element (300) having an outer engagement surface (302) extending from a leading edge end (310) toward a trailing edge end (312). The connector assemblies (10, 12, 14) may include an engagement sleeve (400) extending from the leading edge end (410) to the trailing edge end (412), the engagement sleeve (400) being formed by a channel (402) having a central axis (450), wherein the engagement sleeve channel (402) has an opening (406) at the trailing edge end (412). The engagement sleeve opening (406) and the engagement sleeve channel (402) may be configured to receive at least a portion of the core element (300) extending from the leading edge end (310) of the core element (300). The engagement sleeve (400) may include an engagement member (420) having an outer surface (422) and an inner surface (404). The outer surface (422) of the engagement member (420) may be configured to engage with the contact surface (104) of the first member (100). The inner surface (404) of the engagement member (420) may have a first region (452) and a second region (454). The second region (454) may extend from a free end (440) constituting the leading edge end (410) to the end of the first region (452), and the first region (452) may extend toward the opening (406) of the engagement sleeve channel (402). The inner surface (404) of the engagement member (420) and the outer engagement surface (302) of the core element (300) are configured to slide relative to each other in the first region (452) and the second region (454). The core element (300) and the engagement sleeve (400) can be configured such that, as the engagement sleeve (400) enters the cavity (102) of the first member (100), the connector assembly (10, 12, 14) can be operated in a first configuration in which, when the leading edge end (310) of the core element (300) is located in the first region (452) of the engagement member (420), the engagement sleeve (400) is slidable relative to the contact surface (104) of the cavity (102) of the first member. The connector assembly (10) can be operated in a second configuration in which, when the leading edge end (310) of the core element (300) engages with the second region (454) of the engagement member (420), the engagement sleeve (400) is locked relative to the first member (100).

[0009] The core element (300) and the engagement sleeve (400) may be configured such that when the leading edge end (310) of the core element (300) slides along at least a portion of the second region (454) of the inner surface (404) of the engagement member (420), the outer surface (422) of the engagement member (420) is pushed to engage with the cavity contact surface (104) of the first member (100) until the connector assembly (10) is in the second configuration.

[0010] When the leading edge end (310) of the core element (300) is located in the first region (452) of the inner surface (404) of the engaging member (420), a clearance fit can be maintained between the inner surface (404) of the engaging sleeve (400) and the outer engaging surface (302) of the core element (300).

[0011] When the leading edge end (310) of the core element (300) engages with the second region (454) of the inner surface (404) of the engaging member (420), an interference fit may exist between the inner surface (404) of the engaging sleeve (400) and the outer engaging surface (302) of the core element (300).

[0012] The core element (300) and the engagement sleeve (400) may be configured such that, when the leading edge end (310) of the core element (300) moves from engagement with the second region (454) of the engagement member (420) to being located in the first region (452) of the engagement member (420), the outer engagement surface (302) of the core element (300) disengages from the inner surface (404) of the engagement sleeve (400) to allow the engagement sleeve engagement member (420) to disengage from the cavity contact surface (104) of the first member (100), and the connector assembly (10) transitions from a second configuration to a first configuration to allow the engagement sleeve (400) to slide along the cavity contact surface (104) of the first member (100).

[0013] In the first configuration, the free end (440) of the connecting member (420) is a first distance (d1) from the central axis (450); and in the second configuration, the free end (440) of the connecting member (420) is a second distance (d2) from the central axis (450), the second distance (d2) being greater than the first distance (d1).

[0014] In the first configuration, the diameter of the outer surface (422) of the joining member can increase from a first diameter to a second diameter from the leading edge end (410), and then extend toward the trailing edge end (412) with a region (470) of constant diameter.

[0015] In the first configuration, the diameter of the inner surface (404) of the joining member may increase from the leading edge end (410) along at least a portion of the inner surface (404) of the joining member toward the trailing edge end (412).

[0016] The diameter of the outer mating surface (302) of the core element (300) may increase from the leading edge end (310) toward the trailing edge end (312) and terminate at a region (370) with a constant diameter.

[0017] The core element (300) may be provided with a first locking feature (330). The engaging sleeve (400) may be provided with a second locking feature (430). The first locking feature (330) and the second locking feature (430) are configured to engage with each other to lock the engaging sleeve (400) and the core element (300) together. The first locking feature (330) and the second locking feature (430) are configured to disengage from each other, such that the engaging sleeve (400) and the core element (300) are separable.

[0018] The first locking feature (330) and the second locking feature (430) may be positioned such that, prior to engagement of the first locking feature (330) and the second locking feature (430), the leading edge end (310) of the core element (300) is in the first region (452) of the engagement sleeve (400), and the connector assembly (10, 12, 14) is in the first configuration. After engagement of the first locking feature (330) and the second locking feature (430), the leading edge end (310) of the core element (300) may be in the second region (454) of the engagement sleeve (400).

