    DETAILED DESCRIPTION [00030] A preferred embodiment of an articulated coupling 10 secured around two preferably grooved tube segments 2, 4 is shown in figure 1 so as to couple the tube segments 2, 4 together along the tube axis XX . The preferred coupling includes two housing components 12, 14 that surround a (hidden) gasket to form a fluid tight seal around the end of the pipe segments 2, 4. More specifically, the preferred coupling 10 includes an upper housing 12 and a lower housing 14, each of which is preferably sized to fit and house approximately half of the pipe assembly. Alternatively, coupling 10 includes more than two housing components with the proviso that adjacent components can be coupled together in an articulated arrangement as described herein.
    [00031] Coupling 10 includes a coupled end 16 and a diametrically opposite safety end 18. Coupling 10 is preferably pre-assembled for the user so that coupled end 16, the upper housing 12 is coupled to the lower housing 14 by manufacturers before release to the end user. The housing components 12, 14 additionally pivot with respect to each other around the pivot axis P - P located at the coupled end 16. Consequently, a user can place the coupling 10 in an open configuration,
    Petition 870190101124, of 10/09/2019, p. 9/36
    7/21 as seen, for example, in figure 2, locate the lower housing component 15 around the ends of the pipe segments 2, 4 and pivot the upper housing 12 with respect to the lower housing component 14 in order to close the ends of the pipe segment between them in the closed configuration of figure 1. At the safety end 18, the housing components 12, 14 are secured together so that the housing components 12, 14 cannot pivot with respect to each other and one airtight fluid seal is formed around the pipe end segments 2, 4.
    [00032] Coupling 10 is shown in figure 2 in a partially cross-sectional view. In this embodiment, each of the lower and upper housing components 12, 14 is similarly configured. More specifically, the upper housing component 12 includes a first end 16a, a second end 18a with an arcuate segment preferably substantially 12a extending between the first and second ends 16a, 18a. Similarly, the lower housing component 14 includes a first end 16b, a second end 18b, with a preferably arched segment 14a extending between the first and second ends 16a, 18a.
    With the housing components in their closed configuration, the arcuate segments are opposed to define a central DC axis of the coupling 10. Each of the arcuate segments 12a, 14a has an inner surface 12b, 4b defining a gasket cavity for engaging and housing a gasket seal. Each of the arcuate segments 12a, 14a defines the outer peripheral surface segment 12c, 4c of the arcuate segments. Preferably, the peripheral surfaces 12c, 14c of the housing components together define an arcuate to substantially circular profile, but other profiles
    Petition 870190101124, of 10/09/2019, p. 10/36
    Geometric 8/21 are possible as well as polygonal with multiple linear lines.
    [00033] Each of the first end 16a, 16b and the second end 18a, 18b of the first and second housing components 12, 14 is preferably defined by a nut-cushioning extension having a recess and more preferably a through hole 20 for receiving one end of a fastener for coupling the housing components together to each of the coupling end 16 and safety end 18. A preferred pivot fastener 22, shown or engaged within the through holes, is shown in figure 2 20 of the first end nut bolt cushions 16a, 16b of the upper and lower housing components 12, 14. In addition to coupling the housing components 12, 14 together, the pivot clamp 22 provides a relative pivoting movement between the components of upper and lower housing 12, 14 around a pivot axis P, which preferably runs parallel to the central axis C of the coupling then 10. Because the housing components 12, 14 in this embodiment are identical and preferably symmetrical, the preferred pivot fasteners 22 can be installed at either of the two ends 16, 18 of the coupling 10 so that either end of the coupling can serve as the coupling end 16 and the opposite end can serve as the safety end 18. Preferably disposed within the through holes 20 of the central ends 18 a, 18b of the housing components 12, 14 there may be another fastener, preferably a bolt with nut fixed straight secured by a nut (not shown) in order to keep coupling 10 in the closed configuration.
    [00034] A pivot fastener 22 'is shown in figures 3A and 3B.

    The pivot fastener 22 'preferably includes a first element 22'a and a second element 22'b coupled or engaged with the first element 22'a so that elements 22'a, 22'b can pivot with respect to the other to define two or more configurations. For example, the first and second elements 22'a, 22'b are shown in figure 3A in a first configuration in which elements 22'a, 22'b are substantially axially aligned along the YY axis and shown in figure 3b. elements 22'a, 22'b are pivoted with respect to each other so that the first element 22'a extending along the YA-YA axis is inclined with respect to the second element 22'b extending along the YB-YB axis.
