[0005] The disclosure and drawings of U.S. patent application No. 63 / 370,984, filed on August 10, 2022, are incorporated herein by reference in their entirety. Technical Field

[0006] The present disclosure relates generally to pipe fittings. More particularly, the present disclosure relates to apparatus and methods for assembling pipe fittings, couplings or connectors designed to be buried underground. Background Art

[0007] Conduits and pipes are used to transport various media such as liquids and / or gases, and are sometimes used underground. Use couplings, connectors and fittings to connect conduits and pipes in various ways so that conduits and pipes can be arranged in different configurations to move media through conduits and pipes. Conduits and pipes can be rigid, such as metal or plastic pipes used in household plumbing applications, or conduits and pipes can be flexible. Connectors are used for end-to-end connection of pipes and pipes, or connectors can guide conduits and pipes in different directions relative to the axis of the conduit. For example, connectors can be used to change the direction of the pipe, such as at an angle of 45 ° or 90 ° relative to the flow channel of the pipe connected by the connector. Connectors can also be used to branch or separate pipes in different directions. For example, a single pipe section can be connected by a T-shaped fitting, a Y-shaped fitting, a multi-conduit joint or a diameter change.

[0008] A typical method of protecting fittings, such as push-to-connect (PTC) fittings, from environmental and other degradation when buried underground includes the use of silicone wraps. Such silicone tape wraps designed to protect fittings are often time-consuming and cumbersome to use. Summary of the invention

[0031] As used herein, relative directions and the terms "inwardly" and "outwardly" are relative to the longitudinal axis, wherein inwardly is a direction radially toward the longitudinal axis and outwardly is a direction radially away from the longitudinal axis.

[0032] Relative directions and the terms "distal" and "proximal" are used relative to a connector assembly secured to an end of a fluid conduit, wherein the distal direction is toward the end of the connector assembly at the end of the fluid conduit (e.g., the receiving end of the connector assembly), and the proximal direction is toward the beginning of the fluid conduit to which the connector assembly is secured. Relative directions and the terms lateral or laterally are in a plane generally orthogonal to the longitudinal axis.

[0033] Various examples of the present disclosure include an embedded enclosure, which is a sealed housing for direct embedment of, for example, a pipe fitting. The sealed housing provides a substantially airtight and watertight sealed environment to protect the fitting from environmental degradation and other degradation. Other examples include a direct embedment assembly for facilitating direct embedment of, for example, a PTC fitting. The PTC fitting may include a connector body, a sealing member or sealing gasket, a gripping ring, a barrel, a retainer sleeve, a plurality of latches, and an interference portion. The connector body has a fluid passage extending at least partially therethrough. The sealing gasket is configured to form a sealing engagement with a fluid conduit. The gripping ring includes a plurality of teeth configured to be coupled to the fluid conduit. The barrel is positioned adjacent to at least a portion of the gripping ring and has a hollow portion passing therethrough. When assembling a push-on fitting, the gripping ring is between the barrel and the sealing gasket. The retainer sleeve is received on at least a portion of the barrel and is received on at least a portion of the connector body. A plurality of latches are located on the retainer sleeve and are configured to secure the retainer sleeve to the connector body to facilitate retaining the sealing gasket, the grip ring, and the barrel. When the push-on fitting is assembled, the interference portion is interposed between the connector body and the retainer sleeve. The interference portion is configured to engage the retainer sleeve to substantially prevent the retainer sleeve from rotating relative to the connector body.

[0034] In various examples of the present disclosure, the assembly may include a housing or shell that at least partially defines a chamber or cavity, the chamber or cavity being shaped, sized or otherwise configured to receive and hold pipe fittings, such as PTC fittings, push-fit fittings or other pipe fittings, couplings or connectors. The housing or shell may also include a plurality of fluid channel openings, each of which is configured to receive a pipe or conduit for connecting to the fitting. In other examples, the assembly may include one or more sealing gaskets configured to provide a seal between the housing and the pipe or conduit received therein. The seal may substantially prevent, reduce or inhibit the introduction of contaminants into the chamber. In other embodiments, one or more sealing gaskets may also include a plurality of separate or removable portions, which allow selective use of a plurality of openings so that the direct-buried assembly may adapt to fittings with different configurations, such as straight configurations, elbow configurations, T-shaped configurations, star configurations, Y-shaped configurations, etc.