[0019] The outer surface (422) of the engagement member of the engagement sleeve (400) may be smooth or have at least one engagement tooth (424).

[0020] The core element (300) can substantially close the engagement sleeve channel (402).

[0021] The core element (300) may be provided with an opening (306) at the trailing edge end (312) for receiving the second member (200) and engaging with the second member (200).

[0022] The engagement sleeve (400) may include additional engagement members (420). The plurality of engagement members (420) may be spaced apart from each other about the central axis (450). Each engagement member (420) may have an outer surface (424) for engaging with the contact surface (104) of the cavity (102), an inner surface (404) for engaging with the outer engagement surface (302) of the core element (300), and a free end (440) at the leading edge end (410), such that the free ends (440) are spaced apart from each other about the central axis (450) and by slots (408).

[0023] The first locking feature (330) may be disposed on the outer surface of the core element (300), between the portion where the radially outer engagement surface (302) engages with the radially inner surface (404) of the engagement member (420) and the trailing edge end (312) of the core element (300).

[0024] The second locking feature (430) may be disposed on the inner surface of the engagement sleeve (400), between the radial inner surface (404) of the engagement member (420) and the rear edge end (412) of the engagement sleeve (400).

[0025] The first locking feature (330) on the core element (300) may be a first thread. The second locking feature (430) on the engagement sleeve (400) may be a second thread. When the first locking feature (330) and the second locking feature (430) engage, a transition from the first configuration to the second configuration begins.

[0026] The radial inner surface (404) of the engaging sleeve engaging member (420) may be smooth, and the outer engaging surface (302) of the core element (300) may also be smooth, such that when the leading edge end (310) of the core element (300) is located in the second region (454) of the engaging sleeve (400), the radial inner surface (404) of the engaging member (420) contacts the outer engaging surface (302) of the core element.

[0027] The first locking feature (330) may be disposed on the outer engagement surface (302) of the core element (300) and may include a mounting member (340) extending outward from the outer engagement surface (302) and along the outer engagement surface (302) from the leading edge (310) of the core element (300) toward the trailing edge (312) of the core element (300); and may also include teeth (342) disposed on one side of the mounting member extending in a first circumferential direction.

[0028] The second locking feature (430) may be provided on one side of the engagement member (420) of the engagement sleeve (400) and includes a tooth (442) extending in a second circumferential direction opposite to the first circumferential direction.

[0029] The teeth (342) of the first locking feature (330) and the teeth (442) of the second locking feature (430) are configured to lock into each other, and when the teeth (342) of the first locking feature (330) and the teeth (442) of the second locking feature (430) are engaged, the core element (300) can be locked together with the engagement sleeve (400).

[0030] The core element (300) and the engagement sleeve (400) can rotate relative to each other about the central axis (450) to engage and disengage the first locking feature (330) and the second locking feature (430).

[0031] A component kit for a structure may also be provided, comprising: a connector assembly (10, 12, 14) as described in this disclosure and a first member (100) comprising a cavity (102) having a contact surface (104) and an opening (106) leading to the cavity (102) for receiving at least the leading edge end (410) of the engagement sleeve (400).

[0033] The diameter of the contact surface (104) of the cavity (102) for engaging with the sleeve engagement member (420) may be at most the same as the outer diameter of the outer surface (422) of the sleeve engagement member.

[0034] The component kit may further include a second component (200); the second component (200) extends from and / or is coupled to the core element (300), such that the first component (100) is coupled to the second component (200).

[0035] The first component (100) and / or the second component (200) may be a post or a railing.

[0036] The first component (100) may be a column, and the second component (200) may be an end cap or mounting piece as an accessory.

[0038] In summary, a connector assembly and a set of components for a structure are provided. A single user can easily assemble the connector assembly (10, 12, 14) elements and combine them with structural parts and / or accessories without the need for additional parts (e.g., screws) or the use of any adhesive materials.

Detailed Implementation

[0040] This disclosure relates to a connector assembly 10, 12, 14, including a set of components of the connector assembly 10, 12, 14 of this disclosure, and a method for assembling an assembly including the connector assembly 10, 12, 14 and / or the set of components of this disclosure.

[0041] This disclosure relates to connector assemblies 10, 12, 14 for engagement with a first member 100 (i.e., a structural member), the first member 100 comprising a cavity 102 having a contact surface 104 and an opening 106 leading to the cavity 102, for example, being a hollow conduit or pipe, which may be provided in the form of a post or railing. Connector assemblies 10, 12, 14 are configured to engage in a cavity formed by the conduit wall. Connector assemblies 10, 12, 14 are configured to engage at an open end of the tubular member and / or structural member 100, the open end being formed by an opening leading to a cavity formed by the wall of the tubular member and / or structural member 100.