    [00035] The first and second elements 22'a, 22'b are preferably substantially identical. A preferred element 22'a is shown in figure 3C. Each of the fastener elements 22'a, 22'b has a preferably enlarged head portion 24a and a stem portion 26a depending on the head portion 24a along the longitudinal axis YA-YA of the element 22'a. The head portions 24a, 24b preferably engage or cooperatively with others to define the pivot relationship between the first and second elements 22'a, 22'b. In a particular preferred embodiment, the head portion 24a includes a first planar bearing surface 24aa located on a plane that includes the central longitudinal axis of the element 22'a. The head portion 24a preferably also includes a second planar shoulder surface 24ab that extends perpendicular to the first planar bearing surface 24aa. In the transition from the enlarged head portion 24 to the preferably narrower stem portion 26a of the elements 22'b is a preferred frustroconic transition portion 24ac. The transition portion 24ac can define a geometry
    Petition 870190101124, of 10/09/2019, p. 12/36
    10/21 alternative such as, for example, circular cylindrical or a stepwise transition from the head portion 24a to the stem portion. The stem portion 26a is preferably threaded to hold the fastener 22 'within the nut-cushioning ends 16, 18 of the coupling housing components 12,
    14.
    [00036] An exploded assembly view of the preferred pivot clamp 22 'is shown in figure 3D. In the assembly, the planar bearing surfaces 24aa, 24ba of the elements 22'a, 22'b engage with each other to define at least one contact line in the plane that includes the central longitudinal axis of the pivot shaft fastener. To hold the two elements together, the preferred fastener 22 'includes a pin element 28 that is arranged within through holes 24ad, 24bd formed in each of the head portions 24a, 24b of the elements 22'a, 22'b for define a P'-P 'pin axis. The through holes 24'ad, 24'bd preferably extend orthogonally through the first planar bearing surfaces 24aa, 24ba in each element 22'a, 22'b. The elements 22'a, 22'b rotate or pivot with respect to each other around pin 28 and its axis P'-P '. Referring again to Figure 3A, the preferred assembled pivot clamp 22 'includes two preferably threaded ends 26a, 26b which are opposed about an enlarged central portion 24a, 24b along the longitudinal axis YY in the axially aligned configuration of the pivot clamp 22 '. The central portion 24a, 24b preferably defines a substantially cylindrical circular outer surface geometry. Alternatively, the central portion 24a, 24b may be cylindrical, rectangular or cubic. The pin 28 preferably defines an axial length that is greater than the width of the central portion 24a, 24b so that the ends of the pin 28 protrude beyond the through-hole openings 24ad,
    Petition 870190101124, of 10/09/2019, p. 13/36
    11/21
    24bd of the respective head portions 24a, 24b of the elements 22'a, 22'b. Alternatively, the pin 28 can be integrally formed in one element 22'a to be received in a through hole or recess formed over the other element 22'b. Alternatively, each of the elements 22'a, 22'b can be formed as well as to have corresponding structures that engage and cooperate with each other so that the elements 22'a, 22'b can pivot with respect to each other another in a manner as described in this document.
    [00037] As described above, fastener 22 is preferably secured within the through holes 20 of the nut-bolt cushions formed at one end 16, 18 of the housing components 12, 14 to provide the coupling 10 with a housing in which the components 12, 14 are coupled together at one end and still pivot with respect to each other around the PP axis. In figure 4A is another view of the assembly of coupling 10 in an open configuration with the preferred pivot clamp 22 'secured at the coupling end 16. Each end of the preferred pivot clamp 22' is secured within the through hole 20 of the extensions damping bolt with nut 16a, 16b of the respective upper and lower housing components 12, 14. To hold the fastener 22 ', a nut 29 is arranged around the threaded rod 26a, 26b of each element 22'a, 22' b of fastener 22 '. With the fastener 22 'installed, the central portion 24 of the fastener is located between the housing components 12, 14 so that the pivot pin 28 and its P'-P' axis is disposed parallel to the central axis CC of the coupling 10 for thereby defining the PP pivot axis for mounting the coupling.
    [00038] With fastener 22 'located properly and
    Petition 870190101124, of 10/09/2019, p. 14/36
    12/21 disposed within the through holes 20 of the bolt damping extensions 1 to 16b, the housing components can pivot with respect to each other around the pivot axis PP to go from the open configuration, as shown , for example, in figure 5A for the closed configuration shown in figure 5B. In the closed configuration of the coupling 10, the fastener 22 'is preferably arranged so that the through holes 20 are substantially axially aligned, and in the open configuration, the fastener 22' is arranged so that the through holes are angled with respect to one another. to the other. The range of angles through which the housing component can pivot with respect to each other is preferably only limited by the angular range over which the two elements 22'a, 22'b can pivot with respect to each other and the interference between the housing components on that angular band. Returning to Figure 3B, the first element 22'a has a preferred angular range of rotation around the 180 and most preferably 210 degrees around the axis of the pivot catch P'-P 'with respect to the second element 22'b. Consequently, the upper component 12 is preferably pivoted through a corresponding range of angular rotation about the pivot axis PP with respect to the housing component 14.