[0035] In various examples, the seal and the housing can be manufactured as a single component by, for example, co-molding or two-shot molding. For example, the housing can be a one-piece folding housing using a living hinge connecting two housing parts, a single seal design can be used in each housing part, and when the housing parts are closed and linked together, the fit can be achieved by using a face seal. Other examples can include a double seal design that uses the fit of interlocking features to form a seal when the housing halves are closed and linked together. The advantages of the examples disclosed herein include that the housing is reopenable, the installation of the housing can be tool-free installation, the installation of the housing is low-cost, and the housing is aesthetically pleasing.

[0036] FIG. 1A to FIG. 1I is an illustration of a protective housing according to various examples of the present disclosure.

Figure 1AIn the embodiment of the present invention, the protective housing 100 includes two shell parts or half shells 110A and 110B connected together via a hinge 120 (such as a living hinge 120), although other schemes are also feasible. The shell parts 110A and 110B each include a corresponding plurality of openings 130A and 130B, and each opening forms a part of a fluid passage when the protective housing 100 is folded at the hinge 120 and the shell parts 110A and 110B are closed together. In various examples, each of the shell parts 110A and 110B includes a shaped cavity, and when the shell parts 110A and 110B are connected together, a fluid passage is formed, such as a sealing gasket (not shown) or a pipe fitting (not shown) can be inserted or arranged in the fluid passage. In various examples, the volume within the enclosure formed when the shell parts 110A and 110B are closed can be about 2.3 cubic inches.

[0037] Figure 1B A sealing gasket 140 is shown according to various examples of the present disclosure. Figure 1B In the embodiment, the sealing gasket 140 includes three sealing plugs 150 and defines fluid passages along two axes "A" and "B". In operation, the sealing gasket 140 can be made of a single molded design and can be inserted into the above-mentioned Figure 1A The two enclosure parts 110A, 110B of the protection housing 100 discussed and accessories (such as pipe fittings or pipe connectors). The pipe fittings can have a straight shape, an elbow shape, a T-shaped shape, a Y-shaped shape or a star shape, as further discussed below. In various examples, the sealing plug 150 can be removable and can be removed to accommodate a conduit or pipe passing therethrough. In various examples, the volume inside the sealing liner 140 can be about 0.64 cubic inches.

[0038] Figure 1C The invention shows a device inserted into the protective housing 100 according to various examples of the present disclosure. Figure 1B The sealing gasket 140 is shown. Figure 1C In the embodiment, two sealing gaskets 140 are respectively inserted into the enclosure parts 110A and 110B of the protection housing 100. Figure 1D The protective housing is shown in operation according to various examples of the present disclosure. Figure 1D In the embodiment, the protective housing 100 is in an open configuration, and one of the first enclosure portion 110A and the second enclosure portion 110B encloses one or more pipe fittings 160 in a fluid configuration. Figure 1DThe pipe fitting 160 is shown in a T-shaped configuration, but the pipe fitting 160 can be arranged in a straight configuration, an elbow configuration, a T-shaped configuration, a Y-shaped configuration, or a star configuration to match the type of fittings received in the protective housing 100. Figure 1D In the example shown, the closure or attachment mechanism 170 is a clasp 170, but may be or include other types of closure or fastening mechanisms, such as wire ties and screws. Figure 1E Another protective housing is shown in operation according to various examples of the present disclosure. Figure 1E In the embodiment, the pipe fittings 160 are in an elbow configuration instead of a T-shaped configuration and are connected together by an elbow-shaped connector 115 configured to form a fluid passage between the two pipe fittings 160 .