[0042] As shown in the figure, the cross-section of the structural member 100 and / or cavity 102 may be circular. In other examples, the cross-section of the structural member 100 and / or cavity 102 may be polygonal (e.g., square).

[0043] Connector assemblies 10, 12, and 14 include a core element 300 and a mating sleeve 400. In the example shown, the core element 300 and the mating sleeve 400 have circular cross-sections. In other examples, the core element 300 and the mating sleeve 400 may have polygonal cross-sections (e.g., squares).

[0044] Figures 1 to 7 A first example 10 of a connector assembly as described in this disclosure is shown. Figures 8 to 13 A second example 12 of the connector assembly as described in this disclosure is shown. Figures 14 to 20 A third example 14 of the connector assembly as described in this disclosure is shown. Although the different examples 10, 12, and 14 have different features, they share common features. These common features are indicated by the same reference numerals.

[0045] In all examples of this disclosure, the connector assemblies 10, 12, 14 include a core element 300 having an outer engagement surface 302 (e.g., a radially outer engagement surface 302) extending from a leading edge end 310 (e.g., a leading edge end region 310) toward a trailing edge end 312.

[0046] The connector assemblies 10, 12, and 14 further include a mating sleeve 400 extending from a leading edge 410 to a trailing edge 412. The mating sleeve 400 is formed by a channel 402 having a central axis 450. The mating sleeve channel 402 has an opening 406 at the trailing edge 412. The mating sleeve channel 402 may also have an opening at the leading edge 410.

[0047] The engagement sleeve opening 406 and engagement sleeve channel 402 are configured to receive at least a portion of the core element 300 extending from the leading edge end 310 of the core element 300.

[0048] The engaging sleeve 400 includes an engaging member 420 having an outer surface 422 (e.g., a radially outer surface 422) configured to engage with a cavity contact surface 104 of the first structural member 100. The engaging member 420 also includes an inner surface 404 (e.g., a radially inner surface 404) for engaging with an outer engaging surface 302 of the core element 300. The engaging member 420 extends to a free end 440 at the leading edge end 410. That is, the engaging member 420 terminates at the free end 440 at the leading edge end 410.

[0049] The engaging member 420 may be referred to as a "leg" or "finger" because it extends from the base (e.g., a ring) of the engaging sleeve 400 (which has a trailing edge end 412) to the free end 410. The engaging member 420 may be elastically flexible. The engaging member 420 may be elastically deformable. The engaging member 420 may pivot relative to the base (e.g., a ring) of the engaging sleeve 400. The engaging member 420 may be flexible (e.g., bendable) along its length.

[0050] In some examples, such as Figures 1 to 7 As shown, at least one engagement tooth 424 is provided on the outer surface 422 of the engagement member 420 of the engagement sleeve 400 and is configured to be pressed into the cavity contact surface 104 of the first structural member 100.

[0051] In other examples, such as Figures 8 to 24 As shown, the outer surface 422 of the engagement member 420 of the engagement sleeve 400 is smooth and is configured to press against the cavity contact surface 104 of the first structural member 100, but not to be embedded in the cavity contact surface.

[0052] In some examples, such as Figures 8 to 24As shown, the core element 300 is configured to substantially close (and, in some examples, seal) the engagement sleeve channel 402. In some examples, the core element 300 may be solid. The core element 300 has an opening 318 at its leading edge end 310 and a channel 308 extending partially, but not completely, along a path leading to the trailing edge end 312.

[0053] In other examples, such as Figures 1 to 8 As shown, the core element 300 comprises an opening 306 at a trailing edge 312, an opening 318 at a leading edge 310, and a channel 1308 extending between the trailing edge 312 and the leading edge 310. The channel 1308 is configured to receive and engage with a second member 200, for example, the second member 200 may be a second structural member or fitting 200. For example, the channel 1308 is configured to be embedded in the end of a post or to receive an adapter that is sequentially fixed to another post.

[0054] Or, such as Figure 1 As shown, the core element 300 may have additional engagement features for cooperative engagement with engagement features on the second structural member or fitting 200. Therefore, the second structural member or fitting 200 can be positioned and locked onto the portion of the core element 300 extending from the sleeve 400.

[0055] exist Figures 8 to 13 The connector assembly 12 shown in the second example and Figures 14 to 22 In the connector assembly 14 of the third example shown, a second structural member or accessory 200 can be attached to the trailing edge end 312 of the core element 300. For example, the second structural member or accessory 200 can be glued / bonded to the trailing edge end 312, or engagement features can be provided on the trailing edge end 312 for mounting the second structural member or accessory 200 to the trailing edge end 312. Figure 23 , Figure 24 As shown, the engagement feature can be configured as a second core element 1300, identical to the core element 300 described herein, engaging at their respective trailing edge ends 312, 1312 and extending to their respective leading edge ends 310, 1310. In this example, the second structural member or accessory 200 can be attached and secured to the second core element 1300 in the same manner as the first structural member 100 is attached and secured to the first core element 300.