    [00039] To minimize interference between the housing components and to maximize the relative range of motion, the ends of the bolt damping extensions that house the pivot clamp 22 'have an angled notch on the outer edge of the damping extension bolt nut 16a, 16b in the area defining the through hole 20. For example, with reference to figures 4A and 5A, the nut bolt tapers narrowly taper at the outer perimeter edge of the housing ends 16a, 16b to define the angular surface
    Petition 870190101124, of 10/09/2019, p. 15/36
    13/21
    30a, 30b. The angled surfaces provide a preferred notch or gap around the pivot axis P-P through which the housing components 12, 14 can rotate with respect to each other without interference.
    [00040] In order to facilitate the relative movement between the housing components 12, 14 and the closed sealed configuration of the coupling 10 around the pipe segments, it is desirable for the relative pivot movement between the housing components 12, 14 to occur in a common plan. Consequently, the preferred coupling assembly 10 provides that relative rotation between components around the axis YA-YA, YB-YB extending through a through hole 20 is minimized or more preferably eliminated. In the preferred coupling 10, the pivot clamp 22 'engages the lower surface of the bolt-damping extension end with nut 16a, 16b so that the components cannot rotate with respect to each other about the axis YA-YA, YB -YB extending through the through hole 20 of the bolt damping extension with nut 16a, 16b housing the fastener 22 '. In the assembled coupling of figure 4A and as seen in figure 5B, the exposed ends of pin 28 are located within recesses 32 a, 32b formed on the inner surface of the bolt damping extensions 16a, 16b that define the through holes 20 Any tendency for the housing components 12, 14 to rotate with respect to each other is minimized or eliminated by the interaction of the exposed ends of the pin 28 and the inner surface defining the recess 32 that holds the exposed ends of the pin 28.
    [00041] Figures 6A and 6B show planar and cross-sectional views of a bolt damping extension with nut. In this illustrative example, the damping extensions
    Petition 870190101124, of 10/09/2019, p. 16/36
    14/21 nut bolt 16b for the lower housing component 14 are being shown, but the end of the nut bolt damping extensions 18b can be similarly configured as the nut bolt damping extensions 16a, 18a of the component of upper housing 12. In the plan view of figure 6A, the through hole 20 is shown, and close to the through hole opening 20 are the symmetrically opposed recesses 32b around the opening for engaging the exposed ends of pin 28 in the fastener. pivot 22 'preferred. In figure 6B, a cross-sectional view is shown, the recess 32b defines a partially semicircular geometry, although other geometries for the recess 32b can be chosen with the proviso that the recesses are located properly to at least partially house and engage the ends exposed from pin 28. With respect to the geometry of the through hole 20, the cross-sectional area of the through hole 20 preferably varies along its BB elongation axis or may alternatively be constant with the proviso that the opening can accommodate the desired fastener to couple the housing components 12, 14 and / or provide their relative pivot movement around the PP pivot axis. For example, as shown in figure 6C, is another preferred housing component 14 which includes, in flaps the ends 16b, 18b through holes 20 'that define an oval geometry for engaging a correspondingly shaped portion of a fastener to prevent the fastener from turn inside the through hole 20. Thus, a nut can be threaded around the fastener in the oval shape with only one hand.
    [00042] Due to the preferred symmetrical configuration of the housing components, as indicated above, the preferred pivot clamp 22 can be installed at any end 16, 18 of the coupling
    Petition 870190101124, of 10/09/2019, p. 17/36
    15/21
    10. Furthermore, due to the common preferred configuration of the housing components, a single housing component can serve either as the upper housing component or as the lower housing component. Having a single symmetrical housing component design may be desirable in order to eliminate the need to manufacture or inventory additional housing components for the coupling assembly. In addition, the single housing component design can eliminate assembly errors by avoiding incompatible and improper assembly and dissimilar parts that require specific guidance. The housing components 12, 14 can include features to facilitate their assembly, for example, as shown in figure 6B, the lower housing component 14 can include a tongue 34b and recess 36b at each end to fit respectively with a corresponding recess and tongue in the upper housing. The tongue and recesses are preferably located radially within the damping bolt through holes 20 with nut with respect to the center C of the coupling 10. The details of the tongue and the recess are shown and described in U.S. Patent No. 6,139,069 to is incorporated into this document in its entirety.