[0039] During use, the protective housing 100 can be in a closed configuration, wherein both the first enclosure portion 110A and the second enclosure portion 110B are connected together via a hinge 120 on one side of the first enclosure portion 110A and the second enclosure portion 110B and also via one or more closing or connecting mechanisms 170 at each end of the first enclosure portion 110A and the second enclosure portion 110B, but alternatives are possible. The closing or connecting mechanism 170 is a clasp 170, but can be or include other types of closing or fastening mechanisms, such as, cable ties and screws. For example, the enclosure portions 110A / 110B and the sealing gasket 140 form a fluid passageway that can receive a pipe fitting 160 when in a closed configuration. Due to the configuration of the enclosure portions 110A / 110B and the sealing gasket 140 when the clasp 170 is closed, the sealing gasket 140 and the pipe fitting connection (not shown) inside the enclosure portions 110A / 110B are sealed, e.g., hermetically sealed, and protected from environmental influences. Figure 1D The pipe fitting 160 is shown in a T-shaped configuration, but the pipe fitting 160 can be arranged in a straight configuration, an elbow configuration, a T-shaped configuration, a Y-shaped configuration, or a star configuration to match the type of fitting housed within the protective housing 100. For example, the enclosure portions 110A and 110B form an enclosure having a shaped cavity and define a plurality of openings arranged in at least a trident configuration to receive at least two tubes oriented to match the configuration of a pipe fitting (not shown).

[0040] Figure 1F 1 shows a sealing plug 150 according to various examples, which may include a plug portion 155 integrally formed within a fluid passage formed by the sealing plug 150. In an example, when the sealing gasket 140 is used to protect a pipe fitting or pipe connection therein, the plug portion 155 is removable and can be removed to allow insertion of a pipe fitting 160 (see FIG. 1 ). Figure 1D ), and the sealing plug 150, which may include a pipe fitting 160 (not shown) for a pipe fitting, may then be closed via, for example, a hook 170. In some examples, the plug portion 155 may be removed by cutting the plug portion 155 from the sealing plug 150. In other examples, the plug portion 155 may be removed by punching the plug portion 155 out of the sealing plug 150.

[0041] Figure 1G to Figure 1I is a diagram of a sealing plug 150 according to various examples of the present disclosure. Figure 1G In the embodiment of the present invention, the closed or sealed end 155 is located at the end of the sealing gasket 140 on top of one or more sections 157 and 159. For example, section 157 can have a width of one-half (1 / 2) inch, and section 159 can have a width of three-quarters (3 / 4) inch. Thus, the same gasket 140 can be used for pipe fittings of different diameters (not shown). For example, Fig. 1I As shown, a fitting having a diameter of about 3 / 4 inch may be assembled within the liner 140 by removing the plug 155 and the section 157 so that the pipe fitting may be inserted into the section 159. Similarly, as shown in FIG. Figure 1H As shown, a 1 / 2 inch diameter fitting can be fitted within the liner 140 by removing only the plug 155 so that the pipe fitting can be inserted into the section 157. In various examples, this "step down" configuration can allow the liner to fit pipe fittings of various sizes. Figure 1G and Figure 1H 1 / 2 inch and 3 / 4 inch sizes are illustrated in FIG, but segments 157 and 159 may have various sizes other than 1 / 2 inch or 3 / 4 inch. In addition, although two segments 157 and 159 are shown here, gasket 140 may include more than two segments with different diameters to accommodate a greater variety of pipe fitting sizes.

[0042] exist Figure 1H In FIG. 1 , the liner 140 does not have a plug 155 but is open and can receive, for example, a pipe fitting. By having sections 157 and 159 of different widths, the liner 140 can accommodate pipe fittings of different corresponding widths. Figure 1F , depicts an illustration of a clamping mechanism designed to hold the sealing gasket 140 and the enclosure portion 110A / 110B together according to various examples of the present disclosure. In an example, the sealing gasket 140 and the enclosure portion 110A / 110B can be fixed together via a flange connection 175.