[0056] The inner surface 404 of the engaging member 420 has a first region 452 extending in a direction away from the opening 406 to a second region 454, and the second region 454 extends from the end of the first region 452 to a free end 440 formed by the leading edge end 410. That is, the second region 454 extends from the free end 440 formed by the leading edge end 410 of the engaging member 420 to where it intersects with the end of the first region 452, and the first region 452 extends at least partially along the path toward the opening 406 of the engaging sleeve channel 402 (i.e. toward the trailing edge end 412).

[0057] The engaging sleeve 400 includes additional engaging members (e.g., fingers / legs) 420, which may have the same or similar configuration as described above. A plurality of engaging members 420 may be spaced apart from each other about a central axis 450 via slots 408. Each engaging member 420 has an outer surface 424 (e.g., a radially outer surface) for engaging with a contact surface 104 of the cavity 102, an inner surface 404 (e.g., a radially inner surface) for engaging with an outer engaging surface 302 of the core element 300, and a free end 440 at a leading edge end 410. The free ends 440 may be spaced apart from each other about the central axis 450 via slots 408 located between the free ends 440. The engaging members 420 may be freely movable relative to each other. A gap may be maintained between the free ends 440.

[0058] The inner surface 404 of the engaging sleeve 400 and the outer engaging surface 302 of the core element 300 are configured to allow the core element 300 to move (i.e., translate) relative to a first region 452 and a second region 454 of the inner surface 404 of the engaging sleeve 400. In other words, the outer engaging surface 302 of the core element 300 is configured to move (i.e. translate) along the first region 452 and the second region 454 of the inner surface 404 of the engaging sleeve 400.

[0059] The inner surface 404 of each engagement member 420 on the engagement sleeve may be smooth. The outer engagement surface 302 of the core element 300 may be smooth. The outer engagement surface 302 of the core element 300 is configured to slide along a first region 452 and a second region 454 of the inner surface 404 of the engagement sleeve 400. Therefore, since the inner surface 404 of each engagement member 420 and the outer engagement surface 302 of the core element 300 are smooth, the outer engagement surface 302 of the core element 300 can enter into and exit from the engagement sleeve channel 402 and translate relative to the inner surface of the engagement sleeve 400 without causing material of one component to embed (e.g., cut into) the material of another component, the inner surface of the engagement sleeve 400 including the inner surface 404 of each engagement member 420.

[0060] The features of the core element 300 and the engagement sleeve 400 can be sized relative to each other such that when the leading edge end 310 of the core element 300 is located in a first region 452 of the inner surface 404 of the engagement member 420 (e.g., adjacent to), a clearance fit can be maintained between the inner surface 404 of the engagement member 420 and the outer engagement surface 302 of the core element 300.

[0061] Therefore, when the leading edge 310 of the core element 300 is in the second region 454 of the engagement sleeve 400, the entire radial inner surface 404 of each engagement member 402 of the engagement sleeve 400 can contact the cooperative region of the outer engagement surface 302 of the core element.

[0062] The features of the core element 300 and the engagement sleeve 400 can be sized relative to each other such that when the leading edge end 310 of the core element 300 engages with the second region 454 of the inner surface 404 of the engagement member 420, there is an interference fit between the inner surface 404 of the engagement member 420 and the outer engagement surface 302 of the core element 300.

[0063] The core element 300 and the engagement sleeve 400 are configured such that, as the engagement sleeve 400 enters the cavity 102 of the first structural member, the connector assemblies 10, 12, and 14 are in a first configuration in which the engagement sleeve 400 is slidable relative to the contact surface 104 of the cavity 102 of the first structural member, and the leading edge 310 of the core element 300 is located (e.g., adjacent) in a first region 452 of the engagement member 420. The core element 300 and the engagement sleeve 400 can also be configured such that, when the connector assemblies 10, 12, and 14 are in a second configuration, the engagement sleeve 400 is locked relative to the first structural member 100, and the leading edge 310 of the core element 300 engages with a second region 454 of the engagement member 420. That is, the engagement sleeve 400 is freely movable (e.g., slidable) relative to the contact surface 104 of the cavity 102 of the first structural member until the leading edge 310 of the outer engagement surface 302 of the core element 300 engages with the second region 454 of the engagement member 420.

[0064] The core element 300 and the engagement sleeve 400 are configured such that when the leading edge end 310 of the core element 300 moves (e.g., slides) at least a portion of the second region 454 of the inner surface 404 of the engagement member 420 from the first region 452, the outer surface 422 of the engagement member 420 is pushed to engage with the cavity contact surface 104 of the first structural member 100 until the connector assemblies 10, 12, 14 are in the second configuration.