    [00043] The preferred use of the pivot clamp can simplify the manufacture of the coupling 10. Because the preferred pivot clamp 22 'provides the pivot action of the coupling, so the precision adjustment and tolerances are in the pivot clamp, there is no no need to machine component housings 12, 14 to form an articulated connection. Consequently, coupling 10 may employ a fusion fit between fastener 22 'and housing components 12, 14. As such, substantial axial alignment or substantial perpendicular orientation between the
    Petition 870190101124, of 10/09/2019, p. 18/36
    16/21 components and coupling elements 10 only require that the components are sufficiently aligned or oriented perpendicular to each other to provide the desired coupling configurations.
    [00044] Preferably, the coupling 10 is pre-assembled with the pivot fastener 22 installed and the upper and lower housing components 12, 14 coupled together. Figures 7A-7B show a preferred method of joining the pipe or pipe segments together using the preferred coupling 10. A gasket seal 40 is arranged over the ends of the pipe segments 2, 4, as shown in the end view of figure 7A (shown illustratively in cross section in figures 9A and 9B). With the fastener 22 preferably in the angled configuration so that the coupling 10 is in the fully open configuration, the lower housing component is brought into engagement with the gasket 40 so as to be received within the housing recess defined by the inner surface 14c of the component bottom housing 14. The housing component 12 is pivoted about the pivot axis PP, with respect to the lower housing component 14 so as to bring the coupling 10 into a closed configuration around the coupling 40 so that the fastener 22 and the through holes 20 in which the fastener is arranged are in axially aligned configuration. In order to completely seal and form the pipe joint, a separate second fastener 42, a nut screw 42 is inserted and disposed within the through holes 20 axially aligned with the safety end 18 of the coupling 10 opposite the coupled end 16. A nut 44 is threaded onto the threaded rod of the nut bolt 42 and held over the nut bolt in an amount in the range of about thirty to two hundred and fifty foot pounds (30-350 foot-pounds) of
    Petition 870190101124, of 10/09/2019, p. 19/36
    17/21 torque, preferably depending on the size of the coupling. [00045] Because the preferred coupling is pre-assembled, the preferred pivot clamp 22 'is secured or partially secured at its ends by the threaded nuts 29. The nuts 29 are preferably secured and secured around the threaded rod portions 26a, 26b of fastener 22 'in the amount of about 60-100 pounds foot or in an amount of torque to provide a secure and secure engagement around threaded rod portions 26a, 26b. Alternatively, the ends 26a, 26b of the fastener 22 'can be secured to the housing components 12, 14 by other techniques such as compression fit, by locking the ends 26a, 26b in place, or by using the ends formed with other secure structures, i.e. ie, pins, as long as the fastener is properly secured and located within the through holes 20 of the bolt damping extensions 16a, 16b and the coupling can satisfy the desired hydrostatic pressure and bending moment rating.
    [00046] The coupling mode 10 described above was sealed using a separate fastener 42 that is installed and secured by the end user. In order to provide a pre-assembled coupling device, preferably completely shown in figures 8A and 8B, it is an alternative embodiment of the coupling 10 '. In this alternative embodiment, the safety end 18 of the coupling 10 'is configured to provide a pre-assembled fastener assembly 42. The preferred pre-assembled coupling 10 'further includes at its coupled end 16 a fastener 22, preferably a pivot fastener 22' that couples the upper housing component 12 and the lower housing component 14 together and provides a pivot shaft PP around of which the component pivots with respect to each other. Although the accommodation component

    Upper 18/21 12 is configured as previously described, the lower housing component 14 'preferably includes a slot 21 at the safety end 18. The slot 21 is in communication with the through hole 20 of the end of the screw damping extension with nut 18b and preferably includes a peripheral slit opening located on the outer side edge of the housing member 14 '. With the slot opening and the slot 21 in the lower housing, a fastener assembly in the form of a combined screw nut 42 and nut 44 can be arranged within the through hole 20 of the screw damping extension end 18a of the upper housing component 12. With the slot 21 communicating with the through hole 20, the nut-bolt damping extension 18b 'provides an elongated or preferably oval-shaped opening for engaging a correspondingly shaped portion of the nut-bolt for prevent rotation of the nut bolt into the through hole 20.