Figure 2C In the embodiment, according to various examples, the protective housing 200 includes: enclosure parts 210A and 210B, which are connected together at their sides via hinges 220; a pipe fitting assembly 290 to be enclosed in the enclosure parts 210A and 210B; a sealing gasket 240, which is lined in the enclosure parts 210A and 210B; and a tie or strap 270, which securely and airtightly encloses the pipe fitting assembly 290 in the enclosure parts 210A and 210B when the sealing gasket 240 is inserted between the enclosure parts 210A and 210B. In an example, the outer surface of the enclosure parts 210A and 210B may be made of silicone or plastic (such as hard plastic), or may include silicone or plastic. For example, enclosure portions 210A and 210B form an enclosure having a shaped cavity and define a plurality of openings 280 arranged in at least a three-pronged configuration to receive at least two tubes 260 oriented to match the configuration of tube fittings 290 .

[0045] According to various examples of the present disclosure, the tube fitting 290 can be inserted into the enclosure portions 210A and 210B, wherein the sealing gasket 240 is between the enclosure portions 210A and 210B and the tube fitting 290 to ensure a snug and / or airtight fit when the enclosure portions 210A and 210B are joined together and closed. For example, the upper or first sealing gasket 240A can be in contact with the enclosure portion 210A, while the lower or second sealing gasket 240B can be in contact with the enclosure portion 210B, and the first sealing gasket 240A and the second sealing gasket 240B can be different parts. Alternatively, the upper or first sealing gasket 240A and the lower or second sealing gasket 240B can be integrally formed. In another example, the upper or first sealing gasket 240A is received in the cavity and arranged along the periphery of the enclosure portion 210A, and the lower or second sealing gasket 240B is received in the cavity and arranged along the periphery of the enclosure portion 210B, and when the enclosure portions 201A and 201B are in a closed configuration, the upper or first sealing gasket 240A and the lower or second sealing gasket 240B form a matching face seal. In an example, when the enclosure of the protective housing 200 is in a closed configuration, the first and second sealing gaskets 240A / 240B together define a plurality of gasket openings 245 (see Figure 2C ).

[0046] In one example, enclosure portions 210A and 210B are connected together via a cable tie 270 when closed (see FIG. Figure 2C ).

In various examples, Figure 2D A T-shaped pipe fitting 290-1 is shown. Figure 2E An elbow-shaped fitting 290-2 is shown, and Figure 2F A straight-line accessory 290-3 is shown. Figure 2D , Figure 2E and Figure 2F In each case shown, the enclosure portion 210A is identical, as described above with respect to FIG. 2A to FIG. 2CHowever, in the case of a linear fitting 290-3, in which only two openings 280 form a fluid passage and can accommodate a tube fitting 260, a removable plug 295 is inserted into the opening 280 that does not receive the tube fitting 260. In various examples, the removable plug 295 is configured to seal one of the multiple openings and ensure that the tube fitting 290-3 remains sealed and protected from the environment. For example, the combination of the sealing gasket 240, the shell portion 210A / 210B and the removable plug 295 provides a snug and / or airtight seal for the tube fitting 290-3 enclosed therein. Similarly, in Figure 2E In the case of the elbow-shaped fitting 290 - 2 shown, a removable plug 295 may be inserted into an opening in the opening 280 that does not receive the pipe fitting tube 260 and still provide a snug and / or airtight seal for the pipe fitting 290 - 2 enclosed therein. Figure 2D Any plugs (such as removable plugs 295 ) are not shown because each opening 280 receives a pipe fitting 260 .

[0048] In other examples, the first and second sealing gaskets 240A / 240B each include a tube portion, and wherein, when the first and second enclosure portions 210A / 210B are in a closed configuration, the first and second sealing gaskets 240A / 240B together form a plug (not shown, but shown as 155 in FIG. 1F ) at one or more of the plurality of gasket openings 245. Additionally, each of the plurality of gasket openings 245 may coincide with a corresponding one of the plurality of openings 280 of the housing.