[0065] The core element 300 and the engagement sleeve 400 can be configured such that, when the core element 300 moves along the engagement sleeve channel 402 in a first direction (e.g., parallel to the central axis 450), the outer engagement surface 302 of the core element 300 engages with the inner surface 404 of the engagement member 420, and the connector assemblies 10, 12, 14 transition from a first configuration to a second configuration. The first direction refers to the direction from the trailing edge 412 to the leading edge 410 of the engagement sleeve 400.

[0066] The core element 300 and the engagement sleeve 400 may be further configured such that, when the core element 300 moves along the engagement sleeve channel 402 in a second direction (e.g., parallel to the central axis 450), the outer engagement surface 302 of the core element 300 disengages from the inner surface 404 of the engagement sleeve 400, and the connector assemblies 10, 12, 14 transition from a second configuration to a first configuration, allowing the engagement sleeve 400 to slide along the cavity contact surface 104 of the first structural member 100. The second direction refers to the direction from the leading edge end 410 to the trailing edge end 412 of the engagement sleeve 400.

[0067] In other words, the core element 300 and the engagement sleeve 400 are configured such that when the leading edge end 310 of the core element 300 enters (i.e., begins to move) into the second region 454 of the engagement member 420 in a first direction, the outer engagement surface 302 of the core element 300 is pushed to engage with the inner surface 404 of the engagement member 420, and the outer surface 422 of the engagement sleeve engagement member 420 is pushed to engage with the cavity contact surface 104 of the first structural member 100.

[0068] The core element 300 and the engagement sleeve 400 are configured such that when the leading edge end 310 of the core element 300 moves in a first region 452 of the inner surface 452 (e.g., adjacent) to engage with a second region 454 of the inner surface 404 of the engagement member 420, such that the outer engagement surface 302 of the core element 300 is pushed to engage with the inner surface 404 of the engagement member 420, and the outer surface 422 of the engagement member 420 is pushed to engage with the cavity contact surface 104 of the first structural member 100, until the connector assemblies 10, 12, 14 are in the second configuration.

[0069] The core element 300 and the engagement sleeve 400 are configured such that when the leading edge region 310 of the core element 300 moves from engaging with the second region 454 of the engagement member 420 to being located in the first region 452 of the engagement member 420 (i.e., moving in the second direction), the outer engagement surface 302 of the core element 300 disengages from the inner surface 404 of the engagement sleeve 400, allowing the engagement sleeve engagement member 420 to disengage from the cavity contact surface 104 of the first structural member 100, and causing the connector assemblies 10, 12, 14 to switch from the second configuration to the first configuration, so as to allow the engagement sleeve 400 to slide along the cavity contact surface 104 of the first structural member 100.

[0070] The diameter of the outer mating surface 302 of the core element 300 increases from the leading edge 310 toward the trailing edge 312, terminating at a constant diameter region 370. That is, the outer mating surface 302 of the core element 300 has a truncated conical region 360 extending from the leading edge 310 toward the constant diameter region 370 toward the trailing edge 312. The movement of the core element 300 along the inner side of the mating sleeve 400, particularly along the inner side of the mating member 420, forces the mating member 420 away from the central axis 450.

[0071] like Figure 4 , Figure 9 , Figure 10 , Figure 11 , Figure 16 , Figure 17 As shown, when connector assemblies 10, 12, and 14 are in the first configuration, the outer surface 422 of the mating member has a truncated conical region 460, the diameter of which increases from a first diameter to a second diameter from the leading edge end 410. A constant diameter region 470 extends from the second diameter end of the truncated conical region 460 toward the trailing edge end 412. Therefore, the surface constituting the constant diameter region 470 extends substantially parallel to the central axis 450. The value of the first diameter can be in the range of 0.90 to 0.98 of the value of the second diameter.

[0072] like Figure 4 , Figure 10 , Figure 11 , Figure 16 , Figure 17 As shown, in the first configuration of connector assembly 10, the free end 440 of engagement member 420 is at a first distance d1 from the central axis 450. In the first configurations of connector assemblies 10, 12, and 14, the distance between the outer surface 422 of engagement member and the central axis 450 varies with the length of the outer surface 422 of engagement member.

[0073] like Figure 5 , Figure 13 , Figure 19 As shown, in the second configuration of connector assemblies 10, 12, and 14, the core element 300 forces at least a portion of the engagement member 420 away from the central axis 450, such that the free end 440 of the engagement member is at a second distance d2 from the central axis 450. The second distance d2 is greater than the first distance d1. That is, in the second configuration of connector assemblies 10, 12, and 14, the free end 440 of the engagement member 420 is at a second distance d2 from the central axis 450, and the second distance d2 is greater than the first distance d1. The second distance d2 can be at least equal to the inner radius of the cavity 102 of the first structural member 100.