    [00047] The 10 'pre-assembled coupling eliminates the need for the end user to insert a separate nut bolt into the safety end 18 of the coupling and hold a nut around the end of the fastener 42. Instead, the end user can locate the coupling 10 'around the gasket 40 which is arranged around the aligned pipe segments 2, 4. The coupling is then brought into a closed configuration as shown, for example, in figure 8B. Fastener assembly 42, 44 can be positioned out of the way to allow housing components to pivot to the closed position. Once in the closed configuration, fastener assembly 42, 44 can be inserted through slot 21 and its opening in position in through hole 20. A
    Petition 870190101124, of 10/09/2019, p. 21/36
    19/21 nut 44 is then tightened to the desired torque values and the pipe joint can be put into service. Although the slot 21 and its peripheral opening are described with respect to the lower housing 14 ', it is to be understood that the alternative housing component 14' can be used as the upper housing component of the coupling assembly 10. In this case, the assembly of fastener 42 can be pre-assembled within the through hole 20 of the lower housing component.
    [00048] The preferred coupling assemblies above are preferably configured to join a 5.08 cm (two inch (2 inch) nominal pipe or tubing); 6.35 cm (2 inches; three inches (3 inches)); 10.32 cm (four inches (4 inches)); 15.24 cm (six inches (6 in.)); or 20.32 cm (eight inches (8 in.)), but can be configured to join pipe or tubing of any size with the proviso that the housing components are configured to retain and hold pivot clamp 22. On each one of the coupling assemblies described above, pivot clamp 22 in combination with safety clamp 42 provides sufficient distributed compressive force through the housing components around the gasket 40. The inner surfaces 12a, 14a of the upper housing components and lower 12, 14, which engage the gasket 40, preferably define a profile to maximize and / or maintain sufficient compressive force against the gasket in order to maintain an effective seal of the pipe joint.
    [00049] A known internal surface 12a of the upper housing component 12 engaged with a preferred gasket 40 is shown in figures 9A and 9B. Details of an alternate inner surface 12a, 14a and a preferred gasket are shown in figures 10A and 10B for use in a hinge coupling arrangement described above. Respectively shown in the figures

    20/21
    10A and 10B are uncompressed and compressed views in which the conical inner surface 12a of a coupling housing 12 defines a pair of notches 30 which compress the side faces of a preferred gasket 40 laterally against the internal side walls of the housing 12. The description detailed gasket and housing shown in figures 10A and 10B is provided in International Application No. PCT / US10 / 53970, filed on october 25 , 2010 entitled Systems and Methods for pipe couplings, and claiming priority to Application US Provisional Patent Application No. 61 / 255,409, entitled System and Methods for pipe couplings, filed on october 27 , 2009, both incorporated herein by reference. The known gasket configurations can be used with the coupling assemblies described in this document. For example, as shown in figures 9A and 9B, the standard C-shaped or Trivedation gaskets as identified on page 12 in Tyco Fire & Supression Products Publication IH-1000FP, titled Grinnell®- Grooved Fire Protection Installation Manual (August 2007) can be used in the preferred coupling assemblies 10, 10 '. A copy of page 12 from the installation guide is included in US Provisional Patent Application No. 61 / 255,351.
    [00050] In the preferred coupling 10, 10 'and its installation, as described above, the pivot clamp 22 provides at least three functions: i) it couples the housing components 12, 14 together for a pre-assembly that minimizes the number separate components for the end user; ii) the fastener 22 defines the pivot axis of the coupling 10; and iii) in the closed configuration, the fastener 22 provides a secure retention between the housing components 12, 14 so that the user only has to properly torque a fastener 42 to form a fluid tight seal. THE
    Petition 870190101124, of 10/09/2019, p. 23/36
    21/21 assembly of the preferred coupling 10 more specifically provides the preferred fastener 22 which, in its axial configuration, linearly aligns the through holes 20 of the housing components 12, 14 to define the closed configuration of the coupling 10 as seen in figure 5B, and in its inclined configuration, it defines the open configuration of the coupling 10, as seen in figure 5A. Shown in figures 3A-3D and described above is a preferred embodiment of pivot fastener 22 '. However, alternative configurations of fastener 22 and its configuration within components 12, 14 are possible with the proviso that the resulting fastener functions as described. For example, the fastener and the coupling can be configured to retain the coupling in the open and closed configuration with the fastener elements in an inclined configuration. In addition, the fastener can be provided and the nut-bolt damping extensions configured so as not to require the fasteners to extend through a through hole, for example, one or more of the nut-bolt damping includes a threaded blind hole for the pivot clamp rods.
    [00051] Although the present invention has been disclosed with reference to certain modalities, numerous modifications, changes and changes to the described modalities are possible without departing from the scope and scope of the present invention. Consequently, it is intended that the present invention is not limited to the described modalities, but that it has the entire scope defined by the language of the following claims, and equivalents thereof.