[0074] In the second configuration of connector assemblies 10, 12, and 14, the distance between the outer surface 422 of the engagement member and the central axis 450 can be substantially constant because, in the second configuration, the outer surface 422 of the engagement member is pressed against the contact surface 104 of the first structural member 100. In the second configuration of connector assemblies 10, 12, and 14, the distance between the outer surface 422 of the engagement member and the central axis 450 can be maximized at the free end 440 and gradually decreases along at least a portion of the outer surface 422 of the engagement member.

[0075] In such Figure 9 In the first configuration shown (and applicable to other examples), the diameter of the inner surface 404 of the joining member may increase from id1 to id2 from the leading edge end 410 along at least a portion of the inner surface 404 of the joining member toward a constant diameter id3 region, and the constant diameter region extends from the diameter of id2 to the trailing edge 412.

[0076] Therefore, when at least a portion of the core element 300 enters and moves along the channel 402 of the sleeve member 400, and when the outer engagement surface 302 of the core element 300 presses against at least a portion of the inner surface 404 of the engagement member, an interaction occurs between the truncated conical shape of the outer engagement surface 302 of the core element 300 and / or the inner surface 404 of the engagement member, causing the core element 300 to be further pushed into the channel 402 and towards the free end 440 of the engagement member 400, thereby pushing the free end 440 of the engagement member 400 and at least a portion of the outer surface 422 of the engagement member away from the central axis 450. In this way, in practice, when the core element 300 is pushed along the channel 402, at least a portion of the outer surface 422 of the engagement member engages with the contact surface 104 of the first structural member 100.

[0077] In various examples of connector assemblies 10, 12, 14 described in this disclosure, the core element 300 may be provided with a first locking feature 330 and / or the engagement sleeve 400 may be provided with a second locking feature 430. The first locking feature 330 and the second locking feature 430 may be configured to engage with each other to lock the engagement sleeve 400 and the core element 300 together, and may be configured to disengage from each other such that the engagement sleeve 400 and the core element 300 are separable (i.e., can move relative to each other, for example, slide, so that the assembly can be disassembled).

[0078] The first locking feature 330 and the second locking feature 430 are respectively disposed on the core element 300 and the engagement sleeve 400, such that when the leading edge 310 of the core element 300 is pushed along the first region 452 of the channel 402 of the sleeve 400 in the direction from the trailing edge end 412 to the leading edge end 410, and before the first locking feature 330 engages with the second locking feature 430, the connector assemblies 10, 12, 14 are in a first configuration.

[0079] The first locking feature 330 and the second locking feature 430 are respectively disposed on the core element 300 and the engagement sleeve 400, such that when the leading edge end 310 of the core element 300 engages with the second region 454 of the engagement sleeve 400 and / or after the leading edge end 310 of the core element 300 engages with the second region 454 of the engagement sleeve 400, the first locking feature 330 engages with the second locking feature 430.

[0080] When the first locking feature 330 and the second locking feature 430 engage, the connector assemblies 10, 12, and 14 begin to transition from the first configuration to the second configuration. The second configuration is achieved by locking the first locking feature 330 with the second locking feature 430.

[0081] Regarding the connector assembly 10 in the first example Figures 1 to 7 Neutralization regarding the connector assembly 12 of the second example Figures 8 to 13 In the example shown, a first locking feature 330 is disposed on the outer surface of the core element 300 (e.g., the radial outer surface), between the region where the radial outer engagement surface 302 engages with the radial inner surface 404 of the engagement member 420 and the trailing edge end 312 of the core element 300. A second locking feature 430 is disposed on the inner surface of the engagement sleeve 400 (e.g., the radial inner surface), between the radial inner surface 404 of the engagement member 420 and the trailing edge end 412 of the engagement sleeve 400.

[0082] The first locking feature 330 on the core element 300 may be configured as a first thread. The second locking feature 430 on the engaging sleeve 400 may be configured as a second thread. The first thread and the second thread engage with each other. The core element 300 and the engaging sleeve 400 may rotate relative to each other about a central axis 450 to engage and disengage the first locking feature 330 and the second locking feature 430. With the locking features 330 and 430 engaged, the action of rotating the core element 300 and the engaging sleeve 400 relative to each other about the central axis 450 allows the core element 300 to move along the sleeve channel 402. The thread may be a four-start thread.

[0083] When the first locking feature 330 and the second locking feature 430 are engaged, the core element 300 and the sleeve member 400 are prevented from sliding relative to each other along the central axis 450.

[0084] Regarding the third example connector assembly 14 Figures 14 to 22 In the example shown, and as Figures 20 to 22 As best shown in the diagram, a first locking feature 330 is disposed on the outer engagement surface 302 (e.g., radially outer surface) of the core element 300, including a mounting member 340 (e.g., an extension or base) extending outward (e.g., radially outward) from the outer engagement surface 302 and extending a portion along the outer engagement surface 302 in a direction from the leading edge end 310 of the core element 300 toward the trailing edge end 312 of the core element 300. A plurality of mounting members 340 are configured to be spaced apart from each other around the outer engagement surface 302 of the leading edge end 310 of the core element 300.

[0085] exist Figures 14 to 22 In the example shown, a plurality of engaging members 420 spaced apart from each other around the boundary / circumference of the sleeve 400 are provided, and the dimensions of the mounting members or each mounting member 340 are configured to fit into a slot 408 defined between two adjacent engaging members 420. The outer diameter defined by the outer surface (e.g., radial outer surface) of the mounting member 340 is no greater than the diameter of the channel 402, such that the mounting member 340 can pass through the channel 402 and then into the slot 408 between the engaging members 420.

[0086] Mounting member 340 has a side surface 344, and teeth 342 extend from the side surface 344 in a first direction (e.g., a first circumferential direction). A second locking feature 430 is provided on the side surface 444 of the engaging sleeve 400 engaging member 420 and includes teeth 442 extending in a second direction (e.g., a second circumferential direction) opposite to the first circumferential direction.

[0087] like Figures 20 to 22As shown in the best illustration, the first and second directions are perpendicular to the direction defined by the central axis 450 between the leading edge end 410 and the trailing edge end 412. That is, in the example where the cross-section of the core element 300 and the sleeve member 400 is circular, the first direction extends about the central axis 450 in a first manner (e.g., clockwise or counterclockwise), and the second direction extends about the central axis 450 in a second manner (e.g., counterclockwise or clockwise) in the opposite direction to the first direction.

[0088] The teeth 342 of the first locking feature 330 and the teeth 442 of the second locking feature 430 can be configured to engage with each other, such that when the teeth 342 of the first locking feature 330 and the teeth 442 of the second locking feature 430 are engaged, the core element 300 and the engagement sleeve 400 are locked together.

[0089] like Figures 20 to 22 As shown in the best illustration, teeth 342, 442 can be essentially serrated, such that the dimensions of the tooth grooves of the serrations 342 of the first locking feature 330 are designed to receive and position the teeth 442 of the second locking feature 430, and such that the dimensions of the tooth grooves of the serrations 442 of the second locking feature 430 are designed to receive and position the teeth 342 of the first locking feature 330.

[0090] like Figure 21 As shown, the serrations 342 and 442 can be positioned such that when the leading edge 310 of the core element 300 translates toward and (optionally) beyond the leading edge 410 of the engaging member 420 (i.e., in the first direction), the serration 342 can slide over / beyond the serration 442 (i.e., slide into and out of the tooth groove of another set of teeth). However, the serrations 342 and 442 can also be positioned such that when the teeth 342 and 442 are engaged, if the leading edge 310 of the core element 300 is pushed toward the trailing edge 412 of the engaging member 420 (i.e., in the second direction), the teeth 342 and 442 lock together (i.e., because one set of teeth 342 and 442 is located in the tooth groove of the other set of teeth 342 and 442) to prevent relative movement between the core element 300 and the sleeve member 400.

[0091] like Figure 22 As shown, the engagement between the core element 300 and the engagement sleeve 400 is released by rotating the core element 300 and the engagement sleeve 400 relative to each other (or by rotating one of the core element 300 and the engagement sleeve 400 relative to the other), such that the teeth 342 of the mounting member 340 can be lifted away from the teeth 442 of the engagement member 420. For example, as Figure 22 As shown, if the core element 300 rotates about the central axis 450 in direction A, the mounting member 340 moves away from the teeth 442 on the engagement member.

[0092] As shown, the engaging sleeve 400 may include a plurality of engaging members (e.g., legs) 420 having the same configuration. Mounting members 340 may be disposed only in some of the slots 408 between the engaging members 420. Therefore, mounting members 340 may be disposed in every other slot 408 between the engaging members 420, such that the engaging members 420 bend into the free space defined by the slots 408 due to deflection of the mounting members 340. That is, some of the engaging members 420 are configured to bend elastically in the circumferential direction in response to a force applied to the mounting members 340.

[0093] Some of the engagement members 420 may be narrower than others. For example, an engagement member 420 having teeth 442 thereon may be wider than an engagement member 420 configured to deflect when the mounting member 340 is pressed into it.

[0094] Therefore, the core element 300 and the engagement sleeve 400 can rotate relative to each other about the central axis 450 to disengage the first locking feature 330 and the second locking feature 430.

[0095] As described above, the connector assemblies 10, 12, and 14 of this disclosure can be configured to form a kit with other components. For example, as shown in the accompanying drawings associated with each example, the kit may include a first member 100 (e.g., a first structural member) comprising a cavity 102 having a contact surface 104 and an opening 106 leading to the cavity 102 that receives at least the leading edge end 410 of the engagement sleeve 400. The contact surface 104 of the cavity 102 for engagement with the sleeve engagement member 420 has a substantially constant cross-sectional area and / or a constant diameter.

[0096] The assembly may also include a second component 200 (e.g., a structural component and / or an accessory). Thus, during assembly, the second component 200 may extend from and / or be coupled to the core element 300, such that the first component 100 is coupled to the second component 200 via connector assemblies 10, 12, 14.

[0097] The first component 100 and / or the second component 200 may be configured as hollow pipes and / or conduits. The first component 100 and / or the second component 200 may be configured as hollow columns or hollow railings.

[0098] The first component 100 and / or the second component 200 are formed by a cavity 102 having a contact surface 104 and an opening 106 leading to the cavity 102. In an example where the first component 100 and the second component 200 are hollow pipes / ducts, the opening 106 may be located at the end of the pipe / duct. In an example where the first component 100 and the second component 200 are hollow pipes / ducts, the hollow pipe / duct has a substantially constant diameter along its length and / or at least toward its open end, and the wall has a constant thickness along its length and / or toward its open end, and the cavity 102 may be formed by the inner surface of the wall of the pipe / duct.

[0099] Therefore, for example, if it is circular, the diameter (e.g., width) of the cavity contact surface 104 for engaging with the sleeve engagement member 420 can be at most the same as the outer diameter of the outer surface 422 of the sleeve engagement member.

[0100] The connector assemblies and / or kits described in this disclosure may constitute at least a portion of the following components: a. A fence component; b. A machine protection component; c. A handrail assembly; d. A railing assembly; e. A decorative component; f. A climbing frame component; g. A sports field component; h. A temporary support structure component; I. A scaffolding assembly; j. A barrier component; k. A column assembly; or l. A support structure for a temporary shelter system, such as a pagoda, pavilion, or tent.

[0101] Figure 25 Exemplary structures constructed using the kit components described in this disclosure are shown. Any example of the connector assemblies 10, 12, 14 described in this disclosure can be combined with T-joints 500, cross joints 600, and / or L-joints 700 to assemble with structural members 100, 200 into a structure. For example, connector assemblies 10, 12, 14 can connect a first structural member (e.g., a pipe) 100 to a T-joint, the T-joint to another connector assembly of another structural member 100, 200, and / or the T-joint directly to another structural member 100, 200.

[0102] The second component 200 may be an end cap or mounting for an accessory. The engagement sleeve 400 may provide fluid communication between the cavity 102 of the first component 100 and the outer surface of the cap or mounting (e.g., to provide a vent from the interior of the structure to the space surrounding the component when assembled).

[0103] An elastic washer or seal 800 is provided between the core element 300 and the rear edge 412 of the engaging sleeve 400. It can be configured as an elastic member to ensure that the core element 300 can be tightened downward onto the engaging sleeve 400 and to ensure that there is a force on the locking feature between the core element 300 and the engaging sleeve 400 to keep the locking feature engaged.

[0104] In operation, the engaging sleeve 400 may first enter the cavity 102 (e.g., the end of a pipe or conduit constituting structural members 100, 200). The engaging member 420 slides into the cavity 102 along the contact surface 104. Then, the core element 300 enters the opening 406 of the sleeve 400 and passes through the channel 402. As described above, when the core element 300 travels along the channel 402 and engages with the engaging member 420, the inner surface 404 of the engaging member 420 deflects outward, and the outer surface 422 of the engaging member engages with the contact surface 104 of the structural member 100 to secure them together.

[0105] The core element 300 can be locked to the engagement sleeve 400 by locking devices 330, 430, thereby preventing the core element 300 from sliding out of the engagement sleeve 400 and ensuring that the core element 300 and the engagement sleeve 400 remain locked.

[0106] When needed, the core element 300 can be unlocked from the engaging sleeve 400 and removed from the sleeve 400 by an inverted assembly process. With the core element 300 removed, the engaging member 420 is free to deflect inward, thus removing the engagement between the engaging member 420 and the structural contact surface 104.

[0107] Therefore, a connector assembly and a kit for a structure are provided, which offer significant advantages over examples of the prior art.

[0108] The connector assembly comprises only two parts that can be assembled onto a structural member in series (i.e., one at a time). This means that a single user can easily perform the connection, thus allowing fewer people to construct the structure using the connector assembly described in this disclosure.

[0109] Because only two components are required—the engaging sleeve 400 and the core element 300—fewer manufacturing processes and materials are needed to produce the assembly, simplifying manufacturing and transportation. The connection between the core element 300 and the engaging sleeve 400 also allows the sleeve to be connected to structural components, thus requiring fewer steps for the user to complete the assembly. Having only two usable parts also means that users are less likely to make mistakes during the assembly process.

[0110] Because no fastening components (such as screws and bolts) are required, the likelihood of component damage (such as misthreading) during the construction process is relatively low.
